Hello, i'm the city's chorus, and i'm focused every day on digging into ordinary human settlementsClearDetails, sharing local gas, home maintenanceCleaningIt's common sense to use electricity. It is the habit of many people, especially in the kitchen areas, to do household chores in a clean mannerRefrigeratorEvery day, food items are stored, the doorknob, the outside side of the fuselage is easily covered with hand stains, oil, sauce residue, and most people clean up with a pot of fresh water and wipe the whole of the fridge from the head to the tail。
This is how many people clean up for more than a decade, and they never have problems, and they admit it's completely safe. But there are a lot of cases of leaks and telegrams in the home electric maintenance industry every year, most of themElectrocutionFrightened, minor electric shocks occurred in the process of cleaning refrigerators with wet rags. The risk of electrical leakage is amplified indefinitely in the damp environment, with the elderly, the infirm population, and children in the family being at risk. Today, in combination with real maintenance cases, national standards for electricity safety, and experience with specialized overhauls, the full removal of the hidden risks of wet rags cleaning refrigerators, the separation of leaks, high-risk clean-up scenes, home-based self-checking methods, and district safety clean-up programmes, have not been exaggerated, all of which are practical knowledge that households can use to avoid electric traps hidden in kitchens。
I. Cases of real-life home repairs in which electrocution caused by wet refrigerators
I visited three local electric repair shops that had operated for more than 10 years, organized three typical events that had taken place in recent years, without theatrical processing, all of which had been experienced by the maintenance master in person, and covered three common scenarios: old refrigerators, new refrigerators for new houses, rental refrigerators, and the use of refrigerators。
The first case occurred during the summer rainy season, with a 62-year-old aunt living on the sixth floor of the old district, where two refrigerators had been used for nine years. The south has been raining for more than 20 consecutive days, and the interior walls and the ground have returned to the tide year after year. The aunt used to wipe the fridge after dinner every day, when she washed the dishes, without drying the water on her hands, and then just twisted a dry wet rag and wiped the metal door handle and side panel of the fridge. In the moment when the finger touched the refrigerator door, a visible electrical current went along the arm to the shoulder, the arm shrunk in an uncontrolled manner, the rag fell directly to the ground, the aunt was scared to step back, the heart jumped, and the arm continued to swell for more than half an hour。
The children contacted the maintenance master on the same day for a door-to-door test, using a specialized leak test instrument, which resulted in an empty electrical pressure of up to 42v in the case of the refrigerator. After the decomposition check, the source was found: the refrigerator was placed in the kitchen wall for a long period of time, the back power line was squeezed and bended year after year, the outer plastic insulation skin was fractured, the internal fuse was naked, and it was attached to the metal backboard of the refrigerator. When the weather is dry, human skin resistance is high and a weak leak is difficult to detect; during the monsoon season, air moisture is overstretched, together with wet rags serving as a conductor medium, and the leak directly affects the body and triggers a sense of shock. The problem of the leak was resolved once the maintenance manager had replaced the whole new power line and re-routed the back line。
The second case was the occupancy of the new house, which had been renovated by the owner for just one year, the refrigerator was a brand-new first-line machine, and the whole of the house was fully paved by the renovation company, and there was no problem of aging the line. The household is a young couple who routinely cleans the back and bottom compressor positions of wet rags that use dripping. A weekend sweep, when the hostess bends over to wipe the gap in the bottom of the refrigerator, the edge of the rag comes across the compressor wire box, the tip of the finger comes in a sting and immediately stops cleaning。
The quality of the refrigerator itself was removed after door-to-door repairs and the failure was eventually locked in the kitchen slot. At the time of the renovation work, the workers were working to reduce the supply, and the kitchen was not connected to the building mainline and was in a state of suspension. Insensible electricity generated by the operation of a completely new refrigerator cannot be imported to the land through the landline, and it accumulates all over the metal box surface. There is hardly any feeling in a dry state, and once extensive areas are wiped with wet rags, water is reduced to human resistance and the sting of sensory electricity is clearly visible. After the replacement of the compliance booth at a later stage, there have been no further cases of twitching。
The third case came from the rental house scene, where the tenant lived on the first floor, the lower floor was prone to rats, and the refrigerator was an old machine left by the landlord. The tenants are easy to clean with sanitary maps on a daily basis and wipe the various corners of the refrigerator with wet rags throughout the course of the day, when the back of the fridge is cleaned one morning. The overhaul revealed the location of the back of the refrigerator near the compressor, the electrical wires gnawed through the insulation layer by rats, direct contact between the fuse and the steel skin of the refrigerator, which was the result of a severe failure of power leak. It's hard to find normal switches and dry handsPerceptions, a full conductive circuit is formed after the wet rags are contaminated, directly triggering electrical contact. Follow-up tenants replaced refrigerators, while the entire house line was screened to eliminate follow-up risks。
A lot of people are looking at this place and they wonder if they've been moisting their refrigerators for years and never been numb. Here, two core concepts must be clarified: sensory power and failure failure, which vary from one hazard to another, are also key points of confusion for the vast majority of households and are the source of the greatest risk of wet rag cleaning。
Ii. Distinguishing sensor power and failure failure failure, understanding the bottom logic of a refrigerator with electricity
In accordance with the national safety of electrical for domestic and similar purposes standards, domestic appliances for metal casings must be equipped with three-foot plugs and designed in a mandatory manner, and such large power appliances as refrigerators, washing machines and water heaters are covered by the compulsory regime. There are only two types of cases in which the outer shell is wired during the operation of the refrigerator, one within normal limits of sensory electricity and the other with a failure of power with a security threat, and the wet rags in a wet environment magnify the two types of electrical incomprehensibleness and risk。
(i) sensor electricity: normal phenomena in refrigerators, ground failure + humidity
There are a number of electrical components in the refrigerator, such as compressors, main circuit boards and heat-dispersion fans, which, in the course of power exchange, generate a trace of co-sensor currents, commonly referred to as sensor electricity. When the formal brand-new refrigerator leaves the factory, the airframe is attached to the groundline, which connects the surface of the wall through a three-legged interpolation, allowing the sensory current to be smoothed into the ground and the normal dry hand to touch the body of the machine in no way different。
Insisting electricity itself is generally in the range of 10v-20v, well below the conventional 36v human safety voltage, highly resistant human hand-held angular layer of electrical resistance in dry environments, and unable to penetrate the human body with weak currents that are completely invisible. However, when two conditions are met, the feeling of discomfort immediately emerges: first, the interpolation line is non-functional and unlocated; and, second, the body is wiped with a fully humid rag。
The piped water contains impurities such as minerals, chlorine ion, which are much more capable of conducting than pure water, and the wet rags attached to metal panels will significantly reduce electrical resistance between the human body and the refrigerator, and the weak sensory electricity will clearly give the feeling of numbing and stinging fingers. Pregnant women, the elderly, high-tension groups and people with injuries on their hands are more sensitive to and responsive to the current。
Sensitivity power does not itself cause serious injury or fatal accidents, but it is an important early warning signal: if it is frequently felt that the iceboxer means that the ground system has been damaged and left out for long periods of time, it can easily escalate into a dangerous failure leak following the ageing of the subsequent route。
(ii) fragmentation: a real lethal hazard, wet rags are electrocutive fuses
The failure is an abnormal charge caused by the damage to the refrigerator's hardware. The leak is generally above 36 v, and in a wet kitchen environment only 12 v, which, when triggered, is highly likely to cause muscle spasms, fall-downs and, in serious cases, severe electrical damage, which is also a priority risk. In combination with the record of 10,000 refrigerators, the failure was mainly due to five core causes, covering the vast majority of households:
1. Aging and breakdown of power lines
Most of the refrigerators are placed in small corners of the kitchen, and routine moves, plugs and plugs, close to the high temperature of the gas stoves and long-term pressure on the cabinets accelerate the ageing of plastics in the outer part of the power line. In refrigerators with a life span of more than six years, the probability of break-up of the power line has increased significantly, and the fuse has exposed itself to metal containers, resulting in the entire machine being charged. It is difficult to conduct currents in a dry environment, and water-scattering occurs instantaneously as a conductor channel through which the currents flow through the human body to the ground and form a complete contact circuit。
2. Cooled water infiltration into internal circuits
Refrigerator operations continue to produce condensed water, and normal drainage paths flow to the bottom of the refrigerator following the internal gallon-guided troughs, with natural evaporation of the work by compressors. Once the steering trough is blocked by food residues, the door seals are rigidly sealed, frequent openings lead to a surge in condensed water volume, the water volume leaks into the back compressor, the area of the wire box, and the vapour impregnated electrical wire insulation layer, resulting in short circuits and fuse casings. During the rainy season, during high summer temperatures, the reported failure of this type will be tripled and the back plate of the refrigerator will be wiped at the bottom of the hour of the accident。
3. Ageing of inner metres
Refrigerators, thermostats, relays, heaters, etc., have a fixed useful life, with long-term uninterrupted work with problems of ageing, insulation and leaking internal currents into metal boxes. Such leaks are initially very hidden and are difficult to detect in day-to-day dry hand touching, which can only be detected when there is water on the hands and extensive wetness. Many households use a refrigerator for more than 15 years, focusing only on cooling, neglecting the ageing of electrical components and the accumulation of hazards。
4. Infrequent interlocking
The old house, the self-built house, the early second-hand room are the most prone to the problem of plugs, and two types of errors are common: one is the absence of a floor line in the kitchen and the complete suspension of the foot of the three-legged floor; and the second is the reverse of the zero-fire line for the construction of the circuit, which results in the continuous electrical charge of the metal casing. In many cases, the same refrigerator is used normally in the living room, leaving it in the kitchen, which is not the problem. The problem is not the refrigerator, the root cause of the problem is the non-conformity of the wall plugs and the central reason for many of the new refrigerator's anonymous leaks. An additional three-legged plug in the refrigerator is used, which directly disables the off-site function and significantly increases the risk of leakage。
Rat bite wire
The first floor, low-level households, old subdivisions are prone to rats drilling into the bottom of the refrigerator, cracks in the backboard, and rats chew on the outer skin of the wire, creating a connection between the fuse and the shell of the refrigerator. Such failures are extremely subtle, there are no anomalies in the day-to-day switch refrigerators, and electricity leaks occur only when the water is clean, and clearance is relatively more difficult。
Wet rags play a key role in magnifying risks throughout the electrocution process. Dry fingers are only single points of exposure to refrigerators and small areas of exposure; wet rags are large enough to fit the airframe, with a wider range of conductives, and currents are more likely to flow through the heart, upper limbs, and if muscles become rigid and people are unable to shake hands on their own, they can increase electrical contact time and increase risk further. In contrast to the national standard safety values, there is a risk of electrocution of excess 12v voltage in a damp environment, often exceeding 50v in an old malfunctioned refrigerator, which is already extremely dangerous。
Three or four high-risk clean-up scenarios, with the vast majority of households per day stepping on pits
In conjunction with maintenance statistics, over 80 per cent of the cases of electrocution in the wet-cleaning refrigerators are concentrated in four types of routine cleaning scenes, where you can check your usual cleaning habits to see if you have a hit。
Scenario one: rag drops of water, directly wipe the backboard of the refrigerator, bottom compressor area
A number of people were cleaning and seeking to be perfectly clean, rags filled with water, while the wipes were dripping down, and the back of the refrigerator was rinded, the bottom cracks, and the power plugs around. The back of the refrigerator, which concentrates all the external lines, the end of the line, and the fittings for the compressor, is itself the area where the condensed water piles and the route has the most broken hair. Dripping into the inside of the fuselage accelerates the aging of the lines, with wet rags directly connected to the electric tank and the human body, with a double risk overlap. Many people do not usually clean the back of the refrigerator, and only after year-end cleaning can it be so intensely wet that it is also the height of the accident。
Scene two: wet, barefoot or thin slipper on the ground, clean refrigerator with water on hand
After the summer drag, the kitchen floor was wet, and many were barefooted, covered in thin ground and towed at home. They had just washed their vegetables, washed their dishes and carried running water with them, and had their hands on the refrigerator. The humid tile ground-guided power is extremely powerful, and if the outer shell of the refrigerator leaks, currents can reach the land directly by hand, torso and feet, forming a closed loop circuit and increasing the sting of electrocution. The kitchens, bathrooms and floors are always damp, at a much higher risk than dry living rooms, bedroom floors, and are also the most common scenes of electrocution among the elderly。
Scene three: old refrigerators with extended service and year-round wet rags to wipe the house
The safe life of refrigerators ranges from 8 to 10 years, in accordance with national norms for the use of domestic electricity, and beyond that period, circuit insulation, sealed glue and electrical components enter the advanced stage of aging. Many families have the same idea of not being bad. A refrigerator is 12 years old, 15 years old or more, and it continues to be rinsed on a daily basis. The previously light-intensity electricity, which slowly turns into a failure of power as the lines age, is accumulated year after year, and when there is a clear sense of shock, the failure is already severe. Many users focus only on the effects of refrigeration, completely ignoring electrical safety, which is a very common area of error。
Scene four: bad-quality plugs, three-foot refrigerator plugs in two-hole plugs. Let's go
Many of the family kitchens were not equipped with sufficient number of plugs, with two-holed plugs, which were inserted behind the wall and the three-legged plugs in the refrigerator. In such cases, the ground leg of the plug is completely suspended, and all of the sensor power in the refrigerator, the failure and the failure to release the electricity, are stored on the surface of the box. If you touch it with water, there's an instant spade problem. In addition to this, the 3c certified low-quality plugs, with their own additional risks such as over-heated internal wires, overheated melting, and self-deficit fires, further exacerbate domestic hazards。
Iv. Zero-basic home-based self-measured three-step approach to fast-tracking of the risk of leaks in refrigerators
There is no need for professional tools, no need to pay to book a repairer, three simple operations, and ordinary people are able to distinguish between normal induction and dangerous failure at home, and it is recommended that each household check itself regularly before the onset of plumes and summer heat, with more frequent tests for older children。
Step 1: dryhand basic touch test
Keep your hands completely dry, take off your slippers, and step on dry wood floors, plastic benches, thick cardboards, etc., insulated objects, touching in turn three positions of refrigerator door handles, left and right side panels, and back metal casings。
If there is only one moment of a very weak sterilisation, then it disappears immediately and normal daily use is free of discomfort, basically normal sensory electricity; if there is continuous atrophy after touch, a sense of pull in the arm, a sense of boredom in the mouth, which, regardless of pain or weakness, is an abnormal leak, all wet rag cleaning is stopped immediately, and the electricity is cut off and repaired by the maintenance staff。
Step two: replace the interpolation comparison test and distinguish between the interpolation problem or the refrigerator problem
Prepare a 3c certifier, confirm a regular local embroidery, plug it in a suitable wall plug to determine the location, such as the living room, bedroom, and remove the refrigerator plug and insert it into the plug, waiting for half an hour of normal operation of the compressor to retouch the body with dry hands。
The complete disappearance of the sterilisation after the replacement of the plug indicates that the original kitchen pluglines were damaged, unlocated, and the zero-fired line was re-connected, and the problem arose in the electrical circuits, with priority being given to the re-routing of the plugs; the replacement of the plugs continued to have a marked aberration, representing the existence of hardware malfunctions in the refrigerator itself, such as the breakdown of the line, the penetration of a meta-piece, etc., and the need to repair the refrigerator。
Step three: micro-contaminated water simulation tests (large area wipes prohibited)
Only a small amount of tap water is extracted from the tip of the finger, with a single touch on the metal part of the refrigerator, and no extensive wipes with a rag. Dry touches have no feeling, only when they are watered, and priority is given to disassembly-checking the plugs for ground failure; dry state touches continue to eject, directly determining a failure of the refrigerator, prohibiting all water purification operations and immediately breaking the cable。
If the test results are more accurate, it is possible to purchase a dozen-dollar home-based phase detector, a simple leak detector, which can be inserted directly into the kitchen plugin, so that one key can detect the breakdown of the ground line, the order of the fire wire, the leaking of the plug, the operation is simple, the value of which is very high, and it is well suited for old neighbourhoods and home-building households。
V. Subregional science clean-up programme, without full drying, clean and secure electricity
Many fear that the oil stains, sauce and water stains on the refrigerator will not be covered by wet rags, but rather that the proper cleaning will be done according to the different areas of the fuselage, which will clean up the persistent stains and completely avert the risk of electrical exposure, divided into four main areas of the fuselage, door seal, back, and inside the refrigerator, with different tools and operational steps, which will be suitable for daily routine cleaning and deep cleaning。
(i) front and side doors of the refrigerator: semi-wet rags are the main, and drip wipes are strictly forbidden
The daily cleaning of doorknobs, freezer doors, side-side plastic panels is followed by a selection of pure cotton coverings, which is then wrinkled to the point where the water drops are completely impervious and then wiped in a semi-humid state. For intransigent stains such as sauce, sauce and oil stains, a small amount of neutral detergent can be used in the clean water to remove the stains, which can be polished with a dry rag, and replaced with a dry rag to dry the remaining water。
Focus on: never use a rag with a full drop of water, and do not flush water into the suture of the refrigerator door, plug in the hole; after cleaning the metal doorknob, it is recommended that the surface be dried with a dry-clothed tail, minimizing the probability of conductivity. Simple daily cleaning, with micro-wet rags, is sufficient to meet cleaning needs。
(ii) refrigerator door seals: soft towels with warm water to avoid flooding into the fuselage
It is easy to jam food residues, slime, where bacteria breed and where many people prefer to wet. Cleaning is done using warm water of about 40 degrees and wet towels, which are fully dryed, and a little bit of the residue is wiped along the glacial gap, and if it is sticky, the edges can be cleared with cotton tags. Do not flush the glue with water to prevent the water from flowing along the cracks into the inner circuits of the refrigerator and accelerate the aging of the circuits. In case of rigidity, deformation and tight seals, the tape is replaced in a timely manner to avoid excess leakage of condensed water。
(iii) refrigerator back, bottom compressor area: wet scrubbing is strictly prohibited, dry wet combined cleaning
The back of the refrigerator, the bottom compressor, and the perimeter of the power line are high-risk areas of leakage, and wet rags and water cleaning are prohibited throughout the process. Day-to-day ash clean-up uses dry chicken dust, dry dust rags to wipe the dust; when heavy oil dust is accumulated, electrostatic dust sheets and dedicated household electric dry wipes can be selected for wipe。
If the back oil is heavily contaminated, the rags can be humid and completely dried, only the outer skin surfaces can be wiped, avoiding wire boxes, power-line interfaces, compressors, and drying with dry cloths once completed and eliminating water residue. When cleaning the bottom of the hose, you can draw it out after the power has been cut, wash it in the sink, dry it and then put it back in place, and not wash it directly under the fuselage。
(iv) refrigerator in-house, refrigerated room: power outage cleaning, safe water
Courage, partitions and drawers in refrigerators are internal closed spaces, isolated from external metal shell circuits and are highly clean and safe. The power is cut early before the depth clean, the food items are removed, the partitions and drawers can be removed and washed into the pool, the inner walls can be wiped with warm water and neutral cleaners, and the refrigerator door is fully ventilated after the cleaning has been completed, confirming that no water has been accumulated before being used. Refrigeration rooms do not extract ice from sharp blades to avoid puncture of the inner larvae, which can naturally melt off electricity and dry up water for reuse。
Additional daily maintenance elements
1. Refrigerators are placed away from high-temperature heat sources such as gas stoves and water heaters, and leave behind back-scatter space of more than 10 cm to avoid the ageing of high-temperature acceleration power lines
2. Refrigerator power lines will not be pulled or bent at will, plugs will be inserted to hold the plug in the main body and will not be drawn
3. After eight years of service, periodic route security tests are conducted with the maintenance master, and a phased replacement of the refrigerator is recommended for extended use
4. Kitchen plugs will be used as separate circuits as far as possible, instead of having multiple large-power appliances in a single slot, giving priority to the use of the wall-body prototype plugs and reducing the frequency of trans-plugs。
Vi. Electronic electronic respects to leave from other weapons in the kids
With the exception of refrigerators, metal-shell appliances such as kitchen washing machines, disinfectant cabinets, microwave ovens and electric water heaters are not recommended to be used to wipe their backs directly with drip wet rags, wired positions, and to follow the principle of “surface half-wet wipe, line area drying, and pre-cleaning”. During the wet season, windows can be ventilated on a regular basis, reducing overall internal humidity and reducing the probability of electrical leakage. The safety of home-based electricity is no small matter, and many accidents result from chronic and insensitive habits, and timely clean-up can protect the safety of the entire family。
While it is important to live in a home and be clean and clean, personal security always comes first. A little wet rag, which looks like a routine routine, has a electrical hazard that many people ignore. Distinguishing between induction and failure, changing the habit of drip-wetting backboards of refrigerators, and periodically self-receiving power leaks avoids the risk of most refrigerator exposure from source。
Topical discussion
Is everyone cleaning the fridge with wet rags? Have you ever had a touch of the freezer? How many years did your fridge take? It would be welcome to leave behind its own experiences and perspectives in the comment area, to follow up on the urban discourse and to continue to share more useful household safety and productive goods。
