Almost every household in the united states has a dryer, with millions of new factories coming out each year, which cost $3,400 for 10 years. But it took a lot of people years to tell us what the tube in the back was doing and how the water was evaporated inside the machine. Today, the core and internal structure of the machine will be removed, the work of the dryer, the role of the various components, the day-to-day use of what needs to be understood, and all at once。
Check out the dryer core parts
Open a dryer for domestic use, which consists mainly of four core components: a rotor for clothing, a heater for air, a winder and a leaf wheel to blow the heat into the rotor, and an exhaust pipe from the back of the machine to the outside. The motor drives both the rotor and the leaf wheel, and during the rolling the wet clothes are repeatedly wrapped in hot air, and the water adsorbed in the fibre is taken away by a little evaporation。
The rotor's rotation speed is fixed at a positive or the opposite speed, with the aim of allowing the clothing to flip evenly and each fabric to be fully exposed to the hot wind. The wheel breathed the heating air from the bottom of the machine into the rotor, and the current covered the vapour from the vent to the outside. The entire machine is largely unsophisticated by complex electronic components and is mainly dryed by mechanical structures, so that the cost of manufacturing is low, the failure rate is low, and the normal use of one for eight years is not problematic。
How do you get the hot air
The principle is actually straightforward. The heater lifts the air temperature to 60 to 80 degrees celsius, the hot air flows through the surface of the wet clothes, the water inhaled in the fibres is heated into water vapour, and the continuous flow of the wind removes the vapour from the clothes. The amount of water contained in clothing is declining until the prescribed dryness is reached. The whole process, like the drying of clothes in the sun, is much faster, and the wind and rain do not affect it。
Two types of heating are common in domestic dryers: ptc semiconductor heating and electric heating. Ptc heaters are made of semiconductor materials, which automatically reduce power based on real-time humidity of clothing, and the smaller the dry output of clothing, which saves electricity and keeps the temperature in a safe zone and makes it difficult to burn silk fibres. The electro-hot wire heating structure is the simplest and the lowest cost, but the temperature accuracy is lower and is largely driven by the thermostat。
How does the thermostat protect your clothes
The dryer is typically equipped with two thermostats, one manually setting an automatic protection. The threshold for the thermostat is usually set at 65°c, and when the temperature in the rotor is above that value, the heating tube immediately breaks off and stops heating; when the temperature is below 65°c, the heating tube continues to function. The mechanism prevents local overheating, avoids deformation of fibre-optic fabrics and puts electrical fire risks at a low level。
Temperature sensors are generally fixed to support the rotor and transmit the temperature signal inside the cylinder to the control panel in real time. The control panel consists of two types of computer board control and mechanical program controller, which determine when the heating will stop and when the cooling will go according to the preset time or temperature signal. The cooling stage windmills continue to turn but are not hot, so that the temperature of the clothing can be reduced to near the temperature of the room before opening the door for clothes, which are warm and not hot, and which are difficult to wrinkle。
The exhaust is the only exit from the steam
Many people think the dryer evaporates the water into the air, and in fact the steam is drained from the vent that leads to the outside. For each barrel of dry clothing, the water vapour discharged is converted into liquid water in quantities of almost one or two cups of mineral water. If the vents are not connected, reversed or blocked, the humidity is suffocated indoors, the walls return to the tide and the air is heavy, and it is hard to live。
The vent interface is behind the machine and the tube is kept as short as possible, with as few bends as possible, and the pipe is typically four inches. Millions of dryers in the united states run at the same time each year, and the total amount of water vapour discharged is significant. Too many bends, too long, would increase wind-wind resistance, the drying time would be significantly longer, electricity costs would rise, and there would also be damage to clothing fibres in the drums at high temperatures. Make sure the pipes get out as straight as possible when they're installed。
Dry cleaners and dryers are not the same thing
Many talk about dry cleaning and drying, but it's not much. The dryer was used in the home to process wet clothes after the water had been washed and the water was taken away by the hot wind. The dry cleaner uses solvents such as oil or perchloroethylene, which are chemically dissolved to pollute, without a drop of water. International dry cleaners are common and completely closed, differentiating between dry recycling systems, and tetrachloroethylene is recommended to be completely closed to reduce solvent volatilisation into workshop air。
There are numerous internal modules for dry cleaners: washing, filtering, distillation, drying and recycling systems, plus solvent tanks and pumps. The electrons provide de-fouling mechanical power in reverse through belt-led rollers, high-speed rotation provides centrifuge de-liquidation, and the drying phase allows clothing to flip the accelerator to evaporate. A complete set of equipment can also be equipped with modules such as soap, gas compression, automatic decontamination, which are far more complex than home-based dryers and much more difficult to maintain on a daily basis。
Don't ignore these things in everyday use
All the coins, keys and little clips in the pockets are removed before drying, and metal pieces at high temperatures are burned directly into clothing. The velvet filters of the inner walls of the rotor are pulled out every time, the filters block the wind speed and double the drying time easily triggers overheating protection. The safety switch on the door, if broken, will not activate the machine without it, and it is a real security hazard not to tie the door with tape。
Don't overstretch it at a time, it's flipping in the rotor, and it's drying in the inside and it's white. The ptc-type automatically adjusts power, and the electro-hot wire-type recommends manual setting of time before opening the door to determine whether to extend it. The tampons in the interior of the exhaust pipe are pumped with a vacuum cleaner for six months, ensuring a smooth ventilation, drying efficiency and machine life. And don't use dryers as heaters in winter. That's not design。
How long does your dryer have to dry? Is it always dry or is it too long to wear clothes? The comment section talks about your drying habits and car flipping experiences, and if it's useful, it's just a compliment to someone at home who's still working on wet clothes。
