How Dryers Work Dryers are designed to remove moisture from clothing, usually after washing in a washing machine. There are three 3 requirements in order to efficiently dry clothing in a dryer: Heat Tumbling Air Flow Heat: Traditional dryers use a heat source to increase the air temperature and shorten the time for drying clothes.
Tumbling movement : Tumbling is a result of a motor moving the drum of the dryer, allowing the clothing to move around. Air Flow: Air flow may be the most important of the three requirements to dry clothing. As the drum rotates, the paddles lift and tumble your wet clothes until they reach the top of the drum.
Then gravity makes them fall back down through the hot, dry air. Dryers work most efficiently when the wash tumbles through the hot air this way. If you overload them, the wash just bunches up and rolls around in a big ball instead of tumbling and it takes much longer to dry.
The air that leaves the dryer passes through a lint filter that catches dust and bits of fluff. Some dryers have a second exhaust fan to help extract the moist air. To avoid fires, it's essential to clean the lint filter in a dryer regularly ideally, every time you used it. Our th reminder about this to you Exhausted air passes up through a vent hose typically mounted permanently in the ceiling. Gas dryers are combustion appliances.
When they burn gas, they give off deadly carbon monoxide gas that must be vented to the outdoors. Lint can be a serious fire hazard.
So all dryers should be connected to a noncombustible metal vent duct that routes from the dryer to an exterior wall. Let's start by looking at the cycle control knob. By turning this knob to various positions, you can control both the type of cycle and the length of time it runs. Let's take a look at what is inside this switch. Here is a view of the back of the cycle switch. Attached to the back is a little motor.
The picture below shows the motor unscrewed from the switch. The tiny gear on the motor turns very slowly; and it engages a bigger gear inside the switch that makes the switch turn even slower. The motor turns the gear on the dial , which is connected to a set of four cams stacked on top of each other.
Each of the cams engages one of the four contacts in the switch. Each of the four contacts has a bend in it, and each bend is located at a different height inside the box. Starting with the bottom left contact , the heights increase in a counterclockwise manner; the bottom left contact is the lowest, the top left contact is the highest.
A different cam engages each of these contacts. In the pictures below, you can see the four cam layers; each of these layers corresponds in height to one of the contacts. The cycle switch determines how long the elements stay on. In conjunction with the heat setting buttons , it also controls which heating elements are on at a given time.
If none of the heating elements are on, only cool air blows through the clothes; if one is on, the air is warm; and if both are on, the air is hot. If you press any of the top four buttons, they stay depressed. If you then press a different button, the first one pops up, and the new button stays pressed in.
A really neat set of plates that work like the tumblers in a lock make this feature possible, and also control which heating elements are engaged. Inside the switch are a set of four contacts. Depending on which button is pressed in, the plates open or close various combinations of the contacts. The following set of pictures illustrates how pressing the buttons causes the plates to line up in different ways, raising or lowering the bars that make the contacts.
The dryer also has a couple of safety features that help to prevent overheating. There are two temperature shut-off switches. When these switches reach certain preset temperatures, they break contact, which shuts the dryer off.
