In recent years there have been many stories about dryers catching on fire was *. Should we be worried? Yes, of course. We should take seriously anything that can bring our family in danger.
Was the problem the dryer? Rarely.
After review, it is usually determined to catch the vent inside the house fire was, and not the dryer.
The drying process ... ...
When clothes are dried in your family dryer there are two processes happening.First, the heat to the air in the dryer drum is applied, as it rotates. This raises its internal temperature to about 165 degrees Fahrenheit and humidity are causing the clothing sold by evaporation. Secondly, a constant stream of air is passed through the clothes. Surprisingly, the real trick is efficiently dry clothes is not the heat, but this huge volume of air.
Most people think the purpose of ventilation is to heat and fluff outside push.Actually, the main purpose of the moisture out of the house dump. This task must be accomplished easily if the dryer is near an outside wall.
The vent pipe ... ...
In many new houses the laundry room is located in the center of the house, near the family room or kitchen. If on the first floor, it is often possible between the bedroom, easier access to the laundry. Easier access, but the distance from the dryer to an outside wall is much longer. This leads to the core of ourProblem. The vent is either too long or has been limited.
It is harder to push the air through a long vent line as a short. If ventilation is too long, the excess air to the air to misbehave. Hence the moisture and lint accumulate in the vent, rather than thrown out.
To extremes lint can block the ventilation Taken closed. When this happens, the dryer can cause overheating. The normal drum temperature of 165 degrees Celsius canquickly shoot up to 300 degrees Celsius or higher. It can be hot enough to be able to ignite lint in the vent to.
For this reason, manufacturers are now in a maximum venting length of 15 feet. Without the first two elbows.
True vent length ... ...
If you know the true equivalent length of dryer venting, calculate the following:
1. Measure all the straight lengths and add them together
2. Counting multiply the number of turns or elbows, andthis number by 4
3. Add up the totals of steps 1 a.m.-2 p.m.
Example 20-foot venting with 4 turns would actually:
20 m + 4x4 m = 36 feet
Let's be real surprised, by the same length of the vent. In more modern homes can be considerably longer than the manufacturer's recommended maximum.
Watch for these signs ... ...
If the blockage becomes critical the dryer will no longer do their job effectively. As a homeowner, look for the following indications that theVentilation can begin to block.
1 Clothes coming out wet
2 Excess of lint on clothes at the end of the cycle remains
Within 3 dryer damp
4 charger takes too long to dry a load
5 Clothes very hot at the end of the cycle
6 Electrical consumption greatly increased
Because you are not the laundry room the best thing you can do to move to be aware that the phenomenon exists. Consider the venting and cleaning out the lint buildup during youran annual spring cleaning. Also, regularly walk outside and check the vent cap where it exits your house. Remove any lint build and verify the flap moves freely.
If you suspect for any reason that a venting problem turn off the dryer, unplug it and call your appliance service company. Tell them your concerns and ask for their support. As the old proverb goes: "Better safe than sorry".
* There is an average of 14,500 dryer fires annually.
