In the modern fast-paced life, the dryer is like a close domestic partner, quietly brings convenience and comfort to our lives. However, when he suddenly lost his temper and couldn't dry his clothes, the convenience became a problem. In fact, the dryer drying is not an insurmountable problem. Next, I will analyze the possible causes of incomplete drying one by one, and provide you with practical solutions.

(1)、Ventilation system

The normal operation of the dryer can not be separated from a good ventilation system. Once the ventilation system has problems, it will directly affect the drying effect.

1. blocked ventilation ducts

①. Reason

The ventilating pipe is blocked, the hot gas can not be discharged smoothly, and the drying efficiency is naturally greatly reduced. Common causes of clogging include accumulation of villi, attachment of dust, or entry of foreign bodies.

②. Solutions

Clean ventilation duct regularly, use long handle brush or vacuum cleaner to remove internal dust, ensure smooth and unobstructed duct wall. At the same time, check whether the exhaust pipe is tightly connected to avoid air leakage.

2. the design of the exhaust pipe is unreasonable

①. Reason

The exhaust pipe is too long, too bent or too small in diameter, increasing airflow resistance, resulting in poor hot gas discharge.

②. Solutions

Optimize the layout of the exhaust pipe, shorten the length, reduce the bending, and ensure that the diameter of the exhaust pipe matches the air outlet of the dryer. If conditions permit, a straight-through exhaust pipe can be used to maximize the efficiency of hot air exhaust.

3. external ventilation environment

①. Reason

If the end of the exhaust pipe is blocked or installed in the wrong position (such as near the wall, windows, etc.) , the heat may be back to the room, affecting the drying effect.

②. Solutions

Move the end of the exhaust pipe to an open area to allow hot air to escape freely. At the same time, avoid placing obstacles near the exhaust pipe to maintain ventilation.

(2)、Heating system failure

The heating system is the core part of the dryer to produce heat. If it fails, the dryer will not be able to play a normal drying function.

1. heating element damage

①. Reason

If the heating element is damaged (e. g. , broken heating pipe, broken gas valve, etc.) , the dryer will not produce enough heat to evaporate the moisture in the clothes.

②. Solutions

Check the appearance of the heating element is intact, there is no scorch or fracture marks. If problems are found, change the heating element in time.

2. thermostat failure

①. Reason

The thermostat acts as an intelligent steward of the heating system, monitoring and regulating the temperature in the dryer. If the temperature controller fails, may cause the dryer prematurely stop heating or continue to heat more than, thereby affecting the drying effect.

②. Solutions

Use a thermometer to measure the actual temperature in the dryer and compare it with the set temperature. If there is a significant difference, it may be a temperature controller failure. At this point, the need to contact professional maintenance personnel to replace the thermostat.

(3)、Load and Operation Problems

In the use of dryers, the load and the choice of operating procedures on the drying effect has an important impact.

1. excessive or inappropriate clothing

The load of the dryer directly affects the drying effect. If put too much clothes at one time, or mixed with absorbent materials (such as thick quilts, towels, etc.) , the dryer will be difficult to dry all clothes in a short time.

2. solutions

According to the capacity of the dryer reasonable distribution of clothing, to avoid overload operation. At the same time, the clothes with strong water absorption are dried separately from the common clothes to improve the drying efficiency.

2. faulty selection of procedures

①. Reason

Program selection is also a key factor affecting the drying effect. By mistake, the dryer may not be able to dry the clothes completely within the set time if the low temperature mode or short time program is selected.

②. Solutions

Select the appropriate drying procedure based on the material and humidity of the clothing. For heavy clothing, choose a high-temperature mode or a long-term program; for light clothing, choose a low-temperature mode or a fast program.

(4)、Inadequate maintenance of equipment

Dryer in the long-term use process, if the lack of necessary maintenance, its performance will gradually decline, resulting in incomplete drying.

1. dust accumulation in condensers/evaporators

①. Reason

As one of the core components of dryer, the cleanliness of condenser/evaporator directly affects the drying effect. If the condenser/evaporator dust too much, will affect the heat exchange efficiency, resulting in incomplete drying.

②. Solutions

In order to ensure the efficient operation of the equipment, be sure to regularly and thoroughly clean the condenser and evaporator surface dust and fluff. For removable type, carefully remove, rinse with water repeatedly until clean; for non-removable type, with a soft brush along the texture, gently and carefully brush away every dust, to ensure no residue.

2. sensor Failure

①. Reason

The sensors are like the smart eyes of a dryer, sensing moisture to control drying time. If it is contaminated and damaged, the dryer can not accurately judge the dry and wet, resulting in improper drying time and serious damage to the drying effect.

②. Solutions

Strictly implement the regular inspection system, carefully look at the surface of the sensor is clean, there is no stain. If the sensor is found to be contaminated, immediately with a cotton swab dipped in alcohol, gently wipe repeatedly to ensure complete removal of stains.

Conclusion

There is no mystery why the dryer doesn't dry. Through the scientific investigation of ventilation system, heating system, load and operation and equipment maintenance and other aspects of the problem, we can often quickly find the root cause and solve it. Let us with scientific attitude and method, let the dryer again become a good helper, for our life to bring more convenience and comfort.
