Description

A lint filter device of a clothes dryer and the clothes dryer

technical field

The invention relates to a lint filtering device for a clothes dryer, in particular to a three-layer lint filtering device for a clothes dryer.

Background technique

Household electric washing machines are divided into pulsator washing machines, drum washing machines, and agitating washing machines. Household electric washing machines are driven by electric energy and rely on the mechanical action of pulsators, drums or stirring blades to wash clothes. With the development of society, washing machines have become common household appliances. , and the living standards of consumers have improved, and the individual needs have been constantly updated. Consumers have increasingly perfected the functions of washing machines, such as being able to not only wash clothes but also dry clothes. Therefore, washing machines and clothes dryers with drying functions have emerged and gradually universal. Take the clothes dryer as an example. The clothes dryer puts the dehydrated clothes into the drum. During the rotation of the drum, hot air is input from the air inlet into the drum to dry. The hot air is discharged from the outlet, so that the hot air circulates continuously to achieve the effect of drying clothes. When the clothes dryer is working, as the drum rotates and the clothes tumble, there will be a small amount of laundry lint in the drum, which moves with the airflow. In order to prevent lint from entering the air duct, the hot air circulates through a filter to filter debris in the air flow. The hot air will continue to blow through the clothes to the filter and then enter the air duct. For the heat pump dryer, if there are too many wind shavings entering the air duct, it will block the evaporator and condenser, making the evaporator and condenser Poor results, which ultimately result in poor drying of clothes.

The current existing method to solve this problem is to fix an ordinary filter screen on the plastic part, and place the plastic part at the air duct opening, near the front panel, and make it into a structure that is easy to disassemble, so as to facilitate removal and cleaning. Disadvantages of the existing method: there are many wind shavings in the air path of the heat pump dryer, and the blockage is serious, which will cause the drying effect to deteriorate and waste energy; As a result, the load of the clothes dryer becomes larger, and when working for a long time, there will be a safety hazard to the parts of the whole machine. Another existing approximate solution is to clean up the lint by the impact force of water by flushing water. When the lint is stuck in the screen hole, this method cannot guarantee the effect and can not eradicate the clogging phenomenon; meanwhile, it increases the cost and wastes water, so it has not been widely adopted.
