Clothes dryer self-cleaning filter device and condensation type clothes dryer

Abstract

The invention provides a self-cleaning filter device for a clothes dryer, comprising a condenser, a filter screen, an air duct, a water storage box, a water storage tank, a drainage pump, an upper drain pipe is arranged between the water storage box and the drainage pump, Set the water level sensor, including the sprinkler, which is set in the air duct, between the filter screen and the condenser, and the lower drain pipe, which is used to connect the water storage box and the sprinkler; the first sensor, located in the air duct, senses the water on the filter screen Amount of lint accumulation; the controller, receiving the signals transmitted by the first sensor and the water level sensor, sends commands to control the opening and closing of the drainage pump and the sprinkler respectively. The self-cleaning filter device of the clothes dryer has a simple structure, the condensed water can be fully used, and manual cleaning of the filter screen and the condenser is not required. The present invention also provides a clothes dryer using the self-cleaning filter device. By adding a sprinkler in the air duct, it can remove lint in real time, keep the air duct unblocked, reduce drying time, save energy consumption, and save manpower at the same time.

Description

technical field [0001] The invention belongs to the technical field of clothes dryers, and in particular relates to a self-cleaning filter device for clothes dryers and a condensing clothes dryer. Background technique [0002] Compared with the in-line dryer, the condensing dryer does not emit moisture to the surrounding environment due to the condenser in the circulating air duct, and has little impact on the surrounding environment while drying quickly, so Loved by people. The working principle of the condensing dryer is: the motor drives the fan to make the air flow in a directional circulation in the closed air duct. After the clothes are washed and dehydrated, they are put into the drum of the dryer. After the air is heated by the heating element, it enters the drum. After the clothes are heat-exchanged, the water vapor is taken away. When the humid air passes through the condenser, the moisture is cooled down. The cooling water is pumped into the water storage box by ...

AI Technical Summary

Problems solved by technology

[0003] The water circulation system of the traditional condensing dryer is one-way. After the water vapor is cooled, it is directly drained or dumped. The condensed water is not used. A detachable filter is installed in front of the condenser. After the cycle is over, the customer is required to clean the filter screen in time, and then reinstall the cleaned filter screen, and the condenser needs to be cleaned about once a month, which is labor-intensive and time-consuming
