Clothes dryer self-cleaning filtering device and condensation clothes dryer

Abstract

The invention provides a clothes dryer self-cleaning filtering device, comprising a condenser, a filter screen, an air duct, a water storage box, a water storage tank, and a drainage pump. An upper drain pipe is arranged between the water storage box and the drainage pump. The water storage tank is internally provided with a water level sensor. The device also comprises a spray thrower arranged in the air duct and between the filter screen and the condenser, a lower drain pipe used to connect the water storage box and the spray thrower, a first sensor in the air duct used to sense line chip accumulation on the filter screen, and a controller used to receive signals transmitted by the first sensor and the water level sensor, and respectively send out instructions to control on-off of the drainage pump and the spray thrower. The clothes dryer self-cleaning filtering device is simple in structure, condensed water can be fully used, and the filter screen and the condenser do not need manual cleaning. The invention also provides a clothes dryer using the self-cleaning filtering device. Through adding the spray thrower in the air duct, line chips can be removed in time, the air duct is kept unblocked, clothes drying time is reduced, energy consumption is saved, and manual labor is not needed.

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
