Description

Automatic cleaning filter device and laundry treatment device

Technical field

The invention belongs to the field of washing machines or clothes dryers, and in particular to a filter device and a laundry treating device for automatic cleaning.

Background technique

In the process of drying the clothes, especially when the clothes have a low moisture content, the fine fluff on the clothes will be peeled off by the circulating air in the cylinder, and then enter the condenser of the dryer, although the fluff will be dried. The primary filter of the coat opening is filtered, but the fine fluff also passes through the primary filter to the condenser area and adheres to the fins of the condenser.

At present, there are two main aspects of cleaning the condenser technology: first, manually remove the condenser and put it under the faucet for rinsing; second, use the condensed water collected during the drying process of the dryer to directly dry the dryer. The condenser of the machine.

Manually disassembling the condenser for rinsing takes time and effort. If the user forgets to clean, the condenser will be seriously blocked, which will affect the drying efficiency and drying effect. Multiple disassembly will affect the sealing between the condenser and the air duct. The leakage of water vapor causes air humidity in the environment around the dryer, and this solution requires an opening on the front panel of the dryer to install a filter for the condenser or condenser, which affects the overall front panel of the dryer. Exterior.

The design of the flushing condenser using the condensed water collected by the dryer eliminates the need for the user to manually disassemble the condenser, but the amount of condensed water in the tank is limited, and the cleaned scraps are collected again in the tank, which may cause drainage.
