Description

Condensate recycling system and clothes dryer

This disclosure claims priority from a Chinese patent application filed with the Chinese Patent Office on July 18, 2018, with an application number of 201810791344.7. The entire contents of the above application are incorporated herein by reference.

Technical field

This document relates to the technical field of clothes dryers, for example to a condensed water recycling system and clothes dryers.

Background technique

The clothes dryer is a household appliance that uses heating to instantly evaporate and dry the moisture in the washed clothes. However, when the washed clothes are put into a dryer for drying, the clothes may have wrinkles (creases, folds, overprints, etc.) due to the characteristics of the material. In order to eliminate such wrinkles, a steam generator or a sprayer is usually provided in the clothes dryer, and water vapor is sprayed on the surface of the clothes during the drying process to eliminate the wrinkles.

Most of the water sources of water vapor in the existing clothes dryer with a water vapor injection function are external tap water or users add pure water by themselves. Tap water is used as the water source. Because the tap water has a large hardness, it is easy to produce scale during the drying process, which affects the steam drying effect, blocks the pipeline, and wastes water resources. The use of pure water requires additional addition by the user, which is inconvenient to use, and also wastes water resources, and the use cost is high.

Summary of the invention

A condensed water recycling system and a clothes dryer are provided herein. The condensed water recycling system and a water source for spraying water vapor from the clothes dryer are provided by a condenser.

This article uses the following technical solutions:

A condensed water recycling system includes:

Condenser
