Problems solved by technology

This cleaning method not only has a complex structure and takes up a lot of space, but also the temperature of the condensed water will gradually rise, which is not conducive to improving the heat exchange efficiency. At the same time, the water flows downward by gravity, and the cleaning effect is poor.

Embodiment 1

[0027] Such as figure 1 As shown, the clothes dryer evaporator cleaning device provided by the present invention is installed on the heat pump clothes dryer. The heat pump clothes dryer generally includes a shell, and a drum, a compressor, an evaporator 1, a condenser 2, and a drum are installed in the shell. Flow device, fan, controller, etc., wherein, the condenser 2 and the evaporator 1 are installed side by side under the drum, and both the condenser 2 and the evaporator 1 use finned tube heat exchangers, the compressor, the condenser 2, the section The flow device and the evaporator 1 are sequentially connected through refrigerant pipelines to form a refrigerant circulation system.

[0028] There are hot and dry air inlets and hot and humid air outlets on the front and rear of the drum. There is a certain height difference between the hot and dry air inlets and the hot and humid air outlets to ensure that the hot air can be evenly distributed to all parts of the drum, mak...

Embodiment 2

[0042] Such as Figure 4 As shown, the difference from Embodiment 1 is that there is more than one second spray device 9 in the clothes dryer. The second spray device 9 and the pressure spray head can be fixedly installed at the front door of the drum. The spraying device 9 is also connected with the tap water source 7 through a water pipe.

[0043] After multiple drying cycles, the clothes in the drum are completely dry, and the clothes in this state are particularly prone to wrinkles. In this embodiment, the second spraying device 9 is used to spray the inside of the drum, and the sprayed water mist will fall on the clothes, so that the dried clothes in the drum will be in a damp state, thereby realizing the wrinkle removal of the clothes. Moreover, the rotation of the drum can make the water mist evenly spray to all the clothes in the drum, which is used for the spray head.

[0044] In this embodiment, the second spraying device 9 is connected to the tap water source 7, a...

Abstract

The invention relates to a method for cleaning an evaporator of a clothes dryer, a cleaning device and a clothes dryer. After the drying operation, the first spraying device is used to spray the evaporator, which is mixed with hot and humid air formed after drying to lower the air temperature and Water droplets are deposited on the surface of the evaporator, and the lint attached to the evaporator is taken away by the water droplets flowing along the surface of the evaporator. The water source required for spraying comes from tap water. The invention not only has simple structure and good cleaning effect, but also improves the condensation efficiency of the system through the precipitation of water vapor, achieves the purpose of saving energy, and improves the energy consumption level of the clothes dryer. The water volume is in a relatively stable and less state, which will not have a great impact on the heat pump system of the clothes dryer, thereby effectively ensuring the stability of the heat pump system.

Description

technical field [0001] The invention relates to a clothes dryer, in particular to a method and a cleaning device for cleaning lint dust on an evaporator of a clothes dryer, and belongs to the technical field of clothes dryers. Background technique [0002] Existing dryers, especially heat pump dryers, on the one hand, during the drying operation, some lint will adhere to the evaporator, which will affect the operating efficiency of the dryer after a long time; The energy consumption and condensation efficiency of clothing machines have also encountered bottlenecks. It is difficult to improve by relying on the airtightness of the whole machine and the refrigeration system, and it is necessary to find another way. [0003] Regarding the cleaning of lint, the patent application No. 200880114983.4 discloses a method and device for cleaning components, especially the evaporator of the condensing device, which is obtained by drying wet clothes and collected in the condensate pan. ...
