Embodiment 1

[0033] refer to figure 1 and figure 2 In this embodiment, a heat pump heat exchange system is provided, and the heat pump heat exchange system includes a heat exchange device 4 , a storage box 7 and a flushing device 6 . Wherein, the heat exchange device 4 includes an evaporator 41 and a condenser 42 , and the evaporator 41 and the condenser 42 are housed in the housing box 7 . The flushing device 6 includes an injector, a water inlet mechanism and a drainage mechanism. The injector is located in the holding box 7 and between the evaporator 41 and the condenser 42, so as to be able to spray water to the evaporator 41 and the condenser 42 at the same time; the water inlet mechanism supplies water to the injector; the drainage mechanism communicates with the inside of the holding box 7 , to discharge the water in the holding box 7.

[0034] In the heat pump heat exchange system of this embodiment, the heat exchanger (the evaporator 41 and the condenser 42) is integrated in t...

Embodiment 2

[0045] refer to Figure 4 and Figure 5 , In this embodiment, there is provided a heat pump washing and drying machine or a heat pump clothes dryer, which includes the heat pump heat exchange system described in the first embodiment above.

[0046] The heat pump washing and drying machine or the heat pump dryer can be fully cleaned because the heat exchanger can be fully cleaned without reducing the heat exchange efficiency, prolonging the drying time, and increasing the drying energy consumption due to the accumulation of fluff on the surface of the heat exchanger. High problem, and the cleaning cost is low.

[0047] Further, in this embodiment, the heat pump washing and drying machine or the heat pump dryer also includes a drying chamber 1 and an air duct 2, and the drying chamber 1 can be a drum of a washing machine or a clothes dryer, or can be a cabinet type clothes dryer A drying room for the clothes to be dried. The air channel 2 is connected and fluidly communicated...

Embodiment 3

[0050] refer to Figure 6 , in this embodiment, an automatic cleaning method based on the heat exchange device 4 of the heat pump washer-dryer or the heat pump dryer described in Embodiment 2 is provided, and the following steps are automatically performed after the drying step is completed:

[0051] S1. Water is fed into the injector through the water inlet mechanism, and the injector sprays water to the evaporator 41 and the condenser 42 at the same time, and drains water through the drainage mechanism;

[0052] S2, stop water inflowing into the injector and discharge water from the injector;

[0053] S3, blowing air to the evaporator 41 and the condenser 42.

[0054] Through the automatic cleaning method, the heat exchanger can be cleaned in time to prevent the accumulation of clothing fluff on the surface of the heat exchanger, so that the heat pump washing and drying machine or the heat pump dryer adopting the automatic cleaning method will not have the accumulation of c...

Abstract

The invention relates to the technical field of clothes drying, in particular to a heat pump heat exchange system, a heat pump cleaning and drying all-in-one machine or a clothes dryer and an automatic cleaning method. The heat pump heat exchange system comprises a containing box for containing an evaporator and a condenser and a flushing device. The flushing device comprises an injector arrangedbetween the evaporator and the condenser to spray water to the evaporator and the condenser at the same time, a water inlet mechanism and a drainage mechanism. Compared with the mode that a pluralityof spraying holes are formed in the large region above a heat exchanger, the heat pump heat exchange system only adopts one injector so that the evaporator and the condenser can be cleaned at the sametime, the system is simple in structure and convenient to install, and the cleaning cost is lowered. The heat pump cleaning and drying all-in-one machine or the heat pump clothes dryer comprises theheat pump heat exchange system, the problems that due to the fact that clothes fluff is accumulated on the surface of the heat exchanger, the heat exchange efficiency is lowered, the drying time is prolonged, and the drying energy consumption is increased are solved, and the cleaning cost is lowered. The automatic cleaning method is used for the heat pump cleaning and drying all-in-one machine orthe heat pump clothes dryer.

Description

technical field [0001] The present invention relates to the technical field of clothes drying, and in particular to a heat pump heat exchange system, a heat pump integrated washing and drying machine or a heat pump dryer, and an automatic cleaning method based on the heat exchange device of the heat pump integrated washing and drying machine or the heat pump drying machine. Background technique [0002] A heat pump washing and drying machine or a heat pump dryer is a device that uses a heat pump heat exchange system to heat circulating air, dry clothes, and condense to remove moisture. The heat pump heat exchange system includes a heat exchange device with multiple heat exchangers, and the multiple heat exchangers include an evaporator and a condenser, both of which are composed of a certain number of fins arranged side by side. When drying clothes, the circulating air will contain lint and fluff falling off the clothes. Although the filter installed in the air duct will int...
