The heat pump type washing and drying integrated machine in the related art can realize low-temperature drying, and meanwhile, the heat pump type washing and drying integrated machine is more energy-saving than common electric heating type drying, but clothes can generate a plurality of fine flocks in the drying process, and the flocks enter a drying circulating system under the driving of a circulating fan. In order to prevent the drying system from being blocked by the flock, a layer of filter screen is generally arranged in an air outlet channel of the drying system. The smaller the meshes of the filter screen are, the more the fine fluff can be blocked, but when the meshes are too small, the wind resistance of the drying system is increased, and the drying efficiency is influenced. Therefore, in order to ensure the drying effect, the meshes of the filter screen are not too small, which inevitably leads to the situation that the fluff passes through the filter screen to cover the evaporator, thus causing the surface of the evaporator to be easily blocked and affecting the drying efficiency.
To the above situation, the embodiment of the present invention provides a main solution: the operation frequency of the compressor is controlled to frost the surface of the evaporator fin, and then the defrosting program is operated to melt the frost layer on the surface of the evaporator into water and take away the flock attached to the surface of the evaporator.

Of course, the cleaning mode can also be triggered in a manual manner in this step, i.e. the frequency of the compressor is adjusted and the fan is turned on manually. The purpose of this step is to ensure that the temperature of the evaporator surface is greater than 0 ℃.
Step S2, after the surface of the evaporator is condensed, the fan is closed, and the compressor is controlled to operate continuously after increasing the frequency;
circulating air continuously passes through the surface of the evaporator to form condensation, which shows that the evaporator has a frosting condition, at the moment, the operation of the fan is stopped, the frequency of the compressor is controlled to be increased to high frequency for working operation, and the purpose is to reduce the temperature of the surface of the evaporator and create a temperature condition for frosting the surface of the evaporator. The specific judgment method of the evaporator surface condensation can be realized by manual observation and can also be realized by monitoring the dew point temperature. In addition, whether the surface of the evaporator is condensed or not can be judged according to experience of a plurality of tests, for example, when condensation is generated through a plurality of tests, the time of the compressor working under the intermediate frequency is counted, for example, counting finds that when the time of the compressor working under the intermediate frequency is longer than 15min, condensation is generated on the surface of the evaporator, the fan can be turned off after the compressor working under the intermediate frequency is operated for 15min, the compressor is controlled to continuously operate after the frequency is increased, and certainly, when the model of the compressor is changed or the environmental climate where the equipment is located is changed, the time needs to be measured through a test again. Preferably, the high frequency range in this step is 75-90 Hz.
And step S3, when the surface temperature of the evaporator is lower than 0 ℃, starting the fan, and controlling the compressor to continue to operate after the frequency of the compressor is reduced.
After the surface temperature of the evaporator is lower than 0 ℃, the surface of the evaporator can be judged to frost, and after the fan is started and the frequency of the compressor is adjusted to be reduced to the intermediate frequency operation, the surface temperature of the evaporator can be increased, so that the frost layer on the surface of the evaporator is melted, and then impurities such as clothing flock, dust and the like attached to the surface of the evaporator are taken away, and the purpose of cleaning the evaporator is achieved. Preferably, the intermediate frequency range in this step is 45-60 Hz.
The utility model discloses the clean method of evaporimeter can be effectively with attached to impurity such as clothing dander on the heat pump formula all-in-one washer dryer evaporimeter clear away to even make the complete machine use many times after also can not influence follow-up drying efficiency because of having impurity to adhere to on the evaporimeter.

step S3, when the surface temperature of the evaporator is lower than 0 ℃, starting a fan, and controlling the compressor to continue to operate after frequency reduction;
and step S4, when the surface temperature of the evaporator is higher than 0 ℃, the evaporator cleaning mode is exited, and the compressor is closed.
This embodiment is different from embodiment 1 in that step S4 is added, wherein steps S1, S2 and S3 refer to the specific solution of embodiment 1.
In step S4, an exit form of the evaporator cleaning mode is shown, and when the temperature of the evaporator surface is higher than 0 ℃, it can be determined that the frost layer on the evaporator surface will melt, and the purpose of cleaning the evaporator is achieved, and the operation of the compressor and the fan can be finished. And after the heat pump type washing and drying integrated machine exits the evaporator cleaning mode, the compressor is closed, and the fan can be closed at the same time, so that the cleaning is finished. The exiting of the cleaning mode in this step may be automatically completed through program control, for example, the controller determines the temperature of the surface of the evaporator detected by the temperature detection device, and when it is determined that the obtained temperature is greater than 0 ℃, an exiting mechanism may be set to issue a control instruction to turn off the compressor and the fan.
The utility model discloses the clean method of evaporimeter can be effectively with attached to impurity such as clothing dander on the heat pump formula all-in-one washing and drying machine evaporimeter clear away to make the complete machine even use after many times also can not have impurity to adhere to and influence follow-up drying efficiency because of having on the evaporimeter, and can in time shut down after the cleanness finishes, reduce the energy consumption.
