Problems solved by technology

[0002] In the existing home appliances with dehumidification function, the start-stop control of the compressor is controlled according to the air humidity detected by its humidity sensor, that is, as long as the detected air humidity exceeds the preset humidity value of the home appliance, the dehumidification will start. However, in some cases, dehumidification cannot be performed even when the air humidity exceeds the preset humidity value, for example, when the pipe temperature of the dehumidification part exceeds the dew point temperature corresponding to the ambient temperature
This will result in a waste of energy

Embodiment 1

[0045] figure 1 It is a flow chart of a dehumidification control method provided in the embodiment of this application.

[0046] Such as figure 1 As shown, the dehumidification control method applied to household appliances with a dehumidification function provided in this embodiment includes the following steps:

[0047] S101: Determine whether the preset RH is smaller than the RH environment.

[0048] When a home appliance with dehumidification function receives a dehumidification command during operation, it first judges the preset relative humidity RH 预设 Is it less than the ambient relative humidity RH 环境 , the preset ambient humidity is set by a control command.

[0049] S102: Running the fan.

[0050] When the preset relative humidity is greater than the relative humidity of the environment, only the fan of the household appliance will run.

[0051] S103: Judging whether the current temperature satisfies a preset power-on condition.

[0052] The current temperatur...

Embodiment 2

[0064] figure 2 It is a flow chart of a dehumidification control method provided in another embodiment of the present application.

[0065] Such as figure 2 As shown, this embodiment provides a dehumidification control method applied to household appliances with a dehumidification function, including the following steps:

[0066] S201: Determine whether the preset RH is smaller than the RH environment.

[0067] When a home appliance with dehumidification function receives a dehumidification command during operation, it first judges the preset relative humidity RH 预设 Is it less than the ambient relative humidity RH 环境 , the preset ambient humidity is set by a control command.

[0068] S202: Running the fan.

[0069] When the preset relative humidity is greater than the relative humidity of the environment, only the fan of the household appliance will run.

[0070] S203: Judging whether the current temperature satisfies the preset dehumidification temperature condition. ...

Embodiment 3

[0085] image 3 A structural diagram of a dehumidification control system provided in another embodiment of the present application.

[0086] Such as image 3 As shown, the dehumidification control system applied to household appliances with dehumidification function provided by this embodiment includes a first judging module 20 , a control module 10 , a second judging module 30 , a third judging module 40 and a fourth judging module 50 .

[0087] The first judging module 20 is used for judging whether the preset relative humidity is lower than the relative humidity of the environment when the home appliance with dehumidification function receives a dehumidification control command input by the user during operation. The preset relative humidity is derived from the dehumidification control command.

[0088] The control module 10 is used to only run the fan of the household appliance when the first judging module 20 judges that the preset relative humidity is greater than the ...

Abstract

This application provides a dehumidification control method and system applied to household appliances with dehumidification function. The method and system are used to first determine the preset Whether the relative humidity is lower than the relative humidity of the environment, if not, only run the fan of the home appliance, if yes, further judge whether the current temperature meets the preset dehumidification temperature condition, if yes, turn on the compressor, if not, continue to run only the Fans for home appliances. Under the condition that both the compressor and the fan are running, the temperature of the inner pipe of the dehumidification part and the corresponding dew point temperature of the indoor environment are detected every t1. If the temperature of the inner pipe is higher than the dew point temperature and lasts for t2, the dehumidification effect is no longer available, and the dehumidification operation is stopped at this time, so as to achieve the purpose of saving electric energy.

Description

technical field [0001] The present application relates to the technical field of household appliances, and more specifically, to a dehumidification control method and system. Background technique [0002] In the existing home appliances with dehumidification function, the start-stop control of the compressor is controlled according to the air humidity detected by its humidity sensor, that is, as long as the detected air humidity exceeds the preset humidity value of the home appliance, the dehumidification will start. However, in some cases, dehumidification cannot be performed even when the air humidity exceeds the preset humidity value, for example, when the tube temperature of the dehumidification part exceeds the dew point temperature corresponding to the ambient temperature. This will cause a waste of electric energy. Contents of the invention [0003] In view of this, the present invention provides a dehumidification control method and system, which are applied to ho...
