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] Judging the current te...

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

The invention provides a dehumidification control method and system which are applied to electric appliances which have a dehumidification function. According to the method and system, the electric appliances which have the dehumidification function judge whether preset relative humidity is lower than the relative humidity of the environment after receiving a dehumidification command sent by a user during operation, only draught fans of the electric appliances operate if not, whether the current temperature meets a preset dehumidification temperature condition is further judged if yes, compressors are started if yes, and only the draught fans of the electric appliances operate if no. Under the condition that both the compressors and the draught fans operate, the intra-tube temperature of a dehumidification part and the dew point temperature corresponding to the indoor environment are detected at intervals of t1, dehumidification is continued if it is detected that the intra-tube temperature of the dehumidification part is lower than the dew point temperature corresponding to the indoor environment, and if it is detected that the intra-tube temperature is higher than the dew point temperature for a period of t2, the dehumidification effect is invalid, dehumidification is stopped, and then electric energy is saved.

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...
