In summary, in the air conditioner of the present invention, the dehumidifying device is disposed at the return air inlet, so that indoor air is dehumidified by the dehumidifying device, specifically, the air valve 5 is opened, air enters the front air duct 4 from the return air inlet, the air filter 6 in the front air duct 4 filters the air, then the filtered air enters the first air duct 2, the water-air separation membrane 1 performs water-air separation on the filtered air, and another part of purge air enters the second air duct 3, so as to blow out water molecules separated by the water-air separation membrane 1. According to the invention, through the technology of membrane dehumidification, the technology of switching circulation of return air and dry air is adopted, the indoor humidity is reduced rapidly in a physical mode, the cold and hot circulation of an air conditioner is not influenced, the running state of the air conditioner is not required to be switched frequently when the target humidity is reached, the air humidity can be reduced rapidly by blowing water out of the air duct in a blowing mode, the influence of the dehumidification effect caused by the fact that the dry air is mixed into the room again is avoided, and the problem that the water flows out of the air duct smoothly through a pipeline is avoided.
The invention also provides a control method of the air conditioner, the air conditioner comprises the dehumidifying device in any embodiment, and the control method of the air conditioner comprises the following steps:
step S100: and receiving an air dehumidifying instruction.
Wherein, receiving the dehumidification command may be: the instruction sent by the user through pressing the button of the air conditioner or the terminal equipment such as a remote controller or a mobile phone APP can also be an instruction sent after the air conditioner runs a certain program, for example, when the indoor humidity reaches the user preset highest threshold value during the refrigerating or heating operation of the air conditioner, an air dehumidifying instruction is automatically sent. After the air dehumidifying instruction is sent out, the air conditioner receives the air dehumidifying instruction.
Preferably, after receiving the air dehumidifying instruction, the method further comprises the steps of: judging whether a trigger signal can be obtained; based on the judgment result, whether to control the air valve to be opened is determined.
When the dehumidifying device is installed in place, the signal switch or the pressure sensor is contacted with the dehumidifying device, so that a trigger signal is generated, therefore, when the air conditioner acquires the trigger signal, the dehumidifying device is proved to be capable of being used normally, and the indoor air return function is controlled to be started and the air valve 5 is controlled to be started, namely, the step S200 is performed; when the dehumidifying device is not installed, or a user forgets to install the dehumidifying device, the signal switch or the pressure sensor cannot be contacted with the dehumidifying device, so that the dehumidifying function cannot be used normally, and the control air valve 5 is not opened.
In a word, the air conditioner of the invention determines whether the dehumidifying device is installed in place by detecting whether the triggering signal can be obtained, thereby ensuring that the air dehumidifying is performed after the dehumidifying device is installed in place, and the air dehumidifying is not performed when the dehumidifying device is not installed in place, so that related parts are damaged and unnecessary work is performed. Further, after it is determined that the damper 5 is not opened, the air conditioner transmits a reminding message to remind a user to check and install the dehumidifying device in time, so that the normal operation of the air dehumidifying function is ensured. If the air conditioner is an internet of things air conditioner, the reminding information can be sent to the user through terminal equipment such as a mobile phone/iPad and an intelligent sound box, and of course, the reminding information can also be sent in a mode of generating different alarm reminding sounds and the like through controlling the alarm device.
Step S200: and controlling the indoor return air of the air conditioner to be opened and controlling the air valve to be opened.
After the indoor return air and the air valve 5 are opened, indoor humid air enters the front air duct 4 of the dehumidifying device through the return air inlet of the indoor unit, then the humid air is divided into two parts, namely filtered air and purge air, the filtered air enters the first air duct 2, the purge air enters the second air duct 3, the filtered air enters the inner cavity of the water-gas separation membrane 1 for water-gas separation, and water molecules are separated out of the water-gas separation membrane 1 and then blown out of the room by the purge air in the second air duct 3. Preferably, the air conditioner includes an indoor humidity sensor for detecting indoor humidity.
Step S300: and when the preset condition is met, the air valve is controlled to be closed.
Specifically, an indoor humidity value D1 is obtained, and when the indoor humidity value D1 is smaller than or equal to a preset humidity value, the air valve is controlled to be closed.
More specifically, when |T1-T0| is less than or equal to a first preset temperature value and the first preset humidity value is less than or equal to D1 is less than or equal to a second preset humidity value, the damper is closed.
When the absolute value T1-T0 is larger than the first preset temperature value, and the third preset humidity value is not smaller than D1 and not larger than the fourth preset humidity value, the air valve is closed.
Wherein, T1 is an indoor temperature value, and T0 is an indoor temperature value preset by a user; the fourth preset humidity value is smaller than the first preset humidity value.
Specifically, when the indoor temperature value T1 and the user preset indoor temperature value T0 differ greatly, the indoor humidity value D1 is kept between the third preset humidity value and the fourth preset humidity value, the low humidity can promote human body heat exchange, discomfort caused by the large difference between the indoor temperature and the preset indoor temperature is reduced, when the difference between the indoor temperature value T1 and the user preset indoor temperature value T0 is small, the indoor humidity value D1 is kept between the first preset humidity value and the second preset humidity value, the user feels more comfortable under the more comfortable temperature, the air valve 5 is closed when the indoor humidity reaches the preset humidity interval, and the air dehumidification is finished.
The first preset temperature value, the first preset humidity value, the second preset humidity value, the third preset humidity value and the fourth preset humidity value are preset values preset by a program, can be obtained based on experimental data, can be obtained based on an empirical formula, and the like, and can be set as required by a person skilled in the art. For example, the first preset temperature value is 5 ℃, the first preset humidity value is 40%, the second preset humidity value is 50%, the third preset humidity value is 30%, the fourth preset humidity value is 38%, the comfort humidity of the user is between 40% and 50% when the indoor temperature is less than 5 ℃ different from the user preset temperature, and the comfort humidity of the user is between 30% and 38% when the indoor temperature is more than 5 ℃ different from the user preset temperature. The humidity in the room is continuously regulated through the dehumidifying device and the humidifier, so that the temperature and the humidity in the room can be always kept within a comfortable range.
In addition, although the above embodiment is described in terms of acquiring the indoor temperature value and the indoor humidity value and performing the related control according to the magnitudes of the indoor temperature value and the indoor humidity value, it is not intended to limit the scope of the present invention, for example, the present invention may not acquire the indoor humidity value and the indoor temperature value, but control the air valve 5 to close after the air valve 5 is opened for a preset time, and the like, which are all within the scope of the present invention. In addition, when the indoor humidity reaches the preset humidity value interval, the air valve 5 can be continuously opened for a period of time, and the like, and all the alternative modes are within the protection scope of the invention.
After the air valve 5 is closed, the indoor return air can be directly closed, or the indoor return air is continuously operated for a period of time and then is closed, or the indoor return air can be further or alternatively not closed, as long as the indoor return air can provide dehumidified air after the air valve 5 is opened, the invention does not limit the closing time of the indoor return air, and the invention is limited in the protection scope of the invention.

In another embodiment, after opening the damper 5, the first fan 7 and the second fan 8 are controlled to be turned on. If the wind speed of the return air inlet is too small, the wet air is not enough to enter the first air channel 2 for dehumidification, and the air in the second air channel 3 is not enough to blow water molecules out of the second air channel 3, an additional fan is needed to increase the wind speed in the air channel.
Specifically, a wind speed sensor is arranged at the return air inlet. Specifically, the wind speed at the return air inlet is detected, and when the wind speed is greater than or equal to a first wind speed threshold value after the wind valve 5 is opened, the wind valve 5 is controlled to be continuously opened. When the wind speed is smaller than a second wind speed threshold value, the first fan 7 and the second fan 8 are controlled to be started; when the wind speed is still smaller than a second wind speed threshold value after the first fan 7 and the second fan 8 are started for a second preset time, the air valve 5 is closed, and error reporting information is sent, wherein the second wind speed threshold value is smaller than or equal to the first wind speed threshold value.
Specifically, when the wind speed is greater than or equal to the first wind speed threshold value, the wind power of the humid air enters the first air duct 2 to dehumidify, and also enters the second air duct 3 to blow out water molecules outside, and when the air valve 5 is opened for a first preset time, the air dehumidification is completed, and then the air valve 5 is controlled to be closed. When the wind speed is smaller than the second wind speed threshold value, the wind speed cannot be satisfied to enter the first wind channel 2 for dehumidification, and also cannot be satisfied to blow out water molecules in the second wind channel 3 outside, therefore, the first fan 7 and the second fan 8 are started to assist in supplying air to the first wind channel 2 and the second wind channel 3, if the wind speed of the return air inlet is still smaller than the second wind speed threshold value after the first fan 7 and the second fan 8 are started for a second preset time, error reporting information is sent to require a user to check whether the return air inlet of the air conditioner is normal.
The first wind speed threshold value and the second wind speed threshold value are two fixed values preset by a program, and can be obtained based on experimental data, or can be obtained based on an empirical formula; the first preset time is related to an indoor space to be dehumidified, and the larger the indoor space is, the larger the amount of air to be dehumidified is, and the longer the operation time of the damper 5 is. If the air conditioner is an internet of things air conditioner, the error reporting information can be sent to the user through terminal equipment such as a mobile phone/iPad, an intelligent sound box and the like, and of course, the error reporting information can also be sent in a mode of generating different alarm prompt sounds and the like through controlling an alarm device for the air conditioner.
In addition, although the above embodiment is described with reference to acquiring the wind speed of the return air inlet and performing the related control according to the wind speed, it is not intended to limit the scope of the present invention, for example, the present invention may also be used without acquiring the wind speed value, and it is within the scope of the present invention to open the first fan 7 and the second fan 8 at the same time when the air valve 5 is opened.
