With reference to FIGS. 1-6 , an embodiment of the present disclosure provides a waterless humidification module and an air conditioner.

The waterless humidification module provided in the embodiment of the present disclosure includes a housing 1, a bellows 2, a humidity control disk 3, a heating component, a first The housing 1 is provided with an air inlet and an air outlet; the air box 2 is located in the housing 1, and the air box 2 has a built-in partition 4 to separate the air cavity in the air box 2 into a first air cavity 22 and a second air cavity 21, and to separate the air inlet of the air box 2 into a first humidity control area 32 and a second humidity control area 31; the humidity control plate 3 is rotatably arranged at the air inlet of the air box 2, and the humidity control plate 3 is used to absorb moisture in the air; the heating component is used to preheat the air, and the heating component includes a first heating element 102 and a second heating element 101, and the first heating element 102 is used to heat the air. The heating element 102 is located above the first humidity adjusting zone 32, and the second heating element 101 is located above the second humidity adjusting zone 31; the first air blower 52 is fixed on the wind box 2, the air inlet of the first air blower 52 is connected to the first air cavity 22, and the air outlet of the first air blower 52 is fixed on the air outlet of the shell 1; the second air blower 51 is fixed on the wind box 2, the air inlet of the second air blower 51 is connected to the second air cavity 21, and the air outlet of the second air blower 51 is connected to the air conditioner indoor unit through the air supply pipe 13.

Specifically, under the dehumidification condition, the second blower 51 operates to form a negative pressure, so that outdoor wet air enters from the air inlet of the shell 1 of the waterless humidification module, passes through the second humidity control area 31 of the humidity control disk 3 and enters the second air cavity 21. When the air passes through the humidity control disk 3, the rotating humidity control disk 3 continuously absorbs the water vapor in the stored air in the second humidity control area 31, and the wet air is converted into dry air and enters the second air cavity 21, and then is sent to the room through the second blower 51. After the humidity control disk 3 is saturated with moisture, the first blower 52 operates to form a negative pressure, and the outdoor air enters from the air inlet of the shell 1 of the waterless humidification module, passes through the first heating element 102 to heat the air to form hot air, and then passes through the first humidity control area 32 of the humidity control disk 3 and enters the first air cavity 22. When the air passes through the rotating humidity control disk 3, the hot air evaporates into water vapor through the water originally absorbed and collected, and the hot air carries the water vapor and is converted into warm and wet air, which is discharged from the shell 1 of the waterless humidification module through the first air cavity 22 and the first blower 52. By reprocessing the moisture removal of the humidity conditioning disk 3, the dehumidification effect of the humidity conditioning disk 3 is improved, and the problem of poor dehumidification capacity of the waterless humidification module is solved.

It can be understood that when the indoor humidification condition needs to be operated, the first blower 52 works to form a negative pressure, so that the outdoor wet air enters from the air inlet of the shell 1 of the waterless humidification module, passes through the first humidity control area 32 of the humidity control disk 3 and enters the first air cavity 22. When the air passes through the humidity control disk 3, the rotating humidity control disk 3 continuously absorbs and stores water vapor in the air in the first humidity control area 32, and the wet air is converted into dry air and enters the first air cavity 22, and then is sent to the outside of the shell 1 of the waterless humidification module through the first blower 52. After the humidity regulating disk 3 is saturated with moisture, the second blower 51 runs to form negative pressure, and outdoor air enters from the air inlet of the shell 1 of the waterless humidification module. The air is heated by the second heating element 101 to form hot air, and then enters the second air cavity 21 through the second humidity regulating area 31 of the humidity regulating disk 3. When the air passes through the rotating humidity regulating disk 3, the water originally collected by the hot air is evaporated into water vapor, and the hot air carries the water vapor and is converted into warm and humid air, which is delivered to the room through the second air cavity 21 and the second blower 51 to deliver warm and humid air to the room.

Optionally, the waterless humidification module further includes a damper 23 rotatably disposed on the wind box 2 for opening or closing the second air chamber 21 .

Specifically, under the humidification condition, the damper 23 is opened, the first blower 52 operates to form a negative pressure, and a portion of the housing 1 After being heated by the second heating element 101, the air forms hot air, which passes through the rotating humidity regulating disk 3 and is converted into warm and humid air and enters the second air cavity 21. Another part of the air directly enters the second air cavity 21 through the damper 23. After mixing, the air is sent to the room through the second air supply fan 51 to provide a large amount of warm and humid air, thereby solving the problem of small air supply volume in the waterless humidification method.

It is understandable that the opening angle of the damper 23 can be set according to the user's choice of air volume. When the user wants efficient humidification, the damper 23 can be closed to allow all the air to enter the second air chamber 21 through the humidity regulating disk 3 and be delivered to the room through the second blower 51 to provide high-humidity air. When the user needs a large air volume, the opening angle of the damper 23 can be adjusted so that part of the air flow enters the second air chamber 21 through the humidity regulating disk 3, while the other part of the air flow directly enters the second air chamber 21 through the damper 23, thereby increasing the fresh air volume while humidifying, thereby meeting the different needs of users.

Optionally, the dehumidification mode of the waterless humidification module includes a moisture absorption process and a dehumidification process. The moisture absorption process turns on the second air blower 51, and the dehumidification process turns on the first heating element 102 and the first air blower 52.

Since the air flow paths of the dehumidification process and the moisture absorption process of the waterless humidification module are independent of each other, the dehumidification process and the moisture absorption process can be carried out sequentially or simultaneously. When the indoor humidity is high, the dehumidification mode is operated, and the dehumidification mode includes the first dehumidification mode, the second dehumidification mode and the third dehumidification mode.

Specifically, in the dehumidification mode, the moisture absorption process of the waterless humidification module is that the second air supply fan 51 works to form a negative pressure, so that the outdoor humid air enters from the air inlet of the shell 1 of the waterless humidification module, passes through the second humidity regulating area 31 of the humidity regulating disk 3 and enters the second air cavity 21. When the air passes through the humidity regulating disk 3, the rotating humidity regulating disk 3 continuously absorbs the moisture in the stored air in the second humidity regulating area 31, and the humid air is converted into dry air and enters the second air cavity 21. Thereafter, it is delivered to the room through the second air supply fan 51, thereby reducing the indoor air humidity to efficiently dehumidify the indoor environment.

In the dehumidification mode, the dehumidification process of the waterless humidification module is as follows: after the humidity regulating disk 3 is saturated with moisture, the first blower 52 runs to form a negative pressure, and the outdoor air enters from the air inlet of the shell 1 of the waterless humidification module, and is heated by the first heating element 102 to form hot air, and then enters the first air cavity 22 through the first humidity regulating area 32 of the humidity regulating disk 3. When the air passes through the rotating humidity regulating disk 3, the water originally absorbed and collected by the hot air evaporates into water vapor, and the hot air carries the water vapor and is converted into warm and humid air, which is discharged from the shell 1 of the waterless humidification module through the first air cavity 22 and the first blower 52, thereby effectively dehumidifying the humidity regulating disk 3 of the waterless humidification module and improving the dehumidification and regeneration capacity of the humidity regulating disk 3.

Specifically, the first dehumidification mode is a dehumidification process and a moisture absorption process that are sequentially operated. Specifically, when the first dehumidification mode is operated, the moisture absorption process is performed first, and after the moisture in the humidity regulating disk 3 is saturated after a preset time, the dehumidification process is operated until the indoor air humidity is higher than the preset value again, and the aforementioned steps are repeated.

The second dehumidification mode is that the moisture absorption process is performed periodically and in stages, and the dehumidification process is performed continuously. Specifically, during the uninterrupted execution of the dehumidification process, when the indoor humidity is higher than the preset value, the moisture absorption process is run, and after the preset time, the moisture in the humidity regulating disk 3 is saturated, and the dehumidification process is performed until the indoor humidity is higher than the preset value again, and the above steps are repeated.

The third dehumidification mode is that the moisture absorption process and the dehumidification process are operated uninterruptedly. The dehumidification process can continuously discharge the moisture in the humidity conditioning plate 3. The moisture in the air is absorbed by the humidity control plate 3 during the dehumidification process. It can be understood that the specific selection of the dehumidification mode can be selected according to the outdoor humidity and the indoor humidity.

Optionally, the humidification mode of the waterless humidification module includes a moisture absorption process and a humidification process. The moisture absorption process turns on the first blower 52, and the humidification process turns on the second heating element 101 and the second blower 51.

Since the air flow paths of the humidification process and the moisture absorption process of the waterless humidification module are independent of each other, the humidification process and the moisture absorption process can be performed sequentially or simultaneously. When the indoor humidity is low, the humidification mode is operated, and the humidification mode includes a first humidification mode, a second humidification mode and a third humidification mode. Optionally, the heating component is located above the humidification zone to increase the temperature of the humidification zone.

Specifically, in the humidification mode, the moisture absorption process of the waterless humidification module is that the first air supply fan 52 works to form a negative pressure, so that the outdoor humid air enters from the air inlet of the shell 1 of the waterless humidification module, passes through the first humidity control area 32 of the humidity control disk 3 and enters the first air cavity 22. When the air passes through the humidity control disk 3, the rotating humidity control disk 3 continuously absorbs the moisture in the stored air in the first humidity control area 32, and the humid air is converted into dry air and enters the first air cavity 22, and then is sent to the outside of the shell 1 of the waterless humidification module through the first air supply fan 52.

In the humidification mode, the humidification process of the waterless humidification module is as follows: after the humidity regulating disk 3 is saturated with moisture, the second blower 51 runs to form a negative pressure, and the outdoor air enters from the air inlet of the shell 1 of the waterless humidification module, and the air is heated by the second heating element 101 to form hot air, and then enters the second air cavity 21 through the second humidity regulating area 31 of the humidity regulating disk 3. When the air passes through the rotating humidity regulating disk 3, the hot air evaporates into water vapor through the water originally absorbed and collected by the hot air, and the hot air carries the water vapor and is converted into warm and humid air, which is delivered to the room through the second air cavity 21 and the second blower 51 to deliver warm and humid air to the room.

The first humidification mode is a sequential cycle of humidification and moisture absorption. Specifically, when the first humidification mode is run, the moisture absorption process is performed first, and after a preset time, the moisture in the humidity regulating disk 3 is saturated, and the humidification process is run until the indoor air humidity is lower than the preset value again, and the above steps are repeated.

The second humidification mode is that the moisture absorption process is performed periodically and in stages, and the humidification process is performed continuously. Specifically, during the continuous execution of the humidification process, when the indoor humidity is lower than the preset value, the moisture absorption process is performed, and after the preset time, the moisture in the humidity regulating disk 3 is saturated, and the moisture absorption process is stopped until the indoor humidity is lower than the preset value again, and the above steps are repeated.

The third humidification mode is that the moisture absorption process and the humidification process are run uninterruptedly. The moisture absorption process can continuously provide moisture to the humidity regulating disk 3, so that the humidification process can continuously output warm and humid air. It can be understood that the specific selection of the humidification mode can be selected according to the outdoor humidity and the indoor humidity.

Optionally, the humidity control plate 3 includes a rotating wheel 33 and a humidity control plate 34. The rotating wheel 33 is rotatably arranged on the air inlet of the wind box 2; the humidity control plate 34 is embedded in the rotating wheel 33, and the humidity control plate 34 is used to absorb moisture in the air. The rotating wheel 33 rotates to drive the humidity control plate 34 to rotate.

Optionally, the waterless humidification module further includes a first driving device 6 and a driving gear 7. The main body of the first driving device 6 The driving gear 7 is connected to the driving output end of the first driving device 6; wherein the outer periphery of the rotating wheel 33 is provided with gear teeth, and the gear teeth mesh with the driving gear 7 for transmission.

The first driving device 6 includes a stepper motor, which drives the driving gear 7 to rotate, thereby driving the rotating wheel 33 meshing with the driving gear 7 to rotate, and the rotating wheel 33 rotates to drive the humidity control plate 34 to rotate, and the humidity control plate 34 rotates so that each position of the humidity control plate 34 can rotate to the first humidity control area 32 and the second humidity control area 31. In this way, during the moisture absorption process, the humidity control plate 34 rotates, so that the water vapor can be collected more evenly to reach the saturation state; during the dehumidification process, the humidity control plate 34 rotates, so that the water vapor at each position of the humidity control plate 34 can pass through the second humidity control area 31, thereby obtaining a better dehumidification effect.

Optionally, a circular track is formed at the air inlet of the bellows 2, and a slide rail is provided at the bottom of the rotating wheel 33, and the slide rail slides within the circular track in a limited position.

Specifically, the air inlet of the bellows 2 is a circular air outlet, the edge of the circular air outlet is provided with a groove to form a circular track, the bottom of the rotating wheel 33 is provided with a circular convex rib to form a slide rail, and the slide rail is located in the circular track. The driving gear 7 rotates, driving the rotating wheel 33 to perform circumferential rotation in the circular track, so that the humidity regulating plate 34 can rotate on the bellows 2 more stably.

Optionally, the partition 4 includes a bearing column 41, a first partition 42 and a second partition 43. The bearing column 41 is fixedly arranged in the wind box 2, and the top of the bearing column 41 is located at the center of the circular track; the first partition 42 extends from the bearing column 41 to the first inner wall surface of the wind box 2; the second partition 43 extends from the bearing column 41 to the second inner wall surface of the wind box 2, and the second inner wall surface and the first inner wall surface are arranged oppositely; wherein, the area ratio of the second humidity adjustment area 31 to the first humidity adjustment area 32 is N, N∈(1,3).

The partition 4 divides the area of the humidity regulating plate 34 into two fan-shaped areas, namely the first humidity regulating area 32 and the second humidity regulating area 31. The fan-shaped angle ratio of the first humidity regulating area 32 is greater than the fan-shaped angle ratio of the second humidity regulating area 31, so that the moisture absorption process can absorb more water vapor, so that the waterless humidification module can continue to dehumidify.
