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 by the embodiment of the present disclosure includes a housing 1, a bellows 2, a humidity control disc 3, a heating component and a first blower 51. The housing 1 is provided with an air inlet; the bellows 2 is located in the housing 1, and a wind cavity is arranged in the bellows 2. The bellows 2 is provided with a damper 23, and the damper 23 is used to open or close the wind cavity; the humidity control disc 3 is rotatably arranged at the air inlet of the bellows 2, and the humidity control disc 3 is used to absorb moisture in the air; the heating component is located in the housing 1, and the heating component is used to preheat the air, so that the heated outdoor air passes through the humidity control disc 3 and is converted into warm and humid air; the air inlet of the first blower 51 is fixed to the first air outlet of the bellows 2, and the air outlet of the first blower 51 is connected to the indoor unit of the air conditioner through the air supply pipe 13.

In the related art, fresh air passes through a waterless humidification module, which collects water vapor, resulting in a larger air supply resistance of the waterless humidification module, a lower air supply efficiency, and a smaller fresh air volume. In addition, after the fresh air passes through the waterless humidification module, it becomes dry. When the fresh air function is used in winter, the indoor humidity is low, which exacerbates the indoor dryness and worsens the user experience.

The present application sets a damper 23 on the wind box 2, thereby adding a fresh air flow path, so that the fresh air can selectively pass through the waterless humidification module, thereby meeting the demand for large air volume warm and humid air flow. In addition, by setting a rotatable humidity regulating disk 3, the moisture absorption capacity of the humidity regulating disk 3 can be improved, and the water storage capacity of the humidity regulating disk 3 is improved, thereby obtaining a better humidification effect.

Specifically, during the humidification process, the damper 23 is opened, and the first blower 51 works to form a negative pressure. A part of the air in the shell 1 is heated by the heating component to form hot air. The hot air passes through the rotating humidity regulating disk 3 and is converted into warm and humid air and enters the wind cavity. The other part of the air directly enters the wind cavity through the damper 23. After mixing, it is sent to the room through the first blower 51 to provide a large amount of warm and humid air, which solves the problem of small air 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 air cavity through the humidity regulating disk 3 and be delivered to the room through the first 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 air cavity through the humidity regulating disk 3, while the other part of the air flow directly enters the air cavity through the damper 23, thereby increasing the fresh air volume while humidifying, thereby meeting the different needs of users.

Optionally, the waterless humidification module further includes a second blower 52 and a partition 4. The air inlet of the second blower 52 is fixed to the second air outlet of the bellows 2, and the air outlet of the second blower 52 is fixed to the air outlet of the housing 1; the partition 4 is fixed in the bellows 2 to separate the air cavity in the bellows 2 into a humidifying air cavity 21 and a hygroscopic air cavity 22, the first blower 51 is connected to the humidifying air cavity 21, and the second blower 52 is connected to the hygroscopic air cavity 22; wherein the partition 4 separates the air inlet of the bellows 2 into a humidifying zone 31 and a hygroscopic zone 32, the humidifying zone 31 corresponds to the humidifying air cavity 21, the hygroscopic zone 32 corresponds to the hygroscopic air cavity 22, and the humidifying zone 31 corresponds to the humidifying air cavity 21.

Specifically, during the moisture absorption process, the second blower 52 rotates to form negative pressure, so that outdoor humid air enters from the air inlet of the shell 1 of the waterless humidification module, passes through the humidity regulating disk 3 in the moisture absorption area 32 and enters the moisture absorption air cavity 22. When the air passes through the humidity regulating disk 3, the rotating humidity regulating disk 3 continuously absorbs and stores moisture in the air in the moisture absorption area 32, and the humid air is converted into dry air and enters the moisture absorption air cavity 22, and then is discharged from the shell 1 through the second blower 52.

During the humidification process, the first blower 51 rotates to form negative pressure, and the humidity regulating plate 3 that is saturated with water vapor rotates during the moisture absorption process. A part of the outdoor air enters from the air inlet of the shell 1 of the waterless humidification module, and is heated by the heating component to form hot air. Then, it enters the humidification air chamber 21 through the humidity regulating plate 3 of the humidification area 31. When the air passes through the humidity regulating plate 3, the hot air evaporates the water originally collected by moisture absorption into water vapor, and the hot air carries the water vapor and is converted into warm and humid air before entering the humidification air chamber 21; another part of the outdoor air enters from the air inlet of the shell 1 of the waterless humidification module, and directly enters the humidification air chamber 21 through the damper 23, and is mixed with the warm and humid air. The mixed warm and humid air with a large air volume is transported to the indoor unit of the air conditioner through the second blower 52 and the air supply pipe to transport the warm and humid air to the room. Optionally, the damper 23 is located on the side of the humidification air chamber 21.

Optionally, the second blower 52 is turned on during the moisture absorption process of the waterless humidification module; and the heating component, the first blower 51 and/or the damper 23 are turned on during the humidification process of the waterless humidification module.

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 carried out sequentially or simultaneously. When the indoor humidity is low, the humidification mode is operated, and the humidification mode includes the first humidification mode, the second humidification mode and the third humidification mode.

Specifically, the first humidification mode is a humidification process and a moisture absorption process that are sequentially operated. Specifically, when the first humidification mode is operated, 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 operated until the indoor air humidity is lower than the preset value again, and the aforementioned 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 run, 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 temperature 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 is fixed on the bellows 2; 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 are meshed 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 regulating plate 34 to rotate, and the humidity regulating plate 34 rotates so that each position of the humidity regulating plate 34 can rotate to the moisture absorption area 32 and the humidification area 31. In this way, during the moisture absorption process, the humidity regulating plate 34 rotates, so that the water vapor can be collected more evenly to reach the saturation state; during the humidification process, the humidity regulating plate 34 rotates, so that the water vapor at each position of the humidity regulating plate 34 can pass through the humidification area 31, thereby obtaining a better humidification 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.

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 bellows 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 bellows 2; the second partition 43 extends from the bearing column 41 to the second inner wall surface of the bellows 2, and the second inner wall surface and the first inner wall surface are arranged oppositely; wherein the partition 4 divides the air inlet of the bellows 2 into a humidification zone 31 and a moisture absorption zone 32, and the area ratio of the moisture absorption zone 32 to the humidification zone 31 is N, N∈(1,3).

The partition 4 divides the area of the humidifying plate 34 into two fan-shaped areas, namely the humidifying area 31 and the hygroscopic area 32. The fan-shaped angle ratio of the hygroscopic area 32 is greater than the fan-shaped angle ratio of the humidifying area 31, so that more water vapor can be accumulated for the humidification process, so that the waterless humidification module can continue to humidify. Optionally, the area ratio of the hygroscopic area 32 to the humidifying area 31 can be 1.2, 1.4, 1.5, 1.8, 2, 2.5, etc. Preferably, the area ratio of the hygroscopic area 32 to the humidifying area 31 is 2, that is, the fan-shaped angle occupied by the hygroscopic area 32 is 240°, and the fan-shaped angle occupied by the humidifying area 31 is 120°.

Optionally, the bearing column 41 further includes a support beam, and the rotating wheel 33 includes a rotating shaft, which is sleeved on the support beam. On the one hand, the bearing column 41 provides a certain bearing capacity for the humidity conditioning disc 3, and on the other hand, the support beam serves as the pile core of the rotating wheel 33, which can prevent the rotating wheel 33 from deviating from the rotation center during the circumferential rotation.

Optionally, the waterless humidification module further includes a bracket 8, which is fixed on the upper part of the rotating wheel 33 to limit and fix the humidity control plate 34. It can be understood that the bracket 8 can be a cross or a cross, as long as the humidity control plate 34 can be fixed in the rotating wheel 33, so as to prevent the humidity control plate 34 from being thrown out of the rotating wheel 33 during rotation, affecting the stability of the equipment operation, or causing relative displacement with the rotating wheel 33 to generate noise and other problems.

Optionally, the waterless humidification module also includes a cap 9, which is covered above the humidification area 31, and the heating component is fixed in the heating area enclosed by the cap 9 and the humidity regulating disk 3; an air intake port 92 is opened on the side of the cap 9, and the air in the shell 1 enters the heating area through the air intake port 92, and is converted into warm and humid air and then sucked into the blower.

Specifically, the cap 9 includes a first cover plate 91 and a second cover plate formed in one piece. The first cover plate 91 is located in the moisture absorption area. 32, the first cover plate 91 includes an air inlet grille, the second cover plate is located above the humidification zone 31, and the second cover plate extends upward relative to the first cover plate 91 to form a heating space with the humidification plate 34.
