Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a waterless humidifying device and an air conditioner. Background Art

[0002] Air conditioners are widely used to regulate ambient temperature and humidity. In order to increase the ambient humidity during use, the air conditioners provided by the related art are usually equipped with a humidifier. However, traditional humidifiers require manual water addition, which is inconvenient to use. In addition, the related art provides a waterless humidifier, which can transport water vapor in the outdoor air into the room, thereby achieving the purpose of increasing the indoor humidity.

[0003] However, the waterless humidification device provided by the related art occupies a large space, makes a lot of noise, and provides a poor user experience. Summary of the Invention

[0004] The problem solved by the present invention is to save the space occupied by the waterless humidification device, reduce the noise generated during operation, and improve the user experience.

[0005] In order to solve the above problems, the present invention provides a waterless humidifying device, comprising:

[0006] The shell is provided with a fan and an air duct, and a partition structure is provided in the air duct;

[0007] The hygroscopic rotor is rotatably arranged in the shell; wherein the fan is used to blow air to the hygroscopic rotor through the air duct, and the separation structure can make a part of the air flowing through the air duct blow to the adsorption area of ​​the hygroscopic rotor that can absorb water vapor, and make the other part of the air blow to the desorption area of ​​the hygroscopic rotor that can remove the absorbed water vapor.

[0008] Due to the action of the separation structure, part of the air blown out by the fan is blown to the adsorption area of ​​the hygroscopic wheel so that the adsorption area can absorb moisture in the air, and the other part is blown to the desorption area of ​​the hygroscopic wheel to remove the moisture absorbed by the hygroscopic wheel. Therefore, only one fan is needed to meet the water absorption and dehydration needs of the hygroscopic wheel, reducing the number of fans, reducing the overall volume of the waterless humidification device, and reducing the noise generated due to the reduction in the number of fans, thereby improving user experience.

[0009] In an optional embodiment, the fan includes blades, which are rotatably disposed in the housing; wherein the rotation plane of the moisture absorbing wheel is perpendicular to or forms an acute angle with the rotation plane of the blades.

[0010] Configuring the rotation plane of the moisture absorption wheel to be perpendicular to or at an acute angle to the rotation plane of the fan blade can save space occupied by the waterless humidification device in the extension direction of the rotation axis of the fan blade, thereby ensuring the miniaturization design of the overall structure of the waterless humidification device.

[0011] In an optional embodiment, the shell includes a volute and a wheel shell, and the first end face of the wheel shell is connected to the volute; wherein the hygroscopic wheel is rotatably arranged in the wheel shell, and the fan blade is arranged in the volute; the end face of the volute is perpendicular to or at an acute angle to the first end face.

[0012] Configuring the end face of the volute and the first end face to be perpendicular or at an acute angle can further ensure a compact structural arrangement of the shell, thereby ensuring a miniaturized design of the overall structure of the waterless humidification device.

[0013] In an optional embodiment, the volute includes a first volute and a second volute that are interlocked; the impeller housing includes a first cover and a second cover that are interlocked, the first cover has a first end face, and the first end face is connected to at least one of the first volute and the second volute, and at least one of the second end face and the first end face of the second cover is perpendicular or at an acute angle to the end face of the volute.

[0014] By optimizing the structure of the impeller housing so that at least one of the first end face of the first cover and the second end face of the second cover is perpendicular to or at an acute angle to the end face of the volute, a compact structural design of the housing can be ensured; in particular, when the first end face of the first cover and the second end face of the second cover are both perpendicular to or at an acute angle to the end face of the volute, the compact structural design of the housing can be fully ensured, thereby ensuring that the overall structure of the waterless humidification device is smaller and more compact, effectively saving occupied space.

[0015] In an optional embodiment, the first cover is integrally formed with at least one of the first volute and the second volute.

[0016] In an optional embodiment, the first cover includes a first cover body and a second cover body, the first cover body is connected to the first volute, and the second cover body is connected to the second volute; wherein, at least one of the connection method between the first cover body and the first volute, and the connection method between the second cover body and the second volute are integrally formed.

[0017] Through the integrated setting, the setting of connectors and connecting parts can be reduced to further ensure the miniaturization and compact design of the shell, thereby ensuring the miniaturization design of the waterless humidification device and effectively saving the space occupied by the waterless humidification device.

[0018] Moreover, the first cover body and the second cover body are connected to the first volute and the second volute respectively. When the first volute and the second volute are buckled and connected, the first cover body and the second cover body are spliced ​​together to form the first cover, which also ensures the easy assembly of the waterless humidification device.

[0019] In an optional embodiment, the waterless humidification device further includes a heater, which is disposed in the housing; a portion of the air blown out by the fan can be blown toward the heater, and the air heated by the heater flows toward the desorption zone.

[0020] By setting up the heater, a part of the air provided by the fan can be reliably heated and the heated air can flow to the desorption area of ​​the hygroscopic wheel, and then the hot air can be used to remove the water vapor absorbed in the hygroscopic wheel, thereby achieving the purpose of increasing the ambient humidity.

[0021] In an optional embodiment, the shell is provided with a first area and a second area, both of which are connected to the air duct, the first area is opposite to the adsorption area; the second area is opposite to the desorption area; wherein the area of ​​the first area is larger than the area of ​​the second area.

[0022] In this way, the area of ​​the adsorption zone of the hygroscopic wheel can be configured to be larger than the area of ​​its desorption zone, which can ensure the moisture absorption capacity of the hygroscopic wheel, and then ensure the humidification capacity of the waterless humidification device, ensuring a good user experience.

[0023] In an optional embodiment, the shell is provided with a first exhaust hole and a second exhaust hole; the first exhaust hole is connected to the first area and is used to discharge the air that absorbs water vapor in the adsorption area; the second exhaust hole is connected to the second area and is used to discharge water vapor desorbed from the desorption area.

[0024] The air that has absorbed water vapor in the adsorption area and the water vapor desorbed from the desorption area are discharged by using the first exhaust hole and the second exhaust hole respectively. The dry air that has absorbed water vapor and the wet air mixed with water vapor can be transported to different spaces respectively. Among them, the dry air that has absorbed water vapor can be discharged to the outdoors, and the wet air mixed with water vapor can be transported indoors, thereby ensuring the reliability of the waterless humidification device for environmental humidification and ensuring user experience.

[0025] In an optional embodiment, the shell includes a first partition and a second partition, and the first partition and the second partition are both arranged on the impeller shell of the shell, and the length extension direction of the first partition and the length extension direction of the second partition are arranged at an angle to divide the impeller shell into a first area and a second area.

[0026] The first partition and the second partition are used to reliably divide the first area and the second area, so as to ensure that the adsorption area and the desorption area of ​​the moisture absorption wheel can reliably absorb and dehydrate water respectively, thereby ensuring that the waterless humidification device has a good humidification effect.

[0027] In an optional embodiment, the housing further includes an air collecting housing, the volute of the housing is connected to and communicates with the air collecting housing, and the impeller housing is connected to the volute; the impeller housing is provided with a first exhaust hole and a second exhaust hole.

[0028] Such a setting makes the waterless humidification device more integrated, which is convenient for assembling the waterless humidification device as a whole on the air conditioner for use, ensuring user experience; moreover, the first exhaust hole and the second exhaust hole are arranged on the rotor shell, which can ensure that the dry air that absorbs water vapor through the adsorption area of ​​the hygroscopic rotor and the water vapor desorbed from the desorption area of ​​the hygroscopic rotor can be reliably output to the outdoors and indoors respectively, thereby ensuring a good humidification effect of the waterless humidification device.

[0029] In an optional embodiment, the end surface of the volute is connected to and communicates with the wind collecting casing.

[0030] Due to the reduction in the number of fans, the overall volume of the waterless humidification device can be reduced. Even if the wind collecting housing is connected to the end face of the volute, the space occupied by the waterless humidification device can be saved, and the space can be fully utilized to increase the air volume, thereby increasing the amount of air flowing to the adsorption area of ​​the hygroscopic rotor, increasing the water absorption capacity of the hygroscopic rotor, improving the humidification capacity of the waterless humidification device, and ensuring user experience.

[0031] In an optional embodiment, the waterless humidification device further includes a filter, the air collecting shell is provided with an air inlet, the filter is arranged in the air collecting shell, and the filter is used to filter the air entering the air collecting shell from the air inlet before entering the volute.

[0032] A filter is set in the wind collecting shell, so that the outdoor air can be filtered by the filter and then flow to the moisture absorption wheel under the drive of the fan blades. It can also increase the ambient humidity while improving the oxygen content and cleanliness of the environment by using a waterless humidification device.

[0033] The present invention also provides an air conditioner, comprising a base and a waterless humidifying device according to any one of the aforementioned embodiments, wherein the waterless humidifying device is arranged on the base and is arranged at one end of the base along the length extension direction of the base.

[0034] The provision of a waterless humidifying device can increase the humidity of the environment when the air conditioner is used, thereby improving the user experience; moreover, the space occupied by the overall structure of the waterless humidifying device is reduced, saving the assembly space of the waterless humidifying device, which is conducive to the overall compact and miniaturized design of the air conditioner; moreover, providing the waterless humidifying device at one end in the length extension direction of the base can make the overall structure of the air conditioner more neat and compact.

[0035] In an optional embodiment, the moisture absorption wheel is distributed above or below the fan.

[0036] Placing the moisture absorbing wheel above or below the fan blades can avoid increasing the front or rear dimensions of the waterless humidifying device, thereby ensuring that the front and rear dimensions of the air conditioner are compact, making the air conditioner more beautiful.

DETAILED DESCRIPTION

[0047] Air conditioners can be used for cooling or heating. When using air conditioners for heating, the environment often becomes dry, resulting in a poor user experience. To improve the problem of air drying when the air conditioner is used for heating, the air conditioner in the related art is equipped with a humidifier. However, traditional humidifiers require manual water addition, which is inconvenient to use. In order to solve the problem of inconvenient water addition to the humidifier, the related art provides a waterless humidifier. The waterless humidifier can bring water vapor from the outdoor air into the room, thereby better maintaining the indoor humidity during heating, improving the problem of dry air, and does not require manual water addition, making it more convenient to use. The waterless humidifier includes a moisture-absorbing wheel, which can absorb water vapor from the outdoor air and remove the water vapor it absorbs from the room.

[0048] However, the waterless humidification device provided by the related art occupies a large space, which is not conducive to the miniaturization design of the air conditioner, and is noisy when used, resulting in a poor user experience.

[0049] The waterless humidifying device of this embodiment can be used in an air conditioner, and it can save space, reduce noise generated during operation, and improve user experience.

[0050] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0051] Please refer to Figure 1 This embodiment provides an air conditioner 010, which is an indoor wall mounted air conditioner. Of course, in other embodiments, the air conditioner 010 may also be a floor mounted air conditioner. The following description will take an indoor wall mounted air conditioner as an example.

[0052] The air conditioner 010 includes a base 100, a heat exchanger (not shown) and an air outlet assembly (not shown). The heat exchanger is arranged on the base 100 for exchanging heat with the air; the air outlet assembly is arranged on the base 100 for blowing out the air after heat exchange by the heat exchanger, thereby achieving the regulation of the ambient temperature.

[0053] Air conditioner 010 also includes a waterless humidifier 200, which is mounted on base 100 and located at one end of the base 100's longitudinal extension. This device draws in cool, damp outdoor air, converts it into moist, warm air, and blows it into the room, thereby increasing the indoor humidity. Placing the device 200 at one end of the base 100's longitudinal extension makes the overall structure of air conditioner 010 more compact and neat.

[0054] It should be noted that disposing the waterless humidifying device 200 in the indoor unit can facilitate the maintenance of the waterless humidifying device 200 , extend the service life of the waterless humidifying device 200 , and thus improve the user experience.

[0055] Please refer to Figure 2 The waterless humidifying device 200 includes a shell 220 and a moisture absorbing rotor 240. The shell 220 is provided with a fan 210 and an air duct 223. A partition structure is provided in the air duct 223. The moisture absorbing rotor 240 is rotatably arranged in the shell 220. The fan 210 is used to blow air to the moisture absorbing rotor 240 through the air duct 223, and the partition structure can make a part of the air flowing through the air duct 223 blow to the adsorption area of ​​the moisture absorbing rotor 240 that can absorb water vapor, and make the other part of the air blow to the desorption area of ​​the moisture absorbing rotor 240 that can remove the absorbed water vapor. In this way, when outdoor air is introduced into the waterless humidification device 200 by the fan 210, the fan 210 can blow part of the air to the adsorption area of ​​the hygroscopic wheel 240, so that the water vapor in this part of the air is adsorbed by the hygroscopic wheel 240; at the same time, the fan 210 can also blow another part of the air to the desorption area of ​​the hygroscopic wheel 240, so that the water vapor absorbed in the hygroscopic wheel 240 is desorbed and flows into the room, thereby achieving humidification of the indoor ambient air. Due to the action of the separation structure, part of the air blown out by the fan 210 is blown to the adsorption area of ​​the hygroscopic wheel 240 so that the adsorption area can absorb moisture in the air, and the other part is blown to the desorption area of ​​the hygroscopic wheel 240 to remove the moisture absorbed by the hygroscopic wheel 240. Therefore, only one fan 210 is needed to meet the water absorption and dehydration needs of the hygroscopic wheel 240, thereby reducing the number of fans, reducing the overall volume of the waterless humidification device 200, and reducing the noise generated due to the reduction in the number of fans 210, thereby improving the user experience.

[0056] Furthermore, the fan 210 includes a fan blade 230 and a first motor (not shown in the figure). The fan blade 230 is rotatably arranged in the shell 220. The first motor is assembled in the shell 220 and is transmission-connected to the fan blade 230 for driving the fan blade 230 to rotate, thereby introducing air into the waterless humidification device 200, and allowing the air to flow through the air duct 223 and blow toward the moisture-absorbing wheel 240, and then output from the waterless humidification device 200.

[0057] Please continue to refer to Figure 2The waterless humidifier 200 further includes a heater 250 disposed within the housing 220. A portion of the air blown by the fan 210 is directed toward the heater 250, causing the heated air to flow toward the desorption zone. The heater 250 includes, but is not limited to, a mica sheet electric heater or a ceramic electric heater. The heater 250 reliably heats a portion of the air provided by the fan blades 230 and directs the heated air toward the desorption zone of the moisture absorbing rotor 240. The heated air then evaporates the water vapor absorbed by the moisture absorbing rotor 240, causing the air to escape from the moisture absorbing rotor 240 and flow into the room, thereby increasing the ambient humidity.

[0058] It should be noted that the adsorption zone and desorption zone of the moisture absorption wheel 240 are divided based on their functions. The adsorption zone refers to the area of ​​the moisture absorption wheel 240 that absorbs water vapor from the air, while the desorption zone refers to the area where the moisture absorption wheel 240 uses hot air to remove the water vapor absorbed by the moisture absorption wheel 240. The moisture absorption wheel 240 is rotatably mounted on the housing 220, so that the adsorption zone and desorption zone of the moisture absorption wheel 240 can continuously alternate. Specifically, when a portion of the moisture absorption wheel 240 rotates to the area where the fan blades 230 directly blow air toward the moisture absorption wheel 240, it becomes the adsorption zone. At the same time, another portion of the moisture absorption wheel 240 is located in the area that absorbs air heated by the heater 250, which becomes the desorption zone. As the moisture absorption wheel 240 rotates, the portion previously in the adsorption zone moves to the desorption zone, and the portion previously in the desorption zone moves to the adsorption zone.

[0059] It should also be noted that the moisture absorbing wheel 240 is made of a moisture absorbing material such as molecular sieve or silica gel, which has the characteristics of absorbing moisture in the air and evaporating the water molecules in the moisture absorbing wheel 240 into high-temperature and high-humidity gas after heating.

[0060] Please continue to refer to Figure 2 In order to divide the air delivered by the fan 210 into two paths, one path flows directly to the adsorption area of ​​the hygroscopic wheel 240, and the other path flows to the heater 250 for heating and then flows to the hygroscopic wheel 240, the separation structure of this embodiment includes a guide plate 222, which is connected to the shell 220 and is located in the air duct 223. The guide plate 222 is used to divide the air delivered by the fan 210 into two paths.

[0061] In order to further save space for the waterless humidification device 200, please refer to Figure 2 The rotation plane of the moisture absorption wheel 240 is configured to be perpendicular to the rotation plane of the fan blades 230. This configuration can save space occupied by the waterless humidification device 200 in the extension direction of the rotation axis of the fan blades 230, thereby ensuring a miniaturized design of the overall structure of the waterless humidification device 200.

[0062] It should be understood that in other embodiments, the rotation plane of the moisture-absorbing rotor 240 is configured to form an acute angle with the rotation plane of the fan blades 230. Specific angles include, but are not limited to, 88°, 85°, etc., and are not specifically limited herein. This configuration can save space occupied by the waterless humidification device 200 in the direction of the rotation axis of the fan blades 230, thereby ensuring a compact design of the overall structure of the waterless humidification device 200.

[0063] Please refer to Figure 2 The shell 220 is provided with an air outlet 221, the air outlet 221 is connected to the air duct 223, and one end face of the hygroscopic wheel 240 is distributed opposite to the air outlet 221; the air outlet 221 of the shell 220 is configured to be distributed opposite to the end face of the hygroscopic wheel 240, so that the air provided by the fan blades 230 can reliably flow to the hygroscopic wheel 240, reduce the loss of air volume, ensure the air volume, and then ensure the reliability of the hygroscopic wheel 240 in absorbing water vapor in the air, ensure the humidification amount of the waterless humidification device 200, and improve the user experience.

[0064] Furthermore, the air outlet 221 is opposite to the adsorption zone of the moisture absorption wheel 240. Configuring the air outlet 221 opposite to the adsorption zone of the moisture absorption wheel 240 ensures that a portion of the air delivered by the fan blades 230 flows directly to the adsorption zone of the moisture absorption wheel 240. This ensures that the air volume flowing to the adsorption zone is sufficient, reducing air volume loss, thereby reliably absorbing water vapor in the air, ensuring the moisture absorption capacity of the moisture absorption wheel 240, and thus ensuring sufficient humidification.

[0065] Please refer to Figure 3 and Figure 4 The housing 220 includes a volute 260, an air collecting housing 270, and a rotor housing 280. The volute 260 is connected and communicates with the air collecting housing 270, and the rotor housing 280 is connected to the volute 260. The air duct 223 connects the rotor housing and the volute. The fan blades 230 are rotatably disposed within the volute 260, and the moisture-absorbing rotor 240 is rotatably disposed within the rotor housing 280. This arrangement makes the waterless humidification device 200 highly integrated, facilitating its integral assembly with the air conditioner 010 for use, ensuring a superior user experience.

[0066] For further information, please refer to Figure 4The waterless humidifier 200 further includes a filter 272. The air collecting housing 270 is provided with an air inlet 271, which can be used to communicate with the outside to facilitate the introduction of outdoor air into the waterless humidifier 200. The filter 272 is provided within the air collecting housing 270 and is used to filter the air entering the air collecting housing 270 from the air inlet 271 before entering the volute 260. The filter 272 is provided within the air collecting housing 270 so that the air introduced from the outside into the air collecting housing 270 by the fan blades 230 passes through the filter 272 and then flows to the moisture absorbing rotor 240 under the drive of the fan blades 230. This allows the waterless humidifier 200 to increase the ambient humidity while improving the oxygen content and cleanliness of the environment.

[0067] It should be noted that since the rotation plane of the hygroscopic wheel 240 is configured to be perpendicular or at an acute angle to the rotation plane of the fan blade 230, the space occupied by the waterless humidification device 200 in the extension direction of the rotation axis of the fan blade 230 can be saved, and the size of the inner cavity of the volute 260 and the wind collecting shell 270 can be increased in the extension direction of the rotation axis of the fan blade 230, which is beneficial to increase the air intake of the waterless humidification device 200, and increase the amount of water vapor absorbed by the hygroscopic wheel 240 through the increase in the air intake, so as to make full use of the space to increase the humidification amount and improve the user experience.

[0068] Please refer to Figure 3 The first end face 301 of the impeller housing 280 is connected to the volute 260, and the end face of the volute 260 is perpendicular to the first end face 301 of the impeller housing 280. Of course, in other embodiments, the end face of the volute 260 and the first end face 301 of the impeller housing 280 form an acute angle. Configuring the end face of the volute 260 and the first end face 301 of the impeller housing 280 to be perpendicular or at an acute angle further ensures a compact structure of the housing 220, thereby ensuring a compact design of the overall structure of the waterless humidifier 200.

[0069] Please continue to refer to Figure 3 The end face of the volute 260 is connected to the air collecting housing 270 along the extension direction of the rotation axis of the fan blades 230. Because the rotation plane of the moisture absorption wheel 240 is configured to be perpendicular to or at an acute angle to the rotation plane of the fan blades 230, even if the air collecting housing 270 is connected to the end face of the volute 260, the space occupied by the waterless humidifier 200 in the extension direction of the rotation axis of the fan blades 230 can be saved, and the space can be fully utilized to increase the air volume and improve the humidification capacity. In addition, connecting the air collecting housing 270 to the end face of the volute 260 can ensure the air intake of the waterless humidifier 200, thereby increasing the amount of air flowing into the adsorption zone of the moisture absorption wheel 240, increasing the water absorption capacity of the moisture absorption wheel 240, improving the humidification capacity of the waterless humidifier 200, and ensuring the user experience.

[0070] Optionally, the volute 260 of this embodiment includes a volute body 261 and an air outlet housing 262. The air outlet housing 262 is connected to the volute body 261. The end surface of the volute body 261 is connected to the air collecting housing 270. The rotor housing 280 is connected to the air outlet housing 262 and communicates with the interior of the volute body 261 through the air outlet housing 262. Because the rotation plane of the moisture-absorbing rotor 240 is configured to be perpendicular to or at an acute angle to the rotation plane of the fan blades 230, even if the end surface of the volute body 261 is connected to the air collecting housing 270, the space occupied by the waterless humidifier 200 in the direction of the rotation axis of the fan blades 230 can be reduced, and the space can be fully utilized to increase the air volume and improve the humidification effect.

[0071] Furthermore, the guide plate is connected to the air outlet housing 262 and is distributed inside the air outlet housing 262, so that the air transported to the air outlet housing 262 by the fan blades 230 is divided into two paths by the guide plate, one path flows directly to the adsorption area of ​​the hygroscopic wheel 240, and the other path flows to the heater 250 and flows to the desorption area of ​​the hygroscopic wheel 240 after heating.

[0072] Please refer to Figure 3 and Figure 4 The volute 260 includes a first volute 263 and a second volute 264 that are interlocked and connected. The connection methods of the first volute 263 and the second volute 264 include, but are not limited to, snap-fitting, connecting with fasteners such as bolts, and bonding. This arrangement facilitates the assembly of the fan blade 230 into the volute 260.

[0073] The air collecting housing 270 includes a first housing 273 and a second housing 274. The first housing 273 is connected and communicates with the second volute 264. The air inlet 271 is provided in the first housing 273. The first housing 273 and the second housing 274 are snap-fitted and connected, and the filter 272 is assembled between the first housing 273 and the second housing 274. The connection methods of the first housing 273 and the second volute 264 include, but are not limited to, integral molding, snap-fitting, or connection with fasteners such as bolts. The connection methods of the first housing 273 and the second housing 274 include, but are not limited to, integral molding, snap-fitting, or connection with fasteners such as bolts. It should be understood that in other embodiments, the air inlet 271 can also be provided in the second housing 274.

[0074] It should be noted that in an embodiment where the first shell 273 and the second volute 264 are integrally formed, the structural strength of the first shell 273 and the second volute 264 is greater and less likely to be damaged by wind pressure and the like, thereby improving the air tightness of the waterless humidification device 200 and improving the user experience.

[0075] It should also be noted that the second shell 274 can be connected to the base 100 to ensure that the waterless humidification device 200 is reliably assembled on the base 100 .

[0076] Please continue to refer to Figure 3 and Figure 4 The rotor housing 280 includes a first cover 283 and a second cover 284. The first cover 283 is connected to the volute 260. Specifically, the first cover 283 has a first end surface 301, which is connected to both the first and second volutes 263 and 264. The first cover 283 and the second cover 284 are engaged and connected, and the moisture absorption rotor 240 is rotatably disposed between the first and second covers 283 and 284. The connection between the first and second covers 283 and 284 includes, but is not limited to, snap-fitting or fasteners such as bolts. This arrangement facilitates installation and removal of the moisture absorption rotor 240 from the rotor housing 280 and also facilitates maintenance of the moisture absorption rotor 240.

[0077] Of course, in other embodiments, the first end surface 301 of the first cover 283 may be connected to only one of the first volute 263 and the second volute 264 .

[0078] Furthermore, the second cover 284 has a second end surface 302, which is located opposite to the first end surface 301 of the first cover 283. The second end surface 302 and the first end surface 301 of the first cover 283 are both perpendicular to the end surface of the volute 260. Of course, in some embodiments, the second end surface 302 and the first end surface 301 of the first cover 283 may both form an acute angle with the end surface of the volute 260; in other embodiments, at least one of the second end surface 302 and the first end surface 301 of the first cover 283 is perpendicular to or forms an acute angle with the end surface of the volute 260, that is, only the first end surface 301 of the first cover 283 is perpendicular to or forms an acute angle with the end surface of the volute 260.

[0079] By optimizing the structure of the impeller housing 280 so that at least one of the first end face 301 of the first cover 283 and the second end face 302 of the second cover 284 is perpendicular to or at an acute angle to the end face of the volute 260, a compact structural design of the housing can be ensured. In particular, in this embodiment, when the first end face 301 of the first cover 283 and the second end face 302 of the second cover 284 are both perpendicular to or at an acute angle to the end face of the volute 260, a compact structural design of the housing 220 can be fully ensured, thereby ensuring that the overall structure of the waterless humidification device 200 is more compact and smaller, effectively saving occupied space.

[0080] The first cover 283 includes a first cover body 285 and a second cover body 286. The first cover body 285 is connected to the first volute 263, and the second cover body 286 is connected to the second volute 264. When the first volute 263 and the second volute 264 are snap-fitted and connected, the first cover body 285 and the second cover body 286 are assembled to form the first cover 283, ensuring easy assembly of the waterless humidifier. The connection methods of the first cover body 285 to the first volute 263 and the second cover body 286 to the second volute 264 include, but are not limited to, integral molding, snap-fitting, or fasteners such as bolts. In embodiments where the first cover body 285 is integrally formed with the first volute 263 and the second cover body 286 is integrally formed with the second volute 264, this integrated arrangement can reduce the number of connectors and connecting parts, further ensuring a miniaturized and compact design of the housing 220, and thus ensuring a miniaturized design of the waterless humidifier 200, effectively saving space occupied by the waterless humidifier 200.

[0081] It should be understood that in other embodiments, the first cover 283 may be integrally formed, that is, rather than being formed by splicing the first cover body 285 and the second cover body 286, the first cover 283 may be integrally formed with either the first volute 263 or the second volute 264. This configuration can also reduce the number of connectors and connecting parts through an integrated configuration, thereby ensuring a compact structural design of the housing 220.

[0082] Furthermore, the second cover 284 is connected to a rotating shaft (not shown), please refer to Figure 3 and Figure 5 The waterless humidifying device 200 also includes a second motor 288, a gear 289 and a ring gear 290. The hygroscopic wheel 240 is rotatably plugged into the rotating shaft, and the ring gear 290 is connected to the outer periphery of the hygroscopic wheel 240. The second motor 288 is assembled on the second cover 284. The output shaft of the second motor 288 is transmission-connected with the gear 289, and the gear 289 is meshed with the ring gear 290 to form a reduction transmission relationship; when the output shaft of the second motor 288 drives the gear 289 to rotate, the gear 289 can drive the ring gear 290 to drive the hygroscopic wheel 240 to rotate slowly, thereby ensuring that the adsorption area of ​​the hygroscopic wheel 240 can reliably absorb more water vapor, and that the water vapor in the desorption area can be removed as much as possible, ensuring that the humidification capacity of the waterless humidifying device 200 is sufficiently large.

[0083] In this embodiment, the heater 250 is assembled on the first cover 283 and is located between the first cover 283 and the hygroscopic wheel 240; such a configuration can ensure that a portion of the air flow transported by the fan blades 230 can reliably enter the desorption zone of the hygroscopic wheel 240 after being heated by the heater 250, and then reliably use the hot air to remove the water vapor adsorbed in the hygroscopic wheel 240, thereby achieving the purpose of humidification.

[0084] The way of assembling the heater 250 to the first cover 283 includes but is not limited to connecting the heater 250 to the first cover 283 with fasteners such as bolts, or connecting a bracket to the first cover 283 and connecting the heater 250 to the bracket via fasteners.

[0085] Please refer to Figure 5 In this embodiment, the housing 220 is provided with a first area 281 and a second area 282. Both the first area 281 and the second area 282 are connected to the air duct 223. The first area 281 is opposite the adsorption area, while the second area 282 is opposite the desorption area. The area of ​​the first area 281 is larger than the area of ​​the second area 282. This ensures that the adsorption area of ​​the moisture absorption wheel 240 is larger than the desorption area, ensuring the moisture absorption capacity of the moisture absorption wheel 240, and thus the humidification capacity of the waterless humidification device 200, and ensuring a good user experience.

[0086] Furthermore, the impeller shell 280 is provided with a first area 281 and a second area 282; specifically, the shell 220 also includes a first partition 293 and a second partition 294, and the first partition 293 and the second partition 294 are both arranged on the impeller shell 280, and the length extension direction of the first partition 293 and the length extension direction of the second partition 294 are arranged at an angle to divide the impeller shell 280 into the first area 281 and the second area 282; the angle between the first partition 293 and the second partition 294 includes but is not limited to 120°, 130° or 100°.

[0087] Furthermore, the first cover 283 is connected to a first partition 293 and a second partition 294; the second cover 284 is connected to a third partition and a fourth partition (neither of which is shown in the figure), with the length of the third partition extending in a direction that forms an angle with the length of the fourth partition. The first partition 293 and the third partition are arranged opposite each other, while the second partition 294 and the fourth partition are arranged opposite each other. The first partition 293, the second partition 294, the third partition, and the fourth partition together form a zone within the rotor housing 280, forming a portion of the zone that faces the adsorption zone of the moisture absorption rotor 240 and another portion of the zone that faces the desorption zone. This arrangement ensures that the adsorption zone and the desorption zone of the moisture absorption rotor 240 can reliably absorb and dehydrate water, respectively, thereby ensuring a good humidification effect.

[0088] Please refer to Figure 6The housing 220 is provided with a first exhaust hole 291 and a second exhaust hole 292. The first exhaust hole 291 is connected to the first region 281 and is used to exhaust air that has absorbed water vapor in the adsorption region. The second exhaust hole 292 is connected to the second region 282 and is used to exhaust water vapor released from the desorption region. The first exhaust hole 291 and the second exhaust hole 292 are used to exhaust air that has absorbed water vapor in the adsorption region and water vapor released from the desorption region, respectively. Dry air that has absorbed water vapor and wet air mixed with water vapor can be transported to different spaces. The dry air that has absorbed water vapor can be discharged outdoors, while the wet air mixed with water vapor can be transported indoors. This ensures the reliability of the waterless humidification device 200 for environmental humidification and a better user experience.

[0089] Furthermore, the rotor shell 280 is provided with a first exhaust hole 291 and a second exhaust hole 292. The first exhaust hole 291 and the second exhaust hole 292 are provided in the rotor shell 280, and the first exhaust hole 291 is configured to be connected to the first area 281, and the second exhaust hole 292 is connected to the second area 282. This ensures that the dry air that has absorbed water vapor through the adsorption area of ​​the moisture absorption wheel 240 and the water vapor desorbed from the desorption area of ​​the moisture absorption wheel 240 can be transported to different spaces, wherein the dry air that has absorbed water vapor can be discharged from the first area 281 through the first exhaust hole 291 to the outside, and the wet air mixed with water vapor can be transported from the second area 282 through the second exhaust hole 292 to the inside of the room, thereby ensuring the reliability of the waterless humidification device 200 for environmental humidification and ensuring user experience.

[0090] Furthermore, the first exhaust hole 291 and the second exhaust hole 292 are both opened in the second cover 284, so that the air introduced into the waterless humidification device 200 by the fan 210 can reliably flow through the moisture absorption wheel 240 and then be discharged, thereby ensuring the air volume and humidification amount.

[0091] Please note that, please refer to Figure 7 and Figure 8 When the waterless humidifying device 200 is assembled on the base 100, the impeller housing 280 is distributed above or below the volute 260, and then the moisture absorbing impeller 240 can be distributed above or below the fan 210, that is, the moisture absorbing impeller 240 can be distributed above or below the fan blade 230; in this way, it is possible to avoid increasing the front or rear size of the waterless humidifying device 200, thereby ensuring that the front and rear dimensions of the air conditioner 010 are compact, and avoiding the air conditioner 010 from protruding too much from the wall after being assembled on the wall, making the air conditioner 010 more beautiful.

[0092] It should also be noted that the above-mentioned top, bottom, front and back are relative positions based on the air conditioner 010 after being installed on a wall or other installation location, rather than the absolute position of the air conditioner 010 itself.

[0093] The air conditioner 010 of this embodiment can be used for cooling or heating, and can also be used for humidifying the indoor space; in particular, when using the air conditioner 010 for heating, the fan 210 can also be used to introduce outdoor air into the waterless humidifying device 200, and the introduced air is filtered and divided into two paths to flow to the hygroscopic wheel 240, one of which flows directly to the adsorption area of ​​the hygroscopic wheel 240, and the other flows to the heater 250, and then flows to the desorption area of ​​the hygroscopic wheel 240 after the heater 250 heats the air; in this way, after the hygroscopic wheel 240 is used to adsorb water vapor in the outdoor air, it can be desorbed and transported to the indoor space, thereby achieving the effect of humidification, thereby improving the user experience when using the air conditioner for heating.

[0094] In summary, the waterless humidifying device 200 of the present invention can save occupied space and reduce the noise generated during operation, thereby improving the user experience of the air conditioner 010 equipped with the waterless humidifying device 200 .

[0095] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the scope defined by the claims.
