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. Related art air conditioners are equipped with waterless humidifiers to effectively increase ambient humidity during use. These devices typically include an air supply mechanism, a heater, and a moisture-absorbing rotor. The air supply mechanism blows air toward the heater for heating, which then flows through the moisture-absorbing rotor. The heated air then absorbs moisture absorbed by the rotor, generating high-temperature moisture that is then blown out, thereby humidifying the air.

[0003] However, the waterless humidification device provided by the related art is prone to damage to the moisture absorbing wheel, thereby increasing maintenance costs and providing a poor user experience. Summary of the Invention

[0004] The problem solved by the present invention is to improve the problem that the moisture absorption wheel is easily damaged, which is beneficial to reducing maintenance costs and improving user experience.

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

[0006] Air supply mechanism;

[0007] a moisture absorbing rotor, the moisture absorbing rotor being rotatably mounted on an air supply mechanism, the air supply mechanism being configured to blow a portion of air toward the moisture absorbing rotor so that the moisture absorbing rotor can absorb the moisture therein; and

[0008] A heater is provided in the air supply mechanism and is located at one end surface of the moisture absorption rotor; wherein the heater has an air inlet and an air outlet, and the air supply mechanism is used to blow another portion of air toward the heater, so that the air flows from the air inlet to the air outlet and is heated to become hot gas that can flow toward the moisture absorption rotor;

[0009] The direction from the air inlet to the air outlet is the preset direction, and the preset direction is parallel to the end face, or the preset direction is angled with the end face and extends in a direction away from the end face.

[0010] By making the preset direction of the air inlet pointing to the air outlet parallel to the end face of the hygroscopic wheel, or making the preset direction and the end face of the hygroscopic wheel distributed at an angle and extending in the direction away from the end face of the hygroscopic wheel, the problem of hot air heated by the heater and flowing to the hygroscopic wheel directly flowing to and entering the hygroscopic wheel can be improved, thereby improving the problem of the hygroscopic wheel being easily damaged due to high temperature, which is conducive to reducing maintenance costs and improving user experience.

[0011] In an optional embodiment, the heater includes a wind cover and a heater body, the heater body is arranged in the wind cover, the wind cover has an air inlet and an air outlet, and the wind cover is arranged on the air supply mechanism.

[0012] Placing the heater body in the air hood can improve the safety issues caused by the high temperature generated by the heater body, and is conducive to improving the problem that the moisture absorption wheel is easily damaged by high temperature, which is conducive to reducing maintenance costs and improving user experience.

[0013] In an optional embodiment, the wind shield is a sheet metal wind shield.

[0014] The use of sheet metal hoods can improve the problem of deformation or even burning of the hood at high temperatures caused by the high temperature of the heater body, thereby improving safety; it can also effectively improve the problem of the moisture absorption wheel being easily damaged by high temperatures.

[0015] In an optional embodiment, the wind hood includes a first side wall, a second side wall, a third side wall and a fourth side wall that are angled and connected end to end in sequence, one end of the first side wall, one end of the second side wall, one end of the third side wall and one end of the fourth side wall together form an air inlet, and the other end of the first side wall, the other end of the second side wall, the other end of the third side wall and the other end of the fourth side wall together form an air outlet; wherein, at least one of the second side wall and the fourth side wall is distributed parallel to the end face.

[0016] By making at least one of the second side wall and the fourth side wall parallel to the end face of the hygroscopic wheel, the airflow from the air inlet to the air outlet can be roughly parallel to the end face of the hygroscopic wheel, which can improve the problem of the gas heated by the heater flowing directly to the hygroscopic wheel, and further improve the problem of the hygroscopic wheel being easily damaged by high temperature, thereby reducing maintenance costs and improving user experience.

[0017] In an optional embodiment, the second side wall and the fourth side wall are both distributed parallel to the end surface, and the first side wall and the third side wall are both distributed perpendicular to the end surface.

[0018] When the second side wall and the fourth side wall are both distributed parallel to the end face of the hygroscopic wheel, the first side wall and the third side wall are both distributed perpendicular to the end face of the hygroscopic wheel, so that the wind cover can be roughly in a cubic frame structure. It can not only improve the problem of the gas heated by the heater flowing directly to the hygroscopic wheel, but also ensure the compact structural design of the heater, thereby reducing the assembly space required for the heater, ensuring the compact and miniaturized design of the waterless humidification device, and improving the user experience.

[0019] In an optional embodiment, the air supply mechanism includes a shell and a fan blade assembly, the hygroscopic wheel is rotatably disposed on the shell, the heater is disposed on the shell, and the fan blade assembly is disposed inside the shell for blowing part of the air toward the hygroscopic wheel and blowing another part of the air toward the heater.

[0020] By conveying a part of the air through the fan blade assembly to flow directly through the hygroscopic wheel, the hygroscopic wheel can be used to absorb the water vapor in the air, and conveying another part of the air through the heater through the fan blade assembly, the heated air can flow to the hygroscopic wheel, and the hot air can be used to bring out the water vapor absorbed in the hygroscopic wheel, thereby achieving the effect of increasing the humidity; since only one fan blade assembly is required, it is beneficial to reduce the cost of the waterless humidification device.

[0021] In an optional embodiment, the shell includes a volute, a base and a rotor cover, the fan blade assembly is arranged in the volute, the volute is connected to the base, the rotor cover is connected to the base, the moisture-absorbing rotor is rotatably arranged on the rotor cover and is located between the rotor cover and the base, and the heater is arranged on the base.

[0022] In this way, the heater can be reliably arranged at one end surface of the moisture absorption wheel, thereby facilitating the use of air heated by the heater to effectively bring out the water vapor absorbed in the moisture absorption wheel, thereby achieving a humidification effect.

[0023] In an optional embodiment, the shell further includes a first partition and a second partition, both of which are connected to the base, and the length extension direction of the first partition and the length extension direction of the second partition are distributed at an angle, and the first partition and the second partition divide the base into a first area and a second area, and the first area is distributed relative to the desorption area where the hygroscopic wheel can remove the water vapor absorbed by it, and the second area is distributed relative to the adsorption area where the hygroscopic wheel can absorb water vapor.

[0024] The use of partitions to divide the shell into areas can ensure that the moisture-absorbing wheel can reliably absorb water vapor and reliably remove the absorbed water vapor, thereby achieving a good humidification effect.

[0025] In an optional embodiment, the area of ​​the second region is larger than that of the first region.

[0026] By configuring the area of ​​the second region to be larger than the first region, the area of ​​the adsorption zone corresponding to the hygroscopic wheel for absorbing water vapor can be made larger than the adsorption zone for removing water vapor from the hygroscopic wheel, thereby ensuring that the hygroscopic wheel can absorb enough water vapor and ensure the humidification amount of the waterless humidification device, that is, the waterless humidification device has a good humidification effect.

[0027] In an alternative embodiment, the heater is disposed within the first region.

[0028] The heater is arranged in the first area to ensure that the air heated by the heater reliably flows to the desorption area, so that the water vapor absorbed by the moisture absorption wheel is reliably taken out by the hot air to achieve humidification.

[0029] In an optional embodiment, one end of the first partition is connected to the base, and the other end of the first partition is connected to the heater; one end of the second partition is connected to the base, and the other end of the second partition is connected to the heater.

[0030] Connecting the heater between the first partition and the second partition can ensure that the air heated by the heater can reliably flow to the desorption area of ​​the hygroscopic wheel, and then reliably utilize the heated air to convert the moisture absorbed in the hygroscopic wheel into water vapor and be taken out to achieve the humidification effect.

[0031] In an optional embodiment, the base is provided with an outlet, the outlet is communicated with the interior of the volute, and the outlet is distributed in the second area.

[0032] Setting the outlet of the base in the second area can ensure that a portion of the air transported by the fan blade assembly flows directly to the hygroscopic wheel, thereby ensuring the reliability of the hygroscopic wheel in absorbing water vapor in the air, ensuring the humidification capacity of the waterless humidification device, and helping to improve user experience.

[0033] The present invention also provides an air conditioner comprising the waterless humidifying device according to any one of the aforementioned embodiments.

[0034] Air conditioners can use waterless humidification devices for humidification to adjust the ambient humidity; waterless humidification devices can improve the problem that the moisture absorption wheel is easily damaged by high temperature, which helps to reduce maintenance costs and improve user experience.

DETAILED DESCRIPTION

[0043] Air conditioners can be used for both cooling and heating. However, heating often results in a dry environment, resulting in a poor user experience. To address this issue, conventional air conditioners are equipped with waterless humidifiers. These devices bring moisture from outdoor air into the room, effectively maintaining indoor humidity during heating and improving the dry air problem.

[0044] A waterless humidifier usually includes an air supply mechanism, a heater and a hygroscopic wheel. The hygroscopic wheel is used to absorb water vapor in the outdoor air. The air supply mechanism blows air toward the heater for heating, so that the heated air flows through the hygroscopic wheel. The water vapor absorbed by the hygroscopic wheel is blown out under the action of hot air to form high-temperature moisture, thereby achieving the purpose of humidifying the air.

[0045] However, the waterless humidification device provided by the related art is prone to damage to the moisture absorbing wheel, thereby increasing the maintenance cost of the air conditioner and providing a poor user experience.

[0046] The waterless humidifying device configured for the air conditioner of this embodiment can improve the problem that the moisture absorption wheel is easily damaged, which is beneficial to reducing the maintenance cost of the air conditioner and improving the user experience.

[0047] 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.

[0048] Please refer to Figure 1 This embodiment provides an air conditioner 010, which is an indoor wall-mounted unit. Of course, in other embodiments, the air conditioner 010 may also be a floor-standing air conditioner, or an indoor unit and an outdoor unit used in conjunction therewith. The following description will take the indoor wall-mounted unit as an example.

[0049] The air conditioner 010 includes an air conditioner base 100, a heat exchanger (not shown in the figure) and an air outlet assembly (not shown in the figure). The heat exchanger is arranged on the air conditioner base 100 and is used to exchange heat for the air; the air outlet assembly is arranged on the air conditioner base 100 and is used to blow out the air after heat exchange by the heat exchanger, thereby achieving the regulation of the ambient temperature.

[0050] The air conditioner 010 also includes a waterless humidifying device 200, which is arranged on the air conditioner base 100 and is located at one end of the length extension direction of the air conditioner base 100; the waterless humidifying device 200 can absorb the wet and cold air outdoors and convert it into wet and hot gas and blow it into the room to increase the indoor humidity.

[0051] Please refer to Figure 2-Figure 4 The waterless humidifying device 200 includes an air supply mechanism 300, a moisture absorbing wheel 400 and a heater 500. The air supply mechanism 300 is arranged on the air conditioner base 100, and the moisture absorbing wheel 400 is arranged on the air supply mechanism 300. The air supply mechanism 300 is used to blow a part of the air (outdoor air) to the moisture absorbing wheel 400 so that the moisture absorbing wheel 400 can absorb the water vapor therein; the heater 500 is arranged on the air supply mechanism 300, and the heater 500 is located at one end surface 401 of the moisture absorbing wheel 400; wherein, the heater The heater 500 has an air inlet 501 and an air outlet 502. The air supply mechanism 300 is used to blow another portion of air (outdoor air) toward the heater 500, causing the air to flow from the air inlet 501 to the air outlet 502 and be heated to become hot air that can flow to the moisture absorption wheel 400. The hot air flowing to the moisture absorption wheel 400 can evaporate the water vapor absorbed by the moisture absorption wheel 400 due to the high temperature. In other words, the water vapor absorbed by the moisture absorption wheel 400 can be carried away by the hot air, thereby achieving the purpose of humidification. In other words, the waterless humidification device 200 can use the moisture absorption wheel 400 to adsorb and then desorb water vapor in the air to achieve the purpose of humidification.

[0052] Please refer to Figure 4 The air supply mechanism 300 includes a housing 310 and a fan assembly 320. The moisture absorption wheel 400 is rotatably mounted on the housing 310, and the heater 500 is mounted on the housing 310. The fan assembly 320 is disposed within the housing 310 and is configured to blow a portion of the air toward the moisture absorption wheel 400 and another portion of the air toward the heater 500. The fan assembly 320 directs a portion of the air through the moisture absorption wheel 400, allowing the moisture absorption wheel 400 to absorb moisture in the air. The fan assembly 320 directs another portion of the air through the heater 500, allowing the heated air to flow toward the moisture absorption wheel 400. The heated air then removes the moisture absorbed by the moisture absorption wheel 400, thereby increasing the humidity. Since only one fan assembly 320 is required, the cost of the waterless humidifier 200 is reduced.

[0053] It should be noted that the hygroscopic wheel 400 can be divided into an adsorption zone and a desorption zone based on its function. The adsorption zone refers to the area of ​​the hygroscopic wheel 400 that absorbs water vapor from the air, while the desorption zone refers to the area where the hygroscopic wheel 400 uses hot air to remove the water vapor absorbed by the hygroscopic wheel 400. The hygroscopic wheel 400 is rotatably mounted on the housing 310, so that the adsorption zone and desorption zone of the hygroscopic wheel 400 can continuously alternate. Specifically, when a portion of the hygroscopic wheel 400 rotates to the area where the fan assembly 320 directly blows air toward the hygroscopic wheel 400, it becomes the adsorption zone. At the same time, another portion of the hygroscopic wheel 400 is located in the area that absorbs air heated by the heater 500, which becomes the desorption zone. As the hygroscopic wheel 400 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.

[0054] Please refer to Figure 2 and Figure 4 The structure of the housing 310 can be selected as needed. In this embodiment, the housing 310 includes a volute 311, a base 312, and a rotor cover 313. The fan assembly 320 is disposed within the volute 311, which is connected to the base 312. The rotor cover 313 is also connected to the base 312. The moisture absorption wheel 400 is rotatably disposed within the rotor cover 313 and is located between the rotor cover 313 and the base 312. The heater 500 is disposed within the base 312. This arrangement allows the heater 500 to be securely positioned at one end surface 401 of the moisture absorption wheel 400. This facilitates the use of air heated by the heater 500 to effectively remove moisture absorbed within the moisture absorption wheel 400, thereby achieving a humidification effect.

[0055] The connection method between the base 312 and the wheel cover 313 can be selected as needed, for example, by snap connection, connection with fasteners such as screws, etc., which is not specifically limited here.

[0056] The connection method between the base 312 and the volute 311 can be selected as needed, for example: integral molding, clamping, or connection with fasteners such as screws, etc., which is not specifically limited here.

[0057] In this embodiment, please refer to Figure 2 and Figure 4 The rotor cover 313 is connected to a rotating shaft 341, and the moisture absorption rotor 400 is plugged into the rotating shaft 341, so that the moisture absorption rotor 400 can rotate about the rotating shaft 341. The waterless humidification device 200 also includes a drive assembly 330. The drive assembly 330 is disposed on the rotor cover 313 and is in transmission connection with the moisture absorption rotor 400, and is used to drive the moisture absorption rotor 400 to rotate about the rotating shaft 341. This ensures that the moisture absorption rotor 400 continuously rotates, reliably absorbing and removing moisture, thereby ensuring that the waterless humidification device 200 reliably humidifies the environment.

[0058] Alternatively, see Figure 2 and Figure 3 The drive assembly 330 includes a motor 331, a gear (not shown), and a ring gear 332. The ring gear 332 is fixedly mounted on the outer periphery of the moisture absorption wheel 400. The motor 331 is mounted on the wheel cover 313. The gear is in driving connection with the output shaft of the motor 331, and the gear meshes with the ring gear 332. When the output shaft of the motor 331 drives the gear to rotate, the gear drives the ring gear 332 and the moisture absorption wheel 400 to rotate synchronously. Furthermore, the transmission between the gear and the ring gear 332 is a reduction transmission. This arrangement enables the moisture absorption wheel 400 to rotate at a relatively slow speed, thereby ensuring that the moisture absorption wheel 400 can reliably absorb water vapor from the air and reliably remove the absorbed water vapor, thereby ensuring reliable humidification. It also ensures that the drive assembly 330 has a compact structure, which is conducive to miniaturization.

[0059] Of course, in other embodiments, the output shaft of the motor 331 may be directly connected to the moisture absorption wheel 400 in a transmission manner, which is not specifically limited here.

[0060] For further information, please refer to Figure 4 The wheel cover 313 is provided with a humidification port 342, and the water vapor brought out from the moisture absorbing wheel 400 can be output through the heating port to achieve the adjustment of the ambient humidity.

[0061] Please refer to Figure 3 and Figure 5The housing 310 of this embodiment further includes a first partition 314 and a second partition 315. Both the first partition 314 and the second partition 315 are connected to the base 312. The length of the first partition 314 and the length of the second partition 315 form an angle. The first partition 314 and the second partition 315 divide the base 312 into a first area 316 and a second area 317. The heater 500 is disposed within the first area 316. The first area 316 is located opposite the desorption area of ​​the moisture absorption wheel 400, while the second area 317 is located opposite the adsorption area of ​​the moisture absorption wheel 400. The area of ​​the second area 317 is larger than that of the first area 316. The use of partitions to divide the housing 310 into zones ensures that the moisture absorption wheel 400 can reliably absorb and release water vapor, achieving a good humidification effect. By configuring the area of ​​the second region 317 to be larger than that of the first region 316, the area of ​​the adsorption zone corresponding to the hygroscopic wheel 400 for absorbing water vapor can be larger than the adsorption zone for removing water vapor from the hygroscopic wheel 400, thereby ensuring that the hygroscopic wheel 400 can absorb enough water vapor and ensure the humidification capacity of the waterless humidifying device 200, that is, the waterless humidifying device 200 has a good humidification effect; moreover, arranging the heater 500 in the first region 316 can ensure that the air heated by the heater 500 reliably flows to the desorption zone, that is, it can ensure that the air heated by the heater 500 can effectively remove the water vapor in the desorption zone corresponding to the hygroscopic wheel 400 without interfering with the absorption of water vapor in the air by the adsorption zone.

[0062] Furthermore, one end of the first partition 314 is connected to the base 312, and the other end of the first partition 314 is connected to the heater 500; one end of the second partition 315 is connected to the base 312, and the other end of the second partition 315 is connected to the heater 500; connecting the heater 500 between the first partition 314 and the second partition 315 can ensure that the air heated by the heater 500 can reliably flow to the desorption area of ​​the hygroscopic wheel 400, and then reliably utilize the heated air to make the moisture absorbed in the hygroscopic wheel 400 form water vapor and be taken out to achieve the humidification effect.

[0063] Furthermore, the first partition 314 is connected to the base 312 on the side facing the base 312, and the second partition 315 is connected to the base 312 on the side facing the base 312; in this way, the first area 316 and the second area 317 can be divided more reliably, and the adsorption area and the desorption area can be reliably divided on the moisture absorption wheel 400, thereby ensuring the reliability of water vapor absorption and desorption.

[0064] It should be noted that by arranging the heater 500 on the base 312 through the first partition 314 and the second partition 315, it can not only ensure that the heater 500 is reliably assembled on the base 312, but also improve the problem of direct contact between the heater 500 and the moisture absorption wheel 400, improve the problem of easy damage to the moisture absorption wheel 400, and improve the safety of use of the waterless humidification device 200.

[0065] The connection method between the heater 500 and the first partition plate 314, and the connection method between the heater 500 and the second partition plate 315 include but are not limited to snap connection, plug connection, and connection with fasteners such as bolts.

[0066] The connection method between the first partition 314 and the second partition 315 and the base 312 can be selected as needed. In a preferred embodiment, the first partition 314 and the second partition 315 are both integrally formed with the base 312. With this arrangement, there is no need to use fasteners to connect the first partition 314 and the second partition 315 to the base 312, which can reduce the number of through holes in the base 312 for setting fasteners, thereby improving the airtightness of the shell 310 and enhancing the user experience.

[0067] Of course, in other embodiments, the connection method between the first partition 314 and the second partition 315 and the base 312 includes but is not limited to snap connection or bonding.

[0068] It should be noted that by setting the heater 500 on the base 312 through the connection between the heater 500 and the first partition 314 and the second partition 315, the need to open through holes in the base 312 to set fasteners can be reduced, so that the heater 500 is connected to the base 312 through the fasteners, thereby improving the airtightness of the shell 310 and enhancing the user experience.

[0069] Please continue to refer to Figure 5 In this embodiment, the base 312 is provided with an outlet 318 that communicates with the interior of the volute 311 and is distributed within the second region 317. Positioning the outlet 318 of the base 312 within the second region 317 allows a portion of the air transported by the fan assembly 320 to reliably flow directly to the adsorption zone of the moisture absorbing wheel 400, thereby ensuring that the moisture absorbing wheel 400 can reliably absorb moisture from the air, thereby guaranteeing the humidification capacity of the waterless humidifier 200 and improving the user experience.

[0070] In order to make part of the air delivered by the fan assembly 320 in the volute 311 be blown directly to the adsorption area of ​​the moisture absorbing wheel 400, and the other part be blown to the heater 500 for heating and then flow to the desorption area of ​​the moisture absorbing wheel 400; please refer to Figure 4 and Figure 5The shell 310 also includes a guide plate 319, which is connected to the volute 311 and extends to the outlet 318, so that the wind transported by the fan blade assembly 320 is divided into two flows by the guide plate 319, one flow directly flows to the adsorption area of ​​the hygroscopic wheel 400, and the other flow flows to the heater 500 for heating and then flows to the desorption area of ​​the hygroscopic wheel 400.

[0071] Please refer to Figure 4 In this embodiment, the direction in which the air inlet 501 of the heater 500 points toward the air outlet 502 is a predetermined direction a, and the predetermined direction a is parallel to the end surface 401 of the moisture absorption wheel 400. By aligning the predetermined direction a, from which the air inlet 501 points toward the air outlet 502, with the end surface 401 of the moisture absorption wheel 400, the problem of hot air heated by the heater 500 and flowing toward the moisture absorption wheel 400 directly flowing toward and entering the moisture absorption wheel 400 is alleviated. The air heated by the heater 500 can be mixed with the unheated air within the housing 310 before flowing toward the moisture absorption wheel 400, thereby ensuring that the temperature of the air entering the moisture absorption wheel 400 is not too high. This can also alleviate the problem of the moisture absorption wheel 400 being easily damaged by high temperatures, thereby reducing maintenance costs and improving the user experience.

[0072] It should be understood that in other embodiments, please refer to Figure 6 The preset direction a is distributed at an angle to the end surface 401 of the moisture absorption wheel 400 and extends in a direction away from the end surface 401. By distributing the preset direction a at an angle to the end surface 401 of the moisture absorption wheel 400 and extending in a direction away from the end surface 401 of the moisture absorption wheel 400, the problem of hot air heated by the heater 500 and flowing toward the moisture absorption wheel 400 directly flowing toward and entering the moisture absorption wheel 400 can be improved. The air heated by the heater 500 can be mixed with the unheated air in the housing 310 before flowing toward the moisture absorption wheel 400, thereby ensuring that the temperature of the air entering the moisture absorption wheel 400 is not too high. This can also improve the problem of the moisture absorption wheel 400 being easily damaged due to high temperature, thereby reducing maintenance costs and improving user experience.

[0073] Please note that, please refer to Figure 5 In this embodiment, the air inlet 501 of the heater 500 is set toward the second area 317, and the air outlet 502 is set toward the first area 316; in this way, it can be ensured that one of the paths of the air output by the fan blade assembly 320 after being separated by the guide plate 319 can reliably flow to the heater 500 for heating, and the heated air can reliably flow to the desorption area of ​​the moisture absorption wheel 400, thereby ensuring the reliability of humidification.

[0074] To improve the safety of the waterless humidifier 200, please refer to Figure 4 and Figure 5The heater 500 includes a hood 510 and a heater body 520. The heater body 520 is disposed within the hood 510. The hood 510 has an air inlet 501 and an air outlet 502. The hood 510 is disposed on the air supply mechanism 300. Specifically, the hood 510 is connected to the first partition 314 and the second partition 315 so that the hood 510 is disposed on the base 312. Placing the heater body 520 within the hood 510 can alleviate safety issues caused by the high temperatures generated by the heater body 520 and help improve the problem of moisture absorption wheel 400 being easily damaged by high temperatures, thereby reducing maintenance costs and improving user experience.

[0075] Furthermore, the wind hood 510 of this embodiment is a sheet metal wind hood; the use of a sheet metal wind hood can improve the problem of the wind hood 510 being deformed or even burned at high temperatures due to the high temperature of the heater body 520, thereby improving safety; it can also effectively improve the problem that the hygroscopic wheel 400 is easily damaged by high temperatures.

[0076] It should be understood that in other embodiments, the wind shield 510 may also be a high-temperature resistant plastic wind shield, etc., which is not specifically limited here.

[0077] It should be noted that the heater body 520 includes but is not limited to a mica electric heater and a ceramic electric heater; the way in which the heater body 520 is arranged in the air hood 510 includes but is not limited to snap-fitting, bonding, etc.

[0078] Please refer to Figure 5 The wind shield 510 of this embodiment includes a first side wall 521, a second side wall 522, a third side wall 523 and a fourth side wall 524 that are angled and connected end to end in sequence. One end of the first side wall 521, one end of the second side wall 522, one end of the third side wall 523 and one end of the fourth side wall 524 together form an air inlet 501, and the other end of the first side wall 521, the other end of the second side wall 522, the other end of the third side wall 523 and the other end of the fourth side wall 524 together form an air outlet 502; wherein the second side wall 522 and the fourth side wall 524 are both distributed parallel to the end surface 401. By making the second side wall 522 and the fourth side wall 524 parallel to the end face 401 of the hygroscopic wheel 400, the airflow flowing from the air inlet 501 to the air outlet 502 can be roughly parallel to the end face 401 of the hygroscopic wheel 400, which can improve the problem of the gas heated by the heater 500 flowing directly to the hygroscopic wheel 400, and further improve the problem of the hygroscopic wheel 400 being easily damaged by high temperature, thereby reducing maintenance costs and improving user experience.

[0079] Furthermore, the first side wall 521 and the third side wall 523 are both perpendicular to the end face 401. When the second side wall 522 and the fourth side wall 524 are both parallel to the end face 401 of the moisture absorption wheel 400, the first side wall 521 and the third side wall 523 are both perpendicular to the end face 401 of the moisture absorption wheel 400, so that the air cover 510 can be roughly formed into a cubic frame structure. This not only improves the problem of the gas heated by the heater 500 directly flowing to the moisture absorption wheel 400, but also ensures a compact structural design of the heater 500, thereby reducing the assembly space required for the heater 500, ensuring a compact and miniaturized design of the waterless humidification device 200 and improving the user experience.

[0080] It should be understood that in other embodiments, the angles between the first side wall 521 and the third side wall 523 and the moisture absorption wheel 400 may be 120°, 135°, 75°, etc., and either the second side wall 522 or the fourth side wall 524 may be arranged at an angle to the end surface 401, without specific limitations herein. In other embodiments, the angles between the extended surfaces of the second side wall 522 and the fourth side wall 524 and the end surface 401 of the moisture absorption wheel 400 may be 1°, 2°, etc., without specific limitations herein.

[0081] The specific structure of the wind cover 510 can be selected as needed. For example, the wind cover 510 includes two frames that are interlocked and connected, or the wind cover 510 includes four sheet metal plates, which are welded or clamped in sequence, etc., which is not specifically limited here.

[0082] Please refer to Figure 5 In this embodiment, the first side wall 521 is connected to the first partition 314, and the third side wall 523 is connected to the second partition 315, so that the heater 500 can be reliably assembled on the base 312; and the heater 500 does not need to be directly connected to the base 312 through fasteners, which can reduce the through holes opened in the base 312, thereby ensuring the airtightness of the shell 310 and ensuring the user experience of the waterless humidification device 200.

[0083] The connection method between the first side wall 521 and the first partition 314, and the connection method between the third side wall 523 and the second partition 315 include but are not limited to snap connection, plug-in connection, connection with fasteners such as bolts, bonding, etc., and are not specifically limited here.

[0084] The air conditioner 010 of this embodiment can not only be used for cooling or heating, but can also use the waterless humidification device 200 to increase the air humidity; the working principle of the waterless humidification device 200 includes: the fan blade assembly 320 draws outdoor air into the shell 310, and then the air in the shell 310 can be divided into two paths, one path is directly blown to the moisture absorption wheel 400, so that the moisture absorption wheel 400 absorbs the water vapor therein and discharges the moisture absorbed air outdoors, and the other path is blown to the heater 500, and the gas heated by the heater 500 flows to the moisture absorption wheel 400, so that the water vapor absorbed by the moisture absorption wheel 400 is removed by high temperature and blown into the room, thereby achieving humidification.

[0085] In summary, the waterless humidifying device 200 of the present invention can be configured in the air conditioner 010. The waterless humidifying device 200 can improve the problem that the moisture absorption wheel 400 is easily damaged, which is beneficial to reduce maintenance costs and improve user experience.

[0086] 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.
