Description

Technical Field

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

[0002] Currently, air conditioners are available on the market that use waterless humidification devices to achieve waterless humidification. The waterless humidification module can humidify the air entering the room without adding additional water, thereby ensuring the humidity of the indoor air. It does not require the user to manually add water, making it more convenient to use. Existing waterless humidification devices include two fans, a humidification wheel, a heating component, etc. The principle is that the first fan forms a first air path. The first air path is "outdoor-outdoor". A section of the humidification wheel is set in the first air path, so it can absorb moisture from the outdoor air. The second fan forms a second air path. The second air path is "outdoor-indoor". The other part of the humidification wheel and the heating component are set in the second air path. When the hot air passes through the humidification wheel, it removes the moisture adsorbed on the humidification wheel and pours it into the room, thereby humidifying the indoor environment.

[0003] However, most of the waterless humidification modules in the prior art have relatively complex structures, resulting in a large volume of the waterless humidification structure. Summary of the Invention

[0007] Part of the outdoor air introduced by the fan is adsorbed and then discharged to the outside through the outdoor air outlet. Part of the outdoor air is humidified by desorbing moisture from the hygroscopic material. The partition separates the lower cover of the rotor into a desorption zone and an adsorption zone. The rotor can simultaneously realize the functions of desorption and adsorption, reducing the parts of the waterless humidification structure, simplifying the structure, reducing the volume of the waterless humidification structure, and integrating more functions into the waterless humidification structure, making the entire waterless humidification structure more miniaturized and increasing the scenarios where it can be installed and used.

DETAILED DESCRIPTION

[0025] 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.

[0026] First embodiment

[0027] See also Figure 1 and Figure 2 This embodiment provides a waterless humidification structure 100. In the waterless humidification structure 100 provided in this embodiment, the rotor 120 can simultaneously realize the functions of desorption and adsorption, which can reduce the components of the entire waterless humidification structure 100, thereby reducing the volume of the waterless humidification structure 100.

[0028] The waterless humidification structure 100 provided in this embodiment is applied to the indoor unit of an air conditioner 10. It humidifies incoming indoor air without the need for additional water, thereby ensuring a constant humidity level. However, most existing waterless humidification modules have complex structures, resulting in a large volume for the waterless humidification structure 100. The waterless humidification structure 100 provided in this embodiment can alleviate this problem. The rotor 120 can simultaneously perform desorption and adsorption functions, reducing the number of components in the entire waterless humidification structure 100 and thus reducing its volume.

[0029] See also Figure 1-Figure 3 In this embodiment, the waterless humidification structure 100 includes a rotor lower cover 110, a rotor 120 having a hygroscopic material, a fan 160, a driving member and a separator 130. The rotor 120 is installed on the rotor lower cover 110. The driving member is in transmission connection with the rotor 120 to drive the rotor 120 to rotate relative to the rotor lower cover 110. The fan 160 is arranged on the side of the rotor 120 away from the rotor lower cover 110. The separator 130 is arranged on the rotor lower cover 110. The separator 130 The lower cover 110 of the rotor is divided into a desorption zone 111 and an adsorption zone 112. The desorption zone 111 is provided with an indoor air outlet 115, and the adsorption zone 112 is provided with an outdoor air outlet 116. Part of the outdoor air sent out by the fan 160 passes through the rotor 120 to absorb moisture and is discharged from the outdoor air outlet 116 of the adsorption zone 112. Part of the outdoor air sent out by the fan 160 passes through the rotor 120, absorbs moisture on the rotor 120, and is discharged from the indoor air outlet 115 of the desorption zone 111.

[0030] In this embodiment, the partition 130 divides the rotor lower cover 110 into a desorption zone 111 and an adsorption zone 112. When the driving member drives the rotor 120 to rotate relative to the rotor lower cover 110, the hygroscopic material on the rotor 120 rotates with the rotor 120 from the desorption zone 111 to the adsorption zone 112, and then from the adsorption zone 112 to the desorption zone 111. The rotor 120 corresponding to the adsorption zone 112 performs adsorption processing on the outdoor air, absorbs moisture in the air, and discharges this portion of outdoor air to the outside through the outdoor air outlet 116. The hygroscopic material on the rotor 120 rotates with the rotor 120 again to the desorption zone 111. This portion of the hygroscopic material contains a large amount of moisture, and desorbs the air passing through this portion, allowing the air to absorb the moisture attached to this portion of the hygroscopic material, thereby humidifying the air, and then discharges it to the indoor air outlet 115. In this embodiment, the separator 130 separates the rotor lower cover 110 into a desorption area 111 and an adsorption area 112 , and the rotor 120 can simultaneously achieve the functions of desorption and adsorption.

[0031] In this embodiment, part of the outdoor air introduced by the fan 160 is adsorbed and then discharged to the outside through the outdoor air outlet 116, and part of the outdoor air is humidified by desorbing moisture from the hygroscopic material. The partition 130 separates the lower cover 110 of the rotor into a desorption area 111 and an adsorption area 112. The rotor 120 can simultaneously realize the functions of desorption and adsorption, reducing the parts of the waterless humidification structure 100 and simplifying the structure.

[0032] In this embodiment, the waterless humidification structure 100 also includes a heating element 170, which is arranged on the side of the wheel 120 away from the lower plate of the wheel 120 and is arranged corresponding to the desorption zone 111. Part of the outdoor air sent out by the fan 160 is heated by the heating element 170 in turn, absorbs moisture on the wheel 120, and is discharged from the indoor air outlet 115.

[0033] The heating element 170 is arranged in correspondence with the desorption zone 111 and is mainly used to heat the outdoor air entering the desorption zone 111. The hygroscopic material of the rotor 120 can absorb moisture in a low-temperature, high-humidity environment, release moisture after being heated, and continue to absorb moisture after cooling, repeating the cycle. The waterless humidification structure 100 is mainly used to humidify the indoor environment. In winter, if the indoor environment becomes dry after the heating mode is turned on for a long time, the waterless humidification structure 100 is needed to humidify the air entering the room. In winter, the temperature of the outdoor air is generally low, and the outdoor air itself is low. After part of the outdoor air sent by the fan 160 passes through the hygroscopic material, the hygroscopic material can absorb moisture in the air. The other part of the outdoor air, after being heated by the heating element 170 and reaching a certain temperature, can desorb moisture from the hygroscopic material after passing through the hygroscopic material, achieving the purpose of humidification. This part of the outdoor air can be directly sent into the room through the indoor air outlet 115.

[0034] Figure 1 The direction of the hollow arrow indicates the flow of outdoor air. The waterless humidification structure 100 also includes an integrated cover 180. The fan 160 and the heater 170 are both disposed within the integrated cover 180. The integrated cover 180 is disposed on one side of the rotor 120 and connected to the rotor lower cover 110. The integrated cover 180 is provided with an air inlet 182. After the fan 160 is started, the outdoor air inlet 182 enters the integrated cover 180, forming two air paths within the integrated cover 180. The outdoor air in one of the air paths passes through the hygroscopic material corresponding to the adsorption zone 112. The hygroscopic material absorbs moisture from the air, and the adsorbed outdoor air is discharged from the outdoor air outlet 116. The outdoor air in the other air path is directly heated by the heater 170, reaches a certain temperature, and then passes through the hygroscopic material, which desorbs moisture from the hygroscopic material, achieving the purpose of humidification. This portion of outdoor air can be directly delivered into the room through the indoor air outlet 115.

[0035] In this embodiment, the rotor lower cover 110 is disposed below the integrated cover 180, so that the humidified outdoor air can be discharged into the room through the indoor air outlet 115, thereby achieving the purpose of indoor humidification.

[0036] In this embodiment, the rotor lower cover 110 includes a bottom plate 113 and side plates 114 . The side plates 114 are connected end to end and are arranged around the bottom plate 113 . The rotor 120 cooperates with the side plates 114 and is spaced apart from the bottom plate 113 .

[0037] In this embodiment, the wheel 120 and the bottom plate 113 are spaced apart so that the desorption area 111 and the adsorption area 112 form cavities respectively. The partition 130 separates the bottom plate 113 to reduce the risk of mixing of the desorbed air and the adsorbed air, thereby ensuring the humidity of the air entering the indoor environment.

[0038] In this embodiment, the indoor air outlet 115 is disposed on the bottom plate 113 .

[0039] The indoor air outlet 115 is set on the bottom plate 113. The indoor air outlet 115 is connected to the indoor environment. After the outdoor air passes through the rotor 120, it absorbs the moisture on the rotor 120 and enters the indoor environment from the indoor air outlet 115 at the bottom. It can reduce the path of the air in the desorption area 111 and allow the humidified air to directly enter the indoor environment.

[0040] In this embodiment, the outdoor air outlet 116 is provided on the side panel 114 .

[0041] Among them, the outdoor air passes through the rotor 120 to absorb moisture in the air and is discharged to the outside through the outdoor air outlet 116. The air with adsorbed moisture is discharged to the outside in time, reducing the risk of mixing of desorbed air and adsorbed air, thereby ensuring the humidity of the air entering the indoor environment.

[0042] In this embodiment, the waterless humidification structure 100 further includes a connecting shaft 140, which is mounted on the bottom plate 113 and has a rotating shaft connected to the impeller 120. The partition 130 includes a first partition plate 132 and a second partition plate 134, which are mounted on the bottom plate 113. One end of the first partition plate 132 is connected to the connecting shaft 140, and the other end of the first partition plate 132 is connected to the side plate 114. One end of the second partition plate 134 is connected to the connecting shaft 140, and the other end of the second partition plate 134 is connected to the side plate 114.

[0043] The side plate 114 is arranged on the bottom plate 113 in a ring, so that the entire rotor lower cover 110 is hollow and cylindrical. The first partition plate 132 is in the shape of an elongated strip, and the second partition plate 134 is also in the shape of an elongated strip. For the convenience of description, the long sides of the first partition plate 132 and the second partition plate 134 are referred to as the side parts, and the wide sides of the first partition plate 132 and the second partition plate 134 are referred to as the end parts. One end of the first partition plate 132 is connected to the connecting shaft 140, and the other end is connected to the side plate 114. One side of the first partition plate 132 is connected to the bottom plate 113, and the other side is in contact with the rotor 120. Similarly, one end of the second partition plate 134 is connected to the connecting shaft 140, and the other end is connected to the side plate 114. One side of the first partition plate 132 is connected to the bottom plate 113, and the other side is in contact with the rotor 120.

[0044] It is easy to understand that the side plate 114 is cylindrical and the bottom plate 113 is circular. Part of the side plate 114, part of the bottom plate 113, one side of the first partition plate 132, and one side of the second partition plate 134 form the desorption zone 111. Another part of the side plate 114, another part of the bottom plate 113, the other side of the first partition plate 132, and the other side of the second partition plate 134 form the desorption zone 111.

[0045] Similarly, in order to ensure the stability of the rotating wheel 120 during rotation, the connecting shaft 140 is usually set at the circular part of the bottom plate 113 so that the rotating wheel 120 can always cover the adsorption area 112 and the desorption area 111 during rotation.

[0046] In this embodiment, in order to increase the humidity of the indoor air while introducing outdoor air, the desorbed air is outdoor air and the adsorbed air is also outdoor air.

[0047] At the same time, in order to increase the humidity entering the room, the adsorption zone 112 is generally set to be relatively large, and the desorption zone 111 is generally set to be relatively small. The larger area of ​​the adsorption zone 112 can absorb as much moisture as possible from the outdoor air, allowing more moisture to adhere to the hygroscopic material. After the rotor 120 in this part rotates to the desorption zone 111, it can accelerate the humidification of the outdoor air, so that the air entering the room can have a higher humidity.

[0048] In this embodiment, the rotor lower cover 110 is circular, the connecting shaft 140 is disposed at the circular portion of the rotor lower cover 110 , and the center angle corresponding to the adsorption area 112 is 180 degrees to 270 degrees.

[0049] Since the adsorption area 112 is mainly used to adsorb moisture in the outdoor air, in order to ensure the humidity of the air entering the room, it is necessary to make the hygroscopic material have more moisture. Therefore, the adsorption area 112 is set to be relatively large, at least more than half of the entire rotor 120, that is, at least greater than 180.

[0050] However, if the adsorption area 112 is too large, the area of ​​the desorption area 111 will be smaller, which will affect the adsorption effect in the desorption area 111 and the air intake and humidity of the air entering the room. Therefore, the maximum angle of the adsorption area 112 is preferably not more than 270 degrees.

[0051] In this embodiment, the connecting shaft 140 is disposed at a circular portion of the rotor lower cover 110 , and the central angle of the desorption zone 111 is 90 degrees to 180 degrees.

[0052] In this embodiment, since the desorption zone 111 is mainly used to humidify the air, sufficient moisture must be ensured in the hygroscopic material to ensure the humidity of the air entering the room. Therefore, the area of ​​the desorption zone 111 should not exceed half of the entire rotor 120, that is, the maximum angle of the desorption zone 111 is 180 degrees.

[0053] However, if the area of ​​the desorption zone 111 is small, the adsorption effect in the desorption zone 111 will be affected, and the air volume and humidity of the air entering the room will be affected. Therefore, the minimum angle of the desorption zone 111 is preferably not less than 90 degrees.

[0054] It is easy to understand that the entire rotor lower cover 110 consists of two parts, the adsorption area 112 and the desorption area 111, and the sum of the angles between the two parts should be 360 ​​degrees. If the angle of the desorption area 111 is 90 degrees, the angle of the adsorption area 112 is 270 degrees.

[0055] In this embodiment, the rotating wheel 120 abuts against the first partition plate 132 and the second partition plate 134 at a side away from the bottom plate 113 .

[0056] In this embodiment, the rotor 120 drives the hygroscopic material to rotate relative to the rotor lower cover 110, causing the hygroscopic material to repeatedly undergo the desorption and adsorption processes. To prevent air from flowing out of the adsorption zone 112 and the desorption zone 111, the adsorption zone 112 and the desorption zone 111 are formed into two enclosed areas. The rotor 120 abuts against the first and second partition plates 132, 134, respectively, on the side away from the bottom plate 113. This minimizes the gap between the first and second partition plates 132, 134, and the rotor 120, allowing the first and second partition plates 132, 134 to completely separate the adsorption zone 112 and the desorption zone 111, reducing air flow between the adsorption zone 112 and the desorption zone 111 and preventing dry air in the adsorption zone 112 from entering the desorption zone 111, causing mixed air and affecting the humidity of the air entering the room.

[0057] See also Figure 4In this embodiment, the waterless humidification structure 100 also includes an air outlet channel 150, one end of the air outlet channel 150 is connected to the outdoor air outlet 116, and the other end is set outdoors. The desorbed air enters the air outlet channel 150 from the outdoor air outlet 116 and is then discharged to the outdoors.

[0058] The working principle of the waterless humidification structure 100 provided in this embodiment is as follows: the fan 160 sends outdoor air into the rotor 120 with adsorption material, part of the outdoor air passes through the rotor 120 corresponding to the adsorption area 112, so that the rotor 120 of this part adsorbs moisture in the air, and the air after adsorption treatment is discharged from the outdoor air outlet 116, and another part of the outdoor air is heated by the heating element 170 and passes through the rotor 120, desorbing the moisture in the hygroscopic material corresponding to the desorption area 111, absorbing the moisture in this part of the hygroscopic material, and the humidified outdoor air is discharged into the room through the indoor air outlet 115.

[0059] Second embodiment

[0060] See also Figure 5 This embodiment provides an air conditioner 10. The air conditioner 10 provided in this embodiment can reduce the number of components of the entire waterless humidification structure 100, thereby reducing the volume of the waterless humidification structure 100.

[0061] For the sake of brief description, reference may be made to the first embodiment for matters not mentioned in this embodiment.

[0062] In this embodiment, the air conditioner 10 includes a main body 11 and the waterless humidification structure 100 provided in the first embodiment. The waterless humidification structure 100 is mounted on the main body 11. The main body 11 includes components such as a heat exchanger and an air outlet structure to achieve basic temperature control. The waterless humidification device is primarily used to humidify the indoor environment. The waterless humidification structure 100 absorbs moisture from the outdoor air and uses this moisture to humidify the outdoor air entering the room, eliminating the need for manual water addition and achieving waterless humidification.

[0063] The air conditioner 10 may be a wall-mounted indoor air conditioner, a cabinet air conditioner, or other types of air conditioning systems.

[0064] 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.
