[0007] The heating device is arranged in the air inlet duct and is located between the humidifying belt and the fan;

[0008] The fan is used to guide the airflow into the air inlet duct, air outlet duct and cooling air duct. When the fan is running, the humidifying belt is used to absorb moisture in the airflow of the air outlet duct and then transfer it into the air inlet duct, and evaporate the moisture under the heating action of the heating device. The moisture is discharged from the air inlet along with the airflow for humidification.

[0009] The dry humidification device provided by the present invention has the following beneficial effects compared with the prior art:

[0010] In this dry humidifying device, the humidifying belt can rotate around the fan, and in the process of the humidifying belt rotating around the fan, it passes through the air inlet duct, the cooling duct and the air outlet duct in sequence; when the fan is running, the humidifying belt entering the air outlet duct can absorb moisture in the air flow; the humidifying belt entering the air inlet duct can evaporate moisture under the action of the air flow heated by the heating device, so that the evaporated moisture is discharged from the air inlet along with the air flow to humidify the designated area; the humidifying belt entering the cooling duct is cooled by the air flow to facilitate the absorption of moisture in the air outlet duct.

DETAILED DESCRIPTION

[0034] 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.

[0035] With the development of technology, air conditioners, which regulate air quality, have become a part of most people's lives. However, as quality of life continues to improve, the demands placed on air conditioners are also increasing. To further enhance their air conditioning capabilities, most air conditioners are equipped with a humidification function.

[0036] Some air conditioners require additional water to humidify a specific area, which can be inconvenient for the user. In response to this, a dry humidifier has been proposed that can humidify a specific area without the need for additional water.

[0037] However, the existing dry humidifying devices are usually large in size, thereby increasing the volume of the air conditioner, which not only increases the production cost of the air conditioner, but also affects the transportation and installation of the air conditioner, and also causes great inconvenience to users.

[0038] In order to improve the above technical problem, that is, to improve the technical problem of the large size of the dry humidifying device in the prior art, a dry humidifying device 10 of the present application and an air conditioner (not shown) using the dry humidifying device 10 are provided.

[0039] It should be noted that the air conditioner includes an indoor air conditioner unit and an outdoor air conditioner unit. The indoor air conditioner unit is installed in a designated area, and the indoor air conditioner unit can provide air conditioning to the designated area, thereby improving the air quality in the designated area and improving the comfort of users inside the designated area. The outdoor air conditioner unit is set in an area outside the designated area, and the indoor air conditioner unit and the outdoor air conditioner unit are connected to facilitate the circulation of the refrigerant between the indoor air conditioner unit and the outdoor air conditioner unit. Among them, the dry humidifying device 10 provided in the present application can be set on the indoor air conditioner unit or on the outdoor air conditioner unit. When the dry humidifying device 10 is set on the indoor air conditioner unit, the dry humidifying device 10 can directly introduce the airflow for humidification into the designated area, thereby humidifying the designated area; when the dry humidifying device 10 is set on the outdoor air conditioner unit, the dry humidifying device 10 can introduce the airflow to the designated area through a pipe, thereby providing humidification to the designated area.

[0040] In the examples of this application, please refer to Figure 1 The dry humidification device 10 includes a housing 100, a fan 200, a humidification belt 300, and a heating device 400. The fan 200 is disposed in the housing 100, and an air inlet duct 101, an air outlet duct 102, and a cooling duct 103 are formed in the housing 100 around the fan 200. When the fan 200 is in operation, the fan 200 can simultaneously introduce airflow into the air inlet duct 101, the air outlet duct 102, and the cooling duct 103. In addition, the housing 100 is also provided with an air inlet 150 connected to the air inlet duct 101 and an air outlet 160 connected to the air outlet duct 102; in other words, the airflow introduced into the air inlet duct 101 by the fan 200 is discharged from the air inlet 150, and the airflow introduced into the air outlet duct 102 by the fan 200 is discharged from the air outlet 160. It is worth noting that the air inlet 150 is connected to a designated area to introduce humidified airflow into the designated area; the air outlet 160 is connected to a space outside the designated area to direct the airflow passing through the outlet duct 102 to a space outside the designated area. The humidifying belt 300 is rotatably disposed within the housing 100 and is disposed around the fan 200 so that the humidifying belt 300 passes through the air inlet duct 101, the air outlet duct 102, and the cooling duct 103; that is, as the humidifying belt 300 rotates around the fan 200, the humidifying belt 300 shuttles between the air inlet duct 101, the air outlet duct 102, and the cooling duct 103. Furthermore, the humidifying belt 300 is configured to absorb moisture from the airflow as it passes through the outlet duct 102. The heating device 400 is disposed in the air inlet duct 101 and is located between the humidifying belt 300 and the fan 200.

[0041] Optionally, the air inlet 150 and the air outlet 160 are provided on two opposite side surfaces of the housing 100. Disposing the air inlet 150 and the air outlet 160 on two opposite side surfaces of the housing 100 can facilitate the airflow in the air inlet duct 101 to be directly discharged from the air inlet 150, and facilitate the airflow in the air outlet duct 102 to be discharged from the air outlet 160. Furthermore, when the dry humidifying device 10 is provided on an air conditioner outdoor unit, disposing the air inlet 150 and the air outlet 160 on opposite side surfaces of the housing 100 can also facilitate the installation of pipes, so as to facilitate the connection of the pipes to the air inlet 150 and the air outlet 160. It should be understood that the location of the air inlet 150 and the air outlet 160 can be designed according to the actual installation conditions of the dry humidifying device 10.

[0042] It should be noted that the humidifying belt 300 is arranged in a ring, and part of the humidifying belt 300 is located in the air inlet duct 101, part of the humidifying belt 300 is located in the air outlet duct 102, and part of the humidifying belt 300 is located in the cooling air duct 103. When the humidifying belt 300 rotates around the fan 200, the humidifying belt 300 cyclically shuttles through the air inlet duct 101, the air outlet duct 102, and the cooling air duct 103.

[0043] The fan 200 draws air from a space outside the designated area and then directs it into the inlet duct 101, outlet duct 102, and cooling duct 103. The airflow entering the outlet duct 102 passes through the humidifying belt 300, which absorbs moisture from the airflow and carries it back to the inlet duct 101. Once in the inlet duct 101, the airflow, heated by the heating device 400, passes through the humidifying belt 300. Simultaneously, the heated airflow evaporates the moisture on the heating belt, causing it to mix with the airflow. This moisture is then directed into the designated area through the air inlet 150, thereby providing humidification to the designated area. The heated airflow causes the humidifying belt 300 to reach a high temperature after passing through the air inlet duct 101. The hot humidifying belt 300 then enters the cooling channel, where the airflow passing through the cooling duct 103 cools the humidifying belt 300. This allows the humidifying belt 300 to absorb moisture after passing through the cooling duct 103 and entering the air outlet duct 102. This allows humidification to be applied to a designated area.

[0044] As described above, in the dry humidification device 10, the humidification belt 300 can rotate around the fan 200, and in the process of the humidification belt 300 rotating around the fan 200, it passes through the air inlet duct 101, the cooling air duct 103 and the air outlet duct 102 in sequence; when the fan 200 is running, the humidification belt 300 entering the air outlet duct 102 can absorb moisture in the air flow; the humidification belt 300 entering the air inlet duct 101 can evaporate moisture under the action of the air flow heated by the heating device 400, so that the evaporated moisture is discharged from the air inlet 150 along with the air flow to humidify the designated area; the humidification belt 300 entering the cooling air duct 103 is cooled by the air flow to facilitate the absorption of moisture in the air outlet duct 102. Since the humidifying belt 300 is arranged around the fan 200, and the air inlet duct 101, the air outlet duct 102 and the cooling duct 103 are all arranged around the fan 200, the humidification function can be completed by one fan 200, thereby reducing the parts of the dry humidifying device 10, thereby reducing the volume of the dry humidifying device 10, and improving the technical problem of the large volume of the dry humidifying device 10 in the prior art.

[0045] Optionally, in some embodiments of the present application, the housing 100 includes a main body 110, a first partition 120, a second partition 130, and a third partition 140. A housing space is provided within the main body 110 to accommodate the fan 200, the first partition 120, the second partition 130, the third partition 140, the humidification belt 300, and the heating device 400. The fan 200 is disposed within the main body 110. The first partition 120, the second partition 130, and the third partition 140 are spaced apart within the main body 110, and the first partition 120, the second partition 130, and the third partition 140 are disposed around the fan 200. Among them, an air inlet duct 101 is formed between the first partition 120 and the second partition 130; a cooling air duct 103 is formed between the second partition 130 and the third partition 140; and an air outlet duct 102 is formed together by the side of the first partition 120 away from the air inlet duct 101 and the side of the third partition 140 away from the cooling air duct 103.

[0046] By setting the first partition 120, the second partition 130, and the third partition 140, the airflow derived from the fan 200 can be divided into three parts by the first partition 120, the second partition 130, and the third partition 140. The airflows of the three parts enter the air inlet duct 101, the air outlet duct 102, and the cooling duct 103 respectively, so as to avoid the airflows between the three ducts from affecting each other. In addition, the first partition 120, the second partition 130, and the third partition 140 can also provide a guiding effect for the airflow to facilitate the flow of the airflow. Moreover, since the air ducts are divided by the first partition 120, the second partition 130, and the third partition 140, the space occupied by the first partition 120, the second partition 130, and the third partition 140 is small, the airflow formed by the fan 200 can be fully utilized to improve the humidification effect.

[0047] It should be understood that in other embodiments of the present application, other methods may be used to form the air inlet duct 101, the air outlet duct 102, and the cooling air duct 103. For example, three channel tubes may be provided inside the housing 100, and the internal channels of the three channel tubes may respectively form the air inlet duct 101, the air outlet duct 102, and the cooling air duct 103. For another example, three housings 100 may be provided, and the air inlet duct 101, the air outlet duct 102, and the cooling air duct 103 may be respectively formed inside the three housings 100.

[0048] In order to facilitate the arrangement of the humidifying belt 300, in some embodiments of the present application, a guide groove 121 is provided on the first partition 120, the second partition 130, and the third partition 140. The humidifying belt 300 can be movably arranged inside the guide groove 121 so that the humidifying belt 300 passes through the air inlet duct 101, the air outlet duct 102, and the cooling duct 103. In the process of the humidifying belt 300 rotating around the fan 200, the humidifying belt 300 shuttles through the guide groove 121. The guide groove 121 can provide a guiding function for the humidifying belt 300 to facilitate the rotation of the humidifying belt 300 around the fan 200. Of course, the guide groove 121 can also provide a limiting function for the humidifying belt 300 to prevent the position of the humidifying belt 300 from shifting, thereby improving the stability of the humidifying belt 300.

[0049] It should be understood that in other embodiments of the present application, the humidifying belt 300 may be arranged in other ways. For example, the first partition 120, the second partition 130, and the third partition 140 are each split into two plates, and the two plates are spaced apart so that the humidifying belt 300 can pass through the gap between the two plates, thereby providing a guiding and limiting effect on the humidifying belt 300. For another example, the humidifying belt 300 is arranged between the first partition 120, the second partition 130, and the third partition 140 and the fan 200. In other words, the humidifying belt 300 is arranged around the fan 200, and the first partition 120, the second partition 130, and the third partition 140 are arranged around the humidifying belt 300. For example, the humidifying belt 300 is set at one end of the first partition 120, the second partition 130 and the third partition 140 away from the fan 200, and the pressure is changed. The first partition 120, the second partition 130 and the third partition 140 are arranged around the fan 200, and the humidifying belt 300 is set around the first partition 120, the second partition 130 and the third partition 140, etc.

[0050] It should be noted that the setting of the guide groove 121 can also enable the first partition 120, the second partition 130 and the third partition 140 to provide support to the humidification belt 300, so that the humidification belt 300 can be formed into a ring to be arranged around the fan 200, thereby reducing the number of tensioning devices for tensioning the humidification belt 300, thereby reducing the production cost of the dry humidification device 10.

[0051] Optionally, in some embodiments of the present application, the end of the first baffle 120 away from the fan 200 is connected to the inner peripheral wall of the main body 110; the end of the second baffle 130 away from the fan 200 is connected to the peripheral wall of the main body 110; the end of the third baffle 140 away from the fan 200 forms a gap 141 with the peripheral wall of the main body 110; and the cooling duct 103 and the outlet duct 102 are connected through the gap 141. As a result, the inlet duct 101 and the outlet duct 102 are separated by the first baffle 120, preventing the airflows between the inlet duct 101 and the outlet duct 102 from interfering with each other, thereby ensuring effective humidification. Furthermore, by connecting the cooling channel and the outlet duct 102 through the gap 141, the airflow from the cooling duct 103 can be directed into the outlet duct 102, thereby being discharged to a space outside the designated area. This saves the cost of providing a separate duct to guide the airflow from the cooling duct 103, thereby achieving the goal of reducing costs.

[0052] Of course, the air outlet duct 102 and the cooling air duct 103 may also be connected in other ways, for example, a through hole connecting the air outlet duct 102 and the cooling air duct 103 is opened on the third partition plate 140 .

[0053] In addition, in some embodiments of the present application, a first angle is formed between the first partition 120 and the second partition 130, and a second angle is formed between the second partition 130 and the third partition 140; the first angle is greater than the second angle. To ensure that the moisture in the humidification belt 300 can be effectively evaporated, thereby improving the humidification effect, the spatial volume of the air inlet duct 101 needs to be designed to be sufficiently large. However, since the humidification belt 300 cools quickly, the space requirement for the cooling duct 103 is not high. Based on this, the angle of the first angle is designed to be greater than the second angle, so that the spatial volume of the air inlet duct 101 is greater than the spatial volume of the cooling duct 103.

[0054] Optionally, the first angle is less than or equal to 90°, and the second angle is an acute angle. Optionally, the angle of the first angle can be 45°, 50°, 55°, 60°, 65°, 70°, 75°, 80°, 85° or 90°, etc. In addition, the angle of the second angle can be 30°, 35°, 40°, 45°, 50°, 55° or 60°, etc. Through the above-mentioned setting method, the spatial volume of the air outlet duct 102 can be made larger, so that the humidification belt 300 can fully absorb moisture in the air outlet duct 102, and the humidification capacity of the dry humidification device 10 can be improved. It should be understood that in other embodiments of the present application, the setting of the first angle and the setting of the second angle can be adjusted according to actual conditions.

[0055] The humidification belt 300 includes multiple humidification blocks 310 and multiple flexible connectors 320. The flexible connectors 320 are made of a soft material that can be easily bent, giving the humidification belt 300 an overall belt-like shape. The humidification blocks 310 are used to absorb moisture from the airflow as it passes through the outlet duct 102. Any two adjacent humidification blocks 310 are connected by the flexible connectors 320, forming a ring around the blower 200.

[0056] To facilitate the driving of the humidifying belt 300, in some embodiments of the present application, the humidifying belt 300 may be driven by a belt drive. In other words, a plurality of pulleys are provided inside the housing 100, and the humidifying belt 300 is wound around the plurality of pulleys, so that the humidifying belt 300 is arranged around the fan 200 through the driving action of the pulleys. Alternatively, a chain drive may be adopted. In other words, a plurality of sprockets are provided inside the housing 100, and a toothed structure adapted to the sprockets is provided on the inner side of the humidifying belt 300, so that the sprockets can drive the humidifying belt 300 to be arranged around the fan 200.

[0057] Of course, in order to enable the humidification belt 300 to be arranged around the fan 200, multiple pulleys or multiple sprockets need to be arranged on the outer edge of the internal space of the shell 100, thereby providing support to the humidification belt 300, so that the humidification belt 300 can be arranged around the fan 200.

[0058] Optionally, in an embodiment of the present application, the humidifying block 310 is made of zeolite, silica gel or a polymer adsorbent.

[0059] To sum up, in the dry humidification device 10 and the air conditioner provided in the embodiment of the present application, the humidification belt 300 can rotate around the fan 200, and in the process of the humidification belt 300 rotating around the fan 200, it passes through the air inlet duct 101, the cooling air duct 103 and the air outlet duct 102 in sequence; when the fan 200 is running, the humidification belt 300 entering the air outlet duct 102 can absorb moisture in the air flow; the humidification belt 300 entering the air inlet duct 101 can evaporate moisture under the action of the air flow heated by the heating device 400, so that the evaporated moisture is discharged from the air inlet 150 along with the air flow to humidify the designated area; the humidification belt 300 entering the cooling air duct 103 is cooled by the air flow to facilitate the absorption of moisture in the air outlet duct 102. Since the humidifying belt 300 is arranged around the fan 200, and the air inlet duct 101, the air outlet duct 102 and the cooling duct 103 are all arranged around the fan 200, the humidification function can be completed by one fan 200, thereby reducing the parts of the dry humidifying device 10, thereby reducing the volume of the dry humidifying device 10, and improving the technical problem of the large volume of the dry humidifying device 10 in the prior art.

[0060] 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.
