Description

Technical Field

[0001] The present application relates to the technical field of air filtration, and particularly to an air conditioner. Background Art

[0002] At present, an air conditioner with a humidification function and a fresh air function can bring fresh and healthy air of nature into the room and improve the humidity of the indoor air. An air conditioner with a humidification function and a fresh air function usually sets a humidifying device and a filter screen in the air circulation channel. The air enters the room after being filtered by the filter screen and humidified by the humidifying device, so as to realize the functions of air humidification and fresh air.

[0003] For example, Chinese Patent (Publication No.: CN110701717A) discloses a fresh air device and an indoor unit of a fresh air-changing air conditioner. The fresh air device includes an air inlet module and a fan module communicated with the air inlet module, and the air inlet module is located below the fan module. In the air inlet module, an air inlet cavity is defined, and the air inlet cavity is communicated with a fresh air inlet pipe connecting to the outside. The outdoor fresh air enters the air inlet cavity through the fresh air inlet pipe. A humidifying component is arranged in the air inlet cavity for humidifying the outdoor fresh air. The humidifying component includes a U-shaped water tank horizontally arranged in the air inlet cavity, and water is injected into the U-shaped water tank for humidifying the outdoor fresh air. The outer edge of the U-shaped water tank is fixedly connected with the air inlet cavity, that is, this patent discloses a solution for realizing the functions of fresh air filtration and humidification by arranging a humidifying device and a filtering device in the air inlet cavity.

[0004] However, an air conditioner that sets a humidifying device and a filter screen in the air circulation channel cannot separately realize the functions of fresh air and air humidification. Therefore, exploring an air conditioner and a filter screen solution that can separately realize the functions of fresh air and air humidification has become the direction of efforts of those skilled in the art. Summary of the Invention

[0005] It should be noted that the following content is discovered by the inventor after in-depth research and should not be regarded as well-known to those skilled in the art.

[0006] During the research on an air conditioner that can separately realize the functions of fresh air and air humidification, the inventor found that by setting adjacent fresh air inlets and humidifying inlets, the functions of fresh air and air humidification can be separately realized by closing and opening the fresh air inlets and humidifying inlets, and the volume of the air conditioner can be reduced.

[0007] However, when setting the filter screen, since the fresh air inlets and the humidifying inlets are adjacent, the moist air at the humidifying inlets often enters the filter screen at the fresh air inlets, causing the filter screen for filtering fresh air to be moist and breeding a large number of bacteria. Furthermore, when separately realizing the fresh air function, fresh air containing a large number of bacteria will be introduced into the room.

The following description is provided to enable any person skilled in the art to make and use the present invention. In the following description, details are set forth for purposes of explanation. It should be understood that the present invention can be practiced without these specific details. In other instances, well-known structures and processes are not described in detail so as not to obscure the description of the present invention with unnecessary details. Therefore, the present invention is not intended to be limited to the embodiments shown, but is to be accorded the widest scope consistent with the principles and features disclosed in this application.

[0079] An embodiment of this application provides a filter net 40 and an air conditioner, which will be described in detail below respectively.

[0080] First, refer to Figure 1 and Figure 2 , Figure 1 which shows a schematic structural view of the first side 410 of the filter net 40 in an embodiment of this application, Figure 2 which shows a schematic structural view of the second side 420 of the filter net 40 in an embodiment of this application. The filter net 40 includes:

[0081] A filter net body 400, the filter net body 400 having opposite first side 410 and second side 420;

[0082] The first side 410 has a first filtering structure 411, and the second side 420 has a second filtering structure 421. Among them, the filtering resistance of the first filtering structure 411 during operation is less than the filtering resistance of the second filtering structure 421 during operation.

[0083] Specifically, the filter net body 400 forms a filtering structure to achieve the fresh air filtering function. Exemplarily, the filter net body 400 can be a HEAP filter net, a metal rubber filter net, a nylon filter net, a metal filter net, etc. It should be noted that this application does not specifically limit the shape of the filter net body 400. For the convenience of understanding, the shape of the filter net body 400 in this application is a cuboid shape. Those skilled in the art can understand that the shape of the filter net body 400 can also be other shapes, such as a regular hexagonal prism.

[0084] Among them, the filter net body 400 has opposite first side 410 and second side 420. Generally, in order to ensure that the filter net body 400 has a large filtering area, the first side 410 and the second side 420 are the sides with larger areas of the filter net body 400. For example, as Figure 1As shown, the first side 410 and the second side 420 are the left side and the right side of the filter net body 400 respectively. It can be understood that the first side 410 and the second side 420 can also be other sides of the filter net body 400, for example, as Figure 1 shown, the first side 410 and the second side 420 are the top surface and the bottom surface of the filter net body 400 respectively.

[0085] In order to prevent the moist air at the humidification air inlet 14 from entering the filter net 40 at the fresh air inlet 13 when the fresh air inlet 13 and the humidification air inlet 14 are adjacent, the first side 410 has a first filtering structure 411, and the second side 420 has a second filtering structure 421. Since the filtering resistance of the first filtering structure 411 during operation is less than that of the second filtering structure 421 during operation, the filtering resistance of the fresh air on the fresh air side can be reduced, and at the same time, the moist air on the humidification side can be prevented from entering the filter net 40, so as to avoid the phenomenon of a large number of bacteria breeding due to moisture in the filter net 40.

[0086] In some embodiments of the present application, the filtering resistance of the first filtering structure 411 being less than that of the second filtering structure 421 can be achieved by setting the extending direction of the flow channel. For example, refer to Figure 1 、 Figure 2 and Figure 3 , Figure 3 shows Figure 2 a partial enlarged schematic view of A in

[0087] In the above embodiment, since the first direction has a direction component perpendicular to the second direction, the first filtering channel 4111 and the second filtering channel 4211 are channels that are staggered with each other on both sides of the filter net body 400. When air flows into the filter net body 400 along the first direction, for example, as Figure 1The first direction shown is the direction perpendicular to the horizontal plane, and the second direction is the direction parallel to the horizontal plane. When air flows vertically upward from below the filter net body 400, fresh air enters through the first side 410. Since the inflow direction of the fresh air is the same as the first direction in which the first filter channel 4111 extends, the filtration resistance on the fresh air side can be reduced. When humidified air enters through the second side 420, since the flow direction of the humidified air and the fresh air are both along the first direction, that is, the flow direction of the humidified air has at least a component in the direction perpendicular to the second direction, the resistance for the humidified air to enter the filter net body 400 increases. Eventually, the filtration resistance of the fresh air is reduced and the filtration resistance of the humid air is increased to achieve the purpose of reducing the entry of the humid air on the humidification side into the filter net 40.

[0088] It should be noted that in some embodiments of the present application, for example, when the shape of the filter net body 400 is a cuboid shape, the preferred implementation mode of the present application is that the first side 410 is parallel to the second side 420, and the first direction is perpendicular to the second direction, so that the first direction and the second direction are completely perpendicular. Furthermore, when the humidified air and the fresh air flow in along the first direction, the humidified air is completely perpendicular to the second filter channel 4211, achieving the maximization of the filtration resistance of the humidified air. However, those skilled in the art can understand that the above first direction and second direction can have many other arrangement modes. For example, when the first side 410 is parallel to the second side 420, the included angle between the first direction and the second direction is 60°.

[0089] In addition, the different resistance magnitudes of the first filter structure 411 and the second filter structure 421 can also be achieved through other structures. For example, by setting filter holes with different densities and / or sizes on the first side 410 and the second side 420, the air filter holes formed on the first side 410 are larger in size and / or smaller in density, and the air filter holes formed on the second side 420 are smaller in size and / or larger in density, achieving the purpose that the filtration resistance of the first filter structure 411 on the first side 410 is less than the filtration resistance of the second filter structure 421 on the second side 420.

[0090] Furthermore, in order to further amplify the filtration resistance of the second filter structure 421 and reduce the filtration resistance of the first filter structure 411, the width of the first filter channel 4111 is greater than the width of the second filter channel 4211. Since the width of the first filter channel 4111 is greater than the width of the second filter channel 4211, the resistance for the air on the fresh air side to enter the first filter channel 4111 with a larger width is smaller, while the resistance for the humidified air on the humidification side to enter the first filter channel 4111 with a smaller width is greater. Exemplarily, the ratio of the width of the first filter channel 4111 to the width of the second filter channel 4211 can be 2:1 to 6:1.

[0091] While setting the widths of the first filtering channel 4111 and the second filtering channel 4211, the densities of the first filtering channel 4111 and the second filtering channel 4211 can also be changed to further increase the filtering resistance of the second filtering structure 421 and reduce the filtering resistance of the first filtering structure 411. Specifically, the density of the first filtering channel 4111 is greater than that of the second filtering channel 4211.

[0092] In the above embodiment, since the density of the first filtering channel 4111 is greater than that of the second filtering channel 4211, when the widths of the first filtering channel 4111 and the second filtering channel 4211 are equivalent or the width of the first filtering channel 4111 is greater than that of the second channel, the flow-through area of multiple first filtering channels 4111 is greater than that of the second filtering channel 4211. Therefore, the densities of the first filtering channel 4111 and the second filtering channel 4211 can be further changed to further increase the filtering resistance of the second filtering structure 421 and reduce the filtering resistance of the first filtering structure 411.

[0093] In some embodiments of the present application, the filtering resistance of the first filtering channel 4111 and the second filtering channel 4211 can also be changed by setting the depths of the first filtering channel 4111 and the second filtering channel 4211. For example, refer to Figure 3 , where the depth of the first filtering channel 4111 is greater than that of the second filtering channel 4211. Since the depth of the first filtering channel 4111 is greater than that of the second filtering channel 4211, more air can enter the first filtering channel 4111, and the gas volume accommodated by the second filtering channel 4211 decreases. As a result, the filtering resistance of the first filtering channel 4111 is reduced, and the filtering resistance of the second filtering channel 4211 is increased. Specifically, the ratio of the depth of the first filtering channel 4111 to the depth of the second filtering channel 4211 can be 2:1 to 8:1.

[0094] In some embodiments of the present application, for example, in the embodiment where the depth of the first filtering channel 4111 is greater than that of the second filtering channel 4211, to ensure the filtering effects of the first filtering channel 4111 and the second filtering channel 4211, continue to refer to Figure 3 , the width of the first filtering channel 4111 gradually decreases along the depth direction, and the width of the second filtering channel 4211 gradually decreases along the depth direction. That is, after fresh air or humidified air enters the interiors of the first filtering channel 4111 and the second filtering channel 4211, the air collides with the inner side surface of the first filtering channel 4111, causing the gas to generate turbulence and strengthening the collision with the filter mesh body 400, thereby ensuring the filtering effects of the first filtering channel 4111 and the second filtering channel 4211.

[0095] It can be understood that the cross-sections of the first filtering channel 4111 and the second filtering channel 4211 can be in the shapes of an inverted triangle, a trapezoid, etc., so as to make the width of the first filtering channel 4111 gradually decrease along the depth direction, and the width of the second filtering channel 4211 gradually decrease along the depth direction.

[0096] Furthermore, in order to facilitate the fresh air to pass through the filter net body 400 and avoid the phenomenon of excessive resistance of the filter net body 400, refer to Figure 3 , wherein, the sum of the depth h1 of the first filtering channel 4111 and the depth h2 of the second filtering channel 4211 is greater than the thickness H of the filter net body 400. Since the sum of the depth h1 of the first filtering channel 4111 and the depth h2 of the second filtering channel 4211 is greater than the thickness H of the filter net body 400, and since the first filtering channel 4111 and the second filtering channel 4211 are arranged in an interleaved manner, the first filtering channel 4111 and the second filtering channel 4211 are communicated to form a rectangular array of filtering holes, and the fresh air can pass through the filter net body through the rectangular array of filtering holes, avoiding the phenomenon that the filter net body 400 cannot pass air due to excessive filtering resistance.

[0097] It should be noted that the above-mentioned partial embodiments mainly provide an exemplary structure of the filter net 40 for how to achieve different filtering resistances on both sides. Those skilled in the art can make equivalent design changes in the specific implementation manners under the guidance of this application. For example, the filter net 40 is set as a three-layer structure, where the two outer layers respectively correspond to the first filtering structure 411 and the second filtering structure 421, and the middle layer is used as a filtering functional layer. By setting the two outer filtering layers to have different filtering resistances, the filtering resistance of the fresh air is reduced and the filtering resistance of the humid air is increased to achieve the purpose of reducing the entry of the humid air on the humidifying side into the filter net 40.

[0098] Furthermore, in order to better implement the filter net 40 in the embodiments of the present application, on the basis of the filter net 40, an air conditioner is further provided in the embodiments of the present application. Refer to Figure 4 and Figure 5 , Figure 4 shows an assembly schematic diagram of the air conditioner in the embodiments of the present application, Figure 5 shows an exploded schematic diagram of the air conditioner in the embodiments of the present application. The air conditioner includes the filter net 40 in any of the above embodiments. The air conditioner in the embodiments of the present application has all the beneficial effects of the above-mentioned filter net 40 due to the setting of the filter net 40 in the above embodiments, and will not be elaborated here.

[0099] Specifically, in order to facilitate the first side 410 and the second side 420 of the filter net 40 to respectively correspond to the fresh air inlet 13 and the humidifying air inlet 14, refer to Figure 4 andFigure 5 The air conditioner further includes a fan assembly 10. The fan assembly 10 includes a fan housing 11 and an air guiding device 12 disposed within the fan housing 11. The fan housing 11 has an adjacent fresh air inlet 13 and a humidification air inlet 14. Among them, the filter screen 40 is disposed between the fresh air inlet 13 and the humidification air inlet 14. The first side 410 of the filter screen 40 is adjacent to the fresh air inlet 13, and the second side 420 is adjacent to the humidification air inlet 14.

[0100] In the above embodiment, when fresh air is introduced through the fresh air inlet 13, since the first filtering structure 411 on the first side 410 of the filter screen body 400 has a relatively small filtering resistance, the fresh air can pass through the filter screen 40 to the second side 420 to achieve fresh air function filtering; when humidified air is introduced through the humidification air inlet 14, since the second filtering structure 421 on the second side 420 of the filter screen body 400 has a relatively large filtering resistance, the humidified air is not easily introduced into the filter screen 40, so as to achieve the purpose of reducing the entry of moist air on the humidification side into the filter screen 40.

[0101] In some embodiments of the present application, for example, in an embodiment where the first filtering structure 411 is a first filtering channel 4111 and the second filtering structure 421 is a second filtering channel 4211, the fresh air inlet 13 is located at one end of the first filtering channel 4111 on the first side 410, and the humidification air inlet 14 is located on one side of the second filtering channel 4211 on the second side 420.

[0102] In the above embodiment, when fresh air is introduced through the fresh air inlet 13, since the fresh air inlet 13 is located at one end of the first filtering channel 4111 on the first side 410, the fresh air can smoothly enter the first filtering channel 4111, thereby achieving the purpose of reducing the filtering resistance of the first filtering structure 411; when humidified air is introduced through the humidification air inlet 14, since the humidification air inlet 14 is located on one side of the second filtering channel 4211, the humidified air is not easily introduced into the second filtering channel 4211, so as to achieve the purpose of reducing the entry of moist air on the humidification side into the filter screen 40.

[0103] Specifically, the fresh air inlet 13 and the humidification air inlet 14 are located at the same end of the filter screen 40. For example, refer to Figure 5 , both the fresh air inlet 13 and the humidification air inlet 14 are at the lower end of the filter screen 40. The fresh air and the humidified air both flow from bottom to top. Since the first filtering channel 4111 is arranged to extend in the vertical direction and the second filtering channel 4211 is arranged to extend in the horizontal direction, the fresh air can smoothly enter the first filtering channel 4111, while the humidified air is not easily introduced into the second filtering channel 4211.

[0104] In some embodiments of the present application, for example, in the embodiment where the fresh air inlet 13 and the humidification air inlet 14 are located at the same end of the filter net 40, the orthographic projection of the first side surface 410 on the plane where the fresh air inlet 13 is located at least partially coincides with the fresh air inlet 13, and / or the orthographic projection of the second side surface 420 on the plane where the humidification air inlet 14 is located is separated from the humidification air inlet 14.

[0105] In the above embodiment, since the orthographic projection of the first side surface 410 on the plane where the fresh air inlet 13 is located at least partially coincides with the fresh air inlet 13, the first side surface 410 is inclined and arranged above the fresh air inlet 13, and the fresh air can directly pass through the filter net 40 and enter the second side surface 420 to achieve the fresh air filtering function; at the same time, since the orthographic projection of the second side surface 420 on the plane where the humidification air inlet 14 is located is separated from the humidification air inlet 14, that is, the second side surface 420 is not located above the humidification air inlet 14, when the humidified air is blown in from the humidification air inlet 14 from bottom to top, the humidified air is not likely to flow to the second side surface 420 of the filter net 40, thus avoiding the phenomenon that the filter net 40 gets wet and breeds bacteria.

[0106] As an exemplary embodiment in which the orthographic projection of the first side surface 410 on the plane where the fresh air inlet 13 is located at least partially coincides with the fresh air inlet 13, refer to Figure 5 , the fresh air inlet 13 and the humidification air inlet 14 are located at the lower end of the filter net 40, and the upper end of the filter net 40 is inclined towards the side of the fresh air inlet 13, so that the orthographic projection of the first side surface 410 of the filter net 40 on the plane where the fresh air inlet 13 is located at least partially coincides with the fresh air inlet 13.

[0107] It can be understood that when the filter net 40 is in the shape of a cuboid, if the orthographic projection of the first side surface 410 on the plane where the fresh air inlet 13 is located at least partially coincides with the fresh air inlet 13, then the orthographic projection of the corresponding second side surface 420 of the filter net 40 on the plane where the humidification air inlet 14 is located is separated from the humidification air inlet 14. It should be noted that in other embodiments, for example, when the fresh air inlet 13 and the humidification air inlet 14 are located at the upper end of the filter net 40, the lower end of the filter net 40 is inclined towards the side of the fresh air inlet 13, so that the orthographic projection of the first side surface 410 of the filter net 40 on the plane where the fresh air inlet 13 is located at least partially coincides with the fresh air inlet 13.

[0108] Further, in order to increase the air intake of the fan assembly 10 to improve the fresh air function ventilation and the humidifying effect of the humidifying function, the fan housing 11 has an air guiding chamber 15, a first chamber 16 and a second chamber 17 which are respectively located on both sides of the air guiding chamber 15 and communicated with the air guiding chamber 15. The air guiding device 12 is installed in the air guiding chamber 15. The fresh air inlet 13 includes a first fresh air inlet 131 and a second fresh air inlet 132 which are respectively communicated with the first chamber 16 and the second chamber 17. The humidifying air inlet 14 includes a first humidifying air inlet 141 and a second humidifying air inlet 142 which are respectively communicated with the first chamber 16 and the second chamber 17 and are adjacent to the air guiding chamber 15. The filter screen 40 includes a first filter screen 401 and a second filter screen 402. The first filter screen 401 is arranged in the first chamber 16 and located between the first humidifying air inlet 141 and the first fresh air inlet 131. The second filter screen 402 is arranged in the second chamber 17 and located between the second humidifying air inlet 142 and the second fresh air inlet 132.

[0109] When the air conditioner is in the fresh air mode, the air guiding device 12 drives the fresh air to enter the first chamber 16 and the second chamber 17 on both sides of the air guiding chamber 15 from the first fresh air inlet 131 and the second fresh air inlet 132. The fresh air passes through the first filter screen 401 and the second filter screen 402 and enters the air guiding chamber 15, and finally is discharged into the room through the air guiding chamber 15 to realize the fresh air function in the room. When the air conditioner is in the humidifying mode, the air guiding device 12 drives the humidifying air to enter the first chamber 16 and the second chamber 17 on both sides of the air guiding chamber 15 from the first humidifying air inlet 141 and the second humidifying air inlet 142. Since the first humidifying air inlet 141 and the second humidifying air inlet 142 are arranged adjacent to the air guiding chamber 15, the humidifying air directly enters the air guiding chamber 15 and is finally discharged into the room through the air guiding chamber 15 to realize the indoor air humidifying function. Since the air guiding device 12 introduces fresh air and / or humidifying air from both sides during operation, the air intake of the fan assembly 10 is increased, and the ventilation of the fresh air function and the humidifying effect of the humidifying function are improved.

[0110] Specifically, as an exemplary embodiment of forming the air guiding chamber 15, the first chamber 16 and the second chamber 17, refer to Figure 6 , Figure 6Fig. 0 shows a schematic structural diagram of the fan assembly 10 in an embodiment of the present application. Among them, the fan housing 11 includes a first bracket 111, a first volute 112, a second volute 113, and a second bracket 114 that are combined in sequence. The first volute 112 and the second volute 113 form an air induction chamber 15. The first volute 112 and the first bracket 111 form a first chamber 16. The second volute 113 and the second bracket 114 form a second chamber 17. The air induction chamber 15, the first chamber 16, and the second chamber 17 are formed by the combination of the first bracket 111, the first volute 112, the second volute 113, and the second bracket 114, ensuring the assemblability of the fan assembly 10.

[0111] It can be understood that the fan housing 11 can also be combined in other ways to form the air induction chamber 15, the first chamber 16, and the second chamber 17. For example, two housings with the first chamber 16 and the second chamber 17 respectively are docked in the middle to form the air induction chamber 15.

[0112] Furthermore, for the convenience of setting the fresh air inlet 13 and the humidification air inlet 14, continue to refer to Figure 6 , in which, the first fresh air inlet 131 and the second fresh air inlet 132 are respectively arranged at the first bracket 111 and the second bracket 114, and the first humidification air inlet 141 and the second humidification air inlet 142 are respectively arranged at the first volute 112 and the second volute 113. Since the fresh air inlet 13 is arranged at the first bracket 111 and the second bracket 114 on the outer side, and the humidification air inlet 14 is arranged at the first volute 112 and the second volute 113 on the relatively inner side, the moist air entering from the humidification air inlet 14 is not likely to flow to the first filter screen 401 and the second filter screen 402, and further the phenomenon that the filter screen 40 gets wet and water droplets condense at the fresh air inlet 13.

[0113] Furthermore, for the convenience of forming humidified air and introducing fresh outdoor air, the air conditioner further includes a duct assembly 20. The duct assembly 20 includes a duct housing 21 and a humidifying device 22. The duct housing 21 has a fresh air duct 2121 and a humidifying duct 2122. The humidifying device 22 is arranged at the humidifying duct 2122. The fresh air duct 2121 is docked with the fresh air inlet 13, and the humidifying duct 2122 is docked with the humidification air inlet 14; the fresh air duct 2121 includes a first fresh air duct 210 corresponding to the first chamber 16 and a second fresh air duct 220 corresponding to the second chamber 17, and the humidifying duct 2122 includes a first humidifying duct 230 corresponding to the first chamber 16 and a second humidifying duct 240 corresponding to the second chamber 17.

[0114] The air duct assembly 20 is used to provide a fresh air duct and a humidified air duct for the fan, so that the fan assembly 10 can introduce fresh air and / or humidified air through the air duct assembly 20. Among them, the air duct assembly 20 includes an air duct housing 21 and a humidifying device 22. The air duct housing 21 has a fresh air channel 2121 and a humidifying channel 2122. The humidifying device 22 is arranged at the humidifying channel 2122. The fresh air channel 2121 is docked with the fresh air inlet 13, and the humidifying channel 2122 is docked with the humidifying inlet 14.

[0115] When the air induction device 12 works, the fresh air in the fresh air channel 2121 or the humidified air in the humidifying channel 2122 enters the air induction chamber 15 through the fresh air inlet 13 and the humidifying inlet 14, and then is blown into the room through the outlet to realize the fresh air or humidifying function. Exemplarily, the humidifying device 22 can be a wet film or other devices that can humidify air, such as a sprayer or a vibrating atomizer, etc.

[0116] Further, corresponding to the fan assembly 10 having a first chamber 16 and a second chamber 17, in order to increase the air intake of the fan assembly 10 by introducing fresh air and / or humidified air from both sides, the fresh air channel 2121 includes a first fresh air channel 210 corresponding to the first chamber 16 and a second fresh air channel 220 corresponding to the second chamber 17; the humidifying channel 2122 includes a first humidifying channel 230 corresponding to the first chamber 16 and a second humidifying channel 240 corresponding to the second chamber 17. When the air induction device 12 works, fresh air is simultaneously sucked into the air induction chamber 15 from the first fresh air channel 210 and the second fresh air channel 220, and the humidified gas is simultaneously sucked into the air induction chamber 15 from the first humidifying channel 230 and the second humidifying channel 240, thereby increasing the air intake of the fan assembly 10 and improving the fresh air function ventilation and the humidifying effect of the humidifying function.

[0117] Specifically, as an exemplary embodiment of forming the first humidifying channel 230 and the second humidifying channel 240 corresponding to the second chamber 17 to realize the introduction of humidified air from both sides, refer to Figure 7 , Figure 7FIG. 0 shows a schematic structural diagram of an air duct assembly 20 according to an embodiment of the present application. Among them, the air duct housing 21 includes a water tank 211 and a water tank base 212. The water tank 211 is provided with a humidification air inlet 250. The humidification device 22 includes a first wet film 221 and a second wet film 222. The first wet film 221, the second wet film 222, the water tank 211 and the water tank base 212 enclose to form a humidification air inlet passage 260. The first humidification passage 230 and the second humidification passage 240 are respectively arranged on the sides of the first wet film 221 and the second wet film 222 facing away from the humidification air inlet passage 260, so that after the air enters the humidification air inlet passage 260 through the humidification air inlet 250, it passes through the first wet film 221 and the second wet film 222 and enters the first humidification passage 230 and the second humidification passage 240 on both sides of the humidification air inlet passage 260.

[0118] In the above embodiment, since the first wet film 221 and the second wet film 222 are arranged on the sides of the first humidification passage 230 and the second humidification passage 240, it can ensure that the first wet film 221 and the second wet film 222 have a large area, and further improve the air intake volume of the humidified air. It can be understood that the first wet film 221 and the second wet film 222 can also be directly arranged inside the first humidification passage 230 and the second humidification passage 240.

[0119] Specifically, as an exemplary embodiment of forming the first fresh air passage 210 and the second fresh air passage 220 to introduce humidified air from both sides, continue to refer to Figure 7 , where the air duct housing 21 further includes a rear housing 213. The rear housing 213 has a fresh air inlet 270. The rear housing 213 is arranged on the side of the water tank 211 facing away from the humidification air inlet 250. The rear housing 213 and the water tank base 212 enclose to form a fresh air inlet passage 280. The first fresh air passage 210 and the second fresh air passage 220 are respectively arranged on the sides of the first humidification passage 230 and the second humidification passage 240 facing away from the humidification air inlet passage 260. The water tank base 212 has a partition 23 that separates the humidification air inlet passage 260 from the fresh air inlet passage 280, so that after the air enters the fresh air inlet passage 280 through the fresh air inlet 270, it is guided by the partition 23 and enters the first fresh air passage 210 and the second fresh air passage 220 on both sides of the fresh air inlet passage 280.

[0120] In the above embodiment, since the first fresh air passage 210 and the second fresh air passage 220 are respectively arranged on the sides of the first humidification passage 230 and the second humidification passage 240 facing away from the humidification air inlet passage 260, the air duct assembly 20 forms a double-channel humidification passage 2122 and a fresh air passage 2121 on both sides respectively. At the same time, the humidification air inlet 250 and the fresh air inlet 270 are respectively arranged on the front and back sides. While improving the air intake volume of the fresh air and the humidified air, the overall structure of the air duct assembly 20 is compact, which is beneficial to reducing the overall volume of the air conditioner.

[0121] In order to further reduce the overall volume of the air duct assembly 20 and improve the assembly reliability of the air duct assembly 20, refer to Figure 7 and Figure 8 , Figure 8 shows a schematic structural diagram of a water tank base 212 in an embodiment of the present application. Among them, the air duct housing 21 further includes a first side plate 24 and a second side plate 25 respectively connected to both sides of the water tank base 212. A bottom plate 26 is connected to one side of the first side plate 24 and the second side plate 25 relative to the water tank base 212. The water tank base 212, the first side plate 24, the second side plate 25, and the bottom plate 26 enclose an installation cavity 27, and the water tank 211 is installed in the installation cavity 27, so that the water tank base 212 and the water tank 211 form a compact assembly, and at the same time improve the assembly reliability of the water tank base 212 and the water tank 211.

[0122] It should be noted that the above-mentioned partial embodiments mainly provide an exemplary structure of the air duct assembly 20 for increasing the air intake of fresh air and humidified air and ensuring the overall structural compactness of the air duct assembly 20. Those skilled in the art can make equivalent design changes in the specific implementation manners under the guidance of the present application. For example, a housing with four channels, where wet membranes are arranged in two channels to humidify the air, and the other two channels are connected to the outside to achieve the fresh air function.

[0123] Furthermore, in order to facilitate the switching between the fresh air mode and / or the humidification mode, refer to Figure 5 , the air conditioner further includes a switching assembly 30. The switching assembly 30 includes a driving mechanism 31 and a blocking plate 32. The driving mechanism 31 is used to drive the blocking plate 32 to control the connection or disconnection between the fresh air inlet 13 and the fresh air channel 2121, and to control the connection or disconnection between the humidification inlet 14 and the humidification channel 2122.

[0124] The switching assembly 30 is used to control the start and stop of the fresh air mode and / or the humidification mode. Among them, the switching assembly 30 includes a driving mechanism 31 and a blocking plate 32. The driving mechanism 31 is used to control the connection or disconnection between the fresh air inlet 13 and the fresh air channel 2121, and to control the connection or disconnection between the humidification inlet 14 and the humidification channel 2122, so as to achieve the start and stop of the fresh air mode and / or the humidification mode.

[0125] In some embodiments of the present application, the switching component 30 can be disposed in the air duct component 20, for example, in the fresh air channel 2121 and the humidification channel 2122, and then directly control the opening and closing of the fresh air channel 2121 and the humidification channel 2122 through the driving mechanism 31. In some other embodiments of the present application, the switching component 30 can also be disposed in the fan component 10, for example, at the fresh air inlet 13 and the humidification inlet 14, and then directly control the opening and closing of the fresh air inlet 13 and the humidification inlet 14.

[0126] In order to prevent the switching component 30 from being exposed to humid air and shortening its service life, as a preferred method, refer to Figure 5 as well as Figure 9 , Figure 9 A schematic diagram of the structure of the switching assembly 30 in the embodiment of the present application is shown, wherein the switching assembly 30 is installed between the fan assembly 10 and the air duct assembly 20, the driving mechanism 31 includes a motor 311 and a gear 312 connected to the motor 311, and a rack 321 meshing with the gear 312 is provided on the side of the blocking plate 32 away from the air duct assembly 20. Specifically, the transmission connection with the motor 311 can be through the gear 312 transmission, belt transmission or chain transmission to ensure that the gear 312 can be driven by the motor 311. It can be understood that the gear 312 can also be directly set on the rotating shaft of the motor 311. In the above embodiment, the motor 311 is started to make the gear 312 rotate forward and reverse, thereby making the blocking plate 32 with the rack 321 translate, opening and closing the fresh air channel 2121 and the humidification channel 2122, and realizing the start and close of the fresh air mode and / or the humidification mode. At the same time, since the switching component 30 is installed between the fan component 10 and the air duct component 20, the driving mechanism 31 (for example, the motor 311 part) can be as Figure 4 It is shown that it is arranged outside, so as to prevent the motor 311 from being affected by the humidified air and thus shortening its service life.

[0127] It is worth noting that the above-mentioned embodiment provides an exemplary structure of a switching component 30. Those skilled in the art can make equivalent design changes in the specific implementation method under the guidance of this application. For example, the switching component 30 drives the baffle plate 32 to rotate through the motor 311. When the baffle plate 32 rotates to a horizontal state, the humidification channel 2122 and the fresh air channel 2121 are closed. When the baffle plate 32 rotates to a vertical state, the humidification channel 2122 and the fresh air channel 2121 are opened.

[0128] Further, in order to facilitate the switching between fresh air mode and humidification mode, refer to Figure 10 as well as Figure 11 , Figure 10 A schematic diagram showing a state in which the blocking plate 32 in the embodiment of the present application is in the first working position is shown.Figure 11 FIG. Figure 11 shows a schematic diagram of a state of the air conditioner in the fresh air mode according to an embodiment of the present application. Among them, the baffle 32 has a first working position. When the baffle 32 is in the first working position, the baffle 32 covers the humidification channel 2122, so that the fresh air channel 2121 is opened and the humidification channel 2122 is closed. Air enters the fresh air inlet channel 280 through the fresh air inlet 270, then passes through the fresh air channel 2121, passes through the fresh air outlet 13 through the filter screen, and is sucked into the fan housing 11 by the air guiding device 12, and finally is blown into the room through the outlet of the fan housing 11 to realize the fresh air function.

[0129] Continue to refer to Figure 12 and Figure 13 , Figure 12 FIG. Figure 12 shows a schematic diagram of a state of the baffle 32 in the second working position according to an embodiment of the present application. Figure 13 FIG. Figure 13 shows a schematic diagram of a state of the air conditioner in the humidification mode according to an embodiment of the present application. Among them, the baffle 32 also has a second working position. When the baffle 32 is in the second working position, the baffle 32 covers the fresh air channel 2121, so that the humidification channel 2122 is opened and the fresh air channel 2121 is closed. Air enters the humidification inlet channel 260 through the humidification inlet 250, then passes through the humidification channel 2122, passes through the fresh air outlet 13, and is sucked into the fan housing 11 by the air guiding device 12, and finally is blown into the room through the outlet of the fan housing 11 to realize the air humidification function.

[0130] It can be understood that, in order to simultaneously realize the fresh air and air humidification functions, refer to Figure 14 and Figure 15 , Figure 14 FIG. Figure 14 shows a schematic diagram of a state of the baffle 32 in the third working position according to an embodiment of the present application. Figure 15 FIG. Figure 15 shows a schematic diagram of a state of the air conditioner in the fresh air and humidification modes according to an embodiment of the present application. Among them, the baffle 32 can also have a third working position. When the baffle 32 is in the third working position, the baffle 32 is not located at the fresh air channel 2121 or the humidification channel 2122, so that the fresh air channel 2121 and the humidification channel 2122 are opened simultaneously to simultaneously realize the fresh air and air humidification functions.

[0131] When the fresh air and humidification modes are simultaneously turned on, since the fresh air channel 2121 and the fresh air outlet 13, and the humidification channel 2122 and the humidification outlet 14 are independent of each other, it is possible to avoid the phenomenon that the fresh air and humidification air inlet resistance is too large due to the series arrangement of the filter screen for fresh air and the humidification device for humidification air, etc., and finally the indoor air renewal is slow.

[0132] It should be noted that the above description of the air conditioner is only for clearly explaining the verification process of this application. Those skilled in the art can make equivalent modification designs to the above air conditioner under the guidance of this application. For example, the baffle 32 can also close the fresh air channel 2121 and the humidification channel 2122 simultaneously to ensure the tightness of the fan assembly 10 when the air conditioner stops running.
