[0040] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0041] like Figure 1 As shown, this embodiment of the invention provides a humidification device, including an atomizing module 100, a water extraction module 200, and an air outlet module. The atomizing module 100 includes an atomizing box 110 and an atomizer 120, with the atomizer 120 installed inside the atomizing box 110. The atomizing box 110 has an atomizing water inlet 113, an atomizing air inlet, and a mist outlet 114. The water extraction module 200 has a water extraction inlet 222 and a water extraction outlet 232. The water extraction inlet 222 is connected to an external water source, and the water extraction outlet 232 is connected to the atomizing water inlet 113. The air outlet module has a water mist air inlet 301, which is connected to the mist outlet 114.

[0042] It is understandable that the water pumping module 200 is used to pump water from an external water source and deliver it to the atomizing module 100.

[0043] The atomizing module 100 is equipped with an atomizing box 110 and an atomizer 120. The atomizer 120 can atomize the water supplied by the water pumping module 200 into water mist. The water mist fills the atomizing box 110. Driven by the negative pressure formed by the air outlet module, the water mist enters the air outlet module from the mist outlet 114.

[0044] The atomizing box 110 is equipped with an atomizing air inlet. Driven by the negative pressure generated by the air outlet module, outside air enters the atomizing box 110 through the atomizing air inlet and mixes with the water mist generated by the atomizer 120. The larger water droplets in the water mist can clean dust and other impurities in the air and drip down and accumulate inside the atomizing box 110. The cleaned air with higher humidity enters the air outlet module from the mist outlet 114 and is then sent out to the outside by the air outlet module.

[0045] The humidification device provided in this embodiment of the invention can pump water from an external water source to the atomization module 100, atomize the water, and then deliver it to the outside through the air outlet module to increase air humidity. Furthermore, during the atomization process, outside air enters the atomization box 110 through the atomization air inlet, and is cleaned by the water mist within the atomization box 110, forming high-humidity clean air. Therefore, the humidification device provided in this embodiment of the invention can increase the humidity of the outside air while also cleaning the outside air and reducing the content of dust and impurities in the air.

[0046] Based on the above embodiments, optionally, in some embodiments of the present invention, such as Figures 2-5 As shown, the atomizing box 110 is provided with a water storage chamber 111 and an atomizing chamber 112. The atomizing water inlet 113 is located on the wall of the water storage chamber 111, and the atomizing air inlet and mist outlet 114 are located on the wall of the atomizing chamber 112. The atomizer 120 is provided with an inlet 121 and an outlet 122. The inlet 121 is connected to the water storage chamber 111, and the outlet 122 is connected to the atomizing chamber 112.

[0047] It can be understood that the atomizing box 110 is divided into two chambers: a water storage chamber 111 for storing water supplied by the water pumping module 200, and an atomizing chamber 112 for containing water mist. An atomizer 120 is installed on a plate separating the water storage chamber 111 and the atomizing chamber 112. The water storage chamber 111 and the atomizing chamber 112 are connected through the atomizer 120. Water in the water storage chamber 111 enters the atomizer 120 through inlet 121, is atomized, and then enters the atomizing chamber 112 through outlet 122, mixing with air entering the atomizing chamber 112 through the atomizing air inlet. The water mist contained within the atomizing chamber 112 flows into the air outlet module through the mist outlet 114 under the negative pressure generated by the air outlet module.

[0048] The water storage chamber 111 and the atomizing chamber 112 can be divided into left and right sections or into upper and lower sections. For example, Figure 3 and Figure 4As shown, the water storage chamber 111 is located above the atomizing chamber 112, the atomizing water inlet 113 is located on the top wall of the atomizing box 110, and the atomizing air inlet and mist outlet 114 are located on the side wall of the atomizing box 110, within the height range of the atomizing chamber 112. The atomizing box 110 contains a plate that separates the water storage chamber 111 and the atomizing chamber 112, forming the top wall of the atomizing chamber 112 and the bottom wall of the water storage chamber 111. The atomizer 120 is mounted on this plate, with its inlet 121 located in the water storage chamber 111 and its outlet 122 located in the atomizing chamber 112.

[0049] It is worth noting that the terms "up," "down," "left," and "right" are based on... Figure 1 The views shown are the top, bottom, left, and right angles when the humidifier is installed on a wall-mounted air conditioner. And with... Figure 1 The view shown is a frontal view, that is, the long and tall side of the atomizing box 110 is the side view, and the wide and tall side is the front view.

[0050] Based on the above embodiments, optionally, a partition 117 is provided inside the atomizing chamber 112. The partition 117 is connected to the two opposing chamber walls of the atomizing chamber 112 that are parallel to the mist outlet 114. The partition 117 is arranged around the mist outlet 114 and has a gap in the circumference of the mist outlet 114. Under the drive of the air outlet module, the water mist in the atomizing box 110 can flow along the partition 117 to the mist outlet 114.

[0051] For example, such as Figure 3 As shown, the mist outlet 114 is located on one side wall of the atomizing chamber 112. The two sides of the partition 117 are respectively connected to the side walls of the atomizing chamber 112, and the partition 117 is perpendicular to the side walls of the atomizing chamber 112. The starting end of the partition 117 is connected to the rear wall of the atomizing chamber 112 and extends along a curve around the mist outlet 114. The ending end of the partition 117 faces the starting end and has a gap between it and the starting end. Furthermore, the outlet 122 and the atomizing air inlet of the atomizer 120 are both located on the same side as the starting end of the partition 117.

[0052] Thus, the partition 117 divides the cavity space along the width direction of the atomizing cavity 112. The air entering the atomizing cavity 112 through the atomizing air inlet and the water mist generated by the atomizer 120 do not directly diffuse into the entire atomizing cavity 112. Instead, they diffuse from the beginning of the partition 117 along the extension direction of the partition 117 to the end, and then enter the mist outlet 114 through the gap between the beginning and the end. During the water mist diffusion process, the air entering through the atomizing air inlet mixes thoroughly with the water mist generated by the atomizer 120. Larger water droplets in the water mist are washed away after impurities are removed and fall to the partition 117, flowing along the partition 117 to accumulate at the bottom of the atomizing cavity 112.

[0053] The humidification device provided in this embodiment of the invention has a baffle 117 in the atomizing chamber 112 that enhances water mist separation, reduces large water droplets in the water mist, makes the mist finer, and more effectively separates water droplets that clean the air and adsorb dust and impurities in the air, thereby improving the efficiency of air purification.

[0054] Based on the above embodiments, optionally, the water storage chamber 111 is provided with a water level detection element 130, which is communicatively connected to the pumping module 200. The water level detection element 130 is used to detect the water level in the water storage chamber 111, and the pumping module 200 is used to pump water when the water level in the water storage chamber 111 is lower than a first height, and to stop pumping water when the water level in the water storage chamber 111 is higher than a second height.

[0055] It is understandable that the second height is higher than the first height. The water level detection element 130 can be a water level sensor or other electronic components.

[0056] In some embodiments, the water level detection element 130 includes a first magnetic switch 131, a second magnetic switch 132, and a magnetic float 133; the first magnetic switch 131 is installed at a first height on the side wall of the water storage cavity 111, the second magnetic switch 132 is disposed at a second height on the side wall of the water storage cavity 111, and the magnetic float 133 is installed in the water storage cavity 111 and floats with the water level of the water storage cavity 111.

[0057] Specifically, such as Figure 2 and Figure 4 As shown, the first magnetic switch 131 and the second magnetic switch 132 are both installed on the outer wall of the atomizing box 110. The first magnetic switch 131 is located at a first height above the bottom of the water storage chamber 111, and the second magnetic switch 132 is located at a second height above the bottom of the water storage chamber 111. When one of the first magnetic switch 131 and the second magnetic switch 132 is turned on, the other is turned off. The magnetic buoy 133 floats on the water surface in the water storage chamber 111. When the water level in the water storage chamber 111 drops to the first height, the magnetic buoy 133 floats with the water surface at the first height. The magnetic buoy 133 is opposite to the first magnetic switch 131. Under the action of magnetic force, the first magnetic switch 131 is turned on, and the water pumping module 200 starts to pump water from the external water source. The water enters the water storage chamber 111 through the atomizing inlet 113, and the water level in the water storage chamber 111 rises. When the water level in the water storage chamber 111 rises to the second height, the magnetic buoy 133 floats with the water surface at the second height. The magnetic buoy 133 is opposite to the second magnetic switch 132. Under the action of magnetic force, the second magnetic switch 132 is turned on, and the pumping module 200 stops pumping water from the external water source.

[0058] Based on the above embodiments, optionally, the atomizing air inlet includes an atomizing side air inlet 115 and a post-atomizing air inlet 116. The atomizing side air inlet 115 is located on the side wall of the atomizing cavity 112, and the post-atomizing air inlet 116 is located on the wall of the atomizing cavity 112 adjacent to the side wall of the atomizing cavity 112 where the atomizing side air inlet 115 is located.

[0059] For example, such as Figure 2 and Figure 5 As shown, the atomizing side air inlet 115 is located on the side wall of the atomizing chamber 112, and the post-atomizing air inlet 116 is located on the rear wall of the atomizing chamber 112. The terms "side" and "rear" are based on... Figure 1 The frontal viewpoint shown is determined.

[0060] Based on the above embodiments, optionally, the atomizer 120 is an ionization atomizer, which is used to generate water mist carrying an electric charge. Thus, after outside air enters the atomization chamber 112 through the atomization inlet, dust and impurities in the air are electrostatically adsorbed by the water mist, improving the air purification effect.

[0061] Based on the above embodiments, optionally, such as Figures 6-8 As shown, the pumping module 200 includes a hollow rotating shaft 210, a pumping pipe 220, a water delivery pipe 230, a water pump 240, and a drive mechanism. The hollow rotating shaft 210 is provided with a rotating shaft inlet 211 and a rotating shaft outlet 212; the water pump 220 is partially wound around the hollow rotating shaft 210, one end of the water pump 220 is connected to the rotating shaft inlet 211, and the other end of the water pump 220 is suspended and is provided with a water pump inlet 222. The water pump 220 can be lowered or wound back onto the hollow rotating shaft 210 as the hollow rotating shaft 210 rotates; one end of the water delivery pipe 230 is connected to the rotating shaft outlet 212, and the other end of the water delivery pipe 230 is provided with a water pump outlet 232; the water pump 240 is connected to the water delivery pipe 230; the drive mechanism is connected to the hollow rotating shaft 210 for transmission, and the drive mechanism is used to drive the hollow rotating shaft 210 to rotate so that the suspended end of the water pump 220 is lowered or retracted, so that the water pump inlet 222 is connected to or separated from an external water source.

[0062] like Figure 7 As shown, the inlet 211 and outlet 212 of the rotating shaft are respectively located at both ends of the hollow rotating shaft 210. One end of the suction pipe 220 is the suction pipe inlet 221, and the other end is the suction inlet 222. The suction pipe inlet 221 is connected to the inlet 211, and the suction pipe 220 coils around the hollow rotating shaft 210 from the inlet 211, with the remaining portion suspended below the hollow rotating shaft 210. Figure 6As shown, the hollow shaft 210 can rotate under the drive of the drive mechanism. As the hollow shaft 210 rotates, the water pumping pipe 220 extends downward from the hollow shaft 210 one turn at a time, so that the water pumping inlet 222 can be inserted into an external water source, or can be wound back into the hollow shaft 210 one turn at a time, so that the water pumping inlet 222 is detached from the external water source.

[0063] like Figure 8 As shown, one end of the water supply pipe 230 is a water supply port 231, and the other end is a water outlet 232. The water outlet 232 is connected to the atomizing water inlet 113. The water supply port 231 can be directly connected to the rotating shaft outlet 212, or, as... Figure 6 and Figure 7 As shown, the water outlet 212 of the rotating shaft is connected to the receiving cavity 213, and the bottom of the receiving cavity 213 is provided with a receiving cavity opening 214, and the water supply pipe 231 is connected to the receiving cavity opening 214.

[0064] The water pump 240 is installed on the water supply pipe 230. When the water inlet 222 is inserted into the external water source, the water from the external water source enters the atomizing box 110 through the water pump 240, the water in the external water source in sequence through the water pump 220, the hollow rotating shaft 210 and the water supply pipe 230.

[0065] It is understandable that the operating status of the water pump 240 and the drive mechanism can be determined based on the water level detection element 130 in the atomization module 100.

[0066] Based on the above embodiments, optionally, the drive mechanism includes a first gear set. The first gear set includes a driving gear 252 and a driven gear 253, the driving gear 252 and the driven gear 253 are engaged in transmission, and the hollow rotating shaft 210 is coaxially and fixedly connected to the driven gear 253.

[0067] like Figure 6 and Figure 7 As shown, the driving gear 252 is mounted on the output shaft of the first motor 251 and rotates under the drive of the first motor 251. The driven gear 253 meshes with the driving gear 252 and rotates under the drive of the driving gear 252. The driven gear 253 is fixedly mounted on the first gear shaft. The first gear shaft and the hollow rotating shaft 210 are coaxially and fixedly connected end to end, or the first gear shaft is composed of a part of the hollow rotating shaft 210. Thus, under the drive of the driven gear 253, the hollow rotating shaft 210 rotates clockwise or counterclockwise, allowing the water pipe 220 to extend into or retract into the hollow rotating shaft 210.

[0068] Further optional, such as Figure 6As shown, the driving mechanism also includes a rotating clamping member 255. The circumferential sidewall of the rotating clamping member 255 is provided with an annular groove. One of the suspended ends of the water pumping pipe 220 is accommodated in the annular groove along the tangent of the annular groove. When rotating, the rotating clamping member 255 can drag the suspended end of the water pumping pipe 220 to lower or retract it.

[0069] In one embodiment, such as Figure 6 As shown, the rotating clamp 255 includes two parallel gears spaced apart from each other. The two parallel gears are coaxially connected and rotate synchronously. The portion of the water pump 220 extending out of the hollow rotating shaft 210 is clamped between the two parallel gears.

[0070] It can be understood that two parallel gears are spaced apart and fitted onto the second gear shaft, with the parallel gears fixedly connected to the second gear shaft. Thus, the two parallel gears and the second gear shaft together form an "I"-shaped gear set, and the opposing tooth surfaces of the two parallel gears and the second gear shaft together form an annular groove. The portion of the water suction pipe 220 extending from the hollow rotating shaft 210 can be interference-fitted into the annular groove, with the pipe wall of the water suction pipe 220 pressing against the tooth surfaces of the parallel gears. When the first motor 251 drives the hollow rotating shaft 210 to rotate, and the portion of the water suction pipe 220 extending from the hollow rotating shaft 210 moves downwards or upwards, the second motor 254 drives the rotating clamping member 255 to rotate, thereby synchronously causing the tooth surfaces of the parallel gears to move the pipe wall of the water suction pipe 220 downwards or upwards. The rotating clamping member 255 assists the first gear set in driving the movement of the water suction pipe 220, and also guides the portion of the water suction pipe 220 extending from the hollow rotating shaft 210.

[0071] Optionally, based on the above embodiments, the air outlet module is a centrifugal fan 300.

[0072] On the other hand, such as Figure 1 , Figure 9 and Figure 10 As shown, the present invention also provides a wall-mounted air conditioner, including a housing 500, a cross-flow fan 400, and a humidification device provided in any of the above embodiments, wherein the air outlet module of the humidification device is a centrifugal fan 300. The cross-flow fan 400 is installed inside the housing 500, and the humidification device is installed at one end of the cross-flow fan 400.

[0073] It can be understood that the air inlet of the centrifugal fan 300 is the water mist inlet 301, and the air outlet of the centrifugal fan 300 is the water mist outlet 302. The water mist inlet 301 is located at the central axis of the centrifugal fan 300, and the water mist outlet 302 faces radially outward from the centrifugal fan 300. Figure 1 As shown, the atomizing module 100 is connected to the centrifugal fan 300, so that the mist outlet 114 is connected to the water mist inlet 301.

[0074] The external water source can be a water tank installed below the wall-mounted air conditioner, with water added manually by the user. Alternatively, the wall-mounted air conditioner can have a condensate recovery device that collects the condensate and directs it into the water tank. Or, the outer casing 500 can have an opening that matches the drain pipe 220, which extends directly to the outside of the wall-mounted air conditioner. The user can place a basin or bucket under the drain pipe 220 as an external water source.

[0075] The wall-mounted air conditioner provided in this embodiment of the invention includes a humidification device, which has the functions of humidifying and purifying air. The air outlet module of the humidification device is a centrifugal fan 300. The axial distance between the water mist inlet 301 and the water mist outlet 302 of the centrifugal fan 300 is small. Therefore, the humidification device is installed at one end of the cross-flow fan 400, which occupies a small installation space and will not affect the normal air outlet of the wall-mounted air conditioner. It also enables the wall-mounted air conditioner to have the functions of humidifying and purifying indoor air at the same time.

[0076] Based on the above embodiments, optionally, the centrifugal fan 300 and the cross-flow fan 400 are coaxially connected, and the cross-flow fan 400 can drive the centrifugal fan 300 to rotate synchronously.

[0077] like Figure 1 and Figure 9 As shown, the centrifugal fan 300 and the cross-flow fan 400 are coaxially fixedly connected. The fan motor drives the cross-flow fan 400 to rotate, and the cross-flow fan 400 drives the centrifugal fan 300 to rotate. Thus, the humidification device does not need to be set to start the motor separately, and can humidify and clean the air simultaneously when the air conditioner is cooling or heating normally.

[0078] Based on the above embodiments, optionally, such as Figure 9 and Figure 10 As shown, the outer casing 500 is provided with an air inlet grille 501, which is opposite to the cross-flow fan 400, and the air outlet of the centrifugal fan 300 faces the side where the air inlet grille 501 is located.

[0079] It is understandable that the outer casing 500 of the wall-mounted air conditioner is equipped with an air duct, which includes an air inlet grille 501 and an air outlet 502. The air inlet grille 501 is located above the cross-flow fan 400, and the air outlet 502 is located below the cross-flow fan 400. Outside air enters the air duct through the air inlet grille 501, and after heat exchange with the heat exchanger driven by the cross-flow fan 400, it is discharged back into the outside through the air outlet 502, thus completing the normal cooling and heating function of the wall-mounted air conditioner.

[0080] The air outlet of the centrifugal fan 300, namely the water mist outlet 302, faces the side where the air inlet grille 501 is located, that is, the water mist outlet 302 faces the top of the wall-mounted air conditioner. It can be understood that the outer casing 500 also has an opening on one side of the air inlet grille 501 that matches the water mist outlet 302, so that the clean, high-humidity air generated by the humidification device is discharged to the outside from the water mist outlet 302 and is located near the air inlet grille 501 of the air conditioner. Driven by the cross-flow fan 400, it enters the air duct of the outer casing 500 along with other outside air.

[0081] The wall-mounted air conditioner provided by this invention has a water mist outlet 302 facing the side where the air inlet grille 501 of the wall-mounted air conditioner is located. The clean and humid air generated is then drawn back into the air inlet grille 501. This increases indoor humidity and reduces the content of impurities in indoor air while maintaining a stable outlet temperature, making it less likely to reduce the cooling or heating effect of the air conditioner.

[0082] Based on the above embodiments, optionally, the outer casing 500 is provided with a humidifying air inlet 503, which is opposite to the atomizing air inlet.

[0083] for example, Figure 10 This is a schematic diagram of the rear view of a wall-mounted air conditioner with the outer casing removed (500mm rear wall section). Figure 10 As shown, the atomizing air inlet includes an atomizing side air inlet 115 and a post-atomizing air inlet 116. A humidifying air inlet 503 is provided on the side wall of the outer casing 500, opposite to the atomizing side air inlet 115, facilitating the entry of outside air into the atomizing box 110 through the humidifying air inlet 503 and the atomizing side air inlet 115. Optionally, a humidifying air inlet 503 (not shown in the figure) is also provided on the rear wall of the outer casing 500, opposite to the post-atomizing air inlet 116.

[0084] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
