[0038] Combination Figure 1-7 As shown, in some embodiments, the humidifying air conditioner includes: a housing 100 and a wet film humidifying device 200. A heat exchange air duct 101 is provided inside the housing 100; the wet film humidifying device 200 is arranged inside the housing 100 and has an air inlet 201; wherein the air inlet 201 of the wet film humidifying device 200 is communicated with the heat exchange air duct 101, so that part of the heat exchange air flow in the heat exchange air duct 101 flows to the air inlet 201 of the wet film humidifying device 200.

[0039] The humidifying air conditioner provided by the embodiment of the present disclosure is adopted, by introducing part of the heat exchange airflow in the heat exchange air duct 101 into the air inlet 201 of the wet film humidifying device 200, because the wet film humidifying device 200 humidifies by accelerating the evaporation of water by the incoming airflow, the evaporation amount of water is related to the temperature of the incoming airflow. The heat exchange airflow in the heat exchange air duct 101 is introduced into the wet film humidifying device 200, and the temperature of the heat exchange airflow is used to accelerate the evaporation of water, increase the evaporation amount of the wet film humidifying device 200, and thus improve the humidification effect of the humidifying air conditioner.

By respectively providing the first air outlet 102 and the second air outlet 103 on the side wall of the shell 100 to blow out the heat exchange airflow and the humidified airflow respectively, the heat exchange airflow and the humidified airflow are mixed after being blown out of the shell 100, thereby improving the humidification effect.

[0041] Optionally, the first air outlet 102 and the second air outlet 103 are arranged side by side. In this way, the heat exchange airflow blown out of the first air outlet 102 and the humidified airflow blown out of the second air outlet 103 can be blown out into the environment side by side, and the heat exchange airflow and the humidified airflow can be mixed more evenly, thereby improving the humidification effect.

[0042] Optionally, the first air outlet 102 and the second air outlet 103 are both vertically opened on the side wall of the housing 100 , and the first air outlet 102 is located on one side of the second air outlet 103 in the horizontal direction.

[0043] Optionally, the first air outlet 102 and the second air outlet 103 are both long strip-shaped structures. In this way, the first air outlet 102 and the second air outlet 103 both form a vertical long strip air outlet area, so that the blown heat exchange airflow and humidification airflow are better mixed, thereby improving the humidification effect.

[0044] Optionally, in the vertical direction, the outlet height of the first air outlet 102 is the same as the outlet height of the second air outlet 103. In this way, the outlet heights of the heat exchange airflow blown out of the first air outlet 102 and the humidified airflow blown out of the second air outlet 103 are the same, and the heat exchange airflow and the humidified airflow can be mixed more evenly in the environment, thereby improving the humidification effect.

[0045] Optionally, the upper edge of the first air outlet 102 and the upper edge of the second air outlet 103 are located on the same horizontal line, and the lower edge of the first air outlet 102 and the lower edge of the second air outlet 103 are located on the same horizontal line. In this way, the upper and lower heights of the air outlet area of ​​the first air outlet 102 and the air outlet area of ​​the second air outlet 103 are the same, and the blown heat exchange airflow and humidification airflow can be mixed more evenly, thereby improving the humidification effect.

[0046] Optionally, the housing 100 includes: a first housing 110, a second housing 120 and a third housing 130. A base 300 is provided inside the first housing 110, and the wet film humidifying device 200 is installed inside the base 300; the second housing 120 is arranged on the upper side wall of the first housing 110, and the heat exchange air duct 101 is arranged inside the second housing 120; the third housing 130 is arranged on the upper side wall of the first housing 110, and is arranged side by side with the second housing 120, and a humidifying air flow channel 131 is defined inside the third housing 130, and the air outlet end of the wet film humidifying device 200 is connected to the humidifying air flow channel 131. In this way, the shell 100 is divided into a first shell part 110, a second shell part 120 and a third shell part 130, a base 300 is arranged inside the first shell 100 to install the wet film humidification device 200, a heat exchange air duct 101 is arranged inside the second shell 100, and a humidification air flow channel 131 is arranged inside the second shell 100, so that the operation of the wet film humidification device 200, the circulation of the heat exchange air flow and the circulation of the humidification air flow do not affect each other, thereby improving the working stability of the humidification air conditioner. The second shell part 120 and the third shell part 130 are arranged side by side, so that the heat exchange air flow blown out of the heat exchange air duct 101 and the humidification air flow blown out of the humidification air flow channel 131 can be better mixed, thereby improving the humidification effect.

[0047] Optionally, the first air outlet 102 is vertically opened on the side wall of the second shell portion 120 , and the second air outlet 103 is vertically opened on the side wall of the third shell portion 130 .

[0048] Optionally, in the vertical direction, the second shell 120 and the third shell 130 have the same height. In this way, the first air outlet 102 on the side wall of the second shell 120 and the second air outlet 103 on the side wall of the third shell 130 are conveniently opened, and the overall shape of the humidifying air conditioner is more regular.

[0049] Optionally, there is a gap between the second shell 120 and the third shell 130 in the horizontal direction. In this way, the heat exchange between the heat exchange air duct 101 in the second shell 120 and the humidification air flow channel 131 in the third shell 130 can be reduced, and the influence of the temperature between the heat exchange air duct 101 and the humidification air flow channel 131 can be reduced.

[0050] Optionally, the upper side wall of the second shell portion 120 is connected to the upper side wall of the third shell portion 130 via a connecting plate. In this way, the stability between the second shell portion 120 and the third shell portion 130 can be enhanced.

[0051] Optionally, the wet film humidifying device 200 is detachably connected to the base 300, and a maintenance door is provided at a position of the side wall of the first shell 110 corresponding to the wet film humidifying device 200, and the maintenance door is rotatably connected to the side wall of the first shell 110. In this way, the disassembly and maintenance of the wet film humidifying device 200 is facilitated. When the wet film humidifying device 200 needs to be disassembled, the maintenance door is opened to open the internal space of the first shell 110, and then the wet film humidifying device 200 is disassembled.

[0052] Optionally, a maintenance port is provided on the side wall of the first shell 110 corresponding to the position of the wet film humidifying device 200, and one side of the maintenance door is rotatably connected to one side of the maintenance port, and the maintenance port is opened or closed through the maintenance door. In this way, when the wet film humidifying device 200 needs to be disassembled, the maintenance door is opened and disassembled through the maintenance port.

[0053] Combination Figure 3 and Figure 4 As shown, in one embodiment, a water receiving tray 121 is provided at the bottom of the second shell 120, and a drainage nozzle is provided at the bottom of the water receiving tray 121, which is communicated with the water tank 280 of the wet film humidifying device 200. In this way, since the heat exchange air duct 101 is provided inside the second shell 120, condensed water may be generated in the heat exchange air duct 101 when the humidifying air conditioner is cooling, so the water receiving tray 121 is provided at the bottom of the second shell 120, and the water receiving tray 121 is used to receive the condensed water generated during cooling, and the generated condensed water is guided to the water tank 280 of the wet film humidifying device 200 for humidification, so that the condensed water is reused, the humidification cost is reduced, and the user experience is improved.

[0054] Optionally, the drain nozzle is connected to the water tank 280 through the conduit 122 .

[0055] Optionally, the water receiving tray 121 is located below the heat exchange air duct 101, and a heat exchanger is arranged in the heat exchange air duct 101. In this way, the heat exchange airflow in the heat exchange air duct 101 is blown out after exchanging heat with the heat exchanger, and when the heat exchanger is used as an evaporator for cooling, condensed water condensed on the heat exchanger can drip into the water receiving tray 121 and be guided to the water tank 280 of the wet film humidification device 200.

[0056] Optionally, a return air port is provided on the rear side wall of the second shell portion 120 , and air flow in the environment flows into the heat exchange air duct 101 through the return air port and is blown out from the first air outlet 102 after exchanging heat with the heat exchanger.

[0057] Optionally, the humidifying air conditioner further includes: an air duct 400. One end of the air duct 400 extends into the heat exchange air duct 101, and the other end extends into the air inlet 201 of the wet film humidifying device 200. The heat exchange air duct 101 is connected to the air inlet 201 through the air duct 400. In this way, part of the heat exchange airflow in the heat exchange air duct 101 is guided to the air inlet 201 of the wet film humidifying device 200 through the air duct 400, and the temperature of the heat exchange airflow is used to accelerate the evaporation of water in the wet film humidifying device 200, thereby improving the humidification effect.

[0058] It is understandable that when the humidifying air conditioner is heating in the cold winter, the environment is relatively dry. At this time, the wet film humidifying device 200 works to humidify. Therefore, the heat exchange air flow introduced through the air duct 400 is a hot air flow. The hot air flow guided to the air inlet 201 of the wet film humidifying device 200 can accelerate the evaporation of water in the wet film humidifying device 200 and improve the humidification effect.

[0059] Optionally, a valve is provided in the air duct 400. When the humidifying air conditioner is operated in the cooling mode, the valve is closed, and when the humidifying air conditioner is operated in the heating mode, the valve is opened. In this way, when the environment is cooled, humidification is not required, so the valve in the air duct 400 is closed to prevent the cold air flow in the heat exchange air duct 101 from being guided to the air inlet 201, thereby reducing the loss of the heat exchange air flow. When the environment is heated, humidification is required, so the valve in the air duct 400 is opened, and part of the hot air flow is guided to the air inlet 201 through the air duct 400.

[0060] Optionally, the air inlet end of the air duct 400 extends into the heat exchange air duct 101 and is located at the air outlet side of the heat exchanger. In this way, the airflow guided by the air duct 400 is the airflow after heat exchange, ensuring the humidification effect of the wet film humidification device 200.

[0061] Optionally, a supplementary air port is provided on the side wall of the first shell 110 at a position corresponding to the air inlet 201. In this way, since the air flow guided by the air duct 400 is limited, and the air flow required by the wet film humidification device 200 during humidification is relatively large, the supplementary air port is provided on the side wall of the first shell 110 to supplement the air flow in the environment to flow into the air inlet 201, thereby ensuring the air intake of the wet film humidification device 200 and thus ensuring the humidification effect of the wet film humidification device 200.

[0062] Combination Figure 5-Figure 7As shown, in some embodiments, the wet film humidification device 200 includes: a box body 210 and a wet film 220. A normal temperature water tank 211 is provided on the lower inner wall of the box body 210; the wet film 220 is provided in the box body 210, and the lower end of the wet film 220 is soaked in the normal temperature water tank 211; wherein, the air inlet 201 is provided on the side wall of the box body 210, and the air flow flowing into the air inlet 201 passes through the wet film 220 and then flows out. In this way, the wet film 220 absorbs the water in the normal temperature water tank 211, and the air flow flows into the box body 210 from the air inlet 201 and passes through the wet film 220, so that the moisture in the wet film 220 evaporates, and the evaporated moisture is blown out from the second air outlet 103 along with the air flow, so as to humidify the environment. Humidification is performed by evaporating moisture through the wet film 220, thereby increasing the humidification amount and improving the humidification effect.

[0063] Optionally, an opening is provided on the upper side wall of the box body 210, and the wet film 220 is installed in the airflow cavity through the opening. In this way, the wet film 220 is installed or removed through the opening, which is convenient for maintenance and replacement of the wet film 220.

[0064] Optionally, an installation space is provided inside the base 300, a guide rail is provided on the inner side wall of the installation space, a slide seat is provided on the outer side wall of the box body 210 at a position corresponding to the guide rail, and the slide seat is slidably embedded in the guide rail, so that the box body 210 can be slidably installed in the installation space. In this way, the box body 210 can be slidably installed in the installation space by using the cooperation of the guide rail and the slide seat, which facilitates the installation and removal of the box body 210, thereby facilitating the installation and removal of the wet film humidification device 200.

[0065] Optionally, a temperature-controlled water tank 212 is further provided on the lower inner wall of the box body 210, and a spraying part 230 is provided on the upper end of the wet film 220. The spraying part 230 is connected to the temperature-controlled water tank 212, and can extract water in the temperature-controlled water tank 212 and spray it to the upper end of the wet film 220. In this way, by providing a normal temperature water tank 211, a temperature-controlled water tank 212 and a spraying part 230, the lower end of the wet film 220 is immersed in the normal temperature water tank 211, and the spraying part 230 can absorb water in the temperature-controlled water tank 212 and spray it to the upper part of the wet film 220. When the spraying part 230 is not working, the lower end of the wet film 220 absorbs normal temperature water for humidification, which can adapt to a humidification environment with a relatively small humidification demand. When the spraying part 230 is working, the lower end of the wet film 220 absorbs normal temperature water, and the upper end of the wet film 220 sprays normal temperature water for humidification, which can adapt to a humidification environment with a relatively moderate humidification demand. When the spraying part 230 is working and the water in the temperature-controlled water tank 212 is temperature-controlled, the lower end of the wet film 220 absorbs normal temperature water, and the upper end of the wet film 220 sprays temperature-controlled water for humidification, which can adapt to a humidification environment with a relatively large humidification demand. The humidifying air conditioner has a humidification mode that can adapt to a variety of humidification demands, can accurately humidify the environment, and improve the user experience.

[0066] Optionally, the wet film 220 is a cylindrical structure, the air inlet side of the wet film 220 is located at the outer peripheral wall in the radial direction, and the air outlet side of the wet film 220 is located at the upper port in the axial direction. In this way, the wet film 220 with a cylindrical structure has a larger evaporation area and occupies less space. The inlet air flow is blown from the air inlet side of the wet film 220 to the outer peripheral wall of the wet film 220, increasing the contact area between the wet film 220 and the inlet air flow, improving the evaporation efficiency of the wet film 220, and the evaporated water vapor is blown out along the axial direction of the wet film 220 together with the air flow.

[0067] Optionally, the wet film 220 is vertically arranged in the box body 210, and the axis of the wet film 220 is perpendicular to the horizontal plane. In this way, the airflow from the air inlet 201 opened on the vertical side wall of the box body 210 can smoothly flow to the outer peripheral wall of the wet film 220, and the airflow passing through the outer peripheral wall of the wet film 220 flows out along the open part through the inner side of the wet film 220, thereby improving the evaporation efficiency of the wet film 220.

[0068] Optionally, the air inlet 201 is provided in the lower area of ​​the outer peripheral wall of the wet film 220 corresponding to the vertical side wall of the box body 210. In this way, the air flow flowing into the air inlet 201 can be blown to the lower area of ​​the outer peripheral wall of the wet film 220, and then gradually contact with most of the outer peripheral wall of the wet film 220 during the process of gradually flowing upward, thereby improving the evaporation effect of the wet film 220.

[0069] Optionally, a centrifugal fan 240 is provided at the open portion, and the air inlet end of the centrifugal fan 240 is arranged toward the upper port of the wet film 220. In this way, by utilizing the characteristics of the centrifugal fan 240 that the air enters axially and exits radially, the negative pressure can be better applied to the inner side of the wet film 220 of the cylindrical structure, and the negative pressure is provided for the air inlet of the wet film 220. Under the action of the centrifugal fan 240, the air inlet airflow flows from multiple directions of the multiple air inlets 201 to the outer peripheral wall of the wet film 220, passes through the outer peripheral wall of the wet film 220 and flows into the inner side of the wet film 220, enters the centrifugal fan 240 through the upper port of the wet film 220, and then blows out from the air outlet end of the centrifugal fan 240. Under the action of the centrifugal fan 240, the air inlet volume of the wet film 220 can be increased, thereby improving the evaporation effect of the wet film 220.
