[0050] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of the present invention and are not intended to limit the scope of protection of the present invention. Those skilled in the art may adjust them as needed to suit specific applications.

[0051] Secondly, it should be noted that in the description of the present invention, terms such as "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present invention.

[0052] Furthermore, it should be noted that, in the description of the present invention, unless otherwise expressly specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0053] With the development of economy and technology, consumers have higher and higher requirements for air quality, and the use of air treatment devices such as air humidifiers, air purification devices, air cooling and / or heating devices has become more and more widespread.

[0054] In the related art, water is often used to treat air in order to adjust the humidity, purity, and temperature of the air. Existing devices for treating air using water mainly consist of a water container containing water, a water treatment component disposed within the water container to lift or atomize the water, an air duct housing connected to the water container, and a fan that draws air into the air duct housing. When the air treatment device is in operation, water is first added to the water container, and then the fan and the water treatment component are started. The fan draws indoor air into the air duct housing through the air inlet of the air duct housing, and then passes through the upstream section of the air duct housing and is sent into the water container. The water lifted or atomized by the water treatment component is then humidified, purified, and / or cooled, and finally blown out of the air outlet of the air duct housing through the downstream section of the air duct housing, thereby improving the quality of the indoor air.

[0055] However, after a period of operation, the water in the water container of this device that uses water to treat air will gradually decrease. At this time, the water container needs to be removed in order to add water. However, the operation of removing the water container is often cumbersome, especially when this device is used as a module of a large air treatment equipment (such as an air conditioner or a fresh air treatment system), the water adding operation will be even more inconvenient.

[0056] The following describes a preferred technical solution of a device for treating air using water and an air conditioner indoor unit having the same according to an embodiment of the present invention.

[0057] First refer to Figure 1 and Figure 2 , Figure 1 1 is a schematic structural diagram of a device for treating air using water according to an embodiment of the present invention; Figure 2 FIG. 1 is an exploded schematic diagram of a device for treating air using water according to an embodiment of the present invention. Figure 1 and Figure 2 As shown, this embodiment provides a device 10 for treating air using water. From bottom to top, it comprises a fan housing 4, a water tank base 2, a water container 1, and an air outlet housing 3. A fan 5 is installed within the fan housing 4 and is securely connected to the water tank base 2. The water container 1 is accommodated on the water tank base 2, and an air outlet is provided at the top of the water container 1. The air outlet housing 3 covers the air outlet of the water container 1 and is connected to the top of the water container 1. A water treatment component 6 is installed within the water container 1. An air inlet duct is formed on the water tank base 2, and an air outlet duct 31 is formed on the air outlet housing 3. The water container 1 is connected to the air duct housing composed of the water tank base 2 and the air outlet housing 3, dividing the air duct housing into two parts: the water tank base 2 and the air outlet housing 3. The air duct housing is further divided into an air inlet duct located upstream of the water container 1 and an air outlet duct 31 located downstream of the water container 1.

[0058] Among them, the water container 1 is used to hold water; the water treatment component 6 arranged in the water container 1 is used to purify, humidify or cool the air in the water container 1; the fan 5 located inside the fan housing 4 is used to send the air in the environment into the water container 1 through the air inlet duct for treatment, and send the air after water treatment out from the air outlet duct 31.

[0059] Based on the above, the water tank base 2, the interior space of the water container 1, and the air outlet housing 3 together form a flow path for purifying air. When the device is in operation, the fan 5 is activated, drawing air from the external environment (e.g., indoor air) into the water tank base 2, i.e., the air inlet duct. The air then passes through the interior space of the water container 1, where it is purified, humidified, and / or cooled by the water mist or water curtain formed by the water treatment element 6. The air then enters the air outlet housing 3, i.e., the air outlet duct 31, from the air outlet at the top of the water container 1. The air is then discharged into the external environment (e.g., back into the room) through one or more air outlets of the air outlet housing 3.

[0060] Continue to refer to Figure 1 and Figure 2The device 10 for treating air using water further includes a water supply channel 32 and a cover. The water supply channel 32 is connected to and located above the air outlet channel 31 and is used to add water to the water container 1. The cover is disposed on the water supply channel 32 and is used to close the water supply channel 32. Thus, the water supply channel 32, the air outlet channel 31 located on the air outlet housing 3, and the interior space of the water container 1 constitute a water supply channel for adding water to the water container 1.

[0061] During use, when the device 10 for treating air with water needs to refill water into the water container 1 after working for a period of time, the staff can directly add water to the water adding channel 32. The water flows through the water adding channel 32 to the air outlet duct 31, and then falls into the interior of the water container 1 from the top of the water container 1, thereby adding water. Therefore, there is no need to remove the water container 1 from the device to add water, eliminating the process of disassembling the water container 1, and the water adding operation is convenient. In particular, when the device is used as a module of a large air treatment device (such as an air conditioner or a fresh air treatment system), a lot of disassembly work is eliminated, the water adding operation is convenient, and the water adding efficiency is high.

[0062] Specifically, the water adding channel 32 is formed on the air outlet shell 3 and is connected to the air outlet duct 31 on the air outlet shell 3. The air outlet duct 31 and the water adding channel 32 can be integrally formed by casting or injection molding, which is convenient for processing and facilitates the molding of the air outlet duct 31 and the water adding channel 32. The water adding channel 32 is located above the water container 1, which is more convenient for adding water than the water adding channel 32 formed at the bottom of the water container 1.

[0063] The connection between the water supply channel 32 and the air outlet channel 31 should be understood in a broad sense, that is, the outlet of the water supply channel 32 (i.e. Figure 1 The lower opening in the air duct 31 may be connected to the air inlet of the air outlet duct 31, or may be connected to the air outlet of the air outlet duct 31, or may be connected to the passage between the air inlet and the air outlet of the air outlet duct 31. For example, when the air outlet duct 31 is arranged in a vertical direction, the water supply channel 32 may also be arranged in a vertical direction so that the water outlet of the water supply channel 32 is connected to the air inlet of the air outlet duct 31.

[0064] Preferably, the water inlet of the water flow channel 32 (ie Figure 1 The upper opening in the air outlet) is arranged near the air outlet of the air outlet duct 31. Therefore, when the device 10 for treating air using water is used in a large air treatment device (such as an air conditioner), since the air outlet of the air outlet duct 31 is usually arranged on the side wall of the air conditioner casing to facilitate the discharge of water-treated air into the external environment (for example, backflow into the room) to improve air quality, the water injection port arranged near the air outlet can also be close to the side wall of the air conditioner casing, thereby facilitating the injection of water into the water injection port of the water injection channel 32 from the outside of the air conditioner casing, and the water injection operation is convenient.

[0065] Optionally, the water adding channel 32 may include a first section and a third section arranged in the vertical direction, and a second section arranged horizontally between the first section and the third section. The first section, the second section and the third section are connected in sequence. The inlet of the third section may be arranged close to the air outlet of the air outlet duct 31, and the outlet of the first section is connected to the air outlet duct 31.

[0066] Or, as Figure 1 As shown, the water adding channel 32 is arranged as a whole at an angle, thereby extending downward from the water inlet of the water adding channel 32 to the water outlet of the water adding channel 32. Compared with the previous optional method, there is a height difference between any two points on the water adding channel 32. Under the action of its gravity, water can be easily introduced into the water container 1 through the water adding channel 32, with a fast flow rate, and can avoid overflow caused by water flowing in the horizontal direction. It should be pointed out that the overall tilt setting of the water adding channel 32 does not mean that the slope of the entire water adding channel 32 is exactly the same. It can also be composed of multiple sections with different slopes connected in sequence. It only needs to have an overall downward tilt trend. Moreover, this embodiment does not limit each section of the water adding channel 32 to be a straight line segment. It can also be an arc segment.

[0067] Reference Figure 3 , Figure 3 This is a schematic diagram of the structure of the air outlet housing in a device for treating air using water according to an embodiment of the present invention. Figure 3 As shown, a portion of the water supply channel 32 extends into the air outlet duct 31, thereby preventing water from flowing along the upper wall of the air outlet duct 31 and improving the water supply effect. The portion of the water supply channel 32 extending into the air outlet duct 31 can be a circular tubular structure 322, which is easy to process and form.

[0068] like Figure 2 As shown, a sponge net 7 is further provided at the air outlet at the top of the water container 1. The sponge net 7 is located below the air outlet housing 3 and is connected to the top of the water container 1. The air treated by water passes through the sponge net 7 and flows into the air outlet duct 31 formed on the air outlet housing 3, thereby improving the air quality in the environment. The sponge net 7 can be bonded to the water container 1 or snap-fitted to the water container 1. For example, an annular groove is provided at the top of the water container 1, and the sponge net 7 is snapped into the annular groove to prevent the wind force generated by the water-treated air from blowing the sponge net 7 and causing the sponge net 7 to malfunction.

[0069] By setting the sponge net 7, after the air flows into the water container 1 for purification, humidification or cooling, some water molecules dissolve in the air to form water droplets, and the water droplets flow out of the air outlet at the top of the water container 1 with the air. When passing through the sponge net 7, some water droplets are blocked by the sponge net 7 and cannot enter the air outlet duct 31, so as to avoid excessive water droplets being discharged from the air outlet duct 31, resulting in excessive indoor air humidity and causing discomfort to the user.

[0070] The sponge net 7 is located below the air outlet housing 3. That is, the water adding channel 32 formed on the air outlet housing 3 is also located above the sponge net 7. When water is added to the water container 1 through the water inlet of the water adding channel 32, the water flowing out of the water adding channel 32 first passes through the sponge net 7 and then falls into the interior of the water container 1. In order to prevent the sponge net 7 from absorbing the water flowing into the water container 1, resulting in a reduction in the amount of water added, in this embodiment, the sponge net 7 can also be provided with a connecting hole. The connecting hole is directly opposite the water outlet of the water adding channel 32, so that the water flowing out of the water adding channel 32 directly falls into the interior of the water container 1 through the connecting hole, avoiding being absorbed by the sponge net 7.

[0071] Furthermore, a portion of the water adding channel 32 extending into the air outlet duct 31 can also pass through the sponge net 7, so that the water flowing out of the water adding channel 32 falls directly into the water container 1, avoiding the water flowing out of the water adding channel 32 from splashing onto the sponge net 7 during the process of falling into the connecting hole, thereby reducing the risk of water being absorbed by the sponge net 7 and causing the water volume to decrease, and further reducing the risk of water being contaminated by impurities adsorbed on the sponge net 7.

[0072] In addition, multiple air outlet ducts 31 can be formed on the air outlet housing 3, and the multiple air outlet ducts 31 can be evenly distributed in different directions. This can increase the air volume of the processed air of the device, thereby improving the efficiency of improving the air quality. The processed air can be blown into the environment from all directions, avoiding that only local air in the environment is improved. Furthermore, there can be multiple water supply channels 32, and a water supply channel 32 can be formed above each air outlet duct 31. By providing multiple water supply channels 32, when adding water, the staff can add water to the water inlets of multiple water supply channels 32 at the same time, thereby improving the water supply efficiency.

[0073] Based on the above, it should be pointed out that in order to prevent the water flowing into the air outlet duct 31 from the water adding channel 32 from being blown out by the air after water treatment, resulting in the inability to effectively add water to the water container 1, the staff can first turn off the fan 5 or reduce the speed of the fan 5 when adding water, so that the air outlet duct 31 does not export or exports a small amount of air, thereby reducing the impact on the water flowing into the water container 1 from the air outlet duct 31.

[0074] The cover is disposed at the water inlet of the water supply channel 32. It closes the water supply channel 32 during operation or when water is not required. This prevents impurities from entering the water container 1 through the water inlet, thereby contaminating the water in the water container 1. It also prevents treated air from flowing out of the water inlet of the water supply channel 32, thereby preventing it from affecting the air flow. This, of course, is related to fluid design and can be determined through simulation or other methods. For example, the cover can be a plate-like structure that horizontally covers the water inlet of the water supply channel 32 to block the water inlet.

[0075] The cover can be detachably mounted on the water inlet of the water supply channel 32. Thus, by removing the cover, the water supply channel 32 can be opened when water needs to be added to the water container 1, thereby facilitating water addition. For example, the plate-shaped cover can be connected to the air outlet housing 3 via a screw structure or a snap-fit ​​structure. Both screw and snap-fit ​​connection techniques are well known to those skilled in the art and will not be described in detail here.

[0076] Alternatively, the cover can be rotatably mounted at the water inlet of the water supply channel 32. This arrangement, compared to a detachable connection, prevents the cover from being detached from the device, thereby preventing the cover from being lost after removal and thus preventing the water supply channel 32 from being closed. The water supply channel 32 can be opened and closed simply by rotating the cover, making it easy to open and close. For example, the plate-shaped cover can be hinged to the side wall at the water inlet of the water supply channel 32 via a hinge axis. During use, the plate-shaped cover can be pulled to rotate about the hinge axis to open or close the water inlet.

[0077] In summary, the device 10 for treating air using water provided in an embodiment of the present invention can directly replenish water to the water container 1 by adding water to the water adding channel 32, without removing the water container 1 from the device, thus eliminating the process of disassembling the water container 1 and making the water adding operation convenient.

[0078] Reference Figure 4 , Figure 4 This is a schematic diagram of the connection between the water tank base and the fan housing in an embodiment of the present invention in which water is used to treat air. Figure 2 and Figure 4 As shown, in the above embodiment, the water tank base 2 may include a base shell 21 and a mounting shell 22. The interior of the base shell 21 is hollow, and the mounting shell 22 is arranged inside the base shell 21. One end of the mounting shell 22 is connected to the side wall of the base shell 21, and a mounting opening is provided on the side wall of the base shell 21, so that the water container 1 can be installed on the mounting shell 22 through the mounting opening.

[0079] To enable the fan 5 located below the water tank base 2 to draw ambient air into the air inlet duct of the water tank base 2, a gap is defined between the sidewalls of the mounting housing 22 and the sidewalls of the base housing 21. When the device is operating, the fan 5 draws ambient air into the fan housing 4, where it then flows through this gap into the air inlet duct of the water tank base 2 and into the interior of the water container 1. Furthermore, multiple support brackets 23 are spaced apart within the gap between the sidewalls of the mounting housing 22 and the sidewalls of the base housing 21. These support brackets 23 support the mounting housing 22, preventing deformation of the water tank base 2 and enabling the mounting housing 22 to stably bear the weight of the water container 1.

[0080] The water container 1 can be a regular shape such as a box or cylinder, or any other irregular shape, as long as the water container 1 has a cavity for holding water. The air inlet of the water container 1 is disposed on the side wall of the water container 1 and is connected to the air outlet at the top, so that air from the air inlet duct upstream of the water container 1 flows into the water container 1 through the air inlet and, after being treated by water, flows into the air outlet duct 31 through the air outlet.

[0081] The water treatment component 6 is accommodated inside the water container 1, and purifies, humidifies or cools the air entering the water container 1. Among them, the water treatment component 6 can only purify, humidify or cool the air, or it can purify, humidify and cool the air at the same time. For example, the water treatment component 6 includes a power supply and an ultrasonic atomizer, the power supply is electrically connected to the ultrasonic atomizer, and the ultrasonic atomizer is arranged in the water container 1, which is used to make the water in the water container 1 produce water vapor. When in use, air flows into the water container 1 from the air inlet on the side wall of the water container 1, part of the air merges with the water vapor generated by the ultrasonic atomizer, and the air carrying a certain amount of water vapor flows to the air outlet duct 31, and impurities such as dust, hair or lint in the air dissolve in the water to form water droplets, and some water droplets are blocked by the sponge net 7 and cannot pass through the sponge net 7, thereby filtering out impurities, thereby achieving purification. Of course, if only the air needs to be humidified, the sponge net 7 can be omitted, so that the air entering the water container 1 can be blown out from the air outlet of the air outlet shell 3 with the atomized water droplets.

[0082] like Figure 2 As shown, in some embodiments of the present invention, the water treatment component 6 can be a centrifugal water-spraying component, a water spray hole is provided at the top of the centrifugal water-spraying component, and there is a gap between the bottom end of the centrifugal water-spraying component and the bottom of the water container 1; the centrifugal water-spraying component can rotate to lift the water in the water container 1 from the above-mentioned gap, and spray it out from the water spray hole at the top of the centrifugal water-spraying component to form a water curtain for purifying the air entering the water container 1.

[0083] By configuring the water treatment component 6 as a centrifugal water-spinning component, when in use, the centrifugal water-spinning component rotates 360 degrees within the water container 1, causing the water within the water container 1 to be drawn into the centrifugal water-spinning component through the gap between the bottom end of the centrifugal water-spinning component and the bottom of the water container 1, and then ejected from the water spray hole at the top of the centrifugal water-spinning component, forming a planar water curtain within the water container 1. When air passes through the water curtain, it dissolves with the water molecules in the water curtain, increasing the humidity and lowering the temperature of the air. At the same time, impurities such as dust, hair, or lint in the air dissolve with the water in the water curtain to form water droplets. When the air passes through the sponge net 7, the water droplets are blocked by the sponge net 7 and cannot pass through the sponge net 7, thereby filtering out the impurities. The filtered air flows out from the air outlet duct 31, thereby achieving humidification, purification, and cooling functions.

[0084] In addition, since the centrifugal water-spinning element forms a planar water curtain inside the water container 1, the air entering the water container 1 from the air inlet on the side wall must pass through the water curtain before flowing into the air outlet duct 31, thereby increasing the amount of air dissolved with water molecules and improving the humidification, purification and cooling effects.

[0085] The fan housing 4 can be a box structure or a cylindrical structure. The bottom and top of the fan housing 4 are both provided with openings, and the interior has a cavity for accommodating the fan 5. The opening at the bottom of the fan housing 4, the cavity and the opening at the top are connected to form a flow channel for supplying air to the air duct housing, and the flow channel is connected to the external environment or the air duct in the large air treatment equipment, so that when the fan 5 is started, the air in the external environment or the air in the air duct in the large air treatment equipment is sent into the air inlet duct of the air duct housing. It is worth noting that when the large air treatment equipment is an air conditioner, the air duct on the air conditioner that is connected to the fan housing 4 is isolated from the heat exchange duct on the air conditioner (see description below) to prevent the air heated by the heat exchange duct from flowing into the air duct housing, resulting in water treatment for cooling, thereby reducing heat exchange losses.

[0086] The fan housing 4 and the water tank base 2 can be connected by welding, by screwing, or by integrally forming by injection molding. Thus, the fan housing 4 and the water tank base 2 become a whole, which improves the stability of the device and eliminates the process of assembling the fan housing 4 and the water tank base 2.

[0087] The fan 5 includes a motor 51 and blades 52. The motor shaft of the motor 51 is in transmission connection with the blades 52. The motor shaft drives the blades 52 to rotate so that air in the environment flows from the opening at the bottom of the fan housing 4 into the interior of the fan housing 4. The motor 51 can be connected to the side wall of the fan housing 4, or a mesh support frame with mesh holes is provided inside the fan housing 4. The motor 51 is mounted on the mesh support frame, and the motor shaft of the motor 51 extends through the mesh holes of the mesh support frame and is in transmission connection with the blades 52.

[0088] like Figure 2 As shown, in a preferred embodiment of the present invention, motor 51 is a dual-shaft motor, a first motor shaft of which is drivingly connected to fan blades 52, and a second motor shaft of which penetrates the bottom of water container 1 and is drivingly connected to the centrifugal water-spinning element. Thus, motor 51 can simultaneously drive fan blades 52 and the centrifugal water-spinning element to rotate. Compared with providing two single-shaft motors 51 to drive fan blades 52 and the centrifugal water-spinning element separately, the structure is simpler and energy is saved.

[0089] In addition, a plug-in port is provided on the side wall of the fan housing 4. The device also includes a fan grille 41, which is removably inserted into the plug-in port and located below the fan 5. Thus, the fan grille 41 protects the fan 5, preventing other structures from accidentally contacting the fan 5 and causing it to malfunction. Furthermore, when handling the device, the fan grille 41 prevents workers from directly touching the fan blades 52 and causing scratches.

[0090] An embodiment of the present invention further provides an air conditioner indoor unit, particularly a cabinet-type air conditioner indoor unit, comprising a housing and a device 10 for treating air using water. A heat exchange duct isolated from the device is further provided within the housing. The heat exchange duct is independent of the flow channel on the device for purifying, humidifying, or cooling the air, thereby preventing air from flowing into the flow channel after being heated by the heat exchange duct, causing the air to be cooled by the water in the water container 1, thereby reducing heat exchange losses. Specifically, the housing of the air conditioner indoor unit is further provided with an air inlet and an air outlet. The air inlet, the interior of the housing, and the air outlet are interconnected to form the heat exchange duct. A heat exchanger connected to the heat exchange duct is provided within the housing, the heat exchanger being located between the air inlet and the air outlet. This allows air entering the interior of the housing to first flow through the heat exchanger for heat exchange before being discharged into the room through the air outlet to regulate the indoor temperature and achieve cooling or heating.

[0091] In one practical implementation, the device 10 for treating air using water can be installed within a housing and removably connected to the housing. The air outlet of the air duct 31 on the device is connected to the external environment. When the water container 1 is depleted after the air conditioner has operated for a period of time, the device can be removed from the air conditioner, and the cover can be opened to add water to the water supply channel 32. Compared to the related art method that requires removing the water container 1, this method eliminates the need for disassembly, simplifies the disassembly process, and facilitates water addition.

[0092] Reference Figure 5 , Figure 5 This is a front view of another device for treating air using water according to an embodiment of the present invention. Figure 5As shown, in another feasible manner, a water inlet and an air supply port may be provided on the side wall of the shell, and the device 10 for treating air with water also includes a bracket 8, and the air outlet of the air outlet duct 31 and the water inlet of the water supply channel 32 are both provided on the bracket 8, and the water inlet on the bracket 8 is opposite to the water inlet on the shell, and the air outlet on the bracket 8 is opposite to the air supply port on the shell.

[0093] When the air conditioner indoor unit has been operating for a period of time and the water in water container 1 is depleted, the operator can add water directly from the water inlet on the housing to the water inlet on the bracket 8. The water flows through the water inlet and the water inlet in sequence into the water addition channel 32, and then flows into the interior of the water container 1 along the air outlet duct 31 connected to the water addition channel 32, thus completing the water addition. This allows water to be added to the water container 1 without having to disassemble the water container 1 or the device from the indoor unit, eliminating the need to disassemble the water container 1 and the device. This makes water addition convenient and efficient.

[0094] Figure 6 This is a structural schematic diagram of another device for treating air using water according to an embodiment of the present invention, in which the cover is in a closed state; Figure 7 yes Figure 6 A partial enlarged view of point A in the middle; Figure 8 This is a structural schematic diagram of another device for treating air using water according to an embodiment of the present invention, in which the cover is in an open state; Figure 9 yes Figure 8 Here, the cover 9 for closing the water inlet can be set on the bracket 8, and the cover 9 can be detachably or rotatably connected to the bracket 8. Figures 6 to 9 In the example shown, the cover body 9 may include a front panel, two side panels connected to the front panel and arranged opposite to each other, and an upwardly inclined bottom panel. The front panel, the side panels, and the bottom panel define a water filling trough for filling water, and the bottom panel is provided with a conduit 91 that can be inserted into the water supply channel 32. With this arrangement, the water filling trough can accommodate a certain amount of water, and the water filling trough can act as a buffer when adding water. The upwardly inclined bottom panel facilitates the introduction of water in the water filling trough into the conduit 91. Moreover, because the conduit 91 is inserted into the water supply channel 32, it can further ensure that all water discharged from the water filling trough can be discharged into the water supply channel 32, avoiding loss during the process of water flowing from the water filling trough to the water supply channel 32.

[0095] Specifically, two connecting plates are provided on the inner wall of the bracket 8, and the cover 9 is located between the two connecting plates. The two side plates extend downward to form cantilevers. Each cantilever is hinged to a nearby connecting plate through a hinge shaft, thereby allowing the cover 9 to rotate around the hinge shaft. The axis of the hinge shaft is parallel to the horizontal plane, and the front panel is used to block the water inlet. Here, it is worth noting that Figure 8 and Figure 9As shown, the cover 9 can rotate within a range of 0 to 90 degrees. When the cover 9 is rotated to its maximum angle, the conduit 91 on the bottom plate remains inserted into the water supply channel 32. At this point, the conduit 91 is tilted. An upwardly extending water baffle 321 is also provided at the water inlet of the water supply channel 32. The water baffle 321 is positioned toward the bracket 8. When the cover 9 is rotated to open the water inlet, the water baffle 321 prevents water from flowing out of the tilted conduit 91 from splashing outside the water inlet.

[0096] Furthermore, the top of the cover 9 is provided with an elastic buckle for engaging with the bracket 8, and the bottom of the cover 9 is rotatably connected to the bracket 8. Thus, by operating the elastic buckle, the cover 9 can be flexibly opened and closed, making it convenient to open the water inlet on the bracket 8 when adding water and close the water inlet after adding water. Figure 8 and Figure 9 As shown in the figure, the top of the front panel of the cover body 9 is provided with a plate-shaped locking tongue 92, and the bracket 8 is provided with a push-on elastic lock buckle 81. The plate-shaped locking tongue 92 cooperates with the push-on elastic lock buckle 81 to engage or release. When adding water, the front panel is pressed to release the plate-shaped locking tongue 92 from the push-on elastic lock buckle 81, and the front panel is rotated to open the water inlet. When the water is added, the front panel is rotated to close the water inlet, and then the front panel is pressed again to engage the plate-shaped locking tongue 92 with the push-on elastic lock buckle 81. The technical solution of the plate-shaped locking tongue 92 and the push-on elastic lock buckle 81 is well known to those skilled in the art and will not be described in detail here.

[0097] The water adding process of the device 10 for treating air with water provided in this embodiment is as follows: when adding water, the front panel of the cover body 9 is pressed to loosen the plate-shaped lock tongue 92 and the pressing elastic lock buckle 81, and the top of the front panel on the cover body 9 is separated from the bracket 8, and the front panel is pulled to rotate so that the cover body 9 is flipped outward, and then water is poured into the water filling tank. The water flows into the water adding channel 32 through the conduit 91, flows into the air outlet duct 31 from the circular tubular structure 322 through the water adding channel 32, and then flows out through the air inlet of the air outlet duct 31, passes through the sponge net 7, and falls into the water container 1.

[0098] In summary, an embodiment of the present invention provides a device 10 for treating air using water and an air conditioner indoor unit having the same. The device 10 for treating air using water includes a water container 1, a water treatment component 6, an air duct housing, a fan 5, a water supply channel 32, and a cover 9. The water container 1 is used to hold water. The water treatment component 6 is disposed within the water container 1 and is used to purify, humidify, or cool the air entering the water container 1. The air duct housing is in communication with the water container 1 and has an air inlet duct located upstream of the water container 1 and an air outlet duct 31 located downstream of the water container 1. The fan 5 is used to deliver ambient air into the water container 1 through the air inlet duct for treatment and to deliver the water-treated air from the air outlet duct 31. The water supply channel 32 is in communication with the air outlet duct 31 and is located above the air outlet duct 31. The cover 9 is disposed on the water supply channel 32 and is used to close the water supply channel 32. With the above arrangement, when the device 10 for treating air with water has been operating for a period of time and the water container 1 needs to be refilled with water, the operator simply opens the cover 9 and adds water to the water adding channel. The water flows through the water adding channel into the air outlet duct 31 and then flows along the air outlet duct 31 into the interior of the water container 1, thereby completing the water addition. Therefore, there is no need to disassemble the water container 1 for water addition, thus eliminating the need for disassembly of the water container 1 and facilitating the water addition operation.

However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art may make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will fall within the scope of protection of the present invention.
