Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to an air conditioning indoor unit and an air conditioner. Background Art

[0002] When cooling, the evaporator of the air conditioner indoor unit will produce condensed water. In some cases, such as inspection and repair, the base needs to be removed and the condensed water will drip directly, which can easily cause pollution. Summary of the invention

[0003] The problem solved by the invention is how to avoid the pollution caused by condensed water dripping when the base of the indoor unit of the air conditioner is removed.

[0004] To solve the above problems, the present invention provides an air-conditioning indoor unit on one hand, which includes a base structure and a first water tank, a second water tank is arranged on the base structure, the first water tank is located below the second water tank, and the positions of the first water tank and the second water tank correspond to the position of the evaporator of the air-conditioning indoor unit.

[0005] Therefore, the first water tank and the second water tank are set, and the second water tank is used to receive the condensation water dripping during normal operation, and the first water tank is used to receive the condensation water dripping after the base structure is removed, thereby preventing the condensation water from directly dripping after the base structure is removed and causing pollution to the air-conditioning indoor unit and the indoor environment.

[0006] Optionally, the base structure includes an upper base and a lower base, the upper base is detachably connected to the lower base, and the second water tank is arranged on the lower base.

[0007] Therefore, the base structure of the air-conditioning indoor unit is configured as the upper base and the lower base which are detachably connected, and the second water tank is arranged on the lower base. When it is necessary to perform operations on the interior of the air-conditioning indoor unit, such as inspection and repair, the lower base is removed to make room for operation, and condensed water is collected by the first water tank at the same time, which makes operation convenient and highly practical.

[0008] Optionally, a tube protection plate is further included, wherein the tube protection plate includes a tube protection plate body, and the first water tank is connected to the tube protection plate body.

[0009] Therefore, by setting the first water tank to be connected to the pipe protection plate body of the pipe protection plate, the first water tank can be reliably installed inside the air-conditioning indoor unit. The pipe protection plate can not only protect the pipeline bundle but also have the function of receiving condensed water, and has high reliability and strong practicality.

[0010] Optionally, the first water tank is integrally connected to the pipe protection plate body.

[0011] Therefore, the first water tank is integrally connected to the tube protection plate body, the tube protection plate is integrally formed, and there is no need to provide an additional mounting structure to mount the first water tank on the tube protection plate body, which has high reliability and strong practicality.

[0012] Optionally, the pipe protection plate further includes a water retaining structure, wherein the water retaining structure is located at an edge of the first water tank and is connected to a side wall of the first water tank.

[0013] Therefore, by setting the water retaining structure, on the one hand, the dripping condensation water is blocked by the water retaining structure to prevent the dripping condensation water from splashing in the first water tank and causing pollution to the internal structure of the air-conditioning indoor unit; on the other hand, the depth of the first water tank can be deepened to a certain extent, thereby enhancing the ability of the first water tank to receive condensation water.

[0014] Optionally, the water retaining structure includes a rib structure and / or a step-shaped structure.

[0015] Therefore, the water retaining structure is configured to include a rib structure and / or a step-shaped structure, which has a simple structure, is easy to process, and can easily achieve a water retaining effect. In addition, the step-shaped structure also has a larger condensate receiving range and high reliability.

[0016] Optionally, the water retaining structure includes at least one guide portion, and the guide portion is inclined toward one side of the first water trough.

[0017] Therefore, the water retaining structure has at least one guide portion, and the guide portion is inclined toward one side of the first water trough. The guide portion prevents condensed water from splashing out of the first water trough. The guide portion can also increase the range of the first water trough for receiving condensed water to a certain extent, and guide the condensed water, making it easier for the condensed water to slide into the first water trough.

[0018] Optionally, a groove is provided on the water retaining structure, and the groove is located on a side of the water retaining structure away from the first water tank.

[0019] Therefore, a groove is provided on the water retaining structure, and the groove is located on the side of the water retaining structure away from the first water tank. It can not only enhance the rigidity and stability of the pipe guard plate, but also perform glue reduction treatment by setting the groove to avoid shrinkage due to excessive thickness difference, which affects the rigidity and stability of the pipe guard plate. It has high reliability and strong practicality.

[0020] Optionally, the first water tank is at least partially in contact with the lower bottom surface of the lower base.

[0021] Therefore, by at least partially fitting the first water trough against the lower bottom surface of the lower base, the connection between the first water trough and the lower base is strengthened, so that when disassembling and assembling the lower base, the first water trough can play a role of positioning support to a certain extent, and the possibility of condensation water flowing out from the gap between the first water trough and the lower base is reduced to a certain extent, which has high reliability and strong practicality.

[0022] Optionally, a support plate is further included, wherein the support plate is connected to the side wall of the first water tank, and the support plate is at least partially in contact with the lower bottom surface of the lower base.

[0023] Therefore, the pipe protection plate also includes a support plate, which is connected to the side wall of the first water tank, and the support plate is at least partially in contact with the lower bottom surface of the lower base, thereby avoiding the side wall of the first water tank from directly contacting the lower bottom surface of the lower base. While playing a positioning and supporting role for the lower base, the elastic space for installing the first water tank and the lower base is enhanced, and the difficulty of installing the lower base and the first water tank is reduced.

[0024] Optionally, it further includes a first drain pipe, which is connected to the first water tank.

[0025] Therefore, by providing the first drain pipe, the condensed water received in the first water tank can be discharged in time to avoid the accumulation of condensed water in the first water tank, which is highly practical.

[0026] Optionally, the first drain pipe is connected to one end of the first water tank, and the end of the first water tank connected to the first drain pipe is inclined downward.

[0027] Therefore, by setting the first water tank to be inclined, the condensed water in the first water tank can flow out from the first drain pipe more conveniently, thereby avoiding the residue of condensed water.

[0028] Optionally, a second drain pipe is further included, and the first water tank and the second water tank are respectively connected to the second drain pipe.

[0029] Therefore, when the lower base is installed on the upper base, condensed water drops into the second water tank and is discharged through the second drain pipe. When the lower base is removed from the upper base, condensed water drops into the first water tank and is discharged through the second drain pipe, thereby avoiding the accumulation of condensed water inside the air-conditioning indoor unit to cause pollution. The first water tank does not need to be connected to the external environment with a separate drain pipe, and has a simple structure and strong practicality.

[0030] Optionally, a sponge is further included, and the sponge is located on the back side of the first water tank side wall.

[0031] Therefore, by arranging a sponge on the back side of the first water tank side wall, it has an isolating and heat-insulating effect to a certain extent, and avoids condensation of water droplets on the back side of the first water tank side wall, which is highly practical.

[0032] Optionally, the cross-sectional shape of the first water tank is V-shaped, concave arc-shaped or concave step-shaped.

[0033] Therefore, the cross-sectional shape of the first water trough is V-shaped, concave arc-shaped or concave step-shaped. The first water trough has a large range for receiving condensed water and a small width of the bottom of the first water trough, which is conducive to the gathering of condensed water and convenient for subsequent discharge.

[0034] Another aspect of the present invention provides an air conditioner, comprising any one of the air conditioner indoor units described above. The beneficial effects of the air conditioner are the same as those of the air conditioner indoor unit, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] In addition, all directions or positional relationships mentioned in the embodiments of this specification are based on the positional relationships in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not imply or suggest that the referred device or element must have a specific orientation, and should not be understood as a limitation on the present invention.

[0053] An embodiment of the present invention provides an air-conditioning indoor unit, including a base structure 1 and a first water tank 210, wherein a second water tank 121 is arranged on the base structure 1, and the first water tank 210 is located below the second water tank 121, and the positions of the first water tank 210 and the second water tank 121 correspond to the position of the evaporator 3 of the air-conditioning indoor unit.

[0054] like Figure 1 and Fig.11 As shown, it should be noted that the evaporator 3 is located inside the air-conditioning indoor unit, the first water tank 210 and the second water tank 121 are both located below the evaporator 3 inside the air-conditioning, the first water tank 210 is used to receive condensed water after the base structure 1 is removed, and the air-conditioning indoor unit can be a wall-mounted air-conditioning indoor unit.

[0055] It should be noted that, without conflicting with the contents of the present invention, the air-conditioning indoor unit may include some other components, such as a wall-mounted panel. There are many ways to set the first water tank 210. For example, the first water tank 210 can be set on the outer casing of the air conditioner; of course, the first water tank 210 can also be set on the wall-mounted panel, which is not a limitation.

[0056] It should be noted that the second water tank 121 is provided to ensure that the air conditioner indoor unit can receive condensed water when in normal use. In some embodiments, the base structure 1 only includes the lower base 12. It should be noted that the first water tank 210 should not hinder the installation and removal of the lower base 12. When the lower base 12 is removed, the first water tank 210 receives the condensed water dripping from the evaporator 3, preventing the condensed water from dripping directly and causing pollution, thereby improving the user experience.

[0057] The advantage of such an arrangement is that the first water tank 210 and the second water tank 121 are arranged, and the second water tank 121 receives condensed water dripping during normal operation, and the first water tank 210 receives condensed water dripping after the base structure 1 is removed, thereby preventing condensed water from directly dripping after the base structure 1 is removed, thereby preventing the air conditioner indoor unit and the indoor environment from being polluted by the condensed water.

[0058] like Figure 1 and Fig.11 As shown, the base structure 1 includes an upper base 11 and a lower base 12 , the upper base 11 is detachably connected to the lower base 12 , and the second water tank 121 is disposed on the lower base 12 .

[0059] like Figure 1 As shown, it should be noted that the lower base 12 is located below the upper base 11. According to the structure of the lower base 12, the position of the first water tank 210 may vary to a certain extent. For example, in order to facilitate the installation of the cross-flow fan, the lower bottom surface contour of the lower base 12 is arc-shaped, and the first water tank 210 is located below the arc-shaped bottom surface of the lower base 12. That is to say, at least part of the structure of the lower base 12 is located above the first water tank 210. It should be noted that there are many ways to detachably connect the upper base 11 and the lower base 12, such as snap-on, hanging, etc., which are not intended to be limiting and will not be described in detail here. However, the provision of the first water tank 210 should not restrict the removal of the lower base 12.

[0060] The advantage of such a configuration is that the base structure 1 of the air-conditioning indoor unit is configured as the upper base 11 and the lower base 12 which are detachably connected, and the second water tank 121 is disposed on the lower base 12. When it is necessary to perform operations on the interior of the air-conditioning indoor unit, such as inspection and repair, the lower base 12 is removed to make room for operation, and at the same time, condensed water is collected through the first water tank 210, which facilitates operation and is highly practical.

[0061] like Figure 1As shown, the air conditioner further comprises a pipe protection plate 2, and the first water tank 210 is connected to the pipe protection plate 2. The pipe protection plate 2 comprises a pipe protection plate body 230, and the first water tank 210 is connected to the pipe protection plate body 230. The pipe protection plate 2 is located at the rear side of the air conditioner indoor unit, and the upper end of the pipe protection plate 2 is mounted on the upper base 11, or the pipe protection plate 2 can also be mounted on the wall-mounted plate or other components of the air conditioner indoor unit.

[0062] In some embodiments, the first water tank 210 is integrally connected to the tube protection plate body 230. In this way, the first water tank 210 is integrally connected to the tube protection plate body 230, the tube protection plate 2 is integrally formed, and there is no need to set up a separate mounting structure to mount the first water tank 210 on the tube protection plate body 230, which has high reliability and strong practicality. It should be noted that in some other embodiments, the first water tank 210 and the tube protection plate body 230 can also be detachably connected, which will not be described in detail here.

[0063] It should be noted that if Figure 1 As shown in the figure, the first water tank 210 and the second water tank 121 are located at the rear side of the air conditioner as an example to illustrate the technical solution of the present invention. Here, the rear side of the air conditioner is attached Figure 1 In the opposite direction of the middle X-axis, it should be noted that, in some other embodiments, the lower base 12 may also include a third water tank, and the third water tank is located at the front end of the lower base 12. Here, the front end of the lower base 12 refers to the end of the lower base 12 located in the positive direction of the X-axis, and the third water tank is used to receive condensed water. A fourth water tank may also be arranged under the third water tank. At this time, the fourth water tank needs to be installed on other structures, which will not be described in detail here.

[0064] The advantage of such a configuration is that by configuring the first water tank 210 to be connected to the tube guard plate body 230 of the tube guard plate 2, the first water tank 210 can be reliably installed inside the air-conditioning indoor unit. The tube guard plate 2 can not only protect the pipeline bundle but also receive condensed water, and has high reliability and strong practicality.

[0065] It should be noted that, in order to better receive condensed water when the lower base 12 is removed, the first water tank 210 is located on the side of the tube guard plate body 230 close to the lower base 12. Considering that the contour of the lower bottom surface of the lower base 12 is generally arc-shaped, the lower end of the tube guard plate body 230 is inclined toward the side close to the lower base 12. In this way, the first water tank 210 is more reasonably positioned on the tube guard plate body 230, ensuring that condensed water can be received in a larger range after the lower base 12 is removed.

[0066] like Figure 1 , Figure 2 , Figure 8 , Fig. 9 and Fig.10 As shown, in some embodiments, a receiving portion 231 for receiving a bundle of pipes is provided on the pipe protection plate body 230, and the receiving portion 231 is located on a side of the pipe protection plate body 230 away from the lower base 12. In this way, the receiving portion 231 has a larger receiving space and is away from the first water tank 210, and the condensed water inside the first water tank 210 and the air conditioner indoor unit will not enter the receiving portion 231, and the reliability is high. The receiving portion 231 is at least partially located below the first water tank 210. In this way, on the basis of obtaining a larger receiving space, the positions of the receiving portion 231 and the first water tank 210 are staggered as much as possible to prevent the condensed water condensed on the back of the side wall of the first water tank 210 from affecting the bundle of pipes in the receiving portion 231.

[0067] like Figure 2 , Figure 3 and Figure 4 As shown, in the above embodiment, the pipe protection plate 2 further includes a water retaining structure 220 , and the water retaining structure 220 is located at the edge of the first water tank 210 , and the water retaining structure 220 is connected to the side wall of the first water tank 210 .

[0068] It should be noted that the first water trough 210 includes at least one side wall, wherein at least one of the side walls is correspondingly provided with the water retaining structure 220, the water retaining structure 220 is located at the edge of the side wall of the first water trough 210, and the water retaining structure 220 is integrally connected to the side wall of the first water trough 210 or detachably connected.

[0069] The advantage of such a configuration is that, by providing the water retaining structure 220, on the one hand, the dripping condensed water is blocked by the water retaining structure 220 to prevent the dripping condensed water from splashing in the first water tank 210 and polluting the internal structure of the air-conditioning indoor unit; on the other hand, the depth of the first water tank 210 can be deepened to a certain extent, thereby enhancing the ability of the first water tank 210 to receive condensed water.

[0070] The water retaining structure 220 includes a rib structure 221 and / or a step-shaped structure 222 .

[0071] like Figure 3 and Figure 4 As shown, in some embodiments, the water retaining structure 220 includes a rib structure 221, and the rib structure 221 is arranged on the side wall edge of the first water tank 210. It should be noted that the rib structure 221 is also connected to the pipe protection plate body 230. For example, as shown in the attached Figure 3 and Figure 4As shown, the rib structure 221 is disposed at the top of the side wall of the first water tank 210 along the Y-axis direction in the figure. It should be noted that all side walls of the first water tank 210 may be provided with the rib structure 221 .

[0072] like Figure 3 and Figure 4 As shown, in some embodiments, the first water tank 210 includes a first side wall 211, which is located on the side of the first water tank 210 away from the lower base 12, that is, the first water tank 210 is located on the side opposite to the X axis in the figure, and the top of the first side wall 211 is provided with the step-like structure 222. Figure 4 As shown, it should be noted that, in the above embodiment, the edge of the step-like structure 222 may also be provided with the rib structure 221, and the number of the rib structure 221 and the step-like structure 222 can be determined according to specific needs, and the setting method and structure thereof can be adaptively changed, which will not be described in detail here.

[0073] The advantage of such a configuration is that the water retaining structure 220 is configured to include a rib structure 221 and / or a step-shaped structure 222, which has a simple structure, is easy to process, and can easily achieve a water retaining effect. In addition, the step-shaped structure 222 also has a larger condensate receiving range and high reliability.

[0074] The water retaining structure 220 includes at least one guide portion 2221, and the guide portion 2221 is inclined toward one side of the first water tank 210. The guide portion 2221 is inclined downward at one end close to the first water tank 210, and the guide portion 2221 has a guide function, and the guide portion 2221 is a guide slope or a curved surface. Figure 3 and Figure 4 As shown, at least one guide portion 2221 is provided on the step-shaped structure 222. The number and the inclination angle of the guide portion 2221 can be determined according to specific circumstances, such as Figure 4 As shown, in some embodiments, two guide portions 2221 connected in sequence are provided on the step-like structure 222. It should be noted that in some embodiments, the guide portion 2221 can also be vertically arranged, that is, the guide direction of the guide portion 2221 is consistent with the vertical direction, and in this case, the guide portion 2221 is a vertical surface. It should be noted that the rib structure 221 can also include the guide portion 2221, which will not be described in detail here.

[0075] The advantage of such a configuration is that the water retaining structure 220 has at least one guide portion 2221, and the guide portion 2221 is inclined toward one side of the first water trough 210. The guide portion 2221 prevents condensed water from splashing out of the first water trough 210. The guide portion 2221 can also increase the range of the first water trough 210 to a certain extent to receive condensed water, and guide the condensed water to facilitate the condensed water to slide into the first water trough 210.

[0076] In the above embodiment, a groove 223 is provided on the water retaining structure 220 , and the groove 223 is located on a side of the water retaining structure 220 away from the first water tank 210 .

[0077] like Figure 4 As shown, in some embodiments, the groove 223 is located on the side of the step-like structure 222 away from the first water tank 210, that is, on the side of the step-like structure 222 opposite to the X-axis in the figure. It should be noted that in order to better receive condensed water and accommodate pipeline bundles, in order to enhance rigidity and stability, the pipe protection plate 2 may not be a thin plate structure, and the thickness of the water retaining structure 220 is thicker than other areas, but this is not conducive to the flow of liquid plastic in injection molding.

[0078] The advantage of such a setting is that a groove 223 is provided on the water retaining structure 220, and the groove 223 is located on the side of the water retaining structure 220 away from the first water tank 210, which can not only enhance the rigidity and stability of the pipe guard plate 2, but also reduce the glue by providing the groove 223 to avoid shrinkage due to excessive thickness difference, thereby avoiding affecting the rigidity and stability of the pipe guard plate 2, and having high reliability and strong practicality.

[0079] like Figure 2 , Figure 5 , Figure 6 and Figure 7 As shown, the first water tank 210 is at least partially in contact with the lower bottom surface of the lower base 12. In some embodiments, the first water tank 210 includes a second side wall 212, and the second side wall 212 is located on the side of the first water tank 210 close to the lower base 12. That is, the second side wall 212 is attached to the lower base 12. Figure 2 The first water tank 210 is located on the side wall in the positive direction of X, and the second side wall 212 is located below the lower base 12 . The second side wall 212 is at least partially in contact with the lower bottom surface of the lower base 12 .

[0080] The advantage of such a configuration is that, by at least partially fitting the first water trough 210 against the lower bottom surface of the lower base 12, the connection between the first water trough 210 and the lower base 12 is enhanced, so that when disassembling and assembling the lower base 12, the first water trough 210 can, to a certain extent, play a role in positioning and supporting, and, to a certain extent, reduces the possibility of condensed water flowing out of the gap between the first water trough 210 and the lower base 12, thereby achieving high reliability and strong practicality.

[0081] like Figure 5 As shown, the pipe protection plate 2 further includes a support plate 213 , which is connected to the side wall of the first water tank 210 , and the support plate 213 is at least partially in contact with the lower bottom surface of the lower base 12 .

[0082] In some embodiments, the lower end of the support plate 213 is connected to the second side wall 212, and the upper end of the support plate 213 is in contact with the lower bottom surface of the lower base 12. It should be noted that the position where the support plate 213 is in contact with the lower base 12 can be determined according to actual needs, and it should be able to position and support the lower base 12 to a certain extent, but it does not affect the removal of the lower base 12. For example, the support plate 213 is tilted relative to the second side wall 212. In some embodiments, an elastic pad is provided at the position where the support plate 213 is in contact with the lower base 12 to enhance its elasticity and sealing performance.

[0083] like Figure 6 and Figure 7 As shown, in the above embodiment, a slot 122 is provided on the lower base 12 , and an inserting portion 214 is provided on the support plate 213 . Along the removal direction of the lower base 12 , the slot 122 is plugged and matched with the inserting portion 214 .

[0084] It should be noted that the plug-in portion 214 may also be a plug-in strip disposed on the support plate 213. The plug-in position and plug-in structure thereof may be determined according to the removal direction of the lower base 12 and the specific contour of the lower surface of the lower base 12. In this way, when the lower base 12 is installed on the upper base 11, the first water tank 210 not only fits with the lower base 12, but also plugs and cooperates with the lower base 12, connecting the first water tank 210 and the lower base 12 as a whole. Moreover, the first water tank 210 does not affect the removal of the lower base 12, and the installation structure is reliable, stable, and practical.

[0085] like Figure 7As shown, a bending plate is further provided at one end of the support plate 213 away from the second side wall 212, and the shape of the bending plate matches the contour of the lower surface of the lower base 12. In this way, the first water tank 210 is more in contact with the lower base 12, and the supporting effect is stronger. The slot 122 is plugged into and matched with the end of the bending plate away from the support plate 213, that is, at this time, the plug-in portion 214 is the end of the bending plate away from the support plate 213, and the bending plate has the function of being in contact with the lower surface of the lower base 12, and is plugged into and matched with the slot 122, which has high reliability and strong practicality.

[0086] The advantage of such a configuration is that the pipe protection plate 2 also includes a support plate 213, and the support plate 213 is connected to the side wall of the first water tank 210. The support plate 213 is at least partially in contact with the lower bottom surface of the lower base 12, thereby avoiding that the side wall of the first water tank 210 is directly in contact with the lower bottom surface of the lower base 12. While providing positioning support for the lower base 12, the elastic space for installing the first water tank 210 and the lower base 12 is enhanced, thereby reducing the difficulty of installing the lower base 12 and the first water tank 210.

[0087] like Figure 2 As shown, the first drain pipe 410 is also included, and the first drain pipe 410 is connected to the first water tank 210. The first drain pipe 410 is used to discharge the condensed water received in the first water tank 210, and it can be directly connected to the external environment or connected to other drainage structures.

[0088] The advantage of such a configuration is that the condensed water received in the first water tank 210 can be discharged in time by providing the first drain pipe 410 , thereby preventing the condensed water from accumulating in the first water tank 210 .

[0089] like Figure 3 , Figure 8 , Fig. 9 and Fig.10 As shown, the first drain pipe 410 is connected to one end of the first water tank 210, and the end of the first water tank 210 connected to the first drain pipe 410 is inclined downward.

[0090] In some embodiments, the first drain pipe 410 is connected to one end of the first water tank 210 along the length direction. Figure 3 In this way, by setting the first water tank 210 to be inclined, the condensed water in the first water tank 210 can flow out of the first drain pipe 410 more conveniently, thereby avoiding the residue of condensed water.

[0091] like Figure 1 As shown, a second drain pipe 420 is also included, and the first water tank 210 and the second water tank 121 are respectively connected to the second drain pipe 420.

[0092] In some embodiments, both ends of the first drain pipe 410 are respectively connected to the first water tank 210 and the second drain pipe 420. A one-way valve can be provided between the first water tank 210 and the second drain pipe 420, and a one-way valve can be provided between the second water tank 121 and the second drain pipe 420, so that when the lower base 12 is installed or removed, the water in the second drain pipe 420 will not flow back to the first water tank 210 or the second water tank 121, which is highly practical.

[0093] The advantage of such a configuration is that when the lower base 12 is installed on the upper base 11, condensed water drips into the second water tank 121 and is then discharged through the second drain pipe 420; when the lower base 12 is removed from the upper base 11, condensed water drips into the first water tank 210 and is then discharged through the second drain pipe 420, thereby preventing condensed water from accumulating inside the air-conditioning indoor unit and causing pollution. The first water tank 210 does not need to be connected to the external environment with a separate drain pipe, and has a simple structure and strong practicality.

[0094] like Figure 4 As shown, a sponge 5 is also included, and the sponge 5 is located on the back side of the side wall of the first water tank 210. It should be noted that the back side of the side wall of the first water tank 210 refers to the side of the first water tank 210 opposite to the side for receiving condensed water; it should be noted that since condensed water drips into the first water tank 210, there is a certain temperature difference between the inner and outer sides of the side wall of the first water tank 210, and condensed water may be generated on the back side of the side wall of the first water tank 210. It should be noted that the sponge 5 can be only arranged on the back side of part of the side wall of the first water tank 210, which is not a limitation.

[0095] The advantage of such a configuration is that, by disposing the sponge 5 on the back side of the side wall of the first water tank 210 , it has an isolating and heat-insulating effect to a certain extent, thereby preventing water droplets from condensing on the back side of the side wall of the first water tank 210 , and is highly practical.

[0096] The cross-sectional shape of the first water tank 210 is V-shaped, concave arc-shaped or concave step-shaped. Figure 2 A plane parallel to the XZ plane.

[0097] The advantage of this arrangement is that the cross-sectional shape of the first water trough 210 is V-shaped, concave arc-shaped or concave step-shaped, the first water trough 210 has a large range for receiving condensed water, and the bottom width of the first water trough 210 is small, which is conducive to the gathering of condensed water and convenient for subsequent discharge.

[0098] Another embodiment of the present invention provides an air conditioner, the air conditioner comprising any one of the above-mentioned air conditioner indoor units. The air conditioner has the beneficial effects of the air conditioner indoor unit, which will not be described in detail here.

[0099] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
