Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, in particular to an electric control box seat and an air conditioner. Background Art

[0002] In wall-mounted air conditioner indoor units, the electronic control box is typically located at one end of the unit's interior, such as the left or right end. However, this arrangement increases the overall length of the unit, increasing the material requirements for the base, middle frame, and front panel, driving up the cost. Furthermore, it can make it difficult to position the unit indoors.

[0003] Therefore, some existing wall-mounted air conditioner indoor units place the electronic control box in front of the impeller motor, close to the main indoor space. However, this placement places the electronic control box relatively close to the indoor heat exchanger body, as well as the U-shaped tube and refrigerant branch pipe connected to the end of the indoor heat exchanger. When the air conditioner is in cooling mode, the temperatures of these components are low, as is the surrounding air temperature. Consequently, the temperature of the side wall of the electronic control box facing the indoor heat exchanger also drops due to the influence of the air. The electronic control box, which houses various electronic components and has a relatively high temperature, creates a risk of condensation when water vapor in the air encounters this side wall. Utility Model Content

[0004] A first aspect of the present invention aims to provide an electric control box seat to solve the technical problem of condensation risk on the side walls of the existing electric control box.

[0005] The electric control box seat provided in the first aspect of the present invention includes a first side wall, which is the side wall of the electric control box seat facing the indoor heat exchanger. The inner side of the first side wall is provided with a water diversion ridge, and the water diversion ridge forms an acute angle with the vertical direction.

[0006] The beneficial effects brought by the electric control box seat of the utility model are:

[0007] By arranging a water diversion ridge on the side wall of the electrical control box facing the indoor heat exchanger, so that the water diversion ridge forms an acute angle with the vertical direction, if condensation forms on the first side wall of the electrical control box base, the condensation accumulates and flows downward, which will be blocked by the water diversion ridge. The flowing condensation will flow to the lower end of the water diversion ridge, thereby avoiding contact with the circuit board and flowing along the circuit board, significantly reducing or even eliminating the risk of circuit board failure caused by condensation.

[0008] In an optional technical solution, the water-guiding ridge has a first end and a second end arranged in the front-to-back direction, and the first end is higher than the second end; the bottom wall of the electrical control box seat is provided with a continuously extending first water-retaining ridge, and the first side of the water-retaining ridge is configured to place a circuit board, and the second end is configured to guide the moving condensation to flow to the second side of the first water-retaining ridge, and the first side and the second side are opposite sides of the first water-retaining ridge.

[0009] By setting the first end of the water-guiding rib higher than the second end, moving condensate flowing downward along the first sidewall, encountering the water-guiding rib, flows along the rib and then exits the rib at the second end, flowing downward. Furthermore, a continuously extending first water-blocking rib is provided on the bottom wall of the electrical control box, with the second end configured to guide the moving condensate to the second side of the first water-blocking rib, i.e., the side facing away from the circuit board. The continuously extending first water-blocking rib blocks the flow of moving condensate from the bottom wall toward the bottom of the circuit board, thereby preventing water from contaminating the bottom of the circuit board and causing malfunctions, thereby improving the reliability of the electrical control box.

[0010] In an optional technical solution, the box seat also includes a second side wall and a third side wall, the second side wall and the third side wall are opposite to each other and are both adjacent to the first side wall, the second side wall has an inclined side wall, and the distance between the inclined side wall and the third side wall gradually decreases from top to bottom; the inclined side wall is configured to guide the moving condensation to flow to the second side of the first water retaining ridge.

[0011] By setting an inclined side wall, the condensation on the third side wall of the electric control box seat can be guided along the inclined side wall so that it flows to the bottom wall of the electric control box seat, thereby gathering the condensation on the third side wall of the electric control box seat to the bottom wall of the electric control box seat, so that the moving condensation on the bottom wall is more concentrated, which is conducive to the discharge of the condensation on the bottom wall as soon as possible, and avoids the condensation accumulating in the electric control box seat for a long time, causing excessive humidity or water corruption in the electric control box.

[0012] In an optional technical solution, the water-guiding ridge includes a first water-guiding ridge, and the second end of the first water-guiding ridge is configured to guide the moving condensation to flow to the inclined side wall.

[0013] By providing a first water-guiding ridge and enabling its second end to guide the moving condensate to the inclined side wall, this part of the moving condensate can be merged with the condensate on the inclined side wall and flow along the inclined side wall to the bottom wall of the electric control box seat.

[0014] In an optional technical solution, the water-guiding ridge includes a second water-guiding ridge, the second end of the second water-guiding ridge is configured to guide the moving condensation to flow to the inclined side wall, the second water-guiding ridge is arranged below the first water-guiding ridge, and the angle between the second water-guiding ridge and the vertical direction is smaller than the angle between the first water-guiding ridge and the vertical direction.

[0015] By arranging a second water-guiding ridge below the first water-guiding ridge so that the angle between the second water-guiding ridge and the vertical direction is smaller than that of the first water-guiding ridge, condensation in the middle and lower part of the first side wall can be guided to the inclined side wall, reducing the possibility of condensation flowing to the circuit board and improving the reliability of the electrical control box.

[0016] In an optional technical solution, the water diversion ridge further includes a third water diversion ridge, the third water diversion ridge is lower than the inclined side wall, and the second end of the third water diversion ridge is configured to guide the moving condensate flow to the second side of the first water retaining ridge.

[0017] By having the third water-guiding ridge lower than the inclined side wall, the third water-guiding ridge can be used to guide the condensation generated at the lower portion of the first side wall to the second side of the first water-blocking ridge, thereby preventing the condensation at the lower portion of the first side wall from gathering and flowing onto the circuit board, thereby improving the reliability of the electrical control box.

[0018] In an optional technical solution, the second end of the third water-guiding ridge is higher or lower than the top of the first water-retaining ridge.

[0019] By setting the second end of the third water-guiding ridge to be at the same height as or lower than the top of the first water-blocking ridge, when the moving condensate leaves the third water-guiding ridge, it is already lower than the top of the first water-blocking ridge, so it can be ensured that the moving condensate guided by the third water-guiding ridge will not fall onto the first side of the first water-blocking ridge, thereby ensuring that the circuit board will not contact the moving condensate.

[0020] In an optional technical solution, the bottom wall of the electric control box seat is provided with a continuously extending second water-blocking ridge, and the circuit board is configured to be placed on the second side of the second water-blocking ridge.

[0021] The second water retaining ridge can prevent condensation on the first side wall below the third water diversion ridge from flowing downward along the inner side of the first side wall and then flowing on the bottom wall to the bottom of the circuit board, thereby causing circuit board failure.

[0022] In an optional technical solution, the first water-blocking rib and the second water-blocking rib are arranged in parallel to form a lower slot, and the lower slot is configured to insert the circuit board.

[0023] By setting a lower slot for inserting the circuit board, the bottom of the circuit board can be limited on the first side and the second side of the circuit board, thereby fixing the circuit board to improve the stability of the bottom of the circuit board. Moreover, when the display component is installed on the circuit board, fixing the bottom of the circuit board helps the display component to stick close to the front panel of the wall-mounted air conditioner indoor unit.

[0024] A second aspect of the present invention aims to provide an air conditioner to solve the technical problem of condensation risk on the side wall of the electric control box.

[0025] The air conditioner provided in the second aspect of the present invention includes a wall-mounted air conditioner indoor unit, which includes a base, an indoor heat exchanger and an electrical control box. The indoor heat exchanger is installed on the base, one end of the indoor heat exchanger is connected to the refrigerant pipe, and the electrical control box is located on the first side of the refrigerant pipe. The electrical control box includes any one of the above-mentioned electrical control box seats.

[0026] By arranging the above-mentioned electric control box seat in the air conditioner, the air conditioner accordingly has all the advantages of the above-mentioned electric control box seat, which will not be described in detail here. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] Unless otherwise specified, the definitions of directions in this application are as follows: the front refers to the side of the wall-mounted air-conditioning indoor unit facing the main indoor space, and the back refers to the side of the wall-mounted air-conditioning indoor unit facing the wall on which it is hung. The bottom refers to the side of the wall-mounted air-conditioning indoor unit facing the ground. The top refers to the side of the wall-mounted air-conditioning indoor unit facing the roof. Left and right can be defined based on the above-mentioned front, back and bottom, that is, when the observer faces the wall on which the wall-mounted air conditioner is installed, the observer's left hand direction is the left side, and the observer's right hand direction is the right side. In addition, the inside and outside are defined based on a component in the shape of a cavity or a box body, the side of the cavity or box body facing its internal space is the inside, and the outside is the side of the cavity or box body facing its external space.

[0041] Figure 1 A schematic structural diagram of a wall-mounted air-conditioning indoor unit used in the electric control box base provided in the first embodiment of the present invention; Figure 2 This is a structural diagram of a wall-mounted air-conditioning indoor unit used for the electric control box base provided in the first embodiment of the present invention, omitting the electric control box; Figure 1 and Figure 2As shown, the wall-mounted air conditioner indoor unit includes a base 410 and an indoor heat exchanger 420. A refrigerant pipe 430 is connected to the outside of one end of the indoor heat exchanger 420. The refrigerant pipe 430 includes a U-shaped pipe 431 and a refrigerant branch pipe 432. The U-shaped pipe 431 is used to connect different areas of the indoor heat exchanger 420, thereby reversing the flow of refrigerant in the indoor heat exchanger 420. The refrigerant branch pipe 432 is used to connect the refrigerant connecting pipe 440 to different areas of the indoor heat exchanger 420. The refrigerant connecting pipe 440 is connected to the air conditioner outdoor unit. The refrigerant branch pipe 432 is used to distribute the refrigerant flowing from the air conditioner outdoor unit to different areas of the indoor heat exchanger 420 or to collect the refrigerant from different areas of the indoor heat exchanger 420 to the refrigerant connecting pipe 440.

[0042] The wall-mounted air conditioner indoor unit also includes a fan motor (not shown). A motor gland 450 is mounted on the outside of the fan motor. This gland 450 shields the fan motor from condensation on the refrigerant pipe 430 and prevents it from dripping onto the fan motor. The electrical control box can be mounted on the base 410 and the motor gland 450.

[0043] If the electrical control box is placed in front of the refrigerant pipe 430, part of the sidewall of the electrical control box will be too close to the indoor heat exchanger 420 and the refrigerant pipe 430. If the refrigerant flowing in the refrigerant pipe 430 is cool, the surrounding air temperature will also be cooler. The temperature of the sidewall of the electrical control box facing the indoor heat exchanger 420 will also drop due to the influence of the air. The electrical control box contains various electronic components, which are hot. Therefore, water vapor contained in the air in the electrical control box will condense on these sidewalls. If condensation flows onto the circuit board 300 of the electrical control box, it will affect the normal operation of the electrical control box and may cause the air conditioner to malfunction.

[0044] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following describes in detail the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0045] Example 1:

[0046] Figure 3 A schematic structural diagram of the electric control box base provided in the first embodiment of the present utility model; Figure 4 A schematic structural diagram of the electric control box base provided in the first embodiment of the present invention viewed from another direction; Figure 5 A cross-sectional view of an electric control box used in the electric control box base provided in Example 1 of the present utility model; Figure 6 This is a schematic diagram of the structure of the electric control box used in the electric control box seat provided in the first embodiment of the present invention; Figure 3-Figure 6As shown, the electric control box seat 100 provided in the first embodiment of the present invention includes a first side wall 110. The first side wall 110 is the side wall of the electric control box seat 100 facing the indoor heat exchanger 420. The inner side surface of the first side wall 110 is provided with a water diversion ridge 140, and the water diversion ridge 140 forms an acute angle with the vertical direction.

[0047] By providing a water diversion rib 140 on the side wall of the electrical control box facing the indoor heat exchanger 420, so that the water diversion rib 140 forms an acute angle with the vertical direction, if condensation forms on the first side wall 110 of the electrical control box base 100, the condensation accumulates and flows downward, which will be blocked by the water diversion rib 140. The flowing condensation will flow to the lower end of the water diversion rib 140, thereby avoiding contact with the circuit board 300 and flowing along the circuit board 300, significantly reducing or even eliminating the risk of condensation causing failure of the circuit board 300.

[0048] like Figure 1 As shown, specifically, in this embodiment, the wind turbine motor is located near the right end of the base 410, and the electrical control box is also located relatively to the right within the middle frame (not shown) of the wall-mounted air conditioner indoor unit. More specifically, the electrical control box is located relatively forward of the wall-mounted air conditioner indoor unit, while the refrigerant pipe 430 connected to the indoor heat exchanger 420 is located behind the electrical control box. Therefore, in this embodiment, the side wall of the electrical control box facing the indoor heat exchanger 420 is the left side wall of the electrical control box. That is, the first side wall 110 is the left side wall of the electrical control box in this embodiment. That is, in this embodiment, the water diversion rib 140 is disposed on the inner side of the left side wall of the electrical control box.

[0049] The electric control box includes an electric control box body, which includes an electric control box seat 100 and an electric control box cover 200. The electric control box seat 100 is the main part of the electric control box body and is used to mount a circuit board 300. In addition to the lower slot 153 described below, the electric control box seat 100 also has an upper slot 161. The circuit board 300 can be inserted into the upper slot 161 and the lower slot 153. The right edge of the circuit board 300 can be abutted by the electric control box cover 200. The circuit board 300 is arranged in a left-right direction, that is, the components on the circuit board 300 are arranged on the front side and / or the rear side of the circuit board 300. The left edge of the circuit board 300 can abut the right end surface of the water diversion ridge 140 to facilitate the positioning of the circuit board 300 from both the left and right sides.

[0050] In addition, it should be noted that those skilled in the art should be aware that the upper surface of the water diversion rib 140 should not be gradually downward in the direction of its projection from the surface on which it is provided, but can be horizontal, and preferably gradually rising in the direction of its projection. Specifically in this embodiment, the upper surface of the water diversion rib 140 should be horizontal or gradually rising from left to right.

[0051] like Figure 3-Figure 5As shown, optionally, the water-guiding ridge 140 has a first end 144 and a second end 145 arranged in the front-to-back direction, and the first end 144 is higher than the second end 145; the bottom wall 150 of the electrical control box seat 100 is provided with a continuously extending first water-retaining ridge 151, and the first side of the water-retaining ridge is configured to place the circuit board 300, and the second end 145 is configured to guide the moving condensation to flow to the second side of the first water-retaining ridge 151, and the first side and the second side are opposite sides of the first water-retaining ridge 151.

[0052] By setting the first end 144 of the water-guiding rib 140 higher than the second end 145, the moving condensate can flow downward along the first sidewall 110, encounter the water-guiding rib 140, flow along the water-guiding rib 140, and then exit the water-guiding rib 140 at the second end 145, flowing downward. Furthermore, a continuously extending first water-blocking rib 151 is provided on the bottom wall 150 of the electrical control box, with the second end 145 configured to guide the moving condensate to the second side of the first water-blocking rib 151, i.e., the side facing away from the circuit board 300. The continuously extending first water-blocking rib 151 can block the flow of the moving condensate on the bottom wall 150 toward the bottom of the circuit board 300, thereby preventing the bottom of the circuit board 300 from getting wet and causing malfunctions, thereby improving the reliability of the electrical control box.

[0053] In this embodiment, the circuit board 300 is located in the front half of the internal space of the electrical control box base 100. The second end 145 is the end of the water diversion rib 140 that is closer to the rear than the first end 144. In other words, the first end 144 is the end of the water diversion rib 140 that is closer to the front. This arrangement allows moving condensation to flow backward on the water diversion rib 140, away from the area where the circuit board 300 is located. In the following text, although the water diversion rib 140 includes a first water diversion rib 141, a second water diversion rib 142, and a third water diversion rib 143, the orientations of the first end 144 and the second end 145 of each of the first water diversion rib 141, the second water diversion rib 142, and the third water diversion rib 143 are consistent with the definition of the first end 144 and the second end 145 of the water diversion rib 140. That is, the first ends 144 of the first water diversion rib 141 , the second water diversion rib 142 and the third water diversion rib 143 are all their front ends, and the second ends 145 of the first water diversion rib 141 , the second water diversion rib 142 and the third water diversion rib 143 are all their rear ends.

[0054] In this embodiment, the first side of a component is the front side of the component or part; naturally, the second side of a component or part is the back side of the component or part.

[0055] Figure 7 This is a structural diagram of the electric control box used in the electric control box seat provided in the first embodiment of the present invention as viewed from another direction; Figure 4-Figure 7As shown, optionally, the box seat also includes a second side wall 120 and a third side wall 130, the second side wall 120 and the third side wall 130 are opposite to each other and are both adjacent to the first side wall 110, the second side wall 120 has an inclined side wall 121, and the distance between the inclined side wall 121 and the third side wall 130 gradually decreases in the direction from top to bottom; the inclined side wall 121 is configured to guide the moving condensation to flow to the second side of the first water retaining ridge 151.

[0056] By providing the inclined side wall 121, the condensation on the third side wall 130 of the electric control box seat 100 can be guided along the inclined side wall 121 so as to flow to the bottom wall 150 of the electric control box seat 100, thereby gathering the condensation on the third side wall 130 of the electric control box seat 100 to the bottom wall 150 of the electric control box seat 100, so that the moving condensation on the bottom wall 150 is more concentrated, which is conducive to the condensation on the bottom wall 150 being discharged as soon as possible, and avoiding the condensation from accumulating in the electric control box seat 100 for a long time and causing excessive humidity or water corruption in the electric control box.

[0057] In this embodiment, the third side wall 130 serves as the rear wall of the electrical control box, while the second side wall 120 serves as the front wall of the electrical control box. Specifically, in this embodiment, since the electrical control box is located in front of the refrigerant pipe 430, and the indoor heat exchanger 420 is generally in an inverted U- or V-shape, the refrigerant pipe 430 connected to the lower front portion of the indoor heat exchanger 420 is located relatively forward, and the space below the electrical control box base 100 is relatively narrow. Therefore, the lower rear wall portion 123 of the electrical control box is located further forward than the upper rear wall portion 122. Specifically, the distance between the inclined side wall 121 and the third side wall 130 gradually decreases from top to bottom. The lower rear wall portion 123 and the upper rear wall portion 122 can extend in a generally vertical direction.

[0058] Motion condensation refers to condensation that occurs when water vapor in the air condenses on the inner wall of the electric control box base 100. After condensation is generated, the inner wall of the electric control box is no longer able to absorb the condensation due to the large amount of condensation, and the larger condensed water droplets begin to move.

[0059] like Figure 4-Figure 5 As shown, optionally, the water-introducing rib 140 includes a first water-introducing rib 141 , and the second end 145 of the first water-introducing rib 141 is configured to guide the moving condensation to flow toward the inclined sidewall 121 .

[0060] By providing the first water guide rib 141 and enabling its second end 145 to guide the moving condensate to the inclined side wall 121 , this part of the moving condensate can be merged with the condensate on the inclined side wall 121 and flow along the inclined side wall 121 to the bottom wall 150 of the electric control box base 100 .

[0061] Specifically, in this embodiment, there may be multiple first water diversion ribs 141; further, in this embodiment, there may be three first water diversion ribs 141. Providing three first water diversion ribs 141 not only reduces the area of condensation received by each first water diversion rib 141, preventing the condensation flowing onto the first water diversion rib 141 from exceeding its capacity, but also serves as a reinforcing rib on the first sidewall 110, increasing the rigidity of the larger upper portion of the first sidewall 110. More specifically, the multiple first water diversion ribs 141 are arranged in parallel and vertically from top to bottom. The first water diversion ribs 141 may form an angle of 89.5° to 30° with the vertical direction, and further, may be 70°.

[0062] Since the circuit board 300 is located at the front of the internal space of the electric control box base 100, the second end 145 of the first water-guiding ridge 141 is guided to the inclined side wall 121, so that the moving condensation can flow to an area away from the circuit board 300, reducing the risk of the circuit board 300 being wetted.

[0063] like Figure 4-Figure 5 As shown, optionally, the water-guiding rib 140 includes a second water-guiding rib 142, and the second end 145 of the second water-guiding rib 142 is configured to guide the moving condensation to flow to the inclined side wall 121. The second water-guiding rib 142 is arranged below the first water-guiding rib 141, and the angle between the second water-guiding rib 142 and the vertical direction is smaller than the angle between the first water-guiding rib 141 and the vertical direction.

[0064] By arranging a second water diversion rib 142 below the first water diversion rib 141 so that the angle between the second water diversion rib 142 and the vertical direction is smaller than that of the first water diversion rib 141, condensation in the middle and lower part of the first side wall 110 can be guided to the inclined side wall 121, thereby reducing the possibility of condensation flowing to the circuit board 300 and improving the reliability of the electrical control box.

[0065] Specifically, in this embodiment, the angle between the second water-guiding rib 142 and the vertical direction is 5° to 50°, which is smaller than the angle between the first water-guiding rib 141 and the vertical direction. More specifically, the angle between the second water-guiding rib 142 and the vertical direction is 20°. The second water-guiding rib 142 can be oriented toward the lower end of the inclined sidewall 121.

[0066] In this embodiment, the second water diversion rib 142 and the first end 144 of the first water diversion rib 141 are both connected to or adjacent to the front wall of the electric control box base 100 , that is, both are adjacent to the third side wall 130 .

[0067] like Figure 4As shown, optionally, the water diversion rib 140 further includes a third water diversion rib 143 , which is lower than the inclined side wall 121 , and the second end 145 of the third water diversion rib 143 is configured to guide the moving condensate flow to the second side of the first water retaining rib 151 .

[0068] Because the third water-guiding ridge 143 is lower than the inclined side wall 121, the third water-guiding ridge 143 can be used to guide the condensation generated at the lower portion of the first side wall 110 to the second side of the first water-blocking ridge 151, thereby preventing the condensation at the lower portion of the first side wall 110 from gathering and flowing onto the circuit board 300, thereby improving the reliability of the electrical control box.

[0069] In this embodiment, the second end 145 of the third water diversion rib 143 is located at the rear side of the first water retaining rib 151, while the first end 144 of the third water diversion rib 143 is located at the first side of the second water retaining rib 152 described later, that is, the front side of the second water retaining rib 152. In this embodiment, the angle between the third water diversion rib 143 and the vertical direction can be 30° to 70°, and more specifically, the third water diversion rib 143 can be 45°.

[0070] In this embodiment, the second end 145 of the third water-guiding ridge 143 can be close to the rear wall lower portion 123 , thereby preventing the water flow on the inclined side wall 121 from flowing over the first water-blocking ridge 151 and affecting the circuit board 300 when the water flow is too large.

[0071] like Figure 4 As shown, optionally, the second end 145 of the third water-introducing rib 143 is higher or lower than the top of the first water-blocking rib 151 .

[0072] By setting the second end 145 of the third water-guiding ridge 143 to be at the same height as or lower than the top of the first water-blocking ridge 151, when the moving condensate leaves the third water-guiding ridge 143, it is already lower than the top of the first water-blocking ridge 151. Therefore, it can be ensured that the moving condensate guided by the third water-guiding ridge 143 will not fall onto the first side of the first water-blocking ridge 151, thereby ensuring that the circuit board 300 will not come into contact with the moving condensate.

[0073] like Figure 3-Figure 5 As shown, optionally, the bottom wall 150 of the electric control box seat 100 is provided with a continuously extending second water-blocking ridge 152 , and the circuit board 300 is configured to be placed on a second side of the second water-blocking ridge 152 .

[0074] The second water-blocking rib 152 can prevent condensation on the first side wall 110 below the third water-introducing rib 143 from flowing downward along the inner surface of the first side wall 110 and then flowing on the bottom wall 150 to the bottom of the circuit board 300, thereby preventing the circuit board 300 from malfunctioning.

[0075] Specifically, in this embodiment, the second water retaining rib 152, the circuit board 300, and the first water retaining rib 151 are arranged in sequence from front to back, that is, the circuit board 300 is placed on the rear side of the second water retaining rib 152. The first water retaining rib 151 and the second water retaining rib 152 are both connected to the first side wall 110 to prevent condensation on the first side wall 110 from flowing to the bottom of the circuit board 300.

[0076] like Figure 3-Figure 5 As shown, optionally, the first water-blocking rib 151 and the second water-blocking rib 152 are arranged in parallel and form a lower slot 153 , and the lower slot 153 is configured to insert the circuit board 300 .

[0077] By setting a lower slot 153 for inserting the circuit board 300, the bottom of the circuit board 300 can be limited on the first side and the second side of the circuit board 300, thereby fixing the circuit board 300 to improve the stability of the bottom of the circuit board 300. Moreover, when a display component is installed on the circuit board 300, fixing the bottom of the circuit board 300 is conducive to the display component being close to the front panel of the wall-mounted air-conditioning indoor unit.

[0078] Specifically, the first water-blocking rib 151 and the second water-blocking rib 152 form a lower slot 153 for inserting the circuit board 300, which means that at least one side surface of the bottom of the circuit board 300 will contact the first water-blocking rib 151 or the second water-blocking rib 152, limiting the bottom of the circuit board 300 in at least one direction in the front-to-back direction. Alternatively, the first water-blocking rib 151 and the second water-blocking rib 152 may both contact the bottom of the circuit board 300, limiting its position in both directions in the front-to-back direction.

[0081] By arranging the electric control box seat 100 in the air conditioner, the air conditioner accordingly has all the advantages of the electric control box seat 100, which will not be described in detail here.
