Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and more specifically, to a wall-mounted air conditioner indoor unit and an air conditioner. Background Art

[0002] In a wall-mounted air conditioner indoor unit, an electric control box is usually arranged at the end of the internal space of the wall-mounted air conditioner indoor unit, such as the left end or the right end. However, with such an arrangement, the overall length of the wall-mounted air conditioner indoor unit will increase. On the one hand, it will lead to an increase in the materials used for the base, middle frame and panel of the air conditioner, increasing the cost of the air conditioner. On the other hand, it will also make it difficult to place the air conditioner in the indoor space.

[0003] Therefore, some existing wall-mounted air conditioner indoor units arrange the electric control box in front of the wind wheel motor, that is, on the side close to the main indoor space. However, with such an arrangement, the connection position between the electric control box and the component on which it is installed is not easily directly observable during assembly, which may reduce the operation convenience and increase the production time. Summary of the Utility Model

[0004] The purpose of the first aspect of the present utility model is to provide a wall-mounted air conditioner indoor unit to solve the technical problem of difficult assembly of the existing electric control box.

[0005] The wall-mounted air conditioner indoor unit provided by the first aspect of the present utility model includes a motor gland and an electric control box. The motor gland has a first connection block, and the electric control box has a second connection block. The first connection block and the second connection block are connected by a concave-convex matching method. The first connection block further forms a first positioning surface, and the electric control box further has an electric control box body and a third connection block protruding from the electric control box body. The third connection block forms a second positioning surface, and the first positioning surface is adjacent to the second positioning surface.

[0006] The beneficial effect brought by the wall-mounted air conditioner indoor unit of the present utility model is:

[0007] By providing a second positioning surface on the third connection block of the electric control box and a first positioning surface on the first connection block, during the process of installing the second connection block of the electric control box on the first connection block of the motor gland, the first positioning surface and the second positioning surface can be made to be adjacent and fit first, and then the electric control box is moved while maintaining the fitting state of the two. The relative position accuracy between the two is significantly improved, and then the first connection block and the second connection block with concave-convex matching are inserted, and the insertion process becomes very smooth, thereby improving the assembly efficiency.

[0008] In an optional technical solution, the first positioning surface is located on the vertical end surface of the first connection block.

[0009] The first positioning surface is arranged on the vertical end surface of the first connecting block. When installing the electric control box, the electric control box can be horizontally moved first so that the third positioning surface fits with the first positioning surface to achieve the positioning of the electric control box and the motor gland in a certain horizontal direction. Then, the electric control box is moved in the vertical plane so that the first connecting block and the second connecting block form a concave-convex matching structure, thereby improving the assembly efficiency.

[0010] In an alternative technical solution, the second connecting block includes an insertion convex block. The insertion convex block is inclined relative to the first side wall, and the insertion convex block gradually moves away from the first side wall in the downward direction; the first side wall is the side wall of the electric control box body facing the first connecting block; the first connecting block is provided with a receiving cavity for receiving and matching the insertion convex block, and a second notch is provided on a side of the receiving cavity facing away from the first side wall for the insertion convex block to pass through.

[0011] By setting the insertion convex block to gradually move away from the first side wall in the downward direction relative to the first side wall, when the first connecting block and the second connecting block are installed, the electric control box can slide downward relative to the motor gland. Since the insertion convex block is inclined, when the insertion convex block contacts the receiving cavity, it can automatically align to ensure that the first connecting block and the second connecting block can be installed in place, improving the installation efficiency. And by providing a first notch on a side of the receiving cavity facing away from the first side wall, the inclined insertion convex block can enter the receiving cavity.

[0012] In an alternative technical solution, the electric control box further includes a connecting plate and a first support rib. The connecting plate connects the top of the insertion convex block and the first side wall; the first support rib is perpendicular to the first side wall, and the first support rib connects the insertion convex block and the first side wall; a second notch is provided on a side of the receiving cavity close to the first side wall for receiving the first support rib.

[0013] By providing a connecting plate to connect the top of the insertion convex block and the first side wall, the connection stiffness between the top of the insertion convex block and the first side wall can be improved. By providing a first support rib to connect the first side wall and the insertion convex block, the connection stiffness between the middle and lower parts of the insertion convex block and the first side wall can be improved. And by providing a second notch on a side of the receiving cavity close to the first side wall to receive the first support rib, interference between the first support rib and this side of the receiving cavity can be avoided, preventing the insertion convex block from being affected when inserted into the receiving cavity.

[0014] In an alternative technical solution, a first chamfering portion is provided at an end of the second notch facing the first side wall.

[0015] By setting a first chamfered portion at one end of the second notch facing the first side wall, when the insertion protrusion moves horizontally toward the accommodating cavity, the lower part of the first support rib can be guided by the first chamfered portion, thereby facilitating the first support rib to enter the second notch, thereby reducing the difficulty of operation and improving the operating efficiency.

[0016] In an optional technical solution, a second chamfered portion is provided at the upper end of the second notch.

[0017] By arranging a second chamfered portion at the upper end of the second notch, the local height range of the second notch is made larger at the top and smaller at the bottom, which facilitates the downward movement of the electric control box, so that when the plug-in protrusion is inserted into the accommodating cavity, the first supporting rib can be guided by the second chamfered portion, thereby facilitating the first supporting rib to enter the second notch, and also facilitating the plug-in protrusion to enter the accommodating cavity, which can reduce the difficulty of operation and improve the operating efficiency.

[0018] In an optional technical solution, the first connecting block includes a first end plate and a plurality of second supporting ribs, the second supporting ribs are perpendicular to and connected to the first end plate, and the side of the second supporting ribs facing away from the first end plate is adjacent to the second connecting block.

[0019] The first end plate and a plurality of second supporting ribs are used to form the first connecting block. On the one hand, the weight and material usage of the first connecting block can be reduced. On the other hand, the material thickness of each part of the motor gland can be made as consistent as possible. When the injection molding material solidifies, the solidification time of the material is similar, which is conducive to making the surface of the injection molded product flatter and smoother. In addition, since the surface formed by the edges of the plurality of second supporting ribs away from the first end plate is flatter than the first end plate, that is, the edge of one side of the second supporting rib away from the first end plate is used to fit the second connecting block, it is conducive to improving the positioning accuracy.

[0020] In an optional technical solution, the second connecting block includes a second end plate and a plurality of third supporting ribs, wherein the third supporting ribs are perpendicular to and connected to the second end plate, and the side of the third supporting ribs facing away from the second end plate is adjacent to the first connecting block.

[0021] The second end plate and a plurality of third support ribs are used to form the first connection block. On the one hand, the weight and material usage of the second connection block can be reduced. On the other hand, the thickness of the materials of each part of the electric control box can be made as consistent as possible. When the injection molding material solidifies, the solidification time of the materials is similar, which is conducive to making the surface of the injection molded product flatter and smoother. In addition, since the surface formed by the edges of the plurality of third support ribs away from the second end plate is flatter than the second end plate, that is, the edge of one side of the third support rib away from the second end plate is used to fit with the second connection block, it is conducive to improving the positioning accuracy.

[0022] In an alternative technical solution, the second connection block is located at the upper part of the electric control box; the electric control box further includes a connection ear plate located at the bottom of the electric control box, and a male threaded connector passes through the connection ear plate, and the male threaded connector is threadedly connected to a threaded hole on the base.

[0023] By arranging the second connection block at the upper part of the electric control box and arranging a connection ear plate at the bottom of the electric control box for the male threaded connector to pass through and connect to the base, it can be ensured that the two positions where the electric control box is fixed - the second connection block and the connection ear plate are far apart, so as to cover a large range of the height of the electric control box, reduce the proportion of the area of the electric control box outside the two connection positions, and improve the installation stiffness of the electric control box.

[0024] The purpose of the second aspect of the present utility model is to provide an air conditioner to solve the technical problem of difficult assembly of the electric control box.

[0025] The air conditioner provided in the second aspect of the present utility model includes an air conditioner outdoor unit and the wall-mounted air conditioner indoor unit according to any one of the above, and the air conditioner outdoor unit is connected to the wall-mounted air conditioner indoor unit through a refrigerant connection pipe.

[0026] By arranging the above wall-mounted air conditioner indoor unit in the air conditioner, correspondingly, the air conditioner has all the advantages of the above wall-mounted air conditioner indoor unit, which will not be elaborated here one by one. Description of the Drawings

[0055] Embodiment 1:

[0056] Figure 1 Schematic diagram of the structure of the wall-mounted air conditioner indoor unit provided in Embodiment 1; Figure 2 Schematic diagram of another direction of the wall-mounted air conditioner indoor unit provided in Embodiment 1;Figure 3 Partial perspective cross-sectional view of the wall-mounted air conditioner indoor unit provided for Example 1; Figure 4 Partial perspective cross-sectional view of the wall-mounted air conditioner indoor unit provided for Example 1 as viewed from another direction; Figure 5 Partial structural schematic diagram of the wall-mounted air conditioner indoor unit provided for Example 1 with the box cover omitted; Figure 6 Partial structural schematic diagram of the wall-mounted air conditioner indoor unit provided for Example 1 with the electronic control box omitted; Figure 7 Front view of the wall-mounted air conditioner indoor unit provided for Example 1 with the electronic control box omitted; As Figures 1 - 7 shown, the wall-mounted air conditioner indoor unit provided for Example 1 includes a motor gland 200 and an electronic control box 100. The motor gland 200 has a first connecting block 210, and the electronic control box 100 has a second connecting block 110. The first connecting block 210 and the second connecting block 110 are connected by means of concave-convex cooperation; The first connecting block 210 further forms a first positioning surface 211. The electronic control box 100 further has an electronic control box body 120 and a third connecting block 130 protruding from the electronic control box body 120. The third connecting block 130 forms a second positioning surface 131, and the first positioning surface 211 is adjacent to the second positioning surface 131.

[0057] By providing the second positioning surface 131 on the third connecting block 130 of the electronic control box 100 and the first positioning surface 211 on the first connecting block 210, during the process of installing the second connecting block 110 of the electronic control box 100 on the first connecting block 210 of the motor gland 200, the first positioning surface 211 and the second positioning surface 131 can be made to be adjacent and fit first, and then the electronic control box 100 is moved while maintaining the state of their fitting. The relative position accuracy between the two is significantly improved, and then the first connecting block 210 and the second connecting block 110 with concave-convex cooperation are inserted, and the insertion process becomes very smooth, thereby improving the assembly efficiency.

[0058] In this embodiment, the wall-mounted air conditioner indoor unit includes a base 310, a middle frame (not shown in the figure), and a front panel (not shown in the figure). When the wall-mounted air conditioner indoor unit is installed indoors, it is necessary to first fix the wall-mounted board (not shown in the figure) on the wall, for example, nailed to the wall, and then hang the main body of the air conditioner indoor unit on the wall-mounted board. The base 310 is the part of the wall-mounted air conditioner indoor unit for mounting on the wall-mounted board. The middle frame is installed on the base 310, and a heat exchanger 320 is provided inside the middle frame. The heat exchanger 320 is installed on the base 310. The front panel is installed on the middle frame. The electronic control box 100 is located between the motor gland 200 and the middle frame.

[0059] Among them, in this embodiment, the first connection block 210 has a concave structure, and the second connection block 110 has a convex structure. In this embodiment, the example of inserting the convex structure of the second connection block 110 into the concave structure of the first connection block 210 is used for illustration. Of course, in other implementation manners, the convex structure may be provided on the first connection block 210, and the concave structure may be provided on the second connection block 110.

[0060] Figure 8 It is a schematic structural diagram of the electronic control box in the wall-mounted air conditioner indoor unit provided in the first embodiment; Figure 9 It is a schematic structural diagram of the electronic control box in another direction of the wall-mounted air conditioner indoor unit provided in the first embodiment; As Figure 8 and Figure 9 shown, in this embodiment, the electronic control box 100 includes a box base 121 and a box cover 122, and the box cover 122 is closed on the box base 121 from right to left. Among them, the second connection block 110 is provided on the rear side surface of the box base 121, and the third connection block 130 is also provided in the area on the left side of the rear side surface of the box cover 122.

[0061] As Figure 7 shown, optionally, the first positioning surface 211 is located on the vertical end surface of the first connection block 210.

[0062] By setting the first positioning surface 211 on the vertical end surface of the first connection block 210, when installing the electronic control box 100, the electronic control box 100 can be horizontally moved first so that the third positioning surface 219 fits with the first positioning surface 211 to achieve the positioning of the electronic control box 100 and the motor gland 200 in a certain horizontal direction, and then the electronic control box 100 is moved in the vertical plane so that the first connection block 210 and the second connection block 110 form a concave-convex matching structure, thereby improving the assembly efficiency.

[0063] Among them, the vertical end surface refers to the substantially vertical surface of the first connection block 210. For example, this vertical end surface can form an angle of less than 10° with the vertical direction. Specifically, in this embodiment, the vertical end surface is the right end surface of the first connection block 210.

[0064] In this embodiment, taking the electronic control box 100 being located in the right half of the wall-mounted air conditioner indoor unit as an example for introduction, and the motor gland 200 for shielding the motor is fixedly connected to the base 310. In this embodiment, the electronic control box 100 is located between the motor gland 200 and the middle frame. Generally speaking, the second connection block 110 is located on the back surface of the electronic control box 100, that is, the rear surface of the electronic control box 100. During installation, it is difficult for the operator to observe and accurately control the relative position between the second connection block 110 and the motor gland 200. In this embodiment, the first positioning surface 211 is located on the right side surface of the first connection block 210, the third connection block 130 is located on the right side of the electronic control box 100, and the left side surface of the third connection block 130 is the second positioning surface 131.

[0065] When the protruding structure of the second connecting block 110 needs to be inserted into the recessed structure of the first connecting block 210, first move the electric control box 100 from right to left so that the left side surface of the third connecting block 130 - the second positioning surface 131 fits against the right end surface of the second connecting block 110, aligning the first connecting block 210 and the second connecting block 110 in the horizontal direction. Then move the electric control box 100 in the vertical plane, so as to smoothly insert the protruding structure of the first connecting block 210 into the recessed structure of the second connecting block 110.

[0066] Figure 10 Schematic diagram of the structure of the electric control box in another direction in the wall - mounted air - conditioner indoor unit provided in the first embodiment; Figure 11 Cross - sectional view of the electric control box in the wall - mounted air - conditioner indoor unit provided in the first embodiment; Figure 12 Right - view of the box base in the wall - mounted air - conditioner indoor unit provided in the first embodiment; Figures 13 - 15 Schematic diagrams of the structure of the box cover in different directions in the wall - mounted air - conditioner indoor unit provided in the first embodiment; As Figures 2 - 5 、 Figures 9 - 11 、 Figures 13 - 16 shown, optionally, the second connecting block 110 includes an insertion convex block 111, the insertion convex block 111 is inclined relative to the first side wall 150, and the insertion convex block 111 gradually moves away from the first side wall 150 in the downward direction; the first side wall 150 is the side wall of the electric control box body 120 facing the first connecting block 210; the first connecting block 210 is provided with a receiving cavity 212 for receiving and matching the insertion convex block 111, and a first notch 213 is provided on the side of the receiving cavity 212 facing away from the first side wall 150, and the first notch 213 is used for the insertion convex block 111 to pass through.

[0067] By setting the insertion convex block 111 to gradually move away from the first side wall 150 in the downward direction relative to the first side wall 150, when the first connecting block 210 and the second connecting block 110 are installed, the electric control box 100 can slide downward relative to the motor gland 200. Since the insertion convex block 111 is inclined, after the insertion convex block 111 contacts the receiving cavity 212, it can be automatically aligned to ensure that the first connecting block 210 and the second connecting block 110 can be installed in place, improving the installation efficiency. And by providing the first notch 213 on the side of the receiving cavity 212 facing away from the first side wall 150, the inclined insertion convex block 111 can enter the receiving cavity 212.

[0068] Among them, in this embodiment, when observed from right to left, the first connecting block 210 is generally triangular or trapezoidal, both the triangle and the trapezoid are in a state of being smaller at the top and larger at the bottom, and the front side edges of the triangle and the trapezoid are approximately vertical. The receiving cavity 212 is arranged at a position slightly behind the top of the triangle or trapezoid.

[0069] In this embodiment, the first side wall 150 is a partial side wall of the rear side of the electric control box 100. After the electric control box 100 is installed in place, the first side wall 150 is also in an approximately vertical state. The insertion bump 111 is arranged at the upper part of the first side wall 150, so as to limit the position of the electric control box 100 starting from the upper part of the first side wall 150, thereby improving the installation stiffness of the electric control box 100. Among them, the front surface of the first connection block 210 can be the third positioning surface 219, and the rear surface of the first side wall 150 can be the fourth positioning surface 151. When the third positioning surface 219 is adjacent to the fourth positioning surface 151, the positioning of the electric control box 100 in the front-back direction relative to the motor gland 200 can be realized. However, in this embodiment, since the insertion bump 111 is arranged to incline downward, as long as the insertion bump 111 can be inserted into the receiving cavity 212, the electric control box 100 can be spontaneously installed in place during the downward movement of the electric control box 100 relative to the motor gland 200, without the third positioning surface 219 and the fourth positioning surface 151 having to be adjacent and fitted.

[0070] Of course, in another implementation manner, if the insertion bump 111 is vertically downward, after the first positioning surface 211 and the second positioning surface 131 are adjacent and fitted to realize the horizontal positioning in the left-right direction, the third positioning surface 219 and the fourth positioning surface 151 are adjacent and fitted, and the horizontal positioning in the front-back direction can be realized. Then, the horizontal position of the insertion bump 111 relative to the receiving cavity 212 can be determined. By moving the electric control box 100 downward, the insertion bump 111 can be smoothly inserted into the receiving cavity 212 to install the electric control box 100 on the motor gland 200, which can improve the installation efficiency.

[0071] As Figure 3 、 Figure 4 and Figures 9 - 11 、 Figures 13 - 15 shown, optionally, the electric control box 100 further includes a connecting plate 112 and a first support rib 113. The connecting plate 112 connects the top of the insertion bump 111 and the first side wall 150; the first support rib 113 is perpendicular to the first side wall 150, and the first support rib 113 connects the insertion bump 111 and the first side wall 150; a second notch 214 is provided on one side of the receiving cavity 212 close to the first side wall 150, and the second notch 214 is used to receive the first support rib 113.

[0072] By providing a connecting plate 112 to connect the top of the plug-in protrusion 111 and the first side wall 150, the connection rigidity between the top of the plug-in protrusion 111 and the first side wall 150 can be improved, and by providing a first supporting rib 113 to connect the first side wall 150 and the plug-in protrusion 111, the connection rigidity between the middle and lower part of the plug-in protrusion 111 and the first side wall 150 can be improved. A second notch 214 is provided on one side of the accommodating cavity 212 close to the first side wall 150 to accommodate the first supporting rib 113, so as to avoid the first supporting rib 113 interfering with this side of the accommodating cavity 212 and affecting the insertion of the plug-in protrusion 111 into the accommodating cavity 212.

[0073] In this embodiment, the first support rib 113 can be roughly trapezoidal, wherein the bottom of the first support rib 113, the end connected to the plug-in protrusion 111 is higher than the end connected to the first side wall 150; and a fourth support rib 114 is provided on the edge of one side where the first support rib 113 is connected to the first side wall 150. The fourth support rib 114 is a right triangle, and multiple fourth support ribs 114 are arranged in the vertical direction on both sides of the first support rib 113. In addition, above the connecting plate 112, the electric control box 100 is also provided with a wire hole plate 140, which is used to fix part of the cables led out of the electric control box 100. The wire hole plate 140 can also play a supporting role for the connecting plate 112, thereby improving the rigidity of the connecting plate 112. The connecting plate 112 is perpendicular to the extension direction of the plug-in protrusion 111. In this embodiment, it can cover the entire area of ​​the top of the plug-in protrusion 111.

[0074] Figures 17 - 21 The schematic diagram of the structure of the motor gland in the wall-mounted air conditioner indoor unit provided in the first embodiment from different directions; Figure 6 , Figure 7 and Figures 16 - 21 As shown, optionally, a first chamfered portion 215 is provided at one end of the second notch 214 facing the first side wall 150 .

[0075] By setting a first chamfered portion 215 at one end of the second notch 214 facing the first side wall 150, when the insertion protrusion 111 moves horizontally toward the accommodating cavity 212, the lower part of the first support rib 113 can be guided by the first chamfered portion 215, thereby facilitating the first support rib 113 to enter the second notch 214, thereby reducing the difficulty of operation and improving the operating efficiency.

[0076] like Figure 6 , Figure 7 and Figures 16 - 21 As shown, optionally, a second chamfered portion 216 is provided at the upper end of the second notch 214 .

[0077] By providing a second chamfered portion 216 at the upper end of the second notch 214, the local height range of the second notch 214 is made to be larger at the top and smaller at the bottom, facilitating the downward movement of the electronic control box 100. When the insertion bump 111 is inserted into the accommodation cavity 212, the first support rib 113 can be guided by the second chamfered portion 216, thus facilitating the entry of the first support rib 113 into the second notch 214 and also facilitating the entry of the insertion bump 111 into the accommodation cavity 212. This can reduce the operation difficulty and improve the operation efficiency.

[0078] In addition, at the bottom of the insertion bump 111, a third chamfered portion 117 is also provided. The third chamfered portion 117 is provided at the bottom of the left and right end faces of the insertion bump 111, thus facilitating the insertion of the insertion bump 111 into the accommodation cavity 212.

[0079] Such as Figures 3 - 5 、 Figure 7 and Figures 16 - 21 shown, optionally, the first connection block 210 includes a first end plate 217 and a plurality of second support ribs 218. The second support ribs 218 are perpendicular to the first end plate 217 and are connected to the first end plate 217. The side surface of the second support rib 218 facing away from the first end plate 217 is adjacent to the second connection block 110.

[0080] Adopting the form of the first connection block 210 composed of the first end plate 217 and a plurality of second support ribs 218 can, on the one hand, reduce the weight and material usage of the first connection block 210, and on the other hand, can also make the material thickness of each part of the motor gland 200 as consistent as possible. When the injection molding material solidifies, the solidification time of the material is similar, which is beneficial to making the surface of the injection molded product smoother and flatter. In addition, since the surface formed by the edges of the plurality of second support ribs 218 facing away from the first end plate 217 is flatter than the first end plate 217, that is, using the side edge of the second support rib 218 facing away from the first end plate 217 to fit with the second connection block 110 is beneficial to improving the positioning accuracy.

[0081] Specifically, in this embodiment, the first end plate 217 can be generally triangular or trapezoidal in shape, and some of the second support ribs 218 can form the front and rear surfaces of the first connection block 210, and the remaining second support ribs 218 intersect horizontally and vertically to support the first end plate 217 in the horizontal direction, thus comprehensively supporting the first end plate 217.

[0082] Such as Figure 9 、 Figure 10 and Figures 13 - 15As shown, optionally, the second connection block 110 includes a second end plate 132 and a plurality of third support ribs 133. The third support ribs 133 are perpendicular to the second end plate 132 and connect the second end plate 132. The side of the third support ribs 133 facing away from the second end plate 132 is adjacent to the first connection block 210.

[0083] Adopting the form of the second end plate 132 and a plurality of third support ribs 133 to form the first connection block 210 can, on the one hand, reduce the weight and material usage of the second connection block 110, and on the other hand, make the material thickness of each part of the electric control box 100 as consistent as possible. When the injection molding material solidifies, the solidification time of the material is similar, which is beneficial to making the surface of the injection molded product smoother and flatter. In addition, since the surface formed by the edges of the plurality of third support ribs 133 facing away from the second end plate 132 is flatter than the second end plate 132, that is, using the side edge of the third support ribs 133 facing away from the second end plate 132 to fit with the second connection block 110 is beneficial to improving the positioning accuracy.

[0084] As Figures 2 - 5 and Figures 9 - 15 shown, optionally, the second connection block 110 is located at the upper part of the electric control box 100; the electric control box 100 further includes a connection ear plate 123 located at the bottom of the electric control box 100. A male threaded connector passes through the connection ear plate 123, and the male threaded connector is threadedly connected to the threaded hole 311 on the base 310.

[0085] By arranging the second connection block 110 at the upper part of the electric control box 100 and arranging the connection ear plate 123 at the bottom of the electric control box 100 for the male threaded connector to pass through and connect to the base 310, the two positions where the electric control box 100 is fixed - the second connection block 110 and the connection ear plate 123 - can be far apart, covering a large range in the height of the electric control box 100, reducing the proportion of the area of the electric control box 100 that is not between the two connection positions, and improving the installation stiffness of the electric control box 100.

[0086] Among them, in this embodiment, the connection ear plate 123 is connected to the bottom of the front surface of the electric control box 100, and the connection ear plate 123 is also connected to the electric control box 100 through a fifth support rib 124 to improve the connection stiffness of the connection ear plate 123.

[0087] The operating principle of this embodiment is:

[0088] In this embodiment, the electric control box 100 is located at the right end of the internal space of the wall-mounted air conditioner indoor unit and is located between the motor gland 200 and the front part of the middle frame. The electric control box 100 is installed on the motor gland 200, and the motor gland 200 is installed on the base 310.

[0089] When the electric control box 100 needs to be installed on the motor gland 200, first keep the electric control box 100 at a height higher than the position where it is installed on the motor gland 200, and move the electric control box 100 from right to left so that the first positioning surface 211 contacts the second positioning surface 131, thereby ensuring the relative position of the electric control box 100 and the motor gland 200 in the left-right direction. Then, move the first side wall 150 of the electric control box 100 backward and / or downward so that it approaches the first connecting block 210, and guide the first support rib 113 through the first chamfered portion 215 and / or the second chamfered portion 216 into the second notch 214, thereby realizing the relative positioning of the insertion bump 111 and the receiving cavity 212. Since the rear part of the receiving cavity 212 is the first notch 213, when the insertion bump 111 moves from top to bottom, it can smoothly enter the receiving cavity 212.

[0090] After the insertion bump 111 has entered the receiving cavity 212, the through hole of the connecting ear plate 123 can be aligned with the threaded hole 311, and the connecting ear plate 123 and the threaded hole 311 on the base 310 are fixed by a male threaded connecting member, fixing the electric control box 100 at two positions, the upper and the bottom, which is beneficial to improving the installation rigidity of the electric control box 100.
