Description

Technical Field

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

[0002] In a wall-mounted air conditioner indoor unit, the 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, such an arrangement will increase the overall length of the wall-mounted air conditioner indoor unit. 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, when the electric control box is arranged here, since the front lower part of the internal space of the wall-mounted air conditioner indoor unit is the air outlet mechanism, the height of the electric control box is limited. Moreover, since the position of the electric control box utilizes the space in front of the wind wheel motor, the left-right width of the electric control box is also limited. Therefore, it is difficult to layout the circuit board and wiring terminals in the electric control box. Summary of the Utility Model

[0004] The first object of the utility model is to provide an electric control box to solve the technical problem that the existing electric control box is difficult to layout due to height or width.

[0005] The electric control box provided by the utility model includes a box base and a circuit board. The circuit board is vertically installed on the box base. A plurality of wiring terminals are arranged on the circuit board. The plurality of wiring terminals include a first wiring terminal and a second wiring terminal. The wiring direction of the insertion port of the first wiring terminal is a horizontal direction parallel to the circuit board, and the wiring direction of the insertion port of the second wiring terminal is a vertical direction.

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

[0007] By arranging some of the wiring terminals to insert wires in the vertical direction and some of the wiring terminals to insert wires in the horizontal direction parallel to the circuit board, the number of wiring terminals that need to be arranged in each direction can be reduced, thereby reducing the size in each direction. This is beneficial to reducing the height or width of the electric control box, facilitating the layout of the electric control box inside the wall-mounted air conditioner indoor unit, and facilitating the electric control box to be arranged in front of the wind wheel motor, thereby reducing the overall size of the wall-mounted air conditioner indoor unit.

[0008] In an optional technical solution, a first slot is provided on the bottom wall of the box base, and the bottom of the circuit board is inserted into the first slot.

[0009] By providing a first slot on the bottom wall of the box base, it is beneficial to position the bottom of the circuit board, thereby improving the installation stability of the circuit board. Moreover, installing the circuit board by means of plugging can improve the installation efficiency compared with directly installing through male threaded connectors and reduce the extrusion on a local part of the circuit board.

[0010] In an alternative technical solution, a second slot is provided on the top wall of the box base, the second slot is parallel to the first slot, and the top of the circuit board is plugged into the second slot.

[0011] By providing a second slot on the top wall of the box base, it is beneficial to cooperate with the first slot on the bottom wall of the circuit board to position both the upper and lower edges of the circuit board, so that the circuit board can maintain its position in the front-rear direction and pitch, thereby improving the installation stiffness of the circuit board.

[0012] In an alternative technical solution, the electric control box includes a box cover, the box cover is fastened and fixedly connected to the box base in the horizontal direction, and positioning posts are further provided on the inner surface of the side wall of the box cover, and the positioning posts abut against the side edge of the circuit board.

[0013] By fastening and fixedly connecting the cover to the box base in the horizontal direction, the positioning posts provided on the box cover can be used to abut against the side edge of the circuit board, so as to apply a force to the side edge of the circuit board in the horizontal direction, and cooperate with the first slot or the first slot and the second slot to fix the circuit board, prevent the circuit board from sliding left and right in the electric control box, and avoid abnormal noises caused by the movement and collision of the circuit board in the electric control box and damage to the electronic components on the circuit board.

[0014] In an alternative technical solution, the positioning posts include upper positioning posts and lower positioning posts, the upper positioning posts abut against the upper part of the side edge of the circuit board, and the lower positioning posts abut against the lower part of the side edge of the circuit board.

[0015] By providing upper positioning posts to abut against the upper part of the side edge of the circuit board and lower positioning posts to abut against the lower part of the side edge of the circuit board, it is possible to achieve separate abutment against the upper and lower parts of the side edge of the circuit board, and the abutment positions can be closer to the first slot and the second slot, so as to jointly fix the upper and lower parts of the circuit board by using the frictional force of abutting against the side edge of the circuit board and the front-rear limiting effect of the first slot and the second slot.

[0016] In an alternative technical solution, a first notch is provided on the bottom wall of the box base, the first notch is correspondingly arranged with the second terminal, and the bottom wall of the box cover covers a part of the first notch.

[0017] By providing a first notch portion on the bottom wall of the box base corresponding to the second terminal, and using the bottom wall of the box cover to block a part of the first notch portion, the cable inserted into the second terminal is constrained and led out from the lower part of the electric control box, without occupying the horizontal side space of the electric control box, which is conducive to the arrangement of the electric control box in a narrow space.

[0018] In an alternative technical solution, a first cable retaining hook is provided on the box base, and the first cable retaining hook is lower than the first notch portion.

[0019] By providing the first cable retaining hook, the cable led out from the first notch portion can be constrained, preventing the cable from being scattered or having too large a movement range, improving the service life of the cable. Also, the cable can be constrained before and during the closing of the box cover to avoid being clamped between the end face of the box base and the box cover, interfering with the closing of the box cover.

[0020] In an alternative technical solution, the upper surface of the bottom wall of the box cover is lower than the lower surface of the bottom wall of the box base.

[0021] By setting the upper surface of the bottom wall of the box cover lower than the lower surface of the bottom wall of the box base, a space is formed between the bottom wall of the box cover and the bottom wall of the box base, through which the cable led out from the insertion port of the second insertion terminal can be led out backward. On the one hand, the length of this part of the cable can be reduced, saving cable materials. On the other hand, these cables do not need to be hooked by the first cable retaining hook, reducing the sharpness of cable bending, which is beneficial to improving the service life of these cables.

[0022] In an alternative technical solution, a second cable retaining hook is further provided on the box base, and the second cable retaining hook is higher than the bottom wall of the box cover and lower than the bottom wall of the box base.

[0023] By setting the second cable retaining hook higher than the bottom wall of the box cover and lower than the bottom wall of the box base, the cable led out from the first terminal can be hooked, preventing it from moving horizontally to between the side end face of the box base and the box cover and interfering with the box cover being fastened to the box base, thereby improving the installation efficiency.

[0024] The second object of the present utility model is to provide an air conditioner to solve the technical problem that the electric control box is difficult to layout due to its height or width.

[0025] The air conditioner provided by the present utility model includes a wall-mounted air conditioner indoor unit, the wall-mounted air conditioner indoor unit includes a base, a wind wheel motor, and the electric control box according to any one of the above, the wind wheel motor is installed on the base, and the electric control box is located in front of the wind wheel motor.

[0026] By providing the above electric control box in the air conditioner, correspondingly, the air conditioner has all the advantages of the above electric control box, which will not be elaborated here one by one. Description of the Drawings

[0047] Embodiment 1:

[0048] Figure 1 It is a schematic structural diagram of the box cover of the electric control box provided in Embodiment 1 of the present utility model in a separated state; Figure 2 It is a schematic structural diagram of the electric control board in the electric control box provided in Embodiment 1 of the present utility model;

[0049] Figure 3 It is a three - dimensional cross - sectional view with a horizontal plane of the electric control box provided in Embodiment 1 of the present utility model; As Figures 1 - 3As shown in the figure, the electric control box provided in the first embodiment of the present utility model includes a box base 100 and a circuit board 200. The circuit board 200 is vertically installed on the box base 100. A plurality of wiring terminals are provided on the circuit board 200. The plurality of wiring terminals include a first wiring terminal 210 and a second wiring terminal 220. The wiring direction of the wire insertion port of the first wiring terminal 210 is the horizontal direction parallel to the circuit board 200, and the wiring direction of the wire insertion port of the second wiring terminal 220 is the vertical direction.

[0050] By arranging some of the wiring terminals to insert wires in the vertical direction and some of the wiring terminals to insert wires in the horizontal direction parallel to the circuit board 200, the number of wiring terminals that need to be arranged in each direction can be reduced, thereby reducing the size in each direction. This is conducive to reducing the height or width of the electric control box, facilitating the layout of the electric control box inside the wall-mounted air conditioner indoor unit, and is beneficial for the electric control box to be arranged in front of the wind turbine motor, thereby reducing the overall size of the wall-mounted air conditioner indoor unit.

[0051] Among them, in this embodiment, taking the electric control box located in the right half of the wall-mounted air conditioner indoor unit as an example, that is, the wind turbine motor is located at a position close to the right end on the base 410, the wind turbine (not shown in the figure) driven by the wind turbine motor is located on the left side of the wind turbine motor, and a motor gland 420 is provided outside the wind turbine motor. The cable connected to the wire insertion port of the first wiring terminal 210 is inserted into the wiring port of the first wiring terminal 210 from right to left, and the cable connected to the wire insertion port of the second wiring terminal 220 is inserted from bottom to top.

[0052] Among them, in this embodiment, the number of the first wiring terminals 210 is two, which are arranged vertically at the right end of the rear surface of the circuit board 200, and the number of the second wiring terminals 220 is two, which are arranged horizontally at the lower end of the rear surface of the circuit board 200.

[0053] Figure 4 The cross-section of the electric control box provided in the first embodiment of the present utility model is a three-dimensional cross-sectional view with a vertical plane; as Figure 4 shown, optionally, a first slot 110 is provided on the bottom wall of the box base 100, and the bottom of the circuit board 200 is inserted into the first slot 110.

[0054] By providing the first slot 110 on the bottom wall of the box base 100, it is beneficial to position the bottom of the circuit board 200 to improve the installation stability of the circuit board 200. Moreover, by using the insertion method to install the circuit board 200, compared with directly installing through a male threaded connector, the installation efficiency can be improved, and the local extrusion of the circuit board 200 can be reduced.

[0055] Among them, in this embodiment, the first slot 110 is provided on the upper surface of the bottom wall, and the first slot 110 has a slot bottom and extends in the left - right direction. Correspondingly, the circuit board 200 can be inserted into the first slot 110 in the direction from right to left.

[0056] Figure 5 is the three - dimensional exploded view of the electric control box provided by the first embodiment of the present utility model; as Figures 4 - 6 shown, optionally, the top wall of the box base 100 is provided with a second slot 120, the second slot 120 is parallel to the first slot 110, and the top of the circuit board 200 is inserted into the second slot 120.

[0057] By providing the second slot 120 on the top wall of the box base 100, it is beneficial to cooperate with the first slot 110 on the bottom wall of the circuit board 200 to position both the upper and lower edges of the circuit board 200, so that the circuit board 200 can maintain its position in the front - back direction and pitch, thereby improving the installation stiffness of the circuit board 200.

[0058] Among them, in this embodiment, the second slot 120 is provided on the lower surface of the top wall, and the second slot 120 has a slot bottom, that is, the position of the slot bottom is higher than the slot opening. The second slot 120 extends in the left - right direction. Correspondingly, the circuit board 200 can be inserted into the second slot 120 in the direction from right to left.

[0059] Specifically, in this embodiment, the slot wall of the second slot 120 has a guiding portion 121. In this embodiment, the guiding portion 121 is located at the right end of the second slot 120, that is, the end of the second slot 120 close to the box cover 300. Along the direction in which the circuit board 200 is inserted into the second slot 120, that is, from right to left, the distance between the side walls of the guiding portion 121 gradually decreases. More specifically, one side wall of the guiding portion 121 can be collinear with the side wall of the second slot 120, and the other side wall of the guiding portion 121 can extend obliquely with respect to the side wall of the guiding portion 121. For example, in this embodiment, along the insertion direction of the circuit board 200, it can be that the rear side wall of the guiding portion 121 extends left - frontward.

[0060] Figure 7 is the external view schematic diagram of the electric control box provided by the first embodiment of the present utility model; Figure 8 is the cross - sectional view of the electric control box provided by the first embodiment of the present utility model with the cross - section being a horizontal plane; Figure 9 is the three - dimensional cross - sectional view of the electric control box provided by the first embodiment of the present utility model with the cross - section being a horizontal plane at another position; as Figures 5 - 9 shown, optionally, the electric control box includes a box cover 300, the box cover 300 is buckled and fixedly connected to the box base 100 in the horizontal direction, and a positioning post 310 is further provided on the inner surface of the side wall of the box cover 300, and the positioning post 310 abuts against the side edge of the circuit board 200.

[0061] By making the lid 300 snap onto the base 100 in the horizontal direction and fixedly connected thereto, the positioning posts 310 provided on the lid 300 can be used to abut against the side edge of the circuit board 200, so as to apply a force to the side edge of the circuit board 200 in the horizontal direction, and cooperate with the first slot 110 or the first slot 110 and the second slot 120 to fix the circuit board 200, prevent the circuit board 200 from sliding left and right in the electric control box, and avoid the abnormal noise caused by the movement and collision of the circuit board 200 in the electric control box and the damage of the electronic components on the circuit board 200.

[0062] Specifically, in this embodiment, the lid 300 snaps onto the base 100 from right to left, while the illustrated direction in Figure 5 and Figure 6 is from left to right. Therefore, the positioning posts 310 abut against the right side edge of the circuit board 200 from right to left. Specifically, a threaded hole 140 is provided in the rear area at the lower right end of the base 100, and a through hole is provided at the corresponding position on the base 100 to pass through a male threaded connecting member such as a screw or a bolt, usually a screw, to fixedly connect the lid 300 and the base 100, and make the positioning posts 310 generate pressure to abut against the right side edge of the circuit board 200.

[0063] In this embodiment, the positioning post 310 includes a hollow column 313 and support rib plates 314 arranged along the outer peripheral surface of the hollow column 313. The cross section of the air column can be a hollow rectangle, and support rib plates 314 are provided on each side of the hollow rectangle. The support rib plates 314 are perpendicular to the side wall plate of the hollow rectangle. The reason for selecting the hollow column 313 is that on the one hand, it can reduce the weight and material usage of the lid 300, and on the other hand, it can also make the material thickness of each part of the lid 300 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 flatter and smoother. Of course, in another implementation manner, the hollow column 313 can also be circular.

[0064] As Figure 5 shown, optionally, the positioning post 310 includes an upper positioning post 311 and a lower positioning post 312. The upper positioning post 311 abuts against the upper part of the side edge of the circuit board 200, and the lower positioning post 312 abuts against the lower part of the side edge of the circuit board 200.

[0065] By providing the upper positioning post 311 to abut against the upper part of the side edge of the circuit board 200 and providing the lower positioning post 312 to abut against the lower part of the side edge of the circuit board 200, the upper and lower parts of the side edge of the circuit board 200 can be respectively abutted, and the abutting positions can be closer to the first slot 110 and the second slot 120, so as to jointly fix the upper and lower parts of the circuit board 200 by using the frictional force of abutting against the side edge of the circuit board 200 and the front and rear limiting effects of the first slot 110 and the second slot 120.

[0066] Among them, in this embodiment, the middle parts of the upper positioning post 311 and the lower positioning post 312 in the front-back direction can be in contact with the side edge of the circuit board 200.

[0067] Of course, in another implementation manner, only one positioning post 310 can be provided, and the positioning post 310 is in contact with the middle area of the side edge of the circuit board 200 in the height direction.

[0068] Figure 10 FIG. is a three-dimensional sectional view of the vertical plane at another position of the cross-section of the electric control box provided in the first embodiment of the present invention; as Figure 1 and Figure 10 shown, optionally, a first notch 130 is provided on the bottom wall of the box base 100, the first notch 130 is correspondingly arranged with the second wiring terminal 220, and the bottom wall of the box cover 300 shields a part of the first notch 130.

[0069] By providing the first notch 130 on the bottom wall of the box base 100 to correspond to the second wiring terminal 220, and using the bottom wall of the box cover 300 to shield a part of the first notch 130, the cable inserted into the second wiring terminal 220 is constrained and led out from the lower part of the electric control box, without occupying the horizontal side space of the electric control box, which is beneficial to the layout of the electric control box in a narrow space.

[0070] In this embodiment, the first notch 130 is provided at the right edge of the bottom wall of the box base 100, and the first notch 130 opens to the right. The first notch 130 is a first notch 130 that penetrates up and down, and the bottom wall of the box cover 300 of the electric control box shields a part of the first notch 130, which means that from the perspective of looking up, the bottom wall of the box cover 300 covers the right part of the first notch 130.

[0071] As Figure 1 and Figure 10 shown, optionally, a first wire blocking hook 131 is provided on the box base 100, and the first wire blocking hook 131 is lower than the first notch 130.

[0072] By providing the first wire blocking hook 131, the cable led out from the first notch 130 can be constrained, preventing the cable from being scattered or having too large a movement range, improving the service life of the cable, and also can constrain the cable before and during the buckling of the box cover 300, avoiding being clamped between the end face of the box base 100 and the box cover 300 to interfere with the buckling of the box cover 300.

[0073] Specifically, the first wire retaining hook 131 is disposed on the wire retaining hook plate 132, and the wire retaining hook plate 132 extends downward from the bottom wall of the box base 100 in the vertical direction. More specifically, the first wire retaining hook 131 is disposed at the bottom of the wire retaining hook plate 132. Starting from the root, the first wire retaining hook 131 first extends backward and then extends leftward, thereby forming an opening area with a backward opening to prevent the corresponding part of the cable from moving too far to the right.

[0074] As Figure 10 shown, optionally, the upper surface of the bottom wall of the box cover 300 is lower than the lower surface of the bottom wall of the box base 100.

[0075] By setting the upper surface of the bottom wall of the box cover 300 to be lower than the lower surface of the bottom wall of the box base 100, a space is formed between the bottom wall of the box cover 300 and the bottom wall of the box base 100, through which the cable led out from the wire insertion port of the first wiring terminal 210 can be led out backward. On the one hand, the length of this part of the cable can be reduced, saving cable materials. On the other hand, these cables do not need to be hooked by the first wire retaining hook 131, reducing the bending degree of the cables, which is beneficial to improving the service life of the cables.

[0076] The bottom wall of the box cover 300 can be provided with a second notch 320. The second notch 320 is rectangular, and the side edges of the second notch 320 are two adjacent edges of the rectangle. One side edge of the second notch 320 abuts against the plate surface of the wire retaining hook plate 132, and the other side edge abuts against the edge of the wire retaining hook plate 132. In other words, the wire retaining hook plate 132 can form a positioning relationship with the second notch 320.

[0077] As Figure 1 、 Figure 7 and Figure 10 shown, optionally, a second wire retaining hook 150 is further provided on the box base 100. The second wire retaining hook 150 is higher than the bottom wall of the box cover 300 and lower than the bottom wall of the box base 100.

[0078] By setting the second wire retaining hook 150 to be higher than the bottom wall of the box cover 300 and lower than the bottom wall of the box base 100, the cable led out from the first wiring terminal 210 can be hooked, preventing it from moving horizontally between the side end face of the box base 100 and the box cover 300 and interfering with the box cover 300 being fastened to the box base 100, thereby improving the installation efficiency.

[0079] Specifically, in this embodiment, most of the second wire hook 150 extends in the horizontal direction. Under the condition that the lid 300 is located on the right side of the base 100 in this embodiment, the second wire hook 150 first extends downward from its root, then extends forward, and then extends left-forward. The second wire hook 150 can restrain the cables led out from the first terminal 210 on the left side of the second wire hook 150, preventing these cables from moving to the right side of the right end face of the base 100 and interfering with the assembly operation of the lid 300 being buckled onto the base 100 from right to left.

[0080] Embodiment 2:

[0081] Figure 11 FIG. is a schematic structural diagram of a wall-mounted air conditioner indoor unit in the air conditioner provided in Embodiment 2 of the present utility model; Figure 12 FIG. is a schematic structural diagram of a wall-mounted air conditioner indoor unit in the air conditioner provided in Embodiment 2 of the present utility model in a state where the electric control box is separated. As Figure 11 and Figure 12 shown, Embodiment 2 also provides an air conditioner, including a wall-mounted air conditioner indoor unit, the wall-mounted air conditioner indoor unit including a base 410, a wind wheel motor, and the electric control box of any one of the above. The wind wheel motor is installed on the base 410, and the electric control box is located in front of the wind wheel motor.

[0082] By providing the above electric control box in the air conditioner, correspondingly, the air conditioner has all the advantages of the above electric control box, which will not be elaborated one by one here.

[0083] As Figure 11 and Figure 12 shown, in this embodiment, taking the electric control box located in the right half of the wall-mounted air conditioner indoor unit as an example, that is, the wind wheel motor is located at a position close to the right end on the base 410, and the wind wheel driven by the wind wheel motor is located on the left side of the wind wheel motor. Therefore, the space available for the layout of the electric control box and the cables connected thereto is relatively small. In this embodiment, by orienting the first terminal 210 and the second terminal 220 in different directions, the dimensions in each direction can be reduced, so as to facilitate the electric control box to adapt to a smaller space.

[0084] Although the present utility model is disclosed as above, the present utility model 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 utility model. Therefore, the protection scope of the present utility model should be subject to the scope defined by the claims.
