Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and in particular, 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] In some existing wall-mounted air conditioner indoor units, the electric control box is arranged in front of the wind wheel motor, that is, on the side close to the main indoor space. However, with such an arrangement, the position of the electric control box is raised as a whole, which may interfere with the middle frame, especially the corner edge of the middle frame, and is not conducive to the layout of the electric control box. Summary of the Utility Model

[0004] The purpose of the first aspect of the utility model is to provide a wall-mounted air conditioner indoor unit to solve the technical problem that the chamfer of the existing middle frame affects the layout of the electric control box.

[0005] The wall-mounted air conditioner indoor unit provided by the first aspect of the utility model includes a base, a middle frame, a wind wheel motor and an electric control box. The upper edge of the end face of the first end of the middle frame has a first chamfer part. The wind wheel motor is installed on the base. The electric control box is located in front of the wind wheel motor and inside the first end of the middle frame. The upper edge of the end face of the first end of the electric control box is provided with a second chamfer part.

[0006] The beneficial effects brought by the wall-mounted air conditioner indoor unit provided by the first aspect of the utility model are as follows:

[0007] By setting the second chamfer part, the distance between the upper edge of the end face of the first end of the electric control box and the inner side face of the first chamfer part can be increased, preventing interference between the electric control box and the first chamfer part of the middle frame to ensure the smooth installation of the middle frame.

[0008] In an optional technical solution, the electric control box includes a box seat and a box cover. The box cover is buckled on the box seat in the direction away from the first end, and the upper part of the box cover is provided with the second chamfer part.

[0009] Setting the second chamfer part on the box cover instead of the box seat is beneficial for the circuit board to be arranged on the box seat. The electric control box is connected to the base through the box seat, and the circuit board and the electronic components and electrical components thereon are relatively heavy and can be borne by the box seat. Setting the second chamfer part on the box cover will not affect the force-bearing structure of the box seat, thus ensuring the rigidity of the electric control box.

[0010] In an alternative technical solution, the electronic control box further includes a circuit board. An inner wall surface of an upper portion of a side wall of the box cover is provided with a first positioning post, and the first positioning post abuts against a side edge of the circuit board.

[0011] By providing the first positioning post on the inner wall surface of the upper portion of the side wall of the box cover, the first positioning post can be used to abut against the side edge of the circuit board, which can directly prevent the upper portion of the circuit board from toppling towards the box cover. Moreover, since the first positioning post abuts against the side edge of the circuit board, there is a frictional force between the two, which can prevent the upper portion of the circuit board from toppling in the front-back direction.

[0012] In an alternative technical solution, the box cover is provided with a flanging portion, the flanging portion wraps at least a part of an edge of a first end of the box base, and an inner side surface of the flanging portion is provided with an anti-retreat portion, and the anti-retreat portion cooperates with an anti-retreat hole provided on the box base.

[0013] By providing the flanging portion to include at least a part of the edge of the first end of the box base, the overlapping area between the box cover and the box base can be increased, and the entry of dust can be reduced. Moreover, by providing the anti-retreat portion, after the box cover is fastened to the box base, it can be locked in the direction away from the box base, which can prevent the box cover from separating from the box base and improve the reliability of their connection.

[0014] In an alternative technical solution, the anti-retreat portion includes a wedge-shaped tongue provided on the flanging portion. The wedge-shaped tongue extends downward from an inner side surface of the flanging portion located at the top of the box cover, and the wedge-shaped tongue is inserted into the anti-retreat hole.

[0015] By providing the wedge-shaped tongue extending downward from the flanging portion at the top of the box cover, the box cover can be hooked by the wedge-shaped tongue. When the box cover is directly moved horizontally, the box cover cannot be separated from the box base, thereby improving the reliability of the connection between the box cover and the box base.

[0016] In an alternative technical solution, the box cover has a flanging portion, and a rear upper portion of the flanging portion has a third chamfering portion; a rear wall of the box base has a first wire outlet and a first wire pressing portion, the first wire pressing portion is located behind the first wire outlet, and the third chamfering portion wraps a part of the first wire pressing portion.

[0017] By providing the third chamfering portion to wrap the first wire pressing portion, auxiliary support can be formed for the first wire pressing portion, which is beneficial to improving the stiffness of the first wire pressing portion, so that the first wire pressing portion can more firmly press down the cable led out from the first wire outlet and prevent it from warping up and interfering with other components of the wall-mounted air conditioner indoor unit.

[0018] In an alternative technical solution, the flanging portion further includes a downward extending portion, and the downward extending portion extends downward from the third chamfering portion; the downward extending portion shields a part of the lower rear of the first wire outlet.

[0019] By arranging the lower extension part to block a part of the lower rear of the first wire outlet, a part of the opening space below the first wire pressing part can be blocked, so as to reduce the directly exposed area outside the first wire outlet, thereby reducing the speed of dust entering the inside of the electric control box and improving the service life of the electric control box.

[0020] In an alternative technical solution, the electric control box includes a circuit board; an inner side surface of the top wall of the box base is provided with a first slot, and an upper end of the circuit board is inserted into the first slot; the box cover has a flanging part, and a receiving part is provided at the top of the flanging part, and the receiving part receives the first end of the first slot.

[0021] By arranging the first slot for the top of the circuit board to be inserted, the front and back tipping of the top of the circuit board can be prevented. And by arranging a receiving part at the top of the flanging part to receive the first slot, the length of the first slot can be increased in the direction towards the first end, so that the first slot can communicate with the side wall of the first end of the box base, thereby facilitating the insertion of the top of the circuit board into the first slot.

[0022] In an alternative technical solution, a vertically penetrating notch part is provided at the top of the flanging part, and an opening direction of the notch part faces away from the first end, and the notch part receives the first end of the first slot.

[0023] By arranging the notch part to receive the first end of the first slot, the first slot can extend to the side edge of the first end of the box base, which is beneficial to increasing the length of the first slot and enabling the first slot to better guide the insertion process of the top of the circuit board. Moreover, by using the notch part to form the receiving part, the height of the top of the box cover can be reduced, which is beneficial to avoiding interference with the inner side surface of the first chamfer part of the middle frame.

[0024] An object of the second aspect of the present invention is to provide an air conditioner to solve the technical problem that the chamfer of the middle frame affects the layout of the electric control box.

[0025] The air conditioner provided in the second aspect of the present invention includes an outdoor unit and a wall-mounted air conditioner indoor unit, and the outdoor unit is connected to the wall-mounted air conditioner indoor unit through a refrigerant connecting pipe.

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

[0046] Embodiment 1:

[0047] Figure 1 is a schematic structural view of the wall - mounted air - conditioner indoor unit provided in Embodiment 1 of the present utility model; Figure 2 is a schematic structural view of the wall - mounted air - conditioner indoor unit observed from another direction provided in Embodiment 1 of the present utility model; Figure 3 is a schematic structural view of the electric control box in the wall - mounted air - conditioner indoor unit provided in Embodiment 1 of the present utility model. As Figures 1-3As shown in the figure, the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model includes a base 410, a middle frame (not shown in the figure), a wind wheel motor (not shown in the figure), and an electric control box. The upper edge of the end face at the first end of the middle frame has a first chamfering portion (not shown in the figure). The wind wheel motor is installed on the base 410, and the electric control box is located in front of the wind wheel motor and inside the first end of the middle frame. The upper edge of the end face at the first end of the electric control box is provided with a second chamfering portion 310.

[0048] By providing the second chamfering portion 310, the distance between the upper edge of the end face at the first end of the electric control box and the inner side face of the first chamfering portion can be increased, preventing interference between the electric control box and the first chamfering portion of the middle frame, so as to ensure the smooth installation of the middle frame.

[0049] In this embodiment, the wind wheel motor is installed at a position close to the right end of the base 410 to drive the wind wheel on its left side. The wind wheel motor is blocked by the motor gland, and the electric control box is located in front of the motor gland.

[0050] Specifically, in this embodiment, the first end face is one of the left and right end faces of the electric control box. More specifically, in this embodiment, the electric control box is also located at the right end of the wall-mounted air conditioner indoor unit. The first end of the electric control box is the right end of the electric control box, the end face at the first end of the electric control box is the right end face of the electric control box, and the second chamfering portion 310 is provided at the upper edge of the right end face of the electric control box. Similarly, the first end of each component is the right end of the component in this embodiment. And the direction away from the first end is the leftward direction.

[0051] In this embodiment, the first chamfering portion can be an arc chamfering portion to improve the aesthetics of the air conditioner appearance. And the second chamfering portion 310 of the electric control box can be a straight chamfering portion, that is, the surface where the second chamfering portion 310 is located is a plane. More specifically, the angle between the second chamfering portion 310 and the plumb plane is 5°, 10°, or 15°, as long as there is enough space left between the upper edge of the first end face of the electric control box and the inner side face of the second chamfering portion 310. Or, in another implementation, the second chamfering portion 310 can also be an arc chamfer.

[0052] As Figures 1-3 shown, optionally, the electric control box includes a box base 100 and a box cover 300. The box cover 300 is buckled on the box base 100 in the direction away from the first end, and the upper part of the box cover 300 is provided with the second chamfering portion 310.

[0053] Setting the second chamfering portion 310 on the box cover 300 instead of the box base 100 is beneficial for the circuit board 200 to be arranged on the box base 100. The electric control box is connected to the base 410 through the box base 100, and the circuit board 200 and the electronic components and electrical components thereon are relatively heavy, and the weight can be borne by the box base 100. Setting the second chamfering portion 310 on the box cover 300 will not affect the force structure of the box base 100, thus ensuring the rigidity of the electric control box.

[0054] Figure 4 This is a schematic structural diagram of the lid of the electronic control box in the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model; Figure 5 This is a schematic structural diagram of the lid of the electronic control box in the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model when observed from another direction; as Figures 4-5 As shown, optionally, a first positioning post 320 is provided on the inner wall surface of the upper part of the side wall of the lid 300, and the first positioning post 320 abuts against the side edge of the circuit board 200.

[0055] By providing the first positioning post 320 on the inner wall surface of the upper part of the side wall of the lid 300, the first positioning post 320 can be used to abut against the side edge of the circuit board 200, which can directly prevent the upper part of the circuit board 200 from tilting towards the lid 300. Moreover, since the first positioning post 320 abuts against the side edge of the circuit board 200, there is friction between the two, which can prevent the upper part of the circuit board 200 from tilting in the front-rear direction.

[0056] Among them, in this embodiment, the lid 300 is snapped onto the base 100 in the direction from right to left. Therefore, the first positioning post 320 abuts against the right side edge of the circuit board 200 from right to left. In this embodiment, a threaded hole is provided in the rear area of the lower part of the right end of 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 to make the first positioning post 320 generate pressure to abut against the right side edge of the circuit board 200.

[0057] In this embodiment, the first positioning post 320 belongs to a positioning post. The positioning post includes a hollow column and support rib plates arranged along the outer peripheral surface of the hollow column. The cross-section of the hollow column can be a hollow rectangle, and further, a hollow square. Support rib plates are provided on each side of the hollow rectangle, and the support rib plates are perpendicular to this side of the hollow rectangle. The reason for choosing a hollow column 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 smoother and flatter.

[0058] In addition, below the first positioning post 320, a second positioning post 330 is also provided, and the second positioning post 330 also belongs to a positioning post. The second positioning post 330 abuts against the lower part of the right side edge of the circuit board 200.

[0059] Figure 6 This is a three-dimensional disassembly diagram of the electronic control box in the wall-mounted air conditioner indoor unit provided in the first embodiment of the present utility model; as Figures 4-6As shown, optionally, the lid 300 is provided with a flanging portion 340 that wraps at least partially around the edge of the first end of the base 100. A retaining portion 350 is provided on the inner side surface of the flanging portion 340, and the retaining portion 350 cooperates with a retaining hole 110 provided on the base 100.

[0060] By providing the flanging portion 340 to wrap at least partially around the edge of the first end of the base 100, the overlapping area between the lid 300 and the base 100 can be increased, reducing the entry of dust. Moreover, by providing the retaining portion 350, after the lid 300 is fastened to the base 100, it can be locked in the direction away from the base 100, preventing the lid 300 from detaching from the base 100 and improving the reliability of their connection.

[0061] Specifically, in this embodiment, the flanging portion 340 is located at the upper side edge, front side edge, front part of the lower side edge, and upper middle part of the rear side edge of the lid 300. The retaining portion 350 is provided on the upper side edge of the lid 300 and cooperates with a threaded hole located at the lower part of the base 100, enabling the lid 300 and the base 100 to be fixed from two places, namely, above and below. Specifically, after the lid 300 is fastened to the base 100, if a force is directly applied to cause the lid 300 to move towards the first end, that is, directly pulling the lid 300 out to the right from the base 100, the upper part of the lid 300 cannot be separated from the base 100.

[0062] Figure 7 This is a three-dimensional disassembly view of the electronic control box in the wall-mounted air conditioner indoor unit provided by Embodiment 1 of the present utility model, observed from another direction; Figure 8 This is a three-dimensional disassembly view of the electronic control box in the wall-mounted air conditioner indoor unit provided by Embodiment 1 of the present utility model, observed from another direction; Figure 9 This is a structural schematic view of the electronic control box in the wall-mounted air conditioner indoor unit provided by Embodiment 1 of the present utility model, observed from another direction; As Figures 4-9 As shown, optionally, the retaining portion 350 includes a wedge-shaped tongue provided on the flanging portion 340. The wedge-shaped tongue extends downward from the inner side surface of the flanging portion 340 located at the top of the lid 300, and the wedge-shaped tongue is inserted into the retaining hole 110.

[0063] By providing the wedge-shaped tongue that extends downward from the flanging portion 340 at the top of the lid 300, the lid 300 can be hooked by the wedge-shaped tongue. When the lid 300 is directly moved horizontally, the lid 300 cannot be separated from the base 100, thereby improving the reliability of the connection between the lid 300 and the base 100.

[0064] Specifically, in this embodiment, the wedge-shaped tongue includes a wedge-shaped portion located below and a root portion located above, wherein the top end of the wedge-shaped portion has the same cross-section as the lower end of the root portion. The lower part of the wedge-shaped tongue is arranged in a wedge shape, which is beneficial to reducing the size of the bottom end of the wedge-shaped tongue, thereby facilitating the insertion of the wedge-shaped tongue into the anti-retreat hole 110. Specifically, the anti-retreat hole 110 in this embodiment penetrates the top wall of the box base 100 along the wall thickness direction. More specifically, in this embodiment, along the front-rear direction, two wedge-shaped tongues are arranged on the flanging portion 340 at the top of the box cover 300 to improve the fixing effect.

[0065] In another implementation, the anti-retreat portion 350 may include a fixed tongue, which extends leftward from the box cover 300. For example, it may be arranged on the upper part of the box cover 300. The fixed tongue also includes a wedge-shaped portion and a root portion. The thickness of the left end of the wedge-shaped portion is less than the thickness of its right end, and the thickness of the right end of the wedge-shaped portion is greater than the thickness of the root portion. The local part of the rear end face of the wedge-shaped portion hooks the anti-retreat hole 110.

[0066] As Figures 4-9 shown, optionally, the upper rear part of the flanging portion 340 has a third chamfered portion 360; the rear wall of the box base 100 has a first wire outlet 120 and a first wire pressing portion 130. The first wire pressing portion 130 is located behind the first wire outlet 120, and the third chamfered portion 360 wraps a part of the first wire pressing portion 130.

[0067] By providing the third chamfered portion 360 to wrap a part of the first wire pressing portion 130, auxiliary support can be formed for the first wire pressing portion 130, which is beneficial to improving the stiffness of the first wire pressing portion 130, so that the first wire pressing portion 130 can more firmly press down the wire led out from the first wire outlet 120 and prevent it from warping up and interfering with other components of the wall-mounted air conditioner indoor unit.

[0068] Specifically, the first wire pressing portion 130 includes a bent plate body, which extends downward and rearward from the rear wall of the box base 100 and then bends downward to form a plate body substantially along the vertical direction or a plate body substantially parallel to the rear wall of the box base 100. When the lead wire passes through the first wire outlet 120, it is pressed downward by the first wire pressing portion 130, so that the lead wire shows a state where the height is lower the farther away from the circuit board 200 in this area. The third chamfered portion 360 also has a state of being higher at the front and lower at the rear and cooperates with the rear surface of the inclined part of the first wire pressing portion 130 to improve the stiffness of the first wire pressing portion 130.

[0069] As Figures 4-9 shown, optionally, the flanging portion 340 further includes a lower extension portion 341, which extends downward from the third chamfered portion 360; the lower extension portion 341 blocks a part of the lower rear of the first wire outlet 120.

[0070] By setting the lower extension portion 341 to block a part of the lower rear of the first wire outlet 120, a part of the opening space below the first wire pressing portion 130 can be blocked, so as to reduce the directly exposed area outside the first wire outlet 120, thereby reducing the speed of dust entering the inside of the electric control box and improving the service life of the electric control box.

[0071] Specifically, in this embodiment, the lower extension portion 341 is arranged on the side of the lower end of the third chamfered portion 360 that biases towards the first end, that is, the side of the third chamfered portion 360 that biases towards the right end. Thus, the right half of the first wire outlet 120 can be blocked to reduce the exposed area at the right end of the first wire outlet 120. Moreover, since the right half of the rear wall of the box base 100 has a rearward protruding portion 150, the lower extension portion 341 can be attached to the protruding portion 150 to block the gap between the protruding portion 150 and the box cover 300.

[0072] As Figures 4-8 shown, optionally, the electric control box includes a circuit board 200; a first slot 140 is provided on the inner side of the top wall of the box base 100, and the upper end of the circuit board 200 is inserted into the first slot 140; a receiving portion 342 is provided at the top of the flanging portion 340, and the receiving portion 342 receives the first end of the first slot 140.

[0073] By setting the first slot 140 for the top of the circuit board 200 to be inserted, the front and back tipping of the top of the circuit board 200 can be prevented. And by setting the receiving portion 342 at the top of the flanging portion 340 to receive the first slot 140, the length of the first slot 140 can be increased in the direction towards the first end, so that the first slot 140 can communicate with the side wall of the first end of the box base 100, thereby facilitating the insertion of the top of the circuit board 200 into the first slot 140.

[0074] Certainly, at the bottom of the box base 100, a second slot (not shown in the figure) is also provided to receive the top of the circuit board 200. Through the cooperation of the first slot 140 and the second slot, the top and bottom of the circuit board 200 can be respectively limited to prevent the circuit board 200 from tipping forward and backward.

[0075] Figure 10 It is a schematic structural diagram of another implementation manner of the electric control box in the wall-mounted air conditioner indoor unit provided by the first embodiment of the present utility model; Figure 11 It is a schematic structural diagram of another implementation manner of the electric control box in the wall-mounted air conditioner indoor unit provided by the first embodiment of the present utility model when observed from another direction; except for the notch portion 343 that penetrates up and down mentioned later, as Figure 10 and Figure 11 shown, the receiving portion 342 can also be a hollow convex portion that protrudes upward, and the space inside the convex portion can receive the bottom and the side wall of the first slot 140.

[0076] AsFigures 4-9 As shown, optionally, a notch 343 penetrating vertically is provided at the top of the flanging portion 340, and the opening direction of the notch 343 faces away from the first end, and the first end of the first slot 140 is received in the notch 343.

[0077] By providing the notch 343 to receive the first end of the first slot 140, the first slot 140 can extend to the side edge of the first end of the box base 100, which is beneficial to increasing the length of the first slot 140, so that the first slot 140 can better guide the insertion process at the top of the circuit board 200. Moreover, by using the notch 343 to form the receiving portion 342, the height of the top of the box cover 300 can be reduced, which is beneficial to avoiding interference with the inner side surface of the first chamfered portion of the middle frame.

[0078] Wherein, in this embodiment, the notch 343 can be a rectangular notch, and the rectangular notch opens towards the left.
