TECHNICAL FIELD

[0001] The utility model relates to air conditioner technical field, specifically, relate to a kind of air conditioner wall-mounted machine middle frame and air conditioner. BACKGROUND

[0002] In prior art, the filter screen of wall-mounted air conditioner indoor unit, in order to increase its filter area, recessed portion is arranged in the front of filter screen, so as to make full use of the space above the front folding portion of indoor heat exchanger. The air conditioner wall-mounted machine middle frame of air conditioner is usually supported by support beam at the top thereof, so as to support the top of air conditioner wall-mounted machine middle frame, and further support the air conditioner wall-mounted machine middle frame. When the filter screen with increased filter area is installed on the air conditioner wall-mounted machine middle frame, support plates are arranged on the filter screen at positions opposite to the support beams, and the support plates are respectively arranged on the left and right sides of each support beam, so as to avoid the support beams, and the filter screen is arranged between the opposite support plates. If there are three support beams, six support plates are arranged on the left and right sides of the three support beams, and in addition to the support plates at the left and right ends of the filter screen, there are totally eight support plates. The filter screen is arranged in four areas corresponding to the support plates.

[0003] With the above structure, the following problems may occur. First, the support plates have thickness, and the thickness of the support plates reduces the size of the filter screen in the left-right direction. In addition, from the perspective of manufacturing, the support plates cannot be completely vertical, and are slightly inclined relative to the vertical plane. Generally, the interval between the upper portions of the adjacent support plates on the left and right sides of each support beam is smaller than the width of the support beam, and the interval between the adjacent support plates is also reduced, which further compresses the size of the filter screen in the left-right direction. Therefore, although the recess of the filter screen can increase the area of the filter screen, the width of the filter screen cannot be fully utilized, and the filtering effect is affected.

[0004] Second, since the support beams are arranged on the front panel of the air conditioner wall-mounted machine middle frame to support the air conditioner wall-mounted machine middle frame, the middle and lower portions of the front panel of the air conditioner wall-mounted machine middle frame are not directly supported. If the wall-mounted air conditioner indoor unit is placed horizontally and is stepped on, the front panel of the air conditioner wall-mounted machine middle frame is deformed greatly, and the front panel of the air conditioner wall-mounted machine middle frame is easily damaged. In addition, the front panel of the air conditioner wall-mounted machine middle frame may contact the fins, which may damage the fins. SUMMARY

In addition, the inner side and the outer side are defined based on the components in the shape of a cavity, a box or a cylinder, the side of the cavity, the box or the cylinder facing the inner space thereof is the inner side, and the outer side is the side of the cavity or the box facing the outer space thereof.

[0042] Embodiment one:

[0043] Figure 1 The structure diagram of the middle frame of the wall-mounted air conditioner provided by the embodiment one of the present application; Figure 2 The installation process diagram of the middle frame of the wall-mounted air conditioner provided by the embodiment one of the present application; Figure 3 The top view of the middle frame of the wall-mounted air conditioner provided by the embodiment one of the present application. As shown in the figure, Figures 1-3 The middle frame 100 of the wall-mounted air conditioner provided by the embodiment one of the present application comprises a front panel 110 and a support beam 120. The rear side of the front panel 110 is connected with the support beam 120, and the support beam 120 is located at the upper part of the middle frame 100 of the wall-mounted air conditioner. The front part of the support beam 120 is provided with a lower recessed part.

[0044] The recessed space formed by the lower recessed part can accommodate the filter screen assembly 200 which is also provided with a lower recessed front part. Since the support beam 120 does not need to be avoided, the filter screen assembly 200 only needs to be provided with the spaced support strips 202 at the positions corresponding to the support beam 120. The width of the support strips 202 can be smaller than the width of the support beam 120, and the width of the filter screen assembly 200 in which the filter screen body 201 is not arranged in the left-right direction can be significantly reduced. Accordingly, the area of the filter screen body 201 of the filter screen assembly 200 can be increased, the filtering capacity can be improved, or the filter screen dust accumulation speed can be reduced under the condition of the same air volume and the same air quality. In addition, during the manufacturing process of the filter screen assembly 200, only one whole filter screen body 201 needs to be laid before injection molding, and multiple notches need not to be cut for avoiding the support beam 120, thereby shortening the operation time, improving the operation efficiency and reducing the production cost.

[0045] As shown in the figure, Figure 3As shown in the figure, in this embodiment, three support beams 120 can be provided, and the three support beams 120 are arranged along the left-right direction, one of the three support beams 120 is located at the middle of the air inlet on the top of the air conditioner wall-mounted machine middle frame 100 in the left-right direction, and the other two support beams 120 can be arranged radially symmetrically along the center of the support beam 120. More specifically, the shapes, sizes, and positions of the upper surfaces of the lower concave parts of the three support beams 120 are the same.

[0046] As shown in the figure, the upper surface of the lower concave part of the support beam 120 is arranged correspondingly with the lower surface of the lower concave area of the front part of the filter screen assembly 200, wherein the corresponding arrangement means that the heights of the two lower concaves are matched, and the positions of the two lower concaves are matched, and the lower concave space formed by the lower concave part can completely accommodate the lower concave area of the filter screen assembly 200.

[0047] As shown in the figure, Figure 4 Optionally, the support beam 120 includes a first support beam 130, and the first support beam 130 includes a first support rib plate 131, the first support rib plate 131 is located below the lower concave part, and the first support rib plate 131 extends to the lower part of the rear side of the front panel 110.

[0048] By arranging the first support rib plate 131 on the first support beam 130 and extending the first support rib plate 131 to the lower part of the rear side of the front panel 110, the first support rib plate 131 can be used to support the lower part of the front panel 110. Moreover, since the front part of the first support beam 130 is provided with a lower concave part, the first support rib plate 131 below the lower concave part can be used to support the first part adjacent to the front panel 110 in the middle of the height direction of the front panel 110, so that the distance between the upper end and the lower end of the front panel 110 from the bottom of the lower concave part is not large, which helps to improve the rigidity of the front panel 110.

[0049] As shown in the figure, Figure 4 The support beam 120 supports the upper part of the rear surface of the front panel 110, and when the front panel 110 is stepped on, the deformation amount of the middle and lower parts of the front panel 110 is relatively large. Directly using the first support beam 130 to support the middle part of the front panel 110 and using the first support rib plate 131 to extend to the lower part of the rear side of the front panel 110 can form a rib support structure in the lower part of the rear surface of the front surface, and the top of the rear side of the front panel 110 is also provided with a structure for the filter screen assembly 200 to lap, so that the top of the rear side of the front panel 110 can also be supported, and the rigidity of the top is improved. Thus, the rear side of the front panel 110 can be strengthened at different height positions, and the deformation thereof when being pressed can be reduced.

[0050] As shown in the figure, Figure 3 Optionally, the first support rib plate 131 is connected to the middle part of the rear side of the front panel 110 in the left-right direction.

[0051] Since both ends of the front panel 110 are supported by the side plates 150, the middle part of the front panel 110 is less rigid than both ends of the front panel 110 in the left-right direction, and the first support rib plate 131 is arranged in the middle part of the front panel 110 in the left-right direction, so that the middle part of the front panel 110 can be supported by the first support rib plate 131, and if the middle part of the front panel 110 in the left-right direction is pressed, the load can be borne by the first support beam 130, thereby reducing the deformation of the middle part of the front panel 110 in the left-right direction.

[0052] Figure 5 A schematic view of an air conditioner wall-mounted machine middle frame in the prior art applied to a wall-mounted air conditioner indoor unit; Figure 6 A structural schematic view of a wall-mounted air conditioner indoor unit to which the air conditioner wall-mounted machine middle frame provided in Embodiment One of the present application is applied and placed in a packaging box; as Figure 6 shown, especially after the air conditioner is packed, when stored in the packaging box, in the packaging box, most of the time, the two ends of the wall-mounted air conditioner indoor unit are supported by packaging materials such as foamed plastic, and the middle part of the wall-mounted air conditioner indoor unit is not supported. Therefore, as Figure 5 shown, the air conditioner wall-mounted machine middle frame in the prior art is only supported by the support beam 120 at the top, and if the packaging box is stepped on in the middle part in the length direction, the middle part of the front panel 110 in the left-right direction will be subjected to a relatively large pressure and a relatively large deformation, and the middle part of the front panel 110 will be collapsed. The first support rib plate 131 is extended to the lower part of the rear side of the front panel 110, so that the middle part of the front panel 110 in the left-right direction is supported in the whole height, and the collapse of the middle part of the air conditioner wall-mounted machine middle frame 100 is reduced.

[0053] Figure 7 A perspective sectional view of the wall-mounted air conditioner indoor unit to which the air conditioner wall-mounted machine middle frame provided in Embodiment One of the present application is applied; Figure 8 Another direction observation perspective sectional view of the wall-mounted air conditioner indoor unit to which the air conditioner wall-mounted machine middle frame provided in Embodiment One of the present application is applied; Figure 9 A sectional view of the wall-mounted air conditioner indoor unit to which the air conditioner wall-mounted machine middle frame provided in Embodiment One of the present application is applied. As Figures 7-9 shown, optionally, the support beam 120 comprises a second support beam 140, the second support beam 140 comprises a second support rib plate 141, the second support rib plate 141 is located below the lower recess, and the second support rib plate 141 is extended to the middle part of the rear side of the front panel 110 in the height direction.

[0054] Since the first support rib 131 of the first support beam 130 extends to the lower part of the rear side of the front panel 110, it is sufficient to support the lower part of the rear side of the front panel 110 at this position. Just because the lower part of the rear side of the front panel 110 at this position is supported, the deformation amount of the remaining position of the front panel 110 is also limited. By arranging the second support rib 141 of the second support beam 140 to extend to the middle part of the rear side of the front panel 110 in the height direction, the remaining position of the front panel 110 can be properly supported, the deformation of the front panel 110 supported by the second support beam 140 is reduced, and the material of the second support beam 140 is also reduced.

[0055] As shown in Figures 7-9 , optionally, the support beam 120 further comprises an upper support rib 132 and a lower support rib 133; the upper support rib 132 is connected to the first support rib 131 and the second support rib 141 respectively, and the upper support rib 132 forms the upper surface of the lower recess; the lower support rib 133 is connected to the first support rib 131 and the second support rib 141 respectively, and the lower support rib 133 forms the lower surface of the lower recess.

[0056] Since the support beam 120 is arranged in the area of the lower recess, the height of the lower recess changes obviously in the front-rear direction, so that the first support rib 131 and the second support rib 141 below the lower recess are subjected to force concentration. By arranging the upper support rib 132 and the lower support rib 133, the first support rib 131 and the second support rib 141 at the upper edge and the rear lower edge of the lower recess can be supported, the rigidity of this part of the area is improved, and the deformation amount of the lower recess is reduced.

[0057] Moreover, the upper support rib 132 arranged on the first support rib 131 and the second support rib 141 to form the upper surface of the lower recess can support the support strip 202 of the filter screen assembly 200.

[0060] The first support rib 134 and the second support rib 135 are both connected to the bottom of the upper support rib 132, and the first support rib 134 is located in front of the bottom of the upper support rib 132, and the second support rib 135 is located behind the bottom of the upper support rib 132.

[0061] As shown in Figures 7-9 Optionally, the first support rib 134 and the second support rib 135 are both arc-shaped and both upwardly open.

[0062] The first support rib 134 and the second support rib 135 are both arranged to be arc-shaped and upwardly open, so that the two ends of the first support rib 134 and the second support rib 135 are connected to the parts to which they are connected, and are as close to vertical as possible, so that the force can be directly transferred through the first support rib 134 and the second support rib 135, thereby preventing the connection between the first support rib 134 and the second support rib 135 and the corresponding part from breaking.

[0063] Specifically, in the embodiment, the first support rib 134 extends backward from the rear side of the front panel 110, then extends backward and upward, and intersects with the bottom of the upper support rib 132 at an angle as close to vertical as possible, and the upward angle of the first support rib 134 gradually increases from front to back. The second support rib 135 extends backward and downward from the bottom of the upper support rib 132, and the downward angle gradually decreases from front to back until it intersects with the lower support rib 133 at an angle close to vertical.
