[0046] like Figures 1 to 4 As shown in the figure, an air conditioner housing provided by this utility model embodiment includes a front panel 100, a top panel 200 and a rear panel 300. The front frame of the top panel 200 is connected to the upper side of the front panel 100, and the top panel 200 is provided with a first air inlet 210. The upper side of the rear panel 300 is connected to the rear frame 220 of the top panel 200, and the rear panel 300 is provided with an inclined plate 320. The inclined plate 320 gradually tilts from bottom to top towards the front panel 100, and the inclined plate 320 is provided with a second air inlet 310.

[0047] The air conditioner casing of this embodiment mainly consists of a front panel 100, a top panel 200, and a rear panel 300. The casing has panels in six directions: front, rear, left, right, top, and bottom. The front panel 100 faces forward, the rear panel 300 faces backward, and the top panel 200 faces upward. The front panel 100 faces the user, and the rear panel 300 faces the wall. The front edge of the top panel 200 is connected to the upper edge of the front panel 100, and the rear edge 220 of the top panel 200 is connected to the upper edge of the rear panel 300.

[0048] The top panel 200 is provided with a first air inlet 210 as the main air inlet. Airflow can enter the air conditioner casing through the first air inlet 210, and after heat exchange by the air conditioner heat exchanger 600, it is discharged from the air conditioner outlet 510. The rear panel 300 is provided with a second air inlet 310 as a secondary air inlet. Airflow can enter the air conditioner casing through the second air inlet 310, and after heat exchange by the air conditioner heat exchanger 600, it is discharged from the air conditioner outlet 510.

[0049] The second air inlet 310 is combined with the first air inlet 210 to increase the overall air intake area of ​​the air conditioner based on the first air inlet 210, thereby improving the heat exchange capacity of the heat exchanger 600. Moreover, the airflow enters the air conditioner from the rear of the casing through the second air inlet 310, which can make the air around the air conditioner be drawn in more evenly, reduce the situation of local airflow obstruction, improve the uniformity of return air, and help improve the uniformity of the overall indoor temperature.

[0050] The rear panel 300 has an inclined plate 320, and the second air inlet 310 is set on the inclined plate 320. The inclined plate 320 gradually tilts upwards towards the front panel 100, that is, the inclined plate 320 forms an air intake space 321 between the rear panel 300 and the wall through its tilt angle. When the air conditioner is mounted on the wall, it ensures that there is sufficient air intake space 321 between the wall and the inclined plate 320, ensuring smooth air intake of the second air inlet 310 and avoiding the problem of air intake obstruction of the second air inlet 310 caused by the rear panel 300 being tightly pressed against the wall due to the air conditioner mounting method. Moreover, the inclusion of the second air inlet 310 on the air conditioner casing can effectively reduce the weight of the casing and reduce component costs.

[0051] In this embodiment, both the first air inlet 210 and the second air inlet 310 can adopt the structure of an air inlet grille.

[0052] According to one embodiment of the present invention, the rear frame 220 is provided with a recessed portion 230, which is recessed from the rear panel 300 to the front panel 100 in a horizontal direction.

[0053] In this embodiment, the rear frame 220 of the top panel 200 is located above the rear panel 300. The rear frame 220 is provided with a recess 230. The recess 230 is formed by recessing from the rear panel 300 to the front panel 100 in the horizontal direction. Thus, the recess 230 forms a partition space 231 between the top panel 200 and the wall. The partition space 231 is connected to the air intake space 321 left between the inclined plate 320 and the wall. Therefore, the airflow behind and above the air conditioner can enter the air intake space 321 between the inclined plate 320 and the wall through the partition space 231, and then enter the second air intake 310 through the air intake space 321, further ensuring the smooth air intake of the second air intake 310.

[0054] According to one embodiment of the present invention, the recessed portion 230 is positioned corresponding to the second air inlet 310.

[0055] In this embodiment, the recessed portion 230 is located above and directly opposite the second air inlet 310. Based on the air inlet space 321 left between the inclined plate 320 and the wall through the partition space 231 between the top panel 200 and the wall, the partition space 231 is directly opposite the second air inlet 310, which shortens the distance from the partition space 231 to the second air inlet 310, making the air intake of the second air inlet 310 more concentrated and improving the air volume and wind force of the second air inlet 310.

[0056] According to one embodiment of the present invention, the inclined plate 320 is further provided with a third air inlet 330, which is located on both sides of the second air inlet 310 along the horizontal direction.

[0057] In this embodiment, a third air inlet 330 is also provided on the inclined plate 320 of the rear panel 300. The third air inlet 330 is located on both sides of the second air inlet 310. The rear panel 300, through the cooperation of the third air inlet 330 and the second air inlet 310, further increases the air intake area behind the air conditioner, allowing more airflow in the air intake space to enter the interior of the casing, thereby improving the heat exchange capacity of the heat exchanger 600 and the uniformity of the overall indoor temperature.

[0058] According to one embodiment of the present invention, the rear frame 220 is further provided with a hanging part 240, which is located on both sides of the recess 230.

[0059] In this embodiment, the rear frame 220 of the top panel 200 is also provided with a mounting part 240, which extends toward the wall, thereby mounting the air conditioner on the wall. The rear frame 220 is bent to form a recess 230, and the mounting part 240 is naturally constructed at both ends of the recess 230 by utilizing the curved configuration of the rear frame 220.

[0060] According to one embodiment of the present invention, the mounting part 240 is positioned between the second air inlet 310 and the third air inlet 330.

[0061] In this embodiment, the second air inlet 310 and the third air inlet 330 are spaced apart in the horizontal direction. The mounting part 240 is positioned to accommodate this space. Therefore, the arrangement of the third air inlet 330 and the second air inlet 310 allows space for the mounting part 240, ensuring the normal installation of the mounting part 240 and also ensuring that the air intake of the second air inlet 310 and the third air inlet 330 on the rear panel 300 is unobstructed.

[0062] According to one embodiment of the present invention, the air conditioner casing also includes a side panel 400, which is located on both sides of the rear panel 300 in the horizontal direction and connects the top panel 200, the front panel 100 and the rear panel 300 into one unit. The inner side of the side panel 400 is provided with a positioning protrusion 410, which extends from the front panel 100 through the top panel 200 to the rear panel 300.

[0063] In this embodiment, the outer shell mainly consists of a front panel 100, a top panel 200, a rear panel 300, and side panels 400. The outer shell has panels in six directions: front, rear, left, right, top, and bottom. The front panel 100 faces forward, the rear panel 300 faces backward, the top panel 200 faces upward, the left panel 400 faces left, and the right panel 400 faces right. The front panel 100 faces the user, and the rear panel 300 faces the wall. The front edge of the top panel 200 connects to the upper edge of the front panel 100, and the rear edge 220 of the top panel 200 connects to the upper edge of the rear panel 300. The edge of the left panel 400 connects to the left edges of the front panel 100, the top panel 200, and the rear panel 300, and the edge of the right panel 400 connects to the right edges of the front panel 100, the top panel 200, and the rear panel 300.

[0064] A positioning protrusion 410 is provided on the side panel 400 for installing the filter 700. The positioning protrusion 410 is located on the inner side of the side panel 400 facing the interior of the air conditioner and is continuously curved. The bending trend of the positioning protrusion 410 on the side panel 400 is from the front panel 100 to the top panel 200 and then to the rear panel 300. When installing the filter 700, first insert the filter 700 from the front panel 100, and then push the filter 700 into the housing and upwards. 00, the filter 700 moves along the positioning protrusion 410, bending from the rear of the front panel 100 to the bottom of the top panel 200. Continuing to push the filter 700, the filter 700 moves along the positioning protrusion 410, bending from the bottom of the top panel 200 to the front of the rear panel 300. The positioning protrusion 410 guides and positions the filter 700 during installation and ensures that the filter 700 covers the first air inlet 210 and the second air inlet 310, meeting the air intake filtration requirements of the air conditioner.

[0065] The air conditioner provided by this utility model is described below. The outer casing of the air conditioner described below can be referred to in correspondence with that of the air conditioner described above.

[0066] This utility model embodiment also provides an air conditioner, including the outer shell and heat exchanger 600 of the air conditioner as described in the above embodiment. The outer shell surrounds an inner cavity 500 and an air outlet 510. The first air inlet 210 and the second air inlet 310 are both connected to the air outlet 510 through the inner cavity 500. The heat exchanger 600 is disposed in the inner cavity 500.

[0067] The air conditioner of this utility model embodiment has an inner cavity 500 surrounded by six panels of the outer shell. A heat exchanger 600 is provided in the inner cavity 500. An air outlet 510 is formed between the bottom panel and the front panel 100. Air enters the inner cavity 500 through the first air inlet 210 and the second air inlet 310, undergoes heat exchange through the heat exchanger 600, and is then sent out through the air outlet 510.

[0068] According to one embodiment of the present invention, the air conditioner also includes a filter 700, and a positioning protrusion 410 is provided on the side panel 400 of the air conditioner housing, and the filter 700 is disposed on the positioning protrusion 410.

[0069] In this embodiment, since the second air inlet 310 on the rear panel 300 is close to the wall, there are relatively few dust and other impurities, and thus relatively little dust is drawn into the inner cavity 500. Moreover, the positioning protrusion 410 surrounds the outside of the heat exchanger 600, so that the filter screen 700 is entirely surrounded on the outside of the heat exchanger 600, and is also located below the first air inlet 210 and the second air inlet 310.

[0070] After air enters the inner cavity 500 through the first air inlet 210 and the second air inlet 310, it must pass through the filter screen 700 and then the heat exchanger 600 for heat exchange. This ensures that the air is fully filtered before passing through the heat exchanger 600, thereby filtering the air more effectively, extending the service life of the filter screen 700, and ensuring the air purification effect.

[0071] According to one embodiment of the present invention, the heat exchanger 600 includes a first evaporator 610, a second evaporator 620 and a third evaporator 630. The first evaporator 610 is disposed facing the front panel 100; the second evaporator 620 is disposed at an inclination between the front panel 100 and the top panel 200; the third evaporator 630 is disposed at an inclination between the top panel 200 and the rear panel 300, and the second air inlet 310 faces the third evaporator 630.

[0072] This implementation.

[0073] In the example, the heat exchanger 600 is a three-stage heat exchanger 600, mainly consisting of a first evaporator 610, a second evaporator 620, and a third evaporator 630. The first evaporator 610, the second evaporator 620, and the third evaporator 630 are arranged sequentially along the direction from the front panel 100 to the top panel 200 to the rear panel 300, thereby forming an effect of surrounding the fan in the inner cavity 500. The first evaporator 610 faces the front panel 100, the second evaporator 620 is inclined and faces the direction where the top panel 200 intersects with the front panel 100, and the third evaporator 630 is also inclined and faces the direction where the top panel 200 intersects with the rear panel 300.

[0074] The airflow from the first air inlet 210 of the top panel 200 can fully exchange heat through the second evaporator 620 and the first evaporator 610. The second air inlet 310 and the third air inlet 330 of the rear panel 300 are directly opposite the third evaporator 630, so the airflow from the second air inlet 310 and the third air inlet 330 can fully exchange heat through the third evaporator 630. Thus, by adding the second air inlet 310 and the third air inlet 330 to the rear panel 300, the air inlet area of ​​the corresponding third evaporator 630 is increased, thereby improving the heat exchange capacity of the third evaporator 630 and making full use of the three-stage heat exchanger 600.

[0075] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
