Description

Technical Field

[0001] This application relates to, but is not limited to, the field of air conditioning equipment technology, specifically referring to an outdoor air conditioning unit and an air conditioner. Background Technology

[0002] For multi-split air conditioners, such as Figures 1 to 4 As shown, its outdoor air conditioning unit includes a chassis 10, a middle partition 20, a folded right front side panel 30 (the right front side panel 30 includes upper and lower parts, each part including a right side panel and a front panel), a folded right rear side panel 40 (the right rear side panel 40 includes a right side panel and a rear panel), a cover 50, a heat exchanger 70, and an electrical control box 60. During assembly: First, install the partition plate 20 and heat exchanger 70 on the chassis 10, with the rear end of the partition plate 20 fixedly connected to the first side plate 71 on the right side of the heat exchanger 70 by screws; then install the electrical control box 60 on the upper right side of the partition plate 20; then install the right rear side plate 40 on the right rear side of the partition plate 20, with the left end of the rear plate of the right rear side plate 40 fixedly connected to the first side plate 71 by screws, the lower end of the right rear side plate 40 located on the outer side of the side of the chassis 10 and fixedly connected to the side of the chassis 10 by screws, and the lower end of the right rear side plate 40 also has an insert 41 that is snapped downwards onto the side of the chassis 10; then install the right front side plate 30 on the right front side of the partition plate 20, and the right front side plate 30... The left end of the front panel of the chassis 10 is fixedly connected to the front end of the middle partition 20 by screws. The rear end of the right side panel of the right front panel 30 rests on the front end of the right side panel of the right rear panel 40 and is fixedly connected to the front end of the right side panel of the right rear panel 40 by screws. The lower end of the right front panel 30 is located on the outer side of the side of the chassis 10 and is fixedly connected to the side of the chassis 10 by screws. The lower rear end of the right side panel of the right front panel 30 is also hooked downward to the lower front end of the right side panel of the right rear panel 40 by hooks 31. Then the cover 50 is installed, and the upper ends of the right front panel 30 and the upper ends of the right rear panel 40 are both attached to the inner side of the side of the cover 50 and fixedly connected to the side of the cover 50 by screws.

[0003] When inspecting the electrical control box 60, the insert 41 at the lower end of the right rear side panel 40 is stuck downwards on the upper part of the side of the chassis 10, and the upper end of the right rear side panel 40 is located inside the side of the cover 50. Therefore, the cover 50 needs to be removed first. After removing the cover 50, the lower rear end of the right side panel of the right front side panel 30 is hooked downwards to the lower front end of the right side panel of the right rear side panel 40 via a hook 31. Thus, the right rear side panel 40 cannot be disassembled without removing the right front side panel 30. Therefore, the right front side panel 30 also needs to be removed before the right rear side panel 40 can be disassembled. After removing the right rear side panel 40, the electrical control box 60 can be inspected. This solution is not only complicated in operation, but also difficult to disassemble and assemble due to the large height of the right rear side panel 40 and the limited distance between the right side panel of the right rear side panel 40 and the wall.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features described in this application can be arbitrarily combined with each other.

[0028] The air conditioner outdoor unit provided in this application embodiment, such as Figures 5 to 9As shown, it includes: a main body 100, which has a heat exchange chamber 110 and an installation chamber 120. The installation chamber 120 has an opening (which is a folded structure) on its rear side, including an upper opening portion 121 and a lower opening portion 122; an electrical control box 200, which is located on the upper part of the installation chamber 120 and is correspondingly arranged with respect to the upper opening portion 121; a folded lower rear plate 300 (including a side plate located on the front side and erected in the front-rear direction and a rear plate located on the rear side and erected in the left-right direction), which covers the lower opening portion 122; and a folded upper rear plate 400 (including a side plate located on the front side and erected in the front-rear direction and a rear plate located on the rear side and erected in the left-right direction), which covers the upper opening portion 121. The rear plate of the lower rear plate 300 is located between the side plate of the lower rear plate 300 and the heat exchange chamber 110, and the rear plate of the upper rear plate 400 is located between the side plate of the upper rear plate 400 and the heat exchange chamber 110.

[0029] The outdoor unit of this air conditioner has a separate upper rear panel 400 and lower rear panel 300. Only the upper rear panel 400 needs to be removed, without removing the lower rear panel 300, to inspect the electrical control box 200. Compared to the upper rear panel 400 and lower rear panel 300 which are connected as a single unit, this solution is simpler to operate. Moreover, because the upper rear panel 400 is small in height, it is easy to remove even if the distance between the side panel of the upper rear panel 400 and the wall is limited. Therefore, this solution is also easier to disassemble and assemble.

[0030] In some examples, such as Figures 5 to 9 As shown, the upper end of the lower rear plate 300 is provided with an overlapping portion (the overlapping portion is the first overlapping portion), and the lower end of the upper rear plate 400 is provided with an overlapping mating portion (the overlapping mating portion is the first overlapping mating portion). The first overlapping mating portion overlaps with the side of the first overlapping portion facing the outside of the mounting chamber 120 (see position a) to better achieve waterproofing. The first overlapping portion and the first overlapping mating portion are fixedly connected by a first screw 510, that is, the threaded end of the first screw 510 passes through the first overlapping mating portion and is screwed onto the first overlapping portion.

[0031] The number of first screws 510 may be one; or the number of first screws 510 may be multiple, such as two, three, or four. Both of these can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

[0032] In some examples, such as Figures 5 to 9As shown, the upper opening portion 121 has an overlapping portion (the overlapping portion is the second overlapping portion) on the wall of the heat exchange chamber 110 adjacent to the heat exchange chamber 110. The upper rear plate 400 has an overlapping mating portion (the overlapping mating portion is the second overlapping mating portion) at one end of the rear plate adjacent to the heat exchange chamber 110. The second overlapping mating portion overlaps the rear side of the second overlapping portion (see position b), and the second overlapping portion and the second overlapping mating portion are fixedly connected by a second screw 520, that is, the threaded end of the second screw 520 passes through the second overlapping mating portion and is screwed onto the second overlapping portion.

[0033] The number of second screws 520 may be one; or the number of second screws 520 may be multiple, such as two, three, or four. Both of these can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

[0034] In some examples, such as Figures 5 to 9 As shown, the front side wall of the upper opening portion 121 is provided with an overlapping portion (the overlapping portion is the third overlapping portion), and the front end of the side plate of the upper rear plate 400 is provided with an overlapping mating portion (the overlapping mating portion is the third overlapping mating portion). The third overlapping mating portion extends forward into the mounting chamber 120 and overlaps with the side of the third overlapping portion facing the interior of the mounting chamber 120 (see position c). The third overlapping portion and the third overlapping mating portion are fixedly connected by a third screw 530, that is, the threaded end of the third screw 530 passes through the third overlapping portion and is screwed onto the third overlapping mating portion.

[0035] The number of third screws 530 may be one; or the number of third screws 530 may be multiple, such as two, three, or four. Both of these can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

[0036] In some examples, such as Figures 5 to 9 As shown, the upper wall of the upper opening portion 121 is provided with an overlapping portion (the overlapping portion is the fourth overlapping portion), and the upper end of the upper rear plate 400 is provided with an overlapping mating portion (the overlapping mating portion is the fourth overlapping mating portion). The fourth overlapping mating portion extends upward into the mounting chamber 120 and overlaps with the side of the fourth overlapping portion facing the interior of the mounting chamber 120 (see position d). The fourth overlapping portion and the fourth overlapping mating portion are fixedly connected by a fourth screw 540, that is, the threaded end of the fourth screw 540 passes through the fourth overlapping portion and is screwed onto the fourth overlapping mating portion.

[0037] The number of fourth screws 540 can be one; or the number of fourth screws 540 can be multiple, such as two, three, or four. Both of these can achieve the purpose of this application, and their purpose has not deviated from the design concept of this utility model. They will not be elaborated here, and all should fall within the protection scope of this application.

[0038] This solution only requires removing the first screw 510, the second screw 520, the third screw 530 and the fourth screw 540 to remove the upper rear panel 400, so as to carry out maintenance on the electrical control box 200. The operation process is simpler and the disassembly and assembly are easier.

[0039] In some embodiments, such as Figures 7 to 9 As shown, the first overlapping part, the second overlapping part, the third overlapping part, the fourth overlapping part, the first overlapping mating part, the second overlapping mating part, the third overlapping mating part, and the fourth overlapping mating part are all overlapping edges. The overlapping edge structure is simple, easy to manufacture, and has a good sealing and waterproof effect.

[0040] In some embodiments, such as Figures 5 to 9 As shown, the main body 100 includes: a chassis 130; a central partition plate, which is erected on the chassis 130 along the front-rear direction; a heat exchanger 150, which is disposed on the chassis 130, and the rear end of the central partition plate is fixedly connected to the first side plate 151 of the heat exchanger 150; and a folded front side plate 160 (including a side plate located on the rear side and erected along the front-rear direction and a front plate located on the front side and erected along the left-right direction), which is disposed on the chassis 130, and the end of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the front plate of the central partition plate of the front ... The end is fixedly connected; and a cover 170, which covers the upper part of the side front plate 160, the middle partition plate, and the heat exchanger 150. The cover 170, the first side plate 151, the middle partition plate, the side front plate 160, and the chassis 130 together form an installation chamber 120. The heat exchange chamber 110 is located on the side of the middle partition plate facing away from the installation chamber 120. The fins of the heat exchanger 150 and the second side plate of the heat exchanger 150 are located in the heat exchange chamber 110. The cover 170, the first side plate 151, the side plate of the side front plate 160, and the chassis 130 together form an opening. The side front plate 160 is located in front of the upper rear plate 400 and the lower rear plate 300. The front plate of the side front plate 160 is located between the side plate of the side front plate 160 and the heat exchange chamber 110.

[0041] Among them, such as Figures 5 to 9As shown, the lower end of the upper rear plate 400 overlaps the upper end of the lower rear plate 300 on the side facing the outside of the mounting chamber 120 (i.e., the first overlapping part overlaps the side of the first overlapping part facing the outside of the mounting chamber 120). One end of the rear plate of the upper rear plate 400 adjacent to the heat exchange chamber 110 overlaps the upper part of the rear side of the first side plate 151 (the upper part of the first side plate 151 includes the second overlapping part) (i.e., the second overlapping part overlaps the rear side of the second overlapping part). One end of the rear plate of the lower rear plate 300 adjacent to the heat exchange chamber 110 overlaps the lower part of the rear side of the first side plate 151. The front end of the side plate of the upper rear plate 400 overlaps the rear end of the side plate of the side front plate 160 (the upper part of the rear end of the side plate of the side front plate 160 includes the second overlapping part). The upper part of the side facing the interior of the mounting chamber 120 (i.e., the third overlapping part extends forward into the mounting chamber 120 and overlaps with the side facing the interior of the mounting chamber 120 of the third overlapping part), the front end of the side plate of the lower rear plate 300 extends forward into the mounting chamber 120 and overlaps with the lower part of the side facing the interior of the mounting chamber 120 of the rear end of the side plate of the side front plate 160, the cover 170 has a side (the side of the cover 170 has a fourth overlapping part), the upper end of the upper rear plate 400 extends upward into the mounting chamber 120 and overlaps with the side facing the interior of the mounting chamber 120 of the side of the cover 170 (i.e., the fourth overlapping part overlaps with the side facing the interior of the mounting chamber 120 of the fourth overlapping part).

[0042] Alternatively, both the upper front plate 160 and the lower front plate 160 can be located on the right side of the partition plate, the heat exchange chamber 110 can be located on the left side of the mounting chamber 120, and the partition plate can be located between the heat exchange chamber 110 and the mounting chamber 120. In this configuration, the first overlapping part at the lower end of the upper rear plate 400 overlaps with the right side of the first overlapping part at the upper end of the lower rear plate 300. The second overlapping part at the left end of the rear plate of the upper rear plate 400 overlaps with the upper part of the rear side of the first side plate 151 (the upper part of the first side plate 151 forms the second overlapping part). The left end of the rear plate of the lower rear plate 300 overlaps with the lower part of the rear side of the first side plate 151. The front end of the side plate of the upper rear plate 400 extends forward into the mounting chamber 120 and overlaps with the upper part of the left side of the rear end of the side plate of the side front plate 160 (the side plate of the side front plate 160...). The upper part of the rear end forms a third overlapping part. The front end of the side plate of the lower rear plate 300 extends forward into the mounting chamber 120 and overlaps with the lower part of the left side of the rear end of the side plate of the side front plate 160. The cover 170 has an annular side (the annular side of the cover 170 has a fourth overlapping part formed on both the right and rear sides). The upper end of the side plate of the upper rear plate 400 and the upper end of the rear plate of the upper rear plate 400 both form a fourth overlapping mating part. The fourth overlapping mating part at the upper end of the side plate of the upper rear plate 400 extends upward into the mounting chamber 120 and overlaps with the left side of the fourth overlapping part on the right side of the side of the cover 170. The fourth overlapping mating part at the upper end of the rear plate of the upper rear plate 400 extends upward into the mounting chamber 120 and overlaps with the front side of the fourth overlapping part on the rear side of the side of the cover 170.

[0043] This solution allows for the removal of the upper rear panel 400 without removing the front side panel 160, cover 170, and lower rear side panel 300 (the upper rear side panel 400 can be removed by simply removing the first screw 510, the second screw 520, the third screw 530, and the fourth screw 540), thus enabling the maintenance of the electrical control box 200. The operation process is simpler and the disassembly and assembly are easier.

[0044] Among them, such as Figure 5 As shown, one end of the rear plate of the lower rear plate 300 adjacent to the heat exchange chamber 110 is fixedly connected to the first side plate 151 by the fifth screw 550, the front end of the side plate of the lower rear plate 300 is fixedly connected to the rear end of the side plate of the side front plate 160 by the sixth screw 560, and the lower end of the lower rear plate 300 is fixedly connected to the side of the chassis 130 by the seventh screw 570.

[0045] The air conditioner provided in this application embodiment (not shown in the figure) includes the air conditioner outdoor unit described in any of the above embodiments.

[0046] This air conditioner possesses all the advantages of the outdoor unit provided in any of the above embodiments, which will not be repeated here.

[0047] In summary, the technical solution provided in this application embodiment has a separate upper and lower rear panel structure. Only the upper rear panel needs to be removed, without removing the lower rear panel, to perform maintenance on the electrical control box. Compared to the upper and lower rear panels that are connected as a single unit, this solution is simpler to operate. Moreover, due to the small height of the upper rear panel, even if the distance between the side panel of the upper rear panel and the wall is limited, it is easy to remove the upper rear panel. Therefore, this solution is also less difficult to disassemble and assemble.
