[0028] With reference to Figures 1 to 8As shown, according to an embodiment of the present invention, a ceiling-mounted air conditioner is provided, which includes an air conditioner bottom plate 1 and an air conditioner cover plate 2 covering and connected to the air conditioner bottom plate 1. There is a frame 5 between the air conditioner bottom plate 1 and the air conditioner cover plate 2. An accommodation space is formed between the air conditioner cover plate 2, the air conditioner bottom plate 1 and the two side frames 5. A middle partition 6 is also provided in the accommodation space. The middle partition 6 is located in the accommodation space and is connected and supported between the air conditioner bottom plate 1 and the air conditioner cover plate 2. The middle partition 6 divides the accommodation space into two areas, an air inlet chamber and an air outlet chamber. A blower 72 is provided in the air inlet chamber, and a heat exchanger 74 is provided in the air outlet chamber. The blower 72 can drive the external air flow into the air inlet chamber and enter the air outlet chamber to exchange heat with the heat exchanger 74 and then discharge from the air conditioner. The air inlet chamber has an air inlet, and the air inlet includes a first air inlet 31 on one side of the air conditioner cover plate 2 and a second air inlet 32 on one side of the air conditioner bottom plate 1. In this technical solution, the first air inlet 31 on one side of the air conditioner cover plate 2 and the second air inlet 32 on one side of the air conditioner bottom plate 1 are set at the same time, so that the space on one side of the air conditioner bottom plate 1 can be fully utilized, and thus the air inlet area and air inlet volume of the air conditioner are effectively increased. It can be understood that in the prior art, based on the hoisting scenario of the ceiling-mounted air conditioner, an air inlet is not often provided on one side of the air conditioner bottom plate 1, while the present invention breaks through this inertial thinking in the prior art and also provides a corresponding air inlet on one side of the air conditioner bottom plate 1. Of course, when the ceiling-mounted air conditioner is hoisted, it is necessary to ensure the distance (for example, a net space distance of 30 mm should be maintained) between the second air inlet 32 and the hoisting carrier (such as a wall, a ceiling).

[0029] In some specific embodiments, the floor-suspended air conditioner further includes an air inlet grille 3, which is detachably connected to the air inlet. The first air inlet 31 and the second air inlet 32 are both formed on the air inlet grille 3. Constructing both the first air inlet 31 and the second air inlet 32 on the air inlet grille 3 can simplify the design of the air conditioner housing, and at the same time make the air inlet of the air conditioner more open during maintenance, facilitating maintenance. More specifically, the air inlet grille 3 includes a first frame, a second frame spaced apart and parallel to each other, and a third frame connected between the first frame and the second frame. The first air inlet 31 is formed on the first frame, the second air inlet 32 is formed on the second frame, and the first frame, the third frame, and the second frame are sequentially connected to form a U-shaped structure. The air inlet grille 3 can be formed by injection molding. The connection between the air inlet grille 3 and the air inlet of the air conditioner can be various. As a preferred embodiment, the first frame is rotatably connected to the air conditioner cover plate 2; and / or, the second frame is snap-connected (the preferred clearance of the fit is 2.0 mm) to the air conditioner bottom plate 1. In this way, the opening and closing of the air inlet grille 3 can be greatly facilitated, and further the maintenance (such as replacing and cleaning the filter screen provided therein) can be facilitated. Specifically, a corresponding rotating shaft is provided at the outer edge (i.e., the side away from the third frame) of the first frame, and a corresponding embedding groove (not marked in the figure) is opened at the corresponding outer edge of the air conditioner cover plate 2. The rotating shaft can be inserted into the rotating hole of the embedding groove, so that the air inlet grille 3 can pivot relative to the air conditioner cover plate 2. An elastic buckle is provided at the outer edge (i.e., the side away from the third frame) of the second frame, and a corresponding locking groove is provided at the corresponding outer edge of the air conditioner bottom plate 1. The elastic buckle can be snap-connected into the locking groove by relying on its own elasticity, thereby realizing the fixed connection of the air inlet grille 3. This structure does not require screw and bolt connection, greatly simplifying its assembly process.

[0030] Further, the floor-suspended air conditioner further includes a third air inlet 33, which is formed on the third frame, that is, the air inlet grille 3 has a three-sided air inlet structure, further increasing the air inlet area of the air conditioner.

[0031] The pedestal-mounted air conditioner further includes side plates 41 which are connected to the outer sides of the frames 5, enhancing the aesthetic appearance of the air conditioner. It can be understood that there are two relatively arranged frames 5, and correspondingly, there are also two side plates 41. Preferably, the side plates 41 are configured with side air inlets 42 which communicate with the air inlet chamber, thereby further increasing the air inlet area of the air conditioner. At this time, the air inlet chamber forms a five-sided air inlet structure, maximizing the design of the air inlet area.

[0032] To adapt to the setting of the third air inlet 33, support feet 43 are provided on the side plates 41. The support feet 43 are arranged on the side of the side plates 41 facing the third air inlet 33, so that when the pedestal-mounted air conditioner is in the pedestal-mounted scenario, the third air inlet 33 has an air inlet space. In some specific cases, the support height of the support feet 43 should not be less than 30 mm.

[0033] The side plates 41 are detachably connected to the frames 5. In some embodiments, on the side of the side plates 41 facing the corresponding frames 5, there are side plate hooks 44, and on the frames 5, there are frame slots 51. The side plate hooks 44 are snap-connected to the frame slots 51, that is, the side plates 41 are connected to the frames 5 by snap connection, rather than using screws and bolts, which can improve the assembly efficiency of the air conditioner. Furthermore, the side plates 41 also have protruding portions 45, and positioning holes 46 are formed on the protruding portions 45. The edge of the air conditioner cover 2 has a positioning strip 21. The air conditioner cover 2 is pressed against the outside of the protruding portions 45 and the positioning strip 21 is inserted into the positioning holes 46. After the air conditioner cover 2 is installed, it can effectively position the adjacent side of the side plates 41, making the connection of the side plates 41 more reliable.

[0034] Preferably, at the position where the air conditioner cover 2 is connected to the middle partition 6, a groove 22 is formed which is recessed towards the middle partition 6. Through holes are provided on the bottom wall of the groove 22, so that the air conditioner cover 2 can be bolted through the bottom of the groove 22 and the middle partition 6. A decorative piece 23 is detachably connected in the groove 22. The decorative piece 23 can cover the bottom of the groove 22, thereby covering the connecting components of the two and further enhancing the aesthetic appearance of the air conditioner. The decorative piece 23 can be, for example, a decorative strip with preset characters, colors, patterns, etc. In terms of specific connection, one side of the decorative piece 23 is snap-connected to the groove wall of the groove 22; and / or, the decorative piece 23 is press-fitted into the groove 22.

[0035] A water receiving tray 71 is further provided in the air outlet cavity. The water receiving tray 71 is used to collect the condensed water that may be formed by the heat exchanger 74. The water receiving tray 71 is detachably connected to the air conditioner cover plate 2. The electrical box 73 of the air conditioner can be assembled with the frame 5 as a whole.

[0036] The following are the main assembly steps of the floor and ceiling-mounted air conditioner of the present invention:

[0037] First, snap the side plate 41 onto the corresponding frame 5 (on both sides) through the side plate hooks 44, and fit them in place. After assembling the air conditioner cover plate 2 and the water receiving tray 71 into a whole with screws, bolt-connect them to the middle partition plate 6 through the through holes at the bottom of the groove 22 to form a whole. At the same time, the positioning strips 21 on the two sides of the air conditioner cover plate 2 corresponding to the two side plates 41 are aligned with the positioning holes 46 on the protruding parts 45, and press down to achieve insertion. Then, bolt-connect the corresponding connection positions of the air conditioner cover plate 2, the air conditioner bottom plate 1, and the frame 5 reliably.

[0038] Second, install the decorative part 23. First, obliquely insert the side of the decorative part 23 with a male buckle into the jack on one side wall of the groove 22, and press the other side of the decorative part 23 to make it enter the groove 22, so as to achieve an interference fit between the decorative part 23 and the groove 22, covering the groove and the screws.

[0039] Finally, assemble the air inlet grille 3. Install the two connectors (rotating shaft, elastic buckle) of the air inlet grille 3. When it needs to be disassembled, just bend the symmetric buckles in the U-shaped groove on the air conditioner bottom plate 1 with your fingers towards the middle.

[0040] Specifically, when installed in a floor-mounted manner (i.e., in the floor-mounted scenario), the support of the support feet 43 ensures the smooth air inlet of the third air inlet 33 (the air inlet clearance is not less than 30 mm); in the hoisting scenario, enough space for disassembling and assembling the grille needs to be reserved. The distance between the air conditioner bottom plate 1 and the wall is not less than 50 mm, and the distance from the upper side to the wall is not less than 20 mm.

[0041] It is easy for those skilled in the art to understand that, on the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0042] The above is only the preferred embodiment of the present invention, and it is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present invention.
