DETAILED DESCRIPTION

[0031] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] In the present invention, unless otherwise specified, the directional words used, such as "up" and "down", usually refer to the directions shown in the drawings, or to the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the drawings; "inside" and "outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0034] In order to solve the problem in the prior art that it is difficult to clean the cross-flow fan blades and the water collecting tank on the bottom shell, the present application provides an air conditioner indoor unit, an air conditioner and a disassembly method of the indoor unit.

[0035] like Figures 1 to 10 As shown, the indoor unit of the air conditioner includes a bottom shell assembly 10, a support structure 20, a panel assembly 40 and a heat exchanger assembly 50. The bottom shell assembly 10 includes a bottom shell 11 and a crossflow fan blade 12, the bottom shell 11 has an air duct, and the crossflow fan blade 12 is rotatably arranged in the air duct. The support structure 20 is used to connect with the wall-mounted plate 30 or the wall 70. The panel assembly 40, the bottom shell 11 and the support structure 20 are surrounded to form an installation cavity. The heat exchanger assembly 50 is arranged on the support structure 20 and is located in the installation cavity; wherein the bottom shell 11 is connected to the support structure 20 and / or the panel assembly 40.

[0036] By applying the technical solution of this embodiment, the panel assembly 40 of the indoor unit of the air conditioner is surrounded by the bottom shell 11 and the support structure 20 to form an installation cavity, the heat exchanger assembly 50 is arranged on the support structure 20 and is located in the installation cavity, and the heat exchanger assembly 50 and the support structure 20 are used to connect with the wall-mounted plate 30 or the wall 70. In this way, since the heat exchanger assembly 50 is installed on the support structure 20 and not installed on the bottom shell assembly 10, when it is necessary to clean the bottom shell assembly 10 (crossflow blades 12 and / or bottom shell 11), it is only necessary to disassemble the bottom shell 11 from the support structure 20 and / or the panel assembly 40 without removing the heat exchanger assembly 50, thereby solving the problem that it is difficult to clean the crossflow blades and the water collecting tank on the bottom shell in the prior art.

[0037] Compared with the prior art in which the heat exchanger assembly is directly installed on a wall panel or a wall, the heat exchanger assembly 50 of the air-conditioning indoor unit in this embodiment is arranged on a supporting structure 20 and is installed on a wall panel 30 or a wall 70 through the supporting structure 20. When the user cleans the bottom shell assembly 10, there is no need to remove the heat exchanger assembly 50, which reduces the cleaning difficulty of the user and improves the user's experience.

[0038] In this embodiment, the bottom shell assembly 10 and the supporting structure 20 are fastened by self-tapping screws, and the wall-mounted plate 30 bears the weight of the bottom shell assembly 10, the supporting structure 20, the heat exchanger assembly 50, the panel assembly 40 and the electrical box 90. When it is necessary to deeply clean the water collection tank and the cross-flow fan blades 12 of the bottom shell 11, after the panel assembly 40 and the electrical box 90 are removed, the bottom shell assembly 10 can be quickly separated from the supporting structure 20, so that the bottom shell 11 and the cross-flow fan blades 12 can be removed for cleaning of individual parts. After cleaning, they can be quickly assembled into the air-conditioning indoor unit.

[0039] Optionally, the heat exchanger assembly 50 is connected to the support structure 20 by snapping and / or fasteners. In this way, the above arrangement makes the assembly and disassembly of the heat exchanger assembly 50 and the support structure 20 easier and simpler, and reduces the difficulty of assembly and disassembly of the two.

[0040] In this embodiment, the heat exchanger assembly 50 and the support structure 20 are snap-fitted and connected by fasteners, thereby improving the connection strength between the two and preventing the two from being separated from each other and affecting the structural stability of the air conditioner indoor unit. Specifically, along the length direction of the support structure 20, the first end of the support structure 20 is snap-fitted with the heat exchanger assembly 50, and the second end of the support structure 20 is connected to the heat exchanger assembly 50 by fasteners. In the process of assembling the heat exchanger assembly 50 and the support structure 20, the assembly positioning is achieved by the snap-fitting cooperation between the two. After the positioning is completed, the two are fastened together by fasteners, thereby improving the assembly accuracy and structural stability of the heat exchanger assembly 50 and the support structure 20.

[0041] like Figures 2 to 6 As shown, the heat exchanger assembly 50 has a first clamping portion 51, and the support structure 20 has a second clamping portion 21. One of the first clamping portion 51 and the second clamping portion 21 is a protrusion, and the other of the first clamping portion 51 and the second clamping portion 21 is a recessed portion. The protrusion extends into the recessed portion and cooperates with the recessed portion. In this way, during the assembly of the heat exchanger assembly 50 and the support structure 20, the above-mentioned arrangement of the first clamping portion 51 and the second clamping portion 21 can play a role in assembly positioning, thereby improving the assembly accuracy of the two. At the same time, after the heat exchanger assembly 50 and the support structure 20 are assembled, the above-mentioned arrangement of the first clamping portion 51 and the second clamping portion 21 makes the disassembly and assembly of the two easier and simpler, thereby reducing the difficulty of disassembly and assembly.

[0042] like Figures 2 to 6 As shown, the heat exchanger assembly 50 has a first connection portion 52, the support structure 20 has a second connection portion 22, and the air conditioner indoor unit further includes a fastener 60. The fastener 60 is arranged on the first connection portion 52 and the second connection portion 22 to fasten the first connection portion 52 and the second connection portion 22. Among them, the second clamping portion 21 and the second connection portion 22 are arranged at intervals along the length direction and / or height direction of the air conditioner indoor unit. Optionally, the fastener 60 is a screw or a bolt. In this way, the above-mentioned arrangement makes it easier and simpler to disassemble and assemble the heat exchanger assembly 50 and the support structure 20, reducing the difficulty of disassembly and assembly of the two.

[0043] Specifically, during the assembly of the heat exchanger assembly 50 and the support structure 20, the first clamping portion 51 and the second clamping portion 21 are first clamped, and then the heat exchanger assembly 50 and the support structure 20 are fastened by the fastener 60, thereby improving the assembly accuracy of the heat exchanger assembly 50 and the support structure 20.

[0044] Optionally, the second clamping portion 21 and the second connecting portion 22 are spaced apart along the length direction of the supporting structure 20, thereby avoiding structural interference during the assembly of the heat exchanger assembly 50 and the supporting structure 20, and making the distribution of the connecting force between the heat exchanger assembly 50 and the supporting structure 20 more reasonable.

[0045] like Figure 6 As shown, the first clamping portion 51 is a protrusion, the second clamping portion 21 is a recess, and the support structure 20 includes a support body 23 and a clamping structure 24. Among them, the support body 23 has an installation space, and at least part of the heat exchanger assembly 50 is located in the installation space. The clamping structure 24 is arranged on the support body 23 and is located in the installation space. The clamping structure 24 includes a first plate 241, a second plate 242 and a third plate 243. The first plate 241 and the third plate 243 are arranged opposite to each other. The first plate 241 is connected to the third plate 243 through the second plate 242. The support body 23 is connected to the first plate 241, the second plate 242 and the third plate 243 to surround and form a recess. In this way, the above arrangement makes the structure of the second clamping portion 21 simpler, easy to process and realize, and reduces the processing cost of the second clamping portion 21.

[0046] Specifically, the protrusion extends into the recess and is limited and stopped by the second plate body 242 to achieve the snap-fitting between the first snap-fitting portion 51 and the second snap-fitting portion 21, thereby making the snap-fitting between the heat exchanger assembly 50 and the support structure 20 easier and simpler.

[0047] It should be noted that the structure of the clamping structure 24 is not limited thereto and can be adjusted according to working conditions and usage requirements. Optionally, the clamping structure 24 further includes a fourth plate body, which is connected to the first plate body 241, the second plate body 242, the third plate body 243 and the support body 23, so that there is a gap between the second plate body 242 and the support body 23 to surround and form a recess.

[0048] like Figures 2 to 5 As shown, the heat exchanger assembly 50 includes a heat exchanger body 53 and an angle frame 54. The angle frame 54 is arranged at the end of the heat exchanger body 53, and the protrusion is arranged on the angle frame 54. The protrusion includes a fifth plate 511 and a sixth plate 512. The sixth plate 512 is connected to the fifth plate 511 and is arranged at a first angle with the fifth plate 511. Among them, the second plate 242 has an opening 2421, and the sixth plate 512 is inserted into the opening 2421 so that the fifth plate 511 and the second plate 242 are limited and stopped. In this way, the above arrangement makes the structure of the first clamping portion 51 simpler, easy to process and realize, and reduces the processing cost of the first clamping portion 51.

[0049] Specifically, the opening 2421 extends in the depth direction of the recess, and the sixth plate 512 is disposed in the middle of the fifth plate 511 and forms a "T"-shaped structure with the fifth plate 511. During the assembly of the protrusion and the recess, the protrusion is inserted into the recess so that the sixth plate 512 is inserted into the opening 2421, and the fifth plate 511 and the second plate 242 are limited and stopped, thereby achieving the snap-fitting of the protrusion and the recess.

[0050] In this embodiment, the angle frame 54 is snap-fitted to the heat exchanger body 53 , and the electric heating structure 55 is connected to the heat exchanger body 53 by screws or bolts.

[0051] like Figure 4 and Figure 6 As shown, the second connection part 22 is a screw column, the first connection part 52 is arranged on the heat exchanger body 53, and the first connection part 52 includes a connection plate 521. The connection plate 521 has a mounting hole 522, and the fastener 60 is inserted into the mounting hole 522 and the screw column. Among them, the connection plate 521 is used to abut against the screw column, and the mounting hole 522 is a waist-shaped hole. In this way, when the staff assembles the first connection part 52 and the second connection part 22, the connection position can be fine-tuned according to the relative position between the two, that is, the fastener 60 can be made to slide in the waist-shaped hole to achieve fine-tuning, thereby preventing interference between the heat exchanger assembly 50 and the support structure 20 and failing to be fastened and connected by the fastener 60.

[0052] In this embodiment, the end surface of the bottom shell 11 facing the support structure 20 is arranged in contact with the support structure 20. In this way, the above arrangement improves the sealing performance of the joint between the bottom shell 11 and the support structure 20, and prevents dust and other impurities from entering the installation cavity through the joint between the two.

[0053] It should be noted that the end surface of the bottom shell 11 facing the support structure 20 is arranged in close contact with the support structure 20, which means that the end surface of the bottom shell 11 facing the support structure 20 is in contact with the support structure 20 to improve the sealing reliability of the connection between the two.

[0054] like Fig. 9 As shown, the heat exchanger body 53 includes a first body 531 and a second body 532, the second body 532 and the first body 531 are arranged at a second angle, and the second body 532 is located at the rear side of the first body 531. The bottom shell 11 covers a portion of the second body 532. In this way, since the bottom shell 11 only covers a portion of the second body 532, it is ensured that the bottom shell 11 can be removed from the support structure 20 and / or the panel assembly 40 without removing the heat exchanger body 53.

[0055] In this embodiment, the panel assembly 40 includes a panel body part 41 and a panel 42 which are connected to each other.

[0056] like Figure 8 As shown, the air conditioner indoor unit further includes a drain pipe 111, which is disposed on the bottom shell 11 to drain the liquid in the air conditioner indoor unit.

[0057] The present application also provides an air conditioner, including an air conditioner indoor unit, and the air conditioner indoor unit is the air conditioner indoor unit mentioned above.

[0058] The present application also provides a method for disassembling an indoor unit, the method for disassembling the indoor unit of the air conditioner described above, and the method for disassembling comprises the following steps:

[0059] Step S1: Remove the panel assembly 40 of the air conditioner indoor unit;

[0060] Step S2: The bottom casing assembly 10 of the air conditioner indoor unit is removed from the supporting structure 20 so as to clean the cross-flow blades 12 and the bottom casing 11 of the bottom casing assembly 10 .

[0061] Specifically, when it is necessary to clean the bottom shell assembly 10, remove the panel 42, the wind direction adjustment structure 110, the panel body part 41, the filter 80 and the electrical box 90, clean the filter 80 and the fins of the heat exchanger body 53, and then remove the bottom shell 11, the motor 100 and the cross-flow fan blades 12 in turn, so that the heat exchanger assembly 50 and the supporting structure 20 remain on the wall-mounted plate 30, and clean the water collection tank, the drain pipe 111 and the cross-flow fan blades 12 on the bottom shell 11 without collecting the refrigerant and removing the internal and external unit connections and power cords.

[0062] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0063] The panel assembly of the indoor unit of the air conditioner, the bottom shell and the supporting structure form an installation cavity, the heat exchanger assembly is arranged on the supporting structure and is located in the installation cavity, and the heat exchanger assembly and the supporting structure are used to connect with the wall-mounted plate or the wall. In this way, since the heat exchanger assembly is installed on the supporting structure and not on the bottom shell assembly, when the bottom shell assembly (crossflow fan blades and / or bottom shell) needs to be cleaned, it is only necessary to disassemble the bottom shell from the supporting structure and / or the panel assembly without removing the heat exchanger assembly, thereby solving the problem in the prior art that it is difficult to clean the crossflow fan blades and the water collection tank on the bottom shell.

[0064] Compared with the prior art in which the heat exchanger assembly is directly installed on a wall-mounted panel or a wall, the heat exchanger assembly of the air-conditioning indoor unit in the present application is arranged on a supporting structure and is installed on the wall-mounted panel or the wall through the supporting structure. When the user cleans the bottom shell assembly, there is no need to remove the heat exchanger assembly, which reduces the cleaning difficulty of the user and improves the user's experience.
