[0018] The lateral area is defined as: a range of 0.05L-0.9L in a panel direction of a front side of the front frame assembly 1 from C as a starting point; wherein a machine body width dimension is set as W from a top view perspective of the machine body, a machine body depth dimension at 1 / 2W of the machine body width dimension is L, and the intersection of a center line at 1 / 2W of the machine body width and the rear frame assembly 2 is C; and the fan assembly is arranged to have at least one centrifugal fan.

[0019] The air inlet assembly comprises an air inlet 4 and at least one centrifugal fan, and the air inlet 4 is arranged on the defined lateral area to form a rear lateral air inlet, so that when the air conditioner cabinet is arranged in a front-to-back manner against a wall, the air inlet 4 is not blocked by the wall, the air inlet amount is considerable, and the back of the air conditioner cabinet can be placed closer to the wall or in a corner of the wall, thereby saving indoor space.

[0020] As shown in Figure 2 and Figure 3 According to another embodiment of the utility model, a kind of air inlet assembly based on simple centrifugal air duct, wherein the cross section of the front frame assembly 1 is square and the cross section of the rear frame assembly 2 is semicylindrical, and the lateral area is on the arc surface of the rear side of the rear frame assembly 2.

[0021] In the embodiment, the front frame assembly 1 is a square shell, and the rear frame assembly 2 is a semicylindrical shell, i.e., the entire machine body is uniformly spliced by the square shell in front and the semicylindrical shell behind. Specifically, the lateral area is only on the arc surface of the semicylindrical shell behind, which is referred to as the rear lateral area; the air inlets 4 are all arranged on the rear lateral area.

[0022] Based on the above scheme:

[0023] The air inlets 4 and the fan assembly are provided with an evaporator 3; when the air inlets 4 are all located on the same side of the center line of the rear frame assembly 2, the central axis of the curved section 31 in the middle of the cross section of the evaporator 3 is located on the same side of the center line of the rear frame assembly 2. Assuming that there are three air inlets 4, all located on the left side of the rear frame assembly 2, the central axis of the curved section 31 in the middle of the cross section of the evaporator 3 is also designed to the left side of the rear frame assembly 2, which can make the effective heat exchange area of the evaporator 3 larger, and the air exchange capacity of the air entering the machine body from the air inlets 4 better.

[0024] According to another embodiment of the utility model, a kind of air inlet assembly based on simple centrifugal air duct, wherein the fan assembly is set as a centrifugal fan, i.e., the air conditioner cabinet only uses a centrifugal fan as the power for air suction, and all air inlets 4 are introduced by the centrifugal fan and the simple centrifugal air duct matched with the centrifugal fan.

[0025] As shown in Figure 4 and Figure 5 According to another embodiment of the utility model, a kind of air inlet assembly based on simple centrifugal air duct, wherein the air inlets 4 are all arranged at least one on different sides of the center line of the rear frame assembly 2, and each air inlet 4 is a basic air inlet 41 or a combination of a basic air inlet 41 and at least one additional air inlet 42.

[0026] Here is: there are 2 basic air inlets 41, 2 basic air inlets 41 can be symmetrically arranged, or asymmetrically arranged; and additional air inlets 42 can have or not have, additional air inlets 42 can be arranged inside the basic air inlets 41 or outside, as long as it is within the scope of the rear lateral area.

[0027] Wherein, each of the basic air inlets 41 and the additional air inlets 42 is a long strip square opening arranged longitudinally from top to bottom, and a plurality of air inlet flaps 5 are arranged in each long strip square opening, and the number of air inlet flaps 5 is not more than five. Each basic air inlet 41 and additional air inlet 42 is designed in shape to meet the requirement of having sufficient air inlet amount; specifically, the number of air inlet flaps 5 can be 2, 3, 4 or 5, which can be designed according to actual needs.

[0028] At the same time, the rear frame assembly 2 is provided with a multi-section detachable filter screen matched with the air inlets 4, and the number of sections of the multi-section detachable filter screen is not more than three. The multi-section detachable filter screen is slid into the filter screen mounting position arranged in the rear frame assembly 2 to filter the air entering each air inlet 4, thereby reducing the content of dust and the like in the air entering the air conditioner cabinet. The multi-section detachable filter screen can be a two-section detachable filter screen or a three-section detachable filter screen.

[0029] Specifically in this embodiment, the air inlets 4 are each provided with one basic air inlet 41 on different sides of the center line of the rear frame assembly 2. Then, the air conditioner cabinet has two basic air inlets 41, and the two basic air inlets 41 are symmetrically distributed in the left rear lateral area and the right rear lateral area of the rear frame assembly 2. The air conditioner cabinet is configured to have upper rear side air inlet to have sufficient air inlet amount.

[0030] Because the evaporator 3 in the air conditioner cabinet is designed with a certain curvature to meet the installation requirement, and the evaporator 3 further includes a longer straight section 32 connected to one end of the curved section 31 and a shorter straight section 33 connected to the other end of the curved section 31, the projection of one basic air inlet 41 on the longer straight section 32 is partially overlapped with the longer straight section 32 to be arranged staggered, and the projection of the other basic air inlet 41 on the shorter straight section 33 completely covers the shorter straight section 33. Such design is beneficial to improve the air inlet amount on both sides of the machine body, so that the heat exchange between the evaporator 3 and the air inlet is more uniform, the heat exchange effect is better, and thus the performance of the air conditioner cabinet is improved.

[0031] As Figure 5As shown, according to another embodiment of the utility model, the kind of simple centrifugal air duct based on air inlet subassembly, wherein the arc line formed by the cross section of the basic air inlet 41 is connected between the midpoint of the chord line of the arc line formed by the cross section of rear frame assembly 2 two endpoints respectively, line A and line B, the angle between line A and line B and horizontal line is a and b respectively, specific a is 5 DEG, b is 50 DEG, this setting can improve the air intake of both sides of fuselage, so that the heat exchange of evaporator 3 and air intake is more uniform, and the heat exchange effect is better, thereby improving the performance of air conditioner.

[0032] Finally, it is explained that the above embodiments are only used to illustrate the technical scheme of the utility model and not to limit, although the utility model is described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical scheme of the utility model can be modified or replaced equivalently without departing from the purpose and scope of the technical scheme of the utility model, which should be covered in the scope of claims of the utility model.
