The air conditioner indoor unit 1000 according to the embodiment of the invention is described below with reference to the drawings, and the air conditioner indoor unit 1000 can realize the adjustment of indoor air flow temperature, and is suitable for various indoor occasions such as living rooms, offices, laboratories and the like.

An indoor unit 1000 of an air conditioner according to an embodiment of the present invention, as shown in fig. 1, includes: an air conditioning case 100.

As shown in fig. 2, the air conditioning case 100 includes: back panel 110, two side panels 120, and fasteners. As shown in fig. 3 and 4, the edge of the back plate 110 is provided with a mounting portion 111, where the edge mainly refers to the end side of the plate, not the plate surface.

As shown in fig. 3, two side plates 120 are attached to opposite sides of the back plate 110, such as the left and right sides as shown. The two side plates 120 and the back plate 110 enclose a fitting space 101 therebetween, so that it can be used for mounting other internal components.

As shown in fig. 4, the edge of the side plate 120 is provided with a first mounting edge 121 and a second mounting edge 122 extending in different directions, and a positioning groove 123 is formed between the first mounting edge 121 and the second mounting edge 122, and the positioning groove 123 positions the mounting portion 111. That is, the edge of the side plate 120 facing the back plate 110 forms two first and second mounting edges 121 and 122 extending in a bifurcated manner, and the two mounting edges may be respectively fitted on different sides of the mounting portion 111.

As shown in fig. 4, the fastener connects the second mounting edge 122 and the mounting portion 111 in order from within the mounting space 101, and the fastener does not need to be mounted from the rear side of the back plate 110 to the inside of the mounting space 101, but is fastened from the inside mounting space 101 toward the side plate 120 and the back plate 110.

As can be seen from the above structure, the air conditioner indoor unit 1000 according to the embodiment of the present invention can form a certain pre-positioning assembly relationship between the back plate 110 and the side plate 120 through the positioning cooperation of the mounting portion 111 and the positioning groove 123; when the first mounting edge 121 and the second mounting edge 122 are simultaneously abutted against both surfaces of the mounting portion 111, the outer surface of the mounting portion 111 and the inner surface of the positioning groove 123 are closely fitted therewith, and the fastener fastens the second mounting edge 122 and the mounting portion 111 from the fitting space 101, the back plate 110 can be stably coupled with respect to the side plate 120.

In the assembly process, the back plate 110 can be placed on a production line, the inner side surface of the back plate 110 faces upwards, and the two side plates 120 are respectively positioned by hand-held positioning or clamping, so that the two side plates 120 respectively form pre-assembly positioning relative to the back plate 110; the side plates 120 and the back plate 110 are then sequentially tightened with fasteners to form a preliminary mounting frame. In this process, the back plate 110 does not need to be turned over, so that the assembly time required by turning over is saved, and the problem that the side plate 120 falls off from the back plate 110 and is damaged in the process of installation after turning over is avoided. Thus, the air conditioner case 100 of the present application is assembled quickly, and the assembling efficiency of the back plate 110 and the side plate 120 is high.

It can be appreciated that, compare in prior art need carry out the scheme of turn-over to the backplate when fixed curb plate and backplate, the air conditioning case 100 of the air conditioning indoor unit 1000 of this application assembly efficiency is high, the assembly qualification rate is high, workman convenient operation, the installation frame of formation is stable, be convenient for assemble other internals. Compared with the prior art, the air conditioner casing 100 is more flexible and efficient to assemble and is convenient to cooperate with other various components because the scheme of relying on chassis positioning when fixing the side plates and the back plate is needed.

Alternatively, the fasteners are screw members or bolt members, thereby allowing the back panel 110 and the side panels 120 to form a relatively stable connection.

Advantageously, the two side plates 120 are disposed opposite each other, and the connection structure between each side plate 120 and the back plate 110 is substantially similar. For example, in a specific example, the first mounting edges 121 on the two side plates 120 are symmetrically arranged with the central axis of the back plate 110 as a symmetry axis, and the second mounting edges 122 on the two side plates 120 are also symmetrically arranged with the central axis of the back plate 110 as a symmetry axis, so that after the two side plates 120 are assembled on the back plate 110, a main parallel effect can be achieved, which is beneficial to controlling the space size of the assembly space 101 to be sufficient.

In some embodiments of the present invention, as shown in fig. 4, the mounting portion 111 includes a first mounting portion 1111 and a second mounting portion 1112 connected at an angle, that is, an intersection angle is formed between the first mounting portion 1111 and the second mounting portion 1112, and the intersection angle should be matched with an included angle between the first mounting edge 121 and the second mounting edge 122, so that the first mounting portion 1111 can be attached to an inner surface of one side of the positioning groove 123 while the second mounting portion 1112 can be attached to an inner surface of the other side of the positioning groove 123.

Further, as shown in fig. 4, the first mounting portion 1111 is bent and connected to the back plate 110, and the first mounting edge 121 wraps the outer side of the first mounting portion 1111, so that the first mounting portion 1111 is not coplanar with the back plate 110, and the first mounting edge 121 can cover the first mounting portion 1111, so that the first mounting portion 1111 is not exposed, and the aesthetic property and the integrity of the air-conditioning case 100 when viewed from the side are ensured. In a specific example, the first mounting portion 1111 preferably extends toward the outside of the surface of the back plate 110, so that the first mounting portion 1111 can form a large fitting space 101 when the side plate 120 is connected to the back plate 110.

Further, the second mounting portion 1112 extends toward the interior of the mounting space 101, so that the second mounting portion 1112 can be returned to the mounting space 101 again, and the second mounting edge 122 is connected to the second mounting portion 1112, so that the fastener can pass through the second mounting edge 122 and the second mounting portion 1112 in sequence from the mounting space 101. The second mounting portion 1112 provides a sufficient support surface and attachment surface for the second mounting edge 122.

Optionally, the angle between the first mounting portion 1111 and the back plate 110 is an obtuse angle, and then the first mounting portion 1111 extends obliquely outwards along the edge of the back plate 110, and compared with the case that the angle between the first mounting portion 1111 and the back plate 110 is a right angle, the first mounting portion 1111 extending obliquely outwards can provide a larger connecting surface for the first mounting edge 121 and promote a larger edge space of the inner assembly space 101, so as to facilitate assembly of other mating components such as the air inlet grille 210 and the first filter 220 on the side plate 120.

Of course, in other examples, the included angle between the first mounting portion 1111 and the back plate 110 is not limited to an obtuse angle, for example, the included angle between the first mounting portion 1111 and the back plate 110 may be set to be a right angle, and the first mounting portion 1111 extends perpendicular to the surface of the back plate 110, so that the second mounting portion 1112 connected to the first mounting portion 1111 can be separated from the back plate 110 by a certain distance, and a certain space is formed between the second mounting portion 1112, the first mounting portion 1111 and the back plate 110 for avoiding the fastening member, so that the end portion of the fastening member is prevented from piercing the back plate 110, the integrity of the back plate 110 is ensured, and the aesthetic property of the external appearance of the back plate 110 is improved.

Optionally, the angle between the first mounting portion 1111 and the second mounting portion 1112 is acute, which examples are mainly suitable for the case that the first mounting portion 1111 extends obliquely outwards along the edge of the back plate 110, so that the second mounting portion 1112 can correct the situation that the back plate 110 is exposed in the assembly space 101 due to the oblique extension of the first mounting portion 1111, so that the second mounting portion 1112 can cover part of the back plate 110 and avoid fastening of the back plate 110 by a fastener, so that the second mounting portion 1112 can form a positioning fit with the second mounting edge 122 instead of the back plate 110, and further fastening connection.

In other examples, the angle between the first mounting portion 1111 and the second mounting portion 1112 is not limited to the aforementioned acute angle, and may be, for example, a right angle, and these examples are mainly applicable to a case where the first mounting portion 1111 extends perpendicular to the plane of the back plate 110, so that the second mounting portion 1112 can be spaced from the back plate 110, and in a case where the second mounting portion 1112 is substantially parallel to the plane of the back plate 110, so that a sufficient mounting surface is provided for the second mounting edge 122, and the mounting surface is visible.

Advantageously, as shown in fig. 4, the mounting portion 111 further includes a third mounting portion 1113, where the third mounting portion 1113 is connected to the second mounting portion 1112, and the third mounting portion 1113 extends toward the back plate 110, so that the third mounting portion 1113 can further cover a gap formed between the second mounting portion 1112 and the back plate 110, so that a space enclosed between the first mounting portion 1111, the second mounting portion 1112, the third mounting portion 1113, and the back plate 110 is relatively closed, and the edge of the second mounting portion 1112 is effectively prevented from scratching other components to be mounted in the mounting space 101, and the overall local strength of the mounting portion 111 is also higher, so that the mounting portion 111 is not easy to deform after the fastener is mounted. In these examples, the mounting portion 111 is turned three times relative to the back plate 110, thereby forming a relatively stable hemming assembly.

In the description of the present invention, a feature defining "a first", "a second", and a third "may explicitly or implicitly include one or more of the feature for distinguishing between the described features, no sequential or heavy or no fractional.

Advantageously, the second mounting portion 1112 is disposed parallel to the back plate 110, so that the second mounting portion 1112 is spaced apart from the back plate 110 in the front-rear direction in the drawing, and the second mounting portion 1112 is located in the mounting space 101, and the second mounting portion 1112 is fastened to the second mounting edge 122 by a fastener.

Alternatively, the mounting parts 111 are generally arranged along the height direction of the back plate 110, and the mounting parts 111 located at both side edges of the back plate 110 are respectively formed to be bent toward the inside a plurality of times, so that the mounting parts 111 have not only a certain positioning angle but also a corresponding mounting surface, and also sufficient strength.

Advantageously, the side plate 120 is an injection molded integral part, and when the side plate 120 is inadvertently dropped during the installation process, the side plate 120 can be restored even if the side plate 120 is deformed to a certain extent, so as to reduce the probability of scrapping the side plate 120 due to misoperation during the installation process.

Advantageously, as shown in fig. 5, 6 and 7, the side plate 120 is provided with a reinforcing rib 128, and the reinforcing rib 128 is connected between the side plate 120 and the second mounting edge 122, so that stability of the second mounting edge 122 relative to the side plate 120 is improved, cracking of the second mounting edge 122 and the second mounting portion 1112 in the fastening process is avoided, and local strength of the side plate 120 and stability of the fastener after being mounted are improved. In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more.

Optionally, the plurality of reinforcing ribs 128 are disposed at intervals along the height direction of the side plate 120, so as to ensure the structural strength of the side plate 120, facilitate the side plate 120 to form multiple fastening with the back plate 110, reduce the gap between the side plate 120 and the back plate 110 after installation, and reduce abnormal noise.

Advantageously, a portion of the side plate 120 adjacent to the back plate 110 is folded and extended inward, so that the first mounting edge 121 and the second mounting edge 122 provided at the ends of the side plate 120 can be better engaged with the mounting portion 111 on the back plate 110.
