[0024] First, the controller of the existing indoor unit of the air conditioner is described.

[0025] At present, the indoor unit box of air conditioner, because the electrical control components need to be wired into the indoor unit controller box to connect the computer board, so multiple wiring ports are opened on the side and bottom surface of the controller box. At the same time, in order to ensure the modularization of the whole machine and the interchangeability between models, there are multiple model universal controller boxes. This results in that the controller box wiring port can only be reserved according to the model with more functions and more wire harnesses, and the model with less functions and less wire harnesses will leave larger gaps at the wiring port position, and insects and some reptiles will enter the controller box through these gaps, causing the computer board to be short-circuited and damaged. Therefore, how to avoid insects and reptiles entering the controller box through the wiring port of the indoor unit controller box has become a technical problem to be solved in the field. In view of this, the following embodiments are proposed.

[0026] Embodiment one,

[0027] As Figure 1 , Figure 2 shown, in order to solve the problem that insects and reptiles enter the controller box 1 through the wiring port of the indoor unit controller box 1, causing the computer board to be short-circuited and damaged, the controller for the indoor unit of the air conditioner comprises a box 1, the box 1 is provided with a wire inlet port 11, the wire inlet port 11 is provided with a shielding structure, and the shielding area of the shielding structure is adjustable so that the shielding structure can shield the remaining area of the wire inlet port 11. Specifically, the shielding structure is a virtual broken block 12, the connection between the virtual broken block 12 and the wire inlet port 11 is provided with a connecting block 13, along the direction away from the virtual broken block 12, the thickness of the connecting block 13 gradually decreases so that the easy-to-break point is arranged on the wire inlet port 11, thereby forming an easy-to-break point at the connection between the virtual broken block 12 and the wire inlet port 11. The virtual broken block 12 can be broken at the easy-to-break point to adjust the remaining area of the wire inlet port 11, and the virtual broken block 12 is provided with a plurality of virtual broken blocks 12, which are arranged in parallel along the vertical direction, and the adjacent two virtual broken blocks 12 abut each other.

[0028] In the use process of the controller for the indoor unit of the air conditioner in the embodiment, in the initial state, considering that the wire harness will inevitably pass through the wire inlet 11 of the controller box 1, the virtual breaking block 12 does not completely shield the wire inlet 11, but reserves part of the area for wire inlet at the wire inlet 11. Then, the function and the number of wire harnesses of the indoor unit of the air conditioner are determined based on the model of the indoor unit of the air conditioner. If the function of the indoor unit of the air conditioner is small and the number of wire harnesses is small, the wire inlet area at the wire inlet 11 does not need to be adjusted, and the reserved wire inlet area can meet the accommodation requirement of the wire harness. If the function of the indoor unit of the air conditioner is large and the number of wire harnesses is large, the virtual breaking block 12 can be moved in the order from top to bottom. Since the connecting block 13 is arranged at the connecting position of the virtual breaking block 12 and the wire inlet 11, and the thickness of the connecting block 13 gradually decreases in the direction away from the virtual breaking block 12, the easy breaking point is formed at the connecting position of the virtual breaking block 12 and the wire inlet 11, so that the virtual breaking block 12 is broken at the easy breaking point. After the virtual breaking block 12 is broken, the virtual breaking block 12 can be removed, the wire inlet area at the wire inlet 11 is increased to accommodate more wire harnesses, and the virtual breaking block 12 that is not broken can continue to shield the remaining wire inlet area at the wire inlet 11, thereby solving the problem that insects and reptiles enter the controller box 1 through the wire inlet of the controller box 1 of the indoor unit to cause short circuit and damage of the computer board.

[0029] The above setting mode has the advantages that the controller box 1 for the indoor unit of the air conditioner can adjust the wire inlet area and the size of the remaining wire inlet area at the wire inlet 11 based on different models of the indoor unit of the air conditioner, so that the wire inlet area of the wire inlet 11 can meet the wire inlet requirement, the remaining wire inlet area is shielded to prevent insects and reptiles from entering the box 1, the structure is simple, the operation is convenient, and the existing problems are solved. In addition, the connecting block 13 at the connecting position of the virtual breaking block 12 and the wire inlet 11 is arranged in the direction away from the virtual breaking block 12, the thickness of the connecting block 13 gradually decreases, and the easy breaking point is arranged on the wire inlet 11. In this way, after the virtual breaking block 12 is broken and removed, the remaining structure of the connecting block 13 will not leave residual cutting or wear the wire harness, and the service life of the wire harness is guaranteed.

[0030] In the foregoing embodiment, it is mentioned that the plurality of virtual breaking blocks 12 are arranged in parallel along the vertical direction and abut each other between adjacent two virtual breaking blocks 12. Although this arrangement can make the adjacent virtual breaking blocks 12 fit more closely, the virtual breaking block 12 is connected to the side wall of the wire inlet 11 only at two sides through the connecting block 13, and the easy breaking point is formed at the connecting position, which may cause the connection strength between the virtual breaking block 12 and the wire inlet 11 to be too low, so that the virtual breaking block 12 cannot bear the weight of the wire harness and automatically breaks. In order to improve this problem, the present embodiment is proposed. As shown in FIG. 6, the virtual breaking block 12 is arranged in the form of a plate, and the plate-shaped virtual breaking block 12 is connected to the side wall of the wire inlet 11 through the connecting block 13 arranged on the side wall of the wire inlet 11.Figure 1 、 Figure 2 As shown in FIG. 1, in one possible implementation, the dummy block 12 is provided with a plurality of dummy blocks 12 arranged in parallel along the vertical direction, and a connecting block 13 is arranged between the adjacent two dummy blocks 12, and a breakable point is arranged between the connecting block 13 and the adjacent two dummy blocks 12, and the adjacent two dummy blocks 12 can be broken through the breakable point to adjust the remaining area of the wire inlet at the wire inlet port 11.

[0031] The above-mentioned embodiment has the advantages that, compared with the abovementioned connecting mode in which the adjacent two dummy blocks 12 abut against each other, the present embodiment connects the top surface and the bottom surface of the adjacent two dummy blocks 12 by arranging the connecting block 13 between the adjacent two dummy blocks 12, thereby enhancing the support strength of the dummy block 12 in the vertical direction, and thus solving the above-mentioned problem. In addition, the present embodiment further arranges the breakable point between the adjacent two dummy blocks 12, and when it is needed to remove the dummy block 12 located above, the breakage between the dummy block 12 located above and the dummy block 12 located below is facilitated. It can be understood by those skilled in the art that the arrangement mode of the breakable point between the adjacent two dummy blocks 12 in the present embodiment can be selected to arrange the breakable point on the dummy block 12 located above, or to arrange the breakable point on the dummy block 12 located below, or to arrange the breakable point on the connecting block 13, and preferably, the breakable point is arranged on the dummy block 12 located below, so that when the dummy block 12 is removed in a top-down manner, the remaining structure of the connecting block 13 can be taken down completely, avoiding that the remaining structure of the connecting block 13 leaves residual cutting or wears the wire harness, and thus the service life of the wire harness is guaranteed.

[0032] In addition, as to the arrangement mode between the plurality of virtual broken blocks 12, although the above-mentioned is that the plurality of virtual broken blocks 12 are arranged in parallel along the vertical direction, this is not the only setting mode, and the person skilled in the art can also set the plurality of virtual broken blocks 12 along the horizontal direction or along any other direction, as to the length of the connecting block 13, the length of the connecting block 13 can be set to be relatively short but the number is large as shown in the drawings, or the length of the connecting block 13 can be set to be relatively long but the number is small, for example, the length of the connecting block 13 in the horizontal direction is set to be consistent with the length of the virtual broken block 12, or the length of the connecting block 13 in the vertical direction is set to be consistent with the width of the virtual broken block 12, it should be noted that the length form of the connecting block 13 shown in the drawings can be easily removed when the virtual broken block 12 needs to be broken, but the support strength of the wire harness is relatively weak, and the length form of the connecting block 13 of the latter can provide stronger support strength to the wire harness, but when the virtual broken block 12 needs to be broken, it can be more laborious, and the person skilled in the art can reasonably set the length of the connecting block 13 according to the actual needs, and these changes do not exceed the technical principles of the utility model, therefore, they are also included in the protection scope of the utility model.

[0033] As shown in Figure 1 , Figure 2 Although the above-mentioned is that the connecting block 13 is arranged between the virtual broken block 12 and the wire inlet 11 and between the adjacent two virtual broken blocks 12, and two length forms of the connecting block 13 are mentioned in the above-mentioned embodiment, there is still a remaining area of the connecting block 13 between the virtual broken block 12 and the wire inlet 11 and between the adjacent two virtual broken blocks 12, and a gap exists in the remaining area of the connecting block 13, insects or other small-sized reptiles can enter the controller box 1 from the gap, in order to solve this problem, the present embodiment is proposed, in the present embodiment, the shielding structure further comprises a shielding plug (not shown in the drawings), there is a remaining area of the connecting block 13 between the virtual broken block 12 and the wire inlet 11 and / or between the adjacent two virtual broken blocks 12, and a gap is formed in the remaining area of the connecting block 13, and the shielding plug can be embedded in the gap formed in the remaining area of the connecting block 13.

[0034] The above-mentioned setting mode has the advantages that by embedding the shielding plug in the gap formed in the remaining area of the connecting block 13 between the virtual broken block 12 and the wire inlet 11 and between the adjacent two virtual broken blocks 12, the gap formed in the remaining area of the connecting block 13 is blocked, and the problem that insects or other small-sized reptiles can enter the controller box 1 from the gap to cause the computer board to be short-circuited and damaged is further avoided.

[0035] Embodiment two,

The shielding structure further comprises a spring (not shown in the figure), the spring is arranged in the containing groove and connected with one end of the containing groove and the other end of the baffle, and the spring is in a compressed state to enable the baffle to extend under the action of the spring.

[0037] The above-mentioned embodiment has the advantages that by arranging the containing groove on the box 1, arranging the sliding groove at the wire inlet 11, and arranging the spring in the containing groove, in the initial state, the baffle is extruded by the spring in the compressed state and slides out of the containing groove along the sliding groove and abuts on the wire inlet 11, when the wire inlet 11 needs to access the wire harness, only the baffle needs to be pressed downward, the baffle retracts into the containing groove along the sliding groove and compresses the spring, after the wire harness is placed, the baffle is released, the baffle abuts on the wire harness again under the extrusion of the spring, the wire harness is fixed, and the remaining area of the wire inlet 11 below the wire inlet 11 is shielded, so that the problem that insects and reptiles enter the controller box 1 through the wire outlet of the controller box 1 of the indoor unit to cause short circuit and damage of the computer board is avoided.

[0038] It should be noted that the above-mentioned embodiment is only used to illustrate the principle of the utility model, and is not intended to limit the protection scope of the utility model, and those skilled in the art can adjust the above-mentioned structure without departing from the principle of the utility model, so that the utility model can be applied to more specific application scenarios.
