[0030] The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present utility model, and should not be construed as a limitation to the present utility model.

[0031] Please refer to the following Figures 1 to 8 The indoor unit of an air conditioner according to an embodiment of the present invention is described.

[0032] like Figures 1 to 4 and Figure 8 As shown, the indoor unit of the air conditioner of the embodiment of the present invention includes: a housing 1, an evaporator 2, an air guide frame 3, a sweeping assembly 4 and an electronic control module 5. The sweeping assembly 4 includes a sweeping blade 41 and a sweeping motor 42, and the electronic control module 5 includes an electronic control box 51 and an electronic control board 52.

[0033] The housing 1 is provided with an air inlet 121 and an air outlet 122. The air guide frame 3 and the evaporator 2 are both installed in the housing 1. The air guide frame 3 is provided with an air guide channel 31, which is communicated with the air outlet 122. The wind sweeping blade 41 is provided in the wind guide channel 31. The wind sweeping motor 42 is transmission-connected to the wind sweeping blade 41. The wind sweeping motor 42 has a motor line 421. The electric control board 52 is provided in the electric control box 51. The electric control box 51 is provided in the length direction of the evaporator 2 (such as Figure 1 On one side of the left and right directions), a first wiring portion 55 is provided on the electric control box 51. The first wiring portion 55 is provided on the lower side of the air guide frame 3 and is arranged adjacent to the wind sweeping motor 42. The motor line 421 passes through the first wiring portion 55 and is connected to the electric control board 52.

[0034] According to the embodiment of the air conditioner indoor unit of the present invention, by arranging the first wiring portion 55 on the lower side of the air guide frame 3, when the operator installs the guide frame on the housing 1, the air guide frame 3 does not block or interfere with the first wiring portion 55. Moreover, since the first wiring portion 55 is arranged adjacent to the air sweep motor 42, the length of the motor cable 421 can be shortened, and the motor cable 421 can be easily introduced into the electrical control box 51 through the first wiring portion 55. Therefore, the wiring method of the air conditioner indoor unit of the embodiment of the present invention is simple, and assembly is convenient, which is conducive to improving production efficiency.

[0035] It is understood that during the assembly process of the air conditioner indoor unit, the electrical control box 51 must be assembled before the air guide frame 3. In the related art, after the air guide frame 3 is assembled, it blocks the original wire inlet of the electrical control box 51, making it difficult to insert the motor wire 421 of the air sweep motor 42 from the wire inlet into the electrical control box 51, causing difficulties in wiring the air conditioner indoor unit.

[0036] The air conditioner indoor unit of the embodiment of the present invention arranges the first wiring portion 55 on the lower side of the air guide frame 3 and adjacent to the wind sweeping motor 42. This prevents the wiring of the motor wire 421 from being affected by the assembly of the air guide frame 3, and does not extend the arrangement path of the motor wire 421 excessively, thereby reducing the cost of the motor wire 421 and helping to reduce electrical safety hazards.

[0037] Alternatively, asFigure 3 and Figure 4 As shown in Figure 4 , the electronic control module 5 further includes a ground wire plate 53 and a first ground wire 54. The ground wire plate 53 is disposed inside the electronic control box 51. Two ends of the first ground wire 54 are respectively connected to the evaporator 2 and the ground wire plate 53. The first ground wire 54 passes through the first wire routing portion 55. It can be understood that the evaporator 2 needs to be grounded to improve the electrical safety during the operation of the indoor unit of the air conditioner. Since the first ground wire 54 also passes through the first wire routing portion 55, the structure of the first wire routing portion 55 can be fully utilized, and the wiring is convenient, which is beneficial to reducing the assembly man-hours.

[0038] For example, as Figure 1 shown, a grounding portion 21 is provided on one side of the evaporator 2 adjacent to the electronic control box 51 (such as Figure 1 the right side of the evaporator 2 in Figure 1 ). The grounding portion 21 is connected to the first ground wire 54.

[0039] Specifically, as Figure 4 shown, both the first wire routing portion 55 and the ground wire plate 53 are disposed on one side of the electronic control box 51 adjacent to the evaporator 2, and the first wire routing portion 55 is disposed above the ground wire plate 53. Thus, the path of the motor wire 421 extending downward can be shortened, and the probability of the motor wire 421 coming into contact with the condensed water on the side wall of the evaporator 2 can be reduced. On the one hand, the electrical safety during the operation of the indoor unit of the air conditioner can be improved. On the other hand, the winding of the motor wire 421 can be reduced, and the production cost can be lowered.

[0040] Furthermore, the electronic control module 5 further includes a second ground wire (not shown). Two ends of the second ground wire are respectively connected to the ground wire plate 53 and the electronic control board 52. It can be understood that the electronic control board 52 is also connected to the ground wire plate 53 through the second ground wire to improve the electrical safety of the electronic control board 52.

[0041] Optionally, as Figures 2 to 4 shown, the electronic control box 51 includes a box body 511 and an electronic control cover 512. The electronic control cover 512 is detachably mounted on the front side of the box body 511. The electronic control cover 512 and the box body 511 enclose an electronic control cavity 513. The ground wire plate 53 and the electronic control board 52 are both disposed inside the electronic control cavity 513. The first wire routing portion 55 is provided on the box body 511. It can be understood that the housing 1 includes a base 11 and a frame body 12. The air inlet 121 and the air outlet 122 are both provided on the frame body 12. The frame body 12 is located on the front side of the base 11. When the operator removes the frame body 12, since the electronic control cover 512 is detachably mounted on the front side of the box body 511, the operator only needs to remove the electronic control cover 512 to repair the electronic control board 52 and the circuits inside the electronic control box 51, which improves the convenience during the maintenance of the indoor unit of the air conditioner.

[0042] It should be noted that when the indoor unit of the air conditioner is hung on the wall, the electronic control cover 512 is disposed on the side of the front wall surface of the electronic control cover 512 facing the frame body 12. After the frame body 12 is removed, the operator can conveniently detach the electronic control cover 512 from the box body 511, so as to facilitate the operator to repair the circuits in the box body 511.

[0043] For example, as Figures 4 to 6 shown, the first wire routing portion 55 is a notch, and a first opening 551 is provided on one side of the notch adjacent to the electronic control cover 512. The electronic control cover 512 seals the first opening 551. It can be understood that the motor wire 421 can be pressed into the first wire routing portion 55 (notch) through the first opening 551, and then the electronic control cover 512 is installed. In this way, the motor wire 421 can be fixed, and it is also convenient for the manufacturing of the electronic control box 51, with a relatively low cost.

[0044] In other examples, the first wire routing portion 55 can also be a wire routing hole, or other wire routing buckle structures, and the present application does not limit this.

[0045] Specifically, as Figure 7 shown, a wire winding portion 59 is provided on the box body 511. The wire winding portion 59 is located outside the electronic control cavity 513 and defines a wire winding channel 591 with the first wire routing portion 55. The first ground wire 54 and the motor wire 421 are arranged in the wire winding channel 591. Under the restraint of the wire winding portion 59, the first ground wire 54 and the motor wire 421 can be fixed in the first wire routing portion 55, thereby reducing the probability of the first ground wire 54 and the motor wire 421 coming out of the first opening 551 and improving the stability after the wire harness is installed.

[0046] Optionally, as Figures 4 to 6 shown, a receiving groove 5111 is provided in the box body 511, and the receiving groove 5111 is located on the side of the box body 511 adjacent to the electronic control cover 512. In other words, the receiving groove 5111 is provided at the opening position at the front end of the box body 511. The ground wire plate 53 is installed in the receiving groove 5111, so that the ground wire plate 53 can be fixed at the opening position at the front end of the box body 511.

[0047] Compared with the solution of "the ground wire plate 53 is disposed at the bottom of the box body 511", it is convenient for the operator to connect the first ground wire 54 and the second ground wire to the ground wire plate 53. In other words, since the space inside the box body 511 is narrow and it is not convenient for the operator's hand or tool to be inserted into the box body 511, in the present application, the ground wire plate 53 is fixed at the opening position at the front end of the box body 511, which is convenient for the operator's wiring work.

[0048] In some embodiments, as Figures 4 to 7As shown, the electric control box 51 is provided with a second wiring portion 56 and a third wiring portion 57, which are arranged on the upper and lower sides of the electric control box 51 respectively. The air conditioner indoor unit also includes a control wiring harness, part of which is passed through the second wiring portion 56, and the other part of the control wiring harness is passed through the third wiring portion 57. The control wiring harness is connected to the electric control board 52.

[0049] It is understood that the control wiring harness can be electrical control circuits for wind turbine motors, display modules, heaters, and the like. Because the second wiring portion 56 and the third wiring portion 57 are arranged on the upper and lower sides of the electrical control box 51, respectively, a portion of the control wiring harness can be introduced from the top of the electrical control box 51, while another portion can be introduced from the bottom. This avoids wiring difficulties caused by centralized wiring and helps improve the electrical safety of the circuits.

[0050] In addition, since the motor wire 421 and the first ground wire 54 are separately introduced into the electric control box 51 from the first wiring portion 55, the convenience of wiring the motor wire 421 and the first ground wire 54 can be improved, which is conducive to improving assembly efficiency.

[0051] Alternatively, as Figure 5 and Figure 6 As shown, a second opening 561 is defined on a side of the second wiring portion 56 adjacent to the electrical control cover 512, and a third opening 571 is defined on a side of the third wiring portion 57 adjacent to the electrical control cover 512. The electrical control cover 512 covers both the second opening 561 and the third opening 571. It will be appreciated that the control wiring harness can be pressed into the second wiring portion 56 through the second opening 561 and into the third wiring portion 57 through the third opening 571, thereby improving the convenience of wiring the control wiring harness. Furthermore, the electrical control cover 512 can cover both the second opening 561 and the third opening 571 to prevent the control wiring harness from becoming loose, thereby improving the reliability of the control wiring harness arrangement.

[0052] Alternatively, as Figure 5 and Figure 6 As shown, a wiring channel 58 is provided in each of the second wiring portion 56 and the third wiring portion 57. A wire blocking block 583 is provided in the wiring channel 58, and the wire blocking block 583 is provided on one side of the wiring channel 58 adjacent to the electric control cover 512. It can be understood that the wire blocking block 583 can reduce the probability of the control wiring harness escaping from the wiring channel 58, thereby improving the stability of the control wiring harness after installation.

[0053] Taking the second wiring portion 56 as an example, the wire block 583 is disposed at a position adjacent to the second opening 561 of the wiring channel 58, that is, the wire block 583 is disposed on a side of the wiring channel 58 adjacent to the electrical control cover 512. Due to the arrangement of the wire block 583, the gap of the second opening 561 at that position can be reduced, thereby reducing the probability of the wire harness pressed into the wiring channel 58 escaping from the second opening 561.

[0054] Among them, the wire blocking block 583 can be arranged at the inlet end position of the wire routing channel 58 or at the outlet end position of the wire routing channel 58. This application does not limit this.

[0055] Optionally, as Figure 7 shown, the wire routing channel 58 includes a first section 581 and a second section 582 that are interconnected, and the axial direction of the first section 581 and the axial direction of the second section 582 are arranged orthogonally. It can be understood that the extension path of the wire routing channel 58 is generally in an "L" shape. When the control wire harness is arranged in the wire routing channel 58 with the above structure, position constraints can be achieved through the wire routing channel 58. When the control wire harness is stretched, the wire routing channel 58 can limit the movement of the control wire harness within a certain range to reduce the traction force on the wiring position of the control wire harness and the electronic control board 52, thereby improving the reliability of the control wire harness arrangement.

[0056] In one example, as Figure 5 and Figure 6 shown, in the front-rear direction of the housing 1, the depth of the wire routing channel 58 is greater than the depth of the first wire routing portion 55. In other words, the depth of the wire routing channel 58 in the front-rear direction of the housing 1 is greater than the depth of the first wire routing portion 55 (notch) in the front-rear direction of the housing 1. It can be understood that more control wire harnesses are arranged in the second wire routing portion 56 and the third wire routing portion 57, so a larger depth is required. Since the first wire routing portion 55 is only used to arrange the motor wire 421 and the first ground wire 54, the depth of the first wire routing portion 55 can be smaller.

[0057] Optionally, as Figure 8 shown, the air inlet 121 is arranged on the lower end surface of the frame 12, the evaporator 2 protrudes in the direction of the air inlet 121, and the front wall surface of the frame 12 is open to form an air outlet 122. For example, in the projection plane orthogonal to the length direction of the base 11, the cross-section of the evaporator 2 is V-shaped, and the tip of the evaporator 2 is arranged towards the air inlet 121. It can be understood that the air flow entering the indoor unit of the air conditioner from the air inlet 121 below the frame 12 can exchange heat with the V-shaped wall surface of the evaporator 2, and the air flow after heat exchange can be discharged through the air outlet 122, thereby improving the heat exchange effect of the indoor unit of the air conditioner.

[0058] In the examples of the present application, since the air inlet 121 is provided on the lower end surface of the housing 12 and the front wall surface of the housing 12 is open to form the air outlet 122, the indoor unit of the air conditioner according to the embodiment of the present invention can be installed against the ceiling. It can be understood that since the air in the environment does not need to enter the interior of the indoor unit of the air conditioner from directly above the housing 12, the distance between the indoor unit of the air conditioner and the top wall (ceiling) of the room can be greatly reduced or eliminated, thereby improving the utilization rate of the indoor space. Especially for rooms with a relatively low height, the cramped feeling of the indoor space can be effectively reduced or eliminated. Therefore, the indoor unit of the air conditioner according to the embodiment of the present invention has very low requirements for the installation space, and the installation space only needs to be able to accommodate the indoor unit of the air conditioner, without leaving an air inlet space or an air outlet space above the indoor unit of the air conditioner, thereby expanding the applicable range of the indoor unit of the air conditioner.
