[0031] The present disclosure proposes an air conditioner indoor unit.

[0032] In an embodiment of the present disclosure, referring to FIG. 1 to FIG. 3, the indoor unit includes:

an electric control box (not shown);

a cleaning assembly 200 including: a cleaning module 210 configured to drive a filter screen to move on the filter screen rail module 220 to clean the filter screen. And including an electrical wire connecting end; and

an electrical wire A400 arranged on the cleaning module 210 and the filter screen rail module 220. And one end of the electrical wire A400 is connected to the electrical wire connecting end, and the other end of the electrical wire A400 is connected to the electric control box.



[0033] In this embodiment, it can be understood that the electric control box is configured with a circuit board therein, which is an important module for controlling the indoor unit. The cleaning assembly 200 is a assembly for driving and cleaning the filter screen. That is, the air is circulated in the process of operating the conditioner indoor unit circulates air. And the air needs to be filter screened through the filter screen after entering the indoor unit and before passing through the heat exchanger. After the indoor unit is used for a long time, the filter screen become dirty. So the cleaning of the filter screen is achieved by the cleaning assembly 200. The process of cleaning the filter screen 200 by the cleaning assembly 200 is as follows: firstly, the filter screen is driven to run in the cleaning assembly 200. And the cleaning of the filter screen is realized in the process of operation. The specific structure of the cleaning assembly 200 can be referred to other patent disclosures of the present applicant before the application date of the present disclosure. In order to achieve that the cleaning assembly 200 is controlled, it is necessary to connect the electric control box and the cleaning assembly 200 through the electrical wire A400 for transmitting electric power and/or signals.

[0034] For example, the cleaning module 210 is configured with a driving structure for driving the movement of the filter screen, a cleaning structure for cleaning the filter screen, a water pump, and a water cavity. The condensed water generated by the indoor unit is pumped by the water pump to the water cavity. And the movement of the filter screen is driven by the driving structure which cleaning the filter screen. The filter screen rail module is configured with a corresponding rail. And the filter screen can be moved in the rail. In general, The electrical wire A400 is required to connect with a water pump and a drive structure of the cleaning module 210. So the electrical wire A400 is divided into two sections. The first section A410 thereof is configured at the cleaning module 210 and the another section A420 thereof is configured at the filter screen rail module 220. That is, the electrical wire A400 is configured along the cleaning module 210 and the filter screen rail module 220 to avoid that the space of other electrical wires is occupied for the arrangement of the electrical wire A400 on the chassis of the indoor unit. And an overly messy situation with other electrical wires is avoided. Thereby the arrangement of the electrical wire A400 that connecting the cleaning assembly 200 is simplified.

[0035] In one embodiment of the present disclosure, referring to FIG. 3 to FIG. 5. the electrical wire A400 includes: a first electrical wire section A410 arranged at the cleaning module 210. And a second electrical wire section A420 arranged at the filter screen rail module 220; and

[0036] The first electrical wire section A410 is arranged along a height direction of the cleaning module 210. And/or the second electrical wire section A420 is arranged along a length direction of the filter screen rail module 220.

[0037] In this embodiment, in general, the cleaning module 210 and the filter screen rail module 220 are intersecting setting to fully utilize the internal space of the indoor unit. So that the first electrical wire section A410 is configured along the height direction of the cleaning module 210. The second electrical wire section A420 is configured along the length of the filter screen rail module 220, thus the length of the electrical wire A400 is minimized.

[0038] In an embodiment of the present disclosure, referring to FIG. 3 to FIG. 5. The electrical wire A400 includes: a first electrical wire section A410 arranged at the cleaning module 210. And a second electrical wire section A420 arranged at the filter screen rail module 220.

[0039] The first electrical wire section A410 is arranged at an outer side and a front side of the cleaning module 210. The indoor unit is hanged on a wall, and the front side of the cleaning module 210 is away from the wall. And the outer side of the cleaning module 210 is away from a heat exchanger of the indoor unit.

[0040] In the present embodiment, in order to realize the arrangement of the assemblys in the cleaning module 210. The portion of the first electrical wire section A410 is configured on the outer side of cleaning module. And the remaining portion thereof is configured on the front side of cleaning module. Thus, the setting of the assembly in the cleaning module 210 is facilitated. And the electrical wire A400 is also convenient for being integrally arranged. The side of the cleaning module 210 away from the wall is the front side thereof. The side thereof close to the wall is the rear side. And the side of the heat exchanger close to the indoor unit is the inner side. And the side of the heat exchanger away from the indoor unit is the outer side. In addition, the space corresponding to the front side of the cleaning module 210 is relatively abundant. And the front side space of the cleaning module 210 can be fully utilized.

[0041] Specifically, referring to FIG. 4 and FIG. 5, a first clamping line member 211 at the outer side of the cleaning module 210. And a second clamping line member 212 at the front side of the cleaning module 210. The first electrical wire section A410 is penetrated through the first clamping line member 211 and the second clamping line member 212. In the present embodiment, the first clamping line member 211 is a structure for forming a limit to the first electrical wire section A410. And thus the various forms can be taken. For example, a restriction form of other electrical wires in the indoor unit is taken. For the second clamping line member 212, the operation is the same as the first clamping line member 211. The first electrical wire section A410 is configured on the outer side and the front side of the cleaning module 210 by the arrangement of the first clamping line member 211 and the second clamping line member 212.

[0042] In an embodiment, referring to FIG. 4 and FIG. 5, the second clamping line member 212 is adjacent to the filter screen rail module 220, to force the first electrical wire section A410 and the second electrical wire section A420 to bend. In the present embodiment, by such an arrangement thereof, the first electrical wire section A410 and the second electrical wire section A420 are formed in a bend shape, and are corresponded to the joint of the cleaning module 210 and the filter screen rail module 220. And thus, the electrical wire A400 isn't in a state of suspension for coming off the cleaning assembly 200. Thereby the electrical wire A400 is prevented from being squeezed when assembling the indoor unit.

[0043] Specifically, referring to FIG. 4 and FIG. 5, the first clamping line member 211 defines a first through hole 2111, and the first electrical wire section A410 is penetrated through the first through hole 2111;
And/or, the second clamping line member 212 defines a second through hole 2121, and the first electrical wire section A410 is penetrated through the second through hole 2121.

[0044] In the present embodiment, the first clamping line member 211 is configured as a closed annular structure, and is configured with a first through hole 2111. So that the first through hole 2111 is passed through by the first electrical wire section A410. That is, the first clamping line member 211 is passed through by the first electrical wire section A410. The first electrical wire section A410 is confined within the first through hole 2111 to prevent offset. The same operation is true for the second clamping line member 212, and the details are not repeated herein. The first electrical wire section A410 is configured along the outer side and the front side of the cleaning module 210. And thus the first electrical wire section A410 is in a bent state. And the first electrical wire section A410 is prevented from detaching by the arrangement of the first clamping line member 211 and the second clamping line member 212.

[0045] Further, referring to FIG. 4 and FIG. 5, a third clamping line member 213 at the front side of the cleaning module 210, and the second clamping line member 212 and the third clamping line member 213 are arranged at intervals from top to bottom along a height direction of the cleaning module 210. And the first electrical wire section A410 is further penetrated through the third clamping line member 213. In the present embodiment, the third clamping line member 213 is a structure for forming a limit to the first electrical wire section A410. And thus various forms can be employed. For example, the height direction of the cleaning module 210 is exemplified by the state in which the indoor unit is suspended from the wall. The cleaning module 210 is configured with a certain height. Thus, the first electrical wire section A410 located on the front side of the cleaning module 210 is effectively fixed to prevent the first electrical wire section A410 from being partially suspended by configuring at intervals the second card portion 212 and the third card portion 213.

[0046] Specifically, referring to FIG. 4 and FIG. 5, the third clamping line member 213 defines an electrical wire penetrating cavity 2131 and an opening 2132 communicating with the electrical wire penetrating cavity 2131, and a portion of the first electrical wire section A410 is inserted into the electrical wire penetrating cavity 2131 through the opening 2132. In this embodiment, the third clamping line member 213 is not a closed annular structure and is configured with an electrical wire penetrating cavity 2131. A portion of the first electrical wire section A410 is inserted into the electrical wire penetrating cavity 2131 through the opening 2132. Such that the first electrical wire section A410 as a whole is in a state of passing through the third clamping line member 213. After the first electrical wire section A410 passes through the first clamping line member 211 or the second clamping line member 212, the portion of the first electrical wire section A410 is inserted into the third clamping line member 213. Thereby the assembly efficiency of the first electrical wire section A410 is improved. Moreover, since the first clamping line member 211 and the second clamping line member 212 have a closed annular structure, the first electrical wire section A410 is not easily separated from the first clamping line member 211 and the second clamping line member 212. The arrangement efficiency of the first electrical wire section A410 is improved on the premise of guaranting the fixing effect of the electrical wire section A410.

[0047] In an embodiment of the present disclosure, referring to FIG. 4 and FIG. 6. The electrical wire A400 includes: a first electrical wire section A410 arranged at the cleaning module 210. And a second electrical wire section A420 arranged at the filter screen rail module 220.

[0048] The second electrical wire section A420 is arranged at the front side of the filter screen rail module 220. The indoor unit is hanged on a wall. And the front side of the filter screen rail module 220 is away from the wall. In the present embodiment, as the portion of the first electrical wire section A410 is configured on the front side of the cleaning module 210, the utilization rate of space is also improved by the arrangement of the second electrical wire section A420 on the front side of the filter screen rail module 220. Thus the length of the electrical wire is minimized.

[0049] Specifically, referring to FIG. 6, a fourth clamping line member 221 at the front side of the filter screen rail module 220. And the second clamping line member A 420 is penetrated through the fourth clamping line member 221. The fourth clamping line member 221 is a structure for forming a limit to the second electrical wire section A420. And thus various forms can be employed. When the fourth electrical wire portion 221 is passed through the second electrical wire section A420, the second electrical wire section A420 is confined to the fourth electrical wire portion 221. Thereby the placement of the second electrical wire section A420 in the filter screen rail module 220 is achieved. With the arrangement of the first electrical wire section A410 and the above structure, the electrical wire A400 can be quickly configured in the cleaning assembly 200.

[0050] In an embodiment of the present disclosure, referring to FIG. 6, the fourth clamping line member 221 defines: a electrical wire penetrating groove 2213 arranged along a length direction of the filter screen rail module 220. And an opening 2214 communicating with the electrical wire penetrating groove 2213. Herein at least a part of the second electrical wire section A420 is inserted into the electrical wire penetrating groove 2213 through the opening 2214. In the present embodiment, the electrical wire penetrating groove 2213 is a space for accommodating the second electrical wire section A420. And the electrical wire penetrating groove 2213 is configured along the length direction of the filter screen rail module 220. So that the second electrical wire section A420 generally isn't configured with a bend. Thus, the second electrical wire section A420 is inserted into the electrical wire penetrating groove 2213 through the opening 2214. And the second electrical wire section A420 is in a state of passing through the fourth clamping line member 221. If the length of the electrical wire penetrating groove 2213 is long, the second electrical wire section A420 may be almost completely inserted into the electrical wire penetrating groove 2213. And the end of the second electrical wire section A420 is connected to the electric control box. If the length of the electrical wire penetrating groove 2213 is small, a portion of the second electrical wire sections A420 is inserted into the electrical wire penetrating groove.

[0051] Specifically, referring to FIG. 6, the fourth clamping line member 221 includes: a first limit element 2211, and a second limit element 2212. The number of the first limit element 2211 is at least two, and the two first limit elements 2211 and the second limit element 2212 are alternatively at intervals. The electrical wire penetrating groove 2213 and the electrical wire penetrating groove 2213 connected to the opening 2214 are defined between each first limit element 2211 and each second limit element 2212 and the electrical wire penetrating groove 2213 is connected to the opening 2214. And at least a part of the second electrical wire section A420 is inserted into the electrical wire penetrating groove 2213 through the opening 2214.

[0052] In an embodiment of the present disclosure, referring to FIG. 6. The second limit elements 2212 are arranged along the length direction of the filter screen rail module 220. And at least a part of the second electrical wire section A420 is supported by the second limit element 2212. In the present embodiment, the second electrical wire section A420 is configured with a tendency to fall downward under the action of gravity. And the second limit element 2212 is configured along the length direction of the filter screen rail module 220. That is, the second limit element 2212 is configured with a certain length. At least a portion of the second electrical wire section A420 is supported by the second limit element 2212. So that the arrangement of the second electrical wire section A420 is more stable.

[0053] In an embodiment of the present disclosure, referring to FIG. 1. The cleaning module 210 is connected to one end of the filter screen rail module 220, and the electrical control box is adjacent to another end of the filter screen rail module 220. In this embodiment, the cleaning module 210 is located at one end of the filter screen rail module 220. And the electrical control box is adjacent to another end of the filter screen rail module 220.
