In the prior art, the load lines such as the power line and the signal line of the indoor unit of the air conditioner are synchronously routed with the connecting pipe, and then bundled together and fixed at a certain position of the internal machine of the air conditioner. This design has the following drawbacks:

First of all, when the evaporator is cleaned and disassembled, the internal and external connecting pipes are affected by load lines such as power lines and signal lines, which is extremely inconvenient for disassembly and increases the disassembly work. Secondly, when the evaporator is cleaned and disassembled, since the power line and the signal line are both charged bodies, there is a hidden danger to the maintenance and cleaning personnel.

Again, the traces are cluttered and the traces are not standardized, which can cause interference between the load lines. In addition, in the final assembly production and the post-maintenance inspection, various load lines are staggered, and it is necessary to clarify the walking of various load lines, and the workload is large, which is not conducive to the improvement of production efficiency. The wire is not fixed firmly, and the transmission line and the casing are subjected to transmission vibration, so that the air conditioner may have a noise problem during use.

1 to 3 illustrate an embodiment of an air conditioner indoor unit provided by the present invention.

The air conditioner indoor unit includes a casing in which an evaporator 1 for exchanging heat is disposed, and the evaporator 1 is connected to the air conditioner outdoor unit through a connection pipe 2.

The air conditioner indoor unit is installed on the air conditioner installation wall surface when in use. The housing includes a base 3 that is mounted close to the mounting wall. The base 3 is provided with a routing structure toward the side on which the wall is mounted. The routing structure includes a wire trough respectively set corresponding to the load line type of the air conditioner indoor unit. The wire trough is composed of a plurality of ribs 5 on the base 3, and the ribs 5 extend in the same direction as the wire troughs extend. The wire trough includes opposite first and second sides, and the first side and/or the second side are provided with snap protrusions extending toward the other side near the top end, and the snap protrusions are the wire buckles 4. The wire buckle 4 and the wire trough are collectively referred to as a wire structure. The load line types include a signal line 6, a power line 8, and a rubber cord 7, respectively, and each of the load lines corresponds to one of the wire grooves, thereby facilitating installation and routing. The wire trough and the wire buckle 4 are collectively referred to as a wire structure.

When the air conditioner is normally installed on the indoor installation wall surface, the wiring structure on the base 3 is close to the installation wall surface, and the fixing clearance between the base 3 and the installation wall surface is small, and the base 3 and the installation wall surface are In the cooperation, the signal line 6, the power line 8, and the rubber cord 7 are enclosed in a small space, thereby preventing the damage of the insects to the line and avoiding such safety hazards.

The connecting pipe 2 is disposed on the other side of the base 3 and is fixed in the casing.

In the technical solution, the load lines of the power line 8, the rubber cord 7, and the signal line 6 are separately routed in the indoor unit of the air conditioner, the connecting tube 2 is separately routed, and the load line and the connecting tube 2 are separately arranged. In this way, firstly, the internal wiring of the modular air conditioner is more standardized; secondly, the convenience of cleaning and disassembling the whole machine is improved, and the influence of the line body is hindered when the connecting pipe 2 is disassembled in the prior art, so that evaporation is performed. The device 1 can be easily removed for cleaning without being affected by the line body.

As another implementation manner of the wire trough, the wire trough may be a groove structure formed on the base 3.

As another implementation manner of the wire structure, the opening of the wire trough is covered with a card board, which is a plate-like structure extending along the wire trough and set to a length, and the card board is a wire buckle 4. A cable slot for the card slot is provided on both sides of the cable trough. The cable trough is also provided with a card buckle for fixing the card board.

The installation position of the load line and the connecting pipe 2 are not limited to the inner and outer sides of the base 3, and the two are separately arranged.

The wiring structure can be mounted on the base 3 or can be integrally formed with the base 3.

In this embodiment, the cable structure is designed according to the maximum number of wires, that is, when the air conditioner is powered by the internal machine and is a fixed frequency machine, the load line types include the signal line 6, the power line 8 and the rubber sheath cable respectively. 7. When the external power supply of the inverter is powered, the air conditioner indoor unit does not include the power cord 8. At this time, the wiring structure can be set only for the signal line 6 and the rubber sheathed cord 7. Obviously, the actual number of traces and the number of trace structures can be determined according to the actual situation of each model. Each load line has a corresponding trace structure, and the trace structure and the load line type may not strictly correspond.

The wiring structure is set so that the load line of the indoor unit of the air conditioner is routed according to the designed routing structure, and the routing is more standardized and rationalized. It avoids possible interference, greatly improves assembly efficiency and post-maintenance efficiency, and has higher safety for workers. Moreover, the load line is prevented from being unreliable, and the transmission line and the housing are subjected to transmission vibration, so that the air conditioner may have a noise problem during use.

It is apparent that the above-described embodiments are merely illustrative of the examples, and are not intended to limit the embodiments. Other variations or modifications of the various forms may be made by those skilled in the art in light of the above description. There is no need and no way to exhaust all of the implementations. Obvious changes or variations resulting therefrom are still within the scope of the invention.
