The positioning post 321 is inserted into the positioning slot 3011, so that the first support post 31 and the second support post 32 are buckled together, and the support post 3 is formed. In this example, the connection wire of the electric heating device 10 may be placed into the first wire outlet hole 301 from the positioning groove 3011, and then the first support post 31 and the second support post 32 are buckled together, so as to implement routing arrangement of the connection wire passing through the first wire outlet hole 301, which has a technical effect of facilitating routing of the connection wire. In addition, the positioning post 321 also has a technical effect of encapsulating the connection wire in the first wire outlet hole 301, and prevents the connection wire from being separated from the first wire outlet hole 301.
Further, as shown in fig. 9 and 10, in the foregoing example in which the second wire outlet hole 20 is provided in the first bracket 21 and the second bracket 22, the third half hole 201 is provided in the first bracket 21, and the fourth half hole 202 is provided in the second bracket 22. The third half hole 201 is mated with the fourth half hole 202 to form the aforementioned second wire outlet hole 20. In this example, the connection wire of the electric heating device 10 may be placed from the third half hole 201 or the fourth half hole 202, and then the first bracket 21 and the second bracket 22 are buckled together, so as to implement the routing arrangement of the connection wire passing through the second wire outlet hole 20, which has the technical effect of facilitating the routing of the connection wire.

The second bracket 22 is provided with a positioning convex hull 222 which is matched with the positioning clamping groove 213. The positioning convex hull 222 is inserted into the positioning clamping groove 213 to position the first bracket 21 and the second bracket 22 in an assembling manner, so that the assembling precision of the first bracket 21 and the second bracket 22 is improved.
Embodiments of the present invention also provide an air conditioner, which may include the indoor unit in any of the above examples.
In the above embodiment, the air conditioner provided by the present invention has the advantages of preventing air leakage and improving the electrical safety of the motor heating device due to the arrangement of the indoor unit.
The working principle and preferred embodiments of the present invention are described below.
The invention solves the following technical problems: 1. the electric heating device 10 is conveniently arranged in a wiring mode; 2. good sealing of the right side of a heat exchanger such as an evaporator; 3. the manner of assembly of the right side of the electric heating device 10 with the evaporator side plate 11 is changed.
The technical scheme of the invention has the following points: the connecting wire of the electric heating device 10 is routed from the support column 3 through a simple routing structure, a certain fixing effect is achieved on the connecting wire of the electric heating device 10 such as a power wire, the abdicating part of the side plate 11 is eliminated, and the tightness of the side plate 11 to the right side of the evaporator is ensured. The assembly gap between the side plate 11 and the support column 3 is winded through the windbreak ribs 4, so that air leakage on the right side of the evaporator is well prevented, the problem of condensation at the position is solved, and the electrical safety of the electric heating device 10 is ensured. The positioning bolts 5 on the bracket 2 are directly hung on the side plates 11, so that the assembly action is simple, the production efficiency is greatly improved, and the assembly working hours are reduced.
The specific implementation method is shown in the figure:
the bracket 2 is composed of 2 parts: a first bracket 21 (fig. 9) and a second bracket 22 (fig. 10). The first bracket 21 and the second bracket 22 constitute a main body portion of the right bracket 2 of the electric heating device 10. The first bracket 21 and the second bracket 22 are fixed to the right end of the electric heating device 10 by screws. Both the first bracket 21 and the second bracket 22 are mounted in place by a locating boss 222 on the second bracket 22.
As shown in fig. 9, the first bracket 21 is provided with an electric heating temperature limiter mounting position 211 and an electric heating fuse body mounting position 212, and the two elements, i.e., the electric heating temperature limiter and the electric heating fuse body, are connected to the electric heating device 10 through the second wire outlet 20 shown in the drawing.
As shown in fig. 10, the second bracket 22 is provided with a mounting groove 221 for mounting the tube body of the electric heating device 10. The second bracket 22 is fixed to the electric heating device 10 by screws. The right side of the second bracket 22 is provided with a positioning post 321 of the first wire outlet 301. The positioning post 321 can serve to position the first bracket 21; and can also function to block the connection wire of the electric heating device 10 from coming out. The connection lines of the electric heating device 10, such as the connection lines of the power supply line and the electrical box, are drawn out of the support column 3 through the illustrated first wire outlet 301. After the connection wires are well arranged, the connection wires are wound into the second wire outlet holes 20 through the wire routing gaps 311 on the support columns 3, and the connection wires of the electric heating device 10 are fixed. Finally, the electric heating device 10 is directly inserted into the side plate 11 of the evaporator for fixing through the positioning bolt 5 on the bracket 2, and compared with the traditional installation mode through an electric heating support column, the installation mode of the positioning bolt 5 omits troublesome rotation alignment, and the positioning bolt 5 is directly inserted into the side plate 11 from right to left.
Through the illustrated wire outlet structure, the connecting wires of the electric heating device 10 can be led out of the through holes 101 of the side plates 11 through the support columns 3, and no extra abdication is needed. Since the side plate 11 does not need to be shifted for the connection line of the electric heating device 10, the gap above the side plate 11 only remains a small wiring gap of the first wire outlet 301 and an assembly gap between the via hole 101 and the support column 3 above the side plate 11.
