Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a wall-mounted air conditioner whose main body casing is made of plastic.
Specifically, the present invention relates to an air conditioner in which a motor is housed inside the main body casing, and a lead wire led out from a sheet metal electrical component box is connected to the motor.

(Prior Art) Conventionally, this type of air conditioner has, for example,
There was something like the one shown in Utility Model Publication No. 58-15773. FIG. 5 shows a part of the conventional example, in which a motor 22, a heat exchanger 23, various piping for heat exchange, an electric control mechanism, etc. are incorporated inside a main body case 21 made of plastic, and a sheet metal The lead wire 25a led out from the electrical parts box 24 made by the manufacturer is connected to the lead wire 25b led out from the motor 22.
is connected to via a connector 26.

(Problems to be Solved by the Invention) By the way, a high voltage current of 100 V or more is often applied to the lead wire 25 for driving the motor, and the lead wire 25 may generate heat to a considerably high temperature. In this case, since the lead wire 25 is set to be relatively long with enough room for assembly, it may protrude outside the electrical component box 24 and be assembled close to the main body casing 21.
If the lead wire 25 generates heat to a high temperature in such a state and the main body casing 21 is heated for a long time, there is a risk of thermal deformation, thermal discoloration, or damage due to thermal embrittlement.

Of course, a solution to this problem could easily be to cover the exposed lead wire with a flexible metal tube (conduit), but such a solution would require that the lead to the metal tube The drawback is that it is troublesome to insert the wires, especially since it is necessary to insert the lead wires before attaching the connector, which limits the assembly procedure and makes it difficult to handle the lead wires with the metal tube pre-assembled. There were practical difficulties.

The present invention was developed in view of these circumstances, and by making it possible to easily cover the lead wires without any restrictions on the assembly procedure, it is possible to cover the lead wires easily without compromising the ease of assembly. The purpose is to make it possible to configure a highly safe air conditioner.

(Means for solving the problem) In order to achieve this purpose, the present invention
A motor 6 is installed in a plastic main casing 1.
In an air conditioner in which a lead wire 8 led out from an electrical parts box 7 is connected to the motor 6, one side of the electrical parts box 7 is located near the lead wire lead-out part 6a of the motor 6. At the same time, the electrical component box 7 is divided into two parts so that a dividing line exists on one side of the electrical component box 7, and one split box part 7a is fixed to the attached part 7c on the main body casing 1 side. With,
The other divided box part 7b is pivotally supported and attached so as to be freely openable and closable, and the notch recess 11 through which the lead wire 8 is inserted is attached to at least the fixed side divided box part 7.
It is formed on the dividing edge 10 on one side of the motor 6 side of a.

(Function) According to this configuration, after the lead wire is wired and connected with the other split box part on the opening/closing side open, the lead wire is inserted into the notch recess formed in the split edge of the split box part on the one fixed side. The lead wires can be covered by the electrical component box by inserting and positioning the lead wires and fixing the opening/closing side divided box portions in the closed position.

The other divided box portion 7b is pivotally supported by the attached portion 7c on the main body casing 1 side and is provided so as to be openable and closable, so that it is held by the attached portion 7c when opened.

(Example) Next, the present invention will be described in detail based on an example shown in the drawings. FIG. 4 schematically shows a wall-mounted air conditioner according to an embodiment of the present invention, in which an intake grille 2 is provided at the upper front of a main body casing 1 as a plastic molded product, and an outlet grille 3 is provided at the lower part of the main body casing 1. is provided. Inside the main body casing 1, a heat exchanger 4 is disposed opposite the intake grille 2.
A fan 5 is horizontally suspended at the lower back part of the fan 5, and a motor 6 is directly connected to the right end of the fan 5.Although not shown, a main body casing 1
Inside, various piping for heat exchange and electrical control mechanisms are installed.

As shown in Fig. 1, the upper part of the motor 6 is equipped with an electrical component box 7 made of sheet metal, and inside this is a terminal board A for introducing power from the outside, a printed circuit board, a relay, etc. Control parts are incorporated.
A lead wire 8 led out from this electrical component box 7 is connected to the motor 6.

As shown in FIGS. 2 and 3, the electrical component box 7 is structured in such a way that it is divided into two parts in the front and back, and the rear divided box part 7a is attached to the base wall 7c as an attached part on the main body casing 1 side. The front divided box portion 7b is fixed to the base wall 7c.
It is attached so that it can swing open and close around the vertical axis P,
In the closed state, the opening/closing side divided box portion 7b can be fixed by screwing on the upper side while abutting against the fixed side divided box portion 7a.

A connector 9 is attached to the surface of the opening/closing side divided box part 7a facing the fixed side divided box part 7b in the closed state, and a connector 9 connected to one end side of the lead wire 8 is coupled to this connector 9. has been done.

The lower surface of the electrical component box 7 is close to the upper part of the lead wire lead-out portion 6a of the motor 6, and a notch recess 11 through which the lead wire 8 is inserted is formed in the split edge 10 of the fixed side split box portion 7a. When the divided box portion 7b is open, the notch recess 1 is opened.
When the split box part 7b is closed, the entire lead wire 8 on the motor 6 side is covered by the electrical parts box 7, and the cutout recess 11 is inserted into the opening/closing side split box part. The lower end portion 12 of the lower end portion 7b is closed to prevent movement of the lead wire 8 inserted therein.

In FIG. 3, reference numeral 13 denotes an insertion hole for internal and external communication wiring and a power cord.

According to the present invention, a recess opposite to the cutout recess 11 may also be formed at the lower end 12 of the opening/closing side divided box portion 7b. Further, the divided box portion 7b is not limited to the above-mentioned swinging opening/closing type, but may be configured to open/close when attached or removed, for example.

Further, in the above embodiment, both the divided box parts 7a and 7b are provided on the base wall 7c, but the base wall 7c may be integrally extended from the fixed side divided box part 7a.

(Effects of the invention) As described above, according to the invention, the electrical component box itself, which can be opened and closed, covers almost the entire lead wire, so there is no need for a special cover member to cover the lead wire. The heat generated by the lead wires no longer affects the main body casing, improving the safety of the air conditioner.

Moreover, wiring connection work for lead wires inside the electrical parts box can be easily done with the split box part on the opening/closing side open. Since it is supported by a shaft, there is no need to remove it one by one when releasing it and wiring it. Moreover, after completing the wiring connection, the lead wire is inserted into the notch recess formed on the dividing edge between the two divided box parts, positioned, and the lead wire is inserted into the notch recess by closing the divided box part. Since the lead wire can be held, it is now possible to easily prevent the lead wire from coming off and safely hold the lead wire in a predetermined position.
