DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner in which an electric box is mounted on a side surface of a main body.

[0002]

2. Description of the Related Art An air conditioner in which an electric box is mounted on a side surface of a main body is disclosed in, for example, Japanese Utility Model Publication No. 63-35320. The air conditioner described in this publication has a main body. An electrical box, which is installed in the ceiling space and houses electrical components for controlling devices such as a heat exchanger and a blower in the main body, is attached to a side surface.

[0003]

The air conditioner described above has a configuration in which a slide plate provided above the electrical box must be inserted into a guide extending upward from the lower end of the side surface of the main body, and then the electrical box is attached. Was. In an air conditioner in which the main body is placed in a ceiling space, the upper portion of the electrical box is located at a considerably high position and the positional relationship is difficult to understand, so that it is difficult to attach the electrical box to the main body.

[0004] The present invention provides an air conditioner in which an electric box is easily attached to a side surface of a main body.

[0005]

SUMMARY OF THE INVENTION The present invention relates to an air conditioner comprising a main body having a built-in heat exchanger and a blower, and an electric equipment box arranged on a side surface of the main body and containing electric components. The side of the electrical box is provided with a temporary fixing device having a support portion that is applied to the side surface of the electrical box and is in surface contact with the electrical box and a support portion that regulates the rotation of the electrical box to perform positioning of the electrical box. is there.

[0006]

[Function] In this air conditioner, since the temporary fixing device is provided on the side surface of the main body, the temporary fixing device hits the side surface of the electric equipment box, so that it is easy to confirm the positional relationship between the temporary fixing device and the electric equipment box. Is easy to temporarily fix with a temporary fixing tool.

[0007]

An embodiment of the present invention will be described with reference to the drawings.

1 and 2, reference numeral 1 denotes an air conditioner, which comprises a main body 2 suspended in a ceiling space and a decorative panel (not shown) attached to a lower portion of the main body.

Reference numeral 3 denotes a fan motor for driving a cross-flow fan (not shown), 4 denotes a drain pan for receiving drain from a heat exchanger (not shown), 5 denotes an electrical box containing electric parts, and 6 denotes a control box. A metal temporary fixing tool that is applied to the electric box to position the electric box. The temporary fixing tool is attached to the side surface of the main body 2.

[0010] In FIG.
A supporting portion (see oblique lines) 6a which comes into surface contact with the surface is formed. Reference numeral 6b denotes a support integrally formed with the temporary fixing tool 6, and the support is provided close to the right side of the electrical box 5. Since the center of gravity of the electrical box 5 is deviated to the right, when the holding portion 6a is weakly pressed, the right side of the electrical box 5 is lowered, but the right side of the electrical box 5 hits the support portion 6b. The box 5 does not fall off before being screwed. Also, the presser on the left side of the support 6a is weak,
When the left side of the electrical box 5 is lowered, the right side of the electrical box 5 hits the support 6b, so that the electrical box 5 does not fall off before being screwed due to friction. Reference numeral 6c denotes a tip of the temporary fixing tool 6, which has a shape which is expanded to the side to make it easy to insert the electrical box 5. 7 is an electrical box 6
This is a screw for attaching to the body.

In FIG. 4, the electrical box 5 comprises a lid 5a, a main box 5b and an auxiliary box 5c located at the lower part.

In FIG. 5, reference numeral 8 denotes a main printed circuit board (electric parts) for controlling a cooling or heating operation and for transmitting and receiving signals to and from an outdoor unit, and 9 for controlling a heat exchanger and a blower for a dry operation. Printed circuit board [electric parts], 10
Is a printed circuit board [electrical component] for controlling the fan motor 3 using a DC motor, 11 is a noise filter substrate [electrical component], and 12 is attached to the lid 5a. 13 is a polypropylene rail which is attached to the main box 6b and the auxiliary box 5c and sandwiches the substrates 8, 9, 10; 14 is a terminal plate; 15 is a terminal attached to this terminal plate; 16 is another component. 17 is a receiving device provided with a receiver 17a, 18 is a temperature sensor 18a and a humidity sensor 1
8b is attached to the lower part of the electrical box 5 with a sensor mounting tool,
Reference numeral 19 denotes a display attached to the main housing, which is substantially the same as that shown in FIG. 4, so that a service person can understand how to disassemble the electrical box 5.

FIG. 6 shows an upper part of the main box 5b and the auxiliary box 5c. The hook 5d is formed on the upper part of the auxiliary box. Bent. Then, the hook piece is hooked on the hook 5e formed on the upper part of the main box 5b. The hook 5 is attached to the hook 5e.
If the main box 5b and the auxiliary box 5c do not come off when the screws 5f stop after hooking d. Next, cover 5a is screwed
g to the main box 5b and the auxiliary box 5c.
Is completed.

Since the electrical box 5 is composed of the main box 5b and the auxiliary box 5c, the main box 5b and the auxiliary box 5c have a substantially U-shaped cross section, and the box is easily pushed and expanded by hand. It is also possible to take out the substrates 8, 9 from the sides of the box. In addition, the deformation due to the expansion is returned to the original shape by stopping the screws 5f and 5g.

Further, only the lid 5g is removed by removing the screw 5g, and without removing the electrical box 5 from the main body 2, the substrate 8,
Maintenance of 9, 10, and 11 can also be performed.

In the air conditioner 1 configured as described above, since the temporary fixing tool 6 is provided on the side surface of the main body 2, the temporary fixing tool 6 comes into contact with the side surface of the electrical box 5, and the temporary fixing tool 6 and the electrical
It is easy to confirm the positional relationship from the side from the side, and it is easy to temporarily fix the electrical component box 5 with the temporary fixing tool 6. At this time, since the temporary fixing tool 6 is formed with the expanded distal end portion 6c, the electrical component box 5 can be easily inserted between the temporary fixing tool 6 and the main body 2. In addition, after the temporary fixing, even if the holding portion 5a is weakly pressed, the support tool 5b supports the electrical box 5 so as not to fall down, so that the screw 7 between the main body 2 and the electrical box 5 is fixed with a short time. Electrical box 5
Does not fall from the main body 2. Since the temporary fixing device 6 is provided on the side surface of the main body 2, and since the temporary fixing device 6 is configured to press the side surface of the electrical box, the present invention can be applied to a conventional air conditioner without the temporary fixing device 6. is there.

[0017]

According to the present invention, there is provided an air conditioner including a main body having a built-in heat exchanger and a blower, and an electric equipment box arranged on a side surface of the main body and containing electric components. Since the positioning of the electrical box is performed by providing a temporary fixing device having a support portion which is applied to the side surface of the electrical box and is in surface contact with the electrical device box and a support portion which regulates the rotation of the electrical device box, the temporary fixing device includes: It is easy to recognize the positional relationship with the electrical box,
Since the electrical box is easily temporarily fixed with the temporary fasteners, the electrical box can be easily attached to the side surface of the air conditioner.
