DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner whose main body is housed in a ceiling space of a house.

[0002]

2. Description of the Related Art Conventionally, the structure of an air conditioner housed in a ceiling space of a house is shown in Japanese Utility Model Laid-Open Publication No.
No. 1 publication.

[0003] The air conditioner disclosed in this publication comprises a main body and an electrical box which is detachably attached to a side surface of the main body. The main body contains a heat exchanger and a blower, and the electrical box contains electrical components for controlling the operation of the blower and the like.

[0004] The electrical box can be removed from the main body, so that service inspection of electrical components can be performed without moving the main body.

[0005]

In such an electrical box, all electrical components such as a transformer, a capacitor, a printed circuit board, and a terminal board are housed. Therefore, the electrical box is inevitably large, and the electrical box may occupy almost the entire side surface of the main body. Therefore, the connection port and the drain outlet of the refrigerant pipe led out of the main body are arranged on a surface different from this side surface, and it is necessary to secure a large service space around the main body.

Although the transformer and the capacitor do not require much service inspection as compared with the printed circuit board and the terminal board, if the transformer and the capacitor are housed in the electrical box in the same state as the printed circuit board and the terminal board. In addition, there is a possibility that the service of the printed circuit board and the terminal board becomes difficult to be performed by the transformer and the capacitor.

SUMMARY OF THE INVENTION It is an object of the present invention to facilitate a service check of a main body of an air conditioner housed in a ceiling space.

[0008]

In order to achieve the above object, the present invention provides a heat exchanger, a main body having a built-in blower and housed in a ceiling space of a house, and an electric component mounted on a side surface of the main body. In the air conditioner provided with an electric box that houses therein, the electric box is composed of a front part having a large opening area and an overhanging part formed so as to be connected to the rear of the front part and having a small opening area. The parts that require a lot of service inspection are stored in the overhang, and the parts that do not require a lot of service inspection are stored in the overhang.Only this overhang is inserted and fixed in the opening provided on the side of the main unit. The front part is exposed from the side of the main body.

[0009]

The electrical box can be positioned by inserting the overhang of the electrical box into the opening on the side surface. In addition, by storing components that do not require relatively large service inspections, such as capacitors and transformers, in the overhang, printed circuit boards and terminal boards that require many service inspections are located on the front side.

[0010]

FIG. 2 is an explanatory view showing a state in which the air conditioner of the present invention is embedded in a ceiling space in a room. Reference numeral 1 denotes a main body in which a heat exchanger and a blower are housed. It is stored in the ceiling space 3. Reference numeral 4 denotes an electrical box attached to the side surface 5 of the main body 1. The side face 5 is provided with a connection port 6 for a refrigerant pipe and a service panel 7. By removing the service panel 7, a service check of the drain pump (not shown) stored in the main body 1 can be performed from outside the main body 1.
Reference numeral 8 denotes a suction member attached to a ceiling plate 9, which is connected to a suction side surface 11 of the main body 1 via a suction duct 10.
A blowing member 12 is suspended by the suspending device 2 and attached to the ceiling plate 9, and is connected to the discharge port 14 of the main body 1 via a blowing duct 13. These devices constitute an air conditioner.

Reference numeral 15 denotes a maintenance panel provided on the ceiling plate 9, which is detached during service inspection of the main body 1 so that an operator can enter the ceiling space. The maintenance panel 15 is provided nearby (for convenience of explanation, the maintenance panel 15 is shown in the corner of the room in FIG. 1).

FIG. 1 is a perspective view of the main body 1, and FIG. In FIGS. 1 and 3,
Reference numeral 16 denotes an L-shaped angle provided on the side surface. A hanging tool (bolt) 2 is inserted into a hole 17 of the angle, and a nut (not shown) is screwed to a tip of the hanging tool. Reference numeral 18 denotes an opening provided on the side surface 5. 19 is a main drain outlet, and 20 is an auxiliary drain outlet.

Here, the electrical box 4 has a two-stage external appearance, and the overhang 21 is formed by the housing 2 of the electrical box 4.
It is smaller than 2. The vertical dimension a of this overhang 21
The horizontal dimension b substantially matches the vertical dimension a and the horizontal dimension b of the opening 18. Therefore, the overhang portion 21 of the electrical component box 4 is housed in the opening 18 of the main body 1 (see the dashed line arrow).
Then, the mounting piece 23 of the electrical box 4 and the right side surface 24 of the housing 22 are applied to the side surface 5 of the main body 1 to close the opening 18. The hole 25 of the mounting piece 23 is aligned with the hole 26 provided on the side surface 5 of the main body 1 and fixed with screws. A sealing material (illustrated) is adhered to the side surface 5. Therefore, when the electrical box 4 is attached to the side surface 5, the opening 18 of the side surface 5 is opened.
Is securely sealed by the electrical box 4.

Reference numeral 27 denotes a capacitor housed in the right side of the electrical box 4, and reference numerals 28 and 29 denote terminal boards and printed boards arranged in the housing 22 of the electrical box 4. Particularly, the mounting piece 30 of the printed board 29 Fixed piece 31 in front of housing 22
Attached to. As a result, the overhang portion 21 in which the capacitor 27 and the like are stored is covered by the printed circuit board 29.

As described above, the terminal board 28 and the printed circuit board 29 which require more service inspection than the capacitor 27 and the like are placed on the near side (front part) in the electrical box 4, and the capacitor 27 and the like which do not require much service inspection. Are arranged on the back side (overhang portion) of the electrical box 4 to facilitate service inspection. Here, as is clear from FIG. 1, the front side (front part) of the electrical component box has a larger opening area than the back side (projection part). And only this overhang is the side surface 5 of the main body 1.
The front of the electrical component box 4 is exposed from the side surface 5 of the main body 1. 3
Reference numeral 2 denotes an opening provided in the left bottom plate of the electrical box 4, and a terminal board 28
And the like are connected to the power supply line. 33 is an electric cover,
The upper end 34 is inserted into the upper groove 35 of the electrical box 4, and the lower end 36 is screwed to the lower part on the left side.

As described above, since the inside of the electrical box 4 externally attached to the main body 1 is substantially in a two-tiered state, the depth dimension is increased and the vertical and horizontal dimensions are suppressed, so that the electrical box 4 is mounted. The service panel 7 on the side 5 of the main body 1
The two drain outlets 19 and 20 and the connection port 6 of the refrigerant pipe can be arranged, and the service inspection of the main body 1 can be performed at one place (one side).

[0017]

As described above, the electrical box is composed of a front part having a large opening area and an overhanging part formed to be connected to the rear of the front part and having a small opening area. Parts that require a lot of inspection are stored in the overhang, and parts that do not require a lot of service inspection are stored in the overhang.Only this overhang is inserted and fixed in the opening provided on the side of the main body.
Since the front part of the electrical box is exposed from the side surface of the main body, the size of the electrical box can be reduced, and the installation space on the side surface of the main body of the electrical box can be reduced. In addition, by reducing the installation space for the electrical box, it is possible to arrange the hanging brackets and other parts of the main body on this side surface, thereby facilitating service inspection of the main body. On the other hand, also in the electrical box, components requiring many service checks are arranged at the front part thereof, so that the service check of the electrical components can be easily performed.
