[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an indoor unit of an air conditioner in which a refrigerant distribution, terminal plates and the like are housed in a housing.

[0002]

2. Description of the Related Art Conventionally, as an indoor unit of this type of air conditioner, there is one as shown in Japanese Utility Model Publication No. Sho 62-31791.

[0003] The air conditioner disclosed in this publication has a refrigerant pipe and a terminal board for connecting a heat exchanger between the room and the outside in a housing, and a thin groove is formed at a lower portion of the housing. I have. Then, if necessary, a part of the housing is cut off at the groove portion, thereby forming a hole for removing the refrigerant pipe.

[0004]

The indoor unit of such an air conditioner has the following disadvantages. If a worker fails to work when the part of the housing is cut off or the housing is cracked and the housing is severely separated or damaged more than necessary, replace the large housing or replace the entire indoor unit. I had to. In addition, chips may enter the indoor unit during the operation. In order to prevent the above drawbacks, the operator must carefully perform the separating operation, which takes a lot of trouble.

[0005] The present invention is intended to reduce the labor required for forming a hole for removing a refrigerant pipe.

[0006]

In order to solve the above-mentioned problems, the present invention incorporates an indoor heat exchanger, an electrical component, and a terminal board to which leads of the electrical component are connected in a housing. In an indoor unit of an air conditioner in which a service cover that covers the housing is detachably attached to the housing, the service cover is provided with a pipe outlet for guiding a refrigerant pipe extending from the indoor heat exchanger to the outside of the housing. A rib is provided around the pipe outlet.

[0007]

When guiding the refrigerant pipe out of the housing, first remove the service lid from the housing, hold the removed service lid in a hand, and cut out the pipe outlet to form the pipe outlet and form the pipe outlet. The ribs remain around the pipe outlet. Then, the service lid in the notched state is attached to the main body.

1 shows an indoor unit of an air conditioner according to the present invention. Reference numeral 1 denotes an indoor unit, on the rear surface 2 of which an indoor wall surface is installed. Reference numeral 3 denotes a suction grill formed at an upper portion of the main body of the heat exchange unit, and reference numeral 4 denotes a discharge port formed at a lower portion of the main body. The discharge port is provided with a wind direction changing blade 5. Reference numeral 6 denotes a plate fin type heat exchanger built in the main body.

Reference numeral 7 denotes an electrical box arranged on the right side of the heat exchanger 6 and has an open front. Although not shown, electrical components are stored inside the transmission box. Reference numeral 8 denotes a display plate mounted on both right and left edges 9 and 10 of the electrical box 7 and provided with a lamp (not shown). Reference numeral 11 denotes a terminal board attached to a lower portion of the transmission box 7. An insertion port 12 and a ground screw 13 are provided on the lower surface of the terminal board. A wiring cord (not shown) between the units from the outdoor heat exchange unit is inserted into the insertion port 12, and a ground wire (not shown) from the outdoor unit is attached to the mounting screw 13. The lead wire 14 connected to the terminal board 11 is connected to the electrical equipment 8 through the opening 15 of the electrical equipment box 7.
Is guided inside.

Reference numeral 16 denotes a service cover for covering the terminal board 11, which is made of resin.
7 is detachably attached. When installing the indoor unit, the service cover 16 is removed and the indoor unit 1 is removed.
From the lower part of the terminal board 11
Connect to Needless to say, the terminal cover 11 is covered with the service cover 16 after the wiring cords and the ground wires between the units are connected to the terminal board 11.

FIG. 2 shows a perspective view of the service lid. The service lid 16 includes a portion 18 covering the terminal board 11 and the refrigerant pipe 1.
9 is formed. Further, ribs 21, 22, and 23 are formed in a U shape inside the service lid 16, and grooves 24 and 25 are formed inside the ribs 21, 22, and 23. Of these grooves, the groove 25 on the side of the rib 22 is formed deeper than the other grooves 24 and the groove (not shown) inside the rib 23. When the refrigerant pipe 19 is arranged so as to extend to the lower part of the indoor unit 1, the portion surrounded by the U-shape by the ribs 21, 22 and 23 may be separated from the service lid 16. In this case, first, the service lid 16 is cut along the groove 24 of the service lid 16 and the groove inside the rib 23 and is bent at the groove 25, whereby the service lid 16 is easily broken along the groove 25, and the ribs 21, 22, 23 The part enclosed by can be easily cut out. In this manner, the service lid 16 in which the portion 20 of the service lid 16 has been cut away, that is, the service lid 16 in which the pipe outlet 20 has been opened, is attached to the indoor unit 1, and thereafter, from the pipe outlet 20, as indicated by the dashed line in FIG. As shown, the refrigerant pipe 19 is guided to the outside of the indoor unit. The service outlet 16 has a pipe outlet 2
The operation of forming 0 can be performed while the indoor unit 1 is still attached to the indoor wall surface.

As described above, in the present invention, the pipe outlet 20 of the refrigerant pipe 19 can be easily formed on the service lid 16. Further, since the rib having a U-shaped groove is formed on the service lid, the groove or the rib serves as a guide to facilitate cutting, and the refrigerant pipe take-out portion can be easily formed on the service lid.

In addition, in the embodiment of the present invention, since the U-shaped rib of the service lid is formed, the rib remains around the hole after the refrigerant pipe outlet is formed in the service lid. Ribs are reinforcements for the service lid.

In the present invention, a passage having a size through which the refrigerant pipe is passed is formed easily, or processing is performed using ribs or grooves formed on the back surface of the service lid so that the appearance is not unsightly. May be formed by notches or holes.

[0015]

[Effects of the Invention] As described above, the indoor unit of the air conditioner of the present invention incorporates an indoor heat exchanger, an electrical component, and a terminal board to which a lead wire of the electrical component is connected in a housing. In an indoor unit of an air conditioner in which a service cover for covering a panel is detachably attached to the housing, the service cover has a pipe outlet for guiding a refrigerant pipe extending from the indoor heat exchanger to the outside of the housing. Since the ribs are provided around the pipe taking-out part and the service cover is removed from the indoor unit (housing), the work of forming the pipe taking-out part can be performed, and the pipe taking-out work can be easily performed. Further, compared to a conventional indoor unit in which a part of a large indoor unit is separated to form a pipe outlet, the installation operation of the indoor unit itself can be simplified. In addition, when the pipe outlet is cut off, a rib remains around the pipe, and the service lid is reinforced by the rib, so that the service lid is hardly damaged.

As described above, according to the present invention, there is an effect that the pipe take-out portion can be formed without trouble.
