Abstract

(57) [Summary] [Purpose] The purpose of this work is to avoid the trouble of forming holes for taking out refrigerant pipes. [Structure] Since the detachable service lid is provided with a pipe outlet and ribs are provided around the pipe outlet, this service lid can be removed from the indoor unit (housing),
The work for forming the pipe take-out portion can be performed, and the pipe take-out work can be easily performed. Further, the installation work of the indoor unit itself can be simplified as compared with the conventional one. Moreover, since the rib remains around the pipe outlet, the service lid is reinforced by the rib, and the service lid is less likely to be damaged.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an indoor unit of an air conditioner in which a refrigerant distribution, a terminal plate, etc. are housed in a housing.

[0002]

[Prior art]

 Conventionally, as an indoor unit of this type of air conditioner, there is one as disclosed in Japanese Utility Model Publication No. 62-31791.

The air conditioner shown in this publication has a refrigerant pipe and a terminal board for connecting indoor and outdoor heat exchangers, and a groove having a thin wall is formed in the lower portion of the housing. ing . Then, if necessary, a part of the housing is cut off at the groove portion to form a hole for taking out the refrigerant pipe.

[0004]

[Problems to be solved by the device]

 The indoor unit of such an air conditioner has the following drawbacks. When a part of the housing is cut off, if the operator fails to work or the housing is cracked and the housing is cut off more than is necessary or damaged, replace the large housing or replace the indoor unit as a whole. I had to do it. Also, chips may get inside the indoor unit during work. In order to prevent the above-mentioned drawbacks, the operator has to carefully perform the disconnection work, and the work is very troublesome.

According to the present invention, the work of forming the hole for taking out the refrigerant pipe is not troublesome.

[0006]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention incorporates an indoor heat exchanger, an electrical component, and a terminal board connected with the lead wires of the electrical equipment in the housing, and a service lid for covering the terminal board is provided in the housing. In an indoor unit of an air conditioner that is detachably attached, the service lid is provided with a pipe outlet for guiding the refrigerant pipe extending from the indoor heat exchanger to the outside of the housing, and the periphery of the pipe outlet. The ribs are provided on the.

[0007]

[Action]

 When guiding the refrigerant pipe to the outside of the housing, first remove the service lid from the housing, hold the removed service lid in your hand, and cut out the pipe outlet to form the pipe outlet. A rib remains around the pipe outlet. Then attach the notched service lid to the main unit.

【Example】

 FIG. 1 shows an indoor unit of an air conditioner according to the present invention. 1 is an indoor unit, and the back surface 2 side can be installed on the wall surface of the room. 3 is a suction grill formed in the upper part of the body of the heat exchange unit, 4 is a discharge port formed in the lower part of the body, and a wind direction changing blade 5 is provided in the discharge port. 6 is a plate fin type heat exchanger built in this main body.

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

A service lid 16 covers the terminal board 11 and is made of resin and is detachably attached to the lower surface 17 of the indoor unit 1. When installing the indoor unit, the service lid 16 is removed, and the inter-unit wiring and ground wire are connected to the terminal board 11 from below the indoor unit 1. Of course, after connecting the wiring cord between the units and the ground wire to the terminal board 11, the terminal board 11 is covered with the service lid 16.

FIG. 2 shows a perspective view of the service lid. The service lid 16 is composed of a portion 18 that covers the terminal board 11 and a portion 20 through which the refrigerant pipe 19 passes. Further, ribs 21, 22, 23 are formed in a U shape inside the service lid 16, and grooves 24, 25 are formed inside the ribs 21, 22, 23. . Of these grooves, the groove 25 on the rib 22 side is formed deeper than the other grooves 24 and grooves (not shown) inside the ribs 23. When the refrigerant pipe 19 is arranged so as to extend to the lower portion of the indoor unit 1, the portion surrounded by the ribs 21, 22 and 23 in a U shape may be separated from the service lid 16. In this case, first, cut along the groove 24 of the service lid 16 and the groove inside the rib 23, and bend at the groove 25, the service lid 16 easily breaks along the groove 25, and the ribs 21, 22, 23. You can easily cut out the part surrounded by. In this manner, the service lid 16 in which the portion 20 of the service lid 16 is cut out, that is, the pipe outlet 20 is opened, is attached to the indoor unit 1, and then the pipe outlet 20 is indicated by the alternate long and short dash line in FIG. Guide the refrigerant pipe 19 to the outside of the indoor unit as shown. The work of forming the pipe outlet 20 on the service lid 16 can be performed even when the indoor unit 1 is 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 service lid is formed with a rib having a U-shaped groove, the groove or rib serves as a guide to facilitate cutting, and the refrigerant pipe outlet 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 on the service lid. Ribs provide reinforcement for the service lid.

In the present invention, it is easy to form a passage of a size for passing the refrigerant pipe or processing is carried out by ribs or grooves formed on the back surface of the service lid so that the appearance is not unsightly. The processing may be formed by notches or holes.

[0015]

[Effect of device]

 As described above, in the indoor unit of the air conditioner of the present invention, the indoor heat exchanger, the electrical equipment, and the terminal board to which the lead wires of this electrical equipment are connected are built in the housing, and the service lid that covers this terminal board is built in. In the indoor unit of the air conditioner in which the housing is detachably attached, the service lid is provided with a pipe outlet for guiding the refrigerant pipe extending from the indoor heat exchanger to the outside of the housing, and Since a rib is provided around the pipe outlet, the service lid can be removed from the indoor unit (housing) to form the pipe outlet, which simplifies the pipe outlet operation. The installation work of the indoor unit itself can be simplified compared to the conventional one in which a part of a larger indoor unit is separated to form the pipe outlet. Moreover, when the pipe outlet is cut out, ribs are left around this and the service lid is reinforced by this rib, so the service lid is less likely to be damaged.

As described above, the present invention has an effect that the pipe lead-out portion can be formed without trouble.
