Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner installation device installed on a wall surface in a room.

[0002]

2. Description of the Related Art Generally, in an indoor unit of a separation type air conditioner installed on a wall surface in a room, first a mounting plate is attached to the wall surface, and an upper part of the indoor unit is hooked on the upper part of the mounting plate.
After that, for example, a rod for opening a working space is sandwiched between the installation plate and the indoor unit, and the refrigerant pipe is connected at the lower rear side of the indoor unit. However, this work is performed by sandwiching the rod when the refrigerant pipe is the left pipe or when the refrigerant pipe to be connected is previously embedded in the indoor wall.

In such a case, after connecting the refrigerant pipe, remove the rod, and pay attention not to remove the upper end of the indoor unit, lift the indoor unit slightly and install the lower end of the indoor unit from above. Lock to the bottom of the plate.

[0004]

However, since the refrigerant pipe wound with the heat insulating material is located at the back of the indoor unit, there is a problem that the heat insulating material presses the lower portion of the installation plate.
When this pushes the lower part of the installation plate, when the indoor unit is lifted upwards and the indoor unit is removed from the installation plate, the lower edge of the indoor unit and the lower part of the installation plate become too tight, making it difficult to remove. There is a problem.

Therefore, an object of the present invention is to provide an air conditioner installation device that solves the problems of the above-mentioned conventional techniques and can set a constant force for easily removing the indoor unit from the installation plate. To provide.

[0006]

In order to achieve the above object, the present invention is to hook an upper part of an indoor unit on an upper part of a mounting plate,
In an air conditioner installation device in which the lower part of the indoor unit is locked to the lower part of the installation plate, a hook body having an engaging protrusion at the tip is provided at the lower part of the indoor unit, and a hook body is provided at the lower part of the installation plate. A support tool having an opening for supporting the joint projection is provided, and the support tool has a pair of gripping pieces forming the opening and a fixing tool for urging the pair of support pieces in the supporting direction of the engagement projection. The support piece is provided with a spring, and is opened laterally against the spring force of the fixing spring when the engaging protrusion is pulled upward.

[0007]

According to the present invention, when the lower part of the indoor unit is pressed toward the installation plate with the upper part of the indoor unit hooked on the upper part of the installation plate, the engaging protrusions of the hook main body are paired with each other. The indoor unit is fixed by being supported by the openings between the support pieces. When removing the indoor unit from the installation plate, if you lift the indoor unit upward, the upper part of the indoor unit will first come off the upper part of the installation plate, and the pair of support pieces will resist the spring force of the fixing spring. Opens to the side and the lower part of the indoor unit disengages from the lower part of the installation plate.

[0008]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an air conditioner installation device according to the present invention will be described below with reference to the accompanying drawings.

In FIG. 2, reference numeral 100 denotes an indoor unit. The indoor unit 100 includes a pre-filter 101, a cleaning filter 102, an indoor heat exchanger 103, and a cross flow fan 104.

A drain pan 105 is provided at the lower end of the indoor heat exchanger 103, and the drain pan 105 and the bottom plate 106 are provided.
An air outlet 107 is opened between the and. 108
Is a vertical blade, and 109 is a horizontal blade.

The indoor unit 100 is attached to the installation plate 1 which is previously fixed to the indoor wall 110 with screws (not shown).

When installing the indoor unit 100, first, the upper end 100a of the indoor unit 100 is hooked on the upper part 11 of the installation plate 1, and then a space forming tool such as a bar is formed between the indoor unit 100 and the installation plate 1 (see FIG. (Not shown) is sandwiched and a working space is provided therein, and the refrigerant pipe 112 of the indoor unit 100 and the refrigerant pipe (not shown) connected to the outdoor unit are connected in this working space. Reference numeral 114 is a heat insulating material formed of urethane foam or the like, and 115 is a drain hose.

When the connection work is completed, remove the rod,
While the upper end 100a of the indoor unit 100 is hooked on the upper portion 11, the indoor unit 100 is pressed toward the installation plate 1 to
The hook main body 113 is locked to the grip 21 of the installation plate 1.

Therefore, according to this embodiment, the gripping tool 2
It is characterized by the constitution of 1.

As shown in FIG. 1, the gripping tool 21 is provided with a pair of gripping pieces 23a and 23b, and the pair of gripping pieces 23a and 23b are attached to the boss portion 1a of the installation plate 1 via screws 25. It is fixed.

An opening 27 that can be opened and closed is provided at the upper ends of the pair of support pieces 23a and 23b, and in the lower part of the support pieces 23a and 23b, the direction in which the opening 27 is closed (the support direction of the engaging projection 113a, which will be described later). ), A pair of support pieces 23a, 23
A fixing spring 29 for urging b is provided.

At the tip of the hook body 113, as shown in FIG.
Referring to FIG. 3, an engaging protrusion 113a is formed. When the indoor protrusion 100 presses the indoor unit 100 toward the installation plate 1, the engaging protrusion 113a, as shown in FIG. Two
The opening 27 of 3b is pushed open and penetrates into the opening 27.

When the indoor unit 100 is further pressed,
As shown in FIG. 3c, the engagement protrusion 113a further expands the opening 27 and finally completely penetrates into the opening 27,
Supported there.

According to this, the upper part 100 of the indoor unit 100
While hooking a on the upper part 11, install the indoor unit 100 on the installation plate 1
The indoor unit 100 can be easily attached to the installation plate 1 only by pushing it to the side.

According to this embodiment, however, the indoor unit 1
The work of removing 00 from the installation plate 1 is also easy.

Conventionally, since the supporting member 21 having such a structure is not provided, when the heat insulating material 114 is insufficiently bent or housed, the heat insulating material 114 pushes the indoor unit 100 forward, so that the installation plate is installed. The force for removing the lower part of the indoor unit 100 from the lower part of No. 1 could not be set to a constant value, and the lower part of the indoor unit 100 was sometimes difficult to remove.

According to this, first, the entire indoor unit 100 is lifted upward. Then, since the hook body 113 is also lifted upward, as shown in FIG.
Against the spring force of 9, the pair of support pieces 23a, 23b open laterally, and the hook body 113 is disengaged from the opening 27.

That is, in this embodiment, the force that lifts the indoor unit 100 upward and removes it can be set by the force that opposes the spring force of the fixing spring 29, so that the hook body 113 is opened from the opening 27 of the support pieces 23a, 23b. Since it is possible to always remove the indoor unit 100 with a constant force, it is possible to perform an operation of removing the indoor unit 100 with a constant force as compared with the conventional one.

[0024]

As is apparent from the above description, according to the present invention, even when the refrigerant pipe is not bent or accommodated sufficiently,
The lower part of the indoor unit can be removed from the lower part of the installation plate with a constant force.
