Abstract

<P>PROBLEM TO BE SOLVED: To further reduce the quantity of steel plate to be used required for manufacturing an installation plate fixed to a wall surface and locking an indoor machine of an air conditioner. <P>SOLUTION: A pair of L-shaped plates 2 and 3 being an object are molded by a press from one rectangular steel plate, and the inverted U-shaped installation plate 4 is formed. The L-shaped plates 2 and 3 form upper locking parts 2a and 3a and lower locking parts 2b and 3b for locking back face upper-lower parts of an indoor machine body, a plurality of installation holes 2c and 3c to the wall surface and joining parts 2d and 3d joined so as to become the inverted U-shaped installation plate. The left-right of the upper locking parts 2a and 3a are cut off, and both are allowed to abut on each other by arranging a level difference corresponding to the plate thickness of the other joining part in one of the joining parts 2d and 3d, and are joined, for example, by spot welding, and the inverted U-shaped installation plate 4 is formed. The steel plate having the area corresponding to a void part of a lower central part of an inverted U-shape can be saved more than the conventional same-shaped installation plate by the installation plate 4 composed of such a constitution. <P>COPYRIGHT: (C)2004,JPO

Description

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to an installation plate that is fixed to a wall surface of a room to be air-conditioned and locks an indoor unit of a separation type air conditioner.
[0002]
[Prior art]
As an installation plate for locking an indoor unit of a separation-type air conditioner having a piping unit or the like between an outdoor unit and an indoor unit, there is, for example, one shown in FIG. The mounting plate 21 is used for mounting on the wall surface 23 and the like, as shown in FIG. A plurality of mounting holes 21e are provided, and locking holes 21f corresponding to locking claws 22a on the indoor unit main body 22 side are provided in the lower locking portions 21c and 21d.
[0003]
The mounting plate 21 described above is only an example, and there are other mounting plates of various shapes (for example, refer to Patent Document 1). Not only is it difficult to reduce the cost, but also there is a problem that much labor is required for mounting on a wall.

[0005]
[Problems to be solved by the invention]
In view of the above problems, an object of the present invention is to provide an installation plate of an air conditioner that is manufactured from a steel plate having a smaller area.
[0006]
[Means for Solving the Problems]
The present invention has been made in order to solve the above-mentioned problems, and includes a rectangular steel plate, a target L-shaped mounting surface having a mounting hole to a wall or the like, and a vertical rear surface of an air conditioner main body. An upper locking portion and a lower locking portion for locking the upper portion and a connecting portion for connecting the L-shaped mounting surfaces so as to form an inverted concave are continuously provided, and the left and right sides of the upper locking portion are cut off. The pair of L-shaped plates is press-formed, and one of the L-shaped plates is turned upside down to join the joints to form an inverted concave mounting plate.
[0007]
Further, a configuration is provided in which a joint surface of one of the L-shaped plates is provided with a step surface corresponding to the thickness of the counterpart plate.
[0008]
In addition, a configuration is provided in which a stepped surface corresponding to the thickness of the mating side is provided at a joint portion of one of the L-shaped plates, and a fitting portion that fits the stepped surface is provided in the other L-shaped plate. And
[0009]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 is a plan view of a steel plate used for forming an indoor unit installation plate, FIG. 2 is a perspective view of an indoor unit installation plate formed from the same steel plate, and FIG. 3 is an indoor unit showing another embodiment. FIG. 2 is a perspective view of a main part of a mounting plate for use.
[0010]
In the figure, reference numeral 1 denotes a rectangular steel plate having a minimum area required for forming a mounting plate. According to the present invention, the rectangular steel plate 1 has a plurality of mounting holes 2c, 3c formed on a wall or the like. L-shaped mounting surfaces (2), (3), upper locking portions 2a, 3a and lower locking portions 2b, 3b for locking the upper and lower rear surfaces of the air conditioner main body (indoor unit main body); L-shaped attachment surfaces (2) and (3) are connected to joining portions 2d and 3d for joining each other so as to form an inverted concave shape, and left and right 2e, 2f, 3e of the upper locking portions 2a and 3a. A pair of L-shaped plates 2 and 3 from which 3f has been cut are press-formed, and one of the L-shaped plates is turned upside down to join the joints 2d and 3d together. A plate 4 is formed.
[0011]
A broken line marked on the rectangular steel plate 1 indicates an upper locking portion 2a, 3a and a lower locking portion 2b, 3b as shown in FIG. 2 and a pair of L-shaped plates 2, 3 cut into an L shape. It shows the position of the bend when forming the joints 2d, 3d to be joined in an inverted concave shape, and the hatched parts 2e, 2f, 3e, 3f are unnecessary and are cut off to form the installation plate as shown in FIG. Area. The lower locking portions 2b and 3b are formed with locking holes 2g and 3g corresponding to locking claws and the like (not shown) on the indoor unit side, and the whole is bent forward. The lower locking portions 2b and 3b and the upper locking portions 2a and 3a are not necessarily limited to this form.
[0012]
Also, a step (step surface) corresponding to the thickness of the mating side (3d) is formed at the joint 2d of one L-shaped plate 2, and the joint 3d of the L-shaped plate 3 abuts on the back side. The joint is formed by, for example, spot welding or a plurality of holes (not shown), which are screwed together to form a predetermined inverted concave mounting plate 4.
[0013]
FIG. 3 shows a second embodiment relating to the joints 2d, 3d. In this embodiment, the joint 3d of the L-shaped plate 3 is provided with a step surface corresponding to the thickness of the mating side (2d), It is characterized in that a fitting portion (symbol omitted) for fitting the step surface is provided in the L-shaped plate 2 on the other side. With such a fitting portion, a predetermined installation plate can be formed only by combining the two at the time of attachment to the wall surface, and the labor for assembling can be omitted.
[0014]
【The invention's effect】
With the installation device for an air conditioner having the above-described configuration, a steel plate having an area corresponding to the gap at the lower center of the installation plate formed in an inverted concave shape can be saved, and transportation and mounting work on a wall surface or the like can be performed. Not only is it easier, but as the size of the mounting plate becomes larger and as the mass production increases, the amount of steel plates that can be saved increases, resulting in a significant cost reduction.
