Description

[Detailed Description of the Invention] The present invention relates to a motor mounting plate fixing device for an outdoor unit of a room air conditioner, etc.

2. Description of the Related Art Conventionally, a motor mounting plate fixing device for an outdoor unit of this kind has a structure as shown in FIG. That is, the lower part of the motor mounting plate 12 on which the motor 11 is mounted is bent to form a mounting piece 13, and the mounting hole 14 provided in this mounting piece 13 is used to attach the mounting base 15.
A compressor chamber 18 is constituted by a partition plate 16 and a heat exchanger 17, which are fixed with screws (not shown) and placed on the mounting base 15. Furthermore, the motor 11
Blades (not shown) are attached to the unit to form the outdoor unit of the room air conditioner, which is connected to an indoor unit (not shown) via piping for heating and cooling.

The mounting hole 14 is positioned as close as possible to the bent portion of the mounting piece 13, taking into account vibrations and drops during transportation to the location where the outdoor unit is installed, and the motor mounting plate 12 is fixed with screws. It was hot.

Problems to be Solved by the Invention In such a conventional configuration, since the mounting hole 14 is provided near the bent portion of the mounting piece 13, the motor mounting plate 12 cannot be screwed onto the mounting base 15. When fixing, an air driver or the like hits the motor 11 at the top, making it difficult to tighten the screws, making the fixing work difficult and requiring a large number of man-hours.

This invention solves these problems, taking into account vibrations and drops during transportation.
The purpose is to make screw tightening work easier and reduce the number of work steps.

Means for Solving the Problem In order to solve this problem, the present invention is to form a mounting piece by bending the lower part of the motor mounting plate on which the motor is mounted on the upper part, and to form a mounting hole in this mounting piece. At the same time, a fixing piece is cut out from the mounting piece and is located below the mounting plate by the thickness of the mounting plate and protrudes in the opposite direction to the protruding direction of the mounting piece. The fixing piece is fixed by being hooked into a hole provided in the mounting base.

Effect: With this configuration, the screw-fastening portion can be selected at a position distant from the vertical portion of the motor mounting plate, and the screw-fastening work can be facilitated.

Embodiment An embodiment of the present invention is shown below in Figs. 1 and 2.
This will be explained based on the diagram. In the figure, reference numeral 2 denotes a motor mounting plate on which the motor 1 is mounted, and has a mounting piece 3 formed by bending the lower part at right angles. Then, the screw 4a (second
(Fig.) is screwed and fixed to the mounting base 5 through the mounting hole 4 into which it is screwed. A fixing piece 6 is cut and raised on the mounting piece 3 and is located below by the thickness of the mounting base 2 and projects in a direction opposite to the direction in which the mounting piece 3 projects. This fixing piece 6 is hooked onto one end edge of a square hole 7 provided in the mounting base 5 to be fixed. A partition plate 8 and a heat exchanger 9 are mounted on the mounting base 5, and these constitute a compressor chamber 10.Furthermore, blades (not shown) are attached to the motor 1, and the blades (not shown) are attached to the motor 1. It constitutes an outdoor unit.

In the above configuration, in order to withstand vibrations and falls during transportation to the location where the outdoor unit is installed, it is necessary to fix the fixing piece 6 as close as possible to the bent part of the mounting piece 3. By hooking and fixing to the square hole 7 provided on the base 5, the mounting hole 4 is fixed at the bent part. Since the screwdriver can be separated from the motor mounting plate 2, the screwdriver does not hit the motor 1 or the motor mounting plate 2, making it easier to screw the screws.

Effects of the Invention As is clear from the description of the above embodiments, the present invention involves cutting and raising a fixing piece on the mounting piece of the motor mounting plate, hooking the fixing piece into a hole in the mounting base, and fixing the fixing piece to the mounting piece. Since the screws are screwed to the mounting base at the end, the work of screwing the motor mounting plate becomes easier and there is no part to hit with an air driver, etc., reducing the number of man-hours, eliminating defects in screw tightening, and improving quality. Furthermore, since the fixed piece is fixed with a gap between the fixing piece and the screw stopper, even against vibrations, drops, etc. during transportation, the fixing strength is improved compared to the conventional method.
