Description

[Detailed Description of the Invention] The present invention relates to an electrical component board mounting device suitable for a cooler or the like in which a drain is attached to the inside of the main body.

The inside of the cooler is cooled by a built-in cooler, and the condensate that adheres to the frame and the inner surfaces of both sides flows down along this path.For example, if you install an electrical board across these both sides, the flowing condensate will flow down the electrical board. There is a risk that the electrical components attached to this board may get wet due to the transmission. Conventionally, countermeasures have been taken for this purpose, such as forming the electrical board into a sealed box shape to cover the electrical parts, but this has had the disadvantage of increasing material costs and causing the temperature of the electrical parts to rise abnormally due to the sealed structure.

In view of these points, the present invention aims to provide an electrical component board mounting device that provides a drain blocking means to the electrical component board and allows the electrical component board to be easily assembled to the cooler body. In this case, the upper left and right corners of the electrical equipment board are bent in a stepped manner to form a descending sloping surface and a step surface, and the descending sloping faces of the electrical equipment board are inserted and guided into the left and right sides of the cooler body. A diagonal cut portion is formed which overlaps the stepped surface.

An embodiment of the present invention will be described below based on the drawings. In FIG. 1, 1 includes casters 2;
This spot cooler body is installed movably within the factory, and has a built-in compressor, cooler, radiator, blower, etc. Air drawn in from the intake grille 3 on the front side is cooled by the cooler. The rear flexible duct 4 cools the workers in the factory locally, and the air sucked in from the back side cools the radiator and is discharged upward from the exhaust grille 6 on the top plate 5 as hot air.

FIG. 2 is an enlarged front view of the main parts of the cooler body 1 showing a state in which the removable front panel 7 with the suction grill 3 is removed. Board 10
A and 10b are fixed to screws 11a and 11b, and a cooler 12 is disposed above these screws 11a and 11b. Reference numeral 13 denotes a rectangular electrical equipment board with a control knob 14 for operation on the front side and electrical components 15 such as a terminal board 15a and a capacitor 15b on the back side, and a bottom plate that is welded and fixed to the left and right side plates 10a and 10b. 16 and screws 17a, 17b
Notch holes 18a and 18b to be stopped are provided, and upper left and right corners 19a and 19b are bent in a stepwise manner to form downwardly inclined surfaces 20a and 20b for guiding drain flow downward.
and a mounting cross-section surface 22 for fixing the electrical equipment board 3 to the left and right side plates 10a, 10b with screws 21a, 21b.
a and 22b.

That is, the electrical equipment board 13 is made of a single board with left and right upper corners 19a, 19b and an upper side 23 extending out as shown in the exploded view shown in FIG.
and 25, the left and right upper corners 19a, 19b and the upper side 23 are bent approximately at right angles to the front side (front side), and the cross-sectional surfaces 22a,
22b is folded back parallel to the main body of the electrical equipment board 13 to form downwardly inclined surfaces 20a and 20b. Note that 27a and 27b are through holes for passing the screws 21a and 21b, and 28 is a shaft through hole for the knob 14.

FIG. 4 is an exploded perspective view of the main parts shown from the front side showing how the upper left corner 19a of the electrical equipment board 13 and the left side plate 10a are mounted, and FIG. 5 is a perspective view of the main parts shown from the back side with the mounting state shown in FIG. The electrical equipment board 13 has notched holes 18a and 18 in the screws 17a and 17b temporarily fixed to the bottom plate 16.
b are engaged, and the cross-sectional surfaces 22a, 22b are attached to the front surface of the diagonal cut portions 29 of the left and right side plates 10a, 10b from the front side using the edges of the cut portions 29 to lower the downward slope surface 20.
a and 20b are inserted and guided so that they come into contact with each other, and the holes 27
It can be easily attached by fastening screws 21a and 21b to each other and tightening screws 17a and 17b. Moreover, when the electrical equipment plate 13 is installed, the left and right side plates 10a, 1 are
Drain water droplets 3 flowing down the front side of 0b as shown in Figure 2

2b through the gap between the descending slopes 20a and 20b.
Drain water droplets 32 flowing further downward and on the back sides of the left and right side plates 10a and 10b as shown in FIG. This prevents the electrical components 15 mounted on the back surface of the plate 13 from getting wet. Incidentally, the descending slope surfaces 20a and 20b have their inner edges 3
If the third side is made higher than the outer edge 34 side and also tilted forward, the drain water droplets 31 and 32 can flow down along the outer edge 34 and can be more reliably prevented from going around to the back side of the electrical equipment board 13.

As described above, according to the present device, the descending slope surface and the step surface are formed by the simple operation of bending the left and right upper corners of the electrical component board into a step shape, so that water flows down from the left and right side plates of the cooler main body along the step surface. Since the drain water droplets are received by the descending slope and flow down from the sides of the electrical equipment board, it is possible to prevent the electrical components attached to the electrical equipment board from getting wet.

In addition, diagonal cut portions are formed on the left and right side panels of the cooler body to insert and guide the downwardly inclined surface of the electrical equipment board and overlap the step surface, making it easy to align the step surface when attaching it to the diagonal cut portion. This makes it possible to improve the workability of assembling the electrical equipment board.
