Abstract

PROBLEM TO BE SOLVED: To enable accurately positioning of an electric part box on a base plate by a method wherein a square hole is formed in a base plate where the electric part box is mounted while a jaw member extending forward is formed in the bottom part of the electric part box to be arranged and secured along the underside of the base plate through the square hole of the base plate. SOLUTION: A refrigerating unit mounted on a lower rear part of the body of an automatic ice maker has a compressor carried on a base plate 4 with leg parts and an electric part box 8 is mounted on the base plate 4 by a square hole 6 and screws 7 formed in the base plate 4. In other words, in the mounting of the electric part box 8, the bottom part 15 of the electric part box 8 is formed in a shape of a square pan with a U shaped cross section and a jaw part 16 is arranged along the underside of the base plate 4 through the square hole 6 of the base plate 4 in such a manner as to extend forward from the bottom part 15 below the bottom part 15 by a length almost equal to the thickness of the base plate 4. Then, a jaw part 17 placed on the base plate 4 extending backward from the bottom part 15 is secured on the base plate 4 by a screw 7 to mount the electric part box 8.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting device for an electrical equipment box in an ice making machine or the like.

[0002]

2. Description of the Related Art In a conventional condensing unit, a mounting mechanism for an electrical equipment box is constructed by partially cutting and raising a unit base and bending it in parallel with the unit base, as shown in Japanese Utility Model Publication No. 7-49340. The insertion part is formed by, and the fixing plate of the electrical equipment box is inserted into the insertion part, and the electrical equipment box is mounted on the unit base.

However, it is generally difficult to improve the accuracy of the cut-and-raised work, and the dimensions of the insertion portion formed by the cut-and-raised work are apt to vary, so that the fixing plate of the electrical equipment box may rattle in the insertion portion, or There was a problem that it became difficult to insert the fixing plate of the electrical equipment box into the insertion part. Also, since the width of the cut-and-raised parts provided on the unit base is narrower than the width of the electrical equipment box, the adhesion between the fixing plate of the electrical equipment box and the cut-and-raised parts becomes poor, and the mounting position of the electrical equipment box is Since it easily swings to the left and right, accurate positioning was difficult. Furthermore, if the size of the electrical equipment box and the size of the base to which it is attached are almost the same, there is the disadvantage that the insertion part cannot be formed by cutting and raising, and there is a spatial restriction on the installation of the attachment mechanism. It was inevitable to receive.

SUMMARY OF THE INVENTION An object of the present invention is to enable the electrical equipment box to be accurately positioned and fixed with respect to a base plate to which the electrical equipment box of an ice making machine or the like is attached.

[0005]

For this reason, in the electrical equipment box mounting device according to the present invention, a square hole is formed in the base plate to which the electrical equipment box is mounted, and it extends forward from the bottom of the electrical equipment box below the bottom portion. A collar member is arranged along the lower surface of the base plate through the square hole, and a collar member extending rearward from the bottom of the electrical equipment box and mounted on the base plate is fixed to the base plate. Is configured.

That is, in general, it is relatively easy to machine a square hole in a base plate, and the machining accuracy can be increased.
By loosely inserting the collar member extending forward from the bottom of the electrical box into the square hole, the collar member can be accurately positioned with respect to the base plate, and thus extends rearward from the bottom of the electrical box. By fixing the brim member placed on the base plate to the base plate, the electrical component box can be accurately positioned on the base plate, and the electrical component box can be firmly attached easily.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention shown in the drawings will be described below. In FIG. 1, a freezing unit 2 attached to the lower back of the automatic ice maker body 1 is formed on a base plate 4 having legs 3, a compressor 5 attached on the base plate 4, and a base plate 4. The front projection 10 provided on the front vertical wall 9 of the base plate 4 is composed of the electrical equipment box 8 and the like mounted on the base plate 4 as described later by the square holes 6 and the screws 7. Hole 12 in wall 11
To the lower surfaces of the left and right inner flanges 13 formed at the lower end of the ice making machine body 1 respectively.
The base plate 4 is fixed by 4.

Further, as shown in FIGS. 2 and 3, the bottom portion 15 of the electrical equipment box 8 placed on the base plate is in the shape of a square plate having a substantially U-shaped cross section, and the bottom portion 15 serves as a base plate. 4 below the bottom 15 by a length approximately equal to the thickness of 4
The collar member 16 extending from the front to the square hole 6 of the base plate 4
The flange member 17 that is disposed along the lower surface of the base plate 4 through the base plate 15 and extends rearward from the bottom portion 15 and is placed on the base plate 4 is fixed on the base plate 4 by the screw 7, 8 is mounted on the base plate 4.

In this case, even if the square hole 6 is provided at a position close to the front vertical wall 9 of the base plate 4, the forming process of the square hole 6 is much easier than the cutting and raising process, Generally, since it is easy to improve the processing accuracy, even if the lateral width of the square hole 6 is relatively large as shown in the drawing, the flange member 16 can be easily inserted into the square hole 6 within the range. The square hole 6 can be precisely machined so that the number of methods is minimized.

Accordingly, the wide brim member 16 which is inserted into the square hole 6 and extends forward along the lower surface of the base plate 4 is located at a precise position with respect to the base plate 4 by the square hole 6, and
Since it is stably held, by fixing the rear collar member 17 to the base plate 4 with the screw 7,
The electrical equipment box 8 can be mounted on the base plate 4 relatively easily and firmly.

Moreover, the lower surface of the bottom portion 15 of the electrical equipment box 8 is formed by the square holes 6 formed in the base plate 4 into the ice making machine body 1.
Since the bottom surface of the bottom portion 15 is effectively cooled by the outside air because it is in contact with the outside of the electric component box, the temperature rise in the electric component box 8 is suppressed, and various electrical components installed in the electric component box 8 are thermally protected. It is possible to obtain a special effect that is practically excellent in that it can be prevented from becoming defective.

The present invention is not limited to an ice making machine, but a refrigerator,
It is needless to say that the same effects can be obtained by implementing the same in equipment such as a freezer, a storage, and a showcase.

[0013]

In the electrical equipment box mounting device according to the present invention, the electrical equipment is installed by inserting the front brim member from the bottom of the electrical equipment box into the square hole of the base plate which is relatively easy to machine and has high machining accuracy. The box can be accurately positioned on the base plate, and the electric equipment box can be firmly attached.
