Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel of an ice making device, and more particularly to a structure of a heat insulating panel which is bent and used to form a heat insulating frame of an ice making device.

[0002]

2. Description of the Related Art A conventional heat insulating frame of an ice making apparatus combines an interior part which is a vacuum molded product such as ABS and a sheet metal part made of stainless steel or the like, and injects a foaming agent having a heat insulating effect therebetween. . The interior parts and the sheet metal parts had to be fixed to each other with rivets, screws, etc., after providing joints at the joints. Further, after the foaming agent has been foamed, post-processing such as foaming leakage has to be performed, and many man-hours have been required for assembling.

[0003]

As described above, the conventional ice making apparatus has a problem that it takes time to assemble the heat insulating frame. The present invention has been made in order to solve such a problem, and an object of the present invention is to provide a heat insulating panel of an ice making device in which a heat insulating frame can be easily assembled.

[0004]

A heat insulating panel of an ice making apparatus according to the present invention is provided with a plurality of panel portions each filled with a heat insulating material and a flexible bent portion provided between adjacent panel portions. A bent portion is curved to form a heat insulating frame, and the required dimension of the heat insulating frame is adjusted by the curvature of the bent portion. In addition,
The bent portion may be formed from a thin member, and a plurality of grooves may be formed at right angles to the direction in which the bent portion is curved. The plurality of panel portions and the bent portions can be integrally formed by blow molding.

[0005]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a heat insulating panel of an ice making device according to an embodiment of the present invention. Thermal insulation panel 1
Are formed by blow molding, and three panel parts 2 to
4 and a bent portion 5 provided between the panel portions 2 and 3 adjacent to each other and a bent portion 6 provided between the panel portions 3 and 4. As shown in FIG. 2, the inside of each of the panel portions 2 to 4 is filled with a heat insulating material 7, and the bent portions 5 and 6 are each formed of a thin member and have flexibility. I have.

[0006] As shown in FIG.
The bent portions 5 and 6 are bent by bending them, respectively, and are erected on the base component 8 constituting the bottom of the ice making device to form a heat insulating frame. The base component 8 is formed by blow molding, and has a heat insulating material filled therein. The heat insulation panel 1 is bent in a plane U-shape,
The panel portions 2 and 4 form left and right side walls of the heat insulating frame, and the panel portion 3 forms the rear wall of the heat insulating frame.

[0007] Since the ice making section is arranged inside the heat insulating frame together with the evaporator of the refrigeration circuit, if an error occurs in the width dimension W and the depth dimension L inside the heat insulating frame as shown in FIG. The evaporator cannot be installed. However, in this embodiment, since the bending portions 5 and 6 having flexibility are provided between the panel portions 2 and 3 and between the panel portions 3 and 4, respectively, the bending of the bending portions 5 and 6 is performed. , The required dimensions inside the heat insulating frame, that is, the width dimension W and the depth dimension L can be easily adjusted. For example, when the curvature is reduced as shown in FIG. 5B as compared with the bent portion 5 which is curved as shown in FIG. 5A, the width dimension W and the depth dimension L inside the heat insulating frame can be reduced, Conversely, when the curvature is increased as shown in FIG. 5C, the width dimension W and the depth dimension L inside the heat insulating frame can be increased. Furthermore, by making the bent portion 5 straight as shown in FIG. 5D, the width dimension W and the depth dimension L inside the heat insulating frame can be maximized. Further, depending on how the bent portion 5 bends, one of the width dimension W and the depth dimension L inside the heat insulating frame can be increased and the other can be decreased. For example, FIG.
In (b), a bent portion 5 is formed at a portion near the panel portion 2.
Is curved, the width dimension W inside the heat insulating frame becomes large and the depth dimension L becomes small. Further, when the bent portion 5 is bent at a portion close to the panel portion 3, the width dimension W inside the heat insulating frame is reduced and the depth dimension L is increased.

In this manner, the width W and the depth L inside the heat insulating frame can be adjusted to desired dimensions. In particular, since the blow molding tends to cause a molding error, the adjustment of the required dimensions of the heat insulating frame by the bent portions 5 and 6 as described above is extremely useful.

As shown in FIG. 6, if a plurality of grooves 9 are formed at right angles to the direction in which the bent portions 5 and 6 bend, the bent portions 5 and 6 are more easily bent, and the heat insulating frame is formed. The fine adjustment of the size of can be easily performed. For example, when the curvature is reduced as shown in FIG. 7B as compared with the bent portion 5 curved as shown in FIG. 7A, the width dimension W and the depth dimension L inside the heat insulating frame can be reduced, Conversely, when the curvature is increased as shown in FIG. 7C, the width dimension W and the depth dimension L inside the heat insulating frame can be increased. Furthermore, by making the bent portion 5 straight as shown in FIG. 7D, the width dimension W and the depth dimension L inside the heat insulating frame can be maximized. Also, depending on how the bent portion 5 bends, one of the width dimension W and the depth dimension L inside the heat insulating frame is increased,
The other can be smaller. For example, in FIG. 7B, when the bent portion 5 is bent at a portion close to the panel portion 2, the width dimension W inside the heat insulating frame increases and the depth dimension L decreases. Further, when the bent portion 5 is bent at a portion close to the panel portion 3, the width dimension W inside the heat insulating frame is reduced and the depth dimension L is increased.

[0010]

As described above, according to the present invention, a flexible bent portion is provided between adjacent panel portions, the bent portion is curved to form a heat insulating frame, and the bent portion is formed. Since the required size of the heat insulating frame is adjusted by the curvature of the curvature, the dimensional error can be absorbed by the bent portion, and the heat insulating frame of the required size can be easily assembled. The bent portion can be formed from a thin member, and furthermore, if a plurality of grooves are formed at right angles to the direction in which the bent portion is bent, the bent portion is easily bent, and the assembling of the heat insulating frame is further facilitated. . If the plurality of panel portions and the bent portions are integrally formed by blow molding, the number of manufacturing steps is further reduced.
