Description

Detailed Description of the Invention a. Industrial application This invention applies static electricity to the inner box to thaw food,
The present invention relates to a heat insulating box provided with a static electricity generating device for storage.

b. 2. Description of the Related Art FIG. 4 is an overall perspective view showing an example of a conventional heat insulating box,
FIG. 7 is an enlarged view of a main part in FIG. 4, FIG. 6 is a perspective view of the state in which the corner cover of FIG. 4 is removed, and FIG. 7 is VII in FIG.
FIG. 7 is a cross-sectional view taken along a plane along the line VII, and the heat insulation box 1 is
An outer box 2 having an inner bent portion 2a bent in the inner box, and an inner box 4 provided inside the outer box via a heat insulating material 3 are provided. On the periphery of the inner box 4, the outer bent portion 4a is bent outward.
Is provided so as to face the inner bent portion 2a. An opening 8 is formed in the front surface of the heat insulating box 1 by the decorative frame 6 provided so as to cover the outer bent portion 4a and the inner bent portion 2a.

A corner plate 10 having an L-shaped cross section is formed in a space 9 which is a corner of the opening 8 and where the decorative frames 6 face each other at a right angle. It is fixed by. On the back surface of the corner plate 10, a foamable tape 12 that is slightly larger than the dimension of the corner plate 10 in both directions is adhered. The foamable tape 12 has a gap 13 between the outer case 2 and the inner case 4 when the corner plate 10 is fixed to the outer case 2 and the inner case 4.
While being press-fitted into, the small heat insulating material 3 is prevented from leaking to the outside through the small gap 14 between the corner plate 10 and the decorative frame 6 to the outside of the decorative frame 6. Note that the corner plate
A conductive tape (not shown) is attached to the back surface of 10 to electrically connect the inner box 4 and the outer box 2.

The entire surface of the corner plate 10 and the surface of the end portion 6a of the decorative frame 6 are covered with a corner cover 15 having an L-shaped cross section. Claw portions 16a and 16b are formed on the front side and the rear side of the corner cover 15 made of flexible synthetic resin, respectively. Front claw 16a
Is locked to the protruding portion 10a of the corner plate 10. The claw portion 16b on the rear side is engaged with the bent portion 6b formed on the inner edge portion of the decorative frame 6.

In the heat insulation box 1 configured as described above, the corner plate 10 is screwed into the void 9 formed in the corner of the opening 8.
It is fixed by 11. At that time, the foam tape 12 has a gap 13
While being press-fitted in, it is projected from the small gap 14 to the surface side of the decorative frame 6. Then, at the corner of the opening 8, a corner cover
By pressing 15, the claw portion 16a of the corner cover 15 is in the projecting portion 10a of the corner plate 10, and the claw portion 16b is in the bent portion of the decorative frame 6.
The corner covers 15 are easily attached to the corners of the opening 8 by being easily locked to the respective 6b.

c. DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the conventional heat insulating box 1 as described above, the corner cover 15 can be easily attached to the corner of the opening 8 and food may be attached to the attachment of the corner cover 15. Since it does not require a screw, it has advantages such as being hygienic and aesthetically superior.

However, since the inner box 4 and the outer box 2 are electrically connected to each other by the conductive tape in the heat insulating box 1, the static electricity generator for applying the static electricity to the inner box 4 to defrost and store the food is insulated. There is a problem that static electricity is not applied to the inner box 4 when it is attached to the box body 1 and used.

d. Means for Solving the Problem In the heat insulating box body according to the present invention, the corner plate 23 that connects the outer box 2 and the inner box 4 and is fixed to the gap 9 is made of synthetic resin.

e. Function In this invention, the inner box 4 and the outer box 2 are electrically insulated, and static electricity is applied to the inner box 4 by the operation of the static electricity generator. At the same time as opening the door 24, switch
25 operates and the inner box 4 is grounded.

f. Embodiment An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an overall perspective view showing an embodiment of the present invention, in which the same or corresponding parts as in FIGS. 4 to 7 are designated by the same reference numerals,
The description is omitted.

In the figure, a cooling device 21 and a static electricity generating device 22 for defrosting and storing food by applying static electricity to the inner box are provided above the heat insulating box 20.

FIG. 2 is a perspective view of a main part of FIG. 1, and a corner plate 23 made of a synthetic resin having an L-shaped cross section is fixed to a space 9 formed by the decorative frames 6 facing each other at a right angle. There is.

FIG. 3 is a circuit diagram of FIG. 1, and when the door 24 of the heat insulating box 20 is opened, the switch 25 attached to the door 24 operates and the inner box 4 is grounded.

In the heat insulating box 20 configured as described above, the inner box 4 and the outer box 2 are electrically insulated by using the insulative corner plate 23, so that the inner surface of the inner box 4 and the outer box 2 are electrically insulated by the operation of the static electricity generator 22. Static electricity is applied to the box 4, and the food in the heat insulating box 20 is stored and thawed.

Further, when the door 24 is opened and the food in the heat insulating box 20 is taken out, the switch 25 is activated and the inner box 4 is grounded, so that there is no electric shock. G. As described above, according to the present invention, since the corner plate 23 is made of synthetic resin, static electricity is applied to the inner box 4, and the food in the inner box 4 is stored and thawed by static electricity, for example. The effect is that you can. Further, since the inner box 4 is grounded when the door 24 is opened, there is no electric shock when the food in the inner box 4 is taken out.
