Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a refrigerator for storing frozen foods, refrigerated foods, medicines, etc. that require frozen or refrigerated storage.

(b) Prior art As a technology prior to the present invention, the Japanese Utility Model Publication No. 62-29903
There is a case described in the publication. A lighting room is formed on the front surface of the upper wall of the show case by bending and extending the outer box downward, and the opening of the lighting room on the side of the refrigerator is made of a transparent material and can be opened and closed freely.

(c) Problems to be solved by the invention In the conventional technology, when a fluorescent light installed in a lighting room burns out, it must be replaced from within the refrigerator compartment, and articles stored in the refrigerator compartment must be taken out each time. This made it difficult to carry out the replacement work smoothly.

In addition, since the transparent body is detachable, it is not possible to insulate the light room sufficiently, and if it is a fluorescent light, it will be cooled down, which often causes lighting failures, and the refrigerator compartment around the light room cannot be used. The temperature distribution within the refrigerator compartment also became non-uniform due to the temperature rise in the parts.

The present invention was made in view of the problems of the conventional technology, and provides a cooling cabinet that reduces the temperature influence of lighting on the storage compartment, provides good lighting in the storage compartment, and allows for smooth replacement of lighting. The technical task is to provide this information.

(d) Means for Solving the Problems The present invention forms a lighting room that spans the storage room and the outside of the storage room in a heat insulating box that forms the storage room, and attaches a transparent body to the opening of the lighting room on the storage room side. The problem can also be solved by installing a lighting lamp inside the lighting room and covering the opening of the lighting room outside the storage room with an exterior plate of the heat insulating box so that it can be opened and closed.

The lighting room is formed on the wall that allows the storage chamber in the heat insulating box to communicate with the outside, and in the case of a refrigerator having a machine room at the bottom, it is formed on the top wall and the peripheral wall.

The illumination light may be anything that emits light, such as a fluorescent lamp or an incandescent lamp, and illuminates the storage room through the transparent body.

The refrigerator may be either refrigerated or frozen, and the lighting room and the storage room are separated by a transparent material, so that it is preferably formed of a plurality of transparent plates to improve heat insulation.

(E) Effect In the present invention, light from the illumination lamp passes through the transparent body and illuminates the storage room, and by opening the exterior plate, the illumination light in the illumination room can be replaced from outside the storage room.

(F) Embodiment A show case used for face-to-face sales of meat, prepared foods, etc. will be illustrated as an embodiment, and the structure of the present invention will be concretely explained based on the drawings.

FIG. 2 shows a perspective view of the show case 1. The show case 1 has a machine room 2 in the lower part and a storage room 3 in the upper part. The machine room 2 is equipped with cooling devices such as a compressor, a condenser, an evaporator, and a blower, and cools the room by sending cold air into the storage room 3. Further, in the case of a structure in which the storage chamber 3 is directly cooled, a cooler may be provided on the inner surface of the storage chamber 3 or the lower surface of the shelf 4.

The storage room 3 includes a heat insulating box 9 formed by upper, lower, left and right walls 5, 6, 7, 8, a transparent plate 10 that closes the front opening of the heat insulating box 9, and a heat insulating box 9 that opens and closes the rear opening of the heat insulating box 9. It is formed from the door body 11. Insulated box body 9
is formed by foaming a heat insulator between the inner and outer boxes, and the inner and outer boxes are molded from sheet metal or synthetic resin. The heat insulating door body 11 is formed by foaming a heat insulating material into the inner box and the outer box, and is rotatably attached to the rear opening of the heat insulating box body 9 with a hinge body. The heat insulating door body 11 may be attached to the heat insulating box body 9 in the form of a sliding door. The heat insulating door body 11 may be formed by stacking a plurality of transparent plates with an air layer interposed therebetween. The transparent plate body 10 that closes the front opening of the heat insulating box body 9 is made by stacking a plurality of plates with a gasket 12 interposed around them.
The sash body 13 is airtightly attached to the stepped portion around the front opening of the sash body 13.

The upper surface of the upper wall 5 of the heat insulating box 9 is recessed so that projecting walls 14 are formed at the left and right front parts. An illumination light chamber 15 is formed in the front part of the upper wall 5 by a horizontally elongated hole communicating with the storage chamber 3. A plurality of transparent bodies 16 are hermetically fitted into the storage chamber 3 side of the illumination light chamber 15. The transparent body 16 has a packing 17 surrounding it,
They are overlapped to form an air layer to provide heat insulation between the lighting chamber 15 and the storage chamber 3. A heater 18 for preventing dew condensation is attached to the transparent body 16 on the illumination light chamber 15 side. A clip 19 is attached to the inner wall of the lighting room 15, and a lighting body 20 is held in the clip 19. The illumination body 20 is formed of a fluorescent lamp. The upper opening of the illumination light chamber 15 is closed by a lid 21 that can be opened and closed. The lid body 21 is rotatably supported by a hinge body 22 on one side. The closed state of the lid body 21 is shown in FIGS. 1 and 3,
The open condition is shown in FIGS. 4 and 5. Lid body 2
1 protrudes from the upper surface of the upper wall 5 in the closed state. The lid body 21 is made of sheet metal, and the illumination body 20
The lower surface facing the illumination body 20 is formed with a white or silver color with high reflection efficiency, and serves as a reflecting mirror for the illumination body 20.

A top plate 22, which is an exterior plate, is attached to the upper surface of the upper wall 5 so as to be substantially flush with the upper surface of the projecting wall 14.
The top plate 22 is detachable and covers the illumination light chamber 15 so that it can be opened and closed. In this structure, the top plate 22 is slid rearward to cover the illumination light chamber 15 so as to be openable and closable. Further, although the lid body 21 is interposed between the top plate 22 and the illumination light chamber 15, the illumination light chamber 15
will be indirectly covered by the top plate 22. The top surface of the show case 1, that is, the top surface of the top plate 22, is used as a place for placing stored items, a place for passing products to customers during sales, and a display stand, so it needs to be well-decorated and strong. Ru. This structure has a three-layer structure consisting of sheet metal, urethane coated, and glass plates stacked on top of each other. L-shaped guide bodies 23 are formed on both sides of the top plate 22. In this structure, the guide bodies 23 are formed by spot welding on both sides of the sheet metal of the top plate 22, but the guide bodies 23 may be formed integrally by cutting them up.

Guide bodies 23 are provided on both inner surfaces of the projecting wall 14 of the upper wall 5.
A rail body 24 is formed to guide the. Top plate 2
2 is slid back and forth along the rail body 24, and in the state shown in FIGS. 1 to 3 in which the top plate 22 covers the top wall 5, the front end of the top plate 22 comes into contact with the inner surface of the projecting wall 14, The top plate 22 is placed on the lid 21 and
The top plate 22 is prevented from being opened and the top plate 22 is prevented from being bent by the lid body 21. Rearward sliding of the top plate 22 is prevented by a rear frame 26 that is attached to and detached from the rear end of the upper wall 5 with screws 25. The screws 25 may be screwed in using a jig, easily screwed in using a coin or the like, or formed into a head-sized screw that can be screwed in with fingers. The rear frame 26 may be formed integrally with the rear edge of the top wall 22.

The guide body 23 formed on the top plate 22 is formed on the rear side of the middle part, and when the top plate 22 is closed, the front end of the guide body 23 comes into contact with the rear end surface of the lid body 21. We are also working on positioning.

In this structure, the top plate 22 has a glass plate on its top surface,
Colored glass is used as the glass plate, and the urethane interposed between the metal plate and the glass plate has a heat insulating effect and also serves as an adhesive between the metal plate and the glass plate. So-called urethane is a double-sided adhesive tape.

Sliding support of the top plate 22 to the upper wall 5 is provided by integrally forming grooves on both inner surfaces of the projecting wall 14 to guide and support both sides of the top plate 22, and by a frame body that also serves as a sash for the projecting wall 14. You may.

Further, in this structure, the light from the illumination body 20 is irradiated only to the storage chamber 3, but the lid body 21 may be formed of a translucent material or may be omitted, and the top plate 22 may be formed of a translucent material. The top plate 22 can be illuminated with
The exhibition effect can be improved. When the entire top plate 22 is illuminated, the top plate 22 is formed by stacking a glass plate and a translucent synthetic resin plate, and a large number of grooves are formed in the synthetic resin plate facing the illumination body 20 so that the light from the illumination body 20 can be illuminated. It is better to disperse it throughout.
