[0002]

2. Description of the Related Art Conventionally, in this type of cooling storage, for example, Japanese Utility Model Publication No. 6-38303 (F25D11 / 0).
As shown in 2), a refrigerating apparatus including a refrigerant compressor, a condenser, and the like, and first and second coolers arranged in the storage and circulated and supplied with the refrigerant from the refrigerating apparatus are provided. A refrigeration system provided is disclosed. This refrigeration system is provided on the side of the heat insulation box, and one refrigeration system circulates and supplies the refrigerant to two coolers.

Further, in the case of a quick freezer (even in a freezer), it is necessary to make the thickness thicker than the heat insulating wall used in the refrigerator, and therefore, JP-A-5-87441 (F25D23).
It is desirable to use a panel type like the heat insulating box shown in / 06).

[0004]

When such a refrigerating apparatus is used as a quick freezer, the capacity must be increased, and therefore, the machine room must be enlarged as the compressor is enlarged. . The machine room is not necessary for the user, and if the machine room is located at the corner of the installation location, the usability will be improved, but if it is opposite, the usability will be very poor.

In addition, since the heat insulating walls of all refrigerators, freezers, and quick freezers have different heat insulating wall thicknesses, it is difficult to use common parts even though they are panel type, which has been a problem. The present invention
The present invention has been made in view of the above-mentioned problems, and provides a quick freezer with good usability and a quick freezer for the purpose of sharing parts.

[0006]

As a means for achieving the above-mentioned object, in the invention of claim 1, the heat insulating box body having a front opening and the heat insulating box body provided on both left and right sides of the heat insulating box body are provided. A cooling device, a machine room provided on both left and right sides of the heat insulating box, a compressor and a condenser provided in the machine chamber and constituting a refrigeration cycle together with the cooler, and the compressor and the condenser. The machine room can be made smaller than the machine room of a normal quick freezer because it is composed of a condenser cooling blower that cools the container, and the machine rooms that are downsized are arranged on the left and right. Even if either of the left and right machine rooms is located at the corner, the other machine room is small, so that it can be prevented as much as possible.

Further, in the invention of claim 2, the heat insulating panel having a predetermined thickness, the connector for integrally connecting and fixing the heat insulating panel, the left and right side walls, the rear wall, the bottom wall and the ceiling wall are the heat insulating panel. And a heat-insulating box body having an opening on the front surface, and when the heat-insulating panel is thicker than the connector, in relation to a heat-insulating spacer that makes the connector almost the same thickness as the thickness of the heat-insulating panel, a refrigerator, a freezer, The same connection tool can be used for any thickness of the heat insulation panel in the quick freezers.

Further, the storage chamber 9 in the heat insulating box 2 may be divided into a plurality of three or more chambers, each room may be provided with a cooler 11, and the same number of machine rooms 15 as the coolers 11 may be provided.

As shown in FIGS. 4 and 5, the heat insulating panel 5 constituting the bottom wall of the heat insulating box 2 has an outer plate 30 and an inner plate 31 each made of a steel plate or a synthetic resin plate, and these inner and outer plates 30, A frame member 33, which is a connector made of hard styrofoam, is sandwiched between the peripheral portions of the peripheral member 31 and a polyurethane foam or the like foam-filled in a space surrounded by the inner and outer plates 30, 31 and the frame member. And a heat insulating material 32. Since the frame member 33 has a size suitable for a heat insulating panel having the minimum thickness, a heat insulating spacer 39 is interposed between the frame member 33 and the outer plate 30. This heat insulating spacer 3
Reference numeral 9 is used to adhere to the outer plate 30 with an adhesive. still,

Here, the bottom corners of the inner surface of the body 9 of the heat insulating box 2, that is, the upper surface of the heat insulating panel 5 and the heat insulating panel 6,
A natural-curing waterproof sealant is applied to the corners formed by the inner surfaces of 7 and 8 over the entire circumference (note that other corners may be applied). This waterproof sealant is, for example, a silicone-based one-component RTV rubber (deoxime type), and is cured within a few hours after being applied, so that the heat-insulating panels 5, 6, 7 and 8 are bonded to each other at a joint portion. It prevents water leakage.

Although this waterproof sealant is applied and is in a state of swelling up to the storage chamber side, it is covered with the molding 47 immediately (before curing) after application. The molding 47 is formed by extrusion molding of a hard vinyl chloride resin, and is formed in a rectangular shape so as to match the shape of the corner portion coated with the waterproof sealant. That is, in the invention of claim 1,
A heat-insulating box body 2 having an open front surface, a cooler provided on each of the left and right sides of the heat-insulating box body 2 for cooling the inside of the heat-insulating box body 2, and a machine room 15 provided on both the left and right sides of the heat-insulating box body 2. A compressor 13 and a condenser 12 which are provided in the machine room 15 and constitute a refrigeration cycle together with the cooler, and a condenser cooling blower 14 which cools the compressor 13 and the condenser 12.
Therefore, the machine room 15 can be downsized as compared with the machine room 15 of the normal quick freezer 1. Since the downsized machine rooms 15 are arranged on the left and right, the machine room 15 Even if the chamber 15 is located at the corner, the other machine chamber 15 is small, so that it can be prevented as much as possible from getting in the way.

Further, in the invention of claim 2, the heat insulating panels 4, 5, 6, 7, 8 having a predetermined thickness and the connection for integrally connecting and fixing the heat insulating panels 4, 5, 6, 7, 8 are integrally formed. Ingredient 3
3, 36, 38, 41, and the left and right side walls, rear wall, bottom wall, and ceiling wall are composed of the heat insulating panels 4, 5, 6, 7, 8 and the heat insulating box body 2 having a front opening, and the heat insulating Panels 4, 5, 6,
When 7, 8 is thicker than the connecting pieces 33, 36, 38, 41, the connecting pieces 33, 36, 38, 41 are connected to the heat insulation panel 4 ,.
Due to the heat insulating spacer 39 having substantially the same thickness as 5, 6, 7, and 8, the thickness of any of the heat insulating panels 4, 5, 6, 7, and 8 of the refrigerator, the freezer, and the quick freezer 1. However, the connectors 33, 36, 38, 41 can be the same.

The machine room can be downsized compared to the machine room of a normal quick freezer because it is composed of a blower for a room. Even if it is located at a corner, the other machine room is small, so that it can be prevented as much as possible from getting in the way. As a result, it is possible to provide a quick-freezer with good usability.

According to the second aspect of the present invention, the heat insulating panel having a predetermined thickness, the connector for integrally fixing and fixing the heat insulating panel, the left and right side walls, the rear wall, the bottom wall and the ceiling wall are heat insulated. A refrigerator, a freezer, because it is composed of a panel and has a heat-insulating box body having an opening on the front surface and a heat-insulating spacer that makes the connector have substantially the same thickness as the thickness of the heat-insulating panel when the heat-insulating panel is thicker than the connector.
