Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention divides the interior of a chamber into two upper and lower chambers with a partition wall, and a cooler and a cool air circulation fan are provided in each chamber, and these are further covered. As described above, the present invention relates to a cooling storage which is provided with a unit cover in which a suction port and a blowout port are formed.

(B) Conventional technology As a conventional cooling storage of this kind, for example, Jitsuko Sho 55-
In the 23179 publication, the compartment is divided into two chambers by a partition wall,
A refrigerator in which an evaporator and a blower are provided at the rear of each chamber, a unit cover having an inlet and an outlet is provided in front of them, and both evaporators are attached to columns provided so as to face each other. Is disclosed.

Further, in Japanese Utility Model Laid-Open No. 62-2989, a mounting through hole is formed in a top wall portion of a heat insulating box, and a recess is formed below a mounting base that closes the through hole, and the mounting hole is mounted in the recess. A refrigerating apparatus is disclosed in which a refrigerating unit attached to the lower surface of a gantry is arranged and a unit cover is arranged below the refrigerating unit.

(C) Problem to be Solved by the Invention The former conventional technique has the advantage that the upper and lower evaporators, the blower, and the unit cover can be made common, but on the other hand, the internal space along the rear wall becomes a dead space, There was a problem that the effective volume in the inner depth direction was extremely reduced both in the upper and lower chambers.

In addition, since the evaporator of each room is attached to the support straddling both rooms, there is a problem that dew or frost is generated on the side of the room having a high temperature.

On the other hand, the latter conventional technique has an advantage that the effective volume in the refrigerator can be widened because a part of the cooling unit is disposed in the recess. However, since such a technology has only one room, it can be separated into two rooms by a partition wall like the former conventional technology.
If the cooling unit is divided into a chamber and the cooling unit is installed in the lower chamber in the same way as the upper chamber, the cooler will project downward in the refrigerator, so the unit cover that covers this will be different from that in the upper chamber. In the case of manufacturing one or sharing the unit cover with the one in the upper chamber, there is a problem that the cooler and the blower cannot be shared.

In view of various problems as described above, the present invention aims to increase the effective volume in the interior depth direction and to easily obtain two temperature zones in which upper and lower chambers are not influenced by each other. In addition, a cooler, a blower, which is installed in each of the upper and lower chambers,
Further, a cooling storage for the purpose of sharing a unit cover is provided.

(D) Means for Solving the Problem In order to achieve the above-mentioned object, the present invention divides the interior of the chamber into two upper and lower chambers with a partition wall, and forms an opening in the ceiling wall of the upper chamber, and the opening is formed. A recess is formed below the heat-insulating lid that closes the heat-insulating lid, and a cooler for the upper chamber and a cool air circulation fan attached to the lower surface side of the heat-insulating lid are provided in the recess. A unit cover having a suction port and a blowout port is disposed below, and a heat insulator spacer for forming a recess under the same conditions as the recess is disposed below the partition wall. A cooler for the lower chamber and a cool air circulation fan attached to the lower surface side of the partition wall are disposed in the recess of the partition wall, and a unit cover having an intake port and a blowout port is formed below the cooler and the circulation fan. It is a cooling storage that is arranged.

(E) Action According to the present invention, the cooler (11) for the upper chamber is attached to the lower surface of the heat insulating lid (9), and the recess formed under the heat insulating lid (9).
The cooler (21) for the lower chamber, which is disposed in (10), is attached to the lower surface of the partition wall (5), and is a recess formed under the partition wall (5).
Since it is arranged in (17), the effective volume in the depth direction of each chamber (6), (7) increases. Moreover, the coolers (11), (2) of each room (6), (7)
Since (1) is independently attached to the heat insulating lid (9) and the partition wall (5) respectively, it is possible to prevent temperature influence between the chambers.

Further, since the heat insulating spacer (18) forms a recess (17) under the same conditions as the recess (10) of the upper chamber (6) below the partition wall (5),
The cooler (21), the cool air circulation fan (23) and the unit cover (25) of the lower chamber (7) can be shared with those of the upper chamber (6).

(E) Example An example of the present invention will be described below with reference to the drawings. First
The figure is a vertical side view of the cooling storage of the present invention, FIG. 2 is a cross-sectional plan view of the same, and FIG. 3 is an enlarged view of a main part of FIG. 1. (1) is a heat insulating main body having a front opening, Assemble the inner box (2) made by connecting metal plates such as PVC steel plate into the outer box (3),
It is constructed by filling a foam insulation material (4) such as polyurethane foam between both boxes by an on-site foaming method. The inside of the compartment is partitioned by a partition wall (5) with a heat insulating structure, for example, into two rooms, an upper ice greenhouse (6) and a lower freezer compartment (7), and the front opening of each compartment can be opened and closed by a heat insulation door (8). Is blocked by.

Thus, an opening is formed at the rear of the top wall of the ice greenhouse (6), and a recess (10) is formed below the heat insulating lid (9) that closes the opening, including the opening. . Insulate the recess (10) in advance.
A cooler (11) dedicated to ice temperature and a cool air circulation fan (12) mounted on the lower surface of (9) are provided, and a drain pan (13) is provided below the cooler (11), and further these coolers (11 ), The circulation fan (12) and the drain pan (13) are provided with unit covers (14) covering them, respectively. The unit cover (14)
Forms a suction port (15) in the front part that faces the circulation fan (12), and forms a blowout port (16) in the rear part that discharges the cold air that has undergone heat exchange in the cooler (11) along the rear wall. ing.

On the other hand, the below the partition wall (5), the recess (10) under the same conditions, i.e. the height (H _L) and width (H _W) is the same size (H _L) and (H _W) Insulator spacer for forming recess (17) which is
