DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high humidity refrigerator for storing foods in a humid state.

[0002]

2. Description of the Related Art In recent years, in the distribution of foods, various techniques have been put into practical use, such as refrigerated storage, frozen storage, partial storage, and high humidity storage, from the viewpoint of maintaining the freshness of food.

An example of the above-mentioned conventional high humidity refrigerator will be described below with reference to FIGS.

[0004] Reference numeral 1 denotes an under-counter type refrigerator used in a cooking place such as a restaurant. A main body 5 comprising an outer box 3 and an inner box 4 filled with a heat insulating material 2 and a heat insulating material 2 provided in the inner box opening 4a. Refrigerator doors 6a, 6b,
A machine room 10 is provided on the left side of the main body 5 for accommodating the compressor 7, the condenser 8, and the condenser fan 9 therein. Numeral 11 denotes a heat insulating box provided in the upper part of the machine room, which is press-fitted into the side opening 5a of the main body 5, and has therein an evaporator 12, a drain pan 13 for receiving defrost water, and cold air cooled by the evaporator 12. Is provided with an evaporator fan 14 for sending air. On the other hand, an inner box 16 is provided on the inner surface of the inner box 4 at predetermined intervals to form an air layer 15.
And a fixing plate 17 in which the inner box 4 is partially and closely adhered to the respective surfaces.

The operation of the high humidity refrigerator configured as described above will be described below. The cool air cooled by the evaporator 12 is discharged by the evaporator fan 14, passes through the air layer 15 between the inner box 4 and the inner box 16, and returns to the evaporator 12, whereby the cooled inner box 16 is cooled. The interior of the refrigerator is indirectly cooled using Also, when inserting and fixing the inner box 16 into the inner box 4, the assembled part of the inner box 16 is inserted into the inner box opening 4a from the back, passes over the lower fixing plate 17, and hits the rear fixing plate 17. And then fixed with screws or the like (not shown).

[0006]

However, in the above configuration, when the interior box 16 is attached to the inner box 4, the assembly of the interior box 16 is inserted into the inner box opening 4a from the rear surface, so that the inner box 16 is fixed. The interior box 1 has to climb over the plate 17
In the case where 6 is large and wide, it is particularly difficult to lift and the workability is remarkably deteriorated. In addition, after inserting the inner box 16, it is necessary to fix the inner box 16 and the fixing plate 17 with screws or the like. There was a problem that the number of man-hours increased.

The present invention has been made to solve the above problems, and
It is intended to facilitate the work of attaching the interior box to the inner box and to reduce the number of steps.

[0008]

In order to achieve the above-mentioned object, an insertion guide is provided on the lower surface of the inner box, which is inclined higher toward the back than the opening of the inner box and has a recess in the middle, and the insertion guide is provided on the lower surface of the inner box. An installation plate is provided which is in close contact with the recess.

[0009]

According to the present invention, when the interior box is inserted into the inner box by the above-described configuration, the interior box can be fixed by simply inserting the interior box along the insertion guide and inserting the installation plate into the recess provided in the middle of the insertion guide. It is intended to improve workability and reduce man-hours.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. The same components as those in the conventional example are denoted by the same reference numerals, and detailed description will be omitted.

An insertion guide 18 is provided on the lower surface of the inner box 4 which is inclined higher toward the back than the inner box opening 4a and is provided with a recess 18a in the middle thereof, and is fixed with screws or the like (not shown). An installation plate 19 is provided on the lower surface of the inner box 16 at a position facing the recess 18a of the insertion guide 18.

The operation of the high humidity refrigerator configured as described above will be described below. The cool air cooled by the evaporator 12 is discharged by the evaporator fan 14, passes through the air layer 15 between the inner box 4 and the inner box 16, and returns to the evaporator 12, whereby the cooled inner box 16 is cooled. The interior of the refrigerator is indirectly cooled using At the time of assembly work, the interior box 16
When inserting and fixing the inner box 4 into the inner box 4, the assembly of the inner box 16 is first placed on the lower surface of the inner box 4 in the inner box opening 4 a and then pushed toward the back of the inner box 4. And the joint on the back is pushed along the insertion guide 18,
It is inserted until it hits the fixing plate 17 without any contact. After insertion, the recess 1 near the middle of the insertion guide 18 in the depth direction
The installation plate 19 is fitted into 8a, and the inner box 4 and the inner box 16 are fixed.

According to this embodiment, since the interior box 16 is inserted along the insertion guide 18, it is not necessary to lift the large interior box 16 and the workability is improved. At the same time as the interior box 16 is inserted, the installation plate 19 attached to the interior box 16 is fitted into the recess 18a provided in the insertion guide 18, so that the interior box 16 and the inner box 4 are fixed. The necessary fixing work is not required.

[0014]

As described above, according to the present invention, since the insertion box is attached to the lower surface of the inner box, the inner box is inserted along the insertion guide, so that the operation of inserting the inner box is facilitated and the workability is improved. .

Further, since the installation plate attached to the interior box is fitted and fixed in the concave portion provided in the insertion guide, the work of fixing the lower surface is eliminated, and the number of steps can be reduced.
