Description

[Detailed Description of the Invention] The present invention relates to a cooling box body that improves cooling of the upper part of a storage chamber.

An embodiment of the present invention will be described below with reference to the drawings. 1 is a metal inner box 2, an outer box 3, and a foamed heat insulating material 4 filled between the two boxes.
A cooling box body whose main body is composed of a heat insulating wall 5, the upper surfaces of both sides of the heat insulating wall being curved to be higher than the top surfaces of the front and back walls, and a support having a signboard 7 at the apex. A body 6 is erected.

The inner box has a storage chamber 8 with an open top surface formed therein, and is provided with a meandering cooling pipe 9 on its outer surface, and is a plate-shaped cooler having a meandering refrigerant pipe 10a connected to the cooling pipe. 10 is placed in the center and the storage room is divided into two.
The storage chamber 8 is cooled by the cooling pipe and the plate-shaped cooler.

11.12 are convex parts formed on both side walls 2C of the inner box and the upper end of the plate-shaped cooler, projecting upward from the front wall 2a and back wall 2b of the inner box, and forming curved parts 13 at both corners. are doing.

14 is a machine room formed in the lower part of the main body, which includes a compressor 15 that constitutes a refrigeration cycle together with the cooling pipe and the plate cooler;
A condenser 16 and a blower 17 are housed therein.

Reference numerals 18 and 19 denote rails formed on decorative frames 20 provided oppositely to each other at the upper portions of both side walls, each of which has the same curvature and is configured at different levels above and below, and a transparent door body 21 having the same curvature as the rails. , 22 are slidably disposed on the respective rails so that products can be stored and taken out from the front and back of the main body.

Reference numeral 23 denotes a transparent fixing plate provided at the upper center of the rail, and a door storage section 24 is formed at the bottom of this fixing plate in which both the door bodies are stacked one above the other and accommodated.

The cooling box body has transparent door bodies 21, 22 of the front and rear sliding type inclined at the top opening of the storage chamber 8, so that the interior of the storage chamber can be accessed from the front and back of the body through the door bodies 21, 22. The product can be seen through, the product can be stored and taken out from both sides of the main body without interfering with each other's operations, the opening area of the top opening can be increased, and the product can be stored and taken out quickly.

In addition, by cooling the upper volume of the storage chamber, which increases due to the inclination of the door bodies 21 and 22, with the inner box 2 and the convex portions 11 and 12 of the plate cooler 10, the area near the top opening, which is the highest temperature in the storage chamber, is reduced to a low temperature. can be maintained.

Therefore, the effective internal volume in the storage chamber can be increased and more products can be stored, and even if frost forms on the protrusions 11 and 12, the door bodies 21 and 22 are slanted. Opening and closing of the door body will not be hindered by frost formation.

In addition, by forming the curved portions 13 at the corners of both ends of the convex portions 11 and 12, a predetermined distance is maintained between both corners of the respective convex portions and the front portion of the door body, and frost formation at the corners prevents the door body 21, This prevents the opening and closing of the cooler 22 from being obstructed, and also prevents damage to hands and fingers at the upper corner of the plate cooler 10 when storing and taking out products.

As described above, the present invention has transparent fixing plates installed at both ends at the center of the highest parts of the left and right side walls of the heat insulating wall, which is the top opening, and partitioning the top opening into the front and back, and a transparent fixing plate installed in the front and rear directions of the top opening, respectively. Two transparent door bodies are arranged to be slidable and overlap the lower part of the transparent fixing plate when both doors are opened, and are inclined forward and downward, respectively, and the inner wall of the heat insulating wall has convex portions at the upper ends of both left and right sides. A cooling pipe is provided in a meandering manner in the formed inner box, and the cooling pipe is connected to the cooling pipe, and is arranged so as to divide the storage chamber into left and right parts. Since it is equipped with a plate-shaped cooler with a convex portion, it is possible to see through and store and take out products in the storage room from the front and back of the main unit. The display and sales functions can be improved by allowing the operation to be carried out without interfering with the operation, and the upper opening is divided into front and rear sections with a transparent fixed plate, and the two transparent door bodies that can be slid in the front and rear directions are arranged so that they can be moved forward and backward. By arranging them so that they are tilted downward, the upper volume of the storage chamber can be increased, and
By extending the left and right side walls of the inner box and both convex portions of the plate-shaped cooler upward, the area near the top opening where the temperature of the storage chamber is highest can be maintained at a low temperature.
