Description

[Detailed explanation of the idea] (Industrial application field) The present invention relates to a cold storage chamber of a freezer.

(Prior art) When shipping frozen foods stored in a freezer, the frozen foods are first transported to a platform in front of the freezer and then loaded onto a frozen transporter. It takes a considerable amount of time, and during this time, the freshness of the frozen food may deteriorate and the quality may deteriorate.As a countermeasure, conventionally, the platform was covered with a vinyl sheet or the like to keep it cold.

(Problem to be solved by the invention) However, simple shielding with a vinyl sheet or the like cannot be expected to have much of a cooling effect, and an improvement has been desired.

In view of the above-mentioned circumstances, the present invention aims to provide a cold storage chamber of a freezer that can be expected to have a sufficient cold storage effect.

(Means for Solving the Problems) In the present invention, a cold storage chamber is formed on a platform in front of the freezer by extending both side walls and the ceiling of the freezer, and an accordion door type cold storage curtain is installed at the front opening of the cold storage chamber. In order to achieve the above-mentioned purpose, curtain-shaped auxiliary curtains are hung on both the inside and outside of the cold insulation curtain at appropriate intervals.

(Embodiment) In the drawings showing an embodiment of the present invention, 1 is a freezer for storing frozen foods, and 2 is a double door that opens and closes the front opening of the freezer 1.

In the illustrated embodiment, three freezers 1 are installed side by side, and a cold storage compartment 4 is provided on a platform 3 in front of them. It is an extension of that of .

A box-shaped hanging rail 10 with a groove-shaped notch 9 in the lower center is attached along the upper edge of the front opening of the cold storage room 4 (inside the tip 8 of the ceiling 7). Accordion from rail 10
A door-type cold insulation curtain 11 is hung.

The cold insulation curtain 11 is constructed of a plurality of rod rods 13 suspended from running wheels 12 within a hanging rail 10.
and a heat insulating board 15 whose both ends are rotatably attached to adjacent rods 13, 13 and whose central part is bendable with a hinge 14.
is formed by sandwiching a heat insulating foam material between the inner and outer curtains to enhance the heat insulation effect.

In order to enhance the sealing effect at both the upper and lower ends of the cold insulation curtain 11, guide spacers 16 are provided on the inner surface of the ceiling section 7 in front of the hanging rail 10, and rubber sealing materials are provided at both the upper and lower ends of the heat insulating board 15.
7, 18 and reinforcing plates 19, 20 are attached, respectively.

Reference numerals 21 and 22 indicate auxiliary curtains hung with appropriate gaps 23 and 24 on both sides of the upper part of the cold insulation curtain 11, and these auxiliary curtains have a shielding effect and a heat insulating effect of the air layer in the gaps 23 and 24. This plays the role of preventing cold air from flowing out and hot air from flowing in through the gap above the cold insulation curtain 11, but the outer auxiliary curtain 21 also serves as a seal when loading shipped products into the refrigerated transport vehicle 25. Fulfill.

(Effect of the invention) Since the cold storage chamber of the freezer of the invention is as described above, it can be expected to have a sufficient cold storage effect and can reliably fulfill its function.
