Description

[Detailed description of the invention] This invention relates to a freezer that closes the opening on the top surface of the main body with a rotating door and a sliding lid. The aim is to prevent this and speed up the work of loading and unloading products.

An example of the present invention will be described below based on the drawings. 1 is a freezer called Chiest Freezer;
The main body is composed of an inner box 3 having an opening 2 for storing and taking out products on the top surface, an outer box 4 with an opening on the top surface, and a foam heat insulating material 5 filled between the inner and outer boxes. A meandering cooling pipe 6 is closely arranged on the outer surface of the main body, and a refrigerant compressor 8 and a condenser 9, which constitute a refrigeration cycle together with the cooling pipe, are installed in the machine room 7 at the bottom of the main body. The interior 10 of the refrigerator is also cooled with cold air that is cooled by the tube and undergoes natural convection. 11 is a ring-shaped packing 1 around the bottom surface.
A heat insulating door made of resin and provided with a heat insulating door 1a is fixed to the main body via vertically rotating hinges 12, 12, and closes the opening 2 from above the main body so as to be openable and closable. 13
A, 13B, and 13c are first to third step portions formed on the inner circumferential wall of the inner box 3, which is the circumferential surface of the opening, and both the first and second step portions 13A, 13B are made of aluminum or the like. Two lids 14A and 14B made of a material with low thermal emissivity are placed so as to be slidable in the lateral direction with their upper surfaces at different heights, and the third step 13c has a lid on both sides of the container 15 such as a basket. Stop portions 15a, 15
A is mounted on a rack so that it can be slid laterally. Both lids close the opening 2 in an openable and closable manner, and by sliding one lid, they overlap each other and open approximately half of the opening 2.

According to this configuration, when the door 11 is opened and closed with both the lids 14A and 14B closed and the opening 2 closed, the changes in wind pressure caused by the opening force and the closing force are reflected by the lids 14A and 14B. The information is not transmitted to the interior 10 of the refrigerator by blocking the information, and the information is not transmitted to the interior 10 of the refrigerator when the door 11 is opened or closed.
It is possible to prevent cold air from leaking from the refrigerator and outside air from entering the refrigerator interior 10, thereby preventing an extreme rise in the temperature inside the refrigerator.
When taking out the product from 0, there is no change in wind pressure due to opening and closing of the lids 14A and 14B, and the lid 14A
After placing the products to be stored in the refrigerator in advance, the lid is slid to open approximately half of the opening 2, and the products are placed inside the refrigerator 10.
The lids 14A, 14B can be used to store and take out a large number of products, such as storing or removing products from the warehouse interior 10 after opening approximately half of the opening 2 by sliding the lid 14A. One of the plates can be used as a product placement plate, allowing quick loading and unloading of products, and at the same time, shortening the opening time of the opening 2 and greatly reducing the amount of outside air entering into the refrigerator interior 10. can. Furthermore, both lids 14A are provided below the door 11,
14B, the door 11 can be made thinner and lighter in weight, and the hinge 1
2, 12 durability can be improved.

Furthermore, since the lids 14A and 14B are made of a material with a low thermal emissivity, they are not affected by the radiation cooling of cold air, but rather improve the cooling effect of the inside 10 by reflecting the cold air. Even if the temperature decreases due to cooling by heat conduction, the conductive heat is hardly radiated and transmitted in the vertical direction, and both lids 14A, 1
It is possible to prevent heat loss from inside the refrigerator 10 via 4B, and also to prevent dew condensation on the surface of the door 11.

As described above, the present invention includes a vertically rotating door that is fixed to the main body via a hinge and that can freely open and close an opening formed on the top surface of the main body from above the main body;
Two laterally sliding plates are placed on a step formed on the circumferential surface of the opening so that the height of the upper surface is different from each other, and by sliding one plate, approximately half of the opening can be freely opened and closed. Because it is characterized by a lid, the slidable lid prevents changes in wind pressure caused by door opening and closing forces from being transmitted to the inside of the refrigerator, and prevents cold air leakage and outside air when opening and closing the door. This prevents intrusion, allows for quick storage and removal of products, shortens the time the opening is open and reduces the temperature rise inside the refrigerator, and furthermore, the lid suppresses the transmission of cold air to the door. Therefore, the durability of the hinge can be improved by making the door thinner and lighter in weight.
