Description

[Detailed description of the invention] This invention relates to a freezer in which the opening for storing and taking out products formed on the top surface is closed with a slidable door. The objective is to reduce frost formation and to make this frost invisible from outside the refrigerator.

An embodiment of the present invention will be described below with reference to the drawings. 1 is a metal inner box 2 with an open top, an outer metal box 3 with an open top, and a decorative frame 4 made of resin in the shape of an opening that connects both the inner and outer boxes. In this freezer, the main body is made up of the foamed heat insulating material 5 filled in the space formed by the two boxes and the decorative frame, and the interior 6, which has both bottoms formed by the inner box, is connected to the inner box 2. The product is cooled by a meandering cooler 7 attached to the outside, and the product is stored and taken out through an opening 8 with both bottoms formed by the decorative frame.

Reference numeral 9 denotes a rail member provided around the inner side of the decorative frame, and is composed of an insertion part 9a formed by bending a metal plate, first and second sliding parts 9b and 9c, and an inclined part 9d. The insertion part 9a is inserted between the upper end of the metal reinforcing member 11 and the decorative frame 4, which are fastened together with the decorative frame 4 and inner box 2 using screws 10a and 10b, and the lower end of the reinforcing member 11 is tilted. By fixing the portion 9d with the screws 10c, it is attached so as to cover the upper end of the inner box 2 which is exposed to the interior 6 of the refrigerator at an appropriate distance from the inner box 2.

Reference numeral 12 denotes a dew-proof heater disposed closely on the back surface of the rail member 9.

Reference numerals 13A and 13B are slidable transparent doors whose ends are mounted on both the first and second sliding portions 9b and 9c of the rail member to open and close the opening.

14 is a reinforcing member 11 together with the inclined portion 9d of the rail member 9.
A metal support is fixed to the lower end of the metal support, and reference numeral 15 is a product storage container such as a basket whose upper edge is rested on this support.

According to this configuration, the rail member 9 on which the doors 13A and 13B are mounted is attached around the inner side of the decorative frame 4, and
Since the upper end of the inner box 2 that is exposed to the inner box 2 is separated from the inner box and covered, the rail member 9 prevents the outside air from entering the refrigerator interior 6 from the opening 8 when the door is opened until it comes into contact with the upper end of the inner box 2. During this time, the outside air is cooled by cold air, so there is no local frost formation on the top of the inner box 2, and the amount of frost on the top of the inner box 2 is small and uniform frost formation is achieved. It is possible,
Moreover, since frost is hardly visible from outside the refrigerator, it is possible to improve the product display effect.

Moreover, since the lower end of the rail member 9 is supported by the reinforcing member 11, even if the second sliding part 9c is separated from the inner box 2, it does not bend, and the transparent doors 13A and 13B can smoothly slide. Moreover, by heating the rail member 9 with the anti-condensation heater 12, dust on both the first and second sliding parts 9b and 9c can be prevented, and the transparent door 13A due to frost formation on the rail member 9 can be prevented. It is also possible to prevent the sliding movement of 13B from occurring.

As mentioned above, the present invention has a metal inner box with a cooler on the outside and an opening on the top that defines the inside of the refrigerator, an outer metal box with an opening on the top that houses this inner box, and a connection between the inner and outer boxes. A decorative frame made of resin defining an opening for storing and taking out products, and a metal frame whose upper end is fixed to the decorative frame and whose lower end is spaced from the upper end of the inner box exposed to the inside of the refrigerator. a reinforcing member and a first guiding member for guiding two transparent doors that slidably close the opening;
and a metal rail member that forms a second sliding part, has a lower end fixed to the reinforcing member, and covers an upper end exposed in the interior of the inner box, and a dew-proof heater provided on the rail member. The rear-facing box cools the outside air with the cold air by increasing the distance of the cold air that enters the refrigerator from the opening when the door is opened until it comes into contact with the upper end of the inner box using the rail member. By contacting the upper end of the inner box, the amount of frost formed on the upper end of the inner box is reduced and uniformly formed, thereby making it possible to avoid frosting due to extremely localized frost formation, and to prevent deterioration of the display effect due to frost.
In addition, even if the lower end of the rail member is separated from the inner box and faces the inside of the refrigerator, the mechanical strength of the rail member can be improved by the reinforcing member, and the frost buildup on the rail member can be prevented by using the dew prevention heater. As a result, bending and frost formation do not occur on the rail member, allowing smooth sliding of the transparent door.
