Abstract

PURPOSE:To prevent freezing of water and the occurrence of bedewing at the front of a guide part by providing a partition body entering a chamber and rotated along with closing operation of a first door, and a heat conduction body making contact with a part of the inner surface side of a guide part and a part of a radiation pipe for preventing sweating located on the inner side of the edge part of an opening and transmitting the heat of the radiation pipe to the guide part. CONSTITUTION:A heat conduction body 23 is located so as to make contact with a radiation pipe 15 and an inner surface 8B of a guide part, and the heat conduction part 23 performs a role to transfer the heat of the radiation pipe 15 to a guide part 8. Thereby, an upper part surface 8D and a front part surface 8C are heated. Since the guide part 8 is heated by the heat of the radiation pipe 15 through the heat conduction body 23, even when temperature in a chamber is low (0 deg.C or less), water 24 entering a gap between the guide part 8 and a molded product 10 forming a partition body 9 and having a semicircular groove is prevented from freezing, and dewing is prevented from occurring to a surface 8C, on the outside of a chamber, of the guide part.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is directed to the opening of a heat insulating box by means of a double door.
The present invention relates to a double door device that opens and closes and is equipped with a gasket for sealing on the back side of each door.

2. Description of the Related Art Conventionally, this type of door device has a structure as shown in FIGS. 2 to 5, such as the NR-F40VP1 released in March 1000.

1 is the refrigerator body, 2 is an outer box made of iron plate, and 3 is an inner box made of synthetic resin. 4 is a foam insulation material filled between the outer box 2 and the inner box 3, and the insulation box body 5 has an opening on the front side.
is formed. eA.

Reference numeral 6B denotes two double-sided double doors rotatably attached by upper and lower hinges 7A and 7B provided on the upper and lower sides of the left and right edges of the heat insulating box body 5. Reference numeral 8 refers to guide portions located on the non-attached side of each of the doors 6A and 6B, and installed oppositely above and below the edge of the opening 5A of the heat insulating box 6. This guide part 8
The front surface of the vehicle is planar and has an opening 5A and a road surface. 8A is a protrusion of the guide portion, and 9 is a partition. Reference numeral 10 denotes a molded product made of synthetic resin and having a semicircular groove constituting the partition body 9, and 11 denotes a back cover constituting the back side of the partition body 9. Reference numeral 12 designates a front decorative plate constituting the front part of the partition body 9, 13 a sweat prevention heater, and 14 a heat insulating material. When the door 6A is closed, the partition 9 rotates freely as the projection 8A of the guide portion 8 comes into contact with the inner surface of the molded product 10 having a semicircular groove. 15 is a heat dissipation pipe for preventing perspiration provided inside the edge of the opening 6A, 16 is a decorative plate forming the edge of the opening 5A, and 17 is a frame forming the edge of the opening 5A. 18 is a heat insulating material. 19 is door e
Gaskets attached to the peripheral edges of the back surfaces of A and eE, 20 are inside the refrigerator, and 21 are located inside the gasket 19 located on the non-attached side of the back surface of the door 6A, in two places, upper and lower, toward the interior of the refrigerator 20. A protruding support arm.

Problems to be Solved by the Invention However, with the above conventional configuration, if the temperature inside the refrigerator is kept low (below OT), if water gets into the gap between the guide and the partition, it will freeze, and the door will not open or the front of the guide will close. It had the disadvantage that dew formed on the parts.

The present invention solves the above-mentioned conventional problems and provides a door device for a refrigerator-freezer that can prevent freezing and dew condensation.

Means for Solving the Problems In order to solve the above problems, the large double door of the present invention has the following features:
A part of the inner surface of a guide part that rotates a rotatably attached partition that extends in the direction of the rotation axis of the door with a length that spans the rear opening edge of the non-attached part of the first door, and a heat insulating box. The heat conductor contacts a part of the heat radiation pipe for preventing perspiration provided inside the opening periphery of the guide part, and transmits the heat of the heat radiation pipe to the guide part.

Effect: With the above configuration, even if water enters the gap between the guide part and the partition, the guide part is warmed by transmitting the heat from the radiation pipe to the guide part via the heat conductor. ,
Water hardly freezes, and no dew condensation occurs on the front surface of the guide portion.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG. In addition, the same reference numerals are given to the same configurations as in the prior art, and detailed explanation thereof will be omitted.

22 is a frame having a hole 22A, which is an opening 5A of the heat insulating box 6.
It forms the periphery of the. 23 is a heat conductor installed so as to be in contact with the heat dissipation pipe 16 and the guide portion inner surface 8B. 8C is the outside surface of the guide section. 8D is the upper surface of the guide portion. Further, 24 is water that has entered the gap between the guide portion 8 and the molded product 1Q having a semicircular groove constituting the partition body 9.

The heat conductor 22 serves to transfer the heat of the heat radiation pipe 15 to the guide portion 8. Therefore, the upper surface 8 of the guide part 8
D and the front surface 8C are heated.

As described above, according to this embodiment, the guide part 8 is warmed by the heat of the heat radiation pipe 16 via the heat conductor 23, so even if the temperature inside the refrigerator 19 is low (below 0°C) It is possible to prevent the water 24 that has entered the gap between the guide part 8 and the molded product 1o having a semicircular groove constituting the partition body 9 from freezing, and to prevent dew condensation on the outside surface 8C of the guide part. can be prevented.

Effects of the Invention As described above, the present invention provides a heat insulating box body having a heat insulating box having an opening, and a heat insulating box body having a heat insulating box, which is provided at the back surface peripheral edge of the first and second doors which are rotatably attached to both sides of the opening so as to close the opening. a gasket that contacts the peripheral edge of the opening; a guide part located on the non-attached side of both doors and installed on the edge of the opening;
The back surface of the non-attached side portion of the first door extends in the direction of the rotation axis of the door and is rotatably attached to the opening edge, and when the first door closes, the storage a partition body that enters the interior and rotates in contact with the guide part, a part of the inner surface of the guide part, and a part of the heat dissipation pipe for preventing perspiration provided inside the opening periphery; Since it is composed of a heat conductor that transfers the heat of the heat dissipation pipe to the guide section, even if water enters the gap between the guide section and the partition section, the water will not freeze, and the storage of the guide section will not occur. There will be no dew on the outside surface.
