Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a door device for a refrigerator in which the opening of a heat insulating box is opened and closed by double doors, and each door is provided with a gasket for sealing on the back side of the door. .

Conventional technology Conventionally, this kind of door has been closed since March 1990.NR-
The F40VP1 (7) had a configuration as shown in Figures 7 and 8.

1 is the refrigerator body, 2 is an outer box made of iron plate, 3 is an inner box made of molded synthetic resin, 4 is a foam insulation material filled between the outer box 2 and the inner box 3, and 5 is an opening in the front. 6A is the opening of the insulation box 5, and eA and eB are two double-sided openings rotatably supported by upper and lower hinges 7A and 7B provided on the upper and lower left and right edges of the insulation box 5. The door 8 is a guide portion that is formed to protrude oppositely above and below the edge of the opening 5A of the heat insulating box 5 on the non-pivot side of each of the doors eA and eB, and the front surface of the guide portion 8. is the Sekiguchi 5A and the road surface in plan view. 8A is the protrusion of the guide part, 9 is the partition body, 1o
11 is a semicircular groove provided in the partition, 11 is a gasket as a sealing member with a magnet inserted into the periphery of the back surface of doors eA and eB, 12 is inside the refrigerator, and 13 is located on the non-pivot side of the back surface of door 6A. This is a support arm that protrudes in three directions, upper and lower, toward the interior of the warehouse at a portion located inside the gasket 11.

The operation of the refrigerator configured as above will be explained below. .

When closing the two double doors eA and eB, the partition 9 extends in the direction of the rotation axis of the door on the back surface of the non-pivot side of the first door 6A with a length spanning the opening edge and rotates. It is freely supported and when the first door 6A is closed, it enters the refrigerator interior 12, and the protrusion 8A of the guide part 8 and the semicircular groove part 1o provided in the partition body 9 come into contact and rotate. When the partition body 9 matches the semicircular groove 10, the partition body 9
The front surface is between the opening 5A of the heat insulating box 5 and the road surface, and the gaskets 11 on the non-pivot sides of both doors abut against the front surface of the partition 10 to maintain airtightness inside the refrigerator.

Problems to be Solved by the Invention However, in the conventional configuration described above, when the temperature inside the refrigerator is set to a low temperature, the semicircular groove provided in the partition that comes into contact with the protrusion of the guide part freezes or condenses, causing heat generation. Although it is conceivable to provide a body on the lower surface of the guide portion projection, it is considered that this has the disadvantage that heat is difficult to be transmitted from the heating element to the tip of the guide portion projection.

The present invention is intended to solve the above-mentioned problems, and it is an object of the present invention to provide a door device for a refrigerator-freezer that can efficiently transmit heat to the protrusion of a guide portion and also serve as a fixing device for a heating element.

Means for Solving the Problems In order to solve the above problems, the refrigerator/freezer door device of the present invention utilizes heat from a heating element provided inside the guide part by inserting a screw or a heating element mounting plate into the inside of the projection of the guide part. The structure allows the heating element to be attached to the

Effects of the present invention With the above-described configuration, the heat of the heating element can be efficiently transmitted to the protrusion of the guide part, so when the temperature inside the semicircular groove provided in the partition plate is set to a low temperature, The semicircular groove provided in the partition plate that comes into contact with the protrusion can prevent freezing or dew condensation, and the amount of heat from the heating element provided in the guide portion can also be reduced, thereby reducing electricity consumption. It can also serve as a heating element attachment.

EXAMPLE An example of the present invention will be described below with reference to the drawings. It should be noted that the same parts as those in the prior art are designated by the same reference numerals and the description thereof will be omitted.

The figure is a perspective view of the guide part in one embodiment of the present invention.
The figure is a sectional view taken from the B-B direction in Fig. 2, Fig. 4 is a perspective view of the refrigerator-freezer, Fig. 6 is a front view of the insulation box, and Fig. 6 is a sectional view taken from the A-A direction. It shows. 14 is door 6
Decorative plates of guide portions are formed oppositely above and below the edge of the opening 5A of the heat insulating box 6 in the portions A and 6B located on the non-pivot side, respectively. The guide part is facing towards the camera. Reference numeral 8A denotes a protrusion projecting from the guide portions 8 facing each other in the upper and lower directions of the opening 5A. Guide portions 8 are provided at the upper and lower ends of the partition body 9, which extends vertically with a length slightly smaller than the vertical dimension of the opening 6A, and has a flat front surface and curved corners at the rear surface. A semicircular groove 10 that slidably fits into the protrusion 8A
It is.

16 is a heating element attached to the guide part, 17 is a heating element 16
This is a screw that is attached to a mounting hole 8B provided in a protrusion 8A of the guide portion 8.

The operation of the refrigerator-freezer configured as above will be explained below.

By fixing the heating element 16 or the heating element mounting plate into the hole 8B in the projection 8A of the guide part 8 with a screw having good heat conductivity, the heat of the heating element 16 can be efficiently transferred to the guide part projection 8A. Heating can be performed.

As described above, according to this embodiment, since the heating element is installed inside the guide part, when the set temperature inside the refrigerator is low, the contact part between the protrusion and the semicircular groove can be frozen more efficiently. can be prevented.

Effects of the Invention As described above, the present invention provides the first stage of the Kannon opening ceremony. A refrigerator-freezer with a second door can realize a refrigerator-freezer with lower power consumption by improving the heating element mounting structure to prevent freezing and condensation in the semicircular groove provided in the partition and the guide part of the refrigerator-freezer with a second door. It is.
