Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a door device used in a drawer section of a refrigerator, such as a vegetable container.

[Conventional technology]

Figure 1 is a perspective view of a conventional refrigerator drawer door device similar to that shown in Japanese Utility Model Application No. 56-151892, and Figure 2 is an enlarged horizontal sectional view taken along the - line in Figure 1. be. In FIGS. 1 and 2, reference numeral 1 indicates a door frame made of extruded plastic, and the door frame 1 constitutes four sides of the outer periphery of the door body. Reference numeral 2 designates a front panel, and this panel 2 is fixed to the door frame 1 by fitting its peripheral edge into a groove of a flange 1a formed at the front of the door frame 1. Reference numeral 3 denotes a door reinforcing iron plate installed on the inner circumference of the flange 1b formed at the rear of the door frame 1. 4 is a heat insulating material that is foamed by injecting a urethane foaming solution after the door frame 1, front panel 2, and door reinforcing steel plate 3 are set; It is filled between the gaps and inside the door frame 1, and is thicker at the center than at the outer periphery. Reference numeral 5 denotes a door inner plate which is made of a vacuum-formed plastic plate and has a bank portion 5a.The door inner plate 5 is integrally attached to the frame 7 with screws 6 when attaching the frame 7 to the door frame 1. They are fastened together to the flange 1b, and the door reinforcing iron plate 3 and the heat insulating material 4 are covered with the door inner plate 5. Reference numeral 8 denotes a door seal made of an extruded product of soft plastic, and the door seal 8 has a protrusion 8a that is press-fitted into a hole provided in the flange 1b of the door frame 1, and is attached to the door frame 1, and when the door body is closed. It is configured to come into pressure contact with the front flange of the inner box 11 of the refrigerator main body.

The conventional refrigerator drawer door device configured as described above has a bank portion 5a on the inner door plate 5 of the door body to prevent the cold air inside the refrigerator from leaking to the outside or to prevent the cold air from leaking to the outside. In order to prevent heat exchange, the distance between the side surface of the inner box 11 of the refrigerator body and the outer periphery of the door inner plate 5 is narrowed.

[The problem that the idea aims to solve]

The conventional refrigerator drawer door device is constructed as described above, and since the door inner plate 5 having the bank portion 5a is manufactured by vacuum forming a plastic plate, it takes a long time to manufacture and is also disadvantageous. However, there was a problem in that the mold was expensive, and therefore the door body was also expensive.

Then, it would be sufficient to make the inner door plate flat.In fact, conventional refrigerators with flat inner door plates are shown in, for example, Japanese Utility Model Application Publication No. 55-54885. If the bank part 5a is eliminated and the door inner plate is made into a flat plate, there is a drawback that the cold air inside the refrigerator tends to leak to the outside.

[Means to solve the problem]

This invention was made in order to eliminate the above-mentioned drawbacks of the conventional method, and it consists of a door frame, a front panel whose peripheral part is fitted and fixed to the front part of the door frame, and a flange installed at the rear of the door frame. The iron plate for reinforcing the door, which is filled between the panel and the iron plate for door reinforcing, and inside the door frame, and is thicker in the center than the outer periphery, and the inside of the refrigerator body is fixed to the flange of the door frame. In a refrigerator drawer door device comprising a door body having a door gasket that presses against a front flange of a box and a flat inner door plate provided on the rear surface of the door reinforcing steel plate, a fin portion provided on the door gasket. The inner box has a thickness such that it covers the rear surface of the outer peripheral part of the inner door plate, and the front flange of the inner box completely covers the fin. Provide equipment.

[Effect]

This idea is such that even if the door inner plate is a flat plate, the fin provided on the door seal covers the rear surface of the outer periphery of the door inner plate, and the front flange of the inner box completely covers the fin. The thickness of the inner box reduces leakage of cold air inside the refrigerator to the outside.

〔Example〕

An embodiment of this invention will be described below with reference to FIG.

FIG. 3 is a sectional view corresponding to FIG. 2. Third
In the figure, numerals 1 to 8 indicate the same or equivalent parts as those with the same numerals in FIGS. is extended in the outer circumferential direction to the position where the conventional door inner plate was. Further, 10 is a door inner plate made of a flat plate, 8b is a fin part integrally provided at the rear of the door seal 8, and the fin part 8b is the door inner plate 1.
The outer peripheral part 10a is brought into contact with the rear surface of the outer peripheral part 10a of
is covered. Reference numeral 12 denotes a front flange provided on the inner box 11 of the refrigerator body. This flange 12 has a large width, so that when the door body is closed, the outer periphery 10a of the door inner plate 10 is attached to the gasket 8 in front of the inner periphery of the flange 12.
The front flange 12 has a thickness of the inner box 11 such that it completely covers the fin part 8b. . The configuration of this embodiment other than that described above is the same as that of the conventional one shown in FIGS. 1 and 2.

[Effect of idea]

As explained above, this invention consists of a door frame 1 and a front panel 2 whose peripheral portion is fitted and fixed to the front part of the door frame 1.
, a door reinforcing iron plate 3 installed on the flange 1b at the rear of the door frame 1, and a heat insulating material 4 filled between the panel 2 and the door reinforcing iron plate 3 and inside the door frame 1, the center of which is thicker than the outer circumference. The front flange 1 of the inner box 11 of the refrigerator body is fixed to the flange 1b of the door frame 1.
In a refrigerator drawer door device comprising a door body having a door packing 8 that presses into contact with the door packing 8 and a flat door inner plate 10 provided on the rear surface of the door reinforcing iron plate, the fin portion provided on the door packing 8 is provided. 8b
covers the rear surface of the outer peripheral part 10a of the door inner plate 10, and
The front flange 12 of the inner box 11 is connected to the fin portion 8.
The following effects can be obtained by having the thickness of the inner box so as to completely cover the inner box.

That is, since the door inner plate 10 is made into a flat plate,
Door inner panels can be obtained in a shorter time and at a lower cost than conventional vacuum-formed products. Moreover, since the fin part 8b of the door seal 8 covers the rear surface of the outer peripheral part 10a of the door inner plate 10, there is no fear of dust entering between the door seal 8 and the heat insulating bank part 9, resulting in cleanliness. Furthermore, the front flange 12 of the inner box 11 is connected to the fin portion 8b.
Since the thickness of the inner box is such that it completely covers the inner box, it is difficult for the cold air inside the refrigerator to escape to the outside, and a seal that is equal to or better than that of conventional products can be achieved. Therefore, according to this invention, by making the door inner plate 10 a flat plate, it can be made inexpensive, clean, and has a sealing performance equal to or better than conventional ones, and is inexpensive. To obtain a door device for a refrigerator drawer part that has good performance despite its small size.
