Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a door structure for a refrigerator or the like in which a board for controlling the temperature of a storage compartment is provided on the door.

Conventional technology A conventional example will be explained based on FIG. 4. 1 is a door frame having a substantially U-shaped cross section, 2 is an outer panel of the door, 3 is a board for controlling the temperature control of the storage room, and 4 is the board. 3 is a decorative panel that covers the front surface of 3 and displays operating instructions, 6 is a box with an opening on one side and has a flange around the entire circumference, 6 is an inner panel of the door, and 7 is an outer panel of the door. 2. A heat insulating material such as urethane foam is filled between the door inner plate 6 and the door frame 1 having a substantially U-shaped cross section.

Further, the wall thickness of the insulation material is 5 dimensions at the part of the box body 6,
Other parts have 6 dimensions.

Problems to be Solved by the Invention However, with the above configuration, if the board 3 for controlling the temperature of the storage room is disposed close to the door frame 1 having a substantially U-shaped cross section, foaming may occur. There is a problem in that the wall thickness of the heat insulating material 7, such as urethane foam, becomes thinner locally, such as from 6 dimensions to 5 dimensions, and dew condensation occurs on the inner surface of the box body 5 in which the substrate 3 is disposed. To solve the problem, remove the door outer panel 2.
The method of increasing the contact area of the flange portion of the box 5 to ensure sufficient heat conduction was also not able to be implemented satisfactorily.

Also, for assembly, the door frame 1 having a substantially U-shaped cross section and the box body 6
It is difficult to seal the area where the flanges are adjacent to each other, and leakage of the heat insulating material 7, such as urethane foam, has also arisen as a practical problem. Due to the above problem, the degree of freedom was restricted as a design constraint.

SUMMARY OF THE INVENTION In view of the above drawbacks, it is an object of the present invention to provide a door for a refrigerator or the like that is easy to assemble and eliminates problems such as condensation.

Means for Solving the Problems In order to achieve the above object, the present invention provides a box body which is opened on one side and has a flange around the entire circumference, in which a board for controlling the temperature control of a storage room, etc. is disposed inside; The door is configured such that the outer plate of the door can be held at the same time in the gap between the first and second flanges by providing a fin of a soft member at the tip of the second flange of the door frame having a substantially U-shaped cross section. be.

With the above-described configuration, the present invention makes it possible to secure a sufficient contact area between the door outer panel and the box body in which a board for controlling the temperature control of the storage room is disposed, and the inner surface of the box body. In addition to preventing dew condensation, it can also provide stable sealing properties for heat insulating materials such as urethane foam.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 3. 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. 8 is a door frame with a U-shaped cross section,
One end has a first flange 8a and a second flange 8b on the door outer plate 2 side.

Here, a fin 8C is formed at the tip of the second flange 8b using a soft material such as soft vinyl chloride.

In addition, the gap between the first flange 8a and the second flange 8b is approximately equal to the thickness of the door outer panel 2 at the fin 80 at the tip, and the temperature control between the door outer panel 2 and the storage room is controlled at the base. A gap equal to the sum of the plate thicknesses of a box body 5 having an opening on one side and having a flange around the entire circumference is formed, in which a board 3 for carrying is disposed. A holding portion for holding the door inner plate θ is formed at the other end of the door frame 8.

Here, if the door outer plate 2 is inserted into the gap between the first seventh flange 8a and the second flange 8b of the door frame 8 having a substantially U-shaped cross section, the soft vinyl chloride etc. formed at the tip of the second flange 8b will be removed. The fins 8C of the soft member completely adhere to each other. Further, the flanges of the box body 6 can be easily inserted into the first flange 8a and the second flange 8b of the door frame 8 without any special processing on the door frame 8, and can be inserted into any position. It is possible to install the and the door outer plate 2 and the door frame 8,
A foamed heat insulating material 7 is filled between the door inner plate 6 and the above-mentioned king is fixed.

With the above configuration, the box body 6 can be attached to the door outer panel 2.
A sufficient contact area is ensured in the seven lunges around the entire circumference, heat conduction due to outside temperature is sufficiently conducted from the door outer panel 2, and internal dew condensation can be prevented despite the thin insulation wall thickness. be. Furthermore, since the box body 5 can be placed in any position, it has extremely high versatility and a large degree of freedom in design. In addition, in the door frame 8 having a substantially U-shaped cross section, the door outer panel 2 and the box body 6
Therefore, stable sealing performance of the heat insulating material 7 such as urethane foam can be easily realized.

Effects of the Invention As described above, the present invention has a box body with a board for controlling the temperature of a storage room, etc. inside, an opening on one side, and seven flange around the entire circumference, and a door outer panel with a cross section of approximately A fin of a soft member is provided at the tip of the second flange of the U-shaped door frame, and the door is constructed so that it can be held simultaneously in the gap between the first and second seven lunges. A sufficient contact area is secured between the door outer panel and the flange around the entire circumference, heat from the outside temperature is sufficiently conducted from the door outer panel, and internal condensation can be prevented despite the thin insulation wall thickness. , which can eliminate design constraints and provide stable quality. Furthermore, regarding the sealing performance of a heat insulating material such as urethane foam, it is possible to achieve a stable sealing performance that is easy to assemble.
