れる。 FIG. 4 is a partial cross-sectional view taken along the line in FIG. 3 of the conventional refrigerator door disclosed in Japanese Utility Model Publication No. 60-39742. As shown in FIG. 4, this heat-insulating door is constructed by foam-filling a heat insulating material 5 into a space formed by a frame member 3 and a door outer panel 4, and then adding a door inner panel and a gasket (both not shown). It is configured to be fixed to the frame member 3. The frame member 3 is made of an extrusion molded product of synthetic resin, and is a decorative frame 3 that forms the outer peripheral surface of the heat insulating door 2.
A pair of clamping pieces 3b that fit and hold the outer periphery of the door outer plate 4 are protruded perpendicularly to the decorative frame 3a in the inner peripheral direction of the front edge of the decorative frame 3a, and the gasket and the door are inserted in the inner peripheral direction of the rear edge of the decorative frame 3a. Mounting piece 3 that fixes the outer periphery of the inner plate
c protrudes at right angles to the decorative frame 3a, and is formed into a substantially U-shaped cross section. The frame member 3 includes a clamping piece 3
V-shaped notches are provided at appropriate locations on the mounting piece 3b and the mounting piece 3c, and the parts with these notches are bent at right angles to form a rectangular frame. The outer periphery of the plate 4 is inserted and held.

果を高めることもできる。 The so-called frame-shaped heat insulating door 2 in which the outer periphery of the flat door plate 4 is surrounded by the frame member 3 can be made by changing the color tone of the door plate 4 and the frame member 3.
It improves the design and increases the product value. Also,
As shown in FIG. 5, a design film 3 such as an aluminum vapor-deposited film is placed on the front surface of the front holding piece 3b.
The design effect can be further enhanced by thermally welding d or by changing the color tone between the front clamping piece 3b and the decorative frame 3a.

同様である。 Further, as shown in FIG. 6, one clamping piece 3e
A frame member 3 having a substantially L-shaped cross section is formed on the inner peripheral side of the decorative frame 3a in parallel thereto, and a peripheral wall 4b protruding from the face plate portion 4a at right angles to the rear side is formed by drawing or the like. and a peripheral wall 4 of the door outer panel 4.
A heat insulating door 2 is conceivable, in which the door 2b is fitted and held between the holding piece 3e and the decorative frame 3a. The structure of the heat insulating door shown in FIG. 6 other than that described above is the same as that shown in FIG. 4.

という問題点があつた。
The conventional refrigerator heat insulation door shown in FIGS. 4 and 5 has an enhanced design effect and good production efficiency on the production line.
Since it protrudes further to the front, dust and dirt tend to adhere to and accumulate at the joint between the door outer plate 4 located at the lower side of the heat-insulating door and the front clamping piece 3b, and it is difficult to clean. Furthermore, when water droplets adhere to the surface of the door outer panel 4, the water droplets stagnate near the joint and enter between the door outer panel 4 and the frame member 3, causing rust and corrosion of the door outer panel from the end surface. There was a problem that the design and commercial value were impaired.

点があつた。 The insulation door of the refrigerator shown in FIG.
This is considered to improve the cleanability and corrosion resistance of the door shown in Figs. It is difficult to make the peripheral wall 4b a flat surface, and when the insulation material 5 is foam-filled, a part of the insulation material 5 leaks from the joint between the peripheral wall 4b and the frame member 3, which impedes productivity. It was hot.

に冷蔵庫本体に枢支される。 In Figures 1 and 2, 4 is the outer panel of the door;
The door outer plate 4 has a flange 4d parallel to the face plate part 4a on the outer circumferential side of the face plate part 4a through a stepped part 4c having a height dimension (h) larger than the thickness dimension t of the clamping piece 3b on the front side of the frame member 3. It is integrally formed around the circumference. Further, 3 is a frame member, and 5 is a heat insulating material, which are the same as those shown in FIG. The door outer panel 4 has a flange 4d inserted and held between a pair of supporting pieces 3b provided on the frame member 3, a face plate portion 4a protruding toward the front side of the clamping pieces 3b, and is joined to the frame member 3. A heat insulating material 5 is foamed and filled in the space formed by the door panel 3 and the door outer panel 4. Further, a gasket and a door inner plate (not shown) are fixed to the mounting piece 3c of the frame member 3 in the same manner as shown in FIG. The heat insulating door 2 of the embodiment constructed as described above is pivotally supported on the refrigerator body in the same manner as that shown in FIG.

る。 The heat insulation door 2 of the embodiment configured as described above and installed to cover the front opening of the refrigerator main body is as follows:
The face plate part 4a of the door outer plate 4 is located at the frontmost side, and the frame member 3 is retracted one step from the face plate part 4a, so that the joint between the door outer plate 4 and the frame member 3 at the lower side of the heat-insulating door Dust and dirt do not accumulate in the refrigerator, allowing you to keep it clean at all times. In addition, the stepped portion 4c of the door outer panel 4
touches the tip of the clamping piece 3b on the front side of the frame member 3, so even if water drops form on the face plate portion 4a of the door outer panel 4, no water droplets will enter between the door outer panel 4 and the frame member 2. Therefore, the door outer panel 4 is prevented from rusting.

ある。 In the above embodiment, a case has been described in which the door outer panel 4 is made of a drawn steel plate, but it is most effective to use a thermoformed synthetic resin sheet as the door outer panel in this invention. In other words, when drawing and forming a steel plate to form a step, the insulation door is required to have an excellent appearance in terms of design. It is necessary to use a plated mold to prevent scratches on the painted surface, which makes the mold expensive, and the drawing process tends to cause distortion on the door outer panel. Mechanisms such as wrinkle holders are large-scale, and the residual strain in the steel plate deforms the outer panel of the door during filling with insulation material and later assembling the insulation door, increasing manufacturing costs. but,
In this example, the step part is thermoformed using a synthetic resin sheet such as acrylic butadiene styrene (ABS) or polypropylene (PP) that is not affected by the urethane foam insulation material, and then cut to the dimensions of the door outer panel. It is advantageous to manufacture door panels by using a method that is inexpensive and provides stable door panels in terms of quality.

断熱扉が得られるという効果がある。
As explained above, according to this invention, a door outer plate in which a flange is formed parallel to a face plate part through a step part is used, and a pair of clamping members protruding the flange in the inner circumferential direction of a frame member is used. Since it is inserted and held between the two halves and the face plate part of the door outer panel is made to protrude to the front side of the frame member,
Dirt and dust will not accumulate at the joint between the door outer panel and frame member at the bottom of the insulated door, and even if water droplets adhere to the face plate, they will not enter between the door outer panel and frame member from the above joint. This makes it possible to keep the refrigerator clean, prevents rust even if the outer panel of the door is made of painted steel, and since the frame members can be seen from the front, the design is not compromised, and productivity is also relatively good. This has the effect of providing an inexpensive insulated door.
