Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to an improvement of a refrigerator door frame composed of a heat-insulating ceiling panel, floor panel, side wall panel, etc.

[Conventional technology]

In general, this type of refrigerator consists of a ceiling, a floor, and a side wall by fitting connecting grooves and protrusions provided at the connecting ends of the heat insulating panels into each other. As shown in Fig. 8, a dedicated framed wall panel f is placed in an opening e formed by a ceiling panel a, a floor panel b, and side wall panels c and d on both sides.
was incorporated, and a door panel h was attached to the storage opening g formed in this framed wall panel f so as to be openable and closable.

[The problem that the idea attempts to solve]

As shown in FIG. 9, the conventional framed wall panel f has a wooden frame j attached to the opening inner surface of the panel body i of the framed wall panel f, and a bolt k passing through this wooden frame j. Since a wooden storage door frame with an L-shaped cross-section and a face frame is attached, the structure is complicated and heavy, causing problems in transportation and inventory management. Processing and special jigs are required, there is a risk of dimensional deviations, and the insulation properties are not fully satisfactory.

In addition to the above, as shown in Fig. 10, a cross-sectional frame member p is attached to the inner surface of the opening of the framed wall panel f, and a heat insulating material m such as foamed urethane is placed inside in the same way as the wall panel c in the shape of a sandwich. A type of wall panel f with a pre-formed storage door panel n has also been used, but this type of wall panel f also has problems such as the need for a complicated panel forming method.

[Means to solve the problem]

This invention was made with the intention of solving the above-mentioned problem, and is a refrigerator door frame used for a refrigerator door opening formed by a ceiling panel, a floor panel, and side wall panels on both sides. A concave strip is provided on the long side contact surface of the storage opening frame body made of a synthetic resin foam material having an L-shaped cross section and having a long side and a short side that contact the outer edge of each side of the opening and the long side and short side, respectively, which contact the opening surface, 4
A connecting fitting is housed and connected between the grooves of the corner portions of the frame bodies, and a panel forming the opening is provided on the contact surface on the short side of each frame body. A recessed groove portion into which a connecting convex strip of the panel can be fitted is formed, and a fitting material capable of fitting with the connecting concave strip of the abutting panel is selectively attached in the recessed groove portion. This is a proposal for a mouth frame.

[Effect]

That is, this invention does not require a dedicated wall panel with a door frame, and the door can be easily formed at a desired position of the refrigerator using a single type of simplified frame material.

d, and a fitting member 14 that is selectively attached to the storage door frame main body 12 according to the shape of the connecting end of each panel 2, 3, 4 at the storage door opening. In this case, as shown in FIGS. 2 to 4, the storage opening frame main body 12 has a long side 1 that comes into contact with the outer edge of the storage opening.
2a, and a short side 12b that comes into contact with the opening surface of the edge of the storage opening. A groove 15 is provided on the panel abutting surface of the panel, and a groove 16 into which the connecting protrusion 11 of the panel can be fitted is formed on the panel abutting surface of the short side 12b. In this case, the mounting washer 18 of the latch receiver 17 or the hinge receiver washer is housed in the concave portion 15, and the L-shaped connecting fittings 13a, 13b, 13 are housed on the corner side.
c and 13d are accommodated (see Figure 3).

In the above embodiment, the L-shaped connecting fitting 13a on one side,
13b is also used as a hinge receiving washer, but of course the hinge receiving washer is also used as the L-shaped connecting metal fitting 13.
It may be provided separately from a and 13b.

A door 6 is provided on the outer surface of the long side of the storage door frame main body 12.
A shallow concave packing receptacle 20 is formed to receive the packing 19 along the periphery of the packing receptacle. Note that a mounting groove 22 for the decorative sheet 21 is formed at another location on the outer surface on the long side, and a notch 24 for filling the caulking material 23 is formed at the end of the long side contact surface. There is.

On the other hand, the fitting material 14, as shown in FIG.
The trapezoidal half portions 14a and 14b are placed back to back, and one of the trapezoidal half portions 14a is fitted into the recessed groove portion 16 of the storage opening frame main body 12 and fixed with screws or adhesive. , the other trapezoidal half portion 14b is fitted into the connecting groove 10 of the abutting panel. In this case, the tip of the trapezoidal half portion 14b has a U that can fit into the connecting rib 10a protruding from the bottom of the connecting groove 10.
A shaped groove 14c is provided.

When installing the storage door frame 5 of this invention configured as described above, first connect the corner parts of each storage door frame main body 12 with the L-shaped connecting fittings 13a, 13b, 13c.
and 13d, and a latch receiver 17 is connected at a predetermined position of the concave portion 15 provided on the long side contact surface.
The mounting washer 18 and the hinge receiving washer are stored,
Depending on the shape of the connecting end of the side wall panel 4 of the adjacent storage opening, a trapezoidal fitting member 14 is inserted into the groove 16 of either the left or right storage opening frame body 12 that comes into contact with the connecting groove 10. After the half portions 14a are fitted and fixed, they are placed in the storage opening in the same manner as the side wall panels 4, etc., and the installation work is performed.

As explained above, according to the storage door frame of this invention, the storage door frame main body, which is attached to the edge of the storage door opening formed in the refrigerator, is attached to the outer surface of the edge of each side of the opening and the opening surface. It is formed into an L-shaped cross section made of a synthetic resin foam material having long sides and short sides that come into contact with each other, and a grooved portion is provided on the contact surface on the long side of the storage opening frame body, and each of the four frame bodies Connecting fittings are housed and connected between the grooves of the corner portions, and protrusions for connecting the panels forming the openings are provided on the contact surfaces of the short sides of each frame body. Since the fitting material that can be fitted is selectively attached, the following effects can be obtained.

That is, 1. Since it is composed of one type of storage opening frame main body, it is easy to improve the manufacturing aspect of the component parts and to manage inventory.

2. Since the entrance frame for the entrance frame has the same insulation performance as conventional insulation panels, there is no need for the conventional framed wall panels dedicated to special openings, and the number of types of panels is reduced, making it easier to process. becomes easier.

3. Since it can be built in the same way as the panels that make up a refrigerator, construction can be done easily and quickly.

4. Utilizing the connecting grooves or connecting protrusions formed on the panel, construction can be done according to the direction of these uneven lines, allowing for strong, accurate, and easy installation.

5. Attachment of accessory parts such as hinges and latches can be done more accurately and easily than in conventional insulation panels with foamed core material inside.
