Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the installation of decorative panels on doors of freezers, refrigerators, etc. that are housed and installed in system kitchens or unit kitchens.

Conventional technology As shown in the West German patent DE-3426991C1, the structure for mounting decorative panels on the doors of freezers and refrigerators has been designed to match the colors, materials, and decorations of doors of system kitchens and other unit cabinets. In order to unify the walls, etc., consideration was given to fitting a decorative panel from the outside into the door body, which is filled with insulation material.

Hereinafter, a conventional door decorative panel mounting structure as described above will be described with reference to the drawings.

Figure 4 is a perspective view of a refrigerator for system kitchens equipped with a conventional door decorative panel mounting structure, Figure 6 is a cross-sectional view of the opening door decorative panel mounting structure, and Figure 6 is a longitudinal sectional view of the same. be. 1 is a refrigerator main body, 2 is a heat insulating door, 3 is a decorative board that matches the door of other system kitchen equipment, 4 is a main body, and a heat insulating material 7 is filled between an outer shell 6 and an inner plate 6.

A through hole 8 is provided in the main body 4, and a decorative plate 2 is provided around the through hole 8.
A stepped portion 1o is provided so that the head of a screw 9 for attaching the screw can fit therein.

The function of the door decorative panel mounting structure configured as described above will be explained below.

The doors of system kitchens, unit-type kitchen shelves, etc., and the doors of refrigerators, etc., primarily require insulation performance.

Therefore, in terms of appearance, it is made to match the decorative board 2 by using the same material and color as other system kitchen appliances, and the main body 4 filled with the heat insulating material 7 provides heat insulation performance. Further, the decorative panel 2 was fixed to the main body 4 by passing screws 9 through through holes 8 provided in the main body 4 from inside the refrigerator, and the internal plate 6 was arranged to cover the screws 9.

Problems to be Solved by the Invention However, in the above configuration, heat leaks through the screws due to the thickness of the decorative board and the location of the screws.
Condensation forms on the decorative board surface.

Also, when installing the decorative board (during on-site construction), it is difficult to set the decorative board onto the main body, and it is also difficult to drive screws from the back of the door, resulting in a long installation time and an impact on the total cost. This was also a major factor in increasing costs.

Moreover, the thickness of the decorative board and the allowance under the head of the screw cannot be secured, so the tip of the screw is exposed to the surface of the decorative board, or the insulation thickness of the screw part of the door body is thick enough to meet the specified dimensions, making it difficult to hook screws onto the decorative board. There were issues such as running out of money.

The present invention was made in view of the above problems, and has a simple structure that prevents dew condensation on the surface of the decorative board, and allows for quick installation.
To provide a door decorative panel mounting structure that can ensure appearance quality.

Means for Solving the Problems In order to solve the above problems, the door decorative panel mounting structure of the present invention provides upper and lower door caps on the main body of the door, and L-shaped fittings and single-shaped fittings are attached to the door decorative panel in advance. After installing, insert the 1-shaped metal fitting into the door cap groove and fix it to the door body from above with screws.

Function The present invention eliminates heat leakage through screws and dew condensation on the surface of the decorative board due to the above-described configuration.

In addition, the work of attaching the decorative board can be done easily, and the lack of attachment strength due to the lack of latching allowance for two screws can be sufficiently ensured.

Example An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

This will be explained with reference to FIG.

12 is on the door cap having the groove 11.

13 is a front door panel, and 14 is an inner plate, the inside of which is filled with a heat insulating material 16 to form a main body 16.

Reference numeral 19 denotes a decorative door panel, which is attached to the front of the main body 16 and is made of the same material and color as the doors of other system kitchen equipment.

A decorative plate female screw 20 is inserted into the door decorative plate 19 to form a recess 21 for engaging the L-shaped metal fitting 17.

Further, the decorative plate 19 and the L-shaped metal fitting 17 are engaged with a screw 22, and a prepared hole boss 24 is formed in the concave groove 11 of the μ cap 12, and is engaged with a screw 18.

Furthermore, since the L-shaped metal fittings 17 are visually exposed on the upper and lower surfaces of the door, a sense of unity with the door cap 12 can be created by fixing the cover metal fittings 23 with double-sided tape, adhesive, or the like.

Further, the lower door cap 26 having the U groove 26 constitutes a handle 27 and a control part 28, and a single-shaped metal fitting 29.
The door decorative board 19 is fixed through the door panel to create a sense of unity and harmony.

The function of the door decorative panel mounting structure configured as described above will be explained below.

When a refrigerator employing a water-world decorative board mounting structure is installed in a system kitchen, a coordinated sense of unity can be obtained because the surface material and color tone of the door decorative board 19 are the same in appearance.

Moreover, the door decorative board 19 is provided with a recess 21.
It also eliminates the gap between the door panel 13 and the door panel 13 to improve the appearance from the side.

The heat insulating performance of the shell is ensured by the heat insulating material 16 filled in the body 16 of the shell. Moreover, the L-shaped metal fitting 17
Since the decorative door panel 19 is locked to the single-shaped metal fitting 29, the engineering-shaped metal fitting 29 is engaged when inserted into the U groove 26.
The screw 18 is used to tighten the metal fitting 17 from the top or bottom of the layer. Further, a heat insulating material 16 is filled between the prepared hole bonu 24 and the inner plate 14. Therefore, there is no need to penetrate and tighten screws from the inside of the refrigerator through the heat insulating material 16, which varies in thickness, and it is possible to eliminate heat generated by heat conductors and sweat on the surface of the decorative board.

Furthermore, the decorative panel is temporarily fixed to the door body using L-shaped metal fittings and engineered metal fittings without driving screws from inside the refrigerator. In addition, the concave groove and U-groove allow for positioning in the left and right directions, making it possible to perform installation work easily and quickly without the complicated and long time required as in conventional methods. .

Therefore, an inexpensive decorative door panel structure can be achieved.

Effects of the Invention As described above, the present invention has a structure in which L-shaped metal fittings and single-shaped metal fittings are installed on the upper and lower door caps, and screws are driven from the top and bottom of the door body when attaching the door decorative panel to the door body. , there is no condensation on the door decorative panel surface, and the structure is not screwed in from the inside of the refrigerator, where insulation thickness often fluctuates during the door decorative panel installation process.
It is possible to provide a door decorative board structure in which the tips of screws do not come out on the surface of the door decorative board.

Furthermore, since the L-shaped metal fittings and the engineering-shaped metal fittings engage with the concave grooves and U-grooves of the door cap, it is possible to further improve the setting workability in left-right, up-down, and front-back directions.
