Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a decorative plate mounting structure for a door of a freezer or a refrigerator which is housed and installed in a system kitchen or a unit type kitchen.

[0002]

2. Description of the Related Art Conventionally, such a technique is described in West German Patent, DE
As shown in No. 3425991C1, the door of a freezer or a refrigerator is filled with a heat insulating material in order to unify the color tone, material, decoration, etc. with the door of a system kitchen or other unit type closet. It was designed to fit the decorative plate from the outside to the main body.

Hereinafter, the conventional refrigerator door as described above will be described with reference to the drawings.

FIG. 3 is a perspective view of a conventional refrigerator for a system kitchen provided with a refrigerator door, FIG. 4 is a vertical sectional view of the refrigerator, and FIG. 5 is a vertical sectional view of the refrigerator door. 1 is a refrigerator main body, 2 is a heat insulation door, 3 is a decorative plate that matches the door of the system kitchen equipment, 4 is a main body door, an outer shell 5 and an inner plate 6
A heat insulating material 7 is filled in between.

A through hole 8 is provided in the main body door 4, and a screw 9
The decorative plate 3 is locked by. The handle 10 of the decorative plate 3 is fixed by screws 11 from the back side, and the screw head 12 projects from the back side of the decorative plate 3. A hole 13 is provided in the outer shell 5 of this portion, and a cushioning material 14 is incorporated in the heat insulating material 7 side.

The function of the door of the refrigerator constructed as above will be described below.

It is necessary to match the distance from the floor surface to the lower end of the decorative plate, that is, the rise height, between the door of a system kitchen or a unit type kitchen shelf and the door of a refrigerator.

Therefore, in appearance, the same material and color tone as those of other system kitchen appliances are used for matching with the decorative plate 3, and the lower end is backed up at a position where the rise height is almost matched with that of the decorative plate 3. I was physically. Further, fixing of the decorative plate 3 is performed from the inside of the refrigerator by passing the screw 9 through the through hole 8 provided in the main body door 4, and the inner plate 6 is arranged to cover the screw 9.

Moreover, the fixing screw 11 of the handle 10 of the decorative plate 3 is provided with the hole 13 of the outer shell 5 through which the screw head 12 is inserted from the back side of the decorative plate 3 and the buffer head 14 is embedded.

In FIG. 5, the thin door decorative plate 17 has the sash structure 15 fixed to the main body door 4 with screws 16 from the front, and the thin door decorative plate 17 is inserted and mounted in the sash structure 15.

[0011]

However, in the above-mentioned structure, the rise height varies depending on each manufacturer, and in order to back up the body door from the back, it is necessary to make a body door suitable for each manufacturer. there were.

Further, since the decorative plate and the outer shell are in close contact with each other, the outer shell swells due to the heat insulating material, causing a gap between the decorative plate and the outer peripheral portion, which is a factor of deteriorating the appearance quality.

Moreover, when the rise height is low, the main body door blocks the air convection port for heat radiation provided in the lower part of the front surface of the refrigerator to hinder the heat radiation effect, and the structure becomes complicated, resulting in an increase in cost. was there.

The present invention has been made in view of the above problems, and by simply changing the height of the decorative plate, it is possible to freely follow the rise height of the system kitchen of each manufacturer and to dissipate heat from the lower part of the front of the refrigerator. It is intended to provide a refrigerator door capable of ensuring the appearance quality without blocking the air convection port for the refrigerator.

[0015]

In order to solve the above-mentioned problems, a refrigerator door of the present invention comprises a refrigerator main body door, a thick-walled door decorative plate locked to the surface of the main body door, and the main body door. And a locking screw that locks the thick-walled decorative plate, and the upper end of the thick-walled decorative plate is substantially level with the upper end of the main body door,
By changing the height of the thick-walled decorative plate and changing the amount of protrusion of the thick-walled decorative plate from the lower end of the main body door, the distance from the refrigerator installation floor to the lower end of the thick-walled decorative plate can be increased. It was made adjustable.

Further, the main body door of the refrigerator, the sash decorative plate on the surface of the main body door, the thin-walled decorative plate sandwiched and inserted into the sash decorative plate, and the sash decorative plate and the main body door are locked. Locking screw, and the upper end of the sash decorative plate is made substantially flush with the upper end of the main body door, and the height of the sash decorative plate is changed so that the sash decorative plate extends downward from the lower end of the main body door. By changing the amount of protrusion of, the distance from the floor where the refrigerator is installed to the lower end of the sash decorative plate can be adjusted.

Further, a sash structure around the entire circumference of the door, a coated metal plate, a back plate of the back door, a main body door of the refrigerator composed of a gasket, a thick-walled decorative plate attached to the main body door, and the above-mentioned thickness. The meat door decorative plate has a handle provided with a locking screw, a space is provided between the sash structure, the painted metal plate, and the thick door decorative plate, and the locking screw head is housed in the space. I did.

[0018]

The refrigerator door of the present invention has the above-mentioned structure.
By changing the height of the thick-walled decorative plate and changing the amount of protrusion of the thick-walled decorative plate from the lower end of the main body door, the distance from the floor where the refrigerator is installed to the lower end of the thick-walled decorative plate can be adjusted. Therefore, it is possible to cope with the rise height of the system kitchen of each manufacturer, and further, it is not necessary to block the air convection port for heat radiation provided in the lower part of the front of the refrigerator.

Further, by changing the height of the sash decorative plate to change the protruding amount of the sash decorative plate from the lower end of the main body door downward, the distance from the floor where the refrigerator is installed to the lower end of the sash decorative plate can be adjusted. , It is possible to cope with the rise height of the system kitchen of each manufacturer, and it is not necessary to block the air convection port for heat radiation provided in the lower part of the front of the refrigerator.

Further, since the space portion is provided between the door decorative plate and the painted metal plate of the main body door via the sash structure, there is no occurrence of an outer peripheral gap due to swelling of the outer shell when the heat insulating material is foamed. The head of the system fixing screw can be stored and the appearance quality can be secured.
