Abstract

PURPOSE:To widen the freedom to select a design of the door and to prevent heat conduction by the interruption of a door frame reinforcing plate and a door rear plate reinforcing plate by bending the end surface of the vertical side of a door front plate. CONSTITUTION:The appearance of a door 15 is formed by a door cover 18 for covering a door front plate 16 of a highly vivid painted steel plate in which a vertical side is bent so that the end surface is opened and an end surface 17 of a horizontal plane part of a door front plate of a bending type door front plate 16. The end part of the vertical side of the bending type door front plate 16 is bent in C-type so as to be opened. Thus, a vertical C-shaped part 19 of the door front plate is formed. A door frame 20 is formed by extrusion molding of a resin such as vinyl chloride or the like. V-cuts are applied at four positions to form a four-side bent flame body. The C-shaped part 19 on the vertical side formed in the bending type door front plate 16 is inserted into a door groove 21. Further, in the door frame 20 and the door cover 18, a rib B23 of the door cover is fixed by a claw 24 provided in the door frame 20.

Description

[Detailed description of the invention] Industrial applications The present invention relates to doors of refrigerators and the like.

Conventional technology In recent years, in order to improve the appearance quality of refrigerators, high-definition P has been applied to the door front panel.
Doors using CM-painted steel plates have become mainstream, and their structure is such that when the high-definition coated steel plate is squeezed, the surface paint will crack, so the high-definition coated steel plate is used as a flat door plate. A satshu large door method is used in which the periphery is inserted into a door frame made of extruded material such as PVC, and a door reinforcing plate is inserted into the door frame to further ensure the strength of the door.

An example thereof will be explained below with reference to FIGS. 6 and 6. In the figure, reference numeral 1 indicates the refrigerator body, and a handle 6 is attached to the front door surface of the refrigerator body. The door includes a flat door front plate 4, a door frame 6 covering the outer periphery of the flat door front plate 4, a door back plate 7 facing the flat door front plate 4, the flat door front plate 4, It is composed of a door frame 6 and a foamed polyurethane heat insulating material 8 filled between a door back plate 7. 9 is a recess provided in the door frame 6 into which the flat door front plate 4 is inserted.

Further, 10 is a groove provided in the door frame 6 into which a gasket 11 is inserted. 12 is a door frame reinforcing plate inserted into the door frame 6. Further, 13 is a door back plate reinforcing plate installed on the flange portion 14 of the door frame 6.

In this configuration, the high-definition painted steel plate is used as the door surface material without being squeezed, thereby improving the appearance quality of the refrigerator. The strength of the door frame reinforcing plate and the door back plate reinforcing plate 13 are used to strengthen the strength against the moment load using the gap as a fulcrum.

Problems to be Solved by the Invention However, in order to use such a flat plate-like front plate 4 as a structure as a door 2, its peripheral edge must be inserted into the door frame 6. The choice of door design is limited, and the door frame reinforcing plate 12 and door back plate reinforcing plate 13, which are intended to strengthen the door, are in contact with the door frame 6, which is a drawback of the large door method. As a result, the temperature of warm air outside is conducted through the door frame 6, increasing power consumption.For the same reason, condensation tends to form on the door frame 6.

The present invention solves the above-mentioned conventional problems, and aims to expand the degree of freedom in selecting door designs and eliminate heat conduction by cutting the edges of the door frame reinforcing plate and the door back plate reinforcing plate. It is said that

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention bends the upper and lower end faces of the door face plate to open them, inserts covers on the left and right sides of the ends, and then closes the upper and lower sides of the door face plate. A door frame is inserted into the sides and the cover from above to form a door structure.

Function: With the above-described configuration, the present invention can form a door structure and expand the degree of freedom in selecting the door design, as well as improve the temperature conduction of warm air from the outside through the structure and the temperature conduction of the door from the inside. It is possible to prevent sweating due to cooling of the door cover by the structure.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIGS. 1, 2, 3, and 4. In addition, the same reference numerals are attached to the same configuration as the conventional one, detailed explanation thereof will be omitted, and only the different parts will be described.

In the figure, 16 is a door, which includes a door top plate 16 (hereinafter referred to as folded large door top plate) made of high-definition painted steel plate whose upper and lower sides are bent so that the end faces are open, and A door cover 18 for covering the left and right flat end surfaces 17 of the bent large door surface 16
In other words, it constitutes the appearance of the door 15. The upper and lower ends of the folded large door face plate 16 are bent into a C-shape so as to be open, thereby forming upper and lower C-shaped parts 19 of the door face plate (
(hereinafter referred to as C-shaped part). Reference numeral 20 is a door frame made by extrusion molding of resin such as PVC, which is cut in 4 places and bent on all sides to form a frame body, and the folded large door face is inserted into the door groove 21 provided in the door frame 2o. C-shaped portions 19 formed on the upper and lower sides of the plate 16 are inserted.

Also, the left and right sides are lip A of the door cover provided on the door cover 18.
22 is inserted into a door groove 21 provided in the door frame 20. Further, the door frame 20 and the door cover 18 are connected to the door cover 18.
A lip B23 of the door cover provided on the door frame 2o is fixed by a claw 24 provided on the door frame 2o.

In such a configuration, in the configuration of the foldable large door top plate 16, even if the door top plate material has poor drawing properties, if it can be folded, it can be used as the door top plate material. In addition, since the upper and lower sides of the folded large door face plate 16 are bent and processed into a C-shaped portion 19, there is no need to strengthen the strength against the moment load using the hinge 3 as a fulcrum due to the door 15's own weight. becomes.

With this structure of the door 16, even if it is made of high-definition coated steel plate that has poor creasing properties, it can be used as the door surface material if it can be bent. The degree is expanded. Also, the upper and lower sides of the bent large door front plate 16 and the C-shaped part 1
9, it can also serve as strength reinforcement against the moment load between the hinges 3 due to the door's own weight, so the door frame reinforcing plate 12 and the door back plate reinforcing plate 13 are unnecessary, so the door structure As a result, it is possible to prevent heat conduction through the external winding, thereby reducing power consumption and preventing dew condensation on the surface of the door cover 18.

Effects of the Invention As is clear from the above explanation, even materials with poor drawing properties can be applied to the door face plate having the door structure of the present invention as long as they can be bent and bent, and the door design can be improved. It has become possible to expand the degree of freedom of choice.

In addition, since a reinforcing structure for the door frame is not required, it is possible to strengthen the door frame and prevent heat conduction to the outside and inside through the structure, reducing power consumption and preventing sweating of the door cover, etc. It has excellent effects.
