Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door of a refrigerator or the like in which a door is provided with a substrate for controlling temperature control of a storage chamber.

2. Description of the Related Art A conventional example will be described with reference to FIG.
Reference numeral 2 is a door outer plate, and 3 is a door inner plate. Reference numeral 4 denotes a heat insulating material such as urethane foam filled between the door frame 1, the door outer plate 2 and the door inner plate 3. Reference numeral 5 denotes a substrate for operating temperature control of the storage room, etc., which is fixed to a decorative plate 6 such as a synthetic resin installed on the door outer plate 2. A magnet 7 is fixed to the decorative plate 6 by adhesion or the like. Reference numeral 8 denotes a lid body that is rotatably disposed on the decorative plate 6 so that the operating portion of the substrate 5 can be closed / opened so as to be rotatable around the projecting boss 9. There is.

Problems to be Solved by the Invention However, according to the above-described configuration, the magnet is exposed on the surface, so that the appearance design is restricted and the appearance is deteriorated.

In addition, in order to improve operability such as temperature control, a mechanism for holding the lid body in a fully opened state has been separately required.

In addition, functional problems such as falling off and damage of magnets and rusting of metal plates have also arisen as practical problems. Therefore, the material cost and labor cost are high due to the increase in the number of constituent parts and the complexity of the assembling process, resulting in high cost.

The present invention has been made in view of the above drawbacks, and an object thereof is to provide a door for a refrigerator or the like that reduces material costs and assembly labor costs and solves quality problems.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention arranges a substrate for operating temperature control of a storage chamber on a decorative plate made of synthetic resin or the like, and freely closes or opens the operating portion. In order to hold the lid locked to the closed state or the open state in any one of the closed states, a claw is provided on the corresponding portion of the decorative plate made of synthetic resin or the like to form a door.

Effect The present invention has the above-described configuration, and the claw provided on the decorative plate made of synthetic resin or the like closes the portion for operating the temperature control of the storage chamber.
The lid body to be opened can be held in either the closed state or the open state.

Example Hereinafter, an example of the present invention will be described with reference to FIGS. 1 to 4. The same parts as those of the related art are designated by the same reference numerals and the description thereof will be omitted. Reference numeral 11 is a decorative plate on which the substrate 5 for operating the temperature control of the storage room is fixed, and 13 is a lid provided to close and open the operating portion of the decorative plate 11, which can be rotated on the decorative plate 11. Protruding bosses 14 are provided on the left and right as axes. Further, 12 is a decorative plate 11 for holding the lid 13 in either a closed state or an open state.
It is a nail provided on the.

Here, the retention of the closed state of the lid body 13 will be described with reference to FIG. 1. The claw 12 uses the elasticity of the synthetic resin above the protruding boss 14 serving as the rotation axis of the lid body 13 at its tip end. The lower end portion of the lid body 13 is in close contact with the decorative plate 11 because it is pressed against the decorative plate 11. That is, the operating portion is held in a closed state. Next, the holding of the lid 13 in the open state will be described with reference to FIG. Nail 12
Has a surface on one side formed in substantially the same shape as the upper outer surface of the lid body 13.When the lid body 13 is rotated to open the operating portion, the lid body 13 is brought into contact with the surface pressure by the claw 12. The condition of being held by This state is configured so as to coincide with the case where the lid body 13 is fully opened.

Due to the above-mentioned configuration, a mechanism for holding the lid body that can be closed / opened in the operation part for temperature control of the storage chamber in either the closed state or the open state. However, without restricting the degree of freedom in design, stable in quality, and having a simple structure, a material cost, an assembly labor cost, and a low cost can be realized.

EFFECTS OF THE INVENTION As described above, according to the present invention, a substrate for operating temperature control of a storage room, a decorative plate made of synthetic resin or the like arranged to fix and install the substrate, and the operation portion can be closed and opened freely. Since the lid provided on the can be held in either one of the closed state and the open state by the only nail of the decorative plate, this mechanism can be designed without losing the appearance. It eliminates the constraint of the degree of design freedom of the thing. Further, since the holding structure is simple and reliable, the quality can be stabilized and the components can be simplified, and the material cost, the assembly labor cost, and the cost can be realized.
