Description

Description: [Industrial field of application] The present invention relates to a door body having an operation panel on the front surface of, for example, a refrigerator.

 The case of a refrigerator door will be described below.

[Prior Art] FIGS. 11 and 12 show an example of a conventional refrigerator shown in Japanese Utility Model Application No. 62-145566. FIG. 11 is a perspective view of the refrigerator main body, and FIG. FIG. 11 is an enlarged sectional view of a main part of FIG.

In the figure, (1) is a refrigerator main body, (2) and (3) are freezer compartment doors and refrigerator compartment doors which are opening and closing doors mounted so as to cover the front opening of the refrigerator main body in an airtight manner, and (4) is A door outer plate (5) of the freezer compartment door is an electric component cover fixed to the back surface of the opening opening in the door outer plate and forming a space (6).

(8) is an operation part main body arranged in the space part (6), and the temperature inside the refrigerator main body (1) can be adjusted by operating an external temperature setting knob (7). It also has the function.

(9) is a mounting plate forming the operation section body (8), and (11) is a print fixed to the boss (12) integrally provided on the back surface of the mounting plate (9) with screws (13). On the board, a knob body (14) for temperature control, which can selectively and arbitrarily set the temperature inside the refrigerator by operating the knob (7), is fixed by soldering or the like.

The boss (12) of the mounting plate (9) is provided with a predetermined gap so that the knob body (14) arranged on the printed circuit board (11) and electronic parts do not come into contact with the mounting plate (9). Is formed. Further, in the positional relationship between the electrical product cover (5) and the mounting plate (9), if the electrical product cover (5) is deepened, a predetermined thickness of the heat insulating wall of the freezer compartment door (2) can be secured. Disappear.

For this reason, in order to prevent the occurrence of dew on the freezer compartment door (2), the electrical equipment cover (5) is made shallow so that the mounting plate (9) projects forward from the door outer plate (4). Is forming.
Note that (10a) is a decorative cover that covers the temperature setting knob (7) in an openable and closable manner, and (15) is a foamed heat insulating material such as polyurethane foam that is foamed in situ.

[Problems to be Solved by the Invention] The operation section body (8) mounted on the conventional freezer compartment door (2)
Since the above is configured, the operation section body (8)
Due to the large depth dimension from to the printed circuit board (11),
It is necessary to make the operation part main body (8) project forward from the door outer plate (4) or to make the depth of the concave electric component cover (5) deep.

In the former, there are problems in that the operation portion is projected to the door surface side to impair the aesthetic appearance and the depth dimension of the refrigerator main body is increased, compared with the flat face design which is currently popular. Further, in the latter case, there is a problem that the thickness of the heat insulating wall of the door becomes thin and heat is leaked from the freezing compartment to cause dew condensation on the printed circuit board, the electrical component cover and the like.

The present invention has been made to solve the above problems, and an object thereof is to obtain a door body in which the depth of the operation portion main body is small, and the operation portion main body and the decorative cover are less likely to project from the surface of the door outer plate.
