[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotation mechanism of an operation lid having a cover on an operation section which can be operated from the outside of a refrigerator.

[0002]

2. Description of the Related Art A rotating mechanism of an operation lid will be described using a refrigerator.

The refrigerator body 1 shown in FIG. 8 having two upper and lower doors is provided with an operation lid 4 below an upper door 2 which is one of the two doors.

FIGS. 4 and 5 show a conventional rotation mechanism of an operation cover.

As shown in FIG. 4, the conventional rotating mechanism of the operation cover 4 has an operation cover 4 having a side wall 9 provided with a rotation shaft 8 on both the left and right sides, and a front surface and a bottom surface communicating with each other so that each size can be operated. An operation unit cover 5 provided with an operation unit hole 13 having the same size as the lid 4 so as to be aligned when the operation cover 4 is rotated up and down, and a rotation shaft 8 provided in the operation cover 4
A board holder 6 having bearing ribs 11 provided on both left and right sides with a shaft hole 10 to be fitted with the circuit board, a circuit board 7 provided with a control circuit for controlling the temperature in the refrigerator, operation buttons and the like are provided. Operating unit (not shown).

The rotation shaft 8 provided on the side wall 9 of the operation lid 4 is fitted into the shaft hole 10 on the bearing lip 11 provided on the substrate holder 6 via the operation section cover 5. Thereby, the operation cover 4 and the operation section cover 5 are flush with each other, and the operation cover 4 rotates up and down around the rotation shaft 8 as shown in FIG.

The operation unit is provided on the front surface of the substrate holder so that the operation cover 4 can be operated from the front when the operation cover 4 is rotated downward, and the circuit board 7 is screwed on the rear surface of the substrate holder so as to be connected to internal components by a cord or the like. Etc. are fixed.

[0008]

However, in the conventional rotating mechanism of the operation lid having the operation unit on the door of the refrigerator, there is an error that the operation lid is pulled like the operation lid shown by the broken line in FIG. In use, if the operation lid is pulled strongly toward you, a force is applied to the rotating shafts on the left and right side walls of the operation lid,
As shown in FIG. 7, the rotating shaft is broken.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a rotation mechanism of an operation lid that does not exert a force on a rotation shaft provided on the operation lid even if the operation lid is pulled toward the user. Aim.

[0010]

The problems as described above SUMMARY OF THE INVENTION To resolve the, and manipulate the lid that Yusuke <br/> sidewalls provided with the rotary shaft on the left and right sides, the same size as the operation cover of operating portion and the operation portion cover the hole front and bottom are provided respectively so as to communicate the a substrate holder having a bearing ribs are provided rotary shaft and mating shaft hole which is provided on the operation cover
Become pressurized et al, a rotating mechanism of the operation lid operating cover around a rotational axis fitted to the shaft hole is rotated, the inner wall surface of the operation cover to the side walls provided on both left and right sides of the operation cover those An abutting portion is provided for contact.

[0011]

When the operation lid is pulled, the contact portion provided on the side wall comes into contact with the inner wall surface of the operation portion cover before a force is applied to the rotation shaft, so that the rotation shaft is broken without direct force being applied. Never.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the operation lid rotating mechanism of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing an embodiment of the operation cover rotating mechanism of the present invention.

The same parts as those of the prior art are denoted by the same reference numerals.

The rotating mechanism of the operation lid according to the present invention comprises an operation lid 14 provided with a side wall 12 having a rotation shaft 15 on both left and right sides.
And the front and the bottom communicate and the size of each is
An operation portion hole 13 having the same size as that of the operation portion 4 is provided so as to be aligned when the operation lid 14 is rotated up and down, and a shaft hole for fitting the rotation shaft 15 of the side wall 12 on both left and right sides. A substrate holder 18 provided with a bearing rib 11 provided with a circuit board 10, a circuit board 7 provided with a control circuit for controlling the temperature in the refrigerator, etc., and operation buttons for adjusting the temperature in the refrigerator are provided. Operation unit (not shown)
And is composed of

A contact portion 16 for contacting the inner wall surface 17 of the operation cover 5 when the operation cover 14 is pulled forward is provided on the side wall 12 of the operation cover 14. It is provided between.

The rotating shaft 15 provided on the side wall 12 of the operation cover 14 is connected to the operation hole 13 of the operation cover 5.
The operation lid 14 is aligned with the operation hole 13 of the operation unit cover 5 by being fitted into the shaft holes 10 on the bearing ribs provided on the left and right sides of the substrate holder 18 via the through hole. .

The operation section is mounted on the front surface of the board holder 18 so that the operation can be performed when the operation cover 14 is opened. The circuit board 7 is connected to internal components in the refrigerator by lead wires or the like, so that the operation section can be operated. It is screwed to.

The rotating mechanism of the operation lid assembled as described above rotates up and down around the rotating shaft 15 fitted in the shaft hole 10 on the bearing rib 11 of the substrate holder 18.

As shown by the broken line in FIG. 2, when the operation cover 14 is pulled toward the user due to misuse by the user, a force is applied to the rotating shaft 8 provided in the conventional operation cover 4. In contrast, as shown in FIG. 3, before a force is applied to the rotation shaft 15, the contact portion 16 provided between the operation cover 14 and the side wall 12 contacts the inner wall surface 17 of the operation portion cover 5, Since a force is applied to the contact portion 16, no direct force is applied to the rotating shaft 15 and the rotating shaft 15 is not broken.

In the present invention, the contact portion 16 is provided so as to connect the operation cover 14 and the side wall 12, but the contact portion is brought into contact with the inner wall surface 17 of the operation cover. 16
May be provided on the front outside of the side wall 9 as in the conventional example.

[0022]

According to the present invention, the rotating mechanism of the operation lid is configured such that the contact portions provided on the left and right side walls of the operation lid are attached to the inner wall surface of the operation portion cover when the operation lid is pulled forward. Because it is provided to abut, even if the operation lid is pulled forward due to misuse, force is applied to the corresponding contact,
Since no direct force is applied to the rotating shaft, it does not break.
