Description

[Detailed Description of the Invention] The present invention relates to an improved structure of a door device for a refrigerator, a hot storage, etc., and in particular, the opening/closing angle of the door is set in multiple stages.

Conventionally, this type of door device for a refrigerator or the like has been provided with a stopper that limits the opening angle of the door in order to prevent the door from colliding with the main body and damaging the paint on the main body when the door is opened.

However, this opening angle is fixed at a predetermined constant angle, so that there will be no problem when taking out and taking out everyday items, but large items that are different from everyday items, and When putting in and taking out a shelf, etc., the opening angle is small and the door gets in the way, causing great difficulty.

Therefore, it may be possible to set the opening angle of the door so that it stops at a large angle suitable for taking in and taking out these large items, but when taking in and out small items on a daily basis, opening it wide will cause the closing action. The stopper is large and difficult to handle, and the impact applied to a portion of the stopper is also large, requiring the use of a member with high impact resistance, resulting in an increase in cost.

This proposal has been developed in view of the above-mentioned points, and will be described below with reference to the drawings, assuming that an embodiment of the storage is a refrigerator.

Reference numeral 1 denotes a refrigerator main body composed of an inner box 2, an outer box 3, a heat insulating material 4 filled between the two boxes 2 and 3, etc., and a storage chamber 5 formed by the inner box 2, etc. is cooled inside. The necessary devices such as a cooler 6 and a blower 7 for forced circulation are provided, and the front opening of the storage chamber 5 is closed with an arbitrary door 8 such as a transparent body with a frame so as to be openable and closable. There is.

The iron door 8 is rotatably supported at its upper and lower sides on upper and lower hinges 9 and 10 mounted on the main body 1 facing each other.

This lower hinge 10 has a shaft 1 which is pivotally fitted into the door 8.
The other end of the stopper 13, which has a long sliding hole 12 biased toward one end, is provided at a suitable location apart from the support pin 1.
It is supported by 4.

A sliding pin 15 is provided on the opposing bottom surface of the door 8 to project downward and is always slidably engaged with the sliding slot 12 of the stopper 13.

The sliding elongated hole 12 includes a second hole 12B extending toward the side closer to the lower hinge 10, and a second hole extending toward the free end side that is slightly spaced apart from the 17L12A in the parallel direction and further spaced from the lower hinge 10. 12B, etc., and the starting end of the 27th L12B is located slightly closer to the lower hinge 10 than the ending end of the first hole 12A, and the terminal end of the first hole 12A and the 27th L1
2B through the connecting hole 12C, and connect the first end (L12
A and the second hole 12B are connected to form a so-called lightning bolt-shaped sliding elongated hole 12.

The lower hinge 10 and the stopper 13 collide or come very close to each other when the door 8 is opened to its maximum extent, and a contact piece 16 prevents the door 8 from opening beyond the maximum allowable angle due to inertia.
, 17 are each formed by bending or mounting.

It is possible to achieve the desired purpose using only one of the contact pieces 16, 17.

18. 19 is a machine chamber 20 formed at the outer bottom of the main body 1.
a refrigerant compressor and a condenser disposed within the cooler 6;
Together with other components, it forms a refrigerant cycle.

Since the present invention has the above-mentioned configuration, during normal use, the sliding pin 15 provided on the door 8 slides on the 17th L 12 A, comes into contact with the end of the first hole 12A, and then touches the end of the door 8 beyond that. prevent the opening of

If you want to open the door 8 even wider when delivering large items or the storage shelf 21, etc., open the door 8 until the sliding pin 15 reaches the end of the 17th L12A, and then close the small door 8. 15 enters the connecting hole 12C and moves to the starting end of the 27th L12B.

After that, when the door 8 is opened again, the sliding pin 15 is moved to the first position.
By sliding the second hole 12B extending toward the free end side of the hole 12A, the door 8 can be opened at a larger angle than usual.

To close the door 8, perform the opposite operation.

Therefore, the opening angle of the door can be easily selected depending on the purpose of use, and the door can be used satisfactorily without unnecessary effort.

Further, since the door is not opened more widely than necessary during normal use, the impact applied to the hinge is small, and damage and deformation of the hinge and the main body can be reduced.

In addition, in this proposal, the example of the storage was explained as a refrigerator, but
The same applies to microwave ovens and other cooking devices, which are a type of storage in the broad sense of the word.

Further, although it is desirable for the design to provide the stopper on the lower hinge, the intended purpose can be achieved even if the stopper is provided on the upper hinge.
