Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a refrigerator in which the humidity or temperature in a rotating container installed in a refrigerator or a vegetable room can be changed depending on the vegetables stored in the container. It concerns containers.

[Background of the invention]

The present invention is based on a well-known technology, as described in Japanese Utility Model Application Publication No. 53-28971, in which a shutter is attached to a container installed in a refrigerator and cold air is introduced by opening and closing the shutter. .

However, when using a plurality of stacked containers, there are restrictions regarding the position of the shutter, etc.

[Purpose of the invention]

An object of the present invention is to enable the shutters to be easily opened and closed even when containers are stacked in multiple tiers.

[Summary of the invention]

In a refrigerator in which two rotating containers having approximately the same upper surface shape are installed in two stacks, a plurality of slit-shaped openings are provided in the lid that covers the upper surface of the lower container of the rotating containers, and the openings are approximately the same as the openings. When attaching a shutter having the same number of openings to the opening surface of the lid, a guide foot provided on the shutter side is engaged in a guide groove provided on the lid so that the shutter can slide within a predetermined range. A container for a refrigerator, characterized in that the shutter is mounted to be switchable in three stages: closed, half-open, and fully open, and the shutter is positioned close to the refrigerator door.

[Embodiments of the invention]

Hereinafter, an embodiment of the present invention will be described in detail with reference to FIGS. 1 to 5. 1 is an inner box of a refrigerator forming a refrigerator compartment 2, and 3 is a front surface of the refrigerator compartment 2. This is a door that closes off an opening. 4,5
This vegetable container is rotatably mounted in the refrigerator compartment 2 with a rotating shaft 6, and is composed of an upper container 4 and a lower container 5. 7 and 8 are lids that cover the upper surface of the container, 7 is for the upper container, and 8 is for the lower container.
The lids 7, 8 have sealing packings 9, 10 as shown in the figure. 7a, 7b, 8a, 8b
is the lid frame, which forms the outer shell of the shutter. 1
1 is a lid 7, 8 installed on the upper surface of the container 4, 5.
This is an opening provided in the This opening 11 is slit-shaped and is installed close to the door 3 so that it can be easily operated even when the upper container 4 is pulled out, especially in the case of the lower lid. 12 is an aperture 12 that has approximately the same shape as the previous aperture and has the same number of slits.
It is a shutter with b. This shutter 12
is attached to the container by engaging the guide foot 12a on the shutter side into the hole 13 provided on the lid side so as to be able to slide within a predetermined range on the opening surface on the lid side. 14 is a recess formed in the hole 13, and when the protrusion 12a of the shutter 12 is in the recess A, the opening of the shutter 12 of the lid 7 coincides with the opening of the shutter 12, as shown for example in the upper container 4, and the cold air in the refrigerator compartment is drawn into the container. It is a structure that leads you inward. At this time, the distance between the shutter 12 and the lid frame 7a is L. When the projection 12a of the shutter 12 is in the recess C, the opening of the lid 7 and the opening of the shutter 12 are misaligned, as shown in the lower container 5, so that cold air does not enter the container from the opening. At this time, the distance between the shutter 12 and the lid frame 7a is l (same state as in FIG. 2). Protrusion 12a
When the container is in the recess B, half of the opening on the lid side is covered by a shutter 12, and the humidity and temperature are changed depending on the vegetables stored in the containers 4 and 5.

Incidentally, FIG. 5 shows a diagram with the shutter 12 removed from FIG. 2.

Generally, when a container has a lid of this type, there is a difference between the temperature inside the refrigerator and the temperature inside the container, and dew forms on the container side. This dew accelerates damage to vegetables, so countermeasures against this dew are very important, but by using a switchable type as in the present application, it is possible to minimize the amount of dew inside the container. It is something.

〔Effect of the invention〕

As explained above, the present invention not only allows the humidity and temperature inside the container to be arbitrarily selected depending on the type of vegetables to be stored with a simple shutter operation, but also allows rotating containers to be installed in two layers. In a refrigerator with a built-in design, the shutter is located close to the door so that it can be easily operated even if the upper container is pulled toward you. It can be operated.

Claims (1)

[Claims] 1. In a refrigerator in which rotating containers having approximately the same top surface shape are installed in two tiers, a plurality of slit-shaped openings are provided in the lid that covers the upper surface of the lower container of the rotating containers, and the openings are approximately the same as the openings. When installing a shutter having the same shape and the same number of openings on the opening surface of the lid, the guide foot provided on the shutter side is inserted into the guide groove provided on the lid side so that the shutter can slide within a predetermined range. The shutter is mounted so that it can be switched in three stages: closed, half-open, and fully open, and the shutter is located at a position where the overlapping relationship between the containers is released when the upper container is rotated, and where it can be easily operated.
