Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator provided with a freshness maintaining device for indirectly cooling a vegetable container arranged in a vegetable room from the surroundings so that vegetables and fruits can be stored for a long time.

[0002]

2. Description of the Related Art In recent years, refrigerators having a vegetable compartment that can be opened and closed by a drawer-type door have increased the concentration of ethylene gas released by the respiration of vegetables and fruits during the storage period of vegetables and fruits (hereinafter referred to as fruits and vegetables). In order to prevent the fruits and vegetables from spoiling, freshness maintaining devices that reduce the concentration of ethylene gas and maintain the freshness of the fruits and vegetables have been considered.

A conventional freshness maintaining device is disclosed in
Japanese Unexamined Patent Publication No. 238934/1990.

Hereinafter, a refrigerator provided with the above-mentioned conventional freshness maintaining device will be described with reference to the drawings.

FIG. 14 is a longitudinal sectional view of a conventional refrigerator.
FIG. 15 is an exploded perspective view of the vegetable container. In FIG. 14 , 2 is a vegetable room, 3 is a drawer door, and has a frame 4 formed in a substantially U-shape between left and right frames and a rear frame.
Reference numeral 5 denotes a vegetable container having an upper surface opening 6, and support flanges 7 are integrally formed on upper portions on both right and left sides, and are detachably mounted inside the frame 4 . The drawer door 3 is attached to the front opening of the vegetable compartment 2 via the frame 4 so as to be openable and closable. Reference numeral 8 denotes a storage recess, which is formed integrally with the vegetable container 5 in the space inside the container. Reference numeral 9 denotes a filter containing a catalyst for adsorbing and oxidatively decomposing ethylene gas and odor components. Reference numeral 10 denotes a filter cover having a ventilation hole 11, which is fitted and held in the housing recess 8 so as to prevent the filter 9 from dropping off, and forms a freshness maintaining device 12.

The freshness maintaining device 12 configured as described above
In the vegetable container 5, ethylene gas and odor components released by fruits and vegetables in the vegetable container 5 flow through the storage recess 8 through the vent hole 11 of the filter cover 10, touch the filter 9, adsorb and decompose on the catalyst in the filter, and It reduces the concentration of gas and maintains the freshness of fruits and vegetables.

[0007]

However, in the above-mentioned conventional construction, when the concentration of ethylene gas released from the fruits and vegetables in the vegetable container 5 becomes high, the ethylene gas is adsorbed by the catalyst built in the filter 9. In order to maintain the freshness of the fruits and vegetables by lowering the concentration, the concentration of eslen gas released from the fruits and vegetables is low in the low temperature zone in the vegetable container 5, and the selenium gas that does not promote the decay of the fruits and vegetables cannot exhibit the adsorption effect. was there.

In order to prevent the filter 9 from falling off,
After being placed in the storage recess 8 of the vegetable container 5, it is covered with a filter cover 10 having a ventilation hole 11 and fitted and held in the storage recess 8.
The filter 9 is inconvenient for the user to remove and replace, and has a drawback that the filter 9 cannot be held if the filter 9 is damaged or lost at the time of replacement.

The filter 9 having a built-in catalyst has a filter cover 1 having a vent hole 11 on the front surface for preventing falling off.
Since the filter 9 is fitted and held at 0, the ethylene gas cannot be adsorbed because the ethylene gas cannot touch the catalyst built in the filter 9 when the ventilation hole 11 is closed with fruits and vegetables, bags or the like. There was a disability that could not be effective.

[0010] Another object of the present invention is to provide a freshness-maintaining effect that can keep fruit and vegetables fresh.

[0011]

Means for Solving the Problems The present invention for achieving this object, and vegetable container having an open top, the vegetable container
Removable from the storage section formed on the upper part on the inner side of the
A freshness-proof antibacterial cassette to be attached;
Is open on the inner side and the upper side of the vegetable container,
Holding plates protruding from both ends of the opening are formed integrally,
The fresh antibacterial cassette is inserted through the upper opening of the storage section.
Inside of the vegetable container when inserted and installed in the storage section
Have a plurality of ventilation holes on both sides,
The supporting part is formed integrally, and the volatile antibacterial component
Fragrance with antiseptic properties in antibacterial material
It has a built-in antimicrobial freshness .

Thus, the antibacterial antimicrobial cassette can be easily attached and detached up and down with one touch.

[0013] Further, the ventilation hole of the fresh antibacterial cassette is provided on the back side of the storage portion of the vegetable container, and a certain gap is provided between the ventilation hole and the back wall of the storage portion. Also, a continuous rib is formed on the back wall and lower wall of the storage section from the upper opening end face to the lower wall front end face, and a ventilation path is provided .

As a result, the antibacterial and antibacterial effect can be further enhanced.

[0015]

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a vegetable container having an open upper surface.
Container and a storage portion formed at the upper portion on the inner side of the vegetable container
A fresh antibacterial cassette that can be attached to and detached from the top
The storage unit has an opening on the inner side and above the vegetable container.
The holding plate protruding from both ends of the opening on the inner surface side
Formed in the body, the fresh antibacterial cassette is
When installed by inserting it into the storage section from the upper opening,
The vegetable container has a plurality of ventilation holes on the inside surface,
The support portion held by the holding plate is integrally formed.
Antibacterial material with volatile antibacterial ingredients
It has a built-in antibacterial freshness into which a scented substance is incorporated .

[0016] The volatile antibacterial antibacterial substance, which effectively controls the generation of ethylene gas released from the fruits and vegetables, is contained in the antibacterial antibacterial cassette. You can do it.

Also, a vegetable container and an inner surface of the vegetable container
The storage section formed at the top of the
For example, the storage portion is opened on the inner side and the upper side of the vegetable container.
The antimicrobial freshness cassette contains volatile antimicrobial freshness.
Having a ventilation hole on the side facing the back wall of the storage section,
A certain gap is secured between the ventilation hole and the back wall of the storage section
Is what is being done.

Thus, even when fruits and vegetables, bags and the like are placed on the front surface of the fresh antibacterial cassette on the inner side of the vegetable container, the ventilation hole of the fresh antibacterial cassette has a certain gap on the back wall side of the storage portion, so the hole is closed. Without releasing the antibacterial preservative component.

Further, a plurality of convex ribs continuous from the upper opening end face to the lower wall end face are formed on the inner wall and the lower wall of the storage portion of the vegetable container, and an air passage is provided.

Thus, when the fresh antibacterial cassette is inserted, the fresh antibacterial cassette is held down by the plurality of ribs to form a cylindrical ventilation path. Even if it is placed, since the ventilation hole faces the ventilation path, the antibacterial freshening component can be smoothly diffused through the ventilation path to the whole vegetable container, and the freshening effect can be increased.
