Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a deodorizing device for a refrigerator, and particularly to a deodorizing device suitable for alkaline and acidic odors such as fish, meat, vegetables, etc.

[Background of the invention]

The conventional deodorizing device for this type of cooling device was developed in 1988-12.
As shown in 73ss, etc., a deodorizer was removably installed in a cold air passage formed in a partition wall separating a freezer compartment and a refrigerator compartment. However, this product did not provide a honeycomb-like cold air passage in the deodorizer itself, nor did it take into consideration the deodorizer that removes both acidic and alkaline odors.

[Purpose of the invention]

The present invention has been made in view of this point, and is designed to remove odors from refrigerators and freezers that have various characteristics.

[Summary of the invention]

In order to achieve this purpose, activated carbon structured in a honeycomb shape and zeolite (aluminum A deodorizing agent containing ferrous sulfate (silicate) impregnated was designed to achieve the above object.

[Embodiments of the invention]

The details of the present invention will be explained below with reference to an embodiment shown in the drawings.
2 is the refrigerator main body, 2 is an inner box forming the inside of this main body 1,
This inner box 2 has a freezer compartment 3 and a refrigerator compartment 4 formed therein. 5 is a partition wall that divides the freezer compartment 3 and the refrigerator compartment 4; 6 is a cooler installed at the back of the freezer compartment 3; 7 is a cooler that supplies cold air cooled by the cooler 6 to the freezer compartment 3 and the refrigerator compartment 4. Forced circulation blower, 811 indicates the cold air return passage of the freezer compartment 3, 9 indicates the cold air return passage of the refrigerator compartment 4
Shows the cold air return passage. 10 is removably provided;
This deodorizing device 10 is as shown in the figure (
, activated carbon ASB and case C.

However, activated carbon A is ordinary activated carbon made from ordinary coconut husks, etc., and deodorizer B is zeolite (aluminum silicate).
This is a deodorizing agent with ferrous sulfate attached to it. Furthermore, the activated carbon A and the deodorizing agent B are formed into a honeycomb shape by extrusion molding or the like so as to form a cold air passage 11 inside. In the present invention, this honeycomb-shaped activated carbon and deodorizing material are installed in the cold air return passage 9 of the refrigerator compartment.

Incidentally, if the activated carbon A and the deodorizing agent B are integrated by impregnating the activated carbon with ferrous sulfate, the space factor will be improved.

The deodorizing effect in the refrigerator thus constructed is performed as follows.

That is, relatively acidic odors emitted from fish, meat, etc. are removed by the deodorizer B when returning to the cooler 6 through the cold air return passage 9 of the refrigerator compartment.
It is chemically adsorbed to the ferrous sulfate inside.

Furthermore, alkaline odors emitted from vegetables and the like are adsorbed by the activated carbon A when returning to the cooler via the cold air return passage 9 of the refrigerator compartment.

〔Effect of the invention〕

As explained above, the present invention consists of activated carbon and zeolite (aluminosilicate) configured in a honeycomb shape to form a cold air passage of a cold air suction passage formed in a partition wall etc. that partitions a freezer compartment and a refrigerator compartment. Since it is equipped with a deodorizing agent impregnated with ferrous sulfate, it can adsorb two or more types of odors with different characteristics more efficiently than circulating cold air.

In addition, since the honeycomb-shaped activated carbon and deodorizer, which are each made of different materials and are formed independently, are installed in a single case and installed in the cold air passage, they can be easily attached and detached. .

Claims (1)

[Claims] 1. A deodorizing agent made of activated carbon and ferrous sulfate in zeolite (aluminum silicate) are added to the cold air suction passage formed in the partition wall etc. that separates the freezer compartment and the refrigerator compartment. What is claimed is: 1. A deodorizing device for a refrigerator, characterized in that a deodorizing agent having a deodorizing agent attached thereto is provided, and both of the deodorizing agents are formed into a honeycomb shape. 2. The deodorizing device for a refrigerator according to claim 1, wherein both of the deodorizing agents are housed in one case, and the case is provided in a cold air suction passage.
