Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to the structure of installing a deodorizing material (activated carbon made from coconut shell or the like) into a refrigerator.

BACKGROUND OF THE INVENTION J Refrigerators contain odors because they store a variety of foods. People with the 1-bug type keep activated charcoal in the corner of the refrigerator to get rid of the itchiness. However, since the above-mentioned activated carbon is usually packed in granular form in a container, it has not been possible to reach the point where the surface area of each individual granular activated carbon contributes entirely to the chicken's temperature. Also, even though it is a corner,
This method had the disadvantage that a part of the inside of the refrigerator was left open to install the activated carbon.

[Purpose of the invention]

In order to improve the defect described in 1-1, the present invention replaces the conventional granular activated carbon with a 2-cam-shaped activated carbon formed by extrusion or the like, and divides the installation location of the activated carbon into a freezing room and a cold IC room. It is installed in a suction passage formed in a heat insulating wall to improve the space factor and to obtain an efficient deodorizing effect.

[W1 hair of the invention] That is, the entrance part of the suction passage formed in the heat insulating wall and the honeycomb activated carbon (formed in a honeycomb shape with many holes) manufactured by extrusion molding etc. A mounting plate with a slit is installed so that the frontage is divided and the passage inside the activated carbon is parallel to the suction passage.

[Embodiments of the invention]

Hereinafter, details of the present invention will be explained using an embodiment shown in the drawings.
2 is a refrigerator main body, and 2 and 6 are freezer compartments and refrigerating compartments formed inside the refrigerator main body 1.

4 is an insulating wall that partitions the freezer compartment 2 and the refrigerator compartment 6; 5 is a cooler installed at the back of the freezer compartment 2; and 6 is a cooler that supplies cold air cooled by the cooler 5 to the freezer compartment 2 and the refrigerator compartment 6. A blower 7 for forced circulation is a fan guard installed in front of the cooling chamber 8 where the cooler 5 and the like mentioned above are installed. Reference numeral 9 indicates a passage for returning cold air in the freezer compartment 2 to the cooler 5; 10 indicates a suction passage for returning cold air in the refrigerator compartment 6 to the cooler 5; and an inlet portion 10a and L of this suction passage.
It has a law that allows 11 is activated carbon installed in this inlet part 10a, this activated carbon 11 is made of coconut shell etc. as a raw material -C
A large number of holes are extruded into a honeycomb shape. This activated carbon is in the population section 10a room 1''・]゛? Man? Person I
, + (It is installed so that it becomes L2. Father, this charcoal 11 is installed on the mounting plate 16 in which the slit 12 is formed.
The activated carbon 11, in particular the activated carbon 11, is attached to its receiving part 16;2. Therefore, all the powder produced by the weathering of the active 1'J:charcoal 11 falls into this receiving part and does not go into the warehouse.

Next, to explain the deodorization of the refrigerator equipped with the present invention, the suction passage 10 formed to forcibly draw cold air into the cooler 5 has almost the same odor as that blown into the refrigerator compartment 31+lll by the blower 7. The cold air is sucked in...4. The honeycomb activated carbon of the present invention installed in order to remove odors from the refrigerator compartment is located in the suction passage 10 of A, 11 part i/-2, so this person]' part 1U; 1
The odor contained in the cold air entering from the arrow P2 side is deodorized by 11 parts of light bark activated carbon. In other words, the activated carbon of the present invention deodorizes the odors in the concentrated and flowing cold air. At this time, activated charcoal was used in consideration of the taste.
Although l becomes smaller, if it is moved in the direction where it becomes smaller, the efficiency increases by 1.

〔Effect of the invention〕

As explained above, the present invention provides a refrigerator in which a suction passage for returning cold air from the refrigerator compartment to the cooling compartment is formed in the heat insulating wall that partitions the freezer compartment and the refrigerator compartment. Nicam activated carbon (formed in a Nicam shape with many holes) manufactured by extrusion molding etc. is made so that the frontage of the entrance part is divided, and the passage inside the activated carbon is parallel to the suction passage. Since it is installed with a mounting plate having slits, it is possible not only to improve the space 7 actor but also to obtain an efficient deodorizing effect.

Furthermore, even if the activated carbon weathers and becomes dust, it will be received by the receiving portion 13a, and the dust will not fall into the refrigerator compartment. Furthermore, apply activated carbon to the frontage of the artificial part (L+)
L2 is installed at the y-mouth, and the cold air entering the suction passage 10 is made to pass through the activated carbon part, so that a sufficient deodorizing effect can be obtained in the refrigerator compartment. The low amount of cold air flowing due to this will depend on the diameter of the holes in the activated carbon, but 1
This reduction is almost negligible if the number of holes per square inch is 200 to 600.
