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]

Refrigerators contain odors because they store a variety of foods. Users place activated charcoal in a corner of their refrigerators to remove this odor. However, the above activated carbon usually
Since granular activated carbon is packed in a container, the surface area of each individual granular activated carbon cannot completely contribute to odor removal. In addition, this method has the drawback that a part of the inside of the refrigerator is cut out to install the activated carbon, even if it is only in one corner.

Examples of refrigerators related to this type include:
No. 111951 is mentioned.

[Purpose of the invention]

In order to improve the above-mentioned defects, the present invention replaces the conventional granular activated carbon with honeycomb-shaped activated carbon formed by extrusion molding or the like, and the activated carbon is installed in a heat insulating wall that separates the freezing and refrigerating compartments. It is installed in the cold air suction oil passage to improve the space factor and to obtain an efficient deodorizing effect.

[Summary of the invention] That is, when placing honeycomb activated carbon (having a large number of holes formed in a honeycomb shape) made by extrusion molding etc. in the artificial part of the suction passage formed in the heat insulating wall, the side It is designed to be installed in the top opening of a box-shaped fixture with ventilation holes in the wall.

[Embodiments of the invention]

The details of the present invention will be explained below with reference to an embodiment shown in FIGS. 1 and 2. Reference numeral 1 denotes a refrigerator main body, and 2.3 represents a freezing compartment and a refrigerating compartment formed inside the refrigerator main body 1. 4 is an insulating wall that partitions the freezer compartment 2 and the refrigerator compartment 3; 5 is a cooler installed at the back of the freezer compartment 2; 6 is cold air cooled by the cooler 5 to the freezer compartment 2 and the refrigerator compartment 3; A fan guard 7 is installed in front of the cooling chamber 8 in which the cooler 5 and the like are installed. 9 is a passage that returns the cold air in the freezer compartment 2 to the cooler 5; 10 is a passage that returns the cold air in the refrigerator compartment 3 to the cooler 5;
This is the suction passage that returns the Reference numeral 10a designates an entrance space of the suction passage 10 which is open at the bottom, and is a space in which a deodorizing device, which will be described later, is to be housed. Reference numeral 11 denotes a box-shaped fixture that is open at the top and has ventilation holes 11a on the side wall surface, and on the upper open surface is activated carbon 12 formed by extruding a large number of holes into a honeycomb shape using coconut shell or the like as a raw material. is set up. Also, mounting legs 11b are appropriately provided around the box-shaped fixture 11, and the box-shaped fixture 11 is locked with the mounting legs 11b to the lower opening of the inlet space 10a of the suction passage 10. has been done. Further, all the powder generated by the weathering of the activated carbon 12 is stopped at the bottom surface 11C of the box-shaped fixture 11 to prevent it from falling into the refrigerator. Further, the box-shaped fixture 11 is housed within the entrance space 10a of the suction passage 10 without extending beyond the ceiling surface of the refrigerator compartment 3 toward the inside of the refrigerator.

To explain the deodorizing effect of the deodorizing device configured as described above, it is said that the suction passage 10 formed to forcibly suck cold air into the cooler 5 side is blown out to the refrigerator compartment 3 side by the blower 7. The same amount of cold air is sucked in. The honeycomb activated carbon according to the present invention is installed in the inlet space 10a of the suction passage 10 to remove odors in the refrigerator compartment 3. Through the ventilation holes provided, and honeycomb activated carbon 1
By passing through all of the ventilation holes No. 2, the odors contained in the cold air can be efficiently deodorized with 12 parts of the honeycomb activated carbon. In other words, the activated carbon of the present invention efficiently deodorizes the concentrated and flowing cold air.

〔Effect of the invention〕

As explained above, the present invention forms a suction passage for returning cold air from the refrigerator compartment to the cooling chamber in the heat insulating wall that partitions the freezer compartment and the refrigerator compartment, and installs activated carbon having honeycomb-shaped ventilation holes in the suction passage. In a refrigerator designed like this, the top is open,
Appropriately around the box-shaped fixture with ventilation holes on the side wall.
In addition to providing mounting legs, the top opening of the box-shaped fixture is
Activated carbon having honeycomb-shaped ventilation holes is installed in order to pass the cold air sucked into the refrigerator from the ventilation holes provided on the side wall surface of the box-shaped fixture, and in this state, the box-shaped fixture is Since it is installed with the mounting legs in the entrance space of the cold air suction passage, the activated carbon powder generated by weathering is securely caught at the bottom of the box-shaped fixture without falling into the inside of the refrigerator, and the interior of the refrigerator is It can prevent it from getting dirty.

In addition, most of the cold air sucked into the cold air suction passage passes through the activated carbon honeycomb-shaped ventilation holes, which allows the activated carbon to efficiently adsorb odors contained in the cold air. As a result, an extremely efficient deodorizing effect can be obtained.

Furthermore, by storing and installing a box-shaped fixture made of activated carbon in the space that forms the entrance of the cold air suction passage, the space required to install the deodorizing device is reduced without reducing the internal volume of the refrigerator. good (something that can be done)
