てきている。2. Description of the Related Art Conventionally, activated carbon has been mainly used as an adsorbent for removing odorous components existing in a limited space such as a refrigerator. However, the adsorbing capacity of activated carbon is naturally limited, and in order to recover the adsorbing ability, heat has been applied, and ultraviolet rays have been irradiated in the presence of a photocatalyst.

らに取り扱い容易で、高性能のものが要望されている。It can be considered that odorous foods are stored in the refrigerator, or foods stored for a long period of time are deteriorated or deteriorated, and the odorous components always exist at a certain level. Conventionally, activated carbon that has been generally used as a deodorant has a limited adsorption capacity, and some kind of regeneration is required. Further, a method of deodorizing and sterilizing the inside of the refrigerator has been proposed, but it cannot be said that it is practically simple, and it is desired that it be easy to handle and have high performance.

It is to provide a freezer-refrigerator equipped with an antibacterial device. As a result of various experimental studies, the present inventors have found that by using a catalytic deodorant instead of activated carbon, the mechanism becomes extremely simple and can be used maintenance-free for a long period of time. Also, if fine dust, bacteria and mold spores floating with dust in the refrigerator can be removed by a filter with low draft resistance, the inside of the refrigerator can be cleaned and the effect of microorganisms on food storage can be reduced. It can be stored for a long period of time and can be attached to a wide range of models by integrating deodorizing and antibacterial agents into a cassette type, and even if the deodorizing catalyst is damaged, the antibacterial filter acts as a saucer. I also gained knowledge. The present invention has been made based on the findings obtained by such an experimental study.

合せて脱臭、抗菌を同時に行なうことができる。[Means for Solving the Problems] That is, the findings obtained by the experiments conducted by the present inventors will be described more specifically below. Most of the odorous components in refrigerators are sulfur-based gas based on the actual survey, and methyl mercaptan is the main component. Among transition metal oxides, methyl mercaptan undergoes a dehydrogenation reaction when it comes into contact with a manganese-based catalyst, and is converted to dimethyl sulfide having a low odor intensity. Therefore, if the manganese-based catalyst is formed into, for example, a honeycomb shape so as to make good contact with the air, and the air in the refrigerator is allowed to pass through the manganese-based catalyst, efficient deodorization becomes possible for a long period of time. In addition, bacteria and mold spores in the atmosphere are said to be suspended in the form of dust and dust, and a filter with a shape that allows good air contact is placed in the ventilation passage in the refrigerator. A silver compound is supported on this, and the antibacterial property of silver ions is utilized,
Try to sterilize the bacteria on the filter. In addition,
Examples of the material of the filter in this case include nonwoven fabric of synthetic fibers such as polyester, silica, and alumina-based ceramics. In addition, by adjusting the basis weight of the non-woven fabric, the flow of air can be secured without making small holes in the filter, and it also serves as a saucer due to damage to the deodorizing catalyst, preventing scattering into the refrigerating room and combining with the deodorizing filter. Deodorization and antibacterial can be performed simultaneously.

できる。Further, since the antibacterial filter uses silver and a silver compound, there is a problem that the antibacterial filter reacts with sulfide gas, ultraviolet rays, etc., and there is no problem in the performance of the filter, but the color changes. Therefore, the color change can be suppressed to some extent by coloring black or brown in advance. Further, by providing bypasses on both sides of the cassette type deodorizing and antibacterial device so as not to affect even if clogging of the antibacterial device occurs, insufficient cooling in the refrigerating chamber can be solved.

The object is to carry a deodorizing filter carrying an oxide of a transition metal element as a catalyst component and an inorganic material containing silver or a silver compound. This is achieved by a freezer-refrigerator equipped with a deodorizing / antibacterial device in which a deodorizing / antibacterial device constituted by facing and combining with the antibacterial filter described above is arranged at a cool air return suction port in a refrigerating chamber.

It is composed of an oxide of MnO 2 and works effectively as a deodorizing catalyst. That is, a manganese compound or iron oxide,
When a mixture of copper oxide is kneaded with, for example, zeolite, silica, or alumina to form a porous ceramic filter and brought into contact with the atmosphere in the refrigerator, methyl mercaptan, which is the main component of odor, and hydrogen sulfide have the following formula (1) ),
As shown in (2), it chemically changes to dimethyl sulfide and sulfur, respectively, and the odor intensity is greatly reduced.

小限に抑えることができる。## STR00002 ## H 2 S → S + H 2 (2) On the other hand, the antibacterial action of silver and silver compounds as an antibacterial filter has been known for a long time. For example, silicon such as zeolite, aluminum, When a part of sodium in the porous material containing an oxide such as sodium as a main component is replaced with silver, the antibacterial property is further enhanced.
From these facts, a silver-containing ceramic or non-woven fabric filter is installed in the air passage of the cool air return suction port in the refrigerating room, and if dust and dust containing bacteria and mold spores are attached to the filter, Microorganisms will die over time. There is a theory that an electrochemical action occurs between silver ions and microorganisms, or a theory that silver ions bind to proteins in the cells of microorganisms and cause growth inhibition. Since this antibacterial filter carries silver and a silver compound, the antibacterial filter is discolored by the sulfur gas, which is the fate of silver, and ultraviolet rays. Although this discoloration does not actually impair the performance of the filter, it may be misidentified by the user, so if there is a problem in appearance, for example black, red, brown,
Coloring can be minimized by coloring with a predetermined pigment such as gray.

はさみ込みカセットタイプの脱臭−抗菌装置となる。FIG. 2 is an enlarged cross-sectional view of a cassette type deodorizing / antibacterial device to be attached to the portion A of FIG. Reference numeral 9 is a manganese-based deodorizing catalyst which constitutes a deodorizing filter. As a catalyst used for the oxidation or dehydrogenation reaction, a manganese compound or a mixture of iron oxide and copper oxide is kneaded with, for example, zeolite, silica or alumina. , And formed into a honeycomb-shaped porous ceramic filter. When this catalyst is brought into contact with the atmosphere in the refrigerator, methyl mercaptan and hydrogen sulfide gas, which are the main components of the odor, chemically change as shown in the above formulas (1) and (2), and change to dimethyl sulfide and sulfur, respectively. However, the odor intensity is greatly reduced. Reference numeral 10 denotes a buffer belt for protecting the periphery of the honeycomb-shaped manganese-based catalyst, and the material thereof is soft maltoprene or the like for protection. Reference numeral 11 is an antibacterial filter carrying silver and a silver compound. For example, when a part of sodium in a porous material mainly composed of oxides such as silicon, aluminum and sodium such as zeolite is replaced with silver, antibacterial property is obtained. Is even higher. From these facts, the silver-containing antibacterial filter 11 allows dust and dirt containing bacteria and mold spores to adhere, and the microorganisms will die over time. Reference numeral 12 is a lower case of the deodorizing-antibacterial device cassette, 13 is an upper case of the deodorizing-antibacterial device cassette, and the manganese-based deodorizing catalyst 9 and the antibacterial filter 11 are sandwiched between the lower case 12a and the upper case. It becomes a cassette type deodorizing-antibacterial device.

とができる。FIG. 4 is a perspective view of the external appearance of the antibacterial filter 11. As the material of the antibacterial filter 11, a synthetic fiber non-woven fabric such as polyethylene or a ceramic material such as silica or alumina is practical, and the cooling power of the refrigerating chamber 4 is practical. (When the density becomes extremely large, the ventilation resistance becomes large and the cooling power decreases due to the same cause as that of clogging), and when the deodorizing catalyst 9 is damaged, it does not fall into the refrigerating chamber 4, so that the antibacterial filter 11 is considered. The weight per unit area is adjusted to 170 ± 30 g / m 2 . Further, since the antibacterial filter 11 carries silver and a silver compound, it is discolored by sulfide gas, ultraviolet rays, etc. Therefore, it is preliminarily colored in a predetermined color such as black, brown, red or gray in consideration of its appearance. This will prevent discoloration to some extent.
