Description

[Detailed description of the invention] This invention relates to a refrigerator deodorizer that deodorizes odors emitted from food stored in the refrigerator.

As is well known, refrigerators store various foods such as fresh fish, vegetables, and meat at low temperatures. It may cause the odor to stick to food or cause discomfort when the refrigerator is opened. In order to prevent such discomfort caused by food odors inside the refrigerator, deodorizers that utilize the odor absorbing properties of activated carbon or the like have been commonly used.

This invention is a refrigerator deodorizer that uses a completely new solid deodorizer, which the creator of this application previously proposed in Japanese Patent Application No. 1095-1985, in place of the conventional deodorizer that uses activated carbon or the like. The purpose is to provide equipment. That is, since this deodorizing agent is completely new, this invention was made in view of the fact that no equipment has been developed for deodorizing the inside of a refrigerator using this deodorizing agent.

The above-mentioned solid deodorizer previously proposed by the inventor of this application is made by adding an aqueous solution to a humic plant. Humic plants are those in which humus contains humus precursors or humus in humus precursors, and in either case, it contains a large amount of humus precursors. This humic precursor is an intermediate product in the transformation process of organic matter leading to humus, and contains metabolites by aerobic bacteria and facultative anaerobic bacteria, and trace amounts of inorganic components such as silicic acid and iron. This metabolite is a mixture of compounds with exposed phenol groups, oxidizing enzymes such as phenol oxidase, or quinones, polysaccharides, amino acids, etc. that are oxidized products of phenol compounds. When water or the like is added to such humic plants, the humic precursors contained in the humic plants are activated. When odor, which is an organic volatile component, comes into contact with or mixes with this, a polycondensation reaction for humification occurs due to metabolites in the humic precursor, inorganic substances such as silicic acid, and organic substances, and the organic volatile component The molecular weight is increased to prevent volatilization and fixation, thereby preventing odor emission, that is, obtaining a deodorizing effect. This immobilization does not inhibit the progress of the enzymatic reaction. As a form of utilization of such humic plants, the humic plants are immersed in water to elute the humic precursors necessary for deodorization and evaporate into the air together with the water molecules, thereby emitting them into the air. There is a form of use that immobilizes odor components.

This invention provides a device that embodies this type of usage inside a refrigerator.

Examples of this invention will be described below based on the drawings.

The refrigerator deodorizer 1 of this embodiment is composed of a main body frame 2 and a water tank 3. The main body frame 2 is made up of a bottom part 4 on which the aquarium 3 is placed, a head part 5 which houses the driving device, and a support part 6 which connects the bottom part 4 and the head part 5. The bottom portion 4 is a flat plate having a shape similar to the outer peripheral shape of the water tank 3, and the bottom portion 4 is a flat plate having a shape similar to the outer peripheral shape of the water tank 3.
A protrusion 7 is provided to prevent the material from falling from around the bottom portion 4. The head 5 is connected to the bottom 4
It consists of a box fixed above the support part 6 with an interval slightly larger than the height of the water tank 3. The head 5 can be opened and closed by a lid 8, and inside thereof there is a power source 9 such as a battery, an oscillation circuit 11 electrically connected to the power source 9 via a switch 10, and a power source 9 such as a battery. An electromagnet 12 connected to an oscillation circuit 11 and a diaphragm 14 whose substantially central portion is fixed to a support plate 13 facing the bottom 4 constituting the head 5 and whose lower end hangs directly below are housed. This diaphragm 14 is made of a thin metal plate, and its upper end is provided so as to face the electromagnet 12.

Inside the circumferential wall 15 of the water tank 3, partition frames 1 made of wire mesh or porous material are installed at predetermined intervals.
6 is provided, and this peripheral side wall 15 and the partition frame 1
A humic plant A is stored between the tanks 6 and 3, and water is poured into the water tank 3.

Next, the use of the refrigerator deodorizer of this embodiment having the above configuration will be explained.

First, after storing a predetermined amount of humus A between the circumferential wall 15 and the partition frame 16 of the water tank 3, water is injected to a predetermined water level. The lower end of the diaphragm 14 is connected to the water tank 3.
After the water tank 3 is placed on the bottom part 4 of the main body frame 2 so as to be located in the center of the refrigerator, the water tank 3 is stored in the refrigerator. When the switch 10 is turned on after completing these preparations, the electromagnet 12 is intermittently excited by the current flowing from the power source 9 through the oscillation circuit, causing the diaphragm 14 to vibrate, causing the water in the water tank 3 to It vibrates and stimulates the humic plant A, causing the deodorizing components contained within the humic plant A to be eluted. At the same time, since it promotes the evaporation of water from the water surface, more deodorizing components are scattered into the air for the reasons mentioned above, increasing the molecular weight of odoriferous organic volatile components.
This makes it possible to prevent odors from escaping by preventing volatilization and fixing them. Although the switch 10 is manually input in the illustrated embodiment,
If necessary, other types of switch mechanisms may be used, such as one that is activated when the refrigerator door is opened and closed, or one that is activated at predetermined intervals by a timer.
Furthermore, although the power source 9 is a portable one that uses a battery, it is of course possible to use a household alternating current. When batteries are used, they can be replaced by opening the lid 8 of the head 5.

As is clear from the above description, the refrigerator deodorizer of this invention can effectively eliminate odors inside the refrigerator.
