Abstract

PURPOSE:To prevent leakage of ozone by composing a device of a pressing plate having equivalent elasticity to rubber which is easily degraded by ozone and a spring switch which is reset naturally, and using the tensile elasticity of the pressing plate to install the spring switch under the input condition. CONSTITUTION:A device is composed of a pressing plate 16 having equivalent elasticity to rubber which is easily degraded by ozone and a spring switch 17 which is reset naturally, and the tensile elasticity of the pressing plate 16 is used to install the spring switch under the input condition. When ozone is mixed in the atmosphere where a fuse is located, the pressing plate is degraded by the ozone to generate the crazing, but the pressing plate 16 is broken because of the tensile elastic force applied thereto, and the spring switch 17 pressed with the pressing plate 16 and left under the input condition is reset naturally to be under the open condition. Namely, when the ozone is leaked, a fuse 18 detects the ozone to stop an ozone type deodorizer by connecting the spring switch 17 to an input power source of the ozone type deodorizer. Leakage of the ozone at high density can be thereby prevented to improve the safety.

Description

[Detailed Description of the Invention] Industrial Field of Application The present invention is designed to ensure the safety of a deodorizer that uses ozone to remove unpleasant odors from kitchen storage areas that store food waste, etc. Regarding fuses. BACKGROUND OF THE INVENTION In general, if food waste such as kitchen waste from eating habits is placed in a storage cabinet and left for two to three days, it will begin to rot and emit a foul odor. The stench fills the kitchen and makes you feel uncomfortable.Also, even if you leave such a kitchen cabinet outside, when you open the lid, it emits a bad odor and makes you feel disgusted, making it difficult to live a comfortable life. create a cause that significantly inhibits

Possible deodorizing methods to remove these odors include methods using adsorbents such as activated carbon, methods that mask the unpleasant odors with aromatics such as fragrances, and methods that involve burning at high temperatures.

However, although methods using adsorbents such as activated carbon have excellent initial deodorizing effects, they are not sustainable and require frequent replacement with new adsorbents, resulting in high running costs and labor. I had an issue.

Furthermore, masking methods using aromatic agents such as fragrances mask the odor with another odor, and some individuals may perceive the odor as a foul odor, and the underlying cause has not been resolved.

In addition, the method of burning at high temperatures requires a large amount of fuel, resulting in very high running costs, and the high temperature process also oxidizes nitrogen in the air, producing toxic nitrogen acids and arsenics. Problems such as 3! There was a problem.

In order to solve the above problems, recently
As in Publication No. 351, ozone is generated by an ozonizer by applying a high voltage, and odor is oxidized and decomposed by ozone.
A method of deodorizing has been devised.

Problems to be Solved by the Invention However, in the above-mentioned Japanese Utility Model Publication No. 60-24351, when the ozone decomposition ability of the ozone decomposition catalyst decreases, excess ozone leaks out of the deodorizer. Not only does ozone emit a unique odor, but when the concentration exceeds 0.1 ppm, it can damage the eyes and respiratory organs and have a negative impact on the human body. In other words, there is a risk that ozone may leak out of the deodorizer, and no consideration has been given to safety.

In view of the above problems, the present invention has been developed to solve the following problems: When the ozone decomposition ability of the ozone decomposition catalyst decreases and excessive ozone is generated and leakage occurs,
It provides a fuse that detects the ozone and turns off the power to the ozonizer.

Means for Solving the Problems In order to solve the above problems, the fuse of the present invention consists of a holding plate that is easily deteriorated by ozone and has rubber elasticity, and a spring switch that returns naturally. The spring switch is installed in the input state using tensile elastic force.

According to the above structure, when ozone is mixed in the atmosphere in which the fuse is installed, the holding plate deteriorates due to the ozone and crazing occurs, and this holding plate breaks due to the tensile elastic force applied thereto. The spring switch, which was pressed by the holding plate and was in the input state, returns naturally and becomes open. That is, by connecting the spring switch to the input power source of the ozone deodorizer, when ozone leaks, the fuse detects the ozone and stops the ozone deodorizer. Therefore, high concentration ozone is prevented from leaking and safety is improved.

EXAMPLE Hereinafter, an ozone type deodorizing kitchen storage cabinet equipped with a fuse according to an embodiment of the present invention will be described with reference to FIGS. 1 to 3.

Reference numeral 1 denotes a storage with a deodorizing function, which is composed of an opening/closing lid 3 that opens and closes an opening 2, an outer box 4, and a top flange 5.

A commercially available polyethylene bag 7 is placed in the interior 6 of this kitchen storage 1.
The inserted inner box 9 and the dielectric 1 are fixed with a clamp ring.
Alumina is used as Z r on the discharge electrode 11 side.
A zonizer 13 using B2 material, a ruthenia material that also serves as a heater for the induction electrode 12, and an ozone decomposition catalyst 1 that also serves as a deodorizer and whose main components are titanium oxide and manganese oxide.
4, an exhaust fan 15, a presser plate 16 with rubber elasticity that easily deteriorates due to ozone, and a fuse 18 consisting of a spring switch 17 that returns naturally.
Note that the zonizer 13 is electrically connected to a high voltage generator 19, so that an AC high voltage is applied between the discharge electrode 11 and the induction electrode 12. The induction electrode 12 is connected to the ground side, and by applying a voltage of about 100V in a separate circuit, it can also be used as a heater.

The resistance value of the heater at this time was set to about 8KΩ, and the surface temperature was set to about 40°C.

Further, the fuse 18 is arranged in the primary power supply circuit of the high voltage generator 19, and is installed between the ozone decomposition catalyst 1.t and the exhaust fan 15.

Furthermore, a screen 22 for preventing dust from entering is provided at the air intake port 21 to the ozone generator 20 in which the ozonizer 18 is incorporated.

A small intake fan 23 is attached to the center of the open/close N3, which sucks outside air through the intake port 24 and blows the outside air to the food items placed in the bottom of the polyethylene bag 7 of the inner box 9. It is set as. Furthermore, by forming a flange edge 25 narrower than the opening edge of the inner box 9, the top flange 5 allows the intake air to pass through the duct 2C formed by the inner box 9 and the outer box 4. It is designed to lead to the mouth 21. Note that 27 is a power cord.

The operation of the deodorizing storage 1 constructed as described above will be described below with reference to FIGS. 1 to 3.

First, insert the commercially available polyethylene bag 7e into the inner box 9,
It is stopped with the crumbling ring 8 and set in a fixed position inside the storage cabinet 1 with a deodorizing function. Then, fold down the top flange 5 and close the opening/closing M3. Next, plug in the power cord 27,
Intake fan 23, exhaust fan 15, and ozonizer 1
Operate 8.

Therefore, when food items are placed in the inner box 9, the intake fan 23
Outside air is sucked in through the suction port 24 and blown onto the food items placed in the bottom of the polyethylene bag 7 of the inner box 9. Cooking products usually undergo rotting and fermentation due to oxidation and bacteria, resulting in bad odors. Moisture is essential for this rotting and fermentation, and humid conditions promote the occurrence of bad odors. However, as mentioned above, when the intake fan 23 sucks relatively dry outside air into the inside 6 and blows it onto the surface of the food, not only does the temperature of the inside 6 decrease, but the surface of the food It dries and forms a dry film, which also has the effect of suppressing bad odors from kitchen products.

The outside air blown onto the surface of the food items rises along the side wall of the inner box 9 along the opening edge, passes through the inside of the flange edge 25 and the duct 26, and enters the ozone generator 20 through the intake port 21. Inside the ozone generator 20, ozone and mixed gas generated from the ozonizer 18 to which a high voltage is applied by the high voltage generator 19 are collected. Ozone and odor react even in a mixed gas, oxidizing the odor and changing it to something with less odor.
Generally, reactions in gas mixtures are slow. The deodorizing effect of ozone is achieved when ozone is decomposed into oxygen and oxygen radicals, and the oxygen radicals react with malodorous components.

Therefore, most of the deodorization takes place on the surface of the ozone decomposition catalyst 14. Moreover, since excess ozone is decomposed by the catalyst 14 and changed into oxygen, no ozone remains in the gas exhausted by the exhaust fan 15. However, if exposed to ozone for a long time, the ozone resolution deteriorates over time, and a small amount of ozone will remain in the exhausted gas. The resolution life varies depending on ozone concentration, odor concentration, temperature, and humidity, and is therefore affected by usage conditions. Ozone not only emits its own odor, but also Ozone. If the concentration exceeds 1 ppm, it will damage the eyes and respiratory organs and have an adverse effect on the human body. Therefore, it is necessary to suppress ozone leakage as much as possible, but in the case of the present invention, it is possible to turn off the power to the high voltage generator 19 using the fuse 18 installed between the ozone decomposition catalyst 14 and the exhaust fan 15. This prevents ozone leakage and maintains safety.

Furthermore, since the discharge of the ozonizer 13 tends to become unstable in a humid atmosphere, it is necessary to heat the surface of the ozonizer 13 by applying a voltage that uses the induction electrode 11 as a heater in a separate circuit.

This prevents dew condensation on the electrode surface and stabilizes ozone production in a humid atmosphere. In this example, the resistance of the heater was set to 8KΩ, and a commercial power source of IOOV was applied to obtain a surface temperature of 40°C. The outside temperature at that time was 20°C.

Normally, in the case of an ozonizer that generates ozone by applying a high voltage, the amount of ozone generated changes depending on the temperature and humidity at the time. That is, when a high voltage generator that generates a constant high voltage is used, the ozone concentration changes significantly depending on temperature and humidity, and the concentration change is about three times that in summer and winter. This excess ozone shortens the life of the ozone decomposition catalyst and increases the probability that ozone will leak outside the storage.

In one embodiment of the present invention, a fuse 18 is installed between the ozone decomposition catalyst 14 and the exhaust fan 15, so that even if the ozone passes through without being decomposed by the ozone decomposition catalyst 14, the ozone will be stored. The high voltage power supply 19 is stopped in order to stop the generation of ozone so as not to leak outside the refrigerator. This fuse 18 is installed by applying a tensile elastic force to a flexible holding plate 16 such as NBR, which easily deteriorates due to ozone, and holding down the spring switch 17 which returns naturally, so if ozone passes through, the holding plate will deteriorate. As a result, the spring switch 17 returns to its natural state, that is, returns to the OFF state and the connected high-voltage power switch 19 stops.

Next, when the opening M3 is opened, the intake fan 23 stops. Although this has been dried and the concentration has become low, the 6
This is to avoid stirring up the bad odor and scattering it from the opening 2. However, since the exhaust fan 15 continues to operate, the pressure inside the refrigerator 6 is reduced, and outside air is introduced through the opening 2.
Along with most of the bad odor inside the refrigerator 6, the duct 2 passes from the opening edge of the inner box 9 through the inside of the flange edge 25 of the top 7 flange 5.
It enters the intake port 21 from 6. Therefore, scattering of bad odor from the opening 2 can be avoided as much as possible. In this example, the displacement was 30 L/min.

Effects of the Invention As described above, the fuse of the present invention consists of a pressing plate with rubber elasticity that is easily deteriorated by ozone, and a spring switch that returns to its original position naturally. This fuse is installed in the input state, and by placing this fuse in a high voltage power supply and installing it behind the ozone decomposition catalyst of the ozone type deodorization, ozone will pass through and pose a safety problem. When this occurs, the power supply is shut off, completely preventing ozone leakage.
