Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a kitchen waste storage with a deodorizing device that uses ozone to remove unpleasant odors from food waste.

BACKGROUND OF THE INVENTION In general, if food waste such as food waste is placed in a storage cabinet and left for two to three days, it will rot and emit a foul odor. The stench fills the kitchen and makes you feel uncomfortable. Moreover, even if such a kitchen waste storage is installed outside, when the lid is opened, the user will feel disgusted and this will seriously impede a comfortable life.

Possible deodorizing methods for removing these odors include a method using an adsorbent such as activated carbon, a method of masking the unpleasant odor with an aromatic agent such as a fragrance, and a method of burning at high temperature. However, methods using adsorbents such as activated carbon have excellent initial deodorizing effects, but are not sustainable, require frequent replacement, and have the problem of high running costs. In addition, the Manoking method, which uses fragrances and other air fresheners, masks the bad odor with another odor, and some individuals may perceive the odor as a bad odor, so it does not eliminate the root cause. . In addition, the high-temperature combustion method requires a large amount of fuel, resulting in very high running costs.The high-temperature process also oxidizes nitrogen in the air, producing toxic nitrogen oxide. was there. In order to solve the above problems, recently, as in Japanese Utility Model Publication No. 60-24351,
A deodorizing method has been devised in which ozone is generated by an ozonizer by applying a high voltage, and ozone is used to oxidize and decompose bad odors.

Problems to be Solved by the Invention However, in the above-mentioned Japanese Utility Model Publication No. 60-24351,
The distance between the ozonizer and the ozone decomposition filter that decomposes excess ozone was small, and ozone and bad odor could not be reacted sufficiently, so the deodorizing effect could not be said to be sufficient.

In view of the above problems, the present invention provides a kitchen waste storage with a deodorizing device that can effectively deodorize food waste.

Means for Solving the Problems In order to solve the above problems, the kitchen waste storage of the present invention includes an ozonizer that applies a high voltage to generate ozone in the storage having an opening/closing lid, and an ozone decomposition filter. The electric fan generates circulating air that is blown from the ozonizer through the ozone decomposition filter into the storage compartment when the lid is opened, and from the ozone decomposition filter to the ozonizer when the lid is closed. This changes the flow of circulating air into the storage room.

Effect: With the above-described configuration, the present invention blows ozone generated by the ozonizer directly into the storage compartment when the opening/closing lid is closed, so that high-concentration ozone comes into contact with bad odors for a long time and has a long time to decompose, thereby deodorizing. The effect will be better. In addition, when the lid is opened, circulating air is generated that blows into the storage through an ozone decomposition filter, which decomposes not only the ozone generated by the ozonizer but also the excess ozone in the storage, resulting in highly concentrated ozone. It is safe to avoid ozone being released into the atmosphere.

Further, numeral 26 is a pressure sensor that detects the weight of the inner box 9, and when food waste is placed in the inner box 9, it is turned on and the entire power circuit is activated.

Furthermore, screens 27 are provided at all entrances to and from the interior 23 of the deodorizing device 16 to prevent dirt from entering. Further, the pedal 4 and the opening/closing lid 2 are connected by two connecting rods, and when the pedal 4 is depressed, the opening/closing lid 2 opens and closes, and at the same time, the first exhaust port 21 closes and the second exhaust The structure is such that the mouth 22 is open, the first intake ports 17, 17' are open, and the second intake ports 18, 18' are closed. Then, when you stop pressing the pedal 4, the open/close cover 2 closes due to its own weight, and at the same time, the first exhaust port 22 opens, the second exhaust port 22 closes, and the first intake port 17°17' opens. closed, and the second intake ports 18, 18' open.

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

First, insert a commercially available polyethylene bag 7 into the inner box 9,
It is fixed with a clamp ring 8 and set in a fixed position inside the kitchen waste storage 1. After passing through the top 7 lunge 6, the opening/closing lid 2 is closed. At this time, even if a power switch (not shown) is turned on, the electric fan 15 and the ozonizer 13 do not operate, and no ozone is generated. The electric fan 15 and the ozonizer 13 are operated only when food waste is put into the interior 6 of the kitchen waste storage 1, that is, the inner box 9, and the pressure sensor 26 located at the outer bottom of the inner box 9 detects the food. I have to. This is done to prevent the ozone concentration from increasing more than necessary when the ozonizer 13 is operated in an empty state or when the humidity is relatively low, and this is done in consideration of safety. Ozonizers usually generate ozone by applying high voltage.
In this case, the amount generated and the speed of decomposition change depending on the humidity, and if even a small amount of kitchen waste is added,
Since the humidity inside the storage 6 is a relative humidity of 80 to 100%, the ozone generation concentration is set according to the humidity at that time.

Therefore, when food is put into the inner box 9, the pressure sensor 2
6 is detected, and the electric fan 15 and ozonizer 13 start operating. At this time, when the opening/closing lid 2 is closed, the first outlet 21 and the second intake ports 18 and 18' are open, so the ozone gas generated in the ozonizer 13 is removed from the second outlet.
The intake ports 18 and 18' are discharged from the exhaust port 21 to the interior 6 of the garbage storage 1 through the electric fan 16, and the ozone decomposition filter 14 does not pass through the high concentration, which is 0.5 in this embodiment. Ozone Ganu, whose concentration is set at ppm to 1 ppm, is directly present on the surface of the food waste and other parts that emit a bad odor, thereby promoting the decomposition of the bad odor. Furthermore, as a way to speed up the decomposition of bad odors, it is possible to install an ultraviolet lamp 29 on the back side of the opening/closing lid 2 and irradiate it.
The moisture on the surface of the food waste accelerates the decomposition of ozone, so there is no need to use an ultraviolet lamp.

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 dielectric electrode 11 as a heater in a separate circuit.

This stabilizes the production of ozone in a humid atmosphere. In this example, the resistance of the heater is 8KQ,
Apply 1 ooV commercial power and set the surface temperature to 40°C.
I got it. The outside temperature at that time was 2°C. The presence of high-concentration ozone in kitchen waste not only decomposes bad odors, but also slows down the speed of spoilage by killing bacteria on the surface of the food.

Next, when the pedal 4 is pushed in and the opening/closing lid 2 connected by the connecting rod 28 is opened, the first intake port 17°17' and the second
The exhaust port 22 opens, and the first exhaust port 21 and the second intake port 18
, 18' are closed, the bad odor in the interior 6 of the kitchen waste storage 1 is sucked in through the first intake ports 17 and 17', and is sent into the interior 23 of the deodorizing device 16 through the second exhaust port 21. Therefore, the ozone decomposition filter 1 is
4, it flows back into the interior 6 of the kitchen waste storage 1 and is circulated, but since the bad odor generally flows down the wall, the bad odor once flows into the downward U-shaped groove formed by the totsubu 7 lunge 5. 24, so the first intake port 1 linked to it
7. 17' The bad odor will be collected more efficiently)
This is to prevent the food from leaking out of the kitchen waste storage 1 as much as possible.

When the opening/closing lid 2 is opened in this way, the first intake port 17
, 17', not only the bad odor but also the excess ozone is sucked in, so that the emission of ozone can be minimized.

In this example, the direction of the circulating air inside the deodorizing device was changed by opening and closing the intake and exhaust ports, but the rotation of the electric fan was reversed, and the rotation of the intake fan, exhaust fan, and two fans were changed. There is no problem in using this, and the present invention is characterized in that the direction of the circulating air in the deodorizing device is changed by interlocking the opening and closing of the lid.

Further, as a method for detecting the no-load state inside the inner box, it is also possible to apply a humidity sensor instead of a pressure sensor.

Effects of the Invention As described above, the present invention includes a deodorizing device having an ozonizer that generates ozone by applying a high voltage, an ozone decomposition filter, and an electric fan in a storage having an opening/closing lid. An electric fan generates circulating air that blows out from the ozonizer through the ozone decomposition filter into the storage when the lid is opened, and changes to circulating air that blows out from the ozone decomposition filter into the storage through the ozonizer when the lid is closed. This garbage storage with a deodorizing device is characterized by a good deodorizing effect, long-lasting performance, and no need for maintenance.
