Description

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

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.
Even if such a kitchen waste storage is installed outside, the user will feel disgusted when the lid is opened, which will seriously impede a comfortable life. As deodorizing methods for removing these bad odors, there are methods using adsorbents such as activated carbon, methods of masking unpleasant odors with aromatics such as fragrances, and methods of burning at high temperatures. 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, masking methods using fragrances and other fragrances mask the bad odor with other odors, and some individuals may perceive the odor as a bad odor, so it does not eliminate the root cause. . Also, go to 3, which burns at high temperatures.

This method requires a large amount of fuel, resulting in very high running costs, and also has problems and problems, such as processing at high temperatures, which oxidizes even nitrogen in the air, producing toxic nitrogen oxides. Ta. In order to solve the above problems, a method has recently been considered, as disclosed in Japanese Patent Application Laid-Open No. 63-57401, in which ozone is generated by an ozonizer by applying a high voltage, and the odor is oxidized and decomposed by ozone to deodorize it. ing.

However, in the above-mentioned Japanese Patent Application Laid-Open No. 63-57401,
Because the conditions inside the kitchen waste storage are room temperature and humid,
A high concentration of malodorous components is generated, and a small amount of ozone is generated from the ozonizer under humid conditions, so that a sufficient deodorizing effect cannot be obtained. In addition, in the initial stage, activated carbon used as an ozone decomposer has a deodorizing effect, which reduces odor, but only has a short lifespan.

In view of the above problems, the present invention provides a kitchen waste storage with a deodorizing device that can effectively deodorize garbage for a long period of time.

Means for Solving the Problems In order to solve the above problems, the kitchen waste storage with a deodorizing function of the present invention has an inner box for storing kitchen waste, and a removable container having a suction groove located on the inner periphery of the opening of the inner box. possible flange duct and
It consists of an outer lid that opens and closes the inner box opening, an ozonizer that applies high voltage to generate ozone, a catalyst that deodorizes and decomposes ozone, and an exhaust fan. Ozonizer from the suction groove of the flange duct
This kitchen waste storage is characterized by exhausting air to the outside through a catalyst and a catalyst.

Effect of the present invention With the above-described configuration, the bad odor is diluted by the outside air flowing into the inner box storage by exhaust gas, and the ozonizer and
A catalyst that functions both for deodorization and ozone decomposition sufficiently separates bad odors to obtain a deodorizing effect. In addition, the bad odor adsorbed within the catalyst is also decomposed by ozone, so the deodorizing effect can be maintained for a long period of time. Furthermore, the concentration of malodorous components inside the inner box is diluted, and the inside of the inner box becomes negative pressure due to exhaust gas, so even when the outer lid is opened, unpleasant odors are released outside the storage box. This can be avoided as much as possible.

EXAMPLE Hereinafter, a kitchen waste storage with a deodorizing function according to an example of the present invention will be described with reference to FIGS. 1 to 6.

1 is an inner box 3 having an opening 2 for storing kitchen waste, a flange duct 6 having a suction groove 4 and a hollow part 5 located around the entire circumference of the entrance part 2 of the inner box 3, and an outer box having an intake lower. This is a kitchen waste storage with a deodorizing function, which is composed of a lid 8 and an outer box 9.

Inside the kitchen waste storage 1, a commercially available polyethylene bag 11 with a carrier wire 10 is secured with a clamp ring 12 and inserted into an inner box 3, alumina is used as a dielectric (not shown), and a discharge electrode (not shown) is used. Ozonizer-16 uses borated zirconia material on the (not shown) side and ruthenia material that also serves as a heater for the induction electrode (not shown), and an ozonizer that also serves as deodorization and has titanium oxide and manganese oxide as its main components. It is composed of a catalyst 17 and an exhaust fan 186.
,.

Ru.

In addition, the outer lid 8 is arranged around the inner hinge 19,
It opens and closes by pushing L'20 up and down and by operating the connecting rod 21.

22 is an air passage connecting the hollow part 6 of the flange duct 6 and the deodorizing device part 23, and the gas in the inner box 3 is removed by the exhaust fan 18.
The air enters the hollow part 5 from the suction groove 4 of the seven-lunge duct 6 located around the entire circumference of the opening 2 of the inner box 3, passes through the connecting port 24, the air passage 22, and further passes through the ozonizer 16 and the catalyst 17. Excretion, put out.

The ozonizer 16 is electrically connected to the high voltage generator 26, and an alternating current voltage of approximately eKV and 18KH is applied between the discharge electrode (not shown) and the induction electrode (not shown). It looks like it will be done. Further, the induction electrode (not shown) side is connected to the ground side, and by applying an AC voltage of about 10 ov through a column circuit, it can also be used as a heater. The resistance value of the heater at this time was set to about 8 Ω, and the surface temperature was set to about 40C.

In addition, a lip 27 is formed on the inner box 3 side of the flange duct 6 at a predetermined position corresponding to the periphery of the opening 2 of the inner box 3, and extends in parallel at an interval larger than the thickness of the end 26 of the inner box 3. has been done. This lip 27 plays the role of fixing the extra lugs of the polyethylene bag 11 when the inner box 3 to which the polyethylene bag 11 is attached is set at a predetermined position in the storage 1. The flange duct 6 rotates around an outer hinge 28 of the outer box 9 to open and close, and 29 is a handle for opening and closing the duct.

When the seven-lunge duct 6 is closed, the connection port 24 is connected to the air passage 22. The outer cover 8 opens and closes around an inner hinge 19 that is integrated with the flange duct 6, and has an intake lower, and when the inside of the inner box 3 becomes negative pressure, outside air is introduced through the intake port T.

The operation of the deodorizing kitchen waste storage 1 constructed as described above will be explained below with reference to FIGS. 1 to 5.

First, a commercially available polyethylene bag 11 is inserted into the inner box 3, the remaining bag 11 is wrapped around the clamp ring 12, and fixed to the end 26 of the inner box 3.

The inner box 3 is lifted with a carrier wire 10, set at a fixed position inside the kitchen waste storage 1, the flange duct 6 is knocked down, and the outer lid 8 is closed.

At this time, the lip 27 of the flange duct 6 acts to press the end of the polyethylene bag 11 onto the end 26 of the inner box 3. Furthermore, the connection port 24 is coupled to the air passage 22 .

Next, the 1 oov commercial power supply kitchen garbage storage 1 is plugged in, and the ozonizer 16 and exhaust fan 18 are activated. At this time, the gas inside the inner box 3 enters the hollow part 5 from the suction groove 4 of the flange duct 6 located on the inner periphery of the opening 2 of the inner box 3 by the exhaust fan 18, and flows through the connecting port 24 and the air path. 22, and is further discharged through an ozonizer 16 and a catalyst 17.

Therefore, outside air is drawn into the inside of the inner box 3, which has a negative pressure, through the intake lower formed in the outer lid 8, and the bad odor generated from the kitchen waste is diluted. Further, due to the intake air, outside air reaches the kitchen waste placed in the bottom of the inner box 3 through the trench. Kitchen waste usually undergoes oxidation and bacterial decomposition and fermentation, producing a foul odor. Moisture is essential for this rotting and fermentation, and high humidity97 conditions promote the occurrence of bad odors. However, as mentioned above, drawing relatively dry outside air into the refrigerator and blowing it over the surface of the food waste not only reduces the humidity inside the refrigerator, but also
The surface of the kitchen waste dries and forms a dry film, which also has the effect of suppressing bad odors coming from inside the kitchen waste.

The outside air blown onto the surface of the kitchen waste, together with the odor, is then transferred to the inner box 3.
It ascends the opening edge along the side wall, is sucked into the suction groove 4 of the flange duct 6, and enters the hollow part 5, the connecting port 24, and the air passage 22.
Pass through and enter Ozonizer Part 16. Ozonizer-16
In the section, a gas mixture is generated with ozone generated from the ozonizer 16.

Ozone and odors react even in a gas mixture, oxidizing the odor and changing it to something with less odor, but generally the reaction in a gas mixture is 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 17. Moreover, since excess odor is adsorbed by the catalyst 17 and deodorized, no malodorous components remain in the gas exhausted by the exhaust fan 10, base 7, and 18. In addition, the bad odor adsorbed in the catalyst is decomposed by excess ozone at the initial stage of inserting kitchen waste, that is, when there is little bad odor, so the accumulation of bad odor components can be relatively small, resulting in a long service life. can be made to last. Normally, in the case of an ozonizer that generates ozone by applying a high voltage, the amount of ozone generated and the speed of decomposition on the catalyst surface change depending on the humidity. If even a small amount of kitchen waste is put there, the humidity in the storage 1 becomes a relative humidity of 8o to IQO%, so in this embodiment, ozone is generated by the voltage and frequency of the high voltage generator 26 according to the humidity at that time. The generation concentration was set at approximately 1 ppm.

In addition, since the discharge of the ozonizer 16 tends to become unstable in a humid atmosphere, the ozonizer 16 can be heated by applying a voltage that uses an induction electrode (not shown) as a heater in a separate circuit.
16 It is necessary to heat the surface. This prevents dew condensation on the electrode surface and stabilizes ozone production in a humid atmosphere.

In this example, the resistance of the heater is 8Ω, and the resistance is 11A.
−7 A commercial power supply of 1 oov was applied to obtain a surface temperature of 40°C. 'The outside temperature at that time was 20°C.

Next, even if the opening/closing lid 3 is opened, the exhaust fan 18 continues to operate, so the inside of the refrigerator is not depressurized and outside air is introduced through the opening 2, causing most of the bad odor inside the refrigerator. Enter 4.

Therefore, since the inside of the inner box 3 becomes a negative pressure, scattering of bad odor beyond the opening 2 can be avoided as much as possible. In this example, the displacement was approximately 302/min.

In the present invention, a hollow portion 5 is provided inside the flange down 6.
is provided, and the bad odor inhaled from the suction groove 4 is transferred to the air passage 22 on the back side.
However, the same effect can be obtained by using the space between the outer box 9 and the inner box 3 as an air passage. However, if the opening of the air passage is provided around the surface on which the polyethylene bag 11 is attached, there is a risk that the opening of the air passage may be closed off by the ear of the polyethylene bag 11. The suction groove 4 is provided on the dust side of the flange, so even if there is an extra edge of the polyethylene bag 11 in the opening 2 of the inner box 3,
Since the ribs 27 formed on the flange dust 6 are closed while pushing the ears of the polyethylene bag 11, the suction groove 4 is not blocked by the ears of the polyethylene bag 11.

As described above, the present invention includes an inner box for storing kitchen waste, a removable flange duct having a suction groove located on the inner periphery of the opening of the inner box, and an outer box for opening and closing the opening of the inner box. It consists of a lid, an ozonizer that applies high voltage to generate ozone, a catalyst that deodorizes and decomposes ozone, and an exhaust fan.Odors inside the inner box are transferred to the exhaust fan from the intake groove of the flange duct. This device exhausts air outside the warehouse through an ozonizer and catalyst, and as outside air is blown onto the food waste, the concentration of bad odors inside the warehouse is reduced, and a dry film is formed on the surface of the food waste.
In addition to suppressing the generation of bad odors, the ozone decomposition catalyst, which also functions as ozone and deodorization, completely removes the bad odor of the exhaust gas, and even when the outer lid is opened, the bad odor does not exit the refrigerator. It has a deodorizing function with a long deodorizing life.

131. Furthermore, by providing a suction groove on the removable flange duct in the inner box containing the polyethylene bag, the bag has a deodorizing function that is easy to handle and reduces the risk of the ears of the polyethylene bag blocking the exhaust air passage. It provides kitchen waste storage.
