Abstract

PROBLEM TO BE SOLVED: To improve deodorizing efficiency and to reduce the generation of a smell peculiar to a garbage disposing mechanism by a method wherein the surface of a heating means is coated with a catalyst to deodorize a smell component of smell gas. SOLUTION: A blast means comprised by a motor 8 and a hot-air fan 9 is attached on an inner wall 7 of a cover 5. Further, a heater 2 is arranged at the lower part of the cover 5 and the surface of a heater 2 is coated with a catalyst 10 to deodorize a smell component from smell gas, such as steam and a smell component generated from a drying chamber 1, through vapor deposition. An oxidation catalyst, such as platinum, platinum-palladium, and nickel, is used as the catalyst 10. Further, when the thickness of the catalyst 10 is increased too much, the catalyst is easy to peel, and approximate 5-10μm is desirable. Since the generation of a smell during disposing is reduced by a catalyst on the surface of the heater, dispersion of a smell at the time of opening of a cover is suppressed.

BEST MODE FOR CARRYING OUT THE INVENTION The kitchen waste processing machine of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a sectional view showing an embodiment of the garbage treating machine of the present invention, FIG. 2 is a sectional view showing another embodiment of the garbage treating machine of the present invention, and FIG. 3 is a drawing of the garbage treating machine of the present invention. It is an important section sectional view showing other examples.

As shown in FIG. 1, the kitchen waste treating machine of this embodiment includes a drying chamber 1 for storing kitchen garbage such as garbage and drying it.
The drying chamber 1 is composed of a blowing means for blowing warm air and a heater 2 which is a heating means for heating the drying chamber 1. The drying chamber 1 is provided in the main body 3 of the processor, and the garbage container 4 containing the garbage is detachably mounted in the drying chamber 1. The upper part of the drying chamber 1 is covered with a dome-shaped lid 5, and the inside of the drying chamber 1 is kept airtight by a packing 1a. The material of the dust container 4 is preferably stainless steel which is hard to corrode or coated with polytetrafluoroethylene so that dust does not stick. Further, a catalyst deodorizer 6 is connected to the exhaust path from the drying chamber 1.

The inner wall 7 of the lid 5 is provided with air blowing means including a motor 8 and a warm air fan 9. Further, the heater 2 is provided below the lid 5, and a catalyst 10 for deodorizing odorous components such as steam and odorous gas such as odorous components generated from the drying chamber 1 is provided on the surface of the heater 2. It is applied by vapor deposition or the like. Catalyst 1
As 0, a platinum-based, platinum-palladium-based, nickel-based, or other oxidation catalyst can be used. Also the catalyst 10
If the film thickness is too thick, the film easily peels off, so that it is preferably about 5 to 10 μm. The reason why the catalyst is used for deodorization is that the treatment can be carried out without increasing the temperature so much, that it is easy to maintain and that the treatment capacity is high.

The catalyst deodorizer 6 may be, for example, a honeycomb catalyst layer 11 and a catalyst heating heater 12 arranged in a case 13. Catalyst layer 1
In No. 1, a honeycomb structure of a platinum-based, platinum-palladium-based, nickel-based or the like oxidation catalyst is used. The heater 12 is a sheathed heater formed in a coil shape.

The drying treatment of the kitchen waste of this embodiment is performed by blowing the air heated to about 110 to 140 ° C. by the heater 2 by the warm air fan 9 so that the warm air is applied to the kitchen waste. The odorous gas generated from the garbage contacts the catalyst 10 while the warm air is circulating in the drying chamber 1, the odorous components are deodorized by the oxidation reaction, and then the gas is exhausted from the exhaust port 14. In this embodiment, since the catalyst deodorizer 6 is connected to the exhaust port 14, the air that has not been sufficiently deodorized during circulation is sufficiently deodorized while passing through the catalyst deodorizer 6 and exhausted to the outside. To be done. Therefore, the deodorizing efficiency can be further improved.

Next, another embodiment of the present invention will be described. As shown in FIG. 2, the kitchen waste processing machine of this embodiment has a drying chamber 21 for storing and drying kitchen garbage such as garbage, and the drying chamber 21.
It is composed of an air blowing means for blowing warm air therein and a catalyst deodorizer 22 for deodorizing odorous components from odorous gas such as water vapor and odorous components generated from the drying chamber 21. As the air blowing means, as in the above-described embodiment, the one including the motor 23 and the warm air fan 24 can be used. The catalyst deodorizer 22 is provided so as to penetrate the lid 25 in the upper part of the drying chamber 21, and the outer peripheral surface of the deodorizer 22 is for deodorizing the odorous components of the odorous gas as in the above-described embodiment. Catalyst 26 is applied. As the catalyst deodorizer 22, a honeycomb catalyst layer 27 and a catalyst heating heater 28 arranged in an L-shaped catalyst case 29 can be used as in the above embodiment. The catalyst case 29 is
It is made of metal such as stainless steel.

In the drying treatment of the kitchen waste of this embodiment, the catalyst case 2 heated to about 250 ° C. by the heater 28 for heating the catalyst is used.
The air heated by 9 is blown by the hot air fan 24 so that the hot air is applied to the kitchen waste. In addition, the odorous gas generated from the kitchen waste comes into contact with the catalyst 26 and is deodorized while the warm air is circulating in the drying chamber 21 as in the above embodiment, and then flows into the suction port 30 and is heated again by the heater 28. After passing through the catalyst layer 27, it is sufficiently deodorized. Then, the gas is exhausted to the outside from the exhaust port 31 through the inside of the lid 25. At this time, the air is mixed with the outside air sucked by a cooling fan (not shown), cooled to a low temperature, and then discharged.
In the present embodiment, the heat generated by the catalyst case (radiant heat) is used and the catalyst is applied to the surface of the catalyst case, so that the odor can be suppressed during processing and at the time of opening the lid. Further, the applied two-stage catalyst of the catalyst 26 and the catalyst deodorizer 22 can improve the efficiency as compared with the conventional deodorization using only the catalyst. Furthermore, even if a small deodorizer is used as the deodorizer 22, a deodorizing effect equal to or more than the conventional one can be obtained, so that the production cost can be reduced.

In the present embodiment, the catalyst 26 is applied to the outer peripheral surface of the catalyst case 29 in the catalyst deodorizer 22, but the present invention is not limited to this and is shown in FIG. 3, for example. As described above, the catalyst 34 can be applied to the inner peripheral surface of the catalyst case 33 in the catalyst deodorizer 32. In this case, the heated air agitated by the hot air fan 35 is introduced from the suction port 36. Then, the introduced air is deodorized by the catalyst 34 and the catalyst layer 38 heated to about 400 ° C. by the heater 37. In this case as well, the deodorizing efficiency can be increased and the size of the deodorizer can be reduced, as in the embodiment shown in FIG.

[0017]

As described above, according to the present invention,
The catalyst on the surface of the heater can reduce the odor during processing, so that the odor at the time of opening the lid can be suppressed.

Further, the heat generated by the catalyst case (radiant heat) is used to apply the catalyst to the outer peripheral surface or the inner peripheral surface of the catalyst case, so that the odor of kitchen waste is deodorized by the catalyst applied during the treatment and the deodorizer. It is possible to improve the deodorizing efficiency.

Further, since the installed catalyst deodorizer can be complemented to allow a sufficient deodorizing capacity, the catalyst layer can be downsized to have the same deodorizing capacity. As a result, the catalyst case can be downsized, the degree of freedom in arranging the catalyst case is increased, and the garbage processing machine can be downsized.
