Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a garbage processing machine. More specifically, a garbage disposer capable of preventing the temperature of the inside of the deodorizer from being partially lowered due to the wind sent from the blowing means directly hitting one side of the deodorizer, thereby preventing the catalyst deodorization efficiency from being lowered. About.

2. Description of the Related Art Conventionally, as a garbage processing machine for drying garbage, a drying chamber for storing and drying garbage, a heating means for heating the drying chamber, and a cooling section for condensing steam discharged from the drying chamber. And a deodorizer for deodorizing odor components of odor gas. In such a kitchen waste treatment machine, the kitchen waste is heated and dried by the drying heater as the heating means, and the generated odor gas is passed through the catalyst heating heater and the catalyst of the deodorizer. And then mixed with low-temperature ambient air by a cooling fan to reduce the temperature before discharging to the outside of the main body. However, the kitchen waste treatment machine has a drawback that the number of parts is large and the production cost is high because the heater for drying and the heater for heating the catalyst are used separately.

[0003] The applicant of the present invention has previously proposed a garbage disposal machine in which the number of parts is greatly reduced by using a common heater (Japanese Patent Application No. 8-131578). This kitchen waste treatment machine includes a drying room for storing and drying kitchen waste, a blowing means for blowing hot air into the drying room, and a deodorizer for deodorizing odor components of odor gas, and covers the drying room. The deodorizer is provided below the lid, and a heating source of the hot air is a heating unit of the deodorizer (for example, a catalyst heater).

[0004] In such a kitchen waste treatment machine, a part of the wind generated by the blowing means hits a deodorizer provided at the lower portion of the lid and receives a part of the heat of the heating part of the deodorizer, thereby generating hot air. Dry the garbage inside the drying room using warm air.

[0005]

However, in the above-mentioned conventional garbage disposer, the wind sent from the blowing means directly hits one side of the deodorizer (the side facing the blowing means).
The temperature of the catalyst inside the deodorizer may partially decrease. As a result, the odor gas passing through the portion where the temperature inside the deodorizer is lowered is exhausted to the outside without being sufficiently decomposed and deodorized, so that there is a problem that the odor is released to the outside.

[0006] Further, the residual odor released to the outside when the lid is opened after processing the garbage is unpleasant because it has a strong burnt odor together with the odor inherent in the garbage. Conventionally, there are products that use ozone deodorization to reduce the odor in order to deodorize the unpleasant residual odor. However, the deodorizing effect of ozone is generally low. On the other hand, if a product having a high ozone concentration is used, there is a problem that the irritating odor of ozone itself becomes strong.

The present invention has been made in order to solve such a problem, and the air blown from the blowing means directly hits one side of the deodorizer, whereby the temperature inside the deodorizer is partially lowered, thereby causing the catalyst to be degraded. It is an object of the present invention to provide a garbage disposer capable of preventing the deodorizing efficiency of the garbage from decreasing. Further, another object of the present invention is to provide a kitchen garbage disposer capable of alleviating a residual odor when the lid is opened.

[0008]

According to the present invention, there is provided a garbage processing machine,
A drying chamber for storing and drying the garbage; blowing means for blowing hot air into the drying chamber; and a deodorizer having a catalyst and a heater for deodorizing odor components of odor gas, the heating source for the hot air. Is a garbage disposer that is a heater of the deodorizer, and at least a portion around the deodorizer,
The apparatus is characterized in that an air distribution means for dispersing the air sent from the air blowing means is provided.

It is preferable that the air distribution means is made of a metal mesh or a metal sheet having a plurality of holes.

[0010] It is preferable that an oxidation catalyst is applied to the surface of the metal net or the metal sheet having a plurality of holes.

Further, it is preferable that the air blowing and dispersing means comprises a case having air permeability, and a deodorant housed in the case.

According to the garbage disposer of the present invention, since at least a part of the periphery of the deodorizer is provided with the air distribution means, a part of the wind generated by the air blowing means is blown on the way to the deodorizer. Dispersed by dispersing means. Therefore, it is possible to prevent the temperature inside the deodorizer from being partially lowered due to the wind directly hitting one side of the deodorizer, thereby preventing the deodorization efficiency of the catalyst from being lowered.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a kitchen waste disposal machine according to the present invention. 1 is an explanatory cross-sectional view showing one embodiment of the garbage processing machine of the present invention, FIG. 2 is an enlarged cross-sectional view of a main part of the catalytic deodorizer of FIG. 1, and FIG. FIG. 4 is a perspective explanatory view showing a state where the case of the catalyst deodorizer of FIG. 1 is opened, FIG. 5 is a perspective explanatory view showing a state where the case of the catalyst deodorizer of FIG. 1 is closed, and FIG. It is a principal part expansion perspective view of the catalyst deodorizer and the case containing a deodorant which show another Example of the kitchen waste processing machine of this invention.

The kitchen waste treatment machine shown in FIG. 1 includes a drying chamber 1 for storing and drying kitchen garbage such as garbage, a blowing mechanism 13 for blowing hot air into the drying chamber 1, and a drying chamber 1. Catalytic deodorizer for deodorizing generated steam and odor components 2
And a wire mesh 17 (see FIG. 3) for dispersing the wind sent from the blower mechanism 13 to the catalyst deodorizer 2. The drying chamber 1 is provided in the processing machine main body 3, and a processing container 4 containing kitchen waste is detachably mounted in the drying chamber 1. The upper part of the drying chamber 1 is covered with a lid 5, and the interior of the drying chamber 1 can be kept airtight by a packing 1a. The material of the processing container 4 is preferably stainless steel which is hard to corrode or a material coated with polytetrafluoroethylene so that dust is not adhered.

As the catalyst deodorizer 2, a catalyst deodorizer 2 in which a honeycomb-shaped catalyst layer 6 and a catalyst heater 7 serving as a heating unit are linearly arranged in a case 8 having good thermal conductivity and corrosion resistance, such as stainless steel, is used. . In the embodiment shown in FIG. 1, the catalyst layer 6 and the heater 7 for heating the catalyst are disposed in the direction perpendicular to the plane of the drawing.
Is installed at the lower part of the lid 5, and the lower part of the case 8 is exposed to the drying chamber 1. As shown in FIG. 2, a suction port 8 a is formed at an end of the case 8 on the upstream side with respect to the heater 7, while a discharge pipe 10 is provided in the downstream space 9 of the catalyst layer 6 from above. It is connected. The downstream end 10 a of the discharge pipe 10 projects outside the case 8. The catalyst layer 6 has a honeycomb structure made of an oxidation catalyst such as platinum, platinum-palladium, and nickel. 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. As the heater 7, a sheathed heater formed in a coil shape is used.

The case 8 is, as shown in FIGS.
While the exhaust pipe 10 and the pipe 21 around the heater 7 are arranged at predetermined positions, the half cases 18 and 19 are overlapped with each other, and then the caulking portion 20 provided at the peripheral end of one half case 18 is removed. The other half case 19 is manufactured by caulking so as to tighten the peripheral edge thereof. Therefore, the thickness can be reduced as compared with the case where the case is welded, so that the size and the weight can be reduced, and the manufacturing cost is reduced.

At both ends of the heater 7 sandwiched between the cases 8, pipes 21 made of a metal having low thermal conductivity such as SUS or ceramics are press-fitted. For this reason, as described above, when the heater 7 is sandwiched by the case 8 and swaged, the surface treatment of the heater 7 is damaged or the heater wire inside the heater 7 is broken by the pipe 21 acting as a buffer material. No problems occur.

Furthermore, the sealing action of the pipe 21 prevents the odor gas from leaking out of the case 8 between the heater 7 and the case 8.

As shown in FIGS. 1 and 3, the wire mesh 17 is made of SUS having a mesh size of about 1 to 5 mm on a side.
And a net made of metal having excellent heat resistance and corrosion resistance. The net covers the lower half of the case 8 of the catalytic deodorizer 2 and is disposed at an appropriate distance from the case 8.

The surface of the wire mesh 17 is coated with a platinum-based oxidation catalyst for reducing the residual odor when the lid is opened.

The blower mechanism 13 may be composed of a motor 14, a hot air fan 15, and a cooling fan 16 attached to the lid 5. The cooling fan 1
6 is for cooling the motor 14 by air and for the catalyst deodorizer 2
This has two functions of forcibly exhausting the deodorized gas exhausted from the discharge pipe 10 to the outside of the processing machine.

The kitchen waste treatment machine shown in FIG.
a, a stirring motor 12b for rotating and driving the stirring blade 12a, and the stirring blade 12a and the stirring motor 12
and a stirring mechanism 12 composed of a deceleration mechanism section 12c for transmitting and decelerating power between the processing vessel b and a fixed blade 12d fixed to the inner surface of the processing container 4. This stirring mechanism 12 promotes the drying of the garbage by stirring the garbage with the stirring blade 12a and drying the garbage between the stirring blade 12a and the fixed blade 12d when the garbage is dried. Reduce the size of the processed garbage.

In the heating and drying of the garbage in this embodiment, the air blown by the hot air fan 15 comes into contact with the case 8 heated by the heater 7 to perform heat exchange, and then to become hot air and hit the garbage. It is done. At the same time, the odor gas generated during heating and drying is
After heating to about 500 ° C., it is deodorized by passing through the catalyst layer 6, and the deodorized gas is removed by the cooling fan 16.
The temperature is lowered by mixing with ambient air, and the air is forcibly exhausted to the outside of the processing machine.

Since the lower half of the case 8 of the catalytic deodorizer 2 is covered by the wire mesh 17, the wind (air) blown by the hot air fan 15 reaches the case 8 after being dispersed by the wire mesh 17. I do. Therefore, it is difficult for the wind to directly hit the side of the case 8 facing the hot air fan 15. Therefore, the catalyst layer 6 inside the case 8 has a stable temperature distribution as a whole, and the deodorizing efficiency can be stably maintained.

In addition, the wire mesh 17 coated with the oxidation catalyst
Since it becomes high temperature at the end of drying, it can exhibit a deodorizing effect. Thereby, the residual odor at the time of opening the lid can be reduced.

In the present embodiment, a wire mesh has been described as an example of the air distribution means. However, the present invention is not limited to this, and any shape may be used as long as it can exert the air distribution function. And the structure can also be adopted. For example, even if a metal sheet having a plurality of through holes is used in place of a wire mesh, the air blowing and dispersing action can be achieved. Also, if a platinum-based oxidation catalyst is applied to the surface of the metal sheet, the same effect as described above can be obtained. By the action, the residual odor at the time of opening the lid can be reduced.

As another embodiment of the present invention, an air distribution means shown in FIG. 6 may be employed. FIG. 6 shows an air distribution unit 23 composed of a case 22 having air permeability and a deodorant (not shown) stored in the case 22. The other configuration is assumed to be common to the kitchen waste disposal machine of FIG.

The case 22 is made of a gas permeable material such as a wire mesh or a metal sheet having a plurality of holes, and is made to have a hollow body covering the lower half of the case 8 of the catalytic deodorizer 2. The mesh of the wire mesh (or the diameter of the hole of the metal sheet) constituting the case 22 is set so that the deodorant does not spill.

Activated carbon or molecular sieves can be used as the deodorant.

With this configuration, the air from the hot-air fan 15 (see FIG. 1) is unlikely to directly hit the case 8 of the catalytic deodorizer 2 by the air-dispersing section 23 as in the above-described embodiment. The overall temperature distribution becomes stable,
Deodorization efficiency can also be stably maintained.

During the drying process, the temperature of the case 22 and the inside thereof become 100 ° C. or more, so that the odor gas and the water vapor generated from the garbage are hardly adsorbed. However, at the time of cooling, the temperature becomes 100 ° C. or less, and at the time of opening the lid, it becomes 40 to 70 ° C., and the deodorizing agent has a better deodorizing ability than at a high temperature, and the residual odor is reduced as compared with the conventional case. Furthermore, at the time of the next garbage disposal, the temperature of the deodorant rises again, and the adsorbed odor components and the like are eliminated, so that the deodorant is regenerated.

In short, the residual odor generated during the period from the drying process to the time of opening the lid is temporarily absorbed in the deodorant, so that the residual odor at the time of opening the lid can be reduced.

As described above, two examples of the blast dispersing means have been described as the embodiments of the present invention. In each case, the blast dispersing means (the wire mesh 17 and the blast dispersing unit 23) covers the lower half of the catalyst deodorizer 2. An example is shown. However, the present invention is not limited to this, and a grid-like thing, a grill in which bars are arranged in parallel, etc. can be appropriately adopted as long as the wind hitting the catalyst deodorizer 2 can be dispersed. Alternatively, the position of the air distribution unit and the range of expansion may be appropriately changed.

[0034]

According to the garbage disposer of the present invention, it is possible to prevent the temperature inside the deodorizer from being partially lowered by the air sent from the blowing means directly hitting one side of the deodorizer. Therefore, the catalyst has a stable temperature distribution as a whole, and the deodorizing efficiency can be stably maintained.
As a result, there is no problem that the odor is released to the outside.

If an oxidation catalyst is applied to the surface of the air distribution means such as a wire mesh, or if a case containing a deodorant is employed, the residual odor at the time of opening the lid can be reduced.
