BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing machine for processing kitchen garbage such as garbage used for ordinary households and businesses.

[0002]

2. Description of the Related Art Conventionally, this type of kitchen garbage disposer has a disposer for crushing garbage and flowing it to sewage, and crushing garbage.
There is a garbage dewatering machine that dewaters and collects. Disposers pollute rivers and cause environmental pollution in areas without sewage treatment facilities. On the other hand, the garbage dewatering machine collects dehydrated garbage and does not directly cause environmental pollution. However, the collected garbage easily rots when left untreated, and generates a bad smell. For this purpose, deodorized and collected garbage must be stored at low temperatures or frequently sent to public garbage collection points for disposal.

[0003] As described above, the conventional kitchen garbage processing machine has a problem that it causes environmental pollution and requires much time for processing after processing by the processing machine.

Therefore, the garbage is reduced and its original weight is reduced by pulverizing and drying the garbage. Further, the garbage processing machine does not rot or generate an odor even when left unattended, and does not require any trouble in post-processing. Has been proposed.

[0005]

In the above-mentioned garbage disposal machine of the crushed and dried type, when the garbage stored in the garbage storage container is dried, as the drying proceeds, the garbage sticks to the wall surface of the garbage storage container and can be easily taken out. Disappears. In particular, sugars such as sugar and fruits frequently contained in kitchen garbage, starch such as rice, proteins such as eggs and meat tend to stick.

[0006] Generally, stainless steel is used for such kitchen waste storage containers. However, kitchen waste is extremely liable to stick, and there is a problem that garbage does not fall unless immersed in hot water or soapy water for a long time and rubbed with a scourer. Was. In addition, there is a problem that the garbage storage container rotates during crushing, and it takes time to crush.

[0007] The present invention has been made to solve the above-mentioned conventional problems, and has as its object to make it easier to take out refuse in a storage container and to stir the garbage more efficiently.

[0008]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a garbage storage container for storing garbage, heating means for heating the garbage in the garbage storage container, and a removable garbage storage container. The garbage processing machine main body disposed in the garbage storage container, a rotating blade for stirring the garbage is disposed at the inner bottom of the garbage storage container, and a detent is formed on the garbage processing storage container and the garbage processing machine main body side. It was done.

According to this configuration, the garbage put into the garbage storage container is stirred by the rotating blade rotated by the drive motor and heated by the heating means. Dried garbage remains in the garbage storage container, but is reduced in bulk,
Since it is dried and has a low water activity, it does not rot or emit a bad smell even if it is left in a kitchen waste container. Therefore, the garbage can be put on the dried garbage one after another until the garbage storage container is full, and the garbage can be dried. When the garbage storage container is full of dry garbage, the garbage storage container is removed from the garbage disposal machine body, transported to a garbage disposal place, and discarded. In addition, since the garbage storage container and the garbage disposal machine body are formed with detents,
The garbage storage container can be prevented from rotating, and the garbage can be efficiently stirred.

[0010]

According to this configuration, the garbage put into the garbage storage container is stirred by the rotary blade rotated by the drive motor and heated by the heating means. The garbage is dried by agitation and heating, and the dried garbage remains in the garbage storage container, but is left in the garbage storage container as it is reduced in bulk and dried and has reduced water activity. Even if it does, it does not rot or generate odor.
Therefore, the garbage can be put on the dried garbage one after another until the garbage storage container is full, and the garbage can be dried. And when the kitchen waste container is full of dry garbage,
Take out the garbage storage container from the garbage disposal machine, transport it to the garbage disposal area and throw it away. In addition, kitchen waste storage containers and kitchen waste
Since the detent is formed on the processing machine main body side , the garbage storage container can be prevented from rotating, and the garbage can be efficiently stirred.

According to a second aspect of the present invention, there is provided a garbage storage container for storing garbage, heating means for heating the garbage in the garbage storage container, and a garbage disposal machine in which the garbage storage container is arranged so as to be freely taken out. A main body, a rotating blade and a fixed blade are arranged in the kitchen waste container, and the kitchen waste is configured to be crushed and agitated, and a detent is formed on the kitchen waste container and the kitchen waste processing machine main body side . Things.

According to this configuration, the garbage put into the garbage storage container is stirred and crushed by the rotating blade and the fixed blade rotated by the drive motor, and is heated by the heating means. The garbage is efficiently dried by stirring and heating, and further crushing, and the dried garbage remains in the garbage storage container, but the bulk is reduced, and the garbage is dried and the water activity is reduced. Even if left in the kitchen garbage container, it does not rot or emit odor. Therefore, the garbage can be put on the dried garbage one after another until the garbage storage container is full, and the garbage can be dried.
When the garbage storage container is full of dry garbage, the garbage storage container is removed from the garbage disposal machine body, transported to a garbage disposal place, and discarded. In addition, kitchen waste containers and kitchen waste disposal
The garbage storage container can be prevented from rotating by the detent formed on the machine body side , and the garbage can be efficiently stirred and crushed.

According to a third aspect of the present invention, at least the inner surface of the kitchen waste container is formed of a material having a water contact angle of 70 degrees or more.

According to this configuration, since there is a correlation between the tendency of sticking of the garbage and the contact angle of water, the garbage storage container is made of a material having a contact angle of water of 70 degrees or more, or another material such as metal. By coating, lining or laminating a material having a contact angle of water of 70 ° or more on the surface of the garbage, that is, the portion where the garbage comes into contact, the garbage can be prevented from sticking.

According to a fourth aspect of the present invention, the kitchen waste container is formed of a polyphenylene sulfide resin having a linear polymer structure.

In order to dry the garbage quickly, the drying temperature may be increased. For this purpose, it is necessary to use a material having better heat resistance and durability. In such a case, glass fiber or glass fiber is generally used. Inorganic filler is mixed, but on the contrary, kitchen garbage tends to stick. On the other hand, in order to further improve the usability, it is desirable to use a material that does not crack even if the container is shocked or dropped. This can be realized by using a polyphenylene sulfide resin having a linear polymer structure for a kitchen waste container.

According to a fifth aspect of the present invention, at least the inner surface of the kitchen waste container is formed of a material blended with a fluororesin.

According to this configuration, by blending a fluororesin having an extremely large contact angle with water, it is possible to further improve the difficulty of sticking of the base material and, unlike the inorganic filler, is made of a polymer having flexibility. The impact strength and the drop strength can be improved, and the slidability is further improved, so that the inner surface of the container can be reduced in wear.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The basic configuration of the present invention will be described with reference to FIG.

As shown in the figure, the heat insulating container 1 is a vacuum heat insulating container in which a space formed by an inner wall and an outer wall is evacuated.
However, the heat insulating container 1 may be made of a heat insulating material such as glass wool as long as it has a structure that blocks heat. The garbage storage container 2 is installed so as to be able to be taken out of the heat insulation container 1, and a fixed blade 3 and a rotary blade 4 are provided in the garbage storage container 2 as means for crushing and stirring the garbage. The rotary blade 4 is provided on the inner bottom of the kitchen waste container 2, and is fixed to a rotating shaft 5 protruding from the bottom surface of the kitchen waste container 2. Above the garbage storage container 2, a heater 6 as a garbage heating means and a fan 7 for uniformly sending the heat of the heater 6 into the garbage storage container 2 are provided. 8 is a fan motor.

A condensing section 9 for condensing water vapor generated from kitchen garbage is arranged on the outer peripheral portion of the heat insulating container 1. Further, a blower fan 10 for cooling the outer surface is provided outside the condenser 9. The rotation of the rotary blade 4 is performed by moving the rotary shaft 5 via a drive motor 11, a reduction gear 12 as a reduction gear, a drive shaft 13, and a coupling unit 14. A condensed water outflow pipe 15 and an exhaust pipe 16 are connected to a lower portion of the condensing section 9. A condensed water container 17 is detachably provided at the end of the condensed water outflow pipe 15. The exhaust pipe 16 is provided with a deodorizing device 18. Reference numeral 19 denotes a kitchen waste treatment machine main body containing the heat insulating container 1, reference numeral 20 denotes kitchen waste, and reference numeral 21 denotes a lid containing kitchen waste heating means. The lid 21 can be freely opened and closed on the garbage disposal machine body 19, sandwiches a packing, and has a latch-type handle 22.
, The lid 21 and the garbage disposal machine body 19 are fixed.

The operation of the above configuration will be described. The garbage 20 put in the garbage storage container 2 is stirred and pulverized between the fixed blade 3 and the rotary blade 4. At the same time, it is heated by the heater 6 and diffuses heat evenly in the kitchen waste container 2 by the fan 7. Further, water vapor containing an odor component is generated from the kitchen waste 20, and the heat insulating container 1 is opened through the opening of the kitchen waste storage container 2.
Flows into the condensing section 9 outside the. And the water vapor is condensed 9
In the above, the air is cooled by the blower fan 10 and condensed, and is accumulated in the condensed water container 17 through the condensed water outflow pipe 15.

On the other hand, the water vapor containing the odor component that has not been completely condensed is guided from the exhaust pipe 16 to the deodorizer 18, where the odor component is purified. The crushed and dried garbage remains in the garbage storage container 2, but is reduced in bulk, and has a reduced water activity due to drying. No mold is generated. Therefore, the kitchen waste 20 can be put on the dried kitchen waste one after another until the kitchen waste container 2 is full, and the kitchen waste 20 can be dried. Then, the dried garbage remaining in the kitchen waste container 2 and the condensed water accumulated in the condensed water container 17 are periodically collected and discarded.

Next, described in detail Experiment Example 1 of garbage container 2.

The garbage container 2 of FIG . 1 is prepared by selecting materials relatively resistant to organic acids, amines, vegetable oils, animal oils, and water vapor which are produced in large amounts from the garbage 20 (Table 1). Made with ingredients, kitchen garbage fish, meat, rice, citrus, vegetables, egg shell, soy sauce, sauce, dressing, sugar in weight ratio 10: 10: 10: 30: 30: 30: 2: 2: 2: 2:
2 and set in a garbage disposer having the configuration shown in FIG.
Then, the temperature of the upper layer of the kitchen garbage was controlled to about 110 ° C., and about 85% of the water in the original kitchen garbage was evaporated and dried. Thereafter, the degree of sticking of the garbage to the inner wall of the garbage storage container 2 in a cooled state is shown in (Table 1). In addition, the size of the kitchen waste container 2 is about 200 mm in diameter, about 200 mm in depth, and 2-3 mm in wall thickness. In addition, none of the materials contains glass fiber or inorganic filler. At the same time, the contact angle of water at normal temperature was measured with a test piece of the same material.
The results are shown in (Table 1).

However, PPS: polyphenylene sulfide resin PSF: polysulfone resin PES: polyether sulfone resin TPX: polymethylpentene resin COC: cyclic olefin copolymer PTFE: tetrafluoroethylene resin PFA: ethylene tetrafluoride-perfluoroalkyl vinyl ether Polymerized resin PVDF: vinylidene fluoride resin ETFE: ethylene tetrafluoride-ethylene copolymer resin *) Judgment criteria for sticking A: Almost no sticking. Also, it can be easily removed. ○: Slightly sticky, but relatively easy to remove by hand. △: Slightly sticky, washable with water. ×: Sticky. It cannot be removed unless it is immersed in hot water or immersed in a detergent and washed. As shown in Table 1, nylon and unsaturated polyester heat-resistant resin, stainless steel, stainless steel coated with ceramics, and contact angle of water at room temperature However, those having a temperature of 65 degrees or less are very liable to stick, and cannot be removed without immersion in hot water or immersion in a detergent. In particular, in a device that dries while stirring and pulverizing as in this experimental example, the device easily sticks to the wall surface of the container or jumps and sticks.

On the other hand, PPS having a contact angle of water of 70 degrees or more,
Resins such as PSF, PES, PP, TPX, and COC, fluorine-based resins, and those in which a fluorine-based resin is coated on a stainless steel surface, the kitchen garbage hardly sticks. In addition, even if it sticks, it can be removed by simple washing with water.

[0030] One technique, described experiment example 2 of another garbage container 2.

[0031] In the real Kenrei, although the contact angle of water is 70 degrees or more materials suitable as kitchen waste container 2, PS
F and PES are slightly weak in acid resistance at high temperatures of 100 ° C. or higher, and olefins are weak in heat aging resistance and oil resistance. Therefore, when the drying treatment is performed with a relatively high temperature of one hundred and several tens of degrees Celsius, the above-mentioned materials have a little poor durability. Of course, these materials may be used when durability is not required or when drying is performed at a slightly lower temperature for a long time. Fluororesin moldings have a low heat distortion temperature and are expensive. Further, when the fluorine coating is dried while being stirred and pulverized, it is liable to peel off due to abrasion, so a thick film is necessary, but this is also expensive. In addition, when a metal container is used as a base, the container becomes heavy, which makes it difficult to carry.

[0032] In experiment example 2 above another garbage container 2, no problems as described above, i.e., heat resistance, chemical resistance, body oil, further squeezing excellent PPS resin steam-resistant explains that increasing the practicality.

[0033] The garbage container 2 of Figure 1 made with various materials shown in Table 2, the same garbage as Experiment Example 1 were placed about 1Kg,
It is set in the kitchen waste treatment machine having the configuration shown in FIG. 1, and hot air is sent to the kitchen waste from above by means of the heater 6 and the fan 7, and the temperature of the kitchen upper layer is controlled to about 110 ° C. About 85% was evaporated to dryness. Thereafter, the degree of sticking of the refuse to the inner wall of the kitchen waste storage container 2 in a cooled state is shown in (Table 2). In addition, the size of the kitchen waste container 2 is about 200 mm in diameter, about 200 mm in depth, and 2-3 m in thickness.

Here, in order to confirm the brittleness which is a drawback of PPS, what happens when the kitchen waste container 2 is accidentally dropped is described.
It confirmed that it dropped on concrete from height 50cm and 70cm. The results are shown in (Table 2).

The contact angle of water does not vary greatly depending on the presence or absence of filler and the difference in polymer structure.
It was between 5 degrees, and the eyes with glass fiber were small eyes, and those with fluorine resin were large eyes. As shown in (Table 2), it is clear that those having no filler and having a linear type PPS and a special linear type polymer structure and having high elongation and impact strength are also strong against drop impact. Compared to these,
Semi-linear type and bridge type have low drop strength. In addition, an improvement in drop impact can be seen even in a material containing a fluororesin or a small amount of a fibrous substance. These non-filled containers and containers containing fluororesin can get a little garbage, but can be easily removed with a simple rinse even if they stick. On the other hand, resin containers containing glass fiber inorganic materials, which are commonly used in the past, have excellent drop strength, but tend to stick,
Unless it is soaked in hot water or detergent, it cannot be removed unless it is washed.

In addition, in the case of containing a fluorine resin, the container surface does not wear due to the good slidability in the durability.
It also has the advantage of being resistant to sticking even if damaged.
