In this method, a stirring blade is provided in a processing tank, and the garbage introduced into the processing tank is stirred by rotating the stirring blade, and decomposed by aerobic bacteria. By using these garbage disposal devices, not only the amount of garbage can be reduced, but also the decomposed garbage can be reused as fertilizer, so these garbage disposal devices gradually spread to ordinary households. Have been doing.

[0003] In these garbage disposal apparatuses, bacteria that decompose garbage are sensitive to the growth environment such as the amount of oxygen and temperature changes. It was necessary to always provide optimal growth conditions, such as avoiding an oxygen-rich state. Also,
Since the odorous substances are generated in the process of the bacteria decomposing the garbage, in order to remove these odorous substances, it is necessary to take countermeasures against the odors by providing a deodorizing catalyst and an adsorbent.
And in this case, it is necessary to continuously deodorize,
Generally, a deodorizing catalyst which can be used semi-permanently by heating is used.

However, these garbage disposal devices are
Since air outside the apparatus main body is introduced into the processing tank and the air inside the processing tank is heated and deodorized and discharged outside the apparatus main body, relatively low-temperature outside air is always supplied into the processing tank. As a result, there is a possibility that the power consumed by the heater to increase the temperature in the tank is increased.

Further, when the lid is opened by throwing in garbage or the like, the outside air flows into the processing tank, and the temperature in the tank drops rapidly, thereby suppressing the activity of bacteria and increasing the power consumption of the heater. In addition, there is a possibility that malodorous substances generated by decomposition of the garbage may be leaked.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and to provide a garbage disposal apparatus which keeps the inside of a treatment tank at a high temperature with relatively small electric power, and which does not lower the temperature even when the lid is opened and which does not easily leak odor substances.

Further, the guide portion 27 is integrally formed with a protrusion 27A for guiding the warm air blown from the air supply port 14 to the lower side of the housing portion 3.

A processing tank 28 is detachably accommodated in the accommodating section 3. The processing tank 28 is formed in a cylindrical shape with a bottom, and a handle 30 is pivotally attached to an upper opening 29. A cylindrical receiving portion 31 is formed in the center of the bottom of the processing tank 28 in the vertical direction, and a shaft hole 32 is formed in the center of the cylindrical receiving portion 31. A rotating shaft 33 is vertically and rotatably attached to the shaft hole 32.

And a driven-side rotary joint 34 that engages with the motor. A mounting portion 35 is formed above the rotating shaft 33, and a stirring blade 36 is detachably mounted on the mounting portion 35.

Reference numeral 37 denotes a mounting member for the stirring blade 36. The mounting member 37 includes a hollow cylindrical portion 37A fitted with the mounting portion 35, and an inverted bowl shape from the lower portion of the cylindrical portion 37A. It is composed of a curved portion 37B that protrudes and accommodates the cylindrical receiving portion 31 of the processing tank 28, and a flange-shaped grip portion 37C that protrudes outward from the upper end of the cylindrical portion 37A. Further, a pair of radially projecting blades 38 is fixed to the lower portion of the curved portion 37B, and a spiral portion 39 extending obliquely upward from the pair of blades 38 is integrally formed. The drive transmission unit 8 including the drive-side rotary joint 9 and the driven-side rotary joint 34, the rotation shaft 33, and the stirring blade 36 constitute a stirring mechanism 40. Reference numeral 41 denotes a carrier in which aerobic bacteria are carried on fine wood chips or the like.

Next, the operation will be described. First, the processing tank 28 is inserted into the storage section 3 of the apparatus main body 1, so that the drive-side rotary joint 9 and the driven-side rotary joint 34 are engaged, and
Attach the attachment member 37 of the stirring blade 36 to the attachment portion 35 of. Then, an appropriate amount of the carrier 41 is accommodated in the processing tank 28, and the heater 12 is energized, and the air supply fan 14, the intake fan 16 and the exhaust fan 22 are driven to energize the heating unit 18. At this time, the heat generated by the heater 12 is absorbed by the heat storage material 11 in the heat storage unit 10, and the heat storage material 11 convects to heat the entire heat storage material 11 in the heat storage unit 10 appropriately. The air in the processing tank 28 is also circulated from the intake fan 16 to the air supply fan 14.
The heating unit 18 in 17 is appropriately heated. As a result,
The temperature in the treatment tank 28 rises appropriately, and an environment in which the bacteria carried on the carrier 41 can be actively activated is provided. A part of the air passing through the circulation path 17 is sucked by the exhaust fan 22 and diverted to the exhaust path 20, and is discharged from the exhaust port 21 to the outside of the apparatus main body 1. External air corresponding to the amount is introduced into the circulation path 17 from the introduction hole 24 and sent into the processing tank 28 from the air supply port 14 by the air supply fan 13. The air sent into the processing tank 28 is guided by a guide section.
The carrier 41 is sprayed on the carrier 41 by the
Oxygen is supplied to the inner carrier 41, and the activity of bacteria becomes active. In this state, when the garbage is put into the treatment tank 28 and the electric motor 4 is driven to rotate the stirring blade 36, the garbage and the carrier 41 are stirred and mixed, and the bacteria carried on the carrier 41 are turned into garbage. It adheres and decomposes garbage, generating carbon dioxide, water (steam) and a small amount of malodorous substances. Incidentally, these bacteria are aerobic, when mixing the garbage and the carrier 41 by rotating the stirring blades 36,
When the air in the processing tank 28 is mixed, it is actively activated to decompose garbage. The air mixed with carbon dioxide, water, and malodorous substances generated by the bacteria decomposing the garbage is sucked from the intake port 16 by the intake fan 15, passes through the circulation path 17, and is supplied by the air supply fan 13. Circulation returning from the air supply port 14 to the inside of the processing tank 28 is performed. At this time, the offensive odor substance is removed by the deodorizing catalyst section 19 while circulating through the circulation path 17 and is also removed by the deodorizing catalyst section 23 when being discharged from the exhaust port 21 to the outside of the apparatus main body 1. Then, when the operation is performed for a predetermined time, the inputted garbage is decomposed and disappears, leaving a small amount of debris made of inorganic substances or the like. In addition, carrier
The contents consisting of 41 and garbage debris can be reused as fertilizer.

When fresh garbage is to be introduced after treating the garbage in this way, it is necessary to open the lid 26.
When the lid 26 is opened, the airflow from the intake port 14 guided downward by the guide portion 27 when the lid is closed flows directly to the intake port 16 at the opposing position, thereby forming an air curtain.
This air curtain prevents the low-temperature outside air from flowing into the processing layer 28, and also prevents the high-temperature air containing the malodorous substance in the processing tank 28 from leaking out of the tank.
For this reason, not only can the temperature inside the processing tank 28 be prevented from lowering, but even if the lid 26 is opened, there is almost no smell. In addition, not only the air sent from the air inlet 14 but also some outside air is sucked from the air inlet 16, and the air temperature at the air inlet 16 is lower than the air temperature at the air inlet 14. However, the air is heated by the heating unit 18 and has a high temperature when it is blown out from the air supply port 14. Therefore, immediately after the lid 26 is closed after the garbage is charged, the air in the tank does not decrease and remains at a high temperature.

Further, since the heat storage material 11 heated by the heater 12 is provided in the heat storage unit 10, the carrier 41 is continuously heated by the heat storage material 11 even when the lid is closed, so that the tank at the time of opening the lid is opened. The temperature inside is prevented more reliably. Then, when the contents composed of the aged carrier 41 and the garbage debris in the treatment tank 28 are discharged and a new carrier 41 is charged, the treatment tank 28 is accommodated, especially when all the contents are replaced. It will be taken out of the storage unit 3
Since the inside is continuously heated by the heat storage material 11, the temperature of the carrier 41 returns to the high temperature in a short time even if the processing tank 28 in which the carrier 41 is newly added is inserted into the housing portion 3. Further, since the heat storage material 11 has a large heat capacity, the temperature does not change abruptly even when the heater 12 is controlled, and the temperature environment of the carrier 41 in the processing tank 28 becomes stable.

As described above, the present invention relates to the apparatus main body 1 and the air supply port 14 communicating with the space in the processing tank 28 provided in the apparatus main body 1 and sending air into the processing tank 28. An intake port 16 for sucking air in the tank 28 is formed, a heating unit 18 and a deodorizing catalyst unit 19 are provided in the apparatus main body 1, and air is supplied from the intake port 16 through the heating unit 18 and the deodorizing catalyst unit 19. Circuit leading to mouth 14
17 so that the air in the processing tank 28
From 16, the air is sent to the heating unit 18 and heated, the heated air is deodorized by the deodorizing catalyst unit 19, and the heated and deodorized air returns to the inside of the processing tank 28 from the air supply port 14 again. The inside of the processing tank 28 is heated to a high temperature by the circulating air. For this reason, the inside of the processing tank 28 can be heated by using the heat for heating the catalyst which has been conventionally discharged, and the bacteria can favorably activate the temperature in the processing tank 28 without consuming unnecessary power. Can be kept at a high temperature.

An air supply fan 13 is provided at the air supply port 14,
In addition to providing an intake fan 15 at the intake port 16, the air supply port 14 and the intake port 16 are formed at positions facing each other, and the air supply fan 15 is opened when the lid 26 covering at least the upper part of the processing tank 28 is opened. Since the fan 13 and the intake fan 15 are configured to operate, the air supply port is opened when the lid 26 is opened.
An air curtain is formed by the air current flowing from 14 to the intake port 16, and the air in the processing tank 28 is blocked by this air flow,
Since it does not leak out of the treatment tank 28, the inside of the treatment tank 28 can be kept at a high temperature, and at the same time, the odorous substance can be prevented from leaking out of the treatment tank 28.

Further, a guide portion 27 for guiding the airflow from the air supply fan 13 downward at least opposite to the air supply port 16 is provided below the lid 26, so that the lid 26 is closed. Sometimes, after being heated through the heating unit 18, the air to which the outside air is added from the introduction hole 24 is sent from the air supply port 14,
Because it descends toward the lower side of the processing tank 28 along 27,
The air heated by the heating unit 18 heats the inside of the processing tank 28 and supplies oxygen to the carrier 41, so that the inside of the processing tank 28 can be kept in a state where bacteria can be satisfactorily activated.

Further, a heat storage section 10 having a double structure is provided on the side wall and the bottom of the storage section 3, and a heat storage material 11 such as water is sealed in the heat storage section 10. Since the heater 12 is attached, the heat generated by the heater 12 is absorbed by the heat storage material 11 in the heat storage unit 10, and the heat storage material 11 convects, and the entire heat storage material 11 in the heat storage unit 10 is appropriately heated. Heated. Thereby, the processing tank 28 housed in the storage unit can be effectively heated, and the temperature in the processing tank 28 can be maintained at a high temperature at which bacteria can be satisfactorily activated.

It should be noted that the present invention is not limited to the above embodiment, and various modifications can be made within the gist of the present invention. For example, in the above embodiment, the processing tank is configured to be inserted into the storage portion formed in the apparatus main body, but a structure in which the processing tank is exposed may be used if the processing tank can be kept warm. Further, in the above-described embodiment, an example is shown in which the heat storage unit having the double structure is provided on the side wall and the bottom of the storage unit. However, the heat storage unit may be formed only on one of the side wall and the bottom of the storage unit. Further, water has been described as an example of the heat storage material sealed in the heat storage unit, but the heat storage material is not limited to water, and may be appropriately selected. Further, in the above-described embodiment, an example is shown in which the heat storage unit having the double structure is provided on the side wall and the bottom of the storage unit, but the heat storage unit may be formed on the side wall and the bottom of the processing tank.
