Description of the Related Art Conventional garbage disposal machines of this type include a bio-type in which kitchen garbage stored in a kitchen garbage container is processed by biotechnology and the like to be composted, and an electric heater for heating and drying the kitchen garbage. There are formulas.

[0003] The above-mentioned bio-type one cannot be installed indoors because the equipment becomes large and emits a lot of bad odors during the treatment, and is used outdoors, but it is installed outdoors. Not available without space. Therefore, there are many restrictions on its use.

[0004] Further, in the electric heater type for heating and drying garbage, the garbage is gradually heated and dried. At this time, water vapor containing odor is generated, and is discharged to the outside through the deodorizing device little by little together with the air in the kitchen waste container using the deodorizing device. This deodorizer removes odor by passing exhaust gas through a heated catalyst. Therefore, steam and air containing odor in the garbage storage container are exhausted by a fixed amount so as not to exceed the processing capacity of the catalyst, and the odor does not hinder use even if the garbage processing machine is installed indoors. It has been removed to a degree.

[0005] Further, the interior of the machine becomes hot because high-temperature air is sent into the garbage storage container. However, the control circuit has many electronic components mounted on the board,

And the air sucked into the cooling fan from the first air passage and the second air passage is discharged to the outside of the main body from the exhaust port of the cooling fan. The fan that discharges air to the outside and the fan that discharges air in the kitchen storage container are integrated, and multiple motors are exhausted with one motor and one fan, reducing noise, weight, and cost. is there.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION According to the present invention, kitchen garbage is charged into a kitchen garbage container, heated air is blown into the kitchen garbage to heat the kitchen garbage, and steam containing odor is generated in the kitchen garbage container. At the same time, a first air passage for guiding a certain amount of exhaust gas little by little to the outside of the main body through the deodorizing device is formed.

[0010] Further, the interior of the main body becomes hot because high-temperature air is sent into the kitchen waste container. However, many electronic components are mounted on the substrate in the control circuit, and some of the electronic components have a regulated use ambient temperature.

[0011] Therefore, since it is also required to maintain the ambient temperature at or below a predetermined temperature, a second air path for guiding heated air inside the main body outside the kitchen storage container to the outside of the main body is formed.

By connecting the first air path and the second air path to the suction port of one exhaust fan, it is possible to exhaust the air from a plurality of systems by using a single fan and motor. , Weight, noise, and cost.

The present invention has the above-described configuration, and its operation will be described next.

When the garbage is put into the garbage container 4 and the drying operation is started, first, the heating means 12 composed of an electric heater is energized, and the electric motor 9 for driving the rotary stirring blade 6 is determined in advance. Forward and reverse rotations are repeated for the specified time.

Thereafter, when a predetermined time elapses, the fan motor 13b for driving the sirocco fan 13a of the blower 13 and the exhaust motor 23 for driving the cooling fan 22 operate, and the inside of the kitchen waste container 4 is Circulate hot air through

The flow of the air blown by the blowing means 13 will be described. The air passing through the circulating air passage 16 c of the circulating air duct 16 is heated by the heating means 12 installed near the blowing port 14 and then heated by the heater 12. It is sprayed on the wall surface of the kitchen waste container 4 through the cover opening 17a.

Further, the garbage is applied to the kitchen garbage along the wall surface of the kitchen garbage container 4, passes through the heater cover opening 17b while drying the kitchen garbage, and flows from the circulation air passage 16e to the air blowing means 1e.
The circulation is performed in such a manner as to return to the sirocco fan 13a which is a component of the third embodiment.

The circulating air is supplied when the rotary stirring blade 6 is appropriately operated while supplying power to the heating means 12 so that the ambient temperature detected by the temperature sensor 28 is maintained at 110 ° C. to 140 ° C. The garbage is agitated and crushed by the fixed blade 5 attached to the inner wall of the garbage storage container 4 to generate steam and drying proceeds.

On the other hand, by the operation of the cooling fan 22, the air that has cooled the components (not shown) incorporated on the substrate in the main body 1 is guided from the second air passage 22 b to the exhaust port 26, and Is discharged.

At the same time, when the cooling fan 22 operates, the pressure in the first air passage 22a becomes lower than the atmospheric pressure, and the odor-containing atmosphere in the kitchen waste container 4 is sucked through the odor outlet 19, After being deodorized by passing through the catalyst deodorizer 20, the air is sucked into the cooling fan 22 through the exhaust pipe 25 and the first air passage 22a, mixed with the cooling air from the exhaust port 26, and discharged to the outside of the main body 1.

By the suction and exhaust, the circulation ventilation duct 1
Since the pressure in the inside 6 is lower than that of the atmosphere, the circulation ventilation duct 1
The outside air is taken into the circulation ventilation duct 16 through the ventilation port 16 d provided in the air circulation duct 6.

In this state, as the drying of the garbage proceeds, the temperature of the outer wall of the garbage container 4 also rises, and when the temperature reaches the temperature at which the drying of the garbage ends, the temperature is reduced to the fixed container 3. Is detected by the container sensor 27, and the power is turned off to terminate the operation.

In the present invention, the surface temperature of the heating means 12 rises to about 650 ° C. while the garbage put in the garbage container 4 is being dried.

Therefore, in the present invention, as described above, the sirocco fan 13a and the fan motor 13b, which are the components thereof, are
And a circulating air duct 16 avoiding above the kitchen waste container 4.
To prevent the blowing means 13 from being heated by the heating means 12.

Further, since the heating means 12 is arranged in the vicinity of the blower opening 14 into which the hot air is blown into the garbage storage container 4 apart from the blower means 13, heat loss is small and the kitchen refuse can be efficiently dried. .

Further, in the conventional product, a fan for discharging the exhaust gas passing through the catalyst deodorizer 20 and a fan for discharging the hot air inside the main body to the outside are separately provided, so that two motors are used or one motor is used. A method of rotating two fans with two motors is used, which increases the cost or requires a large torque to rotate two fans with one motor. There is a problem that the cost is high and the weight is heavy.

However, according to the present invention, the kitchen waste container 4
A first air passage 22a that guides exhaust gas containing water vapor and odor generated inside the main body 1 to the outside, and a second air passage 22b that guides air inside the main body 1 including hot air outside the kitchen waste container 4 to the outside.
And the first air passage 22a and the second air passage 22b are connected to the suction port 24 of the cooling fan 22, so that the conventional problem can be solved only by using one motor 9 and one cooling fan 22. You can do it.

In the present embodiment, the heating means 12 has been described as an example of an electric heater, but it is needless to say that the same effect can be obtained even by electromagnetic induction heating.

[0052]

As described above, according to the present invention, the first air passage for guiding the exhaust gas containing water vapor and odor generated in the kitchen waste container to the outside of the main body, and the main body containing the hot air outside the kitchen waste container. A second air passage for guiding the air inside to the outside is provided, and the first air passage and the second air passage are connected to the suction port of the cooling fan. This can solve the problems such as higher cost and heavier weight than those provided with separate fans for discharging the hot air inside the main body to the outside.

In addition, this makes it possible to reduce the size of the kitchen waste disposal machine.
