BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste processing device built in a kitchen stand such as a kitchen unit, and more specifically, to a kitchen waste main body of a kitchen stand through a duct from an inlet provided on the kitchen stand surface. The present invention relates to a structure for preventing odors from drifting in the kitchen by a food waste processing device that can put food waste into the kitchen.

[0002]

2. Description of the Related Art In recent years, it has been carried out to decompose (ferment) food waste containing organic substances and water to the extent that it does not affect the environment by utilizing the power of microorganisms. There is known a food waste processing device. This food waste treatment equipment is filled with wood chips called biochips as food waste treatment material in the food waste treatment tank, and the raw garbage is processed from the input port provided in the food waste treatment tank. It is put inside and fermented by the action of microorganisms living in the garbage processing material to decompose it.

FIG. 1 shows an example of a food waste processing device built in a kitchen stand such as a kitchen unit. Inside the kitchen stand 1 like a kitchen unit
Inside the food waste processing tank 3 of the food waste processing apparatus main body 2, a stirring blade 4 is provided. The raw garbage treating tank 3 is filled with the raw garbage treating material 5 so that the garbage is decomposed by the action of microorganisms such as bacteria living in the raw garbage treating material 5. The kitchen stand surface 6 which is the upper surface of the kitchen stand 1 is provided with a charging port 7, and the charging port 7 is provided with a lid 8 which can be freely opened and closed. The charging port 7 and the inside of the garbage processing tank 3 are connected to a duct 9. Have communicated with each other. An outdoor exhaust port 11 is provided outside the outdoor wall 10 of the building, and the outdoor exhaust port 11 and the garbage processing tank 3 are communicated with each other through an exhaust route 12. The blower fan 13 and the catalyst heating type deodorizer 14 are disposed. In FIG. 1, reference numeral 15 is a sink, and 16 is an overflow container for receiving an excess raw garbage processing material overflowing from the garbage processing tank 3.

In such a food waste processing apparatus, food waste generated in the kitchen is put into the food waste treatment tank 3 through the input port 7,
The garbage is decomposed by the action of microorganisms that inhabit the garbage processing material 5. In addition, garbage processing tank 3
Fresh air is sucked into the air and the air in the garbage processing tank 3 is exhausted to the outside. The exhaust gas in the garbage processing tank 3 is exhausted to the outside from the outdoor exhaust port 11 via the exhaust path 12 by driving the blower fan 13. Garbage disposal tank 3
Of the exhaust gas contains an odor generated along with the decomposition of organic substances inside the food waste treatment tank 3, and if the exhaust gas is exhausted as it is, the odor may drift to the surroundings and cause deterioration of the surrounding environment. . Therefore, conventionally, a deodorizer 14 is arranged in the middle of the exhaust path 12, and after deodorizing with the deodorizer 14, the exhaust is discharged outdoors.

[0005]

In the above-mentioned conventional example, the odor generated in the garbage processing tank 3 is deodorized by the deodorizer 14 and exhausted, but the lid 8 is opened to remove the garbage from the charging port 7. At the time of charging, odor may flow back into the kitchen through the duct 9 and the charging port 7. Therefore, in order to prevent odor from flowing back into the kitchen, when the inlet 7 is opened, the air volume of the blower fan 13 is increased, and the amount of air taken in from the inlet 7 is increased to increase the flow velocity and cause odor backflow. I try not to. As described above, by increasing the air volume of the blower fan 13 when the charging port 7 is opened, the odor in the food waste treatment tank 3 does not flow back into the kitchen, so the environment in the kitchen does not deteriorate, but the catalyst heating is required to increase the air volume. The temperature of the deodorizer 14 of the system decreases, the capacity of the deodorizer 14 decreases, and the exhaust path 12
There is a possibility that the odor emitted through the air conditioner may deteriorate the surrounding environment. Further, even if the charging port 7 is closed again, it takes time for the temperature of the deodorizer 14 to rise to a predetermined temperature, and during that period, the odor discharged to the outside may cause deterioration in the surrounding environment.

The present invention has been made in view of the above-mentioned points, and it is possible to prevent the odor from flowing back into the kitchen when the garbage is thrown in by opening the charging port, and to surely deodorize with the deodorizer. An object of the present invention is to provide a food waste processing device that can exhaust air.

[0007]

In order to solve the above-mentioned problems, in the food waste processing apparatus of the present invention, a food waste processing apparatus main body 2 for decomposing food waste with microorganisms is installed in a kitchen stand 1, and a kitchen stand surface 6 is provided. The garbage input port 7 provided in the above and the inside of the garbage processing tank 3 of the above-mentioned garbage processing device body 2 are communicated with each other by the duct 9.
It is a food waste processing device in which a deodorizer 14 for heating and deodorizing and a blower fan 13 are arranged in an exhaust path 12 for exhausting the exhaust gas in the food waste processing device main body 2 to the outside. In order to prevent the odor in the processing device body 2 from flowing back into the kitchen, the exhaust air volume by the blower fan 13 is increased at the same time as the opening 7 is opened, and after a certain period of time, the normal air volume or an exhaust air volume slightly increased from the normal air volume is obtained. The blower fan 13 is controlled so that In this way, by opening the inlet 7 and simultaneously increasing the exhaust air volume by the blower fan 13 and controlling the blower fan 13 so that the regular air volume or the exhaust air volume slightly higher than the regular air volume after a certain time is controlled, the inlet 7 The odor of the food waste that rises to the charging port 7 when the charging port is opened can be suppressed by air, and it is possible to prevent the odor from flowing back into the kitchen when the charging port is opened. Here, the amount of airflow is initially increased to prevent the odor of food waste remaining in the duct 9 from flowing back into the kitchen, and even after a certain period of time, the odor is prevented from flowing back into the kitchen. It is possible. At this time, unlike the conventional case, since the air volume is not continuously increased, the temperature of the deodorizer is less likely to decrease due to the increase in the air volume. Therefore, it is possible to exhaust the air without being restricted by the installation place by surely deodorizing and preventing the deterioration due to the outdoor odor.

It is also preferable that the deodorizing ability of the deodorizer 14 is controlled so as to be changed according to the exhaust air volume. By controlling in this way, it is not necessary to design the deodorizer 14 with an excessive capacity, and the cost (deodorizer initial cost, electricity charge) can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The structure of a food waste processing device is as shown in FIG. 1, and since it is the same as that described in the description of the prior art, duplicate description will be omitted and control will be mainly described.

In the present invention, the blower fan 13 provided in the exhaust path 12 is controlled as follows. That is, in order to prevent the odor in the food waste processing device main body 2 from flowing back into the kitchen when the input port 7 is opened for inputting food waste, the exhaust air volume by the blower fan 13 is opened at the same time when the input port 7 is opened. And the blower fan 13 is controlled so that the normal air flow rate or the exhaust air flow rate slightly higher than the normal air flow rate is reached after a certain period of time.

When this is illustrated, the flow is as shown in FIG. At the same time when the inlet 7 is opened, the exhaust air volume of the blower fan 13 is controlled to be increased. At this time, the rotation speed of the blower fan 13 is increased to increase the air volume so as to be, for example, about four times the normal air volume. As a result, the odor of food waste that rises to the charging port 7 when the charging port 7 is opened can be suppressed by air, and it is possible to prevent the odor from flowing back into the kitchen when the charging port is opened. Then, the opening 7 is opened to increase the exhaust air volume, and the exhaust air volume of the blower fan 13 is decreased when a predetermined time has passed. At this time, the rotation speed of the blower fan 13 is reduced to a normal air volume or an exhaust air volume slightly higher than the normal air volume (for example, about twice the normal air volume). As described above, the increase of the exhaust air volume in the initial stage is to prevent the odor of the garbage left in the duct 9 from flowing back into the kitchen. Even if the air volume is reduced after a certain period of time, the air will flow back into the kitchen. Can be prevented. By lowering the air volume after a certain period of time in this manner, the exhaust air volume does not continue to rise as in the conventional case, so there is less risk of the temperature of the deodorizer 14 decreasing due to an increase in air volume
Decrease in deodorizing ability is small, and there is no danger of odors being discharged and deteriorating the surrounding environment. Then, when the input of the garbage is completed and the input port 7 is closed, the blower fan 13 is controlled so as to have a normal exhaust air volume, and the normal operation is performed.

Further, the exhaust air volume of the blower fan 13 is controlled when the inlet 7 is opened as described above, but at this time, it is also preferable to control so as to change the deodorizing ability of the deodorizer 14 in accordance with the exhaust air volume. This is illustrated in the flow of FIG. At the same time when the charging port 7 is opened, the exhaust air volume of the blower fan 13 is controlled to increase. At this time, the deodorizing ability of the deodorizer 14 is increased according to the exhaust air volume. At this time, the deodorizer 14 is controlled to increase the heat generation amount of the heater for heating the catalyst because of the catalyst heating method. By increasing the capacity of the deodorizer 14 in this manner, even if the exhaust air volume is increased, the deodorizing capacity is not lowered and the predetermined deodorizing capacity is maintained and the deodorizing can be reliably performed. Then, the exhaust air amount of the blower fan 13 is decreased after a certain time has elapsed after opening the inlet 7 and increasing the exhaust air amount, but at this time, the deodorizing ability of the deodorizer 14 is decreased according to the exhaust air amount. Then, the blowing fan 13 is controlled so as to have a normal exhaust air flow rate when the input of the garbage is completed and the input port 7 is closed. At this time, the deodorizing ability of the deodorizer 14 is lowered according to the exhaust air flow rate.

[0013]

According to the first aspect of the present invention, the main body of the garbage processing apparatus for decomposing the garbage with microorganisms is installed in the kitchen stand, and the garbage entrance provided on the kitchen stand surface and the above-mentioned garbage. By connecting the inside of the garbage processing tank of the processing equipment body with a duct,
A food waste processing device in which a deodorizer for heating and deodorizing and a blower fan are arranged in an exhaust path for exhausting the exhaust gas inside the food waste processing device main body. To prevent the odor from flowing back into the kitchen,
At the same time as opening the inlet, the amount of exhaust air from the blower fan was increased, and after a certain period of time, the blower fan was controlled so that the air flow rate would be the normal air volume or an exhaust air volume slightly higher than the normal air volume. When opened, the backflow of odors into the kitchen can be prevented without raising the air volume in the exhaust path so that the deodorizer can reliably deodorize and exhaust air. It is not limited to the above, but is put into the garbage processing tank.

The invention of claim 2 of the present invention is the invention of claim 1.
In the above, since the deodorizing ability of the deodorizer was controlled to change according to the exhaust air volume, it is possible to prevent the odor from flowing back into the kitchen when the inlet is opened, and it is necessary to design the deodorizer with an excessive capacity. It is also possible to reduce costs (deodorizer initial cost, electricity cost).
