Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal device for decomposing garbage (garbage) generated in a kitchen by the action of microorganisms.

[0002]

2. Description of the Related Art As a method for treating kitchen waste that is generated every day in kitchens such as general households and restaurants, there is a method utilizing microbial decomposition. The kitchen waste processing device by this method is configured by opening a kitchen input port in the upper part of the processing tank that stores the processing medium (sawdust, wood chips, etc.) suitable for the inhabitation of microorganisms, and arranging the stirring means inside the kitchen. The kitchen waste that is thrown into the treatment tank through the charging port is left in a state of being mixed in the treatment medium by the operation of the stirring means, and decomposed by the activity of the microorganisms that live in the treatment medium.

In this type of kitchen waste treatment apparatus, an appropriate amount of air (oxygen) is supplied to a treatment medium containing a proper amount of water and kept at a proper temperature, so that the inside of the treatment medium is in an environment suitable for the activity of microorganisms. It is important to keep The stirring means,
The garbage thrown into the treatment tank is evenly dispersed in the treatment medium, and the air is taken into the treatment medium. The garbage feeding port of the treatment tank is generated along with the decomposition of the garbage. In order to prevent the leakage of odors to the outside, it is closed except when the kitchen is thrown in, so the amount of air is insufficient during the above-mentioned leaving period for decomposition, and the processing capacity decreases as the habitat of microorganisms deteriorates, It causes inconvenience such as decomposition during decomposition.

Therefore, conventionally, an air supply means (air pump) for supplying outside air into the processing tank is provided, and the operation of the air supply means causes the outside air to be forcibly supplied into the processing tank to ventilate the inside of the processing medium. In order to compensate for the shortage of the air amount during the above-mentioned leaving period, the garbage disposal device configured in this way,
For example, it is disclosed in JP-A-5-221765.

Further, the internal temperature of the treatment tank is automatically adjusted by the heat generated by the activity of microorganisms for decomposing garbage,
This adjustment is affected by the air supply by the air supply means, and it becomes difficult to maintain the appropriate temperature in the cold season when the temperature of the air supply is low. Therefore, as disclosed in Japanese Patent Laid-Open No. 5-221765, an electric heater as a heating means is wound around the outside of the processing tank, and an appropriate temperature is maintained by the heat generated by the electric heater. .

[0006]

Now, in the garbage treating apparatus configured as described above, the treating capacity of the garbage is mainly dependent on the amount of the treating medium inside the treating tank, while the amount of microorganisms in the treating medium is Affected by activity. Focusing on this, in the garbage treatment device disclosed in the above-mentioned Japanese Patent Laid-Open No. 5-221765, the amount of air supply by the air supply unit is increased or decreased according to the amount of garbage input into the processing tank, and the microorganisms By adjusting the activity of, the input garbage is always decomposed under good conditions, and the amount of air supply can be increased or decreased by changing the drive voltage of the air pump that is the air supply means. ing.

However, the amount of air supplied by the air pump, which is the air supply means, is affected by the magnitude of the ventilation resistance when this air supply passes through the processing medium, and even when the air pump is driven under the same conditions, it is actually The air supply amount of the
The amount of air supply cannot be correctly controlled by the drive control of the air pump because it greatly depends on the state of the ventilation side, such as the density of the processing medium including the garbage inside.

Therefore, it is conceivable to measure the actual ventilation amount and perform feedback control based on this measurement result. However, the ventilation amount includes water and gas produced by decomposition of the garbage, and the ventilation amount Is extremely difficult to measure with high accuracy. In addition, when the measurement result of the intake amount of the air pump is used as a representative, a large error is caused depending on the magnitude of the resistance on the ventilation side, and it is difficult to perform the feedback control.

Further, it is important to maintain the inside temperature of the treatment tank at an appropriate temperature suitable for the activity of microorganisms. The inside temperature of the treatment tank changes depending on the amount and temperature of the supply air, and the above-mentioned appropriate temperature is maintained. There was a problem that became difficult. Further, when the amount of kitchen waste to be treated is small, the inside of the treatment tank is in a dry state in order to maintain the proper temperature, and the activity of microorganisms is reduced, and unnecessary power is consumed, resulting in a running cost increase. There was a problem of causing a steep rise.

That is, in the garbage processing apparatus disclosed in Japanese Unexamined Patent Publication No. 5-221765, it is difficult to increase / decrease the processing capacity according to the amount of garbage input, and a part of the input garbage under inappropriate processing conditions. Had a problem that it rots and gives off an unpleasant odor, and also requires a great running cost.

The present invention has been made in view of the above circumstances, and it is possible to accurately increase or decrease the processing capacity according to the amount of garbage to be thrown in, and it is possible to always perform the garbage treatment in an appropriate environment. It is an object of the present invention to provide a garbage disposal device which can minimize a rise in running cost due to this.

[0012]

Means for Solving the Problems The garbage treating apparatus according to the present invention mixes the garbage thrown into a treatment tank containing a treatment medium into the treatment medium and activates the microorganisms inhabiting the treatment medium. In the garbage processing device for decomposing under the contact with the outside air introduced into the processing tank, the heating means for heating the inside of the processing tank, and the temperature inside the processing tank depending on the amount of the garbage input Control means for controlling the operation of the heating means so as to maintain the target temperature is provided.

In addition, the control means operates by setting a predetermined temperature as a target temperature for a predetermined time after the garbage is put in, and achieves the target temperature by adjusting the on / off time of the heating means. Each is characterized by.

[0014]

In the present invention, the operation of the heating means for heating the inside of the processing tank is controlled according to the amount of kitchen waste to be processed, and the internal temperature of the processing tank is changed to increase or decrease the processing capacity. .

In addition, the heating means is controlled so that a predetermined target temperature is achieved for a predetermined time after the garbage is thrown, regardless of the amount of the garbage thrown, to accelerate the start-up of the decomposition treatment immediately after the throwing, and with the garbage. It kills the harmful bacteria that are input and maintains a good habitat for microorganisms.

Further, the operation control of the heating means is performed not by the quantitative control of the voltage or the current but by the simple on / off control to simplify the control system.

The activity of the microorganisms inhabiting the treatment medium 2 is affected by the ambient temperature when a proper amount of water and air are supplied, and the treatment capacity of the garbage A in the treatment tank 1 is as shown in the figure. It increases proportionally as the internal temperature rises. In addition, the white circles in the figure represent the amount of water discharged through the discharge hose 6 (water removal amount), and it can be seen that this shows a variation mode that is substantially the same as the garbage disposal amount.

Therefore, the heating control section 8 performing the above-mentioned operation
According to the apparatus of the present invention equipped with, the kitchen waste A to be put into the processing tank 1 is processed under proper processing conditions according to this amount. In addition, the internal temperature of the processing tank 1 is, in a general use state in which the garbage A is constantly charged,

The temperature sensor 20 shown in this figure has a variable resistor 22 connected in series with a thermistor 21 as a temperature sensing unit and a potential between the two. It is provided with a comparator 23 for comparing with a predetermined potential. For example, the operating knob arranged on the operating portion 7 can be operated in accordance with the input amount of the garbage A to change the resistance value of the variable resistor 22 appropriately. The output of the comparator 23 is set to the heating control unit 8
With this configuration, the temperature switch functions as a temperature switch that switches the output level of the comparator 23 before and after the temperature corresponding to this resistance value.

Therefore, the temperature sensor thus constructed is
The target temperature t in the flow chart shown in FIG.
The step of setting ₀ (step 2) and the step of comparing the internal temperature t with the target temperature t ₀ (step 9) are omitted, and the heating control unit 8 responds to the change in the output level of the temperature sensor 20 according to the change in level. It suffices to perform the operation of turning on / off the heaters H ₁ and H _{2, so} that the configuration can be further simplified.
