Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to kitchen waste (garbage).
The present invention relates to an organic substance processing apparatus for decomposing organic substances such as microorganisms using microorganisms.

[0002]

2. Description of the Related Art An organic matter processing apparatus that decomposes organic matter such as kitchen materials by microorganisms cultured on a carrier (often wood chips such as sawdust) is required to maintain an environment suitable for the activity of microorganisms in a treatment tank. is important. Therefore, conventionally, a fan that takes in outside air into the inside of the processing tank and a heater that heats the inside of the processing tank have been provided. With the fan and the heater, the amount of air and the amount of water in the processing tank have been appropriately maintained, and the inside of the processing tank has been maintained. The target temperature is maintained. Since outside air is taken into the processing bath, it is necessary to consider the outside air temperature when controlling the temperature of the heater in order to maintain the inside of the processing bath at the target temperature.

Generally, when the outside air temperature is lower than a predetermined temperature, the heater is turned on / off by a temperature detector such as a thermistor disposed on the heater core wire. The amount of heat supplied to the heater becomes substantially constant.

[0004] Therefore, in winter or the like when the outside air temperature is low, the amount of heat supplied from the heater is insufficient because cold outside air is supplied into the processing tank, and the temperature of the carrier in the processing tank decreases. However, there is a disadvantage that the organic matter treatment efficiency is deteriorated.

[0005] In spring or autumn, for example, in which the outside air temperature is slightly lower than a predetermined temperature which is a reference for judging the necessity of energizing the heater, the temperature of the carrier in the processing tank is reduced by the amount of heat supplied excessively from the heater. When the temperature is too high, the activity of microorganisms is reduced, the efficiency of treating organic substances is deteriorated, and the electric power for the heater is disadvantageously consumed.

[0006] As an organic substance processing apparatus which has solved such a defect, Japanese Patent Application Laid-Open No. 9-290237 (B09B3
// 00). In this configuration, the temperature detecting portion of the heater facing the air flow path for taking in outside air into the processing tank is separated from the heater core by a predetermined distance (27 mm in this device). It is susceptible to the outside air that flows in from the mouth. When the outside air temperature is low, the temperature detection unit is cooled, so the duty ratio of the heater is increased. Conversely, when the outside air temperature is high, the duty ratio of the heater is reduced, and it works as if it has an outside air temperature detection unit. It is.

[0007]

By the way, when the amount of the organic substance such as the kitchen is small with respect to a certain amount of the carrier, the water content (moisture content) in the entire processing tank is reduced, so that the drying is prevented. It is necessary to control so as to suppress the amount of water evaporation for the purpose. As a method for controlling the amount of water evaporation according to the amount of organic matter input into the kitchen or the like, there are methods such as changing a heater temperature setting value and reducing the amount of ventilation by a fan. Intermittent operation of fans is often performed. In the related art, the fan is operated intermittently when the input amount is small.

In this method, when the outside air temperature decreases and cool air flows in from the intake port, the temperature detecting section is cooled and the heater is continuously energized. , Indicates that the temperature detector has not reached the set temperature value. If the fan is operated intermittently in this state and the ON time of the fan is shortened, the heater surface temperature is equal to the uncontrolled state (continuous energized state). Then, a problem occurs that the temperature reaches a dangerous temperature (100 ° C. or higher).

FIG. 16 is a graph showing changes in the heater surface temperature when the outside air temperature is high and when the outside air temperature is low, with the temperature set value of the above-mentioned temperature detection unit being 31 ° C. The broken line indicates when the outside air temperature is high, and the solid line indicates when the outside air temperature is low. Each unevenness is due to the intermittent operation of the fan, the concave portion is when the fan is ON, and the convex portion is the fan OF.
It is F time.

That is, when the input amount of the organic matter is small,
At this time, if the outside air temperature is low, the temperature detection unit of the heater is cooled and the air flow repeats inflow and stop due to the intermittent operation of the fan. If the surface temperature is dangerous (10
0 ° C. or higher).

Therefore, the present invention has been made to solve such a problem, and the advantage of separating the temperature detecting portion of the heater from the heater core by a predetermined distance is utilized. It is an object of the present invention to provide an organic material processing apparatus capable of preventing the heater surface temperature from rising to a dangerous temperature even when the outside air temperature is low, when the ventilation rate is reduced by intermittent operation of the apparatus.

The outlet 39 is openably and closably covered by an outer cover 40.

In this embodiment, the control board 27
On the top surface of the upper case 13 located at the upper part of the table, the three-stage operation mode of "strong", "standard", and "weak" as shown in FIG. Switch 41 for turning on and off each of the operating states.
An operation display unit 43 having a display unit 42 including a plurality of LEDs and the like is provided. Switch 41 and display unit 42
Is connected to the control board 27, is attached to the cover 32 covering the control board 27, and is disposed on the operation display section 43 on the top surface of the upper case 13.

In this apparatus, since the processing amount (input amount) of the organic matter such as the kitchen and the appropriate ventilation amount for the processing amount are as shown in FIG. 12, when the processing amount is equivalent to the maximum of 1200 g, the ventilation is required. 100% (fan continuous operation), when the processing amount is equivalent to the standard 700 g, the ventilation volume 50% (fan O
When the N / OFF ratio is a 1: 1 intermittent operation of the fan) and the processing amount is a small amount equivalent to 300 g, the ventilation volume is 20% (fan ON / OFF).
The intermittent operation of the fan having an OFF ratio of 1: 4) can be set in three stages.

As shown in FIG. 11, a temperature setting for controlling the planar heater 5 by using the temperature detecting thermistor 7a in accordance with the amount of organic matter (ventilation) of the above-mentioned kitchen or the like. The value is determined, and two kinds of high and low temperature set values are switched according to the outside air temperature detected by the outside air temperature detection thermistor 7b. The outside air temperature at the time of switching is set to 13 ° C. in this embodiment, and is switched to a higher temperature set value when the outside air temperature is higher than 13 ° C. and to a lower temperature set value when the outside air temperature is 13 ° C. or less. It has become.

More specifically, as shown in FIG. 11, since the ventilation is 100% during the strong operation, the temperature set value does not change at 35 ° C. at the high and low, but the ventilation is 50% during the standard operation.
The higher temperature set value is 31 ° C, the lower temperature set value is 25 ° C, and the ventilation is 20% during weak operation, the higher temperature set value is 31 ° C, and the lower temperature set value. Becomes 21 ° C.

In the above configuration, when using the present apparatus, a certain amount of the microorganism carrier 4 is previously charged into the treatment tank 1. And when processing organic matter such as kitchen garbage,
The upper lid 25 is opened, and organic matter such as kitchen waste is charged into the processing tank 1 from the input port 24, and the operation mode switch 41 of the operation display unit 43 is set to any one of “strong”, “standard”, and “weak” in accordance with the amount. The upper cover 25 is closed after confirming that the corresponding display section 42 is turned on. When the upper lid 25 is closed, this is detected by detection means (not shown), and the control unit mounted on the control board 27 starts energization control to the sheet heater 5, the electric motor 15, and the ventilation fan 30 based on the output. .

Here, when the input amount of organic matter such as garbage is equivalent to 1200 g, which is the maximum processing amount of the present apparatus (during the strong operation mode), the energizing control of the electric motor 15 is performed in the same manner as in the prior art, so that the stirring member Rotates intermittently forward and reverse to stir and mix the carrier 4 and the organic matter, and to control the temperature in the processing tank 1 by controlling the energization of the sheet heater 5 at a temperature set value of 35 ° C. regardless of the outside air temperature. The organic matter is decomposed into carbon dioxide and water by the microorganisms cultured on the carrier 4 and composted while maintaining the range within the optimum range for the activation of the microorganisms.

The ventilation fan 3 having a ventilation volume of 100%
By controlling the continuous energization to 0, the humid air in the processing tank 1 is discharged to the outside to prevent the processing tank 1 from being humidified, and the air in the processing tank 1 is discharged to the outside. Accordingly, outside air is taken into the main body case through an intake port 12 formed in the lower case 11, and oxygen necessary for activating microorganisms is supplied into the processing tank 1 from a suction port 9 formed in the upper part of the processing tank 1.

On the other hand, the input amount of organic matter such as kitchen waste is
When it is equivalent to 00g (in the standard operation mode), the ventilation fan 3
0 is an intermittent operation with a ventilation rate of 50% (fan ON / OFF ratio is 1: 1), and the thermistor 7b for detecting the outside air temperature.
When the outside air temperature is higher than 13 ° C according to the detected temperature of
The temperature set value of the heater temperature detecting thermistor 7a is set to 31 ° C.
When the outside air temperature is as low as 13 ° C or less, the temperature set value is set to 2
At 5 ° C., energization control of the planar heater 5 is performed so as to suppress an increase in the heater surface temperature due to the intermittent operation of the fan when the outside air temperature is low.

Further, when the input amount of organic matter such as kitchen garbage is a small amount equivalent to 300 g (during the weak operation mode), the ventilation fan 3
0 is an intermittent operation of 20% ventilation (fan ON / OFF ratio is 1: 4) and the thermistor 7b for detecting outside air temperature
When the outside air temperature is higher than 13 ° C according to the detected temperature of
The temperature set value of the heater temperature detection thermistor 7a is 31 ° C.
However, when the outside air temperature is as low as 13 ° C. or less, the temperature set value is further lowered to 21 ° C. so as to suppress a sudden rise in the heater surface temperature due to the intermittent operation of the fan with a ventilation rate of 20% when the outside air temperature is low. The energization control of the planar heater 5 is performed.

In the above, at the time of weak operation in which the heater surface temperature is likely to rise to the most dangerous temperature (100 ° C. or higher),
The change in the heater surface temperature when the outside air temperature is high and when it is low is measured and graphed as shown in FIG. 13. The heater surface temperature when the outside air temperature is low (shown by a solid line) is changed to the heater when the outside air temperature is high. The temperature was almost the same as the surface temperature (shown by a broken line), and the temperature did not reach the dangerous temperature (100 ° C. or higher).

That is, if the operation is weakened when the outside air temperature is, for example, −5 ° C. by controlling as described above, conventionally, the temperature set value was a constant 31 ° C. regardless of the outside air temperature. As shown in FIG. 13, when the outside air temperature was low, the heater surface temperature exceeded 100 ° C., but by switching the heater temperature set value when the outside air temperature was low as in this embodiment, as shown in FIG. The heater surface temperature can be made substantially constant regardless of the outside air temperature, and the heater surface temperature can be prevented from rising to a dangerous temperature.

In this embodiment, both the ventilation volume and the temperature set value can be switched and set by one operation of one operation mode switch 41, so that the operation is very simple.

Although the present apparatus is generally installed outdoors, the thermistor 7b for detecting the outside air temperature is provided in the air flow path which is not affected by the sheet heater 5 in the main body case. It is possible to accurately detect the outside air temperature without being affected by such factors.

Further, in this embodiment, since the angle formed by each of the rotary blades 21 of the agitator 18 is an obtuse angle at only one place, the bag is packed as shown in FIGS. The stirring blades 21 can easily store the packed carriers 4 to be stored in the processing tank 1 without disturbing them. In this case, in order to prevent the storage bag 4a from being broken or the like, the cardboard material 45 inserted between the stirring blade 21 and the carrier storage bag 4a can be easily inserted, and the packing operation is considerably simplified.

In the above-described embodiment, the planar heater 5 in which the heater core wire 5b is embedded in the sheet-like base material 5a is used. However, the present invention is not limited to this. Can be applied to various types of heaters, such as those provided on the outer wall of the processing tank 1.

In the above embodiment, the ventilation fan 30
Although the air volume (ventilation volume) is controlled by the intermittent operation, the air volume (ventilation volume) may be controlled by reducing the rotation speed of the ventilation fan 30.

A switching section for switching a preset temperature set value in accordance with the above, intermittently operating the fan with a small amount of organic matter input while taking advantage of the advantage of separating the heater temperature detection section from the heater core wire by a predetermined distance. For example, when the ventilation rate is reduced, the heater surface temperature can be prevented from rising to the dangerous temperature even if the outside air temperature is low.

Further, the switching section switches between the ventilation amount and the temperature set value in accordance with the amount of the organic substance charged and the outside air temperature detected by the outside air temperature detecting section. In addition, since both the ventilation volume and the temperature set value can be switched and set, the operation becomes very simple.

Further, since the outside air temperature detecting section is provided in the air flow path that does not pass through the heater portion in the main body case, even if the apparatus is installed outdoors, it is not affected by direct sunlight or the like. An accurate outside air temperature can be detected.
