Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste processing apparatus for decomposing food waste by utilizing the power of microorganisms, and particularly for decomposing food waste such as cooking waste generated in a home kitchen. The present invention relates to a garbage processing device.

[0002]

2. Description of the Related Art Conventionally, microorganisms have been used to decompose (ferment) food waste containing organic matter and water to such an extent that it does not affect the environment. Waste disposal devices are known.

[0003] This food waste disposing apparatus, for example, puts the food waste into a food waste disposal tank filled with food waste disposing material and decomposes the food waste. It has strong mode, standard mode, weak mode, and weakest mode, and the water content sensor detects the water content of the food processing material filled in the food processing tank,
It is controlled to automatically perform the decomposition treatment operation in the decomposition treatment operation mode according to the water content. Further, a lid provided with an input port for feeding raw garbage into the raw garbage processing tank is opened to feed the raw garbage, and the opening / closing of the lid makes it possible to judge the input of the raw garbage.

The water content sensor has a heater and a temperature sensor, and the temperature of the raw garbage processing material is measured by the temperature sensor at the same time when the stirring of the raw garbage processing material in the raw garbage processing tank is completed, and then the heater. The food waste treatment material is heated for a certain period of time, the temperature of the food waste treatment material after heating is measured, and the water content is measured by the temperature rise value during that time. That is, when the temperature rise value is large, the drying progresses and the water content is low, and when the temperature rise value is small, the water content is high and the water content is high.

In the above conventional example, the operation is controlled as shown in FIG. For example, in the weak mode, the water content is detected every fixed number of times of stirring by the stirring means, and the water content is 65%.
When more than% is detected, it shifts to the standard mode, and after shifting to the standard mode, if the number of detections with the water content of 65% or more is 11 times or more in the past 16 times, it is controlled to shift to the strong mode. Was there. When the water content of 65% or more in the strong mode is less than 11 times in the past 16 times, the mode is switched to the standard mode, and the detection of the water content of 65% or more after the mode is switched to the standard mode is detected 16 times in the past. 4 hours 50 less than 3 times
If the lid has been closed for 72 hours or more after moving to the weak mode after a lapse of minutes, it shifts to the weakest mode if the lid stays closed for more than 72 hours. Controlled to move to.

Here, the strong mode, the standard mode, and the weak mode are, for example, as shown in Table 1, where the stirring frequency, the temperature control of the chips as the food waste treating material, and the air volume are changed.

[0008]

By the way, the above-mentioned water content sensor detects the water content of the food waste treating material itself when the food waste treating material is in contact with the sensor itself, and operates in an operation mode suitable for the water content. Is to be transferred to. However, for example, when about 2 kg of food waste was thrown in at one time, the food waste treatment material itself had a sudden increase in water content and was in a dumpling state, whereby voids were created and accurate sensing could not be performed. In some cases, when voids are created and sensing is not successful, the food waste treatment material becomes acidic, decomposes anaerobically, and emits a foul odor. This may give the user discomfort.

The present invention has been made in view of the above points, and even if the water content of the food waste treating material itself is suddenly increased and the food waste treating material is in a dumpling state, it is detected and appropriate operation is performed. It is an object of the present invention to provide a food waste processing device capable of performing the above.

FIG. 2 is a schematic perspective view of a food waste processing device. Inside the casing 3, a food waste processing tank 1 filled with a food waste processing material such as wood chips is provided. Inside the food waste processing tank 1, a stirring means 5 rotated by a motor 4 is provided.
Is provided. An upper opening of the raw garbage processing tank 1 communicates with a charging port 6 provided on the upper surface of the casing 3, and the charging port 6 is provided with a lid 7 that can be opened and closed. Further, an air supply port 8 is provided in the upper part of the food waste processing tank 1, and an exhaust means 9 is further provided in the food waste processing tank 1. This exhaust means 9 is different from that of the embodiment shown in FIG. An exhaust section 9a provided on the upper part of the garbage processing tank 1 and provided with an exhaust fan,
Exhaust duct 9b connected to exhaust unit 9a and exhaust duct 9
It is composed of a deodorizing device 9c provided in b. Further, the food waste processing apparatus of the present invention is provided with a heating means 10 for raising the temperature inside the food waste processing tank 1, and in the example shown in FIG. A heater 10a is provided as a heating means. Further, a water content sensor 11 is provided in the food waste processing tank 1 as a water content measuring means for measuring the water content of the food waste processing material in the food waste processing tank 1.

As described in the conventional example, the water content sensor 11 has a heater and a temperature sensor, and the temperature of the food waste treating material is controlled at the same time as the stirring of the food waste treating material in the food waste treating tank 1 is completed. The temperature sensor is used to measure the temperature, the heater is then used to heat the food waste treatment material for a certain period of time, the temperature of the heated food waste treatment material is measured, and the water content is measured by the temperature rise value during that time. Further, in the case of the present invention, it has a means for detecting whether or not the raw garbage processing material is in a dumpling state, but in the case of the example of the present embodiment, the water content sensor 1
It is also used as 1. When the temperature rise value is measured with the moisture content sensor 11, the graph is as shown in FIG. 4, but when the raw garbage processing material is in a dumpling state, the raw garbage processing material comes into contact with the moisture content sensor 11 or touches it. As a result, the temperature rise value varies and the variation range ΔT of the temperature rise value increases. That is, the temperature increase value is low when the food waste treatment material is in contact with the water content sensor 11, and the temperature increase value is high when the food waste treatment material is not in contact with the water content sensor 11. Then, by determining the variation in the temperature rise value, it is possible to determine whether or not the food waste treating material has a dumpling shape.

FIG. 3 is a control block diagram of the food waste processing apparatus of the present invention. In the figure, 2 is a control means for controlling the operation of the entire apparatus, 12 is an operation part, 13 is a determination means for determining the information detected by the water content sensor 11, and determination means. Information on the determination made by 13 is input to the control circuit forming the control means 2. There are four operation modes for decomposition processing of the food waste treatment device: strong mode, standard mode, weak mode, and weakest mode, and the water content depends on the temperature rise value of the food waste processing material measured by the water content sensor 11. The determination unit 13 determines whether the rate or the dumpling state of the food waste processing material, and based on this determination information, the control unit 2 automatically selects one of the strong mode, the standard mode, the weak mode, and the weakest mode. Select to control the operation. Here, the strong mode, the standard mode, and the weak mode are the normal food waste disposal operation modes, and the weakest mode is the operation mode when the food waste is not thrown in, such as when the house is away. . The normal mode, that is, the strong mode, the standard mode, and the weak mode, which are the operation modes of the garbage processing, are controlled as shown in Table 1 above. Further, the food waste disposing device is provided with a discontinuation lamp 14, and when it is determined that the food waste disposing material is in a dumpling state, the discontinuation lamp 14 is turned on by the control means 2 to discontinue disposing of the garbage. When it is judged that the dumpling is not in the dumpling state, the charging stop lamp is turned off.

In the present invention, when the dumpling state of the food waste processing material is detected during the operation in the standard mode, the control mode is changed from the standard mode to the strong mode and the charging stop lamp 14 is turned on. It is controlled by 2. Further, when the dumpling state is detected, if the operation mode is the strong mode, the control means 2 controls so that the closing lamp 14 is turned on. Further, when the width ΔT of the variation in the temperature rise value becomes equal to or more than a predetermined temperature difference, it is determined that the dumpling state. Further, when the variation width ΔT of the temperature rise value is less than a predetermined value, the closing lamp 14 is turned off and the operation mode is controlled to shift to the standard mode.

The operation will be described below with reference to the example shown in FIG. For example, in the weak mode, the water content is detected by detecting the temperature rise value with the water content sensor 11 every constant number of times of agitation by the agitation means 5, and when the water content is 65% or more, the mode is shifted to the standard mode. After shifting to the standard mode, if the number of times of detection of the water content of 65% or more is 11 times or more in the past 16 times, it is controlled to shift to the strong mode. Also, the water content in strong mode is 65%.
If the above is less than 11 times in the past 16 times, it shifts to the standard mode, and the moisture content after shifting to the standard mode is 65%.
If the above detection is less than 3 times in the past 16 times and 4 hours and 50 minutes have passed, the mode shifts to the weak mode, and if the lid 7 remains closed for 72 hours or more after shifting to the weak mode, the weakest mode. When the lid 7 is opened in the weakest mode, the control is controlled to shift to the weak mode. Also water content sensor 1
By judging the width ΔT of the variation of the temperature rise value detected in 1, it is judged whether the garbage processing material is dumpling-like,
The operation is controlled by the control means 2 as follows. When the width ΔT of the variation of the temperature rise value of the past 16 times is ΔT = 7 deg or more, it is determined that the dumpling state is set, and the operation mode is switched from the standard mode to the strong mode. The past 1 at this time
The width ΔT of the variation of the temperature rise value of 6 times is ΔT = 7 deg
If less than 25 deg is 12 times or more in the past 16 times, the discontinuation lamp 14 is turned on to prompt the discontinuation of disposing of garbage. Further, when the width ΔT of the variation of the temperature rise value of the past 16 times becomes ΔT = 7 deg or less, it is determined that the dumpling state is lost, and the operation mode is switched from the strong mode to the standard mode. The operation mode is switched from the strong mode to the weak mode, and the width ΔT of the variation in the temperature rise value is ΔT =
When it becomes 7 deg or less, the discontinuation lamp 14 is extinguished, and the garbage is ready to be supplied.
