In this food waste processing device, take out the sample,
It is possible to know the activity status of the microorganisms in the device by pure culture or by adding a reagent or the like. Further, there is no conventional means for determining whether or not the stirring state of food waste is properly adjusted, and the control of the stirring operation relies on experience and a standard based on past data. Further, the humidity inside the machine into which the garbage is put is determined by visually observing the mixing ratio of water and the like and the degree of wetness.

[0003]

However, in the above-mentioned conventional method of knowing the activity status of microorganisms, it takes time and effort to determine whether or not the microorganisms are actively active. It is not easy to control the peripheral devices such as the air supply device, the deodorizing device, the heater, and the water supply device to create an optimal environment for microorganisms. Moreover, the stirring operation of the food waste is not always performed properly.
Furthermore, with regard to the humidity inside the machine, changes over time cannot be captured, and since it is not detected as an electrical signal only by obtaining a rough visual value, it is possible to control it appropriately according to the humidity inside the machine. Can not. Further, even if opposing electrodes are provided and a voltage is applied to measure the humidity inside the machine, the humidity cannot be accurately measured due to the influence of electric polarization and stirring. Therefore, the optimum humidity for the microorganisms cannot be maintained, and the microorganisms may not be processed due to excessive drying to reduce the activity of the microorganisms or excessive moisture to generate anaerobic bacteria.

The present invention has been made in order to solve the above-mentioned problems, and the activity status of microorganisms such as bacteria can be easily and accurately known so that the activity status of microorganisms can be improved.

[0007]

According to the control device for a food waste disposer according to the invention of claim 1 having the above structure, microorganisms such as bacteria decomposing food waste self-heat with its activity,
The more active the activity, the greater the self-heating. Further, since aerobic bacteria are generally used as effective microorganisms as microorganisms, they have the property of temporarily increasing the temperature when oxygen is supplied by stirring or the like. Therefore, the in-machine temperature detected by the temperature detecting means changes in association with the garbage processing, and it is determined whether or not the microorganisms are in the active state based on this temperature change, and a signal indicating this situation.

This temperature change becomes larger as the activity of the microorganism is more active. Therefore, it is possible to properly determine whether or not the microorganism is in the active state based on the temperature change immediately before and immediately after, and the action according to claim 1 is obtained.

Further, according to the control device for a food waste processing machine of the third aspect of the present invention, the humidity inside the machine body changes variously depending on the moisture contained in the food waste, the frequency of stirring the food waste, etc. The in-machine humidity detected by the means will fluctuate in connection with food waste disposal.

A deodorizing device 16 that removes odors inside the machine body 3 is provided in the exhaust path of the exhaust fan 15. An ozone generator or the like can be used as the deodorizing device 16. A heater 17 is installed at the bottom of the machine body 3 to warm the inside of the machine body 3 to raise the temperature. The control device 18 receives the detection signals from the temperature sensors 8, 9, 10 and the electrodes 11, 12 and controls the rotation of the stirring motor 7, the water supply by the water supply device, the deodorizing device 16, and the heater 17. Although not shown, a display panel connected to the control device 18 is installed on the outer wall of the machine body 3, and an alarm lamp 27 indicating an abnormality is displayed on the display panel.
28 (FIG. 2) is provided.

FIG. 2 is a diagram showing a control device of the garbage processing machine. The output of the oscillator 21 is given between the electrode 11 and the ground, and an alternating current is passed between the electrodes 11 and 12 and the resistor 22. The voltage obtained across the resistor 22 is applied to the preamplifier 23.
It is amplified by and input to the narrow band amplifier 24. The narrow band amplifier 24 passes only the frequency of the AC voltage applied by the oscillator 21. The signal that has passed through the narrow band amplifier 24 is input to the controller 18 via the logarithmic amplifier 25. Further, temperature detection signals from the temperature sensors 8, 9 and 10 are also input to the controller 18. The controller 18 receives these signal inputs and, as described later,
The rotation control of the stirring motor 7, the opening / closing control of the water spray valve 26 of the water sprinkler, the heating control of the heater 17, and the lighting control of the alarm lamps 27 and 28 indicating the drying or excessive water in the machine body 3 are performed.

Next, the relationship between the temperature change detected by the temperature sensors 8, 9 and 10 and the activity status of bacteria will be described with reference to FIGS. 3 to 5. When the bacteria that decompose the garbage 2 are activated, they are accompanied by self-heating, and the more intense the activity, the greater the self-heating. In addition, since aerobic bacteria are generally used as effective bacteria for bacteria that decompose food waste 2, it has the property of temporarily and rapidly increasing the temperature when oxygen is supplied by stirring or the like. There is. The temperature change when the bacteria have stopped their activity is shown in FIG.
The temperatures respectively detected by the temperature sensors 8, 9 and 10 exhibit almost the same changes. The temperature change with time is mainly the outside air temperature change, and one scale on the time axis is 30 minutes.

On the other hand, the temperature change when the bacteria are active is shown in FIG. In the figure,
The range of A is the stirring time, and the stirring operation is performed, for example, every 30 minutes, and the temperature (broken line or solid line) detected by the temperature sensor 10 or 9 greatly changes in a wavy manner in accordance with this stirring cycle. . That is, the temperature detected by the temperature sensor 10 or 9 rapidly increases immediately after stirring by stirring, and then gradually decreases, and when the stirring is restarted thereafter, it rapidly increases again immediately after stirring. The temperature change before and after stirring becomes more intense as the bacteria become more active. This remarkably appears when the temperature (dotted line) by the temperature sensor 8 that detects a temperature close to the overall temperature of the machine body 3 decreases.
Further, when the stirring operation is sufficiently performed, as shown in FIG. 4, a wave of the temperature detected by the temperature sensor 9 (solid line),
The waves of the temperature detected by the temperature sensor 10 (broken line) substantially match.
On the other hand, even if the bacteria are actively active, if the stirring operation is not sufficiently performed, the temperatures detected by the temperature sensor 9 and the temperature sensor 10 change according to the stirring cycle, as shown in FIG. , There is a difference in their average value. From the above, it is possible to know the degree of activity of bacteria by the magnitude of the temperature change before and after the intermittent stirring of the temperature sensor 10 or 9, the temperature difference between the average values of the temperatures detected by the temperature sensors 9 and 10. Based on this, the controller 1
8 can optimally control the intermittent drive cycle and time of the agitation motor 7, the air supply amount by the intake fan 14, and the deodorizing operation by the deodorizing device 16.

[0015] Sawdust and barley may be added together with the raw garbage 2. If the stirring of the raw garbage 2 is excessive, the sawdust and the malt will be overdried, and the activity of bacteria will be adversely affected. However, electricity consumption also increases. In addition, if the garbage 2 is not agitated sufficiently, oxygen will not fully spread in the garbage 2, so the humidity at the bottom of the aircraft 3 will rise, anaerobic bacteria will propagate, and in the worst case, water will accumulate and bacteria will die. To do. Thus, the degree of agitation is very important,
By utilizing the properties described in the description of FIGS. 3 to 5, the stirring control can be optimized based on the change in the temperature detected by the temperature sensors 8, 9, 10. In addition, the environment of bacteria that decomposes the garbage 2 is said to have an optimum humidity of about 60%. If it is less than 30%, the activity is reduced, and further, sawdust and barley powder mixed with the garbage 2 are scattered, and the area is polluted and the fan is clogged. When it is 80% or more, ammonia and anaerobic bacteria are easily generated, which shortens the life of bacteria.

Next, the control procedure for displaying the bacterial activity status by the controller 18 according to the activity status of bacteria will be described with reference to the flowchart of FIG. First,
The temperature is measured by the temperature sensors 8 and 10 (S1), and the temperature change of the temperature sensor 8 over time is checked (S1).
2). When the temperature of the temperature sensor 8 is decreasing, the temperature of the temperature sensor 10 is drastically changed. Therefore, it is checked whether or not the temperature of the temperature sensor 8 is decreasing (S3). If it is not decreasing (S3: NO), If the process returns to S1 and is descending (S3: YES), the temperature T10 immediately before stirring is measured by the temperature sensor 10 (S4), the temperature T2 immediately after stirring is measured (S5), and the temperature T2 and the temperature are measured. The temperature difference T3 of T1 is calculated (S6). The temperature difference T3 is a predetermined temperature (high), for example, 4 ° C
Is larger than the predetermined temperature (S7: YES), or if the temperature difference T3 is not larger than the predetermined temperature (S7: N).
O), the temperature difference T4 between the average temperature of the temperature sensor 10 and the temperature of the temperature sensor 8 is calculated, and when the temperature difference T4 is larger than a predetermined temperature (high), for example, 3 ° C. (S8, S9: Y).
ES), since the activity of bacteria is active and the odor becomes strong, the deodorizing device 16 is made to operate strongly (S10), the rotation amount of the intake fan 14 is made weak (S11), and bacteria (bacteria) become active. A lamp indicating that it is active is turned on (S12). As described above, the amount of rotation of the intake fan 14 is weakened in order to reduce the supply amount of air so that the degree of bacteria activity is not excessive and adverse effects are not caused.

The temperature difference T3 between the temperatures T2 and T1 is not larger than the predetermined temperature (S7: NO), and the temperature difference T4 between the average temperature of the temperature sensor 10 and the temperature of the temperature sensor 8 is larger than the predetermined temperature. When the temperature difference T3 is not present (S9: NO), and the temperature difference T3 is higher than a predetermined temperature (low), for example, 0.5 ° C. (S13: YES), the bacteria are in a normal activity state. The operation is started (S14), the rotation amount of the intake fan 14 is set in parallel (S15), and the lamp indicating that the bacteria are normally active is turned on (S16).

Average temperature of temperature sensor 10 and temperature sensor 8
The temperature difference T4 from the temperature is a predetermined temperature (low), for example 0.5.
When the temperature is higher than ℃ (S17: YES), the activity state of the bacteria is weak, so the deodorizing device 16 is set to a weak operation (S18), the rotation amount of the intake fan 14 is increased (S19), and the activity status of the bacteria is The lamp indicating weak is turned on (S20).
Further, when the temperature difference T4 is lower than a predetermined temperature (low), for example, 0.5 ° C. (S17: NO), since the activity of the bacterium is stopped or has reached the end of life, the operation of the deodorizing device 16 is stopped (S2).
1) The rotation of the intake fan 14 is stopped (S22), and the alarm lamp indicating that the activity of the bacteria has stopped is turned on (S23). As described above, it is possible to control the deodorizing device 16 and the intake fan 14 and display the bacteria activity according to the activity status of bacteria.

Next, the control procedure of the stirring operation by the controller 18 will be described with reference to FIGS. Figure 7
Is a flow chart showing a procedure for stirring control based on the temperature detection results of the temperature sensors 8, 9 and 10. The temperature is measured by the temperature sensors 8, 9 and 10 (S31),
Examine the temperature change of the temperature sensor 8 with the passage of time (S3
2). It is checked whether or not the temperature of the temperature sensor 8 is decreasing (S33). If the temperature is decreasing (S33: YES), the average values T5 and T6 of the temperature sensors 9 and 10 are calculated (S34), and the average value is calculated. The difference T7 between the values T5 and T6 is calculated (S
35). When the difference T7 is larger than a predetermined value (high), for example, 3 ° C. (S36: YES), stirring by the stirring means is insufficient, so the stirring cycle is shortened (S37). The above-described operation is performed by shortening the stirring cycle until the stirring cycle reaches the minimum setting, for example, 10 minutes. The stirring time at that time is, eg, 3 minutes. Even if the stirring cycle is set to the minimum,
When the stirring is still insufficient (S38: YES), the stirring time is lengthened (S39). The above-mentioned operation is performed by lengthening the stirring time until the stirring time reaches the set maximum time, for example, 10 minutes. Even if the stirring time is set to the maximum, if the stirring is still insufficient (S40: YES), an abnormal operation or failure may be considered, so the alarm lamp is turned on (S41). If NO in process S38 or S40, the process returns to S31.

When the difference T7 between the average values T5 and T6 is smaller than a predetermined value (low), for example, 1 ° C. (S42: YE
S), because the agitation is over, contrary to the above case,
The stirring cycle is lengthened (S43). The above-described operation is performed by lengthening the stirring cycle until the stirring cycle reaches the set maximum, for example, 30 minutes. The stirring time at that time is, eg, 3 minutes. Even if the stirring cycle is set to the maximum, if the stirring is still over (S44: YES), the stirring time is shortened (S4).
5). Until the stirring time reaches the set minimum time, for example, 1 minute, the stirring time is shortened and the above operation is performed. Even if the stirring time is set to the minimum, if the stirring is still excessive (S4
6: YES), because an abnormal operation or a failure is considered, the alarm lamp is turned on (S41). Process S42,
If NO in S44 or S46, the process returns to S31. When the stirring operation is normally performed without excess or deficiency, both the process S36 and the process S42 are NO, and the loop returning to the process S31 is repeated. As described above, the garbage can be appropriately stirred by controlling the stirring means according to the activity status of the bacteria detected based on the temperature change, so that the decomposition processing of the garbage by the bacteria can be optimized.

FIG. 8 is a flow chart showing the procedure for stirring control based on the results of the humidity detected by the electrodes 11 and 12. The voltage is measured by the electrodes 11 and 12 and the resistor 22 (S51), and the level fluctuates slightly with each stirring, so the average value V1 for five times is taken (S52). When this average value V1 is larger than a predetermined value (large), for example, 5 V (S53: YE
S) Since it is too wet, the stirring cycle is shortened to increase water divergence (S54). The above-described operation is performed by shortening the stirring cycle until the stirring cycle reaches the minimum setting, for example, 10 minutes. The stirring time at that time is, eg, 3 minutes. Even if the stirring cycle is set to the minimum, if it is still too wet (S55: YES), the stirring time is lengthened (S56).
The above-mentioned operation is performed by lengthening the stirring time until the stirring time reaches the set maximum time, for example, 10 minutes. Even if the stirring time is set to the maximum, if it is still too wet (S5
7: YES), the heater 17 is turned on (S58). If the heating temperature by the heater 17 is maximized and the temperature is too high (S59: YES), an abnormal operation or failure may occur, so the alarm lamp 28 indicating excessive water is turned on (S60). If NO in step S55, S57 or S59, the process returns to step S51.

When the average value V1 for five times is smaller than a predetermined value (small), for example, 1 V (S61: YE
S) Since it is too dry, the stirring cycle is lengthened, contrary to the case of being too wet (S62). The above-described operation is performed by lengthening the stirring cycle until the stirring cycle reaches the set maximum, for example, 30 minutes. The stirring time at that time is, eg, 3 minutes. Even if the stirring cycle is set to the maximum value, if it is still too dry (S63: YES), the stirring time is shortened (S64). Until the stirring time reaches the set minimum time, for example, 1 minute, the stirring time is shortened and the above operation is performed. Even if the stirring time is set to the minimum, if it is still too dry (S65: YES), the water spray valve 26 is opened, and water from the water supply device is sprayed to replenish the water content (S66). If the amount of water supplied by the sprinkler is maximum, but the amount of water is too dry (S67: YES), an abnormal operation or failure may occur, so the alarm lamp 27 indicating the dryness is turned on (S60). In the case of NO in process S61, S63, S65 or S67, the process returns to S51. When the stirring operation is normally performed without excess or deficiency, both the process S53 and the process S61 are NO, and the loop returning to the process S51 is repeated. By controlling as described above, it is possible to prevent the garbage from being unable to be treated due to excessive drying to reduce the activity of bacteria and excessive moistening to generate anaerobic bacteria.

The present invention is not limited to the above embodiment, and various modifications can be made. For example, the stirring operation by the stirring means may be substantially intermittently driven. For example, continuous driving may be performed periodically. It also includes driving that switches between strength and weakness.
Further, in the garbage processing device 1 of the above-mentioned embodiment, the one provided with the temperature sensor 8, 9, 10 and the humidity sensor composed of the electrodes 11, 12 is shown. However, even if only the temperature sensor is provided, only the humidity sensor is provided. May be provided. Furthermore,
You may make it control by combining the detection signal from both sensors. Further, in the above-mentioned embodiment, the one in which the stirring and the like are automatically controlled according to the activity status of the bacteria is shown. However, the operator sees the display of the activity status of the bacteria displayed on the alarm lamps 27 and 28. Alternatively, the stirring operation may be manually controlled. The present invention also includes such a manual stirring control. Further, it is ideal that the temperature sensors are provided at three locations in the machine body 3 as in the above-mentioned embodiment, but at the minimum, only the temperature sensor 10 may be provided. In that case, immediately after and immediately before the intermittent stirring operation. The degree of stirring may be controlled according to the magnitude of change in the temperature detected by the temperature sensor 10.

In addition, in the above-mentioned embodiment, it is assumed that bacteria are put into the machine body 3 together with the garbage 2, but the bacteria are not put in and decomposed by using the bacteria adhering to the garbage. May be Further, the predetermined values in the flowcharts of FIGS. 6 to 8 are not limited to the values of the above embodiment. Further, in order to display an abnormal operation or the like, the alarm lamp 2 is used in the above embodiment.

As described above, according to the control device for a food waste disposer according to the invention of claim 1 or 2, the in-machine temperature which fluctuates in connection with the disposition of food waste is detected, and bacteria are detected based on this temperature change. Since the signal related to the activity status of microorganisms such as, for example, is obtained and the stirring operation of the garbage inside the machine is controlled according to this signal, the above temperature change is related to the activity of the garbage processing activity by the microorganisms. This property can be utilized to allow the microbial decomposition of food waste to be appropriately performed. Therefore, it is possible to create an optimal environment for microorganisms and efficiently decompose food waste. Also, in the past, there was no means to judge whether or not the stirring condition of food waste was properly adjusted, so stirring control relied on experience and criteria, but it is necessary and necessary to carry out stirring. This makes it possible to prolong the life of microorganisms and reduce the amount of electricity used.

In response to this signal, the stirring operation of the food waste inside the machine is controlled, so that an optimal environment for microorganisms can be created and the food waste can be efficiently decomposed. Therefore, it is possible to treat food waste without drying it too much and reducing the activity of microorganisms. Further, it is prevented that anaerobic bacteria are generated due to excessive moistening and that wastewater cannot be treated due to accumulation of sewage in the lower part.
