Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste disposer for reducing the amount of food waste that has been thrown in, and more specifically, to deal with variations in the water content of thrown food waste with a simple operation by the user. The present invention relates to a food waste disposer capable of controlling the water content and reliably reducing the volume of food waste day by day, and an operating method thereof.

[0002]

2. Description of the Related Art Originally, food waste including food waste, food scraps, food scraps, vegetable and fruit scraps, and bones and shells of seafood are often incinerated at incineration facilities. It was However, since such garbage contains a large amount of water, it lowers the temperature of the incinerator and causes a decrease in combustion efficiency, and since it contains various components, it causes dioxins.

Therefore, a food waste processing machine has been already proposed as a device for reducing the amount of food waste, and the main types thereof are generally so-called microbial decomposition type and dry type. Among them, in the microbial decomposition type garbage disposal, for example, as described in JP-A-10-43723, a treatment medium (fermentation medium) containing microorganisms is stored in a treatment container (fermentation tank). For example, by throwing raw garbage once a day into the fermentation medium in the fermenter, the microorganisms in the fermentation medium decompose the raw garbage to reduce (or reduce) the volume.

[0004]

The capacity of food waste processing machines to reduce the volume of food waste is not always constant, and varies greatly depending on, for example, whether or not the environment is suitable for the aforementioned microorganisms to exert its capacity sufficiently. come. Humidity (moisture content), temperature, etc. are typical examples of the environmental factors, but the water content may vary greatly depending on the type of food waste to be put in.

On the other hand, according to the so-called Food Recycling Law that came into effect in May 2001, it is typified that a numerical target for recycling is imposed on food-related businesses whose food waste is 100 tons or more per year. Thus, in recent years, the momentum of food recycling has shown an increasing trend. Under such a trend, in recent years, especially in the case of large-scale food waste processing machines for business use, it is possible to accurately grasp and manage the food waste processing status (volume reduction status), and aim for a large amount and efficient processing. It is strongly desired that the volume of garbage can be reduced surely day by day. And for that purpose, since it is important to create a suitable environment for the microorganisms to exhibit a good fermentation action as described above, the water content of the daily input garbage can be changed with a simple operation by the user. It is desirable to be able to handle variations in detail, and to perform reliable and efficient volume reduction processing.

[0006] In the above prior art, in order to create a suitable environment for microorganisms, the target weight (weight) for reducing the volume of raw garbage is treated.
Set, and the panel heater installed on the wall of the fermenter and the blowing of heated air into the fermenter are controlled so that the amount of food waste detected in the fermenter reaches the target weight reduction, and the moisture is volatilized. It is like this. However, in this conventional technique, control of the water content as described above is considered, for example, on a weekly basis, and even if the water content of the input garbage varies, the manual operation of the panel heater is not changed without changing the target mass. It can be handled by on / off operation and manual blowing / interruption of heated air into the fermentation tank.
As described above, no particular consideration has been given to the daily control of the fine water content for the purpose of creating a suitable environment for the above-mentioned microorganisms, so that the aforementioned recent needs cannot be sufficiently met.

The present invention has been made in view of the above matters, and an object thereof is to easily control the water content in accordance with the variation in the water content of input garbage by a user's simple operation. (EN) It is intended to provide a food waste processing machine and a method of operating the same that can surely reduce the volume of food waste day by day.

In step 310, a drive signal is output to the closing drive device 97 to start descending the container table 95b. As a result, the emptied container 96 gradually descends from the top.

After that, in step 311, the descending container table 95b is moved to the middle position sensor 9 of the reversing loading device 95.
When it is confirmed that the detection signal has been turned on after passing the position 5c, the process proceeds to step 312, and the opening / closing drive device 11
A driving signal is output to drive the closing lid 10 to the closed state.

Then, at step 313, when it is confirmed that the closing lid 10 is completely closed based on the detection signal from the limit switch 12, at step 314, the drive signal to the opening / closing drive device 11 is stopped. The closing lid 10 is stopped in the closed state.

After that, in step 315, the descending container table 95b is moved to the lower position sensor 9 of the reversing loading device 95.
When it is confirmed that the detection signal has been turned ON by descending to the position 5c, the descending drive signal to the closing driving device 97 is stopped in step 316 to stop the descending, and the procedure returns to the first step.

When loading the processing carrier, the user touches the "start loading" button before starting the loading, whereby the processing medium is loaded from now on.
Let the 5 side recognize. Similarly, when the loading of the processing carrier is completed, the user touches the “end loading” button.

Returning to FIG. 17, when the user presses the “start loading” button in order to load the processing medium prior to the garbage processing, in step 403 the “loading end” button on the carrier has not been pressed, so the determination is not made. If the condition is not satisfied, the determination is similarly not satisfied in the following step 404, and it is determined whether or not the process has proceeded to step 405 and the “start loading” button has been pressed.
If this determination is satisfied, the routine goes to Step 406.

At step 406, the operator Ai is
At that time (before loading the processing medium), the measured value W of the load cell 50
Is replaced by the mass m (= 0) in the processing container based on At this time, since the operator Bi is in the initialized state Bi = 0, the determination at step 407 is satisfied, and the procedure returns to the first step.

Next, when the loading of the processing medium is completed and the user touches the "loading complete" button on the carrier loading screen of the touch panel 13C shown in FIG. 21, step 400 and step 402 in FIG. 17 are executed. Four
03, the reversal charging device 95 has not yet been moved up and down at this stage, so steps 403 and 404 are not satisfied, and the determination at step 405 is not satisfied either. Therefore, the process proceeds to step 408 and the “eject start” button is pressed. It is determined whether or not the determination is made, and this determination is not satisfied either, and the routine goes to Step 409. At step 409, “end”
It is determined whether or not the button has been pressed, and this determination is satisfied, and the routine goes to Step 410.

At step 410, the operator Bi is
The mass m in the processing container based on the measured value W of the load cell 50 after the processing medium is loaded (= mass of the loaded processing medium) is replaced. Then, in step 411, the increase / decrease amount C = Bi−Ai of the processing medium (in this case, it becomes equal to the mass of the input processing medium) is calculated, this value is recorded in the recorder 98, and Bi = 0 is set in step 412. And go back to the first step.

When the processing medium has been charged into the processing container 20 as described above, the user can move the raising button 1 of the operation panel operating section 13B as described above.
01 is operated and the garbage is thrown in by the reversal throwing device 95. Then, from the screen shown in FIG. 21 of the touch panel 13C, the "end input" button has already been pressed,
As described above, when the container table 95b of the reversal charging device 95 is raised to the position of the middle position sensor 95c, the determination at step 403 is satisfied through step 400 → step 402, and the routine proceeds to step 413. In step 413, the operator Ai is replaced with the mass m (= mass of the processing medium) in the processing container immediately before the garbage is loaded. After that, since Bi = 0 at this point, the determination at step 414 is satisfied, and the procedure returns to the first step.

When the input of the garbage is completed, the user operates the lower button 102 of the operation panel operation section 13B to operate the container table 95.
When "b" is lowered, since the "end loading" button has already been pressed on the screen of the touch panel 13C shown in FIG. 21, step 400 when the container base 95b has been lowered to the position of the middle position sensor 95c → Step 402
→ After step 403, the determination at step 404 is satisfied, and the routine goes to step 415.

At step 415, the operator Bi is replaced with the mass m (= processing medium + mass of food waste) in the processing container after the food waste is charged. Then, in step 416, the operator Li is replaced by Li + Bi-Ai (when the initial cumulative input amount Li = 0, the current input Bi-A
i is added to obtain a new cumulative input). Then, the value of this cumulative input amount is recorded in the recorder 98. The accumulated amount of garbage input at this time can be displayed on the touch panel 13C in real time through the touch panel display control unit 45Eb of the display control unit 45E, which will be described later.

Thereafter, in step 417, when the calculated cumulative input amount Li is divided into a predetermined period due to the capacity of the food waste disposer, no more than that within that period (in this example, one day, every day). A predetermined value (240 kg in this example; fixed value may be used,
For example, it may be appropriately set by the screen of the touch panel 13C). This 240
If the cumulative input value exceeds the kg, step 4
When the determination of 17 is satisfied, the process proceeds to step 418, and the touch panel 13C is operated via the touch panel display control unit 45Eb.
On the arbitrary screen of FIG. 22, a warning indicating that the input is excessive is displayed in the form of an interrupt window as shown in FIG. 22, for example. Then, the procedure returns to the first step in FIG.

In this way, when the garbage volume reduction processing is performed and the user tries to add additional garbage at some time, as in the case described above, step 400 → step 402 → step of FIG. After step 403, in step 413, the operator Ai measures the mass m (=
The mass of the processing medium + the mass of the garbage that has been reduced in volume), and at this point Bi is defined as the mass in the processing container at the time of the first charging (= the mass of the processing medium + the initial mass of the garbage before volume reduction). Therefore, the determination in step 414 is not satisfied, and
Move to 19.

At step 419, the operator Mi is changed to Mi.
+ Bi-Ai (initial cumulative weight loss Mi = 0
Then, Bi-Ai for the current weight loss is added to obtain a new cumulative weight loss). Then, the value of this cumulative weight reduction is recorded in the recorder 98.

As described above, the cumulative input amount of food waste and the cumulative reduction amount up to that time are obtained, and sequentially recorded by the recorder 98.
However, as one of the features of this embodiment,
The cumulative input amount and the cumulative reduction amount can be sequentially displayed on the touch panel in a daily report (weekly report) format every day, with 0:00 as a break.

That is, in FIG. 17, at midnight every day, the determination at step 402 is satisfied through step 400, and the routine proceeds to step 420. In step 420, the operator Ai is now (that is, immediately after midnight).
Is replaced with the mass m in the processing container (= mass of processing medium + mass of residual food waste).

Then, the process proceeds to step 421, at this point
The cumulative weight loss Mi that has already been calculated by (that is, immediately after midnight) is replaced with Mi + Bi-Ai (the cumulative weight loss Mi up to this point (from midnight on the previous day) from the time of the previous injection to this point Bi-Ai for the weight loss is added to obtain a new cumulative weight loss). Then, the value of the cumulative weight loss at midnight is recorded in the recorder 98.

Then, the process proceeds to step 422, and from the cumulative input amount Li up to this point (from midnight of the previous day) to the cumulative reduction amount Mi up to this point (from midnight of the previous day) obtained in step 421 above. Subtracting the value, the increase / decrease amount Ni within this predetermined period (24 hours in this example) is calculated and recorded in the recorder 98, and the cumulative input amount Li, cumulative decrease amount Mi, and increase / decrease amount Ni for the above day are calculated. Is displayed as a list via the touch panel display control unit 45Eb.

FIG. 23 shows the touch panel 1 as described above.
It is an example of a daily report screen displayed on 3C.
In this example, the screen immediately after midnight on October 27 is shown.

In FIG. 23, for example, in the column of Monday, October 21, as the processing results of this day, "cumulative input amount" (200 kg in this example) and "cumulative weight reduction" (in this example) of this day 190kg), "Decrease amount"
(10 kg in this example) are displayed side by side.
Hereinafter, the same display as Tuesday, October 22, Wednesday, October 23, ...

As for today (Sunday, October 27th), since the whole day has not yet passed, the columns of "cumulative reduction" and "increase / decrease" are blank. In the "Input amount" column, 1
The cumulative input amount up to this point, which is divided at midnight on October 27, is displayed in real time (see step 416 in FIG. 17 above). In addition, the "mass" column is
At this time, the processing container 2 based on the measured value of the load cell 50
The value itself of the mass M within 0 is displayed in real time (in this example, the total mass of the residual food waste + processing medium is 1840 kg). In the “mass” column before yesterday (Monday, October 21st to Saturday, October 26th), for example, the mass value immediately before midnight is displayed and held as the final value. .

The screen shown in FIG. 23 is displayed by touching the "daily report" button on the main menu screen shown in FIG. In addition, by touching the “previous week” button in the screen of FIG. 23, a list of data for the week (10 / 14-10 / 20) one week before the displayed week (10 / 21-10 / 27) is displayed. Is displayed.

Returning to FIG. 17, step 42 as described above.
When step 2 ends, the process moves to step 423, and the period identifier i
After adding 1 to, all the operators Ai, Li, Mi, and Ni are initialized to 0, and the operator Bi calculates the mass m in the processing container at this point (= processing medium mass) for the next calculation. Mass + mass of residual food waste).

By the way, as described above, the processing medium itself in the processing container 20 is exhausted as the garbage is sequentially added and the volume of the garbage is sequentially reduced while calculating and displaying the cumulative processing status every midnight. , The activity of the mixed microorganisms decreases, and the volume reduction treatment efficiency decreases. In such a case, the user replaces the processing medium as described above.

When the processing medium is to be discharged when the processing medium is replaced, the user touches the "carrier discharging" button on the carrier loading / unloading screen of the touch panel 13C shown in FIG. Move to the carrier discharge screen. This carrier discharge screen is provided with "discharge start" and "discharge end" buttons. When attempting to discharge the treated carrier, the user must "start discharge" before inputting and discharging.
By touching the button, the control device 45 side is made to recognize that the processing medium is to be discharged. Similarly, when the processing carrier has been charged, the user touches the “discharge end” button.

Returning to FIG. 17, when the user presses the "ejecting start" button as described above, the determination at step 408 is satisfied after going through step 400 → step 402 → step 403 → step 404 → step 405. Move to step 406.

In step 406, as described above, the operator Ai is replaced by the mass m in the processing container at this time (before the discharge of the processing medium) (= the mass of the old processing medium before the discharge).
At this time, the operator Bi is the most recent content substance amount measurement time.
Since it is the measured mass value (when the amount of substance changes or at midnight) and Bi ≠ 0, the determination at step 407 is not satisfied, and the routine proceeds to step 424.

At step 424, the cumulative reduction Mi that has been calculated up to this point (that is, immediately before the medium ejection) is reached.
Is replaced with Mi + Bi-Ai (cumulative weight loss Mi up to this point (from midnight of the previous day) to the new cumulative weight loss by adding the weight loss amount Bi-Ai from the Bi measurement timing to this point). The value of this cumulative weight loss is recorded by the recorder 98
Recorded in and return to the first step.

Next, when the discharge of the processing medium is completed and the user touches the "discharge completed" button on the carrier discharge screen of the touch panel 13C shown in FIG. 24, step 400 → step 402 → step 403 in FIG. →
After step 404 → step 405 → step 408, step 409 is not satisfied, the process proceeds to step 425, and it is determined whether or not the “end of discharge” button is pressed. If this determination is satisfied, the process proceeds to step 410.

In step 410, as described above, the operator Bi determines the mass m in the processing container after discharging the processing medium.
(= 0, or the mass of the carrier left). Then, in step 411, the increase / decrease amount C = B of the processing medium.
i-Ai (in this case, it becomes equal to the discharged old medium mass obtained in step 406) is calculated, this value is recorded in the recorder 98, and Bi = 0 is set in step 412 to return to the first procedure. .

As described above, according to the control procedure shown in FIG. 17, the mass measurement control unit 45D corrects the mass fluctuation due to the discharge / new input at the time of exchanging the processing medium, and sets the time as midnight. Cumulative amount of garbage L input on a daily basis
i, the amount of reduction Mi, and the amount of increase / decrease Ni are calculated every day, and are supplemented as new data at midnight, and the touch panel 1 as the daily report shown in FIG.
Display on 3C.

The mass measurement control unit 45D has a function of recording the amount of water sprayed at the time of water sprinkling described later, which will be described later.

Returning to FIG. 15, the target level setting section 45C.
Sets the target mass P according to the operation signal of the touch panel 13C of the operation panel 13 and the control signal from the mass measurement control unit 45D, and sets the value P to the main body stirring control unit 45Aa,
Exhaust fan control unit 45Ab, container heater control unit 45A
c, output to the main body sprinkling control unit 45Ad.

Now, the significance of the target mass P will be described.

Generally, the capacity of the garbage disposal to reduce the volume of garbage is not always constant, and particularly in the case of the so-called microbial type as in this embodiment, the environment in the processing container 20 is sufficient for microorganisms. It depends greatly on whether or not you are in a suitable environment that can be demonstrated. Humidity (moisture content), temperature, etc. are typical examples of the environmental factors, but the water content may vary greatly depending on the type of food waste to be put in. Therefore, for example, a food waste processor is provided with a water content sensor or the like for detecting the water content in the processing container 20, and the heater 56 and the water supply device are provided so that the detected water content value is maintained in a range suitable for microorganisms. It is conceivable to control 51, the exhaust fan 66 and the like.

However, the moisture content sensor currently available on the market at a relatively low cost may require a great amount of time, such as several tens of minutes to several hours, and its detection accuracy may be 10 times in some cases. In some cases, an error of about% may be included. Therefore, even if the feedback control of the water content sensor → heater heater 56 and the like is performed as described above, there is a possibility that the effectiveness of the control becomes poor in spite of the cost increase.

On the other hand, normally, the processing container 20 of the garbage processing machine.
The processing media to be housed and placed inside must be of a certain quality.
(That is, the water content is almost constant, for example, about 35%) is often used. Therefore, the mass of the processing medium housed and arranged in the processing container 20 is almost constant every time (for example, about 16).
00 kg), the water content of the treatment medium is known, and therefore the mass of the solid content and the mass of water in the treatment medium are generally known (the solid content of about 1040 k in the above example).
g, water content of about 560 kg).

In addition, the variation in the water content of the food waste volume-reduced by the food waste disposer is often within a certain range even if it is not so small depending on the user. Therefore, assuming that the mass of food waste to be treated is almost constant (eg, 200 kg) each time, the water content of the food waste is roughly assumed to be a certain value (eg, 75%), and the solid content of the food waste is The mass and the mass of water are generally known (in the above example, the solid content is about 50 kg and the water content is about 150 kg).

From the above, the total mass (1800 kg in the case of the above example, the same applies hereinafter) in the mixture of food waste and the treatment medium, the mass of the solid content (1090 kg) and the mass of the water (710 kg) are respectively Generally known. Therefore, when it is attempted to increase or decrease the water content of these mixtures in order to create a water content environment suitable for microorganisms, it is possible to calculate how much water should be increased or decreased for the known contents. For example, if the preferable moisture content of the microorganism is about 35%, the moisture content of the mixture in the above example is 710 / 1800≈39.4%, and therefore, about 4%.
It can be seen that it is sufficient to evaporate the water content of%.

Here, normally, when operating the garbage processing machine, it is uniquely determined how much the water content and the solid content are reduced. Therefore, the above 1800
It is possible to calculate how much of the mass of kg can be reduced as a whole at a total level to eventually evaporate about 4% of water. Moreover, in this type of food waste disposer, the means for measuring the mass M in the processing container 20 (the load cell 50 in this embodiment) is usually installed because of its property of reducing or eliminating the amount of food waste. Therefore, it is possible to easily and accurately calculate the mass in a short time. Further, even in the creation of an environment suitable for microorganisms, it is sufficient to manage only the mass, so that the user side is very easy and convenient.

From the above point of view, in the present embodiment, the target mass P in the volume reduction process is set, and each device is operated toward this target mass P to improve the water content for the microorganisms over time. It is a control that can create an environment.

The setting input of the target mass P is performed on the touch panel 13C provided on the operation panel 13.
That is, when the “automatic operation setting” button on the main menu screen shown in FIG. 19 is touch-operated, the screen shifts to the garbage disposal setting screen shown in FIG. 25. This garbage processing setting screen is provided with "0", "1", "2" ... "9" number buttons, a "confirm" button, and a "clear" button, and the "target level (target mass)" in the upper left corner. A new target mass can be entered as a number above the current target mass in the column. When the "Enter" button is touch-operated after finishing the input of numbers, as shown in FIG. 26, confirmation is required to set the input value as a new target mass value, and the "Yes" button is touch-operated here. As a result, this new input value is updated and set as a new target mass value.

The control procedure by the target level setting unit 45C will be described with reference to FIG. FIG. 27 is a flow chart showing the contents of control by the target level setting unit 45C of the control device 45 which constitutes an embodiment of the food waste processing machine of the present invention.

In FIG. 27, first, in step 600, the new target mass is touched from the touch panel 13C by the above operation.
It is determined whether (target level) is input. If the determination is satisfied, the process proceeds to step 601, and the new input value is reset as the new target mass P as described above.
(Fixed) and go back to the first step.

On the other hand, when there is no new target mass input,
The determination at step 600 is not satisfied, and the routine proceeds to step 602, where it is determined based on the signal from the above-mentioned mass measurement control unit 45D whether or not the amount of food waste input has been calculated.
If the determination is not satisfied, the procedure returns to step 600 and the same procedure is repeated. If the amount of raw garbage input is calculated,
Since there is a new input of food waste, in response to this, the process proceeds to step 603, and the current value of the target mass P is updated as P = P + 0.0675 (Bi-Ai).

The significance of this equation is as follows.

In other words, the amount of garbage input each time is shown in FIG.
It is represented by Bi-Ai as described using the flow shown in FIG. Here, in the present embodiment, the operation is performed with the goal of eliminating 95% of the garbage every time it is thrown in. Therefore, 5% will remain as a residue (solid content) in the processing container 20 every time, and the mass will be (Bi-Ai) * 0.05.

In the present embodiment, the operation is continued while allowing the remaining solid content residue (that is, the increase in mass due to the accumulation), but in order to maintain a preferable environment for the microorganisms, the water content of this residue is In the example, since it is equivalent to 35%, it is necessary to include the water content in the processing container 20 separately from the residue, and the mass thereof is (Bi-Ai) × 0.05 × 0.35. .

Therefore, the total of these (Bi-Ai) * 0.05 * 1.35 = (Bi-Ai) * 0.0675 should be accumulated in the target mass P each time garbage is added. Thus, it is possible to carry out an operation for creating an environment suitable for microorganisms aiming for a water content of 35% as a whole while allowing an increase in the residue mass of 5%.

Note that when the processing medium is introduced or discharged as described above with reference to FIGS. 20 to 24, the target mass P may need to be set again to a large value due to the mass variation of the processing medium. Therefore, when the "loading end" button is touched on the carrier loading screen of FIG. 21 or the "discharging end" button is touched on the carrier discharging screen of FIG. 24, as shown in FIGS. 28 and 29, respectively. As shown in the figure, an interruption window is displayed to prompt reconsideration regarding whether or not the target mass P needs to be reset.

Returning to FIG. 15, the main body stirring control unit 45Aa.
Is the time control signal from the timer 45g provided in the control device 45, the current measured mass M in the processing container 20 based on the detected value W in the load cell 50, and the target mass P from the target level setting unit 45C. And outputs a stirring command signal to the driving device 36 of the stirring device 30 according to
Is driven according to the stirring command signal, and thereby the stirring device 30 is rotationally driven.

The control procedure of the main body agitation control unit 45Aa will be described with reference to FIGS. 30 and 3
FIG. 1 is a flow chart showing the contents of control by the main body agitation control unit 45Aa of the control device 45 which constitutes an embodiment of the food waste processing machine of the present invention.

FIG. 30 shows the control procedure of the stirring operation of the normal volume reduction processing. First, at step 100, the flag F indicating the stirring operation state or the operation stop (stirring stop) state in the intermittent operation and the time calculation. Each child TN is initialized to 0.

After that, the routine proceeds to step 110, where the flag F
It is determined whether or not = 1. Initially, the flag F = 0, so the determination is not satisfied, and the routine goes to Step 120.
In step 120, a drive command signal is output to the stirring drive device 36 to cause the stirring device 30 to perform a stirring operation. The rotation speed of the stirring device 30 at this time is, for example, about 1 to 3 rpm.

Then, the routine proceeds to step 125, where it is judged whether or not the current mass M in the processing container 20 based on the detection value in the load cell 50 becomes less than or equal to the target mass P from the target level setting section 45C. If M> P, the determination is not satisfied, and the routine proceeds to step 130.

In step 130, it is determined whether the flag F = 2. If the flag F = 0, the determination is not satisfied, and the routine goes to Step 140. Step 1
At 40, after adding 1 to the time calculator TN, step 1
Move to 50.

In step 150, the time calculator TN sets a predetermined initial stirring time TNM0 (for example, 15).
Whether or not it is set and stored as a fixed value of about a minute, or is set and stored by a suitable external setting means, for example, may be set and stored as a fixed value each time the garbage volume reduction work is performed). If the time calculator TN ≦ TNM0, the determination is not satisfied and the routine returns to Step 120 and the above Steps 120 to 150 are repeated. If the time calculator TN> TNM0 is repeated by repeating this procedure, step 1
It is considered that the determination of 50 is satisfied and the initial stirring is sufficiently performed, and the process proceeds to step 160.

At step 160, the time calculator TN = 0
Clear and proceed to step 170, where flag F
Is set to F = 1 which represents the stirring stop state of the intermittent operation during the normal operation, and then the process returns to step 110.

In step 110, it is again determined whether or not the flag F = 1, but in step 170, the flag F =
Since it is 1, the determination is satisfied this time, and the routine proceeds to step 180.

In step 180, a stop command signal is output to the stirring drive device 36 to stop the stirring device 30. Then, in step 185, it is determined whether or not the current mass M has become equal to or less than the target mass P, as in step 125. If M> P, the determination is not satisfied, and the routine proceeds to step 190. In step 190, 1 is added to the time calculator TN, and then the process proceeds to step 200.

In step 200, the time calculator TN is set and stored as a predetermined intermittent stop time TNS which is set in advance (for example, as a fixed value of about 10 minutes, or by an appropriate external setting means, for example, the garbage volume reduction processing. It may be set and stored as a fixed value each time the work is performed). If the time calculator TN ≦ TNS, the determination is not satisfied and the routine returns to Step 180, and the above Step 1
Repeat steps 80-200. When this procedure is repeated and time calculator TN> TNS is satisfied, it is considered that the determination in step 200 is satisfied and the operation is stopped for a sufficient time, and the process proceeds to step 210.

In step 210, the time calculator TN = 0
Clear, and proceed to step 220, and flag F
Is set to F = 2, which represents the stirring operation state of the intermittent operation during the normal operation, and the process returns to step 110 again.

At step 110, the flag F is further returned again.
= 1 is determined, but the determination is not satisfied because the flag F = 2 in step 230 described above, and the process proceeds to step 120 again to stir the stirring device 30. Then, in step 130, it is determined again whether or not the flag F = 2, but this time, the determination is satisfied, and thus the process proceeds to step 230.

At step 230, the time calculator TN is set and stored as a predetermined intermittent stirring time TNM (for example, a fixed value of about 5 minutes), or an appropriate external setting means, for example, garbage volume reduction processing. It may be set and stored as a fixed value each time the work is performed). If the time calculator TN ≦ TNM, the determination is not satisfied and the routine returns to Step 120, and the above Step 12 is executed.
0, step 130, step 230, step 240
Repeat the procedure. By repeating this procedure, the time calculator T
When N> TNM, it is considered that the determination in step 240 is satisfied and stirring has been performed for a sufficient time, and the process proceeds to step 160. In step 160, the time calculator TN is cleared to 0, and the process proceeds to step 170 to set the flag F = 1,
It returns to step 110 again.

Since the flag F = 1 this time, step 110 is satisfied and the routine proceeds to step 180. The procedure of steps 180 to 220 when the flag F = 1 and the step 120 when the flag F = 2, Step 130,
The procedure of step 230, step 240, step 160, and step 170 is alternately repeated. That is, during normal operation, intermittent operation is performed in which the operation stopped state for the time TNS and the stirring operation state for the time TNM are alternately repeated.

As described above, the intermittent operation is performed,
When the volume of raw garbage is gradually reduced and the current mass M becomes less than or equal to the target mass P, step 125 or step 185
Is satisfied, the volume reduction process is not the purpose, and the minimum necessary operation control is aimed at ensuring the activity of microorganisms.

FIG. 31 shows the control procedure of this minimum stirring operation.

In FIG. 31, first in step 800,
The flag F and the time calculator TD during the minimum operation are initialized to 0, respectively.

After that, the routine proceeds to step 810, where the flag F
= 3 is determined. Initially, the flag F = 0, so the determination is not satisfied, and the routine goes to Step 820.
In step 820, a drive command signal is output to the stirring drive device 36 to cause the stirring device 30 to perform a stirring operation. The rotation speed of the stirring device 30 at this time is, for example, about 1 to 3 rpm.

Then, the process proceeds to step 825, where the current mass M in the processing container 20 is the target level setting section 45C.
From the target mass P is determined. M ≦
If P is maintained, the determination is satisfied, and the routine proceeds to step 830.

At step 830, 1 is added to the time calculator TD.
After adding, moves to step 840. Step 840
Then, the time calculator TD is set and stored as a fixed value of a predetermined intermittent stirring time TDM (for example, the same time as the above-described intermittent stirring time TNM, for example, about 5 minutes, or by an appropriate external setting means. For example, it may be set and stored as a fixed value each time the volume reduction work is performed). If the time calculator TD ≦ TDM, the determination is not satisfied and the routine returns to Step 820 and the above Steps 820 to 840 are repeated. When this procedure is repeated and the time calculator TD> TDM, it is considered that the determination in step 840 is satisfied and the stirring is performed for a sufficient time, and the process proceeds to step 850.

At step 850, the time calculator TD = 0
And then to step 860, the flag F
Represents the stirring stop state of intermittent operation during minimum operation F = 3
After that, the process returns to step 810.

In step 810, it is determined again whether or not the flag F = 3, but in step 860, the flag F =
Since it is 3, the determination is satisfied this time, and the routine goes to Step 870.

At step 870, a stop command signal is output to the stirring drive device 36 to stop the stirring device 30.

Then, the routine proceeds to step 875, where it is judged whether or not the present mass M is less than or equal to the target mass P. When M ≦ P is maintained, the determination is satisfied,
Go to step 880.

At step 880, 1 is added to the time calculator TD.
Then, the process moves to step 890.

In step 890, the time calculator TD causes the predetermined intermittent stop time TDS (a time longer than the intermittent stop time TNM in the normal operation described above, for example, 55).
Whether or not it is set and stored as a fixed value of about a minute, or is set and stored by a suitable external setting means, for example, may be set and stored as a fixed value each time the garbage volume reduction work is performed). If the time calculator TD ≦ TDS, the determination is not satisfied and the routine returns to Step 870 to repeat the above Steps 870-890. When this procedure is repeated and time calculator TD> TDS, step 890
Is judged to have been satisfied, and it is considered that the vehicle has stopped for a sufficient time, and the routine proceeds to step 900.

In step 900, the time calculator TD = 0
After clearing to step 910, the process proceeds to step 910, and the flag F is set to F = 4, which indicates the stirring operation state of the intermittent operation during the minimum operation.

Since the flag F = 4 this time, step 810 is not satisfied and the routine proceeds to step 820. The procedure of steps 820-860 when the flag F = 4 and steps 870-910 when the flag F = 3 are satisfied. Repeat steps 1 and 2 alternately. That is, at the time of minimum operation,
Intermittent operation is performed by alternately repeating the operation stop state of time TDS and the stirring operation state of time TDM.

As described above, the intermittent operation is performed,
If the target mass P is not modified, it continues as it is,
If the target mass P is corrected downward to a smaller value and the current mass becomes larger than the corrected target mass P, step 8
25 or the determination of step 875 is no longer satisfied, and the process returns to the normal operation control procedure for the purpose of volume reduction processing shown in the flow of FIG.

Returning to FIG. 15, the exhaust fan control unit 45Ab.
Is the processing container 2 detected by the temperature sensor 21a for the processing medium.
According to the temperature tm of the processing medium in 0, the current measured mass M in the processing container 20 based on the detected value in the load cell 50, and the target mass P from the target level setting unit 45C, the fan drive device 68 is controlled. Outputs a drive command signal. Although not shown, the drive device 68 of the exhaust fan 66 may be controlled according to the detection signal of the air flow meter 19a provided in the intake conduit 18.

A control procedure by the exhaust fan control unit 45Ab will be described with reference to FIG. FIG. 32 is a flowchart showing the contents of control by the exhaust fan control unit 45Ab of the control device 45 which constitutes an embodiment of the food waste processing machine of the present invention.

Referring to FIG. 32, first in step 500,
It is determined whether or not the temperature tm of the processing medium is 30 ° C. or higher. If the temperature tm of the processing medium is 30 ° C. or higher, the determination at step 500 is satisfied, and the routine proceeds to step 505, where the current mass M in the processing container 20 becomes equal to or lower than the target mass P from the target level setting unit 45C. Determine whether If M> P, the determination is not satisfied, and the routine proceeds to step 510. In step 510, a drive command signal for medium speed rotation (for example, 25 Hz) is output to the fan drive device 68 via the inverter 68A, and the procedure returns to the first step.

On the other hand, when the temperature tm of the processing medium is less than 30 ° C. in step 500, the determination is not satisfied, and the routine goes to step 520. In step 520, a drive command signal for low speed rotation (for example, 10 Hz) is sent to the inverter 68A.

As described above, the exhaust fan control section 45
When the temperature tm of the processing medium in the processing container 20 becomes equal to or higher than the set temperature of 30 ° C., the Ab switches from the normal low speed rotation to the medium speed rotation drive command signal to change the exhaust (intake) air volume of the exhaust fan 66. I have a lot.

However, when the volume of raw garbage is gradually reduced and the current mass M becomes less than or equal to the target mass P, tm ≧
Even if the temperature reaches 30 ° C., the determination in step 505 is satisfied, and the exhaust fan 66 shifts to a low speed rotation (for example, 10 Hz) which is the minimum necessary operation control for the purpose of ensuring the activity of microorganisms, not for the purpose of volume reduction processing. However, the target mass P is corrected downward to a smaller value and the current mass is changed to the corrected target mass P.
If it becomes larger than the above, the determination in step 505 is no longer satisfied, so the process returns to the original normal operation control procedure for the purpose of volume reduction processing again.

Returning to FIG. 15, the container heater controller 45Ac
Is the processing container 2 detected by the temperature sensor 21a for the processing medium.
The temperature tm of the processing medium within 0 and the heater temperature sensor 2
The temperature th of the heater 56 detected in 1c, the current measured mass M in the processing container 20 based on the detected value W in the load cell 50, and the target mass P from the target level setting unit 45C are used for heating. A heating command signal is output to the heater 56.

The control procedure by this container heater control unit 45Ac will be described with reference to FIG. FIG. 33 is a flowchart showing the contents of control by the container heater control unit 45Ac of the control device 45 which constitutes an embodiment of the food waste disposer of the present invention.

In FIG. 33, first in step 700,
It is determined whether or not the current mass M in the processing container 20 detected by the load cell 50 is less than or equal to the target mass P from the target level setting unit 45C. If M> P, the determination is not satisfied, and the routine proceeds to step 710.

Thereafter, in step 710, it is determined whether or not the temperature tm of the processing medium is equal to or higher than the set temperature 35 ° C. If the temperature tm of the processing medium is lower than 35 ° C., the determination is not satisfied, and the routine goes to Step 720. At step 720, the temperature th of the heater 56 is set to the allowable set temperature of 100 ° C.
It is determined whether or not the above. When the temperature th of the heater 56 is lower than 100 ° C., the determination at step 720 is not satisfied, and the routine proceeds to step 730, where a heating command signal is output to the heater 56 for heating.

If the temperature tm of the processing medium is 35 ° C. or higher in step 710, or if the temperature th of the heater 56 is 100 ° C. or higher in step 720, each determination is satisfied, Move to step 740. In step 740, a stop command signal is output to the heater 56 to stop heating.

When step 730 or step 740 is completed, the procedure returns to step 700 and the same procedure is repeated.

As described above, the container heater control section 45
Ac has a temperature tm of the processing medium in the processing container 20 of 35 ° C.
Or more, or the temperature th of the heater 56 is 1
The heater 56 is stopped when the temperature exceeds 00 ° C.

However, when the volume of raw garbage is gradually reduced and the current mass M becomes equal to or less than the target mass P, the process proceeds to step 750, and when tm ≧ 25 ° C., the determination of step 750 is satisfied. As a result, the heater 5
No. 6 does not aim at volume reduction treatment but shifts to the necessary minimum operation control for the purpose of securing the activity of microorganisms, and the temperature tm of the treatment medium in the treatment container 20 becomes 25 ° C. or higher, or the heater 5
When the temperature th of 6 becomes 100 ° C. or more, the heater 56
Will be the control to stop. However, if the target mass P is corrected downward to a smaller value and the current mass becomes larger than the corrected target mass P, the determination in step 700 will not be satisfied, so that the volume reduction process is performed again. Return to the normal operation control procedure of.

Returning to FIG. 15, the main unit sprinkling control unit 45Ad.
Is the mass M in the processing container based on the detection value W of the load cell 50, the flow rate detection signal from the flow meter 55, and the charging control unit 4.
Based on the control signal from 5B, the control signal from the mass measurement control unit 45D, and the target mass P from the target level setting unit 45C, it is determined that the water content of the food waste and the processing medium is below the appropriate range. In this case, a command signal is output to the electromagnetic valve 54 of the water supply device 51 so that the electromagnetic valve 54 opens, and water is supplied from the water supply device 51 into the processing container 20. When it is determined that the water content of the food waste and the treatment medium is within the proper range (or returned), a command signal for closing the electromagnetic valve 54 of the water supply device 51 is output to cut off the water. This controls the water content of the food waste and the treatment medium within an appropriate range.

FIG. 34 is a main body sprinkling control section 4 of a control device 45 which constitutes an embodiment of the garbage disposal of the present invention.
It is a flow chart showing an actual concrete control procedure for making the above-mentioned water content into an appropriate range by 5Ad.

In FIG. 34, first, in step 1000, the mass m in the processing container based on the detected value W of the load cell is measured.
Is equal to or less than the sprinkling reference target mass (= P-50) obtained by subtracting 50 kg from the target mass P.
(Note that this 50 kg is a fixed value and is set in advance by the controller 45.
It may be set and stored in the interior, or may be set and stored by an appropriate external setting means, for example, every time the garbage volume reduction work is performed). As described above in the explanation of the meaning of the target mass P, this embodiment basically manages the appropriate range of the water content by replacing it with the mass, and when the target mass P is reduced by 50 kg or more. However, it is considered that the water content has become too low due to excessive evaporation of water (requires water supply). Therefore, if this determination is not satisfied, it is considered that there is no need for water supply, and the process moves to step 1010 and a command signal is output to close the electromagnetic valve 54 of the water supply device 51.

On the other hand, when the determination at step 1000 is satisfied, the routine goes to step 1020. In step 1020, the flow meter 5 is reset after the value of the water spray amount is reset to the initial value 0.
The flow rate detection signal from 5 is input to start the sprinkling amount measurement.

After that, the routine proceeds to step 1030, and it is judged based on the control signal from the closing controller 45B whether or not the reversing closing device 95 is currently performing the closing operation of the container 96. Specifically, for example, when the raising switch 101 of the operation panel 13 is pressed, step 3 of the flow shown in FIG.

10, the solenoid valve 54 is closed. If the determination is not satisfied, the process moves to step 1035.

At step 1035, the mass measurement controller 4
Based on the control signal from 5D, it is determined whether or not the processing medium is currently being discharged or loaded. Specifically, for example, one of the steps 405, 406, 407, and 424 in the flow shown in FIG. 17 is being executed due to the touch operation of the “carrier input start” button or the “carrier output start” button on the touch panel 13C. It may be determined whether or not If the judgment is satisfied, step 1
Moving to 010, the solenoid valve 54 is closed. If the determination is not satisfied, the process moves to step 1040.

At step 1040, a command signal is output to the electromagnetic valve 54 of the water supply device 51 so as to open it, and water supply (sprinkling) is started. Then, the process proceeds to step 1050.

In step 1050, it is determined based on the detection signal of the flowmeter 55 whether the sprinkling amount is 50 liters or more (in other words, 50 liters of water has been supplied). If 50 liters have not yet been supplied, the determination is not satisfied and the routine returns to step 1030, and the same procedure is repeated until the volume reaches 50 liters.

After the supply of 50 liters is over, step 1
When the determination of 050 is satisfied, the process proceeds to step 1010 and the solenoid valve 54 is closed.

The deodorizing / sprinkling control unit 45Ae is a controller 45.
In response to a time control signal from the timer 45g provided in (in other words, at a time interval such that the water content of the deodorizing medium in the deodorizing tank 70 is within an appropriate range), a watering command signal is sent to the solenoid valve 84 of the water supply device 80. (Open / close signal) is output.

That is, for the stirring means control, step 825 or step 875 in FIG. 31 is no longer satisfied, and the flow returns to the flow of FIG. 30, and for fan control, the control is based on step 510, step 520, and step 530 in FIG. Regarding heater control, step 710 and step 72 in FIG.
The control is based on 0, step 730, and step 740. After restarting the normal volume reduction operation in this way,
The food waste processing machine continues the volume reduction processing operation until the amount M of the substance contained in the processing container becomes equal to or lower than the target mass P corrected downward. Therefore, the water content environment can be gradually improved in a favorable direction for the microorganisms.

On the other hand, at the time of checking the inside of the processing container 20 described above, if it is determined that the water content in the processing container 20 is lower than the expected state, the user touches the touch panel 13C. Then, the first target mass P is again set to a large value (upward correction) again from the main menu screen of FIG. 19 → the food waste setting screen of FIG. 25. As a result, when the volume of garbage is reduced after the next time,
After that, the food waste disposer performs the volume reduction operation until the corrected first target mass P or less, so if the food waste has the same properties, the water content environment can be made better for the microorganisms than the previous time. it can. At this time, the water content environment can be improved more quickly and reliably by touching the main body "watering" on the touch panel screen shown in FIG.

As described above, in the food waste disposer of the present embodiment, the variation in the water content of the input food waste can be dealt with finely by a simple operation of correcting and inputting the target mass P on the touch panel 13C. , The water content can be sequentially controlled to the suitable environment side of the microorganism. Therefore, it is possible to surely reduce the volume of raw garbage day by day in response to the recent needs.

In addition, in the food waste disposer of this embodiment, when the volume is reduced to the target mass P, the stirring device 3 is immediately used.
0, the exhaust fan 66, and the heater 56 are not stopped, but by performing the minimum required operation as described above, it is possible to secure the minimum required oxygen supply to the microorganisms, and some of the microorganisms are It can be prevented from dying or losing its activity. In particular, when the above minimum required operation is performed, if the current mass M further decreases due to, for example, the state being prolonged, and the water spraying reference target mass (= P-50) or less, the main body watering control FIG. 34 performed by the section 45Ad
Step 1000 in the flow of 1 is satisfied, and automatic water supply of 50 liters is performed in Steps 1024 to 1050. As a result, it is possible to reliably prevent some of the above-mentioned microorganisms from being killed or the activity being reduced.

At this time, by switching to the minimum operation when the target mass P or less is reached as described above, there is an effect that the running cost can be suppressed as compared with the normal operation. Further, it also has an effect of suppressing drying of the processing medium and suppressing clogging of the filters 64 and 65 in the deodorization tank 70 due to dust.

Furthermore, the target mass (first target mass) P for switching the target mass to the minimum operation, and a target mass smaller than this (second target mass; sprinkling reference target mass in this example)
Setting the two values of P-50 kg has the following significance.

As described above, as in this embodiment,
When the water content of the food waste to be actually input is roughly regarded as a certain value and is managed by the total mass of the processing container 20, and when the operation is performed toward a certain target mass, when the volume reduction process is completed up to the target mass Then, the inside of the processing container 20 may be dry or moist.

In this case, in order to correct the target mass and restore the inside of the processing container 20 to a good state as described above, it is easier to dry. The reason is that when the mixture of food waste, which usually contains starch, and the treatment medium has a high water content, it becomes hard to supply oxygen to the microorganisms by solidifying into a dumpling, which results in returning to a favorable environment. Because it will be difficult.

From the above point of view, in the present embodiment, first, the first target mass P is set corresponding to the average water content of raw garbage, and the normal volume reduction operation is performed up to this target mass P.
The second target mass P-50 kg is set correspondingly to the garbage having a high water content which may be thrown in, and after the current mass M reaches the first target mass P, the second target mass P-50 is set. The inside of the processing container 20 is gradually dried with a minimum operation up to.

By doing so, when the average amount of water content is added to the garbage, a favorable moisture content environment is achieved when the first target mass is reached, and when the second target mass is reached, it becomes slightly dry; When a large amount of raw garbage is introduced, it is still moist when the first target mass is reached, but when the second target mass is reached, a good moisture content environment is achieved; when a small amount of raw garbage is introduced, when the first target mass is reached It becomes dry and the second
When the target mass is reached, it will be a little too dry. That is, it is possible to prevent at least the treatment medium from being kept wet regardless of the water content of the garbage.

At this time, since the minimum operation is performed after the first target mass is reached, even in the above case, it is possible to take a long time from the arrival of the first target mass to the second target mass (drying). it can. Therefore, it is possible to lengthen the cycle of the work for confirming the inside of the processing container 20 which is required by the user.

In the above, when checking the inside of the processing container 20, the automatic operation mode is once terminated and the closing lid 10 is opened and closed manually, but the present invention is not limited to this. That is, the automatic operation itself continues in the automatic operation mode, and the inside of the processing container 20 can be checked by manually (or automatically) only opening / closing the closing lid 10 in the form of interrupt control processing. You may do it.

[0249]

According to the present invention, the water content is controlled in accordance with the variation of the water content of the input garbage by the user's simple operation only by the simple operation of correcting and inputting the first target mass. Yes, you can reliably reduce the volume of food waste day by day.
