As a result, it is possible to prevent reverse flow of water and garbage from the storage tank to the crusher, outflow of water and garbage from the disposer to the outside, and the like. In addition, it is not necessary for the operator to constantly monitor the disposer and manually switch execution / stop of the water supply to the disposer, so that the convenience of the operator can be improved.

  In the case of the disposer of the present invention, the execution / stop of water supply is switched using a valve and a water level detection switch that switches between opening and closing of the valve, and therefore, the execution / stop of water supply can be automatically switched with a simple configuration.

  In the case of the disposer and the garbage disposal system according to the present invention, when an instruction for prohibiting the conveyance of garbage is given, the water supply to the disposer is stopped. In addition, excessive water supply to the disposer can be reliably prevented. Here, since the crusher and the conveying means are stopped, there is no problem even if the water supply to the crusher and the storage tank is stopped.

  In the case of the disposer and the garbage disposal system of the present invention, it is determined whether or not the garbage disposal apparatus has excessive water supply according to the level of the water level in the disposer storage tank, and if the water supply is excessive, water is supplied to the disposer. Since it can be stopped, excessive water supply to the disposer can be prevented. In such a case, the timing for stopping the water supply to the disposer can be changed according to the situation on the side of the garbage disposal device (for example, the water level of the aquarium), and the garbage disposal system can be operated more flexibly. .

  Hereinafter, the present invention will be described in detail with reference to the drawings illustrating embodiments thereof.

Embodiment 1.
FIG. 1 is a front view showing a configuration of a garbage disposal system 3 according to Embodiment 1 of the present invention. The garbage disposal system 3 is a commercial garbage disposal system, and includes a disposer 1 and a wet garbage disposal apparatus 2 installed on the ground.
The disposer 1 includes a crushing chamber 140 for crushing garbage, and a storage tank 11 for temporarily storing the crushed garbage before being transported to the treatment tank 21 provided in the garbage processing apparatus 2. A water supply unit 10 serving as a water supply means for supplying water to the disposer 1 and more specifically to the storage tank 11 and a crusher 14 (FIG. 2), which will be described later, is arranged above the storage tank 11 and the crushing chamber 140. It becomes.

  FIG. 2 is a schematic perspective front view showing the configuration of the disposer 1, and FIG. 3 is a circuit diagram showing a circuit arrangement for operating the disposer 1. FIG. 4 is a block diagram showing the configuration of the operation panel 22 of the garbage processing apparatus 2.

  As shown in FIG. 2, the crushing chamber 140 of the disposer 1 has a built-in crusher 14 including a cutter unit (not shown) that crushes raw garbage and a motor 14m that drives the cutter unit. Garbage is thrown into the crusher 14 from the inlet 141 at the top of the crushing chamber 140 and tap water supplied from the water supply unit 10 to the inlet 141. The thrown garbage is less than about 5 mm square by the crusher 14. It is crushed to the size. The crushed raw garbage flows into the storage tank 11 together with tap water through a connecting pipe 142 that connects the crusher 14 and the storage tank 11. The end of the connection pipe 142 on the storage tank 11 side is arranged at the center in the height direction of the storage tank 11.

The storage tank 11 stores raw garbage and tap water crushed by the crusher 14.
Moreover, an underwater pump is used as a conveying means for conveying the garbage and tap water stored in the storage tank 11 to the outside of the disposer 1 (specifically, the treatment tank 21 of the garbage processing apparatus 2 shown in FIG. 1). A transfer pump 17 is erected on the bottom surface of the storage tank 11. A plurality of legs are provided on the bottom surface of the transfer pump 17, and the bottom surface of the transfer pump 17 and the bottom surface of the storage tank 11 are separated by an appropriate length. In addition, a suction port is opened on the bottom surface of the transport pump 17.

The transport pump 17 starts to operate when the water level of the storage tank 11 is equal to or higher than the first predetermined water level W ₁ , and tap water stored in the storage tank 11 and raw garbage contained in the tap water are supplied from the suction port. Inhaled and discharged to the outside of the disposer 1 via the discharge pipe 171. Further, the transport pump 17 is configured to be deactivated when the water level of the storage tank 11 becomes equal to or lower than the second predetermined water level W ₂ lower than the first predetermined water level W ₁ .
Such an operation start / stop of the transport pump 17 is executed using float switches (not shown) arranged at the first predetermined water level W ₁ and the second predetermined water level W _{2, respectively} .

The first predetermined water level W ₁ is set at a position lower by an appropriate distance than the height of the end of the connection pipe 142 on the storage tank 11 side. For this reason, the tap water and garbage which are stored in the storage tank 11 are prevented from flowing back to the crusher 14 side via the connecting pipe 142. The second predetermined water level W ₂ is set at a position higher than the suction port of the transport pump 17 by an appropriate distance. For this reason, idling of the transport pump 17 is prevented.

The water supply unit 10 includes a water tap 100, water pipes 101, 102, 103 and a three-way valve 104.
The water pipes 102 and 103 are connected to the lid of the inlet 141 and the upper surface of the storage tank 11, and a plurality of small holes are formed at the ends of the crusher 14 side and the storage tank 11 side to supply water. Tap water is discharged in the form of a shower. The water pipes 102 and 103 are connected to the water pipe 101 via the three-way valve 104, and the water pipe 101 is connected to the water supply via the electromagnetic valve 12 and the water tap 100.

The faucet 100 is made of a faucet, for example, and is opened and closed by an operator, but is normally open. When the water tap 100 is in the closed state, the tap water is not supplied to the disposer 1 regardless of whether the solenoid valve 12 is opened or closed.
The solenoid valve 12 is configured to be in an open state / closed state by energizing / stopping the solenoid valve 12. An electric valve may be used instead of the electromagnetic valve 12.
When the solenoid valve 12 is in the closed state, the tap water is not supplied to the disposer 1 even if the water tap 100 is in the open state.

  When both the solenoid valve 12 and the water tap 100 are open, tap water passes through the water pipe 101, the three-way valve 104, and the water pipe 102 in this order, and is supplied to the crusher 14 from the inlet 141. The tap water supplied to the crusher 14 passes through the connecting pipe 142 and flows into the storage tank 11 together with the raw garbage crushed by the crusher 14. Similarly, when both the solenoid valve 12 and the water tap 100 are in an open state, tap water passes through the water pipe 101, the three-way valve 104 and the water pipe 103 in this order, and is supplied to the storage tank 11.

Such solenoid valve 12, after starting the operation of the transport pump 17 by the operation of the float switch corresponding to the first predetermined water level W _1, if the float switch corresponding to the second predetermined water level W ₂ is operated, i.e., garbage and Even when the conveyance of tap water is completed, the water supply to the disposer 1 is continued regardless of the operation stop of the conveyance pump 17.

Here, the tap water supplied to the crusher 14 moves smoothly into the crusher 14 from the input port 141, and the crushed garbage passes through the connecting pipe 142 and is stored in the storage tank 11. Used to smoothly flow into The tap water is used for cleaning the inlet 141, the crusher 14, and the connecting pipe 142.
The tap water supplied to the storage tank 11 is used for cooling the transfer pump 17, removing garbage attached to the float switch and an overflow switch 13 described later, cleaning the inside of the storage tank 11, and the like.

  In other words, the supply of water from the water supply unit 10 to the disposer 1 suppresses garbage, sewage, and the like from remaining in the crushing chamber 140 and the storage tank 11, thereby suppressing the generation of bad odors and breeding of pests and bacteria. Can be suppressed and is hygienic. Further, malfunction of the float switch and the overflow switch 13 due to the attachment of garbage is prevented.

  When the transport pump 17 is stopped due to a failure or when the transport pump 17 is stopped from the garbage processing apparatus 2 side as will be described later, the tap water is supplied to the storage tank 11 even after the transport pump 17 is stopped. Is supplied via the water pipe 103 and / or the connecting pipe 142, the water supply to the storage tank 11 becomes excessive, and the tap water and garbage stored in the storage tank 11 pass through the connecting pipe 142. Then, it may flow backward to the crusher 14 side and further flow out (overflow) from the input port 141 to the outside of the disposer 1.

  Similarly, when the amount of water supplied to the storage tank 11 is larger than the amount of suction of the transport pump 17 (for example, when the amount of water supplied from the water supply unit 10 is excessive, or when the suction port of the transport pump 17 is half of garbage) In the case where clogging is difficult, the water supply to the storage tank 11 becomes excessive.

To prevent excessive supply of water to the reservoir 11, in this embodiment, the first higher than a predetermined water level W _1, as appropriate distance position lower than the height of the end portion of the reservoir 11 side of the connecting pipe 142 to set the overflow water level W _0, in the overflow water level W _0, to place the overflow switch 13 made using a float switch as the water level detection switch.

Overflow switch 13 has a浮玉floating on the water surface of the tap water contained in the reservoir 11, when the vertical position of the浮玉is below the overflow water level W ₀ is turned on, the overflow water level W ₀ When it is above, it is turned off.
Such an overflow switch 13 and the solenoid valve 12 are connected in series as shown in FIG. 3, and when the overflow switch 13 is in an ON state, the solenoid valve 12 is energized and opened. Water supply to the disposer 1 is executed.
On the other hand, when the overflow switch 13 is in the off state, the solenoid valve 12 is not energized and is in the closed state.

  The electromagnetic valve 12, the motor 14m of the crusher 14, and the transport pump 17 are connected to the commercial power source S via the breaker B and are supplied with power from the commercial power source S. In addition, various lamps 161, 162, and 163, which will be described later, are also connected to the commercial power source S via a breaker B so that power is supplied from the commercial power source S.

The operation unit 16 includes a power lamp 161, an operation lamp 162, a standby lamp 163, an operation button 164, a stop button 165, and an emergency stop button 166.

  Further, the operation notification unit 150 and the operation permission unit 15 of the disposer 1 shown in FIG. 3 are each connected to the operation panel 22 of the garbage processing apparatus 2 using a relay. The driving notification unit 150 outputs an operation signal indicating that the motor 14m is in operation to the operation panel 22 when in the on state, and does not output the operation signal when in the off state. On the other hand, the driving permission unit 15 is turned on when a permission signal, which will be described later, is input from the operation panel 22, and is turned off when it is not input.

  The emergency stop button 166 and the operation permission unit 15 are provided for the operation lamp 162, the standby lamp 163, the electromagnetic valve 12, the motor 14m, the transfer pump 17, and the operation notification unit 150. When the operation permission unit 15 is in the ON state and the emergency stop button 166 is not operated, power can be supplied to each unit, the standby lamp 163 is lit, the operation lamp 162 is lit, and the solenoid valve 12 Can be opened, the motor 14m and the transport pump 17 can be operated, and the operation notification unit 150 can be turned on.

  When the emergency stop button 166 is operated, or when the operation permission unit 15 is in the OFF state, the operation lamp 162 and the standby lamp 163 are turned off, the solenoid valve 12 is closed, and the motor 14m and the transport pump 17 are deactivated. Then, the driving notification unit 150 is turned off.

That is, the standby lamp 163 informs the operator that the operation of the disposer 1 is possible (permitted) / impossible (prohibited) by turning on / off.
The power lamp 161 is provided for the commercial power source S and is turned on / off when the power source of the disposer 1 is in the on / off state. That is, the power lamp 161 notifies the operator of whether the disposer 1 is turned on or off.

The operation button 164 and the stop button 165 are provided for the operation lamp 162, the motor 14m, and the operation notification unit 150.
The operation button 164 is an operation button for operating the crusher 14, and when operated while the standby lamp 163 is lit, the motor 14m starts operating, the operation lamp 162 is lit, and the operation notification unit 150 is turned on. Become. When the operation button 164 is operated while the standby lamp 163 is turned off, the crusher 14 remains stopped, the operation lamp 162 remains turned off, and the operation notification unit 150 remains off.

The stop button 165 is an operation button for stopping the crusher 14, and when operated while the operation lamp 162 is lit, the motor 14m is deactivated, the operation lamp 162 is turned off, and the operation notification unit 150 is turned off. Become.
In other words, the operation lamp 162 informs the operator of the operation / stop of the motor 14m and eventually the crusher 14 by turning on / off.

  When each of the driving notification unit 150 and the driving permission unit 15 is in the on state, when the driving permission unit 15 is in the off state, the driving notification unit 150 is also in the off state. However, when each of the driving notification unit 150 and the driving permission unit 15 is in the off state, when the driving permission unit 15 is in the on state, the driving notification unit 150 remains in the off state, and the driving button 164 is in this state. Is operated, the driving notification unit 150 is also turned on.

  Now, the processing tank 21 of the garbage processing apparatus 2 is a water tank for storing water mixed with microorganisms (processed water). As shown in FIGS. 1 and 2, the processing tank 21 and the storage tank for the disposer 1 are used. 11 are connected to each other through a conveyance pipe 30. The end of the transport pipe 30 on the disposer 1 side is connected to the discharge pipe 171 of the transport pump 17 via a check valve 31 that prevents the tap water containing crushed garbage from flowing back to the transport pump 17 side. The end of the transport pipe 30 on the side of the garbage processing apparatus 2 is connected to the upper part of the side surface of the processing tank 21.

Further, an operation panel 22 for operating the garbage processing apparatus 2 is installed above the processing tank 21.
As shown in FIG. 4, the operation panel 22 includes a CPU 20, a ROM 25, a RAM 26, a timer 27, an operation unit 28, and an I / F (interface) unit 29 that are electrically connected to each other via a bus or a signal line. . In addition, the operation panel 22 is connected to the function unit of the garbage processing apparatus 2 (parts such as pumps for water supply and agitation, valves for water supply and air supply, etc.) 23 and water level detection via the I / F unit 29. Each of the units 24 is connected to the operation notification unit 150 and the operation permission unit 15 of the disposer 1 through the I / F unit 29.

  The water level detection unit 24 uses a float switch and is provided inside the processing tank 21. The water level detection unit 24 has a floating ball floating on the surface of the processing water in the processing tank 21, and the vertical position of the floating ball indicates the overflow water level of the processing tank 21 (for example, the height of the drain outlet of the processing tank 21). This is an overflow switch that outputs a water level excess signal to the operation panel 22 when it exceeds.

The CPU 20 of the operation panel 22 uses the RAM 26 as a work area, and outputs a control signal for controlling the functional unit 23 to the functional unit 23 of the garbage processing apparatus 2 according to the control program and data stored in the ROM 25.
Further, the CPU 20 receives the water level excess signal output from the water level detection unit 24 and the operation signal output from the operation notification unit 150.

  The CPU 20 starts to output a control signal for controlling the function unit 23 in accordance with the elapsed time measured by the timer 27, the operation input by the operator using the operation unit 28, the input of the water level excess signal from the water level detection unit 24, and the like. / Stops output. For example, when a predetermined time has elapsed since the operation signal was input, the CPU 20 determines that the garbage has been conveyed from the disposer 1 and agitates the treated water in the treatment tank 21 to start the treatment of the garbage. A control signal for operating the pump is output. Moreover, CPU20 outputs the control signal which closes the valve | bulb which supplies water to the processing tank 21, when a water level excess signal is input, and prevents the excessive water supply to the processing tank 21. FIG.

When the water level excess signal is not input from the water level detection unit 24, the CPU 20 outputs a permission signal to the operation permission unit 15 because the processing tank 21 has not overflowed. The output of the permission signal (ON state permission signal) is an instruction to permit the conveyance of the garbage to the treatment tank 21 of the garbage processing apparatus 2.
Further, when the water level excess signal is input from the water level detection unit 24, the CPU 20 stops outputting the permission signal to the operation permission unit 15. The output stop of the permission signal (off-state permission signal) is an instruction to prohibit the conveyance of the garbage to the treatment tank 21 of the garbage processing apparatus 2.

  In other words, when transporting garbage from the disposer 1 to the garbage processing apparatus 2 is permitted, the electromagnetic valve 12 is opened, and water can be supplied to the crusher 14 and the storage tank 11. Garbage can be crushed, and the garbage and tap water stored in the storage tank 11 can be transported to the treatment tank 21 by the transport pump 17.

  On the other hand, when the transport of garbage from the disposer 1 to the garbage disposal apparatus 2 is prohibited, the electromagnetic valve 12 is closed and tap water is not supplied to the crusher 14 and the storage tank 11, and the crusher 14 The garbage is not crushed, and the garbage and tap water stored in the storage tank 11 by the transport pump 17 are not transported to the treatment tank 21 of the garbage processing apparatus 2.

  When the garbage disposal system 3 as described above is used, when the garbage is thrown into the inlet 141, the operator checks the lighting of the standby lamp 163 and then operates the operation button 164 to operate the crusher 14. After starting operation and throwing in garbage, the stop button 165 is operated and the crusher 14 is stopped.

However, when the standby lamp 163 is turned off, troubles such as the garbage processing apparatus 2 not being turned on and the processing tank 21 overflowing have occurred. Execute the garbage disposal.
Further, the amount of water supplied from the water supply unit 10 to the disposer 1 per unit time needs to be smaller than the amount of suction per unit time of the transport pump 17.

When garbage is input from the inlet 141 and tap water is supplied from the water pipe 102 to the inlet 141, the input garbage is crushed by the crusher 14, and the crushed garbage and the inlet 141 are supplied. The supplied tap water flows into the storage tank 11 via the connecting pipe 142 and is stored in the storage tank 11 until the water level of the storage tank 11 reaches the first predetermined water level W ₁ .

When garbage and tap water flow into the storage tank 11 from the crushing chamber 140 and further tap water is supplied from the water pipe 103 to the storage tank 11, the water level in the storage tank 11 rises. When the water level of the storage tank 11 becomes equal to or higher than the first predetermined water level W ₁ , that is, when appropriate amounts of garbage and tap water are stored in the storage tank 11, the transfer pump 17 starts to operate, and the storage tank 11 is sucked from the suction port of the transport pump 17, passes through the discharge pipe 171, the check valve 31 and the transport pipe 30, and is continuously discharged into the treatment tank 21.
Further, when the water level of the storage tank 11 becomes equal to or lower than the second predetermined water level W ₂ , that is, when the garbage and tap water in the storage tank 11 have been transferred to the treatment tank 21, the transfer pump 17 stops operating.

As described above, the disposer 1 conveys the crushed garbage to the processing tank 21 of the garbage processing apparatus 2.
In the treatment tank 21, the garbage and tap water conveyed from the disposer 1 are mixed with the treated water, and the garbage is decomposed by microorganisms contained in the treated water.

In addition, when overflow occurs in the storage tank 11, the solenoid valve 12 is closed by the overflow switch 13, so that water supply from the water pipes 102 and 103 to the storage tank 11 and the crusher 14 is stopped. Excess water supply to the tank 11 is prevented.
After the water supply is stopped, when the transport pump 17 continues to operate and the overflow is resolved, the solenoid valve 12 is opened by the overflow switch 13, so that the water pipes 102 and 103 are connected to the storage tank 11 and the crusher 14 again. Water supply starts, and as a result, normal operation of the disposer 1 is resumed.

  When an overflow occurs in the treatment tank 21 of the garbage disposal apparatus 2, the operation permitting unit 15 stops the operation of the disposer 1, and the electromagnetic valve 12 is also closed. For this reason, conveyance of the garbage and tap water from the conveyance pump 17 to the processing tank 21 stops, and the outflow of the garbage and the tap water in the garbage disposal apparatus 2 to the exterior of the garbage disposal apparatus 2 is prevented. Moreover, the water supply to the storage tank 11 and the crusher 14 from the water pipes 102 and 103 is also stopped, and as a result, excessive water supply to the storage tank 11 accompanying the stop of the transport pump 17 is prevented.

  The disposer 1 that is prohibited from transporting garbage by the garbage processing apparatus 2 turns off the operation lamp 162 and the standby lamp 163 and does not automatically resume operation. The operator visually recognizes that the standby lamp 163 is turned on and knows that the conveyance of the garbage to the garbage processing apparatus 2 is permitted. The operator operates the operation button 164 to turn on the operation lamp 162 and to insert the inlet 141. Dispose of garbage. In this way, since the disposer 1 that has once stopped operation does not resume operation without permission, for example, the operator is prevented from being damaged by the crusher 14 that suddenly started operation, and safety is improved.

  In the disposer 1 as described above, the overflow switch 13 functions as detection means for detecting the water level of the storage tank, and the solenoid valve 12 executes water supply by the water supply unit 10 according to the level of the water level detected by the detection means. Functions as switching means for switching between / stop.

The CPU 20 of the garbage processing apparatus 2 functions as a prohibiting unit that gives the disposer 1 an instruction to prohibit the transport of garbage from the disposer 1 by executing / stopping the output of the permission signal to the operation permission unit 15.
In addition, the operation permission unit 15 of the disposer 1 receives a prohibition instruction for conveying garbage, and stops the motor 14m and the transport pump 17 of the crusher 14 when the reception means receives the prohibition instruction. It functions as a stopping means for stopping water supply by the water supply unit 10.

The disposer 1 may include a CPU that outputs a signal for switching opening and closing of the electromagnetic valve 12 to the electromagnetic valve 12 instead of the overflow switch 13 and a water level sensor that detects the water level of the storage tank 11. In this case, the CPU determines whether or not the water level detected by the water level sensor is equal to or higher than the overflow water level. If the water level is equal to or higher than the overflow water level, the CPU closes the electromagnetic valve 12.
In addition, when overflow occurs on the garbage processing apparatus 2 side, the transport pump 17 is stopped, but the operation of the crusher 14 and the water supply to the disposer 1 continue, and when the overflow occurs in the storage tank 11, the crusher The structure which stops each of the action | operation of 14 and the water supply to the disposer 1 may be sufficient.

Further, the water supply unit 10 may be configured to supply water only to the crusher 14 or may be configured to supply water only to the storage tank 11. When the water supply unit 10 supplies water only to the storage tank 11, the operator manually starts and stops supplying tap water to the crusher 14.
Furthermore, the timing of stopping the output of the permission signal to the operation permission unit 15 by the CPU 20 is not limited to when the processing tank 21 overflows.
Further, the disposer 1 and the garbage disposal device 2 may be operated individually without inputting / outputting the operation signal and the permission signal between the disposer 1 and the garbage disposal device 2. In this case, the instruction for prohibiting the conveyance of garbage may be given to the disposer 1 by the operator via the emergency stop button 166, for example.

Embodiment 2. FIG.
FIG. 5 is a block diagram showing the configuration of the operation panel 22 of the garbage processing apparatus 2 provided in the garbage processing system 3 according to Embodiment 2 of the present invention.
Unlike the disposer 1 of the first embodiment, the disposer 1 of the present embodiment does not include the overflow switch 13 but includes a water level sensor 18 that detects the water level of the storage tank 11. The water level sensor 18 outputs the detected water level to the CPU 20 at an appropriate timing.

  Further, a relay 19 is connected in series to the electromagnetic valve 12 of the disposer 1, and the relay 19 is turned on when a water supply permission signal indicating permission of water supply is given from the CPU 20 to the electromagnetic valve 12. When energization is performed and a water supply permission signal is not given, that is, when water supply is prohibited, the power supply is turned off to stop energization of the solenoid valve 12.

The CPU 20 determines whether or not the water level input from the water level sensor 18 is equal to or higher than the overflow water level. If the water level is lower than the overflow water level, the CPU 20 gives a water supply permission signal to the relay 19 (giving a water supply permission instruction) When the valve 12 is opened and the water level is equal to or higher than the overflow water level, the solenoid valve 12 is closed without giving a water supply permission signal to the relay 19 (giving a water supply prohibition instruction).
In this case, the CPU 20 may use a constant water level as the overflow water level of the storage tank 11, and may change the level of the overflow water level according to, for example, the water level of the processing tank 21 and the processing status of garbage disposal.

  Other parts corresponding to those in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

In the above disposer 1, when the overflow occurs in the storage tank 11, the electromagnetic valve 12 is closed by the CPU 20 and the relay 19, so that water supply from the water pipes 102 and 103 to the storage tank 11 and the crusher 14 is not performed. As a result, excessive water supply to the storage tank 11 is prevented.
When the overflow is eliminated by the operation of the transport pump 17 after the water supply is stopped, the electromagnetic valve 12 is opened by the CPU 20 and the relay 19, so that the water supply from the water pipes 102 and 103 to the storage tank 11 and the crusher 14 is again performed. As a result, the normal operation of the disposer 1 is resumed.

That is, the water level sensor 18 of the disposer 1 functions as a detection unit that detects the water level of the storage tank 11 and a notification unit that notifies the outside of the water level detected by the detection unit.
In addition, when the notification means notifies the water level detected by the detection means, the CPU 20 of the garbage disposal apparatus 2 instructs whether to permit water supply, that is, a water supply permission instruction / in accordance with the level of the notified water level. It functions as a permission / refusal instruction means for giving a prohibition instruction to the disposer 1.

  The relay 19 of the disposer 1 functions as a permission / rejection reception unit that receives a water supply permission / rejection instruction, and the solenoid valve 12 supplies water by the water supply unit 10 when the permission / rejection reception unit receives a water supply permission / prohibition instruction. It functions as a water supply switching means for switching between execution / stopping.

  When the disposer 1 is provided with an overflow switch using a float switch instead of the water level sensor 18 and a signal is input to the CPU 20 when the water level of the storage tank 11 is equal to or higher than the overflow water level, and this signal is input Alternatively, the CPU 20 may determine that the storage tank 11 is overflowed and close the state without giving a water supply permission signal to the electromagnetic valve 12.
