Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a kitchen waste processing apparatus capable of safely processing kitchen waste and the like.

[0002]

2. Description of the Related Art Conventionally, most garbage disposal devices are composed of a single disposer, and the garbage generated in the sink is crushed together with an appropriate amount of water into a size that does not clog the drainage pipe, and is then discharged into the sewer through the drainage pipe. Was there. The wastewater used in the sink when the disposer was stopped had a structure that could be drained to the sewer through the disposer.
Therefore, a conventional kitchen waste processing apparatus will be described below.
FIG. 5 is a block diagram of a conventional garbage processing device.

As shown in FIG. 5, 1 is a sink, 2 is a disposer, 3 is an inlet of the disposer 2, 4 is a lid,
Reference numeral 5 is a main body connecting rubber for connecting the disposer 2 to the input port section 3, and 6 is a hopper for accommodating the garbage etc. input from the input port section 3. Since a large amount of water in addition to kitchen waste flows from the sink 1, the lid 4 is provided with a hole or the like through which water can pass. Reference numeral 7 is a hammer for crushing the garbage etc. in the hopper 6 that has been thrown in, 8 is a shredder equipped with a fixed blade for crushing the garbage etc. in cooperation with the rotating hammer 7, and 9 is a flywheel. The hammer 7, the flywheel 9 and the like form a crushing portion of the disposer 2. Reference numeral 10 is a driving means such as a motor for rotating the hammer 7, 11 is a drainage pipe for discharging crushed garbage, and 12 is a control means for controlling the driving means 10 which is composed of a microcomputer or the like and is attached to a side surface of the disposer 2. It is housed in a control box. Reference numeral 13 is a start signal input means, and 14 is a stop signal input means, which are operably mounted on an operation panel mounted on the surface of the control box. In the conventional example shown in FIG. 5, the start signal input means 13 and the stop signal input means 14 are start / stop switches, and one switch serves both.

Next, the kitchen waste processing operation of this kitchen waste processing apparatus will be described. First, the lid 4 is opened and kitchen waste or the like is put therein. Next, the lid 4 is closed and the start signal input means 13 on the operation panel is operated while flowing water from the faucet of the sink 1. Receiving this signal, the control means 12 starts driving the driving means 10. When the drive means 10 is driven, the disk-shaped flywheel 9 starts to rotate, and centrifugal force begins to act on the hammers 7 that are pivotally supported on the flywheel 9 in a swingable manner. Then, the hammer 7 starts oscillating around the pin for the shaft support, the center of gravity of the hammer 7 is positioned radially outward, and the hammer 7 is kept open outward and continues to rotate. Become. The kitchen waste etc. contained in the hopper 6 becomes with the water supplied from the faucet, and is crushed by the hammer 7 and the shredder 8. The crushed kitchen waste or the like flows down below the shredder 8 through the gap between the flywheel 9 and the shredder 8. The lower surface of the flywheel 9 is provided with an inclined surface for guiding the crushed kitchen waste or the like to the drain pipe 11. The kitchen waste that flows down flows according to the slope of the inclined surface and flows into the drain pipe 11.
The crushing sound is heard while the kitchen waste remains in the hopper 6, so crushing is continued during this time, and when the crushing sound is stopped, the stop signal input means 14 of the operation panel mounted on the control box is operated. The driving means 10 is stopped. Then, the water supply that had been injected from the faucet for crushing was stopped, and a series of kitchen waste processing was completed.

By the way, in this conventional garbage treating apparatus, such garbage is treated by the disposer 2 and then the crushed garbage is discharged directly from the drain pipe 11 to the sewer. Further, since the lid 4 is formed with a hole that allows water to pass therethrough, the water used in the sink was passed through the lid 4 and the inside of the disposer 2 as sewage, and was similarly discharged to the sewer. . However, the fact that crushed kitchen waste is directly discharged into the sewer system has started to be questioned because it may cause clogging in the sewer system and increase the BOD, which causes environmental deterioration. By using a kitchen waste treatment device that combines a kitchen wastewater and a dehydrator, a device that compresses and dewaters kitchen waste that has been crushed with a disposer with a dehydrator and separates it from the wastewater and the water used for crushing has been proposed. There is.

[0006]

However, in these conventional kitchen waste processing devices, when the kitchen waste is thrown into the hopper in the disposer and crushed, the garbage is driven after the disposer is driven. When crushing or crushing kitchen waste, an additional amount of kitchen waste may be thrown in through the charging port.At this time, the user accidentally thrusts his hand into the rotating disposer or the kitchen waste being crushed There was a possibility of jumping out of the disposer or bouncing back when thrown in later by the centrifugal force of a rotating hammer or garbage.

When a larger kitchen waste or the like is thrown in, or when a large amount of kitchen waste is thrown in at one time, in the conventional kitchen waste processing apparatus, the kitchen waste piled up in the hopper interferes with the insertion of the lid. Insufficient insertion occurred in many cases, and uneven distribution of kitchen waste, etc. often occurred, and this unevenness sometimes caused the lid body to tilt. In order to correct the insertion degree and inclination of the lid, the user needs to touch the lid, remove the lid and flatten the kitchen waste etc. put in the hopper, and then cover the lid again. Things like driving were being done. At this time, there is a higher possibility that your hand will be stuck in and bouncing of kitchen waste will increase.
Especially it was necessary to be safe. It is unsanitary and troublesome for the user to remove the lid and directly handle the kitchen waste etc. by hand. In order to prevent such a situation, it is necessary for the user to first finely dispose of the kitchen waste etc. and then put it in the disposer, or divide it into a small amount of kitchen waste and throw it in and crush it. This is a very troublesome process for the user.

If large garbage is not crushed or leveled and is thrown in and crushed as it is, there is a problem that the crushing efficiency of the garbage processing device is deteriorated.

Therefore, in order to solve such a conventional problem, the present invention provides a method in which a user puts his / her hand into the crushing part during crushing of kitchen waste or the like, or the kitchen waste or the like being crushed pops out or throws in the kitchen waste or the like. An object of the present invention is to provide a garbage disposal device that is safe from bounces and is capable of smoothing garbage etc. without directly touching the garbage etc.

[0010]

And a control means for stopping the drive means in response to a signal from the temporary stop determination means.

An abnormality determining means is provided for determining an abnormality in the attachment state of the lid by a detection signal from the lid detecting element.
When the lid body is in an abnormal attachment state, it is preferable that the control means displays an abnormality on the display means.

The lid detecting element is a reed switch provided in the insertion opening, and it is suitable to detect the approach of the magnet provided in the lid.

It is desirable to provide a plurality of lid detection elements. It is suitable that two lid detecting elements are provided and the temporary stop judging means temporarily stops the driving means when both of the lid detecting elements are OFF signals.

It is a garbage processing flowchart of the garbage processing apparatus in an Example. In addition, in FIG. 1 and FIG.
The components having the same reference numerals as those of the conventional garbage processing device described above have the same basic functions, and thus detailed description thereof will be omitted.

In FIGS. 1 and 2, 1 is a sink, 2 is a disposer, 3 is an input port, 4 is a lid, 5 is a body connecting rubber, 6 is a hopper, 7 is a hammer, 8 is a shredder, and 9 is a fly. Wheels, 10 are driving means such as a motor,
11 is a drain pipe. The hammer 7, the flywheel 9 and the like constitute the crushing unit of this embodiment. The lid 4 of this embodiment is
As shown in FIG. 2, a female screw is formed on the inner circumference and the lid 4
The cup-shaped lid body A24 formed with a knob screwing portion for screwing the knob and the male screw screwed with the female screw of the cup-shaped lid body A24 are formed around and on the side which is the hopper 6 side. It is composed of a cup-shaped lid B25 having a cylindrical pressing portion such as a kitchen waste that is slightly smaller than the outer diameter of the male screw, and a charging port 3 of the sink 1 and a sealing rubber whose outer shape is exactly matched. Both the cup-shaped lids A24 and B25 are made of hard resin. The kitchen waste pressing portion can hold the head of kitchen waste in the hopper 6 by pressing the lid 4 and pressing it from above. If the distribution state in which the garbage etc. is thrown in is biased, it can be flattened by the pressing portion such as the kitchen waste. Reference numeral 12 is a control means for controlling the driving means 10 and also for controlling the display means 20 and the water injection means 22, which is configured by using a microcomputer or the like and is housed in a control box provided near the disposer 2. Reference numeral 13 is a start signal input means, and 14 is a stop signal input means. In the case of this embodiment, the start signal input means 13 and the stop signal input means 14 are provided separately, but one switch may also serve as a start / stop switch. The start signal means 13 and the stop signal input means 14 are provided on the operation panel provided on the surface of the control box.
Reference numeral 15 denotes a drain pipe joint, which partially stores the remaining water of the overflowed water out of the water poured from the sink 1, and controls the water injection means 22 described later when crushing the garbage etc. The hopper 6 can be filled with water.

Reference numeral 16 is a lid detecting element a, and 17 is a lid detecting element b. The lid detecting element a16 and the lid detecting element b
Reference numeral 17 is a reed switch a and a reed switch b in this embodiment, but may be a proximity switch, a photoelectric switch, or a limit switch. A limit switch is cheap. Further, the lid detection element a16 and the lid detection element b
Although two 17 are provided symmetrically in this embodiment, more than one may be provided in some cases, as will be described later. If a plurality of them are provided, it is possible to obtain more accurate information on the attachment state of the lid. Since the lid detecting element a16 and the lid detecting element b17 are the reed switches a and b,
A magnet 19 is provided in the lid 4 for detecting the position. Depending on the number of lid detection elements, magnet 19
Any number can be provided. Here, the magnet 19 is a single disk, and is sandwiched and fixed by the grip screw portion of the cup-shaped lid body A24 and the cup-shaped lid body B25.

When the lid 4 is mounted at the proper position, the magnet 19 can turn on both the reed switches a and b. In the present embodiment, the two reed switches a and b having the same detection ability are arranged at slightly different distances from the regular position of the magnet 19, so that when the lid 4 deviates from the regular position, Alternatively, the reed switch on the far side is immediately turned off. Considering the direction of inclination, it is preferable to arrange the reed switches a and b on the far side in opposite positions. However, when the reed switches a and b are mounted at the proper positions, both reed switches a and b are turned on although the distances are slightly different. This is because the response distance is selected for each of the reed switches a and b. If there is a mismatch between the detection signals detected by the two reed switches a and b, the lid 4 is inserted into the insertion opening 3 because the kitchen garbage or the like is pushed up. It can be determined that the lid body 4 has an abnormal attachment state, if it is not sufficient or if it is attached at an angle. Of course, the reed switches a and b may have the same distance. The abnormality determining means 26 determines whether or not the detection signals of the lid body detecting element a16 and the lid body detecting element b17 match, and if they do not match, the lid body 4 is detected.
Is determined to be abnormal, and when the detection signals of the lid detection element a16 and the lid detection element b17 match, the two detection signals are sent to the temporary stop determination means 27.

In order to surely detect that the lid 4 is tilted and attached, at least three or more reed switches may be arranged at equal intervals around the magnet 19. If the detection signal detected by at least one of the three or more reed switches does not match the detection signal detected by the other reed switches, it is determined that there is an attachment state abnormality such as inclination. Good.

In the temporary stop judging means 27, when the detection signals of the lid body detecting element a16 and the lid body detecting element b17 are both OFF signals, the lid body 4 is removed and the insertion opening 3 is opened. When it is determined that the driving means 10 is in the on-state, the control means 12 suspends the driving means 10. If the lid detection element a1
6. If all the detection signals of the lid detection element b17 are ON, the temporary stop determination means 27 determines that the lid 4 is normal, and the control means 12 receives the water injection means 22 and the drive means 1.
0 is started. Then, even if the detection signals of the lid body detection element a16 and the lid body detection element b17 are both turned off and temporarily stopped by removing the lid body 4, the lid body 4 is reattached and both signals are turned on. When the temporary stop determination means 27 determines that both of the two detection signals are ON at that time, the control means 12 restarts the drive means 10.

Reference numeral 18 is a connecting pipe for sending kitchen waste crushed in the crushing section to the pressure pump 28. The kitchen waste in a slurry state is sent to the pressure feed pump 28 while separating gas and liquid in the connecting pipe 18. The separated air is discharged to the hopper, and the kitchen waste is sent to the pressure feed pump 28. Two
Reference numeral 0 is a display means such as a liquid crystal, 21 is an overheat prevention detecting element such as a thermistor, and 22 is a water injection means such as a water injection valve. The water injection means 22 is provided below the drain pipe joint 15 and stores a part of the water discharged from the sink 1. The control means 1
2 drives the motor of the water injection means 22 and opens it,
Water is injected from the water injection pipe 23 into the hopper 6. The water injected from the water injection means 22 is supplied to facilitate the crushing in the crushing section and to facilitate the transportation of the crushed kitchen waste or the like. The overheat prevention detecting element 21 is the driving means 1
It is provided in the vicinity of 0, and detects that the driving means 10 becomes unrotatable due to biting of garbage or the like in the crushing portion and is in an overheated state. When the overheat prevention detecting element 21 detects an overheated state, a signal indicating overheat is sent to the control means 12.
Then, the control means 12 stops the driving means 10.

The display means 20 is controlled by the control means 12, but at the same time, when a start signal from the start signal input means 13 is input, a display indicating that the start is being made is displayed, and the abnormality determining means 2
When 6 determines that the attachment state of the lid 4 is abnormal, it displays that there is an abnormality, and when the temporary stop determination means 27 determines that it is a temporary stop, it displays a temporary stop to prevent overheating. When the detection element 21 detects an overheated state, it indicates that it is in an overheated state.

The pressure feed pump 28 sends the kitchen waste etc. in the slurry state to a kitchen waste processing tank (not shown). The garbage processing tank is basically composed of three tanks. First of all
The tank is a decomposition tank that anaerobically disposes of kitchen waste sent from the disposer 2, the second tank is an aeration tank that aerates the liquid transferred from this decomposition tank with aerobic soil bacteria, and the third tank is This is a settling tank that separates the sludge in the liquid sent from the aeration tank. Since the garbage treating apparatus of this embodiment includes the disposer 2, the pressure pump 28, and the garbage treating tank, only the supernatant liquid can be discharged. See also Disposer 2
It is also possible to provide a dehydrator in addition to the pressure feed pump 28, and to crush waste such as kitchen waste and then solid-liquid separate with a dehydrator to compress the solid matter and discard it.

Next, a series of operations of the garbage processing apparatus in this embodiment will be described with reference to FIGS. When the user needs to throw in garbage etc., the lid 4 is opened and the garbage is thrown into the hopper 6 in the disposer 2. If there is a bias in the distribution of the state of garbage such as kitchen waste in the hopper 6,
The lid 4 is attached to the insertion opening 3 while pressing the lid 4 to make it smooth. When the user presses the activation signal input means 13 on the operation panel, the activation input signal is sent to the control means 12, and the control means 12 causes the display means 20 to display that the activation is in progress. Further, the lid detecting element a16 and the lid detecting element b17
The detection signal detected by is sent to the abnormality determination means 26, and it is determined whether or not they match. If the two do not match, it is determined that the mounting state of the lid 4 is abnormal, and the control means 12 causes the display means 20 to display an abnormality. If they match, it is determined that the lid 4 is in the normal state or the state in which the lid 4 is removed from the insertion opening 3, and the detections detected by the lid detecting element a16 and the lid detecting element b17 are detected. The signal is sent to the temporary stop determination means 27.

In the temporary stop judging means 27, if the detection signals detected by the lid detecting element a16 and the lid detecting element b17 are both ON signals, it is judged that the lid 4 is at least in the normal position. But both are OF
If the signal is the F signal, it is determined that the lid 4 is in the removed state. Lid detection element a16, lid detection element b
If all the detection signals detected by 17 are OFF,
The temporary stop determination means 27 temporarily stops the water flow of the water injection means 22 and also temporarily stops the drive of the drive means 10. On this occasion,
Since there is a problem in safety when the temporary stop is performed for a long time, when the first set time elapses after the temporary stop is started, the first means for forcibly stopping the water injection means 22 and the drive means 10 is used. One timer safety means is provided.

If the lid detecting element a16 and the lid detecting element b
When all the signals detected by 17 are ON, the control means 12 uses the signal from the temporary stop determination means 27 to drive the drive means 1.
0 and the water injection means 22 will be driven. The water passage means 22 and the driving means 10 which are temporarily stopped are kept in the monitoring state until the first set time of the control means 12 elapses, and if the detection signals of the lid body detecting element a16 and the lid body detecting element b17 are detected. When both are turned on, the control means 12 again activates the water injection means 22 and the drive means 10 at that time. Further, if the drive means 10 and the water injection means 22 are driven for too long, a second timer safety means for forcibly stopping the drive means 10 and the water injection means 22 is provided when the second set time has elapsed. There is.

The control means 12 is a drive means 10 and a water injection means 2.
After driving No. 2, the operation of the overheating prevention operation of the driving means 10 is started to check if there is an overheat signal from the overheat prevention detecting element 21. If it is overheated, the water injection from the water injection means 22 is stopped and the drive of the drive means 10 is stopped. If it is not overheated, the control means 12 checks whether or not the stop signal input means 14 is input to stop the garbage processing device. If the stop signal is input from the stop signal input means 14, the control means 12 stops the water injection means 22 and the drive means 10, and ends a series of garbage processing. If the stop signal is not input, the control means 12 will continue and repeat these series of operations, and will continue monitoring.

As described above, according to the present embodiment, since the abnormality determination and the temporary stop determination of the lid body 4 are continuously performed and the wearing state of the lid body 4 is continuously monitored, the wearing state of the lid body 4 remains incomplete. It is safe because the user does not put his hand in the crushing operation, the kitchen garbage or the like during the crushing does not pop out, and the thrown garbage or the like does not bounce off while continuing the operation.

Next, an apparatus for treating garbage etc. according to another embodiment of the present invention will be explained. FIG. 4 is a control circuit diagram of a kitchen waste processing apparatus according to another embodiment of the present invention. In this embodiment, the control circuit constitutes an abnormality determination means, a temporary stop determination means, a control means and the like. Except for this control circuit, the other structure is the same as that of the embodiment shown in FIG. First, in the control circuit, when the switch SW1 which is the start signal input means is pressed, SW1 is turned on. Next, when the reed switches LSa and b, which are the lid detection element a16 and the lid detection element b17 of the present embodiment, are both turned on by the action of the magnet 19 inside the lid 4, the reed switch LSa side relay R1 and the reed switch are connected. The relay R2 on the switch LSb side is excited. Then, contact a of R1 R1-1
And the a-contact R2-1 of R2 are both turned on. At this time, the b-contact R1-2 and the b-contact R2-2 are turned off. The time relay TR1 is excited by the a-contact R1-1 and the a-contact R2-1. The time relay TR1 is turned on with a slight delay of 0.5 sec, and the b-contact TR1-2 is opened. Therefore, the lamp PL2, which is a display unit for displaying an abnormality, does not light up. If neither the relay R1 on the side of the reed switch LSa nor the relay R2 on the side of the reed switch LSb is excited due to removal of the lid 4 or the like, the b contact point R1-2 and the b contact point R2-2 are O.
At N, the a-contact R1-1 and the a-contact R2-1 are turned off. Time relay TR1 has b-contact R1-2 and b-contact R2
When it is excited by −2, the b-contact TR1-2 is opened, and in this case also, the lamp PL2 does not indicate an abnormality.

If the reed switch LSa side relay R1
If either one of the relay and the relay R2 on the reed switch LSb side is excited and the other is not excited, the a contact R1-1
And one of the a-contact R2-1 are ON and the other is OFF
In addition, since one of the b contact R1-2 and the b contact R2-2 is ON and the other is OFF, the time relay TR1 is not excited. Therefore, the b contact TR1-2 is O
If it is N, the display means gives an abnormal display. As described above, the relays R1 and R2, which are the abnormality determining means 26, and their contact points, R1-1, R2-1, and R.
The abnormality determination is performed by 1-2, R2-2, time relay TR1 and its contact point TR1-2.

The control circuit of this embodiment also makes a temporary stop decision. When the reed switches LSa and b are turned on by the magnet 19, the relays R1 and R2 are excited and the a contact R1-
Since the 2 and a contact R2-2 are turned on, the relay R3 is excited. As a result, the contact a R3-1 is turned on. Since the reed switches LSa and b are ON, a contact R1
-1 and the a contact R2-1 are also ON, and the a contact TR1-1 of the time relay TR1 is also ON. Further, the b-contact TR3-1 of the time relay TR3 for defining the second set time, which will be described later, is also ON, and when the switch SW2, which is the stop signal input means, is not pressed, SW2 is conductive, so the relay R4 is excited. When the a-contact R4-1 is turned on by the relay R4, the b-contact TR2-1 of the time relay TR2 and the b-contact R5-1 of the time relay TR5, which will be described later, are on, so that the SW1 is held by itself even after being pressed. The relay R4 is for setting an operating condition as to whether or not the disposer 2 can be operated. When the relay R3 and the relay R4 are turned on, the a contact R4-3 and the a contact R3-2 are turned on, and the relay MC
1 turns ON. A contact MC1-1 and a of relay MC1
The contact point MC1-2 is turned on, and the motor M1 that is the driving unit 10 and the water injection valve motor M2 that is the water injection unit 22 are driven. By the way, when the lid 4 is removed, the reed switches LSa and b are turned off and the relay R3 is de-energized. However, even if the a-contact R3-1 of the relay R3 is opened, the relay 4 remains excited because the SW1 is held by itself. Then, since the a contact R3-2 of the relay R3 is opened, the relay MC1 becomes non-excited and the motor M1
And the motor M2 of the water injection valve is stopped.

This stopped state continues as long as the lid 4 is removed. When the lid 4 is attached at a certain point, the relays R1 and R2 are turned on and the relay R3 is turned on. Then, the a contact R3-2 of the relay R3 is turned on, and the a contact R4-3 of the R4 is also kept on, so that the relay MC1
Is excited, and the motor M1 and the water injection valve motor M2 are driven again. As described above, the temporary stop determination means 2
Reference numeral 7 is a relay R1 and a relay R2, and a contact point R thereof.
1-2, R2-2, relay R3 and its contact point R3-2
For example, the temporary stop determination is carried out.

By the way, once the operating condition is satisfied, the relay R
When the lid 4 is removed when the switch 4 is turned on, the excitation of the time relay TR2 is started. The first set time, which is the set time of the time relay TR2, is set to a time of about 60 to 120 sec in which the lid 4 can be taken and thrown in the garbage and the like. When the first set time elapses, the time relay TR2 is turned on and the self-holding circuit of SW1 can be turned off by turning off the a-contact TR1-1, so that the relay R4 is de-energized and the relay MC1 is de-energized. M1 and the water injection valve motor M2 are forcibly stopped.

Similarly, when the disposer 2 continues to be operated for a long time without inputting a stop signal from the stop signal input means 14, it is considered that the idle operation is continued for some reason. To be In such a case, it is preferable to stop the operation for the safety of the disposer 2. Therefore, the time relay TR3 is provided in this embodiment. Normally, the second set time of the time relay TR3 may be set so that the motor M1 and the water injection valve motor M2 can be turned off in a time that is about 2 to 3 times as long as the time when the kitchen waste is normally crushed. The operating condition of disposer 2 is satisfied and relay R4
When a-contact R4-2 is closed, time relay TR3
Turns on. When the second set time elapses without inputting the stop signal from the stop signal input means 14, the b contact TR3-1 of the time relay TR3 is opened and the relay R4 is de-energized. As a result, a contact R4-3 of the relay R4
As a result, the relay MC1 is de-energized, and the motor M1 and the water injection valve motor M2 are forcibly stopped.

When the lid 4 is properly attached and the operating condition is satisfied and the relay R4 is excited, the time relay TR3 is turned on and the relay R is turned on as described above.
Since 3 is also ON, a contact R4-3 and a contact R
3-2 is closed, the relay MC1 is excited, the motor M1 and the motor M2 of the water injection valve are turned on, and the drive of the water injection means 22 and the drive means 10 is started. However, if the motor M1 which is the driving means 10 is overheated at this time, the thermistor LS3 is turned on and the relay R5 is turned on. Then, the b contact R5-1 is opened and the relay 4 is de-energized, and the motor M1 and the motor M2 of the water injection valve are stopped. On the contrary, if the driving means 10 is not overheated, the thermistor LS3 is turned off, and the b contact R5 of the relay R5.
Since -1 remains closed, relay R4 remains energized, relay MC1 is also ON, and motor M1 and motor M2 of the water injection valve continue to be driven. In this state, the driving means 10 continues to drive unless a stop signal is input from SW2 which is the stop signal input means 14, but if the stop signal is input, SW2 for setting the operating condition is cut off,
The relay R4 is de-energized, the a contact R4-3 is opened, the relay MC1 is turned off, and the motor M1 and the motor M2 of the water injection valve are stopped.

As described above, the control circuit of the present embodiment can be temporarily stopped with a simple and inexpensive circuit structure, and the user puts his / her hand into the crushing machine or throws out or throws in the kitchen waste during crushing. It is extremely safe because it does not bounce kitchen waste.
