Description

  The present invention relates to a garbage processing apparatus for pulverizing garbage with water and a sink equipped with the garbage processing apparatus.

  In order to process garbage generated in general households, restaurants, etc., garbage processing apparatuses equipped with a disposer in a sink are rapidly spreading. This is because it is possible to easily dispose of garbage in the kitchen, kitchen, etc., and it does not take time to carry out the garbage after the treatment.

  However, since water must be supplied to the disposer by manually opening and closing the faucet installed in the water supply pipe (manual water supply method), it takes time for the operation and the operation of the garbage disposal device. Forgetting to close the faucet and wasting water due to unfamiliarity with the water, or conversely, if the water supply is insufficient, garbage will remain in the disposer and a bad odor will be generated. When is small, there is a problem that garbage is clogged in the pipe.

  Therefore, it is necessary to supply water to the disposer by the water supply control method (automatic water supply method). This is because the necessary water supply is surely performed by automatic water supply, so that it is possible to prevent garbage from remaining in the disposer and clogging of the garbage in the pipe, and furthermore, there is no waste of water due to forgetting to close the faucet.

  In a conventional automatic water supply type garbage disposal device, as a water supply control means, the open / close operation of an electric valve or a solenoid valve installed in a water supply pipe is controlled by a CPU (Central Processing Unit) or a timer to supply water. A garbage disposal apparatus has been developed (see, for example, Patent Document 1).

  In an automatic water supply type garbage disposal device, when the operation switch is turned on, automatic water supply is preceded first, then the disposer is driven to crush the garbage, and when the operation switch is turned off, the disposer is turned off. It is controlled to stop and stop automatic water supply after a delay.

  With this garbage disposal device, water can be supplied to the disposer without the user manually opening and closing the faucet, so it takes time to operate and is unfamiliar with the operation of the garbage disposal device. Even if there is water, forgetting to close the faucet and wasting water, or conversely, there is not enough water supply and garbage remains in the disposer and no odor is generated. Even if it is small, there is an advantage that garbage is not clogged in the drain pipe.

  However, when a garbage disposal apparatus using an automatic water supply method is used, water supply to the disposer is always automatically performed. For this reason, users who are familiar with the operation of garbage disposal equipment and users at installation sites where the slope of the drain pipe is large have a manual water supply system that can supply water by manually opening and closing the faucet. There are many cases where a garbage disposal device is desired.

On the other hand, what can select an automatic water supply system and a manual water supply system in the operation switch of a garbage processing apparatus is developed (for example, refer to patent documents 2). In this garbage disposal apparatus, there are two operation switches, an automatic water supply mode and a manual water supply mode, and by selecting one of them, water can be supplied to the disposer by an automatic water supply method or a manual water supply method.
JP-A-9-155218 JP 2002-1150 A

  However, in the garbage processing apparatus taken up in Patent Document 1 of the prior art, since the water supply to the disposer is always an automatic water supply system, even if the user desires the manual water supply system, it cannot be handled. Even if a water faucet that can be opened and closed manually is installed without using the water supply control means, the automatic wastewater treatment system is still controlled by the automatic water supply system. The disposer was not driven while the user was waiting, and the user had to wait and lacked convenience.

  On the other hand, in the garbage processing apparatus taken up in Patent Document 2 of the prior art, when it is desired to use the manual water supply method, by selecting the operation switch in the manual water supply mode, immediately after the operation of the garbage treatment apparatus is started. Disposer can be driven, but multiple operation switches are required, and even if only the manual water supply method is used, the water supply control means remains installed, making the device complicated and difficult to cope with downsizing This is the current situation.

  Therefore, if the user wants a manual water supply method, it is desirable to install a dedicated garbage disposal device, but if that happens, a disposer corresponding to each method will be required, and it will not be possible to share models This will increase the cost of the device.

  The present invention solves such a conventional problem, and a small device can be configured without separately providing a plurality of operation switches, and in either case of an automatic water supply method or a manual water supply method with a single type of disposer. It aims at providing the garbage processing device which can respond.

In order to achieve the above object, the present invention provides a disposer, a control unit for controlling the disposer, a water supply control means that is completely insulated from the control unit and selectively attached in the middle of a water supply pipe, and the water supply A detection sensor for detecting the presence or absence of a control means, and the control unit, when the detection sensor detects the water supply control means, precedes water supply before starting the disposer, and supplies water for a predetermined time after the disposer stops. The control mode is set to delay the stop, and when the detection sensor does not detect the water supply control means, the control mode is set to drive only the disposer alone.

  With this configuration, it is possible to achieve an effect that it is possible to provide a garbage disposal apparatus that can be used for either an automatic or manual water supply system with a single type of disposer without providing a plurality of operation switches.

  According to the present invention, there is no need to provide a plurality of operation switches separately, and in the case of the manual water supply method, a water supply control means is not required so that a small device can be configured, and an automatic or manual water supply method using only a single type of disposer. Since it can respond to either, the effect that a low-cost garbage processing apparatus can be provided is acquired.

In the present invention, a disposer, a control unit that controls the disposer, a water supply control unit that is completely insulated from the control unit and selectively attached in the middle of the water supply pipe, and detects the presence or absence of the water supply control unit And a control mode in which, when the detection sensor detects the water supply control means, the control unit delays the water supply stoppage for a predetermined time after the disposer is stopped, and precedes the water supply before starting the disposer. When the detection sensor does not detect the water supply control means, the control mode is set to drive only the disposer alone.

  As a result, there is no need to install multiple switches separately, and in the case of the manual water supply method, a water supply control means is not required, so a small device can be configured, and both automatic and manual water supply methods can be used with only a single type of disposer. Therefore, it is possible to provide an effect that it is possible to provide a low-cost garbage disposal device.

  Further, the disposer may be set so that it can be driven only when the power supply control means is on. In this case, when the power supply control means is installed but the power supply is turned off, the disposer is driven even when there is no water supply by preventing the disposer from being driven. This prevents the garbage from remaining in the disposer and the pipe from being clogged with garbage.

  The detection sensor detects whether the water supply control means is turned on or off, reliably determines the presence or absence of the water supply control means, and switches between control modes when the water supply control means is present and when it is not present. You may make it carry out correctly.

  In addition, as a detection sensor, for example, a sensor using an optoisolator (photocoupler), a sensor using a photometal oxide semiconductor field effect transistor (optical MOSFET), a sensor using an infrared light emitting / receiving section, or a radio wave receiving / transmitting section The ones used can be considered.

  If the garbage disposal apparatus is incorporated in a sink, the usability in the kitchen can be greatly enhanced.

Examples of the basic configuration and examples of the present invention will be described below with reference to the drawings.
( Basic example 1)
As shown in FIG. 1, there is a sink 1 made of stainless steel or artificial marble installed in a kitchen such as a general home or a restaurant, and a disposer 3 is hung and attached to a drain port 2 of the aquarium. Yes.

  At the uppermost part of the disposer 3 and inside the waste outlet 2, a switch 5 made of a resin such as metal or ABS, which also serves as an operation switch for the disposer 3, and a lid of the garbage inlet 4 is attached and detached. A motor 6 is built in the disposer below the garbage input port 4, which is attached in a possible manner, and the garbage input from the garbage input port 4 is put together with water on the upper side of the motor 6. A crushing blade 7 for crushing is rotatably attached to the motor 6.

  A discharge pipe 8 for discharging the garbage crushed by the crushing blade 7 to the outside of the disposer 3 is connected to the side surface near the center of the disposer 3, and the discharge pipe 8 is buried under the floor and is 1/100 in the direction of drainage. It is connected to the drain pipe 9 with the above-mentioned downward slope.

  A control unit 10 incorporating a central processing unit (CPU) is attached to the lower side surface of the disposer 3, and a power cord 11, an input unit 12, and an output unit are provided below the control unit 10. 13 is attached.

  Further, a water supply pipe 14 for supplying water to the disposer 3 is attached to the sink 1, and a water outlet of the water supply pipe 14 is directed downward from above the garbage input port 4.

  An automatic water supply device 15 is installed in the middle of the water supply pipe 14 in the sink 1, and the automatic water supply device 15 includes an automatic valve 16 such as an electromagnetic valve or an electric valve, and supplies water to the disposer 3. Can be controlled.

  The automatic water supply device 15 is equipped with a power cord 17, a detection sensor 18 that detects the presence or absence of the automatic water supply device 15, and a transmission cable 19 that transmits an output signal to the automatic water supply device 15. The output unit 13 of the control unit 10 is connected.

  A magnetic sensor such as a reed switch or a Hall IC is used as the detection sensor 18, and a transmission cable 20 is installed in the detection sensor 18 to input and transmit that there is an automatic water supply device 15 to the control unit 10. The transmission cable 20 is connected to the input unit 12 of the control unit 10.

  Next, FIG. 2 is a manual water supply system without the automatic water supply device 15 described above, and a manual valve 21 that can be manually opened and closed is installed in the middle of the water supply pipe 14. In the case of this manual water supply method, a drain pipe 22 having a large gradient (1/50 or more) is attached.

With the above configuration, the operation of the garbage disposal apparatus in Basic Example 1 will be described with reference to FIGS.

  First, when the automatic water supply device 15 is present, the detection sensor 18 detects that the automatic water supply device 15 is present, and the detected result is input and transmitted from the input unit 12 to the control unit 10 using the transmission cable 20. Upon receiving the input transmission, the control unit 10 switches to the automatic water supply control mode (Y in step ST1).

  Next, when the switch 5 is removed from the garbage input 4 and the garbage is inserted into the disposer 3 from the garbage input 4, and the switch 5 is attached to the garbage input 4, the switch 5 is turned on. The control unit 10 outputs and transmits the automatic valve 16 from the output unit 13 to the automatic water supply device 15 through the transmission cable 19 (step ST2).

  Here, as shown in FIG. 4, when the switch 5 is attached to the garbage input 4, the switch is off, and as shown in FIG. 5, the knob 23 of the switch 5 is rotated to the on position. As a result, the switch 5 is turned on. The water supply flows into the disposer 3 through the slit 24 provided in the switch 5.

  When the automatic water supply device 15 receives the output transmission from the control unit 10, the automatic valve 16 opens and supplies water to the disposer 3 through the water supply pipe 14 (step ST3).

  When a certain time (time T1 in FIG. 3) elapses after the automatic valve 16 is opened, the control unit 10 transmits an output to the motor 6, and the motor 6 starts and the grinding blade 7 rotates to drive the disposer 3. The garbage is pulverized with water (step ST4) and (step ST5).

  Garbage pulverized with water is discharged from the disposer 3 to the discharge pipe 8, and then flows through the drain pipe 9 installed under the floor to be drained outside the sink 1.

  When the user determines that the garbage has been crushed and turns off the switch 5, the control unit 10 immediately stops the output transmission to the motor 6, and the motor 6 stops so that the rotation of the pulverizing blade 7 also stops. The disposer 3 stops (step ST6) (step ST8).

  Even if the user does not turn off the switch 5, the control unit 10 transmits the output to the motor 6 after a certain time (time T <b> 2 in FIG. 3) has elapsed since the disposer is driven to prevent the motor 6 from being heated. It stops and the disposer 3 stops (step ST7).

  Water supply continues even after the disposer 3 stops, but when a certain time (time T3 in FIG. 3) has passed since the disposer 3 stopped, the control unit 10 stops output transmission to the automatic water supply device 15 Then, the automatic valve 16 is closed to stop water supply, and the operation of the garbage disposal apparatus is finished (step ST9) and (step ST10).

  On the other hand, when there is no automatic water supply apparatus 15, since there is no input transmission from the detection sensor 18 to the control part 5, the control part 10 switches to the control mode of a manual water supply system (N of step ST1).

  Next, after the switch 5 is removed from the garbage input 4 and the garbage is inserted into the disposer 3 from the garbage input 4, and the switch 5 is attached to the garbage input 4, the user himself / herself operates the manual valve. When 21 is opened, water is supplied from the water supply pipe 14 to the disposer 3. When the switch 5 is turned on, the control unit 10 transmits an output to the motor 6, the motor 6 is started and the crushing blade 7 rotates to drive the disposer, and the garbage is crushed together with water (step ST11). (Step ST12).

  Since the operation of the switch 5 is the same as in the case of the automatic water supply method, detailed description is omitted here.

  Garbage crushed with water is discharged from the disposer 3 to the discharge pipe 8, and then flows out of the sink 1 through the drain pipe 22 installed under the floor.

  When the user determines that the garbage has been crushed and turns off the switch 5, the control unit 10 immediately stops the output transmission to the motor 6, and the motor 6 stops so that the rotation of the pulverizing blade 7 also stops. The disposer 3 stops (step ST13), (step ST15).

  Even when the user does not turn off the switch 5, the control unit 10 outputs an output signal to the motor 6 after a certain time (time T <b> 2 in FIG. 3) has elapsed since the disposer is driven to prevent the motor 6 from being heated. The disposer 3 stops and stops (step ST14).

As described above, according to the first basic example, a plurality of switches are required to determine the presence or absence of the automatic water supply device 15 in the control unit 10 with the above configuration and to switch to the control mode corresponding to the presence or absence. Instead, a small garbage disposal device can be provided.

  Next, when there is an automatic water supply device 15 as shown in FIG. 1, the water necessary for pulverizing the garbage can be supplied by the automatic water supply control mode, and the water supply is performed even after the disposer 3 is stopped. In order to continue, the crushed garbage does not stay in the disposer 3 or the drain pipe 9 with a small gradient, and the generation of odor due to the garbage remaining in the disposer 3 or the drain pipe 9 is not blocked. Therefore, the garbage disposal apparatus can be used comfortably at all times.

  On the other hand, when there is no automatic water supply device 15 as shown in FIG. 2, the disposer 3 can be used immediately after the switch 5 is turned on in the control mode of the manual water supply method, and the user can treat the garbage disposal device. Since the drainage pipe 22 has a large gradient, the generation of odor due to garbage remaining in the disposer 3 or the drainage pipe 22 may be clogged, as is the case with the automatic water supply device 15. Therefore, the garbage disposal apparatus can be used comfortably at all times.

Furthermore, in the case of the presence or absence of the automatic water supply device 15, since it is possible to use the disposer 3 of the same model as it is without any change or addition, the cost reduction effect by the lineup reduction of the disposer 3 can be obtained. An inexpensive garbage disposal apparatus can be provided.
( Basic example 2)
As shown in FIG. 6, the control unit 10 detects the on / off of the power supply of the automatic water supply device 15 with the detection sensor 18 and determines the presence or absence of the automatic water supply device 15. That is, the detection sensor 18 detects that the automatic water supply device 15 is turned on, and the detection result is input and transmitted from the input unit 12 to the control unit 10 using the transmission cable 20.

Upon receiving the input transmission, the control unit 10 switches to the automatic water supply control mode. Since the subsequent operation is the same as the automatic water supply method of the basic example 1, detailed description is omitted here.

As can be seen from FIG. 7, in the case of the manual water supply method, the automatic water supply device 15, the detection sensor 18, the transmission cable 19, and the transmission cable 20 in FIG. Instead, the control unit 10 switches to the manual water supply control mode. Since the subsequent operation is the same as the manual water supply method of the basic example 1, detailed description is omitted here.

As described above, according to the second basic example, with the above configuration, the on / off of the power supply of the automatic water supply device 15 is detected by the detection sensor 18 and input to the control unit 10 and transmitted to the control unit 10. By determining the presence or absence of the water supply and switching to the control mode corresponding to the presence or absence, it is possible to reliably determine whether or not the automatic water supply device 15 is present, so that the high-quality and highly reliable garbage disposal device Can be provided.
( Basic example 3)
8 and 9, the difference from the basic example 1 and the basic example 2 is that the input unit 25 attached to the control unit 10 can detect the connection of the transmission cable 20 and perform input transmission to the control unit 10. Basic example 1 is about the principle of the garbage processing apparatus which grinds garbage with water by attaching the buzzer 26 to the part 10 and enabling the control part 10 to operate the buzzer 26 as needed. This is the same as the basic example 2.

  By using a connector or the like that is partially shorted for the input unit 25, it is possible to detect the connection of the transmission cable 20 and to input and transmit it to the control unit 10.

With the above configuration, the operation of the garbage disposal apparatus in Basic Example 3 will be described with reference to FIGS.

First, in the case of the automatic water supply method, when the power supply of the automatic water supply device 15 is turned on, it is the same as the basic example 1 and the basic example 2, and therefore detailed description thereof is omitted here. (Step ST1 to Step ST10).

  When the power supply of the automatic water feeder 15 is off, there is no input transmission from the detection sensor 18 to the control unit 10, but since the transmission cable 20 is connected to the input unit 25, the connection of the transmission cable 20 is connected to the input unit. 25, the control unit 10 determines that the power supply cannot be operated because the automatic water supply device 15 is present even though the automatic water supply device 15 is present, and switches to the control mode of the automatic water supply method (power supply off). (Step ST1), (Y of step ST16).

  When the switch 5 is turned on in this state, the buzzer 26 is operated to notify the user that the automatic water supply apparatus cannot be operated (step ST17) and (step ST18).

  Thereafter, when the switch 5 is turned off, the buzzer 26 is stopped (step ST20).

  The disposer 3 is not driven in the control mode of the automatic water supply method (power off).

In the case of the manual water supply method, since it is the same as the basic example 1 and the basic example 2, detailed description is omitted here.

Thus, according to the present basic example 3, even when the automatic water supply method is used, when the power is off, it is determined that the automatic water supply device 15 cannot be operated, and the buzzer 26 notifies the user, In addition, since the control mode is switched so as not to drive the disposer 3, the garbage is not crushed even if there is no water supply, and the crushed garbage remains in the disposer 3 to generate a bad odor, Since the crushed garbage does not become clogged in the drain pipe 9, the garbage processing apparatus can be used comfortably and safely.

In FIG. 11, an optical isolator (photocoupler) 27 is used for the detection sensor 18, and the photocoupler 27 includes an LED 28 and a phototransistor 29.

  One of the photocouplers 27 is connected to the automatic water supply device 15 and the other is connected to the output unit 30 of the detection sensor 18.

Thus, the input is transmitted from the input unit 12 to the CPU 31. The automatic water supply device 15 and the control unit 10 are completely insulated by the LED 28 and the phototransistor 29.

  Receiving the input transmission, the CPU 31 switches to the automatic water supply control mode. When water is supplied in this control mode, output is transmitted from the CPU 31 to the transistor 33. When the transistor 33 is turned on, output is transmitted from the output unit 13 to the automatic water supply device 15 through the transmission cable 19, and the automatic water supply device 15 is transmitted.

Therefore, it is possible to provide a high-quality and highly reliable garbage disposal apparatus.
(Example 2 )

The second embodiment is different from the first embodiment in that a photo-oxide metal semiconductor field effect transistor (optical MOSFET) 36 is used for the detection sensor 18, and the detection sensor 18 detects the power supply of the automatic water supply device 15. The principle is the same as in the first embodiment. In the optical MOSFET 36, an LED 37 and an FET 38 are installed.

The second embodiment configured as described above will be described with reference to FIG.

  When the power supply of the automatic water supply device 15 is on, a current flows to the optical MOSFET 36, the LED 37 emits light, and when the FET 38 is turned on accordingly, a current flows from the control power source 32 and is input from the output unit 30 through the transmission cable 20. The input is transmitted from the unit 12 to the CPU 31. The automatic water supply device 15 and the control unit 10 are completely insulated by the LED 37 and the FET 38.

Therefore, it is possible to provide a high-quality and highly reliable garbage disposal apparatus.
(Example 3 )

Further, by performing wireless transmission by the radio wave transmission / reception units 42 and 44, the garbage disposal apparatus can be freely laid out in the sink.

In the above example , the water supply pipe 14 in FIGS. 1, 2, and 8 supplies water to the disposer 3 from above the sink 1, but the present invention is not limited to this, and for example, the water supply pipe 14 It is good also as a structure which connects directly to the disposer 3 and supplies water.

  The control unit 10 is attached to the disposer 3, but may be attached to a place different from the disposer 3 or may be attached to the automatic water supply device 15, for example.

  The detection sensor 18 is installed near the automatic water supply device 15, but may be installed near the disposer 3 or directly on the disposer 3 or the control unit 10 as long as the presence or absence of the automatic water supply device 15 can be detected. good.

  In FIG. 4 and FIG. 5, the movement from the OFF state to the ON state of the switch 5 is the clockwise direction, but this is not a limitation.

  In addition, in order to ensure the safety of the user, when the switch 5 is turned on, that is, in the operating state of the garbage disposal device, in order to prevent the user's hand from accidentally entering the disposer 3 from the garbage inlet 4, It is better to provide a lock mechanism for the switch 5 and the garbage input port 4 so that the switch 5 cannot be removed when the switch 5 is on.

  In the automatic water supply method of FIGS. 3 and 10, the time from when the switch 5 is turned on until the automatic valve 16 of the automatic water supply device 15 is opened is not particularly shown. Alternatively, it may be opened after a certain time from turning on the switch 5, for example, after about 1 to 3 seconds, preferably after about 2 seconds.

  In the manual water supply method, the time from when the switch 5 is turned on until the disposer 3 is driven is not particularly shown, but it may be driven immediately after the switch is turned on, or after a certain time from the switch on, for example, 1 It may be driven about 3 seconds later, preferably about 2 seconds later.

  The time T1 is not particularly shown, but it is desirably about 3 to 7 seconds, preferably about 5 seconds. The time T2 is about 1 to 3 minutes, preferably about 1 to 1 minutes and 30 seconds. Further, it is desirable that the time T3 is about 5 to 10 seconds, preferably about 7 to 8 seconds.

  The water supply flow rate of the automatic water supply method is desirably about 8 to 10 liters per minute, preferably about 9 liters per minute.

8, 9 and 10, when the automatic water supply device 15 is turned off, a buzzer is used as a method for notifying the user that the automatic water supply device 15 cannot be driven. The invention is not limited to this. For example, when a lamp such as an LED is installed outside the sink 1 and is easily visible to the user, and the switch 5 is turned on in the control mode of the automatic water supply method (power off), The lamp may be turned on or blinked. In addition, the user may be notified by a liquid crystal display or the like instead of the lamp.

  As described above, the garbage processing apparatus of the present invention can be configured manually from an inexpensive and small-sized apparatus. For example, after the user has mastered the operation of the garbage processing apparatus, the automatic water supply apparatus can be manually supplied with water. By changing to a water supply valve, the power required for the automatic water supply device can be saved, and users who are familiar with the operation of the garbage disposal device in one housing complex coexist with unskilled users. In such a case, it is possible to use a garbage disposal apparatus of either a manual water supply method or an automatic water supply method according to the user's request.
