Abstract

PROBLEM TO BE SOLVED: To supply water at a required flow rate for a required period of time without wastefully consuming water by placing an automatic valve at an appropriate position of a water supply pipeline and supplying a specified amount of water into a disposer for crushing garbage, etc., to prevent a pipeline of waste water discharged from the disposer from being plugged. SOLUTION: In this device, a disposer 2 in which a rotary table that is fitted with blades and placed horizontally is rotated with a motor placed in a cylindrical vessel is used for subjecting garbage charged into the disposer 2 to crushing treatment. At this time, the startup/shutdown of the device are performed by the closing/opening of a cover of the disposer 2 or on/off of an external switch 7 respectively. Accordingly, only by charging garbage into the disposer 2 and closing the cover, water is supplied to the disposer 2 at a specified flow rate for a prescribed period of time and the garbage can be crushed without plugging a waste water pipeline. Also, since the disposer 2 can not be operated unless the cover is closed, the disposer 2 is not damaged even at the time of dropping a spoon or the like into the disposer 2.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply device for a disposer for supplying a predetermined amount of water to a disposer for crushing raw garbage or the like for a predetermined time.

[0002]

2. Description of the Related Art Conventionally, when disposing of raw garbage produced at home, only the garbage has been thrown together on a predetermined day. In addition, there was a method in which a disposer was installed at the sink's outlet to crush raw garbage and the like, and to dispose of it into a drain pipe together with water.

In the processing method using a disposer, the stopper at the sink is removed, the faucet is opened, and water is caused to flow into the disposer. Next, the garbage is gradually put into the disposer, the lid which is the operation switch is closed and the disposer is operated, and the garbage is flushed with the water into the drain pipe. After the crushing is completed, the operation is continued while flowing a certain amount of water into the disposer for a predetermined time to clean the inside of the disposer and prevent the drain pipe from being clogged.

As described above, since the waste can be crushed into pieces on the spot by the disposer and the waste can be made to flow together with water into the drain pipe, unlike the former case.
It is sanitary because it is possible to dispose of garbage without soiling hands and it is not necessary to store the garbage until the garbage collection day.

[0005]

However, in the above-mentioned conventional disposer, it is necessary to flow a certain amount of water from before crushing the garbage to after crushing it. It had to be washed away, which was troublesome. In addition, since the water faucet is artificially opened, the water discharge amount becomes excessive or insufficient. Therefore, there is a problem that the drainage pipe is clogged because a required flow rate of water cannot be supplied to the disposer, and the water is excessively flown to wastefully consume the water.

The present invention has been made to solve the above problems, and provides a water supply device for a disposer capable of supplying a necessary flow rate of water to a disposer for a required time without wasting water. The purpose is to provide.

[0007]

In order to achieve the above object, the present invention provides an automatic valve at an appropriate position of a pipe to supply a fixed amount of water into a disposer for crushing raw garbage and the like. It is possible to prevent clogging of the drainage pipe of the disposer.

At least a timer for measuring the supply time of water into the disposer, a setting unit for setting a target opening of the automatic valve, and a detection unit for detecting an actual opening of the automatic valve, The automatic valve is provided with a comparison unit that compares the actual opening of the automatic valve with the target opening of the automatic valve set by the setting unit, and the automatic valve is a valve body and at least the detection unit, the comparison unit, and When a controller having an actuator having a motor for opening and closing the valve body is connected to the automatic valve and the disposer, and a controller having at least the timer and the setting unit is connected, before and after the disposer is started and stopped. It is possible to supply water, and it is possible to supply the optimal flow rate of water in each supply time into the disposer.

Further, since the disposer is provided with a lid switch for turning the switch on and off by opening and closing the lid, the disposer does not operate when the lid is opened, and the hand may be put in the hands while operating, It is safe because it doesn't lose its kind. Further, when an external switch is connected to the controller, it is possible to wash the tableware and to crush the garbage produced by the washing.

An embodiment of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a schematic diagram showing a configuration of an embodiment of a water supply device for a disposer, FIG. 2 is a block diagram showing a circuit configuration of the device, and FIG. 3 is a flowchart showing an operation of the disposer water supply device. In the figure, 1 is a sink, 2 is installed under the sink, a disposer for crushing raw garbage generated during cooking, 3 is a faucet, and an automatic valve 5 is installed at an appropriate position of the pipe 4 to discharge water, Stop water. Reference numeral 6 is a controller for controlling the disposer 2 and the automatic valve 5, respectively. The controller 6 is connected to the disposer 2 and the automatic valve 5, respectively. And 7 is an external switch.

The disposer 2 in this embodiment is for rotating a horizontally mounted rotary table with a blade by a motor 2a installed in a cylindrical container to pulverize the raw garbage packed inside, and a lid (not shown). Open / close (ON / OFF of lid switch 2b) or ON / OFF of external switch 7
With this, the device can be started and stopped. It should be noted that both the lid switch 2b and the external switch 7 do not necessarily have to be provided, and may be appropriately selected according to the usage situation.

The controller 6 includes a setting unit 6a for setting a target opening of the automatic valve 5 and a starter of the disposer 2,
The timer 6b measures the water supply time after the stop and the operation time of the disposer 2, and a relay T1, a relay T2 and a relay T3 connected to the timer 6b. The setting unit 6a in the present embodiment sets the target opening degree of the automatic valve 5 by varying and setting the resistance value between 0 and 135Ω according to the target opening degree. In this case, the resistance value is 0Ω, the automatic valve 5 is fully closed, and the resistance value is 135
Fully open with Ω. Although not shown, a method of setting a value other than the resistance value, such as a method of setting a voltage value (1 to 5 V) or a current value (4 to 20 mA) according to the target opening degree, is arbitrary depending on the implementation.

The lid switch 2b of the disposer 2
And the external switch 7 is the timer 6b of the controller 6.
Motor 2a of the disposer 2 is connected to the contact T1.
And to the power supply via a contact T2. Also,
The setting unit 6a of the controller 6 is connected to the actuator 5b of the automatic valve 5 via a contact T31, and is also grounded via a contact T32.

As the automatic valve 5, a valve body 5a having an actuator 5b capable of controlling rotation is used. For example, the valve body 5a is a butterfly valve or a ball valve, and the actuator 5b is an electric actuator. To be

As shown in FIG. 2, the actuator of this embodiment includes 5b, a detector 51, converters 52 and 53,
A potentiometer or the like is used as the detection unit 51 that is configured by the comparison unit 54, the amplifier 55, and the motor 56, and detects the actual opening degree of the automatic valve 5.
A resistance value corresponding to the actual valve opening is detected from the rotation angle of the shaft of the motor 56 by the (hereinafter, potentiometer), and the resistance value is converted into a voltage value (actually measured voltage) by the conversion unit 53, and the controller 6 The resistance value set by the setting unit 6a is converted into a voltage value (set voltage) by the conversion unit 52. Then, the measured voltage and the set voltage are compared by the comparison unit 54 to calculate the deviation voltage, the deviation voltage is amplified by the amplifier 55 and added to the motor 56, and the motor 56 rotates forward and backward according to the amplified deviation voltage. Then, the opening degree of the valve body 5a is adjusted.

The actuator used for the automatic valve 5 is not limited to the actuator 5b described above, and can be appropriately selected according to the conditions. For example, a flow rate sensor may be installed in the pipe to measure the flow rate of water, and the motor 56 may be rotated according to the measured flow rate. The setting unit 6a and the timer 6b provided in the controller 6 may be provided in the actuator 5b. On the contrary, the conversion units 52 and 53, the comparison unit 54, the amplifier 55 and the like may be provided in the controller 6.

The operation when the lid switch 2b of the disposer 2 is used will be described below with reference to FIG. First,
When garbage is packed in the disposer 2 and the lid is closed, the lid switch 2b is turned on, the timer 6b is activated, and the relay T
1, relay T2 and relay T3 are turned on. As a result, the contact T1 is opened, the contact T2 is closed, the contact T31 is closed, and the contact T32 is opened.
The resistance value set by the setting unit 6a of the controller 6 is transmitted to 2. Then, the converter 52 converts the transmitted resistance value into a voltage value (set voltage), and at the same time, the valve body 5a
The opening of is detected by the potentiometer 51 as a resistance value,
This resistance value is converted into a voltage value (measured voltage) by the conversion unit 53, and the deviation between the set voltage and the measured voltage is calculated by the comparison unit 54. Further, the deviation voltage is amplified by the amplifier 55 and applied to the motor 56, the opening is adjusted until the set voltage and the actual voltage become equal, and a fixed amount of water is spouted from the faucet portion 3 into the disposer 2. Water supply (water supply before disposer startup) is started.

When the relay T1 is turned off and the contact T1 is closed 3 seconds after the supply is started (3 seconds after the timer 6b is operated), the contact T1 and the contact T2 are closed and the motor 2a of the disposer 2 is closed.
A voltage is applied to the motor 2a, the motor 2a starts rotating, and the food waste packed in the disposer 2 is crushed.

After 30 seconds have passed since the disposer 2 was started (30 seconds after the relay T1 was turned off), the relay T2 was turned off, the contact T2 was opened, the motor 2a of the disposer 2 was stopped, and the crushing process of the garbage was completed.

After 20 seconds have passed since the motor 2a was stopped (20 seconds after the relay T2 was turned off), the relay T3 was turned off and the contact T31 was turned off.
Is opened, the contact T32 is closed, and the setting portion 6a is grounded. Then, the signal of the resistance value 0Ω is transmitted from the setting unit 6a to the actuator 5b, the actuator 5b fully closes the automatic valve 5, and the supply of water into the disposer 2 (water supply after the disposer is stopped) is completed.

When the lid of the disposer 2 is opened in the middle of the process, the timer 6b turns off the relay T2, the motor 2a of the disposer 2 is urgently stopped, and the crushing of garbage is forcibly terminated.

Therefore, by simply packing the garbage in the disposer 2 and closing the lid, a certain amount of water can be supplied to the disposer 2 for a predetermined time, and the garbage can be crushed without clogging the drain pipe. Further, since the disposer 2 does not operate unless the lid is closed, the disposer 2 is not broken by dropping a spoon or the like into the disposer 2. Further, it is safe to prevent an unexpected situation such as accidentally putting a hand.

When the external switch 7 is used, the opening and closing of the lid and the operation of the disposer 2 are irrelevant, and the external switch 7 is turned on even when the lid is open, so that the water supply before starting the disposer and the disposer are performed. Two
Can be started. Also, set the external switch 7 to O
By performing FF, the operation of the disposer 2 can be stopped and water can be supplied after the disposer is stopped.

In this case, since the disposer 2 can be operated with the lid open, it is possible to crush the garbage successively produced by washing the dishes, etc., each time.
