Description

[Detailed Description of the Invention] <Industrial Application Field> Is this invention a diss? - This invention relates to an automatic water supply device and its control method, and particularly relates to a technique for preventing clogging of a discharge pipe. O <Prior art> A conventional disposer is shown in FIGS. 3(a) and 3(b).

In FIG. 3(a), 1 is a faucet, 2 is a drain, 3 is a disposer provided at the bottom of the sink 2, and 4 is a discharge pipe connected to the disposer 3, which is connected to a sewer pipe. 5 is a power switch that turns the disposer 3 ON and OFF-i.

In FIG. 3(b), 6 is a connecting member 5 that connects the sink 2 (see FIG. 3(a)) and the disposer 3 in a watertight manner.
m is the aperture. 7 is a hollow body, and the 95th section is a processing chamber 8. Also, a conch 7a protrudes from the upper part of the outer surface. 9 is directly attached to the shaft of a turntable driving motor installed in the processing chamber 8 . 10 is a rotating piece fixed to the turntable 9. Reference numeral 11 denotes a fixed blade fixedly installed on the peripheral side of the processing chamber 8 near the turntable.

121d1 This is an ergo connected to the discharge port 8a provided on the side of the processing chamber 8, and the discharge pipe 4 (see Fig. 3 (,))
Connect to. 13 is the drive motor storage section.The operation of this device will be explained.

First, the faucet 1 is opened to let water flow, and the power switch 5 is turned on to operate the drive motor of the disposer 3.

Then, the object to be processed, such as cooking scraps, is introduced into the processing chamber 8 through the opening of the connecting member 6. The object to be processed is urged against the side surface of the processing chamber 8 by the rotational force of the tar/table 90, and crushed by the rotating piece JO and the fixed blade 1. The material to be sufficiently pulverized flows out from the outlet 8a together with running water, and is discharged to the sewer pipe via the discharge pipe 4.

After processing all the objects to be processed, turn on the power switch 5'f:
: Turn off and close faucet 1.

<Problems to be Solved by the Invention> As mentioned above, when using a disposer, it was necessary to flush water. If the water is used without flushing or if the amount is insufficient even after flushing, the treated material will remain at the discharge port 8a or the discharge pipe 4, etc. Once this residue dries and sticks to the discharge pipe 4, etc., it becomes difficult to remove even with water and gold slurry. If this happens, the residue stuck to the disk becomes a resistance when the disk I-D is used next time, and more waste remains, eventually leading to a situation where the discharge pipe 4 etc. are clogged. Even if clogging has not yet occurred, a foul odor will always be present in the vicinity of 7/ri2.

In order to prevent such a situation, one should always make sure to flush water when using a disposer, but this is not always enforced. This is due to the fact that water supply, power switch, and turning on the TE5 were performed independently, and the operation was troublesome because two places had to be operated, and it was easy to forget. Another reason is that users are psychologically reluctant to pour tap water directly from the faucet I into the opening 6a at the bottom of the faucet 2 without using it for visible purposes such as washing dishes. There is a tendency for people to end up not supplying water, or even if they do supply water, the amount is often insufficient. In particular, when there were many children to be treated, the amount of water supplied tended to be insufficient.

Means for Solving the Problems> The present invention has been made in order to solve the above problems.

The automatic water supply system of the first aspect of the invention is such that a water supply pipe is connected to a processing chamber, and a valve that opens and closes in conjunction with the operation of a drive motor is disposed in the water supply pipe.

A second invention is an invention of a control method for the automatic water supply device of a disposer according to the first invention, in which the valve is opened with the start of the drive motor to start water supply, and the water supply is started after the drive motor has stopped. This closes the valve and stops the water supply.

Function> The automatic water supply device for a disposer of the first invention opens the valve of the water supply pipe in conjunction with the activation of the drive motor of the disposer,
The valve closes in conjunction with the stop of the drive motor. This automatically supplies water when the disposer operates.

The second invention is the above-mentioned automatic water supply device for dissolving water, which starts water supply when the drive motor starts, and completely stops the water supply with a delay when the drive motor stops. This ensures that the discharge is carried out reliably.

<Example> FIGS. 1(a) and 1(b) show an embodiment of the first invention.

In FIG. 1(a), the faucet 11, the drain 2, the disposer 3, the discharge pipe 4, and the power switch 5 are the same as those in FIG. 3(,), and detailed explanation thereof will be omitted. 14th floor, faucet 1
This is a water supply pipe connected to the pipe of the disposer 3 and the processing chamber of the disposer 3, which will be described later. 15 is a solenoid valve attached to this water supply pipe 14, and is connected to the power switch 5.

In FIG. 1(b), the connecting member 6, its opening 6az hollow body 7, processing chamber 8, tar 7 table 9, rotating piece 10, fixed blade 11. The elbow 12 and the one-stroke motor storage section I3 are the same as those shown in FIG. 3(b), and detailed description thereof will be omitted. Reference numeral 7a denotes a base formed protruding from the upper part of the outer surface of the hollow body 7. In this embodiment, the holes 7a and 7a are punctured to serve as a connecting portion for piping the water supply pipe I4 to the processing chamber 8.

The entire operation of this device will be explained.

First, turn on the power switch 5. Then, the drive motor starts and the turntable 9 begins to rotate, and the solenoid valve 15 opens to start supplying water from the water supply pipe I4 into the processing chamber 8. Then, as in the conventional case, objects to be processed, such as cooking scraps, are introduced into the processing chamber 8 through the opening 6a. turntable 9
The material to be treated is crushed by the rotational force of the pump and discharged from the outlet 8a together with the water flowing from the water supply pipe I4.

After processing all the objects to be processed, the power switch 5 is turned off. When the drive motor stops, the solenoid valve 15 closes and the water supply stops.

Although the drive motor and the solenoid valve I5 are operated simultaneously in this embodiment, they may also be operated with a slight time lag.

Next, as an embodiment of the method for controlling the automatic water supply system for a disposer according to the second invention, an example of application to the automatic water supply system for a disposer shown in FIG. 1 will be described.

This embodiment is based on the disk shown in FIG. - The automatic water supply device of the present invention has a control circuit shown in FIG.

In FIG. 2, I6 is an input terminal connected to an AC power source. The alternate type switch SW is the power switch 5 in FIG. Relays R1 to R7 are connected to terminal 1
It is connected in series with the switch SW between 6 and 16. A resistor R and a capacitor C are connected in parallel to relay R2. SQL is a solenoid valve I5 in FIG. 11(a), and is connected in series with a contact r2 of a relay R2 between terminals 16 and 16. Both terminals of the drive motor M are contacts of the relay R1'! -1" I-2 to terminal 16.16.

This operation will be explained.

When switch SW (power switch 5) is turned on, relays R,,R, are energized and contacts rI-1'r12+r2
becomes ON. As a result, solenoid valve 5QL (solenoid valve I5)
and the drive motor M operates. At the same time, the CoC stores electricity.

When the switch SW is turned off, the relay R1 is released and the contact '+-1'' I-2 is turned off.

However, relay R2 continues to be ON due to power being supplied by the capacitor, so contact ``2'' continues to be ON and solenoid valve SOL continues to operate until the capacity of the capacitor is exhausted and relay R2 is released.

This operation causes the solenoid valve SQL to turn the switch 5WOFF'
It will continue to operate for a predetermined period of time. This time can be set as necessary, but in this embodiment it is set to 2 to 3 minutes.

In addition, as another aspect, it is also possible to use a relay with a built-in delay recovery mechanism in the relay R2. In addition, a delay circuit using a semiconductor device or the like may also be used.

<Effects of the Invention> As explained above, the automatic water supply device for the disposer of the first invention automatically supplies water to the processing chamber in conjunction with the drive motor, so that there is no residual accumulation of processed materials or It is possible to prevent clogging of discharge pipes and the like due to processed materials. Furthermore, it is possible to prevent the occurrence of bad odors due to the residue.

Further, in the second invention, the number of stops of all drive motors of the automatic water supply device of the disposer of the first invention is controlled so as to maintain water resistance for a predetermined period of time. It is possible to more reliably prevent the discharge pipe etc. from being clogged with objects.
