DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an automatic dental water supply device according to the present invention will be described below with reference to the drawings. FIG. 1 is an external view, and 1 is a known spittoon bowl (hereinafter, simply referred to as a bowl), and a bowl cleaning switch operated when supplying cleaning water is provided on the front surface. 2 is a water supply device for supplying gargling water fixed to the bowl 1 directly or in the vicinity thereof,
Reference numeral 3 is a known cup holder installed near the water supply device 2 for storing a disposable cup 4 such as a paper cup.

The water supply device 2 has a housing 2a formed at the bottom thereof so that the cup 4 cannot be placed therein, a water inlet 2b located above the housing 2a for supplying mouthwash water to the cup 4 and the housing 2a. An optical sensor 2c, which sends out an electric signal for detecting that the cup 4 installed near the water injection port 2b and the bottom is approaching, and discharges the cleaning water mixed with the chemical solution for cleaning the inside of the bowl 1. 2d for cleaning water.

Next, the circuit of the first embodiment for supplying the gargle water from the water injection port 2b and draining the cleaning water from the cleaning water port 2d will be described with reference to FIG. In the figure, thick lines are water lines, alternate long and short dash lines are electric lines, and thin lines are air lines. Further, the same reference numerals as in FIG.

Reference numeral 5 is a control circuit which is a timer circuit for energizing the solenoid valve 6 for a certain period of time (time until the cup 4 is filled with water) when a signal from the optical sensor 2c is input. Then, the solenoid valve 6 is opened while energized to allow air to pass therethrough.

Reference numeral 7 is a cup water supply valve which opens the valve of the solenoid valve 6 and opens the valve when air is supplied to allow water to pass therethrough. Reference numeral 8 denotes air when the bowl cleaning switch 1a provided in the bowl 1 is opened. Is supplied, the valve is opened to allow water to pass through, a bowl cleaning valve, 9 is disinfectant,
It is a chemical solution tank that stores a colored chemical solution having a deodorizing effect.

Next, to explain the operation based on the above-mentioned structure, when the patient who has finished the treatment takes out the cup 4 from the cup holder 3 and brings it to the vicinity of the optical sensor 2c of the water supply device 2, the light is emitted. The sensor 2c detects the cup and outputs a signal to the control circuit 5. The control circuit 5 receiving this detection signal sends an output to the solenoid valve 6 for a certain period of time, so that the solenoid valve 6 opens the valve.

When the solenoid valve 6 is opened, the air from the air line is supplied to the cup water supply valve 7,
The cup water supply valve 7 is opened to supply mouthwash water from the water line into the cup 4 from the water inlet 2b through the pipe 7a. Then, after a lapse of time when the water in the cup 4 is almost full, the supply of electric power from the control circuit 5 to the solenoid valve 6 is stopped. As a result, the valve of the solenoid valve 6 is closed, so that the cup water supply valve 7 is also closed and the supply of mouthwash water to the cup 4 is stopped.

When the patient himself or his or her dentist or assistant operates the bowl cleaning switch 1a installed on the bowl 1, air from the air line is supplied to the bowl cleaning valve 8, so that the bowl cleaning valve 8 is opened. Then, the water from the water line is drained from the washing water port 2d through the pipe 8a and the mixer 10.

When the wash water is drained to the bowl 1, the inside of the pipe 9a from the chemical liquid tank 9 connected to the pipe 8a becomes a negative pressure due to the water flow of the wash water, so the chemical liquid is passed through the pipe 9a. The chemicals in the tank 9 are sucked, mixed in the mixer 10 and discharged from the cleaning water port 2d. Therefore, the wash water of the color colored in the chemical liquid flows into the bowl 1, and the patient can confirm that the bowl 1 is washed.

Next, another embodiment of FIG. 3 will be described. The same reference numerals as those in the embodiment of FIG. 2 described above indicate the same members, and a description thereof will be omitted. The difference from the above-described embodiment is that the washing water for the bowl 1 is operated by operating the bowl washing switch 1a, whereas the present embodiment is performed in conjunction with the water supply to the gargle water cup 4. It is designed to drain water.

In the present embodiment, 12 is the control circuit 5
The second control circuit, which is a timer circuit, which sends an output to the solenoid valve 6 in response to a detection signal from the optical sensor 2c, and at the same time sends an output for a fixed time (a time longer than the time for supplying water to the cup 4) , 13 is the control circuit 1
This is a solenoid valve that is excited by the output from the valve 2 and opens the valve.

To explain the operation of this embodiment, the mouth water supply to the cup 4 is the same as that of the embodiment shown in FIG. When the control circuit 5 receives the detection signal from the optical sensor 2c, the control circuit 5 sends a signal to the control circuit 12, so that the control circuit 12 sends an output to the solenoid valve 13 for a certain period of time.

Therefore, the solenoid valve 13 is excited to open the valve, so that the air from the air line is supplied to the bowl cleaning valve 8 to open the bowl cleaning valve 8 and the water from the water line to the pipe 8a, It is drained from the washing water port 2d via the mixer 10. As a result, similar to the above, the chemical liquid is sucked from the chemical liquid tank 9 and discharged into the bowl 1 together with the wash water.

Next, another embodiment of FIG. 4 will be described. The same reference numerals as those in the embodiment of FIG. 3 described above indicate the same members, and the description thereof will be omitted. The difference from the embodiment of FIG. 3 described above is that the time for discharging the cleaning water is controlled by the control circuit 12, whereas in this embodiment the time for discharging the cleaning water is controlled by the air delay circuit 14. It is that you are.

That is, the air delay circuit 14 includes the solenoid valve 6
When air is supplied from the valve opened by, the air is gradually accumulated while being discharged. And
When the air from the solenoid valve 6 is shut off, the accumulated air is gradually discharged. The air delay circuit 14 is connected to the bowl cleaning valve 8 via the check valve 15.
It is connected to the.

To explain the operation of this embodiment, the mouth water supply to the cup 4 is the same as that of the embodiment shown in FIG. As in the above-described operation, when the solenoid valve 6 is energized and the valve is opened, air is supplied to the air delay circuit 14, so that the air delay circuit 1
4 supplies air to the bowl cleaning valve 8 via the check valve 15.

As a result, the bowl cleaning valve 8 is opened and the cleaning water from the water line is discharged from the cleaning water port 2d, so that the chemical solution is also sucked and discharged together. Further, the air delay circuit 14 gradually stores the air supplied from the valve of the solenoid valve 6. Then, when the control circuit 5 causes the solenoid valve 6 to be de-energized and the valve to be closed, the air supply to the air delay circuit 14 is shut off.

Here, since the air delay circuit 14 gradually discharges the air accumulated so far, the air is continuously supplied to the bowl cleaning valve 8, and therefore the cleaning water is continuously discharged. Be seen. Then, when the amount of air accumulated in the air delay circuit 14 decreases, the amount of air to the bowl cleaning valve 8 also decreases, so that the bowl cleaning valve 8 is closed and drainage of the cleaning water from the water line is stopped.
The cleaning of the bowl 1 is completed after a lapse of a certain time from the irrigation water supply.

In this embodiment, the above-mentioned FIG.
As in the above embodiment, the cleaning water can be drained into the bowl 1 by operating the bowl cleaning switch 1a.
