Abstract

PROBLEM TO BE SOLVED: To prevent breeding of miscellaneous bacteria in a drain pipe of a spittoon and preclude discharge of malodor from the drain pipe. SOLUTION: A washing water circuit 11 for spittoon spouts the washing water to the spittoon 3 to wash it. Ozone generated by an ozone generator 20 is included in the washing water circuit 11, and therewith the spittoon 3 is washed. Because ozone water flows in the drain pipe, there is no risk that miscellaneous bacteria propagate in the pipe.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a block diagram of the main part of a dental treatment unit according to the present invention, in which 3 is a spitton and 11 is a spitton cleaning water supply circuit for supplying water for cleaning the spitton 3. , 12 is a solenoid valve, 15 is a drain pipe,
As is well known, the electromagnetic valve 12 is opened to discharge the washing water into the spitton 3 to wash the spitton 3, and the dirty water after washing is discharged through the drain pipe 15 as described above. In this way, since wastewater is made to flow through the drain pipe 15, various bacteria propagate inside the drain pipe 15 and give off a bad odor.

According to the present invention, ozone is mixed in the spitton cleaning water supplied to the spitton 3 in order to prevent the propagation of various bacteria as described above and to prevent the release of a bad odor, and the spitton is washed with this ozone-mixed water. In FIG. 1, 20 is a well-known, for example, silent discharge,
Ozone generators by electrolysis, 21, 22 are solenoid valves,
Reference numeral 23 is a pressure reducing valve. Ozone (O ₃ ) generated by the ozone generator 20 is opened by the venturi effect in the cleaning water supply pipe 11 when the electromagnetic valve 21 is opened in synchronization with the electromagnetic valve 12 during the spittoon cleaning. Suctioned into the wash water supply pipe,
Mixed with wash water. If the connection portion of the cleaning water supply pipe 11 to the ozone supply pipe is made thin in order to increase the Venturi effect, the pressure becomes lower at the thinned portion (constricted portion), which is more effective. In addition, ozone can be mixed into the Spitton wash water.

As described above, the ozone generated by the ozone generator can be mixed into the spitton cleaning water by utilizing the Venturi effect of the cleaning water supply pipe.
It can also be effectively mixed with compressed air generated by a compressor that the dental treatment unit comprises (as a source of compressed air such as an air turbine). That is, in FIG. 1, the solenoid valve 22 is opened in synchronism with the solenoid valves 12 and 21, and the air of the compressed air source is adjusted to an appropriate pressure via the solenoid valve 22 and the pressure reducing valve 23 (that is, mixed with the spittoon wash water). The ozone generated in the ozone generator 20 is mixed into the spitton cleaning water through the electromagnetic valve 21 by supplying compressed ozone to the ozone generator 20 so that the amount of ozone is adjusted to an appropriate value. You may do it.

FIG. 2 is a main part configuration diagram for explaining another embodiment of the present invention (the invention of claim 5).
The ozone generated by the ozone generator 20 is mixed with gargle water so that the ozone-mixed water gargles the oral cavity. By doing so, sterilization of the oral cavity can be performed at the same time. . In FIG. 2, the solenoid valves 31, 32 and the pressure reducing valve 33 are the solenoid valves 2 shown in FIG.
Since the operation of the pressure reducing valve 23 is the same as that of the pressure reducing valve 23, the description thereof will be omitted here. Further, in FIG. 2, an example is shown in which the ozone generator is the same as the ozone generator for the spittoon cleaning water, but these may be separate, and further, a syringe or the like. It will be readily understood that the present invention may be applied to the water circuit of dental care instruments such that the water used in these instruments may be mixed with ozone.

In the above, the example in which the ozone (gas) generated by the ozone generator 20 is caused to flow into the water circuit used in the dental treatment unit has been described, but the ozone generator 20 generates the ozone. Ozone water may be produced using ozone, and this ozone water may be mixed with the water in the various water circuits of the dental treatment unit as described above. Since it dissolves in the interior, it does not generate ozone odor, and especially when ozone water is used in the water circuit of various instruments such as for spraying syringes, cooling water for micro engines, air turbines, etc. It is very easy to use because there are no bubbles mixed in.

Further, according to the above-mentioned embodiment, the dental treatment unit must be equipped with an ozone generator. For example, if ozone water in a tank is prepared or purchased,
The ozone water tank may be detachably attached to the dental treatment unit, and the ozone water in the tank may be mixed with water in various water circuits of the dental treatment unit and used as described above. .

[0021]

As is apparent from the above description, according to the present invention, in the dental treatment unit, since ozone-mixed water is made to flow into the drain pipe of the spitton, various bacteria are propagated in the drain pipe. Therefore, it is possible to maintain a very hygienic medical environment without releasing a bad odor from the drain pipe.
