[0018]
A case will be described in which the water circuit is sterilized and washed with sterilized water at the end of the treatment work, and then the sterilized water is washed away with the wash water, and the water circuit is emptied and dried with drying air.
First, the sterilization process of the water circuit with sterilized water will be described.
First, wash water is introduced as shown by an inflow direction arrow 44, and the water circuit switching control unit 49 closes the water path opening / closing electromagnetic valve 45 for the cleaning water, and opens the water path opening / closing electromagnetic valve 46 for the sterilizing water generator 50 to sterilize. Produce water.
This sterilized water is sent out by the feed water pump 48 as indicated by the flow direction arrow 51 of the drain water main pipe, and the discharge tube group 34, the base 36a of the water feed tube, and the cup water feed pipe of the cup water feed water circuit 63. Each of the base 64a passes through the branch discharge pipe water channel as indicated by the flow direction arrow 52 of the branch discharge pipe water channel, and the discharge tubes 11d to 16d extended from the water supply port and the discharge tube 36d extended from the water supply port. The water is discharged from the cup water supply pipe 60 to the cup water supply receiving port 61 connected to the water circuit processing unit 19 via the scattering prevention connecting pipe 39 and stored in the storage tank 21 of the water circuit processing unit 19.
[0019]
Then, from the relationship between the water level detection 57 of the water circuit switching control unit 49 and the start elapsed time of the water supply pump 48 (not shown), the water path opening / closing electromagnetic valve 70 is opened, the drainage suction pump 55 is operated, From the connection end of the suction tube (the tube connection end 17b of the vacuum syringe and the connection end 18b of the saliva ejector tube),
The stored waste water is sucked, and the waste water passes through the elongated suction tubes 17d and 18d, and the base of the suction device tube (vacuum syringe tube) as indicated by the flow direction arrow 54 of the suction water channel main pipe. The suction water is discharged from the suction tube group 33 of the base portion 17a and the saliva ejector tube base portion 18a) in the discharge direction 56 to the external drain pipe.
At this time, the drying air line opening / closing solenoid valve 71 is closed.
By flowing the sterilizing water for a predetermined time as described above, the inside of each instrument water circuit is sterilized and washed.
On the other hand, the sterilized water branched as indicated by the flow direction arrow 66 from the main pipe of the drainage water flows directly into the water circuit 65 for the spitton washing from the spitton washing pipe 25 and opens the open / close electromagnetic valve 74 for opening and closing the drainage. As shown, the discharge direction 59 to the external drain pipe is discharged, merged with the discharge direction 56 of the suction water to the external drain pipe, and discharged to the merge drain pipe 78.
In the above case, it is assumed that the exhaust opening / closing solenoid valve 75 is closed.
[0020]
Next, the process of cleaning the water circuit with cleaning water will be described.
After the sterilizing water is discharged, the sterilizing water side water path opening / closing solenoid valve 46 is closed, and the cleaning water side water path opening / closing electromagnetic valve 45 is opened. Thereafter, the water circuit is washed in the same process as described above. Water is allowed to flow for a predetermined time, and the sterilizing water is washed away to prevent corrosion and deterioration due to oxidation in the water channel.
The check valve 47 prevents mixing of the sterilizing water and the washing water at the time of switching, and the check valve 62 includes the water circuit processing unit 19, the water circuit 63 for the cup water supply, and the water circuit for the spitton washing. Mixing with 65 is prevented.
Then, after a predetermined time has elapsed, the water circuit opening / closing electromagnetic valve 45 is closed, and the stored water in the storage tank 21 is evacuated by continuously operating the drain suction pump 55 to perform suction drainage.
[0021]
Next, the process of emptying the water circuit with drying air and drying it will be described.
By the above process, the water circuit becomes only the remaining washing water. However, in the drying air process, the water channel opening / closing solenoid valves 45 and 46 are closed and sucked together under the control of the water circuit switching control unit 49. The pump 55 is also stopped.
The drainage path opening / closing solenoid valve 70 is closed, and the drying air opening / closing solenoid valve 71 is opened.
When the drying air compressor 67 is operated by the water circuit switching control unit 49 in the above-described state, the drying air is supplied to the discharge tube group 34, the water supply tube base 36a, and the cup water supply of the cup water supply water circuit 63. Each of the pipe bases 64a passes through the branch discharge pipe water channel as indicated by the flow direction arrow 52, and the discharge tubes 36d extended from the extended discharge tubes 11d to 16d and the water supply tube base 36a. And, it is discharged from the cup water supply receiving port 61 connected to the water circuit processing unit 19 via the cup water supply pipe 60 and discharged and stored in the lower tank 21 of the water circuit processing unit 19 (in the tank in the figure). Residual water is replaced by drying air (not shown). However, the stored drying air is not sealed.
[0022]
Then, the air suction pump 73 for drying (not shown) is operated in relation to the elapsed time for supplying the drying air (not shown), and the suction tube connection end (the tube connection end 17b of the vacuum syringe and the connection of the saliva ejector tube). The stored drying air is sucked from the end 18 b), and the drying air flows through the suction tubes 17 d and 18 d that have been extended, flows through the drying air pipe 72, and is exhausted to the exhaust pipe 77. Is done.
By flowing the drying air for a predetermined time as described above, the interior of the water circuit of each instrument is emptied and dried.
[0023]
On the other hand, the drying air branched as shown by the flow direction arrow 66 in the water circuit 65 for spitton cleaning is directly ejected from the spitton cleaning pipe 25 to the water circuit 65 for spitton cleaning, but the spitton drain hole 80 (FIG. 3). ), The air cannot be sealed. At this time, residual water in the trap of the water circuit 65 for spit-on cleaning is also removed by the suction.
In the above case, the drain opening / closing solenoid valve 74 is closed and the exhaust opening / closing solenoid valve 75 is controlled to open. Accordingly, the drying air suction pump 73 joins the drying air pipe 72 and exhausts the drying air to the exhaust pipe 77 as in the exhaust direction 76 to the external exhaust pipe of Spitton.
The interior of the Spitton water circuit is emptied and dried as described above.
[0024]
In addition, when the air for drying is flowed to each water circuit and the interior is emptied and dried, the air for drying is heated and supplied more quickly, and further sterilization is added. can do.

58 is an arrow indicating the outflow direction of the overflow channel, and 79 is an open / close solenoid valve for the overflow channel.
In this block diagram, what is different from the operation of FIG. 7 is that an overflow discharge port 24 is provided in the storage tank 21 (FIGS. 6- (B) and (C)).
In the storage tank 21, drainage that exceeds a certain water level (height 43 of the central convex portion in FIG. 6- (c)) passes through the overflow channel open / close solenoid valve 79, and enters the overflow channel from the overflow outlet 24. It flows out as indicated by an outflow direction arrow 58, joins in the discharge direction 56 to the external drain pipe of the suction water, and is discharged.
The overflow flow path opening / closing electromagnetic valve 79 is controlled to be opened when the sterilizing water and the washing water are drained and closed when the drying air is operated.
