By operating the cleaning liquid pump 18, the cleaning liquid of the acidic water previously stored in the cleaning liquid tank 11 is sent to the cleaning nozzle 6 and the pipe line liquid-sending connector 8 through the cleaning liquid supply pipe 16, and the nozzle 6 is removed from the outside of the endoscope 4. The surface is cleaned by spraying a cleaning liquid, and further, the inside of the conduit of the endoscope 4 is cleaned from the conduit liquid feeding connector 8 through the adapter tube. At this time, the second switching valve 22 connects the discharge introduction pipe 21 to the second discharge pipe 23.
Since the discharge pump 24 is operated, the cleaning water that drops to the bottom of the cleaning tank 2 is sequentially discharged. Also, in conjunction with this, the above-mentioned discharge solenoid valve 19 opens to discharge caustic water, so that the caustic water is mixed with the cleaning water discharged from the cleaning liquid tank 11 and discharged through the first discharge pipe 17. Here, caustic water and acidic water are mixed and neutralized to return to normal water, so that the environment is not damaged.

Good. A caustic water drainage tank (not shown) is provided immediately after the discharge solenoid valve 19.
And a valve downstream of the caustic water drainage tank. Then, the discharge solenoid valve 19 is opened in association with the operation of the cleaning liquid pump 18, through which the caustic water in the cleaning liquid tank 11 is temporarily stored in the caustic water draining tank, and the opening of the valve is controlled to control the cleaning tank 2 from the cleaning tank 2. Discharge according to the cleaning water to be discharged,
The caustic water and the acidic water may be discharged at the same discharge timing and amount as much as possible, and may be neutralized during this discharge. In this washing process, the washing is performed by sequentially performing pre-washing with tap water, main washing with a detergent, and rinsing with tap water.

In this disinfecting step, after the cleaning water supply operation is stopped and the cleaning solution in the cleaning tank 2 is discharged, the second switching valve 22 is closed and the disinfectant solution pump 26 is operated to inject the disinfectant solution through the disinfectant solution supply pipe 25. The disinfecting liquid is supplied to the cleaning tank 2 from the cleaning nozzle 7. Then, the endoscope 4 is immersed in the disinfectant solution stored in the cleaning tank 2 and is supplied into the conduit of the endoscope 4 from the conduit liquid feeding connector 8 through the adapter tube. By maintaining the state in which the endoscope 4 is immersed in the disinfecting solution for a while, the outer surface of the endoscope 4 and the inside of the conduit thereof are both disinfected. When this disinfection is completed, the second switching valve 22 is switched to the side of the disinfectant solution tank 12, and the disinfectant solution is collected in the disinfectant solution tank 12 through the discharge introduction pipe 21. This completes a series of disinfection steps.

可能である。Then, a step of rinsing the disinfectant solution is performed. This rinsing process is the same as the above-mentioned cleaning process using only cleaning water without detergent. That is, the cleaning liquid pump 18 is operated, and the acidic water (rinsing water) having a pH of 2 to 3 previously stored in the cleaning liquid tank 11 is supplied to the cleaning liquid supply pipe 16
Through the cleaning nozzle 6 and the pipe line liquid feeding connector 8 to spray the washing liquid from the nozzle 6 onto the outer surface of the endoscope 4 for rinsing and washing. The inside of the conduit of the mirror 4 is rinsed and washed. At this time, the second switching valve 22 connects the discharge introduction pipe 21 to the second discharge pipe 23, and the discharge pump 2
Since 4 operates, the cleaning water that drops into the cleaning tank 2 is sequentially discharged. Further, the discharged cleaning water is combined with the caustic water discharged from the bath 34 on the cathode 35 side of the cleaning liquid tank 11 described above, and is discharged through the first discharge pipe 17. Here, the amounts of caustic water and acidic water that are discharged are approximately the same, so they are neutralized and returned to normal water. However,
Depending on the capacity of the cleaning liquid tank 11 and the like, it is possible to take out only the acidic water to a certain amount and use it for rinsing and cleaning.

であっても、雑菌が再び繁殖するようなことがない。Especially, in this rinsing step, the microorganisms in the tap water can be killed / removed by the antibacterial spectrum generated by the acidic water generated in the cleaning liquid tank 11. In addition to its bactericidal activity due to its acidity, it also exhibits a considerable antibacterial spectrum due to the activation of chlorine ions in tap water and the generation of ozone, albeit in a small amount. Therefore, there is no risk that the disinfected endoscope 4 will be contaminated again during rinsing. In addition, since no germs remain in the acidic water used for rinsing after cleaning and disinfecting, even if the subsequent drying is insufficient, the germs will not reproduce again.

The additive tank 40 contains an additive that increases conductivity of tap water to be electrolyzed, for example, sodium chloride (NaCl). Therefore, an amount of the additive that corresponds to the inflow amount of tap water supplied to the cleaning liquid tank 11 is added to the tap water. By thus adding the additive to the tap water supplied to the cleaning liquid tank 11, the conductivity of the tap water is increased, and efficient electrolysis can be performed.

効果が得られる。At the time of cleaning, the outlet for discharging caustic water generated in the tank 34 on the cathode 35 side in the cleaning liquid tank 11 is connected to the cleaning liquid supply pipe 16 and the anode 3
By setting the outlet for discharging the generated acidic water in the third side tank 32 to the first discharge pipe 17, the caustic water is used for cleaning. During the rinsing step, the outlet for discharging the acidic water generated in the tank 32 on the anode 33 side of the cleaning liquid tank 11 is used as the cleaning liquid supply pipe 1.
6 and the outlet for discharging caustic water is connected to the first discharge pipe 17. Then, rinsing is performed with acidic water. By doing this, since the washing step is performed using caustic water, the ability to remove proteins increases,
While a higher cleaning effect can be obtained, since the rinsing is performed with acidic water, the same effect as that of the first embodiment described above can be obtained.

The air supply conduit 51 of the endoscope 4 is connected at a branch portion 53 in the middle of the tank pressurizing conduit 52. The tip of the tank pressurizing pipe line 52 opens in the upper space of the water supply tank 54 without being immersed in the stored water 55. The branch portion 53 is installed in the upper space of the water supply tank 54. The tip of the water supply pipe 56 of the endoscope 4 is opened by being immersed in the stored water 55 of the water supply tank 54. The stored water 55 of the water supply tank 54 is pressurized through the tank pressurizing conduit 52 by an air supply pump attached to a light source device (not shown). By the air / water switching valve provided in the operation unit (not shown) of the endoscope 4, the tank pressurizing pipe line 52, the branch unit 5
3. Air is supplied through the path of the air supply conduit 51, and the stored water 55 of the water supply tank 54 is supplied through the water supply conduit 56 by shutting off the air supply conduit 51. Since the branch portion 53 is thus provided in the water supply tank 54, not in the main body of the endoscope 4, the configuration of the conduit in the main body of the endoscope 4 is simplified, and the endoscope 4 The cleaning property of is improved. Further, since the tank pressurizing pipe line 52 and the air supply pipe line 51 are connected through the branching portion 53, water is unlikely to enter the air supply pipe line 51 even if the water supply tank 54 falls over.
