  When the ON signal of the water supply line disinfection button 13d of the sub operation panel 13 is input, the control unit 70 supplies a driving signal to the chemical pump 65 to drive the chemical pump 65 (S11). At this time, the disinfecting liquid stored in the chemical liquid tank 58 is sucked up by the chemical liquid pump 65 from the suction filter 63 into the chemical liquid pipe 64 and flows into the cleaning / disinfecting tank 4 from the disinfecting liquid nozzle 23.

  And the control part 70 supplies a drive signal to the three-way solenoid valve 10, and drives the three-way solenoid valve 10 so that the water supply pipe line 9 and the water supply nozzle 24 may communicate (S12). After a while, the disinfecting liquid is stored in the cleaning / disinfecting tank 4, and when the water level reaches a predetermined level, the water level sensor 32 detects the predetermined water level of the disinfecting liquid, and the detection signal is supplied to the control unit 70 (S13). .

  Next, the controller 70 supplies a driving stop signal to the chemical pump 65 to stop the chemical pump 65, supplies a start signal to the channel pump 26 to drive the channel pump 26 (S14), and the CH solenoid valve 28. Is supplied with an open signal to open the CH solenoid valve 28 (S15). At this time, the disinfectant stored in the cleaning / disinfecting tank 4 is sent from the circulation port 56 to the circulation line 20 by the channel pump 26, passes through the channel line 21, passes through the channel block 27, the CH electromagnetic valve 28, and From the air / water supply / forceps port 33 through the check valve 29, the disinfection tube 75, the water supply line disinfection port 7, the water supply filter 17, the water supply line 9, and the three-way solenoid valve 10 again. It flows out into the washing / disinfecting tank 4. The disinfectant also flows into the case conduit 30 connected to the channel conduit 21 on the secondary side after passing through the channel block 27, and from the cleaning case 6 to the cleaning disinfecting tank 4 through the relief valve 36. To leak.

Thus, the disinfectant liquid disinfects the tank of the cleaning / disinfecting tank 4 at a predetermined water level stored in the cleaning / disinfecting tank 4, and circulates in the water supply line 9, the circulation line 20, and the channel line 21. To do. At this time, the disinfectant liquid does not flow into the alcohol conduit 41 and the air conduit 44 by the electromagnetic valve 43 and the check valve 47.

  Next, after a predetermined time has elapsed, the control unit 70 supplies a switching signal to the switching valve 57 and drives the switching valve 57 to the side of the chemical solution recovery line 61 (S16). Then, after a predetermined time elapses, the control unit 70 supplies a closing signal to the switching valve 57 to close the switching valve (S17), supplies a drive stop signal to the channel pump 26, and stops the channel pump 26 (S18). ). As a result, the disinfecting liquid stored in the cleaning / disinfecting tank 4 flows from the drain outlet 55 into the chemical recovery pipe 61 and is recovered in the chemical tank 58.

  Therefore, the endoscope cleaning / disinfecting apparatus 1 in which the water supply line disinfection program is selected and operated is stored in the cleaning / disinfecting tank 4 in the predetermined water level, in the water supply line 9, in the circulation line 20, and in the channel line 21. And the inside of the case conduit 30 can be surely sterilized. The routine performed by the control unit 70 from step S1 to step S18 described above is a water supply line disinfection step in the endoscope cleaning / disinfecting apparatus 1.

  In the water supply line disinfection process, the disinfectant stored in the cleaning / disinfecting tank 4 is heated by the heater 53 to the above-described appropriate temperature at which the disinfection effect can be most expected. At this time, the control unit 70 supplies a drive signal to the heater 53 based on the detection result from the temperature detection sensor 53a. That is, the heater 53 continues to heat the disinfectant solution to the appropriate temperature.

  Further, based on the detection result from the temperature detection sensor 53a, the control unit 70 stops the driving of the heater 53 when the disinfecting liquid reaches the appropriate temperature. Thereafter, when the temperature of the disinfecting liquid circulating in the apparatus decreases, the control unit 70 drives the heater 53 again based on the detection result of the temperature detection sensor 53a, so that the disinfecting liquid is in the proper state. Warmed to temperature. Thus, based on the detection result of the temperature detection sensor 53a, the disinfecting liquid stored in the cleaning / disinfecting tank 4 and circulating in the apparatus under the control of the driving / stopping of the heater 53 by the control unit 70 has the most disinfecting effect. It is kept at the expected proper temperature.

  After a sufficient time has elapsed for the disinfecting liquid to be collected in the chemical tank 58, the control unit 70 supplies an open signal to the water supply electromagnetic valve 15 to open the water supply electromagnetic valve 15 (S19). Thereby, the tap water which is the rinsing water from the water tap 5 flows into the water supply line 9 through the water supply hose 31 a and the water supply hose connection port 31. Then, the tap water passes through the water supply electromagnetic valve 15 and the check valve 16, is filtered by the water supply filter 17, flows to the water supply nozzle 24 side by the three-way electromagnetic valve 10, and flows out into the washing / disinfecting tank 4.

  When the tap water stored in the washing / disinfecting tank 4 reaches a predetermined water level, the water level sensor 32 detects it, and the detection signal is supplied to the control unit 70 (S20). And the control part 70 supplies a start signal to the channel pump 26, drives the channel pump 26 (S21), supplies a close signal to the water supply electromagnetic valve 15, and closes the water supply electromagnetic valve 15 (S22). Thus, the tap water in the cleaning / disinfecting tank 4 is sucked from the circulation port 56 by the channel pump 26 and flows into the channel line 21 through the circulation line 20, and the channel block 27, the CH electromagnetic valve 28 and the check valve. Washing and disinfection is performed again from each air / water supply / forceps port 33 through the valve 29 through the disinfection tube 75, the water supply line disinfection port 7, the water supply filter 17, the water supply line 9, and the three-way solenoid valve 10. It flows out into the tank 4. The tap water also flows into the case conduit 30 connected to the channel conduit 21 and flows out from the cleaning case 6 to the cleaning / disinfecting tank 4 through the relief valve 36.

  Thus, the tap water which is the rinsing water is rinsed in the tank of the cleaning / disinfecting tank 4 at a predetermined water level stored in the cleaning / disinfecting tank 4, and in the water supply line 9, the circulation line 20, and the channel line. It circulates in the inside of 21 and the inside of the case pipe line 30 and rinses the remaining disinfectant solution.

Then, after a predetermined time has elapsed, the control unit 70 supplies a switching signal to the switching valve 57 to drive the switching valve 57 toward the drainage pipe 59 (S23), and supplies a start signal to the drainage pump 60 to supply the drainage pump. 60 is driven (S60). Thus, the tap water stored in the cleaning / disinfecting tank 4 and circulating inside the apparatus is sucked into the drainage pipe 59 from the drain outlet 55 of the cleaning / disinfecting tank 4 through the switching valve 57 by the drain pump 60. , Flows out to the external drain.
After a predetermined time has elapsed, the control unit 70 supplies drive stop signals to the channel pump 26 and the drainage pump 60, respectively, stops driving the pumps 26 and 60 (S24), and ends all routines.

  Therefore, the endoscope cleaning / disinfecting apparatus 1 reliably ensures that the cleaning / disinfecting tank 4 in the predetermined water level, the water supply pipe 9, the circulation pipe 20, the channel pipe 21, and the case pipe 30 are in the tank. Rinsing and remaining disinfectant can be drained. The routine performed by the control unit 70 from step S19 to step S25 described above is a water supply line rinsing process in the endoscope cleaning / disinfecting apparatus 1.

  As a result of the above, the endoscope cleaning / disinfecting apparatus 1 according to the present embodiment is configured such that when the water supply line disinfection button 13d of the sub operation panel 13 is selected, the inside of the cleaning / disinfecting tank 4 at the predetermined water level, the water supply pipe The inside of the passage 9, the inside of the circulation pipe 20, the inside of the channel pipe 21, and the inside of the case pipe 30 can be surely disinfected, and the remaining disinfecting liquid can be rinsed and drained.

Next, when the user selects the all-pipe disinfection program with the all-pipe disinfection button 13e on the sub operation panel 13 and disinfects each pipe, the control unit 70 controls various pumps and each solenoid valve. An example of the operation flow will be described according to each step (S) of the flowchart of FIG.
In the following description of the flowchart of FIG. 1, in each routine performed by the control unit 70, Step 31 to Step 35, Step 39, Step 42 to Step 45, and Step 49 of FIG. Step 17, Step 19 to Step 22 and Step 24 are the same operations, and therefore their explanation is omitted or simplified.

  When the user selects and operates the all-pipe disinfection button 13e on the sub operation panel 13, the control unit 70 performs steps S31 to S35 in FIG. 10 in the same manner as steps S11 to S15 in FIG. 9 described above. Control operation of the pump and each solenoid valve.

  The disinfectant is sterilized in the washing / disinfecting tank 4 at a predetermined water level stored in the washing / disinfecting tank 4 by opening the CH electromagnetic valve 28 in step 35 by driving the channel pump 26 in step 34. At the same time, sterilization is performed while circulating in the water supply line 9, the circulation line 20, the channel line 21, and the case line 30.

  After a predetermined time has elapsed, the control unit 70 supplies a switching signal to the three-way solenoid valve 10 to drive the three-way solenoid valve 10 toward the fluid flow line 18 (S36), and supplies a drive stop signal to the channel pump 26. Then, the channel pump 26 is stopped, a start signal is supplied to the fluid pump 19, and the fluid pump 19 is driven (S37). As a result, the disinfecting liquid stored in the washing / disinfecting tank 4 is drawn from the water supply nozzle 24 by the suction of the flow pump 19, through the circulation port 56, through the circulation line 20, and into the flow line 18. It flows out again into the washing / disinfecting tank 4.

  Thus, the disinfecting liquid disinfects the inside of the washing / disinfecting tank 4 at a predetermined water level stored in the washing / disinfecting tank 4, and the inside of the water supply line 9, the circulation line 20 and the flowing liquid line 18. Disinfect while circulating.

  Next, after a predetermined time has elapsed, the control unit 70 supplies a switching signal to the switching valve 57 and drives the switching valve 57 to the side of the chemical solution recovery pipeline 61 (S38). Then, after a predetermined time has passed, the control unit 70 supplies a closing signal to the switching valve 57 and closes the switching valve 57 (S39), and supplies a driving stop signal to the fluid pump 19 to stop the fluid pump 19. (S40). As a result, the disinfecting liquid stored in the cleaning / disinfecting tank 4 flows from the drain outlet 55 into the chemical recovery pipe 61 and is recovered in the chemical tank 58.

  Accordingly, the endoscope cleaning / disinfecting apparatus 1 is provided in the cleaning / disinfecting tank 4 at a predetermined water level, in the water supply line 9, in the circulation line 20, in the channel line 21, in the flowing liquid line 18, and for the case. The inside of the pipe line 30 can be surely sterilized. The routine performed by the control unit 70 from step S31 to step S40 described above is an all-pipe disinfection step in the endoscope cleaning / disinfecting apparatus 1.

  After a sufficient predetermined time has elapsed for the disinfecting liquid to be collected in the chemical tank 58, the control unit 70 supplies a switching signal to the three-way solenoid valve 10 to drive the three-way solenoid valve 10 toward the water supply line 9. (S41), an open signal is supplied to the water supply electromagnetic valve 15 to open the water supply electromagnetic valve 15 (S42). Thereby, the tap water which is the rinsing water from the water tap 5 flows out from the water supply nozzle 24 into the washing / disinfecting tank 4.

  When the tap water stored in the washing / disinfecting tank 4 reaches a predetermined water level, the water level sensor 32 detects it, and the detection signal is supplied to the control unit 70 (S43). And the control part 70 supplies a starting signal to the channel pump 26, drives the channel pump 26 (S44), supplies a close signal to the water supply electromagnetic valve 15, and closes the water supply electromagnetic valve 15 (S45). Thus, the tap water which is the rinsing water in the cleaning / disinfecting tank 4 is rinsed in the tank of the cleaning / disinfecting tank 4 at a predetermined water level stored in the cleaning / disinfecting tank 4, and in the water supply line 9 and the circulation line. 20, the channel line 21 and the case line 30 are circulated to rinse the remaining disinfectant solution.

  After a predetermined time has elapsed, the control unit 70 supplies a switching signal to the three-way solenoid valve 10 to drive the three-way solenoid valve 10 to the fluid flow line 18 side (S46), and a drive stop signal to the channel pump 26. To stop the channel pump 26, supply a start signal to the fluid pump 19 and drive the fluid pump 19 (S47). Thus, the tap water which is the rinsing water is further rinsed in the tank of the cleaning / disinfecting tank 4 and the circulation line 20 at a predetermined water level stored in the cleaning / disinfecting tank 4, and mainly in the flowing liquid line 18. And rinse the remaining disinfectant solution.

After a predetermined time has elapsed, the control unit 70 supplies a switching signal to the switching valve 57, drives the switching valve 57 to the drain line 59 side (S48), supplies a start signal to the drain pump 60, and the drain pump 60. Is driven (S49). Thus, the tap water stored in the washing / disinfecting tank 4 and circulating inside the apparatus is sucked into the drainage pipe 59 from the draining port 55 of the washing / disinfecting tank 4 through the switching valve 57 by the drainage pump 60. , Flows out to the external drain.
After a predetermined time has elapsed, the control unit 70 supplies drive stop signals to the fluid pump 19 and the drainage pump 60, stops the pumps 19 and 60 (S50), and ends all routines.

  Accordingly, the endoscope cleaning / disinfecting apparatus 1 is provided in the cleaning / disinfecting tank 4 at a predetermined water level, in the water supply line 9, in the circulation line 20, in the channel line 21, in the flowing liquid line 18, and for the case. The inside of the pipe line 30 can be reliably rinsed, and the remaining disinfectant solution can be drained. The routine performed by the control unit 70 from step S41 to step S50 described above is an all-pipe rinsing process in the endoscope cleaning / disinfecting apparatus 1.

  As described above, the disinfecting liquid stored in the cleaning / disinfecting tank 4 is most expected to have the above-mentioned disinfection effect by the heater 53 in the entire line rinsing process as in the water supply line disinfection process. It is heated to the proper temperature. At this time, the control unit 70 supplies a drive signal to the heater 53 based on the detection result from the temperature detection sensor 53a. That is, the heater 53 continues to heat the disinfectant solution to the appropriate temperature.

  Further, based on the detection result from the temperature detection sensor 53a, the control unit 70 stops the driving of the heater 53 when the disinfecting liquid reaches the appropriate temperature. Thereafter, when the temperature of the disinfecting liquid circulating in the apparatus decreases, the control unit 70 drives the heater 53 again based on the detection result of the temperature detection sensor 53a, so that the disinfecting liquid is in the proper state. Warmed to temperature. Thus, based on the detection result of the temperature detection sensor 53a, the disinfecting liquid stored in the cleaning / disinfecting tank 4 and circulating in the apparatus under the control of the driving / stopping of the heater 53 by the control unit 70 has the most disinfecting effect. It is kept at the expected proper temperature.

  As a result of the above, the endoscope cleaning / disinfecting apparatus 1 according to the present embodiment, together with the disinfection of the cleaning / disinfecting tank 4, is selectively performed by the user mainly from the primary side of the water supply filter 17 to the water supply nozzle 24 from the secondary side. The water supply line 9 is disinfected and the circulation line 20, the channel line 21 and the case line 30 are disinfected, and the outer surface of the used endoscope 100 and various channels are washed. Washing and disinfecting liquids are supplied to the circulation line 20 for supplying the liquid, the disinfecting liquid and the rinsing water, the channel line 21 and the flowing liquid line 18, and the washing case 6 for storing various accessories of the endoscope 100. And an all-pipe disinfection program for disinfecting the case pipe 30 for supplying rinsing water.

  The endoscope cleaning / disinfecting apparatus 1 includes a step of rinsing each disinfected line and the cleaning / disinfecting tank 4 with tap water in the water supply line disinfection program and the entire line disinfection program. 23 and the disinfection tube 75 connected to the water supply line disinfection port 7 can be rinsed simultaneously. Therefore, when the user removes the disinfecting tube 75 after the water supply line disinfecting program or the entire line disinfecting program of the endoscope cleaning / disinfecting apparatus 1, no disinfecting liquid remains in the disinfecting tube 75 and the cleaning / disinfecting tank 4. Therefore, there is no need to wear rubber gloves, a mask, etc., and there is no exposure to disinfectant. Furthermore, the user does not need to clean the disinfection tube 75 with another sink or the like.

  Further, based on the detection result of the temperature detection sensor 53a, the disinfecting liquid stored in the cleaning / disinfecting tank 4 and circulating in the apparatus is maintained at an appropriate temperature at which the disinfection effect is most expected by driving / stopping the heater 53. . For this reason, the endoscope cleaning / disinfecting apparatus 1 of the present embodiment can effectively disinfect the pipelines in the apparatus in addition to the disinfection of the endoscope 100.

(Second Embodiment)
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 11 is a schematic configuration diagram illustrating the inside of the endoscope cleaning and disinfecting apparatus, and FIG. 12 is a flowchart illustrating an example of a flow of control performed by the control unit when disinfecting the water supply pipeline of the endoscope cleaning and disinfecting apparatus. FIG. 13 is a flowchart illustrating an example of a flow of control performed by the control unit when disinfecting all the pipelines of the endoscope cleaning / disinfecting apparatus.

  In the present embodiment, the same components as those of the endoscope cleaning / disinfecting apparatus 1 already described in the first embodiment are denoted by the same reference numerals and description thereof is omitted, and only different configurations, operations, and effects are performed. Is mainly explained.

  As shown in FIG. 11, the endoscope cleaning / disinfecting apparatus 1 ′ of the present embodiment is for water supply line disinfection disposed in the cleaning case 6 of the endoscope cleaning / disinfecting apparatus 1 of the first embodiment. The port 7 is not provided, and accordingly, the sterilization conduit 37 in which the check valve 38 is interposed is not provided. Instead, the endoscope cleaning / disinfecting apparatus 1 ′ is connected to each of the pipes 18 and 9 so that the liquid flow pipe 18 communicates with the primary side of the water supply filter 17 of the water supply pipe 9. A connected disinfectant circulation line 76 is provided.

  Specifically, one end of the disinfecting liquid circulation pipe 76 is connected to the flowing liquid pipe 18 by a three-way branch connector 48, and the other end is connected to the water supply pipe 9 between the water supply filter 17 and the check valve 16. Has been. The disinfecting liquid circulation conduit 76 is provided with a disinfecting liquid circulating electromagnetic valve 77 and a check valve 78 in order from the one end connected to the three-way branch connector 48.

  The three-way branch connector 48 is a portion on the primary side of the three-way solenoid valve 10 in the disinfecting liquid circulation conduit 76, that is, the disinfecting liquid circulation solenoid valve 77 side. Are connected with almost no distance between them. Thus, during the normal process, the washing liquid and the disinfecting liquid sent from the liquid pump 19 are supplied to the water supply filter 17 when the three-way solenoid valve 10 is in communication with the water supply line 9 and the water supply nozzle 24. Even if it detours from the primary side, it flows in a state where it is in contact with all of the liquid flow pipes 18.

The operation of the endoscope cleaning / disinfecting apparatus 1 ′ of the present embodiment configured as described above will be described with reference to FIGS. 12 and 13.
First, when the user selects the water supply line disinfection program by the water supply line disinfection button 13d of the sub operation panel 13 and disinfects the water supply line 9, the various pumps and the electromagnetic valves performed by the control unit 70 are set. A flow example of the operation to be controlled will be described according to each step (S) of the flowchart of FIG. Note that, in the following description, portions that overlap with the operations described in the first embodiment will be briefly described.

When the ON signal of the water supply line disinfection button 13d of the sub operation panel 13 is input, the control unit 70 supplies a driving signal to the chemical pump 65 and drives the chemical pump 65 (S61). At this time, the disinfecting liquid stored in the chemical liquid tank 58 flows into the cleaning / disinfecting tank 4 from the disinfecting liquid nozzle 23.
After a while, the disinfecting liquid is stored in the cleaning / disinfecting tank 4, and when the water level reaches a predetermined level, the water level sensor 32 detects the predetermined water level of the disinfecting liquid, and the detection signal is supplied to the control unit 70 (S62). . And the control part 70 supplies a drive signal to the three-way solenoid valve 10, drives the three-way solenoid valve 10 so that the water supply pipe line 9 and the water supply nozzle 24 communicate (S63), and disinfects liquid circulation solenoid valve An open signal is supplied to 77 to open the disinfectant circulation solenoid valve 77 (S64).

  Next, the control unit 70 supplies a drive stop signal to the chemical pump 65 to stop the chemical pump 65, and supplies a start signal to the flow pump 19 to drive the flow pump 19 (S65). At this time, the disinfectant stored in the washing / disinfecting tank 4 is sent from the circulation port 56 to the circulation line 20 by the flow pump 19, passes through the flow line 18, and passes through the three-way branch connector 48. And flows into the disinfectant circulation line 76. Then, the disinfecting liquid flows into the water supply line 9 on the primary side of the water supply filter 17 through the disinfecting liquid circulation electromagnetic valve 77 and the check valve 78 of the disinfecting liquid circulation line 76. The disinfecting liquid that has passed through the water supply filter 17 flows out from the water supply nozzle 24 to the cleaning / disinfecting tank 4 through the three-way solenoid valve 10.

  Thus, the disinfectant liquid disinfects the tank of the cleaning / disinfecting tank 4 at a predetermined water level stored in the cleaning / disinfecting tank 4, and in the water supply line 9, the circulation line 20, the flowing liquid line 18, and It circulates in the disinfectant circulation line 76.

  Next, after a predetermined time has elapsed, the control unit 70 supplies a switching signal to the switching valve 57 and drives the switching valve 57 to the side of the chemical liquid recovery pipeline 61 (S66). Then, after a predetermined time elapses, the control unit 70 supplies a closing signal to the switching valve 57 to close the switching valve (S67), and supplies a driving stop signal to the fluid pump 19 to stop the fluid pump 19. (S68). As a result, the disinfecting liquid stored in the cleaning / disinfecting tank 4 flows from the drain outlet 55 into the chemical recovery pipe 61 and is recovered in the chemical tank 58.

Therefore, the endoscope cleaning / disinfecting apparatus 1 ′ is provided in the cleaning / disinfecting tank 4 at a predetermined water level, in the water supply line 9, in the circulation line 20, in the flowing liquid line 18 and in the disinfecting liquid circulation line 76. Can be sterilized reliably. Incidentally, disinfectant, as described above, the three-way branch connector 48 is liquid flow channel 18, three-way a primary side of the electromagnetic valve 10, the distance between the three-way solenoid valve 10 is almost Since it is connected in a nonexistent state, even if it bypasses from the primary side of the water supply filter 17 through the disinfecting liquid circulation conduit 76, it flows while disinfecting all the flowing liquid conduits 18. The routine performed by the control unit 70 from step S61 to step S68 described above is a water supply line disinfection step in the endoscope cleaning / disinfecting apparatus 1 ′.

  Then, after a sufficient time has passed for the disinfecting liquid to be collected in the chemical tank 58, the control unit 70 supplies an open signal to the water supply electromagnetic valve 15 to open the water supply electromagnetic valve 15 (S69). Thereby, the tap water which is the rinsing water from the water tap 5 flows into the water supply line 9 through the water supply hose 31 a and the water supply hose connection port 31. Then, the tap water is filtered by the water supply filter 17 and flows out into the cleaning / disinfecting tank 4.

  When the tap water stored in the washing / disinfecting tank 4 reaches a predetermined water level, the water level sensor 32 detects it and supplies the detection signal to the control unit 70 (S70). Then, the control unit 70 supplies a start signal to the flow pump 19 to drive the flow pump 19 (S71), supplies a close signal to the water supply electromagnetic valve 15, and closes the water supply electromagnetic valve 15 (S72). In this way, the tap water in the washing / disinfecting tank 4 is sucked from the circulation port 56 by the flow pump 19, flows into the flow line 18 through the circulation line 20, and passes through the flow line 18. It flows into the disinfectant circulation line 76 via the three-way branch connector 48. Then, the tap water flows into the water supply line 9 on the primary side of the water supply filter 17 through the disinfecting liquid circulation electromagnetic valve 77 and the check valve 78 of the disinfecting liquid circulation line 76. The tap water that has passed through the water supply filter 17 flows out from the water supply nozzle 24 to the cleaning / disinfecting tank 4 via the three-way solenoid valve 10.

  Thus, the tap water which is the rinsing water is rinsed in the tank of the cleaning / disinfecting tank 4 at a predetermined water level stored in the cleaning / disinfecting tank 4, and in the water supply line 9, the circulation line 20, and the flowing liquid pipe. It circulates in the path 18 and the disinfectant solution circulation line 76 to rinse the remaining disinfectant solution.

Then, after a predetermined time has elapsed, the control unit 70 supplies a switching signal to the switching valve 57 to drive the switching valve 57 to the drainage pipe 59 side (S73), and supplies a start signal to the drainage pump 60 to supply the drainage pump. 60 is driven (S74). Thus, the tap water stored in the cleaning / disinfecting tank 4 and circulating inside the apparatus is sucked into the drainage pipe 59 from the drain outlet 55 of the cleaning / disinfecting tank 4 through the switching valve 57 by the drain pump 60. , Flows out to the external drain.
After a predetermined time elapses, the control unit 70 supplies drive stop signals to the fluid pump 19 and the drainage pump 60, respectively, stops driving the pumps 26 and 60 (S75), and ends all routines.

  Accordingly, the endoscope cleaning / disinfecting apparatus 1 is disposed in the cleaning / disinfecting tank 4 at a predetermined water level, in the water supply line 9, in the circulation line 20, in the flowing liquid line 18 and in the disinfecting liquid circulation line 76. It can be rinsed securely and the remaining disinfectant can be drained. The routine performed by the control unit 70 from step S69 to step S75 described above is a water supply line rinsing process in the endoscope cleaning / disinfecting apparatus 1 '.

  Note that, similarly to the first embodiment, in the water supply line disinfection process and the entire pipe rinsing process of the present embodiment, the control unit 70 controls the heater 53 based on the detection result of the temperature detection sensor 53a. By the driving / stopping control, the disinfecting liquid stored in the cleaning / disinfecting tank 4 and circulating in the apparatus is maintained at an appropriate temperature at which the disinfection effect can be most expected.

  As a result of the above, the endoscope cleaning / disinfecting apparatus 1 ′ according to the present embodiment is configured such that when the water supply line disinfecting button 13d of the sub operation panel 13 is selected and operated, The inside of the pipe line 9, the inside of the circulation line 20, the inside of the flowing liquid line 18 and the inside of the disinfecting liquid circulation line 76 can be surely disinfected, and the remaining disinfecting liquid can be drained by rinsing water.

  Further, the user who executes the water supply line disinfection program according to the present embodiment uses the disinfection tube 75 as the disinfection liquid nozzle 23, and further the water supply line disinfection port 7 and the air / water supply according to the first embodiment. Even without attaching to the forceps port 33, disinfection and rinsing can be performed in the water supply line 9, the circulation line 20, the flowing liquid line 18, and the disinfecting liquid circulation line 76.

Next, when the user selects the all-pipe disinfection program with the all-pipe disinfection button 13e on the sub operation panel 13 and disinfects each pipe, the control unit 70 controls various pumps and each solenoid valve. An example of the operation flow will be described in accordance with each step (S) of the flowchart of FIG.
First, when the user executes the all-pipe disinfection program, the connector 75a of the disinfection tube 75 is connected to one of the two air / water supply / forceps port 33, and the disinfection tube 75 is washed and disinfected. Install arbitrarily inside.

  In the following description of the flowchart shown in FIG. 13, in each routine performed by the control unit 70, Step 81 to Step 85, Step 89, Step 92 to Step 95, and Step 99 in FIG. Since the operations are the same as Step 65, Step 67, Step 69 to Step 72, and Step 74, their descriptions are omitted or simplified.

  When the user selects and operates the all-pipe disinfection button 13e on the sub operation panel 13, the control unit 70 performs each of steps S81 to 85 in FIG. 12 in the same manner as steps S61 to S65 in FIG. Control operation of the pump and each solenoid valve.

  The disinfecting liquid disinfects the tank of the cleaning / disinfecting tank 4 at the predetermined water level stored in the cleaning / disinfecting tank 4 by driving the chemical pump 65 in step 85, and in the water supply line 9 and the circulation line 20. The sterilization is performed while circulating in the liquid flow line 18 and the disinfectant circulation line 76.

  After a predetermined time has elapsed, the control unit 70 supplies a switching signal to the three-way solenoid valve 10 to drive the three-way solenoid valve 10 toward the fluid flow line 18 (S86), and sends a drive stop signal to the fluid pump 19. Then, the flow pump 19 is stopped and a start signal is supplied to the channel pump 26 to drive the channel pump 26 (S87). As a result, the disinfecting liquid stored in the cleaning / disinfecting tank 4 is sent from the circulation port 56 through the circulation line 20 into the channel line 21 by the suction of the channel pump 26, and the channel of the channel line 21. After passing through the block 27, the gas flows into the case conduit 30 and the channel conduit 21 on the air / water supply / forceps port 33 side.

  Then, the disinfecting liquid that has flowed into the case conduit 30 flows out of the cleaning case 6 into the cleaning / disinfecting tank 4 through the relief valve 36. On the other hand, the disinfectant flowing into the channel pipe 21 on the air / water supply / forceps port 33 side passes through the CH electromagnetic valve 28 and the check valve 29 and passes through the air / water supply / forceps port 33. Then, the gas flows into the disinfection tube 75 and flows out again from the air / water supply / forceps port 33 to the cleaning / disinfecting tank 4.

  Thus, the disinfectant liquid disinfects the tank of the cleaning / disinfecting tank 4 at a predetermined water level stored in the cleaning / disinfecting tank 4, and in the circulation conduit 20, the channel conduit 21, the case conduit 30, and Disinfection is performed while circulating in the disinfection tube 75.

  Next, the control unit 70 opens the CH electromagnetic valve 28, supplies a switching signal to the switching valve 57 after a predetermined time has elapsed, and drives the switching valve 57 to the side of the chemical liquid recovery pipeline 61 (S88). Then, after a predetermined time has passed, the control unit 70 supplies a close signal to the switch valve 57 to close the switch valve 57 (S89), and supplies a drive stop signal to the channel pump 26 to stop the channel pump 26 ( S90). As a result, the disinfecting liquid stored in the cleaning / disinfecting tank 4 flows from the drain outlet 55 into the chemical recovery pipe 61 and is recovered in the chemical tank 58.

  Accordingly, the endoscope cleaning / disinfecting apparatus 1 is provided in the cleaning / disinfecting tank 4 at a predetermined water level, in the water supply line 9, in the circulation line 20, in the channel line 21, in the flowing liquid line 18, and for the case. The inside of the pipe line 30 and the inside of the disinfectant circulation pipe line 76 can be surely disinfected. The routine performed by the control unit 70 from step S81 to step S90 described above is an all-pipe disinfection step in the endoscope cleaning / disinfecting apparatus 1 ′.

  After a sufficient time has passed for the disinfectant to be collected in the chemical tank 58, the control unit 70 supplies a switching signal to the three-way solenoid valve 10 to drive the three-way solenoid valve 10 toward the water supply line 9 (S91). ), An open signal is supplied to the water supply electromagnetic valve 15 to open the water supply electromagnetic valve 15 (S92). Thereby, the tap water which is the rinsing water from the water tap 5 flows out from the water supply nozzle 24 into the washing / disinfecting tank 4.

  When the tap water stored in the washing / disinfecting tank 4 reaches a predetermined water level, the water level sensor 32 detects it, and the detection signal is supplied to the control unit 70 (S93). Then, the control unit 70 supplies a start signal to the flow pump 19 to drive the flow pump 19 (S94), supplies a close signal to the water supply electromagnetic valve 15, and closes the water supply electromagnetic valve 15 (S95). . Thus, the tap water which is the rinsing water in the cleaning / disinfecting tank 4 is rinsed in the tank of the cleaning / disinfecting tank 4 at a predetermined water level stored in the cleaning / disinfecting tank 4, and in the water supply line 9 and the circulation line. 20 is circulated in the flow line 18 and the disinfectant circulation line 76 to rinse the remaining disinfectant liquid.

  After a predetermined time elapses, the control unit 70 supplies a switching signal to the three-way solenoid valve 10 to switch the three-way solenoid valve 10 to the fluid flow line 18 side (S96) and stop driving the fluid pump 19. The flow pump 19 is stopped by supplying a signal, and a start signal is supplied to the channel pump 26 to drive the channel pump 26 (S97). Thus, the tap water as the rinsing water is further rinsed in the tank of the cleaning / disinfecting tank 4 and the circulation line 20 at a predetermined water level stored in the cleaning / disinfecting tank 4, and mainly in the channel line 21 and It circulates in the case conduit 30 and rinses the remaining disinfectant solution.

After a predetermined time has elapsed, the control unit 70 supplies a switching signal to the switching valve 57, drives the switching valve 57 to the drain line 59 (S98), supplies a start signal to the drain pump 60, and the drain pump 60. Is driven (S99). Thus, the tap water stored in the washing / disinfecting tank 4 and circulating inside the apparatus is sucked into the drainage pipe 59 from the draining port 55 of the washing / disinfecting tank 4 through the switching valve 57 by the drainage pump 60. , Flows out to the external drain.
After a predetermined time has elapsed, the control unit 70 supplies drive stop signals to the fluid pump 19 and the drainage pump 60, stops the pumps 19 and 60 (S100), and ends all routines.

  Therefore, the endoscope cleaning / disinfecting apparatus 1 'is provided in the cleaning / disinfecting tank 4 at a predetermined water level, in the water supply line 9, in the circulation line 20, in the channel line 21, in the flowing liquid line 18, in the disinfection line. The inside of the liquid circulation line 76 and the case line 30 can be reliably rinsed, and the remaining rinsing water can be drained. The routine performed by the control unit 70 from step S91 to step S100 described above is the all-pipe rinsing process in the endoscope cleaning / disinfecting apparatus 1 ′.

  As a result, the endoscope cleaning / disinfecting apparatus 1 'according to the present embodiment can obtain the same effect as the endoscope cleaning / disinfecting apparatus 1 according to the first embodiment, and is disinfected at the time of executing the water supply line disinfecting program. There is an advantage not involving the work of attaching the tube 75. Further, even when the user executes the all-pipe disinfection program, the user only needs to connect the disinfection tube 75 to the air / water supply / forceps port 33.

  In the first and second embodiments described above, the entire pipeline of the endoscope cleaning / disinfecting apparatus 1 (1 ′) is a cleaning liquid when cleaning / disinfecting the used endoscope 100. In the endoscope cleaning / disinfecting apparatus 1 according to the first embodiment, specifically, the water supply line 9, the flowing liquid line 18, and the circulation line 20. , A channel line 21, a case line 30, and a disinfection line 37. In the endoscope cleaning and disinfecting apparatus 1 'according to the second embodiment, the water supply line 9, the flowing liquid line 18, and the circulation line The channel 20, the channel channel 21, the case channel 30, and the disinfectant circulation channel 76.

  In both the embodiments, the air pipe 44 is a check valve 47, the alcohol pipe is an electromagnetic valve 43, and the cleaning agent pipe 39 is an independent pipe. The disinfectant does not enter. Furthermore, the chemical liquid pipe 64 is a pipe through which only the disinfecting liquid passes.

(Third embodiment)
Next, a third embodiment of the present invention will be described with reference to the drawings. FIG. 14 is a schematic configuration diagram showing the inside of the endoscope cleaning / disinfecting apparatus.
In the present embodiment, the same components as those of the endoscope cleaning / disinfecting apparatus 1, 1 ′ already described in the first and second embodiments are denoted by the same reference numerals, and the description thereof is omitted. Only the different configurations, functions, and effects will be mainly described. In the description of the present embodiment, the second embodiment will be described as a modified example in which a new pipe line configuration is provided on the basis of the endoscope cleaning / disinfecting apparatus 1 of the first embodiment. It may be applied to the endoscope cleaning / disinfecting apparatus 1 ′.

Now, an internal conduit configuration of the endoscope cleaning / disinfecting apparatus 1 ″ according to the present embodiment will be described with reference to FIG.
As shown in FIG. 14, a three-way branching member 81 is interposed between the chemical liquid pump 65 and the suction filter 63 in the chemical liquid pipe 64. One end of the dilution pipe 83 is connected to the three-way branch member 81, and the other end of the dilution pipe 83 is connected to the secondary side of the water supply filter 17 in the water supply pipe 9. Further, an electromagnetic valve 82 is interposed in the middle of the dilution pipe 83.

  Usually, the disinfecting liquid injected into the chemical liquid tank 58 from the chemical liquid bottle 12a is a concentrated disinfecting liquid for dilution or a practical disinfecting liquid set to a predetermined concentration. In the case of using the dilution concentrated disinfectant, conventionally, the tap water from the water tap 5 is filtered by the water supply filter 17 through the water supply line 9 in order to dilute the dilution concentrated disinfectant to a predetermined concentration. Then, the water is fed from the water supply nozzle 24 to the cleaning / disinfecting tank 4, and is injected from the drain outlet 55 through the chemical recovery pipe 61 into the chemical tank 58 by a predetermined amount. In addition, the chemical tank 58 is provided with a water level detection sensor (not shown), and an injection amount of tap water at which the dilution disinfectant has a predetermined concentration is set.

  Further, when the disinfectant solution is replaced, the suction filter 63 provided at one end of the chemical solution pipe 64 may be clogged with foreign matter or the like attached to the chemical solution tank 58 or the used endoscope. is there. When the user is clogged with the suction filter 63, the user has to remove the chemical tank 58 and disassemble various pipes in order to remove the clogging and clean up. There is no problem. Further, when the suction filter 63 is clogged, not only the speed at which the disinfecting liquid is pumped into the cleaning / disinfecting tank 4 is reduced, but also a burden is caused on the chemical liquid pump 65, which causes a failure.

  In the conventional endoscope cleaning / disinfecting apparatus, as another diluting method for diluting the concentrated disinfecting liquid for dilution, a three-way branch member is provided in the chemical liquid recovery pipe 61, and a dilution pipe 83 is provided in the three-way branch member. There is a type in which tap water filtered by the water supply filter 17 is injected into the chemical tank 58. In this configuration, tap water can be supplied from the dilution pipe 83 to the chemical tank 58 through the chemical recovery pipe 61, but the chemical pipe 64 cannot be rinsed.

  Furthermore, since the conventional endoscope cleaning / disinfecting apparatus basically has a configuration in which only the disinfecting liquid flows through the chemical liquid conduit 64, the chemical liquid conduit 64 including the disinfecting liquid nozzle 23, the chemical liquid pump 65, and the suction filter 63. Could not be rinsed. In addition, the chemical liquid pipe 64 and the chemical liquid pump 65 through which only the disinfecting liquid flows are preferably rinsed with tap water in view of the durability of the parts.

  Furthermore, in the case of an endoscope cleaning / disinfecting apparatus that has not been used for a long period of time, if there is dust, foreign matter, etc. in the cleaning / disinfecting tank 4, it will enter the chemical solution tank 58 together with tap water, It may cause clogging.

  Therefore, in the endoscope cleaning / disinfecting apparatus 1 ″ according to the present embodiment, as described above, the pipe configuration is such that tap water, which is rinsing water, can flow directly to the chemical pump 65. That is, when replacing the disinfecting liquid that has reached the predetermined number of times stored in the chemical liquid tank 58, or for the endoscope cleaning / disinfecting apparatus 1 ″ that has not been used for a long time, a new one is added. When exchanging with the disinfectant, etc., tap water, which is a rinse water, can be once poured back into the chemical tank 58 through the suction filter 63.

  More specifically, the control unit 70 closes the three-way electromagnetic valve 10 of the flowing liquid pipe 18 in a direction in which the water supply pipe 9 and the water supply nozzle 24 do not communicate with each other, opens the electromagnetic valve 82 of the dilution pipe 83, and supplies water. Open the solenoid valve 15.

  As a result, tap water from the tap 5 passes through the water supply filter 17 in the water supply line 9, flows to the dilution line 83, and flows from the suction filter 63 into the chemical liquid tank 58 via the chemical liquid line 64. As a result, foreign matter clogged due to adhesion or the like is washed off the suction filter 63 by the water pressure of tap water which is rinsing water. Then, the tap water is discharged into the chemical solution tank 58 together with foreign substances and the like, and the inside of the chemical solution tank 58 is rinsed.

  At the same time as the tap water flowing into the chemical liquid pipe 64 is discharged into the chemical liquid tank 58. It also flows to the chemical liquid pump 65 side, rinses the inside, and is discharged from the disinfecting liquid nozzle 23 to the cleaning / disinfecting tank 4.

  At this time, the control unit 70 opens the switching valve 57 provided in the cleaning / disinfecting tank 4 to the drainage pipe 59 side, and the tap water mixed with foreign matters in the cleaning / disinfecting tank 4 is supplied via the drainage pump 60. Drain from the external drain.

  Further, when tap water is stored in the chemical liquid tank 58, the control unit 70 closes the water supply electromagnetic valve 15 and drives the chemical liquid pump 65 by detection of a water level detection sensor (not shown).

  Thus, the tap water stored in the chemical liquid tank 58 is sucked up from the suction filter 63 to the chemical liquid pipe 64 and flows from the disinfecting liquid nozzle 23 into the cleaning / disinfecting tank 4.

  Thereafter, the control unit 70 drives the drain pump 60 with the switching valve 57 switched to the drain line 59 side. Thus, the tap water rinsed in the chemical tank 58 is drained to the external discharge port via the cleaning / disinfecting tank 4.

  By performing the above-described operation several times, the inside of the chemical liquid tank 58 is washed, and the foreign matters that adhere to the suction filter 63 and are clogged are washed.

  When the tap water in the cleaning / disinfecting tank 4 is drained, the control unit 70 stops the drain pump 60, closes the electromagnetic valve 82 of the dilution pipe 83, and closes the three-way solenoid valve 10 of the flowing liquid pipe 18. Is opened in a direction in which the water supply line 9 and the water supply nozzle 24 communicate with each other, the water supply electromagnetic valve 15 is opened, and tap water is supplied from the water supply nozzle 24 into the washing / disinfecting tank 4. At this time, the switching valve 57 is switched to the chemical solution recovery pipeline 61 side, and the chemical solution pump 65 is driven.

  Thereby, the tap water in the washing / disinfecting tank 4 flows from the drain outlet 55 into the chemical tank 58 via the switching valve 57 and the chemical recovery pipe 61. Then, it is sucked up from the suction filter 63 to the chemical liquid pipe 64 by the chemical liquid pump 65 and flows again into the cleaning / disinfecting tank 4 from the disinfecting liquid nozzle 23. In this way, the tap water is rinsed while circulating in the chemical solution recovery pipeline 61, the chemical solution tank 58, and the chemical solution pipeline 64.

  The tap water is circulated in a predetermined time, and then the control unit 70 switches the switching valve 57 to the drain line 59 side and drives the drain pump 60. Thus, the tap water is drained to the external drain. Since the chemical pump 65 continues to be driven, all the tap water in the chemical tank 58 flows from the disinfecting liquid nozzle 23 to the cleaning / disinfecting tank 4 and is drained to the outside. And after predetermined time progress, the control part 70 stops the drainage pump 60 and the chemical | medical solution pump 65. FIG.

  As a result of the above, the endoscope cleaning / disinfecting apparatus 1 ″ according to the present embodiment rinses the inside of the chemical liquid tank 58, cleans the clogged foreign matter attached to the suction filter 63, and discharges it to the outside. It is the structure which can do. In addition, the tap water is usually circulated in the chemical liquid conduit that is not rinsed. As a discharge path from the chemical tank 58, a drain hose (not shown) may be connected to the chemical drain pipe line 58a.

  Further, when a new antiseptic solution for dilution is poured into the chemical tank 58 from the chemical bottle 12 a and diluted with tap water filtered by the water supply filter 17, it is poured into the chemical tank 58 via the dilution pipe 83. . At this time, the control unit 70 closes the three-way electromagnetic valve 10 of the liquid flow line 18 in a direction in which the water supply line 9 and the water supply nozzle 24 do not communicate with each other, opens the water supply electromagnetic valve 15, and opens the water supply electromagnetic valve 15. Open 82.

  Thus, tap water from the tap 5 is filtered through the water supply filter 17 and flows from the suction filter 63 into the chemical liquid tank 58 through the water supply pipe 9 through the dilution pipe 83 and the chemical liquid pipe 64. When the water level of the disinfecting liquid diluted by a water level sensor (not shown) in the chemical liquid tank 58 is detected, the control unit 70 supplied with the detection signal from the water level sensor closes the water supply valve. Accordingly, the endoscope cleaning / disinfecting apparatus 1 ″ according to the present embodiment is configured such that the disinfecting liquid for dilution is diluted to a predetermined concentration with the tap water in the chemical liquid tank 58.

  The user is provided in the sub operation panel 13 shown in FIG. 4 in order to dilute the concentrated disinfectant for dilution to a predetermined concentration while washing the above-described suction filter 63 and rinsing the chemical liquid pipe 64. The disinfection liquid preparation button 13g is turned on.

(Fourth embodiment)
Next, a fourth embodiment of the present invention will be described with reference to the drawings. 15 is an external view of an alcohol tank, FIG. 16 is an external view of a hollow cap provided in a ventilation tube, FIG. 17 is a sectional view of a hollow cap provided in the ventilation tube, and FIG. 18 is a hollow cap provided in the ventilation tube. FIG. 19 is an operation explanatory view of the hollow cap connected to the connection cap.
In the present embodiment, the same components as those of the endoscope cleaning / disinfecting apparatus 1, 1 ′, 1 ″ already described in the first to third embodiments are denoted by the same reference numerals. Are mainly described only for different configurations, functions, and effects.

  In the first to third embodiments described above, when the used endoscope 100 is cleaned and disinfected in the endoscope cleaning and disinfecting apparatus 1, 1 ′, 1 ″, finally the endoscope channel In order to accelerate the drying of the inside, an alcohol flushing process for supplying highly volatile alcohol into the endoscope duct is performed. The alcohol used in the alcohol flushing process is filled in the alcohol tank (11b).

  Conventionally, an alcohol tank is filled with alcohol every time a used endoscope is cleaned or disinfected. Since this alcohol tank is not provided with a sealed lid or the like, the alcohol in the alcohol tank is transferred to another container at the end of the day's work. This is always performed by the user in order to prevent the highly volatile alcohol from evaporating.

  Therefore, the user must perform the troublesome work of removing the alcohol tank from the apparatus and transferring the alcohol to another container on a daily basis.

Therefore, the alcohol tank 11b according to the present embodiment has a configuration that does not require an operation of transferring the alcohol inside to another container, as shown in FIGS.
More specifically, the alcohol tank 11b according to the present embodiment includes a container main body 84 in which alcohol is stored, and a detachable connection cap 85 provided at the approximate center of the upper surface of the container main body 84 as viewed in the plane of FIG. And a ventilation tube 86 having one end connected to the upper surface.

  On one side surface of the container main body 84, a groove portion 84a formed from the upper side to the lower side is formed. As can be seen from FIG. 15, in this embodiment, the groove 84 a is formed in a vertically divided shape so as to divide into two parts from one surface of the substantially cylindrical shape toward the other surface.

  The cap 85 communicates with the hole 85a serving as a first opening of the alcohol tank 11b provided on the upper surface when viewed toward the paper surface of FIG. It has a tube 85b extending to the vicinity of the bottom surface. When the alcohol tank 11b is set in the detergent / alcohol tray 11 (see FIG. 2), the alcohol in the container body 84 can be sucked into the hole 85a by the alcohol supply pump 42 via the tube 85b. In order to do this, one end of the alcohol pipe 41 is connected in a predetermined manner.

  The other end of the ventilation tube 86 is provided with a hollow cap 87 which is an airtight means made of synthetic resin and is a sealing member. Normally, the alcohol tank 11 b is accommodated in the detergent / alcohol tray 11 with the ventilation tube 86 along the groove 84 a of the container body 84.

  As shown in FIGS. 16 and 17, the hollow cap 87 provided in the ventilation tube 86 is a tubular member in which a through hole is formed on a substantially central axis, and one opening of this through hole has an alcohol tank 11b. It becomes the front-end | tip opening part 87a used as the 2nd opening part. Further, the hollow cap 87 is formed on the side of the distal end portion, in this case, toward the base end so that the two notches 87b face the body, and has an outward flange portion 87c at the approximate center in the axial direction. ing.

  The hollow cap 87 has a locking portion 87d whose outer end portion has a shape like a so-called rugby ball, and whose outer end portion has a substantially conical shape as shown in FIG. Have. The distal end portion of the hollow cap 87 has a maximum outer diameter orthogonal to the axial direction slightly larger than the hole diameter of the hole portion 85a of the connection cap 85, and the locking portion 87d on the proximal end side is ventilated. The tube 86 is inserted through the opening at the other end, and is locked by the locking portion 87d so as not to fall out of the ventilation tube 86.

  A rubber packing 88 is inserted from the front end side of the hollow cap 87, and one surface of the rubber packing 88 is in contact with the outward flange portion 87 c of the hollow cap 87. As shown in FIGS. 18 and 19, the rubber packing 88 is formed on the upper surface of the connection cap 85 opposite to the outward flange portion 87 c when the distal end portion of the hollow cap 87 is inserted into the hole 85 a of the connection cap 85. The surfaces are in contact with each other so that the connection cap 85 and the hollow cap 87 are hermetically sealed.

  Specifically, as shown in FIG. 19, the hollow cap 87 is inserted into the hole 85 a of the connection cap 85 from the tip portion by one touch by the user. At this time, the outer shape in the direction orthogonal to the axial direction of the distal end portion of the hollow cap 87 is deformed to be small by the notch portion 87 b and can pass through the hole portion 85 a of the connection cap 85. Thereafter, the hollow cap 87 is connected to the connection cap 85 in a state where the outer shape of the tip portion returns to the original state and one surface of the rubber packing 88 is in contact with the upper surface of the connection cap 85.

  As a result, according to the alcohol tank 11b of the present embodiment, the inside of the alcohol tank 11b is hermetically sealed by the one-touch connection between the connection cap 85 and the hollow cap 87, and the alcohol inside flows out to the outside due to vaporization or the like. Can be prevented. Therefore, the user does not need to perform the troublesome work of transferring the alcohol in the alcohol tank 11b to another container at the end of the day's work.

  The alcohol tank 11b can be stored in the detergent / alcohol tray 11 in a state where the hollow cap 87 is connected to the connection cap 85 and the internal alcohol is hermetically sealed. As a result, there is no need to provide a storage space for the alcohol tank 11b outside the apparatus, and there is no need for a separate container for transferring alcohol.

  Further, as shown in FIGS. 20 to 22, the hole 85 a of the connection cap 85 that is the first opening and the opening at the other end of the ventilation tube 86 that is the second opening here. The alcohol tank 11b may be sealed so that the inside of the alcohol tank 11b is hermetically sealed.

FIG. 22 is an external view of an alcohol tank for explaining a sealing member that hermetically seals the hole of the connection cap and the opening of the ventilation tube.
As shown in FIG. 20, the sealing member that is an airtight means hermetically seals the hole 85a (not shown in FIG. 20) of the connection cap 85, and has a protrusion 89a that protrudes conically from one surface. The alcohol tank 11b may be hermetically sealed with the sealing cap 89.

  The sealing cap 89 is attached to the upper end of the connection cap 85, and the inside of the alcohol tank 11b can be hermetically sealed by inserting the opening of the ventilation tube 86 into the protrusion 89a. Further, the connection cap 85 and the sealing cap 89 are connected by a chain 90, so that the sealing cap 89 is prevented from being lost. The sealing cap 89 may be hollow or solid, and the inside of the alcohol tank 11b can be hermetically sealed.

  Further, as shown in FIG. 21, the sealing member that is an airtight means hermetically seals the first plug 91 that hermetically seals the hole 85 a of the connection cap 85 and the opening of the ventilation tube 86. The alcohol tank 11b may be hermetically sealed by the first and second plug bodies 91 and 92.

  Further, as shown in FIG. 22, the sealing member that is an airtight means is one plug member that seals the hole 85a of the connection cap 85 and the opening of the ventilation tube 86 in an airtight manner. A U-shaped plate 93 may be used. The plate 93 includes a first plug 94 on the lower surface on the upper side and a second plug 95 on the upper surface on the lower side, as viewed toward the paper surface of FIG. The hole 94 a of the connection cap 85 is hermetically sealed by the body 94, and the opening of the ventilation tube 86 is hermetically sealed by the second plug 95.

  With the above-described configuration in which the inside of the alcohol tank 11b shown in FIGS. 20 to 22 is hermetically sealed, the alcohol tank 11b can be stored in the detergent / alcohol tray 11 in an airtight state. This eliminates the need to provide a storage space for the alcohol tank 11b outside the apparatus, and eliminates the need for a separate container for transferring alcohol.

  The present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.
