  A conventional endoscope cleaning / disinfecting apparatus will be described. As shown in FIG. 6, as the first case, in the configuration in which the first liquid supply source container 101 a and the second liquid supply source container 101 b are arranged on the upper part of the liquid supply destination container 102, the first liquid When the liquid is supplied to the liquid supply destination container 102 from the supply source container 101a and the second liquid supply source container 101b using the pumps 200 and 201, the liquid is usually passed through the pumps 200 and 201 by the flow indicated by the broken line. Although it is supplied to the liquid supply destination container 102, even if the pumps 200 and 201 are stopped, the first liquid supply source container 101a and the second liquid supply source container 101b are shown by the two-dot broken line due to the siphon phenomenon. From the liquid to the liquid supply destination container 102 continues.

  Further, as shown in FIG. 7, as the second case, in the configuration in which the first liquid supply source container 101 a and the second liquid supply source container 101 b are disposed below the liquid supply destination container 102, When the liquid is supplied from the liquid supply source container 101a and the second liquid supply source container 101b to the liquid supply destination container 102 using the pumps 200 and 201, the flow is normally indicated by the flow indicated by the broken line via the pumps 200 and 201. Although the liquid is supplied to the liquid supply destination container 102, when the pumps 200 and 201 are stopped, the first liquid supply source container 101a and the first liquid supply source container 101a are connected to the first supply source container 101a from the liquid supply destination container 102 as indicated by a two-dot broken line due to siphon phenomenon.

  Therefore, as shown in FIGS. 8 and 9, for the first and second cases, a tube from the first liquid supply source container 101a and the second liquid supply source container 101b to the liquid supply destination container 102 is used. By providing check valves 220 and 221 on the road, as shown in FIG. 10, the liquid outflow time is changed from the first timing lag time to the second timing lag time by the cracking pressure of the check valves 220 and 221. Thus, the continuation of the outflow of liquid and the occurrence of siphon phenomenon can be suppressed.

  As shown in FIG. 11, as a third case, the liquid from the first liquid supply source container 101a and the second liquid supply source container 101b is liquidized by pressurization using a compressor 180 and a pressurization tank 181. Conventionally, when supplying to the supply destination container 102, the three-way valves 252 and 253 are provided in the respective pipelines. However, as described above, the first liquid supply source container 101a and the second liquid supply source container are provided. Due to the arrangement of 101b with respect to the liquid supply destination container 102, the continuation of the outflow of liquid and the siphon phenomenon occur.

  Therefore, in the case of such a third case, as shown in FIG. 12, from the first liquid supply source container 101a and the second liquid supply source container 101b in the next stage of the three-way valves 182 and 183, By providing the three-way valves 252 and 253 in the pipelines to the liquid supply destination container 102, as shown in FIG. 13, the liquid outflow time is set to the first timing due to the cracking pressure of the three-way valves 252 and 253. The lag time can be shortened to the second timing lag time, and the continuation of the liquid outflow and the occurrence of the siphon phenomenon can be suppressed.
