この発明は洗浄液を貯える貯液タンクを備えた内視鏡用
洗浄装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an endoscope cleaning device equipped with a liquid storage tank for storing cleaning liquid.
内視鏡は、使用することによってその外表面だけでなく
吸引用、送気送水用あるいは鉗子チャンネルなどの管路

するようにしている。On the other hand, a plurality of water level detectors are installed in the liquid storage tank in order to always store a certain amount of water here. A first water level detector that detects the upper limit of the water level and a second water level detector that detects the lower limit are provided, and these detection signals open and close the solenoid valve to keep the water level in the liquid storage tank constant. A third water level detector is provided below the water level detector, so that it can be detected that the water level in the liquid storage tank has constantly decreased.

水位を一定に保つことができないという問題があった。By the way, conventionally, a liquid storage tank and a faucet which is a supply source of tap water are connected by piping via the above-mentioned electromagnetic valve, and tap water is directly flowed into the liquid storage tank from this piping. Therefore,
The liquid flows into the storage tank, causing the water level detector to malfunction.
There was a problem that the water level could not be kept constant.

路内に導入する導入部に接続されている。2) One end of the water supply pipe 7 is connected to the peripheral wall of the inlet 30. 1. ing. This water supply pipe 7 is provided with a solenoid valve 8 in the middle,
The other end is connected to a tap water faucet (not shown) that is a supply source of cleaning fluid. Furthermore, first to third water level detectors 9, 10, and 11 are sequentially provided on the inner surface of the other end of the liquid storage portion 2 from above. That is, the first water level detector 9 detects the upper limit of the water level in the liquid storage tank 1, and in response to this detection signal, closes the electromagnetic valve 8 to stop the flow of tap water into the liquid storage tank 1. The second water level detector 10 detects the lower limit of the water level in the liquid storage tank 1, and based on this detection signal, the electromagnetic valve 8
is opened to allow tap water to flow into the liquid storage tank 1. That is, the water level in the liquid storage tank 1 is maintained between the first water level detector 9 and the second water level detector 10. Further, the third water level detector II detects an abnormally low water level in the liquid storage tank 1, and issues, for example, an alarm based on this detection signal. Furthermore, a drain pipe 12 is provided at the bottom of the liquid storage section 2 with one end connected thereto. This drain pipe 12 has a liquid supply (not shown) in the middle part, I? The other end is guided to a cleaning tank (not shown) in which an endoscope is installed, and here there is a cleaning nozzle that sprays tap water onto the surface of the endoscope and an introduction section that introduces it into the endoscope's conduit. It is connected to the.

がない。In the cleaning device configured as described above, the liquid feeding pump provided in the drain pipe 12 is operated to supply tap water to the drain pipe 12.
When the endoscope installed in the cleaning tank is washed, the water level of the tap water in the liquid storage tank 1 becomes lower than that of the second water level detector 10. Then, the electromagnetic valve 8 is opened by the detection signal from the second water level detector 10, and tap water is supplied to the liquid storage tank I. That is, tap water flows into the inflow part 3 of the liquid storage tank 1 at a predetermined pressure,
The force is weakened to some extent by the inner surface of the peripheral wall of the inflow portion 3 and then falls onto the plate-like body 6. After the tap water's force is further weakened by falling onto the plate-like body 6, it flows into the liquid storage part 2 through the gap between the periphery of the plate-like body 60 and the inner peripheral surface of the inlet part 3. . That is, since the tap water flows into the liquid storage part 2 after its force has been sufficiently weakened, there is no possibility that a vortex is generated in the liquid storage part 2 and the water surface is greatly undulated.

ことになる。Therefore, when the water level in the liquid storage section 2 rises, the first water level detector 9 reliably detects the actual water level, and this detection signal closes the solenoid valve 8 to stop the supply of tap water. do. In this way, the water level of the liquid storage section 2 is maintained between the first water level detector 9 and the second water level detector 10 (C).

It may also have a configuration as shown in the figure. First, the third
In the embodiment shown in the figure, a net-like partition plate 15 made of a wire mesh or the like is provided in the liquid storage part 2 in addition to the plate-like member 6 as a damping means, and the inside of the liquid storage part 2 is It was divided into a part where the water level detectors 9, 1θ, . . . According to such a configuration, even if a certain degree of vortex is generated by the tap water flowing into the liquid storage section 2 from the inflow section 3, this vortex is canceled by the mesh partition plate 15, so that the first to third The water surface in the area where the water level detector 9°10.11 is installed is often undulating.

貯液部２に流がすことができる。In addition, FIG. 4 shows a plate-like body 6 in which a large number of outflow holes 16 are bored, and FIG. 5 shows a plate-like body 6 made by stacking a plurality of mesh-like plates 17 such as wire mesh. According to these plate-like bodies 6, when the amount of tap water flowing into the inflow section 3 increases, the tap water can be allowed to flow into the liquid storage section 2 so that it does not accumulate too much in the inflow section 3. I can do it.

一定に保つことができる。As described above, this invention provides a liquid storage tank equipped with a water level detector for detecting the water level of the cleaning liquid inside, and a damping means for attenuating the force of the cleaning liquid flowing into the tank. As a result, eddy currents are generated in the liquid storage tank, and the water surface does not ripple greatly. Therefore, since the water level detector operates reliably depending on the actual water level and does not malfunction, the water level in the liquid storage tank can be kept constant.
