Although not shown, the operation unit 21 is provided with a forceps insertion port, a suction button, an air / water supply button, and the like. The endoscope 20 is widely used in this kind of field, and has various known designs in addition to the illustrated embodiment as long as it has basic functions and configurations. You may have.

  Referring to FIG. 4, the washing tub 30 is located on the front surface 2 side of the apparatus main body 10 and has an opening 31 a extending in the vertical direction Y on the front surface 2 and an arrangement surface (bottom wall) for arranging the endoscope 20. 31, a lower wall portion 32, and first and second side wall portions 33 and 34 that extend in the vertical direction so as to face each other in the width direction. In addition, for convenience of explanation, the washing tank 30 (or the arrangement surface 31) includes an upper area 30A located on the upper surface 4 side of the apparatus main body 10, a lower area 30B located on the lower surface 5 side of the apparatus main body 10, and a space therebetween. It is divided into the intermediate area 30C located in the area. A filter cover 19 that covers a cylindrical water purification filter housed inside is disposed in the intermediate area 30C and the lower area 30B of the arrangement surface 31.

  A plurality of spray nozzles that spray cleaning water for cleaning the endoscope 20 locked to the fixed rack 50 on the inner surfaces and the arrangement surfaces 31 of the first and second side wall portions 33 and 34 of the cleaning tank 30. 35a-35h are arranged. The washing water sprayed from the spray nozzles 35a to 35h includes, in addition to general tap water, strong alkaline electrolyzed water, strong acid electrolyzed water obtained by electrolyzing saline, tap water and a mixture of various chemicals. A liquid or the like can be used. Moreover, tap water, strong alkaline electrolyzed water, and strongly acidic electrolyzed water can also be used in an appropriate order. The washing water after washing is collected in a water storage tank (not shown) from the drain port 16 located in the lower wall portion 32 of the washing tank 30 and then discharged outside the washing tank 30. An intake port 18 for discharging chlorine gas generated in the washing tank to the outside is located on the inner surface of the first side wall 33.

  The injection nozzles 35a to 35h are disposed in the upper area 30A, the intermediate area 30C, and the lower area 30B of the washing tub 30, respectively. Each of the injection nozzles 35 a to 35 h has a predetermined injection zone, and can wash the washing water uniformly over the entire endoscope 20 suspended from the fixed rack 50. Specifically, washing water is supplied to each of the operation section 21, the insertion section 23, and the connector section 22 of the endoscope 20 by the ejection nozzles 35a to 35c located in the upper area 30A and the ejection nozzles 35d and 35e located in the intermediate area 30C. Can be injected. Moreover, the washing water can be sprayed to the first and second cord portions 24 and 25 by the spray nozzles 35f and 35h located in the lower area 30B. The injection nozzle 35g is located in a side space 138, which will be described later, and injects washing water into the first and second cord portions 24, 25 in the side space 138 from above.

  The injection nozzles 35a to 35h are positioned so as to face each other in the width direction X, and are arranged so that a part of their injection regions overlap each other. Therefore, for example, the first group consisting of the injection nozzles 35a, 35c, 35e, and 35g and the second group consisting of the injection nozzles 35b, 35d, 35f, and 35h are alternately injected so that there is no blind spot in the entire endoscope 20. Can be injected.

  If FIG. 3 is referred, the arrangement | positioning surface 31 of the washing tank 30 will incline with respect to the installation surface (floor surface) 11 in which the washing apparatus 10 was installed. Specifically, the intersection angle α between the installation surface 17 and the virtual extension line K1 of the arrangement surface 31 is 40 to 85 degrees, preferably 70 to 80 degrees. When the crossing angle α is 40 degrees or less, the operator (operator, for example, a nurse) must bend greatly in order to fix the endoscope 20 to the fixed rack 50. A big burden. On the other hand, when the intersection angle α exceeds 85 degrees, the placement surface 31 stands up almost vertically in front of the operator, and thus it may be difficult to place the endoscope 20 on the placement surface 31. Further, the arrangement surface 31 is preferably inclined at an intersection angle α of 70 to 80 degrees with respect to the installation surface 17, so that the endoscope 20 in the washing tub 30 is arranged in a state where it is suspended from the fixed rack 50. It will be in the form of lying on the surface 31. Since the placement surface 31 is suspended in a lying state, the endoscope 20 can be prevented from falling downward due to its own weight.

  5 and 6, when the fixed rack 50 is removed, the placement surface 31 of the upper area 30A of the washing tub 30 guides the fixed rack 50 to fix the endoscope 20 at a predetermined position. A guide groove 120 is formed. The guide groove 120 includes a first groove 121 having a shape corresponding to the operation portion 21 of the endoscope 20 and a second groove 122 having a shape corresponding to the connector portion 22.

  The guide groove 120 has a depth of about 0.5 to 1.5 mm. By forming the guide groove 120 on the arrangement surface 31, an operator who uses the product for the first time does not hesitate without checking the product manual or the like, and connects the operation unit 21 and the connector unit 22 according to the guide groove 120. Thus, the endoscope 20 can be fixed to the fixed rack 50. Although the guide groove 120 corresponding to the insertion portion 23 of the endoscope 20 is not formed, a third fixing portion (fixing tool) 60 to fix the insertion portion 23 can attach and detach a thin rod-like member. Since it has an attachment / detachment mechanism by a so-called push catch method for holding, the operator presses and fixes the thin rod-shaped insertion portion 23 from the front to the third fixing portion without being lost even if there is no guide groove or the like. be able to. Note that the guide groove 120 may not be a groove shape but may be a protrusion protruding from the arrangement surface 31 as long as the operator can guide the arrangement position of the endoscope 20 to the operator.

  On the upper area 30 </ b> A side of the arrangement surface 31, a step portion 36 and an upper wall portion 37 extending upward from the step portion 36 are provided. In the upper wall portion 37, the water sampling port 130 and the cassette 131 are arranged in the width direction X in order from the side surface 7 side to the side surface 6 side. The water sampling port 130 is an opening for sampling the electrolyzed water generated in the apparatus main body 10, and a cup 137 for storing the sampled electrolyzed water is disposed below the water sampling port 130. . The cassette 131 is a water supply / brush insertion tube to which a flexible first connection tube 141 for sending cleaning means such as cleaning water and a cleaning brush to the operation unit 21 of the endoscope 20 via the adapter 150 is connected. There is a road mouthpiece 131a. On the side surface 6 side of the cassette 131, a coupling 132a for passing through the cleaning tank 30 and stopping the coupler of the second connection tube 142 is located.

  Referring to FIGS. 4 and 5, in a state where the endoscope 20 is suspended from the fixed rack 50, the operation unit 21 of the endoscope 20 is located obliquely with respect to the vertical direction Y and the width direction X in the upper region 30 </ b> A. The flat operation panel surface on which the water supply button and the suction button are set is disposed so as to face the cassette 131 and the coupling 132a located above the step portion 36. Therefore, the adapter 150 to which the first and second connection tubes 141 and 142 extending from the pipe cap 131a and the coupling 132a of the cassette 131 can be easily attached to the operation panel surface of the operation unit 21.

  Below the coupling 132a, a water supply / air supply port 133 to which a third connection tube 143 for sending washing water and air is connected to the distal end portion 21b side of the operation unit 21 is located. The third connection tube 143 is connected to the operation unit 21 via the adapter 151. Further, below the water supply / air supply port 133, as an option, a water supply port 134 to which a sub-water supply tube (fourth tube) for sending out the cleaning water to the sub-water supply channel of the endoscope 20 is connected, and a cleaning device. An air supply port 135 for sending out air for removing the cleaning water remaining in the endoscope 20 later is located. A brush insertion opening 136 for cleaning the cleaning brush is located below the first groove 121.

  The second groove 122 of the guide groove 120 is located at a raised portion 139 that is raised forward, and the injection nozzle 35 c is located at a side portion of the raised portion 139 and jets washing water toward the second side wall portion 34. To do. As described above, since the raised portion 139 is positioned on the arrangement surface 31, for example, the washing water sprayed from the jet nozzles 35 b and 35 a hits the raised portion 139 and disperses, and the washing water is spread over a wider range beyond the jetting area. Can be indirectly sprayed onto the endoscope 20. The raised portion 139 has a concave curved portion 139a extending obliquely with respect to the vertical direction Y. The distal end portion 21b of the operation portion 21 of the endoscope 20 fixed to the fixed rack 50 is positioned in the concave curved portion 139a. When the raised portion 139 protruding forward is located on the arrangement surface 31, it can be said that the washing water is guided downward along the raised portion 139.

  A locking portion 38 for locking the fixed rack 50 is located on the front end edge side of the step portion 36. The locking portion 38 is formed of a plurality of locking pieces spaced forward from the step portion 36 and extending upward, and a plurality of notches 38a, which are spaced apart in the width direction X between the locking pieces. 38b and 38c are located. The fixed rack 50 is suspended in the washing tub 30 by engaging the U-shaped upper end frame 50a so as to be hooked on the notches 38a and 38c. The operator can easily remove the fixed rack 50 from the apparatus main body 10 by inserting a finger into the relatively wide notch 38b and lifting the upper end frame 50a upward.

  Since the fixed rack 50 is separate from the apparatus main body 10 and is disposed so as to be hooked on the stepped portion 36, the arrangement work can be easily performed. Further, since the fixed rack 50 is not integrally formed with the apparatus main body 10, it is possible to take out only the fixed rack 50 and replace or repair it. Furthermore, a fixed rack 50 having a design different from the illustrated example can be appropriately selected and used according to the size and shape of the endoscope 20 to be cleaned.

  The apparatus main body 10 has a side space (undercut portion) 138 located inside the first side wall portion 33. The side space 138 is a space formed on the rear side of the first side wall portion 33 and communicates with the washing tub 30 through a side opening defined by the side opening edge portion 138a. By forming the side space 138, the storage volume of the washing tub 30 can be further increased from the portion that opens and is exposed from the side opening edge 138a.

  In a state where the endoscope 20 is suspended from the fixed rack 50, a part of the first and second cord portions 24 and 25 of the endoscope 20 is located in the side space 138. When the storage volume of the washing tub 30 is small, there is a possibility that a part of the first and second cord portions 24 and 25 contacts the first side wall portion 33 and is forcibly bent to cause damage. Since the side space 138 is formed and the arrangement space of the endoscope 20 is increased, a part of the first and second cord portions 24 and 25 comes into contact with the first side wall portion 33 and is forcibly bent. There is no. Moreover, since the injection nozzle 35g for washing the 1st and 2nd code | cord | chord parts 24 and 25 is provided above the inside of the side space 138, the 1st and 2nd code | cord | chord part located in the side space 138 is provided. 24 and 25 can also be washed by directly spraying the washing liquid.

  Further, the folding preventing portion located at the base of the first and second cord portions 24 and 25 of the endoscope 20 is located opposite to the side opening edge portion 138 a of the first side wall portion 33. The side opening edge portion 138a has a curved cross section, and the corner portion 138b located on the front side is chamfered, so that the folding portions of the first and second cord portions 24 and 25 are in contact with the corner portion 138b. Even if it is a case, it can suppress that a bending prevention part is damaged.

  Referring to FIG. 4, for example, when the separation dimension (width dimension of the washing tub 30) W4 in the width direction X between the side wall portions 33 and 34 of the washing tub 30 is 250 to 350 mm, the width direction of the side space 138 The dimension W5 of X is preferably 80 to 180 mm. In such a case, the first and second cord portions 24 and 25 can be suspended in a state where the first and second cord portions 24 and 25 are gently bent so as to form an arc having an inner diameter of 330 to 530 mm. On the other hand, when the total length of the endoscope 20 is relatively small, the first and second cord portions 24 and 25 are U-shaped in the washing tub 30 located between the first and second side wall portions 33 and 34. It is arranged in a state of hanging in a shape.

  The apparatus main body 10 includes a process of cleaning the outside and the inside of the endoscope 20, a process of disinfecting, a rinsing process, and an air supply process in addition to the process of generating electrolyzed water used for cleaning and disinfection. Briefly describing each process, first, after setting the endoscope 20 in the fixed rack 50, the first to third connection tubes 141 to 143 are attached to the operation portion 21 and the connector portion 22 via the adapters 150 and 151. Let In the washing process, tap water or electrolyzed water is jetted from the jet nozzles 35a to 35h to wash the outer surface of the endoscope 20, and tap water and strong alkaline electrolyzed water are fed from the connection tubes 141 to 143 into the endoscope 20. Start automatic brushing with a cleaning brush while feeding water to each channel.

  Next, as a disinfection step, disinfecting liquid is ejected from the ejection nozzles 35a to 35h, and strongly acidic electrolyzed water is fed from the connection tubes 141 to 143 to disinfect each channel in the endoscope 20. Next, in the rinsing step, tap water is jetted and fed from the jet nozzles 35a to 35h and the connection tubes 141 to 143 to wash away the disinfectant solution. Finally, in the air feeding step, the inside of the endoscope 20 is washed away. When air is blown onto the water, moisture is blown off and water inside is pushed out.

  Note that the strongly acidic electrolyzed water generated in the apparatus body 10 may not be sufficiently sterilized due to the presence of organic substances such as blood and filth, but the automatic brushing function and strong alkaline electrolysis by the cassette 131 are not possible. By utilizing water, it has been able to cope with such a decrease in the bactericidal effect, and against many bacteria and viruses such as Helicobacter pylori contained in the gastric mucosa, hepatitis virus contained in blood, and anaerobic spore bacteria present in Escherichia coli. It can exhibit antibacterial and antiviral effects.

  Moreover, since strongly acidic electrolyzed water and strong alkaline electrolyzed water can be produced | generated from the additive liquid comprised from the additive (salt) with which the addition bottle 15 was filled, and water (tap water, purified water), it is conventional. It can be said that a sufficient sterilizing effect can be exhibited at a lower cost than in the case of washing and disinfecting using an expensive drug.

  The cleaning brush is driven by the cassette 131 and moves so as to be able to advance and retreat through each channel in the endoscope 20, and automatic brushing is controlled by a program installed in a computer control unit in the apparatus body 10. Reliable and uniform cleaning and disinfection work can be performed. The forward and backward movement of the cleaning brush is controlled according to the mode for cleaning and disinfecting the short upper gastrointestinal endoscope (inner diameter 2.0 to 3.7 mm) and the mode for cleaning and disinfecting the long colonoscope. ing.

  Although not shown, a float switch for detecting the amount of washing water in the washing tub 30 and detecting a drainage error is arranged in the washing tub 30. It is preferable to provide a float switch cover in order to prevent the float switch from malfunctioning when washing water is jetted from the jet nozzles 35a to 35h.

  The second fixing portion 52 of the fixed rack 50 includes an engaging portion 52a that protrudes in a curved shape from the lower end of the first side frame 50c, and a pair of sandwiching portions 52b that are positioned obliquely opposite each other in the width direction X. 52c.

  The fixture 60 of the fixed rack 50 is a push catch type fixing means for detachably fixing the insertion portion 23 of the endoscope 20, and is attached to the lower side of the second side frame 50 d and forward. It has a support member 61 made of metal or hard synthetic resin protruding in a bifurcated manner, and an elastic holding member 63 attached to the support member 61 via a shaft pin 62.

  The holding member 63 includes a pair of arm portions 64 and 65 that are rotatably supported via the shaft pin 62, a belt portion 66 positioned so as to cross between the arm portions 64 and 65, and a front surface of the arm portion 64. And a holding surface 67 defined by the front surface of the belt portion 66. The holding surface 67 has a plurality of protrusions 68 that are positioned at intervals in the length direction. The support member 61 is joined by bonding or welding so as to have a required joining strength at the intersection between the second side frame 50d and the lower end frame 50b.

  In the fixture 60, by pressing the thin rod-shaped insertion portion 23 against the central portion of the belt portion 66, the pair of arm portions 64 and 65 pivot toward the center so that their front surfaces face each other. The belt portion 66 is elastically deformed, and the insertion portion 23 is held by the belt portion 66. The detailed configuration of the fixture 60 will be described later.

  When the operator holds the endoscope 20 for setting in the washing tub 30, for example, the operator holds the tip of the operation unit 21 and the connector unit 22 with the right hand, and first and second with the left hand. The cord portions 24 and 25 are bundled and held in a state where they are overlapped with each other. As another aspect of gripping the endoscope 20, the operating portion 21 and the connector portion 22 are gripped by the right hand, and the insertion portion 23 is held by the left hand while the first and second cord portions 24 and 25 are suspended. Grip. In any aspect, the operator needs to hold the operation unit 21 and the connector unit 22 together with the right hand (one hand).

  When an operator places the endoscope 20 on the fixed rack 50 while standing in front of the endoscope cleaning apparatus 10, first, the operation unit 21 grasped together with the connector unit 22 with the right hand is inclined with respect to the arrangement surface 31. In this way, the base end portion 21a of the operation portion 21 is locked to the hook portion 51a and the distal end portion 21b is disposed on the support portion 51b. As described above, the operation unit 21 is disposed on the first fixing unit 51 simply by pressing the operation unit 21 against the first fixing unit 51 while maintaining the state where both the operation unit 21 and the connector unit 22 are held with the right hand. Therefore, there is no possibility of dropping the connector part 22 when the operation part 21 is arranged.

  The operation portion 21 is positioned obliquely with the base end portion 21a being locked to the hook portion 51a in the first fixing portion 51, so that the base end portion 21a is further stabilized to the hook portion 51a by its own weight. Can be locked. Moreover, since the hook part 51a has the shape which protruded ahead in the U shape, it can prevent that the operation part 21 falls forward.

  When the first fixing portion 51 is only the hook portion 51a, the entire operation portion 21 hangs down, and the tip portion 21b may interfere when the connector portion 22 is disposed on the second fixing portion 52 below. is there. In the present embodiment, the operation portion 21 is supported at two points, that is, the hook portion 51 a and the support portion 51 b of the first fixing portion 51, so that the operation portion 21 is not positioned downward, and the connector portion is connected to the second fixing portion 52. There is no risk of interference when placing 22. In addition, as long as the operation part 21 can be detachably fixed using its own weight, the shape of the hook part 51a and the support part 51b of the 1st fixing | fixed part 51 may differ from the example of illustration.

  After fixing the operation part 21 to the first fixing part 51, the operator places the connector part 22 held with the right hand on the second fixing part 52 located below the first fixing part 51. Deploy. Specifically, the connector part 22 is directed to the second fixing part 52 in a state where the connector part 22 is held obliquely so as to be parallel to the operation part 21 arranged in the first fixing part 51, and the connecting portion 22 a of the connector part 22 is connected. Is pressed against the hook-shaped locking portion 52a. Thereby, the connecting portion 22a is supported by the locking portion 52a from below. Since the tip of the locking portion 52a is curved, the connector portion 22 is not damaged even if it contacts the tip.

  At the same time that the connecting portion 22a is locked to the locking portion 52a, the proximal end portion 22b of the connector portion 22 is pressed so as to be inserted between the pair of sandwiching portions 52b and 52c. As a result, the base end portion 22b is fitted into the gap between the pair of sandwiching portions 52b and 52c, and is supported from above and below. More specifically, the connection portion 22a comes into contact with the sandwiching portions 52b and 52c and the base end portion of the connector portion 22 locked to the locking portion 52a is about to fall to the side surface 6 side by its own weight. 22b is blocked by being fitted between the sandwiching portions 52b and 52c.

  Thus, in the 2nd fixing | fixed part 52, the connector part 22 is supported from the upper side and the lower side by the latching | locking part 52a and clamping part 52b, 52c, and is stably fixed in the clamped state. . In the connector portion 22, the connection portion 22a and the base end portion 22b are stably locked with the locking portion 52a and the clamping portions 52b and 52c, respectively, so that the fixed rack 50 or the apparatus main body 10 has a strong external impact. Even if it receives, there is no possibility that the fixing by the fixture 60 is released and the connector part 22 falls downward or forward.

  The operator holds the operation unit 21 and the connector unit 22 with the right hand and fixes the operation unit 21 to the first fixing unit 51 with a single touch, and then moves the second position directly below without changing the handle. Since the connector part 22 can be fixed to the fixing part 52 at a position parallel to the operation part 21, the placement operation can be performed smoothly with only one hand.

  After fixing the connector portion 22 to the second fixing portion 52, the operator extends the insertion portion 23 held by the left hand in the vertical direction Y, that is, the central portion of the holding surface 67 of the third fixing portion 60, that is, The arm portion 64, 65 is rotated so that the front surfaces of the arm portions 64, 65 face each other by pressing against the central portion of the belt portion 66 toward the front surface, and the insertion portion 23 is held by the holding surface 67. Be held.

  As described above, the operator removably fixes the operation unit 21, the connector unit 22, and the insertion unit 23 of the endoscope 20 to the fixed rack 50 with one touch on the first to third fixing units 51, 52, and 60, respectively. And a quick set of the endoscope 20 is possible. In addition, since the first and second cord portions 24 and 25 can be fixed in a suspended state, a conventional flat-type endoscope washing apparatus that is arranged so as to wrap each cord around a flat-fixed rack. As compared with the above, the endoscope 20 can be easily and smoothly arranged in the washing tub 30. Further, by supporting the main components 21, 22, 23 at three points via the first to third fixing parts 51, 52, 60 in a state where the endoscope 20 is suspended from the arrangement surface 31, It can fix more stably compared with the case where only any one or two of the component parts 21, 22, and 23 are supported.

  Referring to FIG. 8, the width dimension L3 of the portion of the hook portion 51a of the first fixing portion 51 bent in a U-shape is 15 to 25 mm. When the width dimension L3 is 15 mm or more, the proximal end portion 21a of the operation portion 21 can be stably held and prevented from falling forward. Moreover, the length dimension L4 of the part which connects the hook part 51a and the support part 51b among the crossing frames 50e is 80-120 mm. When the length L4 is 80 mm or more, the operator puts his hand between the hook part 51a and the support part 51b protruding forward and puts them between them, and the operation part 21 of the endoscope 20 is reached. Can be placed and removed.

  The fixed rack 50 is formed by bending a single wire, and the bent portions are all curved and do not have a portion having a sharp shape (pin shape). Therefore, when the endoscope 20 is arranged on the fixed rack 50, there is no possibility that a part of the endoscope 20 is caught or even if the first and second cord parts 24 and 25 are in contact with each other.

  The fixed rack 50 is preferably formed by coating a metal wire with a synthetic resin. For example, a stainless steel wire (wire diameter: 4.0 mm) coated with a polyethylene resin can be suitably used. . By using stainless steel instead of iron as the wire rod, the first and second cord portions 24 and 25 of the endoscope 20 are fixed to the fixed rack 50 by coating with synthetic resin. Even if it contacts, it can suppress that it breaks. In addition, for example, when the operator performs a rough arrangement operation so that the operation unit 21 is dropped on the first fixing unit 51 from above, when the operation unit 21 is received by the first fixing unit 51 Although a strong impact is given, the fixed rack 50 can withstand such an impact. For example, when the operation unit 21 having a mass of 800 g is dropped from 40 mm above the first fixed unit 51, the impact (120N) is received. Has strength to withstand.

  In the present embodiment, the fixed rack 50 is formed from one continuous wire, but a plurality of wires may be joined by a known bonding or welding means. In addition, when using a plurality of wire rods, materials having different properties such as material and fineness may be used in consideration of tensile strength required for each portion. Furthermore, the shapes of the first to third fixing portions 51, 52, 60 of the fixed rack 50 can be appropriately changed according to the shape of the endoscope 20.

Both end portions 72 and 73 have side walls 72c and 73c that are bent from the support member 61 and extend forward, and upper and lower walls 72a, 72b, 73a, and 73b that face each other in the vertical direction Y, respectively. The upper walls 72a, 73a and the lower walls 72b, 73b of the both end portions 72, 73 have through holes 74a, 74b, 75a, 75b facing each other in the vertical direction Y.

  The holding member 63 includes a pair of arm portions 64 and 65, and a belt portion 66 that is coupled to the pair of arm portions 64 and 65 and extends in the width direction X. The arm portions 64 and 65 have base end portions 64A and 65A extending rearward from the belt portion 66, and convex curved tip portions 64B and 65B. The arm portions 64 and 65 are gradually narrowed from the base end portions 64A and 65A to the tip end portions 64B and 65B, and are positioned at the base end portions 64A and 65A so that they are arranged in the thickness direction (vertical direction Y). A plurality of through-holes 78 penetrating into the top end portions 64B and 65B and pin insertion holes 79 penetrating in the vertical direction Y.

  Referring to FIGS. 10 and 11, the belt portion 66 is formed of a flexible material, for example, an elastic material such as soft synthetic resin, synthetic rubber, natural rubber, or the like. Between the edges 66a and 66b, both side edges (upper and lower edges) 66c and 66d extending in the length direction, a base portion 80 extending in a strip shape, and a predetermined interval in the length direction of the base portion 80 projecting forward from the base portion 80 are provided. And a plurality of protrusions 68 arranged.

  The belt portion 66 (or the holding member 63) includes a central axis P that bisects the dimension in the width direction of the holding surface 67, a first section 181 that is located inside the width direction X from the central axis P, and the central axis P To a second area 182 located outside in the width direction X. In the present embodiment, the holding member 63 has a symmetric shape with respect to the central axis P, but may have an asymmetric shape with respect to the central axis P as long as the technical effect according to the present invention is achieved. .

  The arm portions 64 and 65 of the holding member 63 are inserted from the front into the space between the upper and lower walls 72a, 72b, 73a and 73b of the both end portions 72 and 73 of the support member 61. The shaft pins 62 that pass through the through holes 74a, 74b, 75a, 75b of 72b, 73a, 73b and the pin insertion holes 79 of the arm portions 64, 65 are connected to the support member 61 by caulking or press-fitting. The holding member 63 is slightly bent toward the central axis P so that the front surfaces of the arm portions 64 and 65 face each other in a state where the holding member 63 is connected to the support member 61 via the shaft pin 62. Has a curved shape as a whole.

  The support member 61 of the third fixing portion 60 is joined to the main body portion of the fixing rack 50 by welding, and is formed from a stainless steel sheet coated with a synthetic resin (for example, polyethylene resin). The shaft pin 62 may be made of metal, but is preferably made of synthetic resin (for example, polypropylene resin). When the shaft pin 62 is made of a synthetic resin, even a female worker can insert through holes 74a, 74b, 75a, 75b in the upper and lower walls 72a, 72b, 73a, 73b and the pin insertion holes in the arm portions 64, 65. It is preferable that the shaft pin 62 has a flexibility that allows the shaft pin 62 to pass through the shaft 79. The holding member 63 can be formed of a soft elastic material such as fluoro rubber or silicon resin, but is preferably formed of silicon resin in consideration of wear resistance. As described above, the entire outer surface of the fixture 60 is formed of a synthetic resin as a whole, so that a part of the endoscope 20 can be prevented from coming into contact with the fixture 60 and being damaged.

  Referring to FIG. 11, the plurality of protrusions 68 of the belt portion 66 are formed symmetrically with respect to the central axis P, and the first and second sections 181 and 182 have both edges 66a and 66b from the central axis P, respectively. Five protrusions 68a, 68b, 68c, 68d, 68e lined up toward are located. The protrusion 68 has a base end portion extending from the base portion 80 and a tip end portion extending in a tip shape from the base end portion.

  The length dimension W6 of the belt portion 66 can be appropriately changed depending on the size of the endoscope 20 to be used. For example, when the length dimension W6 is 60 to 70 mm, the distance between the protrusions 68a, 68b, and 68c. The separation dimensions R1 and R2 are 0.5 to 2.0 mm, and the separation dimension R3 between the outermost protrusion 68e and the adjacent protrusion 68d is larger than the separation dimensions R1 and R2, and 2.1 to 4.0 mm. In addition, a separation dimension R4 between the protrusion 68a located in the innermost portion of the first area 181 and the protrusion 68a located in the innermost area of the second area 182 through the central axis P is 7.0 to 10.0 mm. is there. Accordingly, the separation dimension R4 is larger than the separation dimension R3 between the protrusions 68d and 68e, and the separation dimension R2 between the protrusions 68b and 68c.

  Regarding the height dimension of each of the protrusions 68a to 68e, the height dimension of the innermost protrusion 68a is larger than the height dimension of the other protrusions 68b to 68e in the first and second sections 181 and 182. ing. In addition, the height dimension of the protrusion 68d adjacent to the inside of the protrusion 68e located at the outermost position is smaller than the height dimension of the other protrusions 68a to 68c, 68e. Here, the height dimension of the protrusions 68a to 68e means a separation dimension from the base part of the base end part to the apex of the tip part. For example, referring to the enlarged view, the base of the base end part 84b of the protrusion 68e is shown. The height dimension H1 from the portion (the portion in contact with the base portion 80) to the apex 84a of the tip end portion 84 is meant.

  Referring to FIGS. 12A and 12B, the arm portion 64, 65 is positioned at the center of the shaft pin 62 by pressing the insertion portion 23 of the endoscope 20 against the central portion of the holding surface 67. It turns inward in the width direction X around T2. As the arm portions 64 and 65 pivot, the front surface of the base end portion 64A and the front surface of the base end portion 65A face each other so that the belt portion 66 protrudes backward while holding the insertion portion 23. Transforms into

  The insertion portion 23 of the endoscope 20 is held while being in contact with the tips of the plurality of protrusions 68a to 68e in a holding space (first holding space) S1 defined by a holding surface 67 surrounding the outer periphery. The

  Referring to FIG. 12A, the wire diameter of the insertion portion 23 is 9.0 to 14.2 mm, and the outer diameter dimension of the insertion portion 23 is formed by a plurality of protrusions 68a to 68e surrounding the outer periphery. Since the inner diameter dimension of the space S1 is larger, the protrusions 68c and 68d among the protrusions 68a to 68e are in contact with the insertion portion 23 and are buckled and deformed. The protrusions 68c and 68d of the first section 181 and the protrusions 68c and 68d of the second section 182 that are located facing each other in the circumferential direction of the insertion section 23 are buckled and deformed, and the elastic restoring force acts toward the insertion section 23. As a result, the insertion portion 23 is stably held on the holding surface 67. Since the belt portion 66 and the protrusions 68a to 68e can be elastically deformed, even if the cross-sectional shape of the insertion portion 23 is elliptical, triangular, or rectangular, it can be stably held.

  Thus, in order for the projections 68c and 68d defining the holding space S1 to abut on the insertion portion 23 and to buckle and deform, it is necessary that the projections 68c and 68d have the required height dimension H1. The height dimension H1 is at least 4.0 cm or more, preferably 4.0 to 6.0 cm. Further, when the insertion portion 23 is pressed against the holding surface 67, the protrusions 68c and 68d are elastically deformed so as to bend backward from the base end portion 84b, and the elastic restoring force is pushed so as to push the insertion portion 23 forward. In order to prevent it from acting, it is preferable that the base end portion 84b of the protrusion 68 has a predetermined width dimension W7 of at least 1.5 cm and 1.5 to 2.2 cm (see FIG. 11). ).

  When removing the insertion portion 23 from the third fixing portion 60, the arm portions 64 and 65 rotate around the axes T1 and T2 so that they are separated from each other by holding the insertion portion 23 and pulling it forward. Then, the belt portion 66 returns to the state before the insertion portion 23 is held.

  Referring to FIG. 13A, when the wire diameter of the insertion portion 23 of the endoscope 20 is 4.9 to 9.0 mm and is relatively small, the insertion portion 23 is positioned at the center of the holding surface 67. It is held in a state where it is located in the separating portion 77. In other words, the holding space (second holding space) S2 formed between the protrusions 68a and 68a located on the innermost sides of the first and second sections 181 and 182 is held so as to be sandwiched between the protrusions 68a and 68a.

  As described above, since the third fixing portion 60 has the push catch type attachment / detachment mechanism, the insertion portion 23 can be quickly set with one hand, and a plurality of the third fixing portions 60 can be set in accordance with the wire diameter of the insertion portion 23. Since the holding spaces S1 and S2 are provided, the insertion portion 23 having various shapes can be stably held.

FIG. 16A is a view similar to FIG. 14 showing a state in which the panel 41 is swung, FIG. 16A is a view showing a state in which the fourth door panel 44 is moved upward, and FIG. FIG. 16 (c) is a diagram illustrating a state in which the upward movement is stopped and the door is opened, FIG. 16 (c) is a diagram illustrating a state in which the door body 40 starts closing, and FIG. FIG. 17B is a partially enlarged view surrounded by the alternate long and short dash line XVII in FIG. 17A, and FIG. 18 is a partially enlarged view of the region surrounded by the alternate long and short dash line XVIII in FIG. is there. With reference to FIGS. 14-18, the detailed structure of the door body 40 is demonstrated below.

Referring to FIGS. 14 and 15, the door body 40 is a foldable type, and includes a pivot shaft 91 positioned on the upper surface side and extending in the width direction X, and a pair of hinge portions 92 </ b> A to 92 </ b> C facing each other in the width direction X. And a plurality of door panels 41 to 44 that are pivotably connected to each other. On the inner surface side of the both side wall portions 33 and 34 of the washing tub 30, the plurality of door panels 41 to 44 constituting the door body 40 are moved in the vertical direction from the lower wall portion 32 to the upper surface 4 side in order to move in the vertical direction Y. A metal guide rail 90 extending continuously to Y is disposed (see FIGS. 2 and 6). The guide rail 90 extends gently downward from the vicinity of the step portion 36 on the inner surface side of the side wall portions 33, 34 of the apparatus main body 10. The swivel shaft 91 is a metal rod having a required strength. For example, the maximum shear stress is 20 to 30 N / mm ² and the bending stress is 25 to 35 Nmm ² .

  The plurality of door panels 41 to 44 of the door body 40 are arranged from the upper side to the lower side in the closed state, the first door panel (upper stage) 41, the second door panel (upper middle stage) 42, and the third door panel (lower middle stage). 43 and a fourth door panel (lower stage) 44. In this embodiment, although the door panels 41-44 are divided | segmented into four, you may be divided | segmented into it below or more. However, in consideration of the turn order of the door panel, forward protrusion during turning, and the like, it is preferable that the door panel is divided into an even number such as four, six, eight, etc. Depending on the size of the opening 30a of the apparatus main body 10, the number of divided panels and the size of each door panel can be selected freely.

  In the case of so-called left-opening, right-opening, or double-speech opening in which the door body 40 opens to the left or right side with respect to the apparatus main body 10, the door is opened when the apparatus main body 10 is disposed near the indoor wall. It is not possible to secure enough space for opening. In the apparatus main body 10 according to the present embodiment, the door body 40 moves upward while the door panels 41 to 44 turn and is folded on the upper surface 4 of the apparatus main body 10. A space for opening the door body 40 is not required in the front and the side.

  The automatic opening and closing time of the door body 40 is about 5 to 8 seconds, and the door is opened and closed by a relatively slow operation. Therefore, even if the operator mistakenly inserts a finger into the gap between the door panels 41 to 44, the finger can be extracted before the finger is pinched.

  Here, in this specification, “the door 40 is in a closed state (completely closed)” means that the fourth door panel 44 is positioned adjacent to the fixed panel 45 in the vertical direction Y, and is washed by the door 40. It means that the opening 30a of the tank 30 is completely closed. On the other hand, “the door body 40 in the open state (completely open)” is located on the upper surface 4 side of the apparatus body 10 in a state in which the door panels 41 to 44 of the door body 40 are folded. This means that 30a is completely opened and the entire washing tub 30 is exposed to the outside.

  The door panels 41 to 44 are box-shaped and have a top wall that constitutes a part of the front surface of the apparatus main body 10, an upper wall, a lower wall, and both side walls extending between the upper and lower walls. Referring to FIG. 17A, for example, the fourth door panel 44 has a top wall 44a, upper and lower walls 44b and 44c, and both side walls 44d and 44e, and the other door panels 41 to 43 have the same configuration. . Since the door panels 41 to 44 have a three-dimensional box shape, the top wall is located farther from the arrangement surface 31 of the washing tub 30 than when it is a flat plate, and the washing tub is opened and closed during the opening and closing movement. There is no contact with the endoscope 20 disposed in the 30.

  The door panels 41 to 44 are made of a hard plastic material such as acrylic, hard vinyl chloride, or acrylic-modified polyvinyl chloride, and are transparent or translucent so that the endoscope 20 disposed inside can be seen through. It is. The door panels 41 to 44 may have various known shades such as red, blue, and green. However, the door panels 41 to 44 are preferably black in order to make the yellowing due to water scale or aging deterioration as inconspicuous as possible. . Further, it is preferable to apply a texture to the both side walls of the door panels 41 to 44 in order to make the wiping residue of water droplets inconspicuous.

  Between the upper and / or lower walls of the door panels 41 to 44 facing each other, rubber is used to prevent the cleaning water sprayed from the spray nozzles 35a to 35h from leaking into the cleaning tank 30 to the outside. Packing is arranged. Further, the upper wall / or the lower wall of the door panels 41, 44 facing each other and partially overlapping each other is not horizontal with respect to the installation surface 17 and is slightly inclined rearward. Thus, in the upper wall and the lower wall of the door panels 41 to 44 facing each other, only a slightly inclined surface is formed with respect to the installation surface 17 without forming a horizontal plane, so that between the two walls. It is possible to prevent the washing water that has entered from moving backward along the slope and flowing into the washing tub 30 so that the washing water stays between both walls and adheres to scales and the like.

  Referring to FIG. 17A, the hinge portion 92 </ b> A that connects the lower wall of the first door panel 41 and the upper wall of the second door panel 42, the lower wall of the third door panel 43, and the fourth door panel 44. The hinge portion 92C connecting the upper wall supports these panels so as to be rotatable. On the other hand, the second and third door panels 42, 43 are rotatably connected to the hinge portion 92 </ b> B that connects the lower wall of the second door panel 42 and the upper wall of the third door panel 43, and the guide rail 90. A slider 94 is slidably moved inside.

  Both side walls of the second and third door panels 42 and 43 have connecting portions that are recessed inward in the width direction X, and the connecting portions that face each other are overlapped. The slider 94 includes a fixing portion 94 a fixed through a shaft pin inserted through a pin insertion hole that passes through the connecting portions that are overlapped with each other, and a sliding contact portion 94 b that is slidably contacted with the guide rail 90. The sliding contact portion 94b of the slider 94 is rectangular in plan view, and no roller is attached to the bottom surface. Therefore, when the guide rail 90 is moved from the lower side to the upper side, the corner portion 70a that is bent and extended toward the upper surface 4 side of the guide rail 90 may be detached from the guide rail 90. The portion 90a is formed wider than the other portions, and there is no possibility that the slider 94 comes off at the corner portion 90a when the door body 40 is closed.

  A roller 95 movable within the guide rail 90 is attached to the lower end of the fourth door panel 44. The door body 40 has such a configuration so that the first to fourth door panels 41 to 44 can be folded when the door body 40 (first door panel 41) rotates around the axis of the rotation shaft 91. The guide rail 90 can be moved via the slider 94 and the roller 95. Locking hooks 95a and 95b for locking both ends of the wire are located at the lower end of the fourth door panel 44. When the wire is locked to the locking hooks 95a and 95b, the door body 40 can move upward along with the endless circulation movement of the wire.

  Referring to FIG. 15, the door body 40 further includes a drive mechanism for opening and closing the door body 40. The drive mechanism is rotated by the motor 81, a motor 81 serving as a power source, a plurality of guide rolls 82 a to 82 c that are disposed on both sides of the apparatus main body 10 and are arranged to transmit power from the motor 81. As described above, the wire rope 83 is supported by the plurality of guide rolls 82a to 82c so as to be capable of endless circulation. As the motor 81, an AC reversible motor capable of forward rotation and reverse rotation is preferably used.

  A timing belt 86 is attached to the wire rope 83 via connecting plates 85a and 85b. The motor 81 is attached to the mount member 87. In addition to the motor 81, the mount member 87 is provided with a timing pulley 88 driven by the rotation shaft V of the motor 81 and a pair of idlers 89a and 89b for adjusting the tension of the timing belt 86. A plurality of teeth having the number of teeth of the timing belt 86, the number of teeth corresponding to the tooth size, and the tooth size are formed on the outer peripheral surface of the timing pulley 88 so as to mesh with the teeth of the timing belt 86. In the present specification, the wire rope 83 and the timing belt 86 are also simply referred to as an annular wire.

  The wire is located in the guide member 190 that extends from the mount member 87 toward the upper surface 4 in the apparatus main body 10. The guide member 190 has a base wall portion extending in the length direction thereof, and both side wall portions standing from both side edges of the base wall portion. The wire is disposed in an internal space surrounded by the base wall portion and both side wall portions of the guide member 190.

  Since the wire moves in the guide member 190 by the drive of the motor 81, it is isolated from other electrical components in the apparatus main body 10, and the washing water adheres to the outer surface by moving in the washing tank 30. However, there is no possibility that the cleaning water adheres to the other electrical components by touching the other electrical components in the apparatus main body 10. Although not shown, a central wall may be formed between the wires that move in parallel in the internal space of the guide member 190 so as to prevent the wires from interfering with each other.

  The operation of the motor 81 is controlled by a computer control unit built in the apparatus main body 10. Although not shown in the figure, a detection sensor for detecting lifting when teeth jump may be arranged on the outer peripheral surface of the timing belt 86. For example, a micro switch or a distance sensor can be suitably used as the detection sensor, and the operation of the motor 81 can be controlled by the computer control unit in response to an output signal from the detection sensor.

  The pedal 9 protruding forward from the front surface of the lower portion of the apparatus main body 10 is mechanically connected to the motor 81 via a computer control unit. That is, when the operator steps on the pedal 9 in the closed state, the computer control unit issues a command to rotate the motor 81 in the forward direction (when the door is opened), the motor 81 is driven, and the door panels 41 to 41 are driven. 44 moves upward while turning. When the operator further steps on the pedal 9 during the upward movement of the door body 40, the movement of the door body 40 can be stopped.

  In addition, when the operator steps on the pedal 9 in the open state, the computer control unit instructs the motor 81 to rotate backward (when the door is closed), and the motor 81 is in the opposite direction to that when the door is opened. The door panels 41 to 44 move downward while turning. Therefore, the operator can freely open and close and stop the door body 40 by operating the pedal 9 without operating the liquid crystal touch panel, for example, holding the endoscope 20 in both hands. Even in the state, the door body 40 can be opened and closed.

  Referring to FIG. 15, the apparatus main body 10 includes a lower sensor 101 for detecting the position of the roller 95 attached to the lower end portion of the fourth door panel 44 in the closed state, and a fourth sensor in the opened state. An upper sensor 102 for detecting the position of the roller 95 of the door panel 44 is disposed. The upper and lower sensors 101 and 102 are magnetic sensors, and a magnet is built in a fixing member for attaching the roller 95 to the side wall portion of the fourth door panel 44. The exact position of the folded state and the lower end of the fourth door panel 44 can be detected.

  Referring to FIGS. 15 and 16, the first door panel 41 is connected to the apparatus main body 10 via damper means (gas damper) 188. Specifically, the damper means 188 has one end fixed to a fixing portion 187 a located in the apparatus main body 10 and the other end connected via a connecting portion 187 b attached to the side wall of the first door panel 41. It is fixed. By the damper means 188, the apparatus main body 10 and the door body 40 are connected by a link mechanism, and the damper means 188 urges the door body 40 in a turning direction.

  Since the damper means 188 is attached to the first door panel 41, when the door body 40 is turned around the axis of the turning shaft 91 when the door is opened, the first door panel 41 is moved to the other door panel 42. The turning is started before -44. In addition, the door body 40 is fully opened and fully closed by the force of the wire that circulates endlessly. However, when the force by the wire is not applied, the first door panel 41 is half-opened by the biasing force of the damper means 188. It becomes a state. When the door is opened, the first door panel 41 starts turning before the other door panels 42 to 44.

  Since the door body 40 is connected to a wire that circulates endlessly via a locking hook 95a located at the lower end of the fourth door panel 44, when the turn starts from the fourth door panel 44 in order upward, The higher the position is, the more the loads of the lower door panels 42 and 43 are applied to the door panels 41 to 43, making it difficult to pull them up. In addition, when the door panels 41 to 44 turn in order from the lower side, the door panels 41 to 44 may protrude forward and interfere with the operator. In the door body 40 which concerns on this embodiment, since it turns from the 1st door panel 41 located upwards, this disadvantage can be prevented.

  The operation when the door 40 is opened will be described. First, when the operator steps on the pedal 9 from the state where the door 40 is completely closed as shown in FIG. Start turning. Since the damper means 188 is attached to the first door panel 41, the first door panel 41 starts turning earlier than the other door panels 42 to 44 and rises upward. As the first door panel 41 rises, the second door panel 42 connected thereto via the hinge portion 92 </ b> A rises and moves upward by the slider 94 located in the guide rail 90. The third and fourth door panels 43 and 44 move upward without being folded over from each other while remaining in a substantially parallel state.

  In the door panels 41 to 44, the length dimension (dimension in the vertical direction Y) L6 of the second door panel 42 is larger than the length dimension L5 of the first door panel 41, and the length dimension L8 of the fourth door panel 44. Is larger than the length L7 of the third door panel 43.

  Referring to FIG. 16 (a), the inner surfaces of the first and second door panels 41, 42 are opposed to each other so that the first and second door panels 41, 42 are folded in the front-rear direction Z on the upper side of the apparatus body 10, and at the same time. A third door panel 43 connected to the second door panel 42 via the slider 94 turns and rises obliquely, and a fourth door panel 44 connected to the third door panel 43 via a hinge portion 92C. The roller 95 located in the guide rail 90 stands up diagonally while moving upward.

  Referring to FIG. 16 (b), the second door panel 42 is folded together with the first door panel 41 and maintained in a standing state when the door body 40 is in the opened state and folded. Since the guide rail 90 has a downwardly inclined shape on the upper side along the shape of the apparatus main body 10, the height dimension L6 of the second door panel 42 is equal to the height dimension L5 of the first door panel 41. If it is equal or smaller than that, the second door panel 42 is lower than the first door panel 41 in the open state, and the first door panel 41 is covered so that the second door panel 41 is overlaid. There is a possibility that the state in which the panel 42 is raised cannot be maintained and the entire door body 40 protrudes forward.

  In the present embodiment, since the height dimension L6 of the second door panel 42 is larger than the height dimension L5 of the first door panel 41, the first door panel 41 and the second door panel are folded in a mutually folded state. 42 can maintain an upright state. Thus, maintaining the state where the first and second door panels 41 and 42 are standing without falling forward does not give the operator a feeling of pressure, and the washing water adhering to the inner surface Since it moves downward, draining is improved.

  Similarly, the third and fourth door panels 43 and 44 that overlap each other are also folded together because the height dimension L8 of the fourth door panel 44 is larger than the height dimension L7 of the third door panel 43. In the state, the 3rd door panel 43 and the 4th door panel 44 can maintain the standing state.

  Referring to FIG. 16 (c), when the operator depresses the pedal 9 in the opened state, the roller 95 of the fourth door panel 44 moves downward to start the closing operation. 41 remains in an upright state, and the second door panel 42 is moved downward by the slider 94 so as to be separated from the first door panel 41. On the other hand, the third and fourth door panels 43 and 44 are in a state of being overlapped with each other and closed. When the second door panel 42 is further moved downward, the fourth door panel 44 is moved downward by the roller 95 so as to be separated from the third door panel 43 and is separated from the third door panel 43 and opened. Return to the closed state.

  As described above, the operation of the door body 40 can be stopped by stepping on the pedal 9 when the door is opened and when the door is closed. For example, in the computer control unit, the stop operation by the pedal 9 can be controlled in a closed state → wiping mode 1 → wiping mode 2 → opening state. In the wiping mode 1, as shown in FIG. 15, the first door panel 41 and the second door panel 42 are in an open state, and hands are inserted into the inner surface sides of the first and second door panels 41 and 42. As a result, water droplets and the like attached to the entire inner surface can be easily wiped off.

  On the other hand, the wiping mode 2 is a state in which the third door panel 43 and the fourth door panel 44 are open as shown in FIG. 16A, and the inner surfaces of the third door panel 43 and the fourth door panel 44. By inserting a hand into the side, water droplets and the like adhering to the entire inner surface can be easily wiped off. In the wiping modes 1 and 2, it is preferable to perform control so that the operation by the pedal 9 is invalid and only the liquid crystal touch panel 12 is operated in order to ensure safety.

  Since the door body 40 performs the opening / closing operation, the door body 40 does not protrude greatly forward from the front surface of the apparatus body 10 during opening / closing, and specifically, the front-rear direction Z of the portion protruding forward Is at least 150 mm or less, preferably 100 mm or less. According to the applicant's knowledge, when the worker is an adult, the worker opens and closes the operator 20 in a state where the endoscope 20 is separated from the apparatus main body 10 to such an extent that the endoscope 20 can be fixed to the fixed rack 50 by reaching. When the door 40 projects beyond 150 mm from the apparatus main body 10 at the time of the door, the door 40 may hit the worker's body. When the door 40 projects within the range of 100 to 150 mm, the worker It is possible to avoid the door body 40 from hitting by warping, and the door body 40 will not hit the body if it protrudes less than 100 mm. Moreover, the door body 40 is folded compactly in the open state, and specifically, the dimension W8 in the front-rear direction in the folded state is 260 mm or less.

  Referring to FIG. 18, a panel pressing portion 96 extending inward in the width direction X from the other portions is located on the lower side portions of the both side wall portions 33 and 34 of the washing tub 30. As described above, while the door body 40 is being closed, the third and fourth door panels 43 and 44 move in a parallel state until reaching the upper surface 4 side, thereby suppressing forward protrusion. Since the panel pressing portion 96 is positioned on the front side of the fourth door panel 44, the fourth door panel 44 can be more reliably suppressed from standing up before the other door panels. Further, when the door is closed, the fourth door panel 44 that moves downward can be prevented from being lifted, and the door can be smoothly closed.

  Behind the fixed panel 45 is a first abutment portion 97 made of a soft synthetic resin such as urethane rubber or silicone rubber, and a soft synthetic resin or a hard rigid resin located further rearward of the first abutment portion 97. A second abutting portion 98. When the endoscope 20 is disposed in the washing tub 30, a part of the endoscope 20, for example, the first and second cord parts 24 and 25 hanging down may come into contact with the lower end of the opening 30a. In such a case, the first and second cord portions 24 and 25 are not damaged by coming into contact with the flexible first contact portion 97.

  On the other hand, when the endoscope 20 is taken out from the washing tub 30 after washing, the first and second cord portions 24 and 25 are brought into contact with the second abutting portion 98 located further rearward (inner side) of the first abutting portion 97. Since they are in contact with each other and do not come into contact with the first contact portion 97 with which they come into contact before washing, they can be taken out from the washing tub in a clean state. Further, the second contact portion 98 protrudes upward from the first contact portion 97. Therefore, it is possible to avoid a part of the endoscope 20 taken out from the washing tub 30 from coming into contact with the first contact portion 97 after contacting the second contact portion 98.

And both side wall portions 205 and 206 facing each other. The bottom wall 202 of the bottle body has a stepped shape and has a cylindrical fitting protrusion 210 that protrudes downward. The fitting protrusion 210 has an opening, and a male spiral 211 is formed on the outer periphery thereof.

  An additive liquid (electrolysis auxiliary liquid) 250 composed of an additive (salt) and water for dissolving the additive is injected into the additive bottle 15. The additive liquid 250 is used as a stock solution for generating strongly acidic electrolyzed water and strongly alkaline electrolyzed water in the electrolyzed water generating step of the endoscope cleaning apparatus 10. The additive liquid 250 injected into the additive bottle 15 is stored in the bottle receiver 400, sucked by the pump via the liquid feeding tube 220, and sent to the mixing tank together with the purified water sent from the water purification tank by the pump. . After the purified water and the additive liquid 250 are mixed in the mixing tank, they are electrolyzed in the electrolytic tank to produce strongly acidic electrolyzed water and alkaline electrolyzed water. The generated electrolyzed water is respectively stored in an alkaline electrolyzed water tank and an acidic electrolyzed water tank, and a flow path from each tank to the injection nozzles 35a to 35h, the pipe cap 131a, the coupling 132a, and the water sampling port 130. Is controlled by a solenoid valve.

  Referring to FIGS. 19, 20 and 21, the lid 300 has a cylindrical outer peripheral wall portion 301 having a female spiral 311 on the inner periphery and a circular flat portion 302. The flat portion 302 of the lid 300 has an upper inner cylindrical wall portion (inflow prevention wall) 310 that protrudes upward so as to be surrounded by the outer peripheral wall portion 301 at the center portion of the inner bottom surface 302a, and an upper portion at the center portion of the outer surface 302b. A lower inner cylinder wall 320 extending downward is provided so as to face the inner cylinder wall 310 in the vertical direction Y. The upper and lower inner cylindrical wall portions 310 and 320 have open end portions 310a and 320a, respectively. A central hole 331 penetrating through the inner bottom surface 302a formed by the central portion of the flat portion 302 surrounded by the upper and lower inner cylindrical wall portions 310 and 320 and a plurality of water supply ports 332 arranged around the central hole 331 at substantially equal intervals. And are formed.

  The lid 300 further includes a check valve mechanism including a normally closed valve. The check valve mechanism includes a valve core 341 penetrating through the central hole of the lid, and a valve 342 attached to the sharp tip of the valve core 341. The outer diameter dimension of the valve 342 is larger than the outer diameter dimension of the valve seat including the open end portion 310 a of the upper inner cylindrical wall portion 310. The valve core 341 passes through a coil spring 343 disposed in a compressed state between a circular lower end portion and a peripheral portion of the central hole 331, and is constantly urged downward by the coil spring 343. As a result, the valve 342 maintains a closed state in contact with the valve seat formed of the open end 310a of the upper inner cylindrical wall 310. The valve 342 is formed from a soft elastic material such as silicone resin.

  The lid 300 is attached to the fitting protrusion 210 of the bottle body 200, and the male helix 211 located on the outer periphery of the fitting protrusion 210 and the female helix 311 located on the inner periphery of the outer peripheral wall 301 of the lid 300. And the lid 300 can be attached to the bottle main body 200. Between the lid 300 and the bottle main body 200, a circular flat plate-like packing 345 having a central hole penetrating the upper inner cylindrical wall portion 310 is disposed, so that the inside of the additive bottle 15 can be kept airtight. A concave gripping portion 230 is formed on the upper surface wall 201 of the bottle body 200.

  The addition bottle 15 and the lid 300 are made of a synthetic resin such as polyethylene resin or polypropylene resin, and a scale line indicating the remaining amount of the addition liquid 250 is attached to the outer surface of the addition bottle 15. The capacity | capacitance of the addition bottle 15 is 1.0-1.5L, Comprising: The scale line with the residual amount located in the lowest end is 100 ml is an exchange line. When the operator visually recognizes that the water level of the additive liquid 250 is located in the vicinity of the exchange line, the operator immediately replaces it with a new additive bottle 15 filled with the additive liquid 250.

  Referring to FIG. 2 again, the additive bottle 15 is accommodated in the bottle accommodating portion 14 so that it can be pulled out, and an insertion space 180 for an operator to insert a hand is formed above the additive bottle 15. . When the operator installs, replaces, or repairs the addition bottle 15, the operator inserts his / her hand into the insertion space 180 and hooks his / her finger on the gripping portion 230 of the addition bottle 15 exposed in the insertion space 180. It can be easily taken out by lifting it while pulling forward.

  Thus, in order for an operator to insert his / her hand into the insertion space 180 and easily pull out the additive bottle 15, the vertical dimension Y of the insertion space 180 is preferably 80 to 120 mm. Further, since the addition bottle 15 can be pulled out and taken out in an upright state without the operator bending forward, the separation distance in the vertical direction Y from the lower surface 5 of the apparatus main body 10 to the lower surface of the bottle housing portion 14 Is preferably 500 to 700 mm. In addition, when the operator takes out the addition bottle 15, the finger other than the thumb is hooked on the grip 230 and lifted with the thumb pressed against the front wall 203. The length dimension (dimension in the vertical direction Y) of the grip portion 230 is preferably 60 to 100 mm, and the width dimension (dimension in the front-rear direction Z) is preferably 20 to 40 mm.

  The bottle receiving portion 400 includes a flat portion 401, an outer peripheral wall portion 402 that stands up from the flat portion 401, a bottomed cylindrical liquid storage portion 403 that extends downward from an opening located at the center of the flat portion 401, and an outer peripheral wall portion. A hollow rectangular tube-shaped tube insertion portion 404 that protrudes outward from a part of 402 and extends downward. The tube insertion portion 404 is in communication with the liquid storage portion 403. Inside the lower end portion of the tube insertion portion 404, a cross-section ring-shaped fixing portion 405 into which the tip of the liquid feeding tube 220 is fitted is located. The liquid container 403 has a substantially conical protruding portion 407 protruding upward at the center portion of the bottom surface.

  The outer peripheral wall portion 402 and the liquid storage portion 403 of the bottle receiving portion 400 have shapes and sizes into which the lower end portion of the bottle main body 200 and the lid body 300 are fitted, respectively, and the outer peripheral wall portion 301 of the lid body 300. The bottle body 200 can be fixed to the bottle receiving part 400 by inserting the liquid into the liquid storage part 403. The bottle receiving portion 400 includes a notch 408 positioned at the lower end of the extending portion extending further outward in the width direction X from the tube insertion portion 404, and an extending portion positioned on the opposite side of the extending portion in the width direction X. And a notch (not shown) formed in the device is stably fixed to the apparatus main body 10 via screws.

  Referring to FIG. 22A, in the process of inserting the lid 300 of the addition bottle 15 into the bottle receiver 400, the lower inner cylindrical wall 320 of the lid 300 and the protruding portion 407 of the bottle receiver 400, Are separated in the vertical direction Y, the valve 342 of the lid 300 is in contact with the valve seat 310a and closed. In such a state, the additive 251 that has not been dissolved in water in the additive liquid 250 is precipitated and collected around the upper inner cylindrical wall portion 310 of the lid 300.

  Referring to FIG. 22B, the lower end of the valve core 341 in which the protruding portion 407 of the bottle receiving portion 400 is positioned inside the open end portion 320a of the lower inner cylindrical wall portion 320 by pushing the additive bottle 15 further downward. It abuts against the portion and moves it upward against the bias of the coil spring 343. When the valve core 341 moves upward, the valve 342 opens away from the valve seat 310a, and the additive liquid 250 in the additive bottle 15 passes through the plurality of water supply ports 332 and passes through the plurality of water supply ports 332. It flows into the liquid container 403. When the valve is opened, the valve 342 moves about 8 to 12 mm upward.

  As described above, when the check valve mechanism of the lid 300 is opened, a required amount of the additive liquid 250 is stored in the liquid storage section 403 of the bottle receiving section 400. The additive liquid 250 stored in the liquid storage unit 403 is sucked by the suction pump through the liquid feeding tube 220 and sent to the mixing tank in the apparatus main body 10. In such a case, when the additive 251 contained in the additive liquid 250 in the additive bottle 15 passes through the gap between the valve 342 and the valve seat 310a and moves from the water supply port 332 to the liquid storage unit 403, the liquid supply tube 220 is provided. May clog and may not be able to send a sufficient amount of water to the mixing tank.

  In the endoscope cleaning apparatus 10 according to the present embodiment, the additive 251 in the additive liquid 250 is precipitated around the upper inner cylindrical wall portion of the lid 300, and the upper inner cylindrical wall portion 310 serves as a barrier. Thus, the additive 251 is prevented from flowing into the liquid storage part 403 of the bottle receiving part 400 from the water supply port 332. Therefore, it can be said that the upper inner cylindrical wall portion 310 is an inflow barrier for suppressing the additive 251 precipitated on the lid 300 from flowing into the water supply port 332 and the liquid storage portion 403. In order for the upper inner cylindrical wall portion 310 to function as an inflow barrier for the additive 251, the height dimension H <b> 3 is preferably 5.0 mm or more.

  The width dimension W9 from the outer peripheral surface of the liquid container 403 to the protruding portion 407 is 20 to 30 mm, and the height dimension of the water level WL of the additive liquid 250 that has opened and flowed into the liquid container 403 of the bottle receiver 400 is shown. H4 is 20-30 mm. Moreover, the front-end | tip part 221 of the liquid feeding tube 220 fixed to the fixing | fixed part 405 of the tube insertion part 404 is spaced apart from the bottom face of a liquid storage part, The spacing dimension R5 is 3.0-8.0 mm. . Since the tip 221 of the liquid feeding tube 220 is separated from the bottom surface of the liquid storage unit 403, even if the additive 251 that has not been dissolved in the bottle body 200 flows into the liquid storage unit 403, the liquid storage unit Even if it precipitates on the bottom surface of 403, only the additive liquid 250 can be sucked without clogging the tip 221 with the additive 251.
