Is held in a state inclined with respect to the door 500 by a predetermined angle θb. As a result, when the door 500 is fully opened, the insertion portion 600 is inclined obliquely with respect to the vertical direction, and the opening formed above the insertion portion 600 faces obliquely upward. It has become.

Furthermore, in the storage unit 104 of the present embodiment, when the door 500 is fully opened, the arm unit 520 (guide unit 521) provided on the side plate 502 of the door 500 is replaced with the third plate unit 413 of the moving unit 400. It is in a state of being separated from the roller 460 provided in the. Thus, when the door 500 is completely opened, no external force is applied to the tension spring 470 provided between the moving unit 400 and the main body 300, and the tension spring 470 is in a contracted state. As a result, when the door 500 is fully opened, as shown in FIG. 6 and the like, the moving part 400 is pushed upward by the tension spring 470 and attached to the moving part 400. The connecting member 440 is also retracted upward.
In the state where the door 500 is fully opened, as shown in FIG. 6 and the like, the protrusion 620 provided on the rear wall 603 of the insertion portion 600 is connected to the guide portion 521 provided on the arm portion 520 of the door 500. They are in contact.

  Subsequently, the stock solution cartridge 20 is inserted into the insertion portion 600 with the door 500 fully open. In the storage unit 104 of the present embodiment, as described above, the insertion unit 600 is inclined toward the outside of the storage unit 104 when the door 500 is completely open. Furthermore, inclined surfaces are formed on the upper portions of the first side wall 601, the second side wall 602, and the front wall 604 of the insertion portion 600, and the opening of the insertion portion 600 is widened. Thereby, in the accommodating part 104 of this embodiment, compared with the case where this structure is not employ | adopted, it becomes easy to insert the stock solution cartridge 20 in the insertion part 600. FIG.

  Further, as described above, in a state where the door 500 is opened, the insertion portion 600 is held by being inclined toward the main body portion 300 by a predetermined angle θb with respect to the door 500, and separated from the door 500. It has become. Therefore, when the stock solution cartridge 20 is inserted into the insertion portion 600, the stock solution cartridge 20 is less likely to hit the door 500, and the stock solution cartridge 20 can be inserted more easily than when this configuration is not adopted.

  FIG. 9A shows the storage unit 104 after the stock solution cartridge 20 is inserted into the insertion unit 600 with the door 500 fully opened. As shown in FIG. 9A, when the stock solution cartridge 20 is inserted into the insertion portion 600, the stock solution cartridge 20 is held on the bottom plate surface 605, the front wall 604, etc. of the insertion portion 600, so that the storage portion 104 is inclined to the front side.

Subsequently, by pushing the front plate 501 of the door 500 toward the main body 300, the door 500 is rotated about the rotation shaft 560, and the door 500 is gradually closed.
In the storage portion 104 of the present embodiment, the insertion portion 600 maintains a predetermined angle θb with respect to the door 500 by the torsion spring 570, and the projection portion 620 is in contact with the guide portion 521 of the door 500. The door 500 is rotated and moved to the main body 300 side in conjunction with the closing of the door 500 to the main body 300 by the rotational movement.

As shown in FIG. 9B, when the angle with respect to the vertical direction of the door 500 becomes an angle θc (= θb) as an example of a predetermined first angle as a result of the rotational movement, the door The insertion part 600 that rotates and moves in conjunction with 500 comes along the vertical direction. That is, when the door 500 is at an angle θc with respect to the vertical direction, the opening of the insertion portion 600 faces upward in the vertical direction, and the bottom plate surface 605 of the insertion portion 600 is along the lower surface 305 of the main body portion 300. Become.
Thereby, the stock solution cartridge 20 inserted in the insertion part 600 will be in the state along the perpendicular direction. Further, the closing member 210 of the stock solution cartridge 20 faces upward and faces the connecting member 440 attached to the moving unit 400.

  Further, as shown in FIG. 9B, when the door 500 has an angle θc with respect to the vertical direction, the guide portion 521 provided on the side plate 502 (arm portion 520) of the door 500 is moved to the moving portion. It comes into contact with the surface of the roller 460 provided on the 400 third plate portion 413. Further, the protrusion 620 of the insertion portion 600 that has been in contact with the guide portion 521 is separated from the guide portion 521.

Subsequently, when the door 500 is further pushed toward the main body part 300 side, the arm part 520 extending from the door 500 is rotated about the rotation shaft 560 as the door 500 rotates, and is provided at the tip of the arm part 520. The guided portion 521 moves downward in the vertical direction while drawing an arc. As a result, the roller 460 that contacts the guide portion 521 is pushed downward, and the second rail member 352 provided in the moving portion 400 slides downward on the first rail member 351 provided in the main body portion 300. As a result, the entire moving unit 400 moves downward with respect to the main body unit 300.
That is, the rotational movement of the door 500 with the rotation shaft 560 as a fulcrum is caused by the guide portion 521, the roller 460, the rail 350 (the first rail member 351, the second rail member 352), and the like of the moving portion 400 along the vertical direction. Converted to linear motion.

  In the present embodiment, the roller 460 is rotatably attached to the third plate portion 413 of the moving unit 400. Therefore, when the roller 460 is pushed downward by the guide portion 521 of the door 500, the roller 460 rotates, and the guide portion 521 pushes the third plate portion 413 while moving on the rotating roller 460. It has become. Thereby, compared with the case where the roller 460 is not provided, a load due to friction or the like of the guide portion 521 is reduced, and the moving portion 400 can be moved smoothly when the door 500 is opened and closed.

In the present embodiment, as the moving part 400 moves downward, the connecting member 440 attached to the first plate part 411 of the moving part 400 also approaches the closing member 210 of the stock solution cartridge 20. Move down.
Moreover, in this embodiment, when the moving part 400 moves below, the lower end of the tension spring 470 attached to the lower part of the moving part 400 moves below, and the tension spring 470 extends below.

  Subsequently, the door 500 is further rotated and moved toward the main body 300, and the door 500 is completely closed with respect to the storage unit 104. FIG. 9C and FIG. 10B show the storage unit 104 when the door 500 is completely closed. As shown in FIGS. 9C and 10B, when the door 500 is completely closed, the latch claw 510 provided on the door 500 engages with the latch receiver 310 provided on the main body 300. The door 500 is locked with respect to the main body 300.

Further, the moving unit 400 moves downward in conjunction with the operation of rotating and completely closing the door 500, so that the door 500 is attached to the moving unit 400 as shown in FIGS. 9C and 10B. The connected connecting member 440 is pressed against the closing member 210 of the stock solution cartridge 20 to be connected.
When the door 500 is completely closed, the second projecting portion 220 of the closing member 210 (see FIG. 8C) is placed inside the cylindrical portion 441 of the connecting member 440 (see FIG. 8A). Enters and the inner peripheral surface of the cylindrical portion 441 is in close contact with the outer surface of the second protrusion 220.

Here, in the sterilizing water generator 100 of the present embodiment, the stock solution is supplied by the pump 22 (see FIG. 3). At this time, the close contact between the closing member 210 and the connecting member 440 is insufficient. In addition, air may enter from between the closing member 210 and the connecting member 440, and the pump 22 may not be able to suck the stock solution.
On the other hand, in the storage unit 104 of the present embodiment, as described above, the closing member 210 of the stock solution cartridge 20 faces the connecting member 440, that is, the position of the connecting member 440 relative to the closing member 210 is determined. Thus, the moving unit 400 is moved downward.
Thereby, compared with the case where this structure is not employ | adopted, the movement operation of the connection member 440 with respect to the closing member 210 is stabilized, and the adhesiveness of the connection member 440 and the closing member 210 improves.

  Furthermore, in this embodiment, a compression spring 430 is provided between the first plate portion 411 of the moving unit 400 and the attachment member 420. As shown in FIG. 10B, when the door 500 is completely closed, the compression spring 430 is in a contracted state, and the connecting member 440 is closed by the elastic force of the compression spring 430. It is pressed against. As a result, the connectivity between the connecting member 440 and the closing member 210 is improved as compared with the case where this configuration is not adopted.

Next, an operation for removing the stock solution cartridge 20 from the storage unit 104 will be described. When the stock solution cartridge 20 is taken out from the storage unit 104, the above-described operations for inserting the stock solution cartridge 20 into the storage unit 104 may be performed in the reverse order.
That is, first, the upper portion of the front plate 501 of the door 500 is lightly pushed toward the main body 300, so that the latch claw 510 is disengaged from the latch receiver 310 provided in the main body 300, and the door to the main body 300 is released. Unlock 500.

Here, as shown in FIG. 9C, when the door 500 is closed, the tension spring 570 is extended downward, and the torsion spring 570 is connected to the door 500. It is in the state which bent by being pushed by.
Therefore, when the lock of the door 500 with respect to the main body 300 is released, the extended tension spring 570 contracts to the original shape, so that the moving unit 400 moves upward. Then, the connection of the connecting member 440 to the closing member 210 of the stock solution cartridge 20 is released, and the connecting member 440 is retracted above the main body 300.

  Here, in general, the stock solution cartridge 20 is taken out from the storage unit 104 in many cases using all the stock solution (chemical solution) in the stock solution cartridge 20 and replacing the stock solution cartridge 20 with a new one. In this case, the stock solution cartridge 20 is empty and light in weight. As described above, in the present embodiment, the connecting member 440 is strongly pressed against the closing member 210 of the stock solution cartridge 20. Therefore, when the stock solution cartridge 20 is empty and light in weight, the stock solution cartridge remains in close contact with the connection member 440 when the connection member 440 moves upward of the main body 300 as the moving unit 400 moves. 20 may move upward.

  On the other hand, in the storage unit 104 of this embodiment, a pressing plate 320 that protrudes toward the door 500 is provided on the back surface 303 of the main body unit 300. As a result, even when the stock solution cartridge 20 is in close contact with the connecting member 440 and moves upward, the upper portion of the stock solution bottle 200 is pressed by the holding plate 320 so that the stock solution cartridge 20 is separated from the connecting member 440. ing. As a result, it is possible to suppress the stock solution cartridge 20 from being moved above the main body 300 along with the movement of the moving unit 400.

Further, when the moving part 400 moves upward, the arm part 520 (guide part 521) of the door 500 is pushed upward via the roller 460 provided on the third plate part 413 of the moving part 400. As a result, the door 500 is rotationally moved with the rotation shaft 560 as a fulcrum and is opened to a state inclined by the angle θc with respect to the vertical direction.
That is, by the guide portion 521, the roller 460, the rail 350 (the first rail member 351, the second rail member 352) and the like, the linear motion upward of the moving portion 400 is changed to the rotational motion of the door 500 with the rotation shaft 560 as a fulcrum. Converted.

  Furthermore, as the door 500 opens, the bent torsion spring 570 returns to its original shape. Thus, even when the door 500 is opened to the angle θc, the insertion portion 600 into which the stock solution cartridge 20 is inserted is maintained in the state along the vertical direction.

Subsequently, by pulling the upper part of the door 500 away from the main body 300, the door 500 is rotated and opened with the rotation shaft 560 as a fulcrum.
When the door 500 is rotated, the guide part 521 provided at the tip of the arm part 520 in the door 500 also moves upward in the vertical direction while drawing an arc. As a result, the guide portion 521 comes away from the roller 460 and comes into contact with the protrusion 620 provided on the insertion portion 600.

When the door 500 is further opened, the projection portion 620 is pushed by the guide portion 521 as the door 500 rotates, so that the insertion portion 600 rotates about the rotation shaft 560 as a fulcrum. In the present embodiment, the torsion spring 570 provided between the door 500 and the insertion portion 600 causes the door 500 and the insertion portion 600 to rotate while maintaining a predetermined angle θb.
Here, as described above, when the insertion unit 600 rotates in conjunction with the opening operation of the door 500, the moving unit 400 and the connecting member 440 provided in the moving unit 400 are retracted above the storage unit 104. It has become a state. Thereby, when rotating the insertion part 600, interference with the stock solution cartridge 20 and the connection member 440 is suppressed.

And in the state which opened the door 500 completely, as mentioned above, the door 500 can maintain the state inclined only by the predetermined angle (theta) a with respect to the perpendicular direction. When the door 500 is fully opened, the insertion portion 600 is inclined by θb with respect to the door 500 while the opening faces obliquely upward as shown in FIG. 9A and the like. .
Accordingly, the stock solution cartridge 20 can be taken out from the storage portion 104 while suppressing interference with the door 500 by pulling the stock solution cartridge 20 obliquely upward from the insertion portion 600 with the door 500 opened.

  In the present embodiment, the arm pressing unit 520, the guide unit 521, the roller 460, the tension spring 470, the rail 350 (the first rail member 351, the second rail member 352), and the like constitute a moving pressing mechanism. The arm 520, the guide 521, the torsion spring 570, and the like constitute a moving mechanism, and the arm 520, the guide 521, the roller 460, the tension spring 470, and the rail 350 (first rail member 351, second rail member 352). ) And the like constitute a pressing mechanism.

Here, in the storage unit 104 of the present embodiment, as described above, the damper 330 is provided between the main body unit 300 and the door 500. Thereby, when the door 500 is opened or closed with respect to the main body 300, the rotation speed of the door 500 can be adjusted. As a result, compared to a case where the present configuration is not adopted, for example, it is possible to suppress the generation of abnormal noise or the impact on the sterilizing water generator 100 caused by opening or closing the door 500 with force.
In this embodiment, a gear damper having a gear member 331 and a gear receiving member 332 is used as the damper 330. However, as long as the rotational speed of the door 500 can be adjusted, for example, a hydraulic damper or the like is used. The damper may be used.

  Further, in the storage unit 104 of the present embodiment, the stock solution cartridge 20 is in a state along the vertical direction when the angle of the door 500 becomes a predetermined angle θc with respect to the vertical direction. However, if the closing member 210 faces the connecting member 440, when the angle of the door 500 reaches a predetermined angle θc, the stock solution cartridge 20 is inclined by a predetermined angle from the vertical direction. It doesn't matter.

Furthermore, in the storage unit 104 of the present embodiment, the rail 350 is provided between the main body unit 300 and the moving unit 400 so that the moving unit 400 can be moved up and down with respect to the main body unit 300. The rail 350 is not necessarily provided as long as the moving unit 400 can move up and down with respect to the main body unit 300 in accordance with the opening / closing of the main body 300.
Furthermore, in this embodiment, the roller 460 is provided on the third plate part 413 of the moving part 400, and the guide part 521 provided on the arm part 520 of the door 500 moves smoothly on the roller 460. Even if a roller is provided not on the moving part 400 but on the arm part 520 side of the door 500, the same effect can be obtained.

Next, a method of detecting the connection of the connecting member 440 to the closing member 210 by the connection sensor 360 will be described with reference to FIGS.
The connection sensor 360 of the present embodiment is configured by a reflective photosensor in which a light emitting unit and a light receiving unit (not shown) are integrated. Then, the connection sensor 360 emits infrared light as signal light from the light emitting unit, and detects whether or not reflected light of the signal light is received by the light receiving unit. Specifically, in the connection sensor 360 of this embodiment, the connection member 440 is connected to the closing member 210 depending on whether or not the reflected light reflected by the light receiving unit 415 provided in the moving unit 400 is received. Detect whether or not.

As described above, the connection sensor 360 is attached to the first side surface 301 of the main body 300. Therefore, in the storage unit 104 of the present embodiment, the position of the connection sensor 360 does not change even when the door 500 is opened and closed.
On the other hand, the light receiving unit 415 that receives the signal light emitted from the connection sensor 360 is provided in the moving unit 400. Therefore, in the storage unit 104 of the present embodiment, the position of the light receiving unit 415 is also moved in the vertical direction as the moving unit 400 is moved in the vertical direction according to the opening / closing of the door 500.

  That is, as shown in FIGS. 10B and 9C, in the state where the door 500 is completely closed, as described above, the moving unit 400 moves downward, and the connecting member 440 moves the stock solution cartridge 20. The closing member 210 is connected. Furthermore, when the connecting member 440 is connected to the closing member 210 of the stock solution cartridge 20, the light receiving portion 415 provided in the moving portion 400 as the moving portion 400 moves downward. Has also moved downwards. Then, as shown in FIG. 10B, the light receiving portion 415 is in a state of facing the connection sensor 360 provided in the main body portion 300.

  Therefore, when the door 500 is completely closed and the connecting member 440 is connected to the closing member 210 of the stock solution cartridge 20, the signal light emitted from the connecting sensor 360 is reflected by the light receiving portion 415, The connection sensor 360 can receive the reflected light from the light receiving portion 415.

  On the other hand, as shown in FIGS. 10 (a) and 9 (b), in the state where the door 500 is opened so that the angle with respect to the vertical direction becomes a predetermined angle θc, as described above, The moving part 400 is retracted above the main body part 300 so that the connecting member 440 is separated from the closing member 210 of the stock solution cartridge 20. Furthermore, when the connecting member 440 is separated from the closing member 210 of the stock solution cartridge 20, the light receiving unit 415 provided in the moving unit 400 is retracted as the moving unit 400 is retracted above the storage unit 104. Is also moved above the storage unit 104.

  Further, although detailed illustration is omitted, as shown in FIG. 9A, even when the door 500 is opened such that the angle with respect to the vertical direction is larger than the angle θc, as shown in FIG. Similarly to the case shown, the light receiving unit 415 is moved above the storage unit 104 as the moving unit 400 moves.

  Therefore, when the door 500 is opened and the connecting member 440 is separated from the closing member 210 of the stock solution cartridge 20, the light receiving portion 415 is located above the connection sensor 360 and is connected to the light receiving portion 415. It does not face the sensor 360. As a result, when the connecting member 440 is away from the closing member 210, the signal light emitted from the connecting sensor 360 is not reflected by the light receiving unit 415, and the connecting sensor 360 reflects the reflected light from the light receiving unit 415. Cannot be received.

From the above, in the sterilizing water generation device 100 (housing unit 104) of the present embodiment, when the connection sensor 360 receives reflected light, the connection member 440 is connected to the closing member 210 of the stock solution cartridge 20. If the connection sensor 360 does not receive the reflected light, it can be determined that the connection member 440 is not connected to the closing member 210 (the connection member 440 is separated from the closing member 210).
In other words, in the sterilizing water generating apparatus 100 of the present embodiment, the connection sensor 360 is connected to the closing member 210 of the stock solution cartridge 20 by the connection sensor 360, and the connection member 440 is connected to the closing member 210 of the stock solution cartridge 20. It is possible to distinguish the separated state.

Here, as described above, in the storage unit 104 of the present embodiment, after the stock solution cartridge 20 inserted into the insertion unit 600 is moved to the main body unit 300, the connecting member 440 is moved to the closing member 210 side of the stock solution cartridge 20. Move and connect. Therefore, for example, whether or not the connecting member 440 is connected to the closing member 210 cannot be distinguished only by detecting the position of the stock solution cartridge 20 with a sensor.
On the other hand, in the sterilizing water generating apparatus 100 according to the present embodiment, by providing the connection sensor 360 and the light receiving portion 415 as described above, the connection state of the connection member 440 with respect to the closing member 210 can be distinguished. It is possible to suppress the occurrence of problems such as starting the supply of the stock solution even though the connecting member 440 is not connected to the member 210.

In the storage unit 104 of the present embodiment, even when the stock solution cartridge 20 is not inserted into the insertion unit 600, the moving unit 400 moves downward when the door 500 is completely closed. Become. As a result, the light receiving portion 415 provided in the moving portion 400 faces the connection sensor 360 provided in the main body portion 300, and the connection sensor 360 receives the reflected light reflected by the light receiving portion 415. It becomes like this. Therefore, in the sterilizing water generating apparatus 100 of the present embodiment, even when the stock solution cartridge 20 is not stored in the storage unit 104, it is determined that the closing member 210 and the connecting member 440 of the stock solution cartridge 20 are connected. Will do.
In such a case, the stock solution is sent from the stock solution cartridge 20 to the stock solution metering unit 23 for a certain period of time by a liquid level sensor 24 (see FIG. 3) that detects the level of the stock solution in the stock solution metering unit 23 (see FIG. 3). It can be determined that the stock solution cartridge 20 is not stored in the storage unit 104 (insertion unit 600).

  Further, in the present embodiment, for example, a photosensor in which a light emitting unit and a light receiving unit are integrated is used as the connection sensor 360. Also good. In this case, for example, by providing a light emitting part on the main body part 300 side and a light receiving part on the moving part 400 side, a connecting member for the closing member 210 is determined depending on whether or not the signal light from the light emitting part is received by the light receiving part. Whether or not 440 is connected can be distinguished.

  As described above, in the storage unit 104 of the present embodiment, the rotation operation of the door 500 can be converted into a linear motion, and the connecting member 440 is connected to the closing member 210 of the stock solution cartridge 20 by the linear motion. It is designed to be attached. Accordingly, the storage unit 104 according to the present embodiment has a connection error between the connecting member 440 and the closing member 210 as compared with a case where the connecting member 440 is attached to the closing member 210 while moving on the arcuate track, for example. And more reliable connection is possible.

  Furthermore, in the storage unit 104 of the present embodiment, according to the rotation operation of the door 500, the stock solution cartridge 20 is first set up in the vertical direction as the first step, and then the blocking member 210 of the stock solution cartridge 20 as the second step. The connecting member 440 is connected. Thereby, the connecting member 440 can be moved in a state where the position of the closing member 210 is fixed, and the moving operation of the connecting member 440 is stabilized. In addition, the adhesion between the connecting member 440 and the closing member 210 can be improved.
