In this case, the adjustment tool may be configured to include a first screw portion that protrudes along the central axis of the lid body, and the support tool may include a second screw portion that meshes with the screw portion. The lid main body is attached to the door by meshing the first screw portion with the second screw portion, and the lid main body is rotated together with the adjustment tool to cause the first screw portion and the second screw portion to rotate. By changing the amount of meshing with the screw portion, the position of the lid body with respect to the door changes. In this way, by rotating the lid body, the position of the lid body can be easily changed, and the pressure-bonding force of the lid portion when the door is closed can be increased.

  In the tabletop sterilizer according to this aspect, the position adjusting means can be switched between a locked state that restricts rotation of the lid body relative to the support and an unlocked state that allows rotation of the lid body relative to the support. It can be set as the structure provided with a locking mechanism. In this way, the position of the lid body can be adjusted by rotating the lid body with the locking mechanism in the unlocked state, and then the position of the lid body is fixed at the adjusted position by setting the locking mechanism to the locked state. Can do.

  In this case, the lock mechanism includes a plurality of adjustment holes arranged at a predetermined radial position from the central axis outside the first screw part, and a pin arranged to be detachable from one of the adjustment holes. It can be set as the structure provided with. In this way, the state of the lid body can be easily switched between the locked state and the unlocked state by the operation of inserting and removing the pins.

  Here, the pin is inserted into a lateral hole provided in the support via a coil spring, the pin is biased in the direction of the adjustment hole by the coil spring, and the tip of the pin is moved from the lateral hole. By projecting forward and pulling the tip of the pin against the bias of the coil spring, the pin is removed from the adjustment hole. If it carries out like this, the mechanism for insertion and removal of a pin can be simplified.

  Further, in this configuration, the lid support mechanism includes a support frame that supports the support on the door, and an opening capable of pulling the tip of the pin is provided at a position facing the pin of the support frame. It has been. If it carries out like this, insertion and removal of a pin can be smoothly performed through opening.

  In this configuration, it is desirable that a window for exposing the pin to the outside is provided in the door. If it carries out like this, a pin can be operated by opening a window and the position adjustment of a cover part can be performed more simply.

  As described above, according to the present invention, it is possible to provide a desktop sterilizer that can quickly cope with steam leakage even in an emergency.

The lid 200 is attached to the door 200, and when the door 200 is closed, the lid 401 closes the opening of the chamber 501. A water supply tank 600 and a drain tank 700 are detachably attached to the lower part of the main body 100. In this embodiment, water supply tank 600 and drainage tank 700 have the same shape, size, and structure.

  FIG. 3 is a view showing the external appearance of the desktop sterilizer 10 when the water supply tank 600 and the drain tank 700 are taken out.

  A tank storage unit 800 for mounting a water supply tank 600 and a drainage tank 700 is provided at the lower part of the main body 100. The tank storage unit 800 is a rectangular parallelepiped room with a front surface opened. The width of the tank storage unit 800 in the left-right direction is wider than the width in which the water supply tank 600 and the drainage tank 700 are arranged side by side. The vertical width of the tank storage unit 800 is slightly wider than the vertical width of the water supply tank 600 and the drainage tank 700. When the water supply tank 600 and the drainage tank 700 are stored in the tank storage unit 800 (see FIG. 2), the back surfaces of the water supply tank 600 and the drainage tank 700 are positioned slightly forward from the rear surface of the tank storage unit 800.

  When the water supply tank 600 and the drainage tank 700 are pulled forward from the state shown in FIG. 2 with a predetermined force, the water supply tank 600 and the drainage tank 700 are removed from the tank storage unit 800. In addition, the water supply tank 600 and the drain tank 700 are pushed into the tank storage unit 800 from the state shown in FIG. Thus, in the present embodiment, the water supply tank 600 and the drainage tank 700 are detachable from the tank storage unit 800.

  FIG. 4A is a front view showing the configuration of the tank storage unit 800.

  Referring to FIG. 4A, the tank storage unit 800 is equally divided into two left and right regions by a partition 801. The partition 801 is attached to the rear surface of the tank storage unit 800 and extends forward from the rear surface of the tank storage unit 800. The vertical width of the partition 801 is slightly narrower than the vertical width of the tank storage unit 800. The length of the partition 801 in the front-rear direction is shorter than the length of the tank storage unit 800 in the front-rear direction. The front end of the partition 801 is rounded in an arc shape in the left-right direction.

  The connector 101 to which the jack 626a (see FIG. 9A) of the water supply tank 600 is connected is exposed from the rear surface of the right region of the partition 801. A square-shaped hole 802 is formed on the rear surface of the right region of the partition 801, and a switch 901 (see FIG. 13A), which will be described later, is disposed at the back of the hole 802. Further, lock claws 102 a and 102 b protrude from the upper surface of the right region of the partition 801. These lock claws 102a and 102b can be elastically displaced upward. Further, the lock claws 102a and 102b are formed in a mountain shape convex downward when cut in the front-rear direction. Similarly to the right area, the connector 103, the two lock claws 104a and 104b, and the hole 803 are also arranged in the right area of the partition 801.

  The water supply tank 600 is attached to the area on the right side of the partition 801, and the drainage tank 700 is attached to the area on the left side of the partition 801. When the water supply tank 600 is pushed into the right area, the water supply tank 600 is guided by the partition 801 and advances in the right area in the depth direction. When the water supply tank 600 advances to a predetermined position, the lock claws 102 a and 102 b are pushed by the rear surface of the water supply tank 600 and elastically displaced upward and ride on the upper surface of the water supply tank 600. After that, when the water supply tank 600 is further pushed in and the water supply tank 600 reaches a predetermined storage position, the jack 626a (see FIG. 9A) of the water supply tank 600 is connected to the connector 101, and the rear surface of the water supply tank 600 is connected. The formed protrusion 615 (see FIG. 13A) enters the hole 802. At this time, the lock claws 102a and 102b are fitted into the recesses 625a and 625b (see FIG. 9A) on the upper surface of the water supply tank 600, and the water supply tank 600 is positioned at the storage position. Thus, the installation of the water supply tank 600 is completed.

  The drainage tank 700 is mounted in the same manner as described above. The drainage tank 700 is guided to the partition 801 by being pushed into the left region of the partition 801 and is mounted at the storage position of the left region of the tank storage unit 800. When the drainage tank 700 is positioned at the storage position, the jack 726a (see FIG. 9B) of the drainage tank 700 is connected to the connector 103, and a protrusion (not shown) formed on the rear surface of the drainage tank 700 has a hole 803.

  FIG. 11 is a diagram illustrating the appearance of the lid 620. FIG. 11 shows a state in which the lid 620 is inverted in the vertical direction.

  A filter 623 is attached to the lid 620 at positions corresponding to the two openings 621 and 622 (see FIG. 9A). The filter 623 is for preventing dust from entering the water tank 611. A pipe-shaped base 626b is formed at the center of the rear portion of the lid 620, and a jack 626a is integrally formed with the base 626b. The internal space of the jack 626a is connected to the internal space of the base 626b. The jack 626a and the base 626b are integrally formed with the lid 620. A pipe 626c is attached to the upper part of the base 626b. A filter for filtering water is mounted inside the pipe 626c.

  Further, a resinous shaft 627b extending vertically is mounted on the rear portion of the lid 620 by a resinous attachment 627a. A float 627c floating on water is supported on the shaft 627b so as to be movable up and down. A ring-shaped magnetic body is included inside the float 627c so as to surround the shaft 627b. An O-ring 627d that prevents the float 627c from coming off is attached to the tip of the shaft 627b.

  In plan view, the lid 620 has the same contour as the tank body 610. A series of grooves 628 into which the upper edge of the tank body 610 is fitted are formed on the periphery of the lid 620. The gap of the groove 628 is slightly narrower than the thickness of the upper edge of the tank body 610. The lid 620 is attached to the tank main body 610 by fitting the upper edge of the tank main body 610 into the groove 628 while expanding the groove 628.

  FIG. 12 is a view showing the appearance of the water supply tank 600 with the lid 620 attached to the tank body 610, FIG. 13A is a cross-sectional view taken along the line AA ′ in FIG. 12, and FIG. It is BB 'sectional drawing of.

  Referring to FIG. 13A, the tank body 610 has a recess 614 formed on the lower surface of the protrusion 613. Further, the tank main body 610 is integrally formed with a protrusion 615 protruding rearward at a position shifted to the left side from the jack 626a.

  When the water supply tank 600 is positioned at the storage position as shown in FIG. 2, the lock claws 102a and 102b (see FIG. 4A) are fitted into the recesses 625a and 625b as described above, and the water supply tank 600 is locked. . The jack 626a is connected to the connector 101 on the main body 100 side, and the protrusion 615 pushes the switch 901 on the main body 100 side. The connector 101 is connected to a fluid circuit arranged in the main body 100, and the switch 901 is connected to a circuit board in the circuit box 900 (see FIG. 5) by wiring. When the protrusion 615 pushes the switch 901, it is detected that the water supply tank 600 is attached.

  As shown in FIG. 13A, the lower end of the pipe 626 c is positioned near the bottom surface of the water tank 611. For this reason, almost all water can be sucked from the water tank 611 by applying a negative pressure to the connector 101.

Sometimes, magnetic sensors 902a and 902b are arranged at positions facing the float 627c in the front-rear direction, respectively. When the water supply tank 600 is in a drought state, the float 627c is at the position of the solid line (the lowest position) in FIG. 13B, and when the water supply tank 600 is in a full state, the float 627c is a broken line in FIG. It is in the position (top position). Accordingly, when the water supply tank 600 is in a drought state, the magnetic sensor 902a detects the float 627c, and when the water supply tank 600 is in a full water state, the magnetic sensor 902b detects the float 627c.

  The magnetic sensors 902a and 902b are connected to a circuit board in the circuit box 900 by wiring. The control unit disposed on the circuit board determines the amount of water in the water supply tank 600 based on the outputs of the magnetic sensors 902a and 902b, and appropriately displays the determination result on the monitor 302 (see FIG. 1). For example, when the water supply tank 600 is in a drought state, the control unit causes the monitor 302 to display a notification indicating that fact. Further, the control unit may output this notification by voice. Further, the control unit stops the sterilization operation when the water supply tank 600 is in a drought state.

  In addition, although the structure of each part was demonstrated about the water supply tank 600 here, the structure similar to FIG. 13 (a), (b) is distribute | arranged also to the drainage tank 700 side.

  14A and 14B are cross-sectional views when the drain tank 700 is cut at the same position (A-A 'position, B-B' position) as FIG. As shown in FIGS. 14A and 14B, a switch 903 and magnetic sensors 904a and 904b are disposed on the main body 100 side, and a protrusion 715, a shaft 727b, and a float 727c are disposed on the drainage tank 700. ing. With these configurations, it is determined that the drainage tank 700 is attached to the tank storage unit 800 and whether the drainage tank 700 is full or drought. When the drain tank 700 is determined to be full, a notification indicating that is displayed on the monitor 302 and the sterilization operation in the desktop sterilizer 10 is stopped. The drainage tank 700 is also provided with a protrusion 713 and a recess 714. Therefore, the drainage tank 700 can be easily pulled out by placing a finger on the recess 714.

  FIG. 15 is a diagram schematically showing the flow of steam in the tabletop sterilizer 10.

  As shown in FIG. 15, a band heater 502 is installed in the chamber 501. Further, the temperature and pressure in the chamber 501 are detected by the temperature sensor 506 and the pressure sensor 507.

  During the sterilization operation, first, a vacuuming operation is performed on the chamber 501. In the evacuation operation, the band heater 502 is activated, and water (purified water) in the water supply tank 600 is stored in the steam generator 503. Thereafter, the vacuum pump 505 is differentiated, and the air in the chamber 501 is caused to flow to the drain tank 700 via the radiator 504. In this way, a predetermined amount of steam is supplied from the steam generator 503 into the chamber 501 in a state where the inside of the chamber 501 is at a negative pressure. The above operation is repeated a predetermined number of times. Thereby, the inside of the chamber 501 is brought into a state close to a vacuum.

  After the vacuuming operation is performed in this way, the sterilization operation is started. In the sterilization operation, steam is supplied from the steam generator 503 into the chamber 501. A medical instrument or the like housed in the chamber 501 is sterilized by this steam. Thereafter, when the temperature and pressure in the chamber 501 decrease, the vacuum pump 505 is activated, and the inside of the chamber 501 is brought close to vacuum. Thereafter, steam is again supplied from the steam generator 503 into the chamber 501. The above operation is repeated a predetermined number of times. Thereby, the medical instrument etc. which were accommodated in the chamber 501 are sterilized.

  When the sterilization operation is completed, a steam removal operation is performed. In the vapor removal operation, the chamber 501 is opened to the atmosphere, and the vacuum pump 505 is activated. As a result, the steam in the chamber 501 is sent to the drain tank 700 via the radiator 504. Further, the operation of the band heater 502 is stopped.

  During the evacuation operation, the sterilization operation, and the vapor removal operation, the vapor in the chamber 501 is liquefied by the radiator 504 and sent to the drain tank 700. Thereby, water accumulates in the drain tank 700. Further, the water in the water supply tank 600 is consumed during the evacuation operation and the sterilization operation. When the drainage tank 700 is full, the drainage tank 700 is taken out from the tank storage unit 800 and the drainage tank 700 is drained. Further, when the water supply tank 600 is in a drought state, the water supply tank 600 is taken out from the tank storage unit 800 and water supply to the water supply tank 600 is performed. The drainage tank 700 after drainage and the water supply tank 600 after water absorption are remounted in the tank storage unit 800.

  Next, a lid support mechanism 400 that supports the lid 401 will be described with reference to FIGS.

  16 is an exploded perspective view of the lid support mechanism 400, and FIG. 17 is a perspective view of the main part of the lid support mechanism.

  Referring to FIG. 16, the lid support mechanism 400 includes an adjustment tool 402, a pin 403, a coil spring 404, a support tool 405, an O-ring 406, a support column 407, spacers 408 and 409, a support frame 410, Screws 411 and 413 and washers 412 and 414 are provided. The lid 401 is configured by mounting a ring-shaped packing 401b around a disc-shaped lid main body 401a. In the center of the lid main body 401a, a hole 401c is provided that penetrates along the central axis L0.

  Referring to FIG. 17, the adjustment tool 402 has a configuration in which cylindrical screw portions 402 a and 402 b are formed on the front and rear sides of a disk-shaped main body. The centers of the disk-shaped main body and the cylindrical screw portions 402a and 402b coincide with the central axis L0. A plurality of adjustment holes 402c are formed at predetermined radial positions from the central axis L0 outside the screw portion 402b. The pin 403 has a small-diameter portion 403a, and a groove 403b is formed over the entire circumference near the tip of the small-diameter portion 403a. The coil spring 404 is wound with a diameter larger than the small diameter portion 403a and smaller than the main body of the pin 403.

  The support 405 has a shape in which a part of the upper and lower portions of the columnar shape is cut out in a planar shape. The support tool 405 is formed with screw holes 405a penetrating in the front-rear direction and vertical holes 405b and 405c penetrating vertically. Further, a lateral hole 405d penetrating in the front-rear direction is formed in the support 405 next to the screw hole 405a.

  The screw hole 405 a has a diameter that meshes with the screw portion 402 b of the adjustment tool 402. The diameters of the vertical holes 405b and 405c are slightly larger than the diameters of the support columns 407 and smaller than the diameters of the spacers 408 and 409. The inner diameters of the spacers 408 and 409 are slightly larger than the outer shape of the support column 407. The support column 407 has a pipe shape, and screws are formed on the upper and lower inner peripheral portions. The diameter of the lateral hole 405d changes stepwise inside. The diameter of the lateral hole 405d is smaller than the diameter closer to the pin 403 than the diameter closer to the pin 403. The diameter of the side hole 405d closer to the pin 403 is slightly larger than the main body of the pin 403, and the diameter of the side hole 405d far from the pin 403 is slightly larger than the small diameter part 403a of the pin 403.

  At the time of assembly, first, the pin 403 and the coil spring 404 are passed through the lateral hole 405d in a state where the small diameter portion 403a of the pin 403 is passed through the coil spring 404. At this time, the pin 403 is pushed in while compressing the coil spring 404 until the tip of the small diameter portion 403a protrudes from the lateral hole 405d. In this state, the O-ring 406 is fitted into the groove 403b at the tip of the pin 403, and the pin 403 is prevented from coming off.

  Next, the support column 407 is passed through the vertical holes 405 b and 405 c of the support tool 405. At this time, the support column 407 protrudes from the top and bottom of the support 405 by the same height as the spacers 408 and 409. In this state, spacers 408 and 409 are fitted on the upper and lower portions of the support column 407, respectively.

  The assembly thus assembled is mounted on the support frame 410 of FIG. The plate portions 410a and 410b of the support frame 410a are formed with holes 410c (one hole is not shown) penetrating vertically in the center position. The interval between the plate portions 410 a and 410 b is slightly wider than the length of the support column 407. When the structure is mounted on the support frame 410, the support column 407 is inserted between the plate portions 410a and 410b, and the upper and lower positions of the support column 407 are aligned with the holes 410c of the plate portions 410a and 410b. In this state, the screws 411 and 413 are fastened to the upper and lower sides of the support column 407 via the washers 412 and 414. Thus, the support tool 405 is attached to the support frame 410 so as to be rotatable around the support column 407.

  In the support frame 410, a circular opening 410d is formed at a position facing the horizontal hole 405d of the support tool 405. Therefore, when the support tool 405 is attached to the support frame 410 as described above, the tip of the pin 403 is exposed from the opening 410d. The operator can pinch the pin 403 by pinching the tip of the pin 403 with a predetermined instrument through the opening 410d.

  Next, the adjustment tool 402 is attached to the lid 401. The screw portion 402a of the adjustment tool 402 is passed through the hole 401c of the lid main body 401a, and a nut is fitted to the screw portion 402a from the opposite side of the lid main body 401a. Thus, the adjustment tool 402 is attached to the lid 401. In this state, the screw portion 402 b of the adjustment tool 402 is engaged with the screw hole 405 a of the support tool 405. When the lid part 401 is rotated in the circumferential direction, the meshing amount of the screw part 402b of the adjustment tool 402 and the screw hole 405a of the support tool 405 changes, and accordingly, the lid part 401 moves in the front-rear direction (thickness direction of the door 200). It is displaced to. At this time, the pin 403 is pulled by holding the front end of the pin 403 so that the pin 403 does not hinder the rotation of the adjustment tool 402. Thus, when the front-rear position of the lid 401 is set to a predetermined position, the pin 403 is released and the pin 403 is inserted into any of the adjustment holes 402 c of the adjustment tool 402. Thereby, the attachment of the lid 401 to the support frame 410 is completed.

  FIG. 18 is a diagram illustrating a state where the lid 401 is attached to the support frame 410. In this state, the lid 401 can be rotated in the left-right direction within a predetermined angle range. The tip of the pin 403 is exposed from the opening 410d. As shown in FIG. 2, the support frame 410 is attached to the door 200 such that the lid 401 is disposed inside the door 200.

  19 and 20 are cross-sectional views taken along the line C-C 'of FIG.

  As shown in FIG. 19, in a normal state, the pin 403 fits into the adjustment hole 402c, and thereby the rotation of the lid 401 is restricted. When the lid 401 is displaced in the front-rear direction, the tip of the pin 403 is picked and the pin 403 is pulled forward, and the pin 403 is retracted from the adjustment hole 402c. As a result, the state shown in FIG. 20 is obtained. In this state, when the lid portion 401 is rotated in the circumferential direction, the meshing amount of the screw portion 402b of the adjustment tool 402 and the screw hole 405a of the support tool 405 changes, and accordingly, the lid portion 401 is moved in the front-rear direction (door 200). In the thickness direction). When the pin 403 is released at a desired displacement position, the pin 403 is fitted into the adjustment hole 402c again, and the rotation of the lid 401 is restricted.

  FIG. 21 is a front view of the structure with the cover 202 removed from the state of FIG.

  The position adjustment of the lid 401 is performed with the cover 202 removed from the door 200 as shown in FIG. In this state, the pin 403 is pulled through the opening 410d and the internal lid 401 is rotated, so that the position of the lid 401 is adjusted. As shown in FIG. 21, when the cover 202 is removed, the door lock portion 203 and the panels 204 and 205 are exposed together with the support frame 410. The front side of the lid 401 is covered with panels 204 and 205.

<Effect of embodiment>
As described above, according to the present embodiment, the following effects are exhibited.

  By displacing the lid 401 toward the chamber 501, the crimping force of the lid 401 when the door 200 is closed is increased. Therefore, when a steam leak occurs, the steam leak can be eliminated by adjusting the position of the lid 401. In this way, even in an emergency, it is possible to quickly respond to steam leakage on site.

  By rotating the lid main body 401a together with the adjustment tool 402 and changing the amount of engagement between the screw portion 402b and the screw hole 405a, the position of the lid main body 401a with respect to the door 200 can be changed. Thus, by rotating the lid body 401a, the position of the lid body 401a can be easily changed, and the pressure-bonding force of the lid portion 401 when the door 200 is closed can be increased.

  The position of the lid body 401a can be adjusted by retracting the pin 403 from the adjustment hole 402c and turning the lid body 401a with the lid 401 in the unlocked state, and then fitting the pin 403 into the adjustment hole 402c. Thus, by setting the lid 401 to the locked state, the position of the lid main body 401a can be fixed to the adjusted position.

  In this case, the state of the lid body 401a can be easily switched between the locked state and the unlocked state by the operation of inserting and removing the pin 403 with respect to the adjustment hole 402c.

  Further, by pulling the tip of the pin 403 against the bias of the coil spring 404, the pin 403 is pulled out of the adjustment hole 402c. If comprised in this way, the mechanism for insertion / extraction of the pin 403 can be simplified.

  In addition, an opening 410 d capable of pulling the tip of the pin 403 is provided at a position facing the pin 403 of the support frame 410. For this reason, the pin 403 can be smoothly inserted and removed through the opening 410d.

<Example of change>
In the above embodiment, the cover 202 has to be removed when the pin 403 is operated. On the other hand, for example, as shown in FIG. 22, a window 206 may be provided at a position facing the pin 403 of the cover 202, and when the window 206 is opened, the tip of the pin 403 may be exposed to the outside. In the configuration of FIG. 22, a plate-like shielding member 206a is slidably attached to the cover 202, and the window 206 is closed by the shielding member 206a. A knob 206b is integrally formed at the lower end of the shielding member 206a. When the shielding member 206a is slid upward with the knob 206b, the window 206 is opened and the tip of the pin 403 is exposed to the outside.

  In this configuration, since it is not necessary to remove the cover 202 when adjusting the position of the lid 401, the adjustment work of the lid 401 can be performed more easily.

  Further, the adjustment tool 402 does not necessarily have to be directly attached to the lid main body 401a, and may be attached to the lid portion 401 via another member. The attachment method of the adjustment tool 402 with respect to the cover part 401 is not restricted to the method shown by the said embodiment.

  In addition, the lock mechanism for restricting the rotation of the lid 401 is not limited to the configuration using the fitting between the pin 403 and the adjustment hole 402c as in the above embodiment, and may be met by other configurations. .

  In addition, the embodiment of the present invention can be variously modified as appropriate within the scope of the technical idea shown in the claims.
