Below, according to Fig. 1 to Fig. 8 and structure shown in Figure 9, the control work of this embodiment 2 is described.Unlatching (ON) operation by power switch button 26 becomes the state (power connection state) that the power supply of steam autoclave 1 is added.Under this state, lock-up solenoid valve device 20 is cold state.Therefore, the state of lock pin 21 for utilizing helical spring to stretch out, and be in the entopic state that jam plate portion 16 can not be inserted into insertion section 18.Bleeding portion 34 is for having closed the state of the air bleeding valve of inner chamber 4 by the dextrad rotation.
Under this state, shown in the double dot dash line among Fig. 3, thereby with support 7 serve as axle will cover 5 in breaking away from inner chamber 4 above the position of opening 3 move and in inner chamber 4, take in by the thing of sterilizing.Then, make arm 9 rotations be in the top position of the top opening 3 in the inner chamber 4, and the free end of arm 9 is embedded in the compressed part 8 so that cover 5.Compressed part 8 is the structure of open wide admitting mouthful 8B to a direction, and the rotation by arm 9 makes the free end of arm 9 invade from this admittances mouthful 8B, and is maintained at and is arranged on the position of the 8C of the portion that stops collision of the end of this admittances mouth 8B.Under this state, lid 5 be in top opening 3 in the inner chamber 4 directly over the position.
Under this state, by handle 10 is rotated in the forward Handle axis 13 is rotated in the forward, Handle axis 13 moves down (moving down) with respect to arm 9, covers 5 and moves down thereby make.Because moving down of lid 5, top opening 3 butts of annular seal ring 6 and inner chamber 4 also are compressed, thereby opening 3 is sealed above making.By handle 10 being rotated in the forward from this state because the relation of the female thread portion 12 that screws togather with pin thread 11 is moved (moving up) on the free end of arm 9, and should on move the top 8A restriction of (moving up) compacted 8.By handle 10 being rotated in the forward from this state, be under the bearing state of benchmark with arm 9, further compress annular seal ring 6, and cover 5 and move down (moving down) with Handle axis 13, thereby become the further compressive state of annular seal ring 6, make to be in airtight conditions in the inner chamber 4.Owing in the top of compressed part 8, be provided with first sense switch 15, when moving (moving up) on the free end of arm 9 and during, first sense switch, 15 actions (switch open (ON) this moment) with the top 8A butt of compressed part 8.
By these first sense switch, 15 actions (switch open (ON) this moment), and lock-up solenoid valve device 20 is energized by the control part (not shown) that is arranged in the control chamber 2A, lock pin 21 overcomes helical spring 25 and draws in to the attraction position, thereby becomes the inserted state that jam plate portion 16 can be inserted into insertion section 18.In addition, also can constitute, on the opportunity that is energized as lock-up solenoid valve device 20, by unlatching (ON) operation of power switch button 26, under the state (power connection state) that the power supply of steam autoclave 1 is added, lock-up solenoid valve device 20 is energized.
In this way, closing cap 5 makes in the inner chamber 4 and is in airtight conditions, becomes at lock-up solenoid valve device 20 under the state of "on" position, and jam plate portion 16 is inserted into insertion section 18.Be inserted in jam plate portion 16 under the entopic state of insertion section 18, as Fig. 1 and shown in Figure 3, chain 17 prolongs with the state of slightly elongation, so that the pars intermedia of chain 17 crosses the side of handle 10, thereby becomes state across the central part of jam plate portion 16 and handle 10.Be inserted under the entopic state of insertion section 18 second sense switch, 19 actions (switch open (ON) this moment) in this way in jam plate portion 16.In addition, be provided for keeping jam plate portion 16 to be inserted into the maintaining body of the state of insertion section 18 in this way, then can stablize the jam plate portion 16 that keeps being inserted into insertion section 18.That is,, also temporary fastening device can be set, jam plate portion 16 is inserted to insertion section 18 in mode with some resistances, and can extract when extracting when desiring to overcome this resistance as maintaining body.
As mentioned above, detect the entopic state that jam plate portion 16 is inserted into insertion section 18 by second sense switch 19, make lock-up solenoid valve device 20 become the no power state by described control part (not shown), utilize helical spring 25 as mentioned above and lock pin 21 is stretched out, the lock pin 21 that stretches out is invaded the stop hole 16A that is formed in the jam plate portion 16, thereby what become jam plate portion 16 extracts blocked state (prevention position), and because the lock pin 21 that stretches out makes the 3rd sense switch 24 actions (switch open (ON) this moment).As mentioned above, action by first sense switch 15, second sense switch 19 and the 3rd sense switch 24 (switch open (ON) this moment), by described control part (not shown) but make steam autoclave 1 become the initial state (the beginning holding state of sterilizing works) of sterilizing works.
In addition, when first sense switch 15, second sense switch 19, the 3rd sense switch 24 during according to the sequentially-operating of first sense switch 15, second sense switch 19, the 3rd sense switch 24, utilize described control part (not shown) but and control becomes the sterilizing works initial state, when not according to this order, if utilize described control part (not shown) but and be controlled to be and do not become the sterilizing works initial state, also can finish the normal running of steam autoclave 1.In this case, but when not becoming to the sterilizing works initial state, if utilize emergency warning lamp to light or the warning devices of buzzer startup etc. by described control part (not shown), but warning is not in the sterilizing works initial state, then user can be noticed this situation, and by (ON) opened in described power switch button 26 temporary closes (OFF) afterwards once more, thereby operate again from beginning at first.
But under the initial state (the beginning holding state of sterilizing works) of above-mentioned sterilizing works, set sterilising temp and sterilization time as sterilising conditions.Being set at of this sterilising temp opened (ON) temperature setting switch button 28, the temperature setting of then observing display part 32 and stipulating by make progress shift knob 30 and downward shift knob 31.In addition, (ON) time setting switch button 29 is opened in being set at of sterilization time, then observes display part 32 and carries out the official hour setting by make progress shift knob 30 and downward shift knob 31.In this setting operation,, can reset by opening (ON) reset switch button 27.
In this way, after the setting of sterilising conditions finishes, by pressing the start button 23 that (unlatching) is arranged at control chamber 2A, make the starting switch action (switch open (ON) this moment) in the corresponding with it control chamber 2A, order the beginning of sterilizing works, and begin sterilizing works by described control part (not shown).
As mentioned above, if the lock pin that stretches out 21 is invaded the stop hole 16A that is formed in the jam plate portion 16, thereby become the blocked state of extracting of jam plate portion 16, then chain 17 prolongs so that the pars intermedia of chain 17 crosses the side of handle 10 with the state of slightly elongation as mentioned above, thereby keeps the state across the central part of jam plate portion 16 and handle 10.Therefore, shown in the double dot dash line among Fig. 3,, then, make the situation that handle 10 is rotated to more than it be stoped by chain 17 because chain 17 cards end in the side of handle 10 if want to make handle 10 to cover 5 direction rotation to opening.The rotation of some handles 10 of Chan Shenging in this case, promptly, chain 17 card ends till the side of handle 10 is prevented to the rotation of handle 10, become some directions of loosening the compressive state of annular seal ring 6, even but under this state, because annular seal ring 6 remains on the compressive state with top opening 3 butts of inner chamber 4, thereby can not damage airtight in the inner chamber 4 thus.Even this be by the pitch of setting pin thread 11 and female thread portion 12 make with handle 10 rotations for example 180 degree can not bring influence to the sealing of annular seal ring 6 yet, thereby reach.Chain 17 is set to the length that can reach this function.
Because the beginning of sterilizing works makes the water of ormal weight automatically be injected in the inner chamber 4 by described control part (not shown).In addition, also can adopt water with ormal weight to be stored in structure in the inner chamber 4 in advance.And, because the beginning of this sterilizing works, the heater (not shown) that is arranged on inner chamber 4 inner bottom parts is energized, make the water heating evaporation in the inner chamber 4, and sterilizing works is carried out by control part (not shown), after the operation of regulations such as the sterilization process of implementing regulation, the deairing step in the inner chamber 4, finish sterilizing works.
Steam autoclave 1 has the pressure detecting portion (being also referred to as pressure transducer) 22 that is used to detect the pressure in the inner chamber 4.One of purpose of this structure is to make the situation that is in safe pressure reduction state in the inner chamber 4 in order to detect by the deairing step in the inner chamber 4.Because the end of sterilizing works, the pressure in the inner chamber 4 are reduced to setting following (pressure is zero).Pressure detecting portion 22 detects this pressure that has reduced, and detect the situation that inner chamber 4 interior temperature are reduced to setting following (for example below 60～80 ℃) by temperature sensor (not shown), make lock-up solenoid valve device 20 become "on" position by described control part (not shown).Pressure in the end owing to sterilizing works makes inner chamber 4 is reduced under the state below the setting, can occur the demonstration of the end of notice sterilizing works on display part 32.This is shown as, and is presented on the display part 32 with the written form of for example " end of sterilizing works ".And this moment, inner chamber 4 interior pressure can carry out safety verification by the demonstration of observing piezometer 33.
By this way, by the energising of lock-up solenoid valve device 20, lock pin 21 is attracted and the stop hole 16A from be formed at jam plate portion 16 returns, thereby makes the blocked state of extracting of jam plate portion 16 be disengaged.Therefore, by jam plate portion 16 18 is extracted from the insertion section, make the rotation stopping of 17 pairs of handles 10 of chain be disengaged, thereby handle 10 freely can be rotated.Meanwhile, the 3rd sense switch 24 actions (this moment, switch cut out (OFF)), and this signal is input to described control part (not shown).So, reverse rotation by this handle 10, and since with above-mentioned opposite effect, the lid 5 be moved upward and above inner chamber 4 opening 3 leave, simultaneously, the free end of arm 9 moves down (moving down) and leaves from the top 8A of compressed part 8, first sense switch, 15 actions (this moment, switch cut out (OFF)), and this signal is input to described control part (not shown).
By above-mentioned mode, confirmed to cover 5 be moved upward and opening 3 leaves above inner chamber 4 state under, by arm 9 is rotated to the direction of leaving from compressed part 8, shown in the double dot dash line among Fig. 3, can make and cover 5, thereby carry out the taking-up of the thing of being sterilized in the inner chamber 4 to the position rotation that opening 3 above inner chamber 4 leaves.
As mentioned above, in embodiment 2, by detect power connection by first sense switch 15 along with steam autoclave 1, the superior displacement of the arm 9 of perhaps closing opening 3 with lid 5 and producing is put, lock-up solenoid valve device 20 is energized, and become the entopic state that inserts that jam plate portion 16 can be inserted into insertion section 18, detect jam plate portion 16 to entopic insertion by second sense switch 19, lock-up solenoid valve device 20 becomes no power, stop the position to be stretched out by lock pin 21 to extracting of jam plate portion 16, handle 10 only is prevented from the side of handle 10 because of chain 17 cards to opening the rotation of covering 5 directions, and, because lock pin 21 stretching out in stop hole 16A makes the 3rd sense switch 24 start, thereby but the sterilizing works initial state become, when the pressure when detected the inner chamber 4 that finishes to cause owing to sterilizing works by pressure detecting portion in reduces, be energized by lock-up solenoid valve device 20, lock pin 21 is return, thereby removes the prevention of extracting to jam plate portion 16.
As mentioned above, in embodiment 1 and embodiment 2, after sterilizing works begins, in the sterilizing works certainly much less, as long as under the state that the pressure of intracavity has risen in being in, owing to can keep by chain 17 and can not open the state of lid by the operation of handle, thereby the danger that can avoid the outflow owing to steam to cause.So, if it (is zero air pressure among the embodiment that the pressure in the inner chamber 4 is reduced to setting following ... atmospheric pressure), then owing to can open by the rotation of handle 10 and cover 5, thereby when the pressure in the inner chamber 4 is higher, can avoid because of covering 5 danger that outflow caused that are opened the steam that produces.In addition, for in use steam autoclave, by appending the holding device of closing of lid 5 of the present invention, the safety of existing steam autoclave is improved, thereby can not purchase on a barter basis existing steam autoclave and continuation use safely, and can bring into play the effect of reduction of expenditure fully.
In the foregoing description 1 and 2, the Security Countermeasures when waiting the power supply that causes steam autoclave 1 to disconnect have been told about because of having a power failure.That is, because steam autoclave 1 pressure in the inner chamber 4 in sterilizing works is higher, therefore when the power supply of steam autoclave 1 under this state was disconnected, being opened then as operculum 5 this moment, inner chamber 4 interior steam can spray and very danger.Therefore, when the power supply of steam autoclave 1 was disconnected, lock-up solenoid valve device 20 becomes closed (OFF) (no power), maintains the blocked state of extracting of jam plate portion 16 by making lock pin 21, can avoid this danger.
In addition, though in the foregoing description 1 and 2, thereby adopted chain 17 cards to end the structure that stops the rotation of handle 10 in the side of handle 10, but substituted the structure of this mode, thereby also can adopt chain 17 cards to end the structure that stops the rotation of handle 10 at handle 10.For example, when handle 10 is made of with being used to the decorative panel of Handle axis 13 is installed the operating portion that forms rectangular ring as shown in the figure, owing to there is the hollow bulb 10P be formed between this decorative panel 10S and other limit C or the D, so also can adopts chain 17 to pass this hollow bulb 10P and jam plate portion 16 is inserted into the mode of insertion section 18.At this moment, chain 17 cards end the circumference at hollow bulb 10P, thereby stop the rotation of handle 10.
Because the central part of handle 10 is installed on the Handle axis 13, therefore the shape of handle 10 also can adopt central part be installed on the Handle axis 13 other shape (for example, square ring-type handle, rod or tabular handle from central part edge exhibition to the left and right, be radial handle from central part along the spread shape, the star shape handle, oval handle, perhaps as vehicle steering like this with from central part to radial direction along the round handle of the transverse arm supporting of exhibition etc.), no matter adopt which kind of shape, as long as for chain 17 card ends lateral part or medial part at handle 10, thereby the structure that the rotation of handle 10 is prevented from gets final product.Therefore, only need the profile of handle 10 is formed hollow bulb non-circular or that formation chain 17 passes in handle 10, so that chain 17 cards only get final product in the part of handle 10.
And, though in the foregoing description 1 and 2, insertion section 18 is formed on the inboard of a top side of main part 2, and be formed in the front of the control chamber 2A that stretches out setting upward on the position low on than handle 10, but consider the ease for operation of the insertion operation of jam plate portion 16, also insertion section 18 can be formed on any part place of a top side (being also referred to as facial) of main part 2, for example also can adopt the structure that insertion section 18 is formed on the place, part of compressed part 8.
And, in the foregoing description 1 and 2, extracting from insertion section 18 under the state of jam plate portion 16, if on the part of handle 10, be provided for taking in the incorporating section 10H of jam plate portion 16 and chain 17, and jam plate portion 16 and chain 17 be accommodated among the 10H of this incorporating section, then because jam plate portion 16 and chain 17 can not become the obstacle of the rotation of handle 10, thereby handle 10 is rotated swimmingly.In illustrated handle 10, as shown in Figure 3, the incorporating section 10H of the circle of top opening is formed in the mode of recessed ornamental portion 10S, and shown in the double dot dash line among Fig. 3, by jam plate portion 16 and chain 17 are accommodated among the 10H of incorporating section, thereby reached this purpose.In addition, in above-mentioned other forms of handle, also only need incorporating section with jam plate portion 16 and chain 17 be arranged in the part of handle 10 and get final product.
