[0015] An operating method of a high-pressure sterilizing pot with an auxiliary heating and drying structure comprises the following steps:

[0016] S1. After placing the items on the basket, open the lid on the pot cover, place the basket in the inner tank of the sterilizing pot, and then connect the output end of the fan to the drying pipeline, and the output end of the steam engine to the steam pipeline;

[0017] S2, dehumidification process: close the first valve and the seventh valve to prevent the steam in the heat exchange area from entering the pot top or flowing out to the outside, open the second valve to connect the pot bottom with the heat exchange area, close the fourth valve to seal the bottom of the inner pot, electrically heat the water to form steam, then open the sixth valve to allow the steam to enter the bottom of the pot from the steam pipe, and enter the heat exchange area from the second channel, so that the steam is evenly distributed in the heat exchange area, the steam transfers heat through the inner pot, heats the air that has not been discharged in the inner pot, and the moisture carried by the articles, so that the air expands after absorbing heat, and the water turns into steam after absorbing heat. Since the density of steam is smaller than that of air, the steam flows upward along the inner pot, then open the third valve and the second exhaust port provided on the cover body to allow the steam to be discharged from the sterilizing pot, and the moisture in the airflow is detected by the moisture detector provided at the second exhaust port. When there is no moisture in the airflow, it indicates that the moisture on the articles in the inner pot has been completely evaporated and the articles are in a dry state;

[0018] S3, exhaust process: first open the seventh valve, steam discharges the cold air in the bottom of the lid and the heat exchange area to the outside, then open the fourth valve and the first valve, close a small part of the third valve until the gap of the third valve is smaller than the gap of the first valve, so that the flow rate of steam here is relatively large, and at the same time, because the density of steam is smaller than that of air, it can prevent the air above the inner pot from flowing back into the inner pot through the gap, so that the steam continues to flow upward along the inner pot and gradually squeezes the cold air to move upward, and after the cold air passes through the third valve, it will continue to be squeezed downward by the steam, and then flow out through the first channel and the first exhaust port, so that the cold air in the inner pot and the pot lid is discharged to the outside;

[0019] S4, Sterilization process: close the first valve, the second valve, and the third valve, open the eighth valve and the fourth valve, so that the steam is fully and evenly filled in the inner container, and after a period of time, the items in the basket are fully sterilized, and then the third valve, which is smaller than the gap between the eighth valve and the cover body, is opened, and the steam to be cooled is discharged to the outside through the eighth valve in time;

[0020] S5, Drying process: Finally, close the sixth valve and the eighth valve, open the first valve, the second valve, the fifth valve and the seventh valve, slightly change the third valve and the fourth valve, so that the gap between the third valve and the inner tank is smaller than the gap between the first channel and the second channel and the first valve and the second valve, turn on the fan, so that the airflow generated by the fan enters the inner tank through the drying pipe, and discharges the steam inside the inner tank from the third valve and the fourth valve on the upper and lower sides respectively, and then passes through the first channel and the second channel, so that the steam in the sterilizer is discharged to the outside, and the items on the basket are dried at the same time.

[0021] S6. Finally, open the lid provided on the pot cover and take the basket and items out of the sterilizing pot.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] 1. Before sterilizing the items, the sterilizer is first dehumidified, and the steam is used to transfer heat through the inner tank to heat the air in the inner tank that has not been discharged, as well as the moisture carried by the items, so that the air absorbs heat and expands, and the water absorbs heat and turns into steam. Since the density of steam is smaller than that of air, the steam flows upward along the inner tank, so that the steam is discharged from the sterilizer, and the moisture in the airflow is detected by the moisture detector provided at the second exhaust port. When there is no moisture in the airflow, it indicates that the moisture on the items in the inner tank has been completely evaporated, and the items are in a dry state, thereby preventing the moisture on the items from causing wet packing problems, and improving the sterilization effect of the high-pressure sterilizer;

[0024] At the same time, the cold air inside the sterilizing pot needs to be discharged, and the steam flows upward in the inner pot. Since the density of steam is smaller than that of air, the steam flows upward along the inner pot, and since the gap between the inner pot and the third valve is small, the flow rate of steam here is large, so it can prevent the air above the inner pot from flowing back into the inner pot through the gap, thereby preventing the cold air from flowing back into the inner pot. The steam gradually squeezes the cold air upward, so that after passing through the third valve, the cold air is gradually squeezed downward, and then flows out through the first channel and the first exhaust port, thereby discharging the cold air in the inner pot and the pot cover to the outside, avoiding the air in the sterilizing pot from being completely discharged, resulting in the steam not being saturated, and the coordination of pressure and temperature being destroyed, thereby improving the sterilization effect of the sterilizing pot;

[0025] 2. When sterilizing items, first let the steam fully and evenly fill the inner tank. After fully sterilizing the items in the basket for a period of time, open the third valve that is smaller than the gap between the eighth valve and the cover body, and discharge the steam to be cooled to the outside through the eighth valve in time, while avoiding the reflux of the steam after cooling, thereby improving the sterilization and drying effect of the high pressure sterilizer;

[0026] After sterilization, close the sixth valve and the eighth valve, open the first valve, the second valve, the fifth valve and the seventh valve, and do not completely close the third valve and the fourth valve, so that the gap between the third valve and the fourth valve and the inner tank is smaller than the gap between the first channel and the second channel and the first valve and the second valve, turn on the fan, so that the airflow generated by the fan enters the inner tank through the drying pipe, and the steam inside the inner tank is discharged from the third valve and the fourth valve on the upper and lower sides respectively, and then passes through the first channel and the second channel, so that the steam in the sterilizer is discharged to the outside, and the items on the basket are dried at the same time, and there is no need to dry the items separately later, so as to avoid secondary contamination of the sterilized items and improve the sterilization effect of the high-pressure sterilizer.

[0027] 3. When the opening and closing state of the first valve or the second valve needs to be changed, the restriction on the rotation of the driving ring is released through the cooperation among the driving motor, the driving wheel, the limit block and the limit groove, and then the driving ring rotates around the first channel or the second channel through the cooperation among the driving wheel, the cam, the annular rack and the driving ring, and the first shift block, the second shift block and the column are contacted to push the column to slide between the first shift block and the second shift block, and drive the swing arm to rotate around the valve stem, and drive the flip plate to rotate on the first channel or the second channel, so as to change the opening and closing state of several first valves or several second valves at the same time, without the need to separately set up a power mechanism to drive several first valves or second valves to rotate, thereby reducing the space required for the installation of the power mechanism and the cost required for the production, and at the same time reducing the programming difficulty of controlling the opening and closing of multiple first valves and second valves;

[0028] In addition, each time the driving ring is driven to rotate for a certain angle, the limit block will re-enter the limit groove, and the resistance generated by the contact between the limit block and the limit groove will limit the driving ring from further rotating on the first channel or the second channel, thereby preventing the external force from accidentally driving the driving ring to move and changing the opening and closing relationship of the first valve or the second valve, thereby ensuring the stable operation of the high-pressure sterilizer and improving the sterilization effect of the high-pressure sterilizer;

[0029] 4. When the opening and closing state of the third valve needs to be changed, the cooperation among the driving cylinder, the connecting rod, the bottom of the cover, the turntable and the driven rod is used to drive the turntable to rotate on the valve body, so that the slide groove provided on the turntable contacts the slider provided on the fan-shaped block. The force generated after the contact drives the fan-shaped block to move with the turntable. At the same time, since the guide column provided on the other side of the fan-shaped block is slidably arranged on the arc groove provided on the valve body, the sliding contact between adjacent fan-shaped blocks is coordinated to guide the opening and closing of several fan-shaped blocks on the valve body, so that the ends of several fan-shaped blocks are gathered together to cut off the air flow between the inner tank and the pot cover, so as to avoid steam directly flowing out from the second exhaust port on the valve cover during the sterilization process, thereby improving the sterilization effect of the high-pressure sterilization pot; at the same time, the turntable drives several fan-shaped blocks to open, so as to facilitate the removal of the basket in the inner tank. In addition, the third valve is arranged on the top of the inner tank to prevent the cover from being too heavy and inconvenient for the staff to open or close, thereby improving the sterilization efficiency of the high-pressure sterilization pot;

[0030] In addition, a sealing block is provided on the connecting rod, and a sealing groove slidably connected to the sealing block is provided on the bottom of the cover. The sealing block contacts the sealing strips provided on both sides of the sealing groove, thereby sealing the third valve in the fully opened and closed states, preventing cold air from the outside from entering the interior of the sterilizer through the gap between the connecting rod and the bottom of the cover, thereby improving the sterilization effect of the high-pressure sterilizer and preventing the connecting rod from moving back and forth to wear the sealing strip, thereby reducing the cost and time required for maintaining the third valve; and when the third valve is not completely closed, the internal airflow is quickly discharged to the outside, thereby preventing the airflow from flowing back, thereby sealing the third valve in the not completely closed state;

[0031] 5. When the fourth valve needs to be closed, the sealing cover is driven to slide on the bottom of the pot by the telescopic cylinder until the inclined surface provided on the protrusion contacts the through hole, so that the protrusion smoothly enters the through hole, thereby guiding the sliding of the sealing cover on the fixed cover, and then the first sealing ring and the second sealing ring contact the protrusion and the sealing cover respectively, so as to play a double sealing role, further strengthen the sealing performance of the fourth valve, avoid the steam from entering the inner pot through the fourth valve during the drying process, improve the effect of removing the air that has not been discharged from the inner pot and the moisture carried by the articles during the drying process, and improve the sterilization effect of the high-pressure sterilization pot; at the same time, avoid the relative movement of the sealing cover and the fixed cover, which will cause wear to the first sealing ring and the second sealing ring, thereby reducing the cost and time required for maintaining the fourth valve.

[0046] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0047] The present invention provides a high pressure sterilizing pot with auxiliary heating and drying structure, such as Figure 1 As shown, it comprises a barrel body 1 and a basket 2, the barrel body 1 comprises an inner liner 3 slidably connected to the basket 2, and a pot body 4 sleeved on the outer side of the inner liner 3, the upper and lower ends of the inner liner 3 are respectively provided with a pot cover 5 and a pot bottom 6, the pot cover 5 comprises a cover bottom 7 arranged on the top of the inner liner 3, and a cover body 8 detachably connected to the cover bottom 7, so that the cover body 8 can be freely opened, and the basket 2 and the articles are placed in the inner liner 3, so as to achieve drying of the articles;

[0048] A heat exchange area 9 is formed between the pot body 4 and the inner pot 3. The heat exchange area 9 is filled with steam, and the steam transfers heat through the inner pot 3 to heat the air that has not been discharged in the inner pot 3 and the moisture carried by the articles, so that the air expands after absorbing heat, and the water turns into steam after absorbing heat. Since the density of steam is smaller than that of air, the steam flows upward along the inner pot 3, so that the steam is discharged from the sterilizer, and the articles are in a dry state before sterilization, thereby preventing the moisture on the articles from causing wet packing of the articles;

[0049] A plurality of first channels 10 and a second channel 11 connected to the heat exchange area 9 are respectively provided between the cover bottom 7 and the pot bottom 6 and the pot body 4. The first channel 10 and the second channel 11 are respectively provided with a first valve 12 and a second valve 13 to control the airflow between the heat exchange area 9 and the pot cover 5 and the pot bottom 6.

[0050] The lid bottom 7 and the pot bottom 6 are provided with a third valve 14 and a fourth valve 15 used in conjunction with the upper and lower ends of the inner pot 3 to control the air flow between the inner pot 3, the pot lid 5 and the pot bottom 6;

[0051] The autoclave further includes a drying pipe 16 and a steam pipe 17 respectively connected to the inner pot 3 and the pot bottom 6 and extending to the outside of the pot body 4. The drying pipe 16 and the steam pipe 17 are respectively provided with a fifth valve 18 and a sixth valve 19. The output end of the fan is connected to the drying pipe, and the output end of the steam engine is connected to the steam pipe, so that the articles in the autoclave are dried and sterilized. There is no need to dry the sterilized articles separately later, so as to avoid secondary contamination of the sterilized articles and improve the sterilization effect of the autoclave;

[0052] The pot body 4 is provided with a first exhaust port 20 connected with the heat exchange area 9, and the cover body 8 is provided with a second exhaust port 21. The first exhaust port 20 and the second exhaust port 21 are respectively provided with a seventh valve 22 and an eighth valve 23 to discharge the cold air and steam in the sterilizer to the outside to prevent moisture on the articles from causing wet packing problems on the articles and improve the sterilization effect of the high-pressure sterilizer. The second exhaust port 21 is provided with a moisture detector for detection. For details, please refer to the moisture detector detection of the YF-8600-TH model. The moisture in the airflow is detected by the moisture detector provided at the second exhaust port 21. When there is no moisture in the airflow, it indicates that the moisture on the articles in the liner 3 is completely evaporated and the articles are in a dry state, thereby preventing the moisture on the articles from causing wet packing problems on the articles and improving the sterilization effect of the high-pressure sterilizer.

[0053] Preferably, Figure 1-5 As shown, the first valve 12 and the second valve 13 respectively include valve stems 24 arranged on the first channel 10 and the second channel 11, and a plurality of the valve stems 24 are respectively provided with flap plates 25 for blocking the first channel 10 or the second channel 11, and a swing arm 26 is provided at the end of the valve stem 24, and a column 27 is provided at the end of the swing arm 26, and a driving ring 28 is rotatably connected to the outer side of the first channel 10 or the second channel 11, and a plurality of first shift blocks 29 and second shift blocks 30 are provided on the driving ring 28, and one side of the first shift block 29 and the second shift block 30 are respectively in sliding contact with the two sides of the column 27, and drive the flap plate 25 to rotate on the first channel 10 or the second channel 11, and the first shift block 29 and the second shift block 30 are tilted. It is necessary to change the first valve 12 or the second valve 13 When the valve stem 24 is opened or closed, the driving ring 28 is rotated on the first valve 12 or the second valve 13 to make the first block 29 or the second block 30 contact the column 27. Since the first block 29 and the second block 30 are inclined, the component force generated after the contact pushes the column 27 to slide between the first block 29 and the second block 30, and drives the swing arm 26 to rotate around the valve stem 24, driving the flip plate 25 to rotate on the first channel 10 or the second channel 11, thereby changing the opening and closing states of several first valves 12 or several second valves 13 at the same time. There is no need to separately set up a power mechanism to drive several first valves 12 or second valves 13 to rotate, thereby reducing the space required for installing the power mechanism and the cost required for manufacturing, and at the same time reducing the programming difficulty of controlling the opening and closing of multiple first valves 12 and second valves 13.

[0054] Preferably, Figure 1-5As shown, the driving ring 28 is provided with a plurality of limiting grooves 31, the first channel 10 and the second channel 11 are respectively provided with driving motors 32, the movable end of the driving motor 32 is provided with a driving wheel 33, one side of the driving wheel 33 is provided with a limiting block 34 in contact with the limiting groove 31, the other side of the driving wheel 33 is provided with a cam 35, and the driving ring 28 is provided with an annular rack 36 meshing with the cam 35. The driving motor 32 drives the driving wheel 33 to rotate, so that the limiting block 34 provided on one side of the driving wheel 33 slides out of the limiting groove 31, releasing the restriction on the rotation of the driving ring 28, and then the cam 35 provided on the other side of the driving wheel 33 meshes with the annular rack 36 again. , so that the torque of the driving wheel 33 is transmitted to the driving ring 28, driving the driving ring 28 to rotate around the first channel 10 or the second channel 11, thereby simultaneously changing the opening and closing states of the plurality of first valves 12 or the plurality of second valves 13. In addition, each time the driving ring 28 is driven to rotate by a certain angle, the limit block 34 will re-enter the limit groove 31. The resistance generated by the contact between the limit block 34 and the limit groove 31 will limit the driving ring 28 from further rotating on the first channel 10 or the second channel 11, thereby preventing the external force from accidentally driving the driving ring 28 to move and changing the opening and closing relationship of the first valve 12 or the second valve 13, thereby ensuring the stable operation of the high-pressure sterilizer and improving the sterilization effect of the high-pressure sterilizer.

[0055] Preferably, Figure 6-8 As shown, the third valve 14 includes a valve body 37 arranged on the top of the inner tank 3, a plurality of fan-shaped blocks 38 slidably arranged on the valve body 37, and a turntable 39 rotatably arranged on the valve body 37 to drive the fan-shaped blocks 38 to open or close. The plurality of fan-shaped blocks 38 separate the inner tank 3 and the pot cover 5. When the turntable 39 drives the plurality of fan-shaped blocks 38 to close, the ends of the plurality of fan-shaped blocks 38 are gathered together, thereby separating the air flow between the inner tank 3 and the pot cover 5, and preventing steam from directly flowing out of the second exhaust port 21 on the valve cover during the sterilization process, thereby improving the sterilization effect of the high-pressure sterilization pot; at the same time, the turntable 39 drives the plurality of fan-shaped blocks 38 to open, so as to facilitate taking out the basket 2 in the inner tank 3. In addition, the third valve 14 is arranged on the top of the inner tank 3 to prevent the cover 8 from being too heavy and inconvenient for the staff to open or close, thereby improving the sterilization efficiency of the high-pressure sterilization pot.

[0056] Preferably, Figure 6-8As shown, two adjacent sector blocks 38 are in sliding contact with each other, the valve body 37 is provided with a plurality of arc grooves 40, the turntable 39 is provided with a plurality of mutually connected slide grooves 41, one side of the sector block 38 is provided with a guide column 42 in sliding contact with the arc groove 40, and the other side of the sector block 38 is provided with a slider 43 in sliding contact with the slide groove 41, and the turntable 39 is rotated on the valve body 37, so that the slide groove 41 provided on the turntable 39 is in contact with the slider 43 provided on the sector block 38. The force generated after the contact drives the sector block 38 to move with the turntable 39. At the same time, since the guide column 42 provided on the other side of the sector block 38 is slidably set on the arc groove 40 provided on the valve body 37, the sliding contact between adjacent sector blocks 38 guides the opening and closing of several sector blocks 38 on the valve body 37, thereby improving the stability of the operation of the third valve 14, ensuring the effect of the third valve 14 in isolating the valve cover and the inner tank 3, and improving the sterilization effect of the high-pressure sterilization pot.

[0057] Preferably, Figure 6-8 As shown, one side of the turntable 39 is rotatably connected to a driven rod 44, and a driving cylinder 45 is provided on the cover bottom 7. The movable end of the driving cylinder 45 is rotatably connected to a connecting rod 46, and the end of the connecting rod 46 is rotatably connected to the end of the driven rod 44. The connecting rod 46 is driven to slide on the cover bottom 7 by the driving cylinder 45. Since the two ends of the connecting rod 46 are rotatably connected to the turntable 39 and the driven rod 44 respectively, the turntable 39 is driven to rotate on the valve body 37 to realize the opening and closing of several fan-shaped blocks 38. Several rollers 47 in contact with the turntable 39 are rotatably connected to the cover bottom 7 to reduce the friction between the turntable 39 and the cover bottom 7, so that the turntable 39 can rotate better on the cover bottom 7, and at the same time, it plays a guiding role in the rotation of the turntable 39, thereby improving the stability of the operation of the third valve 14, ensuring the effect of the third valve 14 blocking the valve cover and the inner liner 3, and improving the sterilization effect of the high-pressure sterilization pot.

[0058] Preferably, Figure 6-8As shown, a sealing block 48 is provided on the connecting rod 46, and a sealing groove 49 slidably connected to the sealing block 48 is provided on the cover bottom 7. Sealing strips 50 in contact with the sealing block 48 are respectively provided on both sides of the sealing groove 49, which seal the third valve 14 in the fully opened and closed states, thereby preventing external cold air from entering the interior of the sterilizer through the gap between the connecting rod 46 and the cover bottom 7, thereby improving the sterilization effect of the high-pressure sterilizer, and preventing the connecting rod 46 from moving back and forth to wear the sealing strip 50, thereby reducing the cost and time required for maintaining the third valve 14. When the third valve 14 is not fully closed, the internal airflow is quickly discharged outwards to avoid airflow backflow, thereby sealing the third valve 14 in the not fully closed state. When the third valve 14 is not fully closed, the internal airflow is quickly discharged outwards to avoid airflow backflow, thereby sealing the third valve 14 in the not fully closed state.

[0059] Preferably, Fig. 9 As shown, the fourth valve 15 includes a fixed cover 51 arranged at the bottom of the inner pot 3, and a sealing cover 52 slidably arranged on the pot bottom 6, the fixed cover 51 is provided with a plurality of through holes 53, the sealing cover 52 is provided with a plurality of protrusions 54 slidably connected with the through holes 53, the ends of the protrusions 54 are provided with inclined surfaces 55 in contact with the through holes 53, the fixed cover 51 is respectively provided with a first sealing ring 56 and a plurality of second sealing rings 57, the first sealing ring 56 and the second sealing ring 57 are in contact with the protrusion 54 and the sealing cover 52, and also includes a telescopic cylinder 58 arranged on the pot bottom 6, the movable end of the telescopic cylinder 58 is connected to the sealing cover 52, when the fourth valve 15 needs to be closed, the sealing cover 52 is driven to slide on the pot bottom 6 by the telescopic cylinder 58 until The inclined surface 55 provided on the protrusion 54 contacts the through hole 53, so that the protrusion 54 smoothly enters the through hole 53, thereby guiding the sliding of the sealing cover 52 on the fixed cover 51, and then the first sealing ring 56 and the second sealing ring 57 contact the protrusion 54 and the sealing cover 52 respectively, playing a double sealing role, further strengthening the sealing performance of the fourth valve 15, and preventing the steam from entering the inner liner 3 through the fourth valve 15 during the drying process, improving the effect of removing the air that has not been discharged from the inner liner 3 and the moisture carried by the articles during the drying process, improving the sterilization effect of the high-pressure sterilization pot, and at the same time avoiding the relative movement of the sealing cover 52 and the fixed cover 51, causing wear on the first sealing ring 56 and the second sealing ring 57, thereby reducing the cost and time required for maintaining the fourth valve 15.

[0060] Preferably, Figure 1As shown, the first exhaust port 20 is arranged at the top of the pot body 4, and a partition 59 is provided on the pot body 4. The partition 59 blocks the steam rising into the heat exchange area 9. Since the density of steam is smaller than that of air, the steam first accumulates to the high place of the heat exchange area 9, and then slowly sinks to the first exhaust hole, thereby guiding the steam and preventing the steam from being directly discharged from the first exhaust port 20, thereby ensuring that the steam is fully in contact with the inner tank 3, fully heating the air contained in the inner tank 3 that has not been discharged, as well as the moisture carried by the articles, improving the effect of removing the air that has not been discharged from the inner tank 3 and the moisture carried by the articles during the dehumidification process, and improving the sterilization effect of the high-pressure sterilizer.

[0061] An operating method of a high pressure sterilizing pot with an auxiliary heating and drying structure, such as Figure 1 As shown, the following steps are included:

[0062] S1. After placing the items on the basket 2, open the cover 8 on the pot cover 5, place the basket 2 in the inner tank 3 of the sterilizing pot, and then connect the output end of the fan to the drying pipeline, and the output end of the steam engine to the steam pipeline;

[0063] S2, dehumidification process: close the first valve 12 and the seventh valve 22 to prevent the steam in the heat exchange area 9 from entering the pot top or flowing out to the outside, open the second valve 13 to connect the pot bottom 6 with the heat exchange area 9, close the fourth valve 15 to seal the bottom of the inner pot 3, electrically heat the water to form steam, then open the sixth valve 19 to allow steam to enter the pot bottom 6 from the steam pipe 17 and enter the heat exchange area 9 from the second channel 11, so that the steam is evenly distributed in the heat exchange area 9, and the steam transfers heat through the inner pot 3 to heat the air and objects contained in the inner pot 3 that have not been discharged. The moisture carried on the products causes the air to expand after absorbing heat, and the water turns into steam after absorbing heat. Since the density of steam is smaller than that of air, the steam flows upward along the inner pot 3. Then, the third valve 14 and the second exhaust port 21 provided on the cover body 8 are opened to discharge the steam from the sterilizing pot, and the moisture in the airflow is detected by the moisture detector provided at the second exhaust port 21. When there is no moisture in the airflow, it indicates that the moisture on the products in the inner pot 3 is completely evaporated and the products are in a dry state, thereby preventing the moisture on the products from causing wet packing problems and improving the sterilization effect of the high-pressure sterilizer;

[0064] S3, exhaust process: first open the seventh valve 22, steam discharges the cold air in the cover bottom 7 and the heat exchange area 9 to the outside, then open the fourth valve 15 and the first valve 12, close a small part of the third valve 14, until the gap of the third valve 14 is smaller than the size of the gap of the first valve 12, so that the flow rate of steam here is relatively large, and at the same time, because the density of steam is smaller than that of air, it can prevent the air above the inner pot 3 from flowing back into the inner pot 3 through the gap, so that the steam continues to flow upward along the inner pot 3 and gradually squeezes the cold air to move upward, and after the cold air passes through the third valve 14, it will continue to be squeezed downward by the steam, and then flow out through the first channel 10 and the first exhaust port 20, so as to discharge the cold air in the inner pot 3 and the pot cover 5 to the outside, so as to avoid the air in the sterilizing pot not being completely discharged, resulting in the steam not being saturated, and the coordination of pressure and temperature being destroyed, thereby improving the sterilization effect of the sterilizing pot;

[0065] S4, sterilization process: close the first valve 12, the second valve 13, and the third valve 14, open the eighth valve 23 and the fourth valve 15, so that the steam is fully and evenly filled in the inner container 3, and the items in the basket 2 are fully sterilized for a period of time, and then open the third valve 14 which is smaller than the gap between the eighth valve 23 and the cover 8, and the steam to be cooled is discharged to the outside through the eighth valve 23 in time, and the reflux of the steam after cooling is avoided, thereby improving the sterilization and drying effect of the high pressure sterilizer;

[0066] S5, drying process: finally, the sixth valve 19 and the eighth valve 23 are closed, the first valve 12, the second valve 13, the fifth valve 18 and the seventh valve 22 are opened, the third valve 14 and the fourth valve 15 are not completely closed, so that the gap between the third valve 14 and the fourth valve 15 and the inner liner 3 is smaller than the gap between the first channel 10 and the second channel 11 and the first valve 12 and the second valve 13, and the fan is turned on, so that the airflow generated by the fan enters the inner liner 3 through the drying duct 16, and the steam inside the inner liner 3 is discharged from the third valve 14 and the fourth valve 15 on the upper and lower sides respectively, and then passes through the first channel 10 and the second channel 11, so that the steam in the sterilizer is discharged to the outside, and the items on the basket 2 are dried at the same time, and there is no need to dry the items separately later, so as to avoid secondary contamination of the sterilized items and improve the sterilization effect of the high-pressure sterilizer.

[0067] S6. Finally, open the cover 8 provided on the pot cover 5, and take the basket 2 and the articles out of the sterilizing pot.

[0068] Example 1

[0069] The present invention provides a high pressure sterilizing pot with auxiliary heating and drying structure and an operation method thereof, such as Figure 1As shown, before using the high pressure sterilizer for sterilization, first place the articles on the basket 2, then open the cover 8 on the pot cover 5, place the basket 2 in the inner pot 3 of the sterilizer, then connect the output end of the fan to the drying pipeline, and connect the output end of the steam engine to the steam pipeline;

[0070] The process of sterilization using an autoclave is:

[0071] Dehumidification process: close the first valve 12 and the seventh valve 22 to prevent the steam in the heat exchange area 9 from entering the pot top or flowing out to the outside, open the second valve 13 to connect the pot bottom 6 with the heat exchange area 9, close the fourth valve 15 to seal the bottom of the inner pot 3, and electrically heat the water to form steam. Then open the sixth valve 19 to allow steam to enter the pot bottom 6 from the steam pipe 17 and enter the heat exchange area 9 from the second channel 11, so that the steam is evenly distributed in the heat exchange area 9, and the steam transfers heat through the inner pot 3 to heat the air and objects in the inner pot 3 that have not been discharged. The moisture carried on the air causes the air to expand after absorbing heat, and the water turns into steam after absorbing heat. Since the density of steam is smaller than that of air, the steam flows upward along the inner pot 3. Then, the third valve 14 and the second exhaust port 21 provided on the cover body 8 are opened to discharge the steam from the sterilizing pot, and the moisture in the airflow is detected by the moisture detector provided at the second exhaust port 21. When there is no moisture in the airflow, it indicates that the moisture on the articles in the inner pot 3 is completely evaporated and the articles are in a dry state, thereby preventing the moisture on the articles from causing wet packing problems and improving the sterilization effect of the high-pressure sterilizer;

[0072] Exhaust process: first open the seventh valve 22, steam discharges the cold air in the cover bottom 7 and the heat exchange area 9 to the outside, then open the fourth valve 15 and the first valve 12, and close a small part of the third valve 14 until the gap of the third valve 14 is smaller than the size of the gap of the first valve 12, so that the flow rate of steam here is relatively large. At the same time, since the density of steam is smaller than that of air, it can prevent the air above the inner pot 3 from flowing back into the inner pot 3 through the gap, so that the steam continues to flow upward along the inner pot 3 and gradually squeezes the cold air to move upward. After the cold air passes through the third valve 14, it will continue to be squeezed downward by the steam, and then flow out through the first channel 10 and the first exhaust port 20, so as to discharge the cold air in the inner pot 3 and the pot cover 5 to the outside, so as to avoid the air in the sterilizing pot not being completely discharged, resulting in the steam not being saturated, and the coordination of pressure and temperature being destroyed, thereby improving the sterilization effect of the sterilizing pot;

[0073] Sterilization process: close the first valve 12, the second valve 13, and the third valve 14, open the eighth valve 23 and the fourth valve 15, so that the steam is fully and evenly filled in the inner container 3, and after a period of time, the third valve 14 smaller than the gap between the eighth valve 23 and the cover 8 is opened, and the steam to be cooled is discharged to the outside through the eighth valve 23 in time, and the reflux of the steam after cooling is avoided, thereby improving the sterilization and drying effect of the high pressure sterilizer;

[0074] Drying process: Finally, close the sixth valve 19 and the eighth valve 23, open the first valve 12, the second valve 13, the fifth valve 18 and the seventh valve 22, and partially close the third valve 14 and the fourth valve 15, so that the gap between the third valve 14 and the fourth valve 15 and the inner tank 3 is smaller than the gap between the first channel 10 and the second channel 11 and the first valve 12 and the second valve 13, turn on the fan, so that the airflow generated by the fan enters the inner tank 3 through the drying pipe 16, and the steam inside the inner tank 3 is discharged from the third valve 14 and the fourth valve 15 on the upper and lower sides respectively, and then passes through the first channel 10 and the second channel 11, so that the steam in the sterilizer is discharged to the outside, and the items on the basket 2 are dried at the same time, and there is no need to dry the items separately in the future, so as to avoid secondary contamination of the sterilized items and improve the sterilization effect of the high-pressure sterilizer.

[0075] Example 2

[0076] On the basis of Example 1, Figure 2-5 As shown in the figure, when the opening and closing state of the first valve 12 or the second valve 13 needs to be changed, the driving motor 32 drives the driving wheel 33 to rotate, so that the limit block 34 provided on one side of the driving wheel 33 slides out of the limit groove 31, and the restriction on the rotation of the driving ring 28 is released. Then, the cam 35 provided on the other side of the driving wheel 33 is re-engaged with the annular rack 36, so that the torque of the driving wheel 33 is transmitted to the driving ring 28, driving the driving ring 28 to rotate around the first channel 10 or the second channel 11, so that the first shift block 29 or the second shift block 30 contacts the column 27. The block 30 is tilted, and the component force generated after contact pushes the column 27 to slide between the first shift block 29 and the second shift block 30, and drives the swing arm 26 to rotate around the valve stem 24, driving the flip plate 25 to rotate on the first channel 10 or the second channel 11, thereby changing the opening and closing state of a plurality of first valves 12 or a plurality of second valves 13 at the same time, and there is no need to separately set a power mechanism to drive a plurality of first valves 12 or second valves 13 to rotate, thereby reducing the space required for the installation of the power mechanism and the cost required for the production, and at the same time reducing the programming difficulty of controlling the opening and closing of a plurality of first valves 12 and second valves 13;

[0077] In addition, each time the driving ring 28 is driven to rotate a certain angle, the limit block 34 will re-enter the limit groove 31. The resistance generated by the contact between the limit block 34 and the limit groove 31 will limit the driving ring 28 from further rotating on the first channel 10 or the second channel 11, thereby preventing external force from accidentally driving the driving ring 28 to move and changing the opening and closing relationship of the first valve 12 or the second valve 13, thereby ensuring the stable operation of the high-pressure sterilizer and improving the sterilization effect of the high-pressure sterilizer.

[0078] Example 3

[0079] On the basis of Example 1, Figure 6-8 As shown, when the opening and closing state of the third valve 14 needs to be changed, the connecting rod 46 is driven to slide on the cover bottom 7 by driving the cylinder 45. Since the two ends of the connecting rod 46 are rotatably connected with the rotating disk 39 and the driven rod 44 respectively, the rotating disk 39 is driven to rotate on the valve body 37, so that the sliding groove 41 provided on the rotating disk 39 contacts the sliding block 43 provided on the sector block 38. The force generated after the contact drives the sector block 38 to move with the rotating disk 39. At the same time, since the guide column 42 provided on the other side of the sector block 38 is slidably set on the arc groove 40 provided on the valve body 37, the sliding contact between adjacent sector blocks 38 is cooperated. It plays a guiding role in the opening and closing of the plurality of fan-shaped blocks 38 on the valve body 37, so that the ends of the plurality of fan-shaped blocks 38 are gathered together, blocking the air flow between the inner pot 3 and the pot cover 5, and preventing the steam from directly flowing out from the second exhaust port 21 on the valve cover during the sterilization process, thereby improving the sterilization effect of the high-pressure sterilizer; at the same time, the plurality of fan-shaped blocks 38 are driven to open by the turntable 39, so as to facilitate taking out the basket 2 in the inner pot 3. In addition, the third valve 14 is arranged on the top of the inner pot 3 to prevent the cover 8 from being too heavy and inconvenient for the staff to open or close, thereby improving the sterilization efficiency of the high-pressure sterilizer;

[0080] In addition, a sealing block 48 is provided on the connecting rod 46, and a sealing groove 49 slidably connected to the sealing block 48 is provided on the cover bottom 7. The sealing block 48 contacts the sealing strips 50 respectively provided on both sides of the sealing groove 49, thereby sealing the third valve 14 in the fully opened and closed states, preventing external cold air from entering the interior of the sterilizer through the gap between the connecting rod 46 and the cover bottom 7, thereby improving the sterilization effect of the high-pressure sterilizer and preventing the connecting rod 46 from moving back and forth to wear the sealing strip 50, thereby reducing the cost and time required for maintaining the third valve 14; and when the third valve 14 is not fully closed, the internal airflow is quickly discharged to the outside to prevent the airflow from flowing back, thereby sealing the third valve 14 in the not fully closed state.

[0081] Example 4

[0082] On the basis of Example 1, Fig. 9As shown, when the fourth valve 15 needs to be closed, the sealing cover 52 is driven to slide on the pot bottom 6 by the telescopic cylinder 58 until the inclined surface 55 provided on the protrusion 54 contacts the through hole 53, so that the protrusion 54 smoothly enters the through hole 53, thereby guiding the sliding of the sealing cover 52 on the fixed cover 51, and then the first sealing ring 56 and the second sealing ring 57 contact the protrusion 54 and the sealing cover 52 respectively, so as to play a double sealing role, further strengthen the sealing performance of the fourth valve 15, avoid the steam from entering the inner pot 3 through the fourth valve 15 during the drying process, improve the effect of removing the air that has not been discharged from the inner pot 3 and the moisture carried by the articles during the drying process, improve the sterilization effect of the high-pressure sterilization pot, and at the same time avoid the relative movement of the sealing cover 52 and the fixed cover 51, which causes wear to the first sealing ring 56 and the second sealing ring 57, thereby reducing the cost and time required for maintaining the fourth valve 15.

10. The method for operating a high pressure sterilizing pot with an auxiliary heating and drying structure according to claim 1, characterized in that: The following steps are involved: S1. After placing the articles on the basket (2), open the cover (8) on the pot cover (5), place the basket (2) in the inner pot (3) of the sterilizing pot, and then connect the output end of the fan to the drying pipeline and the output end of the steam engine to the steam pipeline; S2, dehumidification process: close the first valve (12) and the seventh valve (22) to prevent the steam in the heat exchange area (9) from entering the pot top or flowing out to the outside, open the second valve (13) to connect the pot bottom (6) with the heat exchange area (9), close the fourth valve (15) to seal the bottom of the inner pot (3), electrically heat the water to form steam, then open the sixth valve (19) to allow the steam to enter the pot bottom (6) from the steam pipe (17) and enter the heat exchange area (9) from the second channel (11), so that the steam is evenly distributed in the heat exchange area (9), and the steam passes through the inner pot ( 3) transferring heat to heat the air in the inner container (3) that has not been exhausted and the moisture carried by the articles, so that the air absorbs heat and expands, and the water absorbs heat and turns into steam. Since the density of steam is smaller than that of air, the steam flows upward along the inner container (3). Then, the third valve (14) and the second exhaust port (21) provided on the cover (8) are opened to allow the steam to be exhausted from the sterilizing pot, and the moisture in the air flow is detected by a moisture detector provided on the second exhaust port (21). When there is no moisture in the air flow, it indicates that the moisture on the articles in the inner container (3) has been completely evaporated and the articles are in a dry state. S3, exhaust process: first open the seventh valve (22), steam exhausts the cold air in the lid bottom (7) and the heat exchange area (9) to the outside, then open the fourth valve (15) and the first valve (12), close a small part of the third valve (14), until the gap of the third valve (14) is smaller than the size of the gap of the first valve (12), so that the flow rate of steam here is relatively large. At the same time, because the density of steam is smaller than that of air, it can prevent the air above the inner pot (3) from flowing back into the inner pot (3) through the gap, so that the steam continues to flow upward along the inner pot (3) and gradually squeezes the cold air to move upward. After the cold air passes through the third valve (14), it will continue to be squeezed downward by the steam and then flow out through the first channel (10) and the first exhaust port (20), thereby exhausting the cold air in the inner pot (3) and the pot lid (5) to the outside; S4, sterilization process: close the first valve (12), the second valve (13), and the third valve (14), open the eighth valve (23) and the fourth valve (15), so that the steam can fully and evenly fill the inner container (3), and sterilize the items in the basket (2) for a period of time, and then open the third valve (14) which is smaller than the gap between the eighth valve (23) and the cover body (8), and discharge the steam to be cooled to the outside through the eighth valve (23) in time; S5, drying process: finally, the sixth valve (19) and the eighth valve (23) are closed, the first valve (12), the second valve (13), the fifth valve (18) and the seventh valve (22) are opened, the third valve (14) and the fourth valve (15) are slightly changed, so that the gap between the third valve (14) and the inner container (3) is smaller than the gap between the first channel (10) and the second channel (11) and the first valve (12) and the second valve (13), the fan is turned on, so that the airflow generated by the fan enters the inner container (3) through the drying pipe (16), and the steam inside the inner container (3) is discharged from the third valve (14) and the fourth valve (15) on the upper and lower sides respectively, and then passes through the first channel (10) and the second channel (11), so that the steam in the sterilizer is discharged to the outside, and the items on the basket (2) are dried at the same time. S6. Finally, open the cover (8) provided on the pot cover (5) and take the basket (2) and the articles out of the sterilizing pot.
