Description

Technical Field

[0001] The present application relates to the field of biomedical instrument sterilization, and in particular to an instrument sterilization transfer cabinet suitable for a biological clean environment. Background Art

[0002] Biomedical devices need to be sterilized mainly to ensure that they are sterile before use, prevent cross infection, and ensure the safety of patients and medical staff. Sterilization can effectively kill all microorganisms on medical devices to avoid becoming a source of infection. At the same time, this is also in line with the requirements of medical regulations, especially medical devices that enter human tissues and sterile organs must be sterilized. Through sterilization, the risk of infection during surgery or diagnosis and treatment can be reduced, and medical disputes and medical accidents can be reduced.

[0003] Most of the existing technologies use moist heat sterilization, and the structure of the sterilization device used includes an inner liner, an outer shell, a control system and a piping system. The inner liner serves as a steam container and is composed of components such as a heater, a tray and a water tank to ensure that the steam is sufficient and evenly distributed; the outer shell is made of stainless steel to provide solid protection and good sealing to prevent steam leakage. The control system integrates sensors such as temperature and pressure to accurately control various parameters in the sterilization process, such as temperature, pressure and time, to ensure the sterilization effect. The piping system connects the inner liner and the outside, including a steam input pipe, a temperature sensor, etc., which is responsible for the introduction of steam and real-time monitoring of sterilization parameters. These structures work together to ensure that the moist heat sterilization device can efficiently and safely complete the sterilization task of medical devices, and finally the sterilized instruments can be naturally dried.

[0004] For the above-mentioned related technologies, the staff needs to place the instruments on a tray. When performing wet heat sterilization on the instruments, the sterilization effect on the contact surface of the instruments and the tray may be weak, and natural air drying is more time-consuming, which reduces the efficiency of the overall sterilization operation of the instruments. Moreover, when the internal structure of the instruments is more complicated, the sterilization steam accumulated inside the instruments may be difficult to dry, so improvements are made to this end. Summary of the invention

[0005] In order to reduce dead corners when sterilizing instruments, improve the overall efficiency of sterilizing instruments, and improve the sterilization and drying effects of the internal structures of instruments, the present application provides an instrument sterilization transfer cabinet suitable for a biological clean environment.

[0006] The present application provides an instrument sterilization transfer cabinet suitable for a biological clean environment, which adopts the following technical solution: An instrument sterilization transfer cabinet suitable for a biological clean environment comprises a box body, wherein a first partition, a second partition, a third partition and a fourth partition are arranged in intervals in the box body, the second partition and the third partition are both arranged between the first partition and the fourth partition, and the second partition is arranged between the first partition and the third partition; A feeding bin is formed between the side of the first partition away from the second partition and the inner wall of the box, a disinfection bin is formed between the first partition, the second partition and the inner wall of the box, a drying bin is formed between the second partition, the third partition and the inner wall of the box, a detection bin is formed between the third partition, the fourth partition and the inner wall of the box, and a discharging bin is formed between the fourth partition and the inner wall of the box; The box body is also provided with a first conveyor belt, a second conveyor belt, a third conveyor belt and a fourth conveyor belt, wherein the first conveyor belt is partially provided in the feeding bin and partially penetrates the first partition and is provided in the disinfection bin, the second conveyor belt is partially provided in the disinfection bin and partially penetrates the second partition and is provided in the drying bin, the third conveyor belt is partially provided in the drying bin and partially penetrates the third partition and is provided in the detection bin, the fourth conveyor belt is partially provided in the detection bin and partially penetrates the fourth partition and is provided in the discharging bin; Between the first conveyor belt and the second conveyor belt is a sterilization station for sterilizing instruments, between the second conveyor belt and the third conveyor belt is a drying station for drying sterilized instruments, and between the third conveyor belt and the fourth conveyor belt is a detection station for detecting whether the instruments are completely dried; The box body is provided with a first moving mechanism for clamping and moving the instrument within the box body and rotating it in one direction at the disinfection station, the drying station and the inspection station, and a second moving mechanism for rotating it in another direction.

[0007] By adopting the above technical solution, the instrument is placed on the first conveyor belt, the first conveyor belt is started, the instrument is transported into the disinfection bin by the first conveyor belt, and the instrument is transported to the disinfection station for rotational disinfection in two directions under the action of the first moving mechanism or the second moving mechanism, thereby reducing the disinfection dead angle of the instrument. When there is a structure inside the instrument, the flushing effect inside the instrument can also be improved. The clamping switching in two directions can avoid the clamping dead angle caused by the clamping block clamping the instrument. After the instrument is disinfected, it is also necessary to dry the instrument. The instrument is transported to the second conveyor belt by the first moving mechanism or the second moving mechanism, and is transported to the drying bin by the second conveyor belt, and is transported to the disinfection station under the action of the first moving mechanism or the second moving mechanism. The instrument is transported to the drying station for rotational drying in two directions. The rotation of the instrument can also produce a centrifugal effect, so the disinfectant accumulated inside the instrument can be centrifugally thrown out, thereby improving the drying efficiency and drying effect when drying the instrument. After the drying is completed, the instrument is transported to the third conveyor belt by the first moving mechanism or the second moving mechanism, and the third conveyor belt transports the instrument to the inspection bin, and under the action of the first moving mechanism or the second moving mechanism, the instrument is transported to the inspection station for residual detection of the flushing liquid, and thus it is determined whether the instrument is completely dried. If the flushing liquid residue is detected, the above operation is repeated until no flushing liquid residue is detected, which means that the flushing and drying are complete, thereby improving the disinfection and sterilization effect of the instrument.

[0008] Optionally, the first moving mechanism includes a first moving component and a second moving component, the first moving component and the second moving component are symmetrically arranged, and the first moving component is arranged together with the second moving component, the first moving component includes a driving motor, a screw rod, a sliding block and a clamping and rotating structure, a moving groove is opened on the box body, the sliding block is slidably arranged in the moving groove, the driving motor is arranged on the side wall of the box body, one end of the screw rod is connected to the output shaft of the driving motor, and the other end is rotatably arranged on the box body, and the sliding block is threadedly connected to the screw rod, and the clamping and rotating structure is arranged on the sliding block for clamping and rotating the instrument in two directions.

[0009] By adopting the above technical scheme, the driving motor is started, and the starting motor drives the screw rod to rotate. Due to the threaded connection between the screw rod and the sliding block, the sliding block can be driven to move, thereby realizing the movement of the clamping and rotating component structure on the moving block. The first moving component is arranged with the second moving component, and the first moving component and the second moving component are arranged symmetrically. Therefore, the instrument can be clamped and fixed by the clamping and rotating component, and the instrument can be rotated while moving. The first moving mechanism is arranged with the second moving mechanism to realize clamping and rotation of the instrument in two directions, thereby reducing the dead angle of disinfection of the instrument. When there is a structure inside the instrument, it can also improve the flushing and sterilization effect of the inside of the instrument. The clamping switching in two directions can avoid the clamping dead angle caused by the clamping block clamping the instrument. When the instrument rotates, a centrifugal effect can also be generated, so the disinfectant accumulated in the instrument can be centrifuged out, thereby improving the drying efficiency and drying effect when drying the instrument.

[0010] Optionally, the clamping and rotating structure includes an electric telescopic rod, a multi-stage telescopic sleeve, a gear ring, a clamping block and a rack, the fixed end of the electric telescopic rod is arranged on the sliding block, the telescopic end of the electric telescopic rod passes through the sliding block and is arranged in the box body, the fixed end of the multi-stage telescopic sleeve is rotatably arranged on a surface of the sliding block away from the driving motor, the telescopic end of the electric telescopic rod is rotatably connected to an end of the innermost sleeve in the multi-stage telescopic sleeve away from the electric telescopic rod, the clamping block is arranged on an end of the innermost sleeve in the multi-stage telescopic sleeve away from the electric telescopic rod, the rack is arranged in the box body, the gear ring is arranged on the outermost sleeve in the multi-stage telescopic sleeve, and the rack and the gear ring are meshed with each other.

[0011] By adopting the above technical solution, since the rack and the gear ring are meshed with each other, the fixed end of the multi-stage telescopic sleeve is rotatably set on the sliding block. Therefore, when the sliding block drives the multi-stage telescopic sleeve to move, the multi-stage telescopic sleeve can be rotated to start the electric telescopic rod. Since the telescopic end of the electric telescopic rod is rotatably connected to the end of the innermost sleeve in the multi-stage telescopic sleeve away from the electric telescopic rod, the extension of the telescopic end of the electric telescopic rod can drive the extension of the multi-stage telescopic sleeve, thereby clamping the instrument. The clamping of the instrument is completed by the clamping block and the rotation of the multi-stage telescopic sleeve is achieved by the gear ring and the rack, so that the clamping and rotation of the instrument can be achieved.

[0012] Optionally, blocking blocks are provided at both ends of the sliding block along the length of the box body, and the blocking blocks are slidably set in the movable groove, and the length of the blocking blocks is greater than that of the disinfection chamber, the drying chamber and the detection chamber.

[0013] By adopting the above technical scheme, the sealing block can seal the disinfection chamber when the clamping block is located in the disinfection chamber, thereby improving the sealing effect of the disinfection chamber; and can seal the drying chamber when the clamping block is located in the drying chamber, thereby improving the sealing effect of the drying chamber, thereby reducing the leakage of high-temperature steam and high-temperature drying gas and reducing its impact on the working environment of the staff.

[0015] By adopting the above technical scheme, when the air inlet pipe in the disinfection chamber inputs high-temperature steam to the side of the movable plate close to the nozzle, the air pressure on the side of the movable plate close to the nozzle increases, which will cause the movable plate to move to the side away from the nozzle. At this time, the spring is compressed, the hole cleaning needle is separated from the nozzle, and the high-temperature disinfection gas sprayed from the nozzle disinfects the instruments on the disinfection station. When the high-temperature steam is stopped from being input to the side of the movable plate close to the nozzle, the spring is extended, and the hole cleaning needle is extended into the nozzle, thereby avoiding the nozzle being blocked due to long-term use of the nozzle. Similarly, the instruments on the drying station are dried by the nozzle in the drying chamber. The dried instruments are moved to the detection station for detection by the first moving mechanism or the second moving mechanism. The ultraviolet lamp is turned on. If the light sensor detects the presence of a fluorescent spot, it means that the drying is incomplete or the cleaning is not thorough enough.

[0019] By adopting the above technical solution, the electric lifting rod is started, and the telescopic end of the electric lifting rod will drive the mounting bar to rise and fall, thereby realizing the lifting and lowering of the gate. When the gate is closed, the end in contact with the first conveyor belt is clamped between two adjacent groups of horizontal bars, thereby further improving the sealing effect between the gate and the first conveyor belt, the second conveyor belt, the third conveyor belt and the fourth conveyor belt.

[0020] Optionally, an accordion cover is provided on the movable groove.

[0021] By adopting the above technical solution, the accordion cover can further improve the overall sealing performance of the box, thereby further reducing the impact of high-temperature steam and high-temperature drying gas on the working environment of the staff.

The device can also generate a centrifugal effect when rotating, so the disinfectant accumulated inside the device can be centrifugally thrown out, thereby improving the drying efficiency and drying effect of the device; 3. After drying is completed, the device is transported to the third conveyor belt by the first moving mechanism or the second moving mechanism, and the device is transported to the inspection bin by the third conveyor belt, and the device is transported to the inspection station by the first moving mechanism or the second moving mechanism to detect the residual flushing liquid, and thus determine whether the device is completely dried. If the residual flushing liquid is detected, the above operation is repeated until no residual flushing liquid is detected, indicating that the flushing and drying is complete, thereby improving the disinfection and sterilization effect of the device; 4. When the air inlet pipe in the disinfection chamber inputs high-temperature steam to the side of the movable plate close to the nozzle, the air pressure on the side of the movable plate close to the nozzle increases, causing the movable plate to move to the side away from the nozzle.

[0026] The following is combined with Figure 1-7 This application is described in further detail.

[0027] The present application embodiment discloses an instrument sterilization transfer cabinet suitable for a biological clean environment, referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 A device sterilization transfer cabinet suitable for a biological clean environment comprises a box body 1, wherein a first partition 11, a second partition 12, a third partition 13 and a fourth partition 14 are arranged in intervals in the box body 1, the second partition 12 and the third partition 13 are arranged between the first partition 11 and the fourth partition 14, and the second partition 12 is arranged between the first partition 11 and the third partition 13; a feeding bin 15 is arranged between the side of the first partition 11 away from the second partition 12 and the inner wall of the box body 1, a disinfection bin 16 is arranged between the first partition 11, the second partition 12 and the inner wall of the box body 1, a drying bin 17 is arranged between the second partition 12, the third partition 13 and the inner wall of the box body 1, a detection bin 18 is arranged between the third partition 13, the fourth partition 14 and the inner wall of the box body 1, and a discharge bin 19 is arranged between the fourth partition 14 and the inner wall of the box body 1.

[0028] The box body 1 is also provided with a first conveyor belt 2, a second conveyor belt 3, a third conveyor belt 4 and a fourth conveyor belt 5. The first conveyor belt 2 is partially arranged in the feeding bin 15, and partially penetrates the first partition 11 and is arranged in the disinfection bin 16.

The fourth conveyor belt 5 is partially arranged in the detection bin 18, and partially penetrates the fourth partition 1 4 is arranged in the discharge bin 19; between the first conveyor belt 2 and the second conveyor belt 3 is a disinfection station for disinfecting the instrument, between the second conveyor belt 3 and the third conveyor belt 4 is a drying station for drying the sterilized instrument, and between the third conveyor belt 4 and the fourth conveyor belt 5 is a detection station for detecting whether the instrument is completely dried; the box body 1 is provided with a first moving mechanism 6 and a second moving mechanism 7, the first moving mechanism 6 and the second moving mechanism 7 are arranged perpendicular to each other, and the first moving mechanism 6 is arranged with the second moving mechanism 7.

[0029] Place the instrument on the first conveyor belt 2, start the first conveyor belt 2, transport the instrument into the disinfection bin 16 through the first conveyor belt 2, and transport the instrument to the disinfection station for rotational disinfection in two directions under the action of the first moving mechanism 6 or the second moving mechanism 7, thereby reducing the disinfection blind spots of the instrument. When there are structures inside the instrument, the flushing effect inside the instrument can also be improved. The clamping switching in two directions can avoid the clamping blind spots caused by the clamping block 6144 when clamping the instrument. After the instrument is disinfected, it is also necessary to dry the instrument. The instrument is transported to the second conveyor belt 3 through the first moving mechanism 6 or the second moving mechanism 7, and is transported to the drying bin 17 by the second conveyor belt 3, and is placed under the action of the first moving mechanism 6 or the second moving mechanism 7. The instrument is transported to the drying station for rotational drying in two directions. The rotation of the instrument can also produce a centrifugal effect, so the disinfectant accumulated inside the instrument can be centrifuged out, thereby improving the drying efficiency and drying effect when drying the instrument. After drying, the instrument is transported to the third conveyor belt 4 by the first moving mechanism 6 or the second moving mechanism 7, and the third conveyor belt 4 transports the instrument to the detection bin 18, and under the action of the first moving mechanism 6 or the second moving mechanism 7, the instrument is transported to the detection station for residual detection of the flushing liquid, and thus it is determined whether the instrument is completely dried. If the flushing liquid residue is detected, the above operation is repeated until no flushing liquid residue is detected, which means that the flushing and drying are complete, thereby improving the disinfection and sterilization effect of the instrument.

[0030] Reference Figure 5The first moving mechanism 6 includes a first moving component 61 and a second moving component 62. The first moving component 61 and the second moving component 62 are symmetrically arranged, and the first moving component 61 is arranged together with the second moving component 62. The first moving component 61 includes a driving motor 611, a screw rod 612, a sliding block 613 and a clamping and rotating structure 614. A moving groove is provided on the box body 1, and the sliding block 613 is slidably arranged in the moving groove. The driving motor 611 is arranged on the side wall of the box body 1. One end of the screw rod 612 is connected to the output shaft of the driving motor 611, and the other end is rotatably arranged on the box body 1. The sliding block 613 is threadedly connected to the screw rod 612. The clamping and rotating structure 614 is arranged on the sliding block 613, which is used to clamp and rotate the instrument in two directions. An accordion cover 10 is arranged on the moving groove.

[0031] Start the driving motor 611, and the starting motor drives the screw rod 612 to rotate. Since the screw rod 612 and the sliding block 613 are threadedly connected, the sliding block 613 can be driven to move, thereby realizing the movement of the clamping and rotating component structure on the moving block. The first moving component 61 is arranged with the second moving component 62, and the first moving component 61 and the second moving component 62 are arranged symmetrically, so the instrument can be clamped and fixed by the clamping and rotating component, and the instrument can be rotated while moving. The first moving mechanism 6 is arranged with the second moving mechanism 7 to realize the clamping and rotation of the instrument in two directions, thereby reducing the sterilization dead angle of the instrument. When there is a structure inside the instrument, the flushing effect inside the instrument can also be improved. The clamping switching in two directions can avoid the clamping dead angle generated when the clamping block 6144 clamps the instrument. When the instrument rotates, a centrifugal effect can also be generated, so the disinfectant accumulated in the instrument can be centrifuged out, thereby improving the drying efficiency and drying effect when drying the instrument. The accordion cover 10 can further improve the overall sealing performance of the box 1, thereby further reducing the impact of high-temperature steam and high-temperature drying gas on the working environment of the staff.

[0032] Reference Figure 5The clamping and rotating structure 614 includes an electric telescopic rod 6141, a multi-stage telescopic sleeve 6142, a gear ring 6143, a clamping block 6144 and a rack 6145. The fixed end of the electric telescopic rod 6141 is arranged on the sliding block 613. The telescopic end of the electric telescopic rod 6141 passes through the sliding block 613 and is arranged in the box body 1. The fixed end of the multi-stage telescopic sleeve 6142 is rotatably arranged on the side of the sliding block 613 away from the driving motor 611. The telescopic end of the retractable rod 6141 is rotatably connected to the end of the innermost sleeve in the multi-stage telescopic sleeve 6142 away from the electric telescopic rod 6141, the clamping block 6144 is arranged on the end of the innermost sleeve in the multi-stage telescopic sleeve 6142 away from the electric telescopic rod 6141, the rack 6145 is arranged in the box body 1, the gear ring 6143 is arranged on the outermost sleeve in the multi-stage telescopic sleeve 6142, and the rack 6145 and the gear ring 6143 are engaged with each other.

[0033] Since the rack 6145 and the gear ring 6143 are meshed with each other, the fixed end of the multi-stage telescopic sleeve 6142 is rotatably set on the sliding block 613. Therefore, when the sliding block 613 drives the multi-stage telescopic sleeve 6142 to move, the multi-stage telescopic sleeve 6142 can be rotated, and the electric telescopic rod 6141 is started. Since the telescopic end of the electric telescopic rod 6141 is rotatably connected to the end of the innermost sleeve in the multi-stage telescopic sleeve 6142 away from the electric telescopic rod 6141, the extension of the telescopic end of the electric telescopic rod 6141 can drive the extension of the multi-stage telescopic sleeve 6142, thereby clamping the instrument. The clamping of the instrument is completed by the clamping block 6144 and the rotation of the multi-stage telescopic sleeve 6142 is achieved by the gear ring 6143 and the rack 6145, so that the clamping and rotation of the instrument can be achieved.

[0034] Reference Figure 5 The sliding block 613 is provided with a blocking block 615 at both ends along the length of the box body 1, and the blocking block 615 is slidably arranged in the moving groove, and the length of the blocking block 615 is greater than the sterilization chamber 16, the drying chamber 17 and the detection chamber 18. The blocking block 615 can block the sterilization chamber 16 when the clamping block 6144 is located in the sterilization chamber 16, thereby improving the sealing effect of the sterilization chamber 16, and can block the drying chamber 17 when the clamping block 6144 is located in the drying chamber 17, thereby improving the sealing effect of the drying chamber 17, thereby reducing the leakage of high-temperature steam and high-temperature drying gas, and reducing the impact on the working environment of the staff.

[0035] A plurality of water outlet strips 161 are arranged on the inner wall of the disinfection chamber 16, and a plurality of nozzles 162 for spraying high-temperature disinfection steam containing fluorescent material are arranged on the water outlet strips 161. A mobile chamber is opened in the water outlet strips 161, and a movable plate 163 is slidably arranged in the mobile chamber. A hole cleaning needle 164 is arranged on the side of the movable plate 163 close to the nozzle 162, and a spring 165 is arranged on the side of the movable plate 163 away from the hole cleaning needle 164. An air inlet pipe 166 is arranged on the box body 1, and the air inlet pipe 166 is connected to a side of the movable plate 163 close to the nozzle 162. The drying chamber 17 is arranged in the same manner as the disinfection chamber 16, and the nozzle 162 in the drying chamber 17 is used to spray high-temperature dry airflow. A plurality of ultraviolet lamps 181 for making residual fluorescent material emit light, and a photosensitive element 182 for detecting the emitted residual fluorescent material are arranged on the inner wall of the detection chamber 18.

[0036] Reference Figure 6 and Figure 7 When the air inlet pipe 166 in the disinfection chamber 16 inputs high-temperature steam to the side of the movable plate 163 close to the nozzle 162, the air pressure on the side of the movable plate 163 close to the nozzle 162 increases, which will cause the movable plate 163 to move to the side away from the nozzle 162. At this time, the spring 165 is compressed, the hole cleaning needle 164 is separated from the nozzle 162, and the high-temperature disinfection gas sprayed from the nozzle 162 disinfects the equipment on the disinfection station. When the high-temperature steam is stopped from being input to the side of the movable plate 163 close to the nozzle 162, the spring 165 is extended. The hole cleaning needle 164 extends into the nozzle 162 to avoid the nozzle 162 from being blocked due to long-term use. Similarly, the nozzle 162 is used to dry the equipment on the drying station in the drying chamber 17. The dried equipment is moved to the detection station for detection through the first moving mechanism 6 or the second moving mechanism 7. The ultraviolet lamp 181 is turned on. If the light sensor 182 detects the presence of a fluorescent spot, it means that the drying is incomplete or the cleaning is not thorough enough. The cleaning and drying are repeated until the fluorescent spot is no longer detected.

[0037] The bottom of the box body 1 is provided with a liquid outlet pipe 8, which is respectively connected with the bottom of the disinfection chamber 16 and the bottom of the drying chamber 17. The liquid outlet pipe 8 is arranged in a tortuous manner, and a plurality of heat dissipation fins 81 are arranged on the liquid outlet pipe 8. An extraction pump 82 is arranged on the other end of the liquid outlet pipe 8. When the extraction pump 82 is started, the extraction pump 82 can condense and recycle the high-temperature disinfection steam in the disinfection chamber 16, recycle and reuse the condensed high-temperature disinfection steam in the disinfection chamber 16, and recycle and reuse the disinfection steam attached to the equipment in the drying chamber 17 and evaporated by drying, thereby improving the utilization rate of the disinfectant and fluorescein.

[0039] The implementation principle of an instrument sterilization transfer cabinet suitable for a biological clean environment in the embodiment of the present application is as follows: When the instrument needs to be disinfected: the instrument is placed on the first conveyor belt 2, the first conveyor belt 2 is started, and the instrument is transported into the disinfection chamber 16 by the first conveyor belt 2. The nozzle 162 in the disinfection chamber 16 sprays the disinfectant containing fluorescent substance, and the driving motor 611 is started. The starting motor drives the screw rod 612 to rotate. Since the screw rod 612 and the sliding block 613 are threadedly connected, the sliding block 613 can be driven to move. Since the gear ring 6143 and the rack 6145 are meshed with each other, When this sliding block 613 drives the multi-stage telescopic sleeve 6142 to move, the multi-stage telescopic sleeve 6142 can be rotated to start the electric telescopic rod 6141. Therefore, the extension of the telescopic end of the electric telescopic rod 6141 can drive the extension of the multi-stage telescopic sleeve 6142, thereby clamping the instrument. The instrument is clamped by the clamping block 6144 and the multi-stage telescopic sleeve 6142 is rotated by the gear ring 6143 and the rack 6145, so that the clamping and rotation disinfection of the instrument can be realized.

[0040] When the instrument needs to be dried: the instrument is transported to the second conveyor belt 3 by the first movable mechanism 6 or the second movable mechanism 7, and is then transported to the drying bin 17 by the second conveyor belt 3. The nozzle 162 in the drying bin 17 sprays high-temperature gas, and the operation during disinfection is repeated. The rotary clamping can centrifugally throw out the disinfectant accumulated inside the instrument, thereby improving the drying efficiency and drying effect when drying the instrument.

[0041] When it is necessary to detect the drying of the instrument: transport the instrument to the third conveyor belt 4 through the first moving mechanism 6 or the second moving mechanism 7, and the third conveyor belt 4 transports the instrument to the detection chamber 18, and repeat the disinfection or drying operation. If the light sensor 182 in the detection chamber 18 detects the presence of a fluorescent spot under the irradiation of the ultraviolet lamp 181 in the detection chamber 18, it means that the drying is incomplete or the cleaning is not thorough enough. Repeat the cleaning and drying until the fluorescent spot is no longer detected.
