It is a flowchart which shows an example of the operating method of the washing | cleaning apparatus of FIG. It is a figure which shows an example of the operating method of the washing | cleaning apparatus of FIG. 1, and has shown the relationship between the liquid temperature in a washing tank, and elapsed time.

Hereinafter, specific embodiments of the present invention will be described in detail with reference to the drawings.
The cleaning apparatus of the present invention is for cleaning an object to be cleaned, but may be an apparatus for rinsing an object to be cleaned instead of or in addition to cleaning. That is, the cleaning device can perform at least one of cleaning and rinsing of the object to be cleaned. Moreover, washing | cleaning and rinsing may each serve also as disinfection (decontamination).

FIG. 1 is a schematic view showing a main part of an embodiment of the cleaning apparatus of the present invention, and a part thereof is shown in cross section.
The cleaning apparatus 1 of the present embodiment includes a cleaning tank 3 in which liquid is stored and an object to be cleaned 2 is immersed, heating means 4 for heating the liquid in the cleaning tank 3, and gas in the cleaning tank 3. Depressurization means 5 that sucks and discharges to the outside and depressurizes the inside of the cleaning tank 3, liquid-phase air supply means 6 that introduces outside air to the liquid phase portion in the depressurized cleaning tank 3, and the decompressed cleaning tank 3 A gas-phase air supply means 7 for introducing outside air into the gas-phase portion, a pressure sensor 8 for detecting the pressure in the cleaning tank 3, a liquid temperature sensor 9 for detecting the temperature of the liquid stored in the cleaning tank 3, The control means 10 which controls each said means 4-7 based on the detection signal of each of these sensors 8 and 9 is provided. This control means 10 is also provided with a cleaning management function, and keeps the operation date and time, operation details, cleaning results, etc. as a history, and the contents can be confirmed as desired. A temperature sensor that detects the temperature of the gas phase portion in the cleaning tank 3 may be used instead of or in addition to the pressure sensor 8 that detects the pressure in the cleaning tank 3.

  The article to be cleaned 2 is an article to be cleaned or rinsed, for example, a medical instrument, an electronic component, or a mechanical component. The article to be cleaned 2 may be a tubular article such as a tube, an article having a bag hole, or a bottomed container.

  The cleaning tank 3 is a hollow container that can withstand the decompression of the internal space. The cleaning tank 3 includes a main body 11 that opens upward and has a hollow portion, and a door 12 that opens and closes the opening of the main body 11. When the door 12 is closed, the gap between the main body 11 and the door 12 is sealed with the packing 13.

  The cleaning tank 3 is supplied with liquid and stored. The type of the liquid is not particularly limited, and for example, water containing detergent, water not containing detergent, soft water, pure water, solvent, and the like.

  The heating means 4 warms the liquid stored in the cleaning tank 3. The heating means 4 is not particularly limited in its configuration, and may be, for example, a steam heater, but is an electric heater 14 in this embodiment. In this case, the liquid in the cleaning tank 3 can be heated by energizing the electric heater 14 with the liquid stored in the cleaning tank 3.

  The decompression means 5 decompresses the inside of the cleaning tank 3 by sucking and discharging the gas in the cleaning tank 3 to the outside. The decompression means 5 is not particularly limited in its configuration, but typically includes a heat exchanger for vapor condensation and a water ring vacuum pump.

  The liquid phase air supply means 6 introduces outside air into the liquid phase portion in the cleaning tank 3 whose pressure has been reduced through the liquid phase air supply path 15. The liquid phase air supply path 15 is provided with a filter 16 and a liquid phase air supply valve 17 in order toward the cleaning tank 3. Therefore, when the liquid-phase air supply valve 17 is opened in a state where the pressure in the cleaning tank 3 is reduced, air through the filter 16 is introduced into the stored liquid in the cleaning tank 3 due to the differential pressure inside and outside the cleaning tank 3. be able to.

  Air from the liquid phase air supply path 15 is introduced into the stored liquid in the cleaning tank 3 through a liquid phase air supply nozzle 18 provided at the bottom of the cleaning tank 3. The liquid-phase air supply nozzle 18 is a pipe disposed laterally at the bottom of the cleaning tank 3. The liquid phase air supply nozzle 18 is a bottom portion in the cleaning tank 3 but is separated from the bottom surface and is held horizontally. The liquid-phase air supply nozzle 18 is formed with nozzle holes 19 that open downward on the peripheral side wall of the pipe at set intervals along the pipe extending direction. Thereby, if the liquid phase air supply valve 17 is opened in a state where the inside of the cleaning tank 3 is depressurized, air can be uniformly introduced into the liquid stored in the cleaning tank 3.

  The gas-phase air supply means 7 introduces outside air to the gas phase portion in the depressurized cleaning tank 3 through the gas-phase air supply path 20. In the gas-phase air supply path 20, a filter 21 and a gas-phase air supply valve 22 are provided in order toward the cleaning tank 3. Therefore, when the gas-phase air supply valve 22 is opened in a state where the pressure in the cleaning tank 3 is reduced, air through the filter 21 is introduced into the cleaning tank 3 due to a differential pressure inside and outside the cleaning tank 3, and the cleaning tank 3 The pressure inside 3 can be restored. In addition, since the gas-phase air supply valve 22 is composed of an electromagnetic valve, the pressure in the cleaning tank 3 can be quickly restored.

  The control means 10 is a controller 23 that controls the means 4 to 7 based on the detection signals of the sensors 8 and 9 and the elapsed time. Specifically, the pressure sensor 8 and the liquid temperature sensor 9 are connected to the controller 23 in addition to the electric heater 14, the pressure reducing means 5, the liquid phase air supply valve 17, and the gas phase air supply valve 22. The controller 23 then cleans or rinses the article to be cleaned 2 in the cleaning tank 3 according to a predetermined procedure (program) as described below. The controller 23 is also a part of the cleaning management device, and keeps the operation date and time, operation details, cleaning results, etc. as a history, and allows the user to check the contents as desired.

FIG. 2 is a flowchart illustrating an example of an operation method of the cleaning apparatus 1 of the present embodiment.
Here, a process selected from among the pre-cleaning process S1, one or more cleaning processes S2 to S3, one or more rinsing processes S4 to S6, and a liquid draining process S7 is sequentially performed. More specifically, in the illustrated example, the pre-washing step S1, the first washing step S2, the second washing step S3, the first rinsing step S4, the second rinsing step S5, the third rinsing step S6, and the liquid draining step S7. Of these, the selected processes are executed sequentially. Before starting these steps, the object to be cleaned 2 is accommodated in the cleaning tank 3, and the door 12 of the cleaning tank 3 is closed in an airtight manner.

  The pre-cleaning step S1 and the cleaning steps S2 to S3 share common operations. Further, the cleaning steps S2 to S3 and the rinsing steps S4 to S6 are different in whether the liquid stored in the cleaning tank 3 is a cleaning liquid or a rinsing liquid, and common operations are possible. Furthermore, in the cleaning steps S2 to S3 and the rinsing steps S4 to S6, the temperature of the liquid in the cleaning tank 3 can be increased to disinfect the article 2 to be cleaned.

  In the pre-washing step S1, each washing step S2 to S3, and each rinsing step S4 to S6, among the liquid draining operation, the water supply operation, the liquid agent charging operation, the warming operation, the heat retaining operation, the cooling operation, the pressure recovery operation, and the draining operation, The selected operations are executed sequentially. In the liquid draining step S7, a liquid draining operation and a return pressure operation are performed. Hereinafter, each operation will be described in order.

  In the liquid draining operation, the inside of the cleaning tank 3 is decompressed by the decompression means 5, the liquid adhering to the object to be cleaned 2 is boiled and evaporated, and the liquid from the object to be cleaned 2 is drained. Thereafter, the pressure inside the cleaning tank 3 is restored by the gas-phase air supply means 7 with the decompression means 5 stopped. Note that the depressurization and the return pressure in the cleaning tank 3 may be repeated as desired. The liquid draining operation is performed when the liquid in the cleaning tank 3 is replaced, or when the object to be cleaned 2 is dried after cleaning or rinsing.

  In the water supply operation, water is supplied into the cleaning tank 3 by water supply means (not shown). When the water is supplied up to the set water level in the cleaning tank 3, the water supply operation is terminated. Further, in the liquid supply operation, the cleaning agent is supplied into the cleaning tank 3 by the liquid supply means (not shown) in the cleaning steps S2 and S3, and the rinsing agent is supplied into the cleaning tank 3 in the rinsing steps S4 to S6. .

  In the heating operation, the liquid in the cleaning tank 3 is heated by the heating means 4 until the liquid in the cleaning tank 3 reaches a set temperature.

  In the heat retaining operation, the liquid in the washing tub 3 is boiled or the pressure inside the washing tub 3 is depressurized until just before that. After the liquid is boiled, liquid phase air supply pulse control is repeated until the liquid in the cleaning tank 3 is reheated to the set temperature until a predetermined end condition is satisfied (Japanese Patent Application No. 2010-43688). Specifically, the liquid phase in the state where the liquid in the cleaning tank 3 is depressurized by the depressurizing means 5 until the liquid reaches a predetermined temperature (a temperature lower by 0.5 ° C. from the set temperature, for example), and the depressurization is stopped or continued. The return pressure by the air supply means 6 and the heating by the heating means 4 until the liquid temperature reaches the set temperature are repeated, for example, until a predetermined time elapses.

  According to the liquid phase air supply pulse control, the outside air is introduced into the liquid in the cleaning tank 3 from below the object to be cleaned 2 in a state where the liquid in the cleaning tank 3 is boiled or the pressure in the cleaning tank 3 is reduced to just before that. By introducing, the liquid in the cleaning tank 3 can be boiled explosively. As a result, the liquid in the cleaning tank 3 can be greatly swung to effectively clean or rinse the object to be cleaned 2.

  In the cooling operation, the pressure in the cleaning tank 3 is continuously reduced so that the liquid in the cleaning tank 3 continues to boil, and during this pressure reduction, outside air is introduced into the gas phase portion in the cleaning tank 3 and the boiling of the liquid stops. The gas-phase air supply pulse control is repeated until the predetermined termination condition is satisfied (Japanese Patent Application No. 2010-43687). More specifically, the pressure reducing means keeps boiling the liquid in the cleaning tank 3 until the liquid in the cleaning tank 3 reaches the end temperature, the pressure in the cleaning tank 3 reaches the end pressure, or a predetermined time elapses. The pressure in the cleaning tank 3 is continuously reduced by 5, and during this time, the gas-phase air supply means 7 repeats instantaneously temporarily returning the pressure in the cleaning tank 3 until boiling of the liquid stops at a predetermined timing. The predetermined timing is, for example, every time the liquid in the cleaning tank 3 decreases by a predetermined temperature or every time the pressure in the cleaning tank 3 decreases by a predetermined pressure.

  According to the gas-phase air supply pulse control, the liquid boiling is stopped at a stretch by instantaneously and temporarily restoring the pressure in the cleaning tank 3 while the liquid in the cleaning tank 3 is boiling. Therefore, every time the return pressure in the washing tank 3 is restored, the bubbles generated in the liquid by boiling until then are condensed instantly. The liquid is stirred and transferred by the pressure wave and pressure difference during the condensation, and the object to be cleaned 2 is cleaned or rinsed. In addition, when the object to be cleaned 2 is a tube or the object to be cleaned 2 has a bag hole, the vapor generated by boiling is accumulated in the tube or the bag hole, and when the pressure is restored, the vapor pool is erased at once The object to be cleaned 2 can also be cleaned or rinsed by vigorously putting the liquid into the tube or the bag hole.

  By the way, the predetermined temperature and the predetermined time in the liquid phase air supply pulse control, the end temperature (or the end pressure or the predetermined time) and the predetermined temperature (or the predetermined pressure) in the gas phase air supply pulse control are appropriately set. In each step S1 to S6, different numerical values can be used.

  In the return pressure operation, the inside of the cleaning tank 3 is returned to atmospheric pressure by the gas phase air supply means 7. In the draining operation, the liquid in the cleaning tank 3 is discharged by drain means (not shown).

  As described above, the cleaning device 1 of the present embodiment includes the pre-washing step S1, the first washing step S2, the second washing step S3, the first rinsing step S4, the second rinsing step S5, the third rinsing step S6, and the liquid draining step. Of S7, the selected processes are sequentially executed. For example, as shown in FIG. 3, by selecting a first cleaning step S2, a second cleaning step S3, a first rinsing step S4, and a second rinsing step S5, these selected steps are sequentially executed.

  Here, in the first cleaning step S2, the water supply operation a, the liquid agent charging operation, the warming operation b, the heat retaining operation c, the cooling operation d, and the pressure recovery operation are selected. In the second cleaning step S3, the heating operation e, the heat retaining operation f, the cooling operation g, the return pressure operation, and the draining operation h are selected. In the first rinsing step S4, the water supply operation i, the warming operation j, the heat retaining operation k, the cooling operation l, the return pressure operation, and the drainage operation m are selected. Further, in the second rinsing step S5, the water supply operation n, the liquid agent charging operation, the warming operation o, the heat retaining operation p, the cooling operation q, the return pressure operation, and the drainage operation r are selected.

  However, this operation method is merely an example, and needless to say, it can be changed as appropriate. That is, which process is selected and executed from each of the cleaning processes S2 to S3 and each of the rinsing processes S4 to S6, and which operation is selected and executed in the selected process, and the selection thereof. The content (for example, temperature, pressure, time, etc.) of the performed operation can be changed as appropriate.

  Now, the cleaning device 1 is configured and operated as described above, but the operation date and time, operation details, cleaning results, etc. operated in this way are left as a history, and the contents can be confirmed as desired.

  First, referring again to FIG. 1, the cleaning device 1 includes an operation panel 24, and the operation panel 24 includes various operation buttons 26 as desired in addition to the touch screen 25. Based on the settings and operations on the operation panel 24, the controller 23 operates the cleaning apparatus 1 as described above and executes cleaning management as described below. For this purpose, the touch screen 25 and the operation buttons 26 are connected to the controller 23.

  The touch screen 25 is configured by arranging a touch panel on the surface of the liquid crystal display. The touch screen 25 performs various types of display on the display, and when the display button is pressed, the touch panel 25 detects it and enables various settings or operations while appropriately changing the screen display.

  Data on the display screen of the touch screen 25, an operation program for the cleaning device 1, and the like are stored in the information storage unit 27. The information storage unit 27 also functions as a driving information storage unit 28 for storing driving information. However, a portable storage medium (for example, an SD card) can be attached to and detached from the operation panel 24, and the operation information in the operation information storage unit 28 can be copied to this portable storage medium so that it can be used in other devices. . In some cases, the portable storage medium itself may be used as the operation information storage unit 28 to directly store the operation information in the portable storage medium.

  Further, another device (for example, a personal computer or a sterilization management device) may be connected to the operation panel 24 so that the operation information can be read and viewed and managed by the other device. For example, if the cleaning device 1 is connected to a sterilization management device, or the cleaning device 1 and the sterilization device are connected to a common personal computer, the article to be sterilized after cleaning is cleaned and sterilized under any conditions. It is possible to unify and manage the results of cleaning and sterilization.

  Prior to the start of operation, the object to be cleaned 2 is accommodated in the cleaning tank 3, and preferably a cleaning indicator is also placed. Prior to the start of operation, various settings are made using the operation panel 24. As described above, this setting includes selection of an execution process, selection of an execution operation in each selected process, and settings such as temperature and time during each of the selected operations.

  After performing various settings in this way, the operation panel 24 is operated to instruct the start of operation. As a result, the selected process and operation are performed. For example, the process and operation of FIG. 3 described above are performed.

  The controller 23 stores driving information in the driving information storage unit 28 for each driving. Although it can change suitably as driving | operation information, the following information is contained in a present Example. In addition, since these information is memorize | stored for every driving | running, about each driving | operation, the specific identification information (for example, serial number) is attached | subjected for every driving | operation, (a) Each item below is matched with the driving | operation identification information. Is memorized. As this driving identification information, (a) driving date and time can also be used. In that case, (b) the following items are stored corresponding to (a) driving date and time.

  Hereinafter, each information will be briefly described.

  (A) The operation date and time is the date and time when the operation of the cleaning apparatus 1 is started, and is information such as “April 14, 2010, 13:27”. When the operation is started based on the operation of the operation panel 24 by the user, the controller 23 stores information on the operation start date and time in the operation information storage unit 28.

  (B) The result of the cleaning indicator is a determination result of the cleaning indicator, and is, for example, information of “◯ (good)” or “× (bad)”. When the operation ends, the result of the cleaning indicator is input by the user based on the operation of the operation panel 24, and the controller 23 stores the information in the operation information storage unit 28.

  (C) The set temperature in the first cleaning step S2 is the target temperature T1 in the heating operation b in the first cleaning step S2, and is set to, for example, “50 ° C.”. The set temperature is set from the operation panel 24 by the user prior to the start of operation.

  (D) The number of liquid phase air supply pulses in the first cleaning step S2 is the number of air supply times to the liquid phase part executed in the liquid phase air supply pulse control of the heat retaining operation c in the first cleaning step S2. 8 times ". Prior to the start of operation, as a condition for ending the liquid phase air supply pulse control, elapse of a predetermined time (for example, 15 minutes) is set, but the number of liquid phase air supply pulses may be set depending on circumstances. In the former case, the controller 23 counts the number of liquid-phase supply pulses during operation and stores the number of times. In the latter case, the number of liquid-phase supply pulses is set by the user on the operation panel 24 prior to the start of operation. Set from

  (E) The number of gas phase air supply pulses in the first cleaning step S2 is the number of air supply times to the gas phase section executed in the gas phase air supply pulse control of the cooling operation d in the first cleaning step S2. 3 times ". Prior to the start of operation, the end condition of the gas-phase air supply pulse control is usually set by the temperature of the stored liquid, the pressure in the cleaning tank 3, or the time. Therefore, the controller 23 counts the number of gas-phase air supply pulses during operation and stores the number of times.

  (F) The set temperature in the second cleaning step S3 is the target temperature T2 in the heating operation e of the second cleaning step S3, and is set to “93 ° C.”, for example. The set temperature is set from the operation panel 24 by the user prior to the start of operation.

  (G) The number of liquid phase air supply pulses in the second cleaning step S3 is the number of times of air supply to the liquid phase part executed in the liquid phase air supply pulse control of the heat retaining operation f in the second cleaning step S3. 6 times ". Prior to the start of operation, as a condition for ending the liquid phase supply pulse control, elapse of a predetermined time (for example, 10 minutes) is set, but the number of times of the liquid phase supply pulse may be set depending on circumstances. In the former case, the controller 23 counts the number of liquid-phase supply pulses during operation and stores the number of times. In the latter case, the number of liquid-phase supply pulses is set by the user on the operation panel 24 prior to the start of operation. Set from

  (H) The disinfection setting time in the second cleaning step S3 is an execution time of the heat retaining operation f in the second cleaning step S3, and is, for example, “10 minutes”. In addition, this disinfection setting time is normally set from the operation panel 24 by the user prior to the start of operation.

  (I) The A0 value at the time of disinfection in the second cleaning step S3 is a value indicating the disinfection effect. Specifically, the A0 value is calculated by the following formula, and t seconds with respect to the heating time (seconds) at 80 ° C. It is the value showing the amount of heat sterilization (power). The A0 value is set to “6000”, for example. The controller 23 calculates and stores the A0 value using the detection signal of the liquid temperature sensor 9 in the heat retaining operation f of the second cleaning step S3. Prior to the start of operation, the A0 value may be set by the user. In this case, the heat retaining operation f in the second cleaning step S3 may be executed until the set A0 value is reached.

  (J) The number of gas-phase air supply pulses in the second cleaning step S3 is the number of air-phase supply times performed in the gas-phase air supply pulse control of the cooling operation g in the second cleaning step S3. 3 times ". Prior to the start of operation, the end condition of the gas-phase air supply pulse control is usually set by the temperature of the stored liquid, the pressure in the cleaning tank 3, or the time. Therefore, the controller 23 counts the number of gas-phase air supply pulses during operation and stores the number of times.

  (K) The operation time is the time required for the operation, more specifically, the required time from the start of the operation to the end of the operation, for example, “120 minutes”.

  (L) The supply history of the cleaning liquid and the presence / absence of the input abnormality are information indicating whether or not the cleaning agent or the rinsing agent has been normally input, and are stored as, for example, “◯ (normal)” or “× (abnormal)”. . The liquid supply means into the cleaning tank 3 is configured by connecting the liquid tank and the cleaning tank 3 via a liquid supply valve, and the liquid supply operation in each step is performed while the pressure in the cleaning tank 3 is reduced. When the valve is opened, the pressure in the cleaning tank 3 is monitored during the supply of the liquid agent into the cleaning tank 3, and the liquid agent in the liquid agent tank is emptied if there is a sudden pressure increase. For this reason, it can be understood that the outside air has been introduced into the cleaning tank 3. In that case, a history is left as an abnormality. In the case where a charging abnormality has occurred, it is preferable that the cleaning device 1 informs that effect at that time and stops the operation.

  (M) The cleaning liquid temperature data is obtained by storing the temperature detected by the liquid temperature sensor 9 from the start of operation to the end of operation, for example, in units of 1 second.

  (N) The washing tank pressure data is obtained by storing the pressure detected by the pressure sensor 8 from the start of operation to the end of operation, for example, in units of 1 second.

  (O) Test records include test operation data, leak test results, and the like. The trial run is a record of the trial run performed when the cleaning device 1 is delivered to the user. In addition, the leak test is a test for confirming the airtightness inside and outside the cleaning tank 3 based on whether or not the pressure is restored to a predetermined level or more when the inside of the cleaning tank 3 is depressurized to a certain pressure and left for a certain time. For example, when the gas phase supply valve (solenoid valve) 22 is replaced, a leak test is performed.

  All of the items (a) to (o) are preferably collected and stored. However, some items may be deleted or other items may be added. Further, as described above, it is sufficient to store the set temperature of the heat retaining operation, the number of liquid-phase air supply pulses, and the number of gas-phase air supply pulses, as described above. However, if necessary, the rinsing steps S4-S6 are also stored. Similar information may be stored.

  Now, the driving information for each driving stored in the driving information storage unit 28 can be viewed on the touch screen 25 of the operation panel 24 as desired. For example, when the “view driving information (for user)” button on the menu screen on the touch screen 25 is pressed, an operation list screen is displayed, and a desired operation may be selected. Specifically, on the operation list screen, for example, only the operation date / time is displayed in a time-series table format for the past operation, and a desired operation date / time button may be selected by pressing it.

  For the operation selected in this way, the controller 23 acquires the operation information about the operation from the operation information storage unit 28 based on the operation identification information (for example, operation date and time). o) Display some or all of the items. For example, (a) the operation date and time, (b) the result of the cleaning indicator, (i) the A0 value at the time of disinfection, (k) only the operation time is displayed.

  On the other hand, even if the “View driving information (for maintenance)” button on the menu screen is pressed, the driving information can be displayed in the same manner as described above. In this case, all items (a) to (o) can be viewed. It is said. However, addition and deletion of display items can be changed as appropriate for both display screens of the user and maintenance personnel. Note that (m) cleaning liquid temperature data and (n) cleaning tank pressure data are preferably displayed as graphs.

  Thus, according to the cleaning apparatus 1 of the present embodiment, the cleaning date and time, cleaning conditions, cleaning results, disinfection (decontamination) results, etc. can be stored in the apparatus, and the cleaning history can be managed.

  That is, the cleaning device manages the result of the cleaning indicator as the operation information in addition to the operation date and time, the A0 value, and the operation time. In addition, a cleaning apparatus that performs a process including liquid phase air supply pulse control and gas phase air supply pulse control in order one or more times after heating the liquid in the cleaning tank to a set temperature, For at least one process, the set temperature, the number of liquid phase supply pulses, and the number of gas phase supply pulses are managed. In particular, in liquid phase air supply pulse control that also serves as a disinfection and immediately after gas phase air supply pulse control, in addition to set temperature, liquid phase air supply pulse number, gas phase air supply pulse number, liquid phase air supply pulse control It is preferable to manage the disinfection setting time as the execution time and the A0 value by the execution of the liquid-phase air supply pulse control.

  The cleaning effect can be confirmed by managing the A0 value. In addition, by managing the operation time as the time required from the start of operation to the end of operation rather than the time of operation start and operation end, you can directly know the length of the operation time, wear parts, etc. Easy to grasp. For example, if the operation content is the same, but the operation time is longer than usual, it is possible to suspect the consumption of components (for example, a solenoid valve for supplying air) for maintaining the airtightness in the cleaning tank 3.

  Furthermore, as described above, by dividing the operation date and time, the result of the cleaning indicator, the A0 value at the time of disinfection, the operation time output, and the output of other items, it is divided into user browsing and maintenance personnel browsing. be able to. Since the information required by the user is whether or not cleaning or disinfection has been performed for an operation on a certain day, the output can be easily understood by the user by separating it from the output of other detailed information.

  The cleaning device 1 of the present invention is not limited to the configuration of the above embodiment, and can be changed as appropriate. In particular, the specific cleaning method for the object to be cleaned 2 is not limited to the above-described embodiment, and can be similarly applied to other cleaning apparatuses 1 such as an ultrasonic cleaning apparatus.

  Needless to say, the types of items managed as operation information can be added or deleted as appropriate. For example, it is good also as a structure which does not manage the result of a washing | cleaning indicator, In that case, the user can browse an operation date, A0 value at the time of disinfection, and an operation time.
