Description

  The invention described in the claims of the present application relates to a sterilization apparatus that sterilizes a specific space by ejecting a mist or vaporized disinfectant into the specific space to be sterilized.

  With the rapid increase in population on the earth, the further activation and speedup of various human activities and exchanges resulting from this, and the expansion of the range of human activities, the spread of bacteria and viruses to humans There is an increased risk of infection. In particular, the increased risk of human infection with highly pathogenic viruses is a pandemic where highly pathogenic viruses repeatedly infect humans in a short period of time and the infected person spreads around the world ( There is a possibility that it may lead to the occurrence of an infection explosion), and an appropriate measure against it is desired. In a pandemic, there is a fear that once an outbreak occurs, a large number of infected people will appear simultaneously in the world.

  To prevent a pandemic, it is most important to try to block the virus infection route. Virus infection routes can be broadly classified into contact infection routes, droplet infection routes, and air infection routes. Of these, the contact infection route can be blocked by carefully avoiding contact with the source of infection, and is not extremely difficult to block for ordinary people except medical personnel. However, with regard to the splash infection route and the air infection route, a specific space (disinfection space) to be sterilized is provided so that the sterilization space is always sterilized, and each person is blocked using such sterilization space. It is necessary to strive for.

  In order to disinfect the sterilization space, it is necessary to suspend the disinfectant in the sterilization space. And as a method of making the disinfectant float in the disinfection space, for example, a vaporization type, a vapor type and a mist type can be mentioned.

  In the vaporization method, the liquid or gel-like disinfectant is evaporated at room temperature to generate a disinfectant gas that is a vaporized disinfectant, and the disinfectant gas is released into the disinfecting space. To do. In the vapor method, the liquid or gel-like disinfectant is heated and evaporated to generate a disinfectant gas that is a vaporized disinfectant, and the disinfectant gas is released into the disinfecting space. To do. Furthermore, in the mist method, the liquid disinfectant is made into fine particles at room temperature to generate a disinfectant mist that is a disinfectant that has been converted into a mist. To release. The conventional apparatus related to these methods is summarized as follows, regardless of the size of the disinfection space volume.

  First, as a conventional apparatus employing a vaporization method, a sterilization apparatus using a sterilizing alcohol liquid as a volatile component as a liquid disinfectant (see, for example, Patent Document 1), and stored in a cartridge cylinder as a liquid disinfectant Sterilizer using sterilized liquefied ethylene oxide gas (EOG) (for example, see Patent Document 2), chlorine dioxide gas generator using sterilizing chlorine dioxide solution stored in a tank as a liquid disinfectant (for example, patent Document 3) has been proposed. By applying the technical idea found in the conventional apparatus described in each of Patent Documents 1 to 3, the disinfection space provided for blocking the droplet infection route or the air infection route as described above It is thought that disinfectant can be suspended.

  In addition, as a conventional apparatus using a steam method, sterilization using gel-like sterilizing chlorine dioxide contained in a container as a gel-like disinfectant and directly heating it to generate sterilizing chlorine dioxide gas A deodorizing device (see, for example, Patent Document 4) has been proposed. Even if the technical idea found in the conventional apparatus described in Patent Document 4 is applied, a disinfectant agent is placed in the disinfecting space provided for blocking the above-described droplet infection route or air infection route. It is considered possible to float.

  Furthermore, as a conventional device using a mist type method, water or a solution of antibacterial agent, antifungal agent, deodorant and the like is made to mist by vibrating with an ultrasonic oscillator, and the solution mist is jetted outside. A spraying device (see, for example, Patent Document 5) has been proposed. According to the conventional apparatus described in Patent Document 5, a solution mist having a particle size of approximately 0.1 microns or less can be sprayed into a predetermined space such as a room. The solution mist can be retained for a relatively long time. Even if the technical idea found in the conventional apparatus described in Patent Document 5 is applied, disinfectant is not contained in the disinfecting space provided for blocking the above-described droplet infection route or air infection route. It is considered possible to float.

  When disinfecting the disinfecting space by suspending the disinfecting agent in the disinfecting space, the concentration of the disinfecting agent gas or the disinfecting agent mist in the disinfecting space is set to a preset maximum concentration that is greater than or equal to the preset minimum concentration, for example. Controls are required to maintain the appropriate values below for a predetermined time. Only when such a requirement is satisfied, the disinfection action in the disinfection space becomes effective.

  However, a conventional apparatus that employs a vaporization method as described in Patent Documents 1 to 3 above, or a conventional apparatus that employs a vapor method as described in Patent Document 4 above. When applying the technical idea found in the apparatus and floating the disinfectant in the disinfecting space (hereinafter referred to as the case of the first prior art application example), the disinfecting agent gas once released in the disinfecting space is It takes a relatively long time to change its state, and it cannot be controlled to change its concentration quickly and to maintain an appropriate preset value over a predetermined time. There is an inconvenience. For example, in the case of a disinfecting space where people come and go, the concentration of the disinfectant chemical gas required there changes greatly with the person going in and out and the passage of time. In the case of the first prior art application example Cannot accurately cope with the large change required for the concentration of the disinfectant gas in the disinfection space. In such a case, the concentration of the disinfectant gas in the disinfecting space may be increased more than necessary in advance, and it may be possible to deal with leakage of the disinfecting agent gas outside the disinfecting space. There is a possibility that a high concentration of disinfectant chemical gas may adversely affect people in the disinfection space.

  Furthermore, in the case of the first prior art application example, when the sterilization space is a space having a large volume formed on a large floor under a high ceiling, for example, the sterilization chemical gas is located above the sterilization space. The concentration of the disinfectant chemical gas near the floor will decrease significantly, or it will take a very long time to increase the concentration of the disinfectant chemical gas near the floor, disinfecting people on the floor. There arises a disadvantage that the action cannot be effectively obtained, or that a very long time is required until the disinfection action reaches the person on the floor. Under such circumstances, the sterilization effect in the sterilization space cannot be accurately confirmed, and therefore, it is difficult to make a supply plan for the sterilization agent.

  In addition, in the case where a disinfectant is suspended in a disinfection space by applying a technical idea found in a conventional apparatus that employs a mist type method as described in Patent Document 5 described above (hereinafter referred to as second prior art). In order to make the disinfection action effective in the disinfection space, a continuous or intermittent jet of disinfectant mist for a relatively long time is applied to the disinfection space. Such a disinfectant mist is continuously or intermittently ejected over a relatively long period of time, for example, by periodically ejecting a certain amount of disinfectant mist, At that time, evaluation of the concentration of the disinfectant drug mist in the disinfection space and control of the concentration based on the evaluation are not performed.

  Thus, even in the case of the second prior art application example, the concentration of the disinfectant drug mist in the disinfection space is appropriately evaluated, and the concentration is set to an appropriate value set in advance for a predetermined time. There is an inconvenience that it is not possible to control to maintain.

  In view of such a point, the invention described in the claims of the present application ejects a disinfectant chemical mist or a disinfectant drug gas into the disinfecting space and floats the disinfecting agent in the disinfecting space. In performing disinfection, the ejection of the disinfectant mist or disinfectant gas into the disinfecting space is accurately controlled based on an appropriate calculation, so that the concentration of the disinfectant agent mist or disinfectant gas in the disinfecting space is controlled in advance.

For example, a control on signal for turning on the power supply unit 33 and starting a control operation by the operation control unit 25, In addition, the power supply unit 33 is turned off, and a control off signal for terminating the control operation by the operation control unit 25 is supplied to the operation control unit 25. The supply of the control ON signal or the control OFF signal to the operation control unit 25 is performed by, for example, operating the input operation unit 28 manually or by other means. The operation control unit 25 supplies the control signal CP to the power supply unit 33 in response to the control on signal or control off signal from the input operation unit 28, and causes the power supply unit 33 to be in the on state or the off state.

  In the disinfectant supply unit 21, for example, a disinfectant stock solution storage unit 41 that stores a disinfectant stock solution that is a stabilized chlorine dioxide solution and the like, and a water / activator that stores water or an activator for the disinfectant stock solution A housing portion 42 is provided. The disinfectant stock solution stored in the disinfectant stock solution storage unit 41 and the water or activator stored in the water / activator storage unit 42 are appropriately replenished as necessary by means not shown.

  Under the condition that the power supply unit 33 is turned on, the disinfectant stock solution stored in the disinfectant stock solution storage unit 41 and the water or the activator stored in the water / activator storage unit 42 are supplied from the operation control unit 25. Derived from the disinfectant stock solution container 41 and the water / activator container 42 by the derivation unit 43 that operates in response to the control signal CA, and is temporarily stored in the temporary container 44 and the primary container 45. The temporary storage unit 44 includes a remaining amount sensor 44 a that detects the remaining amount of the disinfectant stock solution temporarily stored, and the remaining amount sensor 44 a supplies a detection output signal DD to the operation control unit 25. . Similarly, the temporary storage unit 45 is also provided with a remaining amount sensor 45a for detecting the remaining amount of temporarily stored water or activator, and the remaining amount sensor 45a controls the operation of the detection output signal DW. To the unit 25. Based on the detection output signal DD and the detection output signal DW, the operation control unit 25 supplies the control signal CA to the deriving unit 43 and activates the deriving unit 43 as necessary. Replenishment or replenishment of water or activator in the temporary storage unit 45 is performed. Note that the derivation unit 43 is not necessarily provided as an independent device, and is not provided, and the temporary storage unit 44 and the temporary storage unit 45 are provided in the disinfectant stock solution storage unit 41 and the water / activator storage unit 42. May be directly linked.

  The disinfectant stock solution temporarily stored in the temporary storage unit 44 and the water or activator temporarily stored in the temporary storage unit 45 operate in response to a control signal CB from the operation control unit 25. Are respectively derived from the temporary storage unit 44 and the temporary storage unit 45 and supplied to the mixing unit 47. The mixing unit 47 operates in response to the control signal CM from the operation control unit 25, mixes the disinfectant stock solution supplied through the derivation unit 46 with water or an activator, and forms an aqueous solution or gel-like disinfectant. Is generated and sent to the temporary storage 48. Thereby, the temporary storage unit 48 temporarily stores the aqueous or gel-like disinfectant. The aqueous solution or gel-like disinfectant temporarily stored in the temporary storage unit 48 in this manner is used as the disinfectant stored in the disinfectant supply unit 21 so as to be supplied.

  The aqueous solution or gel-like disinfectant temporarily stored in the temporary storage unit 48 in the disinfectant supply unit 21 is temporarily stored in the temporary storage unit 48 by the drug derivation unit 22 that operates according to the control signal CX from the operation control unit 25. Is supplied to the mist / vaporizer 49 provided in the output unit 23. The mist / vaporization unit 49 operates in response to a control signal CY from the operation control unit 25, and performs a mist process or a vaporization process on the aqueous solution or gel-type disinfectant supplied through the drug derivation unit 22. At that time, when an aqueous disinfectant is supplied, the mist / vaporizer 49 performs a mist process on the aqueous disinfectant to generate a disinfectant mist. When a disinfectant is supplied, the gel-like disinfectant is vaporized to generate a disinfectant gas.

  The output unit 23 is also provided with a sending unit 50. The sending unit 50 operates in response to the control signal CZ from the operation control unit 25, and the disinfecting agent mist or disinfecting agent generated by the mist / vaporizing unit 49. The gas is sent to the ejection part 24. The ejection unit 24 ejects the disinfecting chemical mist or the disinfecting chemical gas sent from the output unit 23 according to the control signal CZ into the disinfecting space 12. As a result, a state in which the disinfectant is suspended in the disinfecting space 12 is obtained.

  The operation control unit 25 is configured by using a computer such as a microcomputer, and operates according to a control program read from the ROM 31. As described above, the ejection unit 24 ejects the disinfecting agent mist or disinfecting agent gas into the disinfecting space 12, whereby the disinfecting agent is floated in the disinfecting space 12 and the disinfecting space 12 is disinfected. In operation, the operation control unit 25 performs control for maintaining the concentration of the disinfectant drug mist or the disinfectant agent gas in the disinfecting space 12 at a value not less than a preset minimum concentration and not more than a preset maximum concentration. The control performed by the operation control unit 25 is performed by, for example, a medicine ejection calculation for setting the ejection time when the disinfection medicine mist or the disinfection medicine gas should be ejected by the ejection unit 24 by the calculation means included in the operation control unit 25. When the control operation signal for turning on the power supply unit 33 is supplied from the input operation unit 28 to the operation control unit 25, for example, the power supply unit 33 is turned off from the input operation unit 28 to the operation control unit 25. It repeats over a predetermined time until the control off signal to be put into the state is supplied, and according to the result of the medicine ejection calculation, the mist / vaporization section 49 and the medicine derivation section 22 and the output section 23 By controlling the operation with the delivery unit 50, the ejection unit 24 ejects the disinfectant drug mist or the disinfectant drug gas at each ejection time set by the medicine ejection calculation. It is to obtain a state.

  In such a case, the operation control for controlling the operation of the mist / vaporization unit 49 and the delivery unit 50 in the drug derivation unit 22 and the output unit 23 according to the result of the drug ejection calculation is a control included in the operation control unit 25. The signal sending means generates a control signal CX, a control signal CY, and a control signal CZ corresponding to the ejection timing set by the medicine ejection calculation, and these are the mist / vaporization section 49 in the medicine derivation section 22 and the output section 23. And are sent to the sending unit 50 in the output unit 23, respectively.

  The above-described medicine ejection calculation by the calculation means included in the operation control unit 25 is performed as follows while data is exchanged between the calculation means and the RAM 32. First, at the start of the medicine ejection calculation, initial concentration estimation setting for estimating and setting the initial concentration of the disinfectant drug mist or the disinfectant drug gas in the disinfection space 12 is performed. The initial density estimated and set by the initial density estimation setting is not less than the preset minimum density and not more than the preset maximum density.

  In this initial concentration estimation setting, the previous concentration which is the concentration obtained from the calculation result of the previous medicine ejection calculation recorded in the output information recording means included in the operation control unit 25, the communication unit 27 communicates with the remote server 36. The concentration obtained from the remote server 36 obtained by performing the operation and supplied to the operation control unit 25, for example, on the basis of information related to the ejection of the disinfectant drug mist or the disinfectant drug gas into the disinfecting space 12 by the nearby disinfecting device 35 The external input density or the manual input density that is input to the operation control unit 25 when the input operation unit 28 is operated is used as appropriate. For example, if there is a previous concentration, the previous concentration is used, and if there is no previous concentration and communication between the communication unit 27 and the remote server 36 is possible, the external input concentration is used, and the previous concentration is used. If there is no communication and communication between the communication unit 27 and the remote server 36 is impossible, the manually input concentration is used and the initial concentration is estimated and set.

  Thereafter, a sensor output that is corrected according to the sensor output supplied from the various sensors 26 to the operation control unit 25 is added to the initial concentration of the disinfecting agent mist or the disinfecting agent gas in the disinfecting space 12 obtained by the initial concentration estimation setting. Density correction according to the above is performed to obtain a corrected density. However, under the situation where the sensor output from the various sensors 26 is not supplied to the operation control unit 25, the density correction according to the sensor output is not performed, and the initial density is directly used as the corrected density.

  Subsequently, the correction density and the reference standard density are compared. The reference standard concentration is, for example, the disinfectant drug mist in the standard space represented by the standard space information included in the information from the remote server 36 obtained by the communication unit 27 communicating with the remote server 36 and supplied to the operation control unit 25. Alternatively, the concentration is set as the concentration of the disinfecting chemical gas, and is set to be equal to or higher than the preset minimum concentration and equal to or lower than the preset maximum concentration. When the communication unit 27 cannot communicate with the remote server 36 or when the communication unit 27 is not provided, the reference standard concentration is previously stored in the operation control unit 25 through the input operation unit 28. It is set by being supplied or set or by being included in a control program stored in the ROM 31 in advance. Also in such a case, the reference standard density is set to be equal to or higher than the preset minimum density and equal to or lower than the preset maximum density.

  The reference space is a space equivalent to the sterilization space 12, and is a virtual ideal space in which the concentration of the sterilization chemical mist or the sterilization chemical gas taking an appropriate value therein is preset as a reference standard concentration. The ideal space here means, for example, that the concentration of the disinfectant mist or disinfectant gas is constant within an extremely short time, and the constant concentration is maintained for a relatively long time, for example, about 20 minutes. It is a closed space where no people or objects exist and the air pressure is kept constant in a no wind condition. The remote server 36 stores various types of information regarding the standard space including the reference standard density as standard space information.

  The reference space information stored in the remote server 36 is, for example, “in the reference space, a chlorine dioxide mist or chlorine dioxide gas with a concentration of 1 ppm is blown out by rotating a fan with a diameter of 12 cm for 10 minutes at 1200 rpm. By doing this, after proper sterilization has been performed, the fan with a diameter of 12 cm is intermittently operated every 5 minutes with its rotation speed reduced to 600 rpm. The information is such that “a proper disinfection state can be maintained”.

  Such reference space information is sent from the remote server 36 to the operation control unit 25 through the communication unit 27 communicating with the remote server 36 and stored in the RAM 32 connected to the operation control unit 25.

  As a result of the comparison between the corrected concentration and the reference standard concentration, if the corrected concentration does not reach the reference standard concentration, it is determined that the concentration of the disinfectant chemical mist or the disinfectant chemical gas in the disinfecting space 12 is in a reduced state. In order to increase the concentration, an ejection time for causing the ejection section 24 to eject the disinfectant chemical mist or the disinfectant chemical gas is set, and the correction concentration is increased by a very small constant value, for example. On the other hand, as a result of the comparison between the corrected concentration and the reference standard concentration, if the corrected concentration is equal to or higher than the reference standard concentration, it is determined that the concentration of the disinfectant chemical mist or the disinfectant chemical gas in the disinfecting space 12 is in an increased state, In order to reduce the concentration, the correction concentration is reduced by, for example, a very small constant value without setting the ejection time for causing the ejection unit 24 to eject the disinfectant chemical mist or the disinfectant chemical gas.

  Then, for example, it is determined whether or not an end signal formed in the operation control unit 25 has arrived at the computing means in response to a control off signal for turning off the power supply unit 33, and an end signal has arrived. In this case, the calculation operation by the calculation means is stopped. On the other hand, when the end signal has not arrived, the first medicine ejection calculation is terminated, and the second medicine ejection computation is immediately started. In the second medicine ejection calculation, the corrected concentration that is increased or decreased by a very small constant value by the first medicine ejection calculation is set as the initial post-concentration, and the first medicine ejection is related thereto. Similar to the density correction according to the sensor output added to the initial density in the calculation, the density correction according to the sensor output is performed to obtain the corrected density, and then the correction density is compared with the reference standard density. In accordance with the result, an ejection time for causing the ejection unit 24 to eject the disinfectant chemical mist or the disinfectant chemical gas is set, and the correction concentration is increased by a very small constant value, for example. Alternatively, the correction concentration is, for example, extremely small without setting the ejection time for causing the ejection unit 24 to eject the disinfectant chemical mist or the disinfectant chemical gas. Used to lower the only value.

  Thereafter, for example, it is determined whether or not an end signal formed in the operation control unit 25 has arrived at the calculation means in response to a control off signal for turning off the power supply unit 33, and an end signal has arrived. In this case, the calculation operation by the calculation means is stopped. On the other hand, when the end signal has not arrived, the second medicine ejection calculation is terminated, and immediately, the third medicine ejection computation is started continuously in the same manner as the second medicine ejection computation.

In this way, the medicine ejection calculation by the calculating means in the operation control unit 25 is controlled by the input operation unit 28 from the input operation unit 28 to the operation control unit 25, for example, from the time when the control ON signal is supplied from the input operation unit 28 to the operation control unit 25. This process is repeated for a predetermined time until the time when the OFF signal is supplied. And the output information recording means contained in the operation | movement control part 25 records the result of these chemical | medical agent ejection calculations as output information.

  Further, at this time, the operation control unit 25 controls the control signal sending means included in the control signal sending means for each ejection timing set by the medicine ejection calculation repeatedly performed over a predetermined time by the calculation means as described above. The signal CX, the control signal CY, and the control signal CZ are formed and sent to the medicine derivation unit 22, the mist / vaporization unit 49 in the output unit 23, and the delivery unit 50 in the output unit 23, respectively. 22, the mist / vaporizer 49 in the output unit 23 and the delivery unit 50 in the output unit 23 are operated, and for example, a certain amount of a disinfectant mist or disinfectant gas, which is extremely small, is supplied to the ejection unit 24. , It is sent for a certain period of time, which is extremely short. Thereby, for each ejection time set by the medicine ejection calculation performed by the computing means, for example, a certain amount of the disinfectant medicine mist or the disinfectant medicine gas, which is made extremely small, is made extremely short, for example. For a certain period of time.

  As described above, a fixed amount of disinfectant mist or disinfectant gas, for example, a very small amount, for example, is extremely short from the ejection unit 24 at each ejection time set by the medicine ejection computation performed by the computing means. By being ejected into the sterilization space 12 for a certain period of time, the concentration of the sterilization chemical mist or the sterilization chemical gas in the sterilization space 12 is at least controlled from the input operation unit 28 to the operation control unit 25, for example. The maximum density set in advance over the preset minimum density over a predetermined time from the time when the signal is supplied to the time when the control off signal is supplied from the input operation unit 28 to the operation control unit 25. Maintained below. As a result, the sterilization space 12 is properly sterilized with the disinfecting agent floating there.

  The output information recorded in the output information recording means included in the operation control unit 25 is supplied to the communication unit 27 by the operation control unit 25, and the communication unit 27 transmits the output information to the remote server 36 and transmits it to the remote server 36. Shall be recorded in

  The output information recorded in the output information recording means included in the operation control unit 25 is also supplied to the display unit 30 by the operation control unit 25, and the display unit 30 is sterilized by the ejection unit 24 based on the output information. A display indicating the state of ejection of the disinfectant drug mist or disinfectant gas into the space 12 is performed.

  The communication unit 27 also communicates with a neighboring disinfecting device 35 to obtain neighboring information related to the ejection of the disinfecting chemical mist or the disinfecting chemical gas into the disinfecting space 12 by the neighboring disinfecting device 35, and the operation control unit 25 To supply. Then, the calculation means in the operation control unit 25, if necessary, performs the drug ejection calculation to set the ejection time for causing the ejection unit 24 to eject the disinfectant drug mist or the disinfectant drug gas. Use neighborhood information from 35. When neighboring information is used in the medicine ejection calculation to set the ejection time for causing the ejection section 24 to eject the disinfectant medicine mist or the disinfection medicine gas, the disinfection medicine mist or the disinfection medicine gas by the ejection section 24 is used. The ejection can be coordinated with the timing of ejection of the disinfectant drug mist or disinfectant drug gas into the disinfecting space 12 by the nearby disinfecting device 35, and the disinfecting action on the disinfecting space 12 is more effective. It is supposed to be.

  FIG. 2 shows a control program executed by the microcomputer constituting the operation control unit 25 in disinfecting the sterilization space 12 as described above when the operation control unit 25 is configured using a microcomputer as described above. It is a flowchart which shows an example.

  Under the control program executed in accordance with the flowchart shown in FIG. 1, the time when the control-on signal is supplied from the input operation unit 28 to the operation control unit 25 is set as the start time. It is determined whether or not there is a previous concentration obtained from the calculation result of the medicine ejection calculation. As a result, if there is a previous concentration, an initial concentration is estimated and set based on the previous concentration in step 52, and the process proceeds to step 56. If there is no previous concentration, remote communication by the communication unit 27 is performed in step 53. It is determined whether or not communication with the server 36 is possible.

  If communication is possible as a result of the determination in step 53, the neighborhood from the remote server 36 that the communication unit 27 obtains by communicating with the remote server 36 and supplies it to the operation control unit 25 in step 54. The initial concentration is estimated and set based on the external input concentration obtained based on the information related to the discharge of the disinfecting agent mist or disinfecting agent gas into the disinfecting space 12 by the disinfecting device 35, and the process proceeds to step 56 and communication is not possible. In this case, in step 55, the initial operation density is estimated based on the manual input density input to the operation control unit 25 by operating the input operation unit 28, and the process proceeds to step 56.

  In step 56, it is determined whether or not sensor outputs from the various sensors 26 have arrived. As a result, if sensor outputs have arrived, in step 57, the estimation setting is made in steps 52, 54 or 55. The corrected initial density is corrected in accordance with the sensor output, the density correction is performed in accordance with the sensor output to obtain a corrected density, and the process proceeds to step 58. On the other hand, if the sensor output has not arrived as a result of the determination in step 56, the initial density estimated and set in step 52, 54 or 55 is directly used as the correction density, and the process proceeds to step 58.

  In step 58, the correction density is compared with the reference standard density. The reference standard concentration is included in the information from the remote server 36 that is obtained by the communication unit 27 communicating with the remote server 36 and supplied to the operation control unit 25, or the operation control unit through the input operation unit 28 in advance. 25 or set by being included in a control program stored in the ROM 31 in advance. Then, in step 59, it is determined whether or not the result of the comparison between the correction density in step 58 and the reference standard density indicates that the correction density is smaller than the reference standard density and has not reached the reference standard density. to decide. As a result, when the comparison result in step 58 indicates that the correction concentration does not reach the reference standard concentration, in step 60, the ejection unit 24 is caused to eject the disinfectant chemical mist or the disinfectant chemical gas. In step S61, the correction density is increased by, for example, a very small constant value, and the process proceeds to step S63. On the other hand, if the result of determination in step 59 indicates that the comparison result in step 58 indicates that the correction density is greater than or equal to the reference standard density, in step 62 the correction density is set to a very small constant value, for example. The process proceeds to step 63.

  In step 63, it is determined whether or not a predetermined time has elapsed after the processing in step 61 or 62. As a result, if the predetermined time has not elapsed, the determination in step 63 is repeated, and if the predetermined time has elapsed, the process proceeds to step 64.

  In step 64, it is determined whether or not an end signal that is issued in response to the supply of the control-off signal from the input operation unit 28 to the operation control unit 25 has arrived at the computing means. As a result, when the end signal has arrived, in step 65, the control is ended, and the control operation is ended. On the other hand, if the end signal has not arrived as a result of the determination in step 64, the process returns to step 56, and the processes in steps after step 56 are repeated.
