In the ultraviolet sterilization apparatus, the present invention includes a target temperature detection unit that detects a target temperature of the atmosphere at the target location, and a target humidity detection unit that detects a target humidity of the atmosphere at the target location. When the target temperature detected by the target temperature detection means and the target humidity detected by the target humidity detection means satisfy a predetermined condition, the number of light emitting units that emit ultraviolet rays is increased to increase the luminous intensity. The light intensity correction control to increase is performed.

Moreover, the present invention is characterized in that, in the ultraviolet sterilization apparatus, the light emitting unit also emits visible light when emitting ultraviolet light.

  Exemplary embodiments of an ultraviolet sterilizer according to the present invention will be described below in detail with reference to the accompanying drawings.

<Embodiment 1>
FIG. 1 is a block diagram schematically showing a configuration of an ultraviolet sterilizer according to Embodiment 1 of the present invention. The ultraviolet sterilizer illustrated here includes a light emitting unit 10, an ambient temperature detection unit (ambient temperature detection unit) 21, a target temperature detection unit (target temperature detection unit) 22, and a control unit 30.

  The light emitting unit 10 is configured by an LED or the like that can emit ultraviolet light to a predetermined target portion.

  The ambient temperature detection unit 21 is provided in the vicinity of the place where the light emitting unit 10 is disposed. The ambient temperature detection unit 21 includes a sensor that detects the ambient temperature of the light emitting unit 10 and the detected ambient temperature is provided to the control unit 30 as a detection signal.

  The target temperature detector 22 is disposed at the target location. The target temperature detection unit 22 is configured by a sensor or the like that detects the temperature of the target location (hereinafter also referred to as target temperature), and the detected target temperature is given to the control means 30 as a detection signal.

  The control means 30 comprehensively controls the operation of the ultraviolet sterilizer, and includes a setting storage unit 31, an integrated time calculation processing unit 32, and a luminous intensity setting processing unit 33.

  The setting storage unit 31 presets and stores various kinds of information necessary for the light intensity control process described later. More specifically, the reference temperature, the reference time, the upper limit temperature and the lower limit temperature of the target part are preset and stored.

  The reference temperature is a temperature that serves as a threshold for determining whether the ambient temperature detected by the ambient temperature detection unit 21 is high or low. When the reference temperature is exceeded, it is determined that the light emitting unit 10 is in a high temperature atmosphere.

  The reference time relates to an accumulated light emission time during which the light emission from the light emitting unit 10 is reduced. When the reference time is exceeded, it is determined that the emission of ultraviolet rays by the light emitting unit 10 has decreased by a predetermined rate.

  The upper limit temperature and the lower limit temperature of the target location are threshold values for the temperature range at the target location. More specifically, the upper limit temperature is a temperature at which it is possible to determine that the number of bacteria and the like at the target location increases at a stretch when the temperature exceeds the temperature, and the lower limit temperature is the number of bacteria and the like at the target location when the temperature falls below the temperature. It is a temperature at which it can be determined that does not change much.

  The accumulated time calculation processing unit 32 calculates the accumulated time of ultraviolet light emission by the light emitting unit 10. The accumulated time calculation processing unit 32 performs an accumulated time correction control process described later.

  The luminous intensity setting processing unit 33 sets the luminous intensity of the ultraviolet rays emitted from the light emitting unit 10 and outputs the ultraviolet intensity to the light emitting unit 10. More specifically, the light intensity is set by setting the voltage value applied to the light emitting unit 10 and is output to the light emitting unit 10. In addition, although illustrated here about the luminous intensity setting process part 33 which sets a luminous intensity by setting the voltage value applied to the light emission part 10, in this invention, by setting the electric current value supplied to a light emission part. It may be a light intensity setting processing unit for setting light intensity. The light intensity setting processing unit 33 performs a light intensity correction control process to be described later.

  FIG. 2 is a flowchart showing the processing contents of the light intensity control processing performed by the control means shown in FIG. The operation of the ultraviolet sterilization apparatus according to the first embodiment of the present invention will be described by describing the light intensity control process.

  The control means 30 in the luminous intensity control process calculates the integrated time of ultraviolet light emission by the light emitting unit 10 through the integrated time calculation processing unit 32 (step S110), and executes the integrated time correction control process after calculating the integrated time (step S120). .

  FIG. 3 is a flowchart showing the contents of the accumulated time correction control process shown in FIG. As shown in FIG. 3, when the ambient temperature (detection signal) is input from the ambient temperature detection unit 21 (step S121: Yes), the integrated time calculation processing unit 32 of the control unit 30 stores the input ambient temperature as a setting memory. It is determined whether or not the reference time stored in the unit 31 is exceeded (step S122).

  When the ambient temperature exceeds the reference temperature (step S122: Yes), the accumulated time calculation processing unit 32 determines that the light emitting unit 10 is disposed in a high temperature atmosphere, that is, the light emitting unit 10 has deteriorated. It is determined that the time is relatively fast, and the accumulated time calculated in step S110 is multiplied by a predetermined coefficient to correct the accumulated time to calculate a new accumulated time (step S123). The coefficient used here is obtained from the degree of deterioration of the light emitting unit 10 (LED) over time in a high temperature atmosphere. In step S123, when the coefficient is set to “1.5”, if the integration time calculated in step S110 is “50 hours”, the corrected new integration time is “75 hours”. Such correction of the accumulated time is performed, and then the procedure is returned to end the current accumulated time correction control process.

  On the other hand, when the ambient temperature is equal to or lower than the reference temperature (step S122: No), the accumulated time calculation processing unit 32 returns the procedure and ends the current accumulated time correction control process without performing the process of step S123. . In this case, the integration time calculated in step S110 is employed.

  The control means 30 that has performed the integrated time correction control process determines whether or not the integrated time exceeds the reference time stored in the setting storage unit 31 through the light intensity setting processing unit 33 (step S130).

  When the accumulated time exceeds the reference time (step S130: Yes), the light intensity setting processing unit 33 newly sets the light intensity by increasing the voltage value applied to the light emitting unit 10 by a predetermined ratio (step). S140).

  On the other hand, when the accumulated time is equal to or shorter than the reference time (step S130: No), the light intensity setting processing unit 33 sets the light intensity while maintaining it (step S150).

  The light intensity setting processing unit 33 that newly sets the light intensity or maintains the light intensity in this way performs the light intensity correction control process (step S160).

  FIG. 4 is a flowchart showing the processing contents of the light intensity correction control processing shown in FIG. As shown in FIG. 4, when the target temperature (detection signal) is input from the target temperature detection unit 22 (Step S161: Yes), the light intensity setting processing unit 33 of the control unit 30 sets the input target temperature as the setting storage unit. It is determined whether or not the lower limit temperature stored in 31 is below (step S162).

  When the target temperature is lower than the lower limit temperature (step S162: Yes), the light intensity setting processing unit 33 determines that the target portion is at a temperature at which the number of bacteria or the like does not change so much, and the light intensity newly set in step S140 or Correction is performed to decrease the light intensity maintained and set in step S150 (step S163). More specifically, the luminous intensity setting processing unit 33 corrects luminous intensity by reducing the voltage value applied to the light emitting unit 10 by a predetermined ratio. The light intensity setting processing unit 33 that has performed such correction returns the procedure and ends the current light intensity correction control process.

  On the other hand, when the target temperature is equal to or higher than the lower limit temperature (step S162: No), the light intensity setting processing unit 33 determines whether the target temperature exceeds the upper limit temperature (step S164).

  When the target temperature exceeds the upper limit temperature (step S164: Yes), the light intensity setting processing unit 33 determines that the target portion is at a temperature at which the number of bacteria or the like increases at a stroke, and the light intensity newly set in step S140 or Correction for increasing the luminous intensity maintained and set in step S150 is performed (step S165). More specifically, the luminous intensity setting processing unit 33 corrects luminous intensity by increasing the voltage value applied to the light emitting unit 10 by a predetermined ratio. The light intensity setting processing unit 33 that has performed such correction returns the procedure and ends the current light intensity correction control process.

  By the way, when the target temperature input in step S161 is not less than the lower limit temperature and not more than the upper limit temperature (step S162: No, step S164: No), the luminous intensity setting processing unit 33 is newly set in step S140 or maintained and set in step S150. The luminous intensity maintained is maintained (step S166), and then the procedure is returned to end the current luminous intensity correction control process.

  The control unit 30 that has performed the light intensity correction control process outputs the light intensity after correction or the light intensity after maintenance to the light emitting unit 10 through the light intensity setting processing unit 33 (step S170), and then returns the procedure to this time. The luminous intensity control process is terminated.

  According to the ultraviolet sterilization apparatus according to the first embodiment of the present invention as described above, the control unit 30 measures the accumulated time of ultraviolet light emission by the light emitting unit 10, and the measured accumulated time exceeds the reference time. Furthermore, since the light intensity control is performed to increase the light intensity of the ultraviolet light emitted by the light emitting unit 10 by a predetermined amount, even if the light intensity of the light emitting unit 10 deteriorates with time, the desired light intensity can be emitted, and light is thereby emitted. The sterilizing power can be improved by adjusting the intensity of ultraviolet rays.

  According to the ultraviolet sterilizer, when the ambient temperature detected by the ambient temperature detector 21 exceeds the reference temperature, the control unit 30 performs the accumulated time correction control by multiplying the calculated accumulated time by a predetermined coefficient. The desired luminous intensity can be emitted in consideration of the installation environment of the light emitting unit 10, and the luminous intensity of the emitted ultraviolet light can be adjusted thereby to improve the sterilizing power.

  Moreover, according to the said ultraviolet sterilizer, when the target temperature detected by the target temperature detection part 22 is less than a lower limit temperature, the control means 30 reduces luminous intensity, and when the target temperature exceeds an upper limit temperature. Performs luminous intensity correction control to increase luminous intensity, so that it can emit a desired luminous intensity in consideration of the temperature environment of the target location, thereby adjusting the luminous intensity of the emitted ultraviolet light and improving the bactericidal power Can be.

  The light emitting unit 11 is configured by an LED or the like that can emit ultraviolet light to a predetermined target portion.

  The luminous intensity detection unit 41 is disposed at the target location, and detects the luminous intensity of ultraviolet rays emitted from the light emitting unit 11. The light intensity detector 41 gives the detected light intensity to the control means 50 as a detection signal.

  The target temperature detection unit 42 is disposed at the target location in the same manner as the light intensity detection unit 41. The target temperature detection unit 42 is configured by a sensor or the like that detects the temperature of the target location (hereinafter also referred to as the target temperature), and the detected target temperature is given to the control means 50 as a detection signal.

  The control means 50 controls the overall operation of the ultraviolet sterilizer, and includes a setting storage unit 51 and a light intensity setting processing unit 52.

More specifically, the lower limit luminous intensity, the reference luminous intensity, the upper limit temperature and the lower limit temperature of the target part are preset and stored.

  The lower limit luminous intensity is a minimum threshold value of ultraviolet rays emitted by the light emitting unit 11. When the light intensity of the ultraviolet light emitted by the light emitting unit 11 is lower than the lower limit light intensity, it is determined that the sterilization by the ultraviolet light at the target portion is not sufficient.

  The reference luminous intensity is larger than the lower limit luminous intensity and serves as a threshold value for determining the intensity of ultraviolet light detected by the luminous intensity detection unit 41. If it is lower than the reference luminous intensity, it is determined that the ultraviolet luminous intensity is not desired.

  The upper limit temperature and the lower limit temperature of the target location are threshold values for the temperature range at the target location. More specifically, the upper limit temperature is a temperature at which it is possible to determine that the number of bacteria and the like at the target location increases at a stretch when the temperature exceeds the temperature, and the lower limit temperature is the number of bacteria and the like at the target location when the temperature falls below the temperature. It is a temperature at which it can be determined that does not change much.

  The light intensity setting processing unit 52 sets the light intensity of the ultraviolet light emitted from the light emitting unit 11 and outputs it to the light emitting unit 11. More specifically, the light intensity is set by setting a voltage value applied to the light emitting unit 11 and output to the light emitting unit 11. In addition, although illustrated here about the luminous intensity setting process part 52 which sets a luminous intensity by setting the voltage value applied to the light emission part 11, in this invention, by setting the electric current value supplied to a light emitting part. It may be a light intensity setting processing unit for setting light intensity. The light intensity setting processing unit 52 performs a light intensity correction control process to be described later.

  FIG. 6 is a flowchart showing the processing contents of the light intensity control processing performed by the control means shown in FIG. The operation of the ultraviolet sterilization apparatus according to the second embodiment of the present invention will be described by describing such light intensity control processing.

  When the light intensity detected by the light intensity detector 41 (hereinafter also referred to as detected light intensity) is input (step S210: Yes), the control means 50 in the light intensity control process sets and stores the detected light intensity input through the light intensity setting processor 52. It is determined whether or not it is equal to or greater than the lower limit luminous intensity stored in the unit 51 (step S220).

  When the detected light intensity is not equal to or higher than the lower limit light intensity (step S220: No), that is, when the detected light intensity is lower than the lower limit light intensity, the light intensity setting processing unit 52 is assumed to be insufficiently sterilized by ultraviolet rays at the target location through the notification unit 60. This is notified (step S230), and then the procedure is returned to end the current light intensity control process.

  On the other hand, when the detected light intensity is equal to or greater than the lower limit light intensity (step S220: Yes), the light intensity setting processing unit 52 determines whether or not the detected light intensity input in step S210 is lower than the reference light intensity stored in the setting storage unit 51. (Step S240).

  When the detected light intensity is lower than the reference light intensity (step S240: Yes), the light intensity setting processing unit 52 determines that the light intensity of the ultraviolet light emitted by the light emitting unit 11 is not desired, and the voltage applied to the light emitting unit 11 The light intensity is newly set by increasing the value by a predetermined ratio (step S250).

  On the other hand, when the detected luminous intensity is greater than or equal to the reference luminous intensity (step S240: No), the luminous intensity setting processing unit 52 sets the luminous intensity while maintaining the luminous intensity (step S260).

  The light intensity setting processing unit 52 that newly sets the light intensity or maintains the light intensity in this way performs the light intensity correction control process (step S270).

  FIG. 7 is a flowchart showing the processing contents of the light intensity correction control processing shown in FIG. As shown in FIG. 7, when the target temperature (detection signal) is input from the target temperature detection unit 42 (step S271: Yes), the light intensity setting processing unit 52 of the control unit 50 stores the input target temperature in the setting storage unit. It is determined whether the temperature falls below the lower limit temperature stored in 51 (step S272).

  When the target temperature is lower than the lower limit temperature (step S272: Yes), the light intensity setting processing unit 52 determines that the target portion is at a temperature at which the number of bacteria or the like does not change so much, and the light intensity newly set in step S250 or Correction is performed to decrease the light intensity maintained and set in step S260 (step S273). More specifically, the light intensity setting processing unit 52 corrects light intensity by decreasing the voltage value applied to the light emitting unit 11 by a predetermined ratio. The light intensity setting processing unit 52 that has performed such correction returns the procedure and ends the current light intensity correction control process.

  On the other hand, when the target temperature is equal to or higher than the lower limit temperature (step S272: No), the light intensity setting processing unit 52 determines whether the target temperature exceeds the upper limit temperature (step S274).

More specifically, the luminous intensity setting processing unit 52 corrects luminous intensity by increasing the voltage value applied to the light emitting unit 11 by a predetermined ratio. The light intensity setting processing unit 52 that has performed such correction returns the procedure and ends the current light intensity correction control process.

  By the way, when the target temperature input in step S271 is not less than the lower limit temperature and not more than the upper limit temperature (step S272: No, step S274: No), the luminous intensity setting processing unit 52 performs the luminous intensity newly set in step S250 or the maintenance setting in step S260. The luminous intensity maintained is maintained (step S276), and then the procedure is returned to end the current luminous intensity correction control process.
