(Embodiment 1)
As shown in FIG. 1, the hand sterilization apparatus 1 includes an air reservoir 4 having an inlet 2 and an outlet 3, a heating unit 5, a blowing unit 6, and a control unit 7. The heating means 5 is located in the air reservoir 4 and is disposed between the suction port 2 and the air outlet 3, and the air in the air reservoir 4 is heated by the heating means 5. Examples of the heating means 5 include heating wires such as nichrome wire and Kanthal wire, or far-infrared heaters such as halogen lamp heaters, carbon lamp heaters and ceramic heaters. However, the heating means 5 is limited to the heating means 5 listed here. Any heating means 5 may be used as long as it generates heat and can be controlled in a short time. The air blowing means 6 is disposed in the air reservoir 4 and is connected to the air outlet 3 so that the air in the air reservoir 4 is blown out of the air reservoir 4 from the air outlet 3. As the air blowing means 6, for example, a fan motor using a sirocco fan or a propeller fan is used, and any air blowing means 6 can be used as long as it is controllable to generate airflow and blow air in a certain direction. It doesn't matter.

  The control means 7 is arranged to control the heating means 5 and the air blowing means 6, and controls the heating of air by the heating means 5 and the air blowing by the air blowing means 6. As the control means 7, for example, a switch or the like that can be turned on and off with a finger, the heating means 5 and the air blowing means 6 can be driven by turning on and off the switch, and for example, the heating means 5 that is an electric heater, for example. And a circuit that can drive the blowing means 6 that is a fan motor. Any control means can be used as long as it can control the driving of the heating means 5 and the blowing means 6. May be used. When the heating means 5 and the air blowing means 6 are materials that consume power, the hand sterilization apparatus 1 needs to obtain power from an AC power source or the like. In this case, the hand sterilization apparatus 1 needs to be connected to the AC power source. The supply of electric power is not limited to an AC power source, and may be an item including an independent power source such as a power generation device. Air in the air reservoir 4 is blown out by the air blowing means 6 and simultaneously air flows into the air reservoir 4 from the suction port 2. Since the air that has flowed into the air reservoir 4 stays in the air reservoir 4 for a certain period of time until it is blown out from the air outlet 3, a sufficient time for the air to be warmed by the heating means 5 is ensured. By providing the air reservoir 4, the air by the heating means 5 is efficiently heated, and the air temperature efficiently rises to a temperature at which a sterilizing effect is obtained. Air that has been efficiently heated to a temperature at which a sterilizing effect is obtained is blown out from the blowout port 3 and wiped onto the surface of the object to be sterilized 8, so that harmful microorganisms such as germs attached to the surface of the object to be sterilized 8 It is efficiently heat-denatured and the surface of the object 8 to be sterilized is sterilized efficiently.

  Here, the object to be sterilized 8 is skin such as hands and fingers, and examples of bacteria present on the skin include bacteria passing through the skin such as Escherichia coli and Staphylococcus aureus. Since Escherichia coli is thermally sterilized from 55 ° C., the surface of the skin such as fingers is sterilized by heating the air temperature in the air reservoir 4 to 55 ° C. or higher by the heating means 5. In addition, by heating the air in the air reservoir 4 to 55 ° C. or higher in advance, the air blowing means 6 is driven, and at the same time, air of 55 ° C. or higher is instantaneously applied to the skin surface of the object 8 to be sterilized, for example. The surface of the finger skin can be sterilized and disinfected in a short time.

  In the above configuration, the air in the air reservoir 4 is efficiently heated by the heating means 5, the air temperature efficiently rises to a temperature having a sterilizing effect, and the air whose temperature has risen is sterilized by the blowing means 6. Since the germs on the surface of the object 8 to be sterilized are thermally denatured efficiently by being wiped on the surface, the surface of the object 8 to be sterilized is sterilized and disinfected in a short time.

  As described above, according to the finger sterilization apparatus 1 of Embodiment 1 of the present invention, the heating means 5 is disposed between the suction port 2 and the blowout port 3 of the air reservoir 4 to efficiently heat the air. Thus, the air heated efficiently and wiped onto the surface of the object 8 to be sterilized by the air blowing means 6 can efficiently sterilize the surface of the object 8 to be sterilized in a short time.

  Moreover, since air is used as the medium for heat sterilization, the surface of the object to be sterilized 8 can be sterilized more safely than when alcohol or a disinfectant is used. Even when the object to be sterilized 8 is a human skin such as a hand or a finger, since the hand or finger itself is not damaged by heat due to the latent heat when moisture evaporates from the skin surface, burns are caused. It is possible to sterilize and disinfect only the surfaces of hands and fingers without having to do so.

  Further, when the object to be sterilized 8 is human skin such as a hand or a finger, if the hand sterilization apparatus of the present invention is used, alcohol or disinfectant is not directly wiped onto the skin surface. Do not suffer from allergic symptoms or rough skin symptoms to the disinfectant.

  In addition, since the hand sterilizing apparatus of the present invention can always use the medium to be sterilized as air, there is no need for a medium for sterilization, no additional supplementation with alcohol or disinfectant, It can be used continuously for the purpose of sterilizing the surface of the object 8.

  Moreover, since air which is a medium to be sterilized is heated to a temperature having a sterilizing effect by the heating means 5, it does not become a hotbed of various germs, so that the sanitary condition does not deteriorate.

  In the first embodiment, the suction port 2 and the blower port 3 are described as open holes in the air reservoir 4. However, even when a valve or other openable structure is used, the blowing means is similarly used. If the airflow can be generated in a certain direction by 6, the above-mentioned sterilization can be performed.

(Embodiment 2)
FIG. 2 shows the hand sterilization apparatus 1 in which the air reservoir 4 is composed of a heat insulating material 9. Although the air in the air reservoir 4 is raised to a temperature having a sterilizing effect by the method described in the first embodiment, the heated air is hardly cooled by configuring the air reservoir 4 with the heat insulating material 9. The heat insulating material is, for example, an inorganic fiber heat insulating material such as glass wool or rock wool, a foamed plastic heat insulating material such as polystyrene, polyurethane or urethane, or a wood fiber heat insulating material such as cellulose fiber. Even if this material is used, the same effect can be obtained if a material having a heat insulating effect is used.

  In the above configuration, since the air heated in the air reservoir 4 can be prevented from being cooled by the outside air, the air in the air reservoir 4 is easily heated and has a more effective sterilizing effect. It becomes possible to heat to temperature.

  As described above, according to the finger sterilization apparatus 1 of the second embodiment of the present invention, the air in the air reservoir 4 can be heated more efficiently. It can be sterilized.

  In addition, since the air temperature in the air reservoir 4 is not easily lowered by the heat insulating material 9, it is possible to heat and hold the air in the air reservoir 4 in advance, and in this case, the object to be sterilized 8 can be immediately wiped with air heated to a temperature having a sterilizing effect, and the surface of the object 8 to be sterilized can be sterilized more quickly. For example, when electric power is used as the heating means 5, energy loss due to heat radiation of the heated air is reduced, so that energy efficiency is improved.

  In FIG. 2, the hand sterilizer 1 in which the air reservoir 4 is configured by the heat insulating material 9 is described. However, even when a material other than the heat insulating material is used, for example, a hollow heat insulating structure is taken. If it is, the air temperature in the air reservoir 4 can be maintained, and similarly, the air in the air reservoir 4 can be efficiently heated.

(Embodiment 3)
FIG. 3 shows the finger sterilizer 1 provided with the temperature detecting means 10. The temperature detecting means 10 is installed so as to detect the air temperature in the air reservoir 4, and is arranged so that the detected temperature can be transmitted to the controller 7. The temperature detection means 10 is, for example, a contact temperature sensor such as a platinum resistance thermometer, thermistor, or thermocouple, and is disposed in contact with the air in the air reservoir 4, but is limited to these. As long as the temperature of the air reservoir 4 can be transmitted to the controller 7 even if other methods are used, the air temperature can be accurately controlled in the same manner regardless of the temperature detection means 10. Will be possible.

  In the above configuration, by feeding back the information detected by the temperature detecting means 10 to the control section 7, the control section 7 can control the heating means 5 depending on the air temperature in the air reservoir 4, and the sterilization is possible. It becomes possible to accurately heat to an effective temperature.

  As described above, according to the finger sterilization apparatus 1 shown in the third embodiment of the present invention, the temperature in the air reservoir 4 can be accurately raised to a temperature having a sterilizing effect, and accordingly, the object to be sterilized. The surface of the object 8 can be sterilized accurately.

  Further, since the temperature of the heated air can be adjusted, the air temperature can be changed in accordance with the inspection object 8. For example, when the object 8 to be sterilized is a skin surface such as a finger, it is desirable that the air temperature is adjusted to 100 ° C. or less in order to prevent thermal damage to the skin due to overheating. Further, in order to always exhibit the same sterilizing effect, at least the temperature of the air blown out from the blowout port 3 needs to be always adjusted to be constant. Therefore, the hand sterilization apparatus 1 having a stable sterilization effect can be obtained.

(Embodiment 4)
FIG. 4 shows a hand sterilization apparatus 1 provided with a humidity detection means 11. The humidity detecting means 11 is installed so as to detect the air humidity in the air reservoir 4 and is arranged so that the detected humidity can be transmitted to the control unit 7. Examples of the humidity detecting means 11 include a humidity sensor such as a polymer film humidity sensor, a ceramic humidity sensor, and an electrolyte humidity sensor. However, the humidity detecting means 11 is not limited to these, and the air reservoir 4 may be of other types. Any humidity detecting means 11 may be used as long as it can transmit the air humidity information to the control unit 7.

  In the above configuration, the control unit 7 can control the heating unit 5 depending on the air humidity in the air reservoir 4 by feeding back the information detected by the humidity detection unit 11 to the control unit 7. It becomes possible to accurately heat to an effective temperature.

  As described above, according to the finger sterilization apparatus 1 shown in the fourth embodiment of the present invention, when the air humidity in the air reservoir 4 is high, the heating amount is lowered, and on the contrary, the air humidity in the air reservoir 4 is reduced. When the temperature is low, the heating amount can be increased and the air temperature can be adjusted to a sterilizing effect.

(Embodiment 5)
FIG. 5 shows the finger sterilization apparatus 1 provided with the vaporizing means 12 and the moisture retaining means 13. The vaporizing means 12 is disposed in the air reservoir 4 and evaporates moisture to increase the air humidity in the air reservoir 4. The moisture holding means is arranged to hold a certain amount of moisture and supply the held moisture to the vaporizing means 12. It should be noted that the moisture holding means may be disposed at any location as long as moisture can be supplied to the vaporizing means 12 either inside or outside the air reservoir 4. Further, the vaporization means 12 is arranged so that the vaporization of water is controlled by the control unit 7. The vaporization means 12 may be, for example, an ultrasonic atomizer, but may have a large surface area that has water-absorbing activity and comes into contact with air, such as a non-woven fabric, and may increase the evaporation efficiency. In addition, even if it is a means other than this, as long as the vaporization amount can be adjusted by the control part 7, any vaporization means 12 may be used. For example, when the vaporizing means 12 is an ultrasonic atomizer, the atomization amount can be adjusted by adjusting the output of the ultrasonic vibration, and the vaporizing means 12 is a nonwoven fabric. If it is a thing, there exists means, such as bending a nonwoven fabric so that a nonwoven fabric may adjust the surface area which contacts with air. In addition, the water holding means includes a container that can contain water, but it may be integrated with the vaporizing means 12 as long as it is a nonwoven fabric that can vaporize simultaneously held water that can hold water. Absent.

  In the above configuration, the moisture retained in the moisture retaining means 13 is supplied to the vaporizing means 12, and the moisture supplied to the vaporizing means 12 is released into the air reservoir 4 by the vaporizing means 12, and the humidity in the air reservoir 4 is Rises.

  Thus, according to the hand sterilization apparatus 1 shown in the fifth embodiment of the present invention, when the air humidity in the air reservoir 4 is low, the humidity in the air reservoir 4 can be increased by the vaporizing means 12. And the sterilizing effect of the heated air can be enhanced. The principle that the sterilizing effect increases when the air humidity increases will be described below. When bacteria such as Escherichia coli and Staphylococcus aureus are sterilized by heat, its heat resistance is known to depend on the environmental conditions around the microorganism, and the moisture around the microorganism, that is, water activity, is the heat resistance of the microorganism. It is known to have a big impact on The water activity is expressed by (water vapor pressure of the object to be sterilized 8 to which microorganisms adhere) / (saturated water vapor), that is, indicates relative humidity. It is known that when the water activity is high, the heat resistance characteristics of the microorganisms are lowered and it is well sterilized. Therefore, the surface of the object to be sterilized 8 is adhered to the surface of the object 8 to be sterilized by wiping the air with high humidity. By increasing the relative humidity around the microorganism, it becomes possible to sterilize efficiently.

  Further, when the object to be sterilized 8 is the skin surface such as a hand or a finger, the humidity of the skin surface is increased by wiping high-humidity air, the cooling effect of the skin surface by latent heat is maintained, and the high-temperature air Even if the skin is wiped, the skin surface is not damaged by heat, and the bactericidal effect can be enhanced.

(Embodiment 6)
FIG. 6 shows the finger sterilization apparatus 1 provided with the distance detection means 14 for detecting the distance to the object 8 to be sterilized. The distance detection means 14 is connected to the control unit 7, measures the distance from the outlet 3 to the object to be sterilized 8, and feeds back the information to the control unit 7. Examples of the distance detection means 14 include an ultrasonic distance sensor and a laser distance sensor. However, any distance detection means 14 may be used as long as distance information can be fed back to the control unit 7. It doesn't matter.

  In the above configuration, the temperature or humidity of the air in the air reservoir 4 can be increased according to the distance from the outlet to the surface of the object 8 to be sterilized.

  Thus, according to the hand sterilization apparatus 1 shown in the sixth embodiment of the present invention, when the object 8 to be sterilized is at a distance from the hand sterilization apparatus 1, the heating temperature is lowered, or the object 8 to be sterilized is the finger. When the distance is far from the sterilizer, the sterilization effect due to thermal damage can be stabilized by controlling the heating temperature to be increased. For example, in the case where the object 8 to be sterilized is located far away, the air heated to a temperature having a sterilizing effect is cooled by heat dissipation until it reaches the surface of the object 8 to be sterilized and exhibits a sufficient sterilizing effect. It becomes difficult. In such a case, the sterilization effect can be maintained by increasing the temperature of the air to be wiped against the object to be sterilized according to the distance to the object 8 to be sterilized. On the other hand, when the distance to the object to be sterilized 8 is short, the degree of cooling by heat dissipation is low, so that the sterilizing effect can be maintained without increasing the temperature and there is no need to significantly increase the air temperature. Therefore, energy efficiency is also good.

(Embodiment 7)
FIG. 7 shows the finger sterilizer 1 provided with surface temperature detecting means 15 for detecting the temperature of the surface of the object 8 to be sterilized. The surface temperature detection means 15 is connected to the control unit 7, measures the temperature of the surface of the object to be sterilized 8 to which heated air is wiped, and feeds back the information to the control unit 7. Examples of the surface temperature detection means 15 include non-contact temperature sensors such as thermal infrared sensors such as thermistors and thermobiles, and quantum infrared sensors such as photodiodes. Any material can be used as long as the temperature information on the surface of the object to be sterilized 8 can be fed back to the control unit 7.

  In the said structure, the temperature or humidity of the air in the air reservoir part 4 can be raised according to the temperature of the to-be-sterilized target object 8 surface.

  Thus, according to the hand sterilization apparatus 1 shown in Embodiment 7 of the present invention, when the temperature of the surface of the inspection object 8 is high, the heating temperature is lowered, or when the temperature of the surface of the inspection object 8 is low. The heating temperature can be raised, and even when the surface temperature of the object 8 to be sterilized is different, a similar sterilizing effect can be obtained, and a stable sterilizing effect can be obtained.

(Embodiment 8)
FIG. 8 shows the finger sterilization apparatus 1 provided with surface moisture detection means 16 for detecting the humidity of the surface of the object 8 to be sterilized. The surface moisture detection means 16 is connected to the control unit 7, detects the moisture held on the surface of the object to be sterilized 8 to which heated air is wiped, and feeds back the information to the control unit 7. The surface moisture detection means 16 includes, for example, a moisture measurement means such as a dielectric constant meter, and the surface moisture is measured by contacting the surface of the object 8 to be inspected. Any material can be used as long as it can feed back the information on the surface moisture to the control unit 7.

  In the said structure, the temperature or humidity of the air in the air reservoir part 4 can be raised according to the moisture content of the to-be-sterilized target object 8 surface.

  Thus, according to the finger sterilization apparatus 1 shown in the eighth embodiment of the present invention, the heating temperature is lowered or the surface of the object to be sterilized 8 is lowered when the water held on the surface of the object 8 to be inspected is high. When the amount of water held is low, the heating temperature can be raised, and even when the amount of water held on the surface of the object 8 to be sterilized is different, the same sterilizing effect can be obtained, and stable sterilization is achieved. The effect can be obtained.

The filter 17 is disposed so as to cover the suction port 2 and the air outlet 3, and is disposed so as to filter the air flowing into and out of the air reservoir 4. The filter 17 is an air filter such as a HEPA filter or a non-woven fabric. For example, if the filter 17 is easy to be attached to and detached from the suction port 2 and the blower port 3, it can be replaced if it becomes dirty depending on the use situation. . In addition, any other means can be used as long as it is a means capable of removing dust, microorganisms, and the like accompanying the air flow into and out of the air reservoir 4 using other means.

  In the above configuration, the air flowing into the air reservoir 4 is sterilized by the filter 17, and the inside of the air reservoir can be kept hygienic. In addition, since the heated air that is wiped onto the object to be inspected 8 is sterilized by the filter 17, it is possible to prevent dust or microorganisms from being wiped onto the object to be sterilized, so that sterilization can be performed more hygienically.
