  According to the dryer of patent document 1, the razor head after water washing can be dried with a dry structure, or the secondary battery of an electric razor can be charged with a charge structure. Further, the heat of the heater can be conducted to the razor head to sterilize the outer blade and the inner blade, and further, the LED can be sterilized by irradiating ultraviolet rays with the LED toward the blade portion. However, since the LED that irradiates ultraviolet rays and the blade portion are separated, the blade portion cannot be irradiated with sufficient ultraviolet rays, and sterilization by the LED cannot be reliably performed.

  In that respect, the charger of Patent Document 2 irradiates ultraviolet light with a UV lamp provided inside the razor head and a UV lamp provided inside the cap facing the razor head. Of course, germs present on the inner and outer surfaces of the outer blade holder can be sterilized more reliably. However, since the drying structure such as a heater and a blower fan is not provided unlike the dryer of Patent Document 1, the razor head that has been washed and dried is not only naturally dried but also takes time to dry.

The object of the present invention is to remove the hair of the hair removal head such as a razor head and disinfect bacteria by using the heat of the heater and the fungicidal action of the sterilizing light. To provide an apparatus.
An object of the present invention is to provide a sterilization drying apparatus for a hair removal device having a charging function in addition to a sterilization drying function of a hair removal device that has been wet or washed with water.

  The present invention relates to a sterilization drying device for drying and sterilizing a hair removal head 2 of a hair removal device. As shown in FIG. 1, the housing 15 of the sterilization drying device supports the hair removal head 2. A head loading unit 21 is provided. A heater unit 25 that supplies drying heat to the hair removal head 2 and a sterilization lamp 26 that irradiates the hair removal head 2 with sterilization light are arranged in the head loading unit 21.

  A heater 76 constituting the heater unit 25 is annularly arranged on the inner surface of the bottom wall 21 b of the head loading unit 21 that faces the hair removal head 2 loaded in the head loading unit 21. The germicidal lamp 26 is disposed in a space surrounded by the heater 76.

  The bottom wall 21 b of the head loading unit 21 includes a heat transfer wall 34 that faces the heater 76, and a light guide wall 35 that faces the disposition area of the germicidal lamp 26. The heat transfer wall 34 is formed of a rubber-like elastic material having excellent heat conductivity. The light guide wall 35 is formed of a plate material that allows transmission of ultraviolet light.

  As shown in FIG. 9, the heater unit 25 includes a heater base 75, a heater 76 that is annularly disposed on the heater base 75, and a heat transfer made of a metal plate that is disposed between the heater 76 and the heat transfer wall 34. And a plate 77. The light guide wall 35 is attached to a window opening 33 provided in the heat transfer wall 34 and sealed in a watertight manner by the heat transfer wall 34.

  A blower 24 that feeds dry air is provided inside the housing 15. A drying air inlet 32 for feeding and guiding the drying air supplied from the blower 24 toward the head loading unit 21 is opened adjacent to the bottom wall 21b of the head loading unit 21 (see FIG. 8). .

  Adjacent to the head loading portion 21, a placement portion 22 that supports the hair removal device is formed in a dent. A drying air introduction port 32 is opened in the bottom wall 22 b of the mounting portion 22.

  The lower half of the head loading portion 21 including the bottom wall 21b and the lower half of the placement portion 22 including the bottom wall 22b are integrated as a tray body 30 formed of a rubber-like elastic material having excellent thermal conductivity. To form.

  The drying air inlet formed in the bottom wall 22b of the mounting portion 22 also serves as the drainage port 32 for the water that has flowed down from the hair remover to the head loading portion 21.

  The bottom wall 21 b of the head loading unit 21 is inclined downward from the head loading unit 21 side toward the drain port 32 of the bottom wall 22 b of the mounting unit 22.

  In the housing 15, the head loading unit 21, the mounting unit 22, and the charging unit 23 are arranged in the order of description. Each of the bottom wall 21 b of the head loading unit 21 and the support wall 44 of the mounting unit 22 that continues to the base 37 of the charging unit 23 is inclined downward toward the drain port 32.

  In the vicinity of the heater 76, a temperature sensor 78 that detects the environmental temperature where the hair remover is placed and detects the heater temperature after the heater 76 is driven is disposed. The housing 15 is provided with a control circuit that controls the operating states of the heater unit 25, the blower 24, and the germicidal lamp 26. The control circuit compares the detection signal of the environmental temperature of the temperature sensor 78 with a preset temperature condition, and changes the processing time for sterilization and drying to a larger or smaller value according to the environmental temperature. Further, the control circuit maintains the heat generation temperature of the heater 76 at the set temperature according to the detection signal of the temperature sensor 78 while the heater unit 25 is being driven.

  The control circuit is configured to drive the heater unit 25 prior to the start of the blower 24 and start the blower 24 after a predetermined time has elapsed. Prior to the start of the blower 24, the hair removal head 2 is sterilized and dried only by the heat of the heater 76, and then sterilized and dried by the interaction between the heat of the heater 76 and the drying air supplied from the blower 24. I do.

  The control circuit is configured to drive the heater 76 and the blower 24 and stop the blower 24 after a predetermined time has elapsed. At the final stage of the sterilization drying process, sterilization drying is performed again only with the heat of the heater 76.

  The control circuit is configured to stop driving the heater 76 and start the blower 24 when the sterilization drying process is completed. After the sterilization and drying process, the hair removal head 2 is cooled with drying air at room temperature.

  A photocatalytic film is formed on the surface of the parts constituting the hair removal head 2.

  In the present invention, a heater unit 25 and a sterilizing lamp 26 are provided in the head loading portion 21 of the housing 15 so that heat for drying and sterilizing light simultaneously act on the hair removal head 2 for sterilization and drying. I was able to do it. Thus, when the hair removal head 2 is sterilized and dried by the heating action of the heater unit 25 by the heat and the sterilization action of the sterilizing lamp 26 by the ultraviolet light, the germs existing inside and outside the hair removal head 2 are surely sterilized. The hair removal head 2 can be maintained in a sanitary state while maintaining a dry state in which there is no room for germs to propagate.

  When the heater 76 is annularly disposed and the germicidal lamp 26 is disposed in a space surrounded by the heater 76, each of the heater 76 and the germicidal lamp 26 is disposed in the state closest to the hair removal head 2, and is heated by the heater 76. And sterilization by the sterilization lamp 26 can be effectively performed. Further, the heat conduction region by the heater 76 and the sterilization region by the sterilization lamp 26 are adjacent to each other inside and outside, so that the heater 76 and the sterilization lamp 26 can be arranged in a state where there is no waste of space. Can be

  When the heat transfer wall 34 and the light guide wall 35 constitute the bottom wall 21b of the head loading portion 21 and the heat transfer wall 34 is formed of a rubber-like elastic material having excellent thermal conductivity, the head loading portion 21 is loaded. The hair removal head 2 can be received by the heat transfer wall 34 having cushioning properties. Further, the heat of the heater 76 can be effectively conducted to the hair removal head 2 through the heat transfer wall 34. Furthermore, since the hair removal head 2 can be received and supported in a stable state by the light guide wall 35 formed of a plate material that allows the transmission of ultraviolet light, the heat applied to the hair removal head 2 loaded in the head loading section 21 as a whole. Conduction and sterilization light irradiation can be performed effectively.

  When the heater unit 25 is configured by the heater base 75, the heater 76, the heat transfer plate 77, and the like, the heat of the heater 76 can be conducted to the heat transfer wall 34 in a state of being diffused in a planar shape by the heat transfer plate 77. The hair removal head 2 can be heated evenly. Further, by sealing the light guide wall 35 attached to the window opening 33 of the heat transfer wall 34 in a watertight manner with the heat transfer wall 34, water flowing from the hair removal head 2 loaded in the head loading unit 21 is Intrusion to the heater unit 25 side can be reliably prevented. Since the periphery of the light guide wall 35 is sealed using the heat transfer wall 34, it is not necessary to provide a separate sealing structure for the light guide wall 35, and external impact is absorbed by the heat transfer wall 34 and guided. The optical wall 35 can be well prevented from being displaced.

  When the blower 24 is provided inside the housing 15 so that the dry air fed from the blower 24 can be fed toward the head loading unit 21 through the dry air inlet 32, the heater 76 and the germicidal lamp are provided. In addition to the sterilization and drying action of 26, the drying of the hair removal head 2 can also be promoted by the drying promoting action of the drying wind. Therefore, it is possible to promote the evaporation of water adhering to the inner and outer surfaces of the hair removal head 2 and perform sterilization drying in a shorter time. In addition, since a part of the supplied drying air is heated by the heat of the heat transfer wall 34 or the heat of the hair removal head 2 and the relative humidity is lowered, the hair removal head 2 can be further reliably dried. There is also an advantage that the water vapor evaporated from the hair removal head 2 inside the head loading unit 21 is discharged out of the sterilization / drying device with dry air, so that the inside of the head loading unit 21 can be easily dried.

  When the mounting portion 22 is formed in a recess adjacent to the head loading portion 21 and the dry air inlet 32 is opened in the bottom wall 22b, the body portion 1 of the hair removal device when not in use is loaded into the mounting portion 22. By inserting the lower part into the drying air inlet 32, the sterilization drying apparatus can be used as a storage stand. When the sterilization drying apparatus is used as a storage stand, the electric razor can be properly stored and stored by a rough operation such that the lower portion of the main body 1 enters the mounting portion 22. Furthermore, the hair remover can be taken out from the sterilization / drying device by simply grasping and lifting the main body 1 and can be easily attached and detached.

  When the lower half of the head loading portion 21 and the lower half of the placement portion 22 are integrally formed as a tray body 30 with a rubber-like elastic material, the bottom wall 21b of the head loading portion 21 and the bottom of the placement portion 22 are formed. Compared with the case where the walls 22b are individually provided, the number of components of the sterilization drying apparatus can be reduced. Moreover, since the weight of the hair remover loaded on the head loading unit 21 and the mounting unit 22 is received by the bottom walls 21b and 22b made of a rubber-like elastic material, the head loading unit 21 and the mounting unit 22 are loaded. The hair removal device can be prevented from sliding by the frictional force of the bottom walls 21b and 22b, and the hair removal device can be supported in a stable state.

  According to the sterilization drying apparatus in which the drying air introduction port also serves as the water drainage port 32, the water flowing down from the hair removal device to the head loading unit 21 or the mounting unit 22 is discharged from the drainage port 32, It is possible to prevent water from collecting on the bottoms of the head loading unit 21 and the mounting unit 22. Further, when the hair removal head 2 loaded in the head loading unit 21 is sterilized and dried, the water that has flowed down from the hair removal head 2 is quickly discharged from the drain port 32 to promote drying of the hair removal head 2. it can.

  When the bottom wall 21b of the head loading unit 21 is inclined downward toward the drain port 32, water or water droplets flowing down from the hair removal head 2 can surely flow down toward the drain port 32 and be drained. The drying of the hair removal head 2 can be further promoted. In addition, the drying air fed to the head loading unit 21 is flow-guided by the bottom wall 21b and the passage of the drying air in the head loading unit 21 is promoted, so that the hair removal head 2 can be dried more effectively.

  When the bottom wall 21b of the head loading unit 21 and the support wall 44 of the mounting unit 22 are inclined downward toward the drain port 32, the hair remover washed with water is washed with the head loading unit 21, the mounting unit 22, or the charging unit. In the state loaded in 23, all of the water flowing down from the hair remover can be reliably guided to the drain port 32. Further, the water that has flowed down from the hair remover is collected at the bottom wall 21b and the support wall 44 and flows to the drain port 32 to be discharged, so that the water other than the head loading unit 21, the mounting unit 22, or the charging unit 23 is discharged. It can be prevented from spreading to the part or flowing out to the peripheral part of the sterilization drying apparatus.

  When the temperature sensor 78 arranged in the vicinity of the heater 76 is used to detect the environmental temperature where the hair remover is placed, and when the heater temperature after driving is detected, the environmental temperature is detected by only one temperature sensor 78. And the heater temperature can be detected, and the control structure of the sterilization drying apparatus can be simplified accordingly. Further, the detection signal of the environmental temperature of the temperature sensor 78 is compared with a preset temperature condition, and the processing time for sterilization drying is changed according to the environmental temperature by the control circuit, thereby eliminating the sterilization drying. The processing time required for processing can be optimized in response to changes in the season or temperature. Therefore, the result of performing the sterilization drying can be prevented from varying due to a change in season or temperature, and the sterilization drying of the hair removal head 2 can always be performed appropriately. Further, when the heater unit 25 is driven, the heat generation temperature of the heater 76 can be maintained at the set temperature by the control circuit in accordance with the detection signal of the temperature sensor 78.

  When the drive timing of both 24 and 25 is controlled so that the heater unit 25 is driven prior to the start of the blower 24, the hair removal head 2 is dried by the heat of the heater 76, and then the heat and air of the heater 76 are blown. Drying can be performed by interaction with the drying air fed from the vessel 24. In a situation where the hair removal head 2 is heated in advance by the heat of the heater 76, the temperature of each member constituting the hair removal head 2 can be increased to a predetermined temperature, and evaporation of water adhering to each member can be promoted. Further, in the situation where the blower 24 is driven in addition to the heater 76, the inside of the head loading unit 21 is maintained in a state where it is easy to dry while blowing off the water vapor evaporated by the heat of the heater 76 with the drying air. Drying can be further promoted by wind interaction.

  When the heater 76 and the blower 24 are controlled so that heating is performed again only with the heat of the heater 76 at the final stage of the sterilization drying process, the temperature of each member constituting the hair removal head 2 is increased to a predetermined temperature. Each member from which water has been removed can be thermally sterilized. Therefore, the inner and outer surfaces of the hair removal head 2 can be surely sterilized and dried to be in a sanitary state.

  When driving of the heater 76 is stopped at the time when the sterilization drying process is finished and the heater 76 and the blower 24 are controlled so as to start the blower 24 again, the heated hair removal head 2 is cooled with dry air. To return to normal temperature. Therefore, even when the hair remover is used immediately after being treated with the sterilization and drying apparatus, the user does not feel hot by touching the hair removal head 2, and the hair remover is continuously comfortable. Can be used for

  When a photocatalytic film is formed on the surface of the parts constituting the hair removal head 2, the organic matter contained in the debris, sebum, sweat, etc. adhering to the portion where the photocatalytic film is formed is decomposed by the photocatalytic film to decompose the organic matter, etc. The generation of an unpleasant odor can be prevented, and the inner and outer surfaces of the hair removal head 2 can be kept in a more hygienic state.

In FIG. 9, the heater unit 25 includes a rectangular frame-shaped heater base 75 that is long on the left and right, a sheathed heater (heater) 76 that is annularly disposed around the heater base 75, a heat transfer plate 77 made of a metal plate, A temperature sensor 78 for monitoring the heat generation temperature and a temperature fuse (not shown) are included. The temperature sensor 78 is provided to detect the heater temperature after the sheathed heater 76 is driven, but detects the environmental temperature where the electric razor is placed immediately before the use of the sterilization drying apparatus is started. Also used for. As shown in FIG. 7, the heater unit 25 is fixed to the peripheral wall on the upper surface side of the LED opening 63 with screws 79, and the heat transfer plate 77 is in close contact with the lower surface periphery of the window opening 33 of the tray body 30. (See FIG. 1). Accordingly, the heat of the sheathed heater 76 (about 65 ° C.) can be conducted to the heat transfer wall 34 of the head loading section 21 through the heat transfer plate 77.

  In a state where the substrate unit 61 is assembled to the base body 17, the six sterilization LEDs 26 enter the LED openings 63 and face the transparent window plate 35 fitted in the window openings 33. Therefore, in the state where the sterilization LED 26 is lit, ultraviolet light can be irradiated to the inside of the head loading unit 21 through the window plate 35. The window plate 35 is fitted into the window opening 33, and the periphery thereof is sealed with a heat transfer wall 34. Therefore, even when washing water flows down from the razor head 2 loaded in the head loading unit 21, the water does not enter the heater unit 25 through the window opening 33.

  4 and 5, the drain pan 27 is integrally provided with a rectangular shallow dish-shaped portion 84 that is long on the left and right sides, and knob portions 85 that are erected on both the left and right sides of the dish-shaped portion 84. The main body 18 is detachably attached to the attachment port 56 in a state of crossing the main body 18 from side to side. Specifically, the drain pan 27 can be fixed to the housing body 18 by engaging the engaging claw 86 provided on the upper portion of the knob portion 85 with the engaging concave portion 87 provided above the inner surface of the mounting port 56. Further, the drain pan 27 can be removed from the housing body 18 by releasing the engagement between the engagement claws 86 and the engagement recesses 87 while elastically deforming the pair of knob portions 85 inward.

  As shown in FIG. 8, the rear half of the upper surface of the drain pan 27 attached to the housing body 18 is covered by the bottom wall 88 of the base body 17, and the remaining portion not covered by the bottom wall 88 is the bottom. It faces the drain port 32 of the tray body 30 through an opening 89 opened in the wall 88. The drain pan 27 attached to the base body 17 can be visually recognized through the drain port 32. Therefore, when using the sterilization drying apparatus, the presence / absence and mounting state of the drain pan 27 can be confirmed by visually checking the drain pan 27 from the upper surface side of the housing 15 through the drain port 32.

  The electric razor washed and washed with water is dried and disinfected with the razor head 2 loaded in the head loading unit 21. However, if the axial fan 24, the heater unit 25, and the sterilization LED 26 are operated in a state where the razor head 2 is not loaded in the head loading unit 21, useless power is consumed as well as the head loading unit 21. The surrounding wall is unnecessarily heated to a high temperature, and there is a risk that the fingertip touches the high temperature portion and burns. In order to prevent such a situation with certainty, a switch lever 92 is provided above the stepped portion 46 of the rib wall 41 on one side.

  As shown in FIG. 1, in a state where the razor head 2 of an electric razor is loaded in the head loading portion 21 in an inverted posture, the switch lever 92 is pushed down by the protruding end of the housing portion 10 to turn on the switch element 93. In this state, by pressing the start switch 51, the axial fan 24 and the heater unit 25 can be started, and the sterilization LED 26 can be turned on.

  The sterilization / drying apparatus configured as described above is used in a state where the electric razor is placed on any of the head loading unit 21, the placing unit 22, and the charging unit 23. When the unused electric razor is simply stored and stored, as shown in FIG. 10, the lower portion of the main body 1 is inserted into the mounting portion 22, and the upper rear surface of the main body 1 is leaned against the holding ring 16. The electric shaver in this state is supported at the lowest position of the sterilization / drying apparatus, and the upper and lower two portions of the main body 1 are stably supported at the two portions of the mounting portion 22 and the holding ring 16. . At this time, it is not necessary to strictly position the electric razor with respect to the mounting portion 22, and the electric razor can be properly stored and stored by a rough operation such that the lower portion of the main body portion 1 enters the mounting portion 22. Further, the electric razor can be easily taken out from the sterilization / drying device by simply grasping and lifting the main body 1 or the razor head 2.

  When the electric shaver is in the stored state, the lower part of the main body part 1 is fitted into the drain port 32 and is further received by the bottom wall 22b of the rubber tray 30, so that the lower part of the main body part 1 is well prevented from sliding. it can. Further, since the electric razor in the storage state is stored at the lowest position of the sterilization drying apparatus, the overall height can be reduced, and the storage space can be reduced accordingly.

  When charging the secondary battery 6, as shown in FIG. 11, the lower end of the main body 1 is inserted into the connector portion 38 of the charging portion 23, the plug 9 is connected to the terminal plate 40, and the entire electric shaver.

In this state, the battery 6 can be charged by supplying the charging current output from the charging circuit provided on the control board 68 to the secondary battery 6 through the plug 9. At this time, the progress of charging can be displayed by turning on the LED display 8 provided in the main body 1. In a state where the electric razor plug 9 is connected to the connector portion 38, the lower portion of the main body portion 1 is lifted away from the base portion 37. Therefore, even if water or water droplets adhering to the main body portion 1 flow down to the base portion 37, the plug 9 does not get wet and can be charged safely.

  After drying the beard with an electric razor and then drying and disinfecting the razor head 2 that has been washed and washed, the entire razor head 2 is turned upside down and the razor head 2 is loaded as shown in FIG. The unit 21 is loaded. In the state where the razor head 2 is loaded in the head loading section 21, the front surface thereof is received by the positioning ribs 31 and 36, and the outer blade 3 is received by the window plate 35 as shown in FIG. 1. In addition, since the rear surface of the accommodating portion 10 is received at two upper and lower portions of the seat wall 47 and the protruding end of the accommodating portion 10 is received by the receiving step portion 42, the electric razor in the inverted posture is always in a constant posture. And can be supported in a stable state. In this loading process, the switch lever 92 is pushed down by the accommodating portion 10 and the switch element 93 switches the power feeding circuit to the energized state.

  When the razor head 2 is loaded into the head loading unit 21, the cleaning water that has entered the razor head 2 flows out to the bottom wall 21 b side of the head loading unit 21 through the outer blade 3. However, since the entire bottom wall 21 b is inclined downward toward the drain port 32, the wash water flowing out from the outer blade 3 flows down to the drain port 32, and from the drain port 32 to the drain pan 27. It falls to the part 84. At this time, the washing water inside the razor head 2 can be effectively discharged by turning on the switch button 7 of the main body 1 to idle the inner blade 4 for a predetermined time.

  By pressing the start switch 51 and turning on the switch element 69 in the above state, the axial fan 24 and the heater unit 25 are started, the sterilization LED 26 is turned on, and the sterilization drying operation can be started. . At this time, as shown in FIG. 13, the control circuit receives detection signals from the temperature sensor 78 and the switch element 93 and controls the operating state of each device.

  Hereinafter, the start timing and stop timing of each device will be described with reference to the timing chart shown in FIG. When the start switch 51 is turned on, the control circuit first turns on the switch illumination LED 70 on condition that the switch element 93 is switched on by the switch lever 92. The LED 70 is a pilot lamp that indicates that each device is in an operating state. When the LED 70 is turned on, it can be known that the sterilization drying apparatus is in an operating state. At the same time, the detection signal of the environmental temperature of the temperature sensor 78 is compared with a preset temperature condition, and the processing time for sterilization drying is set according to the environmental temperature. For example, if the environmental temperature is 15 ° C. or higher, the processing time is set to 80 minutes + 10 minutes + 5 minutes, and if the environmental temperature is less than 15 ° C., the processing time is set to 170 minutes + 10 minutes + 5 minutes. The reference environmental temperature need not be 15 ° C., and the sterilization drying treatment time can be appropriately set based on a plurality of environmental temperatures such as 10 ° C., 20 ° C., and 30 ° C.

  After waiting for the processing time for sterilization and drying to be set (after 0.05 seconds), the driving current is supplied to the heater unit 25 and the sterilization LED 26 to start the sterilization drying process in the previous stage. The sterilization drying process by the heater unit 25 and the sterilization LED 26 is continued for 30 minutes from the start. In the meantime, the outer blade 3, the inner blade 4, and the outer blade holder 11 that supports the outer blade 3 are heated to 65 ° C. by conduction heat and radiant heat from the heat transfer wall 34 and the window plate 35 to evaporate water droplets. be able to. At the same time, ultraviolet rays can be irradiated from the six sterilization LEDs 26 to sterilize germs attached to the outer blade 3, the inner blade 4, the outer blade holder 11, and the like.

  When 30 minutes have passed since the start of the sterilization drying, the axial fan 24 is activated and the drying air is supplied to the head loading unit 21 to perform the sterilization drying process in the middle stage. As shown in FIGS. 1 and 8, the dry air (pressurized air) delivered from the axial fan 24 is formed between the bottom wall 22 b on the tray 22 and the bottom wall 88 of the base body 17. After being fed to the gap between them and guided to flow forward by the guide rib 62 provided in this gap, it enters from the drain port 32 into the recess of the head loading section 21 and contacts the surface of the razor head 2 to the outside. Water droplets adhering to the blade 3, the inner blade 4, and the outer blade holder 11 are evaporated. Further, water vapor evaporated around the razor head 2 is discharged upward from between the positioning ribs 31 and 36 by dry air that blows through a gap between the razor head 2 and the window plate 35. At this time, the surface temperatures of the outer blade 3, the inner blade 4, and the outer blade holder 11 are cooled to about 45 ° C. by being cooled by the drying air when the environmental temperature is 20 ° C.

  In the middle sterilization drying process, water droplets adhering to the inner and outer surfaces of the razor head 2 are more effectively evaporated and dried by the heat transfer action of the heater unit 25 and the blowing action of the axial fan 24. Can do. In parallel with the heat transfer action by the heater unit 25, the outer blade 3 and the inner blade 4 are irradiated with ultraviolet light from the sterilization LED 26 and adhered to the outer blade 3, the inner blade 4, and the outer blade holder 11. Various germs can be sterilized, or germs contained in water droplets can be sterilized. Part of the wastewater stored in the drainage pan 27 evaporates by being exposed to the drying air in the course of performing the sterilization drying treatment in the middle stage, and is discharged out of the apparatus together with the drying air.

  When a predetermined time (80 minutes or 170 minutes) elapses after the start switch 51 is turned on, the axial fan 24 is stopped, and the subsequent sterilization drying process is performed for 10 minutes using only the heater unit 25 and the sterilization LED 26. In this process, the outer blade 3, the inner blade 4, and the outer blade holder 11 are heated to 65 ° C. as in the previous sterilization drying process. Therefore, at the time when the subsequent sterilization drying process is completed, the inner and outer surfaces of the razor head 2 can be reliably dried to a sanitary state. In the case of performing the subsequent sterilization drying process, the output of the sheathed heater 76 is set high so that the outer blade 3, the inner blade 4, the outer blade holder 11 and the like are removed during the previous or middle sterilization drying process. The heating temperature (80 ° C.) can be higher than the heating temperature (65 ° C.).

  When the subsequent sterilization drying process is completed, the operation of the heater unit 25 and the sterilization LED 26 is stopped, the axial fan 24 is started again, and the cooling process is started. The cooling process by the axial fan 24 is continued for 5 minutes from the start, and when 5 minutes have elapsed, the axial fan 24 is stopped, the switch illumination LED 70 is turned off, and all the sterilization drying processes are completed.

  The control circuit of the sterilization drying apparatus configured as described above is configured to drive the heater unit 25 prior to the activation of the axial fan 24 and to activate the axial fan 24 after a predetermined time has elapsed. It is. Thus, the razor head 2 is sterilized and dried only by the heat of the heater unit 25 prior to the start of the axial fan 24, and then the heat of the heater unit 25 and the drying air supplied from the axial fan 24 are The bacteria can be sterilized and dried by interaction.

  In addition, the control circuit is configured to drive the heater unit 25 and the axial fan 24 and stop the axial fan 24 after a predetermined time has elapsed. In this case, drying and sterilization can be performed again only with the heat of the heater unit 25. Further, the control circuit is configured to stop the driving of the heater unit 25 and start the axial fan 24 when the sterilization / drying process is completed, whereby the razor head is configured after the sterilization / drying process. 2 can be cooled with dry air at room temperature.

Reference numeral 96 denotes a torsion coil spring that urges the head loading portion 21 to turn toward the sterilization and drying posture. An axial fan 24 for supplying dry air to the razor head 2 is disposed inside the housing 15 below the shaft 95. Also in this embodiment, six sterilization LEDs 26 are arranged inside the sheathed heater 76 arranged in a ring shape.

  The charging unit 23 includes a base portion 37 that is recessed in the base portion, a connector portion 38 that bulges on the base portion 37, and a peripheral wall 39 that supports the front and rear surfaces of the lower portion of the main body portion 1. The same members as those described with reference to FIGS. 1 to 12 are denoted by the same reference numerals, and description thereof is omitted.

  The razor head 2 can maintain the interior of the fuzz chamber in a more sanitary state by forming a photocatalytic film on the surface of its component parts. Specifically, by forming a photocatalytic film on each of the outer blade 3, the inner blade 4, the outer blade holder 11, and the inner peripheral surface of the fluff chamber, the organic matter contained in sebum and sweat is photocatalyzed. It can be decomposed by the film to prevent the generation of off-flavors due to the decomposition of organic matter.

  The photocatalyst film is made of a film containing any one photocatalyst material of titanium oxide, cadmium sulfide, zinc sulfide, niobium, and ferric oxide, and is formed by sputtering, vapor deposition, CVD method, PVD method, electrodeposition method, or coating. Can be formed. When a photocatalyst material is applied to the inner blade 4 or the outer blade 3 to form a photocatalyst film, for example, a photocatalyst inorganic coating material obtained by mixing a titanium oxide sol, an inorganic coating material, and a curing catalyst is applied, Or by applying heat of several hundred degrees to cure. The titanium oxide is preferably anatase crystalline titanium dioxide, but may be rutile titanium dioxide metallized with copper, silver, platinum, or other metals. In addition, as a means for applying the suspension containing the photocatalyst material, a dip method, a spray method, electrostatic printing, inkjet, tampo printing, spin coating, or the like can be applied.

  Said photocatalyst film | membrane is activated by irradiating near ultraviolet light, and exhibits an organic substance decomposition | disassembly effect | action. Accordingly, if some of the sterilization LEDs 26 can emit near-ultraviolet light having a wavelength of 350 to 370 nm, the photocatalyst film is simultaneously sterilized with germs and sebum adhering to the hair and sebum with near-ultraviolet light. Can be activated to decompose organic matter. Since most of the inner peripheral wall of the fuzz chamber is occupied by the plastic-molded outer blade holder 11 and the head frame, photocatalyst particles are mixed into the molding material instead of forming a photocatalyst film. Then, the organic matter decomposition action may be exhibited.
