Description

  The present invention relates to a cleaning device for an electric razor that cleans hair chips, sebum, and the like adhering to a sliding contact surface of an inner blade or an outer blade while jetting and supplying a cleaning liquid to a razor head.

  This type of cleaning device is known from US Pat. In this case, the electric razor is loaded in a recumbent posture on the table, and the cleaning liquid is blown out and supplied to the entire upper surface of the razor head with a flat nozzle, and then the razor head is cleaned while driving the inner blade. This type of so-called flushing type cleaning device can always clean the outer and inner blades with the cleaning liquid after being filtered. After the cleaning is completed, the razor head can be dried by the drying air sent from the fan.

  Patent Document 2 discloses a so-called immersion cleaning type cleaning device in which an electric razor is held in an inverted posture and cleaned while the razor head is immersed in a cleaning tank. In any case, the secondary battery inside the electric shaver can be charged simultaneously with cleaning.

JP 2005-526562 A (paragraph number 0029, FIG. 1) JP-A-8-1117016 (paragraph number 0045, FIG. 6)

  According to the cleaning device of Patent Document 2, since cleaning is performed in a state where the cleaning tank is always filled with the cleaning liquid, it is necessary to store a large amount of cleaning liquid. During cleaning, the dust and sebum in the cleaning tank are agitated by the water flow generated by the inner blade drive, so cleaning is performed with dirty cleaning liquid, and the cleaning effect is reduced by that much, resulting in longer cleaning time. Cost. There is also the disadvantage that it puts a heavy burden on the filter.

  In this regard, the cleaning device of Patent Document 1 performs cleaning while blowing and supplying cleaning liquid with a flat nozzle, so that the amount of cleaning liquid stored can be reduced and the entire apparatus can be made compact. Further, since the cleaning is performed with a clean cleaning liquid after being filtered, the inside of the razor head can be effectively cleaned in a short time.

  However, since cleaning is performed while blowing and supplying the cleaning liquid to the entire upper surface of the razor head with a flat nozzle, the cleaning liquid cannot be effectively fed into the razor head. In addition, it is unavoidable that a part of the cleaning liquid flows down along the head surface without entering the razor head, and therefore, the cleaning liquid blown from the flat nozzle is wasted.

  SUMMARY OF THE INVENTION An object of the present invention is to provide a cleaning device capable of effectively cleaning the inside of a razor head by forcibly ejecting a cleaning liquid into the razor head. The object of the present invention is to provide a cleaning device in which the cleaning liquid is jetted and supplied to the razor head, while the cleaning liquid is effectively fed into the razor head and the razor head is effectively cleaned in a short time. Another object of the present invention is to provide a cleaning device that can be efficiently cleaned and that can efficiently clean the razor head while suppressing wasteful consumption of the cleaning liquid.

  In the cleaning device of the present invention, a tank 12 that stores cleaning liquid, a pump 13 that pressurizes and feeds the cleaning liquid in the tank 12, and a cleaning liquid fed from the pump 13 to the razor head. There are provided a nozzle 14 for blowing out and a fan 15 for feeding dry air. Above and below the housing 11, there are provided a cleaning chamber 20 and a liquid receiving chamber 21 for receiving the cleaning liquid after cleaning. A loading portion 22 that supports the electric razor in a state where the razor head 2 enters the cleaning chamber 20 is provided on the upper portion of the housing 11. Thus, the nozzle 14 has a feature in that the ejection direction of the nozzle 14 is directed toward the sliding contact area of the outer cutter 3 provided in the razor head 2.

  In a state where the electric razor is loaded in the loading unit 22, the loading unit 22 is formed so that the central axis of the razor head 2 is inclined obliquely downward. In this case, the inclination angle of the central axis of the razor head 2 is preferably set within a range of 25 to 65 degrees.

  The jet port 14a of the nozzle 14 is below the imaginary line M1 in contact with the lower surface of the protruding end of the razor head 2 of the electric razor loaded in the loading unit 22, and is orthogonal to the imaginary line M1 and in contact with the protruding end side surface of the razor head 2. It is located outside the line M2.

  A liquid recovery structure for recovering the cleaning liquid after cleaning and a tank 12 for storing the cleaning liquid are provided above and below the liquid receiving chamber 21.

  The liquid recovery structure includes a container-shaped liquid receiver 25 having an upper surface opened. The liquid receiver 25 is formed in a tapered shape from the upper surface opening toward the lower end side, and a drain port 27 is formed at the lower end portion.

  Above the drain 27 of the liquid receiver 25, a filter body 26 that filters cleaning residues such as hair chips and sebum is disposed. The filter body 26 is detachably attached to the liquid receiver 25.

  A cleaning solute 28 for cleaning liquid is disposed between the drain 27 of the liquid receiver 25 and the filter body 26.

  A tank 12 and a liquid receiver 25 detachably mounted on the upper surface of the tank 12 are provided so as to be freely inserted into and removed from the liquid receiving chamber 21. A suction port 24 of the pump 13 is provided facing the liquid receiving chamber 21, and a check valve 34 is disposed at the liquid supply port 33 of the tank 12 connected to the suction port 24. In the state where the liquid supply port 33 is connected to the suction port 24, a valve opening tool 36 for opening the check valve 34 is provided in the suction port 24.

  Both the base axis P1 of the nozzle 14 and the central axis P2 of the razor head 2 are arranged on substantially the same straight line, and the jetting center of the cleaning liquid jetted from the jetting port 14a of the nozzle 14 has an arched cross section. It is directed to the arch center of the outer blade 3.

  A fan 15 for supplying dry air is provided inside the housing 11. The lateral width B1 of the nozzle 14 is formed to be substantially the same width as the lateral width B2 of the outer blade 3, and the ejection port 14a is opened along the width direction. The nozzle 14 also serves as a guide 49 for feeding and guiding the drying air sent from the fan 15 toward the sliding contact surface of the outer blade 3.

  A front-stage liquid guide 23 that guides the cleaning liquid flowing down from the razor head 2 toward the liquid receiver 25 is disposed above the liquid receiver 25. The opening surface of the front liquid guide 23 is formed to be slightly smaller than the upper opening surface of the liquid receiver 25. The front-stage liquid guide 23 can be configured as an independent part.

  A connector 44 for supplying a current or an electric signal from the housing 11 side to the electric razor is provided between the electric razor and the receiving base 40 of the loading portion 22 that supports the electric razor. A protrusion 46 for increasing the contact pressure of the connector 44 is provided on the cradle 40.

  The loading unit 22 includes a receiving table 40 and a regulation wall 41 facing the receiving table 40. The interval between the cradle 40 and the regulating wall 41 is set to be gradually smaller as it goes from the loading port to the inner depth. A connector 44 for supplying a current or an electric signal from the housing 11 side to the electric razor is provided between the electric razor and the inner side of the regulation wall 41.

  In the present invention, in the cleaning device that supplies the cleaning liquid pressurized by the pump 13 toward the razor head 2 with the nozzle 14, the cleaning chamber 20 and the liquid receiving chamber 21 are provided above and below the housing 11. A loading portion 22 that supports the razor is provided at the top of the housing 11. In addition, the nozzle 14 is directed toward the razor head 2 entering the cleaning chamber 20 toward the sliding contact area of the outer blade 3 provided on the razor head 2, and the cleaning liquid ejected from the nozzle 14 is used as the outer blade. The razor head 2 can be forcibly fed through the three blade holes.

  Therefore, according to the cleaning device of the present invention, the cleaning liquid can be fed into the razor head 2 more reliably and without waste as compared with the conventional washing type cleaning device. The inside of the razor head 2 as well as the outer blade 3 and the inner blade 4 can be effectively cleaned in a short time. There is also an advantage that the razor head 2 can be efficiently cleaned by suppressing unnecessary consumption of the cleaning liquid.

  In the state where the electric razor is loaded in the loading unit 22, the cleaning device that forms the loading unit 22 so that the central axis of the razor head 2 is inclined obliquely downward is more reliable and less wasteful. Since the cleaning liquid after washing is allowed to flow down and discharged by the action of gravity while being fed into the razor head 2, the cleaning residue such as debris and sebum can be removed from the razor head 2 together with the cleaning liquid. In addition, the cleaning liquid after cleaning can be prevented from flowing along the surface of the main body 1.

  A hypothetical line that is perpendicular to the virtual line M1 and is in contact with the side surface of the razor head 2 is below the imaginary line M1 that is in contact with the bottom surface of the razor head 2 of the electric razor. According to the cleaning device positioned on the outer side of M2, the jet nozzle 14a of the nozzle 14 can be positioned outside the flow range of the cleaning liquid after cleaning that flows down from the razor head 2. Therefore, it is possible to reliably supply the cleaning liquid to the razor head 2 while reliably preventing the cleaned cleaning liquid dripping from the razor head 2 from falling on the nozzle 14.

  According to the cleaning device provided with the liquid recovery structure for recovering the cleaning liquid after cleaning and the tank 12 for storing the cleaning liquid on the upper and lower sides of the liquid receiving chamber 21, the cleaning liquid scattered in the cleaning chamber 20 is liquid. Since it can be collected and returned to the tank 12 by the recovery structure, the cleaning liquid can be used repeatedly in a cyclic manner without waste.

  When the container-like liquid receiver 25 constituting the liquid recovery structure is formed in a concentric shape downward from the upper surface opening toward the lower end side, and the drainage port 27 is formed in the lower end portion, the cleaning dripping from the cleaning chamber 20 is performed. The liquid can be quickly flowed down and guided by the liquid receiver 25 to prevent the cleaning liquid from staying in the liquid recovery structure, and the circulation rate of the cleaning liquid can be improved correspondingly, and the amount of cleaning liquid stored in the tank 12 can be reduced. Less.

  When the filter body 26 that filters above the drainage port 27 is disposed, the cleaning residue such as flakes and sebum flowing down from the cleaning chamber 20 together with the cleaning liquid is filtered by the filter body 26, and only the cleaning liquid after filtration is filtered. Since it can be returned to the tank 12, it is possible to prevent cleaning residues such as fluff and sebum from accumulating on the bottom of the tank 12, and to maintain the cleaning liquid sucked into the pump 13 in a clean state. In addition, the performance can be well prevented from being deteriorated by the cleaning residue. Since the cleaning liquid after being filtered can always be jetted and supplied to the razor head 2, there is also an advantage that the cleaning effect can be improved. When the filter body 26 is detachably attached to the liquid receiver 25, it is possible to easily clean and replace the filter body 26 that is easily soiled, and to reduce the maintenance work of the cleaning device.

  According to the cleaning device in which the cleaning solute 28 of the cleaning liquid is disposed between the drainage port 27 and the filter body 26, the cleaning solute 28 is brought into contact with the cleaning liquid refluxed from the liquid receiver 25 to the tank 12. The cleaning liquid can be replenished, and the cleaning power of the cleaning liquid can be kept constant, so that the inside of the razor head 2 can be properly cleaned in a shorter time.

  When the tank 12 and the liquid receiver 25 detachably mounted on the upper surface of the tank 12 are provided so as to be freely inserted into and removed from the liquid receiving chamber 21, the tank 12 and the liquid receiver 25 are removed from the housing 11. Since the tank 12 can be cleaned or replenished with a new cleaning liquid, operations such as cleaning the tank 12, cleaning and replacing the filter 26 provided in the liquid receiver 25, and replenishing the washing solute 28 can be performed more easily. Can do.

  When the tank 12 is loaded in the liquid receiving chamber 21 and the liquid supply port 33 is connected to the suction port 24 of the pump 13, the check valve 34 provided in the liquid supply port 33 is opened by the valve opening tool 36. If it can be operated, the liquid supply port 33 can be connected to the suction port 24 simply by loading the tank 12 into the liquid receiving chamber 21, and the pump 13 can be operated. As compared with the embodiment in which the suction passage such as the above is immersed in the tank 12 and the cleaning liquid is sucked by the pump 13, the mounting and removing operations of the tank 12 with respect to the housing 11 can be simplified.

  Both the base axis P1 of the nozzle 14 and the center axis P2 of the razor head 2 are arranged on substantially the same straight line, and the jetting center of the cleaning liquid jetted from the jetting port 14a of the nozzle 14 has an arch-shaped outer surface. According to the cleaning device that directs toward the arch center of the blade 3, the cleaning liquid is more effectively fed into the interior of the razor head 2 through the blade holes of the outer blade 3 that are centrally arranged near the arch center. It is possible to more effectively clean the outer blade 3 and the inner blade 4 to which scraps and sebum easily adhere, and the sliding contact surfaces of both. When two sets of outer blades 3 and inner blades 4 are arranged adjacent to the razor head 2, the jet nozzles 14 a are arranged facing the outer blades 3, so that the adjacent outer blades 3 and inner blades 2 are arranged facing each other. The cleaning liquid can be reliably supplied to each of the blades 4 and can be cleaned accurately.

  The lateral width B2 of the outer blade 3 and the lateral width B1 of the nozzle 14 are formed to be substantially the same width, and the nozzle 14 also serves as a guide 49 for feeding and guiding the drying air sent from the fan 15 toward the sliding contact surface of the outer blade 3. By doing so, it is possible to effectively dry the razor head 2 in a short time by effectively supplying the drying air. This is because the nozzle 14 protrudes toward the razor head 2 in a state of facing the outer blade 3, so that by supplying the drying air along the nozzle 14, the razor head is prevented from diffusing the drying air. This is because it can be delivered accurately toward 2. Further, the number of parts can be reduced as compared with the case where the guide 49 is separately provided, and the structure of the cleaning device can be simplified and the cost can be reduced accordingly. There is also an advantage that the cleaning liquid adhering to the jet nozzle 14a is dried by the drying air, so that the nozzle 14 can be kept in a hygienic state when not in use.

  An upstream liquid guide 23 having an opening slightly smaller than the upper opening surface of the liquid receiver 25 is disposed above the liquid receiver 25, and the cleaning liquid flowing down from the cleaning chamber 20 and the razor head 2 is received by the upstream liquid guide 23. By guiding the flow down to 25, it is possible to more reliably prevent the cleaned cleaning liquid from flowing out of the liquid receiver 25, and the entire amount of the cleaning liquid can be collected in the tank 12. The liquid receiving chamber 21 is not soiled by the cleaning liquid flowing down from the cleaning chamber 20.

  A connector 44 for supplying a current or an electric signal from the housing 11 side to the electric razor is provided between the electric razor and the receiving base 40 of the loading portion 22 that supports the electric razor, and a protrusion 46 is provided on the receiving base 40. If the contact pressure of the connector 44 can be increased, the contact state between the contact terminals 44a and 44b of the connector 44 can be ensured only by loading the electric razor into the loading portion 22, and the operating state of the electric razor during cleaning. Can always be properly controlled.

  The loading unit 22 is configured to include the receiving table 40 and the regulating wall 41 facing the receiving table 40, and the facing distance between the receiving table 40 and the regulating wall 41 is gradually decreased from the loading port toward the inner depth. In addition, when a connector 44 for supplying an electric current or an electric signal from the housing 11 side to the electric razor is provided between the electric razor and the inner side of the regulation wall 41, the electric razor is inserted into the loading portion 22 and loaded. As a result, the main body 1 is brought into close contact with the regulating wall 41, and the contact between the electric razor and the contact terminals 44a and 44b of the connector 44 provided on the regulating wall 41 can be ensured, and the operating state of the electric razor during cleaning Can always be properly controlled.

Reference numeral 6 is a secondary battery, 7 is an LED for display, and 8 is a slide knob for switching the main switch. The inner blade 4 may be a rotary rotary blade.

  The cleaning device includes a tank 12 that stores cleaning liquid, a pump 13 that pressurizes and supplies the cleaning liquid in the tank 12, and a razor head that supplies the cleaning liquid supplied from the pump 13 in a rectangular box-shaped housing 11. Nozzle 14 that blows out toward the nozzle 2 and a fan 15 that feeds dry air are arranged. A cleaning chamber 20 and a liquid receiving chamber 21 for receiving the cleaning liquid after cleaning are provided above and below the housing 11, and a loading unit 22 that supports an electric razor is provided on the upper surface side of the housing 11. It is provided in a state of communicating with.

  The cleaning chamber 20 is an oblique space that opens slightly toward the liquid receiving chamber 21 and has a width slightly larger than the width of the razor head 2, and the nozzle 14 is disposed on the peripheral wall facing the razor head 2. A front-stage liquid guide 23 that guides the cleaning liquid flowing down along the peripheral wall of the cleaning chamber 20 is formed in a circular shape integrally with the peripheral wall of the cleaning chamber 20 at the lower surface opening of the cleaning chamber 20. The liquid receiving chamber 21 is a rectangular parallelepiped space opened on one side surface of the housing 11, and a suction port 24 of the pump 13 is opened at the lower end of the rear end. Inside the liquid receiving chamber 21, a liquid recovery structure for recovering the cleaning liquid after cleaning and a tank 12 for storing the cleaning liquid are accommodated in a freely removable manner.

  The liquid recovery structure has a mortar-shaped liquid receiver 25 that is open at the upper surface and is formed in a constricted shape toward the lower end side, and filters cleaning residues such as debris and sebum contained in the cleaning liquid after cleaning. The filter body 26 to be configured. A surfactant (cleaning solute) 28 is disposed between the drainage port 27 opened at the lower end of the liquid receiver 25 and the filter body 26. The filter body 26 is made of a filter medium such as a nonwoven fabric, filter paper, fiber mat, or open-cell porous mat, and is fixed to a shape retaining frame with one or more filter mediums stacked. It is configured and is detachably attached to a receiving portion 29 formed in a recess in the liquid receiver 25.

  The surfactant 28 is made of, for example, solid soap, and is accommodated in a recess 30 that is continuous with the drainage port 27. In the case where the cleaning liquid contains water as a main component, the cleaning solute may include a bactericide, a defoaming agent, a lubricant and the like in addition to the surfactant. When alcohol is the main component of the cleaning liquid, the surfactant 28 is not used.

  The tank 12 is formed of a rectangular box-like box having an upper surface opened, and an opening peripheral wall of the liquid receiver 25 is detachably fitted to the upper surface opening. A liquid supply port 33 that is fitted and connected to the suction port 24 is formed at the lower end of the side wall of the tank 12 that faces the suction port 24 of the pump 13. Inside the tank 12, a ball-like check valve 34 for closing the liquid supply port 33 and a spring 35 for closing and energizing the check valve 34 are arranged. As shown in FIG. 1, the check valve 34 is opened by a release pin (valve opener) 36 provided in the suction port 24 only when the liquid supply port 33 is connected to the suction port 24, and the tank The inside and the suction port 24 are communicated. The suction port 24 is provided with a ring-shaped packing 38 for preventing liquid leakage. The tank 12 and the liquid receiving body 25 can be freely taken in and out of the liquid receiving chamber 21, and for this purpose, a handle 37 is provided on the outer surface of the tank 12.

  The front liquid guide 23, the liquid receiver 25, and the tank 12 are similar in shape when viewed from the plane, and have a similar relationship, and the cleaning liquid that flows down along the peripheral wall of the cleaning chamber 20 is reliably transferred to the liquid receiver 25. In order to flow down, only the front liquid guide 23 is formed to be slightly smaller than the other two members 12 and 25. That is, the opening surface of the front liquid guide 23 is formed slightly smaller than the upper opening surface of the liquid receiver 25. The front-stage liquid guide 23 can be configured as an independent part. In this case, the front-stage liquid guide 23 may be press-fitted and fixed to the lower surface opening of the cleaning chamber 20.

  The loading unit 22 is a cylindrical wall that surrounds a space having a rectangular cross section with a lower receiving base 40 that supports the electric razor, an upper regulating wall 41 that faces the receiving base 40, and a pair of side walls that connect the two. It is configured in the shape. The cradle 40 and the regulation wall 41 are formed obliquely so as to be inclined downward toward the cleaning chamber 20 and can support the electric razor obliquely downward with respect to the horizontal plane. The interval between the cradle 40 and the regulation wall 41 is set to be gradually smaller from the loading port side toward the inner depth.

  The inclination angle of the central axis P2 of the razor head 2 loaded in the loading unit 22 can be set within a range of 25 to 65 degrees. In this embodiment, the inclination angle of the central axis P2 is 45 degrees. Here, the central axis P2 of the razor head 2 is assumed to be a virtual plane that passes through the top of the arch of the adjacent outer blade 3, and a virtual axis that is orthogonal to the virtual plane and passes through the center of the adjacent portion of the two outer blades 3. Means. Note that if the inclination angle of the central axis P2 is smaller than 25 degrees, the left and right width dimensions of the housing 11 cannot be avoided, and there is a disadvantage that dead space increases. Further, if the tilt angle of the central axis P2 exceeds 65 degrees, the cleaning liquid sprayed and supplied from the nozzle 14 toward the outer blade 3 interferes with the cleaning liquid after the cleaning flowing down from the outer blade 3, so that the cleaning liquid is It cannot be effectively supplied to the inside of the outer blade 3.

  As shown in FIG. 6, the lateral width B <b> 1 of the nozzle 14 is slightly wider than the lateral width B <b> 2 of the outer blade 3. On the end face of the nozzle 14 facing the pair of adjacent outer blades 3, 3, a group of jet holes 14 a made of a single hole is provided in a state of forming a straight line up and down. The thickness dimension C1 of the nozzle 14 is set to be slightly smaller than the thickness dimension C2 of the outer cutter 3, and the lateral width between both side ends of the jet nozzle 14a is set to be slightly smaller than the lateral width B2 of the outer cutter 3. In any case, since the cleaning liquid ejected from the ejection port 14a reaches the outer blade 3 while spreading in a conical shape, the cleaning liquid can be sprayed and supplied to the entire outer surface of the outer blade 3. The adjacent interval between the arch centers of the outer blades 3 and the adjacent interval between the centers of the jet ports 14a constituting the upper and lower straight lines are set to be the same. The nozzle 14 and the pump 13 communicate with each other via a passage 16.

  In the middle of the passage 16 near the nozzle 14, an ion elution unit 17 is provided for eluting metal ions into the cleaning liquid. Inside the ion elution unit 17, a pair of metal electrodes 18 are opposed to each other in contact with the cleaning liquid, and by supplying an elution current to these metal electrodes 18, metal ions are eluted in the cleaning liquid. be able to. The metal electrode 18 is made of silver or copper. In the former case, silver ions are eluted, and in the latter case, copper ions are eluted. Silver ions or copper ions eluted in the cleaning liquid adhere to the surfaces of the outer blade 3 and the inner blade 4, and the antibacterial action prevents the growth of various bacteria and can prevent the generation of off-flavors.

  As shown in FIG. 3, the jet nozzle 14 a of the nozzle 14 is below an imaginary line M <b> 1 in contact with the lower surface of the protruding end of the razor head 2 of the electric razor loaded in the loading unit 22, and from an imaginary line M <b> 2 in contact with the protruding end side surface of the razor head 2. It is located outside. Further, both the base axis P1 of the nozzle 14 and the center axis P2 of the razor head 2 are arranged on the same straight line, and furthermore, the ejection center of the cleaning liquid ejected from the ejection port 14a of the nozzle 14 is The outer edge 3 having an arched cross section is oriented toward the arch center. By disposing the nozzle 14 in this manner, the cleaning liquid is effectively passed into the razor head 2 while preventing the mutual interference between the cleaning liquid ejected from the nozzle 14 and the cleaning liquid that has flowed down from the outer blade 3. Can be supplied to.

  A connector 44 for supplying a drive current or an electric signal from the housing 11 side toward the electric razor is provided between the inner side of the receiving base 40 of the loading unit 22 and the electric razor, and is provided on the outer surface of the housing. By turning on the provided control switch 45, as shown in the timing chart shown in FIG. 5, while the pump 13 is driven and the inside of the razor head 2 is cleaned, the motor 5 is activated and the inner blade 4 can be driven. The driving speed of the inner blade 4 at this time is the same as the driving speed during shaving. The connector 44 includes a contact terminal 44a provided on the receiving base 40 side and a contact terminal 44b provided on the main body 1 side. In order to increase the contact pressure of both contact terminals 44a and 44b and to connect both 44a and 44b more reliably, a protrusion 46 is provided near the loading port of the cradle 40.

  The fan 15 is a centrifugal fan and is accommodated in a fan chamber 47 provided in the upper part of the cleaning chamber 20. The drying air delivered from the fan 15 is supplied to the fan chamber 47 through a passage 48 that is continuous, and is further guided by a guide 49 provided integrally with the upper portion of the nozzle 14 continuously to the end of the passage 48. , Sprayed toward the razor head 2. The guide 49 is inclined in a state where it rises upward toward the intersection between the central axis P2 of the razor head 2 and the virtual plane passing through the arch top surfaces of the two outer blades 3 described above, and most of the drying wind is You can guide the direction towards the previous intersection. In this way, when the guide 49 is provided using the nozzle 14, the drying air can be effectively fed to the razor head 2 side along the nozzle 14 facing the outer blade 3. Can be effectively dried in a short time. As shown in the timing chart of FIG. 5, the fan 15 is automatically started after the supply of the cleaning liquid from the nozzle 14 is stopped, and is driven for a certain period of time. After the fan 15 stops, charging is performed by supplying a charging current to the secondary battery 6. The state of charge can be displayed by turning on the LED 7 provided in the main body 1.

  According to the cleaning apparatus configured as described above, the razor head 2 enters the cleaning chamber 20 as shown in FIG. Since the center and the jet outlet 14a of the nozzle 14 face each other, the cleaning liquid can be effectively supplied to the inside of the razor head 2, so that the inside of the razor head 2 can be effectively cleaned in a short time. In addition, the razor head 2 can be efficiently cleaned by suppressing wasteful consumption of the cleaning liquid as compared with a conventional cleaning apparatus that performs cleaning while blowing and supplying cleaning liquid to the entire upper surface of the razor head with a flat nozzle. .

  FIG. 7 shows another embodiment of the present invention. In this case, an ozone generator 52 is provided in the housing 11 so that ozone generated by the ozone generator 52 can be supplied to the razor head 2 together with the cleaning liquid. For this purpose, the ejector 54 is constituted by the nozzle 14 and the chamber 53 surrounding the nozzle 14, and the inside of the chamber 53 and the ozone generator 52 are communicated with each other through a passage 55. The ozone generator 52 can generate ozone by applying a boosted pulse current between the discharge electrodes to cause corona discharge, and cleaning is performed by the pulling action of the cleaning liquid ejected from the nozzle 14 at the outlet 56 of the chamber 53. It is fed to the razor head 2 together with the liquid. The ozone generator 52 can be replaced with a sterilizable ion generator.

  As described above, when ozone is supplied to the razor head 2 together with the cleaning liquid, the surfaces of the outer blade 3 and the inner blade 4 can be sterilized and deodorized by the oxidizing action of ozone, so that the razor head 2 has been cleaned. The rot odor remains and the inside of the razor head 2 can be maintained in a hygienic and clean state. In this embodiment, a heater 58 is disposed in the passage 48 for supplying the drying air so that the drying air can be heated as necessary.
