Description

  The present invention relates to an electric razor cleaning device that supplies cleaning liquid directly to the inside of a razor head and cleans hair chips and sebum adhering to a sliding contact surface of an inner blade and an outer blade.

  The electric razor cleaning device has a cleaning device (see Patent Document 1) that performs cleaning with the razor head immersed in the cleaning liquid stored in the cleaning tank, and pumps the cleaning liquid stored in the tank with a pump, A cleaning device (see Patent Document 2) that performs cleaning while continuously supplying to the upper surface of a razor head is known. In the former structure of the cleaning device, the cleaning liquid pumped up from the tank is continuously supplied to the cleaning tank. However, a cleaning device that discontinuously feeds the cleaning liquid by a pump has also been proposed (see Patent Document 3). .

Japanese Patent Laid-Open No. 8-117016 (paragraph number 0020, FIG. 1) JP 2005-526562 A (paragraph number 0029, FIG. 1) JP 2005-518851 A (paragraph numbers 0027 to 0028, FIG. 1)

  In the cleaning device of Patent Document 1, the inside of the razor head is cleaned while reciprocating the inner blade while the razor head is immersed in the cleaning liquid in the cleaning layer. Can clean sebum. However, since the cleaning liquid can only enter the inside of the razor head by a natural inflow action from the mesh of the outer blade or the like, the cleaning liquid in the razor head is not easily replaced. In addition, it takes time to discharge the shavings and sebum washed away by driving the inner blade to the outside of the razor head by the amount that the cleaning liquid is difficult to change.

  In that respect, the cleaning device of Patent Document 2 performs cleaning while continuously supplying the cleaning liquid to the upper surface of the razor head, so that the cleaning liquid filtered into the razor head can be constantly fed. However, not all of the continuously supplied cleaning liquid is supplied into the razor head, and it is inevitable that a part of the cleaning liquid flows down along the head surface without entering the razor head. There is only a waste. In addition, since the cleaning liquid in the razor head has no other action than flowing down from the outer blade, it takes time to discharge the chips and sebum out of the razor head as in the cleaning device of Patent Document 1.

  The object of the present invention is to supply the cleaning liquid pumped by the pump into the razor head without waste, and forcibly replace the cleaning liquid in the razor head. It is an object of the present invention to provide a cleaning device that can effectively remove a series of cleaning operations in a short period of time by effectively discharging the removed fluff and sebum together with the cleaning liquid to be discharged out of the razor head. The objective of this invention is providing the cleaning apparatus suitable for wash | cleaning and removing the sebum and fluff stuck to the inner blade of the rotary electric shaver.

  The cleaning device of the present invention includes a tank 19 for storing a cleaning liquid in a housing 16, a loading portion 21 for fixing and holding an electric razor in a cleaning position, and a head sink 22 for receiving an electric razor razor head 2 attached to the loading portion 21. And a pump 36 that pumps the cleaning liquid in the tank 19 to the nozzle 32 provided in the head sink 22. A liquid receiving opening 33 is formed in the peripheral wall of the razor head 2 facing the nozzle 32. Thus, the cleaning liquid delivered from the nozzle 32 is directly fed into the razor head 2 through the liquid receiving opening 33 for cleaning.

  A ventilation space S for introducing external air into the razor head is secured between the nozzle port 32a of the nozzle 32 and the liquid receiving opening 33.

  The opening area of the liquid receiving opening 33 is set to be larger than the opening area of the nozzle opening 32 a of the nozzle 32, and the tip of the nozzle 32 faces the internal space of the razor head 2 through the liquid receiving opening 33.

  The razor head 2 is provided with a shutter 35 that closes the liquid receiving opening 33 when the electric razor is used and opens the liquid receiving opening 33 during cleaning.

  The shutter 35 is opened when the electric razor is mounted on the loading unit 21 in a predetermined cleaning posture, and the shutter 35 is closed when the electric razor is removed from the loading unit 21.

  The shutter 35 for slidingly opening and closing the liquid receiving opening 33 is closed and biased by a shutter biasing body 52. In the process of mounting the electric razor on the loading unit 21 in a predetermined cleaning posture, the head sink 22 is provided with an opening device 55 that opens the shutter 35 against the urging force of the shutter urging body 52.

  A passive protrusion 52 that is received by the opening member 55 is provided at the closing start edge of the shutter 35.

  The head case 12 constituting the razor head 2 and the outer blade holder 13 which is detachably attached to the head case 12 divide a fuzz chamber R for storing the foul. The liquid receiving opening 33 is opened in the outer blade holder 13, and the shutter 35 is guided and supported by an inner wall 12 a and an outer wall 12 b provided in the head case 12 so as to be openable and slidable.

  The liquid receiving opening 33 and the shutter 35 are formed in a tapered shape from the open end side of the liquid receiving opening 33 toward the closed end side.

  A restriction step 51 for restricting the movement of the fuzz is formed along the inner edge of the liquid receiving opening 33.

  A lint pool 55 is formed between the closed end of the shutter 35 in the closed state and the closed end of the regulation step portion 51.

  In the present invention, in the cleaning device that performs cleaning while feeding the cleaning liquid to the razor head 2, the liquid receiving opening 33 is formed in the razor head 2 loaded in the head sink 22, and the head is faced to the liquid receiving opening 33. Since the cleaning liquid is fed directly from the nozzle 32 provided in the sink 22 to the inside of the razor head 2 through the liquid receiving opening 33, the cleaning liquid fed from the pump 36 can be washed without waste. By feeding the inside of the head 2, the inside of the outer blade 3, the inner blade 4, or the razor head 2 can be cleaned accurately. Further, since the cleaning liquid is directly fed into the razor head 2, the cleaning liquid in the razor head 2 can be forcibly replaced and always cleaned with a new cleaning liquid. Further, since the cleaning liquid is forcibly replaced, the dust and sebum washed off from the inner blade 4 and the outer blade 3 are effectively discharged together with the cleaning liquid discharged out of the razor head 2, and a series of Cleaning work can be performed effectively in a short time. In particular, in a rotary electric razor, dust and sebum easily accumulate on the inner corners of a group of spiral blades and a columnar blade blade constituting the inner blade 4, but this It is possible to provide a cleaning device suitable for reliably washing and removing sebum and hair chips.

  When the ventilation space S is secured between the nozzle port 32a of the nozzle 32 and the liquid receiving opening 33, external air is positively introduced into the razor head 2 and the cleaning liquid in the razor head is removed by the outer blade. 3 can be expelled, and when the outer blade 3 is clogged with chips and the cleaning liquid cannot be sufficiently discharged, the cleaning liquid is discharged from the ventilation space S and cleaned in the razor head 2. The liquid can be prevented from filling up. At the time of drying, dry air is introduced from the ventilation space S to promote replacement of air in the razor head 2, and the inner walls of the inner blade 4 and the outer blade 3 can be effectively dried.

  According to the cleaning device, the opening area of the liquid receiving opening 33 is set larger than the opening area of the nozzle opening 32 a of the nozzle 32, and the tip of the nozzle 32 faces the internal space of the razor head 2 through the liquid receiving opening 33. The cleaning liquid delivered from the nozzle 32 can be more reliably supplied into the razor head 2, and the cleaning liquid is directly sprayed toward the inner wall of the razor head 2 facing the nozzle 32 and the internal member. It can be replaced more effectively.

  If a shutter 35 is provided that closes the liquid receiving opening 33 when using an electric razor and opens the liquid receiving opening 33 during cleaning, the shutter 35 is closed so that the hair from the liquid receiving opening 33 is used when the electric razor is used. It is possible to reliably prevent debris from scattering, or to prevent foreign matter from entering the razor head 2 when the electric razor is not used. Further, at the time of cleaning, the cleaning liquid can be reliably fed into the razor head 2 by opening the shutter 35.

  The shutter 35 is opened when the electric razor is mounted on the loading unit 21 in a predetermined cleaning posture, and the shutter 35 is closed when the electric razor is removed from the loading unit 21. Since the shutter 35 can be opened and closed without having to bother the user's hand, for example, the electric shaver is washed with the shutter 35 closed or the shutter 35 is opened by the carelessness of the user. You can wipe out problems such as shaving.

  According to the cleaning device in which the shutter 35 can be opened by the release tool 55 against the urging force of the shutter urging body 52 in the process of mounting the electric razor on the loading unit 21 in a predetermined cleaning posture. Can be opened with the opening tool 57 and the liquid receiving opening 33 and the auxiliary opening 34 can be opened with certainty, so that the user himself can open and close the open / close state of the shutter 35. Without having to be aware of this, cleaning can always be performed properly.

  According to the shutter opening structure in which the passive protrusion 52 is provided at the closing start edge of the shutter 35 and the passive protrusion 52 is received and opened by the opening tool 55, the reciprocating area of the passive protrusion 52 when the shutter 35 is opened and closed is received. It can be located on the outer surface of the opening region of the liquid opening 33. Therefore, when the passive protrusion 52 is received by the opening tool 57 and the shutter 35 is opened, it is not necessary to separately provide an opening or a groove for releasing the passive protrusion 52, and the peripheral structure of the liquid receiving opening 33 is simplified accordingly. To make the impression of appearance clear.

  According to the shutter opening structure in which the liquid receiving opening 33 is opened in the outer blade holder 13 and the shutter 35 is slidably guided by the inner wall 12a and the outer wall 12b provided in the head case 12, the shutter 35 that is opened and closed is moved to the head case. The inner wall 12a and the outer wall 12b of the twelve can always slide and guide in a stable state, and the opening operation of the shutter 35 by the passive protrusion 52 and the closing operation of the shutter 35 by the shutter urging body 54 can always be performed smoothly. .

  When the liquid receiving opening 33 and the shutter 35 are formed in a tapered shape from the open end side to the closed end side of the liquid receiving opening 33, the right and left sliding surfaces are moved until just before the shutter 35 finishes moving to the closed position. A clearance is ensured between the moving portion and the opening edge of the liquid receiving opening 33 to avoid contact and sliding between the moving portion and the bristle sliding portion between the liquid receiving opening 33 and the shutter 35. It is possible to prevent clogging of scraps and to smoothly open and close the shutter 35. When the left and right sliding portions of the liquid receiving opening 33 and the shutter 35 are provided in parallel, the sliding portion is likely to become clogged and twisted when the shutter 35 is closed, and cannot be closed. . This is because there is no escape place for the hair adhering to the sliding portion.

  When the regulation step portion 51 is formed so as to protrude along the inner edge of the liquid receiving opening 33, the inner surface of the closing start end of the shutter 35 in the closed state is covered with the regulation step portion 51, so that the fluff in the fluff chamber R is removed from the shutter 35. It is possible to restrict entry into the closing start of the door. The dust does not leak from the closing start end of the shutter 35.

  When a fouling pool 55 is formed between the closed end of the shutter 35 in the closed state and the closed end of the restriction step portion 51, the closing start end of the shutter 35 in the closed state and the step on the closed end side of the restriction step portion 51. It is possible to eliminate the solidification caused by the fuzz between the parts. In other words, even if fouls may adhere to the fuzz pool 55, the foul will not be compressed and solidified at the closing start of the shutter 35. Can be easily swept away.

As shown in FIG. 4, the housing 16 includes a housing main body 16A that covers the outer surface of the main part of the cleaning device, and a housing base 16B that is fixed near the lower part of the inner surface of the housing main body 16A. A tank 19 for storing the cleaning liquid is disposed between the base 15 and the housing base 16B, and a pump 36 described later and a head sink 22 described later are assembled to the housing base 16B.

  In the upper center of the housing main body 16A, a loading portion 21 for fixing and holding the electric razor in a cleaning posture is formed in a recess, and a head sink 22 for continuously receiving the razor head 2 is provided at the lower end thereof. The control panel provided on the front shoulder of the housing main body 16A has a select button 23 for selecting an operation mode, a charge button 24 for starting charging, cleaning, drying, and charging states, and a reset state. An LED display unit 25 for displaying this is provided. In FIG. 2, reference numeral 20 denotes a viewing window for visually confirming the liquid level in the tank 19.

  As shown in FIGS. 3 and 4, the electric razor is inserted and mounted in the loading portion 21 in an inverted posture in which the back surface thereof faces the stereotaxic post 17, and three places on the front and rear surfaces of the main body portion 1 are the loading portion 21 and the head. The sink 22 is received and held, and the back portion in the vicinity of the power supply plug 11 is positioned and held by a holding projection 26 protruding from the top of the positioning post 17. A receiving portion of the main body 1 in the loading portion 21 and the head sink 22 is denoted by reference numeral 27. In the center of the front surface of the head sink 22, an axial-flow type air blowing fan 29 for supplying dry air to the razor head 2 after cleaning is disposed.

  As described above, the razor head 2 is supported in a suspended state inside the head sink 22 in a state where the electric razor is mounted on the loading portion 21. In order to perform cleaning by directly supplying the cleaning liquid into the razor head 2 in this state, a pump unit 31 is disposed inside the tank 19, and a nozzle 32 is provided on the inclined bottom wall of the head sink 22. Further, a liquid receiving opening 33 and auxiliary openings 34 are formed on the left and right of the peripheral wall of the razor head 2 facing the nozzle 32 so that the openings 33 and 34 can be opened and closed by a slidable shutter 35. The pump unit 31 is fixed to the housing base 16B, and a centrifugal pump (pump) 36 and a motor 37 that rotationally drives the centrifugal pump 36 are incorporated therein. The longitudinal outlet passage 38 of the centrifugal pump 36 and the inclined nozzle 32 are connected via a lateral passage 39.

  The tank 19 is formed in a box-like container shape, and a liquid supply port 42 for inserting the previous pump unit 31 on its upper surface and a reflux port for inserting a reflux tube 44 continuous with the drain tube 43 of the head sink 22. 45 (see FIG. 4). Inside the tank 19 facing the reflux port 45 in the vertical direction, a filter 47 that filters the cleaning liquid that flows down from the head sink 22 and that contains washed chips and sebum is disposed. The filter 47 is formed by a filter frame 47 a and a filter element 47 b that is formed in a W-shaped cross section by the filter frame 47 a, and is formed in a container shape that opens upward, and the upper opening edge is the upper wall of the tank 19. The position is held by a regulating rib 48 provided on the inner surface so that it can move only within a certain range. By providing the filter 47, the centrifugal pump 36 can pressurize the filtered cleaning liquid and feed it to the nozzle 32. The tank 19 and the filter 47 are made into a cartridge, and are replaced each time a predetermined usage time elapses.

  The cleaning liquid in the tank 19 is pressurized by the pump 36 and is supplied to the nozzle 32, and is blown out and supplied from the nozzle port 32 a at the tip of the nozzle 32 facing the liquid receiving opening 33 into the fluff chamber R. At this time, in order to attract air into the fluff chamber R together with the cleaning liquid to promote foaming, and to separate and clean the fluff and sebum stuck to each part by the bursting impact of the foam, A ventilation space S for introducing external air into the interior of the fluff chamber R is secured between the liquid receiving opening 33 (see FIG. 1). Specifically, the opening area of the liquid receiving opening 33 is set sufficiently larger than the opening area of the nozzle port 32 a of the nozzle 32 having a circular cross section, and the ventilation space S is formed between the both 32 and 33. .

  As shown in FIGS. 5 and 6, each of the liquid receiving opening 33 and the auxiliary opening 34 is formed in a tapered arch shape, and a regulation stage that holds the closing start end of the shutter 35 along the inner edge of the opening. The part 51 is formed in a protruding manner. The shutter 35 is formed in a tapered arch shape like the openings 33 and 34, and a passive protrusion 52 projects from the closing start edge (see FIG. 7). A spring seat 53 is integrally formed at the base end of the shutter 35, and the spring seat 53 is guided and supported by an inner wall 12a and an outer wall 12b provided on the head case 12 so as to be slidable. The entire shutter 35 is closed and biased by a compression coil type shutter spring (shutter biasing body) 54 accommodated therebetween. As described above, when the liquid receiving opening 33, the auxiliary opening 34, and the shutter 35 are each formed in a tapered arch shape, fouling bites into the sliding edges on both sides of the shutter 35 and the openings 33 and 34. Thus, the opening / closing operation of the shutter 35 can be smoothed. By providing the inner wall 12a, it is possible to prevent the dust inside the hair chamber R from entering between the inner and outer walls 12a and 12b.

  Since the shutter 35 is held in the closed state by the shutter spring 54, the liquid receiving opening 33 and the auxiliary opening 34 are closed by the shutter 35 when the electric razor is used, and the hair dust is discharged from both the openings 33 and 34. Can be prevented. If the closing start end of the shutter 35 in the closed state is brought into close contact with the stepped portion on the closed end side of the regulation stepped portion 51, there is a possibility that fouling is sandwiched between the two and solidifies. In order to prevent such clogging of fluff, a fuzzy reservoir 55 is provided by providing a bowl-shaped gap between the closing start end of the shutter 35 in the closed state and the stepped portion on the closed end side of the regulating stepped portion 51. When the outer blade holder 13 is detached from the razor head 2, the shutter 35 is held in the closed position and protrudes from the head case 12. Further, the liquid receiving opening 33 and the auxiliary opening 34 have a tapered arch shape in which the joint edge of the outer blade holder 13 with the razor head 2 is a notch start end. Therefore, when attaching the outer blade holder 13 to the razor head 2, the outer blade holder 13 can be accurately attached by inserting and attaching the liquid receiving opening 33 and the auxiliary opening 34 to each shutter 35.

  An opening protrusion (opening tool) 57 is provided on the inner surface of the head sink 22 adjacent to the nozzle 32 in order to open the shutter 35 using the mounting operation of the electric razor to the loading portion 21. When the razor head 2 is inserted into the inner surface of the hed sink 22, the passive protrusion 52 of the shutter 35 is received by the opening protrusion 57 and held in that position. As a result, in a state where the electric razor is received and supported by each receiving portion 27, the shutter 35 is operated to open against the urging force of the shutter spring 54, and the liquid receiving opening 33 and the auxiliary opening 34 can be opened. In this open state, the nozzle port 32 a of the nozzle 32 is located inside the outline of the razor head 2 in a normal state, and slightly enters the fuzz chamber R from the opening surface of the liquid receiving opening 33 ( (See FIG. 1). Further, as indicated by an imaginary line in FIG. 6, the entire tip surface of the nozzle 32 faces the region within the opening edge of the liquid receiving opening 33. As described above, when the tip of the nozzle 32 is positioned on the inner side of the outline of the razor head 2 and further facing the region within the opening edge of the liquid receiving opening 33, the cleaning liquid is surely ejected into the fuzz chamber R. Can be supplied.

  The power supply arm 18 is supported by the guide cylinder 64 of the localization post 17 so as to be slidable up and down, and is urged upward by a compression coil spring 60 disposed therebetween. As shown in FIG. 4, a socket 61 connected to the power supply plug 11 of the electric razor is provided on the lower surface of the protruding end of the power supply arm 18, and the power supply arm 18 is resisted against the biasing force of the previous spring 60. The socket 61 can be electrically connected to the plug 11 in the depressed state. In order to maintain this power supply state against the urging force of the spring 60, the power supply arm 18 is cyclically switched between a locked state and an unlocked state between the arm tube 63 of the power supply arm 18 and the guide tube 64 of the positioning post 17. An alternative lock mechanism is provided.

  As shown in FIG. 8, the lock mechanism includes a heart-shaped lock groove 65, V-shaped guide bodies 66 and 67 provided above and below the lock groove 65, and a lock spring 68 that circulates along the lock groove 65. Constitute. When the power supply arm 18 is pushed up by the spring 60 and is in the standby position, the tip of the lock spring 68 is hooked on the lower end recess 69 of the lock groove 65. When the feeding arm 18 is pushed in from this state, as the arm cylinder 63 descends, the tip of the lock spring 68 is guided by the lower guide body 67 to the groove on the right half side of the lock groove 65. As soon as it is pushed and passes through the upper end of the groove on the right half side, the lock spring 68 returns to its neutral position by its own elasticity.

  As a result, the distal end of the lock spring 68 is hooked on the upper end recess 70 of the lock groove 65 to lock and hold the power feeding arm 18 at the lower connection position. When the feeding arm 18 is pushed in again, the tip of the lock spring 68 is guided by the upper guide body 66 and pushed to the left half groove of the lock groove 65 and passes through the lower end of the left half groove. At the same time, the lock spring 68 returns to the neutral position at the center of the left and right by its own elasticity, and again latches on the lower end recess 69. Thereafter, the power supply arm 18 can be alternately held at the standby position and the lock position by repeating a series of circulation operations.

  In order to take in and out the tank 19 disposed inside the housing 16, the housing 16 can be moved up and down between a lower use position and an upper retreat position by an elevating mechanism. 9 to 11, the elevating mechanism is integrally formed with the base 15 and a pair of left and right guide frames 72 for guiding the housing base 16 </ b> B so as to be movable up and down, and a pair of left and right X-shaped elevating mechanisms. Link 73, 73, one elevating link 73, a tension coil-shaped spring 75 stretched between the bracket 74 of the housing base 16 </ b> B, and the housing base 16 </ b> B at the use position against the urging force of the spring 75. It is composed of an elevating lock mechanism that holds the lock. The rear ends of the elevating links 73 and 73 are pivotally supported on the base 15 and the housing base 16B, respectively, but the front ends of both the links 73 and 73 are free ends, and are moved back and forth along the base 15 and the housing base 16B. Can slide.

  The elevation lock mechanism includes a U-shaped lock frame 79 disposed on the upper surface of the housing base 16 </ b> B, a fixed claw 81 that engages with a lock claw 80 provided on the lock frame 79, and the lock claw 80 is engaged with the fixed claw 81. The lock frame 82 includes a lock spring 82 that moves and urges the lock frame 79 in the mating direction, a lock lever 79 that is unlocked against the urging force of the lock spring 82, and a release lever 83 that is vertically long. As shown in FIG. 9, the operation portion 85 provided at the upper end of the release lever 83 is exposed in the upper and lower middle portions of the back wall of the loading portion 21 and is released unless the electric razor is removed from the loading portion 21. The lever 83 cannot be pushed in and operated. The release lever 83 is pivotally supported in the middle by a pin 86 and can swing back and forth. The operation portion 87 at the lower end of the release lever 83 is in contact with the back surface of the lock frame 79.

  When the operation portion 85 of the release lever 83 is pushed in when the housing 16 is in the use position, the lock frame 79 is slid to the left in FIG. 9 against the lock spring 82, so that the lock claw 80 is fixed. The engaged state with the claw 81 is released. Simultaneously with the unlocking, one lifting link 73 is pulled toward the bracket 74 by the spring 75, and the sliding end of the other lifting link 73 is also slid in the same direction. Accordingly, the links 73 and 73 change from the X-shaped posture crushed up and down as shown in FIG. 9 to the X-shaped posture long as shown in FIG. 11 and push up the entire housing 16. .

  As described above, when the housing 16 is opened, the pump unit 31 and the drain pipe 43 of the head sink 22 are detached from the tank 19, so that the tank 19 can be taken in and out of the base 15. When the housing body 16A is pushed down after the tank 19 is returned to the base 15, the elevating links 73 and 73 are displaced in the direction of widening forward and backward against the spring 75, and the lock claw 80 gets over the fixed claw 81. Then, it engages with the fixing claw 81 again to hold the housing 16 in the use position. At the same time, the pump unit 31 and the drain pipe 43 are inserted into the tank 19.

  Next, the operation mode of the cleaning device and the operation in each operation mode will be described. In the cleaning device, the electric razor is loaded in a proper posture in the loading portion 21, the tank 19 is disposed at a predetermined position on the base 15, and the power feeding arm 18 is pushed down to the connection position, so that the electric razor Can be operated only in a state where each of the following conditions is satisfied, and the driving current of the motor 37 for driving the pump 36 is a certain value or more, that is, the cleaning stored in the tank 19 The condition for continuous operation is that the liquid level is above a certain level.

A detection switch 91 is provided, and a third detection switch 92 for detecting the pushed-down state of the power feeding arm 18 is provided. If the select button 23 is turned on in a state satisfying these operating conditions, the cleaning-drying mode is set. If the select button 23 is turned on twice within a predetermined time, the drying mode is set. When the select button 23 is turned on three times within the predetermined time, Reset state. When the charging button 24 is turned on, the charging mode is set. In FIG. 12, the cleaning device and the electric shaver are connected to each other via a power supply line 97 and a signal line 98, and the normally open switch 93 is turned on by a command signal from the control unit 99 on the cleaning device side. Electric current for driving the motor and charging can be supplied. The reason why the normally open switch 93 is interposed is to prevent the plug 11 and the socket 61 from being corroded. The control unit 100 on the electric razor side is composed of a CPU, a charge control IC, and the like.

  As shown in FIG. 13, in the cleaning-drying mode, after the select button 23 is turned on, the pump driving motor 37 is activated, and the cleaning liquid is supplied to the fuzz chamber to start cleaning. The At the same time, the normally open switch 93 is turned on so that the electric shaver motor 6 can be activated. In the pre-stage process in which a predetermined time has elapsed from the start of cleaning, the pump driving motor 37 is intermittently driven to alternately supply the cleaning liquid and discharge the cleaning liquid from the razor head 2. At the same time as the previous stage is completed, the previous motor 37 is continuously driven to continuously supply the cleaning liquid, and at the same time, the motor 6 that drives the inner blade 4 and the inner blade of the center blade 5 is intermittently driven to perform cleaning. Go to the next process. Starting and stopping of the motor 6 and the motor 37 during intermittent driving are controlled by a command signal from the control unit 99. When a certain time has elapsed from the start of the subsequent process, the energization of the pump driving motor 37 is stopped and the cleaning mode is terminated. When the pump driving motor 37 is intermittently driven as described above to alternately supply the cleaning liquid and discharge the cleaning liquid from the razor head 2, the hair in the pre-cleaning process. It is possible to wash away while preventing debris from scattering in the razor head 2. After roughly discharging the hair chips in the previous stage, the inner blade 4 is intermittently driven to stir the cleaning liquid, and the hair chips and sebum adhering to the inner blade 4 and its periphery can be forcibly washed away. it can.

  Simultaneously with the end of the cleaning mode, the blower fan 29 is activated to start the drying mode, and the drying air is blown toward the razor head 2. Even after shifting to the drying mode, the inner blades 4 and the inner blades of the center blade 5 are intermittently driven for a certain time, and thereafter are completely stopped. When the predetermined time has elapsed, the energization to the blower fan 29 is stopped and the drying mode is terminated. At this time, if the voltage of the secondary battery 8 inside the electric shaver is 20% or more of the voltage at the completion of charging, the cleaning-drying mode is terminated, and if the voltage is less than 20% of the voltage at the completion of charging. The mode automatically shifts to the charging mode, and the secondary battery 8 is charged.

  The drying mode includes only the drying mode in the above-described cleaning mode, and the sequential operation described above is performed in the same manner. When only charging is performed, the charging button 24 is turned on. In this case, as shown in FIG. 14, the charging button 24 is turned on, and at the same time, the charging of the secondary battery 8 is started, and is finished when the voltage reaches a predetermined value.

  The cleaning liquid sprayed into the fluff chamber R during cleaning collides with the inner blade 4, the outer blade 3, the inner wall of the outer blade holder 13, and the like, and is further stirred by the inner blade 4 that is rotationally driven. Contact with each member in the chamber R to wash away freckle and sebum. A certain amount of cleaning liquid is continuously fed to the fuzz chamber R. Therefore, the interior of the hair chamber R is always occupied by the filtered cleaning liquid, and the cleaning liquid stirred by the inner blade 4 is discharged mainly to the head sink 22 through the outer blade 3 and is drained. 43 and the reflux pipe 44 are collected in the tank 19. As described above, when the cleaning liquid in the fouling chamber R is forcibly replaced, the fouling and sebum washed off from the inner blade 4 and the outer blade 3 are removed from the razor head 2 together with the discharged cleaning liquid. As a result, a series of cleaning operations can be performed effectively in a short time.

  At the time of cleaning, at the same time as the cleaning liquid is fed by the nozzle 32, external air is attracted from the ventilation space S between the nozzle port 32 a and the liquid receiving opening 33 to the inside of the razor head 2. The attracted air is agitated together with the cleaning liquid by the inner blade 4 to promote foaming of the cleaning liquid. Therefore, the cleaning effect can be improved while maintaining the cleaning state in which the cleaning liquid and the bubbles are mixed. Furthermore, the fluff and sebum stuck to each part by the bursting impact of the foam can be peeled off and washed effectively.

  Further, when an auxiliary opening 34 is opened in the razor head 2 in addition to the liquid receiving opening 33, the interior of the razor head 2 and the external space can be communicated with each other through the auxiliary opening 34, so that the cleaning liquid in the razor head is removed from the outer blade. 3 can be expelled, and when the outer blade 3 is clogged with chips and the cleaning liquid cannot be sufficiently discharged, the cleaning liquid is discharged from the auxiliary opening 34 and cleaned in the razor head 2. The liquid can be prevented from filling up. Further, at the time of drying, dry air is introduced from the auxiliary opening 34 to promote replacement of air in the razor head 2, and the inner blade 4 and the wall surface inside the razor head can be effectively dried. As shown in FIG. 1, when the electric razor is mounted on the loading unit 21 in an inverted posture, the liquid receiving opening 33 is opened on the lower surface side of the outer blade holder 13, so that the cleaning liquid is supplied from the nozzle 32. In this state, it is expected that a part of the liquid receiving opening 33 overflows, but in this case as well, external air can be introduced from the ventilation space S into the razor head 2 to improve the cleaning effect.

  A cleaning liquid containing soap or an aqueous alcohol solution can be applied as the cleaning liquid. In this embodiment, cleaning is performed with the cleaning liquid. The present inventors prepared various cleaning liquids having different components and confirmed the cleaning effect. Furthermore, the chemical resistance with respect to the washing | cleaning liquid of each member provided in the razor head 2 was confirmed. As a result, it was confirmed that when a cleaning liquid having the following components was used as a cleaning liquid, a suitable cleaning effect was obtained and there was no problem with the corrosive action of the cleaning liquid components. The cleaning liquid is prepared by mixing water, which occupies most of the cleaning liquid, with a surfactant, an antibacterial agent (bactericidal agent), and a small amount of a fragrance and a coloring agent. Specifically, an aqueous solution containing 0.25% by weight of polyoxyethylene tridecyl ether as a surfactant, 0.10% by weight of cetylpyridinium chloride as a bactericidal agent, and a trace amount of silver ions as an antibacterial agent is cleaned. Liquid. Instead of silver ions, fine silver powder having a particle size adjusted to around several nanometers can be applied.
