Description

  The present invention relates to a water-washing type electric shaver capable of washing and washing a razor head including an inner blade and an outer blade.

  In this type of electric razor, when cleaning, the outer blade frame is popped up with respect to the main body case to form a discharge gap that opens over the entire circumference between the outer blade frame and the upper cover body of the main body case. Patent Document 1 discloses that whiskers and cleaning water are discharged from the gaps.

  Further, in the electric razor of Patent Document 2, a cleaning water introduction port and a cleaning water discharge port are opened on the front wall and the left and right walls of the outer blade frame, and a cover that opens and closes the introduction port and the discharge port on the outer blade frame. Is provided. At the time of washing with water, the cover is opened and swung to open the previous washing water inlet and the washing water outlet, to introduce washing water from the inlet, and to remove the whiskers in the whisk pool together with the washing water. Drain from the wash water outlet.

  The present applicant has previously proposed an electric razor in which the outer blade holder is opened and swung during washing with water so that the periphery of the inner blade can be fully opened (Patent Document 3). There, by pushing the lock release button, the outer blade holder is slid upward by the biasing force of the spring, and the outer blade holder is opened and swung to the rear of the razor head to fully open the periphery of the inner blade. I can do it. The outer blade holder is slid upward by a few millimeters by the urging force of the push-up spring to bring the inner blade into close contact with the outer blade when the lock release button is pushed. Is similar to the pop-up structure of the electric razor of Patent Document 1. Thereafter, the user can fully open the periphery of the inner blade by sliding the outer blade holder upward and then swinging the razor head to the rear.

JP-A-60-174172 (page 4, lower left column, FIG. 10) JP 59-011885 (Page 2, upper left column, Fig. 3) JP 2001-54689 A (paragraph number 0036, FIG. 11)

  In the electric razor of Patent Document 1, a gap is formed between the outer blade frame and the upper lid body by popping up the outer blade frame with respect to the main body case, and the shavings and cleaning water at the time of washing with water are removed. It can be discharged from the gap. However, since the razor head is washed with water while the outer surface of the inner blade is covered with the outer blade frame, tap water, etc. can be applied to the inner blade frame, the inner surface of the outer blade, or the shavings adhering to the inner blade. Pressurized running water cannot be poured directly. Therefore, it is difficult to reliably remove whiskers and sebum adhering to the outer blade and inner blade. Further, since the outer blade frame is popped up by the biasing force of the spring, it is inevitable that the structure of the razor head is complicated by the pop-up arm, the biasing spring, and the guide structure of the pop-up arm. Furthermore, along with the use of an electric razor, sebum and whiskers may stick to the pop-up arm, the guide structure of the arm, or the biasing spring, preventing the outer blade frame from popping up. There is a problem in the reliability of operation when using it.

  Similarly, since the electric razor of Patent Document 2 remains in a state where the outer surface of the inner blade is covered with the outer blade frame at the time of washing with water, it adheres to the outer blade and the inner blade in the same manner as the electric razor of Patent Document 1. It is difficult to remove shavings and sebum. There is also a disadvantage that it takes a lot of time to dry the inner blade after cleaning. Furthermore, since it is necessary to open and close the cover grasped by the fingertip in the vicinity of the outer blade, there is a possibility that the outer blade is damaged when the cover is opened and closed.

  The electric razor of Patent Document 3 can fully open the periphery of the inner blade by opening and swinging the outer blade holder to the rear of the razor head, so that the shavings and sebum adhering to the outer blade and the inner blade can be more reliably secured. Can be washed. However, it is necessary to fully open the periphery of the inner blade by sliding the outer blade holder upward after unlocking and further swinging the entire outer blade holder backward. In addition, after cleaning, the outer blade holder must be closed and swung, and then slided downward to return to the locked state, and a series of operations for opening and closing the outer blade holder is troublesome. The user who operates the outer blade holder to open and swing backward must slide and hold the outer blade holder upward and then hold and hold the outer blade holder until the entire holder is opened and swinged backward. Since there is, there is a possibility that the dust is attached to the fingers. In a state where the entire body is opened and swung backward, when flowing water is poured on the inner surface of the outer blade holder, the outer blade holder wobbles around the shaft body, so that there is a disadvantage that the fluff cannot be washed away accurately.

An object of the present invention is to provide a water-washing type electric razor that can open and close a lid that opens and closes a cleaning opening easily with an operating body, and can reliably clean whiskers and the like attached to an inner blade or a fluff storage chamber. It is in.
The object of the present invention is to ensure that the outer blade holder also serves as a lid, and that the cleaning blade is opened largely by opening the outer blade holder so as to reliably remove whiskers attached to the inner blade and the fluff storage chamber. It is an object of the present invention to provide a water-washable electric razor that can be cleaned and can always keep the razor head in a hygienic state.

  The outer blade holder 6 also serves as a lid 69 that opens and closes the cleaning opening 68. The operating body 20 is supported by the main body case 1 so as to be slidable between a standby position where the outer blade holder 6 closes the cleaning opening 68 and an open position where the outer blade holder 6 opens the cleaning opening 68. As shown in FIG. 4, the cleaning opening 68 is opened in a circular shape along the lower opening edge of the outer blade holder 6 in a state where the operating body 20 is slid from the standby position to the open position.

  The lower opening of the outer blade holder 6 is engaged with the mounting portion 19 provided in the main body case 1, and the fouling storage chamber S is partitioned between the outer blade holder 6 and the main body case 1. In a state in which the operating body 20 is switched to the open position, the lower opening of the outer blade holder 6 is positioned above the bottom wall 27 of the fluff storage chamber S.

  The inner blade 4 includes a group of small blades 7 and an inner blade holder 8 that supports the small blades 7. The inner blade holder 8 is connected to the drive shaft 16. As shown in FIG. 4, the lower opening of the outer blade holder 6 is positioned above the inner blade holder 8 in a state where the operating body 20 is switched to the open position.

  As shown in FIG. 1, a holder lock structure is provided between the outer blade holder 6 and the main body case 1 to lock and hold the outer blade holder 6 so that it cannot be separated while the operating body 20 is in the standby position. The operation body 20 is provided with a release operation unit 58 for performing an unlock operation on the holder lock structure.

  The outer blade holder 6 is connected to the operating body 20 via a holder swing shaft 40 so as to be swingable. In a state where the operating body 20 is slid from the standby position to the open position and the outer blade holder 6 is positioned at the first open position, the outer blade holder 6 moves to the second open position around the holder swinging shaft 40. It can be swung (see FIG. 1).

  In a state where the outer blade holder 6 is slid to the first opening position by the operating body 20, the lower opening of the outer blade holder 6 is located closer to the upper end of the inner blade 4. The outer blade holder 6 in the first opening position is swung to the second opening position to open the periphery of the inner blade 4 and to expose the inner surfaces of the outer blade holder 6 and the outer blade 5.

  The virtual center axis P2 of the outer blade holder 6 in the second open position is orthogonal to the virtual center axis P1 of the main body case 1.

  A cleaning opening 68 is opened in the peripheral wall of the fluff storage chamber S facing the slide track of the operating body 20. The operation body 20 is provided with a trimmer unit 78, and the operation body 20 and the trimmer unit 78 are provided with a first lid body 69A and a second lid body 69B that open and close the cleaning opening 68, respectively. The operating body 20 has a standby position (the state shown in FIG. 8) for holding the trimmer unit 78 in the non-use posture, and an operating position for holding the trimmer unit 78 in the use posture by being pushed upward from the standby position. The state of FIG. 10) and the cleaning position (state of FIG. 11) pushed down from the standby position can be slid. In the state where the operating body 20 is switched between the standby position and the operating position, the cleaning opening 68 is closed by either the first lid body 69A or the second lid body 69B. The cleaning opening 68 can be opened in a state where the operating body 20 is switched to the cleaning position.

  A wiping body 91 that slides on the first lid body 69A and the second lid body 69B and wipes off the dust attached to the lid bodies 69A and 69B is disposed on the opening peripheral wall on the outer surface side of the cleaning opening 68. In a state in which the operating body 20 is slid between the standby position, the operating position, and the cleaning position, the dust attached to the first lid body 69A and the second lid body 69B can be wiped off by the wiping body 91.

  As shown in FIG. 10, the virtual center axis P <b> 3 of the outer blade holder 6 attached to the main body case 1 is tilted forward by an angle θ <b> 1 with respect to the virtual center axis P <b> 1 of the main body case 1. The trimmer unit 78 is connected to the operating body 20 via a connecting shaft 94 so as to be tiltable back and forth. In a state where the operating body 20 is slid from the standby position to the operating position, the trimmer unit 78 is refracted forward and switched to the use posture. The virtual center axis P4 of the trimmer unit 78 that is switched to the use posture and refracted forward is tilted forward by an angle θ2 with respect to the virtual center axis P1 of the main body case. The forward tilt angle θ1 of the virtual center axis P1 of the outer blade holder 6 and the forward tilt angle θ2 of the virtual center axis P4 of the trimmer unit 78 are set so as to satisfy the inequality (θ1 <θ2).

  The trimmer unit 78 disposed on the upper part of the operating body 20 is connected to the operating body 20 via a connecting shaft 94, and the sliding position (state of FIG. 12) standing on the extension of the operating body 20 is set. It is supported by the operating body 20 so that it can be refracted to a combined shaving position (state of FIG. 13) that is inclined forward with respect to 20 and adjacent to the outer blade holder 6. In the combination shaving position, the regulating body 112 provided on the trimmer unit 78 is engaged with the engaging portion 113 provided on the outer blade holder 6 to regulate the movement of the trimmer unit 78.

  On both the left and right sides of the trimmer unit 78, the restricting body 112 is projected toward the outer blade holder 6. Engagement walls 113 for engaging and holding the opposing surfaces of the pair of restrictors 112 are provided on both the left and right sides of the outer blade holder 6. As shown in FIG. 13, in a state where the trimmer unit 78 is refracted to the combination shaving position, the pair of regulating bodies 112 are engaged with the engaging wall 113 while holding the wall 113 to the left and right, The left-right movement of the trimmer unit 78 is restricted.

  A trimmer holder 101 is coupled to the upper portion of the operation body 20 via a coupling shaft 94 so as to be able to be bent forward. The trimmer unit 78 is a trimmer holder 101 and supports the trimmer unit 78 so as to be slidable back and forth along the virtual center axis P4 of the trimmer unit 78. Further, the trimmer unit 78 is floatingly supported by a float spring 104 disposed between the trimmer holder 101 and the trimmer unit 78.

  A float lock structure is provided between the trimmer unit 78 and the operating body 20 so as to restrict the float operation of the trimmer unit 78 at the sliding position. As shown in FIG. 12, the float lock structure includes a contact portion 117 provided on the trimmer base 79 of the trimmer unit 78 and a lock portion 118 provided on the operation body 20. The preceding contact portion 117 is received by the lock portion 118 at the wrinkle position, and the sinking of the trimmer unit 78 is restricted.

  A standing lock structure is provided between the operating body 20 and the trimmer holder 101 to restrict the forward tilting of the trimmer unit 78 at the sliding position. As shown in FIG. 12, the standing lock structure includes a lock body 120 supported by the operating body 20 so as to be slidable up and down, a lock spring 121 for urging the lock body 120, and a trimmer holder 101. The engagement part 122 engages / disengages with 120, and the release body 123 is configured to unlock the lock body 120 against the urging force of the lock spring 121.

  In the electric razor according to the present invention, the main body case 1 is provided with the operating body 20 that can be slid back and forth, and the lid body 69 that opens and closes the cleaning opening 68. The operating body 20 slides the lid body 69 to open the cleaning opening 68. I was able to open it. In addition, washing water is introduced into the inside of the fluff storage chamber S from the opened washing opening 68 so that the fluff and sebum adhering to the inner blade 4, the outer blade 5, the outer blade holder 6 and the like can be washed with water. did.

  As described above, in the electric shaver according to the present invention, the lid 69 is operated by the operating body 20 that reciprocally slides to open and close the cleaning opening 68, so that the cleaning opening when the inside of the fouling storage chamber S is washed with water is washed. 68 can be easily opened and closed by a simpler operation. Further, since the cleaning opening 68 is opened and closed by moving the lid 69 along with the operating body 20 reciprocatingly sliding, the cleaning opening 68 is compared with the conventional structure in which the outer blade frame is popped up by the biasing force of the spring to open the gap. Therefore, the opening / closing operation of the lid 69 can always be performed reliably.

  According to the electric razor in which the outer blade holder 6 also serves as the lid 69, the outer blade holder 6 is slid to the open position by the operating body 20, thereby cleaning the opening along the lower opening edge of the outer blade holder 6. 68 can be greatly opened in a circular shape. Therefore, unlike electric razors such as Patent Documents 1 and 2, the running water such as tap water is introduced from the arbitrary opening position into the fouling storage chamber S to wash the fuzz and sebum with water, and other than the flowing water introduction part. Hair dust and washing water can be discharged from the opening. In addition, since the cleaning opening 68 can be largely opened in a circular shape, water droplets adhering to the inner blade 4, the outer blade 5, the outer blade holder 6 and the like are dried in a shorter time, and the razor head 2 is always sanitized. Can be maintained in a typical state.

  According to the electric razor in which the lower opening of the outer blade holder 6 is positioned above the bottom wall 27 of the fluff storage chamber S in the state where the operating body 20 is switched to the open position, the cleaning opening 68 has a circular shape. Simultaneously with the opening, the opening height in the vertical direction of the cleaning opening 68 can be increased. Accordingly, the washing water for the razor head 2 is promoted by promoting the introduction of the washing water at the time of washing with water, the discharge of the washing water after the washing including the hair chips, or the replacement of the new washing water in the hair holding chamber S. Cleaning and drying can be performed more effectively in a shorter time.

  According to the electric razor in which the lower opening of the outer blade holder 6 is positioned above the inner blade holder 8, most of the inner blade 4, the drive shaft 16, the bottom wall 27 of the dust storage chamber S, and the like are cleaned with the opening 68. Can be exposed to the opening space. Accordingly, the running water can be directly flowed to the outer surface of the inner blade 4, the drive shaft 16 and the like, and the waste water and the like can be reliably washed and washed using the water pressure and momentum of the running water. Further, by flowing flowing water directly into the outer blade holder 6, it is possible to wash and wash the hair adhering to the outer blade 5 and the inner surface of the outer blade holder 6 with water.

  If a holder lock structure is provided between the outer blade holder 6 and the main body case 1 to lock the outer blade holder 6 so that it cannot be separated, the outer blade holder 6 must be operated after the structure is unlocked. The slide opening operation cannot be performed with the operating body 20. That is, after the holder lock structure is unlocked with one hand, it is necessary to slide the operating body 20 with the other hand. However, if the operation body 20 is provided with the release operation portion 58 for the holder lock structure, the operation body 20 is pushed up in that state after the holder operation of the holder lock structure is unlocked by the release operation portion 58. Thus, the outer blade holder 6 can be slid open. Therefore, even if the electric razor has a structure in which the outer blade holder 6 is locked and fixed by the holder lock structure, the main body case 1 is grasped with one hand, the unlocking operation portion 58 is unlocked with the thumb, and the operating body 20 is pushed up. By performing the sliding operation, the outer blade holder 6 can be easily slid open.

  When the outer blade holder 6 is connected to the operating body 20 through the holder swing shaft 40 so as to be swingable, the outer blade holder 6 in a state of being positioned at the first open position is centered on the holder swing shaft 40. Thus, it can be swung to the second opening position. As described above, when the outer blade holder 6 is swung to the second opening position, the periphery of the inner blade 4 can be opened to the space above it. Furthermore, the outer blade holder 6 can be opened at a position sufficiently away from the upper portion of the inner blade 4 to expose the inner surface of the outer blade holder 6 and the inner surface of the outer blade 5 toward the open space. Accordingly, it is possible to wash away the fluff by directly applying the flowing water to the periphery and the inner surface of the inner blade 4 where the entire circumference is exposed, and to the inner surfaces of the outer blade holder 6 and the outer blade 5 exposed to the open space. The hair can be washed away to every corner by direct action.

  When the lower opening of the outer blade holder 6 that is slid to the first opening position is positioned closer to the upper end of the inner blade 4, the opening height of the cleaning opening at the first opening position can be sufficiently increased. In addition, the opening area of the circular opening formed between the lower opening of the outer blade holder 6 and the peripheral surface of the inner blade 4 can be increased. Therefore, even with the outer blade holder 6 opened to the first opening position, the inner blade 4, the outer blade 5, the outer blade holder 6 and the like can be easily washed with water. Furthermore, since the outer blade holder 6 can be swung to the second open position with the lower opening of the outer blade holder 6 positioned near the upper end of the inner blade 4, the fingertip holding the outer blade holder 6 can be The outer blade holder 6 can be safely rocked and opened while avoiding contact with the blade 4.

  According to the electric razor in which the virtual center axis P2 of the outer blade holder 6 in the second open position and the virtual center axis P1 of the main body case 1 are orthogonal to each other, each of the outer blade holder 6 and the inner blade 4 in the second open position. Can be placed adjacent to each other in a washable open position. Therefore, when pouring running water with the entire electric razor in a recumbent posture, the inner blade 4 can be cleaned or the outer blade holder 6 can be cleaned simply by moving the electric razor back and forth in the recumbent posture. Further, the washing with water can be easily performed as much as it is not necessary to change the posture for washing the inner blade 4 and the posture for washing the outer blade holder 6. In addition, the outer blade holder 6 and the inner blade 4 in the second open position are in a positional relationship that is largely separated from the front and rear in a state where the electric razor is in the lying position, so that when washing with water, the outer blade 5 and the outer blade holder While avoiding the 6 and the inner blade 4 from interfering with each other, the inner blade 4 and the surrounding structure, the outer blade 5 and the outer blade holder 6 can be cleaned individually and thoroughly.

  In the electric razor provided with the trimmer unit 78 and the operation body 20 for switching the posture of the unit 78, the trimmer unit 78 and the operation body 20 can be used to open and close the cleaning opening 68 provided in the freight storage chamber S. The switching of the posture 78 and the opening and closing of the cleaning opening 68 can be performed by only one operating body 20. Therefore, it is possible to avoid an increase in the overall cost by avoiding unnecessarily complicated construction of the electric razor. Further, the outer space of the cleaning opening 68 can be opened at the time of washing with water, and the running water or the cleaning water stored in the container can be reliably introduced from the cleaning opening 68 into the fouling storage chamber S. The first lid 69A and the second lid 69B that open and close the cleaning opening 68 are provided in the operating body 20 and the trimmer unit 78, respectively, when the operating body 20 is in the standby position. This is because the cleaning opening 68 is closed by the first lid 69A. In addition, when the operating body 20 is in the operating position, the cleaning opening 68 is closed by the second lid 69B provided on the operating body 20 to prevent the cut hair from being discharged from the cleaning opening 68. is there.

  When the wiping body 91 is disposed on the opening peripheral wall on the outer surface side of the cleaning opening 68, when the operating body 20 is slid between the standby position, the operating position, and the cleaning position, the first lid body 69A and the second lid body. The swarf adhering to 69B can be forcibly removed by the wiping body 91. Therefore, when the operation body 20 is slid up and down, the hair dust is prevented from moving along with the first lid body 69A or the second lid body 69B attached, and the hair dust is prevented from moving along the main body case of the operation body 20. 1 can be prevented from clogging around the electric razor when clogging the sliding surface with 1 or when the posture of the trimmer unit 78 is switched.

  In the electric razor for tilting the trimmer unit 78 forward toward the outer blade holder 6 side, the forward tilt angle θ1 of the virtual center axis P3 of the outer blade holder 6 and the forward tilt angle θ2 of the virtual center axis P4 of the trimmer unit 78 are Is set to (θ1 <θ2), the trimmer unit 78 in the operating position is positioned in the vicinity of the outer blade 5, and the two can be combined. At the time of combi shaving, the beard that has fallen on the skin surface is brushed with the trimmer unit 78 while being shaved, and the raised beard can be immediately cut with the inner blade 4 and the outer blade 5, so that the combi shaving is effective. It can be carried out. Further, since the virtual center axis P3 of the outer blade holder 6 is tilted forward, the inner blade is compared with the electric shaver in which the virtual center axis P3 of the outer blade holder 6 is aligned with the virtual center axis P1 of the main body case 1. The whisker cutting by the 4 and the outer blade 5 can be performed appropriately and easily.

  When the trimmer unit 78 is provided with a regulating body 112 and the previous regulating body 112 is engaged with the engaging portion 113 of the outer blade holder 6 at the combination shaving position, the trimmer unit 78 is restricted from moving left and right or forward. The unit 78 can be fixedly held in the combined shaving position. Therefore, the raising action by the trimmer unit 78 and the whisker cutting action by the inner blade 4 and the outer blade 5 can be accurately performed.

  When the regulation bodies 112 are provided on both the left and right sides of the trimmer unit 78 and the pair of regulation bodies 112 are engaged with the engagement wall 113 in the left and right direction at the combi-shaving position, the trimmer unit 78 is regulated in a state where the lateral movement is restricted. Can be firmly fixed and held in the combination shaving position. Therefore, the combination shaving performed in cooperation with the inner blade 4 and the outer blade 5 is performed more accurately by restricting the trimmer unit 78 from being dragged to the skin surface and tilting obliquely or meandering left and right at the time of combing. be able to.

  When the trimmer unit 78 is guided and supported so as to be reciprocally slidable by the trimmer holder 101 connected to the operation body 20, and the trimmer unit 78 is floated and supported by the float spring 104, the trimmer unit 78 follows the change in the condition of the skin surface. You can advance or sink. Therefore, at the time of combi shaving, the cutting blade portion of the trimmer unit 78 can be moved in close contact with the unevenness of the skin surface, and comb comb shaving can be performed more lightly. Furthermore, it is possible to eliminate the roughening of the skin surface due to excessive pressing of the cutting edge portion on the skin surface during combi shaving.

  When a float lock structure is provided between the trimmer unit 78 and the operation body 20, the trimmer unit 78 is regulated at the squeezing position so that the trimming, mustache, and mustache can be accurately shaped by the trimmer unit 78. It can be carried out. Further, since the contact portion 117 provided on the trimmer base 79 is received by the lock portion 118 provided on the operation body 20 in the wrinkle position to prevent the trimmer unit 78 from sinking, the float lock structure is simplified. In addition, the sinking operation of the trimmer unit 78 can be reliably regulated.

  If an upright lock structure is provided between the operating body 20 and the trimmer holder 101 to restrict the forward tilt of the trimmer unit 78 in the squeezing position, the trimmer unit 78 can be operated even when a forward external force acts on the trimmer unit 78. It is possible to keep the standing posture by restricting the forward tilting by the standing lock structure. Therefore, the trimming unit 78 can accurately shape the sideburns, mustaches, and mustaches. In addition, since the lock body 120, the lock spring 121, the engaging portion 122 that engages and disengages with the lock body 120, the release body 123, and the like constitute the standing lock structure, the release body 123 can be simply pushed down. The trimmer unit 78 can be tilted forward by simply releasing the engagement state between the lock body 120 and the engagement portion 122.

By pushing the release knob 58 in this state forward, the relay body 59 is moved forward to tilt the passive arm 60. Thus, the lock arm 48 can be unlocked against the urging force of the arm lock spring 49.

  At the time of washing with water, first, the release knob 58 is pushed in to unlock the holder lock structure, and in this state, the slide knob 20 is slid from the standby position to the open position, and the outer blade holder 6 is moved to FIG. The first open position shown in FIG. In a state where the slide knob 20 is switched to the open position, the engagement arm 25 falls into the upper arm recess 26 and engages, so that the slide knob 20 can be held in the open position.

  As described above, by sliding the slide knob 20 upward with the release knob 58 pushed in, the outer blade holder 6 is moved to the first opening position, and the lower opening end and the base of the mounting portion 19 are moved. A cleaning opening 68 for introducing cleaning water or discharging the cleaning water together with the hairs can be opened between the end step portion 67. The cleaning opening 68 in this state is opened in a circular shape along the lower opening edge of the outer blade holder 6, and the outer blade holder 6 functions as a lid 69 for opening and closing the cleaning opening 68.

The hair chips and sebum adhering to 16 can be washed away. If washing with water is performed while the inner blade 4 is driven to reciprocate, the chance of collision between the washing water and the small blade 7 can be increased, and washing with water can be performed more effectively. In addition, by flushing the cleaning water directly onto the inner surfaces of the outer blade holder 6 and the outer blade 5, it is possible to wash away all the fluff and sebum adhering to the inner surfaces of the outer blade holder 6 and the outer blade 5. . In addition, even if the virtual center axis P2 of the outer blade holder 6 and the virtual center axis P1 of the main body case 1 are not perpendicular to each other at an angle of 90 degrees, the same water washing effect as described above can be exhibited. Therefore, in this embodiment, the intersection angle when the virtual center axis P2 of the outer blade holder 6 and the virtual center axis P1 of the main body case 1 are perpendicular to each other includes an angle in the range of 80 degrees to 100 degrees. To do.

  When the amount of fluff in the fluff storage chamber S is large, the washing water is allowed to flow from the washing opening 68 to the inner blade 4 and the bottom wall 27 while the outer blade holder 6 is opened to the first open position. Then, the fluff and sebum adhering to the inner blade 4 and the bottom wall 27 or the outer blade holder 6 and the outer blade 5 are washed away to perform pre-stage cleaning, and then the outer blade holder 6 is opened to the second open position. The cleaning can be performed again. As described above, if the chips and sebum adhering to the outer blade holder 6 and the outer blade 5 are washed away by the pre-cleaning, the chips are peeled off when the outer blade holder 6 is opened to the second open position. It is hygienic because it can eliminate adhesion.
