Description

  The present invention relates to an electric razor cleaning device that cleans hair chips and sebum adhering to the inside of a razor head while feeding a cleaning liquid. The cleaning device includes a tank for storing the cleaning liquid and a pump for forcibly feeding the cleaning liquid in the tank to the razor head. The electric razor includes an electric razor and an electric safety razor equipped with a vibrator.

  This type of cleaning device is known from, for example, Japanese Patent Application Laid-Open No. H10-228707. In this case, the cleaning liquid in the tank is fed to the cleaning tank by a pump, and cleaning is performed with the razor head immersed in the cleaning liquid in the cleaning tank. In this way, in the cleaning device that cleans the razor head while circulating the cleaning liquid, the tank is placed on the upper surface of the base, and the chassis in which the pump and the cleaning tank are assembled can be moved up and down relative to the base. A cleaning device has been previously proposed (Patent Document 2).

  There, the chassis is composed of a chassis plate and a housing that covers the outer surface of the chassis plate, and the chassis plate is guided and supported by three guide posts erected on the base so that the chassis plate can be raised and lowered. The whole is energized upward. In order to lock and hold the entire chassis in the lower cleaning position against the urging force of the lift spring, a chassis lock structure is provided, and the lock release button is exposed on the outer surface of the housing. The pump is built into the chassis plate. When the lock release button is pushed in, the chassis lock structure is switched to the unlocked state, and the entire chassis jumps to the upper retracted position. In this state, the tank on the base can be taken out, and the tank and the filter can be cleaned, or the cleaning liquid can be replaced.

Japanese Patent Laid-Open No. 8-117016 (paragraph number 0020, FIG. 1) JP 2005-518913 A (paragraph number 0014, FIG. 2)

  In many cases, this type of cleaning apparatus can automatically operate a series of processes from washing to drying, and can be left standing from the start of washing to the end of drying. However, as described above, in a cleaning device having a chassis that can be raised and lowered, if the unlock button is provided on the outer surface of the housing, the unlock button may be unlocked due to mistakes or mischief. Yes, in such a case, an unexpected situation occurs.

  For example, if the unlock button is unlocked during the cleaning process, it becomes difficult to properly return the cleaning liquid pumped into the cleaning tank to the tank on the base side. It will be soiled by the cleaning liquid after cleaning including waste and sebum. Since the conventional cleaning device is loaded into the loading portion of the chassis in an inverted posture in which the electric razor is inclined obliquely, the left and right width of the chassis is large, and there is a disadvantage that a large space is required for installing and storing the cleaning device. There is also.

  The object of the present invention is to prevent the lifting / lowering lock structure from being unlocked when the electric razor is loaded in the cleaning device, and to ensure that the lifting / lowering lock structure malfunctions due to errors or mischief. An object of the present invention is to provide a cleaning device that can prevent the above. An object of the present invention is to provide a cleaning device that can prevent malfunction of the lift lock structure with a simpler structure, and thus can improve the reliability while avoiding the complexity of the entire structure of the cleaning device. . An object of the present invention is to make the cleaning device more compact by reducing the left-right width dimension and to reduce the space for installation and storage.

  The cleaning device of the present invention includes a base 15, a housing 16 that moves up and down relative to the base 15, and a lifting lock structure that locks and holds the housing 16 so as not to be lifted, and the housing 16 is displaced to an upper retracted position. In this state, the tank 19 provided on the base 15 can be taken in and out. The housing 16 is provided with a loading portion 21 that holds the electric razor in a cleaning posture. The lift lock structure includes a lock release unit 103 that performs a lock release operation on the structure. Thus, the unlocking operation by the unlocking unit 103 is restricted in a state where the electric razor is mounted on the loading unit 21.

  The unlocking unit 103 is disposed facing the loading unit 21, and the unlocking operation is restricted by covering the outer surface of the unlocking unit 103 with the electric shaver in a state where the electric shaver is mounted on the loading unit 21.

  The lift lock structure includes a lock release unit 103 that unlocks the lift lock structure, and a restriction body 130 that controls a lock release operation of the lock release unit 103. The restricting body 130 is provided so as to be displaceable between a restriction releasing posture in which a part thereof protrudes from the loading unit 21 and a restriction posture in which a part thereof retreats from the loading unit 21, and moves in a direction in which the restriction is released by the spring 131. Energize. Thus, in a state in which the electric razor is mounted on the loading unit 21, the regulating body 130 is switched to the regulating posture by the electric razor so that the unlocking operation by the unlocking unit 103 can be regulated.

  The housing 16 is supported by a lifting mechanism so that it can be moved up and down between a lower cleaning position and an upper retracted position, and is a lifting lock structure disposed between the base 15 and the housing 16. Lock is held. The housing 16 is guided and supported by a guide body 73 provided on the base 15 so as to be movable up and down, and is urged to move toward a retracted position by a lift spring 72 of a lifting mechanism. The elevating lock structure includes a lock engagement claw 88 provided on the base 15, a lock frame 89 that engages and disengages with the lock engagement claw 88, and an engagement bias in a direction in which the lock frame 89 is engaged with the lock engagement claw 88. And a lock release tool 91 for unlocking the lock frame 89 against the urging force of the lock spring 90. An unlocking unit 103 is provided on the unlocking tool 91.

  The elevating mechanism is disposed between a pair of left and right link pairs 70 formed of an elevating link 71 assembled in an X shape, and between the base 15 or the housing base 16B and the link pair 70, and is folded long in the front-rear direction. And a lift spring 72 for displacing the link pair 70 in the lifted state in a vertically long lift posture. Either one of the front end and the rear end of each lifting link 71 is pivotally supported by the base 15 and the housing base 16B so as to be relatively swingable. The other is guided and supported by a base 15 and a housing base 16B so as to be slidable back and forth.

  The housing 16 includes a housing base 16B and a housing body 16A that covers the outer surface of the housing base 16B. A head sink 22 for receiving the electric razor razor head 2 attached to the loading portion 21 is provided on the housing main body 16A. A pump 36 that pumps the cleaning liquid in the tank 19 to the razor head 2, a lock frame 89, a lock spring 90, and a lock release tool 91 are assembled to the housing base 16 </ b> B. Therefore, in a state where the housing base 16B is locked and held by the lock engagement claw 88 via the lock frame 89, the suction port 40 of the pump 36 is immersed in the cleaning liquid in the tank 19 and the drain pipe 43 of the head sink 22 is obtained. Can communicate with the internal space of the tank 19.

  In the present invention, the cleaning device is constituted by the base 15 into and out of the tank 19, the housing 16 that moves up and down relative to the base 15, and the up-and-down lock structure that locks the housing 16 so that the housing 16 cannot be raised. The tank 19 provided on the base 15 can be taken in and out while being displaced to the upper retreat position. In addition, when the electric razor is mounted on the loading portion 21 of the housing 16, it is possible to restrict the unlocking portion 103 of the lifting lock structure from being unlocked. It is possible to reliably prevent the housing 16 from being moved upward to the retracted position by switching from the locked state to the unlocked state due to mischief or user error. Therefore, the lower structures of the cleaning device such as the tank 18 and the base 15 can be prevented from being polluted with the cleaning liquid after cleaning including hair chips and sebum.

  According to the cleaning device that arranges the unlocking unit 103 facing the loading unit 21 and covers the outer surface of the unlocking unit 103 with the electric razor and restricts the unlocking operation in a state where the electric razor is mounted on the loading unit 21. Since the unlocking unit 103 cannot be operated unless the electric razor is removed from the loading unit 21, the lifting / lowering lock structure is reliably prevented from being unlocked during cleaning of the electric razor. It is possible to eliminate the contamination of the substructure with the cleaning liquid after cleaning including freckle and sebum. Further, since the electric shaver loaded in the loading unit 21 covers the outer surface of the unlocking unit 103 and restricts the unlocking unit 103 from being unlocked, an electric shaver that is not suitable for the cleaning device is loaded in the loading unit 21. Even in such a case, it is possible to reliably prevent the lifting lock structure from being unlocked. Furthermore, compared with a case where a dedicated means for invalidating the unlocking operation is separately provided, the lifting lock structure can be prevented from malfunctioning with a simpler structure, and thus the cleaning device is avoided while making the overall structure complicated. Can improve the reliability.

  In the lifting lock structure including the unlocking unit 103 and the regulating body 130 that regulates the unlocking operation of the unlocking unit 103, the regulating body 130 that can be displaced between the regulating release posture and the regulating posture is moved in the direction to release the regulation by the spring 131. According to the cleaning device that regulates the unlocking operation by the unlocking unit 103 when the regulating body 130 is switched to the regulating posture by the electric shaver in a state where the electric shaver is attached to the loading unit 21, As long as it is loaded in the loading unit 21, the unlocking operation of the unlocking unit 103 can be regulated by the regulating body 130 to reliably prevent the lifting lock structure from being unlocked. It is possible to eliminate the contamination of the lower structure of the apparatus with the cleaning liquid after washing including freckle and sebum. Further, since the regulating body 130 is switched to the regulating posture by the electric razor loaded in the loading unit 21 to prevent the lifting lock structure from being unlocked, the structure and functions of the lifting lock structure are not understood. Even a user can simply use an electric razor to load the loading unit 21 to reliably hold the lifting lock structure and use the cleaning device properly.

  In a cleaning device that locks and holds the housing 16 that moves up and down between a lower cleaning position and an upper retracted position with a lifting lock structure at the lower cleaning position, a lock engaging claw 88 provided on the base 15 and a lock A lock frame 89 that engages and disengages with the engagement claw 88, a lock spring 90 that engages and urges the lock frame 89 in a direction to engage the lock engagement claw 88, and a force against the urging force of the lock spring 90. According to the cleaning device that constitutes the lifting lock structure with the unlocking tool 91 etc. that performs unlocking operation and locks and holds the housing 16 at the lower cleaning position, the unlocking part 103 provided on the unlocking tool 91 is unlocked. By operating, the engagement state between the lock engaging claw 88 and the lock frame 89 is released, and the housing 16 is moved along the guide body 73 to the lock spring 9. Raised moved by the urging force of, it is possible to secure a predetermined space between the housing 16 and the base 15, it facilitates the loading and unloading of the tank 19. At this time, since the housing 16 is guided and supported by the guide body 73 provided on the base 15 so as to be movable up and down, the housing 16 can be prevented from swinging back and forth or from side to side when moving up and down between the cleaning position and the retracted position. Further, when the housing 16 is returned to the cleaning position, the lock engagement claw 88 and the lock frame 89 can be securely re-engaged and locked.

  According to an elevating mechanism (parallel link mechanism) in which a pair of left and right links 70 composed of elevating links 71 assembled in an X shape are used as elevating elements and these link pairs 70 are closed and biased by a lift spring 72, the link pair 70 is It is sufficient to secure a space in the housing 16 that can be displaced into a posture folded long in the front-rear direction and a lift posture long in the vertical direction, and the left-right width dimension of the housing 16 can be reduced as compared with the conventional cleaning device. Accordingly, the cleaning device can be made compact by an amount smaller than the width of the conventional device, and the space for installation and storage can be reduced. For example, when the rear end of each lifting link 71 is pivotally supported by the base 15 and the housing base 16B so as to be relatively swingable, and the front end is guided and supported by the base 15 and the housing base 16B so as to be reciprocally slidable, the housing 16 is cleaned Therefore, it is possible to reduce the space occupied by the cleaning device in the retracted position, thereby contributing to space saving.

  When the unlocking unit 103 of the unlocking tool 91 is pushed in with the electric razor removed from the loading unit 21, the passive frame 95 of the lock frame 89 opposes the lock spring 90 by the operation unit 132 toward FIG. 1. Since the sliding operation is performed to the left, the engagement state between the claw piece 97 and the lock engagement claw 88 is released. Simultaneously with the unlocking, the lifting link 71 of the link pair 70 is pulled toward the bracket 81 by the lift spring 72, and the slide pin 75 of the lifting link 71 guided by the base 15 is also slid in the same direction. Therefore, the link pair 70 is displaced from a state where it is folded long in the front-rear direction to a lift posture that is long in the vertical direction as shown in FIG. 9, and pushes up the entire housing 16 to the retracted position.

  As described above, when the housing 16 is opened, the pump unit 31 and the drain pipe 43 of the head sink 22 are separated 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 71 and 71 are displaced in the direction to open back and forth against the urging force of the lift spring 72, and the claw piece 97 is locked. While climbing over the claw 88, it engages with the lock engagement claw 88 again to hold the housing 16 in the cleaning 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 conditions can be satisfied, and the drive current of the motor 37 for driving the centrifugal pump 36 is greater than a certain value, that is, stored in the tank 19. The condition for continuous operation is that the level of the cleaning liquid is above a certain level.

  In order to detect whether or not each of the previous operating conditions is satisfied, a first detection switch 114 is provided on one side of the front surface of the head sink 22 as shown in FIG. A detection switch 115 is provided, and a third detection switch 116 for detecting the pressed state of the power feeding arm 18 is provided. When these operating conditions are satisfied, when the select button 23 is turned on, the cleaning-drying mode is set. When the select button 23 is turned on twice within a predetermined time, the drying mode is set, and the select button 23 is turned on three times within the predetermined time. Then, it will be in a reset state. When the charging button 24 is turned on, the charging mode is set. In FIG. 10, the cleaning device and the electric razor are connected to the power supply line 119 and the signal line 120, and the normally open switch 122 is turned on by a command signal from the control unit 121 on the cleaning device side. Thus, it is possible to supply current for driving the motor and charging. The reason why the normally open switch 122 is interposed is to prevent the plug 11 and the socket 61 from being corroded. The control unit 123 on the electric razor side is constituted by a CPU, a charge control IC, and the like.

  As shown in FIG. 11, 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 fluff 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 previous stage where 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 fuzz chamber R. Simultaneously with the end of the previous stage, 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 command signals from the control unit 121. When a predetermined 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 can be obtained. 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 when 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. 12, the charging button 24 is turned on, and at the same time, the charging of the secondary battery 8 is started, and is ended 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 and rotated by the inner blade 4 that is driven to rotate. Contacting each member in the waste chamber R, the hair waste and sebum are washed away. A certain amount of cleaning liquid is 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.

  If the auxiliary opening 34 is opened in the razor head 2 in addition to the liquid receiving opening 33, the cleaning liquid is discharged from the auxiliary opening 34 in the case where the outer blade 3 is clogged with chips and the cleaning liquid cannot be sufficiently discharged. It is possible to avoid discharging and filling the razor head 2 with the cleaning liquid. 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.

  In the above embodiment, the unlocking tool 91 is unlocked by making the unlocking unit 103 face the loading unit 21 and covering the outer surface of the unlocking unit 103 with the electric razor loaded in the loading unit 21. However, it is not necessary to prevent the lifting / lowering lock structure from being unlocked during cleaning of the electric razor while disposing the unlocking portion 103 at an arbitrary position on the peripheral surface of the housing main body 16A. be able to.

  Specifically, as shown in FIG. 13, the lock engaging claw 88, the lock frame 89, the lock spring 90, the lock release tool 91, the spring 129 for advancing and energizing the lock release tool 91, and the lock release described above. The elevating lock mechanism is configured by a regulating body 130 that regulates the unlocking operation of the portion 103 and a spring 131 that moves and urges the regulating body 130 in a direction to release the regulation. The unlocking tool 91 is made of a plastic product having a round shaft shape. The unlocking tool 91 has an unlocking portion 103 at the rear end and an operating portion 132 for moving the passive frame 95 of the lock frame 89 at the front end. The shaft portion of the unlocking tool 91 is guided and supported by a guide frame 133 provided on the housing main body 16A so as to be slidable back and forth, and the unlocking portion 103 is exposed to the outside of the housing from the operation window 108 opened on the rear surface of the housing main body 16A. It is.

  The regulating body 130 is integrally provided with a vertically long slide shaft 135 and a passive piece 136 that projects forward from the upper end of the slide shaft 135, and guides and supports the slide shaft 135 with a guide frame 137 so as to be slidable up and down. Thus, it is possible to slide up and down between the lower restriction posture and the upper restriction release posture. The spring 131 is disposed between the upper guide frame 137 and the passive piece 136 and moves and urges the entire regulation body 130 in a direction to release the regulation. The passive piece 136 in the normal state protrudes from the operation window 139 opened in the front wall of the stereo post 17 to the loading portion 21 and is held in the restriction release posture indicated by an imaginary line.

  When the electric razor is loaded into the loading portion 21, a part of the main body portion 1 comes into contact with the passive piece 136 and pushes down the regulating body 130 against the urging force of the spring 131 to switch to the regulated posture. Due to this change in posture, the lower end of the slide shaft 135 comes into contact with the front surface of the passive frame 95 and restricts the forward movement of the lock frame 89. Therefore, in a state where the electric razor is loaded in the loading unit 21, even if the unlocking unit 103 is pushed in, the lock frame 89 does not move in the unlocking direction, and the lifting lock mechanism is maintained in the locked state. Can continue. Since others are the same as the previous embodiment, the same reference numerals are assigned to the same members, and descriptions thereof are omitted.

  The feeding arm 18 in the above embodiment can be omitted. In that case, the socket 61 is disposed on the front surface side of the stereotaxic post 17, and the plug 11 that is electrically connected to the previous socket 61 is provided in the main body 1 in a state where the electric razor is loaded in the loading portion 21. The lock frame 89 and the lock release tool 91 can be formed integrally or connected together. The lock frame 89 does not have to have a frame structure, and can be formed of a rod-like structure including at least one of the front and rear slide frames 94. Further, the lock frame 89 can be configured to swing and displace with the lock engagement claw 88 in addition to sliding back and forth with respect to the lock engagement claw 88.

  In the above embodiment, cleaning is performed by injecting the cleaning liquid into the fuzz chamber R with the nozzle 32, but the present invention performs cleaning while continuously supplying the cleaning liquid to the surface of the razor head 2. The present invention can be similarly applied to an apparatus and a cleaning apparatus that performs cleaning by immersing the razor head 2 in a cleaning liquid continuously supplied to the head sink 22. In addition, the electric razor does not need to be loaded in an inverted posture with respect to the loading unit 21, for example, in a cleaning device that is loaded in a posture in which the entire electric razor is lying down with the razor head 2 slightly tilted downward. Can be applied as well. The pump unit 31 does not need to be disposed in the tank 19, and at least the suction port 40 may be disposed in the tank 19. In this case, the pump 36 and the motor 37 can be disposed, for example, on the upper surface of the housing base 16B.

  In addition to the above embodiment, the pump 36 need not be a centrifugal pump, and may be a rotary pump, a gear pump, or a reciprocating pump. The inner blade 4 need not have a rotary inner blade drive structure, and the present invention can also be applied to an electric shaver in a form in which the inner blade 4 is driven to reciprocate. The guide pair 73 does not need to be formed of a frame, and can be formed in a rod shape or a tubular shape. The lift spring 72 can be hooked between the base 15 and the elevating link 71 that moves back and forth along the base 15. The link pair 70 described in the embodiment can be arranged in the reverse direction.
