[filter]
As shown in FIGS. 30 to 32, the filter 700 includes a filter frame 701 and a filter material 704 attached to the frame.
The filter frame (701) has a flat ship shape with a flat bottom and an upper opening.
The front and rear length of the filter frame (701) is a little less than a half of the tank body (601), the width is a length that fits in the back of the tank body without backlash, and the frame height is 30 times the tank body height. %. The front frame (702) of the filter frame (701) is largely inclined forward so as to form approximately 160 ° with respect to the bottom frame (703).
The bottom frame (703) and the front frame (702) are formed in a lattice shape, and a water-permeable flexible filter material (704) is placed thereon. The coarseness of the filter material (704) is 100 to 150 mesh.

The important point here is that the filter (700) is mounted at a position higher than the maximum liquid level in the set range of the liquid storage tank (600) and is not immersed in the cleaning liquid.

[Auxiliary filter]
The auxiliary filter (800) also includes a filter frame (801) and a filter material (805) attached to the frame.
The filter frame (801) also has a flat ship shape with a flat bottom and a top opening, but has a height of about twice the height of the filter frame (701) of the filter (700), and the upper end is A small amount of liquid comes out from the liquid tank (600).
The front frame (802) of the filter frame (801) is inclined forward so as to form approximately 130 ° with respect to the bottom frame (803).
The bottom frame (803), the front frame (802), and the rear frame (804) of the filter frame (801) are widely opened, and the openings are closed with the filter material (805). The filter material (805) has the same roughness as the filter material (704) of the main filter (700).

  The auxiliary filter (800) may be filtered through the main filter (700) and the cleaning solution may be secondarily filtered to improve the filtration rate. However, in the examples, since electrolytic water is used for the cleaning liquid as described below, impurities such as swarf and sebum collected in the auxiliary filter (800) immersed in the electrolytic water in the liquid storage tank (600) are electrolyzed. The auxiliary filter (800) is removed because it hinders the solution of the problems of the conventional electric razor washer, such as an increase in water concentration.

[Detection of insertion of electric razor head into cleaning device]
Using one of the two charging contacts (7) and (7) for the electric razor (8) and the dedicated contact (7a) for communication, charging the electric razor (8) into the cleaning device (100) Is detected.
When the head part (2) of the electric razor (8) is inserted downward into the enclosure frame (300), the decorative cover (6a) on the back of the electric razor (8) is attached to the contact (400) of the cleaner (100). In contact with (400) (400a), the contacts (400) (400) (400a) are sunk against the torsion spring (402).
The contacts (7), (7), (7a) of the electric shaver (8) and the enclosure frame (300) with both ends of the head part (2) contacting the receiving part (not shown) at the bottom of the enclosure frame (300) The positions of the upper contacts (400) (400) (400a) correspond to each other. The contacts (400), (400), (400a) are urged inwardly of the enclosure frame (300) by the urging force of the torsion spring (402), so that the decorative cover is applied during insertion of the head portion (2). It slides while pushing the surface of (6a) and is guided by the tapered wall surface (61b) of the holes (61) (61) (61a) exposing the contacts (7) (7) (7a) of the electric razor (8). It securely contacts the contacts (7), (7) and (7a) of the electric razor (8).

Accordingly, it is detected that the head portion (2) of the electric razor (8) has been inserted at the correct position of the enclosure frame (300). Therefore, a special detector such as a limit switch for detecting the insertion of the electric razor head portion (2) becomes unnecessary.
Even if the insertion of the electric razor (8) into the enclosure frame (300) is slightly displaced, the contact (7) (()) is caused by the guiding action of the tapered wall surface (61b) of the holes (61) (61) (61a). 7) (7a) is guided to the contacts (400), (400) and (400a), the posture of the electric razor (8) is correctly corrected, and the position of the cleaning liquid injection port (305) with respect to the head part (2) is shifted. Can also be prevented.
The contacts (400), (400) and (400a) on the cleaner (100) side are urged by the torsion spring (402) against the contacts (7), (7) and (7a) on the electric razor (8) side. Then, when cleaning the electric razor head portion (2) described later, the contacts (7), (7), (7a), (400), (400), (400a) are caused by vibration when the electric razor (8) is driven. Self-cleaning can be realized.

  As described above, on the back surface of the handle portion (1) of the electric razor (8), the tip surfaces of the three contacts (7), (7), (7a) are in the same plane, and the contacts (7), (7), (7a) Although the surface of the upper decorative cover (6a) is curved three-dimensionally so as to be familiar to the hand, the three holes (61) exposing the contacts (7) (7) (7a) are exposed. The opening edge heights of (61) and (61a) are aligned with a plane substantially parallel to the plane including the contacts (7), (7) and (7a). Therefore, the three contacts (400), (400), and (400a) on the enclosure frame (300) may have the same amount of protrusion into the enclosure frame (300). That is, the three contacts (400) (400) (400a) can have the same shape, and the contacts (400) (400) (400a) can be easily manufactured. The operation of attaching 400a) to the block (403) is also easy.

[Control of washing machine]
The following various controls are performed by a program incorporated in the control board (101) provided on the front inner surface of the outer cover (900).
In the embodiment, the control is performed under the following conditions.
I. The cleaning liquid is obtained by changing the tap water into electrolyzed water in the liquid storage tank (600).
B. The electrolyzed water is replaced with a fresh one every week (every time the seventh washing is finished once a day).

The control is explained together with the procedure for using the scrubber.
As shown in FIG. 20, the push button (901) is pushed to raise the outer cover (900) and the mounting base (202), and the storage tank (600) filled with tap water is slid to guide frame (205). Insert into.
The outer cover (900) is lowered, and the electrode plate case (500) and the pump (504) are immersed in the liquid storage tank (600). When the outer cover (900) is lowered, the lock claws (206) and (209c) are engaged and automatically locked.
Since the program is reset every time the outer cover (900) is raised, the outer cover (900) is not raised until the seventh washing of the electric razor (8) is completed.
When the seventh cleaning is completed, a replacement of the cleaning liquid in the liquid storage tank (600) is automatically urged by a buzzer, a lamp (both not shown) or the like.

As shown in FIGS. 19 and 20, the head portion (2) of the electric shaver (8) is inserted into the enclosure frame (300), and the cleaning switch button (903) on the outer cover (900) is pushed.
The program is started by pressing the cleaning switch button (903). First, it is determined whether or not the inserted electric shaver (8) corresponds to the cleaning device (100).
Next, if the electric razor (8) corresponds to the cleaning device (100), it is determined whether or not the cleaning liquid in the liquid storage tank (600) is at the set lower limit height.
When the electric razor (8) does not correspond to the cleaning device (100), or when the liquid level of the liquid storage tank (600) does not reach the set lower limit height, an alarm is issued with a buzzer, a lamp or the like.

If the liquid level of the liquid storage tank (600) is appropriate, the anode plate (501) and the cathode plate (502) are energized to change the water in the liquid storage tank (600) to electrolyzed water. The electrolysis time of the example is set to 10 minutes.
The electrolysis of water is performed at the time of the first cleaning out of the seven cleanings, and the first electrolysis time is used for the preliminary cleaning described later in the second and subsequent cleanings.

[Washing on the first day]
Cleaning is divided into preliminary cleaning and main cleaning.
In the first cleaning, the preliminary cleaning is omitted, and the main cleaning is immediately started after the electrolysis of water.
In this cleaning, the pump (504) is operated intermittently for several minutes, in the embodiment, for 6 minutes. The operation time and the downtime are halved.
The cleaning liquid enters the blade case (31) from the cleaning liquid injection port (305) from one end of the gap S between the shaving outer blade (32) and the rough shaving outer blade (33) at the time of the electric razor head (2). Is injected. The cleaning liquid flows out from the clearance S, the blade holes of the inner blades (35) and (35), the outer blades (32), (33) and (34), and from the discharge port (306) of the enclosure frame (300) to the main filter ( 700).
As described above, the cleaning liquid injection port (305) sprays the cleaning liquid into the blade body case (31) aiming at the clearance S between the outer shaving blade (32) and the roughing outer blade (33). It can be reliably guided into the blade case (31).

In addition, since the cleaning liquid is sprayed from one end side of the gap S to the blade case (31), the cleaning liquid is not obstructed by the vibrator (4) protruding to the center of the blade case (31). It can be injected into the blade case (31).
Further, by spraying the cleaning liquid directly from the one end side of the gap S onto the blade case (31), a strong flow of the cleaning liquid toward the other end side is generated, and the cleaning effect can be enhanced. This is an effect that cannot be obtained simply by immersing the head portion (2) in a container in which a cleaning liquid is stored.
During this time, the drive motor (12) of the electric razor (8) is also controlled to operate intermittently, and the inner blades (35) (35) (36) reciprocate intermittently. The inclination of the rib (35e) (35e) in the blade frame (35b) of the inner blade (35) (35) increases the stirring force against the cleaning liquid, and the inner blade (35), outer blade (32) (33) (34) ), Scraps, sebum and the like adhering to the blade case (31) can be washed away more effectively.

[Dry]
When the main cleaning is completed, the fan (309) is activated.
The air blown from the fan (309) passes through the outer blade row from the back side of the head part (2) in the enclosure frame (300) and flows to the front side of the head part (2), and part of the enclosure frame (300) It also flows out from the discharge port (306) at the bottom of the filter toward the filter (700). Thereby, the head part (2) and the filter (700) can be dried simultaneously.
In the embodiment, the operating time of the fan (309) is 2.5 hours.

[charging]
When the drying process is completed, the remaining charge of the electric razor (8) is detected, and if it is less than the set value, charging is performed. Regardless of the remaining amount of charge, it can be controlled to be charged when the operation of the fan (309) is completed, so that a full charge state can always be obtained.
The first cleaning is completed in the above process.

[Control of cleaning and drying after 2 times]
The second and subsequent cleanings are the same as in the first cleaning except that the time required for electrolysis of water in the first cleaning is used for the preliminary cleaning.
The pre-cleaning of the embodiment is intermittent spraying of the cleaning liquid from the cleaning liquid spraying port (305) as in the case of the main cleaning. Specifically, the 2-second spray 18-second stop is repeated 20 times.

[Another embodiment of the cleaner side contact]
FIG. 36a shows another embodiment of the contacts (400) (400) (400a) of the scrubber enclosure (300).
The contacts (400), (400), and (400a) are formed in a triangular pyramid shape with a sharp tip, and are urged by a spring (405) to project the sharp tip from the hole (300a) of the enclosure frame (300). ing.
Even if the cleaning liquid E adheres near the contacts (400), (400), and (400a) so as to short-circuit the contacts, by inserting the electric shaver (8), as shown in FIG. (400a) is pushed by the contacts (7), (7) and (7a) of the electric razor (8) and dents against the spring (405), so that the contacts (7), (7) and (7a) are removed from the hole edge. The short circuit between the contacts (400) (400) (400a) is eliminated.

  FIG. 37 shows a state in which the contacts (400), (400), and (400a) are arranged in a fixed state on the washer-side enclosure (300). In this case, the cleaning liquid E scattered near the contacts has a tank shape. The contacts (400), (400), and (400a) are short-circuited, or impurities in the cleaning liquid generate an electric resistance component and cause a failure. In FIG. 36, such a problem can be prevented from occurring.

[Contacts using magnets]
In FIG. 38, a magnet (70) is interposed between the contacts (7) and (7) of the electric razor (8) through a thin insulating film (not shown), and in the same manner, the washer side enclosure frame (300 ) Between the contacts (400) and (400) above, a magnet (71) is interposed via a thin insulating film (not shown) to reinforce the contact pressure between the contacts (7) and (400). Yes.
When the three contacts (7), (7), (7a), (400), (400), and (400a) are brought into contact with each other as in the embodiment, two magnets (70), (70), (71 ) (71), contact (7), magnet (70), contact (7a), magnet (70), contact (7) on the electric razor (8) side, and on the electric razor (8) side. , Contact (400), magnet (71), contact (400a), magnet (71), contact (400). As a result, the lines of magnetic force can be captured efficiently, and the contact pressure between the contacts (7) and (400) can be further enhanced by maximizing the magnetic flux density.
In addition, since the contacts (7), (7), (7a), (400), (400), and (400a) where the magnetic force is applied are brought into contact with each other, the displacement of the contacts may be caused by vibration caused by the driving of the electric razor during cleaning. , The momentary contact between the contacts can be eliminated.

  FIG. 39 shows an example of using magnets (70) and (71) in the conventional contact contact. In the main body case (15) of the electric razor (8), a magnet (70) is arranged between the contacts (7) and (7) apart from both, and the contacts ( Between (400) and (400), a magnet (71) is provided apart from both. Since the magnetic force of the magnets (70) and (71) is weakened by the square of the distance, an expensive strong magnet was required to enhance the contact pressure between the contacts (7) and (400). In addition, there is a problem that the contacts (7) and (400) are likely to be misaligned and the contacts are easily separated from each other. As described above, in the case of the embodiment of FIG. 38, this problem can be solved.

[Control of driving voltage of electric razor]
The driving voltage of the electric razor is normally controlled such that the rotational speed of the inner blade drive motor (12) (that is, the number of reciprocating operations of the inner blade (35)) is about 8000 rpm. When the electric razor head section (2) is cleaned, the motor (12) is also controlled to be driven at the motor rotational speed when it is turned on / off.
On the other hand, the inventors of the present application have found through trial and error that a frequency band in which sawdust is likely to fall out of the blade frame and a frequency band in which sebum dirt is likely to be peeled are different during cleaning of the electric razor.
For example, in order to drop the sawdust from the blade case (31), it is effective to operate the motor (12) in a lower frequency band than the reciprocating operation of the normal inner blade (35). In order to remove the sebum dirt, it is effective to operate the motor (12) in a higher frequency band than the reciprocating operation of the normal inner blade (35).

Therefore, by controlling the rotational speed of the motor (12) during washing so that the sebum dirt is easily removed and shifted to a high frequency band where the sebum dirt is easy to peel off, both the soot and sebum dirt are controlled. The cleaning effect was improved.
Specifically, as shown in FIG. 44, the duty ratio of the voltage applied to the motor (12) is changed so as to increase stepwise, and the motor (12) is changed from low rotation (4000 rpm) to high rotation (10000 rpm). Shifting up to.
Thereby, the sawdust can be effectively removed from the blade case (31) in the low rotation zone of the motor (12), and sebum dirt adhering in the high rotation zone can be effectively removed.
