Description

Description: TECHNICAL FIELD The present invention relates to a rotary electric shaver having a mechanism for discharging whiskers accumulated in a cutting chamber.

[Conventional technology]

With the conventional beard cleaning structure, like the actual opening 59-165168, by rotating the ring that is rotatably locked to the outer peripheral part of the body, the hair collection plate provided in the cutting chamber is attached to the side wall of the body. Engage with the projection that connects the through hole that is inclined and opened,
It has a structure that moves up and down.When cleaning, the hair collecting tray is raised and the whiskers discharging fan arranged on the hair collecting tray is engaged with the inner blade support tool to discharge the whiskers by rotating the motor. Met.

[Problems to be solved by the invention]

In the above-described conventional technique, contact resistance is generated due to contact resistance between the body and the hair collection tray or the engaging portion of the inclined hole in the side wall of the body and the projection of the hair collection tray, resulting in poor operation feeling. Further, there is a problem that the structure becomes complicated. Therefore, the present invention solves such a problem, and an object of the present invention is to eliminate whiskers without a manual mechanism member such as a hair collecting tray necessary for transmitting power to a whisker discharging fan of the prior art. It is an object to provide a rotary electric shaver having a cleaning mechanism having an excellent discharging property.

[Means for Solving Problems] The rotary electric shaver of the present invention pushes up the inner blade supporting member that holds the inner blade body at the time of normal rotation of the motor, presses the inner blade against the outer blade, and at the time of reverse rotation, It is characterized in that the inner blade supporting member is moved in a direction away from the outer blade and is engaged with a beard scrap discharging fan to clean the beard scrap.

〔Example〕

The present invention will be described below based on examples. FIG. 1 is a main cross-sectional view of a rotary electric shaver according to the present invention, and FIG. 3 is an enlarged view of the vicinity of a joint between a motor and an inner blade support tool. It shows that the tool is raised, and (b) is a view in which the motor is reversing and the middle blade support tool and the shaving discharge fan are engaged. FIG. 2 is a plan view showing the vicinity of the discharge port. In each drawing, the outer blade 2 is screwed to the body 1, and the inner blade 4 engaged with the inner blade support 3 is pressed against the inner surface of the outer blade 2 and rotated by a motor 9 via a joint 6. It is arranged as possible. A whiskers discharge fan 5 is rotatably held in the cutting chamber 8 of the body 1. A discharge port 13 which is a hole for discharging whiskers is opened in the body 1 and penetrates the cutting chamber 8. 7
Is engaged with the concave portion 14 formed on the body 1 by the shutter and the convex portion 15 formed on the shutter 7, and is loosely fitted to the body 1 so as to be rotatable.

In FIG. 3 (a), the inner blade support 3 has a drive pin 10
A slide groove 16 that is inclined with respect to the motor axis direction is formed so that the can be moved, and is loosely fitted. The drive pin 10 is integrally formed with the joint 6. The inner blade support 3 has a slide groove 16 so that it can be easily attached to and detached from the joint 6.
It has a wide open end. The operation during shaving will be described. First, when the switch is turned on to the shaving side, the motor 9 rotates in the normal direction, so that the drive pin 10 rotates in the arrow direction. At this time, since the inner blade 4 and the outer blade 2 are in pressure contact with each other, a sliding resistance is generated, and the inner blade supporting member 3 acts as a reaction force against the rotation direction of the motor. Even when in place, the inner blade support 3 slips with the joint 6, the drive pin 10 moves upward according to the inclination of the slide groove 16, and when the drive pin 10 engages with the horizontal wall 17, the inner blade 4 moves. A proper pressure is obtained with respect to the outer blade 2, and when the drive pin hits the vertical wall 18, the positioning is completed and shaving is possible. Further, when the switch is turned off, the motor 9 tries to continue to rotate by inertia, but the inner blade support tool 3 acts as a reaction force, and thus the drive pin 10 and the inner blade support tool 3 are stopped with the positional relationship maintained. To try. Even when the rotation is stopped, the inner blade support 3 tries to be pushed down by the inner blade pressure, but since the horizontal wall 17 and the drive pin 10 are engaged with each other, the position is maintained as it is and the clutch claw A11 is provided during the shaving operation. The clutch claw B12 does not engage with each other and the fan 5 does not rotate.

Next, the operation for cleaning the shavings will be described with reference to FIG. 3 (b). First, the shutter 7 is rotated to open the discharge port 13, the switch is turned on to the cleaning side, and the motor 9 is reversed. The drive pin 10 rotates in the direction of the arrow, and the inner blade supporter 3 moves according to the inclination of the slide groove 16.
Moves downward and is positioned when the drive pin 10 hits the rounded wall 19 and the inner blade support 3 rotates. At this time, since the inner blade support 3 is moving downward, the contact pressure between the outer blade 2 and the inner blade 4 becomes low and the sliding resistance becomes small. Therefore, the tom cloth of the motor 9 at the time of cleaning can be reduced to be transmitted to the whiskers discharge fan 5. Further, at this time, the clutch claw A11 integrally formed with the inner blade support member 3 is
A centrifugal force is applied by the rotation of the whiskers discharge fan 5 by engaging with the clutch claw B12 formed integrally with the casing claw B12, passes through the discharge port 13 and is discharged to the outside of the body 1. As described above, the power transmission to the beard discharging fan 5 can be turned on and off only by switching the rotation direction of the motor, and the beard cleaning mechanism can be achieved without the need for a complicated mechanism as in the conventional case.

〔The invention's effect〕

As described above, according to the present invention, firstly, it is structurally simple and the number of parts can be reduced, so that the cost can be reduced. Secondly, since no parts such as a hair collecting plate interlocking with the shutter 7 in the prior art are required, extremely good operability can be obtained. Thirdly, at the time of cleaning, the inner blade 4 moves downward to separate from the outer blade 2 and the contact pressure between the inner blade 4 and the outer blade 2 is reduced, so that the load of the motor 9 is reduced and the rotation of the fan 5 is reduced. Since the number can be increased, the dischargeability of the beard scraps can be improved. As described above, the rotary electric shaver having an excellent cleaning mechanism can be provided.
