SUMMARY OF THE INVENTION An object of the present invention is to provide a flush electric shaver in which a cleaning opening can be opened or closed simply by reciprocating the opening/closing member.

As shown in FIG. 1, the water-washing electric shaver according to the present invention includes a razor head 2 provided with a movable blade 6 and a fixed blade 7, and a fixed blade 7 and a fixed blade holder 8 for supporting the fixed blade 7. A hair waste receiving portion 17 for receiving hair waste is provided on the bottom surface of the hair waste chamber 16 surrounded by . A cleaning opening 20 communicating with the hair waste chamber 16 and an opening/closing body 26 for opening and closing the same opening 20 are provided in the case wall facing the hair waste chamber 16 . The opening/closing body 26 is supported by a horizontal rotating shaft 23 provided in the middle in the vertical direction so that it can be opened and closed by swinging, and can be displaced between a closed posture for closing the cleaning opening 20 and an open posture for opening the cleaning opening 20. characterized by being

The opening/closing body 26 is supported by a horizontal rotating shaft 23 provided on the lower half side of the opening/closing body 26 so as to be capable of being opened and closed by swinging. can be displaced to

A finger receiving portion 27 for opening the opening/closing body 26 is formed on the upper half of the outer surface of the opening/closing body 26 .

The finger receiving portion 27 is formed of a plurality of vertical ribs 27a elongated in the vertical direction.

A detent structure is provided between the peripheral wall of the washing opening 20 and the opening/closing body 26 to engage with each other and hold the opening/closing body 26 in the closed posture and the open posture.

A detent structure is formed between a partially arc detent arm 24 provided at the lower inner surface of the opening/closing body 26 and the peripheral wall of the cleaning opening 20 facing the rocking trajectory of the detent arm 24, and engaged with each other in an uneven manner. It is formed by the detent bodies 28 and 29 and the fixed detent body 30 .

The opening/closing body 26 is provided with a closing stopper 32 that prevents the opening/closing body 26 from swinging beyond the closed position, and an opening stopper 31 that prevents the opening/closing body 26 from swinging beyond the open position. there is

An opening stopper 31 is provided at the tip of the detent arm 24 , and a lower contact portion 33 for receiving the opening stopper 31 is formed in the lower part of the peripheral wall of the washing opening 29 .

A closing stopper 32 is provided on the upper portion of the opening/closing body 26 , and an upper contact portion 34 for receiving the closing stopper 32 is formed on the upper portion of the peripheral wall of the cleaning opening 20 .

In the present invention, the opening/closing member 26 is supported by the horizontal rotary shaft 23 so as to be swingably opened and closed so that it can be swingably displaced between the open position and the closed position. According to such an electric shaver, the cleaning opening 20 can be opened or closed simply by reciprocating the opening/closing body 26 .

The opening/closing body 26 is supported by a horizontal rotating shaft 23 provided in the middle in the vertical direction so that it can be opened and closed by swinging. and the portion below the rotary shaft 23 are opened, and tap water is supplied into the hair waste chamber 16 from the upper and lower openings of the cleaning opening 20 to wash the hair waste in the hair waste chamber 16. Can be done extensively. For example, while tap water is caused to flow down into the hair waste chamber 16 from the portion above the rotation shaft 23, the tap water flowing through the portion below the rotation shaft 23 is used to remove the hair waste accumulated in the lower receiving portion 17b. can be washed off. Further, the opening/closing body 26 whose midway portion in the vertical direction is supported by the rotating shaft 23 so as to be able to swing open and close can be operated by pushing the portion above the rotating shaft 23 and the portion below the rotating shaft 23 . Since the opening/closing member 26 can be switched between the open posture and the closed posture, there is an advantage that a spring for moving and urging the opening/closing member 26 to the open posture and the closed posture can be omitted.

If the rotating shaft 23 is provided on the lower half side of the opening/closing body 26, the moment arm of the portion above the rotating shaft 23 when the opening/closing body 26 swings and opens/closes is more than the moment arm of the lower portion. We can make it big. Therefore, by operating the upper half side to open the opening/closing body 26, the opening/closing body 26 can be opened more lightly. In addition, since the vertical length of the portion of the opening/closing body 26 below the rotating shaft 23 is small, the projection dimension of the opening/closing body 26 exposed to the outside of the cleaning opening 20 when the opening/closing body 26 is opened can be reduced. Tap water can be accurately supplied in a state in which the water discharge part of the faucet is brought closer to the washing opening 20 by the same amount.

An opening/closing body 26 is supported by a rotating shaft 23 provided on the lower half thereof so as to be openable and closable, and a finger receiving portion 27 for opening the opening/closing body 26 is bulgingly formed on the upper half of the outer surface of the opening/closing body 26 . When the finger receiving portion 27 is pushed in, the opening operation of the opening/closing body 26 can be easily performed. For example, when the upper half of the opening/closing body 26 is pushed in directly, since the rotating shaft 23 is provided on the lower half side of the opening/closing body 26, the upper part of the opening/closing body 26 when the opening operation is performed is It goes over the cleaning opening 20 and enters into the inside of the hair waste chamber 16 greatly. However, since the finger receiving portion 27 bulged on the outer surface of the opening/closing body 26 is located outside the upper portion of the opening/closing body 26, the finger does not enter into the hair dust chamber 16 when the opening/closing body 26 is opened. , the opening and closing operation of the opening and closing body 26 can be facilitated.

When the finger receiving portion 27 is formed of a plurality of vertical ribs 27a elongated in the vertical direction, tap water that collides with the opening/closing member 26 can be divided and guided in an orderly manner by the group of vertical ribs 27a. Therefore, the tap water colliding with the opening/closing member 26 is diffused to prevent the tap water from colliding with each other.

If a click structure is provided between the peripheral wall of the cleaning opening 20 and the opening/closing body 26, the opening/closing body 26 can be reliably held in the closed position or the open position. Therefore, it is possible to reliably prevent the opening/closing body 26 from being erroneously opened during shaving, or from inadvertently moving to close due to the water flow during hair washing.

A detent structure with movable detent bodies 28 and 29 and a fixed detent body 30 provided between the partially arc-shaped detent arm 24 provided on the opening/closing body 26 and the peripheral wall of the cleaning opening 20 facing the swing locus of the detent arm 24. configure. According to this, since the detent structure is provided between the detent arm 24 and the facing surface of the peripheral wall of the cleaning opening 20, the structure is efficient, and the movable detent bodies 28 and 29 and the fixed detent body 30 are engaged with each other in an uneven manner. Therefore, the position of the opening/closing body 26 can be reliably held in the closed posture and the opened posture.

A closing stopper 32 and an opening stopper 31 are provided on the opening/closing body 26. - 特許庁According to such an opening/closing body 26, the closing stopper 32 prevents the opening/closing body 26 from being erroneously swung beyond the closed position in the closing direction, and the opening/closing body 26 is erroneously moved to the open position. The opening stopper 31 can prevent the rocking operation in the opening direction. Incidentally, when the opening/closing body 26 is held in the closed posture and the open posture only by the detent structure, the opening/closing body 26 may be forced to swing beyond the closed position by misunderstanding or mischief, or the opening/closing body 26 may be disengaged. There is a risk that the swing operation will be forced beyond the open position. However, if the closing stopper 32 and the opening stopper 31 are provided on the opening/closing member 26, it is possible to reliably prevent erroneous operation due to misunderstanding or mischief as described above.

An opening stopper 31 is provided at the tip of the moderation arm 24, and a lower contact portion 33 for receiving the opening stopper 31 is provided at the lower part of the peripheral wall of the cleaning opening 20. - 特許庁According to this stopper structure, the opening stopper 31 can be provided using the detent arm 24 that constitutes the detent structure, and the lower contact portion 33 can be formed using the peripheral wall of the cleaning opening 20. As a result, there is no waste in the structure, and the simplification of the stopper structure contributes to cost reduction.

A closing stopper 32 is integrally provided on the upper part of the opening/closing body 26, and an upper contact portion 34 for receiving the closing stopper 32 is provided on the peripheral wall of the cleaning opening 20. - 特許庁According to such a stopper structure, the closing stopper 32 can be integrally formed using the opening/closing body 26, and the upper contact portion 34 can be formed using the peripheral wall of the cleaning opening 20, so that the structure as a whole is efficient and The simplification of the stopper structure contributes to cost reduction.

The fixed blade holder 8 is detachably attached to the head case 13 . Rotational power of the motor 3 is transmitted to the inner blade shaft 9 by a gear train 15 arranged along the inner blade support frame 14 . The hair chips cut by the movable blade 6 and the fixed blade 7 fall into the hair dust chamber 16 inside the razor head 2 and are received by the hair dust receiver 17 on the bottom surface of the hair dust chamber 16 . The hair dust chamber 16 is a space surrounded by the fixed blade 7 , the fixed blade holder 8 , and the head case 13 , and the top wall of the head case 13 serves as a hair dust receiver 17 . The hair dust receiving portion 17 includes an upper receiving portion 17a facing the lower peripheral surface of the movable blade 6, and a lower receiving portion 17b provided in a stepped manner with respect to the upper receiving portion 17a.

A cleaning opening communicating with the hair dust chamber 16 is provided in the front wall of the fixed blade holder 8 facing the hair dust receiving portion 17 (the case wall facing the hair dust chamber 16) in order to wash away the hair dust accumulated in the hair dust receiving portion 17. 20 is provided, and the tap water flowing down to the washing opening 20 can be flow-guided toward the hair dust receiving portion 17 by a guide body 21 provided in the same opening 20. - 特許庁As shown in FIG. 3, the cleaning opening 20 is a rectangular opening elongated in the left-right direction. The guide body 21 includes a main wall 22 having the same rectangular shape as the cleaning opening 20, horizontal rotating shafts 23 protruding from both side surfaces of the main wall 22, and detent arms extending from both sides of the lower inner surface of the main wall 22. It consists of a plastic molded product integrally provided with 24 . The detent arm 24 is a partially arcuate arm, and its center position coincides with the center position of the rotating shaft 23 .

By supporting the rotating shaft 23 with a bearing hole 25 formed in the inner surface of the cleaning opening 20 , the guide body 21 functions as an opening/closing body 26 for opening and closing the cleaning opening 20 . That is, the guide body 21 also serves as the opening/closing body 26 . The opening/closing member 26 reciprocates about the rotary shaft 23, and is positioned between a closed position for closing the cleaning opening 20 as shown in FIG. 1 and an open position for opening the cleaning opening 20 as shown in FIG. can be displaced between When the opening/closing body 26 is in the closed posture, the guide body 21 is in the standby posture, and when the opening/closing body 26 is in the open posture, the guide body 21 is in the guiding posture and flows down to the cleaning opening 20. It is possible to flow and guide the filtered tap water toward the hair dust receiving portion 17 .

In order to make it easier to push the opening/closing member 26 into the hair dust chamber 16, a finger receiving portion 27 is formed on the upper half of the outer surface of the main wall 22, and the center of the rotation shaft 23 is formed. is positioned on the lower half side of the opening/closing body 26 . The finger receiving portion 27 is formed of a group of vertical ribs 27a elongated in the vertical direction, and the side surface thereof is formed in an unequal trapezoidal shape. A click structure is provided between the click arm 24 and the left and right opposing peripheral surfaces of the cleaning opening 20 to hold the opening/closing body 26 in the closed position and the open position.

As shown in FIG. 5, the detent structure is formed by two movable detent bodies 28 and 29 formed on the detent arm 24 side and a peripheral wall (fixed wall) of the cleaning opening 20 facing the rocking locus of the detent arm 24. It is composed of a fixed detent body 30. The movable detent bodies 28 and 29 consist of circular grooves recessed at the proximal end and near the end of the detent arm 24, and the fixed detent body 30 is a partially spherical projection formed on the left and right opposing circumferential surfaces of the cleaning opening 20. consists of A movable detent body 28 provided at the base end of the detent arm 24 engages with the fixed detent body 30 when the opening/closing body 26 is in the closed position, and a movable detent body 29 provided near the end of the detent arm 24 When the opening/closing body 26 is in the open position, it engages with the fixed detent body 30 . The fixed detent body 30 need not be formed on the peripheral wall of the cleaning opening 20, and may be formed on a fixed wall such as the head case 13 or the body case 1 depending on the shape and swing locus of the detent arm 24. good.

An opening stopper 31 and a closing stopper 32 are provided on the opening/closing body 26 in order to prevent the opening/closing body 26 from swinging beyond the closed position and further prevent the opening/closing body 26 from swinging beyond the open position. is provided. The opening stopper 31 is formed of a round shaft-shaped projection that protrudes in the left-right direction (horizontal direction) from the side surface of the tip end of the detent arm 24 , and is received by a lower abutment portion 33 provided on the inner peripheral edge of the cleaning opening 20 . When the opening/closing body 26 swings from the closed position to the open position, the opening stopper 31 is received by the lower contact portion 33 as shown in FIG. 4(b), and the opening/closing body 26 swings beyond the closed position. to prevent The closing stopper 32 is formed of a rearwardly rising inclined wall that continues to the upper portion of the opening/closing body 26 and is received by an upper abutting portion 34 provided on the upper portion of the peripheral wall of the cleaning opening 20 . The upper abutting portion 34 is formed of a rearward rising inclined surface having the same angle as that of the opening/closing body 26 . When the opening/closing body 26 swings from the open position to the closed position, the closing stopper 32 is received by the upper contact portion 34 as shown in FIG. do. In this state, the closing stopper 32 and the upper contact portion 34 are in close contact with each other, and the lower surface of the opening/closing member 26 is in contact with the lower peripheral surface of the cleaning opening 20, so that hair waste leaks out of the hair waste chamber 16. can be reliably prevented.

When the opening/closing body 26 is switched to the open position, the inner surface of the opening/closing body 26 is designed to allow the tap water flowing along the inner surface of the main wall 22 to flow toward the upper receiving portion 17a of the hair dust receiving portion 17. A water flow guide portion 35 is formed in the upper portion. In this embodiment, the inclined lower surface of the closing stopper 32 functions as a water flow guide portion 35 by utilizing the fact that the closing stopper 32 is formed of a rear rising inclined wall. As shown in FIG. 5, when the opening/closing member 26 is switched to the open position, the tap water flowing along the inner surface of the main wall 22 is directed to the upper receiving portion 17a of the hair dust receiving portion 17 by the water flow guide portion 35. It is possible to directly wash away the hair waste accumulated in the upper receiving portion 17a by the flow action of the tap water.

As described above, it is preferable that the opening/closing body 26 is provided with the water flow guide portion 35 . , the tap water flowing down to the cleaning opening 20 can be guided along the inner surface of the main wall 22 and flowed down to the upper receiving portion 17a side to wash away the hair waste. In that case, the water flow guide portion 35 projecting rearwardly upward from the inner surface of the main wall 22 can be omitted, and the closing stopper 32 can be formed with an inclined surface received by the upper contact portion 34 .

When the interior of the hair dust chamber 16 is to be washed with water, the finger receiving portion 27 is pushed toward the hair dust chamber 16 to open the opening/closing body 26 and switch the guide body 21 to the guiding position. As shown in FIG. 6, the electric razor in this state is held by gripping the body case 1 with the razor head 2 facing obliquely downward, and the washing opening 20 is positioned at the downflow position of the tap water (washing water). The movable blade 6 is rotationally driven while running tap water into the hair waste chamber 16 to wash away the hair waste inside the hair waste chamber 16. - 特許庁When the center of the tap water flowing down is positioned above the finger receiving portion 27, most of the tap water flows and is guided along the main wall 22 of the guide body 21. It is possible to wash away the hair wastes that collide with the peripheral surface and adhere to the inner surface of the movable blade 6 and the inner surface of the fixed blade 7. - 特許庁Since the tap water colliding with the main wall 22 is diverted and guided by the group of vertical ribs 27a, the tap water colliding with the main wall 22 is diffused to eliminate collision with each other, and the tap water is diverted to the movable blade 6. You can flow and guide in an orderly manner. The tap water containing hair waste once enters inside the movable blade 6, and then is violently stirred by the rotating motion of the movable blade 6, collides with the movable blade 6 and the fixed blade 7, and flows through the group of blade holes into the outer blade 7. is discharged outside.

When the tap water flows down between the inner surface of the main wall 22 of the guide body 21 and the washing opening 20, the tap water is flow-guided along the inner surface of the main wall 22 of the guide body 21 and then flows through the water flow guide portion 35. The direction is guided toward the upper receiving portion 17a of the hair waste receiving portion 17, and the hair waste adhering to the upper receiving portion 17a is washed away directly. The tap water received by the vertical wall between the upper receiving portion 17a and the lower receiving portion 17b flows along the vertical wall toward the water flow guide portion 35 while washing away the hair waste adhering to the lower receiving portion 17b. , and finally wash away the hair waste adhering to the upper receiving portion 17a. During actual washing, the main body case 1, which is inclined obliquely downward, is rocked to the inclined upper side and the inclined lower side to alternately flow tap water to the movable blade 6 side and the upper receiving portion 17a side, thereby removing hair waste. It is possible to continuously wash away the hair waste in the chamber 16 and wash away the hair waste adhering to the movable blade 6 and the fixed blade 7 .

As described above, in the electric shaver of Example 1, the cleaning opening 20 is provided in the front wall of the fixed blade holder 8 facing the hair scrap receiving portion 17 , and the cleaning opening 20 is moved by the guide body 21 provided facing the cleaning opening 20 . The flowing tap water is flow-guided toward the hair waste receiving part 17.例文帳に追加According to such an electric shaver, tap water flowing down the washing opening 20 is surely flow-guided by the guide body 21 toward the hair waste receiving portion 17 at the bottom of the hair waste chamber 16, and is guided to the hair waste receiving portion 17. Accumulated hair dust and hair dust adhering to the movable blade 6 and the fixed blade 7 can be effectively washed away in a short time. Incidentally, in a conventional electric shaver that does not have the guide body 21, even if tap water is allowed to flow down through the cleaning water window, the subsequent flow path of the tap water depends on the internal structure of the hair waste chamber. It was not clear whether water was properly supplied to the bottom surface of the hair waste chamber where hair waste tends to accumulate, and it took a long time to wash the hair waste.

The guide body 21 also serves as an opening/closing body 26 for opening/closing the cleaning opening 20, and the opening/closing body 26 is made displaceable between a closed posture for closing the cleaning opening 20 and an open posture for opening the cleaning opening 20.例文帳に追加Further, in the state where the opening/closing body 26 is switched to the open position, the guide body 21 can flow and guide the tap water flowing down to the cleaning opening 20 toward the hair dust receiving portion 17.例文帳に追加According to such an electric shaver, compared with the case where the guide body 21 and the opening/closing body 26 are separately provided, the structure of the electric shaver can be simplified and the overall cost can be reduced accordingly.

A plate-shaped opening/closing body 26 is supported by a horizontal rotating shaft 23 so as to be swingable and openable so that it can be swingably displaced between an open position and a closed position. According to such an electric shaver, the cleaning opening 20 can be opened or closed simply by reciprocating the opening/closing body 26 . In addition, tap water is caused to flow down through the cleaning opening 20 with the cleaning opening 20 opened and the guide body 21 tilted, so that the tap water received by the guide body 21 is flow-guided toward the hair waste receiving portion 17. can. Incidentally, the opening/closing member 26 can be switched between an open posture and a closed posture by, for example, reciprocating sliding operation. can be simplified, and the cleaning opening 20 can be opened and closed accurately.

Since the opening/closing body 26 is supported by the rotating shaft 23 so that it can be opened and closed by swinging, the cleaning opening 20 is rotated with the part above the rotating shaft 23 when the opening/closing body 26 is in the open position. The portions below the shaft 23 are opened respectively, and tap water is supplied into the hair waste chamber 16 from the upper and lower opening portions of the cleaning opening 20, so that hair waste in the hair waste chamber 16 can be extensively washed. . For example, while tap water is caused to flow down into the hair waste chamber 16 from the portion above the rotation shaft 23, the tap water flowing through the portion below the rotation shaft 23 is used to remove the hair waste accumulated in the lower receiving portion 17b. can be washed off. Incidentally, in the case of a structure in which the lower part of the opening/closing body 26 is supported by the rotating shaft 23 so as to be able to swing open and close, and the opening/closing body 26 swings into the hair waste chamber 16 to open the cleaning opening 20, the lower support is used. Since the portion 17b is always covered with the opening/closing member 26, it is difficult to wash off the hair waste accumulated in the lower receiving portion 17b directly with tap water. Further, the opening/closing body 26 whose middle part in the vertical direction is supported by the rotating shaft 23 so as to be able to be opened and closed by swinging can be operated by pushing the portion above the rotating shaft 23 and the portion below the rotating shaft 23. , the opening/closing body 26 can be switched between the open position and the closed position, and there is also the advantage that a spring for urging the opening/closing body 26 to the open position or the closed position can be omitted.

Since the rotating shaft 23 is provided on the lower half side of the opening/closing body 26, the moment arm of the portion above the rotating shaft 23 when the opening/closing member 26 swings and opens and closes can be made larger than the moment arm of the portion below. . Therefore, by opening and closing the opening/closing body 26 by operating the upper half side, the opening/closing body 26 can be opened and closed more lightly. In addition, since the vertical length of the portion of the opening/closing body 26 below the rotating shaft 23 is made small, the projection dimension of the opening/closing body 26 exposed to the outside of the cleaning opening 20 when the opening/closing body 26 is opened is reduced. Therefore, tap water can be properly supplied while the water discharge part of the faucet is brought closer to the cleaning opening 20 by that amount.

The opening/closing body 26 is supported by the rotating shaft 23 provided on the lower half thereof so as to be openable and closable, and the finger receiving portion 27 for opening the opening/closing body 26 is formed on the upper half of the outer surface of the opening/closing body 26 to bulge out. , the opening operation of the opening/closing body 26 can be easily performed by pressing the finger receiving portion 27 . For example, when the upper half of the opening/closing body 26 is pushed in directly, since the rotating shaft 23 is provided on the lower half side of the opening/closing body 26, the upper part of the opening/closing body 26 when opened is , goes beyond the cleaning opening 20 and enters into the interior of the hair waste chamber 16 greatly. However, since the finger receiving portion 27 formed on the upper half of the outer surface of the opening/closing body 26 is located outside the upper portion of the opening/closing body 26, the finger receiving portion 27 is not exposed when the opening/closing body 26 is opened. There is no need to push into the inside of the waste chamber 16, and the opening operation of the opening/closing body 26 can be easily performed accordingly.

Since the finger receiving portion 27 is formed of a plurality of vertical ribs 27a elongated in the vertical direction, tap water that has collided with the opening/closing body 26 can be divided and guided in an orderly manner by the group of vertical ribs 27a. Therefore, the tap water colliding with the opening/closing member 26 is diffused to prevent the tap water from colliding with each other.

Since the moderation structure is provided between the peripheral wall of the cleaning opening 20 and the opening/closing body 26, the opening/closing body 26 can be reliably held at the closed position or the open position. Therefore, it is possible to reliably prevent the opening/closing body 26 from being erroneously opened during shaving, or from inadvertently moving to close due to the water flow during hair washing.

A detent structure with movable detent bodies 28 and 29 and a fixed detent body 30 provided between the partially arc-shaped detent arm 24 provided on the opening/closing body 26 and the peripheral wall of the cleaning opening 20 facing the swing locus of the detent arm 24. , the click structure can be provided on the facing surfaces of the click arm 24 and the peripheral wall of the cleaning opening 20, and the structure is efficient. In addition, since the movable detent bodies 28 and 29 and the fixed detent body 30 are engaged with each other, the position of the opening/closing body 26 can be reliably held in the closed posture and the open posture.

Since the opening/closing body 26 is provided with the closing stopper 32 and the opening stopper 31, the closing stopper 32 prevents the opening/closing body 26 from being erroneously swung beyond the closed position in the closing direction. erroneously swinging in the opening direction beyond the opening position can be prevented by the opening stopper 31. Incidentally, when the opening/closing body 26 is held in the closed position and the open position only by the moderation structure, the opening/closing body 26 is forced to swing beyond the closed position by misunderstanding or mischief, or the opening/closing body 26 is forced to swing beyond the closed position. is forced to swing beyond the open position. However, if the closing stopper 32 and the opening stopper 31 are provided on the opening/closing member 26, it is possible to reliably prevent erroneous operation due to misunderstanding or mischief as described above.

An opening stopper 31 is provided at the tip of the moderation arm 24, and a lower contact portion 33 for receiving the opening stopper 31 is provided on the peripheral wall of the washing opening 20. - 特許庁According to such a stopper structure, the opening stopper 31 can be provided using the detent arm 24 that constitutes the detent structure, and the lower contact portion 33 can be formed using the peripheral wall of the cleaning opening 20. There is no waste in the structure as a whole, and the simplification of the stopper structure contributes to cost reduction.

A closing stopper 32 is integrally provided on the upper part of the opening/closing body 26, and an upper contact portion 34 for receiving the closing stopper 32 is provided on the peripheral wall of the washing opening 20. - 特許庁According to such a stopper structure, the closing stopper 32 can be integrally formed using the opening/closing body 26, and the upper contact portion 34 can be formed using the peripheral wall of the cleaning opening 20, so that the structure as a whole is efficient and The simplification of the stopper structure contributes to cost reduction.

Since the upper edge of the closing stopper 32 is positioned above the hair dust receiver 17 when the opening/closing body 26 is switched to the open posture, the tap water flowing down into the washing opening 20 is prevented from flowing into the inner surface of the opening/closing body 26. , and flows down to the side of the upper receiving portion 17a to wash away hair waste.

Since the water flow guide part 35 is provided on the upper inner surface of the opening/closing body 26, the tap water flowing along the inner surface of the opening/closing body 26 is guided by the water flow guide part 35 in the state where the opening/closing body 26 is switched to the open posture. By changing direction and guiding toward the receiving portion 17, the hair waste accumulated in the hair waste receiving portion 17 can be directly washed away by the flowing action of the tap water. Therefore, compared to the conventional electric shaver which cleans the hair waste accumulated in the hair waste receiving portion 17 by simply immersing it in tap water, the hair waste accumulated in the hair waste receiving portion 17 can be removed in a short time. can be washed off effectively.

(Example 5) Figs. 10 to 12 show a flush electric shaver according to Example 5. Figs. In the electric shaver of Example 5, the opening/closing body 26 is formed by three louver plates 40 arranged adjacently in the vertical direction and supported so as to be able to swing open and close. I made it to double as 26. The louver plate 40 includes louver plates 41 and louver shafts 42 fixed to the left and right sides of the louver plate 41. By supporting the louver shafts 42 on the peripheral wall of the cleaning opening 20, each louver plate 41 can move forward and backward. 11(a)) and an open posture (state shown in FIG. 11(b)) in which each blade 41 is separated and tilted upward.

An interlocking structure is provided on the inner surface of the fixed blade holder 8 in order to interlock and open and close the louver plates 40 . As shown in FIG. 12, the interlocking structure consists of a fan-toothed pinion 43 fixed to the louver shaft 42 of each louver plate 40, a rack 44 that meshes with each pinion 43, and a slide knob 45 that reciprocates the rack 44. It is The rack 44 is guided and supported by the front wall of the fixed blade holder 8 so as to be vertically slidable. The slide knob 45 is fixed to the lower side surface of the rack 44 and is exposed through a slide window 46 opened in the front surface of the fixed blade holder 8 . When the slide knob 45 is slid downward along the slide window 46, the rack 44 is moved downward and the pinion 43 is rotated clockwise in FIG. 12, so that the louver plate 40 can be opened. Conversely, when the slide knob 45 is slid upward along the slide window 46, the louver plate 40 can be brought into the closing posture. In order to prevent the louver plate 40 from swinging beyond the closed posture, a lower contact portion 33 and an upper contact portion 34 are provided on the upper and lower surfaces of the cleaning opening 20, respectively, so that the louver plate 40 can be switched to the closed posture. At this time, the closing stopper 32 of the lower louver plate 40 and the closing stopper 32 of the upper louver plate 40 are received by the lower contact portion 33 and the upper contact portion 34 . The pinion 43 may be fixed to the wing plate 41 .

As described above, when the guide body 21 and the opening/closing body 26 are configured with a plurality of louver plates 40, the guide body 21 and the opening/closing body 26 can be made thinner. Further, when the louver plates 40 are switched to the open posture, the cleaning opening 20 is divided into four upper and lower stages by the three louver plates 40 . Therefore, tap water is allowed to flow down through the openings of each stage while rocking the main body case 1, which is tilted obliquely downward, to the upper and lower inclined sides during washing, thereby allowing the tap water to flow over a wide area of the hair waste chamber 16. It spreads rapidly, and the hair waste in the hair waste chamber 16 can be washed away to every corner. In addition, each louver plate 40 is linked so that it can be opened and closed by an interlocking structure comprising a pinion 43 fixed to each louver plate 40, a rack 44 meshing with each pinion 43, and a slide knob 45 for reciprocating the rack 44. The attitudes of the three louver plates 40 can be switched at the same time by simply sliding the slide knob 45 up and down, and can be held in the open attitude or the closed attitude. Therefore, as compared with the case where the attitude of each louver plate 40 is individually switched, it is possible to greatly save the trouble of switching the attitude.

(Example 6) Figs. 13(a) and 13(b) show a flush electric shaver according to Example 6. Figs. In the sixth embodiment, a rotating shaft 23 is provided at the lower portion of an opening/closing member 26 that also serves as a guide member 21, and the rotating shaft 23 is supported by a bearing hole 25, thereby supporting the opening/closing member 26 so as to be able to swing open and close. there is A closing spring 48 externally fitted on the rotating shaft 23 urges the opening/closing member 26 toward the closing position. The closing spring 48 is a torsion coil spring with one spring arm hooked on the inner surface of the opening/closing member 26 and the other spring arm hooked on the inner peripheral wall of the cleaning opening 20 . At the upper end of the plate-shaped opening/closing body 26, an inclined closing stopper 32 is formed in a rear rising shape. A recess 49 is formed in the front corner of the upper receiving portion 17a to receive the opening/closing body 26 in the open position.

In order to hold the opening/closing body 26 in the open posture against the urging force of the closing spring 48, a partially arcuate latch arm 50 is provided on the inner surface of the opening/closing body 26, and the latch arm 50 is engaged with the lower receiving portion 17b. A retaining latch structure 51 is provided.

In this state, the opening/closing body 26 is inclined upward from the washing opening 20 toward the hair dust receiving portion 17, and the opening/closing body 26 enters the recess 49, and the upper edge of the closing stopper 32 touches the upper surface of the upper receiving portion 17a. is coming. Therefore, the tap water that has flowed down to the cleaning opening 20 is flow-guided by the outer surface of the opening/closing body 26, flows toward the upper surfaces of the movable blade 6 and the upper receiving portion 17a, and accumulates in the upper receiving portion 17a due to the flowing water. It is possible to reliably and quickly wash away the hair waste. After cleaning is completed, the opening/closing body 26 is pushed in again to release the latch structure 51 from engaging and holding, so that the opening/closing body 26 is returned to the closed posture by the urging force of the closing spring 48 . Note that the latch arm 50 and the latch structure 51 can be omitted, and in that case, it is preferable to hold the opening/closing body 26 in the open posture with a fingertip and wash it with water.

The lower part of the opening/closing body 26 is supported by a horizontal rotating shaft 23 so as to be swingably opened and closed, and a closing spring 48 swings and biases the opening/closing body 26 toward the closed posture. According to such an opening/closing structure, the cleaning opening 20 can be closed and held by the opening/closing member 26 in a normal state. Since it can be pushed back to the closed posture, it is possible to prevent the hair dust from scattering out of the washing opening 20 well. Further, after the cleaning is finished, the latch structure 51 is operated to release the position holding state of the opening/closing body 26 held in the open position, and the opening/closing body 26 is moved to the closed position by the urging force of the closing spring 48. can be returned.

(Example 7) Figs. 14 and 15 show a flush electric shaver according to Example 7. Figs. In Example 7, the guide member 21 is provided integrally with the inner surface of the flat opening/closing member 26 . The opening/closing member 26 is supported by a rotating shaft 23 provided on the upper portion thereof so as to be capable of being opened and closed by swinging. The opening/closing member 26 swings upward from the closing posture to close the cleaning opening 20 and opens the cleaning opening 20 . It can be oscillatingly displaced to and from the open posture, and is urged to oscillate toward the open posture by an open spring 53 . The guide body 21 is formed of a curved plate, is arranged separately on the diagonal upper part of the inner surface of the opening/closing body 26, and is integrated via a pair of left and right support arms 54 provided between the facing surfaces of both. When the opening/closing body 26 switches to the closed position, the guide body 21 faces the peripheral surface of the movable blade 6 and maintains the standby position (the state shown in FIG. 14(a)). Further, when the opening/closing body 26 swings open by the opening spring 53, the guide body 21 swings downward in conjunction with the opening/closing body 26 and switches to the guiding posture (the state shown in FIG. 14(b)). In this state, the guide body 21 is tilted upward in a guiding posture in which the curved lower portion is positioned at the cleaning opening 20 and the curved upper portion covers the front corner of the upper receiving portion 17a.

In order to engage and hold the opening/closing member 26 in the closed posture against the biasing force of the opening spring 53, a switching member 55 is provided on the lower peripheral wall of the cleaning opening 20, and the switching member 55 is provided on the lower inner surface of the opening/closing member 26. A claw body 56 corresponding to is provided in a lying L shape. The switching tool 55 is integrally provided with an L-shaped engaging piece 57 that engages and disengages with the pawl 56 of the opening/closing body 26 and an operation knob 58 that engages and disengages the engaging piece 57 from the pawl 56 . . By guiding the engaging piece 57 so as to be slidable in the left and right direction by a guide groove 59 formed in the fixed blade holder 8, the switching tool 55 is moved to the slide position (FIG. 14(a)) where the engaging piece 57 engages with the pawl 56. ) and a sliding position where the engaging piece 57 is disengaged from the pawl 56 . Further, the switching member 55 is urged by a return spring 60 toward the slide position where the engaging piece 57 engages with the pawl 56 . The operating knob 58 is exposed on the front surface of the fixed blade holder 8 .

When the hair waste in the hair waste chamber 16 is to be washed with water, the operation knob 58 is slid leftward in FIG. let go to At the same time when the engaging piece 57 is released from the claw body 56, the opening/closing body 26 receives the urging force of the opening spring 53 and swings upward to switch to the open posture.

Next, with the razor head 2 facing obliquely downward, the body case 1 is gripped and held, and the washing opening 20 is positioned at the downflow position of the tap water. 6 is rotationally driven to wash away the hair waste inside the hair waste chamber 16. - 特許庁At this time, the tap water flowing along the outwardly projecting curved surface of the guide body 21 is guided toward the movable blade 6 and the upper receiving portion 17a, and the tap water flowing along the inwardly recessed curved surface of the guide body 21 is , is guided mainly toward the upper receiving portion 17a to wash away hair waste accumulated in the upper receiving portion 17a. When the opening/closing member 26 is switched to the open posture, the opening surface of the washing opening 20 is opened widely, so that tap water is caused to flow down to a desired position of the guide member 21 while clearly recognizing the flow-down position, thereby removing hair waste. Washing can be effectively performed. The switching tool 55 may have a structure in which the operation knob 58 is vertically slid to engage and disengage the engaging piece 57 and the pawl 56 .

In Embodiment 7, the opening/closing body 26 is provided integrally with the inner surface of the guide body 21 so that the guide body 21 can change its attitude between the waiting attitude and the guiding attitude in conjunction with the opening/closing operation of the opening/closing body 26 . Further, in a state where the opening/closing member 26 opens the cleaning opening 20 , the guide member 21 switches to the guiding posture, so that the cleaning water that has flowed down to the cleaning opening 20 can be flow-guided toward the hair dust receiving portion 17 . Thus, when the guide body 21 and the opening/closing body 26 are separately provided, the guide body 21 is configured specifically for the function of guiding the tap water toward the hair dust receiving portion 17, and the opening/closing body 26 can be specially configured to open and close the cleaning opening 20, the flexibility of the shape and structure of the guide body 21 and the opening/closing body 26 is increased compared to the case where the guide body 21 also serves as the opening/closing body 26. Since the guide body 21 in the state of being switched to the guiding posture is formed of an upwardly curved curved plate, the tap water flowing down into the washing opening 20 is washed away by the upper curved surface and the lower curved surface of the guide body 21 to remove hair and debris. It can be flow-guided toward the receiving portion 17, and the hair waste accumulated in the upper receiving portion 17a of the hair waste receiving portion 17 can be reliably and quickly washed away.

Further, in the seventh embodiment, the opening spring 53 oscillates the opening/closing body 26 toward the open posture, and the peripheral wall of the cleaning opening 20 moves the opening/closing body 26 to the closed posture against the urging force of the opening spring 53 . A switching tool 55 is provided for engaging and holding. The switching tool 55 is integrally provided with an engaging piece 57 and an operating knob 58 , and by displacing the operating knob 58 , the engaging piece 57 can be engaged with and disengaged from the pawl 56 of the opening/closing body 26 . According to such an opening/closing structure, when the operation knob 58 is operated to disengage the engaging piece 57 from the claw body 56, the opening/closing body 26 receives the biasing force of the opening spring 53 and switches to the open position. That is, it is possible to switch the opening/closing member 26 from the closed posture to the open posture with a small amount of time and effort, such as one-touch operation of the operation knob 58 . Further, the switching member 55 is guided and supported by the peripheral wall of the cleaning opening 20 so as to be reciprocally slidable. As compared with the case where is configured in the shape of a push button, it is possible to prevent the switch 55 from being erroneously switched. Further, the switching tool 55 is arranged below the cleaning opening 20 and is supported by the peripheral wall of the cleaning opening 20 so as to be slidable to the left and right. Since the switch 58 can be easily switched, the trouble of changing the grip position of the main body case 1 in order to switch the operation knob 58 can be saved.

(Example 8) Figs. 16 and 17 show a flush electric shaver according to Example 8. Figs. In Example 8, the opening/closing body 26 and the guide body 21 are individually formed as independent parts, and the two are connected by connecting shafts 63 provided on both sides of the guide body 21 so as to be relatively rotatable. The opening/closing body 26 is supported at its lower portion by a rotating shaft 23, and swings downward from the closed posture (state shown in FIG. 16A) to close the cleaning opening 20 and opens the cleaning opening 20. 16(b)) and a stored posture (state shown in FIG. 17) in which the opening/closing member 26 swings obliquely downward beyond the open posture. In order to allow such opening and closing swinging of the opening/closing body 26, the lower peripheral surface of the cleaning opening 20 is formed in a shape that slopes forward downward. A grip portion 64 is integrally provided on the upper portion of the opening/closing member 26 , and a flat receiving wall 65 that defines the rotation range of the guide member 21 is formed on the lower portion of the opening/closing member 26 .

The guide body 21 is formed in a flat plate shape, and a restriction wall 66 supported by the receiving wall 65 is formed on the side of the connecting end with the opening/closing body 26 . A free end of the guide body 21 is formed with a stopper surface 67 for defining the swing limit. A connecting spring 68 is provided between the opening/closing member 26 and the guide member 21. The connecting spring 68 urges the guide member 21 to rotate counterclockwise in FIG. 16(a). In this way, the guide body 21 urged to swing by the connecting spring 68 receives the restriction wall 66 by the receiving wall 65, so that when the opening/closing body 26 is in the closed posture, it is It is held in a standby posture that bends into a dogleg shape. Further, the guide body 21, which is inclined downward in the standby posture, is provided at a position lower than the upper surface (upper receiving portion 17a) of the hair dust receiving portion 17, and receives a part of the hair dust falling into the lower receiving portion 17b. ing.

In order to allow the guide body 21 to swing together with the opening/closing body 26, the lower receiving portion 17b is formed in a partial arc shape, and a stopper surface 67 is provided on the upper end of the lower receiving portion 17b (the front portion of the hair clip receiving portion 17). A stepped portion 69 for receiving the is provided. Further, as shown in FIG. 17, an engaging rib 70 is projected from the front portion of the main body case 1, and the handle portion 64 of the opening/closing member 26 swinging downward to the retracted posture is engaged with the engaging rib 70. As a result, the opening/closing member 26 can be held in the retracted posture.

When the opening/closing body 26 in the closed posture is swung downward and opened by applying a fingertip to the grip portion 64, the guide body 21 swings upward together with the opening/closing body 26, and the opening/closing body 26 is opened. In the state of being switched to the posture, the stopper surface 67 is received by the stepped portion 69 of the lower receiving portion 17b, and is held in a guiding posture inclined upward toward the hair dust receiving portion 17b. When the opening/closing member 26 is further opened by swinging it downward, the opening/closing member 26 swings downward while resisting the spring force of the connecting spring 68, and assumes the retracted posture. That is, the opening/closing body 26 swings open from the open position to the retracted position while resisting the biasing force of the connecting spring 68 while leaving the guide body 21 held in the guiding posture. The receiving wall 65 in this state receives the round shaft portion separated from the regulating wall 66 and continuing to the connecting shaft 63 . In this way, by engaging the handle portion 64 with the engaging rib 70 while the opening/closing body 26 is swinging downward, the opening/closing body 26 can be held in the retracted posture.

After that, by pouring tap water through the washing opening 20, the hair waste adhering to the upper receiving portion 17a of the hair waste receiving portion 17 and the guide body 21 can be directly washed away by the flowing action of the tap water. can. After washing with water, the interior of the hair waste chamber 16 is dried, and then the handle portion 64 is separated from the engagement rib 70, so that the opening/closing body 26 is flipped up and swung by the biasing force of the connecting spring 68 to the closed posture. can be returned to

As described above, if the opening/closing member 26 is configured to swing open from the open position to the retracted position, the cleaning opening 20 can be opened, and the opening/closing member 26 can be retracted below the cleaning opening 20. Since it is held at that position, it is possible to clean hairs more accurately while clearly viewing the state of tap water flowing down the cleaning opening 20 and the cleaning state of the hair waste chamber 16 . Further, since the guide body 21 switched to the guiding posture faces the washing opening 20 in a state of being inclined upward toward the upper receiving portion 17a of the hair dust receiving portion 17, the tap water flows directly down to the guide body 21. As a result, the hair waste adhering to the guide body 21 can be reliably washed away by the flowing action of the tap water.

In this embodiment, the total swing angle of the opening/closing member 26 from the closed posture to the retracted posture is about 165 degrees, but the total swing angle of the open/close member 26 between the closed posture and the retracted posture is 90 degrees or more. It is sufficient to set If the total swinging angle of the opening/closing body 26 is 90 degrees or more, in the state where the opening/closing body 26 is swung open from the open position to the retracted position, the cleaning opening 20 is opened and the opening/closing body 26 is further opened in the same manner as described above. It can be retracted forward of the cleaning opening 20 . Therefore, it is possible to clean the hairs accurately while clearly observing the state of tap water flowing down the cleaning opening 20 and the state of cleaning in the hair waste chamber 16 .

The opening/closing body 26 and the guide body 21 are separately formed as independent components, and the two are connected by connecting shafts 63 provided on both sides of the guide body 21 so as to be relatively rotatable. Further, the downwardly inclined guide body 21 in the standby posture is provided at a position lower than the upper receiving portion 17a of the hair waste receiving portion 17 so as to receive a part of falling hair waste. After that, the guide body 21 swings upward accompanying the opening/closing body 26 swinging from the closed position to the open position, and switches from the waiting position to the guiding position inclined upward toward the hair dust receiver 17. made it According to such a guide structure, since the side of the guide body 21 that receives the hair waste can face the cleaning opening 20 during hair waste washing, tap water is allowed to flow directly down the guide body 21, thereby allowing the guide body 21 to flow downward. The hair waste adhering to the body 21 can be washed off directly by the flowing action of tap water.

A connecting spring 68 is provided between the opening/closing body 26 and the guide body 21, and while the opening/closing body 26 is switched from the closing posture to the opening posture, the guide body 21 swings together with the opening/closing body 26 to shift from the waiting posture to the guiding posture. I tried to switch to Further, when the opening/closing body 26 is switched to the open position, the stopper surface 67 provided on the guide body 21 is received by the stepped portion 69 so that the guide body 21 can be held in the guiding position. With such an opening/closing structure and a guide structure, the opening/closing body 26 can be swung from the open posture toward the retracted posture while reliably preventing the guide body 21 from swinging beyond the guide posture.

The opening/closing body 26 is designed to swing open from the open position to the retracted position while resisting the urging force of the connecting spring 68 while the guide body 21 is left in the guiding posture. According to such an opening/closing structure, the entire swinging angle of the opening/closing body 26 can be freely set without being restricted by the swinging angle of the guide body 21, and the opening/closing body 26 interferes with the cleaning of hair wastes. can be more reliably prevented from becoming

The guide frame 73 is formed of a frame body having a U-shaped cross section that opens forward, and an accommodation groove 75 for receiving the guide body 21 switched to the standby posture is provided on the inner surface thereof. The upper and lower walls of the guide frame 73 are formed as guide walls 76 and 77 for sliding and guiding the guide body 21 back and forth. there is A finger receiving portion 27 having an L-shaped cross section is formed on the front surface of the opening/closing body 26 .

When the opening/closing body 26 is in the closed posture, the guide body 21 is inserted into the accommodation groove 75 and the front end of the slide groove 74 is received by the rotating shaft 23 . In this state, the guide body 21 and the opening/closing body 26 are pulled out forward of the cleaning opening 20 by applying the fingertips to the finger receiving portion 27, and the opening/closing body 26 is moved while the rear end of the slide groove 74 is in contact with the rotating shaft 23. , the opening/closing body 26 can be switched to the open position shown in FIG. 18(b). Further, in conjunction with the downward swinging of the opening/closing body 26 , the guide body 21 switches from the waiting posture to the guiding posture, and the opening stopper 31 on the lower surface of the guide body 21 is received by the lower contact portion 33 . When the guide body 21 and the opening/closing body 26 are drawn forward, the guide body 21 is slidably guided by the upper and lower guide walls 76 and 77 and the rotating shaft 23 .

As described above, with the opening/closing member 26 in the open position and the guide member 21 in the guiding position, when tap water is allowed to flow down the cleaning opening 20 , the tap water flows into the hair dust receiver 17 deep inside the cleaning opening 20 . can be directly flowed to properly wash away the hair waste adhering to the upper receiving portion 17a. Further, when the opening/closing body 26 is in the open position, part of the opening/closing body 26 and the guide body 21 protrude outside the cleaning opening 20, and the front and lower sides of the cleaning opening 20 can be largely opened. It is possible to accurately wash the hair while clearly observing the state of running tap water against the hair and the state of washing in the hair waste chamber 16. - 特許庁When the guide body 21 is switched to the guiding posture, the opening stopper 31 at the free end of the guide body 21 is received by the lower abutting portion 33 and inclined upward toward the upper receiving portion 17a of the hair waste receiving portion 17. Since the semicircular part of the free end is flush with the guide wall 76 on the upper side, tap water that has flowed down the guide body 21 can reliably flow to the upper surface side of the guide wall 76 . When the opening/closing body 26 is switched to the closed position, the guide walls 76 and 77 support the guide body 21 so as not to move up and down.

(Example 10) Figs. 19 and 20 show a flush electric shaver according to Example 10. Figs. In the tenth embodiment, a rubber sheet-like closing wall 80 formed in a laterally long fan shape, sliding walls 81 formed on both sides of the closing wall 80, and opening/closing finger ribs 82 formed on the front surface of the sliding wall 81 are provided. so that the guide body 21 also serves as an opening/closing body 26 for opening/closing the cleaning opening 20. - 特許庁The slide wall 81 is guided and supported by guide walls 83 provided on the inner surfaces of the left and right sides of the cleaning opening 20 so as to be slidable to open and close, and can be opened and closed within the formation range of the guide walls 83 . When the slide wall 81 is slid open and closed, the upper and lower ends of the wall 81 are received by the inner wall of the cleaning opening 20 to prevent the slide wall 81 from slipping forward from the cleaning opening 20.例文帳に追加

As shown in FIG. 19A, the guide member 21 functions as an opening/closing member 26 that closes the cleaning opening 20 when the closing wall 80 is in a flat sheet state. 19(b) and 19(b) and FIG. 19(b) and FIG. As shown in 20, a curved gutter 84 can be made to appear to switch to the guiding posture. That is, the opening/closing body 26 can be switched to the open position. In the state where the guide body 21 is switched to the guiding posture, the tap water that flows down into the washing opening 20 can be received by the curved gutter-shaped portion 84 and flow-guided toward the upper receiving portion 17a of the hair waste receiving portion 17. . When the finger hook ribs 82 are returned to both end positions of the cleaning opening 20 after the cleaning is finished, the closing wall 80 returns to the sheet state and the cleaning opening 20 can be closed from the inner surface side.

As described above, according to the guide structure and the opening/closing structure in which the cleaning opening 20 can be opened/closed by the guide body 21 which also serves as the opening/closing body 26, there is no need to provide the opening/closing body 26 separately from the guide body 21. , the closing wall 80 can be elastically deformed to reveal a gutter-like portion 84 for guiding the tap water. Therefore, compared to the case where the opening/closing body 26 and the guide body 21 are provided separately, the overall structure of the opening/closing structure and the guide structure can be significantly simplified and the cost can be reduced. Further, according to such a guide structure, by sliding at least one of the finger hook ribs 82 toward the other, the right and left intermediate portions of the guide body 21 are elastically deformed inward to reveal the gutter-shaped portion 84. At the same time, since the cleaning opening 20 can be opened, the tap water that has flowed down to the cleaning opening 20 can be flowed and guided to the hair waste receiving section 17 more reliably by the gutter-like portion 84. - 特許庁Since the closing wall 80 is formed in a laterally long fan shape, the upper end of the gutter-shaped portion 84 is brought close to the upper receiving portion 17a of the hair dust receiving portion 17, and the tap water flowing down into the washing opening 20 is drained into the gutter-shaped portion. At 84 further reliable flow guidance is provided. As described above, it is preferable that the closing wall 80 is formed in the laterally elongated fan shape, but if necessary, the closing wall 80 may be formed in the laterally elongated rectangular sheet shape.

(Example 11) Figs. 21 and 22 show a flush electric shaver according to Example 11. Figs. In the eleventh embodiment, the guide body 21 is provided in the upper half of the horizontally long plate-like body, the opening/closing body 26 is provided in the lower half of the plate-like body, and the guide body 21 and the opening/closing body 26 are integrally provided. . The guide body 21 has a water passage opening 87 formed in the upper half of its plate-like body, and a two-level louver wall 88 provided therein. The opening/closing body 26 occupies the lower half of a horizontally elongated plate-like body, and a grip portion 64 is formed to bulge at the center of its front surface. In order to slide the guide body 21 and the opening/closing body 26 linearly, a slide recess 89 is formed in front of the cleaning opening 20 and guide grooves 90 are provided on both sides of the recess 89 . In addition, slide pieces 91 are provided at a total of four positions on both left and right sides of the guide body 21 and on both left and right sides of the opening/closing body 26, and these slide pieces 91 are guided and supported by guide grooves 90 so as to freely slide vertically.

As shown in FIG. 21(a), when the opening/closing body 26 is switched to the open position, the water passage opening 87 and the louver wall 88 of the guide body 21 face the cleaning opening 20 and assume the guiding position. The tap water flowing down toward the opening 87 can be deflected and guided obliquely upward by the louver wall 88 to flow toward the upper receiving portion 17 a of the hair dust receiving portion 17 . 21(b) and 22, when the opening/closing body 26 is switched to the closed posture, the cleaning opening 20 is closed by the opening/closing body 26 so that hair waste does not flow out of the cleaning opening 20. can be prevented.

As described above, according to the guide structure and the opening/closing structure in which the guide body 21 and the opening/closing body 26 are integrally provided and the cleaning opening 20 is opened/closed by vertically sliding the guide body 21 and the opening/closing body 26, the opening/closing body 26 and Compared to the case where the guide body 21 is provided separately, the overall structure of the opening/closing structure and the guide structure can be significantly simplified and the cost can be reduced. In addition, since the opening/closing member 26 is slid up and down to switch between the closed posture and the open posture, the posture is not changed just by touching the opening/closing member 26 or the guide member 21 by mistake. Switching can be avoided as much as possible.

(Example 12) Fig. 23 shows a flush electric shaver according to Example 12. Figs. In Example 12, similarly to Example 11, the guide body 21 is provided in the upper half of the plate-like body, and the opening/closing body 26 is provided in the lower half of the plate-like body. The four slide pieces 91 provided on the guide body 21 and the opening/closing body 26 are guided and supported by the guide grooves 90 provided on both sides of the recess 89 so as to be vertically slidable. . Further, a laterally elongated rib-shaped grip portion 64 provided on the front surface of the opening/closing body 26 is projected forward from the cleaning opening 20 . Furthermore, the front-rear thickness of the guide body 21 is set larger than the front-rear thickness of the opening/closing body 26 to increase the front-rear length of the louver wall 88 .

As shown in FIG. 23( a ), when the opening/closing body 26 is switched to the closed posture, the cleaning opening 20 is closed by the opening/closing body 26 to prevent the hair waste from coming out of the cleaning opening 20 . Further, as shown in FIG. 23(b), when the opening/closing body 26 is switched to the open position, the guide body 21 assumes the guiding position, and the water flow opening 87 and the louver wall 88 face the cleaning opening 20. The tap water flowing down toward the water passage opening 87 can be deflected and guided obliquely upward by the louver wall 88 to flow toward the upper receiving portion 17 a of the hair dust receiving portion 17 . At this time, since the directivity of the tap water flow-guided by the louver wall 88 can be enhanced by the length of the louver wall 88, the tap water flowing down toward the water passage opening 87 can be received. It can be delivered more accurately toward the portion 17a.

As described above, according to the guide structure and the opening/closing structure in which the guide body 21 and the opening/closing body 26 are integrally provided and the cleaning opening 20 is opened/closed by vertically sliding the guide body 21 and the opening/closing body 26, the opening/closing body 26 and Compared to the case where the guide body 21 is provided separately, the overall structure of the opening/closing structure and the guide structure can be significantly simplified and the cost can be reduced. In addition, as in the eleventh embodiment, the posture is not changed even if the fingertip accidentally touches the grip portion 64 or the opening/closing member 26, and the posture switching due to misunderstanding can be avoided as much as possible. Further, since the guide body 21 and the opening/closing body 26 are accommodated in the slide recess 89 on the inner surface of the cleaning opening 20, even when the main body case 1 is subjected to an external impact such as a drop impact or a collision impact, the guide body 21 and the opening/closing body 26 are prevented from opening and closing. Direct external impact on the body 26 can be effectively prevented.

(Example 13) Figs. 24 and 25 show a flush electric shaver according to Example 13. Figs. In the thirteenth embodiment, the guide body 21 and the opening/closing body 26 are provided in the upper and lower halves of a disk-shaped plate-like body, and the center shaft 93 provided on the rear surface of the plate-like body is positioned below the washing opening 20. The guide body 21 can be switched between the standby position and the guide position by rotating and sliding the opening/closing body 26. The cleaning opening 20 is formed in a semicircular shape, and when the opening/closing member 26 is positioned below the cleaning opening 20 as shown in FIG. I tried to come. The guide body 21 and the opening/closing body 26 are accommodated in a circular slide concave portion 89 so as to be flush with the front wall of the fixed blade holder 8, and a rib-shaped grip portion 64 provided on the front surface of the opening/closing body 26 is rotated. By doing so, the posture can be switched.

As described above, the guide body 21 and the opening/closing body 26 are formed in the upper and lower halves of the disk-shaped plate-like body, and the guide body 21 and the opening/closing body 26 are separated by rotating the handle portion 64 halfway. According to the guide structure and the opening/closing structure for switching the posture, compared with the case where the guide body 21 and the opening/closing body 26 are reciprocatingly slid to switch the posture, the overall structure is simplified and the cost of the guide structure and the opening/closing structure is reduced. can be In addition, since the tap water flowing down toward the semicircular water passage opening 87 is guided by the plurality of louver walls 88, more water is directed toward the left and right center of the hair dust receiving portion 17 where hair dust tends to accumulate. By flowing and guiding the tap water, it is possible to more reliably wash the hair waste accumulated in the hair waste receiving portion 17.例文帳に追加Furthermore, since it is possible to prevent the opening/closing body 26 from rotating and changing its posture when the fingertip accidentally touches the opening/closing body 26 or the guide body 21, it is possible to more reliably avoid the switching of the posture due to a misunderstanding. can.

(Example 14) Fig. 26 shows a flush electric shaver according to Example 14. In Example 14, the inner surface of the cleaning opening 20 is closed with a filter 98 that blocks passage of hair waste but allows passage of tap water. The filter 98 is made of nickel or nickel alloy metal mesh formed by electroforming, and fine holes are regularly formed over the entire surface of the sheet-like filter 98 . Five louver frames 95 forming the guide body 21 are arranged in a multi-stage manner on the inner surface of the cleaning opening 20 , and a filter 98 is fixed to a filter concave portion 94 on the inner surface of the louver frame 95 .

The upper portion of the filter 98 is closely connected to the fixed blade 7 so as to be heat-transferable, and this connecting portion is indicated by reference numeral 96 . If necessary, the guide body 21 can be configured by stacking a plurality of metal meshes having different hole shapes and arrangement patterns of fine holes.

As described above, when the inner surface of the washing opening 20 is closed with the filter 98, the tap water can be introduced into the hair waste chamber 16 to wash the hair waste simply by flowing the tap water down the washing opening 20. Since it can be done, the hair waste can be washed with water with less effort. Since the filter 98 is arranged on the inner surface of the louver frame 95 (the guide body 21), the louver frame 95 can block and protect the filter 98 from coming into contact with other objects. The louver frame 95 can be used to change direction and guide it obliquely upward so that it can flow toward the upper receiving portion 17 a of the hair dust receiving portion 17 . In addition, since there is no movable part, there is no room for malfunction due to posture switching, and the reliability of the guide structure can be improved. Furthermore, when the filter 98 is made of metal mesh, the guide structure can be simplified and the cost can be reduced, and the durability of the filter 98 can be improved compared to the case where the filter 98 is made of other materials. . Since the upper part of the filter 98 is tightly connected to the fixed blade 7, the heat of the fixed blade 7 can be conducted to the filter 98 and radiated, and even when the time required for shaving takes a long time, the fixed blade can be used. 7 can be well prevented from becoming hot.
