According to this, since the fixing portion 112, the elastic arm 114, and the pressing portion 113 are formed in a frame shape, the structural strength of the pressing body 111 can be increased. As a result, the elastic arm 114 can be elastically deformed flexibly, so that an accurate position holding function and a clear moderation function can be exhibited.

  The fixing portion 112 of the pressing body 111 can be stably fixed as the outer shape thereof is formed larger, and the elastic arm 114 can be elastically deformed more flexibly. However, the space for fixing the fixing portion 112 is increased accordingly. This requires a large charger. On the other hand, when the fixing portion 112 is fixed to the charger main body 18 with the drainage port 94 of the bottom wall 49 facing the channel opening 115 of the fixing portion 112 formed in an endless annular shape as in the present invention, the fixing portion While the outer shape of 112 is enlarged, the central portion of the fixed portion 112 that becomes a dead space can be used as a flow path through which drainage passes. Accordingly, the entire charger can be made compact while allowing the elastic arm 114 to be elastically deformed more smoothly.

  When a pair of elastic arms 114 and a pressing portion 113 are provided on the fixing portion 112 so as to face each other with the fixing portion 112 therebetween, the drain tray 95 is attached to the support wall 110 at two locations. Since it can be pushed downward, it is possible to more reliably prevent the drain tray 95 from rattling in the vertical direction. In addition, a more accurate position holding function and a clear moderation function can be exhibited.

  The charger main body 18 is provided with a drain tube 96 that guides the water drained from the drain port 94 to the drain tray 95, and when the fixing portion 112 is fixed to the drain tube 96, the structure of the charger Since the fixing portion 112 can be supported and fixed by the charger body 18, the pressing body 111 can be fixed more firmly. Therefore, a more accurate position holding function and moderation function can be exhibited.

  The drainage cylinder 96 is formed in a stepped cylinder shape, a circular fixed seat 116 is provided on the outer peripheral surface of the cylinder 96, and the pressure body 111 is fitted to the drainage cylinder 96 so that the flow path opening 115 is fitted to the drainage cylinder 96. It is possible to adopt a form in which the fixed portion 112 of 111 is fixed to the fixed seat 116. According to this, the fixing portion 112 is supported and fixed while restricting movement of the drainage cylinder 96 in the direction orthogonal to the cylinder axis, so that the pressing body 111 can be fixed more firmly.

  The mounting of the electric razor on the mounting portion 21 can be performed by the following procedure. First, the electric razor is set in an inverted posture in which the razor head 2 is positioned on the lower side with its front face directed to the front of the charger. In this state, the electric razor is inserted from above to the bottom of the mounting portion 21 through the wide front portion of the upper opening, and the electric razor is used with the tip (lower side) of the razor head 2 as a fulcrum as shown by the arrow in FIG. Is tilted rearward, and the main body 1 is moved to the rear narrow portion of the upper opening. As a result, the electric razor is mounted at an appropriate charging position of the mounting portion 21. The electric razor mounted at the charging position is such that the razor head 2 is moved forward by a pair of left and right positioning ribs indicated by reference numeral 48 in FIGS. 3 and 5, and the tip of the razor head 2 is mounted at the mounting portion 21. Is received by the bottom wall 49 (bottom housing 26). Further, the main body 1 is leaning against the rear wall surface 50 (wall surface) of the mounting portion 21 in a state where the entire electric razor is inclined backward. The main body 1 faces the rear wall surface (wall surface) 50 of the mounting portion 21 and the left wall surface (wall surface) 51 and the right wall surface (wall surface) 52 in the rear narrow side portion of the upper opening. The upper end portion of 52 is in contact with the outer surface of the main body 1, and movement in the rear direction and the left-right direction of the main body 1 is restricted.

  The outer housing 24, the inner housing 25, and the upper housing 27 constituting the housing 20 are made of a plastic molded product. The bottom housing 26 constitutes a bottom wall 49 of the mounting portion 21 and is formed of a molded product made of an elastomer (elastic body) that is rich in flexibility and heat resistance and has good thermal conductivity. By using an elastomer as the material forming the bottom housing 26, the impact applied to the razor head 2 when the electric razor is received by the bottom wall 49 of the mounting portion 21 is mitigated, and the surface of the cutting blade portion 3 is scratched. Etc. can be prevented.

  The charging, drying, and sterilization operations by the charger are configured to be executed when the electric razor is mounted at an appropriate charging position of the mounting unit 21. Therefore, one detection switch 55 that detects that the electric razor is properly mounted at the charging position of the mounting portion 21 is disposed at the center of the rear wall surface 50 of the mounting portion 21 in the vertical direction. As shown in FIG. 5 and FIG. 6, the detection switch 55 includes a contact body 56 that is guided so as to be freely retractable on the rear wall surface 50 of the mounting portion 21, a switch body 57 that is turned on and off by the contact body 56, An urging member 58 for advancing and urging the contact body 56 toward the electric razor attached to the portion 21 is provided. The switch body 57 is configured by a micro switch, and a movable spring 58 that performs a snap action of an actuator portion 59 of the switch functions as an urging member. When the urging force for advancing and urging the contact body 56 with only the movable spring 58 is insufficient, an urging member 58 made of a compression coil spring or a leaf spring may be separately provided. When the switch body 57 is switched from the off state to the on state, the control board 31 performs charging, drying, and sterilization operations.

The switch body 57 is held and fixed inside a square box-shaped switch case 62 whose front surface is open, and the switch case 62 is fixed to the inner housing 25 with screws (not shown). The contact body 56 includes a curved plate-shaped contact base 63 in which a central portion in the vertical direction swells forward, and a pair of upper and lower connecting walls 64 extending rearward from the upper and lower ends of the contact base 63. Yes. Guide claws 65 are respectively formed on the upper and lower surfaces of the switch case 62, and the guide claws 65 are engaged with guide grooves 66 formed in the connecting wall 64. With these guide claws 65 and guide grooves 66, the contact body 56 is supported so as to be able to move back and forth in the front-rear direction with respect to the switch base 62, and the amount of movement in the retracted direction (front-back direction) is restricted. The contact body 56 is disposed in a state of being fitted into a switch opening 67 formed in the rear wall surface 50 of the inner housing 25, and the contact body 56 can also be freely moved out of the inner peripheral surface of the switch opening 67. Guidance is supported. In the present embodiment, the switch body 57 is configured by a micro switch. However, the switch body 57 can be configured by a tact switch that is pushed in at the retracting end of the contact body 56. In this case, the contact body 56 may be urged in the advance direction by an urging member 58 such as a compression coil spring or a leaf spring.

  The front surface of the contact base 63 is a contact portion with which the electric razor contacts, and the contact portion is formed with a plurality of ribs 68 with rounded tips extending in the vertical direction (the direction in which the electric razor is inserted). Yes. The rear surface upper end portion of the main body 1 comes into contact with the contact surface, and the contact body 56 is pushed backward. Thus, if the contact part of the contact body 56 which comprises the detection switch 55 is comprised with the some rib 68 extended to an up-down direction, the contact area of an electric razor and a contact part can be made as small as possible. Thereby, the damage by the friction with the electric razor and the contact part at the time of attachment or detachment can be suppressed. Further, by rounding the tip of the rib 68, the contact area can be further reduced, and the damage of the main body 1 due to the contact friction between the main body 1 and the rib 68 can be further reduced. In the case of a charger in which an electric razor washed with water is attached to the attachment portion 21 as in this embodiment, the water adhering to the contact body 56 is allowed to flow downward through the adjacent ribs 68 and 68. Therefore, the malfunction of the detection switch 55 due to the accumulation of water around the detection switch 55 can be prevented, and the safety of the charger can be improved. If the plurality of ribs 68 are formed so as to cross the direction in which the electric razor is inserted, the electric razor may be caught by the ribs 68 when the electric razor is attached or detached, and the detection switch 55 may be damaged.

  The mounting portion 21 is provided with a pair of left and right power supply terminals 71 for supplying a charging current to the electric razor mounted at the charging position. As shown in FIGS. 4 and 5, the power supply terminal 71 is provided on each of the left and right wall surfaces 51 and 52 of the mounting portion 21 that sandwiches the main body 1. As shown in FIGS. 1 and 7, each power supply terminal 71 includes a terminal portion 72 that engages with the power receiving terminal 15 of the electric razor, a fixing portion 73 for fixing the power supply terminal 71 to the charger body 18, and one end thereof. The arm part 74 is connected to the terminal part 72 and the other end is connected to the fixing part 73 to support the terminal part 72 so as to be swingable and displaceable with respect to the fixing part 73, and the fixing part 73 on the other end side of the arm part 74. Are integrally provided with a lead connection portion 75 connected to the lead wire to which the lead wire is connected. The fixed portion 73, the arm portion 74, and the lead connecting portion 75 are formed in a plate shape, and the arm portion 74 is bent forward with respect to the fixed portion 73, and the lead connecting portion 75 is bent backward. Thereby, the fixing | fixed part 73, the arm part 74, and the lead connection part 75 are integrally bent in the crank shape.

  The terminal portion 72 of each power supply terminal 71 is supported by the arm portion 74 so as to be able to move in and out so as to face the terminal openings 76 opened on the left and right wall surfaces 51 and 52, and toward the advancing direction (electric razor side). It is urged by the urging member 77. The terminal portion 72 is guided and supported on the inner peripheral surface of the terminal opening 76 so as to be retractable. The urging member 77 includes a compression coil spring provided between the terminal portion 72 and the inner surface of the outer housing 24 facing the terminal portion 72.

  Since the plate-like arm portion 74 can be elastically deformed, the terminal portion 72 is also urged forward by the elasticity of the arm portion 74, and thus the arm portion 74 also functions as the urging member 77. According to such a power supply terminal 71, the arm portion 74 can be used as the biasing member 77, so that the compression coil spring 77 can be omitted. In this case, since it is not necessary to provide the compression coil spring 77, the structure around the power supply terminal 71 can be simplified, and the manufacturing cost of the charger can be reduced. Even when the compression coil spring 77 is provided, the spring rate of the compression coil spring 77 can be reduced, and the assembly of the power supply terminal 71 and the compression coil spring 77 can be improved.

The terminal portion 72 is formed with an annular peak portion 80 that protrudes toward the power receiving terminal 15 and a mortar-shaped valley portion 81 that is surrounded by the peak portion 80. The power receiving terminal 15 engages with the terminal portion 72 in a state where the hemispherical contact portion 16 gets over the mountain portion 80 and fits into the mortar-shaped valley portion 81. Thus, when the annular crest 80 and the mortar-shaped trough 81 surrounded by the crest 80 are formed in the terminal 72, the feeding terminal 71 moves in the engaging direction at the crest 80. The electric razor can be accurately held at an appropriate charging position. Further, when the power receiving terminal 15 crosses the peak portion 80 and falls into the valley portion 81, a feeling of moderation can be given, and the user can recognize that the electric razor is attached at an appropriate charging position. Further, regardless of the direction in which the power receiving terminal 15 is engaged or disengaged with respect to the terminal portion 72, the same moderation feeling can be obtained and the operation can be separated with the same operation force.
Further, when the contact portion 16 at the tip of the power receiving terminal 15 formed in a spherical shape is engaged in a state where the contact portion 16 is fitted in the mortar-shaped valley portion 81, the contact portion 16 and the valley portion 81 can be brought into line contact in a circular shape. Since it can do, both 15 * 81 can be made to contact exactly and the electrical resistance in a contact part can be reduced.

  As described above, when the annular (annular) peak portion 80 is formed in the terminal portion 72, the structural strength of the terminal portion 72 can be increased, so that the charging operation can be stably performed over a long period of time. In addition, the peak part 80 can also be formed in a triangular annular shape, a square annular shape, or a polygonal annular shape. In this case, when the power receiving terminal 15 is engaged with the terminal portion 72, the feeling of moderation changes between the case of getting over the side portion and the case of getting over the corner portion, and when the power receiving terminal 15 is separated from the terminal portion 72, The separation operation force changes depending on whether the vehicle crosses the corner or the corner.

  Each of the outer slope 82 and the inner slope 83 of the mountain portion 80 has a tapered surface, and the downward slope angle of the outer slope 82 with respect to the plane passing through the apex of the mountain portion 80 is the downward slope angle of the inner slope 83. Is set larger than. According to this, when the contact portion 16 gets over the outer slope 82 and engages with the valley portion 81, the resistance to the ride over becomes relatively large, so that a certain degree of moderation can be obtained, and the user can use an electric razor. It can be clearly recognized that it is mounted at the charging position. Further, when the contact portion 16 separates from the valley portion 81 over the inner slope 83, the resistance to overcome is relatively small, so that the separation operation force can be reduced, and the user can remove the electric razor with a light force. Can be removed. Note that the timing at which the contact portion 16 climbs over the peak portion 80 during engagement is during the mounting operation of the electric razor on the mounting portion 21, so even if the resistance is relatively large, it can be easily contacted with the momentum of the mounting operation. The portion 16 can be engaged with the valley portion 81.

  The terminal portion 72 is provided with a cylindrical portion 84 that is continuous with the skirt portion of the outer slope 82. The arm portion 74 is integrally connected to the bottom portion of the cylindrical portion 84. In addition, a restricting portion 85 is formed at the bottom of the cylindrical portion 84 on the side opposite to the arm portion 74, and the restricting portion 85 contacts the inner step portion of the terminal opening 76, whereby the terminal portion 72. The limit of advancement is defined. The power supply terminal 71 is formed by subjecting a blank material made of a metal plate punched into a predetermined shape to bending and drawing by a pressing device. As described above, when the cylindrical portion 84 that is continuous to the skirt portion of the outer slope 82 of the mountain portion 80 is provided, the structural strength of the terminal portion 72 can be further increased, and the charging operation can be performed stably over a longer period.

  The majority portion (one end side) of the compression coil spring 77 described above on the terminal portion 72 side is provided in a state of being accommodated in the cylindrical portion 84. Further, the end winding portion on the terminal portion 72 side of the compression coil spring 77 is received by the bottom surface of the annular recess-shaped receiving recess 86 formed on the inner surface side of the peak portion 80. As described above, when the terminal portion 72 is biased toward the electric razor in a state where one end of the compression coil spring 77 is accommodated in the cylinder portion 84, the movement of the compression coil spring 77 can be restricted by the cylinder portion 84. The repulsive force of the spring 77 can be accurately received and the terminal portion 72 can be reliably advanced and biased. There is also an advantage that the compression coil spring 77 can be stably supported. Further, when the end winding portion of the compression coil spring 77 accommodated in the cylindrical portion 84 is received by the annular recess-shaped receiving recess 86, the movement of the compression coil spring 77 can be more reliably restricted. Thus, the terminal portion 72 can be advanced and biased more reliably by receiving the repulsive force. There is also an advantage that the compression coil spring 77 can be supported more stably.

  The fixing portion 73 is fixed to a terminal fixing seat 89 formed on the back surface of the inner housing 25. Specifically, a through-hole 90 that penetrates the plate surface is formed in the fixing portion 73, and the terminal fixing seat 89 has a direction (rearward direction) orthogonal to the direction in which the terminal portion 72 is withdrawn (left-right direction). A fixing pin (fixing tool) 91 having an axial center is projected. The fixing portion 73 can be fixed to the terminal fixing seat 89 by inserting the fixing pin 91 into the through-hole 90 to bring the fixing portion 73 into close contact with the terminal fixing seat 89 and melting the tip of the fixing pin 91 in this state. Note that the fixture 91 may be configured with a screw or the like that is screwed into the terminal fixing seat 89 through the through hole 90 instead of the fixing pin.

As described above, when the axial center direction of the fixing pin 91 for fixing the fixing portion 73 to the inner housing 25 (charger main body 18) and the protruding and retracting direction of the terminal portion 72 are orthogonal to each other, the terminal portion Since the fixing portion 73 tends to move in the extending direction with the movement of 72, the shearing direction force acts on the fixing pin 91. As a result, the fixing portion 73 is firmly received by the fixing pin 91 and does not rattle, and the terminal portion 72 can accurately move out and out. On the contrary, when the axial direction of the fixed pin 91 and the extending / retracting direction of the terminal portion 72 are configured to be parallel, for example, when the fixed pin 91 is a screw, the terminal portion 72 is moved in and out. Since a force along the fastening direction acts on the screw, the screw may gradually loosen.

  The extending / retracting direction of the terminal portion 72 and the extending direction of the fixing portion 73 are the same direction (left-right direction), and both 72 and 73 are arranged at positions shifted forward and backward, and the axial direction of the fixing pin 91 (front-rear direction) Direction) is configured to be orthogonal to the direction in which the terminal portion 72 is withdrawn and the direction in which the fixing portion 73 extends. The extending direction of the arm portion 74 is formed so as to be inclined with respect to the axial direction of the fixing pin 91, and the internal angle θ sandwiched between the fixing portion 73 and the arm portion 74 integrally formed in a bent plate shape is an obtuse angle. It is set to be. According to this, compared with the case where the internal angle θ is set to be a right angle, the entire length of the arm portion 74 can be formed longer, and the elastic deformation amount of the arm portion 74 accompanying the movement of the terminal portion 72 can be reduced. Further, fatigue failure of the arm portion 74 due to repeated elastic deformation can be avoided. Further, even when the internal angle θ is set to an acute angle, the entire length of the arm portion 74 can be formed long. In this case, however, the boundary portion between the fixed portion 73 and the arm portion 74 (a sharp bend). However, it is disadvantageous in that it tends to cause fatigue failure.

In the present embodiment, the total force of the urging force (compression coil spring 77 and arm portion 74) that urges each power supply terminal 71 to advance is a urging member (movable spring) that urges the detection switch 55 to advance. It is set to be larger than the urging force of 58. Thus, when the urging force of each urging member 58 and 77 is set, it is possible to prevent the electric razor from floating from the wall surface by sandwiching the electric razor with a larger urging force.
Further, as described above, the electric razor attached to the proper charging position of the attachment portion 21 is leaning against the rear wall surface 50. Therefore, in the halfway mounting position where the entire electric razor is vertically inverted (not tilted backward), even if the power receiving terminal 15 and the power feeding terminal 71 are in contact, the detection switch 55 Is not switched on, so no charging current is supplied.

  In the electric razor charger of this embodiment, the power supply terminals 71 are provided on the left and right wall surfaces 51 and 52 of the mounting portion 21 facing each other with the electric razor in between, and the detection switch 55 is provided on the remaining rear wall surface 50. According to such an arrangement form of the power feeding terminal 71 and the detection switch 55, the position of the pair of power feeding terminals 71 is held by holding the electric razor via the power receiving terminal 15 with the biasing force acting in the opposite direction by the biasing member 77 of the pair of power feeding terminals 71. In addition, it is possible to effectively prevent the electric razor from floating from the wall surface by the urging force of the urging member 58 of the detection switch 55 and the external force acting on the charger.

  When the razor head 2 that has been washed with water is attached to the attachment portion 21, the remaining water after washing drops and accumulates in the bottom housing 26. In order to drain the water, as shown in FIG. 4 and FIG. 8, a drain port 94 is opened in the bottom housing 26, and the water drained from the drain port 94 is received and stored below the drain port 94. A drain tray 95 is provided. Between the drain port 94 and the drain tray 95, a drain cylinder 96 is provided for guiding the water to flow down to the drain tray 95. The drainage tray 95 is detachably mounted on a tray mounting portion 98 having a tray opening 97 that opens on the right peripheral side surface of the charger body 18, and is detachable in the left-right direction (horizontal direction) through the tray opening 97. It is attached to. Thereby, the attachment / detachment direction of the drainage tray 95 is set in a direction (horizontal direction) parallel to the mounting surface of the charger, and is orthogonal to the flow-down direction of the water flowing through the drainage port 94. The tray mounting portion 98 is recessed upward on the bottom surface of the base frame 19, and a part of the tray mounting portion 98 is exposed at the lower portion of the right side surface of the charger body 18, and the exposed portion is a tray opening 97. The upper portion and the front and rear portions of the tray opening 97 connected to the right side surface of the charger main body 18 are provided with oblique notches so that the drainage tray 95 can be easily grasped with a fingertip.

  The drain tray 95 is formed in a square container shape whose upper surface is opened by a circumferential peripheral wall 101 and a bottom wall 102, and the left and right corners on the left and right sides are rounded. A flange wall 103 is extended outwardly from the upper edge of the front and rear side and left peripheral wall 101. A dust receiving recess 104 is formed in a part of the bottom wall 102 of the drain tray 95, and the dust receiving recess 104 is provided at a position facing the drain port 94. In addition, the dust receiving recess 104 is formed in the bottom wall 102 so as not to contact the peripheral side wall 101. The curvature of the corner 105 sandwiched between the inner peripheral surface and the bottom surface of the dust receiving recess 104 is set to be smaller than the curvature of the corner 106 sandwiched between the inner surfaces of the peripheral side wall 101 and the bottom wall 102. Since the curvature of the corner 105 of the present embodiment is made as small as possible, the corner 105 is formed in a substantially inclined plane connecting the bottom surface of the bottom wall 102 and the bottom surface of the dust receiving recess 104. The front and rear peripheral side walls 101 facing the tray opening 97 are formed with a finger-hanging concave portion 107 so that the drainage tray 95 can be more easily gripped by the fingertip (see FIGS. 4 and 10).

As described above, the attaching / detaching direction of the drainage tray 95 attached / detached from the tray attaching portion 98 through the tray opening 97 formed on the right peripheral side surface of the charger main body 18 is set in a direction parallel to the placement surface of the charger. Then, the drain tray 95 can be attached and detached without lifting the charger, and the water stored in the drain tray 95 can be easily disposed. There is also an advantage that the drainage tray 95 can be attached / detached smoothly as compared with the case where the drainage tray 95 is attached / detached while being pulled up obliquely upward or downwardly with respect to the mounting surface.
Further, when the dust receiving recess 104 is formed in the bottom wall 102 of the drain tray 95 facing the drain port 94, if the dust is mixed in the discharged water, the dust receiving reservoir 104 can collect the shavings. It is possible to suppress as much as possible the spilling of water containing hair dust from the drain tray 95 and to prevent the mounting surface around the charger from being soiled by the hair dust.
Further, the curvature of the corner portion 105 sandwiched between the inner peripheral surface and the bottom surface of the dust receiving recess 104 is smaller than the curvature of the corner portion 106 sandwiched between the inner surfaces of the peripheral side wall 101 and the bottom wall 102 of the drain tray 95. When set, the corner 105 of the dust receiving recess 104 is made larger while the capacity of the drain tray 95 is increased as much as possible by the corner 106 between the peripheral side wall 101 and the bottom wall 102 of the drain tray 95 where the dust does not collect easily. Since it can be made into the shape which it is hard to collect hair dust and is easy to clean, the cleaning of the drain tray 95 can be facilitated.

  As described above, the electric razor in the mounting position moves backward and in the left and right directions at the upper ends of the three rear wall surfaces 50, the left wall surface 51, and the right wall surface 52 on the inner peripheral surface surrounding the mounting portion 21. In the plan view of the charger, the drain tray 95 is drawn out and separated in the right direction (on the opposite side to the movement regulating direction of the electric razor). According to this, even when the electric razor is grasped and the drainage tray 95 is separated, the movement of the electric razor is regulated and the proper charging position can be maintained. Therefore, even when the drainage tray 95 is separated during charging of the electric razor. The charging operation of the electric razor is surely continued.

  As shown in FIGS. 8 and 10, a rail wall (support wall) 110 projects inwardly on each of the inner wall surfaces before and after the tray mounting portion 98. The drain tray 95 is mounted on the tray mounting portion 98 in a state where the rail wall 110 receives the flange wall 103 (the lower surface of the drain tray 95) of the drain tray 95. The rail wall 110 also serves as a guide member that slides and guides the drain tray 95 that is inserted from the tray opening 97. The charger body 18 is provided with a pressing body 111 that presses and biases the drain tray 95 against the rail wall 110.

  As shown in FIG. 9, the pressing body 111 includes a fixing portion 112 that is fixed to the base frame 19 (charger body 18), a pressing portion 113 that contacts the drain tray 95, a fixing portion 112, and the pressing portion 113. A pair of elastic arms 114 that can be elastically deformed and connected together are provided. The pressing part 113 is formed in a band plate shape that curves downward and is provided so as to connect the ends of the pair of elastic arms 114. The fixed portion 112 is formed in a frame shape (endless annular shape) having a circular flow path opening 115 at the center of the plate surface. One set of the pressing portion 113 and the pair of elastic arms 114 are provided before and after the fixing portion 112. The pressing body 111 is formed by bending a blank material made of a metal plate punched into a predetermined shape by a press device.

  As described above, when the charger body 18 is provided with the pressing body 111 that presses and biases the flange wall 103 of the drainage tray 95 on the rail wall 110 of the tray mounting portion 98, the drainage tray 95 is vertically moved by the pressing body 111. Since it is possible to prevent rattling, it is possible to prevent the stored water from spilling due to the drainage tray 95 rattling unnecessarily during the drawer operation. Further, the frictional resistance at the contact surface between the flange wall 103 of the drain tray 95 and the upper surface of the rail wall 110 provides an appropriate operational feeling when the drain tray 95 is attached and detached, and the drain tray 95 is quickly pulled out and separated. Therefore, it is possible to prevent the drainage tray 95 from being spilled or the drainage tray 95 from being damaged by being quickly inserted and attached.

  On the outer peripheral surface of the drain cylinder 96 described above, a circular fixed seat 116 is formed, and the drain cylinder 96 is formed in a stepped cylinder. By fixing the fixing portion 112 to the fixed seat 116, The pressing body 111 is fixed to the charger main body 18. The fixing portion 112 is fixed to the base frame 19 with the drainage port 94 of the bottom wall 49 facing the flow path opening 115 of the fixing portion 112. Specifically, through holes 117 are formed at the four corners of the fixing portion 112, and fixing pins 118 are projected upward at positions corresponding to the through holes 117 on the fixing seat 116. The upper half of the drain tube 96 is inserted into the flow path opening 115 of the fixed portion 112, and the fixed portion 112 is externally fitted to the drain tube 96. Furthermore, the fixing portion 112 can be fixed to the fixing seat 116 by bringing the fixing portion 112 into close contact with the fixing seat 116 and melting the tip of the fixing pin 118 in this state. Note that the pressing body 111 can be fixed with a screw or the like that is screwed into the fixing seat 116 through the through hole 117 instead of the fixing pin 118.

The fixing portion 112 of the pressing body 111 can be stably fixed as the outer shape thereof is formed larger, and the elastic arm 114 can be elastically deformed more flexibly. However, the space for fixing the fixing portion 112 is increased accordingly. This requires a large charger. However, when the fixing portion 112 is fixed to the base frame 19 with the drainage port 94 of the bottom wall 49 facing the channel opening 115 of the fixing portion 112 formed in an endless annular shape as in the present embodiment, the fixing portion 112 While the outer shape is enlarged, it can be used as a flow path through which the drainage passes through the central portion of the fixed portion 112 that becomes a dead space. Accordingly, the entire charger can be made compact while allowing the elastic arm 114 to be elastically deformed flexibly.

  The tip of each pressing portion 113 protrudes into the tray mounting portion 98 through an exposure hole 119 provided in the base frame 19, and the protruding portion of the pressing portion 113 is engaged with the drain tray 95. The recess 120 is engaged. The engaging recess 120 is formed by a recess formed on the upper surfaces of the peripheral side wall 101 and the flange wall 103. When the drain tray 95 is mounted on the tray mounting portion 98, the pressing portion 113 is formed on the engaging recess 120. Engaging in drop. In this manner, when the engaging recess 120 is formed on the upper surface of the drainage tray 95 so that the pressing portion 113 falls and engages when the tray 95 is in the mounting position, the drainage tray 95 can be held in the mounting position. it can. In addition, when the drainage tray 95 is attached or detached, when the pressing portion 113 comes out of the engaging recess 120 at the start of pull-out separation and when the pressing portion 113 falls into the engaging recess 120 at the end of the insertion, the user In order to feel the feeling of operation, the pressing body 111 and the engaging recess 120 can function as a moderation structure. Since the functions of both the position holding structure and the moderation structure of the drain tray 95 can be combined, there is an advantage that the manufacturing cost can be reduced by reducing the number of parts.

Two elastic arms 114 are extended from the fixing portion 112, and the tips of the elastic arms 114 are respectively connected to the end portions of the pressing portions 113 formed in a band plate shape that curves downward toward the drain tray 95. Therefore, the fixing part 112, the elastic arm 114, and the pressing part 113 are formed in a frame shape. Thereby, the structural strength of the pressing body 111 can be increased, and the elastic arm 114 can be elastically deformed more smoothly, so that an accurate position holding function and a clear moderation function can be exhibited. Since the fixing portion 112 is provided with a pair of elastic arms 114 and a pressing portion 113 so as to face each other with the fixing portion 112 in between, a drain tray 95 is provided at two locations.
Can be pushed down toward the rail wall 110, and the drain tray 95 can be more reliably prevented from rattling in the vertical direction. It is also advantageous in that a more accurate position holding function and a clear moderation function can be exhibited.

When a drain tube 96 that guides the water drained from the drain port 94 to the drain tray 95 is provided on the base frame 19, and the fixing portion 112 of the pressing body 111 is fixed to the drain tube 96, the structure frame of the charger is used. Since the fixing portion 112 can be supported and fixed by a certain charger main body 18, the pressing body 111 can be firmly fixed, and a more accurate position holding function and a clear moderation function can be exhibited.
Further, when the fixing portion 112 of the pressing body 111 is fixed to the fixing seat 116 of the drainage cylinder 96 in a state in which the flow path opening 115 of the pressing body 111 is fitted around the drainage cylinder 96, the fixing portion 112 becomes the cylinder of the drainage cylinder 96. Since the movement in the direction orthogonal to the axis is regulated and supported, the pressing body 111 can be more firmly fixed.

  The charger main body 18 is provided with a power socket 123 for receiving power supplied by the charger. A connection plug 124 provided at one end of the power cord is plugged into the power socket 123 and connected thereto. Yes. The power cord on the other end side of the connection plug 124 is provided with a plug that is plugged into a commercial power outlet. As shown in FIG. 10, when a virtual line V extending in the front-rear direction passing through the center of the charger main body 18 is assumed in the plan view of the charger, the right side (one side) of the charger main body 18 divided by the virtual line V The tray opening 97 is arranged in the area of the power supply, and the power socket 123 is arranged in the left (the other) area.

  If the tray opening 97 is disposed in the right region of the charger body 18 divided by the virtual line V as described above and the power socket 123 is disposed in the left region, the distance between the tray opening 97 and the power socket 123 can be increased. Even if water is spilled when the drain tray 95 is separated, the power socket 123 does not get water. Therefore, it is possible to effectively prevent a short circuit and corrosion from occurring in the power socket 123. When assuming the previous virtual line V and the second virtual line passing through the center of the charger main body 18 and orthogonal to the virtual line V, the tray opening 97 and the power socket 123 are arranged in the quadrant area in the diagonal position. You can also In this case, both 97 and 123 can be further distant from each other, and water can be further prevented from adhering to the power socket 123 when the drain tray 95 is attached or detached.

  The connection plug 124 is inserted and connected to the power socket 123 from the rear to the front. Thereby, the attachment / detachment direction of the drain tray 95 and the insertion direction (front-rear direction) of the connection plug 124 are configured to be orthogonal to each other. Further, the insertion direction of the connection plug 124 is set in a direction (horizontal direction) parallel to the mounting surface of the charger. As described above, the attachment / detachment direction of the drain tray 95 is orthogonal to the flow direction of the water flowing through the drain port 94, so the attachment / detachment direction of the drain tray 95, the insertion direction of the connection plug 124, and the drain port 94 The flow direction is configured to be orthogonal to each other.

As described above, when the attachment / detachment direction of the drain tray 95 and the insertion direction of the connection plug 124 inserted and connected to the power socket 123 are orthogonal to each other, an attempt is made to separate the drain tray 95 while holding the power cord. Even in this case, it is possible to prevent the connection plug 124 from coming off as much as possible. Therefore, even when the drainage tray 95 becomes full and the drainage tray 95 must be separated during charging of the electric razor, the charging operation of the electric razor can be prevented from being interrupted. For example, when the direction in which the drain tray 95 is attached and detached is opposite to the direction in which the connection plug 124 is inserted, if the drain tray 95 is separated while holding the power cord, the connection plug 124 may also come off.
Further, when the insertion direction of the connection plug 124 is set in a direction parallel to the mounting surface of the charger, as in the case of the drainage tray 95, while pulling up obliquely upward or downwardly downward with respect to the mounting surface. As compared with the case where the drain tray 95 is attached / detached, the connection plug 124 can be attached / detached smoothly.

  The power socket 123 is provided in an inner part of a socket recess 125 formed in the charger body 18. The socket recess 125 is recessed upward on the bottom surface of the base frame 19 and opens at the left, rear, and bottom surfaces of the charger body 18. As shown in FIGS. 10 and 11, the inner wall surfaces constituting the upper and right sides of the socket recess 125 are formed in a tapered shape toward the inner depth in the insertion direction of the connection plug 124. According to such a socket recess 125, the inlet side of the socket recess 125 can be widened and the inner back portion can be narrowed. Thus, at the initial connection of the connection plug 124 to the power socket 123, the connection plug 124 can be easily inserted into the socket recess 125, and interference between the connection plug 124 and the outer surface of the charger main body 18 can be prevented. Further, in the middle connection period of the connection plug 124, the connection plug 124 is guided by the wall surface, and the connection plug 124 can be inserted so as to approach the socket recess 125, thereby facilitating the connection of the connection plug 124 to the power socket 123. it can. In this embodiment, both the inner wall surfaces constituting the upper side and the right side are tapered toward the inner depth in the insertion direction of the connection plug 124, but only one of the inner wall surfaces is tapered. You may form in the shape of a circle.

  A heating means that is driven together with the air blowing means in the drying operation is provided in the mounting portion 21. As shown in FIGS. 3, 5, and 12, the heating means includes a bottom wall 49 (bottom housing 26) of the mounting portion 21, a heater 128 provided on the bottom surface of the bottom wall 49, a bottom wall 49 and a heater 128. And a protective plate 129 made of metal provided between the two. The heater 128 is a sheathed heater having a circular cross section, and is provided in an annular shape around a square frame-like heater base 130 which is fixed to the partition wall 28 of the base frame 19 and which is long on the left and right. The inner opening portion of the heater base 130 is disposed so as to face the light-transmitting window 44 described above, whereby the heater 128 is disposed on the lower surface periphery of the light-transmitting window 44. The protection plate 129 is formed in a square frame shape surrounding the light transmission window 44, and the lower surface thereof is in close contact with the heater 128, and the upper surface is in close contact with the back surface of the bottom wall 49.

  In the electric razor at the charging position, the tip of the razor head 2 is in contact with the bottom wall 49, and the razor head 2 is heated by driving the heating means and the air blowing means, and the drying air is fed and washed with water. The drying of the razor head 2 is promoted. However, the main blade 4 and the trimmer unit 5 provided in the cutting blade portion 3 have a dense structure, and the inner blade 6 and the outer blade 7, and the movable blade 8 and the fixed blade 9 are provided in close contact with each other. Therefore, it is inevitable that drying takes time. Therefore, in the present embodiment, a raised wall 133 is provided on the bottom wall 49 so as to face the front of the cutting blade portion 3. As shown in FIG. 12, the raised wall 133 rises upward in a cross-sectional crank shape, and the upper end portion thereof is in direct contact with the front surface of the trimmer unit 5. In addition, the raised wall 133 can be provided so as to face the back surface of the cutting blade portion 3, and the two raised walls 133 can be provided so as to face the front surface and the back surface of the cutting blade portion 3. Further, a raised wall 133 that faces the left and right side surfaces of the tip of the razor head 2 can be provided.

  As shown in FIGS. 12 and 13, the heating means includes a heat transfer plate 134 for conducting heat to the raised wall 133. The heat transfer plate 134 is formed by bending a metal plate, and is connected to the conductive plate 135 extending upward along the raised wall 133 and the lower end of the conductive plate 135 to receive heat from the heater 128. Plate 136. The conductive plate 135 is formed in a crank shape along the back surface of the raised wall 133 and is in close contact with the back surface of the raised wall 133. An insertion groove 140 is provided on the raised wall 133 and on the back surfaces of the left and right peripheral edges, and the upper edge portion and the left and right edge portions (side edges extending vertically) of the heat transfer plate 135 are provided in the insertion groove 140. Each is plugged. The heat receiving plate 136 is in close contact with the upper surface of the front side of the protection plate 129, and the heat of the heater 128 is conducted to the heat transfer plate 134 through the protection plate 129. The conductive plate 135 can also be provided in a state of facing the back surface of the raised wall 133 with a slight gap.

As described above, when the conductive plate 135 is provided in close contact with the back surface of the raised wall 133, the shape of the raised wall 133 formed of a flexible material can be held by the conductive plate 135, and the raised wall 133 is cut into a cutting blade. It is possible to accurately face the front of the part 3. Further, the heat of the conductive plate 135 can be efficiently moved to the raised wall 133. Therefore, the cutting blade part 3 can be effectively heated to further accelerate the drying of the razor head 2 after washing with water.
Further, when the upper edge portion of the conductive plate 135 and the edge portion extending vertically are inserted into the insertion grooves 140 provided on the back surface of the raised wall 133, the raised wall 133 and the conductive plate 135 are integrally formed. As a result, the shape of the raised wall 133 can be maintained more accurately. There is also an advantage that the heat transfer loss between the both 133 and 135 due to the separation of the raised wall 133 and the conductive plate 135 can be reduced.
Further, when the raised wall 133 is raised upward in a cross-sectional crank shape and the conductive plate 135 is formed in a shape along the rear surface of the raised wall 133, the razor head 2 is raised by the raised wall 133 when the electric razor is inserted into the mounting portion 21. Even when in contact with the conductive plate 135, the crank-shaped cross section exhibits springiness, so that the conductive plate 135 can be prevented from buckling. When the raised wall 133 has a straight cross section, the conductive plate 135 may come out of the insertion groove 140 if the raised wall 133 is stretched and deformed so as to extend upward. However, in this embodiment, since the bent portion is formed in the middle of the conductive plate 135, only the raised wall 133 above the bent portion is stretched and deformed. It is possible to suppress detachment from the groove 140.

  The heat transfer plate 134 is fixed to a plate fixing seat 141 formed on the partition wall 28 of the base frame 19.

Further, the tip of the razor head 2 is heated by the bottom wall 49 heated by the heater 128, and the front surface of the cutting blade 3 is actively heated by the raised wall 133, so that the razor head 2 after washing with water can be effectively washed. Drying can be promoted.
Further, when the metal protective plate 129 is provided between the bottom wall 49 and the heater 128, the heater 128 can be protected by the protective plate 129 even when an electric razor falls on the bottom wall 49. In addition, when the heat receiving plate 136 of the heat transfer plate 134 is brought into close contact with the plate surface of the protective plate 129, the heat of the heater 128 can be received by the heat receiving plate 136 via the metal protective plate 129. As a result, it is possible to substantially eliminate a decrease in heat conduction efficiency from the heater 128 to the heat transfer plate 134.
In this embodiment, a sheathed heater having a circular cross section is used as the heater 128. Therefore, when the heater 128 is brought into close contact with the bottom wall 49, both 49 and 128 come into line contact. However, by interposing a metal protective plate 129 between the two 49 and 128, the heat of the heater 128 can be conducted to the wider bottom wall 49 via the protective plate 129. It can be heated efficiently.

In the above embodiment, the plug 124 on one end of the power cord is connected to the power socket 123, and the plug on the other end of the power cord is connected to a commercial power outlet, and then an electric shaver in an inverted position is attached.

Further, when the switch element 32 is pushed, the operation mode can be switched between the charging mode and the dry sterilization mode. In this case, the detection switch 55 functions as a switch for switching the charger to a standby state in which the charging, drying, and sterilization operations can be performed. In this mode of operation, the standby mode, the charging mode, and the dry sterilization mode are configured to be switched in a loop each time the switch element 32 is pushed.

  According to the electric razor charger having the above-described operation mode, when an electric razor with sufficient charge remaining in the secondary battery 13 is attached to the attachment portion 21 for storage, an unnecessary charging operation is performed. Therefore, the deterioration of the secondary battery 13 due to frequent repeated short-time charging operations can be suppressed. When the remaining charge of the secondary battery 13 is lower than 40%, for example, the charging operation may be started without the push operation of the switch element 32.
