In the charger of the small electric device of the present invention, the power supply terminal 71 and the detection switch 55 are used.
Of the inner peripheral surfaces surrounding the mounting portion 21, the front and rear peripheral surfaces and the left and right peripheral surfaces are arranged on a plurality of peripheral surfaces, and the biasing members 77 and 58 advance toward different peripheral surfaces of the small electric device in the mounted state. I tried to do it. According to this, since the urging force by the urging members 77 and 58 can be applied to the peripheral surface of the small electric device from a plurality of directions, the small electric device mounted on the mounting portion 21 carelessly touches the wall surface. It is possible to prevent the battery from moving away from the charging position. From the above, according to the present invention, the small electric device can be held in an appropriate charging position and the charging operation can be stably executed. In addition, it is not necessary to provide a dedicated holding structure, and it is possible to suppress an increase in the manufacturing cost of the charger.

At least 3 of the front and rear peripheral surfaces and the left and right peripheral surfaces of the peripheral surface of the small electric device in the mounted state
The peripheral surface faces the three wall surfaces 50, 51, and 52 of the inner peripheral surface surrounding the mounting portion 21, and the power supply terminals 71 are connected to the facing wall surfaces 51 and 52 of the mounting portion 21 with a small electric device in between. And a detection switch 55 is provided on the remaining wall surface 50. When the power feeding terminal 71 and the detection switch 55 are arranged in this way, the small electric device can be moved through the power receiving terminal 15 by the urging force acting in the opposite direction by the urging member 77 of the pair of power feeding terminals 71. It is sandwiched and held in position, and the urging force of the urging member 58 of the detection switch 55 and the external force acting on the charger can surely prevent the small electric device from floating away from the wall surface.

The detection switch 55 is provided with a contact body 56, a switch body 57, an urging member 58, and the like.
When the contact portion of the contact body 56 that comes into contact with the small electric device is composed of a plurality of ribs 68 extending in the insertion direction of the small electric device, the contact area between the small electric device and the contact portion can be made possible. It can be made smaller in size, and damage due to friction between the small electric device and the contact portion at the time of attachment / detachment can be suppressed. Further, for example, even when a small electric device washed with water is mounted on the mounting portion 21, water adhering to the contact body 56 can flow downward through between the adjacent ribs 68 and 68, so that the detection switch 55 can be used. It is possible to prevent the detection switch 55 from malfunctioning due to the accumulation of water around it and improve the safety of the charger. If the plurality of ribs 68 are formed so as to cross the insertion direction of the small electric device, the small electric device may be caught by the rib 68 when the small electric device is attached or detached, and the detection switch 55 may be damaged.

If the total force of the urging force of the urging member 77 advancing each power supply terminal 71 is set to be larger than the urging force of the urging member 58 advancing the detection switch 55, the urging force becomes larger. By sandwiching the small electric device, it is possible to more effectively prevent the small electric device from floating off the wall surface.

The terminal portion 72 of the power supply terminal 71 is provided with two peaks 80/80 intersecting the insertion mounting direction of the small electric device and a valley 81 formed between the two peaks 80/80 to receive power. 15 can be configured to overcome one peak 80 and engage the valley 81. According to this, since it is possible to regulate the movement of the power feeding terminal 71 in the engaging direction at both mountain portions 80 and 80, it is possible to accurately hold the small electric device in an appropriate charging position. Further, when the power receiving terminal 15 gets over the mountain portion 80 and falls into the valley portion 81, a sense of moderation can be imparted.
It is possible to make sure that the user recognizes that the small electric device is installed in the proper charging position.

When the terminal portion 72 is formed with the annular peak portion 80 and the valley portion 81 surrounded by the peak portion 80, the movement of the power receiving terminal 15 is restricted not only in the engagement direction but also in the entire circumferential direction. It is possible to accurately hold the position of a small electric device by an appropriate charging position. Further, when the annular mountain portion 80 is formed on the terminal portion 72, the structural strength of the terminal portion 72 can be increased, so that the charging operation can be stably executed for a long period of time, which can contribute to the improvement of the reliability of the charger. ..

When the mountain portion 80 is formed in a triangular ring shape, a square ring shape, or a polygonal ring shape, for example, when the power receiving terminal 15 engages with the terminal portion 72, the case where the power receiving terminal 15 gets over the side portion and the case where the mountain portion 80 gets over the corner portion. The sense of moderation changes. Further, when the power receiving terminal 15 is separated from the terminal portion 72, the separation operation force changes depending on whether the power receiving terminal 15 gets over the side portion or the corner portion. On the other hand, as in the present invention, the terminal portion 72 has an annular mountain portion 80 and a mortar-shaped valley portion 81 surrounded by the mountain portion 80.
When and is formed, the same sense of moderation can be obtained regardless of the engagement / disengagement direction of the power receiving terminal 15 with respect to the terminal portion 72, and the terminal portion 72 and the power receiving terminal 15 can be operated with the same operating force. And can be separated.

When the contact portion 16 at the tip of the spherically formed power receiving terminal 15 is engaged in a state of being fitted into the mortar-shaped valley portion 81, the contact portion 16 and the valley portion 81 can be linearly contacted in a circular shape. .. Therefore, it is possible to accurately bring the two 15 and 81 into contact with each other to reduce the electrical resistance at the contact portion.

Each of the outer slope 82 and the inner slope 83 of the mountain portion 80 is composed of a tapered surface, and the mountain portion 8
The downward inclination angle of the outer slope 82 can be set larger than the downward inclination angle of the inner slope 83 with respect to the plane passing through the apex of 0. According to this, when the contact portion 16 gets over the outer slope 82 and engages with the valley portion 81, the overcoming resistance becomes relatively large, so that a certain sense of moderation can be given to the user, and the user can give a certain sense of moderation. It is possible to clearly recognize that the small electric device is installed in the proper charging position. Further, when the contact portion 16 is separated from the valley portion 81 by overcoming the inner slope 83, the overcoming resistance is relatively small, so that the separation operation force can be reduced, and the user can use a small electric device with a light force. Can be removed. Since the timing at which the contact portion 16 gets over the mountain portion 80 at the time of engagement is during the mounting operation of the small electric device with respect to the mounting portion 21, even if a relatively large overcoming resistance occurs, the momentum of the mounting operation is sufficient. The contact portion 16 can be easily engaged with the valley portion 81.

If the terminal portion 72 is provided with a tubular portion 84 that is continuous with the hem portion of the outer slope 82 of the mountain portion 80, the structural strength of the terminal portion 72 can be further enhanced, and the charging operation can be stably executed for a longer period of time. ..

When one end of the compression coil spring 77, which is an urging member of the power feeding terminal 71, is housed in the tubular portion 84 and the terminal portion 72 is advanced and urged toward the small electric device, the compression coil spring 77 is accommodated in the tubular portion 84.
Since the movement of the compression coil spring 77 can be regulated, the repulsive force of the compression coil spring 77 can be accurately received and the terminal portion 72 can be reliably advanced and urged. Further, there is an advantage that the compression coil spring 77 can be stably supported.

When the end turn portion of the compression coil spring 77 housed in the tubular portion 84 is received by the annular valley-shaped receiving recess 86 formed on the inner surface side of the mountain portion 80, the movement of the compression coil spring 77 is more reliably performed. Since it can be regulated, the repulsive force of the compression coil spring 77 can be more accurately received, and the terminal portion 72 can be reliably advanced and urged. There is also an advantage that the compression coil spring 77 can be supported more stably.

The power supply terminal 71 is an arm portion 7 that connects the terminal portion 72, the fixed portion 73, and both 72 and 73.
4 can be integrally provided, the arm portion 74 can be formed so as to be elastically deformable, and the terminal portion 72 can be configured to swingably support in the retracting direction. According to such a power feeding terminal 71, since the arm portion 74 can be used as an urging member 77, it is not necessary to separately provide a member for generating an urging force, the structure around the power feeding terminal 71 is simplified, and the manufacturing cost of the charger is reduced. Can be reduced. Further, even when an urging member 77 such as a compression coil spring is separately provided, the spring rate of the urging member 77 can be reduced, and the assembling property of the power feeding terminal 71 and the urging member 77 can be improved.

If the axial direction of the fixing tool 91 for fixing the fixing portion 73 to the charger main body 18 and the moving / retracting direction of the terminal portion 72 are orthogonal to each other, the terminal portion 72 moves as the terminal portion 72 moves in and out. Fixed part 7
Since 3 tends to move in the extending direction, a force in the shearing direction acts on the fixture 91. As a result, the fixing portion 73 is not firmly received by the fixing tool 91 and rattles, and the terminal portion 72 can be accurately moved back and forth. When the axial direction of the fixture 91 and the exit / exit direction of the terminal portion 72 are parallel to each other, for example, if the fixture 91 is a screw, the terminal portion 72 moves with the exit / exit movement. Since a force acts on the screw along the fastening direction, the screw gradually loosens.

When the internal angle θ sandwiched between the fixed portion 73 and the arm portion 74 integrally formed in the shape of a bent plate is set to an obtuse angle, the total length of the arm portion 74 is formed longer than when the internal angle θ is set to a right angle. The amount of elastic deformation of the arm portion 74 due to the moving of the terminal portion 72 to and from the terminal portion 72 can be reduced. Therefore, it is possible to prevent the arm portion 74 from being fatigue-fractured due to repeated elastic deformation.
Even when the internal angle θ is set to an acute angle, the total length of the arm portion 74 can be formed to be long, but in this case, the boundary portion between the fixed portion 73 and the arm portion 74 (an acute-angled bent portion). Fatigue fracture is likely to occur.

A drainage port 94 is provided on the bottom wall 49 of the mounting portion 21, a drainage tray 95 for receiving water flowing down from the drainage port 94 is provided on the charger main body 18, and a tray opening 97 is provided on the peripheral side surface of the charger main body 18. The attachment / detachment direction of the drainage tray 95 that is detachably attached to the tray attachment portion 98 can be set in a direction parallel to the mounting surface of the charger. According to such a drain tray 95,
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 of. Further, there is an advantage that the drainage tray 95 can be smoothly attached / detached as compared with the case where the drainage tray 95 is attached / detached while being pulled up diagonally upward or diagonally downward with respect to the mounting surface.

The attachment / detachment direction of the drain tray 95 and the connection plug 12 inserted and connected to the power socket 123.
If the drainage tray 95 is configured to be orthogonal to the insertion direction of 4, even if the drainage tray 95 is to be separated while holding the power cord, it is effective that the connection plug 124 is inconvenient to come off. Can be prevented. Therefore, even when the drainage tray 95 is full and the drainage tray 95 needs to be separated during charging of the small electric device, it is possible to prevent the charging operation of the small electric device from being interrupted. For example, when the attachment / detachment direction of the drainage tray 95 and the insertion direction of the connection plug 124 are opposite to each other, the drainage tray 9 is held while holding the power cord.
If the 5 is tried to be separated, the connection plug 124 may come off and the charging operation may be stopped.

When the insertion direction of the connection plug 124 is set to be parallel to the mounting surface of the charger, the connection plug 124 is pulled up diagonally upward or diagonally downward with respect to the mounting surface, as in the case of the drain tray 95 above. However, as compared with the case where the drain tray 95 is attached / detached, the connection plug 124 can be attached / detached more smoothly.

Assuming a virtual line V passing through the center of the charger body 18 in the plan view of the charger, the tray opening 97 is arranged in one area of the charger body 18 divided by the virtual line V, and the tray opening 97 is arranged in the other area. A form in which the power socket 123 is arranged can be adopted. According to this, the tray opening 97
Since the distance between the power socket 123 and the power socket 123 can be increased as much as possible, it is possible to prevent the power socket 123 from being splashed with water even if water spills when the drain tray 95 is separated. Therefore, it is possible to prevent problems such as short circuit and corrosion from occurring in the power socket 123.

The power socket 123 is provided in the inner inner part of the socket recess 125 formed in the charger main body 18, and the inner peripheral wall of the socket recess 125 is formed in a constricted shape toward the inner inner part in the insertion direction of the connection plug 124. It can take the form of being. According to this, the socket recess 125
Since the inlet side of the socket can be widened and the inner part can be narrowed, it is easy to insert the connection plug 124 into the socket recess 125 at the initial stage of connection of the connection plug 124 to the power socket 123, and the connection plug 124. Can prevent interference with the outer surface of the charger body 18. Further, in the middle stage of connection of the connection plug 124, the connection plug 124 is guided by the wall surface and can be inserted so that the connection plug 124 approaches the socket recess 125, making it easy to connect the connection plug 124 to the power socket 123. Can be converted.

The small electric device mounted on the mounting portion 21 has three wall surfaces 50 on the inner peripheral surface surrounding the mounting portion 21.
It is assumed that the movement is restricted by 51 and 52, and the drain tray 95 can be configured to be pulled out and separated in the direction opposite to the movement regulation direction of the small electric device in the plan view of the charger.
According to this, even when the small electric device is grasped and the drain tray 95 is separated, the movement of the small electric device is restricted and the proper charging position is maintained. Therefore, the drain tray 95 is used while charging the small electric device. Even when separated, the charging operation of the small electric device can be surely continued.

The drainage tray 95 is formed in a container shape in which the upper surface is opened by the circumferential side wall 101 and the bottom wall 102, and the dust receiving recess 104 is recessed in the bottom wall 102 of the drainage tray 95 facing the drainage port 94. Can be done. According to such a drainage tray 95, even if hair dust is mixed in the discharged water, the hair dust can be collected in the dust receiving recess 104, so that the water containing the hair dust spills from the drainage tray 95. It is possible to prevent the mounting surface around the charger from being soiled by hair dust.

The dust receiving recess 104 does not come into contact with the peripheral side wall 101 of the drainage tray 95, and the tray 95 is not in contact with the peripheral side wall 101.
In addition to forming a recess in the bottom wall 102 of the drainage tray 95, the curvature of the entrance corner 105 sandwiched between the inner peripheral surface and the bottom surface of the dust receiving recess 104 is sandwiched between the peripheral side wall 101 of the drainage tray 95 and the inner surface of the bottom wall 102. It can be set smaller than the curvature of the corner 106. According to this, while increasing the capacity of the drainage tray 95 as much as possible at the entrance corner 106 between the peripheral side wall 101 and the bottom wall 102 of the drainage tray 95 where hair dust does not easily collect, the entrance corner portion of the dust receiving recess 104 Since the 105 can be formed into an inner corner shape that prevents hair from accumulating and is easy to clean, the drain tray 95 can be easily cleaned.

If the charger main body 18 is provided with a pressing body 111 that presses and urges the drain tray 95 against the support wall 110, it is possible to prevent the drain tray 95 from inadvertently rattling in the vertical direction. It is possible to prevent the water stored in the drainage tray 95 from spilling from the drainage tray 95 at times. The frictional resistance between the lower surface of the drainage tray 95 and the contact surface between the support wall 110 can give the user an appropriate feeling of operation when attaching and detaching the drainage tray 95, so that the user can increase the attachment / detachment operation speed of the drainage tray 95. It can be expected to be controlled, whereby water can be prevented from spilling due to the drainage tray 95 being quickly pulled out and separated, and damage to the drainage tray 95 can be prevented from being quickly inserted and attached to the drainage tray 95.

The pressing body 111 is integrally provided with a fixing portion 112, a pressing portion 113, and an elastic arm 114 that can be elastically deformed to connect the fixing portion 112 and the pressing portion 113, and the tray is placed on the upper surface of the drainage tray 95.

Two elastic arms 114 are extended from the fixed portion 112, and the tip of each elastic arm 114 is continuous with the end of the pressing portion 113 formed in the shape of a strip that curves downward toward the drain tray 95. The composition can be taken. 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 enhanced. 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 fixed more stably as the outer shape thereof is formed larger, and the elastic arm 114 can be elastically deformed more flexibly, but a space for fixing the fixing portion 112 is provided by that amount. It is necessary and the entire charger becomes large. On the other hand, as in the present invention, the drainage port 94 of the bottom wall 49 is provided in the flow path opening 115 of the fixed portion 112 formed in an endless annular shape.
When the fixing portion 112 is fixed to the charger main body 18 in a state where the fixing portion 112 faces, the central portion of the fixing portion 112 which becomes a dead space can be used as a flow path for drainage while increasing the outer shape of the fixing portion 112. Therefore, the entire charger can be made compact while allowing the elastic arm 114 to be elastically deformed more flexibly.

When a pair of elastic arms 114 and a pair of pressing portions 113 are provided on the fixing portion 112 so as to face each other with the fixing portion 112 in between, the drainage tray 95 is supported at two places on the support wall 1.
Since it can be pushed down and urged toward 10, it is possible to more reliably prevent the drainage 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 body 18 is provided with a drainage cylinder 96 that guides the water drained from the drainage port 94 to the drainage tray 95, and when the fixing portion 112 is fixed to the drainage cylinder 96, the structural frame of the charger is provided. Since the fixing portion 112 can be supported and fixed by the charger main body 18, the pressing body 111
Can be fixed more firmly. Therefore, it is possible to exert a more accurate position holding function and moderation function.

Raised wall 133 and conduction plate 1
There is also an advantage that the heat transfer loss between the two 133 and 135 can be reduced due to the separation from the 35.

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 back surface of the raised wall 133, the razor head 2 comes into contact with the raised wall 133 when the electric shaver is inserted and mounted on the mounting portion 21. Even in this case, since the crank-shaped cross section exhibits springiness, it is possible to prevent the conductive plate 135 from buckling and deforming. When the raised wall 133 has a straight cross section, if the raised wall 133 is stretched and deformed so as to extend upward, the conducting plate 135 may come off from the insertion groove 140. On the other hand, in the present invention, since the bent portion is formed in the middle portion of the conduction plate 135, only the raised wall 133 above the bent portion is stretched and deformed, and the stretch margin is reduced, so that the conduction plate 135 is inserted into the insertion groove. It is possible to prevent the device from coming off from 140.

When the heat transfer plate 134 is fixed to the plate fixing seat 141 of the charger main body 18, the heat transfer plate 134 can be firmly supported and fixed, so that the shape of the raised wall 133 can be held more accurately.

If the heating means is provided with a metal protective plate 129 between the bottom wall 49 and the heater 128, even if an electric razor falls on the bottom wall 49, the heater 1 is provided by the protective plate 129.
28 can be protected. 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, and the protective plate 129 can be received. Heater 12 due to the provision of
It is possible to almost eliminate the decrease in heat conduction efficiency from 8 to the heat transfer plate 134.

The urging member 77 is composed of 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-shaped arm portion 74 is elastically deformable, the terminal portion 72 is advanced and urged by the elasticity of the arm portion 74, and therefore the arm portion 74 also functions as an urging member 77. According to such a power feeding terminal 71, since the arm portion 74 can be used as the urging member 77, the compression coil spring 77 can be omitted. In this case, the compression coil spring 7
Since it is not necessary to provide the number 7, the structure around the power supply terminal 71 can be simplified and the manufacturing cost of the charger can be reduced. Further, even when the compression coil spring 77 is provided, the spring rate of the compression coil spring 77 can be reduced, and the assembling property of the power feeding terminal 71 and the compression coil spring 77 can be improved.

The terminal portion 72 is formed with an annular mountain portion 80 projecting toward the power receiving terminal 15 side and a mortar-shaped valley portion 81 surrounded by the mountain portion 80. The power receiving terminal 15 is a hemispherical contact portion 16.
Engages with the terminal portion 72 in a state of getting over the mountain portion 80 and fitting into the mortar-shaped valley portion 81. In this way, when the annular mountain portion 80 and the mortar-shaped valley portion 81 surrounded by the mountain portion 80 are formed on the terminal portion 72, the power feeding terminal 71 moves in the engaging direction at the mountain portion 80. Can be regulated to accurately hold the electric razor in the proper charging position. Further, when the power receiving terminal 15 gets over the mountain portion 80 and falls into the valley portion 81, a sense of moderation can be given, and the user can be made to recognize that the electric shaver is installed at an appropriate charging position. Further, regardless of the engaging / disengaging direction of the power receiving terminal 15 with respect to the terminal portion 72, the same sense of moderation can be obtained, and the power receiving terminals 15 can be separated by the same operating 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 of being fitted into the mortar-shaped valley portion 81, the contact portion 16 and the valley portion 81 can be brought into linear contact in a circular shape. Therefore, it is possible to accurately contact the two 15 and 81 to reduce the electric resistance at the contact portion.

As described above, when the annular (annular) mountain portion 80 is formed on the terminal portion 72, the structural strength of the terminal portion 72 can be increased, so that the charging operation can be stably executed for a long period of time. Yamabe 8
0 can also be formed into a triangular ring, a square ring, or a polygonal ring. In this case, when the power receiving terminal 15 engages with the terminal portion 72, the sense of moderation changes depending on whether the power receiving terminal 15 gets over the side portion or the corner portion, and when the power receiving terminal 15 is separated from the terminal portion 72, the side The separation operation force changes depending on whether the part is overcome or the corner is overcome.

Each of the outer slope 82 and the inner slope 83 of the mountain portion 80 is composed of a tapered surface, and the downward inclination angle of the outer slope 82 is the downward inclination angle of the inner slope 83 with respect to the plane passing through the apex of the mountain portion 80. 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 overcoming resistance becomes relatively large, so that a certain sense of moderation can be obtained, and the user can obtain an electric shaver. You can clearly recognize that it is installed in the charging position. Further, when the contact portion 16 is separated from the valley portion 81 by overcoming the inner slope 83, the overcoming resistance is relatively small, so that the separation operation force can be reduced, and the user can use an electric shaver with a light force. It can be removed. Since the timing at which the contact portion 16 gets over the mountain portion 80 at the time of engagement is during the mounting operation of the electric razor with respect to the mounting portion 21, even if the riding resistance is relatively large, the contact portion 16 easily contacts 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 tubular portion 84 continuously on the hem portion of the outer slope 82. The arm portion 74 is integrally connected to the hem portion of the tubular portion 84. Further, a regulation portion 85 is formed by bending at the hem portion of the cylinder portion 84 on the side opposite to the arm portion 74, and the regulation portion 85 is formed by bending the terminal opening 7.
By contacting the inner stage portion of No. 6, the advance limit of the terminal portion 72 is defined. Power supply terminal 71
Is formed by bending and drawing a blank material made of a metal plate punched into a predetermined shape by a pressing device. By providing the continuous tubular portion 84 at the hem portion of the outer slope 82 of the mountain portion 80 in this way, the structural strength of the terminal portion 72 can be further enhanced, and the charging operation can be stably executed for a longer period of time.

The majority portion (one end side) on the terminal portion 72 side of the compression coil spring 77 described above is the tubular portion 84.
It is provided in a state of being housed in. Further, the end turn portion of the compression coil spring 77 on the terminal portion 72 side is received by the bottom surface of the annular valley-shaped receiving recess 86 formed on the inner surface side of the mountain portion 80.
In this way, when the terminal portion 72 is urged toward the electric shaver with one end of the compression coil spring 77 housed in the tubular portion 84, the movement of the compression coil spring 77 can be restricted by the tubular portion 84, so that the compression coil The repulsive force of the spring 77 can be accurately received and the terminal portion 72 can be reliably advanced and urged.
There is also an advantage that the compression coil spring 77 can be stably supported. Further, when the end turn portion of the compression coil spring 77 housed in the tubular portion 84 is received by the annular valley-shaped receiving recess 86, the movement of the compression coil spring 77 can be more reliably regulated, so that the compression coil spring 77 can be regulated more reliably. The repulsive force of the terminal portion 72 can be more accurately received and the terminal portion 72 can be more reliably advanced and urged. There is also an advantage that the compression coil spring 77 can be supported more stably.

Specifically, the fixing portion 73 is provided with a through hole 90 penetrating the plate surface, and the terminal fixing seat 89 is oriented in a direction (rear direction) orthogonal to the exit / exit direction (left-right direction) of the terminal portion 72. A fixing pin (fixing tool) 91 having an axial center is projected. The fixing pin 91 is inserted through the through hole 90 to fix the fixing portion 7.
The fixing portion 73 can be fixed to the terminal fixing seat 89 by bringing 3 into close contact with the terminal fixing seat 89 and melting and deforming the tip of the fixing pin 91 in this state. In addition, instead of the fixing pin, the through hole 9
The fixture 91 can also be configured with screws or the like that are screwed and fixed to the terminal fixing seat 89 via 0.

As described above, when the axial direction of the fixing pin 91 for fixing the fixing portion 73 to the inner housing 25 (charger main body 18) and the exit / exit 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 as the 72 moves in and out, the fixing pin 9
A force in the shear direction acts on 1. 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 move back and forth accurately. Conversely, fixing pin 9
When the axial direction of 1 and the exit / exit direction of the terminal portion 72 are made parallel to each other, for example, when the fixing pin 91 is a screw, the screw is fastened to the screw as the terminal portion 72 moves in / out. Since the force along the line acts, the screw may gradually loosen.

The exit / exit direction of the terminal portion 72 and the extension direction of the fixing portion 73 are the same direction (horizontal direction), and both 72 and 73 are arranged at positions shifted back and forth, and the axial direction of the fixing pin 91 (front and back). direction)
Is configured to be orthogonal to the exit / exit direction of the terminal portion 72 and the extension direction of the fixed portion 73. The extension 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 integrally formed in the shape of a bent plate and the arm portion 74 is an obtuse angle. It is set to be. According to this, the total length of the arm portion 74 can be formed longer than in the case where the internal angle θ is set at a right angle, and the arm portion 74 accompanying the moving of the terminal portion 72 in and out can be formed.
The amount of elastic deformation of the arm portion 74 can be reduced to avoid fatigue fracture of the arm portion 74 due to repeated elastic deformation. Further, even when the internal angle θ is set to an acute angle, the total length of the arm portion 74 can be formed to be long, but in this case, the boundary portion between the fixed portion 73 and the arm portion 74 (an acute-angled bent portion). There is a disadvantage in that fatigue fracture is likely to occur.

In this embodiment, the total force of the urging force of the urging member (compression coil spring 77 and arm portion 74) that urges each power supply terminal 71 to advance urges the detection switch 55 (movable spring). 5
It is set larger than the urging force of 8. By setting the urging force of each of the urging members 58 and 77 in this way, it is possible to sandwich the electric razor with a larger urging force and prevent the electric razor from floating away from the wall surface.
Further, as described above, the electric razor mounted at an appropriate charging position of the mounting portion 21 leans against the rear wall surface 50. Therefore, in a halfway mounting position where the entire electric shaver is vertically inverted (not tilted backward), even if the power receiving terminal 15 and the power feeding terminal 71 are in contact with each other, the detection switch 55 Is not switched to the on state, so no charging current is supplied.

It is possible to prevent the drainage tray 95 from being damaged due to water spilling or the drainage tray 95 being quickly inserted and attached.

A circumferential fixed seat 116 is formed on the outer peripheral surface of the drainage cylinder 96 described above, and the drainage cylinder 96 is formed.
Is formed in a stepped cylindrical shape, and by fixing the fixing portion 112 to the fixing seat 116,
The pressing body 111 is fixed to the charger body 18. The fixing portion 112 is fixed to the base frame 19 in a state where the drain port 94 of the bottom wall 49 faces the flow path opening 115 of the fixing portion 112. Specifically, the fixing portion 112 is formed with through holes 117 at each of the four corners, and the fixing seat 116 is formed.
Fixing pins 118 are projected upward at positions corresponding to the through holes 117.
The upper half of the drainage cylinder 96 is inserted into the flow path opening 115 of the fixing portion 112, and the fixing portion 11 is inserted into the drainage cylinder 96.
2 is fitted on the outside. Further, the fixing portion 112 is brought into close contact with the fixing seat 116, and in this state, the fixing pin 1
By melting and deforming the tip of 18, the fixing portion 112 can be fixed to the fixing seat 116. Instead of the fixing pin 118, the pressing body 111 can be fixed by a screw or the like that is screwed and fixed to the fixing seat 116 through the through hole 117.

The fixing portion 112 of the pressing body 111 can be fixed more stably as the outer shape thereof is formed larger, and the elastic arm 114 can be elastically deformed more flexibly, but a space for fixing the fixing portion 112 is provided by that amount. It is necessary and the entire charger becomes large. However, as in the present embodiment, when the fixing portion 112 is fixed to the base frame 19 in a state where the drainage port 94 of the bottom wall 49 faces the flow path opening 115 of the fixing portion 112 formed in an endless ring shape, the fixing portion 112 Although the outer shape is enlarged, the central portion of the fixed portion 112, which is a dead space, can be used as a flow path through which drainage passes. Therefore, the entire charger can be made compact while allowing the elastic arm 114 to be elastically deformed flexibly.

The tip of the protrusion of each pressing portion 113 projects to the tray mounting portion 98 through the exposed hole 119 provided in the base frame 19, and the protruding portion of the pressing portion 113 is an engagement formed in the drainage tray 95. It is engaged with the recess 120. The engaging recess 120 is composed of a recess formed in the upper surface of the peripheral side wall 101 and the flange wall 103, and the drainage tray 95 is a tray mounting portion 98.
The pressing portion 113 is depressed and engaged with the engaging recess 120 in the state of being mounted on the engaging portion 113. In this way, when the engaging recess 120 in which the pressing portion 113 falls and engages is formed on the upper surface of the drainage tray 95 when the tray 95 is in the mounting position, the drainage tray 95 can be held in the mounting position. can. Further, in attaching / detaching the drainage tray 95, when the pressing portion 113 comes out of the engaging recess 120 at the start of the drawer separation and at the end of the insertion mounting, the pressing portion 113
The user feels a sense of operation of the drain tray 95 when the material falls into the engaging recess 120, so that 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 drainage tray 95 can be combined, there is an advantage that the number of parts can be reduced and the manufacturing cost can be reduced.

Two elastic arms 114 are extended from the fixed portion 112, and the tip of each elastic arm 114 is continuous with the end of the pressing portion 113 formed in the shape of a strip that curves downward toward the drain tray 95. Therefore, the fixing portion 112, the elastic arm 114, and the pressing portion 113 are formed in a frame shape. As a result, the structural strength of the pressing body 111 can be increased, and the elastic arm 114 can be elastically deformed more flexibly, so that an accurate position holding function and a clear moderation function can be exhibited. A pair of elastic arms 1 face the fixed portion 112 so as to face the fixed portion 112 with the fixed portion 112 in between.
Since a set of 14 and a pressing portion 113 are provided, the drain tray 95 is provided at two locations.

The base frame 19 is provided with a drainage cylinder 96 that guides the water drained from the drainage port 94 to the drainage tray 95, and when the fixing portion 112 of the pressing body 111 is fixed to the drainage cylinder 96, the structural 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 more accurate position holding function and clear moderation function can be exhibited.
Further, when the fixing portion 112 of the pressing body 111 is fixed to the fixed seat 116 of the drainage cylinder 96 while the flow path opening 115 of the pressing body 111 is fitted onto the drainage cylinder 96, the fixing portion 112 is the cylinder of the drainage cylinder 96. Since the pressing body 111 is supported and fixed while being restricted from moving in the direction orthogonal to the axis, the pressing body 111 can be fixed more firmly.

The charger main body 18 is provided with a power socket 123 for receiving power to receive the drive power of the charger, and the connection plug 1 provided at one end of the power cord in the power socket 123.
24 are plugged in and connected. The power cord on the other end 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 body 18 is assumed in a plan view of the charger, the right side (one side) of the charger body 18 divided by the virtual line V is assumed. Tray opening 97 is placed in the area of
The power socket 123 is arranged in the area on the left side (the other side).

When the tray opening 97 is arranged in the area on the right side of the charger body 18 divided by the virtual line V as described above and the power socket 123 is arranged in the area on the left side, the tray opening 97 and the power socket 1 are arranged.
Even if water spills when the drain tray 95 is separated by keeping the distance from 23 as far as possible, the power socket 123 will not be splashed with water. Therefore, it is possible to effectively prevent short circuits and corrosion from occurring in the power socket 123. When assuming the above virtual line V and the second virtual line that passes through the center of the charger body 18 and is orthogonal to the virtual line V, the tray opening 97 and the power socket 123 are arranged in the diagonal quadrant region. You can also do it. In this case, both 97.1
By further moving the 23 away, it is possible to further suppress water from adhering to the power socket 123 when the drain tray 95 is attached or detached.

The connection plug 124 is plugged and connected to the power socket 123 from the rear to the front. As a result, 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 to be parallel to the mounting surface of the charger (horizontal direction). As described above, the attachment / detachment direction of the drainage tray 95 is orthogonal to the flow direction of the water flowing through the drainage port 94.
The drainage tray 95 is configured to be attached / detached, the connection plug 124 is inserted, and the drainage port 94 is configured to be orthogonal to each other.

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

The power socket 123 is provided in the inner inner part of the socket recess 125 formed in the charger main body 18.

Accelerates the drying of the razor head 2. However, the main blade 4 and the trimmer unit 5 provided in the cutting blade portion 3 have a precise 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 it will take time to dry. Therefore, in this embodiment, the bottom wall 49 is provided with a raised wall 133 facing the front surface 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 faces the front surface of the trimmer unit 5 in close contact with each other. The raised wall 133 can be provided so as to face the back surface of the cutting blade portion 3, and 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 facing the left and right side surfaces of the tip of the razor head 2 can also 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 body, and has a conductive plate 135 extending upward along the raised wall 133 and a heat receiving plate connected to the lower end of the conductive plate 135 to receive the heat of the heater 128. It is equipped with a plate 136. Conduction plate 13
Reference numeral 5 denotes a crank shape formed along the back surface of the raised wall 133, and is in close contact with the back surface of the raised wall 133. Insertion grooves 140 are provided on the upper surface of 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 in. The heat receiving plate 136 is in close contact with the upper surface of the front side of the protective plate 129, and the heat of the heater 128 is conducted to the heat transfer plate 134 through the protective plate 129. The conduction plate 135 may be provided on the back surface of the raised wall 133 in a state of facing each other with a slight gap.

As described above, if 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 highly flexible material can be held by the conductive plate 135, and the raised wall 133 can be cut by the cutting blade. It is possible to accurately face the front of the part 3. Further, the heat of the conduction plate 135 can be efficiently transferred to the raised wall 133. Therefore, the cutting blade portion 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 conduction 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. Therefore, the shape of the raised wall 133 can be held more accurately. There is also an advantage that the heat transfer loss between the two 133 and 135 can be reduced because the raised wall 133 and the conduction plate 135 are separated from each other.
Further, when the raised wall 133 is raised upward in a cross-sectional crank shape and the conduction plate 135 is formed in a shape along the back surface of the raised wall 133, the razor head 2 is mounted on the mounted portion 21 by inserting the electric razor into the raised wall 133. Since the crank-shaped cross section exhibits springiness even when it comes into contact with, it is possible to prevent the conductive plate 135 from buckling and deforming. When the raised wall 133 has a straight cross section, if the raised wall 133 is stretched and deformed so as to extend upward, the conducting plate 135 may come off from the insertion groove 140. However, in this embodiment, since the bent portion is formed in the middle portion of the conduction plate 135, only the raised wall 133 above the bent portion is stretched and deformed, so that the conduction plate 135 with a smaller elongation allowance is inserted. It is possible to prevent the groove 140 from coming off.

The heat transfer plate 134 is a plate fixing seat 1 formed on the partition wall 28 of the base frame 19.
It is fixed at 41. Specifically, a pair of left and right fixed tongue pieces 137 for fixing the protective plate 129 are provided at the tip of the heat receiving plate 136. A through hole 142 penetrating the plate surface is provided in the fixed tongue piece 137, and two fixing pins 143 are projected upward in the plate fixing seat 141. The heat transfer plate 134 is attached to the base frame 19 by inserting the fixing pin 143 into each through hole 142 to bring the fixed tongue piece 137 into close contact with the plate fixing seat 141, and melting and deforming the tip of the fixing pin 143 in this state. Can be fixed. note that,
Instead of the fixing pin 143, the heat transfer plate 134 can be fixed by a screw or the like that is screwed and fixed to the plate fixing seat 141 via the through hole 142. When the heat transfer plate 134 is fixed to the plate fixing seat 141 of the base frame 19 in this way, the heat transfer plate 1
Since 34 can be firmly supported and fixed, the shape of the raised wall 133 can be held more accurately.

According to the electric razor charger provided with the above-mentioned heating means, by energizing the heater 128, the air in the mounting portion 21 is heated through the bottom wall 49 heated by the heater 128, and the razor is heated. The temperature of the entire head 2 can be raised to accelerate the drying of the razor head 2 after washing with water. 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 to effectively wash the razor head 2 with water. Drying can be promoted.
Also, if a metal protective plate 129 is provided between the bottom wall 49 and the heater 128,
Even if the electric razor falls on the bottom wall 49, the protective plate 129 can protect the heater 128. In addition, the heat receiving plate 136 of the heat transfer plate 134 is placed on the plate surface of the protective plate 129.
When they are brought into close contact with each other, the heat of the heater 128 is received by the heat receiving plate 13 via the metal protective plate 129.
It can be received at No. 6, and the decrease in heat conduction efficiency from the heater 128 to the heat transfer plate 134 due to the provision of the protective plate 129 can be almost eliminated.
In this embodiment, since a sheathed heater having a circular cross section is used for the heater 128, when the heater 128 is brought into direct contact with the bottom wall 49, both 49 and 128 come into contact with each other in a line contact manner. However, by interposing a metal protective plate 129 between the two 49 and 128, the heat of the heater 128 can be conducted to a wider range of bottom wall 49 through the protective plate 129, so that the bottom wall 49 can be provided. It can be heated efficiently.

In the above embodiment, the connection plug 124 on one end side of the power cord is connected to the power socket 123, the plug on the other end side of the power cord is connected to the outlet of the commercial power supply, and then the electric shaver in the inverted position is attached. The charger is configured so that the detection switch 55 is turned on and the charging operation for the electric shaver is automatically started by inserting it into the unit 21 and tilting it backward. In this way, instead of the operation mode of the charger in which the charging operation is automatically started when the detection switch 55 is switched to the ON state, the electric razor is mounted at an appropriate charging position of the mounting portion 21 and the detection switch. In a state where the 55 is switched to the on state, the charging operation can be started when the switch element 32 is manually pushed (on operation). Further, when the switch element 32 is pushed, the 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 sterilizing operations can be performed. In this operation mode, the three modes of standby, charging mode, and 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 operation mode, the charging operation is unnecessarily performed when the electric razor having a sufficient remaining charge of the secondary battery 13 is attached to the mounting portion 21 for storage. It is possible to suppress deterioration of the secondary battery 13 due to frequent repetition of a short-time charging operation. When the remaining charge of the secondary battery 13 is less than, for example, 40%, the charging operation may be started without pushing the switch element 32.

Japanese Unexamined Patent Publication No. 2008-18128

An object of the present invention is to provide a charger capable of smoothly attaching and detaching a drain tray.

The charger for a small electric device of the present invention includes a charger body 18 having a mounting portion 21 that allows the small electric device to be mounted. A drainage port 94 is provided on the bottom wall 49 of the mounting portion 21. The charger main body 18 is provided with a drain tray 95 for receiving the water flowing down from the drain port 94. The drainage tray 95 is detachably attached to a tray mounting portion 98 having a tray opening 97 that opens on the peripheral side surface of the charger main body 18. The attachment / detachment direction of the drainage tray 95, which is attached / detached via the tray opening 97, is set to be parallel to the mounting surface of the charger. A connection plug 124 provided at one end of the power cord is plugged and connected to the power receiving power socket 123 provided in the charger main body 18. It is characterized in that the attachment / detachment direction of the drainage tray 95 and the insertion direction of the connection plug 124 are orthogonal to each other.

The insertion direction of the connection plug 124 is set to be parallel to the mounting surface of the charger.

Assuming a virtual line V passing through the center of the charger body 18 in a plan view of the charger, a tray opening 97 is arranged in one area of the charger body 18 divided by the virtual line V, and a tray opening 97 is arranged in the other area. The power socket 123 is arranged.

The power socket 123 is provided in the inner inner part of the socket recess 125 formed in the charger main body 18. The inner peripheral wall of the socket recess 125 is formed in a constricted shape toward the inner back in the insertion direction of the connection plug 124.

In the charger of the small electric device of the present invention, the attachment / detachment direction of the drainage tray 95 attached / detached through the tray opening 97 is set to be parallel to the mounting surface of the charger, and the drainage tray 95 is attached / detached. The attachment / detachment direction and the insertion direction of the connection plug 124 are configured to be orthogonal to each other. According to such a drainage tray 95, the drainage tray 95 can be attached and detached without lifting the charger, and the water stored in the drainage tray 95 can be easily disposed of. Further, there is an advantage that the drainage tray 95 can be smoothly attached / detached as compared with the case where the drainage tray 95 is attached / detached while being pulled up diagonally upward or diagonally downward with respect to the mounting surface.

If the attachment / detachment direction of the drain tray 95 and the insertion direction of the connection plug 124 that is plugged and connected to the power socket 123 are orthogonal to each other, the drain tray 95 is separated while holding the power cord. However, it is possible to effectively prevent the inconvenience that the connection plug 124 comes off. Therefore, even when the drainage tray 95 is full and the drainage tray 95 needs to be separated during charging of the small electric device, it is possible to prevent the charging operation of the small electric device from being interrupted. For example, when the attachment / detachment direction of the drainage tray 95 and the insertion direction of the connection plug 124 are opposite to each other, if the drainage tray 95 is separated while holding the power cord, the connection plug 124 will come off and the charging operation will be performed. May stop.

When the insertion direction of the connection plug 124 is set to be parallel to the mounting surface of the charger, the connection plug 124 is pulled up diagonally upward or diagonally downward with respect to the mounting surface, as in the case of the drain tray 95 above. However, as compared with the case where the drain tray 95 is attached / detached, the connection plug 124 can be attached / detached more smoothly.

Assuming a virtual line V passing through the center of the charger body 18 in the plan view of the charger, the tray opening 97 is arranged in one area of the charger body 18 divided by the virtual line V, and the tray opening 97 is arranged in the other area. A form in which the power socket 123 is arranged can be adopted. According to this, the distance between the tray opening 97 and the power socket 123 can be made as far as possible, so that even if water spills when the drain tray 95 is separated, the power socket 123 can be prevented from being splashed with water. Can be done. Therefore, it is possible to prevent problems such as short circuit and corrosion from occurring in the power socket 123.

The power socket 123 is provided in the inner inner part of the socket recess 125 formed in the charger main body 18, and the inner peripheral wall of the socket recess 125 is formed in a constricted shape toward the inner inner part in the insertion direction of the connection plug 124. It can take the form that is done. According to this, since the inlet side of the socket recess 125 can be widened and the inner inner portion can be narrowed, the connection plug 124 is inserted into the socket recess 125 at the initial stage of connection of the connection plug 124 to the power socket 123. It is easy to prevent the connection plug 124 from interfering with the outer surface of the charger body 18. Further, in the middle stage of connection of the connection plug 124, the connection plug 124 is guided by the wall surface and can be inserted so that the connection plug 124 approaches the socket recess 125, making it easy to connect the connection plug 124 to the power socket 123. Can be converted.

The electric razor can be attached to the attachment portion 21 by the following procedure. first,
The electric razor is in an inverted posture in which the razor head 2 is located on the lower side with the front surface facing 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 portion on the front side of the upper opening, and further, as shown by the arrow in FIG. 5, the electric razor is set with the tip (lower side) of the razor head 2 as a fulcrum. The whole body is tilted backward, and the main body 1 is moved to the rear narrow portion of the upper opening. As a result, the electric shaver is mounted at an appropriate charging position of the mounting portion 21. In the electric razor mounted at the charging position, the tip of the razor head 2 is the mounting portion 21 in a state where the razor head 2 is restricted from moving forward by a pair of left and right positioning ribs indicated by reference numerals 48 in FIGS. 3 and 5. It is received by the bottom wall 49 (bottom housing 26) of the. 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 shaver is tilted backward. The main body 1 faces the rear wall surface (wall surface) 50 of the mounting portion 21, the left wall surface (wall surface) 51 and the right wall surface (wall surface) 52 in the rear narrow portion of the upper opening, and each wall surface 50.
The upper end portions of 51 and 52 are in contact with the outer surface of the main body portion 1, and the movement of the main body portion 1 in the rear direction and the left-right direction 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 the bottom wall 49 of the mounting portion 21, and is made of a molded product made of an elastomer (elastic body) which is rich in flexibility, heat resistance, and has good thermal conductivity. By using an elastomer as the material forming the bottom housing 26, the impact acting on the razor head 2 when the electric razor is received by the bottom wall 49 of the mounting portion 21 is alleviated, and the surface of the cutting blade portion 3 is scratched. Etc. can be prevented.

The charging, drying, and sterilizing operations by the charger are configured to be performed when the electric razor is mounted in the proper charging position of the mounting section 21. Therefore, the mounting unit 2
One detection switch 55 that detects that the electric razor is properly installed at the charging position of 1.
Is arranged at the vertical center position of the rear wall surface 50 of the mounting portion 21. As shown in FIGS. 5 and 6, the detection switch 55 is mounted by a contact body 56 that is freely guided by the rear wall surface 50 of the mounting portion 21 and a switch body 57 that is turned on and off by the contact body 56. It is provided with an urging member 58 or the like for advancing and urging the contact body 56 toward the electric shaver mounted on the portion 21. Switch body 5
Reference numeral 7 denotes a micro switch, and a movable spring 58 that takes a snap action of the actuator portion 59 of the switch functions as an urging member. If the urging force for advancing the contact body 56 is insufficient with only the movable spring 58, an urging member 58 made of a compression coil spring, a leaf spring, or the like may be separately provided. The control board 31 executes each operation of charging, drying, and sterilizing when the switch body 57 is switched from the off state to the on state.

The switch body 57 is held and fixed inside a square box-shaped switch case 62 having an open front surface, 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 whose central portion in the vertical direction bulges forward, and a pair of upper and lower connecting walls 64 extending backward from the upper and lower ends of the contact base 63. There is.
Guide claws 65 are 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. The contact body 56 is supported by the guide claws 65 and the guide groove 66 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 move-out direction (front-back direction) is restricted. The contact body 56 is a rear wall surface 5 of the inner housing 25.
It is arranged so as to be fitted in the switch opening 67 opened at 0, and the contact body 56 is guided and supported on the inner peripheral surface of the switch opening 67 so as to be freely retractable. In this embodiment, the switch body 57 is composed of a micro switch, but the switch body 57 can be composed of a tact switch that is pushed in at the retracted end of the contact body 56. In this case, the contact body 56 may be separately urged in the advancing direction by a 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 having rounded tips extending in the vertical direction (the direction in which the electric razor is inserted). There is. The upper end of the rear surface of the main body 1 comes into contact with the contact surface, and the contact body 56 is pushed backward. As described above, when the contact portion of the contact body 56 constituting the detection switch 55 is composed of a plurality of ribs 68 extending in the vertical direction, the contact area between the electric shaver and the contact portion can be reduced as much as possible. As a result, it is possible to suppress scratches due to friction between the electric razor and the contact portion during attachment / detachment. Further, by rounding the tip of the rib 68, the contact area can be further reduced, and the damage to 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 a water-washed electric shaver is mounted on the mounting portion 21 as in this embodiment, the water adhering to the contact body 56 is allowed to flow downward through between the adjacent ribs 68 and 68. Therefore, it is possible to prevent the detection switch 55 from malfunctioning due to the accumulation of water around the detection switch 55, and to improve the safety of the charger. If the plurality of ribs 68 are formed so as to cross the insertion direction of the electric razor, 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 feeding terminals 71 in order to supply a charging current to the electric shaver mounted at the charging position. Power supply terminal 7 as shown in FIGS. 4 and 5
1 is provided on the left and right wall surfaces 51 and 52 of the mounting portion 21 that sandwiches the main body portion 1, respectively. As shown in FIGS. 1 and 7, each power supply terminal 71 has a terminal portion 72 that engages with the power receiving terminal 15 of the electric shaver, a fixing portion 73 for fixing the power supply terminal 71 to the charger main body 18, and one end thereof. An arm portion 74 that is connected to the terminal portion 72 and the other end is connected to the fixed portion 73 to support the terminal portion 72 so as to be swing-displaceable with respect to the fixed portion 73, and a fixed portion 73 on the other end side of the arm portion 74. It is integrally provided with a lead connecting portion 75 which is connected to the lead wire and is connected to the lead wire. Fixed part 73, arm part 74
, And the lead connecting portion 75 is formed in a plate shape, the arm portion 74 is bent forward with respect to the fixing portion 73, and the lead connecting portion 75 is bent backward. As a result, the fixed portion 7
3. The arm portion 74 and the lead connecting portion 75 are integrally bent in a crank shape.

The terminal portion 72 of each power supply terminal 71 is supported by the arm portion 74 so as to face the terminal openings 76 provided on the left and right wall surfaces 51 and 52, and is supported in the advancing direction (electric shaver 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 is composed of 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-shaped arm portion 74 is elastically deformable, the terminal portion 72 is advanced and urged by the elasticity of the arm portion 74, and therefore the arm portion 74 also functions as an urging member 77. According to such a power feeding terminal 71, since the arm portion 74 can be used as the urging member 77, the compression coil spring 77 can be omitted. In this case, the compression coil spring 7
Since it is not necessary to provide the number 7, the structure around the power supply terminal 71 can be simplified and the manufacturing cost of the charger can be reduced. Further, even when the compression coil spring 77 is provided, the spring rate of the compression coil spring 77 can be reduced, and the assembling property of the power feeding terminal 71 and the compression coil spring 77 can be improved.

The terminal portion 72 is formed with an annular mountain portion 80 projecting toward the power receiving terminal 15 side and a mortar-shaped valley portion 81 surrounded by the mountain portion 80. The power receiving terminal 15 is a hemispherical contact portion 16.
Engages with the terminal portion 72 in a state of getting over the mountain portion 80 and fitting into the mortar-shaped valley portion 81. In this way, when the annular mountain portion 80 and the mortar-shaped valley portion 81 surrounded by the mountain portion 80 are formed on the terminal portion 72, the power feeding terminal 71 moves in the engaging direction at the mountain portion 80. Can be regulated to accurately hold the electric razor in the proper charging position. Further, when the power receiving terminal 15 gets over the mountain portion 80 and falls into the valley portion 81, a sense of moderation can be given, and the user can be made to recognize that the electric shaver is installed at an appropriate charging position. Further, regardless of the engaging / disengaging direction of the power receiving terminal 15 with respect to the terminal portion 72, the same sense of moderation can be obtained, and the power receiving terminals 15 can be separated by the same operating 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 of being fitted into the mortar-shaped valley portion 81, the contact portion 16 and the valley portion 81 can be brought into linear contact in a circular shape. Therefore, it is possible to accurately contact the two 15 and 81 to reduce the electric resistance at the contact portion.

As described above, when the annular (annular) mountain portion 80 is formed on the terminal portion 72, the structural strength of the terminal portion 72 can be increased, so that the charging operation can be stably executed for a long period of time. Yamabe 8
0 can also be formed into a triangular ring, a square ring, or a polygonal ring. In this case, when the power receiving terminal 15 engages with the terminal portion 72, the sense of moderation changes depending on whether the power receiving terminal 15 gets over the side portion or the corner portion, and when the power receiving terminal 15 is separated from the terminal portion 72, the side The separation operation force changes depending on whether the part is overcome or the corner is overcome.

Each of the outer slope 82 and the inner slope 83 of the mountain portion 80 is composed of a tapered surface, and the downward inclination angle of the outer slope 82 is the downward inclination angle of the inner slope 83 with respect to the plane passing through the apex of the mountain portion 80. 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 overcoming resistance becomes relatively large, so that a certain sense of moderation can be obtained, and the user can obtain an electric shaver. You can clearly recognize that it is installed in the charging position. Further, when the contact portion 16 is separated from the valley portion 81 by overcoming the inner slope 83, the overcoming resistance is relatively small, so that the separation operation force can be reduced, and the user can use an electric shaver with a light force. It can be removed. Since the timing at which the contact portion 16 gets over the mountain portion 80 at the time of engagement is during the mounting operation of the electric razor with respect to the mounting portion 21, even if the overcoming resistance is relatively large, the contact portion easily comes into contact 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 tubular portion 84 continuously on the hem portion of the outer slope 82. The arm portion 74 is integrally connected to the hem portion of the tubular portion 84. Further, a regulation portion 85 is formed by bending at the hem portion of the cylinder portion 84 on the side opposite to the arm portion 74, and the regulation portion 85 is formed by bending the terminal opening 7.
By contacting the inner stage portion of No. 6, the advance limit of the terminal portion 72 is defined. Power supply terminal 71
Is formed by bending and drawing a blank material made of a metal plate punched into a predetermined shape by a pressing device. By providing the continuous tubular portion 84 at the hem portion of the outer slope 82 of the mountain portion 80 in this way, the structural strength of the terminal portion 72 can be further enhanced, and the charging operation can be stably executed for a longer period of time.

The majority portion (one end side) on the terminal portion 72 side of the compression coil spring 77 described above is the tubular portion 84.
It is provided in a state of being housed in. Further, the end turn portion of the compression coil spring 77 on the terminal portion 72 side is received by the bottom surface of the annular valley-shaped receiving recess 86 formed on the inner surface side of the mountain portion 80.
In this way, when the terminal portion 72 is urged toward the electric shaver with one end of the compression coil spring 77 housed in the tubular portion 84, the movement of the compression coil spring 77 can be restricted by the tubular portion 84, so that the compression coil The repulsive force of the spring 77 can be accurately received and the terminal portion 72 can be reliably advanced and urged.
There is also an advantage that the compression coil spring 77 can be stably supported. Further, when the end turn portion of the compression coil spring 77 housed in the tubular portion 84 is received by the annular valley-shaped receiving recess 86, the movement of the compression coil spring 77 can be more reliably regulated, so that the compression coil spring 77 can be regulated more reliably. The repulsive force of the terminal portion 72 can be more accurately received and the terminal portion 72 can be more reliably advanced and urged. 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, the fixing portion 73 is provided with a through hole 90 penetrating the plate surface, and the terminal fixing seat 89 is oriented in a direction (rear direction) orthogonal to the exit / exit direction (left-right direction) of the terminal portion 72. A fixing pin (fixing tool) 91 having an axial center is projected. The fixing pin 91 is inserted through the through hole 90 to fix the fixing portion 7.
The fixing portion 73 can be fixed to the terminal fixing seat 89 by bringing 3 into close contact with the terminal fixing seat 89 and melting and deforming the tip of the fixing pin 91 in this state. In addition, instead of the fixing pin, the through hole 9
The fixture 91 can also be configured with screws or the like that are screwed and fixed to the terminal fixing seat 89 via 0.

As described above, when the axial direction of the fixing pin 91 for fixing the fixing portion 73 to the inner housing 25 (charger main body 18) and the exit / exit 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 as the 72 moves in and out, the fixing pin 9
A force in the shear direction acts on 1. 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 move back and forth accurately. Conversely, fixing pin 9
When the axial direction of 1 and the exit / exit direction of the terminal portion 72 are made parallel to each other, for example, when the fixing pin 91 is a screw, the screw is fastened to the screw as the terminal portion 72 moves in / out. Since the force along the line acts, the screw may gradually loosen.

The exit / exit direction of the terminal portion 72 and the extension direction of the fixing portion 73 are the same direction (horizontal direction), and both 72 and 73 are arranged at positions shifted back and forth, and the axial direction of the fixing pin 91 (front and back). direction)
Is configured to be orthogonal to the exit / exit direction of the terminal portion 72 and the extension direction of the fixed portion 73. The extension 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 integrally formed in the shape of a bent plate and the arm portion 74 is an obtuse angle. It is set to be. According to this, the total length of the arm portion 74 can be formed longer than in the case where the internal angle θ is set at a right angle, and the arm portion 74 accompanying the moving of the terminal portion 72 in and out can be formed.
The amount of elastic deformation of the arm portion 74 can be reduced to avoid fatigue fracture of the arm portion 74 due to repeated elastic deformation. Further, even when the internal angle θ is set to an acute angle, the total length of the arm portion 74 can be formed to be long, but in this case, the boundary portion between the fixed portion 73 and the arm portion 74 (an acute-angled bent portion). There is a disadvantage in that fatigue fracture is likely to occur.

In this embodiment, the total force of the urging force of the urging member (compression coil spring 77 and arm portion 74) that urges each power supply terminal 71 to advance urges the detection switch 55 (movable spring). 5
It is set larger than the urging force of 8. By setting the urging force of each of the urging members 58 and 77 in this way, it is possible to sandwich the electric razor with a larger urging force and prevent the electric razor from floating away from the wall surface.
Further, as described above, the electric razor mounted at an appropriate charging position of the mounting portion 21 leans against the rear wall surface 50. Therefore, in a halfway mounting position where the entire electric shaver is vertically inverted (not tilted backward), even if the power receiving terminal 15 and the power feeding terminal 71 are in contact with each other, the detection switch 55 Is not switched to the on state, so no charging current is supplied.

In the electric razor charger of the present embodiment, power supply terminals 71 are provided on the left and right wall surfaces 51 and 52 of the mounting portions 21 facing each other with the electric razor in between, and a detection switch 55 is provided on the remaining rear wall surface 50. According to the arrangement of the power feeding terminal 71 and the detection switch 55, the power receiving terminal 1 is subjected to the urging force acting in the opposite direction by the urging members 77 of the pair of power feeding terminals 71.
The position is held by sandwiching the electric razor via 5, and it is possible to effectively prevent the electric razor from floating off the wall surface by the urging force of the urging member 58 of the detection switch 55 or the external force acting on the charger. ..

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. Further, the dust receiving recess 104 is a peripheral side wall 101.
A recess is formed in the bottom wall 102 without contacting the bottom wall 102. The curvature of the inner corner portion 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 inner corner portion 106 sandwiched between the inner peripheral surfaces of the peripheral side wall 101 and the bottom wall 102. In the inside corner portion 105 of this embodiment, since the curvature is made as small as possible, the inside corner portion 105 is configured in a substantially inclined surface shape connecting the bottom surface of the bottom wall 102 and the bottom surface of the dust receiving recess 104. A finger hook recess 107 is formed in the peripheral side wall 101 on the front and rear side facing the tray opening 97 so that the drain tray 95 can be more easily grasped by the fingertips (see FIGS. 4 and 10).

As described above, the attachment / detachment direction of the drainage tray 95 attached / detached from the tray mounting portion 98 via the tray opening 97 formed on the right peripheral side surface of the charger main body 18 is set to be parallel to the mounting surface of the charger. Then, the drainage tray 95 can be attached and detached without lifting the charger, and the water stored in the drainage tray 95 can be easily disposed of. Compared to the case where the drain tray 95 is attached / detached while pulling it diagonally upward or diagonally downward with respect to the mounting surface.
There is also an advantage that the drain tray 95 can be smoothly attached and detached.
Further, when the dust receiving recess 104 is formed as a recess in the bottom wall 102 of the drainage tray 95 facing the drain port 94, if the discharged water contains hair dust, the hair dust is collected in the dust receiving recess 104. It is possible to prevent water containing hair dust from spilling from the drainage tray 95 as much as possible, and prevent the mounting surface and the like around the charger from being soiled by hair dust.
Further, the curvature of the inner 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 inner corner portion 106 sandwiched between the inner peripheral surface of the peripheral side wall 101 and the bottom wall 102 of the drainage tray 95. When set, the entrance corner 105 of the dust receiving recess 104 is formed while increasing the capacity of the drainage tray 95 as much as possible at the entrance corner 106 between the peripheral side wall 101 and the bottom wall 102 of the drainage tray 95 where hair dust does not easily collect. Since the shape can be made so that the hair dust does not collect easily and it is easy to clean, the drain tray 95 can be easily cleaned.

As described above, the electric shaver in the mounting position moves in the rear direction and the left-right direction 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. Is regulated, and the drain tray 95 is pulled out and separated in the right direction (opposite to the movement restricting direction of the electric shaver) in the plan view of the charger. According to this, even when the electric razor is grasped and the drain tray 95 is separated, the movement of the electric razor is restricted and the proper charging position can be maintained, so that even when the drain tray 95 is separated while charging the electric razor. ,
The charging operation of the electric shaver is surely continued.

As shown in FIGS. 8 and 10, rail walls (support walls) 110 are projected inward on each of the front and rear inner wall surfaces of the tray mounting portion 98. The drainage tray 95 is a rail wall 110.
The flange wall 103 (lower surface of the drainage tray 95) of the drainage tray 95 is mounted on the tray mounting portion 98 in a state where the flange wall 103 (lower surface of the drainage tray 95) is received. Further, the rail wall 110 also serves as a guide member that slides and guides the drainage tray 95 that is inserted and mounted from the tray opening 97. Charger body 1
No. 8 is provided with a pressing body 111 that presses and urges the drainage tray 95 against the rail wall 110.

As shown in FIG. 9, the pressing body 111 includes a fixing portion 112 fixed to the base frame 19 (charger main body 18), a pressing portion 113 in contact with the drain tray 95, and the fixing portion 112 and the pressing portion 1.
It is provided with a pair of elastically deformable left and right elastic arms 114 that integrally connect with 13. The pressing portion 113 is formed in a strip shape that curves downward, and is provided so as to connect the tips of the pair of elastic arms 114. The fixing portion 112 is formed in a frame shape (endless ring shape) having a circular flow path opening 115 in the center of the plate surface. The pressing portion 113 and the pair of elastic arms 114 are formed by the fixing portion 1.
One set is provided before and after the twelve. The pressing body 111 is formed by bending a blank material made of a metal plate punched into a predetermined shape by a pressing device.

As described above, the drain tray 9 is attached to the rail wall 110 of the tray mounting portion 98 on the charger main body 18.
When the pressing body 111 that presses and urges the flange wall 103 of 5 is provided, the drainage tray 95 can be prevented from rattling in the vertical direction by the pressing body 111, so that the drainage tray 95 is unnecessarily rattled and stored during the pull-out operation. You can prevent the water from spilling. Further, the frictional resistance at the contact surface between the flange wall 103 of the drainage tray 95 and the upper surface of the rail wall 110 provides an appropriate feeling of operation when the drainage tray 95 is attached / detached, and the drainage tray 95 is quickly pulled out and separated. It is possible to prevent the drainage tray 95 from being damaged due to water spilling or the drainage tray 95 being quickly inserted and attached.

A circumferential fixed seat 116 is formed on the outer peripheral surface of the drainage cylinder 96 described above, and the drainage cylinder 96 is formed.
Is formed in a stepped cylindrical shape, and by fixing the fixing portion 112 to the fixing seat 116,
The pressing body 111 is fixed to the charger body 18. The fixing portion 112 is fixed to the base frame 19 in a state where the drain port 94 of the bottom wall 49 faces the flow path opening 115 of the fixing portion 112. Specifically, the fixing portion 112 is formed with through holes 117 at each of the four corners, and the fixing seat 116 is formed.
Fixing pins 118 are projected upward at positions corresponding to the through holes 117.
The upper half of the drainage cylinder 96 is inserted into the flow path opening 115 of the fixing portion 112, and the fixing portion 11 is inserted into the drainage cylinder 96.
2 is fitted on the outside. Further, the fixing portion 112 is brought into close contact with the fixing seat 116, and in this state, the fixing pin 1
By melting and deforming the tip of 18, the fixing portion 112 can be fixed to the fixing seat 116. Instead of the fixing pin 118, the pressing body 111 can be fixed by a screw or the like that is screwed and fixed to the fixing seat 116 through the through hole 117.

The fixing portion 112 of the pressing body 111 can be fixed more stably as the outer shape thereof is formed larger, and the elastic arm 114 can be elastically deformed more flexibly, but a space for fixing the fixing portion 112 is provided by that amount. It is necessary and the entire charger becomes large. However, as in the present embodiment, when the fixing portion 112 is fixed to the base frame 19 in a state where the drainage port 94 of the bottom wall 49 faces the flow path opening 115 of the fixing portion 112 formed in an endless ring shape, the fixing portion 112 Although the outer shape is enlarged, the central portion of the fixed portion 112, which is a dead space, can be used as a flow path through which drainage passes. Therefore, the entire charger can be made compact while allowing the elastic arm 114 to be elastically deformed flexibly.

The tip of the protrusion of each pressing portion 113 projects to the tray mounting portion 98 through the exposed hole 119 provided in the base frame 19, and the protruding portion of the pressing portion 113 is an engagement formed in the drainage tray 95. It is engaged with the recess 120. The engaging recess 120 is composed of a recess formed in the upper surface of the peripheral side wall 101 and the flange wall 103, and the drainage tray 95 is a tray mounting portion 98.
The pressing portion 113 is depressed and engaged with the engaging recess 120 in the state of being mounted on the engaging portion 113. In this way, when the engaging recess 120 in which the pressing portion 113 falls and engages is formed on the upper surface of the drainage tray 95 when the tray 95 is in the mounting position, the drainage tray 95 can be held in the mounting position. can. Further, in attaching / detaching the drainage tray 95, when the pressing portion 113 comes out of the engaging recess 120 at the start of the drawer separation and at the end of the insertion mounting, the pressing portion 113
The user feels a sense of operation of the drain tray 95 when the material falls into the engaging recess 120, so that 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 drainage tray 95 can be combined, there is an advantage that the number of parts can be reduced and the manufacturing cost can be reduced.

Two elastic arms 114 are extended from the fixed portion 112, and the tip of each elastic arm 114 is continuous with the end of the pressing portion 113 formed in the shape of a strip that curves downward toward the drain tray 95. Therefore, the fixing portion 112, the elastic arm 114, and the pressing portion 113 are formed in a frame shape. As a result, the structural strength of the pressing body 111 can be increased, and the elastic arm 114 can be elastically deformed more flexibly, so that an accurate position holding function and a clear moderation function can be exhibited. A pair of elastic arms 1 face the fixed portion 112 so as to face the fixed portion 112 with the fixed portion 112 in between.
Since a set of 14 and a pressing portion 113 are provided, the drain tray 95 is provided at two locations.
Can be pushed down and urged toward the rail wall 110, and the drainage tray 95 can be more reliably prevented from rattling in the vertical direction. It is also advantageous in that it can exert a more accurate position holding function and a clear moderation function.

The base frame 19 is provided with a drainage cylinder 96 that guides the water drained from the drainage port 94 to the drainage tray 95, and when the fixing portion 112 of the pressing body 111 is fixed to the drainage cylinder 96, the structural 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 more accurate position holding function and clear moderation function can be exhibited.
Further, when the fixing portion 112 of the pressing body 111 is fixed to the fixed seat 116 of the drainage cylinder 96 while the flow path opening 115 of the pressing body 111 is fitted onto the drainage cylinder 96, the fixing portion 112 is the cylinder of the drainage cylinder 96. Since the pressing body 111 is supported and fixed while being restricted from moving in the direction orthogonal to the axis, the pressing body 111 can be fixed more firmly.

The charger main body 18 is provided with a power socket 123 for receiving power to receive the drive power of the charger, and the connection plug 1 provided at one end of the power cord in the power socket 123.
24 are plugged in and connected. The power cord on the other end 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 body 18 is assumed in a plan view of the charger, the right side (one side) of the charger body 18 divided by the virtual line V is assumed. Tray opening 97 is placed in the area of
The power socket 123 is arranged in the area on the left side (the other side).

When the tray opening 97 is arranged in the area on the right side of the charger body 18 divided by the virtual line V as described above and the power socket 123 is arranged in the area on the left side, the tray opening 97 and the power socket 1 are arranged.
Even if water spills when the drain tray 95 is separated by keeping the distance from 23 as far as possible, the power socket 123 will not be splashed with water. Therefore, it is possible to effectively prevent short circuits and corrosion from occurring in the power socket 123. When assuming the above virtual line V and the second virtual line that passes through the center of the charger body 18 and is orthogonal to the virtual line V, the tray opening 97 and the power socket 123 are arranged in the diagonal quadrant region. You can also do it. In this case, both 97.1
By further moving the 23 away, it is possible to further suppress water from adhering to the power socket 123 when the drain tray 95 is attached or detached.

The connection plug 124 is plugged and connected to the power socket 123 from the rear to the front. As a result, 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 to be parallel to the mounting surface of the charger (horizontal direction). As described above, the attachment / detachment direction of the drainage tray 95 is orthogonal to the flow direction of the water flowing through the drainage port 94.
The drainage tray 95 is configured to be attached / detached, the connection plug 124 is inserted, and the drainage port 94 is configured to be orthogonal to each other.

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

The power socket 123 is provided in the inner inner part of the socket recess 125 formed in the charger main body 18. The socket recess 125 is formed by being recessed upward on the bottom surface of the base frame 19, and is open on the left surface, the rear surface, and the bottom surface of the charger main body 18. As shown in FIGS. 10 and 11, the inner wall surface forming the upper side and the right side of the socket recess 125 is a connection plug 12
It is formed in a constricted shape toward the inner back in the insertion direction of No. 4. Such socket recess 1
According to 25, the inlet side of the socket recess 125 can be widened and the inner inner portion can be narrowed.
As a result, at the initial stage of 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 the connection plug 124 and the charger body 18 can be easily inserted.
It is possible to prevent interference with the outer surface of the. Further, in the middle stage of connection of the connection plug 124, the connection plug 124 is guided by the wall surface and can be inserted so that the connection plug 124 approaches the socket recess 125, facilitating the connection of the connection plug 124 to the power socket 123. can. In this embodiment, both the upper and right inner wall surfaces are formed in a constricted shape toward the inner back in the insertion direction of the connection plug 124, but only one of the inner wall surfaces is constricted. It may be formed in a ball shape.

The mounting portion 21 is provided with a heating means that is driven together with the blowing means in the drying operation. 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 lower surface of the bottom wall 49, and a bottom wall 49 and a heater 12.

Reference numeral 8 denotes a sheathed heater having a circular cross section, which is provided in an annular shape around a horizontally long square frame-shaped heater base 130 fixed to a partition wall 28 of the base frame 19. The inner opening portion of the heater base 130 is arranged so as to face the translucent window 44 described above, whereby the heater 128 is arranged on the lower peripheral edge of the translucent window 44. Protective plate 129
Is formed in a square frame shape surrounding the periphery of the translucent window 44, 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 while heating the razor head 2 by driving the heating means and the blowing means, dry air is supplied and washed with water. Accelerates the drying of the razor head 2. However, the main blade 4 and the trimmer unit 5 provided in the cutting blade portion 3 have a precise 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 it will take time to dry. Therefore, in this embodiment, the bottom wall 49 is provided with a raised wall 133 facing the front surface 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 faces the front surface of the trimmer unit 5 in close contact with each other. The raised wall 133 can be provided so as to face the back surface of the cutting blade portion 3, and 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 facing the left and right side surfaces of the tip of the razor head 2 can also 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 body, and has a conductive plate 135 extending upward along the raised wall 133 and a heat receiving plate connected to the lower end of the conductive plate 135 to receive the heat of the heater 128. It is equipped with a plate 136. Conduction plate 13
Reference numeral 5 denotes a crank shape formed along the back surface of the raised wall 133, and is in close contact with the back surface of the raised wall 133. Insertion grooves 140 are provided on the upper surface of 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 in. The heat receiving plate 136 is in close contact with the upper surface of the front side of the protective plate 129, and the heat of the heater 128 is conducted to the heat transfer plate 134 through the protective plate 129. The conduction plate 135 may be provided on the back surface of the raised wall 133 in a state of facing each other with a slight gap.

As described above, if 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 highly flexible material can be held by the conductive plate 135, and the raised wall 133 can be cut by the cutting blade. It is possible to accurately face the front of the part 3. Further, the heat of the conduction plate 135 can be efficiently transferred to the raised wall 133. Therefore, the cutting blade portion 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 conduction 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. Therefore, the shape of the raised wall 133 can be held more accurately. There is also an advantage that the heat transfer loss between the two 133 and 135 can be reduced because the raised wall 133 and the conduction plate 135 are separated from each other.
Further, when the raised wall 133 is raised upward in a cross-sectional crank shape and the conduction plate 135 is formed in a shape along the back surface of the raised wall 133, the razor head 2 is mounted on the mounted portion 21 by inserting the electric razor into the raised wall 133. Since the crank-shaped cross section exhibits springiness even when it comes into contact with, it is possible to prevent the conductive plate 135 from buckling and deforming. When the raised wall 133 has a straight cross section, if the raised wall 133 is stretched and deformed so as to extend upward, the conducting plate 135 may come off from the insertion groove 140. However, in this embodiment, since the bent portion is formed in the middle portion of the conduction plate 135, only the raised wall 133 above the bent portion is stretched and deformed, so that the conduction plate 135 with a smaller elongation allowance is inserted. It is possible to prevent the groove 140 from coming off.

The heat transfer plate 134 is a plate fixing seat 1 formed on the partition wall 28 of the base frame 19.
It is fixed at 41. Specifically, a pair of left and right fixed tongue pieces 137 for fixing the protective plate 129 are provided at the tip of the heat receiving plate 136. A through hole 142 penetrating the plate surface is provided in the fixed tongue piece 137, and two fixing pins 143 are projected upward in the plate fixing seat 141.

Can be fixed. note that,
Instead of the fixing pin 143, the heat transfer plate 134 can be fixed by a screw or the like that is screwed and fixed to the plate fixing seat 141 via the through hole 142. When the heat transfer plate 134 is fixed to the plate fixing seat 141 of the base frame 19 in this way, the heat transfer plate 1
Since 34 can be firmly supported and fixed, the shape of the raised wall 133 can be held more accurately.

According to the electric razor charger provided with the above-mentioned heating means, by energizing the heater 128, the air in the mounting portion 21 is heated through the bottom wall 49 heated by the heater 128, and the razor is heated. The temperature of the entire head 2 can be raised to accelerate the drying of the razor head 2 after washing with water. 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 to effectively wash the razor head 2 with water. Drying can be promoted.
Also, if a metal protective plate 129 is provided between the bottom wall 49 and the heater 128,
Even if the electric razor falls on the bottom wall 49, the protective plate 129 can protect the heater 128. In addition, the heat receiving plate 136 of the heat transfer plate 134 is placed on the plate surface of the protective plate 129.
When they are brought into close contact with each other, the heat of the heater 128 is received by the heat receiving plate 13 via the metal protective plate 129.
It can be received at No. 6, and the decrease in heat conduction efficiency from the heater 128 to the heat transfer plate 134 due to the provision of the protective plate 129 can be almost eliminated.
In this embodiment, since a sheathed heater having a circular cross section is used for the heater 128, when the heater 128 is brought into direct contact with the bottom wall 49, both 49 and 128 come into contact with each other in a line contact manner. However, by interposing a metal protective plate 129 between the two 49 and 128, the heat of the heater 128 can be conducted to a wider range of bottom wall 49 through the protective plate 129, so that the bottom wall 49 can be provided. It can be heated efficiently.

In the above embodiment, the connection plug 124 on one end side of the power cord is connected to the power socket 123, the plug on the other end side of the power cord is connected to the outlet of the commercial power supply, and then the electric shaver in the inverted position is attached. The charger is configured so that the detection switch 55 is turned on and the charging operation for the electric shaver is automatically started by inserting it into the unit 21 and tilting it backward. In this way, instead of the operation mode of the charger in which the charging operation is automatically started when the detection switch 55 is switched to the ON state, the electric razor is mounted at an appropriate charging position of the mounting portion 21 and the detection switch. In a state where the 55 is switched to the on state, the charging operation can be started when the switch element 32 is manually pushed (on operation). Further, when the switch element 32 is pushed, the 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 sterilizing operations can be performed. In this operation mode, the three modes of standby, charging mode, and 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 operation mode, the charging operation is unnecessarily performed when the electric razor having a sufficient remaining charge of the secondary battery 13 is attached to the mounting portion 21 for storage. It is possible to suppress deterioration of the secondary battery 13 due to frequent repetition of a short-time charging operation. When the remaining charge of the secondary battery 13 is less than, for example, 40%, the charging operation may be started without pushing the switch element 32.

FIG. 14 shows a modified example of the power feeding terminal 71 in which the shape of the terminal portion 72 is changed. There, the terminal portion 72 has two peaks 80/80 and a valley 81 between the two peaks 80/80 by bending the plate portion continuous with the arm portion 74 into a corrugated plate shape by a pressing device. And the regulation part 85 is formed. The two mountain portions 80 and 80 are arranged in a direction along the engaging direction of the power receiving terminal 15.
According to such a power supply terminal 71, since it can be formed only by bending the blank material with a press device, the manufacturing cost of the power supply terminal 71 is reduced as compared with the power supply terminal 71 which is drawn to form the terminal portion 72. be able to. Further, it is not necessary to select a material having good drawability, and it is also advantageous in that the power supply terminal 71 can be formed with a cheaper material. By performing rib pressing on the tops of the peak 80 and the valley 81, the structural strength of the entire terminal 72 can be enhanced. Since the other parts are the same as those in the first embodiment, the same members are designated by the same reference numerals and the description thereof will be omitted. The same shall apply in the following description.

(Example 2) FIG. 15 shows Example 2 of a charger for a small electric device according to the present invention. This embodiment is different from the previous embodiment in that the detection switch 55 is arranged on the left wall surface 51 of the mounting portion 21 and both power supply terminals 71 and 71 are arranged on the right side surface 52. According to such an arrangement of the power supply terminal 71 and the detection switch 55, the position where the electric shaver is sandwiched by the urging force acting in the opposite direction by the urging member 77 of the power supply terminal 71 and the urging member 58 of the detection switch 55. It can be held, and it is possible to effectively prevent the electric shaver from shifting due to the urging force of each of the urging members 58 and 77 and the external force acting on the charger.

(Example 3) FIG. 16 shows Example 3 of a charger for a small electric device according to the present invention. This embodiment is different from the previous embodiment in that both power supply terminals 71 and 71 are arranged on the rear wall surface 50 of the mounting portion 21 and the detection switch 55 is arranged on the right side surface 52. According to the arrangement of the power supply terminal 71 and the detection switch 55, the electric razor can be pressed against the left wall surface 51 by the urging force of the urging member 58 of the detection switch 55 to hold the position, and the urging members 58 and 77 can be held. It is possible to effectively prevent the electric shaver from shifting due to the urging force generated by the electric shaver or the external force acting on the charger.

(Example 4) FIG. 17 shows Example 4 of a charger for a small electric device according to the present invention. In this embodiment, the support 147 that restricts the movement in the rear direction and the left-right direction while supporting the main body 1 of the electric shaver is formed separately from the charger main body 18. The support body 147 is composed of a pair of left and right support arms 148 and a support pillar 149 provided integrally with the pair of support arms 148, and is configured so that the support pillar 149 can be inserted and mounted on the charger body 18. There is. A power feeding terminal 71 is provided on each of the pair of support arms 148. According to such a charger, by separating the support 147 when not in use, the height dimension of the charger can be reduced, and the charger can be stored compactly. The base end portion of the support column 149 is rotatably supported by a rotating shaft provided on the charger body 18, and the support body 147 is housed in an upright posture capable of charging an electric shaver and a mounting portion 21. It is also possible to take a form in which the posture can be changed to the lying posture.

As described above, in the electric shaver charger of each of the above embodiments, the power supply terminal 71 and the detection switch 55 are arranged on the rear peripheral surface and the left and right peripheral surfaces of the inner peripheral surface surrounding the mounting portion 21.
The urging members 77 and 58 are used to advance and urge toward the peripheral surfaces of different electric razors in the mounted state. Therefore, the urging force of the urging members 77 and 58 can be applied to the peripheral surface of the electric razor from a plurality of directions. In the conventional charger, a large urging force acts on the same peripheral surface in the circumferential direction, and the electric razor may float away from the wall surface. However, in this embodiment, the electric razor is operated by different directions of the urging force. Can be prevented from floating off the wall surface. In addition, since a large urging force does not act on the same peripheral surface of the electric shaver,
It is not necessary to provide a holding structure to hold the position of the electric shaver as in the case of a conventional charger. As described above, according to the present embodiment, the electric shaver mounted on the mounting portion 21 can be held at an appropriate charging position without separately providing a structure dedicated to holding the position, so that the manufacturing cost can be suppressed and the electric shaver can be stably held. It is possible to provide a charger that performs a charging operation on an electric shaver.

In each of the above embodiments, the functions of the drying operation and the sterilizing operation are added to the charger (functional device) that performs the charging operation for the small electric device (electric razor). It can be seen as adding the functions of charging operation and / or sterilizing operation to the dryer (functional device) that performs the drying operation on the device.
