The present invention relates to a shaver cleaner for cleaning off hair and skin tissues adhered to the blade edge of a shaver, and a shaver system comprising the aforementioned shaver cleaner in conjunction with the shaver.
A shaver cleaner such as described above is shown in for example Patent Documents 1 and 2. In those conventional arts, there is proposed a cleaner which performs cleaning of the aforementioned blade edge by continuously supplying a cleaning liquid which is filtered by a filter, and thereafter performs drying as well. As a result of using such a cleaner, although shavers used to be stored near a water section such as a washroom to perform washing with water, it is made possible to store the shaver at any place such as a living room and a bed room, away from the water section, thereby improving convenience.
In the aforementioned conventional arts, the freedom of the installation location has been increased. However, for example, a wash stand is provided with shelves for placing beauty products such as a shaver and also with receptacles for supplying power, and therefore is suitable as the storage location for the aforementioned cleaner and shaver. Thus, when the storage location is changed, new problems may arise. For example, if there is no receptacle nearby, an extension cable is needed, and power supply wiring may be displeasing in appearance. Further, there is a risk of tripping over the power supply wiring and thereby overturning the whole cleaner. As a result, not only the equipment may be damaged, but also the cleaning liquid may be scattered.

It is an object of the invention to provide a shaver cleaner and shaver system, which enables to eliminate the troublesomeness due to power supply wiring, thereby further enhancing the convenience.
The shaver cleaner of the present invention comprises a fuel cell, which supplies power at least to a cleaning part for cleaning the shaver, and the heat from which is directed to a drying part for drying the shaver after cleaning. The shaver system of the present invention comprises this shaver cleaner.
Since the shaver cleaner and shaver system as configured above comprises a fuel cell thereby eliminating the need of power supply wiring, it becomes possible to eliminate the troublesomeness due to the power supply wiring and to further enhance its convenience. Further, since the heat from the fuel cell is used for drying the shaver after cleaning, it becomes possible to increase the energy utilization efficiency in the fuel cell.
Hereinafter, embodiments relating to the present invention will be described with reference to the drawings. It is noted that like configurations are given like symbols in each figure, and description thereof will be omitted.
The cleaner 2 is an apparatus which, when the shaver 1 is mounted onto a cleaning pan 21 which is a predetermined mounting location, can clean and dry a blade edge 11 of the shaver 1 and thereafter charge a built-in battery 12.
In the bottom part of the cleaner 2, a cartridge 23 which retains ethanol 22 as the cleaning liquid is installed. The ethanol 22 in the cartridge 23 is sucked up through a conduit 24 by a pump 25, and supplied to the cleaning pan 21 so that the blade edge 11 can be cleaned while being soaked in the ethanol 22. While being cleaned, the blade edge 11 of the shaver 1 may be appropriately vibrated. After cleaning is finished, the ethanol 22 is dropped into the cartridge 23 through a conduit 27 as a result of a valve 26 being opened. The bottom face of the cleaning pan 21 is sloped toward an intake port of the conduit 27. Beard debris is deposited into the bottom part of the cartridge 23. In view of preventing the deposited beard debris from being captured, the conduit 24 is arranged such that a suction port in the conduit 24 is spaced apart by a predetermined distance from the bottom face of the cartridge 23. As a result of this, as described below, it becomes easy to use the ethanol 22, which is the cleaning liquid, as the fuel. After cleaning is finished, a blower 28 is driven to dry the blade edge 11.
It should be noted in the present embodiment that the cleaner 2 comprises a fuel cell 51, which generates power to be used by the cleaner 2, and waste heat produced as the result of the power generation by the fuel cell 51 is conducted to the cleaning pan 21 through a heat pipe 30 and is used for heating the blade edge 11. Therefore, in the present embodiment, the cleaning pan 21, the pump 25, and the like constitute a cleaning part, the cleaning pan 21, the blower 28, and the like constitute a drying part, and the heat pipe 30 constitutes a heat transfer part. The aforementioned heat pipe 30 is placed in a meandering manner on the back side of the cleaning pan 21, which is made of a material of high heat conductivity such as aluminum, to improve heat propagation.
The aforementioned fuel cell 51 is made up of an electrolytic membrane 54 sandwiched by a cathode 52 and an anode 53. This fuel cell 51 uses ethanol 22 similar to the cleaning liquid as fuel. The fuel cell 51 generates power by causing the ethanol 22, which is sucked up from the cartridge 23 through a conduit 32 and a filter 33 for removing bead debris by driving a pump 31, to react with the oxygen in the air. As a result of power generation, air (oxygen) is taken in and water is discharged at the cathode 52 side. This water is once absorbed into absorbing means such as cloth (not shown) and thereafter dissipated into the air. Also, as a result of the power generation, the ethanol 22 is taken in and carbon dioxide is discharged at the anode 53 side. The generated power is supplied to the circuit block 41, and then supplied as the power source to the pumps 25 and 31, the valve 26, the blower 28, and the microcomputer to drive and control them, as well as the shaver 1.
The aforementioned high side input terminal T11 is connected from a power supply line 42 to a high-side output terminal T21 via a choke coil L1 and 2-stage cascade-connected diodes D1 and D2. The aforementioned low-side input terminal T12 is connected to a low-side output terminal T22 through a power supply line 43. Between the output terminals T21 and T22, a secondary battery 44 is connected which accumulates and smoothes energy to output it. From the output terminals T21 and T22, power is supplied to the pumps 25, 31, the valve 26, the blower 28 and the microcomputer not shown as well as the shaver 1.
It is noted that if the shaver 1 and other loads share the secondary battery 44, the electric charge on the secondary battery 44 may be fully drained due to charging, and thus there may be an adverse effect on the next activation. If that is the case, a separate secondary battery may be provided by separating it with a diode, etc. Further, if the operable voltage of other load equipment is lower than the charging voltage of the shaver 1, it becomes possible to activate other load equipment by the secondary battery 44, even in a stage that the power generation of fuel cell 51 is finished and the charging to shaver 1 is finished. Further, by configuring such that the cartridge 23 is installed above the fuel cell 51 so that the ethanol 22 is manually caused to flow into the fuel cell 51 upon activation, it becomes possible to activate other load equipment by the fuel cell 51 without fail.
An FET 45 is interposed between the connecting point of a choke coil L1 and a diode D1, and a low-side power supply line 43. This FET 45 is ON/OFF driven by a PWM control circuit 46 through an activation resistance R1. The aforementioned PWM control circuit 46 is driven by the output voltage of the secondary battery 44. The aforementioned PWM control circuit 46 divides and takes in the voltage between the connecting point of the diodes D1 and D2 and the low-side power supply line 43 with resistors R1, R2 and controls the gate of the FET 45. Specifically, the PWM control circuit 46 turns the FET 45 ON with the gate of the FET 45 being brought to a high-level. As a result of this, energy from the fuel cell 51 is accumulated in the choke coil L1. Then, the PWM control circuit 46 causes the energy accumulated in the choke coil L1 to be released to the secondary battery 44 through the diodes D1 and D2 when turning the FET 45 OFF with the gate of the FET 44 being brought to a low level. The PWM control circuit 46 reads the peak voltage during that release via the resistors R2 and R3, and controls the ON duty of the FET 45 such that the peak voltage becomes a predetermined value. The circuit block shown in
Thus, the circuit block shown in
As so far described, in the shaver system S of the present embodiment, since the fuel cell 51 is provided as the power supply and the power thereof is used to drive the arrangement including at least the pump 25 and the valve 26 as well as the microcomputer for performing the cleaning, it becomes possible to eliminate the need of power supply wiring for the cleaner 2, thereby enabling to expand the selection range of the storage place of the shaver 1. As a result of this, the troublesomeness due to the power supply wiring is eliminated, thereby enabling to further improve convenience. Further, by using the wasted heat by the fuel cell 51 for the drying of blade edge 11, it is possible to increase the energy utilization efficiency of the fuel cell 51.
Further, using a heat pipe 30 in the heat transfer part form the fuel cell 51 to the blade edge 11 will enable to guide the wasted heat of the fuel cell 51 to the blade edge 11 in an effective manner. Further, since the fuel cell 51 utilizes the ethanol 22 similar to the cleaning liquid as a fuel, the number of kinds of consumable stores will not increase, and the replenishment thereof can be carried out at one time, it is possible to enhance the ease-of-use and to reduce the cost of the consumable stores (fuel and cleaning liquid).
Further, using ethanol 22 as the fuel and the cleaning liquid is advantageous in that its toxicity is lower than that of methyl alcohol and its acquisition becomes easier. Furthermore, ethanol has a larger calorific value and therefore is more suitable for the drying described above. In addition, while direct reaction of hydrogen and oxygen may pose a risk of explosion, using alcohol enables to increase the level of safety. Further, although the reaction of alcohol and oxygen is less effective than that of hydrogen and oxygen and produces a large amount of heat, by using that heat as the heat source during drying as described above, it is possible to increase the overall heat efficiency of the fuel cell 51 even though alcohol is used.

A series circuit of a primary winding N1 of a transformer 62, the FET 45, and a current detection resistor R11 is connected between power supply lines 42 and 43 extending from the input terminals T11 and T12. A resonance capacitor C11 is connected in parallel to the primary winding N1. Further, a series circuit of an activation resistor R12 and a capacitor C12 is connected between the power supply lines 42 and 43, and connecting point thereof is connected to the gate of the FET 45 through an auxiliary winding N3 of the transformer 62 and a bias resistor R13. A control transistor TR is connected between the gate of the FET 45 and the low-side power supply line 43, and its base is connected through a resistor R14 to the connecting point of the FET 45 and the current detection resistor R11.
In the shaver 1a, a series circuit of a diode D11 and a capacitor C13 is connected to the both ends of the secondary winding N2 of the transformer 62. A built-in battery 12 is connected in parallel to the capacitor C13.
Therefore, the capacitor C12 is charged at a constant voltage by the current from the fuel cell 51 or the AC adaptor 61 through the activation resistor R12. When the gate of the FET 45 is turned to a high level by the charge voltage of the capacitor C12 through the auxiliary winding N3 and the bias resistor R13, and thereby the FET 45 is turned ON, the capacitor C11 causes the voltage between the terminals of the primary winding N1 to rise slowly and excitation energy is accumulated in the primary winding N1. The gate of the FET 45 is forwardly biased by the voltage induced by the auxiliary winding N3 of the transformer 62, and which is self-held. When the current flowing in the primary winding N1 becomes more than a predetermined value as a result of the FET 45 being turned ON, the control transistor TR is turned ON by the voltage across the terminals of the current detection resistor R11. As a result of this, the gate of the FET 45 is brought into a low level causing the FET 45 to go OFF; and the energy accumulated in the primary winding N1 is released from the secondary winding N2 and is rectified and smoothed by the diode D11 and the capacitor C13, thereby causing the built-in battery 12 to be charged.
Thus, in the configuration in which the shave 1a is charged by being boosted using the transformer 62 by the switching of the FET 45, as shown in
Further, since it is also made possible to supply power as needed from the detachable AC adaptor 61 to the cleaner 2a through the power receiving terminals T31 and T32, the charging of the shaver 1a can be carried out even when the fuel of the fuel cell 51, such as the ethanol 22 runs out. Also, when not necessary, the AC adaptor 61 may be detached so that the troublesomeness due to the power supply wiring will not become a problem. Further, when cleaning is performed by the power from the AC adaptor 61, the cartridge 23 is configured such that the space for retaining the ethanol 22 is divided into two sections: one for fuel and one for cleaning so that as the section for fuel is emptied, water is retained in the section for cleaning, thereby making it possible to perform cleaning with water without affecting the fuel cell 51. Furthermore, the cleaner 2a may be configured by the microcomputer etc. such that when water is retained in the entire cartridge 23, the pump 31 will not be driven.

Further, it is noticeable in the present embodiment that a heater 71 is provided on the back side of the cleaning pan 21. The heater 71 constitutes a heating part, and is adapted to heat the blade edge 11 through induction heating, resistance heating, and the like (
Furthermore, it is noticeable in the present embodiment that a flow meter 72 is provided in the path for suction of fuel ethanol 22 by the pump 31 so that the injection rate of the ethanol 22 is regulated to adjust the amount of power generation.
In
The output from the flow meter 72 is inputted to the microcomputer 73. The microcomputer 73 drives a pump 31 by outputting a control signal to the pump 31 until the flow rate to be inputted becomes a necessary amount for the power generation of this time. In this respect, when cleaning, drying and charging are performed in a series of operations, the pump 31 may continuously driven so that a necessary amount of ethanol 22 is lifted up in a lump-sum to a reservoir tank (not shown) and this lifted ethanol 22 is slowly supplied by gravity-drop to the fuel cell 51. Alternatively, the pump 31 may be driven intermittently and controlled such that the amount to be consumed at the fuel cell 51 is successively replenished and the total of the replenishment amount will be the necessary amount for the power generation of this time as mentioned before. It is noted that all of the ethanol 22 supplied reacts with oxygen to be used for power generation, and an excess amount of power is charged to the secondary cell 44.
Further, the microcomputer 73 communicates with the shaver 1 through a communication path not shown and when the shaver 1 becomes fully charged within a relatively short time, the microcomputer 73 turns the FET 74 ON through the resistor R4 to drive the heater 71 to make up the shortfall of the amount of heat from the fuel cell 51 for drying the blade edge 11. While driving of such load is required, the microcomputer 73 drives the PWM control circuit 46 to oscillate for boosting.
