Description

  The present invention relates to a cleaning device for cleaning a hair removal tool such as an electric razor or a hair removal device.

  Conventionally, as a cleaning device for cleaning a hair removal device such as an electric razor or a hair removal device, a cleaning tank for positioning a hair processing unit of the hair removal device is provided, and the cleaning liquid in the tank is circulated in the cleaning tank. In order to clean the body hair treatment part, it has been proposed (see Patent Document 1). This is a structure in which a tank containing a cleaning liquid is disposed below the cleaning tank, and the cleaning liquid in the tank is fed to the cleaning tank using a pump, and the hair treatment unit is cleaned in the cleaning tank. Later, the cleaning liquid in the cleaning tank is naturally dropped by its own weight and recovered in the tank. Here, in the above-described conventional cleaning apparatus, since the tank is positioned below the cleaning tank, there is a problem that the entire cleaning apparatus is tall and therefore inconvenient to store.

  In order to solve this problem, an airtight internal space is formed in the tank, and a valve portion that opens the internal space to the atmosphere is provided. Gas and gas are introduced into a circulation channel that connects the cleaning tank and the tank. It can be considered to have a structure in which a pump unit capable of feeding is arranged. In the above structure, by first feeding the gas toward the internal space in the airtight state in the tank, it is possible to overflow the cleaning liquid in the tank into the cleaning tank due to the pressure increase. It is possible to circulate the cleaning liquid between the cleaning tank and the tank after a certain amount of cleaning liquid is stored in the tank, and to open the airtight internal space to the atmosphere and then toward the internal space. It is possible to collect the cleaning liquid in the tank by feeding the cleaning liquid in the cleaning tank. That is, with the above structure, the cleaning liquid can be circulated without any problem without positioning the tank below the cleaning tank, and it is only necessary to have one pump unit as a driving source, so that the height is short and compact. It is provided as a cleaning device.

However, in the cleaning device having the above structure, when a fouling is clogged in the filter interposed in the circulation flow path, a sufficient amount of gas or liquid cannot be fed through the pump unit. Therefore, there is a problem that sufficient cleaning liquid is not supplied to the cleaning tank. To solve the above problem, it is sufficient to replace the filter every predetermined period to ensure good air permeability. In this case, the user constantly grasps the elapsed time since the last replacement. There arises a problem that it is necessary to keep it, and a problem that the replacement time is not always an appropriate replacement time for the filter when it is replaced every predetermined period.
JP-A-7-236514

  The present invention has been invented in view of the above problems, and is short and compact, and the user can easily and surely determine the replacement time of the filter, and always performs a good cleaning operation. An object of the present invention is to provide a cleaning device for a hair removal tool that can be performed.

  In order to solve the above-described problems, the cleaning device 1 for the hair removal device 9 according to the present invention stores the cleaning tank 11 in which the hair processing unit 90 of the hair removal device 9 for removing hair is disposed, and the cleaning liquid The tank 3, the valve portion 105 that opens the airtight internal space of the tank 3, the circulation passage 15 that connects the cleaning tank 11 and the tank 3, and the circulation passage 15. The gas and liquid are fed toward the internal space in the tank 3 which is in an airtight state, whereby the cleaning liquid in the tank 3 is circulated between the tank 11 and the valve 105 is opened to the atmosphere. The pump unit 6 that collects the cleaning liquid in the tank 3 by feeding the cleaning liquid in the cleaning tank 11 toward the internal space and the filter 41 that captures the dirt of the cleaning liquid in the circulation channel 15 are provided. , The filter 41 As detection means for detecting the replacement timing, and those with liquid level detection unit 16 for detecting the liquid level of the cleaning liquid which is accumulated in the cleaning tank 11.

  In the cleaning apparatus 1 having the above-described configuration, the cleaning liquid can be circulated between the tank 3 and the cleaning tank 11 without the tank 3 being positioned below the cleaning tank 11. Since only one pump unit 6 capable of feeding gas and liquid can be provided in the internal space, it is provided as a short and compact cleaning device. When the filter 41 is clogged with hairs and a sufficient amount of gas or liquid cannot be fed to the tank 3, the cleaning liquid cannot be stored in the cleaning tank 11 to a sufficient liquid level. This can be detected by the liquid level detection unit 16 and can be notified that it is time to replace the filter 41. Therefore, it is possible for the user to easily and reliably determine the replacement time of the filter 41, and always A good cleaning operation can be performed.

  The present invention is short and compact, and the user can easily and surely determine the replacement time of the filter, and can always perform a good cleaning operation.

  As shown in FIG. 15, the washing tank 11 fixed on the base 10 and housed in the opening 141 in the upper cover 14 has a waterproof rubber 114 fixed to the periphery of the lower surface thereof by a fixing frame 115 and an upper front portion. Further, a drying fan 5 comprising an axial fan is attached to the tank 110 via a fan guard 50, and a support rubber 119 and the like for receiving the liquid level detection pin 128 and the hair processing unit 90 of the hair removal device 9 are disposed in the tank 110. In this case, an inlet 111 is provided at the rear portion on one side, and an overflow outlet 117 shown in FIG. 3 and an outlet 118 opened at the bottom are further provided. Reference numeral 116 in FIG. 15 denotes a protective rubber attached to the fan guard 50 portion.

  As described above, the connection stand portion 2 is held by the rising portion 102 of the base 10 so as to be slidable up and down and protrudes upward from the opening 142 of the upper cover 14. As shown in FIG. The terminal 21 is held in the upper end portion of the slidable member and the slide block 23 is slidable back and forth, and the lower part is click-positioned at both end positions of the slidable stroke. A leaf spring 27 having a click projection 28 is incorporated.

  The terminal 21 has a shaft hole 211 positioned at the rear portion thereof and is supported by the shaft 200 of the housing 20 so that the front end side thereof is turned up and down, and includes a plurality of contact plates 22. These contact plates 22 are connected to the charging circuit on the circuit board 75 through lead wires 220.

  The slide block 23 that is slidable in the front-rear direction includes main body detection switches 26 and 260, a lock button 24, and a return spring 25. The lock button 24 has a front end of a concave surface at the front end of the slide block 23. It protrudes forward from the center. The slide block 23 is engaged with a cam portion 210 provided on the terminal 21. When the slide block 23 protrudes forward due to the biasing force of the return spring 25, the front end portion of the terminal 21 is moved upward. If the slide block 23 is slid rearward, the front end portion of the terminal 21 is rotated downward.

  The slide block 23 does not move backward when the lock button 24 is pushed in and the lock is not released, and the slide block 23 is slid as described above so that the lock button 24 is not pushed inadvertently. The front end surface of the block 23 is a concave surface so that the front end of the lock button 24 does not protrude beyond the front end of the slide block 23.

  As shown in FIG. 19, the tank 3 for storing a solvent mainly composed of water (or alcohol) as a cleaning liquid is such that the bottom opening of the tank body 30 is closed by a bottom plate 31, and the opening 300 to which the cap 35 is attached. Is provided at the upper end surface, the discharge port 34 is provided on one side of the upper front surface, and the inlet 32 and the ventilation port 33 are provided on the other side, and the internal space is divided into two. The opening 300, the inlet 32 and the vent 33 are located in one of the pressurizing compartments, and the discharge outlet 34 is located in the other open compartment. Sometimes they communicate with each other where they are below the liquid level. Further, the open section on the discharge port 34 side has a considerably small internal volume due to the protrusion 36 rising from the bottom plate 31.

  When the tank 3 is mounted on the mounting portion 103 of the base 10, the inlet 32 is connected to the outlet 6b of the pump unit 6 via the connection port 106 of the base 10 and the tube 107 (see FIG. 19). The vent 33 located above the inlet 32 is connected to the valve portion 105 of the base 10, and the discharge port 34 is connected to the discharge pipe 108. The discharge pipe 108 has an upper end opened to the atmosphere and a lower end located in the introduction port 111 in the cleaning tank 11.

  The cap 35 disposed at the upper end of the tank 3 also functions as a valve that opens and closes the communication between the pressurization compartment and the atmosphere. When the cap 35 is not attached to the base 10, the opening 300 is not completely closed. When the tank 3 is fixed by the knob 7 that is attached to the base 10 and is slidably and rotatably held on the base 10, the cap 35 is pressed down to completely close the opening 300. Reference numeral 70 shown in FIG. 16 denotes a shaft that connects the knob 7 to the base 10 so as to be slidable and rotatable.

  As shown in FIGS. 13 and 20, the solute case 4 is a case 40 in which a filter 41 containing a solute is contained in a case 40 having a lid 42 having an opening at the center. It can be attached and detached by sliding back and forth with respect to the mounting portion 104 of the base 10. When mounted on the base 10, the upper peripheral portion comes into contact with the waterproof rubber 114 disposed around the lower surface of the cleaning tank 11, and the space between the cleaning tank 11 including the overflow discharge port 117 and the discharge port 118 and the solute case 4 is watertight. Held in a state. Further, when the base 10 is mounted, the connection port 44 is connected to the suction port 6 a in the pump unit 6. Reference numeral 43 in FIG. 20 denotes a laminate seal that closes the opening of the lid 42 of the solute case 4 and is peeled off when the solute case 4 is set in the cleaning device 1.

  That is, the circulation flow path 15 schematically shown in FIG. 1 is formed by the overflow discharge port 17 and the discharge port 18, the solute case 4, the pump unit 6, the tube 107, the discharge pipe 108, and the like. Are connected to each other so that the cleaning liquid can be circulated between them, and the pump unit 6 located in the flow path feeds gas and liquid toward the tank 3.

  Now, with the tank 3 containing the solvent as the cleaning liquid and the solute case 4 set and the connection stand portion 2 pulled up, the power is turned on as shown in the flowchart of FIG. When the hair processing unit 90 is fitted in the tank 110 of the cleaning tank 11 and the slide block 23 of the connection stand unit 2 is pushed backward by the hair removal device 9, the lock button 24 is first pushed by the hair removal device 9 and the slide block 23. When the slide block 23 is pushed rearward with the hair removal device 9, the terminal 21 engaging the cam portion 210 with the slide block 23 rotates, and the front end of the terminal 21 is moved. By moving downward and fitting into the hair removal device 9, the hair removal device 9 is fixed, and at the same time, the contact plate 22 in the terminal 21 is removed from the hair removal device. 9 is connected to the charging connection terminals, charging is started to the secondary battery in the hair removing apparatus 9.

  When the switch button 17 disposed on the upper cover 14 is pressed in a state where the fixing of the hair removal tool 9 is detected, the solenoid 8 is activated and the rod 80 provided with the on-off valve 81 is pulled down. The valve portion 105 communicating with the third vent 33 is closed. At this time, since the cap 35 of the tank 3 completely closes the opening 300 by the knob 7 described above, the pressure section connected to the pump unit 6 in the tank 3 is in an airtight state. For this purpose, the pump unit 6 that has been operated when the switch button 17 is turned on first sucks air from the solute case 4 side and sends it to the pressurizing section of the tank 3, which increases the pressure in the pressurizing section. Press down on the surface of the cleaning solution. Along with this, the liquid level on the open section side in the tank 3 rises, and when the liquid level rises to the position of the discharge port 34, the cleaning liquid is sent into the cleaning tank 11 through the discharge pipe 108. At this time, since the internal volume of the open section is considerably reduced by the protrusion 36 rising from the bottom plate 31 in the tank 3, the cleaning liquid overflows to the cleaning tank 11 side even if the pressure value of the pressurizing section is not so high. To do.

  The opening area of the discharge port 118 formed at the bottom of the cleaning tank 11 is set to be small, and the amount of cleaning liquid fed into the cleaning tank 11 is larger than the amount of cleaning liquid flowing out of the tank 110 through this. When the cleaning tank 11 is filled, and the liquid level reaches the liquid level detection pin 128, power is directly supplied to the built-in motor of the hair removal tool 9 through the terminal 21 and immersed in the cleaning liquid. The activated hair processing unit 90 is operated. The liquid level detection pin 128 detects that the cleaning liquid is in a state of filling the cleaning tank 11. If the liquid level of the cleaning liquid is positioned slightly above the point below the overflow discharge port 117, the liquid level detection pin 128 detects the liquid level. It is installed in the cleaning tank 11 so as to detect the surface.

  Then, the cleaning liquid in the cleaning tank 11 flows into the solute case 4 through the overflow outlet 117 and the outlet 118, is filtered while passing through the filter 41, dissolves the solute, and is then sucked into the pump unit 6. . Thereafter, a solution in which a solute is dissolved in a solvent circulates between the tank 3 and the washing tank 11 as a washing liquid, and dirt such as fuzz washed away from the body hair treatment unit 90 is removed from the circulation channel 15. It is captured by the filter 41 in the solute case 4 interposed inside.

  The filter 41 is formed of a cotton-like material and is formed of three upper and lower layers, and the lower layer is finer. This is because the dirt washed away from the hair processing unit 90, in particular, the hair chips can be dispersed and captured so that a large amount of hair chips can be captured. The solute filled in the solute case 4 while being held by the filter 41 includes at least one, preferably all, of a surfactant, a disinfectant, an antifoaming agent, and a lubricant. A thing can be used suitably. The surfactant can improve the cleaning effect, the bactericidal agent can eliminate the smell of sebum and keep it clean, the antifoaming agent suppresses the generation of bubbles and enhances the cleaning effect and after cleaning The time required for drying the hair can be shortened, and the frictional resistance of the movable part of the body hair treatment unit 90 can be reduced by the lubricant.

  When the cleaning operation for a predetermined time is finished, the valve unit 105 is opened by stopping the motor of the hair removal tool 9 and returning the solenoid 8. At this time, the pressurization section is opened to the atmosphere, and the liquid level of the cleaning liquid in the pressurization section rises and the liquid level in the open section decreases, so the supply of the cleaning liquid to the cleaning tank 11 is stopped. However, the pump unit 6 continuously supplies the cleaning liquid to the tank 3 after that, and recovers the cleaning liquid in the cleaning tank 11 to the tank 3 side.

  When the cleaning liquid is exhausted from the cleaning tank 11, the fan 5 operates for a predetermined time and blows air sucked through the louver part 145 of the upper cover 14 onto the body hair processing part 90, thereby promoting drying of the body hair processing part 90.

  Removal of the hair removal tool 9 from the cleaning device 1 is performed by pulling the upper part of the hair removal tool 9 forward. By this operation, the terminal 21 of the connection stand part 2 is rotated and disengaged from the hair removal tool 9, and the slide block 23 interlocked with the terminal 21 is also advanced. And after extracting the hair removal tool 9, if it has the terminal 21 which will hold down the hair removal tool 9 from the upper part if the connection stand part 2 is pushed down, the state where the vertical height is small Can be held in. After removal of the hair removal device 9, the standby state is maintained until the hair removal device 9 is set again.

  By the way, in this washing | cleaning apparatus 1, a pressurization division of the internal space of the tank 3 is pressurized, a washing | cleaning liquid is supplied to the washing tank 11, and the pump unit 6 is operated in the state which opened the said pressure division of the internal space. Thus, since the cleaning liquid in the cleaning tank 11 is collected on the tank 3 side, there is no problem even if the liquid level in the tank 3 is located above the cleaning tank 11. Even if the tank 3 is used, the short cleaning apparatus 1 can be obtained.

  When the solute in the solute case 4 runs out or when the filter 41 captures a lot of dirt and becomes clogged, the solute case 4 may be replaced. In particular, when the filter 41 is clogged with fluff or the like, a sufficient amount of gas or liquid cannot be supplied to the pressurized section of the tank 3 even if the pump unit 6 is driven. A sufficient amount of cleaning liquid will not be supplied to the tank 11. On the other hand, in this example, the liquid level detection pin 128 for detecting whether or not the liquid level of the cleaning liquid stored in the cleaning tank 11 is in a state satisfying the cleaning tank 11 is provided on the filter 41. Since it is also used as the liquid level detection unit 16 for detecting the replacement time (see FIG. 1), the user can easily and reliably confirm that the filter 41, that is, the solute case 4 is at the replacement time through the liquid level detection pin 128. It is possible to judge.

  Specifically, the liquid level is cleaned via the liquid level detection pin 128 when a predetermined time or more has passed since the pump unit 6 began to feed gas to supply the cleaning liquid in the tank 3 to the cleaning tank 11. If it is detected that the tank 11 is not in a filled state, it is determined that the filter 41 is in a clogged state as shown in FIG. 2, and a filter replacement display (not shown) is turned on. Whether or not the solute case 4 has been replaced is periodically confirmed by interrupt processing through the contact plates 77 and 78, and when the replacement of the solute case 4 is confirmed, the filter replacement display is turned off. In this example, the pump unit 6 is set not to operate if the filter replacement display remains on, and the cleaning operation is not started again. To force.

  The liquid level detection unit 16 is not limited to the liquid level detection pin 128. For example, a float switch that detects the liquid level of the cleaning liquid, or the liquid level of the cleaning liquid by measuring capacitance is used. It is possible to turn on the filter replacement display based on the same determination by providing a capacitance measuring unit for detecting the thickness and using this as the liquid level detecting unit 16. In addition, the liquid level detector 16 does not detect the liquid level of the cleaning liquid as described above, but includes a flow meter for detecting the flow rate in the circulation flow path 15 and the cleaning liquid being circulated by the flow meter. The filter replacement display may be turned on when it is determined that the flow rate has decreased, or the filter replacement display may be turned on when it is determined that the pump current of the pump unit 6 has increased. May be.
