  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiment. A cleaning device 1 in the illustrated example is for cleaning a blade head portion Ea of a small electric device E that is a reciprocating electric shaver. An opening 20 for inserting the blade head Ea in an inverted state is provided on the upper surface.

  As shown in FIGS. 3, 5, and 6, the cleaning apparatus 1 includes a cleaning dish 5, a container 7 that stores cleaning liquid therein, and a pump P that circulates the cleaning liquid between the container 7 and the cleaning dish 5. And a support unit S including a heater unit H and a motor fan F for drying the cleaned blade head part Ea, and further including a connection part for electrical connection with the small electrical device E on the upper rear side. have.

  The container 7 containing the cleaning liquid is set in the cleaning device 1, and the blade head portion Ea of the small electric device E is positioned in the cleaning dish 5 through the opening 20, and at the same time, the small electric device is connected at the connection portion of the support portion S. When E and the cleaning apparatus 1 are electrically connected and the pump P is operated in this state, the pump P supplies the cleaning liquid in the container 7 into the cleaning dish 5. The cleaning liquid that has passed through the overflow weir 54 provided in the cleaning dish 5 returns to the container 7 located below the cleaning dish 5. During the cleaning, by operating the blade head portion Ea in the small electric device E by power feeding and signal transmission through the connecting portion, the blade head portion Ea can be cleaned more quickly and effectively.

  Next, each part will be described in detail with reference to FIGS. 5 and 6. The cleaning apparatus 1 includes a bottom plate 11, a base substrate 12 that can move up and down with respect to the bottom plate 11, and a support frame 13 installed on the base substrate 12. The upper edge of the support frame 13 is supported by the upper edge of the four circumferences, the top cover 2 having the opening 20, the support base 6 to which the connecting portion is attached, the side cover 15 covering the side surface, and the front surface. The front cover 16 is arranged.

  The bottom plate 11 is provided with guide columns 110, 110 standing upright from both the left and right sides, and the base substrate 12 is movable up and down along the guide columns 110. Further, the base substrate 12 is urged upward by a push-up bar 111 having a spring 112 disposed in the guide column 110 of the bottom plate 11.

  A switch plate 31 is arranged on the base substrate 12 so as to be slidable left and right. The switch plate 31 urged in one direction by the spring 32 and having one end exposed to the outside from the side cover 15 has an engaging portion with a hook portion 115 formed at the upper end of the guide column 110. When the switch plate 31 is pushed in against the bias of the spring 32, the base substrate 12 moves upward under the bias of the spring 112 because the engagement with the hook portion 115 is released. If the base substrate 12 is pushed downward, the switch plate 31 is re-engaged with the hook portion 115, so that the base substrate 12 is held in the depressed state.

  The base substrate 12 includes a cylindrical motor cover portion 120 protruding downward, and the motor M is accommodated in the motor cover portion 120 via a motor case 121. As shown in FIG. 11, an impeller 123 is attached to the motor output shaft that protrudes downward from the bottom surface of the motor cover portion 120 through the M-shaped seal 122, and the periphery of the impeller 123 is at the center of the bottom portion. A pump cover 124 having an inlet opening is attached. When the impeller 123 rotates, the cleaning liquid sucked from the suction port of the pump cover 124 is sent to a later-described supply / drain port 56 of the cleaning dish 5 through a supply pipe 126 provided integrally with the motor cover unit 120.

  Three water level detection pins 24, 25, and 26 are arranged on the outer peripheral side of the motor cover portion 120. These three water level detection pins 24, 25 and 26 to be immersed in the cleaning liquid in the container 7 detect the water level of the cleaning liquid based on the electric resistance value between them. In other words, since the cleaning liquid has conductivity, the water level is detected by utilizing the fact that the electrical resistance value is larger than a predetermined value when there is no cleaning liquid between the water level detection pins 24 and 25 and between the water level detection pins 24 and 26. To do.

  Here, among the water level detection pins 24, 25 and 26, the lower end position of the water level detection pin 24 is the lowest, and the lower end positions of the water level detection pins 25 and 26 are also different in height. For example, it is possible to detect when the remaining amount of the cleaning liquid has decreased and when it has become less than the amount necessary for circulating the cleaning liquid to perform the cleaning operation (when cleaning cannot be performed). The reason why the lower end of the water level detection pin 24 is positioned lower than the other two water level detection pins 25 and 26 is to provide a detection margin when the cleaning device 1 is installed on an inclined surface. .

  A cleaning dish 5 is disposed on the base substrate 12 via a support frame 13. The washing dish 5 formed of a soft material such as rubber includes a folded portion 50 that protrudes from the upper edge to the outer peripheral side and has its tip folded back downward. When the top cover 2 is assembled with the folded portion 50 placed on the upper edge of the support frame 13, the rib 23 provided on the lower edge of the top cover 2 is attached to the top of the cleaning dish 5 as shown in FIG. 8. It fits into a groove 51 provided on the top surface of the edge. The upper edge of the cleaning dish 5 is compressed between the top cover 2 and the support frame 13, and the waterproofness of this portion is maintained.

  As shown in FIGS. 12 to 14, the washing dish 5 is provided with an overflow weir 54 inside, and the front side of the overflow weir 54 is divided into a washing part 52 and the rear side is divided into an overflow part 53. Yes. The cleaning part 52 is a part for storing the blade head part Ea of the small electric device E, and includes a rib 55 integrally provided on the wall surface on the overflow weir 54 side, a support part 36 of the head guide 35 disposed on the inner surface of the cleaning dish 5, and The blade head portion Ea is positioned in the front-rear direction. Further, a plurality of convex bands 59 are provided on the bottom surface of the cleaning dish 5, and the blade head part Ea is supported by the convex bands 59 in a state of being slightly lifted from the bottom surface.

  The washing part 52 of the washing dish 5 is provided with a water supply / drain port 56 at its lowest part and two drainage ports 57, 58 at the overflow part 53. The water supply / drain port 56 is connected to the pump P through a connection pipe 126 provided in the base base 12. The drain ports 57 and 58 are connected to connecting pipes 127 and 128 provided on the base base 12. These connecting pipes 127 and 128 are located immediately above the container 7 for storing the cleaning liquid, and the drainage through the drainage ports 57 and 58 is returned to the container 7 through the connecting pipes 127 and 128.

  Here, out of the two drainage ports 57 and 58, the drainage port 57 in a position where the upper surface opening (cleaning liquid inflow portion) is low bears drainage for circulating the cleaning liquid. The drain port 58 having a higher top opening and farther from the overflow weir 54 than the drain port 57 is an emergency when the drain port 57 is clogged for some reason and cannot perform its function. The bottom surface of the overflow portion 53 is an inclined surface that is inclined downward toward the drain port 57 located on one side. Since the cleaning liquid exceeding the overflow weir 54 flows into the drain port 57 vigorously, the drain port 57 is not easily clogged.

  A portion surrounded by a bag-shaped wall body 500 provided on one side of the front edge of the washing dish 5 is for the arrangement of the select button 29 for operation instruction, and the select button 29 exposed on the top cover 2 is arranged. The operation drives the switch on the switch board 27 (see FIG. 5) via the switch rod 290 (see FIG. 6). For this purpose, the operation of the cleaning device 1 can be instructed by the select button 29. At this time, the operation display indicator lamp provided on the switch board 27 is instructed on the top cover 2 via the light guide plate 28. Display accordingly. An indicator lamp for displaying the amount of water in the container 7 is also provided.

  The back surface side is covered with the back cover 23 of the top cover 2, and the support base 6 constituting the support portion S with the back cover 23 is individually attached to the front side via the contact point support member 38 by the spring 37. A plurality of biased contact portions 39 are provided. The contact portion 39 is exposed to the front surface of the support base 6 without protruding from the front surface of the support base 6.

  Above the contact point 39, a magnet 43 and a yoke 44 for attracting the small electric device E are installed. When the blade head portion Ea is fitted into the washing dish 5, the small electric device E is attracted to the support portion S by magnetic attraction by the magnet 43, and the terminal portion Eb of the small electric device E contacts the contact portion 39 and the terminal The state in which the contact pressure is secured by the portion Eb pushing the contact portion 39 against the spring 37 is maintained. Note that the contact between the contact portion 39 and the terminal portion Eb enables power supply to the small electrical device E and signal transmission from the cleaning device 1 to the small electrical device E.

  The main body detection plate 42 arranged in the support portion S and in contact with the plurality of contact portions 39 is separated from the contact portion 39 when the small electric device E is attached and the contact portion 39 is retracted, so that the small electric device E is This is for detecting that the cleaning apparatus 1 is mounted.

  A blowout port 66 to which the motor fan F is mounted is provided on the lower side of the support base 6. The lower edge of the outlet 66 is placed on the upper rear edge of the washing dish 5. The motor fan F sucks air from the suction port 150 located on the back surface of the cleaning device 1 and blows air from the blow-out port 66 toward the blade head portion Ea of the small electrical device E. For this purpose, the air outlet 66 of the motor fan F is directed obliquely downward so that it can be blown and dried from above toward the blade head portion Ea, and further provided with a current plate 67 for changing the air direction more efficiently. .

  A heater mechanism H for heating is installed on the back surface (lower surface) side of the cleaning unit 52 of the cleaning dish 5. The heater mechanism H includes a heater wire, a heater plate, a heater base, a temperature detector for temperature control, and a protection component for abnormal heating (not shown). The heat is transmitted to the blade head portion Ea through the convex band 59 to promote drying of the blade head portion Ea after cleaning.

  The washing dish 5 and the top cover 2 are assembled on the base base 12 via the support frame 13, and the side cover 15 and the front cover 16 are attached so as to surround the outer periphery thereof. Accordingly, when the base base 12 is moved up and down with respect to the bottom plate 11, all the members other than the bottom plate 11 and the container 7 detachably installed on the bottom plate 11 are moved up and down integrally with the base base 12. I do. This vertical movement is for the attachment / detachment operation of the container 7 arranged on the bottom plate 11.

  Next, the container 7 and the filter frame 8 that is detachably disposed in the container 7 will be described with reference to FIGS. The container 7 having an open top surface installed on the bottom plate 11 has a cup shape in which the lateral width on the rear side is narrower than the lateral width on the front side, and a water supply line 70 is described on the inner wall. A plurality of convex raised portions 76 are provided on the lower surface of the container 7 to ensure stability when the container 7 is placed outside the cleaning device 1 and water drops adhere to the lower surface of the container 7 by washing with water or the like. Even if it is not carelessly moved to the place where the container 7 is placed.

  The filter frame 8 includes a bottom plate portion 80 that substantially covers the bottom surface of the container 7, and a partition wall 81 that rises from the rear portion of the bottom plate portion 80 and has both side edges in contact with the inner wall surface of the container 7. 7 is positioned by a convex portion 74 for positioning provided on the inner wall of 7. By the filter frame 8, the inside of the container 7 is formed between the two spaces 7 a and 7 b partitioned by the partition wall 7, and the bottom plate portion 80 that is slightly lifted from the bottom surface of the container 7 and the bottom surface of the container 7. It is partitioned into a total of three spaces with the space 7c. The bottom plate portion 80 is provided with a grid-like rib 85 on the lower surface side thereof, and a concave portion 88 is provided on a portion of the rear upper surface facing the space 7b. When the filter frame 8 is arranged in the container 7, the front edge portion of the peripheral edge is in a state of being spaced from the inner wall surface of the container 7.

  On the upper part of the partition wall 81, a flow dividing portion 82 is provided. The diversion portion 82 includes a transmission port 84 in an inclined surface 83 formed on the upper portion of the partition wall 81, and an inclined surface 85 that is directly below the transmission port 84 and has an inclination opposite to the inclined surface 83. In addition, a filter 89 made of a finer mesh than body hair is disposed on the inclined surface 83 of the flow dividing portion 82.

  The cleaning liquid that does not pass through the filter 89 and the permeation port 84 is separated from the partitioned space 7a between the partition wall 81 and the inner wall of the container 7 to the space 7c between the bottom plate portion 80 and the bottom surface of the container 7, and the front edge of the bottom plate portion 80. Flows into the space 7b on the upper surface side of the bottom plate portion 80 through the gap between the container 7 and the inner wall surface of the container 7. The cleaning liquid that has passed through the filter 89 and the permeation port 84 flows into the space 7 c along the inclined surface 85. The opening area of the permeation port 84 is set so that the cleaning liquid that passes through the filter 89 and the permeation port 84 is larger than the cleaning liquid that does not pass through the space 7a and enters the space 7c.

  When cleaning the blade head portion Ea of the small electrical device E, the switch plate 31 is operated to float the entire surface with respect to the bottom plate 11, and the cleaning liquid is put into the container 7 containing the filter frame 8 and placed on the bottom plate 11. The container 7 is installed in the container. At this time, the container 7 is guided by the guide plate 117 provided on the bottom plate 11 and further positioned by the positioning projection 116. Since this protrusion 116 fits into the engagement recess 77 (see FIG. 17) provided on the outer wall surface of the container 7, the container 7 is also prevented from floating.

  When the entire cleaning device 1 is pushed down, the lower part of the pump P provided on the base base 12 is immersed in the cleaning liquid in the container 7. At this time, the packing 17 attached to the lower surface of the peripheral portion of the base base 12 with the mounting frame 18 is formed on the upper edge of the container 7 so as to protrude to the outer peripheral side, and the lower surface of the base base 12 and This part is waterproofed so as to be sandwiched between the two.

  With respect to the cleaning apparatus 1 in which the container 7 containing the cleaning liquid is set as described above, the blade head portion Ea of the small electric device E is stored in the cleaning dish 5 through the opening 20 on the upper surface thereof, and the terminal of the small electric device E is stored. The part Eb is brought into contact with the contact part 39 of the support part S.

  If cleaning is started by operating the select button 29 of the cleaning apparatus 1 connected to the external power source in this state, the pump P is activated and the cleaning liquid in the container 7 is cleaned through the connection pipe 126 and the water supply / drain port 56. 5 into the cleaning section 52. Then, the cleaning liquid that has passed over the overflow weir 54 of the cleaning dish 5 returns to the inside of the container 7 through the drain port 57 and the connecting pipe 127 that are the first overflow path. Accordingly, the cleaning liquid circulates between the container 7 and the cleaning dish 5.

  In this cleaning, it is preferable to drive the blade in the blade head portion Ea of the small electric device E through the support portion S. The blade head Ea can be cleaned more effectively and quickly.

  By the way, the cleaning liquid in the cleaning dish 5 passes the overflow weir 54 and enters the overflow part 53 and returns to the container 7 from the drain 57 and the connection pipe 127 as described above. 7 is located immediately above the filter 89 to be located in the space 7a. Accordingly, the cleaning liquid containing hair and the like flows down the space 7 a together with a part of the cleaning liquid without being filtered by the filter 89 and enters the space 7 c at the bottom of the container 7. The cleaning liquid that does not contain body hair or the like that has passed through the filter 89 and the permeation port 84 flows toward the concave portion 88 located in the space 7 b by the inclined surface 54. Since the suction port of the pump P is located at the recess 88, the cleaning liquid is sent again to the cleaning dish 5 by the pump P.

  On the other hand, the hair and the cleaning liquid that have entered the space 7c between the lower surface of the filter frame 8 and the bottom surface of the container 7 from the space 7a located on one side of the rear portion of the container 7 spread along the bottom surface of the container 7, and the bottom plate portion 80 of the filter frame 8 It flows into the space 7b from the gap between the front edge and the front inner wall of the container 7. At this time, the cleaning liquid entering the space 7c spreads as described above, and the cleaning liquid sent to the cleaning dish 5 by the pump P is mainly a cleaning liquid that does not include body hair that has passed through the filter 89 and the permeation port 84. In other words, the flow rate through the space 7c is small and the flow rate is considerably low, and the stagnation-like ribs 85 on the lower surface of the bottom plate portion 80 of the filter frame 8 cause stagnation at a number of locations. The hair that is present is deposited in the space 7c.

  Then, the cleaning liquid that has passed through the space 7 c passes through the front side of the container 7, passes over the bottom plate 80 of the filter frame 8, and then enters the recess 88 where the suction port of the pump P is open near the rear of the container 7. In addition, since there is a bottom plate portion 80 between the deposited hair and the suction port, the pump P hardly sucks the hair again and returns it to the washing dish 5.

  In addition, the space 7c has a volume that can secure a body hair accumulation amount by a washing operation of several tens of times. And if a user takes out the container 7 from the washing | cleaning apparatus 1 and removes the filter frame 8, he can wash away the accumulated hair and can regain the initial washing | cleaning capability by putting in a new washing | cleaning liquid after this. . The aforementioned collar 72 provided on the upper edge of the container 7 is formed so as to project to the outer peripheral side. For this reason, when the opening of the container 7 is lowered to discard the cleaning liquid in the container 7, the cleaning liquid ( And hair) can be discharged smoothly. In addition, although the collar 72 is provided in order to ensure the rigidity for water stop, when the rigidity can be ensured by the thickness of the side wall of the container 7, the collar 72 is not necessary.

  When the cleaning is completed and the pump P is stopped, the cleaning liquid in the cleaning section 52 in the cleaning dish 5 is naturally dropped from the supply / drain port 56 to the connection port 126 and the pump P (between the impeller 123 and the pump cover 124). ) To return to the container 7. The impeller 123 part is immersed in the cleaning liquid in the container 7 and the cleaning liquid in the cleaning unit 52 contains almost no body hair at the end of cleaning. It never happens. Further, even if the drain outlet 57 in the overflow portion 53 is clogged during the cleaning operation, the cleaning liquid does not overflow from the cleaning dish 5 because the drain outlet 58 exists separately.

  When the cleaning is finished and the cleaning liquid is collected in the container 7, the motor fan F and the heater H are energized to promote drying of the blade head Ea. Here, the motor fan F is provided in the overflow part 53 on the rear side of the cleaning dish 5 so that the lower end of the motor fan F is positioned below the overflow weir 54 (the level of the cleaning liquid in the cleaning dish 5). Because it can.

  Even if the drain outlet 57 and the connecting pipe 127 which are the first overflow paths are clogged, the second overflow path consisting of the drain outlet 58 and the connecting pipe 128 removes the cleaning liquid in the cleaning dish 5 as described above. In order to return to the container 7, the cleaning liquid does not overflow from the cleaning dish 5. Here, the connecting pipe 128 is not located above the filter 89, and as shown in FIG. 1, the cleaning liquid passing through the drain port 58 and the connecting pipe 128 flows down directly into the space 7b in the container 7. Therefore, even if the cause of clogging is filth deposited on the filter 89, the function as the second overflow path is not lost.

  In the above embodiment, the height of the cleaning liquid inflow portion at the drain outlet 57 (first overflow path) and the drain outlet 58 (second overflow path) is different, as shown in FIG. In addition, the heights of both of the cleaning liquid inflow portions may be the same.

  In addition, although two overflow paths are provided, it is of course possible to provide three or more overflow paths, and the filter 89 may be arranged inside the overflow path. good.
