  The on-off valve 9 is used to open and close the vent 53 of the tank 5. The on-off valve 9 is housed in front of the lower part of the housing 3 and is disposed below the electrical components for controlling the device built in the device 1, such as the fan 16, the heater 17, the pump 7, and the like. As shown in FIG. 5, the on-off valve 9 is composed of a solenoid valve and has a base 91 having a pipe 91 a connected to the airtight path 15, an electromagnet 92 fixed to the base 91, and the base 91. And a long plate-shaped iron piece 93 that is freely rotatable, and a seal member 94 provided at the tip of the iron piece 93. The opening of the pipe 91a is provided facing downward. With the above configuration, when the electromagnet 92 is energized, the iron piece 93 is attracted to the electromagnet 92 and the outlet of the pipe 91a is closed by the seal member 94. When the electromagnet 92 is not energized, the iron piece 93 is separated from the electromagnet 92 by its own weight. The outlet of the pipe 91a is opened. The on-off valve 9 is closed when the cleaning liquid is discharged from the discharge port 51 of the tank 5, and is otherwise open.

  The cleaning operation of the cleaning apparatus 1 configured as described above will be described with reference to FIG. FIG. 6 schematically shows the flow of the cleaning liquid during cleaning. Here, it is assumed that the electric razor 2 is attached to the cleaning device 1 and there is no cleaning liquid in the tray 4. When the operation button 33 (see FIG. 1) is pressed, the on-off valve 9 is closed and the inside of the tank 5 is airtight. Thereafter, the pump 7 is operated, air is sucked from the cartridge 8 side via the path 13, and the pressurized air is sent to the inlet 52 of the tank 5 via the path 14. This pressurized air raises the pressure in the inflow chamber 55, thereby depressing the water surface of the cleaning liquid. As a result, the water surface of the discharge chamber 54 rises and the cleaning liquid in the tank 5 is discharged from the discharge port 51. The discharged cleaning liquid is supplied to the tray 4 through the path 10. Here, since the amount of cleaning liquid supplied to the tray 4 is set to be larger than the amount of cleaning liquid discharged from the outlet 42, the water level of the cleaning liquid in the tray 4 rises.

  When the inside of the tray 4 is filled with the cleaning liquid, a drive signal is transmitted from the contact member 31a to the electric shaver 2, and the motor built in the head unit 21 is driven. As a result, hair chips, sebum and the like are washed out from the head portion 21. The cleaning liquid containing debris, sebum, etc. flows into the cartridge 8 from the discharge port 42 through the path 11, and the cleaning liquid in the tray 4 exceeding the predetermined water level passes through the path 12 from the overflow portion 6 to the cartridge 8. Flow into. The cleaning liquid that has entered the cartridge 8 is filtered by the filter 8a to remove hair chips and sebum. The pump 7 sucks the cleaning liquid from the cartridge 8 via the path 13 and sends it to the inlet 52 of the tank 5 via the path 14. Thereafter, the circulation of the cleaning liquid by the pump 7 is continued.

  When the head unit 21 is cleaned for a predetermined time, a stop signal is transmitted from the contact member 31a to the electric shaver 2, and the motor built in the head unit 21 is stopped. At the same time, the on-off valve 9 is opened, and the inside of the pump 7 is opened to the atmosphere. Thereby, the liquid level of the cleaning liquid in the inflow chamber 55 rises, the liquid level in the discharge chamber 54 decreases, and the supply of the cleaning liquid to the tray 4 is stopped. The pump 7 continues to feed the cleaning liquid thereafter, and the cleaning liquid in the tray 4 is collected into the tank 5. When there is no cleaning liquid in the tray 4, the pump 7 is stopped, and then the fan 16 and the heater 17 are operated to dry the head portion 21.

  Next, the flow state of the cleaning liquid in the tank 5 will be described with reference to FIG. Since air together with the cleaning liquid is supplied from the pump 7 to the inflow port 52, the cleaning liquid W in the tank 5 is in a bubbled state, and the water level of the cleaning liquid W in the tank 5 is higher than the water level at the time of filling. When the water level of the cleaning liquid W in the tank 5 reaches the partition wall 58, the upper space inside the tank 5 is partitioned into the vent 53 side and the inlet 52 side, and the foamed cleaning liquid W enters the vent 53 side. Flow is suppressed. Further, when the cleaning liquid W passes through the notch 58a (see FIG. 3) of the partition wall 58, the bubbles in the cleaning liquid W are removed or reduced. Therefore, before the water level of the cleaning liquid W reaches the vent 53, the cleaning liquid W can be discharged from the discharge port 51, and the cleaning liquid can be prevented from flowing into the vent 53.

  As described above, according to the cleaning apparatus 1 according to the present embodiment, the cleaning liquid does not flow out from the on-off valve 9 through the airtight path 15 by preventing the cleaning liquid from flowing into the vent 53, and thus for controlling the apparatus. The electrical parts can be protected from the cleaning liquid. Moreover, since the on-off valve 9 is below the electrical component, the cleaning liquid is not applied to the electrical component even when the cleaning solution flows into the vent 53. Moreover, since the opening of the on-off valve 9 is arranged downward, the cleaning liquid that has flowed into the vent 53 can be smoothly discharged from the opening of the on-off valve 9.

  Next, various modifications of the tank 5 used in the cleaning device of the above embodiment will be described with reference to FIGS. The tank 5 of the present apparatus shown in FIG. 8 is provided with an enclosure 59 surrounding the vent 53 as a partition wall. The enclosure 59 includes side plates 59a and 59b and a back plate 59c extending downward from the upper wall inside the tank 5, and a bottom plate 59d extending rearward from the front wall of the tank 5, and the plates are connected to each other. A small hole 59e is formed in the side plate 59a to communicate the enclosed internal space with the upper space inside the tank 5. Also in the cleaning apparatus of this modification, the same effect as the above embodiment can be obtained. In addition, since the periphery of the vent 53 is partitioned by the enclosure 59, the cleaning liquid W does not flow into the vent 53 even when the cleaning liquid W in the tank 5 rises rapidly. Further, the flow of the cleaning liquid W flowing toward the vent 53 is effectively suppressed by the small holes 59e.

  The tank 5 of the present apparatus shown in FIG. 9 has a float 60 that closes the vent 53 when the water level of the cleaning liquid W in the tank 5 rises as a sealing means instead of the partition wall, and a holding plate that makes the float 60 up and down. 61 and a vent 53 is provided on the upper surface of the tank 5. The float 60 is disposed below the vent 53 and has a shape along the inner wall of the tank 5. As shown in the drawing, the holding wall 61 may be a member having the same configuration as the partition wall 58 described above, or may be constituted by a column parallel to the side surface of the float 60. According to the cleaning apparatus of the present modification, the vent 53 is closed by the float 60 when the water level of the cleaning liquid W in the tank 5 rises, so that the cleaning liquid can be reliably prevented from flowing into the vent 53.

  In addition, this invention is not restricted to the structure of the said embodiment, A various deformation | transformation is possible in the range which does not change the meaning of invention. For example, the cartridge 8 may not be provided between the tray 4 and the pump 7. Moreover, the apparatus structure which has the tank 5 between the saucer 4 and the pump 7 may be sufficient. In addition, as a configuration for removing bubbles of the cleaning liquid, a relatively small diameter hole may be formed in the partition wall 58 instead of the notch 58a.
