Description

Cleaning equipment for electrical equipment

The present invention relates to a cleaning device for electrical equipment such as an electric razor or a hair removal device that requires periodic cleaning.

For example, Japanese Patent No. 36552393 (US Patent No. 5,711,328) discloses a cleaning device. The cleaning device includes a cradle structure for receiving the shaving head of the shaving device, a cleaning liquid container, and a supply device for supplying the cleaning liquid from the cleaning liquid container to the cradle structure. The cradle structure is connected to the cleaning liquid container via an overflow device and / or an outlet port.

This cleaning device is configured to circulate the cleaning liquid in the cleaning liquid container between the cleaning liquid container and the cradle structure. For this purpose, in the cleaning device, a filter is provided in the cleaning liquid container. However, since it is necessary to replace the cleaning liquid container including the filter, it is not possible to replace only the filter.

Japanese Patent Application Publication No. 2008-302093 discloses a cleaning device. Also in this cleaning apparatus, the filter formed by the filter frame and the filtration element is exchanged. Japanese Patent Application Publication No. 2009-504299 discloses an apparatus for cleaning an electric hair cutter. In this apparatus, it is necessary to remove a filter having a three-dimensional structure (container shape).

It comprises a cleaning ball 5, a top cover 2 having an opening 20, a support base 6 to which the connecting portion is attached, a side cover 15 that covers the side, a front cover 16 that is disposed on the front.

The bottom plate 11 is provided with

guide columns

110 and 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 push-up

rods

111 and 111 having

springs

112 and 112 disposed in the

guide columns

110 and 110, respectively.

On the base substrate 12, a switch plate 31 is slidably arranged to the left and right. The switch plate 31 is biased in one direction by a spring 32, and one end of the switch plate 31 is exposed to the outside from the side cover 15. The switch plate 31 includes engaging portions with

hook portions

115 and 115 formed at the upper ends of the

The support base 6 includes a plurality of contact portions 39 individually biased forward by a spring 37 via a contact portion support member 38. 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 electric equipment E are installed. As shown in FIG. 3, when the blade head portion Ea is fitted into the cleaning ball 5, the electric device E is attracted to the support portion S by magnetic adsorption by the magnet 43, and the terminal portion Eb included in the electric device E is connected to the contact portion 39. To touch. Further, the terminal portion Eb pushes the contact portion 39 against the spring 37 to maintain a state in which the contact pressure is secured. Note that the contact between the contact portion 39 and the terminal portion Eb enables power supply to the electric device E and signal transmission from the cleaning device 1 to the electric device E.

As shown in FIG. 6, 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 electrical device E is attached and the contact portion 39 is retracted. This is for detecting that the electric device E is mounted on the cleaning device 1.

A blow-off port 66 to which the motor fan F is attached is provided on the back side of the support base 6. The lower edge of the blowout port 66 is placed on the upper rear edge of the cleaning ball 5. As shown in FIG. 11, 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 blowout port 66 toward the blade head portion Ea of the electric 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. As shown in FIGS. 7 and 11, a plurality of rectifying plates 67 are provided for changing the direction of the wind more efficiently.

7 and 11, a heater unit H for heating is installed on the back surface (lower surface) side of the cleaning unit 52 of the cleaning ball 5. The heater unit H includes a heater wire, a heater plate, a heater base, a temperature detector for temperature control, and protective parts for abnormal heating (not shown). The heater unit H transmits heat from the heater wire to the blade head portion Ea through the heater plate, the cleaning ball 5, and the convex band 59 of the cleaning ball 5, and promotes drying of the blade head portion Ea after cleaning.

7 and 9, the cleaning ball 5 and the top cover 2 are assembled on the base base 12 via the support frame 13. As shown in FIG. 2, the side cover 15 and the front cover 16 are attached so as to surround the outer periphery of the main part shown in FIG. Therefore, 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 move up and down integrally with the base base 12. 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 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. A water supply line 70 is formed on the inner wall of the container 7. A plurality of convex raised portions 76 are provided on the lower surface of the container 7. As a result, the stability of the container 7 when the container 7 is placed outside the cleaning device 1 is ensured, and even if water drops adhere to the lower surface of the container 7 due to washing or the like, water drops are inadvertently placed at the place where the container 7 is placed. Transfer is prevented.

As shown in FIGS. 15 and 16, the filter frame 8 rises from the bottom plate portion (second bottom plate) 80 that substantially covers the bottom surface of the container 7 and the rear portion of the bottom plate portion 80, and both side edges are in contact with the inner wall surface of the container 7. A partition wall 81 is provided, and the container 7 is positioned by positioning

convex portions

74 and 74 provided on the inner wall of the container 7. As shown in FIGS. 16, 17 A and 17 B, the filter frame 8 allows the inside of the container 7 to have two

spaces

7 a and 7 b partitioned by a partition wall 81, and a bottom plate part that is slightly lifted from the bottom surface of the container 7. It is partitioned into a total of three spaces 80 and a bottom space 7 c between the bottom surface of the container 7. As shown in FIGS. 18A to 18D, the bottom plate portion 80 includes a grid-like rib 85 on the lower surface side thereof, and a recess 88 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.

In short, as shown in FIGS. 16, 17 A and 17 B, the cleaning device 1 divides the space in the container 7 into an upper space and a bottom space 7 c as a gap space extending to the bottom of the container 7. 2 bottom plate) and a partition wall 81 that divides the upper space into a storage space and a part of the capture space. The storage space is a space 7b for mainly storing the cleaning liquid. The capture space is a space for capturing dirt and debris (such as sawdust) contained in the cleaning liquid from the overflow path C2. Here, the later described inclined surface 83,

transmission ports

84 and 84, inclined surface 86, filter 89, and openings on the inclined surface 86 are optional and not essential. Therefore, a part of the capture space includes at least a space 7a for allowing the cleaning liquid containing dirt and debris from the overflow path C2 to flow into the gap space 7c, and constitutes the capture space together with the gap space 7c. As an example, the partition wall 81 may be a partition that divides the upper space into the storage space and only the space 7a for allowing the cleaning liquid containing dirt and debris from the overflow path C2 to flow into the gap space 7c. This space 7a constitutes a capture space together with the gap space 7c. In this structure, dirt and debris contained in the cleaning liquid from the overflow path C2 can be confined in the gap space 7c. Further, since the gap space 7c is formed as a gap space that spreads to the bottom of the container 7 by the bottom plate portion 80, dirt and debris contained in the cleaning liquid from the overflow path C2 are prevented from rising from the gap space 7c into the space 7b. Thus, dirt and debris can be reliably trapped in the gap space 7c.

Desirably, as shown in FIG. 17A, the bottom plate portion 80 (second bottom plate) in the container 7 is set back from the inner wall of the container 7 on the first side in the first direction of the cleaning device 1, A gap 71 as an exit of the capture space is formed between one end of the set-back bottom plate portion 80 and the inner wall of the container 7. The gap 71 communicates with the storage space. In this structure, dirt and debris from the overflow path C2 can be reliably confined in the gap space 7c. In one example, a portion of the capture space is disposed on the second side of the cleaning device in the first direction. In this structure, since the entrance and the exit of the capture space can be separated as much as possible, the cleaning liquid from which dirt and debris are reliably removed in the capture space can be returned to the storage space. In one example, the capture space has only the opening of the space 7 a and the gap 71 between the front edge of the bottom plate portion 80 and the inner wall surface of the container 7.

As shown in FIGS. 15, 17 A and 17 B, a flow dividing portion 82 is provided on the upper portion of the partition wall 81. The diversion portion 82 is provided with

transmission ports

84 and 84 in an inclined surface 83 formed on the upper portion of the partition wall 81, and an inclined surface 86 that is directly below the

transmission ports

84 and 84 and has an inclination opposite to the inclined surface 83. With. As shown in FIGS. 15 and 16, a filter 89 made of a finer mesh than body hair or the like is detachably disposed on the inclined surface 83 of the flow dividing portion 82.

As shown in FIGS. 16 and 17B, the cleaning liquid that is returned into the partition wall 81 and does not pass through the filter 89 and the permeation port 84 enters the partitioned space 7a between the partition wall 81 and the inner wall of the container 7. Subsequently, the cleaning liquid passes through the space 7a, the bottom space 7c between the bottom plate portion 80 and the bottom surface of the container 7, and the gap 71 between the front edge of the bottom plate portion 80 and the inner wall surface of the container 7 (see FIG. 17A). , Flows into the space 7b on the upper surface side of the bottom plate portion 80. As shown in FIGS. 16 and 17B, the cleaning liquid that has passed through the filter 89 and the permeation port 84 flows into the space 7 b along the inclined surface 86. The opening area of the permeation port 84 is set so that the cleaning liquid passing through the filter 89 and the permeation port 84 is larger than the cleaning liquid entering the bottom space 7c through the space 7a without passing through these.

As shown in FIGS. 4 and 5, when cleaning the blade head portion Ea of the electric device E, the body of the cleaning device 1 is floated with respect to the bottom plate 11 by operating the switch plate 31, and the filter frame 8 is The cleaning liquid is put into the container 7 accommodated, and the container 7 is set on the bottom plate 11. At this time, the container 7 is guided by the

guide plates

117 and 117 provided on the bottom plate 11 and further positioned by the positioning protrusion 116. Since this protrusion 116 fits into an engagement recess 77 (see FIG. 17B) provided on the outer wall surface of the container 7, the container 7 is also prevented from floating.

When the main body side of the 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. As shown in FIGS. 5, 7, and 11, at this time, the packing 17 attached to the lower surface of the peripheral portion of the base base 12 with the attachment frame 18 is formed on the upper edge of the container 7 so as to protrude to the outer peripheral side. This portion is waterproofed so as to be sandwiched between the portion 72 and the lower surface of the base base 12.

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 electric device E is housed in the cleaning ball 5 through the opening 20 on the upper surface thereof, and the terminal portion Eb of the electric device E is stored. Is brought into contact with the contact portion 39 of the support portion S.

If cleaning is started by operating the select button 29 of the cleaning device 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 ball 5 returns to the inside of the container 7 through the drain port 57 and the connection pipe 127. Accordingly, the cleaning liquid circulates between the container 7 and the cleaning ball 5.

In this cleaning, it is preferable that the control unit drives the blade in the blade head portion Ea of the electric device E through the support portion S (the contact portion 39 or the like). The blade head Ea can be cleaned more effectively and quickly.

By the way, the cleaning liquid in the cleaning ball 5 passes the overflow weir 54 and enters the overflow portion 53 and returns to the container 7 from the drain port 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 body hair or the like flows down the space 7 a together with a part of the cleaning liquid without passing through the filter 89 and enters the bottom space 7 c 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 transmission port 84 flows toward the concave portion 88 located in the space 7 b by the inclined surface 86. Since the opening of the pump P is located at the recess 88, the cleaning liquid is sent again to the cleaning ball 5 by the pump P.

On the other hand, the hair and cleaning liquid that has entered the bottom 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 spreads along the bottom surface of the container 7, and the bottom plate portion of the filter frame 8 80 flows into the space 7b from the gap between the leading edge of the container and the front inner wall of the container 7. At this time, the cleaning liquid that has entered the bottom space 7 c spreads as described above, and the cleaning liquid that is pumped out to the cleaning ball 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. Since the flow rate through the bottom space 7c is small and the flow rate is considerably low, and the grid-like ribs 85 on the lower surface of the bottom plate portion 80 of the filter frame 8 are retained in many places, the cleaning liquid The hair and the like contained in the sediment will be deposited in the bottom space 7c.

Then, the cleaning liquid that has passed through the bottom 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 opening 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 body hair that has been deposited and the opening of the pump P, the pump P hardly sucks the body hair again and returns it to the cleaning ball 5.

In addition, the bottom 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 flange 72 provided on the upper edge of the container 7 is formed so as to protrude 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 Body hair, etc.) can be discharged smoothly. In addition, although the collar part 72 is provided in order to ensure the rigidity for water stop, when rigidity can be ensured with the thickness of the side wall of the container 7, the collar part 72 is not required.

When the cleaning is completed and the pump P is stopped, the cleaning liquid in the cleaning unit 52 in the cleaning ball 5 is naturally dropped from the supply / drain port 56 to the connection pipe 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 ball 5 because another drain outlet 58 exists.

When the cleaning is completed and the cleaning liquid is collected in the container 7, the motor fan F and the heater of the heater unit H are energized to promote the drying of the blade head Ea.

The grid-like ribs 85 generate a stagnant flow in the bottom space 7c to promote sedimentation and deposition of the dirt factor and prevent the dirt factor from rising from the bottom surface of the container 7 when the cleaning apparatus 1 is moved. Particularly effective, the rib 85 may be provided not on the bottom plate portion 80 of the filter frame 8 but on the bottom surface side or inner wall of the container 7. Of course, it is preferable to provide the bottom plate 80 on the lower surface in consideration of washing away the dirt factor accumulated in the container 7.

In the present embodiment, the cleaning device 1 includes a bottom plate portion 80 (second bottom plate) that divides the space in the container 7 into an upper space and a bottom space 7c as a gap space that extends to the bottom of the container 7, and an upper space. A partition wall 81 that divides the storage space into a storage space and a part of the capture space. The storage space is a space 7b for mainly storing the cleaning liquid. The capture space is a space for capturing dirt and debris (such as sawdust) contained in the cleaning liquid from the overflow path C2. Part of the capture space is a flat shape for removing dirt and debris from the cleaning liquid from the overflow path C2, and returning a part of the cleaning liquid from the overflow path C2 from which the dirt and debris have been removed to the storage space 7b. It includes a filter 89 and a space 7a for allowing the dirt and debris removed by the filter 89 to flow into the gap space 7c together with the remaining portion of the cleaning liquid from the overflow path C2. This space 7a constitutes a capture space together with the gap space 7c. In this structure, since the filter 89 is used, the contamination factor contained in the cleaning liquid can be efficiently captured in the container 7. Further, since the filter 89 is flat, the size of the filter 89 can be made smaller than that of a three-dimensional structure filter. Further, only the filter 89 can be easily removed from the container 7. Furthermore, the filter 89 can be easily cleaned. For this reason, the filter 89 is desirably disposed in the container 7 so as to be detachable.
