  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in FIG. 4, the local cleaning device includes a local cleaning device main body 1 having a mechanism for cleaning a human body local part, an operation unit 2 for a user to select and operate a cleaning method, and the like. The main control unit (not shown) for controlling the toilet seat temperature, the washing temperature, the washing flow rate, and the like according to the signal, and the toilet seat B for the user to sit on.

  As shown in FIG. 5, the local cleaning device main body 1 includes a water supply valve 11 for supplying / stopping water from a water source, a hot water tank 12 for storing water from the water source and heating it with a heater to make hot water, and a human body local part The cleaning nozzle 3 for jetting water for cleaning the water, the water supply path 13 connecting the water supply valve 11 and the cleaning nozzle 3, and the water in the hot water tank 12 disposed downstream of the hot water tank 12 in the water supply path 13 The water pump 14 for conveying to the nozzle 3 and the cleaning liquid supply unit 4 for supplying the cleaning liquid to the water supply path 13 are configured.

  The cleaning liquid supply unit 4 includes a cleaning liquid holding unit 5 for storing the cleaning liquid, a cleaning liquid inlet 41 for mixing the cleaning liquid into the water supply path 13 connecting the water supply valve 11 and the cleaning nozzle 3, the cleaning liquid holding unit 5, and the cleaning liquid. The cleaning liquid supply path 42 is connected to the injection port 41, and the cleaning liquid supply pump 43 is disposed in the cleaning liquid supply path 42 and transports the cleaning liquid. As the cleaning liquid supply pump 43, for example, a gear pump or a diaphragm pump is used. Furthermore, a backflow prevention valve 44 for preventing water from entering the cleaning liquid holding unit 5 is provided on the upstream side of the cleaning liquid supply pump 43 in the cleaning liquid supply path 42. As the backflow prevention valve 44, for example, a direct acting or diaphragm electromagnetic valve, a duckbill valve or the like is used.

  As shown in FIG. 6, the washing nozzle 3 includes a butt washing nozzle 31, a bidet washing nozzle 32, a nozzle washing nozzle 33 for washing the butt washing nozzle 31 and the bidet washing nozzle 32, and a toilet bowl for washing the toilet bowl inner surface. The cleaning nozzle 34 and a flow path switching mechanism 35 for switching the flow path to these nozzles are configured.

  As shown in FIG. 7, the buttocks cleaning nozzle 31 includes a cylindrical cylinder 36 having a water channel therein and a fluid element 37 disposed at the tip of the cylinder 36. The cylinder 36 is moved forward by being pushed out by water pressure (see FIG. 7B), and moved backward by the force of the spring 39 contracting when the water pressure is lowered (see FIG. 7A). It has become.

  The cylinder 36 may be driven by using an actuator such as a motor instead of using the water pressure of the washing water. As shown in FIG. 8, the fluid element 37 is composed of a total of three water channels, two circuit-shaped water channels 38a and 38a and a water channel 38b facing the jet port 36a, and the mixed water flowing through these water channels is a junction of the water channels. By colliding with each other, the air mixed in the mixed water becomes finer and becomes foamy and is ejected from the ejection port to the local body part.

  As the flow path switching mechanism 35, for example, a rotary switching valve driven by a stepping motor is used. By switching the flow path with the flow path switching mechanism 35, the cleaning liquid can be mixed with the hot water from the hot water tank 12 and ejected from the hip cleaning nozzle 31 or the bidet cleaning nozzle 32. Further, the mixed water can be ejected to the inner surface of the toilet bowl by the toilet cleaning nozzle 34 or can be ejected from the nozzle cleaning nozzle 33 toward the cleaning nozzles 31 to 34 (see FIG. 9).

  The water pump 14 shown in FIG. 5 functions to change the cleaning flow rate according to a control signal input from a main control unit (not shown) and keep it constant. Instead of controlling the water pump 14 as a means for changing the cleaning flow rate, it may be controlled using a motor. In this case, the amount of water can be changed by changing the cross-sectional area of the flow path in accordance with a signal from the main control unit. In addition, when an electromagnetic valve is used, the amount of water can be changed by changing the flow path area. The water pump 14 may be omitted. In this case, the solenoid valve type water supply valve 11 may be opened by operating the cleaning operation key of the operation unit 2, and the cleaning water may be directly fed by the supply water pressure.

  The hot water tank 12 may be omitted. In this case, as a heat exchanger, a ceramic or seed type heater or the like is used, and the feed water is directly heated and supplied to the cleaning nozzle 3.

  Next, the cleaning liquid holding unit 5 will be described. As shown in FIG. 1, the cleaning liquid holding part 5 is mainly composed of a cleaning liquid holding part main body 51 and a cleaning liquid holding part lid 52 formed of, for example, opaque PP resin. In this embodiment, the cleaning liquid holding part main body 51 has a substantially box shape that opens upward in the front-rear direction, and the cleaning liquid holding part lid 52 is attached to the edge of the opening above the cleaning liquid holding part main body 51 and The opening is closed, and the cleaning liquid holding part main body 51 and the cleaning liquid holding part lid 52 are integrally formed by, for example, ultrasonic welding or the like.

  A front-side remaining amount display window 60 is provided as a remaining amount confirmation means 6 on the front (front side) of the outer shell of the cleaning liquid holding unit 5. The front-side remaining amount display window 60 is formed with a vertically long opening in the front wall portion of the outer shell of the cleaning liquid holder main body 51. The opening has a substantially rectangular shape when viewed from the front. The remaining amount display window 60 formed in (1) is welded and fixed by ultrasonic welding or the like. The cleaning liquid holding unit 5 is in a state where the outer surface of the cleaning liquid holding unit main body 51 is exposed when the cleaning liquid holding unit 5 is attached to the local cleaning device main body 1 (see FIG. 4). The liquid level of the cleaning liquid in the cleaning liquid holding unit 5 can be seen through the display window 60, and the remaining amount can be confirmed. In the present embodiment, the front end portion of the cleaning liquid holding unit 5 protrudes forward from the local cleaning apparatus main body 1, and a later-described remaining amount confirmation window 61 provided at the front end portion of the upper surface of the cleaning liquid holding unit 5 is provided. It will be exposed.

  Since the remaining amount display window 60 is formed thinner than other portions of the cleaning liquid holding part main body 51 of the cleaning liquid holding part 5 as shown in FIG. 10, the liquid level of the cleaning liquid in the cleaning liquid holding part 5 is the remaining amount. It is easier to see through the display window 60.

  Although not shown in particular, the remaining amount display window 60 may be formed in a convex lens shape. In this case, the liquid level of the cleaning liquid can be easily seen through the remaining amount display window 60.

  Further, the remaining amount display window 60 disposed on the front surface of the cleaning liquid holding unit 5 is formed, for example, tilted about 10 degrees with respect to the vertical direction so as to protrude forward as it approaches the bottom surface of the cleaning liquid holding unit 5. Also good. In the present embodiment, as shown in FIG. 1, the front part of the cleaning liquid holding part 5 in which the remaining amount display window 60 is provided is formed so as to be inclined as described above. By doing in this way, it becomes possible to easily confirm the liquid level in the cleaning liquid holding part 5 through the remaining amount display window 60 even when the user stands while entering the room.

  The remaining amount confirmation window 61 is provided in an opening provided on the upper surface of the front end portion protruding forward from the local cleaning device main body 1 of the cleaning liquid holding portion 5 (that is, the front end portion of the cleaning liquid holding portion lid 52). It is made of, for example, a synthetic resin having properties. A float 94 that protrudes downward and moves up and down in the float pipe 93 is inserted below the portion of the cleaning liquid holder 52 where the remaining amount confirmation window 61 is formed. The float pipe 93 is a straight part from the upper end part to the vicinity of the lower end part, and the lower side of the straight part is a bent part that bends away from the straight part of the float pipe 93 on the upper side as it is bent downward. The float 94 is positioned outside the main body of the float tube 93 in plan view at the tip (lower end) of the bent portion, and the float 94 cannot be seen from the upper end opening of the float tube 93 through the remaining amount confirmation window 61.

In this case, in the state where the cleaning liquid is stored in the cleaning liquid holding part 5, the float 94 is positioned on the straight part of the float pipe 93 as shown in FIG. When the float 94 can be seen from the upper end opening and the cleaning liquid is not stored in the cleaning liquid holding part 5, the float 94 is located at the bent part of the float pipe 93 and floats through the remaining amount confirmation window 61 as shown in FIG. The float 94 cannot be seen from the upper end opening of the pipe 93,
According to the above configuration, the seated user can recognize that the cleaning liquid remains in the cleaning liquid holding unit 5 when the float 94 can be seen from the remaining amount confirmation window 61, and the remaining amount confirmation window 61. When the float 94 cannot be seen, it can be recognized that no cleaning liquid remains in the cleaning liquid holding unit 5. As a result, the user removes the cleaning liquid holding part 5 from the local cleaning apparatus body 1 and lifts the case to estimate the weight, or the user removes the cleaning liquid holding part 5 from the local cleaning apparatus body 1 and supplies the cleaning liquid supply port. The remaining amount can be confirmed without removing the lid of the container and visually confirming that the cleaning liquid is no longer mixed with the hot water after cleaning. .

  Next, still another example of the cleaning liquid holding unit 5 will be described with reference to FIGS. The illumination transmission window 71 forms an illumination irradiation port 7 at the rear of the upper surface of the cleaning liquid holding unit lid 52 of the cleaning liquid holding unit 5 and attaches the illumination transmission window 71 to the front of the upper surface of the cleaning liquid holding unit lid 52. An opening 52c is formed, and a viewing window 62 is attached to the viewing window opening 52c to form the remaining amount confirmation means 6.

  As shown in FIG. 12, the cleaning liquid holding unit lid 52 is provided with an illumination irradiation port 7. On the other hand, the LED corresponding to the illumination irradiation port 7 of the local cleaning apparatus main body 1 to which the cleaning liquid holding unit 5 is attached is provided. An irradiating means 9 is provided, and when the irradiating means 9 is turned on, the inside of the cleaning liquid holding unit 5 is irradiated through the illumination irradiation port 7.

  The illumination irradiation port 7 is provided with an illumination transmission window 71 formed of a member having light permeability, such as a resin. As shown in FIG. 11, the illumination transmission window 71 is formed smaller than the illumination irradiation port 7 formed in the cleaning liquid holding unit lid 52, and the illumination transmission window 71 extends from the cleaning liquid holding unit lid 52 to the illumination irradiation port 7. It is locked to the locking portion 52a projecting from the lower side and arranged at the illumination irradiation port 7. At this time, since the illumination transmission window 71 is smaller than the illumination irradiation port 7, the illumination transmission port 71 does not completely close the illumination irradiation port 7, and a gap 72 is generated. By doing in this way, compared with what does not obstruct | occlude the illumination irradiation opening 7 at all, since the water | moisture content in the washing | cleaning liquid in the washing | cleaning liquid holding | maintenance part 5 becomes hard to evaporate, problems, such as a washing | cleaning liquid adhering, can be avoided. In addition to this, by fixing with a certain gap 72, when the cleaning liquid supply means 43 sucks the cleaning liquid, air flows into the cleaning liquid holding part 5 and the cleaning liquid holding part 5 has a negative pressure. Is prevented.

  The observation window 62 is a transparent member, and is formed of the same material as that of the illumination transmission window 71, for example. The cleaning liquid holding unit 5 is mounted on the lower side of the local cleaning device main body 1. In this example, the front portion of the cleaning liquid holding unit 5 is forward of the local cleaning device main body 1 in the mounted state. The viewing window 62 formed on the upper surface is exposed and can be seen by the user seated on the toilet seat.

  An extended portion 92a having a substantially L shape with a lower end bent forward is provided under the illumination transmitting window 71, and a substantially L with a lower end bent rearward under the viewing window 62. An extending portion 92b having a letter shape is provided. The extending portions 92a and 92b are made of a solid member made of a synthetic resin such as AS or acrylic, for example, and the cylindrical side surface is a reflecting portion that reflects light propagating through the extending portions 92a and 92b. And the lower ends thereof are opposed to each other. Then, light incident from above the illumination transmission window 71 is transmitted while being reflected by the cylindrical side surface of the extended portion 92a and irradiated from the lower end portion, and the light is emitted from the extended portion 92b of the observation window 62. The light enters from the lower end portion, passes through the extended portion 92a while being reflected by the cylindrical side surface, and is guided upward from the viewing window 62.

  In the present embodiment, a float pipe 93 in which a float 94 is inserted is disposed between the opposite end portions of the extending portion 92a and the extending portion 92b. The float tube 93 is a hollow tube or square tube, is formed of a translucent member, and is arranged from the lower end portion in the cleaning liquid holding unit 5 to the vicinity of the upper end portion. A float 94 having a light shielding property is arranged in the float pipe 93 so as to be movable up and down. The float pipe 93 is provided with a communication hole (not shown) communicating with the outside of the float pipe 93 at the lower end, and the liquid level of the cleaning liquid outside the float pipe 93 in the cleaning liquid holding part 5 and the liquid level inside the float pipe 93 The float 94 is positioned at the liquid level.

  In this cleaning liquid holding part 5, when the cleaning liquid remains in the cleaning liquid holding part 5, the float 94 is positioned above the lower end of the float pipe 93 (and the cleaning liquid holding part 5), while the viewing window 62 Since the leading end portions of the extending portions 92a and 92b are located at the lower end portion of the cleaning liquid holding portion 5, in this case, the light incident from above the illumination transmission window 71 as described above extends the extending portions 92a and 92b. Through the viewing window 62 and the light can be seen while the user is seated.

  When the cleaning liquid does not remain in the cleaning liquid holding part 5, the float 94 is located at the lower end of the float pipe 93 (and the cleaning liquid holding part 5), and the leading ends of the extension parts 92a and 92b of the observation window 62 facing each other. In this case, the light incident from above the illumination transmission window 71 is blocked by the float 94 between the extension portions 92a and 92b as described above. I can't see the light.

  As a result, the seated user can recognize that the cleaning liquid remains in the cleaning liquid holding unit 5 when light is visible from the viewing window 62, and the cleaning liquid holding section when no light is visible from the viewing window 62. 5 can recognize that no cleaning liquid remains.

  Next, attachment of the cleaning liquid holding unit 5 to the local cleaning apparatus main body 1 will be described with reference to FIGS. As shown in FIG. 13, a cleaning liquid supply port 53 is opened in the cleaning liquid holding unit lid 52, and the cleaning liquid supply port lid 8 is attached to the cleaning liquid supply port 53 and closed. The cleaning liquid supply port lid 8 is provided with a rotation guide groove 81 and a knob portion 82, and the rotation guide groove 81 is rotationally mounted by sliding with a rotation guide boss 54 provided on the cleaning liquid holding portion lid 52. .

  As shown in FIGS. 14 and 15, the cleaning liquid holding section lid 52 is provided with a fixing section 55. When the cleaning liquid holding section lid 52 is attached to the local cleaning apparatus main body 1, the cleaning liquid holding section 5 of the local cleaning apparatus main body 1 is on the lower side. It is comprised so that it may mount | wear and fix to the main body guide part 15 attached to. More specifically, in this embodiment, a fixing portion 55 protruding from the lower surface of the main body guide portion 15 formed of a hole is inserted into the upper surface of the cleaning liquid holding portion lid 52 (see FIG. 14), and the cleaning liquid holding portion 5 is slid. The cleaning liquid holding unit 5 is detachably fixed to the local cleaning device main body 1 (see FIG. 15). In a state where the cleaning liquid holding unit 5 is attached to the local cleaning device main body 1, the cleaning liquid connecting portion 16 that is the upstream end of the cleaning liquid supply path 42 of the local cleaning device main body 1 is connected to the cleaning liquid path 84 of the cleaning liquid supply port lid 8. The cleaning liquid in the cleaning liquid holding part 5 is sucked up from the suction pipe 85 provided in the cleaning liquid supply port lid 8 and flows from the cleaning liquid connection part 16 to the cleaning liquid supply path 42 via the cleaning liquid path 84.

  The suction pipe 85 has a cylindrical shape, and sucks the cleaning liquid in the cleaning liquid holding part 5 from its lower end. As shown in FIG. 17, the lower end portion of the suction pipe 85 is formed with a notch so as to be inclined with respect to the longitudinal direction and its vertical surface. It becomes possible to prevent being unable to suck up the water.

  A click structure is provided between the cleaning liquid holding unit 5 and the local cleaning device main body 1 (see FIGS. 14 to 16). The click structure is configured so that when the cleaning liquid holding unit 5 is attached to the local cleaning apparatus main body 1, the position where the sealing property of the cleaning liquid connecting unit 16 is secured is notified by touch. A click feeling is generated when the click protrusion 52b protruding from the upper surface of the click protrusion 17 is provided over the protrusion 17 of the local cleaning device main body 1.

  Instead of the click structure, a detection mechanism that electrically determines that the sealing property of the cleaning liquid connecting portion 16 has been secured and prohibits the use of the function and displays it may be used. As the detection mechanism, for example, a push-type limit switch, a reed switch using a Hall element, or the like is used. When a mechanism for electrically detecting the connection state of the cleaning liquid connection unit 16 is used, a display unit for displaying the mounting state of the cleaning liquid holding unit 5 is provided.

  When the remaining amount of the cleaning liquid in the cleaning liquid holding unit 5 decreases, the user slides the cleaning liquid holding unit 5 forward (that is, from the state shown in FIG. 15 to the state shown in FIG. 14), and removes from the local cleaning device body 1 After removal, the cleaning liquid supply port lid 8 is rotated and removed. Then, after the cleaning liquid is replenished from the cleaning liquid supply port 53, the cleaning liquid holding unit 5 is attached to the local cleaning device main body 1 again.

  The cleaning liquid path 84 is composed of, for example, a tubular resin, a rubber hose, or the like, and is detachably connected to the cleaning liquid connection unit 16 provided in the local cleaning device main body 1. For example, an O-ring 86 is attached to the side of the cleaning liquid path 84 and is inserted into the cleaning liquid connection part 16 of the local cleaning apparatus main body 1 so that airtightness can be provided.

  Since the O-ring 86 is disposed on the cleaning liquid path 84 side, the O-ring 86 can be detached from the local cleaning apparatus main body 1 and can be easily replaced when the O-ring 86 is consumed.

  The cleaning liquid connecting portion 16 is mounted with a gap of, for example, about 0.3 mm between the local cleaning device body 1 and the cleaning liquid connecting portion 16. With this configuration, even when the fitting dimension between the main body guide portion 15 and the fixing portion 55 varies, the O-ring is not deformed and the sealing performance is maintained.

  Further, grease may be applied to the insertion portion of the O-ring of the cleaning liquid connection portion 16. Since the cleaning liquid connecting portion 16 is formed on the local cleaning device main body 1 side, the grease is hardly wiped off by the user, and the slidability can be maintained.

  When the cleaning liquid path 84 is removed from the cleaning liquid connection portion 16, a valve structure is provided so that the opening on the local cleaning device main body 1 side is closed (not shown). Thereby, it is possible to prevent the cleaning liquid remaining on the local cleaning apparatus main body 1 side from coming into contact with the air and to be fixed.

  In the present embodiment, the cleaning liquid holding unit 5 is configured to be attached to the lower side of the local cleaning device main body 1, but the cleaning liquid easily flows from the cleaning liquid holding unit 5 to the local cleaning device main body 1 side. It may be arranged on the upper side of the local cleaning device main body 1.

  The operation unit 2 (see FIG. 4) includes a toilet seat operation unit, a washing operation unit, and the like. The toilet seat operation part has a toilet seat temperature operation key for changing the toilet seat temperature, the washing operation part has a washing mode operation key for operating the washing mode, and a washing temperature operation for changing the temperature of the washing water A key and a cleaning flow rate operation key for changing the cleaning flow rate at the time of cleaning are arranged.

  The cleaning mode operation key includes a hot water cleaning operation key, a cleaning liquid cleaning operation key, and a bidet cleaning operation key.

  When the user performs these key operations, key input information is transmitted to the main control unit.

  As shown in FIG. 4, the local cleaning device main body 1 includes a seating sensor 17 for detecting the seating of the user and an entrance detection sensor 18 (for example, an infrared sensor or an ultrasonic wave) for detecting a person entering the toilet. Sensor).

  The irradiation means may be controlled in conjunction with the entrance detection sensor 18. For example, the irradiation unit is controlled so that the irradiation unit is turned on when the room detection sensor 18 detects that a human body has entered the room, and is automatically turned off after a predetermined time has elapsed.

  On the bottom surface of the cleaning liquid holding unit 5, a floor surface irradiation window (not shown) having light permeability may be provided. In this case, since the light irradiated from the irradiation means 9 into the cleaning liquid holding unit 5 illuminates the floor surface through the floor surface irradiation window, it is not necessary to use an indoor lighting device when going to the toilet at night.

  As cleaning modes, there are a butt cleaning and a bidet cleaning, and there are a normal warm water cleaning mode and a cleaning liquid cleaning mode in the butt cleaning.

  The operation of the component in each mode will be described.

  In the case of normal ass cleaning, bidet cleaning, toilet cleaning, and nozzle cleaning, the water supply valve 11 is opened and the water pump 14 is driven. The cleaning liquid supply pump 43 as the cleaning liquid supply means is not driven. Since the backflow prevention valve 44 is provided in the cleaning liquid supply path 42, the water flowing in from the water source does not flow into the cleaning liquid holding part 5 but flows only through the water supply path 13, and a flow path switching mechanism 35 including a rotary switching valve or the like. It is ejected from the nozzle selected in.

  When the cleaning liquid cleaning mode is selected, the water supply valve 11 is opened, the water pump 14 is driven, and the cleaning liquid supply pump 43 is driven to suck the cleaning liquid from the cleaning liquid holding unit 5. The sucked cleaning liquid passes through the cleaning liquid supply path 4 and is injected and mixed in the warm water flowing through the water supply path 13 from the cleaning liquid inlet 41. The hot water mixed with the cleaning liquid is ejected from the hip cleaning nozzle 31 to the human body part via the flow path switching mechanism 35.

  A portion of the cleaning liquid inlet 41 of the water supply path 13 is configured to have a larger cross-sectional area than other portions of the water supply path 13. As a result, the cleaning liquid is sufficiently agitated and mixed with warm water, and then ejected from the butt cleaning nozzle 31. When the water supply path 13 is not aligned before and after the cleaning liquid inlet 41, since the reflux occurs in the mixing unit, the effect of stirring is enhanced and a cleaning liquid having a uniform concentration is ejected.

  In addition to washing the buttocks in the cleaning liquid cleaning mode, the toilet switching nozzle 34 or the nozzle cleaning nozzle 33 is selected by the flow path switching mechanism 35, and the hot water mixed with the cleaning liquid from the toilet cleaning nozzle 34 or the nozzle cleaning nozzle 33 is supplied. You may squirt. In this case, higher cleaning power than normal cleaning can be expected.

  When the user enters the toilet and the entrance detection sensor 18 detects entry, the irradiation means 9 is turned on, and the user checks the liquid level in the remaining amount display window 60. The irradiation means 9 is automatically turned off after a certain time has elapsed.

  Thereafter, when the user is seated, toilet flushing is performed in conjunction with the seating. When the normal buttocks cleaning mode or bidet cleaning mode is selected after sitting, warm water is ejected from the buttocks cleaning nozzle 31 or the bidet cleaning nozzle 32 toward the human body part.

  When the cleaning liquid cleaning mode is selected, the hot water mixed with the cleaning liquid is jetted from the hip cleaning nozzle 31 to the local body part.
