That is, the control unit 160 has a connection port 180 for detachably connecting another electric device. As a result, it is possible to easily switch between the case where another electric device such as the functional water generation unit 152 is installed and the case where another electric device is not installed.

The control unit 160 includes a lighting conversion circuit 182 and a control conversion circuit 184. The lighting conversion circuit 182 converts the DC power supplied from the power supply circuit 150 into the lighting power corresponding to the lighting device 110, and supplies the lighting power to the lighting device 110.

The lighting conversion circuit 182 is, for example, a lighting power of a pulse voltage (pulse signal) of 24V that is repeatedly turned on and off at a predetermined cycle from a DC power of a substantially constant voltage of 24V supplied from the power supply circuit 150. Convert to.

The lighting conversion circuit 182 substantially detects the current flowing through the light emitting element 110a of the lighting device 110 and changes the duty ratio of the pulse voltage according to the detection result, thereby substantially causing the light emitting element 110a of the lighting device 110. Allow a constant current to flow. The lighting conversion circuit 182 is, for example, a constant current conversion circuit.

Further, the lighting conversion circuit 182 changes the duty ratio of the pulse voltage according to the operation of, for example, the display operation unit 168. Thereby, for example, the brightness of the light emitted from the lighting device 110 can be changed according to a plurality of models having different widths such as the mirror cabinet 108, the mirrors 131a to 133a, and the lighting device 110. For example, in the case of a model having a long width such as the lighting device 110, the illuminance of the light emitted from the lighting device 110 is increased, and in the case of a model having a short width such as the lighting device 110, the light emitted from the lighting device 110 is increased. The illuminance of the can be reduced.

Alternatively, the brightness of the light emitted from the lighting device 110 can be changed to the brightness desired by the user according to the operation of the display operation unit 168 or the like. In the lighting device 110, so-called dimming can be performed.

The control unit 160 is connected to the lighting switch 144. The control unit 160 turns on the lighting device 110 by supplying the lighting power of the lighting conversion circuit 182 to the lighting device 110 in response to the ON operation of the lighting switch 144. Then, the control unit 160 turns off the lighting device 110 by stopping the supply of the lighting power of the lighting conversion circuit 182 to the lighting device 110 in response to the off operation of the lighting switch 144.

The control conversion circuit 184 converts the DC power supplied from the power supply circuit 150 into the control power, and supplies the control power to each part. The control conversion circuit 184 converts, for example, 24V DC power into 5V DC control power. The control conversion circuit 184 is, for example, a step-down DC-DC converter. The DC voltage value of the control power may be any voltage value lower than the DC voltage value of the DC power supplied from the power supply circuit 150.

The control unit 160 controls these operations by, for example, supplying the DC power of 24 V supplied from the power supply circuit 150 to the functional water generation unit 152 and the solenoid valves 154, 155, and 156 as they are. Further, the control unit 160 controls the lighting of the lighting device 110 by supplying the lighting power of the pulse voltage generated by the lighting conversion circuit 182 to the lighting device 110. Then, the control unit 160 uses, for example, the 5V control power generated by the control conversion circuit 184 to the functional water irradiation unit 22, the sensor unit 24, the water leakage detection sensor 158, the temperature sensor 162, the lighting unit 164, and the attachment / detachment detection. These operations are controlled by supplying the sensor 166 and the display operation unit 168.

The sensor unit 24 is connected to the control unit 160 and inputs the detection result to the control unit 160. For the sensor unit 24, for example, an infrared distance measuring sensor having a light emitting unit and a light receiving unit is used. For the sensor unit 24, for example, a pyroelectric sensor, an ultrasonic sensor, or the like may be used. The sensor unit 24 may be any sensor that can detect a human body, a hand, or the like in a non-contact manner based on, for example, an electromagnetic wave such as infrared rays or a signal wave such as an ultrasonic wave.

The control unit 160 discharges water from the water discharge unit 12 in response to the detection of the hand by the sensor unit 24. Further, the control unit 160 stops the water discharge from the water discharge unit 12 in response to the stop of the hand detection by the sensor unit 24. As a result, as described above, automatic water discharge control is performed.

The solenoid valve 154 is connected to a hot water supply source HS such as a hot water supply pipe via a water stop valve 170. The solenoid valve 155 is connected to a water supply source MS such as a water supply pipe via a branch fitting 157 and a water stop valve 172. The solenoid valves 154 and 155 are connected to the operation unit 14. Further, the solenoid valves 154 and 155 are connected to the control unit 160. The control unit 160 controls the opening and closing of the solenoid valves 154 and 155. By opening the solenoid valves 154 and 155, the water supplied from the water supply source MS and the hot water supplied from the hot water supply source HS are supplied to the operation unit 14.

The operation unit 14 further has a flow rate adjusting valve. The operating lever 14a is connected to the flow rate adjusting valve and adjusts the opening amount of the flow rate adjusting valve. The flow rate adjusting valve adjusts the flow rates of the water supplied from the water supply source MS and the hot water supplied from the hot water supply source HS based on the valve opening amount set by the operation lever 14a. Then, the flow rate adjusting valve mixes the adjusted water and hot water and supplies the water to the water discharge unit 12. As a result, the flow rate and temperature of the water discharged from the water discharge unit 12 are adjusted.

The control unit 160 opens the solenoid valves 154 and 155 when manual water discharge is set by the automatic water discharge changeover switch 27. As a result, in the state of manual water discharge, water is discharged from the water discharge unit 12 in response to the operation of the operation unit 14.

On the other hand, when the automatic water discharge is set by the automatic water discharge changeover switch 27, the control unit 160 controls the opening and closing of the solenoid valves 154 and 155 according to the detection result of the sensor unit 24. At this time, the operation lever 14a of the operation unit 14 keeps the flow rate adjusting valve open at a predetermined flow rate. As a result, in the state of automatic water discharge, water is discharged from the water discharge unit 12 according to the detection result of the sensor unit 24.

The temperature sensor 162 is provided on the path between the water discharge unit 12 and the operation unit 14 (flow rate adjusting valve), and detects the temperature of the water discharged from the water discharge unit 12. The temperature sensor 162 is connected to the control unit 160, and the detection result is input to the control unit 160.

The control unit 160 performs the above-mentioned hot water preparation operation based on the detection result of the temperature sensor 162. When performing the hot water preparation operation, the user operates the hot water preparation switch 28 after setting the automatic water discharge, or operates the hot water preparation switch 28 and then operates the operation lever 14a of the operation unit 14 to flow the flow rate. Open the regulating valve.

The control unit 160 opens the solenoid valves 154 and 155 in response to the operation of the hot water preparation switch 28, starts water discharge from the water discharge unit 12, and then discharges water from the water discharge unit 12 based on the detection result of the temperature sensor 162. It is determined whether or not the temperature of the water discharged from the water reaches a predetermined temperature. When the control unit 160 determines that the predetermined temperature has been reached, the solenoid valves 154 and 155 are closed and the water discharge from the water discharge unit 12 is stopped. Further, the control unit 160 closes the solenoid valves 154 and 155 even when the temperature does not reach the predetermined temperature even after the lapse of a predetermined time, and stops the water discharge from the water discharge unit 12.

The solenoid valve 156 is connected to the water supply source MS via the branch fitting 157 and the water stop valve 172. The solenoid valve 156 is connected to the functional water generation unit 152. Further, the solenoid valve 156 is connected to the control unit 160. The control unit 160 controls the opening and closing of the solenoid valve 156. By opening the solenoid valve 156, the water supplied from the water supply source MS is supplied to the functional water generation unit 152.

The functional water generation unit 152 generates functional water from the water (tap water) supplied from the solenoid valve 156, and supplies the generated functional water to the functional water discharge unit 20. Further, the functional water generation unit 152 is connected to the control unit 160. The generation of functional water in the functional water generation unit 152 is controlled by the control unit 160.

The control unit 160 opens the solenoid valve 156 and operates the function water generation unit 152 in response to an input of an operation instruction from the function water operation switch 26. As a result, the functional water is discharged from the functional water discharge unit 20 to the bowl unit 122 in response to the operation of the user's functional water operation switch 26. Further, the control unit 160 lights the functional water irradiation unit 22 according to the discharge of the functional water, and illuminates the functional water discharged from the functional water discharge unit 20 as described above.

The functional water generation unit 152 has, for example, an electrolytic cell. An anode plate and a cathode plate are provided inside the electrolytic cell. The functional water generation unit 152 electrolyzes tap water and miscellaneous water flowing inside the electrolytic cell based on the signal transmitted from the control unit 160. Here, tap water contains chloride ions. Chloride ions are contained in water sources (for example, groundwater, dam water, river water, etc.) as, for example, salt (NaCl), calcium chloride (CaCl ₂ ), and the like. Therefore, hypochlorous acid is produced by electrolyzing chloride ions. As a result, the water electrolyzed in the functional water generation unit 152 (electrolyzed water) changes to a liquid containing hypochlorous acid (functional water). Hypochlorous acid functions, for example, as a deodorant component or a bactericidal component. The liquid containing hypochlorous acid can reduce general bacteria and the like.

The functional water generation unit 152 of the present embodiment is not limited to producing a liquid containing hypochlorous acid. The functional water generated by the functional water generation unit 152 may be a liquid containing metal ions such as silver ions and copper ions. Alternatively, the functional water generated by the functional water generation unit 152 may be a liquid containing electrolytic chlorine, ozone, or the like. Alternatively, the functional water generated by the functional water generation unit 152 may be acidic water or alkaline water. Further, the functional water generation unit 152 is not limited to the electrolytic cell unit having the electrolytic cell, the anode plate, and the cathode plate.

The lighting unit 164 is provided in, for example, the shelf unit 16. The shelf 16 has a light transmitting window 46 (see FIG. 2B). The light transmitting window 46 is provided on the bottom surface 16c of the shelf portion 16. The illumination unit 164 is arranged in the shelf unit 16 so as to face the light transmission window 46, and irradiates the outside of the shelf unit 16 with light through the light transmission window 46. The light transmitting window 46 has, for example, light transmission and light diffusivity with respect to the light (visible light) emitted by the illumination unit 164.

The light transmitting window 46 emits the light of the lighting unit 164 provided in the non-light transmitting shelf portion 16 to the outside of the shelf portion 16 and closes the opening provided in the bottom surface 16c of the shelf portion 16. As a result, even when the lighting unit 164 is provided in the shelf unit 16, it is possible to suppress the intrusion of water into the shelf unit 16. For example, it is possible to suppress the deterioration of the aesthetic appearance of the faucet device 10. For the light transmitting window 46, for example, a translucent (milky white) resin material is used. In other words, the light transmitting window 46 is a light diffusing plate.

The illumination unit 164 illuminates the area vertically below the shelf unit 16 by irradiating the light downward and transmitting the light through the light transmission window 46. As described above, the illumination unit 164 is provided on the shelf unit 16 and illuminates the region vertically below the shelf unit 16 by irradiating light downward from the shelf unit 16. In other words, the lighting unit 164 illuminates the area directly below the shelf unit 16. The area vertically below the shelf 16 is illuminated by the illumination unit 164.

The lighting unit 164 illuminates the area vertically below the shelf unit 16 to make the area around the water discharge unit 12 and the water discharged from the water discharge unit 12 brighter than when the lights are turned off. In other words, the water discharge unit 12 discharges water to a position illuminated by the light of the illumination unit 164. The water discharge unit 12 discharges water to a region below the shelf unit 16 illuminated by the illumination unit 164. The water discharge unit 12 discharges water to a position of the bowl unit 122 illuminated by the light of the illumination unit 164, for example. Further, at least a part of the detection range of the sensor unit 24 is provided at a position below the shelf unit 16 and illuminated by the light from the illumination unit 164. As a result, even when the space where the bathroom vanity 100 is installed is dark, such as at night, the water discharged from the water discharge unit 12 and the water discharge unit 12 can be easily visually recognized, and the usability can be improved.

The number of the illumination unit 164 and the light transmitting window 46 is not limited to one, and may be two or more. That is, the faucet device 10 may have a plurality of illumination units 164 and a plurality of light transmission windows 46. Further, the light transmitting window 46 is provided as needed and can be omitted. For example, the lighting unit 164 may be attached to the outer surface of the shelf unit 16. The mounting position of the lighting unit 164 is not limited to the above, and may be any position capable of illuminating the area vertically below the shelf unit 16.

The attachment / detachment detection sensor 166 detects attachment / detachment of the water discharge portion 12 to the wall surface WS or the shelf portion 16. That is, the attachment / detachment detection sensor 166 detects whether the water discharge portion 12 is attached to the wall surface WS or the shelf portion 16 or the water discharge portion 12 is removed from the wall surface WS or the shelf portion 16. The attachment / detachment detection sensor 166 is connected to the control unit 160, and the detection result is input to the control unit 160.

When the attachment / detachment detection sensor 166 detects that the water discharge unit 12 has been removed, the control unit 160 turns off the automatic water discharge function by the sensor unit 24. As a result, when the water discharge unit 12 is removed from the wall surface WS or the shelf unit 16 and used, it reacts to the hand holding the water discharge unit 12 and suppresses the unintentional discharge of water from the water discharge unit 12. Can be done. The attachment / detachment detection sensor 166 may be any switch or sensor capable of detecting attachment / detachment of the water discharge unit 12, such as a mechanical switch, an optical sensor, or a magnetic sensor.

The leak detection sensor 158 detects a leak in the lower cabinet 106. The leak detection sensor 158 is connected to the control unit 160, and the detection result is input to the control unit 160. When the water leakage is detected by the water leakage detection sensor 158, the control unit 160 notifies the user or the like of the water leakage detection by, for example, the display operation unit 168 or the like.

As described above, in the vanity 100 according to the present embodiment, electric power is supplied to the lighting device 110 and another electric device only by connecting another electric device such as the functional water generation unit 152 to the power supply circuit 150. Can be supplied. Even if the outlet provided in the building frame is a single bite or directly connected wiring, it is possible to eliminate the need for additional power supply work or work for branching the wiring path of the commercial power supply PS. This facilitates the construction work and reduces the time and cost required for the construction. Therefore, it corresponds to the case where the electric equipment is installed and the case where it is not installed without the need for adding a branch point to the wiring path of the AC power supplied from the commercial power supply PS or power supply work to the building frame. It is possible to provide a bathroom vanity 100 that can be used.

When the power supply circuit 150 capable of supplying DC power to the lighting device 110 and another electric device is used, the power supply circuit 150 may be relatively larger than, for example, a power supply circuit that supplies DC power only to the lighting device 110. Therefore, for example, if such a power supply circuit 150 is provided in the lighting device 110, the size of the lighting device 110 may increase. On the other hand, in the bathroom vanity 100, the power supply circuit 150 is housed in the lower cabinet 106. As a result, the size of the lighting device 110 and the like can be kept compact even when the power supply circuit 150 capable of supplying DC power to the lighting device 110 and another electric device is used.

Further, in the vanity 100, even when the wiring length from the power supply circuit 150 to the lighting device 110 becomes long, a control unit 160 is provided as a relay unit between the power supply circuit 150 and the lighting device 110 to control the vanity. By generating the electric power for lighting in the unit 160, it is possible to suppress the attenuation of the electric power due to the wiring length and to light the lighting device 110 with an appropriate amount of light.

For example, when the lighting power of the pulse voltage is supplied to the lighting device 110 as described above, if the length of the wiring for supplying the lighting power becomes long, the high frequency noise caused by the pulse voltage adversely affects other devices. There is a possibility of giving. Therefore, it becomes necessary to use an expensive shielded cable for the wiring to be supplied to the electric power for lighting, which may lead to an increase in the cost of the bathroom vanity 100. Alternatively, it becomes necessary to mount a component (for example, a filter circuit, a ferrite core, etc.) for absorbing high-frequency noise on the substrate of the control unit 160 or the lighting device 110, which increases the cost or size of the control unit 160 or the lighting device 110. May be invited.

On the other hand, by providing the control unit 160 between the power supply circuit 150 and the lighting device 110, the lighting power is supplied as compared with the case where the lighting power is directly supplied from the power supply circuit 150 to the lighting device 110. The length of the wiring can be made relatively short. As a result, it is possible to prevent high-frequency noise caused by the pulse voltage from adversely affecting other devices. For example, it is not necessary to use a shielded cable or a component for absorbing high frequency noise, and it is possible to suppress cost increase and size increase.

In the above embodiment, the control unit 160 is shown as an example of the relay unit, but the relay unit may be provided separately from the control unit 160. The relay unit may be any member provided between the power supply circuit 150 and the lighting device 110 and having at least the lighting conversion circuit 182.

Further, the bathroom vanity 100 can be further provided with service outlets 142 and 146 to further enhance the convenience of the bathroom vanity 100. Further, the service outlets 142 and 146 are provided between the connection portion 140 and the power supply circuit 150, and the AC power of the commercial power supply PS is supplied to the power supply circuit 150 via the service outlets 142 and 146 to supply the AC power of the commercial power supply PS to the service outlets 142 and 146. Even in the case of providing the above, it is possible to eliminate the need for additional power supply work or work for branching the wiring path of the commercial power supply PS.
