[0001] SUMMARY OF THE DISCLOSURE Aspects of the present invention generally relate to a vanity unit. [Background technology]

[0002] A configuration is known that detects a user in front of a washstand and controls the lighting provided on the washstand. For example, in Patent Document 1, when a change from a non-presence state in which a person is not present in front of the washstand to a presence state in which a person is present is detected, a lower lighting provided at the bottom end of the mirror is switched to a lit state. Furthermore, in Patent Document 1, when a predetermined time has passed without detecting a change from a presence state to an absence state, if the set value is ON, an upper lighting provided above the mirror is switched to a lit state, and if the set value is OFF, the upper lighting is kept off.

[0003] If the upper lighting is turned on only when a user has been present for a certain period of time, the user may feel dazzled when the upper lighting is turned on. On the other hand, if the upper lighting is set not to be turned on, the user may have difficulty seeing the washbasin unit or its surroundings (such as the mirror or his / her hands).

[0004] [Patent Document 1] JP 2020-146075 A Summary of the Invention [Problem to be solved by the invention]

[0005] The present invention has been made based on the recognition of such problems, and has an object to provide a washbasin unit that can improve usability. [Means for solving the problem]

[0006] The first invention is a washbasin unit having a mirror section, a water outlet section, and a bowl section that receives water ejected from the water outlet section, and is equipped with an acquisition section that acquires entry detection information indicating that a user has entered the space in which the washbasin unit is installed, a first lighting means that irradiates light toward the bowl section, a second lighting means that irradiates light toward the space in front of the mirror section, and a control section that controls the first lighting means and the second lighting means, wherein the control section receives a signal corresponding to the entry detection information acquired by the acquisition section, and if there is any operation on the water outlet section within a first predetermined time from the time the user entered the room, keeps the first lighting means on while keeping the second lighting means off, and if there is no operation on the water outlet section within the first predetermined time from the time the user entered the room, turns on the second lighting means.

[0007] According to this washbasin unit, the second lighting means is controlled to be turned on and off based on whether the water discharger is being used. When the water discharger is operated, the first lighting means is turned on while the second lighting means is kept off. This makes it possible to reduce glare. When the water discharger is not operated, the second lighting means is turned on. This makes it easier to see the washbasin unit or its surroundings (such as the mirror or your hands). Therefore, it is possible to provide a washbasin unit that can improve usability.

[0008] A second invention is a washbasin unit according to the first invention, characterized in that the control unit controls the lighting state of the first lighting means according to the water discharge mode of the water discharge unit.

[0009] According to this washbasin unit, by changing the control content of the first lighting means depending on the difference in the water discharge mode of the water discharger, it is possible to provide lighting suited to the usage scene of the user.

[0010] The third invention is a washbasin unit in which, in the second invention, a faucet device including the water outlet section is capable of executing an automatic water outlet mode in which water is discharged from the water outlet section based on the detection results of an object detection sensor that detects an object near the outlet of the water outlet section, and a continuous water outlet mode in which water continues to be discharged from the water outlet section until the user performs a specified operation, and the control section is capable of controlling the first lighting means to turn on in a first lighting state, and to turn on in a second lighting state having a higher color temperature and / or illuminance than in the first lighting state, and when the continuous water discharge mode is selected, the first lighting means is turned on in the second lighting state.

[0011] According to this washbasin unit, for example, when a user requires continuous water discharge, the first lighting means can be turned on with a high color temperature and / or illuminance to improve visibility, thereby further improving usability.

[0012] A fourth invention is a washbasin unit in which, in the second invention, the control unit is capable of executing control to turn on the first lighting means in a first lighting state and control to turn on the first lighting means in a second lighting state having a higher color temperature and / or illuminance than the first lighting state, and is characterized in that when the flow rate of water discharged from the water outlet is greater than or equal to a predetermined amount, the first lighting means is turned on in the second lighting state.

[0013] According to this washbasin unit, for example, when a user needs water to be discharged at a flow rate greater than a predetermined amount, the first lighting means is turned on with a high color temperature and / or illuminance, thereby improving visibility, thereby making it easier to use.

[0014] A fifth invention is a washbasin unit characterized in that, in any one of the first to fourth inventions, the acquisition unit is capable of acquiring exit detection information indicating that the user has left the space, and the control unit turns on the second lighting means when the user's exit is not detected even after a second predetermined time has elapsed since the water stop operation was performed on the water outlet unit.

[0015] According to this washbasin unit, if the user's departure is not detected and the water discharger has not been used for a predetermined period of time, the second lighting means is turned on, making it easier to see the washbasin unit or its surroundings (such as the mirror or hand area).

[0016] A sixth invention is a washbasin unit characterized in that, in any one of the first to fourth inventions, the acquisition unit is capable of acquiring exit detection information indicating that the user has left the space, and the control unit turns on the second lighting means when an operation on the mirror unit is detected between the time when a water stop operation is performed on the water outlet unit and the time when the user's exit is detected.

[0017] According to this washing unit, when a user operates the mirror portion, the second illumination means is turned on, making it easier to see the washing unit or its surroundings (the mirror portion or hands, etc.). Effect of the Invention

[0018] According to an aspect of the present invention, a washbasin unit that can improve usability is provided. [Brief description of the drawings]

[0020] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same components are designated by the same reference numerals and detailed description thereof will be omitted as appropriate. FIG. 1 is a schematic front view illustrating a washing unit according to an embodiment. FIG. 2 is a schematic side view illustrating the washing unit according to the embodiment. The washbasin unit 10 according to the embodiment includes a water outlet unit 41, a mirror unit 34, and a bowl unit 22. In this example, the washbasin unit 10 is a washbasin vanity unit including a washbasin 12, a water faucet device 14, a support base 16, and a mirror cabinet 18.

[0021] Although a vanity unit will be described as an example of the washbasin unit according to the embodiment, the washbasin unit is not limited to a vanity unit and may have at least a water outlet unit, a mirror unit, and a bowl unit. The washbasin unit according to the embodiment may be applied to, for example, washbasin equipment provided in a toilet room of a public facility.

[0022] In addition, in this specification, the terms "upper", "lower", "right", and "left" refer to upper, lower, right, and left, respectively, based on a person standing in front of the washbasin unit 10 and looking at the washbasin unit 10. In this specification, the direction from the washbasin unit 10 to the person standing in front of the washbasin unit 10 is defined as the "front" direction, and the opposite direction is defined as the "rear" direction.

[0023] The washbasin 12 has a counter portion 21, a bowl portion 22, and a back guard portion 24. The bowl portion 22 is formed in a concave shape that is recessed downward. The bowl portion 22 receives water discharged from the water discharge portion 41. The water from the water discharge portion 41 is discharged from a drain outlet provided at the bottom of the bowl portion 22 to a drain pipe.

[0024] The counter portion 21 is located on both the left and right sides, the front and the rear, of the bowl portion 22. In other words, the counter portion 21 surrounds the bowl portion 22 on the front side of the back guard portion 24. The upper surface of the counter portion 21 is, for example, a horizontal plane extending horizontally from the upper end of the bowl portion 22.

[0025] The back guard portion 24 extends upward from the rear end of the bowl portion 22 or the counter portion 21. The back guard portion 24 is provided as necessary and can be omitted. The shape of the washbasin 12 may be any shape having at least the bowl portion 22.

[0026] The support base 16 is placed on the floor of a building structure. For example, the support base 16 is placed on the floor of a space (a room such as a washroom or a dressing room) in which the washbasin unit 10 is installed. The washbasin 12 is provided on the support base 16. The support base 16 supports the washbasin 12.

[0027] 1, for the sake of convenience, a part of the washbasin unit 10 (hot water supply passage 90, water supply passage 91, water supply passage 96, flow path 94, solenoid valve 80, solenoid valve 81, solenoid valve 86, flow rate adjustment unit 44, first controller 71, etc.) is shown diagrammatically within the support base 16. However, these may be disposed within the support base 16, but are not necessarily required to be disposed within the support base 16.

[0028] The support base 16 may have, for example, a drawer or a door and function as a cabinet capable of storing items inside. The washbasin 12 may also be attached directly to a wall of a building structure (for example, a wall surface of a washroom or a dressing room). In other words, the support base 16 is provided as necessary and may be omitted.

[0029] The mirror cabinet 18 is placed above the washbasin 12 and the faucet device 14. The mirror cabinet 18 has a cabinet 30 and a mirror section 34. In this example, the mirror section 34 is three mirror doors. A mirror (mirror surface) is provided on the front of each mirror door. Note that in the embodiment, the mirror section 34 does not have to be a mirror door, and may have a mirror surface.

[0030] The mirror cabinet 18 is attached to a support such as a wall of a building structure by a fixing member such as a bolt. However, the mirror cabinet 18 may be attached to and supported by a support other than a wall (for example, a counter or panel provided separately, or the support stand 16, etc.).

[0031] The water faucet device 14 has a water discharge section 41 that discharges water toward the bowl section 22. For example, a discharge section 42 (one example of a water discharge section 41) is provided above the bowl section 22. The discharge section 42 is a so-called spout that has a water outlet. Note that the water discharged from the water discharge section 41 (for example, the discharge section 42) includes not only cold water but also heated hot water.

[0032] In this example, the discharge part 42 is located below the mirror part 34, and is attached to the counter part 21 so as to protrude upward from the upper surface of the counter part 21. The discharge part 42 is connected to a flexible hose, and at least a part of the discharge part 42 (for example, the tip part where the water outlet is provided) may be removable from the installation location of the discharge part 42 (the counter part 21 in this example).

[0033] As shown in FIG. 1, the water faucet device 14 may have a hot water supply passage 90 (hot water supply pipe) connected to a hot water supply source, and a water supply passage 91 (water supply pipe) connected to a water supply source. The hot water supply passage 90 and the water supply passage 91 join at a junction 93. The hot water supply passage 90 and the water supply passage 91 are each connected to a flow path 94 downstream of the junction 93. The flow path 94 connects the junction 93 to the discharge portion 42. Hot water from the hot water supply source is discharged from the discharge portion 42 via the hot water supply passage 90, the junction 93, and the flow path 94. Water from the water supply source is discharged from the discharge portion 42 via the water supply passage 91, the junction 93, and the flow path 94.

[0034] The water faucet device 14 has a solenoid valve 80 and a solenoid valve 81. The solenoid valve 80 is provided in the hot water supply path 90 upstream of the junction 93, and opens and closes the hot water supply path 90. The solenoid valve 81 is provided in the water supply path 91 upstream of the junction 93, and opens and closes the water supply path 91.

[0035] The water faucet device 14 may have a flow rate detection means 83 that detects the flow rate of water flowing through the flow path. The flow rate detection means 83 is, for example, a flow rate sensor (flow meter) that can detect the flow rate (liters / minute) of the flow path that supplies hot and cold water (hot water or cold water) to the water discharger 41. The detection method is not particularly limited, and a known method such as an ultrasonic method or an impeller method can be used as appropriate.

[0036] 1, the flow rate detection means 83 is provided in the water supply passage 91 upstream of the junction 93, and detects the flow rate of the water supply passage 91. Without being limited to this, the flow rate detection means 83 may be provided in a flow passage 94 downstream of the junction 93, and detect the flow rate in the flow passage 94. For example, the flow rate detection means 83 may detect the flow rate of water discharged from the water discharger 41 (e.g., the discharge portion 42).

[0037] The water faucet device 14 may be provided with a flow rate adjustment unit 44 (flow rate adjustment means). The flow rate adjustment unit 44 adjusts the flow rate of water discharged from the discharge unit 42. The flow rate adjustment unit 44 may also be capable of adjusting the temperature of the water discharged from the discharge unit 42. For example, the flow rate adjustment unit 44 has a flow rate adjustment lever 44a. The flow rate adjustment unit 44 adjusts the flow rate and temperature of the water discharged from the discharge unit 42 in response to the user's operation of the flow rate adjustment lever 44a.

[0038] The flow rate adjustment lever 44a may be attached to the discharge portion 42, for example. That is, the discharge portion 42 may be, for example, a single-lever mixer faucet. For example, the flow rate adjustment lever 44a is supported on a shaft so as to be swingable in the vertical and horizontal directions. For example, by swinging the flow rate adjustment lever 44a in the vertical direction, the flow rate of water discharged from the discharge portion 42 is adjusted, and by swinging the flow rate adjustment lever 44a in the horizontal direction, the temperature of the water discharged from the discharge portion 42 is adjusted. The manner of adjusting the flow rate and temperature in the flow rate adjustment portion 44 is not limited to the flow rate adjustment lever 44a, and any manner capable of adjusting the flow rate and temperature may be used.

[0039] The discharge part 42 is connected to the hot water supply passage 90 and the water supply passage 91 through a hot water / cold water mixing part or the like in the internal space of the support base 16 or the like. For example, the flow rate adjustment part 44 has a flow rate adjustment valve 44b provided at the junction 93. The flow rate adjustment lever 44a is connected to the flow rate adjustment valve 44b and adjusts the valve opening amount of the flow rate adjustment valve 44b. The flow rate adjustment valve 44b adjusts the respective flow rates of the water supplied from the water supply source and the hot water supplied from the hot water supply source based on the valve opening amount set by the flow rate adjustment lever 44a. Then, the flow rate adjustment valve 44b mixes the water and the hot water after the flow rate adjustment and supplies them to the discharge part 42. This adjusts the flow rate and temperature of the water discharged from the discharge part 42. It is sufficient that the flow rate adjustment part 44 is capable of at least adjusting the flow rate of the water discharged from the discharge part 42. The temperature adjustment of the water discharged from the discharge part 42 may be performed by an adjustment part other than the flow rate adjustment part 44.

[0040] The water faucet device 14 may further include a functional water discharge section 52 (another example of the water discharge section 41) that discharges functional water having a sterilizing effect. The functional water discharge section 52 is located above the bowl section 22, and discharges the functional water toward the bowl section 22 below.

[0041] In the faucet device 14, for example, by discharging functional water from the functional water discharge unit 52 into the bowl portion 22, it is possible to suppress the growth of bacteria in the drain outlet of the bowl portion 22 and inside the drain outlet. In the washbasin unit 10 and the faucet device 14, for example, it is possible to sterilize the drain outlet and the inside of the drain outlet and keep the washbasin 12 clean. In addition, it is possible to sterilize toothbrushes, cups, etc. by discharging functional water onto them. For example, the functional water discharge unit 52 sprays the functional water into the bowl portion 22 in the form of a mist.

[0042] 1, the water faucet device 14 further includes a water supply passage 96, a functional water production unit 88, and a solenoid valve 86. The water supply passage 91 branches into a water supply passage 96 at a branch point 95 upstream of the solenoid valve 81. The water supply passage 96 connects the branch point 95 and the functional water discharge unit 52. The functional water production unit 88 and the solenoid valve 86 are provided on the flow path of the water supply passage 96. The solenoid valve 86 opens and closes the water supply passage 96. The functional water production unit 88 produces functional water from water (tap water) supplied by the water supply passage 96, and supplies the produced functional water to the functional water discharge unit 52.

[0043] The washbasin unit 10 has a first lighting means L1 that irradiates light toward the bowl portion 22. Irradiating light toward the bowl portion 22 is not limited to emitting light directly toward the bowl portion 22, but also includes a case where at least a part of the emitted light is indirectly (for example, reflected) directed toward the bowl portion 22. The periphery of the bowl portion 22 is illuminated by the first lighting means L1.

[0044] The first lighting means L1 is, for example, indirect lighting. The first lighting means L1 is hidden from the front side of the washbasin unit 10 by a light shielding object. In other words, the first lighting means L1 does not need to be directly visible to a user standing upright in front of the washbasin unit 10 (for example, a user of about the average height of a Japanese adult).

[0045] Specifically, in this example, at least one of the under-mirror lighting unit L1a and the counter lighting unit L1b is provided. The under-mirror lighting unit L1a and the counter lighting unit L1b are each an example of the first lighting means L1. That is, the first lighting means L1 is, for example, either the under-mirror lighting unit L1a or the counter lighting unit L1b.

[0046] The under-mirror lighting unit L1a and the counter lighting unit L1b are each a lighting device including a light source such as an LED (light-emitting diode) or a fluorescent lamp. The lighting device may include a light-transmitting cover that covers the light source. The light-transmitting cover covers, for example, the lower part of the light source. The light-transmitting cover is not limited to being transparent, and may be translucent.

[0047] The under-mirror lighting unit L1a is located, for example, behind the lower part of the mirror section 34 and disposed inside the mirror cabinet 18. The front, sides and top of the under-mirror lighting unit L1a are covered by the mirror section 34 and the mirror cabinet 18, which are light-shielding objects. The mirror cabinet 18 is open below the under-mirror lighting unit L1a. This allows the under-mirror lighting unit L1a to irradiate light toward the bowl section 22 below, as light A1a shown in FIG. 2.

[0048] The counter lighting unit L1b is located, for example, behind the back guard section 24 and above the counter section 21. The front of the counter lighting unit L1b is covered by the back guard section 24, which is a light-shielding object. For example, at least a part of the counter section 21 is made of a light-transmitting material. This allows the light irradiated from the counter lighting unit L1b toward the counter section 21 below to travel inside the light-transmitting counter section 21. The counter section 21 is also provided with a reflecting section 21r (see FIG. 2), such as a mirror. The reflecting section 21r reflects the light from the counter lighting unit L1b above toward the bowl section 22 in front. This allows the counter lighting unit L1b to indirectly irradiate light toward the bowl section 22, like the light A1b shown in FIG. 2.

[0049] The washbasin unit 10 further includes a second lighting means L2 that irradiates light toward the space in front of the mirror unit 34. The second lighting means L2 is a light that illuminates the mirror surface of the mirror unit 34 and a user standing in front of the mirror unit 34. A portion of the light emitted by the second lighting means L2 may be directed directly toward the space in front of the mirror unit 34.

[0050] The second lighting means L2 is, for example, direct lighting. The second lighting means L2 is exposed to at least one of the lower side and the front side of the washbasin unit 10. That is, the first lighting means L1 can be seen directly by a user standing upright in front of the washbasin unit 10 (for example, a user of about the average height of a Japanese adult).

[0051] Specifically, in this example, an on-mirror lighting unit L2a is provided. The on-mirror lighting unit L2a is an example of the second lighting means L2. The on-mirror lighting unit L2a is a lighting device including a light source such as an LED or a fluorescent lamp.

[0052] The mirror lighting unit L2a is located above the mirror section 34. At least a part of the lower part of the mirror lighting unit L2a does not need to be covered by a light shielding material. The mirror lighting unit L2a can directly irradiate light to the lower mirror section 34 and the space in front of the mirror section 34, as shown in FIG. 2 by light A2.

[0053] The washbasin unit 10 has a control unit 70. The control unit 70 controls the first lighting means L1 and the second lighting means L2. For example, the control unit 70 controls the on / off, brightness (illuminance or luminance), and color temperature of the first lighting means L1 and the second lighting means L2. The control unit 70 also controls the faucet device 14. For example, the control unit 70 controls the temperature of the water discharged from the discharge unit 42, controls the discharge and stopping of water from the discharge unit 42, and controls the discharge and stopping of water from the functional water discharge unit 52.

[0054] In this example, the control unit 70 has a first controller 71 on the sink side and a second controller 72 on the mirror side. The first controller 71 is provided, for example, inside the support base 16. The second controller 72 is provided, for example, inside the mirror cabinet 18.

[0055] The first controller 71 includes an electric circuit that controls the operation of the counter lighting unit L1b and the faucet device 14. The second controller 72 includes, for example, an electric circuit that controls the operation of the under-mirror lighting unit L1a and the above-mirror lighting unit L2a.

[0056] 1, the washbasin unit 10 has an operation unit 63 and an operation unit 64. The operation unit 63 and the operation unit 64 are sensors, switches, or the like that allow a user to control the operation (function) of the washbasin unit 10. When the operation unit 63 and the operation unit 64 receive an operation input, an operation signal corresponding to the operation input is transmitted to the control unit 70. When the control unit 70 receives the operation signal, it controls the operation (function) corresponding to the operation signal.

[0057] For example, the operation unit 63 is a detection sensor that allows the user to input an operation to control the discharge and stopping of water from the discharge unit 42. In this example, the operation unit 63 is provided at the bottom of the mirror cabinet 18, and is capable of detecting an object (for example, the user's hand) present in the detection area B. The detection area B is an area set around the discharge unit 42, and is a portion of the space in front of the back guard unit 24. The operation unit 63 detects the user's hand that is placed in the detection area B. The user performs an operation input to the operation unit 63 by placing their hand over the operation unit 63 (i.e., by placing their hand in the detection area B). The control unit 70 controls the discharge and stopping of water from the discharge unit 42 of the faucet device 14 in accordance with the operation input received by the operation unit 63.

[0058] For example, the operation unit 64 is a detection sensor that allows the user to input an operation to control the functional water discharge unit 52 to discharge and stop water. In this example, the operation unit 64 is provided at the bottom of the mirror cabinet 18 and can detect an object (for example, the user's hand) present in the detection area F. The detection area F is an area set around the functional water discharge unit 52 and is a portion of the space in front of the back guard unit 24. The operation unit 64 detects the user's hand that is placed in the detection area F. The user performs an operation input to the operation unit 64 by holding their hand over the operation unit 64 (i.e., by placing their hand in the detection area F). The control unit 70 controls the functional water discharge unit 52 of the faucet device 14 to discharge and stop water in accordance with the operation input received by the operation unit 64.

[0059] More specifically, a microwave sensor, a millimeter wave sensor, an infrared (photoelectric) sensor, an ultrasonic sensor, or the like can be used for the operation units 63 and 64. Furthermore, the operation units 63 and 64 are not limited to devices that perform operation input in a non-contact manner, and may be devices that allow operation input by contact. For example, the operation units 63 and 64 may be touch switches such as tact switches and capacitance switches.

[0060] 2, the washbasin unit 10 includes an acquisition unit 60. The acquisition unit 60 acquires entry detection information indicating that a user has entered the space in which the washbasin unit 10 is installed. The acquisition unit 60 can also acquire exit detection information indicating that a user has left the space in which the washbasin unit 10 is installed. The control unit 70 controls the first lighting means L1 and the second lighting means L2 based on the entry detection information and the exit detection information.

[0061] FIG. 3 is a schematic side view illustrating the washing unit according to the embodiment. 3 illustrates an example of the acquisition unit 60. In this example, the acquisition unit 60 is a detection sensor 62 capable of detecting a human body approaching the washbasin unit 10. The detection sensor 62 is a radio wave sensor such as a millimeter wave sensor that uses radio waves with a wavelength of about 1.3 mm to 4.0 mm. The detection sensor 62 is provided behind the bowl portion 22 and below the water discharge portion 41. The detection sensor 62 is disposed, for example, in the support base 16.

[0062] The detection sensor 62 detects whether or not a user is present in a detection area C in front of the washbasin unit 10. The detection area C is an area in front of the bowl portion 22. This makes it possible to suppress false detections caused by, for example, the swaying of water accumulated in the bowl portion 22. The front end of the detection area C is near the wall W1 of the space in which the washbasin unit 10 is installed. The position of the front end of the detection area C can be adjusted as appropriate depending on the size of the space in which the washbasin unit 10 is installed.

[0063] Thus, in this example, the acquisition unit 60 is an entry / exit detection sensor capable of detecting the entry of a user into a room in which the washbasin unit 10 is installed and the exit of the user from the room. In this case, the entry detection information and the exit detection information acquired by the acquisition unit 60 are the detection results of the detection sensor 62. In other words, the entry detection information is a signal indicating that a state in which the user is not present in the room has changed to a state in which the user is present in the room, and the exit detection information is a signal indicating that a state in which the user is present in the room has changed to a state in which the user is not present in the room.

[0064] The detection sensor 62 is not limited to a millimeter wave sensor, and any sensor capable of detecting a user's entry and exit can be used, such as a microwave sensor, an infrared projector type distance measuring sensor, or a pyroelectric sensor.

[0065] In the embodiment, the acquisition unit 60 is not limited to the above-mentioned detection sensor 62. For example, the acquisition unit 60 may be a door opening / closing detection sensor installed on the door of the room in which the washbasin unit 10 is installed. In this case, the entry detection information and the exit detection information are detection results (signals) indicating the open and closed states of the door. By detecting the opening and closing of the door, it is possible to estimate whether a user is present in the room. Alternatively, the acquisition unit 60 may be a communication device that receives (acquires) a signal according to the position of the user as the entry detection information (and exit detection information). More specifically, the acquisition unit 60 receives a signal from a mobile terminal such as a smartphone carried by the user. The acquisition unit 60 may be a communication module that performs short-range wireless communication with the mobile terminal. For example, the acquisition unit 60 is paired with the mobile terminal and communicates with the mobile terminal by a Bluetooth (registered trademark) signal. Note that the communication method is not limited to Bluetooth (registered trademark), and the position information may be acquired by any communication method. The entry and exit of the user may be estimated depending on whether or not the mobile terminal is connected by short-range wireless communication. In this way, the acquisition unit 60 may have any configuration capable of acquiring information indicating that a user has entered the room.

[0066] Furthermore, the washbasin unit 10 has an object detection sensor 61 that detects an object near the water outlet of the water outlet 41. In this example, the detection sensor 62, which is the acquisition unit 60, also serves as the object detection sensor 61. However, the present invention is not limited to this, and the object detection sensor 61 may be a sensor provided separately from the acquisition unit 60. The scope of the configuration including the acquisition unit 60 and the object detection sensor 61 may include a configuration in which the object detection sensor 61 is provided separately from the acquisition unit 60, or a configuration in which one sensor serves as both the acquisition unit 60 and the object detection sensor 61.

[0067] Object detection sensor 61 detects an object (e.g., a user's hand) present in detection area A below the water outlet of water spouting unit 41. For example, object detection sensor 61 detects a hand present within a radius of about 100 millimeters (mm) from the water outlet of water spouting unit 41. Object detection sensor 61 detects, for example, a user's hand held out in bowl portion 22 or above bowl portion 22. Object detection sensor 61 detects, for example, a user's hand held out between bowl portion 22 and water spouting unit 41.

[0068] The object detection sensor 61 is not limited to a radio wave sensor (millimeter wave sensor). Any sensor capable of detecting a user's hand held out to the water discharger 41, such as a microwave sensor, a pyroelectric sensor, an ultrasonic sensor, or an infrared distance measuring sensor, can be used as the object detection sensor 61. The position of the object detection sensor 61 may be any position capable of detecting a user's hand held out to the water discharger 41.

[0069] The control unit 70 controls the discharge or stopping of water from the water discharge unit 41 based on the detection result of the object detection sensor 61, i.e., whether or not an object is present near the water discharge unit 41. For example, the control unit 70 controls the opening and closing of a solenoid valve provided in a water supply path and / or a hot water supply path connected to the water discharge unit 41 based on the detection result of the object detection sensor 61.

[0070] FIG. 4 is a block diagram illustrating the washbasin unit according to the embodiment. The first controller 71 has a power supply unit 71a, a control unit 71b, and a drive unit 71c. The power supply unit 71a supplies power to the control unit 71b and the drive unit 71c. The control unit 71b and the drive unit 71c are control circuits including, for example, a microcomputer. The control unit 71b may be provided with a storage unit. The control unit 71b is communicatively connected to the detection sensor 62 (the acquisition unit 60 and the object detection sensor 61) and the flow rate detection means 83. The control unit 71b receives the detection result of the acquisition unit 60, i.e., a signal corresponding to the entry detection information and a signal corresponding to the exit detection information. The control unit 71b receives the detection result of the flow rate detection means 83.

[0071] The drive unit 71c is connected to the control unit 71b so as to be able to communicate with the counter illumination unit L1b, the solenoid valve 81, the solenoid valve 80, the solenoid valve 86, and the functional water production unit 88. The drive unit 71c receives control signals from the control unit 71b for controlling the counter illumination unit L1b, the solenoid valve 81, the solenoid valve 80, the solenoid valve 86, and the functional water production unit 88. The drive unit 71c transmits drive signals to the counter illumination unit L1b, the solenoid valve 81, the solenoid valve 80, the solenoid valve 86, and the functional water production unit 88 in response to the control signals from the control unit 71b. The counter illumination unit L1b, the solenoid valve 81, the solenoid valve 80, the solenoid valve 86, and the functional water production unit 88 each operate in response to the drive signal from the drive unit 71c.

[0072] The second controller 72 has a power supply unit 72a, a control unit 72b, and a drive unit 72c. The power supply unit 72a supplies power to the control unit 72b and the drive unit 72c. The control unit 72b and the drive unit 72c are control circuits including, for example, a microcomputer. The control unit 72b is communicatively connected to the control unit 71b. The control unit 72b is communicatively connected to the operation unit 63 and the operation unit 64. The control unit 72b receives the detection result of the operation unit 63 (detection sensor) and the detection result of the operation unit 64 (detection sensor). The control unit 72b may be connected to a time setting means 65 that sets the time. The time setting means 65 is, for example, a switch, button, or sensor operated by the user.

[0073] The drive unit 72c is connected to the control unit 72b so as to be able to communicate with each of the above-mirror lighting unit L2a and the under-mirror lighting unit L1a. The drive unit 72c receives control signals from the control unit 72b for controlling each of the above-mirror lighting unit L2a and the under-mirror lighting unit L1a. The drive unit 72c transmits drive signals to each of the above-mirror lighting unit L2a and the under-mirror lighting unit L1a in response to the control signals from the control unit 72b. Each of the above-mirror lighting unit L2a and the under-mirror lighting unit L1a operates in response to the drive signals from the drive unit 72c.

[0074] In FIG. 4, the communication connections between the components may be wired, wireless, or a combination of wired and wireless, and the communication method is not particularly limited. Furthermore, each component represented by a functional block does not necessarily have to be physically configured as illustrated. For example, the control unit 70 is provided in a distributed manner in the first controller 71 and the second controller 72, but the embodiment is not limited to this. As appropriate, some or all of the multiple functional blocks may be consolidated, or each functional block may be distributed to multiple devices communicably connected via a network. Part of each functional block may be moved to another block. Each component may be functionally or physically distributed or integrated as appropriate.

[0075] The water faucet device 14 can execute an automatic water discharge mode in which water is discharged from the water discharge portion 41 based on the detection result of the object detection sensor 61. For example, when a user holds out his / her hand in the detection area A, the object detection sensor 61 detects an object (hand) in the detection area A. Then, a signal corresponding to the detection result of the object detection sensor 61 (that an object is present in the detection area A) is transmitted to the control unit 71b. In response to the signal, the control unit 71b operates the water faucet device 14 in the automatic water discharge mode. That is, the control unit 71b opens the solenoid valve 81 and / or the solenoid valve 80. This starts the discharge of water from the discharge portion 42.

[0076] Thereafter, when the user moves his / her hand outside the detection area A, a signal corresponding to the detection result of the object detection sensor 61 (that an object is not present in the detection area A) is transmitted to the control unit 71b. In response to the signal, the control unit 71b stops water discharge in the automatic water discharge mode. That is, the control unit 71b transmits a drive signal from the drive unit 71c to close the solenoid valve 81 and / or the solenoid valve 80. This stops the discharge of water from the discharge unit 42.

[0077] Thus, in the automatic water discharge mode, when the user holds out his / her hand below the discharge portion 42, water begins to be discharged from the discharge portion 42. In the automatic water discharge mode, the control unit 70 closes the solenoid valves 80, 81 when the object detection sensor 61 does not detect the user's hand, and opens the solenoid valves 80, 81 when the object detection sensor 61 detects the user's hand. In the automatic water discharge mode, the user can discharge water while holding their hand over the device without operating the flow rate adjustment lever 44a.

[0078] The water faucet device 14 can also execute a continuous water discharge mode in which water continues to be discharged from the water discharge portion 41 until the user performs a predetermined operation. In this example, the predetermined operation is to perform an operation input to the operation portion 63. For example, when the user performs an operation input to the operation portion 63 by extending his / her hand into the detection area B, a signal corresponding to the operation input is transmitted to the control portion 72b and the control portion 71b. That is, a signal corresponding to the detection result of the operation portion 63 (that an object is present in the detection area B) is transmitted to the control portion 72b and the control portion 71b. In response to the signal, the control portion 72b and the control portion 71b operate the water faucet device 14 in the continuous water discharge mode. That is, the control portion 72b and the control portion 71b open the solenoid valve 81 and / or the solenoid valve 80. This starts the discharge of water from the discharge portion 42. In the continuous water discharge mode, even if the user moves his / her hand outside the detection area B, the solenoid valve 81 and / or the solenoid valve 80 are in the open state, and water discharge continues.

[0079] Thereafter, when the user again puts his / her hand into detection area B to perform an operation input to operation unit 63, a signal corresponding to the operation input is transmitted to control unit 72b and control unit 71b. That is, a signal corresponding to the detection result of operation unit 63 (that an object is present in detection area B) is transmitted to control unit 72b and control unit 71b. In response to the signal, control unit 72b and control unit 71b stop water discharge in the continuous water discharge mode. That is, control unit 72b and control unit 71b close solenoid valve 81 and / or solenoid valve 80. This stops the discharge of water from discharge unit 42.

[0080] In this way, in the continuous water discharge mode, for example, water discharge may be started by a first operational input by the user, and water discharge may be stopped by a second operational input.

[0081] A user can select the automatic water discharge mode by operating (waving a hand over) the object detection sensor 61, and can select the continuous water discharge mode by operating the operation unit 63.

[0082] The functional water generating unit 88 generates functional water from water (tap water) supplied from the water supply passage 96, and supplies the generated functional water to the functional water discharge unit 52. The functional water generating unit 88 has, for example, an electrolytic cell. An anode plate and a cathode plate are provided inside the electrolytic cell. The functional water generating unit 88 electrolyzes tap water or general service water flowing inside the electrolytic cell based on a signal transmitted from the control unit 70. 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) or calcium chloride (CaCl2). Therefore, hypochlorous acid is generated by electrolyzing chloride ions. As a result, the water electrolyzed in the functional water generating unit 88 (electrolyzed water) changes into a liquid (functional water) containing hypochlorous acid. Hypochlorous acid functions, for example, as a deodorizing component or a sterilizing component. The liquid containing hypochlorous acid can reduce general bacteria, etc.

[0083] The functional water generating unit 88 of this embodiment is not limited to generating a liquid containing hypochlorous acid. The functional water generated in the functional water generating unit 88 may be a liquid containing metal ions such as silver ions or copper ions. Alternatively, the functional water generated in the functional water generating unit 88 may be a liquid containing electrolytic chlorine or ozone. Alternatively, the functional water generated in the functional water generating unit 88 may be acidic water or alkaline water. Furthermore, the functional water generating unit 88 is not limited to an electrolytic cell unit having an electrolytic cell, an anode plate, and a cathode plate.

[0084] The water faucet device 14 discharges functional water from the functional water discharger 52 in response to an operational input by the user to the operation unit 64. For example, when the user performs an operational input to the operation unit 64 by placing his / her hand in the detection area F, a signal in response to the operational input is transmitted to the controllers 72b and 71b. That is, a signal in response to the detection result of the operation unit 63 (that an object is present in the detection area F) is transmitted to the controllers 72b and 71b. In response to this signal, the controllers 72b and 71b open the solenoid valve 86 and operate the functional water production unit 88. This starts the discharge of water from the functional water discharger 52.

[0085] For example, the water faucet device 14 sprays the functional water for a predetermined time (e.g., 10 seconds) and automatically stops spraying the functional water when the predetermined time has elapsed. For example, the control unit 72b and control unit 71b close the solenoid valve 86 and stop the functional water production unit 88 when a predetermined time has elapsed since the start of the discharge of the functional water. Note that the control unit 70 may, for example, cause the water faucet device 14 to start discharging the functional water in response to a first operation input to the operation unit 64, and cause the water faucet device 14 to stop discharging the functional water in response to a second operation input to the operation unit 64.

[0086] For example, when a user enters a space in which the washbasin unit 10 is installed, the acquisition unit 60 acquires entry detection information. Then, the control unit 70 (control unit 71b and / or control unit 72b) receives a signal corresponding to the entry detection information acquired by the acquisition unit 60. If the first lighting means L1 was turned off before the user entered the room, the control unit 70 turns on the first lighting means L1 upon receiving the signal corresponding to the entry detection information.

[0087] The first lighting means L1 may be turned on before the user enters the room. In this case, when the control unit 70 receives a signal corresponding to the entry detection information, the control unit 70 maintains the first lighting means L1 turned on. Before the user enters the room, the second lighting means L2 may be turned off.

[0088] A user who has entered the room may perform a task in the washbasin unit 10. An example of a task is the use of the mirror unit 34. The use of the mirror unit 34 includes, for example, looking at the mirror unit 34 when getting ready, such as styling one's hair, or applying makeup, or operating the mirror unit 34, such as opening and closing the mirror door. Without being limited to this, a task may also be thorough hand washing (e.g., rubbing hands with soap while the water discharge is stopped), brushing teeth, checking the condition of clothes, such as stains, putting items in and taking items out of the mirror cabinet, etc. A task is an action that takes a relatively long time, for example, longer than 10 seconds.

[0089] In the embodiment, the control unit 70 turns off the second lighting means L2, for example, when the user is staying in the room and not performing a task. The control unit 70 turns on the second lighting means L2, for example, when the user is staying in the room and performing a task. In this way, by controlling the on / off of the first lighting means L1 and the second lighting means L2 according to the usage scene of the user, it is possible to improve usability.

[0090] For example, if a user is in a room and the water discharge from the faucet device 14 has been stopped for longer than a predetermined time, it is presumed that the user is performing a task. If there is no operation on the water discharge unit 41 within a first predetermined time from the time the user enters the room, the control unit 70 turns on the second lighting means L2. On the other hand, if there is an operation on the water discharge unit 41 within a first predetermined time from the time the user enters the room, the control unit 70 keeps the first lighting means L1 on while keeping the second lighting means L2 off. As an example, the first predetermined time is between 2 seconds and 10 seconds, but is not particularly limited and can be determined as appropriate.

[0091] The time when the user enters the room may be the time when the detection sensor 62 detects the user, that is, the time when the acquisition unit 60 acquires the entry detection information, or the time when the control unit 70 receives a signal corresponding to the entry detection information. The operation on the water discharge unit 41 may be an operation to start water discharge from the water discharge unit 41. More specifically, in this example, the operation on the water discharge unit 41 is to put a hand in the detection area A, to put a hand in the detection area B (operation input to the operation unit 63), to put a hand in the detection area F (operation input to the operation unit 64), or to operate the flow rate adjustment lever 44a. When the control unit 70 receives a signal corresponding to such an operation, it can determine that the water discharge unit 41 has been operated, and when it does not receive a signal, it can determine that the water discharge unit 41 has not been operated. Alternatively, a flow rate detection means for detecting the flow rate of water discharged by the water discharge unit 41 may be appropriately provided, and the presence or absence of water discharge, that is, the presence or absence of operation on the water discharge unit 41 may be determined based on the detection result.

[0092] In this way, according to the washbasin unit 10 of the embodiment, the second lighting means L2 is controlled to be turned on and off based on whether the water discharger 41 is used. When the water discharger 41 is operated, the first lighting means L1 is turned on while the second lighting means L2 is kept off. This can reduce glare. For example, when a user operates the water discharger 41 at night, the second lighting means L2 does not turn on even after a predetermined time has passed, so that the user is prevented from waking up due to glare. On the other hand, when the water discharger 41 is not operated (for example, when performing a task such as using a mirror), the second lighting means L2 is turned on. This makes it easier to see the washbasin unit 10 or its surroundings (such as a mirror or hands). For example, when a user is taking a long time to perform a task such as using a mirror, the second lighting means L2 is turned on, making it easier to perform the task. Therefore, according to the embodiment, a washbasin unit that can improve usability can be provided. For example, it is possible to achieve both reduction in glare and usability.

[0093] Furthermore, when the user's departure is not detected even after a second predetermined time has elapsed since the water stop operation was performed on the water discharger 41 (i.e., the acquisition unit 60 does not acquire the exit detection information, and the control unit 70 does not receive a signal corresponding to the acquisition of the exit detection information), the control unit 70 turns on the second lighting means L2. As an example, the second predetermined time is from 5 seconds to 10 seconds, but is not particularly limited and can be determined as appropriate.

[0094] In this way, when the control unit 70 does not detect the user's departure from the room and the water discharge unit 41 has not been used for a predetermined time or longer, it turns on the second lighting means L2. This makes it easier to see the washbasin unit 10 or its surroundings (such as the mirror or hands). For example, when performing a task such as brushing teeth or thorough hand washing, the second lighting means L2 turns on, making it easier to perform the task.

[0095] The time when the water stop operation is performed on the water discharger 41 may be, for example, in the case of water discharge in the automatic water discharge mode described above, the time when the object detection sensor 61 detects that the user has moved his / her hand outside the detection area A, or the time when the control unit 70 receives the detection result. Alternatively, the time when the water stop operation is performed on the water discharger 41 may be, for example, in the case of water discharge in the continuous water discharge mode described above, the time when the detection sensor detects that the user has put his / her hand out into the detection area B (the time when the operation input to the operation unit 63 is detected), or the time when the control unit 70 receives the detection result. Alternatively, the time when the water stop operation is performed on the water discharger 41 may be the time when the control unit 70 transmits a drive signal to close the solenoid valve, the time when the water discharger 41 stops discharging water, or the time when the user operates the flow rate adjustment lever 44a to stop discharging water. For example, the time when water discharge is stopped or started can be obtained based on the detection result of a flow rate detection means that detects the flow rate of water discharged by the water discharger 41.

[0096] In addition, after the water stop operation is performed on the water outlet 41, if an operation on the mirror unit 34 is detected until the user's leaving the room is detected (for example, until the time the acquisition unit 60 acquires the exit detection information, or until the control unit 70 receives a signal corresponding to the exit detection information), the control unit 70 turns on the second lighting means L2.

[0097] When the user operates the mirror unit 34, the second lighting means L2 is turned on, making it easier to see the washbasin unit 10 or its surroundings (the mirror unit 34 or hands, etc.). This makes it easier to see the washbasin unit or its surroundings (the mirror unit or hands, etc.). For example, when the user does not use the washbasin vanity unit itself or uses only the mirror, the second lighting means L2 is turned on, improving usability.

[0098] The operation on the mirror unit 34 is, for example, the opening and closing of the mirror door (mirror unit 34). The opening and closing of the mirror unit 34 can be detected by providing a mirror door opening and closing detection sensor (not shown) in the mirror cabinet 18. For the opening and closing detection, a known means such as a magnetic sensor can be used, but is not particularly limited. Alternatively, the operation on the mirror unit 34 may be the use of the mirror unit 34, such as looking at an image reflected in a mirror. For example, a distance measuring sensor (not shown) may be provided, and when the distance between the user and the mirror unit 34 is shorter than a predetermined distance, it may be determined that the user is using the mirror unit 34. Without being limited thereto, it may be determined that the user is using the mirror unit 34 by analyzing the position and posture of the user from an image acquired by a camera (not shown), for example.

[0099] FIG. 5 is a flowchart illustrating the operation of the washing unit according to the embodiment. The control unit 70 starts automatic lighting control of the first lighting means L1 and the second lighting means L2 (step S101). For example, when a user enters a space in which the washing unit 10 is installed, the detection sensor 62 detects the presence of the user in the detection area C (step S102). That is, the acquisition unit 60 acquires entry detection information.

[0100] When the acquisition unit 60 acquires the entry detection information, the control unit 70 (control unit 71b and / or control unit 72b) turns on the under-mirror lighting unit L1a or the counter lighting unit L1b (step S103). That is, the control unit 70 turns on the first lighting means L1.

[0101] Thereafter, if an operation is performed on the water discharger 41 (step S105: YES) before a predetermined time has elapsed (step S104) (within the predetermined time), the control unit 70 keeps the under-mirror lighting unit L1a or the counter lighting unit L1b on (step S106). That is, the control unit 70 keeps the first lighting means L1 on. At this time, as described above, the control unit 70 keeps the second lighting means L2 off. This makes it possible to reduce, for example, glare. Then, the water stop operation of the water discharger 41 is performed (step S107).

[0102] If the user's departure is detected within a predetermined time (step S108) after the water stop operation is performed, that is, if the user's presence in the detection area C is not detected after the predetermined time (step S109: YES), the control unit 70 turns off the under-mirror lighting unit L1a or the counter lighting unit L1b (step S110).The automatic lighting control ends (step S111).

[0103] On the other hand, if there is no operation on the water discharger 41 (step S105: NO) from the time the user enters the room until a predetermined time has elapsed (step S104) (within the predetermined time), the control unit 70 turns on the mirror lighting unit L2a (step S112). That is, as described above, if there is no operation on the water discharger 41 within a predetermined time from the time the user enters the room, the control unit 70 turns on the second lighting means L2. This can improve visibility of the washbasin unit or its surroundings (such as the mirror or hands).

[0104] Furthermore, if the user's departure is not detected (within a predetermined time) after the water stop operation is performed until a predetermined time has elapsed (step S108), i.e., if the presence of a user in the detection area C is detected after a predetermined time has elapsed (step S109: NO), the control unit 70 turns on the mirror lighting unit L2a (step S112). That is, as described above, if the user's departure is not detected even after a predetermined time has elapsed after the water stop operation is performed, the control unit 70 turns on the second lighting means L2. This improves the visibility of the washbasin unit 10 or its surroundings, improving usability.

[0105] When turning on the second illumination means L2 in step S112, the control unit 70 may keep the first illumination means L1 turned on, or may turn off the first illumination means L1.

[0106] Thereafter, if the user's departure is detected, i.e., for example, if the presence of the user in the detection area C is not detected (step S113: YES), the control unit 70 turns off the mirror-mounted lighting unit L2a (step S114). At this time, if the first lighting means L1 is on, the control unit 70 may also turn off the first lighting means L1, or may keep the first lighting means L1 on. The automatic lighting control ends (step S115). On the other hand, if the user's departure is not detected (step S113: NO), the mirror-mounted lighting unit L2a is kept on.

[0107] Incidentally, when turning on the first lighting means L1, the control unit 70 may control the lighting state of the first lighting means L1 according to the water discharge mode of the water discharger 41, such as the automatic water discharge mode and the continuous water discharge mode. By changing the control content of the first lighting means L1 according to the difference in the water discharge mode of the water discharger 41, it is possible to provide lighting that is suited to the usage scene of the user.

[0108] The control of the lighting state of the first lighting means L1 is, for example, a control of at least one of the color temperature and the illuminance (for example, the brightness on the surface of the counter section 21 or the bowl section 22). For example, the control unit 70 can execute a control to light the first lighting means L1 in the first lighting state and a control to light the first lighting means L1 in the second lighting state. The first lighting means L1 is lighted at a predetermined illuminance and / or color temperature in each of the first lighting state and the second lighting state. The second lighting state has at least one of a color temperature higher than the color temperature of the first lighting state and an illuminance higher than the illuminance of the first lighting state. That is, for example, the color temperature in the second lighting state is higher than the color temperature in the first lighting state. For example, the illuminance in the second lighting state is higher than the illuminance in the first lighting state.

[0109] As an example, the illuminance in the first lighting state is about 40-60% of the maximum illuminance of the first lighting means L1, and the color temperature in the first lighting state is about 2700-3300 K. For example, the illuminance in the second lighting state is about 80-100% of the maximum illuminance of the first lighting means L1, and the color temperature in the second lighting state is about 4500-5500 K. The illuminance and / or color temperature in the first lighting state and the second lighting state may be set to different values ​​depending on the time of day, such as morning, afternoon, or night.

[0110] Note that the control of the lighting state of the first lighting means L1 is not limited to the above, and for example, when the first lighting means L1 includes a plurality of light sources, it may be control of which light source is turned on.

[0111] The water discharge mode of the water discharger 41 is, for example, a water discharge mode executed by the water faucet device 14, such as an automatic water discharge mode and a continuous water discharge mode. The water discharge mode of the water discharger 41 may also be the flow rate of water discharged by the water discharger 41. The water flow rate can be detected by a flow rate detection means (flow rate sensor). The water discharge mode of the water discharger 41 may also be the temperature of the water discharged by the water discharger 41. The water discharge mode may be the form of water discharged by the water discharger 41, such as straightened water discharge, shower water discharge, or foam water discharge. Straightened water discharge discharges water in a single water stream. Shower water discharge discharges water in multiple water streams or droplets. Foam water discharge includes air bubbles in the discharged water. Foam water discharge may be foam shower water discharge in which multiple water streams or droplets include air bubbles, or foam single water discharge in which one water stream includes air bubbles. The water discharge mode may be the properties or components of the water discharged by the water discharger 41, such as whether or not the water is functional water. In the case of a pull-out faucet in which the water discharger 41 is connected to a hose, the water discharge mode may be whether or not water is discharged when the water discharger 41 is pulled out from a predetermined installation position. The water discharge mode is not limited to the above, and may be any type of mode.

[0112] FIG. 6 is a flowchart illustrating the operation of the washing unit according to the embodiment. Fig. 6 shows the water discharge / illumination control. The water discharge / illumination control corresponds to, for example, steps S105 to S107 described with reference to Fig. 5. In the example of Fig. 6, the first illumination means L1 is an under-mirror illumination unit L1a.

[0113] The control unit 70 starts water discharge and lighting control (step S201). At this time, the control unit 70 turns on the under-mirror lighting unit L1a in the first lighting state.

[0114] The control unit 70 causes the water discharge unit 41 (e.g., the discharge unit 42) to start discharging water (step S202). If the water discharge flow rate (the flow rate of water discharged from the water discharge unit 41) is 2 L (liters) / min or more (step S203: YES), the control unit 70 changes the under-mirror lighting unit L1a from the first lighting state to the second lighting state (step S204). That is, the control unit 70 increases the illuminance and / or color temperature of the under-mirror lighting unit L1a.

[0115] Thereafter, when the water discharge flow rate becomes 0 L / min (step S205: YES), that is, when water discharge has ended (step S209), the control unit 70 ends the water discharge / illumination control (step S210).

[0116] If the water discharge flow rate is not 0 L / min (step S205: NO) and is 2 L (liters) / min or more (step S206: YES), the control unit 70 maintains the lighting of the mirror lighting unit L1a in the second lighting state (step S204).

[0117] If the water discharge flow rate is not 0 L / min (step S205: NO) and is less than 2 L / min (step S206: NO), the control unit 70 changes the under-mirror lighting unit L1a from the second lighting state to the first lighting state (step S207). That is, the control unit 70 reduces the illuminance and / or color temperature of the under-mirror lighting unit L1a.

[0118] Thereafter, if the water discharge flow rate is not 0 L / min (step S208: NO), the control unit 70 maintains the lighting of the under-mirror lighting unit L1a in the first lighting state (step S207). If the water discharge flow rate becomes 0 L / min (step S208: YES), that is, if water discharge has ended (step S209), the control unit 70 ends the water discharge / illumination control (step S210).

[0119] Furthermore, after the start of water discharge, if the water discharge flow rate is less than 2 L / min (step S203: NO), the control unit 70 maintains the lighting of the under-mirror lighting unit L1a in the first lighting state (step S211).

[0120] Thereafter, when the water discharge flow rate becomes 0 L / min (step S212: YES), that is, when water discharge has ended (step S216), the control unit 70 ends the water discharge / illumination control (step S217).

[0121] If the water discharge flow rate is not 0 L / min (step S212: NO) and is less than 2 L (liters) / min (step S213: NO), the control unit 70 maintains the lighting of the mirror lighting unit L1a in the first lighting state (step S211).

[0122] If the water discharge flow rate is not 0 L / min (step S212: NO) but is 2 L / min or more (step S213: YES), the control unit 70 changes the under-mirror lighting unit L1a from the first lighting state to the second lighting state (step S214). That is, the control unit 70 increases the illuminance and / or color temperature of the under-mirror lighting unit L1a.

[0123] Thereafter, if the water discharge flow rate is not 0 L / min (step S215: NO), the control unit 70 maintains the lighting of the under-mirror lighting unit L1a in the second lighting state (step S214). If the water discharge flow rate becomes 0 L / min (step S215: YES), that is, if water discharge has ended (step S216), the control unit 70 ends the water discharge / illumination control (step S217).

[0124] In this way, when the flow rate of water discharged from the water discharger 41 is less than a predetermined amount, the control unit 70 turns on the first lighting means L1 in the first lighting state. On the other hand, when the flow rate of water discharged from the water discharger 41 is equal to or greater than a predetermined amount, the control unit 70 turns on the first lighting means L1 in the second lighting state. Note that this predetermined amount may be determined appropriately and is not particularly limited.

[0125] When the amount of water discharged from the water discharger 41 is equal to or greater than a predetermined amount, that is, when the user needs water to be discharged at a flow rate equal to or greater than a predetermined amount, the first lighting means L1 is turned on with a high color temperature and / or illuminance, thereby improving visibility and usability. For example, when a flow rate equal to or greater than a predetermined amount is required, such as when cleaning stains on clothes, the control unit changes the color temperature of the first lighting means from incandescent to neutral white or increases the illuminance. This, for example, brightens the surroundings, improving visibility of the degree of dirt removal.

[0126] FIG. 7 is a flowchart illustrating the operation of the washing unit according to the embodiment. Fig. 7 shows the water discharge / illumination control. The water discharge / illumination control corresponds to, for example, steps S105 to S107 described with reference to Fig. 5. In the example of Fig. 7, the first illumination means L1 is an under-mirror illumination unit L1a.

[0127] The control unit 70 starts water discharge and lighting control (step S301). At this time, the control unit 70 turns on the under-mirror lighting unit L1a in the first lighting state.

[0128] Thereafter, the control unit 70 goes into a standby state (step S302). If an object (hand) is not detected in the detection area A (step S303: NO) and an object is not detected in the detection area B (step S304: NO), the standby state continues (step S302).

[0129] If an object is detected in detection area B (step S304: YES), the control unit 70 causes the water faucet device 14 to discharge water in continuous water discharge mode (mode B). That is, the control unit 70 opens the solenoid valve 80, the solenoid valve 81, etc., to discharge water from the water discharge unit 41 (discharge unit 42) (step S305).

[0130] At this time, the control unit 70 changes the under-mirror lighting unit L1a from the first lighting state to the second lighting state (step S306). That is, the control unit 70 increases the illuminance and / or color temperature of the under-mirror lighting unit L1a.

[0131] Thereafter, if no object is detected in the detection area B (step S307: NO), the control unit 70 maintains the state in which the solenoid valves 80 and 81 are open and the water outlet 41 is outlet (step S305), and maintains the lighting of the under-mirror lighting unit L1a in the second lighting state (step S306).

[0132] If an object is detected again in detection area B (step S307: YES), the control unit 70 closes solenoid valve 80, solenoid valve 81, etc. to end water discharge in the continuous water discharge mode (step S308), and the water discharge / lighting control ends (step S309).

[0133] In the standby state, if an object is detected in the detection area A (step S303: YES), the control unit 70 causes the water faucet device 14 to discharge water in the automatic water discharge mode (mode A). That is, the control unit 70 opens the solenoid valve 80, the solenoid valve 81, etc., and causes water to be discharged from the water discharge unit 41 (discharge unit 42) (step S310).

[0134] At this time, the control unit 70 maintains the lighting of the under-mirror lighting unit L1a in the first lighting state (step S311). While an object is detected in the detection area A (step S312: YES), the control unit 70 maintains the state in which the solenoid valves 80 and 81 are open and the water discharger 41 discharges water (step S310), and maintains the lighting of the under-mirror lighting unit L1a in the first lighting state (step S311).

[0135] When an object in the detection area A is no longer detected (step S312: NO), the control unit 70 closes the solenoid valve 80, the solenoid valve 81, etc. to end water discharge in the automatic water discharge mode (step S313), and the water discharge / lighting control ends (step S314).

[0136] In this way, the control unit 70 turns on the first lighting means L1 in the first lighting state when the automatic water discharge mode is selected, that is, when the water discharge unit 41 discharges water because the object detection sensor 61 detects an object in the detection area A. On the other hand, the control unit 70 turns on the first lighting means L1 in the second lighting state when, for example, the continuous water discharge mode is selected, that is, when the water discharge unit 41 discharges water because an operation input is performed on the operation unit 63.

[0137] When the continuous water discharge mode is selected, that is, when the user needs continuous water discharge, for example, the first lighting means L1 is turned on with a high color temperature and / or illuminance, thereby improving visibility and usability. For example, when water discharge is required for a certain period of time, such as when cleaning stains on clothes, the control unit 70 changes the color temperature of the first lighting means L1 from incandescent white to daylight white or increases the illuminance. This, for example, brightens the surroundings and improves visibility of the degree of dirt removal.

[0138] 8(a) and 8(b) are schematic diagrams illustrating some modified examples of the washing unit according to the embodiment. FIG. 8(a) is a plan view of a portion of the washbasin unit seen from above, and FIG. 8(b) is a side view of a portion of the washbasin unit seen from the side.

[0139] In this example, the detection sensor 62 also serves as an operation unit 63 for causing the water faucet device 14 to execute the continuous water discharge mode. That is, the detection sensor 62 also serves as a sensor for detecting the user's hand held out in the detection area B. In this example, the detection area B is near the left end of the bowl portion 22. However, the detection area B is not limited to this, and it is sufficient that the detection area B is set so as not to overlap with the detection area A. In this way, in the embodiment, the sensors and switches may be appropriately shared to the extent possible.

[0140] In addition, sensors and switches may be appropriately individualized to the extent possible. For example, a switch or sensor (e.g., a sensor for detecting detection area A) for causing the water faucet device 14 to dispense water in the automatic water dispensing mode may be provided in addition to the acquisition unit 60 (e.g., a sensor for detecting detection area C) that acquires the entry detection information.
