(Embodiment)
The configuration of the mirror device 1 according to the embodiment will be described with reference to FIGS. FIG. 1 is a front view of a mirror device 1 according to an embodiment. FIG. 2 is an enlarged front view of the main part of the mirror device 1. 3 is a cross-sectional view taken along line III-III in FIG. FIG. 4 is a plan view of a capacitance sensor 31 used in the sensor unit 30 of the mirror device 1. FIG. 5 is a cross-sectional view of the capacitance sensor 31 taken along the line VV in FIG.

  As shown in FIG. 1, the mirror device 1 is, for example, a vanity, and includes a mirror 10 for reflecting a user standing in front of the vanity, a vanity 40, and a cabinet 50. The mirror device 1 in the present embodiment is a lighted vanity, and further includes a lighting fixture 20 and a sensor unit 30 for operating the lighting fixture 20.

  As shown in FIGS. 2 and 3, the mirror 10 includes a reflective metal layer 11 and a transparent layer 12 provided on the front side of the reflective metal layer 11. That is, the reflective metal layer 11 is provided on the back side (back side) of the transparent layer 12.

  The surface of the reflective metal layer 11 is a mirror surface and can reflect the user's appearance. The reflective metal layer 11 is a metal film made of a metal such as silver or aluminum. The transparent layer 12 is a glass layer, for example, and has a function of protecting the reflective metal layer 11 and transmitting light completely. The reflective metal layer 11 can be formed, for example, by using a glass substrate as the transparent layer 12 and depositing silver or aluminum on the surface of the glass substrate.

  The reflective metal layer 11 has a first opening 11a and a second opening 11b. The first opening 11 a is formed at a position facing the sensor unit 30. In addition, the second opening 11 b is formed at a position facing the lighting fixture 20. In the present embodiment, since two lighting fixtures 20 are provided, two second openings 11b are also formed. In addition, the shape of the 1st opening part 11a and the 2nd opening part 11b when the mirror 10 is viewed in front can be made into the shape according to the external shape of the sensor unit 30 and the lighting fixture 20, for example, is a rectangular shape.

  The lighting fixture 20 is an example of an electrical device and is disposed around the mirror 10. In the present embodiment, the lighting fixture 20 is arranged on the back side of the mirror 10. Specifically, the lighting fixture 20 is attached to the back surface (back surface) of the mirror 10. For this reason, in order to take out the illumination light of the lighting fixture 20 to the front side, the reflective metal layer 11 is not formed in the front part of the lighting fixture 20. Specifically, a second opening portion 11 b is formed in the reflective metal layer 11 at the front portion of the lighting fixture 20. Thereby, the lighting fixture 20 can irradiate light from the 2nd opening part 11b. That is, the illumination light emitted from the luminaire 20 passes through the transparent layer 12 through the second opening 11b and is irradiated forward from the mirror 10.

  As illustrated in FIGS. 2 and 3, the lighting fixture 20 includes a light emitting module 21 and a fixture housing 22 that houses the light emitting module 21.

  The light emitting module 21 is, for example, an LED module, and includes a plurality of light emitting elements 21a that emit white light and a substrate 21b. The light emitting element 21a is, for example, an LED element configured by LEDs. The board 21b is a printed circuit board having metal wiring formed in a predetermined pattern.

  The instrument housing 22 is made of, for example, metal, but may be made of resin. An opening is provided on the mirror housing 10 side of the instrument housing 22, and light emitted from the light emitting module 21 is radiated to the outside of the instrument housing 22 through the opening. The opening of the instrument housing 22 may be covered with a translucent plate. In addition, although not shown in figure, the instrument housing | casing 22 may accommodate the power supply circuit unit which produces | generates the electric power for making the light emitting module 21 (light emitting element 21a) light-emit. The electric power generated by the power supply circuit unit is supplied to the light emitting module 21. Thereby, the light emitting module 21 emits light.

  Moreover, the lighting fixture 20 may have a light control function for controlling the brightness of illumination light and a color control function for controlling the emission color of illumination light. By dimming or toning the lighting fixture 20, it is possible to adjust the brightness of the surroundings or improve the color of the user's skin.

  As shown in FIGS. 2 and 3, the sensor unit 30 detects the user's operation when the user operates the lighting fixture 20. The sensor unit 30 functions as an operation switch. For example, the sensor unit 30 can control on / off of the lighting fixture 20 and can control light adjustment and color adjustment of the lighting fixture 20.

  The sensor unit 30 is disposed on the back side of the mirror 10. In the present embodiment, the sensor unit 30 is attached to the back surface of the mirror 10. For this reason, the reflective metal layer 11 is not formed in the front part of the sensor unit 30. Specifically, a first opening 11 a is formed in the front portion of the sensor unit 30 in the reflective metal layer 11.

  The sensor unit 30 includes a capacitance sensor 31 and a sensor housing 32 that houses the capacitance sensor 31. The sensor housing 32 is made of metal, for example, but may be made of resin. The capacitance sensor 31 functions as an operation switch for the user to operate the lighting fixture 20. For example, when the user performs on / off control, dimming control, or long color control on the lighting fixture 20, the capacitance sensor 31 detects the user's operation and operates the lighting fixture 20. Output a signal.

  As shown in FIGS. 4 and 5, the capacitance sensor 31 includes a sensor electrode 31a and a substrate 31b on which the sensor electrode 31a is formed. The capacitance sensor 31 is a capacitance-type proximity sensor (non-contact sensor), and detects the approach of the user's hand by detecting a change in capacitance by the sensor electrode 31a.

  The sensor electrode 31a is formed on one surface (front surface) of the substrate 31b. The sensor electrode 31 a is disposed at a position facing the first opening 11 a formed in the reflective metal layer 11. That is, since the metal has an effect of shielding the electric field, if the reflective metal layer 11 exists on the front side of the sensor electrode 31a, the sensor electrode 31a does not function as a sensor, so the sensor electrode 31a is covered with the reflective metal layer 11. Not. The user can visually recognize the sensor electrode 31a through the first opening portion 11a, and operates the sensor electrode 31a as a switch when performing on / off control of the lighting fixture 20 or the like.

  The sensor electrode 31a is made of, for example, a metal material such as copper or silver, and is formed in a predetermined pattern on one surface of the substrate 31b. The sensor electrodes 31a are, for example, solid electrodes having a circular shape in plan view, and in the present embodiment, two sensor electrodes 31a are formed on the front side (mirror 10 side) surface of the substrate 31b. The two sensor electrodes 31a are formed at a predetermined interval. The substrate 31 b is a wiring substrate on which metal wiring is formed, and is housed in the sensor housing 32.

  The capacitance sensor 31 further includes a ground electrode 31c disposed on the back side of the sensor electrode 31a. The ground electrode 31c is formed on the substrate 31b, and is formed on the back side of the surface of the substrate 31b where the sensor electrode 31a is formed. The ground electrode 31c is set to a ground potential (ground potential).

  In the present embodiment, a multilayer substrate having a laminated structure of an insulating layer and a wiring layer is used as the substrate 31b, and the ground electrode 31c is a ground layer, for example, and is formed as an inner wiring layer of the multilayer substrate. Yes. That is, the ground electrode 31c is arranged between one surface, which is the surface on which the sensor electrode 31a of the substrate 31b, which is a multilayer substrate, is formed, and the other surface, which is the surface opposite to the one surface. ing. As the ground electrode 31c, a solid electrode made of a solid film or a mesh-like mesh electrode can be used. Note that the shape of the ground electrode 31c is not limited to these, and a ground electrode having a pattern formed in a predetermined shape can be used.

  2 and 3, a part of the ground electrode 31c overlaps the reflective metal layer 11 when the mirror 10 is viewed from the front. In FIG. 2, hatched hatching is applied to the portion where the ground electrode 31c and the reflective metal layer 11 overlap. As shown in FIG. 2, in the present embodiment, the ground electrode 31 c overlaps with the reflective metal layer 11 in the entire circumference of the opening of the first opening 11 a. Specifically, the ground electrode 31c is formed so as to protrude from the entire periphery of the first opening 11a so as to cover the entire region of the first opening 11a.

  A plurality of circuit components 31d and connectors for driving the sensor electrode 31a are mounted on the other surface of the substrate 31b. The plurality of circuit components 31d constitute a sensor circuit and detect a change in capacitance due to the detection target approaching the sensor electrode 31a. Since the ground electrode 31c is formed on the front side of the circuit component 31d, noise generated from the circuit component 31d can be shielded by the ground electrode 31c. That is, the ground electrode 31c functions as a shield layer. Further, a bias electrode (bias layer) to which a specific potential is applied may be separately formed on the substrate 31b.

  Here, a method of detecting the finger of the user's hand by the capacitance sensor 31 will be described with reference to FIG. FIG. 6 is a diagram for explaining a method of detecting the finger of the user's hand by the electrostatic capacity sensor 31.

  As shown in FIG. 4, in the present embodiment, the capacitance sensor 31 has two sensor electrodes 31a, and the two sensor electrodes 31a can detect that the user's hand is approaching. .

  Specifically, as shown in FIG. 6, when the user performs on / off control, dimming control, or the like of the lighting device 20, the user moves the fingertip from one electrode of the two sensor electrodes 31 a to the other electrode. May be moved in the horizontal direction.

  At this time, for each of the two sensor electrodes 31a, when the user's fingertip approaches the sensor electrode 31a, the capacitance (capacitance value) between the sensor electrode 31a and the finger increases, and the user's fingertip moves away. The electrostatic capacitance (capacitance value) between the sensor electrode 31a and the finger decreases.

  Accordingly, the capacitance sensor 31 has a capacitance (capacitance value) that changes when the user's fingertip moves from one electrode of the two sensor electrodes 31a to the other electrode. By detecting with, it is possible to electrically detect the approach of the user's finger. Note that the change in capacitance value is, for example, several pF.

  The capacitance sensor 31 generates a detection signal when detecting that the user's fingertip is approaching, and outputs the generated detection signal to the lighting fixture 20. Thereby, the user can perform on / off control of the lighting fixture 20 or the like.

  Further, in the present embodiment, it is detected that the user's hand is approaching using the two sensor electrodes 31a, but as shown in FIG. 7, it is detected that the user's hand is approaching using one sensor electrode 31a. It may be configured to. In this case, for example, when the user performs an operation of moving the fingertip closer to or away from the capacitance sensor 31, the capacitance sensor 31 can detect that the user's fingertip has approached.

  Specifically, when the user performs on / off control or the like of the lighting fixture 20, as shown in FIG. 7, the user pulls the fingertip close to the capacitance sensor 31 and quickly pulls the capacitance sensor 31. It is possible to detect that the user's fingertip is approaching. In this case, the capacitance sensor 31 changes the capacitance (capacitance value) generated between the sensor electrode 31a and the user's fingertip when the user's fingertip approaches or moves away from the one sensor electrode 31a. It detects and detects that a user's fingertip approached and generates a detection signal. Thereby, on-off control of the lighting fixture 20 etc. can be performed.

  In the case of the detection method shown in FIG. 7, for example, one of the two sensor electrodes 31a can be used as an on / off control operation switch, and the other of the two sensor electrodes 31a can be used as a dimming control operation switch.

  Moreover, the electrostatic capacitance sensor 31 can detect a detection target not only when a detection target (a user's hand etc.) approaches but also when a detection target contacts. That is, the capacitance sensor 31 can obtain sensor sensitivity by non-contact or contact, and the sensor unit 30 can operate the lighting fixture 20 by both non-contact operation and contact operation.

  In the mirror device 1 configured as described above, as shown in FIGS. 2 and 3, the reflective metal layer 11 of the mirror 10, the lighting fixture 20, and the sensor unit 30 are connected to a ground line 60 having a ground potential. . Thereby, the reflective metal layer 11, the lighting fixture 20, and the sensor unit 30 have a common ground potential. The ground line 60 is set to the ground potential by being grounded.

  Specifically, in the lighting fixture 20, the ground line 60 is connected to the substrate 21 b (circuit board) of the light emitting module 21. Thereby, the board | substrate 21b is earth | grounded. Thus, in the lighting fixture 20, it has the structure which has a grounding potential by the board | substrate 21b being earth | grounded.

  In the sensor unit 30, the ground wire 60 is connected to the ground electrode 31 c of the substrate 31 b of the capacitance sensor 31. Thus, the sensor unit 30 is configured to have a ground potential by grounding the ground electrode 31c.

  As described above, according to the mirror device 1 according to the present embodiment, the mirror 10 having the reflective metal layer 11, the lighting fixture 20 disposed around the mirror 10, and the rear side of the mirror 10, the lighting fixture 20 is provided. The reflective metal layer 11, the lighting fixture 20, and the sensor unit 30 have a common ground potential. That is, the mirror 10, the lighting fixture 20, and the sensor unit 30 are grounded in common.

  With this configuration, the members around the sensor electrode 31a of the capacitance sensor 31 (the reflective metal layer 11 of the mirror 10, the sensor circuit formed by the circuit component 31d, and the lighting fixture 20) are grounded. Electrically independent. As a result, since the influence of the parasitic capacitance of the mirror 10 on the capacitance sensor 31 is reduced, it is possible to suppress the sensor sensitivity of the capacitance sensor 31 from being lowered. That is, the sensor sensitivity of the capacitance sensor 31 is increased.

  Moreover, since the noise emitted from the lighting fixture 20 and the external noise can also be shielded, it is possible to suppress the malfunction of the capacitance sensor 31.

  As described above, according to the mirror device 1 according to the present embodiment, the mirror 10, the lighting fixture 20, and the sensor unit 30 are connected to the common ground, so that the capacitance sensor 31 of the capacitance sensor 31 is formed by the reflective metal layer 11 of the mirror 10. While suppressing that a sensitivity falls, it can reduce that the electrostatic capacitance sensor 31 malfunctions by the noise emitted from the lighting fixture 20 which is an electric equipment.

  In addition, since the mirror 10, the lighting fixture 20, and the sensor unit 30 are connected to a common ground, not only the mirror 10 but also the lighting fixture 20 and the sensor unit 30 have a ground potential. Thereby, it is possible to prevent the user from getting an electric shock even when the humidity is high and the mirror 10 is condensed or when water droplets adhere to the surface of the mirror 10. Therefore, the user can use the mirror device 1 safely.

  In the mirror device 1 according to the present embodiment, the reflective metal layer 11, the lighting fixture 20, and the sensor unit 30 are connected to a ground line 60 having a ground potential.

  Thus, by using the ground wire 60, the reflective metal layer 11, the lighting fixture 20, and the sensor unit 30 can be easily configured to have a common ground potential.

  Moreover, in this Embodiment, the sensor unit 30 can operate the lighting fixture 20 by both non-contact operation and contact operation.

  Thereby, since the freedom degree of operation of the sensor unit 30 improves, a user's convenience improves.

  In the present embodiment, the capacitance sensor 31 includes a sensor electrode 31a and a ground electrode 31c disposed on the back side of the sensor electrode 31a. The sensor electrode 31a is formed on the reflective metal layer 11. The first electrode 11c is disposed at a position facing the first opening 11a, and the ground electrode 31c is grounded. A part of the ground electrode 31 c overlaps the reflective metal layer 11 when the mirror 10 is viewed from the front.

  Thereby, since the 1st opening part 11a is covered with the ground electrode 31c, the external noise from the front surface or back surface of the mirror 10 can be shielded. As a result, noise wraparound in the peripheral area of the capacitance sensor 31 is eliminated, so that malfunction of the capacitance sensor 31 can be further suppressed and the sensor sensitivity of the capacitance sensor 31 can be further increased. In addition, the external noise from the front surface or the back surface of the mirror 10 can be completely shielded by completely covering the first opening 11a with the ground electrode 31c.

  In the present embodiment, the capacitance sensor 31 has a substrate 31b, the sensor electrode 31a is formed on one surface of the substrate 31b, and the sensor electrode 31a is driven on the other surface of the substrate 31b. A circuit component 31d is mounted. The ground electrode 31c is disposed between one surface and the other surface of the substrate 31b.

  Thereby, since the sensor electrode 31a can be electrically independent, the sensor sensitivity of the capacitance sensor 31 can be increased.

  Moreover, in this Embodiment, the lighting fixture 20 which can irradiate light from the 2nd opening part 11b formed in the reflective metal layer 11 is used as an electric equipment arrange | positioned at the back side of the mirror 10. FIG.

  Thus, the user can use the lighting fixture 20 by operating the capacitance sensor 31 (operation switch) when using the mirror 10.

  Moreover, as shown in FIG. 8, the sensor housing 32 made of metal in the sensor unit 30 may also be grounded.

  As described above, by setting the sensor casing 32 to the common ground potential, it is possible to suppress the external noise from affecting the capacitance sensor 31. In addition, electrical noise generated from the sensor circuit (circuit component) itself of the capacitance sensor 31 is sealed by the sensor housing 32. Thereby, malfunctioning of the capacitance sensor 31 can be suppressed. In addition, the sensor sensitivity of the capacitance sensor 31 is increased.

  In this case, as shown in FIG. 8, the metal fixture housing 22 in the lighting fixture 20 (electric device) may also be grounded.

  Thereby, since the electrical noise which generate | occur | produces with the lighting fixture 20 is sealed with the apparatus housing | casing 22, it can suppress that the electrostatic capacitance sensor 31 is influenced by the noise which generate | occur | produces with the lighting fixture 20. FIG. Thereby, the malfunction of the capacitance sensor 31 can be further suppressed, and the sensor sensitivity of the capacitance sensor 31 is further increased. Moreover, it can suppress that external noise influences the lighting fixture 20 by earth | grounding the fixture housing | casing 22. FIG.

(Modifications, etc.)
As described above, the mirror device according to the present invention has been described based on the embodiment, but the present invention is not limited to the above embodiment.

  For example, as shown in FIGS. 9 and 10, a capacitance sensor 31A having a ground electrode 31e formed around the sensor electrode 31a may be used. FIG. 9 is a plan view of a capacitance sensor 31A according to a modification, and FIG. 10 is a cross-sectional view of the capacitance sensor 31A taken along line XX in FIG. The capacitance sensor 31A shown in FIGS. 9 and 10 has a configuration in which a ground electrode 31e is further formed with respect to the capacitance sensor 31 shown in FIGS. The ground electrode 31e is set to a ground potential (ground potential). The ground electrode 31e is formed on the surface of the substrate 31b where the sensor electrode 31a is formed. That is, the ground electrode 31e is in the same layer as the sensor electrode 31a. Thus, the sensor sensitivity can be further improved by forming the ground electrode 31e around the sensor electrode 31a.

  Moreover, in the structure of the mirror 10 in the said embodiment shown by FIG.2 and FIG.3, the lighting fixture 20 will be exposed over the transparent layer 12. FIG. Therefore, the mirror 10 may be a magic mirror so that the luminaire 20 cannot be visually recognized by the user. Thereby, the reflective metal layer 11 in which the 2nd opening part 11b is not formed in the front of the lighting fixture 20 can be obtained. In this case, as the reflective metal layer 11, for example, a metal half-deposited can be used. Even in this case, since the capacitance sensor 31 needs to detect a change in capacitance, the first opening 11a may be formed in front of the sensor unit 30 in the reflective metal layer 11. However, since a mirror surface without electric field shielding is obtained by using a half mirror film in which non-conductive tin is deposited in front of the sensor unit 30, a mirror without an opening can be realized.

  Moreover, in the said embodiment, although the electrostatic capacitance sensor 31 was a non-contact-type non-contact sensor, it is not restricted to this, The electrostatic capacitance sensor 31 may be a contact-type contact sensor. Good. However, when a contact sensor is used, the user's consciousness that he / she does not want to touch the surface of the mirror 10 is activated, so that it is better to use a non-contact sensor as the capacitance sensor 31 from the viewpoint of user use.

  In the above embodiment, the capacitance sensor 31 is provided with two sensor electrodes 31a. However, the number of sensor electrodes 31a is not limited to this, and may be one. There may be three or more. The number of sensor electrodes 31a can be appropriately determined according to the detection method (FIGS. 6 and 7) and the control function (ON / OFF, dimming, toning, etc.) of the lighting fixture 20.

  Moreover, in the said embodiment, although the lighting fixture 20 was set as LED illumination using the LED element as the light emitting element 21a, it is not restricted to this. For example, the lighting fixture 20 may be one using an existing fluorescent lamp or the like.

  Moreover, in the said embodiment, although the lighting fixture 20 was illustrated as an electric equipment installed in the mirror apparatus 1, it does not restrict to this. For example, the electrical device installed in the mirror device 1 may be an anti-fogging heater for preventing the transparent layer 12 (glass layer) of the mirror 10 from being fogged, a display for displaying an image, or a watch. .

  Moreover, in the said embodiment, although the mirror apparatus 1 was a bathroom vanity, it is not restricted to this. The mirror device 1 may be another housing facility such as a unit bath or a mirror cabinet. The mirror device 1 can be applied to any device including a mirror and an electric device.

  In addition, the embodiment can be realized by variously conceiving various modifications conceived by those skilled in the art to the above embodiment, or by arbitrarily combining the components and functions in the above embodiment without departing from the gist of the present invention. This form is also included in the present invention.

  The present disclosure can be used as a mirror device having a mirror such as a vanity using a capacitance sensor for a user to operate an electric device.
