(composition)
In this embodiment, the mirror display of the present invention is applied to a vanity unit. However, the application of the mirror display of the present invention is not limited to the mirror unit of the vanity unit. The mirror display may be used in the mirror unit in the bathroom of a house, a commercial facility, a public facility, etc., a full-length mirror in the entrance, an information providing area installed at the entrance of a building, etc.
The bathroom vanity unit of this embodiment has a mirror surface portion as shown in Figs.
The vanity unit of this embodiment is equipped with a mirror, an LCD monitor 2 as a display device, a human body detection sensor 8, and a body temperature measuring device 9 on the mirror surface as a mirror display. The mirror display further includes a control unit 3 for the display device, and a communication device 4. Reference numerals 2A and 4A denote power cables for the LCD monitor 2 and the communication device 4, respectively.

The mirror 1 is the mirror body of the mirror display, and in this embodiment is made of a half mirror that can transmit light from the back surface.
The LCD monitor 2 constitutes a display device that displays images by emitting light. The LCD monitor 2 is disposed with its display surface facing the rear surface of the mirror 1. From the viewpoint of making the display through the mirror 1 clearer, it is better to have the display surface of the LCD monitor 2 in contact with the rear surface of the mirror 1, but in consideration of heat dissipation from the LCD monitor 2, it is preferable to have a small gap between the rear surface of the mirror 1 and the LCD monitor 2.
It is preferable that the display surface of the LCD monitor 2 overlaps with 70% or more of the mirror 1.
A frame 5 is provided around the periphery of the LCD monitor 2, and the mirror 1 and the LCD monitor 2 are attached to a rising portion 16A of a frame 16 of the bathroom vanity unit by the frame 5. The rising portion 16A is disposed in contact with a wall 35 of a building, for example.

The body 16 has the above-mentioned rising portion 16A and a horizontal portion 16B that is continuous with the lower end of the rising portion 16A. The horizontal portion 16A of the body 16 is supported by the base portion 11.
In addition, a beam member 7 is disposed below the mirror 1. The beam member 7 extends in the same direction as the left-right direction of the mirror 1.
The human body detection sensor 8 is a sensor that detects the presence or absence of a person in front of the mirror 1 (for example, within a range of 2 m). In this embodiment, the human body detection sensor 8 is disposed on the front surface of the beam member 7 with its detection portion facing forward. A signal detected by the human body detection sensor 8 is supplied to the control unit 3. The human body detection sensor 8 is, for example, an infrared sensor.

The body temperature measuring device 9 is a sensor that measures body temperature in a non-contact manner, and is disposed on the underside of the beam member 7 with its detection portion facing downward, specifically toward the horizontal portion 16A. In this embodiment, a body temperature measuring device 13 is also provided on the front side.
In addition, an ultraviolet sterilization lamp 10 is disposed below the beam member 7, and ultraviolet rays as sterilizing light can be irradiated downward. The symbol ARA3 is an example of an irradiation range of ultraviolet rays, which overlaps with the measurement range ARA2 of the human body detection sensor 8.
Reference numeral 12 denotes an illuminance sensor which detects the brightness around the mirror surface.
Reference numeral 14 denotes a power switch for the LCD monitor 2 .
Reference numeral 6 denotes a planar speaker.

Reference numeral 31 denotes a body composition scale placed on the floor 30 in front of the bathroom vanity.
The communication device 4 is a device that acquires information from an external device 20 by wireless communication. Reference numeral 21 denotes the Internet.
The control unit 3 controls the LCD monitor 2. When the control unit 3 determines that a person has been detected based on a signal from the human body detection sensor 8, it sets the monitor unit of the LCD monitor 2 to an active state (light-emitting state), and when the control unit 3 determines that a person has been detected based on a signal from the human body detection sensor 8, it sets the monitor unit (display unit) of the LCD monitor 2 to a non-active state (e.g., a standby state).

Furthermore, when the control unit 3 acquires display information from the body temperature measuring device 9, the external device 20, or the like while the display unit of the LCD monitor 2 is in an operating state, it executes a process to display the information on the display unit of the LCD monitor 2. For example, the control unit 3 displays the body temperature via the LCD monitor 2 based on a signal from the body temperature measuring device 9. In Fig. 2, ARA1 is a position that overlaps with the display unit of the LCD monitor 2 and indicates the displayable area. Information that is always displayed or is frequently displayed is preferably displayed in the upper and lower ranges of the mirror 1, such as ARA1-1 and ARA1-2, avoiding the center of the mirror.
The external device 20 is, for example, a body composition meter 31. That is, the control unit 3 performs a process of displaying body composition information on the LCD monitor 2 based on a signal from the body composition meter 31 via the communication device 4.

(Action etc.)
In this embodiment, the mirror surface portion can achieve both the function of the mirror 1 that reflects a person and the function of the LCD monitor 2 that displays information.
Also, the LCD monitor 2 is not always turned on, but is turned on only when a person approaches the mirror 1. This reduces the power consumption of the LCD monitor 2.
In addition, since the LCD monitor 2 overlaps almost the entire surface of the mirror 1, the LCD monitor 2 lights up when approaching the mirror 1, and the light from the LCD monitor 2 acts as indirect lighting for almost the entire surface of the mirror 1, making it easier to see around the mirror 1. At this time, the brightness of the LCD monitor 2 may be adjusted according to the brightness around the mirror 1.

Also, by simply placing a hand under the mirror 1, the body temperature is measured and displayed through the mirror 1. That is, although there is a high need for body temperature measurement, since the measurement is performed under the mirror 1, body temperature measurement can be performed regardless of height differences.
Here, by confining the display through the mirror 1 mainly to the upper and lower areas of the mirror 1 (ARA1-1 and ARA1-2), it is possible to minimize the influence on the person's reflection in the mirror 1.

A light-transmitting wood-grain decorative material may be attached to the front of the beam member 7. The body temperature numerical value can be displayed through the wood-grain sheet. In this case, a display ARA4 is also provided on the front of the beam member 7. That is, the body temperature and the like may be displayed separately on the front of the beam member 7 in addition to the display through the mirror 1. The display on the front of the beam member 7 can be achieved by, for example, arranging an LCD monitor. The symbol ARA4 is an example of a display section provided on the front of the beam member 7. An operator that commands the display on the LCD monitor 2 may be provided on the front of the beam member 7.

The information displayed through the mirror 1 may be, for example, a clock, a weather forecast, measured weight, body temperature, sleep information, and sleep information provided under the mattress.
The weight, body temperature, and sleep information may be displayed in a graph, etc. Also, the weight and sleep may be displayed in a format that allows the user to see at a glance whether the weight or sleep was better or worse than yesterday or the average.
Also, a video sharing site may be displayed so that a video can be displayed through the mirror 1.
The information measured by the body temperature measuring device 9 may be collected on an external server via communication means, and may be configured to be viewable and operable on a smartphone, and viewable and displayed on the mirror 1.
It is preferable not to install a camera due to privacy concerns.

In this embodiment, the following configuration can also be adopted.
(1) A mirror display having a mirror surface that reflects the front, the mirror surface comprising: a half mirror that reflects the front; a display device that is arranged on the rear surface of the half mirror and faces the rear surface of the half mirror to display information by emitting light; a human body detection sensor that detects the presence or absence of a person in front of the half mirror; and a body temperature measuring device that measures body temperature without contact, wherein, when viewed from the front, the display surface of the display device overlaps with the half mirror by 70% or more; and a control unit that controls the display device, wherein the control unit controls the screen display of the display device to be displayed only when it is determined that the human body detection sensor has detected a person, and controls the body temperature information detected by the body temperature measuring device to be displayed on the display surface of the display device.

According to this configuration, the mirror surface can have both the function of reflecting people and the function of projecting and presenting information through the mirror. Even if the mirror has the function of displaying information through the mirror as described above, the power consumption of the display device can be reduced by projecting information only when a person stands in front of the mirror. In addition, when a person stands in front of the mirror, the display device starts displaying, so that when a person approaches the mirror display, the light from the display device becomes indirect lighting for the mirror, making it easier to see around the mirror surface. Since the display surface of the display device overlaps with the half mirror by 70% or more when viewed from the front, it is possible to display information on almost the entire surface of the mirror, and indirect lighting is provided for the entire mirror surface. In addition, body temperature can be measured by simply placing a hand near the mirror. The measured body temperature can be displayed, for example, by the display device.

(2) The body temperature measuring device is disposed below the half mirror with its detection direction facing downward so that it can measure the temperature of a part of the human body placed below the body temperature measuring device.
According to this configuration, although there is a high need for measuring body temperature, since the measurement is performed under the mirror, body temperature can be measured regardless of height differences.
(3) The display device includes a communication device that acquires information from an external source, and the control unit controls the display of the information received by the communication device on the display surface of the display device.
This configuration makes it possible to provide a variety of information.
(4) A germicidal lamp that irradiates light downward together with the body temperature measuring device is provided below the half mirror, and the irradiation range of the germicidal lamp overlaps with the measurement range of the body temperature measuring device.
