The present invention relates to radiant heating devices.
Various solutions exist for heating spaces. Heat can be provided to a complete building (central heat), such as a residence, by a furnace that heats air, e.g. by combustion of a gas, which heated air is blown through vents into the buildings room (forced air). Alternatively, a boiler can heat water, oil or other fluids that circulate through pipes or “radiators” to heat rooms with radiant heat.
Some situations call for “space heaters,” namely heaters that are designed for providing heat to a single space within a building. Space heaters can also use forced air, i.e. heating air and blowing it into the room, or radiant heat, i.e. heating a fluid in a radiator or using heating elements that radiate heat into the room. Naturally, safety is a critical concern for any space heater, especially since most space heaters sit on the floor, where they might be touched by a child or a pet, or even worse, where they might be knocked over and come into contact with something flammable.
Some space heaters utilize reflective material and radiant heat to create a heating mirror. An advantage to heating mirrors is that they do not take up very much space and are functional as both a heater and mirror, but they carry an added safety concern. When there is no visual distinction between a mirror and a heating mirror, it is likelier that a person comes into contact with the hot surface of the heating mirror, since they would not expect the surface of a mirror to be hot.
A separate enhancement to the simple mirror is connectivity to the Internet or various user devices. Such a mirror is sometimes known as a “smart mirror”. With a connection to the Internet, smart mirrors can curate and display information helpful to users, from the current time to weather forecasts and news headlines.
In a first aspect, the invention is a heating and display mirror. The mirror is composed of two different “zones”, one for heating and one for display. The heating zone is heated by radiant heat, and the display zone features a display device that produces lighted images visible on the mirror's surface. The heating and display zones are operated by user controls, which give instructions to the heating zone to turn on and off, and to the display zone regarding what images to display on the lighted display device.
In a second aspect, the invention includes a pentiometer in order to adjust the voltage supplied to the heating zone, and in turn adjust the amount of heat produced. In a third aspect, the invention includes a temperature sensor and a thermostat function, which adjusts the heat in accordance with a desired temperature as set by a user. In a preferred embodiment, a temperature sensor is adapted to measure the heat of the mirror's surface, and send signals to the controller that prevent the surface temperature to go beyond a maximum, as set by factory standards or the user.
In another aspect, the mirror includes a visual indicator that, in conjunction with the surface temperature sensor, informs the user when the mirror is in certain states, including heating, warm, and off (neither heating nor warm). A preferred aspect includes this visual indicator as part of the display zone.
In a preferred aspect, the invention includes sensors, both attached and remote, that collect data and send signals to the wireless communication device, which the controller interprets and sends instruction to the heating zone or display zone as appropriate. Preferably, these include light, motion, temperature, and humidity sensors. Also, a preferred embodiment includes a speaker, enabling functions such as playing music, and alerting the user of various information aurally. A microphone is also included, which the user can use to provide voice instructions. The preferred embodiment also has a light to illuminate the user, and an embedded camera to enable the user to capture images hands-free.
In another aspect, the display zone also includes a touch-sensitive sensor, for controlling the display zone as well as the heating zone. In an additional aspect, the wireless communication device is adapted to send and receive information to other smart devices. Examples include a user's smart phone, as well as other smart devices in the house such as windows and window coverings, a smart thermostat, and an internet-enabled alarm clock.

Referring to
The heating and display mirror 100 is demarcated into two separate “zones”, the heating zone 104 and display zone 106. Visible in an exploded view of the mirror 100, a second layer of the mirror is itself divided into two distinct zones, heating zone 112 and display zone 110. The heating zone 112 includes a radiant heating device, and the display zone 110 includes a display device.
The preferred shape and dimensions of the mirror and included heating and display zones depends on various factors. Naturally, aesthetics are important to consider. While rectangular shapes are generally preferred, in some situations, a round, oval or other shape may be desirable. The dimensions should be selected so as to be aesthetically pleasing as well as functional. The display zone should be large enough to display detailed images, but not so large that it inhibits the functionality of the heating zone or the general uses for a mirror. In heating and display mirror 100 the display zone is located above the heating zone and proportionately smaller than the heating zone. The relative location and size of the display and heating zones will vary depending on the shape of the mirror, its intended usage within the residence, or other factors. Although in the tall rectangular shape, the placement of the display zone above the heating zone is convenient for a user to see while standing in front of it, other sized mirrors in different residential functions may be optimized by placing the display zone in a completely different spot. Additionally, although not depicted in this embodiment, the display zone may be surrounded by the heating zone, i.e. not located along the edge of the mirror. Shipping considerations should also be taken into account.
A feature of the display zone 110 is a display device 118. Display device 118 is adapted to show any series of images, which are visible in the display zone 106. The display zone 106 is comprised of a transparent layer through which the images from the display device 118 can be seen. The display device 118 is designed to illuminate the images it produces, so that they are easily visible in the display zone 104. In a preferred embodiment, the display device is adapted to adjust the illumination of its screen, so as to optimize visibility and energy efficiency. The screen illumination may be adjusted to adapt to its surroundings with a controller and a light sensor. The light sensor may send signals to the controller through a hardwired data connection, or via a wireless communication device.
The heating layer 112 provides radiant heat via a current source and resistive wire 120. Radiant heat is produced when current travels through the resistive wire 120. The resistive wire may be arranged as depicted, or in other forms, including but not limited to a coil, connected vertical rows, or connected horizontal rows. However, other embodiments of the heating layer may produce radiant heat through alternative methods.
As depicted in

As shown in
The properties and dimensions of the elongated conductors and the sheet of resistive material are selected so as to produce the desired range of heat produced by the heater and the surface temperatures desired for the heater. Preferably, the resistive sheet is between 5 and 35 centimeters across, i.e. between the conductors, more preferably between 30 and 35 centimeters, and most preferably 34 centimeters. At this most preferred width, the Nanoxene® material produces about 150 watts per meter. Thus, with the most preferred height of the mirror being about 1.115 meters, the wattage of the heater is about 170 watts.
The preferred embodiment also includes a backing layer 210, which should have thermal insulating properties. Preferably, the backing layer comprises a backing sheet and a sheet of insulating material 212. This can be an important feature in preventing the heater from heating up the wall it is attached to and to direct heat forward. Most preferably, the sheet of insulating material 212 includes a metallic foil film that helps reflect radiant heat forward.
Preferably, the heater also includes a frame 218 for holding the heating layer 202, the sheet of insulating material and the backing sheet 107 together. Most preferably, this frame is made from an extruded aluminum alloy.
The backing layer 210 should also have a wall mounting element, such as a hook or bracket 214 for mounting the heater on a wall. Alternatively, the mounting element can employ an adhesive, such as a peel-and-stick pressure-sensitive adhesive pad or pads.
Naturally, safety is the most important factor in designing any heater. The heater of the present invention is designed so that the surfaces never exceed safe temperatures, i.e. 70° C. Preferably, the surfaces of the heater never exceed 68° C., more preferably 65° C. and most preferably 60° C. These maximum temperatures are preferably set at the factory. In the depicted embodiment 100 the maximum temperature on the front of the mirror should be about 65° C.
In the simplest embodiment, the heater is merely switched on by the user when heat is needed and switched off by the user when it is not. Alternatively, the heater includes a settable thermostat, whereby the user sets the desired temperature to which the heater heats its environment. Alternatively, the thermostat can be used to enter a desired maximum temperature and/or a desired minimum temperature. Feedback for the thermostat may come from on onboard thermal sensor or transducer. Alternatively, the feedback may come from a remote sensor or device.
Again, in the simplest embodiment, the heater is designed to either be on or off, whether put in that state by the user or a controller. As seen in
In the preferred embodiment shown in
The transparent layer 102 is a mirror. Preferably, this reflective layer is applied as a coating on the back of the transparent layer. This can be referred to as a silvered backing or coating. The most preferred material for silvering is aluminum, although silver, gold, tin and other shiny metals and alloys may be used. Alternatively, a sheet of reflective material may be used in place of a transparent layer to fulfill the function of a mirror.

To differentiate the different indicators, in one embodiment each indicator is a different color. For example, the indicator that indicates the surface of the mirror is hot is a red color, so that a user can quickly ascertain that, when the red light is on, the surface of the mirror is too hot to touch. In this embodiment, the indicator for warming could be yellow, and the indicator for when the desired temperature is reached is green.
With indicator 308 communicating that the mirror is heating, a user can know a number of useful things. For example, if the room they are in with the mirror feels cold, they can tell by the light indicator if the mirror is currently warming the room, or if settings need to be changed or controls set to turn on the heating device. The indicator 310 that indicates a desired temperature has been met further gives the user information to adjust the settings or controls. If the user is too warm, and indicator 310 is lit, the user may choose to turn the heating device off, or the user may choose to lower the desired temperature and allow the controls and pentiometer to adjust the heat accordingly. Indicator 306 takes into account the fact that the surface of the mirror remains warm for a time even after the heating device is turned off. Knowing that the surface of the mirror is not hot allows the user to touch the mirror without worry. There are certain times that the user would want to know the mirror surface is not hot, such as when they would like to clean or move the mirror. Additionally, the user may take extra precaution when the surface of the mirror is hot, such as ensuring small children are not left unsupervised near the mirror.
Display 304 is one embodiment of these three indicators, but this same information can be communicated to the user in different formats, or the indicators may be used to communicate different information. Alternatively, an embodiment of the indicator display could have a greater or smaller number of indicators than display 304. The preferred embodiment includes indicators for the three conditions described, but the indicators are incorporated into the display zone. In the preferred embodiment, the indicator that the mirror is hot, and the mirror is heating, are displayed digitally within the display zone, and are not independently illuminated.

In the most preferred embodiment, the display zone does not only display information, but also receives signals from the user via a touch-sensitive screen, as depicted in
In the preferred embodiment, the display device is also able to receive instructions via a connected microphone. Additionally, in the most preferred embodiment, the display and heating mirror is equipped with a speaker 414. With voice commands, the user can not only control the heating device but also functioning of the display device. The speaker 414 on the display device 402 can be used a number of ways. The user may wish to listen to music while they are getting ready for the day, or play a daily newst podcast. Additionally, the user is able to stream audiovisual contect on the display device.
As shown, the mirror 402 includes the display zone 404. The mirror 402 in the bathroom preferably includes lights 406 for illuminating the bathroom, and particularly for illuminating the user in front of the mirror. Preferably, the lights 406 are controlled through the touch-sensitive display zone 404. Most preferably, the lights 406 are dimmable.
The mirror 402 also preferably includes at least one sensor 408. Sensor 408 is a remote sensor, although the mirror may have sensors within the mirror's construction. Sensor 408 detects motion. This sensor can be used to detect when a person walks into the bathroom. In response, the heating mirror may be programmed to automatically turn itself on and start heating the bathroom. The mirror may also be programmed so that the lights 406 turn on in response to someone entering the room.
The sensor or sensors 410 may also be used to detect the forming of or potential for forming of moisture droplets on the mirror (fogging). Sensor 410 on the mirror's surface detects when water droplets are on the mirror; an alternative sensor could measure the general moisture level in the room. In response, the heater may be activated to prevent or ameliorate fogging. In the preferred embodiment, when the heater is activated by a humidity sensor, a “fog reduction” heat setting is switched on, which emits a lower amount of heat than what is generally used to heat up a room.
The sensor or sensors (410) may also be used to detect temperature. Preferably, the sensor detects the temperature of the air in front of the mirror. Most preferably, this is accomplished by an infrared sensor. As such, this temperature data can be used by the mirror to determine if the heater should be on or off, or the level of heat produced by the heater, so as to maintain the temperature of the bathroom at the level set by the user. Alternatively, the sensor detects the temperature of the mirror and extrapolates to the temperature of the air in the bathroom.
The mirror 402 also preferably includes a switch 412 for interrupting current to the mirror, to thereby cut power to the mirror. Alternatively, the heater and/or display device can be turned off via touch-sensitive controls in the display zone.
In some embodiments, the heater is activated by a motion sensor, to detect someone entering the room. In other embodiments, the heater is turned on and off with the lights in that room. For, as someone turns on the lights as he enters the bathroom, he is also turning on the heating mirror. As he turns off the lights and leaves, he is also turning off the heating mirror. In yet other embodiments, the heater is designed to turn off after a certain period of time from being turned on, or after a certain period of time after the motion sensors detect motion.
Preferably, the mirrors of the present invention can be controlled wirelessly. More preferably, the mirrors of the present invention can be controlled as elements in an “Internet of Things” fashion as part of a “smart home” and programmed with devices, such as those using IFTTT programming. Referring to
The heating and display mirror may connect to other smart home, or IoT, devices. In one embodiment, the heating and display mirror may share information and controls with an automated window to optimize the user experience. For example, the mirror 402 could send instructions to automated window 506 to close when the heating zone is activated. Such controls can be overridden by a user, but they are generally designed to increase heating efficiency.
Preferably, the user communicates with the controller by means of a smart phone running an app. Through that app, the user also receives feedback information about the state of the mirror. Most preferably, the app is adapted to control and receive feedback from multiple IoT devices.
In alternative embodiments, the mirror is supplied with a dedicated remote control device. Preferably, that remote control device can be mounted on the wall of the room. When a dedicated remote control device is used, it is preferable to incorporate a temperature sensor, so that it can give feedback to the heater as to the temperature within the room.
