Abstract
One aspect of this disclosure provides a thermostat that can be magnetically attached to the wall using one or more magnets that allow the thermostat to be rotated about the wall, once mounted, or easily removed from the wall altogether to operate as a remote unit. Other devices, systems, and methods are disclosed.
Description
- This application claims the benefit of U.S. Provisional Application No. 62/068,799 filed Oct. 27, 2014, which is incorporated herein by reference for all purposes.
- This application is directed to thermostats for use with heating, ventilation, and air conditioning systems, and more particularly, to a magnetically-mounted wall thermostats, systems, and methods.
- Wall mounted thermostats that are used to control heating ventilation air conditioning (HAVC) units have been used for decades. These conventional wall mounted thermostats are typically anchored to the wall by screws, bolts or by being snapped into an in-wall housing that is anchored to the wall, in an air conditioned area that is to be controlled by the thermostat. Though the capabilities and accessibility of thermostats in general have changed rapidly over the last few years due to advancements in increased capabilities of micro controllers and size reduction, the way in which thermostats are attached to the wall has basically remained unchanged. This is probably due in part to advancements in technology that allow users to remotely control their thermostats through a computer, tablet, smart phone, or similar device. By using one or more of these various computerized smart devices, a user can access the thermostat and make various changes to the thermostat's settings (e.g., changing the temperature setting, obtaining information from the thermostat, etc.) without being in the same building as the thermostat. Thus, there is little motivation to change the way in which thermostats are attached to a wall of the structure in which the thermostat is situated.
- One aspect of this disclosure provides a thermostat that can be magnetically attached to the wall using one or more magnets that allow the thermostat to be rotated about the wall, once mounted, or easily removed from the wall altogether to operate as a remote unit. Unless otherwise indicated, as used throughout this document, “or” does not require mutual exclusivity. This unique configuration provides advantages over more permanent conventional anchoring systems that have been used to anchor the thermostats to a wall. For example, the presence of the magnets allows the thermostat to be rotated about the wall to change the general orientation of the thermostat, which can be helpful in physically tight locations, such as adjoining walls or adjacent door moldings that would otherwise prevent the thermostat from being placed in that particular location. Additionally, the rotation allows the user to rotate the thermostat from a landscape orientation to a portrait orientation for aesthetic reasons, if desired. Further, this easy release design allows the thermostat to function as a remote sensor, so that the user can take the thermostat into a different room, which would then adjust the operation of the HVAC unit to attempt to change the temperature of the room in which the remote thermostat and the user is presently located, and thereby making the user more comfortable.
- According to one illustrative embodiment, a magnetically mounted wall thermostat for use as part of a heating, ventilation, and air conditioning (HVAC) system includes a thermostat housing having a first side and a second side. The thermostat housing includes a display on the first side of the thermostat housing to present visual indicia and to receive user inputs and includes a back plate on the second side of the thermostat housing. The back plate is coupled to the display. The magnetically mounted wall thermostat further includes a wall mounting base having a first side and a second side. The first side of the wall mounting base is disposed adjacent to the second side of the thermostat housing when the magnetically mounted wall thermostat is in a mounted position. The second side of the wall mounting base is disposed adjacent to a wall in a volume in which conditioned air is desired. The magnetically mounted wall thermostat further includes a releasable magnetic coupling having a first member and a second member. The first member is coupled to the second side of the thermostat housing and the second member is coupled to the first side of the wall mounting base. At least one of the first member and second member is a magnet and in many embodiments they both are. The magnetically mounted wall thermostat may also include a signal coupling formed between the thermostat housing and the wall mounting base.
- According to another illustrative embodiment, a magnetically mounted wall thermostat for use as part of a heating, ventilation, and air conditioning system includes a thermostat housing having a first side and a second side. The thermostat housing includes a display on the first side of the thermostat housing to present visual indicia and to receive user inputs and a back plate on the second side of the thermostat housing. The back plate is coupled to the display. The magnetically mounted wall thermostat further includes a wall mounting base having a first side and a second side. The first side of the wall mounting base is disposed adjacent to the second side of the thermostat housing when the magnetically mounted wall thermostat is in a mounted position and the second side of the wall mounting base disposed adjacent to a wall in a volume in which conditioned air is desired. The magnetically mounted wall thermostat also includes a magnetic coupling means for coupling the thermostat housing and the wall mounting base to provide for rotational movement and release with a parting force greater than a threshold force.
- According to another illustrative embodiment, a thermostat for use as an aspect of a heating ventilation and air conditioning system includes a base unit that is coupled to a wall in a room of a building that is to receive conditioned air. The base unit has a first side that faces away from the wall and a second side that faces the wall. The thermostat further includes a display unit that includes a display for presenting visual indicia to a user. The display unit has a first side and a second side. The display is on the first side of the display unit and the second side of the display unit is adjacent to the first side of the base unit when in a mounted position. The thermostat also includes a releasable and rotatable coupling formed between the base unit and the display unit that allows the display unit to rotate relative to the base unit and allows the display unit to be released from the base unit when a separation force is applied greater than a separation threshold. The releasable and rotatable coupling includes at least a first magnet attached to first side of the base unit and at least a second magnet attached to the second side of the display unit whereby the first magnet and the second magnet develop a magnetic force holding the base unit and display unit proximate to one another when the base unit and display unit are in the mounted position.

FIG. 1A presents one illustrative embodiment of a magnetically wall mountedthermostat 100 of this disclosure that is for use as an aspect of a heating, ventilation, and air conditioning (HVAC) system. Thethermostat 100 includes a screen or display 105 that is attached to aback plate 110, that together form athermostat housing 112, or display housing. Thethermostat housing 112 has a first side 113 (or front side) and a second side 114 (or back side). Thedisplay 105 is on thefirst side 113 and theback plate 110 is on thesecond side 114. Thedisplay 105 may be used to present visual indicia, such as temperature set point, actual temperature, mode of operation, etc. to users and to receive user input from a touch screen, physical device associated with the screen, or wireless signal. - The
back plate 110 has a mountingarea 115, in which one ormore magnets 120 are located. Both the mountingarea 115 and themagnets 120 are shown, as dashed circles, indicating that they lie behind thescreen 105, i.e., on the second side 114 (back side) of thethermostat housing 112. The mountingarea 115 is the area of theblack plate 110 that is utilized to mount thethermostat housing 112 to a wall plate, as described below. In one illustrative embodiment, the mountingarea 115, is afeature 125 that protrudes from the surface of theback plate 110, as generally shown inFIG. 1B , or in another illustrative embodiment, it is arecess 130 formed in the surface of theback plate 110, as generally shown inFIG. 1C . Other arrangements, such as flat, may be used. Though the mountingarea 115 is shown to be circular, it should be understood that other geometric configurations may also be employed, such as a square, hexagonal, or octagonal shapes, provided, the geometric configuration is able to rotate in a circular direction with respect to awall base 135, as generally illustrated inFIGS. 1D and 1E . - The
magnets 120 may be used to couple theback plate 110 to other portions of thethermostat housing 112 as described herein. In other embodiments, glue, physical fasteners, press fit or interference fit or other technique may be used. Themagnets 120 may also be used to attract and releasably hold awall mounting base 135. Thedisplay 105 andback plate 110 form thethermostat housing 112 that may form an interior portion with various electronic components therein as desired. - The
thermostat housing 112 is releasably and moveably coupled to thewall mounting base 135 using a releaseable magnetic coupling 315 (FIG. 3 ). In this way, thethermostat housing 112 may be twisted or rotated vis-à-vis thewall mounting base 135 or force separating thethermostat housing 112 andwall mounting base 135 may be generated to allow them to be displaced one from another. In one illustrative embodiment, thethermostat housing 112 is mountable to thewall base 135, as shown inFIGS. 1D, 1E, and 2A . Thewall base 135 has a first side (front side) 136 and a second side (back side) 137. Thefirst side 136 of thewall mounting base 135 is disposed adjacent to thesecond side 114 of thethermostat housing 112 when the magnetically mountedwall thermostat 100 is in a mounted position, i.e., in position on a wall, and thesecond side 137 of thewall mounting base 135 is disposed adjacent to the wall in a room or volume in which conditioned air is desired. - The
wall base 135 includes awall mounting area 140 that corresponds to the mountingarea 115 of theback plate 110 of thethermostat 100 and may also have one ormore magnets 145 located within the mounting area. Depending on the configuration of the mountingarea 115 of theback panel 110, in one illustrative embodiment, thewall mounting area 140 is afeature 150 that protrudes from the surface of thewall base 135, or in another illustrative embodiment, thewall mounting area 140 is arecess 155. Thus, if the mountingarea 115 of theback panel 110 is theprotruding feature 125, thewall mounting area 140 of thewall base 135 will be therecess 155 into which theprotruding feature 125 can be received when thethermostat 100 is attached to thewall base 135. Alternatively, if the mountingarea 115 of theback panel 110 is therecess feature 130, the mountingarea 140 of thewall base 135 will be theprotruding feature 150 that will be received within therecess feature 130 when thethermostat 100 is attached to thewall base 135. In this way, thethermostat housing 112 andwall mounting base 135 cooperate to be mated. In one illustrative embodiment, thewall mounting base 135 may include anoptional wall plate 160, which can be used to cover a larger opening in the wall if present. - A releasable magnetic coupling 315 (shown clearly in
FIG. 3 ) may be used to releasably and moveably couple thethermostat housing 112 to thewall mounting base 135. The releasablemagnetic coupling 315 includes afirst member 316 and asecond member 318. Thefirst member 316 may be a magnet or plurality of magnets and thesecond member 318 may be another magnetic with correct polarity to be attracted to thefirst member 316 or could be a metal member or other magnetically attractive member. Alternatively, thefirst member 316 may be a metal member or other magnetically attractive member and thesecond member 318 may be a magnet. Whether magnet and magnetically attractive member or magnetic and magnet, thefirst member 316 andsecond member 318 cooperate to form a magnetic force therebetween when in close proximity as would be the case in the mounted position. Thefirst member 316 is coupled to thesecond side 114 of thethermostat housing 112 and thesecond member 318 is coupled to thefirst side 136 of thewall mounting base 135. At least one of thefirst member 316 andsecond member 318 comprises a magnet. Any magnetic material may be used for the magnets described herein. Non-limiting examples include rare-earth magnets or ferromagnetic materials. - As noted above, either one or both of the
thermostat 100 and thewall base 135 include one ormore magnets wall mounting base 135 will have a magnet centrally located within either the mountingarea 115 or mountingarea 140. In such embodiments, whichever of thethermostat 100 orwall mounting base 135 that does not include the single magnet, the other will have a metal plate or be constructed of a material, at least within the mounting area, such that the opposing component will be magnetically attracted to the magnet, causing the opposing component and the magnet to be magnetically coupled together. At the same time, the magnetic coupling will allow relative rotational movement and under a separation for force, release from each other. Many embodiments are possible. - For example, in one embodiment, the
wall base 135 may have two or four (or some other number) magnets 145 (or second member 318 (FIG. 3 )) and thethermostat housing 112 may have metal members, metal plates, or another magnet (first member 316) that are positioned to interface with thefirst magnets 145 to releasably and moveably hold thethermostat housing 112 to thewall base 135. Themagnets 145 may be attached using an adhesive or any technique to couple the magnet or magnets to the desired location. In one embodiment, thewall base 135 may be formed with tracks (or physical slots) to help locate the magnets during manufacture. With these various arrangements, thedisplay 105, which is part of thethermostat housing 112, and thewall base 135 may be moved (twisted, or rotated) relative to each other with any degrees of difference or may be pulled normal to the wall to release thethermostat housing 112 andwall base 135. - In an illustrative embodiment, both the
thermostat 100 and thewall mounting base 135 each have a plurality of magnets (or alternatively metal plates on one side) located within their respective mountingareas areas areas display housing 112 can be readily rotated with respect to thewall mounting base 135 in a portrait (length ofdisplay housing 112 is oriented vertically) position, as seen inFIG. 2A or a landscape (length ofdisplay housing 112 is oriented horizontally) position, as seen inFIG. 2B . Other magnet positions and numbers may be used as well as combinations of magnets and metal (or magnetically attractive) plates. In yet another illustrative embodiment, each of thethermostat 100 and thewall mounting base 135 have two pairs of magnets that are spaced 180° apart that also allow the above orientations to be achieved. This not only allows for thedisplay housing 112 to be placed in different orientations for convenience or aesthetic purposes, but this unique feature also allows thedisplay housing 112 to be easily removed from thewall mounting base 135, if desired. The greater number of magnets that are present, the greater holding power. Though four magnets are shown on each of thedisplay housing 112 and thewall mounting base 135, more than four magnets can be used on each thedisplay housing 112 and thewall mounting base 135, if desired, thereby further increasing the holding power. Some embodiments may have fewer magnets. -
FIG. 3 illustrates a partial sectional view of one illustrative embodiment in which the mountingarea 115 of thedisplay housing 112 is a protrudingbase area 305 and the mountingarea 140 of thewall mounting base 135 is a recessedarea 310. As discussed above, this configuration may be reversed, or in an alternative illustrative embodiment, both mountingareas - The
thermostat housing 112 and thewall mounting base 135 include a quick or easy connect/disconnect interface 146, or signal coupler, that provide electrical connection between thedisplay housing 112 andwall mounting base 135, for communication or power, while allowing for the two to be easily separated from one another when the user exerts sufficient pulling force to separate the magnets from one another. Furthermore, thequick connect 146 may allow for a twisting or rotational motion between thewall base 135 anddisplay 105. For example, in one illustrative embodiment, the connect/disconnect interface may be a quick release electrical connector pair located on ends of small cables that extend from each of thedisplay housing 112 and thewall mounting base 135. - Another example is a surface electrical contact system, as generally shown in
FIGS. 4A and 4B . In this illustrative embodiment,concentric circles 405 of a conductive metal, such as copper, are located in the center of the mountingarea 140 of thewall mounting base 135, while conductive contact points 410 are arranged on the mountingarea 115 of theback panel 110 of thedisplay housing 112 to contact the surface of theconcentric circles 405 in a way to provide electrical current or signals to thedisplay housing 112. Theconcentric circles 405 are connected to a main electrical source by wires that run from the electrical source to thewall mounting base 135. Those skilled in the art, given this disclosure, would understand how to connect the two devices to provide electrical connection to run a HVAC system. This particular illustrative embodiment provides a very convenient way in which thethermostat housing 112 of thethermostat 100 is electrically coupled to thewall mounting base 135. If a user chooses to remove thethermostat housing 112 from the wall, the user merely exerts sufficient pulling force to overcome the attraction of the opposingmagnets display housing 112 is quick and easy for the user. Furthermore, in some other illustrative embodiments, the circuitry includes a safety removing controller that automatically disconnects the supply voltage from the surface contacts to prevent electric shock when the unit is removed from thewall mounting base 135. -
FIG. 5 illustrates an exploded view of one illustrative embodiment of thewall mounting base 135. As seen in this embodiment, thewall mounting base 135 comprises afront panel 505, aback panel 510 attachable to thefront panel 505, which form a housing, and anelectronic circuit board 515 located between the front andback panels electronic circuit board 515 include various electronic components andcircuitry 520, such as amicroprocessor 525,controller 530,memory 535, Wi-Fi communication circuitry 540, including an antenna, or atemperature sensor 545, all of which are electrically coupled together in a functional manner as schematically shown. Thesevarious components 520 are used to drive or provide data to the display 105 (FIG. 1 ) and display various types of information on the display 105 (FIG. 1 ) and receive input requests or commands from the user directly or through a remote interface, such as a smartphone, computer, tablet or other similar types of smart devices. As explained below, in some embodiments, at least a portion of these components are located within thedisplay housing 112, so that the thermostat's functions can either be achieved optionally through either thewall mounting base 135 or thedisplay housing 112. -
FIG. 6 presents an illustrative embodiment of electronic circuitry that may be located within thethermostat housing 112. This embodiment may comprise one or more of amicroprocessor 605, apower supply 610,communications circuit 615, anantenna 620,memory 625, which may be separate from or form a part of themicroprocessor 605, anexternal interface port 630, as such a USB port, atemperature sensor 635, avideo camera 640, and an audio circuit andspeaker 645, all of which are electrically coupled in a functional manner, as generally illustrated. It should be understood thatFIG. 6 is merely a schematic diagram of one embodiment that shows the various optional components and that the one or more components may be packaged together in a manner known to those skilled in the art. Further, the listed components are not exhaustive and other components may also be included to provide additional utility to thethermostat 100 or thethermostat housing 112. As one skilled in the art will appreciate, some components may be omitted and others added. - When the
display housing 112 includes one or more of the above-listed components, the thermostat may have increased utility to the user. For example, when thedisplay housing 112 is removed from thewall mounting base 135 and thetemperature sensor 635 is present, thedisplay housing 112 functions as a remote thermostat that can be carried by the user from room to room. So, if the user enters a room, that due to its distant location from thewall mounting base 135, is warmer than the air at thewall mounting base 135, thetemperature sensor 635 will sense the increase temperature and send a command to the HVAC unit to provide additional cooling until thetemperature sensor 635 is cooled to the set, thereby making the user more comfortable at the user's location. In such embodiments, the temperature sensor's 635 is communicated from thethermostat housing 112 by way of thecommunications circuit 615 andantenna 620, and the power for the continued operation of thethermostat housing 112, when separated from the main power supply at thewall mounting base 135, is provided by thepower supply 610, which in one illustrative embodiment is a rechargeable battery. The temperature sensor's 635 signal may be communicated to thewall mounting base 135, which in turn, transmits the signal to the HVAC controller, or the temperature sensor's 635 signal may be transmitted directly to the HVAC controller by Wi-Fi. Themicroprocessor 605 and thememory 625 provide adequate processing power and programming to control the operation of the various components and may work in conjunction with or separate from the circuitry of thewall mounting base 135. - In addition to the
thermostat housing 112 receiving programming instructions and other data wirelessly, in one illustrative embodiment, it receives data via theexternal interface port 630. Either of these data links allows various types of data to be transmitted to and electronically stored in the memory of thethermostat housing 112, including personalized photographs or videos. Thus, with the easy removal function of thethermostat housing 112 from thewall mounting base 135, thedisplay housing 112 can also function as an electronic picture frame that can either scroll various pictures or display a static picture, or play videos as part of the visual indicia on the display. With the electronic circuitry that can be included within the device, thedisplay housing 112 can function similarly to that of a smart tablet, including even browsing the internet with a Wi-Fi connection. - In another illustrative embodiment, the
thermostat housing 112 also includes thevideo camera 640 that together with the Wi-Fi capability can allow the user to communicate with others over the internet. For example, if the user is experiencing HVAC operation problems, the user can use the video camera to speak face-to-face with a service representative. Additionally, the video camera may operate as a facial recognition sensor so the HVAC will operate in a certain programmed or prescribed manner when a particular user is sensed by the video camera. - In yet another illustrative embodiment, the
thermostat housing 112 also includes the audio circuit andspeaker 645 that allow the user to input audible instructions into thedisplay housing 112 by way of voice commands and receive voice inquiries or other statements from thedisplay housing 112. Thethermostat 100 may also interface with household integration control devices. - In embodiments presented herein, the
display 105 and thewall mounting base 135 allow rotation, or twisting, while remaining in their given planes, whereby the thermostat display may assume a horizontal or vertical position without changing the physical mounting bracket on the wall. In addition, thedisplay 105 andwall mounting base 135 may have a separating force applied, e.g., a force pulling thedisplay 105 away from the wall, to separate the two. In this case, thedisplay 105 may be carried by a user to different locations and used a remote control. In some embodiments, the temperature sensor or humidity sensor may be in coupled to thewall mounting base 135 or thedisplay 105. In still another embodiment, duplicate temperature or humidity sensors may be included so that thedisplay 105 andwall mounting base 135 both have a temperature sensor or humidity sensor associated therewith. When the sensors remain on the wall, it may provide a more stable measurement environment. Communication between the sensors and the display may be by a wireless interface. - When the
display 105 is proximate thewall mounting base 135, thedisplay 105 may receive power by wireless charging, e.g., inductive charging or by physical contacts. - Referring now primarily to
FIG. 7 , which is an exploded, perspective view, another illustrative embodiment of a magnetically mountedwall thermostat 700 for use as part of a heating, ventilation, and air conditioning system is presented. The magnetically mountedwall thermostat 700 includes athermostat housing 702 having adisplay 704 and aback plate 706. Thethermostat housing 702 has a first side 708 and asecond side 710. Thedisplay 704 is operational to present visual indicia on the first side 708, which is also the first side of thedisplay 704, and thedisplay 704 also functions to receive user control inputs, such as change of temperature. Various electronics or electrical components 714 are included in an interior portion of thethermostat housing 702. - The
display 704 has a first side 716 and asecond side 718. Theback plate 706 has afirst side 720 and asecond side 722. Thesecond side 718 of thedisplay 704 may be coupled to thefirst side 720 of theback plate 706 using magnets analogous to the discussion in connection withFIGS. 1B and 1C above or may be press fit, glued, or held by any other coupling technique to form thethermostat housing 702. Amagnetic holder 724 may be attached to thesecond side 722 of theback plate 706. Themagnetic holder 724 includes at least one magnet that is used to attract a magnetic member 726, such a magnetic ring 728. Themagnetic holder 724 also may include one or more coils (not explicitly shown) for wireless charging as will be described further below. - The magnetically mounted
wall thermostat 700 also includes awall mounting base 730. Thewall mounting base 730 includes the magnetic member 726, various electronics orelectrical components 732, and awall attachment member 734, or wall plate. Thewall attachment member 734 may house various electronics or electrical components. Thewall mounting base 730 has afirst side 736 and asecond side 738. The magnetic member 726 may have a feature 740 that is aprotrusion portion 742 that is sized and configured to mate with arecess 744 formed as an aspect of themagnetic holder 724 of thethermostat housing 702. In another embodiment, the protrusion may be on thethermostat housing 702 and the recess on the magnetic member 726. The magnetic member 726 may include at least one magnet for attracting themagnetic holder 724 when adjacent in the mounting position or themagnetic holder 724 may have at least one magnet to attract the magnetic member 726 or both may have at least one magnet. The magnetic member 726 may also include one or more coils (not explicitly shown). The one or more coils of the magnetic member 726 and one or more coils of themagnetic holder 724 may be excited to charge an electrical storage device associated with thedisplay 704. - In one embodiment, a
perimeter ring 746 is sized and configured to mate within arecess 749 formed within a portion of thewall attachment member 734. The magnetic member 726 may be held to thewall attachment member 734 by mechanical fasteners, glue, snap fit, or attachment techniques. Thevarious electronics 732 may be disposed within an interior created using the magnetic member 726 andwall attachment member 734. - In this illustrative embodiment, a releasable magnetic coupling having a
