The present invention relates in general to a self-contained, self-regulating intelligent automated window treatment with increased energy efficiency.
There is no admission that the background art disclosed in this section legally constitutes prior art.
There have been many different types and kinds of motorized window treatments. For example, reference may be made to U.S. Pat. Nos. 5,413,161; 5,532,560; 8,299,734 B2; 8,525,462 B2; 8,659,246 B2; 8,851,141 B2; 8,950,461 B2; and 9,045,939 B2.
The use of integrated technological systems in buildings (both home and commercial) is one of the most significant new trends in digital innovation. Transitioning to a smarter building can improve the building occupant's control over every aspect of how the building operates, and increase the safety, energy efficiency, and accessibility of it as well. Smart building systems and devices often operate together, sharing consumer usage data among themselves and automating actions based on the building occupants' preferences.
The U.S. Department of Energy has stated that “When properly installed, window shades can be one of the simplest and most effective window treatments for saving energy” and advises that “You should lower shades on sunlit windows in the summer. Shades on the south side of a house should be raised in the winter during the day, then lowered during the night.” https://www.energy.gov/energysaver/energy-efficient-window-treatments.
Energy efficiency can only be achieved if the window shades are raised or lowered to the optimal positions as environmental conditions change. This is a challenge with manual treatments and non-automated motorized treatments, it is unlikely to be done when the building occupant is absent, and it is an inconvenience to the building occupant to constantly adjust the window treatments when present. Thus these adjustments are often not done when needed. Furthermore, the majority of commercially available automated motorized window treatments are ideal for large office buildings, where environmental sensors can be mounted on the roof of the building. Although this allows for accurate environmental readings, this placement of sensors is less than ideal for many small commercial and residential buildings.
Thus there currently is a need for an automated motorized window treatment with increased energy efficiency that (1) allows for maximum light harvesting for the health of the building occupants; (2) allows for heat control by incremental movement of the shade with respect to sun position; (3) requires minimal effort from the building occupant; (4) is easy to install; and (5) is designed for use in small commercial and residential buildings.
The present invention relates in general to a self-contained, self-regulating intelligent automated window treatment with increased energy efficiency. In particular, in accordance with one embodiment, the invention relates to a self-contained, self-regulating intelligent automated window treatment with increased energy efficiency consisting of: (1) a headrail; (2) a tube located within the headrail; (3) a motor located within the headrail, preferably within the tube; (4) window treatment fabric with one terminus of the fabric affixed to the tube within the headrail, and with the fabric extending from the tube and out from the headrail; (5) a smart bottom rail attached to the terminus of the shade fabric furthest from the tube with the bottom rail containing, at least one sensor, at least one control button, and a battery that provides power to the sensor(s) and control button(s), and wherein the smart bottom rail communicates with the motor in the headrail. Types of sensors used may include environmental sensors, motion sensors, and inertial sensors. The environmental sensors may provide information that may be used to determine when the window treatment motor should automatically raise and lower the fabric and bottom rail of the window treatment with minimal effort from the user. The automatic adjustment of the position of the fabric and bottom rail of the window treatment may allow for a reduction of energy consumption by the user by decreasing the need for artificial lighting, heating, and air conditioning. The motion sensors may provide information regarding occupancy of the room in which the window treatment is located. This information may be used to automatically adjust the fabric and bottom rail of the window treatment according to user preferences. The inertial sensors may provide information regarding the movement of the fabric and bottom rail of the window treatment. This information may be used to automatically stop the movement of the fabric and bottom rail of the window treatment if it comes into contact with an object within the path of movement of the fabric and bottom rail of the window treatment.
In another embodiment of the invention, the battery in the bottom rail may be a rechargeable battery. In a further embodiment, the bottom rail may contain at least one solar panel, which may be used to provide charge to the rechargeable battery.
In another embodiment of the invention, the headrail further consists of a solar panel and a rechargeable battery that may be charged by the solar panel. In a further embodiment solar power stored in the rechargeable battery of the bottom rail may be transferred to the rechargeable battery-powered motor of the headrail.
The features of this invention and the manner of attaining them will become apparent, and the invention itself will be best understood by reference to the following description of certain embodiments of the invention taken in conjunction with the accompanying drawings.
It will be readily understood that the components of the embodiments as generally described and illustrated in the drawings herein, could be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the system, components and method of the present invention, as represented in the drawings, is not intended to limit the scope of the invention, as claimed, but is merely representative of the embodiments of the invention.
Embodiments of the present invention provide a self-contained, self-regulating intelligent automated motorized window treatment with increased energy efficiency, wherein the window treatment is suitable for use in a small commercial or residential building.
In one embodiment of the invention a self-contained, self-regulating intelligent automated motorized window treatment with increased energy efficiency is a window treatment consisting of: (1) a headrail; (2) window treatment fabric with one terminus of the fabric affixed to a tube, and wherein the tube is located in the headrail; (3) a motor located in the headrail; (4) a smart bottom rail attached to the window treatment fabric at the fabric terminus opposite to the headrail terminus, and wherein the smart bottom rail communicates with the motor in the headrail; (5) at least one control button located on the smart bottom rail that may be used to raise or lower the position of the window treatment fabric and the bottom rail or to set a favorite position for the window treatment fabric and the bottom rail, and wherein the control button may be a physical button or an icon on a touch screen; (6) at least one sensor located on the smart bottom rail that may be selected from the group consisting of: environmental sensors (such as light sensors, temperature sensors, ultra violet light sensors, or humidity sensors); motion sensors (such as an occupancy sensor); and inertial sensors (such as accelerometers, gyroscopes, or magnetometers); and (7) a battery in the bottom rail to power the control buttons and sensors. The battery in the bottom rail may optionally be a rechargeable battery. The smart bottom rail may optionally contain at least one solar panel on the window-facing side of the smart bottom rail to provide power for the rechargeable battery of the smart bottom rail. Additional sensors may optionally be located on the headrail.
The inclusion of buttons directly upon the self-contained, self-regulating intelligent automated motorized window treatment will allow a user in close proximity to the window treatment greater freedom to control the window treatment at the moment a need for adjustment is noticed without requiring the user to locate a remote control or a smart device that may be used to direct the adjustment of the window treatment fabric and bottom rail position. This convenience will increase the energy efficiency of the window treatment.
The environmental sensors may provide information that may be used to determine when the window treatment motor should automatically raise or lower the position of the window treatment fabric and bottom rail with minimal effort from the user. The automatic adjustment of the window treatment fabric and bottom rail may allow for a reduction of energy consumption by the user by decreasing the need for artificial lighting, heating, and air conditioning. The motion sensors may provide information regarding occupancy of the room in which the window treatment is located. This information may be used to automatically adjust the position of the window treatment fabric and bottom rail according to user preferences. The inertial sensors may provide information regarding the movement of the window treatment fabric and bottom rail. This information may be used to automatically stop the movement of the window treatment fabric and bottom rail if either comes into contact with an object within the path of movement of the window treatment fabric or bottom rail.
The inclusion of environmental sensors within the self-contained, self-regulating intelligent automated motorized window treatment is an improvement over the current use of separate external sensors that are difficult to mount in an ideal location and are an unattractive addition to a window or it's surrounding area.
The smart bottom rail may communicate with the motor by any acceptable communication means, including, but not limited to, RF wireless, Bluetooth radio technology, piezoelectric RF technology, printed ink conductive line on the shade fabric, or conductive thread woven in the shade fabric.
In another embodiment of the invention, the headrail further consists of a solar panel and a rechargeable battery to power the motor, wherein the rechargeable battery may be charged by the solar panel. In a further embodiment solar power stored in the rechargeable battery of the bottom rail may be transferred to the rechargeable battery of the headrail.
In further embodiments of the above-described embodiments of the invention, the window treatment will include a charging and/or data transfer port, such as a universal serial bus (USB) port on the bottom rail and/or the headrail.
In another embodiment of the invention, a self-contained, self-regulating intelligent automated motorized window treatment with increased energy efficiency is a window treatment consisting of a headrail, window treatment fabric with one terminus of the window treatment fabric affixed to a tube, a smart bottom rail, a rechargeable battery-powered motor located within the headrail that communicates with the smart bottom rail attached to the window treatment fabric at the terminus opposite to the headrail terminus, at least one solar panel, a solar powered rechargeable battery, at least one sensor, at least one wireless charging transmitter, and at least one wireless charging receiver.
