The present invention relates generally to sanitary devices, and more specifically, to toilet paper dispensers.
Commercial, residential, healthcare and industrial spaces typically have restroom spaces for human occupants. Sanitation is a primary concern within these spaces. These spaces may contain various devices to offer supplies allowing users to maintain an acceptable level of sanitation.
A smart toilet paper dispenser comprises a powered paper dispenser, an enclosure, a plurality of drawers, and a top surface. The smart toilet paper dispenser receives user input and in response dispenses a predetermined amount of paper. The user input is motion detected by a motion sensor, a voice command detected by a microphone, or touch detected by a push button. A switch allows a user to select at least one of a plurality of different paper lengths the smart toilet paper dispenser will dispense. The top surface comprises a non-slip surface and includes a plurality of ridges and a raised perimeter to prevent items placed thereupon from rolling. The top surface includes a groove large enough to accommodate a user's device. In one embodiment, a storage drawer is provided. In another embodiment, a storage drawer and a trash receptacle drawer are provided. A novel smart toilet paper dispenser allows easier, touchless operation of the device and removes one touchpoint by which pathogens are transmitted.
The novel smart toilet paper dispenser comprises a powered paper dispenser that is partially or entirely covered by an enclosure. The enclosure includes a top section which comprises a plurality of drawers and a top surface. One drawer is configured to dispense small trash bags. Another drawer is configured to hold medical supplies, sanitary supplies, feminine hygiene products, or other supplies that may be necessary in a restroom. The top surface covers at least the entire area of the top of the smart toilet dispenser. In one embodiment, the top surface is formed from a non-slip surface. The top surface includes a plurality of ridges and a raised perimeter to prevent items placed upon it, such as medical supplies or a user's personal effects, from moving around or rolling over the edge onto the ground. The top surface also includes a groove deep and wide enough to accommodate a user's device such as a smartphone, tablet, or other device.
The novel smart toilet paper dispenser dispenses paper in response to user input. User input is received in one of three ways: motion, touch, or voice command. The user input is detected by a motion sensor, a microphone, or a push button. The detection device then transmits a signal to a microcontroller which controls a motor to rotate. The motor turns a feed roller which causes paper to dispense out through the bottom of the dispenser. In one embodiment, the novel smart toilet paper dispenser dispenses one of two predetermined amounts of paper. In another embodiment, more than two lengths of paper are selectable. In another embodiment, the length of paper dispensed is not selectable. In yet another embodiment, the length of paper dispensed is fixed.
In one embodiment, the novel smart toilet paper dispenser also includes a night light disposed on the bottom of the smart toilet paper dispenser. The light is connected to a switch with three positions, “On,” “Off,” and “Motion.” In the “On” position, the night light will remain on, illuminating the space below the smart toilet paper dispenser. In the “Off” position, the light will not illuminate. When the switch is in the “Motion” position, the light will illuminate in response to a user input. In another embodiment, the night light is disposed in a location other than the bottom of the smart toilet paper dispenser.
The smart toilet paper dispenser includes an LED strip light disposed on the front face of the dispensing mechanism that displays the status of the smart toilet paper dispenser. For example, when the smart toilet paper dispenser is dispensing paper, the LED strip light will flash blue, and when the smart toilet paper dispenser is empty, the LED strip light will flash red.
A smart toilet dispenser allows a user to acquire toilet paper without physical interaction with the smart toilet dispenser. A user that is physically unable to push a button located on the smart toilet paper dispenser, or unable to wave their hand or other appendage to trigger a motion sensor, can still cause the smart toilet paper dispenser to dispense paper by speaking a voice command. The smart toilet paper dispenser allows touchless operation of the device, removing one of the touchpoints by which pathogens and other contaminants may be transmitted. A smart toilet paper dispenser allows users unable to physically trigger the dispensing mechanism to trigger the dispensing mechanism by other means.
Further details and embodiments and methods are described in the detailed description below. This summary does not purport to define the invention. The invention is defined by the claims.
The accompanying drawings, where like numerals indicate like components, illustrate embodiments of the invention.
Reference will now be made in detail to some embodiments of the invention, examples of which are illustrated in the accompanying drawings.
In the description and claims, terms such as “clockwise (CW)”, “counterclockwise (CCW)”, “top”, “bottom”, “front”, “back”, and “side” are used to describe relative directions and orientations between different parts of the novel smart toilet paper dispenser, and it is to be understood that the overall structure being described can actually be oriented in any way in three-dimensional space. For example, when a first object is described as rotating counterclockwise, it is to be understood that the first object may in fact be rotating clockwise when viewed from a different perspective.
The toilet paper dispenser 100 is activated by user input generated by one of the following: activating a first motion sensor 159, pushing the paper advance button 152, or issuing a voice command which is then received by the microphone 174. One of two lengths of paper is then dispensed by the toilet paper dispenser 100, either a long length or a short length. The length of paper dispensed is selected by the position of paper length switch 153. In one embodiment, after paper is dispensed a user cuts the dispensed paper using the paper cutter 155. In another embodiment, the paper dispensed by paper dispenser 150 is perforated. In yet another embodiment, paper cutter 155 is not present.
The LED strip light 156 displays various colors and patterns to inform a user or maintenance technician about the status of the toilet paper dispenser 100. In one embodiment, the LED strip light 156 toggles between outputting a variety of colors in a flashing mode or solid mode depending on status. For example, when the access panel 105 is in the open position, the LED strip light 156 is solid red. When the toilet paper dispenser 100 is dispensing paper, the LED strip light 156 is flashing blue. When the paper roll 157 is empty, the LED strip light 156 is flashing red. When the toilet paper dispenser 100 is ready to accept a user input (also called standby mode), the LED strip light 156 is solid blue. When the smart toilet paper dispenser is powered off, the LED strip light 156 is off.
In one embodiment, The access panel 105 is connected to the base 151 and connected to the paper dispenser 150 with an operable latch 111 (see
The access panel 105 allows access to the interior of the enclosure 101. In this embodiment, the access panel 105 is manufactured to be large enough to permit the paper roll 157 to be changed when the access panel 105 is in the open position.
The first motion sensor 159 is disposed on the base 151 of the paper dispenser 150. The first motion sensor 159 is disposed in front of the feed roller 158 and behind access panel 105. When the first motion sensor 159 detects a user's motion, the first motion sensor 159 generates and transmits a signal to the paper dispenser circuit 170 to dispense paper (see
The paper dispenser 150 contains the components to detect a user input and to dispense paper in response to that user input. When the toilet paper dispenser 100 detects a user input, the feed roller 158 rotates. In one embodiment, the paper roll 157 is connected to support arm 161 directly in a manner that allows paper roll 157 to spin freely. In another embodiment, a support rod connected to support arm 161 extends through the center of paper roll 157 allowing paper roll 157 to spin freely around the support rod. In yet another embodiment, a second support arm may connect directly to the opposite side of the paper roll 157 and allow paper roll 157 to spin freely. The roll of paper disposed on paper roll 157 has one connected end attached to the roll's tubular base. The paper is wound around the tubular base. A free end of paper extends from the circumference of the roll. The free end of the paper disposed on paper roll 157 is in contact with feed roller 158. When the feed roller 158 rotates, paper is drawn from the paper roll 157, over feed roller 158, and out through opening 162 (see
The first motion sensor 159 detects a user's motion and generates a motion detect signal. A paper dispenser circuit 170 is coupled to receive the motion detect signal, and in response, controls the feed roller 158 to rotate and dispense paper. As the feed roller 158 rotates, paper roll 157 is unrolled and paper exits through opening 162 (see
The top surface 104 is a non-slip surface. It includes a plurality of ridges, one of which is indicated by reference numeral 107, that provide further resistance to unwanted movement of items placed upon it. The raised perimeter 108 prevents items from rolling and falling over the edge. A user may place a variety of items on top surface 104, such as keys or medical items. The groove 109 is made deep and wide enough to accommodate a user device, such as a smartphone or tablet in an upright position.
The opening 162 is of sufficient width to permit toilet paper to pass through it. The opening 162 provides a passage for toilet paper from paper roll 157 within the enclosure 101 and out through the base 151. The three position switch 163 has three selectable positions: “Off,” “On,” and “Motion.” When the three position switch 163 is in the “On” position, the light 164 will remain illuminated. When the three position switch 163 is in the “Off” position, the light 164 will not illuminate. When the three position switch 163 is in the “Motion” position, the light 164 will illuminate when a user activates the second motion sensor 176. When On/Off button 182 is pressed, On/Off button 182 generates and sends a signal to microcontroller 171 (see
When a toilet paper dispenser 100 is installed and powered on, and paper roll 157 is full of paper, the toilet paper dispenser 100 is ready for operation. Microcontroller 171 will receive a signal from paper position sensor 160 indicating the paper roll 157 is sufficiently full and does not need to be changed. The microcontroller 171 will send a signal to LED strip light 156 to display a solid blue color, indicating standby mode to a user. Components receive power from power supply 172. In one embodiment, power supply 172 is a non-rechargeable, replaceable battery. In another embodiment, power supply 172 is a rechargeable battery. In another embodiment, power supply 172 is a connection to an external power source such as mains power or low voltage power.
To activate the toilet paper dispenser 100, a user will provide one of three inputs. When the first motion sensor 159 detects a user's motion, first motion sensor 159 generates and communicates a motion detect signal to microcontroller 171. In response, the microcontroller 171 controls the motor 173 to rotate and microcontroller 171 controls the LED strip light 156 to flash blue. When the user pushes the paper advance button 152, the paper advance button 152 generates and communicates a signal to microcontroller 171. In response, the microcontroller 171 controls the motor 173 to rotate and microcontroller 171 controls the LED strip light 156 to flash blue. Alternatively, the user may speak a voice command that is detected by microphone 174. The microphone 174 generates and communicates an audio signal to microcontroller 171. In response, the microcontroller 171 controls the motor 173 to rotate and microcontroller 171 controls LED strip light 156 to flash blue. When microcontroller 171 controls the motor 173 to rotate, the signal is either a signal to rotate for more revolutions or fewer revolutions, resulting in a longer or shorter length of paper dispensed. The length of paper dispensed is determined by a paper length setting 166. The microcontroller 171 determines the paper length setting 166 based on the position of the paper length switch 153.
When a user provides a user input, a signal is received by microcontroller 171. In response, microcontroller 171 controls the motor 173 to rotate. In one embodiment, motor 173 is directly attached to feed roller 158. In another embodiment, motor 173 is attached to feed roller 158 by a gear, a series of gears, a chain and sprocket assembly, a belt and pulley assembly, or other transmission means. The rotation of motor 173 causes the feed roller 158 to rotate. When the feed roller 158 rotates, paper is dispensed through the opening 162. In one embodiment, an incremental encoder is coupled to feed roller 158. The incremental encoder sends a signal to microcontroller 171 indicating how many revolutions feed roller 158 has completed. In response to the signal from the incremental encoder and using the paper length switch signal information, microcontroller 171 controls the motor 173 to stop rotating when the desired paper length has been dispensed.
When the three position switch is in the “On” position, the three position switch generates and communicates an “On” signal to microcontroller 171. In response, microcontroller 171 controls light 164 to illuminate and/or remain illuminated. When the three position switch is in the “Off” position the three position switch generates and communicates an “Off” signal to microcontroller 171. In response, microcontroller 171 controls light 164 to not illuminate. When the three position switch is in the “Motion” position, the three position switch generates and sends a “Motion” signal to microcontroller 171. When a user input is provided, it is detected by the second motion sensor 176. In response, the second motion sensor 176 generates and communicates a signal to microcontroller 171. In response, microcontroller 171 controls light 164 to illuminate. On/Off button 182 generates and sends a signal to microcontroller 171 to power on toilet paper dispenser 100 if toilet paper dispenser is powered off, or to power off toilet paper dispenser 100 if toilet paper dispenser 100 is powered on.
Signals sent from the input components to hardware interface 177 are designated in the figure. First motion sensor 159 sends a signal MS1 to hardware interface 177. Second motion sensor 176 sends a signal MS2 to hardware interface 177. Paper position sensor 160 sends a signal PPS to hardware interface 177. Paper length switch 153 sends a signal Paper Length to hardware interface 177. Microphone 174 sends a signal MIC to hardware interface 177. Three position switch 163 sends a signal TPS to hardware interface 177. Paper advance button 152 sends a signal PAB to hardware interface 177. Signals sent from hardware interface 177 to output components are also designated in the figure. Hardware interface 177 sends a signal MCTL to motor 173. Hardware interface 177 sends a signal L1CTL to motor LED strip light 156. Hardware interface 177 sends a signal L2CTL to light 164.
Microcontroller 171 receives power from supply voltage 181. Hardware interface 177 receives signals from the input components. Hardware interface 177 communicates with processor 180. Processor 180 interprets the signals received by hardware interface 177 from the input components. Processor 180 reads instructions 179 from memory 178 over data bus 182. Processor 180 applies the computer readable instructions 179 to produce output signal instructions. Processor 180 controls hardware interface 177 via data bus 182, to send the appropriate output signals to output components motor 173, LED strip light 156, or light 164.
In a second step (step 1002), the toilet paper dispenser outputs paper in response to a detected user input. Paper is output in accordance with the paper length setting detected. The user input is taken from the group consisting of: voice input, motion input, and physical input. For example, in
In a third step (step 1003), a light disposed on the toilet paper dispenser is switched on in response to user input. In the example of
In a second step (step 1202), an enclosure is formed comprising an access panel, at least two drawers, one of which is a trash bag dispenser, and a top surface made of a non-slip material. The top surface includes a plurality of ridges and valleys, at least one groove, and a raised perimeter. For example, in
In a third step (step 1203), the enclosure is attached to the paper dispenser such that the enclosure at least partially encloses the paper dispenser. For example, in
In a second step (step 1302), a determination is made whether a first motion detector detects motion, a microphone detects a voice command, or a button is pressed. If a determination is made that a first motion detector detects motion, a microphone detects a voice command, or a button is pressed, the method proceeds to step 1303. If a determination is made that a first motion detector does not detect motion, a microphone does not detect a voice command, and a button is not pressed, then the method proceeds to step 1308. For example, in
In a third step, (step 1303), a determination is made whether a paper position sensor indicates a “not empty” status. If a determination is made that a paper position sensor does indicate a “not empty” status, then the method proceeds to step 1305. If a determination is made that a paper position sensor does not indicate a “not empty” status, then the method proceeds to step 1304. For example, in
In a fourth step, an LED strip light is controlled by a microcontroller to flash red. For example, in
In a fifth step (step 1305), determination is made whether a paper length setting detected is short or long. If a determination is made that a short paper length setting is detected, the method proceeds to step 1306. If a determination is made that a long paper setting is detected, then the method proceeds to step 1307. For example, in
In a sixth step (step 1306), a controller causes a paper dispenser to dispense a short length of paper.
In a seventh step (step 1307), a controller causes a paper dispenser to dispense a long length of paper.
In an eighth step (step 1308), a determination is made whether a toilet paper dispenser is unpowered, disabled, or empty. If a determination is made that the toilet paper dispenser is unpowered, disabled, or empty, then the method ends. If a determination is made that the toilet paper dispenser is not unpowered, not disabled, and not empty, then the method proceeds to step 1302. For example, in
