| 20080209620 | Self-Closing Toilet Seat - A toilet assembly ( | 09-04-2008 |
| 20100000013 | TOILET LEAK ALERT - Embodiments of the invention include devices for reliably indicating when the water level in a toilet tank rises to the top of the overflow tube. Indicators use the presence of water in the overflow to provide for visual, olfactory and/or auditory indication of the malfunction. Features of the invention provide for a safe, inexpensive and reliable device for detecting toilet malfunction. Indicators are housed in a device that is positioned to intercept overflow water passing from the toilet tank to the toilet bowl. The presence of water in the device housing is used to release indicators into the toilet bowl water or into the air. Improvements are provided that eliminate false positive indications and prevent inadvertent damage to the toilet. | 01-07-2010 |
| 20100064426 | Toilet Seat Alarm Handle - The present invention which provides a novel means for raising and lowering the seat on a toilet bowl is composed of a housing unit which has a base portion and a handle portion, means for attaching the base portion to the bottom side of the toilet seat, a Central Processing Unit (CPU), an infrared emitter, a signal processor, an infrared receiver module, a speaker, a LED module, a power source, a ball switch, and a power detector. It is to provide a method and an apparatus in a sanitary application or especially in a public toilet, whereby the method and apparatus achieve a clean and hygienic way of raising the toilet seat, and also alert the user to lower the toilet seat after use. | 03-18-2010 |
| 20100242160 | TOILET BOWL OVERFLOW PREVENTION AND WATER CONSERVATION SYSTEM AND METHOD - A system and method for conditionally interfering with the operation of a conventional toilet tank fill valve prevents toilet overflow and conserves water. A single self-contained apparatus, located completely within the toilet tank, detects and prevents a toilet overflow and/or conserves water by conditionally interfering with or overriding the normal operation of a toilet tank fill valve to prevent a further flush. Exemplary illustrative non-limiting steps include removing the toilet tank lid to provide access to said toilet tank fill valve within the tank, manually snapping an assembly onto said fill valve protective cap, and automatically and conditionally actuating said assembly to cause the assembly to selectively interfere with or override the operation of said toilet tank fill valve. An exemplary illustrative non-limiting device comprises an attaching structure for manual attachment to said fill valve cap, and a control mechanism supported by said attaching structure. The control mechanism acts to conditionally interfere with the operation of the toilet tank fill valve assembly in response to abnormal detected toilet tank water level over time, thereby preventing a further flush. The overflow and water conservation feature can be designed into a fill valve at time of manufacture and/or added in the field by an end user. | 09-30-2010 |
| 20130232677 | FLUSH TOILET CONTROL SYSTEM AND RELATED METHOD - A control system for a flush toilet includes a water delivery device for delivering a source of flush water to a bowl. The control system includes a controller and a user interface. The controller is operative to control the toilet through a flush sequence in a first mode and a second mode. In the first mode, the controller opens the water delivery device to deliver a predetermined amount of water to the bowl. In the second mode, the controller opens the water delivery device to deliver a user adjustable amount of water to the bowl. The user interface is in communication with the controller for selecting between the first mode and the second mode. Where the toilet is a macerator toilet, the controller monitors current draw unit when the current draw satisfies a predetermined current condition. The controller may operate in a normal mode and a lockout mode. | 09-12-2013 |
| 20140053329 | CONTROL OF TOILET BOWL FILL FLOW - Various systems and methods of controlling the flow of water from a fill valve in a toilet tank to a toilet bowl of a toilet using a bowl fill valve are provided. An inlet of the bowl fill valve is coupled to a bowl fill outlet of the fill valve and the outlet of the bowl fill valve is channeled to the toilet bowl. In illustrative embodiment, a method is provided comprising the steps of determining when the toilet tank has been substantially drained of water during a flush cycle, and opening the bowl fill valve for a predefined period of time after the toilet tank has been substantially drained of water to fill the toilet bowl of the toilet with water. The predefined period of time is less than a total time of the flush cycle. | 02-27-2014 |
| 20140304903 | Odor Eliminating Apparatus for Toilets With Integral Sound Effect Generator - An odor eliminating apparatus for eliminating odorous compounds from a toilet bowl includes a housing with an extension disposed inside the bowl above the headspace of the water. A fan establishes an air flow through the housing to exhaust gases from the bowl. A filter eliminates the odorous compounds and optionally refreshes the air. The apparatus may be portable so that it can be installed onto and removed from the bowl as desired. Speakers in the housing are used to play audio clips when a person is detected. | 10-16-2014 |
| 20150059074 | OVERFLOW WARNING DEVICE DYE CLIP - The present invention relates to a device for housing a dye tablet that is capable of acting as a visual warning device to liquid overflow in liquid containers, particularly toilet cisterns. The device may be affixed to the overflow pipe by means of a clip attachment or through integration with the overflow pipe upon creation. The device contains apertures to allow liquid to enter the compartment housing the dye tablet whereby the dye particles become immersed in the liquid. The highly colourised liquid is highly noticeable as it exits the overflow pipe and thus gives warning of a system malfunction. | 03-05-2015 |
| 20150089730 | FLUSH TOILET - A flush toilet has a reservoir tank, a toilet main unit, a water supply apparatus, a water discharge apparatus, and a control device for controlling flushing of the bowl portion of the toilet main unit; wherein this control device includes a time measurement device for measuring the time after the water discharge apparatus has been driven for a predetermined time to discharge flush water, until the water level rises from a dead water level inside the reservoir tank with the water discharge apparatus in an off state to a predetermined stopped water level prior to start of flush; and the driving time of the water discharge apparatus responsive to pressure losses in the toilet main unit is adjusted by comparing the water level rise time measured by the time measurement device with the water level rise time in a standard toilet. | 04-02-2015 |
