Connections between seat elements, such as heating elements 94 , temperature sensors 96 , and other elements, is provided via electrical connections configured to pass from the seat 20 and lid 22 via hinges 26 and 28 to pod 30 .
Power to heat the heating elements 94 in seat 20 is provided by a power supply within pod 30 and connected by wires via hinges 26 and 28 .
the power supply is operably connected to a power cable 98 which is configured to operably connect to a standard wall socket to obtain power.
Electric batteries 54 may be used to provide power to a fan 34 , indicator lights 84 , and other electrical elements of an assembly 12 having features of the invention. It will be understood that variations and different embodiments may be powered by one, two, three, or other number of batteries, and that such batteries need not be D-sized, but may be A, M, C, or other sized batteries, and may include batteries of different sizes. As illustrated in FIG. 3B , the batteries 54 may be placed for ready and easy access under a removable battery cover for installation and replacement.
a fan 34 may be configured to run at any desired voltage, such as, e.g., 3V, 5V, or other voltage. In embodiments, a fan 34 engineered to run at lower voltages may be used. In one embodiment, a 5V fan is used. In such an embodiment, the nominal 3V supplied by the two D-sized batteries in series may be stepped up to approximately 5V by a voltage regulator circuit as is known in the art.
a voltage regulator circuit may be implemented on a PCB 70 , may be a separate component housed within pod 30 , or may be provided in other ways known in the art.
Such a voltage regulator circuit is also effective to provide a relatively steady voltage supply to the fan even as the supply voltage from the batteries varies from approximately 3.6V when the batteries are fresh to 1.2V when the batteries are considered “dead”.
the fan will be enabled to perform relatively consistently throughout the life of the battery.
Such consistent power usage is advantageous for providing more consistent power to the fan, so that the operation of the fan is more consistent than it would be in the absence of a voltage regulator circuit, and is advantageous in that a constant rate of power usage is believed to improve the overall operational life of the batteries.
a fan 34 may be powered by batteries 54 without a voltage regulator.
4 D-sized batteries in series may be used to run a 5V fan.
the total voltage is about 7V, providing power that causes the fan to run faster than it runs at lower voltages.
the initial rate of decline in battery power is thus faster than the later rate of battery power decline, as the output voltage declines, and the fan turns more slowly.
the fan slows down, reducing the air-flow performance.
a 5 V fan is expected to stop spinning at a supplied voltage of around 3V, at which time the batteries need to be replaced.
a direct current (DC) power source including a wall-socket plug, wire, alternating current (AC)-to-DC converter (of any sort known in the art) may be used to provide electrical power.
batteries, AC and DC power sources may each be provided for use as most convenient or as needed.
the battery power may be bypassed when a DC jack connected to an AC-to-DC converter is plugged in, or DC power is provided in any other way, so that no current is drawn form the batteries when power is obtained from a DC power source.
rechargeable batteries may be provided in an embodiment configured to recharge the batteries when a DC jack is plugged in and so provides power.
embodiments of the devices, assemblies, and systems having features of the invention include heating elements in the toilet seat.
AC power from a wall-socket may be used to provide power to the heating and control elements to provide for heated toilet seat.
Deodorization is achieved by drawing air from the toilet bowl and passing the air through, over, or around a deodorizing element that removes, alters, and/or masks the odor from odor-causing molecules.
Odors that may be found offensive and which may be removed, altered, or masked include amine odors, including ammonia, ammonia sulfide, diethylamine, and triethylamine; mercaptans such as ethyl mercaptan and methyl mercaptan; sulfur compounds, comprising methylsulfide, dimethyl sulfide, and hydrogen sulfide; aldehydes, such as formaldehyde and acetaldehyde; phenols, such as phenol and cresol; unsaturated compounds such as such as styrene; and others.
An effective deodorizing element is one that can remove, alter, or mask the majority of odor causing molecules in the air that passed by or through it.
a master power switch on the pod is provided to enable or to disable the deodorizing function.
Deodorizing elements may include a filter, a catalyst, an energy source, a neutralizing compound, or other element effective to deodorize air passing by or through the deodorizing element.
a filter may include a catalyst, a neutralizing compound, or other element effective to deodorize air, and may include an energy source.
Filters are configured to allow air to pass, and to condition air as it passes through or by the filter. Filters may be configured to trap particles and odor-causing chemicals, and may include natural materials, gauze, mesh, glass, plastic or composite wool material, porous materials, or other materials and elements effective to remove particles and odors from the air.
the pod includes a portion that overhangs the toilet bowl and has an inlet opening that faces downwards into the bowl. Such a portion is illustrated in FIGS. 3 and 4 as discussed above.
a vent is provided on the pod at a position opposite to the inlet opening.
a 50 mm ⁇ 50 mm ⁇ 10 mm box-fan disposed inside the pod in fluid contact with the inlet opening is used to generate air flow. It will be understood that other sizes and designs of fans are suitable as well. Air enters through the inlet, goes through the fan, then through the filter, and finally out a vent at the rear of the pod.
the filter is a deodorizing filter effective to reduce the amount of odor-causing material in the air flowing out of the vent as compared to the amount of odor-causing material in the air flowing into the inlet.
the filter is located approximately 1 ⁇ 2 inch away from the fan (rather than right up against the fan) to allow less restricted air-flow.
the filter is disposed at a position near, but not in contact with, the fan to provide improved performance by providing less restricted air-flow than would occur were the filter placed directly in contact with the fan.
more than one filter may be used, including filters of more than one type or of more than one means of deodorization.
a deodorizing filter may include activated charcoal, as a powder, as granules, or in other forms.
Activated charcoal may be present in or on a mesh, as granules packed loosely together so as to allow airflow between and around granules, as coatings on a mesh, grating, network, or other surface configured to allow contact between the activated charcoal and passing air, or may be present in other configurations.
activated carbon filters include extrusion-molded activated carbon elements, typically utilizing activated charcoal powder.
activated carbon filters include compression-molded activated carbon elements, typically utilizing activated charcoal granules. Such activated carbon elements typically also include binders.
Activated carbon filters, and other filters are typically configured to have many holes or passages through which air may flow. Such air flow is typically impelled by a fan.
a filter may include a catalyst, energy source, neutralizing element, or other deodorizing element.
Catalysts include low temperature catalysts that deodorize air by absorption and by catalyzing decomposition of odor-causing compounds (e.g., by oxidation of such compounds).
Catalysts may include metals and metal oxides, such as manganese compounds (e.g., manganese oxides and manganese acids), titanium compounds (such as titanium oxides), or other compounds or elements suitable for deodorizing.
Energy sources useful for deodorizing include corona discharge elements and plasma discharge elements effective to deodorize and/or sterilize air.
Ultraviolet light is also useful for reducing odors, by effecting the decomposition of odor substances and by killing or injuring microbes.
-Ultraviolet light may be used in conjunction with a catalyst (e.g., a titanium dioxide catalyst) to catalyze the decomposition of odor-causing compounds.
a catalyst e.g., a titanium dioxide catalyst
Neutralizing compounds such as bicarbonate of soda, may absorb or neutralize odors in air. Filters are effective to deodorize air by trapping and removing odor-causing compounds from passing air.
a filter is a consumable component that has a finite usable life, and requires replacement on occasion.
the pod is configured to allow a user to easily replace the filter when needed.
a filter is accessible under the same cover that is used for accessing the batteries.
a switch or sensor that senses when the filter is properly in place or not. For example, proper placement of the filter may depress a detent that closes a circuit configured to provide an indication of proper placement (e.g., when properly placed, a circuit is closed to allow current flow to illuminate an indicator light, or, proper placement opens a circuit to shut off an indicator light that indicates improper placement of the filter).
a sensor may be configured to allow the micro-controller to track how long a filter has been in place and indicate to the user (via an LED or other means) when the filter should be replaced.
the fan is deactivated when the filter is not in place. This may provide an advantage in that running the fan without a filter is expected to exacerbate odor issues associated with toilet use.
a fan suitable for use in the systems, assemblies and devices having features of the invention is capable of providing airflow effective to withdraw air from a toilet bowl and to pass air to and through a filter.
a suitable fan may provide airflow of between about 0.05 cubic meters per minute (m 3 /min) and about 0.5 m 3 /min, or between about 0.1 m 3 /min and about 0.3 m 3 /min, or between about 0.15 m 3 /min and about 0.2 m 3 /min.
a suitable fan may provide airflow of about 0.15 m 3 /min, or about 0.18 m 3 /min, or about 0.19 m 3 /min.
a fan may be configured to produce a minimum of noise while providing sufficient airflow.
Airflow of less than about 0.3 m 3 /min, or airflow of less than about 0.2 m 3 /min, provides sufficient airflow while producing acceptable amounts of noise.
Such fans may be powered by 12 V or by 5 V direct current (DC) power, which may be provided by batteries, by alternating current (AC) power supplies which provide DC power, or any suitable means.
DC direct current
AC alternating current
a vent cover such as vent cover 38 having downwardly pitched vanes 39 illustrated in FIGS. 2 , 3 A, 3 B and 3 D, is an example of a removable set of louvers configured to fit into the air outlet 36 at the rear of the pod 30 .
louvers are configured to help shed dripping water or other liquids and debris towards the outside of the pod.
the louvers may be molded as a single piece that can slide vertically in and out of slots on either side of the vent, or may be made of separate pieces configured to fit together to form a louver effective to direct airflow and help shed water and other liquids and debris.
pod lid 50 which serves as a battery/filter cover must be opened or removed to do so. It will be understood that alternative embodiments may be configured so that a louver, such as a vent cover 38 or other element serving a similar purpose, may be configured for removal or replacement without requiring the removal or displacement of a pod lid 50 .
such a louver part may be molded with various impregnated fragrances or aromas, or have scented coatings which provide fragrances or aromas.
fragrances or aromas passively dissipate into the air at all times.
fragrances or aromas are dissipated at increased rates and amounts when the fan blows air past or through a louver part, so that the effects of these fragrances or aromas are increased when the fan is on.
impregnated or coated louvers provide the advantage that a variety of fragrances and aromas may be easily swapped out by the user at will, and may be easily replaced for fresh louvers as needed.
louvers The useful life of such impregnated or coated louvers is limited however, as only a finite amount of fragrance or aroma may be impregnated in or coated on such a louver part.
such louvers may be replaced, e.g., at regular intervals, or as desired by a user, as the amount of fragrance or aroma declines over time.
the fragrance or aroma component for use with a replaceable louver or with a replaceable cartridge may consist of a coating, an impregnated material, a cartridge, a louver, or a stick, block, or sheet that would passively give off molecules of a desired odor or scent (by evaporation or sublimation). Placement in the airflow would increase the release or emission of the fragrance or aroma while the fan was on. It is advantageous to place the fragrance or aroma component after the filter in the air flow in order to minimize the amount of the fragrance or aroma that is absorbed or altered by the filter.
fragrances derived from or resembling natural smells such as flower fragrances, fruit fragrances, perfumes, and other fragrances pleasant to smell, or which may evoke pleasant associations or sensations in a person sensing them, are all suitable.
Particular examples include, but are not limited to, lemon, acacia, pine, peach, hazelnut, and other fragrances.
a fragrance may also have effects other than its mere ability to be sensed by a person's sense of smell, and so may also serve as an aromatherapy aroma.
Aromatherapy aromas suitable for use in the systems, assemblies and devices disclosed herein may further include aloe vera, ambergris, castor, chamomile, cinnamon, cypress, eucalyptus, fennel, geranium, honey, jasmine, lavender, orange, peppermint, sage, rose, rosemary, vanilla, and other aromas.
An aroma suitable for aromatherapy may, but need not, provide a detectable fragrance. However, an aroma suitable for aromatherapy may also have a fragrance that may be sensed by a person, and is therefore also suitable for use as a fragrance.
Aromas providing pleasant fragrances and also believed to provide physiological, emotional, or temperamental effects include chamomile, eucalyptus, jasmine, peppermint, rosemary, and other aromas.
a component providing fragrance or aroma may be arranged to be accessible without removing the pod lid 50 for easier swapping.
a stick, block, or sheet may be placed in a slot, channel, or other receptacle in the pod 30 , pod lid 50 , or vent cover 38 .
a “valve” may be placed between the deodorizer 46 and dispenser 48 (or other fragrance or aroma component as described above) to reduce the amount of fragrance or aroma that is passively absorbed or altered by the filter when the fan is not in use, thus extending the usable life and effectiveness of the deodorizer 46 and dispenser 48 (and other fragrance or aroma components where present).
a flap may be provided that at least partially covers the outwardly exposed surface of the deodorizer 46 adjacent the dispenser 48 , reducing the amount of passively scented air that enters the deodorizer 46 (from the direction opposite to the flow induced by action of the fan) when the fan is not in use. The flap is blown out of the way when the fan is on, allowing proper air flow and providing dispersion of fragrances or aromas into the air outside a toilet.
a valve (which may be a flap, or may be any other valve or flow-controlling device) may be mechanically controlled by, for example, a solenoid, a magnet, a mechanical coupling, a lever, a gear, a rack and pinion, or other mechanical, electromechanical, magnetic, hydraulic, piezoelectric, or other control mechanism.
aroma or fragrances may be delivered or emitted via an active mechanism that uses pressure, heat, or other dispersion methods to release the scent at specified times.
These aromas or fragrances may be released at preset or programmed times chosen by the user or as initially set at the time of manufacture, including preset or programmed times that are at regular intervals, or at that are at certain time points during the deodorization operational modes.
a mechanical switch may be built into the underside of the toilet seat, and that touches the top surface of the toilet bowl when the seat is in the down position.
the wiring to the switch passes through the seat hinge and into the pod. In the nominal position, the switch is open.
a downward force e.g., provided by the weight of a person sitting on the on the seat
a capacitative sensor or body-conduction sensor in the seat, pod, or lid may be provided that senses the proximity of a user.
a sensor may be an infrared or other electromagnetic radiation sensor, which may include a source of infrared or other radiation, and be configured to detect reflection of such radiation from a user seated on a toilet seat, or to sense blockade of radiation by the presence of a user across a path otherwise taken by such radiation. Where the sensor is in the seat, or otherwise calibrated to distinguish the location of the person, such a sensor provides the benefit of distinguishing between a person sitting directly on the seat vs. a person sitting on a closed lid or some other object resting on the seat.
an electronic, pneumatic or hydraulic sensor in the seat may be provided that senses the presence of a user seated upon the seat by movement of fluid or gas within the sensor caused by pressure on the seat (and thus pressure on, or flexion of, at least a portion of the sensor).
Such an electronic sensor may be, e.g., a strain gauge, or a piezoelectric device.
a pneumatic or hydraulic sensor may include a chamber filled with a flowable fluid or gas which moves in response to pressure or flexion of at least a portion of the sensor effective to sense the presence of a user.
activation may be disabled with a switch or sensor that senses when the lid is closed.
a switch or sensor that senses when the lid is closed.
application of downward force on the sensor may be prevented and so prevent a downward force on the lid from mechanically translating to the seat and seat switch.
a delay e.g., a 1 or 2 second delay
the switch opens, or the sensor is de-activated, after a very short duration (e.g., 2 seconds) the fan will not come on at all.
the switch opens, or the sensor is de-activated, after a very short period (e.g., 2 seconds) and before a short period (e.g., 20 seconds) the fan will continue for very short period (e.g., 5 seconds) before stopping. If the switch is closed again, or the sensor is re-activated, before the fan stops, the fan will continue as if the switch was not opened or the switch not re-activated. (And thus the timing is still measured from the initial time.)
the fan will continue for an “overrun” period (e.g., 60 seconds) before stopping. If the switch is closed again, or the sensor is re-activated, before this overrun period is complete, the fan will continue as if the switch was not opened (or sensor de-activated) and the “overrun” period will be reset for the next time the switch is opened (or sensor de-activated).
a short period e.g. 20 seconds
an “overrun” period e.g. 60 seconds
the fan will automatically stop.
the system will be reset as soon as the switch is opened again, or sensor is de-activated again. (This is intended to prevent undue battery drain in the event the user places something on the seat or lid that may accidentally activate the fan.)
an LED on the top of the “pod” will be lit to indicate that deodorization is active whenever the fan is on.
an LED When the battery supply voltage drops to a certain level (TBD) an LED will blink to prompt the user to replace the batteries.
TBD battery supply voltage drops to a certain level
the same LED used to indicate the deodorization is active will begin to blink (e.g., 0.5 sec on, 0.5 sec off). It will only be on and blinking when the fan is running. Alternatively, the LED may continue to blink even when the fan is off to make sure the user sees it.
this embodiment has the disadvantage that it will continue to drain the battery further.
the LED may be a multi-color LED so that it can be one color for normal deodorization mode, and another color (blinking or not) for low-battery indication.
a second LED may be used, any color, blinking or not blinking.
