Toilet Seat Cleaner

Abstract

A toilet seat cleaner built into a hollow toilet interior and left and right hollow wing portions. One wing contains a cleaning solution and venturi valve. The other wing contains a forced air assembly. The perimeter of the top of the seat includes a raised portion having water and air outlet apertures. When the toilet is flushed, pressurized water to flows into the venturi valve and into an enclosed channel within the seat causing cleaning solution to be drawn into the stream of water and forced out of the water outlet apertures. When cleaning is complete, the forced air assembly forces into the channel and out of the air outlet apertures. The cleaning action is started when a flow sensor sees that the toilet has been flushed. The toilet seat is hinged and can be lifted in the same way as a standard toilet seat.

DETAILED DESCRIPTION OF THE DRAWINGS AND PREFERRED EMBODIMENTS

[0035] Detailed descriptions of the preferred embodiment are provided herein. It is to be understood, however, that the present invention may be embodied in various forms. Therefore, specific details disclosed herein are not to be interpreted as limiting, but rather as a basis for the claims and as a representative basis for teaching one skilled in the art to employ the present invention in virtually any appropriately detailed system, structure or manner.

[0036] Referring now to FIG. 1 we see a front perspective view of the toilet seat assembly 100 mounted on a standard toilet bowl 22. A standard lid 6 is hinged 8 in the standard fashion so that it can close over seat portion 2. The seat 2 has integral left and right hollow wings 12, 10. The left wing 12 houses a cleaning solution bottle 34 and a venturi valve 36 as will be shown in the section view in FIG. 5. The right-side wing 10 houses a forced air assembly such as a motorized fan or an air compressor not shown. It also may house a heating element that warms the stream of air as it makes its way onto the surface of seat 2 during the drying process. The standard water bib 14 and bib hose 15 lead to a Y junction box 16 which houses a solenoid valve that can allow water to enter hose 20. The sheath around hose 20 also can contain a flexible heating element that can warm the incoming water as it is used for liquid cleaning purposes. If needed, a water pump, not shown, can be added to hose 20 to further increase the pressure of water and associated cleaning solution that will be used in the seat cleaning process. Standard hose 18 leads to the toilet water reservoir 24. Water from hose 18 is used in the standard way to refill reservoir 24 after the toilet is flushed by a user. A flow control sensor, not shown, is also installed within Y junction housing 16 and senses when the water in hose 18 is flowing and sends a signal to a microprocessor located in hollow wing 12 which starts the cleaning and drying process, which will be discussed below. A second optional way to start the cleaning process uses pressure switch 30, shown in FIG. 3. When a person sits on seat 2, the switch 30 is pressed down. The act of pressing down switch 30 causes the heater 46, shown in FIG. 9 to warm up thereby providing a comfortable experience for the user. When the person rises from seat 2, the switch 30 is deactivated thereby sending a signal to a microprocessor located within wing 12 to start the cleaning process. A third optional way to start the cleaning process is for a person to press switch button 52. This option can be used when the person is not actually using the toilet but still wants to clean the seat. A raised perimeter ring 4 on the outer edge of the seat 2 includes a plurality of outlet apertures that can let cleaning solution or forced air out onto the surface of seat 2 as will be discussed below. A standard proximity sensor mounted to the underside panel 32 can detect when the seat 2 is in the down position or the up position based on its closeness to the top surface of bowl 22. That information is sent to the microprocessor. The microprocessor will only let the cleaning process take place when the seat is in the down position.

[0037] FIG. 2 is a perspective view of the toilet seat assembly 100 showing the right side where forced air wing 10 is in view. The hollow housing 10 encloses a forced air assembly. A power cord 26 plugs into a standard 110 VAC outlet 28 to power the electrical components of the invention. Alternately, a removable and replaceable rechargeable battery 38 as shown in its removed state in FIG. 6 can power the electronic components of the invention 100.

[0038] FIG. 3 is a left side perspective view of the invention with the seat portion lifted via hinge members 8 exposing the underside panel 32 of the seat 2 which includes pressure switch 30. The seat 2 in the up position allows the toilet to be used by men to urinate into the bowl 22 in the standard way.

[0039] FIG. 4 is a partial perspective view of the invention 100 showing the cleaning solution bottle 34 removed from the cleaning solution wing 12. The bottle's tip includes a check valve that can be overcome when the tip is inserted into venturi valve 36 as shown in the section view in FIG. 5. When pressurized water flows through valve 36 the water flow draws a portion of cleaning solution 35 into the stream. A photo sensor, not shown, is located near the lower portion of the cleaning solution container 34. When the cleaning solution 35 reaches the level of the photo sensor, a signal is sent to the microprocessor to initiate an intermittent warning beep to let the user know that it is time to add more cleaning solution.

[0040] FIG. 6 is a partial perspective view of the invention 100 showing the removal of optional battery power supply 38.

[0041] FIG. 7 is a partial perspective view of the invention 100 showing the apertures 40 that let liquid or air out for cleaning and drying the seat 4. The apertures 40 are inwardly pointing so that the liquid falls into the toilet bowl 22 after cleaning the seat. The raised perimeter portion 4 is hollow underneath creating a channel for the liquid or air to pass through as shown in FIG. 9. FIG. 9 is a view of the underside of seat 2 with the bottom panel 32 removed exposing channel 44. Cleaning solution enters the channel 44 at location 44B. Forced air enters the channel 44 at location 44A. The underside panel 32 of the seat 2 completes the channel 44 enclosure thereby creating a liquid and air retaining tube. The view in FIG. 9 also shows an optional heating element 46 that can warm the seat 2 during use.

[0042] FIG. 8 shows a perspective view of the underside 32 panel of the seat 2. The underside panel 32 includes a plurality of LEDs 42 on the outer perimeter of panel 32 and a plurality of LEDs 48 on the inner perimeter of seat 2. The outer LEDs 42 cause a glowing effect between the seat panel 32 and the toilet bowl 22 when the seat 2 is in the down position. The inner perimeter LEDs 48 are aimed into the water in the toilet bowl 22 making it easier to see the water during darkened conditions. A photo sensor, not shown, detects the ambient light conditions in the area around the toilet and sends a signal to the microprocessor to turn on the LEDs 42, 44.

[0043] It should be noted that the above invention can be built into a complete toilet rather than a toilet seat. The solution containing area and forced air area can be located in the rear of the seat, between the seat and the toilet reservoir. Although the power cord is shown exiting the right side forced air housing, it can also be made to exit the left side cleaner solution housing. Excess cord may be stored within either the forced air housing or the cleaning solution housing, or the space between the two housings. The above described invention can be used in bathrooms located in a home or used in commercial locations such as restaurants or offices.

[0044] While the invention has been described in connection with a preferred embodiment, it is not intended to limit the scope of the invention to the particular form set forth, but on the contrary, it is intended to cover such alternatives, modifications, and equivalents as may be included within the spirit and scope of the invention as defined by the appended claims.
