Definitions

  • the present invention relates to toilet seat cleaning systems and, more particularly, to a novel electronically controlled device for toilet seat cleaning having a built-in toilet seat and means for automatically washing and drying the same.
  • toilet bowls are mostly considered a capital expense and therefore are not replaced frequently, it is another object of the present invention to provide an automated toilet seat cleaning system which is compatible with existing toilet bowls and which can be mounted without a change of their shape or plumbing.
  • FIG. 1 is a perspective view of the system's housing and toilet seat
  • FIG. 2 is the top view of the system's housing, showing the upper door frame and its position when the door is closed;
  • FIG. 3 is a perspective view of the toilet seat, its driving electric motor, and its support frame;
  • FIG. 4 is the right side view of the system housing mounted on a toilet bowl, showing its parts in.a washing position;
  • FIG. 5 is the front view of the system's housing, showing the position of the washing brushes
  • FIG. 6 is a block diagram of the system as disclosed by this invention.
  • FIG. l illustrates one embodiment of the present invention.
  • a system housing 1 its sliding door 2, and a toilet seat 3 in the down position.
  • the sliding door 2 as shown in FIGS. 1 and 2 is preferably made of hard rubber and is driven by electric motor 4, as shown in FIGS. 2, 4, and 5, along the frame on the top and bottom of the housing wall over the small rotating cylinders 19 located in the bottom frame as shown in FIGS. 4 and 5.
  • the door 2 is designed, when closed, to prevent any water leakage outside of the system's housing 1. All of the tasks to be performed are electronically guided by the system's control box 8, shown in FIG. 4, and all electrical components are properly isolated and insulated so that any contact of electricity and water is impossible so as to avoid any hazardous situations.
  • the system may be equipped with photo sensor(s) (not shown) which could be located anywhere inside the toilet stall and connected to the control box 8. Such photo sensor(s) may be used to signal the Central Processing Unit (CPU) 21 when to start the washing and drying process. Such starting instructions could also be signalled by some other means, such as the toilet flushing lever or the lock to the toilet stall door.
  • photo sensor(s) not shown
  • CPU Central Processing Unit
  • Such starting instructions would signal to CPU 21 that the washing and drying process can occur.
  • the CPU 21 then activates the electric motor 4, shown in FIGS. 2, 4 and 5, thereby driving the sliding door 2 clockwise into the housing's rear wall until it reaches the spring 5, shown in FIG. 2, which, when pressed, activates an electromagnetic sensor which further signals to the CPU 21 that the door 2 is properly opened.
  • the spring 51 mentioned later in this description is located on the opposite side from spring 5 and acts according to the same principle when door 2 is closed.
  • Electric motor 4 now drives the door 2 back to a closed position, thereby closing the front opening.
  • the door 2 stops when its right edge presses the spring 51 shown in FIG. 2.
  • the system is equipped with water heating device 17 which starts heating the water in the spiral part of the water pipe 16 at the very beginning of the process, i.e. simultaneously with the first mentioned activity of the electric motor 4, and continues the heating during the washing procedure.
  • the system's electro-magnetic valve 15, FIG. 4 is activated thereby enabling water from pipe 16 and disinfecting agent from container 13, which can be refilled through its opening 18 as shown in FIG. 4, to flow forward into the spray nozzles 14, FIGS. ' 4 and 5.
  • the system's water pipe 16 is connected to an external pressured water pipe. If needed, however, a small actuator can be installed to provide the necessary water pressure.
  • a certain limited amount of disinfecting agent is released from its container and is mixed with the water during the washing procedure.
  • a high speed electric motor 9 is activated thereby rotating washing brushes 10, FIGS. 4 and 5.
  • the brushes 10 rotate and wash the toilet seat 3 with a mixture of water and disinfecting agent sprayed through the plurality of spray nozzles 14.
  • the electric motor 9 stops causing all of the brushes 10 to stop, and the electromagnetic valve simultaneously closes thereby ending the flow of water and disinfecting agent.
  • the water heating device 17 is switched off and the electric motor 6 moves the toilet seat 3 towards the housing's sliding wall far enough so that it loses contact with the brushes, as shown in FIG. 4 where this position of the toilet seat 3 is shown in dotted lines.
  • the water used is released into the toilet bowl 20 through an opening (not shown) in the bottom of the system's housing 1 thereby also disinfecting the toilet bowl 20.
  • the used water then remains inside the bowl until the next flushing thereby having a further positive sanitary effect.
  • hot air fan 11, FIG. -4 is activated and blows hot air toward the toilet seat 3 through the plurality of nozzles 12 which are located in between the brushes 10.
  • the nozzles 12 are located in line with the brushes' axles in order to obtain the best possible drying effect without being damaged by the raised toilet seat 3.
  • the fan's 11 activity is stopped and the electric motor 4 is activated.
  • the motor 4 now drives the door 2 clockwise as previously described, leaving a front opening through which the toilet seat 3 is lowered back to its starting position on the toilet bowl 20 by the electric motor 6.
  • the electric motor 4 drives the door 2 counterclockwise to its closed position until its right edge presses against spring 51.
