Definitions

  • the present invention relates to a water closet with a cistern and an automatic cleaning device, which is functionally coupled to the inlet of the cistern, for cleaning and disinfecting the rotatably mounted and also automatically rotating in the circumferential direction during the inlet and cleaning phase by at least 360 °, the cleaning device completely passing toilet seat, wherein the cleaning device extends over a segment of the ring-shaped seat and has organs for supplying water and / or disinfectant liquid primarily affecting the top of the toilet seat and for drying.
  • a segment of the seat is enclosed by a transport and cleaning body.
  • this body there are nozzles for water and disinfection cleaning including a scraper to dry the seat surface.
  • the said body also includes the seat in the rest position.
  • the rotation of the seat necessary for cleaning is achieved by means of a water drive wheel, the feed of the rinsing water being used for driving.
  • the seat is mounted between at least one support roller and at least one drive roller arranged under the seat.
  • This device is functional, but has the disadvantage that the transport and cleaning body encloses the rear segment of the toilet seat even in the idle state, which disrupts the use of the water closet and makes it appear unsanitary.
  • the present invention has for its object to provide a device for the automatic cleaning of a seat of a water closet, which does not have the disadvantages of the known and outside the cleaning phase, i.e. the rest position, the entire surface of the seat free of cleaning and driving parts.
  • a water closet of the type mentioned at the outset in that the aforementioned organs are integrated in a displaceable, common sliding housing which is fixedly connected to a preferably rear part facing away from the user (see FIG. 16) of the water closet and outside the cleaning phase occupies a position behind or outside the toilet seat, and that adjustment elements are also provided to automatically slide the sliding housing out of this rest position at the beginning of the cleaning phase again in conjunction with the cistern inlet onto the top of the toilet seat.
  • the main advantage of this new device is that the entire seat surface is free in the resting and use phase, and that the sliding housing is only placed in the cleaning phase on a preferably rear, user-distant segment of the seat and that automatically subsequent cleaning and drying measures are also carried out automatically, including the return of the sliding housing to its rest position.
  • the automatic function of the cleaning device and its organs, including their displacement into the cleaning phase, is preferably carried out on the basis of an electrical control with corresponding actuators.
  • the electrical energy required for this is preferably by means of the inlet water flowing under pressure into the cistern after the flushing, i.e. generated during the cleaning phase, in which the inlet water acts on a turbine, which in turn drives a small power generator.
  • the seat is only rotated through 360 ° , spraying or wetting it and drying it at the same time with at least one scraper.
  • the seat twice through 360 ° , spraying or wetting with the liquids during the first rotation and drying during the second rotation. This is particularly useful in most countries where the seat has an oval shape. In the USA, for example, more and more people are beginning to use circular seats.
  • the rotation need not be 360 ° , because the rest position can be arbitrary. For example, a rotation of 400 ° could be provided, the most stressed point on the surface of the seat then moving in the circumferential direction of the seat for several rotations.
  • spraying and wetting with the liquids could be carried out during the rotation through 360 ° , while only drying would be in operation during the remaining 40 ° . This could prevent the zero point under the sliding housing from getting wetter than the other parts.
  • An air stream can also be used for drying.
  • At least one valve for spraying the water and / or the disinfectant liquid is opened by means of at least one movable part and is kept open during the front working position during the forward movement of the sliding housing.
  • the sliding housing and the seat are driven by electric motors.
  • This solution is very economical, because in this case no complicated mechanical gears are necessary, the necessary electric motors being manufactured in series and thus also making this solution economical.
  • the electrical energy for driving the electric motors and control electronics is obtained by means of a turbine which is driven with the water flowing into the rinsing water reservoir after opening a valve of a float body and that a turbine is mechanically driven by this turbine.
  • This training has several advantages. You do not need any external energy, for example from the power grid, although - as already mentioned - it is of course possible, especially with new installations and if a low voltage source is already available for other reasons, use this source directly without the turbine and power generator mentioned. Another advantage can be seen in the fact that the function of the turbine and thus of the power generator is only linked to the refilling of the rinsing water reservoir and that the kinetic rinsing energy of the rinsing water is thus not reduced.
  • valves for the line of the cleaning water and / or the disinfectant liquid are also controlled by the control electronics.
  • This variant can replace the solution described earlier, in which the valves are mechanically controlled by at least one moving part: it is up to the designer which of the solutions described is used.
  • control electronics are informed of the position of the seat by means of a contact arrangement.
  • Two pairs of contacts are expediently used, which signal the position of the seat. They inform the electronics whether the seat is loaded or whether it is already freely lifted and not loaded.
  • Most toilet seats are not circular, but at least the inside diameter is elliptical. With this type of seat, it is also important whether the seat is in the so-called zero position, i.e. The narrow parts of the seat are located in the front and rear. This increases the security of the procedure and prevents possible injury to the user, especially a child.
  • the seat is wiped off with at least one radially extending wiper and at least one wiper extending in the circumferential direction of the seat during the rotational movement of the seat and the backward movement of the slide housing. It has been shown that in relation to the fact that only a small amount is sufficient to moisten the seat surface and that a quick-drying liquid can be used as the disinfectant liquid, a radially extending scraper is sufficient to dry the surface of the seat sufficiently.
  • the scraper extending in the circumferential direction of the seat is fastened on a tiltable lever which is held in the upper inactive position by a solenoid and which is lowered onto the seat when the slide housing moves back and wipes it off. It is thus achieved that the scraper is only lowered shortly before the sliding housing moves back and that it then dries the remaining moisture strips on the surface of the seat well with sufficient pressure.
  • the surface of the seat is dried with an air stream.
  • This variant is particularly advantageous in connection with existing hygiene facilities on toilets that already have an air flow or a hot air flow source.
  • the device for carrying out the method is expediently designed such that the sliding housing is slidably mounted on guide rails and is pulled outwards with a helical spring. This construction enables the device to be used without interference even with elliptical shapes of the seat.
  • the sliding housing is expediently provided with support rollers. These support rollers have vertical axes and support the inner profile of the seat with their peripheral surfaces.
  • the slide housing thus also follows this profile, the slide housing being pulled outwards with the helical spring, as mentioned above, and thus ensuring the contact of the support rollers with the seat.
  • the source of the disinfectant liquid is designed as a container in which the disinfectant liquid is under gas pressure. You can of course use one of the known environmentally friendly propellant gases or the closure of the container can be designed as a known pump valve, which ensures sufficient air pressure above the disinfectant liquid during cleaning in a manner known per se. There is also the possibility that the fluid outflow will reach the points to be disinfected due to the gravitational force due to the difference in level.
  • the seat In order to facilitate the rotation of the seat during cleaning, the seat is placed on steel balls, which are rotatably inserted in a compressible elastic ring. In this simple way, when the seat is unloaded, it can be rotated in the circumferential direction with a small force, the seat resting on hard parts in the loaded state, which prevent any rotation due to the frictional force.
  • a wetting element is arranged on the sliding housing, which contains a sponge insert, which is provided with a fabric insert, and is intended for wetting the seat with the disinfectant liquid.
  • This solution is particularly suitable for fast-drying disinfectant liquids, the desired surface of the seat being well wetted with the disinfectant liquid.
  • the electrical circuit is expediently designed such that the electric motor for driving the sliding housing is connected to the energy source via a forward logic, a reverse logic and two power levels. Both forward and backward movements are thus controlled as planned.
  • the power levels contain sub-levels for full power and sub-levels for reduced power of the electric motor.
  • the motor is supplied with the correct, i.e. not too large and not too small, energy, so that on the one hand the correct and error-free movement of the slide housing is ensured and on the other hand the movement is controlled only with the minimum force, so as not to cause any injuries, especially when Children.
  • the at least one electric motor for driving the seat is connected to the energy source via control logic and an amplifier stage. This measure also only ensures the necessary energy supply.
  • the electrical circuit contains two memories which register the position of the safety switches and the information of the timing element.
  • the safety switches signal the position of the seat and prevent any incorrect operation of the cleaning arrangement.
  • an end position monitoring circuit contains three functional units, of which the first unit with the forward logic, the first memory and with a timing element, the second unit with the reverse logic, and finally the third unit with the control logic for the electric motors rotating the seat and on the other hand are connected to a solenoid via a timing element and an amplifier stage.
  • the three functional units expediently monitor the three different movements, i.e. the forward and backward movement of the slide housing and the rotating movement of the seat.
