Definitions

  • the present invention relates to an intelligent toilet and its flushing system.
  • the flushing function of conventional intelligent toilets on the European market is realized by water tanks built into the wall or in a housing element. If a user wants to use an intelligent toilet without a water tank with wall installation or in a housing element, a new arrangement of the flush water tank is required, which requires a considerable change in the sanitary space and is cumbersome, labor-intensive, time-consuming and costly. In the sanitary rooms of some users, there are sometimes restrictions with regard to the space available, etc., so that it may be impossible to install the water tank in the wall and the use of the intelligent toilet may be ruled out in this respect.
  • a pressure bag is usually used for rinsing the water tank in coordination with the siphon to carry out the rinsing.
  • the rinsing pressure is basically passed on via a spring, whereby the mains water pressure is converted into spring energy potential, which is released immediately during rinsing in order to increase the rinsing power.
  • this design relies on tap water pressure, there is no way to realize an air gap between the pressure bag and the water inlet end. There is therefore no air gap between the pressure bag and the mains water supplied from the outside, so that the requirements for preventing backflow according to EN1717 (standard for backflow prevention devices) are not met and there is no suitability for the European market.
  • the present invention provides an intelligent toilet and its flushing system which does not require a wall-mounted or in-wall water tank while meeting the anti-backflow standard.
  • the flushing system for a smart toilet includes a water inlet valve and a tank, where the water inlet valve is a water inlet valve with an air gap separation function and blocks the water inlet path when the liquid level of the tank rises to a high water level setting value and opens the water inlet path when the liquid level of the water box drops to a low water level setting. between one An air gap is provided between the water outlet path of the water inlet valve and the liquid level rising to the high water level setting. A mounting hole is disposed on top of the header box, and the water inlet valve is mounted through the mounting hole at an upper portion of the header box.
  • a water pump is provided, wherein the water outlet port of the water tank is connected to the water inlet port of the water pump through a water pipe, and the water outlet port of the water pump is connected to the flushing water passage of the ceramic body through a water pipe.
  • the smart toilet includes a ceramic body, with a basin provided in the front portion of the ceramic body, which has a flushing water passage at the rear of the upper part of the basin, and the ceramic body having a sewage drainage pipe at the rear of the lower part of the basin.
  • a flushing system for a smart toilet is also provided, which is mounted in the rear portion of the ceramic body and includes a water inlet valve and a water tank.
  • the water inlet valve has an air gap separation function, and blocks the water inlet path when the water tank liquid level rises to a high water level setting value, and opens the water inlet path when the water tank liquid level falls to a low water level setting value, with between the water outlet path There is an air gap between the water inlet valve and the liquid level that has risen to the high water level setting.
  • a mounting hole is provided on the top of the water box.
  • the water inlet valve is mounted on an upper portion of the header tank through the mounting hole, wherein a water pump is further provided, the water outlet port of the The water tank is connected to the water inlet port of the water pump through a water pipe, and the water outlet port of the water pump is connected to the flushing water passage of the ceramic body through a water pipe.
  • the intelligent toilet shown comprises a ceramic body 10, with a catch basin 12 for excretions being provided in a front section of the ceramic body, and the ceramic body having a flushing water channel 14 at the rear in the upper area of the catch basin and a waste water pipe 16 at the rear in the lower area of the catch basin.
  • a rinsing system 20 is arranged in the rear section of the ceramic body, through which the rinsing of the collecting basin 12 of the ceramic body 20 takes place.
  • the rinsing water channel 14, the collecting basin 12 and the waste water pipe 16 are conventional constructions for ceramic bodies, so that ceramic bodies according to the state of the art is referenced. The following is a description of the construction and operation of the flushing system 20.
  • the flushing system 20 comprises a water inlet valve 21 and a water tank 22, the water inlet valve 21 having an air gap separating function.
  • the water inlet valve 21 shuts off the water inlet path when the liquid level in the water tank 22 reaches a high water level setting (closure of water supply to the water tank).
  • the water inlet valve opens the water inlet path when the liquid level in the plenum box drops to a low water level setting (water supply to plenum box).
  • An air gap is provided between the water outlet path of the water inlet valve 21 and the liquid level rising up to the high water level setting. This means that after exiting the water outlet path, the water has to fall a certain distance before it hits the water of the water box.
  • the flushing system 20 further comprises a water pump 23, wherein a water outlet port 222 of the water tank is connected to a water inlet port of the water pump 23 by a water line 25, and a water outlet port of the water pump 23 is connected to the flushing water channel 14 of the ceramic body by a water line 26.
  • the water pump 23 When flushing, the water pump 23 is activated and sucks water out of the water tank 22 so that the water enters the flushing water channel 14 and finally causes flushing.
  • the water inlet valve 21 opens automatically and external water is supplied to the water tank 22.
  • the water inlet valve 21 automatically closes and the water supply to the water tank 22 is closed.
  • the water pump 23 is an impeller water pump, the position of the connection between the water pipe 26 and the flushing water channel 14 being higher than the high water level setting value.
  • the entire water path is thus continuous, even when the water pump 23 is not activated. Under normal circumstances, the liquid level of the water box 22 reaches the high water level setting. When the water pump 23 is not activated, no water flows into the flushing water channel 14. If a fault prevents the water inlet valve 21 from automatically closing, this results in a continuous supply of water to the water box, the water flowing along the water pipe 25, the water pump 23 and of the water pipe 26 into the flushing water channel 14 and thus to the collecting basin 12 .
  • the water outlet opening 222 of the water tank 22 is arranged at the bottom of the water tank and the water pump 23 is arranged outside in a lower area of the water tank 22 .
  • the position of the water pump 23 is relatively low, so that when the water is discharged, the water from the water tank 22 can directly hit the water pump 23, which enables the flushing effect to be increased.
  • the water tank 22 further includes an overflow opening 223 located higher than the high water level setting.
  • the overflow opening favors on the one hand the air discharge when water is supplied to the water tank 22.
  • excess water can flow out through the overflow opening.
  • the overflow opening 223 is higher than the position of the connection between the water pipe 26 and the flushing water channel 14. If automatic closing of the water inlet valve 21 is not possible and water continuously flows to the water tank, excess water enters the flushing water channel 14 and does not flow from the overflow opening 223.
  • a bezel 225 is preferably arranged on the upper side of the water tank 22 around the mounting opening 221 .
  • the intelligent toilet further includes a base plate 30 and a control module 40 for activating and deactivating the water pump 23, the base plate 30 being connected to a bottom surface of the interior of the rear portion of the ceramic body 10, and the water tank 22, the water pump 23 and the control module 40 are mounted on the base plate 30.
  • connection 50 the end of the water line 26 connected to the flushing water channel 14 is plugged into an inner end of a connection 50, the outer end of the connection 50 reaching through a mounting opening 18 in the ceramic body 10 and into the flushing water channel 14 protrudes, and wherein at the outer end of the terminal 50 an outwardly flared stop 52 is formed.
  • the connection 50 is surrounded by a plastic part 60 which is guided through the mounting opening 18 on the ceramic body.
  • a thread with a threaded nut 54 for the rotary connection is provided on the outside of the connection 50, with the plastic part 60 being able to be pressed from the outside and inside by tightening the threaded nut 54 in cooperation with the stop 52, so that the plastic part 60 after the expansion with the Mounting opening 18 is clamped sealingly.
  • the water pipe 26 can be inserted through the connection and the plastic part from the outside in into the mounting opening, in order to then carry out the fastening by tightening the threaded nut.
  • the plastic part is held in the assembly opening in a sealing manner, which not only makes assembly easier, but also produces a better sealing effect.
