Definitions

  • the 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 a smart toilet without a built-in wall tank or in a housing element, a new arrangement of the flush tank is required, which means a significant 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 water tank flushing in coordination with the siphon to carry out the flushing.
  • 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 cistern while meeting the anti-backflow standard.
  • the flushing system for a smart toilet includes an electromagnetic valve, a tank, a water pump, and a float level switch, the float level switch protrudes into the tank and controls the closing of the electromagnetic valve when the liquid level of the tank rises to a high water level.
  • the float liquid level switch controls the opening of the electromagnetic valve when the liquid level of the water tank decreases to a low water level set value, with a water outlet port of the electromagnetic valve is connected through a water pipe to a water inlet port of the water tank, wherein a water outlet port of the water tank is connected through a water pipe to a water inlet port of the water pump, a water outlet port of the water pump is connected through a water pipe to a flushing water channel of the ceramic body, the water inlet port of the water tank at the top water box is arranged and the water outlet opening of the water box is arranged at the bottom of the water box, and there is an air gap between the water inlet opening of the water box and the liquid level rising to the high water level setting.
  • the smart toilet includes a ceramic body, with a pan provided in the front portion of the ceramic body, the ceramic body having a flushing water channel at the rear of the upper portion of the pan, and the ceramic body having a drain pipe at the rear of the lower portion of the pan.
  • a flushing system which is mounted in the rear portion of the ceramic body and includes an electromagnetic valve, a water tank, a water pump, and a float liquid level switch, the float liquid level switch protruding into the water tank and controlling the closing of the electromagnetic valve when the liquid level of the tank reaches a high water level setting, the float liquid level switch controlling the opening of the electromagnetic valve when the liquid level of the tank falls to a low water level setting, a water outlet port of the electromagnetic valve being connected to a water inlet port of the tank by a water pipe , wherein a water outlet opening of the water tank is connected by a water pipe to a water inlet opening of the water pump, wherein a Water outlet port of the water pump is connected to a flushing water passage of the ceramic body through a water pipe, with the water inlet port of the tank at the top of the tank and the water outlet port of the tank at the bottom of the tank, and between the water inlet port of the tank and the liquid level rising to the high water level setting value there is
  • smart toilet shown includes a ceramic body 10, wherein in a front Section of the ceramic body is provided with a collecting basin for excrements, and wherein the ceramic body has a flushing water channel 14 at the rear in the upper area of the collecting basin and a waste water pipe 16 at the rear in the lower area of the collecting 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 takes place.
  • the flushing water channel 14, the collecting basin 12 and the waste water pipe 16 are conventional constructions for ceramic bodies, so that reference is made to ceramic bodies according to the prior art. The following is a description of the construction and operation of the flushing system 20.
  • the flushing system 20 includes an electromagnetic valve 21, a water tank 22, a water pump 23 and a float liquid level switch 24.
  • the float liquid level switch 24 protrudes into the water tank 22 and controls the closing of the electromagnetic 21 valve when the liquid level of the water tank is high Water level set value reached (blocking of the water supply to the water box).
  • the liquid level float switch 24 controls the opening of the electromagnetic valve 21 when the liquid level of the tank decreases to a low water level setting (water supply to tank).
  • a water outlet port 212 of the electromagnetic valve 21 is connected to a water inlet port 221 of the water tank 22 through a water pipe.
  • a water outlet port 222 of the water box is connected to a water inlet port of the water pump 23 through a water pipe 25 .
  • a water outlet port of the water pump 23 is connected through a water pipe 26 to the flushing water channel 14 of the ceramic body.
  • the water inlet port 221 is at the top of the water box 22 and the water outlet port 222 is at the bottom Water box arranged, wherein there is an air gap between the water inlet opening 221 of the water box and the liquid level rising to the high water level setting. This air gap means that water, after entering through the water inlet opening 221, has to fall a certain distance before it hits the water in the water box.
  • 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 electromagnetic valve 21 opens automatically and external water is supplied to the water box 22 through the electromagnetic valve water inlet port 211.
  • the electromagnetic valve 21 closes and the water supply to the water box 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 continuous even when the water pump 23 is not activated.
  • the liquid level of the water box 22 reaches the high water level setting.
  • the water pump 23 is not activated, no water flows into the flushing water channel 14. If a malfunction prevents the electromagnetic valve 21 from automatically closing, this results in a continuous supply of water to the water tank, the water flowing through the water line 25, the water pump 23 and the water line 26 enters the flushing water channel 14 and thus the catchment basin 12 .
  • the electromagnetic valve 21 is connected to an upper portion of the water tank 22 , the water pump 23 being 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 air gap preferably measures more than 20 mm.
  • the water tank 22 further includes an overflow opening 223 located higher than the high water level setting.
  • the overflow opening promotes air discharge when water is supplied to the water tank 22.
  • excess water can flow out through the overflow opening.
  • the overflow port 223 is higher than the position of connection between the water pipe 26 and the flushing water passage 14. If the electromagnetic valve 21 cannot be automatically closed and water continuously flows to the water tank, excess water enters the flushing water passage 14 and flows not from the overflow opening 223.
  • an upwardly extending water inlet chamber 224 is arranged on the upper side of the water tank 22, the water inlet opening 221 of the water tank is provided at the upper end of the water inlet chamber 224, with the electromagnetic valve 21 and the float liquid level switch 24 on the upper side of the water tank 22 are attached, with on the top of the Water tank 22 is also provided with an enclosure 225 which encloses the water inlet chamber 224, the electromagnetic valve 21 and the float liquid level switch 24, and wherein the enclosure 225 is provided with a centering recess associated with the water inlet opening 211 of the electromagnetic valve 21.
  • the intelligent toilet also includes a base plate 30 and a control module 40 activation and deactivation of the water pump 23, wherein the base plate 30 is connected to a bottom surface of the interior of the rear portion of the ceramic body 10, and wherein 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, and 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.
  • connection 50 On the outside of the connection 50 there is a thread and a threaded nut 54 for the rotary connection, 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 line 26 can be guided through the connection and the plastic part from the outside inwards 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.
