Definitions

  • the invention relates to a heatable cistern for an intelligent toilet.
  • a modern intelligent toilet has a wide range of functions. It is usually provided with a function for cleaning a human body.
  • a heating function is integrated into a cistern adapted to the intelligent toilet, so that the cistern can provide warm water for an intelligent cleaning arrangement.
  • a hygienic device In the European area, because of the strict protection of potable water, a hygienic device must be equipped with a device that protects the tap water from pollution caused by backflow and meets the EN1717 standard. Therefore, in the European area, a device for preventing the backflow must be arranged in the cistern of an intelligent toilet, which usually works with an air gap, ie Tap water is first led into an open space and is then available as flushing water for the intelligent toilet via a pump. In order to save the inner space of the intelligent toilet, a heating pipe is often arranged in the cistern, which, in compliance with the EN1717 standard, provides the warm water required for cleaning.
  • the temperature of the discharged water is very unstable, especially during the water supply in which the cold water is mixed in a large amount. This leads to a rapidly fluctuating temperature of the discharged water and impairs the comfort during use.
  • a heatable cistern for an intelligent toilet which has a body, wherein a partition is arranged in the body, which divides the interior space into an upper and a lower water chamber. Water enters the lower water chamber through a water inlet.
  • the invention is based on the object of creating a cistern which both prevents the water from flowing back into the water supply and provides an improved heating effect.
  • a heatable cistern for a smart toilet comprises a body on which a water inlet and a water outlet are provided, and a heater, wherein a partition is arranged in the body, which divides the interior of the body into an upper water chamber and a lower water chamber, wherein the upper water chamber and the lower water chamber are connected to each other, the heater is arranged in the lower water chamber, the water inlet is located in an upper part of the body and is connected to the upper water chamber, and the water outlet is located in the lower water chamber and connected to the lower water chamber.
  • An overflow opening is provided in the upper water chamber, the height of which is lower than the height of the water inlet.
  • a heatable cistern for a smart toilet comprises a body 10 and a heater 20.
  • a water pipe leads the water into the body 10.
  • the heater 20 is provided for heating the water in the body 10.
  • the heated water is drained away in order to be available for an intelligent cleaning arrangement.
  • a water inlet 11 and a water outlet 12 are provided on the body 10.
  • a partition 13 is arranged in the body 10, which divides the interior of the body into an upper water chamber 14 and a lower water chamber 15, the heater 20 being arranged in the lower water chamber 15.
  • the upper water chamber 14 and the lower water chamber 15 are connected to each other.
  • the water inlet 11 is located in the upper part of the body and is connected to the upper water chamber 14.
  • An overflow opening 16 is provided in the upper water chamber 14, the height of the overflow opening 16 being lower than the height of the water inlet 11.
  • the water outlet 12 is located in the lower part of the body and is connected to the lower water chamber 15.
  • the water from a water pipe is introduced into the upper water chamber 14 and relaxed in the process before it flows from the upper water chamber 14 into the lower water chamber 15 for heating. As a result, no pressure is built up in the water in the body 10, which effectively prevents the water from flowing back from the cistern into the water pipe.
  • a water duct is formed which connects the upper water chamber 14 with the lower water chamber 15 so that the water in the upper water chamber can flow into the lower water chamber without extensive heat exchange between the to effect warm water in the lower water chamber and the cold water in the upper water chamber.
  • the water duct can also be provided directly in the partition 13.
  • a degassing line 30 is also provided. One end of the degassing line 30 is led into the lower water chamber 15 and is located in an upper part of the lower water chamber. The other end extends out of the body 10. The fact that the degassing line is provided in the lower water chamber means that gas produced in the lower water chamber can be effectively removed while the water is being heated. Together with the blocking of the partition wall, an increase in pressure in the body can also be avoided.
  • a degassing pipe 40 is provided on the partition 13. The degassing tube 40 forms an opening at one end on the lower side of the partition wall and extends upwardly out of the body 10. The interior of the degassing pipe 40 forms the degassing line 30. The degassing pipe 40 can quickly discharge the warm gas in the upper part of the lower water chamber 15.
  • the water outlet 12 is located on one side of the lower water chamber 15. Near the water outlet, the lower water chamber has a constriction 152 which has a reducing flow area in the direction of the water outlet.
  • a mixing recess 154 is provided on an inlet side of the constriction in the lower water chamber. Since after the heating by the heater the warm water over the there is cold water, the water is stratified even in the lower water chamber 15 because of the temperature. As a result, the water initially moves back and forth in the mixing recess 154 during discharge before it is discharged from the water outlet 12 via the constriction 152 in order to stabilize the temperature of the discharged water.
  • the water outlet 12 is oriented upward, and a water outlet end of the constriction 152 is disposed obliquely downward such that the water outlet end of the constriction is aligned with a filling recess 156 and the water outlet 12 is just above the filling recess 156.
  • the filling recess 156 can slow the drained water and smooth the flow.
  • the heater 20 comprises a coiled heating tube that effectively increases the heating surface.
  • a barrier 17 is provided on the side of the heating pipe. The barrier 17 directs the flow of water to flow along the heating pipe, thereby increasing the heating efficiency.
  • a water drain is provided at the bottom of the lower water chamber 15, in which a water drainage arrangement 50 is provided.
  • the water drainage arrangement comprises a spring 52, a sealing plug 54 and a base 56, wherein the base 56 is mounted in the water drain, wherein a water opening is provided on the base 56, and the sealing plug 54 from above due to the bias of the spring 52 downwards the water opening closes. If the water in the body 10 has to be emptied as required, the sealing plug 54 is simply pushed upwards, which enables the body to be cleaned easily.
  • a level sensor 60 is provided in the upper water chamber 14.
  • the water inlet 11 is connected to an electromagnetic valve 70.
  • the level sensor 60 is connected to the electromagnetic valve 70 for communication. As a result, if the level is too low, the electromagnetic valve 70 is opened to refill water, and if the level is too high, the electromagnetic valve 70 is closed to stop refilling.
  • the water outlet 12 is connected to a water pump 80, and the water pump 80 sucks the warm water from the lower water chamber 15 and supplies it to the intelligent arrangement.
  • the body 10 has an upper cover and a base plate, which facilitates the assembly of the partition wall 13.
