Definitions

  • the present invention relates to a water heater, in particular a hot water tank according to the preamble of patent claim 1.
  • Conventional hot water storage tanks usually comprise an inner storage vessel for storing water, an inlet and outlet pipe connected thereto, a housing enclosing the inner storage vessel and a heat insulating layer located between inner storage vessel and housing.
  • a heating element for heating stored water to a predetermined temperature is mounted in the inner storage vessel.
  • a temperature sensor is often present in the inner storage vessel, with which it can be detected whether the water temperature in the inner storage vessel has reached the predetermined value. Once the water is heated to the set temperature, the heating element is switched off and the user can then use the water heater for showering or for another purpose.
  • the hot water flows out of the outlet pipe and is mixed via a mixing valve with cold water to produce a suitable temperature for the user.
  • cold water is continuously introduced into the inner storage vessel through the inlet pipe. If the water temperature in the inner storage vessel falls below a preset value, this can be detected by the temperature sensor, so that the heating element is turned on again. But since hot water and cold water have different densities, the hot water typically accumulates in the upper region and the cold water in the lower region of the inner storage vessel, while the temperature sensor is located mostly in the central region of the inner storage vessel. For this reason, the temperature sensor can not reflect any current change in the water temperature in the water heater during the rapid warm / cold water exchange. So it is possible for the heating element when the water temperature is already below a predetermined value is not yet turned back on. This can reduce the showering comfort due to cold water.
  • Object of the present invention is therefore to provide a water heater, which ensures a long-lived and economical operation.
  • the object is achieved by means of a water heater according to claim 1.

  • the deflection element is designed such that the water flow from the Ausftussö réelle the heating channel is deflected in an opposite direction.
  • the first heating element comprises a heating coil, wherein the heating channel is formed by the heating coil.
  • the heating coil is located above an outlet end of the inlet pipe so that the water emerging from the outlet end can flow into the heating channel immediately.
  • the heating coil is arranged in a lower half of the inner storage vessel.
  • the water heater additionally comprises a deflection element arranged above the heating coil, with which the flow direction of the water flowing out of the heating channel can be changed.
  • the deflecting element further extends downwards at the outer edge of the heating coil, so that a gap is created between deflecting element and heating coil, wherein the water flow from the heating channel can be directed through the gap in an opposite direction.
  • the first is Heating element on a transverse side of the inner storage vessel.
  • the first heating element is located on the underside of the inner storage vessel.
  • the water heater also includes a second heating element for heating located in the inner storage vessel water.
  • the second heating element is located above the first heating element.

  • the water heater further comprises a temperature sensor for measuring the water temperature in the inner storage vessel
  • the control device also comprises means for Receiving a signal from the temperature sensor, which is a water temperature value, and means for turning on the second heating element when the detected water temperature value is less than a first preset threshold, or means for turning off the second heating element when the detected water temperature value is greater than or equal to a second preset threshold, wherein the second preset threshold is greater than the first preset threshold.
  • the present invention offers the following advantages: With the heating channel of the first heating element, the cold water introduced into the inner storage vessel via the inlet tube can be preheated, so that its temperature experiences a rapid increase and thus the heating time can be reduced.
  • the first heating element is primarily for heating cold water introduced through the inlet tube and therefore may have a relatively low operating temperature, which extends the life of the first heating element.
  • the water flowing out of the outlet pipe is not subjected to any undesired reheating, so that no additional amount of cold water to be mixed has to be provided, thereby saving water.
  • the deflecting element provided according to the invention makes it possible for the preheated water to be mixed with the cold water from the water layer lying further down, thereby increasing the water temperature of this cold water layer, which leads to a further reduction in the heating time.

  • the resistance wires of the second heating element 4 can be distributed over the entire heating tube, so that the water stored in the inner storage vessel can be heated as a whole.
  • the second heating element 4 is located above the first heating element 2. In other embodiments, it is also conceivable to arrange the second heating element 4 below the first heating element 2, without the heating effect being impaired.
  • a deflection element 3 is provided at an outflow opening 21 of the heating channel A (in this case at the upper side of the heating coil), with which the flow direction of the water flowing out of the heating channel A can be changed.
  • the deflecting element 3 can also be designed such that the water flow from the outflow opening 21 of the heating channel A is directed in an opposite direction so that the water heated by the heating channel can flow into the layer of water lying below for mixing therewith.

  • This is recognized by the microcontroller in the state of the electronic switch connected between it and the second heating element 4. From a closed switch can be deduced that the second heating element 4 is turned on. In contrast, an open switch indicates that the second heating element 4 is turned off.
  • the first heating element 2 is turned on by the control device 6 (step 813) in order to avoid too rapid lowering of the water temperature in the inner storage vessel. This can be done, for example, by an actuated by the microcontroller closing the connected to the first heating element 2 electron switch.
  • the second heating element 4 is turned on, no turning on of the first heating element 2 by the microcontroller takes place, but the second heating element 4 remains still in the on state and is continuously monitored for its operating state to the first heating element 2 when the second heating element 2 is switched off to turn on.

  • a third, a fourth or more heating elements can be provided in the inner storage vessel in order to achieve a uniform temperature in the individual water layers.
  • the above configuration, in which the first and second heating elements are not to be turned on simultaneously is based on the consideration that the available power supply may not be sufficient. If sufficient electric power is available, then the first and second heating elements can also be switched on simultaneously, whereby the heating time can be reduced to a considerable extent.
