Definitions

  • the invention relates to a device for evaporating water by means of electrical heating, for use in electrical household appliances and power tools, with the drip-free steam is generated in the simplest way.
  • EP 1 026 306 a steam generator with pump for an iron is described. In it, the great design effort is shown, without going into an electrical interconnection of pump and heater.
  • EP 1 151 705 known to regulate the temperature of a steam oven by supplying water to a steam generator arranged in the oven. In it, the process of steam generation is regulated by a complex measuring and evaluation system. This complex and limited to the specific application arrangement is not useful for the simplest solutions,
  • the object of the invention is a device for evaporating water by means of electrical heating, with the simplest way and with a minimum of inexpensive components drop-free steam for use in electrical household appliances and power tools is generated.
  • the advantage of the invention is that in the simplest way with a minimum of components troplenfreier water vapor is generated and the device according to the invention is used as a self-operating component use. Another advantage is that the working temperature is reached quickly due to the low-mass construction of the evaporator and by small dead times when changing the supply voltage and an immediate change in steam power.
  • the device is heated by applying the supply voltage 12 to the heating element 4 at the bottom of the evaporator 2.
  • the regulator contact 1 Upon reaching a specific temperature determined by the regulator contact 1, for example 160 ° C., the regulator contact 1 opens and switches off the heating element 4 from the supply voltage 12. As a result, a large part of the supply voltage 12 is at the regulator contact 1 and the water pump 3 begins to inject water into the water pipe 7 of the evaporator 2 via the suction hose 5 and the connecting hose 6. The water evaporates immediately in the heated evaporator 2 and is available at the steam pipe 8 drop-free as steam at high pressure. In this case, the evaporator 2 cools down and upon reaching a temperature also determined by the regulator contact 1, for example 120 ° C., the regulator contact 1 closes again, the water pump 3 no longer receives the supply voltage 12 and the heating element 4 is heated again. This process is repeated continuously.
  • a specific temperature determined by the regulator contact 1 for example 160 ° C.
  • the supply voltage 12 is completely available when heating the heating element 4 and when pumping water to the water pump 3, a small part of this voltage drops from the heating element 4. However, since the electrical pump resistance is much larger (about one hundred times) than the electrical resistance of the heating element 4, when pumping after
  • the regulator contact 1 is connected in series with the thermal fuse 9 and both are located outside of the hottest point in operation at the bottom of the evaporator 2. At this point, the water to be evaporated from the water nozzle 7 is injected inside the evaporator 2.
  • the housing of the evaporator 2 made of stainless steel sheet is thus massearm and has very short heating times.
  • the case has a volume of about 100 milliliters and is very flat.
  • the diameter of the base is about ten times greater than the height.
  • the shape of the evaporator 2 need not be cylindrical. Although this is technologically advantageous, but other geometries are suitable.
  • the evaporator 2 is inclined by the skew angle 10 to the horizontal. This angle is for example between 5 ° and 10 ° and the Inclination is always such that the water flows to the side of the water nozzle 7, ie the hottest point in operation.
  • a baffle plate 11 in front of the steam pipe 8. This prevents bubbling water from coming out of the steam pipe 8.
