Definitions

  • the invention relates to a tap changer for a plurality of electrical consumer resistors which can be connected individually or in series and / or in parallel to a voltage source for setting the power.
  • the invention relates to a tap changer for the heating resistors of the hotplates built into, for example, electric cookers.
  • Such tap changers have a simple mechanical structure and do not require additional electronic scarf ⁇ obligations such as those required in the continuous switches which are working with phase angle control or pull method, and also used for the control of hotplates.
  • the tap changers currently used are designed as seven-stroke circuits, as described for example in DE-PS 12 39 034.
  • three heating ⁇ resistors are connected to four outputs of the tap changer, which provide in parallel the power level 100%, and individually or in series and parallel connection, the setting of another five power levels enable (the OFF ⁇ position is the seventh position of the switch).
  • the invention has for its object to provide a tap changer that allows a narrower power Unterteilu._g.
  • the invention has for its object to provide a tap changer in conjunction with the four Inputs of a hotplate equipped with three resistance heating elements can be used. "This requirement is important because the hotplate manufacturers cannot be expected to produce hotplates with changed heating resistance inputs and the tap changer according to the invention must be interchangeable with the conventional seven-cycle tap changers.
  • the heating plates with either the Phasen ⁇ voltage of 220 volts or with the line voltage from 380 volts to operate, and using three heating resistors maximum of seven switching stages (including zero ⁇ position and full load) could be achieved.
  • the invention there are numerous other possible combinations even when using the conventional hotplates equipped with four inputs, which ensure a very narrow level of power division.
  • the invention is not only suitable for setting the power of hotplates, but can also be used with other heating resistors and, moreover, also with other consumer resistors in which a corresponding power distribution is required.
  • the tap changer according to the invention can also be used for direct current operation of small and large powers.
  • the invention is illustrated below using exemplary embodiments. The drawing shows:
  • FIG. 1 shows a circuit diagram of a conventional seven-cycle step switch which feeds the three heating resistors of a hotplate; the power levels for the seven cycles are also shown;
  • FIG. 2 shows a tap changer according to the invention with a tap changer, likewise provided with four outputs, which feeds a hotplate provided with four inputs, which has the same heating resistors as in FIG. 1;
  • Fig. 3-6 different, non-limiting embodiments of tap changers or tap changers with heating elements switched on, which can be set to different power levels.
  • tap changers or tap changers with heating elements switched on which can be set to different power levels.
  • Figure 3 shows a ten-stroke tap changer to which the three usual heating resistors Nl, N2, N3 of a hotplate are connected. The percentages represent the power share in percent of the maximum heating power (resistors connected in parallel).
  • FIG. 4 shows a twelve-cycle stage circuit for a hotplate with three heating resistors N1, N2, N3.
  • FIG. 5 shows a ten-stage circuit when using only two heating resistors L and R.
  • FIG. 6 shows a tooth clock circuit for two heating resistors L and R using a diode known per se.
  • Figures 3 to 6 show the individual positions of the tap changer, which lead to a parallel or series connection, with the corresponding power level.
  • the dimensioning the resistors are made in a conventional manner so that compatibility with conventional switches and heating plates is ensured.

Abstract

On multiplie les échelons d'une commutation échelonnée, notamment des plaques de cuisinières électriques, en appliquant deux tensions d'entrée auxquelles peuvent se raccorder sélectivement les combinaisons de résistances de la plaque. Deux tensions différentes d'entrée permettent déjà d'obtenir une pluralité de possibilités de combinaison, avec par conséquence beaucoup plus d'échelons de commutation que les sept usuels de l'état antérieur de la technique. Les tensions d'entrée disponibles sont la tension composée de 380 volts, fournie par des raccordements de courant triphasé, et la tension simple de 230 volts.
