Definitions

  • the invention relates to a method for adjusting a heating power of a multi-circuit burner according to the preamble of claim 1 and an apparatus for performing such a method according to the preamble of claim. 5
  • the heating power of a dual-circuit burner can be adjusted via an electronic control device as a function of user-specified heating power levels.
  • the control arrangement regulates the partial gas flows to the inner burner and the outer burner of the dual-circuit burner.
  • a gas flow rate to the outer burner is interrupted until a low-setting power in the lower heating power range is reached, while only one gas flow rate to the inner burner is set. Between this small adjustment and the full firing of the dual-circuit burner, that is a maximum power, the gas flow is set to the outer burner.
  • the gas flow rates to the internal and external burners of the dual-circuit burner are set with complex and expensive control components.
  • the document DE 44 34 742 A1 discloses the control of a gas supply in a dual-circuit gas burner with separate control of the inner and the outer burner circuit via a gas valve with an adjusting device.
  • the document DE 199 49 600 A1 discloses a gas-fired domestic appliance with an electric Glüh primazünder for a clocked heating operation.
  • the object of the invention is a method for adjusting the heating power of a multi-circuit burner or a device for carrying out such a method to provide, in which the heating power is simplified and adjustable with reduced component cost.
  • the gas flow rate to the internal burner is set in a clock switching operation in the adjustment of the heating power until reaching the small adjustment. That is, according to the invention, the setting of the heating power in the lower power range between 0 and the low-setting power is clocked and not continuous. Elaborate control components for continuously increasing or reducing the internal burner gas flow can thus be omitted taking up space in the gas hob. In particular, if the internal burner is associated with only a small heating power range, the heating power of the internal burner can be done despite clocking with sufficient Einstellgüte.
  • the internal burner In a power range below the low-setting power, the internal burner is therefore clocked according to the invention.
  • the internal burner is operated at full load while the outside burner is switched off in order to provide the low setting power. Only with a user-side increase in the Schutulstress on the small adjustment power of the outer burner is switched on.
  • the setting of the heating power to reach the low-setting power can thus be achieved according to the invention omitting a continuously operating actuator alone by the clock switching operation.
  • the gas flow rate to the internal burner is clocked at a heating capacity below the low setting power
  • the external burner remains out of operation.
  • the internal burner can always burn at full load during the switch-on times in cyclic operation.
  • Additional control components which allow, for example, a reduced partial load operation of the internal burner, can be omitted according to the invention in the partial gas line leading to the internal burner.
  • a first and a second partial gas line may be provided, each leading a partial gas flow to the inner burner and a partial gas flow to the outer burner.
  • an actuator is connected, which allows a continuous fine adjustment of the heating power between the low-setting and a maximum power.
  • a fine adjustment by a working in continuous operation actuator is omitted in the internal burner partial gas line.
  • the guided through the inner burner partial gas line partial gas flow is adjusted by a simple clock valve, that works until it reaches the low-end setting in the cycle-switching mode.
  • the small adjustment itself is achieved by a continuous operation of the internal burner, in which the clock valve is permanently open.
  • Each leading to the inner burner and the outer burner partial gas lines can branch off from a main gas line.

  • a check valve can be connected in the main gas line, which interrupts a gas passage to the two partial gas lines.
  • the timing valve may be arranged directly in the partial gas line leading to the internal burner.
  • the blocking element can be connected directly upstream of the actuator for continuous heating power adjustment.
  • the blocking element can be integrated directly into the actuator of the outer burner partial gas line.
  • the gas paths of the partial gas streams to the inner and outer burners in a structural unit or a valve block can branch off from a gas path of the main gas stream.
  • the already mentioned check valve, the timing valve and the actuator can be integrated space-saving.
  • the check valve may preferably be formed as a linearly adjustable locking member in the assembly. The locking member can be adjusted between a blocking position in which the gas paths are interrupted, and a passage position in which the gas paths are opened. In the passage position of the locking member, the internal burner can be subjected to full load.

  • the timing valve may be provided in the assembly or the valve block directly in the main gas path. As mentioned, the clock switching operation takes place when put out of operation outside burner. This means that in the valve block on the one hand, the locking member is in the passage position, on the other hand, however, the actuator keeps the flow passage to the outer burner still closed.
