Abstract
A control arrangement for a gas stove, wherein the control arrangement includes a gas burner; a control element to switch the gas burner on and off; a signal transducer to generate a first signal that depends on a position of the control element; a first control apparatus to control, depending on the first signal of the signal transducer, igniting or extinguishing a flame on the gas burner; and a second control apparatus that is arranged between the signal transducer and the first control apparatus. In at least one position of the control element, a second signal is fed to the first control apparatus that simulates continuous switching on and off of the gas burner.
Claims19
A control arrangement for a gas stove, comprising:
- a gas burner that produces a flame from a flow of gas;
- a flow control valve that controls the flow of gas between a zero gas flow rate, a minimum continuous gas flow rate, and a maximum continuous gas flow rate;
- a control element to switch the gas burner between a maximum on position, a minimum on position, and an off position;
- a signal transducer to generate a first signal that depends on a position of the control element;
- a first control apparatus to control, depending on the first signal of the signal transducer, igniting and extinguishing of the flame of the gas burner;
- and
- a second control apparatus arranged between the signal transducer and the first control apparatus and structured such that, in the minimum on position of the control element, a second signal is fed to the first control apparatus that causes the first control apparatus to intermittently ignite and extinguish the flame while the flow control valve switches between only the minimum continuous flow rate and the zero gas flow rate,
- wherein the zero gas flow rate, the minimum continuous gas flow rate, and the maximum continuous gas flow rate are each different gas flow rates.

- a first control apparatus that controls, depending on the first signal of the signal transducer, igniting and extinguishing of the flame of the gas burner;
- and
- a second control apparatus that receives the first signal from the signal transducer and produces a second signal when the control element is in the minimum on position, generates a second signal, and sends the second signal to the first control apparatus, the second signal instructing the first control apparatus to intermittently ignite and extinguish the flame while the flow control valve switches between only the minimum continuous flow rate and the zero gas flow rate,
- wherein the zero gas flow rate, the minimum continuous gas flow rate, and the maximum continuous gas flow rate are each different gas flow rates.
