Control device for cooking appts. - has conductive drum driven by motor providing variable burner cycle dependent on axial position of contact

摘要

The control device for the burner of a cooking apparatus comprises a geared-down synchronous motor (1) and a drum (2) or other rotary member which can be driven in rotation by this motor. An electric circuit is associated with the drum, comprising at least one electric contact (4) pressing upon the surface of the drum and at least one electrically conductive area (10) arranged on the drum in such a manner as to permit operation of the burner according to a cycle which is variable as a function of the axial position of the contact (4) on the drum. Adjustment of the position of the contact in relation to the conductive track permits the duration of the heating portion of the cycle to be varied progressively and continuously. The rotary member may alternatively be a disc on which the contacts is radially adjustable. A safety arrangement for cutting off gas if the burner does not ignite is described.
