Claims
- 1. A control instrument for electric hot plates with an adjustable quantizing power control device which has manually, substantially continuous adjusting means and supplies power to the electric hot plates in individual power pulses, comprising; an expansion member with an electrical heating means, and a time switch, which for a period of time, increases the output of the power control device in an initial cooking phase, the time switch including an electronic counter as a timing member and at least one divider which, by means of an electronic switch element, reduces the power supplied to the heating means in a predetermined division ratio, wherein the time switch, which can be switched on in a lower power, continuous cooking range, can be automatically switched on by the manual adjusting means being adjusted to a power setting in the continuous cooking range.
- 2. A control instrument according to claim 1, further comprising means for automatically switching off the time switch responsive to the adjusting means being adjusted to a setting exceeding the limit of the continuous cooking range, in a higher power, frying range.
- 3. A control instrument according to claim 1, wherein the adjusting means is a rotatable knob which switches on the time switch when rotated from the off position in the direction of increased power, but when rotated in the opposite direction, does not switch on the time switch.
- 4. A control instrument according to claim 1, wherein a contactor for producing a switching-on pulse for the time switch responsive to the adjusting means is operable between the off position and the lower, continuous power range.
- 5. A control instrument according to claim 1, wherein a contact responsive to the adjustment means is operable between the lower and the upper power ranges to produce a switching-off pulse for the time switch.
