Abstract
A protective control arrangement for a clothes dryer includes a pair of electrical resistance heaters coupled in parallel across a power source. A thermostat is coupled serially with one of the heaters, and is arranged for placement in the dryer exhaust air stream. With such an arrangement, as the clothes approach dryness and a predetermined temperature is reached, the thermostat opens permanently de-energizing one of the heaters, leaving the other heater continuously energized for the remainder of the operational cycle.
Claims6
In a clothes dryer providing at least one timer controlled operational cycle for the drying of clothes placed therein, a protective control arrangement comprising:
- first and second heating means in the dryer, both energized at the start of the cycle for supplying thermal energy to the dryer for effecting drying of clothes placed in the dryer;
- and
- control means in the dryer arranged such that, upon the reaching of a predetermined temperature therein, the control means will become activated to always effect de-energization of the first heating means for the remainder of the cycle while the second heating means remains continuously energized for the complete cycle, thereby effecting a reduction of rate of supply of thermal energy to the dryer.
