Laundry Dryer Intermittent Heating Control to Reduce Power Consumption

The heating unit operates in periodic cycles with multiple stages: a first period with intermittent heating (heating unit turned on and off repeatedly), a second period with continuous heating, a third period with alternating high and low power output, and a fourth period with continuous high power. This periodic operation pattern reduces overall power consumption while maintaining effective drying through cumulative thermal effects and moisture removal cycles.

The heating unit's power output parameter is dynamically changed throughout the drying process. It transitions from intermittent low-power operation in the first period to continuous operation in the second period, then alternates between high and low power in the third period, and finally maintains continuous high power in the fourth period. This parameter variation optimizes both energy efficiency and drying performance.

The drying process is segmented into four distinct periods, each with specific heating patterns: first period (intermittent heating to initial drying), second period (continuous heating to accelerate drying), third period (alternating power to maintain drying while reducing energy use), and fourth period (continuous high power to complete drying). This segmentation allows the system to achieve effective drying within a reasonable time frame while managing power consumption.

The blower operates continuously throughout all four periods to maintain air circulation and moisture removal, ensuring that the drying action continues without interruption. The heating unit complements this continuous blower operation with its periodic heating cycles, ensuring that useful drying action is maintained throughout the entire process.
