Patent number: 11920289Abstract: A heating device of a clothes drying treatment device executes an on or off operation in a temperature interval. When the temperature in a drum reaches an upper limit value TDx of the temperature interval under an action of the heating device, the heating device is turned off and the heating device stops heating. The upper limit value TDx decreases as a number of off times x of the heating device increases. Accordingly, a higher initial off temperature is adopted for the heating device, the temperature in the drum rapidly increases to the drying temperature, a preheating time is shortened, and a certain coefficient is multiplied in following control parameters controlling on or off of the heating device. The coefficient is related to the number of on-off times, and the effect is achieved that the off temperature of the clothes dryer gradually decreases as the number of on-off times increases.Type: GrantFiled: April 30, 2019Date of Patent: March 5, 2024Assignees: QINGDAO HAIER LAUNDRY ELECTRIC APPLIANCES CO., LTD., HAIER SMART HOME CO., LTD.Inventors: Jun Wu, Wenwei Li, Guanghui Pan, Yubao Wang, Guangfeng Wang

Patent number: 6739069Abstract: An automatic clothes dryer has a drying cycle followed by a cool down cycle where the cool down cycle is terminated when the sensed output temperature of the dryer drum falls below a default temperature value preselected or altered by user. This permits the user to adjust the termination cool down cycle temperature to the user's preference and touch sensitivity to the warmth of clothing removed from the dryer. The user adjusts the setting of a user variable selection device on the dryer control panel to a preferred temperature signal representing the desired temperature of articles in the dryer when the cool down cycle is terminated. The dryer has a comparator that is connected to the outlet thermistor for receiving the sensed signal representing the temperature of the air leaving the drum and that is connected to the user variable selection device for receiving the user preferred temperature signal.Type: GrantFiled: October 23, 2002Date of Patent: May 25, 2004Assignee: Camco Inc.Inventors: Silvia Ionelia Prajescu, Hugh Howard Hunt

Patent number: 6098311Abstract: An air heating and control system, which in one application controls the diameter of a calender roll in the paper making process, includes a row of heater packs proximate to the various zones of the calender roll. Each heater pack has a plurality of electrical heating coils which are at least partially connected in parallel so that failure of one coil does not interrupt power to the remaining coils. Air flowing through the heating coils is heated to a desired temperature and impinges upon the calender roll to expand it as desired. A control system senses a defective coil, which effectively reduces current in a heater pack, and increases the voltage imposed upon that heater pack to again produce the desired power level or heating effect. Thus failure of a heating coil is immediately compensated for.Type: GrantFiled: September 16, 1998Date of Patent: August 8, 2000Assignee: Impact Systems, Inc.Inventor: Lee L. Henry
