The method includes activating the heating element until a temperature of the steam generating device reaches a predetermined upper limit. Water is introduced into a tank of the steam generating device at a predetermined flow rate and the temperature of the steam generator device is measured as the water is introduced. The flow rate of water is reduced when the temperature of the steam generator device drops below a lower limit.Type: GrantFiled: June 17, 2008Date of Patent: April 24, 2012Assignee: Miele & Cie. KGInventors: Michael Finke, Hartmut Linnemann, Robert Muether, Dirk Sieding

Publication number: 20120017464Abstract: An apparatus includes a mechanical refrigeration cycle arrangement in turn including an evaporator, a condenser, a compressor, and an expansion device, cooperatively interconnected. A drum is provided to receive clothes to be dried. An auxiliary heater is included, as is a duct and fan arrangement configured to pass air over the condenser and the heater, and through the drum. A sensor is located to sense high side temperature and/or high side pressure of the mechanical refrigeration cycle arrangement. A controller is coupled to the sensor and the auxiliary heater, and is operative to: activate the auxiliary heater during a startup transient of the mechanical refrigeration cycle arrangement; monitor the high side temperature and/or high side pressure, during the startup transient; and de-activate the auxiliary heater in response to the high side temperature and/or high side pressure reaching a first predetermined value.Type: ApplicationFiled: July 26, 2010Publication date: January 26, 2012Inventors: David G. BEERS, Brent Alden JUNGE, Nicholas OKRUCH, JR., Amelia Lear HENSLEY

Publication number: 20120000088Abstract: A clothes dryer may rely on a hybrid heat source for drying clothes. In some embodiments, the clothes dryer may rely on a combination of electrical energy to power the clothes dryer and hydronic heat to dry clothes. The hydronic heat may, for example, use hot water from an outdoor wood boiler circulated into a hydronic coil. Air passing over the hydronic coil may be warmed and delivered to the clothes dryer. The hybrid heat clothes dryer may reduce energy consumption from about 27 amperes to about 3 amperes.Type: ApplicationFiled: January 31, 2011Publication date: January 5, 2012Inventor: Kurt T. Schaben

Publication number: 20110283558Abstract: A household laundry drying appliance includes a process air circuit in which process air is circulated to remove moisture contained in laundry; and a sensor placed in the process air circuit. The sensor has a head portion for detecting a predetermined parameter of the process air and a base portion for assembly. The head portion is encapsulated in a protecting structure. With the protection of the protecting structure, The head portion can be protected from water splashing thereon, and as a result, the accuracy of the sensor is effectively maintained and the evaluation of the dryness of laundry taken in consideration of the detecting value of the sensor becomes reliable.Type: ApplicationFiled: November 9, 2009Publication date: November 24, 2011Applicant: BSH BOSCH UND SIEMENS HAUSGERÄTE GMBHInventors: Huilong Feng, Wenfeng Pang, Zhihua Yan

Patent number: 8046932Abstract: A method and apparatus for operating a dryer used to reduce the moisture content of sheet material. A drying chamber is provided and includes a plurality of drying sections and a single point exhaust system. A seal section located at the input end of the dryer includes an exhaust passage through which a gas sample is drawn by a sampling fan. Gases within the seal section are a combination of ambient air drawn through restricted passages at the entry to the seal section and exhaust gas that bleeds into the seal section from the drying chamber. A controller monitors the temperature of the sampled gases and ambient air and adjusts the rate of exhaust flow from the main exhaust system as a function of the temperature differential. A heating system is also provided for heating the seal exhaust gases above the pitch condensation temperature for the flow.Type: GrantFiled: October 12, 2007Date of Patent: November 1, 2011Assignee: USNR/Kockums Cancar CompanyInventor: Bryan Wolowiecki

Publication number: 20110252663Abstract: A double pass reversing dryer provided with a main heat source for heating air passing through the upper plenum and a supplemental heat source for heating air as it passes from the upper plenum to the drying bin. When the double pass reversing dryer of the present invention is in an unbalanced state with more high moisture content agricultural material to be dried than low moisture content agricultural material to be dried, the temperature in the upper plenum is reduced and some of the air is vented directly to the lower plenum. The remainder of the air in the upper plenum is heated by a secondary heat source before the air passes into the drying bin containing the low moisture content agricultural material.Type: ApplicationFiled: April 19, 2010Publication date: October 20, 2011Inventors: David J. Ralph, Walter J. Jacobsen
