| 20080256824 | Method of Treating a Piece of Wood at an Elevated Temperature - The present invention relates to a method of heat treatment of a solid piece of wood, such as sawn timber. According to the method, the temperature difference between the inside temperature of the heating oven and, correspondingly, the inside temperature of the wood is maintained at a maximum of 10° C., after the level of moisture content of the piece of wood has reached the fibre saturation point of the wood. A small temperature difference such as this is maintained when the temperature is further increased until a level of moisture content is reached at which the strength properties of the piece of wood are at their best. By means of the solution it is possible to considerably reduce the formation of internal cracks in heat treated wood. | 10-23-2008 |

| 20090133283 | Relay commutation sequence for multiple element heating system - To control a temperature of a dryer system, particularly a laundry dryer, an ON/OFF relay control is employed to switch heater loads. A plurality of heating elements is used in order to more precisely regulate the temperature inside the dryer system. Further, a heating control system that includes a plurality of symmetric heating elements and a control circuit is used to maintain equal distribution of relay switching loads, resulting in an extended lifetime of each individual relay. Asymmetric heating elements may also be used. | 05-28-2009 |
| 20110296708 | SOLAR GRAIN DRYING SYSTEM AND METHOD - The invention includes an apparatus, system, and method for the drying of particulate agricultural matter, especially particulate crops, such grains. The present invention provides a crop particulate (i.e., grain) drying system utilizing solar energy to heat a heat transfer fluid or solution within concomitant forced-air and radiant heat systems which pass heated air through a crop particulate material contained within a conventional crop silo or bin. Electricity demand may be met through utilization of solar photovoltaic panels backed up by connection to an external power source (i.e. power utility). | 12-08-2011 |
| 20120079736 | DIAGNOSING METHOD FOR CLOTHES TREATING APPARATUS AND CLOTHES TREATING APPARATUS WITH REFRIGERANT LEAKAGE DETECTING MEANS - A clothes treating apparatus includes a drum configured to accommodate therein an object to be dried, an air suction device configured to form a flow path of air introduced into the drum, an air exhaustion device configured to form a flow path of air exhausted from the drum, a condenser disposed to heat air sucked into the drum through the air suction device, an evaporator disposed to cool air exhausted from the drum the air exhaustion device, and a compressor and an expander configured to constitute a heat pump together with the condenser and the evaporator. The method includes a temperature detection step of detecting a temperature change of air passing through the condenser or the air suction device, and a determination step of determining that refrigerant leakage has occurred when a temperature decrease amount measured in the temperature detection step is more than a predetermined level. | 04-05-2012 |
| 20130333238 | WASTE HEAT RECOVERY AND STORAGE SYSTEM FOR A DISHWASHING APPLIANCE - A dishwashing appliance is provided having features that allow for the recovery, storage, and use of heat energy present in fluids that have been used in a cycle of the appliance such as for washing or rinsing. Before or during the draining of such fluid from the appliance, the heat is captured as latent heat using a heat transfer pipe containing a phase change material. This heat can be transferred to another phase change material and stored as latent heat. The stored heat is then transferred to air or a clean fluid such as e.g., fresh water for use in another cycle of the appliance. | 12-19-2013 |
| 20150020406 | DISHWASHERS HAVING PHASE CHANGE MATERIALS - Dishwashers having phase change materials are disclosed. An example dishwasher for treating dishes according to a cycle of operation includes a tub defining a treating chamber with an opening, a door movably mounted to the tub to selectively open and close the opening, and a phase change material part of at least one of the tub or the door, wherein the transition temperature of the phase change material is below a maximum temperature of the cycle of operation, and wherein the phase change material releases heat during a drying portion of the cycle. | 01-22-2015 |
| 20150121718 | Clothes Dryer And Control Method Thereof - A clothes dryer and a control method thereof are provided. The clothes dryer includes an air circulation system and a refrigerant circulation system, the refrigerant circulation system includes a compressor, a condenser, a throttling element and an evaporator; the air circulation system includes a filter device, an air circulation power fan and a roller, and the refrigerant circulation system does not include a subcooler; the clothes dryer further includes a controller, a temperature sensor or a temperature-sensing element, and a temperature and humidity sensing element; the controller is configured to control an operation of the refrigerant circulation system, the operation of the clothes dryer includes a temperature rise phase and a basic drying phase, and the compressor of the clothes dryer is configured to have a higher power consumption in the temperature rise phase than in the basic drying phase, to rapidly rise a temperature in the clothes dryer. | 05-07-2015 |

The invention aims to suck away moist air stagnated under the housing ( | 11-20-2008 |
| 20100107439 | High efficiency drier - A drier for drying wet material includes a drying chamber receiving material to be dried. Heating fluid is flowed generally overall concurrently with the material through at least a portion of the chamber and drying fluid is flowed generally overall countercurrently relative to the material through at least part of the chamber. | 05-06-2010 |
| 20120317832 | ENERGY EFFICIENT CYCLE FOR CLOTHES DRYER - Energy efficiencies are achieved in a dryer or washer/dryer by selectively varying temperature ranges, time periods, heater power levels, and air flow rates. Efficiency improvements on the order of 16% were obtained over typical constant power, constant temperature, timed drying cycles by varying one or more of these parameters. Efficiencies can also be improved by drawing air from alternative warm sources such as an attic or warm external environment, or by heat recovery from dryer exhaust passages. | 12-20-2012 |
