Patent number: 8847130Abstract: A heating unit can reduce the rate of power consumption for heating a vehicle, so that the running distance of the vehicle is increased and hence the battery charging cycle of the vehicle is prolonged. A heating unit of a vehicle heating system includes a casing made of a metal material capable of electromagnetically shielding microwaves, a support arranged in the hollow section of the casing, a plurality of microwave absorbing/heat emitting members arranged at the support and a microwave outputting unit arranged in the casing to output microwaves toward respective microwave absorbing/heat emitting members, blown air being heated by heat generated as a result of absorption of microwaves by the microwave absorbing/heat emitting members at the time for blown air to flow from the upstream side to the downstream side in the hollow sections of the microwave absorbing/heat emitting members.Type: GrantFiled: May 9, 2011Date of Patent: September 30, 2014Assignees: Kabushiki-Kaisha TAKUMI, Kabushiki-Kaisha Lead IndustryInventors: Norio Niwa, Ryousei Noda, Hiroki Anzai

Patent number: 8692169Abstract: An electrical apparatus includes a casing, a circuit board, a top cover and an active heat-dissipating element. The casing includes a first entrance, a first receptacle, a first sidewall, and a first bottom surface. An air inlet hole is formed in the first bottom surface. A concave region is defined at a junction between the first sidewall and the first bottom surface. An air outlet hole is formed in the concave region. The circuit board is disposed within the first receptacle and has at least one electronic component mounted thereon. The top cover shelters the first entrance. The active heat-dissipating element is disposed within the first receptacle and arranged over the air inlet hole. Ambient air is inhaled into the first receptacle by the active heat-dissipating element and exhausted out of the casing through the air outlet hole, thereby removing heat generated from the electronic component.Type: GrantFiled: March 2, 2010Date of Patent: April 8, 2014Assignee: Delta Electronics, Inc.Inventor: I-Shen Lin

Patent number: 8158912Abstract: A fan apparency arrangement for an appliance is disclosed. The fan apparency arrangement includes a chamber having a port; a fan in the chamber for moving air out of the chamber, the fan having a discharge end, and an intake end having an intake tube; and a sail switch disposed in the intake tube. When activated, the fan moves air out of the chamber through the port and creates a pressure difference between opposite ends of the intake tube, the pressure difference causing the sail switch to change position and signal that the fan is activated. An appliance incorporating such a fan apparency arrangement is also disclosed.Type: GrantFiled: August 8, 2008Date of Patent: April 17, 2012Assignee: General Electric CompanyInventors: James Armstrong, Steve B. Froelicher, Cheng Qiang Ren, Christopher Mast

Patent number: 6929190Abstract: A multi-purpose heating unit is sized and configured to be used with a variety of attachments or devices to perform various functions such as heating, cooking and providing light. In particular, the multi-purpose heating unit includes a heat source which can be used with a water heating attachment, an air heating attachment, a cooking attachment, and/or a light source attachment. Each of these attachments is configured to be selectively attachable to the heat source. Advantageously, because the same heat source is used in connection with these different devices, this decreases the size, weight and storage volume of these devices. This also allows the heating unit and some or all of the desired attachments or devices to be stored and transported in a relatively small container.Type: GrantFiled: August 15, 2002Date of Patent: August 16, 2005Assignee: TAPC, LLCInventor: Trevor Adrian

Patent number: 6257230Abstract: A gas fireplace is provided having a plenum formed around at least a portion of the fireplace firebox. Room air enters the plenum and is heated by the firebox prior to venting back into the room. Two openings are provided from the outside of the fireplace housing to the plenum. The first opening allows heated air to exit the plenum, while the second opening allows cool outside air to enter the plenum. a mechanism is provided to control the amount of heated air exiting the first opening and the amount of cool air entering the second opening. By controlling the inflow and outflow through the first and second openings, respectively, the amount of the fireplace by-products generated into the room where the fireplace is located such as carbon-monoxide, nitrogen dioxide, heat and moisture are reduced.Type: GrantFiled: January 22, 1999Date of Patent: July 10, 2001Assignee: Superior Fireplace CompanyInventors: Samir E. Barudi, Rodger Duke Mitchell, John R. Kelly
