|20130312700||RICH-LEAN BURNER - A rich-lean burner includes an inner cylinder to which lean gas, which is a mixture of gas and combustion air, is supplied, and an outer cylinder that is coaxially disposed around the inner cylinder such that rich gas, which is a mixture of gas and combustion air, is supplied between the inner cylinder and the outer cylinder. A burner head, which has small holes and whose diameter decreases toward the leading end, is provided on an opening of the inner cylinder. The burner head is obtained by forming a perforated metal, in which the small holes are arranged in a zigzag manner, into a conical shape. An interval between each of the small holes is two to three times the diameter of the small holes. The total area of the small holes is larger than the area of an upper end opening of an upper inner cylinder.||11-28-2013|
|20130214053||WATER HEATER - A water heater includes a bypass that is formed, on the side of a water supply pipe, branching from a main water path and bypassing a part of the main water path, and a flow path switching unit (a valve and a stepping motor) that is formed at a branching portion of the main water path and the bypass. The flow path switching unit is controlled by a controller and that can selectively switch a flow path between the main water path and the bypass. A microbubble generator generating microbubbles is provided on the bypass, the microbubble generator including a water agitator portion, a compression portion and a decompression portion. When the controller determines that scale has built up, the flow path is switched to the bypass by the flow path switching unit, and water containing microbubbles is caused to flow inside the water heater.||08-22-2013|
|20120244482||RICH-LEAN BURNER - In a rich-lean burner, a gap formed between a lean-flame port and a rich-flame port is in fluid communication with a supply passage through which a lean gas is to be supplied to the lean-flame port. One or more projections are provided on at least one of partition plates disposed between the gap and the lean-flame port and between the gap and the rich-flame port. A recessed portion is formed at a region adjacent to the lean-flame ports at an interface between the distal end of at least one of the projections protruding from one of the partition plates and the other of the partition plates, the distal end of the at least one of the projections being partially not in contact with the other of the partition plates to provide a clearance through which the lean gas is allowed to be supplied to the gap.||09-27-2012|
|20120138163||Exhaust Passage Component - An exhaust passage component includes: an inner space used as part of an exhaust passage of a hot water supply apparatus; a drainage passage configured such that if condensed water is produced in the inner space, the condensed water is caused to flow out of the inner space; a first sheet metal member, at least part of which includes a first recess formed by drawing and a plate-like portion formed around the first recess; and a second sheet metal member, at least part of which includes a second recess by drawing and a flange formed around the second recess.||06-07-2012|
|20110232502||FRYER - A fryer, each of tail pipes of a pulse combustor includes: a forward pipe that extends outward and obliquely upward from a left or right side surface of a combustion chamber to reach an inside of a cooking zone, and then bends in a C-shape along an inner surface of an oil bath, which is divided into left and right halves; and a return pipe that is mutually connected to the forward pipe in U-shape in the front side center of the oil bath, bends in a C-shape parallel to the forward pipe along the inner surface, which is divided into left and right halves, and from upper left or right of the combustion chamber, reaches an air chamber. Based on this, in the oil bath, a cooking zone in which cooking oil is heated by the surrounding tail pipes is formed.||09-29-2011|
