摘要： PROBLEM TO BE SOLVED: To provide a gas mixing method and a gas mixing device to improve the mixing of difference kinds of gases and realize uniform flow velocity distribution and to provide a burner to realize premixed lean fuel combustion. SOLUTION: Second gas, such as fuel gas (G) alone, air (E) alone, or air-fuel premixture (f) of air and fuel gas is caused to flow in a direction crossing first gas by using a second passage part (a fuel passage part 16), a rectifying means (an orifice 34), a nozzle part (24) and the like into the first gas, such as air (E) alone, fuel gas (G) alone, or air fuel premixture (f) of air and fuel gas, flowing in a specified direction by using a first passage part (an air passage part 14), and a rectifying means (a passage hole 20), to generate air-fuel mixture (F). A gas mixing method or a gas mixing device described above is provided. A burner to burn the air-fuel mixture is realized, the mixture of different kinds of gases is improved, uniform flow velocity distribution can be realized, and in the burner, premixed lean fuel combustion can be realized.

摘要： PROBLEM TO BE SOLVED: To provide a high convenience burner and a mixed gas formation method by ensuring stabilization of combustion and the low manufacturing cost. SOLUTION: A burner includes main flame hole sections (12, 12A, 12B) and a flame insulation sections (16, 18, 17), and further includes mixing passages (20, 20A, 20B) that form mixed gas (F), air passages (21, 21A, 21B), fuel passages (22, 24, 23), and throttle sections (26, 26A, 26B) for narrowing a passage cross section in the course of the mixing passage. Hereby, the fuel gas (G) is injected in the direction opposite to an air direction (E) or an intersecting direction or an orthogonal direction to form the mixed gas (F) for stabilization of the combustion, reduction of the manufacturing cost, and convenience.

摘要： PROBLEM TO BE SOLVED: To provide a bath hot water heater to provide further facility. SOLUTION: A water pressure sensor 47 to measure a pressure of hot water flowing through a pipe is situated in return line 31 of circulation line for a bath between a hot water outlet 41 from a bath tub 27 and a pump 33. When a state that the bath tub outlet 41 is closed during circulation of hot water occurs, the output value of the water pressure sensor 47 is lowered and based on a change of the output of the water pressure sensor, a controller stops the pump 33 for a given time.

摘要： PROBLEM TO BE SOLVED: To perform an optimum air conditioning control in response to cases of clothing drying or wall face drying in a bathroom. SOLUTION: A hot water air conditioner 10 comprises an indoor machine comprising indoor units 16, 18 installed in an attic space above a bathroom 100 and a dressing room 102 to be heated, dried and ventilated and the like, an outdoor machine 14 installed outdoor, a main remote controller 104M installed on an inner wall face in the dressing room 102, a sub remote controller 104S installed in a remote place such as kitchen and the like. In the case of drying clothing in the bathroom 100, a flap is positioned at an angle of approximately 90 deg. to a ceiling of the bathroom 100 so as to make air flow in an arrow A direction shown in Fig. In the case of drying wall face, the flap is positioned at an angle of approximately 35 deg. to the ceiling so as to make the air passed in an arrow B direction shown in Fig. By this method, effective drying can be accomplished respectively in clothing drying and wall face drying.
