摘要： PROBLEM TO BE SOLVED: To provide a hot air heater provided with an overheating preventing mechanism which can cope with the local occurrence of overheating and an air cleaner or another hot air heater. SOLUTION: The hot air heater 1 is provided with a heating means which heats supplied air, a blowing means which blows the air heated by means of the heating means as hot air, and an air outlet 6 from which the hot air is blown out. The heater is also provided with an overheating detecting means and an overheating preventing means which controls the operations of the heating means and/or blowing means so as to ease an overheating state when the overheating state is detected by means of the overheating detecting means. As the overheating detecting means, two or more sensors 21a and 21b are arranged at a distance from each other on the air outlet 6 and its vicinity.

摘要： PROBLEM TO BE SOLVED: To easily reset a cutoff valve, self locked to a valve closing condition, to a valve opening condition, by providing a bypass passage connecting a gas inflow/outflow chambers, and interposing an opening/closing valve in this passage, in a device closing a valve hole by moving a movable piece when a valve case is tilted. SOLUTION: When a valve case 30 is tilted by a prescribed angle or more by tumbling a gas equipment 1, a movable piece 32 is dislocated from a recessed part 36b, a valve unit 31 is pressed up into contact with a valve seat 35, a valve hole 35a is closed, gas supply is interrupted. In this way, a burner and a normal fire pilot burner are extinguished, a misfire is detected by a flame detection sensor, a safety valve is closed, gas supply is placed in an interruption condition. Thereafter, the gas equipment 1 is raised, the valve case 30 is placed in an untilted condition, an operating piece 38b of the gas equipment 1 is operated, when an opening/closing valve 38 is opened, a gas inflow chamber 33 and a gas outflow chamber 34 are connected through a bypass passage 37, an internal pressure of both the chambers 33, 34 is equalized, a self lock is unlocked, a tumble gas cut off valve 3 is reset to an opening condition.

摘要： PROBLEM TO BE SOLVED: To make a stable operation of a safety device for a lack of oxygen in a combustion device. SOLUTION: There is provided a thermocouple 19 for sensing a temperature of a flame (f) at a pilot burner 17 for use in igniting a main burner 10 and the thermocouple 19 is connected to a gas safety valve 12a to detect a temperature of the flame (f) when the flame (f) is lifted up due to a lack of oxygen in indoor air and then the gas safety valve 12a is closed. A draft restricting part 6b1 or a draft controlling part 6b2 having a large area with an air opening 6a being not opened is arranged below the flame (f) at a bottom plate 6 of a case of a combustion device. In the case that a concentration of oxygen in an indoor area is a concentration value in which the safety device for lack of oxygen is not tried to be operated, the flame (f) is prevented from becoming a lift flame f1 under a flow force of draft air (g). A plurality of different kinds of bottom plates 6 having a different area of the draft restricting part 6b1 or 6b2 are prepared and they are separately used in compliance with a lifting characteristic of the type of gas used.
