摘要： PROBLEM TO BE SOLVED: To provide a steam washer with excellent handleability capable of washing with ejection of powerful steam and capable of powerfully ejecting steam just after the start of operation while avoiding the restriction on the range of movement or place of use for washing.
SOLUTION: Water in a reservoir tank 2 is fed in the pressurized state to a heat exchanger 6 whose heat source is a gas burner 4 to which fuel gas is fed from a detachable cassette type gas cylinder 5, and evaporated to be high temperature steam and ejected from a nozzle 7. A grip part 92 is made to project to a body casing 9, and by gripping the grip part by one hand, an opening/closing control valve 14 is opened by the two-stage pressing operation of a release button 15. After that, a switch 16 with an ignition mechanism is opened to ignite the gas burner. The heat exchanger is a coil-shaped pipe, and by making combustion exhaust gas pass through the pipe inward, the gas is mixed in steam through a gap 941 around the nozzle, and weak acid steam can be blown to an object of washing. The direction of emitting the combustion exhaust gas can be switched from the direction of steam ejection to the other directions.

摘要： PROBLEM TO BE SOLVED: To provide a thick and thin type gas burner which can assure the stability of flame by reliably supplying a fuel gas introduced from one gas nozzle into a sub passage as a thick gas and forming a favorable retention flame at sub burner ports. SOLUTION: A thick and thin type gas burner comprises a main structural body 10, a sub structural body 20 and a gas branch unit 30. A thin gas supplied to a main passage 12 from a main opening 34 of the gas branch unit 30 is burnt as a main flame at main burner ports 13 disposed at upper ends of the main passage 12, while a thick gas supplied from a thick gas branch opening 33 of the gas branch unit 30 by way of a communicating opening 14 of the main structural body 10 and a sub passage 22 is burnt as a retention flame at sub burner ports 23 located in the vicinity of the outside of the main burner ports 13. An outer wall which surrounds the thick gas branch opening 33 of the gas branch unit 30 is protruded from other outer walls thus making a protruding portion 35 hermetically brought into contact with a wall surface around the communicating opening 14 of the main structural body 10 so that the infiltration of air into a contact gap defined between the thick gas branch opening 33 and the communicating opening 14 can be prevented.

摘要： PURPOSE:To keep excellent burning condition at all times against temporary external disturbance and/or deterioration with age by a method wherein the number of rotation of a fan is regulated so that the detected values of the driving current or the driving voltage of a combustion fan becomes a predetermined value upon starting the operation of a combustion equipment. CONSTITUTION:The number of rotation of a combustion fan 8 is controlled in a fan control unit 11 by changing a fan driving current supplied to a DC motor 14 while the number of rotation and the driving current of the fan are detected respectively by a fan rotating number detecting unit 15 and a fan driving current detecting unit 16 while respective detecting signals are inputted into the fan control unit 11. Accordingly, the fan control unit 11 controls the number of rotation of the combustion fan 8 so as to obtain a desired rotating number of the fan in accordance with the amount of combustion while detecting the number of rotation of the fan through feedback control. A characteristic function for determining the number of rotation of the fan with respect to the amount of combustion is determined so as to obtain the optimum air/fuel ratio under a condition without external disturbance and/or deterioration with age and the like and is stored in fan control unit 11.

摘要： PURPOSE:To perform a stable combustion by a method wherein a flame hole surface of a thin flame hole structure is set to be higher than a thick flame hole, and its both sides are formed with the thin flame holes having the same height as that of the thick flame hole. CONSTITUTION:A flame hole surface of a thin flame hole structure 9 is set to be higher than a thick flame hole 5, and both side surfaces of the thin flame structure 9 are formed with the thin flame hole 4 having the same height as that of the thick flame hole 5. Due to this fact, during combustion, both sides are formed with the thick flames, the thin flames are formed at the position higher than that of both sides at the central part and then the combustion is carried out. At this time, gas injected from the thin flame hole 4 held at the same height as that of the thick flame holes 5 formed at both sides of the thin flame hole structure 9 is mixed with the thick gas, intermediate concentration of the gas is attained, the intermediate flames thick and thin concentrations is formed, the base part of the thin flame is heated, a flame hole fixing characteristic is improved and a vibratory combustion is prevented. With such an arrangement as above, it is possible to perform a stable combustion.

摘要： PURPOSE:To cause lean flames at both ends to be changed into rich flames, prevent the flames from being lifted even if the rich flames are not present at both sides by a method wherein an amount off supplying gas is increased to be discharged at lean gas injection holes located at both ends of a combustion pipe in a longitudinal direction. CONSTITUTION:In the case that a combustion occurs at a combustion device, rich gas within a rich gas chamber 2 is injected from rich side flame holes 3, ignited and then forms rich flames. After the gas is injected from each of lean gas injections holes 9 and 10 into a lean gas mixing chamber 4, the gas is mixed with air fed from an air opening 5 so as to form lean gas and then lean flame is generated above lean flame holes 7. In this case, the combustion is made stable under an effect of holding flame at the rich side flame, although both ends of the combustion pipe 1 in its longitudinal direction have no rich flame holes 3, resulting in that an effect of holding flames can not be expected. However, since a rich gas supplying amount for supplying gas at the lean gas injections holes 10 at both ends is increased, the lean gas injected from the lean flame holes 7 at this part shows a low air excessive rate, resulting in that the rich flames are generated at both ends of the lean flame.

摘要： PURPOSE:To stabilize thick and thin gas distribution by incorporating an inner combustion tube for forming a thin side passage in a combustion tube for forming a thick side passage, providing a vent hole for making a throat downstream of the tube communicate with the thick side passage, and providing an air port for introducing the external air to the thin side passage of its downstream. CONSTITUTION:An inner combustion tube 4 for forming a thin side passage 3 is contained in a combustion tube 1 for forming a thick side passage 2. A thick side burner port 5 is provided at an upper surface of the tube 1, and a thin side burner port 6 is provided on an upper surface of the tube 4 at a center in a state that the holes 5 are disposed at both sides. A vent hole 11 communicating with the passage 2 is formed at a downstream side of a throat 8 of the tube 4 disposed oppositely to a nozzle 10, and thick gas having low excess air ratio to be generated from the throat 8 is injected into the passage 2. Further, an air port 12 for introducing the external air into the tube 4 is provided at a downstream of the hole 11. Thus, thick gas is supplied from a thin side having a high internal pressure to a thick side having a low internal pressure thereby to stabilize thick and thin gas flow rate distribution.
