摘要： PROBLEM TO BE SOLVED: To achieve good vaporization and power saving, by measuring the temperature which is highly related to the temperature of a vaporizing surface that vaporizes fuel by a temperature sensing means in a vaporizer which is equipped with a heater. SOLUTION: Since a temperature sensing means 34 is provided at a location other than right above a heater 24 on the upper surface, the temperature sensing means 34 hardly receives the influence of variation of heat generated by the heater 24. Moreover, the temperature sensing means 34 can measure the temperature which is highly related to the temperature by a vaporizing surface 27 which vaporizes liquid fuel, and also the control of the heater 24 for good vaporization can be performed. Further, wasteful electric conduction to the heater can be cut down, so that there is an effect of achieving power saving.

摘要： PURPOSE:To obtain a combustion apparatus in which a varying width of a combustion amount is wide, wind speed resistance at all the amounts is excellent, a back fire at the time of ignition is prevented and ignitability is excellent. CONSTITUTION:The combustion apparatus comprises a blower 29, a primary air passage from an air supply box 31 to a primary port 21, a secondary air passage from the box 31 to a secondary port 34, and a damper 33 so provided that a passage resistance to the primary passage is large at the time of closing and small at the time of opening, wherein, when a combustion amount is a set value or less, the damper is set to a closed position, and when it is the set value or more, the damper is set to an open position. Thus, the port 21 is cooled without increasing an air amount at the time of high combustion to prevent red-heating. Since the state that a high air flowing pressure state can be maintained in an entire combustion amount varying width range, the air mount is scarcely changed at an air supply from an exhaust side, and hence excellent burning state can be maintained.

CONSTITUTION:When a bath remote controller 36 is closed, a switching valve 26 is opened, water fed from a feed water tube 34 is heated by a heat exchanger 18, and fed to an ejector 25. The water fed to the ejector 25 is fed at a high speed to a separator 32. In this case, when a switching valve 30 is opened, part of exhaust gas of hot water heating means 20 is sucked to the ejector 25 by sucking action of the ejector 25. In this case, carbon dioxide in the gas is dissolved in warm water, and poured as hot water in which carbonic acid is dissolved in a bathtub 11 through a hot water pouring tube 33 and a forward tube 14. In order to bubble in a state that a bathtub 11 is fully filled, a bubble switch of the controller 36 is closed to operate a circulating pump 39, a switching valve 41 is opened to inject bubble water flow from a bubble injection nozzle 40 to the bathtub 11.

摘要： PURPOSE:To prevent the staying of condensate, produced by the condensation of combustion gas in an introducing passage, and prevent the deterioration of solubility due to the lowering of amount of combustion gas introduced into a mixer, in a hot-water supplier obtaining hot-water containing carbon dioxide gas by solving the carbon dioxide gas in the combustion gas into the hot-water. CONSTITUTION:Carbon dioxide gas in combustion gas, introduced by a mixer 17 provided in a hot-water supplying passage 14a through an introducing passage 16, is solved into hot-water and the hot-water, in which the carbon dioxide gas is solved, is separated from unsolved gas by a separater 19. A condensate chamber 23 is provided in the introducing passage 16 while the condensate chamber 23 is connected to the separater 19 by a condensate passage through a condensate regulator. Accordingly, the carbon dioxide gas, separated in the separater 19, is recontacted with the condensate in the condensate passage and is solved.

摘要： PURPOSE:To prevent a drop in solubility as caused by degassing of a carbon dioxide gas in a combustion gas dissolved in the hot water with a mixer in a water heater for obtaining hot water containing the carbon dioxide gas. CONSTITUTION:Carbon dioxide gas in a combustion gas is dissolved in hot water with a mixer 17 provided in a hot water path 14a and the hot water having the carbon dioxide gas dissolved is separated from the gas undissolved with a separator 19. The mixer 17 is provided on the top surface of the separator 19 vertically and a discharge port 17a of the mixer 17 is penetrated sticking out into the separator 19. Thus, the carbon dioxide gas is dissolved contacting the hot water again as it tends to retain at an upper part even when degassing occurs until the carbon dioxide gas dissolved in the hot water with the mixer 17 reaches the separator 19.

摘要： PURPOSE:To let some one taking a bath to know that carbon dioxide is dissolved in hot water when the person is taking a bath in terms of a hot water supply heater which dissolves carbon dioxide in combustion gas into hot water and supplies carbon dioxide gas-contained hot water. CONSTITUTION:Carbon dioxide in combustion gas is dissolved into hot water by means of a mixer 17 installed to a hot water supply passage. A separator 19 is used to separate the hot water into carbon dioxide-dissolved hot water and undissolved hot water. A adding apparatus 23 is installed, which is communicated with the separator 19 and inserts an addition agent 24 which chemically reacts with carbon dioxide. The additive is added into the separator from the adding apparatus communicated with the separator by an addition controller where it is forced to chemically react with the carbon dioxide and the dissolved hot water is arranged to be confirmed through visual sense such as white and cloudy and coloring.
