| PURPOSE:To stably obtain hot water by directing condensed water exactly to the inner surface of a can by a method in which a heat exchanger is set in an one-way inclined spiral form in the can, receiving trays are spirally provided in the lower part of the heat exchanger along it in a continuous manner, partition plates are provided on the ways of the receiving trays, and the surface of the inner cylinder is wrapped with a wick from the liquid trap portion to the upward direction. CONSTITUTION:When a working liquid 6 is heated by a heating burner 7, the liquid 6 is given the evaporation latent heat in a vacuum can and becomes vapor in the can. When the internal pressure of the can reaches the set pressure of a pressure switch 10 to detect the internal pressure, a valve 11 is closed and at the same time the burning of the burner 7 is stopped to keep the internal pressure of the can at a set pressure all the time. When cold water is introduced from a water supply port 3a into the heat exchanger 3, the vapor is condensed on the outer surface of the exchanger 3 by cooling and the condensed liquid drops through receiving trays 4, spirally flows down the outer surface of the inner cylinder 2, and is trapped in the liquid trap formed by the partition plates 12. The whole outer surface of the inner cylinder 2 can thus be wetted by the wick 5 rising from the liquid trap. | ||||||

| PURPOSE:To obtain hot water of desired temperatures instantaneously without the needs to circulate water to be heated by providing a pressure reducing arm involving a pressure-reducing tube and a hot supply tube is provided for a hot water storage and supply tube. CONSTITUTION:When a device is actuated, a burner 2 is ignited, and water 19 is partly evaporated until the pressure of a pressure-reducing tube 17 reaches a given pressure. The burner 2 is then extinguished. When a hot water supply stopper 11 is closed, the burner 2 is ignited only for supplementing the released heat quantity. Since the tube 17 and a pressure-reducing arm 18 connected to the tube 17 are an enclosed container with a boundary face between gaseous and liquid phases, the internal temperature is kept constant if the pressure is made constant. When the stopper 11 is opened, hot water of a desired temperature set by the pressure begins to go out, and also when low-temperature water is flowed in from a water supply tube 8, the steam is condensed, the water is heated by the latent heat of the evaporation to raise the temperature of water to a desired temperature immediately. When the steam is condensed and the pressure is reduced, the burner 2 is soon ignited and continues to burn with a given combustion rate. | ||||||

| PURPOSE:To improve the reliability, the energy saving and the maintenance of the titled device by a method wherein the discharging of uncondensed gas from a vacuum hot-water heater is performed by utilizing the energy of exhaust gas discharged into a normal atmosphere, in the manner different from the conventional type device using a vacuum pump or a electrical heater and the like. CONSTITUTION:A gas collecting pipe 9 of the uncondensed gas is connected with a hot-water heat exchanger 7, and a uncondensed gas containing vessel 10 is annexed. The uncondensed gas is collected inside of said containing vessel 10 via the gas collecting pipe 9 and a valve 12 of an introducing pipe 11. The containing vessel 10 is exposed at its outer periphery surface to the atmosphere, the temperature on the inside surface of the containing vessel is made lower than both of a sealed can body 1 and the hot-water exchanger 7. A moisture vapor accompanied with the uncondensed gas is condensed inside of the containing vessel 10 and returned to the sealed can body 1 by communicating pipe 13 via a valve 14. On the other hand, another introducing pipe 15 is introduced to the inside of a smoke passage 6. The location of an introducing pipe 16 inside of the flue is higher than the fluid layer part located at the lower part of the communicating pipe 13, thereby the structure is contrived to prevent the inside of the introducing pipe 16 from the staying of the fluid. The location of the lowest part of the communicating pipe 13, that is, the location of introducing pipe 16 inside of the flue is constructed to be higher than the fluid level of the heating medium fluid collecting vessel inside of the sealed can body 1. | ||||||

| PURPOSE:To enhance the heat transfer efficiency of a hot water device by blocking by a lower header plate the lower section of many water tubes which connect an upper header to the lower header plate, and opening a circulating hole at the inner lower circulating tubes provided in the respective water tubes. CONSTITUTION:A combustion chamber 4 is formed of many water tube 1 groups which connect an uppr header 2 to a lower header plate 3, the lowermost end of the tubes 1 are blocked by the plate 3, and the header 2 communicates with the tubes 1. Inner tubes 5 are inserted into the respective tubes 1, the lower ends of the tubes 5 are fixed to the plate 3, and one or more holes 6 are opened at the tubes 5 in the vicinity of the plate 3. When the heat medium in the tube 1 is boiled by the heat transfer from a combustion chamber 4, the boiled water rises due to the difference in the specific gravity between the waters in the tubes 5 and out of the tubes 5 and the water falls. Accordingly, the water is flowed out from the circulating holes 6, heated, boiled out of the tubes 5 to rise, the steam in the boiled water is introduced into a steam chamber 8 and heat exchanged. | ||||||
