広いことが予測される。 Such direct contact type hot water heaters have a structure in which the water to be heated comes into direct contact with combustion gas during the process of flowing down from the heat absorption chamber above the high temperature gas supply chamber to the hot water storage section below, so thermal efficiency is low. very good,
Unlike conventional boilers that obtain hot water in a sealed container, this system heats water under atmospheric pressure, making it easy to use at home. Not only is it a good hot water, but it also incorporates the carbon dioxide gas contained in the combustion gas, so when used for bathing, it has effects such as relieving fatigue, which hot water made by heating regular tap water in a bath pot does not have. It is predicted that its uses will be quite wide.

In order for the surface of the perforated plate 6 to be able to form a water film 11 due to surface tension, the surface of the porous plate 6 must have a good affinity with water so that the water can form a thin water film 11 on both its upper and lower surfaces.
In order to form and flow, the surface must be free of oil and the inert coating that bright stainless steel surfaces have. In addition, the heat absorbing material 7 is arranged in such a manner that it does not protrude from the lower surface of the perforated plate 6 so as not to destroy the water film 11 formed in the opening hole 6b due to surface tension, as shown in part A of FIG. It is necessary to be present. 8 is heat absorption chamber 5
A water supply nozzle 9 is installed above the heat absorbing material 7 and sprinkles water to be heated onto the heat absorbing material 7, and 9 is provided above the heat absorbing chamber 5 of the heater body 1 and rises from the high temperature gas supply chamber 3.

When high-temperature gas is supplied and water is sprinkled from the water supply nozzle 8 onto the heat-absorbing material 7 in the heat-absorbing chamber 5 on the perforated plate 6, the high-temperature gas passes from the high-temperature gas supply chamber 3 through the heat-absorbing chamber 5 and reaches a lower temperature than the upper exhaust pipe 9. is discharged,
In addition, the sprinkled water is heated by the high temperature gas before flowing down through the heat absorbing material 7 along the slope of the perforated plate 6, and then flows along both the upper and lower sides of the perforated plate 6.
The water film 11 is formed and flows down to the periphery of the heater body, and from the lower end of the slope of the perforated plate 6 that is fixed to the upper four circumferential walls of the high temperature gas supply chamber 3, the area around the high temperature gas supply chamber 3 is The hot water is heated in the process of forming a water film 12 along the wall surface of the hot water tank 1 and flowing down, and further heated from the upper surface of the hot water stored in the hot water storage section 2 to become hot water at a desired temperature.

る。 In the direct contact type hot water heater according to the present invention as described in detail above, the perforated plate 6 forms a water film 11 on both upper and lower surfaces of the perforated plate 6 during the process of heating hot water, and has slopes around the four sides that allow water to flow down. The large number of openings 6b can form a water film 11 due to surface tension, and the heat absorbing material 7 is disposed in such a way that it does not protrude from the bottom surface of the porous plate 6. Water that is sprinkled onto the heat absorbing material 7 from above the heat absorbing chamber 5 and falling forms a water film 11 along both the upper and lower surfaces of the perforated plate 6 and flows down through the opening holes 6b.
Since water droplets do not fall into the high-temperature gas supply chamber 3 from the hot gas supply chamber 3, if the high-temperature gas supply chamber 3 is equipped with a burner 4 to directly burn fuel therein, the burner 44 may be misfired or the fuel may not be combusted. Water that has flowed down through the heat absorbing material 7 forms a water film 1 on both the upper and lower surfaces of the perforated plate 6.
Since a water film 12 is formed and flows down along the entire four circumferential walls of the porous plate 6 and the high temperature gas supply chamber 3, the perforated plate 6 and the walls of the high temperature gas supply chamber 3 are not overheated.
Compared to conventional direct contact type hot water heaters, high-temperature gas and water are reduced by the area of the water film 11 on the lower surface of the perforated plate 6 and the water film 12 along the entire four circumferential walls of the high-temperature gas supply chamber 3. As a result, the heat transfer efficiency of the high temperature gas is very good.
