Detailed Description of the Invention [Field of Industrial Application] The present invention is designed to prevent water falling from above from falling into the high-temperature gas supply chamber, and to prevent the water from falling into the high-temperature gas supply chamber from falling into the high-temperature gas supply chamber. This invention relates to a direct contact type hot water heater that forms a water film along the side wall and flows down, so that even when fuel is combusted within the high temperature gas supply chamber, the combustion efficiency is extremely high and the side wall of the high temperature gas supply chamber can be prevented from being burnt out. .

８２８号。Conventionally, a high-temperature gas supply chamber is provided above the hot water storage section provided at the bottom, and an endothermic chamber filled with an endothermic material is provided above the high-temperature gas supply chamber. Water is sprinkled onto the heat-absorbing material from above the chamber, and the falling water is brought into direct contact with the combustion gas of the fuel combusted in the high-temperature gas supply chamber to bring the hot water storage section at the bottom to the desired temperature. Technical ideas regarding direct contact hot water heaters with a structure for obtaining hot water are disclosed in Utility Model Publication No. 38-15983 and Utility Model Publication No. 43-31.

このような直接々触式温水ヒーターは、加熱されるべき
水が高温ガス供給室の上方の吸熱室から下方の貯湯部へ
流下する過程で直接に燃焼ガスと接触する構造であるた
めに熱効率が非常に良く。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 well.

り広いことが予測される。Unlike conventional boilers, which heat water in a sealed container, it 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.

雑な形状にルーバー加工したものであったりしたため。However, conventional direct-contact hot water heaters are flat plates with a perforated plate installed horizontally to support the heat absorbing material filled above the high-temperature gas supply chamber;
As disclosed in Japanese Patent Publication No. 983, a net-like object is suspended from the lower end of an umbrella-like object without ventilation holes, or as disclosed in Japanese Patent Publication No. 37-17440, a flame dispersion body is used. This is because the umbrella-shaped object called "Umbrella-shaped object" is supported in multiple stages with intervals, or the umbrella-shaped object is louvered into a complicated shape to prevent water from falling onto it.
構造が複雑になったり設備費が高価となったり燃焼室で
燃焼された燃料の燃焼ガスが円滑に上方に流れなかった
りする問題点があった。There were problems in that the structure was complicated, the equipment cost was high, and the combustion gas from the fuel burned in the combustion chamber did not flow upward smoothly.

なのである。In the direct-contact hot water heater according to the present invention as described in detail below, the perforated plate 6 forms a water film 11 on both upper and lower surfaces of the perforated plate 6 during the heating process of hot water, and has slopes on all four sides to allow water to flow down. The many openings 6b provided on the slope are capable of forming a water film 11 due to surface tension, and the heat absorbing material 7 is disposed in such a manner that it does not protrude from the bottom surface of the perforated plate 6. The water that is sprinkled onto the heat absorbing material 7 from the heat absorbing material 7 in the heat absorbing chamber 5 forms a water film 11 along both the upper and lower surfaces of the perforated plate 6, and flows down to the high temperature gas supply chamber 3 through the opening hole 6b. Since water droplets do not fall, if the high-temperature gas supply chamber 3 is equipped with a burner 4 that burns fuel directly within it, there is no chance of the burner 4 misfiring or worsening the combustion of the fuel. Furthermore, the water flowing down through the heat absorbing material 7 forms a water film 11 on both the upper and lower surfaces of the porous Fi 6 and a water film 12 along the entire four circumferential walls of the high temperature gas supply chamber 3 before flowing down. Also, the wall surface of the high temperature gas supply chamber 3 is not overheated, and the water film 11 on the lower surface of the perforated plate 6 is reduced compared to a conventional direct contact type hot water heater.
and a water film 1 along the entire four circumferential walls of the high-temperature gas supply chamber 3
Since the contact area between the high temperature gas and water increases by the area of the water film in step 2, the heat transfer efficiency of the high temperature gas is very good.
