れていない。Conventional technology Conventionally, there were technologies for making this type of sealed tank by lining the metal tank with glass or coating it with resin, but depending on the water quality, the glass lining had the disadvantage that it could melt and cause pinholes or cracks. However, resin coating requires complicated pretreatment and the coating film is thin, so a reliable and inexpensive method for consumer use has not yet been established.

能を集中して取り付ける構成としたものである。Means for solving the problem and description To solve the problem, the corrosion-resistant hermetic tank of the present invention uses a partially opened hermetically sealed metal tank with a flange on the upper part and a drain port on the lower part instead of a mold. , a metal-resin double layer is formed by sealingly holding the cylinder in the flange part, hanging the parison, and blow-molding while releasing gas from the drain port at the bottom, and using the metal tank instead of the mold as part of the product. A method for manufacturing a structurally corrosion-resistant sealed tank, and all necessary functions except for a drain port at the bottom are centrally attached to the flange, such as a heat exchanger, a heater, a hot water outlet, a thermostat, and other controller functions. It is structured as follows.

ランジ部に集中することにより後加工する必要はない。Effect: Due to the manufacturing method and structure described above, the present invention can form a sufficiently thick resin layer inside the metal tank, and also allows the heat exchanger and piping ports to be attached at the tie attachment part during molding. There is no need for post-processing by concentrating on a certain flange.
従って金属の耐圧力と樹脂の耐食性を兼ねそなえた信頼
性の高い密閉タンクが得られることになる。Therefore, a highly reliable sealed tank that has both the pressure resistance of metal and the corrosion resistance of resin can be obtained.

の密閉タンク１内壁に密着して成形する。FIG. 1 is an explanatory diagram of a manufacturing method showing an embodiment of the present invention. Reference numeral 1 denotes a sealed tank made of steel plates assembled in advance by welding or the like, and has a flange portion 2 at the top and a drain port 3 at the bottom. A die 4 for extrusion blow molding is hermetically held in the flange portion 2, and a parison 5 is extruded and suspended therefrom. Next, air is blown out from the die 4 into the parison 5, and while being exhausted from the drain port a at the bottom, the parison 5 is molded in close contact with the inner wall of the sealed tank 1 made of a steel plate.

兼ねた密閉タンクが容易に得られる。FIG. 2 is a cross-sectional configuration diagram showing an embodiment of a metal-resin double-structure sealed tank manufactured by this manufacturing method. 1 is a sealed tank made of a steel plate, 2 is a flange portion, 3 is a drain port, and 6 is a resin layer manufactured by the molding method explained in FIG. Reference numeral 7 denotes a mating flange made of metal or heat exchanger or heater 8. In the above manufacturing method and the above structure, the metal tank is used as it is as a mold and the resin is blow molded inside, so the metal layer and , it is easy to obtain a sealed tank that has a double structure with a sufficiently thick resin layer and has both the pressure resistance of metal and the corrosion resistance of resin.
