Definitions

• the present invention deals with a self- bearing water heater, adapted to be made of plastic material .
• available water heaters made of sheet, galvanized and/or enameled, are generally composed of a cylindrical body, vertically placed, above and below which respective caps are applied, that are slightly crowned to complete the body. This is for
• a further characteristic of the water heater of the invention is that said hollow "pulling ducts", running perpendicular to the wider container faces, are adapted to make mechanical members pass through them, like tie rods and/or bolts to secure the container itself to the wall or
• the internal container made of suitable plastic material like polyethylene or polypropylene, is obtained in two pieces, or opposed shells, joined together making their respective edges and the "pulling ducts" of each shell mate; sealing of said two shells being obtained adequately shaping said edges to allow a suitable matching thereof, downstream of which a gasket is provided running for the whole container periphery, and joining together with suitable securing means or bolts said edges, and, with suitable gaskets, the "pulling ducts" of each shell; the external container being made of ABS and the insulating material being foamed polyurethan.
• both the first and the second embodiment can be obtained through injection molding, vacuum molding, or by blowing suitable plastic material.
• FIG. 2 is a side elevation view of the internal container of the water heater, with the external container in section;
• - Figure 5 is an external front view of the water heater of the invention
• - Figure 6 is a front view of the internal container sorrounded by a stiffening tape network system
• FIG. 7 is a front elevation view of a second embodiment of the internal container
• the water heater of the invention is substantially composed of: a first, or internal container 1 made of suitable plastic material and a second, or external container 3 also made of suitable plastic material in which the first, or internal container 1 is placed after having inserted -suitable insulating material 5 between the two containers 1 and 3.
• the first container 1 is shaped as a parallelepiped, with rectangular section, where the two greater faces 7 (front and rear ones) are crossed and connected by a plurality of hollow ducts 9 perpendicular to said faces 7, running as tie rods from one face to the other.
• a plurality of notches 11 is provided in each face 7 next to each duct 9. Said faces 7 are furrowed by a plurality of external grooves 13 perpendicular to the sides and intersecting said notches 11, running as a ring on the whole periphery of the body 1 section and composing, with the above pulling ducts 9, the container 1 rib.
• hollow pulling ducts 9, running perpendicular to the wider faces 7 of the container 1, are adapted to make mechanical members pass through them, like tie rods and/or bolts to secure the container itself to the wall or for other purposes, some of which will be specified belo .
• the internal container is obtained in a single piece in suitable plastic material, such as polyethylene or polypropylene; the external container being preferably made of ABS and the insulating material being preferably foamed polyurethan.
• the internal container made of suitable plastic material like polyethylene or polypropylene, is obtained in two pieces 31, or opposed shells, joined together making their respective edges 33 and the "pulling ducts" 35 of each shell mate; sealing of said two shells 31 being obtained adequately shaping said edges 33 to allow a suitable matching thereof, downstream of which a gasket 37 is provided running for the whole container periphery, and joining with suitable securing means or bolts 39 said edges 33, and, with suitable gaskets, the "pulling ducts" 35 of each she .
• hollow space between first container 1 and second container 3 is preferably foamed polyurethan.
• the internal container 1 is designed in a suitable plastic material with such thickness as to guarantee an easy and safe operation under the various recurring operating conditions; however, for greater safety, a further safety element is provided applied to said internal container 1; this element is composed of a fencing with tapes 41, strap-type, running along the external grooves of the container itself and creating a network element around it. Said tapes 41 are adequately joined together, for example through bolts 43 or the like.
