Definitions
- the invention relates to a water heater for quick assembly.
- Instantaneous water heaters are usually fixed to a wall prior to commissioning.
- the assembly on the one hand done quickly, easily and inexpensively, but at the same time reliable and secure. For example, if an assembly is faulty, it may cause water that is under pressure in the water line to leak out and cause damage.
- the instantaneous water heater according to the invention is based on generic instantaneous water heaters in that, in addition to a rigidly formed mounting part, it has a second mounting part as a component of the inner piping, which can be connected to a wall-side water connection and comprises at least one portion that is flexibly formed in sections.
- the water heater according to the invention allows a particularly fast wall mounting.
- a device back wall is attached to a wall.
- a main component part which carries all the essential components of the water heater, such as heating coil, electronic components and the inner casing, mounted in the rear of the device.
- the flexible end piece with connected to the wall-side water connection.
- the water heater according to the invention not only allows a particularly fast wall mounting, but also a very safe installation.
- a connection of the water heater with a wall-side water connection via a flexible extension and a connection via a rigid there is no risk of transmission of a static voltage, as it then exists when both wall connections are connected via rigid connections to the water heater.
- a flexible extension piece can be produced more cost-effectively than a rigid one.
- the use of a flexible extension allows for molding of rubber seals, which can be an even more comprehensive seal.
- the water heater has a planar heating element.
- a water heater with such a heating element can be produced particularly inexpensively.
- the use of a flat heating element, in contrast to a heating block, allows a flat device construction. This meets the aesthetic demands of consumers who prefer a flat, space-saving design.
- the section which is at least partially flexible, comprises an elastic material. It has also proved to be advantageous if the flexible end piece comprises an elastic material.
- the property of a body is referred to as elastic, after deformation by an external one
- the flexible endpiece preferably comprises an elastomer, in particular a polymer or a polyadduct.
- the section which is at least partially flexible, can adapt well to the spatial conditions.
- the elastic material comprises plastic and / or plastic with metallic and / or synthetic braiding.
- braiding a particularly advantageous pressure safety of the extension piece is achieved.
- Such protection against damage can be further improved in that the extension piece comprises a torsion protection for securing against rotation.
- the second mounting part can be fastened to the wall-side water connection by means of a union nut. If this union nut is designed to be infinitely rotating, it protects the flexible endpiece against twisting, but at the same time ensures reliable attachment of the flexible endpiece.
- the second mounting part has at its wall-side end a rigidly formed, preferably pre-curved end section.
- the extension has an inner tube made of PEX.
- PEX represents a cross-linked polymer. Due to its cross-linked cross-linking, an inner tube made of PEX has a particularly advantageous elasticity and strength. Due to its special networking, PEX is very flexible and flexible and therefore easy to assemble. When cross-linking the PEX, crystals deposit around the cross-linking points and reinforce the material, resulting in excellent tear resistance of the PEX material. In addition, use of PEX results in high fatigue strength at elevated temperatures (up to 90 °), excellent heat aging resistance, and very good chemical resistance of the inner tube.
- the extension piece comprises a braiding made of stainless steel. This provides excellent pressure stability and strength.
- the inner tube is covered by a thermoplastic elastomer and / or a polyamide braid and / or a stainless steel mesh and / or a second thermoplastic elastomer.
- Thermoplastic elastomers in some areas have physical crosslinking points that dissolve on heat without the macromolecules decomposing. Therefore, they can be processed much better than normal elastomers.
- Preferred elastomers are polyolefin elastomers of polypropylene and / or natural rubber; Depending on the quantity ratio, they cover a wide range of hardness.
- the end piece comprises an inner tube made of PEX, and adjacent thereto a thermoplastic elastomer, adjacent thereto a Polyamalidflecht, adjacent thereto a stainless steel braid, and adjoining an outer tube made of a second thermoplastic elastomer.
- the inner tube is hygienic and clean, and moreover flexible, since it can be made in a small layer thickness in this embodiment.
- the adjoining thermoplastic elastomer causes reinforcement and protection of the inner tube.
- the adjoining Polyamidgeflecht and surrounding the Polyamidgeflecht stainless steel mesh together cause a particularly advantageous compressive strength, a greatly increased bursting pressure and excellent kink resistance.
- the outer tube of a second thermoplastic elastomer provides effective protection against wear.
- its smooth surface allows easy cleaning.
- This preferred combination of different materials provides high fatigue strength of the flexible hub at elevated temperatures.
- it ensures a very good chemical resistance of the flexible endpiece; from the outside against aggressive cleaning agents, from the inside against additives in drinking water such as chlorine or fluorine.
- this preferred embodiment has excellent flexural strength.
- the water heater according to the invention provides a high degree of ease of installation while reducing assembly costs and at the same time ensures a secure and permanent installation of the device.
- Fig. 1 is an illustration of the main component part which is suspended in the rear wall; such as
- Fig. 2 is a schematic representation of a water heater in front view; such as
- Fig. 3 is a schematic perspective view of a water heater; such as
- Fig. 4 is an illustration of the structure of a flexible extension piece.
- Fig. 1 shows a main component part 3 which has been hung in a device back wall 2, which has been attached to a wall.
- the Main component part 3 which carries all the essential components of the flow heater 1 such as heating element 7, electronic components, triac cooling 10 and the inner casing 4a, 4b, 7, 9a 9b, this main component part 3 can now be folded into the rear panel 2 and screwed.
- a connection with a wall-side water connection 6 must be made.
- the flexible portion 5 extends in the diagonal direction from the wall-side water connection 6 to a center of the device on the left.
- Fig. 2 shows a water heater 1 in a front view.
- An extension piece 5 is connected to a wall-side water connection 6.
- the extension extends from the wall-side water connection 6 bottom right to a center of the device left. This allows a cost-effective and space-saving distribution of the components in the device.
- FIG. 3 shows a perspective view of a continuous flow heater 1 in a schematic representation.
- This comprises a rear wall 2, a main component part 3 and a second mounting part 4b.
- the main component part 3 comprises, inter alia, a heating element 7.
- the second mounting part 4b comprises a flexibly formed section 5. By means of this flexibly formed section 5, a connection to the wall-side water connection 6 is produced.
- the extension 5 comprises an inner tube 12 made of PEX.
- the inner tube 12 in turn is enveloped by a first thermoplastic elastomer 8b, adjacent thereto is a polyamide braid 13b, adjacent thereto a stainless steel braid 13a, and adjacent thereto a second thermoplastic elastomer 8c.
- a union nut 1 1 takes place a connection of the extension piece 5 with a wall-side water connection.
- the water heater according to the invention provides a high degree of ease of installation while reducing assembly costs and at the same time ensures a secure and permanent installation of the device.
