- electric tubular heaters Form of a heating coil made of an electrical resistance wire into which Interior of the casing tube inserted and in a certain axial and radial Position opposite the jacket tube arranged in this.
- the position of the heating coil within the casing tube is determined by the fact that connection and / or fuse elements that connect the heating coil with an electrical Connect the power source, must also be arranged in the casing.
- the heating coil has one on one or both ends axial distance to the ends of the casing tube. This distance must be the further manufacturing steps, such as filling an electrically insulating however, good heat-conducting insulating material, preferably magnesium oxide, in the The casing tube must be retained.
- the heating coil is fixed at both ends. On this can be done relatively easily at one end accomplish that the heating coil or possibly already on the heating coil attached connection element temporarily with a suitable plastic part is provided, which partially protrudes into the interior of the casing tube and on supports the front edge of the casing tube. This plastic part is before the insertion of the heating coil into the jacket tube at that end of the heating coil or attached the existing connector, which is not is passed through the casing tube.
- the heaters due to the different areas of application of the heating devices, the various performance requirements of washing machine manufacturers to the heaters, the variety of safety regulations in the possible sales countries etc. the heaters to be found in practice Despite the same function, different constructions with different control and / or securing elements. This diversity in construction causes considerable storage and manufacturing costs. The differences are often less in the at least one heating element and the Basic body forming flange, but in the protection and control or Regulatory elements.
- the heaters are subject to high manufacturing tolerances, compliance with additional manufacturing steps, such as "re-cutting the pipe end", “Clean insulating compound” etc. is reached. This in turn increases the Labor costs per heater and thus the total manufacturing costs.
- the first pipe section can now be a have such an axial length that it is shorter than the heating element, so that after insertion into the first pipe section on at least one, but preferably protrudes at both ends of the first pipe section, if necessary with a connecting bolt attached to the heating coil end.

- the first pipe section and the at least second pipe section be connected so that on both sides of the junction in Inside the pipe sections, a seal is provided, which prevents penetration prevent the medium from entering the inside of the jacket tube. It is more advantageous however, if the first pipe section and the at least second pipe section are connected to one another at least in a medium-tight manner, d. H. so if the connection is designed so that the connection itself is medium-tight.
- an adhesive or a resin can be used in the connection of the two pipe sections is used together and next to the function of holding also takes on the function of sealing.
- the two pipe sections have both the same outside and inside diameter.
- the first pipe section or the at least second pipe section provided with an outer diameter that is smaller than the inner diameter of the other pipe section, the two pipe sections be connected by plugging them into each other and with one corresponding connection means, preferably an adhesive or a resin be connected to each other in a medium-tight manner.
- this enables Configuration the structure of the modular system explained in more detail below, because in one and the same inner diameter of one of the two pipe sections different other pipe sections with different outside diameters can be inserted.
- one of the two pipe sections, the first Pipe section or the at least second pipe section by inserting one of the two pipe sections is mounted in the other pipe section.

- the carrier unit can be configured in any way to accommodate the wedge. It is however, particularly advantageous if the carrier unit for receiving the expanding body has at least one opening, for example in the form of a slot. If the opening is designed as a slot, this can preferably be in one of the Planes of symmetry of the carrier unit run. This will make it even Widening the carrier unit, preferably in the directions perpendicular to the Plane of symmetry.
- the slot of the carrier unit at least has a counter-locking element, which locks the wedge in the slot cooperates in connection with the locking element of the wedge.
- the locking element of the wedge for example, a locking hook
- the locking element of the wedge for example, a locking hook
- one of externally accessible opening is preferred, by means of which the latching hook by, for example a screwdriver from its engaged position with the opening through z.
- the heating units show such Heaters often take the shape of the letter "W". Because of this often form of heating unit encountered, it is also advantageous if the carrier unit two substantially parallel pipe sections for Pick up the free ends of the heating unit and one between the pipe sections arranged and connected to these pipe sections fixing body has, which for fixing the carrier unit in the container wall opening with the Expanding body or the wedge cooperates. For all-round fixation To enable, it is also advantageous if the fixing body is preferred has the slot for receiving the wedge in its plane of symmetry.
- the fixing body over at least one web is connected to a pipe section, the width of a web measured in Direction of the axis of the pipe sections, is smaller than the longitudinal extension of the Fixing body in this direction, preferably very much smaller, and being the Webs preferably on the end of the fixing body facing the heating unit are provided between this and the pipe sections.
- the bars are as Predetermined breaking points formed when the carrier unit is fixed in the container wall opening tear off by the wedge, on the one hand it is achieved that the carrier unit can be handled as a unit before installing the heater.
- the webs are separated from the Pipe sections and / or the fixing body one for in the container wall opening securely clamped heater achieves necessary strength because of the pipe sections can now also be pushed outwards.
- the carrier unit on its At least one direction of insertion into the opposite side of the container wall has protrusion or stop running in sections. This Overhang limits the movement of the heater into the container.
- the base body formed by a flange unit which is a flange plate, a sealing plate, contains a clamping plate and a clamping unit. That in this embodiment component of the invention to be expanded and a clamping unit is the sealing plate, by means of the expanding body penetrating into it when the heating device is clamped is expanded.
- the expansion body can have the shape of a truncated cone and / or a truncated pyramid be trained. Because the used in such heaters Heating units usually have the shape of the letter "W" have Container wall openings have an oblong or oval shape. Therefore it is special advantageous if the expanding body is a combination of a truncated cone shape and has a truncated pyramid shape.
- the expansion body on the sealing plate facing side of the clamping plate is arranged. It is particularly advantageous however, if the expansion body on the side of the clamping plate facing the heating unit is provided. Here it has also proven to be advantageous if the expansion body and the clamping plate form a one-piece unit.
- the sealing plate has a recess on its side facing the heating unit has, in which the expanding body or the clamping plate when bracing with the Flange plate at least partially occurs.
- the recess can be independent of the contour of the expansion body or the clamping plate. However, it is particularly advantageous if the recess is at least approximately adapted to the contour of the clamping plate. It when the recess is frustoconical and / or is particularly advantageous is truncated pyramid.
- the flange plate can be on its outside have an at least partially circumferential collar with which they are in Support the installation position of the heating device on the outside of the tank wall.
- a particularly good sealing effect can be achieved if the sealing plate an at least partially circumferential paragraph on its outer circumferential side has with which they are in the installed position of the heater on the outside of the Container wall rests.
