Definitions
- the invention relates to a water heater of the type specified in the preamble of claim 1.
- the ring seal is placed in the interior of the heating module at the end of the passage.
- the clamped earthing and adhesive clamp sits on the outer end of the radiator's connection end, which is led through the ring seal and the passage.
- the clamp is supported on the outside of the heating module and engages in a pocket formed on the heating module on one side of the passage.
- the ring seal is exposed to water, which can be hot in this area under certain circumstances.
- the radiator can move with its connecting end with the then inclined clamp to the outside and leave its target position.
- the ring seal can be gradually pushed out of its seat by the loose radiator. Replacing the ring seal requires dismantling the heating module.
- a large-area membrane made of elastic material is provided in the area of the passages for the radiator connection ends on the inside of the heating module, which serves to actuate a switch, and in the annular sealing elements for the connection ends of the Radiator are molded.
- the ring-shaped sealing elements are placed in the inner ends of the passages.
- an earthing and holding clamp is fixed, which is supported on the top of the heating module. This connection end can move outwards on the radiator and give up its target position.
- the concept of the ring seals molded into the membrane is complex and expensive.
- the invention has for its object to provide a water heater of the type mentioned, which is inexpensive to manufacture and in which each ring seal device is easy to install and reliably secured. Furthermore, a reliable securing of the position of the radiator with simple structural means should be possible.
- the ring seal arranged in the passage from the outside of the heating module has been removed from the influence of the water and can be easily installed and replaced.
- the clamp secures the ring seal directly or indirectly at the sealing point. The likelihood that the tubular heater will leave its target position is extremely low.
- the tubular heating element can be properly secured during operation if the tubular heating element has a bend which is in contact with a stop in the heating module, so that the tubular heating element cannot move further outwards, while the clamp on the connection end is supported on the outside of the heating module and prevents the connection end from migrating inwards.
- the interaction of the tubular heating element with the passage and the clamp and its shape with the stop around the heating module body result in permanent securing of the tubular heating element in the heating module and simple installation.
- the tubular heater is secured against migration outside and inward, in particular by the support of the clamp on the heating module which is effective in both directions, the clamp also taking on the task of securing the ring seal.
- the tubular heater is fixed in the passages with two connection ends, it is also prevented from rotating in the passages.
- the wiring effort for grounding the two connection ends is minimized if the connection ends are secured with a common clamp.
- the wiring effort for the grounding can be reduced even further if the clamps arranged on all connection ends are either connected to one another in an electrically conductive manner. which are combined into a multiple clamp. Only one ground wire is required.
- the clamp or the multiple clamp is an inexpensive sheet metal stamped and bent part with holding claws and at least one contact tab.
- the ring seal is expediently inserted into an extension of the passage that is open to the outside, which facilitates the assembly of the ring seal, and an annular intermediate part is placed between the clamp and the ring seal, which is inserted from the outside and fixes and supports the ring seal by means of the clamp.
- the ring seals and / or the two intermediate parts for securing the ring seals form an integral structure with the shape of an eight for the two connection ends of a tubular heating element.
- the structure can be a simple and inexpensive injection molded part made of an elastomer or plastic.
- the intermediate part is designed with an annular groove for the opening of the passage and with a pressure collar for the ring seal, the intermediate part is correctly positioned in the installed position and the ring seal is properly secured and also shielded from the outside.
- 1 is a perspective view of a heating module of a water heater before the assembly of tubular heaters
- 2 is a partial perspective view of the heating module with mounted, secured and sealed tubular heaters
- Fig. 3 shows a section of the bushing area of the connection ends of a
- Fig. 4 shows a detail section of a further embodiment.
- a water heater W shown in FIGS. 1 and 2 in particular a so-called shower heater (a device hood is omitted for the sake of clarity) has a heating module H, which in the embodiment shown is composed of two plastic injection molded parts 1, 2, which are in between limit a cavity 3 for the water to be heated.
- the water heater could also be a so-called small storage tank, a water heater or part of a dishwasher, in which case the heating module could be modified accordingly.
- At least one tubular heating element K1, K2 is installed in the cavity 3 in a desired position and is secured in position, for example, by way of its connecting ends 6 which are led out through passages D.
- the passages D are formed, for example, as pipe lugs 11 in the upper side of the molded part 1 of the heating module H. 1 and 2, two pairs of passages D are provided for the connection ends 6 of two tubular heating elements K1, K2. If necessary, more than two pairs or only one pair of passages could also be provided.
- connection ends 6 extend through the passages D so far out that an outer jacket 4 and a connection contact 5 are exposed.
- a grounding and holding clamp E is clamped, which has resilient holding claws 8 as a boundary of an inner opening 7 for positive and non-positive fixing.
- Each clamp E is pushed so far onto the outer jacket 4 that it secures the connection end 6 in the passage D and is supported, for example via an intermediate part 16 (for example a molded plastic part) on the mouth of the pipe socket 11.
- the two clamps E on the connection ends 6 of a tubular heater K1, K2 are connected to one another in an electrically conductive manner, preferably via a connecting web 10 into a one-piece multiple clamp ES (for example a sheet metal stamped and bent part) which has at least one contact tab 9.
- the multiple clamp ES is designed here so that it is adapted to different heights of the two pairs of pipe extensions 11. In this case, a single contact lug 9 may be sufficient for grounding.
- Each intermediate part 16 can be an integral ring. However, the two intermediate parts 16 for a tubular heating element K1, K2 are expediently combined to form an integral structure with the shape of an eight.
- connection ends 6 are connected to the further areas of the tubular heating element in the cavity 3 via a bend 13.
- at least one stop 12 is formed in the cavity 3, preferably adjacent to the passages D, for example a transverse rib which engages in the bend of the bend 13 when the tubular heating element has its desired position.
- Each passage D has an outwardly opening extension 14, into which an annular seal 17 is inserted from the outside, which is secured via the intermediate part 16 on which the clamp E is supported.
- the intermediate part 16 could be omitted, so that the clamp E acts directly on the ring seal 17.
- ring seals 17, e.g. O-rings inserted into the two extensions 14 of the passages D.
- the extensions 14 have openings 15 which (FIG. 1) define an eight.
- the intermediate parts 16 for the two connection ends 6 are combined in a one-piece structure which has the shape of an eight and is seated on the mouths 15 with two annular grooves 18 which are cut with one another.
- pressure collars 19 are formed, which can act on the ring seals 17 from above or lie opposite them at a distance (as shown).
- two separate intermediate parts 16 can be provided.
- the two ring seals 17 and the O-ring could form a one-piece structure. be connected to each other. Then the structure of the orifices 15 in the middle area would have to be excluded.
- the clamp E on the two connection ends 6 presses against the intermediate part 16 from above and keeps it in contact with the orifices 15.
- the 16 secures the ring seals 17. From the interaction between the passages D, the stop 12, and the outside the heating module H supported clamp E results in securing the tubular heater K1 against movement in all directions.
- the clamp E is positively and non-positively fixed on a projection 20 of the heating module H in the mouth region of the passage D in and against the lifting direction or insertion direction of the connection end 6. Due to the claw engagement between the clamp E and the connection end 6 of the tubular heater K1, in cooperation with the passage D, the tubular heater K1 is securely positioned and positioned in all directions.
- the securing protrusion 20 has, for example, engagement recesses 21, e.g. an annular groove, into which gripping projections 22 of the clamp E are snapped, expediently under prestress. Since the clamp E (this could also be a multiple clamp ES as in FIG. 3) is positively locked at at least two spaced-apart locations with respect to the passage, the clamp E, if the connection end 6 emerges from the passage D to the outside want to hike, do not take off on one side.
