Definitions
- a conventional hotplate design (DE-B-26 51 848 corresponding to AU-A-512 394) has a connection plate protruding to the side on a lower cover, at the end of which connection means, for example an insulating body with screw connections, are attached.
- connection means for example an insulating body with screw connections
- a passage means in the form of an insulating body with passage openings for the connecting lines protrudes through an opening in the cover and the connecting plate, which are connected to one another in the opening area by flaps, which is supported on the underside of the hotplate and is thereby fixed. It has also become known in this way to define other functional components which penetrate through the cover, that is to say passage means, for example temperature limiters (EP-B-45 007 corresponding to US-A-43 86 263).
- a passage means was also determined directly on the inside without any support a cover without a connecting plate provided thereon by lugs engaging in recesses on the cover plate (DE-A-36 29 549 corresponding to US-A-48 08 797). There are also passage means which are held in position only by the connecting lines which protrude through them (DE-A-26 20 004 corresponding to US-A-41 22 330).
- the task of the invention is to simplify the assembly of an electric hotplate. It is solved by claim 1.
- the passage means is positively locked between the two due to the connection of the cover and the connecting plate. This is done by alternately up and down support shoulders on projections of the passage means, which practically lock in one plane.
- This version is also particularly simple to carry out in ceramic material, for example steatite, and only requires differently shaped through openings through the cover and connecting plate in order to carry out the locking automatically, without expressions etc. being necessary for this purpose.
- the cover, end plate and passage means can be combined to form a coherent assembly module before they are attached to the hotplate. If the passage means contain lead-throughs for the connecting lines, this assembly need only be slipped onto the reversing hotplate in such a way that the connecting lines penetrate through the openings. Threading of the individual parts and subsequent connection is avoided.
- the passage means can be mounted from any side, preferably fully automatically.
- the connection of the cover and the connecting plate, which at the same time defines the passage means can be done by folding sheet metal tabs in the edge region of the openings or also by riveting at another location, preferably by riveting free of foreign matter.
- Fig. 1 shows an electric hotplate 11 with a hotplate body 12 and a cooking surface 13 located in the use position.
- the lower one in the use position, in the drawings each upper side of the hotplate is closed by a cover 14 made of a profiled sheet metal stamping, which is supported by an outer edge 15 within a cast rim 16 on the underside of the hotplate, ie the heating is embedded.
- the fixing takes place via a screwed-in center bolt 17, via which the hotplate is also attached to a hob or a stove, by means of a nut 18.
- the cover plate can be designed differently, for example, it can also rest on the edge 16 or be fixed in the center by other fastening means.
- connection means 22 in the form of an insulating piece is attached, which contains, for example, screw terminals, with which massive hotplate connecting lines 23 can be connected to power supply lines 24 at a location that is somewhat outside the high temperature range.
- the connection means can contain any connection devices, such as plug-in connections etc., and / or also accommodate temperature sensors etc., which are connected to the hotplate or its feed lines.
- the connecting lines 23 protrude through a lead-through means 25, which is formed as a body from a heat-resistant insulating material, for example steatite or other ceramic materials. It protrudes through openings 26, 27 in cover 14 and connecting plate 20 and is thereby fixed (FIG. 9).
- a lead-through means 25 which is formed as a body from a heat-resistant insulating material, for example steatite or other ceramic materials. It protrudes through openings 26, 27 in cover 14 and connecting plate 20 and is thereby fixed (FIG. 9).
- the opening 26 in the cover 14 has the shape of an elongated hole, which has a widening cutout 28 on each of its two longitudinal sides.
- the opening 27 in the connecting plate 20 has an elongated rectangular shape with rounded corners of greater width than the elongated hole dimensions of the opening 26 in the edge region and projecting sections 29 in the longitudinal central region, so that the opening 27 there is narrower than the opening 26 in the region of the cutouts 28
- the shape of the passage means 25 can be seen from Figures 3 and 5 to 7. It is a relatively narrow body in which four round through openings 30 are provided in series, which expand in a funnel shape at the bottom and have insertion bevels.
- a slight depression 37 of the long sides 34 is provided in the height region of the protrusions 33 after the protrusion 35.
- the shape of the passage means can also be seen from the cuts made in different planes (FIGS. 6 and 7).
- the shape of the connecting plate 20 in the region of the openings can be seen from FIG. 4. It is widened slightly trapezoidal in the opening area and, in addition to the stiffening bends, has 21 stiffening beads 38.
- the shape of the openings 26, 27 in cooperation with that of the lead-through means 25 is selected so that the following assembly method is possible: the pass-through means 25 can be inserted into the opening 26 from above.
- the lower part of the body 39 of the passage means and the projections 35 on both sides run through the opening 26 (that is to say the section shown in cross section in FIG. 7) until the narrow-side edge regions 40 of the opening 26 abut the support shoulders 33.
- the connecting plate 20 is placed over the bushing from above, which is possible since it is cut out correspondingly large in the area of the projections 32. However, it is supported with its projecting sections 29 on the support shoulder 36 of the projection 35, so that support is now provided on one of each of the two sheet metal parts 14, 20 in opposite directions, specifically because of the opposing support shoulders 33 and 36.
- connection plate are connected to one another by rivet points 42.
- rivet points 42 These could be conventional rivets or rags punched out of one material and bent behind the other, but advantageously a rivet connection technique is used which is known under the trademark "TOX”.
- a special rivet and patrix design forms a rivet point in the two superimposed materials, the cross section of which is shown in FIG. 8. The result is two corresponding, merging forms, which also connect to one another in a form-fitting manner due to the lateral flow of material.
- Fig. 4 three of these rivet points can be seen, which are arranged on both sides of the openings 26, 27 and have a large base width for good fixing.
- the passage means 25 is also fixed in a positive manner in both directions.
- the passage means could also be installed from below in the same way as the rest. Otherwise, the means of passage could be designed differently. It is important that there are two areas on it with opposing support shoulders, with insertion in each case in the direction of insertion (direction of the central axis 43 of the passage means) up to the support shoulder 33, 36.
- the further assembly is then very simple.
- the assembly unit consisting of cover 14, connecting plate 20 and penetration means 25 enclosed and fixed by them can be supplied as a whole to the electric hotplate are and, if necessary, automatically threaded over the then still high connecting lines 23, which are only bent afterwards.
- This attachment is also particularly suitable for arrangements in which the connecting lines 23 protrude only slightly from the passage means 25 and are connected there, for example by welding, to laterally running connecting lines.
- connection cover / connecting plate is made by sheet metal tabs 44, which consist of material that protrudes into the opening 27 and has been left standing.
- the same shape of the passage means 25 can be used.
- a total of two sheet-metal tabs 44 are carried out, whereby they would stand vertically downwards in the assembled state in FIG. 11 and then be folded over into the shape shown.
- This connection technology also does not require any foreign materials. It would also be possible to provide the tabs on the cover 14 so that they would then be bent over on the top in the drawings.
- Figures 13 and 14 show that the attachment of the passage means is variable in size.
- a passage means 25a according to FIG. 14 which has only two passage holes 30 and is correspondingly considerably shorter, one can still use the cover plate, which is also provided for the version with four passage holes and accordingly has an opening 26 according to FIG. 2.
- the cover plate which is also provided for the version with four passage holes and accordingly has an opening 26 according to FIG. 2.
- the flange 32 lies on the surface.
- the connecting plate 20 has a cutout 27a (FIG. 13) which is adapted in shape and size to the passage means 25a according to FIG. 14.
- the length of the projections 29 is irrelevant here, because when the connecting plate 20 is plugged in, the guidance is carried out over the outer edges of the flange 32.
- this fastening method is very variable and enables the installation of a wide variety of means of passage in the same cover plate. This reduces the necessary variety of types.
- the guidance in the cover or connection plate therefore does not necessarily have to be taken over by the external shape of the passage means, but can also fall back on internal guidance means, such as the edges 50, 51.
- the connecting plate 20 according to FIG. 13 covers the larger opening 26 in the cover 14.
