Definitions
- the present invention relates to an iron according to the preamble of claim 1.
- Such an iron is known in which the iron shoe is cast. An iron soleplate is then attached to the iron shoe.
- the soleplate of the iron can be riveted to the iron shoe, wherein this riveting can take place in particular in a steam outlet hole in the soleplate of the iron.
- weld bolts to the soleplate that penetrate the iron shoe. These bolts can then be caulked with the iron shoe or can also be provided with a thread, in which case the connection between the iron shoe and the soleplate is made by means of a screwed-on nut.
- the iron shoe and soleplate can also be welded, for example by means of a laser beam.
- glue the iron shoe and soleplate by means of an adhesive, for example based on silicone. These types of fastening can also occur in combination.
- the object of the present invention is to improve the fastening of an iron soleplate to an iron shoe.
- the adhesive preferably a silicone-based adhesive
- the adhesive has a certain elasticity even in the dried or hardened state. Because the distance between the iron shoe and the soleplate has different values at different points, a connection between the iron shoe and the soleplate with different elasticity is also created at these different points. If this distance is larger, there is also a thicker layer of adhesive between the iron shoe and the soleplate. Because of this thicker adhesive layer and the elasticity of the adhesive, the connection of the iron shoe and soleplate has greater elasticity at these points than at the points where the adhesive layer is thinner. Thus, by correctly arranging these different distances between the iron shoe and soleplate, it is possible that the iron shoe and soleplate can work against one another when heated, without the durability of the adhesive connection of the iron shoe and soleplate being endangered. This has a particularly advantageous effect when the soleplate of the iron has a bimetal effect when heated and / or a different coefficient of thermal expansion than the iron shoe.
- the different distances are so dimensioned that at the points where there is a greater distance between the soleplate and the iron shoe due to a bimetallic effect of the iron sole, the distance between the iron shoe and the soleplate is greater even in the unheated state.
- the distance between the iron shoe and the soleplate of the iron expediently has greater values at those points where, due to the different coefficients of thermal expansion, a larger value occurs when heated Displacement results.
- an iron according to claim 2 enables a flexible connection of the iron shoe and soleplate, which increases in flexibility with an increasing distance from a line.
- the distances transversely to the lines at which the respective distances between the iron shoe and the soleplate are set can have different values. For example, it is possible to provide a certain distance between the iron shoe and the soleplate along the outer edges of the iron. At the tip of the iron there is then a certain distance at a shorter distance across the line in the longitudinal direction of the iron than at the rear end of the iron. Correspondingly, there is a greater distance across a line in the transverse direction of the iron in the middle of this line, at which the certain distance between the iron shoe and the sole of the iron is reached than near the points at which this line intersects the outer edges of the iron.
- the configuration of the iron according to claim 6 enables the additional mechanical fastening a particularly secure fastening of the iron shoe and soleplate.
- a punctiform attachment or with a locally limited attachment it can advantageously be achieved that the iron shoe and soleplate are floatingly mounted in the vicinity of this mechanical attachment, so that no or only slight mechanical stresses occur.
- the embodiment according to claim 7 enables a comparatively simple concept of the iron by assigning a certain distance between the iron shoe and the soleplate of the iron to extensive areas.
- the individual points can be assigned specific distances.
- the iron according to claim 1 1 shows in an advantageous manner that on the outer sides of the ironing surface a greater distance between the iron shoe and soleplate is achieved than in the inner region of the ironing surface.
- the separation of these two areas by the steam distribution channel makes the iron particularly easy to manufacture.
- no mechanical stresses can occur at the transition between these areas of different elasticity of the connection of the iron shoe and soleplate, since the steam distribution channel forms the transition. In the area of this steam distribution channel there is no connection at all between the iron shoe and the soleplate.
- the design of the iron according to claim 1 2 ensures that there is also good heat transfer between the iron shoe and the soleplate in the outer area of the ironing surface.
- Fig. 2 a second embodiment of an iron
- Fig. 3 a third embodiment of an iron.
- Fig. 1 shows a vertical section in the longitudinal direction through an iron. According to the 1, an iron shoe 101 has a convex underside
- An iron soleplate 103 is connected to this iron shoe 101 by means of an adhesive layer 104.
- a heater 105 is poured into the iron shoe 101, by means of which the iron shoe 101 is heated. The heat is emitted from the iron shoe 101 to an iron sole 103, the underside 106 of which forms the ironing surface.
- the underside 106 can be coated. In the exemplary embodiment in FIG. 1, the coating on the underside 106 has a smaller coefficient of thermal expansion than the material of the soleplate 103.
- FIG. 1 03 a concave deflection of the soleplate 103.
- this is shown by the dash-dotted representation of the soleplate 103 in the heated state.
- iron shoe 101 and soleplate 103 are at the greatest distance due to the deflection. Even before the iron soleplate 103 deflected when heated, the distance between the iron shoe 101 and the iron soleplate 103 was greatest in these two areas. Because the adhesive layer 104 is thickest in the front and rear region 107, 108 of the iron in the non-heated state, the greatest elasticity of the adhesive layer 104 results precisely in these regions 107, 108.
- the deflection of the soleplate 103 is therefore due to the Bimetal effect prevented only to a lesser extent than would be the case with an adhesive layer 104 with a constant thickness. Overall, the adhesive layer 104 is therefore subjected to less mechanical stress, which leads to a longer durability of the adhesive layer 104.
- FIG. 1 also shows that the point at which the adhesive layer 104 is thinnest is offset in the longitudinal direction of the iron, viewed from the center, in the direction of the rear end 108 of the iron. As a result, this point is arranged approximately in the vicinity of the center of gravity of the ironing surface.
- Fig. 2 also shows a vertical section in the longitudinal direction through an iron.
- the iron shoe 201 in the illustration in FIG. 2 does not have a convexly curved underside. Rather, in the iron according to the illustration in FIG.
- first area 202 in which the iron shoe 201 and the iron sole 203 are at a certain first distance and a second area 205 in which the iron shoe 201 and the iron sole 203 have a certain second distance Have a distance that is greater than the determined first distance.
- the first region 202 advantageously extends over the center of gravity of the ironing surface.
- An iron soleplate 203 is connected to this iron shoe 201 by means of an adhesive layer 204.
- a heater 207 is cast into the iron shoe 201, by means of which the iron shoe 201 is heated.
- the heat is emitted from the iron shoe 201 to an iron soleplate 203, the underside of which forms the ironing surface.
- the underside can be coated. In the exemplary embodiment in FIG. 2, the coating on the underside has a smaller coefficient of thermal expansion than the material of the soleplate 203.
- Coefficient of thermal expansion of the coating of the underside of the iron soleplate 203 a concave deflection of the iron soleplate 203.
- this is shown by the dash-dotted representation of the iron soleplate 203 in the heated state.
- iron shoe 201 and iron soleplate 203 have the greatest distance due to the deflection. Even before the iron soleplate 203 deflected when heated, the distance between the iron shoe 201 and the iron soleplate 203 was greatest in these two areas. Because the adhesive layer 204 is thickest in the front and rear area of the iron when not heated, the greatest elasticity of the adhesive layer 204 results in these areas in particular.
- the deflection of the iron soleplate 203 is only prevented to a lesser extent due to the bimetal effect than is the case with a constant thickness adhesive layer 204 would.
- the adhesive layer 204 is therefore subjected to less mechanical stress, which leads to a longer durability of the adhesive layer 204.
- the slight beveling of the edges during the transition from the first region 202 to the region 205 means that the iron shoe 201 can be manufactured more easily by means of a casting mold.
- the bevel of these edges in the transition area is approx. 10 ° to the vertical.
- Fig. 3 shows a vertical section transverse to the longitudinal direction through an iron.
- the underside of the iron shoe 301 is shaped such that regions 304, 305, in which there is an adhesive layer between the iron shoe 301 and the iron sole 303, each have a different distance between the iron shoe 301 and the iron sole 303.
- this connection is produced by laser welding.
- Iron shoe 301 and soleplate 303 are pressed against each other.
- a laser beam is directed onto the iron shoe 301 from above.
- This laser is advantageously an NdYAG laser.
- the iron shoe 301 then melts in the area in which the laser beam strikes there.
- the material on the upper surface of the iron sole 303 is melted.
- the iron shoe 301 and the iron sole 303 therefore melt into one another at this point.
- the area 307 surrounds this laser welding connection point 308. This avoids that adhesive has a disruptive effect on the weld connection.
- the area 307 is adjoined by an area 304 in which there is an adhesive layer between the iron shoe 301 and the iron sole 303.
- a receiving channel 309 for the adhesive At the transition from Area 304 to area 307 is a receiving channel 309 for the adhesive.
- an area 306 adjoins the area 304, in which the iron shoe 301 and the iron sole 303 touch directly.
- Adhesive that contains silicone and has comparatively good heat transfer properties is indeed used as the adhesive. However, this heat transfer is worse than the heat transfer at the places where there is an iron shoe
- this area 306 has the effect that a convex deflection of the iron sole 303 when it is attached to the iron shoe 301 is largely prevented. Because of the elasticity of the adhesive layer, the iron shoe 303 would lack the abutment if it were not supported in the area 306.
- area 306 is followed by a circumferential steam outlet channel 302.
- This steam outlet channel 302 is connected to an evaporator chamber (not shown). After the water in this evaporator chamber has been evaporated, it enters the steam outlet channel 302.
- the soleplate 303 (not shown) has holes through which the steam can exit onto the material to be ironed.
- the steam outlet duct joins in the direction of the outer edge of the ironing surface
- the adhesive layer in the area 305 has a greater thickness than the adhesive layer in the area 304.
- the distance between the iron shoe and the soleplate in the area which is filled with adhesive and in which this distance is the smallest is approximately 0.1-0.2 mm, in particular 0.15 mm.
- the distance between the iron shoe and the soleplate in the area which is filled with adhesive and in which this distance is greatest is approximately 0.5-1.0 mm, in particular 0.6-0.8 mm.
