Definitions
- the present invention relates to an electrical component comprising an electrically insulating ceramic plate carrying on one of its faces a resistive and / or conductive screen-printed track, the other face of this ceramic plate being in contact with a metal plate intended to be heated or whose temperature you want to measure.
- the invention also relates to a household appliance with steam and in particular a steam iron comprising an electrical component of the above type.
- one of the problems to be solved is to provide a lasting electrical connection and electrical insulation of the electrical component and its connectors in a hot and humid environment, namely at a temperature between 250 and 300 ° C and a humidity level of 100%.
- the above component is most often fixed on the plate whose temperature is to be raised by a layer of adhesive (for example silicone) ensuring mechanical strength and thermal transfer.
- the electrical connection can be made by a combination of studs and bonded wires or by metal contacts maintained under pressure against the resistive and / or conductive tracks.
- Such a construction has the disadvantage that under the combined effects of 2 temperature and steam, the electrical contacts peel off or oxidize; moreover, by condensing on the circuit, the vapor causes priming at different points thereof.
- the object of the present invention is to remedy the above drawbacks.
- the invention thus relates to an electrical component comprising an electrically insulating ceramic plate carrying on one of its faces a resistive and / or conductive screen-printed track, the other face of this ceramic plate being in contact with a metal plate intended to be heated or whose temperature is to be measured, the track comprising at least one metallized end for establishing an electrical connection with a conductive wire.
- this electrical component is characterized in that the conductive wire is welded to said metallized end and in that the ceramic plate is entirely covered by a metal cover whose peripheral edges surround said plate and are fixed in a sealed manner to the metal plate by means of a resin, the side wall of said cover comprising at least one opening for the passage of the conductive wire or wires, the or said openings being closed by a sealing resin.
- said cover has a rectangular shape whose lateral faces have a height greater than the thickness of the ceramic plate so as to leave a space between the track and the upper wall of the cover.
- the conductive wire welded to said metallized end is covered with an adhesive based on epoxy resin.
- the ceramic plate is bonded to the metal plate by means of a layer of adhesive.
- the adhesive layer projects beyond the periphery of the ceramic plate so as to simultaneously bond the peripheral edge of the cover to the metal plate.
- said adhesive layer is thick enough to seal the opening (s) of the conductive wire (s).
- said space located between the upper wall of the cover and the resistive and / or conductive track is filled with a resin, this resin itself ensuring the fixing of the cover on the metal plate and the closure. of the passage opening (s) of the conductor wire (s).
- said metal plate forms part of the sole of a steam iron.
- the invention also relates to a household appliance, in particular a steam iron comprising an electrical component of the above type.
- FIG. 1 is a partial longitudinal sectional view of a soleplate of a steam iron comprising an electrical component according to the invention
- - Figure 2 is an enlarged view of detail A of Figure 1;
- - Figure 3 is a partial plan view of the ceramic plate showing the resistive and / or conductive track and the metallized ends thereof;
- FIG. 4 is a partial plan view showing the electrical connection of the conductive wire on the metallized end of the resistive and / or conductive track. 4
- the electrical component 1 comprises an electrically insulating plate 2 made of ceramic bearing on one of its faces (see FIG. 3) a resistive and / or conductive track 4 screen printed. The other side of this ceramic plate 2 is in contact with a metal plate 3 (see FIG. 1) intended to be heated or whose temperature is to be measured.
- the resistive and / or conductive track 4 has at least one metallized end 5 (two in the example of FIG. 3), to establish an electrical connection with a conductive wire 6.
- the conductive wire 6 is welded to the metallized end 5. Furthermore, the ceramic plate 2 is entirely covered by a metal cover 8 whose peripheral edges 8b surround the plate 2 and are fixed in a sealed manner to the metal plate 3 by means of a resin or glue.
- the side wall 8a of the cover 8 comprises at least one opening 9 (see FIGS. 2 and 4) for the passage of the conductive wire or wires 6, the said opening or openings being closed by a sealing resin.
- the cover 8 has a rectangular shape whose side faces 8a have a height greater than the thickness of the ceramic plate 2, so as to leave a space ê between the resistive and / or conductive screen-printed track 4 and the upper wall of the cover 8.
- the conductive wire 6 welded to the metallized end 5 is covered with an adhesive 10, for example based on epoxy resin.
- the metallized end (s) 5 are metallized by means of a layer of silver.
- the ceramic plate 2 is bonded to the metal plate 3 by means of a layer of adhesive. 5
- the aforementioned adhesive layer projects beyond the periphery of the ceramic plate 2 so as to simultaneously bond the peripheral edges 8b of the cover 8 to the metal plate 3.
- said layer of adhesive is thick enough to seal the opening (s) 9 of the conductor wire (s) 6.
- the space - located between the upper wall of the cover 8 and the resistive and / or conductive track 4 is filled with a resin 11.
- This resin 11 itself provides the fixing of the cover 8 on the metal plate 3 and the obturation of the opening or openings 9 for the passage of the conducting wire or wires 6.
- a layer of resin 11 is present between the peripheral edge 8b of the cover 8 as well as between the ceramic plate 2 and the side faces 8a of the cover 8.
- the resin 11 covers the ceramic plate 2 but does not entirely fill the space e.
- the resin 11 also covers the conductive wire 6 welded to the metal end 5.
- the metal plate 3 is made of aluminum.
- the metal plate 3 is part of the heating soleplate of a steam iron.
- This heating sole is constituted by a molded element 12 of aluminum in which is coated a tubular electrical resistance (not shown) for heating.
- a cavity 13 is formed between the element 12 and the plate 3.
- the electrical component 1 described above fixed to the plate 3 is located in the 6 cavity 13.
- the resistive and / or conductive track 4 screen printed on the ceramic plate 2 can be used to heat a determined area of the cap 3 of the soleplate of the iron. In another application, this resistive and / or conductive track 4 can be used to accurately measure the temperature of the cover 3.
- the cover may have a non-parallelepiped shape.
- the invention finds its application in the technical field of household electrical appliances with steam and in particular steam irons.
