Električni stikalni sklop za varnostno pripravo v stroju bele tehnikeElectrical switch assembly for safety preparation in white goods machine

Predmet izuma je za varnostno pripravo v stroju bele tehnike predvideni električni stikalni sklop, v katerem je med prevesno stikalno pero, na katero je nasajeno zapiralo varnostne priprave, in med bimetalni trak vstavljen PTC-uporovni element (uporovni element s pozitivnim temperaturnim koeficientom) in v katerem je izboljšana izravnava premika PTC-uporovnega elementa s pomočjo bimetalnega traku proti prevesnemu stikalnemu peresu zaradi morebitne visoke temperature stroja.The subject of the invention is a safety switch in a white goods machine provided with an electrical switch assembly in which a PTC-resistive element (a positive element with a positive temperature coefficient) is inserted between the overhanging switch to which the safety devices are seated and the bimetallic strip. which improves the offsetting of the movement of the PTC resistor element by means of a bimetallic strap against the oversized switch pen due to the possible high temperature of the machine.

Izum je po mednarodni klasifikaciji patentov uvrščen v razred D 06F 37/42.The invention is classified in Class D 06F 37/42 according to the International Patent Classification.

Naloga izuma je, izboljšati zaznavanje temperature stroja s kompenzirnim bimetalnim trakom, tako da se s primerno namestitvijo le-tega glede na bimetalni trak zmanjša vpliv temperature PTC-uporovnega elementa, ki ga nosi bimetalni trak.It is an object of the invention to improve the sensing of the temperature of the machine with a compensating bimetallic strip so that by properly positioning it relative to the bimetallic strip, the influence of the temperature of the PTC resistive element carried by the bimetallic strip is reduced.

Prijaviteljica izdeluje varnostno pripravo v stroju bele tehnike z ustreznim električnim stikalnim sklopom. Le-ta obsega PTC-uporovni element, na prvo električno priključno sponko priključen bimetalni trak, kompenziral bimetalni trak in na drugo električno priključno sponko priključeno prevesno stikalno pero. Le-to sestavljata trakasto pero in locnasto pero, ki sta na enem koncu medsebojno togo speti in pritrjeni na okrov električnega stikalnega sklopa, blizu prostemu koncu pa sta prožno speti s sklopilnim peresom. PTC-uporovni element je vstavljen med bimetalni trak in trakasto pero, katerega položaj odloča o preskoku locnastega peresa iz ene v drugo stabilno lego, in je z njima v električnem stiku. Na prostem koncu locnastega peresa je nagibno nasajeno zapiralo varnostne priprave. Konca bimetalnega traku sta oprta na konca ob njem nameščenega kompenzirnega bimetalnega traku, ki izravna premik PTC-uporovnega elementa zaradi povišane temperature stroja. Bližina kompenzirnega bimetalnega traku do PTC-uporovnega elementa in njegov dober toplotni stik preko obeh koncev bimetalnega traku sta razlog, da je kompenzirat bimetalni trak premočno pod vplivom temperature PTCuporovnega elementa, s čimer je zasenčen vpliv temperature stroja.The applicant manufactures a safety device in a white goods machine with a suitable electrical switch assembly. It comprises a PTC resistor element, a bi-metal strip connected to the first electrical terminal, compensated for a bi-metal strip, and an oversized switch pen connected to the second electrical terminal. They consist of a ribbon pen and an arcuate pen, which are rigidly fastened at one end and fastened to the housing of the electrical switch assembly, and are flexibly fastened to the free end by a coupling pen. The PTC resistor element is inserted between the bimetallic strip and the ribbon pen, the position of which decides to leap the pencil from one stable position to another and is in electrical contact with them. At the free end of the bow pen, the tilt bar closed the safety devices. The ends of the bimetallic strip are supported by the compensating bimetallic strip adjacent to it, which compensates for the movement of the PTC resistor element due to the increased temperature of the machine. The proximity of the compensating bimetallic strip to the PTC resistor element and its good thermal contact across the two ends of the bimetallic strip are the reason that the bimetallic strip compensates for being strongly influenced by the temperature of the PTC resistor element, thereby obscuring the influence of the machine temperature.

Navedena naloga je rešena z električnim stikalnim sklopom za varnostno pripravo v stroju bele tehnike, obsegajočim PTC-uporovni element, na prvo električno priključno sponko priključen bimetalni trak, kompenzirat bimetalni trak in na drugo električno priključno sponko priključeno prevesno stikalno pero, na katero je nasajeno zapiralo varnostne priprave in med katerega o njegovem preskoku odločujoči del in med bimetalni trak je v električnem stiku z obema vstavljen PTC-uporovni element, pri čemer je električni stikalni sklop po izumu značilen po tem, da je prvi konec bimetalnega traku oprt na regulirni vijak, drugi konec pa na kompenzirni bimetalni trak.The said problem is solved by an electrical switch assembly for the safety device in a white goods machine comprising a PTC resistive element, a bi-metal strip connected to the first electrical terminal, compensate for a bi-metal strip, and a hanging switch to which a lock is attached to the second electrical terminal. of the safety device and between which the decisive part and between the bimetallic strip is in electrical contact with both is inserted a PTC resistor element, wherein the electrical switch assembly of the invention is characterized in that the first end of the bimetallic strip is supported by a control screw, the second and the end to the compensating bimetallic strip.

Prednostni izvedbeni primer električnega stikalnega sklopa po izumu je značilen po tem, da je PTC-uporovni element nameščen na sredini bimetalnega traku in da je drugi konec bimetalnega traku oprt na sredino na obeh koncih podprtega kompenzirnega bimetalnega traku.A preferred embodiment of the electrical switch assembly according to the invention is characterized in that the PTC resistor element is arranged in the middle of the bimetallic strip and that the other end of the bimetallic strip is centered at both ends of the supported compensating bimetallic strip.

Posebno prednostni izvedbeni primer električnega stikalnega sklopa po izumu je značilen po tem, da dolžina bimetalnega traku presega premer PTC-uporovnega elementa za toliko, da PTC-uporovni element le malo vpliva na temperaturo kompenzirnega bimetalnega traku.A particularly preferred embodiment of the electrical switch assembly of the invention is characterized in that the length of the bimetallic strip exceeds the diameter of the PTC resistor element in such a way that the temperature of the compensating bimetallic strip is little affected by the PTC resistor element.

Za varnostno pripravo v stroju bele tehnike predvideni električni stikalni sklop po izumu ima prednost glede na znani električni stikalni sklop v tem, da je v njem verneje izvedena izravnava zaradi povišane temperature stroja, kar dobro vpliva na krajši čas izklopa varnostne priprave, pa tudi nihanje izklopnih časov je manjše.For the safety appliance of the household appliances, the electrical switchgear according to the invention has the advantage over the known electric switchboard in that it is more likely to compensate for the elevated temperature of the machine, which has a good effect on the shorter switch-off time of the safety appliance, as well as the oscillation of switching offs. there are fewer times.

Izum je v nadaljnjem podrobno obrazložen na osnovi opisa izvedbenih primerov ter pripadajočega načrta, ki na edini sliki v prerezu prikazuje prednostni izvedbeni primer električnega stikalnega sklopa po izumu za varnostno pripravo v stroju bele tehnike.The invention is further explained in detail on the basis of a description of the embodiments and the accompanying plan, which in the cross-sectional view shows a preferred embodiment of an electrical switch assembly according to the invention for a safety device in a white goods machine.

Za varnostno pripravo v stroju bele tehnike predvideni električni stikalni sklop po izumu je na sliki prikazan v prerezu. Obsega PTC-uporovni element 1, na prvo električno priključno sponko električnega stikalnega sklopa priključen bimetalni trak 2, kompenzirni bimetalni trak 21 in na drugo električno priključno sponko električnega stikalnega sklopa priključeno prevesno stikalno pero 3.The electrical switch assembly of the invention according to the invention is shown in cross-sectional view for the safety device in the household appliances. It comprises a PTC resistor element 1, a bi-metal strip 2 connected to the first electrical terminal of the electrical switch assembly, a compensating bi-metal strip 21, and an oversized switch pin 3 connected to the second electrical terminal of the electrical switch assembly.

Prevesno stikalno pero 3 sestavljata trakasto pero 31 in locnasto pero 32. Peresi 31 in 32 sta na enem koncu medsebojno togo speti in pritrjeni na okrov električnega stikalnega sklopa, blizu prostemu koncu pa sta prožno speti s sklopilnim peresom 33. Locnasto pero 32 v prevesnem stikalnem peresu 3 se glede na položaj trakastega peresa 31 preveša iz ene v drugo stabilno lego.The oversized switch pen 3 is made up of a strip pen 31 and an arcuate pen 32. The rails 31 and 32 are rigidly fastened at one end and fastened to the housing of the electrical switch assembly, and at the free end are flexibly seated with a coupling pen 33. the pen 3 is reversed from one stable position to another depending on the position of the ribbon pen 31.

PTC-uporovni element 1 je vstavljen med bimetalni trak 2, kije prednostno nameščen na sredini bimetalnega traku 2, in med trakasto pero 31, katerega lega je odločujoča za preskok prevesnega peresa 3. PTC-uporovni element 1 je v električnem stiku z bimetalnim trakom 2 in preko kontakta 311 na trakastem peresu 31 tudi z le-tem.The PTC resistor element 1 is inserted between the bimetallic strip 2, which is preferably located in the middle of the bimetallic strip 2, and between the strip pen 31, the position of which is crucial for the skip of the pens 3. The PTC resistor element 1 is in electrical contact with the bimetallic strip 2 and through pin 311 on the ribbon pen 31 also with it.

Na znan način je zapiralo 4 varnostne priprave nagibno nasajeno na prostem koncu locnastega peresa 32, kije blizu tega konca opremljeno z odmičnim kontaktom 321.In a known manner, the closure 4 of the safety device is inclined at the open end of the arch pen 32, which is provided with a contact contact 321 near that end.

Prvi konec bimetalnega traku 2 je oprt na regulirni vijak 22, drugi konec pa na kompenzirni bimetalni trak 21, in sicer prednostno na sredino na obeh koncih v okrovu električnega stikalnega sklopa oprtega kompenzirnega bimetalnega traku 21.The first end of the bimetallic strip 2 is supported by the adjusting screw 22 and the second end by the compensating bimetallic strip 21, preferably centered at both ends in the housing of the electrical switch assembly of the tightened compensating bimetallic strip 21.

Ko je na električni priključni sponki električnega stikalnega sklopa po izumu priključena električna napetost, teče električni tok skozi PTC-uporovni element, ki se zato segreva. Segreva se tudi bimetalni trak 2, ki je v dotiku s PTC-uporovnim elementom 1, in le-tega potiska proti trakastemu peresu 31. Pri določenem premiku le-tega locnasto pero 32 prevesnega stikalnega peresa 3 preskoči proti svoji drugi stabilni legi in zapiralo 4 se premakne v smeri 41 proti zapornemu položaju.When an electrical voltage is connected to the electrical terminal block of the electrical switch assembly according to the invention, electrical current flows through the PTC resistor element, which is therefore heated. The bimetallic strip 2, which is in contact with the PTC resistor element 1, is also heated, and it is pushed against the ribbon pen 31. At a certain displacement thereof, the ribbed pen 32 of the oversized switch pen 3 jumps to its second stable position and the closure 4 moves in the direction 41 towards the lock position.

Kompenzirni bimetalni trak 21 izravnava omenjeni premik za prispevek, ki je posledica povišane temperature stroja. PTC-uporovni element 1 naj zato le malo vpliva na temperaturo kompenzirnega bimetalnega traku 21. Le-ta mora namreč zaznavati temperaturo stroja, na katerem je nameščena varnostna priprava. To se doseže tako, da dolžina bimetalnega traku 2 dovolj presega premer PTC-uporovnega elementa 1, da segreti PTC-uporovni element 1 ne vpliva premočno na kompenzirni bimetalni trak 21.The compensating bimetallic strip 21 offsets said displacement for the contribution due to the elevated temperature of the machine. The PTC resistor element 1 should therefore only slightly affect the temperature of the compensating bimetallic strip 21. It must detect the temperature of the machine on which the safety device is mounted. This is achieved in such a way that the length of the bimetallic strip 2 sufficiently exceeds the diameter of the PTC resistor element 1 that the compensated bimetallic strip 21 is not significantly affected by the heated PTC resistor element 1.
