Uppfinningen beskrivs närmare nedan under hänvisning till bifogade ritningar.The invention is described in more detail below with reference to the accompanying drawings.
Där visar fig_l en frontvy av en elspis med sin övre del försedd med en indikeríngs- och manöverpanel, §ig_§ ett snitt genom indikerings- och manöverpanelen enligt fig 1 med belys- ningsanordning, samt §ig_§ och fig_í två olika utformade ljus- ledare som separata detaljer i perspektivvy.Fig. 1 shows a front view of an electric stove with its upper part provided with an indication and control panel, §ig_§ a section through the indication and control panel according to Fig. 1 with lighting device, and §ig_§ and fig_ in two differently designed light guides as separate details in perspective view.
I fig 1 är med 1 en elspis allmänt betecknad, som är utförd som inbyggnadsapparat och är inmonterad under en genomgående arbetsplatta 2. Med 3 är en indikerings- och manöverpanel all- mänt betecknad, som är placerad i det översta området av spísens frontsida och är försedd med en serie índikerings- och manöver- element, såsom vridbara strömställarrattar eller vred 4, av vilka blott ett är visat i inmonterat tillstånd, till de en- skilda vreden 4 hörande indikeringselement S, trycktangenter 6 till ett ej närmare beskrivet spiskopplingsur 7 samt ett indi- keringselement 8 för indikering av drift av den ej visade ugnen till elspisen 1. Såsom framgår av tvärsníttsvyn i fig 2 är vreden 4 vridfast förbundna med transparenta, cirkulära indike- ringsskivor 9, som vid sin periferi uppvisar indíkeringssymboler i form av tal 1 - 9. Varje manöverelement i form av vred 4 hör till en separat kokplatta på en på arbetsplattan 2 vilande spishäll, varvid totalt fyra kokplattor är anordnade. Indike- ringssymbolerna 1 - 9 markerar de olika kopplingssteg resp effektsteg, i vilka de tillhörande kokplattorna drivs. Vid skivperiferin är vidare en indikeríngssymbol i form av talet O anordnad, som markerar fránkopplingsläget för den tillhöran- de kokplattan. Vredet 4 är med en axel 10 vridbart lagrat i ett vridlager 11 och står i funktionsförbindning med en ej närmare beskriven kopplings- och regleranordníng 12 för kok- plattorna.-Vid den visade utföringsformen hör de i fig 1 och 2 till vänster visade fyra manöverorganen till spishällens fyra kokplattor, medan de övriga manöverorganen hör till bakugnen.In Fig. 1, 1 denotes an electric stove, which is designed as a built-in appliance and is mounted under a continuous work plate 2. 3 denotes a display and control panel, generally designated, which is located in the uppermost area of the front of the stove and is provided with a series of indicator and operating elements, such as rotatable switch knobs or knobs 4, only one of which is shown in the assembled condition, indicating elements S belonging to the individual knobs 4, pushbuttons 6 to a stove switch 7 not further described and a indicating element 8 for indicating operation of the oven (not shown) of the electric cooker 1. As can be seen from the cross-sectional view in Fig. 2, the knobs 4 are rotatably connected to transparent, circular indicating discs 9, which at their periphery have indicating symbols in the form of numbers 1 - 9. Each control element in the form of a knob 4 belongs to a separate hob on a hob resting on the worktop 2, a total of four hobs being arranged. The indication symbols 1 - 9 mark the various switching stages and power stages, respectively, in which the associated hobs are operated. At the disc periphery, an indicating symbol in the form of the number 0 is further provided, which marks the disconnection position of the associated hob. The knob 4 is rotatably mounted with a shaft 10 in a rotary bearing 11 and is in functional connection with a coupling and control device 12 for the hobs not further described. In the embodiment shown, the four actuators shown in Figs. 1 and 2 on the left belong to the four hobs of the hob, while the other controls belong to the oven.
Frontsidan på indikerings- och mañöverpanelen 3 bildas av en transparent täckhuv 13, som i fig 1 för tydlighets skull till hälften är bortskuren och har de motsvarande genomföringarna 14 för vredens 4 axlar 10. I området mellan täckhuven 13 och en med 15 betecknad mask är pá axlarna 10 resp axlarnas vrid- lager 11 de skalformigt utförda indikeringsskivorna anbragta. v! V1 40 3 447 039 Omedelbart på masken 15 följer det med spisens frontsida paral- lella avsnittet 16 av en L-formad ljusledare 17, t ex av plexiglas. Det andra, vinkelrätt häremot anordnade avsnittet 18 av ljusledaren 17 förlöper omedelbart invid och parallellt med spísens 1 sídovägg 19. Slutligen är indikerings- och ström- ställarpanelen 3 baktill tillslutna genom en täckplât 20, som uppvisar motsvarande öppningar för genomföringen av manöver- organens strömställaraxlar. Ljusledaren 17 är utförd i listform, dvs består av ett platt, skivliknande material. Såsom antyds på ett ställe i fig 1 är utmed de motstående längskanterna av ljusledaren 17 urtag 21 anordnade, i vilka böjflikar 22 på masken 15 ingriper, varigenom ljusledaren 17 blir fixerad till sitt läge. Omedelbart ovanför manöverorganen_har masken 15 kvadratiska urtag 23 och under dessa liggande urtag 24 i form av cirkelringsavsnitt. Den övriga ytan hos masken 15 är ogenom- skinlig, såsom antyds genom längsstreckningen i fig 1. I nivå med uttagen 23 är punkt- eller ringformiga, ljusreflekterande, exempelvis vita indikeríngssymboler 5 tryckta på baksidan av ljusledaren 17, varvid i varje urtag 23 fyra indíkerings- symboler är anordnade, av vilka vart och ett är utfyllt, som markerar läget för den tillhörande kokplattan. Utskärníngarna 24 är anordnade i nivå med indikeringsskivornas 9 periferi, varvid i varje kopplingsläge hos manöverorganet en indikerings- symbol när fram till denna utskärning 24 och där blir synlig.The front side of the indicator and control panel 3 is formed by a transparent cover hood 13, which in Fig. 1 is cut off in half for the sake of clarity and has the corresponding bushings 14 for the shafts 4 of the knobs 4. In the area between the cover hood 13 and a mask designated 15 is the shafts 10 and the pivot bearings 11 of the shafts, respectively, the shell-shaped indicating discs are arranged. v! V1 40 3 447 039 Immediately on the mask 15, it follows with the front side of the stove parallel section 16 of an L-shaped light guide 17, for example of plexiglass. The second, perpendicularly arranged section 18 of the light guide 17 extends immediately next to and parallel to the side wall 19 of the stove 1. Finally, the indicator and switch panel 3 are closed at the rear by a cover plate 20, which has corresponding openings for the passage of actuator shafts. The light guide 17 is made in strip form, ie consists of a flat, disc-like material. As indicated at one point in Fig. 1, recesses 21 are arranged along the opposite longitudinal edges of the light guide 17, in which bending tabs 22 on the mask 15 engage, whereby the light guide 17 is fixed to its position. Immediately above the actuators, the mask 15 has square recesses 23 and below these recesses 24 in the form of circular ring sections. The rest of the surface of the mask 15 is opaque, as indicated by the longitudinal line in Fig. 1. At the level of the sockets 23, dot or annular, light-reflecting, for example white indication symbols 5 are printed on the back of the light guide 17, in each recess 23 four indicating - symbols are arranged, each of which is filled in, which marks the position of the associated hob. The cut-outs 24 are arranged at the level of the periphery of the indicating discs 9, whereby in each coupling position of the operating member an indicating symbol reaches up to this cut-out 24 and becomes visible there.
I frankopplingsläget täcks utskärningen 24 av en mörkfärgad skivsektor 26 på indikeringsskivan 9, varvid symbolen i denna skivsektor är så beskaffad, att den även vid frankopplad spis resp vid frankopplad belysníngsanordning fortfarande är synlig.In the disconnected position, the cut-out 24 is covered by a dark-colored disc sector 26 on the indicator disc 9, the symbol in this disc sector being so shaped that it is still visible even with the disconnected stove or with the disconnected lighting device.
Såsom visas i fig 1 sträcker sig avsnittet 16 av ljusledaren 17, vilken vid den visade utföringsformen är förskjuten uppåt relativt avsnittet 18, över området för utskärningen 24, var- vid återigen reflexionsytor liknande de påtryckta indikerings- elementen 5 är anordnade på ljusledarens 17 baksida i nivå med utskärningarna 24. Den fria änden av ljusledarens 17 av- snitt 18 inmynnar i en ljuslåda Z7, som är anbragt i området för elspisens 1 sidovägg 19 i riktning mot spísens baksida.As shown in Fig. 1, section 16 of the light guide 17, which in the embodiment shown is offset relative to section 18, extends over the area of the cut-out 24, again reflecting surfaces similar to the printed indicating elements 5 being arranged on the back of the light guide 17 in level with the cut-outs 24. The free end of the section 18 of the light guide 17 opens into a light box Z7, which is arranged in the area of the side wall 19 of the electric stove 1 in the direction of the back of the stove.
Ljusladan 27 har en avtagbar låddel 28, vid vilken en lamp- fattning 29 för en glödlampa 30 är fäst. Ljuslàdan 27 har en tr»rr5ormigt förlängd del 31, i vars fria ände 32 den fria änden av ljusledaren 17 inmynnar, såsom visas i fig 2. I det POOR g QUALITY '_11 G J; 447039 konkava hörnomrádet av ljusledaren 17 är en reflexionsbelägg- ning 32 anordnad, exempelvis påtryckt, vilken sörjer för att de från ljuskällan 30 utgående ljusstrålarna förlustfritt går från ljusledaravsnittet 18 in i ljusledaravsnittet 16. Vid driften av elspisen inkopplas ljuskällan 30, varvid det i ljus- ledaren 17 framledda ljuset reflekteras vid reflexionsytorna i nivå med utskärningarna 24 och vid indikeringselementen 5 resp indikeringssymbolerna samt kastas i riktning mot spisfrontsidan genom utskärníngarna i masken 15. Självfallet förhåller det sig så även med de indikerings- och manöverelement, som hör till hakugnen.The light barn 27 has a removable drawer part 28, to which a lamp socket 29 for a light bulb 30 is attached. The light box 27 has a tubularly elongated portion 31, in whose free end 32 the free end of the light guide 17 opens, as shown in Fig. 2. In the POOR g QUALITY '_11 G J; 447039 concave corner area of the light guide 17, a reflection coating 32 is provided, for example applied, which ensures that the light beams emanating from the light source 30 pass without loss from the light guide section 18 into the light guide section 16. During operation of the electric stove, the light source 30 is connected. the light produced by the conductor 17 is reflected at the reflection surfaces at the level of the cut-outs 24 and at the indicating elements 5 and the indicating symbols, respectively, and thrown in the direction of the stove front through the cut-outs in the mask 15. This is also the case with the indicating and operating elements.
I fig 3 och 4 visas ljusledare 17' resp 17", som kan an- vändas i stället för den tidigare beskrivna ljusledaren 17.Figures 3 and 4 show light guides 17 'and 17 ", respectively, which can be used instead of the previously described light guide 17.
Vid utföringsformen enligt fig 3 är ljusledaren 17' likaså L-formigt utförd och har ett till ljuslådan 27 enligt fíg 1 ledande avsnitt 18' samt ett i huvudsak vinkelrätt mot detta anordnat avsnitt 16', som förlöper parallellt och längs med indikerings- och manöverpanelen. För erhållande av så god ljus- upptagning som möjligt är avsnittet 18' utfört avsevärt bredare än avsnittet 16', på vilket indíkeríngssymbolerna och liknande är tryckta. Vidare uppvisar avsnittet 18' vid den direkt i ljus- lâdnn 27 inmynnande änden ett avsnitt 18'", som består av ett material med hög temperaturbållfasthet och som exempelvis genom klistring, svetsning eller pásprutning kan vara förbundet med den övriga delen av ljusledaren 16'. Härigenom säkerställs att någon inskränkning ej sker av ljusledaregenskaperna, speciellt formen på ljusledaren, genom de relativt höga temperaturerna i ljuslådan. Vid utföríngsformen enligt fig 4 är såväl ändytan 35 på den fria änden av ljusledaren 17" som den undre begräns- ningsytan 36 på det smalare avsnittet av ljusledaren försedda med en ljnsrcflekterande beläggning, som i fíg 4 är antydd genom streckning. Pâ detta sätt uppnås maximalt ljusutbyte, dvs full utnyttjníng av det ínstrâlade ljuset.In the embodiment according to Fig. 3, the light guide 17 'is also L-shaped and has a section 18' leading to the light box 27 according to Fig. 1 and a section 16 'arranged substantially perpendicular thereto, which runs parallel and along the indication and control panel. In order to obtain as good light absorption as possible, section 18 'is made considerably wider than section 16', on which the indication symbols and the like are printed. Furthermore, the section 18 'has at the end directly into the light box 27 a section 18' ", which consists of a material with high temperature strength and which, for example by gluing, welding or spraying, can be connected to the rest of the light guide 16 '. This ensures that there is no restriction of the light guide properties, especially the shape of the light guide, by the relatively high temperatures in the light box. In the embodiment according to Fig. 4, both the end surface 35 on the free end of the light guide 17 "and the lower limiting surface 36 on the narrower the section of the light guide provided with a light-reflecting coating, which in Fig. 4 is indicated by a line. In this way, maximum light output is achieved, ie full utilization of the irradiated light.
