Opfindelsen angår en strygerulle med en strygevalse, hvis omløbshastighed styres af en til måling af fugtindhold indrettet elektronisk måler.BACKGROUND OF THE INVENTION The present invention relates to an ironing roller having an ironing roller whose speed of rotation is controlled by an electronic meter for measuring moisture content.

Der kendes strygeruller af denne art, hvor målerens måle-5 elektroder er anbragt på indersiden af strygerullens varme-vange. Denne placering giver imidlertid anledning til store problemer, da varmevangens overflade er af metal. Det er derfor nødvendigt, at måleelektroderne isoleres elektrisk i forhold til varmevangens metaloverflade.Iron rolls of this kind are known in which the measuring electrodes of the meter are arranged on the inside of the heat rollers of the iron roll. However, this location causes major problems as the surface of the heat sink is made of metal. Therefore, it is necessary that the measuring electrodes are electrically insulated from the metal surface of the heat sink.

10 Derudover er der den ulempe, at måleelektroderne kun kan anbringes på en del af varmevangens overflade. Fugtigheden kan derved kun måles disse steder, hvad der kan føre til mangelfulde måleresultater og dermed til ukorrekt regulering af drivakselens omløbshastighed.In addition, there is the disadvantage that the measuring electrodes can only be placed on a part of the surface of the heat sink. The humidity can only be measured in these places, which can lead to defective measurement results and thus to incorrect control of the drive shaft speed.

15 Formålet med opfindelsen er at tilvejebringe en strygerulle af den indledningsvis nævnte art, som på enkel måde kan måle fugtigheden i samtlige strygeområder, uden at strygerullens drift forstyrres.The object of the invention is to provide an ironing roller of the kind mentioned above, which can easily measure the moisture in all ironing areas without disturbing the operation of the ironing roll.

Dette opnås ifølge opfindelsen, ved at måleren, der har to 20 elektroder, har mindst den ene elektrode anbragt på strygevalsen, og at denne/disse elektrode(r) dækker hele strygevalsens strygeoverflade. Herved opnås, at måleren kan måle fugtigheden i samtlige strygeområder, hvad der åbner mulighed for en optimal afpasning af strygevalsernes 25 omløbshastighed i forhold til den øjeblikkelige fugtighed af det stof, der stryges, samtidig med at elektroderne er enkelt anbragt, da mindst den ene af målerens elektroder er anbragt på strygevalsen.This is achieved according to the invention in that the meter having two electrodes has at least one electrode disposed on the ironing roller and that this electrode (s) covers the entire ironing surface of the ironing roller. Hereby, the meter is able to measure the humidity in all the ironing areas, which allows for an optimal adjustment of the circulation speed of the ironing rollers 25 relative to the instantaneous humidity of the fabric being ironed, while the electrodes are simply disposed, since at least one of the the meter's electrodes are placed on the ironing roller.

Strygevalsen ifølge opfindelsen kan være ejendommelig ved 30 det, der er angivet i krav 2. Denne udformning realiserer på enkel måde strygerullen.The ironing roller according to the invention may be peculiar to what is stated in claim 2. This embodiment easily realizes the ironing roll.

Ifølge opfindelsen kan elektroden på strygevalsen være anbragt under et strygeklæde og være udformet som bånd, som er fastgjort aksialt eller langs omkredsen på strygevalsen, og som via forbindelsesledere er forbundet med slæberingen. Herved 5 undgås, at elektroderne kortsluttes, når der ikke er noget klæde, der skal stryges i strygerullen.According to the invention, the electrode on the ironing roller may be placed under an ironing cloth and be formed as bands which are fixed axially or along the circumference of the ironing roller and which are connected to the towing ring via connecting conductors. This prevents the electrodes from being short-circuited when there is no cloth to be ironed in the ironing roll.

Den udformning af strygerullen ifølge opfindelsen, der er angivet i krav 4, angiver en enkel måde at anbringe elektroden på strygevalsen.The design of the ironing roll according to the invention, set forth in claim 4, provides a simple way of applying the electrode to the ironing roller.

10 Ved det, der er angivet i krav 5, opnås en elektrisk adskillelse mellem den på strygevalsen anbragte elektrode og den elastiske bevikling.10, as claimed in claim 5, an electrical separation is obtained between the electrode arranged on the ironing roller and the elastic winding.

En særlig enkel opbygning af strygerullen ifølge opfindelsen er angivet i krav 6.A particularly simple structure of the ironing roll according to the invention is given in claim 6.

15 Ved den udformning af strygerullen ifølge opfindelsen, der er angivet i krav 7, opnås særligt lave fremstillingsomkostninger .In the design of the ironing roll according to the invention as set forth in claim 7, particularly low manufacturing costs are obtained.

En alternativ udformning af strygerullen ifølge opfindelsen er angivet i krav 8. Herved opnås, at strømvejen mellem 20 elektroderne ikke er frit tilgængelige.An alternative embodiment of the ironing roll according to the invention is set out in claim 8. Hereby, it is achieved that the current path between the 20 electrodes is not freely accessible.

Den udformning af strygerullen ifølge opfindelsen, der er angivet i krav 9, anviser en enkel aftastning af elektroderne i det tilfælde, hvor begge elektroderne er anbragt på strygevalsen.The design of the ironing roll according to the invention, as claimed in claim 9, provides a simple scanning of the electrodes in the case where both the electrodes are arranged on the ironing roller.

25 Krav 10 angiver en strygerulle ifølge opfindelsen, der er særlig billig at fremstille.Claim 10 discloses an ironing roll according to the invention which is particularly inexpensive to manufacture.

Opfindelsen skal forklares nærmere i det følgende under henvisning til tegningen, hvor 3 141361 fig. 1-4 viser strygerullen med hver sin måde at anbringe elektroderne på - set i snit.BRIEF DESCRIPTION OF THE DRAWINGS The invention will be explained in more detail below with reference to the drawing, in which FIG. 1-4 shows the ironing roll, each with its own way of placing the electrodes - cut in section.

Den i figurerne viste strygevalse 1 består af et valselegeme 10, som har en elastisk bevikling 11, hvorpå der er an-5 bragt et strygeklæde 12.The ironing roller 1 shown in the figures consists of a roller body 10 which has an elastic winding 11 on which is placed an ironing cloth 12.

Strygevalsen 1 er fastgjort til en faststående, bærende aksel 2.The ironing roller 1 is attached to a fixed bearing shaft 2.

Til strygevalsen 1 er fastgjort en strygesål 3, der på sin inderside bærer en varmevange 30. Det er ligegyldigt, af 10 hvilken art strygesålen er, og på hvilken måde denne virker.An ironing sole 3 is attached to the ironing roller 1, which carries on its inside a heat sink 30. It does not matter what kind of ironing sole is and how it works.

Strygevalsen 1 drives af en motor 4 via en måler 5, der er indrettet til styring af omløbstallet.The ironing roller 1 is driven by a motor 4 via a meter 5 arranged to control the bypass number.

Strygevalsen 1's omløbstal styres af måleren 5 i afhængig-15 hed af fugtindholdet i det materiale, der stryges. Til måling af fugtindholdet er måleren 5 udstyret med to elektroder, hvoraf mindst den ene er anbragt på strygevalsen 1.The orbital number of the ironing roller 1 is controlled by the meter 5 depending on the moisture content of the material being ironed. For measuring the moisture content, the meter 5 is equipped with two electrodes, at least one of which is arranged on the ironing roller 1.

Den/de elektrode(r), der er anbragt på strygevalsen 1, dækker hele strygevalsens strygeoverflade, som det er 20 vist i fig. 1-4, der viser forskellige elektrodeanbringelser. Den elektriske modstand mellem de to elektroder ændres i afhængighed af rullevasketøjets fugtighed. Med udtrykket "dækker hele strygevalsens strygeoverflade" menes "dækker ethvert punkt af strygevalsens strygeoverflade" eller "dækker 25 hele strygevalsens strygeoverflade f.eks. som et fintmasket net, således at fugtindholdet overalt i strygematerialet kan influere på den elektriske modstand mellem målerens elektroder". Denne modstand styrer via måleren 5 strygevalsens 1 omløbshastighed, således at ved tiltagende fugt 30 nedsættes strygevalsens omløbstal. Tøjet, der skal stryges, forbliver derved i længere tid i strygeområdet, således at der opnås et optimalt strygeresultat. Ved delvis 141341 4 tørt eller helt tørt vasketøj opnås højere rullehastighed.The electrode (s) disposed on the ironing roller 1 covers the entire ironing surface of the ironing roller, as shown in FIG. 1-4 showing various electrode positions. The electrical resistance between the two electrodes changes depending on the humidity of the roller laundry. By the term "covers the entire ironing surface of the ironing roller" is meant "covering any point of the ironing surface of the ironing roller" or "covering the entire ironing surface of the ironing roller, for example, as a fine mesh such that the moisture content throughout the ironing material may influence the electrical resistance between the meter". This resistance controls via the meter 5 the speed of rotation of the ironing roller 1, so that, with increasing moisture 30, the speed of rotation of the ironing roller is reduced. The clothes to be ironed thus remain in the ironing area for an extended period of time so that an optimal ironing result is obtained. For partially dry or completely dry laundry, higher rolling speed is achieved.

I fig. 1 er vist en udførelsesform for opfindelsen, hvor varmevangen 30 som den ene af de to elektroder er elektrisk forbundet med måleren 5. Målerens anden elektrode er anbragt 5 direkte på strygevalsen 1 og direkte under strygeklædet 12.In FIG. 1, an embodiment of the invention is shown in which the heat sink 30 as one of the two electrodes is electrically connected to the meter 5. The other electrode of the meter is placed 5 directly on the ironing roller 1 and directly under the ironing cloth 12.

I den i fig. 1 viste udførelsesform er elektroden udformet som et klæde 13, der er dannet af et elektrisk ledende tekstil eller en folie, der er forsynet med et elektrisk ledende lag.In the embodiment shown in FIG. 1, the electrode is formed as a cloth 13 formed of an electrically conductive textile or foil provided with an electrically conductive layer.

10 Dette klæde 13 omslutter fuldstændig strygevalsen 1, så det i samvirkning med den i givet fald som elektrode udformede varmevange 30 på strygerullen giver en fuldstændig måling af fugtigheden med det til følge, at strygningen forbedres . Den elektriske forbindelse fra den som klæde 13 15 udformede elektrode til måleren 5 består af en forbindelsesleder 14, der er ført til en slæbering 15, hvilken slæbering er anbragt elektrisk isoleret fra strygevalsen l's bærende aksel 2 og aftastes af en slæberingskontakt 16, der er forbundet med måleren 5.This cloth 13 completely encloses the ironing roll 1 so that, in conjunction with the electrode formed as an electrode 30, on the ironing roll, it provides a complete measurement of the moisture, which results in the ironing being improved. The electrical connection from the electrode formed as cloth 13 15 to the meter 5 consists of a connecting conductor 14 which is guided to a grinding ring 15, which grinding ring is electrically insulated from the bearing shaft 2 of the ironing roller 1 and sensed by a grinding contact 16 which is connected. with the meter 5.

20 Den klædeformede elektrode 13 er elektrisk isoleret fra den elastiske bevikling 11. Mellem den klædeformede elektrode 13 og den ligeledes som elektrode udformede varmevange 30 er anbragt et strygeklæde 12, der forhindrer direkte elektrisk kontakt mellem elektroderne, således at der også er 25 et grænselag, hvis der intet strygemateriale er mellem strygevalsen og varmevangen.The cloth-shaped electrode 13 is electrically insulated from the elastic winding 11. Between the cloth-shaped electrode 13 and the heat sink 30 also formed as an electrode, an ironing cloth 12 prevents direct electrical contact between the electrodes, so that there is also a boundary layer. if there is no ironing material between the ironing roller and the heat sink.

I fig. 2 er vist en udførelsesform, hvor varmevangen 30 ligeledes er udformet som den ene af de to elektroder, der står i forbindelse med måleren 5, medens den anden elek-30 trode er anbragt på strygevalsen, således at elektroden udgøres af flere strimmelformede bånd 17, som er fastgjort under strygeklædet 12 på strygevalsen 1. Ved den viste udførelsesform forløber båndene 17 aksialt med hensyn til 141341 5 strygevalsen 1, og hvert bånd 17 er via en forbindelse$le- ϊ der 14 forbundet med slæberingen 15, der som vist i fi^. 1 aftastes af en slæberingskontakt 16 og er forbundet med måleren 5. Båndene 17 kan i givet fald også være ringfonfrede 5 og være anbragt i passende indbyrdes afstand fordelt over strygevalsen l's periferi.In FIG. 2, an embodiment is shown in which the heat sink 30 is also formed as one of the two electrodes communicating with the meter 5, while the other electrode is arranged on the ironing roller, so that the electrode is constituted by several strip-shaped strips 17, which is fixed under the ironing cloth 12 on the ironing roller 1. In the illustrated embodiment, the strips 17 extend axially with respect to the ironing roll 1, and each strip 17 is connected via a connection $ guide 14 to the towing ring 15 which, as shown in FIG. ^. 1 is sensed by a towing contact 16 and connected to the meter 5. The straps 17 may also be ring-lined 5 and, where appropriate, spaced apart at the periphery of the ironing roller 1.

Udover den i fig. 2 viste udførelsesform er det naturligvis også muligt ud fra materialebesparelseshensyn at erstatte båndene 17, der har en vis bredde, med enkeltledere, der 10 enten kan være anbragt fordelt aksialt ellerradialt med hensyn til strygevalsen. Under alle omstændigheder er det imidlertid nødvendigt med et forholdsvis stort antal ledere t for at sikre en tilstrækkelig registrering af strygematerialets fugtighed.In addition to the one shown in FIG. 2, of course, it is also possible, from the point of view of material saving, to replace the strips 17, which have a certain width, with single conductors 10 which can either be disposed axially or radially with respect to the ironing roller. In any case, however, a relatively large number of conductors t is required to ensure adequate recording of the moisture content of the ironing material.

15 Ligeledes er det muligt at påvikle en elektrode, i form af en trådleder, efter en skruelinie på strygevalsen 1 under strygeklædet 12.It is also possible to wind an electrode, in the form of a wire conductor, following a helical line on the ironing roller 1 under the ironing cloth 12.

I fig. 3 er der vist en foretrukken udformning af opfindelsen, hvor den elastiske bevikling 11 består af et elek-20 trisk ledende materiale. Den elastiske bevikling 11's overflade kan derved udgøre den ene elektrode, uden at ekstra konstruktionselementer af den grund er nødvendige. Som materiale til den elastiske bevikling kan man f.eks. anvende ståluld, eller elektrisk ledende plast. Det er 25 dog også muligt at forsyne en ikke-ledende, elastisk bevikling 11's overflade 11a med en eksempelvis påsprøjtet galvanisering eller et ved en lignende metode påsmurt elektrisk ledende lag, som via tilledningen 14 er forbundet med slæberingen 15.In FIG. 3, there is shown a preferred embodiment of the invention in which the elastic winding 11 consists of an electrically conductive material. The surface of the elastic winding 11 can thereby constitute one electrode, without the need for additional structural elements. As a material for the elastic winding, one can e.g. Use steel wool, or electrically conductive plastic. However, it is also possible to provide the surface 11a of a non-conductive, elastic winding 11 with, for example, sprayed galvanizing or an electrically conductive layer lubricated by a similar method, which is connected to the towing ring 15 via the conduit 14.

30 Udførelsesformen ifølge fig. 4 adskiller sig fra de ovenstående ved,at begge elektroder er anbragt på strygevalsen 1 således, at varmevangen ikke benyttes til måling af fugtighed.30 The embodiment of FIG. 4 differs from the above in that both electrodes are arranged on the ironing roller 1 so that the heat sink is not used for measuring humidity.

Claims
