Opfindelsen angår en blandingshane som nærmere angivet i krav 1*8 indledning.The invention relates to a mixing tap as further specified in claim 1 * 8, preamble.

Det vides, at brugeren kan manøvrere regulatorhuset på blandingshanen til hel eller delvis lukning af tilførselsledningerne for koldt og varmt vand til opnåelse af en blanding med den ønskede temperatur.It is known that the user can maneuver the regulator housing on the mixing tap to completely or partially close the cold and hot water supply lines to obtain a mixture with the desired temperature.

Hvis det varme vand er på 40°C, medfører det ingen risiko for brugeren, men det samme gælder ikke ved 80°C.If the hot water is at 40 ° C, this does not pose any risk to the user, but the same does not apply at 80 ° C.

Brugen af blandingshanex kan altså være farlig, hvis de er forbundet med en tilledning af 80°C varmt vand.Thus, the use of mixing hanks can be dangerous if they are connected to a supply of 80 ° C hot water.

På kendte haner som f.eks. ifølge fransk patentansøgning nr, 77 35 147 af 23 HOV 1977 er rotationen af regulatorhuset begrænset til 180° ved tilstedeværelsen af hane-huset af to diametralt modsatte anslag, mod hvert af hvilke kan komme til anlæg en finger hørende til regulatorhusets medbringerhoved.On known cocks such as According to French Patent Application No. 77 35 147 of 23 HOV 1977, the rotation of the regulator housing is limited to 180 ° by the presence of the cock housing of two diametrically opposed abutments, against each of which a finger belonging to the controller head can be brought into contact.

I det franske patentskrift nr, 2,269.666 beskrives en indretning omfattende to koncentriske ringe med hver sit anslag. De to ringe er anbragt således, at de to anslag ligger på samme omkreds, og hver ring kan fikseres på hanehuset ved hjælp af et fortandingsaggregat.French Patent Specification No. 2,269,666 describes a device comprising two concentric rings, each with its own stop. The two rings are arranged so that the two stops are on the same circumference, and each ring can be fixed to the tap housing by means of a toothed assembly.

Til regulering af stillingen af anslagene er det nødvendigt først at forskyde den ene ring aksialt i forhold til den anden til udløsning af fortandingsindgrebet, hvorefter for-tandingen kan finde et nyt indgreb. Den minimale rotationsvinkel er defineret ved tændernes størrelse.In order to regulate the position of the stops, it is necessary first to move one ring axially to the other to release the tooth engagement, after which the tooth can find a new engagement. The minimum angle of rotation is defined by the size of the teeth.

Formålet med opfindelsen er at anvise en blandingshane, som ikke har den kendte tekniks ovenfor forklarede ulemper, og blandingshanen ifølge opfindelsen er ejendommelig ved det i krav l’s kendetegnende del anførte.The object of the invention is to provide a mixing tap which does not have the disadvantages of the prior art as explained above, and the mixing tap according to the invention is characterized by the characterizing part of claim 1.

Det vil ses, at det ene stop er kontinuerligt regulerbart, så at det er muligt uden demontage ved den rette indstilling at begrænse rotationen af medbringerhovedet - til manøvrering af regulatorhuset - til en vinkel under 180°.It will be seen that one stop is continuously adjustable, so that without disassembly at the correct setting it is possible to limit the rotation of the driver head - for maneuvering the regulator housing - to an angle below 180 °.

Til udførelse af reguleringen behøver man blot at løsne møtrikken på hanehuset og at lade den ydre ring dreje sig kontinuerligt.To carry out the adjustment, you simply need to loosen the nut on the male housing and allow the outer ring to rotate continuously.

Opfindelsen skal forklares nærmere i forbindelse med tegningen, hvor fig. 1 viser et snit i en blandingshane ifølge opfindelsen forsynet med en reguleringsindretning, idet hanen er vist i lukket stilling.The invention will be explained in more detail in connection with the drawing, in which fig. 1 shows a section in a mixing tap according to the invention provided with a control device, the tap being shown in the closed position.

fig 2 et snit efter linien II-II i fig. 1, idet snittet er begrænset til hanehuset, fig. 3 et billede i analogi med fig, 1, hvor hanen er i sin åbne stilling, fig. 4 et snit efter linien iy-IV i fig, 1, og fig. 5 et delbillede, med bestanddelene indbyrdes adskilt, som viser indretningen til begrænsning af regulatorhusets rotation.FIG. 2 is a sectional view taken along line II-II of FIG. 1, the section being limited to the male housing; FIG. Fig. 3 is a view similar to Fig. 1, with the male in its open position; 4 is a sectional view taken along the line iy-IV of FIG. 1; and FIG. 5 is a partial view, with the components spaced apart, showing the device for limiting the rotation of the regulator housing.

Det ses på tegningen, at hanen består af et hanehus 1 med cylinderform, som er let at bearbejde, og som er lukket i den ene ende og åbent i den anden.It will be seen from the drawing that the tap consists of a sleeve housing 1 of cylindrical shape which is easy to machinable and which is closed at one end and open at the other.

Hanehuset 1 har to studse 2 og 3 anbragt diametralt modsat for henholdsvis varmt og koldt vand og en studs 4 for det blandede vands udløb.The faucet housing 1 has two studs 2 and 3 located diametrically opposite for hot and cold water, respectively, and a stud 4 for the outlet of the mixed water.

De to studse 2 og 3 udmunder i hanehuset 1, hvori der drejeligt er anbragt et cylindrisk regulatorhus 5 med en lysning 6, hvis bredde varierer fra den ene ende til den anden. Som vist i fig. 1 og 3 er det muligt ved en drejning på 180° af regulatorhuset 5 at tillukke det ene eller det andet vandtilløb.The two studs 2 and 3 open into the housing housing 1, in which a cylindrical regulator housing 5 is arranged with a groove 6, the width of which varies from one end to the other. As shown in FIG. 1 and 3, it is possible to close one or the other inlet at a 180 ° turn of the regulator housing 5.

Det stillede problem består i ved en passende regulering at reducere rotationsvinklen for regulatorhuset 5 på en sådan måde, at man ikke helt åbner indløbet for det varme vand, men at der i den helt åbne stilling for det varme vand tilledes en vis mængde koldt vand, så at den maksimale temperatur ikke overstiger en i forvejen fastlagt temperatur på f.eks. 40°C.The problem posed is, by appropriate control, reducing the angle of rotation of the regulator housing 5 in such a way that the inlet is not fully opened for the hot water, but that in the fully open position for the hot water a certain amount of cold water is allowed. so that the maximum temperature does not exceed a pre-determined temperature of e.g. 40 ° C.

Ifølge opfindelsen opnås dette resultat, idet man benytter to koncentriske ringe 7 og 8, som hver har et anslag indskudt i banen for en finger 11, som bæres af regulatorhusets 5 medbringerhoved 12. Som vist på tegningen har ringene to anslag, henholdsvis 9a-9b og lOa-lOb, som er fremkommet 147549 3 ved, at man har spaltet enden af hver ring i en plan parallel Tied dens akse og fjernet materialet på den ene side af spaltningsplanen.According to the invention, this result is obtained by using two concentric rings 7 and 8, each having a stop inserted in the path of a finger 11 carried by the carrier head 12 of the regulator housing 5. As shown in the drawing, the rings have two stops, respectively 9a-9b. and 10a-10b, obtained by splitting the end of each ring in a plane parallel to its axis and removing the material on one side of the splitting plane.

På denne måde vil man forstå, at det ved vinkelforskydning af de to ringe 7 og 8 er muligt at begrænse rotati-nen af medbringerhovedet 12 til en værdi under 180°, nemlig den, som adskiller anslagene 9a-10b i fig. 4 og 5.In this way, it will be understood that by angular displacement of the two rings 7 and 8 it is possible to limit the rotation of the carrier head 12 to a value below 180 °, namely that which separates the stops 9a-10b in FIG. 4 and 5.

Ifølge en udførelsesform danner ringen 7 forlængelsen af en told 13 til styring af det rørformede endeparti 14 af regulatorhuset 5, som er rotationsforbundet med medbringerhovedet 12, Til dette formål har yderpartiet af det rørformede endeparti 14 en halvflade 15, som samarbejder med en anden halvfladedel 16 i medbringerhovedet 12.According to one embodiment, the ring 7 forms the extension of a duty 13 for controlling the tubular end portion 14 of the regulator housing 5, which is rotationally connected to the carrier head 12. For this purpose, the outer portion of the tubular end portion 14 has a half surface 15 which cooperates with another half surface 16. in the carrier head 12.

Hingen 7 har en krave 17, og ringen 8 har en krave 18, som navnlig tillader at blokere de to ringe i forhold til hanehuset 1 ved hjælp af en møtrik 19.The ring 7 has a collar 17 and the ring 8 has a collar 18 which in particular allows to block the two rings with respect to the cock housing 1 by means of a nut 19.

Da det er vigtigt, at anslagene 9a-9h er rigtigt anbragt i forhold til vandtilledningerne, har tolden 13 et fremspring 20, som træder ind i en lejring i hanehuset 1.Since it is important that the stops 9a-9h are properly positioned in relation to the water pipes, the customs 13 has a projection 20 which enters a bearing in the male housing 1.

Enden af det rørformede endeparti 14 modsat medbring©1*10-yedet 12 danner hanens sæde 21 og er normalt lukket af en ventilklap 22, som bæres af et stempel 23 i tidsregulerimgsmekanismee. Reguleringsmekanismen udgøres af et hus 24, som dublerer hanehuset 1, hvis ende begrænser indføringen af regulatorhuset 5 i hanehuset.The end of the tubular end portion 14 opposite the carrier 1 * 10 face 12 forms the seat 21 of the male and is normally closed by a valve flap 22 carried by a piston 23 in timing mechanism. The control mechanism is constituted by a housing 24 which doubles the cock housing 1, the end of which restricts the insertion of the regulator housing 5 into the cock housing.

Stemplet 23 er aksialt forbundet med en spindel 25, som går gennem det rørformede endeparti 14 og er i fast for-, bindelse med medbringerhovedet 12. Spindelen 25 bærer en hjælpeklap 26, som gør det muligt at afbryde forbindelsen mellem det reguleringskammer 27, som dannes af huset 24 og stemplet 23, og sædet 21 under indvirkning af en fjeder 28, som er indskudt mellem tolden 13 og medbringerhovedet.The piston 23 is axially connected to a spindle 25 which passes through the tubular end portion 14 and is in fixed communication with the carrier head 12. The spindle 25 carries an auxiliary flap 26 which makes it possible to disconnect the control chamber 27 which is formed of the housing 24 and the plunger 23, and the seat 21 under the action of a spring 28 inserted between the customs 13 and the carrier head.

Idet man påvirker medbringerhovedet 12, bevirker man en løftning af hjælpeklappen 26, hvilket letter indføringen af stemplet, og derefter løftningen af hovedklappen;, det vand, som trænger ind i regulatorhuset 5 gennem dets lysning 6, træder ud derfra gennem åbninger 29 og træder ind i det rør- 4 147349 formede endeparti 14, 0g det træder ud fra dette gennem åbninger 30 for at trænge ind i et blandingskammer 31, som er dannet af den indre væg af hanehuset 1 og en rille i tolden 13. Kammeret 31 står i forbindelse med udløbsstudsen 4 ved hjælp af en kanal 32 (fig. 2).By actuating the carrier head 12, a lifting of the auxiliary flap 26 is effected which facilitates the insertion of the plunger, and then the lifting of the main flap; the water which enters the regulator housing 5 through its illumination 6 exits therefrom through openings 29 and enters in the tubular end portion 14, and exits thereto through apertures 30 to penetrate a mixing chamber 31 formed by the inner wall of the faucet housing 1 and a groove in the customs 13. The chamber 31 communicates with the outlet plug 4 by means of a channel 32 (Fig. 2).

Idet man slipper medbringerhovedet 12, fremkalder man på kendt måde begyndelsen af tidsreguleringen.Release of the carrier head 12 in a known manner induces the beginning of time control.

Medbringerhovedet 12 opfylder således en dobbelt funktion: Eet tillader at regulere temperaturen af blandingen ved sin rotation samt at udløse hanens åbning ved sin aksiale forskydning.The carrier head 12 thus fulfills a dual function: It allows to regulate the temperature of the mixture during its rotation and to trigger the opening of the male by its axial displacement.
