Description
15 20 30 35 468 274 2 1 bakre ände, som inte visas i figuren, är på sedvanligt sätt försett med en anslutning för en slang som i sin tur är ansluten till en med en kran försedd vattenledning. Duschhandtagets 1 främre ände är försedd med en stril 2. The rear end, which is not shown in the figure, is in the usual way provided with a connection for a hose which in turn is connected to a water pipe provided with a tap. The front end of the shower handle 1 is provided with a sprinkler 2.
Duschhandtaget 1 är försett med en kanal 3 genom vilken vat- ten är avsett att strömma i pilens A riktning. Kanalen 3 har lämpligen cirkulärt tvärsnitt och har en förträngning 4 vid sin vänstra ände innan den övergår i ett i huvudsak konformat rum 5.The shower handle 1 is provided with a channel 3 through which the water is intended to flow in the direction of the arrow A. The channel 3 suitably has a circular cross-section and has a constriction 4 at its left end before it merges into a substantially cone-shaped space 5.
Ett cirkulärt hål 6 är upptaget i handtagets 1 sidovägg.A circular hole 6 is received in the side wall of the handle 1.
En ejektorventil 7 med till största delen cirkulärt tvär- snitt är inbyggd eller alternativt löstagbart införd i kanalen 3 och förhindras att vrida sig i denna beroende på att förträng- ningen 4 och ventilens 7 med denna samverkande, främre ände inte är cirkulärt utformade. Ventilens 7 bakre ände är försedd med en ringformig fjädrande fläns 8 som tätande anligger mot kanalens 3 sidoväggar. Ventilen 7 kan förses med medel för att fasthålla den axiellt i kanalen 3 men detta är vanligtvis inte nödvändigt eftersom det mot flänsen 8 verkande vattentrycket trycker ven- tilen mot förträngningen 4.An ejector valve 7 with a largely circular cross-section is built-in or alternatively removably inserted into the channel 3 and is prevented from rotating therein due to the constriction 4 and the valve 7 with this cooperating front end not being circularly designed. The rear end of the valve 7 is provided with an annular resilient flange 8 which abuts against the side walls of the channel 3. The valve 7 can be provided with means for holding it axially in the channel 3, but this is usually not necessary since the water pressure acting against the flange 8 presses the valve against the constriction 4.
Ejektorventilen 7, som saknar rörliga delar, är försedd med en axiell kanal bestående av koaxiella delkanaler 9a och 9b, som båda har mindre tvärsnitt än kanalens 3 tvärsnitt och därför begränsar det genom ventilen passerande vattenflödet. Kanalen 9b avgränsas av ett i den lämpligen av plast tillverkade ventilen 7 fastsatt metallrör, vars vänstra ände utskjuter i den med större tvärsnitt försedda delkanalen 9a.The ejector valve 7, which has no moving parts, is provided with an axial channel consisting of coaxial sub-channels 9a and 9b, both of which have smaller cross-sections than the cross-section of the channel 3 and therefore limit the water flow passing through the valve. The channel 9b is delimited by a metal tube fixed in the suitably made valve made of plastic, the left end of which projects into the sub-channel 9a provided with a larger cross-section.
I området där kanalen 9b övergår i kanalen 9a är en radiell luftkanal 10 upptagen i ventilens 7 sidovägg. Kanalens 10 cent- rumakels förlängning är belägen i samma plan som eller ett kort stycke från rörets 9b vänstra ände. Kanalens 10 inlopp är place- rat på stort avstånd från hålet 6 i handtagets 1 sidovägg, lämp- ligen diametralt motsatt detta, vilket visas på figuren. Kana- lens 10 inlopp står i förbindelse med det mellan ventilen 7 och kanalens 3 sidovägg bildade, ringformade utrymmet 11 som är luftfyllt och som sträcker sig mellan förträngningen 4 och flän- sen 8.In the area where the duct 9b merges into the duct 9a, a radial air duct 10 is accommodated in the side wall of the valve 7. The extension of the channel's of center of the channel 10 is located in the same plane as or a short distance from the left end of the tube 9b. The inlet of the channel 10 is located at a large distance from the hole 6 in the side wall of the handle 1, suitably diametrically opposite this, as shown in the figure. The inlet of the duct 10 communicates with the annular space 11 formed between the valve 7 and the side wall of the duct 3, which is air-filled and which extends between the constriction 4 and the flange 8.
Anordningens enligt uppfinningen funktion kommer nu att be- skrivas i korthet. Ö.\ 10 15 20 30 35 468 274 Den genom kanalen 9b i pilens A riktning inmatade vat- tenströmmen blandas med den genom kanalen 10 genom ejektor- verkan insugna luftströmmen i omradet omedelbart efter rörets 9b vänstra ände. Vatten-luftströmmen passerar genom kanalen 9 och vidare ut i utrymmet 5 varefter den pressas ut genom strilen. Genom lämplig dimensionering av ventilen 7 och handtaget 1 uppnàs en önskad luftinblandning av 20-30% i vattnet. Detta ger i huvudsak samma duscheffekt som med endast vatten och mjukare strålar men ger 20-30% minskad vattenförbrukning. Genom att dessutom kanalen 9b har betydligt mindre tvärsnitt än kanalen 3 àstadkommes en ytterligare vat- tenbesparing, och totalt kan mer än 50% och ända upp till ca 70% av vattenförbrukningen sparas i förhållande till kon- ventionella duschhandtag med i huvudsak bibehållen dusch- effekt.The function of the device according to the invention will now be described in brief. The water flow fed through the channel 9b in the direction of the arrow A is mixed with the air flow sucked in through the channel 10 by the ejector action immediately after the left end of the pipe 9b. The water-air flow passes through the channel 9 and further out into the space 5 after which it is forced out through the nozzle. By suitable dimensioning of the valve 7 and the handle 1, a desired air mixture of 20-30% in the water is achieved. This gives essentially the same shower effect as with only water and softer jets, but gives 20-30% reduced water consumption. In addition, because the channel 9b has a significantly smaller cross-section than the channel 3, an additional water saving is achieved, and in total more than 50% and up to about 70% of the water consumption can be saved in relation to conventional shower handles with mainly maintained shower power. .
Vid luftens insugning genom kanalen 10 insugs luft i utrymmet ll genom hålet 6. Den genom hàlet 6 insugna luften mäste passera runt ventilen 7 innan den insugs i kanalen 10, vilket förhindrar eller avsevärt minskar det oljud som skulle uppstå om hàlet 6 och kanalens 10 inlopp vore belägna nära varandra.When the air is sucked in through the channel 10, air is sucked into the space 11 through the hole 6. The air sucked through the hole 6 must pass around the valve 7 before it is sucked into the channel 10, which prevents or significantly reduces the noise that would occur if the hole 6 and the channel 10 inlet would be located close to each other.
Om en lägre luftinblandning önskas än den som anord- ningen enligt uppfinningen är konstruerad för, såsom vid sköljning av har, täcks hàlet 6 av ett finger pà den hand som haller duschhandtaget 11. Om hálet 6 täcks helt sker ingen luftinblandning alls, och luftinblandningen kan regleras melina 0 och 20-30% genom att delvis täcka hàlet. ventilen 7 är, som framgår av figuren, placerad sä nära strilen 2 som möjligt. Anledningen härtill är dels att ven- tilens 7 ejektorverkan blir bättre eftersom blandningspunkten mellan vatten och luft är belägen nära utloppet för vatten- luftblandningen och dels att man vid avstängning av vatten- flödet tiil duschhandtaget 1 fàr en liten vattenmängd i detta nedströms om ventilen, vilket minskar risken för vattenspill. även om endast en utföringsform av anordningen enligt den föreliggande uppfinningen beskrivits ovan och visats pá ritningen torde förstàs att uppfinningen inte är begränsad till denna utföringsform utan endast begränsas av det i patent- kraven angivna.If a lower air mixture is desired than that for which the device according to the invention is designed, as when rinsing hair, the hole 6 is covered by a finger on the hand holding the shower handle 11. If the hole 6 is completely covered, no air mixing takes place at all, and the air mixing can melina 0 and 20-30% are regulated by partially covering the hole. the valve 7 is, as shown in the figure, placed as close to the sprinkler 2 as possible. The reason for this is partly that the ejector effect of the valve 7 is better because the mixing point between water and air is located near the outlet of the water-air mixture and partly that when the water flow to the shower handle 1 is turned off, a small amount of water is obtained downstream of the valve. reduces the risk of water spillage. although only one embodiment of the device according to the present invention has been described above and shown in the drawing, it should be understood that the invention is not limited to this embodiment but is limited only by what is stated in the claims.
