Description
Foreliggende oppfinnelse vedrører en trykkføleranord-ning for filtertilstopningsindikatorer for støvsugere med sugestuss som er dreibart anordnet i støvsugerhuset, hvor trykket i sugestussen avføles og overføres til filtertilstopningsindikatoren gjennom en forbindelsesinnretning. The present invention relates to a pressure sensor device for filter clogging indicators for vacuum cleaners with a suction nozzle which is rotatably arranged in the vacuum cleaner housing, where the pressure in the suction nozzle is sensed and transmitted to the filter clogging indicator through a connection device.
Ved slike trykkføleranordninger er det vanlig å sette inn en slange som føres fra stedet for trykkavfølingen til filtertilstopningsindikatoren. Dersom sugestussen, i hvilken trykket blir avfølt, er anordnet dreibar, må With such pressure sensor devices, it is common to insert a hose which is led from the place of pressure sensing to the filter clogging indicator. If the suction nozzle, in which the pressure is sensed, is arranged to be rotatable, must
slangen være lagt i flere slyngninger rundt sugestussen og dessuten oppvise tilstrekkelig fri slangelengde, slik at den ikke ved dreining av sugestussen i vilkårlig retning selv blir forvridd. the hose must be laid in several coils around the suction nozzle and also have sufficient free hose length, so that it does not become distorted itself when the suction nozzle is turned in any direction.
Herved er det en ulempe at slangen stadig blir utsatt for dreie- og knekkpåkjenninger. Dette vil, avhengig av materialet, mer eller mindre raskt ødelegge slangen. Dessuten må det påses at det i rommet hvor slangen er forlagt ikke forekommer skarpe slipekanter eller hjørner, idet også disse med tiden vil ødelegge slangen. This has the disadvantage that the hose is constantly exposed to twisting and buckling stresses. Depending on the material, this will more or less quickly destroy the hose. In addition, it must be ensured that there are no sharp grinding edges or corners in the room where the hose is laid, as these will also destroy the hose over time.
Formålet med oppfinnelsen er således å tilveiebringe en trykkføleranordning hvor forbindelsen mellom trykkav-følingsstedet i den dreibare sugestuss og filtertilstopningsindikatoren fremstilles uten slange. The purpose of the invention is thus to provide a pressure sensor device where the connection between the pressure sensing point in the rotatable suction nozzle and the filter clogging indicator is made without a hose.
Ifølge oppfinnelsen blir denne oppgave løst ved de trekk som er angitt i krav 1. Fordelaktige utførelses-former er angitt i underkravene. According to the invention, this task is solved by the features specified in claim 1. Advantageous embodiments are specified in the subclaims.
Ved oppfinnelsen oppnås det således på fordelaktig måte at det for en filtertilstopningsindikator tilveie-bringes en på avstand beliggende trykkføler uten at det på den dreibare sugestuss er anordnet noen slange. With the invention, it is thus advantageously achieved that a pressure sensor located at a distance is provided for a filter clogging indicator without any hose being arranged on the rotatable suction nozzle.
I det følgende vil et utførelseseksempel på oppfinnelsen bli beskrevet under henvisning til tegningen, In the following, an embodiment of the invention will be described with reference to the drawing,
hvor figuren viser et delsnitt av et støvsugerhus, idet sugestussen og filtertilstopningsindikatoren er vist i snitt. where the figure shows a partial section of a vacuum cleaner housing, with the suction nozzle and the filter clogging indicator shown in section.
Sugestussen 1 er lagret dreibart i støvsugerhuset 2. Mellom sugestussen 1 og støvsugerhuset 2 blir det ved utformningen av sugestussen 1 og støvsugerhuset 2 dannet et omløpende ringkammer 3, som på begge sider 4, 5 avtettes ved hjelp av omløpende ringpakninger 6, 7. Ringpakningene 6, 7 er utformet som såkalte V-pakninger. Inne i ringkammeret 3 er det i sugestussen 1 anordnet en forbindelsesboring 8 som forbinder ringkammeret 3 med det innvendige rom 9 av sugestussen. I rommet 9 er det videre, til beskyt-telse mot inntrengende støv anordnet et filter 12 foran forbindelsesboringen 8. The suction nozzle 1 is stored rotatably in the vacuum cleaner housing 2. Between the suction nozzle 1 and the vacuum cleaner housing 2, the design of the suction nozzle 1 and the vacuum cleaner housing 2 creates a circumferential ring chamber 3, which is sealed on both sides 4, 5 by means of circumferential ring seals 6, 7. The ring seals 6 , 7 are designed as so-called V-seals. Inside the annular chamber 3, a connection bore 8 is arranged in the suction nozzle 1 which connects the annular chamber 3 with the internal space 9 of the suction nozzle. In the space 9, a filter 12 is arranged in front of the connection bore 8 to protect against intruding dust.
Videre er det anordnet en forbindelsesboring 10 i støvsugerhuset, hvilken boring forbinder ringkammeret 3 med en trykkboks 11, således at trykkavfølingen føres fra det indre rom 9 i sugestussen 1 via forbindelsesboringen 8, ringkammeret 3 og forbindelsesboringen 10 til trykkboksen 11. Furthermore, a connection bore 10 is arranged in the vacuum cleaner housing, which bore connects the annular chamber 3 with a pressure box 11, so that the pressure sensing is carried from the inner space 9 in the suction nozzle 1 via the connection bore 8, the annular chamber 3 and the connection bore 10 to the pressure box 11.
Det vil forstås at ved denne anordning vil sugestussen 1 også kunne dreies flere ganger 3 60°, noe som når det er anordnet en slange bare er betinget mulig. It will be understood that with this arrangement the suction nozzle 1 will also be able to be turned several times 3 60°, which is only conditionally possible when a hose is arranged.
