Manøveranordning for strømbryter med et elastisk eftergivende lukket kammer. Maneuvering device for circuit breaker with an elastically compliant closed chamber.
Oppfinnelsen vedrører en manøveranord-ning for strømbryter utformet med et elastisk The invention relates to a maneuvering device for a circuit breaker designed with an elastic
ettergivende lukket kammer, av hvilket en del compliant closed chamber, of which a part
er fast anbragt i en uttagning i en fast vegg, is fixed in a recess in a fixed wall,
grensende mot en lukket beholder, som i det bordering on a closed container, as in it
minste delvis er forsynt med en ettergivende least partially is provided with a compliant
lukket, ytre vegg, anordnet inntrykkbar i det av closed, outer wall, arranged impressionable in that of
beholderen omsluttete rom, og at i kammerveggen i uttagningen i den faste vegg er anordnet the container enclosed space, and that in the chamber wall in the recess in the fixed wall is arranged
en åpning, som er forsynt med en ventil utformet for bare å lede luft fra den lukkete beholder an opening, which is provided with a valve designed to only direct air from the closed container
til det lukkete kammer, samt at videre en annen to the closed chamber, as well as that further another
ventil er anbragt i den lukkete beholders vegg valve is placed in the wall of the closed container
på en sådan måte at luft kan strømme inn i den in such a way that air can flow into it
lukkete beholder gjennom denne andre ventil. closed container through this second valve.
Manøverorgan av dette og lignende slag er Maneuvers of this and similar kinds are
tidligere kjente, slik som pnevmatiske reléer. previously known, such as pneumatic relays.
Disse har imidlertid vært så komplisert oppbyg-get og derved så kostbare i fremstilling at de However, these have been so complicated in structure and thus so expensive to manufacture that they
derfor ikke har kunnet anvendes i standard- therefore could not be used in standard
apparater, som går ut i store serier, som f. eks. husholdningsvaskemaskiner. De har heller ikke ved sin oppbygning egnet seg for anvendelse for slike maskiner, hvor risiko for inntrengende vann har vært stor, f. eks. vaskemaskiner. appliances, which go out in large series, such as e.g. household washing machines. Nor, due to their structure, have they been suitable for use in such machines, where the risk of penetrating water has been great, e.g. washing machines.
Disse og andre ulemper ved manøveranord-ninger av dette slag er ved oppfinnelsen elimi-nert først og fremst ved at kammeret står i forbindelse med atmosfæren gjennom en annen åpning, forsynt med et organ med en bestemt, fortrinnsvis forholdsvis stor strømningsmotstand for luften, og er forsynt med en ettergivende husdel, som ved fylling og tømming av beholderen med luft påvirker strømbryteren til å slutte eller bryte en strømkrets. These and other disadvantages of maneuvering devices of this kind are eliminated by the invention primarily by the chamber being in connection with the atmosphere through another opening, provided with a device with a specific, preferably relatively large flow resistance for the air, and is provided with a compliant housing part, which, when filling and emptying the container with air, affects the circuit breaker to close or break a circuit.
Risiko for ikke ønsket bryting eller sluttirig av en sådan strømkrets ér meget mindre ved anvendelse av manøveranordningen ifølge' oppfinnelsen, arbeidende som ét pnévmatisk- relé, enn ved tidligere vanligvis anvendte elektromag-netiske reléer. The risk of undesired breaking or short-circuiting of such a current circuit is much less when using the maneuvering device according to the invention, working as a pneumatic relay, than with previously commonly used electromagnetic relays.
Manøveranordningen ifølge oppfinnelsen er fordelaktig ved at organet med den bestemte strømningsmotstand for luften består av en hylse innsatt i den andre åpning, i hvilken hylse er anordnet et luftfilter. Derved kan reléets egenskaper lett endres til en for hver anvendelse egnet tidsforsinkelse ved innsetting av forskjellige filterhylser for forskjellige ønskete forsin-kelsestider i reléet manøverarbeide. The maneuvering device according to the invention is advantageous in that the organ with the determined flow resistance for the air consists of a sleeve inserted in the second opening, in which sleeve an air filter is arranged. Thereby, the relay's properties can be easily changed to a time delay suitable for each application by inserting different filter sleeves for different desired delay times in the relay's maneuvering work.
Foråt ikke kravene til filterhylsens utform-ning skal behøve å være for strenge er dertil i den ene ende av organet med den bestemte strømningsmotstand for luften anbragt en endevegg med en forholdsvis liten gjennomstrøm-ningsåpning for luft. In order that the requirements for the design of the filter sleeve do not need to be too strict, an end wall with a relatively small through-flow opening for air is placed at one end of the body with the determined flow resistance for the air.
For manøveranordningens anvendelse, hvor det foreligger risiko for oversprøyting med vann, er dertil fortrinnsvis strømbryteren omsluttet av en nedad åpen skjerm. Ved slike anvendelser har det også vist seg fordelaktig å utforme såvel hele det lukkete kammers hus som hele den lukkete beholders vegg av et elastisk ettergivende materiale, f. eks. gummi. Dette har også sett ut fra prissynspunkt vist seg fordelaktig. For the use of the maneuvering device, where there is a risk of overspray with water, the circuit breaker is preferably enclosed by a downwards open screen. In such applications, it has also proven advantageous to design both the entire housing of the closed chamber and the entire wall of the closed container from an elastically yielding material, e.g. rubber. From a price point of view, this has also proved beneficial.
Oppfinnelsen skal i det etterfølgende beskri-ves i detaljer i forbindelse med anvendelse som et pnévmatisk relé ved slike kombinerte vaskemaskiner og sentrifuger, som omfatter en per-forert trommel for vaskegodset og en beholder som omgir denne og opptar vaskevæsken anordnet innenfor et felles hus. Ved slike maskiner er det kjent å lagre såvel trommel som beholder i et med maskinhusets bunn elastisk forenet stativ likesom å forene beholderens øvre parti ved hjelp av en elastisk hals til maskinhuset. Hen-sikten med disse anordninger er derved mest mulig å forhindre at vibrasjoner som frembrin-ges av trommelen overføres til maskinens hus ved skråbelastning av trommelen. The invention will subsequently be described in detail in connection with use as a pneumatic relay in such combined washing machines and centrifuges, which comprise a perforated drum for the laundry and a container which surrounds this and holds the washing liquid arranged within a common housing. With such machines, it is known to store both the drum and the container in a stand elastically united with the bottom of the machine housing, as well as to unite the upper part of the container by means of an elastic neck to the machine housing. The purpose of these devices is thereby to prevent vibrations produced by the drum from being transferred to the machine's housing when the drum is tilted.
Den etterfølgende detalj beskrivelse av en utførelsesform av oppfinnelsen vedrører en man-øveranordning for ytterligere å eliminere disse vibrasjoner ved at når disse overstiger en viss verdi, reduseres trommelens hastighet momentant slik at vaskegodset automatisk omplaseres til bedre balanse. Utførelsesformen kjenneteg-nes ved et med maskinhuset forenet relé, som omfatter ventilanordninger og to samvirkende belger, utformet som en lukket beholder og et lukket kammer, idet den ene av diss belger, utformet som den lukkete beholder, direkte påvirkes av trykk frembragt f. eks. av en med vaskemaskinens beholder forenet arm e. 1., som via den andre belg, utformet som det lukkete kammer, ved hjelp av en strømbryter omkobler vaskemaskinens motorturtall. The subsequent detailed description of an embodiment of the invention relates to a maneuvering device to further eliminate these vibrations in that when these exceed a certain value, the speed of the drum is momentarily reduced so that the laundry is automatically relocated to a better balance. The embodiment is characterized by a relay united with the machine housing, which comprises valve devices and two cooperating bellows, designed as a closed container and a closed chamber, one of its bellows, designed as the closed container, being directly affected by pressure generated, e.g. . of an arm united with the washing machine's container e. 1., which via the other bellows, designed as the closed chamber, switches the washing machine's engine speed by means of a switch.
Utførelsesformen skal i det etterfølgende be-skrives nærmere under henvisning til tegningen, hvorved ytterligere karakteristiske egenskaper skal bli angitt. In what follows, the embodiment will be described in more detail with reference to the drawing, whereby further characteristic features will be indicated.
På tegningen er fig. 1 et oppriss av en vaske-maskin av tradisjonell type med en manøveran-ordning ifølge oppfinnelsen anbragt i maskinens overdel. Fig. 2 er en detalj ved anordningen sett i snitt. Fig. 3 viser anordningen sett utenifra etter linjen III—III i fig. 2. In the drawing, fig. 1 an elevation of a washing machine of a traditional type with a maneuvering arrangement according to the invention placed in the upper part of the machine. Fig. 2 is a detail of the device seen in average. Fig. 3 shows the device seen from the outside along the line III—III in fig. 2.
På tegningen har tilsvarende deler samme betegnelse. Med 10 er angitt vaskemaskinen som helhet, og 11 er dens drivmotor, som er oppstilt og festet på maskinhusets 12 bunnplate 13 ved hjelp av et fjærende laget stativ 14 og omkring en konsoll 16. Trommelen er omgitt av en beholder 20, som er elastisk forbundet med maskinhusets 12 indre mantelflate 21 ved hjelp av en gummibelg 22. Maskinens lokk er betegnet med 23. Vasketrommelen 18 er på kjent måte forsynt med vulster 24 for vasketøyets omplasering under dets rotasjon resp. oscillasjon. Den anordning som oppfinnelsen ifølge det foranstående vedrører, er et relé for omkobling av motoren med impuls fra vibrasjoner frembragt av maski-nen, dannet ved at trommelen skråbelastes, og er som helhet betegnet med 25. Et impulsorgan som påvirker denne anordning og som kan bestå av en arm, forenet med foran nevnte beholder 20, er betegnet med 26. Reléet består i korthet av en beholder eller belg av gummi e. 1. materiale 27, som er forbundet med kanten av en boks 28 og en til denne forbundet festekappe 29, idet selve kanten av boksen resp. kappen utgjør feste for nevnte beholder 27. I boksen 28 er ennu en belg 31 utformet som et lukket kammer, hvilket er festet i et spor 32 og en flens 33 i boksen 28. I kammerets 31 sentrum resp. i bunnen av boksen er to ventilanordninger 34 og 35 anordnet, idet den sentrale første ventilanordning består av en skive 36 med åpninger 37 og en kjegle 38 av gummi, hvis flens 39 i lukket stilling av ventilen dekker nevnte åpninger 37 og sammen med disse danner en tilbakeslagsventil. In the drawing, corresponding parts have the same designation. 10 denotes the washing machine as a whole, and 11 is its drive motor, which is set up and fixed on the machine housing 12 bottom plate 13 by means of a spring-made stand 14 and around a console 16. The drum is surrounded by a container 20, which is elastically connected with the inner casing surface 21 of the machine housing 12 by means of a rubber bellows 22. The machine's lid is denoted by 23. The washing drum 18 is provided in a known manner with beads 24 for the laundry's relocation during its rotation or oscillation. The device to which the invention relates, according to the above, is a relay for switching the motor with an impulse from vibrations produced by the machine, formed by the drum being loaded obliquely, and is denoted as a whole by 25. An impulse device which affects this device and which can consist of of an arm, united with the above-mentioned container 20, is denoted by 26. The relay briefly consists of a container or bellows of rubber e. 1. material 27, which is connected to the edge of a box 28 and a fastening cover 29 connected to , as the very edge of the box or the cover forms the attachment for said container 27. In the box 28, another bellows 31 is designed as a closed chamber, which is fixed in a groove 32 and a flange 33 in the box 28. In the center of the chamber 31 resp. in the bottom of the box, two valve devices 34 and 35 are arranged, the central first valve device consisting of a disk 36 with openings 37 and a rubber cone 38, whose flange 39 in the closed position of the valve covers said openings 37 and together with these forms a check valve.
I bunnen av boksen ved siden av det foran nevnte kammer 31 er den andre ventil 35 anordnet, hvilken også er utført av gummi og som en tilbakeslagsventil. I kammerets 31 sentrum er anordnet en hylse 41, som inneholder en filt-propp med det formål å regulere strømnings-hastigheten for den luft, som presses ut av kammeret 31, når dette skal trekkes sammen. I hylsens 41 bunn er der åpninger 43, hvis størrelse også bestemmer nevnte strømningshastighet. Bunnen av nevnte hylse 41 ligger an mot en stift 44 i en såkalt mikrobryter 45 for motorens omkobling til passende turtall. In the bottom of the box next to the aforementioned chamber 31, the second valve 35 is arranged, which is also made of rubber and as a non-return valve. A sleeve 41 is arranged in the center of the chamber 31, which contains a felt plug for the purpose of regulating the flow rate of the air that is forced out of the chamber 31 when it is to be pulled together. In the bottom of the sleeve 41 there are openings 43, the size of which also determines said flow rate. The bottom of said sleeve 41 rests against a pin 44 in a so-called microswitch 45 for switching the engine to the appropriate speed.
Om således vaskemaskinens trommel 18 skråbelastes, sammenpresses belgen 27 ved at den påvirkes av armen 26, som er forenet med vaskemaskinens beholder 20. Det trykk som derved dannes forplantes i belgen og gjennom den sentrale første ventil 34 til kammeret 31, idet åpningene 37 frilegges. Luft strømmer derved inn i dette indre kammer 31, som derved utvides. Den ytre andre ventil 35 åpnes derved også, hvorved luft strømmer inn i belgen 27. Samtidig påvirker hylsens 41 bunn mikrobryterens stift 44, slik at vaskemaskinens motor momentant omkobles fra sentrifugeringsturtall til turtall for vasking. Etterat dette er skjedd, går kammeret 31 tilbake til sin opprinnelige form, og sentrlfu-geringsturtallet innkobles igjen av mikrobryte-ren 45. Skulle mangel på balanse i vasketrommelen bibeholdes, omkobles turtallet for motoren igjen til vaske turtall. Dette gjentas til ubalanser i vasketrommelen er forsvunnet ved at vaske-tøyet er blitt omplasert i vasketrommelen under dennes gang ved vasketurtall ved vasketøyets Thus, if the washing machine's drum 18 is loaded obliquely, the bellows 27 is compressed by being affected by the arm 26, which is united with the washing machine's container 20. The pressure that is thereby generated is propagated in the bellows and through the central first valve 34 to the chamber 31, the openings 37 being exposed. Air thereby flows into this inner chamber 31, which thereby expands. The outer second valve 35 is thereby also opened, whereby air flows into the bellows 27. At the same time, the bottom of the sleeve 41 affects the pin 44 of the microswitch, so that the washing machine's motor is instantly switched from centrifugation speed to washing speed. After this has happened, the chamber 31 returns to its original shape, and the centrifugation speed is switched on again by the microswitch 45. Should a lack of balance in the washing drum be maintained, the speed of the motor is switched back to washing speed. This is repeated until imbalances in the washing drum have disappeared due to the laundry being relocated in the washing drum during its cycle at the washing speed at the laundry's
omtumling i vasketrommelen.tumbling in the washing drum.
Med denne utførelsesform av oppfinnelsen With this embodiment of the invention
fåes en j evnere og stillere gang av en sentrifuger-ende trommelvaskemaskin enn hva som vanligvis tidligere har vært tilfellet. a more efficient and quieter operation of a centrifuge-end drum washing machine than has usually been the case in the past.
