Opfindelsen angår en tromle til en vaskemaskine af den i krav l's indledning angivne art. Sådanne tromler har i almindelighed en konstruktion som er enkel og relativ billig og let at vedligeholde.The invention relates to a drum for a washing machine of the kind specified in the preamble of claim 1. Such drums generally have a construction which is simple and relatively inexpensive and easy to maintain.

5 Det er formålet med opfindelsen at anvise en tromle- konstruktion, som yderligere kan forenkle maskinens fremstilling og stærkt reducere dens fremstillingspris.It is an object of the invention to provide a drum structure which can further simplify the manufacture of the machine and greatly reduce its manufacturing cost.

Dette formål opnås ved hjælp af de i krav l's kendetegnende del angivne midler til sammenføjning af de to 10 cirkulære sidevægge og den cylinderformede plade til en tromle.This object is achieved by means of the means specified in claim 1 for joining the two circular side walls and the cylindrical plate to a drum.

Krav 2 angiver en foretrukken udførelsesform, hvor de kileformede partier yderligere sikrer en pålidelig forankring af fremspringene i sidestykkerne.Claim 2 indicates a preferred embodiment wherein the wedge-shaped portions further ensure a reliable anchoring of the projections in the side pieces.

15 De i krav 3 angivne foranstaltninger medfører at der på enkel måde kan tilvejebringes en adgangsåbning i tromlen, medens krav 4 angiver en hensigtsmæssig detalje ved drivorganerne til tromlens drift.The measures set out in claim 3 mean that an access opening in the drum can be provided in a simple manner, while claim 4 indicates an appropriate detail of the drum drive means.

Opfindelsen vil nu blive forklaret nærmere under hen-20 visning til et udførelseseksempel og tegningen, på hvilken fig. 1 er et perspektivisk, skematisk billede af en vaskemaskine med en tromle ifølge opfindelsen, fig. 2 viser det udfoldede tromlehus set ovenfra, 23 fig. 3 viser den ene af tromlens sidevægge set fra siden, fig. 4 er et tværsnit i forstørret skala af en sidevægs kantparti, idet dette tværsnit er taget langs linien I-I i fig. 3, og 145124 2 fig. 5 er et perspektivisk billede i forstørret skala af et tværsnit af en sidevægs kantparti på det sted, hvor der findes en åbning til fastgørelseselementerne, idet dette tværsnit er taget langs linien 11 — 11 i fig. 4.The invention will now be explained in more detail with reference to an exemplary embodiment and the drawing, in which fig. 1 is a perspective schematic view of a washing machine with a drum according to the invention; FIG. 2 is a plan view of the unfolded drum housing; FIG. 3 is a side view of one of the side walls of the drum; FIG. 4 is an enlarged cross-sectional view of a side wall edge portion, this cross-section taken along line I-I of FIG. 3, and FIG. 5 is an enlarged scale perspective view of a cross-section of a side wall edge portion at the location of an opening for the fasteners, this cross-section taken along line 11-11 of FIG. 4th

5 Den i fig. 1 viste maskine består af beholderen 1, trom- ken 2 og låget 3. Tromlen 2, som hovedsageligt består af et cylindrisk hus 4 og to cirkulære sidevægge 3, er anbragt drejeligt ved, at sidevæggene hver er forsynet med en centralt placeret tap, som er lejret i et leje, 10 der er anbragt på indersiden af beholderens væg.5 The embodiment of FIG. 1, the machine 1 consists of the container 1, the drum 2 and the lid 3. The drum 2, which consists mainly of a cylindrical housing 4 and two circular side walls 3, is pivotally arranged in that the side walls are each provided with a centrally located pin, which is housed in a bearing 10 disposed on the inside of the container wall.

Tromlen kan drives ved, at dens periferiske yderkant er forsynet med en tandkrans 6. Fortrinsvis udgør denne tandkrans en del af sidevæggen 5; sidevæggen 5 og tand-kransen 6 kan således være lavet af formstof som en en-15 kelt enhed.The drum can be operated by having its peripheral outer edge provided with a dental crown 6. Preferably, this dental crown forms part of the side wall 5; The side wall 5 and the tooth rim 6 can thus be made of plastic as a single unit.

Når maskinens låg 3 lukkes, griber et tandhjulsdrev 8 ved den viste udførelsesform ind i tandkransen 6, således at en motor 7,9 i denne position kan drive tromlen.When the lid 3 of the machine is closed, a gear drive 8 in the embodiment shown engages the gear ring 6 so that a motor 7,9 in this position can drive the drum.

Tromlen er let tilgængelig.The drum is easily accessible.

20 Såvel tromlens sidevægge 5 som det perforerede hus 4 er fremstillet af formstof. Samlingen af huset og de to sidevægge udføres som låsekobling, således at der dannes en tromle. Til dette formål er huset 4, der er vist udfoldet i fig. 2 forsynet med et antal parvis an-25 bragte fremspring 11 langs med dets sidekanter 10, som skal fastgøres til sidevæggene 5. Disse noget fjedrende fremspring 11 er indrettet til at glide ind i åbningen 12 (fig. 3) i bunden af en cirkulær rille 13, der har et rektangulært tværsnit. Denne rille 13 er udfor-30 met i den periferiske kant af sidevæggen 5. Kanten 10 på huset 4, som har forstærkningsribber 14, og som er fremstillet i form af et fladt stykke, bringes til at glide ind mod tæt pasning i rillen 13 efter at være ble-Both the drum side walls 5 and the perforated housing 4 are made of plastic. The assembly of the housing and the two side walls is carried out as a locking coupling to form a drum. For this purpose, the housing 4 shown in fig. 2, provided with a plurality of pairs of projections 11 along its lateral edges 10 to be secured to the side walls 5. These somewhat resilient projections 11 are arranged to slide into the opening 12 (Fig. 3) at the bottom of a circular groove. 13 having a rectangular cross section. This groove 13 is formed in the circumferential edge of the sidewall 5. The edge 10 of the housing 4, which has reinforcing ribs 14 and is made in the form of a flat piece, is slid into close fit in the groove 13 after to be-
