Description
Kad stroja za pranje perilaBathtub washing machine
Izum v okviru tekočih življenjskih potrebščin spada na področje obdelave tekstila, namreč pranja oz. natančneje k pralnim strojem, in sicer k podrobnostim pralnih strojev, še zlasti v območju okrova in kadi z bobnom. Tovrstni izumi so po Mednarodni patentni klasifikaciji uvrščeni v razred D 06 F 37/26.The invention in the context of liquid consumer goods belongs to the field of textile processing, namely washing or. more specifically to washing machines, namely to the details of washing machines, especially in the area of the casing and drum tub. According to the International Patent Classification, such inventions are classified in class D 06 F 37/26.
Izum se nanaša na kad stroja za pranje perila, pri katerem je v okrovu vgrajena kad, v njej pa je vstavljen na horizontalni gredi uležajen in motorno gnan boben, omenjeno kad pa se da zapreti z vrati, ki so na voljo v omenjenem okrovu, in jo zatesniti s tesnilno manšeto, ki je vstavljena med odprtino v kadi in vratno odprtino v okrovu.The invention relates to a bathtub of a washing machine, in which a bath is installed in the housing, in which a drum mounted on a horizontal shaft is inserted, and said bath can be closed by a door available in said housing, and seal it with a sealing sleeve inserted between the opening in the tub and the door opening in the housing.
Pri tem je izum osnovati na problemu, kako zasnovati kad s tolikšno inercijsko maso, da bi to zadostovalo za odpravo dodatne uteži, ki je sicer potrebna za izravnavo inercijskih mas med pranjem vsakokrat v bobnu prisotne količine omočenega perila, s čimer bi bilo v kontekstu povečanja ekonomičnosti izdelave možno zmanjšati tako število sestavnih delov kot tudi vložek dela, potrebnega za izdelavo komponent in potem sestavljanja kadi oz. pralnega stroja, obenem pa bi bilo možno z eliminacijo pritrjevanja uteži na kad povečini že vnaprej odpraviti možnost poškodb stičnih mest in nehotenega razstavljanja povezovalnih elementov ter s tem občutno povečati tudi zanesljivost delovanja in podaljšati življenjsko dobo celotnega pranega stroja, razen tega pa naj bi bilo tudi tesnenje med kadjo in okrovom pralnega stroja izvedljivo s pomočjo znanih in preizkušenih manšetnih tesnil, vstavIjivih med cilindrični površini, ki sta med seboj vsaj približno soosni.The invention is based on the problem of how to design a bathtub with such an inertial mass that it would be sufficient to eliminate the additional weight otherwise required to compensate for the inertial masses during washing of the amount of wet laundry present in the drum. cost-effectiveness of production, it is possible to reduce both the number of components and the input of work required for the manufacture of components and then the assembly of the tub or. At the same time, by eliminating the attachment of weights to the tub, it would be possible to eliminate the possibility of damage to the joints and inadvertent disassembly of the connecting elements, thus significantly increasing the reliability of operation and extending the life of the entire washing machine. sealing between the bathtub and the washing machine housing is possible with the aid of known and tested cuff seals, which can be inserted between cylindrical surfaces which are at least approximately coaxial with each other.
Iz stanja tehnike so znane različne izvedbe pralnih strojev s tkzv. frontalnim dostopom, kar pomeni, da je v ogrodju vgrajena kad, v njej pa okoli horizontalne geometrijske osi vrtljiv boben, v katerega se skozi odprtino v steni okrova, ki sejo sicer da zapreti in zatesniti z vrati, vnese za pranje predvideno perilo, nakar se v kad z bobnom in perilom dovede še za pranje potrebno količino vode in pralnih sredstev. Samo pranje se vrši po različnih postopkih in zaporedjih delovnih korakov. Ker pa se med pranjem boben vrti skupaj z znatno količino v njem vstavljenega omočenega perila, se v bobnu in potem tudi kadi pojavljajo neizravnane mase, zaradi katerih potem celoten stroj, ki je običajno zgolj na primernih nogah položen na podlago, izkazuje tendenco tresenja, poskakovanja in neredko tudi premikanja v horizontalni smeri. Neizravnanim masam seje v praksi možno vsaj v pretežni meri izogniti z obtežitvijo kadi, ki predstavlja inercijsko maso, ki se zoperstavlja silam zaradi teže omočenega perila, vrtečega se v bobnu.From the state of the art, various designs of washing machines with so-called frontal access, which means that a bathtub is installed in the frame and a rotating drum rotates around the horizontal geometric axis, into which the laundry intended for washing is introduced through an opening in the wall of the housing, which can otherwise be closed and sealed with a door. bring the required amount of water and detergents to the bath with the drum and laundry. The washing itself is done according to different procedures and sequences of work steps. However, because during washing the drum rotates together with a significant amount of soaked laundry, unbalanced masses appear in the drum and then in the tub, due to which the whole machine, which is usually placed on the ground only on suitable feet, shows a tendency to shake, bounce and often also movements in the horizontal direction. In practice, unbalanced session masses can be avoided, at least to a large extent, by the weight of the tub, which is an inertial mass that resists the forces due to the weight of the soaked laundry rotating in the drum.
V ta namen je na kad bobna pričvrščena utež, kakršna je opisana npr. v SI 20096 A2. Tovrstna utež je zasnovana kot prstan in sestoji iz betona, v katerem je zalita kovinska armatura, tako da iz betona štrlijo pritrdilna ušesa za povezavo uteži s kovinsko kadjo s pomočjo vijakov. Izdelava tovrstne uteži je razmeroma dolgotrajna, saj je potrebno najprej z določeno tehnologijo izdelati kovinsko armaturo, zatem pa to vstaviti v model in jo potem s povsem drugačno tehnologijo zaliti z betonom, čemur sledu še razmeroma dolgotrajno sušenje in šele potem montaža na kad. Zveza med utežjo in kadjo je izpostavljena dinamičnim obremenitvam, ki s časoma lahko privedejo po eni strani do pojava razpok ali lomov, po drugi strani je zlasti armatura izpostavljena tudi koroziji, obstoji pa tudi možnosti popuščanja ali odvijanja povezovalnih elementov.For this purpose, a weight is attached to the drum tub, as described e.g. in SI 20096 A2. This type of weight is designed as a ring and consists of concrete in which metal reinforcement is poured, so that the mounting lugs protrude from the concrete to connect the weights to the metal tub by means of screws. Making this type of weight is relatively time consuming, as it is necessary to first make a metal reinforcement with a certain technology, then insert it into the model and then pour concrete with a completely different technology, followed by relatively long drying and only then mounting on the tub. The connection between the weight and the tub is exposed to dynamic loads, which over time can lead to cracks or fractures, on the other hand, the reinforcement is also exposed to corrosion, and there is also the possibility of loosening or unscrewing the connecting elements.
Izboljšana kombinacija kadi in uteži je opisana tudi v WO 2013/141819 Al, pri tem pa sta izboljšana predvsem vgradnja elementov v utež in kad zaradi zanesljivejše medsebojne povezave, še vedno pa sta za delovanje pralnega stroja potrebna oba omenjena dela.An improved combination of tubs and weights is also described in WO 2013/141819 A1, with the installation of elements in the weight and tub being improved due to a more reliable interconnection, but both of these parts are still required for the operation of the washing machine.
Kot rečeno, je pri tovrstnih pralnih strojih kad pogosto kovinska. V takem primeru je proti koroziji lahko zaščitena bodisi z emajliranjem ali lakiranjem. Zaradi omenjenih dinamičnih obremenitev, izpostavljenosti vodi in detergentom z notranje strani ter vlagi in drugim vplivom z zunanje strani je tako kad načeloma dokaj izpostavljena tudi mehanskim poškodbam in koroziji. Razen tega se med pranjem vsaj med določenimi koraki pranja v boben in kad dovaja vročo vodo, ki pa se zaradi toplotne prevodnosti kovinskega materiala in s tem intenzivnega odvajanja toplote ven iz kadi po nepotrebnem ohlaja in jo je zato potrebno bodisi dogrevati, ali pa je zaradi ohlajanja potem pranje manj učinkovito. Ta fenomen potem vsekakor vpliva tudi na ekonomičnost uporabe pralnega stroja.As said, with this type of washing machine, the tub is often metal. In such a case, it can be protected against corrosion by either enameling or varnishing. Due to the mentioned dynamic loads, exposure to water and detergents from the inside, as well as moisture and other influences from the outside, the bathtub is in principle quite exposed to mechanical damage and corrosion. In addition, hot water is supplied to the drum and the bathtub during washing, at least during certain washing steps. cooling then washing less efficiently. This phenomenon then definitely also affects the economy of using a washing machine.
V izogib omenjenim pomanjkljivostim je v EP 0 601 347 predlagana kad pralnega stroja, ki je izvedena iz plastike. S tem se izognejo problemom s korozijo in toplotno prevodnostjo kadi, vendar pa je plastična kad bistveno lažja od npr. kovinske kadi, zato je za izravnavo sil zaradi vrtenja izsredno nameščenega omočenega perila v bobnu potreben še toliko težji sklop uteži, ki so nameščene na obodu kadi. Kot je možno razbrati iz skic v omenjenem dokumentu, so uteži nameščene v utorih med rebri na površini kadi. To pomeni, da je vzporedno z izdelavo same kadi s pomočjo tehnologije za predelavo plastičnih mas potrebno izdelati tudi npr. betonske uteži in zatem slednje vstaviti na predvidena mesta na površini plastične kadi in potem jih tam fiksirati. To slednje je v kontekstu kasnejših dinamičnih obremenitev med pranjem vsekakor problematično. Lahka in tenkostenska plastika mora namreč med uporabo stroja neprestano prenašati sunke na togo in težko betonsko gmoto, kar pomeni, da so v območju tenkostenskih prehodov med rebro na površini kadi vseskozi pojavljajo občutne koncentracije mehanskih obremenitev, kar pri polimernem termoplastičnem materialu običajno sčasoma privede bodisi do lezenja materialov in razrahljanja povezav, kar pa obremenitve kvečjemu še poveča, ali pa tudi do mehanskih porušitev in razpok. Razen tega je izdelava plastične kadi v primerjavi z ostalimi možnostmi nedvomno znatno dražja.In order to avoid the mentioned shortcomings, a plastic-made bathtub of the washing machine is proposed in EP 0 601 347. This avoids problems with corrosion and thermal conductivity of the tub, but a plastic tub is significantly lighter than e.g. metal tubs, so an even heavier set of weights placed on the perimeter of the tub is required to compensate for the forces due to the rotation of the exceptionally placed soaked laundry in the drum. As can be seen from the sketches in the said document, the weights are placed in the grooves between the ribs on the surface of the tub. This means that in parallel with the production of the tub itself, with the help of plastic processing technology, it is also necessary to produce e.g. concrete weights and then insert the latter in the intended places on the surface of the plastic tub and then fix them there. The latter is certainly problematic in the context of subsequent dynamic loads during washing. Light and thin-walled plastic must constantly withstand shocks to rigid and heavy concrete mass during the use of the machine, which means that significant concentrations of mechanical loads constantly appear in the area of thin-walled transitions between the ribs on the surface of the tub, which usually leads to creep of materials and loosening of joints, which increases the load at most, or even to mechanical fractures and cracks. In addition, the manufacture of plastic tubs is undoubtedly significantly more expensive than other options.
Nadalje je v EP 1 905 880 Al opisana kad pralnega stroja, kije izvedena iz betona, s čimer se je možno izogniti potrebi po izdelavi dodatne betonske uteži in vgradnji le-te na kad in poleg tega doseči tudi druge prednosti kot npr. dovolj slabo toplotno prevodnost, enakomernejšo porazdelitev inercijske mase in s tem učinkovitejše balansiranje, razen tega pa tudi znatno pocenitev izdelave zaradi manjšega števila sestavnih delov, manjše porabe časa, potrebnega za izdelavo, in cenenosti betona kot osnovnega materiala v primerjavi s plastiko ali kovino. V omenjeni rešitvi je predvideno, da se kad izvede iz enega kosa, namreč v obliki enostransko zaprte valjaste cevi, ki je na zaprtem koncu opremljena z v njej zalitim okovjem za prejem ležajev in gredi bobna, na zaprtem koncu pa je prirejena za prejem manšete za tesnenje vrzeli med kadjo in okrovom stroja v območju odprtine na okrovu, ki jo je možno zapreti z vrati, ki so s pomočjo šamirjev zavihtljivo pritrjena na okrovu. Tesnenje med kadjo in okrovom, kakor je razloženo v omenjenem dokumentu, namreč pročelne površine odprtega konca cevaste kadi proti glede na vzdolžno os pravokotni ravni površini okoli okrogle luknje v steni okrova bi bilo izvedljivo kvečjemu s pomočjo posebej izdelanih manšet, ki pa se zdijo na področju izdelave pralnih strojev dokaj nenavadne in se postavlja vprašanje, če je tovrstno tesnenje na dolgi rok sploh lahko izvedeno na dovolj zanesljiv način.Furthermore, EP 1 905 880 A1 describes a bathtub of a washing machine made of concrete, which makes it possible to avoid the need to make an additional concrete weight and install it on the bathtub and to achieve other advantages such as e.g. sufficiently poor thermal conductivity, more even distribution of inertial mass and thus more efficient balancing, as well as a significantly lower cost of production due to fewer components, less time required for production and the cost of concrete as a base material compared to plastic or metal. In the mentioned solution, it is envisaged that the tub is made of one piece, namely in the form of a one-sided closed cylindrical tube, which at the closed end is equipped with fittings for receiving bearings and drum shafts, and at the closed end it is adapted to receive a sealing sleeve. gaps between the tub and the machine housing in the area of the opening on the housing, which can be closed by a door which is hingedly attached to the housing by means of hinges. Sealing between the tub and the casing, as explained in the said document, namely the front surface of the open end of the tubular tub against the longitudinal axis perpendicular to the plane around the round hole in the casing wall would be feasible at most by means of specially designed cuffs. the manufacture of washing machines is quite unusual and the question arises as to whether such sealing can be carried out in a sufficiently reliable manner in the long run.
Izum se nanaša na kad stroja za pranje perila, ki je smiselno zasnovana kot enostransko zaprta cilindrična cev, v katero je skupaj s pripadajočo gredjo soosno vstavljiv okoli horizontalne geometrijske osi vrtljiv boben pralnega stroja in ki na svojem zaprtem koncu obsega ustrezno ojačeno ležišče za prehod in uležajenje omenjene gredi bobna, na svojem odprtem koncu pa sklenjeno cilindrično površino za naleganje tesnilne manšete, ki je po drugi strani prirejena za naleganje na sklenjeni tesnilni površini za dostop v notranjost v kadi vrtljivega bobna predvidene in z vrati zapirljive odprtine v okrovu pralnega stroja, pri čemer kad sestoji iz betona, upoštevajoč vsakokrat za vgradnjo bobna v kad potrebne dimenzije pa je debelina sten kadi tako izbrana, da kad že sama po sebi in brez vsakršne dodatne uteži predstavlja zadostno inercijsko maso za nemoteno delovanje pralnega stroja, in pri čemer je kad na svoji zunanji površini opremljena s primernimi pritrdilnimi ležišči za vgradnjo kadi v okrov pralnega stroja in je pri tem opremljena tudi z vsaj eno odprtino za dovajanje in/ali odvajanje vode in/ali pralnih sredstev v notranjost omenjene kadi oz. ven iz nje.The invention relates to a bathtub of a washing machine, which is meaningfully designed as a one-sided closed cylindrical tube into which a rotating drum of a washing machine is coaxially inserted about a horizontal geometric axis and which at its closed end comprises a suitably reinforced bed for passage and bearing said shaft of the drum, and at its open end a closed cylindrical surface for fitting the sealing sleeve, which on the other hand is adapted to fit on the closed sealing surface for access to the inside of the rotating drum tub provided and door-closing openings in the washing machine housing, at whereby the tub consists of concrete, taking into account the dimensions required for the installation of the drum in the tub, the thickness of the walls of the tub is chosen so that the tub itself and without any additional weight represents sufficient inertial mass for smooth operation of the washing machine. its outer surface equipped with suitable mounting beds for the installation of bathtubs in the housing of the washing machine and is also equipped with at least one opening for the supply and / or discharge of water and / or detergents into the interior of said bath or. out of it.
Kad po izumu sestoji iz enostransko zaprtega cevastega prvega dela in k slednjemu priključenega prstanastega drugega dela, pri čemer omenjen prvi del sestoji iz betona in na omenjenem zaprtem koncu obsega omenjeno ležišče za prejem in uležajenje gredi bobna, na svojem preostalem koncu pa je opremljen s po celotnem obodu potekajočo prirobnico iz termoplastičnega materiala, ki je po celotnem obodu vgrajena v omenjenem betonu in po celotnem obsegu obsega iz betonskega materiala navzven štrleč in neprekinjen zunanji rob, medtem ko prstanasto zasnovan drugi del prav tako sestoji iz betona in na svojem proti prvemu delu obrnjenem koncu obsega po celotnem obodu potekajočo prirobnico iz termoplastičnega materiala, kije po celotnem obodu vgrajena v omenjenem betonu in po celotnem obsegu obsega iz betonskega materiala navzven štrleč in neprekinjen zunanji rob, na primernem odmiku od omenjenega obodnega roba pa je drugi del opremljen s proti njegovemu preostalemu koncu potekajočo cilindrično notranjo naležno površino za prejem omenjene tesnilne manšete, ki je po drugi strani prirejena za naleganje na površini omenjene zapirljive odprtine v okrovu pralnega stroja. Omenjen prvi del in omenjen drugi del sta v območju omenjenih robov omenjenih prirobnic iz termoplastičnega materiala v soosnem položaju med seboj nerazstavljivo in zatesnjeno povezana po svojem celotnem obodu.The tub according to the invention consists of a unilaterally closed tubular first part and an annular second part connected to the latter, said first part consisting of concrete and comprising said bearing at said closed end for receiving and bearing a drum shaft, and at its remaining end is provided with a flange of thermoplastic material extending around the circumference, which is embedded in said concrete along the entire circumference and extends outwards and continuously along the entire circumference of the concrete material, while the ring-shaped second part also consists of concrete and faces towards the first part. at the end it comprises a flange of thermoplastic material extending around the circumference, which is embedded in said concrete along the entire circumference and a protruding and continuous outer edge extending outwards from the concrete material along the entire circumference, the second part being provided with a counter end-running cylindrical int an abutment surface for receiving said sealing sleeve, which on the other hand is adapted to abut on the surface of said sealing opening in the housing of the washing machine. Said first part and said second part are in the area of said edges of said flanges made of thermoplastic material in an adjacent position inseparably and tightly connected to each other along their entire circumference.

Primer izvedbe kadi 100 stroja za pranje perila po Sl. 1 - 4 podobno kot uvodoma obravnavani primeri iz stanja tehnike zadeva kad 100, kije smiselno zasnovana kot enostransko zaprta cilindrična cev, v katero je skupaj s pripadajočo gredjo soosno vstavljiv okoli horizontalne geometrijske osi 105 vrtljiv boben pralnega stroja. Na skici neprikazana gred pralnega stroja je gnana in je v ta namen npr. na svojem izven kadi 100 razporejenem območju opremljena z neprikazano jermenico, ki je preko primernega, prav tako neprikazanega jermena gnana s prav tako neprikazano nadaljnjo jermenico, ki je pritrjena npr. na gredi na skici neprikazanega elektromotorja.An embodiment of the tub 100 of the washing machine according to FIG. 1 - 4, similarly to the examples from the prior art, concerns a tub 100, which is reasonably designed as a one-sided closed cylindrical tube into which a rotating drum of a washing machine is coaxially inserted around the horizontal geometric axis 105 together with the corresponding shaft. The shaft of the washing machine not shown in the sketch is driven and for this purpose e.g. in its area outside the bath 100, equipped with an undisplayed pulley, which is driven via a suitable, also undisplayed belt by an equally undisplayed further pulley, which is attached e.g. on the shaft on the sketch of the electric motor not shown.
Kad 100 na svojem zaprtem koncu 101 (Sl. 1) obsega ustrezno ojačeno ležišče 106 za prehod in uležajenje omenjene gredi bobna, na svojem odprtem nasprotnem koncu 102 pa sklenjeno cilindrično površino 104 za naleganje tesnilne manšete. Omenjena manšeta, ki na skici ni prikazana, je po drugi strani prirejena za naleganje na sklenjeni tesnilni površini za dostop v notranjost v kadi 100 vrtljivega bobna predvidene in z vrati zapirljive odprtine v prav tako neprikazanem okrovu pralnega stroja.The tub 100 at its closed end 101 (Fig. 1) comprises a suitably reinforced bearing 106 for passing and bearing said drum shaft, and at its open opposite end 102 a closed cylindrical surface 104 for fitting the sealing sleeve. Said cuff, which is not shown in the sketch, on the other hand, is adapted to fit on a closed sealing surface for access to the interior in the tub 100 rotating drum provided and door-closing opening in the equally undisclosed housing of the washing machine.
Kad 100 sestoji iz betona, dobljenega z reakcijo in strjevanjem malte, sestoječe iz zmesi cementa, vode in ustreznih aditivov, po izbiri tudi tkzv. mikroarmature, kar potem vsakokrat dobljenemu betonu poleg potrebne statične in dinamične trdnosti zagotavlja tudi ustrezno vodotesnost, termično izolativnost, hitrost strjevanja in druge vsakokrat zahtevane karakteristike. Strokovnjakom bo razumljivo, da je izdelke kot je omenjena kad 100 možno izdelati s poljubno tehniko, kije primerna za izdelavo razmeroma tenkostenskih betonskih izdelkov, vključno s centrifugalnim ulivanjem in zatem strjevanjem betonske mase.The tub 100 consists of concrete obtained by the reaction and hardening of the mortar, consisting of a mixture of cement, water and suitable additives, optionally also the so-called. microreinforcement, which then, in addition to the required static and dynamic strength, also provides the concrete obtained with the appropriate watertightness, thermal insulation, hardening speed and other required characteristics. It will be appreciated by those skilled in the art that products such as the tub 100 can be made by any technique suitable for the manufacture of relatively thin-walled concrete products, including centrifugal casting and subsequent solidification of the concrete mass.
Upoštevajoč vsakokrat za vgradnjo bobna v kad 100 potrebne dimenzije, ki so npr. odvisne od predvidene kapacitete samega stroja za pranje perila, je debelina sten kadi 100 tako izbrana, da kad 100 že sama po sebi in brez vsakršne dodatne uteži predstavlja zadostno inercijsko maso za nemoteno delovanje pralnega stroja. Na ta način pri pralnem stroju z vgrajeno tovrstni kadjo 100 odpade vsakršna potreba po vgradnji dodatnih uteži za kompenzacijo inercijskih mas.Considering each time for the installation of the drum in the tub 100 the necessary dimensions, which are e.g. depending on the intended capacity of the washing machine itself, the wall thickness of the tub 100 is chosen so that the tub 100 by itself and without any additional weights represents a sufficient inertial mass for the smooth operation of the washing machine. In this way, with a washing machine with a built-in bathtub of this type 100, there is no need to install additional weights to compensate for inertial masses.
Kad 100 je na svoji zunanji površini 107 opremljena s primernimi pritrdilnimi ležišči 108 za vgradnjo kadi 100 v okrov pralnega stroja. Razen tega je kad 100 opremljena tudi z vsaj eno odprtino za dovajanje in/ali odvajanje vode in/ali pralnih sredstev v notranjost omenjene kadi 100 oz. ven iz nje.The tub 100 is provided on its outer surface 107 with suitable mounting bearings 108 for installing the tub 100 in the housing of the washing machine. In addition, the tub 100 is also equipped with at least one opening for supplying and / or draining water and / or detergents into the interior of said tub 100 or. out of it.
Za kad 100 po izumu je značilno, da je izvedena iz prvega enostransko zaprtega cevastega dela 1 in k slednjemu priključenega prstanastega drugega dela 2. Omenjen prvi del 1 sestoji iz betona in na omenjenem zaprtem koncu 101 obsega omenjeno ležišče 106 za prejem in uležajenje gredi bobna, na svojem preostalem koncu 102 pa je opremljen s po celotnem obodu potekajočo prirobnico 12 iz termoplastičnega materiala, kije po celotnem obodu vgrajena v omenjenem betonu in po celotnem obsegu obsega iz betonskega materiala navzven štrleč neprekinjen zunanji rob 120. Omenjen prstanasto zasnovan drugi del 2 prav tako sestoji iz betona in na svojem proti prvemu delu 1 obrnjenem koncu 21 obsega po celotnem obodu potekajočo prirobnico 22 iz termoplastičnega materiala, ki je po celotnem obodu vgrajena v omenjenem betonu in po celotnem obsegu obsega iz betonskega materiala navzven štrleč neprekinjen zunanji rob 220. Razen tega je drugi del 2 na primernem odmiku od obodnega roba 220 opremljen s proti njegovemu preostalemu koncu 23 potekajočo cilindrično notranjo naležno površino 104 za prejem omenjene tesnilne manšete, ki je po drugi strani prirejena za naleganje na površini omenjene zapirljive odprtine v okrovu pralnega stroja.The tub 100 according to the invention is characterized in that it is made of a first unilaterally closed tubular part 1 and an annular second part 2 connected to the latter. Said first part 1 consists of concrete and at said closed end 101 comprises said bearing 106 for receiving and bearing a drum shaft , at its remaining end 102 it is provided with a thermoplastic flange 12 extending around the entire circumference, which is embedded in said concrete around the entire circumference and a continuous outer edge 120 protruding outwards from the concrete material along the entire circumference. it thus consists of a concrete and at its end facing the first part 1 comprises a flange 22 made of thermoplastic material extending around the entire circumference, which is embedded in said concrete around the entire circumference and a continuous outer edge protruding outwards from the concrete material over the entire circumference. of which the second part 2 is provided at a suitable distance from the circumferential edge 220 a cylindrical inner bearing surface 104 extending to this remaining end 23 for receiving said sealing sleeve, which on the other hand is adapted to rest on the surface of said closing opening in the housing of the washing machine.
