Description

Vynález sa týká víroprúdovej práčky s odstředivkou, pozostávajůcej z vonkájšiého plášťa, v ktorom je umiestnená zvislá pracia nádoba a v nej zvislý perforovaný bubon, spojený v strednej časti jeho dna s jeho hnacím briadelom.The invention relates to a centrifugal washing machine with a centrifuge consisting of an outer jacket, in which a vertical washing vessel and a vertically perforated drum connected to it, in the middle part of its bottom, are connected to its driving ram.

Pádla súčasného stavu techniky bývá perforovaný bubon, ktorý má plniť tak funkciu pracieho bubna ako aj odstředivky, uložený Obvykle súosovo s pranou nádobou, ktorá je válcovitého tvaru. Okrem toho, perforovaný bubon nebývá zvonku opatřený nijakými obvodovými lamelami, či lopatkami, alebo podobnými prostriedkami, ktoré by z vonkajšej strany perforovaného bubna sposobovali vírenie vody. U niektorých konšťruíkcií bývá perforovaný bubon výsuvný poizdlž jeho zvislej osi smerom hoře. Takéto konštrukcie sú relativné zložité a nedosahuje sa u nich dokonalý práci účinok.The paddles of the prior art tend to be a perforated drum, which is intended to fulfill both the function of a scrubbing drum and a centrifuge, usually arranged coaxially with the scoured vessel, which is cylindrical in shape. In addition, the perforated drum is not provided externally with any circumferential slats or blades or the like that would cause water to swirl from the outside of the perforated drum. In some konštruíkcii the perforated drum is extensible along its vertical axis upwards. Such constructions are relatively complex and do not achieve perfect work effect.

Uvedené nevýhody odstraňuje víroprúdová pračka s odstředivkou podlá vynálezu, ktorého podstata spočívá v tom, že perforovaný bubon je zo svojej vonkajšej strany opatřený obvodovými vírnikovými lamelami a hnací briadel' perforovaného bubna, uložený exentricky v dne pracej nádoby, je svojím dolným koncom přesunutý cez nosný mostík, ktorý je svojími patkami, proetredníctvom středných pružných tlmiacich telie230262 tThe above-mentioned disadvantages are eliminated by the centrifugal washing machine with a centrifuge according to the invention, which consists in that the perforated drum is provided with peripheral vane lamellas on its outside and the drive bar of the perforated drum placed eccentrically in the bottom of the washing vessel is moved over its support , which is its feet, through medium elastic damping bodies230262 t

sok opretý o konzoly, ktorých pátky sú spojené so spodným rámom vonkájšiého plášťa, a v oblasti horného okraja pracej nádoby sú medzi ňou a vonkajším plášťom uspoří adané horné pružné tlmlace teliéska.The support is supported on the brackets, the fridges of which are connected to the lower frame of the outer casing, and the upper elastic damping of the body is arranged between the outer casing and the outer casing.

Výhodou práčky podlá vynálezu je, žé v dósledku excentrického uloženia perforovaného hubna, ktorý má funkciu vírqprúdtívého pracieho bubna i odstředivky, ako aj účinkom Obvodových vírnikových lamiel, sa zvýši prací účinok a zároveň sa zníži miera opotrebovania bielizne pri praní. Zníženie opotrebovania sa dosahuje zmiernením tlaku bielizne na vnútornú stranu ohvodovej steny perforovaného bubna v dósledku prúdenia pracieho roztoku smerom dovnútra. Ďalšou výhodou práčky podlá vynálezu je jej účinné odpruženie pri relativné malej technickej náročnosti. Okrem toho je výhodné, keď perforovaný bubon je v mieste spoja s jeho hnacím hriadelom opatrený z jeho vnútornej strany pevným centrálnym vírnikom. Tým sa podstatné zjednodušší spoj perforovaného bubna s hnacím hriadelom bez ujmy na pracej účinnosti. Tiež je výhodné, keď na nosný mostík je zdola upevněný pohon a zhora prostredníctvom ložiskového telesa aj pracia nádoba. Tým :sa vytvoří konstrukčně jednodu230262 $An advantage of the washing machine according to the invention is that due to the eccentric placement of the perforated sponge, which has the function of a swirling drum and a centrifuge as well as the effect of the peripheral vortex lamellae, the washing effect is increased while reducing the wear rate of laundry. A reduction in wear is achieved by relieving the linen pressure on the inner side of the perforated drum wall as a result of the washing solution flowing inwards. A further advantage of the washing machine according to the invention is its effective cushioning at a relatively low technical level. In addition, it is advantageous if the perforated drum is provided with a fixed central gyroplane on its inner side at the point of connection with its drive shaft. This substantially simplifies the connection of the perforated drum to the drive shaft without compromising washing efficiency. It is also advantageous for the drive bridge to be mounted on the support bridge and the washing vessel from above by means of the bearing housing. The: sa team will create a simple230262 $ design

The legs 17 of the two brackets 15, 16 are welded to the lower frame 18 of the outer casing 1. Four lower resilient damping bodies 19 are screwed to the lower frame 18 at the corner parts of the top view of the washing machine. Below the upper edge 20 of the washing container 2, there are three upper, resilient, disposed planes between it and the outer casing 1.

Claims

SUBJECT

1. Whirlpool: washing machine with. a centrifuge consisting of an outer sheath in which the " vertical " wash container is positioned and vertical therein. a perforated drum connected in the central part of its bottom to its drive shaft, characterized in that the perforated drum (3). is provided on its outside with circumferential vane lamellae (7) ... and the drive shaft (5) of the perforated drum (3), which is eccentrically mounted in the bottom (9) of the washing vessel (2), ), which is by its feet (12), supported by means of intermediate elastic damping bodies (13) on brackets (15, 16), whose feet (17) are connected by damping bodies 21. In the middle part of the bottom 4 of the perforated drum 3 is inside 3, a central gyroplane 22 threaded and fixed to the upper end of the drive shaft 5 by means of a thread. In this way, a perforated drum 3 is firmly clamped between the center gyroplane 22 and a mat of suitable plastic. The drive 24 is part of a constructional node based on a support bolt 10 on which the washing vessel 2 is mounted from above via the bearing body 25 and the drive 24 from below.

The washing machine according to the invention operates in such a way that, when the perforated drum 3 is rotated, during the washing and rinsing cycle, the washing solution and / or the washing solution are removed. through the openings 6, the sailing water enters through the openings 6 from places with a smaller distance between the inner wall of the washing vessel 2 and the outer wall of the perforated drum 3, into the inner parts of the perforated drum 3 and on the opposite side again outwards. The water thus oscillates through the openings 6 in and out, one oscillation corresponding to one revolution of the perforated drum 3. The central vortex 22 helps to rotate the water or the washing solution in the perforated drum 3. The mechanical vibrations of the washing vessel 2 are damped by the upper resilient dampers. The entire weight of the scrubber together with the load is then transferred via the brackets 15, 16 to the lower resilient dampers 19. These also include residual vibration of the washing machine.

vynalezu. ....

with a lower frame (18) of the outer casing (1), and in the region of the upper edge (20) of the washing container (2J), upper elastic damping bodies (21) are arranged between it and the outer casing.

2. The washing machine according to claim 1, characterized in that the perforated drum (3) is in place with its drive shaft (5) provided on its inside with a central vortex (22).

Washing machine according to claim 1, characterized in that a drive (24) is mounted on the support bridge (10) from below and a washing container (2) is washed from above by means of the bearing body (25).
