Embodiment Construction

[0031] exist figure 1 shows in a schematic side view a partial area of ​​a washing container 1 of a washing machine and a counterweight 3 fastened to the washing container 1 on the upper side, which balance weight ensures a balanced washing operation. The elongated counterweight 3 extends transversely to the center axis (not shown) of the hollow-cylindrical washing container 1 and rests at its two opposite ends on a hollow-profile support 5 of the washing container 1 . The balancing weights 3 are attached at their longitudinal ends each via a screw connection 7 to an associated hollow-profile support 5 of the washing container 1 .

[0032] The balancing weight 3 is produced in a known manner from a cast material such as cast iron or concrete or another suitable material. The washing container 1 is an injection molded part of synthetic material. The hollow profile support 5 is molded integrally on the washing container 1 in a simple manner in terms of production technology. ...

Abstract

The invention relates to a washing machine comprising an outer tub (1) and a counterweight (3) fastened thereto by means of a screwed connection, said screwed connection having a screw element (9) with two bracing elements (13, 19) at the ends thereof, guided through an opening (17) of the counterweight (3), between which elements the counterweight (3) and a fastening section (29) of the outer tub (1) are braced. According to the invention, at least one of the bracing elements (13, 19) at the ends is configured as a spiked plate (13) having at least one spike-type projection (43) which is forced into the fastening section (29) in the direction of bracing when the counterweight (3) is fastened and non-rotatably secures the spiked plate (13).

Description

technical field [0001] The invention relates to a washing machine according to the preamble of claim 1 . Background technique [0002] In order to support a balanced washing operation of the washing machine, the washing container of the washing machine with the drum rotating inside it is provided with a balance weight. The balance weight can be fixed on the washing container through a threaded connection. [0003] US 2005 / 005650 A1 discloses a threaded connection for fastening a counterweight in a washing container of a washing machine. The threaded connection has a screw which passes through the balancing weight in the assembled position and is screwed into a receiving thread of the washing container. In this case, the screw head is in contact with the stop surface of the counterweight facing away from the washing container. [0004] Another threaded connection for fixing a balancing weight to a washing container is known from DE 42 38 685 A1, wherein in the assembled po...
