Description

FIELD OF THE INVENTION

The present invention relates to a household appliance with a cabinet-shaped body containing several walls, at least one of the walls comprising a structure of extruded elements. In particular, the invention relates to a household appliance for the care of linen, for example, a washing, drying or washing-drying machine.

State of the art

Cabinet-shaped household appliances usually contain at least one drive motor, which during operation, in particular in washing machines, generates vibrations in walls made essentially of sheet metal or plastic. The resulting oscillations cause a number of disadvantages and, in particular, lead to the appearance of unwanted noise. To reduce such disadvantages, in particular, stiffeners are provided on the side walls of the washing machines.

The design patent US D 642 753 S describes a washing machine.

Patent application WO 2010/066653 A1 discloses a household appliance with several walls, at least one of which comprises a structure of extruded elements, wherein the structure of extruded elements contains a first extruded element located in the center of the wall and having a ring shape in plan, a second extruded element located outside the first extruded element and essentially concentrically with it and having a plan in the form of a ring, and at least one third extruded element in the form of a strip located outside the second th extruded element. Although the structure of the first annular extruded element, a concentrically arranged second annular extruded element and the third extruded element in the form of a strip located outside the second extruded element, has improved the vibrational characteristics, the vibrations of the flat surfaces of the walls are still excessive.

Disclosure of the invention

        Thus, the object of the present invention is to overcome the disadvantages inherent in the prior art and to develop a domestic appliance in the form of a cabinet with a housing having improved characteristics.

The problem is solved by an object with the features disclosed in an independent claim. Preferred embodiments of the invention are disclosed in the figures, in the description and in the dependent claims.

According to a first aspect of the invention, the problem is solved by a household appliance with a cabinet-shaped body comprising several walls, the several walls including a front wall, a rear wall, an upper side and a lower side, as well as two side walls, at least one of the side walls the walls contains a structure of extruded elements, the structure of extruded elements contains an extruded element having a plan in the form of a wall in the form of a ring with the center of the annular extruded element, the center of the annular extension lennogo element is located above the center of the wall in the direction from the center to the upper wall of the household appliance. This allows, for example, to realize the technical advantage of effectively reducing vibrations of a working household appliance due to the construction of extruded elements, as well as giving the device an aesthetically pleasing appearance. This is especially important in cases where the side wall is not a standard square, but a rectangular shape.

A cabinet-shaped housing limits the interior of the appliance. In this interior of the cabinet-shaped case, a rotational axis of the drum is located, the rotational axis being located at a height of no extruded surface elements surrounded by an extruded annular element. Thus, the axis of rotation can be positioned above the center of the wall. Fluctuations in the household appliance are caused essentially by the rotation of the drum or the drive of the drum. Thus, by adapting the annular extruded element to the height position of the axis of rotation, it is possible to minimize the propagation of vibrations along the side wall. If the household appliance contains an oscillating system, which includes a drum, then the risk of shock of the oscillating system during operation is further reduced if the maximum deviations of the oscillating system occur in the side wall region without extruded elements surrounded by an annular extruded element. The possible risk of damage during transport is also prevented.

In one embodiment, the axis of rotation is located at the height of the center of the annular extruded element. This is advantageous if the maximum deviations of the oscillatory system fall on the height of the axis of rotation.

In a further embodiment, the axis of rotation is at some distance from the center of the annular extruded element, the annular extruded element having a radius and the indicated distance is less than the radius. The specified radius specifies the distance from the center of the annular extruded element to the edge of the annular extruded element facing its center. In particular, the axis of rotation is located at a height below the center of the annular extruded element. As a result, for example, a technical advantage is achieved consisting in the possibility of an additional increase in stiffness or improvement of modal characteristics due to the displacement of the extruded elements. This reduces the risk of shock of the oscillating system during operation and the risk of possible damage to the household appliance during transportation.

In particular, the height of the annular extruded element can be adapted to the design features of the components of the oscillatory system. Such components of the oscillatory system include, for example, a washing solution tank or a drum located in the tank. In particular, the washing solution tank may have a weld, and the height of the annular extruded element or the center of the annular extruded element can be adapted to the height position of the weld.

In order to use the accessible surface of the side wall of the household appliance, usually having a rectangular shape, at least two mutually parallel extruded elements are best located outside the annular extruded element and have the shape of a strip. If the household appliance is a washer, dryer or washer-dryer, then a drive or motor is usually located in the lower area of the cabinet-shaped cabinet. Thus, the vibrations created by the drive inside the household appliance can be particularly damped by arranging at least two mutually parallel extruded elements, while the annular extruded element allows the drum to be optimally and compactly positioned in a cabinet-shaped housing.

In addition, two mutually parallel extruded elements may be in the form of an arc. This design provides a particularly advantageous and efficient damping of vibrations caused by the drive.

Since, in particular, in the case of washing machines, at least one motor or drive is located in the lower region of the household appliance, two mutually parallel extruded elements are located below the annular extruded element in the direction from the annular extruded element to the lower side of the household appliance. In this case, it is possible to effectively take into account the vibrations caused by the drive in the lower area of the household appliance by arranging mutually parallel extruded elements directly at the height of the drive causing the vibrations.

In order to make best use of the available area of a substantially rectangular wall, the extruded element structure comprises a third extruded strip-shaped element located outside the annular extruded element. This improves the damping properties of the side wall and further increases the stiffness and improves the modal characteristics of the household appliance as a whole. Particularly advantageous is the option in which the third extruded element has the shape of an arcuate strip. Alternatively, the third extruded element in the form of a strip may be made straight, rectangular, sickle-shaped or other shape.

In order, in particular, to make the most efficient use of the area of the rectangular side walls and thereby maximize the damping properties of the side wall, the third extruded strip-shaped element is positioned relative to the annular extruded element so that it is opposite two mutually parallel extruded elements.

To control and effectively reduce the vibrational characteristics of household appliances, in particular washing machines at high speed and spin cycles at high speeds, the extruded element structure contains an additional annular extruded element located concentrically with the annular extruded element. The first and second annular extruded element may be in the form of a circle or oval.

In a particularly preferred embodiment, the extruded elements are bulges. In a particularly preferred embodiment, these bulges can be directed inward, but a variant with an outward direction is also possible. The implementation of the extruded elements in the form of bulges directed inward or outward showed particularly high stabilizing properties, and the use of the bulges makes it possible to easily and economically produce side walls, without taking into account restrictions on the damping efficiency or stability of the household appliance as a whole.
