[0001] The present invention refers to a washing machine for washing laundry, comprising
a body with an access opening for loading/unloading laundry to be washed, and in the
lower section thereof which is intended for mounting the washing machine on the surface,
a plurality of vertically adjustable supports connected to said body.
[0002] Vibrations caused in operation of a washing machine are transmitted to the body and
exert negative impact not only to the loaded parts of the body but to the stability
of the washing machine as well. In particular, it is important for the body to be
formed in a manner that the vibration forces transmitted to the supports of the washing
machine and the surface act as less as possible in horizontal direction to prevent
the washing machine to be displaced on the surface. In order to avoid said problems,
known solutions provide reinforcement of the body in the area of supports by means
of additional elements. Moreover, known are solutions that try to increase the stiffness
of the body by means of plastic deformation and, respectively, deep drawing, and the
folds in the corners of the body of the machine at the places where supports are attached.
Due to potentially uneven surface and limited mounting stability, the washing machines
are provided as a rule with at least one vertically adjustable support. Said support
is formed with a base cooperating with the surface on which the washing machine is
mounted. A threaded shank projects from said base being screwed from the bottom side
to the body of the washing machine. Drawback of such solutions is relatively thin
and flexible material the body is produced of, thus, resulting in a local deflection
of said material and in transmission of unwanted vibrations to the surface.
[0003] It is the object of the present invention to create a washing machine of the aforementioned
kind in which a body in the vicinity of supports is as rigid as possible, thus, preventing
transfer of the vibrations to the ground.
[0004] According to the present invention, the object as set above is solved in a manner,
that an input of a plastic deformation, such as a deep drawing, is provided in the
section of the body bottom in the horizontal extension thereof, wherein at the side
of said plastic deformation which is averted from the surface on which a washing machine
is mounted, there is provided a through hole the centre line thereof lies coaxially
with the centre line of a support of the washing machine and, respectively, with the
centre line of a threaded shank of said support. Said through hole preferably comprises
greater diameter than is the diameter of said threaded shank.
[0005] The invention will be more readily understood on reading the following description
of a non-limiting embodiment and with reference to the accompanying drawings

- Fig. 2

[0006] A washing machine according to the invention comprises a body consisting of a U shaped
casing 1, and a front wall 2 comprising an opening 3 for loading/unloading laundry
to be washed. Said front wall 2 is associated with said casing 1, for example by means
of a spot welding. Said casing 1 of the body and, respectively, the front wall 2 are
formed at the bottom end thereof which, with the normally mounted washing machine,
faces the surface the washing machine is mounted on, with a first horizontal fold
4 and with a second horizontal fold 5 both projecting to the interior of the washing
machine.
[0007] A flat reinforcing element 10 is attached to each corner section 6, 7, 8, 9 of the
horizontal fold 4; 5 which cooperates with the surface the washing machine is mounted
on. Said reinforcing element 10 is formed with a flange 11 comprising a threaded through
hole into which a support 13 of the washing machine is screwed in by means of a threaded
shank 12. In order to act on said support 13, the latter is formed at the side which
cooperates with said surface with at least one, and preferably with two polygonal
sections 14, 15 to be engaged with the tool by means of which a user may act to the
support 13. Each horizontal fold 4; 5 is formed in the area of said flange 11 of the
reinforcing element 10 with a through hole in order to allow free passage of the threaded
shank 12 of the support 13 when the latter is installed and/or vertically adjusted.
[0008] In order to increase rigidity of the washing machine and, as a result, decrease vibrations
thereof, at least one of horizontal folds 4; 5 of the casing 1 and, respectively,
the front wall 2 is formed at least partially and/or at least piecewise continuously
with a reinforcing elevation 16 extending in longitudinal direction of the fold 4;
5. Said elevation 16 is made by means of plastic deformation, such as by bending the
fold 4; 5 or by input of a deep draw into the fold 4; 5. According to the preferred
embodiment, said elevation 16 is formed uninterrupted and essentially over the entire
length of thr fold 4; 5, and in direction away from said surface on which the washing
machine is mounted on. Said elevation 16 is formed in the area of the arrangement
of the support 13 with a through hole 17 to allow passage for the threaded shank 12
of the support 13. It is provided for according to the present invention, that with
the assembled body of the washing machine each horizontal fold 4; 5 of the casing
1 and, respectively, of the front wall 2 which is formed with said elevation 16 rests
on the horizontal fold 4; 5 which is formed without the elevation 16.
[0009] With the present embodiment shown in accompanied drawings, said elevation is formed
on the second horizontal fold 5 of the front wall 2. Therefore, with the assembled
body the second horizontal fold 5 of the front wall 2 rests on said first horizontal
fold 4 of the casing 1.
[0010] Furthermore, it is possible according to one of embodiments, that said flange 11
of the reinforcing element 10 extends to the area of said through hole 17 of the elevation
16 and is there tightly connected to said elevation 16.
