Definitions
- the invention relates to a damper, in particular for washing machines with a spin cycle.
- DE 22 04 325 C2 discloses a drum-type washing machine with struts or friction dampers for damping the vibrations of the washing unit. These each have a housing with a plunger slidably guided therein. To determine the insertion depth of the plunger, the plunger is hollow with a permanent magnet. Arranged in front of the housing of the damper in the direction of extension of the tappet is an annular coil which surrounds the tappet and is capable of detecting the position of the permanent magnet in the annular coil.
- the known device makes it possible to determine a specific predetermined critical insertion depth of the ram and to interrupt the spin cycle, for example, due to particularly strong vibrations. The result is therefore only digital. A disadvantage of this arrangement is that the position of the plunger cannot be determined continuously.
- the coil arranged upstream of the housing makes the overall arrangement longer. Another disadvantage is that it is not possible to determine the payload of the washing unit, since, due to the high static friction between the friction lining and the housing, the insertion depth is not a measure of the payload.
- the invention has for its object to provide a damper with a housing and a plunger slidably guided therein, in which the insertion depth of the plunger into the housing is as simple as possible can be determined and from this the insertion force acting on the ram can be determined.
- the object is solved by the features of claim 1.
- the essence of the invention is that a measuring element is connected to the housing and the plunger, the relative position of which is determined by electrical interaction, the plunger having an essentially frictionless idle stroke over part of the insertion depth. This enables e.g. B. to measure the weight of dry laundry and water at rest and / or to detect dynamic imbalances during operation.

- the drum washing machine according to FIGS. 3 and 4 differs from that according to FIGS. 1 and 2 in that the washing unit 2 is suspended from the machine housing 8 by means of helical tension springs 19.
- the Tension springs 19 are attached to eyes 20 on the one hand, which are attached in the upper area of the washing unit 2. On the other hand, they are suspended from eyelets 21 which are formed on the cover plate 22 of the washing machine housing 8.
- two friction dampers 23, which are described in more detail below, are attached in the center in the longitudinal direction and are connected to the machine frame 7.

- the pivot axis 35 of which, like the pivot axis 32, intersects the central longitudinal axis 25 perpendicularly. With this joint sleeve 34, the friction damper 23 is attached to a bearing 31 on the machine frame 7 so that the pivot axis 35 also runs parallel to the drum axis 1.
- a damping piston 38 is provided which has an annular groove 39 which is delimited in the longitudinal direction by annular stops 40, 41 which are integral with the damping piston 38 are trained.
- a ring-cylindrical damping ring 42 is arranged, which has an annular groove 43 on the outer circumference side, in which a friction damping coating 44 is provided.
- the damping ring 42 can be displaced in the annular groove 39 approximately without friction relative to the damping piston 38.
- the friction-damping lining 44 abuts the inside 45 of the housing 11.

- the strut 5 has a tappet position measuring device for detecting the insertion depth T of the tappet 13 in the housing 11.
- the measuring device has an annular-cylindrical sensor 52 which is fastened to the end of the damping piston 38 lying in the insertion direction 49 coaxially to the central longitudinal axis 12.
- the encoder 52 is made of metal, in particular iron or another ferritic material.
- the housing 11 consists of a magnetically permeable, in particular non-metallic material.
- the measuring device also has a coil unit 53 which, in the case shown in FIG. 5, consists of two coils 54 and 55 connected in series. The coils 54, 55 are connected to an evaluation unit 57 via electrical connecting lines 56.
- the spools- Unit 53 can in particular consist of one or two coils arranged adjacent to one another and surrounding the housing 11 in a ring-cylindrical manner.
- the coil unit 53 extends in the longitudinal direction, in particular at least over the length that is covered by the encoder 52 at the maximum insertion depth T of the plunger 13.
- the measuring device is a so-called inductive displacement transducer.
- the inductance is changed by inserting the encoder 52 into the interior of the coil 54.
- the inductance of the coil 54 is evaluated on a quarter bridge which is generally known in electrical engineering.
- the advantage of this arrangement is the completely simple structure. It is disadvantageous that changes in the insertion depth T are proportional to the change in inductance only in a narrow area around the operating point of a given insertion depth T.
- the measuring device is a so-called differential choke.
- An electrical signal is applied to the connecting lines 56 or tapped from them.
- By moving the encoder 52 in the interior of the coils 54, 55, their inductance is changed. Over approximately 80% of the length of the coils 54, 55 there is essentially a linear relationship between a change in the insertion depth T and the inductance.
- the evaluation of the insertion depth T via the change in inductance presupposes that the transmitter 52 consists of a ferromagnetic material, for example iron / steel. If an evaluation of the input thrust depth occurs via an eddy current effect, then the encoder 52 should consist of a non-ferromagnetic, but electrically conductive material, for example aluminum.
- the washing unit 2 is first loaded with laundry.
- the plunger 13 sinks into the housing 11 from the initial position shown in FIG. 5, so that the insertion depth T is increased.

- the plunger 13 thus has an idle stroke.
- the change ⁇ T in the insertion depth T is substantially proportional to the insertion force acting on the tappet 13, so that the weight of the laundry loaded is measured by measuring the change ⁇ T in the insertion depth T of the spring struts 5 of the washing machine can.
- the insertion force can be calculated via the spring constant of the spring 15 and the change ⁇ T.
- the evaluation unit 57 determines the payload mass of the washing unit 2 and any imbalance that may be present.
- the washing unit 2 vibrates, the amplitude of which is so great, that the damping ring 42 alternately in hit with the stops 40 and 41, so that the movement of the plunger 13 is damped by the friction-damping coating 44.
- the amplitude of the vibrations can be determined at any time by measuring the insertion depth T. If the amplitudes of the vibrations become too large, the spin speed can be reduced or the spin process can be stopped based on signals from the evaluation unit 57. It is possible in the drum washing machine described in the introduction to provide only one of the spring struts 5 with a tappet position measuring device. The other spring strut 5 can be designed in a commercial manner.
- a second embodiment of the spring strut 5 ' is described below with reference to FIG. 6. Identical parts are given the same reference numerals as for the strut 5 according to the first embodiment, to the description of which reference is hereby made.
