Description

The invention relates to a device for a household appliance with a container for a liquid or powdery medium.

There are household appliances, such as a steam oven or a Dampfgargerät or even coffee machines such as a coffee machine, which have devices in which a container is provided for receiving water or coffee powder. During operation of a Dampfgargeräts the water is then evaporated in the container and passed into the cooking chamber to prepare a food. However, the water can also be evaporated only in the oven itself. In a fully automatic coffee machine, the powder is mixed with water and the coffee is brewed to prepare the coffee.

Such known devices are often relatively bulky, especially with regard to the container in the motion control and can be spreader. This can lead to the fact that during insertion or withdrawal, the powder or the liquid medium still contained therein, can spill or sprinkle out and thereby impurities arise.

It is an object of the present invention to provide a device for a household appliance, in which these disadvantages mentioned can be eliminated.

This object is achieved by a device having the features of claim 1.

A device according to the invention for a household appliance comprises a container which is designed to receive liquid or powdered medium. The device further comprises a receptacle for the container, which is designed separately for the container. On opposite sides of the receiving shaft spring elements are arranged, each with at least one Slide sliding nub into the receiving shaft and abut the container and its motion guide during insertion of the container into the receiving shaft. By such a configuration, the insertion and withdrawal of the container in or out of the receiving shaft can be performed in a special way. A spreading or jamming can be avoided.

By Gleitnoppen a particularly simple and sliding motion control can be realized at least in the translational direction. In addition, the space can remain unchanged by the specific arrangement of the spring elements outside the receiving shaft and the interior of the receiving slot and the spring elements are not the motion control of the container in the way. By Gleitnoppen this motion control is particularly favored.

Preferably, it is provided that the spring elements are formed like a clip and can be attached to outer sides of the receiving shaft, in particular the outer sides are encompassing infectable. Such a non-destructive reversible releasable attachment option also allows the replacement of these spring elements or the accessibility for cleaning or assembly purposes. Due to the specific shape of the spring elements, they can be arranged on the receiving shaft outside in a particularly mechanically stable manner. In particular, they are so high that they can be positioned adjacent to both the floor and on the ceiling of the receiving shaft a particularly mechanically stable attachment can be achieved. In particular, this can also be an undesirable tilting or moving relative to the receiving shaft can be prevented when the container is inserted into the receiving shaft in the horizontal direction.

Preferably, it is provided that the sliding knobs are cylindrical pins which extend horizontally through in each case a slot in an outer side of the receiving shaft inwards. By such a configuration, an additional position holder of a spring element is achieved when it is arranged on the outside of the receiving shaft, in particular infected. In addition, the sliding knobs are held fixed in position by a particularly accurate fit introduction into such a continuous slot.

Preferably, the sliding nubs are resilient and arranged on the spring elements. Thereby, a certain relative mobility can be created, so that on the one hand a particularly stable application to the container can be achieved, on the other hand, a particularly reliable uniform motion control is achieved in particular in the translational direction. Due to the resilient arrangement of the sliding knobs, a compensation movement can also be made possible, whereby spreading or tilting of the container during insertion into the receiving shaft can be prevented in a particularly advantageous manner.

Preferably, it is provided that a spring element has two S-shaped winding and symmetrically arranged to a vertical axis of the spring element Gleitnoppenhalter. By means of such an arrangement and shaping, the abovementioned relative mobility of the sliding knobs is achieved particularly advantageously.

Preferably, the Gleitnoppenhalter are relatively movable, in particular resilient, arranged to each other.

In particular, it is provided that each spring element has at least two sliding knobs, which are arranged one behind the other in the longitudinal direction of the receiving shaft. This is a particularly noteworthy embodiment, since in addition to a very favorable translational motion control of the container in the receiving shaft at the same time also preventing rotational undesirable movements of the container during insertion or withdrawal in or out of the receiving shaft is achieved.

It is preferably provided that at least one outer side of a side wall of the container is formed at least one Arretierungsvertiefung, which is designed to receive a Gleitnoppe. By such an advantageous embodiment, the container can be fixed in position relative to the receiving shaft in at least one position. In particular, this is the case in the inserted end position, so that an undesired withdrawal or slipping out of this end position in the receiving shaft can be prevented. In addition, at least one further locking position can be achieved in the at least partially extended state of the container in the receiving shaft. This can also provide accessibility to the Container can be achieved in the partially extended state and in this position-fixed state, a refill of the medium can be easily made possible.

Preferably, a locking recess is formed as a vertically extending locking channel.

Preferably, it is provided that the opposite side walls of the container have outwardly projecting webs, abut the underside of the slide nubs during insertion of the container in and during withdrawal of the container from the receiving shaft. Preferably, these outwardly projecting webs are oriented virtually horizontally and formed at the upper edge of the vertical side walls. As a result, a certain vertical position support of the container during insertion into the receiving shaft or when pulling out of the receiving shaft is virtually guaranteed.

It is preferably provided that the device is arranged in a steam cooking appliance and the medium is liquid, in particular water.

However, it can also be provided that the device is arranged in a coffee machine. For example, then the medium may be powdery, in particular coffee powder. However, it can also be provided that such a device is arranged in a coffee machine and for receiving the water, which is then mixed with the coffee powder and generates the coffee is provided.

Preferably, the at least two spring elements are of identical design and positioned with respect to the longitudinal axis of the receiving shaft at the same length level on opposite side.

It can be provided that each spring element has at least two sliding nubs, which are arranged one behind the other in the longitudinal direction, and at least two locking recesses are arranged on each vertical side wall of the container. By correctly adjusting the position of the spring elements and the Arretierungsvertiefungen a desired locking position can be formed. In particular, in that each spring element preferably has two sliding nubs, even two different locking points can be provided. By suitable distance dimensioning of Gleitnoppen depending on the device type of the domestic appliance then the appropriate locking positions device type individually trained and made available.

Preferably, a spring element is integrally formed. It is made in particular of plastic, whereby it is relatively inexpensive to produce, and moreover is very easy. By such a design of a spring element, on the one hand, a component saving can be achieved and, moreover, the functional principle can be reduced with regard to the complexity and the interaction of several components. In addition, unwanted position tolerances that occur in multi-part motion guide devices can be avoided.

In the figures, identical or functionally identical elements are provided with the same reference numerals.

In Fig. 1 a domestic appliance 1 is shown, which is designed as a steam oven. The domestic appliance 1 comprises cooking zones 2, 3, 4 and 5 and a cooking chamber 6 which can be closed by a door 7. On an outer side of the door 7, a handle 8 is formed. In the embodiment above the door 7, an operating device 9 is arranged, which is positioned in a control panel 10. The operating device 9 comprises, in position, number and size, exemplary operating elements 11 and 12 as well as a display unit 13.

Positionally only by way of example is provided in the exemplary embodiment that in the control panel 10 adjacent to the operating device 9, a device 14 with a container 15 (FIG. Fig. 2 ) for receiving liquid medium, in particular water, is formed. The water is evaporated during operation of the domestic appliance 1 and provided in the cooking chamber 6 in order to prepare there the introduced food.

As seen from the presentation Fig. 1 can be seen, the device 14 is front accessible and operable and the container 15 can in the horizontal direction from a arranged in the control panel 10 and integrated receiving shaft 16 (FIG. Fig. 2 ) are pulled out and inserted.

For further explanation is now on Fig. 2 directed. The device 14 comprises in addition to the already mentioned container 15 and the receiving shaft 16, both preferably integrally formed plastic parts are two spring elements 17 and 18. The spring elements 17 and 18 are each also one-piece components and made of plastic. In the illustration according to Fig. 2 it can be seen that the two spring elements 17 and 18 on opposite vertical side walls 19 and 20 of the receiving shaft 16 are externally attachable. The spring elements 17 and 18 can be non-destructively and reversibly released and replaced. In the illustration according to Fig. 2 It can be seen that the spring element 17 is plugged into the outer side 20 and thereby surrounds the receiving shaft 16 like a clamp. The spring element 17 is therefore also on the outside, in particular on a ceiling wall 21 and a bottom 22 of the receiving shaft 16.

In contrast, for further explanation in Fig. 2 the spring element 18 is removed from the receiving shaft 16. It can be seen that in the side wall 19, two vertical elongated holes 23 and 24 are formed extending parallel and quasi as continuous slots. These are arranged one behind the other in the longitudinal direction of the longitudinal axis A. When assembled, the in Fig. 2 not yet recognizable Gleitnoppen the spring elements 17 and 18 through this in each case on the side walls 19 and 20 pairwise formed slots 23 and 24 in the interior 25 of the receiving shaft 16th

When inserting the container 15 then contact these Gleitnoppen vertical side walls 26 and 27 of the container 15, so that this is held translationally and rotationally guided.

In Fig. 3 is shown in a perspective view of the container 15. It can be seen that on the vertical side wall 26 in the rear region two locking recesses 28 and 29 are formed as vertical channels which extend directly next to each other in parallel. The locking recesses 28 and 29 extend in the embodiment over the entire height of the side wall 26. On the opposite side wall 27 are considered with respect to the longitudinal axis A at the same length level according to two locking recesses formed.

In this Arretierungsvertiefungen 28 and 29 can engage a position of the container 15 relative to the receiving shaft 16, a Gleitnoppe the spring element 18.

In Fig. 4 is an embodiment of the spring element 18 is shown in a first perspective view. The spring element 17 is designed analogously thereto. It can be seen that the spring element 18 has two S-shaped spiral slide holders 30 and 31. These are arranged symmetrically with respect to a vertical axis B. At the upper ends and the lower ends of these S-shaped Gleitnoppenhalter 30 and 31 horizontally protruding clip bracket 32 and 33 are formed. With these, as shown in Fig. 2 ensures the concern and clip-like holding on the ceiling wall 21 and the bottom 22. In addition, two latching elements 34, 35 and 36 and 37 are formed in these brackets 32 and 33, respectively. By means of these, the latching attachment to the receiving shaft 16 can be achieved.

Furthermore, it can be seen that the two already mentioned sliding nubs 38 and 39 are formed approximately in the middle of the S-shaped profile. These are arranged on slide bars 40 and 41, wherein the slide bars 40 and 41 at their upper ends arcuate cranks 42 and 43 have.

In Fig. 5 the spring element 18 is shown in a further perspective view, which compared to the representation in Fig. 4 the inverted view shows.

In Fig. 6 is shown in a perspective top view of the container 15 with the oppositely disposed spring elements 17 and 18, which bear against the side wall 26 of the container 15 in terms of movement with respect to the engagement of the sliding nubs 38 and 39.

In particular, it is provided that at the upper edges of the side walls 26 and 27 outwardly projecting webs 44 and 45, which preferably extend over the entire length of the side walls 26 and 27 are formed. These upper edges, and in particular the webs 44 and 45, are encompassed by the bends 42 and 43. In addition, the sliding nubs 38 and 39 are preferably located on the underside of the web 44. By such a configuration, the container 15 can be guided horizontally position fixing in the vertical direction.

However, it can also be provided that the webs 44 and 45 are not present. This also makes it possible to achieve such a movement guidance, since the cranks 42 and 43 also engage over this upper edge of the side walls 26 and 27.

In Fig. 6 serving for clarity, the receiving shaft 16 is removed, but on which the spring elements 17 and 18 as shown in FIG Fig. 1 are attached.

In Fig. 7 is the in Fig. 6 shown construction of said components shown in a further perspective view. It can be seen that the sliding knob 38 is engaged in the locking recess 29. Accordingly, the Gleitnoppe the opposite spring element 17 is engaged in the corresponding locking recess.

As can be seen in the figures, a docking stub 47 is formed on a rear wall 46, which is coupled in the inserted state of the container 15 in the receiving shaft 16 with a docking area of a conduit system for guiding the water.

In particular, the movement guide and centering is achieved in that the sliding nubs 38 and 39 of the two spring elements 17 and 18 are tensioned during insertion of the container 15 by resilient knob suspension. The container 15 is thus clamped by the spring elements 17 and 18 and is thus aligned centrally in the receiving shaft 16. Characterized in that at least two sliding nubs 38 and 39 are arranged on each spring element 17 and 18, the container 15 is not only translationally but also rotationally fixed when a corresponding movement guide is relative to the receiving shaft 16.
