Definitions

  • the invention relates to a household appliance with a closure element with a handle element.
  • a closure element can be a door, a flap or the like.
  • the movement between the opened or released state and the closed state can be rotational by pivoting or folding the closure element around a rotation axis, for example by means of hinges or the like, or translational by pulling or pushing along an axis. Combined movements are also possible using appropriate mechanisms.
  • a handle element is usually arranged on the front of the closure element, which faces the user, and can be grasped by the user with the hand or at least with the fingers in order to move the closure element.
  • Such handle elements can be designed as handles or as handgrips, in particular to be grasped around or grasped behind by the user, which enables the user to securely grasp and hold the handle element and can thereby enable or promote secure and defined guidance of the closure element during movement.
  • handle elements In addition to the technical function of being gripped and moved by the user, such handle elements should also be visually appealing or inconspicuous, since the handle elements are part of or attached to the closure element and are usually arranged in a visually exposed manner.
  • the handle elements can therefore have a strong influence on the external appearance of the closure element. This applies in particular to kitchen appliances and in particular to built-in kitchen appliances, where the closure element usually forms or takes up essentially or even completely the front.
  • Built-in kitchen appliances can also be raised above the ground and thus arranged at the user's eye level, which can further increase the user's attention to the appearance of the built-in kitchen appliance.
  • the handle element of a closure element can therefore have great optical and aesthetic significance.
  • an inner part can be designed to be technically functional as a holding part of the handle element and can be defined and fixedly mounted on the closure element in order to transmit the forces of the user's movement.
  • the inner part of the closure element can then be enclosed and covered at least in sections by an outer part as a decorative part of the handle element, so that only the outer part is essentially or completely visually perceived by the user and can be designed accordingly in an appealing, high-quality and aesthetic manner.
  • an outer part as a decorative part of the handle element, so that only the outer part is essentially or completely visually perceived by the user and can be designed accordingly in an appealing, high-quality and aesthetic manner.
  • Such a handle element is also described in the publication DE 10 2010 043 340 A1 revealed.
  • connection between the inner part and the outer part of the handle element of the closure element must also be fixed and at the same time visually appealing or not disruptive in order to achieve both goals and to ensure functions.
  • a gap forms between the inner part and the outer part of the handle element of the closure element at the contact points or on the contact surfaces, which should therefore also be visually appealing or inconspicuous.
  • gluing and locking are known to fasten the outer part to the inner part of the handle element of the closure element.
  • the disadvantage of bonding the outer part to the inner part of the handle element of the closure element is that when the gap is formed between the outer part and the inner part as components to be joined, there can be strong process fluctuations during bonding, which can result in an uneven gap. In this case, the gap or joint can also become larger when the later payload is applied. expand if the adhesive cannot withstand the stresses, at least in the long term. This could impair the visual impression for the user.
  • locking or locking connections between the outer part and the inner part of the handle element of the closure element is that this does not prevent the joined components from moving relative to one another. Locked components also tend to produce noise in the form of friction and clicking sounds during subsequent handling due to the play of the connected components, which the user finds annoying and can view as poor quality.
  • the outer part as a decorative element can also be attached to the inner part of the handle element of the closure element over a longer surface or over an angle contour and that both components can be positioned exactly relative to each other. If this cannot be achieved, this can lead to optical defects in the handle element of the closure element, as already mentioned.
  • the invention therefore addresses the problem of creating a household appliance with a closure element with a handle element, the handle element of which can be mounted on the closure element more easily, more quickly, more cost-effectively and/or more visually appealingly than previously known. This should be possible in particular for the assembly of an outer part of the handle element on an inner part of the handle element of the closure element. At least an alternative to the known possibilities should be created.
  • the invention relates to a household appliance, particularly preferably a kitchen appliance, most preferably a cooking appliance, with an interior with an access opening and with a closure element which is designed to be moved by a user by means of a handle element in order to close and open the access opening of the interior, wherein the handle element has at least one inner part which is fixedly connected to the closure element and at least one outer part which is fixedly connected to the inner part of the handle element.
  • the household appliance according to the invention is characterized in that the outer part of the handle element is connected to the inner part of the handle element by means of at least one connecting element, preferably by means of at least one screw, wherein the connecting element is guided through a through-opening of the inner part facing away from the outer part of the handle element and holds the outer part of the handle element by engaging in a blind hole, groove or undercut of the outer part.
  • the connecting element can enable any type of suitable mechanical connection between the outer part and the inner part of the handle element, which on the one hand should enable a secure hold and non-destructive separation and on the other hand cannot be seen by the user from the outside, i.e. from the side of the outer part of the handle element.
  • This can be done, for example, by means of a screw from the inside, which ends inside the outer part of the handle element and holds the outer part of the handle element to the inner part of the handle element by engaging in an internal thread of the blind hole of the outer part of the handle element. This makes it possible to achieve a durable but detachable and at the same time visually inconspicuous connection between the outer and inner parts of the handle element.
  • the front side of the closure element also has a through-opening, wherein the connecting element is guided through the through-opening of the closure element, facing away from the outer part of the handle element.
  • the outer part of the handle element and the inner part of the handle element - and thus the entire handle element - can be connected to the closure element in one step, which can reduce or keep the assembly effort to a minimum.
  • the outer part of the handle element is connected to the inner part of the handle element by means of a plurality of connecting elements, preferably by means of a plurality of screws, wherein each connecting element is guided through a respective through-opening of the inner part facing away from the outer part of the handle element and holds the outer part of the handle element by engaging in a blind hole in the outer part.
  • the outer part of the handle element is secured by means of at least one holding element, preferably by means of at least one pin, preferably by means of a plurality of parallel holding elements, preferably pins, perpendicular to the elongated extension of the connecting element, non-positively connected to the inner part of the handle element.
  • a pin is understood to be a simple machine element for connecting components or workpieces to one another.
  • the pin is designed as a single piece, ie integral, and is linearly elongated.
  • the pin can have any suitable shape or contour, but is preferably cylindrical.
  • connection can also be removed without causing any damage and can be re-established easily and quickly, for example to replace the outer part.
  • the use of a plurality of parallel mounting elements or pins can increase or improve the stability of the connection as well as the accuracy of the positioning.
  • the holding elements preferably pins, are arranged at equal distances from one another. This can increase or improve the stability of the connection and the accuracy of the positioning.
  • the holding element preferably the pin, preferably the holding elements, preferably the pins, are made of solid material or are thin-walled.
  • the use of solid material can increase the stability and durability of the connection.
  • the use of thin-walled hollow material can enable a certain spring-elastic compressibility perpendicular to the longitudinal extension direction of the holding element or pin, which can increase the frictional connection.
  • the outer part of the handle element and the inner part of the handle element have opposing holding element receptacles, preferably pin holes, wherein the, preferably one pair of corresponding holding element receptacles of the handle element together receive the, preferably one, holding element, preferably the, preferably one, pin, in a force-fitting manner.
  • This can represent one possibility for concrete implementation.
  • the outer part of the handle element and the inner part of the handle element have mutually opposite stop edges along the elongated extension of the holding element, preferably pin, preferably the holding elements, preferably pins, so that the outer part of the handle element projects beyond the inner part of the handle element along the elongated extension of the holding element, preferably pin, preferably the holding elements, preferably pins, at least in sections, preferably completely.
  • the movement of the connection or joining by means of the pin or pins can be limited by the contact of the stop edge of the outer part of the handle element with the stop edge of the inner part of the handle element.
  • the outer part of the handle element can be shaped in this way such that the outer part of the handle element projects beyond the inner part of the handle element at least partially to completely past the edge of the inner part of the handle element and thus covers it. This can create a uniform surface, especially towards the user, which can be more visually appealing to the user than seeing the inside of the handle element.
  • the outer part of the handle element projects beyond the inner part of the handle element at least along the transverse axis, preferably also along the longitudinal axis.
  • the outer part of the handle element can close off the handle element on the outside and create a uniform and closed appearance, which can be more visually appealing for the user than seeing the inner part of the handle element.
  • the outer part of the handle element is an outwardly visible decorative element of the handle element. This can improve the visual impression and increase the optical design options.
  • the outer part of the handle element and the inner part of the handle element form a defined joint between them. This can improve the visual impression.
  • the grip element is curved in shape so that the user can grip it with at least one finger, preferably with all fingers, at least in sections, preferably completely and continuously. This can make it easier for the user to move the closure element by gripping and pulling or pressing the grip element.
  • the grip element extends substantially horizontally. This can make gripping easier for the user. This can be particularly for closure elements in the form of flaps which are movably mounted on the lower edge.
  • the present invention also relates to a closure element with at least one handle element for use in a household appliance as described above. This makes it possible to create a closure element for implementing a household appliance as described above.
