Definitions

  • the invention relates to a household appliance with a door handle according to the preamble of claim 1 and a method for producing such a door handle according to the preamble of claim 10.
  • this has a door handle, which can be attached as a design element on the door front of the door and can be composed of several parts of plastic and / or metal elements.
  • the door handle consists of a vertically arranged handle which is inserted as an elongated profile part at its upper and lower end faces between handle holders which are mounted on the appliance door.
  • the handle is here a hollow cylindrical handle tube with a circular cross section, which is constantly constant in the axial direction of the handle tube.
  • the object of the invention is to provide a household appliance and a method for producing such a household appliance, in which the handle feel of the door handle can be improved in geometrically and manufacturing technology simple manner.
  • a door handle which is mountable to a door of a household appliance.
  • the door handle has a handle that can be grasped by the user, and at least one grip holder, which connects the handle to the door.
  • the invention is based on the fact that in the household appliance sector grips with a round cross-sectional profile with respect to the haptic perception of the user are not perceived as pleasant. to Simple increase of the grip haptic therefore a profiled part with a non-circular cross-sectional profile is used as a handle instead of a profile part with a round cross-sectional profile.
  • the feel of the grip is improved by the fact that the cross-sectional profile of the profile strip that is constant in the longitudinal direction varies at least in sections in its rotational angle position.
  • the domestic appliance according to the invention is used for housekeeping and can be, for example, a refrigerator, such as a refrigerator, a freezer, a freezer, a wine storage cabinet or a fridge freezer.
  • the non-circular cross-sectional profile of the profile part may have at least one running in the longitudinal direction of the outer edge, which can be engaged behind by the fingers of the user.
  • the outer edge of the profile part can pull in the longitudinal direction at least partially helically along a helical line about the longitudinal axis of the profile part.
  • the elongated handle may be mounted at its two front ends each on a handle holder, whereby an open penetration area for the user is provided between the door front, the elongated handle and the two upper and lower handle holders. It is preferred if the rotational angle position of the cross-sectional profile of the profile part over the entire free handle length, that changes between the two handle holders in a predetermined manner.
  • the change in the rotational angle position of the cross-sectional profile can preferably take place uniformly in the longitudinal direction of the profile part.
  • the angular position of the cross-sectional profile can change.
  • the profile part can be made of a solid material or a hollow material.
  • a hollow cylindrical profile part has proven with a constant wall thickness in the circumferential direction.
  • the varying in the longitudinal extent of the angular position of the cross-sectional profile can be achieved in different types of production.
  • the special contour of the profile part can be produced by hydroforming in which the profile part can be injected as an internal gas pressure part.
  • a production technically complex hydroforming system is required.
  • the profile part is initially provided in a basic design without a, varying along the handle longitudinal axis axis of rotation of the cross-sectional profile.
  • the angular position of the cross-sectional profile in the longitudinal axis can then be changed in a further manufacturing step by twisting or twisting, in which the profile part is rotated in opposite directions at two spaced locations under plastic deformation.
  • twisting plastic deformation also has the advantage that in the plastic or metal material of the handle can lead to a structural change in the material.
  • the structural change can further increase the material stiffness of the grip.
  • This manufacturing method has the additional advantage that the profile part can be cut as a blank from a continuous strand or strand part made by extrusion with an arbitrarily specifiable cut length. Depending on the intended handle height thus the blank length can be varied.
  • the subsequently performed twisting or twisting can be done in a technically easy to perform clamping device in which the final outer contour of the elongated handle can be made.
  • the two end pieces of the cut profile part can each be clamped in opposite tool approaches of the clamping device and rotated in opposite directions of rotation against each other or twisted until the predetermined angle of rotation between the two end pieces of the elongated profile part is adjusted by plastic deformation.
  • a profile geometry has proven to be advantageous in which, viewed in cross-section, a semicircular circle segment with a given radius transitions approximately at right angles into two wall segments angled inward therefrom.
  • the wall segments may be approximately isosceles and be connected at an obtuse angle to each other at a transition edge.
  • One of these wall segments may preferably be slightly outwardly swung while the other wall segment may be slightly curved inward, resulting in a groove in the direction of longitudinal groove-shaped finger-trough for the user's fingertips.
  • the two wall segments can be in the
  • Fig. 1 is shown in a partial view from the front a refrigeration device with a about a vertical pivot axis S laterally hinged to the device body of the refrigerator appliance door 1.
  • the appliance door 1 has in the device side direction opposite to the pivot axis S a door handle 3.
  • the door handle 3 is constructed in several parts of an upper and a lower handle holder 5 and an intermediate handle 7, which in the present case is a hollow cylindrical handle tube made of a plastic material. Alternatively, the handle tube can also be made of metal.
  • the upper and lower handle holder 5 are in screw 6 with the side edge 8 of the door 1.
  • the hollow cylindrical handle tube 7 has a non-circular Cross-sectional profile, according to the Fig. 3 consists of a semicircular circular segment 9 with a circular radius r.
  • the circular segment 9 merges into two wall segments 13, 15 in the circumferential direction, in each case approximately at right angles to the outer edges 11.
  • the two wall segments 13, 15 are made approximately isosceles and connected to each other opposite the more acute-angled outer edges 11 at an obtuse transitional edge 17. It is in the Fig. 3 shown upper wall segment 13 slightly outwardly swung while in the Fig.
  • the thus configured special non-circular cross-sectional profile of the handle tube 7 is according to the Fig. 2 along the entire longitudinal direction x of the handle tube 7 made constant. Only the angular position ⁇ of the otherwise constant cross-sectional profile changes over the entire handle length I in a uniform manner. This results in a geometrically simple outer contour of the handle tube 7, which allows a comfortable grip feel and a comfortable finger guidance when gripping the grip tube 7.
  • plug projections of the upper and lower handle holder 5 are inserted into the front ends 23 of the handle tube 7.
  • the two front ends 23 of the handle tube 7 are in the Fig. 1 and 2 extended in the longitudinal direction x with wall segments 25 which cover a front-side end wall of the upper / lower handle holder 5 visible.
  • the handle tube 7 is a blank part, which is cut from an elongated endless strand 21 in a production direction F with a predetermined cutting length a.
  • the endless strand 21 is designed in the production direction F with a constant cross-sectional profile, wherein the rotational angle position in the production direction F is still constant.
  • the blank part is placed in a clamping device, not shown further, in which the blank part is fixed at its front-side opposite ends 23.
  • the two end-side ends 23 of the handle tube 7 are then rotated or twisted in opposite directions of rotation under plastic deformation of the blank part.
  • the rotational angle position ⁇ of the manufacturing technology in a simple manner Cross-sectional profile over the entire handle length I between the two front-side handle tube ends 23 changed with a uniform pitch.
  • the profiled part thus produced is assembled on the front side with the two handle holders 5 and this component assembly is brought into screw connection 6 with the appliance door 1.
