Definitions

  • a household appliance according to the invention is characterized in that at least one pivot arm is arranged on the body and that at least one slotted guide is connected to the front panel or is formed thereon, wherein the storage container is coupled to a free end of the pivot arm on the one hand and is guided in the slotted guide on the other hand.
  • the front panel as a flap that can be hinged or pivoted on the body.
  • the household appliance has a protective covering which is attached to the storage container and extends downward toward the front panel on at least one side of the storage container.
  • the protective covering may be of telescopic design, for example, and may be raised or extended with the storage container.
  • the protective covering prevents objects or body parts from entering a gap between the storage container and the front panel or between other components of the arrangement, at least one of which is moved.
  • the protective covering reduces a risk of entrapment by the moving components.
  • FIGS. 1 a - f show an isometric representation of a household appliance in a first exemplary embodiment at various stages of a storage container movement sequence
  • FIGS. 5 a, b each show a sectional drawing of a household appliance in a second exemplary embodiment
  • FIGS. 7 a, b each show a sectional view with detailed enlargement of a further exemplary embodiment of a household appliance with a retraction lock of the pull-out guide.
  • FIGS. 1 a - f show a first exemplary embodiment of a household appliance 1 in each case in an isometric representation in various states of movement of a storage container 41 .
  • FIGS. 2 a - f and 3 a - f show the household appliance 1 in various vertical sections to the same states of movement of the storage container 41 in each case.
  • FIG. 4 shows components of the household appliance 1 in an isometric exploded view.
  • the household appliance 1 has a body 2 with side walls 21 and two or more floors 22 .
  • a rear wall is not shown for reasons of clarity.
  • the household appliance 1 may be, for example, a refrigerator or freezer. As such, it usually has a multi-shell insulating body and technical cooling devices. For reasons of clarity, these are not shown in the illustrations of this application.
  • the representation of the body 2 is to be regarded in that sense as a purely schematic representation.
  • the body 2 has forward-facing openings, one of which is closed by a front panel 31 ( FIG. 1 a ).
  • the front panel 31 is part of a front panel arrangement 3 , which also comprises a pull-out guide 32 on which the front panel 31 is guided and through which the front panel 31 can be pulled out of the body 2 .
  • a connection of the front panel 31 with the pull-out guide is realized by lateral frame elements 33 .
  • the front panel arrangement 3 thus represents a drawer element which, however, unlike a drawer for example, does not require a base.
  • the entire movement sequence i.e., also the extension of the thrust element, is driven by a drive arrangement 5 , which is visible for example in the sequences of FIGS. 2 a - f and 3 a - f in the sectional views.
  • the drive arrangement 5 has a drive unit 51 comprising an electric motor with a downstream gear unit.
  • the drive unit 51 is controlled by a control device (not visible here) that is controlled by the release device.
  • the release device may be, for example, a manually operable pushbutton arranged at a convenient reach height on the household appliance 1 .
  • remote triggering can also be performed, for example wirelessly via a radio switch coupled to the control device, which can also be a mobile terminal, for example a cellphone of the user.
  • a radio switch coupled to the control device, which can also be a mobile terminal, for example a cellphone of the user.
  • Touch- or proximity-sensitive switches and/or voice- or gesture-controlled switches may also be used.
  • the drive unit 51 provides a rotary motion which, in the example shown, is transmitted via an output gear 52 and a belt 53 , in particular a toothed belt, to a drive gear 54 which is connected in a rotationally fixed manner to a pivot axis 45 .
  • the pivot axis 45 extends transversely across the entire width of the body 2 and is rotatably mounted thereon in pivot bearings 46 .
  • the pivot bearings 46 are mounted on the outside of the shown body 2 , which is a possibility, in particular, if the shown body 2 has an outer covering not shown here. In other cases, the pivot bearing 46 may also be arranged in a wall of the body 2 or on the inside thereof.
  • Two pivot arms 44 are coupled in a rotationally fixed manner to the pivot axis 45 , each of which is hinged to the outside of the storage container 41 in its lower area.
  • the drive gear 54 is positioned approximately centrally on the pivot axis 45 .
  • This can be implemented differently in alternative designs of a pivot arrangement 4 , to which the storage container 41 , the pivot axis 45 , the pivot bearings 46 , and the pivot arms 44 can be assigned.
  • the coupling of the drive arrangement 5 to the pivot axis 45 can be implemented alternatively.
  • a transmission can also take place with a push rod to the pivot arms 44 directly or a further pivot lever arranged on the pivot axis 45 .
  • a drive unit 5 that provides a rotary motion a drive unit that provides a linear motion at its output member can also be used.
  • the pivot axis 45 is positioned in a front and upper region of the body 2 relative to the region in which the storage container 41 is positioned within the body 2 .
  • the free end of the pivot arm 44 is supported in a combined sliding and pivoting guide 42 . Due to this bearing arrangement, a pivoting movement of the pivot arms 44 is transferred into a combined pivoting and lifting movement of the storage container 41 , wherein initially there is a certain degree of freedom for the composition of these movements at the storage container 41 .
  • at least one further guide of the storage container 41 relative to the body 2 is provided.
  • a first of these further guides is provided by a coupling between the storage container 41 and the front panel arrangement 3 .
  • a slotted guide 34 is formed for the purpose as part of the front panel arrangement 3 , in which guide means 43 of the storage container 41 move in a guided manner.
  • the slotted guide 34 is clearly shown in FIGS. 3 e and f , in which the storage container 41 exposes the view of the slotted guide 34 .
  • the slotted guide 34 provides a straight guide track in its lower portion for the guide means 43 , allowing only linear upward movement of the storage container 41 vertically parallel to the plane of the front panel 31 . As shown in particular in FIG.
  • the guidance of the storage container 41 in the slotted guide 34 exists only for a lower section of the storage container 41 . From a certain height position of the storage container 41 , the guide means 43 leave the slotted guide 34 . In order to guide the guide means 43 safely back into the slotted guide 34 when the movement is reversed, the guide track of the slotted guide 34 widens upward in a funnel shape to an insertion opening 35 .
  • a pivoting movement of the pivot arms 44 leads to a movement of the storage container 41 and—due to the coupling of slotted guide 34 and guide means 43 —to a sliding movement of the pull-out guide 32 and the front panel 31 .
  • a further guide can consist in the fact that the storage container 41 rests with its underside on the lower floor 22 of the body 2 and is thus also guided horizontally. The conversion of the pivoting movement of the pivot arm 44 into the linear sliding movement of the storage container 41 is thereby made possible by the corresponding stroke degree of freedom of the sliding and pivot bearing 42 .
  • a pure pivoting movement of the storage container 41 can also be implemented if the floor 22 has a correspondingly curved shape or there is sufficient clearance to the floor 22 so that the floor 22 does not determine the movement of the storage container 41 .
  • the sliding and pivot bearing 42 is positioned at a stop with respect to the sliding movement, so that the storage container 41 only follows the pivoting movement of the pivot arm 44 as of this position.
  • its orientation i.e., its angular position with respect to a rotation about a horizontal axis, is determined by the vertical guidance of the guide means 43 in the slotted guide 34 .
  • a front panel 31 is provided that exposes an opening in the body 2 through which the storage container 41 is moved out.
  • the front panel 31 is not guided linearly by a pull-out guide (cf. pull-out guide 32 in the first exemplary embodiment), but is designed as a flap which can be swung open downwards and is pivotably secured to the body 2 by a hinge or pivot arrangement not shown here.
  • a slotted guide 34 is formed on the front panel 31 or a common support on each of the sides of the storage container 41 , in which the storage container 41 is guided by guide means 43 in sections of the movement sequence.
  • guidance of the storage container 41 can also take place during a pivoting movement of the front panel 31 in such a way that it is moved out of the body 2 by a pivoting movement of the pivot arms 44 , thereby opening the front panel 31 .
  • the storage container 41 leaves the guide along the front panel 31 and is guided in a pivoting movement to a convenient removal position substantially corresponding to that shown in FIG. 3 e or f of the first exemplary embodiment.
  • the storage container 41 When the pivot arms 44 are pivoted back in, the storage container 41 is first lowered while maintaining its relative pivot position with respect to the pivot arms 44 , with the guide means 43 entering the insertion opening 35 of the slotted guide 34 . Further pivoting moves the storage container 41 into the body 2 and closes the front panel 31 .
  • a curved design of the guide track can be provided in this exemplary embodiment, as in the first exemplary embodiment, in order to achieve a particularly smooth and harmonious movement sequence of both the storage container 41 and the front panel 31 .
  • FIG. 6 shows, in the form of an isometric representation analogous to FIG. 1 f , a further exemplary embodiment of a household appliance 1 .
  • This essentially represents a further development of the first exemplary embodiment, in which the front panel 31 performs a linear pull-out movement as part of a sliding arrangement.
  • a protective covering 47 is provided around at least three sides of the storage container 41 , specifically the front surface facing the user and the two sides, which is telescopically configured and is raised and extended with the storage container 41 .
  • the protective covering 47 prevents objects or body parts from entering a gap between the storage container 41 or other components of the pivot arrangement 4 and the front panel 31 or the frame elements 33 or other components of the front panel arrangement 3 . In this way, a risk of entrapment between moving components is reduced.
  • the protective covering 47 can be lifted along in the form of an apron and can be provided in addition to a linear guide that is present between the front panel arrangement 3 and the storage container 41 .
  • the linear guide can extend over only part of the vertical movement of the storage container 41 , as shown in the first example, or it can be formed over the entire vertical range of movement of the storage container 41 relative to the front panel arrangement 3 .
  • the protective covering 47 can be connected to the storage container 41 or front panel arrangement 3 by means of bolts or elastic elements, such as ropes.
  • the protective covering 47 may have spring elements that push it upwards as soon as the storage container 41 is raised. When the storage container 41 is lowered, it presses down the protective covering 47 against the spring force.
  • the protective device 47 may itself be configured as a linear guide that guides vertical movement of the storage container 41 relative to the front panel arrangement 3 .
  • FIGS. 7 a and 7 b each show a sectional view of a further household appliance 1 .
  • the exemplary embodiment shown here corresponds to those described previously, to the description of which explicit reference is hereby made.
  • a storage container 41 is guided so that it can be extended from a body 2 and lifted, with a front panel arrangement 3 being extended as well.
  • the pull-out guide 32 is formed as a full extension pull-out guide comprising a body rail 321 mounted on the body 2 , a center rail 322 slidably mounted with respect thereto, and a running rail 323 slidably mounted with respect thereto.
  • a locking lever 324 is pivotally mounted on the track.
  • the locking lever 324 is formed as a two-sided lever, with a front lever arm of the locking lever 324 projecting freely forward toward the front panel 31 .
  • the opposite rear lever arm is provided at its end with a downwardly projecting pawl 325 .
  • FIG. 7 a shows an extended and lowered position of the storage container 41 .
  • a protruding actuator 411 arranged on the side of the storage container 41 pushes down the front lever arm of the locking lever 324 .
  • the actuator 411 is bolt-shaped in the example shown.
  • the locking lever is formed at a slight angle, which raises the rear lever arm with the pawl 325 . In this position, the pawl 325 does not interfere with the pull-out guide 32 , allowing it to retract unimpeded.
  • FIG. 7 b shows an extended and (slightly) raised position of the storage container 41 .
  • the actuator 411 is raised and no longer acts on the front lever arm of the locking lever 324 . Due to gravity, this causes the rear lever arm of the locking lever 324 to lower with the pawl 325 .
  • the pawl In the fully extended position of the pull-out guide 32 shown, the pawl extends past the center rail 322 to in front of the front end of the body rail 321 , blocking reinsertion of the pull-out guide 32 .
  • the pawl 325 Only when the storage container 41 has been substantially completely lowered, as shown in FIG. 7 a , is the pawl 325 raised again and the movement of the running rail or center rail relative to the body rail 321 is enabled again.
  • the locking lever 324 can be pretensioned in the locking direction with a force accumulator, e.g. a spring.
