Definitions

  • the present invention relates to cooking appliances and, more specifically, to cooking appliances having a housing which defines a food preparation cavity, heating means for heating the cavity, and a door for selectively closing and opening the cavity.
  • Cooking appliances having a heatable cavity such as electric heating ovens, steam ovens, convection ovens, gas ovens, microwave ovens, combination ovens or heating cabinets typically have a door that is pivotable about a horizontal axis.
  • the above object is solved in that the cooking appliance further comprises a horizontally movable linkage system connected to the housing and the door, wherein the linkage system is configured to move the door between a closed position in which the door bears against the front side of the housing to close the oven cavity, via an intermediate position in which the door is lifted off from the front side of the housing, and an open position in which the door is positioned laterally aside the oven cavity, wherein during the entire path of movement the door is held in a vertical orientation.
  • a linkage system by means of which the door can be displaced to an open position in which the door is located aside the cavity where it does not interfere with the user of the cooking appliance, who when placing food items into the cavity or when removing food items from the cavity is standing in front of the cooking appliance. Furthermore, since the door when moving between the closed position and the open position does not perform a rotating movement but instead is kept during the entire path of movement in a vertical orientation, wherein for an opening movement the door first is lifted off from the front side of the housing and then is shifted sideways towards the open position, only little space is required for the movement of the door. In the open position the door does not overlap the oven cavity but is positioned laterally aside the oven cavity, so as to allow for an obstructed access to the entire oven cavity.
  • the door in the open position can be positioned in a plane that is located offset to, and in front of, the plane in which the door is positioned when in the closed position.
  • the plane in which the door is positioned when in the open position can extend substantially parallel to the plane in which the door is positioned when in the closed position.
  • cooking appliances as described herein often are installed aside further devices or items of kitchen furniture, such as a cabinet for installing another kitchen devices, such as a refrigerator, a cupboard or the like, in the open position in which the door is located sideways from the oven cavity where it may be placed in front of a neighboring kitchen element, the door is held at a distance from such neighboring elements.
  • a heating operation in which case the inner side of the door may have been heated to a considerable temperature, heat radiating from the door thus can be dissipated in the free space thus maintained between the opened door and a neighboring device or piece of furniture.
  • the installed devices and pieces of furniture are mounted such that the fronts thereof are located in a common plane. While thus the front of a neighboring kitchen element typically will be located in the same plane as the door of the oven when in the closed position, the offset between the plane in which the oven door is positioned when in the open position and the plane in which the oven door is positioned when in the closed position advantageously has a value of between 40 mm and 80 mm plus the thickness of the door.
  • the distance between the inner side of the door when the door is positioned in the open position, and the plane in which the exterior side of the door is positioned when the door is in the closed position is at least 40 mm, and preferably is at least 50 mm.
  • the horizontally movable linkage system comprises a first linkage assembly that is located above the cavity, and a second linkage assembly that is located below the cavity, which allows for a stable and reliable guiding of the door along its path of movement. While also different linkage assemblies could be used as the first and second linkage assemblies, the manufacturing can be facilitated when the second linkage assembly corresponds to the first linkage assembly.
  • the linkage system may comprise at least one double lever system comprising a first and a second lever pivotally linked to the housing and the door, wherein at least one of the first and the second lever can be configured as a curved lever.
  • Providing for at least one curved lever provides more freedom in the selection of the pivot points, because by providing for a curved portion interference of the levers can be avoided also when the levers are hinged to pivot points that are located close to each other.
  • a curved portion particularly towards the end of the lever that is attached to the door facilitates implementing a configuration in which the door does not overlap the oven cavity, because by means of the curved portion which advantageously is provided at a position which in the open position of the door is in the vicinity of the front edge of the housing, the door can be positioned at a position that is located further sideways as if straight levers were employed.
  • the linkage system may comprise at least one lever assembly having a lever, one end of which is pivotally linked to a fixed pivot point at one of the housing and the door, and the other end of which is pivotally linked to a carriage which is guided in a rail provided at the other of the housing and the door.
  • the linkage system comprises at least one lever assembly having a pair of levers, preferably curved levers, each lever having a first end which is pivotally linked to a fixed pivot point at the door, and a second end which is pivotally linked to a fixed pivot point at the housing.
  • the at least one lever assembly can have a first and a second lever the first ends of which are pivotally linked to fixed pivot points at the door, and the second ends of which are pivotally linked to fixed pivot points at the housing, wherein the pivot points at the door are located aside each other, and wherein the pivot points at the housing are located behind each other, i.e. aligned to a side wall of the housing, or laterally offset behind each other.
  • the two levers can be positioned substantially in the same horizontal plane which requires the least vertical space for accommodation of the lever assemblies.
  • the cooking appliance further can comprise a motor for displacing the lever assembly, so as to conveniently open and close the door by manually activating a button, for example a sensor provided at the door face, or for automatically activating the door by the program control of the cooking appliance.
  • a motor for displacing the lever assembly, so as to conveniently open and close the door by manually activating a button, for example a sensor provided at the door face, or for automatically activating the door by the program control of the cooking appliance.
  • the motor can be coupled to the lever assembly via a drive element, such as a cable, in particular a Bowden cable, a chain or a pulling wire.
  • the cooking appliance further can comprise sealing means between the door and the housing, the sealing means extending about the circumference of the cavity so as to seal the cavity when the door is in the closed position.
  • the first linkage assembly is located above the sealing means and the second linkage assembly is located below the sealing means, so that the linkage assemblies do not interfere with the sealing means.
  • the cooking appliance further comprises a coupling for releasably attaching the door to the movable linkage system.
  • the coupling can comprise a first coupling element which comprises the pivot points at which the first ends of the levers are pivotally linked, wherein the door comprises a second coupling element, for example a snap-in connection, which can be releasably coupled with the first coupling element to mount the door at the linkage system.
  • the door can be easily removed, for example for cleaning purposes, and also can be easily reinstalled, preferably without any tools being required.
  • Fig. 1 shows the upper part of an oven 10 when viewed from above.
  • the oven comprises a housing 11 in which there is provided an oven cavity 12 which can be heated in any conventional manner, such as by radiative heating elements, by hot air or steam that is introduced into the oven cavity, by gas, by microwave heating, or any combination thereof.
  • a door 14 At the front side of the oven there is provided a door 14 which abuts against the front side 15 of the housing so as to close cavity 12.
  • a sealing 16 is arranged between the door and the front side 15 of the housing. While in the embodiment shown in the figures, see particularly Figs. 2 and 3 , the sealing 16 is attached to the front side 15 of the housing 11, in the alternative the sealing 16 could be fixed at the door 14.
  • the door 14 comprises a frame 18 at which there is connected a glass pane 20 which in the closed position of the door allows a free view into the cavity 12 through the central region of the door.
  • a handle 22 At the front side of the door 14 there is installed a handle 22 to manually operate the door.
  • Linkage assembly 24 comprises a first lever 26 and a second lever 28. At a first end, levers 26 and 28 are attached at pivot points 30 and 32 to the door 14. As shown in Fig. 1 , pivot point 30 of lever 26 is provided at the frame 18 at a position close to one of the lateral edges of the door 14, which in the embodiment shown in the drawings is the right edge. Pivot point 32 of lever 28 is provided at the frame 18 to the left of pivot point 30.
  • levers 26 and 28 are attached at pivot points 34 and 36 that are fixed with respect to the housing 11 and which are positioned in a rear portion of the housing in the vicinity of the left wall of housing 11.
  • the door 14 when rotating the levers 26 and 28 the door 14, starting from the closed position shown in Fig. 1 in which the door 14 bears against the front side 15 of the housing 11 in which it closes the oven cavity 12, the door is lifted off from the front side 15 of the housing 11 and is moved laterally (in the figures to the left) via an intermediate position shown in Fig. 2 into an open position shown in Fig. 3 in which the door 14 is positioned laterally aside the oven cavity 12. While as illustrated in Fig.
  • the door 14 during its travel between the closed and open positions may attain an orientation in which the door is positioned at an angle to the front side of the oven, in the closed position the door advantageously is positioned in parallel to the front side of the oven, so as not to interfere with a user who is standing or moving in front of the oven. Irrespective of whether the door during its travel between the closed and open positions is held substantially parallel to the front side of the oven, or attains an orientation in which it is positioned at an angle to the front side of the oven, during the entire path of movement the door is held in a vertical orientation.
  • a motor 38 for actuating the linkage assembly 24. While motor 38 could be directly coupled to linkage assembly 24, in the embodiment shown in the drawings, motor 38 is connected to the linkage assembly 24 via a drive element 40 which is implemented as a cable that connects to an eye 42 provided in an extension of the second lever 28 which is located opposite lever 28 beyond pivot point 36, wherein the extension in which eye 42 is provided thus forms a short lever arm of lever 28.
  • drive element 40 which is implemented as a cable that connects to an eye 42 provided in an extension of the second lever 28 which is located opposite lever 28 beyond pivot point 36, wherein the extension in which eye 42 is provided thus forms a short lever arm of lever 28.
  • lever 26 which similarly as lever 28 has an extension that forms a short lever arm beyond the pivot point 34 which comprises an eye 44.
  • a compression spring 46 acts on eye 44 of lever 26 to bias the door 14 towards the closed position.
  • the configuration of the spring 46, motor 38 and drive element 40 could be designed so that the spring 46 is a tensioning spring which biases the door 14 towards the open position, wherein either the drive element 40 provides for a pushing force, such as by the use of a Bowden cable, or the motor 38 is arranged towards the front side of the oven 10 so as to provide for a pulling force onto drive element 40 towards the front side of oven 10.
  • Figures 4 and 5 illustrate an embodiment in which the pivot points for levers 26 and 28 are provided on a first coupling element 48 which cooperates with a second coupling element 50 that is provided at the door.
  • first coupling element 48 can be configured as a plug-in connector configured for insertion into a second coupling element 50 that forms a receptacle for the plug-in connector 48, wherein the plug-in connector 48 can be arrested within receptacle 50 by means of a catch 52 which in the assembled position of the door 14 is released into a recess 54 provided in the second coupling element 50.
