Definitions

  • the present invention relates to household appliances, and in particular to household appliances provided with doors in order to allow the user accessing to inner compartments of the household appliances.
  • a (typically front) panel of such type of household appliance defines a door that can be opened for accessing the inner cooking compartment.
  • the panel defining the door can be formed by a glass plate, having variable sizes, possibly surrounded by a more or less extended frame, of the same material (typically metal) as the oven case.
  • a door handle is applied in order to facilitate the door opening operation.
  • the door handle is usually of the same material as the oven outer case and/or of the peripheral zone around the glass plate, but however not of glass.
  • the door handle made of metal, is fixed to the upper portion of the glass plate of the door through the use of suitable screws.
  • EP0723116 there is proposed to fix a metal door handle in an appropriate position of the glass plate of the door through a gluing operation.
  • the gluing of the metal door handle directly on the glass plate has criticalities because of the difference between the two materials (metal-glass) in the molecular point of view.
  • the gluing of a material characterized by an ordered molecular structure, such as metal with a material characterized by an amorphous, and thus disordered, structure, such as glass, can not ensure a reliable and durable coupling especially in case of intensive use of the household appliance.
  • a household appliance having a door associated to an access opening to an inner compartment of the household appliance itself, wherein the door includes a glass plate and a door handle, and the door handle is of the same material as the glass plate and is glued to the glass plate.
  • the door can be provided with a door handle having substantially a parallelepiped shape.
  • the door handle may include a further downward curved portion of the door handle, such portion extending from the free end of the door handle, in order to facilitate the grip by the user.
  • the door handle may include a cavity in a face thereof having a greater length, within which the user may insert its hand fingers.
  • the household appliance may in particular be an oven.
  • a further aspect of the following invention relates to a method for making a household appliance door; the method includes the steps of providing a glass plate, providing a door handle of the same material as the glass plate, and finally performing the gluing the door handle on the glass plate.
  • the door offers to the user a wide view towards the interior of the household appliance (since all the surface thereof may be formed by a glass plate), a high gluing yield of the door handle and a general reduction of the production costs of the household appliance, since the criticalities connected with the execution of holes in the glass plate for screwing the door handle are avoided.
  • an oven 10 in an embodiment known in the state of the art; the oven 10, of generally parallelepiped shape, includes two opposite side walls 11, a base 12 to which floor resting feet 13 are mounted, and an top wall 19; typically, the side walls, the wall defining the base and the top wall are made of metal.
  • the oven is also provided with a front wall 15, made of metal too, with a central opening for accessing an inner compartment of the oven, adapted to house food to be cooked.
  • a door 14 is associated with the central opening in the front wall 15, the door that can be opened for accessing the inner compartment of the oven.
  • the door 14 includes a central glass plate 16 surrounded by a peripheral metal frame 18.
  • Another known solution provides the screwing of the metal door handle 17 directly on the glass plate 16, and in this case the peripheral frame 18 may not be provided; however, in this case the problems discussed in the introduction of possible breakage of the glass plate are encountered.
  • Figure 2 schematically shows, in a similar view to that of Figure 1 , an oven 20 provided with a door according to an embodiment of the present invention.
  • the oven 20, as well as the oven 10 of Figure 1 generally is parallelepipedshaped, and includes two opposite side walls 21, a bottom base 22 to which floor resting feet 23 are mounted and an top wall; typically, the side walls, the wall defining the base and the top wall are made of metal.
  • the oven is also provided with a front wall 25, made of metal too, with a central opening for accessing an inner compartment of the oven, adapted to house food to be cooked.
  • the door 24 includes a glass plate 26, possibly surrounded by a peripheral frame 28, for example made of metal.
  • a glass door handle 27 is fixed in an approximately central area of the glass plate 26 through a gluing operation; such operation allows obtaining a high reliability of the door handle-door system (since the gluing occurs between two materials having the same molecular structure), and facilitates and makes the mounting operation of the door handle less critical, being not necessary to perforate the glass plate for making the holes for the screws, which translates in a production costs reduction.
  • the gluing can be achieved by using any glue on the market particularly suitable to the stable gluing of two glass pieces to each other, such as a UV-hardening adhesive glue.
  • the solution according to an embodiment of the invention allows obtaining a wide view towards the interior of the oven (thanks to the fact that the peripheral frame of the door, if provided, can have a very reduced height).
  • the door handle-door system made entirely of glass as above described may appear aesthetically more pleasant and refined.
  • the described door handles can be arranged in directions different from that described according to an embodiment; in particular the door handle may conveniently be arranged perpendicularly to the edge 26A of glass plate (so as to allow, such as in the case of microwave ovens, a side opening of the door), or obliquely, both for functional reasons and for aesthetic reasons.
  • the peripheral frame of the glass plate 26 may not be provided, or even be of glass, so as to create a sort of chromatic continuity between the glass plate and the peripheral frame.
  • the front wall 25 of the oven may not be provided and be entirely replaced by the glass plate of the door (with or without the peripheral frame).
  • the shape and size of the door handle may be different from those previously described and illustrated in the attached figures.
  • the door handle may be rounded C-shaped, or may be T-shaped or L-shaped with a single gluing area to the glass plate.
  • the gluing area, or the gluing areas of the door handle to the glass plate must still be sufficiently extended to allow a gluing strength sufficient to avoid detachment in all operating conditions of the household appliance.
  • the door handle could also be provided with gripping elements facilitating the grasp, for example coatings of elastomeric material in the grasping area.
  • the present invention has been described and illustrated with reference to an oven, it is clear that it can be adopted in any type of household appliance (e.g., a dishwasher or a refrigerator) provided with a door that can be opened for accessing an inner compartment of the door appliance, wherein such door has a glass portion (typically a plate) on which a door handle is glued.
  • a glass portion typically a plate
