Definitions

  • the invention relates to a housing part of a household appliance according to the Preamble of claim 1 and a housing for a household appliance with such a housing part and a household appliance with a such housing.
  • housing parts of household appliances such.
  • the door of a dishwasher are from a variety of different parts from partially very different Materials meticulously assembled. So they have one outer shell of sheet metal and an inner shell of stainless steel or thermoplastic (i.e., molded) plastic (eg, polypropylene), a flow-insulating mat for thermal insulation, a bitumen mat for Sound and vibration damping and a metal construction for attachment from hinges up. All of these parts must be predominantly through Screwing to the finished dishwasher door will be assembled. This complex installation is time consuming and costly. In addition, for the many different parts requires a costly storage.
  • thermosetting plastic such as foamed thermosetting plastic
  • B. polyurethane foam is achieved that for the housing part of the household appliance significantly fewer different parts are needed because due the high thermal, sound and vibration insulation values of the thermoset Plastic no insulation and other mats and because The high stability of the thermosetting plastic also no stiffeners more must be installed.
  • the housing part is a Door or a lid of the household appliance.
  • a lock, hinges, connecting, fastening or stiffening elements can at least partially foamed into the plastic be. Furthermore, screw threads, cable ducts, trachea, condensed water pipes or moldings for fixing other components be formed of the housing part in the plastic part.
  • operating, display and / or Controls of the household appliance applied to the plastic part or completely or partially foamed in the plastic. at the operating element may be a membrane keyboard in the display element to displays or individual LEDs and / or in the Control to act preferably encapsulated control electronics.
  • the entire housing part is preferably made of the thermoset Assembled plastic part and one or more other components.
  • a Plastic shell preferably made of a thermoplastic material consists of, or a metal shell, which is preferably made of stainless steel, be.
  • a conventional dishwasher door has an outer sheet metal shell 1 and an inner plastic or stainless steel shell 2. In between lie a flow-insulating mat 3 and bitumen mats 4.1 to 4.5.
  • a detergent container 5 In an opening 2.1 of the inner shell 2 is a detergent container 5 by means of a from the other side of the inner shell 2 screwed holding frame 6 attached.
  • a metal frame 7 is used to stiffen the outer Sheet metal shell 1 and for attaching hinges 7.1 and 7.2 to the screwed outer shell 1.
  • On the outer shell 1 sits a control and display part 8 on which a membrane keyboard 9 is mounted.
  • An electronic control unit 10 is in a plastic housing 11 with a lid Housed 12 and attached to the outer shell 1.
  • a lock 13 and a fan component 14 with integrated fan and air duct. The fan output is provided with a Filterabdeckkappe 15.
  • For stiffening the door construction is still a metal rod 16 screwed to the inner shell 2.
  • FIG. 2 The outer sheet metal shell is through a Plastic part 1 'replaced by foamed thermosetting plastic.
  • the control and display part 8 ' is integrated in this plastic part 1', d. H. made in one piece with this.
  • the hinges 7.1 and 7.2 are partial in the plastic of the plastic part 1 'with foamed and thus already firmly connected with this.
  • the (welded or not welded) control electronics 10 can - without them only in one own housing would have to be accommodated - in the plastic part 1 'inserted, glued or even foamed.
  • the plastic part 1 is produced by means of polyurethane integral foam technology.
  • PU foam as a thermosetting plastic, has a number of advantages: In the production, no high pressure such. B. during the casting of thermoplastic required. Thus, the tools needed easier to manufacture and cheaper, resulting in smaller series and thus different Gepatiusefronten or shapes for different Device types are possible.
  • PU foam is flame-retardant (it only burns above 500 ° C) and has high insulation and damping values concerning heat, sound and vibrations.
  • By the relative high wall thickness of plastic parts made of PU foam have this a high stability and do not need additional through - however quite possible - insertion or lathering of stabilizing elements be stiffened.
  • a coloring of the plastic part 1 ' is also as a variation of the degree of hardness of the material or the surface possible.
  • plastic when using plastic is a higher given creative freedom, so that contours, air and condensed water tubes as well as cable channels as desired depending on the requirements can be.
  • operating, display and control elements by attaching to or by at least partial foaming be integrated into the plastic part 1 '.
  • the invention is not limited to the embodiment described. So she can z. B. also with doors or covers of cooling and Freezers or chests find use. In addition, you can also all other housing parts of household appliances in the context of this invention be educated.
