Definitions

  • the invention relates to a structure of an electrical household element such as a washing machine and its manufacturing process. It relates more particularly to washing machines of the rotary drum type for household use.
  • washing machines are generally made up of a metal frame on which are fixed the various elements making up the machine such as the water recovery tank, the drive, heating, draining devices, etc. , said frame being wrapped with a painted or enameled sheet metal lining which ensures good aesthetics for the whole.
  • the water recovery tank the framework itself generally composed of sub-elements
  • the external sheet metal constitute separate elements which therefore require assembly and, by their sheet metal design, they need to be preformed, treated and painted, possibly welded, which results in costly manufacturing.
  • the object of the present invention is to present a structure for a washing machine which makes it possible to save many parts currently used since it combines several functions.
  • the structure of the washing machine of the present invention makes it possible to support the various components of the washing machine and therefore replaces the traditional framework. Then, it replaces the external sheet metal by presenting external dimensions identical to the standardized values currently adopted in this field.
  • the structure of the present invention has a water recovery tank of dimensions substantially identical to those generally adopted.
  • the washing machine structure of the present invention has its own mass which enables it to avoid the use of a ballast associated with the rotary drum.
  • Another object of the present invention is to present a process for manufacturing the structure which has the properties. rees previously, at very low cost since it is a manufacturing by automatic molding which is therefore likely to be mass produced at high speed.
  • the structure of a drum washing machine intended in particular for the domestic cleaning of linen which comprises in particular a drum rotating in a water recovery tank, a device for driving, filling with water and cleaning and other products, for emptying, the assembly being controlled by a control mechanism, is characterized by the fact that it is made of molded concrete and serves to support the various elements making up the washing machine and furthermore forms in its internal part the water recovery tank .
  • FIGS 5a, b and c schematically represent different stages of the method of manufacturing a washing machine structure according to the invention.
  • Traditional washing machines of the drum type intended in particular for household cleaning of linen are essentially consisting of a rotary drum and its drive device associated with a water recovery tank, the latter being resiliently mounted on a frame.
  • a water recovery tank Around said tank are grafted various auxiliary elements such as, as shown in FIG. 1, devices 1 for filling the tank 2 with water and cleaning products and the like, of a heating system 3, of emptying 4, the assembly being controlled by a control mechanism 5.
  • the frameworks of current washing machines are wrapped by a sheet metal trim.
  • the structure 6 of the washing machine serves to support the various elements making up the machine such as in particular those listed above. Consequently, it is a self-supporting structure which does not require the use of an auxiliary chassis.
  • the structure 6 has an internal shape in the form of a bowl 2 for recovering water, inside which is arranged the traditional rotary drum 7.
  • the exterior surfaces of the structure 6 of the invention will have a traditional parallelepiped appearance.
  • the structure of the invention combines several functions, the self-supporting chassis, the water recovery tank, the external covering and the traditional ballast can be omitted due to the nature of the material used for the manufacture of the structure with relatively dense density since it is a preferred form of molded concrete.
  • the structure of the present invention will advantageously consist of two assembled parts. Indeed, both in terms of manufacturing and assembly, it is preferable to use two preferably symmetrical parts.
  • FIGS. 2a and b give an example of the design of a structure which will be produced by assembling two parts 8 shown which are particularly simple to produce.
  • the parts 8 have the form of three flat panels 9, 10 and 11 assembled in the shape of a U inside of which is disposed a transverse partition 12 acting as a tank bottom.
  • part 8 made in Figures 2a and is simple disregard of certain details such as the reservations necessary for the installation of the various components of the washing machine which have not been shown.
  • the drive of the drum 7 will have to be designed in a somewhat particular way with respect to that currently used.
  • FIG. 3 shows a structure of a washing machine according to the present invention which, however, is more particularly suited to the use of a device for driving the drum 7 of the traditional type.
  • the parts 8 have, in addition to the reservation necessary for the formation of the tank, an adjacent reservation 13 inside which the transmission 14 of the drum 7 can be accommodated.
  • the transmission device 14 envisaged in FIG. 3 is of the traditional type, that is to say of the pulley-belt type. In this way, the drive motor can be housed in the lower part of the structure and drive the drum 7 located in the tank.
  • FIGS. 4a and 4b respectively in top view and in front sectional view represent the parts 8 of structure having a longitudinal groove 15 which allows them to receive a plate 16 partitioning of the water recovery tank 2.
  • the drum 7 can be driven by a motor 17 arranged in the lower part of the structure 6 by means of a set of pulleys and belt 14.
  • the plate 16 may have a folded lower part 18 on which we can have different parts of the machine.
  • the plate used can be made! in a plastic material such as PVC or in a fiber cement board.
  • the concrete used to make the structure can be loaded with glass beads or other density-reducing additive, so that the finished product is of reasonable weight.
  • the exterior surfaces of the structure may be covered with an epoxy resin coating which will in particular give them good aesthetics.
  • the coating used may reinforce the iso thermal lation of concrete.
  • the thermal insulation of the water recovery tank can be reinforced by applying a thermal insulation coating inside it.
  • the assembly of the two parts 8 constituting the structure 6 it will be very advantageous to design the latter in an elastic manner. Indeed, it is known that the unbalance does not fail to be caused in the drum by the asymmetry of the linen which is located there, and causes significant vibrations. Also, the assembly of the two parts 8 of the structure by means of an elastic connection makes it possible to minimize, very significantly, the amplitude of the vibrations.
  • Each of the parts plays a role of shock absorbers vis-à-vis the other.
  • damping elements such as foams on the lower surface of the structure.
  • the sharp edges forming the points of weakness of the concrete we can, for example, surround the lower part of the structure using for example, a metal angle in order to reinforce it.
  • the assembly of the two parts 8 forming the structure can advantageously be carried out using a sealant sealant.
  • FIGS 5a, b and c show schematically the different phases of the manufacturing process of a washing machine structure as described above. It is a production by molded concrete which can advantageously be carried out automatically.
  • FIG. 5a shows diagrammatically the filling phase of the mold 19 in which concrete 20 is distributed above the mold, the latter possibly being vibrated to facilitate its filling, by translation of a hopper 21.
  • the quantity of concrete distributed by the hopper corresponds to the capacity of the mold.
  • the part is compressed in a jack 22.
