Definitions

  • the invention relates to a securing element made of bent wire for a tubular heater of a washing machine, also to a system for fastening a tubular heater using a securing element made of wire and also to a washing machine having a system for fastening a tubular heater using a securing element made of wire.
  • Known commercial elements made of wire for securing tubular heaters for washing machines comprise one piece wires which are inserted into a mount made for this purpose inside the washing machine tub.
  • the tubular heater which the known prior art securing element is designed to secure is of the same type as that which the securing element of the invention is designed to secure. It is a type of tubular heater which comprises one tube part and one sealing mount part.
  • the tubular heater is introduced through an opening in a wall of the tub such that the tube part is located inside the tub and the sealing mount is firmly fixed to the wall of the tub, closing and sealing it.
  • the heating tube or tubes extend from said sealing mount.
  • a first portion of the tubes or tube extends towards the interior of the tub parallel to a second wall of the tub which is perpendicular to that to which the sealing mount is fixed and the tube turns back on itself to form a second portion parallel or virtually parallel to the first.
  • This second portion may join up with the sealing mount again or, in a third portion, it may turn back on itself to extend towards the interior of the tub parallel to the first and second portions and then turn back on itself again to form a fourth portion parallel to the previous three and fastened to the sealing mount at the wall of the tub.
  • the tube is configured as a zigzag tube with parallel or virtually parallel tube portions arranged in a plane parallel to the wall of the tub which is perpendicular to the wall to which it is fixed via the sealing mount. Conventionally, these tube portions form a slight angle between them opening out towards the interior of the tub.
  • the tube is of circular section but over virtually its entire length it has a rib protruding outwards. The rib results from the method of manufacturing this type of heating tube.
  • the prior art securing element has a mounting portion which is a part of the bent wire which is inserted into a slot in the tub. From the two ends of the wire mounting portion, two arms extend in parallel towards the interior of the tub. These two arms rise in parallel and bend in concave manner towards one another and then away from one another again. They are bent such that each of them clasps a portion of the heating tube over part of its perimeter. In this way, the tubular part of the heater is fastened inside the tub at a distance from the wall of said tub.
  • this fastening element may come into contact with the heater in a zone comprising a cross-sectional rib and that over time it may succeed in damaging it due to vibration. Also, it may happen that, during assembly, on insertion of the heater, the tubes bend one or both of the arms of the wire resulting in the heater not being properly fastened in place.
  • a securing element made of bent wire for a washing machine tubular heater which comprises a first mounting portion for connecting the securing element for the tubular heater to a mounting base of a washing machine, and a clip portion extending upwards from the mounting base with at least two opposing wire arms, in which each one of the arms has a first contacting portion, a first noncontacting portion following the first contacting portion, a second contacting portion following the first non-contacting portion and being arranged in a higher position than the first contacting portion, a second non-contacting portion following the second contacting portion, in which the second non-contacting portion is arranged at the highest position of the securing element for the tubular heater, and in which the opposing wire arms additionally have a third contacting portion following the second non-contacting portion, a third non-contacting portion following the third contacting portion, and in which at least one of the two opposing wire arms has a fourth contacting portion following the third non-contacting portion and arranged in a lower position than the third
  • each arm of the securing element for the tubular heater secures the latter in at least three zones and at least one of the arms secures it in four zones, which much more reliably reduces heater vibrations and therefore reduces friction between the heater and the wire of the securing element.
  • the two opposing wire arms have a fourth contacting portion following the third non-contacting portion and which is arranged in a lower position than the third contacting portion.
  • the mount additionally comprises a second mounting portion on at least one of the opposing wire arms following the fourth contacting portion for connecting the securing element for the tubular heater to the mounting base of the washing machine. In this way, the joint between the securing element and the mounting base is much more stable and it is not readily bent through lateral pressure on the arms.
  • the opposing wire arms cross over each other at the first non-contacting portion and the third non-contacting portion to form an X, which gives the securing element greater flexibility.
  • This embodiment may be such that one of the opposing wire arms passes between the first non-contacting portion and the third non-contacting portion of the other wire arm, so facilitating the process of manufacture in the wire bending machine.
  • first non-contacting portion and the third non-contacting portion of each arm are bent away from the opposing arm so as not to cross but to form two mutually facing Cs with concavities for receiving the tube portions of the tubular heater.
  • the securing element for the tubular heater is made of a continuous piece of wire of a diameter of between 0.5 and 4 millimeters, preferably between 1 and 3 millimeters, particularly advantageously 1.5 and 2.5 millimeters, in particular 2 millimeters.
  • the opposing wire arms are flexible such that they exert force on the tube portions of the tubular heater so as to separate them. It is also particularly advantageous for the wire to be of stainless steel, which ensures durability in a damp environment.
  • the object is achieved according to claim 13 by means of a system for fastening a washing machine tubular heater using a tubular heater securing element as described above, in which the heater is inserted by sliding in an insertion direction substantially perpendicular to the plane of elevation of the securing element fastening a first end of the tubular heater to the securing element.
  • the plane of elevation should be understood to mean that formed by the arms of the clip portion rising in parallel or by the plane formed by the parallelism of the contacting portions of the arms in order that the tubes of the heater may enter without difficulty.
  • the second end of the tubular heater has two tube portions, which are secured by the clip portion, forming an angle with the insertion direction of from 0° to 10°, preferably between 0° and 5°, particularly advantageously 0° and 3°, in particular 2°, which facilitates insertion into the clip portion of the securing element since said portion opens up on passage of the tubes and increases the pressure exerted thereon and then the opposing wire arms flex relative to their empty position on insertion of the heater so as to secure the tubular portions.
  • a second end of the tubular heater is fastened to a wall of the mounting base, so meaning that the heater is fastened by the tubes and by the second end, giving a better response to vibration.
  • the object is achieved according to claim 17 by means of a washing machine with an above-described fastening system for a tubular heater, which washing machine has a washing tub formed of a first half-tub and a second half-tub and in which the mounting base is arranged in the first half-tub.
  • the wall of the mounting base is a wall of the first half-tub which has an orifice for insertion of the tubular heater and in which the latter is fastened by its second end, closing said orifice hermetically, only the heater's electrical connections remaining outside the tub away from the risk of dampness.
