  • circuit boards which are placed into the appliance body and which control at least the operation of the device by means of to the electrical circuits provided thereon are used.
  • Said circuit boards are mounted to the mounting regions in the body of the electrical household appliances which are not susceptible to impacts from outside in order to prevent the sensitive electronic circuits thereon from getting damaged.
  • the circuit board is mounted onto a mounting surface in a suitable region in the body of the electrical household appliance preferably by means of fixing means.
  • Figure 1 shows the circuit board (5) mounting region of an electrical household appliance (1) having a circuit board (5) mounted by means of a state of the art fixing apparatus (FA) while Figure 2 shows the fixing apparatus (FA) which is used for the mounting of the circuit board (5) in the state of the art.
  • An assembly structure (AS) is realized on the mounting surface (S1) which is defined in the body of the electrical household appliance and at least one mounting hole (H1) is provided on said assembly structure (AS).

  • the fixing apparatus (FA) is placed onto the mounting surface (S1) such that the first hole (H2) is aligned with the first mounting hole (H1) on the assembly structure (AS) and the fixing apparatus (FA) is fixed onto the assembly structure (AS) and thus onto the mounting surface (S1) by means of a connection means (CM) such as a screw which is passed through the first hole (H2) and the first mounting hole (H1).
  • CM connection means
  • the circuit board (5) is positioned on the fixing apparatus (FA) such that at least one mounting hole (H4) arranged thereon is aligned with the second hole (H3) on the end of the fixing apparatus (FA) which is not connected to the assembly structure (AS), and the circuit board (5) is enabled to be mounted onto the fixing apparatus (FA) by means of a connection member (CM) such as a screw which is passed through the first hole (H3) and the second mounting hole (H4).
  • CM connection member
  • the circuit board is enabled to be fixedly mounted onto a mounting surface defined in a secure region in the body of the electrical household appliance.
  • connection members due to the need for aligning the holes through which the connection members are passed and the use of many connection members during the mounting process, the mounting time increases and thus, the production rate of the electrical household appliance decreases. Furthermore, overtightening the connecting members such as screws during the mounting process creates stress on the circuit board, causing the circuit board to be damaged over time.
  • a household appliance which has a circuit board which is mounted to a circuit board frame having a connection surface defined thereon.
  • the aim of the present invention is the realization of an electrical household appliance comprising a circuit board which can be mounted easily and securely.

  • the connection element By fixedly retaining the connection element by means of the holder, the body is prevented from moving on the mounting surface.
  • the through hole provided on the circuit board is fitted over the fixing member such that the circuit board is seated onto the resting surface, the circuit board seated onto the resting surface is fixedly retained between the resting surface and the fixing member.
  • connection members such as screws during the mounting of the circuit board into the appliance body
  • the circuit board is preferably mounted into the appliance body by being fixed from each edge thereof by using a plurality of fixing means.
  • the holder comprises two feet which are positioned so as to oppositely extend from the mounting surface along a plane which is almost perpendicular to the plane where the mounting surface extends, and a wall which extends between the ends of the feet which do not contact the mounting surface such that a gap with a certain width remains between the mounting surface and the wall.
  • the width of the gap between the mounting surface and the wall allows at least a portion of the connection element to be passed through said gap.
  • connection element comprises a tab which is fixed to the body from one end, which extends from said end such that there is a distance between the mounting surface and the tab almost in the plane where the mounting surface extends and at least one portion of which has a thickness allowing the same to be passed through the opening, and at least one protrusion which is provided almost at the end of the tab not connected to the body and which extends in the plane perpendicular to plane where the mounting surface extends.

  • the through hole on the circuit board is aligned with the protrusion and the through hole is fitted over the protrusion and the circuit board is seated onto the resting surface.
  • the circuit board While the through hole is fitted over the protrusion, as the width of the hole is narrower than the width of the head, the walls of the circuit board which surround the hole exert force onto the head and causes the head to become narrower thanks to the the flexible structure of the head. After the hole is completely fitted over the head, the circuit board is seated on the resting surface and the head returns to the original state, wherein the total width of the same is greater than that of the hole as soon as the force exerted thereon is removed. In this case, the circuit board is enabled to be fixedly retained on the resting surface so as to be positioned between the resting surface and the head.

  • the fixing member is in the form of an arrow which is formed by the protrusion and the wings.
  • a gap with a certain width is formed between the wings and the protrusion. While the through hole is fitted over the head, the force applied on the wings by the walls of the circuit board which surround the through hole moves the wings towards the protrusion for a certain amount.
  • the through hole is enabled to be easily fitted over the head which has a reduced total width.
  • the circuit board is seated on the resting surface and as the force exerted on the wings is removed, the wings move away form the protrusion for a certain amount.
  • the head is produced in an easy and cost-effective manner.
  • the fixing means further comprises at least one arm which is fixed to the body at one end and which extends from said end so as to contact the mounting surface in the same plane and the same direction with the tab so as not to contact the tab.
  • said arm preferably has a thickness which allows passage through the opening.
  • the fixing means comprises two arms which are positioned symmetrically with respect to the tab. As said arm contacts the mounting surface, the former enables the body and hence the fixing means to be kept more stable on the mounting surface.
  • the fixing means is produced from plastic.
  • the fixing means is enabled to be processed and shaped easily during the production process and thus, the production speed is increased and cost effectiveness is provided.
  • the present invention by mounting the circuit board comprising the circuit elements at least controlling the operation of the electrical household appliance onto a suitable mounting surface defined in the appliance body by using the fixing means, the need for using any connection member such as screws is eliminated and thus, the time spent for the mounting process is decreased and the circuit board is prevented from being damaged due to the stress formed as a result of the force applied onto the circuit board by the connection member.
