Definitions

  • the present invention relates to a dishwasher whose mechanical characteristics are improved.
  • washing is performed by spraying water coming through a main supply line on the dishes by means of spray arms.
  • the spray arms rotate about themselves in separate revolutions and speeds for homogeneous spraying of water on all dishes in the dishwasher.
  • a spray arm is mounted on a water supply line with various coupling members. Coupling members are constructed to enable spray arms to rotate about themselves.
  • the spray arms have a structure attachable and detachable on the water supply line for a user to easily clean the spray arm and to change the coupling members when required. Therefore, the structure of coupling members has to be easily attachable and detachable.
  • a washer with a low friction coefficient and a high thermal and mechanical strength is used between the coupling members for the spray arm to rotate for longer durations at high speeds.
  • the aim of the present invention is to realize a dishwasher whose mechanical characteristics are improved.
  • the dishwasher realized to achieve the aim of the present invention and disclosed in the first claim and the dependent claims comprises a body, a washing tub in which items to be washed are placed, at least one spray arm enabling washing of the items by spraying water in the washing tub and a water supply line conveying water to the spray arm. Water is conveyed to the washing tub from the main supply line by means of the water supply line. Water reaching from the water supply line to the spray arm is transferred to the items placed in the washing tub by being sprayed.
  • the dishwasher of the invention comprises at least one coupling member enabling connection between the spray arm and the water supply line.
  • the coupling member is made of a material with high thermal and mechanical strength. By this, the coupling member is prevented from being deformed due to the motion of the spray arm.
  • the coupling member comprises high density polyethylene material.
  • the coupling member comprises polyoxymethylene material.
  • the coupling member comprises material of polyoxymethylene and polytetraflouroethylene combination.
  • the dishwasher comprises a centering member mounted on the spray arm and a fixing member mounted on the water supply line.
  • the centering member is stably mounted on the spray arm so as to rotate about itself over the water supply line.
  • the fixing member is stably mounted on the water supply line.
  • the fixing member bears the centering member, and together with the centering member bears the spray arm.
  • the centering member and the fixing member are a coupling member.
  • the dishwasher comprises a sealing gasket mounted on the centering member.
  • the coupling member is integral with the spray arm.
  • the coupling member is integral with the water supply line.
  • Figure 1 is a perspective view of the dishwasher.
  • Figure 2 is a perspective view of the spray arm.
  • Figure 3 is an exploded view of the coupling member.
  • the dishwasher (1) comprises a body (2), a washing tub (3) in which washing is performed, at least one spray arm (4) arranged on the washing tub (3), enabling spraying of water in the washing tub (3) by rotating about itself, and a water supply line (5) conveying water it receives from the main supply line to the spray arm (4). Water conveyed by means of the water supply line (5) to spray arm (4) is transferred to the washing tub (3). The items placed in the washing tub (3) are washed by high revolution rotation of the spray arm (4) about itself. ( Figure 1)
  • the dishwasher (1) of the invention comprises at least one coupling member (6) comprising polymer material, enabling connection between the spray arm (4) and the water supply line (5).
  • the spray arm (4) rotates about itself by being fixed on the water supply line (5).
  • the coupling member (6) between the spray arm (4) and the water supply line (5) is made of polymer material with high thermal and mechanical strength.
  • the coupling member (6) comprises high density polyethylene (HDPE) material.
  • High density polyethylene material has a high thermal and mechanical strength. By this, the coupling member (6) is enabled to have a long service life.
  • high density polyethylene material has a self-lubricating quality. By this, friction between the coupling members (6) is reduced to a minimum and the spray arm (4) is enabled to rotate easily.
  • the coupling member (6) comprises polyoxymethylene (POM) material.
  • POM polyoxymethylene
  • Polyoxymethylene is a material capable of enabling high elasticity, with good mechanical strength and abrasion resistance. By this, it can be used for long periods of time without being deformed by the motion of the spray arm (4). In addition, since it has good elasticity, it can damp the motions of the spray arm (4) without transmitting them to the water supply line (5).
  • the coupling member (6) comprises material of polyoxymethylene and polytetraflouroethylene (PTFE) combination. Since it is a material with high friction resistance, it can be used for long periods of time without being deformed.
  • PTFE polytetraflouroethylene
  • the dishwasher (1) comprises a centering member (7) mounted on the spray arm (4), enabling the spray arm (4) to be mounted on the water supply line (5) and to rotate about itself, a fixing member (8) mounted on the water supply line (5), contacting the centering member (7), and a coupling member (6) which is the fixing member (8) and/or the centering member (7).
  • the centering member (7) can be fixed by being mounted on the spray arm (4). It is rotatably mounted on the water supply line (5). By this, it enables the spray arm (4) to rotate.
  • the fixing member (8) bears the centering member (7) and is fixed by being mounted on the water supply line (5).
  • the centering member (7) and the coupling member (6) are in continuous contact during rotation of the spray arm (4). Friction and deformation to be generated between the centering member (7) and the fixing member (8) is reduced thanks to them being made of a material with high thermal and mechanical strength. Reduction of friction and deformation is accomplished without using a member such as washer between the centering member (7) and the fixing member (8). By this, the spray arm (4) is easily detached and attached by the user. Production is facilitated as the duration of mounting is decreased. ( Figure 3)
  • a dishwasher (1) whose mechanical characteristics are improved is realized with the present invention.
  • Product durability is enhanced thanks to the coupling members (6) arranged between the spray arm (4) and the water supply line (5) being made of material with high thermal and mechanical strength.
  • the spray arm (4) is enabled to rotate for long periods of time. Using members decreasing friction between the coupling members (6) is not required. Ease of mounting is thus provided.
