Definitions

  • the present invention relates to a dishwasher comprising spray arm.
  • the washing process is performed by spraying water coming through a water supply line on the dishes by means of spray arms. Water is sprayed on the surfaces of the dishes placed on a basket through a spray arm.
  • the spray arms rotate about themselves in different revolutions and speeds for homogeneous spraying of water on all dishes in the dishwasher. Water is thus enabled to be angularly transmitted on the dishes. Water can reach more regions as its intensity and speed increase. Washing performance is thus enhanced.
  • water transmitted from the spray arms fails to reach the dishes due to a high amount of dishes or the dishes not being placed well enough, and washing performance decreases. Increasing the amount and flow rate of water in order to enhance washing performance leads to a higher energy and/or water consumption.
  • EP0962181 discloses a dishwasher comprising a spray arm capable of angular motion by means of a magnetic positioning system.
  • the aim of the present invention is to realize a dishwasher with enhanced washing performance.
  • 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 enabling conveying water to the spray arm.
  • the spray arm is detachably attached to the water supply line by means of a coupling mechanism. Water is conveyed to the washing tub through the water supply line by means of the water supply line. Water reaching through the water supply line to the spray arm is conveyed to the items placed in the washing tub by being sprayed.
  • the dishwasher of the invention comprises a coupling mechanism having a bearer member and a rotatable member.
  • An end of the bearer member is mounted to the water supply line and the other end to the spray arm.
  • the spray arm is connected to the water supply line by means of the bearer member, enabling water transmission through the water supply line to the spray arm.
  • the rotatable member is mounted on the bearer member.
  • the rotatable member rotates about its axis upon rotation of the spray arm. At least one first peak and at least one first dip are provided on the surface of the bearer member contacting the rotatable member. At least one second peak and at least one second dip are provided on the surface of the rotatable member contacting the bearer member.
  • the bearer member and the rotatable member move away from each other by means of the peaks and approach each other by means of the dips.
  • a spring is provided on the bearer member, enabling the rotatable member to be continuously pushed upwards.
  • the spring enables the second peak and/or the second dip on the rotatable member to continuously contact the first peak and or the first dip provided on the bearer.
  • the spray arm is thus enabled to continuously move in vertical direction. The motion of the spray arm in vertical direction enables the sprayed water to reach a wider area. Washing performance is thus enhanced.
  • the dishwasher comprises a spray arm having an upper position in which the first peak provided on the bearer member meets the second dip provided on the rotatable member or in which the second peak provided on the rotatable member meets the second dip provided on the bearer member, and a lower position in which the first peak provided on the bearer member meets the second peak provided on the rotatable member.
  • the dishwasher comprises a lock which can be controlled by the user.
  • the lock comprises a recess provided all around the rotatable member and a track provided all around the bearer member. The recess extends along the track.
  • Figure 1 is a perspective view of the dishwasher.
  • Figure 2 is a perspective view of the water supply line and the spray arm.
  • Figure 3 is a perspective view of the bearer member.
  • Figure 4 is a perspective view of the rotatable member.
  • Figure 5 is a schematic view of the coupling mechanism with the spray arm in lower position.
  • Figure 6 is a schematic view of the coupling mechanism with the spray arm in upper position.
  • the dishwasher (1) comprises a body (2), a washing tub (3) in which the washing process is performed, at least one spray arm (4) arranged on the washing tub (3), enabling spraying water in the washing tub (3) by rotating about itself, a water supply line (5) conveying water it receives through the mains to the spray arm (4), and a coupling mechanism (6) provided between the water supply line (5) and the spray arm (4), enabling the spray arm (4) to be mounted on the water supply line (5). Water coming through the water supply line (5) is sprayed on the dishes by means of the spray arm (4), thereby enabling performing the washing process.
  • the spray arm (4) is detachably attached on the water supply line (5) by means of the coupling mechanism (6).
  • the dishwasher (1) of the invention comprises a coupling mechanism (6) enabling the spray arm (4) to move in vertical direction and having a bearer member (7) whose one end is connected to the water supply line (5) and the other end to the spray arm (4), a rotatable member (8) mounted on the bearer member (7) so as to be rotatable on the bearer member (7), at least one first peak (9) and at least one first dip (10) provided on the surface of the bearer member (7) contacting the rotatable member (8), at least one second peak (11) and at least one second dip (12) provided on the surface of the rotatable member (8) contacting the bearer member (7), and a spring (13) provided on the bearer member (7), enabling the rotatable member (8) to be pushed upwards when the rotatable member (8) is mounted on the bearer member (7).
  • the rotatable member (8) is rotatably mounted on the bearer member (7). Dips (10, 12) and peaks (9, 11) are provided on the bearer member (7) and the rotatable member (8). The distance between the bearer member (7) and the rotatable member (8) varies by means of the dips (10, 12) and the peaks (9, 11). The bearer member (7) and the rotatable member (8) approach and move away from each other. The spray arm (4) thus moves in vertical direction.
  • the spring (13) enables the rotatable member (8) to be continuously pushed towards the bearer member (7).
  • the bearer member (7) and the rotatable member (8) are thus enabled to continuously contact each other. Movement of the spray arm (4) in vertical direction enables the sprayed water to reach a wider dirty area, enhancing washing performance.
  • the dishwasher (1) comprises a spray arm (4) having an upper position (U) in which the first peak (9) or the first dip (10) provided on the bearer member (7) meets the second dip (12) or the second peak (11) provided on the rotatable member (8), and a lower position (A) in which the first peak (9) provided on the bearer member (7) meets the second peak (11) provided on the rotatable member (8).
  • the spray arm (4) is farther from the dishes when it is in the upper position (U). Taller dishes are thus enabled to be cleaned.
  • the spray arm (4) assumes the lower position (A), water is enabled to be transmitted to smaller kitchenware resting in between other items.
  • the dishwasher (1) comprises a lock (16) which can be controlled by the user, enabling the spray arm (4) to not move in vertical direction, having a track (14) provided all around the rotatable member (8), and at least one projection (15) provided on the bearer member (7), advancing along the track (14).
  • the projection (15) settles on the track (14) and the spray arm (4) only rotates about its axis without moving in vertical direction.
  • the invention enables realizing a dishwasher (1) with enhanced washing performance.
  • the coupling mechanism (6) enabling the spray arm (4) to be connected to the water supply line (5), comprises a bearer member (7) and a rotatable member (8).
  • the rotatable member (8) moves in vertical direction on the bearer member (7) by means of the peaks (9, 11) and the dips (10, 12) provided on the surfaces of the rotatable member (8) and the bearer member (7) contacting each other.
  • This enables the spray arm (4) also to move in vertical direction. Water is transmitted to more kitchenware by means of the spray arm (4) moving in vertical direction. Washing performance is thus enhanced.
