Definitions

  • the present invention relates to a domestic appliance, especially a dishwasher, which is a household electrical appliance used mostly in houses and restaurants.
  • the dishwasher is able to wash the dishes automatically based on a proper schedule and by spraying hot water mixed with strong detergents on the dishes.
  • Household dishwashers may comprise a tub wherein the dishwashing is done, one or more baskets to hold various types of dishes to be washed placed inside the tub, a washing arm to provide hot water mixed with strong detergents for the dishes on each basket, a conduit to deliver the water to the washing arm, and a circulation pump to pump the water to the conduit.
  • the washing arm may include one or more spray tube with a plurality of nozzle units adjusted to direct water jets towards the basket and spray the water on the dishes.
  • the corresponding washing arm for each basket may be located beneath the basket.
  • the topmost or the third one has the lowest height and is mostly used for cutlery.
  • the corresponding washing arm for the upper basket may be located above the basket, and the corresponding washing arm for the middle and lower baskets may be located beneath the baskets.
  • the washing arms are mostly illustrated as rotating washing arms, but the position and the type of the washing arms are not limited to the mentioned position and type.
  • dishwashers are usually 82 cm tall, and this height is accepted as the standard size all over the world.
  • the tub is 5 cm longer than the tub in the normal-sized dishwashers, and they are called “tall tubs.”
  • different kinds of dishes such as cups, glasses, and plates, can be placed in all baskets, especially in the third one, so the dishwasher has more volume for more dishes.
  • the invention with the publication number W003051171 Al, relates to a system for delivering water from a pipeline to a washing arm in a basket.
  • the basket is configured without any mobile spray devices and the items to be cleaned are sprayed via stationary spraying devices with nozzle-like outbreaks. But the water spray direction is straight and not all corners of the basket is covered with the sprayed water.
  • the invention of publication US10349804B2 relates to a second dish rack having a sloping, stepless bottom wall with a washing arm located below the bottom wall of the dish rack.
  • a washing arm located below the bottom wall of the dish rack.
  • this slope in the basket causes dirty water to accumulate. Therefore, this system also needs to be improved.
  • Household dishwashers may comprise a tub wherein the dishwashing is done, one or more baskets to hold various types of dishes to be washed placed inside the tub, a washing arm to provide hot water mixed with strong detergents for the dishes on each basket, a conduit to deliver the water to the washing arm, and a circulation pump to pump the water to the conduit.
  • the washing arm may include one or more spray tube with a plurality of nozzle units adjusted to direct water jets towards the basket and spray the water on the dishes.
  • the corresponding washing arm for each basket may be located beneath the basket.
  • the aim of the present invention is to wash cleanly all dishes which are placed in the baskets in all comers. That is because the nozzle units which are located on the washing arms are configured in a predetermined shape and angle such that the water reaches to all corners of the basket. On the other hand, the amount of water that comes out from the nozzle units are kept at an economical level with equal pressure.
  • the design of the washing arm is such that the wasted space in the third basket is minimized, because there is not any rotating washing arm for the basket, and its position does not extend below the limit of the lower surface of the third basket. Thus, there is no loss of height between the second basket and the third basket so more volume is provided for bigger dishes to put on these baskets.
  • the third advantage is that the spray tube is configured with a thinner thickness instead of a round tube, minimizing the loss in the internal height of the spray tube compared to the known art.
  • the washing arm is embedded in the area that is occupied by the basket. Due to the shape of the cross section of the spray tubes, the washing arms are placed right in grooves of the bottom of the basket. So, less space is occupied by the washing arm.
  • Figure 1 is an internal view of the dishwasher.
  • Figure 2 is a top perspective view of the third basket.
  • Figure 3 is a side perspective view of the basket and the corresponding conduit.
  • Figure 4 is a side view of the third basket and the corresponding conduit.
  • Figure 5 is a right-top perspective view of the washing arm.
  • Figure 6 is a left-top perspective view of the washing arm.
  • Figure 7 is a bottom view of the washing arm.
  • Figure 8 is a detailed view of a nozzle unit.
  • Figure 9 is a cross-sectional view of the washing arm.
  • Figure 10 shows an oblique and right cone.

  • the washing arms may be fixed to the baskets.
  • the presented washing arm (1) is located under the third basket (4) to wash the dishes on the third basket (4); although the presented washing arm may be utilized for the first and second baskets as well.
  • FIG 2 shows the third basket (4) and the corresponding washing arm (1)
  • figures 3 and 4 show the conduit (5) which leads the water to the washing arm (1).
  • the washing arm (1) which is shown in figure (5) may comprise at least one manifold (16) and at least one spray tube (10) which protrudes from the manifold (16).
  • the washing arm (1) comprises three parallel spray tubes called first spray tube (10), second spray tube (11), and third spray tube (12), positioned at a certain distance from each other in a fork form.
  • the present embodiment does not limit the scope of the invention and the number of tubes, manifolds and the position of the spray tubes and nuzzle units may change based on the technical demand.
  • the spray tubes may cross each other and there may be less or more spray tubes that protrudes from the manifold.
  • each spray tubes (10,11,12) protrude from the manifold (16).
  • the cross section of each spray tubes (10,11,12) may be in form of a circle sector or a polygon.
  • the cross section of the spray tube is a sector of circle (17) which is shown in figure 9.
  • a plurality of nozzle units (13) is embedded on the upper edges of the spray tubes (17).
  • the nozzle units (13) perform as a means to spray the water on the dishes in predetermined directed angles.
  • the nozzle units (13) may be located such that they face to the third basket (4).
