Description

    A DISHWASHER COMPRISING SPRAYING MEMBER
  • The present invention relates to a dishwasher comprising spraying member.
  • In dishwashers, the washing process is performed by spraying water coming through a main supply line on the dishes by means of spray arms. Spraying members provided on the spray arm enable water to be sprayed on the dishes with a certain pressure. The flow rate and the pressure of the sprayed water is of utmost importance in terms of cleaning the dishes. Washing regions are formed in dishwashers to clean intense dirtiness. Additional spraying members are used in washing regions to enable cleaning such dirtiness. Kitchenware placed on a basket are cleaned by means of water pressure and detergent. Therefore, arrangement of dishes on a basket is of utmost importance to achieve high efficiency in the washing process. Particularly kitchenware which are tall and have a narrow mouth such as bottles and glasses are not enabled to contact water and are therefore not cleaned sufficiently. Various placement apparatuses are used in dishwashers for this purpose. However, placement apparatuses occupy additional space and decrease the available volume of a basket. Such placement apparatuses hinder placement when not in use.
  • State of the art United States patent application document no. US2977963 discloses a washing machine having intense washing regions.
