Description

A DISHWASHER COMPRISING AN ADDITIONAL SPRAYING MEMBER
The present invention relates to a dishwasher comprising an additional spraying member.
In dishwashers, the washing process is realized by spraying the water received from the main delivery line onto the dishes by means of spray arms. The spraying members provided on the spray arm enable the water to be sprayed onto the dishes at a certain pressure. The flow rate and pressure of the sprayed water are critical in terms of cleaning of the dishes. In the dishwashers, washing areas are formed to clean heavy stains. Additional spraying members are used to clean the stains in the washing areas. The kitchen items placed onto the rack are cleaned with water pressure and detergent. Therefore, the layout of the dishes on the rack is important to perform a highly-efficient washing process. Especially tall kitchen items such as bottles and glasses with a narrow mouth cannot contact water and thus, cannot be cleaned. Therefore, a plurality of arrangement apparatuses are used in dishwashers. However, the arrangement apparatuses occupy additional space and decrease the usable volume of the rack. When not in use, the arrangement apparatuses prevent the proper arrangement.
In the state of the art United States of America Patent Application Document No. US2977963, a washing machine is disclosed, comprising intensive washing sections. The aim of the present invention is the realization of a dishwasher with improved washing effectiveness.
The dishwasher realized in order to attain the aim of the present invention, explicated in the first claim and the respective claims thereof, comprises a body; a washing tub which is disposed in the body, wherein the washing process is performed; at least one rack which is disposed in the washing tub; and at least one spraying member which sprays water onto the racks. The kitchen items to be washed are placed onto the rack. The water is delivered onto the dishes by means of the spraying member. Consequently, the cleaning process is performed. An additional spraying member is provided on the rack. Kitchen items with greater depth such as bottles and glasses are placed onto the additional spraying member. Thus, kitchen items with greater depth are enabled to be easily cleaned.
The dishwasher of the present invention comprises the additional spraying member having an inner pipe, an outer pipe and at least one fixed spraying means and at least one movable spraying means which are disposed on the inner pipe. The outer pipe is positioned around the inner pipe so as to at least partially surround the inner pipe. The fixed spraying means and the movable spraying means provide the delivery of water.
In an embodiment of the present invention, the dishwasher comprises the additional spraying member having a first position and a second position. When the additional spraying member is in the first position, the outer pipe moves upwards by sliding over the inner pipe. The movable spraying means also move upwards together with the outer pipe. Thus, the movable spraying means enable the kitchen items to be easily cleaned. When the additional spraying member is in the second position, the movable spraying means are parallel to the fixed spraying means. Thus, intensive washing is performed. In an embodiment of the present invention, the dishwasher comprises a sealing member which is positioned between the movable spraying means and the outer pipe. The sealing member completely surrounds the movable spraying means. Thus, the sealing member enables the movement of the outer pipe to be transmitted to the spraying means.
In an embodiment of the present invention, the dishwasher comprises the sealing member which is produced from a flexible material. Thus, the sealing member can move in various directions.
In an embodiment of the present invention, the dishwasher comprises a claw and a housing wherein the claw is seated, which are respectively disposed on the outer pipe and the inner pipe and which together enable the inner pipe and the outer pipe to be interlocked in the first position and the second position. As the claw engages with the housing, the inner pipe and the outer pipe interlock in the first position and the second position. In an embodiment of the present invention, the dishwasher comprises a slot which is arranged on the outer pipe. The fixed spraying means pass through the slot so as to extend into the washing tub.
In an embodiment of the present invention, the dishwasher comprises an opening which is arranged on the upper surface of the outer pipe. By means of the opening, the water is directly delivered to the bases of the kitchen items.
By means of the present invention, a dishwasher with increased washing efficiency is realized. By means of the fixed and movable spraying means, kitchen items with different sizes can be washed.
