Description

The present invention relates to a dishwasher which provides intensive washing.
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 International Patent Application No. WO2005065519 , a dishwasher comprising an intensive washing region is disclosed.
In the state of the art United States Patent Application No. US3064661 , a dishwasher comprising a dual cycle, preselectable in accordance with the soil condition of the articles to be cleaned, is disclosed.
In the state of the art German Patent Application No. DE102015103128 , a dishwasher is disclosed having a sprayer that is provided on racks, and is positioned to spray a treating liquid onto dishes received by the rack. The sprayer and a movable extension are provided with two liquid openings. The extension is moved between one position in which the treating liquid flows through one liquid opening into a treating chamber and does not flow through another liquid opening, and another position in which the treating liquid flows through another liquid opening into the treating chamber.
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. Thus, the cleaning process is performed. An intensive washing member is provided on the rack. Kitchen items with greater depth such as bottles and glasses are placed onto the intensive washing member. The water is delivered to the intensive washing member by means of an intensive washing line.
The dishwasher of the present invention comprises at least one water outlet port which is provided on the intensive washing member and a guiding member which has a guiding surface onto which the water passing through the water outlet port is delivered. Water is sprayed onto the washing tub through the intensive washing member by means of the water outlet port. The water delivered through the water outlet port hits the guiding surface. Thereby, the water is redirected and sent towards the dishes placed on the intensive washing member.
According to the present invention, the dishwasher comprises the guiding member having the guiding surface which enables the direction of the water delivered through the water outlet port to be changed by approximately 90 degrees. The inclination of the guiding surface is configured to change the direction of the water by approximately 90 degrees.
In an embodiment of the present invention, the dishwasher comprises an arrangement member which is disposed in front of the intensive washing member and whereon the kitchen items such as glasses and bottles are placed. The guiding member is detachably attached onto the arrangement member.
In an embodiment of the present invention, the dishwasher comprises a water delivery line which is attached to the water outlet port and an additional spraying member which can be attached to and detached from the water delivery line. The water delivery line enables the water to be delivered through the water outlet port. One end of the water delivery line is arranged on the water outlet port. The other end thereof is connected to the additional spraying member.
In an embodiment of the present invention, the dishwasher comprises the additional spraying member in the form of a cone. By means of the conical form of the additional spraying member, the pressure of the water delivered into the washing tub is increased.
In an embodiment of the present invention, the dishwasher comprises the additional spraying member which is perpendicular to the water delivery line. The additional spraying member is attached so as to be perpendicular to the water delivery line.
In an embodiment of the present invention, the dishwasher comprises the water delivery line having an open position and a closed position. The water delivery line is parallel to the base of the rack in the open position and the water is delivered through the additional spraying member. The water delivery line shifts to the closed position by turning upwards on the water outlet port. When the water delivery line is in the closed position, the water is not delivered through the additional spraying member. The water delivery line shifts to the closed position when the intensive washing member is not in use. Thereby, the water delivery line and the additional spraying member are prevented from occupying space on the rack.
In an embodiment of the present invention, the dishwasher comprises a valve which prevents the water from being delivered through the spraying member when the water delivery line is in the closed position. When the water delivery line is rotated on the water outlet port, the delivery of water is prevented by means of the valve.
By means of the present invention, a dishwasher with increased washing efficiency is realized. By means of the intensive washing member, the items which are extremely dirty or narrower items such as glasses and bottles placed on the rack can be cleaned effectively.
A dishwasher realized in order to attain the aim of the present invention is illustrated in the attached figures, where:
