Description

The present invention relates to a dishwasher comprising a filter.
In dishwashers, dirt and stains on the dishes are removed by means of the spraying arms which spray water. Dirt dispersing into the washing tub is filtered by means of the strainer provided at the base of the dishwasher. Thus, dirt is prevented from entering the water line and clogging the line. The strainer is detachably mounted onto the base of the dishwasher. Thus, the strainer can be easily detached by the user to be washed and cleaned. Dirt smaller than the holes of the strainer is held by a filter which has smaller holes and which is detachably mounted onto the strainer. A micro filter which retains even smaller dirt particles is attached to the filter. The filter and the micro filter collect dirt particles thereon in the course of time and are required to be detached and washed by the user. In order to ensure that the washing performance is high, the filter and the micro filter are detached from the dishwasher and replaced by the user. However, dirt accumulating on the filter causes a bad appearance and bad odor in the dishwasher. Moreover, there may be situations where the filter and micro filter cannot be properly attached in place in the dishwasher during the assembly. Sometimes, the user continues the washing process without realizing that the filter and micro filter are dirty, and problems such as dirt sticking to kitchen items arise.
In the state of the art International Patent Application No. WO2019068528 , a dishwasher is disclosed, which enables the micro filter to be washed by creating a vortex in the sump.
The aim of the present invention is the realization of a dishwasher comprising a sump which enables the filter and the micro filter to be washed.
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; a filtering member which is provided on the base of the washing tub; and a filter which is detachably attached to the filtering member. The filter has a fine filter, which retains smaller particles, and a coarse filter, which retains larger particles. By means of the filter, the dirt particles which are removed from over the kitchen items during the washing are retained and are prevented from reaching the sump. Thus, the dirt particles are prevented from reaching electronic components and from adversely affecting the washing performance.
The dishwasher of the present invention comprises a delivery line which almost surrounds the inner wall of the sump and a plurality of openings which enable water to be delivered from the delivery line to the fine filter. The water is enabled to be guided by means of the delivery line arranged on the inner wall of the sump. By means of the openings provided on the delivery line, the water is delivered to the filter. Thus, the filter is washed.
In an embodiment of the present invention, the dishwasher comprises the delivery line having a channel which enables the water taken from the mains to be delivered to the delivery line, and an inlet opening which is provided on the sump. By means of the channel, the water is delivered to the delivery line. The channel is disposed on the inlet opening provided on the sump. Thus, the water is enabled to be delivered to the delivery line.
In an embodiment of the present invention, the dishwasher comprises the opening which is inclined so as to enable the water to be delivered to the filter. The openings enable the water in the delivery line to be guided so as to reach the filter. The openings are configured to be inclined from the delivery line to the filter.
In an embodiment of the present invention, the dishwasher comprises the delivery line which is detachably attached onto the inner wall of the sump. The delivery line can be detachably attached onto the sump, which enables the former to be easily cleaned
In an embodiment of the present invention, the dishwasher comprises a housing which is arranged almost all around the inner wall of the sump and whereon the delivery line is attached. The delivery line is attached to and placed on the sump by means of the housing. Thus, the water can be delivered through the delivery line.
By means of the present invention, a dishwasher is realized, wherein the filter extending into the sump is enabled to be washed with the water delivered to the sump.
A dishwasher realized in order to attain the aim of the present invention is illustrated in the attached figures, where:
