Description

The present invention relates to a dishwasher which is illuminated by means of at least one illumination member disposed in the washing tub.
In dishwashers, various types of illumination members are placed on the walls of the washing tub to illuminate the interior of the washing tub. The washing tub is an environment which is in constant contact with water and water vapor during the placing of the dishes and the washing of the dishes. Therefore, the impermeability of the walls of the washing tub is very important. Especially in washing tubs where illumination members are placed on the wall, it is necessary to pay attention to providing proper water tightness to the volume where the illumination member is disposed and to the outside of the washing tub, and to providing proper water tightness equally on all surfaces. In the state of the art, sealing is achieved by rotating the back part and squeezing the gasket between the front part and the rear part.
In the state of the art, in order to provide wide and rectangular sealing in the washing tub, the gasket must be squeezed equally on all surfaces to ensure sealing. Even if the gasket is pulled with a screw or claw, the continuity of the desired sealing cannot be achieved since the surface between two claws or between two screws is long.
In the state of the art Chinese Utility Model Document Application No. CN207734123 , a dishwasher is disclosed, comprising a circular light source which is disposed on the upper wall of the washing tub.
In the state of the art Chinese Utility Model Document Application No. CN210871409 , an illumination member is disclosed, which is disposed at the inner side of the door of the dishwasher.
The aim of the present invention is the realization of a dishwasher which is illuminated by means of at least one illumination member disposed in the washing tub.
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 first transparent lid which is disposed on the side of cut-out facing the inside of the body; a sealing member which is disposed between the first lid and the body; and a second lid which enables the force to be applied to the body such that the sealing member remains between the first lid and the body. Thus, the sealing member is squeezed evenly on all surfaces between the first lid and the body, thereby providing sealing effectively.
In the embodiments of the present invention where a quadrangular and large surface first lid is used, the sealing member is effectively squeezed, thus providing sealing on a larger contact surface.
The light emitted by the illumination member disposed behind the first lid reaches the inside of the body and illuminates the inside of the body. The illumination member can be used for illumination purposes and for hygiene purposes.
In an embodiment of the present invention, the dishwasher comprises a quadrangular sealing member which is completely seated onto the housing between the base and the body, which, at the center thereof, has a gap in a form matching that of the cut-out and a skirt surrounds the cut-out. When the sealing member is mounted on the housing on the first lid and seated on the cut-out, the sealing member is squeezed between the body and the base and the skirt surrounds the wall of the cut-out. Thus, formation of any gap between the cut-out and the body whereon the first lid is seated is prevented and a complete sealing is ensured.
In an embodiment of the present invention, the first lid is positioned such that the long side thereof extends along the horizontal plane.
In the preferred embodiment of the present invention, the first lid is positioned such that the long side thereof extends along the vertical plane.
In the preferred embodiment of the present invention, the second lid is composed of two equal half parts. Thus, in an embodiment wherein a quadrangular first lid is used, the sealing member is enabled to be squeezed in the most effective manner. The two parts forming the second lid can move towards each other in the horizontal plane and can move towards each other in the vertical plane, thus enabling the sealing member to be squeezed. The position of the two parts varies according to the positioning of the first lid in the horizontal or vertical plane. The first and second parts are actually two identical half parts, and in the preferred embodiment, where the first and second parts are attached onto the guide, the first and second parts are driven towards each other from the bottom and the top and bear against each other by moving on the guide. In this case, the first and second parts completely wrap the guide from the bottom, top and sides, and the second lid is attached to the first lid.
In the preferred embodiment of the present invention, the first part is mounted on the first lid such that the first set engages with the guide from the bottom and the first abutment surface fully bears against the side wall of the guide. The first set is driven on the guide and pushed upwards and the movement of the first part ends when the lower edge of the first set bears against the lower edge of the guide. Thus, the first part is attached to one half of the first part. In this embodiment, the first abutment surface is completely seated onto the side and bottom wall of the guide and compresses the part of the first lid where the first part is attached towards the body such that the sealing member remains therebetween.
In the preferred embodiment of the present invention, the second part is mounted on the first lid such that the second set engages with the guide from the top and the second abutment surface fully bears against the side wall of the guide. The second set is driven on the guide and pushed downwards and the movement of the second part ends when the upper edge of the second set bears against the upper edge of the guide. Thus, the second part is attached to one half of the first part. In this embodiment, the second abutment surface is completely seated onto the side and bottom wall of the guide and compresses the part of the first lid where the second part is attached towards the body such that the sealing member remains therebetween. In this case, the second part bears against the first part as well, and the second part is seated on the other half of the first lid, thus enabling the second lid to be fully attached to the first lid. Thus, the first lid is pulled towards the body by means of the second lid such that the sealing member remains therebetween, enabling the sealing member to be fully squeezed along the first and second abutment surfaces.
In the preferred embodiment of the present invention, the sealing member is seated into the housing on the first lid. Then, the first lid with the sealing member attached thereon is attached to the cut-out on the body wall. When the first lid is attached to the cut-out, the sealing member is positioned between the base and the body, and the skirt surrounds the wall of the cut-out. Moreover, the guide passes to the other side of the cut-out to be positioned between the body and the casing. Then, the first part is mounted on the first lid such that the first set engages with the guide from the bottom and the first abutment surface fully bears against the side wall of the guide. The first set is driven on the guide and pushed upwards until the lower edge of the first set bears against the lower edge of the guide. When the lower edge of the first set bears against the lower edge of the guide, the movement of the first part on the first lid ends. In this case, the first abutment surface is completely seated onto the side and bottom walls of the guide and compresses the part of the first lid where the first part is attached towards the body such that the sealing member remains therebetween. Afterwards, the second part is mounted on the first lid such that the second set engages with the guide from the top and the second abutment surface fully bears against the side wall of the guide. The second set is driven on the guide and pushed upwards until the upper edge of the second set bears against the upper edge of the guide. When the upper edge of the second set bears against the upper edge of the guide, the second part bears against the first part and the movement of the second part on the first lid ends. In this case, the second abutment surface is completely seated onto the side and bottom wall of the guide and compresses the part of the first lid where the second part is attached towards the body such that the sealing member remains therebetween. At the same time, the second locking member on the second part is locked to the first locking protrusion on the first part, and the first locking member on the first part is locked to the second locking protrusion on the second part, and the second lid is squeezed on the first lid such that the sealing member remains between the body and the first lid. Thus, the first lid is pulled towards the body by means of the second lid such that the sealing member remains therebetween, enabling the sealing member to be fully squeezed along the first and second abutment surfaces without any gap therebetween.
By means of the present invention, the quadrangular first lid is enabled to be mounted on the body by providing an effective sealing. The sealing member is squeezed and crushed in a complete and homogeneous manner along the entire surface in the assembly area. Thus, the sealing of the dishwasher is improved, and safety and quality are increased. Moreover, since screws and similar fixing members are not used, both cost and time savings are provided.
