Description

The present invention relates to a dishwasher comprising a protective member.
In dishwashers, the washing process is performed in the washing tub. The washing tub is isolated from the outer environment by means of a door. In the dishwasher, the door is opened by rotating on the horizontal axis such that the lower edge thereof remains fixed on the body. The door is perpendicular to the floor of the environment in the closed position, and parallel to the floor of the environment in the fully open position. Today, the use of built-in dishwashers is known. The built-in dishwashers are placed in the kitchen furniture and decorative panels compatible with the kitchen furniture are attached onto the door. Thus, the dishwasher is completely hidden in the kitchen and an aesthetic appearance is provided. The decorative panels attached onto the door are selected by the user and mounted on the dishwasher by service staff. The decorative panel attached onto the dishwasher door varies depending on the kitchen structure and the design of the cabinets. In the state of the art, there are door support mechanisms suitable for various decorative panels. It is known that flexible members and ropes are used in said mechanisms. The moving members used on the mechanism pose a danger to users during the opening and closing of the door.
In the state of the art Patent Document No. EP2276387 , a dishwasher is disclosed, comprising a lid mounted on the hinge arm for sound blocking purposes.
The aim of the present invention is the realization of a dishwasher comprising a door opening mechanism with improved safety.
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 provided on the body; a door which enables the washing tub to be isolated from the outer environment; a hinge which enables the door to be connected to the body; a hinge arm connected to the hinge; and at least one pulley provided under the hinge arm. The kitchen items to be washed are placed into the washing tub. The door is closed such that the washing tub is isolated from the outer environment and the washing process is enabled to be performed. The door is connected onto the body by means of a hinge via the lower edge thereof. The door opens by rotating around the horizontal axis as connected to the body via the lower edge thereof, and the upper edge thereof moves away from the body.
The dishwasher of the present invention comprises a protective member which is mounted on the hinge arm. The transmission member passes through the protective member. Thus, the transmission member is prevented from getting into contact with the external environment.
In an embodiment of the present invention, the dishwasher comprises a movement surface which is arranged on the protective member. The transmission member moves by sliding on the movement surface. Thus, the transmission member is supported and guided by the movement surface.
In an embodiment of the present invention, the dishwasher comprises a channel which is provided on the protective member and which enables the transmission member moving on the movement surface to be guided in the vertical plane. The transmission member moving on the movement surface moves in the vertical plane to be connected to the door.
In an embodiment of the present invention, the dishwasher comprises a abutment member which is arranged on the protective member. The abutment member bears against the hinge arm. Thus, the position of the protective member on the hinge arm is determined.
In an embodiment of the present invention, the dishwasher comprises at least one hole which is provided on the protective member and at least one fixing member which engages with the hole. The fixing member passes through the hole and enables the protective member to be fixed to the hinge arm.
In an embodiment of the present invention, the dishwasher comprises the protective member which has a form suitable to be attached onto the hinge arm. Thus, the protective member can be easily attached onto the hinge arm.
By means of the present invention, a dishwasher is realized, comprising a protective member ensuring the safety of the user during the opening and closing of the door.
A dishwasher realized in order to attain the aim of the present invention is illustrated in the attached figures, where:

Figure 1 - is the sideways view of the dishwasher.

The dishwasher (1) comprises a body (2); a washing tub (3) which is provided in the body (2) and wherein the washing process is performed; a door (4) which enables the washing tub (3) to be isolated from the outer environment and which is opened downwards by rotating around the horizontal axis; a decorative panel (D) which is attached onto the door (4); a hinge (5) which enables the door (4) to be connected so as to move on the body (2); a hinge arm (6) which extends from the door (4) towards the lower section of the washing tub (3); at least one pulley (7) which is provided under the hinge arm (6); and a transmission member (9), one end of which extends as connected to the hinge arm (6) and passes over the pulley (7) and the other end of which is connected to a movement member (8) which slidably moves in the horizontal plane.
The dishwasher (1) of the present invention comprises a protective member (10) which is attached to the hinge arm (6) and through which the transmission member (9) passes. The protective member (10) is attached to the hinge arm (6) to enable the transmission member (9) to be isolated from the external environment. Thus, the user is protected from the transmission member (9) which moves during the opening and closing of the door (4).
In an embodiment of the present invention, the dishwasher (1) comprises a movement surface (11) which is arranged on the protective member (10) and whereon the protective member (9) slidably moves. The transmission member (9) moves by sliding on the movement surface (11). By means of the movement surface (11), the transmission member (9) is guided and supported. Thus, the transmission member (9) is prevented from leaving the system or moving in an uncontrolled manner or getting stuck on different surfaces. The system is enabled to operate in a regular and controlled manner.
In an embodiment of the present invention, the dishwasher (1) comprises a channel (12) which is provided on the protective member (10) and which enables the transmission member (9) moving on the movement surface (11) to be guided in the vertical plane. The transmission member (9) moving on the movement surface (11) is guided onto the channel (12). Thus, the transmission member (9) is enabled to be guided in the vertical plane. At this point, the transmission member (9) is connected to the door (4).
In an embodiment of the present invention, the dishwasher (1) comprises an abutment member (13) which is arranged on the protective member (10) and which extends towards the hinge arm (6) so as to enable the protective member (10) to be positioned on the hinge arm (6). The abutment member (13) bears against the side of the hinge arm (6). Thus, the position of the protective member (10) on the hinge arm (6) is determined.
In an embodiment of the present invention, the dishwasher (1) comprises at least one hole (14) which is provided on the protective member (10) and at least one fixing member (15) which engages with the hole (14) so as to enable the protective member (10) to be fixed to the hinge arm (6). After the abutment member (13) is attached to the hinge arm (6), the holes (14) engage with appropriate parts and the protective member (10) is enabled to be attached to the hinge arm (6) by means of the fixing member (15). The protective member (10) is fixed onto the hinge arm (6). When the hinge arm (6) moves, the protective member (10) also moves together with the hinge arm (6).
In an embodiment of the present invention, the dishwasher (1) comprises the protective member (10) which has a matching form with the hinge arm (6). The protective member (10) is formed so as to be easily attached onto the hinge arm (6). The protective member (10) bears against the sides of the hinge arm (6). Thus, ease of production is provided.
By means of the present invention, a dishwasher (1) is realized, comprising a protective member (10) covering the transmission member (9) moving during the opening and closing of the door (4). Thus, the movement member (8) is enabled to be isolated from the external environment. Consequently, the safety of the user is improved. Moreover, the risk of failure of the door (4) opening and closing mechanism is reduced.
