    Description


    [0001] The present invention relates to a dishwasher comprising an automatic door opening mechanism.

    [0002] In dishwashers, the drying process is performed after the washing process. In some embodiments, upon the completion of the washing and drying processes, the door of the dishwasher can be partially opened automatically, the hot vapor therein is discharged to the outer environment and the washed items are enabled to dry faster. In dishwashers wherein the door is partially opened automatically at the end of the washing and drying processes, applying lower temperatures in the drying process is sufficient and thus, energy is saved. Opening of the dishwasher door automatically, furthermore, prevents the vapor getting cold from condensing and leaving stains on the washed items. In the state of the art, in order for the door to open automatically, door opening mechanisms are used, which extend from the body towards the door and enable the door to be partially opened by pushing the door with the activation of devices such as solenoid or electric motor. However, in order to effectively discharge the steam in the dishwasher, only the opening of the door is not sufficient, and a certain gap must remain between the door and the body to enable discharging of the steam outside.

    [0003] In the state of the art European Patent No. EP1909631, a spring which balances the weight of the door by applying a force on the door of the dishwasher and an adjustment mechanism which adjusts the tension of the spring are disclosed.

    [0004] In the state of the art United States Patent No. US2010225211, a door is configured to pivot at a bottom section of a dishwasher around a horizontally running axis and a control device switches the illuminating device on or off based on an opening position of the door.

    [0005] In the state of the art China Patent No. CN104688159, an automatic door opening function of a dishwasher is disclosed.

    [0006] In the state of the art German Patent No. DE102012211254, a household dishwasher, with a locking arrangement and a door weight compensation system is disclosed.

    [0007] In the state of the art United States Patent No. US2016029873, a balancing system of the door of a household appliance is disclosed.

    [0008] In the state of the art United States Patent No. US2011074261, a latch keeper disposed on the washing tub and mounted on a push rod, and a pivotable door configured to close the washing tub of the dishwasher is disclosed.

    [0009] The aim of the present invention is the realization of a dishwasher comprising a door opening mechanism which enable the door to be partially opened automatically.

    [0010] The dishwasher realized in order to attain the aim of the present invention, explicated in the first independent claim and the respective dependent 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 locking mechanism which enables the door to be locked on the body; a control unit which enables the door to be opened partially upon the completion of the washing and drying processes; a hinge which enables the door to be connected to the body; and a hinge arm connected to the hinge. The kitchen utensils 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. By means of the locking mechanism provided on the door, the door is fixed onto the body. By opening the door partially upon the completion of the main washing and drying steps, the humidity in the washing tub is enabled to be discharged. Thus, the drying process is performed more effectively. Furthermore, energy saving is provided. Upon the completion of the main washing and drying steps, the locking mechanism is triggered by means of the control unit such that the door is enabled to be opened partially. 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.

    [0011] The dishwasher of the present invention comprises the locking mechanism having at least one spool provided under the hinge arm, a first spring provided under the washing tub, a movement member which extends along the first spring, a stopper provided on the body and against which one end of the movement member bears and a transmission member which is connected to the hinge arm at one end and to the movement member at the other end. The transmission member extends from the hinge arm towards the spools. The transmission member which changes direction while passing the spools is connected to the movement member on the horizontal plane. The movement member moves in the first spring when the door is opened/closed. Thus, the transmission member exerts force onto the hinge arm.

    [0012] According to the present invention, the dishwasher comprises the cylindrical first channel, a second channel having a smaller diameter than that of the first channel, and an abutment arranged between the first channel and the second channel where the diameter changes. The first channel and the second channel are in the form of hollow cylinders. The end of the second channel which is not connected to the first channel may be conical. The transmission member is connected to the movement member via the first channel and the second channel.

    [0013] According to the present invention, the dishwasher comprises a compression member which presses the transmission member and enables the same to be moved. The transmission member moves between the first channel and the second channel.

    [0014] In an embodiment of the present invention, the dishwasher comprises the conical compression member in the form of a cone. While the wider section of the compression member is on the first channel, the narrower section thereof moves on the second channel.

    [0015] According to the present invention, the dishwasher comprises a protrusion which is provided on the compression member. As the compression member moves towards the second channel, the protrusion contacts the abutment and stops at a predetermined position. Thus, the transmission member is prevented from being released from the movement member.

    [0016] According to the present invention, the dishwasher comprises the door which has a closed position, a partially open position and an open position. When the door is in the closed position, the protrusion is on the first channel. When the door is in the partially open position, the protrusion contacts the abutment. When the door is in the open position, the contact between the movement member and the stopper is interrupted, and the protrusion is removed from over the abutment so as to enable the movement member to move in the horizontal plane.

    [0017] In an embodiment of the present invention, the dishwasher comprises the first spring which is provided along the outer surface of the movement member and a second spring which is provided along the inner surface of the second channel. By means of the first spring, the movement moves in the horizontal plane and returns to its initial position. By means of the second spring, the compression member is enabled to move in the second channel and return to its initial position.

    [0018] In an embodiment of the present invention, the dishwasher comprises the second spring which is stretched when the door is in the closed position and the first spring which is stretched when the door is in the open position. When the door is in the closed position, the second spring is stretched and the first spring is at rest, when the door is in the partially open position, the first spring and the second spring are at rest and when the door is in the open position, the first spring is stretched and the second spring is at rest.

    [0019] In an embodiment of the present invention, the dishwasher comprises a tensioning member which enables the excess part of the transmission member to be wound. Thus, the transmission member is prevented from being released from the spools as the door changes position.

    [0020] In an embodiment of the present invention, the dishwasher comprises the tensioning member which is in the form of a spring.

    [0021] By means of the present invention, a dishwasher is realized, comprising a movement mechanism which enables the door to be opened and kept in the desired position upon the completion of the washing and drying processes. Thus, the drying effectiveness is improved and ease of use is provided.
