    Abstract

    The present invention relates to a dishwasher, comprising a rack wherein the dishes are placed; a body that is disposed at both sides of the rack ; a carrier on which the body is mounted, and an arm that is disposed on the body, that has a lock opening position that enables the body to be moved on the carrier when moved towards the rack by applying force and that has a locking position that enables the rack to be kept at the desired height by the position of the body being fixed on the carrier in the situation when the external force is not applied.

    Claims

    1. A dishwasher, comprising a rack wherein the dishes are placed; a body that is disposed at both sides of the rack; a carrier on which the body is mounted, and an arm that is disposed on the body, that has a lock opening position that enables the body to be moved on the carrier when moved towards the rack by applying force and that has a locking position that enables the rack to be kept at the desired height by the position of the body being fixed on the carrier in the situation when the external force is not applied, characterized by a housing arranged on the carrier; more than one recess that is arranged on the body so as to be on top of each other, and a pin that can be moved with the arm by contacting the arm, that is almost entirely outside the housing so as to be seated in the recess when the arm is in the locking position and that is released from the recess by being pushed into the housing by the arm while the arm is brought to the lock opening position.

    [0039] The dishwasher (1) comprises a rack (2) wherein the dishes are placed; a body (3) that is disposed at both sides of the rack (2); a carrier (4) on which the body is mounted, and an arm (5) that is disposed on the body (3), that has a lock opening position that enables the body (3) to be moved on the carrier (4) when moved towards the rack (2) by applying force and that has a locking position that enables the rack (2) to be kept at the desired height by the position of the body (3) being fixed on the carrier (4) in the situation when the external force is not applied. When the arm (5) is brought to the lock opening position, the rack (2) can be moved to the higher or the lower position in the tub by means of the body (3) being slid on the carrier (4). When the arm (5) is set free, the rack (2) is fixed at the present height.

    [0040] The dishwasher (1) of the present invention comprises a housing (6) disposed on the carrier (4); more than one recess (8) that is disposed on the body (3) so as to be on top of each other, and a pin (7) that can be moved with the arm (5) by contacting the arm (5), that is almost entirely outside the housing (6) so as to be seated in the recess (8) when the arm (5) is in the locking position and that is released from the recess (8) by being pushed into the housing (6) by the arm (5) while the arm (5) is brought to the lock opening position. The arm (5) extends downwards between the body (3) and the carrier (4), and is mounted on the body (3) so as to be moved by being rotated around a horizontal rotating axis. When the rack (2) is desired to be carried to the higher or the lower position from the fixed position, the user presses the arms (5) that are disposed at both sides of the rack (2) towards the rack (2) from one end. The pin (7) bearing against the other end of the arm (5) is pushed into the housing (6) by the arm (5) so as to move away from the body (3) and is released from the recess (8). Thus, the rack (2) can be moved by being slid on the carrier (4). When the arm (5) is released as the rack (2) is brought to the desired height level, the force applied by the arm (5) on the pin (7) is removed. Thus, the pin (7) moves outside the housing (6) by returning to the free position, and enables the height of the rack (2) in the cabin to be fixed by being seated in the recess (8) of the present height level of the rack (2).

    [0041] In another embodiment of the present invention, a channel (10) is arranged on the arm (5), through which the end of the pin (7) passes and extends towards the body (3), and the extensions (9) that enable the pin (7) to bear against the arm (5) by contacting the edges of the arm (5) that surround the channel (10) and to move with the arm (5) extend outwards from above the pin (7). When the arm (5) is in the locking position, the end of the pin (7) is seated in the recess (8) by passing through the channel (10) so that the extensions (9) on the pin (7) bear against the arm (5). While the arm (5) is brought to the lock opening position, the protrusions bearing against the arm (5) enable the pin (7) to be pushed into the housing (6) by the arm (5). By means of the channel (10), the movement of the pin (7) is limited.

    [0042] In another embodiment of the present invention, the dishwasher (1) has a first spring (11) that pushes the pin (7) outside the housing (6) when the arm (5) is in the locking position and that enables the pin (7) to be pushed into the housing (6) by being compressed while the arm (5) is brought to the lock opening position. As a result of the pressure exerted to the pin (7) by the arm (5) while the arm (5) is being moved by the user, the first spring (11) is compressed and enables pin (7) to move into the housing (6). When the arm (5) is brought to the locking position by being released, the first spring (11) that is at least partially returned to the balance position pushes the pin (7) outside the housing (6).

    [0043] In another embodiment of the present invention, a ramp (14) that has the shape of an inclined surface towards the recess (8) and that enables the pin (7) to gradually move into the recess (8) while the rack (2) is carried to a relatively higher position than the present position is disposed right under the recess (8). While the rack (2) is carried to a relatively higher position, the end of the pin (7) rubs against the ramp (14), and thus the movement of the pin (7) into the recess (8) is slowed down.

    [0044] In another embodiment of the present invention, a curve that is suitable with the shape of the pin (7) is present at the upper portion of the recess (8). When the arm (5) is in the locking position, the pin (7) is seated in the recess (8) so as to bear against the curved upper wall of the recess (8). Thus, the rack (2) is enabled to be kept steady by preventing the movement of the pin (7) in the housing (6) such as sliding and vibrating.

    [0045] In another embodiment of the present invention, a distance in the horizontal plane remains between the recesses (8) so that the ports of the recesses (8) move closer to the carrier (4) from the top to the bottom. By means of the recesses (8) being positioned in the horizontal direction in a sliding manner with respect to each other, the pin (7) can be leaped over the recesses (8) that are disposed in different distances to the rotating axis of the pin (7) by the arm (5) being rotated in the same angle. Thus, the height of the rack (2) is adjusted, and applying a different amount of force to the arm (5) for each height level is not needed.

    [0046] In another embodiment of the present invention, the dishwasher (1) comprises a pressing plate (12) that extends outwards from the body (3) at one end of the arm (5) and that enables the user to easily move the arm (5). Thus, the area that the force is applied is moved away from the shaft, and the users can move the arm (5) by spending less force.

    [0047] In another embodiment of the present invention, a second spring (13) that supports the pressing plate (12) from the back by being compressed while the arm (5) is brought to the lock opening position is disposed between the body (3) and the pressing plate (12). By means of the second spring (13) that pushes the pressing plate (12) outwards from the rack (2), the pin (7) can be leaped over the recesses (8) in a controlled manner. Thus, the pin (7) can be seated in the next lower recess (8) by being barely leaped over the recess (8), and the rack (2) is prevented from falling to the lowermost level each time.

    [0048] In the dishwasher (1) of the present invention, the pin (7) can linearly move in the horizontal direction by means of the structure of the pin (7) that is independent from the arm (5), and thus the pin (7) is prevented from being released of the recess (8) in cases such as trying to carry the rack (2) by force, or overloading of the rack (2). Moreover, in the dishwasher (1) of the present invention, in cases the rack (2) is lifted up fast, the pin (7) is prevented from leaping several levels, and the perception of quality is increased by enabling the mechanism to operate in a more stable and balanced manner.
