Dishwasher

Abstract

A dishwasher having a washing chamber, a rack, and a pivot arm arrangement supporting the rack relative to the washing chamber. The pivot arm arrangement is movable from a lower position to an upper position so as to elevate the rack from the first extracted position to an elevated position. The dishwasher further comprises an actuator assembly transferrable between a first state in which the actuator assembly is configured to cause the pivot arm arrangement to move from the lower position towards the upper position upon movement of the rack to a first extracted position, and a second state in which the actuator assembly is configured to allow movement of the rack in a horizontal direction out from the washing chamber past the first extracted position.

1 . A dishwasher comprising:
 a washing chamber,   a rack configured to move in a horizontal direction into and out from the washing chamber between an inserted position and a first extracted position,   a pivot arm arrangement supporting the rack relative to the washing chamber, wherein the pivot arm arrangement is movable from a lower position to an upper position so as to elevate the rack from the first extracted position to an elevated position, and   an actuator assembly reconfigurable between:
 a first state in which the actuator assembly is configured to cause the pivot arm arrangement to move from the lower position towards the upper position upon movement of the rack to the first extracted position, and 
 a second state in which the actuator assembly is configured to cause the pivot arm arrangement to remain in the lower position upon movement of the rack to the first extracted position and allow movement of the rack in the horizontal direction out from the washing chamber past the first extracted position. 
   
     
     
         2 . The dishwasher according to  claim 1 , wherein the actuator assembly is biased towards the first state. 
     
     
         3 . The dishwasher according to  claim 1 , wherein the actuator assembly is arranged on the rack. 
     
     
         4 . The dishwasher according to  claim 1 , wherein the actuator assembly comprises an actuator configured to reconfigure the actuator assembly from the first state to the second state. 
     
     
         5 . The dishwasher according to  claim 4 , wherein the rack comprises a handle configured to facilitate movement of the rack in the horizontal direction into and out from the washing chamber, and wherein the actuator is arranged adjacent to the handle. 
     
     
         6 . The dishwasher according to  claim 5 , wherein the actuator is movable between the first and second states, and wherein the actuator assembly is reconfigured from the first state to the second state when the actuator is moved in a direction towards the handle. 
     
     
         7 . The dishwasher according to  claim 4 , wherein the actuator assembly comprises an actuator arm hinged relative to the rack, and wherein the actuator is arranged on the actuator arm. 
     
     
         8 . The dishwasher according to  claim 1 , and wherein the dishwasher comprises a lock assembly configured to, in a locked state, lock the pivot arm arrangement in the lower position, and in an unlocked state, unlock the pivot arm arrangement from the lower position, and wherein the actuator assembly is configured to cause the pivot arm arrangement to move from the lower position towards the upper position by transferring the lock assembly to the unlocked state, and is configured to cause the pivot arm arrangement to remain in the lower position by assuming a state which causes the lock assembly to remain in the locked state. 
     
     
         9 . The dishwasher according to  claim 8 , wherein the lock assembly comprises a locking member and a locking element, the locking member being provided with a first recess, wherein the locked state constitutes a state in which the locking element is positioned in the first recess, and wherein unlocked state constitutes a state in which the locking element is positioned outside of the first recess. 
     
     
         10 . The dishwasher according to  claim 9 , wherein the locking element is arranged on the pivot arm arrangement. 
     
     
         11 . The dishwasher according to  claim 9 , wherein the dishwasher comprises a rail allowing the movement of the rack in the horizontal direction into and out from the washing chamber, and wherein the locking member is configured to be stationary relative to the rail. 
     
     
         12 . The dishwasher according to  claim 9 , wherein the actuator assembly comprises an actuator member arranged to move the locking element out of the first recess when the actuator assembly is in the first state and when the rack is moved to the first extracted position. 
     
     
         13 . The dishwasher according  claim 12 , wherein:
 the actuator assembly comprises an actuator configured to reconfigure the actuator assembly from the first state to the second state;   the actuator assembly comprises an actuator arm hinged relative to the rack, and wherein the actuator is arranged on the actuator arm; and   the actuator member is operably connected to the actuator via the actuator arm.   
     
     
         14 . The dishwasher according to  claim 12 , wherein the actuator assembly is arranged to, upon transfer to the second state, move the actuator member to a position which causes the locking element to remain in the first recess upon movement of the rack to the first extracted position. 
     
     
         15 . The dishwasher according to  claim 12 , wherein the locking element is arranged to abut against the actuator member to hinder a horizontal movement of the rack past the first extracted position when the actuator assembly is in the first state. 
     
     
         16 . The dishwasher according to  claim 12 , wherein the actuator member is configured to assume a position which allows movement of the actuator member past the locking element in the horizontal direction out from the washing chamber when the actuator assembly is in the second state. 
     
     
         17 . The dishwasher according to  claim 8 , wherein the lock assembly is transferrable to an upper locked state in which the lock assembly locks the pivot arm arrangement in the upper position, and wherein the actuator assembly is operably connected to the lock assembly for unlocking the lock assembly from the upper locked state.
