A pivoting and lifting structure with push-pull locking, a dishwasher, and a household appliance are disclosed. To move the storage portion from an initial position to a position convenient for the user, the storage portion is first pulled out from the initial position. Then, the storage portion continues to be pulled to drive the swing portion to rotate to lift the storage portion. At this time, the guide portion is located at an inlet of a guide groove, enabling the guide portion to slide or roll along the guide groove. Therefore, the storage portion will not shake at the front and rear positions when it pivots upwards. Finally, the storage portion is pushed or pulled and the guide portion slides into the limiting groove to be in the locking position, preventing the guide portion returning in the direction opposite to the extension direction of the guide groove.

A dishwasher rack for a dish washing appliance. The dishwasher rack may be positionable between a variety of height positions. A drive mechanism may assist the dishwasher rack between the vertical positions. A worm screw may be coupled to a motor and may be positioned within the dishwasher tub.

Provided is an appliance lift assembly, comprising a surface base, a support frame, a platform configured to support an appliance unit, such as a dishwasher, the platform being movable in relation to the support frame, and a lifting system mounted to the movable platform and mounted to the support frame, the lifting system moving the platform between an extended mode and a retracted mode, wherein the appliance lift assembly fit into standard built-in cabinet enclosure. Further provided is a method for elevating or lowering an appliance unit using a lifting system, the method comprising pulling a cable attached to a platform of the lift assembly supporting the appliance, lifting the movable platform by using a rotational or linear motion drive and by using a passive lifter, and stopping movement of the platform when a predetermined height is reached. A method for installing an appliance lift assembly is also provided.

A sliding-pivoting mechanism of a shelf includes a first pivot arm and a second pivot arm. The pivot arms are attached to side walls of a body and arranged parallel to each other at a distance from each other. A guide rail is fastened to second ends of the pivot arms in such a way that the guide rail can be pivoted parallel to the plane of the side walls and that the guide rail can be pivoted from a lower position to a raised, upper position. The mechanism also includes at least one running rail, which can be moved linearly in the guide rail and to which the shelf is fastened. The sliding-pivoting mechanism includes a locking mechanism for preventing a pivoting motion of the sliding-pivoting mechanism in a raised and a lowered end position. The locking mechanism is arranged on the guide rail and on one of the pivot arms and can be actuated by means of an activator fastened to the running rail.

The inconvenience associated with using a lower basket of a dish washing machine is reduced or eliminated by a dish washing machine which includes a washing tub with an open front, a basket configured to be inserted in or drawn out from the washing tub through the open front of the washing tub, a door which opens or closes the open front of the washing tub, at least one guide rail for mounting the basket on the door when the basket is drawn out from the washing tub while the door is open, and a lifting device which guides the guide rail to move between a raised position and a lowered position of the guide rail.

A dishwasher, including a chamber for washing dishes and a chamber for storing dishes is provided. A mechanism is also provided allowing the dish racks to move the dishes from the washing chamber to the storage chamber of the dishwasher once the wash is completed.

A rack lifting assembly for a dishwasher appliance is provided. The rack lifting assembly includes frame having rotatably mounted wheels to enable the frame to be rolled in and out of the wash chamber of the dishwasher appliance. A lower rack may be operably coupled to the frame by a pulley system including a rope winding between a first set of pulleys mounted to the frame and a second set of pulleys mounted to the lower rack. A retracting means, such as a motor, may wind and unwind a rope of the pulley system to move the lower rack vertically within the frame. Linear slides are mounted on the left and right sides of the frame to guide the lower rack, thereby keeping it in a horizontal orientation while lifting.

A lower rack assembly for a dishwasher appliance includes a lower rack configured for receipt of articles for washing, and a lift assembly connected to the lower rack. The lift assembly includes a first arm extending between a first end and a second end, the first end of the first arm pivotally coupled to the lower rack, and a first bracket defining a first slot, the second end of the first arm movably coupled to the first slot. Movement of the lower rack along the vertical direction causes movement of the second end of the first arm relative to the first slot along the transverse direction and pivotal rotation of the first end of the first arm.

A sliding-pivoting mechanism of a shelf includes a first pivot arm and a second pivot arm. The pivot arms are arranged attached to sidewalls of a body and parallel to each other at a distance from each other. A guide rail is fastened to second ends of the pivot arms in such a way that the guide rail can be pivoted parallel to the plane of the side walls and that the guide rail can be pivoted from a lower position space to a raised, upper position. The mechanism also includes at least one running rail, which can be moved linearly in the guide rail and to which the shelf is fastened. The sliding-pivoting mechanism includes a locking mechanism for preventing a pivoting motion of the sliding-pivoting mechanism in a raised and a lowered end position. The locking mechanism is arranged on the guide rail and on one of the pivot arms and can be actuated by means of an activator fastened to the running rail.
