Description

Technical Field

[0001] The invention relates to the field of dishwashers, in particular to a dishwasher rack, more particularly to an adjustable lifting dishwasher rack structure, and also to a dishwasher equipped with the rack. Background Art

[0002] As people's living standards improve, dishwashers have gradually entered ordinary households and become a common household appliance. When in use, at least one shelf needs to be placed in the inner tank of the dishwasher, and the user places tableware items such as cups, plates, and bowls to be washed on the shelf, and the items to be washed placed on the shelf are washed by a spray device arranged in the inner tank of the dishwasher.

[0003] In order to place more items to be washed and make full use of the space in the dishwasher, the dishwasher in the prior art usually has two layers of shelves, each of which is designed with some special-shaped areas to accommodate items of various shapes to be washed.

[0004] However, the arrangement of the upper and lower shelves will leave a gap between the two shelves, and other dishes can no longer be placed and washed in the gap; at the same time, the fixed shape of the two shelves limits the need to wash some special-shaped dishes, so it still cannot maximize the use of the space in the dishwasher.

[0005] In order to solve the above problems, some dishwashers on the market are equipped with a third rack. If a third rack is simply placed on the upper rack, the distance between the upper rack and the third rack may be smaller than the laundry on the upper rack. A further solution is to set a plastic rack inside the third rack to achieve mobility, but it can only meet the customer's specific tableware placement. Currently, dishwashers with a third rack are basically fixed wire frames, and the number and size of tableware accommodated are also fixed. Some dishwashers have a third rack that can achieve lifting or reversing functions, most of which are assisted by a plastic frame or a reversing mechanism. The existing solutions have many rack parts, complex structures, high costs, and more plastic mechanisms, resulting in poor overall drying effect of the dishwasher.

[0006] In addition, the existing dishwasher racks are generally fixed structures with iron wires forming a grid shape, and the frame body has a fixed outline, on which some reversible brackets are installed to adapt to tableware of different sizes and shapes. Although this can facilitate the placement of tableware of different specifications, due to the fixed outline of the rack, especially the inability to adjust the depth, the fixed-size rack cannot be adjusted in depth to adapt to the washing of various types of tableware.

[0007] In view of this, the present invention is proposed. Summary of the invention
