Description

Technical Field

[0001] This invention belongs to the field of dishwasher technology, specifically, it relates to a sprayer water-guiding mechanism, and also includes a dishwasher equipped with the sprayer water-guiding mechanism. Background Technology

[0002] Dishwashers on the market come in many sizes and specifications based on factors such as the number of place settings and installation methods. The height at which dishes can be placed also varies among different sizes of dishwashers, which also restricts the space inside the drum. In order to make reasonable use of the internal space of the racks and meet the washing requirements of dishes of different heights, and to adjust the installation height of the sprayer, an adjustment structure needs to be installed between the sprayer and the water inlet pipe of the dishwasher to achieve the adjustment of the sprayer installation height.

[0003] Current dishwashers typically only have two or three adjustable upper shelves. While this meets the needs of some users, the increasing size of plates and dishes makes multi-position adjustable upper shelves increasingly important. When the upper shelf position changes, the components of the water inlet pipe assembly also need to be adjusted accordingly. In existing three-position adjustable water inlet pipe assemblies, the water inlets on the water inlet caps are arranged in a straight line. This straight-line arrangement leaves no room for adding another water inlet, thus limiting the upper shelf position adjustment to three positions.

[0004] In view of this, the present invention is proposed. Summary of the Invention
