Dishwasher zone wash controllable spray device

Abstract

The invention is applied to the field of dish-washing machines, and discloses a controllable regional washing jetting device of a dish-washing machine. The controllable regional washing jetting device comprises a water conveying pipe component, a plurality of branch pipes mounted on the water conveying pipe component, a plurality of spraying heads respectively mounted on the branch pipes, a plurality of elastic supporting components which are mounted on the water conveying pipe component and are respectively arranged beside all the branch pipes and a plurality of switch control components respectively mounted on the corresponding elastic supporting components, wherein all the branch pipes are provided with hollow inner holes and side opening holes communicated with the hollow inner holes; one ends of all the switch control components are respectively connected with the elastic supporting components in a fastening manner, and the other ends of the switch control components are respectively inserted into the side opening holes in a telescopic manner. According to the controllable regional washing jetting device of the dish-washing machine, the switch control components are used for controlling opening and closing of the branch pipes, so that the branch pipes can be blocked in a closed state when no specific tableware is placed in a specific region corresponding to the controllable regional washing jetting device, and the spraying heads cannot spray water outwards; therefore, waste of water resources is avoided, and loss of water pressure of a water supply system is avoided.

Description

technical field [0001] The invention belongs to the field of dishwashers, in particular to a controllable jetting device for area washing of dishwashers. Background technique [0002] The dishwasher generally includes a main spray arm device and an area washing spray device, wherein the main spray arm device is used to wash the tableware placed in the washing cavity on a large scale, and the area wash spray device is mainly used to wash the tableware placed in a specific area. Rinse the specific tableware (such as cups, etc.) inside. Although the existing area washing spray device can also realize the flushing of specific tableware in a specific area, it still has deficiencies in specific applications. Place specific tableware, as long as the dishwasher starts to run, the area washing spray device will spray washing water outwards, because the washing water sprayed by the area washing spray device at this time does not play the role of effectively rinsing the specific table...
