Dish-washing machine spraying device, spraying method and dish-washing machine

Abstract

The invention relates to a dish-washing machine spraying device, a spraying method and a dish-washing machine. A stream guidance device, which can do axial rotation relative to a spraying nozzle, is arranged at the front side of a spraying hole of the spraying nozzle; the stream guidance device can become rotating through a water flow which is sprayed out from the spraying hole; and meanwhile, washing water, under centrifugal force which is generated from the rotating stream guidance device, is sprayed out in a diverging form. The spraying device provided by the invention is beneficial for flushing and washing tableware in the dish-washing machine in a certain direction, so that the occurrence of a washing dead angle can be effectively prevented; moreover, the spraying device is beneficialfor cleaning the tableware in various shapes; and in addition, the stream guidance device, which can only rotate around own axis, can only occupy own space, so that the occupied space of the sprayingdevice is greatly diminished.

Description

Technical field [0001] The invention relates to a dishwasher, and at the same time relates to a dishwasher spray device and a spray method installed in the dishwasher, and belongs to the technical field of dishwasher manufacturing. Background technique [0002] Dishwasher is a device that uses nozzles to spray high-pressure washing water to clean tableware. Dishwashers generally include a dishwasher liner that forms a washing chamber. The front of the liner has a tableware inlet, and a door is provided at the tableware inlet , There are tableware shelves and showers in the washing room. [0003] In order to improve the washing effect, the sprayer installed in the dishwasher generally uses a rotatable sprayer. The sprayer consists of a spray arm and multiple nozzles installed on the spray arm. The spray arm Connected to the motor and driven by the motor to rotate 360 ​​degrees in the horizontal plane, the water jet will form a circular shape while spraying upward, so as to realize ...

AI Technical Summary

Problems solved by technology

[0004] But in the rotary shower in the prior art, the sprayed water column is a circle on the horizontal plane. For strip-shaped tableware, if you want to achieve comprehensive washing, you have to increase the diameter of the spray arm, or you must increase the diameter of the spray arm. The high water pressure will cause a large amount of water to be sprayed in the place where there is no tableware in the dishwasher, resulting in waste of water

Since the shower is generally installed below the dishwasher, the sprayed water column is easily blocked by the shelf above, resulting in unsatisfactory local washing effect. In addition, a sprinkler is installed, which not only makes the structure of the dishwasher more complicated, but also increases the water consumption, resulting in a large amount of water waste.

In addition, in order to realize the rotation of the spray arm, there must be a gap between the sprayer seat and the sprayer seat, which will cause leakage, and to ensure the smooth rotation of the spray arm in the horizontal plane, it needs to occupy a large internal space of the dishwasher
