Disclosed herein are a nozzle assembly for a dishwasher capable of evenly spraying wash water in a wash tub and a dishwasher having the same. The dishwasher includes a sump to pump wash water, a supply pipe to which the wash water from the sump is supplied, and a nozzle assembly connected to the supply pipe. The nozzle assembly includes a lower rotor arm connected to the supply pipe, an upper rotor arm having a portion rotatably received in the lower rotor arm and having a first rotation center of an upper end thereof and a second rotation center of a lower end thereof positioned eccentrically from the first rotation center, and a nozzle rotatably connected to the upper rotor arm.

The invention discloses a gushing arm assembly for a bowl washing machine and a bowl washing machine with the gushing arm assembly. The gushing arm assembly comprises a fixed gear, a main gushing arm, at least one movable gushing arm and a transmission gear, wherein the fixed gear is a non-round gear; the main gushing arm is arranged on the fixed gear around the axial line of the fixed gear in a rotatable manner; a first spraying opening is formed in the main gushing arm; the movable gushing arms are movably arranged on the main gushing arm in the directions close to and far away from the axial line of the fixed gear; a second spraying opening is formed in each movable gushing arm; and the transmission gear is connected with the movable gushing arms in a rotatable manner, is meshed with the fixed gear, and is used for driving the movable gushing arms to move during rotation of the main gushing arm. According to the gushing arm assembly for the bowl washing machine, telescopic moving traces of the movable gushing arms can be formed under the meshing transmission of the transmission gear and the fixed gear, so that the flushing area of the gushing arm assembly is enlarged, and the cleaning effect is enhanced.

A dishwasher having a spray unit fixed at a washing tub and configured to spray wash water, and a conversion assembly provided as to convert the direction of the wash water being sprayed from the spray unit toward a tableware basket. The conversion assembly includes a vane rotatably provided while disposed as to face with respect to the spray unit such that the direction of the converted wash water is adjusted. Through the structure as such, the spraying range of the wash water is extended, and may be able to minimize noise from the striking of the wash water against an inside wall or door of the dishwasher.

The invention provides a large-caliber quartz tube cleaning method, which comprises the following steps that firstly, quartz tubes are placed into an acid washing groove with the hydrofluoric acid concentration being 15 percent to 20 percent to be soaked for 10 to 15 minutes; then, the quartz tubes are placed into an acid washing groove with the hydrofluoric acid concentration being 7 percent to 10 percent to be soaked for 15 to 20 minutes; then, the quartz tubes are placed into a tap water groove to be soaked for 4 to 6 minutes; next, the quartz tubes are placed into a deionized water groove to be soaked for 4 to 6 minutes; the soaked quartz tubes are placed into a cleaning machine to be flushed for 18 to 25 minutes, and the cleaning is completed. The large-caliber quartz tube cleaning method has the advantages that the step-by-step cleaning is carried out on the quartz tubes, so impurities on the quartz tube walls can be thoroughly soaked; through the arrangement of a horizontal slide passage and a slide block, the reciprocating flushing can be realized, and the flushing range is wide; an upper spray head and a lateral spray head are adopted, cleaning dead corners do not exist, and the overall cleaning of the quartz tubes is ensured; a multi-way connecting head is arranged, the cleaning on several groups of quartz tubes in one step can be realized, and the cleaning efficiency is improved; the water consumption of a device is low, the water resources are saved, and good cleaning effects are also obtained.
