Spray arm unit for baby warewashing machines

Abstract

The invention relates to a spraying arm device of a baby ware washing machine. The spraying arm device comprises a spraying arm upper piece and a spraying arm lower piece which are each provided with a half pipe wall. The half pipe wall of the spraying arm upper piece and the half pipe wall of the spraying arm lower piece are folded together to form a water channel after the spraying arm upper piece and the spraying arm lower piece are connected. The spraying arm upper piece is provided with a plurality of water spraying openings which are communicated with the water channel. A water inlet is formed in the spraying arm lower piece and communicated with the water channel. Water blocking protrusions are arranged on the inner surface of the half pipe wall of the spraying arm lower piece and located below the water spraying openings. Vortex grooves are formed in the peripheries of the water blocking protrusions. One part of water rebounds out of the water spraying openings after hitting the highest points of the water blocking protrusions, the other part of water rebounds out of the water spraying openings after hitting the water blocking protrusions and flowing into the vortex grooves, water is sprayed out of the water spraying openings in a dispersed mode, the water spraying openings are formed in bosses of different angles and heights, finally water sprayed out of the water spraying openings are sprayed out in a dispersed mode at different angles and different heights to wash baby ware, and the aims of saving water and being efficient in washing are achieved.

Description

technical field [0001] The invention relates to the field of baby utensil washing machines, in particular to a spray arm device of the baby utensil washing machine. Background technique [0002] The currently known cleaning device for baby utensils consists of a cleaning tank and an ultrasonic generator. The baby utensils are placed in the cleaning tank. It cannot be drained away, there is precipitation, and the water consumption is large, and functions such as drying cannot be performed. [0003] At present, there are two kinds of known baby utensil disinfection devices, one is heated by water tank and utilizes steam for disinfection, but it cannot be dried. The other is similar to the drying principle of the disinfection cabinet, but it cannot perform the cleaning function. [0004] At present, there is an integrated baby utensil washing machine that can clean, sterilize, and dry baby utensils. The baby utensils are rinsed and cleaned in the second cycle, and the genera...

Problems solved by technology

But this machine still has the following disadvantages: the spray arm device of this machine adopts a more traditional method, and multiple water nozzles are set on the plate, the inner cavity of the plate is hollowed out to form a water channel, and the bottom of the plate is provided with a water inlet, and the water enters along the edge of the plate. The water port enters the water channel in the inner cavity of the plate, and then the water flows out through the water nozzle to rinse the baby utensils. Although this method can clean the baby utensils, the cleaning angle is not comprehensive, the cleaning efficiency is low, and the water consumption is low. Large, requires multiple flushes to get baby utensils clean
