Abstract
The invention relates to a suspension spray arm structure for an uncovering-type dish washing machine. The structure comprises a spray arm, wherein the spray arm is internally provided with a water supply cavity and the upper surface of the spray arm is provided with water-spraying holes communicated with the internal water supply cavity, the spray arm is arranged on a center shaft by virtue of a water distribution sleeve at the center, the inner diameter of the water distribution sheath is slightly more than the outer diameter of the center shaft, wherein the outer diameter of the center shaft is 2-6mm, the lower end of the water distribution sleeve and the upper end of a water supply sleeve are in a separation structure, and the water distribution sleeve is supported on the water supply sleeve. When the suspension spray arm structure is in operation and high pressure water generated by a water pump enters into the water supply cavity from the water supply sleeve by virtue of the water distribution sleeve, a part of water flow can flow out downward from the lower side of the water distribution sleeve, the spray arm can be pushed to float upward by a reverse upward acting force generated by the spray arm, another part of water flow can flow out from a gap between the water distribution sleeve and the center shaft to form a water film layer, and lubrication is produced by the water film layer in a rotating process. The frictional force of the spray arm structure provided by the invention is greatly reduced, the center shaft is difficult to wear, and the rotating speed of the spray arm is fast.
Description
(1) technical field:
The present invention relates to the floated spray arm structure of a kind of covering type use in dishwasher, relate to the dish-washing machine technical field.
(2) background technology:
The covering type dish-washing machine by lower house, be installed in the lower house upper end cover of going up that carrying handle is installed to be opened/closed, be installed in the inner floated spray arm of cover and bowl basket, grid, be installed in boiler, clear water tanks and water pump and electric appliance box composition thereof in the lower house.Floated spray arm is installed on the center bar, is hollow structure, has hole for water spraying on it, and the inner inner chamber of floated spray arm is connected by water supply sleeve pipe and heat-exchanger pump outlet, and the opening direction of hole for water spraying is towards the bowl basket.During work, heat-exchanger pump is extracted the hot water in the water tank out, sends into the spray arm of hollow through the water supply sleeve pipe, and sprays from hole for water spraying under certain pressure, forms intensive flow of hot water; Be ejected on the tableware in bowl basket, tableware is carried out jet douche and drenches brush, reach the purpose of cleaning tableware.In this process, spray arm can make spray angle constantly change owing to the reaction of being sprayed water is rotated, and to guarantee to wash in all directions tableware, last water still falls into boiler.
In the prior art, spray arm inside has the water supply cavity, the spray arm upper surface has the hole for water spraying that interlinks with the private water supply cavity, this water supply cavity interlinks with the water supply sleeve pipe that is connected supply-water pump, spray arm is installed on the central shaft by the installed part at its center, water supply cavity and water supply cannula cavity junction are enclosed construction, there is following shortcoming in it: 1, fit clearance is about 0.1mm between installed part and central shaft, between spray arm when rotation and central shaft is contact mechanical friction, central shaft is easy to wear, 2, between installed part and its water supply sleeve pipe of supporting is contact mechanical friction, frictional force is big, and the spray arm rotating speed is slow, and rotation efficiency is low.Need be improved.
(3) summary of the invention:
The present invention aims to provide the floated spray arm structure of covering type use in dishwasher that a kind of central shaft is not easy to wear, the spray arm rotating speed is fast.
Technical solution of the present invention is as follows:
The floated spray arm structure of a kind of covering type use in dishwasher, the spray arm of the hole for water spraying that comprises that inside has the water supply cavity, upper surface has and interlink with the private water supply cavity, above-mentioned water supply cavity interlinks with the water supply sleeve pipe that is connected supply-water pump, described spray arm is installed on the central shaft by the installed part at its center, it is characterized in that: described installed part is a branch water jacket, its internal diameter divides gap and water supply cannula cavity between water jacket and central shaft to interlink greater than the external diameter 2-6mm of central shaft.
Said structure has determined the water supply sleeve pipe when supplying water, and the part current will flow out from the gap location between minute water jacket and central shaft.
Further technical scheme is:
There is the opening under the direction side direction lower end of described minute water jacket, divides the upper end of water jacket and water supply sleeve pipe to be isolating construction, divides water jacket to be supported on the water supply sleeve pipe.
Said structure has determined the water supply sleeve pipe when supplying water, and the part current will flow out from the opening part under the direction side direction of minute water jacket lower end.
When the present invention worked, when the water under high pressure that produces when water pump entered the water supply cavity by the water supply sleeve pipe by a minute water jacket, current had three directions, and the one, enter the water supply cavity and through the hole for water spraying ejection, spray arm can be owing to the reaction of being sprayed water is rotated; The 2nd, owing to divide water jacket to be supported on the water supply sleeve pipe, the part current can outwards be flowed out by the downside of minute water jacket, spray arm can promote upwards to float owing to the reverse upwards active force of its generation, promptly, be faint suspended state during the spray arm rotation, it and water supply sleeve pipe form water film between the upper end, are produced lubricated in rotary course by water film; The 3rd, the part current flow out in the gap by minute water jacket and central shaft, and during the spray arm rotation, the gap of 2-6mm has guaranteed to form water film between branch water jacket and the central shaft, are produced lubricated in rotary course by water film.Because adopt technique scheme, frictional force declines to a great extent, central shaft is not easy to wear, the spray arm rotating speed is fast.Realized goal of the invention easily.
Above-mentioned 2-6mm has taken into full account and has reduced friction and by the overflow between minute water jacket and central shaft the loss of washing pressure is influenced problem, and the hydraulic pressure that reduces thus in this scope can be ignored with respect to the high pressure high flow capacity of water pump.
(4) description of drawings:
Below with reference to drawings and Examples the present invention is described in further details:
Accompanying drawing 1 is the structural representation of the embodiment of the invention.
Each sequence number is respectively in the accompanying drawing 1: 1, central shaft; 2, jump ring; 3, pad; 4, spray arm; 5, divide water jacket; 6, water supply cavity; 7, hole for water spraying; 8, water supply sleeve pipe; I, High-Pressure Water; The overflow that forms between II, the downside that divides water jacket and the water supply sleeve pipe upper end; The overflow of the formation between III, branch water jacket and central shaft; IV, the working flow that enters the water supply cavity and spray through hole for water spraying.
