Description
Technical field
The present invention relates to a kind of water pump vanes for cleaning machine, especially a kind of to be used for the cleaning machines such as dishes, fruits and vegetables
In to improve the water pump vane of cleaning effect.
Background technique
For water pump before work, water pump and water inlet pipe must fill water, rely on high-speed rotating impeller later, make liquid used
Property centrifugal force under the action of obtain energy so as to improve pressure in it, when impeller quickly rotates, the first blade promotes water quickly
Rotation, as the effect of centrifugal force flies out from impeller, after the water in water pump is spilled over, the central part of impeller forms vacuum area
Domain, the water at water source enters in water inlet pipe under the action of atmospheric pressure (or hydraulic pressure) later, recycles so endlessly, so that it may real
Existing continuous pumpage.Because water pump has, structure is simple, operation is easy, flow can easily be accommodated and is suitable for various special nature materials
Conveying the advantages that, be widely used in every field, big to each industrial site, as low as various household electrical appliance, such as washing machine is washed
Bowl machine, air-conditioning etc..
Traditional water pump, impeller are typically in closed chamber, and not only structure is complicated, and processing request is also higher.
A kind of dish-washing machine using open water pump of the European Patent Publication of Publication No. EP0807396A2 comprising for accommodating
The washing chamber of plate is supported on the spray arm of washing chamber bottom, pumps out the pump that cleaning solution pressurizes to spray arm, and pump includes impeller,
The inner surface of spray arm defines the shell for impeller, allows nozzle of the cleaning solution from shell to spray arm to be transmitted, leaf
Wheel is included in prone first blade in lower edge, and the bottom of the first blade has the first blade-section of axial-flow type,
After the non-loaded lower starting of driving motor, the first blade-section of axial-flow type lifts fluid, so that pump be made to be worked normally.So
And this impeller, the curved lower section of the first blade are shorter, the rotation of the first blade is needed when drawing water in higher water level, water outlet
Water route is shorter, is easy that impeller will be involved in again in the foam of the formation such as water for cleaning surface washing liquid, swill, influences normal
Draw water, and the water to draw water is less, and flow velocity is lower, impacts so that work can be normally sprayed to rotation gushing arm.
To solve the above-mentioned problems, Authorization Notice No. is a kind of Chinese patent " open water pump " of CN104235061B
(application number: CN201310750285.6) discloses a kind of structure comprising upper housing, lower case and impeller, impeller include position
Multiple the first blades axially extended being uniformly distributed circumferentially on axis in center and the circumferential surface in axis, the first blade is in axis
It is divided into upper section and lower section interconnected upwards, the upper accommodating cavity of the first blade upper section of accommodating, lower casing is formed in upper housing
The lower accommodating cavity of the first blade lower section of accommodating is formed in body, the water inlet of water pump is located at the lower section and side of lower case, out
The mouth of a river is located at the side of upper housing, the bottom of the first blade at least its lower section on the circumferential surface of axis along the direction of rotation of impeller gradually
Smooth curved, the lower section height of the first blade and the height ratio of upper section height are 1~5.Above-mentioned impeller can be drawn compared with low water level
Water, it is not easy to the foam that the cleaning solution of water surface or swill are formed is involved in impeller and influence to draw water, and can be from entering
Draw enough flows in the mouth of a river.But since the first blade for axially drawing water and for Centrifugal dispersion is integrally formed, and
The first blade-section for axially drawing water is shorter, during drawing water, when the vacuole carried in liquid develops to a certain extent
Just influence whether that the characteristic of the first blade outer rim declines performance, this is because the liquid in the runner for being centrifuged the first blade is
By axial direction to Radial Flow, and the density ratio gas of liquid is big, and under the influence of centrifugal force, the vacuole in liquid is easily separated
Out, it and expands rapidly to block runner, drastically reduces the intake performance of pump, and then influence water discharge speed.
