Problems solved by technology

However, due to the smooth surface of the existing combined blade structure, the water flow disturbed by the impeller rotation is mostly laminar flow, and the washing water and water are not easy to mix, so that the detergent does not work well, and the cleaning ability is not good. The problem

Embodiment Construction

[0030] It should be understood that directional terms such as up, down, left, right, up, down, left, and right in this specification are descriptions for the orientations shown in the drawings, and these orientations are not limiting. If not specifically stated, the terms inward, outward, inner, outer, inner, and outer refer to the range relative to the center of the component, for example, taking the motor axis as a reference, and inner and inner refer to positions that are closer to or point to the motor axis Or orientation, outboard and outboard refer to parts that are farther from the center of the motor. Furthermore, the terms horizontal, erect, overhang, etc. do not mean that the part is required to be absolutely level or overhang, but a slight inclination is allowed. For example, horizontal only means that its direction is more horizontal than vertical, and does not mean that the structure should be completely horizontal, but can be slightly inclined.

Abstract

The invention discloses a water pump impeller. The water pump impeller comprises a shaft sleeve which is positioned on the center for sleeving a rotary shaft and a plurality of blades which are uniformly distributed at the periphery of the shaft sleeve, wherein each blade is composed of an upper blade section and a lower blade section; the bottom of each upper blade section and the top of each lower blade section are separated from each other, and a gap for allowing a liquid to flow through is formed between the bottom of each upper blade section and the top of each lower blade section. According to the water pump impeller, turbulent flow is increased by disconnecting the upper blade section and the lower blade section of each blade of the impeller, so that a laminar-flow problem is solved. The upper section and the lower section of each blade are discontinuous, and water shifts in discontinuous gaps to form turbulent flow, so that a cleaning solvent and water are mixed to generate cleaning foams, and therefore, cleaning capacity is improved.

Description

technical field [0001] The invention relates to the technical field of water pumps, in particular to an impeller blade structure of the water pump. Background technique [0002] The impeller of the existing water pump is composed of many identical blades, and the blades are uniformly distributed around the rotating shaft in the circumferential direction. The blades can adopt different structural types according to functional requirements, such as axial flow blades, centrifugal blades, and so on. Combined blades have also appeared now, for example, one section is an axial flow type and the other is a centrifugal blade, and the two sections are combined with each other. For example, a dishwasher disclosed in European Patent Application Publication No. EP0807396A2 has an axial-flow blade at the bottom of the impeller blade and a centrifugal blade at the top, and the two parts are smoothly connected axially from bottom to top to form a whole blade. [0003] Another example is...
