Embodiment Construction

[0025] The present invention will be further described in detail below with reference to the embodiments of the accompanying drawings.

[0026] The volute structure of this embodiment is suitable for a double-pump system, that is, a pump system that can provide bidirectional power. The double-pump system can be applied to a dishwasher with a larger volume, and is a bottom spray, a top spray and / or a middle spray. Of course, the use of water is not limited to this environment.

[0027] like Figures 1 to 5 As shown, the volute structure of this embodiment includes an upper casing 3 and a lower casing 4, the upper casing 3 has a body extending in the longitudinal direction, and the central part of the body has a In the first accommodating cavity 31 , two sides of the main body respectively have flow channels communicating with the first accommodating cavity 31 , and the top wall of the upper casing 3 is provided with spray holes communicating with the flow channels. The lower ...

Abstract

The water pump volute comprises an upper shell body and a lower shell body, the upper shell body is provided with a first containing cavity used for installing the upper portion of a first power component, and the upper portion of the lower shell body is provided with a second containing cavity used for installing the lower portion of the first power component. The side lower portion of the lower shell is provided with a third containing cavity used for installing a second power component, the bottom of the lower shell is provided with a second water inlet allowing water to enter the third containing cavity, and the side of the lower shell is provided with a water outlet allowing water to be output from the third containing cavity. The second containing cavity and the first containing cavity supply water to the bottom in a spraying mode, the third containing cavity supplies water to the top and / or the middle in a spraying mode, power of two paths of water flow is independently supplied by corresponding pumps, the lift and the water flow of each path of water flow are improved, and the cleaning effect is improved. And the molded line corresponding to the third accommodating cavity is formed by fitting a curve passing through at least four points, so that the third accommodating cavity forms a flow channel structure which is gradually expanded along the water flow flowing direction, the pressure of discharged water is favorably increased, the lift is improved, and the requirement of high-position water flow conveying is met.

Description

technical field [0001] The invention relates to the technical field of dishwasher accessories, in particular to a water pump volute used for a washing machine. Background technique [0002] A dishwasher is a device that sprays cold or hot water onto dishes to remove dirt adhering to them and to clean them. At present, the common dishwashers on the market include desktop, cabinet, sink, etc. Among them, only the sink type dishwasher uses an open water pump, that is, the water pump is combined with the spray arm, and the spray arm is used as the pump volute. At the same time, it takes into account the functions of drawing water and spraying water column, which is convenient for disassembly and cleaning, and maintains a good water flow effect. [0003] The applicant's previous application ZL201310752030.3 "Open Sink Cleaning Machine" discloses the above water pump structure, the rotating spray arm is used as the water outlet part of the water pump, and the middle bottom is for...
