Problems solved by technology

[0005] Therefore, a circulation pump and a drainage pump are generally installed on existing washing machines with external circulation function. Since the circulation pump and the drainage pump are set independently of each other, not only a large amount of space inside the washing machine is taken up, but also the circulation pump and the drainage pump need to be installed. The drainage pumps are installed separately, which increases the production process of the washing machine and reduces the production efficiency

Embodiment 1

[0042] like Figure 1 to Figure 12As shown, this embodiment introduces a double-head pump, which includes a main pump body 1 in the shape of a column, and a filter element 9 extending along the axis is arranged in the main pump body 1, and the filter element 9 divides the main pump body 1 into parts to be The filter cavity 17 and the filtered cavity 18; one end of the main pump body 9 is provided with a drainage pump cavity 7 which connects the to-be-filtered cavity 17 and the filtered cavity 18. The drainage pump cavity 7 is equipped with a drainage pump 5, and the drainage pump cavity 7 is a The side is connected to the drain pipe 3, and the drain pump 5 guides the inlet water from the water inlet pipe 2 in the main pump body 1 directly to the drain pipe 3 through the drain pump cavity 7 to flow out; the other end of the main pump body 1 is provided with a cavity to be filtered. The water inlet pipe 2 communicated with 17 and the circulating pump chamber 8 communicated with ...

Embodiment 2

[0057] like Figure 1 to Figure 8 As shown, this embodiment introduces a double-head pump casing structure, which includes a columnar main pump body 1, and two ends of the main pump body 1 are respectively provided with a water inlet pipe 2 and a drainage pump cavity 7, which are close to the water inlet pipe. 2 The side wall of the main pump body 1 at one end is provided with a circulating pump cavity 8; the water inlet pipe 2 and the circulating pump cavity 8 are staggered at a certain angle, and respectively protrude outward along the radial direction of the main pump body 1; The end is provided with a circulating pump installation joint 14, the side wall of the circulating pump cavity 8 is provided with a circulating water outlet pipe 4 that protrudes outward in the radial direction; the drainage pump cavity 7 is provided with a drainage pipe 3 and a drainage pump installation joint 15 , the drain pump installation joint 15 protrudes and extends outward along the axial dir...

Embodiment 3

[0072] like figure 1 and Figure 7 to Figure 12 As shown, in this embodiment, a filter element for a double-head pump is introduced. The double-head pump includes a circulating pump cavity 8 for installing the circulating pump 6, and a drainage pump cavity 7 for installing the drainage pump 5; the filter element 9 includes a bracket, One end of the bracket is provided with a first filter structure for filtering the water flow into the drainage pump cavity 7 , and a second filter structure for filtering the water flow into the circulating pump cavity 8 is also provided on the bracket.

[0073] By arranging the above-mentioned filter element, the double-head pump can be filtered separately when the circulating pump and the drain pump are used, so as to realize the purpose of filtering the influent water with corresponding and different requirements before flowing into the corresponding chamber and then outflow, avoiding the water flow. The foreign matter flows into the pump cav...

Abstract

The invention relates to a double-head pump casing structure and a washing machine. The double-head pump casing structure comprises a columnar main pump body, the main pump body is connected with a water inlet pipe, and the main pump body is provided with a circulation pump for installing a circulating pump. The pump chamber, one side of the circulating pump chamber is provided with a circulating water outlet pipe, and the inner wall of the circulating pump chamber is provided with an inclined surface that guides the water flow in the chamber to the circulating water outlet pipe, so as to guide the inlet water to the circulating water outlet pipe to flow out. By setting an inclined surface at the bottom of the circulating pump cavity, the water flow from the bottom of the cavity is guided to flow to the circulating water outlet pipe along the inclined surface, so as to avoid the accumulation of lint, sediment, etc. in the circulating water at the bottom corner of the circulating pump cavity. occurrence, thereby improving the working efficiency of the circulating pump, reducing the abnormal noise and reducing the working noise. At the same time, the circulating water outlet pipe is arranged on the top of the circulating pump cavity, so that the gas at the top of the circulating pump cavity will be discharged together with the water flow, so as to avoid the occurrence of air resistance in the circulating pump cavity.

Description

technical field [0001] The invention relates to a double-head pump in the field of mechanical manufacturing, in particular to a double-head pump casing structure, and in particular to a double-head pump applied to a washing machine. Background technique [0002] The pump casing structure used in the washing machine is usually a circular section, and in a double pump head casing structure (that is, the casing of the drainage motor and the circulation motor is connected at the same time), this circular section is bound to increase the pump. The overall volume of the body causes waste of space and cost. For this problem, we designed a double pump head shell structure with a circular section. [0003] Among existing products, washing machines equipped with an external circulation system are very common. The external circulation pipe is connected to the water outlet of the washing machine's water tub, and the other end of the external circulation pipe is connected to the circulat...
