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

[0039] Such as Figure 1 to Figure 12 As shown, a double-head pump is introduced in this embodiment, which includes a columnar main pump body 1, 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 treated. Filtration chamber 17 and filtered chamber 18; One end of main pump body 9 is provided with the drainage pump chamber 7 that will be connected to filter chamber 17 and filtered chamber 18, and drainage pump chamber 7 is equipped with drainage pump 5, and drainage pump chamber 7 The side is connected with the drain pipe 3, and the drain pump 5 guides the water inflow from the water inlet pipe 2 in the main pump body 1 directly to the drain pipe 3 through the drain pump cavity 7; the other end of the main pump body 1 is provided with a chamber to be filtered 17 is connected to the water inlet pipe 2 and the circulation pump chamber 8 connected to the filtered chamber 18, the...

Embodiment 2

[0054] Such as Figure 1 to Figure 8 As shown, this embodiment introduces a double-head pump shell structure, which includes a columnar main pump body 1, and the two ends of the main pump body 1 are respectively provided with a water inlet pipe 2 and a drain 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 chamber 8; The end is provided with a circulation pump installation joint 14, and the side wall of the circulation pump chamber 8 is provided with a circulating water outlet pipe 4 protruding radially outward; the drainage pump chamber 7 is provided with a drain pipe 3 and a drainage pump installation joint 15 , the drain pump installation joint 15 protrudes outward along the axial direction of the main pump body 1 , and the drain pipe 3 protrudes outward along the radial direction of the main pump body 1 .

[0055] Through the above settings, the circulation pump chamber and the d...

Embodiment 3

[0069] Such as figure 1 and Figure 7 to Figure 12 As shown, a double-head pump filter element is introduced in this embodiment. The double-head pump includes a circulation pump cavity 8 for the circulation pump 6 to install, and a drainage pump cavity 7 for the drainage pump 5 to install; the filter element 9 includes a bracket, One end of the bracket is provided with a first filtering structure for filtering the water flowing into the drainage pump chamber 7, and a second filtering structure for filtering the water flowing into the circulating pump chamber 8 is also provided on the bracket.

[0070] By setting the above-mentioned filter elements, the dual-head pumps can be filtered separately when using the circulating pump and the drainage pump, so that the influent water can be filtered according to different requirements and then flow into the corresponding chamber and then flow out, avoiding the need for water flow If foreign matter flows into the pump cavity, it will c...

Abstract

The invention relates to a double-head pump shell structure and a washing machine. The double-head pump shell structure includes a columnar main pump body connected to a water inlet pipe, and a circulation pump for the circulation pump to be installed on the main pump body. Cavity to guide the incoming water to the circulating water outlet pipe to flow out; the main pump body is also provided with a drainage pump chamber installed with the drainage pump to guide the incoming water to the drain pipe for discharge; the main pump body is placed horizontally, and The top of the main pump body is flat. By setting the top surface of the main pump body as a plane, the overall height of the main pump body is reduced on the premise of expanding the internal space of the main pump body as much as possible, so as to fully utilize the internal space of the washing machine and increase the washing capacity of the washing machine the goal of.

Description

technical field [0001] The invention relates to a double-head pump in the field of mechanical manufacturing, in particular to a shell structure of the double-head pump, 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 cross section, and in a double pump head casing structure (that is, the casing that connects the drain motor and the circulation motor at the same time), this circular cross section will inevitably increase the speed of 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 cross-section. [0003] Among the existing products, washing machines equipped with an external circulation system are already very common. The outlet of the washing machine's tub is connected to the external circulation pipe, and the other end of the external circulation p...
