Description

Technical Field

[0001] The utility model relates to the field of washing machine drainage pumps, and more specifically, to a washing machine drainage pump filter installation structure. Background Art

[0002] At present, the drain pumps of washing machines are equipped with filters, which have filtering functions to prevent foreign matter from flowing into the drain pump with water and damaging the impeller in the drain pump; the filter is made of plastic as a whole, and can be removed and cleaned after a period of use and then reinstalled for use; the shell structure of the current washing machine drain pump is basically as follows: Figure 1 , Figure 2 As shown, when assembling the filter into the drain pump housing, the protruding positioning block (6) on the filter needs to be aligned with the positioning groove (1) on the drain pump housing, otherwise the filter cannot be accurately and smoothly installed in place; the top of the existing positioning groove (1) is connected to the linear guide groove, and its opening extends to the top of the drain pump housing; however, in actual application of the washing machine, the drain pump is located at the lower right bottom of the washing machine. The user cannot conveniently and accurately align the positioning groove during installation, and needs to rotate and test to align the linear guide groove (2). Moreover, many users do not know that they need to align the linear guide groove (2) for installation. Since the drain pump housing is a plastic structure, the filter can be squeezed in with a little force without actually aligning the linear guide groove (2), causing the filter to be squeezed and stuck. First, the filter components are damaged, which may further cause water leakage; second, the filter is difficult to take out for cleaning next time. Utility Model Content

[0003] The purpose of the utility model is to provide a technical solution for the filter installation structure of a washing machine drainage pump to solve the above problems;

[0004] The utility model provides a filter installation structure for a washing machine drainage pump, comprising a pump body, characterized in that a positioning groove (1) is arranged at the bottom of the pump body side wall (4), and an arc-shaped guide groove (3) is arranged at the upper end of the positioning groove (1).

[0005] Preferably, the positioning groove (1) and the arc-shaped guide groove (3) are one or more. When there are multiple arc-shaped guide grooves (3), they are evenly distributed on the side wall (4).

[0006] Preferably, the arc guide groove vertex (31) where the arc lines of the arc guide groove (3) intersect is located below the bottom end of the pump body connector (5), leaving a gap with the bottom end of the connector (5), and the arc guide groove (3) is smoothly arranged along the entire pump body side wall (4).

[0007] According to the present solution, no matter from which angle the filter is installed into the pump body, the filter positioning block (6) will automatically slide into the positioning groove (1) along the arc-shaped guide groove (3), and there is no need to rotate and try to align the arc-shaped guide groove (3). For users who do not know the required alignment position, there is no problem of wrong installation.

[0008] Beneficial effects of the utility model:

[0009] 1. Makes the installation of the filter simpler and more accurate;

[0010] 2. It can effectively avoid the risk of wrong installation of the filter, as well as the risk of leakage, damage and other market risks caused by wrong installation;

[0011] 3. Greatly improved customer after-sales defects and after-sales maintenance costs.
