[0021] Embodiment 1

[0022] In the prior art, when staff conduct performance testing on a drainage pump, they can only conduct performance testing on one drainage pump at a time. Although a sampling test method is adopted, it still takes a lot of time, and a lot of water is consumed during the test process, which leads to an increase in the economic cost of washing machine production. In order to solve the technical defect existing in the prior art, the present embodiment proposes a washing machine drain pump detection device, which can perform performance detection on multiple drain pumps at one time, and can effectively improve the detection efficiency. A pump body 2 to be tested is placed on the detection box 1 of the device, and a performance detection mechanism 3 for detecting the drainage capacity of the pump body 2 to be tested is provided on the detection box 1. A water source recovery mechanism 4 for recovering resources and avoiding waste is provided on the side of the detection box 1. After the staff puts the pump body 2 to be tested on the top of the detection box 1, the performance detection mechanism 3 will automatically detect the drainage capacity of the pump body 2 to be tested. At the same time, the water source recovery mechanism 4 will recycle the water generated during the detection process to avoid waste of resources. Specifically, the performance detection mechanism 3 includes a vertical cavity 301 opened at the upper end of the detection box 1, a water storage tank body 302 is fixedly installed on the outer side of the vertical cavity 301, and a plurality of detection water pipes are evenly spaced inside the vertical cavity 301. 303, the detection water pipe 303 is connected to the interior of the water storage tank body 302, and a limit baffle 304 for fixing the detection water pipe 303 is arranged inside the vertical cavity 301. A mounting protrusion 305 is fixedly installed on the upper end of the detection box 1, and a flow meter 306 is arranged on the mounting protrusion 305. After the pump body 2 to be inspected is energized, clean water will be extracted from the interior of the water storage tank body 302 through the detection water pipe 303, and the extracted clean water will be discharged outward through the flow meter 306. During the process, the flow meter 306 will detect the flow rate and flow velocity of the clean water. A power supply circular groove 307 for supplying power to the pump body 2 to be inspected is provided on the detection box 1. After the staff puts the pump body 2 to be inspected on the top of the detection box 1, the power supply connector of the pump body 2 to be inspected will be inserted into the power supply circular groove 307 for power supply. A dust cover 308 is movably installed on the outer side of the vertical cavity 301, which can effectively prevent dust and other impurities from entering the interior of the vertical cavity 301.

[0023] In order to recycle water resources and avoid waste, the present embodiment is provided with a water source recovery mechanism 4. Specifically, the water source recovery mechanism 4 includes a water receiving cavity 401 provided on the detection box 1, and the mounting protrusion 305 is located on the inner side wall of the water receiving cavity 401. The number of flow meters 306 matches the number of detection water pipes 303, and the drainage capacity of multiple pump bodies 2 to be tested can be tested at the same time, with high detection efficiency. A suction water pump 402 is fixedly installed on the outside of the detection box 1. The suction water pump 4 The liquid inlet end of 02 is connected with a drainage elbow 403, and the liquid outlet end of the suction pump 402 is connected with a water supply pipe 404. After the clean water enters the water receiving cavity 401 through the flow meter 306, it will return to the inside of the water storage tank 302 under the action of the suction pump 402.

[0025] Next, the pump body 2 to be inspected will be powered on and operated. When the pump body 2 to be inspected is working, the clean water inside the water storage tank 302 will be sucked out through the detection water pipe 303. Then, the clean water will flow into the water receiving cavity 401 through the flow meter 306. During the suction process, the flow meter 306 will automatically monitor and count the drainage volume and drainage speed of the pump body 2 to be inspected. At the same time, the staff will observe and analyze the data measured by the flow meter 306 on the terminal device, thereby completing the inspection work of the pump body 2 to be inspected.
