The application discloses a water pump control method and device, household electrical appliances and storage medium. The water pump is located in a water receiving tray of a target device and is used for draining water in the water receiving tray. The method comprises the following steps: obtaining water production flow of the target device; determining the running condition of the target device according to the water production flow; determining the target start-stop working time of the water pump according to the running condition; wherein the target device comprises multiple running conditions, and different running conditions correspond to different target start-stop working times; and controlling the water pump according to the target start-stop working time. Therefore, the water pump is controlled by using corresponding target start-stop time according to different running conditions, so that the service life of the water pump can be improved without affecting the water drainage performance of the target device, and the actual service life of the target device is improved.

The utility model discloses a pre-buried clean floor drain not easy to block and seep water, which comprises a shell structure used for performing multi-stage sealing pre-burying on the ground, a detachable sinking type filter basket is further arranged in the shell structure, the shell structure comprises a shell body, a countersunk head groove is arranged on the upper side in the shell body, and the countersunk head groove is arranged in the shell body. A connecting ring is further arranged on one side of the outer surface of the outer shell, a transverse filling groove is formed in the surface of one side of the connecting ring, a longitudinal filling groove is formed in the surface of the other side of the connecting ring, an auxiliary water outlet pipeline is further arranged on one side of the outer shell and communicates with a main water outlet pipeline, and the main water outlet pipeline is connected with a main water outlet. According to the invention, the sealing performance is enhanced, the phenomena of glue failure, crack and water seepage at the joint are not easy to occur, the influence of accumulated water on the ground is reduced, the breeding of bacteria in gaps and the generation of peculiar smell are reduced, and unsmooth water discharge caused by accumulation of solid impurities at the ground water inlet is avoided.

This utility model discloses a sideless inverter air-cooled heat pump air conditioning unit chassis, including a chassis base plate, a front crossbeam, and a rear crossbeam. Corner block connectors are provided around the bottom of the chassis base plate, and the front and rear crossbeams are installed on the front and rear sides of the chassis base plate via these corner block connectors. A heat exchanger support longitudinal beam and several compressor support longitudinal beams are provided between the front and rear crossbeams; these beams are respectively located on the left and right sides between the front and rear crossbeams. This sideless inverter air-cooled heat pump air conditioning unit chassis of this utility model greatly expands the direction of on-site piping, allowing piping to be connected from both the left and right sides, providing significant convenience for on-site installation.
