[0022] As Figure 1 , Figure 3 and Figure 4As shown, the rear side of the center of the transparent observation plate 8 is provided with a storage washing device 7, which includes an internally threaded fixing cylinder 9, an externally threaded fixing cylinder 11, a corrugated booster cover 14 and a cylindrical liquid storage box 16. The internally threaded fixing cylinder 9 is inserted and fixed at the rear side of the center of the plastic upper cover 1. The externally threaded fixing cylinder 11 is screwed into the internally threaded fixing cylinder 9. The cylindrical liquid storage box 16 is arranged at the top end of the externally threaded fixing cylinder 11. The corrugated booster cover 14 is arranged at the top end of the cylindrical liquid storage box 16. The cylindrical liquid storage box 16 is in communication with the inside of the corrugated booster cover 14.

The front end of the cylindrical liquid storage box 16 is further provided with a capacity scale. The capacity scale is measured in milliliters. When installing and using the storage washing device 7, first screw the externally threaded fixing cylinder 11 into the internally threaded fixing cylinder 9 and tighten the externally threaded fixing cylinder 11 so that the bottom end of the cylindrical liquid storage box 16 tightly abuts against the outer wall of the top end of the plastic upper cover 1. Then, open the sealing cover 12 outside the liquid adding port 13 and inject washing liquid into the cylindrical liquid storage box 16 through the liquid adding port 13. After the injection is completed, reseal the sealing cover 12. When clothes are put into the washing machine, if it is necessary to add washing liquid, manually pressurize the storage washing device 7 through the corrugated booster cover 14. The pressurization will cause the self-contracting hole 10 in the self-contracting and closed state to be opened, so that the washing liquid in the cylindrical liquid storage box 16 flows out through the self-contracting hole 10. The washing liquid is injected into the washing machine drum in a measured amount according to the capacity scale on the front end of the cylindrical liquid storage box 16. The capacity scale is measured in milliliters. The remaining amount of washing liquid can be observed at any time. When the remaining amount is insufficient, the washing liquid can be supplemented in time.
