Problems solved by technology

[0002] At present, the development of the toilet flushing structure is mostly carried out through trial and error. The improvement of the flushing efficiency depends on the trial, repair and retesting of the mold one after another. Therefore, there is a lot of randomness in the quality of the flushing efficiency. and contingency, which lead to a long development cycle and large errors in factors. In addition, it is difficult to apply modern optimization algorithms to achieve optimal design without digital modeling of toilet flushing structure.

Description

technical field [0001] The invention relates to the field of toilet simulation design, in particular to a toilet flushing efficiency evaluation method. Background technique [0002] At present, the development of the toilet flushing structure is mostly carried out through trial and error. The improvement of the flushing efficiency depends on the trial, repair and retesting of the mold one after another. Therefore, there is a lot of randomness in the quality of the flushing efficiency. And contingency, this results in a long development cycle and large errors due to factors. In addition, it is difficult to apply modern optimization algorithms to achieve optimal design without digital modeling of toilet flushing structure. Therefore, how to complete the flushing performance evaluation of the design scheme in the toilet design stage, so as to reduce the mold trial and mold repair links, has become an urgent problem to be solved. Contents of the invention [0003] The technic...
