  • Patent number: 11959651
    Abstract: A method for cleaning an air conditioner includes: in response to a cleaning instruction, controlling frosting on the surface of a target heat exchanger; after a frosting completion condition is met, controlling defrosting of the frost on the target heat exchanger; and after a defrosting completion condition is met, reducing the surface temperature of the target heat exchanger to a sterilization temperature, and carrying out quick cooling sterilization, wherein the temperature difference between the sterilization temperature and the defrosting temperature during defrosting meets a set temperature change sterilization condition. By a frosting-defrosting process, dirt such as dust on the heat exchanger may be effectively stripped and deep bacteria may be exposed, and then the quick cooling sterilization process may kill the bacteria by utilizing the sharp temperature change during switching from the defrosting process to the quick cooling process. Also disclosed is the air conditioner.

  • Patent number: 11630432
    Abstract: A tool path generation method for a bidirectional cutting edge tool, comprising: first obtaining a driving line and an auxiliary driving line of a contour, and discretizing the driving line to obtain tool position driving points; obtaining a tool axis vector according to a rule plane of the driving points and the auxiliary driving line; and then, calculating a tool position point according to geometric dimensions of the tool so as to obtain a tool path of a machining contour of the bidirectional cutting edge tool. The problems of fiber delamination and fluffing, burr generation, and the like of the contour of a machined part can be avoided, and the machining quality of a contour surface is improved, and the low-cost machining of parts can be efficiently achieved.
