Description
Technical Field
The invention relates to the technical field of motors, in particular to an operation control method of a blanking motor, operation control equipment of the blanking motor, a cooking appliance and a computer readable storage medium.
Background
In order to simplify the operation steps of the user and shorten the cooking waiting time, an automatic cooking appliance has been developed, which can automatically perform the processes of rice feeding, water feeding, rice washing water discharging, rice feeding into a pot, heating cooking, heat preservation and the like.
Among the correlation technique, set up the magazine of washing in cooking utensil, and wash the magazine and can communicate in storage portion, the material of storage portion internal storage is carried to washing in the magazine through the feeding line and is washd to discharge into the culinary art portion through the feed opening of washing the magazine and cook, and because wash the magazine and integrate inside cooking utensil, need additionally set up the sensor usually and detect whether the feed opening is opened or is closed, this production cost that can improve cooking utensil undoubtedly.
However, if not set up the sensor and detect feed opening or unloading motor, not only can't detect the open-close state of feed opening, also can't in time discover the trouble of unloading motor, on the one hand, in the abluent material of unwashed feed box directly gets into culinary art portion through the feed opening that can't close, influence user's diet health, on the other hand, at the culinary art in-process, the hot steam of culinary art intracavity flows back to storage portion through the feed opening that can't close, probably lead to the storage material to breed the bacterium or deteriorate, this all seriously influences the reliability of cooking utensil's automatic cooking function and user's use experience.
