referring to fig. 5, the drawer structure 2 carrying the rice cooker 4 is pushed into the box body 1, and the handle on the cover 42 of the rice cooker is pushed into the fork of the second swing link 537. When the cooker needs to be weighed, the opening and closing lifting motor 532 is started to drive the opening and closing lifting screw rod 533 to rotate so as to drive the opening and closing lifting plate 535 to move upwards, so that the cover body 42 is moved upwards through the second swing rod 537 to be separated from the cooker body 41. The second swing lever 537 is driven to rotate by the second rotation driving motor 536 to move the cover 42 away. Then the lifting rod 31 is started to ascend to enable the electric cooker 4 to ascend, the five-ring socket 34 is separated from the five-ring plug 35, the weighing sensor 33 ascends simultaneously and is contacted with the bottom of the electric cooker 4, at the moment, the independent support of the cooker body 41 of the whole electric cooker 4 is placed on the weighing sensor 33 to achieve weighing, and corresponding signals are sent to the rice adding device 6.

The rice feeding device 6 starts to feed rice, when the set amount is reached, the weighing sensor 33 sends a signal to enable the rice feeding device 6 to stop feeding rice, then the elutriation device 8 which receives the signal is put into the rice cooker 4, water feeding is started after stopping above the rice flour, when the set amount is reached, the weighing sensor 33 sends a signal to enable the water feeding and discharging system 7 to stop feeding water, the elutriation device 8 is started to continue to put into the rice, then the water feeding and discharging stirring rod 871 is started to rotate and stir the rice for washing, and after the elutriation is finished, the water feeding and discharging system 7 is started to pump the rice washing water for discharging. When the set amount is reached, the weighing sensor 33 sends a signal to enable the water inlet and outlet system 7 to stop pumping water, and rice washing is repeatedly carried out. After the rice washing and the rice cooking are finished, the washing device 8 retracts and resets, the lifting rod 31 is started to retract and reset, the five-ring plug 34 is inserted into the five-ring socket 35 at the bottom of the electric cooker 4, the electric cooker 4 is supported by the supporting block 38, and the cooker body 41 of the electric cooker 4 is separated from the weighing sensor 33. The lid 42 is rotated to the upper side of the pot body 41 by the second rotation driving motor 536, and the lid 42 is driven to move downward by the opening and closing elevating motor 532, so that the lid 42 is returned to the original position and covered on the pot body 41, and then the cooking is started. After cooking, the drawer structure 2 is pulled out, and the electric cooker 4 is taken out to contain the rice.

In conclusion, the lifting type rice cooker is lifted or lowered through the lifting type weighing system, so that the whole rice cooker is weighed, the weight information can be detected in real time through the weighing sensor when rice and water are added, the added rice amount and the added water amount are calculated, the added rice amount and the added water amount are controlled, the detection and control precision is improved, quantitative rice cooking is achieved, the requirement of automatic rice cooking is met, and manual operation is reduced.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
