When either result of step 440 and step 441 is no, a warning signal is indicated on the control panel 132′ (step 445).

If the cooking function is selected in step 404, step 405 is performed for using the pot sensor 127′ to determine whether the pot 125′ is properly positioned. When the result of step 405 is yes, step 406 is performed for using the door sensor 124′ to determine whether the door plate 123′ is properly closed. When the result of step 406 is yes, step 407 is performed for using the drinking water sensor 107′ to determine whether the drinking water is adequate. When the result of step 407 is yes, step 408 is performed for using the food sensor 111′ to determine whether the food items in the food storage tank 110′ is adequate. When the result of step 408 is yes, the food valve 115′ is opened for delivering a predetermined amount of food items (step 409) by the food valve 115′.

In step 410, if direct cooking is selected, the food items will be delivered to the pot 125′ through the first food output member 114′. If grinding of food items is selected, step 411 is performed in which the food items are delivered to the grinding arrangement 32′ through the second food output member 31′. The grinded food items are then delivered to the pot 125′ (step 412). In step 413, if direct cooking of the grinded food items is selected, the grinded food items are delivered to the pot 125′ through the third food output member 33′. If the answer is no in step 413, the drinking water valve 105′ is opened (step 414) and a predetermined amount of drinking water is also delivered to the pot 125′ for mixing with the food items (step 415).

Step 415 and step 410 merge with step 416. In step 416, the pot sensor 127′ determines whether or not a correct amount of drinking water and food items are stored in the pot 125′. When the result of step 416 is yes, the food valve 115′ and the grinding arrangement 32′ are turned off (step 417), and the drinking water valve 105′ is opened for delivering the drinking water (step 418) to the pot 125′. Thereafter, step 419 is performed for using the pot sensor 127′ to determine whether the amount of the drinking water in the pot 125′ is correct. When the result of step 419 is yes, the drinking water valve 105′ is closed (step 420), and the pot 125′ is closed (step 421) and a heating mode is activated for the heater 126′ to heat up the drinking water and the food items in the pot 125′ (step 422).

Step 423 determines whether or not ultrasonic vibration needs to be performed by the ultrasonic vibration generator 34′. If the answer is yes, the ultrasonic vibration generator 34′ is activated (step 424). If no, the step 425 is performed to determine whether or not the pot 125′ has reached a threshold temperature by the use of the temperature sensor 35′. If the temperature has reached a predetermined threshold, and the pressure of steam inside of cooking cavity reach a proper level, the step 426 is performed to activate the air release valve 155′ for releasing of steam from the pot 125′. When the temperature has not reached the predetermined threshold, step 422 is performed again.

Then, step 427 is performed for using the controller 130′ to determine whether or not cooking is finished properly. When the result of step 427 is yes, the cooking is ended (step 428), and the heater 126′ is switched to the warming mode (step 429), and the door plate 123′ is opened (step 430), and the heater 126′ is turned off for safety reason (step 431). The pot 125′ is opened (step 432) and the entire cooking process will end (step 433).

In the entire operation process, as long as abnormality occurs, warning and reminding will be issued to the user (step 445), thus ensuring that each step has been properly performed before entering the heating mode or the warming mode. Thus, for step 410 and step 413, if the determination is yes, step 416 is subsequently performed. In step 416, when the determination by the pot sensor 127′ is no, step 409 is re-performed. In step 419, when the determination by the pot sensor 127′ is no, step 418 is re-performed. In step 425 and step 427, when the determination by the controller 130′ is no, step 422 is re-performed.

It is worth mentioning that a user may control and monitor the operation of the automatic cooking apparatus by inputting instructions through the control panel 132′ and or the remote control unit 134′. The central processing module 133′ is arranged to control and coordinate all the operations of the automatic cooking apparatus. The user may operate the automatic cooking apparatus in at least one of the water supplying mode and the cooking mode. Both modes of operation can be performed simultaneously in which drinking water is dispensed through the first water dispensing outlet 1042′ and the second water dispensing outlet 1043′.
