When the rice cooking device is used, firstly, a power-on initialization, a communication module, a liquid crystal display module, a weighing module and the like are initialized, then, whether a local timing is set by a user or not is controlled and inquired, if the local timing is not set, remote timing data of the user are waited to be acquired, if the local timing of the user is set, the remote timing is not reached before a specified time, rice cooking is started at the local timing time, if the timing data are transmitted by the user remotely before the local timing of the user, the timing data transmitted by the user are used for carrying out rice cooking operation, and finally, when the local state data are required by the user, the local state data are transmitted to the user, and the main state data comprise the weight of the rice storage barrel 2, the state of rice at the moment and the like.
When the rice cooking time is reached, calculating the required rice amount according to the rice cooking amount set by a user, wherein the rice amount is also equal to the mass difference value of the rice storage barrel 2 measured twice, and when the rice amount is put into the calculated value, the motor of the third driving device 13 rotates to close the upper cover 3 to block the rice storage barrel 2 and the sieve barrel 4;
At this time, the rice in the screen barrel 4 is equal to the calculated value, the rice is washed, the second driving device 10 drives the ball screw 11 to rotate forward, the screen barrel 4 descends to a certain height in the rice washing barrel 5, then the water inlet valve is opened, the water inlet valve is closed after the rice in the rice washing barrel 5 reaches the height for which the rice in the screen barrel 4 is not used, at this time, the first driving device 9 fixedly connected with the rice washing barrel 5 starts the variable speed movement, the clean water in the variable speed movement drives the rice in the screen barrel 4 to move, the purpose of washing the rice is achieved, after washing for a certain time, the second driving device 10 drives the ball screw 11 to rotate reversely, the screen barrel 4 ascends under the action of the ball screw 11, but at this time, the wedge-shaped groove of the nut 12 on the ball screw 11 does not ascend to match with the wedge-shaped block of the ball screw 11, and then the water drainage valve action discharges the rice water;
After washing rice, washing rice 5 will wash once, open the water inlet valve at first, after entering a certain amount of water, the water inlet valve stops acting, wash rice 5 motor action thereafter, wash rice 5 variable speed movement drive water flow to achieve the purpose of washing, drain valve action after a certain time, wash rice 5 water drain after being clean, then enter the cooking link, after lowering the rice 5 to wash rice 5 certain height, according to the amount of water that the water inlet valve should enter of rice amount, then the water inlet valve stops acting, the heating device begins to heat washing rice 5, rice in the rice 4 is steamed, after the rice is boiled, wash rice 5 continue to heat and make rice in the rice 4 enter the thermal insulation mode;
When the user needs to take out the sieve barrel 4 to eat, the second driving device 10 drives the ball screw 11 to rotate reversely, so that the sieve barrel 4 ascends, when the wedge-shaped groove of the nut 12 on the ball screw 11 ascends to match with the wedge-shaped block of the ball screw 11, the nut 12 and the ball screw 11 are meshed, then the nut 12 and the ball screw 11 move relatively still, at the moment, the second driving device 10 drives the ball screw 11 to rotate 180 degrees continuously, then the sieve barrel 4 is rotated 180 degrees, no shielding object exists on the upper side and the lower side of the sieve barrel 4, and the sieve barrel 4 can be taken out conveniently.
Of course, each of the above steps can be controlled manually.
As a first alternative implementation of this embodiment, the third driving device 13 pushes the upper cover 3 to perform the opening and closing movement by using an electric push rod.
It is apparent that the above examples are given by way of illustration only and are not limiting of the embodiments. Other variations or modifications of the above teachings will be apparent to those of ordinary skill in the art. It is not necessary here nor is it exhaustive of all embodiments. While still being apparent from variations or modifications that may be made by those skilled in the art are within the scope of the invention.
