Abstract

This invention relates to an automatic lifting rice cooker, belonging to the field of electrical technology. In the lifting operation state, the lifting motor terminal 207 connects to the main control terminal 201, driving the lifting motor 400 to operate. The rotation of the lifting motor screw 401 causes the lifting motor nut 403 to rotate, which in turn drives the lifting nut 402 to pull the inner lifting connecting column 305. This causes the inner lifting connecting column sliding hole 308 to travel through the outer lifting connecting column sliding hole 306, thus driving the lifting box 4 lifting box connector 303. This compression drives the rice washing rod 52, rice washing rod blades 51, lower water outlet pipe 32, water outlet filter hole 31, lower water inlet pipe 42, and lower water inlet 41, bringing them to near the bottom surface of the inner pot. This effectively improves the rice washing efficiency of the rice washing rod 52, rice washing rod blades 51, lower water outlet pipe 32, lower water inlet pipe 42, and lower water inlet 41.

People hope to automate traditional cooking methods in a convenient and simple way. To address these issues, the inventor has invented an automatic lifting and washing rice cooker. Summary of the Invention

[0003] To address the aforementioned problems, the present invention is achieved through the following technical solution; It has automatic water intake, water output, and rice washing functions for rice cookers. It consists of: outer shell, middle layer, heater, inner pot, lid, water inlet pump, water outlet pump, water inlet pipe, water outlet pipe, rice washing motor, lifting box, outer lifting connecting column, inner lifting connecting column, outer lifting connecting column sliding hole, inner lifting connecting column sliding hole, and lifting motor.

[0004] The inner pot is enclosed within the outer shell and the lid.

[0007] The outer lifting connecting column is sequentially installed and connected to the inner lifting connecting column and the inner lifting connecting head.

[0008] The socket is equipped with a connector plug. The socket does not have socket terminals; the socket terminals are connected to the main control terminals.

[0010] The lifting box is equipped with a connector plug, which has connector terminals that are sequentially connected to the water outlet pump terminal, the water inlet pump terminal, and the rice washing motor terminal.

[0011] The lifting box is installed with a lifting box connector, the lifting box connector is installed with an inner lifting connector, the inner lifting connector is connected to an inner lifting connecting column, the inner lifting connecting column is connected to a lifting nut through a sliding hole, the lifting motor screw thread is installed with a lifting nut thread, the lifting motor screw thread is connected to the lifting motor screw thread, the lifting motor screw thread is connected to the lifting motor, the lifting motor end is connected to the main control terminal, and the lifting motor is installed and connected at the position of the lifting connecting column.

[0012] The inner lifting connector, inner lifting connecting column, lifting nut, lifting motor screw, and sliding hole are installed in the outer lifting connecting column.

[0013] The inner pot is equipped with a lower water outlet pipe, a lower water outlet filter hole, a lower water inlet pipe, a lower water inlet, a rice washing stem, and rice washing stem leaves.

[0014] When using the automatic lifting rice cooker described above: Rice is placed into the inner pot for preparation. The middle layer is embedded inside the outer shell, and the inner pot is placed in the middle layer. The inner pot containing the rice is then placed inside the middle layer. The lifting box is equipped with a water pump, water outlet, upper water outlet pipe, water pump terminal, water inlet pump, upper water inlet pipe, upper water inlet, water pump terminal, rice washing motor, rice washing motor terminal, plug, plug terminal, and lifting box connector. These components are installed in the inner lifting connector, where the plug terminal is coupled to the socket terminal, connecting to the main control terminal in standby mode. The rice washing rod, rice washing rod blades, lower water outlet pipe, water filter hole, lower water inlet pipe, and lower water inlet are placed in the inner pot.

[0015] In lifting operation mode; the lifting motor terminal is connected to the main control board, driving the lifting motor to work. This drives the lifting motor screw to rotate, causing the lifting motor teeth to rotate. The rotation of the lifting motor teeth causes the lifting nut to pull the inner lifting connecting column, moving the inner lifting connecting column slide hole through the outer lifting connecting column slide hole. This causes the lifting box to compress, which in turn compresses the plug. The compressed plug connects to the socket, and the compressed socket connects to the coupling plug terminals. The plug terminals connect to the water pump terminal, the water inlet pump terminal, and the rice washing motor terminal. (Standby mode)

[0017] When the rice washing process is in operation, the water pump starts its working program, and the rice washing water is sequentially drawn into the inner pot through the upper water inlet, upper water inlet pipe, lower water inlet pipe, and lower water inlet. At the same time, the rice washing motor starts its working program, and the rice washing rod rotates, driving the rice washing rod blades to stir and wash the rice, thus achieving the desired washing effect.

[0018] Rice washing water output status: The water pump starts working, and the water after washing the rice passes through the lower water filter hole, the lower water pipe, the upper water pipe, and the water outlet in sequence for self-priming output. The diameter of the water filter hole is smaller than the diameter of most rice grains to prevent rice from being accidentally discharged.

[0019] Cooking begins; the water pump restarts, and water for cooking flows into the inner pot through the upper inlet, upper inlet pipe, lower inlet pipe, and self-priming inlet. The heater starts, continuing the cooking process. When the sensor at the bottom of the pot detects the set temperature, it transmits the signal to the main control board's drive circuit, stopping the cooking process and initiating the keep-warm program.

[0020] The beneficial effects of this invention are This invention provides an automatic lifting rice cooker. The effects described above are: simplified rice cooking by automating water intake, output, and rice washing processes, thus solving problems such as time-consuming, labor-intensive, and low-automation operation. Effective control of water intake and output improves cooking efficiency and produces beneficial results. Attached Figure Description

The drive screw 401 rotates, causing the lifting motor nut 403 to rotate. The rotation of the lifting motor nut 403 causes the lifting nut 402 to pull the inner lifting connecting column 305. This causes the inner lifting connecting column sliding hole 308 to travel through the outer lifting connecting column sliding hole 306. This, in turn, causes the lifting box 4 and lifting box connector 303 to compress and drive the rice washing rod 52, rice washing rod blade 51, lower water outlet pipe 32, water outlet filter hole 31, lower water inlet pipe 42, and lower water inlet 41, traveling to near the bottom surface of the inner pot.
