Abstract
Description
Technical Field
[0001] The present invention relates to the field of household appliances, and particularly to an intelligent rice cooker that eliminates manual rice washing. Background Art
[0002] A rice cooker is a kitchen appliance for automatically cooking rice, and its core technologies include temperature control, heating, and intelligent cooking control. Traditional rice cookers use a metal inner pot in contact with an electric hot plate to heat, and adjust the temperature through a mechanical or electronic thermostat to make the rice fully absorb water and gelatinize.
[0003] Currently, when cooking rice with an intelligent rice cooker, users must manually take rice from the rice bin and complete the washing process, and cannot achieve true fully automated operation. In addition, if you want to remotely control the rice cooking through the APP, you must put the washed rice into the pot and add water in advance. However, the rice in the pot will be soaked for a long time, which will affect the taste. And if the reservation function is not set in advance, you can only start cooking after getting home, resulting in a long waiting time. What's more inconvenient is that if the number of diners is increased temporarily, users can only go home and prepare and cook again, and cannot flexibly adjust the amount of rice, which not only wastes time but also reduces the intelligent experience. Summary of the Invention
[0004] The purpose of the present invention is to provide an intelligent rice cooker that eliminates manual rice washing to improve the process of fully automated rice cooking.
[0005] To solve the above technical problems, the technical solution adopted by the present invention is: an intelligent rice cooker that eliminates manual rice washing, including a bin body and an inner pot. The bin body is set as a cylindrical main structure, with a cover clamped at the top, and a heating element fixedly arranged inside. It is characterized in that: the bin body is divided into upper, middle, and lower three-layer structures. The top layer is provided with a rice adding channel, and a water injection channel is also provided on one side of the rice adding channel. One side of the middle layer is fixedly provided with a controller, and the controller is electrically connected to a temperature sensor, a pressure sensor, and a humidity sensor. The temperature sensor, pressure sensor, and humidity sensor are fixedly connected to the inner pot. The lower layer is fixedly connected to the heating component. The inner wall of the inner pot is fixedly provided with a receiving ring, and a receiving plate with hydrophobic holes is fixedly arranged at the top of the receiving ring. A rotating motor is fixedly arranged inside the cover, and a connecting rod is tightly connected to the outer wall of the output end of the rotating motor. A drain port communicating with the inner pot is fixedly arranged on one side of the bin body.
[0006] As a further improvement of the present invention, the heating component adopts a dual-mode heating system, with an IH electromagnetic coil at the bottom and a ring-shaped PTC heating sheet fixedly connected to the side wall.
[0007] As a further improvement of the present invention, the inner pot adopts a five-layer composite material, which is, from the outside to the inside: an outer layer of hard alumina, a middle high magnetic conductivity layer, a honeycomb-shaped heat-conducting aluminum layer, a far-infrared ceramic layer, and a food-grade non-stick coating.
[0008] As a further improvement of the present invention, a 3 mm clearance fit is formed between the bottom of the inner container and the IH electromagnetic coil, and the side wall is closely attached to the annular PTC heating sheet.
[0009] As a further improvement of the present invention, a dynamic steam regulating valve is fixedly arranged inside the bin body, and a spring-type pressure balancing device is built in the steam regulating valve.
[0010] As a further improvement of the present invention, the data lines of the temperature sensor, the pressure sensor and the humidity sensor are connected to the controller through an electromagnetic shielding channel.
[0011] Advantages of the present invention: By providing a controller in this new type of appliance, and a rice adding channel is communicated with the upper layer of the bin body, and components such as a drain port and a receiving plate arranged at the bottom side of the bin body facilitate the rice washing operation. Users can remotely connect the rice cooker to a mobile phone and drive and control it through a remote APP, enabling autonomous rice washing, monitoring the cooking situation and the remaining amount of rice, and pre-reserving the cooking time in advance, improving the cooking process, and realizing the intelligence and autonomy of cooking.

[0017] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the following further describes the present application in detail with reference to the accompanying Figures 1-4 drawings and embodiments. It should be understood that the embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0018] The invention provides an intelligent rice cooker without manual rice washing, comprising a warehouse body 1 and an inner pot 2, wherein the warehouse body 1 is arranged as a cylindrical main body structure, a sealing cover 3 is clamped at the top, and a heating element is fixedly arranged inside, and the characteristic is that the warehouse body 1 is divided into an upper layer, a middle layer and a lower layer structure, a rice adding channel 4 is arranged at the top layer, a water injection channel is also arranged at one side of the rice adding channel 4, a controller is fixedly arranged at one side of the middle layer, the controller can be driven by an STM32 single-chip microcomputer, and the controller is electrically connected with a temperature sensor, a pressure sensor and a humidity sensor, wherein the temperature sensor is arranged as a bottom NTC (accuracy ±0.5°C) + a top infrared temperature measurement, the pressure sensor is a piezoelectric ceramic type with a measuring range of 0-2MPa, and the humidity sensor selects a capacitive temperature sensor (accuracy ±3%RH). The pressure sensor and the humidity sensor are fixedly connected to the inner tank 2, and the lower layer is fixedly connected to the heating element. A receiving ring 5 is fixedly provided on the inner wall of the inner tank 2, and a receiving plate 6 with a hydrophobic hole is fixedly provided on the top of the receiving ring 5. A rotating motor is fixedly provided inside the cover, and a connecting rod 7 is fastened to the outer wall of the output end of the rotating motor. A drainage outlet connected to the inner tank is fixedly provided on one side of the storage body 1.
[0019] In the present invention, the heating element adopts a dual-mode heating system, with a 1300W IH electromagnetic coil (26cm in diameter, 32 turns of spiral winding) at the bottom, and a 600W annular PTC heating sheet fixedly connected to the side wall, covering 60% of the height of the inner tank. The dual heating unit is coupled to the inner tank through a thermally conductive silicone pad and is time-sharingly controlled by the main control module of the controller.
[0020] In the present invention, the inner pot 2 is made of five layers of composite material, which are: outer hard anodized aluminum, middle high magnetic permeability layer, honeycomb thermal conductive aluminum, far infrared ceramic layer, and food-grade non-stick coating. The bottom of the inner pot 2 forms a 3mm gap with the IH electromagnetic coil 8, and the side wall is tightly fitted with the annular PTC heating plate. The heat transfer efficiency is enhanced and the structural strength is improved.
[0021] In the present invention, a dynamic steam regulating valve is fixedly arranged inside the warehouse body 1. The dynamic steam regulating valve is a double-cavity silicone structure, with a temperature resistance of 250°C, and the steam regulating valve has a built-in spring-type pressure balancing device.
[0022] In the present invention, the data lines of the temperature sensor, the pressure sensor and the humidity sensor are connected to the controller through an electromagnetic shielding channel, thereby reducing electromagnetic interference during data transmission.
[0023] Example:
[0024] Users can connect to and control the rice cooker through the APP, preset the actual dining time, and adjust cooking parameters via the mobile phone. The user only needs to put rice into the inner pot through the rice feeding channel 4. The system controls the preset water-to-rice ratio and steaming time, injects water and washes the rice inward, so that the rice on the receiving plate 6 of the inner pot 3 is washed. In addition, the rotating motor located in the cover 3 can be started to make the multiple connecting rods 7 at its output end rotate, increasing the rice washing efficiency. Since the inner pot is made of a five-layer composite material, the high magnetic conductivity layer therein optimizes the IH electromagnetic induction efficiency, enabling a heat conversion rate of 92%. The honeycomb structure realizes three-dimensional heat transfer, with a temperature uniformity of ±1.5°C, causing the ceramic layer to generate far-infrared radiation and increasing the starch gelatinization rate by 15%. The power consumption for cooking 3L of rice is only 0.25 kWh (30 minutes at 500W power), saving about 20% energy compared to traditional bottom-heated rice cookers (0.3 - 0.4 kWh).
