Description

Technical Field

[0001] The utility model relates to the technical field of rice cookers, in particular to a rice cooker with accurate temperature measurement. Background Art

[0002] A rice cooker is a household appliance that uses electric energy to heat water to boiling and maintains the boiling state of the water through constant temperature control technology to cook rice. A rice cooker usually has an inner pot, and there is a heating plate inside the inner pot. The heating plate converts electric energy into heat energy to heat the water to boiling. When the water boils, the rice cooker will automatically adjust the temperature to maintain the boiling state of the water, so that the rice can be evenly heated and cooked. The rice cooker also has a timing function, which can set the cooking time according to the needs of users. The cooked rice has a soft texture and is rich in nutrition. In addition, the rice cooker also has a heat preservation function, which can keep the temperature of the rice after cooking is completed and prevent the rice from getting cold.

[0003] The patent document with the application number CN201920702262.0 discloses a rice cooker, which includes a rice cooker body, a camera and a protection device. The camera and the protection device are arranged inside the rice cooker body, and the protection device covers the camera. Based on the retrieval of the above patent and the combination with the rice cookers in the prior art, it is found that when the rice cooker is in use, it does not have a functional component for temperature detection and adjustability. During the use process, users cannot intuitively understand whether the rice or water in the rice cooker reaches a certain temperature. Especially during the porridge cooking operation, after the porridge boils, foam will be generated, and the foam will quickly increase and overflow the pot body, resulting in a large amount of viscous foam on the inner side of the pot and the inner wall of the pot lid. This will cause a lot of time-consuming and laborious cleaning operations in the follow-up. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a rice cooker with accurate temperature measurement to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A rice cooker with accurate temperature measurement, including a rice cooker body, a pot lid is installed at the upper end of the rice cooker body, a handle is fixedly installed at the upper end of the pot lid, a buffer mechanism and a temperature measurement mechanism are arranged inside the pot lid. The temperature measurement mechanism includes a resistance temperature sensor protection tube, a shielded wire, an insulating sleeve, a measurement end and a connecting rod. A resistance temperature sensor body is fixedly installed inside the pot lid, a resistance temperature sensor protection tube is fixedly installed at the lower end of the pot lid, a shielded wire is installed inside the resistance temperature sensor protection tube, an insulating sleeve is fixedly installed at the lower end of the shielded wire, and a measurement end is fixedly installed at the lower end of the insulating sleeve.

[0006] Optionally, a connecting rod is fixedly installed on the outer wall of the resistance temperature sensor protection tube, and the buffer mechanism includes a machine chamber, a driving motor, a transmission rod, a threaded groove, a screw body, a mounting rod, and a stirring blade.

[0007] Optionally, a machine chamber is fixedly installed in the middle of the pot lid, and a driving motor is fixedly installed inside the machine chamber.

[0008] Optionally, a transmission rod is fixedly installed at the transmission end of the driving motor, and a threaded groove is formed inside the transmission rod.

[0009] Optionally, a screw body is in threaded connection with the inner side of the threaded groove, and a mounting rod is fixedly installed at the lower end of the screw body.

[0010] Optionally, a stirring blade is fixedly installed on the mounting rod, and one end of the connecting rod away from the resistance temperature sensor protection tube is sleeved on the transmission rod.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. In the present utility model, a buffer mechanism is provided. During the porridge cooking process, a large amount of foam will be generated when the porridge liquid boils. Traditional rice cookers lack effective foam control means, resulting in foam overflow, which not only pollutes the kitchen environment but also requires extra time for cleaning. The buffer mechanism effectively reduces the generation and overflow of foam through the intrusion and stirring action of the stirring blade, keeping the rice cooker clean. The stirring action of the stirring blade makes the porridge liquid circulate up and down, enhancing the dissolution and uniformity of the rice, thereby improving the efficiency and taste of porridge cooking. By driving the transmission rod to rotate through the driving motor, and then driving the stirring blade to rotate, the automation control of the stirring process is realized, simplifying the operation of the user and improving the intelligent level of the rice cooker.

[0013] 2. In the present utility model, a temperature measuring mechanism is provided. Traditional rice cookers can usually only measure the overall temperature of the rice cooker and cannot directly measure the temperature of the food materials. This temperature measuring mechanism realizes the accurate measurement of the temperature of the food materials by directly extending the resistance temperature sensor protection tube and the measuring end into the rice or porridge, providing intuitive temperature data for the user, making the cooking process more precisely controllable. The user can adjust the cooking time and firepower according to the temperature data of the food materials to achieve personalized cooking, improving the cooking experience and the taste of the food. By real-time monitoring the temperature of the food materials, measures can be taken in time when the temperature of the food materials is too high to avoid the food materials from being burned or overcooked, improving the safety of cooking.

The shielded wire 502 is used to protect the signal of the resistance temperature sensor from external electromagnetic interference. The insulating sleeve 503 is used to protect the connection part of the resistance temperature sensor to prevent electric leakage and short circuit, and its material and structure need to ensure good insulation and heat resistance. The measurement end 504 is part of the resistance temperature sensor and directly contacts the food to measure the temperature;

[0026] The buffer mechanism 4 includes a machine chamber 401, a drive motor 402, a transmission rod 403, a threaded groove 404, a screw body 405, a mounting rod 406, and a stirring blade 407. The middle of the pot lid 2 is fixedly installed with the machine chamber 401. The inside of the machine chamber 401 is fixedly installed with the drive motor 402. The transmission end of the drive motor 402 is fixedly installed with the transmission rod 403. The inside of the transmission rod 403 is provided with the threaded groove 404. The inner side of the threaded groove 404 is threadedly connected with the screw body 405. The lower end of the screw body 405 is fixedly installed with the mounting rod 406. The stirring blade 407 is fixedly installed on the mounting rod 406. The end of the connecting rod 505 away from the resistance temperature sensor protection tube 501 is sleeved on the transmission rod 403. The drive motor 402 is the power source of the buffer mechanism 4. It drives the stirring blade 407 to stir by rotating the transmission rod 403.

It reduces foam and improves the uniformity of porridge cooking by stirring the porridge body.

[0027] The working principle of the present utility model is as follows: This rice cooker with accurate temperature measurement is additionally provided with a buffer mechanism 4 and a temperature measurement mechanism 5. Before using this rice cooker with accurate temperature measurement, it is necessary to pre-connect the drive motor 402, the resistance temperature sensor, and the resistance temperature sensor protection tube 501 to the power supply and connect them to the control circuit board of the rice cooker body 1. When using this rice cooker with accurate temperature measurement, when using the rice cooker, the temperature measurement mechanism 5 will start automatically, and the resistance temperature sensor body will work. The temperature of ingredients such as rice or porridge is directly detected through the measurement end 504, thereby giving users an intuitive data display. When using the rice cooker to cook porridge, it is necessary to enable the buffer mechanism 4 to perform a buffering operation on the boiling porridge body. When cooking porridge, first rotate the screw body 405, the mounting rod 406, and the stirring blade 407 so that the screw body 405, the mounting rod 406, and the stirring blade 407 move downward as a whole. At this time, cover the pot lid 2, and the stirring blade 407 will penetrate into the porridge body. When the porridge liquid boils, start the drive motor 402 to drive the transmission rod 403 to rotate, and then drive the stirring blade 407 to rotate. By rotating the stirring blade 407, it is possible to avoid a large amount of foam generated by the boiling of the porridge liquid, ensuring the cleanliness of the rice cooker, and at the same time, it can also improve the efficiency of porridge cooking to a certain extent. To sum up, the buffer mechanism 4 adopts a transmission method to drive the stirring blade 407 to stir. When using the rice cooker body 1 to cook porridge, in order to avoid the overflow of foam during porridge cooking, the stirring blade 407 can be used to continuously stir the porridge body, thereby avoiding the generation of foam and reducing the splashing of foam. At the same time, the stirring effect can also make the rice and water blend faster, and the porridge cooking efficiency is higher. The temperature measurement mechanism 5 adopts a resistance temperature sensor body to dive into the rice or porridge to achieve an accurate temperature measurement effect, which is different from the traditional temperature measurement method that cannot directly measure the temperature and can only measure the overall temperature of the rice cooker.
