Electromagnetic induction rice cooking device capable of uniformly heating

Technical Field

The utility model relates to the technical field of rice cooking devices, in particular to an electromagnetic induction rice cooking device capable of uniformly heating.

Background

The existing rice cooking device is carried out by adopting an electric cooker, the main heating mode of the existing electric cooker is that an internal heating element is heated by electrifying a heating plate at the bottom end, so that the heating plate heats, and then the heating plate conducts heat to an inner pot which is placed on the heating plate and is in direct contact with the heating plate, so that heating is realized, but the heating of the heating plate is firstly carried out in such a mode, so that certain energy loss is generated by the heating plate when current passes through the heating plate when heat is generated, then partial heat loss is generated by the heat on the heating plate when the heat is conducted to the inner pot, the heat conduction efficiency is low, if the existing electromagnetic oven principle is adopted for cooking, the whole magnetic flux is gradually reduced from inside to outside due to the principle problem, the heat generated by the whole inner pot is very uneven, the heat of the middle heat is high, and the heat is low in the outer side, and further may cause unevenness of the cooked degree of the rice cooking, for which we propose an electromagnetic induction rice cooking apparatus of uniform heating.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-3, an electromagnetic induction rice cooking device with uniform heating comprises a shell 1, a control center is fixedly installed outside the shell 1, a thermal sensor 2 is fixedly installed at the bottom end inside the shell 1, a bottom plate 3 is fixedly installed below the inside of the shell 1, a support frame 4 is fixedly installed on the upper surface of the bottom plate 3, a coil 5 is fixedly installed on the support frame 4, an upper placing plate 6 is fixedly installed above the coil 5 inside the shell 1, and the thermal sensor 2 and the coil 5 are electrically connected with the control center.

Wherein, thermal sensor 2 is located the below of coil 5, has seted up slotted hole and position correspondence on bottom plate 3 and the last dish 6 of placing, and thermal sensor 2 aims at the slotted hole position installation, can independently detect the heat of bottom of a boiler simultaneously through every thermal sensor 2 like this to can be better comprehensively transmit the heat distribution of whole bottom of a boiler for control center, and then better control coil 5 carries out the adjustment of pertinence ground power, guarantee the homogeneity of device heating.

The thermal sensor 2 is correspondingly arranged at the vertical position of the central part of the coil 5, so that the thermal sensor 2 can better penetrate through the slot hole to monitor the temperature of the pot bottom in real time, and a control center can be ensured to adjust in time.

The number of the coils 5 is multiple, the coils are uniformly distributed and installed on the upper surface of the bottom plate 3, the diameter of each coil 5 is far smaller than that of the bottom plate 3, so that the power of each coil can be independently controlled by the control center by changing the traditional concentric winding coils, the temperature of each small area can be accurately controlled according to the monitoring result of the thermal sensor 2, the condition that the traditional large coil gradually decreases from inside to outside to cause uneven heating is avoided, and the practicability of the device is embodied.

The working principle is as follows: when the electric heating cooker is used, the starting device is used for placing the inner pot filled with the mixture of rice and water on the upper placing plate 6 in the shell 1, then the coil 5 generates a magnetic field after current is introduced, so that the inner pot starts to generate heat, meanwhile, the heat sensor 2 monitors the temperature of the bottom of the inner pot in real time and transmits signals to the control center, and when the temperatures monitored by the heat sensors 2 are different and deviate from a fixed value, the control center can carry out independent power adjustment on the coil 5 on the heat sensor 2 corresponding to the position deviating from the fixed value, so that the heating uniformity of the whole inner pot is ensured.
