Description

Technical Field

[0001] The utility model relates to the technical field of cooking utensils, in particular to an ultra-long air-spaced electromagnetic heating device. Background Art

[0002] An electromagnetic heating device is a device that converts electrical energy into thermal energy using the principle of electromagnetic induction. It generates an alternating magnetic field by passing alternating current through the heating coil. When this magnetic field passes through the metal, it generates eddy currents inside it. It is the eddy electric field that drives the free electrons inside it to move and generate heat, thereby converting electrical energy into thermal energy, and then heating the food in the container. Existing induction cookers usually need to be used with iron or special stainless steel pots with good magnetic conductivity. When using, the pot needs to be placed in the middle position on the induction cooker panel to obtain the best heating effect. If the pot is not accurately placed in the center of the induction cooker panel, the heating efficiency will be compromised. At the same time, the bottom of the pot is in direct contact with the induction cooker panel, and the induction cooker panel needs to be resistant to high temperature and impact.

[0003] After searching, the existing patent (publication number: CN211011504U) discloses an "induction cooker, comprising a bottom shell (100) and an upper cover (200) connected to the bottom shell (100), a receiving cavity is formed between the bottom shell (100) and the upper cover (200), a circuit board (400), a heat dissipation fan (500) and a coil disk (600) are arranged in the receiving cavity, and a mounting plate for mounting the circuit board (400) and the heat dissipation fan (500) is arranged in the receiving cavity. The bracket (300) and the coil disk (600) are located above the mounting bracket (300). The mounting bracket (300) is provided with an escape area (31). The escape area (31) is used to escape the connecting piece between the bottom shell (100) and the upper cover (200), and / or to escape the connecting piece between the coil disk (600) and the bottom shell (100). The embodiment of the utility model provides an induction cooker, which can solve the problems of complex assembly and low assembly efficiency of the induction cooker housing assembly in the prior art.

[0004] In the process of realizing the present application, the inventor discovered that the prior art has the following problems: Although the above-mentioned comparative patent provides an induction cooker with improved assembly efficiency by setting a accommodating cavity and an avoidance area, it still requires the use of special cookware made of iron or with good magnetic conductivity and is placed directly on the induction cooker panel. It cannot avoid the loss or damage caused by friction or impact between the bottom of the cooker and the induction cooker panel, thereby affecting the service life of the induction cooker panel. Therefore, those skilled in the art have provided an ultra-long air-spaced electromagnetic heating device to solve the problems raised in the above-mentioned background technology.

The pot cover effectively improves the heating, heat preservation and cooking efficiency, while reducing water evaporation and locking the aroma and nutrition of food. The insulation sleeve effectively prevents users from being scalded when moving or using the stone pot, while reducing heat loss to a certain extent to improve cooking efficiency.
