Abstract

The utility model discloses an improved induction cooker, a circuit board and a coil panel are arranged in a main body of the induction cooker, wherein the coil panel is positioned at the upper end of the circuit board to form a double-layer structure, and a heat insulation aluminum plate is arranged in the middle of the coil panel; two cooling fans which blow air to the circuit board and the coil panel respectively are arranged in the electromagnetic oven main body. Because the circuit board and the coil panel form a double-layer structure, the heat emitted by the coil panel in the working process can be absorbed by the heat-insulating aluminum plate to a large extent, and the heat transferred to the circuit board is greatly reduced; in addition, two cooling fans are adopted to respectively blow air to the circuit board and the coil panel, so that the heat of the circuit board is reduced, and the high power of the induction cooker is facilitated. In addition, the concave coil panel is adopted, the cooker has the advantages of large heating area and uniform heating, can be suitable for various cookers such as pans, convex-bottom pans and the like, and thoroughly solves the problems of insufficient firepower and nonuniform heating when the induction cooker is used for cooking.

Description

Improved Induction Cooker

Technical field:

The utility model relates to the technical field of household appliances, in particular to the technical field of electromagnetic ovens.

Background technique:

Induction cooker is one of household electrical appliances common to people, and existing induction cooker is a single-layer type, and the distance between the circuit board and the coil disc in the main body is very close without isolation. The induction cooker with this structure cannot achieve higher power. The reason is that: during the working process of the induction cooker, the heat from the coil disk will be directly transferred to the circuit board; Poor, these factors are likely to cause the circuit board to fail to work properly due to excessive temperature.

In addition, most of the existing induction cooker coils are flat-bottomed or slightly concave, the heat generated during work is uneven, the area is small, the coil plate generates high heat, and the requirements for the material of the pot are high, and it is different from the common pots on the market. The compatibility is poor, and the type is relatively single. It can only be applied to flat soup pots, and the heating range is concentrated on the bottom of the pot, which is easy to burn the pot and the cooked food tastes not delicious.

Utility model content:

The purpose of this utility model is to provide an improved induction cooker aimed at the deficiencies of the prior art, which can effectively reduce the temperature of the circuit board, so that it will not work normally due to excessive temperature, thereby facilitating the operation of the induction cooker. High power. In addition, it also has the characteristics of large and uniform heating area for the pot, and can be applied to various pots.

In order to achieve the above object, the utility model comprises a main body of an induction cooker, a circuit board and a coil disk are arranged inside the main body of the induction cooker, wherein the coil disk is located on the top of the circuit board to form a double-layer structure, and an insulating aluminum plate is arranged in the middle; the main body of the induction cooker There are two cooling fans inside which blow air to the circuit board and the coil disk respectively.

The two cooling fans are all located at the lower end of the main body of the induction cooker, and the air outlet of one of the cooling fans directly faces the circuit board, and the air blown from the air outlet of the other cooling fan is guided to the coil disk through the air guide device on the heat-insulating aluminum plate.

The coil disk is concave as a whole and is pot-shaped, and the magnetic strip slots on the back are hollow in two sections, and are evenly distributed around the circumference, and the rest are hollow; the coil is located at the upper end of the magnetic strip slot and the front of the coil disk. .

The beneficial effect of the utility model is that: the circuit board and the coil disc form a double-layer structure, and the heat emitted by the coil disc during the working process can be absorbed by the heat-insulating aluminum plate to a considerable extent, and the heat transferred to the circuit board is greatly reduced; secondly, it adopts Two cooling fans are used to blow air to the circuit board and the coil disk respectively, which is also conducive to reducing the heat of the circuit board, thereby facilitating the increase of the power of the induction cooker. In addition, it adopts a concave coil plate, which also has the advantages of large heating area and uniform heating for the pot. It can be applied to various pots, such as pans, convex bottom pots, etc., completely solving the lack of firepower when cooking on the induction cooker And the problem of uneven heating.
