Structure of machine core of commercial induction cooker

Abstract

The invention discloses a structure of a machine core of a commercial induction cooker. The structure of the machine core of the commercial induction cooker comprises a machine box and a coil panel, wherein the machine box is flat, a control circuit board, a circuit board radiator, a direct current fan and a turbofan are distributed on a base plate of the machine box, air inlets under the corresponding direct current fan and the turbofan are formed in the base plate, an oil smoke filtering net is arranged on each air inlet, an air feeding port of the turbofan faces the circuit board radiator, and the coil panel is located above the direct current fan. The structure of the machine core of the commercial induction cooker adopts a novel lower absorption side exhaust type machine box heat dissipation structure, the inner structure is more reasonable and compact, the oil smoke filtering nets are arranged on the air inlets of the machine box and can filter out large-particle impurities, oil smoke prevention of the machine core is facilitated, and the influence on circuit devices of products from foreign matter such as cockroaches and insects under the environment of a commercial kitchen is effectively prevented.

Description

technical field [0001] The invention relates to an electromagnetic cooker, and more specifically relates to a structure of a commercial electromagnetic cooker core. Background technique [0002] The core (that is, the electrical control system) of the traditional commercial induction cooker uses a pcb plug-in circuit board. The strong current part and the weak current part are on the same circuit board. Since the strong current part interferes greatly with the circuit control and driving signals, Therefore the control performance that adopts movement is relatively poor, and control signal is unstable, is a technical problem that needs to solve in the present induction cooker line. [0003] Moreover, the heat dissipation structure in the core of the existing commercial induction cooker is open, because the electronic components on the pcb circuit board are in the form of plug-ins, and the heat generated by it cannot be directly taken away by the radiator through the radiator ...

AI Technical Summary

Problems solved by technology

[0002] The core (that is, the electrical control system) of the traditional commercial induction cooker uses a pcb plug-in circuit board. The strong current part and the weak current part are on the same circuit board. Since the strong current part interferes greatly with the circuit control and driving signals, Therefore, the control performance of the core is poor, and the control signal is unstable, which is a technical problem that needs to be solved in the current induction cooker industry.

[0003] Moreover, the heat dissipation structure in the core of the existing commercial induction cooker is open, because the electronic components on the pcb circuit board are in the form of plug-ins, and the heat generated by it cannot be directly taken away by the radiator through the radiator When designing the movement, it is necessary to consider how to design heat dissipation for some large heating elements. Usually, the fan blows cold air to the large heating elements to dissipate heat, so the circuit structure cannot be completely sealed.

Commercial induction cookers are often used in a high oil fume, high temperature and high humidity environment, causing moisture and foreign matter to damage the core components and circuits

Long-term use will easily cause a large amount of solidified oily smoke and hardening to accumulate in the movement, resulting in poor heat dissipation, and long-term use will cause equipment failure

In view of the great influence of kitchen fume on the corrosion of circuit boards, 40% of after-sales maintenance in the industry is caused by this
