Description
Technical Field
The utility model belongs to high-power electromagnetism stove field, concretely relates to heating system of high-power electromagnetism stove.
Background
The high-power induction cooker (also known as a high-power induction cooker, a high-power commercial induction cooker and the like) refers to an induction cooker (cooker) with the power of 3 KW-35 KW; the high-power induction cooker is different from a household induction cooker in power and application range, and the high-power induction cooker is mainly applied to commercial kitchens rather than household kitchens, such as commercial kitchens of restaurants, wine buildings, factories, universities, institutions, troops, enterprises and public institutions, trains, ships and the like in the catering industry. (see Baidu encyclopedia entry high-power induction cooker).
The heating system of the existing high-power induction cooker comprises a coil and a machine core, wherein the machine core mainly comprises a strong current unit and a weak current unit, the strong current unit comprises an IGBT element, a capacitor element and a rectifier bridge element, and the weak current unit mainly comprises a main control integrated circuit board (see CN103582195A a commercial electromagnetic machine core structure).
The heat dissipation mode generally adopts the similar heat dissipation modes such as CN202350127U (electromagnetic big frying stove), CN204478185U (commercial big frying stove), CN206094209U (electromagnetic big frying stove), CN202350122U (electromagnetic small frying stove), CN204478184U (electromagnetic commercial small frying stove), CN203949228U (electromagnetic small frying stove) and CN105066194B (electromagnetic small frying stove with magnetic induction gear).
Namely: the heat dissipation of the coil is usually to arrange a fan at the bottom of the coil to blow air to the coil; the heat dissipation of the core is to arrange a strong electric unit of the core on a heat dissipation plate, and then one or two fans are arranged on the core to blow or exhaust air to the heat dissipation plate; then an exhaust fan is arranged on the furnace wall to extract hot air in the furnace body.
The existing heat dissipation method has the following defects:
1. the coil fan blows air to the periphery of the coil from the bottom of the coil, and hot air passing through the coil is still in the furnace body, so that heat dissipation of the coil is affected.
2. The core and the coil are independent in heat dissipation, independent fans are needed respectively, and at least one fan is needed on the external furnace wall, so that at least three fans are needed for heat dissipation of the whole heating system.
