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 called 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.
3. The coil and the movement are independent modules and need to be independently installed.
The radiating mutual influence of simplifying heat radiation structure, reducing fan quantity, reducing coil and core is surrounded, heat radiation efficiency is promoted, still there is following heat dissipation mode among the prior art:

2. Heat dissipation methods as disclosed in CN205227431U (three-phase high-power electromagnetic oven heat dissipation device): it is through the wind channel intercommunication with core and coil, then a fan of wind channel installation between core and coil, and cold wind passes through the core earlier and passes through the coil again, and this structure has reduced fan quantity, but can influence the radiating efficiency of coil to its whole structure heat radiation structure installation is also more complicated.
3. Such as the heat dissipation method disclosed by CN201335429Y (integrated high-power commercial induction cooker): it is similar with CN 205227431U's radiating mode, and it is through setting up the fan between core and coil, and cold wind dispels the heat to the core in proper order then blows to the coil and dispel the heat to the coil, and the difference is that it is through hoisting the core in the coil bottom, makes core and coil form a whole, and this structure not only the radiating efficiency is not high, and the core is heavier moreover.
In addition, there are also some high-power induction cookers, such as: CN204478196U (a commercial electromagnetism stove heat radiation structure), CN202032633U (a two heat dissipation channel embedded electromagnetism stove), CN201606924U (integral type electromagnetism stove module), CN201721019054 (the heat dissipation mechanism of cooking utensil), its majority is desk-top or embedded electromagnetism stove, this kind of electromagnetism stove is for the big stove or the small stove of frying of cabinet type, the power is less relatively, its radiating mode is more similar with the radiating mode of domestic electromagnetism stove, fan set up on the furnace body to coil and power component whole blow or convulsions can, there is great difference with the radiating mode of the big stove or the small stove of frying of cabinet type.
