Description
Technical field
The utility model belongs to small household appliances field, kitchen, is specifically related to a kind of IH electric-heating cooking utensil.
Background technology
IH electric-heating cooking utensil (letting the direct electric-heating cooking utensil of heating of inner bag of the inside through electromagnetic induction heating technology) belongs to kitchen small household appliances industry like IH electric cooker and IH pressure cooker; Have advantages such as heating is fast, heat transfer is even, a kind of health life style easily is provided.The IH electric cooker adopts the electromagnetic induction principle heating, and it utilizes high frequency electric to pass through coil and produces magnetic field, when the magnetic line of force in the magnetic field is bottom the irony pan, can produce countless eddy current, and eddy current makes pot body heating at a high speed voluntarily itself, food in the heating kettle.According to the magnetic field heating principle, IH electric cooker circuit design has fin and fan, and IGPT and coil panel are dispelled the heat, and therefore needs a cover rational air channel design.
Present technology adopts fan directly to dispel backing, does not effectively control wind direction, and the path of wind is disorderly and unsystematic, and following shortcoming is arranged:
1, components and parts moisture-sensitive: because the path of wind does not have effective control, generation freezed when hot and cold wind passed through components and parts, formed droplet and caused the components and parts on the pcb board to make moist or short circuit, caused device failure, influenced interlock circuit simultaneously and produced fault.At subzero 20 degree of cold conditions, situation is more serious.
2, heat radiation is uneven: the path of wind direction and wind is disorderly and unsystematic, causes cold wind to be difficult for coming in, and hot blast is difficult for from the inner discharge of pot body, and the meal inner local temperature of stewing is too high.
3, electric cooker shortening in service life: because the air channel design is bad, external dust is come in fan, and is of long duration, and a large amount of dusts of electronic devices and components adhere to the lost of life.
The utility model content
The purpose of the utility model is to overcome above-mentioned shortcoming, realizes that the protection against the tide of IH electric cooker components and parts is damp proof, and the internal circulation system of mediation IH electric cooker gas reduces the electronic devices and components dust and adheres to, and prolongs electric cooker service life.
For realizing that the technical scheme that the utility model adopted is:
A kind of IH electric-heating cooking utensil; Comprise electronic devices and components and heat dissipation wind channel on radiator fan, fin, IGPT, coil panel, the wiring board; Fin and IGPT are close to; The air outlet of radiator fan is aimed at fin and IGPT, and said radiator fan and electronic devices and components are provided with in order to the wind that stops radiator fan and mark to the wind-guiding tongue of electronic devices and components.
The utility model provides a kind of rational heat dissipation wind channel; Said heat dissipation wind channel comprises first ducting assembly; First ducting assembly comprises wind guide strip, wind-guiding tongue mark and enclosure wall; Wind guide strip is installed in the air flow outlet of fan, wind is gathered blow to fin, and enclosure wall surrounds fin and only stays an outside air outlet; Wind-guiding tongue mark is installed between the components and parts on fin and the pcb board fin and components and parts is separated, and wind-guiding tongue mark has the wind-guiding face of wind direction away from pcb board components and parts one side guiding.
Said heat dissipation wind channel comprises that also an obstruct blows to the second distinguished and admirable ducting assembly of pcb board back, and second ducting assembly is the back that tabular is installed in pcb board.
Said IH electric-heating cooking utensil is IH electric cooker or IH pressure cooker.
When using the utility model, wind blows into from fan, and after the wind guide strip guiding, wind is gathered and blowed to fin, can only go out from the target air outlet through the wind of fin.Lead down in the index of wind-guiding tongue from the wind that the target air outlet comes out, away from the components and parts of pcb board.Second ducting assembly that is installed in the pcb board back makes wind away from the PCB back.
Compare prior art, the beneficial effect of the utility model is:
1. the wind-guiding tongue of the utility model mark will guide outside the wind direction that fan blows out, and make wind away from the pcb board components and parts, can avoid with fan bring into the dust that comes with the passing of time with electronic devices and components dirty with receive dirt, influence service behaviour.
2.IH the electrical equipment influence of attitude and clammy environment of can not making moist in the electric-heating cooking utensil can have the running environment of drying, cleaning, increases the service life.
3.IH the internal circulation system of gas is unobstructed in the electric-heating cooking utensil.
