Description

A kind of intelligent cooking stove of high efficiency and heat radiation
Technical field
The present invention relates to culinary cuisine utensil field, particularly a kind of intelligent cooking stove of realizing high efficiency and heat radiation.
Background technology
Electromagnetism cooker in the prior art; The radiator fan and the air outlet that generally comprise housing, be located at the air inlet of housing, corresponding air inlet are provided with; Be provided with electromagnetism heating spool rest and wiring board in the housing; The heat radiation process of electromagnetism cooker is: heat radiation wind is got in the housing by air inlet, after the relevant heater element heat radiation of heat radiation wind to the electromagnetism cooker, outside air outlet blows out the electromagnetism cooker.Above-mentioned electromagnetism cooker can produce following problem when heat radiation: 1, because the heater element on the wiring board is the object that mainly dispels the heat at present; Wiring board generally is located between the air outlet on air inlet and the housing, yet above-mentioned heat radiation receives the enclosure interior spacial influence bigger, is prone to form the internal heat dissipating dead angle; The part air-flow forms eddy current in the enclosure; Because the employing of suction-type fan can make machine intimate that certain blast is arranged, cause air quantity to run off, heat radiation air quantity utilization rate is low; And the heat radiation wind direction is at random, and radiating effect is poor.With existing electromagnetic stove is example, and air inlet is located at the lower house bottom, air outlet is located at hull outside, and long sink flows circulation passage produces the eddy current and the air quantity losing issue of above-mentioned existence; In addition; The heat radiation wind direction that aerofoil fan in the electromagnetic stove sucks is usually along axial air-out; Most of heat radiation wind by housing bottom entering electromagnetic stove inside can upwards vertically blow along the axial of aerofoil fan; And existing electromagnetic stove inside generally shifts to install wiring board and air inlet in the horizontal direction, and the further loss that this just causes air quantity more causes the cooling-down effect of the heat generating components on the wiring board not obvious.2, when the electromagnetism drum of electromagnetism cooker is the spill drum; When dispelling the heat simultaneously, blow to the wind of spill drum bottom, can produce part drum rapid heat dissipation from single direction for wiring board and electromagnetism drum; And other local generations of drum are dispelled the heat slowly; Even blow less than wind regime, be example with IH meal pot, its spill drum will produce the uneven problem of heat radiation.
Yet no matter be IH meal pot or spill electromagnetic stove, its spill electromagnetism drum can take more space, makes the space up and down of cooking stove strengthen; And the spill electromagnetic stove of employing aerofoil fan; Because the thickness limits of aerofoil fan, the space up and down that can further increase the spill electromagnetic stove makes the thickness of existing spill electromagnetic stove increase; Integral body is comparatively heavy, does not meet the demand of user's lighting.
In addition, for the electromagnetism cooker with end air intake, side air-out, the structure of side air-out causes that easily water gets into electromagnetism cooker inside along the thermovent of side, produces potential safety hazard; In addition, the electromagnetism cooker of thermovent is opened in the side, and it is moulded to destroy product, so this series products has the trend of being eliminated by market gradually.Because the above-mentioned technological deficiency that the electromagnetism cooker exists has influenced the marketing of this series products.
Heat radiation air-out and integrally-built technological deficiency that above-mentioned electromagnetism cooker exists; Not only limited the market scale of this high energy efficiency, oligosaprobic electromagnetism cooker, especially existing market is shown great attention to for security of products, efficiency and lighting and is made existing electromagnetism cooker improve extremely urgent.
Summary of the invention
