Description
Technical field
The present invention relates to a kind of electromagnetic oven heat radiation structure, be meant a kind of straight-through air duct type forced heat radiation structure especially.
Background technology
Electromagnetic oven is that the principle of utilizing electromagnetism drum electromagnetic induction to produce eddy current realizes pan is heated.In use and since the heating of electromagnetism drum and pan by ceramic panel to electromagnetic oven internal radiation heat, cause electromagnetic oven inside under high relatively temperature, to work, make the operating mode of inner components and parts relatively poor.For this reason, heat radiation is the major issue that the electromagnetic oven heat radiation overview faces.Existing traditional heat-dissipating mode is air-cooled heat radiation, is about to aerofoil fan and forces air discharging and radiating with the parallel installation of electromagnetic oven lower cover.Because aerofoil fan is by the characteristic to air-out, promptly wind direction directly towards loam cake or panel or directly outside exhausting, because of the bend windage is big, causes inefficiency and follows bigger noise, and radiating effect is poor naturally.No. 200810194415.1 disclosed radiator structures of patent application of China are exactly one of representative of traditional approach; No. 200620011547.2 patents of China then try hard to remedy the deficiency of traditional structure, attempt on the basis that does not change traditional basic structure, gimmick with correction or patch installing (as add guide vane in the air channel) is dealt with problems, though can improve heat-sinking capability thus, not produce major transformation on the thinking He on the structure.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, processing and assembling easily, the tube-axial fan radiator structure that radiating efficiency is high.
Designed a kind of electromagnetic oven heat radiation structure according to above-mentioned purpose, be installed on the chassis of electromagnetic oven lower cover formation, comprised lower cover, covered the through hole that has the installation fan down, described fan is an aerofoil fan, and coaxial line is provided with the electromagnetism drum above this fan.The crystallite panel that pan is shelved in this electromagnetism drum and top is coaxial line also, and the crystallite panel is arranged on and is higher than on the boss that the electromagnetic oven boiler face constitutes the kitchen range top and is embedded on the upper surface of this boss.Described boss is and the hardware of furnace panel consubstantiality, offers air outlet equably on the sidewall of this boss.It between the installation through hole of described fan and electromagnetism drum and the boss air channel that is toroidal.Described air outlet is the duct type air outlet, is the interior low, outer low, middle high arc of waterproof.
The present invention compared with prior art changes traditional air chute by laterally becoming vertically, has shortened the stroke of wind greatly, has improved forced heat radiation efficient, has simplified complete machine structure, and assembling is easy, maintenance is convenient, is specially adapted to the high-power electromagnetic oven that power is higher than 2.5kw.
Description of drawings
The specific embodiment
Purport of the present invention provides a kind of electromagnetic oven heat radiation structure that changes traditional horizontal air channel parallel with the electromagnetic oven lower cover for the vertical air channel vertical with the electromagnetic oven lower cover, shorten air channel length significantly and do not have bend, the windage that the air channel is produced drops to minimum, closely directly blow to the electromagnetism drum by axial flow wind, by direct forced convertion heat radiation, make the radiating efficiency of fan reach ultimate attainment.Because traditional electromagnetic oven, is pursued the ultra-thin trend and inevitable that becomes based on the small-sized stove less than 2.5kw, so the air channel also just can only be a horizontally set.And from the demand of environmental protection and culinary art, the electromagnetic oven high-power is an important option, the high-power electromagnetic oven that is higher than 2.5kw is the requirement of satisfying power and heat radiation, the increase of thickness is inevitable, at this moment also being limited to traditional horizontal air channel design concept and making in the self-locking trick undoubtedly and self sink among the yoke, is that also just when the water comes, a channel is formed in vertical air channel so utilize the thickness of high-power electromagnetic oven to change horizontal air channel.The invention will be further described below in conjunction with accompanying drawing.
Accompanying drawing discloses a kind of basic design scheme of electromagnetic oven heat radiation structure.Diagram, with electromagnetic oven lower cover 1 is the chassis, covering the through hole that has installation fan 2 down, described fan is an aerofoil fan, be respectively arranged with electromagnetism drum 3 and the crystallite panel 6 that is used to support pan 7 in the coaxial line mode above this fan, described crystallite panel is arranged on the boss 8 that is higher than the electromagnetic oven boiler face 4 formation kitchens range top and is embedded on the upper surface of this boss.This is of the present inventionly will put the place, and promptly fan is to the direct through type air flue 5 of electromagnetism drum and microcrystal glass plate.This air channel can be made as enclosed according to the actual design demand, and at this moment the device of other need forced heat radiation such as driving element IGBT etc. can utilize other radiator structure arranged side by side or mode to dispel the heat; This air channel also can be designed to open type or semi-open-type, at this moment to contain face bigger in the air channel, need to use more powerful fan (from improving the angle of radiating efficiency, other device that needs forced heat radiation such as IGBT is not in this air channel generally speaking, and this air channel mostly is drum and the heat radiation of crystallite plate is special-purpose).
Being semi-open-type or semi-enclosed air channel shown in the figure, is the example explanation that makes an explanation to scheme below.So-called air channel, it is the fan of coaxial line, electromagnetism drum and crystallite panel are co-located in the same passage, this passage lower end is that fan and fan thereof are installed through hole, the upper end is for being shelved on the electromagnetism drum in the passage and the crystallite panel of sealing " crossing " with its support, be the following little big toroidal air channel of, " wall " that sidewall is formed for other components and parts, from the angle that economizes on resources, open type or semi-open-type air channel are more conducive to fully utilize and can not increase the burden of fan, and radiating efficiency is close with closed air channel, also save supporting parts, optimized structure.In order to realize good heat radiation, it is to have necessary ventilative gap between the line of drum and line that the electromagnetism drum can adopt sparse mode coiled; At this moment, the electromagnetism drum is on the boiler face plane substantially, and the gap between electromagnetism drum and crystallite panel is the passage to air outlet 9 wind-guidings in fact.
Described air outlet is arranged on the sidewall of the boss that constitutes the kitchen range top and protrude from boiler face, also is the extension in air channel, and air outlet should evenly distribute.In order to prevent that the ponding on the boiler face is splashed into, air outlet also is a pipe design, and is the low bow-shaped structural in middle high two.This boss is metal or engineering plastic material, because of the certain thickness of needs, though can disposablely be shaped when adopting plastic cement, but require too high to mould, the mould volume is also big, no matter so metal material or plastic cement material all suitable with boss as a separate part, after two parts (81,82) are processed respectively up and down, involute (see figure 3).
Fig. 4 has illustrated the speed adjustable fan of the used fan of the present invention for being controlled by devices such as sensors, can further save energy and reduce the cost comprehensive benefit height such as environmental protection with this.
