Micro-wave oven is that high-frequency microwave is generated using magnetron, and high-frequency microwave, which is transmitted in microwave cavity body, adds food
Heat has many advantages, such as that heating is fast, easy to use, deep to be liked by the people of the world.
The microwave transfer efficiency of magnetron is generally 70% or so, remaining 30% or so power becomes heat when work
Amount, dissipates on magnetron, because power is big, temperature rise is higher, so being all provided with radiator fan in micro-wave oven, carries out to magnetron
Heat dissipation, to prevent magnetron from crossing cause thermal damage.
In the micro-wave oven of traditional structure, electronics storehouse generally is set on the right side of cabinet, magnetron, height are installed in electronics storehouse
The electronic components such as voltage capacitance, transformer, control panel, under normal circumstances, control panel are located at the front in electronics storehouse, and magnetron is located at
Middle part, radiator fan are located at tail portion, i.e. radiator fan is erected on cabinet tail-hood, and the wind that fan sucks in first blows to magnetron,
Control panel is blowed to again.
There are the following problems for above-mentioned traditional structure:
One, the wind that fan is blown into is more dispersed, and only in some wind to magnetron, radiating efficiency is not high；
Two, after in first of wind to magnetron, by the heat of magnetron towards the side of control panel or other electronic components
To being discharged into, first of wind will become hotter second wind after magnetron, hotter second wind be unfavorable for control panel or
The heat dissipation of other electronic components (such as frequency converter), radiating efficiency are low.
Therefore, it is necessary to be further improved.
Summary of the invention
The purpose of the present invention be intended to provide it is a kind of it is simple and reasonable, have excellent performance, be easy to use, radiating efficiency is high, system
The radiator structure of realization at low cost, easy to produce, easy and safe and reliable micro-wave oven is made, to overcome deficiency in the prior art
Place.
By a kind of radiator structure of micro-wave oven of this purpose design, the micro-wave oven includes cabinet, and cabinet is by liner and position

One end that wind scooper is connect with blower tray is big air inlet, and the other end that the first wind scooper is connect with cooling fin is small outlet air
Mouthful.
The intermediate fixed bracket is laterally setting, and liner is located at intermediate support bracket fastened front side；The tail portion of shell is arranged
There is tail-hood, the first electronics position in storehouse is between the fixed bracket in centre and tail-hood.
The side of the shell is provided with side cover, and opening is provided on side cover, is provided with air inlet cover in opening；It is described into
Wind mesh is arranged on air inlet cover；The outlet air mesh is arranged on tail-hood.
The inside air duct of second wind scooper is arc-shaped and its air inlet cover is set on a heat sink, and air outlet is located at
On outlet air mesh, the wind that side cover is introduced is blown out by the second wind scooper from tail-hood.
The periphery of the electronic component is provided with outer cover, and the air inlet and air inlet mesh of outer cover are interconnected, outer cover
The air inlet of air outlet and radiator fan is interconnected.
The support bracket fastened front side in centre is additionally provided with the second electronics storehouse, and the second electronics position in storehouse is in the side of liner, and
Two electronics storehouse accommodated insides have control circuit board；The fixed bracket in centre is Openworks shape, between the first electronics storehouse and the second electronics storehouse
It is interconnected by the fixed bracket in centre.
The control circuit board is at least electricly connected with radiator fan, electronic component, magnetron respectively.
The electronic component is at least frequency converter；The outer cover is at least frequency converter housing, frequency converter housing setting
In the periphery of frequency converter.

Two wind scoopers are fixedly connected with the fixed bracket in tail portion respectively；The tail-hood is fixed at shell by the fixed bracket in tail portion
Tail portion.
By the improvement of above structure the middle position inside the first electronics storehouse is arranged in, together in radiator fan by the present invention
When the air inlet side of radiator fan is provided with electronic component, the air outlet side of radiator fan is provided with magnetron, dissipates
The natural wind that Hot-air fan sucks in first passes through electronic component, thus can radiate well to electronic component, simultaneously
Again because the calorific value very little of electronic component, the temperature of the second wind after electronic component is also very low, second
Road wind then passes through the first wind scooper concentration and blows on the cooling fin of magnetron, and second wind blows for the air outlet of radiator fan
Wind out, air quantity is big, can realize good heat dissipation effect to magnetron, and wind is most afterwards through the second wind scooper from tail-hood after heat dissipation
Outlet air mesh blowout.
Micro-wave oven, using the cooperation of outer cover, the first wind scooper and the second wind scooper, can make outside cabinet when radiating work
The wind concentration that boundary sucks in is blown on electronic component and magnetron, can be effectively improved the radiating efficiency of micro-wave oven, be dissipated simultaneously
