Description
Technical field
The present invention relates to micro-wave oven field more particularly to a kind of radiator structures of the micro-wave oven with high cooling efficiency.
Background technique
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.
