Description
Technical field
The present invention relates to household electrical appliance technical field more particularly to a kind of microwave devices with humidification function.
Background technology
Micro-wave oven is the electric appliance cooker heated to food using high-frequency microwave, passes through the radiation effects in high-frequency microwave
The frictional heat that lower food molecule high vibration generates heats food.When micro-wave oven carries out cooking operation, microwave penetration food can be with
It is inside and outside to heat simultaneously, have many advantages, such as that efficient, speed is fast and application is convenient.Therefore, it is wide gradually to become application for micro-wave oven
General domestic electric appliance.
The appearance of micro-wave oven is in rectangular shape, and fire door is arranged in the shell front of cuboid, and control plane is arranged in fire door side
Plate, control panel are equipped with micro-wave oven operation key and display screen.Furnace chamber is formed in shell, the upper surface of furnace chamber and side setting are micro-
The internal component of wave stove mainly has magnetron, waveguide, control circuit device and blender etc..
Magnetron is the heart of micro-wave oven, is microwave electron of the electronics with potential forms positive energy exchange to microwave electromagnetic field
Pipe is the vacuum device for generating high-power high-frequency oscillation energy.The continuous microwave that magnetron generates passes through high-conductive metal material
Waveguide convey and on the food that is radiated in furnace chamber, by make under the radiation effects of high-frequency microwave the food in furnace chamber by
It is hot uniform.
The magnetron of micro-wave oven is made of tube core and magnet two parts.Tube core includes cathode, anode and antenna, and cathode is located at
In the middle part of magnetron, anode is looped around cathode peripheral, and anode is always grounded, and cathode is made to become negative high voltage.Magnet generally use is permanent
Magnet, the high-intensity magnetic field of space formation axial constant between the anode and the cathode.
Cathode generally uses helical heater made of thoriatde-tungsten wire or pure tungsten filament winding, can be promptly after turn-on current heating
Launching electronics.The electronics emitted after cathode heating, High Level DC Voltage is acted between by anode and cathode, to anode movement.Together
When, the thermoelectron of emission of cathode will also be acted on during to anode movement by axial magnetic field.In this way, thermoelectron is in electricity
Make wheel cycloid motion under the action of field force and magnetic field force, and vibrates and generate micro- in the resonant cavity on cathodic anode surface
Wave.Its bundle of lines microwave coupling comes out, and radiation higher-order of oscillation microwave is formed, through on waveguide conveys and is radiated in furnace chamber food
It is heated.
After the energy exchange that oscillating microwave is coupled through antenna, also there is thermoelectron certain energy, these thermoelectrons to beat
On anode, temperature of anode is made to increase, bigger (the energy conversion of energy of electronics more (i.e. electric current is bigger) or electronics that anode is collected
It is lower), temperature of anode is higher.
Very high heat (300 DEG C~400 DEG C) itself is will produce in magnetron work, if temperature is excessively high, magnetic control can be made
Pipe damages.
Therefore, in order to reduce the operating temperature of magnetron, in order to avoid magnetron damages, heat dissipation is set usually on the outside of anode
Piece carries out air blast cooling heat dissipation using fan.
In addition, heater is also separately provided in some micro-wave ovens, the steam generated using heating water increases food in furnace chamber
Humidity promotes the effect of microwave oven heating food.
However, the micro-wave oven of the above-mentioned prior art expends energy again there is the heat for both needing to disperse magnetron generation
For heating water producing water vapor, this there is thermal resource and utilizes unreasonable problem amount.
