Abstract
The invention relates to paralleling roasting pipe structure of microwave oven that is formed by two light wave pipe installing in top surface of furnace cavity. The rated voltage parameter of light wave pipe is 220V. Two ends of light wave pipe connect to external power supply of 220V. The structure prolongs useful life of searing pipe and microwave oven and improves reliability.
Description
Technical field
The present invention relates to micro-wave oven, particularly relate to the barbecue tube of micro-wave oven.
Background technology
Micro-wave oven is the household electrical appliance that utilize high-frequency microwave that food is heated and cooks, and produces frictional heat by food molecule high vibration under the radiation effects of high-frequency microwave and cooks operation.Micro-wave oven utilizes microwave penetration food, can inside and outside heating simultaneously, it is fast and use plurality of advantages easily to have an efficient height, speed.Therefore, micro-wave oven progressively becomes widely used domestic electric appliance.
Usually, the outward appearance of micro-wave oven is rectangular shape, forms furnace chamber in the housing.Top, the bottom surface of furnace chamber or side are provided with the internals of micro-wave oven, mainly contain magnetron, waveguide, control circuit device and agitator etc.There is fire door in the housing front of cuboid, and fire door is the passage of placing food and take out food in the furnace chamber in furnace chamber, fire door one side setting operation key.
Magnetron is the heart of micro-wave oven, is a kind of vacuum device, is used to produce the continuous microwave of heat food.The microwave that magnetron produces is carried and is radiated on the food in the furnace chamber by the waveguide of high-conductive metal material.Agitator is made with the metal such as the magnadure plate that conduct electricity very well, intensity is high, just as screw, drive by small machine, in rotatablely moving, constantly change reflection angle to the microwave radiation, thereby improve the distribution of microwave field in the furnace chamber, the food in the furnace chamber is heated evenly.The micro-wave oven that has is not provided with agitator, and the rotating disk of support food is set in furnace chamber bottom, and the food that rotatablely moves with rotating disk also can be subjected to the even heating of microwave radiation.
Fire door has enough mechanical strengths, and that long-term switch uses is still indeformable, non-cracking and microwave leakage do not occur.The observation window of fiberglass is equipped with in fire door central authorities, accompanies intensive pore metallic shield net in the fiberglass, can see cooking status in the stove during use, can make the unlikely leakage of microwave again.
The control circuit device is arranged in the housing; comprise control circuit and respective electric parts thereof; mainly contain power controller, high-tension transformer, high-voltage capacitor, overheat protector, timer, fire door interlocking switch, rotary tray motor (or agitator motor), fan electromotor etc., its function guarantee and control the normal operation of whole micro-wave oven.Computer control type micro-wave oven has diversified control function, can finish multiple work according to previously selected program.Its control function mainly contains: the cooking is regularly selected, cooking power selection, and micro-wave oven regularly starts, temperature control, multiple cooking operation program compatibility, and audible alarm etc.
In recent years, the inner micro-wave oven of barbecue tube of setting up has appearred.Barbecue tube is made of optical wave tube, the light radiation food roasting that utilizes the optical wave tube internal filaments to produce.The micro-wave oven of barbecue tube is set, and its cooking cooking function both can have been utilized the heating using microwave food of magnetron emission more comprehensively, can utilize the light radiation food roasting of optical wave tube again, had more wide market application prospect.
Fig. 1 shows the microwave oven that barbecue tube is set.Fig. 2 is the microwave oven baking tubular construction of prior art.As depicted in figs. 1 and 2, barbecue tube 8 is arranged on the end face of furnace chamber 5, sends the food in the light radiation barbecue furnace chamber 5 bottom rotating disks.Fire door 6 be in furnace chamber 5, place food and in the furnace chamber 5 passage of taking-up food, fire door 6 one side setting operation keys.Observation window 7 by fire door 6 can be seen cooking status in the stove.The side side of furnace chamber 5 is provided with magnetron, transformer and control circuit device.
But the baking pipe for microwave oven 8 of above-mentioned prior art adopts series-mode frame, and it is respectively 110V that the optical wave tube 9 of two series connection distributes voltage.If some optical wave tubes occurs aging, then to distribute voltages be 110V no longer just to two optical wave tubes, but one greater than 110V, and one less than 110V.Thereby optical wave tube is not worked under rated voltage.Like this, further the optical wave tube of acceleration barbecue tube is aging, thereby shortens the life-span of micro-wave oven
Summary of the invention
The present invention be directed to that the existing optical wave tube of prior art micro-wave oven tandem barbecue tube is not worked and the problem of accelerated ageing proposes under rated voltage, its objective is the employing parallel connected roasting pipe structure, two optical wave tubes are worked under rated voltage, increase barbecue tube and use of microwave ovens life-span and reliability.
The parallel connected roasting pipe structure of micro-wave oven involved in the present invention is made of two optical wave tube parallel connections of parallel installation, and the rated voltage parameter of optical wave tube is 220V.Barbecue tube is connected with the external power of 220V by the lead-in wire at optical wave tube two ends.Two optical wave tubes are worked under rated voltage, increased barbecue tube and use of microwave ovens life-span and reliability.

Fig. 1 is provided with the microwave oven figure of barbecue tube for prior art.
Fig. 2 is the micro-wave oven tandem roasting pipe structure figure of prior art.
Fig. 3 is micro-wave oven parallel connected roasting pipe structure figure of the present invention.
Main mark explanation among the figure:
1, housing 2, transformer
3, magnetron 4, waveguide
5, furnace chamber 6, fire door
7, observation window 8, tandem barbecue tube
9, the optical wave tube 10 of tandem barbecue tube, parallel connected roasting pipe
