Description
Technical field
The invention belongs to a kind of microwave baking oven, particularly a kind of direct employing microwave energy carries out the microwave baking oven of baking to food.
Background technology
In the microwave heating technique field, what extensively adopt is that micro-wave oven takes Fast Heating food.Micro-wave oven is to utilize the electromagnetic energy of microwave frequency band to come the home appliances of F&B in the heating cavity; This type of micro-wave oven comprises microwave oven body and is located at the microwave working chamber (resonator) in the body of heater; Fire door, and contain microwave generator, transformer, cooling fan, electric capacity, control circuit (plate) and control panel thereof at interior microwave generation and control device; The principle of its heat food is to send working chamber to after changing electric energy into microwave energy through microwave generator (comprising magnetron, waveguide); In working chamber, set up the microwave field of distribution; When food is in the microwave field; Food can absorb microwave energy and be heated simultaneously inside and outside making food, thereby firing rate is very fast.This mode of heating is for beverages such as heating soups food, milk, not with the food of duricrust, and heating cold dish, cold meal etc., has characteristics such as firing rate is fast, heat time heating time is easy to control; But can not directly be used for baking food, particularly baking poultry, fowl, aquatic product food.
And normal domestic use have a baking function micro-wave oven, and its baking function is through the quartz ampoule that is arranged in inside cavity food to be heated, and has defectives such as speed is slow, energy consumption is high, efficient is low though adopt quartz ampoule to carry out baking to food.At notification number is that CN201032198, name are called that disclosed patented technology promptly belongs to this type of micro-wave oven in the patent documentation of " micro-wave oven that has baking function "; The baking function of such micro-wave oven realizes through " first, second and third heater " be made up of quartz heating-pipe that be installed in the micro-wave oven; Though adopted three heaters in this patent to promote firing rate; So many heating tube makes this micro-wave oven when baking food and have that power consumption is high, efficient is low, because the speed that limits its baking food of mode of heating still more directly adopts microwave energy slow and can not be used for such as barbecue etc. food in enormous quantities being carried out disadvantages such as baking.
Summary of the invention
The objective of the invention is to design a kind of microwave baking oven that is used for baking food; Utilize microwave energy directly food to be carried out baking; With the speed that reaches effective raising baking food, improve baking efficient, energy savings, and be suitable for food in enormous quantities being carried out purposes such as baking such as barbecue etc.
Solution of the present invention is in keeping conventional microwave oven, to contain microwave generator, transformer, cooling fan, high-voltage capacitance, control circuit board and control panel thereof on the basis of interior microwave generation and control device (case); Working chamber (resonator) is changed the semi-cylindrical shape fire door that is made as cylindrical shape working chamber and band micro-wave screening cover, and motor and rotating disk are set, grill is set on rotating disk in the working chamber bottom; Simultaneously microwave take place and the microwave output (waveguide) of control cabinet mouthful and cylindrical shape working chamber between establish one prevent water vapour and oil droplet splash get into that microwave takes place and control device in ripple division board thoroughly; And microwave baking oven fire door still adopts traditional open and close formula structure around the rotation of door hinge, through knocker fire door and body of heater is locked to prevent microwave leakage during work; Because baking poultry, bird, aquatic product food can produce oil droplet and splash, therefore adopt oily dirt free and material nontoxic, high stability to carry out coating and handle at the working chamber inwall, make that the microwave baking oven is easy to clean after use, handle; Microwave takes place and control device adopts still that traditional approach and body of heater fasteningly fuse, its waveguide mouth is connected with the body of heater working chamber to import microwave to working chamber through passing through the ripple division board, operates, can control panel be located at the top of microwave generation and control device for ease; The present invention promptly realizes its goal of the invention with this.Therefore; Microwave baking oven of the present invention comprises that the microwave that contains microwave generator, transformer, cooling fan, high-voltage capacitance, control circuit board and control panel thereof takes place and control device (case); Body of heater and be located at the working chamber (resonator) in the body of heater and be located at the steam vent on the body of heater; Be located at waterproof and oily ripple division board thoroughly between microwave generation and control device and the working chamber; The fire door body of band micro-wave screening cover, key are that the working chamber in the body of heater is that the fire door of cylindrical shape working chamber, band micro-wave screening cover is a semi-cylindrical shape fire door, also is provided with the coating of an oily dirt free at the inner surface of cylindrical shape working chamber and semi-cylindrical shape fire door; And also be provided with in working chamber bottom motor and with motor output shaft link into an integrated entity can (with motor) unidirectional rotation rotating disk, on rotating disk, also be provided with the grill of a band central shaft; Microwave generation and control device are fastened and connected with body of heater, microwave takes place and the waveguide mouth of control device then is communicated with working chamber through passing through the ripple division board; Semi-cylindrical shape fire door body still is connected with body of heater through the door hinge turnably, and grill then is connected with rotating disk is detachable through its central shaft.
For easy to operate, the control panel in microwave generation and the control device is located at the top of this device.And the coating of said oily dirt free is that polytetrafluorethylecoatings coatings or teflon coating, coating layer thickness are 0.15-0.2mm.The rotating disk of said unidirectional rotation, its rotating speed are 6-12 rev/min.
The present invention directly adopts microwave energy that food is carried out baking, has improved the speed and the baking efficient of baking food effectively, has practiced thrift the energy, and is suitable for such as barbecue etc. food in enormous quantities being carried out characteristics such as baking.The present invention is used for baking potato class and poultry, fowl, aquatic product food required time only needs 2-12 minute, can than background technology shorten the baking time about 50% and the food baking even; Poultry, bird food are baked more driedly, and the surface is brown and crisp, and mouthfeel is better.
