Description
Technical field
The present invention relates to a kind of agitator of micro-wave oven, particularly relate to a kind of can more effective microwave the stirring, improve a kind of microwave stirrer that microwave distributes.
Background technology
Microwave is a kind of high frequency waves, with the velocity transformation of per second 2,400,000,000 times, causes the high-speed motion of hydrone approximately, friction generates heat mutually to make hydrone, to reach purpose, can therefore be applied in the culinary art of a variety of foods simultaneously to heating inside and outside the food to the food heating.
Ventilating hood-type microwave oven (hereinafter to be referred as micro-wave oven) is except having the basic function of utilizing microwave cooked cooking thing, also have and can discharge the flue gas that produces in the gas burning roastor of micro-wave oven bottom to the outside, micro-wave oven is arranged on the wall corresponding to gas-cooker top usually.
As shown in Figure 1, Fig. 1 is the profile schematic diagram of the micro-wave oven in the prior art, and micro-wave oven 1 profile is cuboid, constitutes two sides and an end face by shell 10.Food can be placed in the inside of above-mentioned shell 10, constitutes the culinary art chamber 20 of cooking space.Culinary art chamber 20 is formed by connecting by the bending of a lot of sheet metallic plate, and the front is an opening.Culinary art is equipped with the rotary-tray 22 that can place food in the chamber 20, and this rotary-tray is by independent CD-ROM drive motor driven rotary, so that the food that is placed on the rotary-tray is evenly heated.Simultaneously, the frontal left of opening in culinary art chamber 20 is installed with the fire door 30 that can rotate to a side, rotate fire door 30 and the open front face of culinary art chamber 20 can be closed, thereby microwave is leaked to the outside when preventing to cook.In addition, be provided with electric control chamber 50 on the right side of culinary art chamber 20, the front portion of this electric control chamber, the positive right side of face of promptly above-mentioned microwave oven 1 is an operation panel 40, this operation panel 40 constitutes the positive facial contour of microwave oven 1 with above-mentioned fire door 30.On operation panel 40, be separately installed with the control handle 42 and the operating buttons 44 of the work of operating electronic micro-wave oven, and the display screen 46 that can show the cooking status of the working condition of microwave oven and food.This electric control chamber is the place that the essential electric field part of microwave oven 1 work institute is installed, and magnetron, the high-tension transformer that high voltage source is provided and the capacitor of vibration generation microwave is equipped with in its inside; The microwave that magnetron produces exports through waveguide to waveguide, and through evenly dispersion after the stirring of agitator, microwave is from cavity top heating object to be heated.
For the microwave that micro-wave oven is produced evenly distributes in furnace chamber, an agitator is housed in furnace chamber usually, it is to utilize the air stream that forms in the furnace chamber to drive agitator that some micro-wave ovens are also arranged.Agitator is generally a slice flabellum and back shaft riveted joint, and the driven by motor back shaft rotates, and then drives the purpose that the flabellum rotation reaches stirring.As shown in Figure 2, described agitator 51 is arranged on 20 roofs of culinary art chamber, the installation position of agitator 51 is stamping into groove on 20 roofs of culinary art chamber, this groove constitutes the fan guard 52 of agitator 51, fan guard 52 is provided with fan cover 53, agitator 51 is installed between fan guard 52 and the fan cover 53, and the supporting axis of fan cover 53 is being supported agitator 51.Power output is low, firing rate is slow, frequency difference is big but this agitator microwave skewness when stirring microwave that has only a slice flabellum to constitute can occur, as shown in Figure 3, from the microwave distribution map as can be seen microwave very easily the reflected back magnetron cause shortcomings such as magnetron damage, potential safety hazard appears easily.Through the cooking experimental analysis, the mark that thaws only is 13 minutes, and it is low excessively the edge central temperature that overdoes to occur, and the rate of thawing has only about 60%.
Summary of the invention
Technical problem to be solved by this invention is, overcomes the shortcoming of prior art, provides that a kind of power output is high, firing rate is fast, heating uniformity good and the stable a kind of microwave stirrer structure by force of magnetron.
The technical solution used in the present invention is: a kind of microwave stirrer of micro-wave oven, micro-wave oven comprise shell, culinary art chamber, cavity, electric control chamber and fire door; Be provided with microwave stirrer in the described cavity; Described microwave stirrer comprises first flabellum and second flabellum, and described first flabellum and second flabellum are riveted with back shaft respectively.
The axial distance of described first flabellum and second flabellum can be 20-23mm; Form the stagger angle that pivots between two flabellums and can be 20-35 °.
The axial distance 22.5mm of described first flabellum and second flabellum; Forming the stagger angle that pivots between two flabellums is 30 °
The invention has the beneficial effects as follows: owing to increased a slice flabellum on the agitator back shaft, during agitator work, double-deck flabellum moves simultaneously, two flabellums exist differential seat angle and difference in height, thereby can more effectively stir, improve the microwave distribution, improve the thermal efficiency microwave.

The specific embodiment
As shown in Figure 4, a kind of microwave stirrer of micro-wave oven, micro-wave oven comprise shell, culinary art chamber, cavity, electric control chamber and fire door; Be provided with microwave stirrer in the described cavity; Described microwave stirrer comprises first flabellum 100 and second flabellum 200, and described first flabellum 100 and second flabellum 200 are riveted with back shaft 300 respectively.Axial distance between described first flabellum 100 and second flabellum 200 can be 20-23mm; Form the stagger angle that pivots between two flabellums and can be 20-35 degree angle.Axial distance optimal selection 22.5mm between described first flabellum and second flabellum; Forming the stagger angle optimum that pivots between two flabellums is 30 degree.
As shown in Figure 5; owing to increased a slice flabellum on agitator back shaft 300, i.e. second flabellum 200 is during agitator work; the simultaneously supported axle of double-deck up and down flabellum drives, rotation; adopt two flabellums to be set with differential seat angle and difference in height, thereby can more effectively stir, as shown in Figure 6 microwave; improved the microwave distribution; improve the thermal efficiency, reduced the probability that magnetron is returned in microwave reflection, also protected magnetron simultaneously effectively.Through the cooking experimental analysis, the mark that thaws reaches 23 fens, and the rate of thawing is about 90%.
In like manner, the present invention is not only applicable to ventilating hood-type microwave oven, promptly except having the basic function of utilizing microwave cooked cooking thing, also has micro-wave oven from the flue gas that produces in the gas burning roastor of micro-wave oven bottom to the outside that to discharge, also be applicable to general micro-wave oven, only need adjust during design between height between two flabellums and two flabellums and spend the angle, just can effectively improve microwave and distribute, improve the thermal efficiency, improve the overall performance of micro-wave oven.
It is worthy of note; protection scope of the present invention is not limited to above-mentioned instantiation mode, and according to basic fundamental design of the present invention, those of ordinary skills need not through creative work; the embodiment that can associate all belongs to protection scope of the present invention.
