Abstract
The invention discloses a microwave oven provided with two-layer stirring fans. A first stepper motor controlling uniformity of microwaves and a second stepper motor controlling microwave emissive power are arranged under a soleplate of the microwave oven; a rotating shaft of the second stepper motor passes through the soleplate and drives a driver gear to rotate; the driver gear drives a driven wheel which is meshed with the driver gear to rotate; a rotating shaft which is of a lug boss shape and used for mounting a lower layer of stirring fans which control the microwave emissive power, is formed on the driven wheel,; a through hole is arranged in the center of the driven wheel and the rotating shaft; a rotating shaft of the first stepper motor passes through the through hole; an upper layer of stirring fans which control the uniformity of the microwaves are arranged on the rotating shaft of the first stepper motor. The drive and control structure of the invention is simple, thereby reducing total time of heating up food and increasing utilization rate of electrical energy.
Description
Technical field
The present invention relates to a kind of micro-wave oven, especially have the micro-wave oven of double-layer stirring fan.
Background technology
Generally speaking, micro-wave oven be a kind of high frequency (the about 2450MHz of per second) microwave that utilizes as heating source, carry out the device of cooking food by upsetting the frictional heat that produces of putting in order between the food molecule.This micro-wave oven is divided into substantially: for the gratin to furnace chamber inside equably provides microwave and rotates the rotating disk mode that is placed with gratin; Mode is fanned in the stirring that microwave evenly can be offered furnace chamber inside with utilization.Certainly, can utilize above-mentioned dual mode simultaneously.Fig. 1 is the inside partial structurtes figure that the fan mode is stirred in the utilization of prior art micro-wave oven.This micro-wave oven mainly is to be provided with stirring fan component in the furnace chamber bottom that forms cooking room or top or side spaces.At this moment, be provided with the microwave that provides by not shown magnetron abrim in the space of stirring fan.And the space upside with stirring fan component also is included in when forming the cooking room bottom surface supporting plate 9 that stirring fan component and cooking room inner space can be separated.The stirring fan component of prior art comprises: electric rotating machine 17; Be combined in the stirring fan rotating shaft 20 on the spin motor shaft 17a; Be installed in the stirring fan 15 that stirs fan rotating shaft 20 upper ends; Regulate and stir back shaft 22 and the fixing boss 21 that stirs fan rotating shaft 20 that fan rotating shaft 20 can move up and down the V1 distance vertically.The 5th, the bottom surface of micro-wave oven.
Adopt the micro-wave oven that stirs fan that has of said structure, in heating process, by the distance of change stirring fan with supporting plate 9, the power of control microwave.
But the stirring fan of the micro-wave oven of prior art is owing to have only one to stir fan, can only control the transmitting power of microwave, not only control and move up and down but also control rotating speed if stir fan, referring to Chinese patent 200410001023.0 by one, the driving complexity of motor is prone to fault.
Summary of the invention
Technical problem to be solved by this invention is, a kind of simple in structure, micro-wave oven that has double-layer stirring fan of reducing heat time heating time is provided.
For the technical solution problem, the technical solution used in the present invention is: a kind of micro-wave oven that has double-layer stirring fan is equipped with inhomogeneity first stepper motor of control microwave and second stepper motor of controlling the microwave transmitting power below bottom plate of microwave oven; The rotating shaft of second stepper motor passes base plate, the rotation of drive travelling gear, travelling gear drives the follower rotation of engagement, the rotating shaft of fanning stirs in the lower floor that controls the microwave transmitting power that is used to install that is formed with the boss shape on the follower, there is through hole at center at follower and rotating shaft, the rotating shaft of first stepper motor passes through hole, the inhomogeneity upper strata stirring of control microwave fan is installed on the rotating shaft of first stepper motor, and two sides also are included in will stir when forming the cooking room bottom surface and fan the supporting plate that separates with the cooking room inner space on the space of stirring fan.
Between upper strata stirring fan and lower floor's stirring fan, be provided with the fixture that prevents that the two from swinging up and down.
Described fixture is a U-shaped, stirs fan and lower floor on the upper strata and stirs between the fan, and it is fixing that fan is stirred on upper end and upper strata, and the top that fan stirs in lower floor is closed in the lower end, the axial wobble that fan stirs in restriction lower floor.
The invention has the beneficial effects as follows: the stirring fan that has only adopted rotation mode, two are stirred fan by two stepper motors drives up and down, a control microwave transmitting power, another control microwave uniformity, rotating speed of motor is by the unified control of a control module, driving and control structure are simple, reduce the time of whole heat food, have increased the utilization rate of electric energy.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail:
Shown in Fig. 2,3,4, the present invention has the micro-wave oven of double-layer stirring fan, and the second stepper motor (not shown) of inhomogeneity first stepper motor of control microwave and control microwave transmitting power is installed below bottom plate of microwave oven 30; The rotating shaft 32 of second stepper motor passes base plate 30, drive travelling gear 33 rotations, travelling gear 33 drives follower 34 rotations of engagement, be formed with the rotating shaft 35 that is used to install lower floor's stirring fan 40 of controlling the microwave transmitting power of boss shape on the follower 34, there is through hole 36 at center at follower 34 and rotating shaft 35, the rotating shaft 31 of first stepper motor passes through hole 36, the inhomogeneity upper strata stirring of control microwave fan 41 is installed on the rotating shaft 31 of first stepper motor, and the space upside that stirs fan also is included in will stir when forming the cooking room bottom surface fans the supporting plate (not shown) that separates with the cooking room inner space.Between upper strata stirring fan 41 and lower floor's stirring fan 40, be provided with and prevent the two fixture that swings up and down 42.Fixture 42 is a U-shaped, stirs fan 41 and lower floor on the upper strata and stirs between the fan 40, and upper end and upper strata stirring fan 41 are fixing, and the top that fan 40 stirs in lower floor is closed in the lower end, limits the axial wobble that fan 40 stirs in lower floor.
The present invention has only adopted two to stir fan, because respectively by different step motor control, two rotating speed differences that stir fan, fan 41 control microwave uniformities are stirred on the upper strata, lower floor's stirring fan 40 control microwave transmitting powers, rotating speed of motor is by the unified control of a control module, and driving and control structure are simple, reduce the time of whole heat food, increased the utilization rate of electric energy.
In sum, among the embodiment that content of the present invention is not confined to, the knowledgeable people in the same area can propose other embodiment easily within technological guidance's thought of the present invention, but this embodiment comprises within the scope of the present invention.
