Abstract
The present invention discloses a control method for a fan of a microwave oven. The control methods comprises the following steps: in the first step, whether a heater-type cooking mode or a magnetic-controlled pipe cooking mode or not is judged; in the second step, the fan is automatically started in the heater-type cooking mode; in the third step, if the fan is determined to drive in the magnetic-controlled pipe cooking mode, the fan is started to rotate. The control method has the advantages that firstly, in the microwave oven which can generate microwaves and in which a heater is arranged, only one fan is needed; so that the control method can lower the fabrication cost and decrease component amount; secondly, the microwaves are uniformly dispersed in a cooking chamber of the microwave oven by driving the fan in a microwave cooking mode, so that the control method can improve the cooking performance. Due to the advantages, the purchasing capacity of the microwave oven is enhanced.
Description
Technical field
The present invention relates to a kind of micro-wave oven fan, relate to a kind of fan that utilizes furtherly and give cooking in microwave oven the indoor control method that the fan for microwave oven of microwave is provided equably.
Background technology
Traditional micro-wave oven has been installed magnetron 12 in a side of micro-wave oven sidewall as shown in Figure 1.And, in order to make the microwave that disperses to come out from magnetron 12, on another sidewall, installed and stirred fan 16 equably in the indoor circulation of cooking in microwave oven.The upside of micro-wave oven built-in heater 10, and be provided with fan 11 in the indoor circulation of cooking in microwave oven for the heat that heater 10 is produced.
As above traditional micro-wave oven of structure is when utilizing heater 10 to cook, drive fan 11 when driving heater 10.At this moment, to be provided to cooking in microwave oven by fan 11 indoor for the heat that produces of heater 10.
Traditional micro-wave oven drives when starting magnetron 12 and stirs fan 16 when utilizing magnetron 12 to cook.At this moment, to spread to cooking in microwave oven indoor by stirring fan 16 for the microwave that magnetron 12 produces, and improves the cooking performance of food.
But the microwave stove with conventional art of said structure has following shortcoming.
To have the cooking in microwave oven performance that produces microwave function and fan functionality in order improving, the microwave of generation in the dispersion microwave stove cooking room and the device of heat need to be set respectively.In the micro-wave oven of conventional art, the problem of microwave has obtained solution by having adopted the stirring-type fan; And the heat problem that heater produces has obtained solution by having adopted convection fan.But need two fans be installed in a micro-wave oven, this point has not only caused the rising of micro-wave oven manufacturing cost, and has increased the volume of product, has finally reduced the purchasing power to product.
Summary of the invention
Technical problem to be solved by this invention is that a kind of control method of passing through the fan for microwave oven of convection fan dispersion microwave and heater heat is provided.
The technical solution adopted in the present invention is: a kind of control method of fan for microwave oven, and when starting micro-wave oven, the start-up control program, control program included as the next stage: judge whether the stage into heater formula cooking method or magnetic control tubular type cooking method; If judged result is a heater formula cooking method, then automatically starts fan, drive the stage of heater until end of cooking; If judged result is a magnetic control tubular type cooking method, then judge whether to select to start the stage of fan; If select to start fan, then drive fan, drive the stage of magnetron until end of cooking; If non-selected startup fan then only drives the stage of magnetron until end of cooking.
The present invention can bring following effect: at first, possessing microwave generation function, and in the micro-wave oven of internal heater, only a fan need be set, thereby can reduce manufacturing cost, reducing number of components.Secondly, when carrying out microwave cooked mode, by the driving of fan, it is indoor that microwave is dispersed in cooking in microwave oven uniformly, thereby can improve cooking performance.By above advantage, can improve the purchasing power of product.

The specific embodiment
Below, in conjunction with the accompanying drawings, the control method of fan for microwave oven of the present invention is described.
As shown in Figure 2, micro-wave oven of the present invention is provided with magnetron 12 on sidewall, and the microwave that magnetron 12 is produced to be distributed to cooking in microwave oven indoor.Be provided with heater 10 and fan 11 on the top of micro-wave oven.
The heater shown in Fig. 3 a and the structure of fan are: be provided with convection fan 11 in the inside of heater 10.
The top of micro-wave oven is provided with top panel 44.Top panel 44 is shown in Fig. 3 b, and microwave is easier to be passed through in order to make, and is provided with inlet hole 42 on top panel 44.That is, on top panel 44, the part that heater 10 and fan 11 are set is provided with a plurality of inlet holes 42 on every side with it.
Below, the control action process of as above fan for microwave oven of the present invention is described.
As shown in Figure 4, when starting micro-wave oven, the start-up control program.The control method flow process of fan for microwave oven is as follows:
At first, judge whether to needing the cooking of heater 10 heats during the cooking mode of selected micro-wave oven.(the 100th stage)
In the 100th stage, then indoor if judged result is the cooking of heater formula for the heat of heater 10 generations is delivered to cooking in microwave oven, must drive fan 11.(the 103rd stage)
Judge whether to finish the cooking.(the 106th stage); If finish the cooking, then finish.If do not finish the cooking, then turned back to for 103 stages.
If when the result who judges in the 100th stage is not the cooking of heater formula, confirm whether be magnetic control tubular type cooking method (the 109th stage),, magnetic control tubular type cooking method starts (the 112nd stage) if then judging whether to have selected fan 11.Then turned back to for the 100th stage if not magnetic control tubular type cooking method.
The 112nd stage was to utilize microwave when work, and in order to satisfy the cooking performance of food, and the microwave that magnetron 12 is produced is dispersed in the indoor stage of cooking in microwave oven.Thus, when simply cooking or there is no need drive fan, the driving of fan 11 will can not be selected.In the automatic-cooking pattern, can automatically set the selection of fan 11.
In 112 stages, when not selecting the driving of fan 11, then control part (not looking among the figure) only drives magnetron 12 and cooks, up to end of cooking.(the 114th stage, the 115th stage)
If in 112 stages, during the driving of selected fan 11, start fan 11.Also drive simultaneously magnetron 12.(the 118th stage)
By 118 stages, it is indoor that the microwave that produces in the magnetron 12 spreads to cooking in microwave oven by fan 11.Such action continues to carry out till finishing the cooking.(the 121st stage)
Promptly, in the present invention, in the micro-wave oven of function that possesses the generation microwave and internal heater, when utilizing heater 10 cookings, it is indoor that the heat that automatic startup fan 11 produces heater 10 is delivered to cooking in microwave oven, and in microwave cooked mode also drive fan 11, it is indoor that the microwave that magnetron 12 is produced spreads to cooking in microwave oven, improves cooking performance.Particularly in the present invention, the size that becomes microwave easily to pass through in the size design of the indoor end face inlet hole 42 that circulates of cooking in microwave oven heat that heater 10 is produced.
Thus, main thought of the present invention is in the micro-wave oven that possesses microwave generation function and internal heater, and when utilizing microwave to cook, it is indoor to utilize fan that microwave is dispersed in cooking in microwave oven.Believe that in the designed technical field of the present invention knowledgeable people of the same trade can bring the variation of renewal to the present invention.
