Detailed description of the invention
Below with reference to the accompanying drawings and describe the utility model in detail in conjunction with the embodiments.
As shown in Fig. 1 to 2, according to electromagnetic oven of the present utility model, comprise housing 40, panel 10, heater coil 20 and control device 30, electromagnetic oven also comprises distance detection device 50 and/or temperature-detecting device 60, and distance detection device 50 and/or temperature-detecting device 60 are established on the faceplate 10; It is inner that heater coil 20 is arranged on housing 40, and be positioned at below panel 10, heater coil 20 is multiple, and the range information that control device 30 detects according to distance detection device 50 and/or the temperature information that temperature-detecting device 60 detects control each heater coil 20 respectively.The utility model is by arranging distance detection device 50 and/or temperature-detecting device 60, and make heater coil 20 for multiple, thus the temperature information that the range information that can detect according to distance detection device 50 and/or temperature-detecting device 60 detect controls each heater coil 20 respectively, such as increase or reduce the electric current of certain or certain several heater coil 20, thus make the more uniform temperature in the whole the bottom of a pan; Also can close certain or certain several heater coil 20, the heater coil 20 not being positioned at the bottom of a pan not worked economize energy, makes electromagnetic oven more energy-conservation.
Particularly, shown in composition graphs 1, distance detection device 50 and/or temperature-detecting device 60 are along starlike line distribution on the faceplate 10 (being two starlike lines in FIG).When to arrange distance detection device 50 and temperature-detecting device 60 simultaneously, distance detection device 50 and temperature-detecting device 60 are installed in same position correspondence, and use together, distance detection device 50 detects the vertical range of pan apart from this device, thus judge shape and the size of pan, open corresponding pattern; Temperature-detecting device 60 is mainly used to the height detecting top pan temperature, adjusts the size of the electric current of corresponding electrified regulation coil, make heating evenly.
It should be noted that, when only arrange distance detection device 50 or only set temperature checkout gear 60 time, the utility model can realize the function simultaneously arranging distance detection device 50 and set temperature checkout gear 60 equally, just effect relative mistake some.Such as, when distance detection device 50 is only set, shape and the size of pan is judged by distance detection device 50, when pan is pannikin, correspondingly can close the heater coil 20 not in the bottom of a pan, make electromagnetic oven more energy-conservation, when pan is circular bottom pot, the electric current of the heater coil 20 of outer rim can be increased, but owing to there is no temperature-detecting device 60 detected temperatures, how much heater coil 20 electric current of outer rim can only preset based on experience value if increasing, such hinge structure is also have obvious advantage.
Correspondingly, when only set temperature checkout gear 60, also shape and the size of pan can be judged according to the temperature detected, such as, when being reduced gradually by the outside temperature in panel 10 center, can judge that pan is circular bottom pot, thus the electric current of the heater coil 20 of outer rim can be strengthened, until all positions temperature is roughly equal; When panel 10 central temperature ratio panels 10 environment temperature is greater than default judgment value, can judge that pan is pannikin, the corresponding heater coil 20 can closing outer rim.
Preferably, multiple heater coil 20 arranged concentric, and the center of heater coil 20 is corresponding with the center of starlike line, thus make inspection center corresponding with heated center, be convenient to control.
As required, distance detection device 50 can be distance-sensor, range sensor, infrared range-measurement system or ultrasonic sensor.Temperature-detecting device 60 generally adopts infrared temperature detector.
The control method of electromagnetic oven of the present utility model, adopts following steps: step S1: gather the range information of distance detection device 50 detection and/or the temperature information of temperature-detecting device 60 detection; Step S2: the type and the position that judge pan according to range information and/or temperature information; Step S3: control multiple heater coil 20 respectively according to the type of pan and position, or display reminding information, thus the electric current increasing or reduce certain or certain several heater coil 20, thus make the more uniform temperature in the whole the bottom of a pan; Also can close certain or certain several heater coil 20, the heater coil 20 not being positioned at the bottom of a pan not worked economize energy, makes electromagnetic oven more energy-conservation.
Particularly, when to arrange distance detection device 50 and temperature-detecting device 60 simultaneously, distance detection device 50 mainly judges shape and the size of pan, open corresponding pattern, temperature-detecting device 60 is mainly used to the height detecting top pan temperature, adjust the size of the electric current of corresponding electrified regulation coil, make heating evenly.
Particularly, distance detection device 50 judges shape and the size of pan according to such as under type.Shown in composition graphs 3, in time using arc circular bottom pot 1, due to the bottom of a pan middle section contacts electromagnetic oven panel, detecting distance is less than or equal to preset lower limit value, in the middle of the bottom of a pan, the distance of peripheral part distance electromagnetic oven panel increases gradually, distance detection device 50 detects that the distance of the bottom of a pan distance panel increases from inside to outside gradually, now, the pan that electromagnetic oven control device 30 automatic decision uses is circular bottom pot, and then control electrified regulation coil current size, make loop current in electrified regulation coil less, outer loop current is larger, thus cause magnetic field, outer ring to be greater than inner ring, increasing electromagnetic oven adds heat for peripheral edge portion around the circular pot the bottom of a pan of arc, thus make heating more even.Now temperature-detecting device synchronously can adjust according to the temperature of the pan above it amount needing high current further, ensures homogeneous temperature.
Similarly, shown in composition graphs 4, when using pan 2, the distance that the distance detection device 50 of electromagnetic oven panel responds to whole pan distance from bottom electromagnetic oven panel is all less than or equal to preset lower limit value, then judge to use pan to be pan, control all heater coils 20 according to normal mode work, namely all heater coil 20 size of current are substantially equal.
Shown in composition graphs 5, when distance detection device 50 detects that the distance that in the middle of the bottom of a pan, a part is local is zero, and the distance in place around other is greater than or equal to preset upper limit value (namely pan not detected), then judge to use pan as pannikin 3, then close the heater coil 20 that electromagnetic oven outermost does not need work, make electromagnetic oven more energy-conservation.
Due to distance detection device 50 diametrically star-shaped wire distribution on electromagnetic oven panel of electromagnetic oven, form the induction point of multiple symmetry, put partially to prevent pan, electromagnetic oven can judge according to the detection case of each point, when multiple point meets time, just can close corresponding coil, or prompting user pan is put partially.
Shown in composition graphs 6, when distance detection device 50 is when at the bottom of curved circular, pan is put inclined time, the place that the bottom of a pan detecting distance is less than or equal to preset lower limit value is not the central authorities of panel 10, the range deviation that pan both sides detect is comparatively large (as Fig. 6) also, this timed unit 30 judges that pan is put partially, user's pan can be pointed out to put partially with voice or display screen display.
As shown in Figure 7, when pan 3 is put inclined time, distance detection device 50 detects that on the right side of electromagnetic oven panel central authorities, the bottom of a pan is less than or equal to preset lower limit value relative to the distance of panel, left side is infinitely great relative to the distance of panel, namely pan (as Fig. 7) is not detected, now also judge that pan is put partially, deflection right side, gives the alarm equally.When deflection left side or upper and lower sides, determination methods is the same.
It should be noted that, when pan is pan 2, pan 2 directly contacts with the panel 10 of electromagnetic oven, when pan is circular bottom pot 1, also has the part the bottom of a pan directly to contact with the panel 10 of electromagnetic oven.In theory, the part that the bottom of a pan directly contacts with the panel 10 of electromagnetic oven, the distance that distance detection device 50 detects should be zero, but consider the out-of-flatness in the bottom of a pan itself, the bottom of a pan or electromagnetic oven panel 10 be stained with impurity (greasy dirt, granule food) all can adjust the distance measure produce certain influence, thus, in the utility model, pass through preset lower limit value, effectively can eliminate the impact of these factors, namely the distance detected when distance detection device 50 is less than or equal to preset lower limit value, both can be judged as directly contacting with the panel 10 of electromagnetic oven.
Similarly, when can't detect pan, in theory, the distance that distance detection device 50 detects should be infinity, but consider that may to arrange some things (as lampblack absorber etc.) measurement of adjusting the distance above pan causes interference, thus, can think that distance can't detect pan when being greater than or equal to preset upper limit value.
When only arranging distance detection device 50, distance detection device 50 is used for judging shape and the size of pan, determination methods with distance detection device 50 is set simultaneously and temperature-detecting device 60 is similar, but owing to there is no temperature-detecting device 60 detected temperatures size, when being judged as circular bottom pot, the size of Current adjustment can be preset based on experience value.
When only set temperature checkout gear 60, temperature-detecting device 60 also can be utilized to judge the size and shape of pan, the temperature information such as detected when temperature-detecting device 60, for be reduced gradually by the outside temperature in panel 10 center, judges that pan is circular bottom pot; The temperature information detected when temperature-detecting device 60 is equal by the outside temperature in panel 10 center, judges that pan is pan; When temperature-detecting device 60 detect temperature information be panel 10 central temperature ratio panels 10 environment temperature be greater than preset upper limit value time, can judge that pan is pannikin; The temperature information detected when temperature-detecting device 60 is that thermal self-restraint stress departs from panel 10 center, or the temperature difference of panel 10 symmetric position exceedes preset upper limit value, judges that pan is put partially.After judging pan shape and size, processing mode is similar to the mode simultaneously arranging distance detection device 50 and temperature-detecting device 60.
It should be noted that, the temperature information that temperature-detecting device 60 detects is equal by the outside temperature in panel 10 center, and be not equal in absolute sense, temperature difference, in certain preset range, can be thought equal.
As can be seen from the above description, the utility model the above embodiments achieve following technique effect:
According to electromagnetic oven of the present utility model, by arranging distance detection device and/or temperature-detecting device, and make heater coil be multiple, thus the temperature information that the range information that can detect according to distance detection device and/or temperature-detecting device detect controls each heater coil respectively, such as increase or reduce the electric current of certain or certain several heater coil, thus make the more uniform temperature in the whole the bottom of a pan; Also can close certain or certain several heater coil, the heater coil not being positioned at the bottom of a pan not worked economize energy, makes electromagnetic oven more energy-conservation.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
