The relation of expression key viewing area F and 6 enter keies 83,95～99 in Fig. 6.Be arranged on 6 keys (below be also referred to as display key or soft key) 84,100～104th of key viewing area part F, change the virtual key in the liquid crystal panel of function according to scene, actual operation is corresponding and near the enter key (being also referred to as F1～F6, function key) 83,95～99 of configuration by operation and each key 84,100～104, and will import (circuit for controlling electricity turning 200 described later) by suitable operation signal with operating each key 84,100～104.

In addition, as the method that 6 enter keies 83,95～99 are individually shown, have and character is appeared in one's mind in key part or by light-emitting diode etc. it is lit a lamp or emphasize various methods such as the color of key part or brightness, in the present embodiment, constitute that the various parameters that will with the condition that can import be prerequisite (as heater block, heating-up temperature or the time of object, energising amount etc.) are set needed character and mark (arrow etc.) is presented on the display key part 84,100～104.

The prompting key of being made up of hardkey (Tips key) 85 is set in front of the right side of enter key 104.This key is corresponding with the Tips viewing area G of key 104 tops, under the situation that has shown " zero i (i) " that specific mark, for example reference information (prompting) are meaned on its viewing area, as long as press this prompting key 85, just can show as shown in Figure 14 to make to be presented on the boot section E of central authorities' input/display part 80 with character to cooking useful details etc.

Fig. 8～Figure 17 is the action specification figure of the demonstration example of expression display key 84,100～104 and enter key (function key) 83,95～99.

6 display keys 84,100～104 are distinguished thereunder individually each self-configuring LED, to the bright effective input display key of each manipulation fields millet cake.Display key 100～104 for example shown in Figure 8 becomes effectively (active state).Among the figure, AM schematically shows the activity mark that is in the activity situation.In fact be not only and carry out lighting a lamp of this given shape, universe that can also be by highlight display key 84,100～104 or profile only perhaps change method such as color, represent to be in the activity situation.

In addition, even if for the also invalid key of operation in the display key 84,100～104, by becoming ash (with contrast and character content is thin out show) or not showing that (only make the key outer shape is thin out to be shown) distinguish.In Fig. 8 only 1 show that 84 become and become ash or do not show.Also have or not by the LED that thereunder are provided with individually for function key 83,95～99 in addition and light a lamp, effectively function key can enough visual differences.

In Fig. 8, the function key 83 corresponding with enter key 84 do not make LED light a lamp, even if press the function key 83 that this LED does not light a lamp, effectively operation signal can not be taken into (control program for the action of determining circuit for controlling electricity turning 200 can not become effective operation instruction signal) from top-operation portion 20 among the circuit for controlling electricity turning 200 of postscript.

That is to say, in execution mode 1, programme so that when the user has watched central demonstration/input part 80, can promptly be familiar with/understand desirable display key slightly simply, and on unwanted display key, not show any like this function name of selection or the title of heater block.In addition, import effective display key can enough characters or luminous, color etc. differentiate.In addition, the function key 83,95～99 corresponding with this effective display key also waits by color or light and shows that it is in effectively (activity) state.

The active state that is to say the active state of 6 display keys 84,100～104 and 6 function keys 83,95～99 changes to each input scene, but both correspondences usually.For example, in Fig. 8, be at display key 100 (because activity mark AM light a lamp) effectively under the scene of (active state) function key 95 also become effectively (active state).

In Fig. 8, the picture area 81 of central authorities' demonstrations/input part 80 shows initial conditions, so the function key 83 corresponding with display key 84 just becomes inertia, even if represent that pushing this key 83 display key corresponding with it 84 also can't carry out input operation.

The comment that on display key 84, is showing " initial picture ", owing to become initial picture, so do not operate the necessity (demonstration self of this initial picture and so on is presented on the display key 84, but makes its demonstration) of this key 84 for the convenience on illustrating.

In addition, after Fig. 6 or Fig. 8, " returning " such display key 100 is wanted to turn back in the process of input of carrying out cooking conditions etc. under the situation of last input picture or display frame and is pushed.The enter key 84 of " initial picture " is operated under no matter which stage thinking to turn back at one stroke the situation of initial picture in.

The key diagram of the central authorities' demonstration/input part 80 that Fig. 9 is expression when the state user of Fig. 8 presses 3KW key 86 (with reference to Fig. 6) and the demonstration example of enter key (function key) 83,95～99.If 3KW key 86 is pressed, the then instruction of circuit for controlling electricity turning 200 input menus being selected by the input signal of enter key 86, this control circuit sends the picture of instruction with displayed map 9 for this central authorities' demonstration/input part 80.

The district C2 in the demonstrations/input part 80, right heater coil 6R of central authorities automatically with enlarged areas to several times, according to literal shown on the C1 of viewing area as can be known its firepower grade to be configured to 12 in 12 grades (maximum) be 3KW.

Owing to can't reduce, so the display key 102 that is used for firepower is reduced is inertias, the function key 97 corresponding with it becomes inertia about this firepower.In addition owing within 2 minutes, 5 minutes, 10 minutes, show 2 fens by initial setting conduction time, so thinking and to become in these 2 minutes under 5 minutes the situation, pressing 3KW key 86 once more or showing the display key 103 that makes " → " mark that time or temperature increase and press function key 98 and get final product in order to operate.In the case, the function key 98 that is used for time lengthening (by 5 minutes or 10 minutes) becomes movable the demonstration, otherwise the function key 97 corresponding with the display key 102 that is used to the time that shortens becomes ash (because can't be reduced to below 2 minutes).But, after setting 5 fens for, turn back under 2 minutes the situation, because this function key 97 becomes activity, get final product so it is pressed.

As shown in Figure 9, the boot section of central authorities' demonstration/input part 80 E (being equivalent to alarm/guide display district) go up the user can easily recognize select within the cooking time was from 2 minutes, 5 minutes, 10 minutes, its system of selection is to press 3KW key 86 or showing with 97,98 pairs of function keys that the display key 102,103 of " → ", " ← " mark is operated to get final product in addition.

So, on the E of boot section, for example can carry out showing auxiliary etc. or the important alarm of the explanation of the operating function that its main displaying contents is various keys or operating process up to the character of 50 characters.

Figure 10 is expression from the state user of Fig. 8 central authorities' demonstration/input part 80 during by the convenient Menu key 93a of bottom right IH (with reference to Fig. 6) and the key diagram of the demonstration example of function key 83,95～99.In Figure 10, if key 93a is pressed, district C2 then in central authorities' demonstration/input part 80, right heater coil 6R is enlarged-area automatically, and show various cooking menus (for example, fried food, stew etc.) in the left side, as the firepower that is suitable for stewing the firepower grade being become 5 in 12 grades by initial setting as can be known is 625W (weak firepower).

Because this firepower can be altered to the firepower that the user wishes beyond initial set value, so wanting firepower is set as below the 563W under the situation as low 1 grade, if for operation display key 102 is pressed 1 grade that just can descend for 1 time with function key 97, if press 2 times then drop to 2 grades (500W).Otherwise pressing function key 98 under the situation that improves firepower gets final product.

In addition, if the display key 101 shown in the arrow of operation conduction time above-below direction, the condition of being imported just becomes " conduction time ".That is to say, in Figure 10, can carry out " time: 0 minute " time set so partly.Thereby, function key 98 is pushed 2 times wanting cooking time set is become under 2 minutes the situation.Because Figure 10 is in the grade of such setting-up time, does not have the time (0 minute) is reduced (shortening), so the function key 97 inactive (yet can't carry out any input) of display key 102 correspondences even if press this key 97.

In addition, do not carrying out time set and thinking to carry out again under the situation of firepower setting, press the function key 96 corresponding from the state of Figure 10 with display key 10, as the arrow demonstration of display key 101, can make input object move to " firepower " that is presented at its top position, input object can be become the firepower hurdle from time fences from " time ".

In addition, cooking menu is altered under the situation of " stop timing device " from " stewing " wanting, just can goes the rounds like that as " stew → insulation → fried food → stop timing device " if press function key 96, thus need only and stop timing device part identical.

In addition, the stop timing device is meant to be selected the firepower of left heater coil 6L and right heater coil 6R within grade 1 (120W), 2 (300W), 3 (563W)～8 (1KW), can carry out 1 hour 30 minutes (90 minutes) function by timer, for example can realize the use of right heater coil 6R energising being cooked and so in 29 minutes with firepower 8 with the interior continuous cooking.In addition, even if the central heater block 7 of heater block in timer timing when running also can use.

In Figure 10, energising mark 50 is by lighting a lamp or lighting to extinguish and represent that right heater coil 6R energising is in to add and pine for.Energising mark 50 appears at the right position of the title that has shown each heater block as shown in Figure 6.

Figure 11 is illustrated in user under the state of Figure 10 stewes the demonstration example of central authorities' demonstration/input part 80 when cooking and function key 83,95～99 by the convenient Menu key 93a of bottom right IH key diagram.In this example, on the district of right heater coil 6R C2, showing to stew 40 minutes setting of the cooking, be 7 minutes through 33 fen remaining time now.

Like this, after the selection of having carried out heater block, automatically turn back to the standard area, as shown in Figure 11 the area of each viewing area A2, B2, the C2 approximate equality that becomes if enter viewing area A2, B2, the C2 of the then specific heater block of cooking running.And on the viewing area of right heater coil 6R, show energising mark 50.

The state (initial picture) that Figure 12 is illustrated in Fig. 8 down user is selected the display key 103 of the grill cooking, and the situation of carrying out the automatic grill cooking when pressing function key 98.If function key 98 is pressed, viewing area D then in central authorities' demonstrations/input part 80, the culinary heater of oven cook/grill is automatically with its enlarged areas, and shows various cooking menus in the left side (for example, grill, manual grill etc.) automatically.

In automatic grill, except that " doing roasting ", also select the heating menu of " cube meat ", " small fish ", " smearing the seasoning matter barbecue " and so on as shown in Figure 12.Its system of selection is only to press function key 97,98.In the case, whenever press display key 103 (function key 98) and " do baking → cube meat → small fish → smear seasoning matter and roast " such menu just occurs.If press display key 102 (function key 97) in addition, just can with above-mentioned opposite direction, as " cube meat → do roasting ", it is shown in turn and selects.

In addition, if press function key 96 and operate display key 101, just can set the barbecue quality of doing when baking.Wanting to increase under the situation of barbecue quality, on the basis of the input pattern that the barbecue quality is set, press function key 98, get final product otherwise under the situation of wanting to reduce, press function key 97.Push the barbecue quality at every turn and all change 1 grade.If be set as under 4 the state with function key 99 operations in the grade that will roast quality as shown in Figure 13 then and be equivalent to the enter key 104 of initiate key then cooking beginning.

Under the situation of the cooking of carrying out Figure 12～shown in Figure 13, under door 70 states of opening of heating chamber 19, on the E of viewing area, show the attention message of " door of zero i (i) grill is being opened " and so on.In addition as shown in figure 13, show that with message fishes such as " saury ", " scad ", " sardine " also can do roasting.

Figure 14 is the key diagram of the demonstration example of expression Tips." Tips " handles by the meaning of useful information or general knowledge and so on, for the content that makes known facilitating functions or cooking lime light or solve to utilize the user's of control puzzlement is automatically informed under the situation that the user wants to learn and prepared thinking.Applying flexibly mainly as method (how to) countermeasure in execution mode 1, is purpose more cosily to carry out the IH cooking.

Its action is displayed on to press when viewing area G goes up at " zero i (i) " icon (i is the initial of prompting) and shows qualified content when corresponding hardkey is pointed out key (Tips key) 85 (with reference to Fig. 6).

In addition, as its displaying contents, except that shown in Figure 14, for example also has following Example.

(1) at inform (prevent to forget and cut off/take off cigarette filter automated cleaning etc.) of operation/intention action that it doesn't matter of user.

(2) content that allows the people understand for safety grasps automatic-cooking (fried food, automatic grill) again brilliantly.

(3) inform about the cooking distinctive characteristics of armamentarium (roasting unequal).

(4) comprehensive requirement of the peace of device for cooking or alert content, at the corresponding method of alarm.

Think in Figure 14 to learn in more detail that as long as the user presses function key 98, and 103 display frames of operation display key just switch to down one page under the situation of the benchmark that the barbecue quality of automatic grill is regulated.

" automatically grill " cooking among Figure 13 and Figure 14 is meant the conditions such as setting according to the kind of heating object or size, barbecue quality, the state that the temperature of heating chamber 19 of observing the microcomputer that is built in the power control apparatus 200 of cooking device rises also calculates the time of playing after the cooking beginning till the cooking is finished, and with this result of calculation as being expressed as " after doing roasting 18 minutes " fiducial time as shown in figure 15.

On the other hand, " manually grill " is meant and can freely sets the cooking time, wanting to increase under the situation of barbecue degree after the grill end automatically, can also be set as this manual grill later at automatic grill end of cooking.In addition, after end of cooking, sometimes circuit for controlling electricity turning 200 carries out the automated cleaning (the cigarette filter that takes off that will work to decompose cigarette carries out the certain hour energising) of heating chamber 19, and " in the automated cleaning " etc. is presented on the E of viewing area in the case.

In addition, although under the situation of also untouched motionless placement more than 30 seconds that call attention to " the grill door is being opened " as shown in Figure 15, hot gas outwards lets out from heating chamber 19, temperature in the heating chamber can not increase a lot, and the setting of cooking conditions becomes invalid so the microcomputer of circuit for controlling electricity turning 200 is programmed.At this moment, send attention message as shown in Figure 15, urge the user to note being in correct user mode.

Under state shown in Figure 15 " 180 ℃ of left IH fried food temperature ".Its implication means that left heater coil 6L is energized, and its conduction time, initial all timing settings became 20 fens (after the cooking beginning, from this 20 fens countdowns, showing with 1 scale division) in this cooking device.In addition, " setting 180 ℃ " means that left heater coil 6L is energized, and the temperature of the oil of fried food pot is configured to 180 ℃.

In addition, can also not as described above initial setting (default) time set to be become 20 fens, for example came design control procedure in 10 minutes like this but be set as.

In addition, under the state of Figure 15, select the display key of central heater block 7 not to be shown.The function key 96 corresponding with display key 10 is also inactive, so also can not be imported into circuit for controlling electricity turning 200 even if hypothesis is pressed key 96 any effective instructions.During carrying out grill/oven cook, the consumed power that cooking device is all suppresses in certain limit like this, so central heater block 7 just can't use simultaneously.

So, central authorities' demonstration/input part 80 is in order to allow the user visually confirm, the area of the viewing area of the second viewing area A2, B2, C2 can be according to it being changed greatly content displayed.The second viewing area A2, B2, C2 are these two states of abnormality that show " second condition " set condition such as cooking time, design temperature in each viewing area and " heating-up temperature and physical quantitys such as electric current, voltage ".

For example, the controlled condition of left heater coil 6L is being set, under the situation such as affirmation, for example can enlarged greatly accounting for all areas (from the state of Figure 15) as shown in Figure 16 as the district A2 of object.Promptly, under the state of Figure 15, carry out input operation for display key 100 to usefulness " left IH " and demonstrations such as character or mark, the user if pressing function key 95, (becoming active state) just becomes as shown in Figure 16 demonstration, so can confirm the needed information of the cooking of left heater coil 6L.

In Figure 16, though the heating-up temperature of oil is configured to 180 ℃ at first,, just temperature can be turned down 1 ℃ at every turn if press the function key 97 corresponding with display key 102, if press on the contrary the function key 98 corresponding, just temperature can be heightened 1 ℃ at every turn with display key 103.

In addition, though be configured to 20 fens at first conduction time, just cuit can be switched to " time " from " temperature " (example: 180 ℃) if press function key 96.Then, after being set as the time input pattern like this, if press the function key 99 corresponding with display key 104, just can be by the above condition starting-up oil deep-fried food cooking (in the stage of having started, the mark 50 of switching on is as shown in Figure 16 lit a lamp in the location right of the demonstration of " left IH ").

In addition, in the case, on the E of viewing area, for example the user is shown " please oil mass being cooked " more than 0.6L, show the employed oil of fried food is set as give like this with the literal of noting more than 0.6 liter.That is to say to have and show that fried food cooks the function of points for attention such as the amount of needed oil or heating-up temperature.For example if the oil of only putting into 0.2 liter of fried food in pot heats, then this oil will rise to more than 300 ℃ because of firepower one gas of heater block, and the danger of breaking out of fire accident etc. is just arranged.

The following user of state (initial picture) that Figure 17 is illustrated in Fig. 8 uses right heater coil 6R, and has in use carried out the state of the grill cooking.Under the situation that right heater coil 6R is used earlier, display key 84,100～104 becomes the state of Figure 11 or Figure 15.That is to say that as shown in Figure 15 show " grill " literal on enter key 103, corresponding function key 98 also becomes active state, so if press this key 98 then the viewing area of grill/oven cook is enlarged as shown in Figure 17.Go up energising show tags 50 at the viewing area C2 that is expressed as " right IH " of the right heater coil 6R of expression and light a lamp (perhaps light and extinguish) under this state, right as can be known heater coil 6R is in to add and pines for.

On the other hand, central heater block 7 and left heater coil 6L are owing to showing that on its viewing area B2, A2 energising show tags 50 or other expressions are in character or the picture in the energising, so do not use (stopping) as can be known.In addition, the picture of the state of Figure 17 started with automatic grill do roasting after, from about several seconds to 10 second after, automatically return to the "on" position initial picture as can be known of all heater coil 6L, 6R, 7,110A, 110B as shown in Figure 6.

In addition, like this purpose that two temperature sensors is set at left heater coil 6L and right heater coil 6R be by in the inside that keeps frame 330R, 330L from the weather side position of the cooling fan 262,315 of postscript and the two mensuration temperature that keep the bottom center portion of frame 330R, 330L to separate like this, more accurately temperature is detected.

Each temperature detection state difference of a pair of temperature sensor S2A, S2B, a pair of temperature sensor S4A, S4B, the fiducial temperature that is judged to be abnormal temperature is also different, but because left heater coil 6L and right heater coil 6R are main heater blocks, and high temperature, a pair of temperature sensor is dual to be monitored so be provided with.

Equally as shown in Figure 3, at the 370L of the inside of body 1 left space portion also with the 370R of right space portion equally respectively in the cooling of a plurality of high voltage electrical parts (power transformer and high-frequency converter control circuit parts etc.) 371L with conduit 372L or its inlet portion top end face configuration temperature sensor S8, again at the top end face configuration temperature sensor S9 of the heat release panel 373L of the aluminum that the high-voltage electrical apparatus parts have been installed.

Circuit substrate 390 is in the inboard of above-mentioned two cooling duct 372R, 372L, by fixedly high voltage electrical parts 371R, 371L, a plurality of foots 391 support.

The inside of body 1 is such shown in the cross-sectional view of Fig. 2, to clip the mode of heating chamber 19 from both sides, setting has left space bar 374L and the right septum plate 374R from the inner bottom surface of body 1 to the top end face size, divides to form left space 370L of portion and the 370R of right space portion between the left and right sides sidewall of left space bar 374L and right septum plate 374 and body casing 2.

The cooling that is arranged on the anti-U font section configuration of the 370R of right space portion is used such as the good material of such heat conductivity such as aluminium with conduit 372R and is formed, and the side cooling fan 261 that is arranged at inlet portion is supported by motor FM within it.And, when this motor FM drives, from shown in the arrow F1 of Fig. 3, like that extraneous air being attracted to the 370R of right space portion at a large amount of suction holes 375 that form of the back side of body casing 2 right positions.

Equally, the cooling conduit 372L of anti-U font section configuration also is set at the 370L of left space portion, side entrance portion is provided with cooling fan 263 and motor FM within it, when this motor FM drives, from extraneous air being attracted to the 370L of left space portion like that shown in arrow F1 at a large amount of suction holes (not shown) that form of the back side of body casing 2 leftward position.

Near the top end face in right space portion 370R the place ahead, hold respectively in the above cooling fan 262 with the following housing 377R that has formed suction inlet 376R by horizontal arrangement, suck from cooling with the export department of conduit 372 the air of coming that rises at suction inlet 376R, and the one o'clock angle part (shown in arrow F3 like that) of superjacent air space 275 of it being divided up and down the metallic space bar 334 of body 1 inside above heating chamber 19 blows out.

Equally, near the top end face in left space portion 370L the place ahead, hold respectively in the above cooling fan 315 with the following housing 377L that has formed suction inlet 376L by horizontal arrangement, suck from cooling with the export department of conduit 372 the air of coming that rises at suction inlet 376L, and the angle part, left front (as arrow F3) of superjacent air space 275 of it being divided up and down the metallic space bar 334 of body 1 inside above heating chamber 19 blows out.Cooling fan 262 is set at and drives with on the rotating shaft 262B of motor, and same cooling fan 315 is set at and drives with on the rotating shaft 315B of motor.

The housing 377R of cooling fan 262 connects on the window 379R that is arranged at right septum plate 374R.Equally, connect at the housing 377L that is arranged at cooling fan 315 on the window 379L of left space bar 374L.

In Fig. 5, adopt the formation that all is input to circuit for controlling electricity turning 200 from the temperature data of above-mentioned 9 each temperature sensor S1～S9 through temperature sensing circuit 311.

Fan drive circuit 260 is according to the temperature measuring situation from temperature sensing circuit 311 then, the time running cooling fan 261,262,263,315,316 usefulness commonly used generations wind cool off so that temperature measuring partly is no more than set point of temperature and becomes high temperature separately.But; nonetheless still surpassing under the situation of set point of temperature rising; the abnormal temperature signal is imported into circuit for controlling electricity turning 200 from temperature sensing circuit 311; the power supply of heater blocks such as left side heater coil 6L, right heater coil 6R and heater 231 is cut off or by the system limit, the guard signal that is used for safe action is exported to each heater block from circuit for controlling electricity turning 200.

That is to say that the abnormality detection parts are made of circuit for controlling electricity turning 200, temperature sensing circuit 311 and current detection sensor 227 etc.In addition, about the running of above-mentioned each cooling fan will after be described in detail.

In Fig. 2, to guide plate 378R, 378L in the blow-off outlet 262A of cooling fan 262,315, the anterior position of 315A, be set at space bar 334 above, have the V font, and have and to distribute to central authorities' input/display part 80 and left heater coil 6L, right heater coil 6R effect separately from the cooling air of cooling fan 262,315.

The air that promptly, form air stream F3 that central authorities' input/display part 80 is cooled off, cools off left heater coil 6L and right heater coil 6R from both sides respectively flows F5 and F4.Then, finally these air are able to exhaust like that from right exhaust outlet 74 and left bank gas port 75 shown in arrow F8 Fig. 3.

A pair ofly be splayed to guide plate 380R, 380L in the narrow more more backward mode of rear portion side and be arranged on the space bar 275, have air is flowed the effect that F4, F5, F6 compile under exhaust outlet 74,75 superjacent air space 275 of space bar 334.

Fig. 4 is the top sectional drawing of the heating device of Fig. 1.As shown in Figure 4, top board 5 following and the space that covers between all heat-barrier materials 300 of the top end face of heating chamber 19 are divided into two spaces up and down by space bar 334, and form superjacent air space 275 and following side space 274.

Air Blast fan 314 is set at down side space 274 inner rears, attract room air from the suction hole (not shown) of the rear portion central authorities that are arranged on body casing 2, and (following side space 275) plane earth is sent cooling air in mode in dextrorotation or the dextrorotation certain above the heating chamber among body 1 19, below following side space 274, generate distinguished and admirable F7, discharge from exhaust outlet 74,75 at last.

In addition, superjacent air space 275 and following side space 274 are divided by space bar 334 or conduit (not shown) etc. and on the way can not be intersected until exhaust outlet 74,75, can not interfere mutually etc. so flow through the air in two spaces 274,275, be discharged to the outside of body 1 respectively.

In addition, two cooling fans 262,315 are configured to the superjacent air space 275 that its blow-off outlet faces space bar 270, in the running, will deliver to the place ahead part of its superjacent air space 275 equally from suction inlet 376L, 376R institute inhaled air.

As shown in Figure 4, the front portion in space 275 is provided with the crystal liquid substrate 280 of the liquid crystal panel that constitutes central authorities' demonstration/input part 80 up.Crystal liquid substrate 280 its bottom surface sides cover with heat-barrier material 281, are accommodated in only metal casing 282 inside of top opening, are fixed by casing 282 to keep the mode in the space 283 of regulation below top board 5.

Intercommunicating pore 271 forms a plurality of around full week of casing 282, the part from the wind of cooling fan 262,315 above crystal liquid substrate 280 is passed through, and makes crystal liquid substrate can not become high temperature thus.Form so that the direction (fore-and-aft direction of wind flow at the bottom surface of casing 282 a plurality of heat release fin 282A.Direction from left to right in Fig. 4) almost parallel improves the air cooling performance of casing 282.

As shown in Figure 4, under large-scale (heavy caliber) that fried food is cooked pot N is placed on situation on the top board 5 for a long time, particularly, under the situation of placing at the too approaching central authorities' input/display part 80 in more regular position, the position of this pot, heat from pot N just is easy to pass to central authorities' input/display part 80, and be considered to become the reason that temperature anomaly increases, so intercommunicating pore 271 is set so that the mobile improvement of cooling air.

Same also is that infrared LEDs 234 shown in Figure 5 is configured in set ditch shape space 291 between the rear end of crystal liquid substrate 280 and the heat-barrier material 281 in Fig. 4.Though do not have diagram but other infrared LEDs 235,236 also directly is horizontally placed on row, see through top board 5 to the orientation of air interchanger 239 infra-red-emitting drive signal.

In addition, on the part of the upper wall surface of framework 4 and the outer surface that constitutes top-operation portion 20, opening is set, and cover this opening with the infrared ray permeable material, part or all of above-mentioned infrared LEDs 234～236 can also be set below this permeable material.

One of the critical piece that on metal installation base plate 292, carrying the various input switch classes of top-operation portion 20, the console switch of for example operating by action button 92 and a plurality of switches of operating with enter key 97, constitutes circuit for controlling electricity turning 200 promptly " show with " microcomputer etc., with top-operation portion 20 related electric component groups 298.

On installation base plate 292, form many intercommunicating pores 297 at certain intervals, a part of sending into the cooling air of superjacent air space 275 from cooling fan 262,315 enters into spatial portion 295 by intercommunicating pore 297, so that electric component class 298 can not become high temperature because of the thermal impact of transmitting by top board 5.

As shown in Figure 2, because of being exposed to the cooling airflow F3 that sends here from cooling fan 262,315, cooled off on the top board 5 of the casing 282 of crystal liquid substrate 280 peripheries and casing 282 peripheries.In addition, electric component class 298 also is cooled simultaneously.

Control basal plate 299 is fixed on electric component class 298 on the installation base plate 292, fixes by foot 293 is installed.Distribution 93A is tied the console switch class and the electric component class of central operation portion 23, and distribution 296 is connected on the function key 83,95～99.

Sealing will seal between 6 function keys 83,95～99 etc. and the framework 4 with airtight and watertight padding 333, and the connecting line 93A of switch 93 links to each other with Switch 298 respectively with the connecting line 296 of function key 97.

In Fig. 5, pre-stand-by power source 400 replaces this source power supply and supply power for example, is made of rechargable battery under situation about circuit for controlling electricity turning 200 being cut off from source power supply 202 by mains switch 201.Thereby, from source power supply 202 to circuit for controlling electricity turning 200 at undesirable conditions such as electric generation abnormal currents, under the motionless adventurous situation of former state, when circuit for controlling electricity turning 200 self is open with mains switch 201, connects and use pre-stand-by power source 400.

In addition, though diagram not at the built-in nonvolatile semiconductor memory in the inside of circuit for controlling electricity turning 200, is being stored the information till taking place to begin unusually to cut off to source power supply from cooking device.This is when cooking device starts once more next time, and circuit for controlling electricity turning 200 is judged fault or the undesirable condition of last time, can carefully switch on.In addition, can also make the repairman of cooking device or the fault history that above-mentioned memory is read by manufacturer, useful to repairing.

Secondly, the action summary that constitutes the heating device of forming by above-mentioned is described based on flow chart.Below, each step slightly is designated as " ST ".

Figure 18 is the flow chart of the elemental motion till expression prepares to begin from power connection to the cooking.In Figure 18, this operation program is stored in the microcomputer that is in circuit for controlling electricity turning 200 inside.

At first, power plug is connected to the source power supply of 200V, and presses mains switch 201 (ST-1).

So, be supplied to circuit for controlling electricity turning 200 (ST-2) through the low supply voltage of constant voltage circuit 232 regulations.

So, circuit for controlling electricity turning 200 starts, control program to self carries out self diagnosis, inspection, at the drive circuit 244 (ST-3) of the liquid crystal display part of the drive circuit 228 of the drive circuit 260 that does not have to start respectively under the unusual situation cooling fan, left and right sides heater coil 6R, central authorities' input/display part 80.

And then drive circuit 228 is crossed small-power at left heater coil 6L, right heater coil 6R upper reaches, and comes check circuit to constitute upward not unusual (ST-4) according to the state of this electric current.

And then drive circuit 260 makes cooling fan 261,262,263,314,315 running beginnings (ST-5) with the rated current of regulation.

Temperature sensing circuit 311 reads out from each temperature sensor that adds up to 11 places to be provided with (temperature data of S1～S9), and give circuit for controlling electricity turning 200 with these data.

As described above owing to circuital current and the data such as voltage, temperature of on circuit for controlling electricity turning 200, compiling the main composition part, so as the control heating unusually of the anomaly monitoring before cooking judgement.

For example,, be judged to be and be not abnormal high temperature (ST-7) than the heat resisting temperature (for example 70 ℃) of its liquid crystal display part also under the situation of low (below 49 ℃) below 21 ℃ in the temperature of central authorities' demonstration/input part 80.

Otherwise, if then be judged to be abnormal high temperature more than 50 ℃.

Secondly, the electric current that flows through on the resonant circuit 225 that 227 pairs of current detection sensors are made up of the parallel circuits of heater coil 220 and resonating capacitor 224 detects, and the input part that is provided for circuit for controlling electricity turning 200 is exported in this detection.Then, detect because of some accident or poor flow etc. with the situation of regular current value ratio than too little current or super-high-current under, circuit for controlling electricity turning 200 is judged to be (ST-8) unusually.

The cooking begins to be ready to complete (ST-9) under the situation that does not have abnormality juding by above step (ST-7, ST-8).

But, under the situation of having carried out abnormality juding, carry out handling when unusual 1 processing as shown in Figure 18.

The action of processing 1 as shown in figure 19 when unusual.

At first, judge whether can in cooking device, correct this abnormality (ST-10) according to unusual content.

For example, in the temperature of central authorities' demonstration/input part 80 is not that heat resisting temperature (for example 70 ℃) than its liquid crystal display part is also low more than 20 ℃, but under the situation of low 15 ℃ (that is to say 55 ℃), cool off by 262 pairs of these liquid crystal display part brute forces of cooling fan, perhaps also consider to place near the top board 5 above the liquid crystal display part of central authorities' demonstration/input part 80 situation of high-temperature cooking utensil (for example just carried out fried after pot), make that this pot is mobile to get final product so the user called attention to.

But, (also comprise and urge the user that pot is moved as described above) receiving under the situation that is judged as the abnormal data that can't in cooking device self, directly correct abnormality, directly enter the action 1 (ST-13) of abnormal show from ST-10.

Thereby for being judged as the abnormal information that can correct processing, the correction of execute exception is handled.For example, as described above, in the temperature of central authorities' demonstration/input part 80 is not that heat resisting temperature (for example 70 ℃) than its liquid crystal display part is also low more than 20 ℃, but under the situation of low 15 ℃ (that is to say 55 ℃), cool off by 262 pairs of these liquid crystal display part brute forces of cooling fan, (correct processing execution unusually: ST-11) so that cooling fan 261 and cooling fan 262 both sides' supply power also increases than usual the time and 5% remains in operation.

Then, make cooling fan 261 and cooling fan the last 262 running back to monitor at interval for 30 seconds, at the appointed time through after (for example 3 minutes after), detect temperature and also worsen what by temperature sensor S3 the temperature of central authorities' demonstration/input part 80 has been carried out once more measuring than before carrying out this correction and handling, surpass 60 ℃ situation judge into " precarious position " (ST-12).

Then, central authorities' demonstrations/input part 80 alert message of becoming abnormal high temperature is with this liquid crystal display part demonstration.The content (ST-13) of on the E of viewing area, coming display abnormality exactly particularly with literal.

Then, this abnormal high temperature for example 1 minute with interior situation about not being eliminated under, circuit for controlling electricity turning 200 with 262 runnings of cooling fan 261 and cooling fan up to being reduced to below 49 ℃ after (but the longest for example 5 minutes), handover the connection to pre-stand-by power source 400, and mains switch 201 pressures are open, cut off (ST-14) from source power supply 202.

Just central authorities can be shown thus/the liquid crystal display part Yin Gaowen of input part 80 and being out of shape or the anti-possible trouble that terminates in of accident of scaling loss.

Then, carried out moment process stipulated time (for example 10 minutes) of abnormal show 1 (ST-13) from central authorities' demonstration/input part 80 after, cut off the energising (ST-14) of central authorities' demonstration/input parts 80 through drive circuit 244.

Then, the unusual temperature data of the process from ST-10 to ST-14 after the unusual generation etc. is stored at the nonvolatile memory (not shown) of circuit for controlling electricity turning 200 and goes up (ST-15).

Finish by above abnormality processing 1.

Secondly, the situation of transferring to cooking mode after just the anomaly monitoring processing finishes before the cooking in Figure 18 describes.Figure 20 has been to use the example under right heater coil 60R (right IH) situation.At first the operation scale 12R " from right to left " with previous action portion 10 rotates (setting firepower (ST-16) according to the amount of being rotated).

Operation signal from previous action portion 10 is imported into circuit for controlling electricity turning 200, in addition, be imported into circuit for controlling electricity turning 200 from the various enter keies of top-operation portion 20 (95 etc.) operation signal, cooking conditions such as firepower grade and heating time are set (ST-17).

Circuit for controlling electricity turning 200 drives drive circuit 228, to drive right heater block circuit 206R.In addition,, central authorities' demonstration/input part 80 drives, so on its viewing area C1, C2, show cooking conditions (ST-18) such as firepower and cooking time because being driven circuit 244.

Because drive circuit 228 applies driving voltage on the grid of IGBT225, so cross high-frequency current (ST-19) at heater coil 220 upper reaches.

Make pot become high temperature (ST-20) by high frequency magnetic flux thus from heater coil 220.

After this, enter the overheated cooking action of electromagnetic induction (cooking mode) (ST-21).

As shown in Figure 20, the anomaly monitoring in the cooking is controlled to have and is added thermal surveillance processing (ST-22), abnormal voltage supervision processing (ST-23), abnormal current supervision processing (ST-24) 3 supervision stages unusually.

Unusually add that thermal surveillance is handled (ST-22) though with identical shown in the ST-7 of Figure 18, but because after being the beginning cooking, so as overheated former thereby add left heater coil 6L, right heater coil 6R, central heater block 7 etc. (still, owing in example shown in Figure 20, be to use the situation of right heater coil 6R, so right heater coil 6R may become overheated strong reason).

In addition, abnormal current monitor to be handled (ST-24) and the pot that is not suitable for induction heating is as described above waited situation about being used and situation about detecting with more very few electric current of regular current value ratio or super-high-current because of some accident etc. monitors, as one of this unusual countermeasure, control through 228 couples of IGBT225 of drive circuit by circuit for controlling electricity turning 200, and the instantaneous energising that stops load coil 220.

Unusually adding thermal surveillance handles to receive the situation of heating (cooking) end signal like that or receive under the situation from user's heating stop instruction signal shown in ST-25 at circuit for controlling electricity turning 200 and finishes.Be judged to be under the unusual situation in that this a series of heating anomaly monitoring is Guaranteed, handle by abnormality processing 2.This is illustrated separately with reference to Figure 22.

Anomaly monitoring control is controlled these two stages by the anomaly monitoring of stage of the control of the anomaly monitoring in the cooking of various heater blocks and cooking device body 1 like that as shown in figure 21 and is constituted.

Heater block anomaly monitoring in the cooking is made up of the anomaly monitoring ST-28 of the anomaly monitoring ST-27 of the anomaly monitoring ST-26 of right heater coil 6R, left heater coil 6L, central heater 7, the anomaly monitoring ST-29 that carries out the heating chamber 19 of the grill cooking etc.

In addition, the control of the anomaly monitoring of the cooking device body 1 in the cooking monitors that by the temperature anomaly of the right electrical control baseplate part of body (conduit 272R inside, right side) temperature anomaly of (ST-30), body left side electrical control baseplate part (conduit 272L inside, left side) monitors that the temperature anomaly of (ST-31), central authorities' demonstration/input part 80 monitors that (ST-32) forms.This ST-32 is the supervision processing same with above-mentioned ST-7 (with reference to Figure 18).

Processing during secondly, based on unusual in the just actual gastronomical process of Figure 22 describes.In addition, Figure 23～Figure 35 of the transfer (picture 1～picture 12) of the display frame of the central authorities' demonstration/input part in the unusual generation state of reference expression.

Be judged to be when unusual " handle 2 " of transferring to Figure 22 under the situation of " having unusual " in certain at ST-26～ST-32 of Figure 21.

For example, in ST-26, the detected temperatures of temperature sensor S2 becomes under 280 ℃ the situation and is judged to be abnormal high temperature.In ST-32, the detected temperatures of temperature sensor S3 surpasses than the heat resisting temperature (for example 70 ℃) of the liquid crystal display part of central authorities' demonstrations/input part 80 also low (below 49 ℃) below 21 ℃ and become and be judged to be abnormal high temperature (280 ℃ as described above, 50 ℃ conducts with separately relevant determinating reference value) unusually under 50 ℃ the situation.

When unusual, handle to correct unusually at first in 2 and could judge (ST-34).Handle 2 when unusual, the basic consideration method of the ST-10 that could judge with the unusual correction of Figure 19 is identical.

Secondly when being judged as in ST-34 is under the situation about can correct unusually, judges that having taken place unusual is which heater block (left heater coil 6L and right heater coil 6R, central heater block 7 etc.).

Promptly, before it, specific heater block (for example right heater coil 6R) is heated instruction, and unusual the cooking takes place constantly to be in add under the situation of pining at this, just can be judged to be right heater coil 6R the source takes place unusually according to information from the anomaly monitoring step (ST-26) of this heater block.

In addition, be that the source takes place unusually from also being judged to be right heater coil 6 under the current detection sensor 227 of right heater block circuit 206R is sent to the situation of circuit for controlling electricity turning 200 equally at abnormal current.

The viewing area of this unusual heater block enlarges processing in central authorities' demonstration/input part 80 when being judged as under unusual situation has taken place in the heater block shown in ST-36 like that.Viewing area C2 extended (picture 3,4) under the unusual situation for example taken place in right heater coil 6R.If being judged as which heater block is not that (all be in according to heater block stop in learning) takes place under the unusual situation, for example under the temperature anomaly of central authorities' demonstration/input part 80 rises such situation, the enlarged areas of viewing area F to several times, and is expressed unusual content (with reference to ST-37, picture 2) in this district.

After state that viewing area C2 is extended has been kept the time that the user can fully realize (for example several branches back), the picture that automatically turns back to original district's area shows, shows that with red glyphs etc. the warning of " high temperature abnormality " and so on shows like that under the title of the unusual right heater coil 6R that takes place shown in picture 4.In addition, also can not automatically to turn back to this picture 4, but fully confirm, and carry out making picture turn back to original state under the situation of acknowledgement key operation the user.

Perhaps, can also with the user can Visual Confirmation speed (stipulated time) carry out the switching of picture 4 and picture 5 at interval, picture is shown with interactive mode.Carry out this demonstration in that viewing area E is capable, the message that the attention that is used to allow the user correct abnormality is aroused or assisted, asks to confirm.In the example of picture 4,5, do not called attention to by the rear of obstruction such as cooking appliance or suction hole 375 (Fig. 3 with reference to) with the mode that cloth or other things stop up with the top of the exhaust outlet 74,75 (with reference to Fig. 1) of body.

Secondly, for being judged as can correct unusually unusual, execute exception is corrected and is handled in ST-39.For example, become under the situation of abnormal high temperature circuit for controlling electricity turning and send in the following sequence and correct instruction being judged to be right heater coil 6R.

1) increase for the rotating speed that makes heat coil to right heater block carry out the cooling fan 262 of air cooling and to be in the cooling fan 261 of its upstream side, and when making its energising amount with usual running relatively and (for example 5%) increase, cooling air quantity is increased.Even if this state is being continued also not occur improving under the situation of effect in 1 minute, then

2) firepower (power) (setting from the user) with right heater block reduces.For example, within the firepower under 1 grade, firepower or this three of firepower of 10% under the 300W, make it drop to maximum firepower (under situation about using, dropping to 2.7KW) with the 3KW firepower.In addition, as picture 5 on the C2 of viewing area advance notice show firepower automatically descended (in addition, to handle also be effective countermeasure repeatedly for several times though this firepower descended, and for the convenience on illustrating, just only the disposition that descends of 1 firepower describes).

(among right heater coil 6R, take place unusual in short time with interior from the state of picture 4 or picture 5, the extended moment of viewing area C2 rises, in for example 1 minute～3 minutes), in order to confirm whether the high temperature abnormality is eliminated, circuit for controlling electricity turning 200 is judged once more and is had or not (ST-40) unusually.

In addition, because temperature detection self was carried out every the several seconds, circuit for controlling electricity turning 200 is all judged having or not unusually at any time again, so even if the detected temperatures that becomes the temperature sensor of set point of temperature (for example, 300 ℃) or liquid crystal display part 1 fen detected temperatures with the temperature sensor S2 of interior, right heater coil 6R becomes under the situation of set point of temperature (for example 70 ℃), circuit for controlling electricity turning 200 also by this determination processing again (ST-40) that has or not unusually, is judged to be " precarious position " (ST-41).

Under the situation of the judgement of having carried out abnormality, be presented at once on picture 6 or the picture 7, stop the energising (ST-42) of right heater coil 6R like this.

Watch picture 6 or picture 7, picture 8 if become the user for this reason, just can easily understand because of the temperature anomaly self-braking state that rises.

In determination processing (ST-40A) again, only otherwise be judged to be in ST-26～32 of returning at Figure 21 that (for example, the temperature less than of right heater coil 6R is 280 ℃ below the unusual determinating reference value, the temperature of central authorities' demonstration/input part 80 is below 49 ℃ again), just do not make it return to normal cooking action (normal cooking mode, ST-21 with reference to Figure 21), repeatedly processing is turned back to again the ST-40 of determination processing.Be judged to be under the situation about returning to below the determinating reference value, returning the ST-21 of Figure 20, after, heater block anomaly monitoring and body anomaly monitoring shown in Figure 21 proceed in the cooking.

In addition, send the energising halt instruction of right heater coil 6R, the energising of right heater block is stopped (ST-44).

But, the cooling fan 262 that cools off the heat coil of this heater block also remain in operation afterwards 2 minutes～5 minutes (but, detecting from the abnormal current etc. that cools off fan 262, distinguishing is under the situation of fault of cooling fan self, also stops simultaneously to the energising of this cooling fan.In addition, the conditions such as size of the running firepower of situation that this running continuation time and the temperature that stops up to energising rise and indoor air temperature, heater block are corresponding, determined according to predetermined computing formula and numerical tabular by circuit for controlling electricity turning 200).

Right thus heater coil 6R just swashs acute ground temperature rising and so on after the air-supply from cooling fan 262 has just stopped overshooting problem also can possibly prevent.In addition, can also prevent the disadvantage that the temperature of central authorities' demonstration/input part 80 uprises and so on.

On the other hand, in the use of right heater coil 6R, under the situation that central heater block 7 is also using, cooling fan 315 is also turning round in cooling fan 262 runnings, even if so stop the energising of right heater coil 6R in the case, cooling fan 262 also makes running continue.

This is because the characteristics of central as shown in Figure 2 heater block 7 are to become high temperature in the energising beginning back short time, so if these heater block 7 ambient airs are still uncolled, then the rear portion of superjacent air space 275 and top board 5 become the cause of high temperature.But, different with right heater coil 6R with the situation that strong firepower (for example 3KW) uses, because right heater coil 6R stops heating, proceed so be in to turn round a little less than the running of the cooling fan 262 in left side is switched to.

In addition, also be in right heater coil 6R with cooling fan 262 synchronous operated cooling fans 261 and be stopped energising, constitute the athermic situation of electric component 371R oneself of its power unit, so automatically switched to weak running.

On the E of boot section, show the information that becomes reference for key operation simultaneously with it.For example, wanting to set under 25 minutes the situation, in the moment that becomes " 25 " picture, as long as press the corresponding function key 98 of the display key suitable with decision key 103, change is specified to 25 fens, and also automatically changed with this time after changing remaining time.

For example, if above-mentioned time change is carried out rapidly, then the demonstration of 10 minutes remaining times and so on is altered to 15 fens and is shown as " also change remaining time " (state of picture 12).Like that, the area of the viewing area A2 of left heater coil 6L automatically enlarges greatlyyer in order to allow the user can easily cook the affirmation of time and input shown in picture 11.

In addition, taking place under the state that any heater block all is failure to actuate under the situation of precarious position, like that, for example the liquid crystal panel at central authorities' demonstration/input part 80 partly becomes under the situation of abnormal high temperature, carries out " whether PLSCONFM high temperature pot is placed on the top board shown in picture 2.PLSCONFM adds the pot of pining for central heater and whether is in the position of regulation " etc. attention arouse (ST-43).

Then, circuit for controlling electricity turning 200 switches to pre-stand-by power source 400 with power supply, and source power supply 202 is cut off (ST-53).

And then abnormal show continues automatically to stop the driving of central authorities' demonstration/input part 80 afterwards, the demonstration (ST-47) of turning off liquid crystal panel through certain hour.
