Below, with reference to Fig. 3, the action of the electric cooker of this first embodiment is described.Fig. 3 means the variations in temperature of pot of the operation of cooking and the figure of the driving condition of heater (pot heater 5 and inner cap heater 10).

First, by user, in pot 2, put into meter He Shui, utilize operating portion 19 to select to cook after menu, when beginning is cooked in indication, according to the control of control part 7, start the operation of cooking.

At this, what is called cook operation refer to by take precooking process (also referred to as soaking operation), heating process (also referred to as the operation of heating), maintain boiling operation, stewing operation processed is four main operations formations.During these operations, promote the gelatinization (thickness) of rice and rice is cooked into meal.This operation of cooking,, is controlled the pot heating action of pot heater 5 and inner cap heater 10 and carries out according to the detected temperatures of pot temperature sensor 6 and inner cap temperature sensor 9 and corresponding to the program of cooking of the menu of cooking by control part 7.In this first embodiment, according to the preparations such as kind of rice, there are a plurality of menus of cooking, the program of cooking of the menu of cooking corresponding to this each is stored in control part 7.

When the operation of cooking starts, first start precooking process.Precooking process is water to be remained on to certain temperature make rice absorb the operation of moisture.In this precooking process, control part 7 is according to the detected temperatures of pot temperature sensor 6 or inner cap temperature sensor 9, control pot heater 5 and inner cap heater 10, to control more than temperature that the temperature of pot 2 makes the water in pot 2 can not reach the temperature (approximately 60 ℃) that rice starts gelatinization.Thus, promote rice to absorb moisture.

From precooking process, start to proceed to heating process after the predefined time.Heating process be by pot heater 5 and inner cap heater 10 without a break by pot 2 heating, make water in pot 2 become the operation of fluidized state (approximately 100 ℃).In this heating process, control part 7 is controlled the driving of pot heater 5 and inner cap heater 10, so that heating kettle 2 makes the water in pot 2 become fluidized state hastily.

By implementing heating process, when the detected temperatures of pot temperature sensor 6 becomes approximately 100 ℃, be transferred to and maintain boiling operation.Maintaining boiling operation is the starch gelatinization that makes rice, makes gelatinization degree be increased to the operation of 50%～60% left and right.At this, maintain in boiling operation, control part 7 is controlled pot heater 5 and inner cap heater 10, to maintain the fluidized state of the water in pot 2.More particularly, the control part 15 of cooking carry out with certain hour interval repeatedly pot heater 5 and inner cap heater 10 driving, drive the dutycycle (duty) stopping to control, intermittent-heating pot 2.

In this heating process, owing to making continuously water boiling, so the steam of approximately 100 ℃ produces in large quantities.While being full of in the steam of this generation makes pot 2, unnecessary steam flows in air-supply paths 15 by steam passage 16.At this moment, control part 7 detects by pot temperature sensor 6 situation that the water that takes the dish out of the pot in 2 has seethed with excitement, starts to drive air-supply arrangement 11.Thus, air-supply arrangement 11 sucks extraneous gas from air entry 12, and this extraneous gas is blown to exhaust outlet 13 (direction of the arrow B in Fig. 2).From steam passage 16, flow into the above-mentioned steam of air-supply path 15, and the extraneous gas of being blown by this air-supply arrangement 11 is in the interior mixing of air-supply path 15.The fluid-mixing of this extraneous gas and steam, by the wind-force of air-supply arrangement 11, is expelled to the outside of electric cooker by the exhaust outlet 13 from lid main body 3.For example, due to steam (approximately 100 ℃) and extraneous gas (approximately 25 ℃) are mixed, so can make the temperature of discharged fluid-mixing lower than the temperature of steam.

In addition, in this first embodiment, steam passage 16 is connected with a part for the bottom (bottom surface) of air-supply path 15, because steam and extraneous gas are in a ratio of high temperature, so lighter, be moved upward to the steam natural of therefore discharging from steam passage 16, be easy to mix with extraneous gas equably in air-supply path 15.

The fluid-mixing of discharging from exhaust outlet 13 is tilted face 14a restriction, make its according to the inside along with from lid main body 3 to outside and flow away from the mode of hinge axis A.At this moment, in the time of in electric cooker is arranged on the shelf C surrounding with shelf with outside except the place ahead, the fluid-mixing of discharging from exhaust outlet 13, as shown in Figure 2, mobile to the direction of arrow B 1 along the sidewall of shelf C.Thus, prevent that fluid-mixing is detained in shelf C, can prevent shelf absorbing moisture and the undesirable conditions such as expansion.In addition, owing to can preventing that electric cooker temperature around from rising, so for example, can suppress the rise action that causes of temperature because of the parts of control part 7 unstable etc.

By maintaining the enforcement of boiling operation, when the most of moisture in pot 2 disappears, more than the temperature in pot 2 rises to the boiling point of water.For example, when pot temperature sensor 6 detects the temperature of pot in 2 and reaches the boiling point above (approximately 130 ℃) of water, be transferred to and boil in a covered pot over a slow fire operation processed.Stewing operation processed is to utilize preheating to make unnecessary moisture evaporation, improves the gelatinization degree of rice to the operation that approaches 100%.In this stewing operation processed, the temperature of pot 2 drops to below uniform temperature each time, and control part 7 is controlled pot heater 5 and inner cap heater 10, to pot 2 is heated.More particularly, control part 7 with maintain boiling operation similarly, carry out with certain hour interval repeatedly pot heater 5 and inner cap heater 10 driving, drive the dutycycle (duty) stopping to control, intermittent-heating pot 2.In addition, in this stewing operation processed, owing to only discharging some steam from steam passage 16, thus control part 7 so that the mode that air-supply arrangement 11 continues drivings control.

From starting after the predefined time of stewing operation processed, stewing operation processed (being that whole operations of cooking finishes) finishes, and is automatically transferred to insulation operation.

In addition, in foregoing, when maintaining the beginning of boiling operation, the driving of putting in blast device 11, but the present invention is not limited to this.For example, although in heating process amount seldom only, also still produce steam (hot gas), therefore, driving that also can putting in blast device 11 in heating process process.In addition, because the steam at this moment producing is lower and amount is also few than the vapor (steam) temperature producing in maintaining boiling operation, so there is no need to make air-supply arrangement 11 drivings.

(the second embodiment)

Use Fig. 4 to describe the electric cooker of second embodiment of the invention.Fig. 4 is local excision's top view of the electric cooker of second embodiment of the invention.The difference of this electric cooker of the second embodiment and the electric cooker of above-mentioned the first embodiment, near exhaust outlet 13, also possesses containment wall 14b, exhaust channel the place ahead expansion wall 14c.In this second embodiment, by inclined plane 14a, containment wall 14b and exhaust channel the place ahead expansion wall 14c, formed an example of discharge directions limiting unit.

As shown in Figure 4, containment wall 14b is configured according to the mode that the part of the hinge axis A side of the through hole 13a of a plurality of slit-shaped of formation exhaust outlet 13 is stopped up.In addition, exhaust channel the place ahead expansion wall 14c be configured to by exhaust channel 15 away from hinge axis A mono-side and near wall exhaust outlet 13 more to expand away from the mode of hinge axis A.Sidewall being positioned at the lid main body 3 in the region of being expanded by this exhaust channel the place ahead expansion wall 14c, is formed with the through hole 13a of the same area with the through hole 13a being stopped up by containment wall 14b.In other words, exhaust outlet 13 is being configured in the direction of hinge axis A on the bias than air-supply path 15, containment wall 14b and exhaust channel the place ahead expansion wall 14c is according to the inside along with from lid main body 3 to outside and tilt or crooked away from the mode of hinge axis A, and the path 15 of blowing is connected with exhaust outlet 13.

In the electric cooker of this second embodiment, by exhaust channel 15, flow into the flowing of fluid-mixing of exhaust outlets 13, not only utilize inclined plane 14a but also utilize containment wall 14b and exhaust channel the place ahead expansion wall 14c is restricted to along with the inside from lid main body 3 is to outside and away from hinge axis A.Therefore, and only with inclined plane 14a, limit and compare, can make reliably the place ahead of the mobile trend electric cooker of fluid-mixing, and can guarantee air quantity.

By the electric cooker of this second embodiment, be accommodated in as shown in Figure 4 while cooking in shelf C, can make flowing of the fluid-mixing of discharging from exhaust outlet 13, the place ahead that do not reduce air quantity ground, tends to more reliably electric cooker.Therefore, can further suppress steam (fluid-mixing) and be detained in shelf C, can further suppress the undesirable condition of the unstable grade of action of the deteriorated and control part 7 of shelf.In addition, by being set, suppresses exhaust channel the place ahead expansion wall 14c the reduction of air quantity, so the cooling performance of steam can not decline.

(the 3rd embodiment)

Use Fig. 5 to describe the electric cooker of third embodiment of the invention.Fig. 5 is local excision's top view of the electric cooker of third embodiment of the invention.This 3rd enforcement electric cooker of formula point different with the electric cooker of above-mentioned the second embodiment is near the discharge directions guiding part 14d that possesses alternative inclined plane 14a and containment wall 14b exhaust outlet 13.In this 3rd embodiment, be by exhaust channel the place ahead expansion wall 14c and discharge directions guiding part 14d, to be formed an example of discharge directions limiting unit.

As shown in Figure 5, discharge directions guiding part 14d is the plate-shaped member arranging according to the mode that exhaust outlet 13 is divided into the through hole 13a of a plurality of slit-shaped.Being positioned near the part of a side of air-supply arrangement 11 of this discharge directions guiding part 14d is parallel with air-supply path 15, with the inside according to along with from lid main body to outside and tilt or crooked state is mounted away from the mode of hinge axis A.In addition, discharge directions guiding part 14d is designed to parallel with the thickness direction that covers main body 3 vertical direction of paper (in the Fig. 5 with respect to).In addition, in Fig. 5, represent to be provided with the example of two discharge directions guiding part 14d, at least arranged one above.

The end of one side of the close air-supply arrangement 11 of discharge directions guiding part 14d, is positioned at the side with the more close exhaust outlet 13 of part that is connected of air-supply path 15 than steam passage 16.In addition, the end of a side of the close air-supply arrangement 11 of discharge directions guiding part 14d, be preferably with respect to air-flow, reduce resistance shape as semi-circular section and wing section.The crushing that can produce when cutting apart air-flow by discharge directions guiding part 14d thus, is controlled at irreducible minimum.

In this 3rd embodiment, two the discharge directions guiding part 14d that flow through that flow into the fluid-mixing of exhaust outlets 13 by air-supply path 15 are divided into three strands and advance to exhaust outlet 13, and the inclination by discharge directions guiding part 14d or flexure plane are restricted to along with from lid main body 3 inside to outside and away from hinge axis A.Therefore, can suppress steam (fluid-mixing) and be detained in shelf C, can suppress the undesirable condition of the unstable grade of action of the deteriorated and control part 7 of shelf.In addition, in contrast, when there is no discharge directions guiding part 14d, near exhaust outlet 13, may produce the inequality of the pressure distribution of fluid-mixing.The inequality of this pressure distribution causes the crushing in the 15 interior generations of air-supply path, causes the reduction of air quantity.

According to the electric cooker of this 3rd embodiment, owing to possessing the mobile discharge directions guiding part 14d of cutting apart fluid-mixing, so the pressure distribution in the time of can being suppressed at the mobile restriction of fluid-mixing in air-supply path 15 is uneven.Thus, the reduction of air quantity can be suppressed to Min., can guarantee to greatest extent air quantity, and the discharge directions of fluid-mixing can be restricted to forwards to (below of Fig. 5).Therefore, can realize the cooling of steam and the delay that prevents the steam (fluid-mixing) in shelf C high-levelly simultaneously.

In addition, as shown in Figure 6, also can be at the lateral surface pipe laying 14e that covers the outer wall of main body 3.Thus, can be more reliably by the flow restriction of the fluid-mixing of discharging from exhaust outlet 13 for along with from lid main body 3 inside to outside away from hinge axis A.In addition, pipeline 14e is because be the flowing of the outside limits fluid-mixing of lid main body 3, so can not make the air quantity of the fluid-mixing of discharging from exhaust outlet 13 decline.Therefore, can be with the front part with respect to the approximately parallel angle configurations pipeline of exhaust outlet 13 14e (lower portion of Fig. 6).Thus, as shown in the arrow B 2 of Fig. 6, can make flowing in the mode that contact with the wall of shelf C towards the direction along covering the sidewall of main body 3 of the fluid-mixing of discharging from exhaust outlet 13.Thus, can further suppress steam is detained in shelf C.

(the 4th embodiment)

Use Fig. 7 and Fig. 8, the electric cooker of four embodiment of the invention is described.Fig. 7 and Fig. 8 are local excision's top views of the electric cooker of four embodiment of the invention.The different point of this electric cooker of the 4th embodiment and the electric cooker of above-mentioned the second embodiment is near exhaust outlet 13, to possess exhaust port area adjustment part 20 to substitute containment wall 14b.In this 4th embodiment, by inclined plane 14a and exhaust channel the place ahead expansion wall 14c and exhaust port area adjustment part 20, formed an example of discharge directions limiting unit.

As shown in Figure 7 and Figure 8, exhaust port area adjustment part 20 possess from the outstanding handle 20a of sidewall of lid main body 3 and along the medial surface of the sidewall of lid main body 3, can slide cover board 20b.User, by pinching handle 20a, makes to cover board 20b and slide, thereby plug blocks up the latter half (hinge axis A side) of exhaust outlet 13, can regulate the aperture area of exhaust outlet 13.

When exhaust port area adjustment part 20 is positioned at the position shown in Fig. 7, the aperture area of exhaust outlet 13 becomes maximum.The fluid-mixing of at this moment, discharging from exhaust outlet 13 is discharged from low wind speed.On the other hand, when exhaust port area adjustment part 20 is positioned at the position shown in Fig. 8, the aperture area of exhaust outlet 13 becomes minimum.The fluid-mixing of at this moment, discharging from exhaust outlet 13 is discharged from high wind speed.

Below, effect, the effect that for the aperture area of exhaust outlet 13, can regulate describe.

For example, when the electric cooker of above-mentioned the first embodiment is arranged in shelf C, the fluid-mixing of discharging from exhaust outlet 13 is as shown in Fig. 2 arrow B 1, and discharge in the place ahead along shelf to electric cooker.At this moment, because fluid-mixing contacts with shelf, at the wall of shelf, can generate a lot of dewfall.On the other hand, be contained in the quantity of steam of the fluid-mixing of discharging from exhaust outlet 13, so because the discharge reduction in the carrying out pot 2 along with the operation of cooking reduces.Specifically, comparison when being contained in the quantity of steam of the fluid-mixing of discharging from exhaust outlet 13 and maintaining boiling operation reduces when stewing operation processed.Therefore,, even the wall at shelf produces dewfall in maintaining boiling operation, also can in stewing operation processed, by the few fluid-mixing of steam amount, make it dry.

But, when stewing operation processed completes, likely do not make the situation of dewfall bone dry of the wall of shelf yet.In this case, according to said structure, because user can at random reduce the aperture area of exhaust outlet 13, so can strengthen the wind speed of the fluid-mixing of discharging from exhaust outlet 13, the rate of drying that can accelerate dewfall.On the other hand, while there is no shelf in the side of electric cooker, because user can expand the aperture area of exhaust outlet 13, so can weaken the wind speed of the fluid-mixing of discharging from exhaust outlet 13, the wind of the exhaust of can forgetting it and cooking.

In addition, in the above-described 4th embodiment, to stop up the mode of the latter half of exhaust outlet 13, form exhaust port area adjustment part 20, but the present invention is not limited to this.For example, exhaust port area adjustment part 20 also can be configured according to the mode of stopping up the bottom of exhaust outlet 13.At this moment, the fluid-mixing of discharging from exhaust outlet 13 mobile is restricted to along with the inside trend from lid main body 3 is outside and away from hinge axis A, and, be restricted to along with trend cover main body 3 thickness direction roof side and away from hinge axis A.That is the fluid-mixing of, discharging from exhaust outlet 13 mobile is restricted to towards the place ahead of electric cooker main body 1 and obliquely upward.

The effect, the effect that so form are commonly considered as described below.For example, it is generally acknowledged that it is not shelf that electric cooker is configured in its side, but have other the position of electronic product such as micro-wave oven.For example in micro-wave oven, its sidewall is provided with passage.Therefore,, when the fluid-mixing of discharging from exhaust outlet 13 enters the inside of micro-wave oven by this passage, can become at the internal condensation of micro-wave oven the reason of fault.When forming as mentioned above, can evade the fluid-mixing of discharging from exhaust outlet 13 and by this passage, enter the inside of micro-wave oven.

In addition, by the flow restriction of the fluid-mixing of being discharged by exhaust outlet 13, be that the place ahead of trend electric cooker main body 1 and being not limited to are obliquely upward used exhaust port area adjustment part 20.For example, use the pipeline 14e of above-mentioned the 3rd embodiment explanation also can carry out above-mentioned restriction.

(the 5th embodiment)

Use Fig. 9, the electric cooker of fifth embodiment of the invention is described.Fig. 9 is the sectional view of the electric cooker of fifth embodiment of the invention.The difference of this electric cooker of the 5th embodiment and the electric cooker of above-mentioned the first embodiment is at the medial surface that covers the roof of main body 3, to possess the extraneous gas temperature detecting part 21 of thermistor etc.

Extraneous gas temperature detecting part 21 detects the temperature of the roof of the lid main body 3 while starting of cooking, by its temperature information input control portion 7.The temperature of roof and the temperature extraneous gas temperature of electric cooker periphery of the lid main body 3 while starting of cooking are roughly the same.Control part 7, according to the temperature information by 21 inputs of extraneous gas temperature detecting part, is judged extraneous gas temperature (ambient temperature of electric cooker).For example, when extraneous gas temperature is 5 ℃～10 ℃, in the dewfall amount of the wall of shelf, increase, even cooking while finishing, at wall also easy residual water droplet.Therefore,, in this 5th embodiment, when externally gas temperature is for example, than predefined temperature (15 ℃) lower, control part 7 is controlled air-supply arrangement 11, makes air-supply arrangement 11 from the certain hour that remains in operation of having cooked.

According to the electric cooker of this 5th embodiment, when electric cooker being set in shelf C and cooking, externally gas temperature for example, than in the low situation of predefined temperature (15 ℃), from having cooked, make air-supply arrangement 11 certain hour (for example 10 minutes) that remains in operation, can fully make thus in the dewfall of the wall of shelf dry.Therefore, not affected by the environment for use temperature of electric cooker, and improve the performance of the Antidewing while cooking in shelf C.

In addition, the driving of air-supply arrangement 11 continues the time and predefined temperature needs only according at random settings such as the performances of air-supply arrangement 11.In addition, also can at length set according to extraneous gas temperature the continuation time of the driving of air-supply arrangement 11.

(the 6th embodiment)

Use Figure 10 and Figure 11, the electric cooker of sixth embodiment of the invention is described.Figure 10 means the sectional view that the electric cooker of sixth embodiment of the invention is arranged on to the state in shelf.Figure 11 is local excision's top view of the electric cooker of sixth embodiment of the invention.The difference of this electric cooker of the 6th embodiment and the electric cooker of above-mentioned the 5th embodiment is, the sidewall of alternative cover main body 3 and exhaust outlet 13 is set on roof, a near example that possesses discharge directions guidance part this exhaust outlet 13 is discharge directions guiding part 14f.Aspect is in addition identical, so mark prosign for identical structure when describing, the repetitive description thereof will be omitted.

As shown in figure 10, discharge directions guiding part 14f is the plate-shaped member arranging according to the mode that exhaust outlet 13 is divided into the through hole 13a of a plurality of slit-shaped.Discharge directions guiding part 14f is provided with at least more than one (in this case two) according to the mode of extending abreast with hinge axis A.In addition, the state that discharge directions guiding part 14f tilts away from the mode of hinge axis A with the inside trend outside (upward) according to along with from lid main body 3 is mounted.

Thus, flow into the flowing of fluid-mixing of exhaust outlets 13 by air-supply path 15, be deflated direction guiding parts 14f and cut apart and to exhaust outlet 13, advance, the inclined plane by discharge directions guiding part 14f is limited in the direction of arrow B 3 of Figure 10 simultaneously.Therefore, can suppress steam (fluid-mixing) and be detained in shelf C, can suppress the undesirable condition of the unstable grade of action of the deteriorated and control part 7 of shelf.In addition, even in the situation that the side of electric cooker is for example placed with micro-wave oven, due to exhaust outlet 13 is arranged on to roof, so also can evade the inside that the fluid-mixing of discharging from exhaust outlet 13 enters micro-wave oven.

In addition, in the face with hinge axis A quadrature, the angle θ that discharge directions guiding part 14f tilts with respect to the thickness direction (above-below direction in Figure 10) of lid main body 3 is preferably more than approximately 30 ° 90 ° of less thaies.When 30 ° of tilt angle theta less thaies, the mobile part of fluid-mixing of shelf that strikes the top of electric cooker is not the place ahead at electric cooker, but be likely turned back to, have the rear of mains cord (cord) etc. and is trapped in shelf C.In addition, in this case, be disposed at electric cooker rear mains cord near dewfall, likely cause the bad phenomenon such as tracking (tracking).

In addition, preferred angle θ be approximately 30 ° above below 40 °.When tilt angle theta is set in to approximately 40 °～90 °, because fluid-mixing flows in the position of the roof near lid main body 3, therefore, likely produce the bad phenomenon such as steam obfuscation in the mixed fluid of display surface of the display part 18 be arranged at the roof that covers main body 3.

In addition, in this 6th embodiment, the mode that discharge directions guiding part 14f is tilted according to the thickness direction with respect to lid main body 3 arranges, but also can arrange agley.In this case, the flexure plane of discharge directions guiding part 14f, the mode according to the flow direction of the fluid-mixing of discharging from exhaust outlet 13 with respect to the thickness direction inclination (preferably tilting with the more than 30 ° angle below 40 °) of lid main body 3 forms.

(the 7th embodiment)

Below, the electric cooker of seventh embodiment of the invention is described.Figure 12 is the sectional view of the electric cooker of seventh embodiment of the invention.Figure 13 is the functional block diagram of the electric cooker of seventh embodiment of the invention.The difference of this electric cooker of the 7th embodiment and the electric cooker of above-mentioned the 6th embodiment is also to possess air-supply control part 22.

In the prior art, in maintaining boiling operation and stewing operation processed, air-supply arrangement 11 is controlled drives (start and stop), makes it with certain wind-force, continue extraneous gas to blow.But in this case, what the high state of level of noise that the driving of air-supply arrangement 11 produces for example accounted for the time of cooking is bordering on half.The state that this level of noise is high continues for a long time, for example, if while utilizing timing function to make electric cooker action in the process of going to bed, become larger problem.

Therefore, the electric cooker of this 7th embodiment possesses air-supply control part 22, and it is judged by the amount of the steam of steam passage 16, and according to this result of determination, controls the wind-force (fan rotation number) of air-supply arrangement 11.Air-supply control part 22 is connected with control part 7, and is configured to and can controls air-supply arrangement 11 according to the control action of control part 7.Below, the decision method of amount and the wind control of air-supply arrangement 11 of the concrete above-mentioned steam based on air-supply control part 22 are described.

(according to the wind-force of controlling of the operation of cooking)

As illustrated in the above-described first embodiment, from the operation of the interior generation steam of pot 2, be mainly to maintain boiling operation.The generation of steam depends on the surplus of the water in pot 2, thus maximum in the first half term that maintains boiling operation, after this, reduce at leisure.More particularly, if maintain the approximately 15 minutes continuation time of boiling operation, maximum from the generation of beginning steam during 5 minutes that maintains boiling operation.On the other hand, in stewing operation processed, be the state that the most of moisture in pot 2 is absorbed or evaporated by rice, so if the generation of steam is more only little by little with maintaining boiling operation.Therefore,, according to the situation of carrying out of the operation of cooking, can judge by the amount of the steam of steam passage 16.

Therefore,, in this 7th embodiment, air-supply control part 22, according to the situation of carrying out of the operation of cooking, is judged by the amount of the steam of steam passage 16, and according to this result of determination, the wind-force of air-supply arrangement 11 is controlled.More preferably, air-supply control part 22 reduces at least one times the control of the wind-force of air-supply arrangement 11 in maintaining boiling operation, further reduces the control of the wind-force of air-supply arrangement 11 while being transferred to stewing operation processed.For example, air-supply control part 22 is set as 0.3m by the wind-force of air-supply arrangement 11 in the first half term (5 minutes) that maintains boiling operation ³, in the second half (10 minutes) that maintains boiling operation, the wind-force of air-supply arrangement 11 is set as to 0.25m ³, the wind-force of the air-supply arrangement 11 in stewing operation processed is set as 0.15m ³.Thus, the high state of level of noise can be controlled as only in the first half term that maintains boiling operation, can be than shortening significantly in prior art.In addition, consumes power can be reduced and only measures accordingly with making the reduction of the wind-force of air-supply arrangement 11.

(according to the menu control wind-force of cooking)

In addition, the amount of the steam of pot 2 interior generations is also different according to the menu of cooking.The what is called menu of cooking, represents the kind of rice of rice, clean rice, brown rice, congee etc. and the information of cooking way.For example the water absorption rate of rice and brown rice is different from absorption speed.Therefore,, according at the selected menu of cooking of operating portion 19, can judge by the amount of the steam of steam passage 16.

Therefore,, in this first embodiment, air-supply control part 22 according at the selected menu of cooking of operating portion 19, is judged by the amount of the steam of steam passage 16, and according to this result of determination, is controlled the wind-force of air-supply arrangement 11.The control part 22 of more preferably blowing is controlled, and makes in the situation that select menu that the generation of steam is few as the menu of cooking, than in the situation that select the many menus of generation of steam to reduce the wind-force of air-supply arrangement 11.Thus, because the generation of the different steam of menu of cooking is also considered, can control meticulously the wind-force of air-supply arrangement 11, can shorten significantly the state that level of noise is high than prior art.

(according to the Weight control wind-force that is cooked thing)

In addition, from the amount of the steam of pot 2 interior generations according to the rice of cooking to close number also different.The number that closes of the rice of cooking needs to add the water of pot 2 also more more.Therefore, by judging the rice that packs in pot 2 and the weight (being cooked the weight of thing) of water, thereby can judge by the amount of the steam of steam passage 16.

Therefore,, in this 7th embodiment, air-supply control part 22 is judged by the amount of the steam of steam passage 16 according to the weight that is cooked thing, is controlled the wind-force of air-supply arrangement 11 according to this result of determination.The control part 22 of more preferably blowing is controlled, and makes, in the situation that to be cooked the predefined weight of the weight ratio of thing little, to reduce the wind-force of air-supply arrangement 11.Thus, according to being cooked varying in weight of thing, the generation of different steam is also considered, and can control meticulously the wind-force of air-supply arrangement 11, can shorten significantly the state that level of noise is high than prior art.

In addition, as the detection method that is cooked the weight of thing, for example there is method as shown in figure 14, the example that weight detection unit is set is that weight sensor 23 is measured the weight that contains pot 2 integral body that are cooked thing, from this weight, deduct the weight of predefined pot 2, thus the method detecting.In addition, according to the weight that is cooked thing, in (making to be cooked the time of thing boiling) difference of needed time of heating process, so by measuring the needed time of heating process, also can detect the weight that is cooked thing.In addition, as weight sensor 23, can use known various forms of weight sensor all the time.Therefore, at this, omit the detailed description to the structure of weight sensor 23.

(according to boiling the number of times that overflow, controlling wind-force)

In addition, from the amount of the steam of pot 2 interior generations can according in pot 2 be cooked boiling of thing overflow number of times understand.That is, be cooked the boiling of thing of pot in 2 overflow and is to produce because of the amount of the water of pot 2 interior existence more.On the other hand, in maintaining boiling operation, as mentioned above, pot 2 by pot heater 5 and inner cap heater 10 by intermittent-heating.Therefore,, when the amount of the water of pot 2 interior existence is many, pot 2 is cooked the boiling of thing while being heated at every turn and overflows.That is, the amount of water of pot 2 interior existence is more, in pot 2 to be cooked the number of times that boiling of thing overflow just more.

Therefore,, in this 7th embodiment, air-supply control part 22 according to the number of times that overflow of boiling that is cooked thing in pot 2, is judged by the amount of the steam of steam passage 16, is controlled the wind-force of air-supply arrangement 11 according to this result of determination.Number of times the control part 22 of more preferably blowing overflows according to the boiling within a certain period of time of the beginning from maintaining boiling operation, controls the wind-force of the later air-supply arrangement of this certain hour 11.Thus, according to the amount of the steam by steam passage 16, can control meticulously the wind-force of air-supply arrangement 11, can shorten significantly the state that level of noise is high than prior art.

The detection method of in addition, boiling the number of times that overflow for example has method as shown in figure 14: utilize in an overflow example of number of times test section of boiling of steam passage 16 interior settings and boil the method that the sensor 24 that overflow detects.In addition, as boiling the sensor 24 that overflow, can use the known various forms of sensor that overflow of boiling all the time.Therefore, at this, omit boiling the detailed description of the structure of the sensor 24 that overflow.

(according to the pot heating action control wind-force of pot heater)

In addition, steam is when 5 pairs of pots 2 of pot heater heat from the interior main generation of pot 2.More particularly, at 5 pairs of pots of pot heater 2, carry out intermittent-heating and the temperature that is cooked thing in pot 2 is maintained to roughly certain maintaining in boiling operation and stewing operation processed, while being 5 driving of pot heater.Therefore, from the amount of the steam of pot 2 interior generations, can understand from the pot heating action of pot heater 5.

Therefore,, in this 7th embodiment, air-supply control part 22 is judged by the amount of the steam of steam passage 16 according to the pot heating action of pot heater 5, is controlled the wind-force of air-supply arrangement 11 according to this result of determination.More preferably blow control part 22 in maintaining at least one operation of boiling operation and stewing operation processed, according to the driving of pot heater 5, start and drive the moment stopping, making the wind-force increase and decrease of air-supply arrangement 11.Thus, except the time period that steam mainly produces, the wind-force of air-supply arrangement 11 is reduced, can shorten significantly the state that level of noise is high than prior art.

In addition, in this case, the moment that air-supply control part 22 also can make the driving beginning of pot heater 5 and the wind-force of air-supply arrangement 11 increase synchronizes, and makes the driving of pot heater 5 stop synchronizeing with the moment of the wind-force reduction of air-supply arrangement 11.In addition, steam in the moment starting due to the driving at pot heater 5 and pot 2 flowed between moment of air-supply path 15 has some time lags (time lag), so also can consider that these are former thereby determine to make moment of the wind-force increase and decrease of air-supply arrangement 11.In addition, air-supply control part 22 also can start and drive the moment stopping according to the driving of pot heater 5, and driving beginning and the driving of controlling air-supply arrangement 11 stop.Also can synchronize with the above-mentioned moment that similarly makes the driving beginning of pot heater 5 and the driving of air-supply arrangement 11 start in this case, the moment that the driving of pot heater 5 stops stopping with the driving of air-supply arrangement 11 is synchronizeed, also time lag can be counted and determine that these constantly.

In addition, in the process of cooking, in the place of the about 1m in the place ahead of electric cooker mensuration level of noise, the level of noise during driving of air-supply arrangement 11 is 38dB (decibel), and in contrast, the level of noise when driving of air-supply arrangement 11 stops is 32dB.That is, the time period not mainly being discharged from steam, the driving of out-of-blast device 11, can reduce 6dB by level of noise thus.

In addition, in maintaining boiling operation, when use starts the driving of pot heater 5 and drives moment of stopping, starts with the driving that makes air-supply arrangement 11 and drive electric cooker that moment of stopping synchronizes to cook, the wastage in bulk or weight electric weight of cooking while finishing is 215Wh.In addition, at this moment the rotation number of the fan of air-supply arrangement 11 is 3000rpm when the driving of pot heater 5, when the driving of pot heater 5 stops, is 0rpm.On the other hand, when use is cooked with the electric cooker of the prior art of the fan of the rotation number Continuous Drive air-supply arrangement 11 of 3000rpm, the wastage in bulk or weight electric weight while finishing of cooking is 220Wh.Known according to this measurement result, owing to the driving of pot heater 5 being started and driving moment of stopping, start with the driving of air-supply arrangement 11 and drive the moment stopping to synchronize, so can reduce than prior art the wastage in bulk or weight electric weight of 5Wh.

Above, utilize the electric cooker of this 7th embodiment, according to the amount of the steam by steam passage 16, control the wind-force (rotation number of fan) of air-supply arrangement 11 (specifically when passing through the amount of steam of steam passage 16 when fewer than predefined amount, reduce the wind-force of air-supply arrangement 11), therefore, the high time shorten of state continuance and the time of the above-mentioned wind-force of reduction of level of noise can be measured accordingly.In addition, can with the partial response that the wind-force of air-supply arrangement 11 is reduced reduce the amount of wastage in bulk or weight electric weight.

In addition, the judgement of the amount of above-mentioned steam at least according to carrying out, the menu of cooking of the operation of cooking, the weight that is cooked thing, the pot of boiling overflow number of times and pot heater, heat to move in any one, also can be according to all judging.At this moment, can judge more reliably the amount of above-mentioned steam, can control more meticulously the wind-force of air-supply arrangement 11, can shorten significantly the state that level of noise is high than prior art.

In addition, for the object of controlling the driving time of air-supply arrangement 11, also timing portion 17 (with reference to Figure 13) can be connected with air-supply control part 16.Thus, can or drive dwell time to control air-supply arrangement 11 according to predefined driving time.

(the 8th embodiment)

Below, the electric cooker of eighth embodiment of the invention is described.This electric cooker of the 8th embodiment and the difference of above-mentioned the 7th embodiment are, air-supply control part 22 is to control the wind-force of air-supply arrangement 11 according to the detected temperatures of extraneous gas temperature detection sensor 21, substitute according to the amount of the steam by steam passage 16, control the wind-force of air-supply arrangement 11.

From the steam of pot 2 interior generations as previously mentioned, the extraneous gas sucking with air-supply arrangement 11 mixes and discharges to outside.Therefore,, when extraneous gas temperature is high, the temperature of the fluid-mixing of discharging to outside raises.At this moment, the wind-force that strengthens air-supply arrangement 11 improves extraneous gas and accounts for the ratio of fluid-mixing, thereby can reduce the temperature of fluid-mixing.

Therefore,, in this 8th embodiment, air-supply control part 22 is controlled the wind-force of air-supply arrangement 11 according to the detected temperatures of extraneous gas temperature detection sensor 18.The control part 22 of more preferably blowing, when extraneous gas temperature is for example, than predefined temperature (15 ℃) lower, than when extraneous gas temperature being predefined temperature when above, reduces the wind-force of air-supply arrangement 11.Thus, can consider extraneous gas temperature and control meticulously the wind-force of air-supply arrangement 11, can shorten significantly the state that level of noise is high than prior art.

In addition, the present invention is not limited to the respective embodiments described above, can implement with other variety of way.For example, in the above-described 6th embodiment, as shown in figure 10, steam passage 16 is not linearity and be configured to and have bend, can prevent from directly invading in pot 2 by steam passage 16 from the extraneous gas of air-supply arrangement 11 air-supplies.When the extraneous gas invasion pot 2 from air-supply arrangement 11 air-supplies is interior, produce problem as described below.That is, in the operation of cooking, steam is to making rice absorb moisture in meter Jin Hang heating from the interior generation of pot 2, and the starch that makes rice is the operation (promoting the operation of gelatinization) of α state from β state variation.In this operation peripheral gas flows into pot 2 and water temperature while reducing, the gelatinization hindering meter, makes the taste deterioration of the meal made.In addition, in the above-described 6th embodiment, steam passage 16 is configured to has bend, but also so long as prevent from directly invading the structure in pot 2 from the extraneous gas of air-supply arrangement 11 air-supplies.For example, steam passage 16 also can be configured to and have expansion space portion.

In addition, by suitably combining the embodiment arbitrarily in above-mentioned various embodiment, can play the effect that had separately.

Ease of use when electric cooker of the present invention is the maximization that can suppress to cover main body, lid operation is good, and can under the state in shelf, can not damage shelf and cook electric cooker is disposed at, so be generally useful for electric cooker.

The present invention, describes for relevant preferred embodiment fully with reference to accompanying drawing, but have the knack of this technology everyone should understand various distortion and correction.This distortion and only revise otherwise depart from the scope of the present invention of the scope of the claim based on additional, is interpreted as being included in wherein.
