Front side one end (equipment for steam treatment 20 sides described later) at above-mentioned pipeline 7 is fixed with seal member 9, and sealing parts 9 are formed by silicon compound rubber etc., is used to avoid steam to produce between mouthful 6a and the steam passage 7A from steam and is leaked to the outside.
In addition, at pipeline 7 midway, be formed be used to stop the effluent (blowing out thing) beyond the steam and make its return in effluent of pot 2 send portion's (お ね ば returns) 8 back to.It is the summit that the bottom surface 7B that is formed at the steam passage 7A of pipeline 7 inside sends portion 8 back to effluent, towards each other end at the direction that descends tilt (with reference to Fig. 4).Send portion 8 back to by this effluent, emit, also can stop this effluent, prevent that it from going out to equipment for steam treatment 20 effluents from pipeline 7 even the effluent beyond the steam produces a mouthful 6a from steam.The maximum stream area of section that this effluent is sent the upstream portion of portion back to is about 4.9 square centimeters, and (bore of horizontal direction is
Flowing path section), effluent send back to portion 8 directly over the part be the narrowest position (restriction), its flow path cross sectional area is about 1.4 square centimeters (high 7.5mm * wide 19.0mm).
Equipment for steam treatment 20 has: water tank 21, this water tank 21 can be stored the water that is used to carry out steam treatment (carrying out condensation process to produce mouthful steam of 6a discharge from steam in equipment for steam treatment); Case lid 22, these case lid 22 freely openable ground cover the upper surface open portion of water tank 21; Trumpet-shaped noise reduction parts 23, the condensation sound that these noise reduction parts 23 produce when being used to alleviate steam treatment; Case cover 24, this case cover 24 forms in the mode of the outward appearance portion of covering water tank 21, and freely is fixed in water tank 21 with loading and unloading; Sealing plate 25, sealing plate 25 play the water avoided in the water tank 21 etc. leaks into outside two-fold lid from the part of case lid 22 effect; Check valve (not shown), this check valve be used to prevent the water of condensation in water tank 21 turn back in pot 2; Communicating pipe 26 described later.
Any one of above-mentioned water tank 21, case lid 22, noise reduction parts 23, case cover 24 and communicating pipe 26 all formed by processing and forming by plastic components.
At the lower surface of case lid 22, the communicating pipe 26 in connecting pipe 7 and the water tank 21 lower surface from case lid 22 vertically extend setting downwards by one-body molded processing.In addition, above-mentioned noise reduction parts 23 are fixed in the lower end outer peripheral face of this communicating pipe 26 by embedding mechanism.And the bore of this communicating pipe 26 begins in entire scope basic identical from the upper end, removes the Embedded Division of the noise reduction parts 23 of bottom, and the bore of other parts is about 17mm * 17mm, and therefore, flow path cross sectional area is about 2.89 square centimeters.
Consider the relation of the size (highly) of the length of vertical direction of communicating pipe 26 and case 21 as follows, promptly, with case lid 22 closures during in water tank 21, the lower ending opening 23a of noise reduction parts 23 that is fixed in the lower end of communicating pipe 26 is arranged in the position of water surface certain depth (H) that distance is stored in the water of water tank 21.This be because, if the lower ending opening 23a that sets noise reduction parts 23 does not irrelevantly have the degree of depth with respect to the water of water tank 21, under than the situation that needs depth as shallow, because the steam of emitting from lower ending opening 23a and water tank 21 interior water are fully contacted, the steam come-up also is discarded in the atmosphere, thereby causes steam treatment bad.
Therefore, above-mentioned certain depth location (H) is set as follows, promptly, even under the situation of heating source 4 with the maximum fire energising, also can condensation produce the whole steam that mouthful 6a produces from steam, specifically, by the speed that blows afloat and the steam cooling of vapor bubbles and become the speed decision of water.In the present embodiment, to be set at the scope with 80mm～90mm be permissible value (this permissible value is managed effectively by aftermentioned water sensor 48 and level sensor 47) to the degree of depth.In addition, said herein " steam " be meant, in aftermentioned is cooked the operation and the operation of cooking rice over a slow fire, interior pot 2 inner that produce, by the steam of pipeline 7 from communicating pipe 26 guiding, in the present embodiment, can reclaim " suction operation "～steam of " insulation operation ".In addition, the insulation operation is meant, in the present embodiment, finishes till back 8 hours to " operation of cooking rice over a slow fire ", and length that still should the time can appropriate change.
In addition, above-mentioned check valve is arranged on the top of communicating pipe 26 and is arranged on and is not immersed in the position that is stored in the water in the water tank 21, has following effect, promptly, when reducing (finishing the back in the cook operation and the operation of cooking rice over a slow fire takes place) from the air pressure of interior pot 2 between steam passage 7, the valve body of check valve is opened the valve port that sucks ambient atmos naturally by pressure differential, and by sucking extraneous air, the air pressure in making in the pot 2 reverts to atmospheric pressure.The adverse current phenomenon that can stop thus, the extremely interior pot 2 of water sucking-off in the water tank 21.
In addition, by case cover 24 is fixed in water tank 21, even the water of steam treatment rear water box 21 inside becomes high temperature, can be not yet with scalding contact equipment for steam treatment 20 (and, water tank 21 designs as follows, that is, and and in cooking and the time point that finishes of cooking, can not reach the high temperature of scald, this point is narrated in the back).In addition, at the upper surface of case lid 22, be formed with a plurality of small-bore passages 27.22A is the opening that is formed at case lid 22, is the upper end open of above-mentioned communicating pipe 26.Under the state of the above-mentioned lid 3 of closure, the seal member 9 of above-mentioned pipeline 7 is in the mode of the mouth edge part that surrounds above-mentioned opening 22A and with the contact of the state of close attachment, and the steam passage 7A of pipeline 7 is not communicated with the outside halfway and is communicated to the inside of communicating pipe 26 effectively.
In addition, as shown in Figure 5, equipment for steam treatment 20 is installed on the front part of the base plate 33 of the bottom surface that constitutes main body 1 with freely loading and unloading by inserted structures such as for example pawls.Thus, when dress water in water tank 21, whole equipment for steam treatment 20 can be taken off from main body 1, directly take water supply pipe tap place.That is, under the state of opening lid 3, lift water tank 21 upward and self just can take off from main body 1 simply, and if take off case lid 22, communicating pipe 26, water tank 21 inside also can be cleaned simply from needless to say, spatter property is good.
In addition, water tank 21 rear side of equipment for steam treatment 20 with the gabarit front surface of main body 1 between keep the relative mode mounting in minim gap ground below 1～2mm in the base plate 33 of main body 1.That is, water tank 21 is removed tripartite outside the part (back side) relative with the front surface 1A of aforementioned body 1 and is all contacted (being actually the structure that contacts room airs via above-mentioned case cover 24) with room air.Thus, we can say that water tank 21 self is the structure of easy natural heat release, and water tank 21 back sides are difficult to from main body 1 directly be conducted heat, and are difficult to conversely transmit heat to main body 1.
The 34th, be installed on the box workbin of the rear side of main body 1, the lower end mounting is accommodated the linkage that contains above-mentioned pivot fulcrum 31 in above-mentioned base plate 33 in upper inner.The 35th, be accommodated in the control substrate in this workbin, be that the printing wiring substrate of the load coil of above-mentioned heating source 4 being supplied with the translation circuit of the RF power of stipulating is installed.In addition, here said " translation circuit " is by resonating capacitor, becomes the circuit of the electric power control of switching mechanism with formations such as semiconductor (IGBT etc.), the drive circuit that drives this switching mechanism, smoothing capacitor, inertia diodes, wherein, above-mentioned resonating capacitor is by the driven by power of the rectifier bridge connection circuit of the bus that is connected in source power supply from input side.The 36th, the aluminum radiating fin of the part, for example power semiconductor etc. of the heating in the constituent part in the above-mentioned translation circuit is installed, this fin in the course of work of cooking device always by being arranged at the small-sized axial flow type fan coolling of workbin 34 inside.In addition, on this control substrate 35, the various electric parts of aftermentioned controlling organization 40 are installed.
Next, be that the center describes controlling organization 40 with Fig. 7.
Controlling organization 40 is made of power supply unit 41 and control part 42.Control part 42 is that the center constitutes with one or more microcomputer.This microcomputer is made of this four part of input part, efferent, storage part and CPU (calculating control part), and be supplied to dc source via above-mentioned power supply unit 42, realize central role of the indication mechanism 43 that control is made of heating source 4 and liquid crystal display substrate 30.In this control part 42, operation condition as heating source 4, respectively the correlation graph of the temperature of pot temperature of 2 bottom surfaces and rice in the storage, respectively cook menu (rice, do not have the selection of washing rice, " common " of the degree of cooking, " hard slightly ", and with cook usually different " congee ").In addition, as the operation of cooking, stored the control program of carrying out " preheating procedure ", " operation of cooking ", " operation of cooking rice over a slow fire " and " insulation operation " these four operations in turn.In addition, as one of said " operation condition " here, power on condition is arranged, and this power on condition is meant the condition of the electric and physics of heating source 4, is the general name of the conduction time, energising amount, powered-on mode (energising continuously, be interrupted energising, current on time etc.) etc. of heating source 4.
The 44th, temperature testing organization, the bottom surface of pot 2 in being crimped on from the below by compression spring etc., the temperature of the bottom of a pan face is also exported this detection signal in detecting, and uses thermistor temperature sensor.The 45th, be arranged at the operating mechanism of the lid 3 upper surface front parts of aforementioned body 1, be formed at a plurality of keys of push type on the surface of lid 2 by operation, can set the operation condition of heating source 4.In addition, aforesaid operations is disposed at the part nearby of display window with key, above-mentioned display window be formed in the mode of the input results that can confirm this key above-mentioned indication mechanism 43 liquid crystal display substrate 30 directly over.
The 46th, by the time movement that timer etc. constitutes, the timing signal of its output is imported above-mentioned control part 42 and to above-mentioned indication mechanism 43 output present moments with time information is set, so those are presented on the liquid crystal display picture of indication mechanism 43 constantly.
The 47th, be stored in the level sensor of the amount of the water in the above-mentioned water tank 21 by water level detecting, hold the water of water tank 21 by light, weight and other physical condition, be arranged at the part relative, perhaps be arranged at the front part upper surface of the base plate 33 that loads water tank 21 with the water tank 21 of the front part of main body 1.
The 48th, detection is stored in the cooling-water temperature sensor of the temperature of the water in the above-mentioned water tank 21, to detect the mode of water temperature via the sidewall of water tank 21, be arranged at the part relative of the front part of main body 1, perhaps be arranged at the front part upper surface of the base plate 33 of loading water tank 21 shown in Figure 5 with water tank 21.
Below, the action of equipment for steam treatment 20 is described.
The cooking device of present embodiment (cooker) is storage control program in above-mentioned control part 42, thereby carries out preheating procedure in turn, the operation of cooking, the operation of cooking rice over a slow fire and these four operations of insulation operation.At first, take off the case lid 22 of the water tank 21 that takes off from main body 1, to water tank 21, add water from the outside.Then, inwardly add the water and the rice of ormal weights in the pot 2, push the start button of cooking (key) of lid 3 upper surfaces that are positioned at main body 1 and begin to cook.Thus, heating source 4 is heated and cooks.The representative operation of cooking is represented in Fig. 6.
In Fig. 6, in preheating procedure, heating source 4 begins energising with the continuous powered-on mode of strong firepower at first, pot 2 temperature inside are when reaching the temperature (55 ℃) of regulation in temperature testing organization 44 detects, and this information is imported into control part 42, suppress the energising amount in the mode of keeping 55 ℃, in addition, because be intermittently power-on, there is not steam to produce substantially, do not carry out steam treatment yet.To keep this more than state continuance certain hour of 55 ℃ (time movement 46 calculates the elapsed time that begins from the time point that reaches 55 ℃, and this timing signal is imported above-mentioned control part 42, thereby the concluding time of control preheating procedure).
Next, when entering when cooking operation, the firepower grow of heating source 4, the water temperatures in the interior pot 2 rise gradually, and the water in the interior pot 2 reach boiling.When boiling aggravation and quantity of steam increase, the pressure in the interior pot 2 is compared atmospheric pressure and is raise, and the steam that produces in interior pot 2 is pushed out by this pressure,, flows in the equipment for steam treatment 20 by steam passage 7 from steam generation mouthful 6a.At this moment, because steam produces between mouthful 6a and the steam passage 7 and sealing such as sealed parts 9 between steam passage 7 and the case lid 22, steam can not be leaked to the outside.In addition, the bore that steam produces mouthful 6a is set at following size in advance, promptly, no matter be under the situation that heating source 4 is cooked with the minimum amount of cooking of regulation or carrying out with maximum fire 1400w under the situation of cooking that the maximum amount of cooking 5.5 closes, can both limit the discharge of the steam of generation, the air pressure state higher in can keeping in the pot 2 than atmospheric pressure.By the action of cooking at the appointed time under this pressure state, meal is delicious more.
Then, flow into steam in the equipment for steam treatment 20 by communicating pipe 26 and from the lower ending opening 23a of noise reduction parts 23 is ejected to water in the water tank 21.Then, the steam of ejection contacts with water tank 21 interior water, and heat is seized and dewfall by water, recover into water.
Like this, steam obtains handling, thus the steam leakage that prevents to produce from interior pot 2 to the outside, the increase of undesirable moisture in the time of can preventing cooking.
Then, become again in water tank 21 and be water because flow into steam in the equipment for steam treatment 20, so along with the propelling of the operation of cooking, the water yields in the water tank 21 increase gradually, water level also slowly rises.Here, because be provided with passage 27 on case lid 22, so the air of the amount that increases is discarded to the outside by passage 27, the pressure in the steam treatment process in the equipment for steam treatment 20 can not rise, and can successfully carry out steam treatment.
Then, from the time point midway of the operation of cooking (this time point is to observe from the elapsed time that the time point that reaches fluidized state begins by above-mentioned control part 42 to realize) beginning, the firepower of heating source 4 dies down, when finishing, the water of water vapourization and interior pot 2 inside that emit tails off, and interior pot 2 internal temperatures rise to about 130 ℃ rapidly from the state a little more than 100 ℃ before.Like this, said temperature testing agency 44 detects this rapid temperature rises, and by temperature detection information is input to control part 42, control part 42 is judged the end of cooking.
Like this, when enter the operation and when proceeding to cook of cooking rice over a slow fire from this stage, along with the process of time, the steam generation slowly reduces, and when finishing when cooking, cooling and pressure descend in the interior pot 2.Thus, the same pressure of steam passage 7A reduces, and the water in the water tank 21 begins to be drawn from the lower ending opening 23a of noise reduction parts 23.After beginning this absorption, check valve (not shown) is opened, and sucks extraneous air from passage 27, thereby the pressure in the interior pot 2 returns to the original state approaching with atmospheric pressure.
In addition, the quantity of steam that produces in though cook can be according to the combination of the kind of rice (rice, do not have and wash rice etc.), the method for cooking (sticking slightly firmly, slightly), menu (common cook, congee) etc. and difference, but in either event, water capacity in the water tank is all set as follows, promptly, carry out steam treatment in the process before finishing this cooking menu effectively, the water temperatures in the water tank 21 after finishing of cooking are the temperature that can not scald, for example below 55 ℃.
As mentioned above, steam mainly produces in the cook operation and the operation of cooking rice over a slow fire, therefore, in embodiments of the present invention, determine the quantity of steam of in these operations, emitting by calculate and experiment etc., and set the water yield of water tank 21 and water level (this has determined the condition of the position that sprays by communicating pipe 26 from the water of lower ending opening 23a to water tank 21 in of noise reduction parts 23, so important).Can recognize: even the sufficient water yield is arranged, if the shallow position in water is ejected in the water steam, fully under the state of contact, steam keeps the rising of blister ground and is discarded to the atmosphere from the water surface at steam and water.Therefore, in the present embodiment, by level sensor 47, before the initial suction operation of the operation of cooking began, whether the water yield that above-mentioned control part 42 carries out water tank 21 inside according to the detection information of level sensor 47 was judged fully.
Promptly, the position of the lower end of the communicating pipe of having fixed 26 is positioned at how dark position and is determined by water level in water, therefore, be used to determine the water yield of this water level, carry out the finally whether judgement in the scope of 80mm～90mm of the degree of depth in the water of lower end of communicating pipe 26 by detection.Therefore, the mechanism of sensed water level can detect the position of the water surface by light, and perhaps the mode that moves up and down with the change along with water level is floated float and detected its position, perhaps measures the gross weight of water.In addition, under the situation of the unnecessary water that has the upper limit water level that surpasses 90mm, above-mentioned control part 42 also can not begin the energising of heating source 4.This be imagination by condensation turn into and the water that reclaims causes water level to raise and the measure taked turns into causing water to overflow in water tank 21 to prevent condensation.
And, not having under the situation that can turn into by condensation with the water level that reclaims the steam that produces, above-mentioned control part 42 can not begin the energising of heating source 4.And, simultaneously, will notify the user (also can report) by indication mechanism 43 owing to the descend situation that causes water shortage and of water level in order to make the beginning of cooking wish the information of supplementing water with sound.
In addition, because have the cooling-water temperature sensor 48 that detects the temperature that is stored in the water in the above-mentioned water tank, by the output of this cooling-water temperature sensor, above-mentioned control part 42 can judge that whether the temperature of the water in the water tank 21 is than set point of temperature height.Under unusual high situation, above-mentioned control part 42 can not carried out the action that begins to switch on to heating source 4, and preheating procedure can not carried out yet.
In addition, the control program of above-mentioned control part 42 is set as follows, promptly, in case after entering the operation of cooking, before the end of cooking, the water temperature of above-mentioned water tank 21 is in the temperature range of regulation, even make the water temperature of above-mentioned water tank become than set point of temperature under the high situation (for example the room temperature that the space is set of cooking device situation about sharply rising) for some reason, cooling-water temperature sensor can detect this variation, in this case, above-mentioned control part 42 changes the power on condition of heating source 4, and carries out the action that weakens actual firepower.But the degree that this firepower suppresses is carried out in not hindering the original scope of cooking action, boiling.In addition, as the method that weakens firepower, can use suitable methods such as reducing supply capability amount self and reduction current on time.In addition, in present embodiment 1, cooking when beginning, the action that begins to cook under water temperature is situation below 35 ℃ is not entering the operation of cooking above under 35 ℃ the situation.This is to consider when cooking end to make the temperature of the water temperature of water tank 21 can not reach the abnormal high temperature zone.
