This thermatron 100 that has steam generating function is for being suitable for by coming heat treated to want the cooker of heated article to heating chamber 11 supply high frequency ripples (microwave) that hold article or steam at least.Thermatron 100 comprises: act as the magnetron 13 that part takes place high frequency waves, be used to produce high frequency waves; Steam generation part 15 is used for producing steam in heating chamber 11; Circulating fan 17, be used to stir and the heating chamber 11 that circulates in air; Act as the convection heater 19 of heating chamber air heater, be used to heat the air of circulation in the heating chamber 11; And infrared ray sensor 20, be used for by being arranged on the internal temperature of the exploration hole detection heating chamber 11 in the heating chamber 11.
Circulating fan 17 is provided with in the mode that its pivot is arranged on the center of rectangular clapboard 27.Rectangular ring convection heater 19 is arranged in the circulation fan chamber 25 in the mode around this circulating fan 17.In addition, be formed on the front that dividing plate 27 interior suction air vent holes 29 are arranged on circulating fan 17.Air-supply air vent hole 31 is provided with along rectangular ring convection heater 19.This device is set for when circulating fan 17 rotation, and wind to side flow thereafter, is provided with drive motors 23 at its rear side from the front side of circulating fan 17.Thereby the air in the heating chamber 11 is by sucking the core of air vent hole 29 suction circulating fans 17.Then, air passes the convection heater 19 that is arranged in the circulation fan chamber 25.At last, air is blown in the heating chamber 11 from air-supply air vent hole 31.Thereby in agitation, the air in the heating chamber 11 is followed this flow process by fan room 25 and is circulated.
Magnetron 13 is placed in the space that provides under the heating chamber 11 for example.Agitator blade 33 is arranged on the position that receives the high frequency waves that magnetron produces.In addition, the high frequency waves of magnetron 13 generations are radiated on the agitator blade 33 of rotation.Thereby high frequency waves supply in the heating chamber 11 when being stirred by agitator blade 33.Say that by the way magnetron 13 and agitator blade 33 not only can be arranged on the bottom of heating chamber 11, and can be arranged on its end face or the side.
Fig. 5 is the calcspar that the control system that is used to control the thermatron 100 that has steam generating function is shown.Mainly the control section 501 of microprocessor constitutes this control system by for example having.Control section 501 mainly is to carry out signal transmission work between power unit 503, storage area 505, input operation part 507, display screen 509, heating part 511 and cooling fan 61.
Heating part 511 is connected on high frequency waves generation part 13, steam generation part 15, circulating fan 17 and the infrared ray sensor 20.In addition, high frequency waves generation part 13 is by stirring part 33 (that is the drive part that, is used for the agitator blade) collaborative work with high frequency waves.Steam generation part 15 is connected on evaporation pan heater 37 and the heating chamber air heater 19 (that is convection heater).By the way, though this calcspar comprises composed component outside the above-mentioned mechanical composed component (for example, water delivery pump 55, door air-supply valve (blast damper) 84 and exhaust valve (exhaust damper) 87), the composed component outside these above-mentioned mechanical composed components is explained in the description of another embodiment below.
Then, below with reference to the flow chart of Fig. 6, the basic operation of the above-mentioned thermatron 100 that has steam generating function is described.
In operation sequence, at first, heated food product to be put in the plate, place then in the heating chamber 11.Subsequently, close On/Off door 21.Then, by utilize input operation part 507 to set heating means and heating-up temperature or time in step 10 (after this abbreviating S10 as).Thereupon, start switch (S11).Then, carry out heat treated (S12) by the work of control section 501.
That is, control section 501 reads the heating-up temperature or the time of setting, then according to the temperature or the selection of time that read and carry out best cooking methods, and judges whether (S13) device reaches the heating-up temperature or the time of setting.When reaching the set point of heating-up temperature or time, device stops each thermal source, and finishes heat treated (S14).Say that by the way at S12, steam generation, the work of heating chamber air heater, the rotation and the high-frequency heating work of circulating fan are carried out individually or simultaneously.
To describe below in the aforesaid operations process and to select and to carry out work under " steam produces and circulating fan is opened " pattern situation for example.When this pattern of selection, evaporation pan heater 37 is connected, and as shown in Figure 7, Fig. 7 illustrates the work of thermatron 100.Thereby the water that is stored in the evaporating dish 35 is heated, thereby produces steam S.The steam S that rises from evaporating dish 35 is from being arranged on the core that near dividing plate 27 cores suction air vent hole 29 is inhaled into circulating fan 17.Then, steam is sent in the heating chamber 11 by circulation fan chamber 25 from the air-supply air vent hole 31 that is arranged in dividing plate 27 peripheral parts.The steam of being sent into stirs in heating chamber 11.Subsequently, the steam of stirring sucks in the circulation fan chamber 25 near the suction air vent hole 29 that is arranged on dividing plate 27 cores once more, thereby, in heating chamber 11 and circulation fan chamber 25, formed circulating path.Say that by the way under the position that this device is configured to blow that air vent hole 31 is not arranged on the dividing plate 27, circulating fan 17 is set, and the steam that is produced is introduced and sucked in the air vent hole 29.In addition, shown in the hollow arrow among this figure (outline arrow), steam circulates in heating chamber 11, thereby steam is blown on the article.
At this moment, the steam in the heating chamber 11 can be heated by connecting heating chamber air heater 19.Thereby the temperature of the steam of circulation can be set at higher value in heating chamber 11.Therefore, obtained so-called overheated steam.So overheated steam can make culinary art carry out in the mode on burned article M surface.In addition, under the situation of carrying out high-frequency heating, magnetron 13 is connected.In addition, agitator blade 33 rotations.Thereby high frequency culinary art uniformly can be by infeeding high frequency waves in the heating chamber 11 and stirring high frequency waves simultaneously and carried out.
Thereby being formed steam according to the thermatron that has steam generating function of this embodiment is not to produce in the outside, but heating chamber 11 inboard generations.So, be similar to the situation of cleaning heated chamber 11, produce the part of steam, promptly evaporating dish 35 can easily clean.For example, in producing steam course, calcium, magnesium and chlorine composition contained in the moisture condense sometimes, deposit and are fixed on the bottom of evaporating dish 35.Yet evaporating dish can be only adheres to evaporating dish 35 lip-deep materials and gives wiped clean by cleaning.In addition, when evaporating dish 35 severe contaminations, evaporating dish 35 can be cleaned from heating chamber 11 interior taking-ups by (with it), as shown in Figure 8.Thereby the cleaning of evaporating dish 35 can easily be carried out.In addition, in some cases, evaporating dish 35 can be easily with new being changed.Therefore, help comprising the cleaning of the heating chamber 11 of evaporating dish 35.So the internal environment of heating chamber 11 remains under the sanitary condition always.
In addition, this thermatron is modified into evaporating dish 35 and is arranged on the rear side bottom surface, and this rear side bottom surface is that the article at heating chamber 11 export on the relative side.Thereby evaporating dish 35 can not become the obstacle that takes out article.In addition, even be under the high-temperature condition, article taken out or also can not exist when putting into heater user's hand to touch the danger of evaporating dish 35 from heater the user at evaporating dish 35.So this heater is as safe as a house.
In addition, as understanding that from the position between evaporating dish as shown in Fig. 9 and the bottom of heating chamber relation evaporating dish 35 is arranged at this position, that is, the end face 35b of evaporating dish 35 is in height h place on the bottom surface of heating chamber 11.Thereby, prevented to flow into the evaporating dish such as the bottom surface of the liquid that is exuded to juice on heating chamber 11 bottom surfaces etc. from article by heating chamber 11.So evaporating dish 35 can remain under the sanitary condition.In addition, the surface 22 of the step part between evaporating dish 35 and the bottom surface exports towards article.Thereby this surface 22 can be cleaned easily.
In addition, in this heated at high speed device, steam is by being produced by means of evaporation pan heater 37 heating evaporation wares 35.Thereby this heated at high speed device can provide steam efficiently by adopting simple structure.And the steam that is under the high temperature a little produces by heating.This feasible culinary art can simply be carried out by humidification, and cooks by the heating article and undertaken, and also prevents to carry out simultaneously the article drying of high-frequency heating.
In addition, the radiant heat of evaporation pan heater 37 is launched device 39 towards evaporating dish 35 reflections.Thereby the heat that evaporation pan heater 37 produces can be used to produce steam effectively, and not waste.
In addition, this thermatron forms air in the heating chamber 11 by the circulating fan circulation and stir.Thereby when carrying out Steam Heating, steam can be all equably around heating chamber 11 circulations.Therefore, heating chamber 11 is full of steam.Yet steam can not stagnated.Thereby steam can circulate in whole heating chamber 11.So when the article temperature was measured by infrared ray sensor 20, this infrared ray sensor 20 was measured the temperature of article reliably, and can not measure the temperature of steam particle in the heating chamber 11.Thereby, can improve the certainty of measurement of article temperature.So, can correct execution by the heat treated of carrying out with reference to the temperature that detected, and can not lead to errors.
In addition, high-frequency heating and Steam Heating the two can carry out simultaneously as heating means.Perhaps, can carry out separately one of in high-frequency heating and the Steam Heating.Perhaps, high-frequency heating and Steam Heating the two can carry out according to predefined procedure.These modes of carrying out heating means can freely be selected and implement.Thereby, can be according to the kind of food, be frozen food or chilled food and select suitable cooking methods arbitrarily.Especially, adopting under the two the situation of high-frequency heating and Steam Heating, can increase temperature increase rate.Thereby realized efficient culinary art.
In addition, this device air of forming in heating chamber 11 circulation can be heated by the heating chamber air heater 19 that is arranged in the circulation fan chamber 25.Thereby the steam that produces in heating chamber 11 can free adjustment.For example, the temperature of steam can be set at and be equal to or higher than 100 ℃.Thereby the temperature of article can fully be raise by superheated steam.In addition, the surface of article is dried.In some cases, the surface of article may be by burned.In addition, be under the situation of frozen food at article, because therefore the bigger thermal capacity of steam can carry out heat conduction effectively.Thereby article can quick-thawing.
In addition, in having this thermatron 100 of steam generating function, circulating fan 17 is contained in the circulation fan chamber 25, and the latter is arranged on heating chamber 11 outsides independently by dividing plate 27.This adheres to possibility on the circulating fan 17 with regard to eliminated the juice that splashes in the article cooking process.Simultaneously, ventilation is undertaken by the air vent hole 29 and 31 that is arranged on the dividing plate 27.Thereby the flow of steam that produces in heating chamber 11 can give freely changing according to air vent hole 29 and 31 set positions and the aperture area of air vent hole 29 and 31.
Say that by the way above-mentioned evaporating dish 35 is configured to the water groove can have one of following each shape.Figure 10 shows the schematic configuration figure in the cross section that shows another kind of shape evaporating dish, and also shows evaporation pan heater.Figure 11 shows along the profile of the line A-A intercepting of Figure 10.Figure 12 illustrates along another example of the profile of the line A-A intercepting of Figure 10, and Figure 13 shows the schematic diagram of the section of the evaporating dish that shows another kind of shape.
Evaporating dish 42 shown in Figure 10 has tapering part 42a, and this tapering part is separately positioned on the both ends of evaporating dish.Thereby the water groove vertically shoals in each tapering part gradually along it.The water that injects the water groove flows along tapering part 42a, and always leaves in the mid portion of evaporating dish.Owing to this structure, can reduce the overall length of evaporation pan heater 37.Thereby, can obtain compact evaporation pan heater.In addition, though the cross section of water groove floor can be the plane as shown in figure 11, its cross section can be the same shape of image surface as shown in figure 12.When its cross section had curve form, the water that leaves in the water groove always was collected near in the lowermost portion of evaporation pan heater 37.Thereby, improved the efficiency of heating surface of installing.The bottom surface that evaporation pan heater 43 shown in Figure 13 is configured to the water groove longitudinally forms in the mode with curve form.So water leaves near the mid portion that heat concentrates.Thus, can heat by improving the heat efficiency.
In addition, the place that evaporating dish 35 is placed in heating chamber 11 is not limited to article at heating chamber 11 and exports on the rear side bottom surface on the relative side, but can suitably change.As the placement example of the evaporating dish shown in Figure 14 A and the 14B, this position can be (under the sample situation shown in Figure 14 A, to be the bottom surface of one side of the sidewall surfaces 81a shown in the figure) along the bottom surface of a sidewall surfaces 81a and 81b.In addition, can place one or more little evaporating dishes 44 as shown in Figure 14B at the corner (or corner portions located) of heating chamber 11 bottom surfaces.In this case, each little evaporating dish 44 for example is bowl-shape evaporating dish, and it has the evaporation pan heater that is provided with on its underpart.Evaporating dish arbitrarily can be set, as long as this evaporating dish can supply to steam in the heating chamber in the given position.Say that by the way the steam that is produced upwards flows usually.Thereby, from the viewpoint of stirring steam preferably evaporating dish be arranged under the heating chamber.For example, preferably evaporating dish is arranged on the heating chamber Lower Half, perhaps along the bottom of heating chamber setting.In addition, under the situation that the cleaning of evaporating dish is carried out easily, evaporating dish can be arranged in the space lower under the bottom of heating chamber.In addition, might not be fixed to the precalculated position by evaporating dish, and the user can be placed on any position with evaporating dish.In this case, the steam generation source can be positioned at optimum position according to heating condition.
Second embodiment
Then, below with reference to Figure 15 A, 15B and 16 thermatrons of describing as second embodiment of the invention that have steam generating function.Say by the way, in the following description, indicate that these parts is described in this omission thus with identical Reference numeral used during same parts among first embodiment is described by first embodiment.In the thermatron that has steam generating function according to this second embodiment, shown in Figure 15 A, the end face of evaporating dish 35 is covered by lid 41, and lid 41 is provided with the aperture 41a that forms in its part.Thereby shown in Figure 15 B, steam can be limited on the specific part of aperture 41a from the position of its output.In addition, the quantity of steam of being supplied with can be regulated according to the aperture area of aperture 41a.
As shown in figure 16, this aperture 41a is arranged on and sucks under the air vent hole 29, is arranged in the core of dividing plate 27 and suck air vent hole 29.Therefore, when the steam that is produced when aperture 41a rises, steam directly is sucked into and sucks in the air vent hole 29.Thereby steam becomes circulating of circulating in heating chamber 11, and can not waste steam.In addition, when lid 41 is dismountable structure, then be convenient to cover 41 with another lid replacing of the aperture with different size.Thereby, can use suitable lid according to heating condition.
In addition, as shown in figure 16, have in the thermatron of steam generating function at this, a plurality of air-supply air vent hole 31a that are provided with in the dividing plate 27 are formed on its underpart, thereby being sucked into the most of steam that sucks in the air vent hole 29 can mainly blow out near the position heating chamber 11 bottom surfaces.This is because steam itself raises, thereby and when most of steam when the bottom blows out, compare with the situation that most of steam blows out from other parts whole mobile can this fact of homogenizing.Thereby the vapor stream in heating chamber 11 upwards flows after at first lower flows near its bottom surface.Say that by the way air-supply air vent hole 31b is arranged on the almost half height part place of dividing plate 27.This be because, place it on will heated article second layer carriage (not shown) be positioned at almost half height and position place of heating chamber 11, and air need be delivered on the article of placing on this carriage.
Because this structure has produced such circulating, that is, circulate by this, it is more efficient to add the heating of carrying out among above-mentioned first embodiment of ratio of specific heat.Thereby, in the Temperature Distribution in heating chamber 11, variations in temperature are limited to more among a small circle.Therefore, the article that are placed in the heating chamber 11 can be with heating equably at a high speed.
In addition, lid 41 can be changed with another lid, and the latter's perspective view is shown in Figure 17.This covers 45 shapes and resembles a plate, wherein vertically is provided with a plurality of circular hole 45a along it.Sentence on its thickness direction to form supporting leg part 45b respectively from its outstanding mode at this lid 45 back side four jiaos, they are used to form separately apart from the gap of the end face predetermined space of evaporating dish 35.This lid 45 is by cordierite (2MgO2Al
2O
35SiO
2) make, this material is the lower advanced low-k materials of ripple loss.This covers 45 heat shock resistances, and has greatly to lid 45 mechanical strengths that are difficult to break.
As shown in figure 18, the gap 46 with predetermined space t is provided with to evaporating dish 35 by each supporting leg part 45b of lid 45.When the water in the evaporating dish 35 heated, this gap 46 had suppressed to cover the rising of 45 bottom pressure.Thereby,, also pressure can be discharged from the gap effectively even the temperature of the water in the evaporating dish 35 raises and bumping takes place.This has prevented that water from splashing from the 45a of hole.Therefore, the steam that is produced can upwards stably flow from aperture 45a.Say that by the way even when bumping takes place, flow path is evaporated 47 bendings of flange portion that ware 35 both sides are provided with.Thereby water can not splash from gap 46.So shipwreck is in scattering and adhere on heating chamber 11 inboards.
