In addition, make high frequency generating unit 13 produce high frequency, and make this high frequency diffusion and be transmitted into heating clamber 11 by the rotation of mixing arm 23.Whereby, high frequency absorbing film 81 heatings of pallet 21 and heating high frequency heater 77, this hot Q2 propagates to heating object by metallic plate 75.The superjacent air space that the gap that a part of Q3 of the high frequency that produces passes 21 on the internal face of heating clamber 11 and pallet enters pallet 21 carries out high-frequency heating to heating object.Wherein,, do not need sometimes heating object M is carried out too strong high-frequency heating, so should set the heat of Q3 smaller according to different heating targets.That is to say, though with the heating of high frequency heater 77 temperature of heating object M is risen, because be used for the high frequency of high frequency heater 77 heating usefulness is shielded by the metallic plate 75 of pallet 21, so can not supply on the heating object M.In addition,, power supply interface is provided in the situation of the heating clamber side of pallet 21 downsides, can shields high frequency too except from the bottom of heating chamber supply high frequency.
In addition, enter the superjacent air space 87 of heating clamber by steam conduit 29 from steam outlet 85 from the steam of steam generating unit 15, this heat of steam Q4 contacts with heating object M, by heat exchange heating heating object M.
By above radiant heat Q1, from a part of Q3, the heat of steam Q4 of the hot Q2 of high frequency heater 77, high frequency heat treated heating object M expeditiously.In addition, by each thermal source Q1～Q4 suitably being selected combination heating in order, can carry out only heat treated according to the heating purposes of heating object.In addition, can utilize the radioshielding effect of the metallic plate 75 of above-mentioned pallet 21, when heating object being steamed the cooking, suppress the superheated of high frequency, thereby carry out the real steaming method cooking.
In addition, by making the convection heater heating of not shown indoor gas heating part, can also be further high temperature heating heating object M equably.
Like this, because being used for the volume of the heating clamber of cooking is cut apart by pallet 21 and diminishes, so can make steam be full of heating clamber apace, and also rise to temperature (for example 100 ℃) sharp near steam in the supply by steam of the temperature inside the box of the superjacent air space of heating clamber 11.Therefore very fast just formation the after beginning to heat from high-frequency cooker 100 can carry out the state that the steaming method is cooked in heating clamber 11, shortened the time of cooking thus significantly.In addition, owing to when steam takes place, the temperature of heating clamber 11 is risen with upper portion heater 17, so can prevent heating clamber 11 dewfall.By changing the height of heating clamber 11 inner pallets 21, actual steam temperature can be adjusted in addition, like this, the power that temperature control just can change steam heated power simply need not be carried out.
In addition, the temperature that the Temperature Detector 31 that control part 39 heats indoor temperature according to the thermistor 65 and the detection of heater block 45 detects, FEEDBACK CONTROL steam generating capacity and heater add heat, correctly set temperature and vapor volume in the heating clamber 11, can easily carry out temperature whereby and control the inconvenient eggs cooking.
In addition, because will supply with the superjacent air space of heating clamber 11 from the steam of steam generating unit 15 by the steam conduit 29 that is configured in heating clamber 11 outsides, so gratin can be not dirty attached on the tube parts of steam conduit 29 grades it being done, thereby constitute the structure of cleaning easily.
In addition, because the high-frequency cooker of present embodiment 100, on the bottom surface corner of heating clamber 11, be equipped with two steam generators 15, so can make the vapor volume of generation variable according to the heating content of heating object, with its be divided into need the many situations of vapor volume and with on a small quantity with regard to passable situation, thereby can set the characteristic curve that steam is supplied with arbitrarily, so that reach required steam quantity delivered.
At this, be example with the heat treated of above-mentioned high-frequency cooker 100, describe the remarkable result of the present invention that embodies by each heat treated in turn in detail.
Figure 11 illustrates the heat characteristic curve example of the steaming method cooking.By this heat characteristic curve, at the heating initial stage, pallet is put into heating clamber 11, power at the fixed time to upper portion heater 17 and carry out preheating.After preheating finishes, stop to upper portion heater 17 power supplies, transferring to evaporation pan heater is sheathed heater 53 power supplies.Supply with steam to heating clamber whereby.
Being changed to of the temperature inside the box with this heat characteristic curve, open after preheating when being positioned in heating object on the pallet after the shutter door, the temperature inside the box once descended, when closing shutter door, the temperature inside the box rises rapidly, reaches near the i.e. normal condition 100 ℃ of steam supplying temperature very soon.Because the dewfall of the steam that produces nearly all produces on the surface of heating object,, the wall surface of heating clamber 11 etc. absorb few heat so going up.In addition, the dew that remains in the pallet 21 can be removed simply by taking off pallet.
In addition, do not carrying out preheating when evaporation pan heater is powered, the temperature inside the box rises slack-off, becomes long principal element of cooking time.And because the temperature inside the box reduces, the steam of generation is dewfall on each face of heating clamber 11 often, and the water of dewfall can remain in bottom of heating chamber.Need the operations of a lot of troubles for the dew of removing bottom of heating chamber and side in this case.
In addition, in heating during for example with the heating object of leaf vegetables, if do not carry out preheating, the green of band leaf vegetables will be not bright-coloured, and when carrying out preheating, bulk temperature in the heating clamber becomes more than 100 ℃, because carry out high efficiency steam heated of short time under the high steam ambient of concentration, can make the leaf vegetables lovely luster of processing.
Figure 12 illustrates at the time dependent curve of the temperature that heating object under the situation of without preheating is arranged.When carrying out above-mentioned preheating, the rate of rise in temperature of heating object is very fast, can reach target temperature rapidly and become stable state.In addition when not carrying out preheating, it is slow to slow down on the temperature of heating object, and the time that arrives target temperature is compared and will grow when carrying out preheating.
In addition, when planning further to promote in the heating clamber bulk temperature, as shown in figure 13, can be to upper portion heater and evaporation pan heater interleaved power, the electrical power sum that preferably top is added the electrical power of hot heater needs and evaporation pan heater needs is set at the maximum of the scope of allowing the electrical power value that is no more than high-frequency cooker 100, adds thermal effect thereby improve to greatest extent.Such heat characteristic is best suited for for example heating of root vegetables.In addition at this moment, even do not carry out preheating, the rising of heating indoor temperature is also than comparatively fast, but should carry out preheating in order to shorten the cooking time.
The following describes barbecue cooking example.
Figure 14 illustrates the heat characteristic curve example of the barbecue cooking.In the barbecue cooking, heating object M is positioned on the pallet 21, utilize the heating of upper portion heater 17 that heating object M is heated, made it burned vestige.At this moment, shown in Figure 14 (a), the temperature that begins main heating back heating object M after the preheating is: heat up rapidly after its upper face is heated, then heat the back programming rate in the inside of heating object M slower, and surface and internal temperature difference have the tendency of expansion at the heating initial stage.That is to say, be rapidly heated after being heated near the upper face of the heating object M of upper portion heater 17, but that because by the thermal capacity of hot thing M making heat from the surface pass to inside needs the time, so the internal temperature climbing step-down of heating object M.
Shown in Figure 14 (b), along with in the process of main heating, in heating clamber, supplying with steam, steam is dewfall on the surface of the heating object M lower than the steam temperature of supplying with, thereby absorbs surface temperature that heat of gasification makes heating object M temporarily descend (Δ T1) because of the water evaporation of this dewfall.In addition in the inside of heating object M, big approximately twice of the air of ratio of heat capacities heating clamber and the high-temperature steam higher than heating object M temperature contact with heating object M, the heat of steam is transmitted on the inner, high efficiency ground of heating object M, thereby make the intensification of heating object M quicken (Δ T2).Therefore can suppress surface and the temperature inside difference of heating object M very little.And by the steam lower than heating clamber temperature is provided in heating clamber, the temperature of the superficial layer that contacts with the air of heating object M is descended, can suppress the roasting overfocus in surface, and alleviate the deficiency of inner heating.
Mode of heating in the above-mentioned barbecue cooking also can use high-frequency heating to heat simultaneously.Figure 15 illustrates by using high-frequency heating to roast the heat characteristic curve example of heating simultaneously.
In the barbecue cooking of this moment, equipment high frequency heater 77 utilizes high-frequency heating pallet 21 to make its preheating as pallet (with reference to Fig. 9).Master after preheating adds and pines for, and heats cooking-vessel by only powering to the high frequency generating unit, the bottom surface side of heating heating object M.Then stop to the power supply of high frequency generating unit, beginning is to upper portion heater 17 power supplies, above the heating heating object M.Then in the process of utilizing upper portion heater 17 to heat at the fixed time to the power supply of the evaporation pan heater of steam generating unit, supply with steam to heating clamber.And when evaporation pan heater is powered, should stop to upper portion heater 17 power supply, the sum total of electrical power is no more than high-frequency cooker 100 allows the electrical power value so that accomplish to make.And both can repeat repeatedly the supply of steam, also can be after main heating beginning carry out the supply of steam after through the scheduled time continuously.
At this, pine for supplying with steam adding, if, then have the effect of giving heating object M moisture and making its moistening softness in preceding half section supply of cooking; If supply with, will have the good and barbecue color effect of uniform of the heating that makes heating object M inside in the cooking second half section.Even on the surface of heating object M, exist concavo-convex because steam can enter into this concavo-convex on, so can prevent from heating object M local barbecue duration and degree of heating deviation takes place, make the barbecue state even.Under situation, to being subjected to the concavo-convex position heating quantitative change that influences little, if this inhomogeneous but use steam heated just can not produce simultaneously with upper portion heater 17 heating.In addition, can prevent inhomogeneous heating in advance by 17 pairs of heating clambers of upper portion heater, it is burned because of superheated promptly to add the heating object that is positioned at heating clamber central authorities that adds the little heating inequality of heat on the many angles at heating clamber of heat and cause in heating clamber central authorities, and the heating object that is positioned on the heating clamber angle is insufficient and half-cooked because of heating.
Such heat characteristic pattern for example can be used for the cooking of kindred, makes the heating around the bone good, can suppress that the surface is burned fully heats inside, makes heating object have bulk and soft sense of food thus.
More than Shuo Ming each heating mode also can be used as cooking program and is stored in advance in the storage part 95 that is connected with control part shown in Fig. 3 39, forms by the operations such as automatic-cooking switch 97 of guidance panel 91 are carried out to select arbitrarily.At this moment, also can detect heating object temperature in the heating clambers with heating-up temperature detector 31, the temperature of contrast heating object, and measure process time such as heat time heating time with timer 99 and set the control timing of each part mentioned above.The vaporific time also can be adopted steam supply switch 101 is set on guidance panel 91 except that automatically being set according to predefined cooking program, begins to supply with steam from the random time of pressing this steam supply switch 101.Therefore, light inlet window 41a by shutter door 41 confirm heating object M cooking process and press steam in the required time and supply with switch 101, can supply with steam in the suitable time, thereby guarantee can not make the cooking failure, and improve the convenience of using.
More than should suitably set according to various conditions with to add kind, shape, weight and the cooking method etc. of heat because of heating object M different Shuo Ming the heat time heating time of utilizing upper portion heater, evaporation pan heater and high frequency generating unit.
Other configuration example of above-mentioned high-frequency cooker 100 will be described below.
Other formation example of corresponding steam generating unit mode of heating has been shown among Figure 16.Wherein Figure 16 (a) shows and makes heater block and evaporating dish form individual example respectively, and Figure 16 (b) shows the example with radiant heat heating evaporation ware.In the structure of Figure 16 (a),, come the heating evaporation ware by heater block being heated with sheathed heater 109 heaters such as grade with the following side contacts configuration of heater block 107 with evaporating dish 105.According to this formation, because evaporating dish 105 is connected with bottom of heating chamber, so the cleaning of ware face is easy to.
