Heating device

Technical field

The present invention relates to the heating device of micro-wave oven etc.

Background technology

All the time, in the heating device of family expenses micro-wave oven etc., carry out cooking more equably and output when having adjusted heating for quicker.

For example when the cooking needs with the cooking of strong fiery cooking etc., in order in qualification electric power, to cook at short notice, by radiation within a certain period of time the microwave of high output carry out cooking.

In addition, when wanting to have the barbecue color on the surface of heating object, in order to make the air in the heating clamber is uniform temperature, and the heater by certain output is when adding hot-air, utilize fan to carry out the hot blast cooking, can carry out the uniform heating cooking thus with the indoor air of hot blast agitating heating.

On the other hand, in order in micro-wave oven, to utilize use sensor adjustment heating means just can be suitable for the heating of heating object and to study.

As an example, in the device that has carried the temperature sensor that in heating clamber, can measure the heating object temperature, adjust while the surface temperature of measuring heating object, to adjust so that finish the cooking up to the surface temperature arrival design temperature of heating object with design temperature by carrying out cooking.

In addition, also proposed following heating device: the temperature by corresponding heating object is switched heating process, is suitable for the cooking of food most.

For example, at patent documentation 1: proposed following scheme in the TOHKEMY 2005-296001 communique: utilize food taste in cooling or insulation to infiltrate easily and keep operation and the refrigerating work procedure and the insulation operation of boiling by switching, an amount of flavoring is infiltrated in the food, prevent well-done cooking method.

Other has also proposed following heating means: utilize the thermal source method afford heating object energy in addition of generation heat such as heater or microwave to keep delicious composition in the heating object.

For example, at patent documentation 2: proposed following scheme in the TOHKEMY 2002-147762 communique: by with the high-energy radiation of visible light of laser etc. on heating object, compare with situation about only heating with heater, can promote to be included in protein in the heating object to amino acid whose decomposition, promote amino acid whose increase as the delicious composition in the heating object.

The amount of the delicious composition in the heating object has much relations with the enzyme that is included in the heating object, and is active by enzyme is taken place, and can increase delicious composition, can reduce delicious composition on the contrary.

Just, there is the temperature range that is suitable for increasing the temperature range of the delicious composition in the heating object or causes delicious composition to decompose in the heating object respectively.

In addition, the bottom in heating clamber 3 disposes the workbench 31 of almost fixed, places heating object 7 and carry out cooking on this workbench 31.

In addition, folding and unfolding controlling organization 81 or magnetron 82 in Machine Room 8, heating arrangements is made of this magnetron 82, the hot air heater 62 that is arranged on the upper heater 61 of heating clamber 3 tops and is arranged on heating clamber 3 rears, by these heating arrangements the heating object 7 that is placed on the workbench 31 is carried out best cooking.

Under the situation of irradiation as the high frequency waves heating (being called heating using microwave) of the microwave of high frequency waves, microwave from magnetron 82 radiation, stir radiation on one side by the rotary antenna 83 that is rotated motor 84 rotations in heating clamber 3 on one side, heating is placed on the heating object 7 on the workbench 31 equably.

In addition, under the situation (being called the barbecue heating) of the radiant heat heating of having used upper heater 61, by the radiant heat heating heating object 7 of upper heater 61.

In addition, under the situation (being called oven heat) of the convection type heating of having used hot air heater 62, utilize the fan 23 that rotates by motor 22 that the air (hot blast) that is heated by hot air heater 62 is circulated in heating clamber 3 and heat heating object 7.

Three heating arrangements of this heating using microwave, barbecue heating, oven heat are freely controlled, are driven by controlling organization 81.

For example, can make up a plurality of heating arrangements and drive simultaneously, also can a plurality of heating arrangements of driven or driving successively.

But the front of heating clamber 3 is the structures by door 5 switches, even if door 5 is provided with the viewer 51 that also can confirm inner heating object 7 states under this 5 pent state.

In the side of heater 3 light irradiating means 4 is set, to heating object 7 irradiates lights that are placed on the workbench 31.

Here, light irradiating means 4 is surrounded by reflecting plate 41, enters in the heating clamber 3 from plate 41 reflections that are reflected of the light of light irradiating means 4 irradiations, is radiated on the heating object 7 again.

In addition, by in light irradiating means 4, using the lamp of irradiation visible light, can make in the heating clamber 3 to brighten, so that the user can be clear that the situation of heating object 7.

Below, the process of using micro-wave oven 1 to cook is described.

At first, user's door 5 of opening micro-wave oven 1 is placed on heating object 7 on the workbench 31 in the heating clamber 3.

Thereafter, close door 5, utilize the operation control panel 52 that is configured on the door 5 to select the kind of the food or the cooking, press start button (not shown), indication begins the cooking.

When indication began to cook, the controlling organization 81 of micro-wave oven 1 was according to the food or the cooking with operation control panel 52 appointments, and the heating arrangements of control magnetron 82, upper heater 61, hot air heater 62 carries out the heating of corresponding heating object 7.

Here, as an example, the heating mode when utilizing Fig. 3 that cooking chicken is described.

This Fig. 3 represents that the time that an example uses micro-wave oven 1 cooking of the present invention to export P as the internal temperature T and the magnetron of the heating object 7 in the chicken process of heating object 7 changes.This cooking pattern can fully induce the delicious composition that chicken had as heating object, makes the cooking better to eat than existing cooking become possibility.

At first, the internal temperature of the relevant heating object of explanation and the relation of delicious composition before this cooking of explanation, in the occasion that heats the meat that contains chicken rapidly, maintenance is as a kind of inosinicacid of delicious composition, under the situation of slowly heating, decompose inosinicacid, increase amino acid as other delicious composition.

In addition, the activity of the enzyme of the delicious composition of decomposition inosinicacid etc. lost efficacy in the time of 50 ℃～55 ℃, lost effect when surpassing 80 ℃ of time variations.These facts all have introduction in document or cooking program.In addition, in the temperature range of enzyme activation, high more its effect of temperature is high more also to be well-known.

As above as can be known, the inosinicacid as delicious composition when the pass of delicious composition and temperature ties up to low temperature does not decompose, but along with the rising of temperature, delicious composition is decomposed.Specifically, in the decomposition that takes place below 55 ℃ as the inosinicacid of delicious composition, do not decomposing more than 55 ℃.In addition, generating delicious composition below 80 ℃, do not increasing and decreasing delicious composition more than 80 ℃.

As above as can be known, in Fig. 3, the internal temperature T of heating object 7 uses heating arrangements to control by controlling organization 81, so that slowly rise from time (01) interval that begins to be heated to 40 ℃ (T0), rise rapidly from time t (-) interval of 40 ℃ of (T0)～55 ℃ (T1), in the time t (+) in ℃ (T2) interval, 55 ℃ of (T1)～80, roughly pass definitely, rise rapidly once more in time t (02) interval that surpasses 80 ℃ (T2).

Here, time t (+) is included in the time of the delicious composition increase (+) in the heating object 7, time t (-) is included in the time of the delicious composition minimizing (-) in the heating object 7, and time t (01) and time t (02) are included in the indeclinable time of amount of the delicious composition in the heating object.

The output P of magnetron is 350W in time t (01) interval, is the output of 1000W in time t (-) interval, is 0W in thereafter time t (+) or time t (02).

Just, interval from the time t (01) that begins to heat by hanging down the microwave irradiation of output on heating object 7 with magnetron, the temperature of heating object 7 is slowly risen, thereafter, be set at high output in time t (-) interval by output, thereby be increased sharply the programming rate of heating object 7 magnetron.At this moment, programming rate is meant the ratio that the internal temperature T of heating object 7 changes to higher direction.

In addition, cut off the output of magnetron, as far as possible the internal temperature T of heating object 7 is remained necessarily by the cooking of having used other heating arrangements in the interval of time t (+).

Here, contain the enzyme of decomposition as the inosinicacid of delicious composition in the chicken, this enzyme not too can be activated at room temperature, but in the high more easy more activation of temperature in the temperature range of non-inactivation, in activation fully more than 40 ℃.

In addition, this enzyme is inactivation in the time of 55 ℃, can not decompose inosinicacid.

Just, owing to be decomposed by the effect of inosinicacid catabolic enzyme in 40～55 ℃ temperature range as the inosinicacid that is included in the delicious composition in the chicken, in this temperature range, inosinicacid reduces.

In addition, when decomposing, the protein that constitutes chicken generates the amino acid that contains delicious composition.

In addition, contain the enzyme of decomposing protein in the chicken, this enzyme is activating below 80 ℃, at inactivation more than 80 ℃.

Just,, generate the amino acid that contains delicious composition in the temperature range below 80 ℃, so in this temperature range, amino acid increases because the effect of protein by protein decomposition enzyme that is included in the chicken is decomposed.

But as mentioned above, owing to can decompose at inosinicacid below 55 ℃, in 55 ℃～80 ℃ the temperature range that inosinicacid can not decompose and amino acid increases, the delicious composition in the chicken increases.

As above as can be known, by reducing 40～55 ℃ temperature range of delicious composition, can improve the survival rate of delicious composition by as far as possible at short notice.

In addition, stop long cooking, can increase delicious composition by 55 ℃～80 ℃ temperature range and preferred 60 ℃～75 ℃ temperature range that increases at delicious composition.

In addition, below 40 ℃ or in the temperature range more than 80 ℃, not observing delicious composition has significant change.

Here, Fig. 4 and Fig. 5 represent that respectively the time of the internal temperature T of the heating object in the cooking process of existing micro-wave oven changes.

The time of the internal temperature T of the heating object that Fig. 4 is expressed as the height output of shortening the cooking time and making magnetron when necessarily carrying out cooking changes.

Because the output of magnetron is constant height output when end of cooking when beginning to cook, so the internal temperature of heating object also is to rise with roughly certain speed always.

In this gastronomical process, in 40 ℃～55 ℃ temperature range, carry out the time t (-) of cooking and carry out among the time t (+) of cooking 55 ℃～80 ℃ temperature range, the programming rate of heating object 7 is almost constant, though delicious composition increases because the reduction of delicious composition is also many, so can not fully increase delicious composition.

In addition, Fig. 5 is illustrated in the time variation of the heating object internal temperature T when only utilizing oven cook to carry out cooking.

The internal temperature T of heating object slowly rises when beginning to cook, and along with the rising of temperature, it is big that rate of rise in temperature also becomes.

In this gastronomical process, in 40 ℃～55 ℃ temperature range, carry out cooking time t (-) time and in 55 ℃～80 ℃ temperature range, carry out among the time t (+) of cooking, programming rate among the time t (+) is fast, because the recruitment of the delicious composition in the heating object 7 tails off, it is many to reduce quantitative change, so cause that delicious composition reduces in gastronomical process.

Relative therewith, in the heating mode of micro-wave oven of the present invention 1 shown in Figure 3, its heating mode is as follows: in the zone of the time t (01) of the internal temperature T of heating object 7 above 40 ℃, slowly heating is so that can evenly heat chicken, Fast Heating in the zone of the time t (-) that 40 ℃～55 ℃ delicious compositions reduce, thereafter slowly heating in the time t (+) that 55 ℃～80 ℃ delicious composition increases, at last, in the temperature more than 80 ℃, as finishing the cooking with improve temperature shown in the t (02) like that quickly.

Just, by control the internal temperature of heating object 7 by controlling organization 81 control heating arrangements, make that the time aspect programming rate of the time t (-) that delicious composition reduces is faster than the programming rate of the time t (+) of delicious composition increase.

Like this, when cooking chicken, by cooking with heating mode shown in Figure 3, compare the existing heating mode of Fig. 4 or Fig. 5, because the reduction that can reduce delicious composition increases the recruitment of delicious composition, so can increase the delicious composition in the heating object, compare existing apparatus and can induce delicious cooking and become possibility, can carry out more good to eat cooking.

In addition, cook, owing to can make the surface have the delicious and crisp sense,, can make and make the people feel better to eat cooking so can increase appetite when having meal by final raising temperature.

Here, heating object 7 is not chicken but the situation of other food, because the identical temperature range that has activating enzymes with chicken, so the absolute temperature of T0, T1, T2 is different because of the enzyme in the food, but by using identical heating mode, the cooking that utilizes enzyme to increase the delicious composition of food becomes possibility.

For example, in beef or other meat of this class of pork, also contain composition or enzyme with the roughly the same kind of chicken owing to be included in the catabolic enzyme of delicious composition in the food or delicious composition and protein decomposition enzyme, so by in the temperature T 0=40 identical ℃, T1=55 ℃, T2=80 ℃ with the example of chicken, use identical heating mode to control, can increase the delicious composition of food.

In addition, in greengrocery, utilize the enzyme that sugar is decomposed into glucose,, can increase the cooking of delicious composition or sugariness by carrying out the temperature control identical with meat.

In addition, same, by utilizing the enzyme that improves the combination between the cell that is included in the greengrocery, owing to also can prevent the cooking that greengrocery is well-done and so on, so the good cooking of appetite becomes possibility.

In addition, owing to not giving the cooking that moisture disperses moisture, so the rate that retains of vitamin is also high, the cooking that has concentrated delicious composition becomes possibility.

Have, the delicious composition in the embodiments of the present invention is meant that with above-mentioned inosinicacid be main the comprise amino acid of glutamic acid, aspartic acid, guanylic acid (acid of グ ア ニ Le) etc. or the material of being called delicious composition usually of its compound again.

Here, as the method that heats according to this heating mode, can be utilize heating using microwave as the magnetron 82 of heating arrangements, utilize the barbecue heating of upper heater 61 or utilize hot air heater 62 oven heat, and the not shown heat of utilizing steam heat steam-heated any one.

But, in the cooking the when temperature of time t (01) zone in Fig. 3 etc., heating clamber 3 is low, utilize microwave cooked the best of magnetron 82.

In addition, same, time t (-) zone heating rapidly utilizes magnetron 82 to heat heating using microwave the best of heating object 7 internally.

Here, in time t (01) zone and time t (-) zone, because delicious composition reduces in time t (-) zone,,, the temperature in time t (-) can become the cooking of the survival rate that has improved delicious composition if rising soon so the temperature of comparing among the time t (01) rises.

Therefore, bigger by the output that makes the magnetron 82 among the time t (-) than the output of the magnetron 82 among the time t (01), can improve the survival rate of delicious composition.

In Fig. 3, at heating object 7 is under the situation of chicken, the output P1 that for example understands the magnetron 82 in time t (01) is 350W, the output P2 of the magnetron 82 in time t (-) is the example of 1000W, but, then do not limit the output P1 of magnetron 82, the absolute value of P2 especially as long as output P2 is bigger than P1.

Here, by make output P2 in this gastronomical process is the highest output of magnetron 82, owing to the reduction of delicious composition can be controlled at bottom line, so in the cooking of having used magnetron 82, can further improve the cooking of the survival rate of delicious composition.

For example, because usually the electric power of family expenses is 1500W, so in the time will increasing to 1000W,, can further improve the survival rate of delicious composition by P2 being set at the 1000W of the highest output to the efficient of magnetron 82 as the highest output of magnetron.

Here, represented the situation of low output P1=350W, high output P2=1000W in the output of magnetron 82, but, then do not limited the absolute value of output so long as low output and high output are the structures that stage or the stage of nothing ground switch.

In addition, according to the kind of heating object 7, can also change the low output valve of magnetron 82, high output valve.

In addition here, in time t (+) zone etc., temperature situation about less keeping with rising, utilize oven heat or Steam Heating the best of hot air heater 62, the situation of finishing the surface rightly in time t (02) zone etc., utilize the barbecue heating of upper heater 61 best, the kind of the heating arrangements in does not limit especially At All Other Times.

In addition, represented that here heating means are situations of heating using microwave and oven heat and barbecue heating, but the kind of heating arrangements or quantity do not limit.For example, as mentioned above, also can possess Steam Heating as heating arrangements.

Promptly, by heating clamber 3 in, producing steam, can utilize the evaporation latent heat of steam to give surface calorimetric greatly, used the heating of steam by utilization, can use lower energy ascending temperature or holding temperature.

In addition, the quantity of the quantity of the employed hot air heater 62 of oven heat or the employed upper heater 61 of barbecue heating is several all right.

In addition, represented the structure of configuration Machine Room 8 below heating clamber 3 here, but the position of Machine Room 8 can be at any place.

In addition, represent the structure that rotary door 5 up and down comes switch here, but do not limited the switch direction of door 5.

In addition, represented the relevant micro-wave oven that possesses the workbench 31 that roughly is fixed here, but workbench 31 also can be a rotary work-table.

As mentioned above, in the micro-wave oven 1 of present embodiment,, compare, can increase the cooking of the delicious composition in the heating object with existing cooking method by being suitable for the cooking of heating object.

Embodiment 2

Fig. 6 represents that the time of the internal temperature of the heating object in the cooking process of micro-wave oven of second embodiment of the invention changes and heating mode.

Micro-wave oven 1 its cooking pattern of the present invention is as follows: the oven heat of the heating using microwave of the low output of combination and low output heats when beginning to heat, carry out the heating using microwave of high output then, the oven heat of the low output of combination thereafter and the Steam Heating of low output heat, and roast heating at last.

Here each heating mode is elaborated.

At first, made up the cooking of the heating using microwave of initial low output (350W) and the oven heat of hanging down output (650W) till the internal temperature of heating object arrives T0.

Because the temperature of heating clamber is low when beginning to heat, it is low to add the ability of pining for heating heating object at oven heat or barbecue, so directly heat heating object and improve temperature by carrying out heating using microwave, again by and after the temperature of raising heating clamber, be used for oven heat or the steam-heated heat of giving with oven heat.

Here, when after beginning to heat, carrying out the heating using microwave of high output immediately, owing to produce uneven situation when having the heating of heating object situation etc. of heating uniformity difference, so the low output about the preferred as mentioned above 350W of the heating using microwave of carrying out immediately after beginning to heat.

In addition, by during the heating using microwave of hanging down output, also using oven heat,, can prevent the heating object cooling after the heating using microwave because the temperature of heating clamber is risen.

Secondly, utilize the cooking of the heating using microwave of high output (1000W) from T0 to T1 interval at the internal temperature of heating object.

In the internal temperature of heating object time t (-) interval from the temperature range of T0～T1, in order to prevent the minimizing of the delicious composition in the heating object, but by heating using microwave being set at high output Fast Heating heating object.

Here, because time t (-) zone is than time t (01) zone, the effect height that delicious composition in the heating object is reduced, so by being set at the output of the heating using microwave in time t (-) zone bigger than the output of the heating using microwave in time t (01) zone, can prevent the heating inequality of heating object by the heating using microwave of low output, simultaneously, can prevent the minimizing of delicious composition by the heating using microwave of height output.

Secondly, the internal temperature at heating object has made up the oven heat of low output and the steam-heated cooking of low output in T1～T2 interval.

Interval in order to increase the delicious composition in the heating object at the time of the temperature range of T1～T2 t (+) at the internal temperature T of heating object, the oven heat (750W) by utilizing hot air heater 62 remains on the increase that roughly certain temperature promotes delicious composition for a long time with the internal temperature T of heating object.
