Summary of the invention
Therefore, in order to solve described problem, main purpose of the present invention is to provide a kind of induction heating type processing unit (plant), and the structure of device is simplified, and device can not maximize, and the efficiency of heating surface is excellent, can to the both sides of machined object, apply heat simultaneously.
That is, the invention provides a kind of induction heating type processing unit (plant), it comprises: nonmagnetic metal part and magnetic metal part, arrange to clip the mode of machined object; And induction coil, with respect to described nonmagnetic metal part, be arranged on a side contrary with described magnetic metal part, the magnetic flux being produced by described induction coil connects described nonmagnetic metal part and by the inside of described magnetic metal part, described nonmagnetic metal part and described magnetic metal part are heated thus.
In addition, the invention provides a kind of induction heating type processing method, to clip the mode of machined object, nonmagnetic metal part and magnetic metal part are set, with respect to described nonmagnetic metal part, induction coil is arranged on to a side contrary with described magnetic metal part, by the magnetic flux that makes to be produced by induction coil, connect described nonmagnetic metal part and pass through the inside of described magnetic metal part, heat described nonmagnetic metal part and described magnetic metal part, thus described machined object is processed.
According to described scheme, owing to machined object being clipped between nonmagnetic metal part and magnetic metal part, with respect to nonmagnetic metal part, in a side contrary with magnetic metal part, induction coil is set, make the magnetic flux being produced by induction coil connect nonmagnetic metal part, so can heat nonmagnetic metal part.In addition, because the magnetic flux being produced by induction coil is after connecting nonmagnetic metal part, by the inside of magnetic metal part, so can heating magnetically metalwork.Can utilize thus nonmagnetic metal part and magnetic metal part heating machined object.In addition, owing to only in nonmagnetic metal part side, induction coil being set, so the structure of energy simplification device can not make device maximize, switching and the mounting or dismounting of the magnetic metal part being adjacent to nonmagnetic metal part become simply, make to take out or put into machined object to become easy.In addition,, owing to utilizing induction heating to heat nonmagnetic metal part and magnetic metal part, so the efficiency of heating surface is high, can not damage operability yet.
Specifically, can consider that described nonmagnetic metal part and described magnetic metal part are respectively bed die and mold.In this case, induction coil is located at the below of bed die.In order rightly bed die to be heated, preferably, make the face relative with induction coil of bed die be roughly planar shaped, make the magnetic flux being produced by induction coil substantially vertically connect bed die.
At this, owing to flowing through the electric current of induction coil and the faradic opposite direction producing in nonmagnetic metal part and magnetic metal part, so effect has the power (repulsive force) of mutual repulsion, produce sometimes the problem of magnetic metal part accidental.In order to address this problem, preferably, magnetic circuit is arranged on the central portion of described induction coil with iron core.By magnetic circuit is arranged on to the central portion of induction coil with iron core, owing to flowing through the magnetic flux of equidirectional on the thickness direction with iron core and magnetic metal part at this magnetic circuit, so produce the power (attraction) attracting each other.Therefore, induction coil, and nonmagnetic metal part and magnetic metal part between as can not acting on large repulsive force with joint efforts, so can prevent magnetic metal part accidental.
Preferably, be provided with magnetic flux path and form member, described magnetic flux path forms outside circumference and described induction coil and the face contrary side of described nonmagnetic metal part that member covers described induction coil, forms the magnetic flux path that the magnetic flux that produced by described induction coil passes through.According to this scheme, be formed with following magnetic circuit: the magnetic flux being produced by induction coil connects nonmagnetic metal part, arrive magnetic metal part, by behind the inside of this magnetic metal part, flow into magnetic flux path and form member.Its result, can be effectively the magnetic flux guiding nonmagnetic metal part and the magnetic metal part that are produced by induction coil.
Preferably, described nonmagnetic metal part forms member supporting by described magnetic flux path.According to this scheme, can form the structure that member forms supporting nonmagnetic metal part by magnetic flux path, can simplification device structure.
In addition, preferably, described magnetic flux path forms member and contacts with described magnetic metal part.According to this scheme, magnetic flux easily flows to magnetic flux path from magnetic metal part and forms member, can reduce magnetic resistance.
Preferably, with respect to described magnetic metal part, in described nonmagnetic metal part one side, nonmagnetic metal is shown consideration for and is tightly arranged on described magnetic metal part.Like this, if nonmagnetic metal is shown consideration for to the inner side that is tightly arranged on magnetic metal part, induced current flows and produces heat in nonmagnetic metal body, can make to be risen by the temperature that is adjacent to the nonmagnetic metal body of setting and the structural member (mold) that magnetic metal part forms.In addition, resistivity, the thickness of the nonmagnetic metal body being adjacent to by selection, can adjust the temperature rising value of mold.In addition so-called nonmagnetic metal style non-magnetic stainless steel, copper etc. in this way.
Preferably, with respect to described nonmagnetic metal part, in a side contrary with described magnetic metal part, resistivity is adjacent to and is configured on described nonmagnetic metal part than the low nonmagnetic material of described nonmagnetic metal part, or the resistivity nonmagnetic material lower than described nonmagnetic metal part is configured on described nonmagnetic metal part by heat conduction component.According to this scheme, the in the situation that of having produced local temperature inequality in nonmagnetic metal part, if the nonmagnetic material that resistivity is lower than nonmagnetic metal part is configured in the position that temperature is lower, induced current becomes and easily flows at configuration position, caloric value increases, temperature raises, so can eliminate temperature inequality.In addition, the nonmagnetic material of described low-resistivity can be adjacent to and be configured on nonmagnetic metal part, also can be configured on nonmagnetic metal part by heat conduction component.
Because the arranged outside in nonmagnetic metal part side has induction coil, so the heat dissipation capacity from nonmagnetic metal part is few, but the outside of magnetic metal part side is unlimited, many from the heat dissipation capacity of magnetic metal part, along with magnetic metal part becomes high temperature, specific temperature rise reduces.In order to address this problem, preferably, thermal insulation member is arranged on a side contrary with described nonmagnetic metal part with respect to described magnetic metal part.
At this, in the situation that make to be applied to the frequency of the alternating voltage on induction coil, be the low frequency that is less than 50Hz, nonmagnetic metal part is difficult to be heated, and in addition, the magnetic flux density of magnetic metal part becomes too high and saturated.On the other hand, in the situation that make described frequency for surpassing the high frequency of 1000Hz, nonmagnetic metal part, by superheated, is compared temperature with magnetic metal part and is become too high.Therefore, preferably, the frequency that is applied to the alternating voltage on described induction coil is 50Hz～1000Hz, by described frequency, controls the heating ratio of described nonmagnetic metal part and described magnetic metal part.。
In addition, the electric current permeability of nonmagnetic metal part is high, and interior outside is all heated.On the other hand, owing to being magnetic metal part, in frequency, be that 500Hz, temperature are at 300 ℃, electric current permeability is 2mm left and right, the face of the inner side contacting with machined object is heated, so can process machined object efficiently.
In addition, preferably, the power supply that described induction coil is applied to alternating voltage is the 3N frequency multiplication generator of transformer mode, and wherein, N is more than 1 odd number.At this, 3N frequency multiplication generator is in the situation that source power supply frequency is 50Hz, and the intermediate frequency of output 150Hz, 450Hz, 750Hz, in the situation that source power supply frequency is 60Hz, exports the intermediate frequency of 180Hz, 540Hz, 900Hz.In addition, can consider to use universal frequency converter, be that V, output frequency are F if establish output voltage, and universal frequency converter conventionally forms and changes in the certain mode of V/F=.Therefore, if utilize increase and decrease output to carry out control overhead temperature, become frequency and always along with the variation of voltage, change, nonmagnetic metal part and magnetic metal part are along with the variation vibration of frequency also becomes violent.On the other hand, the 3N frequency multiplication generator of transformer mode, frequency is always certain, is the control mode that only changes output voltage, and the vibration causing because of frequency variation of nonmagnetic metal part and magnetic metal part is little, to processing, can not produce baneful influence.
In addition, the present invention also provides a kind of induction heating type processing method, to clip the mode of machined object, nonmagnetic metal part and magnetic metal part are set, with respect to described nonmagnetic metal part, induction coil is arranged on to a side contrary with described magnetic metal part, by the magnetic flux that makes to be produced by induction coil, connect described nonmagnetic metal part and pass through the inside of described magnetic metal part, heat described nonmagnetic metal part and described magnetic metal part, thus described machined object is processed.
In addition,, in described induction heating type processing method, preferably, the frequency that makes to be applied to the alternating voltage on described induction coil is 50Hz～1000Hz, by described frequency, controls the heating ratio of described nonmagnetic metal part and described magnetic metal part.
In addition, in the past for processed foods such as frozen food, to in the situation that process with barbecue pattern such food on the two sides of described processed food, such as the heating surface that makes a face with cooking apparatuss such as pans, contact and roast, then food is turned over and makes another face contact and roast with heating surface.
In the situation that as described above in the mode of one side one by one to food barbecue, need the time for each one side is roasted, process time is elongated, working (machining) efficiency is bad.Described problem is along with the manufacture of processed food increases and becomes more remarkable.
In addition, as shown in patent documentation (No. 2005-246052, Japanese Patent Publication communique JP), disclose a kind of food processing apparatus, upside and the downside both sides of food, be provided with the heaters such as heater, the two sides of food has been roasted simultaneously.
, if heater is set respectively upside and the downside both sides of food, there is following problems: not only can cause foods heat unit to maximize, and can make the efficiency of heating surface worsen, environment temperature raises, and operability is also subject to baneful influence.
In addition, in the past as for industrial in a large number, the heating means of fried flour class or rice etc. continuously, use gas-heated method, vortex flow heating and overheating steam method etc.
Although gas-heated method has advantages of that firing rate is fast, cost is low, does not break away from following problems: cause burning because having forgotten to close; Because extinguishing, because of the gas leakage of use equipment, cause the danger of gassing, blast in the use with little fire.Although vortex flow heating does not have the danger of gassing and blast, shortcoming is that firing rate is slow, unit power consumption is high.Although overheating steam method electric heating is good, excellent heating means, but exist because of steam hammer cause the possibility of noise and device damage, because of the corrosion of pipe arrangement and equipment or freeze to cause the possibility damaged, while using, there is the shortcoming aspect fail safe and repair and maintenance in large-scale foodstuff manufacturing device.
Even if utilize in addition any one described method to be all difficult to strictly control heating-up temperature or heat penetration.
On the other hand, used in recent years the Domestic heating cooking apparatus of the induction heating of high frequency to be popularized No. 3446507th, Japanese patent gazette (Te Xu (for example with reference to)).Described method is not used naked light, cooking apparatus itself is heated, so fail safe is good, efficiency is also high.
, the large-scale high-frequency induction heating apparatus using on the foodstuff manufacturing device of large-scale industry, need to be together with equipment special ordering apparatus and power supply are very expensive.In addition, in induction heating method, the length of penetration of heat is several microns of left and right of utensil wall, is difficult to use for the thick cooking apparatus using in payable food manufacturing.In addition, in the situation that utilize the induction heating equipment of high frequency, because of the problem of power loss can not aggrandizement apparatus main body and power supply between distance.This at the production line that there is complexity and need to reset according to product, use in the food manufacturing factory of large water gaging, be fatal shortcoming, therefore so far can not be for large-scale foodstuff manufacturing device.
Therefore, the invention provides a kind of induction heating type food processing apparatus, can not make device maximize, the efficiency of heating surface is high, can not damage operability, can cook in a large number and continuous cooking, can prevent heating inequality, material damage, burn, and can to the both sides of food, apply heat, safe, maintaining of equipment managed easily simultaneously.As described induction heating type food processing apparatus, can enumerate following induction heating type food processing apparatus: it comprises the first container parts consisting of conductivity nonmagnetic material and the second container parts that consist of magnetic, described the first container parts and described second container parts form food receiving space, and described food receiving space is accommodated heated food; And induction coil, with respect to described the first container parts, be arranged on a side contrary with described second container parts, the magnetic flux being produced by described induction coil connects the wall relative with described induction coil of described the first container parts and by the inside of described second container parts, described the first container parts and described second container parts are heated thus.
In addition, the invention provides a kind of described food and connect frying apparatus, it comprises: the first container parts consisting of conductivity nonmagnetic material and the second container parts that consist of magnetic, described the first container parts and described second container parts form food receiving space, and described food receiving space is accommodated heated food; And induction coil, with respect to described the first container parts, be arranged on a side contrary with described second container parts, the magnetic flux being produced by described induction coil connects the wall relative with described induction coil of described the first container parts and by the inside of described second container parts, described the first container parts and described second container parts are heated thus.
In addition, the invention provides a kind of induction heating type food-processing method, food is housed in food receiving space, the first container parts consisting of conductivity nonmagnetic material and the second container parts that consist of magnetic form described food receiving space, with respect to described the first container parts, in a side contrary with described second container parts, induction coil is set, by the magnetic flux that makes to be produced by induction coil, connect the wall relative with described induction coil of described the first container parts, and by the inside of described second container parts, heat described the first container parts and described second container parts, thus described food is processed.
According to described scheme, food is housed in the food receiving space that the first container parts consisting of conductivity nonmagnetic material and the second container parts that consist of magnetic form, induction coil is arranged on to a side contrary with second container parts with respect to the first container parts, make the magnetic flux that produced by induction coil connect the first container parts of conductivity nonmagnetic material, so can heat the first container parts.In addition, because the magnetic flux being produced by induction coil passes through the inside of the second container parts of magnetic after connecting the first container parts, so can heat second container parts.Thus, can utilize the first container parts and second container parts to heat the food being housed in food receiving space.In addition, owing to only in the first container parts side, induction coil being set, so can not make device maximize, can simplify switching and the mounting or dismounting of lid, therefore taking out or put into food becomes easy.In addition,, owing to utilizing induction heating to heat the first container parts and second container parts, so the efficiency of heating surface is high, can not damage operability.In addition, not only can cook in a large number and continuous cooking, also can prevent that heating is uneven, can prevent material damage, burn.Thus, can improve mouthfeel, local flavor, the outward appearance of food, can boost productivity.
In addition, the present invention has used the induction heating of intermediate frequency to be applied to large-scale continuous food heater by handle, can high accuracy controls heating-up temperature and heat penetration, can be selectively, strongly, in short time objective food is heated.Because using intermediate frequency to cause induction heating, can make the length of penetration of heat be deep into 10mm left and right, also can tackle thus the thick cooking apparatus of using in food manufacturing.
In addition, compare with high frequency, the power loss of intermediate frequency situation is little, so can increase the distance apart from power supply.Can keep thus that heating control precision as induction heating advantage is high, fail safe good, energy efficiency is high, and can become at the on-the-spot device that can use of food manufacturing.
In addition, by the short time and to position laser heating cooking food selectively, can prevent that heating is uneven and burn, simplify the refrigerating work procedure after heating, the load of reduction freezing equipment, because having shortened time-consuming heating refrigerating work procedure, can increase substantially productivity ratio.By only short time heating being carried out in the position of needs, can prevent that unnecessary heat from distributing the deterioration of the unnecessary thermal loss causing and the operating environment causing thus towards periphery, can reduce the energy of use.
In addition, in the situation that using the present invention to carry out heating cooking to food, can prevent the loss of flavor component outside food and because of waste heat cause aging, the luxury food of having given objective food desirable barbecue pattern and barbecue smell can be provided.
Specifically, preferably, described the first container parts is the food containers with peristome, and described peristome is opening upward, and described second container parts are lids, and described lid seals the described peristome of described food containers.In this case, induction coil is located at the diapire below of food containers.In addition, for the diapire to food containers rightly heats, preferably, the wall relative with induction coil in food containers diapire is roughly plate shaped, and the magnetic flux being produced by induction coil is the vertical food containers that connects substantially.
At this, because the inductive current direction that flows through the electric current of induction coil and produce in the first container parts and second container parts is contrary, effect has the power (repulsive force) of mutual repulsion, sometimes produces the problem of second container parts accidental.In order to solve described problem, preferably, magnetic circuit is arranged on the central portion of described induction coil with iron core.By the central portion at induction coil, magnetic circuit iron core is set, this magnetic circuit flows through the magnetic flux of equidirectional with the thickness direction of iron core and second container parts, so produce the power (attraction) attracting each other.Therefore, induction coil, and the first container parts and second container parts between as can not acting on large repulsive force with joint efforts, can prevent second container parts accidental.
Preferably, be provided with the magnetic flux path being formed by magnetic and form member, described magnetic flux path forms outside circumference and described induction coil and the face contrary side of described the first container parts that member covers described induction coil, forms the magnetic flux path that the magnetic flux that produced by described induction coil passes through.According to this scheme, be formed with following magnetic circuit: the magnetic flux being produced by induction coil connects the first container parts, through food receiving space, arrive second container parts, by behind the inside of these second container parts, flow to magnetic flux path and form member.Its result, can be effectively the magnetic flux being produced by induction coil lead the first container parts and second container parts.
Preferably, described the first container parts forms member supporting by described magnetic flux path.According to this scheme, can form the structure that member forms supporting the first container parts by magnetic flux path, can simplification device structure.
Preferably, with respect to described second container parts, in described the first container parts one side, conductivity nonmagnetic material is adjacent to and is arranged on described second container parts.Like this, if conductivity nonmagnetic material is adjacent to the inner side that is arranged on second container parts, induced current flows and produces heat in conductivity nonmagnetic material, can make to be risen by the temperature that is adjacent to the conductivity nonmagnetic material of setting and the second container parts that magnetic forms.In addition, resistivity, the thickness of the conductivity nonmagnetic material being adjacent to by selection, can adjust the temperature rising value of second container parts.In addition, so-called conductivity nonmagnetic material is such as being non-magnetic stainless steel, copper etc.

Because the arranged outside in the first container parts one side has induction coil, so the heat dissipation capacity from the first container parts is few, the outside of second container component side is opened wide, many from the heat dissipation capacity of second container parts, along with second container parts become high temperature, specific temperature rise reduces.In order to solve described problem, preferably, thermal insulation member is arranged on a side contrary with described the first container parts with respect to described second container parts.
At this, in the situation that make to be applied to the frequency of the alternating voltage on induction coil, be the low frequency that is less than 50Hz, the first container parts consisting of nonmagnetic material is difficult to be heated, and in addition, the magnetic flux density of second container parts is too high and saturated.On the other hand, in the situation that make described frequency for surpassing the high frequency of 1000Hz, the first container parts consisting of nonmagnetic material, by superheated, is compared temperature with second container parts and is become too high.Therefore, preferably, the frequency that is applied to the alternating voltage on described induction coil is 50Hz～1000Hz, by described frequency, controls the heating ratio of described the first container parts and described second container parts.
In addition,, because the first container parts is nonmagnetic material, so electric current permeability is high, interior outside is all heated.On the other hand, because second container parts are magnetics, so be that 500Hz, temperature are under 300 ℃ of conditions in frequency, electric current permeability is in about 2mm, because the face of the inner side with Food Contact is heated, so high to the efficiency of food processing.
In addition, preferably, the power supply that described induction coil is applied to alternating voltage is the 3N frequency multiplication generator of transformer mode, and wherein, N is more than 1 odd number.At this, 3N frequency multiplication generator is in the situation that source power supply frequency is 50Hz, and the intermediate frequency of output 150Hz, 450Hz, 750Hz, in the situation that source power supply frequency is 60Hz, exports the intermediate frequency of 180Hz, 540Hz, 900Hz.In addition,, although can consider to use universal frequency converter, when establishing output voltage and be V, output frequency and being F, universal frequency converter changes in the certain mode of V/F=conventionally.Therefore, if export control overhead temperature by increase and decrease, frequency always changes along with the variation of voltage, and the first container parts and second container parts are along with the variation of frequency produces high vibration.On the other hand, the 3N frequency multiplication generator of transformer mode, frequency is always certain, is the control mode that only changes output voltage, and the vibration causing because of frequency variation of the first container parts and second container parts is little, and the baneful influence that food processing is brought is little.

The induction heating test result that represents the food processing apparatus 100 of present embodiment below.
It is that thickness of slab is that SUS304, the lid of 1.5mm is that thickness of slab is that the SS400 of 2.3mm is, in the situation that the weight ratio that the distance of the face of the downside of the bottom surface of pan and lid (hereinafter referred to as gap) is 17mm, pan and lid is 1:1.045 that Fig. 3 is illustrated in pan, the frequency that makes alternating voltage is 150Hz, while thermal insulation member not being set on lid, the test result of the temperature-raising characteristic of pan and lid.
On the other hand, Fig. 4 is illustrated in the situation of Fig. 3, while being provided with thermal insulation member on lid, and the test result of the temperature-raising characteristic of pan and lid.
As shown in Figure 3, in the situation that thermal insulation member is not set, the pan temperature-raising characteristic initial with lid is identical, if but lid becomes high temperature, and the quantitative change of dispelling the heat is large, and the temperature of lid produces and reduces.On the other hand, as shown in Figure 4, in the situation that being provided with thermal insulation member, the insulated member of initial heat absorbs, and occurs making lid to be difficult to the phenomenon heating up, but along with the process of time, once after thermal insulation member is heated, lid and pan become identical temperature.
It is that thickness of slab is that SUS304, the lid of 1.5mm is that thickness of slab is in the SS400 of 3mm, weight ratio that gap is 17mm, pan and the lid situation that is 1:1.451 that Fig. 5 is illustrated in pan, making alternating current voltage frequency is 450Hz, while thermal insulation member not being set on lid, the test result of the temperature-raising characteristic of pan and lid.
On the other hand, Fig. 6 means in the situation that pan is thickness of slab is that SUS304, the lid of 1.5mm is that thickness of slab is that the SS400 of 3mm, the weight ratio that gap is 17mm, pan and lid are 1:1.451, making alternating current voltage frequency is 150Hz, while thermal insulation member not being set on lid, the test result of the temperature-raising characteristic of pan and lid.
In addition, Fig. 7 means in the situation that pan is thickness of slab is that SUS304, the lid of 1.5mm is that thickness of slab is that the SS400 of 5.8mm, the weight ratio that gap is 17mm, pan and lid are 1:2.746, making alternating current voltage frequency is 150Hz, while thermal insulation member not being set on lid, the test result of the temperature-raising characteristic of pan and lid.
From Fig. 5 and Fig. 6, can distinguish, because alternating current voltage frequency difference causes the heating of the lid of magnetic system and the pan of non magnetic system than changing.In this case, under frequency 150Hz condition, the temperature-raising characteristic of pan and lid is substantially identical.In Fig. 6, in high-temperature area, the temperature step-down of lid is because the heat radiation quantitative change of lid is large.
In addition, as shown in Figure 7, due to the heating of pan and lid than also because of their different change of weight ratio, so think that limit considers the weight ratio of pan and lid, limit their heating ratio of use FREQUENCY CONTROL.
In addition, according to described result of the test, think, in the situation that the weight of pan is made as to 1, the weight that is pan as the pan of food containers 2 and the weight ratio of lid 3: weight=1.0:0.5～3.0th of lid, suitable.
In magnetic circuit, the magnetic resistance of the nonmagnetic material layer between the thickness of slab of the pan that comprises non magnetic system and pan and lid (food receiving space S) is large.Therefore, the magnetic flux of the lid of magnetic system is difficult to saturated, gets over attenuate, loss of weight, and programming rate is faster.If the weight ratio of pan and lid is set as to 1.0:1.0～1.5, the temperature that heats up equates substantially.At this, for make to heat up temperature substantially equal weight ratio have certain scope be due to the thing because holding causes the distance of pan and lid can be slightly different, with the thickness of lid and pan, adjust.In addition, think according to the kind of the material of the control of frequency, thermal insulation member, thickness of slab etc., can for make to heat up temperature substantially equal weight ratio in the scope of half (0.5) to 3 times (3.0) left and right from it, adjusting.

In addition, owing to comparing with high frequency, the power loss of intermediate frequency situation is little, can increase the distance apart from power supply.Thus, can keep that heating control precision as induction heating advantage is high, fail safe good, energy efficiency is high, and can become the device that can utilize in food manufacturing scene.
In addition,, by with the short time and to position selectable mode laser heating cooking food, can prevent that heating is uneven and burn, can simplify the refrigerating work procedure after heating, the load of freezing equipment can be reduced, by shortening heating refrigerating work procedure consuming time, productivity ratio can be increased substantially.By only the position of needs being carried out the heating of short time, can prevent the deterioration because of distribute heat causes towards periphery unnecessary thermal loss and the operating environment that causes thus, can reduce the energy of use.
In addition, in the situation that use 100 pairs of food of induction heating type food processing apparatus of present embodiment to carry out heating cooking, can prevent the loss of flavor component outside food and because of waste heat cause aging, can provide and make objective food with the luxury food of desirable barbecue outward appearance and barbecue smell.
In addition, the invention is not restricted to described execution mode.
For example, except 3N frequency multiplication generator, can also use frequency converter and saturable reactor to form power supply.Specifically, the alternating voltage by frequency converter output certain voltage, certain frequency accesses saturable reactor and carries out Current Control between frequency converter and induction coil 4.Thus, can reduce the load vibration causing because of frequency variation.Use saturable reactor because: with semiconductor element control high frequency, be difficult technically, and cost being high, be not to utilize magnet etc. to carry out ON/OFF control, but proportion of utilization integral control can be carried out high accuracy control.
In addition, nonmagnetic metal can be shown consideration for and to be tightly arranged on the face of inner side mold, bed die one side of magnetic metal body.By like this nonmagnetic metal being shown consideration on the face of the inner side be tightly arranged on mold, induced current flows and produces heat in nonmagnetic metal body, can make by being adjacent to the nonmagnetic metal body of setting and the temperature of the mold that magnetic metal body forms raises.In addition, by selection, be adjacent to resistivity and the thickness of the nonmagnetic metal body of setting, can adjust the temperature rising value of mold.
In addition, as shown in Figure 8, the in the situation that of producing temperature inequality in nonmagnetic metal part, between nonmagnetic metal part 2 and insulation and thermal insulation member 8 and the lower part of the temperature of nonmagnetic metal part 2 (be positioned at the top of fixed screw 7 and imbed the part of nonmagnetic metal part 2 in this figure), also can be adjacent to the nonmagnetic material 62 that resistivity is lower than nonmagnetic metal part 2 is set.The nonmagnetic material 62 of described low-resistivity is such as consisting of the gold-plated grade of copper.According to this scheme, induced current easily flows at the configuration position of nonmagnetic material 62, and caloric value increases, and temperature raises, so it is uneven to eliminate the temperature of nonmagnetic metal part 2.In addition, the nonmagnetic material 62 of described low-resistivity can be by not having the heat conduction component representing to be configured on nonmagnetic metal part 2 yet in figure.
In said embodiment, using the first container parts 200 as food containers, using second container parts 300 as lid, but can be also contrary structure, be about to the first container parts 200 as lid, using second container parts 300 as food containers.In addition can be also that the first container parts 200 and second container parts 300 are all as the food containers with the resettlement section of accommodating food.
In addition, also conductivity nonmagnetic material can be adjacent to and be arranged on the face of the inner side of food containers one side of the lid of second container parts.By like this conductivity nonmagnetic material being adjacent on the face of the inner side that is arranged on lid, induced current flows and produces heat at conductivity nonmagnetic material, can make by being adjacent to the nonmagnetic material of setting and the temperature of the lid that magnetic forms raises.In addition, resistivity and the thickness of the conductivity nonmagnetic material being adjacent to by selection, can adjust the temperature rising value of lid.
