The specific embodiment
(the 1st embodiment)
In order to explain the present invention in more detail, with reference to the accompanying drawings to its explanation.Fig. 1 to Figure 20 represents the 1st embodiment of heating device involved in the present invention.Fig. 1 represents the outward appearance of this heating device 1 by stereogram.On furnace wall 2, the door 3 that forwards rotates and open is installed in front as the outline of heating device 1.Door 3 top becomes guidance panel 5, and the display 7 of the process situation of the console switch 6 of setting heating condition and display setting content, the cooking is installed.
Fig. 2 observes inner stereogram with door 3 dismountings from back side oblique upper with furnace wall 2.Fig. 3 is the stereogram of oblique this state of beneath from the place ahead.Central portion in furnace wall 2 is equipped with the cooking room 10 of case shape of door 3 side openings on lower frame 11.Cooking room 10 is except bottom parts described later, and all the conductive material by shield microwaves constitutes.
The thermal source box of taking in as the heater 12 of the 1st thermal source (heater formula thermal source) 14 is installed on cooking room 10, thermotropism source capsule 14 is installed at its rear sends into the hair-dryer 15 of circulating air, the blower motor 16 that drives hair-dryer 15 is installed above it.Constitute hot blast generating apparatus 18 by heater 12, thermal source box 14, hair-dryer 15, blower motor 16.
Be provided with in the outside of the right side wall of observing from door 3 sides of cooking room 10 and be used to make the hot blast that has passed through cooking room 10 to return the right hot blast recurrent canal 20 of hot blast generating apparatus 18, be provided with left hot blast recurrent canal 21 in the outside of left side wall for identical purpose.Top outside the back side of cooking room 10, the downside of hair-dryer 15 are equipped with the hot blast that makes the hot blast interflow of having passed through right hot blast recurrent canal 20 and left hot blast recurrent canal 21 return hair-dryer 15 and return collecting fitting 22.
Return the downside of collecting fitting 22 at the outside, the back side of cooking room 10, hot blast, be equipped with and take in as the microwave generating apparatus 24 of the 2nd thermal source and the control cabinet 27 of control device 26.At the downside of cooking room 10, be equipped with and direct near the waveguide pipe 28 of central authorities of the base plate the inside of cooking room 10 by the microwave that microwave generating apparatus 24 takes place.
Fig. 4, Fig. 5 represent that by ideograph the flowing of hot blast in the heating device 1, Fig. 4 represent flowing in the section of top view, flowing in the section that Fig. 5 represents to observe from right side wall.The circulated air that is produced by hair-dryer 15 is blown in the thermal source box 14 that is installed in cooking room 10 tops by level.In thermal source box 14 with the mobile identical horizontal direction of the circulated air that is blown on the heater 12 of a plurality of U word shapes as the 1st thermal source is installed side by side.Thereby circulated air and 12 heat exchanges of these heaters become hot blast.
At the downside of the part that heater 12 is installed, it is dividing plate 30 heater 12 and column direction that the flow restriction that is used for circulated air is installed.Fig. 6 is a stereogram of observing thermal source box 14 from downside.The downside of dividing plate 30, become opening 31 with the part that contacts below of thermal source box 14.Thermal source box 14 utilizes the flange 32 on the periphery that is arranged on opening 31 and is fixed on the ceiling 33 of cooking room 10.Under the state that is fixed with thermal source box 14, between the ceiling 33 of cooking room 10 and dividing plate 30, formed the space 35 that circulated air is passed through.The circulated air that finishes heat exchange with heater 12 becomes circulating air and curls up the space 35 that enters under the dividing plate 30.
On the ceiling 33 of cooking room 10, be provided with circulating air is ejected into a plurality of nozzle bores 37 in the cooking room 10.The circulated air that is produced by hair-dryer 15 is stronger the flowing of blast, and the circulating air that rotates under the dividing plate 30 becomes high speed jet and is ejected in the cooking room 10 from nozzle bore 30.
In cooking room 10, be horizontally installed with the refractory slab 40 that mounting is cooked product 38 by the lower part in the space.The hot blast of the high speed jet that sprays from nozzle bore 37 collides on the heating object 38, discharges its heat energy of possessing with heating object 38 heating.Make hot blast blow to by cooking product on and under the situation of heating, if making to blow to by the wind of the cooking on the product is made as high speed then the bigger raising of heet transfer rate, it is well-known that this collides hot transmission technology as jet flow.The heating device 1 of present embodiment is used this jet flow and is collided hot transmission technology.
In the hole 41 (simultaneously with reference to Figure 11) that is provided with on the refractory slab 40 in a plurality of perforation tables.The hot blast that collides on the heating object passes through the lower side space that this hole 41 flows into refractory slabs 40.On the right side wall of cooking room 10, more be provided with right hot blast suction inlet 42, be provided with left hot blast suction inlet 43 in the position of the correspondence of left side wall by the lower part in installation site than refractory slab 40.Flow into the circulating air of the lower side space of refractory slab 40, flow into by the hot blast suction inlet about these 42,43 left and right sides sidewall that is arranged on cooking room 10 the outside about hot blast recurrent canal 20,21.The outside plate of cooking room 10 sides of right hot blast recurrent canal 20 and left hot blast recurrent canal 21 communicates with the outside plate of the left and right sides sidewall that constitutes cooking room 10.That is, the outside plate that constitutes the left and right sides sidewall of cooking room 10 play separate in the cooking room 10 and about the effect of dividing plate of hot blast recurrent canal 20,21.
The hot blast that right hot blast recurrent canal 20 and left hot blast recurrent canal 21 are communicated in the downside that is installed in hair-dryer 15 jointly returns collecting fitting 22.The rising in these pipes of the circulating air of the hot blast recurrent canal 20,21 about inflow flows into hot blast then and returns interflow in the collecting fitting 22.Hot blast returns collecting fitting 22 and is communicated in hair-dryer 15, and the circulating air behind the interflow is inhaled in the hair-dryer 15.Then, quickened by hair-dryer 15 once more, increase blast and be blown into then in the thermal source box 14.
Hot blast increases flow velocity by hair-dryer 15, circulates in such runner repeatedly.Thereby hot blast contacts with heater 12 and obtains heat energy in this process, with 38 collisions of the quilt cooking product time this heat energy is passed to by cooking product 38.Be heated from the surface by cooking product 38 thus.
The heating device 1 of present embodiment is cooked product by circulating air from surface heating quilt, and merging uses microwave to heat internally.Microwave is taken place by the microwave generating apparatus 24 of the back side outer lower portion that is configured in cooking room 10, and the waveguide pipe 28 of the downside by being installed in cooking room 10 is led near the central authorities (with reference to Fig. 5) of the base plate the inside of cooking room 10.The base plate 50 of cooking room 10 is made by dielectric substances such as the pottery that microwave is passed through, glass.Side is equipped with the rotable antenna 53 that is driven by motor 52 rotations below base plate 50.Microwave is stirred by rotable antenna 53 reflections, sees through base plate 50.Like this microwave is not shone in the cooking room 10 widely unevenly.Thereby being absorbed this microwave by cooking product 38 also is heated internally.
Next, the structure for the heater 12 in the thermal source box 14 describes.Fig. 7 is the easy stereogram of understanding of configuration state that thereby the part dismounting of the outside plate of thermal source box 14 is made heater 12.Each heater 12 is made as the structure of the discoideus fin 55 that a plurality of heat exchanges that are used to improve itself and circulating air have been installed as shown in Figure 8 around the sheath heater 56 that forms the U word shape.At the two ends of sheath heater 56 heater terminal 57 is installed.
In thermal source box 14, be that 6 these root heaters 12 equally spaced are installed on the horizontal direction side by side at the flow direction of the circulating air that blows out from hair-dryer 15.6 heaters 12, be positioned at every 1 its heater terminal 57 with respect to the mode of the direct of travel left and right sides opposition side of circulating air install opposite (with reference to Fig. 7) mutually.Can carry out same heat exchange in direct of travel left and right sides both end sides thus.
In addition, 6 heaters 12 make U literal (face that comprises the sheath heater 56 of U word shape) tilt with respect to the direct of travel of circulating air, thereby and every 1 the position are misplaced on above-below direction to be staggered.Fig. 9 is the cutaway view of the appearance of its installation of explanation.That is, make on the direction vertical, the misplace outside dimension d of above-mentioned fin 55 of the odd number root heater and the position of even number root heater with the direct of travel of circulating air.And then, all heaters 12 are mounted to the literal direct of travel tilt angle theta with respect to circulating air of its U, the periphery that this angle θ is made as the fin 55 of heater adjacent when the approach axis of circulating air is observed seems the angle that overlaps.
Be made as d at the outside dimension with fin 55, when the interval of 55 of the fin of the U word shape portion of heater 12 was made as k, this angle θ calculated according to following relational expression.
d＝k·sinθ
If 6 heaters 12 are installed like this, then from the approach axis of circulating air to heater 12 and column direction when observing, the periphery that becomes the fin 55 of adjacent heater seems the state that overlaps.Under this state, do not carry out heat exchange with fin 55 and the amount of the hot blast that passes through by minimization.In addition, it is very big that the pressure loss of hot blast does not become yet, so can carry out the heat exchange of circulating air and 6 heaters 12 effectively.In addition, by the adjustment of resistance value, the caloric value of 6 heaters 12 diminishes to outlet side from the entrance side of thermal source box 14, prevents the overheated of downstream heater.
Next, the configuration relation for a plurality of nozzle bores 37 on the ceiling 33 that is arranged on cooking room 10 for circulating air being ejected in the cooking room 10 describes.Figure 10 is the figure of an example of expression shape of nozzle bore 37 and arrangement.In this embodiment the section shape of nozzle bore 37 is made as the circle of diameter B.Be arranged as staggered clathrate, will be with equal line space Q (=3 on the longitudinal direction of 1 row nozzle bore 37 that is provided with the interval S that equates in a lateral direction of figure at figure
1/2S/2) dispose and be configured to every the 1 row S/2 that misplaces in a lateral direction.If arrange like this, then in the delegation adjacent 2 nozzle bores 37 with in the middle of the horizontal direction position is positioned at it and nozzle bore 37 distance between centers separately that belongs to adjacent row all become and equate with nozzle installing space S, these 3 nozzle bores 37 become and are positioned at the summit that the length of side is the equilateral triangle of S.
Known: from below with microwave irradiation to the ceiling 33 of the steel plate system of the nozzle bore 37 that is provided with such arrangement the time, the attenuation A of the microwave by ceiling 33 front and back can represent by following formula approx.
A＝20log
10(1.5S·Q·λ/(π·B
3))+32t/B [db]
Here, t is the thickness of slab of ceiling 33, and λ is the wavelength of microwave.
In the microwave that the base plate 50 that has passed through cooking room 10 shines, the microwave that being cooked product 38 does not have to absorb arrives ceiling 33.For prevent microwave in nozzle bore 37 by leak into cooking room 10 above, must set in advance the value of B, S, t, so that the attenuation A that calculates by following formula becomes big.For example, nozzle bore diameter B is being made as 20mm, nozzle installing space S is made as 40mm, thickness of slab t is made as 0.5mm, wavelength X is made as 120mm when (being equivalent to frequency 2450MHz), the value of attenuation A becomes 20db, can decay to below 1/100th.At this moment, the 20mm of nozzle bore diameter B is equivalent to 1/6th of wavelength X, and the 40mm of nozzle installing space S is equivalent to 1/2nd of wavelength X.
Next, the structure of being cooked the refractory slab 40 of product 38 for mounting describes.On refractory slab 40, be provided with a plurality of holes 41 as shown in figure 11.This hole 41 is used to make from the nozzle bore 37 of ceiling 33 and sprays and collide the downside that is flow to refractory slab 40 by the circulating air after on the cooking product 38.In addition, seen through the microwave that base plate 50 shines and be positioned in being absorbed on the refractory slab 40 owing to making, so the dielectric substance making that base plate 50 is seen through easily by microwave by cooking product 38.
The heating device 1 of present embodiment is used jet flow and is collided hot transmission technology to being carried out the surface heating by cooking product 38.In this jet flow collision heat transmission, must pass to efficiently by cooking product 38, so must suitably set configuration and the nozzle bore 37 and the distance of being cooked product 38 of nozzle bore 37 in advance from the heat energy that hot blast had that nozzle bore 37 sprays.
Figure 12 is that model utility ground expression makes jet flow collide the figure of the mobile form of the jet flow by on the cooking product 38 time of leaving that distance H ground places from 1 nozzle bore 37.The form that flows is according to the place and difference, but can think and be divided into 4 approximately following zones.The 1st zone is the zone of leaving after the nozzle bore 37 that is called as territory, potential core 39, in this zone, the area of section of the area of section of jet flow and nozzle bore 37 about equally, flow velocity also with the interior flow velocity of nozzle bore 37 about equally.
The 2nd zone is the zone that is called as free jet zone 39a that links to each other with the 1st zone, and in this zone, jet flow enlarges gradually, and the area of section also constantly increases, and opposite flow velocity is slack-off gradually.The 3rd zone is that jet flow collides the regional 39b of collision jet that is formed by cooking product 38, thereby jet flow touches on the cooking product 38 to be passed to heat energy by cooking product 38, and the direction that flows is become and the surperficial parallel direction of being cooked product 38.With nozzle bore 37 under contact by the more weak stationary point 59 of near surface generation flow velocity of cooking product 38.In the time will being made as H from the distance of nozzle bore 37 till the surface of being cooked product 38, it is the discoid of radius centered 0.35H, height 0.2H～0.3H that collision jet zone 39b becomes with stationary point 59.
The 4th zone is the zone that is known as wall jet flow zone 39c that produces in the outside of collision jet zone 39b, and jet flow flows abreast with the surface of quilt cooking product 38, and flow velocity is slack-off along with leaving stationary point 59.From the jet flow that nozzle bore 37 sprays, will collide by the surface of cooking product 38 and the hot blast that flow velocity descends forces back, contact with the surface of being cooked product 38 successively.Like this, the heat energy that jet flow had is passed to efficiently by cooking product 38, and being cooked product 38 is heated rapidly.
Above-mentioned explanation is that nozzle bore 37 is 1 a situation.Relative therewith, when being provided with a plurality of nozzle bore 37 shown in present embodiment, 37 a plurality of jet flows of spraying produce and interfere from the adjacent nozzles hole, so the metamorphosis that flows.Figure 13 be expression with the distance between centers S of 2 nozzle bores 37 set the figure of the form that flows of the jet flow during broad.Thereby on colliding by cooking product 38, discharge in the hot blast that the heat energy temperature descends, the hot blast that flows to the direction of adjacent jet flow produces interference mutually and rises.Thereby mixing with the jet flow of the high temperature that newly spray from nozzle bore 37 then descends its temperature.
Not only the efficiency of heating surface descends when producing such phenomenon, thereby and collide by the impact strength on the cooking product produce bigger inequality evenly heating become difficult.In order to prevent this situation, importantly distance between centers S and the distance H from nozzle bore 37 to the surface of being cooked product 38 are redefined for suitable value, so that the hot blast after the collision can not turn back to nozzle bore 37 sides.
Figure 14 is that model utility ground expression is placed by the figure of the mobile form of the jet flow during from 3 nozzle bores, 37 ejection hot blasts under the state of cooking product 38.Produce mutually between adjacent jet flow and interfere, the flow velocity of the major part of jet flow and direction are shown in the arrow among the figure.Distinctive flow velocity is the flow velocity on the Y line of drawing downwards of the centre position O from 2 nozzle bores 37.Flow velocity on the Y line changes significantly according to the distance of distance centre position O.The flow velocity of the concentrated area 58 shown in the figure demonstrates the higher value towards centre position O in the wider scope that with the Y line is the center.
On the Y line, along with leaving, weaken towards the flow velocity of centre position O from middle position O, merging point 58a in the drawings, flow velocity is almost 0.There is flow velocity part faster at this merging point 58a in the positive lower part of each nozzle bore 37.
On the Y line so that binding site 58b from the figure that middle position O leaves, 2 the adjacent flow velocitys that exist at merging point 58a part zoarium faster are one.And to become with the Y line be the downward flow velocity liquid stream faster at center.After this,, only there is downward flow velocity part faster, do not have flow velocity part towards centre position O in the part that with the Y line is the center at the calmodulin binding domain CaM 58d that is positioned at this binding site 58b downside.
For stronger hot blast is collided by on the cooking product 38 and can not make the hot blast after the collision flow to ceiling 33 sides as shown in figure 13, as long as will be cooked the calmodulin binding domain CaM 58d that product 38 be placed on the binding site 58b downside among Figure 14.As everyone knows, the distance y cp from nozzle bore 37 to binding site 58b can represent by following empirical formula.
ycp＝3.514B·(S/B)
0.673
For example, be made as 20mm at diameter B, when the distance between centers S of 2 nozzle bores 37 is made as 20mm, become 110mm to the distance y cp of binding site 58b with nozzle bore 37.In the present embodiment, become the installation site of determining refractory slab 40 by the mode of following formula calculated distance ycp with ceiling 33 and by the distance between the surface of cooking product 38.So, collide by the hot blast that returns afterwards on the cooking product 38 and tail off, can improve the efficiency of heating surface to ceiling 33 directions.
Figure 15 is the figure of structure that diagrammatically represents the control device 26 of heating device 1.Control device 26, by microwave circuit part 60, heater circuit portion 61 take place, the control circuit portion 62 that controls these circuit parts and blower motor 16 constitutes.The circuit part that circuit part 60 is to use magnetron 13 to produce the microwave of frequency 2450MHz, simultaneously the motor 52 that reflects rotable antenna 53 usefulness that stir this microwave is driven takes place in microwave.Power supply is provided by source power supply, and it opens and closes by switch 65 is opened and closed and is undertaken.Heater circuit portion 61 is circuit parts that power supply is provided to 6 heaters 12, by switch 66 source power supply is opened and closed, and controls power supply thus and supplies with.
Next, action and the effect to the heating device under such structure 1 describes.After on the refractory slab 40 that is placed on by cooking product 38 in the cooking room 10, door 3 is closed.So the switch 67,68 that opens and closes coupled switch as door becomes open mode.When source power supply is given electricity via not shown DC power supply circuit, wait pending operation input.Next, the operator via console switch 6 to control circuit 63 input cooking times, hot blast temperature (cook temperature), when being cooked the name of an article etc., move as described as follows.
When the operator used console switch 6 to cook the indication of beginning, control circuit 63 made switch 65 become open mode, made microwave that circuit part's 60 actions take place.Begin to produce microwave by magnetron 13 thus.Thereby simultaneously also begin rotation to motor 52 supply capability rotable antennas 53, the microwave that is produced passes to the downside of cooking room 10 via waveguide pipe 28, is rotated antenna 53 reflections there and stirs, and sees through base plate 50 and does not shine cooking room 10 widely unevenly.
Except switch 65, control circuit 63 makes switch 66 become open mode simultaneously, carries out power supply to heater 12 and supplies with, thereby and also provide power supply to produce circulated air via motor drive circuit 72 to blower motor 16.Thereby control circuit 63 is adjusted the opening/closing cycle of switch 66 and will be controlled to be with consistent from the design temperature of console switch 6 inputs by temperature testing organization 70 detected temperature.Blower motor 16 is by can constituting by the d.c. motor that auxiliary voltage changes rotary speed, control circuit 63 with its be adjusted into from console switch 6 inputs by the corresponding rotary speed of the cooking name of an article.
When the temperature of heater 12 rose, the circulated air that is produced by hair-dryer 15 became circulating air.Circulating air is ejected in the cooking room 10 thereby the nozzle bore 37 from the ceiling 33 that is arranged on cooking room 10 becomes jet flow as mentioned above, is cooked product 38 thereby collide by the surface of cooking product 38 from the surface heating.Collide the downside that is flowed into refractory slab 40 by the circulating air of the cooking on the product 38, the hot blast suction inlet 42,43 about being inhaled into and about hot blast recurrent canal 20,21 in pass through, in hot blast returns collecting fitting 22, collaborate then.Enter once more behind the interflow and quicken in the hair-dryer 15 and be blown in the thermal source box 14.Then from heater 12 obtain to vulcanize to and become high temperature, be injected into once more in the cooking room 10.The hot blast of high temperature collides while circulating by cooking product 38 surfaces like this, is heated rapidly from the surface by cooking product 38 thus.Base plate 50 irradiating microwaves by cooking room 10 concurrently with the heating of being undertaken by this circulating air.Thereby being absorbed this microwave by cooking product 38 is also heated internally rapidly.
Figure 16 be measure by heating device 1 cooking of present embodiment freezing during by cooking product 38 by the example of the surface of cooking product 38 and temperature inside variation.As can be known: surface and the temperature inside that finishes to be cooked product 38 in the back of thawing begins to rise rapidly jointly, cooked product 38 and is heated with inner both sides from the surface.About hot blast suction inlet 42,43 near hot blast temperatures rise gradually, be maintained design temperature thereby arrive behind the design temperature by the opening/closing cycle of adjusting heater 12.After the cooking time that such heated condition has continued to set, cut off the power supply supply that circuit part 60, heater circuit portion 61, blower motor 16 take place to microwave, thereby heating finishes.
The heating device 1 of the present embodiment that constitutes like that as mentioned above and move plays following effect, effect.
