Description

A kind of heating module

Technical field

The utility model relates to IH heating art more particularly to a kind of compact IH that can be realized inexpensive rapid cooling Heating module.

Background technique

Electromagnetic induction heating electric appliance generally includes upper cover, pedestal, coil panel and coil brace, automatically controlled mainboard, and radiator is interior Several parts such as pot.Wherein, the power device (such as IGBT) on automatically controlled mainboard (usually using PCB as form) at work, can generate A large amount of heat.In addition to power component, other electronic components on mainboard can also generate certain heat.In addition, electromagnetic induction adds Thermal modules are using alternating magnetic field caused by inductance coil disk, so that the magnetic conductivity object being placed in the magnetic field generates vortex, from And it generates heat.Therefore, when electromagnetic induction heating module works, the inductance coil disk being energized can also generate a large amount of heat, these If heat cannot be timely and effectively discharged to except electromagnetic induction heating module, it is excessively high to will lead to temperature in equipment, and then influence The normal work of device components, or even damage component.In the prior art, it will usually which wind groove formula is installed on automatically controlled mainboard Radiator, and a fan towards radiator is set, to realize the heat dissipation of automatically controlled mainboard, while the air-flow generated using fan, Take away the heat of coil sections disk generation.But existing design usually all has that heat dissipation effect is bad, and structural integrity is poor, body The problems such as product is bigger than normal.

For example a kind of electromagnetic heating electric rice cooker disclosed in CN104223930B, blower setting are utilized in coil disc side Wind path wall guides tangential gas flow to coil pan bottom, and axial flow is blowed to automatically controlled mainboard and radiator upwards.This cloth The shortcomings that setting is the air-flow for blowing over radiator, becomes the air-flow with big calorimetric, which inevitably blows over automatically controlled again The surface of mainboard affects the radiating efficiency of automatically controlled mainboard other parts, and the bottom due to the position of blower far from coil panel Portion, so the air-flow of side blowout is when reaching coil pan bottom, air quantity and wind pressure have deficiency, can not high efficiency and heat radiation.In addition, Although radiating subassembly is integrated with radiator, board design, it is still a kind of blower on the whole under, circuit board is upper Stacking layout, runner design do not take into account all heat generating components；Causing it simultaneously, size is larger in the vertical direction, and Since the position of blower is outer in coil panel projection, and the space of electric cooker bottom and side is not made full use of, caused entire The volume of radiating subassembly and automatically controlled mainboard is bigger than normal, and structure is not compact enough.

CN104042119B discloses a kind of IH rice cooker main control module and mainboard bracket, the gas that side outlet air notch 17 is blown out Stream avoids other yuan that the air-flow being heated blows to automatically controlled mainboard across radiator 21, and by the setting in air duct and baffle Part.But since its blower is still arranged in coil disc side and to shunt a part of air-flow from side notch 17, because This, side heat dissipation effect of the side airflow to coil panel far from blower of blowout is poor, and due to the setting of upper guard-plate, So that directly blowing to the other elements of automatically controlled mainboard without air-flow, cause these element radiatings still unsmooth.And it is internal due to The wind path wall to intersect vertically is excessive, and the air-flow of part axially upwards will could be blown out through multiple impacts, also results in the damage of wind pressure It loses, in actual design, it is likely that designer is forced to increase cost and noise using the blower of bigger specification.Although in addition, Radiating subassembly is integrated with radiator, board design, but is still a kind of blower on the whole under, and circuit board is in upper heap Laying up office, runner design do not take into account all heat generating components；Causing it simultaneously, size is larger in the vertical direction, and due to Motor position is partially outer, does not make full use of the space of electric cooker bottom and side, wastes a part of space, causes entire electric meal Cooker body product is bigger than normal, and structure is not compact enough.

CN107684342A discloses a kind of electric pressure cooking saucepan, although blower is mounted below coil panel, but due to it Air-flow axially upwards will also take into account the heat dissipation of automatically controlled mainboard, so, blower there is no close to coil pan bottom center and It is proximate to edge arrangement, half is located at below coil panel, and half is located at below automatically controlled mainboard.This actually still it is traditional up and down The top of blower is still arranged in stacked structure, radiator, shows no sign of using the idle space in pot；Meanwhile blower Tangential gas flow do not utilized well or the upward blowout of all one brains of air-flow, the air-flow for flowing through radiator exist Under the action of baffle 630, and the component on circuit board is blowed to, various air-flow weave ins are equivalent to secondary to component Heating, radiating efficiency are low；Further, since the electric pressure cooking saucepan uses electromagnetic heating chassis, chassis is laid in substantially below interior pot, nothing The interior pot side compared with distal side need to be directed flow into, therefore, the wind pressure and air quantity requirement to radiating airflow be not very high, so Shunting function is not just fully considered in design, and the control of air-flow is only realized using only simple baffle, essence is both not achieved Quasi- control, refraction will also result in air loss, and it is chaotic, discrete and interfere with each other to ultimately cause air-flow；Under this scheme, If cooling fin fever is acutely, temperature, wind pressure and the air quantity that refraction blows to the radiating airflow of circuit board can be insufficient, if answered In actual design for electromagnetic induction electric appliance, it is likely that designer is forced to cause volume to increase using the blower of bigger specification Greatly, noise rises, cost improves；In addition, its blower is arranged on bottom plate, power panel is arranged again in case inside, without shape The design integrally changed, causes loosely organized, has tied up the space of other structures, assembly, repair demolition have inconvenience.

CN207492536U discloses a kind of electric cooker, and blower is set to the lower section of coil panel and automatically controlled mainboard, and one Axial flow is divided to blow to coil panel, a part of air-flow blows to radiator, and it is still, unreasonable due to being laid out, cause volume bigger than normal, wind Machine apart from coil panel too far, it is also necessary to the olderly flowage that additional wind deflector is just able to achieve air-flow is set around coil panel.This Outside, Duct design is unreasonable, and the air-flow guidance for blowing to coil panel is inaccurate, necessarily causes the heat dissipation between various pieces uneven It is even；The other elements for not guiding the automatically controlled mainboard of air flow direction cause this some components can only natural heat dissipation；It is blown from radiator Hot wind out, is not expelled directly out outside shell, but also in shell body-internal-circulation, largely blow to other yuan of automatically controlled mainboard Part, causes secondary heated, results in the degradation of radiating efficiency.Although in addition, radiating subassembly and radiator, board design It is integrated, but is still a kind of blower on the whole under, circuit board is laid out in upper stacking, almost just not to air-flow progress Accurate guidance, runner design do not take into account all heat generating components；Causing it simultaneously, size is larger in the vertical direction, and Since the position of blower is most of outer in coil panel projection, and the space of electric cooker bottom and side is not made full use of, made Vertical height at entire radiating subassembly and automatically controlled mainboard is bigger than normal, and structure is not compact enough.

CN204617952U and CN207444813U discloses a kind of electric cooker, and structure is very similar, although Radiating subassembly is integrated with radiator, board design, but is still a kind of blower on the whole under, and circuit board is in upper heap Laying up office, and since the position of blower is most of outer in coil panel projection does not make full use of electric cooker bottom and side Space causes entire radiating subassembly and automatically controlled mainboard structure not compact enough.Although radiator is all disposed within blower side, Since its blower is still arranged in coil disc side and to shunt a part of air-flow from side notch, blowout Side heat dissipation effect of the side airflow to coil panel far from blower is poor, and since top baffle is whole by all axial flows It blocks, therefore blows to the air-flow on coil panel top almost without for the line of the electric cooker electric appliances side surface upper part of electromagnetic heating It is poor to enclose heat dissipation effect, while air-flow is not guided accurately, so that directly blowing to other yuan of automatically controlled mainboard without air-flow Part causes these element radiatings still unsmooth.

To sum up, it is badly in need of providing a kind of good heat dissipation effect in the market, builds at low cost, volume compact can be used as universal component Heating module.

The total thinking of the utility model is: constructing a kind of heating module, comprising: coil panel, coil brace, automatically controlled mainboard, Blower and air duct wall construction, the coil brace are main assembly parts, coil panel, automatically controlled mainboard, blower and air duct wall construction difference It is installed in the outwardly and inwardly corresponding structure of coil brace, makes full use of the idle sky of coil brace lower section and side-lower Between, not only achieved the purpose that compact-sized, and but also can guarantee good heat dissipation.

In order to better understand the above technical scheme, in conjunction with appended figures and specific embodiments to upper It states technical solution to be described in detail, it should be understood that the specific features in the utility model embodiment and embodiment are to this The detailed description of application technical solution, rather than the restriction to technical scheme, in the absence of conflict, this is practical Technical characteristic in new embodiment and embodiment can be combined with each other.

With reference to Fig. 1-3, a kind of heating module, comprising: coil panel 1, coil brace 2, automatically controlled mainboard 4, blower 5 and wind path wall Structure, the coil panel 1 are socketed on inside the coil brace 2, and the blower 5 is set under the bottom of the coil brace 2 Side, and the projection at its center is located in the projection of the coil panel 1, and the automatically controlled mainboard 4 includes circuit board 41 and radiator 42, the radiator 42 is horizontally placed on the side of the blower 5, and the circuit board 41 is vertically installed on the radiator 42 Portion, the air duct wall construction are used for air-flow from the direction of automatically controlled mainboard 4 described in 5 side guide of blower.

The coil brace 2 is main assembly parts.The projection of the blower 5 is located in the projection of the coil panel 1.It is described to dissipate The projection of hot device 42 is at least partially disposed in the projection of the coil panel 1.The projection of the circuit board 41 and the coil panel 1 It projects non-intersecting.

Herein it is so-called project refer in the depth along coil brace 2, short transverse is projected in other words, Ye Ji The projection of plane where being parallel to 2 bottom of coil brace.

The coil brace 2 substantially coats the outside of coil panel 1, and bottom is arranged jagged 21, blows out at the top of blower 5 Air-flow, the gap entered between the coil brace 2 and the coil panel 1 via the notch 21 are simultaneously expelled to outside mould group.

The bottom part down of the coil brace 2 is arranged in by center in fan installing structure 25.

The automatically controlled mainboard 4 is substantially L-shaped, the side of the port face blower 5 of 42 wind groove of radiator.

The air-flow of 5 side of the blower blowout, a part blow to the wind groove of the radiator 42；A part is dissipated by described Gap between hot 42 top of device and 2 outer surface of the coil brace blows to the circuit board 41.

The air duct wall construction further includes bracket wind path wall 23, for guiding through 42 top of radiator and the line The air-flow in gap blows to the component on the circuit board 41 between 2 outer surface of coil support, and from the bracket wind path wall 23 Mould group is discharged in portion or top.

The circuit board 41 can also be to be set on the radiator 42 relative to angle of the vertical direction less than 30 ° Portion.The radiator 42 can also be set to the side of the blower 5 with the angle relative to horizontal direction less than 30 °.

Above-mentioned this coil brace 2, blower 5, circuit board 41, radiator 42 and wind path wall arrangement, hence it is evident that difference It is arranged in traditional stacked on top, the heat dissipation of coil panel 1 should be completed by avoiding air-flow in the past axially upwards, also complete electricity The problem of mainboard 4 radiates is controlled, the difficulty of volume and assembly is substantially reduced.Creative is complete in quite compact structure space At being precisely controlled to air-flow, the air-flow of blower 5 is divided into three parts, two bursts of tangential gas flows are respectively used in automatically controlled mainboard 4 The heat dissipation of circuit board 41 and radiator 42, axial flow are used for the heat dissipation of coil panel 1 (including disk body, coil, magnetic stripe etc.), so that Three strands of air-flows possess the runner of oneself respectively, can work independently, not interfere with each other, and reduce the turbulent flow of enclosure interior, also just subtract The loss of energy is lacked.Multiply air-flow has flowed through all heat generating components in shell, and being substantially filled with has expired each space, and it goes out Road is not overlapped, so that so-called air-flow " stagnant wake " is all not present in the even entire shell of heating module, makes to own in space Air-flow all flow, and do not interfere with each other, Each performs its own functions, ties in.

Blower 5 is set to below coil panel 1 by paracentral position, can make full use of the space of 1 bottom of coil panel, because Be arranged in housing bottom surface mostly for current radiator fan air inlet, and fan height can control it is smaller, so putting Enter the lower section of coil panel 1, the thickness of electric cooker will not be obviously increased, while the width of shell side is obviously tailed off, it can also be with Say the space for increasing and other components being set.Secondly, this be arranged such that the axial air outlet range line circle disk 1 of blower 5 is close, It can be reduced as far as the loss of wind pressure, flow air-flow preferably along the gap of 1 outer surface of coil panel, preferably It radiates to entire coil panel 1.When coil brace 2 be basic cladding coil panel 1 it is closed when, this arrangement equally can be with Its advantage is played, axial flow hardly needs the guidance of any excessive parts, so that it may coil directly be blown by notch 21 Gap between disk 1 and coil brace 2, and along on the practical significance being made of magnetic stripe 26, coil 3, strip muscles and bones 12 etc. Air duct flow to rapidly the various pieces of coil panel 1, eventually passes through the air outlet discharge heating module on 1 top of coil panel.

Radiator 42 is arranged in 5 side of blower, the tangential gas flow of blower 5 is effectively utilized, and blow from radiator 42 Hot wind out is expelled directly out shell, will not blow to other 41 components of circuit board, will not generate interference with other radiating airflows, It ensure that the duration and validity of heat dissipation.Furthermore, it is generally the case that the wind guide tank meeting face blower 5 of radiator 42 is far from institute State the side at 2 center of coil brace, the port of 42 wind groove of radiator in height substantially with the side of blower 5 or lateral outlet air It is mouthful concordant, and apart from close, in this way, the tangential gas flow of blower 5 directly will enter radiator 42 with greater pressure and air quantity Wind groove improves radiating efficiency.It is, of course, preferable to mode be motor thickness and radiator thickness it is almost the same, radiating fin Piece is vertically arranged, and extending direction is consistent with airflow direction.In this way, when guiding lateral airflow, entrance that air-flow can be relatively uniform The radiating fin of radiator wind groove.As soon as further, it is also possible to a bottom plate is arranged again below radiating fin, the flowing of such air-flow Can more there be directive property.When the wind groove direction of radiator and airflow direction are inconsistent, then need additional diversion component by air-flow It can be used this with the equidirectional feeding of wind groove Mode.In addition, also it is clear that at least part of radiator 42 is in the upright projection model of coil panel 1 from attached drawing 3 In enclosing, that is to say, that the substantial portion of volume of radiator 42 is in the space in 1 side lower part of coil panel, in this manner it is possible to fill Divide the space extra using this part, this is especially advantageous for the product of electric cooker electric pressure cooking saucepan class.Also, due to radiator 42 Be it is horizontal positioned, upper cover plate separates other components of hot wind and automatically controlled mainboard 4, and also acts and be directed across sky Gap blows to the effect of the tangential gas flow of other elements, is equivalent to the effect that air duct bottom wall is additionally realized using radiator 42, into One step saves space, improves current path.Certainly, so-called be horizontally disposed with not is absolute, it should be understood that substantially water It is flat, for example be tilted within 5 ° and just belong within allowed band.As long as the space around coil brace can be made full use of, institute State the side that radiator 42 can also be set to the blower 5 with the angle relative to horizontal direction less than 30 °.

Circuit board 41 is vertically arranged, preferably short side under, long side in side, but long side also may be implemented under it is practical Novel purpose.Short side is under, bottom and bottom sides that its most of element can be made most strong far from 1 electromagnetic interference of coil panel Edge region is conducive to protect component.For the product of electric cooker electric pressure cooking saucepan class, circuit board 41 is vertically arranged, can be abundant Using the depth of pot body, space is saved to greatest extent.For the utility model, circuit board 41 be erected in radiator 42 it On, and most preferred position is end of the radiator 42 far from 5 side of blower, in this way, the structure of a L-type is just constituted, Certainly, this is substantially L-shaped, as shown in Fig. 3.Here the side view that automatically controlled mainboard 4 is described with L-type, is in order to clear Positional relationship between easy description circuit board and radiator is not that limit automatically controlled mainboard 4 from the side must be a L Shape, actually this is also impossible, because the thickness of radiator 42 and circuit board 41 are different, is also set up on circuit board 41 There are various components.The both sides of L-type structure also allow for a degree of inclination, because under special circumstances, radiator It can be obliquely installed with circuit board, the L-type formed at this time would not be the L-type of a standard；In addition, if circuit board 41 is not close to The edge setting of radiator 42, for example leave left edge and be little by little arranged, entire automatically controlled mainboard 4 can also be made to seem not It is the L-type of a standard.But these set-up modes, it can substantially regard a L-type as, it is practical new to be possible to this Type purpose.The tangential gas flow produced by boasting from blower 5, other than largely flowing to radiator 42, a part of tangential gas flow passes through Gap of the radiator 42 between 2 outer wall of 5 end of blower and coil brace blows to other portions of automatically controlled mainboard 4 from bottom to top Point, although this subelement fever be not very acutely, due to foring new airflow channel so that heat dissipation is more uniform, Radiating efficiency is improved, all possible air duct is effectively utilized, so that the intracorporal air-flow of shell is sufficiently flowed, in automatically controlled mainboard Positive wind pressure is formd around 4, is filled with the space of side behind circuit board, and the hot air reflux for avoiding other heat dissipation original parts from generating is extremely The region of the circuit board.Certainly, the other positions or even circuit board 41 on 42 top of radiator also can be set in automatically controlled mainboard 4 Surface where component can not also face blower 5, although these not preferred arrangements are also than the arrangement of the prior art Mode will be got well, and the purpose in the saving space and cost of this patent may be implemented.But come from radiating efficiency and space utilization rate It says, can all be weakened compared to preferred embodiment, some arrangement forms, or even will increase the occupied shell space in the part. Certainly, so-called be vertically arranged not is absolute, it should be understood that it is substantially vertical, for example be tilted within 5 ° and just belong to permission model Within enclosing.As long as the space around coil brace can be made full use of, circuit board 41 can also be with small relative to vertical direction Be set to 42 top of radiator in 30 ° of angles, for example, coil brace 2 side lower part space it is abundant when, so that it may consider Circuit board 41 is inclined at 42 top of radiator, the side lower part of coil brace 2 is protruded into one end, and the other end is arranged as far as possible to be dissipated In the range of hot device, in this way, the height of circuit board occupancy can be further reduced, so that compact-sized.Meanwhile radiating airflow is also It is that can be blown over from the component surface on circuit board.

In heating module, can by coil brace 2 be used as main assembly parts, that is to say, that coil panel 1, automatically controlled mainboard 4, The components such as blower 5, temperature measurement component 6, wind path wall can be assembled using coil brace 2 as benchmark, and these components can To make full use of around coil brace 2, the space of side-lower and underface, make all parts dispersed originally, concentrate online Near coil support 2, be integrated into a very small size of master die group, each component can be found on coil brace 2 with All parts are directly plugged to coil brace 2 by itself corresponding mounting structure, when production.Therefore, the utility model Heating module installation it is very simple, position accuracy is very high between all parts, and repair and replacement associated components it is non- It is often convenient.In addition, compact-sized be also possible that mould group generalization degree is high, overall cost is low, a general portion can be used as Part or module, which are suitable for electric cooker, electric pressure cooking saucepan and electric cooker of various types or model etc., has circular shape The electric appliance of the induction coil heating of interior pot, designer is only with some additional functions of completion and the appearance of product, shell, face Plate design can develop new product, and the complete machine development cycle is obviously shortened, and cost is substantially reduced.

With reference to Fig. 1-2, the coil panel 1 in the utility model is in recessed container-like.For example, with reference to Fig. 1, this reality It applies in example, coil panel 1 is substantially in bowl-shape.In a preferred embodiment, the coil brace 2 is wrapped in outside the coil panel 1, institute The shape for stating coil brace 2 is matched with coil panel 1.It in this case, will shape between coil panel 1 and coil brace 2 The space of the base closed of coil 3 is accommodated at one, this design is formd using existing coil panel 1 and coil brace 2 Several air ducts for surrounding coil, the axial flow for being conducive to that blower 5 is guided to blow out upwards are prevented quickly through cocurrent depanning group The heat diffusion of coil panel 1 region unsmooth to heat dissipation.Certainly, coil brace 2 is also possible to the structure of non-close form, this When, coil brace 2 does not coat all areas of coil panel 1, but only retain the supporting support for being enough to support coil panel 1 and Magnetic stripe bracket etc. although alleviating weight and production cost, and is also able to achieve the main mesh of the utility model in this case , it is more preferable to the control of modular volume, but heat dissipation effect necessarily decreases, and also declines seriously to the control of air-flow.

With reference to Fig. 2, fan installing structure 25, assembling are set by center in the outer bottom of the coil brace 2 Structure 25 is mainly two blower fixed ears.

In order to which the wind for blowing out blower 5 is oriented to automatically controlled mainboard 4 and heat is discharged, the utility model is in coil brace 2 Side and bottom are provided with air duct wall construction.Certainly, in various embodiments, fan air channel wall construction also can be set in wind On machine.

Air duct wall construction includes fan air channel wall 22 and bracket wind path wall 23.The fan air channel wall 22 is used for the wind The lateral airflow that machine 5 generates is oriented to the direction of the radiator 42 and circuit board 41；Bracket wind path wall 23 passes through institute for guiding The air-flow for stating gap between the top of radiator 42 and 2 outer surface of coil brace blows to component on the circuit board 41, and from Mould group is discharged in 23 top of bracket wind path wall (circuit board).Theoretically, air duct wall construction be can individually include blower Wind path wall 22, it is this to design the goal of the invention that equally realize the utility model substantially.But due to being not located at electricity Wind path wall between 2 shell of road plate 41 and coil brace is passed through from gap between 42 top of radiator and 2 outer surface of coil brace Air-flow, the direction of circuit board can only be substantially blowed to, and blow to the air-flow of circuit board, as drawing without good air duct It leads and is dispersed to circuit board surrounding, will cause the raising of case temperature sometimes, radiating efficiency is affected.

Specifically, the fan air channel wall 22 of the present embodiment includes:

First wind path wall 201, both ends connect with the both ends far from automatically controlled mainboard 4 of fan installing structure 25 respectively, surround In 5 side of blower.Preferably, the first wind path wall 201 is arc-shaped.

Two the second wind path walls 202, the head end of two the second wind path walls 202 is respectively with fan installing structure 25 close to electricity Control the both ends connection of mainboard 4, each second wind path wall 202 is along being gradually distance from the second wind path wall of opposite side 202 and towards automatically controlled mainboard 4 Direction extend.Preferably, two the second wind path walls 202 are cut into fan shape to the side of automatically controlled mainboard 4 with 201 phase of the first wind path wall To extension.

Two five-duct walls 205 are corresponded with two the second wind path walls 202, and each five-duct wall 205 is from close The position of the head end of corresponding second wind path wall 202 starts, along moving closer to opposite side five-duct wall 205 and towards automatically controlled mainboard 4 direction extends.
