Fig. 2 is the structural schematic diagram for the health-promotion kettle that the utility model embodiment one provides.Fig. 3 is the utility model embodiment The structural schematic diagram of heating device in one health-promotion kettle provided.Fig. 4 be the utility model embodiment one provide health-promotion kettle in send out The structural schematic diagram of heat pipe.As shown in Figures 2 to 4, health-promotion kettle provided in this embodiment specifically includes kettle body 1 and is located at kettle body 1 Interior heating device 2, heating device 2 include being located at the heat transfer disk 21 of the bottom of kettle body 1 and being coiled in 21 bottom surface of heat transfer disk extremely Few two heat-generating pipes 22, all heat-generating pipes 22 surround close-shaped, each heat-generating pipe jointly in the circumferential direction of 21 bottom surface of heat transfer disk End it is adjacent with the end of another heat-generating pipe, and each adjacent two end is connected on the power supply line of identical polar.

Wherein, optionally, kettle body 1 is specifically as follows the kettle body of glass pot body or other transparent materials.Kettle body 1 in this way It is inside and outside transparent, so during cooking, 1 inside food materials of kettle body can be clearly seen through transparent kettle body 1 in user Boil state, the process so that control is boiled, and trusts safe drink.In addition, transparent glass pot body has preferable texture, The aesthetics for improving the anti-overflow health-promotion kettle, improves user experience.It is defended in addition, kettle body 1 can also meet food by other The material of raw safety is made, such as plastics of food-grade etc..

When specific implementation, kettle body 1 may be configured as single layer or bilayer, and have in kettle body 1 for holding health food materials Inner cavity, the top of inner cavity usually have opening, and all kinds of health food materials are put within kettle body 1, in addition, the top of kettle body 1 is logical Often be additionally provided with the structures such as pot lid 11, so as to closing inner chamber, improve heating efficiency, at the same avoid introduced contaminants fall into inner cavity it In.In addition, being also provided with the handle 12 for holding manipulation for user in the kettle body 1 of health-promotion kettle, and for carrying out work Make state control, or carry out heating temperature, the display control panel of the running parameter of heating time setting etc..

In order to heat to the health food materials held in inner cavity, heating device is additionally provided in the kettle body 1 of health-promotion kettle 2, heating device 2 has generally comprised heat transfer disk 21 and at least two heat-generating pipes 22.Wherein, heat transfer disk 21 is usually located at inner cavity Bottom position, and serve as the medium of heat produced by for transmitting heat-generating pipe 22.Heat transfer disk 21 may be provided at outside the bottom wall of inner cavity Side, or constitute a part of bottom wall of inner cavity.In addition, heat transfer disk 21 either be only located at the bottom wall of inner cavity, can also wrap up The bottom wall of inner cavity, and the side wall of inner cavity is extended upwardly to, to be eaten simultaneously from the bottom of inner cavity and side to the health in inner cavity Material is heated.Heat transfer disk 21 is generally metal material and is made, so as to faster heat-transfer rate.

When specific implementation, in the present embodiment, the bottom of kettle body 1 is generally also provided with for controlling adding for heating device The structures (not shown) such as temperature controller of hot temperature, temperature controller and heating device electrical connection, so as to according to liquid in kettle body 1 The heating power or on/off of the temperature control heating device 2 of body.

In order to realize the heating to health food materials, the heat-generating pipe in heating device is usually resistance-type heat-generating pipe.Heat-generating pipe Two ends be used to be connected to power supply, and the middle section region between the both ends of heat-generating pipe is heating position, can be generated big Calorimetric amount.Since two ends of heat-generating pipe are served only for being connected to power supply, end itself does not generate heat, but as fever The cold end of pipe exists.

In general, in the case where the parameters such as heating system, fever material are same or similar, the heating power one of heat-generating pipe As it is related with the size of heat-generating pipe.And caliber it is same or similar when, the length of heat-generating pipe is longer, and heating power is higher. Thus the heat transfer efficiency between the heating power and heat-generating pipe 22 and heat transfer disk 21 in order to improve heat-generating pipe 22, heat-generating pipe 22 are logical Often with there is longer length, and heat-generating pipe 22 is wound into curve or arcuate shape on the bottom surface of heat transfer disk 21, in this way can The longer heat-generating pipe 22 of length is set on 21 bottom surface of heat transfer disk of limited diameter, to guarantee that health-promotion kettle has enough heating Power and heating efficiency.

And the heat-generating pipe 22 for being used to generate heat has two or more, these heat-generating pipes 22 are coiled in heat transfer The bottom surface of disk 21, and all heat-generating pipes 22 surround one in the circumferential direction of 21 bottom surface of heat transfer disk in the shape of closure jointly.At this point, Since heat-generating pipe 22 is longer tubulose or linear structure, thus heat-generating pipe 22 obviously can not extend always in the same direction. In order to heat-generating pipe 22 be allowed to conduct heat by multiple bottom surfaces for being placed in heat transfer disk 21 jointly with the heat-generating pipe 22 of long length It is wound into curve or arcuate shape on the bottom surface of disk 21, and joins end to end between multiple heat-generating pipes 22, the end of different heat pipe It is disposed adjacent between portion and end, so that the shape of closure be collectively formed.This makes it possible at 21 bottom of heat transfer disk of limited diameter The longer heat-generating pipe 22 of several length is arranged on jointly on face, thus guarantee health-promotion kettle have enough heating powers and Heating efficiency.

Wherein, multiple heat-generating pipes 22 are close-shaped to be specifically as follows circle or ellipse when being surrounded by close-shaped jointly Circle etc..

In general, heat-generating pipe 22 is respectively positioned in same level.Because being usually relied between heat-generating pipe 22 and heat transfer disk 21 Heat exchange pattern carries out the transmitting of heat, and the distance between heat-generating pipe 22 and heat transfer disk 21 should keep close or equal everywhere, with Just it realizes and guarantees uniformly transferring for heat.

Simultaneously as the end of each heat-generating pipe can close on setting with one of end of other heat-generating pipes, in order to Short circuit phenomenon, the end of each heat-generating pipe and the end phase with the heat-generating pipe occur between the power supply line for avoiding end from being connected The end of adjacent another heat-generating pipe can connect the power supply line of identical polar.The power supply line connected by two neighboring end Polarity is identical, thus potential difference in this two power supply lines or current phase can be consistent, even if two different heat pipes Adjacent end portion power supply line is adjacent to one another or even contact, short circuit phenomenon will not occur between power supply line, to ensure that not It still is able to be worked normally when end is adjacent to one another with heat-generating pipe.It will not between heat-generating pipe 22 in this way in heating device 2 There are biggish notches, thus it is uneven also to cause to conduct heat on heat transfer disk 21 because of notch phenomena such as, to accomplish to feeding Health food materials in raw pot are evenly heated, and phenomena such as being sticking is avoided.

It is evenly heated effect in order to further increase, as an alternative embodiment, at least two heat-generating pipes 22 can To be separately positioned on the different zones of 21 bottom surface of heat transfer disk.Specifically, different heat pipe can be located at 21 bottom surface of heat transfer disk not Same position, such as the left area and the right area that are located at 21 bottom surface of heat transfer disk etc., such heat-generating pipe 22 is in heat transfer disk 21 Whole coverage area on bottom surface is larger, thus heat-generating pipe 22 is when heated, can be to multiple areas of entire 21 bottom surface of heat transfer disk Domain is heated, to effectively improve the uniformity of health-promotion kettle heating.

Wherein, different heat pipe can be located at not ipsilateral on 21 bottom surface of heat transfer disk.Multiple hairs in this way in heating device 2 The region occupied on 21 bottom surface of heat transfer disk of heat pipe 22 is not located at certain side of 21 bottom surface of heat transfer disk, but more uniformly The two sides for being distributed in 22 bottom surface of heat transfer disk or more side regions in, i.e. bottom surface scattering device of the heat-generating pipe 22 in heat transfer disk 21.With In the prior art, heat-generating pipe is located at the set-up mode of heat transfer disk bottom surface side regional area (such as all heat-generating pipes is only located at biography The left area of hot plate bottom surface or the right area for being only located at heat transfer disk bottom surface) it compares, multiple heat-generating pipes 22 in the present embodiment The mode not ipsilateral positioned at 21 bottom surface of heat transfer disk can heat more side different zones on 21 bottom surface of heat transfer disk, thus Improve the whole heating uniformity of heating device 2.

Specifically, heat-generating pipe 22 is located at the different zones of 21 bottom surface of heat transfer disk, it can be these regions and be located relative to pass The center of hot plate 21 it is not ipsilateral.Heat-generating pipes different in this way will not concentrated setting in certain side of heat transfer disk 21, but disperse It is arranged on entire heat transfer disk 21.

In order to form different heating effects, heat-generating pipe 22 can have different quantity and different arrangement modes.Make For a kind of optional arrangement mode, at least one heat-generating pipe is arc-shaped heat-generating pipe, and the circular arc of arc-shaped heat-generating pipe is convex to carry on the back Side from 21 center of heat transfer disk.At this point, arc-shaped heat-generating pipe is that circular arc is convex to outside, and circular arc both ends are towards heat transfer disk Center indent shape so that these heat-generating pipes can arrange around the geometric center of heat transfer disk 21, and common split As a closed shape.

Wherein, multiple heat-generating pipes 22 can be centrosymmetric relative to the geometric center of heat transfer disk 21 setting or phase Horizontal central line axisymmetricly shape setting for heat transfer disk 21.In this way health-promotion kettle realize heating when, 21 center of heat transfer disk Two sides are heated more uniformly, thus whole heating uniformity is preferable.

Specifically, due to health-promotion kettle generally access be 220V alternating current mains supply, thus 22 end of heat-generating pipe Power supply line can also be directly accessed alternating current.Wherein, the transmission of mains supply is usually in the form of three-phase electricity, in three-phase equilibrium When, the electric current of the zero curve (N) in mains supply is zero, and three of three-phase electricity have 220V voltage between phase line and zero curve, i.e., For firewire (L).At this point, it is optional, in the present embodiment, when each heat-generating pipe at least two heat-generating pipes is connect with power supply line When, it can be on the firewire L that each adjacent two end is both connected in power supply line, be also possible to each adjacent two end and be all connected with On zero curve N in power supply line.Since potential difference being not present between firewire and firewire or between zero curve and zero curve, because And it even if is in contact between one of end of some heat-generating pipe and adjacent end portion on another heat-generating pipe, also not Short circuit phenomenon can be generated.Can allow in this way has lesser interval between the end of different heat pipe, to allow heat-generating pipe can Biggish heat transfer disk range is covered as far as possible,

In addition, optional, at least two heat-generating pipes 22, the heating power of all heat-generating pipes can be identical；Alternatively, institute Having heat-generating pipe can also be identical size and shape；Again alternatively, the heating power and size shape of all heat-generating pipes With identical.At this point, each heat-generating pipe 22 has similar heat transfer rate or heat transfer efficiency between heat transfer disk 21, if will When heat-generating pipe 22 is configured according to the centrosymmetric mode relative to heat transfer disk 21, it is each that heat transfer disk 21 can be further increased Temperature uniformity between a region is better able to improve the heating uniformity of heating device 2.

In addition, in general, for the ease of carrying out the connection between 22 end of heat-generating pipe and power supply line, in multiple heat-generating pipes 22 In, there is interval between two adjacent ends.Power supply line can be relatively easy to be connected to the end of heat-generating pipe 22, cloth in this way Line is relatively easy to.

Optionally, there can be the heat-generating pipe 22 of different number in heating device 2, and in order to allow in multiple heat-generating pipes per adjacent Two ends are both connected on the power supply line of identical polar, and the quantity of heat-generating pipe 22 can be even number, heat-generating pipes 22 multiple in this way End to end, when enclosing close-shaped jointly, the quantity of the junction between 22 end of heat-generating pipe is equally even number, e.g. 2n (n is natural number), thus 2n junction can be connect with n firewire L and n zero curve N respectively, realize multiple fevers Each equal normal power-up fever of heat-generating pipe in pipe.

Wherein, in order to simplify the overall structure of heating device 2, the quantity of heat-generating pipe 22 can be 2,4 or 6 or Other quantity etc..

As one of optional embodiment, heating device 2 may include two heat-generating pipes, that is, heat-generating pipe 22a and heat-generating pipe 22b, two heat-generating pipes 22a and 22b are separately positioned on the two sides at the center of 21 bottom surface of heat transfer disk.Specifically, two A heat-generating pipe 22a and 22b can be sticked in the subjacent of heat transfer disk 21, and two heat-generating pipes 22a and 22b are located at heat transfer The geometric center of 21 bottom surface of disk it is not ipsilateral, be e.g. located at the left and right side of 21 geometric center of heat transfer disk；Meanwhile it sending out The end 221b of the end 221a and heat-generating pipe 22b of heat pipe 22a are adjacent, and connect with firewire L；The end of heat-generating pipe 22a The end 222b of 222a and heat-generating pipe 22b is adjacent, and connect with zero curve N.At this point, two heat-generating pipes 22a and 22b can be simultaneously Work, to heat simultaneously to the left and right side of heat transfer disk 21, and the left and right sides of heat transfer disk 21 has obtained heat-generating pipe After the heating of 22a or 22b, it will be able to allow heat more uniformly to pass to the health food materials held in health-promotion kettle, avoid supporting Material is eaten raw to occur being sticking phenomenon.

Wherein, two heat-generating pipes 22a and 22b in heating device 2 both can have identical form factor and fever Power, or two shapes and the different heat-generating pipe of heating power.And heating device 2 is with the phase of the specification of heat-generating pipe It is same or different, it may have different heating uniformities.

Optionally, two heat-generating pipe 22a and 22b can also form other different arrangement shapes on 21 bottom surface of heat transfer disk Shape.As long as heat-generating pipe 22a and 22b can collectively cover the large area on 21 bottom surface of heat transfer disk, and will not influence heat-generating pipe 22a And the energization and fever of 22b itself.

In general, since the shape of heat transfer disk 21 is usually discoid, thus in order to cover area as big as possible, In, be sticked two heat-generating pipes 22a and 22b in 21 bottom surface of heat transfer disk are arc-shaped, and two heat-generating pipes 22a and 22b can be with Mutually spliced by end, to surround a circular closed outline jointly.Specifically, the end 221a of heat-generating pipe 22a and The end 221b of heat-generating pipe 22b is adjacent, and the end 222b of the end 222a and heat-generating pipe 22b of heat-generating pipe 22a are adjacent, and heat-generating pipe Itself of 22a and heat-generating pipe 22b are convex to the direction far from 21 center of heat transfer disk, and two such heat-generating pipe 22a and 22b are semicircle Shape, and be combined into a closed full circle shape jointly, thus only by heat-generating pipe 22a and 22b can surround one it is closed Round or elliptical shape.

When two heat-generating pipes 22a and 22b are located at the not ipsilateral of the center of heat transfer disk 21, and it is combined into closed circle jointly When the shapes such as shape, on the one hand, the shape is close to the shape of heat transfer disk 21, thus heat-generating pipe 22a's and heat-generating pipe 22b is each The distance between position and the position of each side of heat transfer disk 21 size are closer to, such heat-generating pipe 22a, 22b and heat transfer disk 21 It is not ipsilateral between all have similar heat transfer efficiency, can be improved the heating uniformity of heat transfer disk 21；On the other hand, heat-generating pipe The profile that 22a and heat-generating pipe 22b are combined into not merely occupies a side region of heat transfer disk 21, and is across entire heat transfer disk 21 Two sides, thus heat-generating pipe 22a and heat-generating pipe 22b can cover biggish heat transfer disk area, equally heat transfer disk 21 can be allowed right Health food materials carry out more uniform heating.

It should be noted that the anti-overflow health-promotion kettle of the present embodiment not only can be used to boil tremella, soya-bean milk, Radix Astragali, Radix Angelicae Sinensis, The healths food materials such as ganoderma lucidum, Poria cocos can also be used to boil tea, such as black tea, dark green tea, green tea, Pu'er etc., can also be used to it is to boil water, Milk, beverage etc., the utility model is not construed as limiting this.

In the present embodiment, health-promotion kettle specifically includes kettle body and is located at the intracorporal heating device of pot, and heating device includes being located at The heat transfer disk of the bottom of kettle body and at least two heat-generating pipes for being coiled in heat transfer disk bottom surface, all heat-generating pipes are in heat transfer disk bottom surface Surround jointly close-shaped in circumferential direction, the end of each heat-generating pipe is adjacent with the end of another heat-generating pipe, and each adjacent two End is connected on the power supply line of identical polar.Between heat-generating pipe in this way in heating device there is no biggish notch or Every, it is thus possible to more complete region on heat transfer disk is covered, avoids conducting heat on heat transfer disk uneven, to accomplish in health-promotion kettle Health food materials be evenly heated, avoid phenomena such as being sticking.

Embodiment two

In addition, heat-generating pipe may be more than two quantity in heat generating device.Fig. 5 is the utility model embodiment The structural schematic diagram of heat-generating pipe in a kind of two health-promotion kettles provided.As shown in figure 5, in the present embodiment, health-promotion kettle equally includes There are a kettle body 1 and heat generating device 2, and the overall structure of health-promotion kettle is similar with the health-promotion kettle in previous embodiment one, and it is aforementioned Embodiment one the difference is that, include 4 heat-generating pipes in the heat generating device 2 in the present embodiment, i.e. heat-generating pipe 22m, fever Pipe 22n, heat-generating pipe 22j and heat-generating pipe 22k, and in 4 heat-generating pipes, end of the end of each heat-generating pipe with other heat-generating pipes It is adjacent, and 4 heat-generating pipes surround a closed shape jointly.

Specifically, 4 heat-generating pipes in heat generating device can be arc-shaped heat-generating pipe, thus the circular arc of 4 heat-generating pipes It can be convex to away from the side at 21 center of heat transfer disk.The end of such 4 heat-generating pipes is end to end, can piece together one jointly A round or elliptical closed shape.At this point, the close-shaped shape close to heat transfer disk 21 that 4 heat-generating pipes surround jointly Shape, thus between the position of each side of heat-generating pipe 22m, heat-generating pipe 22n, heat-generating pipe 22j and heat-generating pipe 22k and heat transfer disk 21 away from It is closer to from size, and heat-generating pipe 22m, heat-generating pipe 22n, heat-generating pipe 22j and heat-generating pipe 22k can collectively cover heat transfer disk 21 Large area on bottom surface, it is thus possible to which the uniformity coefficient for improving heat transfer makes the realization of heating device 2 be evenly heated effect, avoids Health food materials occur being sticking phenomenon.

Wherein, in order to power to 4 heat-generating pipes, the end of 4 heat-generating pipes is connected with power supply line.And these heat-generating pipes The power supply line polarity having the same that the power supply line that each end is connected is connected with adjacent end.Due to two neighboring The polarity for the power supply line that end is connected is identical, thus when being powered to heating device, two electricity that two neighboring end is connected Perhaps current phase can be also consistent when two power supply lines are adjacent to one another or contact for potential difference in the line of source, will not be sent out Raw short circuit phenomenon makes 4 heat-generating pipes also can be real in the case where end is adjacent to one another to ensure that the normal work of heat-generating pipe Existing normal power-up work.

Specifically, since health-promotion kettle would generally access the mains ac power supply of 220V, thus heating device can also be allowed logical Heating effect when entering AC power source, and being powered using resistance realizes the fever of heat-generating pipe.Due to having 4 hairs in heat generating device Heat pipe 22m, 22n, 22j and 22k, and 4 heat-generating pipes are end to end by end, so one shares the company of two neighboring heat-generating pipe It connects and locates there are four also tools.At this point it is possible to two of them heat-generating pipe junction is enabled to access zero curve N, and another two heat-generating pipe connects Place accesses firewire L, while accessing the heat-generating pipe junction of zero curve and the heat-generating pipe junction interleaved setting of access firewire. Specifically, in the present embodiment, junction and heat-generating pipe 22j and the heat-generating pipe of heat-generating pipe 22m and heat-generating pipe 22n can be The junction access zero curve N of 22k, and the junction of heat-generating pipe 22n and heat-generating pipe 22j and heat-generating pipe 22k and heat-generating pipe 22m Junction access firewire L, one end of each heat-generating pipe can be allowed connect with zero curve N in this way, and the other end with firewire L company It connects, and each adjacent two end is connected to the power supply line of identical polar, i.e., accesses zero curve N simultaneously or access firewire L simultaneously. The electric connection between each heating tube and power supply is completed in this way.

Since in each heat-generating pipe, the end of each adjacent two heat-generating pipe is all connected with the power supply line of identical polar, even if 4 The distance between two neighboring end is relatively close in heat-generating pipe, will not cause short circuit phenomenon, between the end of such 4 heat-generating pipes Can keep closer spacing, avoid between each heat-generating pipe there are biggish notch or it is other cannot be by heat-generating pipe heating part Divide direct-fired region, thus the situation that the heat transfer for also just reducing or eliminating heat transfer disk is uneven, to accomplish to health Health food materials in pot are evenly heated, and phenomena such as being sticking is avoided.

In addition, in 4 heat-generating pipes, each heat-generating pipe all can be identical shapes and sizes, make corresponding to each heat-generating pipe Region can have the heat transfer efficiency and heat transfer rate being closer to, to further increase the homogeneous heating of heating device Property.In addition, 4 heat-generating pipes can also be different shape sizes or different heating powers, it specifically can be according to health-promotion kettle Specific structure or concrete application need and be configured, details are not described herein again.

In the present embodiment, health-promotion kettle specifically includes kettle body and is located at the intracorporal heating device of pot, and heating device includes being located at The heat transfer disk of the bottom of kettle body and four heat-generating pipes for being coiled in heat transfer disk bottom surface, circumferential direction of all heat-generating pipes in heat transfer disk bottom surface On surround jointly close-shaped, the end of each heat-generating pipe is adjacent with the end of another heat-generating pipe, and each adjacent two end It is connected on the power supply line of identical polar.There is no biggish notch or interval between heat-generating pipe in this way in heating device, More complete region on heat transfer disk thus can be covered, avoids conducting heat on heat transfer disk uneven, to accomplish in health-promotion kettle Health food materials are evenly heated, and phenomena such as being sticking is avoided.
