Different heating gradients are formed, the slurry is heated up from the side wall of the metal container, and then concentrated back to the overall center of the metal container. However, the path of the slurry rolling up near the adjacent two carbon fiber heating bodies may be different due to different heating gradients, so that the tumbling paths of the slurry near the adjacent two carbon fiber heating bodies during the upwelling process are crossed, so that the slurry is tumbling. The fluidity is further improved, so that the heating effect on the slurry of soybean milk and porridge is better.

detailed description

In order to make the technical means, the creative features, the achievement of the object and the effect of the present invention easy to understand, the present invention will be further described below in conjunction with the specific drawings.

The main object of the present invention is to find out the technical difficulty, the carrier volume and the heat transfer efficiency of the existing carbon fiber heating body on the metal container by analyzing the heating method of the heating device of the existing kitchen electric heating appliance and the carbon fiber heating method. In a disadvantage, the invention provides a heating container for a kitchen electric heating appliance and a food processing machine provided with the heating container.

Referring to FIG. 1 and FIG. 2, the heating container of the kitchen electric heating appliance of the present embodiment includes a metal container 1 and a heating device 2, and the metal container 1 is loaded with the object to be heated, and the metal container 1 can be made of carbon steel, stainless steel, zinc alloy, The aluminum alloy, the pig iron, the stainless steel and the like are made of a material, and the heating device 2 includes a heat conductive insulating layer 21, which is a foundation on which the heating device 2 is disposed on the outer surface of the metal container 1, and functions as both heat conduction and insulation.

The thermal conductive insulating layer 21 may be formed of an enamel layer which is disposed on the outer surface of the metal container 1 by coating, and may be disposed by using multiple enamels when the enamel layer is disposed. The enamel layer is the basis of the entire heating device 2 disposed on the outer surface of the metal container 1. The reason for using the enamel layer is that the enamel and the metal container 1 have good bonding strength, and can avoid the metal container 1 and the enamel layer during the thermal shock. Peeling, and the enamel has a higher temperature resistance, can better adapt to the heating needs of the heating container, and at the same time, the enamel layer also serves as a requirement for insulation between the metal container 1 and the carbon fiber heating body 22.

For the enamel layer, the thickness can be between 0.01 mm and 0.7 mm for the sake of insulation and heat transfer efficiency. Preferably, the thickness of the enamel layer is 0.1 mm to 0.4 mm, which is matched with the setting of multiple enamels. In a manner, the enamel layer has good bonding strength with the outer surface of the metal container 1, and the peeling of the metal container 1 and the enamel layer during cold and thermal shock is avoided, and the temperature resistance of the enamel layer is preferably at least 300 °C.

The metal container 1 of the present invention may also be a composite metal container. For example, the metal container 1 includes a stainless steel container body. An iron coating layer is disposed on the outer surface of the stainless steel container body, and the enamel layer of the heating device 2 is disposed on the iron coating layer, thereby realizing The heating device 2 is mounted on a composite metal container. For the iron coating, it is possible to cover only a small portion of the stainless steel container body (for example, the bottom outer surface of the stainless steel container body to form a bottom structure), or to provide a large or all iron coating on the outer surface of the stainless steel container cup body. . In this way, on the one hand, the strength of the metal container 1 can be enhanced, and the heat transfer efficiency can be improved. On the other hand, the enamel layer of the heating device 2 and the iron coating layer are also better combined to prevent the enamel layer from being peeled off due to thermal shock. It can be understood that, in the case of using a composite metal container, in addition to the above-described manner of providing an iron coating on the outer surface of a metal container body, the metal container 1 of the present invention can also adopt a direct multi-layer composite (three or more layers). The composite metal container, the heating device 2 is disposed on the outer surface of the outermost layer of the most composite metal container, and can be selected according to actual needs, and will not be described here.

In addition, the present invention can also be provided with an outer metal container on the heating device 2 such that the heating device 2 is disposed between the metal container 1 and the outer metal container. Since the outer metal container is provided, the heating container of the kitchen electric heating device of the present invention can be It is not necessary to provide another outer casing structure outside the metal container 1, and the entire heating container forms a seamless structure. The metal container 1 and the outer metal container may be fixedly connected at the openings of the two, and the outer metal container may be a stainless steel container, an aluminum container or an iron container, and the metal container 1 and the metal container 1 and the heating device 2 are arranged, Any of the foregoing embodiments may be employed.

Of course, the thermal conductive insulating layer 21 can also be made of a thermally conductive insulating coating having a temperature resistance of more than 300 degrees Celsius, and the thermal conductive insulating coating layer can be a silicate coating layer, an oxide coating layer, a non-oxide coating layer, and a composite ceramic. There are many types of materials for the thermal conductive insulating coating layer which can be used for the coating layer, etc., and will not be described here. For the thermal conductive insulating coating layer, it can also be set by spraying, and the thickness can also be set between 0.01 mm and 0.7 mm. For the comprehensive consideration of insulation and heat transfer efficiency, it is preferably 0.15 mm to 0.5 mm. .

After the arrangement of the thermally conductive insulating layer 21 is completed, the carbon fiber heating body 22 is disposed on the thermally conductive insulating layer 21, and the carbon fiber heating body is provided because the thermal conductive insulating layer 21 has not dried the viscosity itself and the roughness of the surface of the thermally conductive insulating layer 21 itself. 22 may be disposed on the thermally conductive insulating layer 21 by friction between itself and the thermally conductive insulating layer 21. Of course, in order to make the arrangement of the carbon fiber heating body 22 on the heat conductive insulating layer 21 more convenient and reliable, the carbon fiber heating body 22 may be bonded on the heat conductive insulating layer 21, and in actual operation, the carbon fiber heating body 22 may be directly immersed. After the carbon fiber heating body 22 is impregnated, the carbon fiber heating body 22 is placed on the heat conductive insulating layer 21, and after the adhesive is dried or dried, the carbon fiber heating body 22 is bonded to the heat conductive insulating layer 21. When the carbon fiber heating body 22 is disposed on the heat conductive insulating layer 21, the carbon fiber heating body 21 may be disposed in a reciprocating manner with respect to a planar position of the metal container 1, such as the bottom wall of the metal container 1, for a curved position, for example The side wall of the metal container 1, the carbon fiber heating body 21 may be arranged in a reciprocating manner, or may be arranged in a circumferential manner along the side wall of the metal container 1, and of course, other regular or irregular arrangement may be employed. Specifically, it can be selected according to actual needs.

In order to facilitate the arrangement of the carbon fiber heating body 22, while increasing the heat transfer area of the carbon fiber heating body 22, and reducing the heat load, the carbon fiber heating body 22 preferably uses a flat carbon fiber heating body, and the carbon fiber heating body 22 has a thickness of 0.1 mm. Up to 1.5 mm, the width can be from 1 mm to 15 mm, so that the heat transfer load per unit area is more uniform, and under the same power conditions, the temperature at the local maximum temperature point of the inner surface of the metal container 1 is more The low temperature is favorable for heating the material in the metal container 1 and avoiding the bottom of the paste, and the like, and is more favorable for the reliability of the carbon fiber heating body 22 package and the difficulty of reducing the package.

After the carbon fiber heating body 22 is bonded to the heat conductive insulating layer 21, only the preliminary mounting of the entire heating device 2 is completed, and the carbon fiber heating body 22 also has a requirement for insulation, and at the same time, the carbon fiber heating body 22 is oxidized when heated. The carbon fiber addition body 22 is aged. Therefore, in the present invention, the carbon fiber heating body 22 also needs to be encapsulated by the insulating encapsulation layer 23 such that the carbon fiber heating body 22 is encapsulated between the thermally conductive insulating layer 21 and the insulating encapsulation layer 23. The insulating encapsulation layer 23 may be made of enamel, and the carbon fiber heating body 22 is encapsulated by enamel to form an enamel encapsulation layer; the enamel may be used to encapsulate the carbon fiber heating body 22 to form a glaze encapsulation layer, for example, using corundum powder as a glaze encapsulation layer. A glaze encapsulating layer may also be formed by adding titanium white powder, chromium oxide, zirconium oxide, iron oxide or the like to the corundum powder. For the enamel encapsulation layer and the glaze encapsulation layer, it can be formed by sintering in a heating furnace at a temperature of 300 ° C to 1000 ° C. In order to reduce the cost and simplify the process, an insulating coating may be applied on the outside of the carbon fiber heating body 22, and the insulating coating is dried to form an insulating coating encapsulating layer. For the insulating encapsulation layer 23, the thickness may be from 0.1 mm to 1 mm depending on various options.

In order to further improve the utilization of thermal efficiency, in the present invention, the heating device 2 further includes an infrared reflective layer 24 disposed outside the insulating encapsulation layer 23, and the thermal radiation will be reflected toward the side of the metal container 1 after reaching the infrared reflective layer 24. The infrared reflective layer 24 may be formed by coating an infrared reflective coating on the outside of the insulating encapsulation layer 23 to form an infrared reflective coating layer; or by directly covering the aluminum foil, infrared reflection may be realized by providing an aluminum foil layer.

Of course, the heating device 2 of the present invention can further provide a layer of insulating material (not shown) outside the infrared reflecting layer 24 to increase the utilization efficiency of the thermal energy to a greater extent. Then, for the heating device 2 of the present invention, only the setting is satisfied. When the enamel layer, the carbon fiber heating body 22 and the insulating encapsulation layer 23 are required, the thickness can be as thin as 0.3 mm. In order to improve the simplicity of the process and better meet the requirements of insulation, the heating device 2 is only provided with the above three. In the case of a layer structure, the thickness is also between 0.3 mm and 2 mm. When the heating device 2 is further provided with the infrared reflecting layer 24 and the insulating material layer, the thickness of the heating device 2 is not easily more than 5 mm in view of the overall lightness of the heating device 2. Thus, the heat device of the present invention is small in size and light in weight, and is disposed on the heating container of the kitchen electric heating appliance, thereby reducing the space occupation and weight of the kitchen electric heating appliance, and improving the portability of the kitchen electric heating appliance. The structure of the kitchen electric heating appliance is more favorable. When the thickness of the heating device 2 is less than 2 mm, the heating device 2 is integrated with the metal container 1 to further improve the lightness of the heating container.

It should be noted that, for the heating container of the kitchen electric heating appliance of the present invention, the heating device 2 may be disposed on the outer surface of the bottom of the metal container 1, or may be disposed on the outer surface of the side wall of the metal container 1, as in the present embodiment, The bottom outer surface and the outer side surface of the metal container 1 are disposed to perform stereo heating of the material in the metal container 1. Of course, it can be understood that, for the metal container 1, the shape of the metal container 1 is not limited to the present invention, and the bottom of the metal container 1 may be a non-planar structure, for example, a spherical bottom or the like, and the metal container 1 may also be used. Other irregular shapes are provided as long as the heating device 2 is disposed on the outer surface of the metal container 1.

For the heating device 2, when the heat conductive insulating layer 21 is provided on the outer surface of the metal container 1, the heat conductive insulating layer 21 can be disposed on the outer surface of the metal container 1 by a large-area coating as in the embodiment, and the carbon fiber heating body 22 and The encapsulating layer 23 is only disposed at a desired position, so that on the one hand, the coating process of the thermally conductive insulating layer 21 is relatively simple, and on the other hand, the overall insulating effect on the metal container 1 is ensured. Of course, for cost reasons, it is also possible to arrange the thermally conductive insulating layer 21 only on the outer surface of the metal container 1 where the carbon fiber heating body 22 is to be disposed in order to improve the economic efficiency of the heating container of the present invention, in the case where the insulation requirement is satisfied. In summary, any arrangement of the heating device 2 in any manner within the spirit of the invention should be within the scope of the claims of the invention.

In order to improve the convenience and reliability of the carbon fiber heating body 22 when it is arranged. Referring to FIG. 3 and FIG. 4 together with FIG. 5, in the present embodiment, first, two power supply terminals 3 are connected to both ends of the carbon fiber heating body 22, and the power supply terminal 3 realizes the carbon fiber heating body after the heating device 2 is installed. 22 is connected to the power source, and the power supply terminal 3 may be provided with a mounting hole for inserting the end portion of the carbon fiber heating body 22, or the power supply terminal 3 is provided with a clamping structure at one end of the carbon fiber heating body 22, and then one of the power supply terminals 3 is fixed on the heat conductive insulating layer 21, so that the power terminal 3 is pressed against one end of the carbon fiber heating body 22 on the heat conductive insulating layer 21, and the one end of the carbon fiber heating body 22 is positioned on the heat conductive insulating layer 21, thereby being carbon fiber. The subsequent arrangement of the heating body 22 lays the foundation (starting position positioning). It should be pointed out that, for the purpose of positioning, the fixing of the power terminal 3 is a temporary fixing, which does not require too high fixing strength, and can be directly bonded or directly utilized by the thermal conductive layer 21 (enamel or After the thermal conductive insulating coating is placed on the metal container 1, the fixing of the power supply terminal 3 is achieved because a certain viscosity is present because it has not been dried.

After the above arrangement is completed, in the present embodiment, as described above, since the thermally conductive insulating layer 21 has not dried the viscosity itself, and the roughness of the surface of the thermally conductive insulating layer 21 itself, the carbon fiber heating body 22 has been performed at one end. Positioning, through the friction between the carbon fiber heating body 22 and the heat conductive insulating layer 21, on the heat conductive insulating layer 21 The carbon fiber heating body 22 is disposed. Of course, the above manner of arranging the carbon fiber heating body 22 by friction is more suitable for circumferentially winding the carbon fiber heating body 22 on the outer surface of the side wall of the metal container 1, and after the carbon fiber heating body 22 is disposed, the other is further A power supply terminal 3 is fixed on the thermally conductive insulating layer 21 in the same manner as the previous power supply terminal 3, and the other power supply terminal 3 simultaneously presses the other end of the carbon fiber heating body 22 against the thermally conductive insulating layer 21. Then, the positioning of the other end of the carbon fiber heating body 22 on the heat conductive insulating layer 21 is completed, and after both ends of the carbon fiber heating body 22 are positioned, the operation of arranging the carbon fiber heating body 22 on the heat conductive insulating layer 21 is actually completed. . Then, it can be understood that in the above arrangement of the carbon fiber heating body 22, the two power supply terminals 3 actually function to position the carbon fiber heating body 22 in the carbon fiber heating body 22 arrangement (head and tail positioning or Positioning at both ends), the two power terminals 3 are also equivalent to positioning members for positioning the carbon fiber heating body 22. The positioning of the carbon fiber heating body 22 also makes the carbon fiber heating body 22 more convenient and reliable in arrangement. It can be understood that, in the present embodiment, the power terminal 3 can be directly connected to the end of the carbon fiber heating body 22, but the end portion of the carbon fiber heating body 22 is directly pressed on the heat conductive insulating layer 21. The structure can be set according to actual needs.

Referring to FIG. 6 and FIG. 7, in the embodiment, in order to further improve the convenience and reliability of the carbon fiber heating body 22 disposed on the heat conductive insulating layer 21, after the heat conductive insulating layer 21 is disposed on the metal container 1, the heat conduction can be performed. A plurality of positioning blocks 31 are fixed on the insulating layer 21, and the fixing of the plurality of positioning blocks 31 is also a temporary fixing manner, in the same manner as the above embodiment, in which the power terminal 3 is fixed on the heat conductive insulating layer 21. The requirement for the robustness is not high, and the fixing of the positioning block 31 can be achieved by simply bonding or by using the thermally conductive insulating layer 21 on the metal container 1 since there is a certain viscosity before drying.

Different from the foregoing embodiment, when the carbon fiber heating body 22 is arranged, a plurality of positioning blocks 31 are firstly arranged on the layout track of the carbon fiber heating body 22, where the layout trajectory of the carbon fiber heating body 22 can be actually In the present embodiment, when the carbon fiber heating body 22 is disposed on the outer surface of the side wall of the metal container 1 in a circumferential winding manner, different horizontal planes may be formed on the outer surface of the side wall of the metal container 1 (the metal container 1 is vertical) The straight positioning is taken as an example. A plurality of positioning blocks 31 are respectively disposed at equal circumferential intervals. When the carbon fiber heating body 22 is disposed on the heat conductive insulating layer 21, the positioning is performed by the positioning (hooking and clamping) of the plurality of positioning blocks 31. That is, for the interval of the plurality of positioning blocks 31 on the same horizontal surface, the spacing between different horizontal planes can be selected according to the accuracy requirement of the layout of the carbon fiber heating body 22. The positioning block 31 is arranged in such a manner that when the carbon fiber heating body 22 is arranged on the heat conductive insulating layer, the layout trajectory (line) is evidenced (continuous positioning in the intermediate position), avoiding errors in the arrangement of the carbon fiber heating body 22, and improving the carbon fiber. The convenience and reliability of the heating body 22 are arranged.

Therefore, with the present embodiment, even if it is necessary to arrange the carbon fiber heating body 22 in a vertically reciprocating manner on the heat conductive insulating layer 21 on the outer surface of the side wall of the metal container 1, it can be well realized. Referring to Fig. 8, in particular, when the carbon fiber heating body 22 is disposed on the planar outer surface of the metal container 1 (e.g., the bottom of the metal container 1), the present embodiment can be better realized, since the basic manner of arranging the carbon fiber heating body 22 is The same, no more description here.

Referring to FIG. 6 and FIG. 7, after the arrangement of the carbon fiber heating body 22 is completed, the carbon fiber heating body 22 is also required to be encapsulated by the insulating encapsulation layer 23. Before the carbon fiber heating body 22 is packaged, the thermal conductive insulating layer 21 may be firstly used. The positioning block 31 is removed to repack the carbon fiber heating body 22, and the positioning block 31 may be directly encapsulated between the insulating encapsulation layer 23 and the thermally conductive insulating layer 21 without removing the positioning block 31. It should be noted that the thickness of the insulating encapsulation layer 23 may not be too large. When the height (or thickness) of the positioning block 31 is large, the end portion of the positioning block 31 may be exposed outside the insulating encapsulation layer 23, this embodiment In the manner, the positioning block 31 is completely encapsulated in the insulating encapsulation layer 23. Regardless of whether or not the positioning block 31 is exposed to the insulating encapsulation layer 23, since the positioning block 31 is in direct contact with the carbon fiber heating body 22, the positioning block 31 is preferably made of an insulating material. The present embodiment can also be applied in combination with the foregoing embodiments to achieve continuous positioning of the carbon fiber heating body 22 at the initial and intermediate positions, and further improve the convenience and reliability of the arrangement of the carbon fiber heating body 22 on the thermally conductive insulating layer 21.

For the present embodiment, the infrared reflective layer 24 and the thermal insulation material layer (not shown) may be further disposed to increase the utilization rate of the thermal energy efficiency to a greater extent, and the arrangement is the same as the foregoing embodiment, for the thickness of the heating device 2 The manner of setting is also the same, and the foregoing embodiment has been described in detail, and will not be described here.

In the foregoing embodiment, whether the power terminal 3 is used as the positioning member or the positioning block 31 is directly disposed as the positioning member, the positioning member needs to be fixed on the heat conductive insulating layer 21 even if the fixing is a kind. Temporary fixing will still affect the arrangement efficiency of the subsequent carbon fiber heating body 22 to a certain extent. For industrial production, it seems that the efficiency is low and it is not conducive to improving the yield of product manufacturing.

Referring to FIG. 9, the tooling 4 is used in the embodiment to assist in the arrangement of the carbon fiber heating body 22 on the heat conductive insulating layer 21. The present embodiment still uses two power terminals 3 as positioning members, and FIG. 3 and FIG. The embodiment is different in that it is not necessary to fix the power supply terminal 3 to the thermally conductive insulating layer 21. In the specific operation, first, a power terminal 3 is pressed on the heat conductive insulating layer 21 through the positioning post 41 on the tooling 4, and one end of the carbon fiber heating body 22 (the power terminal 3 and one end of the carbon fiber heating body 22 are simultaneously pressed). The connection of one end of the carbon fiber heating body 22 on the thermally conductive insulating layer 21 is completed. The implementation of the arrangement of the carbon fiber heating body 22 on the thermally conductive insulating layer 21 is the same as that of the embodiment shown in FIGS. 1 and 2. After the arrangement of the carbon fiber heating body 22 is completed, another power supply terminal 3 is passed through the tooling 4. Another positioning post 41 is pressed against the thermally conductive insulating layer 21 and pressed against the other end of the carbon fiber heating body 22 to complete the positioning of the other end of the carbon fiber heating body 22 on the thermally conductive insulating layer 21. After the above operation is completed, one end of the two power connection terminals 3 pressed on the thermal conductive insulating layer 21 is encapsulated between the thermal conductive insulating layer 21 and the insulating encapsulation layer through an insulating encapsulation layer (not illustrated in FIG. 7). This is done simultaneously with the packaging of the carbon fiber heating body 22 itself, and finally the pressing force of the positioning posts 41 on the tooling 4 on the two power terminals 3 is withdrawn.

It should be noted that in the present embodiment, the tooling 4 is merely a simple example, and the structure of the tooling 4 capable of achieving the object of the present invention is many, and it is impossible to carry out the exhaustiveness in the description of the present invention, but the present invention does not. Any limitation is placed on the structure of the tooling 4, and all the structures of the tooling 4 which can achieve the object of the present invention are within the scope of the claimed invention. For example, in the tooling 4 of the present embodiment, in order to facilitate the self-installation, the tooling 4 is further provided with a fixing bracket 42 supported on the metal container 1.

Referring to FIG. 10, the present embodiment also employs the tooling 4 to assist in the arrangement of the carbon fiber heating body 22 on the thermally conductive insulating layer 21. This embodiment differs from the embodiment shown in FIGS. 6 and 7 in that no positioning block is required. 31, tooling 4, a plurality of positioning posts 41 are disposed. In a specific operation, the plurality of positioning posts 41 first protrude from the tooling 4 and abut the ends thereof against the heat conductive insulating layer 21, and the ends of the plurality of positioning posts 41 are sequentially Arranged on the layout track of the carbon fiber heating body 22, the carbon fiber heating body 22 is disposed on the heat conductive insulating layer 21 through the positioning of the plurality of positioning posts 41, and the operation manner is the same as that shown in FIG. 4 and FIG. No longer said. After the arrangement of the carbon fiber heating body 22 is completed, the plurality of positioning posts 41 on the tooling 4 are withdrawn. At this time, due to the frictional force between the carbon fiber heating body 22 and the heat conductive insulating layer 21, the positioning post 41 does not become after being withdrawn. The carbon fiber heating body 22 is dispersed, and the carbon fiber heating body 22 is packaged by an insulating encapsulating layer (not shown in Fig. 8). It should be noted that the manner in which the tooling 4 is used to assist the arrangement of the carbon fiber heating body 22 as shown in FIG. 9 and FIG. 10 can also be used in combination, and only a suitable tooling 4 is required, based on the foregoing disclosure of the present specification. Those skilled in the art will know how to operate, and will not be described here.

After the heating device 2 is disposed on the outer surface of the metal container 1, the carbon fiber heating body 22 needs to be connected to the power source, and the heating device 2 can heat the material in the metal container 1, and the insulating layer 23 is provided outside the carbon fiber heating body 22. When the carbon fiber heating body 22 is connected to the power source, the insulation effect of the insulating encapsulating layer 23 cannot be broken.

Referring to Fig. 11, in the present embodiment, the terminal 3 is provided at the end of the carbon fiber heating body 22. The number of the terminals 3 is determined by the number of the carbon fiber heating bodies 22 forming the circuit, and each of the carbon fiber heating bodies 22 forms a circuit. A pair of terminals should be formed at both ends thereof. In the present embodiment, only the arrangement of one of the terminals 3 is illustrated, and it is not indicated that only one terminal 3 is provided in the present invention.

In this embodiment, the terminal 3 includes a first end 31 for holding the end of the carbon fiber heating body 22, and the first end 31 is further provided with a receiving groove for accommodating the end of the carbon fiber heating body 22. The first end 31 can be insulated by heat conduction. The layer 21 has not been dried to have a certain viscosity to achieve the fixing on the thermally conductive insulating layer 21, and may also be bonded to the thermally conductive insulating layer 21 in the process of bonding the carbon fiber heating body 22 to the thermally conductive insulating layer 21, and The insulating encapsulating layer 23 is encapsulated between the thermally conductive insulating layer 21 and the insulating encapsulating layer 23 in the process of encapsulating the carbon fiber heating body 22. The terminal 3 also has a second end 32, and the second end 32 is disposed outside the insulating encapsulation layer 23, so that an external power source (not shown) and a carbon fiber heating body can be connected through the terminal 3 to connect an external power source wire (not shown). 22 connected. In the present embodiment, the first terminal 31 to the second end 32 of the terminal 3 are in a tower shape, and the insulating encapsulation layer 23 is encapsulated in the middle of the terminal 3, and the second end 32 is disposed outside the insulating encapsulation layer 23. The wires of the external power source may be directly soldered to the second end of the terminal block 3, or the fixing of the external power source wires may be achieved by providing a fixed structure of the external power supply wires on the second end 32.

Referring to FIG. 12, the difference between the embodiment and the embodiment shown in FIG. 11 is that the second end 32 of the terminal 3 is disposed at an angle with the first end 31. After the insulating encapsulation layer 23 is disposed outside the carbon fiber heating body 22, The second end 32 of the terminal 3 extends out of the insulating encapsulation layer 23 in an oblique manner, and the wire of the external power source can be provided with a plug-in fitting at the end thereof, thereby being inserted into the second end 32 of the terminal 3. This makes it easier to connect the wires of the external power supply to the terminal 3. It can be understood that, in the embodiment and the embodiment shown in FIG. 3, the first end 31 of the terminal 3 can be the first of the terminal 3 except that the end of the carbon fiber heating body 22 is pressed. The end 31 is provided as a structure capable of clamping the end of the carbon fiber heating body 22, thereby realizing the end of the carbon fiber heating body 22 The portion is clamped in such a manner that the first end 31 of the terminal 3 is more rigidly connected to the end of the carbon fiber heating body 22, and the first end 31 is more conveniently packaged.

Referring to Fig. 13, the manner in which the end of the carbon fiber heating body 22 of the present embodiment is connected to an external power source is more complicated than the foregoing two embodiments, but the connection mode is more stable. In the embodiment, a wiring assembly is disposed at an end of the carbon fiber heating body 22. The wiring assembly includes a bracket 41a fixed to an outer surface of the metal container 1. The bracket 41a may be welded to the metal container 1 before the outer surface of the metal container 1 is provided with a heat conductive insulating layer 21. The outer surface is then provided with a thermally conductive insulating layer 21 on the outer surface of the metal container 1. The thermally conductive insulating layer 21 also serves to further fix the bracket 41a. Then, an insulating pressing member 42a is provided on the bracket 41a, and the insulating pressing member is provided. The 42a can be made of a ceramic material. In the present embodiment, the end portion of the bracket 41a is further provided with a retaining portion for the insulating presser 42a. The function of the insulating pressing member 42a is to press the terminal 3, and the terminal 3 is pressed against the end of the carbon fiber heating body 22. The terminal 3 is further connected to the wire of the external power source to realize the connection between the carbon fiber heating body 22 and the external power source. . In the present embodiment, a preferred embodiment is adopted in which a threaded hole is provided in the insulating pressing member 42a, and a screw 43a is provided in the threaded hole, and the screw 43a is screwed toward the side of the terminal 3, so that the insulation is tightly pressed. The member 42a is pressed against the terminal 3, and the end of the screw 43a is also in contact with the terminal 3. The screw 43a can be made of a metal material. Then, the wire of the external power source can be directly connected to the end of the screw 43a to realize the terminal. The connection of 3, of course, can also press the wire of the external power source at the contact position of the screw 43a and the terminal 3. According to the spirit of the present invention, the external power source is connected to the carbon fiber heating body 22 by means of the terminal 3 in a variety of ways. In the present invention, it will not be described one by one.

It can be understood that the carbon fiber heating body 22 and the external power source can also be connected with the temperature controller and/or the fuse body to prevent the carbon fiber heating body 22 from being burnt, overheated or the bottom of the paste is dangerous. For the carbon fiber heating body 22 Play a protective role.

Referring to FIG. 14, in the embodiment, the thickness of the heat conductive insulating layer 21 is not more than 1 mm, and the carbon fiber heating body 22 is arranged to be wound along the circumferential direction of the side wall of the metal container 1, and the carbon fiber heating body 22 is in the metal container. 1 side wall is wound 3 times, and a certain gap d is set between two adjacent carbon fiber heating bodies 22 (the size of the gap d and the width of the carbon fiber heating body are merely exemplified in the drawings, not the proportion thereof. Description) Of course, in order to facilitate the winding of the carbon fiber heating body 22 on the side wall of the metal container 1, the carbon fiber heating body 22 is preferably flat and has a thickness of 0.1 mm to 1.5 mm. How the carbon fiber heating body 22 is wound around the side wall of the metal container 1 can be processed by referring to the above embodiments.

In order to increase the heating effect of the carbon fiber heating body 22 on the slurry in the metal container during operation, the arrangement height of the carbon fiber heating body 22 in the vertical direction of the side wall of the metal container 1 is required, and the carbon fiber heating body 22 is on the side of the metal container 1. The height H of the vertical direction of the wall should be between 20 mm and 80 mm. This arrangement is to ensure that a sufficient vertical heat source is generated at the side wall of the metal container 1 by the carbon fiber heating body 22 during operation, and the carbon fiber heating is performed. The extremely thin thermal conductive insulating layer 21 between the body and the side wall of the metal container, the carbon fiber heating body 22 is directly heated to directly the metal container 1, and the heating effect of the metal container 1 when the side wall is heated and transferred to the slurry in the metal container 1 is violent and direct .

Then, as shown in Fig. 14, after the slurry in the metal container 1 is heated from the side wall of the metal container 1, the heat source generated by the carbon fiber heating body 22 has a sufficient vertical height and violent force, so that the slurry in the metal container 1 is sharp Along The side wall of the metal container 1 is tumbling upward, reaching the highest point (above the stationary liquid level) near the side wall 1 of the metal container, and then concentrated back to the central area of the metal container 1. In this way, the slurry in the metal container 1 is not only heated more uniformly during the heating process, so that the fluidity of the slurry is greatly improved. When the metal container 1 heats the slurry such as soybean milk or porridge, the slurry flows from the side wall of the metal container 1 to the center. The flow characteristics of the regional tumbling heating can not only effectively avoid local overheating, but also increase the heating speed of the slurry of soy milk and porridge, which is beneficial to the rapid production of food. Especially in the production of soybean milk, the flow characteristics of the slurry from the side wall of the metal container 1 to the central region can also eliminate the foam to a certain extent, and the lower thermal inertia of the carbon fiber heating body 22, so that the metal container 1 is made. When the soybean milk is used, the overflow prevention space can be greatly reduced, so that the volume of the metal container 1 itself can be greatly reduced when the same capacity of soybean milk is produced, which is more conducive to the overall design.

In addition, in the present embodiment, the arrangement height H of the carbon fiber heating body 22 in the vertical direction of the side wall of the metal container 1 means that when the metal container 1 is placed vertically, the lowermost end of the side wall 1 of the metal container The lowest point of the carbon fiber heating body 22 is one turn, and the vertical height between the highest point of the carbon fiber heating body 22 at the uppermost end of the side wall 1 of the metal container. Then, in the present embodiment, since there is a gap between the adjacent two carbon fiber heating bodies 22, and the side wall of the metal container 1 has a vertical structure, the total width of the plurality of carbon fiber heating bodies 22 is smaller than that defined in the present invention. The height H is arranged, but when the side wall of the metal container 1 has a tapered section (for example, the lowermost end of the side wall of the metal container 1 is a tapered section which is upper and lower), the spacing between adjacent carbon fiber heating bodies 22 is set. The smaller, total width of the multi-turn carbon fiber heating body 22 can be greater than the arrangement height H as defined in the present invention.

Since the technical effect brought about by the main improvement of the present embodiment is based on the height H, the side wall of the metal container 1 can be either vertical as long as the metal container 1 of any shape satisfies the setting of the carbon fiber heating body 22 for the height H. Straight, conical, or other rules (e.g., curved faces) or irregular shapes, and various configurations are intended to be within the scope of the claimed invention. The carbon fiber heating body 22 may be in the form of a single flat carbon fiber heating body 22 in addition to the multi-turn winding form of the present embodiment, for example, a flat carbon fiber heating body 22 having a width of 30 mm is wound around the metal container. When the side wall of the metal container 1 has a vertical structure, the height H is the width of the carbon fiber heating body 22, and if the side wall of the metal container 1 in which the carbon fiber heating body 22 is provided is tapered, the height H The width of the carbon fiber heating body 22 is smaller than that of the carbon fiber heating body 22, as long as it satisfies the height H required by the present invention. The arrangement of the carbon fiber heating body 22 in the vertical direction of the metal container 1 is more preferably 30 mm to 60 mm because of the effect improvement and the overall height limitation of the metal container 1.

Of course, in the present embodiment, there is a further technical effect that the carbon fiber heating body 22 is wound on the side wall of the metal container 1 in a plurality of turns in the circumferential direction of the outer surface of the side wall of the metal container 1, because the carbon fiber heating body 22 is When the side wall of the metal container 1 is wound in a plurality of turns, the carbon fiber heating body 22 of each turn forms an independent heat source center, and the adjacent two carbon fiber heating bodies 22 heat the slurry in the metal container 1. Different heating gradients are formed, the slurry is heated to roll upward from the side wall of the metal container 1, and then concentrated back to the overall center of the metal container 1 as a whole. However, the path of the slurry rolling up near the adjacent two carbon fiber heating bodies 22 may be different due to different heating gradients, so that the tumbling paths of the slurry near the adjacent two carbon fiber heating bodies during the upwelling process are crossed, so that the slurry is tumbled. The fluidity is further improved, so that the heating effect on the slurry of soybean milk and porridge is better.

Based on the improvement of the heating gradient effect, the number of turns of the carbon fiber heating body 22 circumferentially wound on the side wall of the metal container 1 should be at least 3 turns, preferably 4 to 10 turns, correspondingly, carbon fiber The width of the heating body 22 is preferably from 5 mm to 15 mm, and the width of the carbon fiber heating body 22 is small, so that the carbon fiber heating body 22 is inconvenient in winding, and the width of the carbon fiber heating body 22 is large, so that the carbon fiber heating body 22 is made. The resistivity is low (the resistance value per unit length is low), and in the case of the same length, the total resistance of the carbon fiber heating body 22 is low, and the heating power control has certain difficulty. In addition, in order to avoid the temperature difference between the adjacent two carbon fiber heating bodies 22, the gap d between the adjacent two carbon fiber heating bodies 22 is preferably not more than 5 mm, and the adjacent two carbon fibers are adjacent. The heating bodies 22 may also be disposed in a gapless manner, and then the outer surface of the carbon fiber heating body 22 itself needs to be insulated or provided with other insulating structures therebetween, and the carbon fiber heating body is not subjected to insulation treatment, nor In the case of providing other insulating structures, it is preferable to maintain a gap of 2 mm to 3 mm between the adjacent two carbon fiber heating bodies 22, which not only does not cause a temperature difference problem, but also facilitates the need for gradient heating.

It can be understood that the carbon fiber heating body 22 can be disposed on the outer surface of the side wall of the metal container 1 in a continuous winding manner, and terminals (not shown) are disposed at the two ends of the carbon fiber heating body 22 for accessing the external power source, and more The root carbon fiber heating body 22 is separately wound and separately connected to an external power source, and can be selected according to requirements.

In addition, in addition to meeting the numerical requirements of the height H of the carbon fiber heating body 22 disposed on the side wall of the metal container 1, in order to further satisfy the heating effect requirement, the arrangement height H of the carbon fiber heating body 22 disposed in the vertical direction of the side wall of the metal container 1 cannot be lower than that of the metal. 20% of the height of the container 1 in the vertical direction. At the same time, in order to avoid making a large foamy material such as soybean milk, the arrangement of the carbon fiber heating body 22 having an excessively large height increases the height of the metal container 1 (the height of the arrangement of the carbon fiber heating body 1 cannot be high) In the static slurry level, the overflow prevention space of the upper portion of the metal container 1 is affected, and the height of the carbon fiber heating body 22 in the vertical direction of the side wall of the technical container 1 cannot be greater than 50% of the height of the vertical direction of the metal container.

In the embodiment, the bottom of the metal container 1 is also provided with a carbon fiber heating device, and the heating device comprises a heat conductive insulating layer disposed on the outer surface of the bottom of the metal container 1. The heat conductive insulating layer and the side wall of the metal container 1 are also made of an enamel layer or a thermal conductive insulating coating. The arrangement requirements of the layer, the enamel layer and the thermally conductive insulating coating layer are also the same, and then a carbon fiber heating body is disposed on the thermally conductive insulating layer, and the carbon fiber heating body is encapsulated between the thermally conductive insulating layer and the insulating encapsulating layer through the insulating encapsulation layer.

Since the carbon fiber heating body is simultaneously provided as a heating means at the bottom of the metal container 1, the slurry in the metal container 1 is caused to surge upward in the central portion of the metal container 1, the upwardly surging slurry and the aforementioned heating due to the side wall of the metal container 1 The slurry that has returned to the central area will have an impact convergence, which can further enhance the sufficiency of the slurry heating, and further improve the heating uniformity and speed of the soy milk, porridge and other slurry. The bottom shape of the metal container 1 is also not limited in the present invention, and may be a planar structure in the present embodiment, or a non-planar structure such as a spherical bottom or other irregularly shaped bottom.

It is not easy to paste the pot when heating the material. For the material with overflow risk such as soy milk, it is obvious that the anti-overflow control is simpler and more convenient.
