[0052] The technical solutions in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0053] It should be noted that if the embodiments of the utility model involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement condition, etc. between the components in a certain posture, and if the certain posture changes, the directional indications also change accordingly.

[0054] In addition, if the description of "first", "second" and the like is involved in the embodiments of the utility model, the description of "first", "second" and the like is only for the purpose of description, and cannot be understood as indicating or implying the relative importance of the indicated technical features or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first", "second" can be explicitly or implicitly included at least one of the features. In addition, if "and / or" or "and / or" appears throughout the text, it means that the three parallel schemes are included, for example, "A and / or B" includes A scheme, or B scheme, or A and B scheme. In addition, the technical solutions of each embodiment can be combined with each other, but it must be based on the realization of the ordinary skilled in the art, when the combination of technical solutions appears contradictory or unachievable, it should be considered that the combination of technical solutions does not exist, and is not within the protection scope required by the utility model.

[0055] In order to better adapt to the diameter of the pot, the electric heating device in the prior art usually sets the heating wire in the electric heating device in a plurality of annular heating zones which are basically concentrically distributed; when the diameter of the pot is small, the user can select the inner ring area heating wire to heat; when the diameter of the pot is large, the user can select the inner ring and the outer ring area heating wire to heat together; however, when the heating wire is only set in the inner and outer distribution state, the use effect is poor: since the inner and outer rings are almost in communication, the inner ring heat is easy to transfer to the outer ring, resulting in that the inner ring heat cannot be concentrated in the inner ring area, and the pot heating speed is slow; therefore, a feasible method is to increase a separation ring between the two heating annular areas to prevent most of the heat from flowing between the two annular areas; however, for the electronic temperature control furnace disc, the temperature probe for temperature control is generally arranged at the center position of the furnace disc, and the separation ring will cause the temperature probe to be unable to accurately detect the temperature of the outer ring area, resulting in inaccurate temperature control.

[0056] In order to solve the above technical problems, as shown in Figures 1 to 3 The utility model discloses an electric heating device 100, including installation main part 1, temperature measuring device 3 and at least two electric heating parts 2. The installation main part 1 includes heat insulation seat 11, the heat insulation seat 11 includes seat body 111 and blocking part 112, the seat body 111 has the first side and the second side who are opposite in its thickness direction, the blocking part 112 is located at the first side of the seat body 111, and extends along the circumference of the installation main part 1, to form first area 1111 and second area 1112 with the first side of the seat body 111 is separated, at least two electric heating parts 2 are divided and arranged in the first area 1111 and the second area 1112, the temperature measuring device 3 is arranged on the main body 4 on the area that communicates with the first area 1111 and the second area 1112.

[0057] As shown in Figure 4As shown, the technical scheme of the utility model provides space basis for the separate arrangement of the electric heating part 2 by arranging the barrier part 112 on the first side of the seat body 111, so that the electric heating part 2 can be located in different areas respectively, and the first area 1111 and the second area 1112 can be heated respectively according to different requirements or scenes, so that more flexible temperature control and heat distribution are realized. The temperature measuring device 3 is arranged in the area of the seat body 111 that communicates with the first area 1111 and the second area 1112, so that the heating conditions of the first area 1111 and the second area 1112 can be detected simultaneously or individually, accurate data feedback is provided for temperature control, and the working state of the electric heating part 2 can be adjusted better. Since the temperature measuring device 3 can measure the temperature of the first area 1111 and the second area 1112, the change of the feedback temperature is beneficial, and the electric heating part 2 in the corresponding area is adjusted, so that the temperature is always in a suitable range, and the precision of temperature control of the electric heating device 100 is improved.

[0058] It can be understood that the shape of the first side of the seat body 111, which is separated to form the first area 1111 and the second area 1112, can be circular, rectangular, polygonal and the like. Specifically, the circular shape can make the two areas uniformly distributed in the circumferential direction, and is suitable for some scenes that require local heating around the center, such as some circular heating equipment. The rectangle is relatively regular, which is convenient for layout and installation in a planar space, such as some flat plate type electric heating devices 100. The polygonal shape can be selected according to specific design requirements and space shape, such as triangle, pentagon and the like, so as to adapt to the installation space of special shape or realize a specific heating effect.

[0059] It can be understood that the seat body 111 and the barrier part 112 can be separately arranged, for example, by the following way: a detachable connection structure such as buckle connection, screw connection and the like is adopted to splice and assemble the barrier part 112 and the seat body 111, so that when the barrier part 112 needs to be replaced or repaired, the barrier part 112 can be conveniently disassembled and installed, and the maintainability and replaceability of the device are improved. It can also be integrally arranged, for example, by injection molding process and the like, so as to directly manufacture the seat body 111 and the barrier part 112 into an integral part. This integrated arrangement can increase the stability and sealing property of the structure, reduce the gap or looseness problem that may occur due to the separate connection, and also simplify the production process and installation process, and improve the production efficiency.

[0060] It can be understood that the temperature measuring device 3 can be arranged above the blocking part 112 to communicate with the first area 1111 and the second area 1112. However, it will occupy the height of the blocking part 112, reducing the heat insulation effect of the blocking part 112. Therefore, in an embodiment, the blocking part 112 is provided with a communication passage 1113 communicating the first area 1111 and the second area 1112; the temperature measuring device 3 is arranged in the communication passage 1113. In this way, by arranging the temperature measuring device 3 in the communication passage 1113, the temperature measuring device 3 can detect the temperature of the first area 1111 and the second area 1112. While ensuring accurate temperature detection, the heat insulation effect of the blocking part 112 is ensured.

[0061] It can be understood that the communication passage 1113 can be a perforation arranged on the blocking part 112, which communicates the first area 1111 and the second area 1112, so that the temperature measuring device 3 is installed in the perforation, which can simultaneously measure the temperature of the electric heating part 2 in the first area 1111 and the second area 1112. In addition, in an embodiment, the blocking part 112 is formed with at least one discontinuous port 1114, which forms the communication passage 1113. In this way, by forming the discontinuous port 1114 as the communication passage 1113 in the blocking part 112, the temperature measuring device 3 can detect the temperature of the electric heating part 2 in the first area 1111 and the second area 1112. In addition, the discontinuous port 1114 is more convenient and faster to set than the perforation, which is also conducive to the installation of the temperature measuring device 3. And the size of the discontinuous port 1114 can be accurately controlled to adapt to the temperature measuring device 3 to achieve the best heat insulation and temperature measurement effect.

[0062] As shown in FIG. 1, Figure 10 In an embodiment, the temperature measuring device 3 includes a mounting part 31 and at least one temperature sensor 32 arranged on the mounting part 31. In this way, the temperature sensor 32 can be fixed on the area communicating the first area 1111 and the second area 1112 by the mounting part 31, and the temperature of the first area 1111 and the second area 1112 can be detected separately or simultaneously. The temperature sensor 32 can be a semiconductor temperature measuring chip, a thermistor array, an optical fiber temperature measuring sensor, etc. Specifically, the semiconductor temperature measuring chip has the advantages of fast response speed, small size and low cost, and can sensitively perceive temperature changes. The thermistor array is composed of multiple thermistors, which can realize multi-point temperature measurement and accurately reflect the temperature difference at different positions. The optical fiber temperature measuring sensor measures temperature by using the temperature-sensitive characteristics of optical fiber, and has anti-electromagnetic interference.

[0063] It should be noted here that due to the difference in position and shape of the electric heating part 2 arranged in the first area 1111 and the electric heating part 2 arranged in the second area 1112, the thermal resistance (thermal resistance refers to the resistance of materials or objects to heat flow. It reflects the ability of objects to resist heat flow during heat transfer.) of heat transfer to the temperature sensor 32 is different, so when the electric heating part 2 in the first area 1111 works alone, the temperature sensor 32 is provided with a first temperature threshold value for the first area 1111; when the electric heating part 2 in the second area 1112 works alone, the temperature sensor 32 is provided with a second temperature threshold value for the second area 1112; when the electric heating part 2 in the first area 1111 and the second area 1112 works simultaneously, the temperature sensor 32 is provided with a third temperature threshold value for the first area 1111 and the second area 1112. By setting different detection temperature threshold values, the accuracy and sensitivity of temperature detection can be further improved, which is beneficial to the precise temperature control of the electric heating device 100.

[0064] In order to further improve the accuracy of temperature measurement of the first area 1111 and the second area 1112. In an embodiment, the temperature sensor 32 is provided with two, which are correspondingly arranged at the two side ends of the mounting part 31 adjacent to the first area 1111 and the second area 1112. In this way, the temperature information of the first area 1111 and the second area 1112 can be directly obtained respectively. The two temperature sensors 32 are respectively located at the two side ends of the mounting part 31 adjacent to the first area 1111 and the second area 1112, which can reduce the temperature measurement error caused by the deviation of measurement position or other factors, so as to more accurately reflect the actual temperature condition of the first area 1111 and the second area 1112. Through this double-side end setting mode, the accuracy and reliability of temperature measurement of the first area 1111 and the second area 1112 can be effectively improved.

[0065] In order to reduce the interference between the two temperature sensors 32, in an embodiment, the temperature measuring device 3 further comprises a partitioning portion, which is arranged on the mounting portion 31 and between the two temperature sensors 32. In this way, the partitioning portion plays a role of isolation, so that each temperature sensor 32 can independently measure the temperature of the corresponding area, thereby improving the accuracy and reliability of temperature measurement. The interference between the two temperature sensors 32 can be effectively reduced, and the measurement result of one temperature sensor 32 can be prevented from being affected by the other temperature sensor 32, so as to ensure that each sensor can accurately reflect the temperature condition of the position thereof.

[0066] In an embodiment, the mounting portion 31 comprises an insulating terminal seat 311, which is arranged through the seat body 111. The insulating terminal seat 311 is arranged on the portion of the first side of the seat body 111, and is used for mounting at least one temperature sensor 32. The insulating terminal seat 311 is provided with a wire outlet terminal 312 extending to the first side and the second side of the seat body 111. The wire outlet terminal 312 arranged on the portion of the first side of the seat body 111 is electrically connected with the electric heating portion 2. In this way, by arranging the insulating terminal seat 311 through the seat body 111, the temperature sensor 32 can be independently mounted with the seat body 111 and the electric heating portion 2, and the insulation performance is good, so as to effectively reduce the mutual interference of current and other safety problems such as electric leakage. In addition, the insulating terminal seat 311 arranged on the portion of the first side of the seat body 111 is used for mounting the temperature sensor 32, so as to facilitate the arrangement and fixation of the temperature sensor 32, and the temperature sensor 32 can accurately sense the temperature of the corresponding area. By arranging the wire outlet terminal 312 extending to the two sides of the seat body 111 on the insulating terminal seat 311, and arranging the wire outlet terminal 312 on the portion of the first side of the seat body 111 to be electrically connected with the electric heating portion 2, the transmission and connection of current are facilitated, so that the electric heating portion 2 can normally work, and the arrangement and maintenance of the wire are also facilitated.

[0067] In an embodiment, the mounting body 1 further comprises a housing 12, which is provided with an open mounting cavity. The heat insulation seat 11 is arranged on the bottom of the mounting cavity corresponding to the opening. The insulating terminal seat 311 is integrally arranged with the housing 12. In this way, by integrally arranging the insulating terminal seat 311 with the housing 12, the connection tightness and electrical insulation between the two are ensured, and the problems such as poor contact or electric leakage are reduced.

[0068] As Figure 5 and Figure 6As shown, in an embodiment, the circumferential edge of the first side of the seat body 111 is provided with a first support wall 13; in the direction away from the first side of the seat body 111, the height of the first support wall 13 is greater than the height of the blocking part 112. In this way, the first support wall 13 can be used to support the panel 41, so that the panel 41 can maintain a stable position and posture, reduce shaking or deformation due to its own weight or external factors, and improve the overall stability of the system. Moreover, in the direction away from the first side of the seat body 111, the height of the first support wall 13 is greater than the height of the blocking part 112, which can avoid the blocking part 112 lifting the middle of the panel 41, so that the panel 41 cannot be stably supported on the first support wall 13.

[0069] Further, in an embodiment, the height difference between the first support wall 13 and the blocking part 112 is a, and 0≤a≤3mm. In this way, by setting a within this range, the first support part can provide support while reducing interference with the normal function of the blocking part 112 due to the first support wall 13 being too high. For example, if the height difference is too large, the first support wall 13 will protrude too much, affecting the separation effect of the blocking part 112 on the first area 1111 and the second area 1112, and causing the temperature measurement accuracy to deviate.

[0070] In order to further improve the support of the panel 41, in an embodiment, the middle of the first side of the seat body 111 is provided with a second support wall 14; in the direction away from the first side of the seat body 111, the height of the second support wall 14 is comparable to the height of the first support wall 13. In this way, by setting the second support wall 14 and the first support wall 13 at the same height, the middle of the panel 41 can be supported, thereby increasing the support points and improving the support performance of the panel 41, ensuring the stability of the panel 41 in operation. Moreover, the weight of the panel 41 can be more evenly distributed, reducing the problem of bending or deformation of the panel 41 due to local stress. It can be understood that "the height of the second support wall 14 is comparable to the height of the first support wall 13" means that the first support wall 13 and the second support wall 14 can support the panel 41 on the same plane.

[0071] In an embodiment, the seat body 111 is provided with a through hole 1115 corresponding to the inner side of the second support wall 14, which communicates the first side and the second side of the seat body 111. In this way, a magnetic stripe or other sensor can be arranged at the through hole 1115. Specifically, the magnetic stripe can guide the strength of the magnetic field to achieve a specific effect. Other sensors can be used to monitor relevant physical quantities or environmental parameters, etc., to improve overall performance.

[0073] As Figures 7 to 9 As shown in the technical scheme of above-mentioned utility model, to guarantee the heating performance of the electric heating device 100, the electric heating device 100 is arranged close to the heating area 411 of the panel 41, to make the two electric heating parts 2 close to the heating area 411, when the cooking utensils 200 needs to switch to mixed heating mode, to carry out mixed heating to the heating area 411 on the panel 41, the control device controls the first coil assembly 51 power on, the first coil assembly 51 works, generates electromagnetic field, the electromagnetic field generated by the first coil assembly 51 can be upwards through the electric heating device 100, to be coupled with the pot at the heating area 411, provides electromagnetic heating function for the heating area 411, simultaneously, the control device controls one of the two electric heating parts 2 independent work.This can when the cooking utensils 200 overheats, make part or all of the electric heating part 2 reduce power or stop working, thereby reducing the influence of the temperature of the electric heating device 100 to the first coil assembly 51, so that the proportion of electromagnetic heating and electric heating can be flexibly adjusted according to different cooking needs, realize more accurate temperature control and heating effect.
