The electromagnetic stove generates heat directly at the bottom of a pot without a fire or conduction heating, and its heat efficiency is greatly improved. The electromagnetic stove is widely used due to its high efficiency and energy-saving performance.

[0003] The main structure of the electromagnetic stove includes a bracket, an electromagnetic heating coil and a pot body. The electromagnetic heating coil is assembled on the inner side of the bracket and is distributed around the outer side of the pot body. The bracket in the prior art generally includes a horizontal plate, a rib and a fixed plate. When the bracket is assembled, the assembly is mainly based on the horizontal plate and relies on manual experience. This assembly method leads to poor position precision of the rib. After the coil is assembled on the bracket, the gap between the coil and the pot body is not uniform in size. The size of the heating gap affects the energy-saving effect of the electromagnetic stove.

[0004] To solve the above problems, the present application provides an energy-saving electromagnetic stove and an assembly gap control method of the energy-saving electromagnetic stove. SUMMARY

[0005] In view of the problems in the prior art, the present application provides the following technical solutions: In one aspect, an energy-saving electromagnetic stove is provided, which includes a pot body, a bracket and an electromagnetic heating coil. One end of the pot body extends axially to form a protruding portion. The electromagnetic heating coil is assembled on the inner side of the bracket and is distributed around the outer side of the protruding portion of the pot body. The bracket includes a horizontal plate, a fixed plate and a plurality of ribs. A plurality of clamping blocks provided on the ribs are sequentially assembled with a plurality of clamping grooves provided on the same horizontal plate. A plurality of clamping grooves provided on the ribs are assembled with the same fixed plate. Magnetic strips are provided on the ribs which are spaced apart. The inner side of each rib is provided with a plurality of inner edge points A. A groove body is provided between each two adjacent inner edge points A. The electromagnetic heating coil is distributed in the groove body. The plurality of inner edge points A form an envelope line L. The gap between the envelope line L and the outer edge of the pot body is equal in the X-axis, Y-axis and Z-axis dimensions, with the outer edge of the pot body as a positioning reference.

[0006] As a preferred embodiment of the above technical solution, a layer of glass fiber filaments is assembled on the outer side of the pot body.

[0007] As a preferred embodiment of the above technical solution, a through groove is provided on the rib, and the magnetic strip is assembled in the through groove.

[0008] In another aspect, a method for controlling the assembly gap of an energy-saving electromagnetic range is provided, which adjusts the gap between the pot and the bracket, and comprises the following steps: S1. Pot positioning: place the convex part of the pot upwards on the assembly platform and fix it; S2. Horizontal plate positioning: place the horizontal plate on one side of the convex part of the pot, so that the center of the convex part of the pot coincides with the center of the horizontal plate; S3. Rib assembly: take the outer edge of the pot as the positioning reference, adjust the ribs in X-axis, Y-axis and Z-axis three dimensions to the assembly position, S3-1. After the clamping blocks on the plurality of ribs are sequentially clamped and matched with the plurality of clamping grooves on the same horizontal plate, they are fixed by glue, and the envelope line L formed by the plurality of inner edge points A on the inner side of the ribs is equal to the gap of the outer edge of the pot. S4. Electromagnetic heating coil assembly: assemble the electromagnetic heating coil on the inner side of the ribs and distribute it around the outer side of the convex part of the pot.

[0009] As a preferred embodiment of the above technical solution, the S3. Rib assembly further comprises S3-2. The second clamping groove opened on the plurality of ribs is sequentially clamped and matched with the same fixed plate, and then fixed by glue.

[0010] As a preferred embodiment of the above technical solution, in the S4. Electromagnetic heating coil assembly, the electromagnetic heating coil is assembled in the groove body opened on the inner side of the ribs, and is fixed in position by glue.

[0011] As a preferred embodiment of the above technical solution, it further comprises S5. Magnetic strip assembly: assemble the magnetic strip on the rib and fix it in position by glue.

[0012] The beneficial effects of the present application are: 1. In the energy-saving electromagnetic range of the technical solution, the envelope line L formed by the plurality of inner edge points A on the inner side of the ribs is equal to the gap of the outer edge of the pot, taking the outer edge of the pot as the positioning reference, adjusting the ribs in X-axis, Y-axis and Z-axis three dimensions, after the electromagnetic heating coil is assembled in the groove body on the inner side of the ribs, the heating gap at any position between the electromagnetic heating coil and the pot is unified, the heating efficiency of the electromagnetic heating coil is consistent, and the electromagnetic heating coil does not act on the body during work, but acts on the pot, achieving the effect of energy saving.

[0013] 2. In the prior art, the assembly method based on the horizontal plate mainly relies on manual experience, which leads to the problem of poor rib position precision, and in actual use, in order to ensure the uniformity of the heating gap, the position of the rib needs to be adjusted when the electromagnetic heating coil is assembled, but the bracket in the prior art cannot be adjusted in position after assembly, which cannot meet the actual use requirements.

[0014] The assembly gap control method of the energy-saving induction cooker in this technical solution first places a horizontal plate on one side of the protruding part of the pot body, controlling the center of the protruding part of the pot body to coincide with the center of the horizontal plate. Then, using the outer edge of the pot body as the positioning reference, the position of the rib is adjusted in three dimensions: X-axis, Y-axis, and Z-axis, until the envelope L formed by multiple inner edge points A on the inner side of the rib is equal to the gap of the outer edge of the pot body, and the final position of the rib is fixed. By adjusting the assembly gap between the pot body and the bracket during the assembly process of the bracket, the envelope L formed by multiple inner edge points A on the inner side of the rib is equal to the gap of the outer edge of the pot body. After the electromagnetic heating coil is assembled on the inner side of the rib, the heating gap at any position between the electromagnetic heating coil and the pot body is unified, and the position of the rib does not need to be adjusted again when assembling the electromagnetic heating coil.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example 1 like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the energy-saving induction cooker includes a pot body 10, a bracket 30, and an electromagnetic heating coil 40. In this embodiment, the electromagnetic heating coil 40 is a copper resonant coil. One end of the pot body 10 extends axially to form a protrusion. The electromagnetic heating coil 40 is mounted on the inner side of the bracket 30 and distributed around the outer side of the protrusion of the pot body 10. The bracket 30 includes a horizontal plate 31, a fixed plate 33, and multiple ribs 32. The locking blocks 323 on the multiple ribs 32 are sequentially assembled with multiple slots 311 on the same horizontal plate 31. The slots 324 on the multiple ribs 32 are assembled with the same fixed plate 33. Magnetic strips 34 are provided on the spaced ribs 32. To achieve the assembly of the magnetic strips 34, through slots 322 are provided on the ribs 32. The magnetic strips 34 are assembled in the through slots 322. The magnetic strips 34 have the function of focusing magnetic energy and supplementing the magnetic field of the electromagnetic heating coil 40, reducing the attenuation of the magnetic field of the electromagnetic heating coil 40 due to the outward expansion of the magnetic field, making the magnetic field uniform and the heating of the induction cooker more uniform. Each rib 32 has multiple inner edge points A on its inner side, and a groove 321 is provided between every two adjacent inner edge points A. Electromagnetic heating coils 40 are distributed within the grooves 321. The multiple inner edge points A form an envelope L. Using the outer edge of the pot body 10 as a positioning reference, the gap between the envelope L and the outer edge of the pot body 10 is equal in the X, Y, and Z axes. The gap is... Figure 5 δ in.

[0019] In this technical solution, the energy-saving induction cooker uses the outer edge of the pot body 10 as a positioning reference. In the three dimensions of X-axis, Y-axis, and Z-axis, the envelope line L formed by multiple inner edge points A on the inner side of the rib 32 is equal to the gap with the outer edge of the pot body 10. After the electromagnetic heating coil 40 is assembled in the groove 321 on the inner side of the rib 32, the heating gap at any position between the electromagnetic heating coil 40 and the pot body 10 is unified, ensuring that the heating efficiency of the electromagnetic heating coil 40 is consistent. During the operation, the electromagnetic heating coil 40 does not act on the main body, but acts entirely on the pot body 10, thus achieving the effect of energy saving.

[0020] like Figure 1 , Figure 2 As shown, a glass fiber layer 20 is fixedly mounted on the outer side of the pot body 10. The glass fiber layer 20 is a soft material with a thickness of less than 1 mm. The setting of the glass fiber layer 20 can negate the influence of the size of the gap between the pot body 10 and the bracket 30. At the same time, the setting of the glass fiber layer 20 can buffer the direct friction caused by the rigid contact between the electromagnetic heating coil 40 and the pot body 10, reduce component wear, and suppress electromagnetic radiation leakage, making the electromagnetic induction of the coil more concentrated and improving heating efficiency. The glass fiber layer 20 has low thermal conductivity, which can insulate the electromagnetic heating coil 40 and prevent the high temperature of the pot body 10 from being conducted to the electromagnetic heating coil 40, avoiding the coil from aging or being damaged due to overheating. As an excellent insulator, the glass fiber layer 20 can isolate the current path between the pot body 10 (leaking electricity) and the electromagnetic heating coil 40, eliminate the risk of leakage, and ensure safe use.

[0021] In the existing technology, the assembly method, which mainly relies on manual experience and uses a horizontal plate as the assembly basis, leads to poor rib position accuracy. In actual use, in order to ensure the uniformity of the heating gap, the rib position needs to be adjusted during the assembly of the electromagnetic heating coil. However, the bracket in the existing technology cannot be adjusted according to the actual use once the assembly is completed, and cannot meet the actual use requirements.

[0022] To address the above problems, this application proposes an assembly gap control method for an energy-saving induction cooker. The control method adjusts the gap between the pot body 10 and the bracket 30, including the following steps: In this embodiment, the adhesive used is epoxy resin. S1. Positioning of pot body 10: Place the protruding part of pot body 10 on the assembly platform with the protrusion facing upward and fix it; S2. Positioning of horizontal plate 31: Place horizontal plate 31 on one side of the protrusion of pot body 10, so that the center of the protrusion of pot body 10 coincides with the center of horizontal plate 31; S3. Rib 32 Assembly: Using the outer edge of the pot body 10 as the positioning reference, adjust the rib 32 to the assembly position in the three dimensions of X-axis, Y-axis and Z-axis. S3-1. After the locking blocks 323 on the multiple ribs 32 are sequentially engaged with the multiple slots 311 on the same horizontal plate 31, they are fixed with glue. The assembly position is that the envelope line L formed by the multiple inner edge points A on the inner side of the rib 32 is equal to the gap between the outer edge of the pot body 10. S4. Assembly of electromagnetic heating coil 40: The electromagnetic heating coil 40 is assembled on the inner side of the rib 32 and distributed around the outer side of the protrusion of the pot body 10.

[0023] The assembly gap control method of the energy-saving induction cooker in this technical solution is as follows: First, the horizontal plate 31 is placed on one side of the protruding part of the pot body 10, and the center of the protruding part of the pot body 10 is controlled to coincide with the center of the horizontal plate 31. Then, with the outer edge of the pot body 10 as the positioning reference, the position of the rib 32 is adjusted in three dimensions: X-axis, Y-axis and Z-axis. The adjustment is made until the envelope line L formed by multiple inner edge points A on the inner side of the rib 32 is equal to the gap with the outer edge of the pot body 10, and the final position of the rib 32 is fixed. By adjusting the assembly gap between the pot body 10 and the bracket 30 during the assembly process of the bracket 30, the envelope L formed by multiple inner edge points A on the inner side of the rib 32 is equal to the gap on the outer edge of the pot body 10. After the electromagnetic heating coil 40 is assembled on the inner side of the rib 32, the heating gap at any position between the electromagnetic heating coil 40 and the pot body 10 is unified. The position of the rib 32 does not need to be adjusted during the assembly of the electromagnetic heating coil 40. This solves the problem in the prior art that the assembly method, which mainly relies on manual experience and uses a horizontal plate as the assembly basis, results in poor rib position accuracy. In actual use, in order to ensure the uniformity of the heating gap, the position of the rib 32 needs to be adjusted during the assembly of the electromagnetic heating coil 40. However, the bracket in the prior art cannot be adjusted after assembly, which cannot meet the actual use requirements.

[0024] The assembly gap control method for the energy-saving induction cooker in this application, in order to ensure the stable assembly of the ribs 32 and at the same time ensure the accuracy of its assembly, S3. The assembly of the ribs 32 also includes S3-2. After the slots 324 opened on the multiple ribs 32 are sequentially engaged with the same fixing plate 33, they are fixed with glue.

[0025] In the bracket 30 of this application, the horizontal plate 31 limits the bottom of the rib 32 to determine the assembly base, and the fixed plate 33 limits the upper part of the rib 32 to further enhance the fixing effect. The setting of fixing the position of the rib 32 by the cooperation of the horizontal plate 31 and the fixed plate 33 ensures the stability of the position of the bracket 30 after assembly.

[0026] The energy-saving induction cooker assembly gap control method in this application, S4. During the assembly of the electromagnetic heating coil 40, the electromagnetic heating coil 40 is assembled in the groove 321 opened on the inner side of the rib 32 and fixed in position by glue; to achieve stable assembly of the electromagnetic heating coil 40 on the inner side of the rib 32, to ensure uniform heating gap, thereby ensuring the heating efficiency and uniformity of the induction cooker, avoiding energy waste, and at the same time ensuring the stability of the position of the electromagnetic heating coil 40, so as to stably exert the synergistic effect of the magnetic strip 34, the electromagnetic heating coil 40 and the glass fiber layer 20, to avoid functional failure, reduce vibration and noise, and extend the life of components.

[0027] The assembly gap control method for energy-saving induction cookers also includes S5. Magnetic strip 34 assembly: Magnetic strip 34 is assembled on rib 32 and fixed in position with glue; ensuring the stability of the position of magnetic strip 34 on bracket 30, avoiding magnetic field dispersion caused by magnetic strip 34 position displacement, affecting the magnetic focusing effect, and at the same time avoiding friction or signal interference between pot body 10 and electromagnetic heating coil 40 caused by magnetic strip 34 displacement.

[0028] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
