[0002] Due to many advantages such as fast heating speed and high thermal efficiency, electromagnetic heating technology is widely used in household appliances.

[0003] A common electromagnetic heating coil is made by winding a copper wire around a bracket. The assembly process is complex and there are certain requirements for the number of turns of the coil and the winding firmness. For a low-power electromagnetic heating coil, the copper wire used is thinner, and the assembly difficulty is even greater. In the prior art, there is also a process of directly stamping a thin-film coil on a bracket to make an electric heating coil. However, the thin-film coil of this structure is prone to slipping out of the bracket, affecting normal use. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an installation structure of an electromagnetic heating coil disk to solve the above problems.

[0005] According to one aspect of the utility model, an installation structure of an electromagnetic heating coil disk is provided, including: an insulating bracket, an adhesive layer, and a coil. The coil is in a planar spiral structure, and the inner side and the outer side of the coil respectively have connection terminals. An installation groove corresponding to the coil is arranged on the top surface of the insulating bracket. The installation groove includes a first groove body and a second groove body. The first groove body is arranged in the middle of the installation groove, and the second groove body is arranged on both sides of the top of the first groove body. A plurality of infiltration grooves are arranged on the bottom surface of the coil. The adhesive layer is arranged between the installation groove and the coil.

[0006] In some embodiments, the thickness of the coil is greater than the depth of the installation groove.

[0007] In some embodiments, the width of the coil is equal to the width of the first groove body.

[0008] In some embodiments, the infiltration grooves are arranged towards the bottom surface of the first groove body.

[0009] In some embodiments, the thickness of the coil is 0.5 mm to 1 mm.

[0010] In some embodiments, the adhesive layer is silicone glue.

[0011] In some embodiments, the cross section of the infiltration groove is tooth-shaped.

[0012] In some embodiments, the cross section of the infiltration groove is wavy.

[0013] Compared with the prior art, the beneficial effects of the present application are as follows:

[0014] In the present application, the coil is fixed on the insulating bracket by using an adhesive layer. The bottom surface of the coil is provided with infiltration grooves, which can increase the contact area with the adhesive layer. Moreover, the adhesive layer in the second groove further helps to fix the lower sides of the coil, fixing the coil to the greatest extent and preventing the coil from slipping out of the insulating bracket. This structure is assembled quickly and firmly, improving the assembly efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Refer to Figures 1 to 4 , the present application provides an installation structure of an electromagnetic heating coil disk, including: an insulating bracket 1, an adhesive layer 2, and a coil 3. The coil 3 has a planar spiral structure, and the inner and outer sides of the coil 3 are respectively provided with terminal ends. The top surface of the insulating bracket 1 is provided with an installation groove corresponding to the coil 3. The installation groove includes a first groove body 4 and a second groove body 5. The first groove body 4 is arranged in the middle of the installation groove, and the second groove body 5 is arranged on both sides of the top of the first groove body 4. The bottom surface of the coil 3 is provided with a plurality of infiltration grooves 6, and the adhesive layer 2 is arranged between the installation groove and the coil 3.

[0021] In some embodiments, the thickness of the coil 3 is greater than the depth of the installation groove. After the coil 3 is fixed in the installation groove, the middle and upper parts of the coil 3 are higher than the surface of the insulating bracket 1.

[0022] In some embodiments, the width of the coil 3 is equal to the width of the first groove body 4. The lower part and the bottom surface of the coil 3 can enter the first groove body 4, and the coil 3 is fixed in cooperation with the adhesive layer 2 to prevent the installation position of the coil 3 from shifting.

[0023] In some embodiments, the infiltration groove 6 is arranged towards the bottom surface of the first groove body 4.

[0024] In some embodiments, the thickness of the coil 3 is 0.5 mm to 1 mm.

[0025] In some embodiments, the adhesive layer 2 is silicone glue. The silicone glass glue has strong adhesion, high tensile strength, and at the same time has weather resistance, vibration resistance, moisture resistance, odor resistance, and can adapt to large temperature changes. It is suitable for bonding the coil 3 in the installation groove.

[0026] In the first embodiment, the cross-section of the infiltration groove 6 is tooth-shaped.

[0027] In the second embodiment, the cross-section of the infiltration groove 6 is wavy.

[0028] The specific assembly principle of this application: Add the adhesive layer 2 into the first groove body 4, then place the coil 3 in the first groove body 4, apply pressure to the surface of the coil 3 so that the coil 3 moves down a certain distance in the first groove body 4. During the downward movement, a part of the adhesive layer 2 in the first groove body 4 will enter the infiltration groove 6, and the other part of the adhesive layer 2 is squeezed into the second groove body 5 and contacts both sides of the middle part of the coil 3. After waiting for the adhesive layer 2 to cure, the adhesive layer 2 fixes the middle and lower parts of the coil 3 at the same time.

[0029] In this application, the coil 3 is fixed on the insulating bracket 1 by using the adhesive layer 2. The infiltration groove 6 is arranged on the bottom surface of the coil 3, which can increase the contact area with the adhesive layer 2. And the adhesive layer 2 in the second groove body 5 also further helps to fix both sides of the lower part of the coil 3, fixing the coil 3 to the greatest extent and preventing the coil 3 from disengaging from the insulating bracket 1. This structure is assembled quickly and firmly, improving the assembly efficiency.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
