[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] See Figures 1-8 The assembly structure of this cooking appliance includes a coil assembly 1, a housing 2, and a lower cover 3. The coil assembly 1 and the lower cover 3 respectively cover the upper and lower sides of the housing 2. The upper and lower sides of the housing 2 are respectively provided with openings. A detachable connection part is provided between the coil assembly 1 and the lower cover 3. The coil assembly 1 and the lower cover 3 are connected by the detachable connection part to press the housing 2 between the coil assembly 1 and the lower cover 3, thereby fixing the housing 2.

[0027] The coil assembly 1 includes an integrally formed support ring 4, a side plate 5, and a coil 6 arranged sequentially in a vertical order. An inner cavity 7 is formed between the outer shell 2 and the lower cover 3. The side plate 5 and the coil 6 are disposed on the inner cavity 7. The support ring 4 covers the upper side of the outer shell 2, and the outer shell 2 is press-fitted between the support ring 4 and the lower cover 3.

[0028] It also includes an inner liner 8. The coil assembly 1 has a receiving cavity 9. The inner liner 8 is placed on the receiving cavity 9. There is a gap 10 between the bottom of the inner liner 8 and the coil 6, so that the bottom of the inner liner 8 does not contact the coil 6, so no heat is transferred to the coil 6. The temperature of the coil 6 is relatively low, preventing the coil 6 from being damaged due to high temperature.

[0029] The inner liner 8 has an outwardly folded flange 11 at the top. Several gaskets 12 are provided between the flange 11 and the support ring 4. The flange 11 is supported on the support ring 4 by the gaskets 12, so that a gap 10 is formed between the bottom of the inner liner 8 and the coil 6.

[0030] The size of the gap 10 is 2 to 15 mm. The size of the gap 10 changes with the thickness of the shim 12. The size of the gap 10 can be adjusted by replacing the shim 12 with one of different thicknesses, thereby adjusting the performance requirements.

[0031] The flange 11 has several positioning grooves 13 arranged in a ring. The gasket 12 is positioned on the positioning grooves 13, thereby fixing the gasket 12.

[0032] The disassembly connection part includes several fixing holes 21 arranged in a ring on the flange 11 and several fixing post holes 22 arranged in a ring on the lower cover 3. The fastener 14 passes through the fixing holes 21 and is fastened to the fixing post holes 22 to connect the coil assembly 1 and the lower cover 3. The fastener 14 is an extended screw and is vertically set on the inner cavity 7. The outer shell 2 is clamped by the coil assembly 1 and the lower cover 3 and then locked and fixed with extended screws. The structure is simple and easy to assemble.

[0033] The fixing hole 21 is located at the bottom of the positioning groove 13, and the bottom of the washer 12 presses against the screw head of the extension screw.

[0034] The upper and lower sides of the outer shell 2 are respectively provided with a first rolled edge 15 and a second rolled edge 16. The edge of the support ring 4 is provided with a support portion 17, and the edge of the lower cover 3 is provided with a support portion 18. The support ring 4 is supported on the first rolled edge 15 through the support portion 17, and the outer shell 2 is supported on the support portion 18 through the second rolled edge 16.

[0035] The bottom of the support ring 4 is provided with a first limiting edge 19, which is located inside the support part 17. The top of the lower cover 3 is provided with a second limiting edge 20, which is located inside the support part 18. The first rolled edge 15 abuts inward against the first limiting edge 19, and / or the second rolled edge 16 abuts inward against the second limiting edge 20, thereby positioning the outer shell 2 in all directions to prevent the outer shell 2 from becoming loose. In this embodiment, the second rolled edge 16 abuts inward against the second limiting edge 20. The support part 17 and the first limiting edge 19 together form a first step, and the support part 18 and the second limiting edge 20 together form a second step. The first rolled edge 15 is disposed on the first step, and the second rolled edge 16 is disposed on the second step.

[0036] The support ring 4, side plate 5, and wire reel 6 are integrally molded by plastic injection molding. The plastic injection molding of the support ring 4, side plate 5, and wire reel 6 into a single part can reduce costs and improve production efficiency.

[0037] The bottom of the coil 6 has several sets of winding protrusions 23 arranged in a ring, and winding grooves are formed between the winding protrusions 23. The enameled wire is connected to the coil 6 by winding on the winding groove. The enameled wire is one of the accessories of the electromagnetic coil assembly. This cooking appliance heats the inner pot 8 through the electromagnetic coil.

[0038] The cooking appliance is a rice cooker or an induction cooker. In this embodiment, the cooking appliance is a rice cooker, which is a multi-functional rice cooker that can be used as a rice cooker or an induction cooker.

[0039] The outer casing 2 is made of stainless steel.

[0040] The top opening of the inner liner 8 is covered by a top cover 24.
