[0030] See Figures 1-7 , this utility model provides a cooking device with a floating cover assembly, including an inner pot 1, an upper cover 4, a cover assembly 2 and a coil pan assembly 3. The cover assembly 2 is movably arranged up and down at the bottom of the upper cover 4 and forms a receiving cavity, and movably seals the inner pot 1 up and down to form a closed cooking cavity 11. The coil pan assembly 3 is slidably connected to the upper cover 4 up and down and is located in the receiving cavity. The bottom wall of the coil pan assembly 3 abuts against the top wall of the cover assembly 2. Among them, the coil pan assembly 3 is used to heat the cover assembly 2. The coil pan assembly 3 is slidably connected to the upper cover 4 up and down, and the bottom wall of the coil pan assembly 3 abuts against the top wall of the cover assembly 2. Specifically, the cooking cavity 11 has a pressurized state and a non-pressurized state. When the cooking cavity 11 is in the pressurized state, the pressure in the cooking cavity 11 increases, and the high air pressure drives the cover assembly 2 to move upward. During the upward movement of the cover assembly 2, it can drive the coil pan assembly 3 to move upward relative to the upper cover 4, so that the coil pan assembly 3 is always in contact with the cover assembly 2, and the electromagnetic coil 32 in the coil pan assembly 3 and the cover assembly 2 always maintain a stable distance. The coil pan assembly 3 of this solution can slide up and down relative to the upper cover 4, and is applicable to rice cookers with a cover assembly 2 that can move up and down, and is also applicable to rice cookers with a cover assembly 2 that is always fixed. The application range of the product is large.

[0031] Further, at least one first through hole 41 is provided on the upper cover 4, and at least one suspension shaft 311 is provided on the coil pan assembly 3. The suspension shaft 311 is slidably arranged up and down in the first through hole 41. By the up and down sliding of the suspension shaft 311 in the first through hole 41, the coil pan assembly 3 can move up and down together with the cover assembly 2.

[0032] Further, a limiting member 312 is provided at the top of the suspension shaft 311. The suspension shaft 311 penetrates through the first through hole 41, and the bottom wall of the limiting member 312 abuts against the top wall of the upper cover 4. The limiting member 312 can limit the position of the coil pan assembly 3 and prevent the suspension shaft 311 from disengaging from the first through hole 41. Specifically, the limiting member 312 can be a large-headed screw. An installation hole is provided on the top wall of the suspension shaft 311, and the large-headed screw is fixedly installed in the installation hole.

[0033] Further, the cooking device includes a first elastic reset member 5. One end of the first elastic reset member 5 is connected to the bottom wall of the upper cover 4, and the other end is connected to the top wall of the coil pan assembly 3.

[0034] Further, the coil disc assembly 3 includes a coil disc 31, an electromagnetic coil 32, and a magnet 33. The electromagnetic coil 32 and the magnet 33 are both disposed on the coil disc 31. The bottom wall of the coil disc 31 abuts against the top wall of the cover plate assembly 2. The suspension shaft 311 is disposed on the coil disc 31. There are three electromagnetic coils 32, which are arranged on the coil disc 31, and there is a gap between the electromagnetic coil 32 and the bottom wall of the coil disc 31.

[0035] Further, the first elastic reset member 5 is sleeved on the suspension shaft 311, and the first elastic reset member 5 abuts against the top wall of the coil disc 31. Specifically, the first elastic reset member 5 can be a spring. When the cooking cavity 11 is in a pressure-up state, the pressure in the cooking cavity 11 increases. The high air pressure drives the cover plate assembly 2 to move upward. During the upward movement of the cover plate assembly 2, it can drive the coil disc assembly 3 to move upward relative to the upper cover 4, so that the coil disc assembly 3 always contacts the cover plate assembly 2, and the electromagnetic coil 32 in the coil disc assembly 3 and the cover plate assembly 2 always maintain a stable distance. When the cooking cavity 11 is in a non-pressure-up state, the pressure in the cooking cavity 11 decreases, the cover plate assembly 2 moves downward to reset, and at the same time, the first elastic reset member 5 drives the coil disc assembly 3 to also move downward to reset, so that the coil disc assembly 3 always contacts the cover plate assembly 2, and the electromagnetic coil 32 in the coil disc assembly 3 and the cover plate assembly 2 always maintain a stable distance.

[0036] Further, a ring-shaped convex block 313 is provided on the top wall of the coil disc 31. The ring-shaped convex block 313 is located on the outer circumference of the suspension shaft 311. The first elastic reset member 5 abuts against the top wall of the ring-shaped convex block 313. Specifically, the ring-shaped convex block 313 is arranged around the suspension shaft 311, and the inner side wall of the ring-shaped convex block 313 coincides with the outer side wall of the suspension shaft 311.

[0037] Further, a plurality of annularly distributed brackets 314 are provided on the top wall of the coil disc 31. Each bracket 314 is provided with a first groove for installing the electromagnetic coil 32. The magnet 33 is disposed on the top wall of the bracket 314. Specifically, each bracket 314 is provided with a magnet 33. The magnet 33 and the bracket 314 are fixedly connected. Each bracket 314 is provided with three radially distributed first grooves, and the three electromagnetic coils 32 are respectively embedded in the three first grooves. There is a gap between the electromagnetic coil 32 and the top wall of the coil disc 31.

[0038] Further, three first through holes 41 are circumferentially distributed on the upper cover 4, and three hanging shafts 311 are circumferentially distributed on the coil disk assembly 3. Each hanging shaft 311 is correspondingly connected to one of the first through holes 41, so that the up-and-down sliding of the coil disk assembly 3 is more stable.

[0039] Further, the cooking device includes a lock 6. The inner pot 1 has inner pot teeth 12, and the lock 6 has lock teeth 61. The top wall of the cover plate assembly 2 abuts against the bottom wall of the lock 6, and there is a gap between the bottom wall of the inner pot teeth 12 and the top wall of the lock teeth 61. When the cover plate assembly 2 moves upward to the maximum displacement, the bottom wall of the inner pot teeth 12 abuts against the top wall of the lock teeth 61. When the cooking cavity 11 is under pressure, the pressure in the cooking cavity 11 increases, and the high air pressure drives the cover plate assembly 2 to move upward. The cover plate assembly 2 drives the lock 6 to move upward together. When the cover plate assembly 2 moves upward to the maximum displacement, the top wall of the lock teeth 61 abuts against the bottom wall of the inner pot teeth 12, so that the cover plate assembly 2 and the lock 6 stop moving upward.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the invention.
