As shown in fig. 5, the cooling gas can enter the air guiding gap 708 through the air inlet slot 705, enter the coil 6, and then respectively transmit airflow to the inner coil 61 and the outer coil 62 at two sides for heat dissipation.

The air guide gap 708 can enable cooling gas to enter the coil 6 and then flow towards two sides respectively, so that a three-dimensional heat dissipation effect is achieved, and a better heat dissipation effect is achieved.

The coil 6 is divided into two parts, i.e., an inner coil 61 and an outer coil 62, by the air guide gap 708 to form two independent heating areas, thereby turning food cooked in the inner pot 1.

As shown in fig. 3 and 4, the coil tray cover 5 covers the coil tray seat 7. The bottom surface 50 of the coil cover 5 is provided with a plurality of hooks 51 and a plurality of studs 52. The hook 51 includes a first connection portion 511 connected to the bottom surface 50 and a first locking portion 512 horizontally protruding from one side of the first connection portion 511. In the present embodiment, all the first latching portions 512 protrude in the clockwise direction when viewed from the bottom surface facing upward, and in fact, when the coil cover 5 is placed on the bottom surface facing downward, the first latching portions 512 protrude in the counterclockwise direction. The first connecting portion 511 is provided with a first rib 513 connected to the bottom surface 50 on a side thereof away from the first locking portion 512, so as to enhance the strength. The studs 52 are located between the outer sidewall 501 and the arc-shaped rib 502 and are flush with the bottom surfaces of the outer sidewall 501 and the arc-shaped rib 502, so that the studs 52 can be pressed against the platform 70 of the coil seat 7. The hooks 51 are also disposed between the outer sidewall 501 and the arc-shaped ribs 502, and are alternately disposed with the studs 52.

The upper surface of the platform 70 of the coil disc seat 7 is further provided with a buckle 71 and a mounting hole 706, and the structure of the buckle 71 is the same as that of the buckle hook 51 of the coil disc cover 5, and the buckle 71 includes a second connecting portion 711, a second buckle portion 712 horizontally protruding from one side of the second connecting portion 711, and a second reinforcing rib 713 connecting the other side of the second connecting portion 711 and the upper surface of the platform 70. All the second catching portions 712 protrude in the counterclockwise direction. Alternatively, all the first locking portions 512 may protrude in the counterclockwise direction, and all the second locking portions 712 may protrude in the clockwise direction.

Referring to fig. 5, in assembly, after the coil 6 is fixed on the coil base 7, the coil cover 5 is covered on the coil base 7, the outer sidewall 501 and the arc-shaped rib 502 are pressed against the upper surface of the platform 70, the coil cover 5 is rotated counterclockwise, so that the first fastening portion 512 of the hook 51 of the coil cover 5 and the second fastening portion 712 of the fastener 71 of the coil base 7 are fastened to each other, the stud 52 of the coil cover 5 is aligned with the mounting hole 706 of the coil base 7 up and down, and then the coil cover 5 is fixed on the coil base 7 by fastening a screw (not shown) from the bottom of the coil base 7 through the mounting hole 706 to the stud 52.

Since the coil disk cover 5 is made of a heat-resistant and rigid material, preferably PPS plastic (polyphenylene sulfide), the cost is high, and the thickness design is thin. Although the coil disc cover is made of high-temperature resistant material, if an abnormal high-temperature condition is met, the coil disc cover 5 is easy to deform and warp, and is fixed on the stud 52 on the coil disc cover 5 by a screw through the mounting hole 706 on the coil disc seat 7; meanwhile, the coil disk cover 5 and the coil disk seat 7 are synchronously provided with the buckle hook 51 and the buckle 71 which are in lap joint. The coil cover 5 and the coil base 7 are combined together in a screw and buckle structure, so that the problem that the coil cover 5 is deformed and warped is solved.

Referring to fig. 6, fig. 6 shows an upward view of the coil base 7. The coil base 7 is provided with the bottom wall 73 and the side walls 74, wherein the side walls 74 extend downwards from the bottom surface of the coil base 7, are arranged around the outer edge of the coil base 7 in a circle, and are located at the outer edge of the bottom wall 73. Please note that, the positioning of the side wall 74 at the outer edge of the bottom wall 73 includes two cases of overlapping and non-overlapping the side wall 74 and the bottom wall 73.

Because the coil disc seat 7 needs to bear larger pressure from the inner pot 1, the whole coil disc seat 7 is basically horizontally placed, and the inward convex radian is smaller; as mentioned above, the

ribs

503, 504 and 505 of the coil cover 5 press against the winding rib 702 of the coil base 7, and the winding rib 702 is located on the upper surface of the bottom wall 73. The middle portion 730 of the bottom wall 73 is subjected to a greater pressure. And the supporting point of the coil base 7 supported by the heat-insulating cover 2 is near the side wall 74 at the edge. In order to avoid the deformation of the middle portion 730 of the bottom wall 73, it is necessary to transmit the force applied to the middle portion 730 of the bottom wall 73 to the edge, and avoid the deformation of the middle portion 730 of the coil base 7, and the coil base 7 is provided with the reinforcing rib 75. The middle portion 730 of the bottom wall 73 is connected with the side wall 74 through the reinforcing rib 75, so that the coil disc seat 7 is prevented from deforming after bearing pressure, and the service life is prolonged.

The bottom wall 73 is further provided with a plurality of guide slots 731 for accommodating magnetic strips (not shown). In this embodiment, the bottom wall 73 includes 6 guide slots 731. The guide slots 731 extend radially from the center to the edge of the coil base 7. Each guide slot 731 has two opposing radially extending side walls 732. The rib 75 connects the side wall 732 and the side wall 74, and the bottom surface of the side wall 732 is higher than the bottom surface of the side wall 74 (fig. 6 shows that the bottom surface of the side wall 732 is lower than the bottom surface of the side wall 74 because the bottom surface faces upward), so the bottom surface of the rib 75 is in a slope transition. The side wall 74 is further provided with a screw post 76, and the center of the screw post 76 is provided with threads. The screw post 76 is located on the side wall 74 in the area corresponding to the guide groove 731, i.e. between the two ribs 75. The screw post 76 has a high structural strength and can bear the locking force of the screw. Screws (not shown) are fastened to the screw posts 76 through the heat-retaining cover 2, thereby fixing the coil base 7 to the heat-retaining cover 2.

As shown in fig. 6, the side wall 74 of the coil base 6 is used to press against the bottom of the heat-insulating cover 2. The bottom of the side wall 74 is provided at intervals with projections 740 projecting further downward, and the bottom surface of the portion where the projections 740 are not provided is defined as a first mating surface 741; the bottom surface of the protrusion 740 defines a second mating surface 742.

The heat preservation cover 2 in fig. 7 is viewed from an upward bottom surface, and the bottom support platform 20 of the heat preservation cover 2 is substantially annular, and concave-convex structures are formed along the annular direction at intervals for enhancing the strength of the support platform 20. The outward protruding portion is defined as a sinking platform 21, and the portion between two adjacent sinking platforms 21 is defined as a boss 22. As shown in fig. 5 and 8, the first mating surface 741 of the side wall 74 presses against the upper surface of the boss 22; the second mating surfaces 742 of the side walls 74 press against the upper surface of the sinking platform 21. The bottom surface of the side wall 74 is basically attached to the concave-convex structure of the heat-insulating cover 2, so that the gap between the bottom surface of the coil base 7 and the supporting platform 20 of the heat-insulating cover 7 is reduced as much as possible.

When the heat-insulating cover 2 works, hot air flows enter the inner side of the side wall 74 from the hole in the center of the supporting platform 20 of the heat-insulating cover 2, and due to the blocking of the side wall 74, the hot air is basically blocked and cannot enter the inner side of the heat-insulating cover 2, and the hot air cannot enter the coil 6 between the coil disk cover 3 and the coil disk seat 7, so that the influence of the hot air on the coil 6 can be avoided. The blocked hot air flow will exit the cooking utensil from the aforementioned base 4 located under the heat-retaining cover 2, dissipating heat to the outside. The side wall 74 can effectively reduce the surface temperature rise of the coil 6, and avoid the damage caused by overhigh temperature rise. Meanwhile, the side wall 74 can play a role in reinforcing the coil disc seat 7, the contact area between the coil disc seat 7 and the heat-insulating cover 2 is enlarged, and the pressure-bearing performance of the heat-insulating cover 2 is improved.

Referring to fig. 3, 4 and 9, the coil cover 5 is fixed on the coil seat 7, and the outer sidewall 501 and the arc-shaped rib 502 are pressed against the upper surface of the platform 70. After the two are connected through the screw and the buckle, a gap still exists between the two, so that a waterproof structure is required to be correspondingly arranged to prevent water flowing down along the side wall of the inner pot 1 from entering the coil base 7 and burning out the coil 6.

Specifically, the coil seat 7 is provided with a circle of water blocking ribs 77 located outside the coil 6, and the water blocking ribs 77 are located inside the platform 70, that is, inside the arc-shaped ribs 502 of the assembled coil cover 5. This manger plate muscle 77 can set up to the whole circle, also can be not the whole circle, and the water-proof effects of whole circle can be more, can avoid water to get into 6 departments of coil. The platform 70 is further provided with a plurality of flow guiding surfaces 78, as shown in fig. 9, the flow guiding surfaces 78 are arranged on the outer ring of the platform 70 far away from the water retaining ribs 77 and are inclined downwards and outwards.

The coil base 7 is further provided with a plurality of water leakage grooves 79, and the water leakage grooves 79 are located at the lowest position of the flow guide surface 78, so that water can be drained conveniently. The water leakage groove 79 extends from the flow guiding surface 78 downward through the bottom wall 73 of the coil tray 7 and further extends along the outer side surface of the side wall 74 at the bottom side of the coil tray 7 (see fig. 6). The side wall 74 also serves as a water barrier to prevent water from entering the coil 6.

The supporting platform 20 of the heat-insulating cover 2 supports the side wall 74, and is provided with a water leakage hole 23 (see fig. 7) corresponding to the water leakage groove 79. The dripping water enters the platform 70 along the gap between the coil disk cover 5 and the coil disk seat 7, and because of the water blocking rib 77, the dripping water does not touch the coil 6. The accumulated water flows out of the coil disc seat 7 along the water leakage groove 79 on the outer side of the side wall 74, flows onto the base 4 along the water leakage holes 23 of the heat preservation cover 2, and flows out along other water drainage holes of the base 4.

Through the arrangement of the water retaining rib 77, the side wall 74, the flow guide surface 78, the water leakage groove 79 and the water leakage hole 23, the heat preservation cover 2 is enabled to drip water and flow out of the coil base 7, the coil 6 is prevented from touching water to cause damage, and the normal use of the cooking appliance is ensured.

Referring to fig. 10, fig. 10 shows another embodiment of the base 4, in which the base 4' is provided with a bottom wall 41, a side wall 42, a plurality of air inlet holes 43 and a plurality of heat dissipation holes, wherein the heat dissipation holes include a plurality of first heat dissipation holes 45, a plurality of second heat dissipation holes 46 and a plurality of third heat dissipation holes 47. The air inlet hole 43 is disposed at the rear end of the base 4' corresponding to the fan 14, and the heat dissipation holes 45, 46, 47 are distributed at the front end.

The third heat dissipation hole 47 is located at the front side of the front end, and extends forwards along the bottom wall 41 and further along the side wall 42 to form an arc-shaped divergent arrangement, so that the heat dissipation is more sufficient. The second heat dissipation holes 46 are located on two sides of the front end, and extend outwards along the bottom wall 41 and further along the side wall 42 to form an arc-shaped divergent arrangement. The first heat dissipation holes 45 are located at two sides of the bottom wall 41 and extend to the two sides, and the first heat dissipation holes 45 are integrally distributed at the middle and the front end of the bottom wall 41.

This cooking utensil's coil panel subassembly can produce more heat at the course of the work, and fan 14 drives the heat that coil panel subassembly surface produced to this base 4' internal surface, and partly heat distributes away through first louvre 45 that is close to the center on base 4 'at first, because first louvre 45 distributes to both sides limit, and the heat then distributes away from base 4' both sides. A part of the heat which does not flow out from the first heat dissipation holes 45 is continuously pushed outwards, and can be dissipated from the second heat dissipation holes 46 or from the third heat dissipation holes 47 near the front side. The second heat dissipation hole 46 and the third heat dissipation hole 47 are also disposed to dissipate heat to the edge of the cooking period and to the outside, without causing the problem of excessive temperature rise of the coil panel assembly.

In addition, the first heat dissipation hole 45 may be disposed slightly outward and forward to guide heat forward to the second and third heat dissipation holes 46 and 47.

The radiating holes 45, 46 and 47 of the base 4' are distributed in a radiating mode in multiple directions, so that the heat inside can be fully radiated, and the coil panel component is prevented from being damaged by high temperature.
