A flange 121 is arranged at a position of the heat-insulating cover 120 corresponding to the surrounding rib 112, and particularly, referring to fig. 4, the shape of the flange 121 is substantially the same as that of the surrounding rib 112. The flange 121 can enclose a wiring opening 122 so that the wiring terminal 111 can be connected to a control circuit of the cooking appliance through the heat retaining cover 120.

The flange 121 is preferably provided to extend toward the heating plate 110 so as to effectively block liquid such as water or soup overflowing from the inner pot 200 from flowing into the connection terminal 111 along the sidewall of the heat insulating cover 120 during the use or overflow test of the cooking appliance, thereby further ensuring the waterproof effect on the connection terminal 111.

Referring to fig. 1 and 2, along the radial direction of the heating plate 110, the surrounding rib 112 is located on the inner side of the flange 121 and is spaced from the flange 121, so that the wiring terminal 111 can be protected by two protective barriers, the waterproof effect is ensured, the installation between the heating plate 110 and the heat-insulating cover 120 is facilitated, and the assembly interference is avoided.

It is understood that, in the embodiment not shown, the turned-over edge 121 may be disposed inside the circumferential rib 112 and spaced apart from the circumferential rib 112 in the radial direction of the heat generating plate 110. The structure can form two protective barriers for the wiring terminal 111, ensure the waterproof effect, facilitate the installation between the heating plate 110 and the heat preservation cover 120 and avoid the generation of assembly interference.

That is, in order to achieve a better waterproof effect, one of the surrounding rib 112 and the turned-up edge 121 may be disposed to be located inside the other in the radial direction of the heat generating plate 110, and the surrounding rib 112 and the turned-up edge 121 may be disposed at an interval.

Considering the volume of the cooking appliance and the blocking effect of the turned-up edge 121 on the overflowing liquid in the inner pot 200, the height H of the turned-up edge 121 is preferably designed to satisfy: h is more than or equal to 2.0mm, so that the volume of the cooking utensil can be controlled conveniently while liquid overflowing from the inner pot 200 is prevented from entering the wiring terminal 111.

With reference to fig. 2, the turned-over edge 121 extends towards the heating plate 110, and the overlapped height of the turned-over edge 121 and the surrounding rib 112 of the heating plate 110 is h along the height direction of the heat insulation cover 120. In order to ensure the effective protection height of the two protective barriers formed by the joint action of the surrounding rib 112 and the heat preservation cover 120, so as to effectively ensure the waterproof effect on the wiring terminal 111, h is preferably designed to satisfy: h is more than or equal to 2.0mm and less than or equal to H.

At the bottom of the heat-retaining cover 120, a groove 123 may be provided which extends in the circumferential direction of the heat-retaining cover 120, with particular reference to fig. 2 and 4. The groove 123 can play a role in storing liquid overflowing from the inner pot 200 together, so that the liquid is prevented from flowing into the wiring terminal 111. The groove 123 is preferably designed as an annular groove continuously distributed along the circumference of the heat-insulating cover 120 to effectively improve the water storage capacity of the groove 123.

In order to effectively improve the water storage capacity of the groove 123 and increase the difficulty of the liquid in the groove 123 flowing to the connection terminal 111, the distance s between the bottom surface of the groove 123 and the bottom surface of the heat-retaining cover 120 is preferably designed to satisfy: s.gtoreq.2.0 mm, see in particular FIG. 2.

At least part of the turned-up edge 121 is connected to the inner edge of the groove 123 in the radial direction of the heat-retaining cover 120. That is to say, the turned-over edge 121 extending to the heating plate 110 may be provided at least at the inner edge of the groove 123 corresponding to the surrounding rib 112, so as to improve the water storage capacity of the groove 123 to some extent, and further facilitate the waterproof protection of the wire connecting terminal 111.

With continued reference to FIG. 2, the flange 121 is connected to the inner edge of the recess 123 by a generally horizontal connecting section 126 to facilitate the positioning of the flange 121.

Preferably, the surrounding rib 112 of the heat generating plate 110 abuts against the connecting section 126 to effectively block the accumulated water in the groove 123 from flowing into the connection terminal 111.

Referring to fig. 1 and 4, in order to discharge accumulated liquid in the groove 123 in time and prevent the accumulated liquid in the groove 123 from overflowing to the terminal 111, one or more water discharge holes 124 may be disposed in the groove 123. The shape, number, distribution position and mode of the drainage holes 124 can be set according to actual requirements.

Preferably, a downward extending flange 125 is disposed at the edge of the drainage hole 124, that is, the flange 125 extends toward the outer surface of the bottom side of the heat-insulating cover 120, so that the accumulated liquid in the groove 123 can smoothly flow out along the drainage hole 124, and the drainage efficiency of the drainage hole 124 for the accumulated liquid in the groove 123 is ensured, so as to further implement the waterproof protection for the wire terminal 111.

During the use of the cooking appliance or the overflow test, there may be a portion of the liquid overflowing from the inner pot 200 flowing downward from the gap between the heat generating plate 110 and the heat insulating cover 120. In order to effectively reduce the flow speed of the liquid, the distance d between the outermost edge of the heat generating tray 110 and the heat insulating cover 120 in the radial direction of the heat generating tray 110 is preferably designed to satisfy: d is less than or equal to 5.0mm, and particularly refer to figure 2. Thus, the outermost edge of the heating plate 110 can generate a certain blocking effect on the liquid overflowing from the inner pot 200 of the cooking appliance, the flowing speed of the overflowing liquid is effectively reduced, and the liquid is prevented from flowing to the connecting terminal 111 after being collided to the heat preservation cover 120 at a higher speed and then flowing over the flanging 121.
