Cooking appliances, such as electric steamers or electric stewing cups, generally include an inner pot and a water tank having a heating element disposed therein, the heating element generating steam through the heating water tank to heat food materials in the inner pot. Because the cooking time is longer, the cooking device can uniformly provide heat, and the nutrient substances in the food materials can be more fully separated out. However, when the water in the water tank is not added or the cooking time is too long, the existing cooking utensil is not provided with an element for preventing dry heating, so that the cooking utensil can be dry-heated, and the potential safety hazard is high.

In order to solve the above problems, as shown in fig. 1 to 8, the present application provides a cooking appliance capable of avoiding the excessive temperature of a water tank and reducing the potential safety hazard. The cooking utensil can be applied to an electric steamer, an electric stewing cup and the like.

As shown in fig. 1 to 3, in detail, the cooking appliance includes an inner pot 200 and a base assembly 100, the base assembly 100 includes a water tank 10, a base 20 and a heating assembly 30, a mounting hole 11 is formed in a bottom wall of the water tank 10, the water tank 10 is mounted on the base 20, the heating assembly 30 is fixedly mounted on the base 20 and mounted on the mounting hole 11, the heating assembly 30 includes a heating plate 31 and a sealing member 32, and the sealing member 32 is surrounded on an outer circumferential surface of the heating plate 31. The water tank 10 is provided with an upward opening, the water tank 10 and the heating plate 31 enclose a heating space for containing water, and the sealing element 32 can ensure the tightness between the water tank 10 and the heating plate 31 and prevent water in the water tank 10 from flowing into the base 20 from a gap between the water tank 10 and the heating assembly 30. During cooking, the heating pan 31 heats the water of the water tank 10, and the heated water transfers heat to the inner pot 200 through the water as a heat transfer medium, thereby heating the food in the inner pot 200.

The sealing member 32 is provided in a ring shape, and the sealing portion 321 and the water blocking portion 322 are each provided in a corresponding ring structure to ensure a sealing effect and a water blocking effect.

As shown in FIGS. 5 and 8, the height difference between the water blocking portion 322 and the bottom wall of the water tank 10 is H, and H is not less than 1.5mm. That is, the highest point of the water blocking portion 322 is at least 1.5mm higher than the lowest point of the bottom wall of the water tank 10, wherein the highest point of the water blocking portion 322 may be any value greater than or equal to 1.5mm higher than the lowest point of the bottom wall of the water tank 10 by 1.5mm, 1.6mm, 1.7mm, 2mm, 3mm, etc. In this way, the separation effect of the water in the water tank 10 can be ensured, the liquid level of the water in the annular space surrounded by the outer wall of the water retaining part 322, the bottom wall and the side wall of the water tank 10 is not lower than 1.5mm, and the water does not flow to the heating plate 31, so that the sufficient water can be ensured to effectively cool the bottom wall of the water tank 10.

As shown in fig. 5, the bottom wall of the water tank 10 may be a plane, the top end of the sealing portion 321 is flush with the plane, and the water blocking portion 322 protrudes from the plane, or the bottom wall of the water tank 10 may be gradually inclined downward from outside to inside as shown, i.e. the connection between the water tank 10 and the sealing member 32 is the lowest point of the bottom wall of the water tank 10, and the top end of the sealing portion 321 is flush with the lowest point of the bottom wall of the water tank 10, because the connection between the water tank 10 and the sealing member 32 is close to the heating plate 31, the liquid level of the water tank 10 in the area close to the heating plate 31 can be ensured, the cooling effect of water on the area of the water tank 10 close to the heating plate 31 can be improved, and meanwhile, the water heating efficiency in the water tank 10 can be prevented from being influenced due to the excessive protrusion of the water blocking portion 322 from the bottom wall of the water tank 10, so as to influence the heating effect on the inner pot 200.

Specifically, the bottom wall of the water tank 10 includes an outer annular wall 12 and an inner annular wall 13 smoothly connected with the outer annular wall, the mounting hole 11 is formed in the inner annular wall 13, the upper surface of the inner annular wall 13 extends obliquely upwards from the edge of the mounting hole 11 towards the outer annular wall 12, the surface of the inner annular wall 13 is lower than the outer annular wall 12, more water is stored at the position of the inner annular wall 13, and because the inner annular wall 13 is closer to the heating plate 31, more water is beneficial to avoiding dry burning of the bottom wall of the water tank 10.

Of course, in other embodiments, after the heating element 30 is mounted in the mounting hole 11, a height difference may be formed between the top end of the sealing portion 321 and the bottom wall of the water tank 10, for example, the top end of the sealing portion 321 is slightly higher or slightly lower than the bottom wall of the water tank 10, so long as the tightness of the sealing portion 321 is ensured, and the top end of the water blocking portion 322 is higher than the bottom wall of the water tank 10, so that water is always remained in the annular space surrounded by the outer wall of the water blocking portion 322, the bottom wall and the side wall of the water tank 10.

As shown in FIG. 8, the thickness L of the water blocking portion 322 satisfies 0.5 mm.ltoreq.L.ltoreq.2 mm. The thickness L of the water blocking portion 322 is a dimension of the water blocking portion 322 along the radial direction of the base assembly 100. The thickness L of the water blocking portion 322 may be any value in the range of 0.5mm to 2mm, such as 0.5mm, 0.6mm, 0.7mm, 1mm, 1.5mm, 2mm, etc. The thickness L of the water retaining portion 322 is more than or equal to 0.5mm, so that the strength of the water retaining portion 322 can be ensured, and the sealing element 32 can be produced conveniently. The thickness L of the water retaining part 322 is less than or equal to 2mm, so that the excessive space of the bottom wall of the water tank 10 can be prevented from being occupied due to the oversized water retaining part 322, and the regular appearance is ensured.

As shown in fig. 5 to 8, a stepped portion 323 is formed between the sealing portion 321 and the water blocking portion 322, the stepped portion 323 being located on a side close to the bottom wall of the water tank 10. When the water level drops to a height corresponding to the highest point of the water blocking portion 322, the water blocking portion 322 divides the water in the water tank 10 into two parts, and the second part is the water in the annular space surrounded by the outer wall of the water blocking portion 322, the step portion 323, the bottom wall and the side wall of the water tank 10. The step 323 makes the diapire of water tank 10 can be covered by water completely, promotes the cooling effect of water to the diapire of water tank 10, further reduces the potential safety hazard.

The sealing portion 321 and the water blocking portion 322 are preferably integrally formed, so that the sealing member 32 is manufactured and processed, and the tightness and reliability of the connection between the sealing portion 321 and the water blocking portion 322 are ensured.

As shown in fig. 3-4, the base assembly 100 further includes a pressure plate 33, the pressure plate 33 being crimped to the seal 32 to seal the water tank 10 from the heating assembly 30.
