[0020] Figure 3 is another schematic cross-sectional structure view of the inner pot of the present utility model. Specific embodiments
[0021] To further elaborate on the technical means and effects adopted by the present application to achieve the predetermined purpose, the following will, in conjunction with the drawings and preferred embodiments, detail the specific embodiments, structures, features and their effects of the present application as follows. In the following description, different "one embodiment" or "embodiment" do not necessarily refer to the same embodiment. In addition, the specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.
[0022] The present utility model relates to a cooking appliance, and its specific products can be rice cookers, electric pressure cookers, electric stew pots and other products.
[0023] The cooking appliance includes a cooking main body, an inner pot and a pot lid. The cooking main body is provided with a heating device, and a receiving groove for placing the inner pot is formed in the cooking main body. The inner pot is placed in the receiving groove to heat and cook the food placed in the inner pot by means of the heating device. The pot lid is covered on the cooking main body, and the mouth of the inner pot is sealed by a sealing ring on the inner side surface of the pot lid.
[0024] The present utility model improves the structure of the inner pot, which not only facilitates the formation of a large-scale circulation of heat and water vapor in the inner pot during the cooking process to improve the heating uniformity and obtain better cooking effects, but also enables the inner pot to be adapted to the sealing rings of the pot lids of conventional electric pressure cookers, so that the inner pot can be commonly used in different cooking appliances, which is beneficial to saving the manufacturing costs of manufacturers.
[0025] Combined with Figures 1 - 3 As shown, the inner pot specifically includes a pot bottom 1 and a pot side wall 2 surrounding the circumferential side of the pot bottom 1. The top of the pot side wall 2 is enclosed to form a mouth; a cooking cavity for holding food materials is jointly enclosed by the pot bottom 1 and the pot side wall 2, and the food materials are put into or taken out of the cooking cavity through the mouth.
[0026] The pot side wall 2 includes, from bottom to top, a connecting wall 21, a circulating wall 22, a necking wall 23 and a sealing wall 24 that are connected in sequence. The mouth of the inner pot is enclosed by the sealing wall 24, and the top end of the sealing wall 24 extends outward along the radial direction of the inner pot to form a pot rim 25.
[0027] As Figure 1 shown is a cross-sectional view of the inner pot. The part between a and b is the pot bottom 1; the part between b and c is the connecting wall 21, the part between c and d is the circulating wall 22, the part between d and e is the necking wall 23, and the part between e and f is the sealing wall 24.
[0028] The connecting wall 21 is the lower section of the pot side wall 2, with the lower end of the connecting wall 21 connected to the periphery of the pot bottom 1, and the upper end of the connecting wall 21 connected to the circulating wall 22, that is, the connecting wall 21 is connected between the pot bottom 1 and the circulating wall 22. The connecting wall 21 can be constructed as a straight wall or an arc wall connected between the pot bottom 1 and the circulating wall 22 as required.
[0029] When the circulating wall 22 is an arc wall, the pot bottom 1 and the circulating wall 22 jointly form a heating bottom of the inner pot that is approximately hemispherical. The cooking host is equipped with a heating device that can heat the inner pot from the pot bottom 1 and the circulating wall 22 from bottom to top, making the heating area of the inner pot larger and the heating more uniform, which is beneficial to improving the cooking effect using the inner pot.
[0030] The circulating wall 22 is connected between the necking wall 23 and the connecting wall 21 and is constructed as an arc wall that protrudes outward relative to the central axis O - O'. The necking wall 23 is arranged above the circulating wall 22 and is indented relative to the circulating wall 22 towards the central axis O - O' of the inner pot.
[0031] Taking cooking rice with a cooking appliance as an example: The outward convex arc structure of the circulating wall 22 provides a guide for the heat and water vapor to diffuse upward, allowing the heat and water vapor to diffuse upward along the circulating wall 22 and outward towards the outer periphery away from the central axis O - O' of the inner pot; when the heat and water vapor reach the position of the necking wall 23, the necking wall 23 guides the heat and water vapor towards the inner side in the direction of the central axis O - O' of the inner pot. The circulating wall 22 and the necking wall 23 cooperate with each other to make it easy for the heat and water vapor to form a large - scale circulation in the pot, which is beneficial to the uniform distribution of heat and moisture in the pot, making the heating of the rice uniform and the gelatinization complete, and enabling the cooked rice to achieve a better taste.
[0032] In addition, the sealing wall 24 is arranged above the necking wall 23 and is constructed as a straight wall along the central axis O - O' direction of the inner pot. Since the sealing wall 24 has a straight wall structure in the central axis direction, the cross - section of the pot lid sealing ring of a conventional electric pressure cooker is approximately T - shaped. The sealing ring includes a radial top edge part limitedly arranged on the inner side surface of the pot lid and a vertical lower edge part integrally formed with the radial top edge and extending vertically downward; when the pot lid is closed on the cooking host, the radial top edge part of the sealing ring is pressed by the pot lid against the pot rim part 25 of the inner pot, and the vertical lower edge part of the sealing ring can be attached to the sealing wall 24 to ensure that the mouth of the inner pot can be sealed when the pot lid is closed. Therefore, setting the sealing wall 24 as a straight wall structure enables the inner pot to be commonly used in different products such as rice cookers and electric pressure cookers, improving the versatility of the inner pot and thus being beneficial to reducing the costs of the manufacturer.
[0033] Especially see Figure 3As shown, due to the outwardly convex arc structure of the circulation wall 22, the maximum diameter D1 of the cooking cavity determined by the inner side wall of the circulation wall 22, and the vertical height H of the inner pot determined from the lowest position of the upper side of the pot bottom 1 to the upper side of the pot rim portion 25. When the relationship between the maximum diameter D1 and the vertical height H of the inner pot satisfies 1.5 ≤ D1 / H ≤ 2.0, the height-diameter ratio of the inner pot can be made more reasonable, and the heat and moisture in the pot can be distributed more optimally up and down, which is beneficial to improving the cooking effect.
[0034] For example, for five different cooking utensils, their D1 / H values are 1.5, 1.6, 1.85, 1.95, and 2.0 respectively.
[0035] In addition, the mouth of the inner pot is enclosed by the inner side wall of the necking wall 23, and the mouth diameter is D2. When the relationship between the maximum diameter D1 and the mouth diameter D2 satisfies 1.04 ≤ D1 / D2 ≤ 1.1, the shape of the inner pot side wall and the size of the mouth indentation can be made more reasonable, and the heat and moisture can more easily form a large circulation within a large range in the pot, which is beneficial to improving the effect of cooking rice.
[0036] For example, for five different cooking utensils, their D1 / D2 values are 1.04, 1.05, 1.06, 1.08, 1.09, and 1.1 respectively.
[0037] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
