[0120] AsFigure 1 and Figure 2 As shown in FIGS. 1 and 2, the cooking appliance 100 according to the specific embodiment of the present application mainly comprises a cover body 10 and a pot body 90. The pot body 90 is substantially a rectangular cuboid with rounded corners, and has a cooking container receiving portion in a cylindrical shape, in which a cooking container 91 can be freely put in or taken out for the convenience of cleaning the cooking container 91. The cooking container 91 has a circular opening at the top for containing materials to be heated, such as rice, soup, etc. A flange 92 is provided at the opening of the cooking container 91 and is bent outward. For example, the flange 92 has a horizontal upper surface with a radial dimension of 5mm to 25mm of the cooking container 91. The cover body 10 is substantially a rectangular cuboid with rounded corners and substantially corresponds to the shape of the pot body 90. The cover body 10 is pivotally connected to the pot body 90 in a hingable manner for covering the pot body 90. When the cover body 10 is covered on the pot body 90, a cooking space is formed between the cover body 10 and the cooking container 91.

[0121] The cover body 10 comprises a cover 11 and a detachable cover assembly 30 which is detachably connected to the cover 11. One side of the cover 11 along the length direction is a connecting end which is pivotally connected to the pot body 90, and the opposite side is a pivoting end for opening and closing the cover.

[0122] As shown in FIGS. 3 and 4, the detachable cover assembly 30 comprises a cover plate 31 and a first sealing member 50. The cover plate 31 is installed to the lower side of the cover 11 and is movable up and down relative to the cover 11. The first sealing member 50 is installed to the cover plate 31. The lower end of the first sealing member 50 protrudes downward from the lowest part of the lower surface of the cover plate 31. When the cover body 10 covers the pot body 90, the lower end (lower surface) of the first sealing member 50 contacts the opening of the cooking container 91, for example, the upper surface of the flange 92, to seal between the cover body 10 and the cooking container 91. With the downward movement of the cover plate 31, the first sealing member 50 is pressed between the cover plate 31 and the flange 92. Figure 2 and Figure 3 The cover body 10 further comprises at least one acting member 60 which is provided between the cover plate 31 and the cover 11, and is configured to apply a downward pushing force to the cover plate 31 so that the first sealing member 50 is pressed against the opening of the cooking container 91 to overcome the problem of poor fit of the first sealing member 50 to the opening of the cooking container 91 due to the tolerance accumulation of the sizes and shapes of the cover plate, the pot body, the hinge structure, the inner pot, etc., and to ensure the sealing reliability.

[0123] The cover body 10 further comprises at least one acting member 60 which is provided between the cover plate 31 and the cover 11, and is configured to apply a downward pushing force to the cover plate 31 so that the first sealing member 50 is pressed against the opening of the cooking container 91 to overcome the problem of poor fit of the first sealing member 50 to the opening of the cooking container 91 due to the tolerance accumulation of the sizes and shapes of the cover plate, the pot body, the hinge structure, the inner pot, etc., and to ensure the sealing reliability.

[0124] It should be noted that "up" and "down" in the present application refer to the corresponding directions in the state that the cooking appliance 100 is normally placed and the cover body 10 is covered to the pot body 90. The acting member 60 can be arranged on the cover 11 or the cover plate 31, or partially arranged on the cover 11 and partially arranged on the cover plate 31.

[0125] In the first embodiment, the acting member 60 comprises an elastic member, and the upper and lower ends of the elastic member act on the cover 11 and the cover plate 31, respectively.

[0126] In the first embodiment, as shown in Figure 2 to Figure 5 the elastic member is a spring 61 configured to deform in the up-down direction. The acting member 60 is arranged on the cover 11, and further comprises a receiving space 60A for accommodating the spring 61, the bottom wall 63A of the receiving space 60A is movable up and down relative to the top wall 62A of the receiving space 60A, the upper end of the spring 61 is arranged to abut the lower side of the top wall 62A of the receiving space 60A, and the lower end of the spring 61 is arranged to abut the upper side of the bottom wall 63A of the receiving space 60A. Thus, the spring 61 is subjected to the downward force of the cover 11, and the bottom wall 63A exerts a downward pushing force on the cover plate 31 under the elastic force of the spring 61, so that the first sealing member 50 is pressed against the opening of the cooking container 91.

[0127] Optionally, the top wall 62A of the receiving space 60A is provided with a downwardly protruding guide column 62D, and the upper end of the spring 61 is arranged around the guide column 62D and extends and retracts along the guide column 62D. Optionally, the bottom wall 63A of the receiving space 60A is provided with an upwardly protruding guide column 63D, and the lower end of the spring 61 is arranged around the guide column 63D and extends and retracts along the guide column 63D. Thus, the spring 61 is stably installed, and the movement process is reliable.

[0128] Optionally, the bottom wall 63A of the receiving space 60A is movable up and down relative to the top wall 62A of the receiving space 60A within a distance range of not more than 5 mm. The up-down movement distance of the bottom wall 63A relative to the top wall 62A of the receiving space 60A, i.e. the up-down movement distance of the cover plate 31 relative to the cover 11, is within 5 mm, which is sufficient to fill the gap caused by the tolerance and ensure the reliability of the sealing.

[0129] Optionally, the acting member 60 comprises a first accommodating groove 62 and a second accommodating groove 63. The first accommodating groove 62 is arranged on the cover 11, and the groove opening of the first accommodating groove 62 faces downward. The groove opening of the second accommodating groove 63 faces upward, the side wall 63B of the second accommodating groove 63 is connected to the side wall 62B of the first accommodating groove 62 to jointly enclose the accommodating space 60A with the first accommodating groove 62, and the side wall 63B of the second accommodating groove 63 is movable up and down relative to the side wall 62B of the first accommodating groove 62. The groove bottom of the first accommodating groove 62 forms the top wall 62A of the accommodating space 60A, and the groove bottom of the second accommodating groove 63 forms the bottom wall 63A of the accommodating space 60A.

[0130] Specifically, the side wall 62B of the first accommodating groove 62 is located at the outer periphery of the side wall 63B of the second accommodating groove 63, and meanwhile, the inner surface of the side wall 62B of the first accommodating groove 62 is provided with a first inner flange 62C extending radially inward, and the outer surface of the side wall 63B of the second accommodating groove 63 is provided with a second outer flange 63C extending radially outward, and the second outer flange 63C is located above the first inner flange 62C. Thus, by limiting the downward movement of the second outer flange 63C by the first inner flange 62C, the downward movement distance of the bottom wall 63A relative to the top wall 62A can be limited, and the bottom wall 63A will not fall off.

[0131] In the illustrated embodiment, in order to facilitate the installation of the acting member 60, the groove bottom and the side wall of the first accommodating groove 62 are arranged to be detachably connected. Figure 4 The side wall 62B of the first accommodating groove is not shown in the figure. The top wall 62A can be provided with a flange extending downward to be positioned in the connection with the side wall 62B of the first accommodating groove 62. The side wall 62B of the first accommodating groove 62 is, for example, a cylinder formed in the cover 11, and can also be detachably connected with the cover 11. When installing the acting member 60, the second accommodating groove 63 is first placed in the cylinder, then the spring 61 is placed in the accommodating space 60A, and finally the top wall 62A is capped.

[0132] Alternatively, in an embodiment not shown in the present application, the side wall 62B of the first accommodating groove 62 is located at the inner periphery of the side wall 63B of the second accommodating groove 63, the outer surface of the side wall 62B of the first accommodating groove 62 is provided with a first outer flange extending radially outward, the inner surface of the side wall 63B of the second accommodating groove 63 is provided with a second inner flange extending radially inward, and the second inner flange is located above the first outer flange. Thus, by limiting the downward movement of the second outer flange 63C by the first inner flange 62C, the downward movement distance of the bottom wall 63A relative to the top wall 62A can be limited, and the bottom wall 63A will not fall off. In such an embodiment, in order to facilitate the installation of the acting member 60, the groove bottom and the side wall of the second accommodating groove 63 are arranged to be detachably connected, or the second inner flange and the side wall 63B of the second accommodating groove are arranged to be detachably connected.

[0133] Optionally, asFigure 6 As shown, the cover plate 31 is made of ferromagnetic material, and the bottom wall 63A of the accommodating space 60A is provided with a magnet 64. Specifically, the magnet 64 can be arranged on the upper side of the bottom wall 63A (i.e. inside the accommodating space 60A), or arranged on the lower side of the bottom wall 63A (i.e. outside the accommodating space 60A), or the magnet 64 is the bottom wall 63A, or embedded in the bottom wall 63A. Thus, the magnet 64 can attract the cover plate 31 to the bottom wall 63A, so that the cover plate 31 moves up and down with the bottom wall 63A, and the cover plate 31 is simple to install.

[0134] In the second embodiment, as shown in Figure 7 and Figure 8 As shown, the elastic member is a second sealing ring 67, the upper end of the second sealing ring 67 is used to contact the cover 11, and the lower end of the second sealing ring 67 is used to contact the cover plate 31. Thus, the second sealing ring 67 can apply a downward force to the cover plate 31, so that the first sealing member 50 is pressed against the opening of the cooking container 91, and the sealing reliability between the cover plate 31 and the cooking container 91 is ensured.

[0135] For example, the second sealing ring 67 can be a glass plate sealing ring. In such an embodiment, the cover 11 includes an inner cover 19, a far-infrared heating device (not shown in the figure), and a glass plate 20. The far-infrared heating device is arranged on the inner cover 19 and is used to emit far-infrared rays. The glass plate 20 is arranged on the inner cover 19 and is located below the far-infrared heating device. The far-infrared rays can be radiated into the cooking space through the glass plate 20. The second sealing ring 67 is connected to the outer peripheral edge of the glass plate 20 and is used for sealing between the glass plate 20 and the inner cover 19. The second sealing ring 67 protrudes downward from the glass plate 20 to contact the cover plate 31 and apply a downward force to the cover plate 31. The part of the second sealing ring 67 that protrudes downward from the glass plate 20 can be arranged in a bent structure to apply an elastic force to the cover plate 31. Of course, the second sealing ring 67 can also be other forms of sealing rings.

[0136] In the third embodiment, as shown in Figure 9 The acting member 60 includes a first magnet 65 arranged on the cover 11 and a second magnet 66 arranged on the cover plate 31, and the first magnet 65 and the second magnet 66 repel each other. Thus, the cover plate 31 is subjected to a downward force by the second magnet 66, so that the first sealing member 50 is pressed against the opening of the cooking container 91. At the same time, the acting member 60 is simple in design and easy to install.

[0137] Optionally, the cover 10 can include an acting member 60 above the geometric center of the cover plate 31. The cover 10 can also include a plurality of acting members 60 spaced apart from each other. For example, two acting members 60 are arranged on the same diameter of the circular cover plate 31 and have equal distance to the center of the circle. For another example, three acting members 60 are arranged at the three vertices of an equilateral triangle, and the center of the triangle coincides with the geometric center of the cover plate 31. The plurality of acting members 60 can generate a larger pushing force on the cover plate 31, and the acting force on the cover plate 31 can make the cover plate 31 translate downward without deflection.

[0138] Optionally, the cover plate 31 is detachably connected to the cover liner 11. As shown, a movable buckle assembly is arranged on one side of the cover liner 11 along the length direction (e.g. on one side of the pivoting end of the cover liner 11) for detachable connection with the edge portion of the cover plate 31. Specifically, the movable buckle assembly includes a movable buckle 14 arranged on the cover liner 11, which can be engaged with the pot buckle 13 arranged on the pot body 90 when the cover 10 is closed to the pot body 90 after the cover plate 31 is installed to the cover liner 11. Meanwhile, the movable buckle 14 has an outward convex platform 141 on the side facing the cover plate 31, which can have an upward supporting effect on the cover plate 31 after the cover plate 31 is installed to the cover liner 11. Figure 3

[0139] Preferably, the movable buckle assembly further includes a spring 15, one end of which abuts the movable buckle 14 and the other end of which abuts the cover liner 11. The spring 15 is used to deviate the movable buckle 14 from the position engaged with the pot buckle 13, e.g. on the inner side of the engaged position, i.e. the side closer to the center of the cover 10 relative to the engaged position, in the state that the cover 10 is not installed with the cover plate 31. Thus, when the user forgets to install the cover plate 31, the cover 10 will not be engaged with the pot body 90 after being closed to the pot body 90, so as to remind the user to install the cover plate 31. Further, one end of the spring 15 abuts the outer side of the movable buckle 14, which is provided with a guide protrusion 142, and the one end of the spring 15 is sleeved on the outer periphery of the guide protrusion 142. The guide protrusion 142 has a limiting and guiding effect on the spring 15. Here, the outer side refers to the side away from the center of the cover 10.

[0140] Optionally, in an embodiment, as shown in Figure 1 ​As shown, the other side of the lining cover 11 along the length direction is provided with two width direction spaced apart accommodating grooves 16 for accommodating the edge portion of the cover plate 31. Meanwhile, the diameter of the cover plate 31 is greater than the outer diameter of the opening of the cooking container 91, so that the outer convex platform 141 of the movable buckle 14 can support the cover plate 31, and the movable buckle 14 does not interfere with the cooking container 91. Thus, the two accommodating grooves 16 and the movable buckle 14 are located at three different positions along the circumference of the cover plate 31, and jointly support the cover plate 31 upward in the closed state of the cover body 10.

[0141] When installing the cover plate 31, the cover plate 31 is first placed obliquely into the two accommodating grooves 16, at which time the cover plate 31 is supported and limited by the opening edges of the two accommodating grooves 16, and is kept in the oblique state as shown in the figure. Figure 10 When the cover plate 31 is pushed towards the lining cover 11, the edge portion of the cover plate 31 pushes the movable buckle 14 to avoid until it is installed in place, that is, the edge portion of the cover plate 31 enters the position of the outer convex platform 141 on the side facing the lining cover 11. The outer convex platform 141 of the movable buckle 14 and the two accommodating grooves 16 support the edge portion of the cover plate 31. When the cover body 10 is in the open state, the cover plate 31 is removed, the movable buckle 14 is actuated to release one end of the cover plate 31, and the cover plate 31 is inclined under the action of gravity until it is stopped by the opening edges of the two accommodating grooves 16, at which time the cover plate 31 can be directly taken out.

[0142] Alternatively, in another embodiment, as shown in Figure 1 , Figure 11 and Figure 12 , the lining cover 11 is provided with a lining cover steam passage 17 for discharging steam, and the middle portion of the cover plate 31 is provided with a cover plate steam passage 38, the lining cover steam passage 17 is used for sealingly sleeving the outer circumference of the cover plate steam passage 38. The cover plate steam passage 38 can be used for positioning when the cover plate 31 is installed to the lining cover 11. Further, the lining cover steam passage 17 is provided with an inner convex portion 171, which is convex from the inner wall of the lining cover steam passage 17 to the central axis of the lining cover steam passage 17. The inner convex portion 171 has elasticity, for example, is at least part of a sealing ring made of silica gel. The inner convex portion 171 can have an upward supporting effect on the cover plate 31 through the cover plate steam passage 38 after the lining cover steam passage 17 is sleeved with the cover plate steam passage 38, thereby supporting the cover plate 31 together with the movable buckle 14 at the two positions.

[0143] Alternatively, as shown in Figure 1 and Figure 2As shown, the liner 11 is provided with a temperature sensor 18 for detecting the temperature of the top of the cooking space. The cover plate 31 is provided with a temperature sensor aperture 39 for the temperature sensor 18 to pass through. The temperature sensor aperture 39 can be used for positioning when the cover plate 31 is installed, i.e. the cover plate 31 is positioned relative to the liner 11 by the alignment of the temperature sensor aperture 39 with the temperature sensor 18.
