In the following description, a detailed structure will be presented for a thorough understanding of embodiments of the invention. It is apparent that the implementation of the embodiments of the present invention is not limited to the specific details familiar to those skilled in the art. The following detailed description of the preferred embodiments of the invention, however, the invention is capable of other embodiments in addition to those detailed.

Fig. 1 shows a schematic perspective view of a cooking appliance 100 according to a preferred embodiment of the present invention, and fig. 3 provides a schematic sectional view of a portion of the cooking appliance 100 according to a preferred embodiment of the present invention. The cooking appliance 100 may be an appliance for heating food or water used in a kitchen such as a pressure cooker or an electric cooker.

As shown in fig. 1 and 3, the cooking appliance 100 includes a pot body 110 and a lid 120, and the lid 120 can be pivotally connected with the pot body 110. The pot body 110 is substantially in the shape of a rounded rectangular parallelepiped and has a receiving portion. The inner pot 111 is configured to be freely put into or taken out of the receiving part to facilitate cleaning of the inner pot 111. The inner pot 111 is used to contain materials to be heated, such as rice, soup, etc., and when the lid 120 covers the pot body 110, a cooking space is defined between the lid 120 and the inner pot 111.

As shown in fig. 3 and 4, a first packing 121 is further mounted on the bottom of the cover 120 in order to ensure the sealing of the cooking space. The first seal ring 121 includes a base portion 121a, a first abutting portion 121b extending substantially vertically downward from the base portion 121a, and a second abutting portion 121c extending downward and inward from the base portion 121a, the second abutting portion 121c being disposed radially outward of the first abutting portion 121 b. In the closed state, both the first contact portion 121b and the second contact portion 121c contact the rim 111a of the inner pot 111, and the cooking space can be sealed there. Specifically, in the present embodiment, the cover body 120 includes a detachable cover 122, and the base portion 121a of the first seal ring 121 is mounted on the detachable cover 122. When the inner pot 111 is provided with a food steamer 130 (to be described in detail later) and the lid 120 is closed to the pot body 110, the first sealing ring 121 presses the food steamer edge of the food steamer 130 downwards.

The cooker body 110 is also provided with a heating device and a control device, and the heating device is used for heating the food in the inner pot 111. The control device is used for controlling the heating device.

A food drawer 130 is also removably disposed in the inner pan 111. Preferably, a horizontally outwardly extending food rim 131 is provided at the mouth of the food steamer 130, and the food steamer rim 131 can be placed on the pot rim 111a so that the food steamer 130 can be placed in the inner pot 111. It should be noted that the directional terms "outer" and "inner" as used herein refer to directions relatively away from the central axis of the cooking appliance 100 and directions relatively close to the central axis of the cooking appliance 100.

The cage body of the cage 130 includes cage side walls 132 and a cage bottom wall 133. The shape of the cage body generally conforms to the shape of the inner pan 111, but the height and radial dimensions of the cage body are less than the inner dimensions of the inner pan 111. Thus, when the cage 130 is placed in the inner pot 111, there is a space between the cage side walls 132 and the side walls of the inner pot 111, and also between the cage bottom wall 133 and the bottom wall of the inner pot 111.

The bottom wall 133 of the cage is provided with a through hole for the passage of liquid, and the cage 130 further comprises a separating barrier 134 extending substantially vertically downwards from the outer periphery of the through hole area of the bottom wall 133 of the cage. In cooking low-sugar rice, rice grains are placed in the food steamer 130, and water is placed in the inner pot 111 such that the water surface is located between the top and bottom ends of the barrier 134 in an unheated state. In a natural state, the chambers on both the inner and outer sides of the baffle cylinder 134 are formed substantially as a communicating vessel. Gas is present in the chamber above the water surface outside the baffle 134 (roughly the cavity between the side wall 132 of the food steamer and the side wall of the inner pot 111). In order to ensure the airtightness of the chamber, a sealing structure is provided at the top end of the chamber.

Specifically, as shown in fig. 3 to 5, the sealing structure includes a second sealing ring 140 disposed between the food drawer rim 131 and the pan rim 111 a. The second seal ring 140 may be made of a flexible material such as rubber, silicone, etc. The second seal ring 140 includes an axially extending portion 141, a radially extending portion 142 extending radially outward with respect to the axially extending portion 141, and a deforming portion 143 extending downward and inward from an end of the radially extending portion 142. The axial extension portion 141 is sleeved on the outer side of the steamer side wall 132 and attached to the outer surface of the steamer side wall 132, and the radial extension portion 142 is attached to the lower surface of the steamer edge 131. Further, the bottom of the radial extension 142 is provided with a groove 142 a. In the closed state, the deformation 143 abuts against the rim 111a of the inner pan 111 under the pressure of the cover and deforms, and at least a portion of the deformation 143 is received in the groove 142a, thereby sealing the cavity between the food steamer 130 and the inner pan 111 at the second sealing ring 140.

According to the scheme, the groove 142a is formed in the bottom of the radial extending part 142 of the second sealing ring 140, and the deformation part 143 is received in the groove 142a in the covering state, so that the occupied space of the second sealing ring 140 in the axial direction can be reduced, the second sealing ring 140 can be prevented from being jacked to the cover body in the covering state, and the hand feeling of covering is guaranteed. Preferably, the wall thickness of the deformation portion 143 ranges from 0.8mm to 1.2mm, which can further reduce the space occupied by the second seal ring 140 in the axial direction.

Preferably, the wall thickness of the axial extension 141 is gradually increased in a direction toward the tip of the axial extension 141. This preferred embodiment prevents the axial extension 141 from deforming, ensuring that the axial extension 141 is firmly engaged on the outside of the cage 130.

Preferably, second seal ring 140 is an integrally formed one-piece member. This scheme facilitates the manufacture of the second seal ring 140 and can secure the firmness of the second seal ring 140.

To further ensure stable mounting of the second sealing ring 140, as shown in fig. 3, the cage side wall 132 further comprises a projection 132a disposed below the axial extension 141. The protrusion 132a protrudes outward and the outer surface thereof is a curved surface. The protrusion 132a is disposed below the axial extension 141 and can support the axial extension 141, so as to ensure that the second sealing ring 140 is not easily dropped from between the food steamer edge 131 and the pan edge 111 a.

When the cover 120 is closed to the pot body 110, the first abutting portion 121b and the second abutting portion 121c of the first sealing ring 121 are compressed in the vertical direction, and a downward pressure is generated on the drawer edge 131. The food steamer edge 131 presses the second sealing ring 140 downwards under the action of pressure, so that the deformation part 143 of the second sealing ring 140 is compressed along the vertical direction, the deformation part 143 is in close contact with the pan edge 111a, and the chamber between the food steamer 130 and the inner pan 111 is sealed at the second sealing ring 140.

Since the chamber between the side wall 132 of the food container and the side wall of the inner pan 111 is sealed at the second sealing ring 140, the gas in the chamber can expand under heat. Specifically, in order to obtain low-sugar rice, when the cooking device 100 starts heating, since the chamber between the food steamer 130 and the inner pan 111 is sealed by the second sealing ring 140, the gas in the chamber expands due to heat and cannot overflow, and a downward force is applied to the water surface outside the barrier cylinder 134, so that the water surface inside the barrier cylinder 134 rises. The water inside the baffle cylinder 134 sinks over the rice grains, and the sugar in the rice grains is dissolved in the water. Then, the heating device stops heating, the air in the chamber between the food steamer 130 and the inner pot 111 contracts, the water surface outside the blocking cylinder 134 rises, the water surface inside the blocking cylinder 134 falls, and water is separated from rice grains. This results in a single heating cycle followed by a similar plurality of heating cycles to complete the cooking. Thus, a cooking mode in which rice grains are intermittently separated from water can be quickly and efficiently realized, thereby cooking low-sugar rice.

According to the cooking utensil of this application can improve the sealed effect between food steamer and the interior pot, can also reduce the occupation space of second sealing washer on axial direction in addition to improve user's closing and covering and feel.
