Generally, as shown in fig. 1, a cooking appliance 100 such as an electric rice cooker includes a pot body 110 and a cover 120. The pot body 110 is substantially in a rounded rectangular parallelepiped shape and has a cylindrical inner pot receiving part. The inner pan 130 may be fixedly disposed at the inner pan receiving portion, or may be freely put into or taken out of the inner pan receiving portion, so as to facilitate cleaning of the inner pan 130. The inner pot 130 is generally made of a metal material and has a circular opening on an upper surface for containing a material to be heated, such as rice, soup, etc. The pot body 110 includes therein heating means for heating the inner pot 130 to heat the inner pot 130. It can be understood that the cooking appliance 100 according to the present invention may be an electric cooker, an electric pressure cooker or other cooking appliances 100, and the cooking appliance 100 may have various functions such as cooking porridge, etc. in addition to the function of cooking rice.

The cover 120 has a shape substantially corresponding to the pot body 110, and is substantially in the shape of a rounded rectangular parallelepiped, is pivotally connected to the pot body 110 by a pivot shaft 142, and can freely pivot about the pivot axis where the pivot shaft 142 is located between a covering position (see fig. 2) and an opening position (see fig. 4) with respect to the pot body 110, so as to facilitate the covering and opening of the pot body 110. When the cover 120 is covered on the pot body 110, it covers the inner pot 130, and a cooking space is formed between the inner pot 130. The lid 120 also typically has a gasket, which may be made of, for example, a rubber material, disposed between the lid 120 and the inner pot 130 for sealing the cooking space when the lid 120 is in a closed position.

It should be noted that directional terms used herein in describing the components in the cooking appliance 100 and the positional relationship thereof, such as "above", "below", "upper side", "upward", "downward", and the like, are relative to a state where the cooking appliance 100 is in a horizontal state and the lid 120 is covered on the pot body 110. Directional terms "inner" and "outer" if not otherwise defined, it is understood that "inner" refers to a side closer to the center of the cooking appliance and "outer" refers to a side farther from the center of the cooking appliance.

Specifically, the pot body 110 has a pivoting part 111 connected to the cover 120. The pivoting part 111 extends vertically and protrudes from the top of the inner pot 130. The cover body 120 includes an inner liner 121, and a cover (not shown) is provided on the upper or outer side of the inner liner 121. Liner 121 has a liner opening for receiving pivot 111. The pivot shaft 142 is disposed at the opening of the liner and is limited to the pivot portion 111, and two ends thereof extend into the liner 121.

In the illustrated embodiment, as shown in fig. 1 and 2, the cooking appliance 100 further includes a biasing member 141 to bias the cover 120 in the opening direction. The biasing member 141 is provided between the cover 120 and the pot body 110, the biasing member 141 is fitted to the pivot shaft 142, and one end of the biasing member 141 extends and is fitted into the cover 120 and the other end of the biasing member 141 opposite to the one end extends and is fitted into the pot body 110. The biasing member 141 can provide a biasing force of the cover 120 in the opening direction so that the cover 120 can be automatically opened from the covering position to the opening position. In an embodiment not shown, the biasing member 141 may not be provided, and the cover may be opened manually by a user.

The biasing member 141 is provided between the liner 121 and the cover, and has one end mounted to the upper side of the liner 121 and the other end extending substantially downward and mounted into the pivot 111. The illustrated embodiment exemplarily shows that the biasing member 141 is a torsion spring.

The pot body 110 may be provided with a damping wall 112 extending in a vertical direction. The damping wall 112 is located at the pivot portion 111. The cover 120 is provided with a damping fin 150 engaged with the damping wall 112. During the opening of the lid body 120, the damper 150 can abut against the damper wall 112, the damper 150 is disposed outside the damper wall 112 in a direction parallel to the pivot axis, and a frictional resistance force in the direction opposite to the opening direction is generated between the damper 150 and the damper wall 112. In other words, the damping plate 150 and the damping wall 112 are pressed against each other, so that the damping plate 150 is deformed in a direction away from the damping wall 112. Therefore, in the process of opening the lid 120, the damping fin 150 can abut against the damping wall 112 and deform, so that a frictional resistance is generated between the damping fin 150 and the damping wall 112, and the frictional resistance is opposite to the opening direction, thereby reducing the acting force for opening the lid 120 in the opening direction, stabilizing the automatic opening process of the lid, and avoiding the shaking of the cooking utensil.

In the illustrated embodiment, the force that opens the cover 120 includes the biasing force of the biasing member 141. The frictional resistance is a reaction force of the biasing force provided by the biasing member 141, i.e. the direction of the frictional resistance is opposite to the direction of the biasing force, so that the acting force of the biasing member 141 on the lid 120 in the process of opening the lid 120 can be reduced, and the process of opening the lid 120 is smooth.

The cover 120 may also be provided with an elastic member 160. The elastic member 160 is disposed at a side of the damping plate 150, particularly, a side of the damping plate 150 facing away from the damping wall 112. The elastic member 160 abuts the damper sheet 150. When the cover 120 is opened, the damper 150 is deformed to press the elastic member 160, and the elastic member 160 is pressed to apply an elastic force to the damper 150. It is understood that the damper 150 in this embodiment is an elastically deformable member. The frictional resistance is less than the biasing force. In this embodiment, the elastic member 160 may always generate an elastic force toward the damper sheet 150, and the elastic force may be increased when being pressed by the damper sheet 150. Alternatively, in another embodiment, the elastic member 160 may generate an elastic force when being pressed by the damping fin 150.

As shown in fig. 2 and 3, when the lid 120 is in the closed position, the illustrated closed position is a substantially horizontal position, and the damper 150 is spaced apart from the damper wall 112 of the pot body 110. When the cover 120 is opened to a certain angle, one end of the damper 150 can abut against the damper wall 112. During the pivoting of the cover 120 from this angular position to the open position (see fig. 4), which is shown in a substantially vertical position (i.e., the cover 120 is substantially perpendicular to the pot body 110), the above-mentioned frictional resistance between the damping fins 150 and the damping wall 112 is generated against the biasing force. In the illustrated embodiment, the surfaces of the damper 150 and the damper wall 112 facing each other are flat surfaces, and the two surfaces abut against each other.

Further, in the illustrated embodiment, the damping wall 112 may be located outside the pivoting part 111 in the direction of the pivoting shaft 142. And the damper 150 is disposed inside the elastic member 160 in a direction parallel to the pivot shaft 142. Here, "outer side" refers to a side away from the center of the cooking appliance 100 in the direction of the pivot axis 142, and "inner side" refers to a side close to the center of the cooking appliance 100 in the direction of the pivot axis 142. Alternatively, the damping sheet 150 extends vertically and is slightly inclined toward the damping wall 112 when the cover 120 is in the closed position. The angle between the surfaces of the damping fin 150 and the damping wall 112 facing each other is acute. It can be understood that the included angle is small, and the automatic cover opening process of the cover body cannot be influenced. So that the deformation of the damping fin may be gradually increased during the opening of the cover 120 to gradually increase the frictional resistance. For example, the damping wall 112 (specifically, the outer surface of the damping wall 112 facing away from the pivot joint 111) may be perpendicular to the pivot axis, and in this embodiment, the angle between the damping plate 150 and the pivot axis may be smaller than 90 degrees.

Although the illustrated embodiment shows that the damping wall 112 is disposed at one side of the pivotal connection part 111, the damping fin 150 is disposed at one side of the damping wall 112. However, in an embodiment not shown, the damping wall 112 may include two damping walls, respectively disposed at both sides of the pivot portion 111. The damping fins 150 may include two, which are respectively disposed at both sides of the damping wall 112, that is, the damping fins 150 and the damping wall 112 correspond one to one. Alternatively, the damping wall 112 may be made of a plastic material, and the damping wall 112 may be molded as a single piece with the pivot 111.

Further, as shown in fig. 3, liner 121 may be provided with ribs 122 extending upwardly. The elastic member 160 is disposed between the rib plate 122 and the damper 150. The elastic member 160 may be limited in the gap between the rib plate 122 and the damper pad 150, and clamped by the rib plate 122 and the damper pad 150. Specifically, the rib 122 may extend along a length direction of the cooking appliance 100 (specifically, a direction perpendicular to the direction of the pivot axis 142). Ribs 122 are spaced from damping wall 112. The damping plate 150 and the elastic member 160 may be located between the rib plate 122 and the damping wall 112 when the cover body 120 is pivoted from a certain angular position to an open position (refer to fig. 5).

As shown in fig. 6, liner 121 may also be provided with a barrier rib 123 extending from rib 122. The elastic member 160 is caught between the blocking ribs 123. Specifically, the blocking ribs 123 extend toward one side of the damper 150 and are vertically arranged. The elastic member 160 may be limited between two vertical blocking ribs 123 (refer to fig. 3). The elastic member 160 may be an elastic block. Alternatively, the elastic member 160 may be a silicone block or a spring. The elastic member 160 may have a size corresponding to that of the damping plate 150, so that the elastic member 160 may maintain contact friction between the damping plate 150 and the damping wall 112 in case the damping plate 150 is deformed due to long-term friction, thereby reducing aging effects.

As shown in fig. 7, both ends of the damper 150 may have bent flanges 151, and in particular, both ends of the damper 150 in a direction perpendicular to the vertical direction may have flanges 151. The burring 151 extends vertically and is bent toward one side of the elastic member 160 (in the mounted state of the damper 150). The burring 151 has a smooth surface so that both ends of the damper 150 do not scrape the surface of the damper wall 112 to damage the damper wall 112 when the damper 150 abuts against the damper wall 112. Optionally, the elastic member 160 is trapped between the two cuffs 151. A top opening 152 may be provided between the top of the flange 151 and the top of the damper 150 to facilitate deformation of the damper 150.

Further, the damper 150 may include a channel-shaped body 153 opening downward and a mounting portion 154 extending from the channel-shaped body 153. Rib 122 may be received into channel-shaped body 153 from below (at the opening). During installation of damper 150, channel-shaped body 153 may be moved downward from above rib 122, and rib 122 passes through the opening of channel-shaped body 153 and is received in channel-shaped body 153. Mounting portion 154 may be coupled to liner 121. Alternatively, the mounting portion 154 extends horizontally (in a state where the damper 150 is placed vertically as shown in fig. 3) and may be provided with a through hole 155. The inner liner 121 may be provided with screw posts 124 (see fig. 6) located outside the webs 122, in particular the screw posts 124 located on the side of the webs 122 facing away from the resilient member 160. The screw post 124 has a screw hole. The damper 150 may be mounted to the liner 121 by fasteners, such as screws, extending through the through holes 155 into the screw posts 124. Of course, in an embodiment not shown, liner 121 may be provided with a snap structure to snap damper 150 to liner 121.

Specifically, the channel-shaped body 153 includes a first wall 156 and a second wall 157 that is substantially parallel to the first wall 156. The elastic member 160 is disposed between the first wall 156 and the rib 122, the first wall 156 can be deformed by abutting against the damping wall 112 during the opening process of the cover 120, the elastic member 160 can be pressed after the first wall 156 is deformed, and the elastic force generated by the elastic member 160 can press the first wall 156 against the damping wall 112 to generate a frictional resistance. The mounting portion 154 extends from the second wall 157, and in particular, from a lower portion of the second wall 157. The first wall 156 has bent flanges 151 at both ends. An opening may be provided between the top of the flange 151 and the top of the first wall 156. In the illustrated embodiment, the first wall 156 is longer than the vertical dimension of the second wall 157. The first wall 156 has a size generally corresponding to the size of the resilient member 160.

Optionally, the damping fin 150 is a metal dome. Preferably, the damping plate 150 is a metal elastic plate. The damper 150 may be a unitary piece formed by bending a metal sheet. Therefore, the damping fins 150 are disposed between the elastic members 160, and in the embodiment where the elastic members 160 are silica gel blocks, the silica gel blocks can be prevented from directly contacting the damping wall 112 due to the damping fins 150, so that the silica gel blocks are not prone to dust falling due to long-term abrasion.

In embodiments not shown, a damping wall may be provided inside the pivot joint if needed and/or desired. The damping fin may be disposed inside the damping wall. Specifically, the damping wall, the damping fin, the elastic member and the rib plate can be arranged in a straight line in sequence from outside to inside along a direction perpendicular to the pivot shaft.
