The cover 120 has a shape substantially corresponding to the pot body 110. As shown in fig. 1, the pot body 110 may be provided with a pivoting part 111 protruding upward. The cover 120 is pivotally connected to the pivot portion 111 about a pivot axis. Specifically, the cover 120 is pivotally connected to the pivoting portion 111 of the pot body 110 by the pivoting shaft 112, and can be freely pivoted about the pivoting axis where the pivoting shaft 112 is located between the closing position and the opening position with respect to the pot body 110, so as to facilitate the closing and opening of the pot body 110. When the cover 120 is covered on the pot body 110, it covers the inner pot, and a cooking space is formed between the inner pot and the cover. The pivot shaft 112 may be provided with a biasing element 113, such as a torsion spring. The biasing element 113 can bias the lid 120 toward the open position for automatic opening.

The damper 130 may be disposed at the rear end of the liner 121. The damping member 130 can be made of an elastic material, for example, an elastic material including rubber such as silicone rubber. In the process of opening the cover 120, the damping member 130 can abut against the pivot portion 111 and be deformed by the extrusion of the pivot portion 111, so as to prevent the cover 120 from moving toward the open position, thereby achieving a smooth opening.

It should be noted that directional terms used herein to describe various components, parts, etc. of the cooking appliance, such as "upper", "lower", "above", "below", "upward", "downward", etc., are relative to the cooking appliance in a horizontally placed and upright state. And "rear end" refers to an end of the cooking appliance that is away from a user when in use.

As shown in fig. 2 and 3, the damping member 130 may have a top surface F131 and a bottom surface F132, and be provided with a mounting groove 131 and a damping surface F133. The mounting groove 131 extends downward from the top surface F131 of the damper 130 and may extend to the bottom surface F132. The notch of the mounting groove 131 faces the side of the center of the cover 120. The damping surface F133 may be connected to the top surface F131 and face the side of the pivot 111. The cover 120 has a bottom wall 122. The damping member 130 is located above the bottom wall 122 and is connected to the bottom wall 122. Specifically, as shown in fig. 4, the inner liner 121 of the cover 120 may be provided with a bottom wall 122 and a positioning portion 123. The positioning portion 123 is located above the bottom wall 122 and spaced apart therefrom. The positioning part 123 may be provided with a male buckle 124. As shown in fig. 1, the positioning part 123 can be located in the installation groove 131, and the damper 130 can be sandwiched between the tab 124 and the bottom wall 122. The top surface F131 of the damper 130 abuts the tab 124, and the bottom surface F132 of the damper 130 abuts the bottom wall 122.

In particular, the damping member 130 may also be provided with a connection groove 132. The coupling groove 132 can communicate with the mounting groove 131, and the notch of the coupling groove 132 faces the center side of the cover body 120. Similarly, the connection groove 132 also extends downward from the top surface F131 of the damping member 130 and may extend to the bottom surface F132. The inner liner 121 may be provided with a connecting wall 125. The mounting portion is connected to the bottom wall 122 by a connecting wall 125. The connecting wall 125 can be located within the connecting slot 132.

Alternatively, the liner 121 may be provided with fixing walls 126 at intervals. The fixed wall 126 is connected to the bottom wall 122. The damper 130 is located between adjacent fixed walls 126. The surfaces of adjacent fixing walls 126 facing each other are provided with fixing buckles 127. The retaining buckle 127 can abut against the top surface F131 of the damper 130 (fig. 1). In the illustrated embodiment, the damping member 130 is provided at one position and corresponds to a central position of the pivot portion 111. Of course, the number of the damping members 130 is not limited, and two or more damping members 130 may be provided at intervals if needed and/or desired.

As shown in fig. 5 and 6, the pot body 110 may include a middle plate 115. The pivoting portion 111 is disposed at the rear end of the middle plate 115 and protrudes upward from the upper surface of the middle plate 115. The pivot portion 111 may be provided with a buffering surface F111. The buffering surface F111 is located on the top of the pivoting portion 111. The relief face F111 may extend in a direction parallel to the pivot axis. Correspondingly, the damping surface F133 may also extend in a direction parallel to the pivot axis. During the process of opening the lid 120, the damping surface F133 of the damping member 130 can abut against the cushioning surface F111 to deform the damping member 130. Therefore, the relative motion between the damping surface F133 and the buffering surface F111 can generate a friction force for preventing the cover body 120 from moving towards the opening position, the damping piece 130 generates deformation at the damping surface F133 to generate a pressure for preventing the cover body 120 from moving towards the opening position, the cover opening action of the cover body 120 can be decelerated under the combined action of the friction force and the pressure, a good cover opening buffering effect is achieved, and cover opening is stable.

The damper 130 of the present embodiment may be further provided with a damper lip 133 protruding from the damper surface F133. The damping lip 133 can be located on the underside of the damping surface F133, specifically the damping surface F133 is disposed at a top corner of the damping member 130, with the damping lip 133 being located below the top corner of the damping member 130. During the opening of the lid 120, the damping lip 133 may abut against the pivot 111 and be pressed by the pivot 111 to be folded downward. The folded damping lip 133 increases the thickness of the damping member 130 in a direction perpendicular to the pivot axis relative to prior damping members 130 that are not provided with the damping lip 133.

In this embodiment, the relative movement between the folded damping lip 133 and the pivot 111 can generate a friction force to resist the movement of the cover 120 toward the open position, and the folded damping lip 133 is pressed by the pivot 111 to generate a pressure force to resist the movement of the cover 120 toward the open position, and the friction force and the pressure force can act together to decelerate the opening and closing of the cover 120, thereby opening the cover smoothly. As the opening angle increases, the degree of deformation of the damping lip 133 gradually increases, which increases the deceleration capacity, resulting in a good opening buffering effect. Compared with the existing damping piece 130, the folded damping lip 133 increases the deformation capacity and thickness of the damping piece 130, so that the damping buffering effect is increased, and when the cover body 120 is located at the final opening position, the damping lip can be completely clamped with the pivoting part 111, and the braking effect is better.

The damping piece 130 that this embodiment provided not only can realize the dual speed reduction to the action of uncapping lid 120, and after utilizing damping face F133 to slow down, damping lip 133 still can uncap the speed reduction, realizes the secondary speed reduction, and the speed reduction effect is better, and uncap cushioning effect is more obvious to effectively avoid the whole machine to uncap the production of beating the phenomenon, more steadily uncap. And because the folded damping lip edge 133 has good deformation capability, the phenomenon that the cover cannot be completely opened can be effectively avoided.

As shown in fig. 6, the pivot portion 111 may be provided with a braking surface F112 facing upward. The braking surface F112 can be connected to the buffering surface F111, and the buffering surface F111 is located at the side of the center of the pot body 110 of the braking surface F112. During the opening of the lid body 120, the braking surface F112 can abut against the folded damper lip 133.

The damping surface F133 may be parallel to the pivot axis. The damping lip 133 may also be parallel to the pivot axis. In this way, in the process of opening the cover 120, the damping member 130 can smoothly cut into the buffer surface F111 and move to the upper side of the pivot portion 111 along the buffer surface F111; and the cover body 120 can keep the stress balance in the uncovering process, so that the uncovering action is smoothly carried out, and the stable uncovering is realized.

The damping lip 133 may be configured in a plate shape, and further, the damping lip 133 is a thin side of the plate shape. The damping member 130 may have two end surfaces F134 opposite to each other and a side surface F135 facing the side where the pivot 111 is located. The side surface F135 is located between the two end surfaces F134 and is connected to the two end surfaces F134. The damping surface F133 is located above a side surface F135 of the damping member 130 and is connected to the side surface F135, and the damping lip 133 can be provided to the side surface F135. Therefore, the damping lip 133 can be more easily close to and abut against the pivoting part 111, the damping and buffering effects are better, and the damping piece 130 is simple in structure and convenient to produce and manufacture.

Specifically, the damping surface F133 extends between two end surfaces F134. In the illustrated embodiment, one damping lip 133 is provided. The one damping lip 133 extends between two end surfaces F134. In an embodiment not shown, the damping lips 133 may be provided at least two spaced apart in a direction parallel to the pivot axis. At least two damping lips 133 are symmetrically disposed with respect to the center of the damping member 130.

The damping lip 133 may be disposed at the center or at a position above the center of the side surface F135 of the damping member 130. Thus, the damping lip 133 can be folded by using the space corresponding to the center of the damping member 130 or below, and the damping lip 133 can be prevented from abutting against the bottom wall 122 of the liner 121 after being folded, so that the damping lip 133 cannot be completely folded to affect the damping and buffering effects.

The damper 130 may be configured as an elongated block member. The damping surface F133 and the damping lip 133 may be disposed along the length of the elongated block member. The length direction of the elongated block member can be parallel to the pivot axis. And the cushioning face F111 extends in a direction parallel to the pivot axis so that the damping face F133 can be brought into uniform abutment with the cushioning face F111 in a direction parallel to the pivot axis, and the degree of deformation of the damping lip 133 in the direction parallel to the pivot axis is substantially equal, which facilitates smooth opening of the lid.

The buffer surface F111 may be configured as an arc surface or a slope surface. The damping surface F133 may also be configured as a curved surface or a sloped surface. Of course, the damping surface F133 may also be a part of the side surface F135 of the damping member 130, i.e., the damping surface F133 is a straight wall surface. In this embodiment, the top surface F131 of the damper 130 is perpendicular to and directly connected to the side surface F135. Braking surface F112 may be configured as a curved surface or a flat surface. Therefore, the damping buffer force can be provided, and the uncovering action is easier to be carried out. When both the relief surface F111 and the braking surface F112 are arc-shaped, the curvature of the relief surface F111 is larger than that of the braking surface F112.

Alternatively, as shown in fig. 3, the bottom corner of the damper 130 may also be provided with a damping surface F133. Therefore, when the damping lip 133 is disposed at the center of the side surface F135, the damping member 130 is a symmetrical member, which makes it possible to mount the damping member 130 to the cover body 120 without distinguishing the front and rear sides of the damping member 130, which is advantageous to improve the working efficiency.

Fig. 7 schematically shows a state of the cover 120 at the closed position. The damping member 130 and the pivoting portion 111 have a certain distance therebetween, the damping surface F133 faces the side of the pivoting portion 111, and the damping lip 133 can just contact the pivoting portion 111 or a small gap exists between the two. The damping lip 133 can be parallel to the pivot axis.

Fig. 8 schematically shows a state where the cover 120 is pivoted to a certain angle but does not reach the open position. Wherein, the damping surface F133 is abutted with the buffer surface F111 and the damping piece 130 is deformed due to the abutment of the damping surface F and the buffer surface F111; the damping lip 133 is deformed downward by the pressing of the pivotal connection portion 111 to be folded.

Fig. 9 schematically shows a state in which the cover 120 is in the open position. Wherein the folded dampening lip 133 is positioned above the braking surface F112 and abuts the braking surface F112.

Referring to fig. 7 to 9, the uncapping process of the present embodiment is as follows:

the cover 120 is pivoted from the covering position to the position where the damping surface F133 is just in contact with the buffering surface F111, and at this time, the damping member 130 is not pressed by the pivot portion 111 and thus is not deformed, and the damping lip 133 is not pressed by the pivot portion 111 and thus is not deformed.

Then, in the process that the cover body 120 continues to pivot towards the opening position but does not reach the opening position, the damping surface F133 and the buffer surface F111 are in extrusion friction, the damping piece 130 is deformed, and friction force and pressure which hinder the cover body 120 from moving towards the opening position are generated, and the opening action of the cover body 120 is decelerated; at the same time, since the damper lip 133 is also deformed downward and folded, the damper lip 133 presses and rubs against the surface of the pivot portion 111, and a frictional force and a pressure force are generated to prevent the cover body 120 from moving toward the open position, and the opening operation of the cover body 120 is further decelerated. In this process, along with the increase of uncapping angle in certain extent, the folding degree of damping lip 133 increases gradually, and this makes the frictional force and the pressure that produce increase gradually, and the deceleration ability increases, plays good uncapping buffering effect.

Finally, during the process that the cover body 120 continues to pivot towards the open position and finally pivots to the open position, the damping surface F133 moves through the buffer surface F111, and the folded damping lip 133 and the braking surface F112 are pressed and rubbed until the folded damping lip 133 cannot be further pressed and is completely clamped with the braking surface F112, at this moment, the cover body 120 stops acting, and the cover opening is completed.

Second embodiment

A cooking appliance according to a second embodiment will be described below with reference to fig. 10 to 16. The cooking appliance of the second embodiment has the same structure and/or construction as the cooking appliance of the first embodiment except for the damper 130. Accordingly, they will not be described and/or illustrated in detail for the sake of brevity.

As shown in fig. 10 and 11, the damping member 130 may be further provided with a slot 234 recessed from a side surface F135 thereof. Further, the opening of the slot 234 faces the side of the pivot 111. The slot 234 can be located at an upper portion of the side surface F135, specifically between the damping surface F133 and the damping lip 133. Preferably, the extension direction of the slot 234 may be parallel to the damping surface F133. Of course, the slot 234 may also extend in a direction that is not parallel to the damping surface F133, i.e., at a small angle, in view of manufacturing tolerances or design requirements. In other words, the extending direction of the slot 234 may be slightly inclined with respect to the damping surface F133.

Specifically, when the damper 130 is configured as an elongated block member, the slot 234 extends along the length of the damper 130. The slot 234 may extend between the two end surfaces F134 of the damping member 130. The damping member 130 is provided with the slot 234, so that the damping member 130 can be deformed at the damping surface F133 more easily, and therefore, during the cover opening process, the damping surface F133 can be cut into the buffering surface F111 of the pivot joint 111 more easily and move relative to the buffering surface F111.

In the present embodiment, the damping lip 133 protrudes from the side surface F135 of the damping member 130 facing the side of the pivot portion 111. in other words, the damping lip 133 protrudes toward the side of the pivot portion 111. The projecting direction of the damping lip 133 faces the pivot axis. Preferably, the projecting direction may be perpendicular to the pivot axis. Such that the damping lip 133 is deformed to a substantially equal degree in a direction parallel to the pivot axis, which facilitates smooth opening of the lid. The damping lip 133 has a thickness T and an extension L in the projecting direction. The dampening and cushioning effect produced by the dampening lip 133 can be adjusted by adjusting the thickness T and extension L of the dampening lip 133. The thickness T is the maximum thickness of the damping lip 133.

Considering that the greater the thickness T of the damping lip 133, the smaller the extension L, the more difficult the damping lip 133 is to fold. Thus, in order to enable the damper lip 133 to be folded, the following arrangement may be made:

when L >2T, the thickness of the damping lip 133 may be constant in the direction of projection, as shown in fig. 11, i.e., the cross-sectional shape of the damping lip 133 is rectangular, or the thickness of the damping lip 133 may gradually decrease in the direction of projection, as shown in fig. 12 and 13, i.e., the cross-sectional shape of the damping lip 133 is trapezoidal or triangular.

When L is less than or equal to 2T, the thickness of the damping lip 133 is gradually reduced along the protruding direction, that is, the cross-sectional shape of the damping lip 133 is trapezoidal or triangular.

By way of example, the damping lip 133 may have a distance D (FIG. 14) to the bottom wall 122, and the damping lip 133 may have an extension L greater than 2mm and less than the distance D between the damping lip 133 and the bottom wall 122. For example, the extension L may be 2.5mm, 3mm, 4mm, 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, or the like. The thickness T of the damping lip 133 is less than or equal to 3 mm. For example, the thickness T may be 1.5mm, 1.6mm, 1.8mm, 2.0mm, 2.2mm, 2.4mm, 2.6mm, 2.8mm, 3.0mm, and the like. Thus, the damping lip 133 can achieve a better damping and cushioning effect.

Fig. 14 schematically shows a state where the lid body 120 is at the closed position. The damping member 130 and the pivoting portion 111 have a certain distance therebetween, the damping surface F133 faces the side of the pivoting portion 111, and the damping lip 133 can just contact the pivoting portion 111 or a small gap exists between the two. The slot 234 is in an uncompressed original state.

Fig. 15 schematically shows a state where the cover body 120 is pivoted to a certain angle but does not reach the open position. The damping surface F133 is abutted against the buffering surface F111, the damping piece 130 deforms due to the abutment of the damping surface F and the buffering surface F111, and meanwhile, the damping piece 130 deforms towards the position of the slot 234; the damping lip 133 is deformed downward by the pressing of the pivotal connection portion 111 to be folded.

Fig. 9 schematically shows a state in which the cover 120 is in the open position. With the folded dampening lip 133 positioned above and abutting braking surface F112 and the slot 234 in an uncompressed original state.

Referring to fig. 14 to 16, the uncapping process of the present embodiment is as follows:

the cover 120 is pivoted from the covering position to the position where the damping surface F133 is just in contact with the buffering surface F111, and at this time, the damping member 130 is not pressed by the pivot portion 111 and thus is not deformed, and the damping lip 133 is not pressed by the pivot portion 111 and thus is not deformed.

Then, during the process that the cover 120 continues to pivot towards the open position but does not reach the open position, the damping surface F133 presses and rubs against the buffer surface F111, the damping member 130 deforms towards the position of the slot 234 due to the slot 234, and friction and pressure are generated to hinder the cover 120 from moving towards the open position, and the cover opening action of the cover 120 is decelerated. In this process, as the opening angle increases within a certain range, the deformation of the damping member 130 toward the position of the slot 234 increases, and the deformation decreases after increasing to a certain amount. At the same time, since the damper lip 133 is also deformed downward and folded, the damper lip 133 presses and rubs against the surface of the pivot portion 111, and a frictional force and a pressure force are generated to prevent the cover body 120 from moving toward the open position, and the opening operation of the cover body 120 is further decelerated. In this process, along with the increase of uncapping angle in certain extent, the folding degree of damping lip 133 increases gradually, and this makes the frictional force and the pressure that produce increase gradually, and the deceleration ability increases, plays good uncapping buffering effect.

Finally, as the cover 120 continues to pivot toward and eventually to the open position, the damping surface F133 moves past the braking surface F112, then the slot 234 moves past the braking surface F112, and then the folded damping lip 133 presses against the braking surface F112 until the folded damping lip 133 cannot be pressed further and completely engages the braking surface F112, at which point the cover 120 stops and the opening is complete.
