[0065] First embodiment

[0066] Reference Figure 1 and Figure 2 The first embodiment of the present application provides a cooking appliance 1 including a cover 20 and a pot body 10. The cover 20 has a shape substantially corresponding to that of the pot body 10. The cover 20 is arranged on the pot body 10 in a manner that can be opened and closed. The cover 20 can be, for example, pivotally connected to the pot body 10 by a pivot shaft, and can be freely pivoted about a pivot axis AX0 where the pivot shaft is located, between a closed position and an open position relative to the pot body 10, to facilitate closing and opening of the pot body 10. The cooking appliance 1 further has a resilient member 30 connected with the pot body 10 and the cover 20, the resilient member 30 being configured to apply an elastic force to the cover 20 such that the cover 20 has a tendency to open, so as to enable the cover 20 to be automatically opened. Exemplarily, the resilient member 30 can be configured as a torsion spring, two arms of the torsion spring being connected to the pot body 10 and the cover 20 respectively.

[0067] The pot body 10 includes an inner pot 13, and has a receiving portion in a cylindrical shape. The inner pot 13 can be freely put into or taken out of the receiving portion, to facilitate cleaning of the inner pot 13. The inner pot 13 is usually made of a metal material and has a circular opening on an upper surface, for containing materials to be heated, such as rice, soup, etc. The pot body 10 further has a middle plate 11, the middle plate 11 being provided with an opening corresponding to the receiving portion, to allow the inner pot 13 to be put in or taken out.

[0068] The heating device is arranged below the inner pot 13. The heating device can be a device such as a coil plate.

[0069] When the cover body 20 is closed on the pot body 10, it covers the inner pot 13, and a cooking space is formed between the cover body 20 and the inner pot 13. The cover body 20 comprises a face cover 21, an inner liner 22, and a detachable cover (not shown). The face cover 21 is arranged above the inner liner 22, and the detachable cover is arranged below the inner liner 22.

[0070] The cover body 20 also usually has a pot opening sealing ring, which can be made of rubber material, for example, and is arranged between the cover body 20 and the inner pot 13 to seal the cooking space when the cover body 20 is in the closed state.

[0071] It can be understood that the cooking appliance 1 according to the present application can be an electric rice cooker, an electric pressure cooker, or other cooking appliance 1, and the cooking appliance 1 can have various functions in addition to the function of cooking rice, such as cooking porridge.

[0072] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 The cooking appliance 1 also has a buffer resistance member 100 arranged on the cover body 20. The buffer resistance member 100 has a damping length L in the width direction D1 of the cover body 20. The buffer resistance member 100 is provided with a cavity structure comprising at least two cavities 110, and the at least two cavities 110 are symmetrically arranged with respect to the median plane P1 of the length on the damping length L. More specifically, the middle plate 11 is provided with a blocking portion 12, which is preferably protruded upward from the middle plate 11. When the cover body 20 is opened to a predetermined angle, the buffer resistance member 100 abuts against the blocking portion 12 to form a damping. In other words, the blocking portion 12 applies a pressing force F to the buffer resistance member 100. Preferably, the blocking portion 12 is provided with a friction surface that can be inclined to face the buffer resistance member 100.

[0073] It is worth mentioning that the shape of the buffer resistance member 100 can be designed as a regular solid shape or a substantially regular solid shape, which has a length (i.e. the above-mentioned damping length L), a width (damping width W), and a height (which can also be understood as a thickness, damping thickness). As described above, the damping length L is in the width direction D1 of the cover body 20, the damping width W is in the front-rear direction D2 of the cover body 20, and the damping thickness is in the thickness direction of the cover body 20.

[0074] It should be noted that in Figure 1 , the direction perpendicular to the paper plane is the front-rear direction D2 of the cover body 20. In Figure 4 and Figure 5In the middle, the direction perpendicular to the paper is the width direction D1 of the cover 20.

[0075] According to the cooking utensil 1 of the present application, when the cover 20 is opened to a predetermined angle, the damper 100 abuts against the pot body 10 to form damping, the symmetrical cavity structure is arranged on the damper 100, which can gently offset the partial cover opening force of the elastic member 30, so that the resultant force on the cover 20 at the end of cover opening is gentle, and further, the cover opening speed at the end of cover opening is gentle.

[0076] The length median plane P1 is perpendicular to the pivot axis AX0 in space, so that the damper 100 is arranged substantially parallel to the pivot axis, so that the deformation of the damper 100 is more uniform when it is extruded. The predetermined angle when the cover is opened can be 55-70°. At this angle, the damping force is provided, so that the cover opening speed is faster, and at the same time, a certain angle is reserved for reducing the cover opening elastic force, so that the cover 20 is opened quickly and stably.

[0077] More specifically, referring to Figure 5 , Figure 6 and Figure 7 , the space in the cavity 110 of the damper 100 is arranged along the thickness direction of the cover 20. As a preferred embodiment, the cavity 110 extends through the damper 100 along the thickness direction. Moreover, the side surface of the damper 100 in the rear direction D2 is configured as a stress surface, so that the opening direction of the cavity 110 is perpendicular to the stress direction, and the space for deformation of the damper 100 can provide a larger damping effect when the elastic potential energy of the elastic member 30 is larger.

[0078] Moreover, forming a gradient change of the damping force in the stress direction is beneficial to make the cover opening reasonable and smooth and linear. Therefore, the cavity is defined to have a cavity cross section, and the cavity cross section is parallel to the thickness direction. The cavity cross section has a cross-sectional width in the width direction D1 of the cover 20. The cross-sectional width has an increasing change trend in the stress direction of the damper 100.

[0079] In order to realize more smooth damping force, so that the resultant force on the cover 20 is more linear, the stress entity part of the damper 100 can be designed to be substantially trapezoidal. The lower side of the trapezoid is configured as a stress surface. Correspondingly, the end portion of the two cavities 110 close to the stress surface has a smaller size, and the end portion of the cavity 110 away from the stress surface has a larger size.

[0080] The cavity 110 has a first end 111 and a second end 112, and the two ends are spaced apart along the front-rear direction D2. The side of the damping member 100 corresponding to the first end 111 is configured as the force receiving surface described above, so that the force receiving direction is the direction from the first end 111 to the second end 112. In addition, the cavity 110 has a straight edge 114 extending along the front-rear direction D2, and the distance between the edge of the cavity 110 and the length median plane P1 is the largest at the straight edge 114. In other words, the straight edge 114 is connected between the first end 111 and the second end 112, and the straight edge 114 is located on the outside of the cavity 110 relative to the length median plane P1.

[0081] The dimension of the cavity 110 along the width direction D1 (the cross-sectional width of the cavity cross section) is the smallest at the first end 111, and the cross-sectional width at the first end 111 is smaller than the cross-sectional width at the second end 112. In the illustrated embodiment, the cross-sectional width of the cavity cross section is the largest at the second end 112.

[0082] As a preferred implementation form, at least part of the cavity 110 gradually decreases in dimension along the width direction D1 in the direction from the second end 112 to the first end 111. In other words, along the force receiving direction, the cross-sectional width of the cavity cross section gradually increases. In this way, the solid structure part between the two cavities 110 can be roughly formed as a trapezoid, so that the resultant force on the cover body 20 is closer to linear. The profile shape of the cavity 110 itself is roughly configured as a triangle as shown in the figure.

[0083] Reference Figure 6 And Figure 7 In order to reduce the damping force fluctuation caused by the large deformation of the damping block, the damping member 100 is further provided with a resistance adjusting structure 113 extending from the edge of the cavity 110 to the inside of the cavity 110.

[0084] In the present embodiment, the cavity 110 has an inclined edge 115 inclined relative to the length median plane P1, and the inclined edge 115 includes at least two sections with different slopes, and the connection between the two adjacent sections forms a turning portion 116, and the turning portion 116 is configured as the resistance adjusting structure 113.

[0085] As an implementation form, in order to provide a more linear damping resistance, the ratio of the maximum dimension of the cavity 110 of the damping member 100 in the front-rear direction D2 to the damping width W of the damping member 100 is 0.38 to 0.58. The maximum dimension of the cavity 110 of the damping member 100 in the width direction D1, or rather the maximum cross-sectional width of the cavity cross-section, to the damping length L of the damping member 100 is 0.23 to 0.28. The ratio of the minimum distance between the two cavities 110 in the width direction D1 to the damping length L of the damping member 100 is 0.25 to 0.31. The ratio of the minimum distance between the cavity 110 and the edge of the damping member 100, specifically the edge in the width direction D1, to the damping length L of the damping member 100 is 0.09 to 0.13.

[0086] In addition, the ratio of the distance between the resistance adjustment structure 113 and the first end 111 in the front-rear direction D2 to the damping width W of the damping member 100 is 0.47 to 0.51. In other words, the ratio of the distance between the connection point between two adjacent slope-different sections of the hypotenuse 115 and the first end 111 in the front-rear direction D2 to the damping width W of the damping member 100 is 0.47 to 0.51.

[0087] Second Embodiment

[0088] Figure 8 The second embodiment of the present invention is shown. The second embodiment of the present invention is a variation of the first embodiment. Except for the damping member 200, the cooking appliance 1 of the third preferred embodiment has a structure and / or configuration similar to that of the cooking appliance 1 of the first preferred embodiment. Therefore, elements having substantially the same functions as those in the first preferred embodiment will be numbered the same here, and for the sake of brevity, they will not be described in detail and / or illustrated again.

[0089] In this embodiment, the cavity 210 of the damping member 200 includes a side cavity 217, an end cavity 218, and a transition cavity 219. Among them, the side cavity 217 extends in the front-rear direction D2, and both the end cavity 218 and the transition cavity 219 extend in the width direction D1. The side edge of the side cavity 217 far from the length mid-plane P1 is the straight edge 114.

[0090] The end cavity 218 communicates with the second end 112 of the side cavity 217. The transition cavity 219 is located between the first end 111 and the second end 112 and communicates with the side cavity 217. The transition cavity 219 is spaced apart from the end cavity 218 via a partition portion 22, and the partition portion 220 forms the resistance adjustment structure 113. Thus, the entire cavity 210 generally forms half of the character "tu", which can make the solid structure between the two cavities 210 also have a trapezoidal configuration generally, while strengthening the stepped change of the damping resistance and being able to adapt to an elastic member with a relatively large stepped change in elastic force.

[0091] In the present embodiment, the dimension of the transition cavity 219 in the width direction D1 is equal to the dimension of the end cavity 218 in the width direction D1, and the dimension of the partition portion 220 in the width direction D1 is equal to the dimension of the end cavity 218 in the width direction D1.

[0092] In the present embodiment, there is also an increasing trend in the cross-sectional width in the force direction of the shock absorber 100. For example, referring to Figure 8 , the cross-sectional width of the cavity cross-section is the smallest at the first end 111 and the largest at the second end 112, thereby forming a trend of increasing cross-sectional width. Again, for example, the cross-sectional width of the transition cavity 219 is equal to the cross-sectional width of the end cavity​​​​​​​​​​​​​​​​​Unless otherwise defined, technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of this application.
