Description

Cooking utensil
Technical Field
The invention relates to the field of kitchen utensils, in particular to a cooking utensil.
Background
The existing cooking appliances such as pressure cooker products are prevented from being scalded due to the fact that a user forcibly opens the cooker cover when the pressure in the cooker is high, the pressure cooker products are all required to be provided with a cooker cover self-locking mechanism, and the cooker cover is difficult to open when the pressure in the cooker is higher than the pressure for safely opening the cooker cover.
As shown in fig. 1, in order to avoid forced uncovering in the prior art, a common structural scheme of a self-locking mechanism is as follows: a self-locking sliding block assembly is designed, the self-locking sliding block assembly comprises a self-locking sliding block 3 'and a connecting piece 1', the connecting piece 1 'is riveted or welded on the self-locking sliding block 3', a return spring is designed at the tail of the connecting piece 1 ', and power for returning the self-locking sliding block 3' is provided through the return spring. When pressure exists in the cooker, when a user rotates the cooker cover in the opening direction by force, the top of the self-locking sliding block component is blocked by the floater 4 ', and the bottom of the self-locking sliding block 3' interferes with the cooker teeth 21 'of the outer cooker 2', so that the cooker cover is locked to prevent the user from opening the cooker cover.
However, when pressure exists in the product, if a user opens the cover forcibly with great force, the connecting piece 1 'is extruded by the slope surface of the pot teeth 21' of the outer pot 2 ', the connecting piece 1' drives the self-locking slide block 3 'to move towards the radial direction of the pot cover, so that the angle a of the self-locking slide block 3' is increased, wherein, along the length direction of the self-locking slide block 3 ', the self-locking slide block 3' comprises a first end part and a second end part, the first end part is provided with a float hole 5 'for the float 4' to pass through, the second end part is provided with a connecting piece 1 ', the angle A is the angle between the first end part and the second end part, and after the angle A is increased, the interference between the connecting piece 1' and the pot teeth 21 'of the outer pot 2' is reduced. When the cooker cover is rotated continuously, the angle A is increased continuously until the connecting piece 1 ' is not in interference fit with the cooker teeth 21 ' of the outer cooker 2 ', and the cooker cover is opened at the moment. It can be seen that the thicker the self-locking slide block 3' material is, the larger the force for increasing the angle A is, namely, the larger the forced uncovering force is. However, the size of the self-locking sliding block 3 'is small, and the material thickness of the self-locking sliding block 3' cannot be excessively thickened in consideration of manufacturability of parts. Therefore, when the scheme is adopted, the pot cover can be forcibly opened when pressure exists in the pot, so that the user is easily scalded, and therefore, the scheme has great improvement space.

When the connecting piece is matched with the convex part, the connecting piece moves outwards relative to the pot cover along the radial direction of the pot cover under the action of the convex part. When pressure exists in the cooker, the sliding block component is limited at the first position by the floater, the connecting piece cannot drive the sliding block component to move outwards along the cooker cover relative to the radial direction of the cooker cover, and the sliding block component is still at the first position; when no pressure exists in the cooker, the sliding block component can move outwards along the radial direction of the cooker cover relative to the cooker cover, and the connecting piece drives the sliding block component to move to the second position, so that the cover opening is realized.
The cooking utensil comprises an outer pot, and the convex part can be a pot tooth of the outer pot.

As shown in fig. 18, when the pressure in the cooker is higher than the external atmospheric pressure, the float floats upwards, the second float section 72 of the float is positioned in the float hole, and the second float section 72 can only be inserted into the second hole section 3122 but can not be inserted into the first hole section 3121, so that the second float section cannot be matched with the first hole section 3121, and therefore, the slide block assembly cannot move outwards along the radial direction of the cooker cover; as shown in fig. 13, when the pressure in the cooker is less than or equal to the external atmospheric pressure, the float falls to the falling position, the first float section 71 of the float is matched with the float hole, and since the first float section 71 can be matched with the first hole section 3121, when the slide block assembly moves outward along the radial direction of the cooker cover under the action of the cover opening force, the first float section 71 is driven to be matched with the first hole section 3121, so that the slide block assembly can move outward along the radial direction of the cooker cover. The first float section 71 is arranged to increase the length of the float, so that the float is convenient for a user to observe, and further, the upper end part of the first float section 71 is a visible section for the user to observe.
In a second specific embodiment, in the lowered position, the upper end surface of the float is positioned below the float aperture, the float is completely out of contact with the slider assembly, and in the second position the float is disengaged from the float aperture; in the floating position, the float is positioned in the float hole to limit the outward movement of the slider assembly relative to the lid in the radial direction of the lid.
In the above embodiment, as shown in fig. 2 to 6, the cover 1 includes: and the connecting piece 4 is arranged on the sliding block component 3, and can move along the radial direction of the pot cover 12 relative to the sliding block component 3.
The cooker body comprises an outer cooker 22, the upper end of the outer cooker 22 is turned outwards to form a cooker edge 223, the cooker edge 223 is provided with a convex part 221 and a concave part 222, the connecting piece 4 is in sliding fit with the convex part 221 on the cooker body 2, so that the connecting piece 4 moves along the radial direction of the cooker cover 12 under the action of the convex part 221, for example, moves outwards along the radial direction of the cooker cover 2, in the second position, the connecting piece moves outwards along the radial direction of the cooker cover under the action of the convex part 221 and drives the sliding block assembly to move outwards along the radial direction of the cooker cover, and a first elastic piece 5 is supported between the connecting piece 4 and the sliding block assembly 3; the lid body 1 includes a face cover assembly 11, the lid 12 is located inside the face cover assembly 11, the cooking utensil includes a second elastic member 6, the second elastic member 6 is supported between the connecting member 4 and the face cover assembly 11, and the pre-compression elastic force of the second elastic member 6 is smaller than the pre-compression elastic force of the first elastic member 5.
The connecting piece 4 is arranged on the sliding block component 3, rotates along the circumferential direction of the pot body 2 relative to the pot body 2 along with the sliding block component 3 and the pot cover 12, and can move along the radial direction of the pot cover relative to the sliding block component 3. The connecting piece 4, the first elastic piece 5 and the second elastic piece 6 are arranged, so that the cover opening of the cooking utensil in the absence of pressure in the cooker is realized on the premise that the cover opening cannot be carried out in the absence of pressure in the cooker.
As shown in fig. 16 to 19, when pressure is in the cooker, the float 7 is in the floating position lifted by the pressure in the cooker, and the slider assembly 3 is blocked by the float 7, the slider assembly 3 can not move or can only move a small distance relative to the cooker cover 12 along the radial direction of the cooker cover 12, and the slider assembly 3 is in the first position. When the cover 12 is rotated in the cover opening direction, the sliding block assembly 3 and the connecting piece 4 rotate along the circumferential direction of the pot body 2 along with the cover 12, when the cover 12 rotates relative to the pot body 2, the cover 12 drives the connecting piece 4 to rotate along the circumferential direction of the pot body 2, when the connecting piece 4 is matched with the convex part 221, the connecting piece 4 moves relative to the sliding block assembly 3 along the radial direction of the cover 12 under the action of the convex part 221, for example, the connecting piece 4 moves radially outwards along the cover 12 relative to the sliding block assembly 3, the compression amount of the first elastic piece 5 is increased, the second elastic piece 6 is also compressed, and due to the limiting effect of the float 7, the sliding block assembly 3 does not move or only slightly moves relative to the cover 12 in the radial direction of the cover 12. When the lid 12 is rotated to a position where the rotation stop portion 211 corresponds to the rotation stop engagement portion 313, the rotation stop portion 211 engages with the rotation stop engagement portion 313, and the lid 12 cannot be rotated further, so that the lid cannot be opened.
As shown in fig. 11 to 14, when there is no pressure in the pan, the float 7 is in the falling position, the first float section on the float 7 engages with the float aperture, and the slider assembly 3 is movable radially outwardly along the pan lid 12 relative to the pan lid 12. When the lid 12 is rotated in the lid opening direction, the slider 31 and the connecting member 4 move along the circumferential direction of the lid 12 along with the lid 12. When the connecting member 4 passes through the protruding portion 221, the protruding portion 221 drives the connecting member 4 to move radially outward along the lid 12 relative to the lid 12, and since the pre-compression elastic force of the first elastic member 5 is greater than the pre-compression elastic force of the second elastic member 6, when the connecting member 4 moves radially outward along the lid 12 relative to the lid 12, the first elastic member 5 is not compressed continuously, the second elastic member 6 is compressed, and no relative movement occurs between the slider assembly 3 and the connecting member 4, that is, the connecting member 4 drives the slider assembly 3 to move radially outward along the lid 12 relative to the lid 12, so that the slider assembly 3 is located at the second position, the rotation stop portion 211 and the rotation stop mating portion 313 do not interfere with each other, and the lid 12 can continue to rotate in the lid opening direction to open the lid.
The first elastic member 5 and the second elastic member 6 may be coil springs or elastic pieces, etc. The pre-compressed elastic force of the first elastic member 5 and the second elastic member 6 means that after the cover body 1 is assembled, the elastic force of the first elastic member 5 and the second elastic member 6 is the same as that of the state shown in fig. 7 to 10, and the connecting member 4 is not engaged with the protrusion 221 at this time, and the connecting member 4 is engaged with the protrusion 221 only by continuing to rotate the pot cover 12.
The connecting element 4 can be a pin or other cylindrical shaft, and further, the length direction of the connecting element 4 is along the radial direction of the pot cover 12. The connecting piece includes the lower tip that is located the upper end portion of pot cover top and is close to the pot body setting, and float cooperation portion sets up on the upper end portion, and the cooperation portion that splines sets up under the tip. A bend is formed between the upper end part and the lower end part.

The cooking utensil includes outer pot 22, and protruding portion 221 can be the pot tooth of outer pot 22, and along the direction from inside to outside, protruding portion 221 forms the inclined plane to uncapping the direction slope, and the connecting piece cooperatees with the inclined plane, and the inclined plane drives the connecting piece and outwards moves for the pot cover along the radial of pot cover. The protrusion 221 and the rotation stopper 211 are arranged in this order in the lid opening direction, so that the connector 4 is first brought into contact with and engaged with the protrusion 221 and then the rotation stopper 211 is engaged with the rotation stopper engagement portion 313 at the time of opening the lid. Therefore, when there is no pressure in the cooker, after the connecting element 4 is engaged with the protrusion 221, that is, after the connecting element 4 drives the slider assembly 3 to move outward along the radial direction of the cooker cover 12, the rotation stopping part 211 reaches the position corresponding to the rotation stopping engaging part 313, and since the interference between the rotation stopping part 211 and the rotation stopping engaging part 313 is removed, the cover can be opened smoothly.
Further, the protrusion 221 and the rotation stopper 211 are provided in this order in the lid opening direction. In the radial direction of the pot body, the rotation stopping part is arranged at the outer side of the corresponding convex part, namely the distance between the rotation stopping part and the axis of the cooking utensil is larger than the distance between the convex part and the axis of the cooking utensil, so that in the first position, the rotation stopping part and the rotation stopping matching part can interfere with each other, and the cover opening is prevented when the pressure in the pot is larger than the external atmospheric pressure.

To achieve interference between the rotation stop part 211 and the rotation stop fitting part 313, the height of the rotation stop fitting part 313 is between the height of the upper surface of the rotation stop part 211 and the height of the lower surface of the rotation stop part 211, so that the rotation stop part 211 can contact and interfere with the rotation stop fitting part 313 when the pot lid 12 rotates relative to the pot body 2 under pressure in the pot. Further, the rotation stop fitting portion 313 may be a lower end portion of the slider.

In some embodiments, as shown in fig. 19, the surface of the rotation stop portion 211 for cooperating with the rotation stop cooperating portion 313 is a vertical surface, and the surface of the rotation stop portion 211 for cooperating with the rotation stop cooperating portion 313 is a vertical surface.
The surface of the rotation stop part 211 for cooperating with the rotation stop fitting part 313 is a first surface 2111, and the surface of the rotation stop fitting part 313 for cooperating with the rotation stop part 211 is a second surface 3131, so that the contact area between the first surface 2111 and the second surface 3131 can be increased to further increase the force required for opening the lid when pressure is present in the cooker, and thus the shapes of the first surface 2111 and the second surface 3131 are adapted.

Alternatively, the cooking appliance is an electric pressure cooker, a pressure cooker, an air fryer, a steam oven, or the like.
The following describes a specific process of opening the cover of the cooking appliance in one embodiment of the present application:
as shown in fig. 15 to 19, when there is pressure in the cooker, the float 7 is lifted up by the pressure in the cooker, and at this time, the slider 31 is blocked by the float 7, and the slider 31 cannot move in the radial direction of the cooker lid 12 or can move only for a small distance. When the cooker lid 12 is rotated in the lid opening direction, both the sliding block 31 and the connecting piece 4 can move along the circumferential direction of the cooker lid 12 along with the cooker lid 12, when the connecting piece 4 passes through the inclined surface of the convex part 221 of the outer cooker 22, because the connecting piece 4 and the sliding block 31 are not rigidly connected, the connecting piece 4 can also move along the radial direction of the outer cooker 22 in the first through hole and the second through hole of the sliding block 31 at the same time as the connecting piece 4 can rotate along the circumferential direction of the outer cooker 22, at this time, the 1 st spring is pressed by the connecting piece 4, the compression amount of the 1 st spring is increased, the second elastic piece is also compressed, the cooker lid 12 is continuously rotated, when the sliding block 31 passes through the rotation stopping part position of the housing cover 21, because the distance D1 from the outer side surface of the rotation stopping part of the housing cover 21 to the center of the cooker lid 12 is greater than the distance D4 from the bottom of the sliding block 31 to the center of the cooker lid 12, namely D1> D4, at this time, the cooker lid 12 can not be opened because the bottom of the sliding block by the rotation stopping part of the housing cover 21, so that the product cannot be unscrewed from the pot cover 12 when pressure is present in the pot.
As shown in fig. 11 to 14, when there is no pressure in the cooker, the float 7 is in a falling state, the slider 31 is not blocked by the float 7, the slider 31 can move outward along the radial direction of the lid 12, when the lid 12 is rotated in the lid opening direction, both the slider 31 and the connecting member 4 can move along the circumferential direction of the lid 12 along with the lid 12, when the connecting member 4 passes the inclined surface of the convex portion of the outer pot 22, because the pre-compression elastic force of the first elastic member 5 is greater than the pre-compression elastic force of the second elastic member 6, the compression amount of the first elastic member does not change, only the compression amount of the second elastic member becomes larger, that is, the connecting member 4 and the slider 31 do not move relatively, the lid 12 continues to rotate, when the slider 31 passes the rotation stop position of the housing cover 21, because the distance D1 between the outer side surface of the rotation stop portion of the housing cover 21 and the cooking utensil axis is smaller than the distance D2 between the rotation stop mating portion of the slider 31 and the cooking utensil axis, that is, D1< D2, as shown in fig. 13, i.e., the distance D3 from the side of the bottom of the slider 31 (rotation stop fitting portion) close to the lid 12 to the outside of the rotation stop portion of the housing cover 21 is greater than 0, so that the bottom of the slider 31 is not stopped by the rotation stop portion of the housing cover 21, and the lid 12 can be opened, so that the product can be unscrewed from the lid 12 when there is no pressure in the cooker.
In the scheme, when pressure exists in the cooker, a user forcibly rotates the cooker cover 12 in the cover opening direction, when the sliding block 31 passes through the rotation stopping part of the outer housing cover 21, the side wall of the bottom (rotation stopping matching part) of the sliding block 31 is blocked by the rotation stopping part of the outer housing cover 21 to prevent the cooker cover 12 from being opened, so that the main stress position of the sliding block assembly 3 is the stress in the width direction of the sliding block 31, namely, the sliding block 31 can be opened only by large displacement deformation in the width direction, the width of the sliding block 31 is far larger than the thickness of the sliding block 31, in the prior art, when the pressure exists in the cooker, the user forcibly rotates the cooker cover 12 in the cover opening direction, the connecting piece 4 is extruded by the inclined surface of the outer cooker 22, the connecting piece 4 drives the sliding block 31 to move in the radial direction of the cooker cover 12, so that the angle A of the sliding block 31 is increased, after the angle A is increased, the interference magnitude between the connecting piece 4 and the outer pot 22 pot teeth is reduced, when the pot cover 12 is continuously rotated, the angle A is continuously increased until the connecting piece 4 and the outer pot 22 pot teeth are not in interference fit, and the pot cover 12 is opened at the moment. Because the width of the sliding block 31 is far larger than the thickness of the sliding block 31, the force for deforming the sliding block 31 in the width direction is far larger than the force for deforming the sliding block 31 in the angle direction, when pressure exists in the cooker, the force required for forcibly opening the cooker cover 12 in the application is far larger than the force required in the prior art.
In summary, the cover 1 according to the embodiment of the present invention prevents the user from opening the lid when pressure is applied to the cooker. The slide block component structure is as follows: the baffle is connected with slider rigid coupling, has first through-hole and second through-hole respectively in the design on slider and baffle, and the connecting piece is installed in the first through-hole of slider and the second through-hole of baffle, and the first elastic component of round pin epaxial suit, the one end of first elastic component is fixed by the support step, and the other end is fixed by the baffle. The connecting piece can move relative to the sliding block, and when the connecting piece moves relative to the sliding block, the compression amount of the first elastic piece is increased. In addition, a second elastic part is designed at the tail part of the connecting part, one end of the second elastic part is fixed on the connecting part, and after the assembly is completed, the other end of the second elastic part is pressed and fixed by a face cover assembly (the face cover assembly comprises parts such as a face cover or an inner cover, wherein the pot cover is positioned on the upper side of the inner cover, and the face cover is positioned above the inner cover), so that the second elastic part is always in a compression state. In addition, the rotation stopping part is designed on the outer shell cover and can be in a convex hull or groove form, and after the assembly is finished, the rotation stopping matching part at the bottom of the sliding block is lower than the top surface of the convex hull of the outer shell cover or lower than the top surface of the groove of the outer shell cover in the height direction. When pressure exists in the cooker, when the cooker cover is rotated in the opening direction, the rotation stopping matching part at the bottom of the sliding block is blocked by the convex hull side wall of the outer shell cover or the groove side wall of the outer shell cover, the product cannot be opened, when no pressure exists in the cooker, the bottom of the sliding block slides through the outer convex hull side or the groove side of the outer shell cover when the cooker cover is rotated in the opening direction, and the product can be normally opened.
