Description

Technical Field

[0001] This utility model relates to the field of small household appliance technology, and more specifically, to a stop plate for a cooking utensil and the cooking utensil itself. Background Technology

[0002] The cooking appliances in this technology utilize the principle that the boiling point of a liquid increases under higher pressure, allowing water to reach a higher temperature without boiling, thus accelerating the cooking process. The cookware's stop plate engages with a stop rod on the lid. The first end of the stop plate is connected to a stop valve, and the second end has a stop hole. When pressure is applied, the stop rod rises. When the stop hole engages with the stop rod, the stop valve is in a stop-opening state, preventing the lid from rotating. When attempting to open the lid, the stop valve abuts against the latches on the pot body, causing the stop plate to move backward. The rising stop rod then prevents the lid from opening, ensuring safety and preventing it from being opened after pressure. When the stop hole and stop rod are in a clearance engagement, the stop rod descends, and the stop valve is in a clearance state that allows the lid to rotate.

[0003] However, when the user forcibly opens the lid due to error, the stress on the stop plate is mainly concentrated at the stop head, resulting in a large deformation of the stop plate. Under normal lid-closing conditions, the teeth of the stop head and the pot body are prone to wear, and after long-term use, the lid is prone to jamming. Utility Model Content

[0004] The main purpose of this utility model is to provide a stop plate for a cooking appliance and the cooking appliance itself, so as to solve the problem of large deformation of the stop plate in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a stop plate for a cooking utensil is provided for cooperating with a stop rod on the lid of the cooking utensil. The stop plate includes: a first plate segment having a connecting hole for connecting a stop head; a second plate segment arranged at an angle to the first plate segment having a stop hole, wherein when the stop hole cooperates with the stop rod, the stop head is in a stop-open state that prevents the lid from rotating; and when the stop hole cooperates with the stop rod, the stop head is in a avoidance state that allows the lid to rotate; and a reinforcing part provided on the first and second plate segments, extending from the connecting hole to the stop hole.

[0006] By applying the technical solution of this utility model, when a user forcibly opens the lid due to error, the reinforced part strengthens the structural strength of the first and second plate segments. Furthermore, the stress on the stop plate is primarily transferred from the connecting hole of the stop head to the stop hole. Since the stop hole cooperates with the stop rod, the structural strength at the stop hole is improved, further enhancing the overall structural strength of the stop plate and reducing its deformation. This reduces the possibility of wear on the fastening teeth of the stop head and the pot body during normal lid closing, effectively minimizing the jamming phenomenon that occurs when closing the lid after prolonged use. Therefore, the technical solution of this application effectively solves the problem of excessive deformation of the stop plate in related technologies.

[0007] Furthermore, the end face of the first plate segment furthest from the second plate segment is designated as the first end face, and the reinforcing portion extends from the connecting hole to the first end face. This structure further increases the strength of the stop plate. When a user attempts to forcibly open the lid, the reinforcing portion effectively disperses the stress on the connecting hole of the stop plate, reducing deformation of the stop plate at the connecting hole location, thereby reducing wear on the threads of the stop plate and the pot body, and improving product safety and durability.

[0008] Furthermore, the end face of the second plate segment furthest from the first plate segment is the second end face, and the reinforcing part extends from the connecting hole to the second end face. This structure ensures improved structural strength throughout the entire length of the stop plate. This design prevents excessive deformation at any point along the length of the stop plate, maintaining stability under engagement forces and enhancing its reliability.

[0009] Furthermore, the first plate segment and the second plate together form a plate body. The plate body has a first surface and a second surface arranged opposite to each other. The reinforcing part includes a reinforcing groove on the first surface and a reinforcing protrusion on the second surface, with the reinforcing protrusion corresponding to the reinforcing groove. The aforementioned plate body has reinforcing grooves and reinforcing protrusions on both sides, forming a structurally reinforced reinforcing part that effectively increases the bending strength and torsional resistance of the stop plate. This double-sided reinforcement design makes the stress distribution more uniform when the stop plate is under pressure, reducing stress concentration and thus extending the service life of the stop plate.

[0010] Furthermore, the difference between the reinforcing protrusion and the reinforcing groove is within the range of 2mm to 4mm. By controlling the difference between the reinforcing protrusion and the reinforcing groove within the range of 2mm to 4mm, it can be ensured that the stop plate maintains sufficient strength and stability while being lightweight.

[0011] Furthermore, the thickness of the first plate segment is equal to the thickness of the second plate segment, and the thickness of the first plate segment is within the range of 1.5mm to 2mm. Maintaining the same thickness between the first and second plate segments ensures the overall uniformity of the stop plate, avoiding uneven stress distribution and structural weakening caused by uneven thickness. Simultaneously, designing the thickness within the range of 1.5mm to 2mm allows for lightweighting of the stop plate, reducing production costs while ensuring structural strength.

[0012] Furthermore, there is at least one reinforcement. By providing at least one reinforcement, structural reinforcement can be specifically applied to the connection holes of the stop plate, which reduces material usage and increases the strength of the connection holes of the stop plate, effectively reducing the risk of deformation of the stop plate under normal use conditions.

[0013] Furthermore, there are two reinforcing parts, which are spaced apart along the width direction of the stop plate. By providing two spaced reinforcing parts in the width direction of the stop plate, the stop plate can be evenly reinforced, so that the deformation of the stop plate is symmetrically distributed, further enhancing the bending and torsional resistance of the stop plate.

[0014] Furthermore, the stop plate also includes a third plate segment connecting the first and second plate segments. Reinforcing elements are sequentially disposed on the first, third, and second plate segments, with the first plate segment extending horizontally. This structure enhances the overall structural strength and rigidity of the stop plate. The third plate segment not only increases the mechanical stability of the stop plate but also, through the distribution of reinforcing elements, effectively disperses stress during engagement or disengagement, reducing localized wear and extending the overall service life of the stop plate.

[0015] According to another aspect of the present invention, a cooking utensil is provided, including a pot body, a pot lid covering the pot body, and a stop plate movably disposed on the pot lid, wherein the stop plate is the stop plate of the cooking utensil described above.

[0033] like Figures 1 to 5 As shown, this application provides a stop plate for a cooking utensil, which is used to cooperate with a stop rod 11 on the lid 10 of the cooking utensil. The stop plate includes a first plate segment 20, a second plate segment 30, and a reinforcing part 40. The first plate segment 20 is provided with a connecting hole 23 for connecting a stop head 21. The second plate segment 30 is set at an angle to the first plate segment 20 and is provided with a stop hole 31. When the stop hole 31 cooperates with the stop rod 11, the stop head 21 is in a stop-open state that prevents the lid 10 from rotating. When the stop hole 31 is in a clearance cooperation with the stop rod 11, the stop head 21 is in a clearance state that allows the lid 10 to rotate. The reinforcing part 40 is provided on the first plate segment 20 and the second plate segment 30, and extends from the connecting hole 23 to the stop hole 31.

[0034] By applying the technical solution of this embodiment, when a user forcibly opens the lid due to error, the reinforcing part 40 strengthens the structural strength of the first plate segment 20 and the second plate segment 30. Furthermore, the stress on the stop plate is mainly transferred from the connecting hole 23 connecting the stop head 21 to the stop hole 31. Since the stop hole 31 cooperates with the stop rod 11, the structural strength at the stop hole 31 is improved, further enhancing the overall structural strength of the stop plate and reducing its deformation. This reduces the possibility of wear on the teeth 61 of the stop head 21 and the pot body 60 when the lid 10 is normally screwed on, effectively reducing the jamming phenomenon that occurs when screwing on the lid 10 after prolonged use. Therefore, the technical solution of this embodiment effectively solves the problem of large deformation of the stop plate in related technologies.

[0035] like Figures 1 to 5As shown, the end face of the first plate segment 20 furthest from the second plate segment 30 is the first end face 22, and the reinforcing part 40 extends from the connecting hole 23 to the first end face 22. By extending the reinforcing part 40 from the connecting hole 23 to the first end face 22, the strength of the stop plate can be further increased. When a user attempts to forcibly open the lid, the reinforcing part 40 can effectively disperse the stress on the connecting hole 23 connecting the stop plate 21, reducing the deformation of the stop plate at the connecting hole 23, thereby reducing the wear of the fasteners 61 of the stop plate 21 and the pot body 60, and improving the safety and durability of the product.

[0036] like Figures 1 to 3 As shown, the end face of the second plate segment 30 furthest from the first plate segment 20 is the second end face 32, and the reinforcing part 40 extends from the connecting hole 23 to the second end face 32. The extension of the reinforcing part 40 from the connecting hole 23 to the second end face ensures improved structural strength throughout the entire length of the stop plate. This design prevents excessive deformation at any point along the length of the stop plate, ensuring its stability under engagement forces and enhancing its reliability.

[0037] like Figures 1 to 3 As shown, the first plate segment 20 and the second plate together form a plate body. The plate body has a first surface 33 and a second surface 34 disposed opposite to each other. The reinforcing part 40 includes a reinforcing groove 41 disposed on the first surface 33 and a reinforcing protrusion 42 disposed on the second surface 34, with the reinforcing protrusion 42 corresponding to the reinforcing groove 41. By providing reinforcing grooves and reinforcing protrusions on both sides of the plate body respectively, a reinforcing part 40 for structural reinforcement is formed, which can effectively increase the bending strength and torsional resistance of the stop plate. This double-sided reinforcement design makes the stress distribution of the stop plate more uniform when it is subjected to pressure, reduces stress concentration, and thus extends the service life of the stop plate.

[0038] In this embodiment, the reinforcing protrusion 42 corresponds to the reinforcing groove 41, so that the reinforcing part 40 forms a wavy plate segment. When the user accidentally forces the lid open, the wavy plate segment can withstand a screwing force of more than 200N, preventing forced opening. At the same time, the reinforcement of the wavy plate segment can effectively reduce the stress at the connecting hole 23 of the connecting stop 21, reduce the mechanical wear of the stop 21 and the fastener 61 during screwing, improve the screwing jamming or the peeling of the outer coating of the pot body 60 after long-term use, and extend the service life.

[0039] like Figures 1 to 3As shown, the difference between the reinforcing protrusion 42 and the reinforcing groove 41 is within the range of 2mm to 4mm. By controlling the difference between the reinforcing protrusion and the reinforcing groove within the range of 2mm to 4mm, it can be ensured that the stop plate maintains sufficient strength and stability while being lightweight. This design reduces the weight of the stop plate and lowers material costs, while ensuring the structural strength of the stop plate under high-pressure cooking conditions, avoiding structural failure problems that may be caused by material thinning.

[0040] In this embodiment, the stop plate is preferably made of a rigid material, such as hardware.

[0041] The difference between the reinforcing protrusion 42 and the reinforcing groove 41 is preferably 2mm, 2.8mm, or 4mm.

[0042] like Figures 1 to 3 As shown, the thickness of the first plate segment 20 is equal to the thickness of the second plate segment 30, and the thickness of the first plate segment 20 is within the range of 1.5mm to 2mm. Maintaining the same thickness between the first plate segment 20 and the second plate segment 30 ensures the overall uniformity of the stop plate, avoiding uneven stress distribution and structural weakening caused by uneven thickness. Simultaneously, designing the thickness within the range of 1.5mm to 2mm allows for lightweighting of the stop plate, reducing production costs, while ensuring structural strength, enabling the stop plate to operate stably under high pressure conditions.

[0043] The thickness of the first plate segment 20 is preferably 1.5 mm, 1.8 mm, or 2 mm.

[0044] like Figures 1 to 3 As shown, there is at least one reinforcing part 40. By providing at least one reinforcing part 40, structural reinforcement can be specifically provided at the connection hole 23 of the stop plate, which reduces the amount of material used and increases the strength of the connection hole 23 of the stop plate, effectively reducing the risk of deformation of the stop plate under normal use conditions.

[0045] In this embodiment, the number of reinforcing parts 40 can be one, two, three, four, or more. The number of reinforcing parts 40 is determined according to the width of the stop plate.

[0046] like Figures 1 to 3 As shown, there are two reinforcing parts 40, which are spaced apart along the width direction of the stop plate. By providing two spaced reinforcing parts 40 in the width direction of the stop plate, balanced reinforcement of the stop plate can be achieved, resulting in a symmetrical distribution of deformation and further enhancing its bending and torsional resistance. This design ensures both the strength of the stop plate and its uniform stress distribution in the width direction, improving its reliability and service life.

[0047] like Figures 1 to 3As shown, the stop plate also includes a third plate segment 50 connecting the first plate segment 20 and the second plate segment 30. Reinforcing parts 40 are sequentially disposed on the first plate segment 20, the third plate segment 50, and the second plate segment 30, with the first plate segment 20 extending horizontally. The sequential placement of the reinforcing parts 40 on the first plate segment 20, the third plate segment 50, and the second plate segment 30 can improve the overall structural strength and rigidity of the stop plate. The third plate segment not only increases the mechanical stability of the stop plate but also, through the distribution of the reinforcing parts 40, effectively disperses the stress on the stop plate during the screwing or forced opening process, reducing localized wear and extending the overall service life of the stop plate. Furthermore, the third plate segment 50 allows the stop plate to adapt to the shape of the pot lid 10, facilitating installation.

[0048] This application also provides a cooking utensil, such as Figures 1 to 5 As shown, an embodiment of the cooking appliance includes a pot body 60, a pot lid 10 covering the pot body 60, and a stop plate movably disposed on the pot lid 10. The stop plate is the stop plate of the cooking appliance described above. Since the stop plate described above can solve the problem of large deformation of the stop plate in the related art, the cooking appliance including the stop plate can solve the same technical problem.

[0049] The cooking appliance of this embodiment also includes an outer shell located on the outside of the pot body and an outer cover located on the outside of the pot lid. The retaining teeth 61 of the pot body 60 are located at the edge of the opening of the pot body 60. The anti-opening spring 70 is located between the outer cover and the first plate segment 20. The anti-opening spring 70 applies an elastic force to the first plate segment 20 so that the anti-opening head 21 can reliably abut against the retaining teeth 61 of the pot body 60. In this embodiment, a relief groove 35 is provided on the side wall of the anti-opening hole 31 of the second plate segment 30. The anti-opening rod 11 includes a first rod segment 111 and a second rod segment 112 with an outer diameter smaller than that of the first rod segment 111. The outer diameter of the first rod segment 111 is larger than the groove width of the relief groove 35, and the groove width of the relief groove 35 is larger than the outer diameter of the second rod segment 112.

[0050] Specifically, when opening the lid, the lid 10 moves the stop plate radially along the lid 10, and the clearance groove 35 moves to the second rod segment 112 so that the second rod segment 112 is located within the clearance groove 35, at which point opening the lid is permitted. After closing the lid, the stop rod 11 floats up. When attempting to open the lid again, the first rod segment 111 corresponds to the clearance groove 35, and the first rod segment 111 cannot enter the clearance groove 35. The stop plate cannot move radially along the lid 10, and the stop head 21 abuts against the fastener 61 of the pot body 60, at which point opening the lid is impossible.

[0051] The cooking appliance in this embodiment is an electric pressure cooker. Of course, in embodiments not shown in the figures, the pot body can also be a cup or an inner pot. The cooking appliance can also be a rice cooker, a low-pressure rice cooker, a soy milk maker, a food processor, a stir-fry machine, an electric slow cooker, a multi-functional pot, etc.

[0052] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner and outer contours of each component itself.

[0053] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures. For example, if the device in the figures were inverted, a device described as "above" or "on top of" other devices or structures would subsequently be positioned as "below" or "under" other devices or structures. Thus, the exemplary term "above" can include both "above" and "below." The device may also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatial relative descriptions used herein will be interpreted accordingly.

[0054] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is merely for the purpose of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be construed as limiting the scope of protection of this utility model.
