Description

Technical Field

[0001] The invention relates to the technical field of kitchen equipment, and in particular to a change in a pressure relief mode of a cooking appliance. Background Art

[0002] After cooking the food, the electric pressure cooker needs to release the steam in the pot before opening the lid to avoid scalding the user due to excessive pressure in the pot. In order to ensure that the steam in the pot can be fully released before opening the lid, the user needs to lift the pressure limiting valve to release the pressure in the pot before opening the lid.

[0003] However, in the existing electric pressure cookers, the structure of the mechanism for lifting the pressure-limiting valve is unreasonable. Usually, a button structure that reciprocates up and down needs to be set on the pot cover as a driving element for lifting the pressure-limiting valve. The upward resetting movement of the button structure requires the external force of other structural elements. This not only increases the risk of the button structure failing to reset normally due to a functional failure of the resetting force-applying element, but also increases the probability of the button structure getting stuck in the movement channel, seriously affecting the stability of the electric pressure cooker. In addition, the use of the button structure also increases the complexity of the mechanism for lifting the pressure-limiting valve, thereby increasing the overall processing and manufacturing cost of the electric pressure cooker, which is not conducive to market sales. Summary of the invention

[0008] Furthermore, the pressing end is a pressing plane, and the cross-sectional area of ​​the pressing arm gradually decreases in the direction away from the pressing plane, so that the surface of the pressing arm facing the lever element includes a connected pressing plane and an avoidance curved surface.

[0009] Furthermore, the exhaust push button also includes a buckle, which is arranged on the pressing arm and spaced apart from the push plate to form an escape space between the push plate and the buckle for engaging with the face cover.

[0010] Further, the buckle is a wedge-shaped buckle whose cross-sectional area gradually decreases in a direction away from the pressing end of the lever element.

[0011] Furthermore, a portion of the lever element protrudes toward one side of the exhaust push button to form a smoothly transitioned protruding structure, and the protruding structure forms the exhaust pressing end.

[0012] Furthermore, the lever element includes a connected lifting plate section and a bending plate section, wherein the lifting plate section is connected to the pot cover body, the protruding structure is formed on the bending plate section, a first angle A is formed between the lifting plate section and the bending plate section, the pressure limiting valve and the long sliding hole are arranged at intervals along the circumference of the surface cover, and a line connecting the end points of the pressure limiting valve and the long sliding hole on the side of the sealing position close to the exhaust push button forms a second angle B with the length direction of the long sliding hole, and the first angle A is equal to the second angle B.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In order to solve the problem in the prior art that the mechanism for lifting the pressure limiting valve is complicated, it is usually necessary to set a button structure for up and down reciprocating movement on the pot cover, the button structure has a high risk of failing to reset normally, and has a high probability of getting stuck in the movement channel, which seriously affects the poor stability of the electric pressure cooker and increases the overall processing and manufacturing cost of the electric pressure cooker. The present invention provides a cooking utensil. It should be noted that the cooking utensil of the present application includes an electric pressure cooker or an electric rice cooker, but is not limited to the two. The illustrated embodiments of the present application take an electric pressure cooker as an example.

[0031] like Figures 1 to 7As shown, the cooking appliance includes a pot body 10, a pot cover 20, a pressure limiting valve 30, a lever element 40 and an exhaust push button 50, wherein the pot cover 20 is covered on the pot body 10, an exhaust channel 21 is provided on the pot cover 20, the pressure limiting valve 30 is arranged at the exhaust channel 21, the lever element 40 is pivotally arranged on the pot cover 20, the first end of the lever element 40 is located below the pressure limiting valve 30, the second end of the lever element 40 is an exhaust pressing end 41, and the exhaust push button 50 slides on the surface of the pot cover 20, and has an exhaust position and a sealing position on its sliding path; when the exhaust push button 50 is in the exhaust position, the exhaust push button 50 presses the exhaust pressing end 41, so that the first end of the lever element 40 moves upward and lifts the pressure limiting valve 30 to release the steam in the pot body 10, and when the exhaust push button 50 is in the sealing position, the lever element 40 avoids the exhaust pressing end 41, and the pressure limiting valve 30 seals the exhaust channel 21 under the action of its own gravity.

[0032] By arranging a sliding exhaust push button 50 on the surface of the pot cover 20, the user only needs to push or pull the exhaust push button 50 to easily drive the exhaust push button 50 to reciprocate between the exhaust position and the sealing position, thereby smoothly lifting the pressure limiting valve 30 to release the steam in the pot body 10 and achieve pressure relief of the cooking appliance. Moreover, the exhaust push button 50 reciprocates between the exhaust position and the sealing position without the need for the force applied by an external elastic element, which not only reduces the risk of the exhaust push button 50 getting stuck or failing to reset normally, but also simplifies the complexity of the mechanism for lifting the pressure limiting valve 30, reduces the increase in the overall processing and manufacturing cost of the cooking appliance, and is conducive to improving the market competitiveness of the cooking appliance.

[0033] In addition, it should be noted that the exhaust method provided in the present application utilizes pushing the exhaust push button 50 to lift the pressure limiting valve 30. The exhaust push button 50 will not occupy too much space, thereby not affecting the overall size of the pot cover 20, which is conducive to the miniaturization and sophisticated design of the cooking appliance.

[0034] In the illustrated embodiment of the present application, Figures 4 to 7 As shown, the pot cover 20 includes a pot cover body 22 and a surface cover 23, the surface cover 23 is covered on the pot cover body 22, the lever element 40 is connected to the pot cover body 22 or the surface cover 23, and is located between the pot cover body 22 and the surface cover 23, the surface cover 23 is provided with a sliding long hole 231, the exhaust push button 50 is arranged on the surface cover 23 and slides along the length direction of the sliding long hole 231, and a part of the exhaust push button 50 extends into the sliding long hole 231 to press the lever element 40. In this way, the sliding long hole 231 plays a guiding role for the exhaust push button 50, and the wall surfaces at both ends of the length direction of the sliding long hole 231 can also play a role in limiting the sliding of the exhaust push button 50. The lever element 40 is selectively connected to the pot cover body 22 or the surface cover 23, which improves the flexibility of the arrangement of the lever element 40.

[0035] like Figures 2 to 8 As shown, specifically, a limiting groove 232 is provided on the cover 23, and the sliding long hole 231 is located on the groove bottom wall of the limiting groove 232. The exhaust push button 50 includes a push plate 51 and a pressing arm 52, wherein the push plate 51 is arranged in the limiting groove 232 and slides along the length direction of the sliding long hole 231, the first end of the pressing arm 52 is connected to the push plate 51, and the second end of the pressing arm 52 extends into the sliding long hole 231 to serve as a pressing end for pressing the lever element 40. The groove wall of the limiting groove 232 further plays a role in limiting the sliding of the exhaust push button 50, preventing the exhaust push button 50 from falling out of the limiting groove 232, and also plays a role in protecting the exhaust push button 50, preventing the push plate 51 from being worn.

[0036] Since the exhaust push button 50 includes a push plate 51 and a pressing arm 52, when the user pushes the push plate 51 to make it slide in the limiting groove 232, the pressing arm 52 also moves at the same time, and when the exhaust push button 50 moves from the sealing position to the exhaust position, the pressing end of the pressing arm 52 completes the process of pressing the lever element 40, so that the exhaust pressing end 41 of the lever element 40 moves downward, and the first end of the lever element 40 moves upward to lift the pressure limiting valve 30.

[0037] Optionally, in order to facilitate the user to push the exhaust push button 50 , the upper surface of the push plate 51 is provided with anti-skid ridges 512 , and the anti-skid ridges 512 are multiple and are spaced apart along the length direction of the push plate 51 .

[0038] In this embodiment, if Figure 8 As shown, the pressing end is a pressing plane 521, and the cross-sectional area of ​​the pressing arm 52 gradually decreases in the direction away from the pressing plane 521, so that the surface of the pressing arm 52 facing the lever element 40 includes the pressing plane 521 and the avoidance curved surface 522 connected to each other. In this way, the pressing end is the pressing plane 521, which is conducive to increasing the contact area between the pressing arm 52 and the lever element 40, thereby facilitating the improvement of the stability of the rotation of the lever element 40; because the surface of the pressing arm 52 facing the lever element 40 includes the pressing plane 521 and the avoidance curved surface 522 connected to each other, and the pressing plane 521 and the avoidance curved surface 522 have a smooth transition, it is conducive to the contact position of the pressing arm 52 and the lever element 40 to continuously slide and change, thereby smoothly achieving the pressing of the lever element 40.

[0039] like Figure 8As shown, in order to improve the stability of the exhaust push button 50 when assembled on the pot cover 20 and prevent the exhaust push button 50 from falling out of the sliding slot 231, the exhaust push button 50 further includes a buckle 53, which is arranged on the pressing arm 52 and spaced apart from the push plate 51, so as to form an escape space 511 for engaging with the surface cover 23 between the push plate 51 and the buckle 53. In this way, the escape space 511 is used to escape part of the surface cover 23, so that the exhaust push button 50 is stably stuck on the surface cover 23, and the exhaust push button 50 is prevented from falling out along the axial direction of the pot cover 20.

[0040] Optionally, the buckle 53 is a wedge-shaped buckle whose cross-sectional area gradually decreases in the direction away from the pressing end of the lever element 40. This type of buckle 53 facilitates the assembly between the exhaust push button 50 and the cover 23, that is, when the exhaust push button 50 is pressed into the sliding slot 231 along the axial direction of the pot cover 20 by external force, the cover 23 will be continuously deformed, and when the escape space 511 of the exhaust push button 50 moves a certain distance and part of the cover 23 enters the escape space 511, the assembly operation of the exhaust push button 50 and the cover 23 is bent and sunken.

[0041] like Figures 4 to 7 and Fig. 9 As shown, in order to facilitate cooperation with the exhaust push button 50 and ensure that the lever element 40 has a lower processing and manufacturing cost, a portion of the lever element 40 protrudes toward one side of the exhaust push button 50 to form a smoothly transitioned protruding structure, and the protruding structure forms the exhaust pressing end 41.

[0042] Specifically, if Figure 3 and Fig. 9 As shown, the lever element 40 includes a lifting plate section 42 and a bending plate section 43 connected to each other, wherein the lifting plate section 42 is connected to the pot cover body 22, a protruding structure is formed on the bending plate section 43, a first angle A is formed between the lifting plate section 42 and the bending plate section 43, the pressure limiting valve 30 and the sliding long hole 231 are arranged at intervals along the circumference of the surface cover 23, and a line connecting the end points of the pressure limiting valve 30 and the sliding long hole 231 on the sealing position side close to the exhaust push button 50 forms a second angle B with the length direction of the sliding long hole 231, and the first angle A is equal to the second angle B.

[0043] This setting position relationship between the pressure limiting valve 30 and the long sliding hole 231 is based on the consideration that after the long sliding hole 231 is opened on the surface cover 23 and the exhaust push button 50 is installed at the long sliding hole 231, the pot cover 20 is ensured to have a good appearance and is convenient for the user to operate the exhaust push button 50; and the lever element 40 includes a connected lifting plate section 42 and a bending plate section 43 in order to adapt to the above-mentioned setting position relationship between the pressure limiting valve 30 and the long sliding hole 231.

[0044] like Figure 6 and Figure 7As shown, the cooking appliance further includes a switch element 60 and a warning element, wherein the switch element 60 is disposed on the pot cover 20. When the exhaust push button 50 slides to the exhaust position, the exhaust push button 50 triggers the switch element 60, and the switch element 60 controls the warning element to send a warning signal. In this way, the warning element serves as a reminder to the user, preventing the user from forgetting to push the exhaust push button 50 back to the sealing position, further improving the practicality of the cooking appliance.

[0045] Optionally, the switch element 60 is a micro switch, and the warning signal is a sound alarm signal, a vibration alarm signal or a light alarm signal.

[0046] In an optional embodiment of the present application, the pot cover 20 is rotatably disposed on the pot body 10 around the circumference of the pot body 10 to achieve locking or unlocking between the pot cover 20 and the pot body 10, wherein the pot cover body 22 of the pot cover 20 includes a locking cover for snap-fitting with the pot body 10.
