Description

Technical Field

[0001] The present invention relates to the technical field of cooking utensils, and in particular to a cover body and a cooking utensil having the same. Background Art

[0002] With the development of society and the progress of science, people are increasingly pursuing quality of life. Cooking utensils such as rice cookers and electric frying pans are widely used in people's daily lives and have become indispensable tools in people's lives.

[0003] When the cooking appliance is working, steam will be generated in its cooking space. When the pressure of the steam acting on the pressure relief spring is less than its pre-compression force, the steam cannot be discharged, and then the pressure increases. When the pressure is greater than the pre-compression force of the pressure relief spring, the steam is discharged from the cooking space. At this time, the pressure in the cooking space drops, thus ensuring that the cooking space is finally under a constant cooking pressure.

[0004] Traditional cooking utensils only have one constant cooking pressure, but different foods have different requirements for pressure and different users have different taste requirements for the same food, so the cooking utensils need to have multiple different constant cooking pressures. Therefore, traditional cooking utensils no longer meet people's needs. Summary of the invention

[0033] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0034] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0036] See also Figure 1 An embodiment of the present invention provides a cooking utensil, comprising a cooking body (not shown) and a cover 100, wherein the cover 100 is disposed on the cooking body and defines a cooking space with the cooking body. Specifically, the cooking utensil may be an electric rice cooker or other types of cooking utensil, such as an electric steamer, which is not limited here.

[0037] The following is an example of an electric rice cooker to illustrate the technical solution of the present invention in detail. This embodiment is only used as an example and does not limit the technical scope of the present invention. Furthermore, the drawings in the embodiments also omit unnecessary components and clearly show the technical features of the present invention.

[0038] See also Figure 2 and Figure 3 The cover 100 includes a main body 10 and an exhaust mechanism 20. The main body 10 is disposed at the opening of the cooking main body and is used to open and close the cooking main body according to user operations. The exhaust mechanism 20 is assembled on the main body 10 and is used to adjust the pressure in the cooking space so that the cooking space is kept at a constant cooking pressure to complete cooking of the food in the cooking space.

[0039] See also Figure 4The main body 10 includes a heat preservation cover plate 11, an inner cover 12 and a surface cover (not shown). The heat preservation cover plate 11 is configured to face the inside of the cooking body, and the inner cover 12 is located between the heat preservation cover plate 11 and the surface cover. The surface cover is configured to face the user, and buttons for user operation (such as a cooking mode selection button, a start button, a keep warm button, etc.) can be set on it as needed.

[0040] See also Figure 3 The exhaust mechanism 20 is assembled on the inner cover 12. Specifically, an assembly hole (not shown) is opened on the inner cover 12, and the exhaust mechanism 20 is assembled in the assembly hole. The exhaust mechanism 20 can at least partially move in the assembly hole to adjust the pressure in the cooking space.

[0041] An exhaust port 111 is provided on the heat-insulating cover plate 11, and the exhaust mechanism 20 is used to open or close the exhaust port 111. Specifically, when the pressure generated by the steam in the cooking space is relatively low, the exhaust mechanism 20 closes the exhaust port 111, and when the pressure generated by the steam in the cooking space is relatively high, the exhaust mechanism 20 opens the exhaust port 111, so that the cooking space is finally under a constant cooking pressure.

[0042] In one embodiment, the exhaust mechanism 20 includes an exhaust body 21 and an elastic member 22, wherein the elastic member 22 is mounted on the exhaust body 21, and the exhaust body 21 is used to open or close the exhaust port 111. Specifically, when the pressure generated by the steam in the cooking space is less than the pre-compression elastic force of the elastic member 22, the exhaust body 21 closes the exhaust port 111, and when the pressure generated by the steam in the cooking space is greater than the pre-compression elastic force of the elastic member 22, the exhaust body 21 opens the exhaust port 111, so that the cooking space is finally under a constant cooking pressure. Specifically, the elastic member 22 is a spring.

[0043] Specifically, the exhaust body 21 includes a fixing seat 211 and a sealing member 212. The fixing seat 211 is fixedly connected to the inner cover 12. The sealing member 212 is assembled on the fixing seat 211. One end of the sealing member 212 is used to open or close and seal the exhaust port 111, and the other end is elastically abutted against the fixing seat 211. One end of the elastic member 22 is fixedly connected to the sealing member 212, and the other end is compressed and accommodated in the fixing seat 211. Specifically, when the pressure generated by the steam in the cooking space is less than the pre-compression elastic force of the elastic member 22, the sealing member 212 closes and seals the exhaust port 111. When the pressure generated by the steam in the cooking space is greater than the pre-compression elastic force of the elastic member 22, the sealing member 212 is deformed under the pressure generated by the steam and compresses the elastic member 22 to open the exhaust port 111, so that the cooking space is finally under a constant cooking pressure.

[0044] It is understandable that in another embodiment, the exhaust mechanism 20 may also omit the elastic member 22, and the exhaust mechanism 20 closes the exhaust port 111 under the action of its own weight. Specifically, when the pressure generated by the steam in the cooking space is less than the gravity of the exhaust mechanism 20, the exhaust mechanism 20 closes the exhaust port 111, and when the pressure generated by the steam in the cooking space is greater than the gravity of the exhaust mechanism 20, the exhaust mechanism 20 opens the exhaust port 111. It is conceivable that in some other embodiments, the exhaust mechanism 20 may also be set to close the exhaust port 111 under the dual action of its own weight and pre-compression elastic force. Specifically, when the pressure generated by the steam in the cooking space is less than the self-weight and pre-compression elastic force of the exhaust mechanism 20, the exhaust mechanism 20 closes the exhaust port 111, and when the pressure generated by the steam in the cooking space is greater than the self-weight and pre-compression elastic force of the exhaust mechanism 20, the exhaust mechanism 20 opens the exhaust port 111.

[0045] See also Figure 4-Figure 6 The cover body 100 also includes a pressure regulating mechanism 30, which is assembled on the inner cover 12 and can reciprocate along a first direction relative to the inner cover 12. The pressure regulating mechanism 30 cooperates with the exhaust mechanism 20. Under the action of the pressure regulating mechanism 30, the exhaust mechanism 20 can act on the exhaust port 111 along a second direction intersecting the first direction relative to the thermal insulation cover plate 11 to adjust the pre-pressure of the exhaust mechanism 20 acting on the exhaust port 111.

[0046] For the convenience of description, the exhaust mechanism 20 is described below as including an exhaust body 21 and an elastic member 22 , and the exhaust body 21 includes a fixing seat 211 and a sealing member 212 .

[0047] At this time, the elastic member 22 can be compressed to different degrees along the second direction relative to the thermal insulation cover plate 11 under the action of the pressure regulating mechanism 30 to change the pre-compression elastic force of the sealing member 212 acting on the exhaust port 111 .

[0048] Through the above arrangement, the pressure regulating mechanism 30 can adjust the compression degree of the elastic member 22 along the second direction, thereby adjusting the pre-compression elastic force of the exhaust mechanism 20 acting on the exhaust port 111. Since the pre-compression elastic force of the exhaust mechanism 20 acting on the exhaust port 111 is adjustable, the exhaust pressure required for the exhaust mechanism 20 to open the exhaust port 111 is adjustable, so that a plurality of different constant cooking pressures can be provided in the cooking space, meeting people's needs.

[0049] It can be understood that in other embodiments, when the exhaust mechanism 20 closes the exhaust port 111 under the action of its own weight, the pressure regulating mechanism 30 can adjust the gravity of the exhaust mechanism 20. For example, the exhaust mechanism 20 is configured to include multiple parts. When the regulating mechanism 30 reciprocates along a first direction relative to the inner cover 12, a part of the exhaust mechanism 20 can be lifted or lowered along a second direction to change the weight of the exhaust mechanism 20, thereby adjusting the pre-pressure gravity of the exhaust mechanism 20 acting on the exhaust port 111.

[0050] In this specific embodiment, the first direction and the second direction are arranged perpendicularly, such as when the pressure cooking device is placed on a horizontal work surface, the first direction is the horizontal cross-sectional direction of the pressure cooking device, and the second direction is the height cross-sectional direction of the pressure cooking device. It can be understood that in other embodiments, the first direction and the second direction may also be arranged non-perpendicularly, which is not limited here.

[0051] Furthermore, the pressure regulating mechanism 30 performs reciprocating linear motion along the first direction relative to the inner cover 12. It can be understood that in other embodiments, the pressure regulating mechanism 30 can also perform reciprocating curved motion along the first direction relative to the inner cover 12, which is not limited here.

[0052] See also Figure 4 The cover body 100 further includes a first matching member 50 and a first actuating structure. The first matching member 50 is mounted on one of the exhaust mechanism 20 and the pressure regulating mechanism 30, and the first actuating structure is mounted on the other of the exhaust mechanism 20 and the pressure regulating mechanism 30. Thus, when the pressure regulating mechanism 30 moves in a first direction relative to the inner cover 12, the exhaust mechanism 20 is driven to act on the exhaust port 111 in a second direction relative to the inner cover 12 through the cooperation of the first matching member 50 and the first actuating structure.

[0053] In the first embodiment, the first actuating structure is configured as a first inclined portion that is inclined relative to the first direction and the second direction, and the first mating piece 50 is configured as a sliding piece. The exhaust mechanism 20 and the pressure regulating mechanism 30 are engaged in sliding friction with the sliding piece through the first actuating structure to drive the exhaust mechanism 20 to act on the exhaust port 111 along the second direction relative to the inner cover 12.

[0054] See also Figure 5-Figure 7 Specifically, the first inclined portion is configured as a first inclined surface 40 that is inclined relative to both the first direction and the second direction. It can be understood that in other embodiments, the first inclined portion is configured as two first sub-inclined surfaces that are inclined relative to both the first direction and the second direction, and the two first sub-inclined surfaces are connected to form a V-shape with an uphill section and a downhill section, so that the exhaust mechanism 20 can be controlled by moving in both directions (reciprocating direction in the first direction).

[0055] In the second embodiment, the first actuating structure is configured as a first inclined portion that is inclined relative to the first direction and the second direction, and the first mating member 50 is configured as a rolling member. The exhaust mechanism 20 and the pressure regulating mechanism 30 are matched with each other through rolling friction between the first actuating structure and the rolling member to drive the exhaust mechanism 20 to act on the exhaust port 111 along the second direction relative to the inner cover 12. The rolling friction matching has relatively small friction force and high sensitivity, thereby making the pressure regulation accuracy of the pressure regulating mechanism 30 higher.

[0056] Specifically, the first inclined portion is configured as a first inclined surface 40 that is inclined relative to both the first direction and the second direction. It can be understood that in other embodiments, the first inclined portion is configured as two first sub-inclined surfaces that are inclined relative to both the first direction and the second direction, and the two first sub-inclined surfaces are connected to form a V-shape with an uphill section and a downhill section, so that the exhaust mechanism 20 can be controlled by moving in both directions (reciprocating direction in the first direction).

[0057] In the first and second embodiments, for ease of arrangement, the first inclined surface 40 of the first actuating structure is formed on the pressure regulating mechanism 30, and the first matching member 50 (rolling member or sliding member) is assembled at one end of the exhaust mechanism 20 that abuts against the pressure regulating mechanism 30, so that when the pressure regulating mechanism 30 moves relative to the inner cover 12, a component force of the first inclined surface 40 of the first actuating structure acting on the first matching member 50 drives the first matching member 50 to drive the elastic member 22 to be compressed and deformed along the second direction relative to the inner cover 12. It can be understood that in another embodiment, the first inclined surface 40 of the first actuating structure can also be opened on the exhaust mechanism 20, and the first matching member 50 is assembled on the pressure regulating mechanism 30, which is not limited here.

[0058] In another embodiment, the difference from the above two embodiments lies in that the first actuating structure further includes a roller, which is disposed on the first inclined portion, and the roller of the first actuating structure is in contact with the first mating piece 50. When the pressure regulating mechanism 30 moves along the first direction relative to the inner cover 12, a component force of the roller of the first actuating structure acting on the first mating piece 50 will drive the first mating piece 50 to drive the elastic piece 22 to be compressed and deformed along the second direction relative to the inner cover 12.

[0059] In a specific embodiment, the first inclined surface 40 is disposed on the pressure regulating mechanism 30, and the first matching member 50 is disposed on the exhaust mechanism 20. Figure 8 and Fig. 9 Specifically, the first matching member 50 includes a first cylinder 51 with a top wall and a first extension column 52 extending from the outer wall of the first cylinder 51. The first cylinder 51 is arranged in the fixed seat 211 of the exhaust mechanism 20 and is sleeved outside the end of the elastic member 22 that is not connected to the sealing member 212. The first extension column 52 is inserted outside the fixed seat 211, and the first inclined surface 40 is matched with the protruding end of the first extension column 52. In this way, when the pressure regulating mechanism 30 reciprocates relative to the inner cover 12 along the first direction, the pre-compression elastic force of the elastic member 22 acting on the sealing member 212 can be adjusted under the cooperation of the first inclined surface 40 and the first extension column 52, so that the cooking space can have a plurality of different constant cooking pressures, meeting people's needs.

[0060] See also Figure 4 and Figure 5 In one embodiment, the cover body 100 further includes a pressure relief mechanism 60, which can reciprocate along a first direction relative to the inner cover 12. The pressure relief mechanism 60 cooperates with the exhaust mechanism 20, and the exhaust mechanism 20 can move along a second direction relative to the inner cover 12 under the action of the pressure relief mechanism 60, so that the exhaust mechanism 20 can fully open the exhaust port 111.

[0061] Through the above arrangement, the cover body 100 can not only adjust the constant cooking pressure in the cooking space through the pressure regulating mechanism 30 , but also achieve complete pressure relief in the cooking space through the pressure relief mechanism 60 .

[0062] Specifically, the pressure relief mechanism 60 is integrally provided with the pressure regulating mechanism 30. It is conceivable that in some other embodiments, the pressure relief mechanism 60 and the pressure regulating mechanism 30 may also be separately provided, which is not limited here.

[0063] See also Figure 6 and Figure 7 The cover body 100 further includes a second matching member 80 and a second actuating structure. The second matching member 80 is mounted on one of the exhaust mechanism 20 and the pressure relief mechanism 60, and the second actuating structure is mounted on the other of the exhaust mechanism 20 and the pressure relief mechanism 60. Thus, when the pressure relief mechanism 60 moves in the first direction relative to the inner cover 12, the second matching member 80 cooperates with the second actuating structure to drive the exhaust mechanism 20 to move in the second direction relative to the inner cover 12 to open the exhaust port 111 and achieve complete pressure relief.

[0064] In one embodiment, the second actuating structure is configured as a second inclined portion that is inclined relative to the first direction and the second direction, and the second mating piece 80 is configured as a sliding piece. The exhaust mechanism 20 and the pressure relief mechanism 60 are engaged in sliding friction with the sliding piece through the second actuating structure to drive the exhaust mechanism 20 to move along the second direction relative to the inner cover 12 to open the exhaust port 111 to achieve complete pressure relief.

[0065] Specifically, the second inclined portion is configured as a second inclined surface 70 that is inclined relative to both the first direction and the second direction. It can be understood that in other embodiments, the second inclined portion is configured as two second sub-inclined surfaces that are inclined relative to both the first direction and the second direction, and the two second sub-inclined surfaces are connected to form a V-shape with an uphill section and a downhill section, so that complete pressure relief control of the exhaust mechanism 20 can be achieved through movement in both directions (reciprocating direction in the first direction).

[0066] In another embodiment, the second actuating structure is configured as a second inclined portion that is inclined relative to the first direction and the second direction, and the second mating piece 80 is configured as a rolling piece. The exhaust mechanism 20 and the pressure relief mechanism 60 are matched with each other through rolling friction between the second actuating structure and the rolling piece to drive the exhaust mechanism 20 relative to the inner cover 12 along the second direction to achieve complete pressure relief.

[0067] Specifically, the second inclined portion is configured as a second inclined surface 70 that is inclined relative to both the first direction and the second direction. It can be understood that in other embodiments, the second inclined portion is configured as two second sub-inclined surfaces that are inclined relative to both the first direction and the second direction, and the two second sub-inclined surfaces are connected to form a V-shape with an uphill section and a downhill section, so that complete pressure relief control of the exhaust mechanism 20 can be achieved through movement in both directions (reciprocating direction in the first direction).

[0068] In the above two embodiments, for the convenience of setting, the second inclined surface 70 of the second actuating structure is formed on the pressure relief mechanism 60, and the second matching member 80 (rolling member or sliding member) is assembled on the end of the exhaust mechanism 20 that abuts against the pressure relief mechanism 60, so that when the pressure relief mechanism 60 moves relative to the inner cover 12, a component force of the second inclined surface 70 of the second actuating structure acting on the second matching member 80 will drive the second matching member 80 to drive the exhaust mechanism 20 to move relative to the inner cover 12 along the second direction to achieve complete pressure relief. It can be understood that in another embodiment, the second inclined surface 70 of the second actuating structure can also be opened on the exhaust mechanism 20, and the second matching member 80 is assembled on the pressure relief mechanism 60, which is not limited here.

[0069] In another embodiment, the difference from the above two embodiments is that the second actuating structure also includes a roller, which is arranged on the second inclined portion, and the roller of the second actuating structure is in contact with the second mating piece 8, and when the pressure relief mechanism 60 moves along the first direction relative to the inner cover 12, a component force of the roller of the second actuating structure acting on the second mating piece 80 will drive the second mating piece 80 to drive the sealing piece 212 to compress the elastic piece 22 and then deform, so as to achieve complete pressure relief in the cooking space.

[0070] In a specific embodiment, the second inclined surface 70 is disposed on the pressure relief mechanism 60, and specifically, the second matching member 80 is disposed on the exhaust mechanism 20. Figure 8 and Fig. 9Specifically, the second matching member 80 includes a second cylinder 81 and a second extension column 82 extending from the outer wall of the second cylinder 81. The second cylinder 81 is assembled in the fixing seat 211 and one end is fixedly connected to the sealing member 212. One end of the elastic member 22 is fixedly sleeved in the second cylinder 81, that is, one end of the elastic member 22 is fixedly connected to the sealing member 212 through the second cylinder 81. The other end of the second cylinder 81 is sleeved in the first cylinder 51. The first cylinder 51 is provided with a guide groove 53 along the axial direction. The first extension column 52 can move in the guide groove 53. The second extension column 82 passes through the fixing seat 211, and the second inclined surface 70 cooperates with the protruding end of the second extension column 82. In this way, when the pressure relief mechanism 60 moves relative to the inner cover 12 along the first direction, the exhaust mechanism 20 can be completely separated from the exhaust port 111 under the cooperation of the second inclined surface 70 and the second extension column 82, so as to achieve complete pressure relief in the cooking space.

[0071] Continue reading Figure 6 and Figure 7 Specifically, in order to ensure that pressure regulation and pressure relief do not interfere with each other, the second inclined surface 70 and the first inclined surface 40 are staggered along the second direction. In this way, when the pressure regulating mechanism 30 cooperates with the first extension column 52 to adjust the pre-pressure of the exhaust mechanism 20 acting on the exhaust port 111 through the first inclined surface 40, the second inclined surface 70 and the second extension column 82 are not matched, and the pressure relief structure 60 will not act on the exhaust mechanism 20. When the pressure relief mechanism 60 cooperates with the second inclined surface 70 and the second extension column 82 to relieve pressure, the first inclined surface 40 and the first extension column 52 are not matched, and the pressure regulating mechanism 30 will not act on the exhaust mechanism 20.

[0072] In one embodiment, the cover body 100 also includes a mating mechanism 90, which can reciprocate in a first direction relative to the main body 10. The mating mechanism 90 cooperates with the pressure relief mechanism 60 to make the exhaust mechanism 20 move in a second direction relative to the main body 10, so that the exhaust mechanism 20 fully opens the exhaust port 111.

[0073] Specifically, the matching mechanism 90 is integrally arranged between the pressure regulating mechanism 30 and the pressure relief mechanism 60, and a plane 91 is formed on the matching mechanism 90. The plane 91 extends along the first direction and is arranged on the first inclined surface 40. The plane 91 is arranged opposite to the second inclined surface 70 along the second direction. When the second inclined surface 70 is matched with the second matching piece 80, the first extension column 52 is always in contact with the plane 91. At this time, the pressure regulating mechanism 30 does not play a pressure regulating role, and the second inclined surface 70 applies an upward force to the second matching piece 80. At this time, the elastic piece 22 is compressed upward, and the exhaust mechanism 20 fully opens the exhaust port 111 to achieve complete pressure relief of the cooking space.

[0074] It is conceivable that in some other embodiments, the cover body 100 may also omit the matching mechanism 90. In this case, the pressure relief mechanism 60 may also enable the exhaust mechanism 20 to open the exhaust port 111 to achieve complete pressure relief, which is not limited here.

[0075] The cover body 100 further includes a driving member, which is connected to the pressure regulating mechanism 30 and the pressure relief mechanism 60 and is used to drive the pressure regulating mechanism 30 and the pressure relief mechanism 60 to perform reciprocating motion along a first direction.

[0076] Specifically, the driving member is a stepper motor. In other embodiments, the driving member may also be a cylinder, as long as it can drive the pressure regulating mechanism 30 and the pressure relief mechanism 60 to reciprocate along the first direction, and the type of the driving member is not limited here.

[0077] An embodiment of the present invention further provides a cover 100 included in the above cooking utensil.

[0078] The working principle of the cover 100 and the cooking utensil provided by the embodiment of the present invention is as follows:

[0079] See also Figure 7 When it is necessary to adjust the constant cooking pressure in the cooking space, the driving member drives the pressure regulating mechanism 30 to reciprocate along the first direction, the first inclined surface 40 cooperates with the first extension column 52, the first cylinder 51 and the second cylinder 81 produce relative movement, and the elastic member 22 is compressed downward to different degrees, thereby adjusting the pre-compression elastic force of the exhaust mechanism 20 acting on the exhaust port 111 to adjust the constant cooking pressure in the cooking space.

[0080] When it is necessary to achieve complete pressure relief in the cooking space, the driving member drives the pressure relief mechanism 60 to move in the first direction, the second inclined surface 70 cooperates with the second extension column 82, the first cylinder 51 and the second cylinder 81 produce relative movement, and the elastic member 22 is compressed upward, so that the exhaust mechanism 20 is completely separated from the exhaust port 111 to achieve complete pressure relief in the cooking space.

[0081] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0082] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be subject to the attached claims.
