Description

Technical Field

[0001] The utility model relates to the technical field of cooking equipment, in particular to an upper cover and a cooking utensil. Background Art

[0002] Currently, there are many types of cooking appliances, including rice cookers, pressure cookers, and electric stew pots. However, existing cooking appliances can only cook in either a pressurized or non-pressurized state and cannot accommodate both cooking modes. As a result, one cooking appliance cannot achieve different cooking effects on ingredients. For example, a pressure cooker typically cooks in a pressurized mode with a high cooking pressure. When stewing soup, the high pressure prevents the liquid from rolling, allowing for a clear soup. In contrast, rice cookers typically cook in a micro-pressure state. When stewing soup in an electric rice cooker, the low cooking pressure causes the soup to roll easily, making it easy to achieve a thick soup. Since current common cooking appliances cannot accommodate both cooking modes, users need to purchase multiple appliances to meet different cooking needs, increasing usage costs. In addition, multiple appliances take up a large amount of space, making them inconvenient to use. Utility Model Content

[0040] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the present invention clearer, the following part will further describe the embodiments of the present application in detail with reference to the accompanying drawings.

[0042] When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Instead, they are merely examples of devices and methods consistent with some aspects of the present invention, as detailed in the appended claims.

[0043] In the description of the present invention, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. In addition, in the description of the present invention, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships can exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used in this specification are for the purpose of describing specific embodiments only and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0045] At present, with the development of science and technology and the improvement of people's living standards, more and more cooking utensils have appeared in the kitchen to meet different cooking needs and preferences. These utensils not only improve cooking efficiency, but also enrich the taste and nutrition of food.

[0046] Pressure cookers utilize high temperatures and pressures to speed up cooking, significantly reducing cooking time. Furthermore, cooking under high pressure better preserves nutrients and flavor, enabling a thick soup mode, for example. Non-pressure cookers, due to their gentler cooking process, are more likely to preserve the original flavor and texture of ingredients, enabling a clear soup mode, for example. However, conventional cookers can only operate in one mode, requiring users to purchase different cookers, increasing costs and storage space.

[0047] Based on this, the embodiment of the present application proposes an upper cover and a cooking utensil, which enables the cooking device to switch between a pressurized state and a non-pressurized state, making it convenient for users to cook.

[0048] In the embodiments of the present application, the cooking appliance may be a pressure cooker, an electric pressure cooker, an electric stew pot, or the like. The specific type of cooking appliance is not limited in this embodiment. For the sake of convenience in describing the following content, the cooking appliance in the following embodiments is a pressure cooker, and the advantages of the cooking appliance of the present application are described in detail.

[0049] For example, a pressure cooker consists of a pot body and a lid. The pot body typically includes an outer pot and an inner pot (also called an inner pot). The inner pot is used to hold food and can be removably mounted inside the outer pot for easy cleaning and replacement. The outer pot acts as an insulation layer, reducing heat loss, allowing the food in the inner pot to heat more quickly and evenly. It also prevents users from directly contacting the heated inner pot surface, reducing the risk of burns.

[0050] The upper cover 10 can be opened and closed on the pot body and cooperates with the pot body to form a cooking cavity. Figure 1 and Figure 2The upper cover 10 includes a cover body 100, a pressure regulating valve 200, a pressure switching structure 300, and a detection assembly 400. The cover body 100 is provided with a pressure relief vent that communicates with the cooking chamber. The pressure regulating valve 200 is movably mounted on the cover body 100 to open or close the pressure relief vent. When pressure cooking is required, the pressure regulating valve 200 blocks the pressure relief vent, preventing the free release of steam within the cooking chamber. This increases the boiling point of water, thereby increasing the cooking temperature and pressure and accelerating the cooking process. It will be understood that once the pressure within the cooking chamber exceeds the set range, the pressure regulating valve 200 is lifted by the steam pressure, acting as a second line of defense to forcibly release the pressure and avoid accidents. When pressure-free cooking is required, the pressure regulating valve 200 at least partially moves away from the pressure relief vent, allowing the pressure relief vent to communicate with the outside world and the cooking chamber, thereby balancing the air pressure between the cooking chamber and the outside world.

[0051] The cover 100 may be provided with an exhaust pipe, which forms the pressure relief port connected to the cooking chamber, and the pressure regulating valve 200 is sleeved on the exhaust pipe. In this way, the pressure regulating valve 200 can be stably fixed on the pressure relief port, thereby maintaining a stable pressurized state in the cooking chamber.

[0052] See also Figure 2 The cover body 100 includes an inner cover assembly 110 and a surface cover 120. The surface cover 120 is arranged outside the inner cover assembly 110 and encloses the inner cover 111 to form an installation space. The surface cover 120 is provided with a second avoidance hole 123 corresponding to the pressure relief port. The lever 320 is installed in the installation space, and the driving member 310 is slidably mounted on the top surface of the surface cover 120, and is at least partially located in the installation space and abuts against the lever 320. In this way, the lever 320 can be installed in a hidden manner, making the entire structure look neater and more beautiful. It also prevents the user from directly contacting the lever 320 during use, thereby reducing the possibility of misoperation.

[0053] Please continue reading Figure 2 The inner cover assembly 110 includes an inner cover 111 and a pot cover 112. The pot cover 112 is fixed to the inner cover 111 and is provided with a pressure relief port. The inner cover 111 is fixedly connected to the surface cover 120. At least the inner cover 111 and the surface cover 120 jointly enclose an installation space. That is to say, in some embodiments, the installation space can be formed by the inner cover 111 and the surface cover 120. In other embodiments, the installation space can be formed by the inner cover 111, the pot cover 112 and the surface cover 120. The pot cover 112 and the inner cover 111, as well as the inner cover 111 and the surface cover 120, can be relatively fixed by means of a snap connection, a screw connection, or the like.

[0054] See also Figures 2 to 4The pressure switching structure 300 includes a driver 310 and a lever 320. The driver 310 is slidably connected to the face cover 120 and is transmission-connected to one end of the lever 320. The lever 320 is located between the face cover 120 and the inner cover assembly 110 and is rotationally connected to the face cover 120 or the inner cover assembly 110. Exemplarily, the lever 320 is rotationally connected to the face cover 120. The inner wall of the face cover 120 is provided with a fixing groove. The middle portion of the lever 320 has a cantilever. The cantilever is inserted into the fixing groove, so that the opposite sides of the lever 320 can swing about the cantilever as the axis. The end of the lever 320 away from the driver 310 abuts the pressure regulating valve 200.

[0055] Specifically, to switch the cooking chamber from pressurized to depressurized, the user moves the driver 310 relative to the lid 100. Simultaneously, the driver 310 pushes one end of the lever 320 downward, causing the other end of the lever 320 to rise. This pushes the lever 320 upward, allowing the pressure regulating valve 200 to move away from the pressure relief port, thereby switching the cooking chamber from pressurized to depressurized. When the driver 310 is moved again, the driver 310 releases the downward pressure on the lever 320, and the other end of the lever 320 descends under its own weight or the weight of the pressure regulating valve 200. The pressure regulating valve 200 then blocks the pressure relief port, switching the cooking chamber from depressurized to pressurized. The pressure switching mechanism 300 of this embodiment facilitates switching between pressurized and depressurized states in the pressure cooker during cooking, allowing users to select different cooking modes as needed.

[0056] See also Figures 2 to 4 The detection assembly 400 includes a first detection member 410, a support rod 420, and a second detection member 430. The support rod 420 is fixedly connected to the driving member 310 and is located between the surface cover 120 and the inner cover assembly 110. The first detection member 410 is mounted on the support rod 420, and the second detection member 430 is mounted on the cover body 100 or the pot body. When the user drives the driving member 310 to move relative to the cover body 100, and when the driving member 310 drives one end of the lever 320 to press down, the driving member 310 can also drive the support rod 420 to swing relative to the cover body 100. At this time, the first detection member 410 installed at the other end of the support rod 420 can approach or move away from the second detection member 430 installed on the cover body 100, thereby being able to identify that the cooking cavity has switched from a pressurized state to a non-pressurized state. When the driving member 310 is driven to move again, the driving member 310 can release the state of driving the lever 320 to press down, and the driving member 310 drives the support rod 420 to rotate relative to the cover body 100. At this time, the first detection member 410 installed at the other end of the support rod 420 can move away from or approach the second detection member 430 installed on the cover body 100, thereby being able to identify that the cooking cavity has switched from a non-pressure state to a pressure state.

[0057] It should be noted that the detection component 400 can include any one of a photoelectric switch, a reed proximity switch, or a Hall effect proximity switch. The photoelectric switch can detect the presence of an object by utilizing the obstruction or reflection of a light beam by the detected object, thereby activating a circuit via a synchronization circuit. Both the reed proximity switch and the Hall effect proximity switch can function as position sensors. The detection component 400 is not specifically limited herein.

[0058] In the embodiments of this application, please refer to Figures 5 to 9 The support rod 420 and the driver 310 are detachably fixedly connected. This facilitates forming the support rod 420 and the driver 310 and facilitating installation on the lid 100. Furthermore, depending on the type or size of the cooking utensils, the same driver 310 can be used with a support rod 420 of different lengths. In some connection arrangements, the support rod 420 is provided with a first connection hole 421, and the driver 310 is provided with a second connection hole 314. The support rod 420 is detachably fixedly connected to the driver 310 via a connector 700 that engages with the first connection hole 421 and the second connection hole 314. The connector 700 may be a threaded fastener such as a screw or bolt. This arrangement provides simple installation and excellent stability. Alternatively, the support rod 420 and the driver 310 may be snap-fitted, which requires no additional tools and simplifies installation.

[0059] For further information, please refer to Figures 5 to 9 The driving member 310 is provided with a first positioning portion, and the support rod 420 is provided with a second positioning portion. The first positioning portion and the second positioning portion are limited to improve the stability of the relative fixation of the driving member 310 and the support rod 420. The first positioning portion can be a positioning protrusion 3131, and the second positioning portion can be a positioning groove 422 adapted to the positioning protrusion. The number of positioning protrusions 3131 can be multiple. For example, the number of positioning protrusions 3131 is two. In other embodiments, it can also be three, four, etc. The number of positioning grooves 422 is set corresponding to the number of positioning protrusions 3131.

[0060] See also Figures 1 to 3 as well as Figures 5 to 8The driving member 310 includes a main body 311, a pressing portion 312, and a connecting portion 313. The pressing portion 312 and the connecting portion 313 are both connected to the main body 311. The main body 311 is slidably connected to the cover 120 and is at least partially exposed outside the cover 120 so that it can be driven by the user. The pressing portion 312 and the connecting portion 313 are both inserted between the cover 120 and the inner cover assembly 110. The pressing portion 312 has a pressing surface 3121, which is used to drive the lever 320. The connecting portion 313 is detachably fixedly connected to the support rod 420 using the above-mentioned connection method. In this way, when the user drives the main body 311 to rotate, the pressing portion 312 and the connecting portion 313 can be driven to rotate, and at the same time, the lever 320 and the support rod 420 can be driven to move.

[0061] The pressing surface 3121 includes a pressing section 3123 and a guide section 3122. The pressing section 3123 is connected to the side of the guide section 3122 away from the lever 320 and extends horizontally. Specifically, as the driving member 310 moves toward the lever 320, the guide section 3122 guides the lever 320 downward along its surface. When the lever 320 is located on the pressing section 3123, the pressing section 3123 firmly contacts the lever 320, thereby allowing the cooking appliance to continuously and smoothly release pressure.

[0062] See also Figure 2 To improve the stability of the driving member 310 sliding on the cover 120, the upper surface of the cover 120 is provided with a groove 150 and a first avoidance hole 122 connected to the groove 150. The main body 311 is slidably mounted in the groove 150, and the pressing portion 312 and the connecting portion 313 are disposed through the first avoidance hole 122 and extend between the cover 120 and the inner cover assembly 110. With this arrangement, a user can drive the main body 311 located on the upper surface of the cover 120, thereby causing the pressing portion 312 and the connecting portion 313 to rotate, thereby driving the movement of the lever 320 and the support rod 420.

[0063] Furthermore, the main body 311 is annular, and the shape of the chute 150 matches that of the main body 311. A rotation axis is provided at the bottom of the main body 311. The rotation axis includes a shaft body and a stopper. The shaft body passes through the face cover 120, the stopper abuts the lower surface of the face cover 120, and the main body 311 abuts the upper surface of the face cover 120. Thus, the main body 311 can be fixed to the face cover 120 and can rotate relative to the face cover 120. In this way, the main body 311 can cover the first avoidance hole 122, preventing external impurities or dust from entering the installation space between the face cover 120 and the inner cover assembly 110 through the avoidance hole.

[0064] It can be understood that when the main body 311 is arranged in a ring shape, it can also be arranged in a strip shape, and have an arc structure or a straight line shape. In this case, the shape of the slide groove 150 can be adapted to the shape of the main body 311, and the slide groove 150 can also be arranged on the top surface of the face cover 120, that is, formed by the depression of the top surface of the face cover 120.

[0065] It is understood that in order to improve the stability of the rotation of the main body 311 relative to the cover 120, the bottom of the main body 311 has multiple rotation axes, and the multiple rotation axes are spaced apart at the bottom of the main body 311. The number of the first avoidance holes 122 is also multiple. It is understood that when the main body 311 is an arc-shaped structure or a straight line, the first avoidance hole 122 is a strip hole that does not surround the entire cover body of the main body 311. This can facilitate the insertion of the pressing portion 312 and the connecting portion 313 into the installation space, and can also facilitate the insertion of the rotation axis into the first avoidance hole 122 for installation and fixation, so that the main body 311 can rotate stably. It should be noted that the rotation axis includes a shaft body and a limit portion. After the rotation axis is installed, the shaft body will pass through the first avoidance hole 122, the limit portion abuts the bottom surface of the cover 120, and the main body 311 abuts the top surface of the cover 120, so that the main body 311 can be fixed on the cover 120 and can rotate relative to the cover 120. Of course, in order to improve the stability of the main body 311 in rotating relative to the cover 120, the bottom of the main body 311 has multiple rotation axes, and the multiple rotation axes are spaced apart at the bottom of the main body 311. The number of the first avoidance holes 122 can be set corresponding to the number of the rotation axes.

[0066] The chute 150 is arranged around the center of the cover 100. Generally, the handle assembly 500 is installed at the center of the cover 100, but the chute 150 of the present application can be arranged around the handle assembly 500, so that the space on the top surface of the cover 120 can be reasonably utilized.

[0067] In order to facilitate the sliding of the main body 311, the driving member 310 of the embodiment of the present application also includes a dial knob 315. The dial knob 315 is connected to the main body 311 and is exposed outside the cover 100. The main body 311 is completely embedded in the slide groove 150. In this way, the main body 311, the lever 320 and other components can be installed in a hidden manner, and the main body 311 can be driven to slide relative to the cover 100 by simply dialing the dial knob 315. It can be understood that in order to increase the friction between the user's finger and the dial knob 315, a protrusion or frosted portion can be provided on the outer surface of the dial knob 315. The dial knob 315 and the main body 311 can be integrally formed or separately provided, and then installed as a whole through various forms such as snap connection, screw connection, and bonding.

[0068] Of course, when the knob 315 is provided, the sliding connection between the main body 311 and the cover 120 in this application can also be to slide the main body 311 to the inner surface of the cover 120, that is, the slide groove 150 can be set on the inner surface of the cover 120.

[0069] In some embodiments, the support rod 420 is rotatably connected to the inner cover 111, and the inner cover 111 is provided with an escape groove 1111. During the relative rotation of the support rod 420 and the inner cover 111, the support rod 420 and the first detection member 410 are swung within the escape groove 1111. In this way, the utilization of the internal space of the upper cover 10 can be optimized, making the entire structure more compact and reducing unnecessary volume and weight. In addition, because the support rod 420 and the first detection member 410 are swung within the escape groove 1111, they can move freely without interfering with other components.

[0070] See also Figure 2 The top surface of the cover 120 is provided with a mounting groove 121, which is upwardly open and is used to accommodate at least a portion of the pressure regulating valve 200. The cover 120 is provided with a relief opening that connects the mounting space and the mounting groove 121. The end of the lever 320 away from the driver 310 is inserted through the relief opening and extends into the bottom of the pressure regulating valve 200. The upper cover 10 also includes a seal 600, which is mounted on the end of the lever 320 away from the driver 310. During the movement of the lever 320, the seal 600 always seals the relief opening. This arrangement allows the seal 600 to seal the mounting space. Specifically, when the pressure regulating valve 200 is lifted, a large amount of steam is discharged from the exhaust pipe. The seal 600 always seals the relief opening, preventing the steam from flowing back into the mounting space. Furthermore, it prevents impurities such as dust and moisture from entering the mounting space through the relief opening, thereby improving the service life of the components and ensuring the safe operation of the equipment.

[0071] For the upper cover 10 described above and below, the detection component 400 and the pressure regulating valve 200 are arranged radially away from each other along the cover body 100, so that the lever 320 has a longer lever arm, which can effectively increase the height of the lever 320 to lift the pressure regulating valve 200, thereby ensuring the stability of pressure regulation.

[0072] The handle assembly 500 includes a handle, a drive rod, and a reset member. The handle is mounted on the cover 120, wherein the handle and the cover 120 can be connected by one or more of a snap-fit connection and a screw connection. The drive rod passes through the handle and the cover 120 and can slide vertically relative to the handle. The reset member is connected to the handle at one end and to the drive rod at the other end, thereby driving the drive rod upward. The reset member can be in the form of a spring, a tension spring, or the like.

[0073] Specifically, when the user presses the top of the drive rod, the bottom of the drive rod pushes down the lever 320 away from one end of the pressure regulating valve 200, so that the other end of the lever 320 lifts the pressure regulating valve 200. With this arrangement, the user can use the handle assembly 500 to achieve a point-spray pressure relief mode for the cooking appliance, and can also use the pressure switching structure 300 to achieve a continuous pressure relief mode for the cooking appliance. During the cooking process, if the internal pressure of the cooking appliance is too high, it may pose a safety hazard. Through the point-spray pressure relief mode, the user can gradually release excessive pressure, avoiding burns or equipment damage caused by the sudden release of large amounts of steam or gas. The continuous pressure relief mode allows the user to continuously and steadily reduce the pressure in the cooking chamber according to cooking needs, ensuring the safety of the cooking process.

[0074] Furthermore, different ingredients and cooking methods require different cooking pressures. The spot pressure release mode allows users to precisely control the pressure changes within the cooking chamber, optimizing cooking results. For example, when stewing meat, gradually releasing pressure can make the meat more tender and juicy. The continuous pressure release mode is ideal for cooking processes that require maintaining lower pressure for longer periods, such as porridge or stewing soup.
