Technical Field

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

[0002] Currently, there are many types of cooking appliances, including rice cookers, pressure cookers, and electric stew pots. For example, pressure cookers are widely used in household applications. Whether they are heated by an open flame or electrically heated, pressure cookers can be used to cook food in a pressurized state, such as for clear soups, or in a non-pressurized state, such as for thick soups, to better meet people's needs.

[0003] In related art, to facilitate switching between pressurized and depressurized states, the upper cover of a pressure cooker is equipped with a pressure switching structure to raise or lower the pressure regulating valve.

One detection component of the detection device moves with the movement of the pressure switching structure, while the other detection component is relatively fixed to the upper cover. The first detection component generally moves in the vertical direction. Due to the limited thickness of the upper cover, the travel distance between the first and second detection components is limited, making it prone to sensing failure. Utility Model Content

[0031] In the upper cover of the embodiment of the present application, when the user needs to switch the cooking chamber between pressurized and depressurized, the user drives the driving member to move relative to the cover. During this movement, the driving member simultaneously drives the lever and the push rod to rotate relative to the cover. When the driving member pushes one end of the lever downward, the other end of the lever rises upward, thereby enabling the lever to lift the pressure regulating valve. The pressure regulating valve then moves away from the pressure relief port. At this time, the first detection member mounted on the other end of the push rod can move closer to or farther from the second detection member mounted on the cover, thereby detecting that the cooking chamber has switched from pressurized to depressurized. When the driving member is driven again, the driving member releases the downward pressure on the lever, and the other end of the lever descends under its own weight or the weight of the pressure regulating valve. The pressure regulating valve then blocks the pressure relief port. At this time, the first detection member mounted on the other end of the push rod can move closer to or farther from the second detection member mounted on the cover, thereby detecting that the cooking chamber has switched from depressurized to pressurized.

[0032] Since the push rod of the embodiment of the present application swings in the circumferential direction of the cover body, and the cover body has a large stroke in the circumferential direction, the present application designs the push rod to swing in the circumferential direction of the cover body, thereby increasing the stroke between the first detection member and the second detection member, thereby avoiding detection failure of the detection component.

[0052] 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

[0053] 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.

[0054] 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.

[0055] 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.

[0056] 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.

[0057] 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.

[0058] There are many different types of cooking appliances, including rice cookers, pressure cookers, and electric stew pots. Take pressure cookers, for example. They utilize steam pressure to speed up the cooking process by sealing the air inside the pot, preventing steam from escaping. This creates a pressure higher than atmospheric pressure within the pot. This increased pressure raises the boiling point of water, allowing food to cook at a higher temperature, thus shortening cooking time while preserving nutrients and flavor.

[0059] Regardless of whether it is a pressure cooker used with an open flame or an electrically heated pressure cooker, by cooking in a pressurized state, for example, a clear soup mode can be achieved, and by cooking in a non-pressurized state, for example, a thick soup mode can be achieved, which can better meet people's usage needs.

[0060] In related art, to facilitate switching between pressurized and depressurized states, the upper cover of a pressure cooker is equipped with a pressure switching structure to raise or lower the pressure regulating valve. To facilitate identification of the state to which the pressure switching structure has switched, the pressure cooker is also equipped with a detection device. One detection component of the detection device moves with the movement of the pressure switching structure, while the other detection component is relatively fixed to the upper cover. The first detection component generally moves in the vertical direction. Due to the limited thickness of the upper cover, the travel distance between the first and second detection components is limited, making it prone to sensing failure.

[0061] Based on this, an embodiment of the present application provides an upper cover 10 and a cooking utensil 1, aiming to improve the problem in the related art that the detection device of the cooking utensil 1 for detecting the pressurized state and the non-pressurized state is prone to failure.

[0062] In the embodiment of the present application, the cooking appliance 1 may include one of a pressure cooker, an electric rice cooker, and an electric stew pot. The embodiment does not limit the specific type of the cooking appliance 1. For the sake of convenience, the cooking appliance 1 in the following embodiment is a pressure cooker, and the advantages of the cooking appliance 1 of the present application are described in detail.

[0063] For example, see Pressure Cooker Figure 1 and Figure 2 The pot body 20 usually includes an outer pot 21 and an inner pot 22. The inner pot 22 is used to directly hold food and is detachably installed in the outer pot 21, which is convenient for users to clean and replace. It can also prevent users from directly contacting the heated surface of the inner pot 22, reducing the risk of scalding; the outer pot 21 can serve as an insulation layer to reduce heat loss, so that the food in the inner pot 22 can be heated more quickly and evenly.

[0064] See also Figures 1 to 5The upper cover 10 is openably and closably mounted on the pot body 20 and cooperates with the pot body 20 to form a cooking chamber 130. The 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 140 that communicates with the cooking chamber 130. The pressure regulating valve 200 is movably mounted on the cover body 100 to open or close the pressure relief vent 140. When pressure cooking is required, the pressure regulating valve 200 blocks the pressure relief vent 140, preventing the steam in the cooking chamber 130 from being released freely. This increases the boiling point of the water, thereby raising the cooking temperature and pressure and accelerating the cooking process. It is understood that once the pressure inside the cooking chamber 130 exceeds the safe range, the pressure regulating valve 200 will be lifted by the steam pressure, serving as a second line of defense to forcibly release the pressure and prevent accidents. When pressure-free cooking is required, the pressure regulating valve 200 is at least partially separated from the pressure relief port 140 so that the pressure relief port 140 can communicate with the outside and the cooking cavity 130, thereby balancing the air pressure in the cooking cavity 130 and the outside.

[0065] As will be appreciated, the lid 100 may be provided with an exhaust pipe, which forms the pressure relief port 140 communicating with the cooking chamber 130, and the pressure regulating valve 200 may be sleeved onto the exhaust pipe. This allows the pressure regulating valve 200 to be stably secured to the pressure relief port 140, thereby maintaining a stable pressurized state in the cooking chamber 130.

[0066] See also Figure 4 and Figure 5 The pressure switching structure 300 includes a driving member 310 and a lever 320. The driving member 310 is movably connected to the cover 100 and is in transmission connection with one end of the lever 320. The lever 320 is rotatably connected to the cover 100, and the end of the lever 320 away from the driving member 310 abuts the pressure regulating valve 200. Specifically, to switch the cooking chamber 130 between pressurized and depressurized, the user drives the driving member 310 relative to the cover 100. During this movement, the driving member 310 simultaneously pushes one end of the lever 320 downward, causing the other end of the lever 320 to rise upward. This allows the lever 320 to lift the pressure regulating valve 200, allowing the pressure regulating valve 200 to move away from the pressure relief port 140, thereby switching the cooking chamber 130 from pressurized to depressurized. When the driver 310 is driven 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 140, thereby switching the cooking chamber 130 from a pressure-free state to a pressurized state. The pressure switching structure 300 of the embodiment of the present application facilitates switching between pressurized and pressure-free states of the pressure cooker during cooking, allowing users to easily select different cooking modes.

[0067] See also Figure 2 The detection assembly 400 includes a first detection member 410, a push rod 420 and a second detection member 430. The push rod 420 is rotatably connected to the cover body 100 and is transmission-connected to the driving member 310. The first detection member 410 is mounted on one end of the push rod 420 away from the driving member 310, and the second detection member 430 is mounted on the cover body 100 or the pot body 20. Specifically, when the user drives the driving member 310 to move relative to the cover body 100, and the driving member 310 drives one end of the lever 320 to press down, the driving member 310 can also drive the push rod 420 to swing relative to the cover body 100. At this time, the first detection member 410 mounted on the other end of the push rod 420 can approach or move away from the second detection member 430 mounted on the cover body 100, thereby being able to identify that the cooking cavity 130 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 be pressed down, and the driving member 310 drives the push 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 push 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 130 has switched from a non-pressure state to a pressurized state.

[0068] For the embodiment in which the second detection member 430 is installed on the pot body 20, the detection assembly 400 can detect a signal only when the upper cover 10 and the pot body 20 are fastened together, thereby improving the use effect of the product.

[0069] It should be noted that detection assembly 400 can include any one of a photoelectric switch, a reed proximity switch, or a Hall effect proximity switch. A 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 a reed proximity switch and a Hall effect proximity switch can function as position sensors. The above-described detection assembly 400 is not specifically limited. The following description will use the example of a detection assembly 400 including a reed proximity switch as an example.

[0070] Specifically, the first detecting member 410 can be one of a reed switch and a magnet, and the second detecting member 430 can be the other of the reed switch and the magnet. For example, the first detecting member 410 is a magnet, and the second detecting member 430 is a reed switch. When the magnet and the reed switch move closer or further away from each other, the reed switch generates a corresponding open / close signal.

[0071] Based on the upper cover 10 of the embodiment of the present application, when the driving member 310 is subjected to force to move relative to the cover body 100, the driving member 310 can simultaneously drive the lever 320 and the push rod 420 to rotate relative to the cover body 100, thereby respectively lifting the pressure regulating valve 200 and driving the first detection member 410 to move along the circumference of the cover body 100 to move closer to or away from the second detection member 430. For example, when the driving member 310 drives the lever 320 downward, the pressure regulating valve 200 is lifted, and the driving member 310 simultaneously drives the first detection member 410 on the push rod 420 away from the second detection member 430, thereby being able to identify that the cooking chamber 130 has switched to a pressure-free state. The driving member 310 moves away from the lever 320, thereby releasing the force on the lever 320. The pressure regulating valve 200 blocks the pressure relief port 120 under the action of gravity. At this time, the driving member 310 also drives the first detection member 410 on the push rod 420 to approach the second detection member 430, thereby being able to identify that the cooking cavity 130 has switched to a pressurized state.

[0072] It should be noted that the push rod 420 and the cover body 100 are rotatably connected via a rotating shaft, and the axial direction of the transmission shaft extends in the vertical direction. When the driving member 310 applies a force to one end of the push rod 420, the push rod 420 will swing in the circumferential direction of the cover body 100. It is understandable that the cover body 100 has a large stroke in the circumferential direction. By designing the push rod 420 to swing in the circumferential direction of the cover body 100, the present application can increase the stroke between the first detection member 410 and the second detection member 430, thereby avoiding the situation where the detection assembly 400 fails to detect.

[0073] In some embodiments, please refer to Figure 9 The cover body 100 includes an inner cover assembly 110 and a surface cover 120. The surface cover 120 is arranged on the outside of the inner cover assembly 110, and is enclosed with the inner cover 111 and the pot cover 112 to form an installation space 160. The surface cover 120 is provided with a first avoidance hole corresponding to the pressure relief port 140. The lever 320 is installed in the installation space 160, and the driving member 310 is slidably installed on the top surface of the surface cover 120, and is at least partially located in the installation space 160 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.

[0074] For further information, see Figure 6 、 Figure 7 and Figure 9The 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 140. The inner cover 111 is fixedly connected to the surface cover 120, so that the inner cover 111, the pot cover 112 and the surface cover 120 together define an installation space 160. 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. Among them, the lever 320 is rotatably connected to the surface cover 120. For details, please refer to Figure 13 The inner wall surface of the cover 120 is provided with a fixing groove, and the middle part of the lever 320 has a cantilever 321. The cantilever 321 is inserted into the fixing groove, so that the opposite sides of the lever 320 can swing with the cantilever 321 as the axis.

[0075] In some embodiments, please refer again to Figure 6 、 Figure 7 and Figure 9 The push 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 push rod 420 and the inner cover 111, the push rod 420 and the first detection member 410 are swung within the escape groove 1111. This optimizes the utilization of the internal space of the upper cover 10, making the entire structure more compact and reducing unnecessary volume and weight. In addition, because the push rod 420 and the first detection member 410 are swung within the escape groove 1111, they can move freely without interfering with other components.

[0076] See also Figure 9 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. A relief opening is provided on the cover 120, connecting the mounting space 160 and the mounting groove 121. The end of the lever 320 distal from the driver 310 is positioned 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 distal from the driver 310. During the movement of the lever 320, the seal 600 maintains a seal around the relief opening. This arrangement allows the seal 600 to seal the mounting space 160. Specifically, when the pressure regulating valve 200 is lifted, a large amount of steam is discharged from the exhaust pipe. The seal 600 maintains a seal around the relief opening, preventing the steam from flowing back into the mounting space 160. This prevents impurities such as dust and moisture from entering the mounting space 160 through the relief opening, thereby extending the service life of components and ensuring safe operation of the device.

[0077] In order to facilitate the installation of the openable and closable upper cover 10 on the pot body 20, the upper cover 10 of the embodiment of the present application also includes a handle assembly 500. When the upper cover 10 needs to be opened, the user can grab the handle assembly 500 to remove the upper cover 10 from the pot body 20.

[0078] For further information, see Figure 10 The handle assembly 500 includes a handle 510, a drive rod 520 and a reset member 530. The handle 510 is mounted on the face cover 120, wherein the handle 510 and the face cover 120 can be connected by one or more of a snap connection and a screw connection. The drive rod 520 passes through the handle 510 and the face cover 120 and can be slidably arranged in the vertical direction relative to the handle 510. One end of the reset member 530 is connected to the handle 510 and the other end is connected to the drive rod 520 to drive the drive rod 520 to have an upward force. The reset member 530 can be in the form of a spring, a tension spring, etc.

[0079] Specifically, when the user presses the top of the drive rod 520, the bottom of the drive rod 520 pushes down on one end of the lever 320 away from the pressure regulating valve 200, causing the other end of the lever 320 to lift the pressure regulating valve 200. With this arrangement, the user can use the handle assembly 500 to achieve a point-by-point pressure relief mode within the cooking appliance 1, and can also use the pressure switching structure 300 to achieve a continuous pressure relief mode within the cooking appliance 1. During the cooking process, if the internal pressure of the cooking appliance 1 is too high, it may pose a safety hazard. The point-by-point pressure relief mode allows the user to 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 within the cooking chamber 130 according to cooking needs, ensuring the safety of the cooking process.

[0080] Furthermore, different ingredients and cooking methods require different cooking pressures. The spot pressure release mode allows users to precisely control the pressure changes within cooking chamber 130, 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 suitable for cooking processes that require maintaining a lower pressure for an extended period, such as porridge or stewing soup.

[0081] 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.

[0082] There are many forms of the driving member 310 being movably connected to the cover body 100 and being able to drive the lever 320 and the push rod 420 to rotate, which are described in detail below.

[0083] The driving member 310 includes a main body 311 and a pressing portion 312, which are connected to each other. The main body 311 is slidably connected to the cover 100, and the pressing portion 312 has a pressing surface 312a that slidably engages with the lever 320. The sliding direction of the pressing portion 312 can be the same as or intersects with the extension direction of the lever 320. To improve the sliding stability of the driving member 310 on the cover 100, the cover 100 is provided with a slide groove 150, and the main body 311 is slidably mounted in the slide groove 150.

[0084] In the solution where the sliding direction of the pressing portion 312 intersects with the extending direction of the lever 320, please refer to Figures 8 to 13 The driving member 310 moves to the side of the lever 320 to align with the lever 320. When the driving member 310 is above the lever 320, the pressing surface 312a of the pressing portion 312 abuts against the lever 320. The pressing surface 312a includes a guide section 3121 and a pressing section 3122 connected to each other. The guide section 3121 is connected to the side of the pressing section 3122 close to the lever 320. The guide section 3121 is inclined from bottom to top in a direction away from the pressing section 3122. The pressing section 3122 extends horizontally.

[0085] Specifically, in the process of the driving member 310 moving toward the lever 320, the guide section 3121 can guide the lever 320 to be pressed down along the surface of the guide section 3121. When the lever 320 is located at the pressing section 3122, the pressing section 3122 can firmly abut the lever 320, so that the cooking utensil 1 can continuously and smoothly release pressure.

[0086] In this embodiment, the main body 311 can be annular or arcuate, wherein the shape of the slide groove 150 is adapted to the shape of the main body 311. In the case of annular main body 311, an annular slide groove 150 is provided on the cover 120. The main body 311 can apply a downward force to the lever 320 and release the downward force on the lever 320 within the slide groove 150. Furthermore, a rotation shaft is provided at the bottom of the main body 311. The rotation shaft includes a shaft body and a limiter. The shaft body passes through the cover 120, the limiter abuts the bottom surface of the cover 120, and the main body 311 abuts the top surface of the cover 120. Thus, the main body 311 can be fixed to the cover 120 and can rotate relative to the cover 120.

[0087] Of course, in order to improve the stability of the main body 311 rotating relative to the cover 120 , the bottom of the main body 311 has a plurality of rotation axes, and the plurality of rotation axes are arranged at intervals at the bottom of the main body 311 .

[0088] Furthermore, the chute 150 is arranged around the center of the cover 100. It is understood that, generally, the handle assembly 500 is installed at the center of the cover 100, and the chute 150 of the present application can be arranged around the handle assembly 500, thereby making reasonable use of the space on the top surface of the cover 120.

[0089] In the solution where the sliding direction of the driving member 310 is the same as the extending direction of the lever 320, see Figures 1 to 3 The main body 311 and the pressing portion 312 can be arranged in a strip shape, and the slide groove 150 can also be arranged in a strip shape and extend outward in a direction away from the center of the cover body 100. In other words, the main body 311 moves in the extension direction of the lever 320, so that the pressing surface 312a abuts the lever 320 at a position relatively close to or relatively away from the connection between the lever 320 and the cover 120, thereby changing the swing angle of the lever 320 relative to the cover 120, thereby pressing down one end of the lever 320, so that the other end of the lever 320 can lift the pressure regulating valve 200.

[0090] The main body 311 and the pressing portion 312 in the above two embodiments may both be an integral structure and may be integrally formed by injection molding, which results in higher processing efficiency.

[0091] To enhance the stability of the contact between the driver 310 and the lever 320, an upwardly tilted pressing portion 322 is formed on the end of the lever 320 facing away from the pressure-regulating valve 200, with the lower pressing portion 312 contacting the pressing portion 322. In some embodiments, the pressing portion 322 extends upward toward the pressure-regulating valve 200. Of course, the pressing portion 322 can also extend upward away from the pressure-regulating valve 200. In embodiments where the driver 310 moves laterally to align with the lever 320, the tilt of the guide section 3121 can be further adjusted.

[0092] Please refer to Figures 1 to 5 In the embodiment where the main body 311 is arranged in a strip shape, the cover 100 may include a mounting base 170. The mounting base 170 is mounted on the top of the cover 120 and defines a slide groove 150 together with the cover 120. The main body 311 slides in the slide groove 150. This facilitates the installation of the driving member 310 and makes it easier for the user to drive the driving member 310 to slide.

[0093] One of the main body 311 and the push rod 420 is provided with a driving shaft 3111, and the other is provided with a driving slot 421, and the driving shaft 3111 can be movably inserted into the driving slot 421. Figure 11 and Figure 12For example, the main body 311 is provided with a drive shaft 3111, and the push rod 420 is provided with a drive groove 421. When the driving member 310 moves and can drive the push rod 420 to swing, the drive shaft 3111 will move within the drive groove 421. With this arrangement, when the main body 311 pushes the push rod 420 to move, the drive shaft 3111 can have a certain amount of swing space within the drive shaft 3111, thereby allowing the push rod 420 to adapt to complex working environments and movement trajectories, and thus the first detection member 410 can swing along the circumference of the cover body 100. Moreover, the drive groove 421 can prevent the main body 311 and the push rod 420 from getting stuck due to inappropriate force direction during the swinging process.

[0094] In order to facilitate the sliding of the main body 311, please refer to Figures 1 to 5 as well as Figure 8 The driving member 310 of the embodiment of the present application further includes a dial knob 313, which is connected to the main body 311 and exposed outside the cover 100. 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 turning the dial knob 313. It can be understood that in order to increase the friction between the user's finger and the dial knob 313, a protrusion or frosted portion can be provided on the outer surface of the dial knob 313. The dial knob 313 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.

[0095] In other embodiments, the driver 310 can also move vertically relative to the cover 100. In this manner, the driver 310 can also depress one end of the lever 320, thereby driving the other end of the lever 320 to lift the pressure regulating valve 200. In this embodiment, a wedge-shaped surface can be provided at the bottom of the driver 310, and a wedge-shaped surface can also be provided at the end of the push rod 420 away from the first detection member 410. The wedge-shaped surface of the driver 310 and the wedge-shaped surface of the push rod 420 can mate with each other. When the driver 310 moves vertically, the wedge-shaped surface can drive the push rod 420 to rotate circumferentially around a vertically arranged rotation axis. The present application does not limit the specific movement of the driver 310; any method that can drive the push rod 420 to rotate circumferentially relative to the cover 100 falls within the scope of protection of this application.
