[0052] Existing cooking appliances, including a pot body and a lid assembly, typically include a lid body and a cover plate located under the lid body. The lid assembly also usually incorporates multiple components (such as venting elements, detection elements like temperature or pressure sensors, and locking elements). However, existing cover plates require a dedicated mounting area for each component. Each mounting area needs corresponding through holes to accommodate the installation and connection of these components, resulting in a complex appearance for the cover plate. This also makes it easy for dirt and grime to accumulate in the gaps between the through holes, hindering cleaning.

[0053] Please see Figure 1 , Figure 2 as well as Figure 5 This utility model proposes a pot lid assembly 100 for use in cooking appliances 200, such as pressure cookers, rice cookers, cooking machines, etc. It is used to cover the pot body 6 of the cooking appliance 200 and includes a pot lid body 1 and a lid plate 2. The pot lid body 1 has a first side and a second side facing each other. The first side of the pot lid body 1 is positioned facing the pot body 6. The lid plate 2 is installed on the first side of the pot lid body 1 and has a mounting area 21 with a steam vent 22. A mounting part 23 is installed on the side of the lid plate 2 facing the pot lid body 1. The mounting part 23 cooperates with the mounting area 21 to jointly enclose a mounting cavity 24. The pot lid assembly 100 also includes multiple components 3, which are installed on the mounting part 23 and can communicate and / or contact with the steam in the mounting cavity 24.

[0054] The technical solution provided by this utility model connects the first side of the pot lid body 1 to the inside of the pot body 6, allowing multiple components 3 mounted on the cover plate 2 on the first side of the pot lid body 1 to come into steam contact and perform their functions. The cover plate 2 has a mounting area 21 with a steam passage hole 22. The mounting area 21 and the mounting part 23 form a mounting cavity 24. Steam enters the mounting cavity 24 through the steam passage hole 22 and comes into contact with the multiple components 3 mounted on the mounting part 23. This arrangement allows multiple components 3 to share a single mounting area 21, reducing the number of mounting areas 21 and the gaps in the steam passage holes 22 that need to be cleaned, thus reducing the difficulty of cleaning and making the cleaning work more convenient.

[0055] It is understood that the shape of the lid body 1 in this application can be circular, square, rectangular, or adapted to the outer edge of the upper part of the pot body 6 to ensure a sealed connection between the two and prevent steam from escaping when the pot body 6 is heated. Furthermore, the lid body 1 can also protrude from the side away from the pot body 6 to form a dome or hemispherical shape. This allows it to withstand greater steam pressure when used in pressure cookers, reducing the risk of damage to the lid body 1 and extending its service life. Similarly, the shape of the cover plate 2 can be selected from the same range as the lid body 1; they can be identical or different, which will not be elaborated further here.

[0056] It is understood that the connection between the lid body 1 and the pot body 6 in this application can be a screw-on connection (achieving a seal by rotating and screwing the lid body 1 onto the pot body 6), a snap-on connection (using several fixed snaps on the outer periphery of the lid body 1 to fasten to the upper outer edge of the pot body 6), a locking connection (the lid body 1 and the pot body 6 are respectively provided with protrusions and grooves; by pressing down and twisting the lid body 1 at a certain angle, the protrusions are inserted into the grooves to achieve locking, thereby connecting the lid body 1 and the pot body 6), and a threaded connection (the threads on the lid body 1 and the threads on the pot body 6 are screwed together and connected by rotating the lid body 1 to the pot body 6). The above are some examples; the specific selection can be adjusted according to different cooking needs and application scenarios. This application does not impose any special limitations here, as long as the lid body 1 can achieve a sealed connection with the pot body 6 to avoid steam leakage, heat waste, and reduced pressure retention.

[0057] In one embodiment, a sealing element 26 is provided at the contact point between the cover plate 2 and the upper edge of the pot body 6.

[0058] Understandably, the seal 26 can directly contact the pot body 6 to prevent liquid and gas inside the pot body 6 from leaking out from the connection point. At the same time, the material of the seal 26 should be made of a material that is high-temperature resistant, wear-resistant, corrosion-resistant, and has good elasticity, such as silicone or rubber. These materials can remain stable under high temperature and high pressure environments, ensuring the durability of the sealing effect.

[0059] It is worth mentioning that the sealing element 26 can be fixed or movable at the contact point between the cover plate 2 and the pot body 6. When the sealing element 26 is fixed to the cover plate 2, it can make it fit tightly between the cover plate 2 and the pot body 6, forming an effective seal. When the sealing element 26 is movable to the cover plate 2, it can be easily disassembled and installed, which is conducive to cleaning and replacement, thereby improving the convenience and maintainability of the pot lid.

[0060] It is understood that the shape of the steam passage 22 in this application can be circular (easy to manufacture and can effectively disperse steam flow), elliptical (provides a larger opening area, enabling a larger steam flow rate), elongated (controls the steam discharge direction), polygonal, or irregular, and different effects can be provided by designing it into a specific shape.

[0061] It is important to note that the diameter of the steam passage 22 needs to be moderate. It must not only ensure sufficient steam flow but also prevent excessive steam velocity from causing food to splash or over-boil. Ventilation efficiency must also be considered, and the shape of the steam passage 22 should facilitate cleaning to prevent food residue from clogging the passage and affecting ventilation efficiency.

[0062] It is understandable that the mounting part 23 can be arched to one side of the pot lid body 1, so that the mounting part 23 forms the mounting cavity 24 on the side facing the lid plate 2. With this configuration, the side of the lid plate 2 facing the pot body 6 does not need to have a complex concave and convex structure to accommodate the components 3, which makes the structure of the lid plate 2 flatter and smoother, reducing the accumulation of dirt and the difficulty of cleaning.

[0063] It is understood that the multiple components 3 in this application refer to a valve body that can directly communicate with steam. Under certain conditions, the valve body can communicate with the steam in the mounting cavity 24 in an active or passive manner, allowing the steam to overflow into the external environment through the valve body, reducing the pressure inside the pot body 6 and keeping it within a safe pressure range. It also includes detection elements that can directly or indirectly establish a connection with the steam in the mounting cavity 24. These detection elements (including but not limited to pressure sensors—directly measuring the pressure of the steam inside the pot, temperature sensors—measuring the temperature of the steam inside the pot, humidity sensors—measuring the moisture content in the steam, and flow sensors—monitoring the flow of steam) can detect the physical parameters of the steam in the mounting cavity 24 to provide feedback on the current physical state of the steam, thereby ensuring the safe operation and cooking effect of the cooking appliance 200. The locking device can contact the steam in the mounting cavity 24. The pressure of the steam in the mounting cavity 24 pushes the locking device to lock it between the lid body 1 and the pot body 6. Before the pressure inside the pot body 6 drops to a certain value, the lid cannot separate from the pot body 6, further improving the safety of the lid.

[0064] Please see Figure 3 and Figure 4 In one embodiment, the lid assembly is used in a pressure cooking appliance 200, which includes an electric pressure cooker. It is understood that by mounting multiple components 3—typically including an exhaust valve (including an electronic exhaust valve 31 or a mechanical exhaust valve 32), a float assembly 33 (including a float valve or a float lock), and a detection assembly 34 (including a temperature sensor or a pressure sensor)—on the mounting portion 23, the mounting portion 23 becomes pressure-bearing, ensuring that the lid 2 can stably withstand pressure under high pressure. A seal is maintained between the mounting portion 23 and the lid 2 to prevent accidental release due to excessive pressure, thereby improving safety. Integrating multiple components 3 onto the mounting portion 23 not only simplifies the structure of the lid 2 but also ensures that each component 3 operates reliably during cooking. Furthermore, since the components 3 are concentrated on the mounting part, it is not only convenient to directly install multiple components on the mounting part 23, but also convenient to assemble the mounting part 23, which integrates multiple components 3, with the cover plate 2, so that the mounting part 23 can be better connected and sealed with the cover plate 2, thereby achieving better pressure bearing.

[0065] Therefore, in one embodiment of this utility model, the plurality of gas components include at least one of an electronic exhaust valve 31, a mechanical exhaust valve 32, a float assembly 33, and a detection assembly 34. The inner cavity of the electronic exhaust valve 31 communicates with the mounting cavity 24; the inner cavity of the mechanical exhaust valve 32 communicates with the mounting cavity 24; the float assembly 33 is mounted on the mounting portion 23 for contacting the steam in the mounting cavity 24; the detection assembly 34 is mounted on the mounting portion 23 for contacting the steam in the mounting cavity 24 to detect the temperature or pressure of the steam.

[0066] Understandably, by fastening or covering the pot body 6 with the lid, when the water inside the pot body 6 is heated to boiling, it transforms into steam. As steam is continuously generated, the pressure inside the pot body 6 gradually increases. When the steam wants to overflow due to the increased pressure, it begins to exert pressure on the outside. Since the cover plate 2 is located on the side facing the pot body 6, the energy of the steam is converted into pressure on the cover plate 2. First, the steam enters the mounting cavity 24 through the steam passage 22 located in the mounting area 21 on the cover plate 2, and the steam passage 22 serves as the inlet of the mounting cavity 24. Within the mounting cavity 24, the steam is distributed and guided to multiple components 3. When multiple components 3 are in communication with the steam, the steam overflows into the external environment through the components 3, thereby maintaining the steam pressure inside the pot body 6 at a certain value and avoiding safety hazards caused by excessive pressure. When multiple components 3 can come into contact with steam, the physical parameters of the steam can be monitored. By detecting these parameters, the physical state of the steam can be understood in real time, thus improving the safety of use.

[0067] It is understood that the mechanical exhaust valve 32 can be any of the following: float-type automatic exhaust valve, lever-type automatic exhaust valve, pulse-type automatic exhaust valve, spring-type automatic exhaust valve, angle seat-type automatic exhaust valve, and turbine-type automatic exhaust valve. Through a pre-set pressure preset value, the pressure inside the mechanical exhaust valve 32 is kept consistent with the pressure in the mounting chamber 24. When the pressure inside the mechanical exhaust valve 32 is less than the preset pressure value, the mechanical exhaust valve 32 is disconnected, preventing steam in the mounting chamber 24 from escaping into the external environment. When the pressure inside the mechanical exhaust valve 32 is greater than or equal to the preset pressure value, the mechanical exhaust valve 32 is connected, allowing steam in the mounting chamber 24 to escape into the external environment.

[0068] It is worth mentioning that the mechanical exhaust valve 32 can also be configured as a fusible disc safety valve. By setting the melting point temperature of the fusible disc, if other exhaust devices fail to respond in time or malfunction, the fusible disc will act as a last line of defense. At this time, the high temperature inside the pot body 6 will melt the fusible disc, thereby opening the exhaust channel and releasing the overpressurized gas or liquid inside to avoid safety hazards.

[0069] It should be noted that the number of mechanical exhaust valves 32 can be one or more, and the multiple mechanical exhaust valves 32 can be set differently or the same, without any particular limitation. Furthermore, the mechanical exhaust valves 32 can be installed on the side of the mounting part 23 facing the cover plate 2 or on the side of the mounting part 23 facing the pot lid body 1. In this embodiment, the mechanical exhaust valves 32 are installed on the side of the mounting part 23 facing the pot lid body 1 to avoid excessive contact between the external features of the mechanical exhaust valves 32 and steam and food residue that may overflow from the pot body 6, thus reducing their service life.

[0070] Understandably, the electronic steam release valve 31 is controlled by a built-in microprocessor or electronic control unit. The user can set the desired cooking pressure through the control panel of the cooking appliance 200, and the electronic steam release valve 31 will automatically adjust the steam release according to this setting.

[0071] Alternatively, the electronic exhaust valve 31 can be installed on the side of the mounting part 23 facing the cover plate 2 or on the side of the mounting part 23 facing the pot lid body 1. In this embodiment, the electronic exhaust valve 31 is installed on the side of the mounting part 23 facing the pot lid body 1 to avoid excessive contact between the external features of the electronic exhaust valve 31 and steam and food residue that may overflow from the pot body 6, thus reducing its service life. At the same time, it also avoids damage to the internal circuitry of the electronic exhaust valve 31 caused by high-temperature and high-pressure steam.

[0072] Understandably, the float assembly 33 can be a float valve. When the pot body 6 is in operation, it generates steam pressure. As the pressure increases, the float in the float valve rises. When the float reaches a certain position, it locks the push rod connecting plate, thus restricting the opening and closing of the pot lid. The pot lid can only be opened when the pressure inside the pot body 6 drops to a safe level. This prevents the pot lid from accidentally opening under high pressure inside the pot, reducing safety hazards.

[0073] It is understood that in this embodiment, the detection component 34 includes a temperature sensor or a pressure sensor. The temperature sensor (a thermistor sensor—the resistance of a thermistor changes with temperature; by measuring the change in resistance, the current temperature can be calculated; a thermocouple sensor—a thermocouple consists of two metal wires of different materials; when the temperature of the contact point between the two metal wires changes, a thermoelectric potential difference is generated, which is proportional to the temperature. By measuring the thermoelectric potential difference, the temperature can be determined. The choice of temperature sensor includes, but is not limited to, the above two types) can monitor the temperature of the steam in real time and convert the temperature information into an electrical signal, which is then transmitted to the control system. The control system adjusts the power of the heating element based on the received temperature signal to ensure that the temperature inside the pot remains within the set range. This helps to achieve precise cooking control, ensuring the taste and nutrition of the food. Meanwhile, the temperature sensor can also be electrically connected to the electronic exhaust valve 31. When the temperature sensor detects that the temperature of the steam in the mounting cavity 24 is greater than or equal to the preset safe temperature, the electronic exhaust valve 31 is connected so that the steam in the mounting cavity 24 can overflow into the external environment through the inner cavity of the electronic exhaust valve 31. When the temperature sensor detects that the temperature of the steam in the mounting cavity 24 is less than the preset safe temperature, the electronic exhaust valve 31 is disconnected so that the steam in the mounting cavity 24 cannot overflow into the external environment through the inner cavity of the electronic exhaust valve 31.

[0074] Pressure sensors (strain gauge pressure sensors – which measure pressure by utilizing the characteristic that the resistance of a strain gauge changes with pressure. The strain gauge is attached to an elastic element; when pressure is applied to the elastic element, the strain gauge deforms, causing a change in resistance. By measuring the change in resistance, the current pressure can be calculated; piezoelectric pressure sensors – when a dielectric is subjected to external force, it undergoes polarization, thereby generating a charge on its surface. By measuring the amount of these charges, the pressure magnitude can be determined. The choice of pressure sensor includes, but is not limited to, the above two types) are used to monitor the temperature of steam and convert pressure information into an electrical signal to transmit to the control system. This ensures that the pressure inside the pot 6 remains within a safe range. This helps prevent dangerous situations caused by excessive pressure.

[0075] Meanwhile, the pressure sensor can also be electrically connected to the electronic exhaust valve 31. When the pressure sensor detects that the pressure of the steam in the mounting cavity 24 is greater than or equal to the preset safety pressure, the electronic exhaust valve 31 is connected so that the steam in the mounting cavity 24 can overflow into the external environment through the inner cavity of the electronic exhaust valve 31; when the pressure sensor detects that the pressure of the steam in the mounting cavity 24 is less than the preset safety pressure, the electronic exhaust valve 31 is disconnected so that the steam in the mounting cavity 24 cannot overflow into the external environment through the inner cavity of the electronic exhaust valve 31.

[0076] It should be noted that the steam pressure and steam intensity mentioned in this application are interchangeable, which will not be elaborated further here.

[0077] In one embodiment, the cover plate 2 has a groove 25 formed on the side facing the pot lid body 1, and the groove 25 forms the mounting area 21; the mounting part 23 and the groove 25 together enclose the mounting cavity 24.

[0078] Understandably, the groove 25 increases the volume of the mounting cavity 24 formed between it and the mounting part 23, thereby controlling the volume of steam entering the mounting cavity 24 through the steam passage 22. This not only provides a buffering effect, allowing steam to flow simultaneously to multiple components 3, but also reduces interference between them, thus improving the reliability of the lid. The shape, size, and position of the groove 25 can be designed according to the actual operational needs of the multiple components 3, and are not specifically limited here.

[0079] In one embodiment, the mounting area 21 of the cover plate 2 is recessed in the direction away from the pot lid body 1 to form the mounting cavity 24, and a local protrusion is formed on the side of the cover plate 2 away from the pot lid body 1.

[0080] This design, without altering the structure of the pot lid body 1, allows for a further increase in the volume of the mounting cavity 24, enhancing the buffering effect on steam and reducing the steam flow rate so that it can be dispersed to the working areas of multiple components 3. At the same time, the raised structure can prevent food residues ejected from the pot body 6 from directly contacting the components 3, thus avoiding any impact on the working areas of the components 3.

[0081] It is worth mentioning that this raised design allows for flexible placement of the steam passage 22, enabling better control of steam flow by adjusting its position according to different ventilation requirements. Simultaneously, the partially raised design facilitates easier removal of residue accumulated on the cover plate 2 during cleaning. This design reduces dead zones, resulting in more thorough cleaning, while also preventing residue from clogging the steam passage 22, ensuring smooth steam flow.

[0082] In one embodiment, the steam passage holes 22 on the mounting area 21 are provided in a plurality of configurations.

[0083] With this configuration, multiple steam vents 22 can increase the flow of steam, ensuring that the steam inside the cooking appliance 200 can be distributed more evenly. Even if one or more steam vents 22 are blocked, the other steam vents 22 can still ensure sufficient steam flow, thereby improving the reliability of the lid.

[0084] It should be noted that the shape of the steam passage 22 can be set to be the same or different, which will not be elaborated further here.

[0085] It is worth mentioning that when the overall flow rate of the steam passage 22 is determined, the more steam passages 22 are set, the lower the probability of food residue in the pot body 6 being pumped into the installation cavity 24, the lower the risk of a sudden increase in internal pressure due to blockage of a single steam passage 22, and the easier it is to clean.

[0086] In one embodiment, the mounting portion 23 is integrally formed on the pot lid body 1.

[0087] This design, where the mounting section 23 and the pot lid body 1 are integrally formed, eliminates the need for additional assembly steps, simplifying the assembly process and reducing production costs. The integral design also provides better sealing, as the absence of additional seams or connections could lead to steam leakage. This better protects the components 3 mounted on the mounting section 23 from steam, helping to ensure the normal operation and lifespan of the components 3.

[0088] In one embodiment, the mounting part 23 is separately disposed from the pot lid body 1.

[0089] Understandably, multiple components 3 are integrated onto the mounting section 23, and the pot lid body 1 is installed after the mounting section 23 is aligned with the mounting area 21 of the cover plate 2. This integrated modular design simplifies the layout and connection process of the components 3. When it is necessary to replace or upgrade the components 3, only the mounting section 23 needs to be replaced, without disassembling the entire pot lid body 1, thus greatly reducing maintenance costs and time.

[0090] In one embodiment, a sealing ring 4 is provided between the mounting part 23 and the mounting area 21.

[0091] Understandably, the sealing ring 4 effectively fills the tiny gap at the connection between the mounting part 23 and the mounting area 21, forming a tight sealing barrier. This prevents steam in the mounting cavity 24 from entering the second side of the lid body 1 through this tiny gap, affecting the components or parts 3 located thereon, and causing the lid to malfunction and become inoperable.

[0092] In one embodiment, the cover plate 2 has a groove 25 formed on the side facing the pot lid body 1, the groove 25 forms the mounting area 21, and the mounting part 23 and the groove 25 surround to form the mounting cavity 24; one end of the sealing ring 4 is fixedly connected to the mounting part 23, and the other end extends into the bottom of the groove 25 and seals against the groove 25.

[0093] It is understood that the fixed connection can be achieved through adhesive bonding, snap-fitting, or mechanical fixing, but is not limited to these methods. The specific method depends on the material and shape of the sealing ring 4 and the design of the mounting part 23. Specifically, in this application, the sealing ring 4 is securely fixed to the mounting part 23 by screws using a sealing ring. This fixed connection not only prevents the sealing ring 4 from shifting or falling off during installation, but also ensures that the sealing performance of the sealing ring 4 will not decrease during long-term use. The portion of the sealing ring 4 that extends into the bottom of the groove 25 and seals against the groove 25 allows steam in the mounting cavity 24 to exert pressure on this portion of the sealing ring 4, pressing it tightly against the groove wall of the cover plate 2 groove 25. This not only enhances the sealing performance of the sealing ring 4, but also improves its resistance to steam leakage. Even under conditions of steam pressure fluctuations or vibration of the lid or pot body 6, the sealing ring 4 can maintain a stable sealing state, preventing steam or other media from overflowing from the gap between the mounting part 23 and the cover plate 2.

[0094] In one embodiment, the pot lid body 1 is provided with a through hole, and the plurality of components 3 are provided corresponding to the through hole.

[0095] This configuration allows the components 3 to pass directly through the pot lid body 1 and be exposed on the pot lid body 1, enabling connection with the power system arranged on the pot lid body 1. This provides power or signal control to the electrical control components 3 installed on the mounting section 23. At the same time, the working status of multiple components 3 on the mounting section 23 can be directly observed. Without disassembling and separating the pot lid body 1 from the cover plate 2, the components 3 can be directly disassembled and replaced, improving the convenience of maintenance and repair.

[0096] Please see Figure 2 and Figure 6 In one embodiment, the mounting part 23 is sandwiched between the pot lid body 1 and the lid plate 2.

[0097] Understandably, by connecting the pot lid body 1 and the lid plate 2, the mounting part 23 is placed between them, providing stable support for the mounting part 23 and effectively limiting its movement and deformation. This clamping method not only improves the installation strength of the mounting part 23 but also reduces the risk of loosening or damage caused by the continuous irregular vibration of the pot body 6 due to boiling water during use.

[0098] Please see Figure 2 and Figure 6 In one embodiment, a concave-convex fitting structure 5 is provided between the cover plate 2 and the mounting part 23 to limit the mounting part 23; a concave-convex fitting structure 5 is provided between the pot lid body 1 and the mounting part 23 to limit the mounting part 23.

[0099] It is understandable that the concave-convex mating structure 5 can increase the contact area between the mounting part 23 and the cover plate 2 and the pot lid body 1, improve the sealing and stability of the connection, and at the same time, it can also position the mounting part 23 between the cover plate 2 and the pot lid body 1, improving the accuracy of the connection.

[0100] Specifically, the convex-concave mating structure 5 includes a protrusion and a concave portion. When the protrusion is inserted into the concave portion, the two achieve a tight connection through precise matching of shape and size. When the mounting part 23 is provided with a protrusion, the corresponding part of the pot lid body 1 or the lid plate 2 is provided with a concave portion; when the mounting part 23 is provided with a concave portion, the corresponding part of the pot lid body 1 or the lid plate 2 is provided with a protrusion. The number of convex-concave mating structures 5 can be one or more, which will not be elaborated further here. More specifically, in this embodiment, the convex-concave mating structure 5 is an annular convex-concave fit, and the annular protrusion can be inserted into the annular groove 25 to form a complete circumferential seal.

[0101] Please see Figure 1 and Figure 2 This utility model also proposes a cooking utensil 200, which includes a pot body 6 and a lid assembly 100. The specific structure of the lid assembly 100 is as described in the above embodiments. Since this cooking utensil 200 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The pot body 6 has an opening, and the lid assembly 100 is disposed facing the opening corresponding to the pot body 6.
