Description

Technical Field

[0001] The present invention relates to the technical field of household appliances, and in particular to a cooking utensil. Background Art

[0002] Currently, most existing pressure-bake cookers utilize a single pot body with two lids to achieve both pressure cooking and baking. However, one of the two lids is always unused, requiring a dedicated location to store the unused lid. Furthermore, when the pressure-bake cooker is not in use, one of the lids also requires a dedicated location, taking up a lot of space and making it difficult to store the pressure-bake cooker.

[0003] In other words, the cooking utensils in the prior art have the problem of being difficult to store. Summary of the Invention

[0004] The main purpose of the present invention is to provide a cooking utensil to solve the problem that cooking utensil in the prior art is difficult to store.

[0005] In order to achieve the above-mentioned purpose, according to one aspect of the present invention, a cooking utensil is provided, comprising a pot cover and a pot body, the pot body having a heating structure, the pot cover being openably and closably arranged on the pot body, the pot cover comprising: a lid assembly; a baking assembly, the baking assembly being arranged in the lid assembly; and an inner cover, the inner cover being detachably arranged below the baking assembly.

[0006] By arranging both a baking assembly and an inner lid on the pot lid, the cooking appliance can be used for both baking and high-pressure cooking, increasing the functional versatility of the cooking appliance. Since the inner lid is detachably positioned below the baking assembly, when the cooking appliance is required for baking, the inner lid is removed, exposing the baking assembly for baking the food inside the pot. When the cooking appliance is required for high-pressure cooking, the inner lid is installed below the baking assembly, sealing the high-pressure gas inside the pot for high-pressure cooking. Furthermore, the inner lid is detachably positioned below the baking assembly, making it easier to store the inner lid. When the cooking appliance is no longer in use, the inner lid is installed below the baking assembly and the pot lid is placed back on the pot.

[0007] Furthermore, the baking assembly includes a detachable heating tube assembly. By installing the detachable heating tube assembly in the baking assembly, the heating tube assembly and the cover assembly are detachably connected, making it easier to clean the heating tube assembly. This reduces the buildup of dirt on the heating tube assembly after long-term use, increases the heat transfer efficiency of the heating tube assembly, and enables faster cooking. The surface where the heating tube is mounted is easily cleaned, ensuring a cleaner interior of the baking assembly. Furthermore, this arrangement allows for quick replacement of the heating tube assembly, ensuring stable operation of the baking assembly.

[0008] Furthermore, the heating tube assembly includes: a heating element; two lead-out structures, each disposed at one end of the heating element, with at least a portion of each lead-out structure extending into the heating element's tube body and electrically connected to the heating wire of the heating element; and a fixing base, to which the two lead-out structures are fixed at intervals. By providing the lead-out structures and fixing base in the baking assembly, the heating element and the cover assembly are removably connected, facilitating cleaning of the heating element and increasing the convenience of cleaning the heating element. This reduces dirt accumulated on the heating element after long-term use, increases the heat transfer efficiency of the heating element, and enables faster cooking in the cooking appliance. Furthermore, this arrangement allows for quick replacement of the heating element, ensuring stable operation of the baking assembly. If the heating element is damaged, only the heating element needs to be replaced, without having to replace the entire baking assembly, reducing the maintenance cost of the cooking appliance. This ensures that the ends of the heating element are fixed and powered, improving the reliability of power supply to the heating element.

[0009] Furthermore, the length of the lead-out structure extending into the tube body is not less than 8 mm. This can effectively reduce the problem of poor contact between the lead-out structure and the heating wire, and increase the stability of the electrical connection between the lead-out structure and the heating wire.

[0010] Furthermore, the heating element is a glass heating tube. The glass heating tube has the characteristics of fast heating and high power, so that the cooking appliance can reach the required temperature in a short time, the cooking appliance can heat up quickly, reducing cooking time and increasing cooking convenience.

[0011] Furthermore, the two lead-out structures are inserted into the fixing seat, which fixes the gap between the two lead-out structures to fit with the third plug-in terminal, thereby stably supplying power to the heating element.

[0012] Furthermore, the fixing base includes a base body, one end of the lead structure inserted into the base body being provided with a threaded section; and two conductive pins, each threadedly connected to the two lead structures in a one-to-one correspondence, with one end of the conductive pin extending outward from the base body. The threaded connection between the lead structure and the conductive pins can increase the tightness of the connection between the lead structure and the conductive pins and reduce the possibility of separation between the lead structure and the conductive pins.

[0013] Furthermore, the end of the heating element is flat, which makes it difficult for the end of the heating element to shake, thereby preventing the end of the heating element from being separated from the fixing seat.

[0014] Furthermore, the lead-out structure is a lead-out rod, which is easy to connect with the heating wire, reducing the possibility of breakage between the heating wire and the lead-out rod.

[0015] Furthermore, the tube body, heating wire and lead-out structure are fixed by hot pressing, which makes the connection between the tube body, heating wire and lead-out structure tighter and avoids the possibility of separation between the tube body, heating wire and lead-out structure.

[0016] Furthermore, the cover assembly has a third plug-in terminal, the baking assembly also includes a fourth plug-in terminal that cooperates with the third plug-in terminal, the conductive end of the fixing seat is electrically connected to the fourth plug-in terminal; and / or the fixing seat is a ceramic fixing seat; and / or the assembly gap between the fixing seat and the lead-out structure is filled with high-temperature glue. The third plug-in terminal is connected to the power supply system in the cover assembly to enable the cooking appliance to supply power to the third plug-in terminal, and then to supply power to the fourth plug-in terminal, so that the fourth plug-in terminal supplies power to the heating element, causing the heating element to heat and operate. The use of ceramic material can reduce the conductivity of the fixing seat, reduce safety hazards, and increase the safety of the cooking appliance. This prevents high-temperature gas in the cooking appliance from entering the cover assembly through the assembly gap between the fixing seat and the lead-out structure during operation of the cooking appliance, thereby reducing damage to internal components of the cover assembly caused by high temperature and increasing the stability of the cooking appliance.

DETAILED DESCRIPTION

[0085] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0086] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0087] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity direction; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above directional words are not used to limit the present invention.

[0088] In order to solve the problem that cooking utensils in the prior art are difficult to store, the present invention provides a cooking utensil.

[0089] like Figures 1 to 5 As shown, the cooking utensil includes a pot cover 10 and a pot body. The pot cover 10 can be opened and closed on the pot body. The pot body has a heating structure. The pot cover 10 includes a cover assembly 30, a baking assembly 40 and an inner cover 50. The baking assembly 40 is arranged in the cover assembly 30, and the inner cover 50 is detachably arranged below the baking assembly 40.

[0090] By simultaneously providing the baking assembly 40 and the inner cover 50 on the pot lid 10, the cooking appliance can be used for both baking and pressure cooking, increasing the functional versatility of the cooking appliance. Since the inner cover 50 is detachably positioned below the baking assembly 40, when the cooking appliance is required for baking, the inner cover 50 is removed, exposing the baking assembly 40 for baking the food inside the pot. When the cooking appliance is required for pressure cooking, the inner cover 50 is installed below the baking assembly 40, sealing the high-pressure gas inside the pot for pressure cooking. Furthermore, the inner cover 50 is detachably positioned below the baking assembly 40, making it easier to store the inner cover 50. When the cooking appliance is not in use, the inner cover 50 is installed below the baking assembly 40 and the pot lid 10 is placed on the pot body 20.

[0091] It should be noted that in the present application, baking can be achieved without arranging a fan in the cooking utensil, which greatly reduces the use of structural parts and saves energy. In addition, the cleaning of the fan can be reduced, making it easier to clean the cooking utensil.

[0092] Example 1

[0093] Specifically, the baking assembly 40 includes a detachable heating element assembly. By providing the detachable heating element assembly in the baking assembly 40, the heating element assembly and the cover assembly 30 are detachably connected, making it easier to clean the heating element assembly. This reduces the buildup of dirt on the heating element assembly after long-term use, increases its heat transfer efficiency, and allows for faster cooking. The surface where the heating element is mounted is easily cleaned, ensuring a cleaner interior of the baking assembly. Furthermore, this arrangement allows for quick replacement of the heating element assembly, ensuring stable operation of the baking assembly 40.

[0094] like Figure 4 As shown, the heating tube assembly includes a heating element 41, two lead-out structures 46, and a fixing base 47. The two lead-out structures 46 are respectively disposed at both ends of the heating element 41. At least a portion of each lead-out structure 46 extends into the tube body 411 of the heating element 41 and is electrically connected to the heating wire 412 of the heating element 41. The two lead-out structures 46 are fixed to the fixing base 47 at intervals. By providing the lead-out structures 46 and fixing base 47 in the baking assembly 40, the heating element 41 and the cover assembly 30 are detachably connected, which facilitates cleaning of the heating element 41 and increases the convenience of cleaning the heating element 41. This reduces dirt accumulated on the heating element 41 after long-term use, increases the heat transfer efficiency of the heating element 41, and enables the cooking device to cook quickly. In addition, this arrangement allows for quick replacement of the heating element 41, ensuring stable operation of the baking assembly 40. If the heating element 41 is damaged, only the heating element 41 can be replaced without replacing the entire baking assembly 40, reducing the maintenance cost of the cooking device. The fixing and power supply of the end of the heating element 41 are achieved, and the reliability of the power supply to the heating element is improved.

[0095] It should be noted that, in this application, the lead-out structure 46 serves as a connecting bridge for the heating wire 412, allowing the cover assembly 30 to supply power to the heating wire 412. Because the heating wire 412 is relatively fragile and easily damaged by collisions with other structural components, the lead-out structure 46 also provides protection for the heating wire 412, preventing breakage and increasing the operational stability of the heating wire 412. The fixing base 47 provides positioning for the lead-out structures 46, ensuring a fixed spacing between the two lead-out structures 46, thereby ensuring accurate electrical connection between the lead-out structures 46 and the cover assembly 30 or the baking assembly 40.

[0096] Specifically, the lead structure 46 extends into the tube body 411 for a length of no less than 8 mm. This effectively reduces contact problems between the lead structure 46 and the heating wire 412, increasing the stability of electrical conduction between the lead structure 46 and the heating wire 412. Furthermore, the lead structure 46 protects the heating wire 412, reducing the likelihood of breakage.

[0097] In the present application, the heating element 41 is a glass heating tube. The glass heating tube has the characteristics of fast heating and high power, which enables the cooking appliance to reach the required temperature in a short time. The cooking appliance can heat up quickly, reducing cooking time and making cooking more convenient.

[0098] In a specific embodiment (not shown), the cover assembly 30 has a third plug terminal 38, and the baking assembly 40 also includes a fourth plug terminal (not shown) that mates with the third plug terminal 38. The conductive end of the fixing base 47 is electrically connected to the fourth plug terminal. The third plug terminal 38 is connected to the power supply system in the cover assembly 30, so that the cooking appliance can supply power to the third plug terminal 38, which in turn supplies power to the fourth plug terminal, which in turn supplies power to the heating element 41, causing the heating element 41 to heat. In this embodiment, two lead structures 46 are plugged into the fourth plug terminal, establishing an electrical connection between the two lead structures 46 and the fourth plug terminal.

[0099] exist Figure 1 In the illustrated embodiment, the cooking appliance comprises only the third plug-in terminal 38 on the cover assembly 30, and two lead structures 46 are plugged into the third plug-in terminal 38 to provide power to the heating element 41. Alternatively, the combination of the fixing base 47 and the two lead structures 46 constitutes a plug-in terminal that mates with the third plug-in terminal 38. The cover assembly 30 also comprises a fixing structure 32 for securing the third plug-in terminal 38.

[0100] It should be noted that the third plug-in terminal 38 is a female plug, while the plug-in terminal formed by the combination of the fixing base 47 and the two lead structures 46 is a male plug. This combination allows the heating element 41 to be detached from the cover assembly 30, facilitating cleaning and replacement of the heating element 41 and increasing the stability of the cooking appliance. Furthermore, the electrically coupled power supply offers the advantages of rapid power supply and ease of maintenance.

[0101] Specifically, the fixing base 47 is a ceramic fixing base. Fixing base 47 not only secures the two lead structures 46 but is also frequently used for plugging and unplugging. Using ceramic reduces the conductivity of fixing base 47, minimizing safety hazards and increasing the safety of the cooking appliance. Furthermore, ceramic is resistant to high temperatures, minimizing the impact of the heating element 41 on the ceramic fixing base, reducing damage to fixing base 47 and increasing its stability and safety.

[0102] In this application, the assembly gap between the fixing base 47 and the outlet structure 46 is filled with high-temperature glue. This prevents high-temperature gases from entering the cover assembly 30 through the assembly gap between the fixing base 47 and the outlet structure 46 during operation of the cooking appliance, thereby reducing damage to the internal components of the cover assembly 30 caused by high temperature and increasing the stability of the cooking appliance.

[0103] like Figure 1 and Figure 4 As shown, the two lead-out structures 46 are inserted into the fixing seat 47. The fixing seat 47 fixes the gap between the two lead-out structures 46 to adapt to the third plug-in terminal 38, thereby stably supplying power to the heating element 41. In addition, the fixing seat 47 can also prevent the two lead-out structures 46 from shaking, thereby reducing the collision between the lead-out structures 46 and other structural components, increasing the safety of the lead-out structures 46, and ensuring stable operation of the lead-out structures 46.

[0104] like Figure 3 As shown, the fixing base 47 includes a base body 471 and conductive pins 472. The end of the lead structure 46 inserted into the base body 471 is provided with a threaded section. There are two conductive pins 472, each threadedly connected to the two lead structures 46 in a one-to-one correspondence. One end of the conductive pins 472 extends outward from the base body 471. The threaded connection between the lead structure 46 and the conductive pins 472 enhances the tightness of the connection and reduces the possibility of separation between the lead structure 46 and the conductive pins 472. The provision of the conductive pins 472 also reduces the length of the lead structure 46, reducing the risk of collision when the lead structure 46 is inserted into the base body 471. This arrangement facilitates the installation of the heating element 41.

[0105] like Figure 3 As shown, the end of the heating element 41 is flat. The flat structure is not easy to shake, so that the end of the heating element 41 is not easy to separate from the fixing base 47, which increases the stability of the connection between the heating element 41 and the fixing base, so that the heating element 41 can work stably.

[0106] Specifically, the lead-out structure 46 is a lead-out rod, which is easy to connect with the heating wire 412, thereby reducing the possibility of breakage between the heating wire 412 and the lead-out rod.

[0107] Specifically, the tube body 411, heating wire 412, and lead structure 46 are fixed by hot pressing. The tube body 411, heating wire 412, and lead structure 46 are fixed by hot pressing at the end of the tube body 411 to form a flat end. The hot pressing and forming of the tube body 411, heating wire 412, and lead structure 46 provides a tighter connection, preventing the possibility of separation between the tube body 411, heating wire 412, and lead structure 46.

[0108] One end of the lead-out structure 46 is flattened and connected to the heating wire 412 by welding, and then the end of the tube body 411 is fixed by heat and pressure. After being fixed, the seat body 471 is put on to locate the center distance between the two lead-out structures 46. After that, the two lead-out structures 46 are fully fixed by using the internal thread and external hexagon provided on the conductive pin 472, and then high-temperature glue is filled into the assembly gap between the lead-out structure 46 and the fixing seat 47. This arrangement ensures the center distance while also ensuring the structural force of the two lead-out structures 46.

[0109] Example 2

[0110] like Figures 6 to 11 As shown, the cooking utensil includes a pot cover 10 and a pot body. The pot cover 10 can be opened and closed on the pot body. The pot cover 10 includes a cover assembly 30, a baking assembly 40, an inner cover 50, a temperature sensing element 60 and a heat insulation protection assembly 90. The baking assembly 40 is arranged in the cover assembly 30 and includes a reflective cover 43 and a heating element 41. The temperature sensing element 60 extends downward from the cover assembly 30 through the reflective cover 43. The heat insulation protection assembly 90 is located between the temperature sensing element 60 and the heating element 41.

[0111] Since the temperature within the pot needs to be monitored during baking, the thermal insulation assembly 90 prevents direct heat radiation from reaching the temperature sensor 60, reducing the frequency of temperature sensor 60's operation. The temperature sensor 60 extends downward from the lid assembly 30, passing through the baking assembly 40 and inner lid 50 to reach the pot. The operation of the baking assembly 40 can easily affect the temperature sensor 60. The thermal insulation assembly 90 reduces the amount of heat radiated from the heating element 41 to the temperature sensor 60, preventing the sensitivity of the temperature sensor 60 from being reduced due to frequent temperature sensing and control. This improves temperature sensing accuracy and allows the cooking appliance to heat up quickly.

[0112] like Figure 6 and Figure 7 As shown, the heat-insulating protection assembly 90 is mounted on the temperature-sensing element 60 and is located below the reflective cover 43. The heat-insulating protection assembly 90 is mounted on the temperature-sensing element 60 to provide all-round protection for the temperature-sensing element 60, thereby reducing the amount of heat transferred to the temperature-sensing element 60 and increasing the accuracy of the temperature sensing and temperature control of the temperature-sensing element 60.

[0113] like Figure 6 and Figure 7As shown, the heat-insulating protective assembly 90 includes a temperature-sensitive reflective sleeve 91, and the heating element 41 is located above the lower end surface of the temperature-sensitive reflective sleeve 91. At least a portion of the temperature-sensitive reflective sleeve 91 is fitted against the reflective cover 43 to reduce heat from entering the temperature-sensitive element 60 through the gap between the temperature-sensitive reflective sleeve 91 and the reflective cover 43, thereby reducing heat from directly radiating to the temperature-sensitive element 60 and protecting the temperature-sensitive element 60. This reduces the need for frequent temperature sensing and control by the temperature-sensitive element 60 during baking operations, allowing the temperature-sensitive element 60 to be used only when needed, thereby increasing the accuracy of the temperature sensing by the temperature-sensitive element 60.

[0114] like Figure 8 As shown, the baking assembly 40 also includes a protective net 42, and the heating element 41 is fixed to the reflector 43 through the protective net 42. Since the contact area between the protective net 42 and the heating element 41 is large, the heating element 41 is supported and the heating element 41 works stably.

[0115] like Figure 8 As shown, the thermal insulation protection assembly 90 also includes a thermal insulation member 92 disposed between the temperature-sensitive reflective sleeve 91 and the temperature-sensitive element 60. The temperature-sensitive reflective sleeve 91 reflects heat away from the temperature-sensitive element 60, but some heat will still remain on the temperature-sensitive reflective sleeve 91. To effectively isolate this heat, the thermal insulation member 92 is added. The thermal insulation member 92 acts as a secondary protection for the temperature-sensitive element 60, minimizing the amount of heat transferred to the temperature-sensitive element 60 and ensuring that the thermal insulation protection assembly 90 provides excellent protection for the temperature-sensitive element 60.

[0116] like Figure 10 and Figure 11 As shown, both ends of the heat insulating member 92 have a constricted section 921. The setting of the constricted section 921 facilitates the placement of the heat insulating member 92 between the temperature sensing element 60 and the temperature sensing reflective sleeve 91, so that the temperature sensing reflective sleeve 91 and the temperature sensing element 60 have a smooth transition and are easy to clean.

[0117] like Figure 10 As shown, the heat insulating member 92 is a heat insulating ring. The heat insulating ring is sleeved on the temperature sensing element 60 to form an all-round protection for the temperature sensing element 60 and reduce the impact of the heat of the baking assembly 40 on the temperature sensing element 60.

[0118] Specifically, the thermal insulation ring and the temperature-sensitive reflective sleeve 91 are seamlessly integrated. This arrangement creates a small gap or interference fit between the thermal insulation ring and the temperature-sensitive reflective sleeve 91, making it easier to place the thermal insulation ring between the temperature-sensitive reflective sleeve 91 and the temperature-sensitive element 60. It also facilitates operations such as replacing or removing the thermal insulation ring for cleaning. Furthermore, the seamless fit between the thermal insulation ring and the temperature-sensitive reflective sleeve 91 prevents relative movement, allowing the thermal insulation ring to stably insulate the temperature-sensitive element 60 and block contaminants.

[0119] like Figure 7 As shown, the heating element 41 surrounds the outer periphery of the temperature sensing element 60. This arrangement makes the temperature detected by the temperature sensing element 60 more accurate, thereby increasing the accuracy of temperature control by the temperature sensing element 60.

[0120] Optionally, the thermal insulation ring is a ceramic thermal insulation ring. Ceramic thermal insulation rings have excellent thermal insulation properties and are resistant to high temperatures, making them less susceptible to high temperatures. This increases the thermal insulation stability of the thermal insulation ring and reduces component replacement costs. Of course, thermal insulation rings made of other materials are also acceptable, but other materials are more susceptible to high temperatures.

[0121] like Figure 8 As shown, the inner cover 50 has a through-hole 51 through which the temperature sensing element 60 extends. The thermal insulation protection assembly 90 also includes a sealing ring 93, which is located within the temperature sensing reflective sleeve 91 and seals the through-hole 51. After the temperature sensing element 60 extends through the through-hole 51, it is assembled with the positioning nut 80 to limit the shaking of the inner cover 50 and improve the tightness of the connection between the inner cover 50 and the baking assembly 40. The sealing ring 93 is used to seal the gap between the temperature sensing element 60 and the pot lid 10 at the through-hole 51, reducing the high-pressure gas in the pot from flowing through the hole 51 into the baking assembly 40 and the lid assembly 30, thereby reducing the damage caused by the moist, high-temperature gas to the baking assembly 40 and the lid assembly 30, thereby improving the stability of the cooking appliance. At the same time, the sealing ring 93 can also prevent the leakage of high-pressure gas, reduce safety hazards, and increase the safety of the cooking appliance.

[0122] Optionally, the sealing ring 93 is made of silicone. Of course, it can also be made of other soft materials, such as rubber.

[0123] like Figure 8 As shown, the thermal insulation protection assembly 90 further includes a buffer member 94, which is disposed between the thermal insulation member 92 and the reflector 43. One end of the buffer member 94 abuts the reflector 43, and the other end abuts the thermal insulation member 92. This serves to compress the thermal insulation member 92 and the sealing ring 93 while not affecting the vertical movement of the temperature sensing element 60. Optionally, the buffer member 94 is a buffer spring.

[0124] like Figure 9 As shown, the end of the temperature-sensing reflective sleeve 91 near the pot body is shaped like a trumpet. This reflects heat from the heating element 41, preventing the temperature-sensing element 60 and the sealing ring 93 from being directly exposed to the high-temperature radiation from the heating element 41. The trumpet-shaped design maximizes its spatial position, protecting the sealing ring 93 while ensuring sufficient space for cleaning.

[0125] like Figure 6As shown, the pot lid 10 also includes an inner lid 50, which is removably mounted below the baking assembly 40. By arranging both the baking assembly 40 and the inner lid 50 on the pot lid 10, the cooking appliance can be used for both baking and pressure cooking, increasing the functional versatility of the cooking appliance. Since the inner lid 50 is removably mounted below the baking assembly 40, when the cooking appliance is to be used for baking, the inner lid 50 is removed, exposing the baking assembly 40 for baking the food inside the pot. When the cooking appliance is to be used for pressure cooking, the inner lid 50 is mounted below the baking assembly 40, sealing the high-pressure gas inside the pot and allowing pressure cooking of the food inside.

[0126] like Figure 11 As shown, the trumpet-shaped bottom is located below the heating element 41. This arrangement can prevent the high temperature emitted by the heating element 41 from being directly radiated to the sealing ring 93, thereby increasing the protection of the sealing ring 93 and increasing the service life of the sealing ring 93.

[0127] like Figure 9 As shown, the temperature-sensing reflective sleeve 91 includes a connecting flange 911, a receiving tube section 912, and a horn tube section 913 connected in sequence. The connecting flange 911 is tightly connected to the reflective cover 43. In the present application, the connecting flange 911 is fixed to the reflective cover 43 by screws. The buffer 94 is located in the receiving tube section 912. One end of the buffer 94 abuts against the reflective cover 43, and the other end abuts against the thermal insulation 92. It is used to compress the thermal insulation 92 and the sealing ring 93 while not affecting the upward and downward movement of the temperature-sensing element 60. At least a portion of the thermal insulation 92 is located in the receiving tube section 912, and another portion of the thermal insulation 92 is located in the horn tube section 913. The sealing ring 93 is sleeved on the temperature-sensing element 60 and located in the horn tube section 913. The thermal insulation 92 is located above the sealing ring 93.

[0128] Example 3

[0129] like Figures 12 to 16 As shown, the cooking utensil includes a pot cover 10 and a pot body, and the pot cover 10 can be opened and closed on the pot body, and the pot cover 10 includes a cover assembly 30, a baking assembly 40, an inner cover 50 and a temperature sensing element 60, wherein the baking assembly 40 is arranged in the cover assembly 30 and includes a first reflective cover 441, and the inner cover 50 is detachably arranged below the baking assembly 40, at least a portion of the temperature sensing element 60 extends downward from the cover assembly 30 through the first reflective cover 441, and the temperature sensing element 60 has a circumferential blocking ridge 61, which is located below the first reflective cover 441 or at least a portion of the circumferential blocking ridge 61 is located in the gap between the first reflective cover 441 and the temperature sensing element 60.

[0130] By simultaneously providing the baking assembly 40 and the inner cover 50 within the cooking appliance, the cooking appliance can be used for both baking and pressure cooking. Since the inner cover 50 is removably positioned below the baking assembly 40, when the cooking appliance is used for baking, the inner cover 50 is removed, allowing the baking assembly 40 to toast the food within the pot. When the cooking appliance is used for pressure cooking, the inner cover 50 is installed below the baking assembly 40, sealing the high-pressure gas within the pot for pressure cooking. At least a portion of the temperature sensing element 60 extends downward from the lid assembly 30 through the first reflector 441, bringing at least a portion of the temperature sensing element 60 closer to the pot, enabling more accurate temperature measurement. A circumferential blocking ridge 61 seals the gap between the first reflector 441 and the temperature sensing element 60, preventing high-temperature gas from entering the lid assembly 30 and potentially affecting its internal components. This also enhances the airtightness of the cooking appliance, reducing gas leaks during high-pressure cooking. This ensures gas is exhausted from a designated location, ensuring uniform exhaust flow, increasing safety, and reducing potential safety hazards. Since the baking assembly 40 generates high temperatures during baking, sealing the gap between the temperature sensing element 60 and the first reflector 441 prevents the baking assembly 40 from heating the cover assembly 30, preventing components within the cover assembly 30 from failing due to the high temperatures, thereby increasing the stability of the cooking appliance.

[0131] like Figure 12 As shown, the temperature sensing element 60 is in a floating connection with the cover assembly 30. When the circumferential blocking ridge 61 is located below the first reflector 441, the distance between the circumferential blocking ridge 61 and the first reflector 441 is no less than the travel range of the temperature sensing element 60. This arrangement ensures that the circumferential blocking ridge 61 does not affect the movement of the temperature sensing element 60, thereby ensuring stable operation of the temperature sensing element 60.

[0132] like Figure 12As shown, when at least a portion of the circumferential blocking ridge 61 is located in the gap between the first reflector 441 and the temperature sensing element 60, the lower surface of the circumferential blocking ridge 61 is flush with the lower surface of the first reflector 441. This arrangement ensures the flatness of the surface of the first reflector 441, ensuring that the first reflector 441 reflects heat into the pot, reducing heat transfer from the baking assembly 40 to the lid assembly 30, reducing heat loss, and increasing the baking efficiency of the baking assembly 40. Furthermore, it reduces the impact of high temperatures on the lid assembly 30 and enhances the stability of the cooking appliance. The flushness of the lower surface of the circumferential blocking ridge 61 with the lower surface of the first reflector 441 facilitates cleaning of the first reflector 441. Furthermore, the circumferential blocking ridge 61 fills the gap between the temperature sensing element 60 and the first reflector 441, making the lower surface of the first reflector 441 smooth and easy to clean.

[0133] like Figure 14 and Figure 15 As shown, the circumferential blocking ridge 61 includes a large-diameter section 611 and a small-diameter section 612 sequentially connected along the height of the temperature sensing element 60, giving the circumferential blocking ridge 61 a stepped shape, with the small-diameter section 612 located between the gaps. The small-diameter section 612 is positioned within the gaps, so that its lower surface is flush with the lower surface of the first reflector 441. The large-diameter section 611 is positioned outside the gaps, forming a secondary seal and enhancing the sealing effectiveness of the circumferential blocking ridge 61.

[0134] like Figure 12 As shown, the baking assembly 40 also includes a second reflector 442, which is disposed between the first reflector 441 and the cover assembly 30, with the large-diameter section 611 positioned above the second reflector 442. The provision of the second reflector 442 enhances the thermal insulation of the baking assembly 40 and reduces the impact of high temperatures on the cover assembly 30. It also reduces heat loss, increases baking efficiency, and facilitates faster cooking. The lower surface of the large-diameter section 611 and the upper surface of the second reflector 442 abut against each other, forming a seal with the first reflector 441 and preventing an unstable seal with the small-diameter section 612. The provision of the large-diameter section 611 and the small-diameter section 612 creates a secondary seal between the first reflector 441 and the temperature sensing element 60, providing a more effective sealing effect for the circumferential blocking ridge 61.

[0135] Optionally, the gap is no greater than 0.2 mm. This arrangement can prevent the heat from leaking from the gap when the seal is not tight, thereby reducing the impact of high temperature on the cover assembly 30.

[0136] like Figure 13As shown, the inner lid 50 has a through-hole 51 through which the temperature sensor 60 extends. The pot lid 10 also includes a sealing ring 70, which is positioned over the temperature sensor 60 and seals the through-hole 51. The inner lid 50 is detachably connected to the baking assembly 40 via the temperature sensor 60, enabling the cooking appliance to perform both high-pressure cooking and baking functions. After the temperature sensor 60 extends through the through-hole, it is assembled with a retaining nut 80 to limit movement of the inner lid 50 and enhance the tightness of the connection between the inner lid 50 and the baking assembly 40. The sealing ring 70 seals the gap between the temperature sensor 60 and the pot lid 10 at the through-hole 51, reducing the risk of high-pressure gas within the pot flowing through the through-hole 51 into the baking assembly 40 and the lid assembly 30, thereby increasing the stability of the cooking appliance. Furthermore, the sealing ring 70 prevents leakage of high-pressure gas, reducing safety hazards and enhancing the safety of the cooking appliance.

[0137] like Figure 14 and Figure 15 As shown, the temperature sensing element 60 further includes an assembly flange 62, which is located below the circumferential blocking flange 61. The sealing ring 70 is sleeved on the assembly flange 62. The mutual stop engagement between the assembly flange 62 and the sealing ring 70 reduces the possibility of the sealing ring 70 falling off the temperature sensing element 60, improves the sealing stability of the sealing ring 70, and reduces safety hazards.

[0138] like Figure 15 As shown, the upper and / or lower surfaces of the assembly flange 62 are provided with positioning grooves 621, and the sealing ring sleeve 70 is engaged with the positioning grooves 621. During assembly of the temperature sensing element 60 and the inner cover 50, the provision of the positioning grooves 621 prevents the sealing ring sleeve 70 from separating from the assembly flange 62, thereby enhancing the tightness of the connection between the sealing ring sleeve 70 and the assembly flange 62. The positioning grooves 621 also serve as a positioning function, ensuring that the sealing ring sleeve 70 is accurately installed on the assembly flange 62. In addition, since the inner cover 50 and the temperature sensing element 60 are frequently assembled and disassembled, placing the sealing ring sleeve 70 on the assembly flange 62 prevents it from being lost.

[0139] Specifically, the positioning groove 621 is an annular groove that matches the shape of the sealing ring 70 so that at least a portion of the sealing ring 70 is engaged with the interior of the positioning groove 621 , making it difficult for the sealing ring 70 to separate from the positioning groove 621 .

[0140] like Figure 13As shown, the temperature sensing element 60 includes a temperature sensing fixing seat 63 and a temperature sensing positioning rod 64. The temperature sensing positioning rod 64 is floatingly arranged on the cover assembly 30 via the temperature sensing fixing seat 63. The temperature sensing positioning rod 64 has a circumferential blocking flange 61. The temperature sensing fixing seat 63 provides a placement position for the temperature sensing positioning rod 64 and allows the temperature sensing positioning rod 64 to move relative to the cover assembly 30.

[0141] like Figure 14 and Figure 15 As shown, the temperature-sensing positioning rod 64 also has a sealing protrusion 65, which is located above the circumferential blocking protrusion 61, and the sealing protrusion 65 is used to seal the gap between the temperature-sensing positioning rod 64 and the cover body assembly 30, and the upper surface of the sealing protrusion 65 is located below the lower surface of the cover body assembly 30 and is arranged to fit the lower surface of the cover body assembly 30.

[0142] In the present application, the temperature-sensing positioning rod 64 has a central hole, into which a temperature-sensing element is placed. This protects the temperature-sensing element and prevents damage. It should be noted that, in the present application, the temperature-sensing element is a portion of the temperature-sensing element 60 and is the component within the temperature-sensing element 60 that senses temperature.

[0143] Optionally, the temperature sensing element is a thermocouple.

[0144] Example 4

[0145] like Figures 17 to 27 As shown, the cooking utensil includes a pot cover 10 and a pot body. The pot cover 10 can be opened and closed on the pot body. The pot cover 10 includes a cover assembly 30, a baking assembly 40 and an inner cover 50. The baking assembly 40 is arranged in the cover assembly 30 and includes a first reflector 441 and a second reflector 442. The inner cover 50 is detachably arranged below the baking assembly 40, and the first reflector 441 is located between the second reflector 442 and the inner cover 50.

[0146] By simultaneously installing the baking assembly 40 and the inner cover 50 on the pot lid 10, the cooking appliance can be used for both baking and pressure cooking. Since the inner cover 50 is detachably positioned below the baking assembly 40, when the cooking appliance is used for baking, the inner cover 50 is removed, allowing the baking assembly 40 to toast the food inside the pot. When the cooking appliance is used for pressure cooking, the inner cover 50 is installed below the baking assembly 40, sealing the high-pressure gas inside the pot for pressure cooking. The first reflector 441 in the baking assembly 40 reflects heat generated by the baking assembly 40 back into the pot, reducing the amount of heat transferred upwards to the lid assembly 30 and minimizing the impact of heat on components within the lid assembly 30. The second reflector 442, located closer to the lid assembly 30 than the first reflector 441, provides secondary protection for the lid assembly 30, further reducing heat transfer to the lid assembly 30 and increasing its operational stability.

[0147] Specifically, an air isolation layer is formed between the second reflector 442 and the first reflector 441. The provision of the air isolation layer prevents the first reflector 441 from directly contacting the second reflector 442, thereby increasing the time it takes for heat to be transferred to the second reflector 442. Some heat is dissipated while passing through the air isolation layer, reducing the amount of heat transferred to the second reflector 442 and further protecting the cover assembly 30.

[0148] It should be noted that the first reflector 441 and the second reflector 442 are both cap-shaped structures. The first reflector 441 and the second reflector 442 are connected and fixed at the cap brim and are spaced apart at the cap body to form an air isolation layer.

[0149] Optionally, the air insulation layer is greater than 6 mm. Limiting the air insulation layer to greater than 6 mm ensures that the air insulation layer can effectively cool the hot air, ensuring that the heat of the hot air is reduced after being transferred to the lid assembly 30 without affecting the lid assembly. It should be noted that the aforementioned air insulation layer greater than 6 mm refers to a thickness of the air insulation layer greater than 6 mm. Of course, the air insulation layer should not be too thick to avoid increasing the space occupied by the pot lid 10.

[0150] like Figure 17 and Figure 18As shown, the cover assembly 30 further includes a sealing structure 130, which is disposed between the cover assembly 30 and the second reflector 442. The provision of the sealing structure 130 can reduce heat transfer between the second reflector 442 and the cover assembly 30, thereby reducing the amount of heat transferred to the cover assembly 30, thereby protecting the cover assembly 30. It can also reduce heat loss in the baking assembly 40, thereby enabling the baking assembly 40 to bake quickly, shortening the cooking time and increasing the cooking efficiency of the cooking appliance.

[0151] like Figure 17 and Figure 20 As shown, the inner cover 50 has a pressure-limiting valve seat 52 and a check valve seat 53 that extend sequentially toward the cover assembly 30, and the first reflector 441 and the second reflector 442 are both provided with a through hole 444 for avoiding the pressure-limiting valve seat 52 and the check valve seat 53, and the sealing structure 130 is provided corresponding to the through hole 444. The pressure-limiting valve seat 52 and the check valve seat 53 extend into the cover assembly 30 through the through hole 444. The sealing structure 130 is provided corresponding to the through hole 444 and is located between the second reflector 442 and the cover assembly 30, sealing the gap between the through hole 444 and the second reflector 442 to prevent heat from entering the cover assembly 30 through the gap between the through hole 444 and the second reflector 442. The provision of the sealing structure 130 reduces the impact of hot air on the cover assembly 30 and increases the stability of the cover assembly 30.

[0152] like Figure 17 As shown, the sealing structure 130 is located between the pressure-limiting valve seat 52 and the check valve seat 53. This arrangement can prevent the pressure-limiting valve seat 52 and the check valve seat 53 from shaking, thereby increasing the working stability of the pressure-limiting valve seat 52 and the check valve seat 53.

[0153] like Figures 24 to 26 As shown, the sealing structure 130 includes a main body 132 and a limiting foot 131. The main body 132 further has a pressure-limiting valve seat extension hole 133 and a check valve seat extension hole 134. The pressure-limiting valve seat 52 on the inner cover 50 is connected to the pressure-limiting valve 120 through the pressure-limiting valve seat extension hole 133, and the check valve seat 53 on the inner cover 50 is connected to the check valve 190 through the check valve seat extension hole 134. The limiting foot 131 extends from the main body 132. The limiting foot 131 is engaged with the cover assembly 30 to limit the position. The limiting foot 131 is arranged along the circumference of the sealing structure 130. The limiting foot 131 is connected to the cover assembly 30 to prevent the sealing structure 130 from separating from the cover assembly 30, thereby increasing the tightness of the connection between the sealing structure 130 and the cover assembly 30. The sealing structure 130 seals the gap between the pressure-limiting valve seat 52 and the through hole 444, and also seals the gap between the stop valve seat 53 and the through hole 444 to reduce the heat transferred to the cover assembly 30 and prevent high-temperature gas from affecting the internal components of the cover assembly 30.

[0154] like Figure 25 As shown, the limiting foot 131 includes a connecting section 137, a reinforcement section 138, and an extension section 139, which are connected in sequence. The connecting section 137 is connected to the main body 132 to ensure a stable connection between the limiting foot 131 and the main body 132. The reinforcement section 138 is a variable diameter structure, and the diameter of the variable diameter structure decreases from the connecting section 137 to the extension section 139. The extension section 139 is connected to the cover assembly 30 to prevent the sealing structure 130 from being separated from the cover assembly 30, thereby increasing the tightness of the connection between the sealing structure 130 and the cover assembly 30.

[0155] like Figures 24 to 26 As shown, the main body 132 has a first circumferential stop ridge 135 surrounding the pressure-limiting valve seat extension hole 133, and the main body 132 also has a second circumferential stop ridge 136 that prevents the valve seat extension hole 134 from opening. The first circumferential stop ridge 135 and the second circumferential stop ridge 136 abut against the cover assembly 30 to stabilize the sealing structure 130 and seal the through hole 444.

[0156] like Figure 17 、 Figure 18 and Figure 20 As shown, the baking assembly 40 further includes a support structure 48, and the second reflector 442 is connected to the first reflector 441 via the support structure 48. The support structure 48 is located between the first reflector 441 and the second reflector 442. In this embodiment, the support structure 48 forms an air isolation layer between the first reflector 441 and the second reflector 442 to reduce the heat transferred to the second reflector 442.

[0157] like Figures 21 to 23 As shown, the inner cover 50 has a pressure-limiting valve seat 52 and a check valve seat 53 that extend sequentially toward the cover assembly 30. The support structure 48 has a pressure-limiting valve seat limiting hole 481 and a check valve seat limiting hole 482 for the pressure-limiting valve seat 52 and the check valve seat 53 to pass through. The pressure-limiting valve seat limiting hole 481 has a first annular rib 483 that extends toward the pressure-limiting valve seat 52, and the check valve seat limiting hole 482 has a second annular rib 484 that extends toward the check valve seat 53. In other words, the support structure 48 is sleeved on the pressure-limiting valve seat 52 and the check valve seat 53, and the provision of the first annular rib 483 and the second annular rib 484 can prevent the pressure-limiting valve seat 52 and the check valve seat 53 from shaking, thereby increasing the operational stability of the pressure-limiting valve seat 52 and the check valve seat 53. Furthermore, the provision of the first annular rib 483 and the second annular rib 484 also allows for a certain degree of tolerance in the assembly between the support structure 48 and the pressure-limiting valve seat 52 and the check valve seat 53. The provision of the support structure 48 also reduces the effect of heat within the baking assembly 40 on the pressure-limiting valve seat 52 and the check valve seat 53, thereby protecting the pressure-limiting valve seat 52 and the check valve seat 53.

[0158] like Figure 19 and Figure 20 As shown, the baking assembly 40 further includes a heating element 41, which is offset from the through hole 444. This prevents the heating element 41 from blocking the through hole 444 and also prevents the heating element 41 from radiating heat directly into the through hole 444, thereby reducing the impact of heat on the sealing structure 130.

[0159] like Figure 19 and Figure 20 As shown, the tubular structure of the heating element 41 is zigzag and coiled. The zigzag and coiled tubular structure can increase the heat transfer area of ​​the heating element 41, thereby reaching the required temperature in a short time, shortening the heating time and achieving the function of rapid baking.

[0160] In the present invention, the inner cover 50 is detachably connected to the baking assembly 40 via the positioning nut 80, so that the cooking appliance can switch between baking cooking and high-pressure cooking.

[0161] Example 5

[0162] like Figures 28 to 35 As shown, the baking assembly for the cooking utensil includes a heat-insulating combination cover 44, a heating element 41 and a protective net 42 arranged in sequence from top to bottom. A clip structure 45 is provided on the heat-insulating combination cover 44, and the protective net 42 is clipped to the clip structure 45. The heat-insulating combination cover 44 includes a first reflective cover 441 and a second reflective cover 442. The first reflective cover 441 is connected to the second reflective cover 442 via the clip structure 45.

[0163] By providing a snap-fit ​​structure 45 in the baking assembly, the protective net 42 is more easily mounted on the insulation assembly cover 44, increasing the convenience of installation. Furthermore, the protective net 42 and insulation assembly cover 44 are removable, making them easy to clean, keeping the baking assembly 40 clean and ensuring that meals cooked in the cooking appliance are more delicious and safe. Furthermore, the snap-fit ​​structure 45 is simple and easy to manufacture, resulting in low production costs and does not increase the cost of the baking assembly 40. Furthermore, the snap-fit ​​structure 45 secures the first reflector 441 and the second reflector 442, ensuring a tight connection between them.

[0164] like Figure 35 As shown, the bayonet 451 of the snap-fit ​​structure 45 faces downward, and at least a portion of the guard net 42 extends into the bayonet 451. The bayonet 451 is provided so that the guard net 42 is snapped into the snap-fit ​​structure 45 to be connected to the heat insulation assembly cover 44 through the snap-fit ​​structure 45.

[0165] like Figure 35As shown, the front end of the bayonet 451 is also provided with a guide inlet 452, and the opening area of ​​the guide inlet 452 gradually decreases in the direction approaching the bayonet 451. The guide inlet 452 is provided to guide the protective net 42 as it extends into the bayonet 451, so that the protective net 42 can be quickly inserted into the bayonet 451, making the installation between the protective net 42 and the clamping structure 45 more convenient. In addition, the provision of the guide inlet 452 provides positioning for the protective net 42 when it is installed in the clamping structure 45, thereby reducing the possibility of misalignment between the protective net 42 and the clamping structure 45. The opening area of ​​the guide inlet 452 gradually decreases in the direction approaching the bayonet 451, so that the protective net 42 is not easily dislodged from the bayonet 451 after it is in the bayonet 451, thereby increasing the stability of the connection between the protective net 42 and the clamping structure 45.

[0166] like Figure 35 As shown, the snap-fit ​​structure 45 includes a base section 453 and two snap-fit ​​plate sections 454 extending from a set of opposing side edges of the base section 453. The two snap-fit ​​plate sections 454 first approach each other to form a snap-fit ​​notch 451 and then move away from each other to form a guide entrance 452. The base section 453 supports the protective net 42, ensuring a stable connection between the protective net 42 and the snap-fit ​​structure 45. The snap-fit ​​plate sections 454 serve to stop the protective net 42 and prevent it from slipping out of the snap-fit ​​notch 451. The snap-fit ​​plate sections 454 first approach each other to form the snap-fit ​​notch 451 and then move away from each other to form the guide entrance 452. This arrangement not only accurately guides the protective net 42 into the snap-fit ​​notch 451 but also prevents it from slipping out of the snap-fit ​​notch 451. Since the snap-fit ​​structure 45 is formed by a sheet metal part made of elastic material, the snap-fit ​​plate section 454 has a certain deformation amount. The distance between the two snap-fit ​​plate sections 454 at the connection between the snap-fit ​​451 and the guide entrance 452 is the smallest, which can ensure that the protective net 42 will not fall out after being inserted into the snap-fit ​​451, thereby increasing the tightness of the connection between the protective net 42 and the snap-fit ​​structure 45.

[0167] like Figures 31 to 35 As shown, the clamping structure 45 includes a fixed end and a clamping end, the fixed end is fixedly connected to the heat insulation assembly cover 44, and the clamping end is clamped with the protective net 42. This arrangement allows the protective net 42 to be stably connected to the heat insulation assembly cover 44, increasing the stability of the connection between the protective net 42 and the heat insulation assembly cover 44.

[0168] like Figures 31 to 35As shown, the clamping structure 45 includes a connecting leg 455 extending toward the heat insulation assembly cover 44. The heat insulation assembly cover 44 is provided with a locking position 443. The connecting leg 455 is inserted into the locking position 443 and then bent. The connecting leg 455 extends into the locking position 443 to connect the first reflector 441 and the second reflector 442. The clamping structure 45 is fixed to the heat insulation assembly cover 44, thereby increasing the stability of the connection between the clamping structure 45 and the heat insulation assembly cover 44. Inserting the connecting leg 45 into the heat insulation assembly cover 44 and then bending it can reduce the possibility of separation of the clamping structure 45 from the heat insulation assembly cover 44, and can also reduce the shaking of the clamping structure 45, thereby avoiding unstable operation of the heating element 41.

[0169] Specifically, the latching position 443 is a through hole.

[0170] like Figure 30 and Figure 34 As shown, there are multiple snap-fit ​​structures 45, which are spaced apart along the circumference of the heat insulation assembly cover 44. The multiple snap-fit ​​structures 45 can be connected to the heat insulation assembly cover 44 at multiple locations, and can also be connected to the protective net 42 at multiple locations, allowing the protective net 42 to be installed more smoothly on the heat insulation assembly cover 44, reducing the situation where both the protective net 42 and the heating element 41 are installed tilted. At the same time, the multiple locations provide support for the protective net 42 and the heating element 41, reducing the possibility of the protective net 42 and the heating element 41 falling.

[0171] Optionally, the clip structure 45 is formed by bending a sheet metal member made of an elastic material. The elastic clip structure 45 has a good deformation capacity, making the clip structure 45 highly versatile and providing good error tolerance for the protective net 42 assembled thereon, thereby allowing a larger margin of error during the manufacturing process of the protective net 42. Of course, the clip structure 45 can also be formed of other elastic materials with greater strength.

[0172] like Figure 30 As shown, the circumference of the protective net 42 cooperates with the circumferential inner surface stop of the thermal insulation combination cover 44. This arrangement can prevent the protective net 42 from shaking in the thermal insulation combination cover 44, affecting the use of the heating element 41. In addition, it can also reduce the shaking of the protective net 42, reduce the collision of the protective net 42 with the thermal insulation combination cover 44, and increase the service life of the thermal insulation combination cover 44. The circumference of the protective net 42 cooperates with the circumferential inner surface stop of the thermal insulation combination cover 44, so that the circumferential inner surface of the thermal insulation combination cover 44 provides partial support for the protective net 42, which can indirectly share the force applied by the protective net 42 to the clamping structure 45, and increase the tightness of the connection between the protective net 42 and the thermal insulation combination cover 44.

[0173] The cooking utensil includes a pot cover 10 and a pot body. The pot cover 10 can be opened and closed on the pot body. The pot cover 10 includes a cover assembly 30, the above-mentioned baking assembly 40 and an inner cover 50. The second reflector 442 of the baking assembly 40 is located between the first reflector 441 of the baking assembly 40 and the cover assembly 30. The inner cover 50 is detachably arranged below the baking assembly 40.

[0174] By simultaneously providing the baking assembly 40 and the inner cover 50 within the cooking appliance, the cooking appliance can be used for both baking and high-pressure cooking, achieving a balanced cooking experience. This increases the functionality of the cooking appliance and provides the user with a better cooking experience. The first reflector 441 and the second reflector 442 within the baking assembly 40 reduce the amount of heat generated by the baking assembly 40 being transferred to the cover assembly 30, thereby increasing the stability of the cover assembly 30.

[0175] like Figure 29 and Figure 34 As shown, the heat-insulating cover assembly 44 includes a first reflector 441 and a second reflector 442. The second reflector 442 is disposed between the first reflector 441 and the cover assembly 30. The first reflector 441 is positioned near the heating element 41, reflecting heat emitted by the heating element 41 into the pot, thereby reducing the impact of high temperatures on the cover assembly 30. An air layer is provided between the first reflector 441 and the second reflector 442, thereby reducing the transfer of heat from the first reflector 441 to the second reflector 442. The second reflector 442 primarily provides insulation, reducing heat transfer into the cover assembly 30. The dual insulation provided by the first reflector 441 and the second reflector 442 significantly reduces the impact of the baking assembly 40 on the cover assembly 30, thereby increasing the operational stability of the cover assembly 30 and enhancing the stability and safety of the cooking appliance.

[0176] Example 6

[0177] like Figure 45 As shown, the upper surface of the inner cover 50 has a pressure-limiting valve seat 52, and the inner cover 50 also includes a pressure-limiting sealing ring 100, which is arranged on the pressure-limiting valve seat 52, and a first thermal insulation gap is formed between the pressure-limiting sealing ring 100 and the lower edge of the pressure-limiting sealing ring 100 and the bottom end of the pressure-limiting valve seat 52.

[0178] By placing the pressure-limiting seal ring 100 on the pressure-limiting valve seat 52 and making it removable along with the inner cover 50, the pressure-limiting seal ring 100 is protected from other structural components and prevented from melting and deformation due to high temperatures, thereby increasing the service life of the pressure-limiting seal ring 100. A first thermal insulation gap is formed between the lower edge of the pressure-limiting seal ring 100 and the bottom end of the pressure-limiting valve seat 52 to reduce the transfer of heat from the inner cover 50 to the pressure-limiting seal ring 100, thereby increasing the service life of the pressure-limiting seal ring 100.

[0179] Specifically, the first thermal insulation gap is greater than 10 mm. This arrangement can reduce the heat transfer from the lower portion of the inner cover 50 to the pressure limiting sealing ring 100, thereby increasing the service life of the pressure limiting sealing ring 100.

[0180] like Figure 57 As shown, the pressure-limiting sealing ring 100 is disposed in the middle of the pressure-limiting valve seat 52; or the distance between the pressure-limiting sealing ring 100 and the top of the pressure-limiting valve seat 52 is smaller than the distance between the pressure-limiting sealing ring 100 and the base of the pressure-limiting valve seat 52. This arrangement is intended to form a first thermal insulation gap between the pressure-limiting sealing ring 100 and the bottom of the pressure-limiting valve seat 52, and facilitate the pressure-limiting sealing ring 100 to seal the hole that needs to be sealed.

[0181] like Figure 56 As shown, the pressure-limiting seal ring 100 includes a ring body 101 and a retaining rib 102. The retaining rib 102 extends from the outer circumference of the ring body 101 toward the cover assembly 30. The inner and outer ring surfaces of the retaining rib 102 tilt upward from the ring body 101 and approach each other. The inner ring of the ring body 101 is closer to the center of the pressure-limiting seal ring 100 than the inner ring of the retaining rib 102. At least a portion of the ring body 101 is inserted into the pressure-limiting valve seat 52 and forms a stop between the ring body 101 and the pressure-limiting valve seat 52, preventing the pressure-limiting seal ring 100 from falling and enhancing the sealing stability of the pressure-limiting seal ring 100. The provision of the retaining rib 102 facilitates the installation of the pressure-limiting seal ring 100 and increases its convenience. Furthermore, the retaining rib 102 will stop other structural components, reducing the impact of other structural components on the pressure-limiting valve seat 52 and enhancing the safety of the pressure-limiting valve seat 52. The inner and outer surfaces of the limiting rib 102 are tilted upward and close to each other, facilitating the removal and installation of the pressure-limiting sealing ring 100. The surface of the pressure-limiting sealing ring 100 facing the inner cover 50 is flat and fits in contact with at least a portion of the pressure-limiting valve seat 52, thereby enhancing the stability of the seal between the pressure-limiting sealing ring 100 and the pressure-limiting valve seat 52.

[0182] like Figure 57 As shown, the pressure limiting valve seat 52 is provided with an installation groove, and the pressure limiting sealing ring 100 is clamped in the installation groove. This arrangement can increase the tightness of the connection between the pressure limiting sealing ring 100 and the pressure limiting valve seat 52, so that the pressure limiting sealing ring 100 can be removed together with the inner cover 50.

[0183] like Figure 45 、 Figure 48 and Figure 49 As shown, the upper surface of the inner cover 50 has a check valve seat 53. The inner cover 50 also includes a check valve seal 110. The check valve seal 110 is mounted on the check valve seat 53, and a second thermal insulation gap is formed between the lower edge of the check valve seal 110 and the bottom end of the check valve seat 53. The check valve seal 110 is mounted on the check valve seat 53 and is removable along with the inner cover 50. This prevents the check valve seal 110 from being affected by other structural components and from melting and deforming due to high temperatures, thereby extending the service life of the check valve seal 110. The first thermal insulation gap is formed between the lower edge of the check valve seal 110 and the bottom end of the check valve seat 53 to reduce the transfer of heat from below the inner cover 50 to the check valve seal 110, thereby extending the service life of the check valve seal 110.

[0184] Specifically, the second thermal insulation gap is greater than 10 mm. This arrangement can reduce the heat transfer from the lower portion of the inner cover 50 to the anti-opening sealing ring 110, thereby increasing the service life of the anti-opening sealing ring 110.

[0185] like Figure 60 As shown, the distance between the stop seal ring 110 and the top of the stop valve seat 53 is smaller than the distance between the stop seal ring 110 and the base of the stop valve seat 53; alternatively, the stop seal ring 110 is positioned at the top of the stop valve seat 53. In other words, the stop seal ring 110 is positioned slightly above the center of the stop valve seat 53 or at the top of the stop valve seat 53. This arrangement creates a second thermal insulation gap between the stop seal ring 110 and the bottom of the stop valve seat 53 and facilitates the stop seal ring 110 sealing the desired aperture.

[0186] like Figure 59 As shown, the stop seal ring 110 has a tapered section 111. The provision of the tapered section 111 facilitates installation of the stop seal ring 110. The surface of the stop seal ring 110 facing the inner cover 50 is flat and fits in contact with at least a portion of the stop valve seat 53, reducing the possibility of separation between the stop seal ring 110 and the stop valve seat 53.

[0187] In this embodiment, the anti-opening sealing ring 110 and the pressure-limiting sealing ring 100 are separate, which reduces the mutual influence between the two. However, the assembly is complicated and it is not easy to install them in place at the same time.

[0188] Of course, the anti-opening sealing ring 110 and the pressure-limiting sealing ring 100 are integrally formed (not shown in the figure). Such an arrangement can reduce the installation steps of the anti-opening sealing ring 110 and the pressure-limiting sealing ring 100.

[0189] like Figures 36 to 61As shown, the cooking utensil includes a pot cover 10 and a pot body 20. The pot cover 10 can be opened and closed on the pot body 20. The pot cover 10 includes a cover assembly 30, a baking assembly 40 and the above-mentioned inner cover 50. A fan is provided in the cover assembly 30. The baking assembly 40 is arranged in the cover assembly 30. The inner cover 50 is detachably arranged below the baking assembly 40.

[0190] By simultaneously installing the baking assembly 40 and the inner lid 50 within the cooking appliance, the cooking appliance can be used for both baking and pressure cooking. Since the inner lid 50 is removably mounted below the baking assembly 40, when the cooking appliance is to be used for baking, the inner lid 50 is removed, allowing the baking assembly 40 to bake the food inside the pot. When the cooking appliance is to be used for pressure cooking, the inner lid 50 is installed below the baking assembly 40, sealing the high-pressure gas within the pot, thereby enabling high-pressure cooking of the food inside the pot 20. The pressure-limiting valve seat 52 provides a mounting location for the pressure-limiting valve 120. The pressure-limiting sealing ring 100 is mounted on the pressure-limiting valve seat 52 and is removable along with the inner lid 50. This prevents the baking assembly 40 from burning the pressure-limiting sealing ring 100, preventing it from melting and deforming due to the high heat, thereby increasing its service life. A first thermal insulation gap is formed between the lower edge of the pressure-limiting seal ring 100 and the bottom end of the pressure-limiting valve seat 52 to reduce the transfer of heat from the pot body 20 to the pressure-limiting seal ring 100, thereby increasing the service life of the pressure-limiting seal ring 100. A fan within the cover assembly 30 can dissipate heat transferred to the cover assembly 30, thereby reducing the temperature of the cover assembly 30 and increasing the stability of the components within the cover assembly 30.

[0191] It should be noted that in the present application, the cover assembly 30 has a first plug-in terminal 31, and the pot body 20 has a second plug-in terminal 21 that cooperates with the first plug-in terminal 31. The first plug-in terminal 31 and the second plug-in terminal 21 are plugged together to supply power to the pot cover 10. This coupled power supply method can reduce deformation and make the power supply more stable.

[0192] like Figure 46 As shown, the pressure-limiting sealing ring 100 of the inner cover 50 is in sealing engagement with the pressure-limiting valve mounting hole 33 of the cover assembly 30, and the anti-opening sealing ring 110 of the inner cover 50 is in sealing engagement with the anti-opening valve mounting hole 34 of the cover assembly 30. The pressure-limiting sealing ring 100 passes through the baking assembly 40 to seal the pressure-limiting valve mounting hole 33 of the cover assembly 30, and the pressure-limiting sealing ring 100 passes through the baking assembly 40 to seal the anti-opening valve mounting hole 34 of the cover assembly 30.

[0193] like Figure 46 and Figure 47As shown, the baking assembly 40 includes a heat-insulating assembly cover 44, a heating element 41, and a plurality of fixing clips 49, which are arranged sequentially from top to bottom. The heating element 41 is mounted on the heat-insulating assembly cover 44 via the fixing clips 49, and the pressure-limiting valve seat 52 of the inner cover 50 passes through the fixing clips 49. The heating element 41 avoids the pressure-limiting valve seat 52. The heat-insulating assembly cover 44 has a pressure-limiting valve seat clearance hole 445 for the pressure-limiting valve seat 52 to pass through. The baking assembly 40 bakes the food inside the pot body 20 by generating heat from the heating element 41. The heat-insulating assembly cover 44 isolates the heat generated by the baking assembly 40 to prevent heat from being transferred to the cover assembly 30. The provision of the pressure-limiting valve seat clearance hole 445 allows the pressure-limiting valve seat 52 to pass through the heat-insulating assembly cover 44 and penetrate into the cover assembly 30. The plurality of fixing clips 49 secure the heating element 41 in multiple positions, increasing the stability of the connection between the heating element 41 and the heat-insulating assembly cover 44.

[0194] like Figure 46 and Figure 47 As shown, the cover assembly 30 includes a face cover 35 and an inner liner 36, with a sealing ring provided between the face cover 35 and the inner liner 36. The sealing ring seals the through hole on the face cover 35 through which the pressure limiting valve seat 52 passes, thereby reducing damage to the internal components of the cover assembly 30.

[0195] In a specific embodiment not shown in the figure, the baking component 40 has a protective net, and the heating element 41 is connected to the thermal insulation combination cover 44 through the protective net, rather than being fixed to the thermal insulation combination cover 44 by a fixing clip. The contact area between the protective net and the heating element 41 is large, making the connection between the heating element 41 and the thermal insulation combination cover 44 tighter.

[0196] exist Figure 46 and Figure 47 In the illustrated embodiment, the pot lid 10 further includes a handle 140 and a steam cover 150. The handle 140 and steam cover 150 are connected to the surface cover 35 of the lid assembly 30. At least a portion of the handle 140 is connected to the rotating rod 37 on the lining 36 to drive the rotating cover 170 to rotate, thereby opening and closing the pot lid 10 and the pot body 20. The steam cover 150 is spaced apart from the handle 140 and shields the pressure limiting valve 120 to prevent the pressure limiting valve 120 from disengaging from the pressure limiting valve seat 52.

[0197] In the present application, the cover assembly 30 further includes thermal insulation cotton 160 , which is located between the lining 36 and the thermal insulation combination cover 44 to reduce the heat transfer from the baking assembly 40 to the lining 36 , thereby increasing the stability of the cover assembly 30 .

[0198] When the stop-open sealing ring 110 and the pressure-limiting sealing ring 100 are integrally formed (not shown in the figure), the stop-open sealing ring 110 and the pressure-limiting sealing ring 100 can be installed at the same time to the pressure-limiting valve mounting hole 33 and the stop-open valve mounting hole 34 on the cover assembly 30, saving installation time and increasing the convenience of assembly of the cooking utensil.

[0199] Example 7

[0200] like Figures 62 to 65 As shown, the pressure cooking appliance includes a pot cover 10 and a pot body. The pot cover 10 can be opened and closed on the pot body. The pot cover 10 includes a cover assembly 30, a baking assembly 40 and an inner cover 50. The baking assembly 40 is arranged in the cover assembly 30. The baking assembly 40 also includes a heating element 41 and a protective net 42 arranged in sequence from top to bottom, and the protective net 42 is detachably arranged. The inner cover 50 is detachably arranged below the baking assembly 40, and the inner cover 50 has a pressure limiting assembly extending toward the cover assembly 30.

[0201] By arranging the baking assembly 40 and the inner cover 50 on the pot lid 10, the pressure cooking apparatus can perform both baking and pressure cooking. Since the inner cover 50 is removably mounted below the baking assembly 40, when the pressure cooking apparatus is required to bake, the inner cover 50 is removed, allowing the baking assembly 40 to bake the food inside the pot. When the pressure cooking apparatus is required to perform pressure cooking, the inner cover 50 is installed below the baking assembly 40, sealing the high-pressure gas inside the pot and allowing pressure cooking of the food inside. Since the baking assembly 40 bakes the food inside the pot using heat generated by the heating element 41, dirt easily accumulates on the protective screen 42 during long-term use. The removable protective screen 42 facilitates cleaning. It should be noted that the pressure limiting assembly includes a pressure limiting valve.

[0202] like Figure 63 and Figure 65 As shown, the protective net 42 includes a limiting structure 421, and the heating element 41 is engaged with the limiting structure 421 for limiting position. The provision of the limiting structure 421 allows the protective net 42 and the heating element 41 to be connected more tightly, and the engagement between the heating element 41 and the limiting structure 421 can reduce the shaking of the heating element 41, thereby preventing the protective net 42 from colliding with the heating element 41, thereby increasing the stability of the heating element 41 during use and increasing the stability and safety of the pressure cooking appliance. The fitting arrangement between the heating element 41 and the protective net 42 allows the protective net 42 to support and protect the heating element 41, preventing the heating element 41 from falling and also preventing other structures from colliding with the heating element 41.

[0203] exist Figure 65In the specific embodiment shown, the protective net 42 also includes a protective net body 422, and the limiting structure 421 is a limiting rib extending outward from the protective net body 422, and at least one section of the limiting rib is bent to form a limiting section. The limiting section and the protective net body 422 are located on different planes and form a clamping gap, and at least a portion of the heating element 41 is located in the clamping gap. The protective net body 422 supports the heating element 41 to prevent the heating element 41 from falling. The setting of the limiting section can form a stop for the heating element 41 to prevent the heating element 41 from shaking on the protective net 42, affecting the assembly of the heating element 41 and the protective net 42. The setting of the clamping gap provides positioning for the heating element 41 to be assembled on the protective net 42, so that the heating element 41 can be accurately assembled on the protective net 42.

[0204] like Figure 65 As shown, the protective net body 422 of the protective net 42 includes at least one annular protective rib 423 and at least one positioning connecting rib 424. Each positioning connecting rib 424 is connected to at least one annular protective rib 423, and the heating element 41 is connected to the annular protective rib 423 and / or the positioning connecting rib 424. The annular protective rib 423 can protect the heating element 41, blocking other structural parts that may affect the heating element 41 from the outside, thereby avoiding damage to the heating element 41. Each positioning connecting rib 424 is connected to at least one annular protective rib 423, so that the annular protective rib 423 and the positioning connecting rib 424 form a whole, which is convenient for removing and installing the protective net 42. The positioning connecting rib 424 is used to connect the protective net 42 to other structures so that the baking component 40 can work stably. In addition, the positioning connecting rib 424 and the annular protective rib 423 jointly support the heating element 41 to prevent the heating element 41 from falling.

[0205] Specifically, the end of at least one positioning connecting rib 424 extends toward the cover assembly 30 after passing through the annular protective rib 423 to serve as a connecting end. This arrangement reduces the connection area between the protective net 42 and other structural components, reducing the difficulty of assembling the protective net 42. The protective net 42 is connected to other components via the connecting end, so that the protective net 42 and the heating element 41 are positioned in a specific position.

[0206] like Figure 65As shown, there are multiple positioning and connecting ribs 424, spaced circumferentially around the annular protective rib 423. The protective net body 422 also includes reinforcing ribs 425, with at least one pair of adjacent positioning and connecting ribs 424 connected by the reinforcing ribs 425. The multiple positioning and connecting ribs 424 can connect to other structural components at multiple locations to prevent the protective net 42 from falling. The multiple positioning and connecting ribs 424 also provide increased support for the heating element 41, preventing it from falling or tilting. The provision of the reinforcing ribs 425 increases the structural strength of the positioning and connecting ribs 424, reduces separation between the positioning and connecting ribs 424 and other structural components or the annular protective rib 423, and thereby enhances the stability of the protective net 42. Furthermore, the use of the positioning and connecting ribs 424 and reinforcing ribs 425 to connect to other structural components and support the heating element 41 reduces the weight of the protective net 42, making the pressure cooking device thinner and lighter, and making it easier to move.

[0207] like Figure 65 As shown, the guard net 42 further includes a limiting rib, at least a portion of which is connected to at least one of the annular protective rib 423, the positioning connection rib 424, and the reinforcing rib 425. The heating element 41 is engaged with the limiting rib to limit its position, so that the heating element 41 fits on the guard net 42. This arrangement allows the limiting rib to be more tightly connected to the guard net body 422, so that the position between the limiting rib and the guard net body 422 is relatively fixed, thereby accurately positioning and engaging the heating element 41.

[0208] like Figure 64 As shown, the baking assembly 40 also includes a reflector 43 positioned above the heating element 41. The outer ring of at least one annular protective rib 423 abuts against the circumferential inner surface of the reflector 43. The reflector 43 reflects heat emitted by the heating element 41 into the pot body, thereby reducing the transfer of heat generated by the heating element 41 to the lid assembly 30 and thereby reducing damage to components within the lid assembly 30. The abutment between the outer ring of the at least one annular protective rib 423 and the circumferential inner surface of the reflector 43 prevents the protective net 42 from swaying within the reflector 43, which could affect the use of the heating element 41. Furthermore, the swaying of the protective net 42 is reduced, thereby minimizing impacts on the reflector 43 and increasing the service life of the reflector 43.

[0209] It should be noted that in this embodiment, there are two annular protective ribs 423, both of which are concentrically arranged with the reflector 43 and nested concentrically. The outer annular protective rib 423 acts as a stop against the circumferential inner surface of the reflector 43, ensuring that the protective net 42 and the reflector 43 do not move in any direction after they are properly installed. The inner annular protective rib 423 is provided to facilitate the handling of the protective net 42 when removing and installing the protective net 42.

[0210] like Figure 63 As shown, the baking assembly 40 also includes a reflector 43 positioned above the heating element 41. A protective screen 42 is connected to the cover assembly 30 via the reflector 43. Both the protective screen 42 and the reflector 43 are detachable. This arrangement facilitates cleaning of the reflector 43 and the protective screen 42. When cleaning the protective screen 42 and the reflector 43 is necessary, the protective screen 42 can be removed and cleaned separately. Because the reflector 43 is smooth, it can be cleaned simply by wiping it with a damp cloth, significantly enhancing the cleanliness of the baking assembly 40.

[0211] Specifically, the protective net 42 is snap-fitted to the reflector 43. The reflector 43 has a plurality of snap-fit ​​positions, and the protective net 42 is detachably snapped into the snap-fit ​​positions. The snap-fit ​​arrangement facilitates assembly and disassembly of the protective net 42 and the reflector 43, and ensures that the positions of the protective net 42 and the reflector 43 are relatively fixed.

[0212] Optionally, the pressure cooking device is an electric pressure cooker. Of course, the pressure cooking device can also be other electrical appliances for cooking food, such as a pressure rice cooker.

[0213] It should be noted that, in the above embodiment, the reflective cover 43 and the heat-insulating combination cover 44 are at the same position. The difference between the two is that the heat-insulating combination cover 44 has multiple reflective layers, such as the first reflective cover and the second reflective cover mentioned in the above embodiment, while the reflective cover 43 is a single-layer reflective cover. Of course, the reflective cover can also be a reflective layer and other materials that do not have a reflective effect.
