Description

Technical Field

[0001] This application relates to the technical field of kitchen equipment, and in particular to a low-oil frying and grilling cooking device. Background Technology

[0002] In food processing equipment such as air fryers, microswitches are usually installed inside the machine to reduce safety hazards. These switches are used to identify whether the pot components are in place, thus preventing the equipment from continuing to heat when the pot components are removed.

[0003] A patent with authorization announcement number CN221101900U discloses a micro switch and spring shaft mounting structure for an air fryer, including a body and a pot body. One side of the body has an opening, forming a cooking cavity for placing the pot body. A reflector plate is provided on the top of the cooking cavity of the body. A bracket is fixedly installed on the upper surface of the reflector plate at the opening. A micro switch is fixedly installed on the surface of the bracket. Guide plates are provided on both sides of the micro switch's spring shaft on the lower surface of the bracket. An inclined plate with an open opening is provided on the outer end of the guide plate. A limiting groove for inserting two guide plates is provided on the inner side of the top of the pot body. An abutment part is formed between the two limiting grooves. The end of the abutment part is an abutment slope that cooperates with the micro switch.

[0004] The above solution achieves the positioning detection of a single pot by mounting a micro switch on a bracket on a reflector plate, and has certain practicality in single-pot air fryer products.

[0005] However, with increasing user demand for multi-functional and large-capacity devices, air fryers with multiple pots have emerged. If the existing technology is directly applied, microswitches must be installed on the same support frame corresponding to the position of each pot, and the support frame supporting these microswitches is mounted on a reflector. Since the reflector is usually made of thin metal sheet and is not the main load-bearing structure of the device, when the cooking cavity volume increases to accommodate the multi-pot design, the reflector area needs to be enlarged accordingly, further reducing its structural rigidity and making it prone to deformation. Simultaneously, the load from multiple microswitches further exacerbates the deformation of the reflector. This deformation is directly transmitted to the support frame, causing misalignment of the mounting planes and relative positions of the microswitches, leading to poor contact, unstable triggering, and other problems, severely affecting the triggering accuracy of the microswitches. Furthermore, the deformation of the reflector can damage the sealing structure between the head housing and the reflector cover, causing hot air from the cooking cavity to leak through the gaps, reducing heating efficiency and potentially scalding users, further amplifying safety hazards. Summary of the Invention

[0006] In order to effectively solve the above-mentioned technical problems, this application provides a low-oil frying and grilling cooking device.

[0007] This application provides a low-oil frying and grilling cooking device, which adopts the following technical solution: A low-oil frying and grilling cooking device includes a lower shell and an upper shell fastened to the lower shell. The upper shell is equipped with a hot air circulation device and a downward-facing reflector. The lower shell is equipped with a cooking cavity that can accommodate at least two pot body components. The cooking cavity has a door frame for the pot body components to enter and exit. The door frame is formed by the upper shell and the lower shell. The pot body component includes a pot body. At least two micro switch components are provided at the door frame. A first mounting bracket is provided at the lower port of the upper shell, and the upper shell is fixedly connected to the first mounting bracket. A second mounting bracket that cooperates with the first mounting bracket is provided on the pot body. The micro switch components include a micro switch and a corresponding trigger. The micro switch is located on the first mounting bracket, and the trigger is located on the second mounting bracket.

[0008] Optionally, the pot body assembly further includes a protective plate located on the front side of the pot body, the protective plate forming a second mounting bracket; or, the pot body assembly further includes a protective plate located on the front side of the pot body, the second mounting bracket being located above the protective plate.

[0009] Optionally, the width of the first mounting bracket is 25-40mm.

[0010] Optionally, a notch is provided on the front side of the lower port of the upper housing, and the first mounting bracket is located at the notch, forming part of the lower port of the upper housing.

[0011] Optionally, the lower port of the upper housing has an inwardly extending flange at least on the front side, and the first mounting bracket covers the flange of the upper housing.

[0012] Optionally, the first mounting bracket is L-shaped; or, the first mounting bracket is straight.

[0013] Optionally, the reflector has at least a skirt extending outward on its front side, and the first mounting bracket is disposed on the skirt; or, the reflector has at least a skirt extending outward on its front side, and the flange of the upper shell is disposed on the skirt.

[0014] Optionally, the first mounting bracket is provided with a rearwardly extending rim that covers the top of the reflector.

[0015] Optionally, the first mounting bracket has rearward extensions at both ends, and the length of the extensions is less than 1 / 3 of the depth of the reflector.

[0016] Optionally, a cold air cavity is provided inside the upper housing and above the reflector, a cold air space is provided inside the protective plate, and a ventilation port is provided on the first mounting bracket to connect the cold air cavity and the hot air space.

[0017] Optionally, at least two reflectors and hot air circulation devices are provided. The pot assembly includes a first pot and at least one second pot. The size of the first pot is larger than that of the second pot. A first micro switch assembly is provided between the first mounting bracket and the first pot, and a second micro switch is provided between the first mounting bracket and the second pot.

[0018] In summary, this application has at least the following beneficial effects: 1. When the pot assembly is pushed into the cooking cavity of the lower shell and positioned, the first and second mounting brackets precisely engage, allowing the trigger to stably activate the microswitch. When the pot assembly is removed, the trigger disengages from the microswitch, and the cooking equipment immediately stops heating, significantly improving the accuracy of pot assembly positioning. Furthermore, by installing at least two microswitch assemblies at the door frame, along with the corresponding design of the first and second mounting brackets, independent and accurate detection of multiple pot assemblies is achieved. The first mounting bracket can flexibly arrange the corresponding number of microswitch assemblies according to product needs, adapting to multi-pot assembly equipment with different capacities and functional combinations.

[0019] The mounting base of the micro switch is transferred from the reflector to the first mounting bracket fixedly connected at the lower port of the upper housing. The upper housing, as the main load-bearing structural component of the equipment, has a structural strength far exceeding that of the thin reflector. It can provide a stable mounting foundation for the first mounting bracket and multiple micro switches, fundamentally eliminating the problems of micro switch mounting plane offset and relative position misalignment caused by reflector deformation. Because the mounting base is stable, each micro switch and the trigger on the corresponding pot body component can accurately correspond after the equipment is assembled, completely solving the core defects of poor contact and unstable triggering caused by reflector deformation in the prior art.

[0020] The reflector no longer needs to bear the mechanical load of the first mounting bracket and multiple microswitches, minimizing its potential deformation. This effectively maintains the integrity of the seal between the reflector and the upper housing, preventing the leakage of hot air from the cooking chamber and fundamentally eliminating the risk of burns to users, thus improving the safety of the equipment. Furthermore, the reflector maintains a good fit with the pot assembly, effectively ensuring the sealing of the cooking chamber, reducing heat loss during cooking, and thereby improving the heat utilization rate and cooking efficiency of the equipment. Simultaneously, the stable sealed environment ensures uniform temperature within the cooking chamber, ensuring consistent food temperature within the pot assembly, further enhancing the cooking effect of low-oil frying and grilling.

[0021] The second mounting bracket is formed by using the protective plate on the front side of the pot body. The trigger is placed on the protective plate. Its structure is stable and moves synchronously with the pot body, which can ensure that the relative position of the trigger and the pot body is fixed, thereby ensuring that the alignment accuracy of the micro switch and the trigger is always stable. At the same time, the second mounting bracket and the protective plate are integrated into the design, eliminating the need for an additional independent mounting structure, simplifying the overall structure of the pot body assembly, and reducing processing and assembly costs.

[0022] The width of the first mounting bracket is 25-40mm, which can provide sufficient and stable installation space for the micro switch. This avoids the problem of unstable micro switch fixation and trigger position displacement caused by the first mounting bracket being too narrow. It also avoids the first mounting bracket being too wide, which would occupy the space of the reflector or make the upper housing too wide. This achieves a high-strength and functionally integrated layout in a compact space. Attached Figure Description

[0040] The present application will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that the embodiments are merely specific illustrations of the present application, and their purpose is to enable those skilled in the art to better understand the technical solutions of the present application, and should not be regarded as limitations on the present application.

[0041] In the description of this application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Example 1

[0042] This application discloses a low-oil frying and grilling cooking device, such as... Figure 1 , Figure 3 and Figure 4 As shown, the device includes an upper shell 1, a lower shell 2, and a pot assembly 3. The upper shell 1 is fastened to the lower shell 2, and the upper shell 1 and the lower shell 2 can be integrally formed or set separately. The upper shell 1 is provided with a hot air circulation device 11 and a downward-facing reflector 12. The hot air circulation device 11 includes a heating element 111, a first fan blade 112, and a drive motor 113 that drives the first fan blade 112 to rotate. The heating element 111 and the first fan blade 112 are located inside the reflector 12. The lower shell 2 is provided with a cooking cavity 21 that can accommodate at least two pot assemblies 3. The cooking cavity 21 has a door frame for the pot assemblies 3 to enter and exit. The door frame is formed by the upper shell 1 and the lower shell 2. The pot body assembly 3 includes a pot body 31, at least two micro switch assemblies 5 are provided at the door frame, a first mounting bracket 4 is provided at the lower port of the upper housing 1, and the upper housing 1 is fixedly connected to the first mounting bracket 4. The pot body assembly 3 is provided with a second mounting bracket 32 ​​that cooperates with the first mounting bracket 4. The micro switch assembly 5 includes a micro switch 51 and a corresponding trigger 52. The micro switch 51 is disposed on the first mounting bracket 4, and the trigger 52 is located on the second mounting bracket 32.

[0043] In this embodiment, either two small pots or one large pot can be placed inside the cooking cavity 21. The volume of the large pot is the same as the volume of the two small pots. That is, the large pot and the two small pots can be interchangeably installed inside the cooking cavity 21, allowing users to flexibly choose according to their cooking needs, thus enhancing the versatility of the cooking equipment and the user experience. Figure 5 The micro switch assembly 5 has two micro switches 51, which are located on the left and right sides of the first mounting bracket 4, respectively. Each of the two small pots has a trigger 52, and the large pot has two triggers 52. When the large pot is placed into the cooking cavity 21, the two triggers 52 on the large pot will trigger the corresponding micro switches 51 at the same time. When the two small pots are placed into the cooking cavity 21, the triggers 52 on the small pots will trigger the corresponding micro switches 51.

[0044] When the pot body assembly 3 is pushed into the cooking cavity 21 of the lower shell 2 and is in place, the first mounting bracket 4 and the second mounting bracket 32 ​​can cooperate precisely, so that the trigger 52 can stably trigger the micro switch 51; when the pot body assembly 3 is removed, the trigger 52 and the micro switch 51 are disengaged in time, and the cooking equipment can immediately stop heating, which significantly improves the accuracy of recognizing the position of the pot body assembly 3.

[0045] By setting at least two micro-switch assemblies 5 at the door frame, and in conjunction with the corresponding design of the first mounting bracket 4 and the second mounting bracket 32, independent and accurate detection of multiple pot body assemblies 3 is achieved. Furthermore, the first mounting bracket 4 can flexibly arrange the corresponding number of micro-switch assemblies 5 according to product needs, and can adapt to multi-pot body assembly equipment with different capacities and functional combinations.

[0046] The mounting base of the micro switch 51 is transferred from the reflector 12 to the first mounting bracket 4, which is fixedly connected at the lower port of the upper housing 1. The upper housing 1, as the main load-bearing structural component of the equipment, has a structural strength far exceeding that of the thin reflector 12. It can provide a stable mounting foundation for the first mounting bracket 4 and multiple micro switches 51, fundamentally eliminating the problem of micro switch 51 mounting plane offset and relative position misalignment caused by the deformation of the reflector 12. Because the mounting base is stable, each micro switch 51 and the corresponding trigger 52 on the pot assembly 3 can accurately correspond after the equipment is assembled, completely solving the core defects of poor contact and unstable triggering caused by the deformation of the reflector 12 in the prior art.

[0047] The reflector 12 no longer needs to bear the mechanical load of the first mounting bracket 4 and multiple microswitches 51, minimizing its potential deformation. This effectively maintains the integrity of the sealing structure between the reflector 12 and the upper housing 1, preventing the leakage of high-temperature hot air from the cooking chamber 21 and fundamentally eliminating the risk of burns to the user, thereby improving the safety of the equipment. Furthermore, the reflector 12 maintains a good fit with the pot assembly 3, effectively ensuring the sealing of the cooking chamber 21, reducing heat loss during cooking, and thus improving the heat utilization rate and cooking efficiency of the cooking equipment. Simultaneously, the stable sealing environment ensures the uniformity of temperature in the cooking chamber 21, ensuring consistent food intake within the pot assembly 3, further enhancing the cooking effect of low-oil frying and grilling.

[0048] It should be noted that the pot body assembly 3 also includes a protective plate 33 located on the front side of the pot body 31. The protective plate 33 forms a second mounting bracket 32, on which the trigger 52 is set. When the pot body 31 is pushed into the cooking cavity 21, the movement trajectory of the protective plate 33 is completely synchronized with the pot body 31, ensuring that the trigger 52 can always maintain a precise correspondence with the micro switch 51 on the first mounting bracket 4. In addition, the protective plate 33 can cover and seal the front opening of the cooking cavity 21, which can prevent the heat inside the pot body 31 from escaping.

[0049] The protective plate 33 is equipped with a handle 34, which allows users to push and pull the pot body 31 by holding the handle 34, preventing users from being burned when taking out or putting in the pot body 31, while also improving the convenience of operation.

[0050] The first mounting bracket 4 is arranged along the length of the upper housing 1, and the width of the first mounting bracket 4 is 25-40mm. This provides sufficient and stable installation space for the micro switch 51, avoiding the problem of unstable fixing and trigger position displacement of the micro switch 51 due to the first mounting bracket 4 being too narrow. It also avoids the first mounting bracket 4 being too wide, which would occupy the space of the reflector 12 or make the upper housing 1 too wide, thus achieving a high-strength and functionally integrated layout in a compact space.

[0051] When the first mounting bracket 4 is set along the length of the upper shell 1 and supports the microswitches 51 on both sides, its structure is equivalent to a large-span beam. When the pot body 31 is pushed in, the trigger 52 applies pressure to the microswitches 51, which may generate torsional load. If the strength of the first mounting bracket 4 is insufficient, it is very easy for it to bend or torsion to occur in the middle, resulting in the mounting planes of the two microswitches 51 not being coplanar and the trigger point position shifting, which seriously affects the triggering accuracy of the microswitches 51 on both sides and the sealing between the first mounting bracket 4 and the upper shell 1. The width of 25-40mm provides the cross-sectional dimensions for this long strip component, giving it sufficient strength to resist bending and torsional deformation. The stable first mounting bracket 4 ensures that the mounting bases of the two microswitches 51 on both sides are firm and their relative positions remain accurate and unchanged, realizing the positioning detection of multiple pot body components 3.

[0052] Furthermore, when the pot body 31 is pushed in, the guard plate 33 can slide smoothly along the width direction of the first mounting bracket 4. The 25-40mm width design ensures that the first mounting bracket 4 has sufficient guiding contact area, which can not only ensure guiding stability, but also prevent the frictional resistance of pushing the pot body 31 in from being too wide due to the first mounting bracket 4 being too wide, thus improving the user experience.

[0053] In this embodiment, combined with Figure 6 The trigger 52 is a groove located on the top of the guard plate 33, which extends to the rear side of the guard plate 33. The micro switch 51 includes a switch body 511 and a micro spring shaft 512. The micro spring shaft 512 is vertically downward and passes through the lower surface of the first mounting bracket 4. The bottom of the micro spring shaft 512 is hemispherical. When the pot body 31 is inserted into the cooking cavity 21, the micro spring shaft 512 corresponds to the groove. The guard plate 33 drives the trigger 52 to move synchronously. The bottom wall of the groove presses against the micro spring shaft 512 of the micro switch 51. The micro spring shaft 512 moves upward. When the pot body 31 is fully in place, the micro switch 51 is triggered, and the heating program can be started.

[0054] The lower port of the upper housing 1 has a notch on the front side, that is, there is a notch between the lower port of the upper housing 1 and the front side of the reflector 12. The first mounting bracket 4 is located at the notch and forms part of the lower port of the upper housing 1. The first mounting bracket 4 has at least two first mounting holes 411. The upper housing 1 has a downwardly extending connecting post 13. The connecting post 13 has a second mounting hole 131 corresponding to the first mounting hole 411. The first mounting hole 411 and the corresponding second mounting hole 131 are provided with bolts or other locking components to fix the first mounting bracket 4 to the upper housing 1.

[0055] The notch design provides dedicated installation space for the first mounting bracket 4. Once embedded in the notch, the first mounting bracket 4 directly forms part of the lower port of the upper housing 1, ensuring the continuity of the overall structure of the upper housing 1. Simultaneously, the locking mechanism ensures a stable structure between the first mounting bracket 4 and the upper housing 1, enhancing the structural strength and deformation resistance of the lower port of the upper housing 1. Furthermore, it avoids obstructing the installation space of the reflector 12, preventing structural interference between the first mounting bracket 4 and the reflector 12. The first mounting bracket 4 fills the structural gap caused by the notch, further optimizing the sealing performance of the cooking cavity 21, reducing heat loss from the port gaps during cooking, and improving heat utilization and cooking efficiency.

[0056] The reflector 12 has an outwardly extending skirt 121 on at least its front side. The first mounting bracket 4 is partially placed on top of the skirt 121, which can improve the sealing between the first mounting bracket 4 and the reflector 12. The extended structure of the skirt 121 fills the assembly gap between the first mounting bracket 4 and the reflector 12, preventing hot air from leaking out from the gap between the two. At the same time, the first mounting bracket 4 is partially placed on top of the skirt 121, and the structural pressure of the first mounting bracket 4 itself makes the skirt 121 fit more tightly with the first mounting bracket 4, forming a sealed and pressed structural effect.

[0057] It should be noted that, in combination Figure 2 The first mounting bracket 4 is L-shaped, comprising a vertically arranged first connecting part 42 and a horizontally arranged second connecting part 43. The rear side of the second connecting part 43 rests on the skirt 121 of the reflector 12. A micro switch 51 is mounted on the second connecting part 43. The width of the second connecting part 43 is 25-40mm, and it is connected to the upper housing 1 via a locking device. The first connecting part 42 is fitted against the front side of the reflector 12. Furthermore, the top of the first connecting part 42 has a rearwardly extending rim 44 that covers the reflector 12, further improving the seal between the reflector 12 and the first mounting bracket 4, reducing heat loss, and improving cooking efficiency and effect. The first connecting part 42, the second connecting part 43, and the rim 44 are integrally formed, which improves the strength and precision of the first mounting bracket 4.

[0058] A frame 45 is provided on the second connecting part 43 and located around the micro switch 51. While strengthening the first mounting bracket 4 itself, it can also position the micro switch 51.

[0059] The skirt 121 of the reflector 12 can be used as the mounting and positioning reference for the second connecting part 43. The mating surface between the first connecting part 42 and the front side of the reflector 12 can be used as the vertical positioning reference. During assembly, the first mounting bracket 4 can be placed according to the mating and overlapping position relationship to quickly complete the accurate positioning.

[0060] Bolts or other locking components are provided between the top of the reflector 12 and the surrounding edge 44, and the locking components are located at the corners of the surrounding edge 44. This allows for the positioning of the first mounting frame 4, and when it cooperates with the upper housing 1, it improves the connection stability of the first mounting frame 4. During equipment operation, even under the influence of vibration from the hot air circulation device 11 and thermal expansion and contraction caused by temperature changes, the first mounting frame 4 can be prevented from loosening or shifting. This ensures that the installation position of the micro switch 51 on the second connection part 43 is precise and controllable, and that the alignment accuracy with the trigger 52 of the guard plate 33 remains consistent, guaranteeing trigger reliability. Furthermore, the locking components between the reflector 12 and the surrounding edge 44 apply a downward preload, ensuring a tight fit between the surrounding edge 44 and the reflector 12, reducing the gap between them, and preventing hot air leakage from the gap between the first mounting frame 4 and the reflector 12.

[0061] A reinforcing plate 46 is provided between the first connecting part 42 and the second connecting part 43, which can further improve the structural strength of the first mounting frame 4 itself. The reinforcing plate 46 can disperse the stress concentration at the corner of the L-shaped structure, and avoid slight deformation of the first mounting frame 4 due to uneven force during installation or locking, thereby consolidating the positioning accuracy. The locking component forms a connected whole between the first mounting frame 4, the reflector 12, and the upper housing 1. Together with the reinforcing plate 46 between the first connecting part 42 and the second connecting part 43, it further strengthens the strength of the first mounting frame 4 itself, so that the three components are subjected to force in a coordinated manner and the first mounting frame 4 itself is not easily damaged. It avoids fatigue damage caused by a single component bearing the load independently, extends the service life of the first mounting frame 4, the reflector 12, and the micro switch 51, and improves the overall structural durability and long-term operational reliability of the equipment.

[0062] The bottom of the second connecting part 43 is provided with a downwardly extending abutment plate 47, and the skirt 121 is located behind the abutment plate 47. When the pot body 31 is placed in place, the guard plate 33 is located in front of the abutment plate 47. The top of the pot body 31 is provided with an outwardly extending pot rim 35. The abutment plate 47 corresponds to the boundary of the pot rim 35, ensuring that the hot air generated by the hot air circulation device 11 can enter the pot body 31 under the guidance of the reflector 12, and heat the food in the pot body 31 evenly.

[0063] Furthermore, the top surface of the second connecting part 43 and the front end are provided with an upwardly extending guide block 48. The front side of the guide block 48 and the top are provided with an inclined surface 481. When the upper housing 1 is installed, the inclined surface 481 can play a guiding role, so that the lower port of the upper housing 1 can be quickly aligned with the installation position of the first mounting bracket 4. The guide block 48 can assist the upper housing 1 to be quickly placed, shortening the assembly time. After the guide block 48 guides the upper housing 1 to be placed, the guide block 48 abuts against the upper housing 1, so that the upper housing 1 and the first mounting bracket 4 fit more tightly. With the subsequent fixing of the locking parts, the sealing and stability of the connection between the two are further improved.

[0064] In other embodiments, the first mounting bracket 4 can also be arranged in a straight line, with the rear side of the first mounting bracket 4 resting on the skirt 121, which can provide installation space for the micro switch 51 and also meet the sealing requirements between the first mounting bracket 4 and the reflector 12.

[0065] The first mounting bracket 4 has rearwardly extending extensions 49 at both its left and right ends. These extensions 49 fit snugly against the skirt 121 of the reflector 12, and are connected to the skirt 121 via locking devices. This widens the lateral force-bearing range of the first mounting bracket 4, increases its overall strength, and enhances the sealing effect between the first mounting bracket 4 and the reflector 12, reducing the risk of hot air leakage from the gaps on both sides of the first mounting bracket 4, improving the sealing of the cooking cavity 21, and reducing heat loss. Furthermore, the length of the extensions 49 is less than one-third of the depth of the reflector 12, ensuring lateral support and sealing while preventing excessive length from interfering with the rear end of the reflector 12, thus reducing production costs.

[0066] The left and right extensions 49 can also serve as a lateral positioning reference for the first mounting bracket 4 and the reflector 12 to fit together, and can quickly calibrate the left and right positions of the first mounting bracket 4 during assembly to avoid lateral offset.

[0067] It should be noted that the lower shell 2 is provided with an inner liner with a front opening. The inner liner and the reflector 12 together form the cooking cavity 21. Support frames are provided on both the left and right sides of the front end of the inner liner. The extension 49 is connected to the inner liner and the support frames through locking parts, which can support the front end of the reflector 12, reduce the deformation of the reflector 12, and keep the upper structure of the entire cooking cavity 21 highly stable, providing a reliable background environment for the precise triggering of the micro switch 51.

[0068] Combination Figure 7 and Figure 8A motor frame 14 is provided inside the upper housing 1 and above the reflector 12. A receiving cavity 15 communicating with the outside is provided between the upper housing 1 and the motor frame 14. The drive motor 113 is located on the motor frame 14. A cold air cavity 16 communicating with the receiving cavity 15 is provided between the reflector 12 and the motor frame 14. A second fan blade 17 connected to the drive motor 113 is provided in the cold air cavity 16. A cold air space 331 is provided in the guard plate 33. A vent 41 communicating with the hot air space is provided on the first mounting bracket 4. Driven by the second fan blade 17, external cold air enters the receiving cavity 15 and the cold air cavity 16 to cool the drive motor 113 and the parts inside the upper housing 1. At the same time, the cold air in the receiving cavity 15 enters the cold air space 331 inside the protective plate 33 through the vent 41 to cool the protective plate 33, preventing the protective plate 33 from deforming and affecting the fitting accuracy with the first mounting bracket 4, thereby ensuring the reliability of the micro switch 51 triggering and extending the service life of the protective plate 33 and the overall pot body 31 assembly 3.

[0069] Furthermore, the first mounting bracket 4 has both ventilation and heat insulation functions in the cold air circulation system. Its vent 41 connects the receiving cavity 15 and the cold air space 331, providing a directional flow channel for cold air. At the same time, with the sealing effect of the extension 49, the surrounding edge 44, and the guide block 48, it prevents cold air leakage from affecting the heat dissipation efficiency and also prevents hot air from the cooking cavity 21 from seeping back into the cold air system, ensuring that the heat dissipation path is precise and controllable. The first mounting bracket 4 forms a heat insulation barrier by fitting and overlapping with the reflector 12, which can effectively block the high temperature of the cooking cavity 21 from being conducted to the receiving cavity 15, preventing cooking heat from interfering with the heat dissipation effect. At the same time, it prevents high temperature from affecting the working stability of the micro switch 51 and can improve the cooling effect of the protective plate 33. Example 2

[0070] The difference between this embodiment and the above embodiments is that: Figure 9 As shown, the microswitch assembly 5 has three components. One microswitch 51 is located in the middle of the first mounting bracket 4, and the other two microswitches 51 are located on the left and right sides of the first mounting bracket 4, respectively. The tops of the two small pots are respectively equipped with trigger elements 52 corresponding to the microswitches 51 on the sides, and the middle of the large pot is equipped with a trigger element 52 corresponding to the microswitch 51 in the middle. When using two small pots, if either small pot is not pushed into place, its corresponding microswitch 51 will not be triggered. The device can then determine and prevent heating or only heat the small pot that is in place, thus achieving zoned safety control. When using the large pot configuration, the trigger element 52 on its top only needs to trigger the microswitch 51 in the middle to transmit a signal to the device that the large pot has been pushed into place.

[0071] Users only need to place the corresponding pot 31 according to their cooking needs, and the device can identify which pot 31 is currently in use and call the corresponding control logic, which enhances the versatility and intelligence of the device. Example 3

[0072] The difference between this embodiment and the above embodiments is that: Figure 10 and Figure 11 As shown, the lower port of the upper housing 1 has an inwardly extending flange 18 at least on the front side. The first mounting bracket 4 covers the flange 18 of the upper housing 1. The reflector 12 has an outwardly extending skirt 121 at least on the front side. The flange 18 of the upper housing 1 rests on the skirt 121. The micro-motion spring shaft 512 of the micro switch 51 passes through the first mounting bracket 4 and the flange 18 to cooperate with the trigger 52 on the pot body 31. The flange 18 of the upper housing 1 provides a flat support surface for the first mounting bracket 4. With the fixed connection between the first mounting bracket 4 and the upper housing 1, the force on the first mounting bracket 4 is more even. At the same time, the rear side of the flange 18 rests on the skirt 121 of the reflector 12, so that the upper housing 1 receives auxiliary support from the reflector 12 through the skirt 121, which can improve the structural stability of the equipment and thus improve the triggering accuracy of the micro switch 51.

[0073] The overlap between the flange 18 and the skirt 121 fills the gap between the lower port of the upper housing 1 and the reflector 12. This, combined with the structure of the first mounting bracket 4 covering the flange 18, forms double protection. This, along with the top seal of the perimeter 44 and the side seal of the extension 49, reduces the possibility of hot air leakage from the overlap, minimizing heat loss. Simultaneously, the overlap between the flange 18 and the skirt 121 forms a heat-insulating buffer layer. Combined with the heat insulation effect of the first mounting bracket 4, this further reduces the conduction of high temperature from the cooking cavity 21 to the upper housing 1 and the receiving cavity 15, preventing high temperatures from affecting the operational stability of the components inside the upper housing 1 and the microswitch 51. Example 4

[0074] The difference between this embodiment and the above embodiment is that the pot body assembly 3 also includes a protective plate 33 located on the front side of the pot body 31. The second mounting bracket 32 ​​is located above the protective plate 33 and is fixed to the protective plate 33 by a locking member. That is, the second mounting bracket 32 ​​provides the trigger 52 with a mounting reference surface independent of the pot body 31, reducing the possibility of slight deformation or displacement of the protective plate 33. Since the second mounting bracket 32 ​​is firmly locked on the protective plate 33, the correspondence between the trigger 52 on it and the micro switch 51 on the first mounting bracket 4 remains constant. When the pot body 31 is pushed into place, the trigger 52 can accurately reach the same position and perform the triggering action, completely eliminating the risk of poor triggering caused by loosening of the front structure of the pot body 31.

[0075] Furthermore, the second mounting bracket 32, as an independent component, is connected to the guard plate 33 through a locking member. It can concentrate the reaction force of the micro switch 51 and distribute it to a wider area of ​​the guard plate 33 through the locking member. This can effectively prevent the guard plate 33 from deforming or fatigue damage due to long-term load bearing, ensuring that the guard plate 33 can be flatly attached to the door frame and guaranteeing the sealing between the guard plate 33 and the door frame. Example 5

[0076] The difference between this embodiment and the above embodiments is that: Figure 12 and Figure 13 As shown, at least two reflectors 12 and hot air circulation devices 11 are provided, and a detachable adapter 6 is also included. The adapter 6 is used to cooperate with the edge 35 of the small pot body to separate the adjacent hot air circulation devices 11 and make the reflectors 12 cooperate with the small pot body to form an independent cooking space. After the adapter 6 is removed, at least two reflectors 12 cooperate with the large pot body to form a cooking cavity 21.

[0077] In this embodiment, two sets of reflectors 12 and hot air circulation device 11 are provided. The two reflectors 12 can be set separately or integrally formed. The first mounting bracket 4 is placed horizontally on the front side of the two reflectors 12, and the middle part of the first mounting bracket 4 extends backward to the space between the two reflectors 12, which can play an auxiliary positioning role for the installation of the first mounting bracket 4, and facilitate the installation and fixation of the first mounting bracket 4.

[0078] The adapter 6 has a “∣” shaped structure or a T-shaped structure, and both the left and right sides of the adapter 6 have sliding grooves that mate with the rim of the small pot. In the partitioned mode, the adapter 6 is installed between the lower ports of the two reflectors 12, dividing the interior of the inner pot into two identical and independent cooking areas. At least one small pot extends into the corresponding cooking area. The adapter 6 engages with the rim 35 of the small pot, physically separating the adjacent cooking spaces. This not only effectively prevents crosstalk between different foods but also allows each reflector 12 and its corresponding small pot to form an independent heat circulation system, preventing heat loss and improving the independence and efficiency of cooking in the small pot. When using the large pot for overall cooking, the adapter 6 can be removed. There are no fixed obstacles in the cooking cavity 21, providing an unobstructed convergence and circulation channel for the airflow generated by the adjacent hot air circulation devices 11. This allows the hot air to mix and convect fully throughout the cooking cavity 21, and at least two hot air circulation devices 11 work together to heat the food in the large pot, forming a wider and more evenly distributed heat field. This ensures that the central area of ​​the large pot receives sufficient heat, enabling uniform heating of large-capacity food and significantly improving the overall cooking effect.

[0079] Combination Figure 14The adapter 6 is connected to the reflector 12 via a snap-fit ​​structure 7. The snap-fit ​​structure 7 includes a first hook 71 on the adapter 6. The first hook 71 includes a vertically arranged first fastening member 711 and a second fastening member 712 formed by bending the top of the first fastening member 711 forward or backward. The reflector 12 has a connection hole corresponding to the first hook 71, and the diameter of the connection hole is larger than the size of the second fastening member 712 so that the second fastening member 712 can pass through the connection hole. When the adapter 6 is aligned with the reflector 12 and the second fastening member 712 passes through the connection hole, the first fastening member 711 is located inside the connection hole. At this time, the adapter 6 is moved in the bending direction of the second fastening member 712 so that the second fastening member 712 rests on top of the reflector 12, thereby fixing the adapter 6 between the two reflectors 12.

[0080] In this embodiment, combined with Figure 15 The first hook 71 is located on the rear side of the adapter frame 6. To improve the connection stability of the adapter frame 6, the buckle structure 7 also includes a second hook 73 located at the bottom of the first mounting frame 4. The second hook 73 has an L-shaped structure and includes a third fastening member 731 and a fourth fastening member 732 formed by bending the bottom of the third fastening member 731. The top of the adapter frame 6 is open so that the second hook 73 can extend into the adapter frame 6. The adapter frame 6 is provided with a buckle 74 that cooperates with the second hook 73 and a driving member 75 that drives the buckle 74 to disengage from the second hook 73. The buckle 74 includes a first locking block 741 that engages with the second hook 73 and a second locking block 742 on the side of the first locking block 741 away from the second hook 73. A sliding rod that slides with the adapter frame 6 is provided on the side of the second locking block 742 away from the first locking block 741. An elastic member 743 is sleeved on the outside of the sliding rod. The elastic member 743 can be set as a spring. One end of the spring is connected to the second locking block 742 and the other end is connected to the adapter frame 6.

[0081] The driving component 75 has a rod-shaped structure with an inclined top and a bottom that extends through the bottom wall of the adapter 6. The bottom of the second locking block 742 is provided with a first inclined surface 744 that cooperates with the top of the driving component 75.

[0082] The top of the first locking block 741 is provided with a second inclined surface 745. When installing the adapter 6, no external force needs to be applied to the driving member 75. After aligning the first hook 71 with the connecting hole, the adapter 6 is moved directly upward. The buckle 74 moves under the guidance of the second hook 73 and the second inclined surface 745. After the second fastening member 712 passes through the connecting hole, the adapter 6 is moved forward or backward, so that the second fastening member 712 rests on the reflector 3. The buckle 74 returns to its original position under the elastic action of the elastic member 743, so that the first locking block 741 is locked above the fourth fastening part 732, thereby fixing the adapter 6 to the reflector 12 and the first mounting bracket 4, making the installation of the adapter 6 simpler and faster. When it is necessary to disassemble the adapter 6, push the driving member 75 upward to disengage the first locking block 741 from the fourth fastening member 732, move the adapter 6 in the opposite direction, and then move the adapter 6 downward to disassemble the adapter 6.

[0083] The overlapping of the first hook 71 and the elastic locking of the second hook 73 form a fixation at two points, greatly enhancing the connection stability of the adapter 6 and enabling fast and accurate installation.

[0084] Combination Figure 16 The first mounting bracket 4 is provided with a first micro switch 8 for detecting whether the adapter 6 is installed. The first micro switch 8 is located behind the middle micro switch 51. The first locking block 741 is provided with a first trigger corresponding to the first micro switch 8. When the adapter 6 is pushed to the final locked position, the first trigger on the first locking block 741 will press the first micro switch 8 to generate a signal that the adapter 6 has been installed.

[0085] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
