Description

Technical Field

[0001] This utility model relates to the field of food grilling devices, and more particularly to a multi-mode grill. Background Technology

[0002] Barbecue is a common cooking method that uses a heat source to directly or indirectly heat and grill food, resulting in a grilled flavor. It is especially suitable for occasions such as outdoor camping and gatherings with family and friends. To adapt to different usage scenarios and the heating methods and processing quantities of various ingredients, barbecue grills on the market come in different structural forms.

[0003] For example, some barbecue grills with openable lids can form a closed space when the lid is closed, improving heating efficiency; some barbecue grills also have heating elements such as heating tubes in the lid, which are laid flat with the grill body when the lid is open, and can provide an additional heating area and expand the heating working surface when the corresponding heating element is activated.

[0004] While existing barbecue grills can expand the heating area when the lid is open, the food on the grill body and lid is still heated from the bottom. In reality, the heating state and mode have not changed. During the cooking process, the food needs to be turned over constantly, resulting in low heating efficiency and relatively high requirements for manual operation. Utility Model Content

[0005] In the first aspect, embodiments of this application provide a multi-mode barbecue grill that solves the problems of existing barbecue grills having a single working mode and requiring high manual operation, so as to achieve different heating modes for food.

[0011] When the first furnace body and the second furnace body are in the half-open mode, the heat radiation direction of the third infrared heating tube is towards the first heating space.

[0012] Because of the above-mentioned solution, the multi-mode barbecue oven of this application embodiment can automatically determine whether it is in the closed mode, half-open mode, or open mode according to the relative angle of the first oven body and the second oven body, and thus execute the corresponding heating control mode. In the half-open mode, the infrared heating tube of the first heating module heats the food from the bottom, and one of the heating tubes of the second heating module heats the food from the top, thereby additionally realizing a working mode of double-sided heating of food in the half-open state of the barbecue oven, improving the heating efficiency of food and reducing manual operation.

[0054] It should be understood that if the controllers or control circuits involved in the embodiments are conventional control technologies or units for those skilled in the art, such as the control circuits of the controllers, they can be implemented by those skilled in the art using existing technologies.

[0055] The disclosure of the embodiments provides many different implementations or examples for different ways of implementing this utility. To simplify the disclosure of this utility, components and arrangements of specific examples are described in the embodiments. Of course, these are merely examples and are not intended to limit the utility. Furthermore, reference numerals and / or reference letters may be repeated in different examples in the embodiments; such repetition is for simplification and clarity and does not in itself indicate a relationship between the various implementations and / or arrangements discussed.

[0056] Combination Figures 1-5As shown, the first embodiment of the barbecue grill includes a first grill body 1 and a second grill body 2, and the first grill body 1 and the second grill body 2 are connected by a rotating shaft 3 to form an openable structure;

[0057] The opening and closing structure of the first furnace body 1 and the second furnace body 2 includes a closed mode position, a half-open mode position, and a fully open mode position positioned by the rotating shaft 3. The overall structure of this embodiment is a furnace body state that can be opened and closed, consisting of the first furnace body 1, the second furnace body 2, and the rotating shaft 3. In terms of specific structural composition, the first furnace body 1 includes a first shell 101, in which a first structural frame 102 is provided. The first structural frame 102 is a structural component that is lined inside the first shell 101. A first heating component 103 is installed in the first structural frame 102. The first heating component 103 has a first heating space 104 in the middle. The first heating component 103 includes an infrared heating tube, a reflector, a heat dissipation component, and a mounting... The structural assembly specifically includes a mounting support 105, which serves as the mounting base for other internal components. A first infrared heating tube 106 and a second infrared heating tube 107 are respectively installed on the mounting support 105 at positions opposite to each other in the first heating space 104. The first infrared heating tube 106 and the second infrared heating tube 107 are heated by thermal radiation. Thermal radiation is a form of heat transfer. When current passes through the resistance wire inside the heating tube, the resistance effect converts electrical energy into heat energy, causing the surface temperature of the heating tube to rise rapidly. The heating tube radiates energy outward in the form of electromagnetic waves, hence the term thermal radiation. The main wavelength is infrared, which can act on food to create a grilling heating state.

[0058] Reflectors 108 are respectively provided on the back sides of the first infrared heating tube 106 and the second infrared heating tube 107. The reflectors 108 reflect the infrared rays emitted by the first infrared heating tube 106 and the second infrared heating tube 107 towards the direction of the first heating space 104, thereby radiating heat to the food or the container holding the food placed in the first heating space 104. The emitted light from the reflectors 108 has the characteristic of diverging within a certain range towards the emission area.

[0059] In this embodiment, the first infrared heating element 106 and the second infrared heating element 107 are positioned on opposite sides of the first heating space 104, allowing the heat source area to be located on both sides of the food area, separating oil droplets and high-temperature heat sources, and effectively preventing the generation of oil fumes. Simultaneously, to isolate the food area from the first infrared heating element 106 and the second infrared heating element 107, transparent cover plates 109 are respectively provided on the mounting support 105 at the locations corresponding to the first infrared heating element 106 and the second infrared heating element 107. After the transparent cover plates 109 cover the first infrared heating element 106 and the second infrared heating element 107, the first infrared heating element 106 and the second infrared heating element 107 are enclosed on both sides of the mounting support 105.

[0060] Since the transparent cover 109 covers the installation area of ​​the first infrared heating tube 106 and the second infrared heating tube 107, the heat in the installation area of ​​the first infrared heating tube 106 and the second infrared heating tube 107 is difficult to dissipate quickly during operation, resulting in a high temperature in the corresponding area outside the machine. In order to avoid the accumulation of heat in the installation area of ​​the first infrared heating tube 106 and the second infrared heating tube 107, a heat dissipation structure can also be provided on the side of the first infrared heating tube 106 and the second infrared heating tube 107 to avoid excessive local shell temperature.

[0061] In this embodiment, the first heating space 104 can be used to hold food. To further facilitate the placement and collection of food, a first glass pot 110 is provided in the middle of the first structural frame 102. Based on the heating direction setting in this embodiment, the first glass pot 110 has an inclined surface corresponding to the positions of the first infrared heating tube 106 and the second infrared heating tube 107, and the heat radiation direction of the first infrared heating tube 106 and the second infrared heating tube 107 is inclined towards the corresponding inclined surface.

[0062] Preferably, in order to facilitate the placement and removal of the first glass pot 110, side ears 111 are provided on both sides of the first glass pot 110. At the same time, in order to prevent the side ears 111 of the first glass pot 110 from protruding from the overall surface when placed in the first structural frame 102, and to avoid affecting the closing of the first furnace body 1 and the second furnace body 2, a recess 112 is provided on the first structural frame 102 corresponding to the side ears 111 for accommodating the side ears 111.

[0063] The internal structure of the first furnace body 1 has been described in detail above. Correspondingly, the internal structure of the second furnace body 2 is generally the same as that of the first furnace body 1, including a main structure consisting of a second shell 201, a second structural frame 202, a second heating module 203, a second heating space 204, a third infrared heating tube 205, and a fourth infrared heating tube 206. The structural relationship of these components can be referred to the structural relationship in the first furnace body 1. After assembly, the second furnace body 2 is arranged opposite to the first furnace body 1 and connected by the rotating shaft 3.

[0064] The difference between the first furnace body 1 and the second furnace body 2 is as follows:

[0065] 1. For ease of control and operation, the first furnace body 1 is also equipped with a control panel 113, which includes control buttons, a display area and corresponding circuit boards. Since the second furnace body 2 is movable, it is generally not equipped with a control panel.

[0066] Second, since the second furnace body 2 has a downward opening structure, its second glass pot 207 needs to be fastened in the second furnace body 2 by means of a snap fastener.

[0067] 3. A transparent window 208 can be set on the upper surface of the second furnace body 2 for observing the internal food contents when the furnace is closed.

[0068] Other differences in shape, edge, or line that do not involve functionality can be adjusted according to design needs and will not be elaborated upon.

[0069] like Figure 6-8 As shown, after the first heating module and the second furnace body 2 of the above structure are installed in an openable and closable structure via the rotating shaft 3, in this embodiment, the first furnace body 1 and the second furnace body 2 have closed mode, open mode and half-open mode corresponding to the closed mode position, the flat mode position and the half-open mode position that can be positioned by the rotating shaft when working.

[0070] The above-mentioned closed mode position, open mode position and half-open mode position are set to meet the needs of common braised, grilled skewers and grilled meat modes, respectively. In addition to the different opening angles of the first oven body 1 and the second oven body 2, the three modes also involve differences in the corresponding heating methods, which will be explained in detail below.

[0071] Since the structure and function settings in the semi-open mode are significantly different from those of existing barbecue grills, the following will first explain the structure and function implementation in the semi-open mode.

[0072] like Figure 6As shown, in the semi-open mode, the first furnace body 1 is located below and is in a horizontal state. The second furnace body 2 is opened at an angle. In this angle state, the third infrared heating tube 205 of the second furnace body 2 is located near the area directly above the first glass pot 110, and its irradiation direction is towards the first heating space 104 or the first glass pot 110 therein. At this time, because the irradiation angle of the fourth infrared heating tube 206 in the second furnace body 2 is significantly deviated from the area where the first heating space 104 is located, the fourth infrared heating tube 206 is turned off. Therefore, in the semi-open mode, the first infrared heating tube 106 and the second infrared heating tube 107 in the first heating module heat the first heating space 104 from the side and below, and the third infrared heating tube 205 heats the top of the first heating space 104, forming simultaneous heating of the food placed in the first heating space 104 or the food placed on the surface of the first heating space 104 from both above and below. Meanwhile, in the semi-open mode, the gap between the first furnace body 1 and the second furnace body 2 can accommodate the movement of tools such as bamboo skewers and grilling nets placed on the surface of the first heating space 104, which are needed for processing grilled food.

[0073] Preferably, in the semi-open mode, the first infrared heating element 106 and the second infrared heating element 107 in the first heating module heat the bottom and sides of the first glass pot, while the third infrared heating element 205 heats the top of the first glass pot 110. At this time, there are two heat sources below the food, but only one heat source above it, which can easily cause uneven heating on the top and bottom surfaces. Therefore, in this embodiment, in the semi-open mode, the operating power of the third infrared heating element 205 is greater than the operating power of the first infrared heating element 106 or the second infrared heating element 107. The specific operating mode can be calculated based on the heating angle and heating distance to achieve the requirement of more consistent heating on the top and bottom surfaces in the semi-open mode.

[0074] like Figure 7 As shown, when the first furnace body 1 and the second furnace body 2 are in the closed mode position, the first heating space 104 and the second heating space 204 are combined into the furnace interior space, and the first heating module and the second heating module jointly heat the furnace interior space.

[0075] Preferably, since a transparent window 208 can be provided on the upper surface of the second oven body 2, the first infrared heating tube 106 and the second infrared heating tube 107 will emit a large amount of light outward from the transparent window 208, resulting in a higher temperature at the top of the grill. Therefore, in the closed mode, the working power of the first infrared heating tube 106 and the second infrared heating tube 107 is less than that of the third infrared heating tube 205 and the fourth infrared heating tube 206. The third infrared heating tube 205 and the fourth infrared heating tube 206 serve as the main heating source, while the first infrared heating tube 106 and the second infrared heating tube 107 serve as auxiliary heating sources.

[0076] like Figure 8 As shown, when the first furnace body 1 and the second furnace body 2 are in the open-type mode, the first infrared heating tube 106 and the second infrared heating tube 107 heat the first heating space 204, and / or the third infrared heating tube 205 and the fourth infrared heating tube 206 heat the second heating space.

[0077] Because of the above-mentioned solution, the multi-mode barbecue oven of this application embodiment can automatically determine whether it is in the closed mode, the open mode, or the half-open mode according to the relative angle of the first oven body and the second oven body, and thus execute the corresponding heating control mode. In the half-open mode, the infrared heating tube of the first heating module heats the food from the bottom, and one of the heating tubes of the second heating module heats the food from the top, thereby additionally realizing a working mode of double-sided heating of food in the half-open state of the barbecue oven, improving the heating efficiency of food and reducing manual operation.

[0078] The closed mode, open mode, and half-open mode positions are represented by the rotating shaft, serving two functional purposes. First, when the first furnace body 1 and the second furnace body 2 are in the closed mode, open mode, and half-open mode positions at a preset angle, the rotating shaft 3 can lock the first furnace body 1 and the second furnace body 2, keeping them in the corresponding mode positions. Second, the rotating shaft can provide feedback on the relative angle of the first furnace body 1 and the second furnace body 2 to determine whether they are in the accurate positions of the closed mode, open mode, and half-open mode, facilitating automated control. In this embodiment, the rotating shaft has both of the above functional purposes; that is, the rotating shaft 3 can both lock the first furnace body 1 and the second furnace body 2 in the closed mode, open mode, and half-open mode positions, and monitor and provide feedback on the relative angle of the first furnace body 1 and the second furnace body 2.

[0079] To achieve the above structure and function, embodiments of this application also provide a rotating shaft that can be manually locked and unlocked and provides angle feedback. In terms of the overall structure of the rotating shaft, it consists of a first shaft segment, a second shaft segment, and a third shaft segment, which are coaxially connected. During installation, the first shaft segment is connected to the second oven body (the upper oven body), and the second and third shaft segments are connected to the first oven body (the lower oven body). During the opening and closing of the first oven body, the first shaft segment rotates coaxially relative to the second and third shaft segments. The rotating shaft positions the opening and closing state of the first oven body. This positioning locks the angle of the first oven body at least in the half-open position, and also locks it in the closed and open positions as much as possible. Simultaneously, it provides feedback on the opening and closing angle of the first oven body so that the grill can perform the corresponding working state. To achieve the above functional requirements, a locking device and a locking plate are respectively provided in the first and second shaft segments. The locking device has a locking post protruding from its end face; the locking plate has a locking hole that mates with the locking post. To control the locking of the locking device and the locking plate, the locking device is connected to a locking device control component, which drives the locking device to engage or disengage from the locking plate for locking or unlocking. Additionally, to detect the rotation angle of the first shaft segment, an angle sensor can be installed between the first and second shaft segments, or between the first and third shaft segments. The specific location can be determined based on the layout of the installation space.

[0080] Based on the above overall structure of the rotating shaft, the following three embodiments illustrate the specific components and structural settings.

[0081] like Figures 9-11 As shown, the rotating shaft 3 in the second embodiment includes a first shaft segment 31, a second shaft segment 32, and a third shaft segment 33. In this embodiment, the first shaft segment 31 is connected to the second furnace body 2, and the second shaft segment 32 is connected to the first furnace body 1. The first shaft segment 31, the second shaft segment 32, and the third shaft segment 33 are coaxial and can rotate relative to each other.

[0082] The first shaft segment 31 includes a first bushing 311, a first inner shaft 312, and a locking device 313. The first bushing 311 is provided with a first retaining bar 314, the first inner shaft 312 is provided with a first retaining groove 315, and the locking device 313 is provided with a second retaining groove 316. The first bushing 311, the first inner shaft 312, and the locking device 313 achieve synchronous rotation through the cooperation of the first retaining bar 314, the first retaining groove 315, and the second retaining groove 316, and the locking device 313 can slide along the first retaining bar 314 in the first bushing 311.

[0083] The locking device 313 has a locking pin 317 on its outer side, and a locking spring 318 is provided between the first inner shaft 312 and the locking device 313. The locking device 313 is limited to the first bushing 311 by a locking device retaining ring 319. The locking device retaining ring 319 prevents the locking device 313 from coming out of the first bushing 311 when it slides horizontally.

[0084] The second shaft segment 32 includes a second bushing 321. The second bushing 321 has a locking piece 322 at one end near the locker 313. The locking piece 322 has a locking hole 323.

[0085] When the locking pin 317 is inserted into the locking hole 323, the rotation of the first shaft segment 31 and the second shaft segment 32 is locked. The insertion positions of the locking pin 317 and the locking hole 323 are set to lock the first shaft segment 31 and the second shaft segment 32. For example, when locking in the closed state of the first furnace body and the second furnace body, it is necessary to ensure that the locking pin 317 is inserted into the locking hole 323 at the corresponding angles of the first shaft segment 31 and the second shaft segment 32; when locking in the open state of the first furnace body and the second furnace body, it is necessary to ensure that the locking pin 317 is inserted into the locking hole 323 at the corresponding angles of the first shaft segment 31 and the second shaft segment 32; similarly, when locking in the half-open state of the first furnace body and the second furnace body, it is also necessary to ensure that the locking pin 317 is inserted into the locking hole 323 at the corresponding angles of the first shaft segment 31 and the second shaft segment 32. Based on the above requirements, at least three locking holes can be provided on the locking piece 322, and at least one locking pin 317 can be provided on the locking device 313.

[0086] The locking device 313 is connected to a locking device control assembly 34. The locking control assembly includes a rotating wheel 341, a rotating inner sleeve 342, and a transmission unlocking rod 343. The rotating inner sleeve 342 and the transmission unlocking rod 343 are respectively located at both ends of the rotating wheel 341. The rotating wheel 341 has a groove 344 located on the rotating inner sleeve. The rotating inner sleeve 342 has a slider 345 that cooperates with the groove 344. The groove 344 and the slider 345 are helically engaged. When the rotating inner sleeve 342 rotates, the engagement depth of the slider 345 in the groove 344 can be adjusted, thereby adjusting the relative distance between the rotating inner sleeve 342 and the rotating wheel 341.

[0087] When the rotating inner sleeve 342 rotates, the rotating wheel 341 is controlled to move horizontally through the cooperation of the slider 345 and the groove 344. The transmission unlocking rod 343 passes through the locking piece 322 and is connected to the locking device 313.

[0088] The rotating inner sleeve 342 is connected to a rotary handle 35, which is the locking and unlocking component, i.e., the operating component. By rotating the handle 35, the rotating inner sleeve 342 can be driven to rotate, thereby driving the locking device 313 to move horizontally.

[0089] The rotating wheel 341 is provided with a baffle 346, and the locking piece 322 is provided with a through hole 324 in the middle for the transmission unlocking rod 343 to pass through and connect to the locking device 313;

[0090] When unlocking, rotating the rotary handle 35 causes the rotating inner sleeve 342 to rotate accordingly. At this time, the slider 345 on the rotating inner sleeve 342 acts on the slide groove 344, thereby pushing the rotating wheel 341 to move towards the first inner shaft. At this time, the movement of the rotating wheel 341 applies a pushing force to the locking device 313 through the transmission unlocking rod 343, causing the locking pin 317 on the locking device 313 to disengage from the locking hole 323 on the card plate 322. At this time, the locking structure of the first shaft section 31 and the second shaft section 32 is disengaged. At this time, manipulating the second oven body 2 can adjust the opening and closing angle between the second oven body 2 and the first oven body 1, and adjust the barbecue oven to a closed state, a half-open state, or a fully open state as needed.

[0091] In the above-mentioned structural components, the rotary handle 35 is used to control unlocking and locking by rotating the angle. In fact, it can also be achieved by using a button, but since pressing the button requires applying a lateral thrust to the grill, it is easy to cause the grill to move. Therefore, the rotary handle 35 is preferred as the driving structure.

[0092] When locked, rotating the rotary handle 35 causes the rotating inner sleeve 342 to rotate synchronously. At this time, the slider 345 of the rotating inner sleeve 342 acts on the slide groove 344, thereby pulling the rotating wheel 341 towards the rotating inner sleeve 342. At this time, the rotating wheel 341 releases the thrust applied to the locking device 313 by the transmission unlocking rod 343. Under the elastic force of the locking spring 318, the locking device moves towards the locking piece 322, thereby causing the locking pin 317 on the locking device 313 to enter the locking hole 323 on the locking piece 322. At this time, the locking structure of the first shaft section 31 and the second shaft section 2 is locked and cannot rotate relative to each other. Since the first shaft section 31 is fixed on the second furnace body and the second shaft section 32 is fixed on the first furnace body, the opening and closing action between the second furnace body and the first furnace body stops and remains at this time.

[0093] In this embodiment, the rotating shaft further includes a third shaft segment 33, which is connected to the first furnace body. The third shaft segment 33 includes a damping component and a third bushing 331 fitted onto the damping component. When installed with the furnace body, the third bushing 331 is connected to the first furnace body 1. The third bushing 331 has a first mounting piece 332, and the corresponding end face of the first bushing 331 has a second mounting piece 333. A damping piece 334 is provided between the first mounting piece 332 and the second mounting piece 333. The damping piece causes the rotation of the second furnace body 2 to be subject to friction, preventing it from falling rapidly under gravity. This allows the second furnace body 2 to fall slowly without human intervention, avoiding collisions between furnace bodies and improving the user experience.

[0094] In this embodiment, a Hall sensor chip 335 is provided on the first mounting plate 332. The Hall sensor chip is a circuit chip with a Hall sensor. The rotation angle of the second furnace body 2 relative to the first furnace body 1 can be monitored through the Hall sensor chip 335, thereby executing the corresponding working mode.

[0095] The third embodiment provides a rotating shaft that electrically locks and unlocks and provides feedback on the angle.

[0096] like Figure 12 and Figure 13 As shown, similar to the second embodiment, the rotating shaft 3 of the third embodiment includes a first shaft segment 31, a second shaft segment 32, and a third shaft segment 33. In this embodiment, the first shaft segment 31 is connected to the second furnace body 2, the second shaft segment 32 is connected to the first furnace body 1, the first shaft segment 31 and the second shaft segment 32 are coaxial and can rotate relative to each other, and the third shaft segment 33 is connected to the first furnace body 1.

[0097] The first shaft segment 31 includes a first bushing 311, a first inner shaft 312, and a locking device 313. An electromagnet 3110 is provided in the first inner shaft 312. The electromagnet 3110 includes an electromagnet base 3111 and a movable spindle 3112 located in the electromagnet base. When the movable spindle 3112 is energized, it can move horizontally relative to the electromagnet base 3111. Adjusting the current direction can adjust the movement direction of the movable spindle 3112. The movable spindle 3112 is connected to and drives the locking device 313, thereby driving the locking device 313 to move in the horizontal direction.

[0098] In the third embodiment, the locking pin structure on the locker 313 and the card slot structure located on the second shaft segment 32, and the structural relationship between them during locking and unlocking, are the same as in the second embodiment, and will not be repeated here.

[0099] The fourth embodiment provides a rotating shaft that combines electric locking and unlocking with manual unlocking, so that the grill can be unlocked and opened in the event of an accidental power failure.

[0100] like Figures 14-15 As shown, in the fourth embodiment, the first shaft segment 31 includes a first bushing 311, in which a motor fixing sleeve 3113 is installed. A planetary geared motor 3114 is installed on the motor fixing sleeve 3113. The output end of the planetary geared motor 3114 is connected to a rotating wheel 3115. The outer wall of the rotating wheel 3115 is provided with an external thread 3116. A rotating outer sleeve 3117 is fitted onto the rotating wheel 3115. The inner wall of the rotating outer sleeve 3117 is provided with an internal thread 3118. The external thread 3116 and the internal thread 3118 cooperate to convert the forward and reverse circumferential rotation of the rotating wheel 3115 into the linear reciprocating motion of the rotating outer sleeve 3117. The outer end face of the rotating outer sleeve 3117 is connected to the locking device 313 through a connecting post 3119. Therefore, when the rotating outer sleeve 3117 is driven to perform linear reciprocating motion, it can push and pull the locking device 313 horizontally, thereby causing the locking device 313 to engage and disengage from the locking piece 322, achieving the purpose of electric locking and unlocking.

[0101] Furthermore, regarding the second shaft segment 32, it includes a manual unlocking mechanism. This mechanism comprises a pressing part 325, a pressing push rod 326, and an optical shaft 327 arranged sequentially. The optical shaft 327 passes through the locking piece 322, connects to the locking device 313, and rotates with the locking device 313. The pressing push rod 326 is movably sleeved or abuts against the contact end of the optical shaft 327. When the planetary geared motor 3114 fails to operate due to an unexpected power outage, manual operation can be performed to push the pressing part 325, advancing the pressing push rod 326 and the optical shaft 327. The optical shaft 327 then pushes the locking device 313 to move and disengage from the locking piece 322, thus restoring the first and second shaft segments 32 to an openable / closable state. This ensures that the first and second furnace bodies can be opened and closed smoothly even in the event of a power outage.

[0102] In terms of specific component structure, the locking device 313 has a cavity inside the mating direction of the connecting post 3119. The cavity has an internal depth length, which is used to ensure that the locking device 313 is not blocked by the connecting post 3119 when manually unlocking, thus providing displacement space and enabling smooth manual unlocking. At the same time, a first return spring 3120 is provided between the locking device 313 and the rotating outer sleeve 3117. When the manual pushing force is released, the return spring 3120 resets the locking device 313 and restores the displacement space. Correspondingly, in order to allow the pressing part 315 to reset when the driving force of manual pressing is lost, a second return spring 329 is provided between the pressing push rod 326 and the locking piece 322.

[0103] like Figure 16 As shown, in this embodiment, preferably, regarding the mating structure of the connecting post 3119 and the locking device 313, the end of the connecting post 3119 that mates with the locking device 313 is provided with one or more annular protrusions 3121, the opening of the cavity of the locking device 313 is provided with a notch 3122 that mates with the protrusions 3121, the cavity of the locking device 313 is provided with a mating groove 3123 that mates with the protrusions 3121, and the mating groove 3123 is offset from the notch 3122. After the end of the connecting post 3119 enters the cavity from the opening of the cavity, it rotates by an offset angle and aligns with the mating groove 3123 to form a mating.

[0104] The fifth embodiment of this application further provides a multi-mode barbecue oven capable of providing heating modes other than the above-mentioned baking mode, based on the first embodiment. Figure 17 As shown, a lower accommodating space is provided at the bottom of the first heating module inside the first furnace body 1. A side pull groove 41 is provided on one side of the lower accommodating space. A side pull heating plate 42 is provided in the lower accommodating space. The side pull heating plate 42 is pulled out along the side pull groove or stored at the bottom of the first heating module.

[0105] The side-pull heating plate 42 can be stored inside the first furnace body 1. When stored, it can heat the glass bowl from the bottom, or it can be pulled out of the first furnace body 1 to heat other containers.

[0106] Preferably, a weighing device is provided at the bottom of the first furnace body, and a weight decoupling component is provided between the side-pull heating plate and the first furnace body. The weight decoupling component supports the side-pull heating plate after it is pulled out, and it can be used for heating scenarios such as boiling water after being pulled out. For example, an elastic support foot is provided at the bottom of the side-pull heating plate. When the side-pull heating plate is retracted, the elastic support foot retracts and is stored in the first furnace body together with the side-pull heating plate. After the side-pull heating plate is pulled out, the elastic support foot supports the weight of the side-pull heating plate. By supporting the weight of the side-pull heating plate with the elastic support foot, the removal or placement of containers or the addition or removal of water or food on the side-pull heating plate will not affect the weighing of the first furnace body, ensuring the accurate quantitative measurement of the food being grilled in the barbecue oven.

Any equivalent structural or procedural transformations made using the description and drawings of the embodiments of the present application, or direct or indirect applications in other related technical fields, are similarly included within the scope of patent protection supported by the embodiments of the present application.
