DETAILED DESCRIPTION

[0021] The application will be further described below in conjunction with specific embodiments and drawings.

Based on the embodiments below, all other embodiments obtained by those skilled in the art without creative effort are within the scope of the present application.

[0022] It should be understood that the controller and control circuit involved in the embodiments are the control technology or units commonly used by those skilled in the art, and the control circuit of the controller can be implemented by those skilled in the art using existing technology.

[0023] The disclosure of the embodiments provides many different implementations or examples to implement different aspects of the application. In order to simplify the disclosure of the application, the components and settings of specific examples are described in the embodiments. Of course, they are only examples and the purpose is not to limit the application. In addition, reference numerals and / or reference letters can be repeated in different examples in the embodiments. Such repetition is for the purpose of simplification and clarity, and does not in itself indicate a relationship between the various implementations and / or settings being discussed. In addition, if examples of various specific processes and materials are provided in the embodiments, those skilled in the art can realize the application of other processes and / or the use of other materials.

[0024] In conjunction with Figures 1-5 As shown, the first embodiment of the barbecue oven comprises a first oven body 1 and a second oven body 2, which are connected by a rotating shaft 3 into an opening and closing structure. 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 flat-open mode position positioned by the rotating shaft 3; the overall structure of the embodiment is the openable and closable furnace body state composed of the first furnace body 1, the second furnace body 2 and the rotating shaft 3, and in the specific structural composition, the first furnace body 1 includes a first shell 101, the first shell 101 is provided with a first structural frame 102, the first structural frame 102 is a structural member lined in the first shell 101, the first structural frame 102 is provided with a first heating assembly 103, the first heating assembly 103 has a first heating space 104 in the middle part, the first heating assembly 103 is a structural assembly including an infrared heating tube, a reflector, a heat dissipation assembly and a mounting structure, and specifically includes a mounting support 105, the mounting support 105 serves as the mounting basis of other internal components, the first infrared heating tube 106 and the second infrared heating tube 107 are respectively arranged on the mounting support 105 at positions opposite to both sides of the first heating space 104, the first infrared heating tube 106 and the second infrared heating tube 107 heat through heat radiation, heat radiation is a form of heat transfer, when electric current passes through the resistance wire inside the heating tube, the resistance effect converts electric energy into heat energy, so that the surface temperature of the heating tube rapidly rises, the heating tube radiates energy in the form of electromagnetic waves, so it is called heat radiation, and the main wave band is infrared, which can act on food to form a state of barbecue heating.

[0025] The back sides of the first infrared heating tube 106 and the second infrared heating tube 107 are respectively provided with reflectors 108, the reflectors 108 reflect the infrared rays emitted by the first infrared heating tube 106 and the second infrared heating tube 107 to the direction of the first heating space 104, so as to heat the food or the vessel loaded with food placed in the first heating space 104 through heat radiation. The emitted light of the reflector 108 has the characteristic of diverging within a certain range to the emission area.

[0026] In the embodiment, the first infrared heating tube 106 and the second infrared heating tube 107 are arranged on opposite sides of the first heating space 104, so that the heat source area is located on both sides of the food area, the oil droplets and the high-temperature heat source are separated, and the generation of oil fume is effectively avoided. Meanwhile, in order to isolate the food area and the first infrared heating tube 106 and the second infrared heating tube 107, transparent cover plates 109 are respectively arranged on the mounting support 105 corresponding to the first infrared heating tube 106 and the second infrared heating tube 107, the first infrared heating tube 106 and the second infrared heating tube 107 are enclosed on both sides of the mounting support 105 after the transparent cover plates 109 cover the first infrared heating tube 106 and the second infrared heating tube 107.

[0027] Since the transparent cover plate 109 covers the mounting area of the first and second infrared heating tubes 106 and 107, the heat of the mounting area of the first and second infrared heating tubes 106 and 107 is difficult to dissipate quickly during operation, causing the temperature of the corresponding area outside the machine to be relatively high. In order to avoid the heat of the mounting area of the first and second infrared heating tubes 106 and 107 from gathering, a heat dissipation structure can be further arranged on the side of the first and second infrared heating tubes 106 and 107 to avoid the local shell temperature from being too high.

[0028] In the embodiment, the first heating space 104 can be used to hold food materials. In order to further facilitate the placement and collection of food materials, a first glass pot 110 is arranged in the middle of the first structural frame 102. Based on the heating direction setting in the embodiment, the position corresponding to the first and second infrared heating tubes 106 and 107 on the first glass pot 110 is a slope, and the heat radiation direction of the first and second infrared heating tubes 106 and 107 is inclined towards the corresponding slope direction.

[0029] Preferably, in order to facilitate the taking and placing of the first glass pot 110, side ears 111 are arranged on both sides of the first glass pot 110. In order to make the side ears 111 of the first glass pot 110 not protrude from the overall surface when placed in the first structural frame 102, avoiding affecting the closure of the first and second furnace bodies 1 and 2, recesses 112 are arranged on the first structural frame 102 corresponding to the side ears 111 to accommodate the side ears 111.

[0030] 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 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 through the rotating shaft 3.

[0031] The difference between the first furnace body 1 and the second furnace body 2 is that: I. In order to facilitate control and operation, the first furnace body 1 is further provided with a control panel 113, which includes control buttons, a display area, and a corresponding circuit board. The second furnace body 2 is movable, so it generally does not have a control panel.

[0032] II. Since the second furnace body 2 is a downwardly open structure, its second glass pot 207 needs to be clamped in the second furnace body 2.

[0033] 3. A transparent window 208 can be set on the upper surface of the second furnace body 2 for observing the food inside when it is closed.

[0034] 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.

[0035] like Figures 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 a closed mode, a half-open mode, and a flat open mode corresponding to the closed mode position, the half-open mode position, and the flat open mode position that can be positioned by the rotating shaft.

[0036] The aforementioned closed mode, half-open mode, and open mode are set to correspond to 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.

[0037] Since the structure and function settings in the semi-open mode are significantly different from those of existing barbecue grills, we will first explain the structure and function implementation in the semi-open mode.

[0038] like Figure 6 As 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.

[0039] Preferably, since the first infrared heating tube 106 and the second infrared heating tube 107 in the first heating module heat the lower and side of the first glass pot in the half-open mode, and the third infrared heating tube 205 heats the upper of the first glass pot 110, at this time, there are two heat sources below the food and only one heat source above the food, which is easy to cause the heating degree of the upper and lower of the food to be inconsistent, therefore, in the half-open mode, the working power of the third infrared heating tube 205 is greater than the working power of the first infrared heating tube 106 or the second infrared heating tube 107. The specific working mode can be calculated according to the heating angle and the heating distance, so as to achieve the requirement that the heating of the upper and lower tends to be consistent in the half-open mode.

[0040] As shown in Figure 7 , 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 an inner space, and the first heating module and the second heating module jointly heat the inner space to heat the food in the inner space in all directions.

[0041] Preferably, since the second furnace body 2 upper surface can be provided with a transparent window 208, the first infrared heating tube 106 and the second infrared heating tube 107 will emit a large amount of light from the transparent window 208, causing the upper temperature of the barbecue oven to be relatively high, so 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, and the third infrared heating tube 205 and the fourth infrared heating tube 206 are used as the main heating source, and the first infrared heating tube 106 and the second infrared heating tube 107 are used as the auxiliary heating source.

[0042] As shown in Figure 8 , when the first furnace body 1 and the second furnace body 2 are in the flat-open mode position, 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.

[0043] Since the above scheme is adopted, the multi-mode barbecue oven of the embodiment of the present application can automatically determine whether the first furnace body and the second furnace body are in the closed mode position, the flat-open mode position or the half-open mode position according to the relative angle of the first furnace body and the second furnace body, so as to 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 the barbecue oven to heat the food from both sides in the half-open state, improving the food heating efficiency and reducing manual operation.

[0044] The closing mode position, the half-open mode position and the flat-open mode position are represented by the rotation shaft and have two functional meanings. Firstly, when the first furnace body 1 and the second furnace body 2 are in the closing mode position, the flat-open mode position and the half-open mode position at a preset angle, the first furnace body 1 and the second furnace body 2 can be locked by the rotation shaft 3, so that the first furnace body 1 and the second furnace body 2 are kept in the corresponding mode position. Secondly, the relative angle of the first furnace body 1 and the second furnace body 2 can be fed back by the rotation shaft, so that whether the first furnace body 1 and the second furnace body 2 are in the closing mode position, the half-open mode position and the flat-open mode position can be determined, so as to select the heating mode and perform corresponding automatic control. In the embodiment, the rotation shaft has the above two functional meanings, that is, the rotation shaft 3 can lock the first furnace body 1 and the second furnace body 2 in the closing mode position, the half-open mode position and the flat-open mode position, and can also monitor and feed back the relative angle of the first furnace body 1 and the second furnace body 2, that is, when the first furnace body 1 and the second furnace body 2 reach the corresponding closing mode position, half-open mode position and flat-open mode position, a corresponding feedback signal is generated to execute the corresponding heating mode.

[0045] In order to realize the above structure and function, the embodiment of the present application also provides a rotation shaft which can be manually locked and unlocked and can feed back the angle. In the overall structure of the rotation shaft, the rotation shaft is composed of a first shaft segment, a second shaft segment and a third shaft segment. The first shaft segment, the second shaft segment and the third shaft segment are coaxially connected. The first shaft segment is connected to the second furnace body, that is, the upper furnace body. The second shaft segment and the third shaft segment are connected to the first furnace body, that is, the lower furnace body. In the opening and closing process of the first furnace body, the first shaft segment rotates coaxially relative to the second shaft segment and the third shaft segment. The opening and closing state of the first furnace body is positioned by the rotation shaft. The positioning at least locks the angle position of the first furnace body in the half-open position. As far as possible, the closing state and the flat-open state can also be locked in the closing position and the flat-open position. Meanwhile, the opening and closing angle of the first furnace body can be fed back, so as to execute the corresponding working state of the barbecue oven. In order to realize the above functional requirements, a locker and a clamping sheet are respectively arranged in the first shaft segment and the second shaft segment. The locker has a locking column protruding from the end face of the locker. The clamping sheet is provided with a locking hole matched with the locking column. In order to control the locking of the locker and the clamping sheet, the locker is connected with a locker control assembly. The locker control assembly drives the locker to combine with the clamping sheet for locking or to separate from the clamping sheet for unlocking. In addition, in order to detect the rotation angle of the first shaft segment, an angle sensor can be arranged between the first shaft segment and the second shaft segment, or between the first shaft segment and the third shaft segment. The specific arrangement position can be determined according to the layout of the installation space.

[0046] Based on the overall structure of the above rotation shaft, the specific components and structure settings are described through three embodiments.

[0047] In the second embodiment, as shown in Figures 9-11 The rotating shaft 3 of the second embodiment comprises 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 and the third shaft segment 33 are respectively connected to the first furnace body 1. The first shaft segment 31 is coaxial with the second shaft segment 32 and the third shaft segment 33 and can rotate relative to them.

[0048] The first shaft segment 31 comprises a first shaft sleeve 311, a first inner shaft 312 and a lock 313. The first shaft sleeve 311 is provided with a first clamping strip 314. The first inner shaft 312 is provided with a first clamping groove 315. The lock 313 is provided with a second clamping groove 316. The first shaft sleeve 311, the first inner shaft 312 and the lock 313 are synchronously rotatable through the cooperation of the first clamping strip 314, the first clamping groove 315 and the second clamping groove 316. The lock 313 can slide in the first shaft sleeve 311 along the first clamping strip 314.

[0049] The lock 313 is provided with a locking column 317 on the outside. A locking spring 318 is arranged between the first inner shaft 312 and the lock 313. The lock 313 is limited in the first shaft sleeve 311 by a lock retainer ring 319. The lock retainer ring 319 prevents the lock 313 from sliding out of the first shaft sleeve 311 when it slides horizontally.

[0050] The second shaft segment 32 comprises a second shaft sleeve 321. The second shaft sleeve 321 is provided with a clamping piece 322 near one end of the lock 313. The clamping piece 322 is provided with a locking hole 323.

[0051] When the locking column 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 position of the locking column 317 and the locking hole 323 is set to lock the position of 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 column 317 is inserted into the locking hole 323 at the corresponding angle of the first shaft segment 31 and the second shaft segment 32. When locking in the flat-open state of the first furnace body and the second furnace body, it is necessary to ensure that the locking column 317 is inserted into the locking hole 323 at the corresponding angle 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 column 317 is inserted into the locking hole 323 at the corresponding angle 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 clamping piece 322, and at least one locking column 317 can be provided on the lock 313.

[0052] The lock 313 is connected with a lock control assembly 34, which comprises 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 arranged at two ends of the rotating wheel 341. An inner spiral 344 is arranged on the rotating wheel 341 at the rotating inner sleeve. An outer spiral 345 is arranged on the rotating inner sleeve 342 and matched with the inner spiral 344. The inner spiral 344 and the outer spiral 345 are screw matched. When the rotating inner sleeve 342 rotates, the matching depth of the outer spiral 345 in the inner spiral 344 can be adjusted, and then the relative distance between the rotating inner sleeve 342 and the rotating wheel 341 is adjusted.

[0053] The rotating wheel 341 moves horizontally by the matching of the outer spiral 345 and the inner spiral 344 when the rotating inner sleeve 342 rotates. The transmission unlocking rod 343 passes through the clamping sheet 322 and is connected to the lock 313.

[0054] The rotating inner sleeve 342 is connected with a rotating handle 35. The rotating handle 35 is a component for executing locking and unlocking, that is, an operating component. The rotating handle 35 can drive the rotating inner sleeve 342 to rotate, and then drive the lock 313 to move horizontally.

[0055] The rotating wheel 341 is provided with a baffle 346. The middle part of the clamping sheet 322 is provided with a through hole 324 for the transmission unlocking rod 343 to pass through and connect the lock 313. When unlocking, the rotating handle 35 is rotated, and the rotating inner sleeve 342 rotates. At this time, the outer spiral 345 on the rotating inner sleeve 342 acts on the inner spiral 344, and then pushes the rotating wheel 341 to move in the direction of the first inner shaft. At this time, the movement of the rotating wheel 341 applies a pushing force to the lock 313 through the transmission unlocking rod 343, so that the locking column 317 on the lock 313 is separated from the locking hole 323 on the clamping sheet 322. At this time, the locking structure of the first shaft segment 31 and the second shaft segment 32 is separated. At this time, the second furnace body 2 is operated to adjust the opening angle of the second furnace body 2 and the first furnace body 1. According to the needs, the barbecue oven is adjusted to a closed state, a half-open state or a flat-open state.

[0056] In the above structure, the rotating handle 35 is controlled by the rotation angle to unlock and lock. In fact, the unlocking and locking can also be realized by the key pressing mode. However, the key pressing needs to apply a horizontal pushing force to the barbecue oven, which is easy to cause the movement of the barbecue oven. Therefore, the structure of the rotating handle 35 is preferred.

[0057] When the lock is released, the rotating handle 35 is rotated, and the rotating inner sleeve 342 is synchronously rotated. At this time, the outer spiral 345 of the rotating inner sleeve 342 acts on the inner spiral 344, and the rotating wheel 341 is pulled to move towards the rotating inner sleeve 342. At this time, the rotating wheel 341 releases the pushing force applied to the locker 313 through the transmission unlocking rod 343, and the locker moves towards the clamping sheet 322 under the elastic force of the locking spring 318. Then, the locking column 317 on the locker 313 enters the locking hole 323 on the clamping sheet 322 under the elastic force, and the locking structure of the first shaft section 1 and the second section 2 is locked and cannot rotate relative to each other. Since the first shaft section 1 is fixed on the second furnace body, and the second shaft section 32 is fixed on the first furnace body, at this time, the opening and closing action between the second furnace body and the first furnace body is stopped and maintained.

[0058] In the embodiment, the third shaft section 33 includes a third shaft sleeve 331, which is connected to the first furnace body 1 when the furnace body is installed. The third shaft sleeve 331 is provided with a first mounting sheet 332, and the corresponding end surface of the first shaft sleeve 31 is provided with a second mounting sheet 333. The first mounting sheet 332 and the second mounting sheet 333 are provided with a damping sheet 334. The damping sheet 334 causes the rotation of the second furnace body 2 to be affected by a friction force, avoiding its rapid falling under the action of gravity, so that the second furnace body 2 can slowly fall when no one operates, avoiding the impact between the furnace bodies and improving the user experience.

[0059] In the embodiment, the first mounting sheet 332 is provided with a Hall sensing sheet 335, which is a circuit carrier of 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 sensing sheet 335, so as to execute the corresponding working mode.

[0060] The third embodiment provides an electric locking and unlocking rotating shaft.

[0061] As shown in Figure 12 and Figure 13 Similar to the second embodiment, the rotating shaft 3 of the third embodiment includes a first shaft section 31, a second shaft section 32, and a third shaft section 33. In the embodiment, the first shaft section 31 is connected to the second furnace body 2, and the second shaft section 32 is connected to the first furnace body 1. The first shaft section 31 and the second shaft section 32 are coaxial and can rotate relative to each other, and the third shaft section 33 is connected to the first furnace body 1.

[0062] The first shaft section 31 comprises a first shaft sleeve 311 and a first inner shaft 312 and a lock 313, the first inner shaft 312 is provided with an electromagnet 3110, the electromagnet 3110 comprises an electromagnet base 3111 and a movable mandrel 3112 in the electromagnet base, the movable mandrel 3112 can move horizontally relative to the electromagnet base 3111 after being electrified, adjusting the current direction can adjust the movement direction of the movable mandrel 3112, the movable mandrel 3112 is connected and drives the lock 313, and then drives the lock 313 to move horizontally.

[0063] In the third embodiment, the locking column structure on the lock 313 and the clamping sheet structure on the second shaft section 32 and the structural relationship when locking and unlocking are generated by cooperation are the same as in the second embodiment, which will not be repeated here.

[0064] The fourth embodiment provides a rotating shaft that combines electric locking and unlocking with manual unlocking, so that the barbecue oven can be unlocked and opened in the case of accidental power failure.

[0065] As shown in Figures 14-15 In the fourth embodiment, the first shaft section 31 comprises a first shaft sleeve 311, the first shaft sleeve 311 is provided with a motor fixing sleeve 3113, the motor fixing sleeve 3113 is provided with a planetary reduction motor 3114, the output end of the planetary reduction motor 3114 is connected with a rotating wheel 3115, the outer side wall of the rotating wheel 3115 is provided with an external thread 3116, the rotating wheel 3115 is sleeved with a rotating sleeve 3117, the inner side wall of the rotating sleeve 3117 is provided with an internal thread 3118, the external thread 3116 and the internal thread 3118 cooperate to convert the clockwise and counterclockwise rotation of the rotating wheel 3115 into the linear reciprocating motion of the rotating sleeve 3117. The outer side end face of the rotating sleeve 3117 is connected with the lock 313 through a connecting column 3119. Therefore, when the rotating sleeve 3117 is driven to move linearly, the lock 313 can be pushed and pulled horizontally, and then the lock 313 is combined with and separated from the clamping sheet 322, achieving the purpose of electric locking and unlocking.

[0066] 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.

[0067] 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.

[0068] 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.

[0069] 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 17As shown, a lower accommodating space is arranged at the bottom of the first furnace body 1, one side of the lower accommodating space is provided with a side pull groove 41, and a side pull heating plate 42 is arranged in the lower accommodating space, which can be pulled out of the first heating module bottom or accommodated in the first heating module bottom.

[0070] The side pull heating plate 42 can be accommodated in the first furnace body 1, and when accommodated, the glass pot can be heated from the bottom, or the side pull heating plate 42 can be pulled out of the first furnace body 1 to heat other containers.

[0071] Preferably, a weighing device is arranged at the bottom of the first furnace body, and a weight decoupling assembly is arranged between the side pull heating plate and the first furnace body, which can carry the side pull heating plate after being pulled out and can be used in scenarios such as water heating after being pulled out. For example, elastic supporting feet are arranged at the bottom of the side pull heating plate, which are retracted and accommodated in the first furnace body together with the side pull heating plate when the side pull heating plate is accommodated, and the elastic supporting feet carry the weight of the side pull heating plate after the side pull heating plate is pulled out, so that the first furnace body is not affected by the placing or removing of containers or the adding or reducing of water or food materials on the side pull heating plate, and the precise amount of barbecue food materials in the barbecue oven is ensured.

[0072] The sixth embodiment of the present application provides a multi-mode barbecue oven with a side pull heating plate based on the first and second embodiments, which further enriches the working modes and use scenarios of the barbecue oven.

[0073] The sixth embodiment of the present application also provides a control method of the barbecue oven according to the first aspect, which comprises the following steps: S1. Obtain a working instruction, which comprises a working mode and a working parameter, the working mode comprises a closed mode, a half-open mode and a flat-open mode, and the working parameter comprises a heating gear and a heating time; S2. Adjust the first furnace body and the second furnace body to one of the working positions in the closed mode, the half-open mode and the flat-open mode according to the working instruction; S3. Start the corresponding working mode and execute the corresponding working parameter according to the working position; wherein, In the closed mode, the second heating module is controlled as the main heating source, and the first heating module is controlled as the auxiliary heating source; In the half-open mode, the first heating module and the third infrared heating tube jointly form a heating source; In the flat-open mode, the first heating module and the second heating module are controlled as the main heating sources, respectively.

[0074] Therefore, the barbecue oven control method has three control modes, namely, closed, half-open and flat-open, and the working modes are different in different open and closed states. In the flat-open state, the upper and lower groups of heating pipes work independently and do not interfere with each other, so the power of the two groups can be controlled respectively, and the power of the two heating pipes in the same group is the same. In the closed state, the power of the upper and lower groups of heating pipes has a certain proportional relationship, which can be adjusted according to the cooking needs, and the overall power of the four heating pipes is adjusted in proportion. In addition, the controller reads the data of the temperature sensor installed in the barbecue oven to obtain the temperature in the barbecue oven. Then, through the temperature closed-loop control algorithm, the power of the heating pipe is controlled, so that the temperature in the barbecue oven is kept constant, and the constant temperature control function is realized. In the half-open state, the upper two heating pipes are not in a horizontal relationship with the actual grilling plane, so that the power of the two heating pipes needs to be distributed. Therefore, the upper two heating pipes can be controlled independently, and the power of the two heating pipes can be controlled independently according to the required power. The power of the lower two heating pipes is the same, and the overall power is adjusted in proportion. The barbecue oven has multiple working modes, each working mode corresponds to different control modes, and the power of the heating pipes in different working modes is controlled through software by using independent control of each heating pipe.

[0075] The seventh embodiment of the present application also provides a multi-mode barbecue oven control system, which comprises: A barbecue oven open and closed state detection module is used to obtain the open and closed positions of the first heating module and the second heating module of the barbecue oven, and the open and closed positions include a closed mode position, a half-open mode position and a flat-open mode position. A controller is used to store the corresponding parameters of the working modes, obtain the open and closed positions detected by the barbecue oven open and closed state detection module, and execute the corresponding working modes according to the open and closed state signals. The working modes include a closed mode, a flat-open mode and a half-open mode. The first heating module and the second heating module each comprise a plurality of infrared heating pipes, and are connected with the controller to execute heating according to the parameters of the working modes in the controller. An adjustment module is connected with the controller and sends a parameter adjustment signal to the controller. An indication module is connected with the controller and obtains and displays the working modes.

[0076] A communication module is connected with the controller and is used to receive control instructions.

[0077] The connection is a circuit connection or a signal interaction connection. The control instruction received by the communication module can be a single instruction, such as power on / off and firepower adjustment, or a set of instructions, such as a series of instructions defined and obtained in the form of a recipe. For example, the communication module receives an instruction sent by the control end, and then instructs the user to adjust the barbecue oven to the corresponding open / close state through the indication module, so as to enter the corresponding working mode and load the running parameters, including the power size of the heat source, the heating time, etc.

[0078] Preferably, in the embodiment, the software end and the barbecue oven end communicate through Bluetooth. The barbecue oven end transmits the current working state information of the barbecue oven to the software end in real time, including but not limited to the open / close state, the mode, the sensor data, the control data, etc. The software end displays the known information after receiving the information from the barbecue oven end. The user can check the working state of the barbecue oven on the software end, and can also control the barbecue oven on the software end, including but not limited to setting the power of different heating tubes and setting multi-step automatic execution. The software end sends the control information of the user to the barbecue oven end in real time, and the barbecue oven end detects the rationality of the control information sent by the software end and executes it.

[0079] The above is only the preferred embodiment of the embodiment of the application, and does not limit the disclosure range of the embodiment of the application. Any equivalent structure or equivalent flow transformation based on the content of the specification and drawings of the embodiment of the application, or direct or indirect application in other related technical fields, is also included in the patent protection range supported by the embodiment of the application.
