Description

Technical Field

[0001] The present invention relates to the technical field of barbecue equipment, and particularly to an environment-friendly dual-gas desktop roasting pan. Background Art

[0002] With the improvement of people's living standards, outdoor and indoor barbecue has gradually become a popular dining method, and the desktop roasting pan is favored for its portability and flexibility. However, the existing desktop roasting pans have significant deficiencies in terms of the continuity of gas supply and the efficiency of fume purification, which limit the user experience and the improvement of environmental protection performance.

[0003] In terms of gas supply, traditional desktop roasting pans generally adopt a single gas cylinder gas supply system. When the gas runs out, users need to interrupt the barbecue process to replace the gas cylinder, which not only affects the cooking continuity but also reduces the use convenience. Especially in outdoor scenarios, the problem of frequently replacing gas cylinders is more prominent. Although there are some dual-gas designs in the prior art, their switching mechanisms are complex and it is difficult to achieve seamless switching, resulting in poor actual application effects.

[0004] In terms of fume treatment, the purification functions of existing desktop roasting pans mostly remain in the primary stage. For example, some products only configure a single-layer metal filter to intercept large particles of grease, but lack effective treatment for tiny particles, harmful gases (such as polycyclic aromatic hydrocarbons) and odors in the fume; the fume that is not fully purified is directly discharged into the environment, which not only pollutes the air but may also pose a threat to the health of users. Therefore, an environment-friendly dual-gas desktop roasting pan is provided to solve the above technical problems. Summary of the Invention

[0037] The following will describe in detail an environment-friendly dual-gas desktop roasting pan of the present invention in conjunction with the accompanying drawings.

[0038] As Figures 1-4 shown, an embodiment of an environment-friendly dual-gas desktop roasting pan of the present invention includes a support housing 1 and a roasting pan frame 2 installed on the top of the support housing 1. A barbecue net 3 is placed on the roasting pan frame 2. An ignition tube 4 for providing heat source for barbecue is installed inside the roasting pan frame 2, and an ignition device 41 is provided beside the ignition tube 4. This desktop roasting pan is a gas roasting pan. After the ignition tube 4 is filled with gas and ignited by the ignition device 41, it can provide heat source for the food placed on the barbecue net 3 to achieve barbecue. Moreover, this desktop roasting pan can be directly used on the desktop indoors or outdoors, which is not only convenient to use but also easy to carry.

[0039] In order to continuously supply gas to the ignition tube 4, a first gas pressure reducing valve 5 and a second gas pressure reducing valve 51 are installed inside the support housing 1. Both the first gas pressure reducing valve 5 and the second gas pressure reducing valve 51 are equipped with gas cylinders 52. The first gas pressure reducing valve 5 and the second gas pressure reducing valve 51 are prior arts (the model can be JYT-1.2L). Both are used to reduce and stabilize the pressure output by the gas cylinder 52, and will not be elaborated here. The support housing 1 is also equipped with a control valve 6 for controlling the on-off of gas and adjusting the gas flow. The inlet of the control valve 6 is connected to the first gas pressure reducing valve 5 through a first intake pipe 7, and the inlet of the control valve 6 is also connected to the second gas pressure reducing valve 51 through a second intake pipe 8. The outlet of the control valve 6 is connected to the ignition tube 4. When this desktop roasting pan needs to be used, the control valve 6 is opened, and the gas in the gas cylinder 52 is transported through the first intake pipe 7 or the second intake pipe 8, and then ejected after being transported to the ignition tube 4. Then, it is ignited in cooperation with the ignition device 41 to eject flames for barbecue.

[0040] In addition, a switching control mechanism 9 for controlling the selective conduction of the first intake pipe 7 and the second intake pipe 8 is provided inside the support housing 1, and a controller 11 for controlling the operation of the switching control mechanism 9 is also provided. Pressure sensors 10 for detecting the pressure inside the pipes are installed on both the first intake pipe 7 and the second intake pipe 8. There are two gas cylinders 52. When using this planar grill pan, first use the gas cylinder 52 connected to the second intake pipe 8 for gas supply (it is also possible to first use the gas cylinder 52 connected to the first intake pipe 7). Under the action of the selective conduction of the switching control mechanism 9, the first intake pipe 7 is in a blocked state; when the gas in this gas cylinder 52 is used up, it is detected by the pressure sensor 10 on the second intake pipe 8 (detecting no air pressure), and then the detected electrical signal is transmitted to the controller 11 to control the operation of the switching control mechanism 9, block the second intake pipe 8, and at the same time, make the first intake pipe 7 conduct, so as to achieve the switching of the gas supply of the gas cylinder 52. By setting two gas cylinders 52 and cooperating with the switching control mechanism 9, the empty gas cylinder 52 can be replaced while grilling, preventing the grilling from stopping after the gas is used up, and improving the user experience.

[0041] In this embodiment, an oil collection frame 12 for collecting the dripping grease is installed inside the grill pan frame 2, and both the flame spraying pipe 4 and the ignition device 41 are placed inside the oil collection frame 12; during grilling, the grease generated by the food ingredients will keep dripping down and thus be collected by the oil collection frame 12. A recycling component for storing the collected grease is provided inside the support housing 1. Multiple recycling components can be set to increase the storage capacity. When enough grease is stored, recycling treatment is carried out to prevent grease leakage, which is not easy to clean, and can ensure the cleanliness of the place when used outdoors, having an environmental protection effect.

[0042] Further, the recycling component includes a fixed frame 14 disposed within the support housing 1. A storage frame 15 for storing grease is placed within the fixed frame 14. It also includes an oil guiding funnel 13. The top end of the oil guiding funnel 13 is communicatively connected to the inside of the oil collecting frame 12, and the top end face of the oil guiding funnel 13 is flush with the inner bottom surface of the oil collecting frame 12 or lower than the inner bottom surface of the oil collecting frame 12. The bottom end of the oil guiding funnel 13 passes through the top of the fixed frame 14 to introduce the grease in the oil collecting frame 12 into the storage frame 15. Multiple oil guiding funnels 13 can be provided. After the dripping grease in the oil collecting frame 12 is collected, it is diverted through the oil guiding funnels 13 into the storage frame 15 for storage. When there is a sufficient amount of grease stored, the storage frame 15 is taken out of the fixed frame 14 for recycling. Additionally, a first pull handle 16 is installed on the outer side of the storage frame 15. By providing the first pull handle 16, it is convenient for the user to take the storage frame 15 out of the fixed frame 14 or put an empty storage frame 15 into the fixed frame 14. A filter residue net 18 is installed at the top end of the oil guiding funnel 13. The filter residue net 18 is used to filter out larger impurities in the grease to prevent the impurities from blocking the oil guiding funnel 13. A convex portion 19 is formed at the middle position of the inner bottom surface of the oil collecting frame 12. The top end of the oil guiding funnel 13 is placed beside the convex portion 19. Through the convex portion 19, the grease in the oil collecting frame 12 converges towards its periphery, enabling the grease in the oil collecting frame 12 to fully flow into the storage frame 15.

[0043] When using this tabletop baking tray, fumes will be generated. To further improve the environmental protection effect, an installation platform 20 is provided on the outer side of the support housing 1. A support base 21 is installed on the installation platform 20. Above the baking pan frame 2, there is a smoke suction hood 23 for sucking fumes. Inside the smoke suction hood 23, there is a purification component for purifying the fumes. The smoke suction hood 23 is fixedly provided with a lifting frame 22, and the lifting frame 22 is arranged on the support base 21. The fumes generated during barbecue are sucked by the smoke suction hood 23, and after being sucked, they are purified by the purification component, and finally the purified gas is discharged, preventing the harmful substances in the fumes from polluting the air and further improving the environmental protection effect of this tabletop baking tray. The specific method of purification will be described below.

[0044] As Figure 5As shown, the length direction of the first intake pipe 7 is parallel and arranged side by side with the length direction of the second intake pipe 8. The switching control mechanism 9 includes a support block 91 and a sliding chamber 92 formed inside the support block 91. A valve block 93 is horizontally slidably arranged in the sliding chamber 92, and the sliding direction of the valve block 93 is perpendicular to the length direction of the first intake pipe 7 (or the second intake pipe 8). The front and rear sides of the valve block 93 are parallel to its sliding direction, and both the front side and the rear side are provided with chute modules. The chute module includes a first chute 94 and a second chute 95 arranged along the sliding direction of the valve block 93. The first chute 94 on the front side and the first chute 94 on the rear side are mirror-symmetrically arranged based on the sliding direction of the valve block 93. Similarly, the second chute 95 on the front side and the second chute 95 on the rear side are mirror-symmetrically arranged based on the sliding direction of the valve block 93. When the valve block 93 is horizontally slid in the sliding chamber 92, it will carry the first chute 94 and the second chute 95 on the front side, as well as the first chute 94 and the second chute 95 on the rear side, to slide horizontally together. Among them, the first intake pipe 7 includes a first air duct 71 and a second air duct 72 respectively placed on the front and rear sides of the support block 91, and the second intake pipe 8 includes a third air duct 81 and a fourth air duct 82 respectively placed on the front and rear sides of the support block 91; the ends of the first air duct 71 and the second air duct 72 close to the valve block 93 both pass through the support block 91 and are respectively placed in the first chutes 94 on the front and rear sides, and the ends of the third air duct 81 and the fourth air duct 82 close to the valve block 93 both pass through the support block 91 and are respectively placed in the second chutes 95 on the front and rear sides. When the valve block 93 is horizontally slid in the sliding chamber 92, the ends of the first air duct 71 and the second air duct 72 slide respectively in the first chutes 94 on the front and rear sides. Similarly, the ends of the third air duct 81 and the fourth air duct 82 slide respectively in the second chutes 95 on the front and rear sides.

[0045] A first ventilation hole 96 for connecting the first air duct 71 and the second air duct 72 is formed in the first chute 94, and a second ventilation hole 97 for connecting the third air duct 81 and the fourth air duct 82 is formed in the second chute 95. When the second ventilation hole 97 connects the third air duct 81 and the fourth air duct 82, the valve block 93 blocks between the first air duct 71 and the second air duct 72 to block the two; when switching is required, the valve block 93 is horizontally moved. After the first ventilation hole 96 connects the first air duct 71 and the second air duct 72, the valve block 93 blocks between the third air duct 81 and the fourth air duct 82 to block the two, so as to realize the switching of the two pipelines.

[0046] In this embodiment, first sealing rings 98 are provided at the ends of the first air duct 71 located in the front-side first sliding groove 94, the second air duct 72 located in the rear-side first sliding groove 94, the third air duct 81 located in the front-side second sliding groove 95, and the fourth air duct 82 located in the rear-side second sliding groove 95. Second sealing rings 99 for cooperating with the first sealing rings 98 are provided at both ends of the first vent hole 96 and both ends of the second vent hole 97. Under the cooperation of the first sealing rings 98 and the second sealing rings 99, the sealing performance when the second vent hole 97 connects the third air duct 81 and the fourth air duct 82 is improved, and the sealing performance after the first vent hole 96 connects the first air duct 71 and the second air duct 72 is improved, preventing air leakage. To control the lateral sliding of the valve block 93 in the sliding chamber 92, an electric push rod 910 with a length direction parallel to the sliding direction of the valve block 93 is installed on the top of the support block 91, and a connecting block 911 for fixedly connecting with the end of the telescopic rod of the electric push rod 910 is provided on the top of the valve block 93. By controlling the operation of the electric push rod 910 through the controller 11, when the telescopic rod of the electric push rod 910 expands and contracts, the valve block 93 can be controlled to slide laterally in the sliding chamber 92.

[0047] As Figures 6-7 shown, the lifting frame 22 is arranged to move up and down on the support base 21. An accommodation chamber 211 for accommodating the lifting frame 22 is provided inside the support base 21, and a clamping mechanism 24 for clamping and fixing the lifting frame 22 is provided at the bottom of the accommodation chamber 211. By arranging the lifting frame 22 to move up and down, the smoking hood 23 can also move up and down; when the desktop roasting pan is not in use, manually press the smoking hood 23 until the top of the roasting pan frame 2 is covered. At the same time, the clamping mechanism 24 clamps and fixes the lifting frame 22, preventing the smoking hood 23 from automatically resetting upward. Covering the top of the roasting pan frame 2 with the smoking hood 23 can not only prevent dust from adhering to its interior but also prevent foreign objects from entering, avoiding large-area cleaning and excessive consumption of water resources during use.

[0048] Furthermore, a plurality of vertically arranged first guide rods 212 are provided in the accommodation chamber 211. A slider 221 slidably connected to the first guide rods 212 is formed at the bottom end of the lifting frame 22, and a first spring 213 for applying an upward thrust to the slider 221 is wound around the first guide rods 212 between the slider 221 and the inner bottom of the accommodation chamber 211. During the downward movement of the lifting frame 22, the first spring 213 is compressed. When the clamping mechanism 24 clamps and fixes the lifting frame 22, the first spring 213 is always in a compressed state. When the clamping mechanism 24 is unlocked, under the action of the compressed first spring 213, the lifting frame 22 is pushed to reset upward.

[0049] In this embodiment, the clamping mechanism 24 includes a pair of mirror-arranged locking components and an unlocking component for synchronously unlocking the pair of locking components. By providing a pair of locking components, the lifting frame 22 can be more stably locked and fixed when it is locked. Additionally, multiple locking components can also be provided to further improve the locking and fixing effect. Among them, the locking component includes a fixed seat 241 provided at the inner bottom of the accommodating chamber 211. The fixed seat 241 rotatably has a rotating member 242 with a vertically arranged axis of rotation. The top of the rotating member 242 is formed with a slot 243 coaxially arranged with its axis of rotation. Inside the slot 243, a plurality of clamping portions are arranged in an array along the vertical direction. The locking component also includes a vertically arranged insertion rod 248 provided at the bottom of the lifting frame 22. The insertion rod 248 is coaxially arranged with the slot 243. When the lifting frame 22 moves downward to the bottommost position, the insertion rod 248 is inserted into the slot 243. A plurality of grooves 249 are formed on the side of the insertion rod 248 in an array along the vertical direction and are used for clamping with the clamping portions. After the insertion rod 248 is inserted into the slot 243, the clamping portions are snapped into the grooves 249 to clamp and fix the insertion rod 248. Additionally, a relief recess 2410 is formed on the side of the insertion rod 248. The relief recess 2410 is used to disengage the rotated clamping portion from the groove 249 to unlock the insertion rod 248. When the rotating member 242 is controlled to rotate, a plurality of clamping portions rotate together around the vertical axis. When the clamping portion rotates to align with the relief recess 2410, the clamping portion disengages from the groove 249. The relief recess 2410 is vertically and flatly arranged. Under the action of compressing the first spring 213, the lifting frame 22 is pushed upward to reset, and the insertion rod 248 is taken out of the slot 243, completing the unlocking.

[0050] In this embodiment, the clamping portion includes a buffer groove 244 formed in the rotating member 242. Inside the buffer groove 244, a sliding portion 246 that can slide horizontally in a direction close to or away from the slot 243 is provided. The sliding portion 246 is provided with a clamping block 245 whose one end extends into the slot 243. The end of the clamping block 245 placed in the slot 243 is formed with an inclined edge. The inclined edge is provided at the upper edge of the end and is used to contact the insertion rod 248. A second spring 247 for applying a thrust force to the sliding portion 246 in the direction towards the slot 243 is provided inside the buffer groove 244. During the process of the insertion rod 248 moving downward to insert into the slot 243, the side of the insertion rod 248 contacts the inclined edge. Under the cooperation with the inclined edge, the clamping block 245 is pushed to move in a direction away from the slot 243, and the second spring 247 is compressed. When the insertion rod 248 moves downward until the groove 249 aligns with the clamping block 245, under the action of compressing the second spring 247, the clamping block 245 is pushed to move in the direction towards the slot 243, so that the clamping block 245 is snapped into the groove 249 to clamp the insertion rod 248. Additionally, by providing a plurality of slots 243 and a plurality of clamping portions, the clamping portions are respectively snapped into different slots 243 to improve the clamping and fixing effect and prevent automatic unlocking.

[0051] The unlocking component includes a guide block 2411 mounted on the support base 21. A sliding frame 2412 is mounted on the guide block 2411 for transverse sliding movement. A coaxial gear 2414 is mounted on the outer side of the rotating member 242. The sliding frame 2412 is provided with a rack 2413 for meshing with the gear 2414. Applying force to the sliding frame 2412 causes it to slide transversely on the guide block 2411, driving the rack 2413 with it. In conjunction with the gear 2414, the rotating member 242 is controlled to rotate on the fixed base 241. Once the locking block 245 aligns with the recessed portion 2410 and disengages the slot 249, the insertion rod 248 is unlocked. Furthermore, each locking component is provided with a gear 2414. The number of racks 2413 on the sliding frame 2412 matches the number of locking components. When the force applied to the sliding frame 2412 ceases, to achieve automatic return of the sliding frame 2412, a second guide rod 2415 is provided on the inner sidewall of the accommodating chamber 211, its length aligned with the sliding direction of the sliding frame 2412. The second guide rod 2415 is slidably arranged with the sliding frame 2412. A limit member 2416 is provided at the end of the second guide rod 2415 away from the inner sidewall of the accommodating chamber 211. A third spring 2417 is wound around the second guide rod 2415 and positioned between the limit member 2416 and the sliding frame 2412 to apply a lateral thrust to the sliding frame 2412. When force is applied to the sliding frame 2412 to cause it to slide laterally on the guide block 2411, the third spring 2417 is compressed. When the force applied to the sliding frame 2412 ceases, the compressed third spring 2417 pushes the sliding frame 2412 to return to its original position.

[0052] like Figures 8-9 As shown, the purification component includes a mounting plate 26 mounted within the smoke hood 23 and a smoke extraction module 31. The smoke extraction module 31 is composed of multiple fans and is used to extract cooking fumes during barbecue. A first mounting slot 27 is formed on the bottom surface of the mounting plate 26, and a second mounting slot 28 is formed within the first mounting slot 27. The first and second mounting slots 27 and 28 are arranged in a stepped manner. The second mounting slot 28 houses a first filter 29, which is positioned directly below the smoke extraction module 31 and is used to filter grease particles from the cooking fumes. The first mounting slot 27 houses a second filter 30, which is positioned directly below the smoke extraction module 31 and functions similarly to the first filter 29. When smoke is extracted by the smoke extraction module 31, the smoke passes through the second filter 30 and the first filter 29, respectively, intercepting larger liquid oil droplets and oil mist from the smoke, completing the first purification process.

[0053] A first magnet 291 is provided both inside the second installation groove 28 and at the edge of the first filter net 29, and a second magnet 301 is provided both inside the first installation groove 27 and at the edge of the second filter net 30. When the first filter net 29 is inserted into the second installation groove 28, the first magnets 291 attract each other. When the second filter net 30 is inserted into the first installation groove 27, the second magnets 301 attract each other. The first filter net 29 and the second filter net 30 are installed directly below the smoking module 31 by magnetic attraction, so as to facilitate the removal of both for cleaning or replacement.

[0054] In addition, a smoke guide frame 25 is provided at the top of the smoking hood 23 and is connected to the smoking hood 23. The top frame opening size of the smoke guide frame 25 is smaller than the top size of the smoking hood 23. A boss 32 is formed on the inner side of the top of the smoke guide frame 25, and a condensation plate 33 for condensing and liquefying cooking fumes is placed on the boss 32. A collection frame 34 for collecting the liquefied liquid (grease mixture) is installed on the inner side of the top of the smoking hood 23 directly below the condensation plate 33. When the smoking module 31 sucks the cooking fumes, the cooking fumes pass through the second filter net 30, the first filter net 29, the smoke guide frame 25, and the condensation plate 33 in sequence from bottom to top. First, the cooking fumes are subjected to the first purification process by the second filter net 30 and the first filter net 29, and then the cooking fumes are condensed and liquefied by the condensation plate 33. The liquefied liquid automatically drips into the collection frame 34, realizing the second purification process of the cooking fumes. The collection frame 34 can be taken out from the inner side of the top of the smoking hood 23. A second pull handle 35 is installed on the outer side of the collection frame 34. When enough grease mixture is collected in the collection frame 34, the second pull handle 35 is provided to pull the collection frame 34 out from the inner side of the top of the smoking hood 23, so as to recycle the grease mixture.

[0055] In this embodiment, the purification component further includes a support kit 36 sleeved on the outer side of the top of the smoke guide frame 25. The support kit 36 is provided with a filter cartridge 37 connected to the smoke guide frame 25. An activated carbon layer 38 for adsorbing harmful substances is filled inside the filter cartridge 37. After the cooking fumes pass through the condensation plate 33, they then pass through the activated carbon layer 38, thereby removing the harmful substances in the cooking fumes and realizing the third purification process of the cooking fumes. During the process of sucking the cooking fumes, the filtration process, the condensation process, and the adsorption process are carried out in sequence, and after three purification processes, the cooking fumes are discharged, realizing the full purification of the cooking fumes, preventing air pollution, and further improving the environmental protection effect. In addition, the support kit 36 can be removed from the top of the smoke guide frame 25, and then the condensation plate 33 can be removed from the boss 32 inside the smoke guide frame 25, which is convenient for cleaning or replacing the condensation plate 33.

[0056] In summary, it can be seen that the present invention has the excellent characteristics described above, enabling it to enhance the efficiency that has never been achieved in the prior art during use and having practicality, thus becoming a product with extremely high practical value.
