Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of barbecue equipment, and particularly relates to an environmentally-friendly double-gas-source tabletop roasting pot. BACKGROUND

[0002] With the improvement of people's living standards, outdoor and indoor barbecue gradually becomes a popular dining method, and the tabletop roasting pot is favored due to its portability and flexibility. However, the existing tabletop roasting pot has significant deficiencies in gas supply continuity and oil fume purification efficiency, which limits the improvement of user experience and environmental performance.

[0003] In terms of gas supply, the traditional tabletop roasting pot generally adopts a single gas tank gas supply system. When the gas is consumed, the user needs to interrupt the barbecue process to replace the gas tank, which not only affects the cooking continuity, but also reduces the use convenience, especially the problem of frequent replacement of gas tanks in outdoor scenarios. Although there are some double-gas-source designs in the prior art, the switching mechanism is complex and it is difficult to achieve seamless switching, resulting in poor actual application effect.

[0004] In terms of oil fume treatment, the purification function of the existing tabletop roasting pot is mostly at the primary stage. For example, some products only configure a single layer of metal filter screen to intercept large particle grease, but lack effective treatment of small particles, harmful gases (such as polycyclic aromatic hydrocarbons) and odors in the oil fume. The oil fume without sufficient purification is directly discharged into the environment, which not only pollutes the air, but also may pose a threat to the health of users. Therefore, the present application provides an environmentally-friendly double-gas-source tabletop roasting pot to solve the above technical problems. SUMMARY

DETAILED DESCRIPTION

[0037] The following is a detailed description of an environmentally friendly dual-gas-source desktop baking pan according to the present invention, with reference to the accompanying drawings.

[0038] like Figures 1-4 As shown, an embodiment of the environmentally friendly dual-gas-source desktop grill pan of the present invention includes a supporting shell 1 and a grill pan frame 2 installed on the top of the supporting shell 1. A grilling rack 3 is placed on the grill pan frame 2. A flame pipe 4 for providing a heat source for grilling is installed inside the grill pan frame 2, and an ignition device 41 is provided next to the flame pipe 4. This desktop grill pan is a gas-fired grill pan. After gas is introduced into the flame pipe 4 and ignited by the ignition device 41, a heat source can be provided for the food placed on the grilling rack 3 to achieve grilling. Furthermore, this desktop grill pan can be placed directly on an indoor or outdoor table for use, which is not only convenient to use but also easy to carry.

[0039] To continuously supply gas to the flame 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 existing technologies (model JYT-1.2L), and both are used to reduce and stabilize the pressure output from the gas cylinder 52, which will not be described in detail here. The support housing 1 is also equipped with a control valve 6 for controlling the gas supply and regulating the gas flow. The inlet of the control valve 6 is connected to the first gas pressure reducing valve 5 through a first inlet pipe 7, and the inlet of the control valve 6 is also connected to the second gas pressure reducing valve 51 through a second inlet pipe 8. The outlet of the control valve 6 is connected to the flame tube 4. When this desktop grill pan is needed, the control valve 6 is opened, and the gas in the gas cylinder 52 is transported through the first inlet pipe 7 or the second inlet pipe 8 to the flame tube 4 for emission. Then, it is ignited by the ignition device 41 to produce flames for grilling.

[0040] In addition, the support shell 1 is internally provided with a switching control mechanism 9 for controlling the selective conduction of the first air inlet pipe 7 and the second air inlet pipe 8, and a controller 11 for controlling the operation of the switching control mechanism 9. The first air inlet pipe 7 and the second air inlet pipe 8 are both provided with a pressure sensor 10 for detecting the pressure in the pipe. Two gas cylinders 52 are provided. When the present grilling pot is used, the gas cylinder 52 in communication with the second air inlet pipe 8 is used to supply gas (the gas cylinder 52 in communication with the first air inlet pipe 7 can also be used). Under the action of the switching control mechanism 9, the first air inlet pipe 7 is in a blocked state. When the gas in the gas cylinder 52 is used up, the pressure sensor 10 on the second air inlet pipe 8 detects that there is no gas pressure, and then transmits the detected electrical signal to the controller 11 to control the operation of the switching control mechanism 9, which blocks the second air inlet pipe 8 and simultaneously causes the first air inlet pipe 7 to be conducted, thereby realizing the switching of the gas cylinder 52 for gas supply. By providing 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 when the gas is used up, and improving the user's experience.

[0041] In the present embodiment, the grilling pot frame 2 is internally provided with an oil collecting frame 12 for collecting the dripped oil, and the flame jet pipe 4 and the ignition device 41 are both arranged in the oil collecting frame 12. When grilling, the oil produced by the food material will continuously drip down and be collected by the oil collecting frame 12. The support shell 1 is internally provided with a recovery component for storing the collected oil. The recovery component can be provided in multiple numbers to increase the storage capacity. When a sufficient amount of oil is stored, recovery treatment is performed to prevent oil leakage, which is inconvenient to clean, and to ensure the cleanliness of the place when used outdoors, thereby having an environmental protection effect.

[0042] Further, the recycling part comprises a fixed frame 14 arranged in the supporting shell 1, a storage frame 15 for storing oil is arranged in the fixed frame 14, and an oil guide funnel 13 is arranged, the top end of the oil guide funnel 13 is communicated with the inside of the oil collecting frame 12, and the top end surface of the oil guide funnel 13 is flush with or lower than the inside bottom surface of the oil collecting frame 12, and the bottom end of the oil guide funnel 13 penetrates the top of the fixed frame 14 to guide the oil in the oil collecting frame 12 into the storage frame 15. The oil guide funnel 13 can be arranged in plurality, after the oil dripping in the oil collecting frame 12 is collected, it is guided to the storage frame 15 through the oil guide funnel 13 for storage, when a sufficient amount of oil is stored, the storage frame 15 is taken out from the fixed frame 14 for recycling. In addition, a first pull handle 16 is arranged outside the storage frame 15, the first pull handle 16 is arranged to facilitate the user to take out the storage frame 15 from the fixed frame 14, or to put the empty storage frame 15 into the fixed frame 14. A residue filter net 18 is arranged at the top end of the oil guide funnel 13, the residue filter net 18 is used to filter out the larger impurities in the oil, to prevent the impurities from blocking the oil guide funnel 13. A protruding portion 19 is formed in the middle of the inside bottom surface of the oil collecting frame 12, the top end of the oil guide funnel 13 is arranged beside the protruding portion 19, and the oil in the oil collecting frame 12 is gathered to the side of the protruding portion 19, so that the oil in the oil collecting frame 12 can fully flow into the storage frame 15.
