Description

Technical Field

[0001] The utility model relates to the field of air fryers, in particular to a multifunctional air fryer. Background Art

[0002] With the improvement of people's living standards, the oil-free cooking method of air fryers is becoming more and more popular. Among the existing air fryers, most air fryers are configured with heating tubes and heat circulation fans in the cooking cavity to generate a high-speed circulating heat flow to heat the food in the cooking cavity. Although the high-speed circulating heat flow is used to heat the food in the cooking cavity, oil-free cooking can be achieved, making the cooked food healthier. However, since the circulating heat flow will take away a large amount of moisture in the food when flowing at a high speed, it is easy to cause the cooked food to taste dry or woody, which results in a poor user experience. In order to meet user needs, a type of air fryer with a water or oil replenishing function has appeared on the market. This type of air fryer is configured with a water tank or an oil tank connected to the cooking cavity on the body, which can replenish water or oil in the cooking cavity, thereby effectively improving the taste of food. However, since the water or oil replenishment of this type of air fryer is usually separate, the function is relatively single, the applicability is poor, and the user experience is not good. Utility Model Content

[0003] The present application provides a multifunctional air fryer to solve the technical problems of existing air fryers having relatively single functions, poor applicability, and poor user experience.

[0004] In order to solve the above technical problems, the utility model provides a multifunctional air fryer, including a body, a cooking cavity arranged in the body, and a hot air circulation system connected to the cooking cavity, the body is detachably provided with a box body with an inner cavity, the inner cavity including a first inner cavity and a second inner cavity; the body is provided with an infusion system, the infusion system includes the water delivery system and the oil delivery system respectively connecting the cooking cavity with the first inner cavity and the second inner cavity, the oil delivery system includes an oil pump, an oil nozzle extending into the cooking cavity, and an oil delivery pipeline connecting the second inner cavity and the oil pump and the oil nozzle, the oil delivery pipeline includes a first oil delivery pipeline, both ends of the first oil delivery pipeline are provided with threaded connectors, the first oil delivery pipeline is suitable for being threadedly connected to the oil pump and the oil nozzle through the connector. The air fryer is provided with the first inner cavity and the second inner cavity in the box body, and the water supply system and the oil supply system are provided in the body body, which respectively connect the cooking cavity with the first cavity and the second cavity. The air fryer can replenish oil and / or water to the food in the cooking cavity by filling oil and water in the first cavity and the second cavity respectively, which not only effectively improves the functional diversity and applicability of the air fryer, but also effectively improves the user convenience and improves the user experience. At the same time, since the pressure required for atomizing the oil is relatively large, by providing the connectors with threads at both ends of the first oil pipeline to be threadedly connected to the oil pump and the oil spray head respectively, the connection strength and connection stability of the first oil pipeline with the oil pump and the oil spray head can be effectively guaranteed, and the situation that the first oil pipeline is separated from the oil pump and the oil spray head due to excessive internal pressure of the first oil pipeline can be avoided, thereby effectively improving the performance stability of the oil supply system and the safety of use of the air fryer.

[0005] In an optional embodiment, the oil spray head is provided with an outwardly extending annular flange on its outer side, and a connector is provided on one side of the annular flange that is movably connected to the oil spray head. A duct plate is provided on the top of the cooking cavity, and an oil spray hole is provided on the duct plate. The oil spray head is adapted to extend into the cooking cavity through the oil spray hole, and the connector and the annular flange are adapted to be positioned on either side of the oil spray hole, respectively, and abut against the duct plate on either side of the oil spray hole. The oil spray head is secured to the duct plate by the connector, thereby preventing the oil spray head from being displaced or dislodged from the oil spray hole due to the kinetic energy generated by the instantaneous oil spraying, thereby ensuring the oil spraying stability of the oil spray head and effectively improving the oil replenishment and cooking effects of the air fryer.

[0006] In an optional embodiment, the connecting member has a first internal thread on its inner side, and the oil spray head has a first external thread on its outer side that matches the first internal thread. The connecting member is adapted to be threadedly connected to the oil spray head via the first internal thread and the first external thread. By threading the connecting member to the oil spray head, not only is the connection strength and stability between the connecting member and the oil spray head ensured, but also the connection strength and stability between the oil spray head and the air duct plate are ensured, effectively improving the performance and stability of the air fryer.

[0007] In an optional embodiment, the oil spray head includes a mounting base having an annular flange on its outer side and a nozzle body. The mounting base is provided with a mounting groove connected to the oil pipeline, and the inner sidewall of the mounting groove is provided with a second internal thread. One end of the nozzle body is provided with a connecting portion that extends into the mounting groove, and the outer side of the connecting portion is provided with a second external thread that matches the second internal thread. The connecting portion of the nozzle body is adapted to be threadedly connected to the mounting groove of the mounting base via the second internal thread and the second external thread. Threading the nozzle body to the mounting base not only effectively simplifies the structure of the oil spray head, reducing the production cost and user cost of the air fryer, but also effectively reduces the difficulty of disassembly and installation of the nozzle body, thereby facilitating disassembly, cleaning, and replacement of the nozzle body. Furthermore, the threaded connection between the nozzle body and the mounting base ensures the strength and stability of the connection between the nozzle body and the mounting base, effectively improving the oil spraying stability of the oil spray head and the performance stability of the air fryer.

[0008] In an optional embodiment, a nozzle cover is sleeved on the outside of the nozzle body, a third internal thread is provided on the inside of the nozzle cover, and a third external thread is provided on the outside of the nozzle body that matches the third internal thread. The nozzle cover is adapted to be threadedly connected to the nozzle body via the third internal thread and the third external thread. Threading the nozzle cover to the nozzle body not only reduces the difficulty of removing and installing the nozzle cover, facilitating removal, cleaning, and replacement of the nozzle cover, but also effectively simplifies the structure of the oil spray head, reducing the production cost and user cost of the air fryer.

[0009] In an optional embodiment, an annular sealing gasket made of an elastic, high-temperature-resistant material is further sheathed on the outer side of the oil spray head, and the connecting member is adapted to abut the air duct plate via the sealing gasket. The sealing gasket is adapted to provide a sealing function, thereby achieving a sealed connection between the connecting member and the air duct plate, preventing high-temperature heat flow within the cooking cavity from escaping through the oil spray holes and out of the cooking cavity, thereby affecting the normal operation of electrical components outside the cooking cavity. Furthermore, the sealing gasket is adapted to provide a buffering function. By providing the sealing gasket between the connecting member and the air duct plate, the effect of kinetic energy generated by the oil spray head during oil spraying on the oil spray head is reduced, effectively ensuring the stability of the oil spray head and its connection to the air duct plate.

[0010] In an optional embodiment, an upper mechanism is provided above the cooking cavity, the upper mechanism being provided with a receiving groove compatible with the oil pump. The oil pump is adapted to be positioned within the receiving groove, and a fixing member made of an elastic material compatible with the oil pump is provided on the outside of the oil pump, the oil pump being secured within the receiving groove by the fixing member. The oil pump generates significant kinetic energy during operation. By placing the oil pump within the receiving groove and securing it with the fixing member made of an elastic material, not only is the kinetic energy generated by the operating oil pump prevented from affecting electrical components surrounding the oil pump, but the impact of the kinetic energy generated by the operating oil pump on the oil pump itself is also reduced, effectively ensuring the performance stability of the oil pump and the air fryer.

[0011] In an optional embodiment, a sealing groove is provided on the inner or outer side of the connector, and a sealing ring made of an elastic material is disposed within the sealing groove. The connector is adapted to sealably engage with the oil pump and the oil spray head via the sealing ring. The sealing ring is adapted to provide a seal, thereby achieving a sealed connection between the connector, the oil pump, and the oil spray head. This not only effectively ensures the normal operation of the oil delivery system, but also prevents oil leakage from the connection between the connector, the oil pump, and the oil spray head due to excessive pressure in the first oil delivery pipeline, thereby effectively improving the performance stability and operational safety of the oil delivery system.

[0012] In an optional embodiment, the first oil pipeline is suitably made of a high-pressure-resistant metal or non-metallic material. Because atomizing oil requires high pressure, high pressure is generated within the first oil pipeline during operation of the oil delivery system. Using a high-pressure-resistant metal or non-metallic material to construct the first oil pipeline can reduce the impact of the high pressure within the first oil pipeline on the pipeline itself, ensuring normal oil delivery and effectively improving the oil delivery stability of the oil delivery system.

[0013] In an optional embodiment, the water supply system includes a water pump, a water nozzle extending into the cooking cavity, and a water supply pipeline connecting the first inner cavity with the water pump and the water nozzle. The water supply pipeline includes a first water supply pipeline, and the outer sides of the first water supply pipeline are provided with tightenable fasteners. The two ends of the first water supply pipeline are respectively plugged into the water pump and the water nozzle, and are fixedly connected to the water pump and the water nozzle by the fasteners. By plugging the two ends of the first water supply pipeline into the water pump and the water nozzle and fixing them with the fasteners, not only can the structure of the water supply system be effectively simplified and the difficulty of disassembly and installation of the first water supply pipeline be reduced, but the connection strength of the first water supply pipeline to the water pump and the water nozzle can also be ensured, effectively improving the water supply stability of the water supply system and the performance stability of the air fryer.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] The present application provides the first inner cavity and the second inner cavity in the box body, and provides the water delivery system and the oil delivery system in the body that respectively connect the cooking cavity with the first cavity and the second cavity, so that the food in the cooking cavity can be replenished with oil and / or water by filling the first inner cavity and the second inner cavity respectively, which can not only effectively improve the functional diversity and applicability of the air fryer, but also effectively improve the user convenience and improve the user experience; at the same time, since the pressure required for atomizing the oil is relatively large, by providing the threaded connectors at both ends of the first oil delivery pipeline to be threadedly connected to the oil pump and the oil spray head respectively, the connection strength and connection stability of the first oil delivery pipeline with the oil pump and the oil spray head can be effectively guaranteed, and the situation that the first oil delivery pipeline is separated from the oil pump and the oil spray head due to excessive internal pressure of the first oil delivery pipeline can be avoided, thereby effectively improving the performance stability of the oil delivery system and the safety of use of the air fryer.

[0026] Attachment Figure 1 To the attached Figure 4 2 is a schematic diagram of a multifunctional air fryer provided by the present invention. The air fryer includes a body 10, a cooking cavity 11 provided in the body 10, and a hot air circulation system 20 connected to the cooking cavity 11. A frying basket with an open top is provided in the cooking cavity 11, and the frying basket is suitable for placing food to be cooked. The hot air circulation system 20 is suitable for generating a circulating heat flow and passing it into the cooking cavity 11 to heat the food in the frying basket.

[0027] like Figures 1 to 3As shown, the body 10 is detachably provided with a box body 30 having an inner cavity 31, and the inner cavity 31 includes a first inner cavity 311 and a second inner cavity 312; the body 10 is provided with an infusion system 40, and the infusion system 40 includes a water delivery system 41 and an oil delivery system 42, and the water delivery system 41 and the oil delivery system 42 are suitable for connecting the cooking cavity 11 with the first inner cavity 311 and the second inner cavity 312 respectively. The air fryer is provided with the first inner cavity 311 and the second inner cavity 312 in the housing 30, and the water supply system 41 and the oil supply system 42 are provided in the body 10 to connect the cooking cavity 11 with the first inner cavity 311 and the second inner cavity 312, respectively. Therefore, the food in the cooking cavity 11 can be replenished with oil and / or water by filling the first inner cavity 311 and the second inner cavity 312, respectively. This can not only effectively improve the functional diversity and applicability of the air fryer, but also effectively improve the user convenience and improve the user experience.

[0028] like Figures 2 to 4 As shown, the oil delivery system 42 includes an oil pump 421, an oil nozzle 422 extending into the cooking cavity 11, and an oil delivery pipeline 423 connecting the second inner cavity 312 and the oil pump 421 and the oil nozzle 422. The oil delivery pipeline 423 includes a first oil delivery pipeline 4231 and a second oil delivery pipeline. The first oil delivery pipeline 4231 is provided with a threaded connector 424 at both ends. The first oil delivery pipeline 4231 is suitable for being threadedly connected to the oil pump 421 and the oil nozzle 422 through the connector 424. The second oil delivery pipeline is suitable for being connected to the second inner cavity 312 and the oil pump 421 at both ends. When the air fryer is working, the oil pump needs to produce oil. Only when a larger pressure is generated can the oil in the oil pump be pressed into the first oil pipeline and sprayed out in atomized form through the oil nozzle. Therefore, by arranging the connectors 424 with threads at both ends of the first oil pipeline 4231 to be threadedly connected to the oil pump 421 and the oil nozzle 422 respectively, the connection strength and connection stability of the first oil pipeline 4231 and the oil pump 421 and the oil nozzle 422 can be effectively guaranteed, and the situation that the first oil pipeline 4231 is separated from the oil pump 421 and the oil nozzle 422 due to excessive internal pressure of the first oil pipeline 4231 can be avoided, thereby effectively improving the performance stability of the oil delivery system 40 and the safety of use of the air fryer.

[0029] like Figure 4As shown, in an optional embodiment, an annular flange 4221 extending outward is provided on the outer side of the oil spray head 422, and a connecting piece 425 that can be movably sleeved on the oil spray head 422 is provided on one side of the annular flange 4221; an air duct plate 12 is provided on the top of the cooking cavity 11, and an oil spray hole 121 is provided on the air duct plate 12, and the oil spray head 422 is suitable for extending into the cooking cavity 11 through the oil spray hole 121, and the connecting piece 425 and the annular flange 4221 are suitable for being respectively located on both sides of the oil spray hole 121, and abutting against the air duct plate 12 on both sides of the oil spray hole 121. The air fryer fixes the oil nozzle 422 to the air duct plate 12 through the connecting piece 425, which can prevent the oil nozzle 422 from being offset or detaching from the oil spray hole 121 due to the kinetic energy generated by the oil nozzle 422 at the moment of oil spraying, thereby ensuring the oil spraying stability of the oil nozzle 422 and effectively improving the oil replenishment effect and cooking effect of the air fryer.

[0030] like Figure 4 As shown, in an optional embodiment, the connecting member 425 has a first internal thread on its inner side, and the oil spray head 422 has a first external thread on its outer side that matches the first internal thread. The connecting member 425 is adapted to be threadedly connected to the oil spray head 422 via the first internal thread and the first external thread. By threading the connecting member 425 to the oil spray head 422, not only is the connection strength and stability between the connecting member 425 and the oil spray head 422 ensured, but also the connection strength and stability between the oil spray head 422 and the air duct plate 12 are ensured, effectively improving the performance and stability of the air fryer.

[0031] like Figure 4As shown, in an optional embodiment, the oil nozzle 422 includes a mounting seat 4222 with the annular flange 4221 on the outside and a nozzle body 4223, the mounting seat 4222 is provided with a mounting groove connected to the oil pipeline 423, and the inner side wall of the mounting groove is provided with a second internal thread, and one end of the nozzle body 4223 is provided with a connecting portion that can extend into the mounting groove, and the outer side of the connecting portion is provided with a second external thread matching the second internal thread, and the connecting portion of the nozzle body 4223 is suitable for being threadedly connected to the mounting groove of the mounting seat 4222 through the second internal thread and the second external thread. By threading the nozzle body 4223 to the mounting seat 4222, not only can the structure of the oil spray head 422 be effectively simplified and the production cost and user cost of the air fryer be reduced, but the difficulty of disassembly and installation of the nozzle body 4223 can also be effectively reduced, so as to facilitate the disassembly, cleaning and replacement of the nozzle body 4223; at the same time, the threaded connection between the nozzle body 4223 and the mounting seat 4222 can also ensure the connection strength and connection stability of the nozzle body 4223 and the mounting seat 4222, thereby effectively improving the oil spraying stability of the oil spray head 422 and the performance stability of the air fryer.

[0032] like Figure 4 As shown, in an optional embodiment, a nozzle cover 4224 is sleeved on the outside of the nozzle body 4223, a third internal thread is provided on the inside of the nozzle cover 4224, and a third external thread matching the third internal thread is provided on the outside of the nozzle body 4223. The nozzle cover 4224 is adapted to be threadedly connected to the nozzle body 4223 via the third internal thread and the third external thread. By threading the nozzle cover 4224 to the nozzle body 4223, not only is the difficulty of disassembly and installation of the nozzle cover 4224 reduced, facilitating disassembly, cleaning, and replacement of the nozzle cover 4224, but the structure of the oil spray head 422 is also effectively simplified, thereby reducing the production cost and user cost of the air fryer.

[0033] like Figure 4As shown, in an optional embodiment, an annular sealing gasket 426 made of an elastic, high-temperature-resistant material such as rubber or silicone is further sheathed on the outer side of the oil spray head 422. The connector 425 is adapted to abut the air duct plate 12 via the sealing gasket 426. The sealing gasket 426 is adapted to provide a sealing function, thereby achieving a sealed connection between the connector 425 and the air duct plate 12, preventing the high-temperature heat flow within the cooking cavity 11 from escaping through the oil spray holes 121 and out of the cooking cavity 11, thereby affecting the normal operation of electrical components outside the cooking cavity 11. Furthermore, the sealing gasket 426 is adapted to provide a buffering function. By providing the sealing gasket 426 between the connector 425 and the air duct plate 12, the kinetic energy generated by the oil spray head 422 during oil spraying can be reduced, thereby effectively ensuring the stability of the oil spraying and connection between the oil spray head 422 and the air duct plate 12.

[0034] like Figure 3 and Figure 4 As shown, in an optional embodiment, an upper mechanism 13 is disposed above the cooking cavity 11. The upper mechanism 13 is provided with a receiving groove 131 that matches the oil pump 421. The oil pump 421 is adapted to be disposed within the receiving groove 131. Furthermore, a fixing member 427 made of an elastic material such as rubber or silicone is disposed on the outer side of the oil pump 421 and matches the oil pump 421. The oil pump 421 is adapted to be secured within the receiving groove 131 by the fixing member 427. The oil pump 421 generates significant kinetic energy during operation. By placing the oil pump 421 within the receiving groove 131 and securing it with the fixing member 427, the kinetic energy generated by the oil pump 421 during operation is prevented from affecting electrical components surrounding the oil pump 421 and also reduces the impact of the kinetic energy generated by the oil pump 421 on the oil pump 421 itself, effectively ensuring the performance stability of the oil pump 421 and the air fryer.

[0035] like Figure 4As shown, in an optional embodiment, a sealing groove 4241 is provided on the outside of the connector 424, and a sealing ring 428 made of an elastic material such as rubber or silicone is provided in the sealing groove 4241. The connector 424 is adapted to be sealed with the oil pump 421 and the oil spray head 422 through the sealing ring 428. The sealing ring 428 is adapted to function as a seal, and the sealing ring 428 can realize a sealed connection between the connector 424, the oil pump 421, and the oil spray head 42, which can not only effectively ensure the normal operation of the oil delivery system 42, but also prevent the oil from leaking from the connection between the connector 424, the oil pump 421, and the oil spray head 422 due to excessive pressure in the first oil delivery pipeline 4231, thereby effectively improving the performance stability and use safety of the oil delivery system 42. In addition, in another optional embodiment, when the connecting head 424 is sleeved on the outer side of the connecting end of the oil pump 421 and the oil nozzle 422, the sealing groove 4241 is suitable for being arranged on the inner side of the connecting head 424, and the sealing ring 428 is suitable for being arranged in the sealing groove 4241 to seal with the oil pump 421 and the oil nozzle 422, and the above-mentioned effect can also be achieved.

[0036] In an optional embodiment, the first oil pipeline 4231 is preferably made of a high-pressure-resistant metal or non-metallic material, such as stainless steel, copper alloy, or PTFE. In the air fryer, due to the high pressure required to atomize the oil, high pressure is generated within the first oil pipeline 4231 during operation of the oil delivery system 42. By using a high-pressure-resistant metal or non-metallic material for the first oil pipeline 4231, the impact of the high pressure within the first oil pipeline 4231 on the first oil pipeline 4231 itself can be reduced, ensuring normal oil delivery and effectively improving the oil delivery stability of the oil delivery system 42.

[0037] like Figure 3As shown, in an optional embodiment, the water supply system 41 is suitable for including a water pump 411, a water nozzle 412 extending into the cooking cavity 11, and a water supply pipeline 413 connecting the first inner cavity 311 and the water pump 411 and the water nozzle 412. The water supply pipeline 413 includes a first water supply pipeline 4131 and a second water supply pipeline. The two ends of the first water supply pipeline 4131 are respectively provided with a tightenable fastener 414 on the outside. The two ends of the first water supply pipeline 4131 are suitable for being respectively inserted into the water pump 411 and the water nozzle 412, and are fixedly connected to the water pump 411 and the water nozzle 412 by the fastener 414. The two ends of the second water supply pipeline are suitable for respectively connecting the first inner cavity 311 and the water pump 411. By respectively plugging the two ends of the first water supply pipeline 4131 into the water pump 411 and the water nozzle 412, and fixing them with the fasteners 414, not only can the structure of the water supply system 41 be effectively simplified and the difficulty of disassembly and installation of the first water supply pipeline 4131 be reduced, but also the connection strength between the first water supply pipeline 4131 and the water pump 411 and the water nozzle 412 can be ensured, thereby effectively improving the water supply stability of the water supply system 41 and the performance stability of the air fryer.
