Description

Technical Field

[0001] This application belongs to the field of vacuum cooking technology, and in particular relates to a vacuum fryer. Background Technology

[0002] A vacuum fryer is a device that processes food by frying it under negative pressure (vacuum). Its core principle is to utilize the physical property that a vacuum environment lowers the boiling point of liquids, causing the cooking oil to boil at a lower temperature and thus frying the food. This method combines the advantages of preserving the flavor and nutrients of the food with reducing its oil content. A vacuum fryer typically includes a pot assembly, a frying basket, and a tray. The tray is rotatably mounted inside the pot assembly, and the frying basket is placed on the tray to hold the food to be processed.

[0003] Currently, the frying basket inside the vacuum fryer can rotate with the tray when the tray rotates, but the matching structure between the frying basket and the tray makes it inconvenient for users to quickly place the frying basket on the tray. Utility Model Content

[0004] The purpose of this application is to provide a vacuum fryer to solve the technical problem in the prior art that it is inconvenient for users to quickly place the frying basket on the tray.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides a vacuum fryer, including a pot body assembly, a drive device, a tray, and a frying basket, wherein: one end of the drive device extends into the pot body assembly and is sealed to the pot body assembly, and the tray is connected to the end of the drive device that extends into the pot body assembly; the frying basket is supported on the tray and the two are snap-fitted together, and the snap-fitting connection between the frying basket and the tray can be released when the frying basket is rotated in a preset direction.

[0006] In this embodiment, since the tray is connected to one end of the drive device that extends into the pot assembly, the drive device can rotate the tray when it operates. When the frying basket needs to be removed from the pot assembly, the tray is stationary. The user only needs to rotate the frying basket in a preset direction to release the engagement between the frying basket and the tray, and then lift the frying basket upwards. When placing the frying basket on the tray, the user does not need to engage the frying basket on the tray. After placing the frying basket on the tray, the user starts the vacuum fryer. When the drive device rotates the tray in a preset direction, it can rotate until it engages with the frying basket, and then the tray can rotate together with the frying basket.

[0007] In some implementations, the bottom of the frying basket has a protrusion, the tray includes a middle part and a connecting arm, one end of the connecting arm is connected to the middle part, and a snap-fit ​​interface is provided on one side of the connecting arm along the circumference of the tray. The protrusion can be inserted into the snap-fit ​​interface to realize the snap-fit ​​connection between the tray and the frying basket.

[0008] In this implementation, the frying basket and the tray are connected by a protrusion and a snap-fit ​​interface, which makes the connection structure simple and facilitates the processing of the frying basket and the tray.

[0009] In some implementations, there are two or more connecting arms, each evenly spaced along the circumferential direction of the central region, and each connecting arm has a card interface on the same side along the circumferential direction of the central region; the number of protrusions is the same as the number of connecting arms, and each protrusion mates with a corresponding card interface.

[0010] In this implementation, by setting two or more connecting arms and the number of protrusions being the same as the number of connecting arms, the frying basket can be stably rotated together when the tray rotates. In addition, when there are multiple protrusions, the frying basket can be supported on the table by the protrusions at the bottom, which can accelerate the drainage of moisture / oil from the food in the frying basket, improve the taste and hygiene of the food, and make the user experience better.

[0011] In some implementations, the blasting basket includes a blasting basket body, a first connector and a second connector. The blasting basket body is provided with a mating hole. The first connector is located inside the blasting basket body and inserted into the mating hole. The second connector is located below the blasting basket body and connected to the first connector. The second connector forms a protrusion.

[0012] In this implementation, the blasting basket includes a blasting basket body, a first connector and a second connector, and a protrusion formed by the first connector. This not only improves the strength of the protrusion but also facilitates the assembly of the blasting basket.

[0013] In some implementations, the first connector and the second connector are threaded together.

[0014] In this implementation, the first connector and the second connector are connected by threads to facilitate the assembly and disassembly of the first connector; at the same time, rotating the first connector and the second connector also facilitates the adjustment of the height of the protrusion.

[0015] In some implementations, the bottom surface of the blasting basket body has a first groove recessed towards the inside of the blasting basket body, and a matching hole is set on the bottom surface of the first groove.

[0016] In this implementation, a first groove is formed on the bottom surface of the blast basket body, which is recessed inward towards the inside of the blast basket body. This helps to improve the strength of the blast basket body at the position where the first connector and the second connector are connected. At the same time, it also helps to reduce the height of the protrusion of the protrusion from the bottom surface of the blast basket body.

[0017] In some implementations, a second groove is formed at the bottom of the frying basket, which is recessed into the basket, and a positioning protrusion is formed on the tray, which protrudes towards the frying basket and is inserted into the second groove.

[0018] In this implementation, the frying basket and the tray are positioned in the radial direction by setting a positioning protrusion and a second groove, so that when the frying basket is placed on the tray, the card interface can be inserted into the protrusion when the tray rotates, thereby causing the frying basket to rotate together when the tray rotates.

[0019] In some implementations, the vacuum fryer also includes an oil cup, and an oil guide pipe is provided at the bottom of the pot assembly, which connects the pot assembly and the oil cup. An electric valve body is provided on the oil guide pipe. The inner bottom surface of the pot assembly includes a central area and a circumferential area, which are connected to the circumferential edge of the central area. One end of the oil guide pipe is connected to the circumferential area. Along the direction from the central area to the circumferential area, the height of the central area decreases.

[0020] In this implementation, by setting the height of the middle region to decrease along the direction from the middle region to the circumferential region, and by connecting one end of the oil guide pipe to the circumferential region, the oil in the pot assembly can be concentrated in the direction of the circumferential region, thereby facilitating the flow of the oil to the oil cup through the oil guide pipe.

[0021] In some implementations, the pot assembly includes a pot body, a heat-conducting plate, and a heating device. The pot body includes a bottom and a side. The side is connected to the circumferential edge of the bottom. The bottom is made of metal. The heat-conducting plate is located outside the pot body and connected to the bottom. The heating device is located on the heat-conducting plate.

[0022] In this implementation, by setting the bottom of the pot body to be made of metal and installing a heat-conducting plate with a heating device on the bottom of the pot body, it is beneficial to quickly heat the food in the frying basket.

[0023] In some implementations, the drive device includes a drive motor, a connecting joint, and a rotating body. The drive motor is located below the pot body assembly. The connecting joint connects the output shaft of the drive motor and the rotating body. The rotating body is inserted into the pot body assembly and is sealed to the pot body assembly. The tray is fixed on the rotating body. When the drive motor is activated, the tray can be rotated through the connecting joint and the rotating body.

[0024] In this implementation, the driving device includes a drive motor, a connecting joint, and a rotating body to drive the frying basket to rotate relative to the pot assembly.

[0025] In some implementations, the vacuum fryer also includes a housing, with the pot assembly housed within the housing; the vacuum fryer also includes a support frame, with multiple studs at the bottom of the pot assembly, and connectors passing through the support frame and inserted into the studs for threaded connection with the studs.

[0026] In this implementation, multiple studs are provided at the bottom of the pot body assembly to facilitate detachable connection with the support frame, thereby making it convenient to assemble and disassemble the pot body assembly. Attached Figure Description

[0071] This application provides a vacuum fryer 100, which is a device for frying food in a negative pressure (vacuum) environment. The core principle is to utilize the physical property of "vacuum environment lowers the boiling point of liquid" to make edible oil boil at a lower temperature and complete the frying of food.

[0072] Please see Figure 4 The vacuum fryer 100 provided in this application embodiment includes a cover 20, a shell 10, a pot assembly 30, and a cup 40. The cover 20 is disposed on the shell 10 and can be rotatably connected to the shell 10. The pot assembly 30 is disposed inside the shell 10, and the cup 40 is supported on the shell 10.

[0073] See some examples. Figure 1 A portion of the front side of the housing 10 has an inwardly recessed storage cavity 11, and two cups 40 are arranged side-by-side in the storage cavity 11. For details, please refer to... Figure 2 The housing 10 includes a first housing portion 12 and a second housing portion 13. The first housing portion 12 is connected to the second housing portion 13. The second housing portion 13 is located on the front side of the first housing portion 12 and near the upper end of the first housing portion 12. The lower side of the second housing portion 13 and the front side of the first housing 10 form a storage cavity 11 for accommodating the cup body 40. The lid 20 is located above the second housing portion 13 and the two are connected. The second housing 10 internally accommodates the pot assembly 30. Please refer to [link to relevant documentation]. Figure 4 The second housing part 13 includes a support plate assembly 131, which is disposed below the pot body assembly 30, and the two cup bodies 40 are connected to the support plate assembly 131.

[0074] Of the two cups 40, one cup 40 is used to collect the oil inside the pot assembly 30, and the other cup 40 collects the condensate generated during vacuum frying. For ease of description, the cup 40 used to collect the oil is called the oil cup 42, and the cup 40 used to collect the condensate is called the water cup 41. Please refer to [link to relevant documentation]. Figure 4 This illustrates oil cup 42 and water cup 41; please refer to [link / reference]. Figure 4 The support plate assembly 131 is provided with a vacuum connector 132, which is used to connect to the vacuum pumping device of the vacuum fryer 100. In some examples, the vacuum pumping device includes a vacuum pump and multiple vacuum pipes. The water cup 41 is connected to three vacuum connectors 132 on the support plate assembly 131, and the oil cup 42 is connected to one vacuum connector 132 (not shown in the figure) on the support plate assembly 131. For ease of description, please refer to [link to relevant documentation]. Figure 4The three vacuum connectors 132 connected to the inside of the water cup 41 are respectively referred to as the first vacuum connector 1321, the second vacuum connector 1322, and the third vacuum connector 1323. The first vacuum connector 1321 is connected to the mating connector on the pot body assembly 30 or the lid 20 through a vacuum pipe. The vacuum connector 132 connected to the oil cup 42 is connected to the second vacuum connector 1322 through a vacuum pipe. The third vacuum connector 1323 is connected to the vacuum pump through a vacuum pipe. When the pump is working, a vacuum can be drawn on the pot body assembly 30, the water cup 41, and the oil cup 42. In addition, a condensing device is provided on the vacuum pipe connecting the first vacuum connector 1321 and the mating connector. The condensing device is used to condense the air discharged from the pot body assembly 30, and the condensate produced by condensation flows to the water.

[0075] In some examples, the lid 20 is provided with a fitting connector that mates with the vacuum pipe, and the fitting connector is connected to the interior of the pot assembly 30. When the vacuum fryer 100 performs low-temperature frying under vacuum, the water in the food will boil rapidly, and because the air pressure inside the pot assembly 30 is very low, it will quickly turn into bubbles. The boiling state of the oil will be more intense than that of frying at room temperature. If a fitting connector is provided on the pot assembly 30, a lot of oil will be drawn away along the vacuum pipe, resulting in oil waste. However, using a fitting connector on the lid 20 will improve the situation of oil waste caused by oil boiling.

[0076] See some examples. Figure 5 The cover 20 includes an upper cover 21 and a lower cover 22. The upper cover 21 is located above the lower cover 22 and the two are connected. There is a space between the upper cover 21 and the lower cover 22. The lower cover 22 is provided with a vacuum hole 221, which is used to install a mating joint for connecting a vacuum pipe.

[0077] See some examples. Figure 4 The second housing part 13 includes a top plate assembly 133, which is disposed above the pot body assembly 30. The top plate assembly 133 is rotatably connected to the cover 20. The top plate assembly 133 is provided with a clearance hole to avoid the pot body assembly 30, and a pot body sealing ring 120 is provided on the top edge of the pot body assembly 30. The pot body sealing ring 120 extends upward out of the clearance hole and seals with the cover 20.

[0078] See some examples. Figure 4An oil guide pipe 80 is provided between the pot body assembly 30 and the support plate assembly 131. The oil guide pipe 80 is connected to the inside of the oil cup 42. An electric valve body 90 is provided on the oil guide pipe 80. When it is necessary to drain the oil in the pot body assembly 30 to the oil cup 42, the electric valve body 90 can be opened, so that the oil in the pot body assembly 30 flows to the oil cup 42 through the oil guide pipe 80 under the action of gravity. After the oil is drained, the electric valve body 90 can be closed.

[0079] See some examples. Figure 4 The oil guide pipe 80 includes a first pipe section 81 and a second pipe section 82. The first pipe section 81 is connected to the pot body assembly 30, and the second pipe section 82 is connected to the support plate assembly 131. The electric valve body 90 is connected to the second pipe section 82 and the second pipe section 82.

[0080] Please see Figures 6-8 , Figure 6 This is a partial structural schematic diagram of a vacuum fryer 100 provided in some embodiments of this application. Figure 7 This is a schematic diagram of the structure of the pot body assembly 30 and the tray 60 provided in some embodiments of this application. Figure 8 This is a schematic diagram of the structure of the frying basket 50 provided in some embodiments of this application.

[0081] The vacuum fryer 100 provided in this application embodiment also includes a drive unit 70, a tray 60, and a frying basket 50. Please refer to [link to relevant documentation]. Figure 6 The diagram illustrates the drive device 70, one end of which extends into and is sealed to the pot body assembly 30. Please refer to [link to relevant documentation]. Figure 7 The diagram illustrates that the tray 60 is disposed within the pot body assembly 30. The tray 60 is connected to one end of the drive device 70 that extends into the pot body assembly 30. When the drive device 70 is activated, it can drive the tray 60 to rotate relative to the pot body assembly 30. Please refer to [link / reference]. Figure 8 The diagram shows the frying basket 50, which can be placed inside the pot assembly 30 and supported on the tray 60, or the frying basket 50 can be removed from the pot assembly 30.

[0082] In some examples, the frying basket 50 is a wire mesh basket; or, in other examples, see [link to relevant documentation]. Figure 8 The bottom and sides of the frying basket 50 are provided with several oil drain holes 514, meaning that the frying basket 50 is made by processing a perforated metal plate.

[0083] In this embodiment, the frying basket 50 can be snapped onto the tray 60, and the snapping connection between the frying basket 50 and the tray 60 can be released when the frying basket 50 is rotated in a preset direction.

[0084] This can be understood as the drive unit 70 driving the tray 60 along the first direction (i.e., Figure 7(In the direction indicated by the middle arrow a) When the frying basket 50 is attached to the tray 60, the drive device 70 can rotate the tray 60 and the frying basket 50 together in the first direction. When the frying basket 50 rotates, it is beneficial for the food in the frying basket 50 to be heated evenly, and it is also beneficial for the food in the frying basket 50 to be dehydrated and deoiled.

[0085] In this embodiment, when the frying basket 50 is placed on the tray 60, the user does not need to snap the frying basket 50 onto the tray 60. After the user places the frying basket 50 on the tray 60 and starts the vacuum fryer 100, the drive device 70 drives the tray 60 to rotate in the first direction until it snaps onto the frying basket 50. Then the tray 60 can drive the frying basket 50 to rotate together. When it is necessary to remove the frying basket 50 from the pot assembly 30, the tray 60 is in a stationary state. The user only needs to rotate the frying basket 50 in the preset direction (i.e., the first direction) to release the snap between the frying basket 50 and the tray 60. The user can then lift the frying basket 50 upwards.

[0086] In some embodiments, see Figure 6 The vacuum fryer 100 also includes a support frame 110, with both ends of the support frame 110 connected to the housing 10. The bottom of the pot assembly 30 is provided with a plurality of studs 34, each stud 34 being supported on the support frame 110. The studs 34 are provided with threaded holes. Connectors such as screws or bolts pass through the support frame 110 and are inserted into the studs 34 to be threadedly connected to the studs 34, thereby enabling the pot assembly 30 to be detachably connected to the support frame 110.

[0087] In some examples, studs 34 may be welded to the bottom of the pot assembly 30.

[0088] In this embodiment, a plurality of studs 34 are provided at the bottom of the pot body assembly 30 to facilitate a detachable connection with the support frame 110, thereby facilitating the assembly and disassembly of the pot body assembly 30.

[0089] Please see Figures 9-11 , Figure 9 This is a schematic diagram of the structure of the tray 60 provided in some embodiments of this application. Figure 10 This is a top view of the frying basket 50 provided in some embodiments of this application. Figure 11 This is a partial schematic diagram showing the cooperation between the protrusion 54 on the frying basket 50 and the tray 60 in some embodiments of this application.

[0090] In some embodiments, see Figure 10 The bottom of the frying basket 50 has a protrusion 54, please refer to [link / reference]. Figure 9The tray 60 includes a middle part 61 and a connecting arm 62. One end of the connecting arm 62 is connected to the middle part 61. A card interface 621 is provided on one side of the connecting arm 62 along the circumferential direction of the tray 60. The protrusion 54 can be inserted into the card interface 621 to realize the card connection between the tray 60 and the frying basket 50.

[0091] Please see Figure 11 This illustrates that the protrusion 54 is located at the locking interface 621. When the frying basket 50 is placed on the tray 60, the user does not need to lock the protrusion 54 at the bottom of the frying basket 50 onto the locking interface 621 on the tray 60. After the user places the frying basket 50 on the tray 60 and starts the vacuum fryer 100, the drive device 70 rotates the tray 60 in the first direction until the locking interface 621 on the tray 60 is inserted into the protrusion 54 at the bottom of the basket. Then the tray 60 can rotate the frying basket 50 together. When it is necessary to remove the frying basket 50 from the pot assembly 30, the user only needs to rotate the frying basket 50 in the preset direction (i.e., the first direction) so that the protrusion 54 disengages from the locking interface 621.

[0092] See some examples. Figure 11 The protrusion 54 includes a protrusion head 541 and a protrusion body 542. The protrusion head 541 is located on the side of the protrusion body 542 away from the bottom surface of the frying basket 50. The diameter of the protrusion head 541 is larger than that of the protrusion body 542. When the protrusion 54 is engaged with the card interface 621 on the tray 60, the protrusion body 542 is inserted into the card interface 621.

[0093] In this embodiment, the frying basket 50 and the tray 60 are connected by a protrusion 54 and a snap-fit ​​interface 621. The connection structure is simple and facilitates the processing of the frying basket 50 and the tray 60.

[0094] In some embodiments, see Figure 10 The bottom of the frying basket 50 has a second groove 513 that is recessed into the interior of the frying basket 50. Please refer to [link / reference]. Figure 9 A positioning protrusion 611 is formed on the tray 60, protruding towards the frying basket 50, and the positioning protrusion 611 is inserted into the second groove 513.

[0095] See some examples. Figure 10 The second groove 513 is formed in the middle of the blasting basket 50, please refer to [link / reference]. Figure 9 The positioning protrusion 611 is formed on the middle part 61, and the positioning protrusion 611 is located in the middle position of the middle part 61.

[0096] When the frying basket 50 is about to be placed on the tray 60, the positioning protrusion 611 on the middle part 61 needs to be inserted into the second groove 513 to position the frying basket 50 on the tray 60 in the radial direction. This allows the card interface 621 on the tray 60 to be inserted into the protrusion 54 at the bottom of the frying basket 50 when the drive device 70 rotates the tray 60.

[0097] See some examples. Figure 9 The positioning protrusion 611 on the middle part 61 is truncated cone-shaped, and the second groove 513 matches the shape of the positioning protrusion 611 so as to facilitate placing the frying basket 50 on the tray 60.

[0098] In some examples, the positioning protrusion 611 on the tray 60 is stamped, and the second groove 513 on the frying basket 50 is stamped.

[0099] In this embodiment, the frying basket 50 and the tray 60 are positioned in the radial direction by the positioning protrusion 611 and the second groove 513, so that when the frying basket 50 is placed on the tray 60, the card interface 621 can be inserted into the protrusion 54 when the tray 60 rotates, thereby causing the frying basket 50 to rotate together when the tray 60 rotates.

[0100] In some embodiments, there are two or more connecting arms 62, each connecting arm 62 is evenly spaced along the circumferential direction of the middle region 35, and a card interface 621 is provided on the same side of each connecting arm 62 along the circumferential direction of the middle region 35; the number of protrusions 54 is the same as the number of connecting arms 62, and each protrusion 54 cooperates with the corresponding card interface 621.

[0101] See some examples. Figure 9 There are three connecting arms 62, which are evenly spaced along the circumferential direction of the central region 35. Each connecting arm 62 is provided with a card interface 621, which is located on the same side of each connecting arm 62; please refer to Figure 10 The bottom of the frying basket 50 has three protrusions 54, and two of the protrusions 54 are evenly spaced along the circumferential direction of the frying basket 50.

[0102] See some examples. Figure 9 The connecting arm 62 can be set to be in the shape of a long strip, and the card interface 621 can be in the shape of an arc.

[0103] It should be noted that the distance from the center of the card interface 621 to the central axis of the tray 60 is basically equal to the distance from the center of the protrusion 54 to the central axis of the frying basket 50, so that when the frying basket 50 is positioned on the tray 60, the card interface 621 can be inserted into the protrusion 54 when the tray 60 is rotated.

[0104] In this embodiment, by setting two or more connecting arms 62 and the number of protrusions 54 being the same as the number of connecting arms 62, the frying basket 50 can be stably rotated together when the tray 60 rotates. In addition, when there are multiple protrusions 54, the frying basket 50 can be supported on the table by the protrusions 54 at the bottom, which can accelerate the drainage of moisture / oil from the food in the frying basket 50, improve the taste and hygiene of the food, and make the user experience better.
