Description

Technical Field

[0001] The present invention relates to the field of kitchen appliances, and particularly to a multifunctional air fryer. Background Art

[0002] An air fryer is a kitchen cooking appliance that combines baking, frying, etc., and can quickly heat and crispify food, and can produce a crispy and fried taste without using oil.

[0003] A pressure cooker has a unique high-temperature and high-pressure function, which can shorten the cooking time and save energy. The food cooked in a pressure cooker has a soft taste.

[0004] Currently, consumers have higher standards for the choice of food cooking methods and the taste of food. For this reason, there has emerged a cooking utensil that combines an air fryer and a pressure cooker on the market.

[0005] Existing products are composed of a pot body, an air fryer lid, and a pressure cooker lid, with a complex structure, occupying a large space, being inconvenient to operate and store, and moreover, their pressure monitoring uses an NTC to detect steam and then convert it into pressure data, with a high cost. Summary of the Invention

[0006] The purpose of the present invention is to provide a multifunctional air fryer in which the lid and the pot body can be separated and which has the functions of an air fryer and a pressure cooker.

[0007] The purpose of the present invention is achieved as follows:

[0008] A multifunctional air fryer includes a lid, a pot body, and an inner lid assembly, and is characterized in that: the lid includes a baking device, a micro switch, a first magnet, and an upper coupler, the first magnet is fixed on the lid, the upper coupler is arranged on the lid in a movable manner, and the baking device and the normally open micro switch are respectively electrically connected to the upper coupler;

[0009] The pot body is provided with a control panel and a lower coupler, the pot body is provided with a first reed switch corresponding to the position of the first magnet, the pot body is provided with a heating device, and the first reed switch, the lower coupler, and the heating device are respectively electrically connected to the control panel;

[0010] The inner lid assembly is detachably installed in the lid, and the inner lid assembly touches and turns on the micro switch;

[0011] When the lid is buckled on the pot body, the first magnet approaches the first reed switch, and the control panel monitors that the first reed switch is in the on state;

[0012] When the upper coupler and the lower coupler are in the off state, the control panel controls the start and stop of the heating device and controls the state of the heating device;

[0013] When the upper coupler and the lower coupler are in a connected state, the control panel simultaneously disconnects the power supply of the heating device and the baking device.

[0014] The pot lid and the pot body are separated. The control panel controls the start and stop of the heating device and adjusts the temperature of the heating device within the heating range of the heating device to form a stir-frying mode, and the user can stir-fry ingredients in the pot body.

[0015] The pot lid does not install the inner lid assembly. When the pot lid and the pot body are buckled and the upper coupler and the lower coupler are connected, the control panel disconnects the power supply of the heating device. At the same time, the control panel controls the start and stop of the baking device and adjusts the state of the baking device to form an air fryer mode, and the user can bake ingredients in the pot body.

[0016] The pot lid installs the inner lid assembly. When the pot lid and the pot body are buckled and the upper coupler and the lower coupler are disconnected, the control panel controls the start and stop of the heating device and adjusts the temperature of the heating device within the heating range and pressure range of the heating device to form a pressure cooker mode, and the user can cook ingredients in the pot body.

[0017] Thus, the pot has a stir-frying mode, an air fryer mode and a pressure cooker mode, with diverse functions, which improves the practicality of the pot.

[0018] Moreover, if the inner lid assembly is not installed in the pressure cooker mode, the control panel disconnects the power supply of the heating device. If the inner lid assembly is installed in the air fryer mode, the control panel simultaneously disconnects the power supply of the heating device and the baking device, avoiding the simultaneous start of the heating device and the baking device, and improving safety.

[0019] The object of the present invention can also be solved by the following technical measures:

[0020] As a more specific solution, the pot lid further includes a second magnet, the pot body further includes a second reed switch, the second reed switch is electrically connected to the control panel, and the inner lid assembly pushes the second magnet away from the second reed switch, and the control panel monitors that the second reed switch is in an open state.

[0021] As a more specific solution, a push rod extending toward the pot body is provided at the switch position of the pot lid close to the micro switch. The inner lid assembly pushes the push rod, and the push rod touches the switch position of the micro switch to turn on the micro switch. The inner lid assembly pushes the push rod, and the push rod touches the switch position of the micro switch to turn on the micro switch, and the principle is simple.

[0022] As a more specific solution, the pot lid is further provided with a lever, the lever is rotatably arranged in the pot lid, the lever extends toward the pot body direction to form a lifting part, one end of the lever is provided with the second magnet, and the inner lid assembly pushes the lifting part, causing the lever to rotate and the second magnet to move away from the second reed switch.

[0023] As a more specific solution, it further includes a pressure switch and an elastic diaphragm. The elastic diaphragm is arranged at the bottom of the pot body, and the feet of the heating device abut against the elastic diaphragm. The elastic diaphragm supports the heating device upwards. The pressure switch is arranged below the elastic diaphragm near the feet and is electrically connected to the control panel. During the process of cooking food, if the pressure value of the pot body is too high, the pressure pushes the heating device to press down the elastic diaphragm, causing the elastic diaphragm to deform, so that the feet of the heating device press the pressure switch, resulting in the disconnection of the pressure switch, and the control panel disconnects the power supply of the heating device, improving the use safety.

[0024] As a more specific solution, the pot cover is provided with an exhaust valve and a float valve. The exhaust valve and the float valve are installed on the pot cover. The end of the exhaust valve extends into the inner cavity of the pot cover. The inner cover assembly is provided with a through hole, and the end of the exhaust valve passes through the through hole, and the exhaust valve positions the inner cover assembly. The inner cover assembly is provided with a through hole, and the end of the exhaust valve passes through the through hole, and the exhaust valve positions the inner cover assembly, avoiding the misalignment of the installation of the inner cover assembly and making the installation of the inner cover assembly more accurate.

[0025] As a more specific solution, the inner cavity of the pot cover is provided with insertion holes along its circumferential direction, and a snap ring assembly is arranged at the outlet of the insertion holes. The top of the inner cover assembly is provided with fixing columns along its circumferential direction, and handles are arranged at intervals along the circumferential direction at the bottom of the inner cover assembly. The fixing columns are inserted into the insertion holes, and the snap ring assembly clamps the fixing columns, realizing that the inner cover assembly is clamped on the pot cover. The fixing columns of the inner cover assembly are inserted into the insertion holes of the pot cover, and the snap ring assembly clamps the fixing columns, so that the inner cover assembly is connected to the pot cover.

[0026] As a more specific solution, the snap ring assembly includes a snap ring fixing block and a snap ring. The snap ring fixing block is arranged at the outlet of the insertion hole, the snap ring is installed in the snap ring fixing block, the inner cavity of the snap ring and the inner cavity of the insertion hole are communicated. The upper part of the fixing column is an upper frustum, the lower part of the fixing column is a lower frustum, and the upper frustum and the lower frustum are connected to form a fixing column with a narrow upper part, a wide middle part and a narrow lower part. The side wall of the upper frustum forms an upper inclined surface for facilitating the expansion of the snap ring, the side wall of the lower frustum forms a lower inclined surface for facilitating the expansion of the snap ring, and a limiting convex part is formed at the connection of the upper frustum and the lower frustum. The fixing column extends into the insertion hole and is inserted into the snap ring. The lower inclined surface is located in the inner cavity of the snap ring, and there is a gap between the lower inclined surface and the inner cavity of the snap ring. The limiting convex part sits on the snap ring, realizing that the snap ring supports the fixing column upwards. It enables the inner cover assembly to float up and down for adjustment, making the sealing effect between the inner cover assembly and the inner pot better. When the inner cover assembly and the pot cover are separated, pull the handle downwards with force, the lower inclined surface of the fixing column expands the snap ring, the diameter of the snap ring is larger than the diameter of the limiting convex part, and the fixing column can easily slide out of the snap ring, and the fixing column disengages from the snap ring, making it easier for the user to disassemble the inner cover assembly.

[0027] As a more specific solution, the pot lid is provided with an upper coupler accommodation cavity. A button is provided at the top of the pot lid corresponding to the position of the upper coupler accommodation cavity. The upper coupler is movably arranged in the upper coupler accommodation cavity and connected to the button. By pressing the button, the button drives the upper coupler to extend out of the upper coupler accommodation cavity to connect with the lower coupler, realizing the connection between the upper coupler and the lower coupler. Or the button drives the upper coupler to retract into the upper coupler accommodation cavity to disconnect from the lower coupler, realizing the disconnection between the upper coupler and the lower coupler. The upper coupler adopts a telescopic structure, which avoids the upper coupler from hindering the rotation and locking of the pot lid to the pot body. At the same time, the user can drive the upper coupler to extend out of the upper coupler accommodation cavity to connect with the lower coupler or retract into the upper coupler accommodation cavity to disconnect from the lower coupler through the button, adjust the functions of the air fryer, and improve the practicability of the air fryer.

[0028] As a more specific solution, the button is provided with an M-shaped elastic sheet. Convex columns are provided at both end parts of the M-shaped elastic sheet. The button is a hollow cylinder. The M-shaped elastic sheet is installed in the inner cavity of the button, and the convex columns pass through the outer wall of the button. The pot lid is provided with a button accommodation cavity above the upper coupler accommodation cavity. The inner wall of the button accommodation cavity is provided with upper concave holes and lower concave holes. The button and the spring are placed in the button accommodation cavity. One end of the spring abuts against the button, and the other end of the spring abuts against the inside of the button accommodation cavity. The spring constitutes the reset mechanism of the button. When the button is not pressed, the upper coupler and the lower coupler are disconnected, and the convex column is inserted into the upper concave hole to lock the button. When the button is pressed, the upper coupler and the lower coupler are connected, and the convex column is inserted into the lower concave hole to lock the button. This avoids the button from resetting and maintains the connected state of the upper coupler and the lower coupler, preventing the pressure of the pot body from pushing the button to reset during the cooking process. If the user needs to disconnect the upper coupler and the lower coupler, the user needs to pull the button upwards forcefully to cause the M-shaped elastic sheet to deform, and the convex column leaves the lower concave hole until the convex column enters the upper concave hole to lock the button. The operation is simple, which greatly improves the working stability of the multifunctional air fryer.

[0029] As a more specific solution, the inner lid assembly includes an inner lid, a sealing ring and a pressing ring. The sealing ring is sleeved on the inner lid, and the pressing ring is installed on the inner lid to press the sealing ring tightly. The inner lid is provided with the through hole, and the fixing columns are arranged at intervals along the circumferential direction of the inner lid. The lifting handles are arranged at intervals along the circumferential direction of the pressing ring. The pressing ring is installed on the inner lid to press the sealing ring tightly, preventing the sealing ring from loosening.

[0030] As a more specific solution, the pot lid is provided with lid teeth, and the upper open part of the pot body is provided with pot teeth. The pot lid is placed on the pot body. By rotating the pot lid, the lid teeth and the pot teeth are engaged with each other, realizing the buckling of the pot lid and the pot body and the mutual locking of the pot lid and the pot body.

[0031] As a more specific solution, the baking device includes a heating device tube, a fan and a reflector. The heating device tube, the fan and the reflector are located on the pot lid.

[0032] As a more specific solution, a buzzer is provided on the pot body, and the buzzer is electrically connected to the control panel. In the pressure cooker mode, if the inner lid assembly is not installed, the control panel activates the buzzer, and the buzzer emits a sound to remind the user. In the air fryer mode, if the inner lid assembly is installed redundantly, the control panel activates the buzzer, and the buzzer emits a sound to remind the user.

[0033] The beneficial effects of the present invention are as follows:

[0034] In the present invention, when the pot lid and the pot body are separated, the control panel controls the start and stop of the heating device and adjusts the temperature of the heating device within the heating range of the heating device, forming a stir-frying mode, and the user can stir-fry food ingredients in the pot body. When the inner lid assembly is not installed on the pot lid, and the pot lid and the pot body are buckled and the upper coupler and the lower coupler are connected, the control panel disconnects the power supply of the heating device. At the same time, the control panel controls the start and stop of the baking device and adjusts the state of the baking device to form an air fryer mode, and the user can bake food ingredients in the pot body. When the inner lid assembly is installed on the pot lid, and the pot lid and the pot body are buckled and the upper coupler and the lower coupler are disconnected, the control panel controls the start and stop of the heating device and adjusts the temperature of the heating device within the heating range and the pressure range of the heating device to form a pressure cooker mode, and the user can cook food ingredients in the pot body. Thus, the pot has a stir-frying mode, an air fryer mode and a pressure cooker mode, with diverse functions, improving the practicality of the pot.

[0035] In the present invention, if the inner lid assembly is not installed in the pressure cooker mode, the control panel disconnects the power supply of the heating device. If the inner lid assembly is installed redundantly in the air fryer mode, the control panel disconnects the power supply of the heating device and the baking device at the same time, avoiding the simultaneous start of the heating device and the baking device, and improving safety.

[0036] In the present invention, when the inner lid assembly is installed on the pot lid, it can form a pressure cooker lid. When the inner lid assembly is separated from the pot lid, it can form an air fryer lid. Thus, the pot lid, the inner lid assembly and the pot body can be assembled to form a pressure cooker or an air fryer, with simple operation. Moreover, in the pressure cooker mode, if the inner lid assembly is not installed, the control panel activates the buzzer, and the buzzer emits a sound to remind the user. In the air fryer mode, if the inner lid assembly is installed redundantly, the control panel activates the buzzer, and the buzzer emits a sound to remind the user. Description of the Drawings

A limiting convex part 56 is formed at the connection of the upper frustum 541 and the lower frustum 542.

[0071] Working principle:

[0072] Stir-frying mode:

[0073] When the pot lid 1 leaves the pot body 2, the first magnet 7 and the first reed switch 22 are disconnected, the second magnet 71 and the second reed switch 81 are disconnected, the upper coupler 11 and the lower coupler 21 are disconnected. The control panel 24 monitors that both the first reed switch 22 and the second reed switch 81 are in the disconnected state, and the control panel 24 controls the start and stop of the heating device 25, adjusts the temperature of the heating device 25 within the heating gear range of the heating device 25, and turns off the buzzer 82.

[0074] Air fryer mode:

[0075] The user seats the inner pot 3 in the pot body 2, then seats the pot lid 1 on the pot body 2, and then the user rotates the pot lid 1 until the lid teeth 14 of the pot lid 1 and the pot teeth 23 of the pot body 2 are tightly clamped with each other, realizing the fastening of the pot lid 1 and the pot body 2.

[0076] At this time, the first magnet 7 of the pot lid 1 approaches the first reed switch 22 of the pot body 2, the second magnet 71 approaches the second reed switch 81, the upper coupler 11 and the lower coupler 21 are aligned, and the control panel 24 monitors that both the first reed switch 22 and the second reed switch 81 are in the connected state.

[0077] At this time, the user presses the button 16, and the button 16 drives the upper coupler 11 to move downward, realizing the connection of the upper coupler 11 and the lower coupler 21. The control panel 24 monitors that the micro switch 6 is in the disconnected state. At this time, the control panel 24 disconnects the power supply of the heating device 25, and the control panel 24 connects the power supply of the baking device 4 and controls the state of the baking device 4.

[0078] At this time, the user adjusts by touching the control panel 24 to freely change the temperature of the baking device 4, and then can bake the food in the inner pot 3, and the operation is simple.

[0079] When the air fryer mode is adopted, the baking device 4 emits heat, resulting in a very high temperature at the position of the retaining spring 192 of the pot lid 1. The present invention adopts a metal retaining spring fixing block and a metal retaining spring, and utilizes the characteristics of the metal being heat-resistant and having a long service life to prevent the retaining spring 192 from deforming.

[0080] Air fryer mode (when the inner lid assembly 5 is installed more):

[0081] Inner lid assembly 5 installed more: The inner lid assembly 5 pushes up the lifting part 78, causing the lever 72 to rotate upwards, the second magnet 71 to move away from the second reed switch 81, the second reed switch 81 to disconnect, and at the same time the inner lid assembly 5 pushes the ejector rod 13 to act, and the ejector rod 13 touches the switch position of the micro switch 6 to turn on the micro switch 6.

[0082] The user seats the inner pot 3 in the pot body 2, then seats the pot lid 1 on the pot body 2, and then the user rotates the pot lid 1 until the lid teeth 14 of the pot lid 1 and the pot teeth 23 of the pot body 2 are tightly engaged with each other, achieving the buckling of the pot lid 1 and the pot body 2, and the first magnet 7 of the pot lid 1 approaches the first reed switch 22 of the pot body 2.

[0083] The user presses the button 16, and the button 16 drives the upper coupler 11 to move downwards to connect the upper coupler 11 and the lower coupler 21. The control panel 24 monitors that the first reed switch 22 is in the on state, the second reed switch 81 is in the off state, and the micro switch 6 is in the on state. The control panel 24 simultaneously disconnects the power supply of the heating device 25 and the baking device 4, and the buzzer 82 is activated to prevent the heating device 25 and the baking device 4 from starting simultaneously, improving safety, and the buzzer 82 emits a sound to remind the user.

[0084] Pressure cooker mode:

[0085] The user places the inner lid assembly 5 in the pot lid 1, adjusts the position of the inner lid assembly 5, and positions the inner lid assembly 5 by passing the exhaust valve 9 through the through hole 511 of the inner lid assembly 5.

[0086] Then, the fixing column 54 of the inner lid assembly 5 is inserted into the jack 18 of the pot lid, and the upper inclined surface 5411 of the upper round table 541 gradually expands the snap ring 192 until the diameter of the snap ring 192 is greater than the diameter of the limiting convex part 56. The fixing column 54 is completely inserted into the jack 18, and the lower inclined surface 5422 of the fixing column 54 is located inside the snap ring 192. At this time, the snap ring 192 resumes, resulting in the diameter of the snap ring 192 being smaller than the diameter of the limiting convex part 56. At this time, the limiting convex part 56 sits on the snap ring 192, and the snap ring 192 supports the fixing column 54 upwards and restricts the fixing column 54 in the jack 18, achieving the connection between the inner lid assembly 5 and the pot lid 1. The operation is simple. The inner lid assembly 5 pushes the ejector rod 13 to act, and the ejector rod 13 touches the switch position of the micro switch 6 to turn on the micro switch 6.

[0087] Due to the gap 10 between the snap ring 192 and the lower inclined surface 5422 of the fixing column 54, and the limiting convex part 56 sitting on the snap ring 192, the inner lid assembly 5 can be adjusted up and down. When pressure is generated in the pot, the inner lid assembly 5 can be automatically aligned with the inner pot 3, making the sealing effect between the inner lid assembly 5 and the inner pot 3 better.

[0088] Moreover, the inner lid assembly 5 pushes the lifting part 78 upward, causing the lever 72 to rotate upward, the second magnet 71 to move away from the second reed switch 81, and the second reed switch 81 to disconnect.

[0089] Next, the user places the inner pot 3 into the pot body 2 and the pot lid 1 on the pot body 2. The user rotates the pot lid 1 until the lid teeth 14 of the pot lid 1 and the pot teeth 23 of the pot body 2 are tightly engaged, achieving the fastening of the pot lid 1 and the pot body 2. At the same time, the inner pot 3 pushes the inner lid assembly 5 to move, making the sealing ring 52 closely adhere to the inner pot 3, improving the sealing effect. At this time, the first magnet 7 of the pot lid 1 approaches the first reed switch 22 of the pot body 2.

[0090] When the user does not press the button 16, the upper coupler 11 and the lower coupler 21 are in the disconnected state. The control panel 24 monitors that the first reed switch 22 is in the on state and the second reed switch 81 is in the off state. The control panel 24 controls the start and stop of the heating device 25 and adjusts the temperature of the heating device 25 within the range of the heating gear and the pressure gear of the heating device 25.

[0091] The user can adjust by touching the control panel 24 to freely change the temperature of the heating device 25, and then cook the food in the inner pot 3. The operation is simple. When a large pressure is generated during the cooking process of the food, the pressure causes the inner pot 3 to move downward. Since the elastic diaphragm 26 is the weakest part, the downward movement of the heating device 25 causes the elastic diaphragm 26 to deform. The downward movement of the inner pot 3 causes the heating device 25 to move downward, and the heating device 25 presses the pressure switch 27 until the pressure switch 27 disconnects, and the control panel 24 stops the heating of the heating device 25, improving the safety of use.

[0092] Pressure Cooker Mode (Inner Lid Assembly Missing)

[0093] The micro switch 6 of the pot lid 1 is in the off state. At the same time, the lever 72 swings downward under the action of gravity, the second magnet 71 approaches the second reed switch 81, and the second reed switch 81 is turned on.

[0094] The user places the inner pot 3 into the pot body 2 and the pot lid 1 on the pot body 2. The user rotates the pot lid 1 until the lid teeth 14 of the pot lid 1 and the pot teeth 23 of the pot body 2 are tightly engaged, achieving the fastening of the pot lid 1 and the pot body 2. At the same time, the inner pot 3 pushes the inner lid assembly 5 to move, making the sealing ring 52 closely adhere to the inner pot 3, improving the sealing effect.

[0095] At this time, the first magnet 7 of the pot lid 1 approaches the first reed switch 22 of the pot body 2, and at the same time, the upper coupler 11 and the lower coupler 21 are aligned. The control panel 24 monitors that the first reed switch 22 is in the on state and the second reed switch 81 is in the on state. The control panel starts the buzzer 82 and disconnects the power supply of the heating device 25, and the buzzer 82 emits a sound to remind the user.

[0096] Inadvertently pressing button 16 in pressure cooker mode:

[0097] If the user accidentally presses the button 16 when using the pressure cooker function, the button 16 drives the upper coupler 11 to move downward, thereby connecting the upper coupler 11 and the lower coupler 21. At this time, the control panel 24 detects that the micro switch 6 is in the on state, the first reed switch 22 is in the on state, and the second reed switch 81 is in the on state. The control panel 24 disconnects the power supply of the heating device 25 and the power supply of the baking device 4 to avoid simultaneous startup of the heating device 25 and the baking device 4, thereby improving safety. At the same time, the buzzer 82 is activated and emits a sound to remind the user.

[0098] Remove the inner cover assembly 5:

[0099] When the user turns the pot cover 1 upside down and pulls the handle 55 outward, the inner cover assembly 5 moves upward and away from the pot cover 1. During the sliding process of the inner cover assembly 5, the lower inclined surface 5422 of the fixing column opens the retaining spring 192. The diameter of the retaining spring 192 is larger than the diameter of the limiting protrusion 56. The fixing column 54 can easily slide out of the retaining spring 192. When the fixing column 54 is separated from the retaining spring 192, the inner cover assembly 5 can be taken out, making it easier for the user to disassemble the inner cover assembly 5.

[0100] Upper and lower couplers connected:

[0101] Combine Figures 15 to 16 When the user presses the button 16, the spring 17 is deformed, and the protrusion 301 of the button 16 is inserted into the lower recessed hole 202 to lock the button 16, preventing the button 16 from resetting, maintaining the upper coupler 11 and the lower coupler 21 in a connected state, and preventing the pressure of the pot body 2 from pushing the button 16 to reset during the cooking process, thereby improving working stability.

[0102] Upper and lower couplers disconnected:

[0103] Combine Figures 18 to 19 The user needs to pull the button 16 upward with force, and the spring 17 resets, causing the M-shaped spring 300 to deform, and the boss 301 leaves the lower recessed hole 202 until the boss 301 enters the upper recessed hole 201 to lock the button 16. The operation is simple and the working stability is improved.
