Description

Technical Field

[0001] This utility model relates to the field of air fryer technology, specifically to a split-type air fryer that can identify different pot bodies. Background Technology

[0002] Currently, top-loading air fryers consist of a top-loading main unit and a glass frying drum, with the main unit mounted on top of the drum. The volume of the glass frying drum is fixed. If the preset volume of the glass frying drum is suitable for a single person's meal, it cannot meet the needs of a family of multiple people. If the preset volume of the glass frying drum is intended for multiple family members, then for a single person's use, the glass frying drum is too large and the cooking efficiency is low.

[0003] Subsequent air fryer improvements included the use of glass frying drums of varying sizes in conjunction with the main unit. However, these improvements had limitations. They couldn't recognize different glass frying drums, resulting in inconsistent cooking outcomes for the same program depending on the drum's size, potentially leading to undercooked or burnt food. Furthermore, for safety, it was necessary to address the issue of ensuring the main unit operated correctly after the glass frying drum and main unit were properly installed, and to resolve the issue of recognizing different glass frying drums and the main unit in place. Utility Model Content

[0004] The purpose of this invention is to provide a split-type air fryer that can identify different pot bodies.

[0005] The purpose of this utility model is achieved as follows.

[0006] A split-type air fryer that identifies different pot bodies includes a head assembly and a frying drum assembly. The head assembly is detachably attached to the top of the frying drum assembly. A downward-heating device is located at the bottom of the head assembly. The head assembly contains a first switch assembly, a second switch assembly, and a third switch assembly electrically connected to a control circuit board. The second and third switch assemblies are connected in parallel and each is connected in series with the first switch assembly. The control circuit board is electrically connected to the heating device. Each of the first, second, and third switch assemblies has a trigger unit at the bottom of the head assembly. The frying drum assembly includes an outer pot body, a first inner pot, and a second inner pot. The frying drum assembly has a first usage state and a second usage state.

[0007] In the first operating state, the first inner pot is placed inside the outer pot. After the machine head assembly and the frying bucket assembly are connected, the outer pot body triggers the first switch assembly, and the top of the first inner pot triggers the second switch assembly. The control circuit board then controls the heating device to heat the inner cavity of the first inner pot according to the preset first cooking program.

[0008] In the second usage state, the second inner pot is placed inside the outer pot. After the machine head assembly and the frying bucket assembly are connected, the outer pot body triggers the first switch assembly, and the top of the second inner pot triggers the third switch assembly. The control circuit board controls the heating device to heat the inner cavity of the second inner pot according to the preset first cooking program.

[0009] Furthermore, the first, second, and third switch assemblies each include a normally open micro switch, a mounting bracket, and a trigger element. The mounting bracket secures the micro switch within the head assembly, with the actuating end of the micro switch facing downwards. The bottom of the head assembly has a mounting step hole corresponding to the actuating end. The top of the trigger element abuts against the actuating end, and the bottom of the trigger element extends out through a mounting hole to form the trigger portion. The first, second, and third switch assemblies are easy to install and operate stably.

[0010] Furthermore, the bottom surface of the fryer head assembly is provided with a first annular stepped surface and a second annular stepped surface from the outside in. A heating cavity is provided within the second annular stepped surface. The trigger parts of the first, second, and third switch assemblies are all located on the second annular stepped surface. The heating device and the flow guiding device are located within the heating cavity. The opening profile of the heating cavity is smaller than the top opening profile of the second inner pot. After the fryer head assembly and the frying bucket assembly are connected, the top surface of the frying bucket assembly abuts against the first annular stepped surface, and the top surface of the first or second inner pot abuts against the second annular stepped surface. The flow guiding device delivers the heat generated by the heating device into the first or second inner pot. The heat generated inside the glass frying bucket is less likely to overflow into the outer pot.

[0011] Furthermore, the distance between the actuating part of the first switch assembly and the center of the machine head assembly is greater than the distance between the actuating part of the second switch assembly and the center of the machine head assembly, and the distance between the actuating part of the second switch assembly and the center of the machine head assembly is greater than the distance between the actuating part of the third switch assembly and the center of the machine head assembly. The positions of the first, second, and third switch assemblies are designed reasonably to detect whether the corresponding outer pot, first inner pot, and second inner pot are installed in place.

[0012] Furthermore, the first and second switch assemblies are located on opposite sides of the head assembly, and the third switch assembly is located on one of the other opposite sides of the head assembly. The positions of the first, second, and third switch assemblies are rationally arranged.

[0013] Furthermore, the top of the outer pot body is equipped with a locking device for securing the first inner pot. The hook portion of the locking device is snapped into place on the top of the first inner pot. A recess is provided at the bottom of the machine head assembly corresponding to the hook portion. The trigger portion of the first switch assembly is located within this recess. After the machine head assembly and the frying drum assembly are connected, the hook portion inserts into the recess and abuts against the trigger portion of the first switch assembly, triggering the first switch assembly. The hook portion is higher than the top of the first inner pot, ensuring that the outer pot body can activate the first switch assembly. The locking device prevents the first inner pot from detaching from the outer pot body on its own.

[0014] Furthermore, the outer pot body has a middle ring at the top. In the first use state, the first inner pot is fitted inside the middle ring. The top of the middle ring has a limiting hole, and the hook part extends upward through the limiting hole. The middle ring restricts the position of the first pot body and the hook part.

[0015] Furthermore, the locking device includes a locking element, a button section, a rotating shaft, and an elastic element. The middle part of the locking element is rotatably disposed in the inner cavity of the middle ring via the rotating shaft. The upper end of the locking element extends out a limiting hole to form the hook section. One end of the elastic element abuts against the inner side of the middle ring, and the other end of the elastic element pushes the lower end of the locking element to rotate outward from the middle ring, causing the hook section to rotate inward until the locking element abuts against the limiting hole. A mounting seat is provided on the outer side of the outer pot body. The button section is horizontally movably disposed in the mounting seat, with the outer end of the button section protruding from the mounting seat. The inner end of the button section extends through the outer pot body, the outer side of the middle ring, and abuts against the lower end of the locking element. The locking device has a simple structure and operates stably and reliably.

[0016] Furthermore, the mounting base has a horizontally positioned mounting hole, and a fixing seat is located near the outer end of the mounting hole. The fixing seat and the mounting hole are snap-fitted together. The fixing seat has a clearance hole for the outer end of the button to pass through. The button has a limiting part that abuts against the inner end of the fixing seat to limit movement. The mounting base constitutes the handle of the outer pot body. The button is easy to install, operates stably and reliably, and the integrated design of the button and handle provides a degree of concealment for the button, preventing accidental activation and resulting in a simpler overall appearance.

[0017] Furthermore, a support base is provided at the bottom of the inner cavity of the outer pot. In the first usage state, the bottom of the first inner pot sits on the support base. In the second usage state, the frying bucket assembly includes a bracket. The top surface of the support base has a positioning groove, and the bottom of the bracket has a positioning protrusion. The bracket sits on the top surface of the support base, and the positioning protrusion is inserted into the positioning groove to limit the horizontal displacement of the bracket. The second inner pot is fixedly seated within the bracket. The second inner pot is firmly fixed and not prone to horizontal displacement, ensuring that the third switch assembly can be accurately activated after the second inner pot is positioned and installed.

[0018] The outer pot body of this utility model must be assembled with the first inner pot or the second inner pot before it can be used with the machine head assembly. The machine head assembly can identify the first inner pot or the second inner pot so as to perform a preset cooking program according to its volume, ensuring reliable cooking results.

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0028] Example 1, see Figure 1-8 As shown, a split-type air fryer that identifies different pots includes a head assembly 1 and a frying bucket assembly 2, wherein the head assembly 1 is detachably attached to the top of the frying bucket assembly 2.

[0029] The bottom surface of the blasting head assembly 1 has a first annular stepped surface 11 and a second annular stepped surface 12 arranged sequentially from the outside to the inside. A heating cavity 13 is provided within the second annular stepped surface 12, and a heating device and a flow guiding device are housed within the heating cavity 13. A surrounding wall 14 is provided outside the first annular stepped surface 11 on the bottom surface of the blasting head assembly 1, and the surrounding wall 14 is fitted with a limiting engagement with the outer side of the top of the glass blasting barrel. A motor 15 and a cooling fan blade 16 are provided inside the blasting head assembly 1. The output shaft of the motor 15 drives the cooling fan blade 16 to rotate within the heat dissipation channel. The flow guiding device is located above the heating device and consists of a flow guiding fan blade 17. The output shaft of the motor 15 extends into the heating cavity 13, driving the flow guiding fan blade 17 to rotate. The heating device is an electric heating element 18.

[0030] The head assembly 1 houses a control circuit board 19, a first switch assembly 100, a second switch assembly 200, and a third switch assembly 300. The heating device, motor 15, first switch assembly 100, second switch assembly 200, and third switch assembly 300 are all electrically connected to the control circuit board 19. The second switch assembly 200 and the third switch assembly 300 are connected in parallel and both are connected in series with the first switch assembly 100. Each of the first switch assembly 100, second switch assembly 200, and third switch assembly 300 has a trigger part 104 at the bottom of the head assembly 1. Specifically, the first switch assembly 100, the second switch assembly 200, and the third switch assembly 300 each include a normally open micro switch 101, a mounting bracket 102, and a trigger element 103. The mounting bracket 102 fixes the micro switch 101 inside the head assembly 1, with the actuating end of the micro switch 101 facing downwards. The bottom of the head assembly 1 has a mounting step hole 10 corresponding to the actuating end. The top of the trigger element 103 abuts against the actuating end, and the bottom of the trigger element 103 extends out of the mounting hole to form the trigger portion 104. The trigger portions 104 of the first switch assembly 100, the second switch assembly 200, and the third switch assembly 300 are all located on the second annular step surface 12. During the triggering process of the first switch assembly 100, the second switch assembly 200, and the third switch assembly 300, the triggering part 104 moves upward, that is, the triggering element 103 moves upward and pushes the actuating end of the micro switch 101 within the mounting step hole 10, causing the micro switch 101 to enter the closed energized state from the normally open state. When the upward force of the triggering part 104 disappears, the micro switch 101 can automatically reset from the closed energized state to the normally open state. At the same time, the triggering element 103 moves downward under the action of gravity and / or the downward force of the actuating end of the micro switch 101 until the triggering element 103 and the step surface of the mounting step hole 10 come into contact and stop moving downward.

[0031] In this embodiment, the distance between the actuating part of the first switch assembly 100 and the center of the head assembly 1 is greater than the distance between the actuating part of the second switch assembly 200 and the center of the head assembly 1, and the distance between the actuating part of the second switch assembly 200 and the center of the head assembly 1 is greater than the distance between the actuating part of the third switch assembly 300 and the center of the head assembly 1. The first switch assembly 100 and the second switch assembly 200 are located on opposite sides of the head assembly 1, and the third switch assembly 300 is located on one of the other opposite sides of the head assembly 1.

[0032] The fryer assembly 2 includes an outer pot body 3, a first inner pot 4, a second inner pot 5, and a support 6. The bottom of the inner cavity of the outer pot body 3 is provided with a support base 31, and the top of the outer pot body 3 is provided with a central ring 32, with a limiting hole 33 at the top of the central ring 32. The top surface of the support base 31 is provided with a positioning groove 34, and the bottom of the support 6 is provided with a positioning protrusion 61. The support 6 sits on the top surface of the support base 31, and the positioning protrusion 61 is inserted into the positioning groove 34 to limit the horizontal displacement of the support 6. The support 6 is a wire frame, with a cavity formed inside the support 6 having an insertion port at the top. The support 6 also has a support portion 62 that is higher than the top surface of the support base 31. The second inner pot 5 is placed in the cavity through the insertion port, and the bottom of the second inner pot 5 sits on the support portion 62. The top periphery of the support 6 and the outer side of the second inner pot 5 are mutually limiting and fitted.

[0033] Two locking devices 7 are symmetrically arranged on opposite sides of the outer pot body 3. Each locking device 7 includes a locking element 71, a button portion 72, a rotating shaft 73, and an elastic element. The middle part of the locking element 71 is rotatably disposed within the inner cavity of the middle ring 32 via the rotating shaft 73. The upper end of the locking element 71 extends outward through a limiting hole 33 to form the hook portion 75. One end of the elastic element abuts against the inner side of the middle ring 32, while the other end pushes the lower end of the locking element 71 to rotate outward from the middle ring 32, causing the hook portion 75 to rotate inward until the locking element 71 abuts against the limiting hole 33. A mounting base 8 is provided on the outer side of the outer pot body 3. The button portion 72 is horizontally movably disposed within the mounting base 8, with its outer end protruding from the mounting base 8. The inner end of the button portion 72 extends through the outer pot body 3, the outer side of the middle ring 32, and abuts against the lower end of the locking element 71. In this embodiment, the elastic element is a torsion spring 74, which is sleeved on the rotating shaft 73. The bottom of the head assembly 1 has a recess 120 corresponding to the hook part 75, and the trigger part 104 of the first switch assembly 100 is located in a recess 120.

[0034] The mounting base 8 has a horizontally set mounting hole 81. A fixing seat 82 is provided near the outer end of the mounting hole 81. The fixing seat 82 and the mounting hole 81 are snap-fit ​​connected. The fixing seat 82 has a clearance hole 83 for the outer end of the button part 72 to pass through. The button part 72 has a limiting part 76. The limiting part 76 and the inner end of the fixing seat 82 abut against each other and limit the movement. The mounting base 8 constitutes the handle of the outer pot body 3.

[0035] The bottom of the inner cavity of the outer pot body 3 is provided with a support base 31. In the first use state, the bottom of the first inner pot 4 sits on the support base 31. In the second use state, the frying bucket assembly 2 includes a bracket 6. The top surface of the support base 31 is provided with a positioning groove 34. The bottom of the bracket 6 is provided with a positioning protrusion 61. The bracket 6 sits on the top surface of the support base 31. The positioning protrusion 61 is inserted into the positioning groove 34 to limit the horizontal displacement of the bracket 6. The second inner pot 5 is limited to sitting inside the bracket 6.

[0036] In this embodiment, the perimeter of the second inner pot 5 is smaller than that of the first inner pot 4, meaning the volume of the second inner pot 5 is smaller than that of the first inner pot 4. The opening profile of the heating cavity 13 is smaller than the top opening profile of the second inner pot 5. After the head assembly 1 and the frying bucket assembly 2 are connected, the top surface of the frying bucket assembly 2 (i.e., the top surface of the middle ring 32) abuts against the first annular step surface 11, and the top surface of the first inner pot 4 or the second inner pot 5 abuts against the second annular step surface 12. The guiding device delivers the heat generated by the heating device into the first inner pot 4 or the second inner pot 5. Both the first inner pot 4 and the second inner pot 5 are glass pots. Preferably, the outer pot body 3 is made of transparent plastic. Users can observe the food cooking process through the outer pot body 3 and the first inner pot 4 or the second inner pot 5.

[0037] The frying barrel assembly 2 has a first usage state and a second usage state.

[0038] In the first usage state, the first inner pot 4 is placed directly inside the outer pot body 3, and the first inner pot 4 is fitted inside the middle ring 32. The bottom of the first inner pot 4 sits on the support base 31. After the machine head assembly 1 and the frying bucket assembly 2 are connected, the locking part of the locking device 7 is snapped into the top surface of the first inner pot 4, and the hook part 75 is inserted into the recess 120 and abuts against the trigger part 104 of the first switch assembly 100, triggering the first switch assembly 100. At the same time, the top of the first inner pot 4 also triggers the second switch assembly 200. When the micro switch 101 of the first switch assembly 100 and the second switch assembly 200 changes from normally open to closed, the control circuit board 19 cooks according to the preset first cooking program (i.e., the large-capacity pot cooking program). The heating device of the machine head assembly 1 heats the inner cavity of the first inner pot 4, and a heat insulation layer 20 is formed between the outer pot body 3 and the first inner pot 4. When the frying barrel assembly 2 is disengaged, the microswitches 101 of the first switch assembly 100 and the second switch assembly 200 automatically reset, that is, return to the normally open state, and the machine head assembly 1 is de-energized and stops working, making it safer to use.

[0039] In the second usage state, the bottom of the bracket 6 is positioned on the support base 31, and the second inner pot 5 is positioned inside the bracket 6. After the machine head assembly 1 and the frying bucket assembly 2 are connected, the locking part of the locking device 7 abuts against the limiting hole 33, and the hook part 75 inserts into the recess 120 and abuts against the trigger part 104 of the first switch assembly 100, triggering the first switch assembly 100. At the same time, the top of the second inner pot 5 also triggers the third switch assembly 300. When the microswitches 101 of the first switch assembly 100 and the third switch assembly 300 change from normally open to closed, the control circuit board 19 cooks according to the preset second cooking program (i.e., the small-capacity pot cooking program), and the heating device of the machine head assembly 1 heats the inner cavity of the second inner pot 5. A heat insulation layer 20 is formed between the outer pot body 3 and the second inner pot 5. When the frying barrel assembly 2 is disengaged, the microswitches 101 of the first switch assembly 100 and the third switch assembly 300 automatically reset, that is, return to the normally open state, and the machine head assembly 1 is de-energized and stops working, making it safer to use.
