Description

A can dismantle grab handle device and air fryer for air fryer

Technical Field

The invention relates to the field of air fryers of kitchen appliances, in particular to a detachable grab handle device for an air fryer and a corresponding air fryer.

Background

With the increasing demands on food health, air fryers are becoming increasingly popular with consumers in non-fried food processing. An air fryer is a small household appliance that utilizes hot air high-speed circulation technology for cooking. In the frying process, the high-temperature air circulated at high speed in the air fryer takes away the moisture on the surface of the food and heats the food, so that the food is heated and cooked in the air fryer to achieve the taste and effect of frying, and therefore, compared with the traditional frying mode, the air fryer does not use extra grease, and the prepared food is healthier.

With the increasing development of air fryer designs, prior art air fryers generally include drawer-type air fryers and flip-type air fryers, wherein the drawer-type air fryers include a body with an opening, a cover disposed on the body, a fryer pot capable of being placed into the body from the opening, and a handle disposed on the fryer pot, and when cooking is finished, a user pulls the fryer pot out of the opening by holding the handle. However, such drawer-type air fryers currently suffer from certain drawbacks: to facilitate the user's pulling and holding of the fryer vat, the fryer's grip needs to extend a certain length toward the front side of the air fryer to provide sufficient torque. Thus, having a length of the grip inevitably increases the lateral external dimensions of the air fryer, causing on the one hand transport inconveniences and on the other hand also crowding kitchen space, and also extremely tedious disassembly work at the time of cleaning maintenance.

In view of the above, patent 201921996746.7 discloses a pull-type air fryer comprising a fryer body, a fryer assembly and a door assembly arranged outside the fryer assembly, wherein the lower part of the front side of the fryer body is provided with an opening, and the fryer body is provided with a cavity for accommodating the fryer assembly; the fryer assembly is drawably disposed within the cavity along the opening by a drawer assembly. While this construction avoids the problem of increased external lateral dimensions of the air fryer with the use of a handle device having a length, there are disadvantages: on the one hand, the lower opening at the front side of the pot body is pulled, so that the taking-out and pushing-in of the frying barrel can only be realized, and if force is applied to the opening to transfer the frying barrel after the frying barrel is taken out, the moment is too short, so that the labor is wasted; on the other hand, the downward design of the opening requires the user to push and pull the frying barrel in a palm-up mode, and is inconvenient to hold; in addition, the holding area is arranged on the outer wall of the frying barrel, and the outer wall is possibly broken or damaged after long-term use.

Therefore, there is a need to provide a reasonably designed removable grip for an air fryer that allows for quick removal while providing basic push-pull and transfer fryer pot functions, and that has sufficient strength to ensure durability for long periods of use.

Furthermore, references to "first" and "second" and the like in the following are for descriptive purposes only and are not to be construed as indicating or implying a sequence of importance or the number of technical features indicated.

The invention provides a detachable grab handle device for an air fryer.

Referring to fig. 1, 2 and 3, fig. 1 and 2 show exploded views of the fixed block assembly and the handle assembly of the detachable handle device from different angles, and fig. 3 shows a schematic perspective view of the detachable handle device.

The detachable grab handle device for the air fryer is mainly composed of a fixed block assembly 1, a heat insulation block assembly 2 and a grab handle assembly 3. Wherein, the inside coupling mechanism that has can dismantle fast of fixed block subassembly 1, the front panel of frying barrel is regarded as to the thermal-insulated piece subassembly 2 that has certain thickness, and it is provided with the structure with the quick dismantlement coupling mechanism looks adaptation of fixed block subassembly 1, and grab handle subassembly 3 is connected with fixed block subassembly 1 to provide the region that the convenience of customers held when taking out/pushing in frying barrel. When the fixed block assembly 1 is combined with the grab handle assembly 3, the integral structure formed by the fixed block assembly 1 and the grab handle assembly 3 can be detachably connected with the heat insulation block assembly 2.

Specifically, the fixed block assembly 1 is composed of a fixed block base 11, a first lock tongue 12 and a first rotating shaft 13. Wherein, fixed block base 11 is used for providing structural support for the detachable mechanism of grab handle subassembly 3 and thermal insulation block subassembly 2, and first spring bolt 12 is used for locking the overall structure after fixed block subassembly 1 and thermal insulation block subassembly 2 combine together to realize the conversion between locking and unblock through first pivot 13. A first locking structure 12a protruding outward is provided on the first locking tongue 12, and the entire structure is locked after the fixed block assembly 1 and the insulation block assembly 2 are combined so that they cannot be separated. At both sides of the fixing block base 11 are provided fixing block wings 11a for defining a mounting direction and providing support during the coupling of the fixing block assembly 1 and the insulation block assembly 2, respectively. Further, the first rotation shaft 13 serves as a rotation fulcrum, and rotatably connects the first tongue 12 with the fixed block base 11, so that the first tongue 12 can rotate clockwise and counterclockwise about the first rotation shaft 13 as a rotation axis.

Further, for convenience of description of the rotation range of the first latch tongue 12, two limit positions to which the first latch tongue 12 can rotate are defined as a first position and a second position, respectively. The first position is defined as the position of the first locking structure 12a farthest from the front surface of the fixed block base 11, at this time, the first lock tongue 12 is in the state of tilting furthest to the front, and the integral structure formed by combining the fixed block assembly 1 and the heat insulation block assembly 2 is locked and cannot move or separate from each other; correspondingly, the second position is defined as a position where the first locking structure 12a is closest to (or "close to") the front surface of the fixed block base 11, at this time, the first locking tongue 12 is in the most vertically abutted state, the integral structure formed by the fixed block assembly 1 and the heat insulation block assembly 2 is in the unlocked state, and the fixed block assembly 1 can longitudinally withdraw the heat insulation block assembly 2 along the movement direction defined by the fixed block wings 11 a.

Preferably, the first lock tongue 12 and the fixed block base 11 are respectively provided with corresponding rotating shaft holes so as to be matched with and install the first rotating shaft 13. The first lock tongue 12 is laterally provided with two first lock tongue rotation shaft holes 12d for the first rotation shaft 13 to pass through laterally. The fixed block base 11 is also provided with two fixed block rotating shaft holes 11d laterally, respectively, for the first rotating shaft 13 to pass laterally through the fixed block base 11. When the first lock tongue 12 is combined with the fixed block base 11, the projections of the two first lock tongue rotating shaft holes 12d and the two fixed block rotating shaft holes 11 in the horizontal direction coincide and are larger than the cross section area of the rotating shaft hole 13 so as to allow the first rotating shaft 13 to pass through. When the first shaft 13 is mounted, the first shaft 13, the two first bolt shaft holes 12d, and the two fixed block shaft holes 11d are connected together to form a connection mechanism that supports the first bolt 12 to rotate clockwise or counterclockwise at a certain angle relative to the fixed block base 11 with the first shaft 13 as a rotation axis. In addition, in order to ensure the structural strength of the detachable handle device in the locked state after locking and the durability under long-term use conditions, the first lock tongue 12 and the first rotating shaft 13 are preferably made of high-strength materials such as metal.

Further, the heat insulating block assembly is composed of a heat insulating block base 21, a fixed block limiting piece 22 and a heat insulating block front cover 23. Wherein, the heat insulation block base 21 is provided with a guide groove-shaped fixing block slot 21a, and the cross section shape of the grooved structure and the cross section shape of the protruding structure of the fixing block protruding wing 11a are mutually corresponding (that is, the two fixing block slots 21a arranged on the heat insulation block base 21 can accommodate the two fixing block protruding wings 11a positioned at two sides of the fixing block base 11 in a decibel manner, so that the two fixing block protruding wings 11a can slide in the grooves thereof), thereby limiting the sliding direction of the fixing block assembly 1 relative to the heat insulation block assembly 2 and providing support. The fixed block limiting piece 22 is disposed on the front side of the heat insulation block base 21, and is configured to cooperate with the first locking structure 12a protruding outwards in the first lock tongue 12, so that when the first lock tongue 12 is located at the first position, the first locking structure 12a and the fixed block limiting piece 22 mutually abut against each other to realize locking of the fixed block assembly 1 and the heat insulation block assembly 2. In addition, in order to ensure the structural strength of the detachable handle device in the locked state after locking and the durability under long-term use conditions, the first lock tongue 12, the fixed block limiting piece 22 and the first rotating shaft 13 are preferably made of metal materials, and the fixed block limiting piece 22 is also preferably fixedly connected with the heat insulation block base 21 through a threaded connection manner. The heat insulation block front cover 23 is used as a front side outer surface structure of the air fryer frying barrel, is formed by connecting the front side of the heat insulation block base 21 with the heat insulation block base 21 and is connected with the heat insulation block base 21 together to form a cavity with a certain thickness so as to isolate heat generated during cooking of the air fryer, and prevent scalding risks caused by overhigh temperature of the outer surface of the frying barrel.

Further, the handle assembly 3 forms a support for the air fryer vat mainly by the handle base 31 being connected to the fixed block assembly 1. It should be noted that the handle assembly 3 of the present invention is also provided with a locking mechanism for locking the fryer vat against pulling out of the air fryer body, as will be further explained in the detailed description of the second aspect of the invention.

Specifically, when the fixed block assembly 1 and the insulation block assembly 2 are in a coupled and locked state, there are the following features: the fixing block convex wings 11a of the first and the fixing block bases 11 protruding towards two sides are completely inserted into the corresponding two fixing block slots 21a in the heat insulation block base 21; the second and first locking bolts 12 are located at the first position (that is, the first locking bolt 12 rotates about the first rotation shaft 13 to a state that the first locking bolt 12 is tilted forward). When the fixed block assembly 1 and the heat insulation block assembly 2 are in a combined and locked state, the first locking structure 12a protruding outwards is mutually abutted with the fixed block limiting piece 22, and under the blocking of the fixed block limiting piece 22, the fixed block assembly 1 cannot drive the first lock tongue 12 to move upwards, and cannot drive the fixed block convex wing 11a to slide out of the heat insulation block base 21 upwards along the fixed block slot 21 a.

Specifically, when the fixed block assembly 1 and the insulation block assembly 2 are in an unlocked and separable state, there are the following features: the first and first locking tongues 12 rotate from a first position (i.e., the most tilted position relative to the fixed block base 11) to a second position (i.e., the most engaged position relative to the fixed block base 11) (in accordance with embodiments of the present invention, the direction of rotation is counter-clockwise in the right side view of the air fryer); second, under the drive of the first lock tongue 12, the locking structure 12a contracts downwards towards the side where the air fryer is located until the first locking structure 12a is no longer blocked by the fixed block limiting piece 22. When the fixed block assembly 1 and the heat insulation block assembly 2 are in the non-locking and separable state, the first locking structure 12a protruding outwards is not mutually abutted with the fixed block limiting piece 22 any more, so that the fixed block assembly 1 can drive the first lock tongue 12 to move upwards at the same time and drive the fixed block convex wing 11a to slide out of the heat insulation block base 21 upwards along the fixed block slot 21a under the condition that the fixed block limiting piece 22 is not blocked.

Further, in the present invention, a first lock tongue limit structure 11b is further provided in the fixed block base 11, and fig. 4 and 5 are combined, wherein fig. 4 shows a schematic perspective view of the fixed block assembly 1 after each part is combined and the handle assembly 3 after each part is combined in the detachable handle device, and fig. 5 shows a schematic perspective view of the fixed block base 11 in the detachable handle device. The first lock tongue limiting structure 11b is used for limiting the movement range of the first lock tongue 12, so that the first position is accurately limited to a specific angle to which the first lock tongue 12 rotates. As shown in fig. 1 and 3, the first locking bolt limiting structure 11b is disposed at the lower side of the fixed block base 11, is substantially in a hook-shaped structure, and is used for blocking the rotation range of the first locking bolt 12. When the first lock tongue 12 rotates toward the first position until reaching the limit position of the hook structure of the first lock tongue limit structure 11b (i.e., the position where the first position is located), the first lock tongue 12 cannot continue to rotate/tilt outward under the blocking of the first lock tongue limit structure 11 b.

Further, in order to facilitate the disassembly and assembly of the handle device by the user and avoid manual reset, the embodiment of the invention further provides a first reset spring 14 in the fixed block assembly 1, the first reset spring 14 is clamped between the first lock tongue 12 and the fixed block base 11, and in a preferred embodiment, spring posts matched with the first reset spring 14 are respectively arranged on the rear side surface of the first lock tongue 12 and the front side surface of the fixed block base 11, so as to ensure that the springs cannot accidentally fall off in daily use.

Specifically, the operating mechanism of the first return spring 14 has the following features: in one aspect, when the first latch tongue 12 is rotated to the second position (i.e., the position where the first latch tongue 12 is most closely attached to the fixed block base 11) by an external force, the first return spring 14 is compressed and contracted by the pushing of the first latch tongue 12; in another aspect, when the first return spring 14 is in a compressed state and the first lock tongue 12 is no longer pressed inward by the external force, the first return spring 14 rebounds under the action of the spring restoring force and pushes the first lock tongue 12 together to rotate toward the first position during the rebound, and finally when the first lock tongue 12 rotates to the first position (i.e. the position where the front lower end edge of the first lock tongue abuts against the hook-shaped structure of the first lock tongue limiting structure 11 b), the first lock tongue limiting structure 11b clamps the first lock tongue 12 together from the outside of the first lock tongue 12, and the first return spring 14 holds the first lock tongue 12 in the first position from the inside of the first lock tongue 12.

Further, to further simplify the manner of removal of the handle means, the insulation block assembly 2 is provided with an unlocking mechanism which enables a quick separation of the insulation block assembly 2 from the handle means. Referring to fig. 3 and 6 in combination, fig. 6 is a schematic perspective view of a combination of a fryer vat and a handle apparatus in an air fryer according to an embodiment of the invention. The front side surface of the front cover 23 of the heat insulation block is provided with a transversely penetrating unlocking hole 23a, when the handle device is combined into a whole, the unlocking hole 23a penetrates through the front side surface of the first lock tongue 12 (namely, the projection of the unlocking hole 23a along the opening direction of the unlocking hole is exactly projected on the front side surface of the first lock tongue 12), so that a user can realize quick disassembly of the handle device by inserting a thin strip-shaped object into the unlocking hole 23a to press the first lock tongue 12.

Specifically, when the user presses the first tongue 12 by inserting a thin strip-shaped object into the unlocking hole 23a, the first tongue 12 is rotated from the first position to the second position (i.e., the position where the first tongue 12 is most closely attached to the fixed block base 11) by an external force, and the first return spring 14 is compressed to contract by being pushed by the first tongue 12. At this time, the first locking structure 12a protruding outwards is not mutually abutted against the fixed block limiting piece 22 any more, so that the first lock tongue 12 is pushed back to the first position under the action of the spring restoring force of the first restoring spring 14 under the condition that the fixed block limiting piece 22 is not blocked, the user can pull the fixed block assembly 1 in a manner of holding and simultaneously lifting the grab handle device 3 upwards, so that the fixed block assembly 1 slides upwards synchronously along the slotting direction of the fixed block slot 21a until the fixed block assembly 1 slides out of the heat insulation block assembly 2, and the whole disassembly process is completed.

In a second aspect of the invention, there is provided an air fryer comprising the detachable handle means as described above.

Referring to fig. 7 and 8, fig. 7 is a perspective view illustrating an air fryer at a bottom angle when the air fryer is not loaded with a fryer vat according to an embodiment of the invention, and fig. 8 is a cross-sectional view illustrating an air fryer according to an embodiment of the invention.

Specifically, the lower housing 4 of the air fryer is generally in the shape of an upwardly open basin with a fryer opening 41 open on the front side. The motor cover 5 is arranged at the opening above the lower shell 4 in a buckling manner, and a motor cover lock hole 51 is formed on the lower surface of the front side of the motor cover 5 and is used for matching with the grab handle component 3 to longitudinally slide at the opening. The fryer vat 6 is adapted to be loaded with food material for cooking and heating, is generally in the form of an open-ended drawer or basin, and is received within the lower housing 4 and is laterally slidable to be withdrawn outwardly from the front of the vat opening 41 or pushed inwardly into the lower housing 4. A detachable grip means is provided on the front outer surface of the fryer vat 6 and provides a support surface for the user when gripping by the grip assembly 3. And, the second lock tongue 32 is arranged inside the handle assembly 3, so that the handle assembly 3 provides a holding support surface for a user and can realize the locking function of the frying barrel 6.

Preferably, two handle pivot holes 31d are provided on the inner surface of the handle base 31 to support the second latch 32 to rotate, and a through handle lock hole 11c is provided on the top surface of the handle base 31. In addition, the second lock tongue 32 accommodated in the grab handle assembly 3 is a generally upturned tongue body, and comprises a second locking structure 32a for locking the frying barrel 6, and second rotating shafts 33 protruding outwards to form a cylinder are respectively arranged at two sides of the second lock tongue 32, and the second rotating shafts 33 are rotatably installed in the grab handle rotating shaft holes 31d, so that the second lock tongue 32 can rotate clockwise and anticlockwise around the second rotating shafts 33 to realize locking and unlocking functions. The highest position is defined as a locking position when the second locking structure 32a is located at the highest position to which the second locking bolt 32 rotates, and correspondingly, the lowest position is defined as a retracted position when the second locking structure 32a is located at the lowest position to which the second locking bolt 32 rotates.

Further, when the fryer vat 6 is pushed into the lower housing 4 from the vat opening 41, the opening of the handle lock hole 11c and the motor housing lock hole 51 communicate with each other, i.e., the projection of the handle lock hole 11c in the longitudinal direction overlaps with the projection of the motor housing lock hole 51 in the longitudinal direction. The second locking structure 32a is longitudinally movable between the aforementioned locking position and the retracted position in a state where the locking holes are in communication with each other.

Specifically, in the process that the second locking structure 32a is driven to slide upwards from the retracted position to the locking position by the counterclockwise rotation of the second lock tongue 32, the second locking structure 32a first slides longitudinally upwards out of the handle lock hole 11c, and then continues to slide longitudinally upwards until the second locking structure is inserted into the motor housing lock hole 51. At this time, the second locking structure 32a simultaneously and transversely defines the relative positions of the motor cover locking hole 51 and the handle locking hole 11c, so that the integral structure where the handle locking hole 11c is located (i.e., the integral structure formed by the fixed block assembly 1, the heat insulation block assembly 2, the handle assembly 3 and the frying bucket 6 together) cannot transversely slide relative to the integral structure where the motor cover locking hole 51 is located (i.e., the motor cover 5), and the motor cover 5 and the lower shell 4 are combined with each other, so that the frying bucket 6 cannot transversely slide relative to the lower shell 4, thereby realizing the function of safely locking the frying bucket 6.

Specifically, in the process that the second locking structure 32a is driven to move downward from the locking position to the retracted position by the rotation of the second lock tongue 32, the second locking structure 32a slides out of the motor cover lock hole 51 first, and then continues to slide downward until the handle lock hole 11c is retracted. At this time, the second locking structure 32a does not limit the relative positions of the motor cover locking hole 51 and the handle locking hole 11c laterally any more, so that the whole body where the handle locking hole 11c is located (that is, the whole structure formed by the fixing block assembly 1, the heat insulation block assembly 2, the handle assembly 3 and the frying pan 6 together) can recover the capability of sliding laterally relative to the whole body where the motor cover locking hole 51 is located (that is, the motor cover 5), and the motor cover 5 and the lower housing 4 are combined with each other, so that the frying pan 6 can recover the capability of sliding laterally relative to the lower housing 4, and the transition operation from the safe locking state to the unlocking state of the frying pan 6 is realized.

Further, as shown in fig. 2 and 8, in order to implement the locking function of the frying vat 6 and simultaneously provide the second locking tongue 32 with the reset function, the locking mechanism of the frying vat 6 further comprises, in addition to the main components described above, a second reset spring 34 and a lower limit post 31b, and correspondingly, an upper limit post 32b is provided on the lower surface of the second locking tongue 32.

Specifically, the second return spring 34 is disposed between the second lock tongue 32 and the inner surface of the grip base 31, and in order to fix the second return spring 34 and prevent the second return spring 34 from loosening from the second lock tongue 32 and the grip base during movement, the upper and lower ends of the hollow spring tube of the second return spring 34 are respectively sleeved outside the lower limit post 31b and the upper limit post 32b, so that the second return spring 34 is clamped between the lower surface of the second lock tongue 32 and the inner surface of the grip base 31, and simultaneously, the second return spring 34 is further fixed and prevented from loosening by the combination of the hollow spring tube of the second return spring 34, the lower limit post 31b and the upper limit post 32b.

In the preferred embodiment, when the second lock tongue 32 is in a state of not receiving an external force, the second lock tongue 32 does not rotate clockwise about the second rotating shaft 33 due to the external force. The second lock tongue 32 is not pushed by external force, and the second return spring 34 can keep the second lock tongue 32 in the locking position only by the action of self spring pressing force. In the locking position, the longitudinally protruding second locking structure 32a laterally defines the relative positions of the motor housing locking hole 51 and the handle locking hole 11c, so that the fryer vat 6 cannot slide laterally relative to the lower housing 4, at which time the user cannot pull the vat 6 outwards due to the interference of the locking mechanism.

In the preferred embodiment, when the second locking bolt 32 is subjected to an external force, the second locking bolt 32 rotates clockwise about the second rotation shaft 33. Meanwhile, in the process of clockwise rotation of the second lock tongue 32 due to the external force, a downward force is applied to the top end of the second return spring 34 through the lower surface of the second lock tongue 32 to compress the second return spring 34. The second locking structure 32a will first be withdrawn from the motor housing lock hole 51 and then continue to move downward until the grip lock hole 11c is withdrawn until the second lock tongue 32 reaches the retracted position. In the retracted position, the second locking structure 32a does not protrude upwards to the plane bordered by the motor housing locking hole 51 and the handle locking hole 11c, so that the lateral movement of the fryer vat 6 with respect to the lower housing 4 is not restricted. At this point, the user may choose to pull or push the fryer vat 6 in as desired without interference from the locking mechanism. It should be noted that the second return spring 34 in this state is contracted by being pressed by an external force, and elastic potential energy is accumulated together during the contraction of the spring.

In the preferred embodiment, when the user completes the picking and placing of the fryer vat 6 and stops applying the pushing force to the tongue to rotate in the clockwise direction, the second return spring 34 tends to extend upward and simultaneously release the elastic potential energy as it is no longer compressed by the external force. In the process of extending upwards, the upper end of the second return spring 34 applies an upward force to the lower surface of the second lock tongue 32, so as to push the second lock tongue 32 to move from the retracted position to the locking position in a counterclockwise rotation mode, and thus the second locking structure 32a is driven to move upwards. The second locking structure 32a protrudes from the handle lock hole 11c first and is inserted into the motor housing lock hole 51. In the locking position, the longitudinally protruding second locking structure 32a laterally defines the relative positions of the motor housing locking hole 51 and the handle locking hole 11c, so that the fryer vat 6 cannot slide laterally relative to the lower housing 4, at which time the user cannot pull the vat 6 outwards due to the interference of the locking mechanism.

Further, in order to facilitate the user to unlock simply and quickly in the process of pulling out the frying vat 6, the air fryer of the embodiment of the invention is further provided with an unlocking switch 35 in the handle assembly 3, so as to facilitate the user to control the rotation of the second lock tongue 32 to unlock. Correspondingly, a switch through hole 31a for pressing the unlocking switch 35 by a user is also provided on the top surface of the grip base 31, and when the grip assembly 3 is assembled, the unlocking switch 35 protrudes from the switch through hole 31a in the longitudinal height direction. In addition, the opening shape of the opening and closing through hole 31a is also matched with the longitudinal projection shape of the unlocking switch 35, so that the unlocking switch 35 can slide longitudinally relative to the grab handle assembly 3.

Specifically, when the second lock tongue 32 is in the locked position, the user pushes the unlocking switch 35 downward to push the second lock tongue 32 together with the handle assembly 3, and the second lock tongue 32 rotates clockwise about the second rotation shaft 33, so that the second return spring 34 is compressed while the second lock tongue 32 rotates in the direction from the locked position to the retracted position. At this time, the second locking structure 32a is withdrawn from the motor cover locking hole 51 and retracted into the handle locking hole 11c, so that the lateral movement of the fryer vat 6 with respect to the lower housing 4 is not restricted. At this point, the user may choose to pull or push the fryer vat 6 in as desired without interference from the locking mechanism.

Specifically, when the second lock tongue 32 is not in the locking position (for example, in the retracted position) and the user releases the external force applied to the unlocking switch 35, the second return spring 34 will push the second lock tongue 32 to rotate counterclockwise due to the upward spring restoring force generated by the elastic potential energy accumulated by compression until the second locking structure 32a protrudes from the grip lock hole 11c and is inserted into the motor cover lock hole 51. Simultaneously, the second lock tongue 32 is pushed by the second return spring 34 to synchronously push the unlocking switch 35 to longitudinally slide upwards until the unlocking switch 35 reaches the highest point of the stroke, and at this time, the user cannot pull out the frying vat 6 due to the interference of the second lock tongue 32.

In a preferred embodiment, the front side surface of the fryer vat 6 of an embodiment of the invention is provided with an insulation block assembly 2 having a thickness to prevent excessive cooking temperatures in the air fryer from being transferred to the outside surface in front of the vat 6 to reduce the risk of scalding users in connection with the description of the insulation block assembly 2 in the detachable grip arrangement described above. Correspondingly, the handle assembly 3 is disposed on the outside surface of the insulation block assembly 2, and after the fryer vat 6 is pushed into the air fryer, the insulation block front cover 23 serves as the outside panel of the insulation block assembly 2, and the surface thereof is substantially co-joined with the surface of the outer housing 7 of the air fryer to form the outside surface of the air fryer as a whole. In other words, when the fryer vat 6 is pushed into the lower housing 4 so that the handle lock hole 11c communicates with the motor housing lock hole 51, the outer side surface of the insulation block front cover 23 is substantially in the same plane as the outer surface of the outer housing 7. In addition, the handle assembly 3 further comprises a handle front cover 36 disposed outside the handle base 31, and the handle front cover 36 can cover the second lock tongue 32 on the outer side, and make the handle assembly 3 more beautiful.

Further, referring to fig. 7 and 8, the present invention further includes a heating assembly 8 and an outer housing 7. Wherein, shell body 7 detains and locates motor cover 5 top, locates motor cover 5 between the two with lower casing 4 jointly. Further, the heating assembly 8 includes a hot air fan 82, a heating pipe 83, and a motor 81. Wherein, the hot air fan 82 is arranged below the motor cover 5, the heating pipe 83 is arranged below the hot air fan 82, the motor 81 is arranged above the motor cover 5, and the motor cover 5 is arranged between the motor 81 and the hot air fan 82 in a sealing way. During the operation of the air fryer, the motor 81 may be used to drive the hot air fan 82 to rotate, and the hot air fan 82 accelerates the air flowing in the air fryer through rotation and flows to the heating pipe 83, and the accelerated air is heated by the heating pipe 83 and then is blown down to the food material placed in the fryer vat 6 to achieve the purpose of air cooking.

Thus, the removable fryer assembly for an air fryer of the invention, through the cooperation of the fixed block assembly 1 with the insulation block assembly 2 and the handle assembly 3, allows the handle device to be removably disassembled while achieving the basic push-pull and transfer fryer functions, reducing the external lateral dimensions of the air fryer.

The detachable frying barrel assembly for the air fryer of the invention simplifies the disassembly and assembly flow of the grab handle device by arranging the first lock tongue 12 and matching with the first return spring 14 and the unlocking hole 23a, thereby facilitating the operation of users.

The detachable fryer assembly for the air fryer of the invention ensures the durability under long-term use through the sliding design of the fixed block convex wings 11a and the fixed block slot 21a which are matched with each other.
