The air fryer generally comprises a main machine with an upper opening, and a flip cover, wherein an inner pot component arranged in the opening of the main machine is rotatably arranged on one side of the opening of the main machine, a hot air component is arranged in the flip cover, and a lower heating disc component capable of heating the inner pot component is arranged on the lower part of the main machine. When the inner pot component is used for placing the prepared food materials, the flip cover is covered, and the cooking program is started, the lower heating disc component can be used for frying, baking and the like the food materials in the inner pot component; the hot air component in the flip cover generates high-temperature hot air, and the high-temperature hot air blows over the food materials downwards, so that the effects of similar baking and oil-free dry frying are formed for the food materials, the fried food materials can have the cooking taste and effect, and the adverse effect of the fried food materials on the human health can be avoided. Of course, the lower heating plate assembly and the hot air assembly can be started to cook food materials at the same time.

However, the prior air fryer has the following technical defects: firstly, when a user opens the flip cover, external impurities, foreign matters and the like easily fall into the inner pot component, so that the cleanness and the sanitation of food materials are influenced, and the impurities falling into the inner pot component are easily burnt and caked at the bottom of the inner pot to cause difficulty in cleaning once adhered to the bottom of the inner pot. Secondly, because a connecting circuit needs to be arranged between the hot air component and the host, the arrangement of the hot air component in the frequently rotating flip cover can cause the difficulty of the arrangement of the connecting circuit and even the phenomenon of breakage.

To this end, one has a lateral opening in one side of the main unit and the inner pot assembly is placed in the lateral opening. Therefore, when cooking, the inner pot assembly placed with the food materials can enter the lateral opening from the side; when the cooking is finished, the inner pot component is pulled out only from the side. This design can greatly make things convenient for connecting circuit's setting between hot-blast subassembly and the host computer to can avoid impurity, foreign matter to fall into in the pot subassembly from the top effectively, thereby convenient the washing. However, the following drawbacks still exist: for a clamshell air fryer, the lower heater tray assembly is positioned against the bottom wall of the inner pan assembly to facilitate improved heat transfer efficiency. And to the air fryer of side direction pull formula, if lower heating pan subassembly pastes the diapire setting of leaning on interior pot subassembly, then interior pot subassembly when pull business turn over side direction opening, the diapire of interior pot subassembly can produce the friction with lower heating pan subassembly, damage the surface coating of lower heating pan subassembly and interior pot subassembly easily, when even the height of heating pan subassembly has the error down, can cause interior pot subassembly to get into side direction open-ended difficulty, perhaps can make and form certain gap between the diapire of interior pot subassembly and the lower heating pan subassembly to heat transfer efficiency between heating pan subassembly and the interior pot subassembly is down seriously influenced.

That is, the utility model not only has the advantages of high heat transfer efficiency of the flip-type air fryer and difficult damage caused by friction, but also has the characteristics of cleanness, sanitation and convenient use of the pull-type air fryer.

Preferably, the lower heating plate is arranged on the main machine in a lifting mode, a return spring is arranged on the lower side of the lower heating plate, and when the inner pot assembly is in the working state, the return spring enables the lower heating plate to ascend.

It will be appreciated that the return spring provided on the underside of the lower heating plate may provide an upward spring force to the lower heating plate, thereby automatically springing the lower heating plate upward against the underside of the inner pot assembly. That is to say, the lifting control mechanism only needs to control the lower heating plate to overcome the elastic force of the return spring and move downwards, thereby greatly simplifying the lifting control mechanism and facilitating the reliable control of the action of the lower heating plate.

Preferably, the inner pot assembly comprises a guide rail bracket in sliding connection with the lateral opening, and the inner pot is arranged on the guide rail bracket, and when the inner pot assembly is in a moving state, the guide rail bracket presses against the upper side of the heating plate.

The guide rail bracket is in sliding connection with the lateral opening, so that the inner pot component can smoothly enter and exit the lateral opening like a drawer, and the operation and the control are convenient.

Particularly, only when the inner pot component is in a moving state entering the lateral opening, the guide rail bracket presses the upper side of the lower heating plate, so that the lower heating plate can move downwards against the elastic force of the return spring; meanwhile, only when the inner pot component is in a moving state of moving out of the lateral opening, the guide rail bracket also pushes the upper side of the lower heating plate, so that the lower heating plate can move downwards against the elastic force of the return spring.

That is to say, when interior pot subassembly is in business turn over side direction open-ended moving state, the guide rail bracket all can support and press down heating plate upside and make lower heating plate move down to avoid lower heating plate and the interior pot diapire in the moving to take place the friction, block even. When the inner pot component is in a working state, the guide rail bracket does not press the lower heating plate any more, and at the moment, the lower heating plate automatically bounces upwards under the elastic action of the return spring to reset, so that the lower heating plate is tightly attached to the bottom wall of the inner pot.

Preferably, the main frame comprises a main body at the upper part and a base support connected to the lower end of the main body, and the lower heating plate assembly comprises a fixing support arranged on the lower heating plate and connected with the base support.

The fixing bracket connected with the base bracket is arranged on the lower heating plate, so that the upward moving distance and position of the lower heating plate can be conveniently limited, and the lower heating plate component can form a complete independent component to be assembled with the base bracket.

Preferably, an inner guide pipe and an outer guide pipe which are mutually inserted are arranged between the lower heating plate and the lower part of the main machine, and a return spring is sleeved on the outer guide pipe.

The inner guide pipe and the outer guide pipe which are mutually inserted can lead the lower heating plate and the lower part of the main machine to form good moving guide and positioning, and the phenomenon that the lower heating plate is inclined or even blocked when moving up and down is avoided.

In addition, outer pipe and interior pipe are the tubular structure, that is to say, it can adopt less wall thickness, under the prerequisite of guaranteeing its self intensity, be favorable to reducing even eliminate down heating plate and base support surface and set up flaw such as the shrink mark appears in interior pipe and outer pipe.

Preferably, the lifting control mechanism comprises a pressing strip arranged on the lower side edge of the guide rail bracket, a pressing chamfer is arranged on the front side of the pressing strip, a pressing protrusion is arranged on the side edge of the lower heating plate, a front matching chamfer is arranged on one side, close to the side opening, of the pressing protrusion, and when the inner pot assembly enters the side opening, the pressing chamfer is matched with the chamfer before being extruded and the lower heating plate moves downwards.

When the inner pot component moves inwards to enter the lateral opening, the pressing chamfer arranged at the front side of the pressing strip at the lower side edge of the guide rail bracket extrudes the front matching chamfer on the pressing protrusion at the side edge of the lower heating plate, so that a downward acting component force is formed on the lower heating plate, and the lower heating plate is driven to move downwards; when the inner pot component is in a working state, the pressing strip and the abutting protrusion are separated in a staggered mode, and the lower heating plate is driven by the return spring to move upwards and abut against the bottom wall of the inner pot.

In addition, the pressing strip has the effect similar to a reinforcing rib relative to the guide rail bracket, namely, the pressing strip arranged on the lower side edge of the guide rail bracket can drive the lower heating plate to move downwards and can also form a reinforcing effect on the guide rail bracket.

Preferably, the rear side of the pressing strip is provided with a positioning chamfer, one side, far away from the lateral opening, of the pressing protrusion is provided with a rear matching chamfer, and when the inner pot assembly is in a working state, the positioning chamfer is matched with the rear matching chamfer in a supporting mode.

According to the utility model, the positioning chamfer is arranged at the rear side of the pressing strip, and the rear matching chamfer is arranged at one side of the pressing bulge, which is far away from the lateral opening. Therefore, when the inner pot component is in a working state, the positioning chamfer is matched with the chamfer after being abutted, so that the inner pot component is reliably positioned.

Particularly, when the inner pot component is pulled and moved outwards from the inside of the lateral opening, the positioning chamfer arranged at the rear side of the pressing strip at the lower side edge of the guide rail bracket extrudes the rear matching chamfer at the side edge of the lower heating plate which is pressed against the protrusion, so that a downward acting component force is formed on the lower heating plate, and the lower heating plate is driven to move downwards. That is to say, the inner pot component at this moment also has the effect of driving the lower heating plate downwards, so that the friction between the bottom wall of the inner pot and the lower heating plate can be thoroughly avoided.

Preferably, the lateral length of the pressing chamfer is 2.5-4.2 times of the lateral length of the positioning chamfer.

It can be understood that when the transverse length of the pressing chamfer is longer, the pressing chamfer is convenient to downwardly press the heating plate, so that the inner pot assembly can easily enter the lateral opening; on the contrary, when the transverse length of the positioning chamfer is shorter, the positioning chamfer is favorable for reliably positioning the inner pot component in the lateral opening, and the condition that the inner pot component slides outwards when in work due to misoperation of a user is avoided.

According to the utility model, the ratio of the transverse length of the pressing chamfer to the transverse length of the positioning chamfer is reasonably set, so that the inner pot component can conveniently enter the lateral opening, the reliable positioning of the inner pot component in the lateral opening is facilitated, and the inner pot component can be ensured to be pulled out from the lateral opening.

When the transverse length of the pressing chamfer is less than 2.5 times of the transverse length of the positioning chamfer, the inner pot component is difficult to enter the lateral opening or is difficult to pull out from the lateral opening; when the transverse length of the abutting chamfer is 4.2 times greater than that of the positioning chamfer, the inner pot component is easily pulled out from the side opening, so that the reliability of the positioning of the inner pot component in the side opening is reduced, or the inner pot component is extruded downwards when entering the side opening, the path of the heating disc is overlong, and the transverse size of the host is increased.

Preferably, a transition fillet is arranged at the front end of the front matching chamfer.

When the inner pot assembly enters the lateral opening, the pressing chamfer arranged at the front side of the pressing strip on the lower side edge of the guide rail bracket can firstly press against the transition fillet, then the pressing chamfer is glidingly moved to the front matching chamfer, and then the lower heating plate is pressed to form a downward acting component force on the lower heating plate so as to drive the lower heating plate to move downwards. Because the front end of the front matching chamfer is provided with the transition fillet, the sharp corner of the front end of the front matching chamfer can be passivated, and the length of the whole front matching chamfer is shortened, so that the strength of the front end of the front matching chamfer is favorably improved, and the abutting chamfer on the front side of the pressing strip can be smoothly slid onto the front matching chamfer.

Preferably, a round hole is formed in the middle of the fixing support, and the lower heating plate comprises a protruding disc which penetrates through the round hole upwards.

Because be equipped with the round hole in the middle of the fixed bolster to make it be the annular, and lower heating plate is including the protruding disc that upwards passes the round hole, on the one hand, can make lower heating plate reliably spacing in direction of height and horizontal direction, on the other hand, can furthest reduce the area of contact of fixed bolster and lower heating plate, avoid on the heat of lower heating plate transmits the base support of host computer through the fixed bolster.

Detailed Description

The utility model is further described with reference to the following detailed description and accompanying drawings.

As shown in fig. 1 and 2, the conveniently cleaned air-frying machine comprises a main machine 1 with a lateral opening 11 arranged on one side, an inner pot component 2 comprising an inner pot 21 is arranged in the lateral opening, a lower heating plate component 3 comprising a lower heating plate 31 is arranged on the lower portion of the lateral opening, and the inner pot component comprises a moving state of entering and exiting the lateral opening and a working state of positioning in the lateral opening.

Because set up the side direction opening in host computer one side to can effectively avoid impurity, foreign matter to drop in the pot, and the washing of pot subassembly in the back of facilitating the use, and can keep eating the sanitation and hygiene of material.

When the food materials need to be cooked, the processed food materials can be placed in the inner pot, then the inner pot assembly is placed into the lateral opening, and then the corresponding cooking program is started, so that the food materials in the inner pot can be correspondingly 'air-fried'.

In order to ensure that the bottom wall of an inner pot in the inner pot component in the working state is tightly attached to the lower heating plate, so that the heating efficiency is improved as much as possible, and meanwhile, the lower heating plate is prevented from rubbing with the bottom wall of the inner pot when the inner pot component enters and exits from the lateral opening, the lower heating plate can be arranged in a lifting mode, and a lifting control mechanism is arranged between the inner pot component and the lower heating plate component.

Therefore, when the inner pot is in a moving state of the inlet and outlet side openings, the lifting control mechanism enables the lower heating plate to descend to be separated from the bottom of the inner pot, so that the bottom of the inner pot and the lower heating plate can be effectively prevented from being rubbed, and the service lives of the inner pot and the lower heating plate can be prolonged; when the inner pot component moves in place in the lateral opening and is in a working state, the lifting control mechanism enables the lower heating plate to rise to be attached to the bottom of the inner pot, and therefore heat transfer efficiency between the lower heating plate and the inner pot is guaranteed.

That is, the utility model not only has the advantages of high heat transfer efficiency of the flip-type air fryer and difficult damage caused by friction, but also has the characteristics of cleanness, sanitation and convenient use of the pull-type air fryer.

Preferably, as shown in fig. 1, 2 and 3, the lower heating plate is arranged at the bottom of the main machine in a lifting manner, and a return spring 4 is arranged at the lower side of the lower heating plate and abuts against the lower heating plate, so as to form an upward elastic force on the lower heating plate. When the inner pot is in a moving state of entering and exiting the lateral opening, the lifting control mechanism enables the lower heating plate to overcome the elastic force of the return spring to descend, and then the lower heating plate is separated from the bottom of the inner pot. When the inner pot component is in a working state, the return spring enables the lower heating plate to rise.

That is, the return spring constitutes a part of the elevation control mechanism, and the elevation control mechanism only generates a downward acting force on the lower heating plate when the inner pot assembly enters and exits the lateral opening, thereby controlling the lower heating plate to move downward against the elastic force of the return spring. When the inner pot component moves in place and enters a working state, the lifting control mechanism eliminates the acting force on the lower heating plate, and only the return spring forms upward elastic force on the lower heating plate at the moment, so that the lifting control mechanism can be greatly simplified, and the action of the lower heating plate can be reliably controlled conveniently.

Further, the inner pot assembly comprises a guide rail bracket 22, the guide rail bracket comprises a control panel 221 capable of blocking a lateral opening, a left guide rail 222 and a right guide rail 222 which are arranged on the lower portion of the inner side of the control panel and are in sliding connection with the lateral opening, the inner ends of the two guide rails are connected into a U shape through a transverse connecting rod 223, the connecting rods are arranged in a lifting mode, therefore, a containing space for containing the inner pot is formed among the control panel, the connecting rod, the left guide rail and the right guide rail, the guide rail bracket is connected into a ring shape, and the strength of the guide rails can be improved.

In addition, the inner pot is arranged in the accommodating space of the guide rail bracket. When the inner pot component is in a moving state, the whole guide rail bracket can be communicated with the inner pot and smoothly enter and exit the lateral opening like a drawer only by pushing and pulling the control plate, so that the control is convenient. Meanwhile, the left and right guide rails of the guide rail bracket are pressed downwards to the left and right sides of the lower heating plate, so that the lower heating plate can move downwards against the elastic force of the return spring.

That is to say, only when interior pot subassembly is in the moving state of business turn over side direction opening, the guide rail bracket just can support downwards and press down heating plate to avoid lower heating plate and the interior pot diapire in the moving to take place the friction, block even. When the inner pot component is in a working state, the guide rail in the guide rail bracket does not support and press the lower heating plate any more, and at the moment, the lower heating plate automatically bounces upwards under the elastic action of the return spring to reset, so that the lower heating plate is tightly attached to the bottom wall of the inner pot.

Further, the main body includes an upper main body 12, a head 14 disposed on the main body, and a base support 13 connected to a lower end of the main body, and the lower heating plate assembly includes a fixing support 32 disposed on the lower heating plate and connected to the base support.

Because the lower heating plate is provided with the return spring, the lower heating plate can be limited by the fixing bracket when moving upwards and can be accurately positioned. In addition, when the lower heating disc component is assembled as a whole independent component with the base support to form a component, the lower heating disc component is convenient to be connected with the upper main body for assembly.

In order to ensure the stable lifting of the lower heating plate, as shown in fig. 4, an outer guide pipe 131 is arranged on the upper side of the base support, an inner guide pipe 311 is arranged on the lower side of the lower heating plate, and the inner guide pipe is movably inserted into the outer guide pipe, so that good moving guide and positioning are formed between the lower heating plate and the base support, and the lower heating plate is prevented from being deflected or even jammed when moving up and down.

In addition, we can establish reset spring cover on outer pipe, and outer pipe this moment plays the positioning action to reset spring, avoids reset spring because of the bending displacement of compression.

Specifically, as shown in fig. 5 and 6, the lifting control mechanism includes a pressing strip 224 disposed on the lower side of the guide rail in the guide rail bracket, a pressing chamfer 225 is disposed on the front side of the pressing strip, correspondingly, a strip-shaped pressing protrusion 312 is disposed on the side of the lower heating plate, and a front matching chamfer 313 is disposed on the side of the pressing protrusion close to the lateral opening.

When the inner pot component enters the lateral opening, the pressing chamfer is matched with the chamfer before being extruded, and the lower heating plate moves downwards.

When the inner pot component moves inwards to enter the lateral opening, the pressing chamfer arranged at the front side of the pressing strip at the lower side edge of the guide rail bracket extrudes the front matching chamfer on the pressing protrusion at the side edge of the lower heating plate, so that a downward acting component force is formed on the lower heating plate, and the lower heating plate is driven to move downwards; when the inner pot component is in a working state, the pressing strip and the abutting protrusion are separated in a staggered mode, and the lower heating plate is driven by the return spring to move upwards and abut against the bottom wall of the inner pot.

It should be noted that, the side of the inner pan assembly facing the lateral opening when entering the lateral opening is referred to as the front side, and the opposite side is referred to as the rear side. In addition, because the left side and the right side of the guide rail bracket are both provided with the pressing strips, the left side and the right side of the lower heating plate are both provided with the strip-shaped pressing bulges so as to ensure that the two sides of the lower heating plate are uniformly stressed. The pressing strip arranged on the lower side edge of the guide rail bracket can drive the lower heating plate to move downwards and can also strengthen the guide rail bracket.

Further, we can provide a positioning chamfer 226 on the rear side of the bead, and a corresponding rear mating chamfer 314 on the side of the pressing projection remote from the lateral opening. Therefore, when the inner pot component moves inwards to the proper position and is in a working state, the positioning chamfer angle is matched with the chamfer angle after being abutted, so that the inner pot component is reliably positioned, and the inner pot component is prevented from easily sliding outwards from the inside of the lateral opening.

Of course, when the inner pan assembly is pulled and moved outwards from the inside of the lateral opening, the positioning chamfer arranged at the rear side of the guide rail bracket pressing strip can extrude the rear matching chamfer on the pressing protrusion of the side edge of the lower heating plate, so that a downward acting component force is formed on the lower heating plate, and the lower heating plate is driven to move downwards. That is to say, interior pot subassembly at this moment also has the effect of drive lower heating plate downwards to can avoid effectively interior pot to produce the friction between diapire and the lower heating plate when business turn over side opening.

Preferably, we can make the lateral length of the pressing chamfer 2.5-4.2 times the lateral length of the positioning chamfer.

Through rationally setting up the ratio of the transverse length of the abutting chamfer angle and the transverse length of the positioning chamfer angle, on one hand, the pot component can conveniently enter the lateral opening, on the other hand, the reliable positioning of the pot component in the lateral opening is facilitated, and meanwhile, the pot component can be ensured to be pulled out from the lateral opening.

In addition, transition fillets 316 may be provided at the forward ends of the forward mating fillets. When the inner pot assembly enters the lateral opening, the pressing chamfer arranged at the front side of the pressing strip on the lower side edge of the guide rail bracket can firstly press against the transition fillet, then the pressing chamfer is glidingly moved to the front matching chamfer, and then the lower heating plate is pressed to form a downward acting component force on the lower heating plate so as to drive the lower heating plate to move downwards. The transition fillet can "passivate" the closed angle of preceding cooperation chamfer front end to shorten the length of whole preceding cooperation chamfer, on the one hand be favorable to promoting the intensity of preceding cooperation chamfer front end, on the other hand ensure that the support of layering front side presses the chamfer and can smoothly slide to preceding cooperation chamfer on.

In order to facilitate the connection of the fixing support and the lower heating plate, a round hole 321 can be formed in the middle of the fixing support, and the lower heating plate comprises a protruding disc 315 which penetrates through the round hole upwards, so that the fixing support can reliably limit the lower heating plate in the height direction and the horizontal direction.

In addition, the inner catheter and the outer catheter can be arranged at four corners of the fixed bracket. That is to say, the four corners of the fixed bracket are respectively provided with the inner guide pipe, the outer guide pipe and the corresponding return springs, so that the stability of the lower heating plate during lifting can be improved to the maximum extent, and the clamping stagnation phenomenon is avoided.

Of course, the raised circular disc should be higher than the fixed bracket to ensure that only the raised circular disc generating heat in the lower heating plate is connected with the bottom wall of the inner pot when the inner pot assembly is in the working state, and a gap is formed between the fixed bracket and the bottom wall of the inner pot at the moment, so that the heat transferred to the fixed bracket can be reduced to the maximum extent.

It will be understood that various changes and modifications other than those described in the preferred embodiments described above may be made by those skilled in the art without departing from the spirit of the utility model, which is defined in the appended claims.
