Description

Technical Field

[0001] This application relates to the field of small household appliances, and particularly to an air fryer. Background Art

[0002] In daily life, people increasingly use air fryers to cook and heat food. Usually, the food is placed in the cooking cavity, and hot air is transmitted into the cooking cavity through the hot air component to heat the food placed in the cooking cavity. If the hot air cannot be discharged from the cooking cavity all the time, the continuously increasing hot air will keep blowing on the food, resulting in the food becoming dry and firewood-like. At the same time, during the process of heating the food with hot air, a large amount of water vapor will be generated. If the water vapor accumulates in the cooking cavity and cannot be discharged to the outside in time along with the hot air, when the cooking cavity is opened after cooking, the pressure inside the cooking cavity will be relatively high due to the accumulation of a large amount of water vapor. A large amount of water vapor will gush out when the cooking cavity is opened. If the user operates improperly, the gushing water vapor is extremely likely to scald the user's hands and face.

[0003] In the prior art, in order to discharge the hot air in the cooking cavity to the outside in time, the cooking cavity and the outside are usually connected through a pipeline to achieve the guiding effect on the hot air. For example, in the Chinese utility model patent CN219613676U, the air outlet component includes an air inlet pipe, a steam-containing cavity and a guide pipe that are connected in sequence. The air inlet pipe is connected to the cooking cavity, and the guide pipe is connected to the outside. In this way, the steam and hot air in the cooking cavity can be discharged by using the air outlet component to avoid the situation that too much steam and hot air accumulate in the cooking cavity, resulting in poor food taste or excessive pressure in the cooking cavity, causing unsafe use.

[0004] However, the method of directly discharging the steam and hot air in the cooking cavity through the air outlet component can discharge the steam and hot air in the cooking cavity in time, but during the discharge process, since no cooling treatment is performed on the steam and hot air, the temperature of the steam and hot air discharged from the air outlet component is still relatively high. If the air outlet component of the air fryer is set close to the wall, the high-temperature steam and hot air will damage the wall; or when the user checks the cooking situation of the air fryer, the high-temperature steam and hot air will directly scald the user.

[0005] For some air fryers, the lid includes a glass panel, and the glass panel is directly covered on the pot body. In order to enable the steam and hot air in the cooking cavity to be discharged to the outside, ventilation holes are provided on the glass panel, and the ventilation holes communicate the cooking cavity and the outside. In this way, when a certain amount of hot air and steam accumulate in the cooking cavity, the hot air and steam will be discharged to the outside along the ventilation holes. As described above, directly discharging the hot air and steam to the outside will scald the user and affect the user's experience of using the air fryer.

[0006] In order to reduce the temperature of the discharged water vapor and hot air, in the prior art, such as the Chinese utility model patent CN215687021U, a first fan blade for generating cold air and a second fan blade for generating hot air are provided, the cold air enters the confluence cavity through the first confluence inlet, the hot air enters the confluence cavity through the second confluence inlet, the cold air and the hot air are mixed and cooled inside the confluence cavity and then discharged to the outside, and the water vapor will also be cooled as the hot air and the cold air are mixed and then discharged to the outside. In this way, the temperature of the discharged hot air and water vapor will be reduced, reducing the probability of scalding the user.

[0007] All the cold air generated by the first fan blade and all the hot air generated by the second fan blade enter the confluence chamber to mix. When the hot air meets a large amount of cold air in a short period of time, the temperature of the hot air will drop sharply, and the higher temperature water vapor carried by the hot air will liquefy to produce condensed water. The condensed water will adhere to the confluence chamber and cannot be discharged. Long-term accumulation will accumulate more condensed water, which is easy to breed bacteria inside the air fryer. Summary of the invention

[0008] The present application discloses an air fryer, which is based on the air fryer in the prior art. When hot air and cold air are mixed and discharged to the outside of the air fryer, if all the cold air and hot air are mixed in the heat dissipation cavity, condensed water will be generated and cannot be discharged, thereby affecting the user experience.

[0009] The present application discloses an air fryer, comprising a pot body and a cover body covered on the pot body, the cover body and the pot body enclosing a cooking cavity, the cover body being provided with a reflector cover and a main body, the reflector cover being provided with a hot air component for generating hot air on a side of the reflector cover facing the cooking cavity, a connecting cylinder being provided on a side of the reflector cover facing away from the cooking cavity, the connecting cylinder and the reflecting cover being cooperated to form a heat dissipation cavity, a heat dissipation fan being provided in the heat dissipation cavity for generating cold air, an air outlet being provided on a cylinder side wall of the connecting cylinder, a plurality of air dividing plates being provided on the cylinder side wall of the connecting cylinder, the air outlet being divided into a first air outlet and a second air outlet by the plurality of air dividing plates, a mixing channel being formed between the plurality of air dividing plates, the mixed gas in the mixing channel being discharged from the second air outlet, a third air outlet being provided on the reflector cover, the third air outlet being connected to the cooking cavity and the mixing channel, the hot air in the cooking cavity entering the mixing channel through the third air outlet and being mixed with the cold air in the heat dissipation cavity and discharged to the outside.

[0010] Several optional methods are also provided below, but they are not intended to be additional limitations on the above-mentioned overall solution, but are merely further supplements or preferences. Under the premise that there are no technical or logical contradictions, each optional method can be combined with the above-mentioned overall solution separately, and multiple optional methods can also be combined.

[0011] Further, the reflecting cover extends upwardly and convexly to form a cover side wall, and the third air outlet is arranged on the cover side wall, and the air distribution plate extends from the cylinder side wall towards the cover side wall.

[0012] Further, in order to enable the cold air in the heat dissipation cavity to quickly discharge to the outside from the first air outlet and the second air outlet.

[0013] A plurality of air outlets arranged at intervals are provided on the cylinder side wall, and a plurality of air distribution plates are arranged in at least one air outlet to divide the air outlet into the first air outlet and the second air outlet.

[0014] Further, to solve the technical problem of the air outlet efficiency.

[0015] The first air outlet is arranged on both sides of the second air outlet and is arranged circumferentially along the cylinder side wall of the connecting cylinder.

[0016] A connecting seat is arranged on the pot body, a connecting component is arranged on the cover body, the connecting component is hinged on the connecting seat, and the second air outlet is opened towards the hinged position.

[0017] An air distribution plate is arranged in the area where the second air outlet faces the third air outlet, and the air distribution plate is inclined.

[0018] Further, in order to enable the cold air and hot air in the heat dissipation cavity and the cooking cavity to quickly discharge to the outside.

[0019] The rotation directions of the hot air component and the heat dissipation fan include a forward rotation direction and a reverse rotation direction, and the air distribution plate is inclined along the forward rotation direction.

[0020] Further, to solve the technical problem that the cold air cannot smoothly discharge from the air outlet.

[0021] The first air outlet and the second air outlet have the same height.

[0022] Further, to solve the technical problem of the unfixed cold air flow path.

[0023] Further, the cylinder side wall includes a guiding wall, the guiding wall extends downwardly and outwardly, and the guiding wall is located above the first air outlet and the second air outlet.

[0024] An air fryer of the present application is provided with a first air outlet and a second air outlet on a connecting cylinder. A part of the cold air generated by a cooling fan enters a mixing channel together with the hot air from the cooking cavity. The cold air and the hot air are mixed in the mixing channel to form mixed air. The temperature of the mixed air is relatively low, and it is not easy to scald the user when it is discharged to the outside from the second air outlet. Thus, part of the cold air flows out from the first air outlet, and part of the cold air flows out from the second air outlet to be mixed with the hot air flowing out from the third air outlet for cooling, reducing the air volume of the cold air mixed with the hot air and preventing condensation water from being generated when the cold air and the hot air are mixed.

[0025] Further, in order to enable the cold air in the cooling cavity to be discharged to the outside from the first air outlet and also enter the second air outlet through the mixing channel for discharge.

[0026] The first air outlet includes a plurality of first sub-air outlets, and the plurality of first sub-air outlets are continuously arranged on the side wall of the cylinder. The second air outlet includes a plurality of second sub-air outlets, and the plurality of second sub-air outlets are continuously arranged on the side wall of the cylinder.

[0027] Further, in order to improve the stability of the cold air flowing in the cooling cavity.

[0028] The first air outlets are respectively arranged on both sides of the second air outlet, and the first air outlet and the second air outlet are arranged adjacent to each other. Because the first air outlet and the second air outlet are adjacent to each other, when the cold air passes through one of the first air outlet or the second air outlet, it can quickly pass through the other second air outlet or the first air outlet. In this way, the probability of the cold air generating turbulence in the cooling cavity can be reduced, and the stability of the cold air flowing in the cooling cavity can be enhanced.

[0029] Further, in order to improve the exchange rate between the cooling cavity and the outside.

[0030] The plurality of first sub-air outlets and the plurality of second sub-air outlets are continuously arranged along the circumference of the side wall of the cylinder. In order to enable the cold air to be evenly discharged to the outside from the first air outlet, the first air outlet is spaced and evenly arranged on the side wall of the connecting cylinder, and the air outlets cover the entire side wall of the connecting cylinder. In this way, when the cold air moves from the top of the connecting cylinder towards the side wall direction, the cold air at different circumferential positions can be discharged to the outside from the inside of the cooling cavity at basically the same moving distance and through basically the same time.

When a component is referred to as being "disposed on" another component, it may be directly disposed on the other component or there may be a central component at the same time.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an air fryer 100 includes a pot body 200 and a cover body 300 covering the pot body 200, the cover body 300 and the pot body 200 enclose a cooking cavity 400, a reflector 301 and a body 512 are arranged on the cover body 300, a hot air component 302 for generating hot air is arranged on the side of the reflector 301 facing the cooking cavity 400, a connecting tube 500 is arranged on the side of the reflector 301 away from the cooking cavity 400, the connecting tube 500 cooperates with the reflector 301 to form a heat dissipation cavity 501, a heat dissipation fan 502 is arranged in the heat dissipation cavity 501 for generating cold air, and a tube side wall 509 of the connecting tube 500 is arranged A first air outlet 505 and a second air outlet 506, a part of the cold air from the heat dissipation cavity 501 is discharged to the outside through the first air outlet 505, a tube side wall 509 of the connecting tube 500 is provided with an air distribution plate 504, a mixing channel 507 is formed between the plurality of air distribution plates 504, and the mixed gas in the mixing channel 507 is discharged from the second air outlet 506, and a third air outlet 303 is provided on the reflective cover 301, and the third air outlet 303 connects the cooking cavity 400 with the mixing channel 507, and the hot air in the cooking cavity 400 enters the mixing channel 507 through the third air outlet 303 and is mixed with another part of the cold air from the heat dissipation cavity 501 and discharged to the outside.

[0051] The setting of the air distribution plate 504 can play a role in diverting the cold air generated in the heat dissipation cavity 501, so that a part of the cold air flows out to the outside through the first air outlet 505, and the other part of the cold air enters the mixing channel 507 to be mixed with the hot air and then discharged to the outside through the second air outlet 506, which not only reduces the heat when the hot air is discharged but also reduces the generation of condensed water.

[0052] In this embodiment, the air fryer 100 includes a pot body 200 and a lid body 300. The lid body 300 is covered above the pot body 200, and a cooking cavity 400 for holding food is formed by enclosing between the lid body 300 and the pot body 200. A reflector 301 is provided on the lid body 300, the cooking cavity 400 is arranged below the reflector 301, and a hot air assembly 302 is arranged in the cooking cavity 400. The hot air assembly 302 includes a heating tube 307 and a hot air fan 304. A driving motor 309 and a heat dissipation fan 502 are arranged above the reflector 301. The lid body 300 and the pot body 200 can be hinged, and the lid body 300 can be reversed relative to the pot body 200 to open or close the cooking cavity 400; of course, the lid body 300 can also be directly covered on the pot body 200, and of course, the lid body 300 can also be covered on the pot body 200 by a coupling method.

[0053] The lid body 300 has a first position where it is mutually covered with the pot body 200, and a second position where the pot body 200 is in an open state after the lid body 300 is flipped or inserted relative to the pot body 200. Taking the pot body 200 and the lid body 300 being flipped together by a hinge device as an example, before cooking, the user flips the lid body 300 so that the lid body 300 is in the second position. At this time, the lid body 300 and the pot body 200 are in an open state, and the user puts the food into the cooking cavity 400. During cooking, the user flips the lid body 300 again so that the lid body 300 is in the first position. At this time, the lid body 300 and the pot body 200 are in a closed state.

[0054] The lid body 300 includes a main body 512, a head 308 and a connecting cylinder 500. The connecting cylinder 500 is connected between the main body 512 and the head 308. The connecting cylinder 500 plays a certain guiding role in the cold air generated by the heat dissipation fan 502, so that the cold air flows along the outer contour shape of the connecting cylinder 500. A first air outlet 505 and a second air outlet 506 are provided on the cylindrical side wall 509 of the connecting cylinder 500, and the heat dissipation cavity 501 and the outside are connected through the first air outlet 505 and the second air outlet 506. The heat dissipation cavity 501 and the cooking cavity 400 are connected to the outside through the first air outlet 505 and the second air outlet 506 provided on the cylindrical side wall 509 of the connecting cylinder 500 to perform corresponding exchanges of substances such as gases or liquids.

[0055] The connecting cylinder 500 is a hollow cylindrical structure. The cross-section of the connecting cylinder 500 can be circular, square, elliptical, or irregular in shape, and the specific shape is not limited. Preferably, the connecting cylinder is a cylindrical structure with a narrower upper part and a wider lower part as described in Figure 4 the above.

[0056] Under normal circumstances, when the driving motor 309 is arranged in the air fryer 100, during the operation of the driving motor 309, a large amount of heat will be generated inside the driving motor 309. If the heat generated inside the driving motor 309 cannot be discharged to the outside in time, the temperature of the driving motor 309 will continue to rise, and in severe cases, the driving motor 309 will stop working. Therefore, in order to reduce the temperature of the driving motor 309, a cooling fan 502 is arranged in the heat dissipation cavity 501, and a part of the cold air generated by the cooling fan 502 is used to reduce the heat of the driving motor 309. A part of the cold air generated by the cooling fan 502 is discharged to the outside through the first air outlet 505, and the other part of the cold air enters the mixing channel 507 and is discharged to the outside through the second air outlet 506.

[0057] Preferably, the cover body 300 and the pot body 200 are hermetically connected. After the hot air component 302 generates hot air, the pressure inside the cooking cavity 400 will gradually increase due to the hot air and the water vapor generated during cooking. Since only the third air outlet 303 is provided on the reflection cover 301 to connect the cooking cavity 400 and the mixing channel 507, the hot air will enter the mixing channel 507 through the third air outlet 303 and then be discharged outside the cooking cavity 400 to prevent the pressure inside the cooking cavity 400 from being too high.

[0058] The air distribution plate 504 is arranged on both sides of the second air outlet 506. The third air outlet 303 on the reflection cover 301 is arranged opposite to the second air outlet 506 on the connecting cylinder 500. The air distribution plate 504 will guide the hot air to enter the mixing channel 507 from the third air outlet 303 and be discharged to the outside. At this time, the function of the air distribution plate 504 can guide the hot air into the mixing channel 507 and play a guiding role in the flow path of the hot air.

[0059] When the air diversion plate 504 is provided, most of the hot air directly enters the mixing channel 507 in the heat dissipation cavity 501 through the third air outlet 303 and is discharged to the outside through the second air outlet 506; if there is no air diversion plate 504 between the first air outlet 505 and the second air outlet 506, most of the hot air will enter the interior of the heat dissipation cavity 501 after passing through the third air outlet 303. After the hot air enters the interior of the heat dissipation cavity 501 and comes into contact with the cold air, condensed water will be generated, which will cause the air fryer 100 to be difficult to clean and affect the user experience. In the mixing channel 507, all the hot air is mixed with part of the cold air, reducing the proportion of cold air mixed with the hot air and avoiding the situation where the water vapor in the hot air rapidly cools and liquefies to generate condensed water.

[0060] The number of air diversion plates 504 can be set to 2. The opposite sides of the two air diversion plates 504 form the mixing channel 507. By setting the two air diversion plates 504, part of the cold air is discharged to the outside through the first air outlet 505, and part of the cold air is mixed with the hot air discharged from the mixing channel 507 and the cooking cavity 400.

[0061] In order to prevent the cold air and hot air entering the mixing channel 507 from generating turbulence, at least one more air diversion plate 504 is added in the middle of the two air diversion plates 504. As a preferred solution, the number of air diversion plates 504 is set to 4. In this way, the cold air and hot air entering the mixing channel 507 can be divided into multiple air ducts, so that the cold air and hot air can be smoothly discharged to the outside through the mixing channel 507, preventing the cold air and hot air from swirling in the mixing channel 507.

[0062] The air diversion plate 504 can be a long plate-like structure or a cylindrical structure, as long as part of the cold air can enter the middle of the air diversion plate 504 and be mixed with the hot air.

[0063] The mixing channel 507 is provided with a certain length in the radial direction of the air fryer 100. When the cooling fan 502 rotates to generate cold air, the cold air will enter the mixing channel 507 in the radial direction of the air fryer 100; the hot air will enter the mixing channel 507 in the axial direction of the air fryer 100; the wind speed of the cold air is greater than that of the hot air. Therefore, the pressure in the mixing channel 507 is less than the pressure at the third air outlet 303, and the hot air will be sucked into the mixing channel 507. While accelerating the entry of the hot air into the mixing channel 507, it can also effectively prevent the hot air from entering the heat dissipation cavity 501.

[0064] Since a large amount of heat is generated during the high-speed operation of the drive motor 309, and part of the heat generated by the heating tube 307 in the hot air assembly 302 is also transferred to the drive motor 309 and the connecting cylinder 500. If the drive motor 309 and the connecting cylinder 500 cannot be cooled in time, the drive motor 309 will stop working due to too rapid temperature rise, or some components of the drive motor 309 will deform because they cannot withstand the high temperature, and the connecting cylinder 500 will also deform due to being in a high-temperature state for a long time. Therefore, a cooling fan 502 is provided in the air fryer 100 to cool the drive motor 309 and the connecting cylinder 500 with the cold air generated by the cooling fan 502. The cold air generated by the cooling fan 502 is used to cool the drive motor 309 and the connecting cylinder. Part of the cold air generated by the cooling fan 502 is discharged to the outside from the first air outlet 505; another part of the cold air generated by the cooling fan 502 will enter the mixing channel 507 together with the hot air discharged from the cooking cavity 400. The cold air and the hot air are mixed in the mixing channel 507 to form mixed air. The temperature of the mixed air is relatively low, and it is not easy to scald the user after being discharged to the outside from the second air outlet 506. At the same time, through the air dividing plate 504 for physical separation, it is possible to prevent the hot air from escaping from the mixing channel 507, and prevent the hot air from entering the area outside the mixing channel 507 of the cooling cavity 501 and mixing with a large amount of cold air and then rapidly cooling and liquefying to form condensed water; at the same time, only part of the cold air entering the mixing cavity can also prevent the temperature in the mixing channel 507 from dropping too fast and causing the generation of condensed water.

[0065] In an embodiment of the present application, the drive motor 309 is used to drive the rotation of the hot air fan 304 and the cooling fan 502, and the drive motor 309 is fixed on the connecting cylinder 500. In this way, the drive motor 309 is hoisted on the machine head 308, which can reduce the overall height of the drive motor 309, so as to achieve the effect of making the machine head 308 thinner.

[0066] The cover body 300 is sealed with the pot body 200 through the main body 512, so that the water vapor in the cooking cavity 400 cannot be discharged to the outside from the connection between the cover body 300 and the pot body 200, thereby ensuring that the hot air in the cooking cavity 400 can be discharged to the outside through the third air outlet 303.

[0067] In another embodiment of the present application, the connecting cylinder 500 further includes a top wall 508. The upper edge of the cylinder side wall 509 extends radially inward to form the top wall 508, and the driving motor 309 is installed on the top wall 508. The driving motor 309 is installed at the upper end of the connecting cylinder 500. Specifically, the lower end of the driving motor 309 can be installed at the upper end of the connecting cylinder 500, that is, the driving motor 309 is seated on the upper end of the connecting cylinder 500. It can also be that the upper end of the driving motor 309 is installed at the lower end of the connecting cylinder 500, that is, the driving motor 309 is hoisted on the connecting cylinder 500.

[0068] Appendix Figure 1 ~Appendix Figure 7 Only the air fryer 100 with a flip cover through a hinge device is shown. The connecting cylinder 500 is arranged in a cylindrical structure that is narrower at the top and wider at the bottom, and the first air outlets 505 are arranged adjacent to both sides of the second air outlet 506. The first air outlets 505 and the second air outlet 506 cover the cylinder side wall 509. Other embodiments are not shown in the form of drawings but are recorded in words, and all are within the protection scope of the present invention.

[0069] Furthermore, in order to enable the hot air to smoothly enter the mixing channel 507 from the cooking cavity 400.

[0070] The reflecting cover 301 extends upward to form a cover side wall. The reflecting cover 301 bulges upward along the height direction of the air fryer 100, so that a part of the reflecting cover coincides with a part of the connecting cylinder, reducing the space of the heat dissipation cavity 501. The cover side wall extends into the heat dissipation cavity 501, and a third air outlet 303 is provided on the cover side wall. The air distribution plate 504 extends from the cylinder side wall 509 towards the cover side wall.

[0071] The air distribution plate 504 can either start extending from the cylinder side wall 509 towards the cover side wall or start extending from the top wall of the connecting cylinder 500 towards the cover side wall, as long as the setting of the air distribution plate 504 can enable the hot air to smoothly enter the mixing channel 507 and be discharged from the second air outlet 506.

[0072] The air distribution plate 504 and the cover side wall can either be in close contact with each other or have a certain distance therebetween. The distance between the two should not be too large to prevent a large amount of hot air from overflowing from the mixing channel 507 and affecting the discharge efficiency of the hot air.

[0073] Furthermore, in order to enable the cold air in the heat dissipation cavity 501 to quickly be discharged to the outside from the first air outlets 505 and the second air outlets 506.

[0074] The first air outlet 505 includes a plurality of first sub-air outlets 513, and the plurality of first sub-air outlets 513 are continuously arranged on the barrel side wall 509. The second air outlet 506 includes a plurality of second sub-air outlets 514, and the plurality of second sub-air outlets 514 are continuously arranged on the barrel side wall 509.

[0075] Preferably, as Figure 8 shown, after the plurality of first sub-air outlets 513 are continuously arranged, the plurality of second sub-air outlets 514 are continuously arranged, or according to needs, a plurality of first sub-air outlets 513 are connected after the plurality of second sub-air outlets 514, and so on. The first air outlet 505 and the second air outlet 506 are staggered. The plurality of second sub-air outlets 514 can be arranged at a relatively short distance from the plurality of first sub-air outlets 513, or the plurality of second sub-air outlets 514 can be arranged at a relatively long distance from the plurality of first sub-air outlets 513. As Figure 9 shown, or, the interval distances between the plurality of first sub-air outlets 513 can be relatively far apart or relatively close; similarly, the interval distances between the plurality of second sub-air outlets 514 can be relatively far apart or relatively close.

[0076] In one embodiment, after the plurality of first sub-air outlets 513 are continuously arranged, a plurality of second sub-air outlets 514 are connected and arranged at the ends of the plurality of first sub-air outlets 513, and then a plurality of first sub-air outlets 513 are connected and arranged at the ends of the plurality of second sub-air outlets 514, and so on. The plurality of first sub-air outlets 513 and the plurality of second sub-air outlets 514 can either completely cover the barrel side wall 509 of the entire connecting barrel 500, or be continuously arranged on a part of the barrel side wall 509 of the connecting barrel 500, or the first sub-air outlets 513 and / or the second sub-air outlets 514 are arranged at intervals on the barrel side wall 509 of the connecting barrel 500. When the plurality of first sub-air outlets 513 and the plurality of second sub-air outlets 514 are arranged on a part of the barrel side wall 509 of the connecting barrel 500, the adjacent plurality of first sub-air outlets 513 and / or the plurality of second sub-air outlets 514 form a set of air outlet channels. Multiple sets of air outlet channels can be arranged on the barrel side wall 509, and so on. The multiple sets of air outlet channels are staggered, and the different sets of air outlet channels are arranged at a relatively far distance from each other.

[0077] Or other arrangement schemes of the plurality of first sub-air outlets 513 and the plurality of second sub-air outlets 514 are also within the scope of protection here, and will not be listed one by one here.

[0078] The third air outlet 303 on the reflector 301 can be set corresponding to the number and position of the second air outlets 506, or only one third air outlet 303 can be provided on the reflector 301, and the third air outlet 303 is set corresponding to one of the second air outlets 506.

[0079] Further, in order to improve the stability of the cold air flowing in the heat dissipation cavity 501.

[0080] The first air outlets 505 are respectively arranged on both sides of the second air outlet 506, and the first air outlets 505 and the second air outlet 506 are arranged adjacent to each other.

[0081] As Figure 10 shown, on the barrel side wall 509 of the connecting barrel 500, the second air outlet 506 and the two adjacent first air outlets 505 on both sides form a set of air outlet channels, which can either cover the barrel side wall 509 through a set of air outlet channels, or arrange a set of air outlet channels in a partial area on the barrel side wall 509; or multiple sets of air outlet channels are provided, and the multiple sets of air outlet channels on the barrel side wall 509 can be arranged continuously, or can be arranged at intervals between multiple sets of air outlet channels.

[0082] Because the first air outlet 505 and the second air outlet 506 are adjacent to each other, when the cold air passes through one of the first air outlet 505 or the second air outlet 506, it can quickly pass through the other second air outlet 506 or the first air outlet 505, which can reduce the probability of the cold air generating turbulence in the heat dissipation cavity 501 and enhance the stability of the cold air flowing in the heat dissipation cavity 501.

[0083] At the same time, because the rotation direction of the cooling fan 502 includes a forward rotation direction and a reverse rotation direction, when the cooling fan 502 rotates in the forward rotation direction, the cold air is discharged to the outside from the first air outlet 505 adjacent to one side of the second air outlet 506; when the cooling fan 502 rotates in the reverse rotation direction, the cold air is discharged to the outside from the first air outlet 505 adjacent to the other side of the second air outlet 506. In this way, no matter which direction the cooling fan 502 rotates, it can be quickly discharged to the outside from the first air outlet 505, completing the requirement of cooling the drive motor 309 and the connecting barrel 500 with cold air.

[0084] Further, in order to improve the exchange rate between the heat dissipation cavity 501 and the outside.

[0085] A plurality of first sub-air outlets 513 and a plurality of second sub-air outlets 514 are arranged continuously along the circumference of the barrel side wall 509.

[0086] On both sides of the second sub-air outlet 514, a plurality of first sub-air outlets 513 are arranged at intervals continuously along the circumferential direction of the cylinder side wall 509. The first sub-air outlets 513 and the second sub-air outlets 514 together cover the entire circumferential direction of the cylinder side wall 509. The circumferential arrangement can enable the cold air to quickly enter the outside directly through the first air outlet 505, so that when the driving motor 309 starts to work and when the hot air component 302 works, the heat transferred to the driving motor 309 and the connecting cylinder 500 can be taken out to the outside by the cold air through the first air outlet 505 in the first time.

[0087] At the same time, because the first sub-air outlets 513 and the second sub-air outlets 514 are arranged continuously, when a part of the cold air in the heat dissipation cavity 501 enters the first air outlet 505, another part of the cold air in the heat dissipation cavity 501 will smoothly enter the mixing channel 507 along the cylinder side wall 509 of the connecting cylinder 500 and be discharged to the outside from the second sub-air outlet 514, and the cold air can flow stably in the heat dissipation cavity 501.

[0088] In order to enable the cold air to be discharged to the outside evenly from the first air outlet 505, the first air outlet 505 is arranged at intervals and evenly on the cylinder side wall 509 of the connecting cylinder 500, and the first air outlet 505 covers the entire cylinder side wall 509 of the connecting cylinder 500. In this way, when the cold air moves from the top of the connecting cylinder 500 towards the cylinder side wall 509, the cold air at different circumferential positions can be discharged to the outside from the inside of the heat dissipation cavity 501 by moving basically the same distance and passing basically the same time.

[0089] Furthermore, in order to enable the cold air to smoothly flow out from the first air outlet 505 and the second air outlet 506, the first air outlet 505 and the second air outlet 506 have the same height.

[0090] The first air outlet 505 and the second air outlet 506 having the same height means that: the lowest points of the first air outlet 505 and the second air outlet 506 are at the same height, the highest points of the first air outlet 505 and the second air outlet 506 are at the same height, and at the same time, the extension lengths of the first air outlet 505 and the second air outlet 506 are the same. In this way, when the cooling fan 502 rotates to generate cold air, the cold air will rotate along the shape of the connecting cylinder 500. When the cold air encounters the first air outlet 505 and the second air outlet 506, it will enter the first air outlet 505 and the second air outlet 506 and be discharged to the outside.

[0091] When the heights of the first air outlet 505 and the second air outlet 506 are different, for example, when the height of the first air outlet 505 is higher than that of the second air outlet 506, most of the cold air generated by the cooling fan 502 will be discharged to the outside from the higher first air outlet 505, and only a small amount of cold air will enter the second air outlet 506. This will not only result in less cold air heat at the second air outlet 506, thus affecting the effect of reducing the hot air heat when the cold air and the hot air are mixed in the mixing channel 507; at the same time, when a small amount of cold air enters the second air outlet 506, due to the small amount of cold air, the pressure difference between the pressure in the mixing channel 507 and the pressure at the third air outlet 303 is small, and it is not possible to well allow the hot air to enter the mixing channel 507 from the cooking cavity 400, thereby prolonging the hot air discharge time. If the flow rate of the hot air discharged to the outside is small, there will still be a large amount of hot air and water vapor in the cooking cavity 400 after cooking. When the cover 300 is opened after cooking, a large amount of water vapor will gush out, causing burns to the user.

[0092] If the height of the first air outlet 505 is lower than that of the second air outlet 506, most of the cold air generated by the cooling fan 502 will be discharged to the outside from the higher second air outlet 506, and only a small amount of cold air will be discharged to the outside from the first air outlet 505. In this way, a large amount of cold air will enter the inside of the mixing channel 507. Although the large amount of cold air entering the mixing channel 507 will increase the pressure difference between the pressure in the mixing channel 507 and the pressure at the third air outlet 303, enabling the hot air to enter the mixing channel 507 at a faster speed and reducing the probability of the hot air entering the heat dissipation cavity 501. However, the large amount of cold air will rapidly reduce the temperature in the mixing channel 507, causing more condensed water to be generated when the hot air and the cold air are in the mixing channel 507, thus making it easy for bacteria to breed inside the air fryer 100 and affecting the sanitary environment inside the air fryer 100.

[0093] At the same time, if the first air outlet 505 and the second air outlet 506 are not set at the same height, when the cold air is discharged from the first air outlet 505 and the second air outlet 506 at different heights, it will cause disorder of the cold air in the heat dissipation cavity 501, affecting the discharge effect of the cold air from the first air outlet 505 and the second air outlet 506.

[0094] Such as Figure 2 and Figure 3As shown, the connecting cylinder 500 further includes a top wall 508. The cylinder side wall 509 includes a guiding wall 510 at the upper end and an air outlet wall 511 at the lower end. The first air outlet 505 and the second air outlet 506 are both provided on the air outlet wall 511. The guiding wall 510 extends downward and outward, and the guiding wall 510 is located above the first air outlet 505 and the second air outlet 506. In one embodiment, the guiding wall 510 is inclined between the top wall 508, or the guiding wall 510 is perpendicular to the top wall 508.

[0095] The guiding wall 510 and the air outlet wall 511 can be integrally provided or separately provided. When the guiding wall 510 and the air outlet wall 511 are integrally provided, the cylinder side wall 509 formed by the guiding wall 510 and the air outlet wall 511 is in direct contact connection with the main body 512 at the bottom end. At this time, the driving motor 309 is hoisted on the connecting cylinder 500.

[0096] In order to enable the cold air to be uniformly discharged to the outside from the preset positions and preset angles on the connecting cylinder 500, the guiding wall 510 is arranged around the outer periphery of the top wall, and the guiding wall 510 is closed. The cold air is discharged from the first air outlet 505 and the second air outlet 506 on the air outlet wall 511.

[0097] When the cooling fan 502 starts to rotate, cold air will be generated. The cold air is thrown out from the fan blades of the cooling fan 502 and collides with the guiding wall 510. Because the guiding wall 510 extends downward and outward obliquely, after the cold air contacts the guiding wall 510, it flows downward and outward under the guiding action of the guiding wall 510, and the cold air can flow downward along the extending direction of the guiding wall 510 and then enter the first air outlet 505 and the second air outlet 506 on the air outlet wall 511.

[0098] Furthermore, in order to improve the technical problem of the air outlet efficiency of the cold air from the first air outlet 505, the air outlet wall 511 extends obliquely downward along the height direction of the air fryer 100.

[0099] The extending direction of the air outlet wall 511 is the same as the extending direction of the guiding wall 510. Because the cold air flows obliquely downward, setting the extending direction of the air outlet wall 511 to be the same as the extending direction of the guiding wall 510 can not only enable the cold air to smoothly flow from the guiding wall 510 to the air outlet wall 511 along the obliquely downward direction, but also reduce the energy loss of the cold air flowing through the guiding wall 510 and the air outlet wall 511 or change the flow direction of the cold air.

[0100] Meanwhile, since the first air outlet 505 and the second air outlet 506 are arranged along the height direction of the air outlet wall 511, the inclined air outlet wall 511 can increase the sizes of the first air outlet 505 and the second air outlet 506, and when the cold air flows through the first air outlet 505 and the second air outlet 506 arranged on the air outlet wall 511, it can be discharged to the outside in the shortest time.

[0101] As Figure 1 , Figure 5 and Figure 6 shown, further, to solve the technical problem of low discharge efficiency of hot air from the third air outlet 303, the hot air assembly 302 includes a hot fan 304 and a heating pipe 307 arranged below the hot fan 304, and the hot fan 304 and the third air outlet 303 at least partially overlap in the height direction of the air fryer 100.

[0102] Since hot air has the property of rising upwards, if the position of the hot fan 304 relative to the third air outlet 303 is too high, the downward hot air generated by the hot fan 304 will conflict with the automatically upward hot air. At the same time, because the downward hot air has a greater kinetic energy due to the action of the hot fan 304, when the downward hot air collides with the upward hot air, the kinetic energy of the downward hot air is greater, and the overall hot air will move downward. At this time, only a small amount of hot air or even no hot air is discharged from the third air outlet 303, and only when the cooking cavity 400 is filled with hot air will more hot air gradually be discharged from the third air outlet 303.

[0103] If the position of the hot fan 304 relative to the third air outlet 303 is too low, the automatically rising hot air will also conflict with the downward hot air generated by the hot fan 304 before it rises to the height of the third air outlet 303.

[0104] Therefore, in order to improve the discharge efficiency of hot air from the third air outlet 303, the highest point of the hot fan 304 is set at a position higher than the lowest point of the third air outlet 303, or the lowest point of the hot fan 304 is set at a position lower than the highest point of the third air outlet 303. In this way, when the hot fan 304 rotates, the downward part of the hot air will be mixed with the upward hot air and directly enter the mixing channel 507. Most of the hot air entering the mixing channel 507 is the downward hot air generated by the hot air assembly 302, and a small part is the upward hot air that rebounds, thus improving the discharge efficiency of hot air from the third air outlet 303.

[0105] As Figure 1 , Figure 5 and Figure 6As shown, further, to solve the technical problem of low discharge efficiency of hot air from the third air outlet 303, the lowest point of the hot air fan 304 is lower than the lowest point of the third air outlet 303, and the highest point of the hot air fan 304 is higher than the lowest point of the third air outlet 303.

[0106] If the hot air fan 304 is completely surrounded by the third air outlet 303, the hot air generated by the hot air fan 304 will first enter the third air outlet 303. The function of the air fryer 100 to generate hot air is to heat the food in the cooking cavity 400. If the hot air directly discharges from the third air outlet 303 without heating the food, it will affect the cooking efficiency of the hot air on the food.

[0107] Therefore, the lowest point of the third air outlet 303 is set to correspond to the middle part of the hot air fan 304. In this way, most of the generated hot air will first flow downward, exchange heat with the food, and then flow upward into the third air outlet 303. The position of the hot air fan 304 can not only meet the heating effect of the hot air on the food but also solve the technical problem of improving the air outlet efficiency of the hot air from the third air outlet 303.

[0108] Such as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, further, to prevent the mixed gas with a certain flow rate discharged from the second air outlet 506 from impacting the user, a connecting seat 201 is provided on the pot body 200, a connecting component 305 is provided on the cover body 300, the connecting component 305 is hinged on the connecting seat 201, and the second air outlet 506 is opened toward the hinged position.

[0109] Although the temperature of the mixed gas discharged from the second air outlet 506 has decreased significantly, if the second air outlet 506 faces the user, the mixed gas with a certain flow rate will affect the user experience. Therefore, the second air outlet 506 is set in the direction of the hinged position, so that the mixed gas will be discharged from the back of the air fryer 100 to the outside.

[0110] Further, to prevent the mixed gas from blowing into the internal components of the connecting seat 201 and the connecting component 305 for a long time, a wind dividing plate 504 is provided in the area where the second air outlet 506 is opposite to the third air outlet 303. The wind dividing plate 504 is inclined so that the mixed wind discharged from the second air outlet 506 is discharged away from the hinged position, that is, the direction of the mixed wind discharged from the second air outlet is not directly opposite to the hinged position.

[0111] Since electrical components such as a circuit board are provided inside the cover 300, as well as a hinge device for connecting the component 305 and the connection base 201, if the mixed gas jets on the electrical components such as the circuit board and the hinge device for a long time, it will cause certain damage to the electrical components such as the circuit board and the hinge device. When the electrical components such as the circuit board are in contact with the gas for a long time, there may be a short - circuit situation. When the hinge device is in contact with the gas for a long time, it will affect the connection effect between the connecting component 305 and the connection base 201.

[0112] Therefore, an inclined air - dividing plate 504 is provided in the area where the second air outlet 506 faces the third air outlet 303. The inclined air - dividing plate 504 guides the mixed gas to blow out from both sides of the hinge position, which can not only prevent the mixed gas from impacting the user, but also prevent the mixed gas from directly blowing on the hinge position.

[0113] Furthermore, in order to provide enough space for the hot air fan 304, the reflecting cover 301 extends upward into the space enclosed by the connecting cylinder 500, and a third air outlet 303 is provided on the side wall of the reflecting cover 301.

[0114] The reflecting cover 301 provided with an upward bulge can provide enough space for the hot air fan 304 so that the hot air fan 304 and the second air outlet 506 can be at least partially overlapped.

[0115] Furthermore, in order to enable the cold air and hot air in the heat dissipation cavity 501 and the cooking cavity 400 to be quickly discharged to the outside.

[0116] The rotation directions of the hot air assembly 302 and the heat dissipation fan 502 include a forward rotation direction and a reverse rotation direction, and the air - dividing plate 504 is inclined along the forward rotation direction.

[0117] When the hot air assembly 302 and the heat dissipation fan 502 rotate forward, most of the cold air and hot air can be discharged to the outside through the first air outlet 505, the second air outlet 506 and the third air outlet 303. A large amount of liquid and gas are mixed in the hot air. At this time, it is necessary to increase the exhaust volume to achieve the effect of crispy roasting of food. When the hot air assembly 302 and the heat dissipation fan 502 rotate in the reverse direction, most of the cold air is discharged to the outside through the first air outlet 505, the discharge of cold air from the second air outlet 506 is inhibited, most of the hot air circulates in the cooking cavity 400, and the discharge of hot air from the third air outlet 303 is inhibited, which can keep the moisture of the food materials and achieve the effect of tender roasting.

[0118] In order to enable more hot air to be discharged to the outside when the hot air component 302 rotates forward, the inclination direction of the air distribution plate 504 is set along the forward rotation direction of the hot air component 302 and the cooling fan 502. In this way, when the hot air contacts the air distribution plate 504 through the third air outlet 303, the air distribution plate 504 can guide the gas and liquid to enter the mixing channel 507 through the third air outlet 303. At the same time, it can also guide the cold air in the heat dissipation cavity 501 so that more cold air enters the mixing channel 507 to be mixed with the hot air.

[0119] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification. When the technical features in different embodiments are shown in the same drawing, the drawing can be regarded as simultaneously disclosing the combination examples of the various embodiments involved.

[0120] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
