Description

TECHNICAL FIELD

[0001] The present application relates to the field of small household appliances, in particular to an air fryer. BACKGROUND

[0002] In daily life, people use air fryers more and more to cook and heat food. Usually, food is placed in a cooking cavity, and hot air is transmitted into the cooking cavity by a hot air assembly to heat the food placed in the cooking cavity. If the hot air cannot be discharged from the cooking cavity, the continuously increasing hot air will keep blowing on the food, causing the food to dry out. Meanwhile, during the heating of the food by the hot air, a large amount of water vapor is generated. If the water vapor cannot be discharged to the outside in time, when the cooking cavity is opened after cooking, the pressure inside the cooking cavity is relatively high due to the accumulation of a large amount of water vapor, and a large amount of water vapor will gush out when the cooking cavity is opened. If the user operates improperly, the gushing water vapor can easily cause burns to 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 is usually connected to the outside through a pipeline to realize the guiding effect of the hot air. For example, in Chinese Utility Model Patent CN219613676U, the air outlet assembly includes an air inlet pipe, a vapor containing cavity and an air guide pipe connected in sequence. The air inlet pipe is connected to the cooking cavity, and the air guide pipe is connected to the outside. In this way, the air outlet assembly can be used to discharge the water vapor and hot air in the cooking cavity to avoid the accumulation of too much water vapor and hot air in the cooking cavity, which can cause poor food taste or excessive pressure in the cooking cavity, causing unsafe use, etc.

[0004] However, the direct discharge of water vapor and hot air in the cooking cavity through the air outlet assembly can discharge the water vapor and hot air in the cooking cavity in time, but the temperature of the water vapor and hot air discharged from the air outlet assembly is still high because the water vapor and hot air are not cooled during the discharge process. If the air outlet assembly of the air fryer is arranged close to a wall, the high-temperature water vapor and hot air can damage the wall. Or when the user checks the cooking condition of the air fryer, the high-temperature water vapor and hot air can directly scald the user.

[0005] For some air fryers, the cover body includes a glass panel, and the glass panel is directly arranged on the pot body. In order to enable the water vapor and hot air in the cooking cavity to be discharged to the outside, an air vent hole is arranged on the glass panel, and the air vent hole communicates the cooking cavity with the outside. In this way, when a certain amount of hot air and water vapor accumulates in the cooking cavity, the hot air and water vapor will be discharged to the outside along the air vent hole. As mentioned above, the direct discharge of hot air and water vapor to the outside can 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 Chinese utility model patent CN215687021U, a first fan leaf for generating cold air and a second fan leaf for generating hot air are provided. The cold air enters the confluence cavity through the first confluence inlet, and the hot air enters the confluence cavity through the second confluence inlet. The cold air and the hot air are mixed and cooled in the confluence cavity, and then discharged to the outside. The water vapor is also cooled and discharged to the outside with the mixing of the hot air and the cold air. In this way, the temperature of the discharged hot air and water vapor is reduced, reducing the probability of burns to the user.

[0007] All the cold air generated by the first fan leaf and all the hot air generated by the second fan leaf enter the confluence cavity for mixing. When the hot air meets a large amount of cold air in a short time, the temperature of the hot air will drop sharply, and the water vapor carried by the hot air with a high temperature will be liquefied to produce condensed water. The condensed water will adhere to the confluence cavity and cannot be discharged. Long-term accumulation will accumulate a large amount of condensed water, which is easy to breed bacteria in the air fryer. SUMMARY

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

[0009] The air fryer of the present application comprises a pot body and a cover body covering the pot body. The cover body and the pot body form a cooking cavity. A reflector is provided on the cover body. The reflector is provided with a hot air assembly for generating hot air on the side facing the cooking cavity. The side of the reflector away from the cooking cavity is provided with a connecting cylinder. The connecting cylinder and the reflector cooperate to form a heat dissipation cavity. A heat dissipation fan is provided in the heat dissipation cavity for generating cold air. An air outlet is provided on the cylinder side wall of the connecting cylinder. The cylinder side wall of the connecting cylinder is provided with a plurality of air distribution plates. The air outlet is divided into a first air outlet and a second air outlet by the plurality of air distribution plates. A mixing channel is formed between the plurality of air distribution plates. Mixed gas in the mixing channel is discharged from the second air outlet. A third air outlet is provided on the reflector. The third air outlet communicates the cooking cavity and the mixing channel. Hot air in the cooking cavity enters the mixing channel through the third air outlet, mixes with the cold air in the heat dissipation cavity, and is discharged to the outside.

[0010] The following also provides several optional modes, but not as an additional limitation to the above overall scheme, just a further supplement or preferred, without technical or logical contradiction, each optional mode can be combined with the above overall scheme, and can also be combined between multiple optional modes.

[0011] Further, the reflector is upwardly and protrudingly extended to form a reflector sidewall, and the third air outlet is arranged on the reflector sidewall, and the air distribution plate extends from the barrel sidewall to the direction close to the reflector sidewall.

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

[0013] A plurality of air outlets are arranged on the barrel sidewall in a spaced manner, and at least one air outlet is provided with a plurality of air distribution plates to divide the air outlet into the first air outlet and the second air outlet.

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

[0015] The first air outlet is arranged on both sides of the second air outlet and arranged along the circumferential direction of the barrel sidewall of the connecting barrel.

[0016] The pot body is provided with a connecting seat, the cover body is provided with a connecting assembly, the connecting assembly 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 opposite to the second air outlet and the third air outlet, and the air distribution plate is arranged in an inclined manner.

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

[0019] The rotation direction of the hot air assembly and the heat dissipation fan includes a forward rotation direction and a reverse rotation direction, and the air distribution plate is arranged in an inclined manner along the forward rotation direction.

[0020] Further, in order to enable the cold air to be unable to smoothly discharge from the air outlet.

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

[0022] Further, in order to solve the technical problem that the cold air flow path is not fixed.

[0023] Further, the barrel sidewall includes a guide wall, the guide wall extends downwardly and outwardly, and the guide wall is located above the first air outlet and the second air outlet.

[0024] The air fryer of the application is provided with a first air outlet and a second air outlet on the connecting cylinder. Part of the cold air generated by the cooling fan enters the 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 the user is not easy to be scalded after the mixed air is discharged to the outside from the second air outlet. Thus, part of the cold air is discharged from the first air outlet, and part of the cold air is mixed with the hot air discharged from the third air outlet to reduce the temperature. The amount of cold air mixed with the hot air is reduced to prevent condensate water from being generated when the cold air is mixed with the hot air.

[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 to be discharged from the mixing channel to the second air outlet.

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

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

[0028] The first air outlet is arranged on both sides of the second air outlet, and the first air outlet and the second air outlet are arranged adjacently. Because the first air outlet and the second air outlet are arranged adjacently, when the cold air passes through one of the first air outlet or the second air outlet, the cold air can quickly pass through the other second air outlet or first air outlet. This can reduce the probability of turbulence of the cold air in the cooling cavity and enhance the stability of the flow of the cold air in the cooling cavity.

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

[0030] The plurality of first sub-air outlets and the plurality of second sub-air outlets are arranged continuously along the circumference of the cylinder side wall. In order to enable the cold air to be discharged uniformly from the first air outlet to the outside, the first air outlets are arranged uniformly and spaced apart on the cylinder side wall of the connecting cylinder, and the air outlets cover the entire cylinder side wall of the connecting cylinder. Thus, when the cold air moves from the top end of the connecting cylinder to the cylinder side wall, the cold air at different circumferential positions can be discharged from the inside of the cooling cavity to the outside in substantially the same distance and in substantially the same time.

[0050] As shown in Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , and Figure 7 An air fryer 100, including a pot body 200 and a cover body 300 covering the pot body 200, the cover body 300 and the pot body 200 enclosing a cooking cavity 400, a reflecting cover 301 is arranged on the cover body 300, the reflecting cover 301 is provided with a hot air assembly 302 for generating hot air on the side facing the cooking cavity 400, the reflecting cover 301 is provided with a connecting cylinder 500 on the side away from the cooking cavity 400, the connecting cylinder 500 cooperates with the reflecting cover 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, a first air outlet 505 and a second air outlet 506 are arranged on the cylinder side wall 509 of the connecting cylinder 500, a part of the cold air in the heat dissipation cavity 501 is discharged to the outside from the first air outlet 505, the cylinder side wall 509 of the connecting cylinder 500 is provided with a wind distribution plate 504, a mixing channel 507 is formed between the plurality of wind distribution plates 504, mixed gas in the mixing channel 507 is discharged from the second air outlet 506, a third air outlet 303 is arranged on the reflecting cover 301, the third air outlet 303 communicates the cooking cavity 400 with the mixing channel 507, the hot air in the cooking cavity 400 enters the mixing channel 507 through the third air outlet 303 and mixes with another part of the cold air in the heat dissipation cavity 501 to be discharged to the outside.

[0051] The air baffle 504 can divide the cold air generated by the heat dissipation cavity 501, so that part of the cold air flows out of the first air outlet 505 to the outside, and the other part of the cold air enters the mixing channel 507 and is mixed with the hot air to be discharged from the second air outlet 506 to the outside, thereby reducing the heat when the hot air is discharged and reducing the generation of condensed water.

[0052] In the embodiment, the air fryer 100 includes a pot body 200 and a cover body 300, the cover body 300 is covered above the pot body 200, and a cooking cavity 400 for containing food is formed between the cover body 300 and the pot body 200. A reflecting cover 301 is arranged on the cover body 300, the cooking cavity 400 is arranged below the reflecting cover 301, a hot air assembly 302 is arranged in the cooking cavity 400, the hot air assembly 302 includes a heating pipe 307 and a hot air fan 304, and a driving motor 309 and a heat dissipation fan 502 are arranged above the reflecting cover 301. The cover body 300 and the pot body 200 can be hingedly connected, and the cover body 300 can be reversed relative to the pot body 200 to open or close the cooking cavity 400. Of course, the cover body 300 can be directly arranged on the pot body 200, and of course, the cover body 300 can be coupled to the pot body 200.

[0053] The cover body 300 has a first position in which the cover body 300 and the pot body 200 are covered with each other, and a second position in which the cover body 300 is flipped or plugged relative to the pot body 200 to make the pot body 200 in an open state. For example, the pot body 200 and the cover body 300 are hingedly flipped together, before cooking, the user reverses the cover body 300 to make the cover body 300 in the second position, at this time, the cover body 300 and the pot body 200 are in an open state, and the user puts food into the cooking cavity 400. During cooking, the user reverses the cover body 300 again to make the cover body 300 in the first position, at this time, the cover body 300 and the pot body 200 are in a closed state.

[0054] The cover body 300 includes a body 512, a machine head 308, and a connecting barrel 500 connected between the body 512 and the machine head 308. The connecting barrel 500 guides the cold air generated by the heat dissipation fan 502 to flow along the outer contour shape of the connecting barrel 500. The first air outlet 505 and the second air outlet 506 are arranged on the barrel side wall 509 of the connecting barrel 500 to connect the heat dissipation cavity 501 and the outside. 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 arranged on the barrel side wall 509 of the connecting barrel 500 to exchange corresponding gas or liquid.

[0055] The connecting cylinder 500 is a hollow cylindrical structure, the cross section of the connecting cylinder 500 can be circular, square, oval or irregular shape, and the specific shape is not limited. Preferably, the connecting cylinder is a narrow-top wide-bottom cylindrical structure as shown in the figure. Figure 4 The narrow-top wide-bottom cylindrical structure is shown in the figure.

[0056] Generally, when the driving motor 309 is arranged in the air fryer 100, a large amount of heat is generated inside the driving motor 309 during the operation of 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. Another part of the cold air generated by the cooling fan 502 enters the mixing channel 507 and is discharged to the outside through the second air outlet 506.

[0057] Preferably, the cover 300 and the pot 200 are sealingly connected. When the hot air assembly 302 generates hot air, the pressure in the cooking cavity 400 will gradually increase due to the hot air and the steam generated during cooking. Because the third air outlet 303 is arranged on the reflector 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 be discharged to the outside of the cooking cavity 400, preventing the pressure in 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, and the third air outlet 303 on the reflector 301 is arranged opposite to the second air outlet 506 on the connecting cylinder 500. The air distribution plate 504 guides the hot air from the third air outlet 303 into the mixing channel 507 and discharges it to the outside. At this time, 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 distribution plate 504 is arranged, 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 the air distribution plate 504 is not arranged between the first air outlet 505 and the second air outlet 506, most of the hot air will enter the cavity inside the heat dissipation cavity 501 after passing through the third air outlet 303. After the hot air enters the cavity inside the heat dissipation cavity 501, condensate water is generated after the hot air and the cold air contact each other, which causes the air fryer 100 to be difficult to clean and affects the user's 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 hot air, and avoiding the situation that the water vapor in the hot air is rapidly cooled and liquefied to generate condensate water.

[0060] The number of air distribution plates 504 can be set to 2, and the opposite sides of the two air distribution plates 504 form the mixing channel 507. By arranging the two air distribution plates 504, part of the cold air is discharged to the outside from 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 the hot air entering the mixing channel 507 from generating turbulence, at least one air distribution plate 504 is additionally arranged in the middle of the two air distribution plates 504. As a preferred scheme, the number of air distribution plates 504 is set to 4. In this way, the cold air and the hot air entering the mixing channel 507 can be divided into multiple air channels, so that the cold air and the hot air can be smoothly discharged to the outside from the mixing channel 507, preventing the cold air and the hot air from appearing in the mixing channel 507.

[0062] The air distribution plate 504 can be a long strip-shaped plate structure or a cylindrical structure, as long as part of the cold air can enter the middle of the air distribution plate 504 to mix with the hot air.

[0063] The mixing channel 507 is arranged in the radial direction of the air fryer 100 and has a certain length. When the heat dissipation fan 502 rotates to generate cold air, the cold air enters the mixing channel 507 in the radial direction of the air fryer 100; the hot air enters 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, so the pressure in the mixing channel 507 is less than that at the third air outlet 303. The hot air is sucked into the mixing channel 507, which not only speeds up the entry of the hot air into the mixing channel 507, but also effectively prevents the hot air from entering the heat dissipation cavity 501.

[0064] Because the driving motor 309 generates a large amount of heat during high-speed operation, and the heat generated by the heating pipe 307 in the hot air assembly 302 is also partially transferred to the driving motor 309 and the connecting cylinder 500, if the driving motor 309 and the connecting cylinder 500 cannot be cooled in time, the driving motor 309 will stop working because it heats up too quickly, or some parts of the driving motor 309 will deform because they cannot withstand high temperatures, and the connecting cylinder 500 will also deform because it is in a high-temperature state for a long time. Therefore, the air fryer 100 is provided with a cooling fan 502 to cool the driving motor 309 and the connecting cylinder 500 by the cold air generated by the cooling fan 502. The cold air generated by the cooling fan 502 is used to cool the driving motor 309 and the connecting cylinder, and 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 enters the mixing channel 507 together with the hot air discharged from the cooking cavity 400, and the cold air and the hot air are mixed in the mixing channel 507 to form mixed air, which has a lower temperature and is less likely to scald the user after being discharged to the outside from the second air outlet 506. At the same time, the air is physically separated by the air distribution plate 504 to prevent the hot air from escaping from the mixing channel 507 and entering the area outside the mixing channel 507 of the cooling cavity 501 to mix with a large amount of cold air and quickly cool down to form condensed water; at the same time, only part of the cold air enters the mixing cavity to prevent the generation of condensed water caused by the rapid reduction of the temperature in the mixing channel 507.

[0065] In an embodiment of the present application, the driving motor 309 is used to drive the rotation of the hot fan 304 and the cooling fan 502, and the driving motor 309 is fixed on the connecting cylinder 500. In this way, the driving motor 309 is suspended on the handle 308, which can reduce the overall height of the driving motor 309, thereby achieving the effect of making the handle 308 thinner.

[0066] In another embodiment of the present application, the connecting cylinder 500 further comprises a top wall 508, and the upper edge of the cylinder side wall 509 extends radially inward to form the top wall 508, and the driving motor 309 is mounted on the top wall 508. The driving motor 309 is mounted on the upper end of the connecting cylinder 500, specifically, the lower end of the driving motor 309 can be mounted on 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. Alternatively, the upper end of the driving motor 309 can be mounted on the lower end of the connecting cylinder 500, that is, the driving motor 309 is suspended on the connecting cylinder 500.

[0067] Attached Figure 1 ~ Attached Figure 7Only the air fryer 100 with the cover opened by the hinged device is given, the connecting cylinder 500 is arranged as a cylinder structure with the top narrow and the bottom wide, and the first air outlets 505 are arranged adjacent to the two sides of the second air outlets 506, and the first air outlets 505 and the second air outlets 506 cover the cylinder side wall 509. Other embodiments are not shown in the form of drawings, but are described in words, but are within the scope of the present application.

[0068] Further, in order to enable the hot air to smoothly enter the mixing channel 507 from the cooking cavity 400.

[0069] The reflector cover 301 extends upward to form a cover side wall, and the reflector cover 301 protrudes upward along the height direction of the air fryer 100, so that part of the reflector cover coincides with part of the connecting cylinder, reducing the space of the heat dissipation cavity 501. The third air outlet 303 is arranged on the cover side wall, and the air distribution plate 504 extends from the cylinder side wall 509 to the direction close to the cover side wall.

[0070] The air distribution plate 504 can extend from the cylinder side wall 509 to the cover side wall, or extend from the cylinder top wall of the connecting cylinder 500 to the cover side wall, as long as the air distribution plate 504 is arranged to enable the hot air to smoothly enter the mixing channel 507 and be discharged from the second air outlet 506.

[0071] The air distribution plate 504 and the cover side wall can be in close contact with each other, or can have a certain spacing, and the spacing therebetween should not be too large to prevent a large amount of hot air from overflowing from the mixing channel 507, affecting the discharge efficiency of the hot air.

[0072] Further, in order to enable the cold air in the heat dissipation cavity 501 to be quickly discharged to the outside from the first air outlet 505 and the second air outlet 506.

[0073] The first air outlet 505 includes a plurality of first sub-air outlets 513, and the plurality of first sub-air outlets 513 are arranged continuously on the cylinder 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 arranged continuously on the cylinder side wall 509.

[0074] Preferably, as shown in Figure 8 A plurality of first sub-air outlets 513 are arranged continuously, and then a plurality of second sub-air outlets 514 are arranged continuously, or a plurality of first sub-air outlets 513 are connected to the rear of the plurality of second sub-air outlets 514 according to needs, and so on, and 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 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 long distance from the plurality of first sub-air outlets 513. As shown in Figure 9As shown, the spacing between multiple first sub-air outlets 513 can be either far apart or close together; similarly, the spacing between multiple second sub-air outlets 514 can be either far apart or close together.

[0075] In one embodiment, after a plurality of first sub-air outlets 513 are arranged in a continuous manner, 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 entire cylinder sidewall 509 of the connecting cylinder 500, or they can be continuously arranged on a portion of the cylinder sidewall 509 of the connecting cylinder 500, or the first sub-air outlets 513 and / or the second sub-air outlets 514 can be arranged at intervals on the cylinder sidewall 509 of the connecting cylinder 500. When multiple first sub-air outlets 513 and multiple second sub-air outlets 514 are arranged on a portion of the side wall 509 of the connecting cylinder 500, the multiple adjacent first sub-air outlets 513 and / or multiple second sub-air outlets 514 form a set of air outlet channels. Multiple sets of air outlet channels can be set on the side wall 509, and so on. The multiple sets of air outlet channels are staggered and arranged with a large distance between different sets of air outlet channels.

[0076] Alternatively, other arrangements of multiple first sub-air outlets 513 and multiple second sub-air outlets 514 are also within the scope of this protection, but will not be listed one by one here.

[0077] The third air outlet 303 on the reflector 301 can be set according to the number and position of the second air outlet 506, or only one third air outlet 303 can be set on the reflector 301, and the third air outlet 303 can be set to correspond to one of the second air outlets 506.

[0078] Furthermore, in order to improve the stability of the flow of cold air in the heat dissipation cavity 501.

[0079] The second air outlet 506 has a first air outlet 505 on each side, and the first air outlet 505 and the second air outlet 506 are arranged adjacent to each other.

[0080] like Figure 10 As shown, on the side wall 509 of the connecting cylinder 500, the second air outlet 506 and the first air outlets 505 adjacent to both sides form a set of air outlet channels. The side wall 509 can be filled with one set of air outlet channels, or a set of air outlet channels can be arranged in a part of the side wall 509; or multiple sets of air outlet channels can be provided, and the multiple sets of air outlet channels on the side wall 509 can be arranged continuously or spaced apart.

[0081] Because the first air outlet 505 and the second air outlet 506 are arranged adjacently, when the cold air passes through one of the first air outlet 505 or the second air outlet 506, the cold air can quickly pass through the other second air outlet 506 or the first air outlet 505, so that the probability of the cold air being turbulent in the heat dissipation cavity 501 is reduced, and the stability of the cold air flowing in the heat dissipation cavity 501 is enhanced.

[0082] At the same time, because the rotation direction of the heat dissipation fan 502 includes a forward rotation direction and a reverse rotation direction, when the heat dissipation fan 502 rotates along the forward rotation direction, the cold air is discharged from the first air outlet 505 adjacent to one side of the second air outlet 506 to the outside; when the heat dissipation fan 502 rotates along the reverse rotation direction, the cold air is discharged from the first air outlet 505 adjacent to the other side of the second air outlet 506 to the outside. In this way, no matter which direction the heat dissipation fan 502 rotates, the cold air can be quickly discharged from the first air outlet 505 to the outside, and the cooling demand of the cold air on the driving motor 309 and the connecting cylinder 500 is met.

[0083] Further, in order to improve the exchange rate of the cold air between the heat dissipation cavity 501 and the outside.

[0084] The plurality of first sub-air outlets 513 and the plurality of second sub-air outlets 514 are continuously arranged along the circumference of the cylinder side wall 509.

[0085] On both sides of the second sub-air outlet 514, a plurality of first sub-air outlets 513 are continuously and spacedly arranged along the circumference of the cylinder side wall 509, and the first sub-air outlets 513 and the second sub-air outlets 514 together cover the entire circumference of the cylinder side wall 509. The complete circumferential arrangement can enable the cold air to quickly pass through the first air outlet 505 and directly enter the outside, so that the heat transferred to the driving motor 309 and the connecting cylinder 500 in the first time when the driving motor 309 starts to work and when the hot air assembly 302 works can be taken out to the outside by the cold air from the first air outlet 505.

[0086] At the same time, because the first sub-air outlets 513 and the second sub-air outlets 514 are continuously arranged, 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 stably flow in the heat dissipation cavity 501.

[0087] In order to make the cold air evenly from the first air outlet 505 to the outside, the first air outlet 505 is evenly arranged on the barrel side wall 509 of the connecting barrel 500, and the first air outlet 505 covers the entire barrel side wall 509 of the connecting barrel 500, so that when the cold air moves from the top end of the connecting barrel 500 to the barrel side wall 509, the cold air at different circumferential positions can be discharged from the inside of the heat dissipation cavity 501 to the outside in basically the same time and through basically the same distance.

[0088] Further, in order to make the cold air smoothly from the first air outlet 505 and the second air outlet 506, the first air outlet 505 and the second air outlet 506 are the same height.

[0089] The same height of the first air outlet 505 and the second air outlet 506 means that the lowest point of the first air outlet 505 and the second air outlet 506 is at the same height, the highest point of the first air outlet 505 and the second air outlet 506 is at the same height, and the extension length of the first air outlet 505 and the second air outlet 506 is 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 barrel 500, and when the cold air meets 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.

[0090] When the height of the first air outlet 505 and the second air outlet 506 is different, for example, the height of the first air outlet 505 is higher than the height 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 first air outlet 505 with higher position, and only a small amount of cold air will enter the second air outlet 506. In this way, not only will the cold air at the second air outlet 506 have less heat, thereby affecting the effect of reducing the heat of the hot air when the cold air and the hot air are mixed in the mixing channel 507, but also when a small amount of cold air enters the second air outlet 506, because the amount of cold air is small, the pressure difference between the mixing channel 507 and the third air outlet 303 is small, and the hot air cannot enter the mixing channel 507 from the cooking cavity 400, thereby prolonging the time of hot air discharge. If the flow rate of the hot air discharged to the outside is small, there will be a lot of hot air and steam in the cooking cavity 400 after cooking, and when the cover 300 is opened after cooking, a large amount of steam will gush out, thereby causing scalding to the user.

[0091] If the height of the first air outlet 505 is lower than the height 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 mixing channel 507, although the large amount of cold air entering the mixing channel 507 will increase the pressure difference between the mixing channel 507 and the third air outlet 303, so that the hot air can enter the mixing channel 507 at a faster speed, and the probability of the hot air entering the cooling cavity 501 is reduced. However, a large amount of cold air will quickly reduce the temperature in the mixing channel 507, so that the hot air and the cold air will generate more condensate water in the mixing channel 507, thereby causing bacteria to breed easily in the air fryer 100, affecting the sanitary environment inside the air fryer 100.

[0092] At the same time, if the first air outlet 505 and the second air outlet 506 are not arranged at the same height, the cold air will be discharged from the first air outlet 505 and the second air outlet 506 at different heights, which will cause the cold air to be disordered in the cooling cavity 501, affecting the effect of the cold air being discharged from the first air outlet 505 and the second air outlet 506.

[0093] As shown in Figure 2 and Figure 3 The connecting cylinder 500 further includes a top wall 508, the cylinder side wall 509 includes a guide 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 arranged on the air outlet wall 511, the guide wall 510 extends downward and outward, and the guide wall 510 is located above the first air outlet 505 and the second air outlet 506. In one embodiment, the guide wall 510 is arranged inclinedly between the top wall 508, or the guide wall 510 is arranged perpendicularly to the top wall 508.

[0094] The guide wall 510 and the air outlet wall 511 can be integrally arranged or separately arranged. When the guide wall 510 and the air outlet wall 511 are integrally arranged, the cylinder side wall 509 formed by the guide wall 510 and the air outlet wall 511 is directly connected to the body 512 at the bottom end, and at this time the driving motor 309 is hoisted on the connecting cylinder 500.

[0095] In order to enable the cold air to be uniformly discharged from the predetermined position and the predetermined angle of the connecting cylinder 500 to the outside, the guide wall 510 is arranged around the outer periphery of the top wall, and the guide wall 510 is closed, and the cold air is discharged from the first air outlet 505 and the second air outlet 506 on the air outlet wall 511.

[0096] When the heat dissipation fan 502 starts to rotate, cold air is generated and is flung from the blades of the heat dissipation fan 502 to collide with the guide wall 510. Because the guide wall 510 extends obliquely downward and outward, the cold air flows downward and outward under the guidance of the guide wall 510 after contacting the guide wall 510, and the cold air can flow downward along the extension direction of the guide wall 510 and then enter the first air outlet 505 and the second air outlet 506 on the air outlet wall 511.

[0097] Further, to improve the technical problem of the efficiency of the cold air being discharged from the first air outlet 505, the air outlet wall 511 extends obliquely downward along the height direction of the air fryer 100.

[0098] The extension direction of the air outlet wall 511 is the same as that of the guide wall 510, because the cold air flows obliquely downward. Setting the extension direction of the air outlet wall 511 to be the same as that of the guide wall 510 not only enables the cold air to flow smoothly from the guide wall 510 to the air outlet wall 511 along the obliquely downward direction, but also reduces the energy loss or changes the flow direction of the cold air when the cold air flows through the guide wall 510 and the air outlet wall 511.

[0099] At the same time, because the first air outlet 505 and the second air outlet 506 are arranged along the height direction of the air outlet wall 511, the obliquely arranged air outlet wall 511 can increase the size of the first air outlet 505 and the second air outlet 506, and the cold air flowing through the first air outlet 505 and the second air outlet 506 arranged on the air outlet wall 511 can be discharged to the outside in the shortest time.

[0100] As shown in FIGS. Figure 1 , Figure 5 and Figure 6 Further, to solve the technical problem of the low efficiency of the hot air being discharged from the third air outlet 303, the hot air assembly 302 includes a hot air fan 304 and a heating pipe 307 arranged below the hot air fan 304, and the hot air fan 304 at least partially overlaps the third air outlet 303 in the height direction of the air fryer 100.

[0101] Because the hot air has the characteristic of rising upward, if the hot air fan 304 is arranged too high relative to the third air outlet 303, the downward hot air generated by the hot air fan 304 will conflict with the upward hot air, and because the downward hot air has a large kinetic energy due to the action of the hot air fan 304, when the downward hot air collides with the upward hot air, the kinetic energy of the downward hot air is large, and the whole hot air moves downward. At this time, only a small amount of hot air or even no hot air is discharged from the third air outlet 303. Only when the hot air fills the cooking cavity 400, more hot air will be gradually discharged from the third air outlet 303.

[0102] If the hot air fan 304 is set at a lower position relative to the third air outlet 303, the hot air that automatically rises upward will collide with the downward hot air generated by the hot air fan 304 before rising to the height of the third air outlet 303.

[0103] Therefore, in order to improve the efficiency of the hot air discharged from the third air outlet 303, the highest point of the hot air 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 air fan 304 is set at a position lower than the highest point of the third air outlet 303. In this way, when the hot air fan 304 rotates, the downward hot air will mix with the upward hot air and directly enter the mixing channel 507. Most of the hot air entering the mixing channel 507 is downward hot air generated by the hot air assembly 302, and a small part is upward hot air that rises back. This improves the efficiency of the hot air discharged from the third air outlet 303.

[0104] As shown in Figure 1 , Figure 5 and Figure 6 , 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.

[0105] 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 hot air generated by the air fryer 100 is to heat the food in the cooking cavity 400. The hot air that has not been heated by the food is directly discharged from the third air outlet 303 to the cooking cavity 400, which will affect the cooking efficiency of the hot air on the food.

[0106] Therefore, the lowest point of the third air outlet 303 is set to correspond to the middle part of the hot air fan 304. 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 satisfy the heating effect of the hot air on the food and improve the technical problem of the efficiency of the hot air discharged from the third air outlet 303.

[0107] As shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , further, in order to prevent the mixed gas body 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 assembly 305 is provided on the cover body 300, the connecting assembly 305 is hinged on the connecting seat 201, and the second air outlet 506 is opened towards the hinged position.

[0108] Although the temperature of the mixed gas body discharged from the second air outlet 506 has been significantly reduced, if the second air outlet 506 is directed towards the user, the mixed gas body with a certain flow rate will affect the user's experience, so the second air outlet 506 is arranged in the direction of the hinge position, so that the mixed gas body is discharged from the back of the air fryer 100 to the outside.

[0109] Further, in order to prevent the mixed gas body from blowing the connecting seat 201 and the internal components of the connecting assembly 305 for a long time, a baffle plate 504 is arranged in the area opposite the second air outlet 506 and the third air outlet 303. The baffle plate 504 is arranged obliquely, so that the mixed air discharged from the second air outlet 506 is discharged away from the hinge position, that is, the direction of the mixed air discharged from the second air outlet is not directly opposite the hinge position.

[0110] Because the inside of the cover 300 is provided with electrical elements such as a circuit board, and a hinge device for connecting the connecting assembly 305 and the connecting seat 201, if the mixed gas body sprays gas to the circuit board and the hinge device for a long time, it will cause certain damage to the circuit board and the hinge device. The circuit board and the hinge device may be short-circuited after being in contact with the gas for a long time, and the connecting effect of the connecting assembly 305 and the connecting seat 201 will be affected if the hinge device is in contact with the gas for a long time.

[0111] Therefore, an inclined baffle plate 504 is arranged in the area opposite the second air outlet 506 and the third air outlet 303. The inclined baffle plate 504 guides the mixed gas body to be discharged from both sides of the hinge position, which can prevent the mixed gas body from impacting the user and directly blowing against the hinge position.

[0112] Further, in order to provide enough space for the hot air fan 304, the reflector 301 extends upward into the space surrounded by the connecting cylinder 500, and the third air outlet 303 is arranged on the side wall of the reflector 301.

[0113] The upwardly protruding reflector 301 can provide enough space for the hot air fan 304 to at least partially overlap the second air outlet 506.

[0114] Further, 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.

[0115] The rotation direction of the hot air assembly 302 and the heat dissipation fan 502 includes a forward rotation direction and a reverse rotation direction, and the baffle plate 504 is arranged obliquely along the forward rotation direction.

[0116] When the hot air assembly 302 and the heat dissipation fan 502 rotate forward, most of the cold air and the 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, and the hot air mixed with a large amount of liquid and vapor, at this time, the steam discharge capacity needs to be increased to achieve the effect of crisp roasting of food; when the hot air assembly 302 and the heat dissipation fan 502 rotate reversely, most of the cold air is discharged to the outside through the first air outlet 505, the discharge of the cold air to the outside through the second air outlet 506 is inhibited, most of the hot air circulates in the cooking cavity 400, the discharge of the hot air to the outside through the third air outlet 303 is inhibited, and the moisture of the food material can be maintained to achieve the effect of tender roasting.

[0117] In order to enable the hot air assembly 302 to discharge more hot air to the outside when rotating forward, the direction of the air distribution plate 504 is arranged along the forward rotation direction of the hot air assembly 302 and the heat dissipation fan 502, so that when the hot air passes through the third air outlet 303 and contacts the air distribution plate 504, the air distribution plate 504 can guide the vapor and liquid to enter the mixing channel 507 through the third air outlet 303; at the same time, the cold air in the heat dissipation cavity 501 is also guided to enter the mixing channel 507 and mix with the hot air.

[0118] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present disclosure.

[0119] The above-described embodiments only express several implementation manners of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the patent scope of the application. It should be noted that for ordinary skilled persons in the art, without departing from the concept of the present application, some modifications and improvements can be made, which are within the scope of the present application.
