Description

Technical Field

[0001] The utility model relates to the technical field of air fryers. Background Art

[0002] An air fryer is a kitchen appliance that uses an air heating component and the hot air circulation airflow it generates to bake food.

[0003] In the related art, a fan assembly is usually provided on the inner side of the air fryer, and the fan assembly includes a cooling fan and a heating fan. When the cooling fan rotates, the cold air flow is discharged in time through the exhaust port of the outer shell, and when the heating fan rotates, part of the hot air flow in the cooking chamber is discharged through the exhaust port of the outer shell.

[0004] To prevent the hot air from being too hot and causing the wall behind the air fryer to overheat, the hot and cold air are usually mixed before being discharged to the outside environment. The mixed air is then discharged through the exhaust vents of the outer shell. This arrangement can effectively reduce the temperature of the hot air. However, this arrangement can easily cause airflow to be blocked inside the exhaust vents, which in turn prevents the hot and cold air from being discharged to the outside environment in a timely manner.

[0015] According to some embodiments of the present invention, the angle between the direction of the air fryer toward the top thereof and the first direction is set between 30° and 60°.

[0016] According to some embodiments of the present invention, the first air guide port is used to discharge the cold air flow horizontally outward or obliquely downward to the external environment in the first direction relative to the height direction of the air fryer.

[0019] According to some embodiments of the present invention, the second air guiding rib has a first air guiding surface extending vertically or obliquely upward on the side facing the cold air outlet.

[0020] According to some embodiments of the present invention, a second wind guide surface extending obliquely upward is provided on the side of the second wind guide rib facing away from the first wind guide surface, and the upward inclination angle of the first wind guide surface is greater than the upward inclination angle of the second wind guide surface.

[0021] According to some embodiments of the present invention, the first air guide port is used to discharge the cold air flow downwardly to the external environment in the first direction relative to the height direction of the air fryer;

[0022] The second air guide port is used to discharge the hot air flow horizontally outward or obliquely downward to the external environment in the second direction relative to the height direction of the air fryer, so that the cold air flow and the hot air intersect in the direction away from the air outlet.

In this way, the mixing of the hot air flow and the cold air flow will not affect the exhaust effect of the air fryer on the hot air flow and the cold air flow, thereby ensuring that the air fryer can discharge the cold air flow and the hot air flow generated in the air fryer in a timely manner, thereby ensuring the heat dissipation effect of the air fryer.

[0029] In addition, the air fryer controls the outward blowing direction of the hot air flow and the cold air flow, thereby controlling the mixing of the hot air flow and the cold air flow in the external environment behind the air fryer.

For example, the blowing direction of the hot air flow and the cold air flow can be controlled by controlling the orientation of the first air guide port and the second air guide port. It can be seen that the present application not only satisfies the mixing of the hot air flow and the cold air flow, but also ensures that the structure of the air fryer is relatively simple, thereby saving the manufacturing cost of the air fryer.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings.

[0046] For the sake of convenience, the height direction of the air fryer refers to the direction between the bottom of the air fryer and the top of the air fryer. More specifically, if the air fryer is placed on a horizontal platform, the height direction of the air fryer refers to the vertical direction between the bottom of the air fryer and the top of the air fryer.

[0047] See also Figures 1 to 2The air fryer provided in an embodiment of the present invention includes a housing 100 and an air guide base 200. The housing 100 is provided with an exhaust vent 110 communicating with the external environment, and the exhaust vent 110 is typically located at the rear side of the air fryer. A cooking cavity 120 is provided within the housing 100, and a placement opening 130 communicating with the cooking cavity 120 is typically provided at the front side of the housing 100. A cooking container 900 containing food can be placed into the cooking cavity 120 through the placement opening 130 to cook the food in the cooking container 900. The air guide base 200 is assembled and connected to the exhaust vent 110 and is provided with a first air guide vent 211 and a second air guide vent 221 communicating with the external environment. Among them, the air guide seat 200 is not limited to being provided with only one. The air guide seat 200 can be provided with one or more, and each air guide seat 200 is provided with a first air guide outlet 211 and a second air guide outlet 221 at the same time, or, there are two air guide seats 200, one air guide seat 200 is provided with a first air guide outlet 211, and the other air guide seat 200 is provided with a second air guide outlet 221, and the two air guide seats 200 are respectively installed on the exhaust outlet 110 of the outer shell 100.

[0048] The air fryer further includes an air guide housing 300, a reflector 400, a cooling fan 500, a heating fan 600, and a heating unit 700. The heating fan 600 and the heating unit 700 are located above the cooking cavity 120, or more specifically, at the top of the cooking container 900, with the heating fan 600 located above the heating unit 700. The reflector 400 is disposed at the top of the cooking cavity 120, and the heating fan 600 is located inside the reflector 400. The reflector 400 is provided with a hot air outlet 410, which is connected to the second air guide 221. The air guide shell 300 is arranged on the top of the reflector 400, the cold fan 500 is arranged between the air guide shell 300 and the reflector 400, the air guide shell 300 is provided with a cold air outlet 310, the cold air outlet 310 is connected to the first air guide port 211, and an air guide channel is formed between the reflector 400 and the air guide shell 300, and the air guide channel is connected to the first air guide port 211.

[0049] Among them, reference Figure 4 When the cooling fan 500 is in operation, the cooling airflow 510 flows in a first direction toward the external environment through the first air guide 211. Furthermore, when the heating fan 600 is in operation, the heating airflow 610 flows in a second direction toward a set position in the external environment through the second air guide 221. The first direction and the second direction intersect in a direction away from the exhaust port 110.

[0050] During operation, the cooling fan 500 and the heating fan 600 rotate synchronously. The cooling fan 500 generates a cold airflow 510 as it rotates. The cold airflow 510 flows along the air guide channel between the reflector 400 and the air guide housing 300 toward the first air guide port 211. After passing through the first air guide port 211, the cold airflow 510 is blown out in a first direction toward the external environment behind the air fryer. Simultaneously, the heating fan 600 generates a hot airflow 610 as it rotates. The hot airflow 610 flows into the cooking container 900 below it, and a portion of the hot airflow 610 flows along the reflector 400 toward the second air guide port 221 after passing through the cooking container 900. This portion of the hot airflow 610, after passing through the second air guide port 221, is blown out in a second direction toward the external environment behind the air fryer. Because the first direction and the second direction intersect in the environment behind the air fryer, after the hot air flow 610 and the cold air flow 510 are blown out from the rear side of the air fryer, the hot air flow 610 and the cold air flow 510 are mixed in the environment behind the air fryer, thereby effectively reducing the temperature of the hot air flow 610, thereby preventing the hot air flow 610 from scalding the user or overheating the obstruction behind the air fryer, such as a wall.

[0051] It should be noted that, in the present application, the cold air flow 510 is blown out from the first air guide port 211 in a first direction, and the cold air flow 510 is blown out from the second air guide port 221 in a second direction, and the hot air flow 610 and the cold air flow 510 are mixed in the external environment on the rear side of the air fryer. In this way, the mixing of the hot air flow 610 and the cold air flow 510 will not affect the exhaust effect of the air fryer on the hot air flow 610 and the cold air flow 510, thereby ensuring that the air fryer can discharge the cold air flow 510 and the hot air flow 610 generated in the air fryer in a timely manner, thereby ensuring the heat dissipation effect of the air fryer.

[0052] In addition, the air fryer controls the outward blowing direction of the hot air flow 610 and the cold air flow 510, thereby controlling the mixing of the hot air flow 610 and the cold air flow 510 in the external environment behind the air fryer. With this arrangement, the air fryer does not need to set up a more complex structure to achieve the mixing between the hot air flow 610 and the cold air flow 510. For example, the blowing direction of the hot air flow 610 and the cold air flow 510 can be controlled by controlling the orientation of the first air guide port 211 and the second air guide port 221. It can be seen that the present application not only satisfies the mixing of the hot air flow 610 and the cold air flow 510, but also ensures that the structure of the air fryer is relatively simple, thereby saving the manufacturing cost of the air fryer.

[0053] In some embodiments, reference Figure 2 and Figure 3The air fryer further includes a connecting base 800, which is disposed on the inner side of the air guide base 200 and is connected to the reflector 400 and the air guide housing 300. The air guide base 200 is provided with a first air guide channel 810 and a second air guide channel 820. One end of the first air guide channel 810 is connected to the cold air outlet 310, and the other end is connected to the first air guide port 211. One end of the second air guide channel 820 is connected to the hot air outlet 410, and the other end is connected to the second air guide port 221. It can be understood that through the setting of the air guide seat 200, the air guide seat 200 forms a first air guide channel 810, and the first air guide channel 810 can effectively guide the cold air flow 510 from the cold air outlet 310 to the first air guide outlet 211, so that it can be blown outward from the first air guide outlet 211 in a first direction, and the second air guide channel 820 can effectively guide the hot air flow 610 from the hot air outlet 410 to the second air guide outlet 221, so that it can be blown outward from the second air guide outlet 221 in a second direction.

[0054] It should be noted that, in the height direction of the air fryer, the first air guide port 211 is arranged higher than the second air guide port 221 , which will be described later.

[0055] In some embodiments, the second air guide 221 is used to discharge the hot air flow 610 vertically upward or obliquely upward to the external environment in a second direction relative to the height direction of the air fryer (see Figure 4 ).

[0056] It is understood that the first air duct 211 is used to discharge the cold air flow 510, and the second air duct 221 is used to discharge the hot air flow 610. The second air duct 221 is arranged lower than the first air duct 211. Therefore, the cold air flow 510 is located above the hot air flow 610 when it is blown out. The second direction is a vertically upward direction or an obliquely upward direction. That is, the hot air flow 610 is blown out in a vertically upward direction or an obliquely upward direction. With this arrangement, after the hot air flow 610 is blown out from the second air duct 221, it can be effectively mixed with the cold air flow 510 above it, thereby effectively reducing its own temperature. In addition, since the hot air flow 610 is blown upward, there is usually no obstruction above it, so the heat of the hot air flow 610 is more easily dissipated into the external environment. At the same time, the hot air flow 610 also avoids obstructions on the rear side, effectively reducing the heating of the rear obstructions, such as reducing the heating of the wall.

[0057] Furthermore, the angle between the height direction of the air fryer toward the top thereof and the second direction is set between 0° and 45°, or in other words, the upward blowing angle of the hot air flow 610 is set between 45° and 90°. For example, the upward blowing angle of the hot air flow 610 is set to 45°, 50°, 60°, 70°, 80°, or 90°. It is understood that the upward blowing angle of the hot air flow 610 is set between 45° and 90°. In this way, the upward blowing angle of the hot air flow 610 is large enough that the hot air flow 610 can quickly mix with the cold air flow 510 above it after being blown out of the air fryer, thereby reducing its own temperature and preventing the hot air flow 610 from not mixing with the cold air flow 510 in time.

[0058] In some embodiments, the first air guide 211 is used to allow the cold air flow 510 to be discharged upward to the external environment in a first direction relative to the height direction of the air fryer, and the upward angle of the second direction is greater than the upward angle of the first direction, so that the first direction and the second direction intersect in the direction away from the air outlet 110 (refer to Figure 4 ).

[0059] It will be appreciated that the first direction is an upward, oblique direction, and accordingly, the direction in which the cold airflow 510 is blown outward is an upward, oblique direction. Simultaneously, the second direction is a vertical or upward, oblique direction, and accordingly, the direction in which the hot airflow 610 is blown outward is a vertical or upward, oblique direction. Because the upward angle of the second direction is greater than the upward angle of the first direction, the hot airflow 610 and the cold airflow 510, after being blown out of the air fryer, mix in the external environment behind the air fryer, thereby reducing the temperature of the hot airflow 610. Furthermore, because both the hot airflow 610 and the cold airflow 510 are blown outward in an upward direction, this configuration allows the hot airflow 610 and the cold airflow 510 to mix effectively, thereby reducing the temperature of the hot airflow 610.

[0060] Furthermore, the angle between the height direction of the air fryer toward the top and the first direction is set between 30° and 60°. In other words, the upward blowing angle of the cold air flow 510 is set between 30° and 60°. For example, the upward blowing angle of the cold air flow 510 is set to 30°, 40°, 50°, or 60°. It is understood that the upward blowing angle of the cold air flow 510 is set between 30° and 60°, that is, the upward blowing angle of the cold air flow 510 is not less than 30 degrees. In this configuration, the upward blowing angle of the cold air flow 510 is large enough to effectively mix with the hot air flow 610, thereby reducing the temperature of the hot air flow 610. At the same time, the upward blowing angle of the cold air flow 510 is not greater than 60 degrees. In this configuration, the upward blowing angle of the cold air flow 510 is small enough to quickly mix with the hot air flow 610 after exiting the air fryer, thereby reducing the temperature of the hot air flow 610.

[0061] In another possible embodiment, the first air guide 211 is used to discharge the cold air flow 510 horizontally outward to the external environment in a first direction relative to the height direction of the air fryer (refer to Figure 5 ). It can be understood that the first air guide port 211 is located directly above the second air guide port 221, and accordingly, the cold air flow 510 is located above the hot air flow 610. Therefore, the hot air flow 610 adopts a vertical or inclined upward blowing direction, and the cold air flow 510 adopts a horizontal outward blowing direction. With this arrangement, when the hot air flow 610 passes directly in front of the first air guide port 211, the blown cold air flow 510 mixes with the hot air flow 610, thereby quickly reducing the temperature of the hot air flow 610. In addition, the air guide base 200 does not need to be provided with a more complex structure to control the flow direction of the cold air flow 510, and the structure of the air guide base 200 is relatively simple.

[0062] In other possible embodiments, the first air guide 211 is used to allow the cold air flow 510 to be discharged downwardly to the external environment in a first direction relative to the height direction of the air fryer (see Figure 6 ). It can be understood that the first air guide port 211 is located directly above the second air guide port 221, and accordingly, the cold air flow 510 is located above the hot air flow 610. Therefore, the hot air flow 610 adopts a vertical or upward blowing direction, and the cold air flow 510 adopts a downward blowing direction. With this arrangement, the hot air flow 610 can quickly mix with the cold air flow 510 blown out of the air fryer after being blown out of the air fryer, thereby reducing the temperature of the hot air flow 610. Among them, the first air guide port 211 and the second air guide port 221 are close to each other in vertical position. Therefore, the hot air flow 610 and the cold air flow 510 are mixed at a position close to the housing 100, thereby effectively avoiding the hot air flow 610 from scalding the user.

[0063] In some embodiments, reference Figures 2 to 4 The air guide base 200 is generally L-shaped and includes a first air guide rib 210 and a second air guide rib 220 connected to each other. The first air guide ribs 210 are arranged at intervals along the height of the air fryer, and the second air guide ribs 220 are connected to the lower ends of the first air guide ribs 210 and extend outward relative to the first air guide ribs 210. A plurality of first air guide ports 211 are spaced apart on the first air guide ribs 210, and a plurality of second air guide ports 221 are spaced apart on the second air guide ribs 220.

[0064] It can be understood that the air guide seat 200 adopts such a structural form, the first air guide ribs 210 are arranged at approximately vertical intervals, and the first air guide outlet 211 with a smaller upward inclination angle can be easily set, for example, the first air guide outlet 211 with an inclination angle of between 30° and 60° is set on the first air guide rib 210; and the second air guide ribs 220 are arranged to extend approximately horizontally, and the second air guide outlet 221 with a larger upward inclination angle can be easily set, for example, the second air guide outlet 221 with an inclination angle of between 45° and 90° is set on the second air guide rib 220. It can be seen from the above that the design of the air guide seat 200 facilitates the mixing of the hot air flow 610 and the cold air flow 510.

[0065] In order to enable the hot air flow 610 to be discharged vertically or obliquely upward to the external environment through the second air guide outlet 221, the inner side wall of the second air guide outlet 221 away from the first air guide rib 210 is a first air guide surface 2211, or in other words, the second air guide rib 210 has a first air guide surface 2211 facing the side of the cold air outlet 310, and the first air guide surface 2211 extends vertically or obliquely upward. In this way, after the hot air flow 610 flows into the second air guide outlet 221, the first air guide surface 2211 guides the hot air flow 610 vertically or obliquely upward, so that the hot air flow 610 is discharged vertically or obliquely upward to the external environment through the second air guide outlet 221.

[0066] Furthermore, the inner sidewall of the second air guide vent 221 near the first air guide rib 210 is a second air guide surface 2212. In other words, the second air guide rib 210 is provided with a second air guide surface 2212 on the side facing away from the first air guide surface 2211. The second air guide surface 2212 extends upward at an angle, and the upward inclination angle of the first air guide surface 2211 is greater than the upward inclination angle of the second air guide surface 2212. In this configuration, the cross-section of the second air guide vent 221 gradually decreases from the inside to the outside of the housing 100. It is understood that the provision of the second air guide surface 2212 can accelerate the flow velocity of the hot air flow 610 in the second air guide vent 221, thereby allowing the hot air flow 610 to be quickly discharged into the external environment.

[0067] Furthermore, the second air guide rib 220 is provided with an upwardly protruding baffle portion 222. The baffle portion 222 is located on the side of the second air guide opening 221 away from the first air guide rib 210. The side of the baffle portion 222 near the second air guide opening 221 is smoothly connected to the first air guide surface 2211 and extends vertically or obliquely upward in the second direction. It can be understood that after the hot air flow 610 is accelerated by the second air guide opening 221 and flows toward the baffle portion 222, the hot air flow 610 is guided by the baffle portion 222 and blown vertically or obliquely upward along the second direction, thereby mixing with the cold air flow 510 above it, thereby reducing its own temperature.

[0068] In order to achieve the cold air flow 510 being blown out from the first air guide port 211 of the housing 100 in the first direction, in some embodiments, the side walls of the first air guide port 211 away from and close to the second air guide rib 220 are both extended upwardly and obliquely in the first direction. In this way, the first air guide port 211 guides the hot air flow 610 in an obliquely upward direction, that is, the first direction mentioned above. Therefore, when the cold air flow 510 generated by the cold fan 500 is blown out from the first air guide port 211, the first air guide port 211 guides the incoming cold air flow 510 to be blown out obliquely upwardly in the first direction, so that it can be better mixed with the hot air flow 610.

[0069] In some embodiments, the first air guide 211 is used to allow the cold air flow 510 to be discharged downwardly in a first direction relative to the height direction of the air fryer to the external environment; at the same time, the second air guide 221 is used to allow the hot air flow 610 to be discharged horizontally outward in a second direction relative to the height direction of the air fryer to the external environment (refer to Figure 7 ).

[0070] It is understood that the cold air flow 510 is blown out from the first air guide 211 in a first direction, obliquely downward, and the hot air flow 610 is blown out from the second air guide 221 in a second direction, horizontally outward. In this arrangement, the cold air flow 510 cools the hot air flow 610 when passing directly in front of the second air guide 221. With this cooling method, the hot air flow 610 is promptly cooled by the cold air flow 510 when it flows toward the obstruction behind it, thereby preventing the hot air flow 610 from excessively heating the obstruction behind it.

[0071] In some embodiments, the first air guide 211 is used to allow the cold air flow 510 to be discharged downwardly to the external environment in a first direction relative to the height direction of the air fryer, and the second air guide 221 is used to allow the hot air flow 610 to be discharged downwardly to the external environment in a second direction relative to the height direction of the air fryer; wherein the downward inclination angle of the first direction is greater than the downward inclination angle of the second direction, so that the first direction and the second direction intersect in the direction away from the exhaust port 110 (refer to Figure 8 ).

[0072] It is understood that the first air duct 211 is used to discharge the cold air flow 510, and the second air duct 221 is used to discharge the hot air flow 610. The second air duct 221 is arranged lower than the first air duct 211. Therefore, when the cold air flow 510 is blown out, it is located above the hot air flow 610. Because the first direction and the second direction are both inclined downward, and the downward inclination angle of the first direction is greater than the downward inclination angle of the second direction, the hot air flow 610 and the cold air flow 510 are both blown out in a downward direction. The hot air flow 610 and the cold air flow 510 can be preferably mixed during the downward flow process, thereby effectively reducing the temperature of the hot air flow 610.

[0073] The present application discloses an air fryer, comprising a shell 100 and an air guide seat 200, wherein the shell 100 is provided with an exhaust port 110 communicating with the external environment, and a cooking cavity 120 is provided in the shell 100; the air guide seat 200 is arranged at the exhaust port 110, and the air guide seat 200 is provided with a first air guide port 211 and a second air guide port 221 communicating with the external environment; the air guide shell is provided with a cold air outlet 310, which is communicated with the first air guide port 211, and the cooking cavity 120 is provided with a hot air outlet 410, which is communicated with the second air guide port 221; when the air fryer is in operation, the cold air flow 510 flows in a first direction toward the external environment at the first air guide port 211; the hot air flow 610 flows in a second direction toward the external environment at the second air guide port 221, and the first direction and the second direction intersect in a direction away from the exhaust port 110.

[0074] It can be understood that the cold air flow 510 is blown out from the first air guide port 211 in a first direction, and the cold air flow 510 is blown out from the second air guide port 221 in a second direction, and the hot air flow 610 and the cold air flow 510 are mixed in the external environment on the rear side of the air fryer. In this way, the mixing of the hot air flow 610 and the cold air flow 510 will not affect the exhaust effect of the air fryer on the hot air flow 610 and the cold air flow 510, thereby ensuring that the air fryer can discharge the cold air flow 510 and the hot air flow 610 generated in the air fryer in time, thereby ensuring the heat dissipation effect of the air fryer.

It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
