Description

Technical Field

[0001] The invention relates to the field of manufacturing and processing of kitchen appliances, and in particular to a frying basket assembly of an air fryer and the air fryer. Background Art

[0002] An air fryer is a kitchen appliance that uses an air heating component and the hot circulating airflow it generates to bake food. The air heating component is used to heat the air in the frying basket to make the air reach the temperature for frying food, and to form a circulating airflow in the frying basket to evenly heat the food in the frying basket, dehydrate the surface of the food, and form a fried taste.

[0003] When the air fryer is frying food, the solid fat in the food will be liquefied by heat and separated from the food. If the separated fat comes into contact with the high-temperature air heating component, a lot of oil smoke will be generated. Studies have found that when the oil temperature reaches the smoking point of edible oil, 170 degrees, blue smoke will appear at the initial decomposition of the oil. As the temperature continues to rise, the decomposition speed will accelerate. When the oil temperature reaches 250 degrees, a lot of oil smoke will appear with a pungent smell, which can easily have an adverse effect on human health.

[0004] In addition, the oil smoke and vaporized grease are carried by the hot circulating airflow in the air fryer, and are easily attached to the surface of the air heating component during long-term use. When combined with small particles such as dust or impurities in the air, it is easy to form a firm solid attachment layer on the surface of the air heating component. This solid attachment layer mixed with grease, oil smoke, dust and impurities will not only affect the heating efficiency of the air heating component, but also easily produce gas molecules that are harmful to the human body during the continuous direct heating process of the air heating component. The harmful gas molecules will be attached to the surface of the food with the hot circulating airflow and absorbed by the human body.

[0005] It is difficult for the air fryers currently on the market to eliminate oil smoke while avoiding the formation of a solid adhesion layer mixed with grease, oil smoke, dust, impurities and other substances on the surface of the air heating component, which can easily have an adverse effect on the health of users and consumers of fried products.

[0057] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. The description of the exemplary embodiments is merely illustrative and is in no way intended to limit the present invention and its application or use. The present invention can be implemented in many different forms and is not limited to the embodiments described herein. These embodiments are provided to make the present invention thorough and complete and to fully express the scope of the present invention to those skilled in the art. It should be noted that unless otherwise specifically stated, the relative arrangement of the parts and steps, the composition of the materials, the numerical expressions and the numerical values ​​set forth in these embodiments should be interpreted as being merely exemplary, rather than as limitations.

[0058] like Figure 1-5 As shown:

[0059] In one aspect of the present invention, a frying basket assembly of an air fryer is provided, comprising a frying basket body 1 and a food rack 2. The bottom surface of the frying basket body 1 comprises a plurality of first protruding structures 11 protruding upward, and the first protruding structures 11 are provided with first through holes 111. The food rack 2 is detachably arranged above the bottom surface of the frying basket body 1, and the food rack 2 comprises a plurality of second protruding structures 21 protruding upward, and the arrangement position of the second protruding structures 21 on the food rack 2 corresponds to the arrangement position of the first protruding structures 11 on the bottom surface of the frying basket body 1, and the second protruding structures 21 are provided with second through holes 211, and the projections of the second through holes 211 and the first through holes 111 in the direction perpendicular to the bottom surface of the frying basket body 1 do not overlap each other.

[0060] The present invention provides a food rack 2 on the bottom surface of the frying basket body 1, and provides an upwardly protruding second protruding structure 21 on the food rack 2, so that the food rack can be raised to avoid a high-temperature frying effect caused by too small a distance between the food and the bottom surface of the frying basket body 1 and too high a temperature at the bottom of the frying basket body 1. In addition, the second protruding structure 21 can also guide the grease and water separated from the food to separate from the food by virtue of its own height difference, so that the surface of the food is deoiled and dehydrated, and a crispy fried texture is obtained.

[0061] The plurality of first protruding structures 11 protruding upwardly provided on the frying basket body 1 can effectively guide the grease dripping onto the bottom surface of the frying basket body 1 by virtue of their own height difference. In addition, the first protruding structures 11 can also cooperate with the second protruding structures 21 provided on the food rack 2 to serve as a structural basis for providing the first through holes 111 and the second through holes 211 whose projections do not overlap with each other.

[0062] The first through hole 111 and the second through hole 211 whose projections do not overlap each other play at least the following roles:

[0063] Firstly, since the projections of the first through hole 111 and the second through hole 211 in the direction perpendicular to the bottom surface of the frying basket body 1 do not overlap with each other, it is difficult for the fat in the food to continuously pass through the food rack 2 and the bottom surface of the frying basket body 1 and drip onto the air heating assembly 6 below during the dripping process. Therefore, the present invention can effectively reduce the fumes generated by the direct contact between the fat and the high-temperature components, making the air fryer more environmentally friendly and healthy during use.

[0064] Secondly, although the projections of the first through hole 111 and the second through hole 211 do not overlap with each other, making it difficult for grease to pass through the food rack 2 and the bottom surface of the frying basket body 1, the hot air generated by the air heating assembly 6 is not restricted by this structure. Under the combined influence of its own low density and the blowing power of the fan 62 in the air heating assembly 6, the hot air can pass through the first through hole 111 from the air heating assembly 6 located below the frying basket body 1, and then pass through the second through hole 211 to flow through the surface of the food, thereby frying the food;

[0065] Thirdly, although the projections of the first through hole 111 and the second through hole 211 do not overlap each other, the flow rate of the hot air flowing through the frying basket body 1 and the food rack 2 can be reduced, so that the food can be air-fried more evenly and fully.

[0066] In addition, the food rack 2 of the present invention is detachably connected to the frying basket body 1 , which makes it convenient for the user to disassemble and clean the food rack 2 and the frying basket body 1 .

[0067] Preferably, if Figures 4-5 As shown, the first through hole 111 is opened on the top surface of the first protruding structure 11, the second through hole 211 is opened on the side wall of the second protruding structure 21, and the projection range of the top surface of the second protruding structure 21 along the vertical direction to the bottom surface of the frying basket body 1 covers the projection range of the top surface of the first protruding structure 11 along the vertical direction to the bottom surface of the frying basket body 1.

[0068] Since the first through hole 111 is opened on the top surface of the first protruding structure 11, and the projection range of the top surface of the second protruding structure 21 covers the projection range of the top surface of the first protruding structure 11, the first through hole 111 is blocked by the top surface of the second protruding structure 21 in a direction perpendicular to the bottom surface of the frying basket body 1, so that the grease released from the food arranged above the food rack 2 is difficult to drip from the first through hole 111.

[0069] The second through hole 211 is opened on the side wall of the second protruding structure 21, so that the hot air generated by the air heating component 6 can pass through the food rack 2 to heat the surface of the food. Moreover, if grease drips from the second through hole 211 located on the side wall of the second protruding structure 21, it will also fall into the side wall of the corresponding first protruding structure 11 and flow along the side wall of the first protruding structure 11 to between the first protruding structures 11, and will not flow to the top surface of the first protruding structure 11, thereby reducing the possibility of grease passing through the bottom surface of the frying basket body 1 and dripping onto the air heating component 6.

[0070] Preferably, if Figure 1-2 As shown, the shape of the first protruding structure 11 is similar to that of the second protruding structure 21 , and the top surfaces of the first protruding structure 11 and the second protruding structure 21 are in the shape of an elliptical track.

[0071] The above-mentioned elliptical runway shape means that the first protruding structure 11 and the second protruding structure 21 are in the shape of an elongated strip, and the two ends of the elongated strip in the length direction are in the shape of arcs protruding outward, so that the edges of the first protruding structure 11 and the second protruding structure 21 have an arc-shaped transition, thereby preventing food from being damaged by the sharp corners or sharp edges on the first protruding structure 11 and the second protruding structure 21 on the one hand, and preventing users from being cut by the sharp corners or sharp edges when cleaning the food rack 2 and the frying basket body 1 on the other hand.

[0072] Preferably, in order to make the first protrusion structure 11 and the second protrusion structure 21 evenly and closely spread on the bottom surface of the frying basket body 1 and the food rack 2 respectively, a plurality of first protrusion structures 11 are arranged side by side on the bottom surface of the frying basket body 1 at equal intervals along the width direction of the elliptical runway shape, and a plurality of second protrusion structures 21 are arranged side by side on the food rack 2 at equal intervals along the width direction of the elliptical runway shape.

[0073] In order to effectively collect the grease separated from the food and guided by the first protruding structure 11 and the second protruding structure 21, the frying basket assembly further includes a first oil guide groove 12 and a second oil guide groove 22. The first oil guide groove 12 is recessed downward along the bottom surface of the frying basket body 1 and is arranged around the outer periphery of the plurality of first protruding structures 11 arranged side by side. The second oil guide groove 22 is recessed downward along the bottom surface of the food rack 2 and is arranged around the outer periphery of the plurality of second protruding structures 21 arranged side by side.

[0074] Furthermore, the downwardly concave structure of the second oil guide groove 22 can also cooperate with the second protruding structure 21 to further increase the distance between the food placed above the second protruding structure 21 and the oil falling into the second oil guide groove 22, thereby effectively preventing the oil from contacting the food and causing the food to be soaked and fried, and reducing the oil attached to the surface of the food, making the produced food lower in oil and healthier.

[0075] In order to make the hot air generated by the air heating assembly 6 heat the food inside the frying basket body 1 more uniformly, preferably, Figure 1 , 4 As shown, the side wall of the frying basket body 1 includes a plurality of third protruding structures 13 protruding outward, and a third through hole 131 is provided on the lower side wall of the third protruding structure 13 .

[0076] The third protruding structure 13 protrudes outward relative to the side wall of the frying basket body 1, and the third through hole 131 is arranged on the lower side wall of the third protruding structure 13, so that the hot air that has not entered the inside of the frying basket body 1 from the first through hole 111 can be guided to the inside of the third protruding structure 13 through the third through hole 131 during the process of flowing along the outside of the side wall of the frying basket body 1, thereby generating a heated airflow directed from the side wall to the inside of the food in the frying basket body 1, so as to perform more sufficient and uniform air frying of the food.

[0077] Preferably, in order to realize the detachable connection of the food rack 2 relative to the frying basket body 1, as Figure 1 , 2 As shown, the frying basket assembly also includes a plurality of flexible pads 3, which are made of a high temperature resistant flexible material and are fixedly arranged on the side of the food rack 2, and are used to fix and limit the food rack 2 from above the food rack 2 when the food rack 2 is arranged above the bottom surface of the frying basket body 1, and the plurality of flexible pads 3 are evenly distributed relative to the circumference of the food rack 2.

[0078] The flexible pad 3 can be made of a high temperature resistant silicone material. When the food rack 2 is set at the bottom of the frying basket body 1, the flexible pad 3 fixedly set on the side of the food rack 2 can be clamped on the side wall of the frying basket body 1 to fix and limit the food rack 2. Since the food rack 2 will not be subjected to excessive force to separate from the frying basket body 1 during use, the flexible pad 3 made of flexible material can play a limiting role. When the food rack 2 needs to be taken out of the frying basket body 1, the user only needs to bend the deformed flexible pad 3 to conveniently release the connection between the flexible pad 3 and the frying basket body 1 and take out the food rack 2. In the process of reinstalling the food rack 2, the deformed flexible pad 3 is bent again to conveniently put the food rack 2 back again.

[0079] It can be seen that using the flexible pad 3 as the limiting structure of the food rack 2 can not only well complete the limiting and fixing function of the food rack 2, but also facilitate the taking and placing operations of the food rack 2, and can be used repeatedly for a long time, with high reliability and service life.

[0080] like Figures 6 to 13As shown, in another aspect of the present invention, an air fryer is provided, comprising a frying basket assembly according to any of the above embodiments, and the air fryer further comprises an inner cavity 4, a cover 5 and an air heating assembly 6. The inner cavity 4 is disposed inside the air fryer with an upward opening, and is used to place the frying basket assembly; the cover 5 is disposed to cover the opening of the inner cavity 4; and the air heating assembly 6 comprises a heating element 61, a fan 62 disposed below the heating element 61, and a motor 63 for driving the fan 62, wherein the fan 62 is located above the bottom surface of the inner cavity 4, and the motor 63 is located below the bottom surface of the inner cavity 4; wherein, when the frying basket assembly is placed inside the inner cavity 4, the heating element 61 is located below the bottom surface of the frying basket body 1, and the heating element 61 does not contact the bottom surface of the frying basket body 1.

[0081] Since the present invention places the air heating component 6 below the frying basket body 1, the low density of hot air can be used to make the hot air generated by the air heating component 6 fully heat the surface of the food from bottom to top. In contrast, if the air heating component 6 is placed above the frying basket body 1, it is difficult to ensure that the hot air flows through the food located at the bottom area of ​​the frying basket body 1. It can be seen that the present invention heats and fries the food more fully and evenly.

[0082] The heating element 61 is not in contact with the bottom surface of the frying basket body 1, so that the bottom of the frying basket body 1 can be prevented from heating up too quickly due to direct contact between the two, thereby causing the food near the bottom of the frying basket body 1 to burn.

[0083] like Figure 12-13 As shown, the cover 5 of the air fryer disclosed in the present invention can be raised and lowered, and when the cover 5 is raised, the air fryer disclosed in the present invention can be provided with an intermediate connecting ring between the cover 5 and the inner cavity 4, so as to achieve sealing between the cover 5 and the inner cavity 4 after the cover 5 is raised. The raised cover 5 makes the internal capacity of the air fryer larger, can increase the amount of food cooked at one time, and enables the air fryer to cook and process a larger volume of food as a whole.

[0084] In order to prevent the oil smoke and vaporized grease from being entrained by the hot circulating airflow in the air fryer during operation and adhering to the high-temperature components of the air heating component 6 to form a solid attachment layer mixed with grease, oil smoke, dust and impurities.

[0085] Preferably, the fan 62 is configured to suck air from its upper side and send air to its lower side or radially outward. A fourth through hole 14 is provided at a position of the bottom surface of the frying basket body 1 facing the fan 62, and a fifth through hole 23 is provided at a position of the food rack 2 facing the fan 62. The fourth through hole 14 and the fifth through hole 23 are interconnected and form a return air passage from the inside of the frying basket body 1 to the upper side of the fan 62; and the heating element 61 includes a heating tube 611 and a porous plate 612. The heating tube 611 is in a spiral winding shape with the rotating shaft of the fan 62 as the center, and the upper side of the fan 62 is at least partially exposed in the central area of ​​the heating tube 611; and the porous plate 612 is fixedly arranged in the central area of ​​the heating tube 611.

[0086] The following is a specific description of how the high-temperature components of the air heating assembly 6 of the present invention are not prone to form a solid adhesion layer:

[0087] Since the fan 62 inhales air from its upper side and sends air to its lower side or radially outward, an air circulation is formed inside the air fryer, where air enters from the first through hole 111 and the third through hole 131, and air is discharged from the fourth through hole 14 provided at the bottom surface of the frying basket body 1 directly facing the fan 62. It can be seen that the hot air for air frying food, that is, the hot circulating airflow that easily carries oil smoke and vaporized fat, will leave the frying basket body 1 from the fourth through hole 14 and flow to the upper side of the fan 62. Since the air heating component 6 is disposed between the fan 62 and the bottom of the frying basket body 1, the hot air that leaves the frying basket body 1 from the fourth through hole 14 and flows to the upper side of the fan 62 will inevitably pass through the air heating component 6.

[0088] In this regard, Figure 6 As shown, the upper side of the fan 62 of the present invention is at least partially exposed to the central area of ​​the heating tube 611, and a porous plate 612 is arranged in the center of the spirally coiled heating tube 611, so that the heating tube 611 with a higher temperature does not directly contact the hot air leaving the frying basket body 1 from the fourth through hole 14 and flowing to the upper side of the fan 62, thereby reducing the solid adhesion layer formed on the surface of the heating tube 611.

[0089] In contrast, if the air heating component 6 is disposed above the opening of the frying basket body 1, it is difficult to guide the hot air circulation, and it is difficult to keep the hot circulating airflow that may carry oil smoke and vaporized grease away from the high-temperature components of the air heating component 6. As a result, a solid adhesion layer is easily generated on the surface of the high-temperature components of the air heating component 6, which has an adverse effect on the thermal efficiency of the air fryer and the health of the user.

[0090] Preferably, the food rack 2 further includes a lifting ring 15, which can facilitate the user to take the food rack 2 out of the frying basket body 1. The lifting ring 15 is installed inside the fifth through hole 23, and can rotate relative to the plane where the fifth through hole 23 is located. When the lifting ring 15 is rotated to be parallel to the plane where the fifth through hole 23 is located, the lifting ring 15 is embedded in the fifth through hole 23, so that when the lifting ring 15 is not needed, the lifting ring 15 can be rotated to be coplanar with the fifth through hole 23, so as not to interfere with the food placed on the food rack 2.

[0091] Since the air heating assembly 6 of the present invention is arranged on the lower side of the frying basket body 1, preferably, the air fryer disclosed in the present invention can also have frying, roasting and stewing functions.

[0092] like Figures 7 to 9 As shown, the air fryer also includes a grilling assembly 7, including a grilling tray 71 and handles 72 located on both sides of the grilling tray 71 and inclined inwardly, the upper surface of the grilling tray 71 is provided with a plurality of fourth protrusion structures 73 protruding upward, and the fourth protrusion structures 73 extend radially outward relative to the center of the grilling tray 71, and the lower surface of the grilling tray 71 is provided with a plurality of grooves 74, and when the grilling assembly 7 is placed inside the inner cavity 4, the heating tube 611 is embedded inside the groove 74.

[0093] The inwardly inclined handle 72 can facilitate the user to grasp, take or place the baking tray 71, and the fourth protrusion structure 73 provided on the upper surface of the baking tray 71 can make the food heat more evenly, separate the grease from the food better, and make the food less likely to stick to the baking tray 71. The groove 74 provided on the lower surface of the baking tray 71 can be embedded with the heating tube 611, which can make the connection between the baking tray 71 and the heating tube 611 more stable on the one hand, and can make the heat transfer efficiency of the heating tube 611 to the baking tray 71 higher on the other hand.

[0094] like Figures 10-11 As shown, the air fryer further includes a stewing component 8 , including a stewing pot 81 , and when the stewing component 8 is placed inside the inner cavity 4 , the bottom surface of the stewing pot 81 is attached to the upper surface of the heating tube 611 .

[0095] Therefore, the present invention can reduce the oil smoke generated by the air fryer by preventing the oil precipitated from the food from directly dripping onto the air heating component 6 and effectively guiding the precipitated oil. The present invention prevents the hot air that has heated the food and refluxed from directly flowing through the surface of the air heating component 6, thereby reducing the formation of a solid adhesion layer mixed with substances such as oil, oil smoke, dust and impurities on the surface of the air heating component 6, thereby protecting the health of users and consumers of fried products. In addition, the present invention can also enrich the functions of the air fryer by arranging the air heating component 6 at the bottom, thereby realizing food processing methods such as frying, roasting, and slow cooking.

[0096] So far, some specific embodiments of the present invention have been described in detail by way of examples, but those skilled in the art should understand that the above examples are for illustration only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that the above embodiments may be modified or some technical features may be replaced by equivalents without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
