The air fryer not only can cook food materials into a crisp taste similar to fried chicken wings, but also can avoid the defect of excessive oil intake of human bodies caused by frying the chicken wings.

However, the existing air fryer has the following defects when cooking food materials: because the overall dimension of the food material has a change of size, and the position of the hot air assembly in the upper cover assembly is fixed, therefore, when the cooking height is small or a small amount of food material is used, the distance between the hot air assembly and the food material is too far, and the high-temperature air flow blown out by the hot air assembly can be cooled on the way, so that the cooking speed and the cooking efficiency of the hot air assembly on the food material can be reduced. Certainly, we can properly reduce the height of the fryer and then reduce the distance between the steaming grill and the hot air assembly, but when the cooking height is larger or a large amount of food materials are encountered, the distance between the food materials and the hot air assembly is too short, and the food materials are heated unevenly, one side of the food materials close to the steaming grill is not baked yet, and one side of the food materials close to the hot air assembly is baked.

The air flow with the temperature reduced after the food is heated flows upwards from the middle of the cooking cavity through the steaming grill, is sucked by the uniform heating fan from the middle of the upper cover assembly, flows downwards again after being heated by the heating tube and heats the cooked food, and then high-temperature air flow flowing circularly is formed in the cooking cavity.

In addition, we can set up the altitude mixture control structure who is used for adjusting to evaporate gridion and hot-blast subassembly distance between steaming and roasting frame and the frying pan to make the user can according to the height dimension of eating the material or eat how much of material volume, make through the altitude mixture control structure evaporate and roast the frame and adjust to suitable height, under the prerequisite that effectively promotes hot-blast subassembly and cook efficiency to eating the material, ensure the thermally equivalent of eating the material, avoid eating the material phenomenon that the maturity is uneven.

It should be noted that the height adjusting structure can be a telescopic rod arranged on the lower side of the steaming and baking frame, and the distance between the steaming and baking frame and the hot air component can be conveniently adjusted by changing the length of the telescopic rod. That is to say, the utility model discloses creatively be applied to current altitude mixture control structure and evaporate the gridion, make to evaporate the gridion under the prerequisite that maintains current functional effect, promoted the application scope of different kinds of edible materials greatly to better culinary art effect has.

When the food materials are small in size and small in number (the instant food materials are easy to cook), the steaming and baking rack can be close to the hot air assembly as much as possible, so that the fast cooking of the food materials is facilitated, and meanwhile the uniform heating of the food materials can be guaranteed. That is, the height adjusting structure at this time makes the steaming rack have a higher height. On the contrary, when the food materials are large in size and large in quantity (the instant food materials are not easy to cook), the steaming and baking frame can be far away from the hot air assembly as far as possible, so that the food materials can be uniformly heated, and the phenomenon of uneven cooking is avoided. That is, we can change the height of the cooking grill by the height adjusting structure so as to keep the proper cooking distance between the highest position of the food material and the hot wind assembly.

As a preferable scheme, as shown in fig. 2 and fig. 3, the height adjusting structure comprises supporting legs 5 rotatably arranged at the edge of the steaming and baking rack, when the supporting legs are rotated inwards to be positioned at the lower side of the steaming and baking rack, the supporting legs are in a contracted position, the steaming and baking rack can be conveniently placed at the bottom of the fryer, so that the distance between the steaming and baking rack and the hot air assembly is furthest, and the steaming and baking rack is suitable for cooking food materials with higher height or more quantity; when the supporting legs rotate outwards to be far away from the steaming grill, the supporting legs are located at the supporting positions, the end parts of the supporting legs which rotate to the supporting positions are supported on the inner side wall of the middle part of the frying pan, so that the steaming grill has a higher height, and the distance between the steaming grill and the hot air assembly is close to the end parts of the supporting legs, so that the steaming grill is suitable for cooking food materials with lower height or less quantity.

Of course, a rotation limiting structure should be arranged between the supporting legs and the steaming and baking frame so as to position the supporting legs at the contraction position or the supporting position. In addition, the rotation limiting structure can enable the supporting legs to have a plurality of positioning angles when the supporting legs rotate outwards, so that the supporting legs have a plurality of supporting positions, the steaming and roasting rack can be supported on different heights of the fryer, and the fine adjustment of the height of the steaming and roasting rack is realized.

Furthermore, the fryer is square, positioning steps 21 with large upper parts and small lower parts can be arranged at four corners of the inner side of the fryer, and the end parts of the supporting legs which are rotated to the supporting positions can be supported on the positioning steps. Certainly, more than or equal to two positioning steps can be arranged at intervals, and the rotation limiting structure enables the supporting legs to be positioned at a plurality of different positioning angles when the supporting legs rotate outwards, so that the end parts of the supporting legs can be supported and positioned in the positioning steps with different heights.

As another preferred scheme, as shown in fig. 4, the height adjusting structure includes a supporting column 6 with one end connected to the lower side of the steaming grill and the length of the supporting column is adjustable, and the supporting columns can be respectively arranged at four corners of the lower side of the steaming grill, so that the steaming grill can be stably supported at different heights by adjusting the length of the supporting column, and the cooking requirements of different food materials can be met.

Specifically, the support column can adopt a telescopic rod, or the support column comprises a first column body 61 and a second column body 61, wherein the upper end of the first column body is connected to the lower side of the steaming and baking frame, and one end of the second column body is hinged with the lower end of the first column body, so that the support column forms a folding structure.

Thus, when the first column is fixedly connected with the steaming and baking frame, if the second column is rotated towards the steaming and baking frame to be close to the steaming and baking frame, the steaming and baking frame can be supported on the bottom wall of the fryer through the first column, and the steaming and baking frame has a first lower height; when the second cylinder is rotated downwardly away from the cooking grill, the cooking rack is supported on the bottom wall of the fryer by the first and second cylinders, and the cooking rack has a second, higher height. Through rationally designing the length of first cylinder and second cylinder, can make steaming and baking frame have different supporting height to the culinary art of adaptation different height food.

Of course, it is necessary to provide a corresponding rotation limiting structure between the first cylinder and the second cylinder, so that when the grill is at the second height, the second cylinder can rotate to form an included angle of 185 ° -195 ° with the first cylinder, and the second cylinder is positioned relative to the first cylinder by the rotation limiting structure, so that the second cylinder forms a "dead point" with respect to the first cylinder, thereby ensuring the reliable positioning of the second cylinder.

That is, the first column and the second column can have approximate lengths; alternatively, the second leg may be longer than the first leg to provide the cooking rack with a first height closer to the bottom wall of the fryer and a second higher height, although the second leg and the first leg may form an L-shape when the cooking rack is at the second height, i.e., the angle between the second leg and the first leg may be between 75 and 85 to avoid the longer second leg from contacting the underside of the cooking grill.

It will be appreciated that the support column may also include a third column that is hinged to the second column to provide multiple heights to the grill.

As is known, the inner side wall of the fryer is usually provided with a non-stick coating, and for this purpose, an elastic foot pad 7 made of silicone rubber can be respectively arranged at the middle position of four edges of the steaming and baking frame, and specifically, a downward extending surrounding edge 41 can be arranged at the edge of the steaming and baking frame, so as to improve the strength and the rigidity of the steaming and baking frame and avoid the twisting and deformation of the steaming and baking frame. Then set up mounting hole 411 on the surrounding edge, the elasticity callus on the sole includes columniform supporting part 71, and a body coupling is at the spliced pole 72 of supporting part tip, and spliced pole interference fit is in the mounting hole to can avoid supporting legs contact fryer diapire effectively and destroy the non-stick coating of fryer diapire. That is, the steaming and baking rack is supported on the bottom wall of the fryer by the elastic foot pad, thereby being beneficial to stabilizing the height of the steaming and baking rack. Of course, we should have the lowest point of the support foot that is turned inward to the retracted position higher than the lowest point of the resilient foot pad.

Furthermore, a second clamping groove 412 can be arranged on the surrounding edge corresponding to the position of the supporting foot. Therefore, the supporting legs which are rotated outwards to the supporting positions can be clamped in the second clamping grooves, so that the supporting legs are prevented from rotating downwards to be in a vertical state.

Furthermore, clamping ribs 42 which are arranged oppositely can be arranged on the lower side of the steaming and baking frame close to the supporting feet, clamping protrusions 421 are arranged at the end parts of the opposite sides of the clamping ribs, so that a first clamping groove 422 is formed between the two opposite clamping protrusions, and the supporting feet which rotate inwards to the contraction position are clamped in the first clamping groove.

It is known that the steaming and baking frame can be manufactured by sheet metal process, and correspondingly, the clamping rib sheet with the clamping protrusions can be integrally formed with the steaming and baking frame in a punch forming mode, so that the production efficiency is improved, and the supporting legs can be stably clamped at the contraction position.

Especially, the relative tip of one side of screens muscle piece is equipped with the screens arch, that is to say, the thickness of two screens muscle pieces is located the coplanar, and the side of screens muscle piece is relative to be favorable to guaranteeing the intensity and the rigidity of screens muscle piece, avoid the supporting legs card to take place bending deformation in the screens muscle piece when going into first draw-in groove. In addition, the screens are protruding can be die-cut shaping with screens muscle piece integratively, avoid forming first draw-in groove through technologies such as bending, make things convenient for its processing design.

In order to facilitate the rotary connection of the supporting legs and the steaming and baking frame, supporting ribs 43 which are arranged oppositely can be arranged on the steaming and baking frame close to the supporting legs, rotating holes are coaxially formed in the supporting ribs, the supporting legs are bent into a U shape by stainless steel wires, and two ends of each U-shaped supporting leg are integrally bent outwards to form connecting ends which are rotatably connected in the corresponding rotating holes.

As mentioned above, the supporting rib can be formed by stamping with the steaming and baking frame through sheet metal process, specifically, a fabrication hole can be provided on the steaming and baking frame, and one side edge of the fabrication hole is integrally bent and extended downwards to form the supporting rib. Because the supporting ribs and the supporting legs have certain elasticity, when the supporting legs are required to be assembled in the rotating holes of the supporting ribs, the supporting legs can be inwards extruded, and when the two connecting ends of the supporting legs are squeezed between the supporting ribs which are oppositely arranged, the supporting ribs can be outwards bent and spread. When the supporting legs are installed in place, the supporting ribs are elastically reset inwards, the supporting legs are reset outwards, the connecting ends can be rotatably connected into the rotating holes of the supporting ribs at the moment, the connecting ends of the supporting legs can be effectively prevented from being separated from the rotating holes, and therefore the supporting legs are convenient to assemble.

Certainly, the silica gel protective sleeve 51 can be sleeved outside the supporting leg, so that the supporting leg at the supporting position can be prevented from scraping steps on the inner side of the fryer. In particular, the protective sleeve sleeved on the supporting leg is convenient to detach and update.

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