Description

an air fryer

technical field

The invention belongs to the field of household kitchen appliance manufacturing, and in particular relates to an air fryer which simultaneously utilizes heat radiation and hot air flow to bake food.

Background technique

As shown in Figure 1, the existing air fryer usually has a raised air guide on the bottom wall of the inner pot, such as in Chinese patent ZL200880131179. At the bottom of the food baking chamber of the pot body 1, the frying basket 3 is arranged in the inner container 2, and an electric heating tube 4 and a fan 5 located above the frying basket 3 are also arranged above the frying basket 3. The side wall of the frying basket 3 It is a flat plate 30, the bottom is a grid plate 31, an air flow channel 6 is provided between the inner tank 2 and the frying basket 3, and there is at least one guide body 9 in a complex convex-concave shape at the center of the inner tank bottom. Although the fryer has the function of guiding the airflow to converge upwards so that the food in the fryer basket 3 is heated evenly, the forming process of the guide body with the convex and concave shape of the bottom of the pot is complicated, the manufacturing cost is high, and it is not easy to clean the bottom of the pot.

Contents of the invention

The object of the present invention is to overcome the problems existing in the existing air fryer, and provide an air fryer with uniform heating and favorable heating effect in the middle.

The technical solution to achieve the purpose of the present invention: an air fryer, including a pot body 1, an inner tank 2, a frying basket 3 disposed in the inner tank 2, an electric heating tube 4 located above the frying basket 3 and an electric heating tube located 4, the fan 5 above, the side wall of the frying basket 3 is a thin plate, the bottom is a grid, and an air flow channel 6 is arranged between the inner tank 2 and the frying basket 3, and it is characterized in that: the outer periphery of the bottom of the frying basket 3 faces The lower extension forms the guide cylinder 7 with a large upper opening and a small structure with a lower opening, and the side wall of the lower part of the guide cylinder 7 is provided with evenly distributed air intake oblique holes 8 that rotate the airflow.

The air intake slant hole 8 is a slit hole in the same direction to the left or right.

The guide tube 7 is a cylinder connected to the bottom side wall of the frying basket 3 .

The guide tube 7 is supported on the bottom wall of the inner tank 2 .

The frying basket 3 is movably socketed on the guide tube 7 .

Beneficial effects of the present invention: since the outer periphery of the bottom of the frying basket extends downwards to form a guide tube, and the side wall of the guide tube is provided with a guide hole for rotating the air flow, this structure does not need to be set on the inner tank Complicated guide body, the processing technology is simpler, the manufacturing cost is lower, and the bottom of the inner tank is easier to clean. Cooperating with the suction of the fan, the hot air flowing through the air guide tube rotates more powerfully and rushes upwards through the bottom hole of the frying basket, penetrating the gap between the food, so that the food is evenly heated; the air guide tube is supported by the bottom of the liner On the wall, the handle mainly plays a positioning role. Compared with the single-point positioning of the handle, the suspension is stressed, the support of the frying basket is more stable, and the food is heated more evenly.

detailed description

The specific implementation of the air fryer of the present invention will be further described in detail below in conjunction with the accompanying drawings.

Embodiment 1: As shown in Figure 2 and Figure 3, the air fryer of this embodiment has an inner container 2 as a food baking chamber in the pot body 1, and a frying basket 3 for loading food is arranged in the inner container 2. An electric heating tube 4 and a fan 5 located above the electric heating tube 4 are also arranged above the frying basket 3. The side wall of the frying basket 3 is a thin plate, and the bottom is a grid, forming an airflow channel 6 between the inner tank 2 and the frying basket 3 , in order to facilitate airflow circulation and stable support, a cylindrical guide tube 7 extends downward from the outer periphery of the bottom of the frying basket 3, and the lower end of the guide tube 7 is preferably directly supported on the bottom wall of the liner 2. The gap between them is as small as possible, and the side wall of the guide tube 7 is provided with an air intake slant hole 8, and the food gap in the middle of the frying basket 3 is usually smaller. In order to improve the air flow mixing effect, the air intake slant hole 8. It is designed as a tangential slit hole facing left or right in the same direction, preferably at an angle of 60 degrees with the bottom surface. After punching with a metal sheet, the side flows along the air flow to the hem to form a wind guide vane to guide the air flow to rotate. The sum of the flow area of the air intake inclined holes 8 on the guide tube is smaller than the flow area of the air flow channel 6, so the air flow speeds up after passing through the air intake holes, and with the cooperation of the suction force of the upper fan, the air flow that rotates upwards is more concentrated , so as to achieve uniform heating of the food in the frying basket from bottom to top.

Embodiment 2: As shown in Figure 4, the main structure of the air fryer of this embodiment is basically the same as that of Embodiment 1, the difference is that the support body 7 has a structure with a large opening at the upper end and a small opening at the lower end. With the structure of the guide tube 7, the airflow flows more smoothly, and the swirling airflow guided by the air intake inclined hole 8 spreads upward faster.

Embodiment 3: As shown in FIG. 5 , the main structure of the air fryer of this embodiment is basically the same as that of Embodiment 1. The difference is that the guide tube 7 has a large opening diameter at the upper and lower ends and a relatively small diameter at the middle. structure, the air inlet slant hole 8 is opened on the side wall of the lower part of the air guide tube 7, and the guide tube 7 with this structure is conducive to accelerating the airflow velocity in the small diameter of the middle part, thereby improving the airflow through the bottom of the frying basket 3 and penetration of food crevices.

A further advantage is that the side wall of the deflector tube extends upwards to be movably socketed with the frying basket 3, and the side wall and the bottom wall of the frying basket 3 can be integrally formed by grids, which will significantly reduce the overall weight of the frying basket 3. It is more convenient and labor-saving to take.
