Abstract
Description
Technical Field
[0001] This utility model relates to the field of air fryer technology, specifically to an air inlet cover for an air fryer. Background Technology
[0002] An air fryer is a cooking appliance that uses rapidly circulating hot air inside to heat and bake food. It uses hot air instead of the hot oil in a frying pan to cook the food; at the same time, the hot air blows away the surface moisture of the food, giving it a similar effect to deep-frying. Because it uses air as a heat transfer medium, it can effectively reduce the oil content of food, providing people with healthier diets, and is therefore increasingly used by consumers.
[0003] The air fryer has an inner top cover that divides the interior into an upper and lower chamber. The motor, control module, and other components are located in the upper chamber, while the circulating fan, heating element, and pot body are located in the lower chamber. An air inlet connected to the upper chamber is located on the outer wall of the air fryer, and an air intake hole is located on the inner top cover. Air can enter the lower chamber through the air inlet, upper chamber, and air intake hole, and is circulated rapidly by the circulating fan. To improve air intake efficiency, an air intake fan is also installed in the upper chamber, covered by an air intake shroud, forming an air intake chamber within the shroud. However, due to limitations in the shape and size of the air intake hole on the inner top cover, the air intake efficiency of the dual fans (air intake fan and circulating fan) is still insufficient for large-capacity air fryers, thus affecting the cooking efficiency. Therefore, how to further improve the air intake efficiency of the air shroud has become an urgent problem to be solved. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an air fryer air inlet cover that can further improve air intake efficiency.
[0005] The technical solution of this utility model is to provide an air inlet hood for an air fryer with the following structure: The device includes a fan cover body. The lower end surface of the fan cover body is provided with a first receiving groove for connecting to an inner top cover. The middle position of the inner bottom wall of the first receiving groove is provided with a second receiving groove for accommodating a fan. One side of the fan cover body is provided with an air inlet communicating with the second receiving groove. The second receiving groove is provided with a spiral air guide groove located outside the fan. The width of the air guide groove gradually decreases from one end to the other end.
[0006] With the above structure, the air inlet hood for an air fryer of this invention has the following advantages compared with the prior art: This invention features a spiral-shaped air guide groove within the second accommodating slot. Driven by a fan, air enters the second accommodating slot through the air inlet and flows along the air guide groove on the outer edge of the fan. As the width of the air guide groove gradually decreases, the wind speed flowing along it gradually increases, forming a high-speed airflow at the air inlet of the inner top cover, thereby further improving the air intake efficiency and ensuring that the cooking efficiency of the air fryer is not affected.
[0007] Preferably, the inner bottom wall of the second accommodating groove is provided with a semi-annular boss extending along its height direction, and the two free ends of the boss are connected to the two ends of the air inlet; the boss and the inner peripheral wall of the second accommodating groove form the air guide groove, and the boss and the inner bottom wall of the second accommodating groove form an air cavity, and the fan is housed in the air cavity. The boss and the fan cover body are integrally formed, reducing processing steps, and the air cavity accommodating the fan is formed at the same time as the air guide groove.
[0008] Preferably, one inner wall of the air inlet is inclined, and the width of the air inlet gradually decreases from the outside to the inside, which can speed up the air intake efficiency of the air inlet.
[0009] Preferably, the wider end of the air guide channel is located on the side near the inclined inner wall of the air inlet. This increases the air intake at the wider end of the air guide channel, thereby increasing the air velocity at the other end.
[0010] Preferably, the wind cover body has a first recess near the second receiving groove, and two mounting sleeves through which the power supply heating coil electrodes pass are provided in the first recess. The mounting sleeves penetrate the upper end face of the wind cover body. Two screw connecting posts are provided between the two mounting sleeves for connecting the electrode fixing components.
[0011] Preferably, the upper end face of the shroud body is provided with a first mounting base for connecting the temperature detection module, and the first mounting base is provided with a first through hole penetrating the shroud body for the detection probe of the temperature detection module to pass through.
[0012] Preferably, the upper end face of the fan cover body is provided with two second mounting seats, and the second mounting seats are provided with at least one second through hole for screws to pass through. The second mounting seats are used for connecting the drive motor of the fan.
[0013] Preferably, the second receiving groove has a shaft hole in the middle for the output shaft of the drive motor to pass through; the inner bottom wall of the second receiving groove has a countersunk hole at the position corresponding to the second mounting base for accommodating the screw head, hiding it, and preventing damage caused by the fan hitting the screw when it rotates.

[0020] like Figures 1-3 As shown, this utility model discloses an air inlet hood for an air fryer: it includes an air hood body 1, a first receiving groove 2 for connecting an inner top cover is provided on the lower end surface of the air hood body 1, a second receiving groove 3 for accommodating a fan is provided in the middle of the inner bottom wall of the first receiving groove 2, and an air inlet 4 communicating with the second receiving groove 3 is provided on one side of the air hood body 1; a spiral air guide groove 5 is provided in the second receiving groove 3 outside the fan, and the width of the air guide groove 5 gradually decreases from one end to the other end.
[0021] This invention features a spiral-shaped air guide trough 5 within the second accommodating groove 3. Driven by a fan, air enters the second accommodating groove 3 through the air inlet 4 and flows along the air guide trough 5 on the outer edge of the fan. As the width of the air guide trough 5 gradually decreases, the wind speed flowing along it gradually increases, forming a high-speed airflow at the air inlet of the inner top cover, thereby further improving the air intake efficiency and ensuring that the cooking efficiency of the air fryer is not affected.
[0022] The inner bottom wall of the second receiving groove 3 is provided with a semi-annular protrusion 6 extending along its height direction. The two free ends of the protrusion 6 are connected to the two ends of the air inlet 4. The protrusion 6 and the inner peripheral wall of the second receiving groove 3 enclose the aforementioned air guide groove 5. The protrusion 6 and the inner bottom wall of the second receiving groove 3 enclose the air cavity 7, and the fan is housed in the air cavity 7.
[0023] The boss 6 and the fan cover body 1 are integrally formed, which can reduce the processing steps and form the air cavity 7 to accommodate the fan while forming the air guide groove 5.
[0024] The inner wall of the air inlet 4 is inclined, and the width of the air inlet 4 gradually decreases from the outside to the inside, which can speed up the air intake efficiency of the air inlet 4.
[0025] The wider end of the air guide slot 5 is located on the side near the inclined inner wall of the air inlet 4. This increases the air intake at the wider end of the air guide slot 5, thereby making the air velocity at the other end faster.
[0026] A first recessed portion 8 is provided on the shroud body 1 near the second receiving groove 3. Two mounting sleeves 9 through which the power supply heating coil electrodes pass are provided in the first recessed portion 8. The mounting sleeves 9 penetrate the upper end face of the shroud body 1. Two screw connecting posts 10 are provided between the two mounting sleeves 9 for connecting the electrode fixing components.
[0027] For example Figure 2 As shown, the upper end face of the shroud body 1 is provided with a first mounting base 11 for connecting the temperature detection module. The first mounting base 11 is provided with a first through hole penetrating the shroud body 1 for the detection probe of the temperature detection module to pass through.
[0028] The upper end face of the fan cover body 1 is provided with two second mounting seats 12. Each second mounting seat 12 is provided with at least one second through hole for screws to pass through. The second mounting seat 12 is used for connecting the fan drive motor. The screw passes through the second through hole to fix the drive motor to the second mounting seat 12 of the fan cover body 1.
[0029] The second receiving groove 3 has a shaft hole 13 in the middle for the output shaft of the drive motor to pass through. The output shaft of the drive motor passes through the shaft hole 13 and extends into the air cavity 7, and is connected to the central shaft of the fan. The inner bottom wall of the second receiving groove 3 has a countersunk hole 14 at a position corresponding to the second mounting base 12. The second through hole penetrates the inner bottom wall of the countersunk hole 14. The screw can pass through the second through hole in the countersunk hole 14 and be fixedly connected to the drive motor. At this time, the countersunk hole 14 can hide the screw head and prevent the fan from being damaged by hitting the screw when it rotates.
