Description

TECHNICAL FIELD

[0002] The air fryer on the market is mostly single-cavity, which can cook a large amount of food at a time and is suitable for simultaneous consumption by multiple people. In order to meet the needs of cooking small amounts of food at a time or cooking different types of food at the same time, the single cavity is divided into two cavities. The existing heating device is usually installed at the top of the heating cavity. In actual use, hot air is concentrated in the top area, which can easily cause the food close to the heat source to be overheated, while the food at the bottom may not be heated enough. In addition, the double-cavity design leaves little space at the top of each cavity, making it difficult to install the heating device.

[0003] The double-cavity air fryer generates more heat than the single-cavity air fryer. Relying on a single fan or a simple air duct structure is not enough to discharge heat in time, resulting in low heat flow efficiency in the cavity, which further exacerbates the uneven heating of food. The low heat dissipation efficiency can also cause the equipment to overheat during long-term use of the air fryer, increasing the aging rate of the motor and other components and posing a certain safety risk.

A plurality of hanging buckles 611 are formed on the bottom of the top plate 61. A buckle groove 621 is arranged on the top of the surrounding plate 62.

[0027] The adjacent buckle groove 621 is hollowed out to form an upper air inlet groove 63, and the bottom side wall of the buckle groove 621 is open to provide an upper air inlet 64. The upper air inlet groove 63 is in communication with the upper air inlet 64, and the upper air inlet groove 63 is in communication with the upper air inlet 64.

[0028] The bottom plate assembly 7 is mounted on the bottom of the shell 1, and the bottom plate assembly 7 includes a bottom cover 71 and a base 72. The bottom cover 71 extends downward and protrudes a plurality of positioning columns 711. Correspondingly, the base 72 is provided with a mounting column 721. The mounting column 721 and the positioning column 711 are sequentially screwed by a fixing screw, so that the bottom cover 71 and the base 72 are connected as a whole.

[0029] The bottom of the base 72 is provided with a plurality of lower air inlets 73, and the end surface of the bottom cover 71 is provided with a plurality of lower air inlet grooves 74. The lower air inlets 73 and the lower air inlet grooves 74 are in communication with the lower air duct and the heat dissipation mechanism 5.

[0030] The heating mechanism includes a hot air blower 3 mounted on the inner wall of the back of the baking cavity, and a heating device wrapped around the outer periphery of the hot air blower 3. The main shaft 42 of the driving mechanism 4 is connected with the hot air blower 3.

[0031] The driving mechanism 4 includes a driving motor 41 and a main shaft 42. The main shaft 42 is inserted into the cold air blower 52 and the hot air blower 3, and synchronously drives the cold air blower 52 and the hot air blower 3 to rotate.

[0033] The outer side wall of the air guide shell 53 is provided with a plurality of air outlets 54, and the air outlets 54 are arranged towards the outer end.

[0034] Working principle: Unlike the traditional heating device arranged at the top of the baking cavity, the heating device in the case is installed at the back of the baking cavity, and the upper baking cavity and the lower baking cavity are heated separately and independently. Users can simultaneously cook different types of food in the two cavities, meet the needs of users for diversified cooking, and improve the cooking efficiency.

[0035] In order to further improve the baking efficiency, the heating device is matched with the hot air blower of the heating mechanism. The hot air blower is wrapped in the electric heating wire tube, and the hot air blower is used to blow hot air, so as to realize the uniform circulation of hot air in the baking cavity and ensure uniform heating.

[0036] In order to dissipate heat inside the baking cavity, a heat dissipation area is formed between the shell and the inner container, and a heat dissipation mechanism is used to quickly discharge heat from the heat dissipation area.

[0037] Wherein, the upper air duct is arranged on the top of the upper baking cavity, and the external air is guided to the heat dissipation mechanism through the upper air duct. It should be noted that the several hanging buckles formed by the top plate of the cover plate assembly are connected with the buckle grooves arranged on the top of the surrounding plate, and the upper air inlet grooves are arranged at the adjacent positions of the buckle grooves, and the upper air inlets are arranged on the bottom side walls of the buckle grooves. The external air enters the cover plate assembly through the upper air inlet grooves, and then flows through the upper air inlets into the upper air duct under the blowing of the air cooler, so that the heat dissipation operation of the heat dissipation area is performed, and finally the air is discharged through the air guide shell.

[0038] The lower air duct is arranged on the bottom of the lower baking cavity, and the external air is guided to the heat dissipation mechanism through the lower air duct. It should be noted that the several lower air inlets are arranged on the bottom of the base of the bottom plate assembly, and the several lower air inlet grooves are arranged on the end surface of the bottom cover. The external air enters the bottom plate assembly through the lower air inlets, and then flows through the lower air inlet grooves into the lower air duct under the blowing of the air cooler, so that the heat dissipation operation of the heat dissipation area is performed, and finally the air is discharged through the air guide shell.

[0039] The upper air duct and the lower air duct are arranged respectively, and the upper baking cavity and the lower baking cavity are cooled and cooled separately. The multi-air duct circulation design optimizes the path of air flow, so that the external air can quickly enter the heat dissipation area to cool the air fryer, and the heat dissipation performance is enhanced to ensure the stability of the air fryer in high-intensity operation.

[0040] The main shaft of the driving mechanism is connected in the air cooler and the hot air machine, so that the driving heat dissipation mechanism and the heating mechanism work synchronously. When the air fryer starts to work, the hot air machine drives the hot air to circulate in the baking cavity to complete the cooking of the food, and the air cooler simultaneously discharges the heat generated during the operation through the heat dissipation area. The hot air and cold air double circulation system work synchronously, so that the air fryer ensures the cooking efficiency and realizes good heat dissipation performance. The internal structure of the air fryer is simplified, and the multiple kinetic energy is synchronized and coordinated in the compact and narrow space, so that the safety and stability of the equipment are ensured, and the service life of the equipment is prolonged.
