This air fryer relies on hot-blast fan and heating device to heat the barbecue to placing the edible material in the container to the completion is to the processing of edible material. However, the product has a single function, and the food cannot be turned and baked during the processing process, which causes uneven processing of the food.

As a product of improving the promotion, still include an air fryer that sets up agitating unit, can further stir the upset to the edible material in the container, especially for less, dispersed edible material, difficult processing when edible material piles up is even, sets up agitating unit and can solve this problem.

However, the relative processing function of the air fryer is still single, the air fryer can only be used for barbecuing food materials, and can be used for continuously barbecuing the food materials, so that the food materials are too dry, and particularly when meat is processed, the meat food materials are dehydrated too much, and the taste of the meat food materials is affected.

To solve the above problems, the application No. CN201720587695.7 discloses an air fryer, which comprises a water storage device disposed in a container, and water is filled in the water storage device, during the operation, the water in the water storage device is heated to form steam, and the steam enters into a containing cavity, so that the temperature in the containing cavity is increased, and the taste of the food is improved.

However, this kind of air is fried pot and is directly set up water storage device in holding the intracavity, and in the course of the work, if there is water in the water storage device, then can realize increasing the function of steam, or no water or water is evaporated in the water storage device, then can't realize heating and hold the purpose in chamber again to, water storage device sets up in holding the intracavity, if the procedure of setting for does not need steam to heat, but if the user is water injection in water storage device, then production of uncontrollable steam in the course of the processing can't make edible material by better processing on the contrary. The water storage device only depends on the heating device of the air fryer to realize heating, the steam generation speed is increased along with the temperature rise in the accommodating cavity, but the steam speed cannot be controlled, and the function of quickly generating steam cannot be met; and the water storage device can absorb part of the heat generated by the heating device, so that the whole processing efficiency of the air fryer is reduced.

The air fryer needs to be provided with a driving structure to drive the stirring device, and meanwhile, a water storage device needs to be additionally arranged to achieve the purpose of generating steam, the structure is complex, the driving device and the water storage device cannot be effectively combined, only the functions are overlapped, the volumes of the driving device and the water storage device are occupied, and the space utilization rate of the air fryer is reduced.

The water storage device is arranged in the accommodating cavity, particularly the water storage device is arranged on the stirring device, so that the stress of the stirring device is increased, and particularly when the water storage device is arranged at the upper end of the stirring device, the stirring device is easily shaken, abraded and the like due to the influence of gravity; the water storage device is added in the accommodating cavity, so that the space of the existing accommodating cavity is inevitably occupied, and the accommodating effective utilization rate of the air fryer is reduced. The water storage device is arranged in the accommodating cavity, and steam generated in the processing process can enter the machine body, particularly along the driving structure

In summary, the prior art has a complex structure and a single function, and only partially solves the defects of the prior art, for example, when a user needs a large amount of steam to realize a pure steam function, the requirement cannot be met.

It will be appreciated that a gap is provided between the stirring means and the drive shaft, and steam can be injected into the vessel through the gap between the stirring means and the drive shaft without providing a separate vent.

It is to be understood that the air outlet hole may be located axially below the agitating blade.

It is understood that the air outlet can be arranged at the top end of the stirring paddle.

It can be understood that the driving shaft can be separately arranged, the driving shaft comprises a driving section and a transmission section, the driving section is communicated with the steam generator, the transmission section is arranged on the container and is detachably communicated with the driving section, and the driving section and the transmission section are arranged in a hollow mode.

Example two.

As a second embodiment of the air fryer with reliable transmission of the utility model, the main difference with the first embodiment is that an air inlet grille is further arranged in the air inlet cavity.

As shown in fig. 7, the air inlet chamber includes an air inlet 20 and an air outlet 221, the air inlet is located at a side portion of the air inlet chamber 2, the air outlet 221 is located at a center of the air inlet chamber 2, an air inlet grille 26 is further disposed on an inner wall of the air inlet chamber, the air inlet grille 26 is disposed on an inner side wall of the air inlet chamber 2, the air inlet grille 26 is spirally raised, and steam entering the air inlet chamber 2 can spirally raise along the air inlet grille 26 and is discharged through the air outlet 221.

Through the arrangement of the air inlet grille, the movement path of the steam in the air inlet cavity is more controllable. On one hand, when steam enters the air inlet cavity, due to the change of the volume and the effective section, the pressure of the steam is released and is gathered in the air inlet cavity again to form steam with stable pressure, and then the steam is transmitted to the accommodating cavity through the driving shaft, so that the processing reliability of the air fryer is ensured; on the other hand, the motion path of the steam in the air inlet cavity is prolonged by the air inlet grille, the time for the corresponding steam to be remained in the air inlet cavity is longer, the steam with unstable pressure generated by the steam generator is released fully in the air inlet cavity, the steam pressure discharged by the air inlet cavity is stable and controllable, and the stability and the reliability of the air fryer in the processing process are further realized.

It is understood that the intake grill is provided in plural and spaced apart from each other.

It can be understood that the air inlet is located at the bottom of the side wall of the air inlet cavity, the air outlet is located at the top end of the side wall of the air inlet cavity, the air inlet and the air outlet are arranged oppositely, the steam generator further comprises a steam pipe located at the air outlet, and the steam generator is communicated with the driving shaft through the steam pipe.

It will be appreciated that the inlet is located at the top of the side wall of the inlet chamber and the outlet is located at the bottom of the inlet chamber or at the bottom of the side wall, with steam entering the inlet chamber from the upper part and exiting the inlet chamber from the lower part. Because the steam has upward buoyancy, the air inlet cavity is reversely arranged, so that the steam in the air inlet cavity can be better exhausted from the air outlet only by subsequent steam compression, and the pressure of the steam is subjected to a plurality of steps of releasing, re-gathering, pressurizing and the like through the change of the volume in the air inlet cavity, and finally the exhausted steam pressure is controllable and stable, thereby ensuring the stability and reliability of food material processing. The in-process that the steam oppressed downwards, the drop of water that remains in the steam can condense to finally gather in the air inlet cavity, discharge such as rethread drainage structures has guaranteed that the steam that gets into and holds the chamber is pure high-efficient.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention, i.e. all equivalent changes and modifications made according to the present invention are covered by the scope of the claims of the present invention, which is not illustrated herein.
