This application claims priority to Chinese Patent Application CN201920085873.5 filed on 18 Jan. 2019.
This invention relates to a heating device, in particular to a heating device for an air fryer and an air fryer comprising the heating device.
The conventional air fryer usually has a pot body of fixed volume. To fry foods of different sizes, people often use fryers of different sizes, which not only occupy storage space but also are expensive.
A heating device comprises a housing, a driving member a fan, a heating member and a cover. The housing is formed with a cavity, with a heating member within the cavity. The cover has annular steps with the diameter of the outer surface of the annular steps being gradually reduced in an axial direction. The annular steps can accommodate different pots having
A wide variety of practical and useful embodiments will be more readily understood through the following detailed description of certain exemplary embodiments, concerning the accompanying exemplary drawings in which:

The above and other objects, features and other advantages of the present invention will be more clearly understood from the following detailed description taken in conjunction with the accompanying drawings. It should be noted that like reference numerals refer to like parts throughout the several views.
“Exemplary” means “serving as an example, instance or description” and any illustration or embodiment described herein as “exemplary” should not be construed as a more preferred or advantageous technical solution.
The “first” and “second” described herein are not intended to distinguish their importance.
Referring to
The cover 50 has an annular stepped shape and is sleeved on the housing 10. The axis of the cover extends along the first direction. The diameter of the outer surface of the cover 50 is gradually reduced along the first direction Z from top to bottom in
The cover 50 is transparent and made of a heat resistant material to that the user can see the cooked food in the pot during cooking. However, it is not limited thereto, and in other exemplary embodiments, a non-transparent design may also be adopted according to actual needs.
The heating device when used as an air fryer has a cover 50 having the annular stepped shape. The cover 50 is sleeved on the housing 10, and the hot air is discharged from the cover 50. One cover 50 can be used different pots having different diameters, the openings of the pots being accommodated via the annular steps with gradually decreasing diameters. The diameter of the annular step can match the opening of the pot with the same diameter. When an annular step matches the opening of the pot, the closest annular step with a larger diameter covers the pot; therefore using only one heating device that can accommodate several pots can meet a variety of user requirements, which can save storage space and cost.
At this time, each second engaging part 52 is abutted against the side, which is closer to the restriction portion 16, of each first engaging part 142. The first engaging parts 142 and the restriction portion 16 are against each other and fix the cover 50 in two directions. The cover 50 and the housing 10 are detachably mounted by the above structure. It is easy to disassemble when cleaning the cover 50. However, it is not limited thereto. In other exemplary embodiments, the cover 50 and the housing 10 may also adopt other detachable connection assemblies.
In an exemplary embodiment, referring to
In an exemplary embodiment, referring to
In an exemplary embodiment, two concave members 17 are formed at the second portion 19. The concave members are in the opposite direction from each other on the second portion 19 so that two concave members form a handle for the user to pick up. In
The second portion 19 further includes a plurality of apertures 15 communicating with the cavity 12 so that the air can be discharged through these apertures 15.
The heating device has a frying function, is simple in structure, and is easy for the user to grasp.
In an exemplary embodiment, there is also provided an air fryer comprising the above heating device and a plurality of pots. The pots have openings of different diameters. The annular steps of the cover 50 can match the openings of the different pots. For example, the diameters of the steps of the cover 50 are the same as the diameters of the different openings of the pots. Therefore; the annular steps with different diameters are suitable for pots of different sizes, as shown in
Still other substantially and specifically practical and useful embodiments will become readily apparent to those skilled in this art from reading the above-recited and/or herein-included detailed description and/or drawings of certain exemplary embodiments. It should be understood that numerous variations, modifications, and additional embodiments are possible, and accordingly, all such variations, modifications, and embodiments are to be regarded as being within the scope of this application.
