Description

Technical Field

[0001] This utility model relates to the field of kitchen appliances, and in particular to a dual-core air fryer with side suction. Background Technology

[0002] As people's living standards improve, the oil-free cooking method of air fryers is becoming increasingly popular. However, most existing air fryers are single-pot air fryers, meaning they only have one cooking chamber and one frying basket. These air fryers can only cook one type of food at a time, resulting in slow cooking speed, low efficiency, and a poor user experience. To meet user needs, a type of double-pot air fryer has emerged on the market. These air fryers typically have one cooking chamber and two frying baskets arranged side by side within the cooking chamber, allowing for the simultaneous cooking of two types of food. However, since there is only one frying / grilling component in the cooking chamber, the cooking speed is slow and the efficiency is low. Furthermore, the side-by-side arrangement of the two frying baskets increases the size of the air fryer, taking up a larger tabletop area, resulting in high space occupancy and a poor user experience. Utility Model Content

[0003] This application provides a dual-core air fryer with side-suction design to solve the technical problems of low cooking efficiency, high space occupation, and poor user experience of existing air fryers.

The body contains a first cooking chamber and a second cooking chamber arranged vertically at intervals. The first cooking chamber contains a first frying basket with an open top. A first hot air chamber is located on the rear side of the first cooking chamber, and a first hot air circulation system for generating circulating heat is located within the first hot air chamber. A first return air hole corresponding to the first hot air circulation system is located in the middle of the rear side wall of the first cooking chamber. A first air inlet communicating with the first hot air chamber is located on the upper part of the rear side wall of the first cooking chamber. A first ventilation hole communicating with the first return air hole is located on the side wall of the first frying basket. The second cooking chamber contains a second frying basket with an open top, and a second hot air chamber is located on the rear side of the second cooking chamber.

The basic principles of the present invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0035] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0036] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following drawings denote similar items; therefore, once an item is defined in one drawing, it need not be further discussed in subsequent drawings.

[0037] In the description of this utility model, it should be understood that the directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

By setting the first air inlet 112 to correspond to at least a portion of the first hot air circulation fan 22, the circulating airflow generated by the first hot air circulation fan 22 can enter the first cooking cavity 11 faster and better, thereby improving the heat flow circulation efficiency in the first cooking cavity 11, and thus improving the cooking efficiency of the air fryer.

[0055] like Figure 2 and Figure 3 As shown, in an optional embodiment, the second hot air circulation system 30 further includes a second hot air circulation fan 32, the projections of the second hot air circulation fan 32 and the second air inlet 112 on the rotation axis of the second hot air circulation fan 32 at least partially overlap. When the projections of the second hot air circulation fan 32 and the second air inlet 112 on the rotation axis of the second hot air circulation fan 32 at least partially overlap, the second air inlet 122 corresponds to at least a portion of the second hot air circulation fan 32. By setting the second air inlet 122 to correspond to at least a portion of the second hot air circulation fan 32, the circulating airflow generated by the second hot air circulation fan 32 can enter the second cooking cavity 12 faster and better, thereby improving the heat flow circulation efficiency in the second cooking cavity 12 and thus improving cooking efficiency.

[0056] like Figure 2 , Figure 5 and Figure 6 As shown, in an optional embodiment, the lower part of the side wall of the first frying basket 40 is provided with an inwardly recessed first recess 43, the first ventilation hole 41 is provided on the first recess 43, and a first hot air gap 115 communicating with the first return air hole 111 is adapted to be formed between the first recess 43 and the inner wall of the first cooking cavity 11.

By setting the first hot air gap 115 between the lower part of the first frying basket 40 and the inner wall of the first cooking cavity 11, the circulating hot flow flowing out of the first frying basket 40 can be quickly returned to the first hot air cavity 13 through the first hot air gap 115, thereby effectively improving the heat flow circulation efficiency in the first cooking cavity 11, and thus improving the cooking efficiency.

[0057] like Figure 2 , Figure 9 and Figure 10 As shown, the lower part of the side wall of the second frying basket 50 is provided with an inwardly recessed second recess 53, and the second ventilation hole 51 is provided on the second recess 53. A second hot air gap 125 is adapted to be formed between the second recess 53 and the inner wall of the second cooking cavity 12, communicating with the second return air hole 121. The second hot air gap 125 is adapted to provide sufficient flow space for the circulating hot flow. By setting the second hot air gap 125 between the lower part of the second frying basket 50 and the inner wall of the second cooking cavity 12, the circulating hot flow from the second frying basket 50 can be quickly returned to the second hot air cavity 14 through the second hot air gap 125, thereby effectively improving the hot flow circulation efficiency in the second cooking cavity 12, and thus improving the cooking efficiency.

[0058] like Figure 7 As shown, in an optional embodiment, the body 10 is provided with a heat dissipation duct 15 connected to the atmosphere, and a heat dissipation component 60 is provided inside the heat dissipation duct 15. A first air outlet channel 16 is provided outside the first cooking cavity 11. One end of the first air outlet channel 16 connects to the first hot air cavity 13 and the heat dissipation duct 15, and the other end connects to the atmosphere. The first air outlet channel is suitable for dissipating excess circulating heat flow in the first cooking cavity. By connecting the first air outlet channel to the heat dissipation duct, hot and cold air can be mixed and discharged from the first cooking cavity, effectively reducing the temperature of the airflow discharged from the air fryer, avoiding burns to the user, and thus improving user safety and experience.

[0059] like Figure 11 As shown, a second air outlet duct 17 is provided outside the second cooking cavity 12. One end of the second air outlet duct 17 connects to the second hot air cavity 14 and the heat dissipation duct 15, and the other end connects to the atmosphere. The second air outlet duct 17 is used to discharge excess circulating heat flow in the second cooking cavity 12. By connecting the second air outlet duct 17 to the heat dissipation duct 15, the hot and cold air from the second cooking cavity 12 can be mixed, effectively reducing the temperature of the airflow discharged from the air fryer, avoiding burns to the user, and thus improving user safety and experience.
