CROSS-REFERENCE TO RELATED APPLICATIONS

This application claims priority to Chinese Patent Application No. 202322306527.4, filed on Aug. 25, 2023, the content of which is incorporated herein by reference in its entirety.

TECHNICAL FIELD

The application relates to the technical field of air fryers, and in particular, to a dual-chamber air fryer with easily removable pot sets.

BACKGROUND

Air fryers mainly cook food by using air to replace hot oil originally in a frying pan, and at the same time, hot air blows away moisture on the surface layer of the food to achieve a similar effect of frying food ingredients. The basic working principle of the air fryer is the “high-speed air circulation technology”, where air is heated at high temperature by heating tubes in the air fryer to produce hot air, then, high-temperature air is blown into a pot by a fan to heat the food in the pot, and the hot air is circulated in a sealed space to fry the food by virtue of oil therein to thus dehydrate the food and make the surface of the food golden and crispy, thereby achieving a frying effect.

In a specific use process, in order to facilitate a user to frequently observe part of the food to be processed in the air fryer, a visible window structure is added to facilitate operations such as observation, stirring, turning, picking and placing. In this way, the problem concerning food observation is solved to certain extent. However, since a conventional visible window structure is integral and unremovable, oil stains are accumulated in a gap between the fryer and a panel after long-term use. That is, oily fume or other debris enter a cavity in the middle of the visible window structure. This prevents the user from observing the condition of food, but also makes it difficult for the user to carry out removal and cleaning.

In order to cook a variety of different food at the same time and improve the cooking efficiency when the air fryer is used, a dual-chamber air fryer is gradually applied to scenes of life. The air fryer of this type generally includes an outer housing and an inner housing; the inner housing is provided with two cooking chambers configured for placement of corresponding cooking pot sets, respectively; a hot air fan and a heating tube are mounted on the inner housing and above the cooking chambers; the heating tube is configured to heat air; and under the action of the hot air fan, the high-temperature air flows through the cooking pot sets to cook food ingredients correspondingly. However, there is generally no air flowing in an entrapping passage between the two cooking chambers in the existing dual-chamber air fryer, easily leading to high-temperature dead angle during working. After working for a long time, the air fryer undergoes certain thermal deformation or melting or other abnormal conditions.

A drive element 26 is mounted on the upper integral core 17, and the output end of the drive element 26 is sequentially and coaxially provided with an air intake structure 19 and a hot air fan 27. The mounting and operating principles of the air intake structure 19 and the drive element 26 are both based on the prior art, which will not be repeated here in detail.

The cold air circulating structure includes cover portions 28, which are formed by protruding from the upper integral core 17; the air inlets 25 are disposed in the cover portions 28; the air intake structure 19 is installed in and adapted to each cover portion 28; heating tubes are mounted on the upper integral core 17 and located below the hot air fan 27; and when the air intake structures 19 and the heating tubes work, the air intake structures 19 blow high-temperature air flows to the two cooking chambers 11, respectively.

After the power is turned on, the drive element 26 drives the air intake structures 19 and the hot air fan 27 to operate at the same time; by means of the hot air fan 27, the air in the inner pot 500 forms forced convection and passes through the heating tubes, which heat the flowing air; and under the continuous action of the hot air fan 27, the high-temperature air constantly flows in the inner pot 500 to cook the food ingredients.

The air intake structures 19 rotate to drive the air in the upper part in the inner housing 13 to mix with cold air drawn in by the air intakes 16 in the top of the outer housing 12 and then enter the corresponding cover portions 28; part of the air is delivered outward along the main outlet air flow passage 21 under the action of the air intake structure 19; the main outlet air flow passage 21 is disposed at the back side of the fryer body 10, thereby preventing the air flowing out from burning a user; and the other part of the air flows to the entrapping passage 15 along the air guiding port 23, the air guiding passage 24, and the cold air outlet 22 sequentially, allowing the air in the entrapping passage 15 to flow. Due to the structural factors of the cooking chambers 11a and 11b and the shunt plate 50 below the entrapping passage 15, the air is divided into two parts here. One part of the flowing air continuously moves downward, reaches the bottom of the outer housing 12 and then disperses to both sides to flow through the outer surface of the entire inner housing 13 along the cold air passage 14 on both sides, respectively; when flowing through the bottom of the lower integral core 18, the air is mixed with cold air drawn in by the air intakes at the bottom of the outer housing 12, subsequently flows together to the top of the upper integral core 17, and is again drawn by the air intake structure 19 for a new circulation.

The other part of the flowing air flows to the rear of the entrapping passage 15, is mixed with the cold air drawn in by the air intakes 16 at the bottom of the outer housing 12, and then flows to the top of the upper integral core 17, also forming a circulation of flowing cold air. In this way, two internal circulations jointly complete the cooling of the bottom of the air fryer, and both the two internal circulations pass through the entrapping passage 15, such that the entrapping passage 15, as a cooling dead angle, can be cooled better.

Embodiment VI

As shown in FIG. 34, this embodiment differs from Embodiment V in that the heating tubes in the internal structure are optimized to implement multiple power modes, thereby expanding the range of use to meet the heat requirements for cooking different food.

Two mounting cavities 13a are disposed in the top of the inner housing 13. That is, an upper integral core 17 is provided with two mounting cavities 13a. A first heating tube set 29 and a second heating tube set 30 are mounted in the two mounting cavities 13a, respectively; and the two mounting cavities 13a vertically correspond to the corresponding cooking chambers 11, respectively.

The first heating tube set 29 and the second heating tube set 30 are both electrically connected to a control panel, on which a plurality of matching buttons are provided to thus change or adjust the operating mode according to needs.

Specifically, the first heating tube set 29 includes a heating tube A and a heating tube B, and the second heating tube set 30 includes a heating tube C. The power of the heating tube A is greater than the power of the heating tube B; the power of the heating tube C is greater than the power of the heating tube B; and the sum of the power of the heating tube A and the power of the heating tube B is equal to the sum of the power of the heating tube B and the power of the heating tube C. The first heating tube set 29 corresponds to the cooking chamber 11a, and the second heating tube set 30 corresponds to the cooking chamber 11b. Preferably, the power of the heating tube A is 1150 W, the power of the heating tube B is 400 W, and the power of the heating tube C is 1150 W.

In this embodiment, the operating modes of the first and second heating tubes are as follows.

When the cooking chamber 11a operates alone, the heating tubes A and B operate at the same time for heating, i.e., high heat here.

When the cooking chamber 11a operates alone, the heating tube A operates for heating, i.e., intermediate heat here.

When the cooking chamber 11a operates alone, the heating tube B operates for heating, i.e., low heat here.

When the cooking chamber 11b operates alone, the heating tube C operates for heating.

In a case where both the cooking chamber 11a and the cooking chamber 11b operate for alternate heating, when working for the cooking chamber 11a, the heating tube A and the heating tube B operate at the same time for heating; and when working for the cooking chamber 11b, the heating tube B and the heating tube C operate for heating. That is, when the cooking chamber 11b operates, the heating tube B operates for heating to make up for the power difference between the power of the heating tube C operating alone and the total power, and moreover, more energy can be supplied to the large chamber to achieve a better cooking effect.

In a case where both the cooking chamber 11a and the cooking chamber 11b operate for alternate heating, when working for the cooking chamber 11a, the heating tube A or the heating tube B operates for heating; and when working for the cooking chamber 11b, the heating tube C operates for heating. That is, in an ordinary mode with a single heating tube for heating, it is necessary to choose between high power and low power for the cooking chamber 11a.

In a case where both the cooking chamber 11a and the cooking chamber 11b operate for alternate heating, when working for the cooking chamber 11a, the heating tube A and the heating tube B operate at the same time for heating; and when working for the cooking chamber 11b, the heating tube C operates for heating.

When the cooking chamber 11a and the cooking chamber 11b operate at the same time or synchronous heating, the heating tube A and the heating tube C operate at the same time for heating, or the heating tube B and the heating tube C operate at the same time for heating.

The above combinations are intended to meet the heat requirements of different food, such that more types of food ingredients can be cooked by the air fryer, or one food ingredient can be cooked with different combinations depending on the cooking stage to achieve a better cooking effect.
