TECHNICAL FIELD

[0001] The present application relates to the technical field of kitchen appliances, in particular to an air fryer. BACKGROUND

[0002] The air fryer is a kitchen cooking appliance that can use air to "fry", its main principle is to use high-speed air circulation technology to replace the hot oil in the traditional frying pan with rapidly circulating hot air to make the food in the air fryer cooked; at the same time, the generated hot air can also blow away the moisture on the surface of the food, so that the surface of the food forms a crisp layer, locking the moisture inside the food to achieve the cooking effect similar to frying.

DETAILED DESCRIPTION

[0030] In order to better understand and implement, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the accompanying drawings in the embodiments of the present application.

[0031] In the description of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the present application belongs. The terms used in the specification of the present application herein are only for the purpose of describing the specific embodiments and are not intended to limit the present application.

[0033] Referring to Figures 1-6 As shown, the present application first provides an air fryer, which comprises a body 100, and the inside of the body 100 is provided with at least a first cooking cavity 2 and a second cooking cavity 3. In this embodiment, the air fryer is a double-pot air fryer, and the cooking cavities are provided with two, which are the first cooking cavity 2 and the second cooking cavity 3.

[0034] The upper part of the first cooking cavity 2 is provided with a first heating cavity 4 communicated with the first cooking cavity 2, and a first heating element 15 is arranged in the first heating cavity 4, which is a heating tube in this embodiment. The upper part of the second cooking cavity 3 is provided with a heat dissipation cavity 16 for dissipating heat inside the machine body 100. A wind guide channel 6 is arranged between the heat dissipation cavity 16 and the first heating cavity 4, so as to guide the air blown out by the heat dissipation cavity 16 to enter the first cooking cavity 2 through the wind guide channel 6 and the first heating cavity 4. Thus, the air flowing through the first heating cavity 4 after being heated by the heat dissipation cavity 16 enters the first cooking cavity 2, so as to heat and cook the food in the first cooking cavity 2. Therefore, it is not necessary to arrange a fan blade for hot air circulation, a heat dissipation fan blade 11 and a motor for driving the two fan blades to rotate in the machine body 100 for the first cooking cavity 2, thereby reducing the arrangement of parts. In addition, the temperature of the air in the heat dissipation cavity 16 is higher than that of the normal temperature air, so that the air flowing through the heat dissipation cavity 16 is heated, which not only improves the heating speed of the hot air, but also realizes the reuse of the heat energy which needs to be directly discharged originally.

[0035] Therefore, the wind guide channel 6 is arranged in the machine body 100 to communicate the heat dissipation cavity 16 with the first cooking cavity 2, so that the air flowing through the first heating cavity 4 after being heated by the heat dissipation cavity 16 enters the first cooking cavity 2, so as to heat and cook the food in the first cooking cavity 2. Therefore, it is not necessary to arrange a fan blade for hot air circulation, a heat dissipation fan blade 11 and a motor for driving the two fan blades to rotate in the machine body 100 for the first cooking cavity 2, thereby reducing the arrangement of parts. In addition, the temperature of the air in the heat dissipation cavity 16 is higher than that of the normal temperature air, so that the air flowing through the heat dissipation cavity 16 is heated, which not only improves the heating speed of the hot air, but also realizes the reuse of the heat energy which needs to be directly discharged originally.

[0036] The shape of the wind guide channel 6 can be various, which can be directly arranged as a single pipe shape or a single groove shape. Of course, in a preferred embodiment, the wind guide channel 6 at least includes a wind guide section 61 and a diameter expansion section 62. The wind guide section 61 is communicated with the heat dissipation cavity 16, and the diameter expansion section 62 is connected between the wind guide section 61 and the first heating cavity 4, and the width of the diameter expansion section 62 is greater than that of the wind guide section 61. Thus, the air can be guided through the wind guide section 61 and then expanded through the diameter expansion section 62 to achieve a larger blowing range and better heating effect on the food in the first cooking cavity 2. In different embodiments, the wind guide section 61 can be arranged as two wind guide sections 61 and one diameter expansion section 62, or three wind guide sections 61 and one diameter expansion section 62, which will not be described here.

[0037] Further, as shown in Figure 2 and Figure 6 In a preferred embodiment, the air guide section 61 is connected to one end of the diameter expansion section 62 in a trumpet shape. In this way, the first diameter expansion is achieved through the trumpet-shaped port, and the second diameter expansion is achieved by reaching the diameter expansion section 62, thereby achieving a better air flow expansion effect.

[0038] When the air guide channel 6 includes an air guide section 61 and a diameter expansion section 62, the air guide section 61 and the diameter expansion section 62 are arranged vertically, so that the air guide channel 6 as a whole is in a T shape.

[0039] The first cooking cavity 2 is provided with a first heat insulation cover 7 above, a first heating cavity 4 is formed in the first heat insulation cover 7, and a first opening 71 is provided on the first heat insulation cover 7 and communicates with the first heating cavity 4 and the air guide channel 6; the second cooking cavity 3 is provided with a second heat insulation cover 8 above, a second heating cavity 5 is formed in the second heat insulation cover 8, and the first heat insulation cover 7 and the second heat insulation cover 8 are integrally formed. In this way, by integrally forming, the installation mode of the two separate heat insulation cover structures in the past is changed, and the assembly efficiency is improved. In addition, in this embodiment, the bottom of the first heat insulation cover 7 is directly communicated with the first cooking cavity 2, and the top of the first heat insulation cover 7 is provided with the first opening 71. In this way, the air flow of the air guide channel 6 flows from the top of the first heat insulation cover 7 towards the first cooking cavity 2, so as to realize the same air flow direction in the cooking cavity of the traditional air fryer, realize the same food making mode, and therefore the food making will not cause the taste to be worse due to the air guide structure.

[0040] The upper portion of the second heat insulation cover 8 is provided with a heat dissipation cover 9, a heat dissipation cavity 16 is formed in the heat dissipation cover 9, and a second opening is provided on the heat dissipation cover 9 and communicates with the heat dissipation cavity 16; the upper portion of the first heat insulation cover 7 is provided with an air guide cover 10 connected with the heat dissipation cover 9, an air guide channel 6 is formed in the air guide cover 10 and communicates with the second opening. In this way, the air flow is blown out from the second opening in the heat dissipation cavity 16 to enter the air guide channel 6, and then guided by the air guide channel 6 to enter the first heating cavity 4 through the first opening 71, and finally enter the first cooking cavity 2 to circulate and flow out from the fourth outlet 72 provided on the first heat insulation cover 7 to the outside of the machine body 100, realizing the flow of the air flow.

[0041] The air guide cover 10 and the heat dissipation cover 9 are integrally formed, and similarly, by integrally forming, the installation mode of the two separate cover structures in the past is changed, and the assembly efficiency is improved.

[0042] The heat dissipation cavity 16 is provided with a heat dissipation fan blade 11; the second heating cavity 5 is provided with a heat circulation fan blade 12 and a second heating element 13 from top to bottom, and the second heating element 13 is a heating tube in this embodiment; the heat dissipation cover 9 is provided with a driving motor 14, the driving shaft of the driving motor 14 penetrates the heat dissipation cover 9 and the second heat insulation cover 8 and is connected with the heat dissipation fan blade 11 and the heat circulation fan blade 12. That is, the heat dissipation fan blade 11 and the heat circulation fan blade 12 are driven to rotate by one driving motor 14, and then only one driving motor 14 needs to be set to work, so that the first cooking cavity 2 and the second cooking cavity 3 can be used to make food at the same time, thereby changing the traditional way of making food in two cooking cavities at the same time by driving two heat circulation fan blades 12 to rotate by one motor, and the improvement effect is obvious. Of course, in actual use, the first cooking cavity 2 and the second cooking cavity 3 do not necessarily need to make food at the same time, so that the heating of the air flow can be stopped by closing the first heating element 15 or the second heating element 13.

[0043] In addition, it should be noted that the heat dissipation cavity 16 is used for heat dissipation inside the machine body 100, and in this embodiment, the heat dissipation cavity 16 is used not only to provide heat dissipation for the second heat insulation cover 8, but also to provide heat dissipation for the driving motor 14.

[0044] The top of the heat dissipation cover 9 is provided with a third opening 101, and the side of the heat dissipation cover 9 is provided with a second opening; the heat dissipation fan blade 11 is a centrifugal impeller with axial air inlet and radial air outlet. In this embodiment, the side of the heat dissipation cover 9 is provided with two second openings, one of which is communicated with the air guide channel 6, and the other is communicated with the outside. In this way, when the centrifugal impeller rotates, air enters the heat dissipation cavity 16 from the third opening 101 and is discharged from the two second openings, part of the air flow enters the heat dissipation cavity 16, and the other part of the air flow is discharged to the outside of the machine body 100.

[0045] The volume of the first cooking cavity 2 and the second cooking cavity 3 can be the same or different, and in a more preferred embodiment, the volume of the first cooking cavity 2 is smaller than that of the second cooking cavity 3. In this way, when the user only needs to make one piece of food, the appropriate size of the cooking cavity can be selected according to the needs, which is convenient for the user to use.

[0046] The technical means disclosed in the present application scheme is not limited to the technical means disclosed in the above embodiments, but also includes the technical solutions composed of any combination of the above technical features.
