3, 5b, 5c, 6 and 7, the upper cover assembly 10 includes an upper casing 20, a water pump 91, a mounting cover 30 and two heat collecting covers 40. The water pump 91 is used to provide a double-gallbladder air fryer. 100 cooking chambers are supplied with water. A portion of the side wall 25 of the upper casing 20 is configured with a step portion 24. The step portion 24 includes a first shell wall area 21 that is inclined toward the water pump 91 relative to the height direction H of the double-gallbladder air fryer; the upper casing 20 and the installation cover 30 together enclose the installation cavity S. The installation cover 30 is provided with a first air inlet 31 for connecting the installation cavity S with the outside world. The two heat collecting covers 40 and different areas of the installation cover 30 enclose two independent cooling chambers. L, each cooling cavity L has a first air outlet 32 corresponding to the upper casing 20 for connecting the cooling cavity L with the outside world. Exemplarily, the first air inlet 31 is located on the bottom side of the display panel assembly 60 .

The heating component 50 is disposed on the side of each heat collecting cover 40 away from the installation cover 30 and above the inner tank component 80 , and part of the structure of the heating component 50 extends into the installation cavity S. The display panel assembly 60 includes a display panel 61 , which is disposed close to the inner wall side of the first housing wall area 21 and located in the installation cavity S.

The fan assembly 70 includes two cooling fans 72 respectively disposed in the two cooling cavities L. The installation cover 30 has a vent 35 corresponding to the position of the two cooling fans 72 to connect the installation cavity S and the two cooling cavities. L, the cooling fan 72 rotates to form a cooling cycle between the outside world, the first air inlet 31 and the installation cavity S, the cooling cavity L, and the first air outlet 32 .

By configuring part of the side wall 25 of the upper casing 20 with a step portion 24, the step portion 24 includes a first shell wall area 21 that is inclined inward relative to the height direction H of the double-gallbladder air fryer, so that the display panel 61 is placed against It is arranged on the inner wall side of the first shell wall area 21, which is equivalent to arranging the display panel 61 at an angle. Compared with the related technology in which the step portion 24 is not provided on the side wall 25, the occupied space of the upper cover assembly 10 can be reduced, making the double-gallery The top of the air fryer 100 is smaller in volume, the display panel assembly 60 is lower than the upper cover assembly 10 , and the top of the first shell wall area 21 relative to the height direction H of the double-gallbladder air fryer is lower than the top wall 27 by at least 45mm, so that the operation is more convenient when using double-gallbladder air frying, and the display panel assembly 60 is arranged at an end away from the heating assembly 50 .

On the other hand, the installation cavity S is provided with a first air inlet 31, the two cooling cavities L are both connected to the installation cavity S, and each cooling cavity L is provided with a first air outlet 32. The cooling cavity L is provided with a first air inlet 31. Driven by the fan 72, the external cooling air enters the installation cavity S through the first air inlet 31, and since the first air inlet 31 is located at the bottom side of the display panel assembly 60, the cooling air will pass through the bottom side of the display panel assembly 60. The display panel 61 is cooled to a certain extent, passes through the water pump 91, enters the cooling chamber L, and is discharged to the outside through the first air outlet 32, forming a cooling cycle. Even if part of the structure of the heating assembly 50 extends into the installation cavity S, causing the temperature in the installation cavity S to be relatively high, due to the existence of the cooling cycle, the heat generated by the joint part 52 can be taken away, and the display panel 61 can be processed. Better cooling improves the working reliability of the double-gallbladder air fryer 100.

The display panel 61 is disposed close to the inner wall side of the first housing wall area 21 , which means that the direction of the display panel 61 is substantially parallel to the extending direction of the first housing wall area 21 , making it easier for the user to pass through the first housing wall area 21 Observe the displayed information on the display panel 61. Of course, the first housing wall area 21 is configured to transmit information displayed on the display panel 61 . In fact, since the first housing wall area 21 is tilted, the final installation posture of the display panel 61 is substantially the same as that of the first housing wall area 21 , both of which are tilted. The top of the first shell wall area 21 relative to the height direction H of the double-gallbladder air fryer is at least 45 mm lower than the top wall 27 .

The cooling fan 72 rotates to form a cooling cycle between the outside world and the installation cavity S and the cooling cavity L. Referring to FIGS. 4 and 6 , the cooling cycle is represented by a dotted arrow. Specifically, the cooling wind from the outside world (i.e., the outside world The natural wind in the environment (hereinafter also referred to as cooling wind) passes through the first air inlet 31 and enters the installation cavity S. Driven by the rotation of the cooling fan 72, it enters the cooling cavity L connected to the installation cavity S, and then It is discharged to the outside through the first air outlet 32 , thus forming a cooling cycle. Because the first air inlet 31 is located at the bottom side of the display panel assembly 60 , the cooling cycle must pass through the bottom of the display panel assembly 60 , thereby affecting the display panel assembly 60 . Better cooling avoids the serious problem of overheating of the display panel 61 in the double-gallbladder air fryer 100.

For the structure of the upper casing 20, for example, reference can be made to Figures 3 and 6. The upper casing 20 also includes a top wall 27. The side walls 25 of the upper casing 20 are surrounded by the top wall 27, and the second air inlet 26 surrounds the top wall. Wall 27 is set.
