[0028] Figure 1 The figure is a cross-sectional view of the cooking device of the embodiment of the utility model. In the embodiment, the ventilation structure is installed on the cooking device, and is particularly suitable for the cooking device that uses hot air to heat food. When the cooking device is working, the hot air used to heat the food and the cold air from the outside are exchanged and circulated through the ventilation structure. In the cooking device, the hot air is generated by the heating device. Figure 1As shown, the heating device comprises a top cover assembly 1, in which an inner cover 6 is installed. A ventilation structure 5 is fixed on the inner cover 6 and is located on one side of the top cover assembly 1.
[0029] Figure 2 for Figure 1 The structure shown is a three-dimensional diagram after removing the top cover assembly. Figure 1 , Figure 2 As shown, the ventilation structure 5 includes an air inlet 11 and an air outlet 12. Figure 2 It can be seen that in this embodiment, the air inlet 11 and the air outlet 12 are both located on the side wall of the top cover assembly 1, and the air inlet 11 and the air outlet 12 are both arranged on the same side of the top cover assembly 1.
[0030] Figure 3 For along Figure 2 The overall cross-sectional view of the cooking device after cutting through the A-A' line. Figure 3 As shown, the air inlet 11 is equipped with a guide air according to Figure 3 The direction of the middle arrow C enters the first guide element of the first space from below. The first space is between the top cover assembly 1 and the inner cover 6. The cold air from the outside enters the first space from the air inlet 11.
[0031] Figure 4 For along Figure 2 The overall cross-sectional view of the cooking device after the B-B' line is cut. Figure 4 As shown, the air outlet 12 is equipped with a guide air according to Figure 4 The second guide element of the second space is discharged upward in the direction of the middle arrow D. The second space is in the inner cover 6.
[0032] The first space and the second space are connected through the ventilation holes of the inner cover 6. When the heating device is working, the first guide element of the air inlet 11 is more likely to inhale cold air relatively located at the bottom. After the cold air enters the first space, it passes through the ventilation holes of the inner cover 6 and enters the second space. After being heated, it is blown toward the food by the fan blade assembly of the second space to cook the food. After the hot air circulates in the cooking equipment, it is discharged upward from the air outlet 12 of the second space to the outside. The hot air itself is relatively light and will quickly rise to a relatively upper position. Since the air directions guided by the first guide element and the second guide element are different, it is possible to effectively avoid the cold air and the hot air from being mixed during the circulation, thereby improving the air circulation efficiency and the overall heating efficiency of the cooking equipment.
[0033] Specifically, the first guiding element is a multi-row plate-like structure inclined upward from the outside of the first space to the inside of the first space, and the second guiding element is a multi-row plate-like structure inclined downward from the outside of the second space to the inside of the second space. Figure 5 for Figure 2 Another angle diagram of the diagram. Figure 5As shown, in this embodiment, the first guide element and the second guide element are both plate-shaped louver structures. It can be understood that as long as the air can be guided, the first guide element and the second guide element can also be plane structures or curved structures of other shapes.
[0034] Since the ventilation structure 5 of this embodiment can effectively avoid the mixing of hot air and cold air in the air circulation, Figure 2 and Figure 5 As shown, the air inlet 11 and the air outlet 12 can be arranged on the same side of the top cover assembly 1. Figure 5 As shown, the ventilation structure 5 includes an outer frame. A longitudinal partition bar is arranged in the outer frame. The first side of the partition bar is an air inlet 11. The second side of the partition bar is an air outlet 12. The air outlet 12 is fixed to the inner cover 6 and communicates with the second space in the inner cover 6 so as to discharge the hot air in the second space. The outer frame is arranged as a whole on the side wall of the top cover assembly 1, and the air inlet 11 is communicated with the first space. In this way, the ventilation structure 5 can be installed on the side wall of the top cover assembly 1 as a whole more easily and quickly.
[0035] Figure 6 for Figure 2 Schematic diagram of the gas inflow and exhaust direction in the ventilation structure shown in FIG. Figure 6 It can be seen more intuitively that even if the air inlet 11 and the air outlet 12 are installed on the same side of the side wall of the top cover assembly 1, cold air enters the first space from the direction of arrow C and hot air is discharged from the second space from the direction of arrow D, which can ensure that they do not interfere with each other.
[0036] Combination Figure 1 to Figure 6 Further, a fan blade assembly is installed in the inner cover 6. The second space includes a cold air zone and a hot air zone separated by a partition. The fan blade assembly includes an upper fan blade 4 installed in the cold air zone and a lower fan blade 7 installed in the hot air zone.
[0037] The motor 3 is installed in the first space. The drive shaft of the motor 3 passes through the inner cover 6 and the partition. The upper wind blade 4 and the lower wind blade 7 are both installed on the drive shaft of the motor 3. The circuit board 2 is also installed in the first space. The motor 3 and the circuit board 2 are both installed in the first space where the cold air is sucked in. The lower temperature can ensure the normal operation of the circuit board 2 and the motor 3. A heating pipe 8 is arranged below the lower wind blade 7.
[0038] When the cooking device is working, the circuit board 2 controls the motor 3 to work, and the motor 3 drives the upper blade 4 and the lower blade 7 to rotate at the same time. The cold air from the outside enters the first space between the top cover assembly 1 and the inner cover 6 through the air inlet 11, and enters the second space in the inner cover 6 through the ventilation holes on the inner cover 6. The upper blade 4 rotates to blow the air from the cold air area into the hot air area through the partition, and the lower blade 7 blows the air and blows it downward after being heated by the heating tube 8 to heat the food below. After the air heats the food, it circulates and rises back into the inner cover 6 and is discharged from the air outlet 12.
[0039] In this embodiment, a cooking device equipped with the ventilation structure 5 is also disclosed, the cooking device comprising a food placement space and a heating device located above the food placement space. The heating device comprises a fan assembly, and the fan assembly blows hot air downward to the food placement space.
[0040] When the cooking device is an air fryer, the cooking device further includes a bottom cover assembly 9. The food placement space is between the heating device and the bottom cover assembly 9. The food placement space also includes an oil receiving bucket assembly 10 that can be withdrawn from the side of the food placement space. It can be understood that the cooking device can also be an oven assembly that uses a similar principle to heat food.
[0041] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0042] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
