Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1-11, an air fryer with efficient cold air circulation comprises a housing, wherein the housing comprises an upper housing 1 and a lower housing 2, the upper housing 1 is provided with an upper air inlet, and the upper air inlet is generally arranged on the upper end surface of the upper housing 1 and can be arranged at other positions of the upper housing 1. The lower shell 2 is provided with a lower air inlet, the lower air inlet is generally arranged on the lower end surface of the lower shell 2, and can be arranged at other positions of the lower shell 2.
The inner container 3 is arranged in the lower shell 2, the air guide cover 4 is arranged in the upper shell 1, a window for blowing out cold air and hot air is formed in the air guide cover 4, an air outlet 6 corresponding to the window is formed in the upper shell, a grid 7 can be arranged on the air outlet, and the air-conditioner is more attractive and safer. A lower cold air interlayer 8 is formed between the lower shell 2 and the inner container 3, an upper cold air interlayer 9 is formed between the upper shell 1 and the air guide cover 4, and the upper cold air interlayer 9 and the lower cold air interlayer 8 are communicated with each other.
The air guide cover 4 is internally provided with a heat insulation cover 10, the heat insulation cover 10 divides the air guide cover 4 into an upper cold air cavity and a lower hot air cavity, an electric heating device 11 is arranged in the hot air cavity, the electric heating device 11 is generally an electric heating tube, and other electric heating devices can be adopted.
The air guide cover 4 is provided with a driving motor 12, and the output end of the driving motor 12 is connected with a cooling fan 13 and a hot fan 14. The driving motor 12 is generally composed of a motor and a reducer, but the motor may be used alone. The output end of the driving motor 12 is an output shaft, and the cooling fan 13 and the hot air fan 14 are preferably coaxially arranged on the output shaft.
The cooling fan 13 is located in the cooling air cavity, when the cooling fan 13 works and rotates, external cooling air is sucked into the cooling air cavity through the upper air cooling interlayer 9 and the lower air cooling interlayer 8 and is finally discharged from the upper portion of the window, so that the shell is cooled through the cooling air, and the temperature of the shell is prevented from being too high. As shown in FIG. 9, the cooling fan 13 may be a blade fan 13-1 or a turbofan 13-2.
The hot air fan 14 is positioned in the hot air cavity, when the hot air fan 14 works and rotates, hot air is blown into the inner container 3, the heat insulation cover 10 is provided with a hot air outlet 15, and the hot air is finally discharged from the lower part of the window through the hot air outlet 15.
An air duct wall 16 is annularly arranged on the upper end face of the air guide cover 4, and the air duct wall 16 is provided with a cold air outlet 17 aligned with the upper part of the window. The upper end surface of the wind guide cover 4 is further provided with a plurality of wind guide ribs 18 which are surrounded by the wind channel wall 16 and are arranged at intervals, and in the up-and-down projection direction, the wind guide ribs 18 are arranged around the cooling fan 13, so that the cold wind in the cold wind cavity flows to the cold wind outlet 17 under the guidance of the wind guide ribs 18. The optimal setting positions of the cooling fan 13 are as follows: the cooling fan 13 is surrounded by the air guiding ribs 18, that is, the cooling fan 13 is located in the space included by the air guiding ribs 18, and the cooling air sucked by the cooling fan 13 can be guided by the air guiding ribs 18 to the maximum extent. The air guiding ribs 18 reduce the loss caused by that the air blown out by the rotation of the cooling fan 13 vertically impacts the inner air guiding cover 4, reduce the loss of the cooling air flow and achieve the purpose of maximum air outlet quantity. Meanwhile, the air duct wall 16 and the air guide ribs 18 guide the cold air flow, so that the cold air is discharged more smoothly.
In order to achieve a better guiding effect on the cold air, the air guiding ribs 18 are arranged obliquely, so that the arrangement of the air guiding ribs 18 further follows the air flow direction of the cold air. Preferably, the air guiding ribs 18 are arc-shaped, and the concave arc surfaces of the air guiding ribs 18 face inwards, so that the guiding direction of the air guiding ribs 18 to the cold air is basically consistent with the flowing direction of the cold air sucked by the cooling fan 13, and the guiding effect to the cold air is stronger.
In this embodiment, a wind shielding rib 19 for preventing blown cold wind from flowing back to the cold wind chamber is further disposed at the cold wind outlet 17, the wind shielding rib 19 is located at the wind inlet side of the wind guiding rib 18, for example, as shown in fig. 9 and 10, when the rotation direction of the cooling fan 13 is clockwise rotation, the cold wind enters from the right side in the figure and is guided by the wind guiding rib 18 and the wind channel wall 16 to be discharged, and at this time, the wind shielding rib 19 is located at the right side of the cold wind outlet in the figure.
In this embodiment, the cold air outlet 17 is further connected with an air outlet channel 5, and the air outlet channel 5 forms the window. A partition plate 20 is arranged in the air outlet channel 5 so as to divide the air outlet channel 5 into an upper channel and a lower channel, the upper channel corresponds to the cold air outlet 17, and the lower channel corresponds to the hot air outlet 15. After the partition plate 20 is arranged, the cold air outlet and the hot air outlet are separated by the partition plate 20, so that the cold air and the hot air are prevented from flowing.
In this embodiment, a wind shielding plate 21 is further disposed in the cold air cavity, and the wind shielding plate 21 is located between the cooling fan 13 and the heat insulating cover 10. Because the heat shield 10 is generally in a special shape, cold air in the cold air cavity can move downwards to the position below the cooling fan 13, power is lost, air outlet is not smooth, cold air circulation is affected, after the wind shield 21 is arranged, downward loss of air flow can be greatly reduced, power of cold air outlet is kept, and smoothness of cold air outlet is guaranteed. The wind shield 21 in this embodiment extends to be connected to the side wall of the wind scooper 4, so as to completely block the cold wind.
