Specifically, when the support base surface of the electric appliance is a horizontal surface, the center axis S is parallel to the horizontal direction and the center axis S is directed from the front side of the electric appliance to the rear side or from the rear side of the electric appliance to the front side.
As shown in fig. 5, the air duct member 100 of the present invention can be divided into an upper air duct structure 101 and a lower air duct structure 102, which are arranged in a central symmetry manner about a central axis S and mainly function to guide the air flow; the problems of uneven air outlet, smaller air outlet amount and poorer comfort of the cabinet air conditioner with upper and lower air outlets in the prior art are solved. The upper air duct structure 101 and the lower air duct structure 102 are completely the same, so that generalization can be realized, the types of parts required by the air duct components are reduced, the assembly efficiency of the air duct components is improved, the possibility of wrong assembly of the air duct components on an assembly line is reduced, the parts of the air duct components are more compact, and the space occupancy rate of the air duct components is reduced.

Compared with the scheme that the air outlet of the air duct component of the air conditioner in the prior art needs to be guided by the air guide plate to realize 90-degree steering, the inclined arrangement of the rotating axes of the fan blades in the first fan 13 and the second fan 14 ensures that the angle required to be rotated when the air flow flows out of the air duct component is smaller, the air flow steering mutation of the air conditioner during up-and-down air outlet is reduced, the air outlet smoothness is improved, and the noise generated during air outlet is reduced.
Preferably, the second predetermined angle is in the range of 5 ° to 20 °. The second predetermined included angle may be equal to or different from the first predetermined included angle.
It is further preferable that the rotation axis L1 of the first fan 13 and the rotation axis L2 of the second fan 14 are disposed at a second predetermined included angle with respect to a second predetermined plane B, wherein the included angle between the rotation axis L1 of the first fan 13 and the second predetermined plane B may be equal to or different from the included angle between the rotation axis L2 of the second fan 14 and the second predetermined plane B.

Because the air inlet scope of wind channel part is bigger, the detection precision of electrical equipment's temperature sensing package also can be more accurate, and the air inlet amount of wind receives the influence of wall body or other furniture etc. of electrical equipment's rear side just also littleer, has better air inlet effect.
When the electrical equipment is an air conditioner, under the refrigeration working condition, due to the sinking characteristic of cold air flow, cold air is mainly sucked by the first fan 13 through the evaporator and is exhausted from the upper side to the front side of the electrical equipment, so that the refrigeration comfort experience of a user is improved; under the heating condition, due to the floating property of the hot air flow, the hot air is mainly sucked by the second fan 14 through the evaporator and is discharged from the lower side of the electrical equipment to the front side, so that the heating comfort experience of a user is improved.

Compared with the first embodiment, the second embodiment further avoids the condition that the air inlet area of the first fan 13 and the air inlet area of the second fan 14 are overlapped, increases the air inlet range and the air inlet amount of the air duct part, and improves the utilization rate of the evaporator.
Preferably, the fourth predetermined angle is in the range of 5 ° to 20 °. The fourth predetermined included angle and the second predetermined included angle may be equal or unequal.
