Thus, the second air duct 164 can effectively reduce the temperature in the door 20 and the cavity 10 by the flowing of the air flow, thereby prolonging the service life of the household appliance 100 and improving the stability and safety of the household appliance 100 during operation.

Specifically, referring to fig. 5, the first air duct 22 may be disposed in the door 20, and the second air duct 164 may be disposed in the air duct 16. A fan 162 may be disposed within the air duct member 16. In this embodiment, the first duct 22 may be an air inlet duct, and the external cold air may enter the first duct 22 from the bottom of the door 20. The fan 162 rotates rapidly, so that negative pressure is formed in the first air duct 22, and cold air at the bottom of the door 20 is sucked into the first air duct 22. Since the air flow at the first air duct 22 is a cool air flow from the outside, the first air duct 22 can also be a cool air channel. When the external cold air flows through the first air duct 22, the cold air in the first air duct 22 can effectively reduce the temperature of the door body 20, so that the temperature rise of the glass door of the door body 20 can be greatly reduced by the cold air in the first air duct 22, and the damage caused when a user touches the door body 20 with an excessively high temperature is avoided.

The second air duct 164 may be an air outlet duct. The air duct member 16 with the second air duct 164 can be connected to the top of the cavity 10, and during the operation of the household electrical appliance 100, the hot air flow emitted around the cavity 10 can flow into the second air duct 164, at this time, since the first air duct 22 is communicated with the inlet 1642 of the second air duct 164, the cold air in the first air duct 22 can flow to the second air duct 164, and both the cold air flow and the hot air flow in the second air duct 164, so that the cold air flow can effectively reduce the temperature of the hot air flow. Moreover, since the outlet 1644 of the second air duct 164 is connected to the gap between the top of the door 20 and the control box 13, the air flow can be discharged out of the household appliance 100 through the gap between the top of the door 20 and the control box 13. Thus, the second air duct 164 can be used for dissipating heat of the household appliance 100, and therefore the second air duct 164 can also be a heat dissipating channel. The second air duct 164 can effectively reduce the temperature inside the household appliance 100 and take away heat, so that the environmental temperature of the electric device and the electric control is at a proper temperature, thereby prolonging the service life of the household appliance 100 and improving the stability and safety of the household appliance 100 during operation.

In certain embodiments, the second air plenum 164 includes spaced upper and

lower air passages

1646, 1648. The air duct member 16 includes a connecting space 1647 communicating the upper air duct 1646 and the lower air duct 1648. The fan 162 is located in the connecting space 1647. The lower air duct 1648 communicates with the first air duct 22. The upper duct 1646 communicates with a gap between the top of the door body 20 and the control box 13. So, because second wind channel 164 separates into two wind channels, avoid the interact of air inlet and air-out, guarantee the stable flow of air current.

Specifically, referring to fig. 5, the arrows in the figure may be the flow direction of the airflow. The second air duct 164 may be a bidirectional air duct, which is an upper air duct 1646 and a lower air duct 1648, the upper air duct 1646 and the lower air duct 1648 are spaced apart from each other, a connecting space 1647 is provided to connect the upper air duct 1646 and the lower air duct 1648, a fan 162 may be provided in the connecting space 1647, in this embodiment, the fan 162 may be a vortex fan 162, and during the operation of the household appliance 100, the first air duct 22 is communicated with the lower air duct 1648, the air flow of the first air duct 22 may flow into the lower air duct 1648, pass through the fan 162 at the connecting space 1647, and be driven to flow by the rotation of the fan 162, the air flow can then enter the uptake 1646, the air flow can flow in the uptake 1646, because the upper air duct 1646 is communicated with the gap between the top of the door body 20 and the control box 13, the air flow at the upper air duct 1646 can flow to the gap, and then discharged to the outside of the home appliance 100 from the gap, thereby realizing circulation of air flow in the home appliance 100 and improving the heat dissipation effect of the home appliance 100.
