Incorporated by reference to the refrigerator that Fig. 1, embodiment of the present invention are provided, including refrigerating chamber 60, the lower section of refrigerating chamber 60 is set
There is magazine, the evaporator 2 of cold air in cooling refrigerator is provided with the reverse side of refrigerating chamber 60, set around evaporator 2
There is the cool-air duct 50 for circulating cold air, pressure fan is provided with the cool-air duct 50 of the side of above-mentioned refrigerating chamber 60, be used for
To transporting cold-air in refrigerator, the rear of the pressure fan is provided with guard mechanism 1, for controlling in above-mentioned cool-air duct 50
Cold air passes through, and the above-mentioned structure of machine 1 that blocks is in the cool-air duct 50.
In the present invention, the guard mechanism 1 includes baffle plate and control device, and the control device is used to control the gear
Plate is moved, and is used to control whether the cold air in cool-air duct 50 passes through.Specifically, the control device control the shutter to
One side shifting, makes the baffle plate cover the pressure fan, prevents the cold air in cool-air duct 50 from passing through, or control device control
The baffle plate, to expose the pressure fan, passes through to a side shifting in order to the cold air in cool-air duct 50.
In our first embodiment, as shown in Fig. 2 the baffle plate includes first baffle 31 and second baffle 32, it is described
Control device is used to control above-mentioned first baffle 31 to be moved to first direction, and the second baffle 32 is moved to second direction, the
The angle that one direction and second direction are formed is 180 degree, i.e., first direction with second direction conversely, making two baffle plate into closure
State, to cover the pressure fan, prevents the cold air in cool-air duct 50 from passing through, or described two baffle plates state to be opened,
Expose the pressure fan, the cold air being easy in cool-air duct 50 passes through.
Specifically, as shown in Fig. 2 when refrigerator normal work, the first baffle 31 and second baffle 32 are to be opened
State, i.e., described first baffle 31 and second baffle 32 are dorsad moved, and the cold air in cold air path 50 passes through refrigerating chamber 60, now,
Pressure fan rotates refrigerator and normally freezes.When refrigerator defrost, as shown in figure 3, first baffle 31 and second baffle 32 are now relative
The pressure fan is moved towards, 32 one-tenth closure states of the first baffle 31 and second baffle, covers the pressure fan, evaporator
2 defrost spaces are blocked with cool-air duct 50, and the heat that defrost is generated cannot be flowed into refrigerating chamber 60 by cool-air duct 50,
The problem that temperature rises in refrigerating chamber 60 is avoided, while reducing power consumption.
In the present invention, the control device includes drive device and transmission device, and the transmission device includes chain, described
