Freezing air -return duct (not shown) and the connection alternating temperature return air inlet 31 and the alternating temperature air -return duct at second return air end 462 (are not schemed
Show).
Structure of the invention will be described further with two specific examples below:
As Figure 1-Figure 2, in the first embodiment of the present invention, the first air door 51 is offered on the demarcation plate 5, when
After i.e. temperature-changing chamber terminates refrigeration after the alternating temperature air door is closed, first air door 51 is closed to stop the blower 42 from described
31 return air of alternating temperature return air inlet.
It should be noted that in the present embodiment, after the refrigerator 100 starts refrigeration, the alternating temperature air door is opened, institute
The first air door 51 opening is stated, the cold air through the evaporator 41 refrigeration is under the action of blower 42 from 45 edge of outlet air end
The supply air duct flows to freezing chamber 2 and temperature-changing chamber 3, under the action of the blower 42 forces driving cross-ventilation, flows to cold
The cold air for freezing room 2 is back to first return air end 461 along the freezing air -return duct from the lowermost freezing return air inlet 22, flows to
The cold air of temperature-changing chamber 3 is back to second return air end 462 along the alternating temperature air -return duct from the lowermost alternating temperature return air inlet 31, warp
Subsequent cycle is carried out after the evaporator 41 is cooling.
In the present embodiment, terminate refrigeration after the temperature-changing chamber 3 reaches the cryogenic temperature of needs, at this time by the alternating temperature
Air door and the first air door 51 are closed, and the demarcation plate 5 stops the blower 42 to the suction of the alternating temperature return air inlet 31, institute
State the no longer return air of alternating temperature return air inlet 31, therefore the temperature-changing chamber 3 not will form subnormal ambient, the higher outside air of temperature is just not
Can be entered in temperature-changing chamber 3 by the crack between a door and its frame of temperature-changing chamber 3 leads to frosting.
As Figure 3-Figure 4, in the second embodiment of the present invention, the refrigerator 100 further includes having positioned at evaporator room 4
For 42 air draught of blower, the isolation ward 47 passes through the partition and extends to second Room from the first Room 43 interior isolation ward 47
44, the blower 42 is set in the isolation ward 47.
In addition, in the present embodiment, the second air door 471 is offered on the isolation ward 47, when the alternating temperature air door is closed
Afterwards, second air door 471 is closed to stop the blower 42 to the suction of the alternating temperature return air inlet 31.
Further, in the present embodiment, the refrigerator 100 further includes air duct cover board (not shown), the isolation ward 47
It is fixedly installed on the rear side of the air duct cover board.In addition, offering connection isolation ward 47 and temperature-changing chamber 3 on the air duct cover board
Air inlet 6, the air inlet 6 are used for the blower 42 from 3 air draught of temperature-changing chamber to isolation ward 47.Also, specifically, institute
The second air door 471 is stated to be arranged close to the air inlet 6.
Second air door 471 is set to one end that the isolation ward 47 is mutually fixed with the air duct cover board.Certainly, described
The other positions that two air doors 471 are set in the isolation ward 47 also can reach the purpose of the present invention.
The difference of the present embodiment and first embodiment, which is essentially consisted in, has moved on to wind for the first air door 51 in first embodiment
It is the second air door 471 in the present embodiment on road cover board, and adds on rear side of air duct cover board the isolation ward 47 for blower
42 from 31 return air of air inlet 6 and alternating temperature return air inlet of the temperature-changing chamber 3, when the second air door 471 is closed, due to demarcation plate 5
Setting, the blower just can not be from 31 return air of air inlet 6 and alternating temperature return air inlet.
Specifically, in the present embodiment, after the refrigerator 100 starts refrigeration, the alternating temperature air door is opened, and described second
Air door 471 is opened, and the cold air through the evaporator 41 refrigeration is under the action of blower 42 from the outlet air end 45 along described
Supply air duct flows to freezing chamber 2 and temperature-changing chamber 3, under the action of the blower 42 forces driving cross-ventilation, flows to freezing chamber 2
Cold air along the freezing air -return duct be back to first return air end 461 from the lowermost freezing return air inlet 22, flow to alternating temperature
Cold air a part of room 3 is back to second return air end 462 along the alternating temperature air -return duct from the lowermost alternating temperature return air inlet 31,
Another part is back to the return air end 46 along the isolation ward 47 from the air inlet 6, laggard through the evaporator 41 cooling
Row subsequent cycle.
In the present embodiment, terminate refrigeration after the temperature-changing chamber 3 reaches the cryogenic temperature of needs, at this time by the alternating temperature
Air door and the second air door 471 are closed, and the demarcation plate 5 stops the blower 42 from 31 air draught of alternating temperature return air inlet, and institute
Stating the second air door 471 stops the blower 42 from 6 air draught of air inlet, and the alternating temperature return air inlet 31 and the air inlet 6 are not
Return air again, the temperature-changing chamber 3 would not form subnormal ambient, and the higher outside air of temperature just will not pass through the door of temperature-changing chamber 3
Seam, which enters in temperature-changing chamber 3, leads to frosting.
In conclusion the present invention is by being arranged separator between the blower in single system refrigerator and alternating temperature return air inlet to hinder
The machine that keeps out the wind farthest avoids alternating temperature ceiling to make the indoor air pressure balance of alternating temperature to the suction of alternating temperature return air inlet
Portion's frosting；Moreover, the separator used in the present invention is low in cost, food in refrigerator ensure that on the basis of not increasing energy consumption
Fresh-keeping effect.
