As shown in Figures 1 to 4, the present invention provides a kind of double air door refrigerators, it includes babinet 10, is installed in babinet 10
The control device of ducting assembly 20 and the control ducting assembly 20.
The ducting assembly 20 include heat-insulated cavity, the evaporator 22 that is installed in the heat-insulated cavity and wind turbine 23, with
And air inlet 24 and air outlet 25 arranged on the heat-insulated cavity both ends.
The heat-insulated cavity is made of heat preserving and insulating material, it is equipped with a pair of side wall 210 being parallel to each other and from side wall 210
Inward at both ends extension arcwall 211, the side wall 210 and arcwall 211, which are collectively forming, accommodates the evaporator 22 and wind
The accommodating chamber 212 of machine 23, and the air inlet 24 at the heat-insulated cavity both ends and air outlet 25 are respectively communicated with the accommodating chamber 212,
As shown in Figure 1, the air inlet 24 in be equipped be disposed adjacent and it is independent of each other refrigeration shutter 241 and freezing shutter 242,
And the refrigeration shutter 241 can be independently turned on and off with the freezing shutter 242, in present pre-ferred embodiments,
The air inlet 24 sets forked two air intake passages A, B, and the refrigeration shutter 241 and freezing shutter 242 are pacified respectively
Loaded in described two air intake passages A, B.It is equipped with the air outlet 25 and is disposed adjacent and independent of each other refrigerates out air door 251
With freeze out air door 252, it is described to refrigerate out air door 251 and refrigeration 241 in the vertical direction of shutter corresponds setting,
It is described freeze out air door 252 and it is described freezing 242 in the vertical direction of shutter correspond setting.
The evaporator 22 is located at the center of the accommodating chamber 212, and between the air inlet 24 and air outlet 25,
And the both sides of evaporator 22, by 210 enclosing of side wall, the evaporator 22 is located at the top of the air inlet 24 and is located at institute
State the lower section of air outlet 25.The wind turbine 23 is between the air outlet 25 and evaporator 22, and the both sides of wind turbine 23 are equipped with
The arcwall 211.During operation, under the drive of wind turbine 23, the air-flow in the heat-insulated cavity will flow at air inlet 24
Air outlet 25, and go out air door 251 and freeze out air door 252 to flow out from the refrigeration at air outlet 25, it is described to refrigerate out 251 He of air door
Freeze out air door 252 and be respectively used to the cold that refrigerating chamber R1 and refrigerating chamber R2 are led in control.
As shown in figure 3, the control device connects and controls the compressor R3 of the refrigerator, the wind turbine 23, described cold
Shutter 241, the freezing shutter 242 are hidden, described air door 251 refrigerated out and described freezes out air door 252, and the control
Device is connected with the temperature sensor in refrigerating chamber R1 and refrigerating chamber R2 respectively, can be obtained in real time in refrigerating chamber R1 and refrigerating chamber R2
Temperature data, and the startup of compressor R3 and closing are controlled according to the temperature data.
In addition, the present invention also provides a kind of control method of double air door refrigerators, including：
The temperature in refrigerating chamber R2 and refrigerating chamber R1 is monitored, and the wind in heat-insulated cavity is defaulted according to monitoring result control
The air inlet 24 and air outlet 25 of machine and the heat-insulated cavity, wherein, by monitors temperature, wind is controlled by control device
The opening and closing of machine 23, air inlet 24 and air outlet 25；
When the temperature of refrigerating chamber R2, refrigerating chamber R1 reach default turn-on temperature value, the pressure is controlled by control device
Contracting machine R3 starts to start to freeze, and individually opens in freezing shutter 242 and the air outlet 25 in the air inlet
Air door 252 is freezed out, at this time, compressor R3 keeps upper frequency operating（Make evaporating temperature≤- 18 DEG C）, pass through the wind turbine 23
Operating the cold at evaporator 22 is sent to refrigerating chamber R2；
When refrigerating chamber R2 temperature reaches default shutoff temperature value, the freezing shutter 242 is closed by control device
With freeze out air door 252, and open at the same time in the air inlet 24 refrigeration shutter 241 and the air outlet 25 in refrigeration
Go out air door 251, at this time, compressor R3 keeps lower frequency operating, makes evaporating temperature close to refrigeration design temperature, the compressor
The refrigerating efficiency of R3 increases when relatively freezing refrigeration.
When the temperature of refrigerating chamber R1 reaches default shutoff temperature value, the compressor R3 and institute are closed by control device
State refrigeration shutter 241 and refrigerate out air door 251, thus complete a kind of refrigeration cycle.
It is cold therefrom as it can be seen that what the process of refrigerastion of refrigerating chamber R2 of the present invention and refrigerating chamber R1 independently can be carried out separately
When hiding refrigeration, list is only needed when only need to individually open the refrigeration shutter 241 and refrigerate out air door 251, and freeze refrigeration
Solely open the freezing shutter 242 and freeze out air door 252, two processes do not interfere with each other, and can be filled by controlling
Put and be independently controlled, realize to the reasonable of cold, science distribution.
Simultaneously as the evaporator 22 and wind turbine 23 are arranged in the heat-insulated cavity, soundproof effect has been lifted, and
And when opening refrigeration shutter 241 and refrigerating out air door 251 and individually carry out refrigeration, cold will be via refrigerating out air door
251 are delivered in refrigerating chamber R1 to replace out the air-flow that temperature is higher in refrigerating chamber R1, at this time just with compressor R3 low frequencies
Evaporator 22 during operation carries out cold and hot exchange, realizes the defrost carried out to evaporator 22, and such a defrost mode is refrigerating every time
It can all be carried out during refrigeration, frost layer thick and heavy on traditional air cooling refrigerator evaporator 22 will not be formed, improve heat exchange effect
Rate, and heating tube need not be installed additional, thus high-temperature gas will not be produced during defrost, the temperature of each chamber of refrigerator will not be caused
Degree rise, the security performance of refrigerator are also more preferable.Further, since refrigeration and defrost are carried out at the same time, humidity in white melting process
It is larger, moreover it is possible to increase air humidity.
In conclusion it is of the invention by being placed in evaporator 22, wind turbine 23 in the heat-insulated cavity made by thermal insulation material, and
Two air doors are installed additional respectively in air outlet 25 and air inlet 24 above and below cavity, for being allocated to cold, refrigerating chamber R1,
Refrigerating chamber R2 inlet airs and return air heat defrosting device at evaporator 22 all by airdoor control without setting, in refrigerating chamber R1
During reaching cryogenic temperature closing, cold air and pressure in case can be kept, refrigerating efficiency is improved, beneficial to energy saving.
It should be appreciated that although the present specification is described in terms of embodiments, not each embodiment only includes one
A independent technical solution, this narrating mode of specification is only that those skilled in the art will should say for clarity
For bright book as an entirety, the technical solution in each embodiment may also be suitably combined to form those skilled in the art can
With the other embodiment of understanding.
Those listed above is a series of to be described in detail only for feasibility embodiment of the invention specifically
Bright, they simultaneously are not used to limit the scope of the invention, all equivalent implementations made without departing from skill spirit of the present invention
