Lower layer space in be provided with compressor 7 and condenser 8, air channel 3 is provided with the upper sheaf space of base 1, provided with drive in the air channel 3
The blower fan 5 and evaporator 5 for body circulation of taking offence, the air-flow in air channel 3 that the air inlet anterior from air channel 3 enters, flow through evaporator 5
Carry out heat exchange and be changed into cold air.
In the present embodiment, cold air circulating structure includes air channel 3 and three guide ducts 9 being located in cabinet 2, guide duct 9 with
The air outlet connection in air channel 3, guide duct 9 is vertically arranged, and some the first exhaust vents blown forward are offered on guide duct 9
91.It is connected by guide duct 9 with the air outlet in air channel 3, can be defeated along guide duct 9 by the cold air of the air outlet blowout from air channel 3
Send；Guide duct 9 is vertically arranged, can be delivered up cold air in cabinet；And offer and some blow forward on guide duct 9
The first exhaust vent 91, the first exhaust vent 91 along guide duct 9 short transverse distribution so that under cold air can reach in cabinet
Portion, middle part, top, add the uniformity that cold air is distributed on the above-below direction in cabinet；Blown from some first exhaust vents 91
The cold air flow forward gone out, be advantageous to the flowing of cold air from back to front, increase cold air is uniform in cabinet 2, improves refrigeration effect
Rate, and the air inlet 31 in the air channel 3 through the top nose of base 1 flows back to air channel, forms the circulation of cold wind.
In the present embodiment, referring to shown in Fig. 2, Fig. 3, Fig. 6, pass through bottom rack 61, middle level rack in cabinet 2
62 and upper strata rack 63 form it is corresponding with each layer rack put object space, guide duct 9 is located at the rear portion of cabinet 2, put
Rack is arranged on the postnotum of cabinet 2, and the corresponding each layer rack of multiple first exhaust vents 91 opened up on guide duct 9 opens up.
Specifically, object space is put for bottom rack 61 between bottom rack 61 and middle level rack 62, in guide duct 9 in bottom
Putting for rack 61 offers multiple first exhaust vents 91 in object space, the cold wind of these first exhaust vents 91 blowout is put along bottom
The object space of putting of rack 61 flows from back to front, forms the flowing put object space in of the cold air in bottom rack 61；Similarly,
Object space is put for middle level rack 62 between middle level rack 62 and upper strata rack 63, in guide duct 9 in middle level rack
62 put also offers multiple first exhaust vents 91 in object space, the cold wind of these first exhaust vents 91 blowout is along middle level rack
62 object space of putting flows from back to front, forms the flowing put object space in of the cold air in middle level rack 62；Upper strata rack
Object space is put for upper strata rack 63 between 63 and the top of cabinet 2, object space is put in upper strata rack 63 in guide duct 9
Multiple first exhaust vents 91 are inside also offered, the cold wind of these first exhaust vents 91 blowout puts object space along upper strata rack 63
Flowing is uniform from back to front, forms the flowing put object space in of the cold air in upper strata rack 63.It is this ensure that air-cooled each
Distribution on layer rack, increase cold air in cabinet 2 and be evenly distributed, and improve refrigerating efficiency.
In the present embodiment, the top of guide duct 9 is connected with the top of cabinet 2, and the top of guide duct 9 is closing.Referring to
Shown in Fig. 6, the size of multiple first exhaust vents 91 opened up in the short transverse of guide duct 9 is identical, but is opened in and leads
The air output of the first exhaust vent 91 on the different height of airduct 9 is certainly different；Due to the cold air flow direction in guide duct 9
To be upward, and it is the first higher exhaust vent 91 of height on guide duct 9 in the case of being closing on the top of guide duct 9
Air output is bigger.In order that being uniformly distributed in object space must be put in each layer through the cold blast rate after guide duct 9, from bottom to top
Each layer rack put in object space, the quantity of the first exhaust vent 91 being opened on guide duct 9 gradually decreases；So by opening
If the quantity of the first exhaust vent 91 it is different, ensure that reaching the cold blast rate for respectively putting object space is close, and further ensures in cabinet 2
Cold air it is uniform, that is, temperature in cabinet 2 is uniform, improves refrigerating efficiency.
In the present embodiment, three guide ducts 9 are arranged as in cabinet 2：Two guide ducts 9 are located at the left and right in cabinet 2
Both sides and a guide duct 9 are positioned at centre.In order that cold wind in the lateral direction uniform, offered on guide duct 9
Some the second exhaust vents 92 blown to the left and/or to the right.Open up second exhaust vent 92 and be advantageous to cold air in the lateral direction
Uniformly, the first exhaust vent 91 from back to front when blowing, air-flow can spread to the left and right, but be led at the rear portion of cabinet 2 at two
Position between airduct 9, the cold air of the first exhaust vent 91 blowout can not reach；The second exhaust vent 92 is set mainly to go out with first
Air holes 91 is engaged, by cold air in cabinet 2 it is uniform, blown to the left or to the right from the cold air of the second exhaust vent 92 blowout, and
Flow forward under the drive of the air-flow of first exhaust vent 91 blowout.Preferably, guide duct 9 is rhs-structure, before guide duct 9
The first exhaust vent 91 is offered on face, the second exhaust vent 92 is offered on the left and right side of guide duct 9.Among in cabinet 2
Guide duct 9 on the left and right sides offer the second exhaust vent 92, on 9 one sides of guide duct of the left and right sides
Offer the second exhaust vent 92.
In the present embodiment, for the second opening up in upper-lower height of exhaust vent 92 on guide duct 9, and with the first air-out
The identical principle of hole 91, the size of multiple second exhaust vents 92 is identical, and some second exhaust vents 92 on guide duct 9 are located respectively
In putting in object space for each layer rack；And in putting in object space for each layer rack from bottom to top, it is opened in guide duct 9
On the quantity of the second exhaust vent 92 gradually decrease.
Shown in Figure 7 in the present embodiment, air channel 3 includes the branch air outlet 32 corresponding with the quantity of guide duct 9,
It is exactly that there are three branch's air outlets 32, the lower end of guide duct 9 is tightly connected with branch air outlet 32；In three branch's air outlets
Branch air channel 33 between 32 and evaporator 5, cold wind after the heat exchange for so evaporator 5 being flowed through in air channel 3 while is flowed into
Three branch air channels 33, and three guide ducts 9 are supplied to, and then be transported in cabinet 2, and the air inlet 31 through air channel 3 returns again
Into air channel 3, a cold wind circulation is completed.The cold wind after the heat exchange of evaporator 5 is flowed through in air channel 3 and is divided into three parts, point
The area sum of air intake vent and the going out for evaporator 5 in three branch air channels 33 Liu Ru not be preferably provided with three branch air channels 33
The area in wind face is identical.
In the present embodiment, branch air channel 33 is pyramidal structure, that is, in the flow direction top set air channel 33 of air-flow
Sectional area is gradually reduced, and is so advantageous to increase the air pressure at branch's air outlet 32, increase flows through the stream of the cold air of guide duct 9
Speed, and the flow velocity of the gas blown out through the first exhaust vent 91 and the second exhaust vent 92, are advantageous to improve refrigerating efficiency.
It is described above, only it is preferred embodiment of the present utility model, is not that other forms are made to the utility model
Limitation, any person skilled in the art is changed or is modified as possibly also with the technology contents of the disclosure above equivalent
The equivalent embodiment of change.But it is every without departing from the content of the technical scheme of the utility model, it is real according to technology of the present utility model
Any simple modification, equivalent variations and the remodeling that confrontation above example is made, still fall within the guarantor of technical solutions of the utility model
Protect scope.
