Conversion is all contained in protection scope of the present invention.
As shown in Figure 1 to Figure 2, the preferred embodiment of the invention, the preferred embodiment discloses a kind of refrigerator 100, refrigerator
100 include casing, and casing limits two refrigeration compartments, is respectively refrigerating chamber 20 and refrigerating chamber 30, generally, refrigerating chamber
20 and refrigerating chamber 30 set from top to bottom.It is of course also possible to be three refrigeration compartments for setting from top to bottom or other constructions
Form.In the present embodiment, the direction that refrigerating chamber 20 and refrigerating chamber 30 are arranged from top to bottom is defined as the short transverse of refrigerator, user
Refrigerator is opened in face of refrigerator doors and the fore-and-aft direction of refrigerator is defined as back to the direction of refrigerator doors, perpendicular to short transverse and thickness
The definition in direction is the width of refrigerator.
Refrigerator also has evaporator 50 and blower fan 52, and evaporator 50 is arranged on the evaporator chamber 51 on the top of casing refrigerating chamber 30
Interior, blower fan 52 is arranged on the rear portion of evaporator 50 in evaporator chamber 51, and the bottom of evaporator 50 sets defroster（It is not shown）, pressure
Contracting machine 40 is arranged on the rear side of refrigerator bottom.Evaporator 50 can be known any evaporator, such as evaporator fin,
One kind in wire-tube evaporator, inflation type evaporator and plate pipe evaporator.In present embodiment, refrigerator 100 by compressor 40,
Condenser（It is not shown）Compression cooling cycle system is constituted with evaporator 50, the cold wind of flash-pot 50 is introduced freezing by blower fan 52
Room 30 and refrigerating chamber 20, blower fan 52 and lead to refrigerating chamber 30 supply air duct constitute the first air delivery duct 34, blower fan 52 and lead to it is cold
The supply air duct for hiding room 20 constitutes the second air delivery duct 22.Air channel heat-insulation layer 35 is provided with first air delivery duct 34, to reduce cold
Loss, lifts heat insulation effect.Air door is set in second air delivery duct 22, by controlling being turned on or off for air door, to realize being
It is no that refrigerating chamber 20 is freezed.During work, compressor promotes refrigerant circulation, into the refrigerant heat absorption evaporation of evaporator 50, wind
Machine 52 is sent to corresponding refrigeration compartment, i.e. cold wind and enters refrigerating chamber 30 through the first air delivery duct 34 through circulation air path, and cold wind is through second
Air delivery duct 22 is carried into refrigerating chamber 20, the i.e. refrigeration of refrigerating chamber 20 and refrigerating chamber 30 by the compression cooling cycle system of refrigerator 100
For.
In order that the cold distribution of refrigerating chamber 20 and refrigerating chamber 30 is more rationally, and it is preferred in the present embodiment, sent first
Guiding rib 53 is set between the air delivery duct 22 of air channel 34 and second, and the cold wind self- steering muscle 53 of flash-pot 50 is to the first air delivery duct 34
Shunted with the second air delivery duct 22, shunt the air quantity and the air quantity ratio to the first air delivery duct 34 of backward second air delivery duct 22 and refrigeration and
The ratio between freezing refrigerating capacity is identical.That is, the design of the refrigerator of co-content guiding rib at this is not different.In the present embodiment, lead
The projection towards blower fan 52 is configured to muscle 53, by setting the direction of projection and the angle of inclination of raised two sections
The distribution of the air quantity of the refrigeration needed for realizing refrigeration and freezing, the optimal demand air quantity for ensureing refrigerating is designed by wind path,
Cold is avoided to distribute the uneven refrigerating efficiency for causing low, simple structure distributes cold according to actual needs, cold so as to avoid
The waste of amount, more energy-conservation.
It is top-down in refrigerating chamber 30 to be provided with three drawers, i.e. upper strata drawer 31, middle level with continued reference to Fig. 1 and Fig. 2
Drawer 32 and lower floor's drawer 33, it is corresponding with three drawers in the first air delivery duct 34 there is provided three air ports, i.e., with upper strata drawer
31 corresponding upper strata air ports 341, middle level corresponding with middle level drawer 32 air port 342, with the corresponding lower floor air port of lower floor drawer 33
343, the cold wind into the first air delivery duct 34 can respectively enter three drawers from three air ports, then from the anterior return air of drawer to
Evaporator 50.Roof-packed evaporator, hot gas is typically walked upwards during defrost, therefore, refrigerator of the evaporator positioned at rear portion is compared to, change
The hot gas that refrigerating chamber is entered into when white is less, therefore defrost temperature rise is small, defrost good constant-temperature effect.
With reference to shown in Fig. 3 and Fig. 4, the first air delivery duct 34 is configured to tapering type air channel wide at the top and narrow at the bottom, it is preferred that first send
The cross-sectional configuration in air channel 34 for step type, stepped air channel from top to bottom include three sections of wind paths of upper, middle and lower, i.e. epimere wind path 345,
Stage casing wind path 346 and hypomere wind path 347, three sections of height dimension ratios of wind path are epimere 60%-70%, stage casing 30%-40%, hypomere
10%-20%, the height dimension ratio of certain three sections of wind paths can also be arranged to identical with the height ratio of three drawers.In addition,
The width in three air ports is also configured to consistent with the width of three sections of wind paths, and the air port area ratio in three air ports is also configured to and three
The width ratio of Duan Fenglu is identical, in combination with air quantity and temperature test such that it is able to ensure cryogenic temperature uniformity.By gradually
Contracting formula Duct design, reasonable distribution cold, it is to avoid cold wastes that the temperature fluctuation that causes is big and not energy-conservation.
Certainly, stepped tapering type air channel is the one kind in tapering type air channel, can also be plagiohedral, curved etc.
Size and area Deng, three air ports can also correspond to the volume of three drawers and be allocated.
It should be understood that, although the present specification is described in terms of embodiments, but not each implementation method only includes one
Individual independent technical scheme, this narrating mode of specification is only that for clarity, those skilled in the art will should say
Used as an entirety, technical scheme in each implementation method can also be through appropriately combined, and forming those skilled in the art can for bright book
