The specific embodiment
Below in detail with reference to preferred embodiment of the present invention, the example of described preferred embodiment is drawn in the accompanying drawings.When embodiment was described, the parts identical with current refrigerator had been given identical title and drawing reference numeral, and had omitted its more detailed description.
Illustrate below with reference to the accompanying drawings according to refrigerator of the present invention.
Fig. 1 is the front view according to refrigerator of the present invention.Fig. 2 is the front cross sectional view according to the refrigerator of the first embodiment of the present invention.Fig. 3 is the cross section view according to the refrigerator of the first embodiment of the present invention.
As shown in drawings, mainly have main body 10, refrigerating chamber 30, refrigerating chamber 40, cold air according to the refrigerator of the first embodiment of the present invention and produce equipment and cold air supply arrangement, wherein refrigerating chamber 30 and refrigerating chamber 40 are arranged at main body 10 inside.
At first, refrigerating chamber 30 is with food freezing, and refrigerating chamber 40 keeps the food cooling, so that food fresh-keeping stores.Refrigerating chamber 30 and refrigerating chamber 40 have been formed by a kind of method of cutting apart main body 10 inner spaces with dividing plate 30.
In the refrigerator according to the first embodiment of the present invention, refrigerating chamber 30 and refrigerating chamber 40 are located adjacent to each other.Optionally, refrigerating chamber 30 and refrigerating chamber 40 can be located up and down.
Cold air generation equipment is configured to produce the cold air that is discharged in refrigerating chamber 30 and the refrigerating chamber 40.And cold air generation equipment has compressor, condenser, expansion valve and evaporimeter 71.
Herein, compressor makes low temperature/low pressure gaseous coolant become the high temp/high pressure gaseous coolant, the gaseous coolant condensation that condenser will be supplied with by compressor.And expansion valve reduces the pressure of the cooling agent of being supplied with by condenser.Then, evaporimeter 71 evaporates the cooling agent that passes expansion valve under low-pressure state, to absorb heat from ambient air.Like this, ambient air has just become cold air.
As shown in Figure 3, compressor and condenser (not shown) are arranged in the Machine Room 12 of main body 10 bottoms.And it is indoor that evaporimeter 71 is arranged at another of contiguous refrigerating chamber 30 and refrigerating chamber 40.In addition, fan or air blast 72 also are arranged at the another indoor of contiguous evaporimeter 71, so that air circulates in refrigerator inside continuously.
The cold air supply arrangement is discharged to refrigerating chamber 30 and refrigerating chamber 40 with the cold air that produces in the cold air generation equipment.And the cold air feedway supplies to evaporimeter 71 with the cold air of being discharged, so that cooling once more.That is to say, the cold air supply arrangement cold air is provided continuously and in whole freezing chamber 30 and refrigerating chamber 40 (more specifically being in whole evaporimeter 71) circulate cold air, thereby respectively refrigerating chamber 30 and refrigerating chamber 40 are remained on predetermined temperature.This cold air supply arrangement can have the second supply part that first of corresponding refrigerating chamber 40 is supplied with part and corresponding refrigerating chamber 30.
Supply with part with reference to figure 2, the first and be made up of first pipeline 50 and first and second openings 51,52, described first pipeline is used for cold air is directed into refrigerating chamber 40, and the cold air that described first and second openings are used for being guided is discharged to refrigerating chamber 40.
As shown in figures 1 and 3, first pipeline 50 is connected with the chamber that is provided with for evaporimeter 71 by first intermediate openings 21 that is arranged in the dividing plate 20.Therefore, cold air is directly offered first pipeline 50 by first intermediate openings 21.First and second openings 51,52 are positioned at the upside and the side of refrigerating chamber 40, so that successfully cold air is supplied to refrigerating chamber 40.If necessary, these a plurality of first and second openings 51,52 can be arranged at refrigerating chamber 40.And second intermediate openings 22 is arranged at the downside of dividing plate 20, and wherein second intermediate openings 22 all is connected with refrigerating chamber 40 and refrigerating chamber 30.Like this, the cold air of refrigerating chamber 40 just is discharged to refrigerating chamber 30 by second intermediate openings 22.
Second supplies with part has second pipeline 60, be used for cold air is directed into refrigerating chamber 30 and evaporimeter 71, and at least one or a plurality of third and fourth opening 61 and 62 is connected with this second pipeline 60.
As shown in Figure 3, second pipeline 60 is arranged between refrigerating chamber 30 and the evaporimeter 71.Second pipeline 60 is connected with evaporimeter 71 by the 3rd intermediate openings 63, and second pipeline 60 then utilizes fan 72 to receive cold air from evaporimeter 71.The 3rd opening 61 is discharged to refrigerating chamber 30 with the cold air of second pipeline 60.The 4th opening 62 is discharged to evaporimeter 71 so that cool off this air with the cold air of refrigerating chamber 30.
In refrigerator according to the present invention, air is cooled off by fan 72 through evaporimeter 71 time.Therefore, cold air is supplied to first pipeline 50 and second pipeline 60 via first intermediate openings 21 and second intermediate openings 22.Be discharged to refrigerating chamber 30 by the 3rd opening 61 then.
Yet as above-mentioned explanation is that each separator 100 is separated at least two paths with cold air before the discharging cold air.That is to say that separator 100 is adjacent to opening 51,52,61 setting, and more specifically, is not in refrigerating chamber 30 and refrigerating chamber 40 inside, but in the inside of pipeline 50,60.According to the separation to cooling air passage, the circulation rate that reduces cold air is possible.Like this, it is exactly very useful cold air being spread to refrigerating chamber and refrigerating chamber.
And separator 100 is arranged to stop cold air, preferably, is positioned at the flow direction perpendicular to cold air, thereby cold air is separated, and simultaneously, has reduced the circulation rate of cold air.Preferably, separator 100 is formed by some flat member.Although not shown, the separator 100 that is formed by some flat member is individually fixed in the inner surface of pipeline 50 and 60.Preferably, as shown in Figures 2 and 3, pipeline 50 and 60 expands to the inside of refrigerating chamber 30 and refrigerating chamber 40, so that cold air is provided to the penetralia of refrigerating chamber 30 and refrigerating chamber 40.And opening 51,52,61 is arranged at the end of pipeline 50 and 60.Therefore, supplementary features relevant with separator 100 spread to cold air the inside of refrigerating chamber 30 and refrigerating chamber 40 highly beneficially equably.
And before discharging cold air, cold air and separator 100 bump, thereby form the turbulent flow of labile state.At this moment, turbulent flow produces some eddy current around this separator 100.More specifically, in being formed at the lip-deep laminar boundary layer of separator 100, produce negative pressure gradient so that separated cooling air passage separate at the two ends of separator 100.Described separation produces at least two eddy current A between separator 100 and opening 51,52,61, so that eddy current A respectively at the two ends of separator 100 stream in the opposite direction.This eddy current A has the shape that depends on separator 100 and the CF of scale, and also has intensity and the size that differs from one another, and changes continuously.The stream of being discharged is subjected to the disturbance of the eddy current between separator 100 and the opening 51,52,61, and with the vibration and the swing form gradually to refrigerating chamber 30 and refrigerating chamber 40 internal motions.Therefore, cold air is just spread in refrigerating chamber 30 and the refrigerating chamber 40 equably.
And, as shown in Figure 4, between separator 100 and opening 51,52,61, form two paths with separator 100.That is to say, these two paths basically toward each other, thereby the separated cold air of institute is flowed along these two paths.The effect of described path is basically as shower nozzle, be used for these two passage portion form two injection stream B.Because these two injection stream B collide relative to one another or at a predetermined angle, thereby static pressure on every side is elevated to more than the atmospheric pressure, thereby forms nonstationary flow.That is to say the eddy current A that described collision has been strengthened being produced by the separation of cold air.Like this, the cold air thermal agitation is so that cold air scatters and be provided to refrigerating chamber and refrigerating chamber equably.
And along with the time that the cold air of institute's disturbance stops in pipeline 50,60 is elongated, the vibration of cold air disappears with regard to the resistance that is subjected to owing to stream.That is to say that the dissemination efficiency for the maximum that obtains stream is necessary that the cold air that will be subjected to the maximum perturbation of eddy current A directly discharges.Therefore, opening 51,52,61 is adjacent to and produces the location, some somes place of disturbing between two eddy current A.Basically, cold air the some place of separated path be subjected to maximum disturbance, that is to say, be subjected to maximum disturbance at the some place of intersecting with injection stream B.Thus, preferably opening 51,52,61 is positioned to be adjacent to the some place of intersecting with jet B.For with due regard to, if the gap H1 between separator 100 and opening 51,52 and 61 greater than the width of opening 51,52,61, has so just produced the flow resistance for the cold air of institute's disturbance basically to above-mentioned explanation.Preferably, the width D 2 identical (or littler) of gap H1 and opening 51,52 and 61 than it.Simultaneously, under the too small situation of H1, be difficult to form and keep eddy current A.Therefore, preferably, gap H1 is 0.5 times of width D 2 of opening 51,52 and 61.And when the path that forms corresponding to injection stream B and eddy current A, it is useful forming separator 100 corresponding to opening 51,52 and 61 ground.
For separator 100, opening 51,52 and 61 orientation also are very important for scattering cold air equably.Be explained to Fig. 6 B below with reference to Fig. 5 A.
Fig. 5 A and Fig. 5 B are the schematic views according to the cold air supply arrangement of the first embodiment of the present invention.Fig. 6 A and Fig. 6 B are the schematic views according to the improved cold air supply arrangement of the first embodiment of the present invention.To Fig. 6 B this cold air supply arrangement is described below with reference to Fig. 5 A, will carries out to Fig. 3 contrast with Fig. 1 to the explanation of Fig. 6 B Fig. 5 A.
At first, shown in Fig. 5 A and Fig. 5 B, the cold air supply arrangement has and is used for some openings that the generation cold air is discharged along different directions.More specifically, described opening is made up of first inlet, 11 and second inlet 112, and this first inlet is arranged at the roof of refrigerating chamber 30 and refrigerating chamber 40, and second inlet then is arranged at the sidewall of refrigerating chamber 30 and refrigerating chamber 40.
At this moment, first inlet 111 is discharged cold air to the bottom of refrigerating chamber 30 and refrigerating chamber 40.And second inlet 112 is discharged cold air to the top of opposing sidewalls.Therefore, the cold air of vibration is just discharged from the different piece of refrigerating chamber 30 and refrigerating chamber 40 by first inlet, 111 and second inlet 112.That is to say that the approximate range of discharging cold air broadens, so that advantageously cold air is spread in refrigerating chamber 30 and the refrigerating chamber 40 equably.For obtaining identical effect, first and second inlets 11 and 112 can be located shown in Fig. 5 B.Especially, first inlet 111 is discharged the cold air edge perpendicular to the direction of the cold airs of discharging from second inlet 112.
Owing to the interference of having strengthened cold air and mixed, thereby the turbulence intensity of cold air increases.Like this, the cold air of vibration just spreads in refrigerating chamber 30 and the refrigerating chamber 40 equably.Simultaneously, it is exactly possible obtaining the even temperature distribution.And the cold air supply arrangement has the cold air that is used for refrigerating chamber 30 and refrigerating chamber 40 and is discharged to extraneous outlet 120.Outlet 120 is arranged on the downside of refrigerating chamber 30 and refrigerating chamber 40, so that directly be not discharged to the external world from 111 and 112 cold airs of discharging that enter the mouth.Preferably, outlet 120 is arranged on the lower wall of refrigerating chamber 30 and refrigerating chamber 40, so that discharge cold air rapidly.
About refrigerating chamber 30, Fig. 1 supplies with the 3rd opening 61 that partly only has corresponding to second inlet 112 to illustrated in fig. 3 second.Referring to figs. 1 to Fig. 3, supply with first and second openings 51 and 52 that partly have corresponding to first and second inlets 111 and 112 about refrigerating chamber 40, the first.Like this, in the refrigerator of Fig. 3, preferably, supply with the other opening that partly has corresponding to first inlet 111 corresponding to second of refrigerating chamber 30 at Fig. 1.And in refrigerating chamber 30, outlet 120 is corresponding to the 4th opening 62.In refrigerating chamber 40, outlet 120 is corresponding to second intermediate openings 22.
Preferably, as shown in Figure 6A, the cold air supply arrangement also comprises third and fourth inlet 113 and 114, and wherein third and fourth inlet 113 and 114 is as opening.In this case, the 3rd inlet 113 is arranged at the bottom of the sidewall of refrigerating chamber 30 and refrigerating chamber 40, the below of second inlet 112.Like this, the 3rd inlet 113 is just discharged cold air to the bottom of opposing sidewalls.The 4th inlet 114 is arranged on the diapire of refrigerating chamber 30 and refrigerating chamber 40, so that cold air is discharged to the top of refrigerating chamber 30 and refrigerating chamber 40.
The 3rd inlet 113 makes it with vertical from the cold airs of the 4th inlet 114 discharges to discharge cold air with first and second inlets, 111 and 113 identical modes.By the third and fourth additional inlet 113 and 114, the approximate range of discharging cold air broadens, so that the turbulence intensity of cold air increases.And third and fourth inlet 113 and 114 produces big turbulent flow at refrigerating chamber 30 and refrigerating chamber 40 centers, and also produces identical turbulent flow in the upper and lower of refrigerating chamber 30 and refrigerating chamber 40.Therefore, the cold air of vibration spreads in refrigerating chamber 30 and the refrigerating chamber 40 equably.
Have under the condition of same effect, third and fourth inlet 113 and 114 can be provided with shown in Fig. 6 B.For the refrigerator of Fig. 1 to Fig. 3, first supplies with part and second supplies with the opening 51 and 61 that partly has respectively corresponding to the 3rd inlet 113.Therefore, preferably, first supplies with part and second supplies with the additional opening that partly has corresponding to the 4th inlet 114.And preferably, outlet 120 is arranged in the sidewall of refrigerating chamber 30 and refrigerating chamber 40 in the heart, rather than directly cold air 111,112,113 and 114 is discharged to the external world from entering the mouth.
Finally, because described opening is provided with to Fig. 6 B shown in as Fig. 5 A, thereby the cold air of being discharged produces the secondary turbulent flow in refrigerating chamber 30 and refrigerating chamber 40, thus the more uniformly dispersing of realization cold air.
Simultaneously because evaporimeter 71 broads, thereby from the cold air that the 4th opening 62 is discharged focused on evaporimeter 71 in the heart.Therefore, the heat exchanger effectiveness of evaporimeter 71 is lowered.And, not producing heat exchange in the left and right sides of evaporimeter 71, this makes in the left and right sides of evaporimeter 71 may frosting, thereby has reduced heat exchanger effectiveness.Therefore, to shown in Fig. 9 B, separator 100 is arranged in the 4th opening 62 as Fig. 7, is used for the cold air of circulation in refrigerating chamber 30 and refrigerating chamber 40 is discharged to evaporimeter 71.
Separator 100 shown in Figure 8 have with reference to the identical characteristic of the separator 100 of the figure 4 described first embodiment of the present invention.That is to say that separator 100 was separated at least two paths with cold air before cold air is discharged, thereby had reduced the speed of cold air.By separating cold air, it is possible forming at least two eddy current A between separator 100 and opening 62.And two injection stream B are formed by this path, and wherein these two injection stream B collide mutually to strengthen eddy current A.Therefore, the cold air that is vibrated is spread in the whole evaporimeter 71 equably.
And opening 62 is arranged to be adjacent to the intersection point that intersects with these two injection stream B, so that prevent to be subjected to the cold air of disturbance to disappear.For the same reason, the width D 2 identical (or littler) of the gap H1 between separator 100 and the opening 62 and opening 62 than it.Preferably, gap H1 is 0.5 times of width D 2 of opening 62.For forming eddy current A and injection stream B, the width of separator 100 is identical with the width D 2 of opening 62.
For the cold air with vibration directs into evaporimeter 71 smoothly, preferably, shown in Fig. 9 A and Fig. 9 B, second supplies with part can comprise additional subsidiary conduit 80.This subsidiary conduit 80 is connected with the 4th opening 80, and is adjacent to evaporimeter 71 extensions.And subsidiary conduit 80 comprises the assist openings 81 of its orientation towards evaporimeter 71, and separator 100 then is adjacent to this assist openings 81 and is provided with.Like this, along with cold air process refrigerating chamber 30 and refrigerating chamber 40, cold air just is separated device 100 vibrations and directly is discharged to evaporimeter 71.As a result, cold air is dispersed in the whole evaporimeter 71 equably.
In above-mentioned first and second embodiment of the present invention, be possible by improving the efficient that improves separator 100.Below with reference to Figure 10 A and Figure 12 B this is elaborated.
At first, shown in Figure 10 A, preferably, first and second subsidiary conduits 50,60,80 expand partly in the part that is adjacent to separator 100.That is to say that dilation 50a, 60a, 80a have increased the circumferential space that is adjacent to separator 100 basically.Therefore, separator 100 has reduced the loss on flow resistance, and separates cold air simultaneously.
Preferably, the width D 3 of dilation 50a, 60a and 80a is 2 to 2.5 times of width D 0 of pipeline 50,60 and 80.The height H 2 of dilation 50a, 60a and 80a is 1 to 1.2 times of width D 0 of pipeline 50,60 and 80.And, as Fig. 4 and Fig. 8 illustrated be that the width D of separator 100 equals the width D 0 of (or less than) pipeline 50,60 and 80, and the width D 2 of first to the 4th opening and assist openings 51,52,61,62 and 81.And gap H1 equals the width D 2 of (or less than) opening 51,52,61,62 and 81.Preferably, the gap of H1 is 0.5 times of width D 2 of opening 51,52,61,62 and 81.
If pipeline 50,60 and 80 promptly and significantly extends, cold air just temporarily has big resistance and greater loss so.Therefore, shown in Figure 10 B, dilation 50a, 60a and 80a have the structure that pipeline 50,60 and 80 is expanded gradually.That is to say that the sidewall of dilation 50a, 60a and 80a and pipeline 50,60 become predetermined angular ground to tilt with 80 sidewall.Like this, dilation 50a, 60a and 80a have just reduced the energy loss that is produced by flow resistance widely.
Under the situation that separator 100 is formed by flat member, the flow resistance that cold air is subjected to is bigger, thereby produces loss (that is energy loss) in making the air process of flowing.As mentioned above, the resistance coefficient of flat member is 2.0.Therefore, need to select to have the stream separator 100 of less resistance coefficient, reduce flow velocity under the situation with the separation that realizes path and the loss in reducing cold air.
At first, shown in Figure 11 A, separator 100 can form with curved shape.And separator 100 is outstanding with respect to the flow direction of cold air.In this case, the resistance coefficient of separator 100 is about 1.40.And shown in Figure 11 B, separator 100 can form with the pott's curvature shape, and wherein separator 100 can be outstanding with respect to the flow direction of cold air.Separator 100 has about 1.20 resistance coefficient.
