(embodiment 1)
Fig. 1 is the skiagraph of the freezer of embodiments of the present invention 1.Fig. 2 is the front elevation of the state of the door of the freezer opening embodiments of the present invention 1.Fig. 3 is the sectional drawing returned near air channel of the freezer of embodiments of the present invention 1.
In Fig. 1 to Fig. 3, the freezer main body 11 be made up of thermal wall has refrigerating chamber 12 on top, has refrigerating chamber 13 in bottom.In addition, freezer main body 11 has the refrigerant loop be made up of compressor 1, condenser (not shown), decompressor (not shown), cooler 4 in inside.
Refrigerating chamber 13 has the cooling chamber 14 at inside storage cooler 4.Cooling chamber 14 is separated with cooled device cover 15 in refrigerating chamber 13 storehouse.
Have above cooler 4: make the cold air (cooling air) generated in cooler 4 optionally to cooling fan 7, refrigerating chamber air-supply air door 9a and refrigerating chamber air-supply air door 8a that refrigerating chamber 12 and refrigerating chamber 13 circulate.
Refrigerating chamber air-supply air door 9a with discharge air channel 16 by refrigerating chamber in refrigerating chamber 12 storehouse and be communicated with, to blow air door 9a by opening refrigerating chamber, refrigerating chamber 12 is communicated with cooling chamber 14.That is, refrigerating chamber air-supply air door 9a optionally inaccessible or open refrigerating chamber discharge air channel 16.Refrigerating chamber is discharged air channel 16 and the cooling air produced by cooling fan 7 is guided to refrigerating chamber 12.
Refrigerating chamber air-supply air door 8a with discharge air channel 17 by refrigerating chamber in refrigerating chamber 13 storehouse and be communicated with, to blow air door 8a by opening refrigerating chamber, refrigerating chamber 13 is communicated with cooling chamber 14.That is, refrigerating chamber air-supply air door 8a optionally inaccessible or open refrigerating chamber discharge air channel 17.Refrigerating chamber is discharged air channel 17 and the cooling air produced by cooling fan 7 is guided to refrigerating chamber 13.In the running of cooling fan 7, open refrigerating chamber air-supply air door 9a and refrigerating chamber air-supply air door 8a time different.
At the back side of ratio cooler 4 part on the lower of cooling chamber 14, there is refrigerating chamber suction inlet 18, there is above refrigerating chamber suction inlet 19, return refrigerating chamber to be returned air channel 20 and refrigerating chamber the mode opening that air channel 21 is communicated with respectively.That is, refrigerating chamber suction inlet 19 is arranged on the face that depth direction is relative with refrigerating chamber suction inlet 18.In addition, refrigerating chamber returns to air channel 20 and is arranged between cooling chamber 14 and freezer main body 11 with the width roughly the same with cooler 4 or its above width.Refrigerating chamber returns to air channel 20 and the cold air cooling refrigerating chamber 12 is guided to cooling chamber 14 again.Refrigerating chamber returns to air channel 21 and is arranged at cooler cover 15 bottom.Refrigerating chamber returns to air channel 21 and the cold air cooling refrigerating chamber 13 is guided to cooling chamber 14 again.
In the below of cooler 4, the heating parts 22 such as the pharoid of the frost thawing be attached to because of cooling running on cooler 4 are arranged between the top and bottom of the opening of refrigerating chamber suction inlet 18.And, the water dish 23 for being discharged to the outside by the water produced when melting frost and drainpipe 24 is provided with in the below of heating part 22.
In addition, there is in cooler 4 side of the lower end of cooler cover 15 the water-dropper 15a of the convex protruded downwards.
In the bottom of cooler cover 15, there is anti-inflow wall 25.Anti-inflow wall 25 is formed as the shape of rectangular tabular, and width is at least wide than the width of refrigerating chamber suction inlet 18.In addition, anti-inflow wall 25 has the fitting portion 25a chimeric with the wall of (front) before water dish 23 in bottom.Thereby, it is possible to eliminate the gap of anti-inflow wall 25 and water dish 23, and the deviation of the position of anti-inflow wall 25 can be eliminated.
In addition, anti-inflow wall 25 tilts for upper end is than the rear side of lower end closer to freezer main body 11, and the perspective plane be configured at than the vertical below of cooler 4 is closer to the position of front face side.Anti-inflow wall 25 is arranged between refrigerating chamber suction inlet 18 and refrigerating chamber suction inlet 19, prevents the cold air of discharging from refrigerating chamber suction inlet 18 from returning adverse current air channel 21 at refrigerating chamber and flowing into refrigerating chamber 13 from refrigerating chamber suction inlet 19.
Below, the action according to the freezer formed with upper type is described.
When freezer operates, storehouse temperature raises, and the temperature of refrigerating chamber 13 exceedes fiducial temperature, and when needing cooling refrigerating chamber 13, compressor 1 stops luck rotary compressor 1.On the other hand, remain in operation when compressor 1 operates compressor 1.Then, running cooling fan 7, and open refrigerating chamber air-supply air door 8a, closing cold room air-supply air door 9a.
Thus, the cold air generated in cooler 4 flows through refrigerating chamber discharge air channel 17 from refrigerating chamber air-supply air door 8a and flows in refrigerating chamber 13, thus in cooling refrigerating chamber 13.
Now, cool the Quilt with air conditioning after refrigerating chamber 13 to suck refrigerating chamber successively and return air channel 21, refrigerating chamber suction inlet 19, again cooled in cooler 4, discharge air channel 17 by cooling fan 7 discharge in refrigerating chamber 13 storehouse from refrigerating chamber air-supply air door 8a, refrigerating chamber.
On the other hand, exceed fiducial temperature in the temperature of refrigerating chamber 12, when needing refrigerated compartment 12, running cooling fan 7, and open refrigerating chamber air-supply air door 9a, close refrigerating chamber air-supply air door 8a.
Thus, the cold air generated in cooler 4 flows through refrigerating chamber discharge air channel 16 from refrigerating chamber air-supply air door 9a and flows in refrigerating chamber 12, thus in refrigerated compartment 12.
Now, cool the cold air after refrigerating chamber 12 and be inhaled into refrigerating chamber successively and return air channel 20, refrigerating chamber suction inlet 18, the anti-inflow wall 25 of Quilt with air conditioning of discharging from refrigerating chamber suction inlet 18 is changed into towards cooler 4 side.Then, cold air is again cooled in cooler 4, is discharged air channel 16 and discharges in refrigerating chamber 12 storehouse afterwards by cooling fan 7 from refrigerating chamber air-supply air door 9a, refrigerating chamber.
Herein, when not anti-inflow wall 25, cross the wall before water dish 23 from the cold air of refrigerating chamber suction inlet 18 suction, return adverse current in air channel 21 at refrigerating chamber and flow in refrigerating chamber 13 from refrigerating chamber suction inlet 19.Now, from the cold air that refrigerating chamber suction inlet 18 flows into, owing to cooling refrigerating chamber 12 so higher than the temperature in refrigerating chamber 13, the temperature of refrigerating chamber 13 raises.
On the other hand, when there being anti-inflow wall 25, the cold air sucked from refrigerating chamber suction inlet 18 flows from water dish 23 along anti-inflow wall 25.Thus, the direction of the flowing of cold air becomes towards cooler 4 side, therefore can not flow to the direction of refrigerating chamber suction inlet 19.
Therefore, even if do not arrange the such air door of conventional example at refrigerating chamber suction inlet 19, in the process of refrigerated compartment 12, refrigerating chamber 13 also can not be cooled the cold gas after refrigerating chamber 12.Therefore, it is possible to raise with the temperature of cheap structure reliably freezing-inhibiting room 13, and the freezer that cooling performance is high can be provided.
In addition, refrigerating chamber returns to air channel 20 and is arranged between the thermal wall at the back side of cooling chamber 14 and freezer main body 11 with the width roughly the same with cooler 4 or its above width.Therefore, it is possible to reduce the temperature difference in the extraneous air and freezer main body 11 of thermal wall.Consequently, heat is mobile to be reduced, and effect of heat insulation strengthens, but flowing through cold air temperature compared with existing structure that freezer returns in air channel 20 uprises.
And, when refrigerated compartment 12, adopt structure cold air only being circulated in refrigerating chamber 12 by closing refrigerating chamber air-supply air door 8a.Thus, with do not have refrigerating chamber blow the situation of air door 8a, refrigerating chamber 12 cooling procedure in do not close refrigerating chamber blow air door 8a situation compared with, the temperature of cooler 4 can be improved.Consequently, the cooling cycle efficiency in refrigerated compartment 12 process improves, but the temperature flowing through the cold air that refrigerating chamber returns in air channel 20 raises further.
In such an embodiment, also can reliably prevent cold air from leaking to refrigerating chamber 13.
Therefore, also the temperature of freezing-inhibiting room 13 can raise in the freezer that effect of heat insulation is higher, and the freezer that cooling performance is high can be provided.
In addition, in the freezer of present embodiment, refrigerating chamber suction inlet 18 and refrigerating chamber suction inlet 19 are more leaning on vertical below one side opening than cooler 4.Thus, the fin not reducing cooler 4 hypomere just can prevent cold air from leaking to refrigerating chamber 13.
Therefore, it is possible to the temperature not reducing the freezing-inhibiting room 13, ability ground of cooler 4 raises, and the freezer that cooling performance is high can be provided.
In addition, anti-inflow wall 25 fixes with water dish 23 by fitting portion 25a.Therefore, it is possible to utilize water dish 23 and anti-inflow wall 25 that the cold air after cooling refrigerating chamber 12 is guided to cooler 4.Thereby, it is possible to water dish 23 is used as air channel, anti-inflow wall 25 can be reduced.In addition, owing to fixing anti-inflow wall 25 with the fitting portion 25a chimeric with water dish 23, so the deviation that can not produce because of part dimension and assembling and produce gap between water dish 23 and anti-inflow wall 25, the situation that cold air bleeds in refrigerating chamber 13 from gap.
Therefore, it is possible to cheaper structure, more reliably the temperature of freezing-inhibiting room 13 raises, and can provide the freezer that cooling performance is high.
In addition, anti-inflow wall 25 is made of one structure with cooler cover 15.Thereby, it is possible to minimizing number of components, therefore, it is possible to the anti-inflow wall 25 of cheaper price structure.
Therefore, it is possible to raise with the temperature of cheaper formation freezing-inhibiting room 13, and the freezer that cooling performance is high can be provided.
In addition, refrigerating chamber suction inlet 18 is from the position higher than heating part 22 to low position opening.Therefore, cool the cold air after refrigerating chamber 12 and be inhaled into from refrigerating chamber suction inlet 18, be attracted to cooler 4 from the position lower than heating part 22 from water dish 23 along anti-inflow wall 25, be directly inhaled into cooler 4 from the position higher than heating part 22.
On the other hand, when refrigerating chamber suction inlet 18 only at the position opening higher than heating part 22, when the cold air from refrigerating chamber suction inlet 18 is inhaled into cooler 4, due to its direction sharply change thus the pressure loss increase.
In addition, when refrigerating chamber suction inlet 18 only at the position opening lower than heating part 22, from refrigerating chamber suction inlet 18 suck cold air all flow to anti-inflow wall 25 from water dish 23, wind speed accelerates.Therefore, in order to prevent cold air from bleeding in refrigerating chamber 13, need to make anti-inflow wall 25 to cooler 4 lopsidedness further, compression losses increases.
In addition, when in order to reduce the pressure loss adopt the structure making heating part 22 away from refrigerating chamber suction inlet 18, in order to ensure safety, need to make heating part 22 have certain distance with the parts of surrounding.Therefore, cooling chamber 14 increases, and storehouse internal volume diminishes.
Therefore, as in the present embodiment, if refrigerating chamber suction inlet 18 is at the height opening from the position higher than heating part 22 to low position, then can not reduce storehouse internal volume, can the pressure loss in air channel be suppressed less thus the rising of the temperature of freezing-inhibiting room 13, the freezer that cooling performance is high can be provided.
In addition, because anti-inflow wall 25 is in beyond the perspective plane of vertical below of cooler 4, the defrost water therefore produced when carrying out the action of melting the frost be attached on cooler 4 can not spill in storehouse, shaft ice frozen room 13 along anti-inflow wall 25.
In addition, cooler cover 15 has water-dropper 15a.Thus, even if the water melted on cooler 4 surface flows through along cooler cover 15, also fall downwards at water-dropper 15a.Therefore, water can not spill in refrigerating chamber 13 along cooler cover 15.Now, in case the upper end flowing into wall 25 forms anti-inflow wall 25 than water-dropper 15a closer to the angle of the front face side of freezer main body 11.Thus, the water fallen from water-dropper 15a also can not along anti-inflow wall 25 to refrigerating chamber 13 internal leakage.
Therefore, it is possible to anti-sealing bleeds in refrigerating chamber 13 and the temperature of freezing-inhibiting room 13 raise, the freezer that cooling performance is high can be provided.
In addition, in the present embodiment, refrigerating chamber 13 is adopted to be configured in down, the structure that refrigerating chamber 12 is configured in, but if having the freezer of two temperature band, even then the structure of left and right configuration refrigerating chamber 13 and refrigerating chamber 12 also can obtain same effect.
In addition, in the present embodiment, the freezer with refrigerating chamber 13 and refrigerating chamber 12 two storerooms is illustrated, as long as there is the freezer of plural storeroom and there is with the back side freezer of suction inlet before cooling chamber 14, just can obtains same effect.
In addition, in the present embodiment, refrigeration system by using the refrigerant compression formula freeze cycle of compressor 1 to generate cold air is illustrated, but as long as generate the freeze cycle of cold air in cooler 4, in any refrigeration system, same effect can both be obtained.
