And, vegetable compartment 6 is carried out the cooled cold air bottom that flows into cooler receiving room 8 via vegetable compartment return-air mouth 6d (with reference to Fig. 4) as shown in Figure 4.Compare with the air quantity of the air quantity that in cryogenic temperature band chamber, circulates, circulation in refrigerating chamber 2, few from the air quantity of vegetable compartment return-air mouth 6d.Therefore, less for the influence of the flow field of the state of the cold air flow in the expression cooler receiving room 8 (below be called " flow field "), therefore omit explanation here.
Be not limited to the structure of the refrigerator 1 of this embodiment; In the refrigerator of the cold air forced circulation mode of cooling off through shared cooler 7 pairs of refrigerated storage temperature bands chamber and cryogenic temperature band chamber, the position of the inflow cooler receiving room 8 of each cold air that refluxes, to differences such as the inflow direction (angle) of cooler receiving room 8, air quantity.Therefore; For from the backflow cold air of cryogenic temperature band chamber with from for the formed above-mentioned field of flow of the backflow cold air of refrigerated storage temperature band chamber, in the situation of cooling refrigeration temperature band chamber only, only cool off the situation of cryogenic temperature band chamber, generally be different between the situation of cooling refrigeration temperature band chamber and cryogenic temperature band chamber simultaneously.
Then, to the Defrost method of refrigerator 1, describe with reference to Fig. 5 and Fig. 6.Fig. 5 is the figure of explanation defrosting mode.Time diagram when Fig. 6 is 4 times defrostings of defrosting mode.
And in following explanation, the state that compressor 24 is being worked is called " compressor ON ", compressor 24 is in the state that stops is called " compressor OFF ".In addition, the state that pressure fan in the case 9 is being worked is called " pressure fan ON in the case ", pressure fan in the case 9 is in the state that stops is called " pressure fan OFF in the case ".In addition, will be called " Defrost heater ON ", the state of Defrost heater 22 not being switched on will be called " Defrost heater OFF " the state of Defrost heater 22 energisings.In addition; With refrigerating chamber cooling air flap 20 for open mode, can be called " the refrigerating chamber cooling air flap is opened " to the state of refrigerated storage temperature band chamber air-supply, refrigerating chamber cooling air flap 20 is called " the refrigerating chamber cooling air flap closes " for closed condition, the state that interdicted to the air-supply of refrigerated storage temperature band chamber.In addition; With refrigerating chamber cooling air flap 50 for open mode, can be called " the refrigerating chamber cooling air flap is opened " to the state of cryogenic temperature band chamber air-supply, refrigerating chamber cooling air flap 50 is called " the refrigerating chamber cooling air flap closes " for closed condition, the state that interdicted to the air-supply of cryogenic temperature band chamber.
In addition; Pattern as the common cooling running of refrigerator 1; Have a plurality of cooling operation modes, state that will " pressure fan ON, refrigerating chamber cooling air flap leave in the compressor ON, case, the refrigerating chamber cooling air flap closes, Defrost heater OFF " is called " refrigerating chamber cooling running " pattern.
In addition, state that will " pressure fan ON, refrigerating chamber cooling air flap close in the compressor ON, case, the refrigerating chamber cooling air flap is opened, Defrost heater OFF " is called " refrigerating chamber cooling running " pattern.
In addition, state that will " pressure fan ON, refrigerating chamber cooling air flap leave in the compressor ON, case, the refrigerating chamber cooling air flap is opened, Defrost heater OFF " is called " refrigerating chamber and refrigerating chamber cool off running simultaneously " pattern.
Here; Usually the cooling running is meant following running: the temperature that is detected based on refrigerator temperature sensor, freezer temperature sensor and outer temperature degree sensor; Control through the open and-shut mode of pressure fan 9, case control of pressure fan outward (ON/OFF control or rotary speed are controlled) and refrigerating chamber cooling air flap 20, refrigerating chamber cooling air flap 50 in compressor 24, the case; Each chamber (is for example maintained predetermined temperature; Refrigerating chamber is about 3 ℃, and vegetable compartment is about 5 ℃, and refrigerating chamber is about-18 ℃).
And, in the explanation of following Defrost method,, omit about the explanation of vegetable compartment 6 with the part of vegetable compartment 6 as refrigerating chamber 2.
As shown in Figure 5, the refrigerator 1 of this embodiment possesses defrosting mode 1～6 these the six kinds of patterns as pattern under the defrosting running.Shown in the below of the table of Fig. 5; The defrosting mode 1 that in these defrosting modes, carries out " the defrosting with pressure fan in the case " of " pressure fan ON, refrigerating chamber cooling air flap leave in the compressor OFF, case, the refrigerating chamber cooling air flap closes, Defrost heater OFF " is called " first Defrost method ".
In addition, the defrosting mode 3 that carries out " the defrosting with pressure fan+Defrost heater in the case " of " pressure fan ON, refrigerating chamber cooling air flap leave in the compressor OFF, case, the refrigerating chamber cooling air flap closes, Defrost heater ON " is called " second Defrost method ".
In addition, the defrosting mode 6 that carries out " the defrosting with Defrost heater " of " pressure fan OFF, refrigerating chamber cooling air flap close in the compressor OFF, case, the refrigerating chamber cooling air flap closes, Defrost heater ON " is called " the 3rd Defrost method " put down in writing in the technical scheme.
In addition, " the 4th Defrost method " is the method that one or more of above-mentioned first Defrost method, second Defrost method and the 3rd Defrost method is made up the running of implementing to defrost.
And, after defrosting mode 2 turns round for defrosting with defrosting mode 1 (first Defrost method), the pattern that then defrosts and turn round with defrosting mode 3 (second Defrost method).
In addition, defrosting mode 4 is followed the pattern that defrosts and turn round with defrosting mode 3 (second Defrost method), defrosting mode 6 (the 3rd Defrost method) for the running back of defrosting with defrosting mode 1 (first Defrost method).
In addition, defrosting mode 5 is followed the pattern that defrosts and turn round with defrosting mode 6 (the 3rd Defrost method) for the running back of defrosting with defrosting mode 3 (second Defrost method).
Like this, the pattern of the running of the defrosting in the refrigerator 1 of this embodiment is used as defrosting mode with the whole of first to the 3rd Defrost method or part combination.
Shown in " defrosting precondition " hurdle of the table of Fig. 5, cooling operation mode, freezer temperature or the temperature of refrigerating chamber of the refrigerator 1 before the defrosting running beginning that defrosting mode 1～6 is suitable for are different to the condition of temperature.In addition, should be readily appreciated that, record the combination of first～the 3rd Defrost method in " combination of Defrost method " hurdle of the table of Fig. 5 in order to make each defrosting mode.And, defrosting mode 1～6 has been shown in " defrosting finishes decision condition " hurdle of the table of Fig. 5 under the condition of the defrosting end judge temperature of what kind of freezer temperature, temperature of refrigerating chamber, chiller temperature, has finished each defrosting mode.And as an example, even if under situation about judging through freezer temperature, the Temperature numerical that is suitable in each pattern is different.And the condition of the chiller temperature shown in " defrosting finishes decision condition " hurdle of the table of Fig. 5 finishes judge temperature corresponding to defrosting.
Usually the cooling running has three kinds of above-mentioned cooling operation modes.Therefore; Under the situation that continues cooling running usually; Except continuing " refrigerating chamber cooling running " pattern, also switch to " refrigerating chamber cooling running " other two kinds cooling operation modes (" refrigerating chamber cooling running " pattern, " refrigerating chamber and refrigerating chamber cool off running simultaneously " pattern) beyond the pattern sometimes based on temperature of refrigerating chamber, freezer temperature.
For example; Taken place the user with temperature higher food put under the situation of refrigerating chamber 2 grades; Switch to " refrigerating chamber cooling running " pattern from " refrigerating chamber cooling running " pattern, after refrigerating chamber 2 is cooled to predetermined temperature rapidly, transfer to " refrigerating chamber cooling running " pattern again.
Then, describe to the action effect of the defrosting mode 4 of Fig. 5 with reference to Fig. 6.And control shown in Figure 6 is following.Just; Select defrosting mode 4; Divide into " refrigerating chamber cooling running " interval, with " first Defrost method " defrost running interval, with " second Defrost method " defrost the interval TB of running, with " the 3rd Defrost method " defrost the interval TC of running, defrosting running finish after through interval TD, TE, " cooling running usually " interval, show the ON/OFF state of pressure fan 9 in the open mode/closed condition, case of ON/OFF state, the refrigerating chamber cooling air flap 20 of pressure fan 9 in the passing of therebetween temperature of refrigerating chamber, freezer temperature and chiller temperature, the ON state (160W) of Defrost heater 22/ON state (80W)/OFF state, the case, the open mode/closed condition of refrigerating chamber cooling air flap 50, the ON state/OFF state of compressor 24.
As shown in Figure 6; Select under the situation of defrosting mode 4; Before the running that defrosts with defrosting mode 4;, implements temperature of refrigerating chamber refrigerating chamber cooling running before surpassing 5 ℃, after temperature of refrigerating chamber surpasses 5 ℃, with the running (" compressor OFF, the interior pressure fan ON of case, refrigerating chamber cooling air flap leave, the refrigerating chamber cooling air flap closes, Defrost heater OFF ") that defrosts of first Defrost method.
This is owing to pressure fan 9 in through case melts under the situation of frost to refrigerating chamber 2 air-supplies; The temperature of refrigerating chamber 2 as far as possible when the high temperature easily with carry out heat exchange attached to the frost on the cooler 7; Therefore improve the temperature of refrigerating chamber 2 in advance, make energy-saving effect promote thus.In addition; Owing to cool off running owing to implement refrigerating chamber outside from case between the entering waiting temperature rising stage of heat at refrigerating chamber 2; Therefore in the time of can before defrosting, making defrosting since from the entering of heat case outside and easily the refrigerating chamber that rises of temperature fully cool off, also have the effect of the possibility that when defrosting, reduces the such undesirable condition of frozen food thawing.
Phase I implements to defrost under the situation of running with first Defrost method in as defrosting mode 4; Shown in interval TA among Fig. 6; Temperature of refrigerating chamber is owing to cold and hot being cooled of frost, and on the other hand, chiller temperature (white temperature) is owing to the thermic load of refrigerating chamber rises; Little by little, the difference of refrigerating chamber and chiller temperature reduces.After the temperature difference of temperature of refrigerating chamber and chiller temperature reduces, owing to be difficult to carry out heat exchange, therefore still proceed to defrost under the situation of running with first Defrost method, defrosting time can prolong.On the other hand, as shown in Figure 6, during defrosting, freezer temperature continues to rise.
Therefore; If defrosting time is long, the possibility that then exists frozen food to melt such undesirable condition is not hope situation about occurring; Therefore do not make the defrosting time prolongation for (satisfy (temperature of refrigerating chamber-chiller temperature)≤2 ℃ situation) under the situation about reducing in the temperature difference that is judged as temperature of refrigerating chamber and chiller temperature; Through making Defrost heater is ON, to return air heating from refrigerating chamber 2, thus defrosting easily.State that should " pressure fan ON, refrigerating chamber cooling air flap leave in the compressor OFF, case, the refrigerating chamber cooling air flap closes, Defrost heater ON " among the interval TB of Fig. 6 with second Defrost method defrost running, the i.e. state of enforcement " defrosting " with pressure fan+Defrost heater in the case.The power of Defrost heater 22 is 80W in second Defrost method, if the residual state that frost is arranged in the cooler 7, then this power makes about 0～4 ℃ the temperature that becomes the cooling that can carry out refrigerating chamber 2 through the air behind the cooler 7.
And the temperature of the cooler 7 of this moment self is owing to below the evaporation that is present in aqueous cold coal in the cooler 7 becomes approximately-10 ℃.In other words, interval TB is the temperature that comprises attached to frost on the fin surface that constitutes cooler 7 among above-mentioned Fig. 6.In addition, under the application's the situation, the end of interval TB is carried out through previous chiller temperature sensor 35.
The rotary speed of pressure fan 9 is about 1600min in case when in addition, cooling is turned round usually
-1, defrosting between on-stream period with second Defrost method among the interval TB is about 1400min
-1Like this when running of defrosting with second Defrost method with case in the rotary speed of pressure fan 9 rotary speed during from common cooling running change to some extent, be in order to be adjusted to about 0～4 ℃ air themperature of the cooling that can obtain carrying out refrigerating chamber 2.
Like this; Since the refrigerator 1 of this embodiment be adjusted to about 0～4 ℃ air themperature of the cooling that can obtain carrying out refrigerating chamber 2 with the running that defrosts of second Defrost method; Can solve disclosed in patent documentation 2, the patent documentation 3 is that purpose is implemented " because the cold and hot cooling that can not be used in refrigerating chamber again of available frost; therefore correspondingly energy-efficient performance descends " this problem points of producing under " pressure fan ON, refrigerating chamber cooling air flap leave in compressor OFF, the case, the refrigerating chamber cooling air flap closes, Defrost heater ON " situation with the humidification, has improved energy-saving efficiency.
If the power output of Defrost heater 22 is superfluous in the defrosting that " defrosts with pressure fan+Defrost heater in the case " running; Then be higher than the temperature that in refrigerating chamber 2, should keep through the air themperature behind the cooler; Can heat refrigerating chamber 2, therefore unsuitable.In addition, the purpose owing to the defrosting running of carrying out with second Defrost method is if therefore the power output of Defrost heater 22 is too small, then can not reach this purpose through shortening the rising that defrosting time comes the freezing-inhibiting room temperature.Therefore, the power output of Defrost heater 22 must be suitable in second Defrost method.Effect as second Defrost method; Except the freezing-inhibiting room temperature rises; Though make Defrost heater 22 be ON; But in to refrigerating chamber 2 coolings, make frost melt (using the thermic load of refrigerating chamber 2 that frost is melted), the energy input amount from the outside that therefore is used to defrost has reduced to be equivalent to utilize the part of the thermic load of refrigerating chamber 2, can access energy-saving effect.And, owing to make return air forced convertion in cooler 7 from refrigerator through air-supply, so the heat conduction efficiency between air and the frost is good, also has because frost melts the energy-saving effect that brings easily.
Like this, through in the running back combination of defrosting with first Defrost method with the running that defrosts of second Defrost method, energy-saving effect when turning round can obtain defrosting when shortening defrosting time.
Then; Time point below temperature of refrigerating chamber reaches chiller temperature becomes " pressure fan OFF, refrigerating chamber cooling air flap close in the case "; The power output of Defrost heater 22 is changed into 160W from 80W; Therefore at the interval TC of Fig. 6, implement promptly " to defrost " with Defrost heater with the running that defrosts of the 3rd Defrost method.Reach chiller temperature when following at temperature of refrigerating chamber; The cold and hot ability that does not have refrigerated compartment 2 that cooler 7 is held if continue air-supply again, then can heat refrigerating chamber 2; Therefore through out-of-blast and carry out " defrosting " with Defrost heater; Prevent refrigerating chamber 2 is heated, and, make the not residual frost that does not melt in the cooler 7.
The defrosting mode 4 necessary feasible not residual frosts that do not melt; As stated; Under " pressure fan ON in the case " state, only defrost under the situation of running, can produce the position that frost is difficult to melt, have the situation that produces the residual frost that does not melt with first Defrost method or second Defrost method.So, after under " the pressure fan ON state in the case " of first Defrost method and second Defrost method, defrosting, shown in the interval TC of Fig. 6, implement " defrosting " the feasible not residual frost that does not melt with Defrost heater.
And, in this embodiment, defrosting when running with the 3rd Defrost method, the power of Defrost heater 22 is risen to 160W from 80W.Thus, can shorten with the defrost interval TC of running of the 3rd Defrost method, the temperature of refrigerating chamber that can will be therebetween and the rising inhibition of freezer temperature are for very little.
In addition, when defrosting running with the 3rd Defrost method, compare with the defrosting under the ventilation state, poor based on air in the cooler receiving room 8 with the heat conduction efficiency of the free convection of frost, belong to the low Defrost method of energy-saving efficiency.But; Implement with the running that defrosts of the 3rd Defrost method owing to be higher than such we can say of the temperature of refrigerating chamber that the remains above-zero temperatures state that nearly all frost melts from chiller temperature, therefore less based on the defrost influence for the energy-efficient performance reduction of running of Defrost method.
Like this, in defrosting mode 4, through making up the running that defrosts of first to the 3rd Defrost method, can carry out flexibly and have energy-saving effect, effectively defrosting really, can also seek to shorten defrosting time, the freezer temperature that suppresses therebetween rises.
Then; When chiller temperature surpasses 8 ℃; Make Defrost heater 22 be OFF; The defrosting running that end is carried out with defrosting mode 4, shown in the interval TD of Fig. 6, wait is 5 minutes under the state of " pressure fan OFF, refrigerating chamber cooling air flap close compressor OFF, case in, the refrigerating chamber cooling air flap closes, Defrost heater OFF ".Through the interval TD of this process; Can guarantee that defrost water drops onto the time of aqueduct 23 from cooler 7, upper lid 53 (with reference to Fig. 5), cause once more an icing part to stop up such state of affairs cooler receiving room 8 thereby be difficult to produce owing in the drippage way, restart common cooling running.
In addition; Finish when surpassing 8 ℃ with the running that defrosts of the 3rd Defrost method at chiller temperature; Be set to compare and finish the temperature of judge temperature (chiller temperature＞0.5 ℃) higher temperature shown in Figure 6 not comprising, therefore can defrost basically fully with the defrost defrosting of other defrosting mode of running of the 3rd Defrost method.
After past 5 minutes through interval TD; Enter into interval TE; The TE in this interval at first only makes compressor 24 for ON (" pressure fan OFF, Defrost heater OFF, refrigerating chamber cooling air flap close in compressor ON, the case, the refrigerating chamber cooling air flap closes "), waits for 2 minutes; Then, restart common cooling running.This stand-by period of 2 minutes is that the air for cooler 7 that is difficult to be created in the time point increase in temperature that the defrosting running carried out with defrosting mode 4 finishes and periphery thereof directly is sent to each chamber in the case and causes problem that each chamber in the case is heated, is provided with in order before restarting common cooling running, to cool off in cooler receiving room 8.
Therefore the present invention can access and suppress to control the refrigerator that improves energy-saving efficiency through the temperature of carrying out refrigerating chamber when cold air path depth size enlarges owing to having the as above structure of explanation.In addition, can access in food and guarantee energy-efficient performance when maintaining predetermined temperature range, can keep the refrigerator of food storage temperature refrigerator.
