During the time, temperature Te1 of the vaporizer 11 that (moment TM1) detects is lower than the second temperature TA
Temperature information, it is judged that need to carry out adding defrosting operation, again drive defroster 13.Additionally,
The position of 0 expression temperature 0 DEG C shown in the longitudinal axis of Fig. 5, the first temperature TX is set in more than 0 DEG C.
If defrosting operation starts, then the basic defrosting operation of step S1 starts (moment TM0).
Then, judge in step s 2 to drive the persistent period whether to arrive the very first time (moment TM1),
When judging to arrive the very first time, advancing to Y-direction, basic defrosting operation stops (step S4).
Additionally, in step s 2, it is judged that when driving the persistent period not arrive the very first time, to N direction
Advance, it is judged that whether temperature Te of vaporizer 11 arrives the first temperature TX (step S3), sentences
During disconnected arrival the first temperature TX, advance to Y-direction, basic defrosting operation stopping (step S4)
And return the generally control (being equivalent to the CA11 of Fig. 5) of step S8.Do not arrive the first temperature TX
Time, advance to N direction and return step S2.
After basic defrosting operation stops (step S4), it is judged that the temperature of vaporizer 11 during moment TM1
Degree Te1 lower than the second temperature TA (step S5), during "Yes", advances to Y-direction,
At moment TM2 (after the second time) after the stipulated time, extend defrosting operation and start
(step S6) (is equivalent to the CA13 of Fig. 5).If additionally, be "No" in step s 5,
Then advance to N direction, do not implement to extend defrosting operation and return the usual of step S8 and control (phase
When in the CA12 of Fig. 5).
After the prolongation defrosting operation of execution step S6 starts, in step S6A, it is judged that vaporizer

But, in the case of CA13, in the moment TM1 that basic defrosting operation terminates, evaporation
Temperature Te1 of device 11 does not arrives defrosting end temp (the first temperature TX), does not arrives than it yet
Low design temperature (the second temperature TA).Above-mentioned example is equivalent to such as be attached to vaporizer 11
On the many situation of amount of frost.
In this case, control portion 24 is according to the evaporation after basic defrosting operation period H1
Temperature Te1 of device 11 is lower than the second temperature TA, judges to need by additional defrosting operating function FK2
Carry out extending defrosting operation.Further, after the stipulated time (after the second time SP1)
Moment TM2, again drive defroster 13 (ON be equivalent in figure shows) make prolongation
Defrosting operation starts.Extend defrosting operation extend defrosting operation during terminate through the 3rd time
Moment TM3 after H2 terminates.Certainly, even if in during above-mentioned prolongation defrosting operation, evaporation
The temperature of device 11 also makes prolongation defrosting operation stop when arriving the first temperature TX (defrosting end temp)
Only.
Extend defrosting operation period H2 to be set as than the basic time short for defrosting operation period H1.?
In present embodiment, basic defrosting operation period H1 (very first time) is 70 minutes, and prolongation removes
Frost operation period H2 (the 3rd time) is 6 minutes.By prolongation defrosting operation period H2 is set
Shortly fixed, it is possible to prevent the excessive temperature of vaporizer 11 to rise.Moreover it is preferred that user
During can suitably changing above-mentioned setting.
Preferably, above-mentioned second temperature TA is higher than the melting point of ice, and than the mesh of cold room 3
Mark design temperature (such as 5 DEG C) is low.That is, the second temperature TA can be about 0～3 DEG C.This
Outward, it is preferred that defrosting end temp (the first temperature TX) be 5 higher than the second temperature TA～
About 10 DEG C.
By making the second temperature TA higher than the melting point of ice, in ice melts (in latent heat heat exchange)
State under, the temperature of vaporizer 11 will not be arrived, it is possible to judge needs carry out extend defrosting
Operation such that it is able to reliably remove the frosting of residual.Additionally, by the target than cold room 3
Design temperature is low, it is possible to prevents the temperature arrival cold room more than 3 of vaporizer 11 from also carrying out prolongation and removes
Frost operation, thus prevent heat during defrosting operation from transmitting in cold room 3.
It addition, in the present embodiment, at the vaporizer 11 after basic defrosting operation period H1
Temperature Te1 lower than the second temperature TA time, it is judged that need carry out add defrosting operation, but also
Being not limited to this, such as, Te1 can be the time terminating to begin to pass through regulation from basic defrosting operation
After.In this case, at the end of basic defrosting operation, though driving because of defroster 13
Move noise when stopping and causing the detected value of temperature detector 15 to fluctuate, by using above-mentioned fluctuation
The detected value of the temperature detector 15 after recovery, it is possible to detect the temperature of vaporizer 11 more accurately.
Even if additionally, the driving of defroster 13 stops, but sometimes at certain period heater, there is heat,
It is possible to after consequent variations in temperature, detect the temperature of vaporizer 11.
＜ embodiment 2 ＞
Then, utilize the flow chart shown in Fig. 6 and the sequential chart shown in Fig. 7, the second behaviour will be related to
The embodiment making function illustrates as embodiment 2, and above-mentioned second operating function is according to arriving
The temperature information that the temperature of the very first time (moment TM1) finisher 11 declines, it is judged that need into
Row adds defrosting operation and again drives.Owing to being equivalent to the initial of operation sequence that substantially defrost
Operation is same as in Example 1 and eliminates explanation, and Fig. 6 only represents from step S5 to step S8
Add defrosting operation sequence.
In the present embodiment, after basic defrosting operation stops (step S4), moment TM1 is stored
Temperature Te1 (step S5A) of vaporizer 11.Then, step S5B is advanced to, to process
After stipulated time, i.e. temperature Te2 of moment TM2 after stopping period SP1 (the second time)
Compare with temperature Te1 of the vaporizer of the moment TM1 of storage in step S5A, it is judged that
Whether temperature declines (Te1 >=Te2).When being "Yes" in above-mentioned steps S5B, to Y-direction
Advance, extend defrosting operation at moment TM2 and start (step S6) (suitable with the CA23 of Fig. 7).
If additionally, be "No" in step S5B, then advance to N direction, do not implement to extend defrosting
Operation, return step S8 generally controls (suitable with the CA22 of Fig. 7).
If such as stopping period SP1 (the second time) is 5 minutes, then confirm through above-mentioned 5
Temperature Te2 after minute is lower than temperature Te1, thus judges whether that needs carry out extending defrosting
Operation.That is, if it is confirmed that temperature Te2 after 5 minutes is lower than temperature Te1 (with Fig. 7's
CA23 is suitable), then judge that needs carry out extending defrosting operation, if it is confirmed that after 5 minutes
Temperature Te2 higher than temperature Te1 (suitable with the CA22 of Fig. 7), then judge to be made without prolonging
Long defrosting operation.
According to above-mentioned composition, after basic defrosting operation terminates, by additional defrosting operating function FK2
When detecting the temperature decline of vaporizer 11, it is judged that need to carry out adding defrosting operation, and at warp
The prolongation defrosting operation of defroster 13 is again driven after the second time, it is possible to effectively
The frost thawing that makes to melt the most completely.Even if this is because terminating but frost is the completeest in basic defrosting operation
Under the full state melted, after the driving of defroster 13 stops, the temperature of vaporizer 11 is because of residual
The frost that stays and be gradually reduced.
Additionally, frost substantially melts at the end of basic defrosting operation, though defrosting dress
Put after the driving of 13 stops, it is also possible to utilizing heater waste heat and under making the temperature of vaporizer 11 not
Fall.Therefore, temperature Te1 and the process to the vaporizer of (moment TM1) after the very first time
After stipulated time, temperature Te2 of (the moment TM2 after the second time) compares, and confirms
During Te1 >=Te2, it is judged that need to carry out extending defrosting and operate.
Additionally, after the prolongation defrosting operation of step S6 starts, in step S6A, it is judged that evaporation
Whether temperature Te of device is more than the first temperature TX, if "Yes", then and can be to Y-direction
Advance, make prolongation defrosting operation stop (step S7) and return generally controls (step S8).
In step S6A, if "No", then advance to N direction, it is judged that when driving lasting
Between whether arrive the 3rd time (moment TM3) (step S6B).In step S6B, if
For "No", then advance to the N direction of figure and return step S6A, if "Yes", then to
Y-direction is advanced, and makes prolongation defrosting operation stop (step S7).
Such as, as the CA21 shown in Fig. 7, in basic defrosting operation sequence, arrive first
During temperature TX, basic defrosting operation stops.Additionally, as CA22, although in basic defrosting
Temperature Te1 of the vaporizer 11 of the moment TM1 at the end of operation does not arrives the first temperature TX, but
It is higher than temperature Te1 in temperature Te2 of the vaporizer 11 of the moment TM2 after the second time
Time, only it also is able to utilize waste heat effect to make after defroster 13 stops even if being equivalent to residual frost amount
The state of the degree that the temperature of vaporizer rises, so not carrying out extending defrosting operation and returning generally
Control.
But, the situation of CA23 is, at the vaporizer of the moment TM1 that basic defrosting operation terminates
Temperature Te1 of 11 does not arrives defrosting end temp, and during the stopping of defroster 13,
The situation that the temperature of vaporizer 11 declines, this is equivalent to residual frost amount and more to utilizes defroster 13 to stop
The state of the degree that the waste heat after Zhi can not melt.In this case, by additional defrosting operation
Function FK2, the moment TM1 terminated from basic defrosting operation through the stipulated time through second
Moment TM2 after time, drives defroster 13 again, starts to extend defrosting operation.Above-mentioned
In the case of, when the temperature of vaporizer 11 arrives defrosting end temp (the first temperature TX), also same
Sample makes prolongation defrosting operation stop.
It addition, in the present embodiment, according to the evaporation to the moment TM1 that basic defrosting operation terminates
Temperature Te1 of device 11 and after the stipulated time (the moment TM2 after the second time)
The result that temperature Te2 of vaporizer 11 compares, it may be judged whether need to carry out extending defrosting operation,
But be not restricted to that this, such as, Te1 can be through regulation after basic defrosting operation terminates
After time, additionally, Te2 can be the time specified the most in advance compared with through the second time.
Additionally, replace Te1 and Te2 is compared, can be according to from moment TM1 to moment TM2
The variations in temperature tendency of the temperature of the vaporizer 11 in the regulation moment of period, it may be judged whether need to carry out
Extend defrosting operation.
Then, each embodiment of the control after extending defrosting operation is illustrated.Embodiment 3
The most again extending defrosting operation after extending defrosting operation, embodiment 4 is extending defrosting
Defrosting program next time is changed, under embodiment 5 changes after again extending defrosting operation after operation
Defrosting program once.Therefore, above-described embodiment 3～5 can with in above-described embodiment 1,2
Any one is combined.
＜ embodiment 3 ＞
Then, the flow chart shown in Fig. 8 and the sequential chart shown in Fig. 9 are utilized, by below embodiment
Illustrating as embodiment 3, this embodiment is the completeest for frost at the end of detecting prolongation defrosting operation
During the temperature information entirely melted, it is judged that need to carry out further adding defrosting operation and again prolonging
Long defrosting operation.Fig. 8 only represents that the defrosting operation that extends from step S6 starts leading to step S8
The additional defrosting operation sequence often controlled.
After the prolongation defrosting operation of step S6 starts, in step S6A, it is judged that the temperature of vaporizer
Whether degree Te is more than the first temperature TX, if "Yes", then advances to Y-direction, makes to prolong
Long defrosting operation stops (step S7) and return generally controls (step S8).
If being "No" in step S6A, then advance to N direction, it is judged that drive the persistent period
Whether arrive the 3rd time (moment TM3) (step S6B).If being "No" in step S6B,
Then advance and return step S6A in the N direction in figure, if "Yes", then before Y-direction
Enter, make prolongation defrosting operation stop (step S7).
After extending defrosting operation stopping (step S7), it is judged that the temperature of the vaporizer 11 of moment TM3
Degree Te3 lower than the second temperature TA (step S7A), in the case of "Yes", to Y
Advancing in direction, at moment TM4 (after the 4th time SP2) after the stipulated time, opens
Begin again to extend defrosting operation (step S7B) (suitable with the CA33 of Fig. 9).Additionally, such as
Fruit is "No" in step S7A, then advance to N direction, does not implement again to extend defrosting operation,
Return step S8 generally controls (suitable with the CA32 of Fig. 9).
Start to the prolongation again of step S7C to defrost to grasp from the defrosting operation that again extends of step S7B
Make the execution step that stops identical with step S6～step S7, as long as change driving persistently time
Between step.
Thus, as shown in the CA33 of Fig. 9, even if arriving the moment extended at the end of defrosting operation
TM3, when temperature Te (Te3) of vaporizer is also not less than the second temperature TA, from moment TM3
Moment TM4 after the stipulated time (stopping period SP2) starts, grow to through the 5th time most
During moment TM5 after between, i.e. extend the period of defrosting operation period H3, again extend
Defrosting operation.
As it has been described above, in the present embodiment, it is characterised in that performing defroster 13 again
Moment TM3 after the 3rd time after driving, when making again to drive stopping, stopping again driving
After Zhi after predetermined 4th time (moment TM4), the most again drive
The defrosting operation of prolongation again (have and again extend defrosting operating function) of defroster 13.That is,
Even if arriving the moment after the 3rd time driving end forcibly making defroster 13
TM3, when temperature Te of vaporizer is also not less than the second temperature TA, extends defrosting behaviour again
Make.According to this configuration, after basic defrosting operation, play prolongation defrosting operating function and again drive
Dynamic defroster 13, when the temperature of vaporizer 11 does not rises, it is judged that need further to be chased after
Add defrosting operation and the most again drive defroster 13, it is possible to effectively further make not
The frost thawing melted completely.
It addition, in the present embodiment, the need of the judgement (step again extending defrosting operation
Rapid S7A) in, it is judged that whether temperature Te3 of the vaporizer 11 of moment TM3 is than the second temperature TA
Low, but it is that instead of in this, can be as step S5A of embodiment 2, S5B, according to the moment
The variations in temperature tendency of the vaporizer 11 of different two time point during TM3～moment TM4,
Judge whether that needs extend defrosting operation again.
＜ embodiment 4 ＞
Then, utilize the sequential chart shown in the flow chart of Figure 10 and Figure 11, below embodiment is made
Illustrating for embodiment 4, this embodiment frost at the end of detecting prolongation defrosting operation is the most complete
During the temperature information melted, change defrosting program next time.Above-mentioned embodiment changes Fig. 3 institute
The drive condition of the defroster 13 suitable with thick line L1 shown also carries out defrosting operation next time.
Additionally, Figure 10 only represents that the defrosting operation that extends from step S6 starts the usual control to step S8
Additional defrosting operation sequence.
After the prolongation defrosting operation of step S6 starts, in step S6A, it is judged that the temperature of vaporizer
Whether degree Te is more than the first temperature TX, if "Yes", then advances to Y-direction, makes to prolong
Long defrosting operation stops (step S7) and return generally controls (step S8).
If being "No" in step S6A, then advance to N direction, it is judged that drive the persistent period
Whether arrive the 3rd time (moment TM3) (step S6B), if "No", then to figure
N direction advance and return step S6A, if "Yes", then to Y-direction advance, make
After extending defrosting operation stopping (step S7), carry out programing change operation (step S7D) that defrosts
And return generally control (step S8).
Such as, the CA33 (with reference to Fig. 9) shown in embodiment 3, extend even if arriving
Moment TM3 at the end of defrosting operation, temperature Te (Te3) of vaporizer is also not less than the second temperature
During degree TA, it is possible to judge that the frosting degree of vaporizer 11 much or is in the easy frosting of vaporizer 11
Environment (having put into food or refrigerator doors 3a, the opening time length etc. of 4a of high humidity in refrigerator).
In this state, even if carrying out next with the defrosting step as embodiment 1 or embodiment 2
Secondary defrosting, it is also difficult to remove the frost of vaporizer 11.
Therefore, in the present embodiment, it is judged that when being in above-mentioned state, by changing the behaviour that substantially defrosts
Make operation OP1 or add the defrosting program of defrosting operation sequence OP2, improving defrosting ability, it is possible to
Remove the frost of vaporizer 11 more reliably.
