Specific embodiment
The present invention will be described in more detail with reference to the accompanying drawings and examples.
Describe refrigerator involved in the present invention in detail referring to the drawings preferred embodiment.
Additionally, in the description of the drawings, same symbol is accompanied by same or considerable part, weight is omitted
Multiple explanation.
(the 1st implementation method)
Fig. 2 is the floor map of the refrigerator 100 for representing the 1st implementation method of the invention.
As shown in Fig. 2 the refrigerator 100 of first embodiment of the present invention possesses：Multiple compartments
10~12；Evaporator 20, freezes to compartment 10~12；Fan 30, enters to evaporator 20
Row blowing；And air channel 40, the wind blown out by fan 30 is guided to compartment 10~12, and
Possess in the compartment 10~12 at least one air outlet 15,17,19 and at least one return air inlet 14,
16th, 18, it is circulated the wind path in compartment 10~12.In the example of Fig. 2, refrigerator 100
It is three tradition of a family cold refrigerators, it is respectively refrigerating chamber 10, temperature-changing chamber 11 and refrigerating chamber from top to bottom
12.The air channel 40 at the back side of refrigerator 100 connects evaporator 20 with each compartment 10~12.
Cold wind is blown to demand according to each compartment temperature each interior respectively.Each compartment and wind
The position of road connection can possess baffle plate (not shown), and in refrigeration, baffle plate is opened cold to ensure
Wind is blown into this interior, when that need not freeze, flapper closure, so as to cut off being blown into for cold air.
At at least one air outlet 15,17,19 of refrigerating chamber, temperature sensor 41 is provided with.
Its temperature change being used at detection air port.The baffle plate of the compartment in air channel is in open shape
In the case that the door of state and compartment is not opened and closed, when the temperature detection of the temperature sensor 41
When value increases to over set point of temperature at the appointed time, it is judged to that evaporator 20 occurs the stifled feelings of frost
Condition.Described frost is blocked up herein, refers to that the vapor in air condenses simultaneously to the cold on evaporator 41
The phenomenon for freezing.These ice block the gap between the fin of evaporator 20, so as to hinder
Hinder the flowing of air, cause the amount of air outlet blowing cold air to reduce.Thus, refrigeration drop
It is low, and refrigerator energy consumption rise.After being judged to that evaporator occurs the stifled situation of frost, just enter
The defrosting treatment of row evaporator.
Preferably, in the example of present embodiment, temperature sensor 41 is arranged in air outlet
The air outlet 19 farthest apart from evaporator at.Due to there is the stifled situation of frost in evaporator 20
Under, the amount for sending out cold wind reduces, particularly at the air outlet 19 farther out of evaporator 20,
The degree that air quantity reduces is more obvious.Therefore, it is arranged in air outlet by by temperature sensor
The air outlet farthest apart from evaporator at, can more fast and effeciently judge evaporator send out
The stifled situation of raw frost.In this example, temperature rises 3 in T3 at refrigerating chamber distalmost end air outlet
More than degree, then it is judged to that evaporator there occurs that frost is stifled.Herein, T3 refers to be implemented according to the present invention
The time that the judgement frost of mode is blocked up, for example, 15min~30min.
Fig. 3 is the flow chart of the defrosting control method of the refrigerator 100 of the 1st implementation method.In wind
In the case that the baffle plate of refrigerating chamber 10 in road is opened, and in refrigerating chamber 10 without opening and closing
In the case of operating, whether judgement is arranged at temperature that the temperature sensor at air outlet detected
Be increased beyond set point of temperature in the stipulated time, be judged to it is eligible in the case of, then judge
It is stifled to there occurs evaporator frost, and defrosted.Preferably, the stipulated time herein be
15~30min, set point of temperature herein is 2~4 degree, by being arranged in such scope, energy
Enough situations for effectively judging that evaporator frost is stifled.
In the example of present embodiment, as long as temperature is in T3 (examples at refrigerating chamber distalmost end air outlet
Such as 20min) in rise more than 3 degree, so that it may judge that frost occurs to be blocked up.With need T1+T2 (for example
80 minutes or so) judge to be compared in the stifled prior art of frost, only need T3 (e.g., from about 20 minutes)
Just can obtain result of determination.Greatly reduce the time required for judging.Additionally, in this implementation
In mode, in the case where being judged to that evaporator frost is stifled, do not carry out at precooling of the prior art
Reason.Because, as a result of the defrosting control of present embodiment, can find earlier
The stifled situation of frost, the temperature in this time room is also unlikely to rise too high, therefore need not carry out low
In the precooling treatment of predetermined temperature.Further, since being judged to that evaporator is occurred in that
The stifled phenomenon of frost, refrigerating efficiency has been substantially reduced, and now continues to increase refrigeration intensity on the contrary, only
Extra energy consumption can be increased and expected refrigeration cannot be obtained.
Fig. 4 is the figure of the defrosting control effect of the refrigerator 100 for illustrating the 1st implementation method.Fig. 4
Show refrigerating chamber air outlet temperature in the usual operation of refrigerator, refrigerating chamber indoor temperature, cold
Freeze the curve of the temperature of room air outlet temperature, refrigerating chamber indoor temperature and evaporator.From Fig. 4
As can be seen that in normal refrigeration and refrigerating-chamber door in the interval of middle about 265 minutes~about 285 minutes
It is not opened and closed, and the temperature of refrigerating chamber air outlet is in lasting rising.And it rises
Climbing speed of the speed apparently higher than refrigerating chamber indoor temperature.Defrosting control according to present embodiment
Method processed, just can determine that evaporator there occurs the stifled situation of frost at about 285 minutes.If using
The method of traditional monitoring refrigerating chamber indoor temperature, then need the longer time can judge be
It is no to there occurs that frost is stifled.Additionally, be can be seen that in the interval of about 265 minutes~about 285 minutes
Even if there occurs the stifled phenomenon of frost, but had little to no effect for refrigerating chamber air outlet temperature.This is
Because refrigerating chamber air outlet is nearer away from evaporator, also unlikely in the case where just there is white blocking up
In the air output for having influence on refrigerating chamber.It is therefore preferred that temperature sensor 41 is arranged at cold
The compartment frozen beyond room, it is highly preferred that temperature sensor 41 to be arranged at the air outlet of refrigerating chamber
Place.
According to the refrigerator 100 of the 1st implementation method, passed by setting temperature at the air outlet in air channel
Sensor simultaneously determines Temperature ramp at air outlet such that it is able to find to steam earlier compared with prior art
The stifled situation of hair device frost, and defrosted in time after finding that frost is stifled such that it is able to improve refrigeration
Efficiency, reduces energy consumption.
(the 2nd implementation method)
Fig. 5 is the floor map of the refrigerator 200 for representing the 2nd implementation method of the invention.2nd
Implementation method 200 is with the difference of the 1st implementation method 100：Substitution temperature sensor 41 and
Air velocity transducer 42 is set at the air outlet of refrigerating chamber 10 in air channel, and works as air velocity transducer
42 detected value drops to when below the requirement ratio of benchmark wind speed at the appointed time, is steamed
Send out the defrosting treatment of device.
According to the refrigerator 200 of the 2nd implementation method, occur when frost is blocked up and refrigerating chamber baffle plate in evaporator
In open mode, fan remains in operation, and be sent at refrigerating chamber distalmost end air outlet (but not
Be limited to farthest air outlet) wind speed be greatly decreased.In the example of present embodiment, removed with last time
On the basis of mean wind speed after frost between 2 hours~4 hours value (but not limited to this, or
The mean wind speed value of any stabilization time section after defrosting), the wind speed at refrigerating chamber distalmost end air outlet
On the basis of reduction wind speed less than 50% when, and continue T3min (such as 20min), you can sentence
It is disconnected to have frost stifled, and proceed by defrosting.Additionally, the air velocity transducer 42 of present embodiment can be with
It is made up of such as piezo-resistance etc..
Fig. 6 is the flow chart of the defrosting control method of the refrigerator 200 of the 2nd implementation method.In wind
In the case that refrigerating chamber baffle plate in road is opened, and it is not opened and closed in refrigerating-chamber door and is operated
In the case of, judgement is arranged at whether the wind speed that the air velocity transducer at air outlet detected drops to
Below the requirement ratio of benchmark wind speed and persistently more than the stipulated time, be judged to it is qualified
In the case of, then it is judged to there occurs that evaporator frost is stifled, and defrosted.Preferably, herein
Requirement ratio is 40%~60%, it is stipulated that the time is 15~30min, by being arranged on such scope
It is interior, can effectively judge the stifled situation of evaporator frost.
