When, refrigerate indoor temperature change, wherein C1 point is that indoor temperature is refrigerated when refrigerator doors are opened, and D1 point is refrigerator doors opening
Indoor temperature, about 20 DEG C are refrigerated after two hours.Figure 4, it is seen that after refrigerator doors are opened two hours, refrigerating chamber
Interior temperature maintains 20 DEG C or more.Therefore, can reflect whether refrigerator doors are opened and ice using temperature in refrigerator cold-storage room
Environment locating for case.It should be noted that the case where causing temperature change in refrigerator cold-storage room does not only have whether refrigerator doors are opened,
Here, being not listed one by one.In addition, it will be appreciated by persons skilled in the art that being reflected using the temperature in refrigerating chamber of refrigerator
Whether refrigerator doors open so that the refrigerator and can not perceive that method in this embodiment is suitable for perceive whether door is opened
The refrigerator whether door is opened.In addition, in the case where opening refrigerator, if environment locating for refrigerator is the environment of high temperature and humidity
Words, then can pour into a large amount of moistures in refrigerator, on an evaporator frosting.To sum up, it can reflect that consumer is practical with temperature in refrigerating chamber
Using the case where refrigerator and environment locating for refrigerator, reflect evaporimeter frosting degree.In turn, environment temperature locating for refrigerator is detected
Degree, the operating status for calculating compressor and runing time, the difference for calculating temperature in refrigerating chamber and default temperature in refrigerating chamber,
And judge whether the environment temperature, the operating status of compressor and the runing time that detect and the difference of calculating meet default item
Part illustrates that refrigerator is in the standard defrost period and not can solve the problem of evaporator cannot be dredged if meeting, as a result, according to inspection
The operating status and runing time and the difference of calculating of the environment temperature, compressor that measure are all from standard defrost by the defrost period
Phase is adjusted to predetermined period, and wherein predetermined period is less than the standard defrost period, to remove devaporation in time by shortening the defrost period
Frosting on device solves the problems, such as that evaporator cannot be dredged.Evaporimeter frosting degree is grasped in this way, realizing, according to evaporator
Frosting degree adjust refrigerator the defrost period, in time defrost, dredge evaporator, solve case in freeze the problems such as, greatly improve
Refrigerator quality.
In embodiments of the present invention, according to environment temperature, operating condition and runing time and temperature in refrigerating chamber and/or steaming
The defrost of hair device temperature control refrigerator, which may also include that, judges whether environment temperature is greater than preset temperature value；It is greater than in environment default
In the case where temperature value, judge whether operating condition is to continuously run and whether runing time is greater than preset time value；It is transporting
Turn state be continuously run and runing time be greater than preset time value in the case where, judge whether evaporator temperature is less than default steaming
Send out device temperature value；And in the case where evaporator temperature is less than default evaporator temperature values, control refrigerator starts defrost.Its
In, preset temperature value can be 13 DEG C, and preset time value can be 2h, and default evaporator temperature values can be -30 DEG C.
Fig. 3 be another embodiment of the present invention provides for control refrigerator defrost method flow chart.Such as Fig. 3 institute
Show, this method comprises:

Step S31: the operating condition and runing time of compressor are determined, that is, determine the operating condition of the compressor of refrigerator
And runing time；
Step S32: detection evaporator temperature；
Step S33: judging whether environment temperature is greater than preset temperature value, if so then execute step S34, if otherwise executing step
Rapid S37；
Step S34: judge whether it is continuously run and runing time be greater than preset time value, that is, be greater than in environment temperature
In the case where preset temperature value, judge whether the operating condition of compressor is to continuously run and whether is the runing time of compressor
S37 is thened follow the steps if not greater than preset time value if so then execute step S35；
Step S35: judge whether evaporator temperature is less than default evaporator temperature values, that is, transport to be continuous in operating condition
Turn and runing time is greater than in the case where preset time value, judges whether evaporator temperature is less than default evaporator temperature values, if
It is to then follow the steps S36, thens follow the steps S37 if not；
Step S36: control refrigerator starts defrost, that is, in the case where evaporator temperature is less than default evaporator temperature values,
Control refrigerator starts defrost；And
Step S37: control refrigerator enters the standard defrost period, wherein the standard defrost period is related with refrigerator, such as can be with
It is 8 hours, 10 hours, 12 hours, 24 hours etc..
In this embodiment, with the frosting degree of evaporator temperature reflection evaporator, the frosting degree and consumption of evaporator
It is related with environment locating for refrigerator that person actually uses the case where refrigerator.For example, and refrigerator is in high temperature and humidity if opening refrigerator doors
If environment, then a large amount of moistures in refrigerator can be poured into, frosting on an evaporator blocks evaporator, the temperature decline of evaporator.?
In the case that refrigerator operates, the time for opening refrigerator doors is longer, and the temperature fall of evaporator is bigger.Fig. 5 is of the invention another
Evaporator temperature when using refrigerator at a certain temperature that one embodiment provides changes schematic diagram.In Fig. 5, broken line represents evaporation
The variation of device temperature.A2 represents refrigerator in stable operation to the broken line between B2, the situation of change of evaporator temperature, from Fig. 5
In as can be seen that evaporator temperature maintain between -25 DEG C~-20 DEG C.When E2 represents refrigerator doors opening to the broken line between F2,
Evaporator temperature variation, wherein C2 point is evaporator temperature when refrigerator doors are opened, and evaporator temperature reaches -32 DEG C when D2 point.From
In Fig. 5 as can be seen that during refrigerator doors, evaporator temperature can reach -32 DEG C or less.The temperature of evaporator reflects refrigerator doors
Whether open and refrigerator locating for environment, reflect the frosting degree of evaporator.It should be noted that causing evaporator temperature
The case where variation, does not only have whether refrigerator doors are opened, here, being not listed one by one.In addition, it will be appreciated by those skilled in the art that
It is to reflect whether refrigerator doors are opened so that method in this embodiment is suitable for whether door can be perceived using evaporator temperature
The refrigerator of opening and the refrigerator whether door is opened can not be perceived.In turn, it detects environment temperature locating for refrigerator, calculate compressor
Operating status and runing time, and judge the environment temperature, the operating status of compressor and the runing time that detect and
Whether evaporator temperature meets preset condition, illustrates that refrigerator is in the standard defrost period and not can solve evaporator not if meeting
The problem of capable of dredging, controls refrigerator as a result, and is directly entered defrost, to remove the frosting on evaporator in time, solves evaporator not
The problem of capable of dredging.Evaporimeter frosting degree is grasped in this way, realizing, the defrost of refrigerator is adjusted according to the frosting degree of evaporator
Period, control refrigerator are directly entered defrost, defrost in time, dredge evaporator, solve the problems such as freezing in case, greatly improve refrigerator
