The actual frosting degree added up on one evaporimeter 251, by the frosting degree control except defrosting system is more accurate.In the same manner, the second evaporation
The actual frosting degree of device 252 calculates also more accurate.
It is described except defrosting system is received to the finger of the first evaporimeter 251 or the defrosting of the second evaporimeter 252 in above two method
When making, if the evaporimeter 252 of first evaporimeter 251 or second is in refrigerating state, into defrost after the completion of refrigeration
Journey；If the first evaporimeter 251 or the second evaporimeter 252 are not in refrigerating state, into defrost process.The end point of defrost
Judge to adopt technological means commonly used in the art.
It will be appreciated by persons skilled in the art that total humidity Ha is the aggregate-value in a defrost cycle, and each is changed
The first blower fan 201 in the white cycle is not to operate always, namely return air is not a continual process；It is above-mentioned exhausted
It is accumulated value when the first blower fan is rotated for more than 201 times to humidity H1.Ha in each run time period of first blower fan 201 can be by
Following method is calculated：In time period T1, the mean value H1, H1*T1 of the absolute humidity of the detection return air of the first humidity sensor 31
Integration calculates the absolute humidity total value in this time.Or, the Ha in each run time period of the first blower fan 201 can also divide

Value, the absolute humidity total value in the unit interval is calculated by formula H1*T1 integrations, then the humidity value in each time period is added
Obtain total humidity value Ha.The integral of Hb in the same manner, is repeated no more with Ha in this.
In addition, first refrigeration compartment 11 of the present invention not refers in particular to a single refrigeration compartment, and refer to and steamed by first
Send out a compartment or multiple compartments that device 251 provides cold.Correspondingly, the first corresponding humidity sensor 31 of multiple compartments,
The first ' humidity sensor 32 can be shared and can also be used alone；For example, first air delivery duct of part 261 or portion of multiple compartments
When dividing shared in the first air -return duct 281, the first humidity sensor 31 of multiple compartments, the first ' humidity sensor 32 can be shared
And be placed in general the first air -return duct of part 281 or the first air delivery duct of part 261.Again for example, the first of multiple compartments send
When air channel 261, the first air -return duct 281 are separately provided, the first humidity sensor 31, the first ' humidity sensor 32 are used alone.
Correspondingly, when the first refrigeration compartment 11 is multiple compartments, the frosting degree on the first evaporimeter 251 be multiple compartments frosting degree it
With；The computational methods of the frosting degree without compartment are same as above, repeat no more in this.
In sum, refrigerator 100 of the invention is by being arranged at first return air inlet 291 or first air -return duct
The first humidity sensor 31 in 281, can detect at from the return air of the first refrigeration compartment 11 to first evaporimeter 251
Return air humidity, the moisture through evaporimeter can be more precisely computed, such that it is able to accurately calculate first evaporimeter
Frosting degree on 251.
Above example is only unrestricted to illustrate technical scheme, although with reference to preferred embodiment to this
It is bright to be described in detail, it will be understood by those within the art that, technical scheme can be modified
Or equivalent, without deviating from the spirit and scope of technical solution of the present invention.

Defrosting system.
9. a kind of defrosting control method of the refrigerator for described in claim 7, it is characterised in that：Comprise the steps：
The absolute humidity H1 of the return air of first the first refrigeration compartment of humidity sensor real-time detection, the first ' humidity sensor is real-time
Detect the absolute humidity H1 ' of the air-supply of the first refrigeration compartment；
The absolute humidity H2 of the return air of second the second refrigeration compartment of humidity sensor real-time detection, the second ' humidity sensor is real-time
Detect the absolute humidity H2 ' of the air-supply of the second refrigeration compartment；
Master control borad obtains the accumulative fortune of compressor operating when the triple valve is respectively turned on first throttle element, the second restricting element
Row time T1, T2；
Master control borad integral and calculating is condensate in the total humidity cumulant Δ Ha=on the first evaporimeter（∫H1*T1）-（∫H1’*T1）；It is cold
Coagulate the total humidity cumulant Δ Hb=on the second evaporimeter（∫H2*T2）-（∫H2’*T2）；
When total humidity cumulant Δ Ha reaches the frosting degree H0 of the first evaporimeter, will be sent to the instruction of the first evaporimeter defrosting
It is described except defrosting system;When total humidity cumulant Δ Hb reaches the frosting degree H0 ' of the second evaporimeter, will defrost to the second evaporimeter
Instruction be sent to it is described except defrosting system.
10. the defrosting control method of refrigerator according to claim 8 or claim 9, it is characterised in that：The defrosting control of the refrigerator
Method also includes：It is described except defrosting system receive to the first evaporimeter or the second evaporimeter defrosting instruction when, if it is described first steam
Send out device or second evaporimeter is in refrigerating state, then into defrost process after the completion of freezing；If the first evaporimeter or
Two evaporimeters are not in refrigerating state, then into defrost process.
