In view of washing machine is during first drying, the material for drying clothing may be not quite similar, and wash for example, putting into
Clothing in clothing machine may include the various materials such as cotton goods, the linen fabrics, silk goods.As corresponding to the clothing of unlike material
Drying power and drying time it is different, therefore, when the different clothing of material is dried simultaneously, need obtaining
To multiple drying power and multiple drying times in, final drying power and drying time are determined, using as drying function
Rate setting value PsetWith drying time setting value Tset, used in subsequent drying course.
As a kind of preferred design of the present embodiment, when needs while the clothing of dry N kind material, preferably from N
In N number of drying power corresponding to kind clothing material, the smallest drying power P of performance number is selectedminAs the drying power
Setting value Pset.By cotton goods, three kinds of materials of the linen fabrics and silk goods clothing for be illustrated, it is assumed that cotton goods are suitble to
Drying power be 300W, the drying power that the linen fabrics are suitble to be 200W, the drying power that silk goods are suitble to be 100W, when
When needing that the clothing of these three materials is put into washing machine while being dried, the preferred the smallest drying power of performance number,
That is 100W drying power corresponding to silk goods, as drying set value of the power Pset, it is possible thereby to avoid heating temperature excessively high,
The fiber in silk goods is caused to cross thermal damage.
Due to having selected minimum value on drying power, in order to guarantee that the clothing of unlike material in washing machine is drying
It is attained by the state of substantially dry at the end of dry process, it is N number of dry corresponding to clothing of the present embodiment preferred pin to N kind material
The clothing time selects the maximum drying time T of time valuemaxAs the drying time setting value Tset.Still with cotton goods, hemp

In view of the weight correlation of drying time and clothing, if in the clothing of N kind material, drying time
Shorter clothing specific gravity shared in whole clothings is larger, then the clothing of these materials reaches above-mentioned drying in drying time
Time setting value TsetIt is just completely dried already before.Heating, drying is continued to the clothing being completely dried, clothes fiber can also be produced
It is raw to destroy.Conversely, if the longer clothing of drying time specific gravity shared in whole clothings is larger in the clothing of N kind material,
What it is due to the selection of drying power is minimum value, and the clothing of these materials reaches above-mentioned drying time setting value in drying time
TsetShi Keneng is also unseasoned, it is therefore desirable to the drying time setting value T determined using the above methodsetIt is finely adjusted.Specifically
Scheme is preferred are as follows:
From N number of drying time corresponding to N kind clothing material, value T based on the maximum drying time of time value is selected0;
The weight information of each clothing is acquired, the weight information can be extracted from label information, and count each material
The total weight of matter clothing;
If the total weight of material clothing corresponding to maximum drying time accounts for 50% or more of whole clothing total weights, such as cotton goods
Clothing account for the overwhelming majority, then can be by basic value T0Raising △ T, the △ T is adjustment time, preferred T=10 minute △, with
Determine final drying time setting value Tset=T0+△T;
If the total weight of material clothing corresponding to minimum drying time accounts for 50% or more of whole clothing total weights, such as silk goods
Clothing account for the overwhelming majority, then can be by basic value T0△ T is lowered, such as reduces 10 minutes, when determining final drying
Between setting value Tset=T0-△T;
If the total weight of material clothing corresponding to the total weight of material clothing corresponding to maximum drying time and minimum drying time
Shared specific gravity, which is respectively less than, in whole clothing total weights is equal to 50%, that is, when being not belonging to any one in above-mentioned two situations,
It can be by the basic value T0As final drying time setting value Tset, that is, drying time setting value Tset=T0。
For above-mentioned drying set value of the power PsetWith drying time setting value TsetDetermination, can be automatically complete by controller
At.
Power conditioning module and Anneta module are set in washing machine, as shown in figure 3, power conditioning module may be mounted at
The left shell of washing machine or the inside of right shell, and controller is connected by cable, the drying determined according to controller
Set value of the power PsetThe transmission power for adjusting Anneta module is equal to the power of the electromagnetic wave issued by Anneta module described
Drying set value of the power Pset.Anneta module is installed towards washing machine inner tub, so that the electromagnetic wave emitted by Anneta module
Clothing that can to the maximum extent in directive interior bucket.
As a kind of preferred antenna module mounting arrangement of the present embodiment, for rotary drum washing machine, as shown in Figure 1,
Anneta module 2 can be mounted on to the bottom of the upper cover plate 13 of rotary drum washing machine.In rotary drum washing machine to the clothing in its interior bucket 14
When object carries out drying and processing, upper cover plate 13 is fastened, at this time the clothing in 2 face interior bucket 14 of Anneta module, emits electromagnetic wave, internally
Clothing in bucket 14 is dried.For roller washing machine, washed as shown in Fig. 2, Anneta module 2 can be mounted on roller
The inside of the door body 23 of clothing machine.When roller washing machine carries out drying and processing to the clothing in its interior bucket 24, door body 23 is closed, this
When 2 face interior bucket 24 of Anneta module in clothing, emit electromagnetic wave, the clothing in interior bucket 24 is dried.Certainly, the day
Wire module 2 also may be mounted at the rear of the interior bucket 24 of roller washing machine, emit electromagnetic wave to the direction of interior bucket 24.Due to roller
Door body 23 cannot be opened washing machine during the work time, accordingly it is possible to prevent electromagnetic-wave leakage.
For washing machine after entering drying operational mode, controller controls the transmitting function that power conditioning module adjusts Anneta module
Rate is equal to drying set value of the power Pset, and timing is carried out to drying time T.When drying time T reaches drying time setting value
TsetWhen, controller controls Anneta module (or controlling Anneta module by power conditioning module) and stops transmitting electromagnetic wave, drying
Process terminates.
During the drying process, it is preferably provided with the electromagnetic wave of Anneta module transmitting fixed frequency, such as sends frequency and is
The uhf electromagnetic wave of 433MHz heats the moisture in clothing.Since water is compared with clothing, dielectric constant is different,
Under the radiation of 433MHz electromagnetic wave, the heat that water absorbs is big more than the heat that general clothing absorbs, therefore the moisture in clothing
Temperature quickly increases, volatilizees, and reaches drying effect.
To keep drying effect more uniform, washing machine preferably controls the rotation of its interior bucket during the drying process, stirs in interior bucket
Clothing, be heated evenly clothing.Meanwhile air duct can be set in washing machine and give subsystem, to form stream in interior bucket
Dynamic air, and then the steam steamed in wet wash is taken away, improve drying efficiency.
It, may also can to the fiber in clothing if being still under high-temperature baking in view of clothing is close to when being completely dried
Generate damage to a certain degree.In order to protect clothing, the present embodiment during the drying process, is examined the degree of drying of clothing
It surveys, when clothing mitigates clothing damage close to the transmission power of Anneta module, reduction heating temperature when drying, is reduced.When clothing
When through drying, if drying time T does not reach drying time setting value T alsoset, then control Anneta module and stop transmitting electromagnetic wave, mention
Preceding end drying course, preferably to protect the clothing in washing machine.
As a kind of preferred degree of drying judgment mode of the present embodiment, since the electromagnetic wave emitted by Anneta module exists
It can be reflected when touching clothing, and the energy of electromagnetic wave that the bigger clothing of humidity absorbs is more, the electromagnetic wave of reflection
Power is smaller;And the energy for the electromagnetic wave that the smaller clothing of humidity absorbs is fewer, the power of the electromagnetic wave of reflection is bigger.Therefore,
Based on this characteristic, the present embodiment receives the electromagnetic wave of clothing reflection using Anneta module, and the electromagnetic wave received is converted
At voltage transmission to controller, controller calculates the power of reflection electromagnetic wave according to the voltage received, is denoted as reception power
P2.Certainly, the calculating of power is received for antenna there are also many mature schemes, the present embodiment is not limited in the above citing.It will
The transmission power of Anneta module is denoted as P1, and when (P1-P2)/P1 drops to 10% or so, the present embodiment thinks the clothing in washing machine
Object is close to drying.At this point, controlling power conditioning module by controller reduces the transmission power of Anneta module, and then reduce heating
Temperature protects clothing.When (P1-P2)/P1 drops to 3% or so, the present embodiment thinks that the clothing in washing machine has been dried.
At this point, if drying time T does not reach drying time setting value T alsoset, then controller control Anneta module stops working, and ties in advance
Beam drying course, to can achieve while protecting clothing not to be damaged and save electric energy, the technology of energy waste is avoided to imitate
Fruit.

According to the material information of each clothing, material division, same material are carried out to the whole clothings put into washing machine
Clothing be classified as one kind, and count the total weight W of the clothing of every a kind of materiali, i=1,2 ... ..., N, wherein and N is positive integer,
To be used for subsequent drying time setting value TsetOptimization.
S404, drying power and drying time are determined according to the material information of clothing;
In the present embodiment, for the clothing of each material, drying power corresponding with the material clothing is determined respectively
PiWith drying time Ti, i=1,2 ... ..., N, to obtain N number of drying power and N number of drying time.
S405, drying set value of the power P is determinedsetWith drying time setting value Tset;
In the present embodiment, preferably from N number of drying power corresponding to N kind clothing material, the smallest drying of performance number is selected
Power is as the drying set value of the power Pset。
For drying time setting value Tset, the time can be selected from N number of drying time corresponding to N kind clothing material
It is worth maximum drying time as the drying time setting value Tset.It is of course also possible to the drying time setting value Tset
It advanced optimizes, to obtain more reasonable drying time setting value Tset, method particularly includes:
From N number of drying time corresponding to N kind clothing material, value T based on the maximum drying time of time value is selected0;
If the total weight of material clothing corresponding to maximum drying time accounts for 50% or more of whole clothing total weights, to the base
Plinth value T0It is raised, determines the drying time setting value Tset=T0+△T;
If the total weight of material clothing corresponding to minimum drying time accounts for 50% or more of whole clothing total weights, to the base
Plinth value T0It is lowered, determines the drying time setting value Tset=T0-△T;
If the total weight of material clothing corresponding to the total weight of material clothing corresponding to maximum drying time and minimum drying time
Shared specific gravity, which is respectively less than, in whole clothing total weights is equal to 50%, then by the basic value T0As the drying time
Setting value, i.e. Tset=T0。
S406, electromagnetic wave drying and processing is carried out to clothing, and the transmission power for adjusting electromagnetic wave is equal to the drying power
Setting value Pset;
Heating, drying processing is carried out to the clothing in washing machine using the electromagnetic wave of Anneta module transmitting, and passes through power regulation mould
The transmission power of block adjustment Anneta module reaches the drying set value of the power Pset.That is, being P using powersetElectromagnetic wave
Processing is thermally dried to the clothing in washing machine.
S407, timing is carried out to drying time T, if T < Tset, then subsequent process is executed;If T=Tset, then terminate to dry
Journey;
The duration for executing drying procedure to washing machine carries out timing, if drying time T has had arrived at the drying of setting
Between setting value Tset, then Anneta module can be controlled by controller and stops transmitting electromagnetic wave, terminate drying course.
S408, the degree of drying for detecting clothing, if clothing reduces the transmission power of electromagnetic wave close to drying;
It in the present embodiment, can be in conjunction with the function of the transmission power P1 and Anneta module of the Anneta module reflection electromagnetic wave received
Rate (that is, receiving power P 2), judges the degree of drying of clothing indirectly.It, can be with for example, as 3% < (P1-P2)/P1≤10%
It is judged as clothing close to drying.At this point it is possible to reduce the transmission power of electromagnetic wave, the protection to clothing is realized.In the present embodiment
