Drying control method and the washing machine of the washing machine that the embodiment of the present invention proposes are described below in conjunction with the accompanying drawings.
Fig. 1 is the flow chart of the drying control method of the washing machine according to the embodiment of the present invention.
As it is shown in figure 1, the drying control method of the washing machine of embodiment of the present invention proposition, comprise the following steps:
S1, after washing machine receives drying order, the heater controlling washing machine is opened to carry out heating work.
In one embodiment of the invention, washing machine can be the roller washing machine with drying function, the heating of this washing machine
Device can enter the air of interior bucket to carry out condensing drying work by heating.Specifically, heater can be by the sky of surrounding
Gas is heated into dry hot-air, and dry hot-air becomes the most clammy air after entering interior bucket, clammy air passes through
Condenser becomes dry cold air, and the moisture being simultaneously condensed out is expelled directly out by drain pipe.And the cold air being dried is again
Become bucket in dry hot-air enters by heater, so circulate, constantly the dampness of interior bucket undergarment is drained,
Thus reach to dry the purpose of medicated clothing.
S2, the in real time temperature of the interior bucket of detection washing machine.
S3, the temperature variations of bucket in obtaining according to the temperature of the in real time interior bucket of detection, and according to the temperature of interior bucket and interior bucket
Temperature variations the heating power of heater is adjusted.
At the beginning of heater is opened, the temperature of interior bucket can constantly rise.For making the temperature of interior bucket rise rapidly, to improve baking

Specifically, can determine whether whether the temperature variations of interior bucket is in ascendant trend, and judge whether the temperature of interior bucket is less than
First preset temperature, if the temperature that the temperature variations of interior bucket is in ascendant trend and interior bucket is less than the first preset temperature,
Then control heater to preset heating power with first and carry out heating work.Wherein, heating power can be preset by first to be set to
One relatively large value.
Usually, during heater carries out heating work with certain heating power, the temperature of interior bucket constantly rises,
And slowly decline after reaching inflection temperature.Should be appreciated that the heating power of heater is the highest, inflection temperature is the highest, also
That is, if heater continues to preset heating power with first carries out heating work, the temperature of interior bucket may reach one
Individual higher value, so likely results in the damage of medicated clothing.Therefore, when the temperature variations of interior bucket is in ascendant trend,
The heating power of heater can be reduced when the temperature of interior bucket raises to above equal to the first preset temperature, i.e. control heating
Device is preset heating power with second and is carried out heating work, until the temperature variations of interior bucket is not in ascendant trend, wherein,
Second presets heating power presets heating power less than first.So, preset heating power at heater with second to add

Specifically, heater with the 3rd preset heating power carry out heating work time, can be according to the interior bucket of in real time detection
Temperature, the temperature change value of bucket in obtaining in preset time period.Pre-more than second at the absolute value of the temperature change value of interior bucket
If during value, if only considering from the angle of variations in temperature, the fall off rate of the temperature of interior bucket is very fast, thus is still to continuous heating,
To slow down the fall off rate of the temperature of interior bucket, it is ensured that drying efficiency；But owing to the absolute value of the temperature change value of interior bucket is less than
Equal to the first preset value, the angle in conjunction with variations in temperature with energy consumption considers, with the electric energy that currently consumed to remain current
Temperature fall off rate is calculated not, thus the heating power of heater can be further reduced to the 4th preset add hot merit
Rate, to reduce the consumption of electric energy further.And if the absolute value of the temperature change value of interior bucket is less than or equal to the second preset value,
The temperature-visualized of interior bucket is for being basically unchanged, and this does not the most occur the steam of heat exchange in showing interior bucket, thus can control
Heater stop works.
It should be noted that above-mentioned first to fourth presets heating power, the first preset temperature, the first preset value and second
Preset values etc. all can set according to conditions such as the thermostabilitys of the parameter of heater, the capacity of washing machine and medicated clothing.
The drying control method of washing machine according to embodiments of the present invention, by the temperature of the interior bucket of detection washing machine in real time, and
Temperature according to interior bucket obtains the temperature variations of interior bucket, then according to temperature and the temperature variations pair of interior bucket of interior bucket
The heating power of heater is adjusted, thus, it is simple to regulates according to demand for heat actual in drying course and adds hot charging
The heating power put so that the heating power of heater matches with actual demand for heat, it is to avoid heating power is relative to mistake
Low or the most too high, thus the drying efficiency of washing machine can not only be improved, additionally it is possible to reduce the consumption of electric energy in drying course,

Then return previous step, continue to heat with P2；If it is, temperature Ti of interior bucket reaches maximum, i.e. in Fig. 3
Inflection temperature T2, then can perform step S207.
S207, is set as P3 by the heating power of heater.Wherein, P3 ＜ P2.
S208, in the time of record Δ t, variation delta T of temperature Ti of interior bucket.
S209, it is judged that whether Δ T is more than Δ T1.If it is, as it is shown on figure 3, variations in temperature is still very fast, can return to
One step, continues to heat with P3；If it is not, then as it is shown on figure 3, variations in temperature is relatively slow, step can be performed
S210。
S210, is set as P4 by the heating power of heater.Wherein, P4 ＜ P3.
S211, it is judged that whether Δ T is less than or equal to Δ T1 and more than Δ T2.If it is, as it is shown on figure 3, variations in temperature phase
To slowly, can return to previous step, continue to heat with P4；If it is not, then as it is shown on figure 3, temperature is almost unchanged,
Step S212 can be performed.
S212, stops heating, to terminate drying work.
Thus, drying work is started with of a relatively high P1, it is possible to increase the climbing speed of the temperature of interior bucket such that it is able to carry
High drying efficiency, in the drying course after temperature rises to T1, heating power is gradually lowered as P2, P3 and P4 successively,
The consumption of electric energy can be reduced.
