Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, with reference to the accompanying drawing and specific real
Applying mode, the present invention is described in further detail.
Firstly, doing brief introduction to the prior art:
Washing-drying integral machine is that one kind increases drying function on the basis of automatic washing machine, and fusion laundry, drying, drying are more
Kind function is in the novel intelligent washing machine of one.
In existing technology, the drying judgment method of washing-drying integral machine is broadly divided into two major classes, and one kind is detection judgement temperature
Degree, another kind of is that detection judges humidity.Such as application No. is 200510114781.8 Chinese patents, disclose a kind of judgement drying
The dry method of machine drying object, comprising: 1) detect environment temperature Ts；2) dryer air outlet temperature Tc is detected；3) step is calculated
It is rapid 2) measured by temperature and step 1) measured by temperature gap Ts-Tc；4) by the step 3) difference and predetermined value T0 ratio
Compared with；When the difference is greater than the predetermined value, then enter next step；5) judge that clothing has been dried.Above-mentioned technical proposal passes through
Temperature is detected, realizes that the drying to clothing judges.In addition humidity sensor is placed on roller air outlet by a kind of washing-drying integral machine, is led to
The degree of drying for detecting and judging clothing by the air humidity of clothing from roller is crossed, i.e., realizes the baking to clothing by humidity
Dry judgement.
But the temperature sensor or humidity sensor used in the above scheme, it is poor to there is service precision, rapid wear
The case where consumption, this allows for washing-drying integral machine using the above scheme, and being easy to appear drying terminates the problem of judgement inaccuracy, makes
It is insufficient at clothes drying or clothing is excessively dried and damages clothing.
In addition, humidity sensor price is relatively expensive, the cost increase of washing-drying integral machine is caused, and be easy by environment
The influence of humidity.
For this purpose, being used the present invention provides drying judgment method, device and the washing-drying integral machine of another washing-drying integral machine
To solve the above problems.
Before being illustrated to technical solution provided in an embodiment of the present invention, first to the construction of washing-drying integral machine and work
Principle (drying part) is briefly introduced.
Referring to Fig. 1, Fig. 1 is a kind of sectional view of washing-drying integral machine provided in an embodiment of the present invention.As shown in Figure 1, washing
The working principle of drying integral machine are as follows:
The air for the drying high temperature that heating tube 13 heats is blowed to roller, while motor by upper air duct 12 by AC blower fan 14
9 drive inner cylinder 6 to rotate, and are thrown wet wash 5 by lifting rib 4, and the air of dry high temperature takes away moisture by wet wash 5, become
At the humid air of medium temperature, the condensed water that air duct enters with inlet valve 1 after the humid air warp of medium temperature exchanges heat, will be in humid air
Vapor condensation become water by outer barrel 7, scupper hose 8, reach draining pump 10, above-mentioned water is passed through draining by draining pump 10
Pipe 11 is discharged, and medium temperature humid air becomes the slightly dry air of low temperature after heat exchange and returns to AC blower fan 14, then exchanges wind
Machine blows to heating tube 13, and becomes the air of dry high temperature, so recycles, clothing is gradually dried.In addition, washing-drying integral machine is also
Including rear air duct 2 and cabinet 3.
It should be noted that invention thinking of the invention is that inventor thinks deeply just by creatively discovery and creatively
It obtains.
Specifically, referring to Fig. 2, Fig. 2 is the variation diagram of washing-drying integral machine drying course underpants amount of substance.As shown in Fig. 2,
Inventor contemplates washing-drying integral machine drying course underpants' amount of substance with the reduction of moisture first, can gradually decrease, clothing base
When this is in drying regime, quality almost no longer changes.That is, the moisture in clothing is fewer and fewer with the progress of drying,
The quality m of clothing is smaller and smaller, and rate of change is slower and slower, and the quality m of clothing no longer changes substantially when reaching dry.
Then, the detent torque for expecting motor of inventor's creativeness and the quality of clothing are positively correlated.Specifically, according to
Motor drives clothing to accelerate to n rpm rotation with β rpm/s, and when electric motor starting needs to overcome the drag torque T of clothing, and according to T
=mR2β, R and β is fixed when due to each electric motor starting, so the quality m of detent torque T and clothing is positively correlated.It please refers to
Fig. 3, Fig. 3 are the variation diagram of electric motor starting torque in washing-drying integral machine drying course.As shown in figure 3, with the progress of drying, electricity
Machine detent torque T is identical with the variation tendency of quality m.
Then, what inventor was creative expects that electric motor starting torque and electric motor starting electric current i are also positively related.It please refers to
Fig. 4, Fig. 4 are the variation diagram of electric motor starting electric current in washing-drying integral machine drying course.As shown in figure 4, electric motor starting electric current i with
The progress of drying, it is smaller and smaller, and change rate is slower and slower, when reaching dry, no longer changes substantially.
Discovery of the inventor based on above-mentioned creativeness, summarizes by many experiments, proposes following embodiments.
Embodiment

A specific example is named the technical solution of the embodiment of the present invention is described in detail.
After washing-drying integral machine drying starts, motor is turned to stop than rotation by certain, such as rotates forward 25s with n rpm, stops 5s,
25s is inverted, stops 5s, rotates repeatedly, controller acquires the starting current rotated and reverse every time since drying, and calculates
The average value of the two, as the electric current i1 of a cycle (include motor rotate forward and an adjacent motor reversal),
Then so collect i2, i3 ..., in-1, in, successively calculate judge i2-i1, i3-i2 ..., in-in-1, and divide
It does not make comparisons with preset Δ i, if the difference of the average current of the average current and previous cycle in latter period is less than or equal to Δ i
It then can be regarded as a virtual value, meet A virtual value when determining and then show clothing drying, drying terminates, and stops machine, such as
Fruit is unsatisfactory for, then continues to dry, until meeting above-mentioned condition.
The rule for having found the starting current of clothing quality and motor and being positively correlated of present inventor's creativeness, warp
The experiments for crossing a large amount of creativeness, obtained the starting current based on motor determine clothing whether be in drying regime technology
Scheme, that is, after washing-drying integral machine enters oven-dried condition, obtain starting current when motor starts every time, calculate continuous every
