Fig. 1 is a flowchart illustrating a method for detecting a moisture content of laundry according to an exemplary embodiment, which may include steps S110 to S170, described in detail as follows:

step S110: an initial electromagnetic wave is emitted toward laundry within the drum dryer, the initial electromagnetic wave having a first intensity and a first phase.

When the tumble dryer is drying laundry, an initial electromagnetic wave is transmitted to the laundry in the tumble dryer, and the frequency of the initial electromagnetic wave may be in the range of 300MHz-300GHz, but may be in other ranges.

In this embodiment, a microwave sensor may be disposed in the front support of the tumble dryer, and the microwave sensor may emit an initial electromagnetic wave into the inner drum of the tumble dryer in real time or at intervals when the tumble dryer is in operation, and the initial electromagnetic wave may have a predetermined phase and intensity, for example, the initial electromagnetic wave emitted to the laundry may have a first intensity and a first phase.

Step S130: and acquiring a second intensity and a second phase of the initial electromagnetic wave after the initial electromagnetic wave passes through the clothes.

Energy attenuation and phase shift occur when the initial electromagnetic wave passes through the laundry, and a second intensity and a second phase of the initial electromagnetic wave after passing through the laundry are recorded when the initial electromagnetic wave after passing through the laundry is received.

In this embodiment, the initial electromagnetic wave passing through the laundry is received by the internal microwave sensor disposed in the front support of the drum dryer, i.e. the initial electromagnetic wave passes through the laundry and reaches the microwave sensor and the opposite inner drum wall of the drum dryer, which is generally made of stainless steel, and reflects the electromagnetic wave, so that the electromagnetic wave passes through the laundry in the inner drum of the drum dryer again and returns to the microwave sensor again; certainly, a microwave sensor can be arranged at the position of the front support opposite to the inner drum to receive the initial electromagnetic wave passing through the clothes, namely, the initial electromagnetic wave passes through the clothes once, namely, the initial electromagnetic wave is received by another microwave sensor; of course, other methods may be used to receive the initial electromagnetic wave passing through the clothing, as long as the initial electromagnetic wave passes through the clothing, and this is not limited specifically here.

Step S150: determining a first attenuation amount caused by the initial electromagnetic wave passing through the clothes according to an attenuation value between the first intensity and the second intensity and a phase difference between the first phase and the second phase;

when the initial electromagnetic wave passing through the clothes is received, the intensity and the phase of the initial electromagnetic wave and the intensity and the phase of the initial electromagnetic wave passing through the clothes are analyzed, the attenuation value between the first intensity and the second intensity and the phase difference between the first phase and the second phase are obtained, and the first attenuation amount caused by the initial electromagnetic wave passing through the clothes is determined.

Step S170: and acquiring the water content of the clothes according to the first attenuation amount.

In this embodiment, the water content of the laundry in the drum type dryer is calculated based on the attenuation value and the phase difference; when the initial electromagnetic wave is emitted in real time and the initial electromagnetic wave passing through the laundry is obtained in real time, and the water content of the laundry in the tumble dryer is calculated through the two, a set of time and water content graphs in the drying process can be obtained, as shown in fig. 2, fig. 2 is a graph of time and water content in the tumble dryer in an embodiment, and according to continuous extension of the operating time of the tumble dryer, attenuation of the initial electromagnetic wave penetrating through the laundry is smaller and smaller, and the water content of the laundry obtained through the attenuation is smaller and smaller.

The method can detect the water content of the laundry without contacting the laundry by emitting an electromagnetic wave to the laundry in the drum-type dryer and receiving the intensity attenuation and the phase shift of the electromagnetic wave through the laundry, and can detect not only the dryness of the surface of the laundry but also the dryness of the inside of the laundry.

step S310: and acquiring a first voltage value corresponding to the first attenuation.

The phase difference and the attenuation value can be used to obtain a voltage value corresponding to the phase difference and the attenuation value, and specifically, a first voltage value corresponding to a first attenuation can be obtained by the electromagnetic wave and voltage conversion circuit.

Of course, in other embodiments, the voltage value a may be obtained by passing the first intensity and the first phase of the initial electromagnetic wave through an electromagnetic wave and voltage conversion circuit, the voltage value B may be obtained by passing the initial electromagnetic wave through the clothes through the electromagnetic wave and voltage conversion circuit according to the second intensity and the second phase of the initial electromagnetic wave, and a voltage value may be obtained according to the two voltage values A, B for the subsequent water content calculation; alternatively, when the initial electromagnetic wave with the same intensity and phase is used, the voltage values corresponding to the second intensity and the second phase of the initial electromagnetic wave passing through the clothes are directly used as the values for the subsequent calculation of the moisture content, which is not particularly limited herein.

Step S330: and acquiring the clothes water content corresponding to the first voltage value according to the mapping relation between the preset voltage value and the clothes water content.

And when the first voltage value is obtained, acquiring the water content of the clothes corresponding to the first voltage value according to a preset mapping relation between the voltage value and the water content of the clothes.

In this embodiment, a corresponding voltage value is obtained according to the attenuation of the electromagnetic wave, a water content is obtained according to the voltage value and the mapping relationship, and the electromagnetic wave signal is converted into a digital signal, so as to facilitate subsequent calculation of the water content.

Fig. 4 is a flowchart illustrating a method for sensing a moisture content of laundry, which may include steps S410 to S450, according to another exemplary embodiment, in detail as follows:

step S410: and acquiring a plurality of second attenuation amounts of the electromagnetic waves passing through the clothes with different water contents.

And in the step, the same electromagnetic wave can be used for penetrating through the clothes with known water content for multiple times to obtain the electromagnetic wave attenuation under the clothes with different water content, and multiple experiments are carried out to obtain a large amount of training data with the attenuation corresponding to the water content.

Step S430: and acquiring second voltage values corresponding to the plurality of second attenuation amounts respectively.

Voltage values corresponding to the large amount of attenuation obtained in step S410 are obtained, and the specific obtaining method may refer to step S310, so that a large amount of voltage values and corresponding water content data are obtained.

Step S450: and constructing a mapping relation according to the second voltage values respectively corresponding to the plurality of second attenuation amounts and the water content of the corresponding clothes.

And acquiring a mapping relation between the voltage value and the water content according to the obtained large number of voltage values and the corresponding water content, specifically, establishing a model frame between the voltage value and the water content, inputting the large number of voltage values and the corresponding water content data obtained in the step S430 into the model frame for training until the model converges, namely, when the humidity value obtained after the input voltage value passes through the model and the actual humidity value corresponding to the voltage value have an error within a preset threshold value, the model is used as the mapping relation between the voltage value and the water content.

In this embodiment, through the voltage value that acquires the correspondence of different water contents, train a large amount of voltage values and water content, obtain the mapping relation between voltage value and the water content, this mapping relation can be used to the measurement of the clothing water content in the drum-type clothes dryer in the actual work.

Fig. 5 is a flowchart illustrating a method for obtaining a first voltage value corresponding to a first attenuation amount according to an exemplary embodiment, where the method may include steps S510 to S530, which are described in detail as follows:

step S510: and amplifying the first attenuation amount to a preset multiple and then carrying out filtering processing.

The attenuation of the electromagnetic wave is amplified to a preset multiple and then subjected to wave filtering treatment to remove noise in the signal, so that an attenuation signal convenient for subsequent operation is obtained.

Step S530: and converting the first attenuation amount subjected to the filtering processing into a first voltage value.

In this step, the first attenuation after being preprocessed in step S510 is converted to obtain a voltage corresponding to the first attenuation, and the conversion process may be a method of performing peak measurement on the attenuation, sampling a peak voltage, and the like, and is not limited specifically here.

In this embodiment, the attenuation is amplified and filtered, so that conversion between the electromagnetic wave and the voltage value is facilitated, and a voltage digital signal which is convenient to calculate is obtained.
