[0045] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

The singular terms "one" and "the" may also include plural forms.

[0047] The existing technology generally uses the resistance method or the capacitance method to measure the moisture content of clothes, but both methods have certain defects. The resistance method is to insert or clamp two electrodes into or clamp the clothes, and obtain the moisture content by detecting the resistance value of the clothes, but there is a large error in measuring the moisture content of clothes by the resistance method; the capacitance method is to use the clothes as a dielectric and measure its moisture content by measuring the dielectric constant of the clothes, but this method can measure a small range of moisture content.

[0048] To this end, the present invention provides a method for detecting moisture content of clothing, the method comprising: transmitting multiple first electromagnetic wave signals to the clothing to be tested in the washing device; receiving multiple second electromagnetic wave signals based on the reflection of the multiple first electromagnetic wave signals; determining the first signal attenuation rate based on the multiple first electromagnetic wave signals and the multiple second electromagnetic wave signals; and determining the moisture content of the clothing to be tested based on the first signal attenuation rate. The present invention can obtain the signal attenuation rate of the entire inner drum of the washing device by transmitting multiple first electromagnetic wave signals and receiving the second electromagnetic wave signals reflected by the multiple first electromagnetic wave signals, and then determine the moisture content of all the clothing in the washing device based on the signal attenuation rate. The moisture content of clothing can be measured without contacting the clothing, and the coverage of the moisture content measurement of clothing is improved by transmitting multiple signals, and the accuracy of the moisture content measurement is improved.

[0049] See attached Figure 1 , Figure 1 It is a flow chart of main steps of a method for detecting moisture content of clothing according to an embodiment of the present invention.

[0050] like Figure 1As shown, the method for detecting moisture content of clothing in the embodiment of the present invention mainly includes the following steps S101 to S104.

[0051] Step S101: transmitting a plurality of first electromagnetic wave signals to the clothes under test in the washing device.

[0052] In this embodiment, a plurality of first electromagnetic wave signals are emitted into the washing device through an electromagnetic wave signal device installed in the observation window of the washing device.

[0053] Step S102: receiving a plurality of second electromagnetic wave signals reflected from the plurality of first electromagnetic wave signals.

[0054] In this embodiment, the electromagnetic wave signal device receives multiple second electromagnetic wave signals which are reflected by the inner drum of the washing device after the multiple first electromagnetic wave signals pass through the tested clothes.

[0055] Step S103: determining a first signal attenuation rate based on the plurality of first electromagnetic wave signals and the plurality of second electromagnetic wave signals.

[0056] In this embodiment, the signal attenuation rate between each first electromagnetic wave signal and the second electromagnetic wave signal corresponding to the first electromagnetic wave signal is calculated, and then the first signal attenuation rate is calculated according to the multiple signal attenuation rates.

[0057] Step S104: determining the moisture content of the tested clothing based on the attenuation rate of the first signal.

[0058] Based on the above steps S101 to S104, the present invention obtains the signal attenuation rate between each first electromagnetic wave signal and the second electromagnetic wave signal corresponding to the first electromagnetic wave signal by transmitting multiple first electromagnetic wave signals and receiving multiple second electromagnetic wave signals reflected from the first electromagnetic wave signals, and obtains the first signal attenuation rate of the entire inner drum of the washing device based on the multiple signal attenuation rates, and then determines the moisture content of all clothes in the washing device based on the first signal attenuation rate. The moisture content of the clothes can be measured without contacting the clothes, and the coverage of the moisture content measurement of the clothes is improved by transmitting multiple signals, thereby improving the accuracy of the moisture content measurement.

[0059] The above steps S101 to S104 are further explained below.

[0060] For step S101, in one embodiment, the multiple first electromagnetic wave signals have the same signal strength; the transmitting of multiple first electromagnetic wave signals to the tested clothes in the washing device includes: transmitting multiple first electromagnetic wave signals with the same signal strength to the tested clothes in the washing device within a preset time period.

[0061] Specifically, the electromagnetic wave signal sensor may be a WIFI signal sensor, and the electromagnetic wave signal sensor may transmit multiple first electromagnetic wave signals simultaneously by the transmitting antenna of the electromagnetic wave signal sensor within a preset time period, or may transmit multiple first electromagnetic wave signals by the transmitting antenna of the electromagnetic wave signal sensor according to a preset time interval within a preset time period, and the multiple first electromagnetic wave signals transmitted have the same signal strength and different transmission directions. By transmitting multiple first electromagnetic wave signals in different directions, the signal can cover the entire inner drum of the washing device, thereby increasing the coverage of water content detection.

[0062] For step S102, in one embodiment, the multiple second electromagnetic wave signals have different signal strengths, and the signal strength of the second electromagnetic wave signal is less than the signal strength of the first electromagnetic wave signal; the receiving of the multiple second electromagnetic wave signals reflected by the multiple first electromagnetic wave signals includes: obtaining the multiple second electromagnetic wave signals reflected by the multiple first electromagnetic wave signals after passing through the tested clothing within a preset time period.

[0063] Specifically, the preset time period can be set to 5 seconds. At the beginning of the 5 seconds, the transmitting antenna of the electromagnetic wave signal sensor transmits multiple first electromagnetic wave signals, and within 5 seconds, the receiving antenna of the electromagnetic wave signal sensor receives the second electromagnetic wave signals that are reflected by the inner drum after the multiple first electromagnetic wave signals pass through the tested clothing.

[0064] The signal absorption rate of electromagnetic wave signals is small when they penetrate clothing, but when they penetrate water, they will be quickly absorbed by water. Therefore, the signal absorption rate of wet clothing varies according to the moisture content of the clothing. After passing through the tested clothing, multiple first electromagnetic wave signals will have multiple signal absorption rates due to the uneven moisture content of the clothing. These multiple signal absorption rates affect the strength of the second electromagnetic wave signal. Therefore, multiple first electromagnetic wave signals with the same signal strength will have different signal strengths after passing through clothing with different moisture contents. By receiving multiple second electromagnetic wave signals reflected by the inner drum after multiple first electromagnetic wave signals pass through the tested clothing, the signal attenuation of the entire inner drum can be known, thereby improving the accuracy of the subsequent determination of the moisture content of the clothing.

[0065] For step S103, in one embodiment, determining the first signal attenuation rate based on the multiple first electromagnetic wave signals and the multiple second electromagnetic wave signals includes: determining the second signal attenuation rate based on each of the first electromagnetic wave signals and the second electromagnetic wave signal corresponding to the first electromagnetic wave signal; calculating the average value of the multiple second signal attenuation rates; and determining the first signal attenuation rate based on the average value.

[0066] Specifically, the signal strength of each second electromagnetic wave signal is less than the signal strength of the first electromagnetic wave signal. To determine the second signal attenuation rate, the difference in signal strength is first calculated using the signal strength of each first electromagnetic wave signal and the signal strength of the corresponding second electromagnetic wave signal. The second signal attenuation rate is then determined based on the ratio of the difference in signal strength to the signal strength of the first electromagnetic wave signal. Finally, the average value of all the second signal attenuation rates obtained is calculated, and the average value is used as the first signal attenuation rate of all the tested clothes in the inner drum. By calculating the average value using multiple signal attenuation rates, the overall signal attenuation of all the clothes in the inner drum can be obtained, avoiding the deviation caused by measuring a single signal.

[0067] In one embodiment, before emitting multiple first electromagnetic wave signals to the tested clothes in the washing device, the method also includes: obtaining a third signal attenuation rate of the tested clothes before the washing device enters water; obtaining a clothing information correspondence relationship, wherein the clothing information correspondence relationship includes a correspondence relationship between clothing material information and clothing moisture content and a fourth signal attenuation rate; and determining clothing material information of the tested clothes based on the third signal attenuation rate and the clothing information correspondence relationship.

[0068] Specifically, before the washing device starts to take in water, multiple third electromagnetic wave signals are emitted into the washing device according to a preset time period, and multiple fourth electromagnetic wave signals reflected by the inner drum after the third electromagnetic wave signal passes through the tested clothing are received within the preset time period, and the fifth signal attenuation rate is calculated based on the third electromagnetic wave signal and the fourth electromagnetic wave signal corresponding to the third electromagnetic wave signal, and the third signal attenuation rate is determined according to the average value of the multiple fifth signal attenuation rates. At this time, because the washing device has not taken in water yet, the moisture content of the tested clothing is 0, and the third signal attenuation rate and the moisture content of the tested clothing are matched in the clothing information correspondence relationship to determine the clothing material information of the tested clothing. The clothing information correspondence relationship is the correspondence between clothing material information, moisture content, and fourth signal attenuation rate determined through offline experiments, wherein one clothing material includes multiple moisture contents, and one moisture content corresponds to one fourth signal attenuation rate. By determining the clothing material information of the tested clothing, the moisture content of the clothing can be more accurately analyzed according to the signal absorption of the clothing material.

[0069] With respect to step S104, in one embodiment, determining the moisture content of the tested clothing based on the attenuation rate of the first signal includes: obtaining clothing material information of the tested clothing; and determining the moisture content of the tested clothing based on the correspondence between the attenuation rate of the first signal, the clothing material information of the tested clothing, and the clothing information.

[0070] Specifically, the clothing information correspondence includes the correspondence between clothing material information and clothing moisture content and the fourth signal attenuation rate. Therefore, based on the clothing material information and the first signal attenuation rate of the tested clothing, the corresponding clothing material information, the fourth signal attenuation rate and the moisture content can be matched in the clothing information correspondence, and then the moisture content of the tested clothing is determined according to the matched moisture content. The moisture content of the clothing is determined based on the preset clothing correspondence and signal attenuation rate, and the moisture content measurement can be achieved without contacting the clothing. Matching according to the material information improves the accuracy of the clothing moisture content measurement, and further improves the user experience.

[0071] In one embodiment, the washing device includes an electromagnetic wave signal sensor, and the electromagnetic wave signal sensor is arranged on the observation window of the washing device; the transmitting of a plurality of first electromagnetic wave signals to the clothes under test in the washing device, and receiving a plurality of second electromagnetic wave signals based on the reflection of the plurality of first electromagnetic wave signals, comprises: the electromagnetic wave signal sensor transmits a first electromagnetic wave signal to the clothes under test in the washing device, and the electromagnetic wave signal sensor receives a second electromagnetic wave signal reflected by the first electromagnetic wave signal. The electromagnetic wave signal sensor is a WIFI signal sensor.

[0072] Specifically, the electromagnetic wave signal sensor in this embodiment can adopt a WIFI signal sensor, and the electromagnetic wave signal sensor can be installed on the observation window of the washing device. The washing device can be a washing machine, a dryer or a washer-dryer, which is not limited here; the electromagnetic wave signal sensor transmits a first electromagnetic wave signal with a frequency of 2.4GHz to the inner drum through a transmitting antenna, and receives a second electromagnetic wave signal based on the reflection of the first electromagnetic wave signal through a receiving antenna. Based on the characteristic that water can absorb electromagnetic waves, the first electromagnetic wave signal and the second electromagnetic wave signal based on the first electromagnetic wave signal penetrating the clothes and reflected by the metal inner drum are used to calculate and determine the signal attenuation rate, and the moisture content of the measured clothes in the inner drum of the washing device can be known based on the signal attenuation rate. The accuracy of measuring the moisture content using the signal attenuation rate is high, and there is no need to contact the clothes. The measurement speed is fast, and the measurement can be performed when the washing device is operating normally, saving time.

[0073] See attached Figure 2 , Figure 2 It is a complete step flow chart of a method for detecting moisture content of clothing according to an embodiment of the present invention.

[0074] like Figure 2 As shown, the clothing moisture content detection method of the present invention comprises the following steps:

[0075] Step S201: Start the program.

[0076] Step S202: before the washing device is filled with water, the third signal attenuation rate is obtained. In this embodiment, the third signal attenuation rate is the signal attenuation rate of the measured clothes before being immersed in water, by transmitting multiple third electromagnetic wave signals into the washing device, and receiving a fourth electromagnetic wave signal based on the reflection of the third electromagnetic wave signal, calculating the fifth signal attenuation rate of each third electromagnetic wave signal and the corresponding fourth electromagnetic wave signal, and taking the average of the multiple fifth signal attenuation rates as the third signal attenuation rate.

[0077] Step S203: Obtaining the corresponding relationship of clothing information. In this embodiment, the corresponding relationship of clothing information includes the corresponding relationship between clothing material information and clothing moisture content and the fourth signal attenuation rate.

[0078] Step S204: Determine the clothing material information of the tested clothing based on the third signal attenuation rate and the clothing information correspondence relationship. In this embodiment, before the washing device is filled with water, the moisture content of the tested clothing is 0. At this time, the clothing material information of the tested clothing can be determined in the clothing information correspondence relationship based on the third signal attenuation rate and the clothing moisture content.

[0079] Step S205: transmitting a plurality of first electromagnetic wave signals to the clothes under test in the washing device. In this embodiment, a plurality of first electromagnetic wave signals with the same signal strength and different transmission directions are transmitted to the clothes under test in the washing device through the WIFI signal sensor in a preset time period.

[0080] Step S206: receiving a plurality of second electromagnetic wave signals reflected from a plurality of first electromagnetic wave signals. In this embodiment, a second electromagnetic wave signal based on the first electromagnetic wave signal passing through the tested clothing and reflected from the metal inner drum of the washing device is received by the WIFI signal sensor within a preset time period, and the signal strength of the second electromagnetic wave signal is less than the signal strength of the first electromagnetic wave signal.

[0081] Step S207: Determine the first signal attenuation rate based on the multiple first electromagnetic wave signals and the multiple second electromagnetic wave signals. In this embodiment, the second signal attenuation rate is first calculated based on each first electromagnetic wave signal and the second electromagnetic wave signal corresponding to the first electromagnetic wave signal, and then the first signal attenuation rate is determined based on the average value of the multiple second signal attenuation rates.

[0082] Step S208: Obtaining clothing material information of the clothing being tested.

[0083] Step S209: Determine the moisture content of the tested clothing based on the first signal attenuation rate, the clothing material information of the tested clothing, and the clothing information correspondence. In this embodiment, the first signal attenuation rate and the clothing material information of the tested clothing are matched in the clothing information correspondence, and the moisture content corresponding to the matched clothing material information and the first signal attenuation rate is used as the moisture content of the tested clothing.

[0084] Step S210: End the program.
