Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] Most existing drum washing machines do not have the function of detecting the material of the clothes inside the drum. Even those washing machines that do have this function mainly use a camera inside the drum to first capture images of the clothes inside and then analyze the material based on these images. However, this method suffers from incomplete images and a narrow detection range because the camera's position is fixed, the shooting distance cannot be adjusted, and the images cannot be taken from all angles.

[0053] This invention creatively provides a garment processing device with the function of detecting garment material. The emitting electrode is set on the observation window, and the receiving electrode is set on the support frame of the inner tube. The emitting electrode emits light signals, and the receiving electrode can receive light signals. The material of the inner tube garment can be accurately determined according to the intensity of the light signal emitted by the emitting electrode and the intensity of the light signal received by the receiving electrode, with a large detection range.

[0074] Example 2

[0075] This embodiment proposes a method for detecting clothing material in a clothing processing device, wherein the clothing processing device is any of the above-mentioned clothing processing devices with clothing material detection functions; when the clothing processing device is running a washing program, the clothing material detection method includes:

[0076] S1. Obtain the intensity λ1 of the optical signal generated by the emitter 25 and the intensity λ2 of the optical signal received by the receiver 35;

[0077] S2. Determine the material of the inner garment 13 based on the strengths λ1 and λ2.

[0078] S2 includes:

[0079] S21. Calculate the difference Δλ between the intensities λ1 and λ2;

[0080] S22. Compare Δλ with the preset values ​​of each material one by one, or compare Δλ with the threshold values ​​of each preset range of each material one by one.

[0081] S23. When Δλ equals one of the material preset values ​​or one of the material preset ranges, determine that the material of the inner garment 13 is the material corresponding to one of the material preset values ​​or one of the material preset ranges.

[0082] It improves the accuracy of clothing material detection, has a large detection range, is convenient to power, reduces the influence of air temperature inside the inner drum on clothing material detection, and makes clothing material detection stable. It solves the problems of inaccurate clothing material detection, narrow detection range, and inconvenient power supply of cameras in existing technologies. It also solves the problem of inaccurate clothing material detection and low detection accuracy caused by the large influence of air temperature inside the inner drum when using near-infrared spectroscopy recognition in existing technologies.

[0083] It should be noted that light signals can be transmitted when they come into contact with clothing. When light signals are transmitted after contact with clothing, transmission parameter values ​​can be obtained.

[0084] Specifically, the transmission parameter value can be the parameter value of the transmitted light signal itself after transmission, such as the transmittance and light intensity of the transmitted light signal, or it can be the parameter value obtained by calculating the parameter value of the transmitted light signal itself, such as substituting the transmittance and / or light intensity of the transmitted light signal into a preset calculation formula to obtain the transmission parameter value; in general, as long as different clothing materials can correspond to different transmission parameter values.

[0085] In one embodiment, the preset calculation formula for calculating the transmission parameter value can be a formula that includes the wavelength and intensity of the transmitted light signal. For example, the transmission parameter value b = T% * φ luminous flux * power factor (intensity-related), and the transmittance T% = I (light intensity after transmission reduction) / IO (original light intensity) * 100%.

[0086] In one embodiment, in order to determine the material of the clothing, a transmission standard value range is preset. Different transmission standard value ranges correspond to different clothing materials. In other words, there is a correspondence between the transmission standard value range and the clothing material.

[0087] Specifically, the transmission standard value range is a numerical range composed of transmission standard values. It's important to note that transmission standard values ​​and transmission parameter values ​​are of the same type or obtained using the same algorithm. The difference lies in that transmission standard values ​​are obtained by conducting transmission experiments on clothing with known material properties, while transmission parameter values ​​are obtained by conducting transmission experiments on clothing during actual material identification. For ease of understanding, for example, during testing, formula B is used to calculate the transmittance and intensity of the transmitted light signal to obtain the transmission standard value. After multiple tests on clothing of material b, a numerical range Q1 can be defined based on all the obtained transmission standard values. In actual clothing material identification, formula B is also used to calculate the transmittance and intensity of the transmitted light signal to obtain the transmission parameter value. Since the calculation process for the transmission parameter value is the same as that for the transmission standard value, the clothing material can be determined based on the transmission parameter value.

[0088] The correspondence between transmission standard value ranges and clothing materials is as follows: each type of clothing material corresponds to a transmission standard value range, and different types of clothing materials correspond to different transmission standard value ranges. For example, material 'a' corresponds to the transmission standard value range Q1, which is the correspondence. This ensures that when the transmission parameter value is within Q1, the clothing material can be determined to be 'a'. Preferably, the correspondence obtained using an ultraviolet sensor includes: 10-13 corresponds to cotton, 13.5-15.5 corresponds to linen, 19-23 corresponds to wool, 16.5-18.9 corresponds to silk, 29-33 corresponds to polyester fiber, and 33.5-39 corresponds to synthetic fiber.
