With the development of technology and the improvement of user demand, the treatment accuracy of laundry treatment apparatuses has also been improved. Taking a washing machine as an example, the current washing machine usually performs some detection actions before treating the laundry, such as identifying the material of the laundry and the entanglement of the laundry, so that different materials and entanglements of the laundry can adopt different treatment parameters, which helps to improve the treatment effect of the laundry.

[0049] In order to make the personnel in the technical field better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person of ordinary skill in the art without creative labor should belong to the scope of protection of the present application.

[0050] It should be understood that "multiple" mentioned herein refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " represents the meaning of or, for example, A / B can represent A or B; "and / or" herein only represents a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, in order to clearly describe the technical solutions of the embodiments of the present application, in the embodiments of the present application, "first", "second", etc. are used to distinguish the same items or similar items with basically the same function and effect. The person skilled in the art can understand that "first", "second", etc. do not limit the quantity and execution order, and "first", "second", etc. also do not limit that they must be different

[0051] In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device that includes a series of steps or units does not have to be limited to only those steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0052] First, the terms related to the embodiments of the present application are introduced.

[0053] Frosted glass: This refers to glass with light-blocking capabilities. Its working principle is primarily based on electronic reaction and liquid crystal technology, using controlled electric current to switch between transparent and opaque states. This technology combines an electronically reactive coating and liquid crystal molecules, allowing a uniform frosted effect to form on the glass surface, thus achieving privacy protection and interior space partitioning. When an electric current stimulates the coating, the internal liquid molecules undergo a momentary change, forming gas and creating the frosted effect on the glass surface; when the current disappears, the liquid molecules quickly return to their original state, and the frosted effect disappears, achieving a controllable effect at any time.

[0054] Clothing processing equipment is an indispensable part of daily life, capable of performing processes such as washing, dehydration, drying, and care for clothing, greatly improving the convenience of clothing handling. With technological advancements and increasing user demands, the precision of clothing processing equipment has also improved. Taking washing machines as an example, current washing machines typically perform detection actions before processing clothes, such as identifying the material and tangling status of the garments. This allows for the application of different processing parameters to clothes of different materials and with varying degrees of tangling, contributing to improved processing results.

[0055] The accuracy of current detection methods is often affected by a variety of factors, especially for light-based detection methods, which are easily affected by visible light shining into the processing tube, thus reducing the accuracy of the detection.

[0056] Based on this, embodiments of this application provide an observation window for a garment processing drum, referring to... Figures 1-3 As shown, outside light enters the garment processing drum through an observation window, which includes frosted glass.

[0057] The atomizing glass can be controlled to switch between an atomized state and a transparent state. When the atomized glass is in the atomized state, it reduces the light intensity of light entering the clothing processing drum from the outside.

[0058] In this context, "transparent" refers to the state where the user can see the inside of the garment processing drum through the frosted glass. If the inside of the garment processing drum is dark, it can also be understood as the state where the frosted glass does not reduce the light intensity.

[0059] Correspondingly, the atomized state refers to the state in which the atomizing glass reduces the light intensity. It should be noted that the degree of light intensity reduction is related to the structure of the atomizing glass and the current flowing through it, but this embodiment does not impose specific limitations on this.

[0060] According to the embodiment, the atomized glass includes two states, i.e., an atomized state and a transparent state, so that when it is necessary to detect the clothes in the clothes treatment cylinder, the atomized glass can be controlled to switch to the atomized state. In the atomized state, the light intensity in the clothes treatment cylinder is reduced, so that the influence of the light in the clothes treatment cylinder on detection is reduced, thereby improving the detection accuracy. In addition, when it is unnecessary to reduce the light intensity in the clothes treatment cylinder, the atomized glass can be controlled to switch to the transparent state, so that the user can observe the situation in the clothes treatment cylinder through the atomized glass, thereby ensuring the use experience of the user.

[0061] In a possible embodiment of the present application, the atomized state includes a plurality of atomized levels, and different atomized levels reduce the light intensity by different degrees.

[0062] In an embodiment, the number of atomized levels can be set according to the specific structural characteristics of the atomized glass. For example, the atomized glass can only appear three programs of atomization through electric control, and three atomized levels can be set, in which the third level is the highest and the first level is the lowest.

[0063] In an embodiment, if a large number of atomized levels are to be set, a plurality of atomized glasses can be stacked. For example, two atomized glasses, i.e., a first glass and a second glass, are stacked, and each atomized glass has three atomization degrees. Therefore, when the atomized glasses are stacked, at least six atomization degrees are provided. Specifically, the first glass is slightly atomized, and the second glass is transparent, corresponding to the first atomized level. The first glass is moderately atomized, and the second glass is transparent, corresponding to the second atomized level. The first glass is highly atomized, and the second glass is transparent, corresponding to the third atomized level. The first glass is slightly atomized, and the second glass is slightly atomized, corresponding to the fourth atomized level. The first glass is slightly atomized, and the second glass is moderately atomized, corresponding to the fifth atomized level. And so on.

[0064] According to the embodiment, the atomized state corresponds to a plurality of atomized levels, and different atomized levels can reduce the light intensity in the clothes treatment cylinder by different degrees. When the atomized glass is controlled to switch to the atomized state, a suitable atomized level can be selected from the plurality of atomized levels, thereby improving the selection flexibility of the light shielding condition of the atomized glass.

[0065] Optionally, in an implementation manner of the embodiment, the atomized glass is used to be controlled to switch from the transparent state to the atomized state and be in the corresponding atomized level when material identification is performed on the clothes in the clothes treatment cylinder.

[0066] In an embodiment, when material identification of the clothes is required, the atomized glass is controlled to be in the atomized state. Specifically, the atomized glass can be in the highest atomized level.

[0067] According to the implementation, the atomizing glass is switched to the atomizing state when the clothes are subjected to material identification, so that the clothes are less affected by the light intensity in the clothes treatment cylinder during the clothes material identification process, and the accuracy of the clothes material identification is improved.

[0068] Optionally, in an implementation of the embodiment, the atomizing glass comprises a first surface facing the outside of the clothes treatment cylinder and a second surface facing the inside of the clothes treatment cylinder.

[0069] The observation window further comprises a light intensity detector arranged on the second surface and configured to detect the light intensity of the light in the clothes treatment cylinder.

[0070] According to the implementation, the light intensity detector configured to detect the light intensity in the clothes treatment cylinder is arranged, so that the light intensity in the clothes treatment cylinder can be obtained in real time, and the detection accuracy can be improved by adjusting the atomizing level according to the light intensity.

[0071] Optionally, in an implementation of the embodiment, the observation window comprises a mounting frame, and the atomizing glass is mounted in the mounting frame, and the mounting frame is provided with a current interface.

[0072] The current input end of the current interface is configured to be connected with a wire for transmitting current, and the current output end of the current interface is connected with the current input end of the atomizing glass.

[0073] According to the implementation, the mounting frame facilitates the mounting and fixing of the atomizing glass, and the current interface improves the convenience of power supply of the atomizing glass.

[0074] The embodiment further provides a control method applied to the observation window, as shown in Figure 4 The method comprises the following steps.

[0075] S100, in response to an identification signal for identifying the material of the clothes in the clothes treatment cylinder, obtaining the light intensity in the clothes treatment cylinder and / or the identification result of the material of the clothes.

[0076] The identification signal refers to a signal triggered when the material of the clothes needs to be identified, and the structure and content of the identification signal are not limited in the embodiment. The identification signal can be a timing signal or a control signal with a control function.

[0077] The identification result is used to represent the material of the identified clothes. For example, the identification result can be cotton, hemp or fiber. When the identification result is cotton, it proves that the material of the clothes in the clothes treatment cylinder is cotton. In addition, there are cases where the material of the clothes cannot be identified, i.e. the identification fails. In this case, the identification result can be null or a character such as "identification failed", which is not limited in the embodiment.

[0078] S102, adjust the state of the atomized glass according to the light intensity and / or the recognition result, wherein the state includes a transparent state and atomized states of different atomization levels.

[0079] Different light intensities can correspond to different states of the atomized glass, and similarly, different recognition results can also correspond to different states of the atomized glass. Therefore, after obtaining the light intensity and / or the recognition result, the state of the atomized glass can be adjusted according to the light intensity and / or the recognition result.

[0080] Specifically, for example, if the recognition result indicates that the material of the clothes in the clothes treatment drum is cotton, it proves that the material of the clothes can be identified, and at this time, the state of the atomized glass can be kept unchanged or reduced by one atomization level. For another example, if the light intensity is large and greater than a preset threshold, the current state is increased by one atomization level.

[0081] Through the above, when the material of the clothes needs to be identified, the state of the atomized glass is adjusted according to the light intensity and / or the recognition result, which helps to improve the accuracy of identification and the convenience of users observing the clothes in the clothes treatment drum.

[0082] Optionally, in an implementation manner of the embodiment, adjusting the state of the atomized glass according to the light intensity includes:

[0083] determining a light intensity interval in which the light intensity is located, wherein a plurality of light intensity intervals are preset, and different light intensity intervals correspond to different atomization levels;

[0084] adjusting the state of the atomized glass to the atomized state and the atomization level corresponding to the light intensity interval in which the light intensity is located.

[0085] Specifically, the number of light intensity intervals can be determined according to the number of atomization levels, for example, the number of light intensity intervals is the same as the number of atomization levels, so that each light intensity interval corresponds to an atomization level.

[0086] In an optional implementation manner of the embodiment, adjusting the state of the atomized glass according to the recognition result includes:

[0087] if the recognition result indicates that the material of the clothes cannot be determined, determining a target level according to a deviation degree between a clothes material parameter value used to generate the recognition result and a preset clothes material interval;

[0088] adjusting the state of the atomized glass according to the target level.

[0089] The identification result is generated by the clothing material parameter value and the clothing material interval. Specifically, when the clothing material parameter value falls into a certain clothing material interval, the identification result of the clothing material corresponding to the clothing material interval is generated. For example, if the clothing material corresponding to the clothing material interval in which the clothing material parameter value falls is cotton, the identification result is cotton. If the clothing material parameter value does not fall into any clothing material interval, an identification failure result is generated. The identification failure result indicates that the clothing material cannot be determined, and the target level is determined according to the deviation degree, and then the state of the atomized glass is adjusted according to the target level.

[0090] In an optional implementation of the embodiment of the present application, the target level is determined according to the deviation degree between the clothing material parameter value used to generate the identification result and the preset clothing material interval, comprising:

[0091] The clothing material interval closest to the clothing material parameter value is determined as the target interval;

[0092] The smaller one of the absolute value of the difference between the clothing material parameter value and the upper limit value of the target interval and the absolute value of the difference between the clothing material parameter value and the lower limit value of the target interval is taken as the deviation value;

[0093] The atomization level corresponding to the deviation interval in which the deviation value is located is determined as the target level;

[0094] The clothing material interval is preset to have a plurality of clothing material intervals, and different clothing material intervals correspond to different materials. The deviation interval is preset to have a plurality of deviation intervals, and different deviation intervals represent different deviation degrees. Different deviation intervals correspond to different atomization levels.

[0095] In an optional implementation of the embodiment of the present application, the clothing material parameter value includes a value obtained by performing data conversion processing on the light signal after the clothing material occurs diffuse reflection or transmission.

[0096] According to the third aspect of the embodiment of the present application, a door body of a clothing treatment device is provided, as shown in the figure, comprising the observation window described above. Figure 2

[0097] In an optional implementation of the embodiment of the present application, the door body further comprises a mounting ring, a hinge assembly and a glass bowl.

[0098] The observation window is arranged on the mounting ring and corresponds to the ring hole of the mounting ring.

[0099] The hinge assembly is connected to one side of the mounting ring and the housing of the clothing treatment device, respectively, for realizing the rotation of the mounting ring relative to the housing. ​

[0100] The glass bowl is arranged on the mounting ring and opposite to the observation window, and when the door body is in the closed state, the glass bowl is located inside the shell, and the observation window is located outside the shell.

[0101] Preferably, the hinged assembly comprises a hinge fixing plate and a hinge.

[0102] According to a fourth aspect of the embodiments of the present application, an electronic device is provided, the electronic device comprising a memory and a processor;

[0103] The memory is configured to store a computer program.

[0104] The processor is configured to execute the computer program to implement the steps of the method.

[0105] According to a fifth aspect of the embodiments of the present application, a laundry processing device is provided, comprising the observation window, the door body, the electronic device or the control method described above.

[0106] In the above-described embodiments of the present application, the description of each embodiment has its own focus, and the parts not described in detail in a certain embodiment can be referred to the relevant description of other embodiments. The steps shown in the related flowcharts can be executed in a computer system such as a group of computer executable instructions, and although the logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here. In other words, the order of the steps described in the foregoing embodiments is only an example, and reasonable adjustment of the order of the steps based on the content of the embodiments of the present application is also within the protection scope of the embodiments of the present application.

[0107] In a specific implementation of an embodiment of the present application, material identification includes the following processing process:

[0108] The ultraviolet sensor is installed in the lifting rib in a flat manner, and the ultraviolet sensor is used for detecting the material of the clothes in the barrel through the working principle of diffuse reflection after being flat. The whole machine comprises a front shell 1, a door body 2 and a door lock 3, the door body 2 is rotatably arranged on the front shell 1, and the door body 2 is in contact with the door lock 3 when the door body 2 is closed, and the door lock 3 locks the door body 2. The door body 2 comprises an electric atomization glass 21, a door inner lining 22, a hinge fixing plate 23, a photosensitive sensor 24, a hinge assembly 25, a door inner shell 26, a lock hook 27, a rubber pad 28 and a glass bowl 29. The photosensitive sensor 24 detects the light intensity of the visible light transmitted into the barrel from the outside, in order to avoid the interference of the ultraviolet light in the barrel, the preferred photosensitive sensor 24 adopts a visible light photosensitive sensor; the observation window is also provided with an electric atomization function, which can adjust the fuzzy degree of the observation window in different positions, the electric atomization glass can be installed at any position between the observation window and the photosensitive sensor, and is preferably installed at the observation window, so that the electric atomization and the detection of the light intensity entering from the outside can be more convenient.

[0109] Parameter description:

[0110] The ultraviolet spectrum wavelength used in the patent proposal is 10-400nm, and the wavelength absorbed is calculated according to the quantum theory as △E=hv=hc / λ. The visible light spectrum wavelength is 400-760nm, so when detecting the light intensity of the visible light projected into the barrel from the outside, the barrel will not be disturbed by the ultraviolet light in the barrel.

[0111] Control method:

[0112] After the clothes are put into the drum, the main control board detects the current and power of the driving motor to determine the weight of the clothes in the drum. After determining that there are clothes in the drum, the ultraviolet sensor on the lifting rib starts to detect the material of the clothes in the drum. Through diffuse reflection, the corresponding material parameter a (average value after multiple acquisitions) of the clothes in the drum is detected. After conversion, it is compared with the preset value of the main board first to determine whether a is within the interval range of △a. If it is within the interval range, the ultraviolet sensor on the lifting rib can normally detect the material of the clothes. If the material detection parameter a is not within the range of △a, the visible light sensor detects the light intensity β at this time, and the current light intensity β is obtained. Under the condition that visible light has a certain influence on ultraviolet light, the ultraviolet sensor is used again to detect the material of the clothes. It is determined whether the multiple acquisition parameters a (average value after multiple acquisitions) at this time deviate from the preset value interval △a by ±10. If it is not within the deviation range of ±10, a is compared with the preset value interval △a again. If it is within the interval range of the preset value, the ultraviolet sensor in the lifting rib can normally detect the material of the clothes in the drum. If not, the main board sends a signal to the observation window to perform electro-fogging treatment on the glass of the observation window. The electro-fogging treatment is divided into five levels, from low to high, 1 to 5. The 1st level has a lower degree of obscuration, and the 5th level has the highest degree of obscuration, which can basically completely isolate external light sources. If the material detection parameter is within the deviation range of ±10, the observation window is fogged according to the electro-fogging degree of the 1st level. If the deviation is within the range of ±20, the observation window is fogged according to the electro-fogging degree of the 2nd level. The highest fogging degree is the 5th level, which is complete fogging and can basically completely isolate external light sources.

[0113] After each fogging, the visible light sensor is used to detect the light intensity β of the observation window after the visible light penetrates into the inner drum after fogging. Each level of electro-fogging corresponds to the light intensity β1-β5 after shading. The fogging degree of β1-β2 is light, which is suitable for the material identification parameter a deviating from the closest preset interval △a by ±20. The fogging degree of β3-β4 is moderate, and the inner drum is basically in a dark state. At this time, the influence of visible light on the ultraviolet sensor is low. β5 is full fogging, which completely fogs the observation window and is suitable for detecting the material identification parameter a close to the polyester fiber interval ±35. The detection interval of this material is large and is greatly affected by visible light.

[0114] After adjusting to the corresponding fogging degree suitable for the ultraviolet sensor to detect the material at this time, the visible light detects the light intensity β to determine whether the shading effect after fogging is appropriate. The ultraviolet sensor starts to detect the clothes in the drum, acquires multiple times, calculates the average value, compares it with the preset value, and determines the material.

[0115] For example, if the detection interval a is close to the polyester fiber material interval, and the deviation is close to the interval of ±35, the mainboard does not need to detect the light intensity at this time, because it is close to the polyester fiber material, and it is determined that the step of electric atomization must be carried out, and the observation window is directly adjusted to the fifth gear. The visible light sensor detects the light intensity of the visible light in the cylinder as β5, and the cylinder is in a state close to complete darkness. The mainboard controls the ultraviolet light working on the detection material of the clothes in the cylinder again at this time. The detection value at this time should be in the preset interval of the polyester fiber material.
