[0002] Clothes processing equipment is an indispensable device in daily life. It can perform such processing as washing, dehydrating, drying, and caring for clothes, greatly improving the convenience of clothing processing. With the development of technology and the increase in user needs, the processing accuracy of clothes by clothing processing equipment has also improved. Taking washing machines as an example, current washing machines usually perform some detection actions before processing clothes, such as identifying the material of clothes, the entanglement of clothes, etc., so that clothes of different materials and entanglement can use different processing parameters, which helps to improve the processing effect of clothes.

[0003] However, the detection accuracy of current detection actions is often affected by many factors. In particular, the detection method using light is easily affected by the visible light shining into the processing tube, which reduces the detection accuracy. Summary of the invention

[0049] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0050] It should be understood that the "plurality" mentioned in this article refers to two or more. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B; "and / or" in this article is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in order to facilitate the clear description of the technical solutions of the embodiments of the present application, in the embodiments of the present application, the words "first", "second" and so on are used to distinguish between the same items or similar items with basically the same functions and effects. Those skilled in the art can understand that the words "first", "second" and so on do not limit the quantity and execution order, and the words "first", "second" and so on do not limit certain different

[0051] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus that includes a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or apparatus.

[0052] First, the terms involved in the embodiments of the present application are introduced.

[0053] Atomized glass: refers to glass with shading ability. The working principle is mainly based on electronic reaction and liquid crystal technology. The glass can be switched between transparent and opaque by controlling the electric current. This technology combines electronic reaction coating and liquid crystal molecules, so that the glass surface can form a uniform atomization effect, thereby achieving the functions of privacy protection and indoor space separation. When the current stimulates the coating, the internal liquid molecules will change instantly and form gas, causing the glass surface to have an atomization effect; when the current disappears, the liquid molecules quickly return to their original state, and the atomization effect disappears, achieving an effect that can be controlled at any time.

[0054] Clothes processing equipment is an indispensable device in daily life. It can perform such processing as washing, dehydrating, drying, and caring for clothes, greatly improving the convenience of clothing processing. With the development of technology and the increase in user needs, the processing accuracy of clothes by clothing processing equipment has also improved. Taking washing machines as an example, current washing machines usually perform some detection actions before processing clothes, such as identifying the material of clothes, the entanglement of clothes, etc., so that clothes of different materials and entanglement can use different processing parameters, which helps to improve the processing effect of clothes.

[0055] However, the detection accuracy of current detection actions is often affected by many factors. In particular, the detection method using light is easily affected by the visible light shining into the processing tube, which reduces the detection accuracy.

[0056] Based on this, the embodiment of the present application provides an observation window for a laundry treatment drum, referring to Figure 1-3 As shown, light outside the laundry processing drum enters the laundry processing drum through the observation window, and the observation window includes atomized glass;

[0057] The atomized glass can be controlled to switch between an atomized state and a transparent state, wherein when the atomized glass is in the atomized state, the intensity of light entering the laundry processing tub from outside the laundry processing tub is reduced.

[0058] Among them, the frosted glass in a transparent state means that the user can see the inside of the clothes processing drum through the frosted glass. If the inside of the clothes processing drum is dark, it can also be understood that the transparent state refers to the state when the frosted glass does not reduce the light intensity.

[0059] Correspondingly, the atomized state refers to the state in which the atomized glass reduces the light intensity. It should be noted that the degree of reduction of the light intensity is related to the structure of the atomized glass and the current passed, which is not specifically limited in this embodiment.

[0060] With this embodiment, the atomized glass includes two states, one is an atomized state and the other is a transparent state, so that when it is necessary to detect the clothes in the laundry treatment drum, the atomized glass can be controlled to switch to the atomized state. In the atomized state, since the light intensity in the laundry treatment drum is reduced, the influence of the light in the laundry treatment drum on the detection is reduced, thereby improving the detection accuracy. In addition, when it is not necessary to reduce the light intensity in the laundry treatment drum, the atomized glass can be controlled to switch to a transparent state, which is convenient for the user to observe the situation in the laundry treatment drum through the atomized glass, ensuring the user's use experience.

[0061] In a possible embodiment of the present application, the atomization state includes multiple atomization levels, and different atomization levels reduce the light intensity to different degrees.

[0062] In one embodiment, the number of atomization levels can be set according to the specific structural characteristics of the atomized glass. For example, if the atomized glass can only have three atomization programs through electrical control, three atomization levels can be set, among which level 3 is the highest and level 1 is the lowest.

[0063] In one embodiment, if a larger number of fogging levels are desired, multiple fogging glasses may be stacked. For example, two fogging glasses are stacked, namely the first glass and the second glass, and each fogging glass has three fogging levels. Therefore, when stacked, there are at least six fogging levels. Specifically, the first glass is slightly fogged and the second glass is transparent, corresponding to the fogging level 1, the first glass is moderately fogged and the second glass is transparent, corresponding to the fogging level 2, the first glass is highly fogged and the second glass is transparent, corresponding to the fogging level 3, the first glass is slightly fogged and the second glass is slightly fogged, corresponding to the fogging level 4, the first glass is slightly fogged and the second glass is moderately fogged, corresponding to the fogging level 5, and so on.

[0064] With this embodiment, there are multiple atomization levels corresponding to the atomization state, and different atomization levels can reduce the light intensity in the clothes processing drum to different degrees. When the atomized glass is switched to the atomized state, a suitable atomization level can be selected from multiple atomization levels, which improves the flexibility of the selection of the atomized glass shading situation.

[0065] Optionally, in an implementation of this embodiment, the atomized glass is controlled to switch from the transparent state to the atomized state and be at the corresponding atomization level when identifying the material of the clothes in the clothes processing drum.

[0066] In one embodiment, when the material of the clothing needs to be identified, the atomized glass is controlled to be in an atomized state, specifically, the highest atomization level.

[0067] With this implementation, when identifying the material of clothing, the atomized glass will be controlled to switch to an atomized state, so that the clothing material identification process is not easily affected by the light intensity in the clothing processing drum, thereby improving the accuracy of clothing material identification.

[0068] Optionally, in an implementation of this embodiment, the atomized glass includes a first surface facing the outside of the laundry processing tub and a second surface facing the inside of the laundry processing tub;

[0069] The observation window further comprises a light intensity detector, which is disposed on the second surface and is used to detect the light intensity of the light in the laundry processing tub.

[0070] With this implementation, since a light intensity detector capable of detecting the light intensity in the laundry processing drum is provided, it is convenient to obtain the light intensity in the laundry processing drum in real time, thereby facilitating adjustment of the atomization level according to the light intensity to improve detection accuracy.

[0071] Optionally, in an implementation of this embodiment, the observation window includes a mounting frame, the atomized glass is mounted in the mounting frame, and a current interface is provided on the mounting frame;

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

[0073] With this implementation, the mounting frame facilitates the installation and fixation of the atomized glass, and the current interface improves the convenience of power supply to the atomized glass.

[0074] This embodiment also provides a control method applied to the above observation window, such as Figure 4 As shown, the method includes:

[0075] S100. In response to an identification signal for material identification of clothes in a clothes processing drum, obtaining an identification result of light intensity in the clothes processing drum and / or the material of the clothes.

[0076] Among them, the identification signal refers to a signal triggered when the clothing material needs to be identified. This embodiment does not specifically limit the structure of the identification signal itself and the content it contains. It can actually be a timing signal or a control signal with a control function.

[0077] The recognition result is used to characterize the material of the recognized clothes. For example, the recognition result can be cotton, linen or fiber. When the recognition result is cotton, it proves that the material of the clothes in the clothes treatment drum is cotton. In addition, there are also cases where the material of the clothes cannot be recognized, that is, the recognition fails. In this case, the recognition result can be a null value or a character such as recognition failure, which is not specifically limited in this embodiment.

[0078] S102: Adjust the state of the frosted glass according to the light intensity and / or the recognition result, wherein the state includes a transparent state and frosted states with different frosting levels.

[0079] Different light intensities may correspond to different states of the fogged glass. Similarly, different recognition results may correspond to different states of the fogged glass. Therefore, after obtaining the light intensity and / or recognition result, the state of the fogged glass may be adjusted according to the light intensity and / or 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 recognized, and 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 content, 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 identification result, which helps to improve the accuracy of identification and the convenience for the user to observe the clothes in the laundry treatment drum.

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

[0083] Determine the 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] The state of the atomized glass is adjusted to the atomized state and the atomization level is the same as the atomization level corresponding to the light intensity interval in which the light intensity is located.

[0085] Specifically, the number of light intensity intervals may 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 one atomization level.

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

[0087] If the recognition result indicates that the material of the clothing cannot be determined, determining a target level according to a deviation between the clothing material parameter value that generates the recognition result and a preset clothing material interval;

[0088] The state of the frosted glass is adjusted according to the target level.

[0089] Among them, the recognition 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 recognition 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 into which the clothing material parameter value falls is cotton, then the recognition result is cotton. If the clothing material parameter value does not fall into any clothing material interval, a recognition result of recognition failure is generated. The result of recognition failure indicates that the material of the clothing cannot be determined. At this time, the target level will be determined according to the degree of deviation, and then the state of the atomized glass will be adjusted according to the target level.

[0090] In an optional implementation of the embodiment of the present application, determining the target level according to the deviation between the clothing material parameter value for generating the recognition result and the preset clothing material interval includes:

[0091] Determine the clothing material interval with the closest clothing material parameter value as the target interval;

[0092] taking the smaller 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 as the deviation value;

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

[0094] Among them, there are multiple preset clothing material intervals, and different clothing material intervals correspond to different materials; there are multiple preset deviation intervals, and different deviation intervals represent different deviation degrees, and 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 a light signal after diffuse reflection or transmission from the clothing.

[0096] According to a third aspect of the embodiments of the present application, a door body of a clothes processing device is provided, such as Figure 2 As shown, it includes the observation window mentioned above.

[0097] In an optional implementation of the embodiment of the present application, the door body further includes 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 respectively connected to the housing of the laundry processing device and one side of the mounting ring, and is used to realize the rotation of the mounting ring relative to the housing;

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

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

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

[0103] The memory is used to store computer programs;

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

[0105] According to a fifth aspect of an embodiment of the present application, there is provided a clothing processing device, comprising the above-mentioned observation window, the above-mentioned door body, the above-mentioned electronic device or adopting the above-mentioned control method.

[0106] In the above-mentioned embodiments of the present application, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments. The steps shown in the relevant flow chart can be executed in a computer system such as a set of computer executable instructions, and although the logical order is shown in the flow chart, in some cases, the steps shown or described can be executed in an order different from that here. In other words, the order of steps described in the foregoing embodiments is only an example, and it is also within the scope of protection of the embodiments of the present application to reasonably adjust the order of steps based on the content of the embodiments of the present application.

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

[0108] The ultraviolet sensor is installed inside the lifting rib in a flat manner. The function of the ultraviolet sensor is to detect the material of the clothes in the drum by using the working principle of diffuse reflection after flattening. The whole machine includes 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 contacts 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 includes an electro-atomizing glass 21, a door 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. Among them, the photosensitive sensor 24 detects the light intensity of the visible light from the outside world transmitted into the drum. In order to avoid the interference of ultraviolet light in the barrel, the preferred photosensitive sensor 24 adopts a visible light photosensitive sensor; the observation window is also equipped with an electro-atomizing function to adjust the blur degree of the observation window in stages. The electro-atomizing glass can be installed at any position between the observation window and the photosensitive sensor. It is preferably installed at the observation window, which can more conveniently perform electro-atomization and detect the light intensity entering from the outside.

[0109] Parameter Description:

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

[0111] Control method:

[0112] After putting clothes 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 of the clothes in the drum is detected as a (the average value after multiple collections). After conversion, it is first compared with the preset value of the main board to determine whether a is within the range set by △a. If it is within the range, the ultraviolet sensor on the lifting rib detects the material of the clothes normally. If the parameter a detected by the material is not within the range of △a, the visible light sensor will detect the light intensity β at this time to obtain the current light intensity β. Under the condition that the visible light has a certain influence on the ultraviolet light, the ultraviolet sensor will be used to detect the material of the clothes to detect whether the multiple collected parameters a (the average value after multiple collections) deviate from the preset value interval △a by ±10. If it is not within the deviation range of ±10, a will be compared with the preset value △a interval range again. If it is within the preset value interval range, the ultraviolet sensor in the lifting rib can detect the material of the clothes in the drum normally. If not, the main board will send a signal to the observation window to perform electro-atomization treatment on the glass of the observation window. The electro-atomization treatment is divided into 5 levels, from 1 to 5 from low to high. 1 is a lower blur and a lower degree of shading. 5 is the highest blur and the highest degree of shading, which can basically completely isolate the external light source. If the material detection parameter is within the deviation range of ±10, the observation window will be atomized according to the first level of electro-atomization. If the deviation is within the range of ±20, the observation window will be atomized according to the second level of electro-atomization. The highest level of atomization is the fifth level, which is complete atomization, and can basically completely isolate external light sources.

[0113] After each atomization, use the visible light sensor to measure the light intensity β after the visible light penetrates into the inner cylinder through the observation window after atomization. Each gear of the electric atomization corresponds to the light intensity β1-β5 after shading. β1-β2 The degree of atomization is light, which is suitable for the deviation range of the material identification parameter a and the closest preset interval △a within ±20. β3-β4 The degree of atomization is moderate, and the cylinder is basically in a dark state. At this time, the visible light has a low impact on the ultraviolet sensor. β5 is full atomization, which completely atomizes the observation window. It is suitable for detecting when the material identification parameter a is close to the interval of ±35 of polyester fiber. The detection range of this material is large and is greatly affected by visible light.

[0114] After adjusting to the corresponding atomization degree suitable for the UV sensor to detect the material at this time, the visible light detects the β light intensity to determine whether the shading effect after atomization is appropriate. The UV sensor begins to detect the clothes in the drum, collects them multiple times, and calculates the average value, which is compared with the preset value to distinguish what material it is.

[0115] For example, if the detection interval a is close to the △a interval of polyester fiber and close to the deviation of ±35 of the interval, the main board does not need to detect the light intensity at this time, because it is close to the polyester fiber material. At this time, it is determined that the electro-atomization step must be performed. The observation window is directly adjusted to the 5th gear. The visible light sensor detects and confirms that the intensity of the visible light in the drum is β5. The drum is in a state close to complete darkness. The main board controls the ultraviolet light work again to detect the material of the clothes in the drum.
