In the absence of further limitations, an element defined by the phrase "comprises a..." does not exclude the presence of other identical elements in the product or system comprising the element.

[0043] In order to solve the problem of high efficiency and energy saving of existing clothes processing equipment with sterilization and disinfection functions, the embodiment of the present invention provides a control method for clothes processing equipment, combining Figures 4a-4d The clothing processing device includes a body 5, a clothing processing drum, a door body 3, a door seal and a light wave sterilization device; the clothing processing drum is installed in the body 5; the body is provided with an opening connected to the clothing processing drum; the door body 3 is used to cover the opening; the door seal is provided in the opening, and is used to seal the door body 3 and the clothing processing drum; the light wave sterilization device is provided on the door body 3 and / or the door seal, and the light wave sterilization device includes a first light wave band 13, and the first light wave band 13 can generate ultraviolet light waves and / or infrared light waves in broadband light waves. Ultraviolet light waves can be used to sterilize clothing. Ultraviolet light waves are generally divided into UVA (315nm-400nm), UVB (280nm-315nm), and UVC (200nm-280nm). In this embodiment, the UVC band is preferred, and the UVC band can effectively sterilize clothing. In addition, infrared light waves generate a large amount of heat energy, which can not only kill bacteria, but also assist in heating the washing process.

[0044] The control method of the clothes processing device according to the embodiment of the present invention will be described below with reference to the accompanying drawings.

[0045] Figure 1 FIG. 1 is a flow chart of a control method for a clothes processing device according to an embodiment of the present invention. Figure 1 , control methods include:

[0046] S100, in the washing and heating stage, the light waves generated when the first light wave band is turned on are used to sterilize and auxiliary heat the clothes, so that the water temperature reaches the first set temperature.

[0047] Specifically, the washing phase of the laundry treatment device includes a washing and heating phase, which is used to heat the wash water to a first set temperature. During this phase, the ultraviolet (UVC) sterilization generated by the first light band and the photothermal effect of the infrared light band are used for multiple sterilization, improving the efficiency of killing bacteria and viruses. The infrared light band also assists in heating the wash water, speeding up the washing process, improving the washing effect, and reducing laundry energy consumption.

[0048] Further optionally, the light wave sterilization device is arranged on the top of the door seal, the clothes processing drum includes an outer drum and an inner drum, and a heating device is arranged at the bottom of the outer drum. Figure 2 In S100, the light waves generated when the first light wave band is turned on are used to sterilize and auxiliary heat the clothes, including:

[0049] S102, after the water intake is completed, determining whether the water temperature is less than or equal to the second set water temperature; if so, executing S104;

[0050] S104, turning on the first light band;

[0051] S106, controlling the heating device to heat the washing water and controlling the inner drum to agitate the washing water;

[0052] The second set water temperature is lower than the first set water temperature.

[0053] When the washing machine enters the wash cycle and water is fully ingested, the inlet water temperature is first detected and compared to a preset water temperature threshold. If the water temperature is ≤ the second set water temperature, the inlet water temperature is too low, possibly due to low ambient temperature or the inlet pipe being in a low-temperature environment. This low water temperature is not conducive to stain removal and detergent dissolution, so the second light band 13 needs to be activated for auxiliary heating. The original heating device (such as a heating pipe) of the clothing processing equipment is located at the bottom of the outer and inner drums. During washing and heating, the wash water in the drum is not sufficiently agitated, which can easily lead to uneven water temperature, resulting in high water temperature at the bottom and low water temperature at the top, resulting in a lower water temperature at the clothes in the inner drum. In this embodiment, the first light band 13 is preferably located at the top of the door seal. The broadband light waves it generates can directly irradiate the clothes, directly heating them and effectively raising the wash water temperature. When the first light band 13 is activated, the heating pipe is activated to heat the wash water in areas of the drum bottom that are not exposed to the light waves, while simultaneously causing the inner drum to agitate the wash water to reach the first set water temperature. Among them, the rhythm of stirring the washing water in the inner drum needs to be slower, preferably at a speed of 50rpm / min, with a run-stop ratio of: forward 25s, stop 5s, reverse 25s, stop 5s, so as to achieve uniform water temperature.

[0054] Further optionally, a reflective structure is provided on the inner wall of the inner drum of the clothing processing drum, and the reflective structure includes light surface protrusions formed on the inner drum that cause multi-point refraction of light waves, an uneven rough curved surface formed by water-permeable holes opened on the inner drum, and / or a reflective coating applied to the inner wall of the inner drum to reflect light waves.

[0055] To address the problem of clothing blocking light and reducing sterilization efficiency, the present invention incorporates a reflective coating 15 on the inner drum wall, enhancing the metal drum wall's reflective effect. This allows light waves striking the drum wall to be evenly and efficiently reflected onto the clothing. Furthermore, polished protrusions 14 on the drum wall scatter light striking the protrusions, increasing the light's irradiation range. The polished protrusions 14 and permeable holes 16 form a rough, uneven surface, causing diffuse reflection when light strikes the drum wall. This increases the light's coverage and allows the light to fully cover the clothing in the drum, enhancing the sterilization effect. The spherical protrusions on the drum wall both assist in cleaning clothing and scatter light striking the protrusions, ensuring the drum is always surrounded by a diffusely reflected light wave circle, irradiating the clothing in all directions and improving the sterilization effect.

[0056] It is worth noting that the first light wave band 13 is set on the top of the door seal, preferably on the original downlight of the clothing processing equipment, directly irradiating the clothes, and cooperating with the diffuse reflection coating on the wall of the drum to directly heat the clothes, quickly and effectively increasing the washing water temperature.

[0057] Further optional, combined Figure 2 When the water temperature is greater than the second set water temperature, the control method further includes:

[0058] S108, controlling the heating device to heat the washing water.

[0059] If the water temperature reaches the second set water temperature, the original heating device can be used to heat the washing water directly. This can ensure the heating effect and reduce energy consumption.

[0060] Further optionally, after the water temperature reaches the first set temperature, the control method further includes:

[0061] S110, turning off the first light band;

[0062] S112, controlling the heating device to intermittently heat the washing water.

[0063] When the first light band 13 is turned on and the heating tube is turned on, the water temperature is detected at the same time until the washing water temperature reaches the main wash temperature set by the program, that is, the first set temperature. Then the second light band 13 is turned off and only the heating tube is turned on and off intermittently to maintain the water temperature in the drum, so that the clothes are always at the optimal washing water temperature.

[0064] Further optional, combined Figure 1 、 2 , the control method further includes:

[0065] S200 , when controlling the inner drum of the laundry treatment drum to loosen the laundry in the drum, turning on the first light wave band to sterilize the laundry.

[0066] Further optionally, the clothes processing device is provided with a clothes loosening process, and the clothes loosening process is arranged in: the washing stage, before filling water into the clothes processing drum, and / or after dehydration is completed, and / or in the drying stage.

[0067] For example, after the main wash is completed, rinsing and dehydration continue. After dehydration is complete, the clothes enter the loosening process to shake the clothes loose. When the clothes are loose, the first light band 13 is turned on to sterilize the washed clothes to prevent bacterial growth. At the same time, the first light band 13 irradiates the door seal, evaporating moisture in the door seal seam and drying the door seal, which is very prone to bacterial growth in humid environments, to ensure a healthy and clean environment inside the drum until the washing process is finally completed.

[0068] Optionally, the light wave sterilization device further includes a second light wave band 12, which can generate visible light waves in the broadband light wave. Figure 3 , control methods include:

[0069] S300, during the laundry processing process, determining whether the laundry processing device needs to turn on a light;

[0070] S302, when the clothes processing device has a light-on demand, turning on the second light band;

[0071] The clothing processing process includes washing process, drying process and care process.

[0072] Combine Figure 4b 、 4c In an embodiment of the present invention, a double-layer light band is provided on the original downlight of the clothing processing device to form a light wave lamp 7. The light wave lamp 7 includes a light wave lamp connection port 8, a light wave lamp conduit 9, a limit block 10, a slot 11, a first light wave band 13, and a second light wave band 12. The slot is used to assemble the light wave lamp to the door seal, and the limit block is used to limit the rotation of the light wave lamp. Both structures are installation and assembly structures and have different forms. The first light wave band 13 is the ultraviolet C band and infrared band of the broadband light wave. The UVC band ultraviolet light wave can be used to sterilize clothes, and the infrared light wave generates a large amount of heat energy that can kill bacteria and also assist in heating during the washing process. The second light wave band 12 is the visible light band of the broadband light wave, which is used to realize the lighting of the inner drum of the washing machine. The light wave sterilization device of this light wave band is stable and has low power, which can realize the lighting function and reduce energy consumption. This embodiment uses the integrated setting of the double-layer light wave band and is matched with reasonable washing control logic to achieve a simple structure, diverse functions, and reduce energy consumption.

[0073] During the laundry processing process, if the laundry processing device detects that it needs internal lighting, the lighting condition is met and the first light band 13 is turned on until the operation ends. The laundry processing process includes the washing process, the drying process, and the care process. The care process is mainly used to sterilize clothes and remove wrinkles.

[0074] Further optionally, the clothes processing device is provided with a display screen 2, and determining whether there is a need to turn on a light of the clothes processing device in S300 includes:

[0075] When responding to a light-on instruction or sensing that the display screen of the clothes processing device is touched, it is regarded that there is a need to turn on the light of the clothes processing device.

[0076] During the laundry processing phase, if a light-on instruction is received or the display screen is sensed to be touched, it is considered that the user has a light-on requirement, and the second light band 12 is turned on. Figure 3 When a user needs to wash clothes, the machine turns on the second light band 12, which illuminates the tub using visible light to facilitate the user's access to laundry. The second light band 12 is set to automatically turn off after a certain period of inactivity, saving electricity. After the user inserts the laundry, the washing, drying, and care processes of the program begin. During the washing process, if the user detects that the tub requires lighting, the lighting condition is met, and the second light band 12 is turned on until the cycle ends. The second light band 12 is then turned on again to illuminate the tub, making it easier for the user to remove the laundry, until the machine shuts down.

[0077] Optionally, the control method further includes simultaneously activating the first light band 13 and the second light band 12. For example, if the first light band 13 is activated during the washing and heating phase, the second light band 12 is activated upon receiving a light-on command or sensing a touch on the display screen. Alternatively, if the second light band 12 is activated during the loosening phase of clothing upon receiving a light-on command or sensing a touch on the display screen, the second light band 12 is activated. This utilizes UVC sterilization and the photothermal effects of visible and infrared light bands for multiple sterilization efforts, improving bacterial and viral killing efficiency. Visible light also provides an intuitive sterilization experience, reminiscent of the natural sterilization effects of sunlight, leaving clothing with a sunny scent.

[0078] An embodiment of the present invention also provides a control device, which includes one or more processors and a non-temporary computer-readable storage medium storing program instructions. When the one or more processors execute the program instructions, the one or more processors are used to implement the method according to any one of the first aspects.

[0079] An embodiment of the present invention also provides a clothing processing device, which includes a machine body, a clothing processing drum, a door body, a door seal and a light wave sterilization device; the clothing processing drum is installed in the machine body; the machine body has an opening connected to the clothing processing drum; the door body is used to cover the opening; the door seal is arranged in the opening, for sealing the door body and the clothing processing drum; the light wave sterilization device is arranged on the door body and / or the door seal, the light wave sterilization device includes a first light wave band and a second light wave band, the first light wave band can generate ultraviolet light waves and infrared light waves in broadband light waves, and the second light wave band can generate visible light waves in broadband light waves, and it adopts any one of the control methods of the first aspect, or includes the control device of the second aspect.

[0080] Further optionally, the light wave sterilization device is arranged on the top of the door seal, and a reflective structure is provided on the inner wall of the inner drum of the clothing processing drum. The reflective structure includes light surface protrusions formed on the inner drum that cause multi-point refraction of light waves and an uneven rough curved surface formed by water-permeable holes opened on the inner drum and / or a reflective coating applied to the inner wall of the inner drum to reflect light waves.

[0081] In addition, multi-segment broadband light waves are used for sterilization, heating and lighting. The light wave band is installed in the original downlight position of the washing machine, and the visible light segment of the light wave is used instead of the downlight for lighting. This can not only meet the original lighting needs, but also sterilize and assist in heating the clothes without adding additional structural parts costs. It is highly efficient and the cost is extremely low.

[0082] In different embodiments provided by the present invention, the same parameters, nouns, logic, etc. should be understood as having a unified meaning, and this application does not intentionally repeat the description in each embodiment.

[0083] The exemplary embodiments of the present disclosure are specifically shown and described above.
