[0032] In related technologies, the water electrolysis module is installed on the water inlet pipe of the clothing processing equipment, which prevents the water electrolysis module from being in sufficient contact with water for a long time, resulting in a mediocre effect in generating hydroxyl radicals.
[0033] An embodiment of the first aspect of this application provides an outer tub assembly for use in clothing handling equipment (such as washing machines, washer-dryer combos, etc.). Please refer to... Figures 1 to 3 The outer barrel assembly 100 includes an outer barrel 10, a protective cover 30, and an electrolyzed water module 20. The protective cover 30 is connected to the barrel wall of the outer barrel 10 and protrudes along the direction of the outer wall of the outer barrel 10 toward the inner wall of the outer barrel 10. The protective cover 30 has a water passage hole 31 that connects the inside and outside of the outer barrel 10. The electrolyzed water module 20 is installed on the outside of the outer barrel 10, and at least a portion of the electrolyzed water module 20 is inside the protective cover 30.
[0034] Understandably, the axial direction of the outer tub 10 can be horizontal or nearly horizontal, meaning the outer tub assembly 100 is used in a drum-type garment handling device, such as a drum washing machine. Of course, the axial direction of the outer tub 10 can also be vertical or nearly vertical, meaning the outer tub assembly 100 is used in a pulsator-type garment handling device, such as a pulsator washing machine.
[0035] Understandably, when the axial direction of the outer barrel 10 is horizontal or nearly horizontal, the protective cover 30 can be connected to the lower end of either end of the outer barrel 10, meaning the water electrolysis module 20 is located at the lower end of either end of the outer barrel 10; or, the protective cover 30 can also be connected to the bottom of the outer barrel 10, meaning the water electrolysis module 20 is located at the bottom of the outer barrel 10. When the axial direction of the outer barrel 10 is vertical or nearly vertical, the protective cover 30 can be connected to the lower end of the outer barrel 10, meaning the water electrolysis module 20 is located at the lower end of the outer barrel 10; or, the protective cover 30 can also be connected to the lower side of the outer barrel 10, meaning the water electrolysis module 20 is located at the lower side of the outer barrel 10.
[0036] The protective cover 30 is used to protect the water electrolysis module 20 in order to extend the service life of the water electrolysis module 20.
[0037] The protective cover 30 is connected to the wall of the outer barrel 10. It can be understood that the protective cover 30 can be integrally formed into the wall of the outer barrel 10, or it can be separately fixedly connected to the wall of the outer barrel 10. The protective cover 30 protrudes along the direction of the outer wall of the outer barrel 10 towards the inner wall of the outer barrel 10, which can be understood as the protective cover 30 being located inside the outer barrel 10.
[0038] The protective cover 30 has a water passage hole 31 that connects the inside and outside of the outer tub 10. In this way, water inside the outer tub 10 can enter the protective cover 30 through the water passage hole 31, so that the electrolyzed water module 20 inside the protective cover 30 can be in full contact with water for a long time, which is conducive to the generation of hydroxyl free radicals, thereby improving the sterilization, disinfection and deep cleaning effect of clothing.
[0039] The number of water passage holes 31 is multiple. Understandably, the water passage holes 31 can be provided at the end of the protective cover 30, or at the side of the protective cover 30, or some of the water passage holes 31 can be provided at the end of the protective cover 30 and some of the water passage holes 31 can be provided at the side of the protective cover 30.
[0040] The shape of the protective cover 30 is not limited in this application. For example, the protective cover 30 can be cylindrical, frustum-shaped, prism-shaped, etc.
[0041] The shape of the water passage 31 is not limited in this application. For example, the shape of the water passage 31 can be circular, elliptical, oval, polygonal, elongated, or irregular.
[0042] The protective cover 30 has an opening facing the outside of the outer tank 10. The water electrolysis module 20 is installed on the outside of the outer tank 10, and part of the water electrolysis module 20 is inserted into the protective cover 30 through the opening. Of course, the water electrolysis module 20 can also be completely inserted into the protective cover 30.
[0043] The water electrolysis module 20 is a device capable of generating hydroxyl radicals. Its principle is to create an electric field by applying voltage to the electrode plates, causing the aqueous solution to ionize and generate hydroxyl radicals. These hydroxyl radicals have strong oxidizing properties, capable of killing bacteria and decomposing organic matter in water, thereby achieving sterilization, disinfection, and deep cleaning of clothing.
[0044] The beneficial effects of the outer tub assembly 100 provided in this application embodiment are as follows: At least a portion of the water electrolysis module 20 of the outer tub assembly 100 provided in this application embodiment is located inside the protective cover 30, allowing the water electrolysis module 20 to be in prolonged and sufficient contact with the water inside the outer tub 10 through the water passage 31 on the protective cover 30. This is beneficial for the generation of hydroxyl free radicals, thereby improving the sterilization, disinfection, and deep cleaning effects on clothing. The water electrolysis module 20 is installed on the outside of the outer tub 10, separating it from the heater 40 inside the outer tub 10. When the water electrolysis module 20 needs to be replaced, it can be easily removed, making disassembly convenient and reducing operating costs.
[0045] Please refer to Figure 3 In some embodiments, a sealing ring 24 is provided between the water electrolysis module 20 and the outer tank 10 to ensure sealing performance.
[0046] In some embodiments, the sealing ring 24 is disposed between the water electrolysis module 20 and the front tank 11.
[0047] In some embodiments, the sealing ring 24 is a rubber sealing ring.
[0048] In some embodiments, the outer tank 10 is provided with a first annular step, and the water electrolysis module 20 is provided with a second annular step; wherein the first annular step and the second annular step are arranged opposite to each other, and the sealing ring 24 is located between the first annular step and the second annular step to further improve the sealing performance.
[0049] Please refer to Figure 4 and Figure 5 In some embodiments, the protective cover 30 is integrally formed on the barrel wall of the outer barrel 10, that is, the protective cover 30 and the outer barrel 10 are integrally formed as a single structure.
[0050] In some embodiments, the protective cover 30 is disposed on the front barrel 11, and the protective cover 30 and the front barrel 11 are integrally formed. Of course, the protective cover 30 can also be disposed on the rear barrel 12, which can be understood as the protective cover 30 and the rear barrel 12 being integrally formed.
[0051] Based on the above technical solution, since the protective cover 30 is integrally formed on the wall of the outer tub 10, it can prevent the protective cover 30 from falling off the outer tub 10 during the operation of the clothing processing equipment, thus preventing abnormal noise from the equipment.
[0052] In other embodiments, the protective cover 30 and the outer barrel 10 can be separate structures, that is, the protective cover 30 is separately fixedly connected to the inner wall or outer wall of the outer barrel 10. For example, the protective cover 30 can be fixed to the inner wall or outer wall of the outer barrel 10 by means of snap-fit, fastener connection, riveting, etc.
[0053] Please refer to Figure 4 and Figure 5 In some embodiments, the bottom of the outer barrel 10 is provided with a cavity 111, and the protective cover 30 is located in the cavity 111.
[0054] Understandably, the protective cover 30 can be connected to the bottom wall of the cavity 111; or, the protective cover 30 can be connected to the side wall of the cavity 111.
[0055] In some embodiments, the protective cover 30 may be connected to the barrel wall at the end of the outer barrel 10, for example, the protective cover 30 may be connected to the barrel wall at the end of the front barrel 11, or the protective cover 30 may be connected to the barrel wall at the end of the rear barrel 12.
[0056] In some embodiments, the protective cover 30 is completely within the recess 111 to maintain a safe distance between the protective cover 30 and the inner tub, thus preventing interference between the protective cover 30 and the inner tub. Of course, while ensuring that the protective cover 30 does not interfere with the inner tub, the protective cover 30 may also protrude slightly from the recess 111.
[0057] In some embodiments, a drain outlet 113 is provided in the cavity 111, and the protective cover 30 is located obliquely above the drain outlet 113.
[0058] Please refer to Figure 3 and Figure 5 In some embodiments, the water passage 31 includes a first water passage 311 located at the end of the protective cover 30.
[0059] Understandably, multiple first water passage holes 311 are provided at the end of the protective cover 30. The multiple first water passage holes 311 can be evenly arranged at the end of the protective cover 30 to ensure the uniformity of water flow.
[0060] Understandably, the shapes of the multiple first water passage holes 311 can be the same or different. When the multiple first water passage holes 311 have the same shape, the shape of the first water passage hole 311 can be circular, elliptical, polygonal, or elongated, etc. When the multiple first water passage holes 311 have different shapes, the shape of the first water passage hole 311 can be at least two of the following: circular, elliptical, polygonal, and elongated. For example, some of the multiple first water passage holes 311 may be circular and some may be elliptical.
[0061] Please refer to Figure 3 and Figure 5 In some embodiments, the water passage 31 includes a second water passage 312 disposed on the side of the protective cover 30.
[0062] Understandably, multiple second water passage holes 312 are provided along the circumference of the protective cover 30. Among them, the multiple second water passage holes 312 can be evenly arranged on the side of the protective cover 30 to ensure the uniformity of water flow.
[0063] Understandably, the shapes of the multiple second water passages 312 can be the same or different. When the multiple second water passages 312 have the same shape, the shape of the second water passage 312 can be elongated, circular, elliptical, or polygonal, etc. When the multiple second water passages 312 have different shapes, the shape of the second water passage 312 can be at least two of elongated, circular, elliptical, and polygonal. For example, some of the multiple second water passages 312 may be elongated and some may be circular.
[0064] In some embodiments, the water passage 31 includes a plurality of first water passages 311 and a plurality of second water passages 312. The first water passages 311 are located at the end of the protective cover 30, and the second water passages 312 are located on the side of the protective cover 30.
[0065] Multiple first water passage holes 311 can be evenly arranged at the end of the protective cover 30, and multiple second water passage holes 312 can be evenly arranged on the side of the protective cover 30 to ensure the uniformity of water flow.
[0066] The multiple first water passage holes 311 can have the same shape, for example, the first water passage hole 311 can be circular; the multiple second water passage holes 312 can have the same shape, for example, the second water passage hole 312 can be elongated.
[0067] Please refer to Figures 1 to 3 In some embodiments, the axial direction of the outer barrel 10 is the front-to-back direction X. The outer barrel 10 includes a front barrel body 11 and a rear barrel body 12 arranged along the front-to-back direction X. The protective cover 30 is disposed on the front barrel body 11. Correspondingly, the water electrolysis module 20 is disposed on the front barrel body 11 and is located outside the front barrel body 11.
[0068] The axial direction of the outer tub 10 is the front-to-back direction X, that is, the outer tub assembly 100 is used in a drum-type garment handling device.
[0069] During assembly, the front tub 11 and the rear tub 12 are joined together in the front-to-back direction X and secured with fasteners (such as bolts, screws, etc.). The front tub 11 has a clothing compartment opening at its front end for placing clothes, and the rear tub 12 has a drive device at its rear end for rotating the inner tub.
[0070] Understandably, the protective cover 30 can be located at the lower end of the front tub 11. Of course, the protective cover 30 can also be located on the bottom wall of the front tub 11. In this way, even if the water level inside the outer tub 10 is shallow, the water electrolysis module 20 can still be in full contact with the water for a long time, which is conducive to the generation of hydroxyl free radicals, thereby improving the sterilization, disinfection and deep cleaning effect of clothing.
[0071] Please refer to Figure 2 In some embodiments, the protective cover 30 is disposed on the front barrel 11, and the outer barrel assembly 100 also includes a heater 40 disposed in the rear barrel 12, with the distance between the water electrolysis module 20 and the heater 40 being 100-200mm.
[0072] The protective cover 30 is located on the front tank 11, and correspondingly, the water electrolysis module 20 is located on the front tank 11.
[0073] Understandably, the heater 40 is used to heat the water inside the outer tub 10 to increase the water temperature during washing, which can improve the solubility of the detergent and enhance its cleaning power, thereby improving the cleaning effect of the clothes.
[0074] In some embodiments, the heater 40 is located at the lower end of the rear tub 12. The heater 40 can be a heating tube that reciprocates within the outer tub 10; for example, the heating tube can be arranged in an S-shape. Alternatively, the heater 40 can be a heating element, heating wire, or the like.
[0075] Understandably, the distance between the water electrolysis module 20 and the heater 40 can be 100mm, 120mm, 130mm, 150mm, 170mm, 190mm or 200mm, etc.
[0076] Based on the above technical solution, the distance between the water electrolysis module 20 and the heater 40 is moderate. In this way, the high temperature generated by the heater 40 when heating the water in the outer tank 10 will not damage the water electrolysis module 20. Moreover, the water near the water electrolysis module 20 can be heated by the heater 40 to improve the electrolysis efficiency of the water electrolysis module 20, thereby increasing the concentration of hydroxyl radicals and further improving the sterilization, disinfection and deep cleaning effect of clothing.
[0077] In some embodiments, the axial direction of the outer barrel 10 is the front-to-back direction X. The outer barrel 10 includes a front barrel body 11 and a rear barrel body 12 arranged along the front-to-back direction X. A protective cover 30 is disposed on the rear barrel body 12. Correspondingly, the water electrolysis module 20 is disposed on the rear barrel body 12 and is located outside the rear barrel body 12.
[0078] The axial direction of the outer tub 10 is the front-to-back direction X, that is, the outer tub assembly 100 is used in a drum-type garment handling device.
[0079] During assembly, the front tub 11 and the rear tub 12 are joined together in the front-to-back direction X and secured with fasteners (such as bolts, screws, etc.). The front tub 11 has a clothing compartment opening at its front end for placing clothes, and the rear tub 12 has a drive device at its rear end for rotating the inner tub.
[0080] In some embodiments, the protective cover 30 may be located at the lower end of the rear tub 12. Alternatively, the protective cover 30 may be located on the bottom wall of the rear tub 12. This ensures that even if the water level inside the outer tub 10 is shallow, the water electrolysis module 20 can maintain sufficient contact with the water for an extended period, promoting the generation of hydroxyl radicals and thus improving the sterilization, disinfection, and deep cleaning effects on clothing.
[0081] In some embodiments, the protective cover 30 is disposed on the rear tank 12, and the outer tank assembly 100 also includes a heater 40 disposed inside the rear tank 12, with the distance between the water electrolysis module 20 and the heater 40 being 10-100mm.
[0082] The protective cover 30 is located on the rear tank 12, and correspondingly, the water electrolysis module 20 is located on the rear tank 12.
[0083] In some embodiments, the heater 40 is located at the lower end of the rear tub 12. The heater 40 can be a heating tube that reciprocates within the outer tub 10; for example, the heating tube can be arranged in an S-shape. Alternatively, the heater 40 can be a heating element, heating wire, or the like.
[0084] Understandably, the distance between the water electrolysis module 20 and the heater 40 can be 10mm, 20mm, 50mm, 70mm, 90mm or 100mm, etc.
[0085] Based on the above technical solution, the distance between the water electrolysis module 20 and the heater 40 is moderate. In this way, the high temperature generated by the heater 40 when heating the water in the outer tank 10 will not damage the water electrolysis module 20. Moreover, the water near the water electrolysis module 20 can be heated by the heater 40 to improve the electrolysis efficiency of the water electrolysis module 20, thereby increasing the concentration of hydroxyl radicals and further improving the sterilization, disinfection and deep cleaning effect of clothing.
[0086] Please refer to Figure 6 In some embodiments, the water electrolysis module 20 includes an anode electrode plate 21 and a cathode electrode plate 22, wherein the anode electrode plate 21 is parallel to or nearly parallel to the cathode electrode plate 22.
[0087] In some embodiments, cathode electrode sheets 22 are provided on both sides of the anode electrode sheet 21 in the thickness direction. For example, there is one anode electrode sheet 21 and two cathode electrode sheets 22, with the two cathode electrode sheets 22 respectively located on both sides of the anode electrode sheet 21 in the thickness direction. Of course, there may also be two anode electrode sheets 21 and three cathode electrode sheets 22, with the two anode electrode sheets 21 and three cathode electrode sheets 22 arranged alternately, and each anode electrode sheet 21 has cathode electrode sheets 22 on both sides in the thickness direction.
[0088] In some embodiments, anode electrode sheets 21 are provided on both sides of the cathode electrode sheet 22 in the thickness direction. For example, there are two anode electrode sheets 21 and one cathode electrode sheet 22, with the two anode electrode sheets 21 respectively located on both sides of the cathode electrode sheet 22 in the thickness direction. Of course, there can also be three anode electrode sheets 21 and two cathode electrode sheets 22, with the three anode electrode sheets 21 and two cathode electrode sheets 22 arranged alternately, and each cathode electrode sheet 22 has anode electrode sheets 21 provided on both sides in the thickness direction.
[0089] In some other embodiments, the water electrolysis module 20 includes an anode electrode plate 21 and a cathode electrode plate 22. The cathode electrode plate 22 may be located on the side of the anode electrode plate 21 facing away from the sealing ring 24; or, the cathode electrode plate 22 may be located on the side of the anode electrode plate 21 facing the sealing ring 24.
[0090] Please refer to Figure 3 and Figure 6 In some embodiments, the anode electrode 21 and the cathode electrode 22 are parallel to the axial direction of the protective cover 30. This design increases the axial length of the anode electrode 21 and the cathode electrode 22 in the protective cover 30 without the protective cover 30 protruding from the inner wall of the outer barrel 10, thereby increasing the facing area of the anode electrode 21 and the cathode electrode 22, which is conducive to the generation of more hydroxyl radicals at the same time.
[0091] In some other embodiments, the anode electrode 21 and the cathode electrode 22 may also be perpendicular to the axial direction of the protective cover 30.

[0101] Based on the above technical solution, by providing a first protrusion 112 on the outer wall of the outer barrel 10, the length of the threaded hole 1121 can be increased, thereby increasing the depth of the threaded fastener screwed into the threaded hole 1121, so as to ensure the stability of the water electrolysis module 20 fixed on the outer barrel 10.
[0102] In some embodiments, the inner wall of the outer barrel 10 is provided with a second protrusion, and the first protrusion 112 and the second protrusion are aligned in the axial direction of the protective cover 30.
[0103] The first protrusion 112 and the second protrusion are aligned in the axial direction of the protective cover 30, which can be understood as the first protrusion 112 and the second protrusion being arranged coaxially or nearly coaxially.
[0104] A portion of the threaded hole 1121 is located on the first protrusion 112, and another portion of the threaded hole 1121 is located on the second protrusion.
[0105] Based on the above technical solution, the length of the threaded hole 1121 can be further increased, thereby further increasing the depth of the threaded fastener screwed into the threaded hole 1121, so as to further ensure the stability of the water electrolysis module 20 fixed on the outer barrel 10.
