DETAILED DESCRIPTION

[0026] In order to make the objectives, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and should not be used to limit the present application.

[0027] In the specific embodiments, each specific technical feature described can be combined in any suitable manner without contradiction, for example, different embodiments and technical solutions can be formed by combining different specific technical features. In order to avoid unnecessary repetition, various possible combinations of each specific technical feature in the present application are not described again.

[0028] In the following description, the terms "first", "second", and the like are merely used to distinguish different objects, and do not indicate that the objects have the same or related relationship. It should be understood that the terms "upper", "lower", "outer", "inner", "left", and "right" are the positions in the normal use state, and the terms "left" and "right" represent the left and right directions shown in the specific schematic diagram, which can be the left and right directions in the normal use state or not.

[0029] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Unless otherwise specified, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element. "A plurality of" means two or more.

[0030] This invention provides a garment processing device that can be used in washing machines, washer-dryer combos, etc. It should be noted that the application scenarios of this invention do not limit the garment processing device.

[0031] The following explanation uses a garment handling device as a washing machine as an example. Washing machines typically have two garment loading / unloading methods: top-loading and front-loading. Top-loading washing machines have an opening at the top for loading and unloading clothes, such as top-loading or agitator washing machines. Front-loading washing machines have an opening at the front for loading and unloading clothes. Front-loading washing machines can be integrated into the user's sink or countertop, and their flat top can also be used as a countertop. The garment handling device provided in this embodiment can be either a top-loading or front-loading washing machine; unless otherwise specified, the following explanation uses a top-loading washing machine as an example.

[0032] like Figure 1 As shown, an embodiment of the present invention provides a clothing processing device, including a tub 1, a drive unit 2, and a disinfection device 4. The tub 1 has an internal cavity 11. The cavity 11 includes a separated first cavity 111 and a return channel 112, the first cavity 111 being used to accommodate clothing. The cavity 11 has a spaced portion at one end in its extending direction (…). Figure 1 The upper part (as shown) is open to facilitate the user to put clothes into and take out clothes from the cavity 11. Generally, the bucket body 1 is an axisymmetric structure, so the direction of its axis is the axial direction of the cavity 11; in special cases, if the bucket body 1 is not an axisymmetric structure, the direction of the longest dimension of the bucket body 1 can be understood as the axial direction of the cavity 11.

[0033] The driving component 2 is disposed in the first cavity 11 to drive the liquid to flow between the first cavity 111 and the return channel 112. The clothes in the cavity 11 will move with the liquid, thereby realizing the rubbing of the clothes.

[0034] It should be noted that the driving element 2 in the embodiments of the present invention can take various forms, for example... Figure 5In the shown embodiment, the driving member can be a pulsator 21, and the pulsator 21 is arranged at the bottom of the cavity 11. Figure 5 In the shown embodiment, the driving member can be a pulsator 21, and the pulsator 21 is arranged at the bottom of the cavity 11. Figure 5 In the shown embodiment, the driving member can be a pulsator 21, and the pulsator 21 is arranged at the bottom of the cavity 11.

[0035] In the shown embodiment, the volume of the reflux passage 112 is much smaller than the volume of the first cavity 111, for example, the volume of the reflux passage 112 is less than 1 / 5 of the volume of the first cavity 111, and the first cavity 111 is used to accommodate the clothes to be washed. During the washing process, the liquid in the first cavity 111 moves in the first cavity 111 under the action of the driving member. Since the reflux passage 112 is in flow communication with the first cavity 111, part of the liquid in the first cavity 111 will enter the reflux passage 112 and then return to the first cavity 111 from the reflux passage 112.

[0036] In the shown embodiment, the disinfecting device 4 is arranged in the reflux passage 112, that is, the disinfecting device 4 can move under the impact of the liquid to release the disinfecting substance, so that the disinfecting device 4 in the reflux passage 112 is not disturbed by the clothes in the first cavity 111.

[0037] It should be noted that the connection relationship between the disinfecting device 4 and the reflux passage 112 is not limited in the shown embodiment, that is, the disinfecting device 4 can move relative to the reflux passage 112 during the process of the liquid passing through the reflux passage 112, for example, the disinfecting device 4 can translate and / or rotate relative to the reflux passage 112, that is, the disinfecting device 4 can translate along a set direction relative to the reflux passage 112; the disinfecting device 4 can also rotate around a set direction; the disinfecting device 4 can also rotate around a set direction and translate along a set direction. The set direction can be a vertical direction, a horizontal direction, or other directions.

[0038] The reflux passage 112 can limit the freedom of the disinfecting device 4 in a certain direction or multiple directions to maintain the positional relationship between the disinfecting device 4 and the reflux passage 112 in a certain direction. Of course, the disinfecting device 4 can also be completely free and unrestricted in the reflux passage 112, as long as the disinfecting device 4 can move relative to the reflux passage 112 during the washing process of the clothes processing device.

[0039] The laundry treatment device provided by the embodiment of the present application comprises a barrel, a driving member and a sterilization device. The barrel comprises a first cavity and a reflux channel. The driving member is arranged in the first cavity of the barrel to drive the liquid to flow between the first cavity and the reflux channel. The sterilization device is arranged in the reflux channel to move under the impact of the liquid and release sterilization substances. The sterilization device is arranged in the reflux channel, so that the sterilization device in the reflux channel moves under the impact of the liquid, and the laundry in the first cavity does not enter the reflux channel, so that the impact of the liquid on the sterilization device is not disturbed by the laundry, the rotation efficiency of the sterilization device is improved, the release efficiency of the sterilization substances in the sterilization device is improved, and the cleaning effect of the laundry treatment device is improved.

[0040] In some embodiments, the barrel comprises an inner barrel and an outer barrel. The inner barrel is internally provided with the first cavity. The outer barrel is arranged outside the inner barrel, and the reflux channel is formed between the outer barrel and the inner barrel. The sterilization device is arranged in the reflux channel between the inner barrel and the outer barrel. Under the action of the driving member, the liquid can enter between the inner barrel and the outer barrel, so as to impact the sterilization device in the reflux channel, so that the sterilization device moves relative to the reflux channel to release sterilization substances. The sterilization substances mix with the liquid in the reflux channel and then enter the inner barrel.

[0041] As shown in Figure 1 The embodiment of the present application also comprises a cover plate 3 arranged in the cavity 11. The cover plate 3 divides the cavity 11 into the first cavity 111 and the reflux channel 112 in communication. The cover plate 3 blocks the laundry from entering the reflux channel 112. The embodiment of the present application does not limit the arrangement direction of the cover plate 3 in the cavity 11, that is, the extension direction of the cover plate 3 can be parallel to the axial direction of the barrel 1 (the up-down direction as shown in Figure 1 The cover plate 3 can be arranged in the cavity 11 of the barrel 1 along the axial direction, and the upper end of the cover plate 3 forms a bent part connected with the barrel 1. Of course, in other embodiments, the connection position of the cover plate and the barrel can also be other positions on the cover plate.

[0042] The cover plate 3 is connected with the barrel 1 at the end of the cover plate 3, for example, Figure 1 The cover plate 3 is arranged in the cavity 11 of the barrel 1 along the axial direction, and the upper end of the cover plate 3 forms a bent part connected with the barrel 1. Of course, in other embodiments, the connection position of the cover plate and the barrel can also be other positions on the cover plate.

[0043] As shown in Figure 2 and 3 As shown in Figure 4As shown, the cover 41 is internally provided with sterilization particles 412, wherein the cover 41 is internally hollow, and the sterilization particles 412 are arranged in a second cavity 411 in the interior of the cover 41. It should be noted that the second cavity 411 is not a completely closed cavity, and the second cavity 411 can be in communication with the reflux channel 112 outside the sterilization device 4, so that the liquid in the reflux channel 112 can enter the second cavity 411. During the washing process, the liquid can impact the sterilization particles 412 in the second cavity 411, so that the sterilization particles 412 release sterilization substances and dissolve in the liquid. The liquid with the sterilization substances can flow out of the second cavity 411 to the reflux channel 112 again. The liquid in the reflux channel 112 has a certain power under the action of the driving member, so as to drive the liquid mixed with the sterilization substances to flow into the first cavity 111, so as to sterilize and disinfect the clothes in the first cavity 111.

[0044] It should be noted that the sterilization particles 412 are particles capable of releasing sterilization substances at a slower speed. The components of the sterilization particles include, but are not limited to, solid compositions such as bleaching agents, disinfectants and detergents. The shape, size and components of the sterilization particles are not limited in the embodiment of the present application, and the specific speed value of the slower release speed is also not limited. As long as the content of the released substance meets the actual demand within a set time, for example, 0.1-1 grams of sterilization substances are released within 1 minute. Of course, it can also be another release speed, as long as it can meet the actual requirements.

[0045] The blade 42 is connected to the outer side 41a of the cover 41, and the outer side 41a of the cover 41 represents the side of the cover 41 relatively far away from the second cavity 411. The blade 42 and the cover 41 can be connected in various ways. The blade 42 can be detachably fixedly connected to the cover 41 by clamping. The blade 42 can also be permanently fixedly connected to the cover 41 by injection molding or welding. As long as the blade 42 and the cover 41 remain relatively stationary in the state of fluid motion in the embodiment of the present application, so that the blade 42 can drive the cover 41 to move.

[0046] The outer side of the cover 41 can be directly contacted with the liquid. The blade 42 can drive the cover 41 to move relative to the reflux channel 112 under the movement of the liquid, so that the sterilization particles 412 in the second cavity 411 can release sterilization substances. The moving liquid has a certain kinetic energy and potential energy. During the contact between the liquid and the blade 42, the energy of the liquid is at least partially transferred to the blade 42, so that the blade 42 can drive the cover 41 to move.

[0047] The movement of the cover 41 can be in various ways, such as the blade 42 can drive the cover 41 to translate along a set direction; the blade 42 can also drive the cover 41 to rotate around a set direction; the blade 42 can also drive the cover 41 to both rotate around a set direction and translate along a set direction.

[0048] like Figures 2-4 As shown, the cover 41 includes an end wall 415 and a side wall 414. The end wall 415 is positioned axially along the cover 41. Figure 4 As shown in the left-right direction (which can be considered as the direction of the dashed line), the sidewall 414 connects to two endwalls 415 to jointly form the second cavity 411. The angle θ between the extending direction of the endwall 415 and the extending direction of the sidewall 414 can be less than or equal to 90 degrees. Figures 2-4 In the illustrated embodiment, the included angle θ is equal to 90 degrees. In other embodiments, the included angle θ can be 45 degrees, 60 degrees, etc. The blade 42 is disposed on the outer side of the sidewall 414 (i.e., Figure 2 The outer side 41a of the cover shown. The first surface 415a of the end wall 415 away from the side wall 414 may be provided with a pivot 415b for easy assembly with the cover plate.

[0049] like Figures 2-4 As shown, the sidewall 414 and / or endwall 415 have multiple through-holes 413. The through-holes 413 connect the second cavity 411 and the washing chamber. The diameter of the through-holes 413 is smaller than a set value. That is, the size of the through-holes 413 is set to allow liquid to pass between the inside and outside of the second cavity 411, but the disinfection particles 412 inside the second cavity 411 are not easily allowed to flow out of the cover 41 through the through-holes 413. Correspondingly, debris such as lint outside the cover 41 is also not easily allowed to flow into the second cavity 411 through the through-holes 413, thereby reducing the impact of debris on the release efficiency of the disinfection particles.

[0050] The water passage hole 413 may be provided only on the side wall 414; the water passage hole 413 may also be provided only on the end wall 415; in some embodiments, the water passage hole may be provided on both the side wall and the end wall, and the specific location of the water passage hole is not limited in the embodiments of the present invention. Of course, in some embodiments, the location of the water passage hole 413 may be set on the cover 41 according to the direction of liquid flow, for example, as... Figure 3 As shown, when the water flows from top to bottom, the water passage hole 413 is provided on the side wall 414 so that the water passage hole 413 faces the direction of water flow, which can improve the water passage efficiency of the water passage hole.

[0051] like Figure 5As shown, in some embodiments, the two ends of the cover 41 are movably connected to the cover plate 3 so that the cover 41 moves relative to the cover plate 3 under liquid impact. It should be noted that the two ends of the cover 41 refer to the axial direction of the cover 41. Figure 3 The two ends (in the direction of the dotted line shown) can also be understood as the two ends in the direction of the maximum extension of the cover 41, or the two ends in other directions. The connection between the two ends of the cover 41 and the cover plate 3 indicates that the cover 41 and the cover plate 3 are in direct contact and have a connection relationship. Installing the cover 41 on the cover plate 3 allows the cover 41 to move relative to the cover plate 3. Then, fixing the cover plate 3 to the barrel 1 reduces the difficulty of assembling the disinfection device and also reduces the cost of disassembly, assembly, and maintenance.

[0052] The present invention does not limit the connection form between the cover 41 and the cover plate 3, as long as the cover 41 and the cover plate 3 have a certain relative positional relationship and the cover 41 can be kept in the return channel 112.

[0053] In some embodiments, combined with Figure 1 and Figure 5 As shown, the cover plate 3 extends from a position close to the drive member 2 towards a position away from the drive member 2. Since the drive member 2 is located at the bottom of the cavity 11 inside the barrel 1, the position close to the drive member 2 can be understood as being close to the drive member 2; the position away from the drive member 2 can be understood as being relatively far from the bottom of the barrel 1, which is the top of the barrel 1. That is to say, the extension direction of the cover plate 3 is in the vertical direction of the barrel 1, but this does not mean that the extension direction of the cover plate 3 is parallel to the axis of the barrel 1. The extension direction of the cover plate 3 can also form a set angle with the axis of the barrel 1, as long as the extension direction of the cover plate 3 is approximately along the vertical direction of the barrel 1. The liquid flow direction in the return channel 112 formed between the cover plate 3 and the barrel 1 is also approximately from bottom to top.

[0054] The cover plate 3 has an inlet 31 at the end near the drive component 2. The liquid in the first cavity 111 moves under the action of the impeller 21. The inlet 31 is relatively close to the impeller 21. The rotation of the impeller causes the liquid and / or clothing around the impeller 21 to agitate. Since the pressure in the return channel 112 is lower than the pressure in the first cavity 111, under the action of negative pressure, the liquid in the first cavity 111 can flow through the inlet 31 into the return channel 112, and then flow out from the top of the return channel 112 back into the first cavity 111. The liquid returning to the first cavity 111 from the top can have an impact effect on the clothing in the first cavity 111.

[0055] The embodiment of the present application extends the cover plate from the position close to the driving member to the direction away from the driving member, so that the liquid in the backflow channel flows under the action of the driving member, without the need to set an additional driving device to drive the sterilization device in the backflow channel to move, thereby saving the energy consumption of the clothes treatment equipment; meanwhile, the liquid guided by the backflow channel can also impact the clothes in the first cavity, thereby further improving the cleanliness of clothes washing.

[0056] In some embodiments, the cover plate 3 extends from the position close to the driving member 2 to the direction away from the driving member 2. Figure 1 and Figure 5 As shown in Figs. 1 and 2, the cover plate 3 is provided with a water outlet 32 communicating the first cavity 111 and the backflow channel 112, and the water outlet 32 can be arranged at the position close to the top of the tub 1. It should be noted that the water outlet 32 can be formed by the gap between the end of the cover plate 3 in the extending direction and the inner wall of the tub 1; of course, the water outlet 32 can also be an opening arranged on the cover plate 3, and the water outlet 32 can be arranged in the region at a certain distance from the end of the cover plate 3. The position of the water outlet 32 can be close to the top of the tub 1, so that the liquid flowing out from the water outlet 32 has a high potential energy, which is conducive to impacting and washing the clothes in the first cavity 111. It can be understood that in some embodiments, the specific form of the cover plate 3 can be a cascade plate, and the sterilization device is arranged between the cascade plate and the inner wall of the tub closest to the cascade plate.

[0057] In some embodiments, the water outlet can be arranged at the middle part of the cover plate, that is, the sterilization device 4 can be located on the same side of the water inlet and the water outlet. For example, in the case where the cover plate extends in the up-down direction, the water outlet is arranged at the middle part in the up-down direction, and the sterilization device can be arranged below the water outlet or above the water outlet in the backflow channel, as long as the sterilization device is arranged in the backflow channel.

[0058] In the embodiment of the present application, the cover plate 3 extends from the position close to the driving member 2 to the direction away from the driving member 2. Figure 1 and Figure 5 As shown in Figs. 1 and 2, the cover plate 3 is provided with a water outlet 32 communicating the first cavity 111 and the backflow channel 112, and the water outlet 32 can be arranged at the position close to the top of the tub 1. It should be noted that the water outlet 32 can be formed by the gap between the end of the cover plate 3 in the extending direction and the inner wall of the tub 1; of course, the water outlet 32 can also be an opening arranged on the cover plate 3, and the water outlet 32 can be arranged in the region at a certain distance from the end of the cover plate 3. The position of the water outlet 32 can be close to the top of the tub 1, so that the liquid flowing out from the water outlet 32 has a high potential energy, which is conducive to impacting and washing the clothes in the first cavity 111. It can be understood that in some embodiments, the specific form of the cover plate 3 can be a cascade plate, and the sterilization device is arranged between the cascade plate and the inner wall of the tub closest to the cascade plate. Figure 5As shown, the minimum distance L from the disinfection device 4 to the outlet 32 ​​is less than or equal to 10 cm. It should be noted that the disinfection device 4 can have an irregular structure; that is, the distances from various points on the disinfection device 4 to the outlet 32 ​​can be unequal. Therefore, this embodiment of the invention limits the minimum distance L from the disinfection device 4 to the outlet 32, allowing the disinfection device 4 to be closer to the outlet 32 ​​relative to the inlet 31. The liquid in the return channel 112 becomes a liquid containing disinfectant after passing through the disinfection device 4. This embodiment of the invention reduces the distance between the disinfection device 4 and the outlet 32, allowing the liquid containing disinfectant to flow quickly from the outlet 32 ​​to the first cavity 111, thus reducing the dissipation of disinfectant in the liquid.

[0059] In some embodiments, such as Figure 1 As shown, the dimension of the outlet 32 ​​in the extension direction of the cover plate 3 is smaller than a set value, which can be less than 15mm, so that the outlet 32 ​​has a slender structure. The liquid flowing from the outlet 32 ​​to the first cavity 111 can form a waterfall to enhance the impact effect of the fluid on the clothes in the first cavity 111, thereby improving the cleaning degree of the clothing treatment equipment.

[0060] In some embodiments, such as Figure 6 As shown, the extension direction of the cover plate 3 is parallel to the extension direction of the barrel body 1. It should be noted that the extension direction of the cover plate 3 can be understood as the direction of its maximum length. Generally, if the barrel body is an axisymmetric structure, then the axial direction of the barrel body is its extension direction. In special cases, if the barrel body is not an axisymmetric structure, the direction of its maximum length can be understood as the axial extension direction of the barrel body. In this embodiment of the invention, the extension direction of the cover plate 3 is parallel or approximately parallel to the extension direction of the barrel body 1. Approximately parallel means that the angle between the extension directions of the cover plate and the barrel body is less than or equal to 10°.

[0061] In this embodiment of the invention, by making the extension direction of the cover plate parallel to the extension direction of the barrel, the liquid flow path in the return channel is shorter at a certain height, which helps to reduce the energy loss of the liquid in the return channel, thereby improving the water flow efficiency of the return channel, and thus improving the efficiency of the liquid passing through the disinfection device in the return channel.

[0062] In some embodiments, such as Figure 5 and Figure 6 As shown, the directions of the two ends of the cover 41 are perpendicular or parallel to the extension direction of the cover plate 3.

[0063] like Figure 5 As shown, the extension direction of the cover plate 3 is approximately parallel to the extension direction of the barrel 1, and the directions of the two ends of the cover 41 are perpendicular to the extension direction of the barrel 1. Therefore, the directions of the two ends of the cover 41 are perpendicular to the extension direction of the cover plate 3.

[0064] As Figure 6 shown, the extension direction of the cover plate 3 is substantially parallel to the extension direction of the barrel 1, and the direction in which the two ends of the cover body 41 are located is also substantially parallel to the extension direction of the barrel 1, so the direction in which the two ends of the cover body 41 are located is parallel to the extension direction of the cover plate 3.

[0065] Of course, in other embodiments, the direction in which the two ends of the cover body 41 are located can be set at an acute angle to the extension direction of the cover plate 3.

[0066] In some embodiments, as Figure 5 shown, the angle between the water-facing surface 42a of the vane 42 and the direction in which the two ends of the cover body 41 are located can affect the movement mode of the cover body, and it should be noted that the water-facing surface 42a of the vane 42 refers to the surface of the vane that is opposite to the direction of the water flow, and at different times, the water-facing surface can be the surface of different vanes.

[0067] In the case where the two ends of the cover body 41 in the extension direction are movably connected to the cover plate 3, the angle between the water-facing surface 42a of the vane 42 and the extension direction in which the two ends of the cover body 41 are located is less than or equal to 30 degrees, which can be considered as that the surface of the vane 42 is substantially parallel to the extension direction in which the two ends of the cover body 41 are located, and the vane 42 can drive the cover body 41 to rotate relative to the reflux passage 112 under the action of the liquid or the laundry; for example, Figure 5 as shown, the water-facing surface 42a of the vane 42 extends in the left-right direction of Figure 5 , and the direction in which the two ends of the cover body 41 are located is also the left-right direction of Figure 5 , so the water-facing surface 42a of the vane is consistent with the direction in which the two ends of the cover body 41 are located, and the angle therebetween is 0 degrees. As another example, Figure 6 as shown in the embodiment, the angle β between the water-facing surface 42a of the vane 42 and the direction in which the two ends of the cover body 41 are located is substantially 30 degrees, which can be considered as that the surface of the vane 42 is substantially parallel to the extension direction in which the two ends of the cover body 41 are located, and the vane 42 can drive the cover body 41 to rotate relative to the reflux passage 112 under the action of the liquid or the laundry.

[0068] Alternatively, the angle between the water-facing surface 42a of the vane 42 and the extension direction in which the two ends of the cover body 41 are located is greater than or equal to 70 degrees, which can be considered as that the surface of the vane 42 is substantially perpendicular to the extension direction in which the two ends of the cover body 41 are located, and the vane 42 can drive the cover body 41 to translate relative to the reflux passage 112 under the action of the liquid or the laundry. For example, Figure 5As shown, in some embodiments, the cover plate 3 comprises a transparent portion 33 through which the movement of the sterilization device can be observed. The transparent portion 33 can be made of glass, so that the user can easily observe the working state of the sterilization device 4 in the reflux channel 112. In some embodiments, a light-emitting element can be arranged in the reflux channel, and the reflux channel is illuminated by the light-emitting element, so that the user can clearly understand the working state of the sterilization device in different environments, and the user experience comfort is improved.

[0069] The above merely illustrates the preferred embodiments of the present application, but is not used to limit the protection scope of the present application.
