[0045] Please refer to Figures 1 to 4The present application provides a washing device, such as a washing machine. The washing device comprises a casing 10, an outer drum assembly 20, an inner drum assembly 30 and a driving device. The outer drum assembly 20 is fixedly accommodated in the casing 10. The outer drum assembly 20 comprises an outer drum body, and the inner drum assembly 30 is accommodated in the inner drum body 310. The inner drum assembly 30 further comprises an inner drum body 310, and an inner cavity of the inner drum body 310 is configured to accommodate laundry and the like. The inner drum body 310 is arranged to be positively rotatable and / or reversibly rotatable along its own axis relative to the outer drum body. The driving device drives the inner drum body 310 to perform the above-mentioned rotational movement.

[0046] In view of the above, the present application further provides an inner drum assembly 30, which comprises an inner drum body 310 as described above, a water quality detection device 320 and an adjusting device 330. The inner drum body 310 extends along a vertical direction and has a first region 310a close to a drum opening thereof and a second region 310b close to a drum bottom thereof. The water quality detection device 320 is movably mounted on a drum sidewall of the inner drum body 310 along the vertical direction, so as to be switchable between the first region 310a and the second region 310b. The adjusting device 330 is at least partially arranged in the inner drum body 310 and connected with the water quality detection device 320. When the washing device is in an idle state, the adjusting device 330 adjusts the water quality detection device 320 to move to the first region 310a. When the washing device is in a working state, the adjusting device 330 adjusts the water quality detection device 320 to move to the second region 310b.

[0047] In the technical solution provided by the present application, the water quality detection device 320 is arranged on the drum sidewall of the inner drum body 310 and is close to the drum sidewall of the inner drum body 310. On the one hand, the water quality detection process of the water quality detection device 320 is less likely to interfere with the working process of the inner drum body 310. On the other hand, the drum sidewall of the inner drum body 310 can stably support the water quality detection device 320, so that the water quality detection device 320 is not unbalancedly mounted due to the rotation of the inner drum body 310.

[0048] In addition, the setting of the adjusting device 330 helps to associate the working state of the washing device and the installation orientation of the water quality detection device 320. When the washing device is in an idle state, the water quality detection device 320 generally does not need to perform a detection operation, at this time, the adjusting device 330 adjusts the water quality detection device 320 to be at the first area 310a, closer to the barrel opening of the inner barrel 310, which helps the user to more easily perform regular processing such as disassembly, charging, state detection, etc. on the water quality detection device 320; on the contrary, when the washing device is in a working state, the water quality detection device 320 generally needs to perform a detection operation immediately or within a set period, at this time, the adjusting device 330 adjusts the water quality detection device 320 to be at the second area 310b, closer to the barrel bottom of the inner barrel 310, that is, deep into the water contained in the inner barrel 310, which helps the water quality detection device 320 to detect the water quality of the water body as needed.

[0049] In addition, the adjusting device 330 can adjust the depth range of the water body detected by the water quality detection device 320 by adjusting the water quality detection device 320 to move to any set area between the first area 310a and the second area 310b, thereby helping to obtain a water body with relatively stable speed, relatively few bubbles, and relatively few large impurities according to actual needs, and ultimately helping to improve the accuracy and reliability of water quality detection.

[0050] The present application does not need to limit the installation of the water quality detection device 320 to the drain line of the washing device, and can be set at any position in the inner barrel 310 according to actual needs, which helps to realize the installation flexibility and detection diversity of the water quality detection device 320.

[0051] It can be understood that the inner barrel 310 in the embodiment extends in the vertical direction, the vertical upper end forms a barrel opening, the vertical lower end forms a barrel bottom, and the barrel side wall connects the barrel opening and the barrel bottom. The first area 310a is directly arranged at the barrel opening of the inner barrel 310, or is arranged at a first preset distance from the barrel opening of the inner barrel 310 according to actual needs. The second area 310b is directly arranged at the barrel bottom of the inner barrel 310, or is arranged at a second preset distance from the barrel bottom of the inner barrel 310 according to actual needs. The first area 310a is at least higher than the second area 310b.

[0052] The water quality detection device 320 is close to the barrel side wall of the inner barrel 310, and can be optionally movably abutted with the barrel side wall of the inner barrel 310, or can be optionally connected with the barrel side wall of the inner barrel 310 in a non-contact manner. In a specific embodiment, the barrel side wall of the inner barrel 310 extends in the vertical direction and is provided with a sliding groove 311, and the water quality detection device 320 is movably connected with the sliding groove 311, which can be slidingly connected or rollingly connected.

[0053] The inner dimension and shape of the sliding groove 311 are set to be matched with the outer dimension and shape of the corresponding part of the water quality detecting device 320, so that the length extension of the sliding groove 311 can provide relatively accurate activity guide for the water quality detecting device 320, and avoid the water quality detecting device 320 from deviating during the activity. The width extension of the sliding groove 311 can provide two-side limiting for the water quality detecting device 320, so that the water quality detecting device 320 can be stably limited in the sliding groove 311 when the inner cylinder 310 rotates.

[0054] The water quality detecting device 320 has a detecting part 321a, and at least the detecting part 321a is exposed outside the sliding groove 311. In this way, the setting of the sliding groove 311 and the activity of the water quality detecting device 320 on the sliding groove 311 can reduce the adverse effect on the detecting function of the detecting part 321a, and ensure the normal operation of the detecting function of the detecting part 321a.

[0055] Further, in an embodiment, the sliding groove 311 is provided with a limiting groove 312 at the relative two side groove walls in the width direction of the sliding groove 311, and the limiting groove 312 extends along the vertical direction; the water quality detecting device 320 is respectively provided with a sliding convex 323 at the two sides, and the sliding convex 323 is in sliding connection with the limiting groove 312 on the same side. The concave-convex matching of the sliding convex 323 and the limiting groove 312 can help the sliding groove 311 to provide more accurate activity guide for the water quality detecting device 320, and can limit and stop the water quality detecting device 320 from moving towards the groove opening of the sliding groove 311 and towards the groove bottom of the sliding groove 311, so as to provide stable support for the water quality detecting device 320, and avoid the water quality detecting device 320 from being detached from the sliding groove 311 outwardly during the rotation of the inner cylinder 310.

[0056] The set groove section of the sliding groove 311 can directly define the first area 310a and the second area 310b. For example, the relative two ends of the sliding groove 311 along the length direction of the sliding groove 311 can define the first area 310a and the second area 310b, respectively.

[0057] In an embodiment, the chute 311 penetrates through the top of the inner cylinder body 310 to form an opening, and the opening is located to define the first region 310a; the inner cylinder assembly 30 further comprises a cover plate 340, which is movably connected with the inner cylinder body 310 to movably open and cover the opening. The opening is sized to allow the water quality detection device 320 to be wholly or partially detached from the opening outwardly or mounted into the chute 311 through the opening. In combination with the orientation of the first region 310a, during use of the washing device, the user can conveniently detach the water quality detection device 320 from the opening without detaching excessive mechanisms in the washing device, so that quality maintenance operations such as quality inspection, replacement, charging, and maintenance of the water quality detection device 320 can be performed.

[0058] Further, in an embodiment, the water quality detection device 320 comprises a detection body 321 and a battery body 322, and the detection body 321 is detachably electrically connected with the battery body 322. The detection body 321 is a structural body mainly performing water quality detection function, for example, a water quality detection sensor module or product with mature technology. The battery body 322 is a structural body mainly providing power supply for the detection body 321, for example, a battery. By connecting the detection body 321 and the battery body 322 into an integrated module, the water quality detection device 320 can be independently arranged inside the inner cylinder body without wired connection with the outside of the inner cylinder body through, for example, a cable. Of course, further, the communication connection between the detection body 321 and the external environment can also be set as a wireless connection mode, for example, but not limited to, Bluetooth, local area network, WiFi, and the like.

[0059] Among them, according to actual needs, the battery body 322 can be set as a disposable battery, and by detaching the battery body 322 outwardly from the opening and mounting it inwardly, the replacement of the disposable battery can be realized when the adjustment device 330 adjusts the water quality detection device 320 to move to the first region 310a.

[0060] Alternatively, the battery body 322 can be set as a rechargeable battery, and by detaching the battery body 322 outwardly from the opening and mounting it inwardly, the charging operation of the rechargeable battery can be realized when the adjustment device 330 adjusts the water quality detection device 320 to move to the first region 310a.

[0061] Of course, further, when the battery body 322 is a rechargeable battery as described above, in an embodiment, the inner cylinder assembly 30 further comprises a power supply device 350, which is arranged in the sliding groove 311 and is arranged close to the cylinder opening of the inner cylinder body 310, and the position of the power supply device 350 defines the first area 310a, and the power supply device 350 is provided with an electrical connection part; the water quality detection device 320 is provided with an electrical counterpart, which is electrically connected with the electrical connection part when the water quality detection device 320 is moved to the first area 310a. It can be understood that the power supply device 350 can be, for example, a power supply circuit specially arranged for the battery body 322, an electrical circuit electrically connected with the power supply system fixedly arranged in the washing device, or a circuit directly connected with the mains, without limitation. The electrical connection part and the electrical counterpart can be mating terminals, such as electrical plugs and electrical sockets, or two electrically matched electrical contacts, etc. In this way, when the adjusting device 330 adjusts the water quality detection device 320 to move to the first area 310a, the electrical counterpart of the battery body 322 is close to and electrically connected with the electrical connection part of the power supply device 350, and the idle time of the washing device is used to effectively charge the battery body 322 by the power supply device 350, which helps to improve the user experience.

[0062] Based on the above, in an embodiment, the inner cylinder assembly 30 further comprises a telescopic cover 360, which is sealingly arranged at the opening of the sliding groove 311 and is connected with the water quality detection device 320, and the telescopic cover 360 is arranged to be vertically telescopic deformed to be shortened and deformed when the water quality detection device 320 is moved to the first area 310a, and to be elongated and deformed when the water quality detection device 320 is moved to the second area 310b. The telescopic cover 360 is sealingly arranged at the opening of the sliding groove 311, and can dynamically seal the environment in the sliding groove 311 together with the water quality detection device 320, to avoid the clothes in the inner cavity of the inner cylinder body 310 interfering with the structure in the sliding groove 311, causing damage to the clothes or blockage of the structure. Specifically, when the water quality detection device 320 slides along the sliding groove 311, the sliding groove 311 can be roughly divided into a first groove segment forming the first area 310a and a first groove segment forming the second area 310b. The telescopic cover 360 can be arranged at the first groove segment and / or the second groove segment as needed.

[0063] The specific structure of the telescopic cover 360 is not limited, for example, it can be a cover made of an elastic material such as rubber that can be elastically deformed; or a cover composed of a plurality of telescopic joints successively movably sleeved; or a cover composed of a foldable structure such as a telescopic bellows, etc.

[0064] It should be noted that when the telescopic cover 360 is sealingly connected to the outer circumferential side of the chute 311, the telescopic cover 360 can achieve the sealing arrangement of the space in the chute 311, thereby playing a role such as waterproofing. In addition, the outer surface of the telescopic cover 360 and the barrel side wall of the inner barrel body 310 can be substantially flush, so that the overall barrel side wall of the inner barrel body 310 remains substantially flat, avoiding the formation of too many unnecessary concave or convex structures that interfere with the clothes inside the inner barrel body 310 and cause damage to the clothes.

[0065] Based on any of the above embodiments, in actual application, the positions of the first region 310a and the second region 310b can be set to be fixed regardless of the operation of the washing device in any working mode. Alternatively, the positions of the first region 310a and the second region 310b can be set to be associated with each working mode of the washing device, for example, when the working modes of the washing device include a water injection state, the positions of the first region 310a and the second region 310b can be adjusted to be different according to the different target water injection amounts, i.e., target water levels, in the water injection state.

[0066] In addition, the movement adjustment of the water quality detection device 320 by the adjustment device 330 needs to be associated with the working state of the washing device. The association manner of the two is not limited:

[0067] In an embodiment, a control device is pre-set inside the washing device, and the control device is electrically connected to the driving device and the adjustment device 330, respectively. The control device can associate the operation of the driving device and the adjustment device 330 according to actual needs, for example, when the control device controls the driving device to operate to drive the inner barrel body 310 to rotate, the control device can control the adjustment device 330 to operate to drive the water quality detection device 320 to move to the second region 310b and control the water quality detection device 320 to operate the water quality detection function immediately or after a time delay. Conversely, for example, when the control device controls the driving device to stop operating, the inner barrel body 310 stops rotating, at this time, the control device can control the adjustment device 330 to drive the water quality detection device 320 to reset to the first region 310a in the opposite direction.

[0068] Or in an embodiment, the working states of the washing device include a water filling state and a drying state; the adjusting device 330 includes a water absorbing member 331 and an elastic member 332. Wherein, the water absorbing member 331 is fixedly connected with the water quality detecting device 320, and the water absorbing member 331 absorbs water when the washing device is in the water filling state, so as to drive the water quality detecting device 320 to move to the second area 310b; the water absorbing member 331 loses water when the washing device is in the drying state; the elastic member 332 is arranged in the sliding groove 311 and connected between the inner cylinder 310 and the water quality detecting device 320, and when the water absorbing member 331 loses water, the elastic member 332 drives the water quality detecting device 320 to reset to the first area 310a. In this way, by means of the water absorbing member 331, the water filling state and the drying state of the washing device can be quickly sensed. Wherein, when the washing device is in the water filling state, the water absorbing member 331 absorbs water and gradually increases its own mass, and in combination with the above-mentioned arrangement that the second area 310b is arranged vertically below the first area 310a, the water quality detecting device 320 can gradually slide down under the guidance of the mass of the water absorbing member 331 and move to the second area 310b; at this time, the elastic member 332 is stretched or compressed to form an elastic restoring force. When the washing device is in the drying state (whether in the heat drying mode or the spin drying mode), the water absorbed in the water absorbing member 331 is gradually removed, and its own mass gradually decreases to be less than the elastic restoring force, so that the water quality detecting device 320 can be reset to the first area 310a under the driving of the elastic restoring force of the elastic member 332, to complete the activity switching between the first area 310a and the second area 310b without power.

[0069] It can be understood that the water absorbing member 331 is generally arranged to have water absorbing performance and water removing performance. Wherein, the water absorbing performance and the water removing performance can be realized by the material of the water absorbing member 331, for example, the water absorbing member 331 is arranged to be a structure made of high molecular material, cloth with large water absorbing capacity, water absorbing sponge and the like. Or, the water absorbing performance and the water removing performance can be realized by the structural design of the water absorbing member 331, for example, the water absorbing member 331 is arranged to be a cavity structure which can allow water to enter and exit, and the entering and exiting of water can be set by specific conditions such as opening and closing members, valve structures and the like. For example, a water storage container, a water bag and the like. Without limitation. It should be noted that the material design and / or structural design of the water absorbing member 331 can be adjusted according to the buoyancy and the density, so that the density of the water absorbing member 331 after absorbing water is greater than the density of water. And according to the actual needs, the depth of the water absorbing member 331 in the water after absorbing water can be adjusted.

[0070] Further, in an embodiment, the water quality detecting device 320 has a detecting portion 321a; the water absorbing member 331 includes a weighted portion 331a and an expanding portion 331b, both of which are connected with the water quality detecting device 320 and spaced from the detecting portion 321a, and the expanding portion 331b generates an expanding deformation when absorbing water, so as to be able to expand and protrude from the chute 311 to the inner cavity of the inner cylinder 310.

[0071] It can be understood that the weighted portion 331a is arranged to mainly serve as a part to drive the water quality detecting device 320 to slide down to the second region 310b and reset to the first region 310a in combination with the elastic member 332, and a larger mass difference before and after absorbing water can be generated, and the weighted portion 331a is not limited to whether it needs to generate a structural deformation before and after absorbing water. The expanding portion 331b is arranged to generate a structural deformation before and after absorbing water. When the expanding portion 331b generates a positive expanding deformation after absorbing water, the expanding portion 331b at least partially protrudes from the chute 311 and can extend into the inner cavity of the inner cylinder 310, so as to generate a certain interference with the clothes during the washing process of the clothes in the inner cylinder 310, which is equivalent to patting the clothes, and is helpful to improve the cleaning effect of the clothes. When the expanding portion 331b generates a negative expanding deformation after dehydration, it is also possible to make the expanding portion 331b reduce or completely eliminate the part protruding outward from the chute 311. The specific material or structural design of the expanding portion 331b can also be referred to the above. It should be noted that the protruding height of the expanding portion 331b, the hardness after positive expansion and the like need to be set within a reasonable range, and it is necessary to avoid that the clothes are damaged due to too large interference with the clothes.

[0072] In addition, in an embodiment, the inner cylinder 310 is provided with a water inlet, and when the washing device is in the water injection state, the water inlet is used to access external water; at least the weighted portion 331a of the water absorbing member 331 is arranged vertically below the water inlet. In this way, when the water inlet accesses external water into the inner cylinder 310, at least the weighted portion 331a of the water absorbing member 331 can quickly obtain water, so as to drive the water quality detecting device 320 to move according to actual needs.

[0073] Of course, in other embodiments, the water body absorbed by the water absorption member 331 can be set as the cleaning water body accessed by the washing device when it is in the water filling state. In order to reduce the waste of the cleaning water body, the water absorption member 331 can be set as the waste water discharged outwardly when the washing device last cleaned the clothes. Specifically, an additional water storage space can be additionally arranged in the washing device body, which can temporarily transfer the waste water discharged when the washing device last cleaned the clothes, and access the water absorption member 331 when needed. Further, the waste water stored in the water storage space can be set as a relatively clean water body basically meeting the needs. And / or the waste water stored in the water storage space can be set as being discharged when the control device determines that the washing device does not start the next working state within a preset time length, so as to avoid the pollution caused by the long-time storage of the waste water in the water storage space.

[0074] In addition, in other embodiments, the adjusting device 330 can be directly set as being composed of the driver alone, at this time, the driver can be a device such as a linear cylinder having a translational output along the vertical direction. Of course, the adjusting device 330 can also be set as being composed of the combination of the driver and the transmission assembly. When the driver is a device such as a linear cylinder having a translational output, the transmission assembly can be a transmission scheme maintaining the linear output, and can achieve the purposes of reversing, speed regulation, etc. through the transmission assembly according to actual needs. When the driver is a device such as a motor having a rotational output, the transmission assembly can be a transmission scheme converting rotation into linearity, such as a gear and rack assembly, a screw and nut assembly, etc.

[0075] When the adjusting device 330 is an electric control device as described above, further, in an embodiment, the inner cylinder assembly further includes a water level detection device and a control device, the water level detection device is arranged in the inner cylinder body 310, and is used to sense the water level value in the inner cylinder body 310; the control device is electrically connected with the water level detection device and the adjusting device 330 respectively, so as to control the adjusting device 330 to drive the water quality detection device to move to the second area 310b when the water level value meets a preset condition. The water level detection device can be a device detecting the water level value in the inner cylinder body 310 in any feasible way, such as detecting the position of a floating member, weighing the weight of the water body, etc. The above-mentioned preset condition can be to confirm the water level threshold value, which can be a default water level value, or a water level value confirmed by the user in advance. When the actually measured water level value in the inner cylinder body 310 reaches the water level threshold value, it means that the inner cylinder body 310 currently meets the requirements of the detection environment of the water quality detection device 320, and the detection function thereof can be run. At this time, the water quality detection device 320 can be driven by the adjusting device 330 to extend into the second area 310b.

[0076] The above merely describes the preferred embodiments of the present application, and is not intended to limit the patent scope of the present application. Any equivalent structural changes made according to the content of the present application specification and drawings, or direct / indirect application in other related technical fields, are included in the patent protection scope of the present application.
