[0025] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the invention as detailed in the appended claims.

[0026] In related technologies, turbidity detection devices are placed in a liquid environment to detect the turbidity of the liquid. However, due to prolonged or frequent immersion in a liquid environment, dirt from the liquid can easily accumulate on and around the turbidity detection device, severely affecting the accuracy of turbidity detection.

[0027] To address the aforementioned technical problems, this embodiment proposes a turbidity detection device. The device includes a turbidity detection unit and a cleaning unit. The cleaning unit includes a cleaning structure and a limiting structure, with the cleaning structure connected to the limiting structure. In a non-liquid environment, the cleaning structure is located within the gap between the light emitting part and the light receiving part. In a liquid environment, the cleaning structure is detached from the gap between the light emitting and light receiving parts. The limiting structure limits the distance, direction, and / or angle at which the cleaning structure detaches from the turbidity detection unit. In this embodiment, in a non-liquid environment, the cleaning part is located within the gap between the light emitting and light receiving parts, preventing dirt from accumulating between them; instead, it accumulates on the cleaning structure. In a liquid environment, the cleaning structure detaches from the gap between the light emitting and light receiving parts to detect the turbidity of the liquid. Simultaneously, when the cleaning structure detaches from the turbidity detection unit, dirt adhering to the cleaning structure and dirt near the turbidity detection unit are also carried away, resulting in more accurate turbidity detection results.

[0028] The technical solution of this embodiment will be described in detail below with reference to the accompanying drawings. In the absence of conflict, the following embodiments and implementation methods can be combined with each other.

[0029] According to an exemplary embodiment, this embodiment proposes a turbidity detection device. This turbidity detection device can be applied to any scenario requiring turbidity detection. For example, it can determine the cleaning effect of clothes by detecting the turbidity of washing water, determine water pollution by detecting water turbidity, and can also perform related laboratory analysis tests by detecting liquid turbidity. The turbidity detection device in this embodiment detects the turbidity of liquid substances, which can be water.

[0030] like Figures 1-3 As shown, the turbidity detection device in this embodiment includes a turbidity detection unit 1, referring to... Figure 3 The turbidity detection unit 1 includes a turbidity detection body 13 and a light emitting part 11 and a light receiving part 12 located on the turbidity detection body 13. The light emitting part 11 and the light receiving part 12 are arranged opposite to each other, and there is a gap 14 between the light emitting part 11 and the light receiving part 12. In a liquid environment, liquid enters the gap 14 between the light emitting part 11 and the light receiving part 12. The light emitted by the light emitting part 11 passes through the liquid in the gap 14 and is received by the light receiving part 12. The turbidity of the liquid is determined by detecting the transmittance between the light emitting part 11 and the light receiving part 12 and converting the detected transmittance into an electrical signal.

[0031] Reference Figure 1 and Figure 2The cleaning unit comprises a cleaning structure 21 and a limiting structure. In a non-liquid environment, the cleaning structure 21 is located in the gap 14 to avoid the accumulation of external dirt in the gap 14. In a liquid environment, the cleaning structure 21 is separated from the gap 14 to enable the turbidity detection unit 1 to detect the turbidity of the liquid, and the dirt attached to the cleaning part 212 and the dirt near the turbidity detection unit 1 are also taken away from the turbidity detection device when the cleaning part 212 is separated from the turbidity detection unit 1, thereby ensuring the accuracy of the turbidity detection of the turbidity detection device. The limiting structure is used to limit the distance, direction and / or angle of the cleaning structure 21 from the turbidity detection unit 1. When the turbidity detection device is in a non-liquid environment again, the limiting structure can avoid the situation that the cleaning structure 21 cannot return to the gap 14.

[0032] In some embodiments, referring to Figure 1 and Figure 2 , the limiting structure comprises a limiting rod 222, and the limiting rod 222 is arranged at a position corresponding to the opening of the gap 14, so that the cleaning structure 21 is connected with the limiting rod 222. The end of the rod part 211 away from the cleaning part 212 is movably arranged on the limiting rod 222, one end of the limiting rod 222 is provided with an anti-disengagement structure 223, the limiting rod 222 is used to limit the direction of the rod part 211 from the turbidity detection unit 1, and the anti-disengagement structure 223 is used to limit the distance of the rod part 211 from the turbidity detection unit 1, thereby avoiding the situation that the cleaning structure 21 cannot return to the gap 14 when the turbidity detection device is in a non-liquid environment again.

[0033] In some embodiments, referring to Figure 1 and Figure 2 , the turbidity detection device further comprises a mounting seat 3, and the turbidity detection unit 1 and the limiting rod 222 are arranged on the mounting seat 3. For example, the limiting rod 222 is arranged perpendicularly to the mounting seat 3. The structure of the mounting seat 3 is not limited, for example, the mounting seat 3 is in a plate structure, and the turbidity detection device is arranged in the environment where the turbidity needs to be detected through the mounting seat 3. For example, when the turbidity of washing water is detected, the turbidity detection device is arranged at the bottom of the outer tub of the laundry treatment apparatus through the mounting seat 3. The cleaning structure 21 comprises a rod part 211 and a cleaning part 212 arranged on the rod part 211. The structure of the cleaning part 212 is not limited in this embodiment, for example, the cleaning part 212 comprises bristles arranged on the rod part 211.

[0034] The movement of the rod portion 211 on the limiting rod 222 is not limited in the embodiment. In an example (not shown in the figure), a sleeve is arranged on the end of the rod portion 211 away from the cleaning portion 212, the rod portion 211 is sleeved on the limiting rod 222 through the sleeve, the structure of the sleeve is adapted to the structure of the cross section of the limiting rod 222, and the cross section of the rod portion 211 is non-circular. In another example (not shown in the figure), a sliding groove is arranged on the side of the limiting rod 222 close to the rod portion 211, and the sliding groove extends along the length direction of the limiting rod 222. A sliding block is arranged on the end of the rod portion 211 away from the cleaning portion 212, and the sliding block cooperates with the sliding groove. In the above examples, the rod portion 211 can only move along the length direction of the limiting rod 222, and cannot move along the circumferential direction of the limiting rod 222, thereby limiting the direction in which the cleaning structure 21 is separated from the turbidity detection unit 1.

[0035] The anti-separation structure 223 is also not limited in the embodiment. In an example, referring to Figure 1 and Figure 2 , the anti-separation structure 223 is a stopper arranged on the end of the limiting rod 222 away from the mounting seat 3. After the rod portion 211 of the cleaning structure 21 moves to the stopper, the rod portion 211 is blocked by the stopper and cannot continue to move, thereby limiting the distance in which the cleaning structure 21 is separated from the turbidity detection unit 1.

[0036] The turbidity detection device of the embodiment realizes that, in a non-liquid environment, the cleaning structure 21 is located in the gap 14 between the light emitting portion 11 and the light receiving portion 12, and in a liquid environment, the cleaning structure 21 is separated from the gap 14 between the light emitting portion 11 and the light receiving portion 12 in multiple ways.

[0037] In some embodiments, the gravity of the cleaning structure 21 is smaller than the buoyancy of the cleaning structure 21 in a liquid environment of the turbidity detection device. In an example, the density of the entire cleaning structure 21 is smaller than the density of the liquid in the liquid environment in which the cleaning structure 21 is located, for example, the entire cleaning structure 21 can be made of a material with a density smaller than the density of the liquid in the liquid environment in which the turbidity detection device is located. In another example, the structure of the cleaning structure 21 is designed so that the gravity of the cleaning structure 21 is smaller than the buoyancy of the liquid environment in which the cleaning structure 21 is located. For example, the rod portion 211 of the cleaning structure 21 is arranged as a hollow structure, a plurality of through holes are arranged on the peripheral wall of the rod portion 211 to reduce the weight of the rod portion 211, and the cleaning portion 212 is made of a light material. Since the gravity of the cleaning structure 21 is smaller than the buoyancy of the cleaning structure 21 in a liquid environment of the turbidity detection device, in a liquid environment, the entire cleaning structure 21 will float, thereby separating from the gap 14 between the light emitting portion 11 and the light receiving portion 12. In a non-liquid environment, the entire cleaning structure 21 will return to the gap 14 between the light emitting portion 11 and the light receiving portion 12 due to gravity.

[0038] In some embodiments, the turbidity detection device further comprises a power structure connected with the cleaning structure 21. In a liquid environment, the power structure drives the cleaning structure 21 to be separated from the gap 14 between the light emitting part 11 and the light receiving part 12. In an example (not shown in the figure), the power structure is a telescopic member arranged on the mounting seat 3, and the telescopic member is connected with the rod part 211 of the cleaning structure 21. In a non-liquid environment, the telescopic member can be controlled to be in a contracted state so that the cleaning part 212 is located in the gap 14 between the light emitting part 11 and the light receiving part 12. In a liquid environment, the telescopic member can be controlled to be in an extended state so that the cleaning part 212 is separated from the gap 14 between the light emitting part 11 and the light receiving part 12. In another example, referring to Figure 1 and Figure 2 Figure 1 Figure 2 The power structure comprises a floating part, and the density of the floating part is less than the density of the liquid in the liquid environment where the turbidity detection device is located. For example, the floating part comprises at least one floating ball 23 arranged at the end of the rod part 211 close to the cleaning part 212. For example, when the limiting structure is the limiting fulcrum 221, one floating ball 23 is arranged at the end of the rod part 211 close to the cleaning part 212. Alternatively, when the limiting structure is the limiting rod 222, a plurality of floating balls 23 are arranged on the rod part 211.

[0039] According to an exemplary embodiment, the present embodiment provides a laundry treatment apparatus, and the laundry treatment apparatus has a washing function and can be a washing machine or a washer-dryer. The laundry treatment apparatus comprises an outer tub, and the tub bottom of the outer tub is provided with a turbidity detection device as proposed in the above-mentioned embodiments. In the laundry treatment apparatus of the present embodiment, when the outer tub is in a waterless state, the cleaning structure 21 is located in the gap 14 between the light emitting part 11 and the light receiving part 12, and dirt is not easy to accumulate in the gap 14 between the light emitting part 11 and the light receiving part 12 of the turbidity detection device. When the outer tub is in a water-filled state, the cleaning structure 21 is separated from the gap 14 between the light emitting part 11 and the light receiving part 12, so that the turbidity detection unit 1 detects the turbidity of the liquid, and at the same time, the dirt attached to the cleaning structure 21 and the dirt located near the turbidity detection unit 1 are also taken away from the turbidity detection device when the cleaning structure 21 is separated from the turbidity detection unit 1, thereby ensuring the accuracy of the turbidity detection of the turbidity detection device, and further accurately judging the washing effect of the laundry and improving the user experience.
