Detailed Embodiments

[0032] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0033] In the related art, the turbidity of a liquid is detected by placing a turbidity detection device in a liquid environment. However, since the turbidity detection device is immersed in the liquid environment for a long time or frequently, it is easy for dirt in the liquid to accumulate on and near the turbidity detection device, thus seriously affecting the accuracy of turbidity detection of the turbidity detection device.

[0034] To solve the above technical problems, this embodiment proposes a turbidity detection device. The turbidity detection device includes a turbidity detection unit and a cleaning unit. The cleaning unit includes a cleaning structure and a limiting structure, and the cleaning structure is connected to the limiting structure. In a non-liquid environment, the cleaning structure is located in the gap between the light emitting part and the light receiving part. In a liquid environment, the cleaning structure disengages from the gap between the light emitting part and the light receiving part. The limiting structure is used to define the distance, direction, and / or angle at which the cleaning structure disengages from the turbidity detection unit. In the non-liquid environment of the turbidity detection device of this embodiment, the cleaning part is located in the gap between the light emitting part and the light receiving part, and dirt is not easily accumulated between the light emitting part and the light receiving part, but accumulates on the cleaning structure. In a liquid environment, the cleaning structure disengages from the gap between the light emitting part and the light receiving part to detect the turbidity of the liquid. At the same time, the dirt attached to the cleaning structure and the dirt near the turbidity detection unit are also carried away from the turbidity detection unit when the cleaning structure disengages from the turbidity detection unit, and the turbidity detection result is more accurate.

[0035] The technical solutions of this embodiment will be elaborated in detail below with reference to the accompanying drawings. Without conflict, the following embodiments and implementations can be combined with each other.

[0036] According to an exemplary embodiment, this embodiment proposes a turbidity detection device. The turbidity detection device of this embodiment can be applied to any scenario that requires turbidity detection. For example, by detecting the turbidity of washing water to determine the washing effect of clothes, by detecting the turbidity of water quality to determine the water pollution situation, and also by detecting the turbidity of a liquid for related laboratory analysis tests. The turbidity detection device of this embodiment detects the turbidity of a liquid substance, and the liquid substance can be water.

[0037] As Figures 1-6 shown, the turbidity detection device of this embodiment includes a turbidity detection unit 1. Refer to Figure 6, the turbidity detection unit 1 includes a turbidity detection body 11, a light emitting part 11 and a light receiving part 12 located on the turbidity detection body 11. 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, the 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. By detecting the light transmittance between the light emitting part 11 and the light receiving part 12 and converting the detected light transmittance into an electrical signal, the turbidity of the liquid is judged.

[0038] Referring to Figures 1-5 , the cleaning unit includes a cleaning structure 21 and a limiting structure, and the cleaning structure 21 is connected to the limiting structure. In a non-liquid environment, the cleaning structure 21 is located in the gap 14 to prevent external dirt from accumulating in the gap 14. In a liquid environment, the cleaning structure 21 disengages from the gap 14 so that the turbidity detection unit 1 can detect the turbidity of the liquid. At the same time, the dirt attached to the cleaning part 212 when the cleaning part 212 disengages from the turbidity detection unit 1 and the dirt near the turbidity detection unit 1 are also carried away from the turbidity detection device, 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 at which the cleaning structure 21 disengages from the turbidity detection unit 1. When the turbidity detection device returns to a non-liquid environment again, the limiting structure can prevent the situation where the cleaning structure 21 cannot return to the gap 14.

[0039] According to an exemplary embodiment, referring to Figures 1-5 , the turbidity detection device includes a mounting base 3, and the turbidity detection unit 1 is arranged on the mounting base 3. The structure of the mounting base 3 is not limited. For example, the mounting base 3 has a plate-like structure, and the turbidity detection device is arranged in the environment where the turbidity needs to be detected through the mounting base 3. For example, when detecting the turbidity of washing water, the turbidity detection device is arranged at the bottom of the outer tub of the laundry treatment device through the mounting base 3. The cleaning structure 21 includes a rod part 211 and a cleaning part 212 arranged on the rod part 211. The structure of the cleaning part 212 in this embodiment is not limited. For example, the cleaning part 212 includes bristles arranged on the rod part 211. There are various ways of cooperation between the cleaning structure 21 and the limiting structure in this embodiment.

[0040] In some embodiments, referring to Figure 1 and Figure 2, the limiting structure includes a limiting fulcrum 221. The limiting fulcrum 221 is provided on the mounting base 3, and the position of the limiting fulcrum 221 on the mounting base 3 corresponds to the opening of the gap 14, so that the cleaning structure 21 is connected to the fulcrum. One end of the rod portion 211 away from the cleaning portion 212 is hinged to the limiting fulcrum 221. The hinging height of the rod portion 221 on the limiting fulcrum 221 is approximately equal to the height of the turbidity detection body 11 on the mounting base 3, so that the rod portion 211 is arranged in the gap 14 in a posture parallel to the turbidity detection body 13 in a non-liquid environment. The limiting fulcrum 221 is used to limit the angle and direction of the rod portion 211 departing from the turbidity detection unit 1.

[0041] Exemplarily, referring to Figure 3 , the limiting fulcrum 221 includes a first portion 2211 and a second portion 2212. The first portion 2211 is provided on the mounting base 3, and the second portion 2212 is provided at one end of the first portion 2211 away from the turbidity detection unit 1. One end of the rod portion 211 away from the cleaning portion 212 is hinged at the position where the first portion 2211 and the second portion 2212 are connected. In a liquid environment, after the cleaning portion 212 departs from the gap 14, one end of the rod portion 211 away from the cleaning portion 212 rotates around the limiting fulcrum 221, thereby limiting the direction of the cleaning structure 21 departing from the turbidity detection unit 1. When the rod portion 211 rotates to the second portion 2212, it is blocked by the second portion 2212 and cannot continue to rotate, thereby limiting the angle of the cleaning structure 21 departing from the turbidity detection unit 1. Moreover, a preset included angle is formed between the first portion 2211 and the second portion 2212, and the preset included angle is less than or equal to 90 degrees. For example, the preset included angle is 30 degrees, to avoid the situation that when the turbidity detection device returns to a non-liquid environment again, the cleaning structure 21 cannot return to the gap 14.

[0042] Exemplarily (not shown in this example figure), a first limiting groove is provided on the side of the first portion 2211 away from the mounting base 3, and a second limiting groove is provided on the side of the second portion 2212 close to the turbidity detection unit 1. The first limiting groove communicates with the second limiting groove. One end of the rod portion 211 away from the cleaning portion 212 is hinged at the position where the first limiting groove and the second limiting groove communicate. In this embodiment, by providing the first limiting groove on the first portion 2211 and the second limiting groove on the second portion 2212, the assembly reliability between one end of the rod portion 211 away from the cleaning structure 21 and the limiting fulcrum 221 can be achieved.

[0043] In some embodiments, referring to Figure 4 and Figure 5, the limiting structure includes a limiting rod 222, which is arranged on the mounting base 3. Exemplarily, the limiting rod 222 is arranged perpendicular to the mounting base 3. The position of the limiting rod 222 arranged on the mounting base 3 corresponds to the opening of the gap 14, so that the cleaning structure 21 is connected to the limit. One end of the rod portion 211 away from the cleaning portion 212 is movably arranged on the limiting rod 222. An anti-disengagement structure 223 is arranged at one end of the limiting rod 222 away from the mounting base 3. The limiting rod 222 is used to limit the direction in which the rod portion 211 disengages from the turbidity detection unit 1, and the anti-disengagement structure 223 is used to limit the distance in which the rod portion 211 disengages from the turbidity detection unit 1, so as to avoid the situation where the cleaning structure 21 cannot return to the gap 14 when the turbidity detection device is in a non-liquid environment again.

[0044] This embodiment does not limit the moving manner of the rod portion 211 on the limiting rod 222. In one example (not shown in the figure of this example), a collar is arranged at one 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 collar. The structure of the collar 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 of this example), a sliding groove is arranged on one 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.

[0045] In the above examples, the rod portion 211 can only move along the length direction of the limiting rod 222, but cannot move along the circumferential direction of the limiting rod 222, thereby limiting the direction in which the cleaning structure 21 disengages from the turbidity detection unit 1.

[0046] This embodiment does not limit the anti-disengagement structure 223 either. In one example, referring to Figure 4 and Figure 5 , the anti-disengagement structure 223 is a stop block arranged at one end of the limiting rod 222 away from the mounting base 3. When the rod portion 211 of the cleaning structure 21 moves to the stop block, it is blocked by the stop block and cannot move further, thereby limiting the distance in which the cleaning structure 21 disengages from the turbidity detection unit 1.

[0047] In this embodiment, the turbidity detection device realizes that in a non-liquid environment, the cleaning structure 21 is located in the gap 14 between the light emitting part 11 and the light receiving part 12. In a liquid environment, there are various ways for the cleaning structure 21 to disengage from the gap 14 between the light emitting part 11 and the light receiving part 12.

[0048] In some embodiments, the gravity of the cleaning structure 21 is less than the buoyancy force received by the cleaning structure 21 when the turbidity detection device is in a liquid environment. In one example, the overall density of the cleaning structure 21 is less than that of the liquid environment where it is located.

[0049] In some embodiments, the gravity of the cleaning structure 21 is less than the buoyancy force received by the cleaning structure 21 when the turbidity detection device is in a liquid environment. In one example, the overall density of the cleaning structure 21 is less than that of the liquid environment where it is located.

[0050] The density of the liquid in the liquid environment. For example, the entire cleaning structure 21 can be made of a material with a density less than that of the liquid in the liquid environment where the turbidity detection device is located. In another example, by designing the structure of the cleaning structure 21, the gravity of the cleaning structure 21 can be made less than the buoyancy of its liquid environment.

[0051] For example, the rod portion 211 of the cleaning structure 21 is set as a hollow structure, and a number of through holes are opened 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 lightweight material.

[0052] Since the gravity of the cleaning structure 21 is less than the buoyancy force that the cleaning structure 21 receives in the liquid environment of the turbidity detection device, in the liquid environment, the entire cleaning structure 21 will float upward, thus disengaging 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.

[0053] In some embodiments, the turbidity detection device further includes a power structure, and the power structure is connected to the cleaning structure 21. In the liquid environment, the power structure drives the cleaning structure 21 to disengage from the gap 14 between the light emitting portion 11 and the light receiving portion 12. In one example (not shown in the figure of this example), the power structure is a telescopic member provided on the mounting base 3, and the telescopic member is connected to the rod portion 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 portion 212 is located in the gap 14 between the light emitting portion 11 and the light receiving portion 12. In the liquid environment, the telescopic member can be controlled to be in a stretched state so that the cleaning portion 212 disengages from the gap 14 between the light emitting portion 11 and the light receiving portion 12. In another example, referring to Figure 1 and Figure 2 , Figure 4 and Figure 5 , the power structure includes a floating portion, and the density of the floating portion is less than the density of the liquid in the liquid environment where the turbidity

[0054] detection device is located. Exemplarily, the floating portion includes at least a floating ball 23 provided at one end of the rod portion 211 close to the cleaning portion 212. For example, when the limiting structure is the limiting fulcrum 221

[0055] a floating ball 23 is provided at one end of the rod portion 211 close to the cleaning portion 212. Or, when the limiting structure is the limiting rod 222, a plurality of floating balls 23 are provided on the rod portion 211.

[0056] According to an exemplary embodiment, this embodiment provides a laundry treatment device. The laundry treatment device of this embodiment has a washing function, and the laundry treatment device can be a washing machine or a washer-dryer. 0 The laundry treatment device of this embodiment includes an outer tub, and a turbidity detection device as proposed in the above embodiment is provided at the bottom of the outer tub. When there is no water in the outer tub of the laundry treatment device of this embodiment, the cleaning structure 21 is located in the gap 14 in front of the light emitting part 11 and the light receiving part 12, and dirt is not likely to accumulate in the gap 14 in front of the light emitting part 11 and the light receiving part 12 of the turbidity detection device.

[0057] When water enters the outer tub, the cleaning structure 21 disengages from the gap 14 in front of the light emitting part 11 and the light receiving part 12, so that the turbidity detection unit 1 can detect the turbidity of the liquid. At the same time, when the cleaning structure 21 disengages from the turbidity detection unit 1, the dirt attached to the cleaning structure 21 and the dirt near the turbidity detection unit 1 are also carried away from the turbidity detection device, thus ensuring the accuracy of the turbidity detection of the turbidity detection device, and further being able to accurately judge the washing effect of the clothes and improving the user experience.
