Description

Technical Field

[0001] This invention relates to the field of clothing processing equipment, and more particularly to a clothing processing device and control method. Background Technology

[0002] Currently, there are garment cleaning devices that determine the cleaning effect of clothes by detecting the turbidity of the water inside the garment, thus providing users with a better experience. The turbidity detection device measures the water's light transmittance and then uses a photoresistor to measure the voltage, thereby detecting the turbidity of the water.

[0003] In related technologies, turbidity detection devices are located near the drain outlet. However, being in a constantly wet environment, these devices easily accumulate dirt and grime, affecting the accuracy of turbidity measurements. Furthermore, because the device is near the drain outlet, residual wastewater from the drain pump can enter the drain, causing the turbidity value detected by the device to differ from the actual turbidity value of the water inside the laundry processing equipment. This can affect the equipment's assessment of the washing effect, thus impacting the washing performance. Additionally, to avoid the influence of foam on turbidity detection accuracy, the laundry processing equipment needs to be allowed to settle for a period before testing, increasing the total processing time. Uneven distribution of dirt and grime in the water within the equipment can also affect the test results. Summary of the Invention

[0009] Further optionally, the mounting structure includes a partition disposed on the inner wall of the outer cylinder, and a funnel-shaped receiving cavity with a wide top and a narrow bottom is formed between the partition and the inner wall of the outer cylinder.

[0010] Further optionally, a first filter structure is provided on the top of the mounting structure and / or a second filter structure is provided inside the mounting structure, the second filter structure being located between the turbidity detection device and the top of the mounting structure.

[0011] The second aspect of the present invention provides a control method for a garment processing device, the control method being applied to the garment processing device as described in the first aspect of the invention;

[0012] The garment processing equipment is equipped with a first turbidity detection program, which is used to detect the turbidity of the water inside the outer drum; the control method includes:

[0013] When the clothing processing equipment runs to the point where the first set condition of the first turbidity detection program is met, the rotation speed of the inner drum of the clothing processing equipment is increased to the set speed, and the turbidity detection device is controlled to detect the turbidity value of the water in the outer drum.

[0014] Further optionally, the first setting condition includes: the washing time of the garment processing device in the washing stage reaches the set washing time, or the number of rinsing cycles of the garment processing device in the rinsing stage reaches the set number of rinsing cycles.

[0015] Further optionally, the garment processing device includes a first judgment program and a second judgment program; the first judgment program is used to determine whether the turbidity value of the water in the outer drum is greater than or equal to a set turbidity value; the second judgment program is used to determine whether the number of turbidity detections is greater than a set number; after the first turbidity detection program ends, the control method includes:

[0016] Obtain the turbidity value of the water inside the outer cylinder;

[0017] Execute the first judgment procedure;

[0018] Under the first judgment procedure, if the turbidity value of the water in the outer drum is greater than or equal to the set turbidity value, the clothing processing process continues; if the turbidity value of the water in the outer drum is less than the set turbidity value, the second judgment procedure is executed.

[0019] Further optionally, under the second judgment procedure, when the number of turbidity detections is greater than the set number, the turbidity detection is stopped and the clothing processing process continues until the set end condition is met; when the number of turbidity detections is less than or equal to the set number, the inner drum is controlled to stop rotating for a set time and then the first turbidity detection procedure is executed again.

[0020] Further optionally, the garment processing equipment includes a third judgment procedure, which is used to determine whether the first initial turbidity value detected by the turbidity detection device before the outer drum is filled with water and the second initial turbidity value detected after the outer drum is filled with water meet a second set condition; before executing the first turbidity detection procedure, the control method further includes:

[0021] Before water begins to enter the outer cylinder, the first initial turbidity value detected by the turbidity detection device is obtained;

[0022] After the outer drum finishes filling with water, the inner drum is controlled to rotate at a washing speed to obtain the second initial turbidity value detected by the turbidity detection device. The washing speed is less than the set speed.

[0023] Execute the third judgment procedure;

[0024] Under the third judgment procedure, when the first initial turbidity value and the second initial turbidity value meet the second set condition, the clothing processing equipment is controlled to run to the first set condition of executing the first turbidity detection procedure; when the first initial turbidity value and the second initial turbidity value do not meet the second set condition, the second judgment procedure is executed.

[0026] Further optionally, the second setting condition is: the absolute value of the difference between the first initial turbidity value and the second initial turbidity value is less than or equal to a set difference.

[0027] The technical solution of this invention can include the following beneficial effects: This invention places the turbidity detection device on the inner wall of the outer drum above the highest inlet water level. When it is necessary to detect the turbidity of the water in the outer drum, the rotation speed of the inner drum is increased. The high-speed rotation of the inner drum causes water in the outer drum to splash towards the location of the turbidity detection device, thereby achieving the detection of the turbidity of the water in the outer drum. When it is not necessary to detect the turbidity of the water in the outer drum, the turbidity detection device is separated from the water in the outer drum, which can effectively reduce the degree of dirt adhering to the turbidity detection device, improve the accuracy of turbidity detection, and improve the accuracy of judging the degree of cleanliness. At the same time, the clothing processing equipment does not need to be stationary during the turbidity detection process, thus not increasing the processing time. Furthermore, increasing the inner drum rotation speed prevents uneven distribution of dirt in the water during turbidity detection, ensuring the accuracy of the detection results.

Detailed Implementation

[0036] 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.

[0037] In related technologies, turbidity detection devices are located near the drain outlet. However, being in a constantly wet environment, these devices easily accumulate dirt and grime, affecting the accuracy of turbidity measurements. Furthermore, because the device is near the drain outlet, residual wastewater from the drain pump can enter the drain, causing the turbidity value detected by the device to differ from the actual turbidity value of the water inside the laundry processing equipment. This can affect the equipment's assessment of the washing effect, thus impacting the washing performance. Additionally, to avoid the influence of foam on turbidity detection accuracy, the laundry processing equipment needs to be allowed to settle for a period before testing, increasing the total processing time. Uneven distribution of dirt and grime in the water within the equipment can also affect the test results.

[0038] To address the aforementioned technical problems, this embodiment proposes a garment processing device. The device includes an outer drum and a turbidity detection device. The turbidity detection device is mounted on the inner wall of the outer drum, positioned above the highest inlet water level. This embodiment achieves this by positioning the turbidity detection device above the highest inlet water level on the inner wall of the outer drum, and by increasing the rotational speed of the inner drum when turbidity detection is needed. The high-speed rotation of the inner drum causes water inside the outer drum to splash towards the turbidity detection device.

[0039] This allows for the detection of turbidity in the water inside the outer cylinder. When turbidity detection is not required, the turbidity detection device is separated from the water inside the outer cylinder, effectively reducing the amount of dirt adhering to the turbidity detection device.

[0040] This improves the accuracy of turbidity detection and the accuracy of judging the degree of cleanliness. Furthermore, the garment processing equipment does not require static placement during turbidity detection, thus not increasing processing time, and the detection speed is increased after the inner drum rotates.

[0041] Turbidity measurements do not suffer from uneven distribution of contaminants in the water, ensuring the accuracy of the test results. The technical solution of this embodiment is described in detail below. Where there is no conflict, the following embodiments and implementation methods can be combined with each other.

[0042] According to an exemplary embodiment, this embodiment provides a clothing processing device. This clothing processing device has a clothing washing function and can be a clothing processing device with a separate washing function.

[0043] For example, a washing machine can also be a garment processing device that combines one of the functions of drying and garment care, such as a washer-dryer combo. The garment processing device in this embodiment can be either a top-loading or a front-loading garment processing device.

[0044] The garment processing device of this embodiment includes an outer drum 1, which is the water-holding drum of the garment processing device. A rotatable inner drum 2 is disposed inside the outer drum 1, which is the washing drum of the garment processing device.

[0045] The drum wall is equipped with multiple flow holes. During the washing process, water from the outer drum flows into the inner drum 2 through these holes, and water from the inner drum 2 flows into the outer drum 1 through the same holes. The clothing processing equipment also includes...

[0046] The turbidity detection device 3 is used to detect the turbidity of the water inside the outer cylinder 1. The turbidity detection device 3 is installed on the inner wall of the outer cylinder 1, and its position is higher than the highest water inlet level 4 of the outer cylinder 1 to prevent it from being submerged after water enters the outer cylinder 1. In this embodiment, the installation method of the turbidity detection device 3 on the outer cylinder 1 is not limited, but at least the detection end 31 of the turbidity detection device 3 must be located inside the outer cylinder 51.

[0047] It should be noted that the turbidity detection device 3 in this embodiment should be positioned higher than the highest position that the water in the outer drum 1 can reach when the inner drum 2 is at the washing speed during the washing stage or the rinsing speed during the rinsing stage, so as to prevent the washing water or rinsing water from wetting the turbidity detection device 3 when turbidity detection is not required during the washing or rinsing stage.

[0048] This embodiment does not limit the structure of the turbidity detection device. In one example, refer to... Figure 3 and Figure 4 As shown, the turbidity detection device includes a turbidity detection body 311. A light emitting part 312 and a light receiving part 313 are disposed on the turbidity detection body 311, with the light emitting part 312 and the light receiving part 313 positioned opposite each other and separated by a gap. The turbidity detection body 311 is mounted on the inner wall of an outer cylinder, and the light emitting part 312 and the light receiving part 313 are located inside the outer cylinder. In a liquid environment, liquid enters the gap between the light emitting part 312 and the light receiving part 313. The light emitted by the light emitting part 312 passes through the liquid in the gap and is received by the light receiving part 313. The turbidity of the liquid is determined by detecting the transmittance between the light emitting part 312 and the light receiving part 313 and converting the detected transmittance into an electrical signal.

[0049] In some embodiments, an installation structure 5 is provided on the inner wall of the outer cylinder 1, and a receiving cavity 54 is provided inside the installation structure 5. Water passage holes are respectively provided at the top and bottom of the installation structure 5, and the water passage holes communicate with the receiving cavity 54. The detection end 31 of the turbidity detection device 3 is housed in the receiving cavity 54, thereby further preventing the turbidity detection device 3 from being wetted by the water in the outer cylinder 1 when turbidity detection is not required. The water passage holes provided at the top and bottom of the installation structure 5 ensure that when turbidity detection is required, water in the outer cylinder 1 enters into the receiving cavity 54 and flows out of the receiving cavity 54, which can realize the detection of water turbidity by the turbidity detection device 3 and prevent water from remaining in the receiving cavity 54.

[0050] This embodiment does not limit the structure of the installation structure 5. For example, Figure 2 As shown, the installation structure 5 includes a partition disposed on the inner wall of the outer cylinder 1, forming a funnel-shaped receiving cavity that is wide at the top and narrow at the bottom between the partition and the inner wall of the outer cylinder 1. A bottom water passage hole 53 is provided at the lowest position of the funnel-shaped receiving cavity, and a top water passage hole (not shown in the figure) is provided at the top of the funnel-shaped receiving cavity. By setting the receiving cavity 54 in a funnel shape, the water in the outer cylinder 1 does not flow out of the receiving cavity 54 quickly after entering the funnel-shaped receiving cavity, thus providing sufficient water volume for turbidity detection. At the same time, it prevents water from flowing out of the receiving cavity 54 when the turbidity detection device 3 fails to detect turbidity, ensuring the accuracy of the detection by the turbidity detection device 3.

[0051] The mounting structure 5 in this embodiment can also be other structures, such as a hemispherical structure, a rectangular structure, etc., which will not be listed here. The accommodating cavity 54 and the inner wall of the outer cylinder 1 can be integrally formed, or it can be set independently of the inner wall of the outer cylinder 1 and set on the inner wall of the outer cylinder 1 by means of snap-fit, plug-in, connector or welding.

[0052] In some embodiments, a first filter structure 51 is provided on the top of the mounting structure 5. The first filter structure 51 is, for example, a first filter screen. The provision of the first filter structure 51 can prevent dirt inside the outer cylinder 1 from entering the receiving cavity 54.

[0053] In some embodiments, a second filter structure 52 is disposed inside the mounting structure 5, located between the turbidity detection device 3 and the top of the mounting structure 5. The second filter structure 52 is, for example, a second filter screen, the mesh size of which is smaller than that of the first filter screen. The provision of the second filter structure 52 can further prevent fine dirt entering the receiving cavity 54 from adhering to the detection end 31 of the turbidity detection device 3.

[0054] According to an exemplary embodiment, this embodiment proposes a control method for a garment processing device, which is applied to the garment processing device described in the above embodiment. The garment processing device of this embodiment includes a first turbidity detection program for detecting the turbidity of the water inside the outer drum. The control method of this embodiment includes: when the garment processing device operates to a point where a first set condition of the first turbidity detection program is met, controlling the rotational speed of the inner drum of the garment processing device to increase to a set rotational speed, and controlling a turbidity detection device to detect the turbidity value of the water inside the outer drum. The set rotational speed is the minimum rotational speed at which the inner drum drives the water inside the outer drum to the position of the turbidity detection device. For example, the set rotational speed is 80 rpm to 100 rpm.

[0055] In some embodiments, the first set condition includes: the washing time of the garment handling device in the washing stage reaches the set washing time, or the number of rinsing cycles in the rinsing stage reaches the set number of rinsing cycles. When the washing stage reaches the set washing time, the turbidity of the water in the outer drum is determined by executing a first turbidity detection program, thereby determining the degree of garment cleanliness. When the turbidity value of the water in the outer drum no longer increases or the turbidity value of the water in the outer drum is not higher than the set washing turbidity value, it indicates that the garment has reached the optimal degree of cleanliness, and washing can be stopped at this time; when the turbidity value of the water in the outer drum continues to rise or the turbidity value of the water in the outer drum is higher than the set washing turbidity value, it indicates that the garment has not yet reached the optimal degree of cleanliness, and washing needs to continue. When the rinsing stage reaches the set number of rinsing cycles, the turbidity of the water in the outer drum is determined by executing the first turbidity detection program, thereby determining the degree of garment cleanliness. When the turbidity value of the water in the outer drum no longer increases or does not exceed the set turbidity value for rinsing, it means that the clothes have reached the optimal level of rinsing, and rinsing can be stopped at this time. When the turbidity value of the water in the outer drum continues to rise or exceeds the set turbidity value for rinsing, it means that the clothes have not yet reached the optimal level of rinsing, and rinsing needs to continue.

[0056] This embodiment increases the rotation speed of the inner drum to a set speed. The high-speed rotation of the inner drum causes water in the outer drum to splash towards the turbidity detection device, thus detecting the turbidity of the water in the outer drum. When it's not necessary to detect the turbidity of the water in the outer drum, the turbidity detection device separates from the water in the outer drum, effectively reducing the amount of dirt adhering to the device and improving the accuracy of turbidity detection, thereby improving the accuracy of the washing cleanliness assessment. Simultaneously, the garment processing equipment does not need to be stationary during turbidity detection, thus not increasing the garment processing time. Furthermore, increasing the inner drum's rotation speed prevents uneven distribution of dirt in the water, ensuring the accuracy of the detection results.

[0057] According to an exemplary embodiment, the clothing processing device of this embodiment includes a first judgment program and a second judgment program. The first judgment program is used to determine whether the turbidity value of the water in the outer drum is greater than or equal to a set turbidity value; the second judgment program is used to determine whether the number of turbidity detections is greater than a set number. Figure 5 A control flowchart of a garment processing device according to an exemplary embodiment of the present invention is shown, with reference to... Figure 5 After the first turbidity detection procedure is completed, the control method includes the following steps:

[0058] S51, obtain the turbidity value of the water inside the outer cylinder;

[0059] S52, execute the first judgment procedure;

[0060] S53, under the first judgment procedure, if the turbidity value of the water in the outer drum is greater than or equal to the set turbidity value, the clothing processing process continues; if the turbidity value of the water in the outer drum is less than the set turbidity value, the second judgment procedure is executed.

[0061] In this embodiment, after executing the first turbidity detection procedure, it is necessary to obtain the turbidity of the water inside the outer cylinder detected by the turbidity detection device, and execute the first judgment procedure to determine whether there is a turbidity detection malfunction. The turbidity value is set to be slightly greater than the detection value of clean water. If the turbidity value of the water inside the outer cylinder is greater than or equal to the set turbidity value, this is normal, and the clothing processing process can continue. If the turbidity value of the water inside the outer cylinder is less than the set turbidity value, a turbidity detection malfunction may occur. The causes of a turbidity detection malfunction include: excessive foam inside the outer cylinder, or a blocked filter structure on the installation structure, etc. In this case, the second judgment procedure is executed to further determine whether there is a turbidity detection malfunction.

[0062] In some embodiments, under the second judgment procedure, when the number of turbidity detections is less than or equal to a set number, the inner drum is stopped rotating for a set time, and the first turbidity detection procedure is executed again. After completing the first turbidity detection procedure, the first judgment procedure is executed again to further determine whether a turbidity detection fault exists. When the number of turbidity detections exceeds the set number, a turbidity detection fault is determined, turbidity detection is stopped, and the clothing processing process continues until a set end condition is reached. The set end condition is, for example, the clothing processing process reaching its end time, at which point the clothing processing process ends; or, the clothing processing equipment displays a fault indication, at which point the clothing processing process is stopped. After the set end condition is reached, the clothing processing equipment also issues a turbidity detection fault indication message to the user. In this embodiment, the set number of detections is, for example, 3 times, and the set time is, for example, 5 seconds.

[0063] According to an exemplary embodiment, the garment processing device includes a third judgment procedure, which is used to determine whether a first initial turbidity value detected by the turbidity detection device before the outer drum is filled with water and a second initial turbidity value detected after the outer drum is filled with water meet a second set condition. Figure 6 A control flowchart of a garment processing device according to an exemplary embodiment of the present invention is shown, with reference to... Figure 6 Before performing the first turbidity detection procedure, the control method also includes:

[0064] S61, before the outer cylinder starts to be filled with water, obtain the first initial turbidity value detected by the turbidity detection device;

[0065] S62, after the outer drum finishes water intake, control the inner drum to rotate at the washing speed to obtain the second initial turbidity value detected by the turbidity detection device, and the washing speed is less than the set speed;

[0066] S63, execute the third judgment procedure;

[0067] S64, under the third judgment procedure, when the first initial turbidity value and the second initial turbidity value meet the second set condition, the clothing processing equipment is controlled to run to the first set condition for executing the first turbidity detection procedure; when the first initial turbidity value and the second initial turbidity value do not meet the second set condition, the second judgment procedure is executed.

[0068] In this embodiment, to improve the accuracy of turbidity detection, the turbidity detection device needs to detect the turbidity inside the outer drum before water begins to enter. Since there is no water in the outer drum at this time, the turbidity detected by the turbidity detection device is the turbidity under empty drum conditions, and the turbidity value at this time is determined to be the first initial turbidity value. After the water enters the outer drum, the laundry processing equipment starts washing clothes, and the inner drum rotates at a washing speed lower than the set speed, for example, 50 rpm. Since the inner drum rotates at a low speed at this time, it cannot carry the water in the outer drum to the position set by the turbidity detection device during the rotation of the inner drum. Therefore, the turbidity value detected by the turbidity detection device at this time should theoretically be close to the first initial turbidity value, and the turbidity value at this time is determined to be the second initial turbidity value. After obtaining the first turbidity value and the second turbidity value, a third judgment procedure needs to be executed to determine whether there is a turbidity detection fault. The third judgment procedure judges whether the first turbidity value and the second turbidity value meet the second set condition. The second set condition is used to determine whether the deviation between the second initial value and the first initial value is within the theoretical range. For example, the second setting condition is: the absolute value of the difference between the first initial turbidity value and the second initial turbidity value is less than or equal to a set difference, which is the maximum deviation of the turbidity detection device and is related to the model of the turbidity detection device.

[0069] In the third judgment procedure, when the first initial turbidity value and the second initial turbidity value meet the second set condition, it indicates that the deviation between the second initial value and the first initial value is within the theoretical range, which is normal. The washing machine continues to run until the first set condition for executing the first turbidity detection program is met, and then executes the first turbidity detection program. When the first initial turbidity value and the second initial turbidity value do not meet the second set condition, it indicates that the deviation between the second initial value and the first initial value is not within the theoretical range, and the turbidity detection may be malfunctioning. The reasons for turbidity detection errors include: excessive water in the outer drum, such as a problem with the liquid level sensor; abnormal motor speed causing the inner drum to rotate too fast, such as a problem with the main control or drive; or a malfunction in the turbidity detection device itself. Therefore, the second judgment procedure needs to be executed to further determine whether a turbidity detection malfunction has occurred.

[0070] In some embodiments, under the second judgment procedure, when the number of turbidity detections is less than or equal to a set number, the inner drum is controlled to stop rotating for a set time before acquiring the second initial turbidity value again, and a third judgment procedure is executed to further determine whether a turbidity detection fault exists. When the number of turbidity detections exceeds the set number, a turbidity detection fault is determined to exist. At this time, turbidity detection is stopped, and the clothing processing process continues until a set end condition is reached. The set end condition is, for example, the clothing processing process reaching its end time, at which point the clothing processing process ends; or, the clothing processing equipment displays a fault indication, at which point the clothing processing process is stopped, and a turbidity detection fault indication message is sent to the user after the set end condition is reached. In this case, even if the clothing processing process reaches the set condition for executing the first turbidity detection procedure, the first detection procedure will not be performed again. In this embodiment, the set time is, for example, 5 seconds, and the set number of times is, for example, 3 times.

[0071] The control method of this embodiment will be described in detail below with reference to a specific example. Figure 7 The control flowchart and control method include the following steps:

[0072] S71, the garment processing equipment starts running, proceed to S72;

[0073] S72, before the outer cylinder starts to be filled with water, obtain the first initial turbidity value A detected by the turbidity detection device, and proceed to S73;
