Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, specifically relating to a garment processing device, a drying control method, and a storage medium. Background Technology

[0002] In a condenser washer-dryer, hot dry air is introduced into the clothes handling drum during the drying process to exchange heat with the damp load. This removes moisture from the load, creating humid air. The humid air then enters the condenser's pipes to exchange heat with the cooling water. The water vapor in the humid air condenses into water and mixes with the existing cooling water in the condenser to form condensate.

[0003] A related technology provides a drying determination scheme for a condenser washer-dryer combo. During the drying process, the condensate in the condenser is discharged into the outer drum. When the water level of the condensate submerges the temperature sensor in the outer drum, the temperature sensor is used to detect the temperature of the condensate. The drying determination is based on the temperature of the condensate and the air inlet temperature of the clothes processing drum.

[0004] However, after the condensate drains from the outer cylinder, it accumulates at the very bottom of the outer cylinder. Only when the water level rises can it submerge the temperature sensor. During this process, the temperature of the condensate will drop. Therefore, there is a large difference between the temperature detected by the temperature sensor and the actual temperature of the condensate in the condenser. The accuracy of judging dryness based on the temperature of the condensate detected by the temperature sensor is not high. Summary of the Invention

[0019] In some embodiments of this application, the width of the first guide channel near the perforation end is greater than the width of the first guide channel near the temperature sensor end.

[0051] Exemplary embodiments of this application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of this application and to fully convey the scope of this application to those skilled in the art.

[0052] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this application pertains.

[0053] A condenser washer-dryer combo is equipped with a heating device and a condenser. The heating device heats the cold air entering the air duct to form dry hot air. The dry hot air is then passed into the clothes handling drum, where it exchanges heat with the damp load and removes the moisture from the load, forming humid hot air. The humid hot air then enters the condenser's pipes and exchanges heat with cooler water. The water vapor in the humid hot air condenses into condensate, and the humid hot air becomes dry cold air again. This cold air is then heated back into dry hot air by the heating device, and the cycle continues in this way, removing the moisture from the load and thus drying it.

[0054] In condenser washer-dryer combos, the temperature inside the clothes drying drum can reach high levels, sometimes even 100°C, which may damage the clothes. Furthermore, the rotation of the drum and the stacking of clothes can lead to uneven temperatures across the load. If the drying time is determined by measuring the inlet and outlet air temperatures of the drum, the accuracy of this method is low due to temperature unevenness and the inherent lag in temperature-based determination. Therefore, most related technologies use humidity as the basis for determining dryness. Consequently, for condenser washer-dryer combos, there is a lack of technical solutions for accurately determining dryness based on temperature.

[0055] Currently, one related technology provides a solution for temperature-based drying judgment in condenser washer-dryers. This solution involves draining condensate from the condenser into the outer drum during the drying process. Once the condensate level submerges a temperature sensor in the outer drum, the sensor detects the condensate temperature, and the drying judgment is based on this temperature and the inlet air temperature. Because the condensate temperature reflects the air temperature and is minimally affected by uneven temperature distribution of the load, this solution improves the accuracy of temperature-based drying judgment to a certain extent.

[0056] However, in the aforementioned technologies, condensate drains into the outer cylinder and accumulates at the bottom. Only as the water level rises can it submerge the temperature sensor. During this process, the temperature of the condensate inevitably drops. Therefore, there is a significant difference between the temperature detected by the temperature sensor and the actual temperature of the condensate in the condenser. The accuracy of the condensate determination based on the temperature detected by the temperature sensor is still not high and cannot meet the expected requirements for accuracy.

[0057] Based on this, this application provides a garment processing device, which improves the structure of the garment processing device by setting a flow guiding component on the inner wall of the outer cylinder. The flow guiding component directly guides the condensate in the condenser to the temperature sensor, shortening the path and time that the condensate takes from the condenser to the temperature sensor, reducing the temperature loss of the condensate during the process, and making the temperature of the condensate detected by the temperature sensor closer to the temperature of the condensate in the condenser, thereby improving the accuracy of temperature detection and thus improving the accuracy of judgment based on the detected temperature of the condensate.

[0058] Because the temperature of the condensate water accurately reflects the outlet air temperature of the washing drum, and because the condensate water temperature is strongly correlated with the humidity of the load—higher humidity results in more water condensing in the humid air, leading to a higher condensate water temperature; conversely, lower humidity reduces condensation and lower condensate water temperature. Furthermore, since moisture from different parts of the load can evaporate into the air and condense again, mixing with the cooling water in the condenser, the condensate water temperature is minimally affected by uneven load temperature. Therefore, by modifying the equipment structure to automatically and accurately detect the condensate water temperature and then using this temperature-based drying judgment, the accuracy of temperature-based drying judgment in condenser washer-dryers can be improved.

[0059] The garment processing equipment provided in this application embodiment can be a condenser washer-dryer combo. The following detailed description, in conjunction with the accompanying drawings, describes a garment processing equipment, drying control method, and storage medium provided in this application embodiment.

[0060] Some embodiments of this application provide a garment processing device, see [link to relevant documentation] Figure 1 The diagram shows a structural schematic of a garment processing device, which includes: a controller 1, a condenser 2, an outer cylinder 3, a temperature sensor 4 disposed on the inner wall of the outer cylinder 3, and a flow guiding assembly 5;

[0061] A perforation 6 is provided on the side wall of the outer cylinder 3. The condenser 2 is located outside the outer cylinder 3, and the water outlet pipe of the condenser 2 is connected to the perforation 6. The flow guiding component 5 is located below the perforation 6 and is used to guide the condensate flowing out of the perforation 6 to the temperature sensor 4. The controller 1 is communicatively connected to the temperature sensor 4 and is used to make a judgment based on the first temperature of the condensate detected by the temperature sensor 4.

[0062] The communication connection between controller 1 and temperature sensor 4 can be wired or wireless. Since condenser 2 is located at the rear of outer cylinder 3 and is obscured by it, therefore... Figure 1 The condenser 2 is shown in dashed lines. The communication connection between the controller 1 and the temperature sensor 4 is shown in another dashed line.

[0063] Figure 2 The schematic diagram of the garment processing equipment shown illustrates the structure of the condenser 2. Figure 2 The arrows in the diagram indicate the flow path of the condensate. Water with a lower external temperature enters the condenser 2, exchanges heat with the humid and hot air coming out of the clothes processing drum, and forms condensate. The condensate eventually flows into the space between the outer drum 3 and the clothes processing drum.

[0064] Figure 3The schematic diagram of the garment processing equipment shown illustrates the structure of the perforation 6, the temperature sensor 4, and the flow guiding assembly 5. Figure 3 The middle arrow shows the flow path of condensate after it enters the space between the outer drum 3 and the clothes handling drum, that is, it flows from the perforation 6 through the guide assembly 5 to the temperature sensor 4, and finally flows to the drain outlet.

[0065] During the drying process, the hot and humid air exiting the clothes handling drum enters the pipes of condenser 2 and exchanges heat with the cooler water in condenser 2. The water vapor in the hot and humid air condenses into water upon contact with the condenser. In this embodiment, the clothes handling drum can be understood as the inner drum of the clothes handling equipment used to hold the load. In this embodiment, the water formed by the mixture of the water originally in the pipes of condenser 2 and the water precipitated from the hot and humid air is called condensate. Alternatively, the water flowing out of the perforation 6 is called condensate. The water originally in the pipes of condenser 2 can be, for example, water supplied to the pipes of condenser 2 from a cooling water source. The condensate flows from the outlet pipe of condenser 2 to the perforation 6 on the outer drum 3, and then flows from the perforation 6 into the space between the outer drum 3 and the clothes handling drum.

[0066] Because a flow guiding component 5 is installed below the perforation 6, the condensate flowing out of the perforation 6 flows directly to the temperature sensor 4 under the guidance of the flow guiding component 5, thus enabling the temperature sensor 4 to detect the first temperature of the condensate. The temperature sensor 4 transmits the detected first temperature of the condensate to the controller 1, and the controller 1 determines whether the load in the clothes processing drum has been dried based on the first temperature.

[0067] In this embodiment, a perforation 6 is provided on the side wall of the outer cylinder 3, and the water outlet pipe of the condenser 2 is connected to the perforation 6. A flow guiding component 5 is provided on the inner wall of the outer cylinder 3 to directly guide the condensate flowing out of the perforation 6 to the temperature sensor 4. This shortens the path and time required for the condensate to reach the temperature sensor, allowing the temperature sensor 4 to detect the temperature of the condensate more quickly. It also reduces the temperature loss of the condensate before it reaches the temperature sensor 4, making the temperature of the condensate detected by the temperature sensor 4 closer to the temperature of the condensate in the condenser. The temperature detection is more accurate, and the accuracy of the judgment based on the temperature of the condensate is also higher.

[0068] Because the temperature of the condensate detected by the temperature sensor is close to the actual temperature of the condensate in the condenser, and the temperature of the condensate in the condenser can well reflect the outlet temperature of the clothes handling drum, and the temperature of the condensate is strongly correlated with the humidity of the load, and is minimally affected by uneven temperature of the load, the accuracy of temperature-based drying determination in condenser washer-dryers is effectively improved by using the temperature of the condensate detected by the temperature sensor in this embodiment.

[0069] In some embodiments of this application, such as Figure 4 As shown, the flow guiding assembly 5 includes a flow guiding plate 51 and a first flow guiding groove 52; the first flow guiding groove 52 is disposed below the perforation 6, the flow guiding plate 51 is disposed below the first flow guiding groove 52, and the flow guiding plate 51 is disposed above the temperature sensor 4; the first flow guiding groove 52 is used to guide the condensate flowing out of the perforation 6 to the flow guiding plate 51, and the flow guiding plate 51 is used to guide the condensate guided by the first flow guiding groove 52 to the temperature sensor 4.

[0070] First, the condensate flowing from the perforation 6 is guided to the guide plate 51 via the first guide channel 52, and then guided to the temperature sensor 4 via the guide plate 51. The design of the perforation 6, the first guide channel 52, and the guide plate 51 defines the flow path of the condensate. This simple structure allows the condensate to reach the temperature sensor 4 via a very short path after exiting the perforation 6, reducing temperature loss caused by a long flow path. This ensures that the temperature of the condensate detected by the temperature sensor 4 is close to the actual temperature of the condensate in the condenser, improving the accuracy of condensate temperature detection.

[0071] In some embodiments of this application, such as Figure 4 As shown, one side of the guide plate 51 is fixedly connected to the inner wall of the outer cylinder 3. The first end A of the guide plate 51 is higher than the second end B. The first end A is the end of the guide plate 51 that is close to the first guide groove 52, and the second end B is the end of the guide plate 51 that is close to the temperature sensor 4.

[0072] One side of the guide plate 51 is fixedly connected to the inner wall of the outer cylinder 3. The side connected to the inner wall of the outer cylinder 3 can be either side of the guide plate 51. This fixed connection can be achieved by snap-fit ​​structure, adhesive bonding, or the guide plate 51 can be integrally molded with the inner wall of the outer cylinder 3.

[0073] The guide plate 51 is perpendicular to the inner wall of the inner cylinder, or the angle between the inner wall of the inner cylinder above the guide plate 51 and the guide plate 51 can be an acute angle or a small obtuse angle, such as 60°, 90° or 100°.

[0074] When condensate flows down from the first guide channel 52, it first flows to the first end A of the guide plate 51, and then flows through the guide plate 51 to the second end B. The first end A of the guide plate 51 is higher than the second end B, creating a certain height difference in the direction of condensate flow. After being guided onto the guide plate 51, the condensate flows from high to low, making it easy for the guide plate 51 to guide it to the temperature sensor 4. The height difference between the first end A and the second end B of the guide plate 51 accelerates the flow rate of the condensate, allowing it to reach the temperature sensor more quickly. This further shortens the time required for the condensate to reach the temperature sensor 4 from the perforation 6, reduces temperature loss before reaching the temperature sensor 4, and improves the accuracy and reliability of the final detected condensate temperature.

[0075] In some embodiments of this application, such as Figure 4 As shown, the guide plate 51 includes a plate body 511, a first guide rib 512, and a second guide rib 513; one side of the plate body 511 is fixedly connected to the inner wall of the outer cylinder 3, and the first guide rib 512 and the second guide rib 513 protrude from the plate surface of the plate body 511 facing the perforation 6; the first guide rib 512, the second guide rib 513 and the plate surface form a second guide groove 514; the second guide groove 514 is used to guide the condensate water guided by the first guide groove 52 to the temperature sensor 4.

[0076] Since the first guide rib 512 and the second guide rib 513 protrude from the surface of the aforementioned plate, the area between the first guide rib 512, the second guide rib 513, and the plate surface area between them forms an inwardly recessed second guide groove 514. The first guide groove 52 guides the condensate to the guide plate 51, and the condensate flows into the second guide groove 514. The first guide rib 512 and the second guide rib 513 constrain the flow direction of the condensate in the second guide groove 514, preventing the condensate from flowing out from the edge of the guide plate 51. The condensate can flow accurately to the temperature sensor 4 along the second guide groove 514, realizing the direct guidance of condensate from the condenser to the temperature sensor 4 through a simple structure.

[0077] In some embodiments of this application, such as Figure 4 As shown, the distance between the first guide rib 512 and the second guide rib 513 at the first end C of the second guide groove 514 is greater than the distance between the first guide rib 512 and the second guide rib 513 at the second end D of the second guide groove 514; the first end of the second guide groove 514 is the end of the second guide groove 514 close to the perforation 6, and the second end of the second guide groove 514 is the end of the second guide groove 514 close to the temperature sensor 4.

[0078] The first end C of the second guide channel 514 is close to the first guide channel 52, so that the condensate flowing down from the first guide channel 52 can flow exactly to the first end C of the second guide channel 514. The second end D of the second guide channel 514 can be located directly above or diagonally above the temperature sensor 4, so that the condensate flowing out from the second end D of the second guide channel 514 can fall exactly onto the temperature sensor 4 under the action of inertia and gravity.

[0079] The distance between the first guide rib 512 and the second guide rib 513 at the first end C of the second guide channel 514 is the straight-line distance between the endpoints of the first guide rib 512 and the second guide rib 513 at the first end C. Similarly, the distance between the first guide rib 512 and the second guide rib 513 at the second end D of the second guide channel 514 is the straight-line distance between the endpoints of the first guide rib 512 and the second guide rib 513 at the second end D.

[0080] In other words, the flow channel of the second guide channel 514 near the first guide channel 52 is wider than the flow channel near the temperature sensor 4. This provides a larger capacity for the condensate flowing down from the first guide channel 52 at the first end C of the second guide channel 514, reducing the likelihood of condensate overflowing from the guide plate 51 upon reaching it. The flow channel narrows at the second end D of the second guide channel 514, concentrating the condensate and guiding it to the temperature sensor 4. This structural design of the second guide channel 514 allows more condensate to be directed to the temperature sensor 4, improving the accuracy of condensate landing on the sensor and reducing the possibility of condensate not reaching the sensor due to deviations in flow or descent direction.

[0081] In some embodiments of this application, such as Figure 4 As shown, the first guide channel 52 is connected to the end face of the perforation 6; the inner wall surface of the outer cylinder 3 within a preset size range below the perforation 6 is recessed to form the first guide channel 52. The preset size range is used to limit the size of the first guide channel 52. This embodiment does not limit the specific value of the preset size range; in practical applications, it can be set according to requirements, as long as the value of the preset size range allows the first guide channel 52 to successfully guide the condensate flowing from the perforation 6 to the guide plate 51, or ultimately to the temperature sensor 4.

[0082] The first guide channel 52 is formed by the recess in the inner wall of the outer cylinder 3, and the first guide channel 52 is connected to the end face of the perforation 6. In this way, the condensate water comes out from the perforation 6 and flows down along the first guide channel 52 under the action of the wall and gravity, which plays a good role in guiding the flow.

[0083] In some embodiments of this application, such as Figure 4 As shown, the width of the first guide channel 52 near the perforation 6 is greater than the width of the first guide channel 52 near the temperature sensor 4. Alternatively, it can be said that the width of the first guide channel 52 near the perforation 6 is greater than the width of the first guide channel 52 near the guide plate 51.

[0084] The first guide channel 52 is wider at the end near the perforation 6, providing a larger capacity for the condensate flowing out of the perforation 6 and guiding more condensate towards the guide plate 51, or towards the temperature sensor 4. The end of the first guide channel 52 that is closer to the temperature sensor 4 (or the guide plate 51) narrows, concentrating the condensate and allowing it to flow more accurately onto the guide plate 51. This increases the amount of condensate ultimately reaching the temperature sensor 4, thereby improving the accuracy of the temperature sensor 4 in detecting the condensate temperature.

[0085] In some other embodiments of this application, the flow guiding component 5 may only include the flow guiding plate 51 described above; the flow guiding plate 51 is disposed below the perforation 6 and above the temperature sensor 4; the flow guiding plate 51 is used to guide the condensate flowing out of the perforation 6 to the temperature sensor 4.

[0086] The specific structural details of the guide plate 51 are the same as those in the previous embodiment, and will not be repeated here. The difference between this embodiment and the previous embodiment is that in this embodiment, the guide plate 51 is only provided between the perforation 6 and the temperature sensor 4, and the first guide groove 52 is not provided.

[0087] The condensate flowing out of perforation 6 flows directly onto guide plate 51, and then guides the condensate to temperature sensor 4. The design of perforation 6 and guide plate 51 defines the flow path of the condensate, simplifying the structure. This allows the condensate to reach temperature sensor 4 directly after exiting perforation 6 and passing through guide plate 51, reducing temperature loss caused by a long flow path. This ensures that the temperature detected by temperature sensor 4 is closer to the actual temperature of the condensate in the condenser, improving the accuracy of condensate temperature detection.

[0088] In other embodiments of this application, the flow guiding component 5 may also include only the first flow guiding groove 52 described above; the first flow guiding groove 52 is disposed below the perforation 6 and above the temperature sensor 4; the first flow guiding groove 52 is used to guide the condensate flowing out of the perforation 6 to the temperature sensor 4.

[0089] The specific structural details of the first guide channel 52 are the same as those in the previous embodiment, and will not be repeated here. The difference between this embodiment and the previous embodiment is that in this embodiment, the first guide channel 52 is only provided below the perforation 6, and the guide plate 51 is not provided.

[0090] The condensate flowing out of the perforation 6 flows along the first guide channel 52 to the temperature sensor 4. The design of the perforation 6 and the first guide channel 52 defines the flow path of the condensate, resulting in a simple structure. This allows the condensate to reach the temperature sensor 4 directly after exiting the perforation 6 and passing through the first guide channel 52, reducing temperature loss caused by a long flow path. This ensures that the temperature of the condensate detected by the temperature sensor 4 is close to the actual temperature of the condensate in the condenser, improving the accuracy of condensate temperature detection.

[0091] In some embodiments of this application, such as Figure 4 As shown, the flow guiding component 5, the perforation 6, and the temperature sensor 4 are all located on the same inner wall of the outer cylinder 3. This arrangement shortens the flow path of the condensate from the perforation 6 to the temperature sensor 4. In a single drying cycle, when the condensate first flows out of the perforation 6, the time it takes for the condensate to reach the temperature sensor 4 is very short, allowing for faster temperature detection. Furthermore, the shorter flow path reduces temperature loss before reaching the temperature sensor 4, resulting in a more accurate temperature reading that is closer to the temperature of the humid air exiting the clothes drying drum.

[0092] In some embodiments of this application, a heating tube is provided at the bottom of the outer drum 3, and a temperature sensor 4 is located at the heating tube. The heating tube at the bottom of the outer drum 3 is used to heat the water between the outer drum 3 and the clothes processing drum. Typically, a temperature sensor 4 is located at this heating tube to detect the water temperature during the heating process. In this embodiment, the temperature sensor 4 at the heating tube can be reused in the drying process to detect the temperature of the condensate flowing out of the condenser 2. This eliminates the need for an additional temperature sensor 4, reducing costs and improving the utilization rate of the temperature sensor 4 at the heating tube.

[0093] Of course, in some other embodiments, a temperature sensor 4 can also be additionally provided on the inner wall of the outer cylinder 3 to detect the temperature of the condensate flowing out of the condenser 2.

[0094] In this embodiment, a perforation is provided on the side wall of the outer cylinder, and the water outlet pipe of the condenser is connected to the perforation. A flow guiding component is provided on the inner wall of the outer cylinder to directly guide the condensate flowing out of the perforation to the temperature sensor. This shortens the path and time that the condensate takes from the condenser to the temperature sensor, reduces the temperature loss of the condensate during the process, and makes the temperature of the condensate detected by the temperature sensor closer to the temperature of the condensate in the condenser. This improves the accuracy of temperature detection and, consequently, the accuracy of the judgment based on the detected temperature of the condensate.

[0095] Some embodiments of this application provide a drying control method, which is applied to the garment processing equipment provided in the above embodiments, wherein the garment processing equipment may be a condenser washer-dryer combo. See also Figure 5 The method may specifically include the following steps 101 and 102.

[0096] Step 101: Obtain the first temperature of the condensate flowing out of the condenser detected by the temperature sensor during the drying process, and obtain the second temperature, which includes the air inlet temperature or the temperature inside the clothes processing drum.

[0097] Step 102: Based on the first temperature and the second temperature, determine the dryness of the load in the garment processing drum.

[0098] The execution subject of this application embodiment is a clothing processing device. The structural details of the clothing processing device can be referred to the structural description of the clothing processing device in the foregoing embodiments, and will not be repeated in this embodiment.

[0099] During the drying process, after the humid, hot air in the clothes handling drum exchanges heat with the condenser through the pipes, the condensate in the condenser flows out through perforations in the side wall of the outer drum and along the guide assembly to the temperature sensor. The temperature sensor detects the initial temperature of the condensate and transmits this initial temperature to the controller.

[0100] A temperature sensor can also be installed in the air inlet channel of the garment processing equipment to detect the inlet air temperature of the garment processing drum. A temperature sensor can also be installed in the garment processing drum of the garment processing equipment to detect the temperature inside the drum. In this embodiment, the detected inlet air temperature or the temperature inside the drum is referred to as the second temperature.

[0101] The controller determines the dryness of the load based on a first temperature and a second temperature. The first temperature is the temperature of the condensate flowing from the condenser, detected by a temperature sensor. Since the condenser is connected to the perforations on the outer drum sidewall, the condensate flows directly to the temperature sensor after exiting the perforations, guided by the flow guide assembly. This shortens the path and time of the condensate from the condenser to the temperature sensor, effectively reducing temperature loss and making the condensate temperature detected by the sensor closer to the temperature of the condensate in the condenser. The temperature of the condensate in the condenser effectively reflects the outlet temperature of the clothes handling drum, and the condensate temperature is strongly correlated with the humidity of the load, with minimal impact from uneven load temperature. Therefore, determining dryness based on the condensate temperature detected by the temperature sensor in this embodiment improves the accuracy of temperature-based dryness determination in washer-dryer combos.

[0102] In some embodiments of this application, the process of determining dryness may specifically include first determining the absolute value of the temperature difference between a first temperature and a second temperature; and then determining the dryness of the load in the garment processing drum based on the absolute value of the temperature difference.

[0103] The first temperature is the temperature of the condensate flowing out of the condenser, which accurately reflects the outlet air temperature of the garment processing drum. The second temperature is the inlet air temperature or the temperature inside the drum. Therefore, the absolute value of the temperature difference between the first and second temperatures reflects the temperature change of the hot air after heat exchange with the load in the garment processing drum. This temperature change is strongly correlated with the dryness of the load; the larger the temperature change, the less dry the load, and vice versa. Based on this absolute temperature difference, it is possible to accurately determine whether the load has been dried.

[0104] In this embodiment, a perforation is provided on the side wall of the outer cylinder, connecting the condenser's outlet pipe to the perforation. A flow guiding component is provided on the inner wall of the outer cylinder to directly guide the condensate flowing from the perforation to the temperature sensor. This shortens the path and time the condensate takes from the condenser to the temperature sensor, reducing temperature loss during this process. Consequently, the temperature of the condensate detected by the temperature sensor is closer to the temperature of the condensate in the condenser, improving the accuracy of temperature detection. Because the temperature of the condensate detected by the temperature sensor is close to the temperature of the condensate in the condenser, it effectively reflects the outlet temperature of the garment processing drum and has a strong correlation with the humidity of the load. Furthermore, the detected temperature is minimally affected by uneven temperature distribution of the load. Therefore, using the condensate temperature detected by the temperature sensor in this embodiment improves the accuracy of temperature-based filtration.
