Description

Technical Field

[0001] This invention relates to the field of clothing processing technology, and in particular to a control method for clothing processing equipment and clothing processing equipment. Background Technology

[0002] Clothing processing equipment such as dryers, washing machines with drying functions, and garment care machines can all dry and heat clothes. Taking a heat pump type clothing processing equipment as an example, it includes a drying duct and a clothing processing chamber. The air outlet of the drying duct is connected to the air inlet of the clothing processing chamber, and the air outlet of the clothing processing chamber is connected to the air inlet of the drying duct. The drying duct is equipped with a drying fan, compressor, evaporator, condenser, and throttling device. The compressor, evaporator, condenser, and throttling device are connected to form a refrigerant circulation loop to heat the airflow within the drying duct. When the drying fan is running, it delivers the heated airflow to the clothing processing chamber, carrying away the moisture from the clothes and returning it to the drying duct, thus achieving the drying of the clothes through this cycle.

[0003] In existing heat pump-type garment processing equipment, the humid air in low-temperature environments heats up slowly if relying solely on the heat pump system. A condensation system, consisting of an evaporator and a condenser, condenses most of the moisture in the airflow flowing out of the garment processing chamber from a gaseous state into a liquid, thereby reducing the moisture content of the airflow after passing through the condenser. When the temperature difference between the condenser and evaporator in the drying duct is small, the condensation effect is poor, resulting in low drying efficiency. The garment processing equipment cannot consistently dry clothes efficiently, leading to prolonged drying times or clothes remaining dry after the preset drying time, resulting in a poor user experience.

[0004] Therefore, there is an urgent need for a control method and a garment processing device to solve the aforementioned problems in the existing technology. Summary of the Invention

[0036] As an optional embodiment of the garment processing equipment control method provided by the present invention, the garment processing equipment control method further includes:

[0049] The clothing processing equipment control method and equipment provided by this invention acquire the temperature difference between the evaporator and condenser and / or the humidity value inside the clothing processing chamber in real time after the clothing processing program is started. The temperature difference between the evaporator and condenser affects the drying efficiency of the clothing processing equipment. When the temperature difference is small, the condensation effect on the moisture in the airflow flowing through them is poor, resulting in low drying efficiency. When the humidity value inside the clothing processing chamber is low, the condensation efficiency of the evaporator and condenser is also low. Therefore, based on the acquired temperature difference between the evaporator and condenser and / or the humidity value inside the clothing processing chamber, it is determined whether to activate the auxiliary heating function of the drying duct. This accelerates the temperature rise rate inside the drying duct when the airflow temperature rises slowly, increasing the temperature of the airflow entering the clothing processing chamber. In other words, when the drying efficiency of the heat pump system is low, the auxiliary heating function is activated in a timely manner to improve the overall drying efficiency of the clothing processing equipment. Throughout the drying process, this ensures that the clothing processing equipment dries clothes efficiently, guaranteeing that the clothes are dried to the user's desired level and improving the user experience.

[0068] In the embodiments of the present invention, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0069] Example 1

[0070] This embodiment provides a control method for a clothing processing device, ensuring that the device dries clothes efficiently throughout the drying process, guaranteeing that the clothes are dried to the user's desired level and improving the user experience. The clothing processing device can be a dryer, a washing machine with a drying function, a garment care machine, etc. The device includes a connected clothing processing chamber 20 and a drying duct 3. The drying duct 3 contains an evaporator 41 and a condenser 42 (see...). Figure 5 ).

[0071] like Figure 1 As shown, the garment processing equipment control method provided in this embodiment includes:

[0072] S1. Obtain the temperature difference between the evaporator 41 and the condenser 42 and / or obtain the humidity value inside the clothing processing chamber 20;

[0073] S2. Determine whether to activate the auxiliary heating function for the drying duct 3 based on the temperature difference and / or humidity value.

[0074] It should be noted that steps S1 and S2 are continuously executed in a loop throughout the entire drying process until the drying program ends.

[0075] The clothing processing equipment control method provided in this embodiment acquires the temperature difference between the evaporator 41 and the condenser 42 and / or the humidity value inside the clothing processing chamber 20 in real time after the clothing processing program is started. The temperature difference between the evaporator 41 and the condenser 42 affects the drying efficiency of the clothing processing equipment. When the temperature difference is small, the condensation effect on the moisture in the airflow passing through them is poor, resulting in low drying efficiency. When the humidity value inside the clothing processing chamber 20 is low, the condensation efficiency of the evaporator 41 and the condenser 42 is low. Therefore, based on the temperature difference between the evaporator 41 and the condenser 42 and / or the humidity value inside the clothing processing chamber 20, it is determined whether to activate the auxiliary heating function of the drying duct 3. This accelerates the temperature rise rate inside the drying duct 3 when the airflow temperature rises slowly, thereby increasing the temperature of the airflow entering the clothing processing chamber 20. In other words, when the drying efficiency of the heat pump system 4 is low, the auxiliary heating function is activated in a timely manner to improve the overall drying efficiency of the clothing processing equipment. Throughout the drying process, this ensures that the clothing processing equipment dries clothes at a high efficiency, guaranteeing that the clothes are dried to the degree required by the user and improving the user experience.

[0076] Specifically, such as Figure 2 As shown, in this embodiment, step S2, "determining whether to activate the auxiliary heating function for the drying duct 3 based on the temperature difference and / or humidity value," includes:

[0077] When the temperature difference ΔT between the evaporator 41 and the condenser 42 is less than or equal to the first temperature difference threshold T3, the auxiliary heating function is activated.

[0078] When the temperature difference ΔT between the evaporator 41 and the condenser 42 is less than or equal to the first temperature difference threshold T3, the condensation effect of the condensation system composed of the evaporator 41 and the condenser 42 is poor, resulting in a slow temperature rise of the airflow in the drying duct 3. At this time, the auxiliary heating function is activated to heat the airflow in the drying duct 3, thereby accelerating the temperature rise of the airflow in the drying duct 3 and increasing the temperature of the airflow entering the clothing processing chamber 20, thus ensuring the high drying efficiency of the clothing processing equipment at this time.

[0079] More specifically, such as Figure 2 As shown, in step S2, "determining whether to provide auxiliary heating to the drying duct 3 based on the temperature difference and / or humidity value" further includes:

[0080] When the temperature difference ΔT between the evaporator 41 and the condenser 42 is greater than or equal to the second temperature difference threshold T4, and / or when the real-time humidity value H1 in the clothing processing chamber 20 is greater than or equal to the humidity threshold H0, the auxiliary heating function is controlled to be turned off or the auxiliary heating function is kept off; wherein, the second temperature difference threshold T4 is greater than the first temperature difference threshold T3.

[0081] When the temperature difference ΔT between evaporator 41 and condenser 42 is greater than or equal to the second temperature difference threshold T4, it indicates that the temperature difference between the two units has risen to a suitable level, the condensation effect of the condensation system composed of evaporator 41 and condenser 42 is good, the airflow in the drying duct 3 heats up quickly, and the heat pump system 4 (see...) Figure 5 The drying efficiency is relatively high, and at this time the auxiliary heating function can be turned off to avoid wasting energy.

[0082] When the real-time humidity value H1 in the clothing processing chamber 20 is greater than or equal to the humidity threshold H0, the condensation effect of the condensation system consisting of evaporator 41 and condenser 42 is better, and the drying efficiency of heat pump system 4 is higher. At this time, the auxiliary heating function can be turned off.

[0083] It is understandable that when either of the following conditions is met, namely, "the temperature difference ΔT between the evaporator 41 and the condenser 42 is greater than or equal to the second temperature difference threshold T4" or "the real-time humidity value H1 in the clothing processing chamber 20 is greater than or equal to the humidity threshold H0", the auxiliary heating function can be turned off. When both conditions are met, the auxiliary heating function can also be turned off.

[0084] Further, see Figure 2 When the temperature difference ΔT between the evaporator 41 and the condenser 42 is greater than the first temperature difference threshold T3 and less than the second temperature difference threshold T4, and the humidity value H1 in the clothing processing chamber 20 is less than the humidity threshold H0, it indicates that the condensation effect of the condensing system is poor and the drying efficiency of the heat pump system 4 is low. At this time, the auxiliary heating function is kept running until at least one of the above two conditions is met, at which point the auxiliary heating function is turned off.

[0085] For example, the first temperature difference threshold T3 ranges from 10℃ to 20℃. For instance, the first temperature difference threshold T3 can be 10℃, 11℃, 12℃, 13℃, 14℃, 15℃, 16℃, 17℃, 18℃, 19℃, 20℃, etc., but is not limited to the values ​​listed above. In this embodiment, the first temperature difference threshold T3 is 15℃.

[0086] For example, the second temperature difference threshold T4 ranges from 15℃ to 25℃. For instance, the second temperature difference threshold T4 can be 15℃, 16℃, 17℃, 18℃, 19℃, 20℃, 21℃, 22℃, 23℃, 24℃, 25℃, etc., but is not limited to the values ​​listed above. In this embodiment, the second temperature difference threshold T4 is 20℃.

[0087] For example, the temperature difference ΔT between the evaporator 41 and the condenser 42 is in the range of 5°C to 35°C, such as 10°C, 14°C, 18°C, 25°C, etc. This is related to the specific model and processing program of the garment processing equipment, and it changes constantly during the drying process, and is not limited to this value range.

[0088] For example, the humidity threshold H0 ranges from 80% to 95%, such as 80%, 82%, 85%, 87%, 89%, 90%, 92%, 95%, etc., but is not limited to the values ​​listed above. In this embodiment, the humidity threshold H0 is 90%.

[0089] The drying process of the garment processing equipment provided in this embodiment is described below with reference to a specific implementation scheme. The first temperature difference threshold T3 is 15℃, the second temperature difference threshold T4 is 20℃, and the humidity threshold H0 is 90%.

[0090] After the processing program starts, the real-time temperature of evaporator 41 T1 = 50℃ and the temperature of condenser 42 T2 = 60℃ are obtained. Then the temperature difference between evaporator 41 and condenser 42 ΔT = T2 - T1 = 10℃ ≤ T3 = 15℃. At this time, the condensation efficiency is low, so the auxiliary heating function is turned on.

[0091] After the auxiliary heating function is turned on, when the temperature of evaporator 41 is T1 = 55℃ and the temperature of condenser 42 is T2 = 80℃, then condition 1: the temperature difference between evaporator 41 and condenser 42 ΔT = T2 - T1 = 25℃ > T4 = 20℃, and condition 2: the humidity value in the clothing processing chamber 20 is H1 = 80% < humidity threshold H0 = 90%. If either condition 1 or condition 2 is met, the condensation efficiency is high, and then the auxiliary heating function is turned off.

[0092] When the evaporator 41 temperature T1 = 68℃ and the condenser 42 temperature T2 = 82℃ is obtained, the temperature difference between the evaporator 41 and the condenser 42 is ΔT = T2 - T1 = 14℃ ≤ T3 = 15℃. Therefore, the condensation efficiency is low, and the auxiliary heating function is turned on again.

[0093] When the evaporator 41 temperature T1 = 72℃ and the condenser 42 temperature T2 = 90℃ is obtained, then condition 1: the temperature difference between evaporator 41 and condenser 42 ΔT = T2 - T1 = 18℃ < T4 = 20℃, and condition 2: the humidity value in the clothing processing chamber 20 H1 = 92% > humidity threshold H0 = 90%. If either condition 1 or condition 2 is satisfied, the condensation efficiency is high, and the auxiliary heating function is turned off.

[0094] During the drying process, T1, T2, and H1 are acquired in real time. If the temperature difference ΔT ≤ T3, the auxiliary heating function is activated. If the temperature difference ΔT ≥ T4 and / or the humidity value H1 in the clothing processing chamber 20 ≥ the humidity threshold H0, the auxiliary heating function is deactivated until the drying process is complete.

[0095] Example 2

[0096] like Figure 3 As shown, this embodiment provides a control method for a garment processing device, which is a further improvement on the first embodiment.

[0097] The phrase "when the temperature difference ΔT between evaporator 41 and condenser 42 is less than or equal to the first temperature difference threshold T3, the auxiliary heating function is activated" includes:

[0098] Calculate the duration t1 for which the temperature difference ΔT between the evaporator 41 and the condenser 42 is less than or equal to the first temperature difference threshold T3, and determine whether the duration t1 has reached the first preset duration. If the duration t1 has reached the first preset duration, control the auxiliary heating function to start. If the duration t1 has not reached the first preset duration, control the auxiliary heating function to remain off.

[0099] For example, the first preset duration ranges from 2s to 30s. For instance, the first preset duration can be 5s, 10s, 12s, 15s, 20s, 25s, 28s, 30s, etc., but is not limited to these. In other words, in this embodiment, when the time for which the temperature difference ΔT is less than or equal to the first temperature difference threshold T3 reaches the first preset duration, it can be determined that the condensation effect of the airflow within the drying duct 3 is poor at this time. Only then is the auxiliary heating function activated to avoid frequent start-stop of the auxiliary heating function.

[0100] Similarly, "when the temperature difference ΔT between the evaporator 41 and the condenser 42 is greater than or equal to the second temperature difference threshold T4, and / or when the real-time humidity value H1 in the clothing processing chamber 20 is greater than or equal to the humidity threshold H0, controlling the auxiliary heating function to turn off or maintaining the auxiliary heating function in a turned-off state" includes:

[0101] Calculate the duration t2 during which the temperature difference ΔT between the evaporator 41 and the condenser 42 is greater than or equal to the second temperature difference threshold T4, and determine whether the duration t2 has reached the second preset duration. If the duration t2 has reached the second preset duration, control the auxiliary heating function to turn off; and / or, calculate the duration t3 during which the real-time humidity value H1 in the clothing processing chamber 20 is greater than or equal to the humidity threshold H0, and determine whether the duration t3 has reached the third preset duration. If the duration t3 has reached the third preset duration, control the auxiliary heating function to turn off.

[0102] When the temperature difference ΔT is greater than or equal to the second temperature difference threshold T4 and the duration t2 reaches the second preset duration, it can be determined that the condensation effect of the airflow in the drying duct 3 is better and the drying efficiency of the heat pump system 4 is higher. At this time, the auxiliary heating function can be turned off to avoid the auxiliary heating function from frequently starting and stopping and causing failure.

[0103] For example, the value of the second preset duration is in the range of 2s to 30s. For instance, the value of the second preset duration is 5s, 10s, 12s, 15s, 20s, 25s, 28s, 30s, etc., but not limited to these.

[0104] When the real-time humidity value H1 in the clothing processing chamber 20 is greater than or equal to the humidity threshold H0 and the duration t3 reaches the third preset duration, it can be determined that the condensation effect of the airflow in the drying duct 3 is better and the drying efficiency of the heat pump system 4 is higher. At this time, the auxiliary heating function can be turned off to avoid the auxiliary heating function from being frequently turned on, which would reduce its service life.

[0105] For example, the value of the third preset duration is in the range of 2s to 30s. For instance, the value of the third preset duration is 5s, 10s, 12s, 15s, 20s, 25s, 28s, 30s, etc., but not limited to these.

[0106] Example 3

[0107] This embodiment provides a control method for a garment processing device, which is further defined based on Embodiment 1 and Embodiment 2.

[0108] In this embodiment, combined with Figure 5 At least one heating device 5 is installed inside the drying duct 3, located downstream of the condenser 42. When the drying efficiency of the heat pump system 4 decreases, the heating device 5 can be turned on to increase the temperature rise rate of the airflow inside the drying duct 3, thereby improving the overall drying efficiency of the garment processing equipment. Furthermore, the heating device 5 is positioned close to the air inlet 22 of the garment processing chamber 20 to reduce heat loss and improve the drying effect.

[0109] In some implementations, the step of "activating auxiliary heating function for drying duct 3" includes controlling the heating device 5 to turn on or off. In this case, only one heating device 5 may be installed. The heating device 5 is activated when the temperature difference ΔT is less than or equal to a first temperature difference threshold T3 to assist in heating the airflow within the drying duct 3. When condition 1 is met: the temperature difference ΔT between the evaporator 41 and the condenser 42 ≥ T4, and / or condition 2 is met: the humidity value H1 within the clothing processing chamber 20 ≥ the humidity threshold H0, the heating device 5 is turned off to save energy.

[0110] In some implementation schemes, the step of "activating the auxiliary heating function of the drying duct 3" includes: adjusting the power of the heating device 5 from a first power to a second power. In this case, only one heating device 5 can be installed, and the heating device 5 is always on, but it has both a state of operating at the first power and a state of operating at the second power, where the second power is greater than the first power. The state of operating at the first power corresponds to the state of the auxiliary heating function being off, and the state of operating at the second power corresponds to the state of the auxiliary heating function being on. When the power of the heating device 5 is increased to the second power, auxiliary heating of the drying duct 3 can still be achieved.

[0111] For example, the first power value ranges from 500W to 800W, such as 500W, 600W, 650W, 700W, 800W, etc., but is not limited to the listed values. The second power value ranges from 800W to 2000W, such as 800W, 900W, 950W, 1000W, 1500W, 1800W, 2000W, etc., but is not limited to the listed values.

[0112] In some implementations, the step of "activating auxiliary heating function for drying duct 3" includes: increasing the number of heating devices 5 that are turned on. At least two heating devices 5 are set up at this time. For example, some of the heating devices 5 are kept on throughout the drying process. When it is determined that the temperature difference ΔT between the evaporator 41 and the condenser 42 is less than or equal to the first temperature difference threshold T3, the remaining heating devices 5 are turned on to provide auxiliary heating to the drying duct 3.

[0113] Example 4

[0114] like Figure 4 As shown, this embodiment provides a control method for a garment processing device, which is further defined based on Embodiment 1, Embodiment 2 and Embodiment 3.

[0115] In this embodiment, the step of "obtaining the temperature difference between the evaporator 41 and the condenser 42" includes:

[0116] The temperature at multiple first measuring points of the evaporator 41 is obtained, and the average value of the temperatures at multiple first measuring points is determined as the real-time temperature T1 of the evaporator 41.

[0117] The temperature at multiple second measuring points of the condenser 42 is obtained, and the average value of the temperatures at multiple second measuring points is determined as the real-time temperature T2 of the condenser 42.

[0118] The difference between real-time temperature T1 and real-time temperature T2 is defined as the temperature difference ΔT between evaporator 41 and condenser 42.

[0119] In other words, multiple measuring points are set on the evaporator 41, defined as the first measuring point. Multiple measuring points are set on the condenser 42, defined as the second measuring point. By simultaneously detecting the temperature values ​​of multiple first measuring points and taking the average, and simultaneously detecting the temperature values ​​of multiple second measuring points and taking the average, the accurate real-time temperature T1 of the evaporator 41 and the real-time temperature T2 of the condenser 42 can be obtained. This ensures the accurate calculation of the temperature difference ΔT between the evaporator 41 and the condenser 42, and improves the reliability of the control method.

[0120] In this embodiment, "obtaining the humidity value inside the clothing processing chamber 20" includes:

[0121] The humidity values ​​of multiple moisture measuring points inside the garment processing chamber 20 are obtained, and the average value of the humidity values ​​of multiple moisture measuring points is determined as the real-time humidity value H1 inside the garment processing chamber 20.

[0122] In other words, multiple humidity measuring points are set in the foreign matter handling chamber of the clothing handling equipment. By simultaneously detecting the humidity values ​​of these multiple humidity measuring points and taking the average value, an accurate real-time humidity value H1 in the clothing handling chamber 20 can be obtained. This makes the determination of whether the real-time humidity value H1 in the clothing handling chamber 20 is greater than or equal to the humidity threshold H0 more accurate, which helps to ensure that the clothing handling equipment always operates with high drying efficiency.

[0123] Example 5

[0124] This embodiment provides a control method for a garment processing device, which is further defined based on Embodiment 1, Embodiment 2, Embodiment 3 and Embodiment 4.

[0125] In this embodiment, the clothing processing equipment control method further includes:

[0126] When the single-use duration of the auxiliary heating function reaches the fourth preset duration, the evaporator 41 is cooled down, and the heat on the evaporator 41 is transferred to the outside of the clothing processing equipment or to the clothing processing chamber 20 of the clothing processing equipment.

[0127] When the temperature difference ΔT between the evaporator 41 and the condenser 42 is less than or equal to the first temperature difference threshold T3, the heating device 5 is turned on and a timer is started. When the heating device 5 has been on for a fourth preset duration, it indicates that at least one of conditions 1 and 2 is still not met. At this time, the evaporator 41 can be cooled down to increase the temperature difference ΔT between the evaporator 41 and the condenser 42, thereby satisfying condition 1, avoiding the heating device 5 from being on for a long time, and reducing energy consumption.

[0128] For example, a cooling fan and a heat pipe can be installed at the location of the evaporator 41. An electrically controlled valve is installed inside the heat pipe, and the cooling fan is located at the air inlet 22 of the heat pipe. By opening the electrically controlled valve and the cooling fan, the heat at the location of the evaporator 41 can be conducted away. Furthermore, the end of the heat pipe away from the evaporator 41 can be connected to the outside to directly exhaust the heat of the evaporator 41 to the outside of the clothing processing equipment, or it can be connected to the air inlet 22 of the clothing processing chamber 20 to conduct the heat of the evaporator 41 into the clothing processing chamber 20 to participate in the drying of the clothes.

[0129] For example, the value of the fourth preset duration is in the range of 1 min to 5 min. For example, the value of the fourth preset duration is 1 min, 1.5 min, 2 min, 2.5 min, 3 min, 3.5 min, 4 min, 5 min, etc., but is not limited to the listed values.

[0130] Example 6

[0131] This embodiment provides a garment processing device for implementing the garment processing device control method described in any of the above embodiments. Figure 5 and Figure 6 As shown, the garment processing equipment includes a housing 1, a garment processing drum 2, a drying air duct 3, a heat pump system 4, a heating device 5, a temperature difference acquisition module 7, a humidity detection module 8, and a control module 9.

[0132] The system includes a clothing processing drum 2 housed within the housing 1, defining a clothing processing chamber 20. The clothing processing drum 2 has an air outlet 21 and an air inlet 22. A drying duct 3 is located within the housing 1, with its air inlet 31 connected to the air outlet 21 and its air outlet 32 ​​connected to the air inlet 22. A heat pump system 4 includes a compressor 43, an evaporator 41, a condenser 42, and a throttling device, all housed within the drying duct 3. The condenser 42 is located downstream of the evaporator 41. The compressor 43, evaporator 41, condenser 42, and throttling device are connected to form a circulating loop for the heat exchange medium. A heating device 5 is located within the drying duct 3. A temperature difference acquisition module 7 is located within the drying duct 3 to acquire the temperature difference between the evaporator 41 and the condenser 42. A humidity detection module 8 is located within the clothing processing chamber 20 to detect the humidity value H1 within the clothing processing chamber 20. A control module 9 is communicatively connected to the temperature difference acquisition module 7 and / or the humidity detection module 8.

[0133] When the temperature difference ΔT between the evaporator 41 and the condenser 42 obtained by the temperature difference acquisition module 7 is less than or equal to the first temperature difference threshold T3, the control module 9 controls the heating device 5 to turn on to provide auxiliary heating for the drying duct 3. When the temperature difference acquisition module 7 obtains a temperature difference ΔT greater than or equal to the second temperature difference threshold T4 and / or the humidity detection module 8 obtains a humidity value H1 greater than or equal to the humidity threshold H0, the control module 9 controls the heating device 5 to turn off.

[0134] See Figure 6 The temperature difference acquisition module 7 includes a first temperature detection unit 71, a second temperature detection unit 72, and an acquisition unit 73. The first temperature detection unit 71 is located on the evaporator 41 and is used to detect the real-time temperature T1 of the evaporator 41. The second temperature detection unit 72 is located on the condenser 42 and is used to detect the real-time temperature T2 of the condenser 42. The acquisition unit 73 is used to acquire the difference between the real-time temperature T1 and the real-time temperature T2, and transmit the difference information to the control module 9. The control module 9 controls the heating device 5 to turn on or off according to the information.

[0135] For example, both the first temperature detection unit 71 and the second temperature detection unit 72 include temperature sensors. The humidity detection module 8 includes a humidity sensor. The acquisition unit 73 can be integrated with the control module 9, for example, integrated into the computer board of the garment processing equipment.

[0136] Furthermore, a drying fan 6 is also installed inside the drying duct 3. The drying fan 6 provides power for the airflow circulation, causing the airflow to circulate between the clothes handling drum 2 and the drying duct 3. The heating device 5 is located downstream of the condenser 42 and downstream of the drying fan 6 to reduce heat loss and maintain a higher temperature for the airflow flowing into the clothes handling drum 2. It can be positioned near the air inlet 22 of the clothes handling drum 2.

[0137] For example, the heating device 5 is a heating resistance wire, which can generate heat when energized.
