Background Art

[0002] The clothing processing equipment uses a fan to drive the circulating airflow. The airflow passes through the heating drying tunnel, the temperature rises, and the high-temperature airflow enters the inner drum, thereby evaporating the moisture in the clothes. Then it enters the condenser, and some of the moisture in the airflow is removed by water condensation or air condensation. Then, under the action of the fan, the airflow enters the hot air drying tunnel again, and this cycle is repeated to dry the clothes.

[0003] The drying control method of existing clothing processing equipment sets preset temperature control conditions corresponding to each drying stage. The temperature sensor detects the heating temperature at the heating tube and the corresponding air inlet temperature of the fan in real time. According to the preset temperature control conditions, heating temperature and air inlet temperature corresponding to each drying stage, the load is dried quickly and efficiently by changing the heating power of the heating tube. However, the drying control method of existing clothing processing equipment can only increase or decrease the heating power of the heating tube. The heating power adjustment gear is limited and the adjustable range is not large. In addition, the fan of the existing clothing processing equipment maintains a fixed operating speed until the drying is completed.

BRIEF DESCRIPTION OF THE DRAWINGS

[0021] Figure 1 is a cross-sectional view of an embodiment of a clothes processing device of the present invention.

[0022] Figure 2 4 is a flow chart of an embodiment of a drying control method for a clothes processing device of the present invention.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments. DETAILED DESCRIPTION

[0024] Example of a drying control method for a clothes processing device:

[0025] See also Figure 1 The clothing processing apparatus of this embodiment includes an inner drum 11 and a circulation duct 12 disposed outside the inner drum 11. The air inlet 121 and the return air outlet 122 of the circulation duct 12 are respectively connected to the inner drum 11. A blower device 14 and a heating device 13 are disposed within the circulation duct 12. A first temperature sensor 15 is disposed on the side of the heating device 13 near the air inlet 121. The first temperature sensor 15 is used to detect the inlet air temperature T1 of the heating device 13 in real time. A second temperature sensor 16 is disposed on the side of the blower device 14 near the return air outlet 122. The second temperature sensor 16 is used to detect the return air temperature T2 of the blower device 14 in real time. The heating device 13 of the clothing processing apparatus of this embodiment heats the air within the circulation duct 12. The heated air flows into the inner drum 11 of the clothing processing apparatus, dries the clothes within the clothing processing drum, and is then circulated under the drive of the blower device 14.

[0026] When a user wishes to dry a load using the laundry treatment device of this embodiment, the load, which can be damp clothing, is placed into the inner drum 11 of the laundry treatment device. The load is first weighed, followed by a pre-drying spin cycle. After spin cycle, the load is weighed again, and then the drying cycle begins. The drying process of this embodiment sequentially comprises a rapid heating phase, an evaporation phase, a volatilization phase, and a rapid cooling phase. During the rapid heating phase, the temperature within the inner drum 11 continues to rise rapidly. During the evaporation phase, moisture is present on the surface of the load and continuously evaporates from the surface, causing the mass of the damp load to decrease at a constant rate. During the volatilization phase, moisture is removed from the surface of the load, and moisture moves from the interior to the surface. This volatilization requires a lower drying temperature to improve drying efficiency. During the rapid cooling phase, the temperature of the load and inner drum 11 is rapidly reduced, so that when the user removes the load from the inner drum 11, the temperature does not exceed 50°C, causing sensory discomfort or burns.

[0027] See also Figure 2 , Figure 2 4 is a flow chart of the drying control method of the clothes processing device of this embodiment. The specific steps of the drying control method of the clothes processing device of this embodiment are as follows.

[0028] First, execute step S1 to start the drying operation, that is, control the clothing processing equipment to enter the drying program. At this time, the blowing device 14 and the heating device 13 are turned on, the blowing device 14 runs at a preset wind wheel speed, and the heating device 13 runs at a preset heating power, and the inlet air temperature T1 of the heating device 13 is obtained through the first temperature sensor 15, and the return air temperature T2 of the blowing device 14 is obtained through the second temperature sensor 16.

[0029] Then, step S2 is executed to control the clothes processing device to enter the rapid heating stage, that is, the current drying stage of the clothes processing device is the rapid heating stage.

[0030] Then, step S3 is executed to determine whether the inlet air temperature T1 is greater than the return air temperature T2. If so, step S4 is executed; if not, step S19 is executed to end the drying operation.

[0031] If the inlet air temperature T1 is greater than the return air temperature T2, indicating that the temperature of the inner drum 11 is low, step S4 is executed to adjust the heating power of the heating device 13 to a first power P1 and the rotor speed of the blower device 14 to a first speed V1. The first power P1 is the maximum heating power of the heating device 13, and the first speed V1 is the minimum rotor speed of the blower device 14.

[0032] Specifically, the heating device 13 is controlled to operate at the maximum heating power so that the temperature of the air flow entering the inner drum 11 is higher. At the same time, the blowing device 14 is operated at the minimum wind wheel speed so that the high-temperature air flow is maintained in the inner drum 11 for a long time, so that the temperature of the inner drum 11 can be heated quickly and efficiently, greatly shortening the drying time and thus improving the drying efficiency.

[0033] When it is determined that the inlet air temperature T1 is less than or equal to the return air temperature T2, it indicates that the temperature of the inner drum 11 is at a high temperature. If further heating is performed, overheating will occur, causing damage to the clothes. In this case, step S19 is executed to directly end the drying operation.

[0034] After the heating device 13 operates at the first power P1 and the blowing device 14 operates at the first speed V1, step S5 is executed to determine whether |T2-T3|≤ΔT1. If so, step S6 is executed to control the clothing processing apparatus to enter the evaporation stage. If not, step S4 is executed to continuously operate the heating device 13 at the first power P1 and the blowing device 14 at the first speed V1. T3 is the preset temperature control condition for the inner drum 11 during the rapid heating stage, i.e., T3 is the preset temperature of the inner drum 11 during the rapid heating stage, and ΔT1 is the first preset temperature difference.

[0035] Specifically, while the heating device 13 is operating at a first power P1 and the blower 14 is operating at a first speed V1, the return air temperature T2 gradually increases, that is, starting from room temperature. Therefore, the return air temperature T2 gradually increases from less than the preset temperature T3 of the inner drum 11 toward the preset temperature T3 of the inner drum 11. For example, if the preset temperature T3 of the inner drum 11 is 60°C, while the heating device 13 is operating at the first power P1 and the blower 14 is operating at the first speed V1, the return air temperature T2 gradually increases from 30°C, room temperature. If the judgment condition of |T2-T3|≤ΔT1 is not met, the heating device 13 continues to operate at the first power P1 and the blower 14 continues to operate at the first speed V1 to continuously increase the temperature of the inner drum 11.

[0036] When it is determined that |T2-T3|≤ΔT1 is satisfied, step S6 is executed to control the clothes processing apparatus to enter the evaporation stage.

[0037] The current drying stage is the evaporation stage. Step S7 is executed to control the heating power of the heating device 13 to be adjusted to the second power P2, and to control the fan speed of the blower device 14 to be adjusted to the second speed V2. The second power P2 is less than the first power P1, and the second speed V2 is greater than the first speed V1. During the evaporation stage, the temperature of the inner drum 11 has already risen. If it continues to operate at the first power P1, overheating will occur and damage will occur to the clothes. Therefore, the heating power of the heating device 13 is controlled to be lowered to the second power P2. This can avoid overheating and damage to the clothes, reduce energy consumption, and achieve energy conservation and emission reduction. The fan speed of the blower device 14 is controlled to be increased to the second speed V2 to increase the hot air circulation, so as to achieve continuous evaporation of water from the surface of the load and improve the drying efficiency of the evaporation stage.

[0038] After the heating device 13 operates at the second power P2 and the blowing device 14 operates at the second speed V2, step S8 is executed to determine whether the following conditions are simultaneously met: |T1-T4|≤ΔT2, and the inlet air temperature T1 is within the first preset temperature range; if so, step S9 is executed; if not, step S10 is executed.

[0039] If it is determined that |T1-T4|≤ΔT2 is not satisfied and the inlet air temperature T1 is outside the first preset temperature range, step S10 is executed to adjust the heating power of the heating device 13 to a third power P3 and / or to adjust the impeller speed of the blower device 14 to a third speed V3. The third power P3 is less than the second power P2, the third speed V3 is greater than the second speed V2, ΔT2 is the second preset temperature difference, and the second preset temperature difference ΔT2 is less than the first preset temperature difference ΔT1, and T4 is the preset temperature control condition for the inner drum 11 during the evaporation phase, i.e., T4 is the preset temperature of the inner drum 11 during the evaporation phase, and the preset temperature control condition T4 is less than the preset temperature control condition T3. When it is determined that |T1-T4|≤ΔT2 is not satisfied and the air inlet temperature T1 is not within the first preset temperature range, it indicates that the temperature of the inner drum 11 cannot be maintained within a stable temperature range. Therefore, the heating power of the heating device 13 is controlled to be reduced to the third power P3 for continuous heating, thereby avoiding overheating and causing damage to the clothes, reducing energy consumption, and achieving energy conservation and emission reduction. And / or, the wind wheel speed of the blowing device 14 is controlled to be increased to the third speed V3 to increase the hot air circulation, so as to achieve continuous evaporation of water from the surface of the load, thereby improving the drying efficiency of the evaporation stage.

[0040] When |T1-T4|≤ΔT2 and the inlet air temperature T1 is within the first preset temperature range, step S9 is executed to determine whether the drying efficiency η is less than the preset efficiency. If so, step S11 is executed to control the clothing processing equipment to enter the volatilization stage; if not, the heating device 13 is controlled to operate at the second power P2 or the third power P3, and the blowing device 14 is controlled to operate at the second speed V2 or the third speed V3.

[0041] Among them, the drying efficiency is calculated T0 is a preset temperature value. In this embodiment, the preset efficiency is 25%. When the clothes drying efficiency η is less than 25%, step S11 is executed to control the clothes processing device to enter the volatilization stage.

[0042] If the current drying stage is the volatilization stage, step S12 is executed to control the heating power of the heating device 13 to be adjusted to a fourth power P4, and the impeller speed of the blower device 14 to be adjusted to a fourth speed V4. The fourth power P4 is less than the third power P3, and the fourth speed V4 is greater than the third speed V3. During the volatilization stage, the temperature of the inner drum 11 has already risen. If it were to operate at a higher power, overheating would occur and damage the clothes. Therefore, the heating power of the heating device 13 is controlled to be lowered to the fourth power P4. This can avoid overheating and damage to the clothes, reduce energy consumption, and achieve energy conservation and emission reduction. The impeller speed of the blower device 14 is controlled to be increased to the fourth speed V4 to increase the hot air circulation, so that moisture can move from the interior of the load to the surface for volatilization, thereby improving the drying efficiency during the volatilization stage.

[0043] After the heating device 13 operates at the fourth power P4 and the blowing device 14 operates at the fourth speed V4, step S13 is executed to determine whether the following conditions are simultaneously met: |T1-T5|≤ΔT2, and the inlet air temperature T1 is within the second preset temperature range; if so, step S14 is executed; if not, step S15 is executed.

[0044] If it is determined that |T1-T5|≤ΔT2 is not satisfied and the inlet air temperature T1 is outside the second preset temperature range, step S15 is executed to adjust the heating power of the heating device 13 to a fifth power P5 and / or to adjust the impeller speed of the air blowing device 14 to a fifth speed V5. The fifth power P5 is less than the fourth power P4, the fifth speed V5 is greater than the fourth speed V4, and T5 is the preset temperature control condition for the inner drum 11 during the volatilization phase, i.e., T5 is the preset temperature of the inner drum 11 during the volatilization phase, and the preset temperature control condition T5 is less than the preset temperature control condition T4. When it is determined that |T1-T5|≤ΔT2 is not satisfied and the air inlet temperature T1 is not within the second preset temperature range, it indicates that the temperature of the inner drum 11 cannot be maintained within a stable temperature range, and thus the heating power of the heating device 13 is controlled to be reduced to the fifth power P5 for continuous heating, thereby avoiding overheating and causing damage to the clothes, reducing energy consumption, and achieving energy conservation and emission reduction, and / or controlling the wind wheel speed of the blowing device 14 to be increased to the fifth speed V5 to increase the hot air circulation, so as to enable the moisture to move from the inside of the load to the surface and then volatilize, thereby improving the drying efficiency in the volatilization stage.

[0045] When |T1-T5|≤ΔT2 and the inlet air temperature T1 is within the second preset temperature range, step S14 is executed to determine whether the inlet air temperature T1 is equal to the return air temperature T2. If so, step S16 is executed to control the clothing processing equipment to enter the rapid cooling stage; if not, the heating device 13 is controlled to operate at the fourth power P4 or the fifth power P5, and the blowing device 14 is controlled to operate at the fourth speed V4 or the fifth speed V5.

[0046] If the current drying stage is the rapid cooling stage, step S17 is executed to control the heating device 13 to be turned off and the impeller speed of the blower device 14 to be adjusted to a sixth speed V6. The sixth speed V6 is greater than the fifth speed V5 and is the maximum impeller speed of the blower device 14. During the rapid cooling stage, the heating device 13 is turned off to stop heating the airflow, and the impeller speed of the blower device 14 is increased to the maximum impeller speed, increasing air circulation. This allows for rapid cooling of the inner drum 11 and the load, improving cooling efficiency during the rapid cooling stage and preventing user discomfort or burns caused by excessive temperatures when removing the load from the inner drum 11.

[0047] After the blower 14 operates at the sixth speed V6, step S18 is executed to determine whether T1 = T2 = T6. If so, step S19 is executed. If not, step S17 is executed to control the blower 14 to operate at the maximum impeller speed. T6 is the preset temperature control condition for the inner drum 11 during the rapid cooling stage, i.e., T6 is the preset temperature of the inner drum 11 during the rapid cooling stage, and the preset temperature control condition T6 is less than the preset temperature control condition T5.

[0048] When it is determined that T1 = T2 = T6 is satisfied, step S19 is executed to control the clothes processing device to end the drying operation.

[0049] The drying control method of the clothing processing device of this embodiment can change the heating power of the heating device 13 and the wind wheel speed of the blowing device 14 in different drying stages, so that the heating power of the heating device 13 and the wind wheel speed of the blowing device 14 are negatively correlated, which is conducive to achieving a balanced steady state of the temperature of the inner drum 11, so that the temperature of the inner drum 11 can be maintained within an appropriate range during the drying and heating process, and the drying temperature in each drying stage can be accurately controlled, which greatly shortens the drying time, thereby improving the drying efficiency, and can also minimize the damage to the clothes, and reduce energy waste and loss, thereby achieving energy saving and emission reduction.

[0050] Among them, although in step S10 and step S15, the heating power of the heating device 13 and the wind wheel speed of the blowing device 14 are not adjusted at the same time, step S10 and step S15 also have the situation of adjusting the heating power of the heating device 13 and the wind wheel speed of the blowing device 14 at the same time, and step S4, step S7, step S12 and step S17 have the situation of adjusting the heating power of the heating device 13 and the wind wheel speed of the blowing device 14 at the same time, so that the overall adjustment trend between the heating power of the heating device 13 and the wind wheel speed of the blowing device 14 is negatively correlated, that is, during the entire drying stage, the heating power of the heating device 13 is adjusted from large to small, and at the same time, the wind wheel speed of the blowing device 14 is adjusted from small to large.
