Description

Technical Field

[0001] This invention relates to the field of clothing drying and care technology, and more specifically, to a drying control method and a clothing treatment device. Background Technology

[0002] Currently, traditional clothing drying devices, such as dryers and washer-dryer combos, generally work by heating air within the system and then introducing it into the drying drum. Under the influence of the hot air, the water on the clothes evaporates and mixes with the air to form humid air. This humid air is then exhausted through the exhaust pipe in the ventilation system, thus achieving the purpose of drying the clothes.

[0003] However, during the exhaust process, if the temperature of the humid air is much higher than that of the outside air, it will condense when it comes into contact with the outside air, forming a large amount of condensation outside the exhaust duct, which will affect the user experience. Summary of the Invention

[0004] This application is based on the inventor's discovery and understanding of the following problems and facts: During the drying process of clothes, if the humid and hot air formed after the drying airflow comes into contact with the damp clothes is not controlled, the humid and hot air will liquefy upon contact with the outside air after being rapidly discharged from the exhaust pipe, forming steam and causing steaming, which affects the customer's user experience. Therefore, there is a need for improvement.

[0032] According to an embodiment of a third aspect of the present invention, a garment processing apparatus is provided, comprising:

[0033] The garment processing device is equipped with a drying system, which includes a garment processing drum, an inner drum and an outer drum. The inner drum has an air inlet and the outer drum has an air outlet. The drying system includes an external drying airflow channel connecting the air inlet and the air outlet. The external drying airflow channel is equipped with an exhaust structure. The exhaust structure has an exhaust port that communicates with the external air of the garment processing drum and an exhaust fan that provides exhaust power for the drying airflow. In the preset drying mode of the drying system, the exhaust port discharges the drying airflow of the drying system to the outside of the garment processing drum.

[0034] The control unit includes a controller, a first detection module, and a second detection module. The first detection module detects the drying airflow parameters inside the exhaust structure, and the second detection module detects the ambient air parameters outside the exhaust structure.

[0035] In some embodiments, the discharge structure includes an air inlet channel and a vent hole. One end of the air inlet channel is connected to the outer drum of the clothes handling drum or the outer drying airflow channel, and the other end of the air inlet channel is connected to the vent hole.

[0057] Clothing handling devices can be washer-dryer combos with drying functions, or dryers, etc.

[0058] On the one hand, existing clothing processing devices first draw outside air into the air duct, then heat the air through a heater, and then guide it into the drying drum. Under the action of the hot air, the water on the clothes evaporates and forms humid air with the air. Then the humid air is discharged from the exhaust pipe in the exhaust structure to achieve the purpose of drying clothes. However, in actual use, if the temperature of the discharged humid air is higher than that of the outside air and the temperature difference between the two is large, it is easy to generate a large amount of water vapor. A large amount of water vapor gathers and rises, which is a steam phenomenon, which will affect the user experience.

[0059] Based on this, Figure 1 As shown, the drying control method of the garment processing apparatus according to an embodiment of the present invention includes:

[0060] In the preset mode of the drying system, the ambient air parameters outside the clothing processing drum 9 and the uncooled drying airflow parameters inside the drying system are obtained;

[0061] The external ambient air parameters of the clothing processing drum 9 are compared with the parameters of the uncooled drying airflow inside the drying system, and the discharge speed and / or discharge rhythm of the drying airflow discharged from the discharge port to the outside of the clothing processing drum 9 are controlled according to the comparison results.

[0062] Specifically, the ambient air parameters can be the air parameters surrounding the clothing processing drum 9, such as temperature and humidity. The drying airflow parameters can be the temperature and humidity of the drying airflow. By comparing the ambient air parameters and the drying airflow parameters, it can be determined whether a large amount of condensation will form after the drying airflow is discharged from the clothing processing device and comes into contact with the ambient air. Then, by controlling the discharge speed and / or discharge rhythm of the drying airflow, the temperature and humidity of the drying airflow after it is discharged from the drying system and comes into contact with the ambient air can be adjusted. By reducing the temperature and / or humidity of the drying airflow, condensation can be reduced or eliminated.

[0063] The drying airflow channel 7 has a certain length. The drying airflow can be cooled in the drying airflow channel, and the temperature of the drying airflow will be reduced when it reaches the exhaust structure 6. The length of the drying airflow channel 7 can be determined by the experiment. By changing the discharge speed and / or discharge rhythm of the drying airflow, the time of the drying airflow in the drying airflow channel can be increased or decreased, thereby adjusting the temperature of the drying airflow when it is discharged.

[0064] In some embodiments, the exhaust structure 6 is disposed on the outer cylinder 11 of the clothing processing cylinder or on the inlet side of the cooling section of the outer drying airflow channel 7;

[0065] The external ambient air parameters of the clothing processing tub 9 are the same as the ambient air parameters outside the exhaust structure 6.

[0066] The uncooled drying airflow parameters inside the drying system are the drying airflow parameters inside the exhaust structure 6.

[0067] Specifically, the exhaust structure 6 is the last component that the drying airflow passes through before being discharged from the clothes handling drum 9. The air in the external environment where the exhaust structure 6 is located is the external ambient air of the clothes handling drum, and the drying airflow inside the exhaust structure 6 is the uncooled drying airflow inside the drying system.

[0068] In some embodiments, the external ambient air parameters include the external ambient air temperature;

[0069] The drying airflow parameters include the drying airflow temperature;

[0070] The control of the discharge speed and / or discharge rhythm of the drying airflow discharged to the outside of the clothes processing drum 9 through the discharge port based on the comparison results includes:

[0071] If the ambient air temperature T2 is lower than or equal to the drying airflow T1, and ΔT = T1 - T2 ≥ ΔT 1设 At that time, the emission rate is reduced and / or the emission cycle is slowed down.

[0072] When comparing the parameters of the drying airflow and the ambient air, the temperatures of the two can be compared. Since the drying airflow itself is a hot and humid gas, it carries a large amount of water vapor. When the temperature difference between the two is ΔT, if ΔT is higher than a certain value, the drying airflow will produce a large amount of condensation when it meets the ambient air, which will affect the user experience. At this time, the discharge speed of the drying airflow can be reduced or the discharge cycle can be slowed down so that the drying airflow can stay in the drying system for a longer time and can be fully condensed, thereby reducing the temperature and decreasing ΔT. This will reduce or eliminate condensation when the drying airflow comes into contact with the ambient air.

[0073] In some embodiments, during the drying process, if the external temperature T2 of the exhaust structure 6 is higher than the internal temperature T1 of the exhaust structure 6, or the external temperature T2 of the exhaust structure 6 is lower than the internal temperature T1 of the exhaust structure 6, but ΔT = T1 - T2 < ΔT 1设 At that time, the emission rate is controlled to increase and / or the emission cycle is accelerated.

[0074] Specifically, if the value of ΔT is less than a certain value ΔT 1设 ΔT 1设 The temperature difference between the drying airflow and the ambient air can be calculated or set by the user based on the usage situation. The temperature difference can be small, such as 20℃, at which point condensation is less likely to occur. The discharge speed and / or discharge cycle can be appropriately increased to speed up the flow of the drying airflow and improve the drying efficiency.

[0075] In some embodiments, the external ambient air parameters include external ambient air humidity;

[0076] The drying airflow parameters include the humidity of the drying airflow;

[0077] The control of the discharge speed and / or discharge rhythm of the drying airflow discharged to the outside of the clothes processing drum 9 through the discharge port based on the comparison results includes:

[0078] If the humidity of the external ambient air d2 is greater than or equal to the humidity of the drying airflow d1, and Δd = d2 - d1 ≥ Δd 1设 At that time, the emission rate is reduced and / or the emission cycle is slowed down.

[0079] The drying airflow parameters and external environmental parameters can also include humidity. When Δd is greater than a preset parameter Δd 1设 At this time, a large amount of condensation is also easily generated. In this case, the discharge speed and / or discharge rhythm of the drying airflow can be controlled to increase the time the drying airflow spends in the drying system, allowing the drying airflow to fully condense. Δd 1设 It can be calculated or set by the user according to their usage; for example, the relative humidity can be 30%.

[0080] In some embodiments, the external ambient air parameters further include the external ambient air temperature and;

[0081] The drying airflow parameters also include the drying airflow temperature;

[0082] The control of the discharge speed and / or discharge rhythm of the drying airflow discharged to the outside of the clothes processing drum 9 through the discharge port based on the comparison results includes:

[0083] If the humidity of the ambient air d2 is less than the humidity of the drying airflow d1, compare the ambient air temperature T2 and the drying airflow temperature T1.

[0084] If the ambient air temperature T2 is lower than or equal to the drying airflow temperature T1, and also lower than or equal to the dew point temperature Tb of the drying airflow, the emission rate will decrease and / or the emission cycle will slow down.

[0085] Specifically, factors affecting condensation also include dew point temperature Tb. When the ambient air temperature T2 is lower than or equal to the drying airflow temperature T1 and lower than or equal to the dew point temperature Tb of the drying airflow, it can be determined that a large amount of condensation will occur when the drying airflow comes into contact with the ambient air. At this time, the drying airflow is discharged after being fully condensed and cooled in the drying system by reducing the discharge speed and / or slowing down the discharge cycle.

[0086] In some embodiments, if the ambient air temperature T2 is greater than or equal to the drying airflow temperature T1 and greater than the dew point temperature Tb of the drying airflow, the emission rate is increased and / or the emission cycle is accelerated.

[0087] Factors affecting condensation also include dew point temperature Tb. When the ambient air temperature T2 is greater than or equal to the drying airflow temperature T1 and greater than the dew point temperature Tb of the drying airflow, it can be determined that the drying airflow will not produce a large amount of condensation when it comes into contact with the ambient air. In this case, the drying airflow is allowed to be discharged after sufficient condensation and cooling in the drying system by reducing the discharge speed and / or slowing down the discharge cycle.

[0088] According to the drying control method of the clothing handling device of the present invention, in the preset mode of the drying system, the ambient air parameters outside the clothing handling drum 9 and the uncooled drying airflow parameters inside the drying system are obtained and compared. It is determined whether a large amount of condensation will be generated when the drying airflow is discharged to the outside and comes into contact with the ambient air. Then, the discharge speed and / or discharge rhythm of the drying airflow are adjusted according to the comparison results, so that the drying airflow can be fully condensed and cooled in the drying system before being discharged. This can avoid the drying airflow from generating a large amount of condensation after being discharged from the drum due to its high temperature and high humidity, which would affect the customer's user experience.

[0089] When the moisture content in the air exceeds the saturation concentration, water will condense. The higher the temperature, the more moisture the air can hold; conversely, the lower the temperature, the less moisture the air can hold. If it is determined that a large amount of water vapor will be generated after the drying airflow exits the drum, forming steam, the exit speed of the drying airflow should be immediately reduced. Specifically, a regulating valve can be installed in the exit channel of the drying airflow to adjust the exit speed. Alternatively, an exhaust fan 3 can be installed, and the exit speed of the drying airflow can be adjusted by changing the speed of the exhaust fan 3. When it is necessary to reduce the exit speed of the drying airflow, the speed of the exhaust fan 3 can be reduced, allowing the drying airflow to stay in the air duct inside the drum for a longer time, enabling the drying airflow to be cooled more thoroughly and condense more completely. Before the drying airflow is discharged from the drum, the temperature of the drying airflow is reduced to decrease the water vapor it carries, preventing the drying airflow from generating a large amount of water vapor and forming steam after encountering cold air upon exiting the drum, which would affect the customer's user experience.

[0090] This application also proposes a garment treatment device, which, through the above-mentioned control method, can achieve the technical effect of reducing condensation and avoiding affecting the customer experience.

[0091] like Figures 2 to 5 As shown, this application also proposes a clothing processing device, comprising: a drying system, the drying system including a clothing processing drum 9, the clothing processing drum 9 including an inner drum 10 and an outer drum 11, the inner drum 10 having an air inlet 101, the outer drum 11 having an air outlet 111, the drying system including an external drying airflow channel 7 connecting the air inlet 101 and the air outlet 111, the external drying airflow channel 7 having an exhaust structure 6, the exhaust structure 6 having an exhaust port communicating with the external air of the clothing processing drum 9 and an exhaust fan 3 providing exhaust power for the drying airflow, the exhaust port discharging the drying airflow of the drying system to the outside of the clothing processing drum 9 in a preset drying mode of the drying system;

[0092] The control unit includes a controller, a first detection module 4, and a second detection module 5. The first detection module 4 is used to detect the drying airflow parameters inside the exhaust structure 6, and the second detection module 5 is used to detect the ambient air parameters outside the exhaust structure 6. The controller controls the exhaust speed and / or exhaust rhythm of the exhaust fan 3 based on the drying airflow parameters fed back by the first detection module 4 and the ambient air parameters fed back by the second detection module 5.

[0093] Specifically, the air inlet 101 of the inner drum 10 can be directly implemented at the drum opening of the inner drum 10. The drying system sends air to the drum opening of the inner drum 10 through the door seal of the laundry handling device, sending the drying airflow into the drum. The first detection module 4 and the second detection module 5 can be temperature and humidity detection sensors, respectively, which can detect the temperature and humidity of the drying airflow and the ambient air, and feed the signals back to the controller. The controller can control the exhaust fan 3 according to the feedback signals. By adjusting the exhaust speed and / or exhaust rhythm of the exhaust fan 3, the exhaust speed of the drying airflow can be adjusted, thereby adjusting the residence time of the drying airflow in the drying system and adjusting the degree of condensation and cooling of the drying airflow, so that the drying airflow will not produce a lot of condensation when it comes into contact with the ambient air after being discharged, which would affect the user experience. Under this premise, the flow rate of the drying airflow can also be made as fast as possible to improve the drying efficiency.

[0094] In some embodiments, the discharge structure includes an air inlet channel 1 and a vent 2. One end of the air inlet channel 1 is connected to the outer drum 11 of the clothes processing drum or the outer drying airflow channel 7, and the other end of the air inlet channel 1 is connected to the vent 2. The other end of the vent 2 is the discharge port.

[0095] The flow area of ​​the vent 2 is larger than the flow area of ​​the air intake channel 1, and the exhaust fan 3 is installed on the air intake channel 1.

[0096] Specifically, the flow area of ​​the vent 2 is larger than that of the air inlet channel 1, which can prevent a large amount of drying airflow from remaining in the exhaust structure and affecting the normal exhaust function of the exhaust structure.

[0097] In some embodiments, the first detection module 4 is disposed outside the emission structure, and the second detection module 5 is disposed inside the vent 2.

[0098] The first detection module 4 and the second detection module 5 are specifically set outside the emission structure and inside the vent 2, respectively. They can detect the air parameters closest to the contact area between the drying airflow and the ambient air, making the parameter comparison results obtained by the controller more accurate.

[0099] In some embodiments, the system further includes: a fresh air intake channel 1 and an air volume regulating unit 8 disposed on the fresh air intake channel 1, the air volume regulating unit 8 being electrically connected to the controller, and the air volume regulating unit 8 being used to control the fresh air volume introduced by the fresh air intake channel 1.

[0100] Specifically, the controller can adjust the airflow control device. When the exhaust speed of the drying airflow is relatively fast, the controller can control the airflow control device to increase the air volume entering the drying airflow channel at the same time, that is, to synchronously increase the air intake speed of the drying airflow channel. When the exhaust speed of the drying airflow is relatively slow, the controller can control the airflow control device to reduce the air volume entering the drying airflow channel at the same time, that is, to synchronously reduce the air intake speed of the drying airflow channel. This can keep the air volume of the drying system at a balanced total amount, avoid the generation of negative pressure or high pressure in the drying airflow channel, which would affect the normal flow of the drying airflow and even affect the service life of the drying airflow channel.

[0101] In some embodiments, the clothing handling device includes a drying system, which includes a clothing handling drum 9. The clothing handling drum 9 includes an inner drum 10 and an outer drum 11. The inner drum 10 is provided with an air inlet 101, and the outer drum 11 is provided with an air outlet 111. The drying system includes an external drying airflow channel 7 connecting the air inlet 101 and the air outlet 111. The external drying airflow channel 7 is provided with an exhaust structure 6. The external drying airflow channel 7 and the exhaust structure 6 are optionally connected by multiple guide pipes of different lengths and / or inner diameters. The exhaust structure 6 is provided with a discharge port communicating with the external air of the clothing handling drum 9.
