Description

Technical Field

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

[0002] During the high-speed spin-drying stage of a drum washing machine, some washing water accumulates at the bottom of the outer drum, and water and foam between the inner and outer drums can easily return to the window screen and inner drum through the gap between the inner drum and the window gasket, thus returning to the load, resulting in poor spin-drying effect.

[0003] Accordingly, a new technical solution is needed in this field to solve the above-mentioned technical problems. Summary of the Invention

[0004] The present invention aims to solve the above-mentioned technical problems, namely, to solve the problem that existing clothing processing equipment is prone to backflow of water and foam during high-speed dehydration, resulting in poor dehydration effect.

[0006] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the drainage operation includes a first drainage operation in the washing stage, a second drainage operation in the rinsing stage, and a dehydration stage.

[0007] In a preferred embodiment of the control method for the above-mentioned garment processing equipment, when the first drainage operation is started, the fan is made to execute the blowing mode; and / or, when the second drainage operation is started, the fan is made to execute the blowing mode; and / or, when the dehydration stage is started, the fan is made to execute the blowing mode.

[0008] In a preferred embodiment of the control method for the aforementioned garment processing equipment, during the first drainage operation, the blower is activated to execute the blowing mode after the inner drum rotation speed reaches a first set value; and / or, during the second drainage operation, the blower is activated to execute the blowing mode after the inner drum rotation speed reaches a second set value; and / or, during the dehydration stage, the blower is activated to execute the blowing mode after the inner drum rotation speed reaches a third set value.

[0009] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, during the dehydration stage, the remaining dehydration time is acquired in real time, and the blower is selectively activated to execute the blowing mode based on the remaining dehydration time.

[0010] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "selectively causing the fan to execute the blowing mode according to the remaining dehydration time" specifically includes: comparing the remaining dehydration time with a set time; if the remaining dehydration time is not greater than the set time, then causing the fan to execute the blowing mode; if the remaining dehydration time is greater than the set time, then not causing the fan to execute the blowing mode.

[0011] In the preferred embodiment of the control method for the above-mentioned clothing processing equipment, the step of "the fan executing the blowing mode" specifically includes: obtaining the diameter of the inner drum; obtaining the actual rotation speed of the inner drum in real time; determining the target rotation speed of the fan based on the drum diameter and the actual rotation speed; and causing the fan to rotate and run at the target rotation speed.

[0012] In a preferred embodiment of the control method for the aforementioned garment processing equipment, during the operation of the fan at the target rotation speed, the control method of the present invention further includes: acquiring the amplitude of the inner cylinder during rotation at a first time interval; calculating the difference between the amplitude acquired in the current time and the amplitude acquired in the previous time; and selectively adjusting the target rotation speed based on the difference.

[0013] In a preferred embodiment of the control method for the above-mentioned clothing processing equipment, a heater is provided in the first air duct. During the process of the blower executing the blowing mode, the control method further includes: determining whether the clothing processing equipment is in the dehydration stage; if the determination result is "yes", then the heater is activated so that the air blown out by the blower is hot air; if the determination result is "no", then the heater is not activated.

[0014] In a preferred embodiment of the control method for the aforementioned garment processing equipment, during the execution of the blowing mode by the fan, the control method further includes: determining whether the garment processing equipment is in the dehydration stage; if the determination result is "yes", then acquiring the dehydration time in real time, and selectively stopping the fan from executing the blowing mode based on the dehydration time; if the determination result is "no", then allowing the fan to continue executing the blowing mode until the drainage operation is completed.

[0015] In a second aspect, the present invention provides a garment processing device, the garment processing device including a controller, the controller being configured to execute the control method of the garment processing device described above.

[0016] When the above technical solution is adopted, the control method of the present invention, during the operation of the washing program, when the drainage operation is performed, causes the fan to execute a blowing mode. Specifically, the blowing mode is that the fan blows airflow from the front end of the inner drum into the inner drum through the first air duct and the window gasket to form a high-pressure zone at the front end of the inner drum. At the same time, the fan extracts the air between the rear end of the inner drum and the outer drum to form a low-pressure zone at the rear end of the inner drum, thereby forming an airflow from the inner drum to the outer drum. With this setting, during the drainage operation, the fan forms a high-pressure zone at the front end of the inner drum and a low-pressure zone at the rear end of the inner drum, thereby forming an airflow from the high-pressure zone to the low-pressure zone and from the inner drum to the outer drum. This airflow can prevent the washing water and foam accumulated between the inner drum and the outer drum from returning to the inner drum, thereby effectively improving the drainage efficiency, avoiding water accumulation at the bottom of the outer drum, and effectively improving the dehydration effect.

[0017] Furthermore, the drainage operation includes the first drainage operation in the washing stage, the second drainage operation in the rinsing stage, and the entire dehydration stage. This setup ensures that water is completely drained each time, thereby improving the efficiency of foam removal and effectively enhancing the rinsing effect.

[0018] Furthermore, when the drainage operation is initiated, the blower is started to execute the blowing mode, thereby accelerating the drainage speed in real time and shortening the drainage time.

[0019] Furthermore, during the drainage operation, the blower is only started to perform the blowing mode after the inner cylinder reaches the set speed. This ensures that the blower is only turned on when there is backflow of water or foam, thus avoiding prolonged operation of the blower and saving resources.

[0020] Furthermore, during the dehydration stage, the remaining dehydration time is acquired in real time, and the fan is selectively set to blow mode based on the remaining dehydration time. This setting allows the fan to blow in the latter half of the dehydration stage to accelerate the discharge of washing water, prevent washing water from accumulating at the bottom of the outer drum, and thus avoid backflow of water and foam, effectively improving the dehydration effect.

[0021] Furthermore, the step of "selectively enabling the blower to execute the blowing mode based on the remaining dehydration time" specifically includes: comparing the remaining dehydration time with the set time; if the remaining dehydration time is not greater than the set time, then enabling the blower to execute the blowing mode; if the remaining dehydration time is greater than the set time, then not enabling the blower to execute the blowing mode. This setting method simplifies the judgment process and can accurately grasp the timing of the blower's start-up, making it convenient for control and use.

[0022] Furthermore, the steps of "the fan executes the blowing mode" specifically include: obtaining the inner drum diameter; obtaining the actual rotation speed of the inner drum in real time; determining the target rotation speed of the fan based on the drum diameter and the actual rotation speed; and making the fan rotate and run at the target rotation speed. This setting method matches the rotation speed of the fan with the drum diameter and the rotation speed of the inner drum, which can accelerate the discharge of washing water to the greatest extent, avoid the accumulation of washing water at the bottom of the outer drum, and better prevent backflow and foaming.

[0023] Furthermore, during the operation of the fan, the control method also includes: acquiring the amplitude of the inner drum during rotation at set intervals; adjusting the target speed of the fan according to the amplitude; this setting method adjusts the speed of the fan by adjusting the amplitude, so that the operating state of the fan matches the current state of the inner drum, thereby improving the effect of preventing backflow of water and foam, and helping to discharge the washing water and foam more smoothly.

[0024] Furthermore, a heater is installed in the first air duct. During the blowing mode, the control method also includes: determining whether the garment processing equipment is in the dehydration stage; if the determination result is "yes", the heater is activated so that the air blown by the fan is hot air; if the determination result is "no", the heater is not activated. This setting allows the heater to operate during the dehydration stage, thereby providing hot air to the load during the dehydration process, which can improve the dehydration effect and shorten the time required for dehydration.

[0031] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0032] It should be noted that in the description of this invention, terms such as "inner," "outer," "front," and "rear," indicating directional or positional relationships, are based on the directional or positional relationships shown in the accompanying drawings. These are merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation; therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0033] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connect," and "install" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through other components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] As mentioned in the background section, existing garment processing equipment is prone to backflow of water and foam through the small holes in the window pad during high-speed dehydration, resulting in poor dehydration performance.

[0035] In the process of performing drainage operation, the control method of the garment processing equipment of the present invention creates a high-pressure zone at the front end of the inner drum and a low-pressure zone at the rear end of the inner drum by a fan. This creates an airflow from the high-pressure zone to the low-pressure zone and an airflow from the inner drum to the outer drum. The airflow prevents the washing water and foam accumulated between the inner drum and the outer drum from returning to the inner drum, thereby effectively improving drainage efficiency, avoiding water accumulation at the bottom of the outer drum, and effectively improving the dehydration effect.

[0036] Specifically, please refer to Figure 1The garment processing device of the present invention includes a housing 1 and an outer cylinder 2, an inner cylinder 3, a drive motor 4, a fan 5, a first air duct 6, a second air duct 7, and a window gasket 8 disposed within the housing 1.

[0037] The inner drum 3 is installed inside the outer drum 2 and can rotate relative to the outer drum 2. The drive motor 4 is connected to the housing 1, and the output end of the drive motor 4 is connected to the inner drum 3 so as to drive the inner drum 3 to rotate. The window gasket 8 is used to seal the housing 1 and the outer drum 2 to prevent washing water leakage.

[0038] The fan 5 is installed on the outer cylinder 2. The fan 5 is configured to draw air from its air inlet and blow air to its air outlet. The air outlet of the fan 5 is connected to the first end of the first air duct 6. The second end of the first air duct 6 is connected to the gap of the window gasket 8. The gap of the window gasket 8 is connected to the inner cylinder 3 so that the fan 5 can blow air into the inner cylinder 3 through the window gasket 8 during operation.

[0039] The air inlet of the fan 5 is connected to the first end of the second air duct 7, and the second end of the second air duct 7 is connected to the gap between the rear end of the inner cylinder 3 and the outer cylinder 2, so that the fan 5 can extract the air from the rear end of the inner cylinder 3 during operation.

[0040] It should be noted that the front end of the inner cylinder 3 is specifically the open end of the inner cylinder 3, and the rear end of the inner cylinder 3 is specifically the end of the inner cylinder 3 away from its opening.

[0041] With this configuration, during the operation of the blower 5, a high-pressure zone is formed at the front end of the inner cylinder 3 and a low-pressure zone is formed at the rear end of the inner cylinder 3. This creates an airflow from the front end to the rear end of the inner cylinder 3 and through the hole at the rear end of the inner cylinder 3 to the second end of the second air duct 7. This airflow generates a driving force during drainage, propelling the water between the inner cylinder 3 and the outer cylinder 2 to be discharged smoothly. Furthermore, the high-pressure zone at the front end of the inner cylinder 3 effectively prevents water and foam at the bottom between the inner cylinder 3 and the outer cylinder 2 from returning to the inner cylinder 3 through the opening of the window gasket 8, thus effectively improving the dehydration effect.

[0042] Preferably, please continue reading. Figure 1 The garment processing equipment of the present invention also includes a heater 9, which is installed in the first air duct 6 to heat the airflow passing through the first air duct 6, so that the airflow blown to the inner drum 3 is hot air, so as to heat the load in the inner drum 3 during the dehydration stage, improve the dehydration effect and increase the dehydration speed.

[0043] Preferably, the garment processing device of the present invention further includes a controller, which is communicatively connected to the drive motor 4, the fan 5 and the heater 9, and is configured to execute the control method of the garment processing device of the present invention.

[0044] The clothing processing equipment of the present invention can be a drum washing machine or a washer-dryer combo.

[0045] In addition, based on the structure of the above-mentioned clothing processing equipment, the present invention also provides a control method for the clothing processing equipment, so as to accelerate the discharge speed of washing water when the clothing processing equipment performs drainage operation, avoid the problem of backflow and foaming in the inner drum, and thus ensure thorough dehydration in the dehydration stage and improve the dehydration effect.

[0046] Specifically, the control method of the garment processing equipment of the present invention includes: during the operation of the washing program, when the drainage operation is performed, the fan is made to perform the blowing mode.

[0047] Specifically, in the blowing mode, the fan blows air into the inner drum from the front end through the first air duct and the window gasket to create a high-pressure zone at the front end of the inner drum. At the same time, the fan extracts the air between the rear end of the inner drum and the outer drum to create a low-pressure zone at the rear end of the inner drum, thereby forming an airflow from the inner drum to the outer drum, which accelerates the discharge of washing water and prevents the washing water between the inner drum and the outer drum from flowing back into the inner drum during the drainage process.

[0048] With the configuration of this invention, during the drainage operation, the operation of the fan creates a high-pressure zone at the front end of the inner drum and a low-pressure zone at the rear end of the inner drum. This creates airflow from the high-pressure zone to the low-pressure zone and from the inner drum to the outer drum. The airflow prevents the washing water and foam accumulated between the inner and outer drums from returning to the inner drum, thereby effectively improving drainage efficiency, preventing water accumulation at the bottom of the outer drum, and effectively improving the dehydration effect.

[0049] Preferably, the drainage operation includes a first drainage operation in the washing stage, a second drainage operation in the rinsing stage, and a dehydration stage.

[0050] With this setup, each drainage cycle ensures that all water is completely drained, thereby improving the efficiency of foam removal and effectively enhancing the rinsing effect.

[0051] It should be noted that this invention does not impose any restrictions on the starting conditions for the fan to execute the blowing mode. In practical applications, those skilled in the art can set the starting conditions for the fan to execute the blowing mode according to actual needs. For example, the fan can be started to execute the blowing mode when the garment processing equipment determines that a drainage operation is to be performed and starts; or, the fan can be started to execute the blowing mode after the inner drum reaches a certain speed during the drainage operation of the garment processing equipment. Adjustments and changes to the starting conditions for the fan to execute the blowing mode do not depart from the basic principles of this invention and should all be limited to the protection scope of this invention.

[0052] In one embodiment, when the first drainage operation is initiated, the blower is set to blow mode.

[0053] In another embodiment, when the second drainage operation is initiated, the blower is set to blow mode.

[0054] In another embodiment, when the dehydration stage is started, the blower is made to operate in a blowing mode.

[0055] By using the above settings, the fan is started to execute the blowing mode at the same time as the drainage operation is initiated, thereby speeding up the drainage process in real time and shortening the drainage time.

[0056] In a further preferred embodiment, when the dehydration stage is started, if the fan is set to blow mode, and during the blowing mode, the control method of the garment processing equipment of the present invention further includes:

[0057] S101: Determine whether the garment processing equipment is in the dehydration stage.

[0058] S102: If the judgment result is "yes", the dehydration time is obtained in real time, and the blower is selectively stopped from executing the blowing mode based on the dehydration time.

[0059] The dehydration time can be calculated by subtracting the current time from the start time of the dehydration process, or by subtracting the remaining dehydration time displayed on the screen from the preset total dehydration time.

[0060] S103: If the judgment result is "no", then the fan will continue to execute the blowing mode until the drainage operation is completed.

[0061] Specifically, the step of "selectively stopping the blower from operating in blowing mode based on the dehydration time" includes:

[0062] S1021: Determine whether the dehydration time has exceeded the preset time.

[0063] S1022: If the judgment result is "yes", then the fan will stop executing the blowing mode.

[0064] S1023: If the judgment result is "no", then the fan will continue to execute the blowing mode.

[0065] By using the above setup, the fan runs for a period of time during the dehydration stage, rather than running continuously, in order to save resources.

[0066] In one embodiment, during the first drainage operation, the blower is activated to blow air mode after the inner cylinder speed reaches a first set value.

[0067] In another embodiment, during the second drainage operation, the blower is activated to blow air mode after the inner cylinder speed reaches the second set value.

[0068] In another embodiment, during the dehydration stage, the blower is activated to blow air mode once the inner cylinder speed reaches a third set value.

[0069] It should be noted that this invention does not impose any restrictions on the specific values ​​of the first, second, and third set values. In practical applications, those skilled in the art can set the specific values ​​of the first, second, and third set values ​​according to actual needs. Preferably, the values ​​of the first, second, and third set values ​​are determined by technicians through multiple washing tests. Furthermore, the values ​​of the first, second, and third set values ​​can be the same or different. Adjustments and changes to the values ​​of the first, second, and third set values ​​do not depart from the basic principles of this invention and should be limited to the scope of protection of this invention.

[0070] With the above settings, during the drainage operation, the blower will only be started to execute the blowing mode after the inner cylinder reaches the set value. This ensures that the blower is only turned on when there is backflow of water or foam, thus avoiding prolonged operation of the blower and saving resources.

[0071] In yet another implementation, please refer to Figure 2 The controlling party of the present invention further includes:

[0072] S111: During the dehydration stage, the remaining dehydration time is obtained in real time.

[0073] S112: Selectively enable the blower to operate in blowing mode based on the remaining dehydration time.

[0074] Preferably, step S112, "selectively activating the blower in blowing mode based on the remaining dehydration time," specifically includes:

[0075] S1121: Compare the remaining dehydration time with the set time.

[0076] Determine whether the remaining dehydration time is greater than the set time. If the result is "yes", proceed to step S1123; if the result is "no", proceed to step S1122.

[0077] S1122: Enables the fan to operate in blowing mode.

[0078] If the remaining dehydration time is no more than the set time, the fan will run in blowing mode to speed up the discharge of washing water, thereby avoiding the accumulation of washing water at the bottom of the outer drum and improving the dehydration effect.

[0079] S1123: Do not enable the fan to operate in blowing mode.

[0080] If the remaining dehydration time exceeds the set time, the blower will not be activated in blowing mode.

[0081] The above-described implementation method is simple to determine, can accurately grasp the start-up timing of the fan, and is convenient for control and use.

[0082] This invention does not impose any restrictions on the specific value of the set time. In practical applications, those skilled in the art can set the set time value according to actual needs. Specifically, before the equipment leaves the factory, technicians determine the set time value through multiple batches of dehydration tests and store it in the controller. Adjustments and changes to the set time value do not deviate from the basic principles of this invention and should be limited to the protection scope of this invention.

[0083] In a preferred embodiment, please refer to Figure 3 The specific steps for "the fan to execute the blowing mode" include:

[0084] S201: Obtain the diameter of the inner cylinder.

[0085] Specifically, the inner cylinder diameter is pre-stored in the controller.

[0086] S202: Real-time acquisition of the actual rotational speed of the inner cylinder.

[0087] Specifically, the actual rotational speed of the inner cylinder is determined by obtaining the rotational speed of the drive motor, or the rotational speed of the inner cylinder is determined based on the eccentricity value of the inner cylinder and identified as the actual rotational speed. The method of obtaining and determining the actual rotational speed does not limit the scope of protection of this invention.

[0088] S203: Determine the target speed of the fan based on the cylinder diameter and the actual rotational speed.

[0089] Specifically, the controller has a pre-stored "Comparison Table of Cylinder Diameter, Inner Cylinder Speed, and Target Fan Speed". Once the cylinder diameter and the actual speed of the inner cylinder are determined, the target speed of the fan is directly determined according to the "Comparison Table". In addition, the comparison data of cylinder diameter, inner cylinder speed, and target fan speed in the "Comparison Table" were determined by technicians through multiple experiments.

[0090] S204: Make the fan rotate at the target speed.

[0091] By setting the fan speed to match the cylinder diameter and the inner cylinder speed, the washing water can be discharged more quickly, preventing washing water from accumulating at the bottom of the outer cylinder and thus better preventing backflow and foaming.

[0092] In a further preferred embodiment, during the operation of the fan at the target speed, the control method of the present invention further includes:

[0093] S205: Acquire the amplitude of the inner cylinder during rotation at the first interval.

[0094] Specifically, the amplitude of the cylinder can be monitored by an ACC accelerometer. The data detected by the ACC accelerometer is acquired every first time interval and recorded as the amplitude of the inner cylinder when it rotates.

[0095] For example, the first time can be 30 seconds.

[0096] For example, the first time can be 1 minute.

[0097] S206: Calculate the difference between the amplitude obtained in the current measurement and the amplitude obtained in the previous measurement.

[0098] S207: Based on the difference, selectively adjust the target speed. This causes the fan to rotate and operate at the adjusted target speed.

[0099] In practical applications, when the difference is 0, the target speed is not adjusted; when the difference is positive, the target speed is increased; and when the difference is negative, the target speed is decreased. Furthermore, the adjustment range of the target speed can be determined based on the absolute value of the difference. Any adjustments or changes to the specific execution steps of step S207 do not deviate from the basic principles of this invention and should be limited to the scope of protection of this invention.

[0100] Increased amplitude can lead to severe backflow. By using the above settings, the target speed of the blower can be adjusted according to the amplitude during actual operation, so that the blower's air volume matches the current state of the inner cylinder, thereby further improving the dehydration effect and preventing backflow of water and foam.

[0101] Preferably, a heater is installed in the first air duct, and the control method of the present invention further includes the following during the blowing mode of the fan:

[0102] S208: Determine whether the garment processing equipment is in the dehydration stage.

[0103] S209: If the judgment result is "yes", then the heater will be activated so that the air blown out by the fan is hot air.

[0104] S210: If the judgment result is "no", then the heater will not be operated.

[0105] This setup, which operates the heater during the dehydration stage to provide hot air to the load during dehydration, can improve the dehydration effect and shorten the time required for dehydration.

[0106] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after such changes or substitutions will all fall within the scope of protection of the present invention.
