[0001] The present invention belongs to the technical field of clothing treatment, and specifically provides a determination method for determining whether to clean lint, a drying device, and a clothing treatment device. Background Art
[0002] With the development of drying technology, more and more drying methods have emerged. However, no matter which drying method is used, a lint filtering device must be installed in the air duct of the drying air flow circulation to filter the lint generated during the drying of clothes and prevent the lint from entering the drying fan.
[0003] With long-term use, the lint filtering device will continuously accumulate lint. As the lint accumulates, the air duct will be blocked or the air velocity in the air duct will decrease, easily resulting in problems such as inability to dry or poor drying effect.
[0004] To solve the above technical problems, there are two technical solutions in the prior art. One is to disassemble the lint filtering device for cleaning after each drying operation or to wash the lint filtering device with water through a self-contained cleaning system. However, cleaning after each drying operation, although the effect is relatively good, has a frequent cleaning frequency, is cumbersome to operate, and wastes water resources, affecting the user experience. The other is to clean the lint filtering device after performing multiple drying operations.

[0030] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.
[0031] It should be noted that in the description of the present invention, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.
[0032] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and defined, the terms "set", "installed", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through other components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0033] Based on the problem pointed out in the background technology that the existing drying device cannot accurately grasp the timing of cleaning lint, which leads to frequent cleaning of the lint suction attachment and waste of water resources, or low drying efficiency due to long-term non-cleaning, thus affecting the user experience.
[0034] The determination method for determining whether to clean lint in the present invention includes obtaining the operating power of the drying fan in real time to obtain the actual operating power; the wind speed sensor detects the wind speed at the air outlet of the drying fan in real time to obtain the air outlet wind speed; and determines whether to clean the lint suction attachment according to the actual operating power and the air outlet wind speed. In this way, by using the actual operating power and the air outlet wind speed to determine whether to clean the lint suction attachment, the timing of cleaning lint can be accurately grasped, and the user can be reminded to clean the lint, so as to ensure the drying efficiency of the drying device and improve the user experience.
[0035] Specifically, the drying device of the present invention includes a drying fan, a lint suction attachment, and a wind speed sensor. Among them, the lint suction attachment is installed on the air outlet pipe of the drying fan. The lint suction attachment is configured to be able to adsorb lint, so as to adsorb the lint in the environment onto the lint suction attachment, and further prevent the lint from entering the interior of the drying fan through the air outlet, thereby protecting the drying fan and ensuring the drying effect. The wind speed sensor is used to detect the wind speed at the air outlet of the drying fan, so as to judge whether the air outlet pipe is blocked and the degree of blockage according to the change of the wind speed. The wind speed sensor can be installed on the air outlet pipe of the drying fan or on the drying fan, as long as the detection end of the wind speed sensor detects the wind speed at the air outlet. Here, the air outlet specifically refers to one end port of the air outlet pipe that is not directly connected to the drying fan.
[0036] The lint mentioned in this application includes but is not limited to hair, plush filaments, thread ends, and lint.
[0037] By setting a lint suction attachment on the air outlet pipe, the lint in the drying environment can be adsorbed, and further prevent the lint from entering the air outlet pipe and causing blockage of the air outlet pipe, so as to ensure the drying effect of the drying fan.
[0038] In one embodiment, the lint adsorbent is a filter - type adsorbent. Specifically, the filter - type adsorbent can be arranged inside the air outlet pipe or at the orifice of the air outlet pipe. Setting the lint adsorbent as a filter - type adsorbent can better prevent lint from entering the drying fan through the air outlet pipe, and it has a good effect of adsorbing lint. At the same time, in this embodiment, the detection point of the wind speed sensor is located on the side of the lint adsorbent away from the inside of the drying fan.
[0039] In one embodiment, the filter - type adsorbent is fixedly connected to the orifice of the end of the air outlet pipe facing away from the drying fan. In the case of fixed connection, when the filter - type adsorbent needs to be cleaned, the air outlet pipe can be removed and rinsed as a whole to clean the lint adsorbed on the lint adsorbent, or the air outlet pipe does not need to be removed, and the filter - type adsorbent can be directly cleaned by soaking, washing or sweeping.
[0040] In another embodiment, the filter - type adsorbent is detachably connected to the air outlet pipe (for example: fixed to the air outlet pipe through a buckle). In the case of detachable connection, the filter - type adsorbent can be removed and cleaned separately, which is more convenient for cleaning. Specifically, the filter - type adsorbent can be detachably installed inside the air outlet pipe or at the orifice of the air outlet pipe.
[0041] It should be noted that the present application does not impose any restrictions on the specific connection method between the lint adsorbent and the air outlet pipe, as long as the lint adsorbent can be replaced or cleaned. In practical applications, those skilled in the art can set the connection method between the lint adsorbent and the air outlet pipe according to actual needs. The specific implementation forms of the connection methods between the lint adsorbent and the air outlet pipe in the above - mentioned embodiments should not limit the protection scope of the present application.
[0042] In another embodiment, the lint adsorbent is a first lint sticker, and the first lint sticker is pasted on the inner wall of the air outlet pipe.
[0043] In yet another embodiment, the lint adsorbent is a second lint sticker, and the second lint sticker is pasted on the outer wall of the air outlet pipe.
[0044] In yet another embodiment, the lint adsorbent includes a first lint sticker and a second lint sticker. The first lint sticker is pasted on the inner wall of the air outlet pipe, and the second lint sticker is pasted on the outer wall of the air outlet pipe.
[0045] It should also be noted that the present application does not impose any restrictions on the specific structure of the lint adsorbent and the installation position of the lint adsorbent, as long as the installed lint adsorbent can filter and adsorb lint. In practical applications, those skilled in the art can set the specific structure of the lint adsorbent and its installation position according to actual needs. The specific implementation forms of the lint adsorbent in the above - mentioned embodiments should not limit the protection scope of the present application.
[0046] Specifically, please refer to Figure 1 , during the operation of the drying fan, the method for determining whether to clean the lint specifically includes the following steps:
[0047] S1: Obtain the operating power of the drying fan in real time to get the actual operating power.
[0048] During the operation of the drying fan, obtain the operating power of the drying fan in real time, that is, update the actual operating power in real time, so as to judge in real time whether it is necessary to clean the lint suction attachment according to the updated actual operating power.
[0049] S2: The wind speed sensor detects the wind speed at the air outlet of the drying fan in real time to get the outlet wind speed.
[0050] During the operation of the drying fan, the wind speed sensor detects the wind speed at the air outlet of the drying fan in real time, that is, updates the outlet wind speed of the air duct in real time, so as to judge in real time whether it is necessary to clean the lint suction attachment according to the updated outlet wind speed. Among them, the air outlet is specifically the end port of the air duct that is not directly connected to the drying fan.
[0051] S3: Judge whether it is necessary to clean the lint suction attachment according to the actual operating power and the outlet wind speed.
[0052] Judge whether it is necessary to clean the lint suction attachment according to the actually updated operating power and the actually updated outlet wind speed, and make a judgment in real time during the operation of the drying fan, so as to improve the accuracy of the judgment.
[0053] The present invention judges whether it is necessary to clean the lint suction attachment through the actual operating power and the outlet wind speed, can accurately grasp the timing of cleaning the lint, so as to remind the user to clean the lint, thereby ensuring the drying efficiency of the drying device and improving the user experience.
[0054] It should be noted that this application does not impose any restrictions on the specific implementation steps of step S3. As long as it is determined whether the lint suction attachment needs to be cleaned according to the actual operating power and the air outlet wind speed, those skilled in the art can set the specific implementation steps of step S3 according to actual needs in practical applications. For example, during the operation of the drying fan at the standard power, by comparing the air outlet wind speed with the preset wind speed in real time, and based on the comparison result of the air outlet wind speed and the preset wind speed, it is determined whether the lint suction attachment needs to be cleaned; or, the actual operating power can be adjusted according to the magnitude of the air outlet wind speed until the air outlet wind speed is equal to the preset wind speed, and then by comparing the actual operating power with the standard power in real time, and based on the comparison result of the actual operating power and the standard power, it is determined whether the lint suction attachment needs to be cleaned, and so on. Such adjustments and changes to the specific implementation steps of step S3 do not deviate from the basic principle of this application and should all be limited within the protection scope of this application.
[0055] The following will specifically illustrate the determination method for determining whether to clean lint in this application through several specific embodiments.
[0056] Example 1
[0057] Please refer to Figure 2 , during the operation of the drying fan, the determination method for determining whether to clean lint in this embodiment specifically includes the following steps:
[0058] S1: Obtain the operating power of the drying fan in real time to obtain the actual operating power.
[0059] During the operation of the drying fan, obtain the operating power of the drying fan in real time, that is, update the actual operating power in real time so as to be able to make a judgment in real time.
[0060] S2: The wind speed sensor detects the wind speed at the air outlet of the drying fan in real time to obtain the air outlet wind speed.
[0061] During the operation of the drying fan, the wind speed sensor detects the wind speed at the air outlet of the drying fan in real time, that is, updates the air outlet wind speed of the air outlet pipe in real time so as to be able to make a judgment in real time.
[0062] S31: Determine whether the air outlet wind speed is less than the preset wind speed.
[0063] Compare the air outlet wind speed with the preset wind speed so as to determine whether to increase the operating power of the drying fan according to the comparison result of the air outlet wind speed and the preset wind speed.
[0064] Among them, the preset wind speed is specifically the wind speed at the outlet of the air duct of the drying fan when the air duct of the drying fan is not blocked and the drying fan operates at the standard power. Its specific value is determined through experiments, and the value of the preset wind speed is stored in the controller or storage medium of the device before leaving the factory.
[0065] Specifically, the step of "judging whether to increase the operating power of the drying fan according to the comparison result between the outlet wind speed and the preset wind speed" specifically includes: if the outlet wind speed is less than the preset wind speed, then execute step S32 to increase the operating power of the drying fan until the outlet wind speed is not less than the preset wind speed; if the outlet wind speed is not less than the preset wind speed, then execute step S33 and do not increase the operating power of the drying fan.
[0066] S32: Increase the operating power of the drying fan.
[0067] In the case where the outlet wind speed is less than the preset wind speed, increase the operating power of the drying fan to increase the outlet wind speed until the outlet wind speed is not less than the preset wind speed, so that the outlet wind speed at the air duct reaches the preset wind speed.
[0068] S33: If the outlet wind speed is not less than the preset wind speed, then do not increase the operating power of the drying fan.
[0069] In the case where the outlet wind speed is not less than the preset wind speed, do not increase the operating power of the drying fan, indicating that the outlet wind speed of the drying fan at this time meets the normal drying requirements.
[0070] S34: Judge whether the current actual operating power is greater than the standard power.
[0071] Compare the current actual operating power with the standard power, so as to judge whether it is necessary to clean the lint suction accessory according to the comparison result between the current actual operating power and the standard power.
[0072] Among them, the standard power is the power value stored in advance in the controller or storage medium of the device. Generally, the standard power is the power at which the drying fan can operate normally, and the standard power is less than or equal to the rated power of the drying fan.
[0073] In addition, the current actual operating power is specifically the latest obtained operating power of the drying fan, and it is also the latest obtained operating power of the drying fan in the case where the outlet wind speed is not less than the preset wind speed.
[0074] Specifically, the step of "judging whether it is necessary to clean the lint suction accessory according to the comparison result between the current actual operating power and the standard power" specifically includes: if the current actual operating power is greater than the standard power, then execute step S35 and it is necessary to clean the lint suction accessory; if the current actual operating power is not greater than the standard power, then execute step S36 and it is not necessary to clean the lint suction accessory.
[0075] S35: It is necessary to clean the lint suction accessory and give an alarm to remind the user to clean the lint suction accessory.
[0076] When the current actual operating power is greater than the standard power, it indicates that there is a blockage at the air outlet pipe. Long-time high-power operation will damage the equipment. It is necessary to clean the lint suction accessory and give an alarm at the same time to remind the user that the lint suction accessory needs to be cleaned, so as to end the drying program in time or replace or clean the lint suction accessory after the normal end of the drying program.
[0077] It should be noted that this application does not limit any alarm method and alarm timing for giving an alarm. It can be set to give an alarm after the drying program ends. The alarm method can be text flashing or character flashing on the display screen, or it can be a sound alarm; in practical applications, those skilled in the art can choose a suitable alarm method and alarm timing according to actual needs and convenience.
[0078] S36: It is not necessary to clean the lint suction accessory.
[0079] When the current actual operating power is not greater than the standard power, it indicates that there is no blockage at the air outlet pipe for the time being or the lint adsorbed in the lint suction accessory does not affect the normal air outlet. The drying effect of the drying device is good, and there is no need to clean the lint suction accessory.
[0080] In the determination method of this embodiment, by controlling the air outlet speed of the air outlet pipe to be not less than the preset speed, and then comparing the actual operating power with the standard power, according to the size of the actual operating power relative to the standard power, it is judged whether it is necessary to clean the lint suction accessory. The judgment process is simple, the result is accurate and convenient to control.
[0081] Example 2
[0082] Please refer to Figure 3 , during the operation of the drying fan, the determination method for determining whether to clean the lint specifically includes the following steps:
[0083] S1: Obtain the operating power of the drying fan in real time to get the actual operating power.
[0084] During the operation of the drying fan, obtain the operating power of the drying fan in real time, that is, update the actual operating power in real time, so as to be able to make a judgment in real time.
[0085] S2: The wind speed sensor detects the wind speed at the air outlet of the drying fan in real time to get the air outlet speed.
[0086] During the operation of the drying fan, the wind speed sensor continuously detects the wind speed at the air outlet of the drying fan's air duct, that is, the air outlet wind speed of the air duct is updated in real time to enable real-time judgment.
[0087] S31: Determine whether the actual operating power is equal to the standard power.
[0088] Compare the actual operating power with the standard power to determine whether to adjust the operating power of the drying fan based on the comparison result of the actual operating power and the standard power.
[0089] Among them, the standard power is the power value stored in advance in the device's controller or storage medium. Generally, the standard power is the power at which the drying fan can operate normally, and the standard power is less than or equal to the rated power of the drying fan.
[0090] Specifically, the step of "determining whether to adjust the operating power of the drying fan based on the comparison result of the actual operating power and the standard power" specifically includes: if the actual operating power is not equal to the standard power, then execute step S32 to adjust the operating power of the drying fan until the actual operating power is equal to the standard power; if the actual operating power is equal to the standard power, then execute step S33 without adjusting the operating power of the drying fan.
[0091] S32: Adjust the operating power of the drying fan.
[0092] In the case where the actual operating power is not equal to the standard power, adjust the operating power of the drying fan to change the value of the actual operating power. Specifically, if the actual operating power is greater than the standard power, then reduce the operating power of the drying fan until the actual operating power is equal to the standard power; if the actual operating power is less than the standard power, then increase the operating power of the drying fan until the actual operating power is equal to the standard power.
[0093] S33: Do not adjust the operating power of the drying fan.
[0094] In the case where the actual operating power is equal to the standard power, do not adjust the operating power of the drying fan.
[0095] S34: Determine whether the current air outlet wind speed is less than the preset wind speed.
[0096] Compare the current air outlet wind speed with the preset wind speed to determine whether it is necessary to clean the lint suction accessory according to the comparison result of the current air outlet wind speed and the preset wind speed.
[0097] Among them, the preset wind speed is specifically the air outlet wind speed of the air duct when the drying fan operates at the standard power under the condition that the air duct of the drying fan is not blocked. Its specific value is determined through experiments and stored in the device's controller or storage medium before leaving the factory.
[0098] In addition, the current air outlet wind speed is the wind speed at the air outlet of the drying fan detected most recently, that is, the wind speed at the air outlet of the drying fan detected most recently under the condition that the actual operating power is equal to the standard power.
[0099] Specifically, the step of "judging whether the lint suction accessory needs to be cleaned according to the comparison result between the current air outlet wind speed and the preset wind speed" specifically includes: if the current air outlet wind speed is less than the preset wind speed, then execute step S35, and the lint suction accessory needs to be cleaned; if the current air outlet wind speed is not less than the preset wind speed, then execute step S36, and the lint suction accessory does not need to be cleaned.
[0100] S35: The lint suction accessory needs to be cleaned, and an alarm is issued to remind the user to clean the lint suction accessory.
[0101] In the case where the current air outlet wind speed is less than the preset wind speed, it indicates that there is a blockage at the air outlet pipe, the air outlet wind speed is small, and the drying effect is not good. The lint suction accessory needs to be cleaned, and an alarm is issued at the same time to remind the user to clean the lint suction accessory, so as to end the drying program in time or replace or clean the lint suction accessory after the drying program runs normally to completion.
[0102] It should be noted that the present application does not impose any restrictions on the alarm method and alarm timing for issuing the alarm. It can be set to alarm after the drying program ends. The alarm method can be text flashing or character flashing on the display screen, or it can be a sound alarm; in actual applications, those skilled in the art can select a suitable alarm method and alarm timing according to actual needs and convenience.
[0103] S36: The lint suction accessory does not need to be cleaned.
[0104] In the case where the current air outlet wind speed is not less than the preset wind speed, it indicates that there is no blockage at the air outlet pipe for the time being, or the lint adsorbed in the lint suction accessory does not affect the normal air outlet, and the drying effect of the drying device is good, so there is no need to clean the lint suction accessory.
[0105] The determination method of this embodiment controls the drying fan to operate at the standard power, and then compares the air outlet wind speed with the preset wind speed, so as to judge whether the lint suction accessory needs to be cleaned according to the magnitude of the air outlet wind speed relative to the preset wind speed. The judgment process is simple, the result is accurate and convenient to control.
[0106] Example 3
[0107] Please refer to Figure 4 and Figure 5 , on the basis of the above-mentioned Embodiment 1 and Embodiment 2, before executing step S36 "the lint suction accessory does not need to be cleaned", the determination method for determining whether to clean the lint in this embodiment further includes the following steps:
[0108] S41: Obtain the usage time of the lint suction attachment.
[0109] The usage time is the time period from the last cleaning of the lint suction attachment up to the present. Among them, each time the lint suction attachment is disassembled, the device will collect a time information and record it as the initial time; the difference between the current time and the initial time is the usage time.
[0110] When the device collects the replacement time of the lint suction attachment, that is, the initial time, it can be input manually through the mobile phone APP, or a sensor can be set at the air outlet pipe. The sensor can detect whether there is a lint suction attachment installed on the air outlet pipe. Taking the detection of no lint suction attachment as a node, record the time of this node as the initial time.
[0111] S42: Obtain the current season.
[0112] S43: Obtain the set time corresponding to the current season.
[0113] Specifically, the set time corresponding to different seasons can be determined through the "Season and Set Time Comparison Table". This "Season and Set Time Comparison Table" is stored in the controller or storage medium of the device and can be directly called.
[0114] Different seasons correspond to different set times. Exemplarily, the set time corresponding to spring is 200h, the set time corresponding to summer is 300h, the set time corresponding to autumn is 200h, and the set time corresponding to winter is 150h.
[0115] S44: Determine whether the usage time is less than the set time.
[0116] Compare the usage time with the set time, so as to judge whether to execute "Determine that the lint suction attachment does not need to be cleaned" according to the comparison result of the usage time and the set time.
[0117] Specifically, the step of "judging whether to execute 'Determine that the lint suction attachment does not need to be cleaned' according to the comparison result of the usage time and the set time" specifically includes: if the usage time is less than the set time, then execute "Determine that the lint suction attachment does not need to be cleaned", that is, execute step S36; if the usage time is not less than the set time, then do not execute "Determine that the lint suction attachment does not need to be cleaned", and execute "Determine that the lint suction attachment needs to be cleaned", that is, execute step S35.
[0118] The determination method of this embodiment further determines whether the usage time is less than the set time. If the usage time is less than the set time, "no need to clean the lint suction accessory" is executed. If the usage time is not less than the set time, "need to clean the lint suction accessory" is executed. This setting method enables the lint suction accessory to be cleaned or replaced after the set usage time, which can avoid mildew of lint or dust adsorbed on the lint suction accessory, thereby preventing pollution of clothes, maintaining the cleanliness and hygiene of clothes, and improving the user experience.
[0119] Although in this embodiment, the usage time is directly compared with the set time, this should not limit the protection scope of this application. In practical applications, other comparison and judgment methods can also be adopted. For example, the usage time and the set time are subtracted to obtain a time difference, and the judgment is made according to the size of the time difference; or, the usage time and the set time are subtracted to obtain a time difference, and the time difference is compared with a set difference, and the judgment is made according to the comparison result of the two, and so on. Such adjustments and changes in the specific methods of judging and comparing the usage time and the set time do not deviate from the basic principle of this application and should all be limited within the protection scope of this application.
[0120] Of course, it is preferred to directly compare the usage time with the set time in this embodiment, which has fewer operation steps, faster reaction speed, and is more convenient to control.
[0121] In a second aspect, this application also provides a drying device, which includes a controller configured to be able to execute the determination method of determining whether to clean lint in any of the above embodiments.
[0122] In a third aspect, this application also provides a clothing treatment device, which includes the drying device provided in the second aspect.
[0123] In a fourth aspect, this application also provides a clothing treatment device, which includes a drying device and a controller configured to be able to execute the determination method of determining whether to clean lint in any of the above embodiments.
[0124] Among them, the clothing treatment devices in the third aspect and the fourth aspect can be devices such as a dryer, a washing and drying integrated machine, and a clothes drying rack.
[0125] So far, the technical solution of the present invention has been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present invention is obviously not limited to these specific embodiments. Without departing from the principle of the present invention, those skilled in the art can make equivalent changes or substitutions to relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of the present invention.
