Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of clothes drying, in particular to a drying judgment method of clothes treatment device and clothes treatment device. BACKGROUND

[0002] The existing clothes treatment device, such as clothes dryer, washing and drying integrated machine, etc., when executing the drying program, one way is to need the user to set the temperature and the drying time, and then the washing machine automatically dries according to the set temperature and time, but the drying process is not intelligent enough, and the drying temperature and time cannot be modified according to the actual situation of the clothes, resulting in that the drying effect of the clothes is not ideal, and there is a possibility of over-drying and insufficient drying; with the design of the drying program being more intelligent, the existing drying program can autonomously judge the drying degree, and adjust the drying temperature and time in real time according to the drying degree, so as to achieve the technical purpose of adjusting in real time according to the actual situation of the clothes and improving the drying effect.

[0003] The intelligent drying judgment method mainly includes: humidity detection, temperature detection and detection of the resistance value of the metal in contact with the clothes. Among them, the temperature detection method, for example, judges the amount of clothes to be dried by detecting the temperature of the exhaust air or the drum through the temperature sensor, and then modifies the drying time in real time according to the amount of clothes to be dried, but in this temperature detection method, if the amount of clothes is small and the water content is large, the amount of clothes will be judged to be large according to the temperature method, resulting in that the drying time is modified too long, and there is a possibility of over-drying; the humidity detection chamber, for example, judges the drying degree of the clothes by detecting the humidity of the exhaust air or the drum through the humidity sensor, and modifies the drying time and / or the drying temperature in real time according to the drying degree, but in this humidity detection method, when the drying is close to the end, the humidity changes little, and the drying degree is not accurately judged, so there is a possibility of over-drying or insufficient drying; the detection of the resistance value of the metal in contact with the clothes, for example, installs a metal stirring block in the drum, the metal stirring block is in contact with the clothes, and the drying degree of the clothes is judged by measuring the resistance value of the metal stirring block, but this method can only judge the drying degree of the surface of the clothes, and cannot accurately judge the drying degree of the middle part or the clothes in a group.

[0037] The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without any creative effort are within the protection scope of the present application.

[0040] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0041] The drying judgment method for clothing processing devices proposed in this invention aims to provide an automatic method for judging the degree of drying in the drying process of clothing processing devices such as dryers and washer-dryer combos. It does not rely on components such as humidity sensors and temperature sensors, but combines the feedback power and load current of variable frequency electric fans to achieve monitoring, ensuring the drying effect while reducing the manufacturing cost of clothing processing devices.

[0042] like Figure 1 As shown, the drying control method of the garment processing device proposed in this invention includes the following steps:

[0043] Step S1: Start the drying program.

[0044] Users set or select parameters such as drying temperature and the material of the clothes to be dried, and start the drying program. After the drying program starts, the clothes handling device can obtain the weight of the clothes to be dried through a pressure sensor, or by driving the drum to rotate, and using centrifugal force to perform fuzzy weighing of the clothes to be dried.

[0045] Step S2: Start the monitoring process to monitor the power and load current of the variable frequency fan motor.

[0046] After the garment handling device starts the drying program, it initiates a monitoring process, which detects the power and load current fed back by the variable frequency fan motor.

[0047] Step S3: Determine the drying stage of the clothes based on the power changes of the variable frequency fan motor and the fluctuation range of the load current.

[0048] This invention is based on the characteristic that variable frequency fan motors can provide feedback on power and load current. It determines the drying stage of clothes by monitoring the power changes of the variable frequency fan motor and the fluctuation range of the load current. It eliminates the need to add additional temperature sensors, humidity sensors and other devices to determine the degree of drying, thus ensuring functionality while reducing the manufacturing cost of the clothes processing device.

[0049] like Figure 2 As shown, in the initial drying stage after the clothing processing device starts the drying program, the temperature of the clothes is relatively low and is in the heating stage. The drying efficiency is relatively low at this stage, and the clothes are relatively damp. At first, they will stick together tightly, but as they continue to tumble, they will become more and more even. The power will drop significantly. At this stage, the variable frequency fan needs to circulate more air, so the variable frequency fan motor does more work, and the current and power of the variable frequency fan motor are both larger. At the same time, the load current fluctuates greatly during this period.

[0050] During the middle stage of drying, the temperature of the clothes is relatively high, and the clothes are relatively fluffy. The variable frequency fan needs to circulate relatively less air, and the work done by the variable frequency fan motor is relatively reduced. At this time, the drying efficiency is high, but the temperature of the clothes will not change significantly, and the condition of the clothes will not change significantly. The heat is mainly used to dry the moisture, so the power is basically stable. However, due to the large fluctuations in the circulating air, the load current fluctuates significantly.

[0051] Towards the end of the drying process, the clothes are generally quite dry, with very little moisture remaining. The drying efficiency is low, the temperature of the clothes continues to rise, and the clothes become increasingly fluffy. Therefore, the inverter fan motor does less work during this stage and is in a slow decline phase. However, the fluctuation of the circulating air is small, resulting in a smaller fluctuation in the load current.

[0052] Based on the above analysis, it can be determined which stage of the drying process is in. The variable frequency fan motor is an indispensable component of the variable frequency air conditioner. This invention combines existing components to realize the determination of the drying stage, without the need to add additional sensors or other components to determine the degree of drying, thus ensuring functionality while reducing the manufacturing cost of the clothing processing device.

[0053] The drying judgment method of the clothing treatment device proposed in this invention will be described in detail below with several specific embodiments.

[0054] Example 1

[0055] This embodiment provides a method for determining the drying time of a clothes dryer, including the following steps:

[0056] Step S31: The user starts the drying program.

[0057] Users set or select parameters such as drying temperature and the material of the clothes to be dried, and start the drying program. After the drying program starts, the dryer can obtain the weight of the clothes to be dried through a pressure sensor, or by driving the drum to rotate and using centrifugal force to perform fuzzy weighing of the clothes to be dried.

[0058] Step S32: Start the monitoring process to monitor the power and load current of the variable frequency fan motor.

[0059] After the dryer starts the drying program, it initiates a monitoring process, which detects the power and load current fed back by the inverter fan motor.

[0060] Step S33: From the start of the drying program, if the power drop exceeds the first set range and the load current fluctuation exceeds the set fluctuation range, the drying program is determined to be in the initial drying stage.

[0061] In the initial drying stage after the dryer starts the drying program, the temperature of the clothes is relatively low and is in the heating stage. The drying efficiency is relatively low at this stage, and the clothes are still quite damp. At first, they will stick together tightly, but as they are tumbled, they will become more and more even. The power consumption will drop significantly. During this stage, the inverter fan needs to circulate more air, so the inverter fan motor does more work, and the current and power of the inverter fan motor are both higher. At the same time, the load current fluctuates significantly.

[0062] Therefore, in this embodiment, a first preset value A is set for the power. When the power drops from the value B at the start of the drying program to BA, it is considered that the power has dropped significantly. A preset fluctuation range is set for the fluctuation range of the load current. If the fluctuation range of the load current exceeds the preset fluctuation range, it is considered that the fluctuation range of the load current is large.

[0063] Step S34: Starting from the initial drying stage, when the power is maintained within a stable range and the fluctuation of the load current exceeds the set fluctuation range, the drying program is judged to be in the intermediate drying stage.

[0064] During the middle stage of drying, the temperature of the clothes is relatively high, and the clothes are relatively fluffy. The variable frequency fan needs to circulate relatively less air, and the work done by the variable frequency fan motor is relatively reduced. At this time, the drying efficiency is high, but the temperature of the clothes will not change significantly, and the condition of the clothes will not change significantly. The heat is mainly used to dry the moisture, so the power is basically stable. However, due to the large fluctuations in the circulating air, the load current fluctuates significantly.

[0065] The power in the embodiment is maintained in a stable range, which is considered as the fluctuation range of the power is in a preset range, so that the power change is considered as a stable state as a whole.

[0066] In combination with the preset fluctuation range in step S33, when the fluctuation range of the load current exceeds the preset fluctuation range, the fluctuation range of the load current is considered as large.

[0067] Step S35: From the middle drying stage, when the power drops by more than the second set value and the fluctuation range of the load current is in the preset fluctuation range, it is determined that the drying program is in the final drying stage.

[0068] In the final drying stage, the clothes are generally dry, and the remaining moisture in the clothes is very small, so the drying efficiency is low, the temperature of the clothes is rising, and the clothes are becoming more and more fluffy, so the work of the variable frequency fan motor is less, and it is in a slow decline stage, but the fluctuation of the circulating air is small, resulting in a small fluctuation range of the load current.

[0069] Therefore, the embodiment presets a second set value C for the power, and when the power drops from the middle drying stage D to D-C, it is considered that the power is slowly declining.

[0070] In combination with the preset fluctuation range in step S33, when the fluctuation range of the load current exceeds the preset fluctuation range, the fluctuation range of the load current is considered as large.

[0071] Implementation two

[0072] The embodiment provides a drying judgment method for a washing and drying integrated machine, including the following steps:

[0073] Step S41: The user starts the washing and drying integrated program.

[0074] The user sets or selects the washing temperature, washing mode, drying temperature, material of the drying clothes and other parameters, and starts the washing and drying integrated program, and first executes the washing program. After the washing program is started, the washing and drying integrated machine can obtain the weight of the drying clothes through the pressure sensor, or perform fuzzy weighing on the weight of the drying clothes based on the centrifugal force by driving the drum to rotate.

[0075] Step S42: Execute the washing program until the washing is completed.

[0076] This part of the washing control can be performed according to any one of the existing washing control modes, and the embodiment is not limited in detail.

[0077] Step S43: Start the drying program and start the monitoring process to monitor the power and load current of the variable frequency fan motor.

[0078] After the all-in-one washing and drying machine starts the drying program, a monitoring process is started, which is used to detect the power feedback of the variable frequency fan motor and the load current.

[0079] Step S44: From the start of the drying program, when the power drops by more than a first set range and the fluctuation amplitude of the load current exceeds a set fluctuation range, it is determined that the drying program is in the initial drying stage.

[0080] In the initial drying stage of the all-in-one washing and drying machine after starting the drying program, the clothes temperature is relatively low and in the heating stage. The drying efficiency is relatively low in this stage, and the clothes are in a relatively humid stage. At the beginning, they will be tightly attached together, and with continuous tumbling, they will become more and more uniform. The power will have a significant drop. The variable frequency fan needs more circulating air, so the variable frequency fan motor works more, and the current and power of the variable frequency fan motor are larger. At the same time, the fluctuation amplitude of the load current is larger.

[0081] Therefore, in this embodiment, a first set value A is set for the power. When the power drops from the value B at the start of the drying program to B-A, it is considered that the power has a significant drop. A set fluctuation range is set for the fluctuation amplitude of the load current. When the fluctuation amplitude of the load current exceeds the set fluctuation range, it is considered that the fluctuation amplitude of the load current is larger.

[0082] Step S45: From the initial drying stage, when the power is maintained within a stable range and the fluctuation amplitude of the load current exceeds the set fluctuation range, it is determined that the drying program is in the middle drying stage.

[0083] In the middle drying stage, the clothes temperature is relatively high, and the clothes and clothes are relatively loose. The variable frequency fan needs relatively less circulating air, and the variable frequency fan motor works relatively less. At this time, the drying efficiency is high, but the clothes temperature does not change greatly, and the clothes state does not change significantly. The heat is mainly used to complete the moisture drying, so the power is basically maintained stable. However, due to the large fluctuation of the circulating air during the period, the fluctuation amplitude of the load current is large.

[0084] In this embodiment, the power is maintained within a stable range, which is considered as the fluctuation amplitude of the power within a preset range, so that the power change is considered as a stable state as a whole.

[0085] In combination with the set fluctuation range in step S44, when the fluctuation amplitude of the load current exceeds the set fluctuation range, it is considered that the fluctuation amplitude of the load current is larger.

[0086] Step S46: From the middle drying stage, when the power drops by more than a second set value and the fluctuation amplitude of the load current is within the set fluctuation range, it is determined that the drying program is in the final drying stage.

[0087] At the end of the drying stage, the clothes are generally dry, and the remaining moisture in the clothes is very small, so the drying efficiency is low. The temperature of the clothes is rising, and the clothes are becoming more and more fluffy, so the work of the variable frequency fan motor is less, and it is in the slow decline stage, but the fluctuation of the circulating air is small, resulting in a small fluctuation range of the load current.

[0088] Therefore, in this embodiment, a second setting value C is set for the power. When the power D decreases to D-C from the middle drying stage, it is considered that the power is slowly decreasing.

[0089] In combination with the preset setting fluctuation range in step S44, the fluctuation range of the load current is within the setting fluctuation range, and it is considered that the fluctuation range of the load current is small.

[0090] Step S47: Obtain the weight information of the drying clothes.

[0091] After it is judged that the drying program enters the end drying stage, this embodiment provides a means to control the drying time of the end drying stage. The drying time of the end drying stage is associated with the weight of the drying clothes, so that the drying is adapted to the actual situation of the clothes, and the drying time is adaptively adjusted to avoid insufficient drying or over-drying.

[0092] Step S48: Determine the first running time of the end drying stage based on the weight of the drying clothes.

[0093] In this embodiment, the weight of the drying clothes is stored after the user sets the washing parameters and the drying parameters in step S41, and is read in this step.

[0094] Step S49: Control the drying program to stop after the first running time is reached.

[0095] After the drying program enters the end drying stage, the first running time of the end drying stage is controlled according to the first running time calculated in step S48. After the first running time is reached, the drying program is controlled to end.

[0096] Embodiment three

[0097] This embodiment is based on the basis of embodiment two, and the difference is that after entering the end drying stage, this embodiment provides a second means to control the drying time of the end drying stage. The drying time of the end drying stage is associated with the drying temperature of the drying program, and the drying time is adaptively adjusted to avoid insufficient drying or over-drying.

[0098] Specifically, as shown in Figure 5 , the following steps are included:

[0099] Step S51: The user starts a washing and drying integrated program.

[0100] Step S52: execute the washing program until completion of the washing.

[0101] Step S53: start the drying program, and start the monitoring process to monitor the power and the load current of the variable frequency fan motor.

[0102] Step S54: from the start of the drying program, when the power drops more than a first set range, and the fluctuation amplitude of the load current exceeds a set fluctuation range, it is judged that the drying program is in the initial drying stage.

[0103] Step S55: from the initial drying stage, when the power is maintained within a stable range, and the fluctuation amplitude of the load current exceeds the set fluctuation range, it is judged that the drying program is in the middle drying stage.

[0104] Step S56: from the middle drying stage, when the power drops more than a second set value, and the fluctuation amplitude of the load current is within the set fluctuation range, it is judged that the drying program is in the final drying stage.

[0105] Step S57: obtain the drying temperature of the drying program.

[0106] In this embodiment, the drying temperature of the drying program is set and stored in the drying parameter set by the user in step S51, and is read in this step, or is the drying temperature when the drying program enters the final drying stage according to the weight, material, etc. of the drying clothes during the drying process of the drying program.

[0107] Step S58: determine the second running time of the final drying stage based on the drying temperature.

[0108] Step S59: control the drying program to stop after the second running time is reached.

[0109] When the drying program enters the final drying stage, this embodiment controls the running time of the final drying stage according to the second running time calculated in step S58, and controls the drying program to end after the second running time is reached.

[0110] Embodiment Four

[0111] This embodiment is based on the basis of embodiment two or three, the difference is that after entering the final drying stage, this embodiment provides a third means to control the drying time of the final drying stage, associates the final drying time with the material of the drying clothes, makes the drying fit the actual situation of the clothes, and adaptively adjusts the drying time to avoid insufficient drying or over-drying.

[0112] Specifically, as shown in Figure 6 , comprising the following steps:

[0113] Step S61: the user starts the washing and drying integrated program.

[0114] Step S62: the washing program is executed until the washing is completed.

[0115] Step S63: the drying program is started, and the monitoring process is started to monitor the power and the load current of the variable frequency fan motor.

[0116] Step S64: from the start of the drying program, when the power drops by more than a first set range, and the fluctuation amplitude of the load current exceeds a set fluctuation range, it is judged that the drying program is in the initial drying stage.

[0117] Step S65: from the initial drying stage, when the power is maintained within a stable range, and the fluctuation amplitude of the load current exceeds the set fluctuation range, it is judged that the drying program is in the middle drying stage.

[0118] Step S66: from the middle drying stage, when the power drops by more than a second set value, and the fluctuation amplitude of the load current is within the set fluctuation range, it is judged that the drying program is in the final drying stage.

[0119] Step S67: the material information of the drying clothes is obtained.

[0120] In this embodiment, the material information of the drying clothes is set and stored in the step S61 when the user sets the washing parameters and the drying parameters, and is read in this step, or is determined and stored based on recognition technology before the washing program is started.

[0121] Step S68: the third running time of the final drying stage is determined based on the material of the clothes.
