[0027] Embodiment 1

[0028] Figure 1 This is a schematic diagram of the first process of the filter cleaning reminder method provided in an embodiment of the present application. The method can be executed by a filter cleaning reminder device or a clothes dryer. The device or clothes dryer can be implemented by software and / or hardware. The device or clothes dryer can be integrated into any smart device with network communication function. Figure 1 As shown, the filter cleaning prompt method may include the following steps:

[0029] S101. Detecting the wind speed of the air discharged from the dryer through the filter at the first position and the second position respectively by means of a first micro air volume meter and a second micro air volume meter; wherein the heights of the first position and the second position are the same as the height of the filter; the distance between the first position and the filter and the distance between the second position and the filter are both within a predetermined range; and the distance between the first position and the filter is smaller than the distance between the second position and the filter.

[0030] The structure of a clothes dryer mainly includes the following parts: 1) Outer shell: usually made of metal or plastic, used to protect the internal mechanical parts and electronic components. 2) Tray: a flat area for placing clothes, usually made of steel or plastic. 3) Mechanical parts: including motors, fans, mechanical transmission systems, etc. The motor is used to drive the operation of the internal mechanical parts, and the fan is responsible for sending air to the inside of the dryer. 4) Circuit board: used to control the operation of the electrical components inside the dryer, for example, controlling the speed of the fan, controlling the temperature of the heater, etc. 5) Heater: used to heat the air and send the warm air to the inside of the dryer, thereby accelerating the drying of clothes. 6) Drainage system: used to drain the water that may accumulate inside the dryer, usually including a drain pipe and a water pump. 7) Control panel: used to set and control the operation mode and time of the dryer, including switches, temperature and time controllers, etc.

[0031] The function of the dryer filter is to filter dust, fibers and other impurities in the air to prevent them from entering the dryer. The filter can prevent impurities from clogging the dryer's exhaust duct and keep the dryer working properly. At the same time, the filter can also prevent impurities from damaging clothing and other items during the drying process, making the clothes cleaner and neater. Therefore, it is crucial to clean and replace the dryer filter regularly to ensure the efficient operation of the dryer and protect the clothes.

[0032] The dryer filter is usually located in one of the following locations: 1) Door frame area: Some dryers have filters located above or below the door frame. Usually, the user needs to open the dryer door and check if there is a removable filter above or below the door frame, which may have a handle or button. 2) Control panel area: Some dryers may have filters located at the bottom or side of the control panel. The user can check the control panel area of ​​the dryer to see if there is a removable cover or hole, usually with a filter underneath. 3) Interior area: Some dryers have filters located inside the machine. The user needs to open the dryer body and may need to undo some screws or clips to gain internal access. The filter may be located at the bottom or side of the body.

[0033] In this step, the wind speed of the air discharged from the dryer through the filter at the first position and the second position is detected by the first micro air volume meter and the second micro air volume meter respectively; wherein the height of the first position and the second position is the same as the height of the filter; the distance between the first position and the filter and the distance between the second position and the filter are both within a predetermined range; and the distance between the first position and the filter is less than the distance between the second position and the filter. A micro air volume meter is a device for measuring air flow, which is suitable for narrow spaces or occasions requiring high-precision measurement. It is usually composed of a sensor, a display screen and a control panel, and can directly measure the air flow. There are many working principles of a micro air volume meter, the most common of which is to measure the air speed and flow through a hot film sensor. The hot film sensor will produce temperature changes when heated. When the air flows through the sensor, the temperature of the sensor will change. By measuring the temperature change, the air flow can be obtained. The micro air volume meter has the characteristics of small size, light weight, high precision, and fast response. When selecting a micro air volume meter, factors such as measurement range, accuracy requirements, response time, and sensor type need to be considered.

[0034] Figure 2 A schematic diagram of the positional relationship between the filter screen and the first micro air flow meter and the second micro air flow meter provided in the embodiment of the present application. Figure 2 As shown, the height of the first position and the second position is the same as the height of the filter; the distance between the first micro air volume meter and the filter is the first distance; the distance between the second micro air volume meter and the filter is the second distance; the first distance and the second distance are both within the predetermined range, and the first distance is smaller than the second distance.

[0035] S102: Determine the ventilation state of the filter according to the wind speeds of the air exhausted from the clothes dryer through the filter at the first position and the second position.

[0036] In this step, the clothes dryer can determine the ventilation state of the filter according to the wind speed of the wind discharged by the clothes dryer through the filter at the first position and the second position; wherein the ventilation state includes: normal operation state, primary blockage state and advanced blockage state. Specifically, if the wind speed of the wind discharged by the clothes dryer through the filter at the first position is greater than the preset wind speed threshold, and the wind speed of the wind discharged by the clothes dryer through the filter at the second position is greater than the wind speed threshold, the clothes dryer can determine that the ventilation state of the filter is a normal operation state. If the wind speed of the wind discharged by the clothes dryer through the filter at the first position is greater than the preset wind speed threshold, and the wind speed of the wind discharged by the clothes dryer through the filter at the second position is less than the wind speed threshold, the clothes dryer can determine that the ventilation state of the filter is a primary blockage state. If the wind speed of the wind discharged by the clothes dryer through the filter at the first position is less than the preset wind speed threshold, and the wind speed of the wind discharged by the clothes dryer through the filter at the second position is less than the wind speed threshold, the clothes dryer can determine that the ventilation state of the filter is an advanced blockage state.

[0037] S103, providing a cleaning reminder to the user according to the ventilation status of the filter.

[0038] In this step, the clothes dryer can give a cleaning prompt to the user according to the ventilation state of the filter. Specifically, if the ventilation state of the filter is a primary blockage state or a high-level blockage state, the clothes dryer can use the cleaning prompt method corresponding to the primary blockage state or the cleaning prompt method corresponding to the high-level blockage state to prompt the user to clean the filter. Further, if the ventilation state of the filter is a primary blockage state, a prompt message is displayed on the display screen of the clothes dryer, and the user is prompted to clean the filter through the prompt message; or, the prompt light of the clothes dryer is turned on, and the user is prompted to clean the filter through the prompt light. If the ventilation state of the filter is a high-level blockage state, the switch state of the clothes dryer is monitored; wherein the switch state of the clothes dryer includes: triggered on, running, and triggered off; when the switch state of the clothes dryer is triggered on, the filter is ejected from the initial position to the target position, and the user is forced to be prompted to clean the filter.

[0039] Specifically, the filter cleaning method may include the following steps: 1) opening the filter cover of the dryer.

[0040] 2) Take out the filter, rinse it with water, and use a soft brush to gently brush away the dust and debris on the filter. 3) Be careful not to pull or fold the filter forcefully to avoid deformation or damage. 4) After drying, install it back into the dryer and cover the filter cover. In addition, some dryers have a curved crescent-shaped structure inside the filter, which also needs to be cleaned regularly. You can use a soft brush to gently brush away the dust and debris inside, and then rinse it with water.

[0041] The filter cleaning prompt method proposed in the embodiment of the present application first detects the wind speed of the air discharged from the dryer through the filter at the first position and the second position respectively through the first micro air volume meter and the second micro air volume meter; then determines the ventilation state of the filter according to the wind speed of the air discharged from the dryer through the filter at the first position and the second position; and then prompts the user to clean the filter according to the ventilation state of the filter. That is to say, in the technical solution of the present application, the wind speed of the air discharged from the dryer through the filter at the first position and the second position can be detected by the first micro air volume meter and the second micro air volume meter respectively, and it is determined whether it is necessary to prompt the user to clean the filter based on the wind speed of the air discharged from the dryer through the filter at the first position and the second position detected by the first micro air volume meter and the second micro air volume meter. However, the existing methods cannot prompt the user very timely, so the user may not be able to clean the filter in time during the use of the dryer. Therefore, compared with the prior art, the filter cleaning reminder method proposed in the embodiment of the present application can prompt the user very timely, so the user can clean the filter in time during the use of the dryer; and the technical solution of the embodiment of the present application is simple and convenient to implement, easy to popularize, and has a wider range of applications.

[0042] Embodiment 2

[0043] Figure 3 The second flow chart of the filter cleaning prompt method provided in the embodiment of the present application is further optimized and expanded based on the above technical solution, and can be combined with the above optional implementation methods. Figure 3 As shown, the filter cleaning prompt method may include the following steps:

[0044] S301, using a first micro air volume meter and a second micro air volume meter to respectively detect the wind speed of the air discharged from the dryer through the filter at a first position and a second position; wherein the heights of the first position and the second position are the same as the height of the filter; the distance between the first position and the filter and the distance between the second position and the filter are both within a predetermined range; and the distance between the first position and the filter is smaller than the distance between the second position and the filter.

[0045] S302: If the wind speed of the air discharged through the filter by several clothes dryers at a first position is greater than a preset wind speed threshold, and the wind speed of the air discharged through the filter by the dryer at a second position is less than the wind speed threshold, it is determined that the ventilation state of the filter is a primary blockage state.

[0046] In this step, if the wind speed of the wind discharged through the filter by several clothes dryers at the first position is greater than the preset wind speed threshold, and the wind speed of the wind discharged through the filter by the dryer at the second position is less than the wind speed threshold, then the dryer can determine that the ventilation state of the filter is a primary blockage state. The primary blockage state of the filter in the embodiment of the present application refers to the beginning of the appearance of some impurities, dirt, particulate matter, etc. on the filter, which will partially or locally block the tiny pores of the filter or reduce the channel size of the filter, thereby affecting the normal operation and filtering effect of the filter. The primary blockage state generally refers to a relatively light degree of blockage, which has not completely closed the pores of the filter, but has reduced the filtering efficiency of the filter. In the primary blockage state, the filter can still work normally, but needs to be cleaned or replaced regularly to maintain a normal filtering effect.

[0047] S303: If the ventilation state of the filter is the primary blocking state, a prompt message is displayed on the display screen of the clothes dryer to prompt the user to clean the filter; or, a prompt light of the clothes dryer is turned on to prompt the user to clean the filter.

[0048] The filter cleaning prompt method proposed in the embodiment of the present application first detects the wind speed of the air discharged from the dryer through the filter at the first position and the second position respectively through the first micro air volume meter and the second micro air volume meter; then determines the ventilation state of the filter according to the wind speed of the air discharged from the dryer through the filter at the first position and the second position; and then prompts the user to clean the filter according to the ventilation state of the filter. That is to say, in the technical solution of the present application, the wind speed of the air discharged from the dryer through the filter at the first position and the second position can be detected by the first micro air volume meter and the second micro air volume meter respectively, and it is determined whether it is necessary to prompt the user to clean the filter based on the wind speed of the air discharged from the dryer through the filter at the first position and the second position detected by the first micro air volume meter and the second micro air volume meter. However, the existing methods cannot prompt the user very timely, so the user may not be able to clean the filter in time during the use of the dryer. Therefore, compared with the prior art, the filter cleaning reminder method proposed in the embodiment of the present application can prompt the user very timely, so the user can clean the filter in time during the use of the dryer; and the technical solution of the embodiment of the present application is simple and convenient to implement, easy to popularize, and has a wider range of applications.

[0049] Embodiment 3

[0050] Figure 4 The third flow chart of the filter cleaning prompt method provided in the embodiment of the present application is further optimized and expanded based on the above technical solution, and can be combined with the above optional implementation methods.

[0051] like Figure 4 As shown, the filter cleaning prompt method may include the following steps:

[0052] S401, respectively detecting the wind speed of the air discharged from the dryer through the filter at the first position and the second position by using a first micro air volume meter and a second micro air volume meter; wherein the heights of the first position and the second position are the same as the height of the filter; the distance between the first position and the filter and the distance between the second position and the filter are both within a predetermined range; and the distance between the first position and the filter is smaller than the distance between the second position and the filter.

[0053] S402: If the wind speed of the air discharged through the filter by several clothes dryers at a first position is less than a preset wind speed threshold, and the wind speed of the air discharged through the filter by the dryer at a second position is less than the wind speed threshold, it is determined that the ventilation state of the filter is a high-level blockage state.

[0054] In this step, if the wind speed of the air discharged through the filter screen of several clothes dryers at the first position is less than the preset wind speed threshold, and the wind speed of the air discharged through the filter screen of the dryer at the second position is less than the wind speed threshold, the dryer can determine that the ventilation state of the filter screen is a high-level blockage state. The high-level blockage state of the filter screen in the embodiment of the present application refers to the state in which the pores of the filter screen are completely or almost completely blocked due to the continuous accumulation of pollutants during the operation of the filter screen. In this state, the filter screen cannot effectively filter pollutants, which will cause the filtering effect to decrease or even fail completely.

[0055] S403: If the ventilation state of the filter is a high-level clogging state, monitor the on / off state of the clothes dryer; wherein the on / off state of the clothes dryer includes: triggered on, running, and triggered off.

[0056] In a specific embodiment of the present application, the dryer is usually triggered to turn on in the following ways: 1) Manual method: There is usually a manual switch on the dryer, and the user only needs to manually turn the switch to the on position. 2) Button control: The dryer is usually equipped with an electronic panel or button, and the dryer is started and stopped by pressing the corresponding button. 3) Timer control: There may be a timer on the dryer, and the user can set a predetermined drying time. When the time is reached, the dryer will start automatically. 4) Sensor trigger: The dryer is usually equipped with some sensors to detect humidity or the weight of the clothes. Once it is detected that the humidity or weight of the clothes exceeds the set threshold, the dryer will start automatically.

[0057] S404: When the switch state of the clothes dryer is triggered to be on, the filter is ejected from the initial position to the target position, forcing the user to clean the filter.

[0058] In a specific embodiment of the present application, before the wind speed of the air discharged from the dryer through the filter at the first position and the second position is detected by the first micro air flow meter and the second micro air flow meter respectively, the wind speed of the air discharged from the dryer without passing through the filter at the first position and the second position can also be detected by the first micro air flow meter and the second micro air flow meter respectively, and the equipment parameters of the dryer and the parameters of the actual clothes in the dryer are obtained; wherein the equipment parameters of the dryer at least include: the motor speed of the dryer, the area of ​​the filter, and the volume of the space in the barrel of the dryer; the parameters of the actual clothes in the dryer at least include: the volume of the space occupied by the actual clothes in the dryer; and then the wind speed threshold is determined according to the wind speed of the air discharged from the dryer without passing through the filter at the first position and the second position, the equipment parameters of the dryer, and the parameters of the actual clothes in the dryer. Specifically, the dryer can input the wind speed of the air discharged from the dryer without passing through the filter at the first position and the second position, the equipment parameters of the dryer, and the parameters of the actual clothes in the dryer into a pre-constructed calculation model, and output the wind speed threshold through the calculation model.

[0059] Specifically, the dryer equipment parameters in the embodiment of the present application may include the capacity, power, speed, etc. of the fan; these parameters determine the limit of the wind speed generated by the dryer. The parameters of the actual clothes in the dryer may include the number, weight, thickness, material, etc. of clothes; these parameters affect the speed of moisture absorption of clothes and the efficiency of heat transfer. The wind speed of the wind discharged from the dryer without passing through the filter at the first position can be obtained by the first micro air flow meter; the wind speed of the wind discharged from the dryer without passing through the filter at the second position can be obtained by the second micro air flow meter. According to the above parameters, a series of experiments and measurements can be carried out to analyze the influence of different dryer equipment parameters and actual clothing parameters on the wind speed. Through statistical analysis and data processing, a suitable wind speed threshold can be calculated. It should be noted that the wind speed threshold may vary due to different types and sizes of clothes. Therefore, in actual use, different wind speed thresholds can be set for different types of clothes. In addition, the design and performance of the dryer will also affect the drying effect of the clothes. Therefore, when determining the wind speed threshold, the overall performance and design characteristics of the dryer need to be considered.

[0060] Specifically, the following methods can be used to obtain the motor speed of the dryer in the embodiment of the present application: 1) Manufacturer's manual: Refer to the manufacturer's manual of the dryer, which usually provides relevant information about the motor speed. 2) Measuring voltage frequency: The motor speed of the dryer is usually related to the voltage frequency. A multimeter can be used to measure the voltage and frequency on the power socket of the dryer; then, the measured power frequency is converted into the motor speed. 3) Use a speed measuring instrument: Use a special speed measurement tool, such as a laser velocimeter or a Hall effect sensor, and aim the instrument at the rotating part of the motor to accurately measure the motor speed. It should be noted that the motor speed of the dryer is usually measured in revolutions per minute.

[0061] Specifically, the area of ​​the filter screen can be obtained by the following method in the embodiment of the present application: 1) First, it is necessary to determine the shape of the dryer filter screen. Generally speaking, the dryer filter screen is rectangular or square in shape, but some filters are circular or other irregular shapes. 2) If the filter screen is rectangular or square in shape, its length and width can be measured directly. Use a ruler or other measuring tool to measure the longest side of the filter screen as the length, and measure the adjacent sides as the width. 3) Based on the measured length and width, calculate the area of ​​the filter screen. Use the following formula to calculate the area of ​​a rectangular or square filter screen: Area = Length × Width. 4) If the filter screen is circular in shape, measure its diameter or radius. 5) Based on the measured diameter or radius, use the circle area formula to calculate the area of ​​the circular filter screen.

[0062] Specifically, the following methods can be used to obtain the volume of the space inside the barrel of the dryer in the embodiment of the present application: 1) Determine the shape of the dryer barrel: The dryer barrel is usually cylindrical or rectangular, and the shape of the barrel needs to be determined in order to calculate the volume. 2) Calculate the volume of a cylindrical barrel: If the dryer barrel is cylindrical, the following formula can be used to calculate the volume: Volume = π × radius 2 × height, where π is pi, the radius is the radius of the bottom of the barrel, and the height is the height of the barrel. 3) Calculate the volume of a rectangular barrel: If the dryer barrel is rectangular, the following formula can be used to calculate the volume: Volume = length × width × height, where the length is the length of the barrel, the width is the width of the barrel, and the height is the height of the barrel.

[0063] Specifically, the following method can be used to obtain the actual volume of the space occupied by the clothes in the dryer in the embodiment of the present application: 1) Empty the dryer completely to ensure that there are no clothes or other items inside. 2) Measure the size of the inside of the dryer. Use a ruler or tape measure to measure the length, width and height inside the dryer. 3) Calculate the volume inside the dryer. Multiply the measured length, width and height to calculate the volume inside the dryer. The formula is: volume = length × width × height. 4) Put in a certain amount of clothes. According to the capacity indication of the dryer or the suggestions in the user manual, put a certain amount of clothes into the dryer. 5) Close the dryer door and start it, ensuring that the clothes are fully unfolded and not compressed or stacked against each other. 6) Take out the clothes and compare the volume before and after. Take the clothes out of the dryer and remeasure, and calculate the difference in volume inside the dryer before and after taking out the clothes. This difference is the volume of the space actually occupied by the clothes. It should be noted that due to different factors such as the tightness and stacking method of the clothes, there may be some errors in each measurement. Therefore, to obtain more accurate results, multiple measurements can be taken and the average value calculated.

[0064] The filter cleaning prompt method proposed in the embodiment of the present application first detects the wind speed of the air discharged from the dryer through the filter at the first position and the second position respectively through the first micro air volume meter and the second micro air volume meter; then determines the ventilation state of the filter according to the wind speed of the air discharged from the dryer through the filter at the first position and the second position; and then prompts the user to clean the filter according to the ventilation state of the filter. That is to say, in the technical solution of the present application, the wind speed of the air discharged from the dryer through the filter at the first position and the second position can be detected by the first micro air volume meter and the second micro air volume meter respectively, and it is determined whether it is necessary to prompt the user to clean the filter based on the wind speed of the air discharged from the dryer through the filter at the first position and the second position detected by the first micro air volume meter and the second micro air volume meter. However, the existing methods cannot prompt the user very timely, so the user may not be able to clean the filter in time during the use of the dryer. Therefore, compared with the prior art, the filter cleaning reminder method proposed in the embodiment of the present application can prompt the user very timely, so the user can clean the filter in time during the use of the dryer; and the technical solution of the embodiment of the present application is simple and convenient to implement, easy to popularize, and has a wider range of applications.
