Description

Technical Field

[0001] This application relates to the field of clothes dryer technology, and more particularly to a clothes dryer and its control method. Background Technology

[0002] A clothes dryer dries clothes by circulating hot air inside the drum. For example, a heating device and a fan can be installed inside the dryer. The fan drives the heated airflow into the drying drum to dry the clothes.

[0003] The drying efficiency of a clothes dryer is related to the user experience and energy consumption, and how to improve drying efficiency is a technical problem that urgently needs to be solved. Summary of the Invention

[0004] This application provides a clothes dryer and its control method for improving the drying efficiency of the clothes dryer.

[0005] In a first aspect, a clothes dryer is provided, comprising: Box; The clothes dryer, located inside the cabinet, is used to hold clothes that need to be dried; The fan's outlet is connected to the dryer's inlet; The evaporator, located in the return air duct of the clothes dryer, is used to liquefy the moisture in the flowing gas in the return air duct to condense water. The controller, electrically connected to the wind turbine, is configured as follows: During the operation of the drying program, the changes in drying influencing parameters and the changes in condensate precipitation are obtained for at least the two most recent consecutive drying stages. The drying influencing parameters include at least the fan speed. Adjust the drying impact parameters for the next drying stage based on changes in the drying impact parameters and the amount of condensate produced.

[0006] The technical solution provided in this application provides at least the following beneficial effects: By acquiring the changes in drying influencing parameters and condensate precipitation during at least two consecutive drying stages, it is possible to understand how condensate precipitation changes with the drying influencing parameters. Based on this, the drying influencing parameters for the next stage can be adjusted, thereby maintaining the drying efficiency of the dryer provided in this application at a high level, shortening the drying time, saving time for users, and improving the user experience. Furthermore, when only the fan speed is considered as the drying influencing parameter, there is no need to adjust the drying temperature of the dryer, thus improving the drying efficiency of the dryer without increasing its power consumption, and further saving energy.

[0007] In some embodiments, the dryer further includes: a drip tray disposed below the evaporator for collecting condensate; a water level detector disposed on the drip tray; and a controller of the dryer electrically connected to the water level detector. The controller is configured to acquire changes in the amount of condensate extracted during at least two recent consecutive drying stages, specifically by acquiring the amounts of condensate extracted during the (i-1)th and ith drying stages respectively via the water level detector at the end of the (i-1)th and ith drying stages; and determining the change in the amount of condensate extracted based on these amounts. This allows for accurate acquisition of the amounts of condensate extracted during the (i-1)th and ith drying stages, thus revealing the change in the amount of condensate extracted, facilitating the determination of the correlation between the amount of condensate extracted and drying-related parameters in subsequent processes.

[0008] In some embodiments, the controller of the dryer adjusts the drying influence parameters for the next drying stage based on changes in drying influence parameters and changes in condensate precipitation. Specifically, it is configured as follows: if the fan speed in stage i is greater than the fan speed in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, the fan speed in stage i+1 is determined to be the sum of the fan speed in stage i and a first preset speed; if the fan speed in stage i is greater than the fan speed in stage i-1, and the condensate precipitation rate in stage i is less than the condensate precipitation rate in stage i-1, the fan speed in stage i+1 is determined to be the difference between the fan speed in stage i-1 and a second preset speed; wherein the condensate precipitation rate in stage i is determined based on the condensate precipitation amount and the duration of stage i, and the condensate precipitation rate in stage i-1 is determined based on the condensate precipitation amount and the duration of stage i-1. In this way, if the fan speed in stage i is greater than that in stage i-1, the controller can determine the impact of the increased fan speed on the condensate precipitation rate based on the changes in the condensate precipitation rate in stages i and i-1. This allows the controller to adjust the fan speed in the next stage to keep the condensate precipitation rate as high as possible, thereby improving drying efficiency.

[0009] In some embodiments, the controller of the dryer adjusts the drying influence parameters for the next drying stage based on changes in drying influence parameters and changes in condensate precipitation. Specifically, it is configured as follows: if the fan speed in stage i is less than the fan speed in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, the fan speed in stage i+1 is determined to be the difference between the fan speed in stage i and a third preset speed; if the fan speed in stage i is less than the fan speed in stage i-1, and the condensate precipitation rate in stage i is less than the condensate precipitation rate in stage i-1, the fan speed in stage i+1 is determined to be the sum of the fan speed in stage i-1 and a fourth preset speed. In this way, if the fan speed in stage i is less than that in stage i-1, the controller can determine the impact of the reduced fan speed on the condensate precipitation rate based on the changes in the condensate precipitation rate in stages i and i-1. This allows the controller to adjust the fan speed in the next stage to keep the condensate precipitation rate as high as possible, thereby improving the drying efficiency.

[0010] In some embodiments, the dryer further includes a heating device; the drying influence parameters also include the heating power of the heating device; the controller of the dryer adjusts the drying influence parameters for the next drying stage based on changes in the drying influence parameters and changes in the amount of condensate, specifically configured as follows: if the fan speed in stage i is greater than the fan speed in stage i-1, the heating power in stage i is greater than the heating power in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, the fan speed in stage i+1 is determined to be the sum of the fan speed in stage i and a fifth preset speed, and the heating power in stage i+1 is the sum of the heating power in stage i and the fifth preset speed. The sum of the first preset power; if the fan speed in stage i is greater than the fan speed in stage i-1, the heating power in stage i is greater than the heating power in stage i-1, and the condensate precipitation rate in stage i is less than the condensate precipitation rate in stage i-1, the fan speed in stage i+1 is determined to be the difference between the fan speed in stage i-1 and the sixth preset speed, and the heating power in stage i+1 is the difference between the heating power in stage i-1 and the second preset power; wherein, the condensate precipitation rate in stage i is determined based on the condensate precipitation amount in stage i and the duration of stage i, and the condensate precipitation rate in stage i-1 is determined based on the condensate precipitation amount in stage i-1 and the duration of stage i-1. Thus, if the fan speed in stage i is greater than that in stage i-1, and the heating power in stage i is greater than that in stage i-1, the controller can determine the impact of simultaneously increasing the fan speed and heating power on the condensate precipitation rate based on the changes in the condensate precipitation rate in stages i and i-1. This allows the controller to adjust the fan speed and heating power in the next stage to maintain the condensate precipitation rate at a relatively high level, thereby improving drying efficiency.

[0011] In some embodiments, the controller of the dryer adjusts the drying influencing parameters for the next drying stage based on changes in drying influencing parameters and changes in condensate precipitation. Specifically, it is configured to: if the fan speed in stage i is greater than the fan speed in stage i-1, the heating power in stage i is less than the heating power in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, then the fan speed in stage i+1 is determined to be the fan speed in stage i plus a seventh preset speed. The sum of the heating power in stage i+1 is the difference between the heating power in stage i and the third preset power. If the fan speed in stage i is greater than that in stage i-1, the heating power in stage i is less than that in stage i-1, and the condensate precipitation rate in stage i is less than that in stage i-1, then the fan speed in stage i+1 is determined to be the difference between the fan speed in stage i-1 and the eighth preset speed, and the heating power in stage i+1 is the sum of the heating power in stage i-1 and the fourth preset power. Thus, if the fan speed in stage i is greater than that in stage i-1, and the heating power in stage i is less than that in stage i-1, the controller can determine the impact of the decrease in heating power while the fan speed increases on the condensate precipitation rate based on the changes in the condensate precipitation rates in stages i and i-1. This allows the controller to adjust the fan speed and heating power in the next stage to maintain the condensate precipitation rate at a relatively high level, thereby improving drying efficiency.

[0012] In some embodiments, the controller of the dryer adjusts the drying influence parameters for the next drying stage based on changes in drying influence parameters and changes in condensate precipitation. Specifically, it is configured to: if the fan speed in stage i is less than the fan speed in stage i-1, the heating power in stage i is less than the heating power in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, determine the fan speed in stage i+1 as the fan speed in stage i plus a ninth preset speed. The difference between the heating power of stage i+1 and the heating power of stage i is the difference between the heating power of stage i and the fifth preset power. If the fan speed of stage i is less than the fan speed of stage i-1, the heating power of stage i is less than the heating power of stage i-1, and the condensate precipitation rate of stage i is less than the condensate precipitation rate of stage i-1, then the fan speed of stage i+1 is determined to be the sum of the fan speed of stage i-1 and the tenth preset speed, and the heating power of stage i+1 is the sum of the heating power of stage i-1 and the sixth preset power. Thus, if the fan speed of stage i is less than the fan speed of stage i-1, and the heating power of stage i is less than the heating power of stage i-1, the controller can determine the impact of the simultaneous decrease in fan speed and heating power on the condensate precipitation rate based on the changes in the condensate precipitation rates of stages i and i-1. This allows the controller to adjust the fan speed and heating power of the next stage to maintain the condensate precipitation rate at a relatively high level, thereby improving drying efficiency.

[0013] In some embodiments, the controller of the dryer adjusts the drying influencing parameters for the next drying stage based on changes in drying influencing parameters and changes in condensate precipitation. Specifically, it is configured to: if the fan speed in stage i is less than the fan speed in stage i-1, the heating power in stage i is greater than the heating power in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, then the fan speed in stage i+1 is determined to be the fan speed in stage i plus an eleventh preset speed. The difference between the heating power and the condensate extraction rate is determined by the following: the heating power of stage i+1 is the sum of the heating power of stage i and the seventh preset power. If the fan speed of stage i is less than that of stage i-1, the heating power of stage i is greater than that of stage i-1, and the condensate extraction rate of stage i is less than that of stage i-1, then the fan speed of stage i+1 is determined to be the sum of the fan speed of stage i-1 and the twelfth preset speed, and the heating power of stage i+1 is the difference between the heating power of stage i-1 and the eighth preset power. Thus, if the fan speed of stage i is less than that of stage i-1, and the heating power of stage i is greater than that of stage i-1, the controller can determine the impact of decreasing fan speed and increasing heating power on the condensate extraction rate based on the changes in the condensate extraction rates of stages i and i-1. This allows the controller to adjust the fan speed and heating power of the next stage to maintain the condensate extraction rate at a relatively high level, thereby improving drying efficiency.

[0026] Clothes dryers use circulating hot air to dry clothes inside the drum. For example, a heating element and a fan can be installed inside the dryer. The fan drives heated airflow into the drum to dry the clothes. The drying efficiency of a clothes dryer directly affects the user experience and energy consumption; therefore, improving drying efficiency is a pressing technical problem that needs to be solved.

[0027] In view of this, this application provides a clothes dryer whose controller acquires the changes in drying influencing parameters and condensate precipitation during two consecutive drying stages. This allows the controller to determine how condensate precipitation changes with the drying influencing parameters and adjust the parameters for the next stage to better suit the drying conditions. Consequently, the dryer maintains high drying efficiency, shortens drying time, saves user time, and improves the user experience.

[0028] Figure 1 This is a schematic diagram of the mechanical structure of a clothes dryer provided in an embodiment of this application. Figure 1 As shown, the dryer 10 may include: a housing 101, a door 102, a drying drum 103, an evaporator 104, a condenser 105, a fan 106, a drip tray 107, a water level detector 108, a water valve 109, a motor 110, a motor shaft 111, a water storage tank 112, and a controller 113 (not shown). The evaporator 104, condenser 105, fan 106, water level detector 108, water valve 109, and motor 110 are all connected to the controller 113.

[0029] In some embodiments, the housing 101 is used to protect the electrical components inside the dryer 10, and to seal the channels between the inside and outside of the dryer 10 to prevent damage to the electrical components.

[0030] In some embodiments, the door 102 is disposed on the housing 101, and the clothes inside the clothes dryer 103 can be put in and taken out by opening and closing the door 102.

[0031] In some embodiments, the clothes dryer 103 is located inside the housing 101 and is used to hold clothes to be dried. There is an air duct between the clothes dryer 103 and the housing 101. The clothes dryer 103 has an air inlet and an air outlet. The two ends of the air duct are respectively connected to the air inlet and the air outlet of the clothes dryer 103.

[0032] In some embodiments, an evaporator 104 and a condenser 105 are sequentially arranged on the return air duct of the clothes dryer 103, according to the flow direction of the gas inside the clothes dryer 103. The evaporator 104 is used to liquefy the moisture in the flowing gas in the return air duct to condense water; the condenser 105 is used to heat the gas in the return air duct to evaporate the moisture from the clothes inside the clothes dryer 103.

[0033] In some embodiments, the fan 106 is used to increase the air pressure in the duct and discharge high-pressure air. It is a machine that relies on input mechanical energy to increase gas pressure and discharge gas. It can also be a ventilator, blower, variable frequency fan, etc. The fan 106 can be set at the air inlet of the dryer drum 103, so that the hot air generated by the heat generated by the condenser 105 is blown into the dryer drum 103, and the air can circulate in a directional manner in the duct.

[0034] When the dryer 10 is working, the surface of the condenser 105 is high-temperature, while the surface of the evaporator 104 is low-temperature. The compressor performs work on the refrigerant, converting electrical energy into heat energy, which is then transferred to the air inside the drying drum 103 through heat exchange. Figure 2 As shown, the fan 106 drives the air to circulate in a directional manner within the air duct. After being heated by the condenser 105, the air is blown into the drying drum 103. The hot air comes into contact with the damp clothes in the drying drum 103 and becomes humid and hot air. The humid and hot air flows through the air duct to the evaporator 104. Through heat exchange, the humid and hot air is cooled and liquefied at the evaporator 104, and condensation occurs. The air in the air duct is continuously heated and condensed repeatedly until the dryer 10 ends the current drying cycle.

[0035] In some embodiments, a drip tray 107 is disposed below the evaporator 104 to collect condensate.

[0036] In some embodiments, a water level detector 108 is disposed at the water receiving pan 107 to detect the amount of condensate precipitated in the water receiving pan. The water level detector 108 can be a pressure sensor, gravity sensor, water level sensor, etc., and this embodiment does not limit its application to this type. For example, Figure 1 Taking the water level detector 108 as an example, with the pressure sensor 1081, the pressure sensor 1081 obtains the pressure value of the condensate at the bottom of the water receiving pan 107 through the pressure tube 1082, and then determines the amount of condensate precipitation based on the pressure value. Alternatively, the controller 113 obtains the water level of the condensate in the water receiving pan 107 through a water level sensor, and then determines the amount of condensate precipitation.

[0037] In some embodiments, a water valve 109 is disposed below a water receiving pan 107 to control the outflow of condensate from the water receiving pan 107.

[0038] In some embodiments, the motor 110 is used to provide driving power for the dryer 10. For example... Figure 1 As shown, when the dryer 10 is drying clothes, the motor 110 can drive the fan 106 to rotate through the motor shaft 111.

[0039] In some embodiments, the water storage tank 112 is disposed in the bottom air duct for storing condensate that is released during the drying process.

[0040] In some embodiments, controller 113 refers to a device that can generate operation control signals based on instruction opcodes and timing signals to instruct the dryer 10 to execute control instructions. Exemplarily, controller 113 can be a central processing unit (CPU), a network processor (NP), a digital signal processor (DSP), a programmable logic device (PLD), a microprocessor, a microcontroller, or any combination thereof. Controller 113 can also be other devices with processing functions, such as circuits, devices, or software modules; this application embodiment does not impose any limitations on this.

[0041] For example, after the user selects and starts the drying program, the controller 113 can control the operation of various electrical components to dry the clothes in the drying drum 103 to meet the user's needs.

[0042] Figure 3 An exemplary circuit system architecture diagram of dryer 10 is shown. (As follows) Figure 3 As shown, the dryer 10 may further include: a heating device 114, a temperature sensor 115, a humidity sensor 116, a display 117, a voice prompt device 118, a human-machine interaction device 119, a communication device 120, and a power supply 121. The heating device 114, temperature sensor 115, humidity sensor 116, display 117, voice prompt device 118, human-machine interaction device 119, communication device 120, and power supply 121 are all connected to the controller 113.

[0043] In some embodiments, the heating device 114 is used to heat the air inside the dryer drum 103. The heating device 114 may be a heating assembly having a heating tube or a heating element.

[0044] Optionally, the heating device 114 may exist independently of the condenser 105 or may be integrated with the condenser 105; this application embodiment does not impose any restrictions on this.

[0045] In some embodiments, temperature sensor 115 refers to a sensor capable of detecting temperature and converting the detected temperature value into a usable output signal. For example, temperature sensor 115 can be used to detect the temperature of the air inside the dryer drum 103 and send the detected temperature value to controller 113, which then controls the various electrical components to perform corresponding operations based on the drying temperature detected by temperature sensor 115.

[0046] In some embodiments, the humidity sensor 116 refers to a sensor capable of detecting humidity and converting the detected humidity value into a usable output signal. For example, the humidity sensor 116 can be used to detect the humidity of the air inside the dryer drum 103 and send the detected humidity value to the controller 113. The controller 113 then adjusts the operating parameters of each electrical component based on the humidity detected by the humidity sensor 116. For instance, when the humidity value detected by the humidity sensor 116 meets the drying end condition, the controller 113 controls the dryer 10 to end the drying program.

[0047] In some embodiments, the display 117 may be a liquid crystal display or an organic light-emitting diode (OLED) display. The specific type, size, and resolution of the display are not limited, but those skilled in the art will understand that the display can be modified in terms of performance and configuration as needed.

[0048] In some embodiments, the display 117 may be used to display the control panel of the dryer 10 or the operating information of the dryer 10. For example, such as... Figure 4 As shown, the dryer 10 displays operating information such as the running time and the currently running drying program on the display 117.

[0049] In some embodiments, the voice prompt device 118 is used to play voice prompt information according to a program. The content of the voice prompt information can be preset by the dryer manufacturer 10, or it can be set by the user through the human-machine interface device 119. For example, when the controller 113 detects through the humidity sensor 116 that the humidity inside the drying drum 103 has met the drying end condition, the controller 113 can control the voice prompt device 116 to play a prompt message such as "Drying complete".

[0050] In some embodiments, the human-computer interaction device 119 is used to enable interaction between the user and the dryer 10. The human-computer interaction device 119 may include one or more of physical buttons or a touch display panel. For example, the user can use the human-computer interaction device 119 to set the drying program that the dryer 10 should run.

[0051] In some embodiments, the communication device 120 is a component for communicating with external devices or servers according to various communication protocol types. For example, the communication device 120 may include at least one of the following: a Wi-Fi module, a Bluetooth module, a wired Ethernet module, a near-field communication (NFC) module, and other network communication protocol chips or NFC protocol chips, as well as an infrared receiver. The communication device 120 can be used to communicate with other devices or communication networks (such as Ethernet, radio access network (RAN), wireless local area networks (WLAN), etc.).

[0052] In some embodiments, the controller 113 can communicate with the terminal device used by the user via the communication device 120. For example, such as Figure 5 As shown, the user's terminal device is a mobile phone. The controller 113 receives the drying program selected by the user on the mobile phone through the communication device 120, and then controls the electrical components of the dryer 10 to start executing the drying program.

[0053] In some embodiments, the power supply 121, under the control of the controller 113, provides power supply support for the dryer 10 by using the power input from the external power source.

[0054] The specific solution of this application will be described in detail below with reference to the accompanying drawings.

[0055] This application provides a method for controlling a water heater, such as... Figure 6 As shown, the method includes the following steps: S101. During the operation of the drying program, the controller acquires the changes in drying influencing parameters and the changes in condensate precipitation for at least the two most recent consecutive drying stages.

[0056] Among them, the drying parameters include at least the fan speed.

[0057] In some embodiments, the controller obtains the amount of condensate precipitated in the (i-1)th drying stage and the amount of condensate precipitated in the ith drying stage through a water level detector at the end of the (i-1)th drying stage and the ith drying stage, respectively, and then determines the change in the amount of condensate precipitated based on the amount of condensate precipitated in the (i-1)th drying stage and the ith drying stage.

[0058] For example, the water level detector is a water level sensor. The controller can obtain the water level of the condensate in the drip tray through the water level sensor, and then determine the amount of condensate to be released based on the pre-stored correspondence between the water level and the amount of condensate released. Assume that at the end of the (i-1)th drying stage, the controller determines the amount of condensate released as X1, and at the end of the ith drying stage, the controller determines the amount of condensate released as X2. If X2 > X1, it indicates that the amount of condensate released is gradually increasing; if X2 < X1, it indicates that the amount of condensate released is gradually decreasing; if X2 = X1, it indicates that the amount of condensate released in the two drying stages is the same.

[0059] Optionally, the drying stages can be divided based on duration or based on the degree of drying of the clothes. The drying stages can be preset by the dryer manufacturer or set by the user during use of the dryer; this embodiment does not limit this.

[0060] S102. The controller determines the drying influence parameters for the next drying stage based on the changes in drying influence parameters and the changes in condensate precipitation.

[0061] The drying function of a clothes dryer relies on the evaporation of moisture from the clothes inside the drying drum and the condensation of water at the evaporator. When the dryer's fan speed increases, the air circulation speed inside the drum also increases, leading to a faster rate of heat radiation from the circulating gas and a decrease in the temperature of the circulating gas. This means the relationship between the circulating gas temperature and the fan speed is a monotonically decreasing function. Therefore, the relationship between the evaporation efficiency of moisture in the clothes and the fan speed is unclear, as is the relationship between the condensation efficiency at the evaporator and the fan speed. In other words, the drying efficiency of the dryer is not clearly defined in relation to the fan speed. However, the more condensation that occurs within the same time frame while drying clothes, the faster the moisture on the clothes is removed at the evaporator, indicating a higher drying efficiency. The controller can determine the impact of changes in fan speed on the amount of condensation based on the changes in fan speed and condensation during the drying process, thus facilitating subsequent adjustments to the fan speed.

[0062] For example, if the fan speed in this drying stage is greater than the fan speed in the previous drying stage, and the amount of condensate produced in this drying stage is greater than the amount of condensate produced in the previous drying stage, it indicates that as the fan speed increases, the amount of condensate produced increases, that is, the drying efficiency increases. Therefore, in the next drying stage, the fan speed should continue to be increased so that the drying efficiency is maintained at a high level.

[0063] Figure 6The technical solution presented offers at least the following benefits: By acquiring the changes in drying influencing parameters and condensate precipitation during two consecutive drying stages, it is possible to understand how condensate precipitation changes with the drying influencing parameters. Based on this, the drying influencing parameters for the next stage can be adjusted. Therefore, the drying efficiency of the dryer provided in this application can be maintained at a high level, and the drying time can be shortened, saving time for users and improving the user experience. Furthermore, when only the fan speed is considered as the drying influencing parameter, there is no need to adjust the drying temperature of the dryer, thereby improving the drying efficiency without increasing the power consumption of the dryer and saving energy.

[0064] In some embodiments, based on Figure 6 ,like Figure 7 As shown, the specific implementation of step S102 may include step S201 or step S202.

[0065] S201. If the fan speed in stage i is greater than the fan speed in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, the controller determines the fan speed in stage i+1 to be the sum of the fan speed in stage i and the first preset speed.

[0066] The condensation rate in stage i is determined by the amount of condensation in stage i and the duration of stage i, and the condensation rate in stage (i-1) is determined by the amount of condensation in stage (i-1) and the duration of stage (i-1). For example, if the duration of the i-th drying stage is 3 minutes and the amount of condensation in the i-th drying stage is 0.6 L, then the condensation rate in stage i is 0.2 L / min.

[0067] The first preset speed is used to indicate the amount of adjustment of the fan speed by the controller. For example, if the first preset speed is 100 r / min and the fan speed in the i-th stage is 1500 r / min, and the controller determines that the fan speed in the (i+1)-th stage is the sum of the fan speed in the i-th stage and the first preset speed, then the fan speed in the (i+1)-th stage is 1600 r / min.

[0068] It should be understood that when the fan speed in the i-th stage is greater than that in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is greater than or equal to that in the (i-1)-th stage, it means that the drying efficiency is also increasing as the fan speed increases. Therefore, the fan speed is increased again in the next stage so that the drying efficiency of the dryer can be maintained at a high level.

[0069] S202. If the fan speed in stage i is greater than the fan speed in stage i-1, and the condensate precipitation rate in stage i is less than the condensate precipitation rate in stage i-1, the controller determines the fan speed in stage i+1 to be the difference between the fan speed in stage i-1 and the second preset speed.

[0070] It should be understood that when the fan speed in the i-th stage is greater than that in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is less than that in the (i-1)-th stage, it means that the drying efficiency is decreasing as the fan speed increases. Therefore, the fan speed should be reduced in the next stage to keep the drying efficiency of the dryer at a high level.

[0071] Figure 7 The technical solution shown brings at least the following beneficial effects: If the fan speed in the i-th stage is greater than the fan speed in the (i-1)-th stage, the influence of the increased fan speed on the condensate precipitation rate can be determined based on the changes in the condensate precipitation rate in the i-th and (i-1)-th stages. This allows for the adjustment of the fan speed in the next stage, ensuring that the condensate precipitation rate remains at a relatively high level, thereby improving drying efficiency.

[0072] In some embodiments, such as Figure 8 As shown, the specific implementation of step S102 may also include step S203 or step S204.

[0073] S203. If the fan speed in stage i is less than the fan speed in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, the controller determines the fan speed in stage i+1 to be the difference between the fan speed in stage i and the third preset speed.

[0074] It should be understood that when the fan speed in the i-th stage is less than that in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is greater than or equal to that in the (i-1)-th stage, it means that the drying efficiency is increasing as the fan speed decreases. Therefore, the fan speed should be increased in the next stage to maintain the drying efficiency of the dryer at a high level.

[0075] S204. If the fan speed in stage i is less than the fan speed in stage i-1, and the condensate precipitation rate in stage i is less than the condensate precipitation rate in stage i-1, the controller determines that the fan speed in stage i+1 is the sum of the fan speed in stage i-1 and the fourth preset speed.

[0076] It should be understood that when the fan speed in the i-th stage is less than that in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is less than that in the (i-1)-th stage, it means that the drying efficiency is decreasing as the fan speed decreases. Therefore, the fan speed should be increased in the next stage to keep the drying efficiency of the dryer at a high level.

[0077] Figure 8 The technical solution shown brings at least the following beneficial effects: If the fan speed in the i-th stage is less than the fan speed in the i-1-th stage, the effect of the reduced fan speed on the condensate precipitation rate can be determined based on the changes in the condensate precipitation rate in the i-th and i-1-th stages. This allows for the adjustment of the fan speed in the next stage, ensuring that the condensate precipitation rate remains at a relatively high level, thereby improving drying efficiency.

[0078] In some embodiments, the drying effect parameter also includes the heating power of the heating device. This is based on... Figure 6 ,like Figure 9 As shown, the specific implementation of step S102 may include step S301 or step S302.

[0079] S301. If the fan speed in stage i is greater than the fan speed in stage i-1, the heating power in stage i is greater than the heating power in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, the controller determines that the fan speed in stage i+1 is the sum of the fan speed in stage i and the fifth preset speed, and the heating power in stage i+1 is the sum of the heating power in stage i and the first preset power.

[0080] The condensate precipitation rate in stage i is determined based on the condensate precipitation amount and the duration of stage i, and the condensate precipitation rate in stage i-1 is determined based on the condensate precipitation amount and the duration of stage i-1.

[0081] It should be understood that when the fan speed in the i-th stage is greater than that in the (i-1)-th stage, the heating power in the i-th stage is greater than that in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is greater than or equal to that in the (i-1)-th stage, it means that the drying efficiency is also increasing as the fan speed and heating power increase. Therefore, the fan speed and heating power should be increased again in the next stage to keep the drying efficiency of the dryer at a high level.

[0082] S302. If the fan speed in stage i is greater than the fan speed in stage i-1, the heating power in stage i is greater than the heating power in stage i-1, and the condensate precipitation rate in stage i is less than the condensate precipitation rate in stage i-1, the controller determines that the fan speed in stage i+1 is the difference between the fan speed in stage i-1 and the sixth preset speed, and the heating power in stage i+1 is the difference between the heating power in stage i-1 and the second preset power.

[0083] It should be understood that when the fan speed in the i-th stage is greater than that in the (i-1)-th stage, the heating power in the i-th stage is greater than that in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is less than that in the (i-1)-th stage, it means that the drying efficiency decreases as the fan speed and heating power increase. Therefore, the fan speed and heating power should be reduced in the next stage to keep the drying efficiency of the dryer at a high level.

[0084] Figure 9 The technical solution shown brings at least the following beneficial effects: If the fan speed in stage i is greater than that in stage i-1, and the heating power in stage i is greater than that in stage i-1, then based on the changes in the condensate precipitation rate in stages i and i-1, the effect of simultaneously increasing the fan speed and heating power on the condensate precipitation rate can be determined. This allows for adjustments to the fan speed and heating power in the next stage, ensuring that the condensate precipitation rate remains at a relatively high level, thereby improving drying efficiency.

[0085] In some embodiments, such as Figure 10 As shown, the specific implementation of step S102 may also include step S303 or step S304.

[0086] S303. If the fan speed in stage i is greater than the fan speed in stage i-1, the heating power in stage i is less than the heating power in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, the controller determines that the fan speed in stage i+1 is the sum of the fan speed in stage i and the seventh preset speed, and the heating power in stage i+1 is the difference between the heating power in stage i and the third preset power.

[0087] It should be understood that when the fan speed in the i-th stage is greater than that in the (i-1)-th stage, the heating power in the i-th stage is less than that in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is greater than or equal to that in the (i-1)-th stage, it means that as the fan speed increases and the heating power decreases, the drying efficiency will increase. Therefore, in the next stage, the fan speed should continue to increase and the heating power should be decreased in order to keep the drying efficiency of the dryer at a high level.

[0088] S304. If the fan speed in stage i is greater than the fan speed in stage i-1, the heating power in stage i is less than the heating power in stage i-1, and the condensate precipitation rate in stage i is less than the condensate precipitation rate in stage i-1, the controller determines that the fan speed in stage i+1 is the difference between the fan speed in stage i-1 and the eighth preset speed, and the heating power in stage i+1 is the sum of the heating power in stage i-1 and the fourth preset power.

[0089] It should be understood that when the fan speed in the i-th stage is greater than that in the (i-1)-th stage, the heating power in the i-th stage is less than that in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is less than that in the (i-1)-th stage, it means that as the fan speed increases and the heating power decreases, the drying efficiency will decrease. Therefore, in the next stage, the fan speed should be reduced and the heating power increased in order to keep the drying efficiency of the dryer at a high level.

[0090] Figure 10 The technical solution shown brings at least the following beneficial effects: If the fan speed in stage i is greater than that in stage i-1, and the heating power in stage i is less than that in stage i-1, then based on the changes in the condensate precipitation rate in stages i and i-1, the effect of the increase in fan speed and the decrease in heating power on the condensate precipitation rate can be determined. This allows for adjustments to the fan speed and heating power in the next stage, ensuring that the condensate precipitation rate remains at a relatively high level, thereby improving drying efficiency.

[0091] In some embodiments, such as Figure 11 As shown, the specific implementation of step S102 may also include step S305 or step S306.

[0092] S305. If the fan speed in stage i is less than the fan speed in stage i-1, the heating power in stage i is less than the heating power in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, the controller determines that the fan speed in stage i+1 is the difference between the fan speed in stage i and the ninth preset speed, and the heating power in stage i+1 is the difference between the heating power in stage i and the fifth preset power.

[0093] It should be understood that when the fan speed in the i-th stage is less than the fan speed in the (i-1)-th stage, the heating power in the i-th stage is less than the heating power in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is greater than or equal to the condensate precipitation rate in the (i-1)-th stage, it means that as the fan speed and heating power decrease simultaneously, the drying efficiency will increase. Therefore, in the next stage, the fan speed and heating power should continue to decrease in order to keep the drying efficiency of the dryer at a high level.

[0094] S306. If the fan speed in stage i is less than the fan speed in stage i-1, the heating power in stage i is less than the heating power in stage i-1, and the condensate precipitation rate in stage i is less than the condensate precipitation rate in stage i-1, the controller determines that the fan speed in stage i+1 is the sum of the fan speed in stage i-1 and the tenth preset speed, and the heating power in stage i+1 is the sum of the heating power in stage i-1 and the sixth preset power.

[0095] It should be understood that when the fan speed in the i-th stage is less than the fan speed in the (i-1)-th stage, the heating power in the i-th stage is less than the heating power in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is less than the condensate precipitation rate in the (i-1)-th stage, it means that the drying efficiency will decrease as the fan speed and heating power decrease simultaneously. Therefore, the fan speed and heating power should be increased simultaneously in the next stage to keep the drying efficiency of the dryer at a high level.

[0096] Figure 11 The technical solution shown brings at least the following beneficial effects: If the fan speed in stage i is less than the fan speed in stage i-1, and the heating power in stage i is less than the heating power in stage i-1, then based on the changes in the condensate precipitation rate in stages i and i-1, it can be known that the simultaneous decrease in fan speed and heating power affects the condensate precipitation rate. This allows for changes in the fan speed and heating power in the next stage, ensuring that the condensate precipitation rate is kept as high as possible, thereby improving drying efficiency.

[0097] In some embodiments, such as Figure 12 As shown, the specific implementation of step S102 may also include step S307 or step S308.

[0098] S307. If the fan speed in stage i is less than the fan speed in stage i-1, the heating power in stage i is greater than the heating power in stage i-1, and the condensate precipitation rate in stage i is greater than or equal to the condensate precipitation rate in stage i-1, the controller determines that the fan speed in stage i+1 is the difference between the fan speed in stage i and the eleventh preset speed, and the heating power in stage i+1 is the sum of the heating power in stage i and the seventh preset power.

[0099] It should be understood that when the fan speed in the i-th stage is less than that in the (i-1)-th stage, the heating power in the i-th stage is greater than that in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is greater than or equal to that in the (i-1)-th stage, it means that as the fan speed decreases and the heating power increases, the drying efficiency will increase. Therefore, in the next stage, the fan speed should be further reduced while the heating power is increased in order to keep the drying efficiency of the dryer at a high level.

[0100] S308. If the fan speed in stage i is less than the fan speed in stage i-1, the heating power in stage i is greater than the heating power in stage i-1, and the condensate precipitation rate in stage i is less than the condensate precipitation rate in stage i-1, the controller determines that the fan speed in stage i+1 is the sum of the fan speed in stage i-1 and the twelfth preset speed, and the heating power in stage i+1 is the difference between the heating power in stage i-1 and the eighth preset power.

[0101] It should be understood that when the fan speed in the i-th stage is less than that in the (i-1)-th stage, the heating power in the i-th stage is greater than that in the (i-1)-th stage, and the condensate precipitation rate in the i-th stage is less than that in the (i-1)-th stage, it means that as the fan speed decreases and the heating power increases, the drying efficiency will decrease. Therefore, in the next stage, the fan speed should be increased while the heating power is decreased in order to keep the drying efficiency of the dryer at a high level.

[0102] Figure 12 The technical solution shown brings at least the following beneficial effects: If the fan speed in stage i is less than that in stage i-1, and the heating power in stage i is greater than that in stage i-1, then based on the changes in the condensate precipitation rate in stages i and i-1, it can be known that the decrease in fan speed and the increase in heating power affect the condensate precipitation rate. This allows for changes in the fan speed and heating power in the next stage, keeping the condensate precipitation rate as high as possible, thereby improving drying efficiency.

[0103] In some embodiments, the first preset speed to the twelfth preset speed may be the same or different, and the first preset power to the eighth preset power may be the same or different. This application does not limit this.

[0104] The following is based on Figure 7 and Figure 8 The illustrated embodiment exemplifies the working process of a clothes dryer performing a drying program: like Figure 13 As shown, the drying program is started, and the dryer begins running the drying program: (1) First, the fan starts working at the initial speed V0. After the fan runs for a preset time T, the controller calculates and stores the condensate precipitation rate L1 during this stage.

[0105] (2) The initial speed V0 is increased to the preset speed V1. The fan continues to work at speed V1 for a preset time T. The controller recalculates and stores the condensate precipitation rate L2 of this stage.

[0106] (3) If L2≥L1, then the fan speed in the next stage is determined to be V3=V2+preset speed, and step (1) is entered again.

[0107] (4) If L2 < L1, then the fan speed for the next stage is determined to be V3 = V1 - preset speed.

[0108] (5) The fan operates at a speed of V3 for a preset duration of T. The controller calculates and stores the condensate precipitation rate L3 during this stage.

[0109] (6) If L3≥L2, the fan speed in the next stage is determined to be the difference between V3 and the preset speed. Then, step (4) is entered again to calculate the condensate precipitation rate in the next stage.

[0110] (7) If L3 < L2, the fan speed in the next stage is determined to be the sum of V3 and the preset speed. Then, step (1) is entered again to calculate the condensate precipitation rate in the next stage.

[0111] (8) When the drying end conditions are met, the controller controls the dryer to end the drying program.
