[0067] The control method of the dryer according to the embodiments of the present application will be described below. Figure 1 The control method of the dryer according to the embodiments of the present application will be described below.

[0068] The dryer is used for treating clothes to dry the clothes, so as to avoid long time airing. The dryer has a drying chamber, after the clothes to be dried are put into the drying chamber, dry hot air is introduced into the clothes to be dried, so as to quickly take away the moisture on the clothes.

[0069] The control method of the dryer of the embodiment of the present application comprises: step 110, step 120, step 130 and step 140.

[0070] Step 110, receiving a first input of a user;

[0071] In this step, the first input is used to determine a target working mode.

[0072] The first input can be at least one of the following modes:

[0073] Firstly, the first input can be a touch operation, including but not limited to a click operation, a sliding operation and a pressing operation, etc.

[0074] In this embodiment, the first input of the user can be a touch operation of the user on a display area of a display screen of the dryer.

[0075] For example, the display area of the display screen of the dryer displays a plurality of function controls, and the working mode can be selected by clicking the function controls.

[0076] Secondly, the first input can be an entity key input.

[0077] In this embodiment, the machine body of the dryer is provided with entity keys corresponding to the working modes, and the first input of the user can be an input of pressing the corresponding entity keys; the first input can also be a combination operation of pressing a plurality of entity keys at the same time.

[0078] Thirdly, the first input can be a voice input.

[0079] In this embodiment, when the dryer receives a voice such as "intelligent drying", the intelligent drying mode is triggered to enter.

[0080] Of course, in other embodiments, the first input can also be in other forms, including but not limited to character input, etc., which can be determined according to actual needs, and the embodiments of the present application are not limited thereto.

[0081] Step 120, in response to the first input, entering the target working mode, and controlling the heater of the dryer to heat at a first power;

[0082] It should be noted that in the target working mode, the dryer has an initial heating power, and the initial heating power is the first power.

[0083] In some embodiments, the heater has a first power P1, a second power P2 and a third power P3, P1

[0084] Controlling the heater to heat at a lower first power in the initial stage can prevent damage to the laundry.

[0085] The target working mode can include one working mode, or a combination of multiple working modes.

[0086] Step 130, in the target working mode, obtaining humidity information and temperature information of the dryer;

[0087] It should be noted that the dryer is provided with a temperature sensor and a humidity sensor, wherein the above-mentioned temperature information and humidity information correspond to the temperature and humidity of different regions according to the different positions of the temperature sensor and the humidity sensor.

[0088] In some embodiments, the temperature sensor can be installed in the drying chamber of the dryer, and correspondingly, the temperature information is the temperature information of the drying chamber.

[0089] In other embodiments, the temperature sensor can be installed at the air outlet of the drying chamber, and correspondingly, the temperature information is the temperature information at the air outlet.

[0090] In some embodiments, the humidity sensor can be installed in the drying chamber of the dryer, and correspondingly, the humidity information is the humidity information of the drying chamber.

[0091] In other embodiments, the humidity sensor can be installed at the air outlet of the drying chamber, and correspondingly, the humidity information is the humidity information at the air outlet.

[0092] The temperature sensor continuously monitors the temperature information of the corresponding region to obtain multiple temperature information in time sequence; the humidity sensor continuously monitors the humidity information of the corresponding region to obtain multiple humidity information in time sequence.

[0093] Step 140, based on the humidity information and the temperature information, adjusting the heating power of the heater on the basis of the first power.

[0094] By analyzing the temperature information and the humidity information, the load in the dryer can be determined, and based on the load, the current required heating power can be obtained, and accordingly, the heating power of the heater can be adjusted on the basis of the initial first power.

[0095] In other words, the control method of the dryer according to the embodiments of the present application, after the user selects the target working mode, the heating power of the dryer is not determined and kept unchanged based on the working mode alone as in the related art, but needs to be automatically adjusted after comprehensive judgment in combination with the temperature and humidity information, so that the most suitable heating power can be used for working in combination with the user demand and the actual load.

[0096] The control method of the dryer according to the embodiments of the present application, after the user selects the target working mode, the dryer starts with a lower initial heating power, and automatically adjusts in combination with the target working mode and the temperature and humidity information, fully combining the user demand and the actual load, so as to reduce power consumption and damage to clothes while ensuring efficient drying.

[0097] In some embodiments, the adjusting the heating power of the heater based on the first power includes: adjusting the heating power of the heater based on the first power based on the humidity information, the temperature information and the target working mode.

[0098] It can be understood that in this embodiment, the finally determined heating power of the heater not only considers the temperature and humidity information, but also combines the currently determined working mode, which means that even for the same load, the final heating power is different if the working mode is different.

[0099] In some embodiments, the adjusting the heating power of the heater based on the first power can include adjusting the heating power of the heater based on the first power to the end of drying, so that the logic of the whole power adjustment is relatively simple, and the failure rate is low.

[0100] In some embodiments, the target working mode can be a combination of multiple working modes, and the target working mode can include an intelligent working mode and a fast working mode; or the target working mode can include an intelligent working mode and a soft working mode.

[0101] In this embodiment, the dryer in the intelligent working mode will automatically adjust the heating power based on the temperature and humidity information, and if the fast working mode is also selected, the heating power will be appropriately increased according to the specific situation, and if the soft working mode is also selected, the heating power will be appropriately reduced according to the specific situation.

[0102] In some embodiments, the step 130 of acquiring the humidity information and the temperature information of the dryer includes: acquiring the humidity information and the temperature information of the dryer corresponding to a plurality of collection periods respectively.

[0103] The plurality of collection periods can be arranged in time sequence, and each collection period can collect one data, or each collection period can collect multiple data.

[0104] It can be understood that the temperature sensor and the humidity sensor continuously collect data, and in some embodiments, in order to reduce the amount of data processing and without affecting the accuracy of identification, the data in the target period is averaged as a temperature information or a humidity information.

[0105] For example, for the data collected by the temperature sensor, each collection period is 10 seconds, that is, the average value is taken every 10 seconds to obtain a temperature information; for the data collected by the humidity sensor, each collection period is 10 seconds, that is, the average value is taken every 10 seconds to obtain a humidity information.

[0106] It should be noted that the plurality of temperature information and the plurality of humidity information correspond to each other in time, for example, a temperature information is obtained every 10 seconds, and the corresponding humidity information is also obtained.

[0107] In some embodiments, step 110 includes obtaining a plurality of temperature information and a plurality of humidity information of the drying chamber of the dryer in time sequence.

[0108] In some embodiments, the plurality of temperature information is temperature information of the dryer after starting for a first target time length; and the plurality of humidity information is humidity information of the dryer after starting for the first target time length.

[0109] In other words, step 110 can include obtaining a plurality of temperature information and a plurality of humidity information of the dryer in time sequence after starting for a first target time length.

[0110] It can be understood that when the dryer is just started, its internal state is unstable, and the corresponding temperature information and humidity information have little reference value. After the first target time length, the internal state is basically stable, and the corresponding temperature information and humidity information have a judgment value.

[0111] The first target time length can be a preset fixed value, such as 30 seconds-2 minutes, and the first target time length can be 1 minute.

[0112] Alternatively, the first target time length can be determined based on the weight of the load (the clothes to be dried), such as obtaining the weight information collected by the gravity sensor, and determining the corresponding first target time length based on the weight information.

[0113] Based on the humidity information and the temperature information, the heating power of the heater is adjusted based on the first power, including:

[0114] Based on the plurality of temperature information, a target temperature gradient is determined, and based on the plurality of humidity information, a target humidity gradient is determined.

[0115] Based on the target temperature gradient and the target humidity gradient, the heating power of the heater is adjusted based on the first power.

[0116] On the basis of obtaining the plurality of temperature information in time sequence and the plurality of humidity information in time sequence, the target temperature gradient can be determined by the plurality of temperature information, and the target humidity gradient can be determined by the plurality of humidity information.

[0117] In some embodiments, the target temperature gradient is determined based on the plurality of temperature information, including: taking the difference between two temperature information adjacent in time sequence as the target temperature gradient.

[0118] In actual implementation, the target temperature gradient is ΔT, ΔT=T a -T a-1 , T a is the temperature information acquired this time, T a-1 is the temperature information acquired last time.

[0119] This way, the target temperature gradient obtained by taking the difference between the current acquired temperature information and the previous acquired temperature information can reflect the current temperature change, which helps to achieve high sensitivity control.

[0120] The target humidity gradient is determined based on the plurality of humidity information, including: taking the difference between two humidity information adjacent in time sequence as the target humidity gradient.

[0121] In actual implementation, the target humidity gradient is ΔRh, ΔRh=Rh a -Rh a-1 , Rh a is the humidity information acquired this time, Rh a-1 is the humidity information acquired last time.

[0122] This way, the target humidity gradient obtained by taking the difference between the current acquired humidity information and the previous acquired humidity information can reflect the current humidity change, which helps to achieve high sensitivity control.

[0123] The target temperature gradient is used to represent the current temperature change, and the temperature change can reflect the amount of load; the target humidity gradient is used to represent the current humidity change, and the humidity change can more accurately reflect the current moisture of the load.

[0124] In the related art, the drying power is controlled by the temperature value or the humidity value, which cannot reflect the amount of load and expresses the current moisture of the load very roughly, so that the subsequent power control accuracy is not enough and the response is sluggish.

[0125] The control method of the dryer in the embodiments of the present application determines the heating power of the heater through the target temperature gradient and the target humidity gradient, and controls the heater to work according to the heating power, which can reduce power consumption and damage to clothes while ensuring efficient drying.

[0126] In some embodiments, the heater has a first power P1, a second power P2 and a third power P3, P1

[0127] The heater can include multiple sub-heaters, such as the heater can include a first sub-heater and a second sub-heater, the first sub-heater has a rated power of the first power P1, the second sub-heater has a rated power of the second power P2, the first power P1 + the second power P2 = the third power P3.

[0128] Controlling the heater to heat at the first power includes: controlling the first sub-heater to turn on and controlling the second sub-heater to turn off.

[0129] Controlling the heater to heat at the second power includes: controlling the second sub-heater to turn on and controlling the first sub-heater to turn off.

[0130] Controlling the heater to heat at the third power includes: controlling the first sub-heater to turn on and controlling the second sub-heater to turn on.

[0131] Or the heater can include more sub-heaters, each sub-heater has a different power, and when heating is needed, only the corresponding power sub-heater is turned on each time.

[0132] The step of adjusting the heating power of the heater on the basis of the first power based on the target temperature gradient and the target humidity gradient can include:

[0133] In the case that the target temperature gradient is not less than a first target value and the target humidity gradient is less than a second target value, the heater is controlled to heat at the first power or the second power based on the target working mode until the drying ends.

[0134] The first target value can be a preset fixed value, such as 0.1-1 degree Celsius, and the first target value can be 0.5 degrees Celsius.

[0135] Alternatively, the first target value can be determined based on the weight of the load (the clothes to be dried), such as obtaining weight information collected by a gravity sensor, and determining the corresponding first target value based on the weight information.

[0136] Alternatively, the first target value can also be related to the sensitivity of the temperature sensor, and the higher the sensitivity of the temperature sensor, the smaller the first target value.

[0137] The second target value can be a preset fixed value, such as 0.1%-3%, and the second target value can be 1%.

[0138] Alternatively, the second target value can be determined based on the weight of the load (the clothes to be dried), such as obtaining weight information collected by a gravity sensor, and determining the corresponding second target value based on the weight information.

[0139] Alternatively, the second target value can also be related to the sensitivity of the humidity sensor, the higher the sensitivity of the humidity sensor, the smaller the second target value.

[0140] When the target temperature gradient is not less than the first target value, it indicates that the temperature in the drying chamber rises relatively fast; when the target humidity gradient is less than the second target value, it indicates that the humidity in the drying chamber drops slowly. This indicates that the load in the drying chamber is relatively small, or the load is relatively large, but the load is relatively dry.

[0141] At this time, the heater is controlled to heat to the end of drying at a relatively small first power or a second power, which can relatively quickly realize drying without damaging the clothes and with low power consumption.

[0142] The specific power selection can be determined according to the target working mode.

[0143] Based on the target working mode, the heater is controlled to heat to the end of drying at the first power or the second power, including: in the case that the dryer is in the gentle working mode, the heater is controlled to heat to the end of drying at the first power; in the case that the dryer is in the fast working mode, the heater is controlled to heat to the end of drying at the second power.

[0144] In other words, in the case that the target temperature gradient is not less than the first target value and the target humidity gradient is less than the second target value, the load in the drying chamber is relatively small, or the load is relatively large, but the moisture content is low.

[0145] If the user selects the gentle working mode, the minimum first power can be used, and the dehumidification effect is relatively gentle, and the damage to the load (clothes) is small; if the user selects the fast working mode, the relatively larger second power can be used, at this time, the drying effect is relatively obvious, the drying time is short, and the damage to the load (clothes) is small compared with the third power.

[0146] In the related art, if it is determined to be the fast working mode, the maximum third power is directly selected, so that the clothes damage is large, and the speed improvement is limited compared with the scheme of the present application.

[0147] On the other hand, after the heating power is determined, the corresponding heating power is directly used to heat to the end of drying, so that the control logic is relatively simple.

[0148] In some embodiments, the heater has a first power P1, a second power P2 and a third power P3, P1

[0149] The heater can include multiple sub-heaters, such as the heater can include a first sub-heater and a second sub-heater, the first sub-heater has a rated power of a first power P1, the second sub-heater has a rated power of a second power P2, the first power P1 + the second power P2 = a third power P3.

[0150] Controlling the heater to heat at the first power includes: controlling the first sub-heater to turn on and controlling the second sub-heater to turn off.

[0151] Controlling the heater to heat at the second power includes: controlling the second sub-heater to turn on and controlling the first sub-heater to turn off.

[0152] Controlling the heater to heat at the third power includes: controlling the first sub-heater to turn on and controlling the second sub-heater to turn on.

[0153] Or the heater can include more sub-heaters, each sub-heater has a different power, and when heating is needed, only the corresponding power sub-heater is turned on each time.

[0154] The step of adjusting the heating power of the heater on the basis of the first power based on the target temperature gradient and the target humidity gradient includes:

[0155] In the case that the target temperature gradient is not less than a first target value and the target humidity gradient is not less than a second target value, the heater is controlled to heat at the second power until the drying ends.

[0156] The first target value can be a preset fixed value, such as 0.1-1 degree Celsius, and the first target value can be 0.5 degrees Celsius.

[0157] Alternatively, the first target value can be determined based on the weight of the load (the clothes to be dried), such as obtaining weight information collected by a gravity sensor, and determining the corresponding first target value based on the weight information.

[0158] Alternatively, the first target value can also be related to the sensitivity of the temperature sensor, and the higher the sensitivity of the temperature sensor, the smaller the first target value.

[0159] The second target value can be a preset fixed value, such as 0.1%-3%, and the second target value can be 1%.

[0160] Alternatively, the second target value can be determined based on the weight of the load (the clothes to be dried), such as obtaining weight information collected by a gravity sensor, and determining the corresponding second target value based on the weight information.

[0161] Alternatively, the second target value can also be related to the sensitivity of the humidity sensor, and the higher the sensitivity of the humidity sensor, the smaller the second target value.

[0162] In the case that the target temperature gradient is not less than a first target value, it indicates that the temperature in the drying chamber rises relatively fast; in the case that the target humidity gradient is not less than a second target value, it indicates that the humidity in the drying chamber drops fast. This indicates that the load in the drying chamber is relatively small and the moisture content is high.

[0163] At this time, the heater is controlled to heat to the end of drying at the second power relative to the second power in the intermediate gear, relatively fast drying can be achieved without damaging the clothes, and the power consumption is low.

[0164] It should be noted that in this case, whether the dryer is in a soft working mode or a fast working mode, the heater is controlled to heat to the end of drying at the second power.

[0165] On the other hand, after determining the heating power, directly heating to the end of drying at the corresponding heating power, so that the control logic is relatively simple.

[0166] In some embodiments, the heater has a first power P1, a second power P2 and a third power P3, P1

[0167] The heater can include a plurality of sub-heaters, such as the heater can include a first sub-heater and a second sub-heater, the rated power of the first sub-heater is the first power P1, the rated power of the second sub-heater is the second power P2, the first power P1 + the second power P2 = the third power P3.

[0168] Controlling the heater to heat at the first power includes: controlling the first sub-heater to be turned on and controlling the second sub-heater to be turned off.

[0169] Controlling the heater to heat at the second power includes: controlling the second sub-heater to be turned on and controlling the first sub-heater to be turned off.

[0170] Controlling the heater to heat at the third power includes: controlling the first sub-heater to be turned on and controlling the second sub-heater to be turned on.

[0171] Or the heater can include more sub-heaters, each sub-heater has different power, when heating is needed, only the corresponding power sub-heater is turned on each time.

[0172] The step of adjusting the heating power of the heater on the basis of the first power based on the target temperature gradient and the target humidity gradient includes:

[0173] In the case that the target temperature gradient is less than a first target value, the heater is controlled to heat at the second power;

[0174] Based on the target humidity gradient and the target mode, the heater is controlled to heat to the end of drying at the second power or the third power.

[0175] The first target value can be a preset fixed value, such as 0.1-1 Celsius degree. The first target value can be 0.5 Celsius degree.

[0176] Alternatively, the first target value can be determined based on the weight of the load (the clothes to be dried), such as obtaining weight information collected by a gravity sensor, and determining the corresponding first target value based on the weight information.

[0177] Alternatively, the first target value can also be related to the sensitivity of the temperature sensor. The higher the sensitivity of the temperature sensor, the smaller the first target value.

[0178] When the target temperature gradient is less than the first target value, it indicates that the temperature in the drying chamber rises slowly. This indicates that the load in the drying chamber is too much.

[0179] At this time, the heater is controlled to heat to the end of drying at the second power or the third power, which can meet the needs of the multi-load without damaging the clothes, relatively quickly realize drying, and low power consumption.

[0180] The specific power selection can be determined according to the target humidity gradient and the current target working mode of the dryer.

[0181] Based on the target humidity gradient and the target working mode, the heater is controlled to heat to the end of drying at the second power or the third power, including:

[0182] When the target humidity gradient is not less than the second target value and the dryer is in the gentle working mode, the heater is controlled to heat to the end of drying at the second power;

[0183] When the target humidity gradient is less than the second target value and the dryer is in the gentle working mode, the heater is controlled to heat to the target humidity gradient is not less than the second target value, and then switch to the second power to the end of drying;

[0184] When the dryer is in the fast working mode, the heater is controlled to heat to the end of drying at the third power.

[0185] The second target value can be a preset fixed value, such as 0.1%-3%, and the second target value can be 1%.

[0186] Alternatively, the second target value can be determined based on the weight of the load (the clothes to be dried), such as obtaining weight information collected by a gravity sensor, and determining the corresponding second target value based on the weight information.

[0187] Alternatively, the second target value can also be related to the sensitivity of the humidity sensor. The higher the sensitivity of the humidity sensor, the smaller the second target value.

[0188] If the target humidity gradient is not less than the second target value, it indicates that the humidity in the drying chamber decreases quickly, and it is determined that the load is much and the moisture content is low. If the user selects the soft working mode, the second power is used to run, the dehumidification effect is relatively soft, and the damage to the load (clothes) is small. If the user selects the fast working mode, the third power is used to run, and the drying effect is relatively obvious, and the drying time is short.

[0189] If the target humidity gradient is less than the second target value, it indicates that the humidity in the drying chamber decreases quickly, and it is determined that the load is much and the moisture content is high. If the user selects the soft working mode, the third power is used to run to dehumidify quickly, the dehumidification effect is good, and when the target humidity gradient is not less than the second target value, it indicates that the humidity in the drying chamber decreases quickly, and it is determined that the moisture content of the load is low. The heater is controlled to heat at the second power until the drying is completed, the dehumidification effect is relatively soft, and the damage to the load (clothes) is small. If the user selects the fast working mode, the third power is used to run, and the drying effect is relatively obvious, and the drying time is short.
