Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

[0037] The embodiments of the present application provide a drying judgment method, device, storage medium and clothing processing equipment, which can automatically and accurately judge the drying condition of clothes and realize the drying of clothes. The drying judgment method and device will be described in detail below.

[0038] See also Figure 1 , Figure 1 A flow chart of a drying judgment method provided in an embodiment of the present application, the method is applied to a clothing processing device, the clothing processing device has the functions of a washing machine and a dryer, and can automatically wash, spin and dry clothing. The clothing processing device is provided with a water heating pipe, a condensation valve and a drying channel. In addition, the clothing processing device is also provided with a drum, and the water heating pipe and the condensation valve are arranged inside the clothing processing device near the drum, wherein the water heating pipe is used to dry clothing, and the condensation valve is used to cool down the dried clothing.

[0039] In an embodiment of the present application, a first temperature sensor and a second temperature sensor are further provided on the clothing processing device. The first temperature sensor is used to obtain the temperature of the water heating pipe, and the second temperature sensor is used to obtain the temperature of the air outlet of the drying tunnel.

[0040] Furthermore, a drying determination method includes the following contents:

[0041] 101. Obtain temperature information of the water heating pipe in a drying stage, wherein the temperature information includes an initial temperature value and a maximum temperature value.

[0042] 102. Obtain a first time required for the temperature to rise from the initial temperature value to the maximum temperature value, and calculate a comprehensive temperature compensation time of the drying stage based on the initial temperature value, the maximum temperature value, and the first time.

[0043] During the drying stage of the clothing processing equipment, the washed and spun-dried clothes need to be dried. During the drying stage, the water heating pipe is opened, the condensing valve is closed, and the heat generated by the water heating pipe is used to dry the clothes in the drum. The temperature information of the water heating pipe is obtained through a first temperature sensor corresponding to the water heating pipe, and the corresponding time is obtained in combination with a timer or other electronic components that calculate time.

[0044] In the embodiment of the present application, the temperature information of the water heating pipe obtained in the drying stage includes an initial temperature value and a maximum temperature value. The initial temperature value is represented by the symbol T0, and the maximum temperature value is represented by the symbol T max To express.

[0045] Get the initial temperature value T0 of the water heating pipe, and based on the initial temperature value T0, continue to get the temperature value of the water heating pipe until the maximum temperature value T max , the temperature of the water heating pipe rises from the initial temperature value T0 to the maximum temperature value T max The time required is recorded as the first time t.

[0046] In an embodiment of the present application, when obtaining the temperature value of the water heating pipe, a filtered value is collected every 10 seconds from the first temperature sensor corresponding to the water heating pipe at the ms level, and the obtained value is recorded.

[0047] Optionally, before obtaining the temperature information of the water heating pipe in the drying stage, the temperature information includes the initial temperature value and the maximum temperature value, it also includes: obtaining the air outlet temperature of the drying channel, and when the air outlet temperature is lower than the preset opening temperature of the water heating pipe, controlling the clothing processing equipment to enter the drying stage.

[0048] In the embodiment of the present application, the air outlet temperature is represented by the symbol T n The preset water heating pipe opening temperature is represented by the symbol T m To express.

[0049] Then, before obtaining the temperature information of the water heating pipe in the drying stage, obtain the outlet temperature T of the drying tunnel. n , at the outlet temperature T n Lower than the preset water heating pipe opening temperature T m When the water temperature reaches 400 °C, it enters the drying stage, controls the water heating pipe to open, and closes the condensing valve.

[0050] The outlet temperature of the drying tunnel is obtained by the second temperature sensor, which is denoted as T n , and set the water heating pipe opening temperature, recorded as T m When the outlet temperature T n Less than the water heating pipe opening temperature T mWhen the temperature at the air outlet is T n Greater than or equal to the water heating pipe opening temperature T m When the water heating pipe is turned off.

[0051] For example, set the water heating pipe opening temperature T m is 110℃, when the outlet temperature T n When the temperature is lower than 110℃, turn on the water heating pipe and close the condensation valve. n When the temperature is greater than or equal to 110℃, turn off the water heating pipe.

[0052] For example, set the water heating pipe opening temperature T m is 110℃ and 120℃, when the outlet temperature T n When the temperature is lower than 110℃, turn on the water heating pipe and close the condensation valve. n When the temperature is greater than or equal to 120℃, turn off the water heating pipe.

[0053] In the embodiment of the present application, the set standard initial temperature is represented by the symbol T1, and the comprehensive temperature compensation time is represented by the symbol t b It is represented by, where the comprehensive temperature compensation time t b It is the sum of the first time t and the time compensation t0, wherein the time compensation t0 is the time for converting the initial temperature value T0 into the standard initial temperature T1.

[0054] For example, if the standard initial temperature T1 is set to 20°C, then the time compensation t0 is the time required to convert the initial temperature value T0 to 20°C.

[0055] Optionally, solve the first difference a between the initial temperature value T0 and the standard initial temperature T1, and the maximum temperature value T max A second difference b between the second difference b and the initial temperature value T0 is obtained, and a ratio x of the second difference b and the first time t is solved, and the time compensation t0 is the product of the ratio x, the first difference a and a preset temperature compensation coefficient k.

[0056] In the embodiment of the present application, the calculation formula of the time compensation t0 is: t0 = (T0-T1)*[t / (T max -T0)]*k, where k is the temperature compensation coefficient.

[0057] Optionally, set the reference temperature T c , based on the initial temperature value T0 and the reference temperature T c The numerical comparison result is used to determine the value of the preset temperature compensation coefficient k.

[0058] For example, the reference temperature T cIt is set to 35°C, and when the initial temperature value T0>35°C, k is 0.82, and when the initial temperature value T0≤35°C, k is 1.

[0059] Based on the formula t0 = (T0-T1)*[t / (T max -T0)]*k, where the difference between T0 and T1 is the first difference a, T max -T0 is the second difference b, t / (T max -T0) is x.

[0060] For example, the standard initial temperature T1 is 20°C and the maximum temperature T max is 55°C, and the initial temperature value T0≤35°C, k is 1, then t0=(T0-20)*[t / (55-T0)]*1, that is, t0=a*x.

[0061] Further, in the embodiment of the present application, after the time compensation t0 is calculated, the comprehensive temperature compensation time t b , the relationship between the first time t and the time compensation t0 is: b =t+t0.

[0062] 103. Based on the comprehensive temperature compensation time, calculate a second time required for the water heating pipe to continue drying after the temperature reaches the maximum temperature value.

[0063] When the temperature of the water heating pipe reaches the maximum value T max Afterwards, the clothes in the drum may not be dried yet, therefore, it is necessary to continue drying the clothes in the drum to avoid the situation where the clothes cannot be dried. The drying time needs to be appropriate. If the drying time is too long, the clothes will be damaged. Therefore, the drying time is calculated and confirmed based on the comprehensive temperature compensation time.

[0064] In the embodiment of the present application, after the drying is started, the temperature of the water heating pipe reaches T max After that, the drying time needs to be continued for the second time, recorded as t x , can be obtained by calculating the comprehensive temperature compensation time t b Perform quadratic equation fitting to obtain the second time t x , the second time t x And the comprehensive temperature compensation time t b The relationship satisfies the fitting formula: t x =-0.077*t b *t b +16.8*t b -258.

[0065] Optionally, the second time tx and the comprehensive temperature compensation time t b There are multi-order polynomial / exponential function / logarithmic function / linear relationship between them.

[0066] Optionally, the second time t x and the comprehensive temperature compensation time t b Other types of relationship expressions may also be satisfied, which will not be described here.

[0067] 104. Acquire the maximum value of the temperature of the water heating pipe entering a stable state during the second time as a steady-state maximum temperature value, and determine the drying process of the drying stage based on the steady-state maximum temperature value, wherein the drying process includes ending drying and continuing drying.

[0068] In the embodiment of the present application, the maximum steady-state temperature is set by the symbol T xmax This step includes: determining the time for the water heating pipe to reach the maximum steady-state temperature value based on the comprehensive temperature compensation time, calculating the judgment time based on the time point when the temperature of the water heating pipe reaches the maximum temperature value, and starting to judge the maximum steady-state temperature value when the judgment time is reached.

[0069] At the second time t x In the drying stage, the time t is compensated according to the comprehensive temperature. b The time difference is defined from the maximum temperature value T max After reaching the maximum steady-state temperature T, the maximum steady-state temperature T xmax time point.

[0070] For example: When the comprehensive temperature compensation time t b <25, start to judge the maximum steady-state temperature T after 10 minutes xmax ; When 25≤comprehensive temperature compensation time t b <33, start to judge the maximum steady-state temperature T after 20 minutes xmax ; When 33≤comprehensive temperature compensation time t b <40, start to judge the maximum steady-state temperature T after 30 minutes xmax ; When the comprehensive temperature compensation time t b ≥40, start to judge the maximum steady-state temperature value T after 50 minutes xmax .

[0071] Determine the maximum steady-state temperature T xmax The method can be to compare the slope before and after in real time, and when the rising trend turns to a falling trend or the value change trend within 5 minutes is 0, it is considered that the inflection point temperature 5 minutes ago is the steady-state maximum temperature value T of the water heating pipe entering a stable state. xmax .

[0072] The above is used to determine the maximum steady-state temperature T xmax When , the value change trend within 5 minutes is set, and the 5 minutes time can be set to other time values ​​according to actual conditions.

[0073] Optionally, in this step, based on a preset filtering time, the steady-state maximum temperature value is filtered to obtain a filtered temperature value, and based on the filtered temperature value and the steady-state maximum temperature value, the drying process of the drying stage is determined, and the drying process includes ending drying and continuing drying.

[0074] In the embodiment of the present application, the set filtering temperature value is represented by the symbol Tt. Then, after determining the steady-state maximum temperature value T xmax Afterwards, the value of the filtered temperature value Tt can be obtained by filtering for 1 minute.

[0075] Optionally, the absolute value of the difference between the steady-state maximum temperature value and the filtered temperature value is calculated to determine whether the absolute value is greater than a preset target temperature value. If so, the drying is terminated and the cooling phase is entered; if not, the drying is continued within a second time.

[0076] Calculate the maximum steady-state temperature T xmax The absolute value ΔT of the difference between the filtered temperature value Tt and ΔT is numerically compared with the preset target temperature value μ. When ΔT ≥ μ, the drying process is completed, that is, the drying is ended and the cooling stage is entered, then the water heating pipe is closed and the condensing valve is opened.

[0077] The filtered temperature value Tt is the second time t x The maximum steady-state temperature T xmax After the judgment, the current real-time temperature value, the filtered temperature value Tt can be obtained by filtering for 1 minute, and the preset target temperature value μ lasts for more than 1 minute, then the drying stage process is terminated in advance and the cooling stage is directly entered, otherwise the drying is continued within the second time, that is, the second time t x After the time runs out, it enters the cooling phase.

[0078] The value of the preset target temperature value μ can be obtained according to load test data or according to a fitting function.

[0079] The drying judgment method of the embodiment of the present application is applied to a clothing processing device, which is provided with a water heating pipe and a drying channel. The method comprises: obtaining the temperature information of the water heating pipe in the drying stage, the temperature information comprising an initial temperature value and a maximum temperature value; obtaining the first time required for the temperature to rise from the initial temperature value to the maximum temperature value, and calculating the comprehensive temperature compensation time of the drying stage based on the initial temperature value, the maximum temperature value and the first time; calculating the second time required for the temperature of the water heating pipe to continue drying after reaching the maximum temperature value based on the comprehensive temperature compensation time; obtaining the maximum value of the temperature of the water heating pipe entering a stable state during the second time as a steady-state maximum temperature value, and determining the drying process of the drying stage based on the steady-state maximum temperature value, and the drying process comprises ending drying and continuing drying.

After entering the drying stage, the cloth is loosened. The cloth is loosened in one circle clockwise, one circle counterclockwise, and then one circle clockwise. After the cloth is loosened, weigh and record the LD value. Then the inner drum rotates and stops rotating after a certain period of time.

If so, enter the empty drum process and continue drying for 10 minutes; otherwise, enter the second time of continued drying. x stage, and determine the maximum steady-state temperature T xmax The absolute value of the difference between the filtered temperature value Tt and the preset target temperature value μ, that is, ΔT = |T xmax -T t |, and compare the values ​​of ΔT and μ. If ΔT ≥ μ, enter the cooling stage, close the water heating pipe, and open the condensing valve; if ΔT < μ, determine the second time t x Is the time completed?

[0109] For example, the standard initial temperature T1 is 20°C and the maximum temperature T max is 55°C, and the initial temperature value T0≤35°C, k is 1, then t0=(T0-20)*[t / (55-T0)]*1, that is, t0=a*x.

[0110] Further, in the embodiment of the present application, after the time compensation t0 is calculated, the comprehensive temperature compensation time t b , the relationship between the first time t and the time compensation t0 is:b =t+t0.

Therefore, the drying time is calculated and confirmed based on the comprehensive temperature compensation time.

[0113] In the embodiment of the present application, after the drying is started, the temperature of the water heating pipe reaches T max After that, the drying time needs to be continued for the second time, recorded as t x , can be obtained by calculating the comprehensive temperature compensation time t b Perform quadratic equation fitting to obtain the second time t x , the second time t x And the comprehensive temperature compensation time t b The relationship satisfies the fitting formula: t x =-0.077*t b *t b +16.8*t b -258.

[0114] Optionally, the second time t x and the comprehensive temperature compensation time t b There are multi-order polynomial / exponential function / logarithmic function / linear relationships between them.

[0115] Optionally, the second time t x and the comprehensive temperature compensation time t b Other types of relationship expressions may also be satisfied, which will not be described here.

[0116] The determination unit 204 is used to obtain the maximum value of the temperature of the water heating pipe entering a stable state during the second time as a steady-state maximum temperature value, and determine the drying process of the drying stage based on the steady-state maximum temperature value, wherein the drying process includes ending drying and continuing drying.

[0117] In the embodiment of the present application, the maximum steady-state temperature is set by the symbol T xmaxThis step includes: determining the time for the water heating pipe to reach the maximum steady-state temperature value based on the comprehensive temperature compensation time, calculating the judgment time based on the time point when the temperature of the water heating pipe reaches the maximum temperature value, and starting to judge the maximum steady-state temperature value when the judgment time is reached.

[0118] At the second time t x In the drying stage, the time t is compensated according to the comprehensive temperature. b The time difference is defined from the maximum temperature value T max After reaching the maximum steady-state temperature T, the maximum steady-state temperature T xmax time point.

[0119] For example: When the comprehensive temperature compensation time t b <25, start to judge the maximum steady-state temperature T after 10 minutes xmax ; When 25≤comprehensive temperature compensation time t b <33, start to judge the maximum steady-state temperature T after 20 minutes xmax ; When 33≤comprehensive temperature compensation time t b <40, start to judge the maximum steady-state temperature T after 30 minutes xmax ; When the comprehensive temperature compensation time t b ≥40, start to judge the maximum steady-state temperature value T after 50 minutes xmax .

[0120] Determine the maximum steady-state temperature T xmax The method can be to compare the slope before and after in real time, and when the rising trend turns to a falling trend or the value change trend within 5 minutes is 0, it is considered that the inflection point temperature 5 minutes ago is the steady-state maximum temperature value T of the water heating pipe entering a stable state. xmax .

[0121] The above is used to determine the maximum steady-state temperature T xmax When , the value change trend within 5 minutes is set, and the 5 minutes time can be set to other time values ​​according to actual conditions.

[0122] Optionally, in this unit, based on a preset filtering time, the steady-state maximum temperature value is filtered to obtain a filtered temperature value, and based on the filtered temperature value and the steady-state maximum temperature value, the drying process of the drying stage is determined, and the drying process includes ending drying and continuing drying.

[0123] In the embodiment of the present application, the set filtering temperature value is represented by the symbol Tt. Then, after determining the steady-state maximum temperature value T xmax Afterwards, the value of the filtered temperature value Tt can be obtained by filtering for 1 minute.

[0124] Optionally, the absolute value of the difference between the steady-state maximum temperature value and the filtered temperature value is calculated to determine whether the absolute value is greater than a preset target temperature value. If so, the drying is terminated and the cooling phase is entered; if not, the drying is continued within a second time.

[0125] Calculate the maximum steady-state temperature T xmax The absolute value ΔT of the difference between the filtered temperature value Tt and ΔT is numerically compared with the preset target temperature value μ. When ΔT ≥ μ, the drying process is completed, that is, the drying is ended and the cooling stage is entered, then the water heating pipe is closed and the condensing valve is opened.

[0126] The filtered temperature value Tt is the second time t x The maximum steady-state temperature T xmax After the judgment, the current real-time temperature value, the filtered temperature value Tt can be obtained by filtering for 1 minute, and the preset target temperature value μ lasts for more than 1 minute, then the drying stage process is terminated in advance and the cooling stage is directly entered, otherwise the drying is continued within the second time, that is, the second time t x After the time runs out, it enters the cooling phase.

[0127] The value of the preset target temperature value μ can be obtained according to load test data or according to a fitting function.
