Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the accompanying drawings. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

According to an embodiment of the present invention, a drying control method is provided, as shown in fig. 1, which is a schematic flow chart of an embodiment of the method of the present invention. The drying control method may include: step S110 to step S130.

At step S110, the moisture content of the laundry is acquired. For example: and acquiring the moisture content of the clothes in the inner drum of the washing and drying integrated machine to be controlled after the dewatering process or in the drying process.

Optionally, the specific process of obtaining the moisture content of the laundry in step S110 may be further described with reference to a schematic flow chart of an embodiment of obtaining the moisture content of the laundry in the method of the present invention shown in fig. 2, and may include: step S210 and step S220.

And step S210, acquiring the current change rate of the motor of the washing and drying integrated machine to be controlled.

More optionally, with reference to the schematic flow chart of an embodiment of the method of the present invention shown in fig. 3, which is used to obtain the current change rate of the motor of the washing and drying integrated machine to be controlled, further describing a specific process of obtaining the current change rate of the motor of the washing and drying integrated machine to be controlled in step S120, the method may include: step S310 to step S330.

And S310, controlling the forward and reverse rotation circulation operation of a motor of the washing and drying integrated machine to be controlled, and collecting the current of the motor according to a set collection frequency in the forward and reverse rotation circulation operation process of the motor.

Step S320, determining an average current of the motor in each operation period according to the collected multiple currents of the motor in each operation period.

Step S330, determining the change rate of the average current in the adjacent operation periods as the current change rate.

Therefore, the motor of the washing and drying integrated machine to be controlled is controlled to perform forward and reverse rotation circulation operation, and the change rate of the average value of the current of the motor in the forward and reverse rotation circulation operation process is determined as the current change rate required to be obtained, so that the determination of the current change rate is accurate and reliable.

And step S220, according to the corresponding relation between the set current change rate and the set water content range, determining the set water content range corresponding to the set current change rate which is the same as the current change rate in the corresponding relation as the water content range to which the water content belongs.

For example: through the change of motor current, judge the moisture content of clothing in a section of thick bamboo, and then control stoving temperature, reach best stoving dynamics, avoid unnecessary time and wasting of resources, also can reduce the damage that causes the clothing excessive drying simultaneously.

Therefore, the moisture content of the clothes in the inner drum of the washing and drying integrated machine to be controlled is determined according to the current change rate of the motor of the washing and drying integrated machine to be controlled, the determination mode is simple and convenient, and the determination result is accurate and reliable.

Specifically, the setting of the current change rate may include: a set wet current rate of change range, and/or a set dry current rate of change range.

Wherein, the lower limit of the wet current change rate range is larger than the upper limit of the dry current change rate range; and/or the set wet current change rate range and/or the set dry current change rate range can be adjusted up or down according to the set energy-saving requirement.

For example, the judgment value g for judging whether to dry can be determined according to the clothes state to be achieved, and the value is changed to finish drying when the clothes are dried and worn, or finish drying when the clothes are in an extremely dry state, for example, the water content of the judgment value g can be set to be + 3% when the clothes are dried and the motor current change rate △ Ig is correspondingly increased, and the water content of the judgment value g can be set to be-3% when the clothes are in the extremely dry state and the motor current change rate △ Ig is correspondingly decreased.

Specifically, the setting of the water content range may include: at least one set range of moisture content, and/or at least one set range of dry moisture content.

Wherein, more than one wet moisture content range can include: the moisture content is reduced in the range of the first to Nth wet moisture content in turn, and N is a natural number. The lower limit of the Nth wet water content range is larger than the upper limit of the dry water content range; and/or the set dry water content range can be increased or decreased according to the dry and wet state requirement of the user on the clothes.

Therefore, the moisture content of the clothes in the inner drum of the washing and drying integrated machine to be controlled is determined flexibly and accurately through the set current change rate and the set moisture content range in various forms.

More alternatively, the step S220 may determine a set moisture content range corresponding to a set current change rate that is the same as the current change rate in the correspondence relationship as the moisture content range to which the moisture content belongs, and may include at least one of the following moisture content determination cases.

First moisture cut determination scenario: and if the current change rate is larger than or equal to the upper limit of the set wet current change rate range, determining that the moisture content belongs to a set first wet moisture content range.

Second moisture determination scenario: and if the current change rate is larger than the lower limit of the wet current change rate range and smaller than the upper limit of the wet current change rate range, determining that the moisture content belongs to a set second wet moisture content range.

Third moisture determination scenario: and if the current change rate is less than or equal to the lower limit of the wet current change rate range, determining a third wet water content range to which the water content belongs.

Fourth moisture determination scenario: and if the current change rate is smaller than the lower limit of the wet current change rate range and is further smaller than or equal to the upper limit of the set dry current change rate range, or the current change rate belongs to the set dry current change rate range, determining that the water content belongs to the set dry water content range.

For example: it is determined whether the current change rate is greater than a lower limit of a set wet current change rate range and less than an upper limit of the wet current change rate range. And if the current change rate is larger than or equal to the upper limit of the set wet current change rate range, determining that the moisture content belongs to a set first wet moisture content range. Or, if the current change rate is greater than the lower limit of the wet current change rate range and less than the upper limit of the wet current change rate range, determining that the moisture content belongs to a set second wet moisture content range. Or, if the current change rate is less than or equal to the lower limit of the wet current change rate range, determining a third wet water content range to which the water content belongs.

Further optionally, in a case where the current change rate is less than or equal to a lower limit of the wet current change rate range, it is further determined whether the current change rate is less than or equal to an upper limit of the set dry current change rate range or belongs to the set wet current change rate range. And if the current change rate is smaller than the lower limit of the wet current change rate range and is further smaller than or equal to the upper limit of the set dry current change rate range, or the current change rate belongs to the set dry current change rate range, determining that the water content belongs to the set dry water content range.

For example: the positive and negative rotation of the motor is converted into a period, if the positive rotation is 15s and stops for 3s, the reverse rotation is 10s and stops for 2s, the frequency of the collected data is 1s, then the period is 30s, and the average value of 30 data collected in the 30s period is taken as i₁，i₂…i_n-1，i_nThe magnitude of the water content is judged according to the relation between the current change rate △ I and the water content η (as shown in figure 5), and then the drying temperature is automatically adjusted according to the magnitude of the water content according to the relation between the water content η and the drying temperature T (as shown in figure 6), so that the optimal drying strength is achieved (when the water content is larger, the drying temperature is set to be higher, the drying is accelerated, the drying time is shortened, when the water content is smaller, the drying temperature is reduced, the phenomenon that wrinkles are generated too fast in drying is avoided), and unnecessary time and resource waste are avoided.

Therefore, through various determination conditions of the water content, the corresponding water content can be determined according to different current change rates, and the determination of the water content is accurate and reliable.

At step S120, a drying temperature is determined according to the moisture content. For example: and determining the drying temperature required for drying the clothes according to the moisture content.

Optionally, the determining the drying temperature according to the moisture content in step S120 may include: and determining the set drying temperature corresponding to the set moisture content range with the same moisture content range as the moisture content range to which the moisture content belongs in the corresponding relation as the drying temperature according to the corresponding relation between the set moisture content range and the set drying temperature.

Therefore, the drying temperature corresponding to the corresponding water content is determined according to the corresponding relation between the set water content range and the set drying temperature, and the determination mode is simple, convenient and accurate.

Specifically, the water content may include: the water content of the clothes after the dehydration process is finished, or the water content of the clothes in the drying process.

Specifically, the setting of the drying temperature may include: a set running drying temperature, and/or a set stopping drying temperature (i.e., shutting down the drying process). The set operation drying temperature may include: and setting the first to Nth running drying temperatures, wherein N is a natural number.

Wherein the temperatures of the first to Nth drying operation temperatures are sequentially decreased; and/or the first to Nth drying operation temperatures can be adjusted to be larger or smaller according to the moisture content and the dry and wet state requirement of the user on the clothes.

For example, critical values △ Ic and △ Ib for judging the current change rate △ I of the motor can be properly adjusted according to whether energy is saved, so that the running time of a high drying temperature Tb and the running time of a low drying temperature Tc are both smaller than that of a medium drying temperature Ta, and energy consumption is prevented from being increased due to the fact that an electric heating device is operated for a long time at the high drying temperature and the low drying temperature Ta.

For example, the critical values of the water content rates of the high η b, the medium η a and the low η c can be properly adjusted according to the required drying speed, the adjustment of the critical values is to enable the clothes to be dried at the high drying temperature for a longer (short) time in order to enable the drying speed to be accelerated (slowed) but avoid the drying temperature to be too high when the water content rate is low and the drying to be too fast, otherwise, the clothes are easy to form wrinkles, if the quick drying is required, the high-temperature drying time is selected to be a little longer, the critical values for judging the water content rate and the motor current change rate are set, and the clothes are enabled to enter the high-temperature drying more quickly, if the default high-temperature drying is that the high-temperature drying is carried out when the water content rate is 60%, and the current change rate △ Ib is judged, if the quick drying is earlier than the default high-temperature drying, the high-temperature drying can be carried out by judging the current change rate 539ib 2 Ib 2 when the water content.

For example: the setting of the drying temperature (x ℃ is used for starting heating, and y ℃ is used for stopping heating) can be properly increased and reduced according to the water content and the desired drying speed. Such as: the water content is high, and the product is quickly dried, and the product is put through after being dried, the heating is started at 110 ℃, and the heating is stopped at 80 ℃. Such as: the water content is low, and if a user wants to reduce the damage of clothes during drying and slowly dry the clothes, the heating can be started at 50 ℃ and stopped at 30 ℃; therefore, the heating is started at x ℃, and the drying temperature can be automatically set according to the requirements of users when the heating is stopped at y ℃.

From this, through the moisture content of multiform, multiform set for stoving temperature, can satisfy the different stoving demands of different clothing materials, the flexibility is good, the reliability is high.

More alternatively, the set drying temperature corresponding to the set moisture content range in the correspondence relation, which is the same as the moisture content range to which the moisture content belongs, may be determined as the drying temperature, and at least one of the following drying temperature determination situations may be included.

First drying temperature determination case: and if the moisture content belongs to a set first wet moisture content range, determining that the drying temperature is a set first operation drying temperature.

Second drying temperature determination case: and if the moisture content belongs to a set second wet moisture content range, determining that the drying temperature is a set second operation drying temperature.

Third drying temperature determination case: and if the moisture content belongs to a third moisture content range, determining that the drying temperature is a set third operation drying temperature.

Fourth drying temperature determination scenario: and if the moisture content belongs to the set dry moisture content range, determining that the drying temperature is the set drying stopping temperature.

For example: in fig. 5 and 6, the moisture content is judged according to the motor current, and then the drying temperature data is adjusted, which can be seen in the following table:

rate of change of current	Water content ratio	Drying and heating temperature
			△Ib	ηb＞55％	High drying temperature Tb
△Ia	ηa＝25％～55％	Moderate drying temperature Ta
			△Ic	ηc＜25％	Low drying temperature Tc
△Ig	ηg＝-3％～+3％	Stopping drying and heating

For example, when the motor current change rate △ I is equal to (I)_n-1-i_n)/i_n-1When the water content is in the range of (△ Ic, △ Ib), it is judged from FIG. 5 that the water content is η a (example: η a-25% -55%),then automatically adjusting the drying temperature to be the medium drying temperature Ta according to the water content η a in FIG. 6 (for example, Ta can be set to 80 ℃ and electric heating is started at 60 ℃), otherwise, judging whether the motor current change rate △ I is greater than or equal to △ Ib, if △ I is greater than or equal to 827 Ib, judging that the water content is △ b (for example, △ b is greater than 55%), automatically adjusting the drying temperature to be the high drying temperature Tb according to the water content △ b (for example, Tb can be set to 110 ℃ and electric heating is started at 80 ℃), otherwise, explaining △ I is less than or equal to △ Ic, judging that the water content is △ c (for example, △ c is less than 25%), automatically adjusting the drying temperature to be the low drying temperature Tc according to the water content η c (for example, electric heating is turned off when the drying temperature is set to 50 ℃, electric heating is turned on at 30 ℃), as the drying progresses, the water content in the clothes is less and less, the water content in the clothes gradually decreases, the motor current change rate is slower and when the drying temperature reaches to reach △ g, the Ig 3 g, the temperature, otherwise, the water content is less than or less than 638 is decreased and the Ig 3 g is judged to be less than or less than 638, and less than or less than 638, and is judged according to be judged to be.

Therefore, through various determination conditions of the drying temperature, the corresponding drying temperature can be determined according to different water contents, and the determination of the drying temperature is accurate and reliable.

In step S130, the clothes are dried according to the drying temperature, so as to realize drying control when the clothes in the inner drum of the integrated washing and drying machine to be controlled are dried.

For example: the drying control method for automatically adjusting the drying temperature based on the current change of the motor solves the problems that the drying temperature cannot be automatically adjusted according to the moisture content, and the drying time and the energy consumption are influenced, can automatically adjust the drying temperature, shortens the drying time and reduces the water and electricity power consumption; the problem of when the moisture content is less, because the stoving temperature is too high, dry the too fast wrinkle that produces is solved, can reduce the clothing and cross the stoving and cause irreversible damage to the fabric, form the wrinkle when can also avoiding the clothing to dry.

Therefore, the corresponding drying temperature is determined according to the moisture content of the clothes in the inner drum of the washing and drying integrated machine to be controlled, and then the clothes are dried according to the drying temperature, so that the problems that the drying temperature is too low, the drying time is prolonged, the energy consumption is increased and the waiting time is too long when a user needs to dry quickly are solved; on the other hand can avoid the stoving high temperature and lead to the clothing to appear fold, harm the appearance of clothing material scheduling problem to, make the stoving effect greatly promote.

Through a large amount of experimental verifications, adopt the technical scheme of this embodiment, through judging the moisture content of clothing in a section of thick bamboo, and then according to moisture content control stoving temperature, can solve the size that can't pass through the size automatically regulated stoving temperature of moisture content, influence the problem of stoving time and energy consumption, can shorten stoving time, reduce the energy consumption.

Since the processes and functions implemented by the apparatus of this embodiment substantially correspond to the embodiments, principles and examples of the method shown in fig. 1 to 3, the description of this embodiment is not detailed, and reference may be made to the related descriptions in the foregoing embodiments, which are not repeated herein.

Through a large number of tests, the technical scheme of the invention is adopted, and the drying temperature is controlled according to the moisture content by judging the moisture content of the clothes in the drum, so that the problem that when the moisture content is smaller, wrinkles are generated due to overhigh drying temperature and too fast drying can be solved, the wrinkles can be reduced, and the loss of the clothes is reduced.

According to the embodiment of the invention, the washing and drying integrated machine corresponding to the drying control device is also provided. The washing and drying all-in-one machine can comprise: the drying control device is described above.

In an optional embodiment, the scheme of the invention provides a drying control method for automatically adjusting the drying temperature based on the current change of a motor, solves the problem that the drying time and energy consumption are influenced because the drying temperature cannot be automatically adjusted according to the moisture content, can automatically adjust the drying temperature, shortens the drying time and reduces the water and electricity power consumption; the problem of when the moisture content is less, because the stoving temperature is too high, dry the too fast wrinkle that produces is solved, can reduce the clothing and cross the stoving and cause irreversible damage to the fabric, form the wrinkle when can also avoiding the clothing to dry.

In an optional example, according to the scheme of the invention, the moisture content of the clothes in the drum is judged through the change of the current of the motor, so that the drying temperature is controlled, the optimal drying force is achieved, unnecessary time and resource waste is avoided, and meanwhile, the damage to the excessive drying of the clothes can be reduced.

In an alternative embodiment, a specific implementation process of the scheme of the present invention can be exemplarily described with reference to the examples shown in fig. 5 to 7.

In fig. 5 and 6, the moisture content is judged according to the motor current, and then the drying temperature data is adjusted, which can be seen in the following table:

When a drying program runs in the washing and drying integrated machine, firstly weighing is carried out, the current of the motor is detected, the forward and reverse rotation of the motor is converted into a period, if the forward rotation is 15s and stops for 3s, the reverse rotation is 10s and stops for 2s, the frequency of collected data is 1s, the period is 30s, and the average value of 30 data collected in the 30s period is recorded as i₁，i₂…i_n-1，i_nThe magnitude of the water content is judged according to the relation between the current change rate △ I and the water content η (as shown in figure 5), and then the drying temperature is automatically adjusted according to the magnitude of the water content according to the relation between the water content η and the drying temperature T (as shown in figure 6), so that the optimal drying strength is achieved (when the water content is larger, the drying temperature is set to be higher, the drying is accelerated, the drying time is shortened, when the water content is smaller, the drying temperature is reduced, the phenomenon that wrinkles are generated too fast in drying is avoided), and unnecessary time and resource waste are avoided.

For example: weighing is to detect the mass of clothes to be dried in the drum, so as to match the predicted drying time of the drying program, if weighing 5kg, the predicted residual drying time is displayed at 2: 50; weighing 3kg, and displaying the predicted drying time to be 2: 30; the weighing has little influence on judging the current change rate and further judging the water content and adjusting the drying temperature in the drying process.

When the motor current change rate △ I ═ I (I)_n-1-i_n)/i_n-1When the moisture content is in the range of (△ Ic, △ Ib), the water content is judged to be △ 0a (example: △ 1a is 25% -55%) according to fig. 5, then the water content is automatically adjusted to be the intermediate drying temperature Ta (example: Ta can be set to 80 ℃ and electric heating is turned on when 60 ℃) according to △ 4a of fig. 6, otherwise, whether the motor current change rate △ 2I is judged to be more than or equal to △ 3Ib, when △ I is more than or equal to △ Ib, the water content is judged to be △ 5b (example: η b > 55%), the drying temperature is automatically adjusted to be the high drying temperature Tb (example: Tb can be set to 110 ℃ and electric heating is turned on when 80 ℃) according to η b, otherwise, △ I is not more than △ Ic, and the water content is judged to be η c (example: η c < 25, 25%) (example: water content is judged to be η c),the drying temperature is automatically adjusted to be the low drying temperature Tc according to the water content η c (for example, the electric heating is turned off when the drying temperature is set to be 50 ℃, and the electric heating is turned on when the drying temperature is 30 ℃), as the drying progresses, the water content in the clothes is gradually reduced, the change rate of the motor current is gradually reduced, and the change is basically not changed when the drying is reached, when △ I is less than or equal to △ Ig, the water content is η g (for example, -3% < η g < + 3%), the water content is reduced to be basically not changed, and the electric heating is turned off as a judgment basis, the temperature is reduced, the program is ended, otherwise, the Tc temperature is continuously carried out for drying until △ I is less than or equal to △ Ig.

In an alternative embodiment, the determination value g for determining whether to dry may be determined according to the clothes state desired to be achieved, and by changing this value, the drying may be finished when the clothes is finished, i.e. worn, or when the clothes is in an extremely dry state.

For example, the water content of the judgment value g can be set to be + 3% after the clothes are dried and the motor current change rate △ Ig is correspondingly increased, and the water content of the judgment value g can be set to be-3% in an extremely dry state, and the motor current change rate △ Ig is correspondingly reduced.

In an alternative embodiment, in the solution of the present invention, the threshold values △ Ic and △ Ib for determining the magnitude of the current change rate △ I of the motor can be properly adjusted according to whether energy is saved, so as to ensure that the operation time of the high drying temperature Tb and the operation time of the low drying temperature Tc are both less than the operation time of the medium drying temperature Ta, and avoid the increase of energy consumption caused by long-time operation of the electric heating device at the high drying temperature and the low drying temperature.

Generally, the electric heating or heat pump power consumption is less than that of high-temperature drying during low-temperature drying, so that the high-temperature drying time is shortened in energy-saving regulation, the water content of high-temperature drying regulation is increased, and the corresponding motor current change rate is increased.

If the moisture content is judged to be 60% originally, high-temperature drying is carried out when the current change rate is judged to be △ Ib, and if the energy-saving regulation is carried out, the current change rate is judged to be △ Ib when the moisture content is judged to be 70%, high-temperature drying is carried out, and the condition that the moisture content between 60% and 70% is changed from high-temperature drying to medium-temperature drying after regulation is shown, so that energy is saved.

In an alternative embodiment, the critical values of the water content ratios η b, η a and η c may be adjusted according to the desired drying speed, and the critical values are adjusted to enter the high drying temperature stage more quickly (slowly) and end the high drying temperature stage more slowly (quickly) during drying, so that the clothes can be dried at the high drying temperature for a longer (short) time, and the drying speed is increased (slowed) but the drying temperature is prevented from being too high when the water content ratio is low, and the drying is too fast, which may cause wrinkles to form on the clothes.

Such as: and if the fast drying is required, selecting a long high-temperature drying time, and then setting critical values for judging the water content and the motor current change rate to enable the high-temperature drying to be carried out more quickly.

For example, the high-temperature drying is performed by default when the moisture content is 60% and the current change rate is determined to be △ Ib, the high-temperature drying is performed earlier than the default when the fast drying is performed, and the high-temperature drying is performed by changing the moisture content to be 40% and determining the current change rate to be △ Ib, so that the high-temperature drying is performed earlier.

In an alternative embodiment, the setting of the drying temperature (x ℃ C. on heating, y ℃ C. off heating) in the solution of the present invention can be increased or decreased according to the moisture content and the desired drying speed.

Such as: the water content is high, and the product is quickly dried, and the product is put through after being dried, the heating is started at 110 ℃, and the heating is stopped at 80 ℃.

Such as: the water content is low, and if a user wants to reduce the damage of clothes during drying and slowly dry the clothes, the heating can be started at 50 ℃ and stopped at 30 ℃; therefore, the heating is started at x ℃, and the drying temperature can be automatically set according to the requirements of users when the heating is stopped at y ℃.

In the above embodiments, the description of the meaning of each symbol can be found in the following description:

△ I current change rate, △ Ia, △ Ib, △ Ic and △ Ig current change rates corresponding to points a, b, c and g in FIG. 5, I₁，i₂…i_n-1，i_nThe method comprises the steps of collecting current average values in the positive and negative rotation periods of a motor, η moisture content, η a, η b, η c and η g moisture content corresponding to points a, b, c and g in the figures 5 and 6 respectively, T drying temperature, and Ta, Tb and Tc drying temperatures corresponding to points a, b and c in the figure 6 respectively.
