[0074] The following will be combined with the drawings in this application to clearly and completely describe the technical solutions in this application. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0075] In one embodiment of the present application, the drying process can be roughly divided into an initial stage, an intermediate stage, a fast drying stage, and a cooling stage. In the initial stage, the temperature in the drying barrel rises significantly, and the heat of the heating tube is mainly used to increase the temperature of the load and water. At this time, the water vapor content in the air is relatively low, the condensation efficiency is low, and the air volume demand is low. In the intermediate stage, the temperature in the drying barrel rises to a certain value and remains stable. At this time, the load is also maintained at a stable temperature. Therefore, the heat of the heating tube is mainly used for the latent heat of vaporization of the water in the load. Therefore, the water vapor content in the air is sufficient to achieve sufficient heat exchange with the condensed water, the condensation efficiency is high, and the air volume demand is high. In the fast drying stage, the water content in the load is low, and the water vapor content in the air is reduced. Therefore, the temperature in the drying barrel gradually decreases, but the heat of the heating tube causes the temperature of the load to rise rapidly. At this time, the condensation efficiency is low and the air volume demand is low. In the cooling stage, the heating tube is turned off, and the temperature in the drying barrel decreases. In order to quickly cool down the load, the air volume demand is high.

[0076] In the stage where the air volume demand is low, if the fan is still operated at the speed required when the heat exchange demand is maximum to generate air volume, it will cause waste of air volume and electric energy. In order to overcome this technical problem, an embodiment of the present application flexibly adjusts the fan speed during the drying process, and can reduce the fan speed in the stage where the air volume demand is low, thereby achieving energy saving while ensuring the drying effect.

[0077] In one embodiment, Figure 1 As shown, a method for adjusting the speed of a fan is provided. Although a logical order is shown in the step diagram, in some cases, the steps shown or described may be performed in an order different from that shown in the figure. Specifically, the method for adjusting the speed of a fan may be applied to a drying device, wherein the drying device may include but is not limited to one or more of a drying machine, a washer-dryer, and an electronic device with a drying function.

[0078] The drying device includes a heating device and a fan. The heating device can heat the objects to be dried in the drying device to generate water vapor, and the fan can generate wind to take away the water vapor to achieve drying of the objects to be dried. It can be understood that the objects to be dried in the drying device, and the water contained and / or not contained in the objects to be dried, are the load of the drying device.

[0079] It should be noted that the order of description of the following embodiments is not intended to limit the priority order of the embodiments.

[0080] according to Figure 1 The fan speed adjustment method shown in the figure includes at least steps S110 to S140, which are described in detail as follows:

[0081] In step S110, the current temperature in the drying barrel is obtained.

[0082] The drying barrel is a container in the drying equipment for accommodating objects to be dried. The objects to be dried may include, but are not limited to, one or more of clothes, vegetables, fruits, or seeds. The drying equipment can be used to remove moisture from the objects to be dried; for example, the drying equipment can dry wet clothes into dry clothes, dry vegetables into dried vegetables, dry fruits into dried fruits, and remove moisture from seeds. The shape of the drying barrel can be cylindrical, cubic, twisted prism, or other shapes, which is not limited in the embodiments of the present application.

[0083] The current temperature in the drying barrel may refer to the current temperature at a fixed position in the drying barrel. Alternatively, the current temperature in the drying barrel may be the current temperature at the bottom of the drying barrel. A temperature sensor may be used to detect the current temperature in the drying barrel. The temperature sensor may be a negative temperature coefficient thermistor (NTC) of a water heating tube.

[0084] After the current temperature in the drying barrel is detected, the current temperature in the drying barrel can be transmitted to the drying device, and the drying device can store, calculate and analyze the received current temperature in the drying barrel. Optionally, the drying device can include a calculation module and a storage module, the storage module can store a temperature sequence during the drying process, the temperature sequence including the temperature in the drying barrel at multiple moments during the drying process; the calculation module can obtain the temperature in the drying barrel at multiple moments from the storage module or the temperature sensor, so as to calculate and analyze the temperature in the drying barrel.

[0085] In step S120 , a plurality of temperature ranges are acquired.

[0086] The multiple temperature ranges are used to divide the drying process into multiple stages. According to the temperature range of the current temperature in the drying barrel, it can be roughly determined which stage the drying process is in, thereby determining which fan speed calculation method to use.

[0087] Figure 2 : is a curve diagram of temperature, humidity and wind speed during the drying process provided by an embodiment of the present application. Figure 2 It can be seen that the temperature in the drying barrel has a temperature rising process and a temperature falling process. Generally speaking, the temperature in the drying barrel rises from normal temperature / room temperature to the first temperature and maintains at the first temperature for a period of time, and then starts to drop. During the temperature drop process, the temperature in the drying barrel will drop to the third temperature and the second temperature in turn. The first temperature is the highest set temperature, the second temperature is used to determine whether to dry, and the third temperature is used to determine whether to reduce the fan speed. After the temperature in the drying barrel drops to the second temperature, it is considered that the object to be dried is dried, so the object to be dried can be quickly cooled down.

[0088] In the initial stage when the temperature in the drying barrel rises from normal temperature / room temperature to the first temperature, and in the fast drying stage when the temperature in the drying barrel drops from the third temperature to the second temperature, the air volume demand is low and the fan speed is significantly reduced. In the middle stage when the temperature in the drying barrel drops from the first temperature to the third temperature, and in the cooling stage when the temperature in the drying barrel starts to drop from the second temperature, the air volume demand is high.

[0089] Therefore, multiple temperature ranges can be determined based on the first temperature, the second temperature, and the third temperature. Optionally, a temperature range less than or equal to the first temperature can be determined as the first temperature range; a temperature range less than or equal to the first temperature and greater than the third temperature can be determined as the second temperature range; a temperature range less than or equal to the third temperature range and greater than or equal to the second temperature can be determined as the third temperature range; and a temperature range less than the second temperature can be determined as the fourth temperature range.

[0090] In step S130, a method for calculating a fan speed corresponding to the current temperature is determined according to the temperature range in which the current temperature is located.

[0091] The fan speed corresponding to the initial stage and the fast drying stage is lower than the fan speed corresponding to the intermediate stage and the cooling stage. However, because the temperature in the drying barrel has a temperature rise process and a temperature drop process, a temperature may be in the first temperature range and the second temperature range at the same time. For example, when the first temperature is 50°C and the third temperature is 45°C, the first temperature range is (0,50] and the second temperature range is (45,50], then 47°C is in both the first temperature range and the second temperature range.

[0092] Therefore, in order to accurately determine the stage corresponding to the current temperature, the current temperature can be accurately determined according to the drying time and / or the change state of the current temperature, combined with the temperature range of the current temperature, to determine which stage the current temperature is in, and then accurately determine the fan speed calculation method corresponding to the current temperature. The following text will detail the method for determining the drying stage corresponding to the current temperature according to the drying time and the temperature range of the current temperature, and the method for determining the drying stage corresponding to the current temperature according to the change state of the current temperature and the temperature range of the current temperature.

[0093] In step S140, the current fan speed is determined according to the fan speed calculation method.

[0094] In step S150, the fan speed corresponding to the drying barrel is adjusted according to the current fan speed.

[0095] According to the fan speed calculation method corresponding to the determined current temperature, the current fan speed can be calculated, so that the fan speed corresponding to the drying barrel can be adjusted to the current fan speed.

[0096] In the related art, the fan is operated at the maximum fan speed during the entire drying process, which will cause energy waste in the stage with low air volume demand. An embodiment of the present application divides the temperature range and determines the current drying stage according to the temperature range in which the current temperature in the drying barrel is located, and sets corresponding fan speed calculation methods for different drying stages to calculate the fan speed that meets the current drying stage, thereby flexibly adjusting the fan speed and saving energy.

[0097] By adopting the technical solution of the embodiment of the present application, different fan speed calculation methods can be determined according to the temperature range of the current temperature in the drying barrel, so that the current fan speed can be calculated according to the different fan speed calculation methods, and then the fan speed corresponding to the drying barrel can be adjusted to the current fan speed. In this way, the fan speed can be flexibly adjusted, and the waste of electric energy caused by running at the maximum wind speed during the entire drying process can be avoided, so as to save electric energy while ensuring the drying effect.

[0098] Based on the above technical solution, as an embodiment, obtaining multiple temperature ranges may include: obtaining the load weight in the drying barrel; determining the first temperature, the second temperature and the temperature difference corresponding to the load weight according to the load weight; the first temperature is the highest set temperature; the second temperature is used to determine whether to dry; the sum of the second temperature and the temperature difference is determined as the third temperature; the third temperature is used to determine whether to reduce the fan speed; and the multiple temperature ranges are determined according to the first temperature, the second temperature and the third temperature.

[0099] When the load weight in the drying barrel is different, the first temperature, the second temperature and the temperature difference are also different. The sum of the second temperature and the temperature difference is the third temperature. Therefore, when the load weight in the drying barrel is different, the first temperature, the second temperature and the third temperature are also different.

[0100] The corresponding relationship between the load weight, the first temperature, the second temperature and the temperature difference can be pre-built based on experiments or big data, and the corresponding relationship can be saved in the drying device. When drying is required, the load weight in the drying barrel is first detected, and then the pre-built corresponding relationship is queried to determine the first temperature, the second temperature and the temperature difference corresponding to the load weight. The third temperature is obtained based on the second temperature and the temperature difference. The third temperature is greater than the second temperature.

[0101] In the initial stage, the temperature in the drying barrel rises significantly until it reaches the first temperature; in the middle stage, the temperature in the drying barrel rises to the first temperature and maintains it, and even if it drops, the drop is small and drops to the third temperature; in the fast drying stage, the temperature in the drying barrel gradually drops from the third temperature to the second temperature; in the cooling stage, the temperature in the drying barrel drops and drops significantly from the second temperature.

[0102] Therefore, a temperature range less than or equal to the first temperature can be determined as the first temperature range; a temperature range less than or equal to the first temperature and greater than the third temperature can be determined as the second temperature range; a temperature range less than or equal to the third temperature range and greater than or equal to the second temperature can be determined as the third temperature range; and a temperature range less than the second temperature can be determined as the fourth temperature range.

[0103] By adopting the technical solution of the embodiment of the present application, the corresponding first temperature, second temperature and third temperature are determined according to the load weight, which can achieve more precise control compared to fixed first temperature, second temperature and third temperature; multiple temperature ranges are determined according to the first temperature, second temperature and third temperature, and different drying stages can be distinguished, so as to accurately determine the fan speed calculation method, flexibly adjust the fan speed, and save electricity.

[0104] On the basis of the above technical solution, as an embodiment, the method for calculating the fan speed corresponding to the current temperature according to the temperature range in which the current temperature is located may include: obtaining the drying time; and determining the method for calculating the fan speed corresponding to the current temperature according to the drying time and the temperature range in which the current temperature is located.

[0105] The drying time represents the time from the start of the drying process to the time when the current temperature is determined. Because the initial stage is an earlier procedure in the drying process, the temperature in the initial stage corresponds to a shorter drying time.

[0106] A drying time threshold may be obtained, and the drying time threshold is used to determine whether the drying stage is in the initial stage. The drying time threshold may be a value that changes according to the load weight. The corresponding relationship between the load weight and the drying time threshold may be obtained through experiments or big data. When the load weight is obtained, the corresponding relationship is queried according to the load weight to obtain the drying time threshold corresponding to the load weight.

[0107] When the drying time is less than the drying time threshold and the current temperature is in the first temperature range, it indicates that the current drying stage is in the initial stage. When the drying time is not less than the drying time threshold or the current temperature is not in the first temperature range, it indicates that the current drying stage is not in the initial stage.

[0108] By adopting the technical solution of the embodiment of the present application, the current drying stage can be accurately determined according to the drying time and the temperature range of the current temperature, thereby accurately determining the fan speed calculation method corresponding to the current temperature, realizing flexible adjustment of the fan speed and saving electricity.

[0109] On the basis of the above technical solution, as an embodiment, the method for calculating the fan speed corresponding to the current temperature according to the temperature range in which the current temperature is located may include: obtaining the changing state of the current temperature; the changing state includes a temperature rising state and a temperature falling state; determining the method for calculating the fan speed corresponding to the current temperature according to the changing state and the temperature range in which the current temperature is located.

[0110] The change state of the current temperature indicates whether the current temperature is in a temperature rising process or a temperature falling process. When the current temperature is in a temperature rising state, it indicates that the current temperature is in a temperature rising process; when the current temperature is in a temperature falling state, it indicates that the current temperature is in a temperature falling process and / or in a process of maintaining the current temperature.

[0111] Optionally, when the current temperature in the drying barrel is a temperature in the process of rising from normal temperature / room temperature to the first temperature, the current temperature change state is a temperature rising state; when the current temperature in the drying barrel is a temperature in the process of maintaining the first temperature and / or starting to drop from the first temperature, the current temperature change state is a temperature dropping state.

[0112] When the current temperature is in the first temperature range and the change state is a temperature rising state, it is determined that the drying stage is in the initial stage, and the fan speed calculation method corresponding to the current temperature at this time is the first fan speed calculation method.

[0113] When the current temperature is in the second temperature range and the change state is a temperature drop state, it is determined that the drying stage is in the middle stage, and the fan speed calculation method corresponding to the current temperature at this time is the second fan speed calculation method.

[0114] When the current temperature is in the third temperature range and the change state is a temperature drop state, it is determined that the drying stage is in the fast drying stage, and the fan speed calculation method corresponding to the current temperature at this time is the third fan speed calculation method.

[0115] When the current temperature is in the fourth temperature range and the change state is a temperature drop state, it is determined that the drying stage is in the cooling stage, and the fan speed calculation method corresponding to the current temperature at this time is the fourth fan speed calculation method.

[0116] By adopting the technical solution of the embodiment of the present application, the current drying stage can be accurately determined according to the changing state of the current temperature and the temperature range in which the current temperature is located, thereby accurately determining the fan speed calculation method corresponding to the current temperature, realizing flexible adjustment of the fan speed and saving electricity.

[0117] On the basis of the above technical solution, as an embodiment, the fan speed calculation method corresponding to the current temperature is determined according to the change state and the temperature range in which the current temperature is located, and may include: when the current temperature is in a first temperature range and the change state is a temperature rising state, determining that the fan speed calculation method corresponding to the current temperature is a first fan speed calculation method, and the first fan speed calculation method is as follows:

[0118] When 0<T≤T1, N=a1*x+b1;

[0119] Wherein, 0<T≤T1 represents the first temperature range, T is the current temperature, T1 is the first temperature, N is the current fan speed, x is the fan speed adjustment time, and a1 and b1 are preset parameters. a1 and b1 can be determined based on experiments or big data. a1 is a positive number. N is not greater than the maximum fan speed that the fan can reach. When the calculated N is greater than the maximum fan speed that the fan can reach, N is taken as the maximum fan speed.

[0120] The fan speed adjustment time refers to the time from the start of fan speed adjustment to the current time. For example, if a1 and b1 are set to 2 and 10 respectively, and the fan speed is adjusted from the 0th moment, the fan speed at the 5th moment is 2*5+10=20.

[0121] When the current temperature is in the first temperature range and the change state is a temperature rise state, it is in the initial stage. The heat of the heating pipe is mainly used for the load and water temperature rise. At this time, the water vapor content in the air is small, the condensation efficiency is low, and the air volume demand is low. Therefore, the fan speed can be set to increase gradually and not exceed the maximum fan speed.

[0122] By adopting the technical solution of the embodiment of the present application, the calculated fan speed is less than the maximum fan speed, so electric energy can be saved; because when the current temperature is in the first temperature range and the changing state is a temperature rising state, the required air volume is less, and therefore the current fan speed is determined by the first fan speed calculation method, which can save electric energy while ensuring the drying effect.

[0123] On the basis of the above technical solution, as an embodiment, the fan speed calculation method corresponding to the current temperature is determined according to the change state and the temperature range in which the current temperature is located, including: when the current temperature is in the second temperature range and the change state is a temperature drop state, the fan speed calculation method corresponding to the current temperature is determined to be a second fan speed calculation method, and the second fan speed calculation method is as follows:

[0124] When T1≥T>T2+ΔT, N=M;

[0125] Wherein, T1≥T>T2+ΔT represents the second temperature range, T is the current temperature, T1 is the first temperature, T2 is the second temperature, ΔT is the temperature difference, N is the current fan speed, and M is the maximum fan speed. T2+ΔT is the third temperature. The maximum fan speed can be the maximum fan speed that the fan can reach, or it can be the maximum fan speed determined according to the load.

[0126] When the current temperature is in the second temperature range and the change state is a temperature drop state, it is in the intermediate stage, in which the temperature in the drying barrel rises to a certain value and remains stable, and the load is also maintained at a stable temperature. Therefore, the heat of the heating tube is mainly used for the latent heat of vaporization of water in the load. Therefore, the water vapor content in the air is sufficient, and sufficient heat exchange with condensed water can be achieved, the condensation efficiency is high, and the air volume demand is high. In order to provide sufficient air volume, the current fan speed can be determined to be the maximum fan speed.

[0127] By adopting the technical solution of the embodiment of the present application and providing the maximum fan speed for the intermediate stage, sufficient air volume can be provided, thereby achieving sufficient heat exchange between water vapor and condensed water and improving drying efficiency.

[0128] On the basis of the above technical solution, as an embodiment, the fan speed calculation method corresponding to the current temperature is determined according to the change state and the temperature range in which the current temperature is located, and may include: when the current temperature is in a third temperature range and the change state is a temperature drop state, determining that the fan speed calculation method corresponding to the current temperature is a third fan speed calculation method, and the third fan speed calculation method is as follows:

[0129] When T2+ΔT≥T≥T2, N=a2*x+b2;

[0130] Wherein, T2+ΔT≥T≥T2 represents the third temperature range, T is the current temperature, T2 is the second temperature, ΔT is the temperature difference, N is the current fan speed, x is the fan speed adjustment time, and a2 and b2 are preset parameters. a2 and b2 can be determined based on experiments or big data. a2 is a negative number. T2+ΔT is the third temperature. N is not greater than the maximum fan speed that the fan can reach. When the calculated N is greater than the maximum fan speed that the fan can reach, N is taken as the maximum fan speed.

[0131] The fan speed adjustment time refers to the time from the start of adjusting the fan speed to the current time. For example, if a2 and b2 are set to -2 and 100 respectively, and the fan speed is adjusted from the 0th moment, the fan speed at the 6th moment is -2*6+100=88.

[0132] When the current temperature is in the third temperature range and the change state is a temperature drop state, it is in the fast drying stage. In this stage, the water content in the load is low and the water vapor content in the air is reduced. Therefore, the temperature in the drying barrel gradually decreases, but the heat of the heating tube causes the temperature of the load to rise rapidly. At this time, the condensation efficiency is low and the air volume demand is low. Therefore, the fan speed can be set to gradually decrease and not be greater than the maximum fan speed.

[0133] By adopting the technical solution of the embodiment of the present application, the calculated fan speed is less than the maximum fan speed, so electric energy can be saved; because when the current temperature is in the third temperature range and the changing state is a temperature dropping state, the required air volume is less, and therefore the current fan speed is determined by the third fan speed calculation method, which can save electric energy while ensuring the drying effect.

[0134] On the basis of the above technical solution, as an embodiment, the fan speed calculation method corresponding to the current temperature is determined according to the change state and the temperature range in which the current temperature is located, and may include: when the current temperature is in a fourth temperature range and the change state is a temperature drop state, determining that the fan speed calculation method corresponding to the current temperature is a fourth fan speed calculation method, and the fourth fan speed calculation method is as follows:

[0135] When T2>T, N=M;

[0136] Among them, T2>T represents the fourth temperature range, T is the current temperature, T2 is the second temperature, N is the current fan speed, and M is the maximum fan speed.

[0137] When the current temperature is in the fourth temperature range and the change state is a temperature drop state, it is in a cooling stage, in which the heating tube is turned off, the temperature in the drying barrel is reduced, and the air volume requirement is high to quickly cool the load. In order to provide sufficient air volume, the current fan speed can be determined to be the maximum fan speed.

[0138] By adopting the technical solution of the embodiment of the present application, by providing the maximum fan speed for the cooling stage, sufficient air volume can be provided, thereby achieving rapid cooling of the load and improving drying efficiency.

[0139] Figure 3 It is a flow chart of the fan speed adjustment method provided in one embodiment of the present application. When the drying program is started, the fan and the heating tube can be turned on, and the fan speed is N=a1*x+b1. After the fan speed reaches the maximum fan speed, the maximum fan speed is maintained, and the current temperature in the drying barrel is monitored to see if it drops to the third temperature. When the current temperature has not dropped to the third temperature, the maximum fan speed continues to be maintained. After the current temperature drops to the third temperature, the fan speed is adjusted to N=a2*x+b2. Detect whether the current temperature in the drying barrel has dropped to the second temperature. When the current temperature has not dropped to the second temperature, continue to operate at a fan speed of N=a2*x+b2. After the current temperature drops to the second temperature, adjust the fan speed to the maximum fan speed until the drying is completed.

[0140] By adopting the technical solution of the embodiment of the present application, flexible adjustment of the fan speed is achieved, which can avoid the waste of electricity caused by running at the maximum wind speed during the entire drying process, and save electricity while ensuring the drying effect.
