[0059] The shape and size of the box body 1 in the embodiment of this application are not specifically limited and can be designed according to actual needs. As Figure 2As shown in the figure, a storage rack 5 is provided in the enclosed chamber. The wet objects to be dried are hung on the storage rack 5, and the box body 1 is located below the wet objects to be dried. Among them, a weight sensor can be arranged at the bottom of the storage rack 5 to monitor the weight of the wet objects to be dried in real time. An air inlet is provided at the top of the box body 1, and a fan 2 is provided below the air inlet. The air in the enclosed chamber enters the box body 1 through the air inlet under the action of the fan 2 and then flows into the storage container 3.

The specific control method will be further introduced in the method embodiment below.

[0060] Based on the above intelligent drying system, the air circulation direction is as follows: The humid air in the closed chamber enters the box body 1 through the air inlet of the box body 1 under the action of the fan 2, then flows into the storage container 3 for drying. The dried air is discharged from the box body 1 through the electric louver 4 below the storage container 3 under the continuous push of the fan 2 and enters the closed chamber, contacts the wet object to be dried, takes away the moisture in the wet object, and achieves the purpose of drying the wet object. The humid air then re-enters the box body 1 for drying, repeating the cycle, and drying the wet object using the humidity difference. Among them, the wet object can be clothes, bedding, etc. The fan 2 is responsible for generating air flow, accelerating air circulation, and improving the dehumidification efficiency. Its rotation speed can be adjusted according to the instructions of the controller to meet different dehumidification requirements. The electric louver 4 can optimize the air flow direction, so that the dried air is discharged obliquely upward, forming a conical drying area in the closed chamber, increasing the contact area with the wet object, promoting the transfer of moisture under the humidity gradient difference, and achieving efficient drying. The ventilation adjustment device is used to control the opening and closing ratio of the ventilation holes of the storage container 3, thereby controlling the moisture absorption effect.

[0061] The intelligent drying system provided by the embodiments of the present application includes: a box body 1, a fan 2, a storage container 3, a ventilation adjustment device, an electric louver 4, a weight sensor, a temperature and humidity sensor, and a controller; the box body 1 is placed below the wet object to be dried in the closed chamber. The top of the box body 1 is provided with an air inlet, the fan 2 is arranged below the air inlet, the storage container 3 is located below the fan 2 and is used for storing desiccant.

The weight sensor is used to monitor the weight of the wet object to be dried in real time. The temperature and humidity sensor is used to monitor the ambient temperature and humidity in the closed chamber in real time. The controller is respectively connected to the fan 2, the ventilation adjustment device, the electric louver 4, the weight sensor, and the temperature and humidity sensor. The fan 2 introduces the ambient air in the closed chamber into the box body 1, dries it through the desiccant in the storage container 3, and discharges it through the electric louver 4 to form an air circulation; the dried air enters the closed chamber, forms a large humidity difference with the wet object to be dried, promotes the evaporation of the moisture in the wet object, and realizes drying.

The rotating shaft of the motor 201 extends out of the installation box 10 and is connected to the blades 202 of the fan 2. The blades 202 of the fan 2 are located between the first sieve plate 8 and the second sieve plate 9. Driven by the motor 201, the blades 202 suck the air filtered by the first sieve plate 8 and the second sieve plate 9 and convey it downward to the storage container 3.

[0064] Based on the above embodiments, a partition plate 11 is provided inside the box body 1. The partition plate 11 is located below the second sieve plate 9. The storage container 3 is located between the partition plate 11 and the second sieve plate 9. The storage container 3 includes a box body and a cover body 301.

The cover body 301 is provided with a plurality of first ventilation holes 302. The bottom surface of the box body is provided with a plurality of second ventilation holes.

[0066] Based on the above embodiment, the ventilation adjustment device of the embodiment of the present application includes a first driving motor and a sliding plate 14 connected to the first driving motor. The sliding plate 14 is located above the cover body 301. A plurality of third ventilation holes 1401 corresponding to the first ventilation holes 302 one by one are provided on the sliding plate 14. The first driving motor is used to drive the sliding plate 14 to slide relative to the cover body 301 so that the first ventilation holes 302 and the third ventilation holes 1401 are aligned or staggered.

[0067] In the embodiment of the present application, the design of the sliding plate 14 enables the adjustment of the opening and closing ratio of the ventilation holes to be very flexible, and the ventilation volume can be adjusted at any time according to actual needs to adapt to different drying scenarios and requirements. When it is necessary to increase the ventilation volume, the first driving motor drives the sliding plate 14 to slide so that the first ventilation holes 302 and the third ventilation holes 1401 are aligned, and air can enter the storage container 3 through the ventilation holes; when it is necessary to reduce the ventilation volume, the first driving motor drives the sliding plate 14 to slide so that the first ventilation holes 302 and the third ventilation holes 1401 are partially or completely staggered, thereby reducing or preventing air from entering the storage container 3. Figure 5 is a schematic diagram of a cover body and a sliding plate provided by the embodiment of the present application, Figure 5The first ventilation hole 302 and the third ventilation hole 1401 in it are partially staggered. The controller automatically adjusts the movement of the first driving motor according to the information fed back by the temperature and humidity sensor and the weight sensor, thereby controlling the sliding position of the sliding plate 14 and realizing the adjustment of the opening and closing ratio of the ventilation holes. For example, when the environmental humidity is high, the controller can increase the ventilation volume to accelerate the drying speed; when the environmental humidity is low, the controller can reduce the ventilation volume to avoid over-drying.

Among them, the opening angle is the included angle between the strip plate and the side wall of the box body 1.

[0070] Based on the above embodiments, Figure 7 The structure diagram of a collection bottle provided by an embodiment of the present application is shown in Figure 7 and Figure 1 As shown, the embodiment of the present application further includes a collection bottle 15. The bottle mouth of the collection bottle 15 is detachably connected to the ventilation port 13. An open structure is provided in a circle on the side wall of the collection bottle 15, and a plurality of partition pieces 1501 are provided at intervals in the open structure.

[0071] In the embodiments of the present application, the bottle mouth of the collection bottle 15 and the ventilation port 13 can be connected by means of screw connection, snap connection or plug connection, etc. The bottle mouth of the collection bottle 15 and the ventilation port 13 of the partition plate 11 are detachably connected, which is convenient for users to clean and replace the collection bottle 15 regularly. Based on this, as Figure 3 shown, a switch door 101 is also provided near the bottom of the side wall of the box body 1, so that users can take and place the collection bottle 15 through the switch door 101. The dried gas after being dried by the storage container 3 first discharges from the ventilation port 13 of the partition plate 11, enters the collection bottle 15, and flows out from the interval between the partition pieces 1501 on the side wall of the collection bottle 15. In this way, the flow direction and speed of the gas can be controlled, the turbulence and noise during gas flow can be reduced, and the design of the partition pieces 1501 can also help to evenly distribute the gas; secondly, a small amount of water can also be collected at the bottom of the collection bottle 15.

[0072] Based on the above embodiments, the embodiments of the present application further include a microwave humidity detector, which is used to detect the water content of the wet object to be dried. The microwave humidity detector uses microwave technology to detect the water content of the wet object to be dried. The working principle of the microwave detector mainly includes steps such as emitting microwave signals, the interaction between microwave signals and target objects, receiving reflected or scattered microwave signals, signal processing and analysis, and data parsing and recognition. During the propagation of microwave signals, they will interact with target objects through reflection, refraction, scattering, absorption, etc. By analyzing these changes, the humidity information of the object can be obtained. By detecting the water content of the wet object to be dried with a microwave humidity detector, the dry weight of the wet object to be dried can be calculated, that is, the weight of the wet object to be dried after drying.

[0073] Furthermore, it can also include a human-computer interaction module and a rechargeable battery. The human-computer interaction module is connected to the controller, and the human-computer interaction module is used for users to input data or instructions, etc. The rechargeable battery can supply power to the intelligent drying system.

[0074] In summary, the intelligent drying system of the present application actively adjusts the air humidity through desiccants, forms a humidity gradient, accelerates the drying process of wet objects, and does not need to use high-energy air heating methods such as electric heating and heat pumps, realizing the green energy saving and low carbon of wet object drying. This working principle abandons traditional drying and heating methods such as using electric heating and heat pumps, reduces heat exchange as much as possible, reduces the humidity in the closed system through the drying system, increases the humidity difference between the wet clothes and the air, artificially creates a large humidity gradient difference, and ensures that the air is always in a flowing state, promoting the directional gradient transfer of moisture, and finally achieving the rapid evaporation of moisture, realizing the low carbon, energy saving and high efficiency of wet object drying, and providing a double improvement of economic benefits and environmental benefits for the society.

[0075] Figure 8 is a flowchart of a control method for an intelligent drying system provided by an embodiment of the present application, asFigure 8 As shown, the control method of the intelligent drying system includes:

[0076] S10: Obtain the initial weight of the wet object to be dried, and obtain the weight of the wet object to be dried and the environmental humidity in the closed chamber in real time.

[0077] S11: Determine the evaporation rate of the wet object to be dried according to the weight of the wet object and the initial weight, and regulate the rotation speed of the fan according to the change of the evaporation rate and the environmental humidity.

[0078] S12: Determine the environmental humidity change rate according to the environmental humidity, and regulate the opening angle of the electric louver and the opening and closing ratio of the ventilation holes of the storage container according to the environmental humidity change rate.

[0079] In step S10, at the beginning of drying, the initial weight can be obtained by the weight sensor; during the drying process, the weight sensor monitors the weight of the wet object to be dried in real time; the temperature and humidity sensor monitors the environmental humidity and environmental temperature in the closed chamber in real time.

[0080] In step S11, determining the evaporation rate of the wet object to be dried according to the weight of the wet object and the initial weight includes: calculating the evaporation rate according to the first preset formula; the first preset formula is: ; where is the weight of the wet object (kg); is the initial weight (kg); is the evaporation rate (kg / s); is the integral of the evaporation rate of the wet object to be dried over time.

[0081] Regulating the rotation speed of the fan according to the change of the evaporation rate and the environmental humidity includes: if the current evaporation rate is greater than the evaporation rate at the previous moment, regulate the rotation speed of the fan to the maximum rotation speed; if the current evaporation rate is less than or equal to the evaporation rate at the previous moment, determine whether the difference between the current environmental humidity and the preset environmental humidity is greater than the preset value; if the difference is greater than the preset value, regulate the rotation speed of the fan to the maximum rotation speed; if the difference is less than or equal to the preset value, calculate the current rotation speed according to the current evaporation rate, and regulate the rotation speed of the fan to the current rotation speed.

[0082] Since the evaporation rate of the wet object to be dried first increases and then decreases, and the moisture content of the dried wet object decreases, the evaporation rate will gradually slow down. If the current evaporation rate is greater than the evaporation rate at the previous moment, it means that the drying speed of the wet object to be dried is accelerating. In this case, the rotation speed of the fan is adjusted to the maximum rotation speed to provide the maximum air flow to help further accelerate the drying process. If the current evaporation rate is less than or equal to the evaporation rate at the previous moment, the influence of the ambient humidity needs to be further considered; if the difference between the current ambient humidity and the preset ambient humidity is greater than the preset value, it indicates that the ambient humidity is too high, which is not conducive to the further drying of the wet object. In this case, the rotation speed of the fan is also adjusted to the maximum rotation speed to try to reduce the ambient humidity by increasing the air flow, thereby improving the drying conditions; if the difference between the current ambient humidity and the preset ambient humidity is less than or equal to the preset value, it means that the ambient humidity has approached or reached the ideal drying humidity. At this time, a suitable fan rotation speed (current rotation speed) is calculated according to the current evaporation rate, and the rotation speed of the fan is adjusted to this calculated value. Such an adjustment aims to maintain an effective drying speed while avoiding unnecessary energy consumption. Of course, calculating the current rotation speed according to the current evaporation rate and adjusting the rotation speed of the fan to the current rotation speed includes: if the current rotation speed is less than or equal to the minimum rotation speed of the fan, taking the minimum rotation speed as the current rotation speed and adjusting the rotation speed of the fan to the current rotation speed; if the current rotation speed is greater than the minimum rotation speed, adjusting the rotation speed of the fan to the current rotation speed. Among them, the minimum and maximum rotation speeds of the fan are determined by the physical properties of the fan and the requirements of the system design.

[0083] When the ambient humidity is less than 10%, the evaporation drying efficiency is significant; through experimental verification, the most ideal state of the intelligent drying system is to adjust the ambient humidity in the closed room to 10%. Therefore, the preset ambient humidity in the embodiments of the present application is 10%.

[0084] Further, calculating the current rotation speed according to the current evaporation rate includes: calculating the current rotation speed according to the second preset formula; the second preset formula is: ; where is the current evaporation rate (kg / s), indicating the mass of moisture evaporated from the surface of the wet object to be dried into the air per unit time; is the evaporation coefficient, which is determined through a large number of experiments and is related to factors such as the material of the wet object to be dried and the properties of the air. Under different materials and environmental conditions, the difficulty of moisture evaporation is different, and the evaporation coefficient k can comprehensively reflect the influence of these factors on the evaporation rate; is the current ambient saturation humidity (g / m³); is the current ambient humidity (g / m³), which is measured in real time by a temperature and humidity sensor and reflects the actual humidity situation of the current environment; is the current rotational speed (m / s), which affects the rate of moisture evaporation. A higher rotational speed generates a higher air flow rate, which can carry away the moisture evaporated from the surface of the wet material to be dried more quickly, promoting continuous moisture evaporation; is the weight correction function of the wet material to be dried. ; e is the natural exponential = 2.71828, is the initial weight (kg); is the current weight (kg). The weight correction function of the wet material to be dried takes into account the influence of the weight of the wet material to be dried on the evaporation rate. As the weight of the wet material to be dried increases, the difficulty of moisture evaporation also increases accordingly. The evaporation rate is corrected through this function to make the second preset formula more accurate. Among them, the current environmental saturation humidity is determined according to the current environmental temperature. The environmental temperature determines the maximum amount of water vapor that the air can hold. Call the temperature-humidity saturation curve table containing the corresponding relationship between the environmental saturation humidity and the environmental temperature, and look up the current environmental saturation humidity corresponding to the current environmental temperature.

[0085] In step S12, determining the environmental humidity change rate according to the environmental humidity includes: environmental humidity change rate = (environmental humidity at the previous moment - current environmental humidity) / time interval (Δt); Δt is the time interval between the current environmental humidity and the environmental humidity at the previous moment.

[0086] Regulating the opening angle of the electric louver and the opening and closing ratio of the ventilation holes of the storage container according to the environmental humidity change rate includes: Step A: When the difference between the current environmental humidity and the preset environmental humidity is greater than the preset value, control the electric louver to change the opening angle within the preset angle range at the preset angle gradient; Step B: Determine the environmental humidity change rate corresponding to each opening angle, and take the opening angle corresponding to the maximum environmental humidity change rate in the environmental humidity change rate as the target opening angle, and regulate the opening angle of the electric louver to the target opening angle and maintain it for the set time; Step C: Calculate the target ventilation hole opening and closing ratio according to the maximum environmental humidity change rate, and regulate the opening and closing ratio of the ventilation holes of the storage container to the target ventilation hole opening and closing ratio; Step D: After the set time, if the difference between the current environmental humidity and the preset environmental humidity is greater than the preset value, enter the step of controlling the electric louver to change the opening angle within the preset angle range at the preset angle gradient until the difference between the current environmental humidity and the preset environmental humidity is less than or equal to the preset value, and keep the current opening angle of the electric louver and the current opening and closing ratio of the ventilation holes of the storage container unchanged.

[0087] When the difference between the current environmental humidity and the preset environmental humidity is greater than the preset value, it indicates that the current environmental humidity is too high, and the opening angle of the electric louver needs to be adjusted. Control the electric louver to change the opening angle within the preset angle range at a preset angle gradient to find a better target opening angle. For example, the preset angle range is from 0° to 90°, and the preset angle gradient is 1°. If it is found that the environmental humidity change rate corresponding to 45° is the largest, it means that when the opening angle of the electric louver is adjusted from the previous moment to 45°, the environmental humidity drops the most during this period. Adjust the opening angle of the electric louver to 45° and maintain it for the set time; at the same time, calculate the target ventilation hole opening and closing ratio according to the maximum environmental humidity change rate, and adjust the ventilation hole opening and closing ratio of the storage container to the target ventilation hole opening and closing ratio.

[0088] Calculating the target ventilation hole opening and closing ratio according to the maximum environmental humidity change rate includes: calculating the target ventilation hole opening and closing ratio according to the third preset formula; the third preset formula is: ; where is the maximum environmental humidity change rate; is the correction coefficient (experimentally calibrated); is the target ventilation hole opening and closing ratio (%); is the desiccant efficiency (g / (kg·s)), which represents the mass of water absorbed by the desiccant per unit mass per unit time. Different types of desiccants have different moisture absorption efficiencies. This parameter is used to describe the effect of the desiccant in the dehumidification process; is the desiccant dosage (kg). The more desiccant participates in the mass, the greater the environmental humidity change rate; is the volume of the closed chamber; the size of the closed chamber volume determines the ability of the air to hold moisture. When calculating the humidity change, it is necessary to consider the volume of the closed chamber where the wet object to be dried is located to accurately reflect the distribution and change of moisture in the closed chamber. The larger the closed chamber volume, the smaller the relative environmental humidity change rate, and the smaller the closed chamber volume, the larger the relative environmental humidity change rate.

[0089] After the set time, if the difference between the current environmental humidity and the preset environmental humidity is still greater than the preset value, enter step A to control the electric louver to change the opening angle within the preset angle range at a preset angle gradient; sequentially execute step B and step C until the difference between the current environmental humidity and the preset environmental humidity is less than or equal to the preset value, and keep the current opening angle of the electric louver and the current ventilation hole opening and closing ratio of the storage container unchanged.

[0090] After step S12, determine the weight of the wet object to be dried after drying; when the difference between the weight of the wet object and the weight after drying is less than the set value, turn off the fan and the electric louver, and adjust the opening ratio of the ventilation hole to zero. Among them, determining the weight of the wet object to be dried after drying can be obtaining the value input by the user through the human-machine interaction module; it can also be: obtaining the initial water content of the wet object to be dried monitored by the microwave humidity detector; determining the weight after drying according to the initial weight and the initial water content. When the difference between the weight of the wet object and the weight after drying is less than the set value, it means that the wet object to be dried is almost dry, turn off the fan and the electric louver in time to reduce energy consumption; adjusting the opening ratio of the ventilation hole to zero is also to prevent the desiccant from continuing to dry.

[0091] A control method for an intelligent drying system provided by an embodiment of the present application is applied to the intelligent drying system, and includes: obtaining the initial weight of the wet object to be dried, and obtaining the weight of the wet object to be dried and the environmental humidity of the closed chamber in real time; determining the evaporation rate of the wet object to be dried according to the weight of the wet object and the initial weight, and regulating the rotation speed of the fan according to the change of the evaporation rate and the environmental humidity; determining the environmental humidity change rate according to the environmental humidity, and regulating the opening angle of the electric louver and the opening ratio of the ventilation hole of the storage container according to the environmental humidity change rate. The fan introduces the environmental air in the closed chamber into the box body, and after being dried by the desiccant in the storage container, it is discharged through the electric louver to form an air circulation; the dried air enters the closed chamber and forms a large humidity difference with the wet object to be dried, promoting the evaporation of the moisture in the wet object and realizing drying. The drying of the wet object to be dried is carried out in the closed chamber, reducing the influence of the drying effect by region and climate; drying is carried out by means of air circulation and desiccant adsorption, without using high-energy heating devices such as electric heating or heat pumps, realizing low energy consumption for drying the wet object to be dried, and reducing the risk of damage to the wet object to be dried by high temperature. Secondly, the controller is respectively connected to the fan, the ventilation regulating device, the electric louver, the weight sensor and the temperature and humidity sensor, and can realize intelligent control. By monitoring the weight of the wet object to be dried and the environmental humidity in real time, the evaporation rate and the environmental humidity change rate of the wet object to be dried can be determined, so as to dynamically adjust the rotation speed of the fan and the opening angle of the electric louver to maximize the drying efficiency; the intelligent control system can adjust the rotation speed of the fan and the opening ratio of the ventilation hole according to actual needs, avoid unnecessary energy consumption, and realize energy saving.
