Description

Technical Field

[0001] This invention relates to the field of drying technology, specifically to a drying rack. Background Technology

[0002] Sun-drying is an ancient and ingenious method of food preservation and flavor enhancement. Through the action of sunlight, wind, or the natural environment, it reduces the moisture content of ingredients, extending their shelf life while imparting a unique flavor.

[0003] In Guangdong and other regions, people are accustomed to drying food on their balconies. However, the drying process is often time-consuming, especially for foods with high water content such as fish. Currently, people simply lay the items on the ground to dry in the sun, but this method is not efficient and can easily lead to spoilage and unpleasant odors. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the prior art and provide a drying rack.

[0005] One embodiment of the present invention provides a drying rack, comprising: Main support; A shelf, which is rotatably mounted on the main support; A temperature and humidity detection component is installed on the main support or the shelf to detect the real-time temperature and humidity at the shelf. A light-tracking component includes several light detectors mounted on the shelf and a rotation drive module mounted on the main support. The light detectors are signal-connected to the rotation drive module and are used to detect real-time light intensity. The rotation drive module is drive-connected to the shelf and is used to drive the shelf to rotate to adjust the angle of the drying items relative to the direct sunlight direction. A heating component, which is mounted on the main support frame, is used to heat the items being dried. A weight detection component is mounted on the main support and connected to the shelf. The weight detection component determines the real-time weight of the items being dried by detecting the overall weight of the shelf. A blower assembly, which is mounted on the shelf, is used to blow airflow toward the items being dried; The weight detection component determines the real-time moisture content of the dried item based on its real-time weight. When the real-time moisture content is within a first preset range, the rotation drive module adjusts the angle of the shelf based on the real-time light intensity so that the items drying on the shelf face the sun, the heating component is activated to bring the real-time temperature to the highest safe temperature, and the blower component is activated. When the real-time moisture content is within a second preset range, the rotation drive module adjusts the angle of the shelf based on the real-time temperature and the real-time light intensity, and the heating component operates based on the real-time temperature to keep the real-time temperature within a first preset temperature range, and the blower component operates based on the real-time humidity to keep the real-time humidity within a first preset humidity range; When the real-time moisture content is within a third preset range, the rotation drive module adjusts the angle of the shelf based on the real-time temperature and the real-time light intensity, and the heating component operates based on the real-time temperature to keep the real-time temperature within a second preset temperature range. The blower component operates based on the real-time humidity to keep the real-time humidity within a second preset humidity range. Wherein, the first preset range > the second preset range > the third preset range, the maximum safe temperature ≥ the second preset temperature range > the first preset temperature range, and the first preset humidity range is greater than the second preset humidity range.

[0006] In some alternative implementations, the light-tracking component includes a plurality of light detectors, with the top and bottom of the shelf each having a plurality of light detectors.

[0007] In some alternative embodiments, the main support is provided with a mounting bracket located below the shelf, and the heating assembly includes multiple heating lamp modules arranged on the mounting bracket.

[0008] In some alternative embodiments, the blower assembly includes a fan and an air supply duct frame, the fan being disposed on one side of the shelf, the air supply duct frame being arranged on the shelf, the air supply duct frame being provided with a plurality of air supply holes, and the fan being connected to the air supply duct frame.

[0009] In some alternative implementations, a rainwater detection component is provided on the main support, and the rainwater detection component is signal-connected to the heating component and the blowing component respectively.

[0010] In some optional implementations, the maximum safe temperature is 60°C, the first preset temperature range is 45°C-55°C, and the second preset temperature range is 55°C-60°C.

[0011] In some optional implementations, the first preset humidity range is 65%-75%, and the second preset humidity range is 50%-60%.

[0012] In some optional embodiments, the drying rack also includes a main control module, which is mounted on the main support and has a wireless communication module. The main control module is connected to the temperature and humidity detection component, the light detector, the rotation drive module, the heating component, the weight detection component, and the air blowing component.

[0013] In some alternative implementations, the rotation drive assembly drives the shelf to rotate 180° every preset time.

[0014] In some optional embodiments, the main support is provided with a plurality of rain shelters and a plurality of power components, the power components being driven to the rain shelters, the rain shelters being moved under the drive of the power components to a shielding position directly above the shelf and to an avoidance position; The top of the rain shelter is equipped with a solar cell module, which is electrically connected to the heating module, the air blowing module and the rotary drive module.

[0015] Compared to existing technologies, the drying rack of this invention can determine the moisture content of the dried items using a weight detection component. It divides the drying process into three stages: "rapid drying," "slow drying," and "complete drying." Based on the moisture content of the items, it dynamically adjusts the rack angle, wind speed, and heating temperature to precisely delay the formation of the surface cuticle layer, ensuring unobstructed internal moisture migration channels, thereby improving drying efficiency and achieving thorough drying. It automatically tracks the direction of direct sunlight and performs timed turning, resulting in more even heating and improved drying effects. The blowing component effectively accelerates the replacement of humid air on the surface of the items. The design of the light-tracking component, heating component, and rain detection enables all-weather sunlight-tracking drying.

[0023] From a drying principle perspective, food follows a specific drying curve during the sun-drying process. During the constant-rate drying stage, the rate of moisture transport within the food is roughly equal to the rate of surface moisture evaporation. However, for some foods—such as meat and fish—when moisture evaporates to a certain extent, i.e., when the moisture content of the dried food decreases to a certain value, a dense cuticle layer begins to form on the surface. This layer hinders the migration of internal moisture to the surface, making it difficult to dry completely. In this case, even if the surface is dry, moisture may still remain inside, making it prone to dampness and mold growth after a period of storage.

[0024] This invention is specifically designed for the drying process of meat, fish and other dried items. By dynamically adjusting the temperature and humidity around the dried items during the drying process, it effectively slows down the formation of the cuticle layer, improves the drying effect, and effectively solves the problems of low efficiency and easy mold growth in humid climates caused by traditional drying methods.

[0025] Please see Figures 1 to 3 This invention provides a drying rack in one embodiment, comprising: Main support 10, shelf 20, temperature and humidity detection component 30, follow light component 40, heating component 50, weight detection component 60 and blower component 70; The shelf 20 is rotatably mounted on the main support 10.

[0026] The temperature and humidity detection component 30 is installed on the main support 10 or the shelf 20 to detect the real-time temperature and humidity at the shelf 20.

[0027] The light-tracking component 40 includes several photodetectors 41 mounted on the shelf 20 and a rotation drive module 42 mounted on the main support 10. The photodetectors 41 are signal-connected to the rotation drive module 42, and are used to detect real-time light intensity. The rotation drive module 42 is drive-connected to the shelf 20, and is used to drive the shelf 20 to rotate to adjust the angle of the clothes being dried relative to the direct sunlight. The photodetectors 41 can be photosensitive sensor arrays, etc. The real-time light intensity detected by the photodetectors 41 can determine the angle of the shelf 20 relative to the direct sunlight. The specific detection principle is well known to those skilled in the art and will not be described in detail here.

[0028] The heating element 50 is mounted on the main support 10 and is used to heat the clothes being dried. In rainy weather, the heating element 50 provides the main heat source to keep the clothes at a suitable drying temperature. On sunny days, the heating element 50 acts as an auxiliary heat source to keep the clothes at a suitable drying temperature. The specific heating efficiency of the heating element 50 needs to be adjusted according to the intensity of the sunlight. When the sunlight is strong, the clothes are dried at a higher temperature, and the heating element 50 can reduce its efficiency or be turned off. When the sunlight is weak, the heating element 50 can appropriately increase its heating efficiency.

[0029] The weight detection component 60 is mounted on the main support 10 and connected to the shelf 20. The weight detection component 60 determines the real-time weight of the drying items by detecting the overall weight of the shelf 20. The overall weight of the shelf 20 is equal to the shelf 20 plus the weight of the drying items placed on the shelf 20.

[0030] The blower assembly 70 is mounted on the shelf 20 and is used to blow airflow toward the items being dried.

[0031] The weight detection component 60 determines the real-time moisture content of the dried item based on its real-time weight. As the item dries, it gradually loses moisture, thus reducing its weight. Therefore, the real-time moisture content can be determined by its weight. The formula for calculating moisture content is: Moisture Content = (Wet Weight - Dry Weight) / Wet Weight. Wet weight is the weight before drying, and dry weight is the weight after complete drying. Therefore, the real-time moisture content can be determined by the item's weight during the drying process and its dry weight after drying. Of course, the method for calculating real-time moisture content is common knowledge, and the dry weight of some items can be determined through experience and known data; it is not necessary to dry every item once to obtain the corresponding dry weight.

[0032] The following describes the phased dynamic drying process of a drying rack according to an embodiment of the present invention: The real-time moisture content is divided into three ranges: a first preset range, a second preset range, and a third preset range, with the first preset range > the second preset range > the third preset range. Based on the real-time moisture content of the dried item falling within these three preset ranges, three drying strategies are adopted: a rapid drying strategy, a slow drying strategy, and an accelerated drying strategy.

[0033] It should be noted that the moisture content at which the stratum corneum begins to form on the dried item is the turning point between the first and second preset ranges. For example, the critical moisture content for the formation of the stratum corneum is 60%, which is the turning point between the first and second preset ranges. Since the real-time moisture content of the dried item gradually decreases during the drying process, when the real-time moisture content drops to the level at which the stratum corneum begins to form, it is necessary to switch from a rapid drying strategy to a slow drying strategy. Based on drying experience with different dried items, when the drying rate decreases significantly, the corresponding real-time moisture content is the turning point between the second and third preset ranges. Therefore, at this point, it is necessary to switch from a slow drying strategy to an accelerated drying strategy. The moisture content at which the drying rate decreases significantly varies for each type of dried item, generally around the point when the stratum corneum is fully formed. However, since it is difficult to determine whether the stratum corneum has fully formed, the approximate moisture content is usually determined based on drying experience to correspond to the moisture content at which the drying rate decreases significantly.

[0034] In the rapid drying strategy, when the real-time moisture content is within a first preset range, the rotary drive module 42 adjusts the angle of the rack 20 based on the real-time light intensity to ensure the items on the rack 20 face the sun, making the surface of the items as perpendicular as possible to the direct angle of the sun. This ensures the items are facing the sun, achieving a light-tracking function, which promotes more even and comprehensive heating. The heating component 50 is activated to maintain the real-time temperature at the highest safe temperature, thus ensuring drying efficiency. Of course, if the temperature of the items can still roughly reach the highest safe temperature without the heating component 50 being activated, then the heating component 50 does not need to be activated. The blower component 70 is activated and operates at its maximum power within a suitable range. At this initial stage of drying, the items release a lot of moisture, so the blower component 70 is activated to quickly remove the moisture around the items, which helps to improve the drying rate.

[0035] The slow drying strategy involves adjusting the angle of the rack 20 based on real-time temperature and light intensity when the real-time moisture content is within a second preset range. This prevents the rack from forming a cuticle layer too quickly, hindering moisture loss. The rotation drive module 42 adjusts the angle of the rack 20 based on real-time temperature and light intensity, while the heating component 50 operates based on real-time temperature to maintain the real-time temperature within a first preset temperature range. If the sunlight is too strong, causing the real-time temperature to be too high, the rack 20 adjusts its angle to prevent the temperature from exceeding the first preset temperature range. In this case, the heating component 50 does not activate. Conversely, if the real-time temperature is insufficient, the rotation drive module 42 drives the rack 20 to actively follow the sunlight, fully utilizing solar energy and reducing energy consumption. The heating component 50 also activates to assist heating, ensuring the real-time temperature reaches the first preset temperature range, which is the lowest temperature range during the entire drying process, thus reducing the rate of moisture loss. The blower component 70 operates based on real-time humidity to maintain the real-time humidity within a first preset humidity range, ensuring a higher humidity level and increasing the humidity of the surrounding environment, thus slowing down surface evaporation. By lowering the temperature and increasing the humidity, the surface is kept at a certain level of moisture, thereby delaying the formation of the cuticle layer on the dried item and ensuring that the internal moisture migration channels are unobstructed.

[0036] The accelerated drying strategy involves adjusting the angle of the rack 20 and the heating component 50 based on real-time temperature and light intensity to maintain the real-time temperature within a second preset temperature range. If the sunlight is too strong, causing the real-time temperature to exceed the second preset range, the rack 20 is adjusted to prevent it from exceeding this range, and the heating component 50 remains inactive. Conversely, if the real-time temperature is insufficient, the rotation drive module 42 drives the rack 20 to actively follow the sunlight, maximizing solar energy utilization and reducing energy consumption. The heating component 50 also activates to assist heating, ensuring the real-time temperature reaches the second preset range, which is higher than the first preset range. This increased temperature drives internal moisture diffusion, improving drying efficiency. The air blowing component 70 operates based on real-time humidity to maintain the humidity within a second preset range, which is lower than the first preset range. This reduced humidity maintains adequate evaporation, further enhancing drying efficiency.

[0037] It should be noted that the first, second, and third preset ranges need to be determined based on the actual dried material. Different dried materials have different water contents when they begin to form a cuticle and when they are fully formed. Taking fish as an example, according to experimental results, the critical water content for the formation of the cuticle in fish is about 58% to 68%, and the critical water content for the formation of the cuticle in beef is about 60% ± 2%.

[0038] Of course, the drying rack of the present invention is not limited to drying fish and meat, but can also be used for other suitable items, such as dried tangerine peel. For items that do not form a cuticle layer, but where there is a turning point in the drying process where the rate of moisture migration is less than the rate of external moisture evaporation, and the moisture content of the item decreases to the level corresponding to that turning point, the fast drying strategy is switched to a slow drying strategy. Of course, the drying rack of the present invention can also employ other suitable drying strategies depending on the specific item being dried, and is not limited to the drying strategies described above.

[0039] The time interval for the rotation drive assembly to adjust the angle of the shelf 20 can be designed as needed. For example, the intensity of sunlight is detected by the light detector 41 every ten seconds, and then the rotation drive assembly adjusts the shelf 20.

[0040] It should be noted that the maximum safe temperature ≥ the second preset temperature range > the first preset temperature range. Proteins are prone to denaturation at 60℃-65℃, causing the surface of the dried item to harden and form a crust rapidly. Therefore, the maximum safe temperature should not exceed the temperature at which proteins are easily denatured. In some optional embodiments, the maximum safe temperature is 60℃, the first preset temperature range is 45℃-55℃, and the second preset temperature range is 55℃-60℃. In this embodiment, the real-time temperature is maintained at approximately 50℃ in the slow drying strategy, while in the accelerated drying strategy, the real-time temperature is maintained at approximately 60℃.

[0041] It should be noted that the first preset humidity range is 65%-75%, and the second preset humidity range is 50%-60%. The specific first and second preset humidity ranges are determined according to the type of items being dried.

[0042] In some optional embodiments, the light-tracking component 40 includes multiple light detectors 41, with multiple light detectors 41 provided at both the top and bottom of the shelf 20. By providing light detectors 41 at both the top and bottom of the shelf 20, the direction of direct sunlight can be detected regardless of whether the top or bottom surface of the shelf 20 is facing upwards, and the light detectors 41 are switched accordingly based on whether the top or bottom surface of the shelf 20 is facing upwards.

[0043] The specific structure of the heating component 50 can be designed according to actual needs. For example, in some optional embodiments, the main support 10 is provided with a mounting frame 11 located below the shelf 20. The heating component 50 includes multiple heating lamp modules 51, which are arranged on the mounting frame 11. The heating lamp modules 51 generate heat, thereby heating the clothes drying on the shelf 20 above. In the presence of sunlight, the top of the clothes is heated by sunlight, and the bottom of the clothes is heated by the heating lamp modules 51, thereby effectively improving the uniformity of heating.

[0044] Please see Figure 4 The specific structure of the blower assembly 70 can be designed according to actual needs. For example, in some optional embodiments, the blower assembly 70 includes a fan 71 and an air supply duct frame 72. The fan 71 is located on one side of the shelf 20, and the air supply duct frame 72 is arranged on the shelf 20. The air supply duct frame 72 is provided with multiple air supply holes 721. The fan 71 is connected to the air supply duct frame 72, and the air supply duct frame 72 can extend to different positions of the shelf 20, so that the airflow blown by the fan 71 can be delivered to different positions of the shelf 20 through each air supply hole 721. This allows the airflow to more comprehensively cover the surface of the drying items, greatly enhances the surface airflow of the drying items, effectively breaks the saturated humid air layer stagnating on the surface of the drying items, continuously maintains high evaporation driving force, and ensures no ventilation dead corners.

[0045] The specific structure of the air supply duct frame 72 can be designed according to actual needs. For example, the air supply duct frame 72 can consist of multiple longitudinal air ducts arranged side by side and multiple transverse air ducts arranged side by side. The longitudinal air ducts and transverse air ducts are arranged to cross each other and are interconnected. Multiple air supply holes 721 are arranged on both the longitudinal air ducts and the transverse air ducts.

[0046] In some alternative implementations, the blower assembly 70 operates based on real-time humidity by adjusting the operating power of the blower assembly 70, thereby adjusting the airflow velocity of the air blower assembly 70. By adjusting the airflow velocity, the real-time humidity at the shelf 20 can be adjusted. When the airflow velocity decreases, the rate at which the airflow carries away moisture is slower, while the clothes being dried will continuously evaporate moisture. The rate of moisture evaporation is faster than the rate at which the airflow carries away moisture, thus increasing the real-time humidity.

[0047] In some alternative implementations, the rotary drive assembly drives the rack 20 to rotate 180° every preset time, thereby ensuring that each side of the item being dried is periodically exposed to optimal light and airflow, fundamentally solving the problems of localized shading and uneven drying rates on both sides caused by static drying. Furthermore, since sunlight shines from above the item, while the heating assembly 50 heats it from below, the periodic rotation helps improve the uniformity of heating. The preset time can be five seconds, ten seconds, etc.

[0048] In addition, in this embodiment, the shelf 20 is provided with a storage slot and a cover 21. The storage slot can be used to store clothes for drying, and the air supply duct bracket 72 is installed inside the storage slot. The cover 21 is used to close the storage slot and prevent the clothes stored in the storage slot from falling out due to the rotation of the shelf 20. Of course, depending on the type of clothes being dried, other suitable methods can also be used to fix the clothes to the shelf 20, such as using clips or ropes.

[0049] In some optional embodiments, a rain detection component is provided on the main support 10. This component is signal-connected to both the heating component 50 and the air blowing component 70. The rain detection component can detect the current environmental conditions. In rainy weather, due to the lack of sunlight, only the heating component 50 can provide heat, requiring it to operate at higher power. Furthermore, the rotation drive component can drive the rack 20 to rotate in a shorter time than the preset time, thus preventing uneven heating of the clothes due to only one side being heated.

[0050] In some optional embodiments, the drying rack also includes a main control module 80, which is mounted on the main support 10. The main control module 80 is equipped with a wireless communication module 81 and is connected to the temperature and humidity detection component 30, the light detector 41, the rotation drive module 42, the heating component 50, the weight detection component 60, and the air blowing component 70. The main control module 80 can be a main control board with a processor, a micro calculator, etc. The main control module 80 can send detection and operation information from the temperature and humidity detection component 30, the light detector 41, the rotation drive module 42, the heating component 50, the weight detection component 60, and the air blowing component 70 to the wireless communication module 81. The wireless communication module 81 can establish wireless communication with the user's terminal device, sending the detection and operation information to the user's terminal device so that the user can check the drying status. The user can also send control signals to the wireless communication module 81 through the terminal device, and the wireless communication module 81 will send the control signals to the main control module 80. The main control module 80 controls the rotation drive module 42, the heating component 50, and the air blowing component 70 based on the control signals. The terminal device can be a mobile phone, tablet, computer, etc. Taking a mobile phone as an example, a corresponding control APP can be installed on the mobile phone for user operation.

[0051] The specific structure of the rotary drive module 42 can be designed according to actual needs. For example, the rotary drive module 42 can adopt a stepper motor.

[0052] The specific structure of the weight detection component 60 can be designed according to actual needs. For example, the two sides of the shelf 20 are rotatably connected to the main support 10 via pivots, and the weight detection component 60 includes two pressure sensors corresponding to the pivots. Alternatively, in this embodiment, the weight detection component 60 includes multiple pressure sensors, which are located at the bottom of the main support 10. The real-time weight of the drying item is determined by detecting the total weight of the shelf 20, the main support 10, and the drying item.

[0053] Please see Figure 5 In some optional embodiments, the main support 10 is provided with a plurality of rain shelters 90 and a plurality of power components 91. The power components 91 are driven by the rain shelters 90. Under the drive of the power components 91, the rain shelters 90 move to a shielding position directly above the shelf 20 and to a clearance position. In rainy weather, the power components 91 drive the rain shelters 90 to move directly above the shelf 20, thereby shielding the shelf 20 from rain and preventing rainwater from falling on the clothes drying on the shelf 20. In sunny weather, the power components 91 drive the rain shelters 90 to a clearance position, thereby preventing the rain shelters 90 from blocking sunlight. The clearance position of the rain shelters 90 can be selected according to actual needs and the driving stroke of the power components 91.

[0054] In this embodiment, the rain shelter 90 is rotatably mounted on the main support 10, and the power component 91 is a drive motor, the output shaft of which is drivenly connected to the rain shelter 90.

[0055] Rain shelters 90 can be made of suitable materials such as acrylic sheets or metal sheets that can block rainwater.

[0056] The top of the rain shelter 90 is equipped with a solar cell module (not shown in the figure). The solar cell module is electrically connected to the main control board, thereby enabling the solar cell module to be electrically connected to components that require power supply, such as the heating component 50, the blowing component 70, the rotary drive module 42, and the power component 91.

[0057] Solar cell modules typically include solar panels and batteries. The solar panels can be mounted on top of the awning (90°), while the batteries can be located elsewhere. The batteries can be charged via the solar panels or an external power source, enabling them to power other electrical components. Drying racks can be placed in suitable locations as needed, without being restricted by the location of mains outlets.

[0058] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
