Description

Technical Field

[0001] This invention relates to the field of household appliance technology, and more specifically, to a drying device, method, apparatus, equipment, and medium. Background Technology

[0002] Currently, after completing the washing and rinsing stages, household dishwashers typically require drying of the dishes and the inner drum. Existing dishwasher drying technologies mainly include condensation drying, residual heat drying, and forced draft drying. Among these, forced draft drying technology has become the mainstream solution due to its high drying efficiency. This technology usually involves setting up an independent air duct outside the dishwasher's inner drum, within which a DC carbon brush fan (mechanical fan) and a heater are arranged sequentially. During operation, the control module activates the fan and heater. The fan's rotation generates negative pressure, drawing in cold outside air into the air duct. After being heated by the heater, the hot air is blown into the dishwasher's inner drum. The hot air circulates within the drum, carrying away moisture from the surface of the dishes, and finally, the moisture is expelled from the machine through the exhaust vent.

[0003] However, the aforementioned forced-draft drying technology has the following shortcomings in practical applications: First, it causes serious noise pollution. Because a small DC carbon brush fan is used as the air source, the operation of the motor and the cutting of air by the fan blades inevitably generate fluid noise and mechanical vibration. In a quiet home environment, the noise during the drying stage seriously affects the user experience. Second, it has a complex structure and is prone to failure. The mechanical fan contains multiple moving parts such as motors, bearings, and fan blades. In the high-temperature and high-humidity working environment of a dishwasher, the lubricating oil is prone to drying out and the bearings are prone to wear, resulting in a shortened lifespan and a higher failure rate. Third, it has relatively high energy consumption. The speed and air volume of the mechanical fan are difficult to adjust linearly over a wide range. In order to achieve sufficient drying effect, it often runs continuously at a fixed high level, causing unnecessary waste of electricity.

[0004] Therefore, how to completely eliminate the noise during the drying stage of a dishwasher, while improving the reliability of the drying system and reducing energy consumption, is a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, embodiments of the present invention provide a drying device, method, apparatus, equipment, and medium to solve the problems of high drying noise, easy failure of moving parts, high energy consumption, and poor user experience in the prior art.

[0006] One aspect of the present invention provides a drying device, the device including an air duct, an air inlet and an air outlet, the air inlet being in communication with the outside air, and the air outlet being in communication with the inner liner of the drying device; A discharge component is disposed in the air duct and is used to generate directional plasma wind through corona discharge, and drive outside air into the air duct through the directional plasma wind to form a drying airflow; A heating module is installed inside the air duct to heat the drying airflow to form hot drying air, and to send the hot drying air into the inner liner of the drying equipment. The control module is electrically connected to the discharge component and is used to control the start and stop of the discharge component and the intensity of the corona discharge.

[0007] The present invention also discloses a drying control method, the method being implemented based on the drying equipment described above, the method comprising: After the drying equipment completes the preset cleaning program, obtain the current humidity of the inner tank; When the current humidity of the inner chamber is lower than the preset humidity safety threshold, the discharge component and the heating module are activated; so that the discharge component generates directional plasma wind through corona discharge, drives the outside air to flow into the drying equipment through the air duct, and is heated by the heating module to form drying hot air which is sent into the inner chamber of the drying equipment. The drying process is carried out based on the drying hot air, and during the drying process, the current inner liner humidity is re-acquired as the real-time inner liner humidity. Based on the real-time humidity of the inner liner, the corona discharge intensity of the discharge component is adjusted to regulate the plasma airflow entering the drying equipment. If the real-time humidity of the inner liner is not greater than the preset drying completion threshold, the discharge component and the heating module are turned off to stop the drying process.

[0008] The present invention also discloses a drying control device, which is based on the drying equipment described above, and the device includes: The current humidity acquisition module is used to acquire the current humidity of the inner tank after the drying equipment has completed the preset cleaning program; The start-up module is used to control the start-up of the discharge component and the heating module when the current humidity of the inner chamber is lower than a preset humidity safety threshold; so that the discharge component generates directional plasma wind through corona discharge, drives the outside air to flow into the drying equipment through the air duct, and is heated by the heating module to form drying hot air which is sent into the inner chamber of the drying equipment. The real-time humidity acquisition module is used to perform the drying process based on the drying hot air, and to reacquire the current inner liner humidity as the real-time inner liner humidity during the drying process. An adjustment module is used to adjust the corona discharge intensity of the discharge component based on the real-time humidity of the inner tank, so as to adjust the plasma airflow entering the drying equipment. The stop module is used to control the shutdown of the discharge component and the heating module to stop the drying process when the real-time inner tank humidity is not greater than the preset drying completion threshold.

[0009] Another aspect of the present invention provides an electronic device, comprising: processor; Memory used to store the processor's executable instructions; The processor is configured to execute the instructions to implement the drying control method described above.

[0010] Another aspect of the present invention provides a computer-readable storage medium that, when instructions in the storage medium are executed by a processor of an electronic device, enables the electronic device to perform the drying control method described above.

[0011] This invention provides a drying device comprising an air duct, a discharge component, a heating module, and a control module. The discharge component and the heating module are respectively disposed within the air duct, and the control module is electrically connected to the discharge component. The air duct has an air inlet and an air outlet, the air inlet being connected to the outside air and the air outlet being connected to the inner chamber of the drying device. The discharge component generates directional plasma wind through corona discharge and drives outside air into the air duct to form a drying airflow. The heating module heats the drying airflow to form hot drying air and sends the hot drying air into the inner chamber of the drying device. The control module controls the start-up and shutdown of the discharge component and the intensity of the corona discharge. Through the technical solution of this application, plasma wind is used to completely replace the traditional mechanical fan as the airflow driving source, eliminating mechanical noise and wear of moving parts at the source, and significantly improving the user experience and system reliability while ensuring the drying effect.

Detailed Implementation

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

For example, multiple modules or components may be combined or integrated into another system, or some features may be ignored or not executed. Furthermore, the coupling or direct coupling or communication connection shown or discussed may be through some interfaces, indirect coupling or communication connection between modules or units, and may be electrical or other forms.

[0016] In one specific embodiment, the drying device in this application can be applied to a kitchen. Optionally, the drying device designed in this application can be a dishwasher or other equipment. Specifically, this application takes a dishwasher as an example to introduce the drying device of this application.

[0017] Figure 1 This is a schematic diagram of a drying device according to an exemplary embodiment. This specification provides method operation steps as shown in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operation steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many and does not represent the only execution order. In actual system or server products, the methods shown in the embodiments or drawings can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown... Figure 1 As shown, an embodiment of a drying device according to this application is introduced. The drying device may include an air duct, which is provided with an air inlet and an air outlet. The air inlet is connected to the outside air, and the air outlet is connected to the inner liner of the drying device. A discharge component is disposed in the air duct and is used to generate directional plasma wind through corona discharge, and drive outside air into the air duct through the directional plasma wind to form a drying airflow; A heating module is installed inside the air duct to heat the drying airflow to form hot drying air, and to send the hot drying air into the inner liner of the drying equipment. The control module is electrically connected to the discharge component and is used to control the start and stop of the discharge component and the intensity of the corona discharge.

[0018] In a specific embodiment, the drying equipment may include an air duct 11, a discharge component 22, a heating module 33, and a control module 44. The air duct 1 is provided with an air inlet 1-1 and an air outlet 1-2. The air inlet 1-1 is connected to the outside air, and the air outlet 1-2 is connected to the inner liner of the drying equipment, forming an airflow channel for outside air to enter the inner liner. The discharge component 2 is disposed within the air duct 1 and generates directional plasma wind through corona discharge effect. Specifically, the plasma wind can drive outside air to actively flow into the air duct 1 and form a drying airflow. Optionally, the plasma wind can be a directional airflow generated by corona discharge effect under high voltage. Optionally, the formation mechanism of the plasma wind is as follows: when a high voltage of several kilovolts is applied between the discharge electrode and the ground electrode 2-2, a strong electric field is formed around the electrode tip, causing gas molecules in the air (mainly nitrogen and oxygen) to ionize, generating a large number of positive and negative ions and free electrons, forming a plasma region. These charged particles then accelerate towards the electrode of opposite polarity under the action of the strong electric field. During the process, plasma wind frequently collides with a large number of neutral air molecules, transferring some of its kinetic energy to the neutral molecules through momentum exchange. This drives the neutral air molecules to move directionally along the electric field direction, forming a continuous and uniform airflow on a macroscopic scale. Optionally, unlike the airflow generated by traditional mechanical fans, plasma wind does not require any mechanical moving parts (such as motors, fan blades, etc.) and relies entirely on electric field force to drive airflow. It has the characteristics of being noiseless, having no mechanical wear, and having finely adjustable airflow. Therefore, in this invention, plasma wind serves as the driving source of the drying airflow, replacing the DC carbon brush fan in the traditional dishwasher drying system, fundamentally eliminating mechanical noise and vibration, while improving the system's reliability and service life. The heating module 3 is also located in the air duct 1 and is used to heat the drying airflow to form drying hot air, which is then sent into the inner liner of the drying equipment to dry the tableware and the surface of the inner liner. The control module 4 is electrically connected to the discharge component 2 and is used to control the start and stop of the discharge component 2 and the intensity of the corona discharge, thereby achieving precise management of the generation and regulation of plasma wind.

[0019] In an optional embodiment, the discharge assembly is a needle-plate electrode structure, including at least one positive high-voltage electrode and one ground electrode.

[0020] In a specific embodiment, such as Figure 2As shown, the needle-plate electrode structure refers to an electrode system consisting of at least one positive high-voltage electrode 2-1 (as a needle electrode) with a pointed tip or sharp edge and a plate-shaped or planar ground electrode 2-2 (as a plate electrode) arranged opposite to each other. The needle electrode, as a discharge electrode, can form a strong electric field concentration effect at a lower voltage, thereby significantly reducing the initiation voltage of corona discharge and improving discharge efficiency. The ground electrode 2-2 serves as a counter electrode, forming a potential difference with the needle electrode to provide a directional electric field for the accelerated movement of charged particles. Optionally, there can be one or more needle electrodes. When multiple needle electrodes are set, they can be arranged in an array to expand the plasma wind generation area and enhance the airflow driving force. During operation, the control module 4 applies a high-voltage DC current of several kilovolts between the needle electrode and the ground electrode 2-2. Corona discharge occurs at the tip of the needle electrode, ionizing the surrounding air to generate a large number of ions. Under the action of the electric field, the ions accelerate towards the ground electrode 2-2 and drive neutral air molecules to move directionally through collisions, thereby forming a continuous plasma wind.

[0021] In the above embodiments, the needle electrode tip forms a strong electric field concentration effect, which can significantly reduce the starting voltage of corona discharge and improve discharge efficiency. At the same time, the structure is simple and compact, easy to integrate in the limited space of the dishwasher, and the discharge is stable and reliable, which is conducive to the continuous and uniform generation of plasma wind.

[0022] In an optional embodiment, the positive high voltage electrode is made of a metallic material; the grounding electrode is a perforated metal barrel structure.

[0023] In one specific embodiment, the positive high-voltage electrode 2-1 is made of a metallic material, specifically stainless steel, tungsten, or copper. Optionally, the metallic material possesses good conductivity and mechanical strength, enabling it to withstand ion bombardment during long-term corona discharge without significant wear. Simultaneously, the metal tip is easily processed into a sharp shape, which facilitates the formation of a strong electric field concentration effect and reduces the discharge initiation voltage. The grounding electrode 2-2 adopts a perforated metal barrel structure, i.e., it is cylindrical or tubular in shape, with multiple through holes distributed on its surface. Optionally, the barrel structure encloses or partially encloses the positive high-voltage electrode 2-1, forming a three-dimensional electrode configuration. The grounding electrode 2-2 in this application is designed as a perforated metal barrel structure because: the barrel structure provides greater... The grounding surface area enhances the uniformity of the electric field distribution; the through holes allow the plasma wind to pass smoothly, reducing airflow resistance and ensuring the drying air volume; the barrel structure can effectively shield external electric field interference, making the discharge process more stable; the perforated metal barrel structure confines the corona discharge area inside the barrel, reducing the diffusion of ozone to the outside of the air duct 1; optionally, the positive high voltage electrode 2-1 and the perforated metal barrel grounding electrode 2-2 are set coaxially or eccentrically, maintaining a preset discharge gap between them. Thus, during operation, a high voltage is applied between the positive high voltage electrode 2-1 and the barrel grounding electrode 2-2, and corona discharge occurs at the tip of the needle electrode. The generated ions accelerate towards the inner wall of the barrel under the action of the radial electric field, while simultaneously driving air molecules to flow axially, forming a directional plasma wind.

[0024] In the above embodiments, the positive high-voltage electrode 2-1 is made of metal, possessing good conductivity and mechanical strength, and can withstand long-term corona discharge ion bombardment without easy wear. The grounding electrode 2-2 is a perforated metal barrel structure. Its barrel design enhances the uniformity of the electric field distribution and shields external interference. The through-hole structure allows the plasma wind to pass smoothly, reducing airflow resistance, while confining the discharge area within the barrel to reduce ozone diffusion. This structure provides stable discharge, high efficiency, and low airflow resistance, making it suitable for confined spaces such as dishwashers.

[0025] In an optional embodiment, at least one electrode surface in the discharge assembly is coated with a nano-coating.

[0026] In one specific embodiment, the nano-coating 2-3 can be a functional thin film coating with a thickness on the order of nanometers to micrometers. Optionally, the nano-coating 2-3 can impart specific physical or chemical properties to the electrode surface without significantly changing the original geometric dimensions of the electrode. Optionally, in order to solve the adverse effects of the high temperature and humidity environment inside the dishwasher on the plasma air generation effect, the present invention coats at least one electrode surface of the discharge component 2 with the nano-coating 2-3. Specifically, during the operation of the dishwasher, a large amount of water vapor will remain in the inner tub and air duct 1. If water droplets adhere to the surface of the high-voltage discharge electrode or the grounding electrode 2-2, the following negative effects will occur: First, water droplets, as a conductive medium, will cause distortion of the electric field distribution, weaken the electric field concentration effect at the electrode tip, thereby increasing the starting voltage of the corona discharge or even causing the discharge to fail; Second, water droplets may connect the gap between the positive high-voltage electrode 2-1 and the grounding electrode 2-2, causing local creepage or short circuit phenomena, damaging the high-voltage power supply; Third, long-term high humidity environment will accelerate the electrochemical corrosion of the electrode material and shorten the discharge time. The lifespan of component 2 can be extended by coating the electrode surface with a nano-coating 2-3, which effectively solves the above problems. Optionally, the nano-coating 2-3 of the present invention preferably uses a hydrophobic material, such as modified silica or fluorinated polymer. Specifically, the nano-coating 2-3 imparts superhydrophobic properties to the electrode surface, making water droplets spherical with a contact angle greater than 150° on the electrode surface, making them difficult to adhere stably. Even if water droplets form, they will quickly roll off due to gravity or airflow, thus keeping the electrode surface dry and clean. In addition, the nano-coating 2-3 has certain insulating properties, which can prevent the continuous formation of water film on the electrode surface and block the creepage path. Furthermore, the nano-coating 2-3 can isolate the electrode substrate from direct contact with humid air, playing a role in corrosion protection and extending the lifespan of the electrode. Optionally, in terms of the preparation process, the nano-coating 2-3 can be coated by sol-gel method or chemical vapor deposition method, and the coating thickness is controlled in the micrometer range, such as 1-10 micrometers, to ensure the uniformity and adhesion of the coating, while avoiding the effect of electric field concentration at the electrode tip due to excessive coating thickness.

[0027] In the above embodiments, the nano-coating imparts superhydrophobic properties to the electrode surface, making it difficult for water droplets to adhere or roll off quickly, thus preventing electric field distortion, discharge failure, or short circuit caused by water droplets. At the same time, the nano-coating can isolate the electrode substrate from direct contact with humid air, playing a role in corrosion protection and ensuring that the discharge component 2 can work stably for a long time in the high humidity environment of the dishwasher, thus ensuring the reliable generation of plasma wind.

[0028] In an optional embodiment, the drying device further includes at least one humidity sensor disposed in the inner liner of the drying device, and the signal output terminal of the humidity sensor is connected to the control module for real-time detection of the humidity of the inner liner.

[0029] In one specific embodiment, a humidity sensor is used to detect the air humidity in the inner liner in real time, thereby indirectly reflecting the dryness of the tableware and the surface of the inner liner. Optionally, the humidity sensor can be a capacitive humidity sensor, a resistive humidity sensor, or an integrated temperature and humidity sensor. Specifically, the humidity sensor can be set at the top, bottom, or side wall of the inner liner, or multiple humidity sensors can be set at multiple locations in the inner liner to improve the accuracy and uniformity of detection. Furthermore, the signal output terminal of the humidity sensor is connected to the control module 4 via a signal line or wirelessly, transmitting the detected inner liner humidity data to the control module 4 in real time. Then, the control module 4 determines the current drying progress and whether the drying operation needs to be started, maintained, adjusted, or stopped based on the received humidity data.

[0030] In the above embodiments, the humidity sensor can detect the humidity of the inner tank in real time, providing accurate feedback data to the control module 4. This allows the system to intelligently start and stop and adjust the air volume according to the actual degree of dryness, avoiding energy waste or incomplete drying caused by traditional timed drying methods. This achieves closed-loop control and on-demand operation of the drying process.

[0031] In an optional embodiment, the control module includes a main control board and a high-voltage drive power supply; the main control board is connected to the high-voltage drive power supply and controls the average voltage applied to the discharge component by outputting pulse width modulation signals with different duty cycles, so as to adjust the plasma airflow entering the drying equipment.

[0032] In one specific embodiment, the duty cycle can be the ratio of the high-level duration to the signal period; specifically, the main control board is the core control unit, which usually uses an MCU (microcontroller unit) as the control chip, and integrates a PWM (pulse width modulation) signal generation module; the high-voltage drive power supply is electrically connected to the main control board, receives the control signal output by the main control board, and generates the high-voltage power required to drive the discharge component 2 according to the signal; Specifically, Pulse Width Modulation (PWM) is a technique that controls analog circuits by adjusting the duty cycle of a digital signal. Specifically, the main control board outputs a PWM signal to the high-voltage drive power supply. Correspondingly, the duty cycle of the PWM signal determines the average voltage output by the high-voltage drive power supply. Specifically, when the duty cycle of the PWM signal is high, the average voltage output by the high-voltage drive power supply is higher, the voltage applied to the discharge component 2 increases accordingly, the corona discharge intensity is enhanced, and the generated plasma wind speed and volume increase. Conversely, when the duty cycle of the PWM signal is low, the average voltage decreases, and the plasma wind volume decreases. Optionally, since the generation of plasma wind relies on the electric field force to drive ions to accelerate and collide with neutral molecules, its wind speed is approximately proportional to the square of the applied voltage, and there is no inertial lag problem of mechanical fans. Therefore, the plasma air volume can be quickly, accurately, and steplessly adjusted by adjusting the voltage through the PWM signal. The main control board can dynamically adjust the duty cycle of the PWM signal according to the real-time humidity value fed back by the humidity sensor, thereby realizing the on-demand supply of plasma air volume entering the inner tank of the drying equipment.

[0033] In the above embodiments, the plasma air volume can be quickly, accurately, and steplessly adjusted using PWM signals, eliminating the inertial lag problem of traditional mechanical fans. This provides a hardware foundation for on-demand air supply based on humidity feedback, thereby improving energy efficiency and control accuracy.

[0034] In an optional embodiment, the control module is configured to activate the discharge component when the drying equipment completes a preset cleaning procedure and the current inner tank humidity detected by the humidity sensor is lower than a preset humidity safety threshold; and to dynamically adjust the duty cycle of the pulse width modulation signal according to the real-time inner tank humidity detected by the humidity sensor during the drying process, so as to adjust the plasma airflow entering the drying equipment.

[0035] In one specific embodiment, the preset cleaning program may include a washing stage program, a rinsing stage program, and a draining stage program; the current inner tank humidity may be the relative humidity value of the air inside the inner tank first detected by the humidity sensor after the drying equipment completes the preset cleaning program; optionally, the current inner tank humidity may reflect the residual moisture status inside the inner tank after draining; the preset humidity safety threshold may be the humidity critical value for whether the discharge component 2 is allowed to be started; the real-time inner tank humidity may be the relative humidity value of the air inside the inner tank continuously collected by the humidity sensor at a preset sampling frequency and transmitted in real time to the control module 4 during the drying process. Specifically, the control module 4 does not immediately start the discharge component 2 after the cleaning program ends. Instead, it starts only when the following two conditions are met: first, the drying equipment has completed the preset cleaning program, that is, the dishwasher has completed the washing and rinsing of the dishes and drained the water in the inner drum; second, the humidity sensor detects that the current humidity of the inner drum is lower than the preset humidity safety threshold. Therefore, when the control module 4 detects that the preset cleaning program has been completed and the current humidity of the inner drum is lower than the preset humidity safety threshold, it starts the discharge component 2 to perform corona discharge. Optionally, during the drying process after the discharge component 2 is started, the control module 4 continuously receives real-time humidity data of the inner tank from the humidity sensor and dynamically adjusts the duty cycle of the PWM signal based on this data, thereby achieving closed-loop control of the plasma airflow. Specifically, in the initial stage of drying, the humidity of the inner tank is high, and the control module 4 outputs a PWM signal with a high duty cycle, causing the discharge component 2 to generate strong plasma airflow, which, together with the heating module 3, forms a large flow of hot air to quickly remove moisture from the surface of the tableware. Furthermore, as the drying process progresses, the humidity of the inner tank gradually decreases, and the control module 4 correspondingly reduces the duty cycle of the PWM signal to reduce the plasma airflow, maintaining the drying effect with lower energy consumption. When the humidity of the inner tank drops to the preset drying completion threshold, the control module 4 shuts down the discharge component 2 and the heating module 3, ending the drying process.

[0036] In the above embodiments, the control module 4 determines the start-up conditions by using a humidity safety threshold and dynamically adjusts the duty cycle of the PWM signal according to the real-time humidity during the drying process. This avoids the risk of discharge failure or short circuit caused by starting the discharge component 2 in a high humidity environment, thereby improving the system's reliability and safety. At the same time, it enables on-demand supply of plasma air volume, avoiding the energy waste of traditional timed drying modes and achieving intelligent energy-saving operation.

[0037] This invention provides a drying device comprising an air duct 1, a discharge assembly 2, a heating module 3, a control module 4, and a humidity sensor. The discharge assembly 2 employs a needle-plate electrode structure coated with a superhydrophobic nano-coating 2-3. The control module 4 includes a main control board and a high-voltage drive power supply. The humidity sensor is installed inside the drying device's inner chamber to detect the inner chamber's humidity in real time and feed it back to the control module 4. The control module 4 is used to activate the discharge assembly 2 when the drying device completes a preset cleaning program and the current inner chamber humidity is below a preset humidity safety threshold. During the drying process, it dynamically adjusts the duty cycle of the pulse width modulation signal based on the real-time inner chamber humidity to regulate the plasma airflow entering the drying device. This technical solution achieves intelligent start-up of the drying process and on-demand airflow supply, significantly reducing energy consumption and improving the system's reliability and lifespan in high-humidity environments while achieving zero-noise drying. It solves the technical problems of high noise, easy failure, high energy consumption, and poor user experience associated with traditional forced-draft fan technology. The following describes a drying control method provided by an embodiment of this application, which is implemented based on the aforementioned drying equipment. Figure 3This is a flowchart illustrating a drying control method provided in an embodiment of this application. It should be noted that this specification provides the operational steps of the method as described in the embodiments or flowcharts, but based on conventional or non-inventive labor, more or fewer operational steps may be included. The order of steps listed in the embodiments is merely one possible execution order among many steps and does not represent the only execution order. In actual system or product execution, the methods shown in the embodiments or drawings can be executed sequentially or in parallel (e.g., in a parallel processor or multi-threaded processing environment). Specifically, as shown... Figure 3 As shown, the above method may include: S301: Obtain the current humidity of the inner drum after the drying equipment has completed the preset cleaning program; S303: When the current humidity of the inner chamber is lower than the preset humidity safety threshold, control the start of the discharge component and the heating module; so that the discharge component generates directional plasma wind through corona discharge, drives the outside air to flow into the drying equipment through the air duct, and is heated by the heating module to form drying hot air which is sent into the inner chamber of the drying equipment. S305: The drying process is based on hot air, and the current humidity of the inner liner is re-acquired as the real-time humidity of the inner liner during the drying process; S307: Based on the real-time humidity of the inner chamber, adjust the corona discharge intensity of the discharge component to regulate the plasma airflow entering the drying equipment; S309: If the real-time humidity of the inner chamber is not greater than the preset drying completion threshold, control the shutdown of the discharge component and heating module to stop the drying process.

[0038] In one specific embodiment, after the drying equipment completes the preset cleaning program, the control module first obtains the current humidity of the inner tank through a humidity sensor installed in the inner tank. Then, the control module compares the obtained current humidity of the inner tank with a preset humidity safety threshold: if the current humidity of the inner tank is lower than the safety threshold, it indicates that the inside of the inner tank is in a relatively dry state and the risk of water droplet adhesion is low. At this time, the control module allows the next start-up program to proceed; if the current humidity of the inner tank is still higher than the safety threshold, the control module continues to wait until the humidity drops below the safety threshold before starting. Furthermore, when the humidity inside the drying chamber is below a preset safe humidity threshold, the control module activates the discharge component and the heating module. After activation, the discharge component applies a high voltage of several thousand volts between its positive high-voltage electrode and the grounding electrode, causing a corona discharge effect at the electrode tip, ionizing the surrounding air and generating a large number of ions. These ions accelerate towards the electrode of opposite polarity under the influence of a strong electric field, colliding with a large number of neutral air molecules during their movement. Through momentum exchange, these neutral molecules move in a directional manner, forming a continuous directional plasma wind. This plasma wind drives outside air into the air duct through the air inlet, forming a drying airflow. Simultaneously, the heating module (preferably a PTC heater) heats the drying airflow, converting it into hot drying air at a certain temperature, and sends this hot drying air into the drying chamber through the air outlet. The hot drying air circulates inside the chamber, absorbing moisture from the tableware and the surface of the chamber, causing the water to evaporate into water vapor, which is then discharged outside the machine through the exhaust vents of the chamber, thus achieving the drying function. Optionally, during the drying process based on hot air, the control module continuously re-acquires the humidity of the inner liner through a humidity sensor, and uses this real-time detected humidity data as the real-time inner liner humidity. This real-time inner liner humidity reflects the actual effect of the current drying process, i.e., the dryness of the tableware and the surface of the inner liner. The humidity sensor continuously collects the inner liner humidity data at a preset sampling frequency, such as once per second or once every two seconds, and transmits it to the control module in real time. Furthermore, the control module dynamically adjusts the corona discharge intensity of the discharge component based on the real-time humidity of the inner chamber fed back by the humidity sensor, thereby regulating the plasma airflow entering the drying equipment. Specifically, the control module changes the average voltage applied to the discharge component by adjusting the duty cycle of the pulse width modulation (PWM) signal output to the high-voltage drive power supply: when the PWM signal duty cycle is high, the average voltage increases, the corona discharge intensity strengthens, and the plasma airflow speed and volume increase; when the PWM signal duty cycle is low, the average voltage decreases, and the plasma airflow decreases. Because the plasma airflow has a fast response speed and no mechanical inertia hysteresis, rapid, precise, and stepless changes in airflow can be achieved through PWM adjustment. At different stages of the drying process, the control module employs differentiated adjustment strategies: In the initial stage of drying, when the real-time humidity inside the liner is high (e.g., relative humidity above 70%), the control module outputs a PWM signal with a high duty cycle to generate a large volume of plasma air, which, together with the heating module, forms a large flow of hot air to quickly remove a large amount of moisture from the surface of the tableware; as the drying process progresses, the real-time humidity inside the liner gradually decreases, and the control module correspondingly reduces the duty cycle of the PWM signal, gradually reducing the plasma air volume to maintain the drying effect with low energy consumption; when the real-time humidity inside the liner approaches the drying completion threshold, the control module further reduces the duty cycle of the PWM signal, reducing the plasma air volume to the minimum maintenance level; Furthermore, the control module continuously compares the real-time humidity of the inner liner with the preset drying completion threshold. When the real-time humidity of the inner liner is not greater than the preset drying completion threshold, it indicates that the tableware and the surface of the inner liner have reached a sufficiently dry state and there is no need to continue drying. Then, the control module controls the shutdown of the discharge component and the heating module, stopping the drying process. At this point, a complete drying control process ends.

[0039] This invention provides a drying control method. After the drying equipment completes a preset cleaning program, the current humidity of the inner chamber is obtained. If the current humidity of the inner chamber is lower than a preset humidity safety threshold, a discharge component and a heating module are activated. The discharge component generates directional plasma air through corona discharge, driving outside air into the drying equipment via an air duct. The heating module then heats the air to form drying hot air, which is sent into the inner chamber of the drying equipment. The drying process is carried out based on the drying hot air, and the inner chamber humidity is re-obtained as the real-time humidity during the drying process. Based on the real-time humidity, the corona discharge intensity of the discharge component is adjusted to regulate the plasma airflow entering the drying equipment. If the real-time humidity of the inner chamber is not greater than a preset drying completion threshold, the discharge component and the heating module are shut down, stopping the drying process. This technical solution achieves closed-loop regulation of plasma airflow based on real-time humidity feedback. While ensuring drying effect, it achieves on-demand airflow supply, avoiding the energy waste of traditional timed drying modes. Simultaneously, the activation judgment of the humidity safety threshold effectively protects the reliability of the discharge component in high-humidity environments, improving the intelligence and energy efficiency of the drying process.
