Description

Technical Field

[0001] This invention relates to the field of dehumidifier technology, and in particular to a dehumidifier control system and a dehumidifier. Background Technology

[0002] Currently, household dehumidifiers have become a common device for improving indoor humidity. Users usually manually select the operating mode and set a desired target humidity value through the control panel. When the ambient humidity reaches the set value, the dehumidifier stops working and restarts after the humidity rises. This cycle is used to maintain a general humidity range.

[0003] However, this traditional approach has a fundamental drawback: users are often not environmental comfort experts. They are unaware of which humidity level, given the current ambient temperature, will provide optimal comfort. In reality, the comfort level perceived by the human body is the result of the combined effect of temperature and humidity; the optimal comfortable humidity varies depending on the temperature. This leads to a paradoxical situation: while users utilize dehumidifiers with adjustable functions, they often lack professional guidance to set them correctly, ultimately failing to achieve a truly comfortable environment. This significantly diminishes the device's intelligence and the user experience.

[0004] While existing technologies have attempted to optimize control through more complex sensor networks or algorithms, their core focus is often on how to more accurately execute user-defined commands or adjust wind speed and power during execution. They do not address the fundamental problem of "unscientific target humidity setting." Users are still required or assumed to provide a reasonable setting, which has become a major obstacle to improving the intelligence and user experience of dehumidifiers. Utility Model Content

[0005] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the existing dehumidifiers rely on the user's subjective setting of the target humidity, resulting in poor human comfort. It provides a dehumidification control system that can autonomously decide the optimal target humidity based on the ambient temperature, thereby fundamentally ensuring the comfort of the environment.

[0006] To solve the above-mentioned technical problems, this utility model provides a dehumidification control system, comprising: Temperature detection module, used to detect ambient temperature; The data storage module contains a first mapping table between temperature ranges and the optimal humidity for human comfort. The control module is communicatively connected to both the temperature detection module and the data storage module. The control module is configured to obtain the corresponding optimal humidity value based on the ambient temperature detected by the temperature detection module and according to the first mapping table.

[0007] In one embodiment of this utility model, a humidity detection module is further included, which is communicatively connected to the control module. The humidity detection module is used to detect the ambient humidity. The control module is also configured to: receive the ambient humidity detected by the humidity detection module, calculate the difference between the ambient humidity and the optimal humidity value, and output a control signal for controlling the operating speed of the fan and compressor based on the difference.

[0008] In one embodiment of the present invention, the fan includes a windshield control unit, which is configured to: receive the control signal and instruct the fan to increase the operating level when the difference increases and decrease the operating level when the difference decreases. In one embodiment of this utility model, the data storage module further stores a second mapping table between humidity difference and fan speed. The control module is configured to query the second mapping table based on the difference to output the corresponding wind turbine control signal.

[0009] In one embodiment of this utility model, the control module is further configured to: monitor the changing trend of the ambient humidity relative to the optimal humidity value while controlling the operation of the fan; If the trend of change is close to the optimal humidity value for human comfort, the dehumidification system and fan will continue to operate; if the trend of change is far from the optimal humidity value for human comfort, the dehumidification system and fan will stop operating.

[0010] In one embodiment of this utility model, the control module repeatedly performs signal receiving and output operations at preset time intervals to achieve dynamic fine-tuning of the optimal humidity value.

[0011] In one embodiment of this utility model, the control module is further configured to: during operation, if a change in ambient temperature is detected that causes a change in the optimal humidity value, then immediately update and output a new optimal humidity value.

[0012] To solve the above-mentioned technical problems, this utility model also provides a dehumidifier, including: a body, a dehumidification system disposed in the body and a main control board, and also including the above-mentioned dehumidification control system, wherein the dehumidification control system is integrated on the main control board; Wherein: the optimal humidity value for human perception output by the dehumidification control system is configured as the target humidity setting value of the dehumidification system.

[0013] In one embodiment of the present invention, the dehumidification system includes an evaporator, a condenser, a compressor, and a water tank, and the dehumidification system is configured to start and stop with the target of the optimal humidity value.

[0014] In one embodiment of the present invention, the dehumidifier further includes a fan system, which includes a centrifugal fan capable of adjusting different speeds.

[0015] The above-mentioned technical solution of this utility model has the following advantages compared with the prior art: The dehumidification control system and dehumidifier described in this utility model provide an innovative solution from the decision-making source. The core of this solution lies in building an intelligent dehumidification control system. Its key feature is a built-in data storage module containing a pre-stored mapping table between temperature ranges and optimal humidity for human comfort, along with a control module capable of automatically querying this mapping table. Its working principle is as follows: after the temperature detection module monitors the ambient temperature in real time, the control module actively and automatically queries the internally stored authoritative data—the first mapping table—and directly outputs the scientifically verified optimal humidity value for human comfort at the current temperature. This process requires no user intervention, guesswork, or any professional knowledge. This technical feature directly addresses the crux of existing technologies in principle. It no longer relies on potentially inaccurate or even erroneous subjective settings by the user, but instead entrusts the decision-making power for the target humidity to the system itself, based on scientific data. This is equivalent to equipping the dehumidifier with a built-in environmental comfort advisor, enabling the device to autonomously determine comfort targets and decide on the optimal target humidity based on the ambient temperature, fundamentally ensuring environmental comfort.

[0018] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0019] Reference Figure 1 As shown, this utility model provides a dehumidification control system that can automatically and intelligently determine the optimal target humidity, including a temperature detection module for detecting the ambient temperature; a data storage module, which pre-stores a first mapping table between temperature ranges and the optimal humidity for human comfort; and a control module, which is communicatively connected to the temperature detection module and the data storage module.

[0020] In this embodiment, the temperature detection module can employ a digital temperature sensor (e.g., DS18B20), an analog temperature sensor, or a temperature detection circuit integrated into other main chips. Its function is to collect the temperature data of the environment where the dehumidifier is located in real time and accurately, and transmit this data to the control module. The data storage module can be physically integrated with the control module as a non-volatile memory (e.g., Flash memory inside the MCU), or it can be an independent external storage chip (e.g., EEPROM). Its key function is to permanently store the first mapping relationship table between the temperature range and the optimal humidity for human comfort. The first mapping relationship table is a set of scientific data derived from a large number of comfort studies. Referring to Table 1, in this embodiment, the correspondence between temperature ranges and optimal humidity for human comfort is given: Table 1

[0021] Specifically, the table can exist in the form of a software lookup table, and the specific interval divisions and humidity values ​​can be adjusted and preset according to different comfort standards.

[0022] The control module is the core processing unit of the system. Its physical entity can be a microcontroller unit (MCU), a microprocessor (MPU), or a dedicated digital signal processor (DSP). The control module establishes communication connections with the temperature detection module and the data storage module through its general input / output interface or dedicated communication bus (such as I2C, SPI, UART), thereby being able to receive temperature data and access the stored data.

[0023] The control module is configured with specific control logic, which can be executed by firmware stored in memory. Its workflow is as follows: When the system is running in intelligent mode, the control module periodically or triggerably reads the current ambient temperature value from the temperature detection module. Then, it uses this temperature value as an input parameter to access and query the first mapping table in the data storage module. Through the table lookup operation, it finds the range to which the current temperature belongs and retrieves the optimal humidity value that uniquely corresponds to that range. Finally, the control module outputs this optimal humidity value as a definite value, which can be directly displayed to the user. More importantly, it provides a scientific and accurate target setpoint for the dehumidifier's subsequent humidity control loop (such as a PID controller that compares the humidity sensor feedback value).

[0024] Through the coordinated operation of the aforementioned hardware modules and specific software configuration, the dehumidification control system of this invention greatly simplifies user operation, achieving true one-button comfort. Users only need to activate the intelligent mode to obtain the optimal humidity setting guaranteed by the system, completely eliminating the confusion of selection. It significantly improves the reliability of environmental comfort. Since the target humidity is automatically generated based on the scientific correlation between temperature and humidity, it ensures that under any current temperature environment, the humidity level maintained by the dehumidifier is theoretically the most comfortable for the human body. This fundamentally avoids excessive dryness or dampness caused by improper user settings, providing users with a continuous and precise comfort experience. This effect is not achieved by improving the precision of the execution process, but by fundamentally ensuring the scientific nature of the decision-making process.

[0025] In practical applications, the dehumidification efficiency is related to the fan speed and compressor power. Therefore, the dehumidification control system in this embodiment further integrates a humidity detection module, such as a capacitive or resistive humidity sensor, to build a complete closed-loop control system for further regulating the fan speed and compressor power.

[0026] Specifically, after the humidity detection module is introduced into the system, the function of the control module is expanded. It not only outputs the optimal humidity value for human comfort, but also uses this value as a dynamic target. The control module continuously receives the current ambient humidity reported by the humidity detection module and calculates the difference between it and the target value (i.e., the optimal humidity value for human comfort) in real time. This difference directly reflects the urgency of the current dehumidification demand. Subsequently, the control module generates a signal to control the operating speed of the fan and compressor based on this difference. The fan includes a fan speed control unit, which is configured to receive the control signal to adjust the fan speed and the compressor power to obtain different wind speeds.

[0027] Specifically, its control logic is linear and intuitive: the larger the difference, the heavier the dehumidification task, and the system instructs the fan to run at a higher speed to increase the air volume and improve dehumidification efficiency; conversely, when the difference narrows and approaches the target, the fan speed is reduced.

[0028] To achieve more precise and optimized control, in this embodiment, a second mapping table is pre-stored in the data storage module. This table defines the optimal fan speed corresponding to different humidity difference ranges, as shown in Table 2. Table 2

[0029] The workflow of the control module thus becomes: first, the optimal perceived humidity value is determined by querying the first mapping table; then, the difference between the optimal perceived humidity value and the actual humidity is calculated and the second mapping table is consulted to determine the adjustment of the fan speed.

[0030] Based on the aforementioned dehumidification control system, the system can sense deviations between ambient humidity and ideal conditions and dynamically adjust fan power. When humidity is severely excessive, it provides powerful dehumidification, rapidly improving the environment; when approaching the target humidity, it operates smoothly, avoiding overshoot. By precisely matching the fan speed to real-time demand, the system avoids energy waste and continuous high noise caused by always operating at a fixed high speed, achieving the added value of energy saving and quiet operation while ensuring comfort.

[0031] Based on the above embodiments, this system further introduces trend judgment logic, which aims to solve the problem that dehumidifiers may work ineffectively or even have the opposite effect in extreme high temperature and high humidity environments.

[0032] The specific implementation of the solution is as follows: While controlling the operation of the fan, the control module will start a trend monitoring process. This process analyzes the environmental humidity data sequence reported by the humidity detection module at a preset judgment period (for example, every 3 minutes). Its core is to calculate and judge the direction and rate of change of environmental humidity in the most recent one or several periods, that is, the trend of change.

[0033] The logic for judging the changing trend is specifically configured as follows: **Approaching Trend:** If the analysis indicates that the current ambient humidity is continuously and steadily decreasing towards the optimal humidity value for human comfort, the control module determines that the dehumidification work is effective and the system is moving towards the comfort goal. In this case, the control module will maintain or optimize the current command, allowing the fan to continue running. **Declining Trend:** If the analysis indicates that the current ambient humidity has failed to decrease effectively, but instead shows an increase or remains stagnant at a high level, or that the current ambient humidity is decreasing slowly while the ambient temperature is rising rapidly, and the current temperature and humidity values ​​are moving further and further away from the most comfortable values, this usually means that factors such as the heat generated by the dehumidifier are causing the environmental conditions to deteriorate, and the dehumidification efficiency can no longer offset the negative impact. In this case, the control module will immediately generate a shutdown command, controlling the dehumidification system compressor to shut down and switching the fan system to a low speed or shutting it off, thereby ending the potentially counterproductive operating state. After the fan and compressor stop, the temperature detection module continues to work. When it detects a temperature drop, it restarts the compressor and fan to continue monitoring their changing trends.

[0034] The trend judgment logic introduced in this embodiment achieves high efficiency, energy saving, and equipment protection: the system can identify invalid working states and stop them decisively, avoiding the compressor and fan from running idle for a long time when they cannot achieve their goals, directly saving energy consumption, reducing equipment wear, and extending service life.

[0035] It fundamentally improves the user experience in extreme environments: It solves the user pain point that traditional dehumidifiers make the environment even more stuffy in hot and humid weather. By actively stopping ineffective work, it prevents the user's environment from being pushed from a high humidity state to an even more uncomfortable state with higher temperature and still high humidity, thus ensuring the user's basic comfort level.

[0036] Based on the above embodiments, this system further introduces a dynamic adjustment mechanism, enabling it to proactively adapt to changes in the environment, thereby providing continuous and precise comfort assurance.

[0037] Specifically, the system can be set to periodically wake up or execute the control process at preset time intervals (e.g., every 3 or 5 minutes). In each cycle, the control module will reread the signal from the temperature detection module and query the first mapping table again. This means that the optimal humidity value output by the system is no longer a "one-time" setting, but a dynamic target that will be updated periodically as time goes by and the ambient temperature changes.

[0038] Furthermore, the system can employ an event-triggered response mechanism. The control module continuously or frequently monitors the ambient temperature and sets a small change threshold (e.g., a temperature change exceeding 0.5°C or 1°C). Once it detects that the current temperature has changed beyond this threshold compared to the temperature at the last set target, and this change is sufficient to result in a new and different optimal humidity value after querying the first mapping table, the control module will immediately interrupt the current process, update and output this new optimal humidity value in real time, without waiting for the next preset time period.

[0039] The operation of a dehumidifier itself releases heat, which may cause the ambient temperature to rise slowly. In this embodiment, through periodic or triggered dynamic fine-tuning, the system can ensure that the target humidity always maintains a scientific match with the changing ambient temperature, solving the problem that the initial setting is accurate, but becomes uncomfortable due to temperature drift after running for a period of time, and realizing the optimization of the human experience throughout the process.

[0040] Reference Figure 2 As shown, based on the above embodiments, in order to realize the function of the dehumidification control system, this embodiment provides a dehumidifier, including: a body 10, a dehumidification system disposed in the body 10 and a main control board, and also including the above-mentioned dehumidification control system, which is integrated on the main control board; wherein: the optimal humidity value for human perception output by the dehumidification control system is configured as the target humidity setting value of the dehumidification system.

[0041] Specifically, the dehumidification system includes an evaporator 20, a condenser 30, a compressor 40, and a water tank 50. The compressor 40 drives the evaporator 20 and the condenser 30 to perform dehumidification by absorbing moisture from the air. The water tank 50 is used to collect condensate. The dehumidification system is configured to start and stop based on the optimal humidity value for human comfort. When the ambient humidity is higher than this target value, the system starts dehumidification; when the ambient humidity reaches or falls below this target value, the system stops working, thereby achieving precise control oriented towards comfort.

[0042] Specifically, the dehumidifier also includes a fan system, which includes a centrifugal fan 60 capable of adjusting different speeds to respond to airflow adjustment commands issued by the control system. Specifically, the body 10 is also equipped with a temperature sensor 70 for detecting ambient temperature and a humidity sensor 80 for detecting ambient humidity. The temperature sensor 70 and humidity sensor 80 are located at the air inlet of the body 10 to ensure that the collected environmental parameters are the most representative and undisturbed, providing an accurate data basis for the intelligent decision-making of the entire system.

Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
