Abstract
Description
Technical Field
[0001] This utility model belongs to the field of control and regulation technology, specifically relating to a self-adjusting temperature and humidity control system. Background Technology
[0002] With the rapid development and improvement of technology, people's demands for quality of life are also increasing. Environmental temperature and humidity have a significant impact on people's comfort. The range of temperature for which the human body feels comfortable is generally 18℃ to 25℃, and the range of relative humidity is 40% to 60%. Within this range, people usually feel most comfortable, with neither excessively dry skin and respiratory tract, nor feeling stuffy. In a sleeping environment, a slightly lower temperature (around 16℃ to 20℃) may be more conducive to falling asleep. When humidity is outside the comfortable range, such as below 40%, people may experience dry skin and respiratory discomfort. If the relative humidity is above 60%, mold and bacteria can easily grow, leading to stuffy and uncomfortable conditions.
[0003] In existing technologies, air conditioners are generally used to heat and cool the environment, while humidifiers and dehumidifiers are used to regulate ambient humidity. Some air conditioners also have dehumidification functions. However, most of these devices only have a single function, and due to the limited sensing and operating space of the devices, they usually result in uneven temperature and humidity in the same environment. The effect is usually obvious in the area near the device, while it takes a long time to be noticeable in areas far from the device. Utility Model Content
[0004] To address the problems existing in the prior art, this utility model discloses a self-adjusting temperature and humidity control system, which incorporates sensors and working elements in both the humidifier and the air conditioner, and performs linkage control through wireless transmission.
[0005] To achieve the above objectives, the technical solution of the present invention is as follows:
[0006] The self-adjusting temperature and humidity control system includes a humidifier assembly and an automatic temperature control assembly. The humidifier assembly includes a water tank, a fan, an ultrasonic transducer, and a temperature and humidity sensor. The temperature and humidity sensor is capable of wireless communication. The automatic temperature control assembly includes a controller, a temperature sensor, a compressor, and a fan motor. A heater is installed at the temperature sensor location. The heater is capable of transmitting data with the temperature and humidity sensor via wireless communication.
[0007] Furthermore, the temperature and humidity sensor is an integrated temperature and humidity sensor or includes both a temperature sensor and a humidity sensor.
[0008] Furthermore, the temperature and humidity sensor includes or is connected to a wireless communication module.
[0009] Further, the resistance value of the temperature sensor in the temperature and humidity sensor changes with the temperature. The temperature sensor is connected in series or parallel with the ultrasonic transducer, or
[0010] The humidifier assembly further includes a controller and a variable resistor. The controller of the humidifier assembly is respectively connected to the fan, the ultrasonic transducer, the controller, the variable resistor, and the temperature and humidity sensor, and has a wireless transmission function or is connected to a wireless transmission module. The controller of the humidifier assembly forms data transmission with the heater through wireless communication.

[0012] Further, the variable resistor is connected in series with the ultrasonic transducer.
[0013] Further, the variable resistor is connected in parallel with the ultrasonic transducer.
[0014] The beneficial effects of the present utility model are as follows:
[0015] The present utility model adds a heater with wireless control near the air conditioner sensor unit for temperature intervention, which can feedback the temperature at the remote humidifier to the air conditioner controller, so as to form a linkage control between the humidifier and the air conditioner without actively controlling the air conditioner. Since the temperature and humidity data are collected by the remote humidifier, the air conditioner can be controlled according to the temperature and humidity at a relatively far distance in the environment, which is beneficial to the uniformity of the environmental temperature and humidity. In addition, by using a temperature and humidity sensor or a variable resistor structure whose resistance value changes with temperature, the humidifier can adjust the working state of the ultrasonic transducer in real time, thereby adjusting the spray size. The adjustment method is flexible, and there is no need for the ultrasonic transducer itself to have an adjustable function, which saves costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The technical solution provided by this utility model will be described in detail below with reference to specific embodiments. It should be understood that the following specific embodiments are only used to illustrate this utility model and are not intended to limit the scope of this utility model.
[0023] Figure 1 This is a schematic diagram of the overall structure of the self-adjusting temperature and humidity control system, which includes a humidifier component and an automatic temperature control component. Most of the structures of each component are the same as those of existing technologies, so only the structures of the main components and the improved parts are shown.
[0024] The humidifier assembly includes a housing, a conventional water tank 1, a fan 2, an ultrasonic transducer 4, and a temperature and humidity sensor 3. The ultrasonic transducer converts water in the tank into water vapor, and the fan expels the vapor. The temperature and humidity sensor has wireless data communication capabilities and can be a separate temperature and humidity sensor, or a sensor integrating temperature and humidity data acquisition. As an improvement, the temperature sensor uses a thermocouple type, whose resistance changes with temperature. The temperature sensor is connected to the ultrasonic transducer to change the input current or voltage of the ultrasonic transducer. It should be noted that the fluctuation range of the temperature sensor's resistance value should ensure the ultrasonic transducer can operate normally; therefore, its design variation range should not affect the original ultrasonic transducer's output power by more than ±10%. It should also be noted that simply connecting the temperature sensor in series or parallel with the ultrasonic transducer is sufficient to achieve the effect of naturally adjusting the ultrasonic transducer's input current or voltage according to temperature changes. However, when using an integrated temperature and humidity sensor structure, the entire sensor is typically connected in series or parallel with the ultrasonic transducer. Figure 3 This section presents two equivalent connection methods between a temperature and humidity sensor and an ultrasonic transducer, where the ultrasonic transducer is represented by its equivalent resistance. Figure 3 (a) is a parallel connection. In this mode, the change in the resistance of the temperature sensor can change the overall resistance of the original ultrasonic transducer, thereby changing the actual operating current of the ultrasonic transducer and thus changing the spray size. Figure 3 (b) In the series configuration, the temperature sensor has a wider resistance range, which can change the voltage across the ultrasonic transducer, thereby altering the actual operating voltage of the ultrasonic transducer and thus the spray size. The series configuration uses a Honeywell TD series temperature sensor, whose resistance increases with temperature, making it suitable for series connection with the ultrasonic transducer. It should be noted that the ultrasonic transducer is inside the water tank, while the temperature and humidity sensors are outside the water tank, monitoring the ambient temperature and humidity at the humidifier location. Figure 4 The humidifier diagram shows the location of the ultrasonic transducer, where the fan position can be adjusted as needed. Figure 1 They are different. Temperature data collected by the temperature sensor or temperature and humidity sensor is synchronized to the heater in the automatic temperature control component via wireless communication. A model with built-in wireless communication functionality can be used, or the temperature and humidity sensor can be connected to a separate wireless communication module.
[0025] As an improvement, such as Figure 5 As shown, we can also include a controller 6, an adjustable resistor 5, and a wireless transmission module 12 in the humidifier assembly. The controller, as the main control component of the humidifier, is connected to the fan and ultrasonic transducer. The adjustable resistor and temperature and humidity sensors are connected to the controller. Based on changes in data collected by the temperature and humidity sensors, the controller adjusts the resistance value of the adjustable resistor, thereby controlling the spray pattern. Figure 4 As shown, in the parallel connection of the adjustable resistor and the ultrasonic transducer, changing the resistance value of the adjustable resistor alters the overall resistance value of the ultrasonic transducer, thereby changing the actual operating current of the ultrasonic transducer and thus changing the spray size. In the series connection of the adjustable resistor and the ultrasonic transducer, a high-power adjustable resistor with a wide resistance range should be used to change the voltage across the ultrasonic transducer, thereby changing the actual operating voltage and thus the spray size. In this method, the temperature and humidity sensor does not need to have communication functionality, so it can be replaced with more types and models of temperature and humidity sensors. Alternatively, temperature and humidity sensors can be used separately. The controller establishes a data connection with the heater in the automatic temperature control component via a wireless transmission module; alternatively, a controller with a built-in wireless transmission module can also be used.
[0026] The automatic temperature control assembly includes a housing and a conventional controller 6, temperature sensor 7, compressor 8, fan motor 9, damper 10, and condenser. It also includes a heater 11 and a wireless transmission module. The controller connects to the temperature sensor, compressor, fan motor, and damper, receiving data from the temperature sensor and controlling their operation. The heater communicates wirelessly with the humidifier, maintaining temperature synchronization directly with the temperature sensor in the temperature and humidity sensor, or is controlled by the controller within the humidifier. The heater is placed close to the temperature sensor in the automatic temperature control assembly to change the temperature in the vicinity. The heater can affect the ambient temperature by increasing or decreasing it by 10°C at a distance of approximately 1 cm. In this example, the heater is a Honeywell YTH6320R1001. The heater can be connected to the wireless transmission module or use a heater with a built-in wireless transmission module.
[0027] The workflow of this utility model is as follows:
[0028] Since uncomfortable indoor environments are primarily characterized by high temperature and high humidity or low temperature and low humidity, this invention cleverly utilizes the resistance change characteristic of a thermocouple-type temperature sensor with temperature variations. By connecting this sensor to an ultrasonic transducer, the spray volume can be adjusted. During operation, the temperature and humidity sensor at the humidifier end collects humidity and temperature data from the vicinity of the humidifier. Taking the sensor and ultrasonic transducer in series as an example, when excessive humidity or temperature is detected, the sensor resistance increases, the ultrasonic transducer input current decreases, and the humidifier's mist output decreases. The temperature data collected by the temperature and humidity sensor is synchronized wirelessly to the heater in the automatic temperature control component. The heater then operates, raising the temperature to match the temperature data collected by the humidifier's temperature and humidity sensor. This raises the ambient temperature around the temperature sensor in the automatic temperature control component, which then automatically initiates cooling. When excessively low temperature or humidity is detected, the sensor resistance decreases, the ultrasonic transducer input current increases, and the humidifier's mist output increases. The temperature data collected by the temperature and humidity sensor is synchronized to the heater in the automatic temperature control component via wireless communication. The heater stops working and lowers its temperature to match the temperature data collected by the temperature and humidity sensor in the humidifier. The ambient temperature around the temperature sensor in the automatic temperature control component decreases, and the automatic temperature control component automatically starts heating.
[0029] like Figure 6 As shown, when a humidifier uses a controller and adjustable resistor, more precise control is possible. The humidifier and the automatic temperature control component (air conditioner) can operate independently and are located in different areas of the room. The humidity sensor at the humidifier end collects humidity and temperature data near the humidifier. When excessive humidity is detected, for example, greater than 60%, the adjustable resistor at the humidifier end increases (in the case of adjustable resistors in series), the input current of the ultrasonic transducer decreases, and the humidifier's water mist output decreases. When excessive humidity is detected, for example, less than 18%, the adjustable resistor at the humidifier end decreases (in the case of adjustable resistors in series), the input current of the ultrasonic transducer increases, and the humidifier's water mist output increases. When the humidity is within a suitable range, it checks whether the temperature is too high. If it is, it synchronously controls the heater to operate via wireless transmission, raising the temperature to match the temperature data collected by the humidifier's humidity sensor. The heater raises the ambient temperature around the temperature sensor in the automatic temperature control component, and the automatic temperature control component automatically starts the cooling process. When the temperature is too low, the controller synchronously controls the heater to stop working or cool down to the same temperature as the temperature data collected by the humidifier's temperature and humidity sensor via wireless transmission. When the ambient temperature around the temperature sensor in the automatic temperature control component decreases, the automatic temperature control component automatically starts the heating operation.
[0030] During operation, this utility model only requires the use of general software embedded in the controller for relevant settings, or basic settings in the temperature and humidity sensor. Since it only needs to implement simple data transmission and threshold judgment functions, no innovative improvements to the software are required.
[0031] It should be noted that the above content merely illustrates the technical concept of this utility model and cannot be used to limit the scope of protection of this utility model. For those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and all such improvements and modifications fall within the scope of protection of the claims of this utility model.
