It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and the protection scope of the present invention is not limited to the following specific embodiments.

[0052] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the said features.

[0053] See also Figure 1The present invention provides a semiconductor condensation water extraction device, comprising a shell 1, a semiconductor refrigeration plate 2 and a control unit 3, wherein the shell 1 is provided with an air inlet and an air outlet, and a water collecting tank 11 for collecting condensed water is provided in the shell 1, the semiconductor refrigeration plate 2 is arranged in the shell 1 and is located above the water collecting tank 11, and the cooling surface of the semiconductor refrigeration plate 2 faces the water collecting tank 11, so that the condensed water can fall into the water collecting tank 11 for collection, the semiconductor refrigeration plate 2 divides the interior of the shell 1 into an upper heating chamber and a lower condensing chamber, the air inlet is connected to the heating chamber, the air outlet is connected to the condensing chamber, and the heating chamber and the condensing chamber are interconnected, so that the air can first flow through the heating chamber after entering the shell 1 from the air inlet and then enter the shell 1. The air is heated and then enters the condensation chamber to realize condensation, so that the air flowing through the heating chamber can be heated by the heat dissipation surface of the semiconductor refrigeration plate 2, so that when the ambient temperature is below 0 degrees Celsius, the air passing through the heating chamber can be heated to above 0 degrees Celsius and then condensed, so that condensation and water extraction can be realized in a low-temperature environment. The control unit 3 is communicated with the semiconductor refrigeration plate 2 to control the temperature of the semiconductor refrigeration plate 2, so that the temperature of the semiconductor refrigeration plate 2 can be controlled by the control unit 3, so that the temperature difference between the heat dissipation surface and the cooling surface is within a set range, so as to realize efficient condensation and water extraction, so as to realize the utilization of the heat of the heat dissipation surface of the semiconductor refrigeration plate 2, so that the power consumption of condensation and water extraction is low.

[0054] It is understandable that the semiconductor refrigeration plate 2 needs to be connected to a power source, which can be a solar photovoltaic power supply device or a power grid. The shell 1 can be made of an acrylic plate to facilitate cleaning and make the entire semiconductor condensation and water extraction device light and easy to carry.

[0055] Specifically, in order to achieve automatic control of the temperature of the semiconductor refrigeration plate 2, the semiconductor condensation water extraction device provided in the first aspect of the present invention also includes: a detection unit 4, which can be specifically configured to include a temperature and humidity sensor 41 arranged at the air inlet, a first temperature sensor 42 arranged in the heating chamber close to one end of the condensation chamber, and a second temperature sensor 43 arranged on the refrigeration surface, so that the ambient temperature and ambient humidity can be obtained through the temperature and humidity sensor 41, the temperature to which the air is heated before condensation can be obtained through the first temperature sensor 42, and the temperature on the refrigeration surface can be obtained through the second temperature sensor 43. The temperature and humidity sensor 41, the first temperature sensor 42 and the second temperature sensor 43 are all communicatively connected to the control unit 3, so as to be suitable for receiving signals from the temperature and humidity sensor 41, the first temperature sensor 42 and the second temperature sensor 43 and to control the temperature of the semiconductor refrigeration plate 2 accordingly.

[0056] For details, see Figure 2 and Figure 3The condensation water extraction control method provided by the present invention is as follows: obtain the ambient temperature. If the ambient temperature detected by the temperature and humidity sensor 41 is lower than 0°C, the control unit 3 controls the semiconductor refrigeration plate 2 to operate at the highest voltage to maintain the refrigeration temperature of its refrigeration surface at 0°C, and controls the semiconductor refrigeration plate 2 so that the heat dissipation temperature of the heat dissipation surface can make the temperature of the air flowing from the heating chamber to the condensation chamber greater than or equal to 10°C (it can be understood that the temperature of the air may not reach the temperature of the heat dissipation surface after the heat exchange between the air and the heat dissipation surface. Therefore, the first temperature sensor 42 is used to measure the temperature of the air coming out of the end of the heating chamber close to the condensation chamber to more accurately determine the air temperature), so that condensation water extraction can be achieved in a low temperature environment, and it is ensured that the condensed water will not freeze and adhere to the refrigeration surface to reduce the condensation effect.

[0057] If the ambient temperature detected by the temperature and humidity sensor 41 is greater than or equal to 0°C and less than 10°C, the control unit 3 can be used to control the semiconductor refrigeration plate 2 to operate at the optimal condensation efficiency voltage, so that the temperature difference between the temperature of the air when it flows from the heating chamber to the condensing chamber and the refrigeration temperature is greater than or equal to the set value, and the set value is greater than or equal to 10°C. For example, the refrigeration temperature of the refrigeration surface can be set to be greater than or equal to 0°C and less than 10°C, and the specific refrigeration temperature can be determined based on the ratio of the power consumption at the refrigeration temperature to the collection speed of condensed water. The smaller the ratio, the lower the power consumption of collecting unit volume of condensed water, and the refrigeration temperature is set to the preferred temperature.

[0058] If the ambient temperature detected by the temperature and humidity sensor 41 is greater than 10°C, the control unit 3 can control the semiconductor refrigeration plate 2 to operate at the best condensation efficiency voltage and maintain the refrigeration temperature at 0°C to obtain the fastest condensed water collection speed.

[0059] Furthermore, a water outlet needs to be connected to the water collecting tank 11, and the water collecting tank 11 can be connected to an irrigation system or a household water device through the water outlet for easy use. A water outlet valve 111 is provided at the water outlet. The detection unit 4 also includes a liquid level sensor 44 arranged in the water collecting tank 11. The liquid level sensor 44 is suitable for detecting the liquid level in the water collecting tank 11. For example, an infrared distance sensor can be used as the liquid level sensor 44. The infrared distance sensor is arranged on the upper part of the water collecting tank 11 and detects the distance between the liquid surface and the liquid level sensor 44. The infrared distance sensor and the water outlet valve 111 are both connected to the control unit The control unit 3 is connected to the element 3 for communication, and the control unit 3 is suitable for receiving the signal of the liquid level sensor 44 and controlling the opening and closing of the water outlet valve 111. For example, when the infrared distance sensor detects that the distance between the liquid surface and itself is less than or equal to the set value (for example, 10 mm), it means that the water collecting tank 11 is full, and the control unit 3 controls the water outlet valve 111 to open to discharge the water in the water collecting tank 11, until the infrared distance sensor detects that the distance between the liquid surface and itself is greater than or equal to the set value (for example, 200 mm), it means that the water in the water collecting tank 11 is basically emptied, and the control unit 3 controls the water outlet valve 111 to close for the next round of water collection.

[0060] It can be understood that an air intake turbine 5 and an air filter 6 can be provided at the air inlet. Specifically, a temperature and humidity sensor 41, an air intake turbine 5 and an air filter 6 are provided in sequence from the air intake to the top. The temperature and humidity sensor 41 is arranged at the front end for the convenience of realizing accurate monitoring of the ambient temperature and humidity. The air filter 6 can specifically include a filter element and an ultraviolet disinfection lamp, so that solid impurities in the air can be filtered out by the filter element, and bacteria, viruses, etc. in the air can be killed by the ultraviolet disinfection lamp, so that the collected condensed water has higher water quality and is convenient for home use.

[0061] In addition, an exhaust turbine 7 is also provided at the air outlet, and both the intake turbine 5 and the exhaust turbine 7 can be connected to the control unit 3 for communication, so that the speed of the intake turbine 5 and the exhaust turbine 7 can be controlled by the control unit 3. Specifically, the condensation water intake control method provided by the present invention is to adjust the speed of the intake turbine 5 and the exhaust turbine 7 according to the ambient humidity obtained by the temperature and humidity sensor 41. For example, when the air humidity is less than or equal to 50% RH, the intake turbine 5 and the exhaust turbine 7 rotate at a speed of V1, and when the air humidity is greater than 50% RH, the intake turbine 5 and the exhaust turbine 7 rotate at a speed of V2. Among them, V1 is greater than V2, and the speed of the turbine can be more finely controlled according to the air humidity. The control rule is: when the ambient humidity increases, the speed of the intake turbine 5 and the exhaust turbine 7 is controlled to decrease, so that the speed of air flowing through the semiconductor refrigeration plate 2 is reduced, so that the water vapor in the air can be fully condensed to reduce energy consumption; when the ambient humidity decreases, the speed of the intake turbine 5 and the exhaust turbine 7 is controlled to increase, so that the speed of air flowing through the semiconductor refrigeration plate 2 is increased, that is, more air can flow through the semiconductor refrigeration plate 2 per unit time, thereby ensuring the condensation and water extraction rate.

[0062] It can be understood that a condensation plate 21 can be arranged on the cooling surface of the semiconductor refrigeration plate 2, and a guide plate 12 can be arranged between the cooling surface of the semiconductor refrigeration plate 2 and the water collecting tank 11, so that the heated air can flow between the semiconductor refrigeration plate 2 and the guide plate 12, so that the heated air can be closer to the cooling surface of the semiconductor refrigeration plate 2, thereby having a good condensation effect. The condensation plate 21 can be made of an aluminum plate, and a heat dissipation fin can be arranged on the side of the condensation plate 21 facing the guide plate 12, and the extension of the heat dissipation fin The extension direction is consistent with the flow direction of the air, so as to increase the heat exchange area and improve the condensation effect, which is more suitable for condensation and water collection in arid places. The guide plate 12 is arranged inclined to the horizontal plane, and the water outlet end of the guide plate 12 is above the water collecting tank 11, so that the condensed water dripping onto the guide plate 12 can enter the water collecting tank 11 under the guiding effect of the guide plate 12, so that the water collecting tank 11 only needs to set an opening at the water outlet end of the guide plate 12 for receiving water, which can reduce the evaporation of water in the water collecting tank 11.

[0063] In addition, in order to increase the speed of condensation and water extraction, a large-sized semiconductor refrigeration plate 2 can be used or multiple semiconductor refrigeration plates 2 can be assembled into a large refrigeration plate, and the width of the heating cavity and the refrigeration cavity can be expanded so that more air can contact the semiconductor refrigeration plate 2 per unit time.

[0064] Furthermore, the semiconductor condensation water extraction device provided by the present invention also includes an interactive device 8, which can be a touch screen display. The touch screen display can be communicated with the temperature and humidity sensor 41, the first temperature sensor 42, the second temperature sensor 43, the liquid level sensor 44, the semiconductor refrigeration plate 2 and the control unit 3 through the 5G signal network, so that the temperature and humidity information detected by the temperature and humidity sensor 41, the temperature information detected by the first temperature sensor 42 and the second temperature sensor 43, the liquid level information detected by the liquid level sensor 44 and the temperature information of the cooling surface of the semiconductor refrigeration plate 2 can be displayed on the touch screen display, which is convenient for users to monitor in real time, and control instructions can also be input on the touch screen display, so that the control unit 3 executes the corresponding control instructions when receiving the control instructions, for example, controlling the water outlet valve 111 to be normally open as needed to facilitate timely water extraction.

[0065] The present invention also provides a storage medium, on which a computer program is stored. When the computer program is run by a processor, the condensation water intake control method in the above-mentioned technical solution is executed. Since the computer program executes the condensation water intake control method in the above-mentioned technical solution when the processor is run, it also has all the technical effects of the above-mentioned condensation water intake control method.

[0066] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, a variety of simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0067] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0068] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
