Moreover, the device is portable and has the characteristics of plug-and-play after being connected to a vehicle-mounted power supply or a civilian single-phase power supply.

[0005] In order to use the vehicle power supply to produce fresh water in dry environments such as deserts, the water maker uses a semiconductor water production method. After power is turned on, the thermoelectric effect of the semiconductor causes the cold end of the semiconductor to condense water vapor in the air, which can produce drinkable fresh water in the absence of other water resources.

[0033] In conjunction with the accompanying drawings and embodiments, the technical solution of the present invention is further described in detail as follows:

[0034] In this embodiment, Figure 1As shown, a portable vehicle-mounted water making machine suitable for desert environment has an overall size (width×height×depth) of 210mm×210mm×150mm and a weight of about 1Kg. The main structure includes: a power module 1, a connector 2, a handle 3, a display circuit 4, a temperature and humidity sensor 5, a control circuit 6, a water making semiconductor 7, a fan 8, a radiator 9, a fresh water collector 10, and a water making machine housing 11.

[0035] like Figure 2 As shown, the power module 1 can adapt to DC12V, DC24V and AC220V inputs. After the DC12V voltage is input, the positive and negative poles are connected in series with diodes respectively, and the two diodes are connected in parallel to the two ends of the capacitor; after the AC220V voltage is input, a single-phase transformer and a single-phase rectifier bridge are arranged, and the output end of the rectifier bridge is connected to the two ends of the capacitor; DC12V power is provided to the control circuit, display circuit, water-making semiconductor and fan.

[0036] The connector 2 can adapt to three types of power interfaces, including a vehicle-mounted DC12V power interface, a vehicle-mounted DC24V power interface, a vehicle-mounted AC220V interface, and an interface connected to a civilian AC220V power jack. When the water maker is not in use, the cables of the connector can be arranged and placed in the water maker housing 11, and then the cover plate is closed.

[0037] The handle 3 is arranged on the top of the water making machine and can be bent to the side. After being pulled up, the water making machine can be lifted by holding the handle.

[0038] There is communication between the display circuit 4 and the control circuit 6. The control circuit 6 transmits the temperature, humidity, dew point temperature, working status of the water maker, and water production to the display circuit 4. The display circuit 4 can send the automatic to manual working mode to the control circuit 6. The control circuit 6 is in automatic working mode by default. After power-on, it automatically starts water production according to the temperature and humidity conditions. You can also operate the buttons of the display circuit 4 to change the working mode to manual. The working status of the water maker is displayed in the form of an indicator light. Other data is displayed in digital format, such as the water production is 30%. The display circuit can also display fault codes, such as E1, which means that the dew point temperature is too low and close to 0°C, and water cannot be produced.

[0039] The temperature and humidity sensor 5 is a component of the control circuit 6. The temperature and humidity sensor 5 is installed on the outside of the water making machine housing 11 to facilitate contact with the outside air. The temperature and humidity sensor 5 collects the temperature and humidity of the air near the water making machine.

[0040] The control circuit 6 also includes an analog sampling circuit, a core operation circuit, a communication circuit, an output circuit, and a photoelectric liquid level sensor. The analog sampling circuit, the core operation circuit, the communication circuit, and the output circuit are integrated on a control circuit board and installed on the top of the water making machine. The photoelectric liquid level sensor is installed on the fixed part of the fresh water collector 10.

[0041] The temperature and humidity sensor 5 and the photoelectric liquid level sensor collect information and transmit the sampling signal to the analog sampling circuit of the control circuit 6. The analog sampling circuit performs analog-to-digital conversion on the temperature and humidity and liquid level sampling signals, and sends the digital signal to the core operation circuit. The core operation circuit calculates the dew point temperature based on the table lookup and interpolation method of the air temperature and humidity, and controls the output circuit output when the water production conditions are met. The core operation circuit communicates through the communication circuit. Based on the extremely dry desert environment and the large temperature difference between morning and evening, the temperature and humidity sensor is used to accurately calculate the dew point temperature based on the current temperature and humidity, so as to achieve the use of the appropriate current size to control the water production semiconductor, achieve power saving effect and avoid unsuccessful water production.

[0042] The control circuit 6 controls the supply and disconnection of power to the water-making semiconductor 7 and the fan 8 through its output circuit, thereby starting and stopping the water-making semiconductor 7 and the fan 8.

[0043] The water-making semiconductor 7 is composed of four PN-type semiconductor modules of model 81574TZ461312-01 connected in parallel. The control circuit 6 controls the power supply of the semiconductor, and electron-hole pairs are generated near the contact point, the internal energy decreases, the temperature decreases, and heat is absorbed from the outside world, which is called the cold end. The other end increases the internal energy and temperature due to the recombination of electron-hole pairs, and releases heat to the environment, which is called the hot end. The cold end and the hot end are on the two sides of the semiconductor respectively. The hot end is directly bonded to the heat sink through silicone. The cold end and the hot end are connected to the heat sink through silicone. Figure 1 When water vapor in the air encounters the cold end of the water-making semiconductor 7, which is lower than the dew point temperature, it will condense into water on the cold end surface.

[0044] The four semiconductor modules of the water-making semiconductor 7 are laid out in a rhombus shape, the hot ends of the four semiconductor modules are glued to the radiator 9 with silicone, and the cold ends face outwards. The water-making machine housing 11 is designed as a shutter near the water-making semiconductor 7 to facilitate air inflow.

[0045] like Figure 1 As shown, the water-making semiconductor 7, the radiator 9 and the fan 8 are arranged from the outside to the inside in structure, and are used to cool the heat generated by the hot end of the water-making semiconductor 7. The fan 8 is conducive to heat dissipation and air circulation. The fan 8 is fixed on the shutter on the back of the water-making machine housing 11.

[0046] like Figure 4 As shown, the fresh water collector 10 consists of two parts, one part is fixed below the cold end of the water-making semiconductor 7 to collect water droplets condensed on the cold end surface of the water-making semiconductor 7, and the other part is detachable, and the fixed part and the detachable part are connected by an open screw.

[0047] The fixed part of the fresh water collector 10 emits light at a certain angle to the bottom of the detachable part at a fixed time, and collects the position of the reflected light from the detachable part. The signal is fed back to the control circuit 6, and the height of the liquid level and the amount of fresh water produced are calculated by monitoring the reflected light position. Figure 4 As shown, Figure 4 There is a photoelectric liquid level sensor at the interface of the water-making semiconductor in the fixed part of the fresh water collector, which can achieve the function of measuring the liquid level by releasing laser at a certain angle and monitoring the reflection position. Figure 4 (a) The collector is empty of water and light is reflected from the bottom of the removable part of the fresh water collector 10 back to the fixed part. Figure 4 (b) The collector collects half of its capacity of water, and the optical fiber is reflected from the water surface of the removable part of the fresh water collector 10 back to the fixed part.

[0048] like Figure 5 As shown, the power module of the present invention can be directly connected to a DC power supply of 12V and an AC power supply of 220V through a connector, and provide a DC power supply of 12V to the control circuit module. Figure 5 The control circuit shown completes the control of the display circuit module, the fan module and the water production module, wherein the fan module and the water production module are simultaneously controlled by the same signal of the control circuit.

[0049] The working principle of water making machine Figure 3 As shown, the connector is connected to an external power supply, and the water making machine is ready to make water; the temperature and humidity sensor reads the air temperature and humidity information, the photoelectric liquid level sensor collects the liquid level information of the fresh water collector, and then transmits the sampling signal to the analog sampling circuit in the control circuit, the analog sampling circuit performs analog-to-digital conversion processing on the temperature, humidity and liquid level sampling signals, and sends the digital signal to the core operation circuit, the core operation circuit calculates the water production amount according to the liquid level information, and calculates the dew point temperature according to the air temperature and humidity table lookup and interpolation method; if the set dew point temperature condition is not reached, the fault code E1 is displayed on the display circuit; if the water making condition is reached, the core operation circuit communicates with the display circuit via the communication circuit, the display circuit displays the current air temperature, humidity, dew point temperature, water production, working status and other information, the display circuit can send automatic or manual working mode conversion instructions to the control circuit, send water making instructions, the control circuit 6 controls the power supply and power off to the water making semiconductor 7 and the fan 8 through its output circuit, and realizes the start and stop of the water making semiconductor 7 and the fan 8. When producing water, the liquid level information is fed back through the photoelectric liquid level sensor, and the current air temperature and humidity information is fed back through the temperature and humidity sensor to determine whether to continue producing water; when the water production reaches the target liquid level, water production is stopped.
