Description

Technical Field

[0001] The invention relates to a device for extracting water by condensation from air, in particular to a device for extracting water by condensation from air for producing condensed water for drinking. Background Art

[0002] In addition to breathing, the most important thing to maintain human life is water. Without drinking water, people cannot survive. If they drink unsanitary water, they are prone to infection with diseases.

[0003] In remote areas of some backward and poor countries, the lack of water and electricity infrastructure, especially the lack of clean drinking water, will lead to a lot of diseases and seriously affect people's health. However, most of these backward countries cannot build a tap water supply system because the government finances cannot afford it. Therefore, how to provide simple and effective water production equipment has become a quick way to effectively improve backward areas.

[0004] In addition, when people engage in outdoor sports, if they go to the wilderness or the sea, they are prone to dehydration if they lack water. Therefore, when people engage in activities such as mountaineering, hiking, or sailing, they must reserve sufficient drinking water, which creates a burden for people. Therefore, how to provide a simple and portable water-making device has become a feasible way to overcome the risk of water shortage in outdoor activities.

[0005] However, existing water making machines or water making devices are usually quite large in size, complex in structure, and expensive, so they cannot be popularized to households in backward areas. In addition, existing water making machines can only be used in a fixed manner and cannot be provided to outdoor sports people for carrying and use. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide a device for condensing water from the air in view of the shortcomings of the existing water making machine technology.

[0007] In order to solve the above-mentioned technical problems, one of the technical solutions adopted by the present invention is to provide a device for condensing water from the air, which includes: a water-making device, a container connected to the lower end of the water-making device, and an electric power supply device; the water-making device is configured to be able to inhale air from the surrounding environment, condense the moisture in the air into water, and then flow into the container for storage; wherein, the water-making device includes: a shell, the shell has a accommodating portion inside, the shell has a water outlet end located below the shell, and an air inlet and an exhaust port; a cooling chip is arranged in the accommodating portion of the shell; a condensing module is arranged at the cold end of the cooling chip; a heat dissipation module is arranged at the hot end of the cooling chip; and a control circuit, the control circuit includes a microcontroller, and a power controller coupled to the cooling chip, and an environmental humidity sensor, an environmental temperature sensor, and a cold end temperature sensor; wherein, The air outside the water-making device passes through the inside of the shell and contacts the condensing module. The cold end of the refrigeration chip absorbs the heat energy of the air entering the inside of the shell through the condensing module, so that the moisture in the air condenses into condensed water. The control circuit of the water-making device is configured to detect the ambient humidity and ambient temperature around the water-making device through the ambient humidity sensor and the ambient temperature sensor, and control the water-making device to start operation only when the ambient humidity is greater than a humidity critical value and the ambient temperature is within an effective operating temperature range. In addition, the control circuit is configured to detect the temperature of the cold end of the refrigeration chip or the surrounding area adjacent to the cold end of the refrigeration chip through the cold end temperature sensor, and adjust the power of the refrigeration chip during operation through the microcontroller, the cold end temperature sensor and the power controller, so as to control the temperature of the cold end of the refrigeration chip.

[0008] One of the beneficial effects of the present invention is that the device for condensing water from the air provided by the present invention sets a heat dissipation module at the hot end of the cooling chip and sets a condensation module at the cold end, so that the cold end of the cooling chip can absorb the heat energy of the air through the condensation module, and the moisture in the air condenses into condensed water, and dissipates heat through the heat dissipation module, so that when the cooling chip produces condensed water, the temperature of the hot end can be lowered through the heat dissipation module, so that the cooling chip will not overheat, and the condensation module can maintain good water production efficiency for a long time.

In addition, the term "or" used in this article may include any one or more combinations of the associated listed items depending on the actual situation.

[0015] [First embodiment]

[0016] See also Figures 1 to 3As shown, an embodiment of the present invention provides a device 1 for extracting water by condensation from air, which includes: a water making device 100, a container 300, a filter module 200, and a power supply device 400. The filter module 200 and the container 300 are connected to the lower end of the water making device 100, and the power supply device 400 is used to generate electricity and supply it to the water making device 100. The water making device 100 condenses the moisture in the air into water through condensation. The water produced by the water making device 100 is filtered by the filter module 200 to become drinkable water, and then flows into the container 300 for storage for users.

[0017] like Figure 1 and Figure 2 As shown, the water making device 100 has a housing 110, a cooling chip 120, a heat dissipation module 130, and a condensing module 140. The housing 110 has a receiving portion 111 formed inside, a water outlet is formed at the lower end of the housing 110, and a plurality of air inlets 112 are provided, and an exhaust port 113 is provided at the upper end of the housing 110. A display unit 150 and a plurality of buttons 151 are also provided on the outer side of the housing 110, which are used to display the operation information of the water making device 100 and for the user to input the operation instructions of the water making device 100.

[0018] The display unit can be composed of a variety of different types of display components, such as: LCD or TN display panel, LED display, OLED display, or composed of multiple LED light-emitting components. The information that can be displayed by the display unit includes: temperature, humidity, battery power, water production speed, water level and other information. In addition, the display unit can also provide the operator with various operating parameters for setting the water production device 100. For example: setting the startup temperature and humidity of the cooling chip 120; or setting the operating temperature range and humidity after the cooling chip is started.

[0019] The cooling chip 120 is generally in the shape of a flat plate, and the two opposite sides of the cooling chip 120 can define a cold end and a hot end. In this embodiment, the cooling chip 120 is arranged in the receiving portion 111 of the housing 110 in a manner that the cold end faces downward and the hot end faces upward. When current passes through the cooling chip 120, it can absorb heat energy from the cold end and release heat energy from the hot end, so that the temperature of one side of the cold end of the cooling chip 120 decreases, while the temperature of the hot end increases.

[0020] The heat dissipation module 130 is disposed at the hot end of the cooling chip 120 to dissipate heat from the hot end of the cooling chip 120. In this embodiment, the heat dissipation module 130 includes a hot end heat conducting plate 131 that is substantially plate-shaped, a plurality of heat sinks 132 disposed on a side of the hot end heat conducting plate 131 that is opposite to the cooling chip 120, and a circulation fan 133 disposed above the accommodating portion 111 of the housing 110 and adjacent to the exhaust port 113. The hot end heat conducting plate 131 is substantially flat, one side of the hot end heat conducting plate 131 contacts the hot end of the cooling chip 120, and the other side is provided with a plurality of heat sinks 132. The heat energy released from the hot end of the cooling chip 120 can be conducted to the hot end heat conducting plate 131, and then to the plurality of heat sinks 132. The airflow generated by the circulation fan 133 can pass through the plurality of heat sinks 132, so that the temperature of the hot end of the cooling chip 120 can be released into the air through the plurality of heat sinks 132, so as to avoid the situation where the temperature of the cooling chip 120 is too high and the water production efficiency of the water production device 100 is reduced.

[0021] In more detail, in this embodiment, the hot end heat conducting plate 131 of the heat dissipation module 130 can be a plate made of a heat conducting material (such as copper, aluminum), or can be a temperature equalizing plate, so that the heat energy of the cooling chip 120 can be quickly transferred to various positions of the hot end heat conducting plate 131. The plurality of heat sinks 132 can be honeycomb heat sinks. Since the heat sink 132 is in a honeycomb structure, a plurality of channels for heat dissipation airflow are formed. In addition, the heat sink 132 is arranged above the hot end of the cooling chip 120, so that the hot air flow can pass through the airflow channel of the heat sink 132 when flowing upward. Therefore, when the airflow passes through the plurality of airflow channels inside the heat sink 132, a chimney effect is generated, thereby improving the heat dissipation efficiency of the heat sink 132.

[0022] The condensing module 140 is arranged at the cold end of the refrigeration chip 120. In this embodiment, the condensing module 140 includes a plate-shaped cold end heat conducting plate 141, a plurality of conducting members 142 arranged on the side of the cold end heat conducting plate 141 opposite to the refrigeration chip 120, and a plurality of fins 143 arranged on each conducting member 142. The cold end heat conducting plate 141 contacts the cold end of the refrigeration chip 120, the plurality of conducting members 142 are generally columnar, the upper end of each conducting member 142 is connected to the surface of the cold end heat conducting plate 141, and the plurality of conducting members 142 are spaced apart from each other so that airflow can pass through the plurality of conducting members 142. The conducting member 142 can be a column made of a heat conducting material (such as copper, aluminum), or a heat pipe can be used to improve the heat conduction efficiency, and each conducting member 142 is also provided with a plurality of fins.

[0023] When the air contacts the surfaces of the cold end heat conducting plate 141, the conductive member 142 and the fins 143, the temperature of the air can be reduced, so that the moisture in the air forms water droplets, which condense on the surfaces of the cold end heat conducting plate 141, the conductive member 142 and the fins 143, and then the condensed water droplets drip into the filter module 200 and the container 300 due to gravity.

[0024] It is particularly noted that in this embodiment, a partition 114 is provided on the inner side of the shell 110 corresponding to the position of the refrigeration chip 120 and the condensation module 140, dividing the accommodating portion 111 into an upper portion and a lower portion. The cold end heat conducting plate 141 of the refrigeration chip 120 and the condensation module 140 is supported by the partition 114, the heat dissipation module 130 is located in the space above the high partition 114 in the accommodating portion 111, and the condensation module 140 is located in the space below the partition 114 in the accommodating portion 111. In addition, a plurality of flow gaps 1141 surrounding the refrigeration chip 120 and the periphery of the water making device 100 are formed on the partition 114, so that the airflow in the space below the partition 114 can flow to the space above the partition 114 through the plurality of flow gaps 1141.

[0025] Therefore, in this embodiment, when the circulation fan 133 is running, it can drive the airflow to enter from the air inlet 112, pass through the condensing module 140, enter the space above the partition 114, pass through the heat sink 132, and then be discharged from the exhaust port 113. Therefore, the air entering the housing 110 from the air inlet 112 first contacts the condensing module 140 for cooling, and then contacts the heat sink 132 of the heat sink module 130, thereby improving the heat dissipation efficiency of the cooling chip 120 and saving power consumption.

[0026] like Figure 2 and Figure 3 As shown, the power supply device 400 is used to supply the power required for the operation of the water production device 100. The power supply device 400 includes: a thin-film solar charging panel 410, an inertial power generation device 420, a battery 430, and a charge and discharge controller 440.

[0027] Among them, Figure 2As shown, the thin-film solar charging panel 410 can be arranged on the outer side of the housing 110 of the water-making device 100 to convert the light energy of the sun's rays into electrical energy. The charge-discharge controller 440 and the battery are coupled to the thin-film solar charging panel 410, so that the current generated by the thin-film solar charging panel 410 can charge the battery 430. In addition, in this embodiment, the power supply device 400 can also include an inertial power generation device 420, which has an inertial motion part (such as a steering flywheel or an inertial slider for linear motion) and a micro-power generation device linked to the inertial motion part. When the water-making device 100 is displaced, the micro-power generation device can be driven by the inertial motion part to generate electricity, thereby converting kinetic energy into electrical energy.

[0028] The power supply device 400 can generate power to supply the water production device 100, so that the device 1 for extracting water from air by condensation does not need to be supplied by the mains electricity and can be used in the wild or remote areas without power supply.

[0029] like Figure 3 As shown, the control circuit of the water production device 100 of the present invention includes: a microcontroller 510 , a comparison circuit 520 , a power controller 530 , a fan controller 540 , and a sensor module 550 .

[0030] The sensor module 550 further includes: an environmental humidity sensor 551, an environmental temperature sensor 552, a cold end temperature sensor 553, a hot end temperature sensor 554, and a water level sensor 555. The environmental humidity sensor 551 and the environmental temperature sensor 552 are arranged outside the water making device 100, or are arranged inside the housing 110 at a position adjacent to the air inlet 112. The environmental humidity sensor 551 and the environmental temperature sensor 552 are used to detect the humidity and temperature of the external environment of the water making device 100, respectively.

[0031] The cold end temperature sensor 553 and the hot end temperature sensor 554 are respectively disposed in the accommodating portion 111 of the housing 110 , and are respectively used to detect the cold end and the hot end of the cooling chip 120 , or to detect the temperature of the area around the cold end and the hot end inside the housing 110 .

[0032] The environment humidity sensor 551 , the environment temperature sensor 552 , the cold end temperature sensor 553 , and the hot end temperature sensor 554 are coupled to another input terminal of the comparison circuit 520 .

[0033] The microcontroller 510 is coupled to the ambient humidity sensor 551, the ambient temperature sensor 552, the cold end temperature sensor 553, and the hot end temperature sensor 554 through the comparison circuit 520, and is coupled to the cooling chip 120 through the power controller 530, and is coupled to the circulation fan 133 through the fan controller 540, and is coupled to the water level sensor 555.

[0034] When the water-making device 100 is operating, the microcontroller 510 can further cooperate with the power controller 530 and the fan controller 540 to control the operation of the cooling chip 120 and the circulation fan 133 based on the cold-end temperature of the cooling chip detected by the cold-end temperature sensor 553, the ambient temperature detected by the ambient temperature sensor 552, and the hot-end temperature of the cooling chip 120 detected by the hot-end temperature sensor 554, so as to maintain the water-making device 100 operating in the optimal state.

[0035] The following further describes the method and steps of the microcontroller 510 controlling the operation of the cooling chip 120 and the circulation fan 133 to maintain the water making device 100 to make water under the optimal conditions.

[0036] First, the microcontroller 510 is configured to start the water-making device 100 only when the ambient temperature is between an effective operating temperature range (for example, 8°C to 40°C) and the ambient humidity is greater than a humidity threshold value (for example, 40% RH), so as to avoid the situation where the water-making device 100 cannot condense water from the air due to the ambient humidity being too low or the ambient temperature being too low or too high, causing the water-making device 100 to idle and waste energy.

[0037] When the water making device 100 is running, the comparison circuit 520 can compare the temperature of the cold end of the cooling chip 120 with the ambient temperature detected by the ambient temperature sensor 552 to obtain the difference between the cold end temperature and the ambient temperature, and the microcontroller 510 can further control the operating power of the cooling chip 120 according to the difference between the cold end temperature and the ambient temperature and the cold end temperature of the cooling chip 120.

[0038] When the water production device 100 is running, the microcontroller 510 is configured to be able to detect the cold end temperature of the cooling chip 120 through the cold end temperature sensor 553, and cooperate with the power controller 530 to adjust the power or pulse frequency of the current supplied to the cooling chip 120 to control the operating temperature of the cooling chip 120 to maintain it within the temperature range that can effectively produce water.

[0039] In one embodiment of the present invention, the effective water production temperature range of the cooling chip 120 is between 0°C and 5°C, so that the temperature of the cold end of the cooling chip 120 is maintained within the temperature range that can condense the moisture in the air into water droplets, avoiding the formation of frost or ice, or the cold end temperature is higher than the lowest temperature (dew point) at which the moisture in the air can condense into water droplets. When the temperature of the cold end of the cooling chip 120 is close to 0°C, the microcontroller 510 can reduce the power or pulse frequency of the current of the cooling chip 120 so that the temperature of the cold end of the cooling chip 120 will not continue to drop. When the temperature of the cold end of the cooling chip 120 is close to 5°C, the power controller 530 is controlled to increase the power or pulse frequency of the current of the cooling chip 120 to reduce the temperature of the cold end of the cooling chip 120.

[0040] In one embodiment of the present invention, the microcontroller 510 is further configured to control the power and temperature of the cooling chip 120 according to the difference between the cold end temperature of the cooling chip 120 and the ambient temperature, in combination with the ambient humidity. For example, when the ambient temperature is close to the cold end temperature of the cooling chip 120, the power controller 530 can be used to control the power or pulse frequency of the current of the cooling chip 120, so that the cold end temperature of the cooling chip 120 decreases, and the difference between the cold end temperature and the ambient temperature is increased to improve the efficiency of condensation water production. When the difference between the ambient temperature and the cold end temperature of the cooling chip 120 is large, the current power or pulse frequency of the cooling chip 120 can be controlled to decrease, so that the cooling speed of the cooling chip 120 is slowed down. In this state, since the cold end temperature of the cooling chip 120 is large different from the ambient temperature, the cooling chip 120 can operate at a lower power, and energy consumption can be saved.

[0041] In addition, in the present embodiment, the microcontroller 510 also uses the hot-end temperature sensor 554 and the cold-end temperature sensor 553 to detect the difference between the hot-end temperature and the cold-end temperature of the cooling chip 120 to control the speed of the circulation fan and the power of the cooling chip 120. For example, when the difference between the hot-end temperature and the cold-end temperature of the cooling chip 120 is large, the microcontroller 510 can control the speed of the circulation fan 133 to increase through the fan controller 540 to increase the heat dissipation efficiency, so that the hot-end temperature of the cooling chip 120 is reduced, and the temperature of the hot end of the cooling chip 120 is prevented from being too high, causing the temperature to be transmitted to the cold end of the cooling chip 120, resulting in a decrease in the water production efficiency of the cooling chip 120 and an increase in power consumption.

[0042] Furthermore, when the speed of the circulating fan 133 has reached a limit and the cold end temperature of the cooling chip 120 is affected by the hot end temperature and cannot be reduced, the microcontroller 510 can control the current power or pulse frequency of the cooling chip 120 to reduce the operating power of the cooling chip 120, thereby preventing the hot end temperature from continuing to rise and causing the temperature to be transmitted to the cold end, resulting in the evaporation of condensed water droplets.

[0043] Next, the technical features of the filter module 200 and the container 300 are introduced.

[0044] In this embodiment, the filter module 200 has a filter housing 240, and the upper and lower ends of the filter housing 240 respectively have a first connecting portion 241 and a second connecting portion 242. The first connecting portion 241 can be detachably connected to the lower end of the water production device 100, and the second connecting portion 242 can be detachably connected to the upper end of the container 300, so that the filter module 200 is detachably arranged between the water production device 100 and the container 300.

[0045] The inner side of the filter housing 240 is provided with a plurality of filter elements composed of different filter materials. In this embodiment, the filter module 200 can include a filter element composed of a first filter material 210, a second filter material 220, and a third filter material. The first filter material 210, the second filter material 220, and the third filter material 230 can be selected from one or more of the following types of filter materials: micropore filter, filter fiber, activated carbon, zeolite, medical stone, ion exchange resin, etc. It can remove impurities, odors, and harmful chemicals in the condensed water produced by the water making device 100, and make the water quality of the condensed water directly drinkable.

[0046] It is particularly noted that in this embodiment, since the filter module 200 is a detachable structure, the filter module 200 can be designed as a consumable of the device 1 for extracting water by condensing from the air of the present invention.

[0047] The container 300 is connected below the filter module 200 to contain the condensed water filtered by the filter module 200. The container 300 has a water storage space 310 for containing condensed water, and has an opening at the upper end and can be detachably connected to the lower end of the filter module 200.

[0048] The container 300 can be made of a transparent material, or at least a portion of the container 300 can be made transparent, so that the user can visually see the amount of condensed water stored in the container 300 and the water production status of the water production device 100. In this embodiment, the container 300 is made of an opaque material, and a long transparent window 320 is provided on one side of the container 300, so that the user can see the height of the condensed water inside the container 300 through the transparent window 320.

[0049] The water level sensor 555 is housed inside the container 300 . The water level sensor 555 is coupled to the microcontroller 510 , so that the microcontroller 510 can detect the water level of condensed water inside the container 300 through the water level sensor 555 , and stop making water when the container is full of water.

In addition, the condensation module 140 of the present invention has a flat cold end heat conduction plate 141, and a plurality of columnar conductive members 142 disposed on the surface of the cold end heat conduction plate 141, and a plurality of fins 143 disposed on the conductive member 142, which can increase the contact area between the condensation module 140 and the air, thereby effectively improving the efficiency and speed of condensation water making.
