Detailed Description
To facilitate an understanding of the present application, the present application will now be described more fully with reference to the accompanying drawings. Preferred embodiments of the present application are illustrated in the accompanying drawings. This application may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.
Referring to fig. 1, a method for controlling a moisture collection device includes steps S100, S200, and S300.
And step S100, when the moisture collection device is started to operate, acquiring ambient air parameters.
Specifically, the moisture collection device is started to operate, that is, the controller in the moisture collection device receives a start signal and starts to perform an operation corresponding to moisture collection. The opening signal can be specifically sent by a user, namely when the user needs to collect moisture in the air by using the moisture collection device, the user directly sends the opening signal to the controller. When the controller receives the opening signal and starts to execute the moisture collection program, the controller firstly obtains the ambient air parameters, namely obtains the air-related parameters of the environment where the current moisture collection device is located.
It should be noted that the manner in which the controller obtains the ambient air parameters is not exclusive. In one embodiment, the moisture collection device may include a parameter collector for collecting the ambient air parameter, and after the controller receives the start signal, the parameter collector is accessed in real time to obtain the corresponding ambient air parameter, or the parameter collector actively sends the ambient air parameter to the controller in real time. In another embodiment, the ambient air parameter may also be actively input by the user, and in which manner different choices may be made in connection with the actual usage scenario.
And S200, analyzing according to the ambient air parameters and a preset dew point database to obtain the dew point temperature required for condensing the moisture in the air at present.
Specifically, the preset dew point database stores all possible ambient air parameters, and the condensation temperature required when the moisture in the air is condensed into water drops for collection is correspondingly stored. After the controller obtains the ambient air parameters of the current environment, the obtained ambient air parameters are directly matched and analyzed with a preset dew point database prestored in the controller, and accordingly the corresponding required dew point temperature is obtained.
Step S300, adjusting the surface temperature of a condensing device of the moisture collecting device to be lower than the dew point temperature, so that the moisture in the air is condensed into water drops on the surface of the condensing device.
Specifically, the moisture collecting device is provided with a condensing device as a place where moisture in air condenses, and by adjusting the surface temperature of the condensing device to be below the dew point temperature, when moisture in air contacts the surface of the condensing device, gaseous moisture condenses into liquid water drops due to temperature difference and adheres to the surface of the condensing device, so that the moisture in air is collected.
It should be noted that, in order to facilitate the use of the moisture collection device in an environment without a power source, such as in a drought field, in one embodiment, the condensing device may be a solar panel, and the condensing device is connected to a controller and other components, and may convert solar energy into electric energy to supply power to the controller, the parameter collector, and the like. The moisture collecting device obtained by the scheme of the embodiment can be used in extreme environments of water shortage and electricity shortage, and has stronger use convenience. Meanwhile, in order to better condense the moisture in the air, the surface of the solar panel can also be made of stainless steel and other materials. Further, in one embodiment, the solar panel is a photovoltaic solar panel, and the photovoltaic effect is used for directly converting solar energy into electric energy.
Furthermore, in one embodiment, the solar panel may be configured as a honeycomb structure, and particularly as shown in fig. 2, the solar panel with the simulated honeycomb structure can increase the contact area of the solar panel with air, so that more air (equivalent to more water in gaseous state) contacts the surface of the solar panel. Under the condition that the surface temperature of the solar panel is lower than the dew point temperature, more liquid water can be condensed on the surface of the solar panel, and the moisture collection efficiency of the moisture collection device is effectively improved. It can be understood that the thickness of the solar honeycomb panel is not exclusive, and different settings can be specifically carried out in combination with the use scene or the user requirements as long as sufficient contact with air is ensured.
Referring to fig. 3, in one embodiment, the step of adjusting the surface temperature of the condensing device of the moisture collecting device to be less than the dew point temperature includes steps S310 and S320.
Step S310, acquiring the surface temperature of a condensing device of the moisture collecting device, and comparing and analyzing the surface temperature with the dew point temperature; in step S320, when the surface temperature is greater than or equal to the dew point temperature, the surface temperature of the condensing device of the moisture collecting device is adjusted to be less than the dew point temperature.
Specifically, when the surface temperature of the condensation device of the moisture collection device is adjusted to be less than the dew point temperature, the real-time surface temperature of the condensation device in actual use should be adjusted in real time. Therefore, the parameter collector in this embodiment further includes a condensation surface temperature collector, which is disposed on the surface of the condensing device and is used for collecting the surface temperature of the condensing device in real time and sending the surface temperature to the controller. After the controller receives the real-time surface temperature, the surface temperature and the dew point temperature are subjected to ratio analysis, and different control operations are realized according to the comparison and analysis results. When the surface temperature of the condensing device is greater than or equal to the dew point temperature, the surface temperature of the condensing device is correspondingly reduced, so that the moisture in the air is condensed into water drops on the surface of the condensing device.
Referring to fig. 3, in an embodiment, after step S310, the method further includes step S330.
And step S330, when the surface temperature is lower than the dew point temperature, maintaining the surface temperature of the condensing device of the moisture collection device unchanged.
Specifically, when the controller performs a comparative analysis based on the matched dew point temperature and the received surface temperature, a situation may also occur in which the surface temperature of the condensing device is already lower than the dew point temperature, which means that moisture in the air can be condensed on the surface of the condensing device, and there is no need to further lower the surface temperature. Therefore, when the surface temperature of the condensing device is less than the dew point temperature, it is only necessary to maintain the current surface temperature of the condensing device.
It should be noted that the particular manner of adjusting the surface temperature of the condensing device is not exclusive and in one embodiment may be achieved by providing a refrigeration device in the moisture collection apparatus, the refrigeration device being connected to the controller. Correspondingly, step S320 includes: and when the surface temperature is greater than or equal to the dew point temperature, reducing the operating power of the refrigerating device of the moisture collection device, returning to the step of acquiring the surface temperature of the condensing device of the moisture collection device and comparing and analyzing the surface temperature with the dew point temperature until the surface temperature of the condensing device of the moisture collection device is less than the dew point temperature.
Specifically, the refrigeration device refers to a device capable of reducing the surface temperature of the condensation device through refrigeration, and the larger the operating power of the refrigeration device is, the stronger the refrigeration capacity of the corresponding refrigeration device is. When the controller detects that the surface temperature of the condensing device is greater than or equal to the dew point temperature, the controller sends an instruction of increasing the operation power to the refrigerating device of the moisture collecting device, and the refrigerating capacity of the refrigerating device is increased, so that the surface temperature of the condensing device is reduced.
It will be appreciated that after the controller has adjusted the cooling capacity of the cooling device, it is not the case that the surface temperature of the condensing device drops directly below the condensing temperature. Therefore, after the operating power of the refrigeration device is increased, the surface temperature of the condensation device of the moisture collection device needs to be further acquired and compared with the dew point temperature for analysis, and the current operating power is maintained until the surface temperature of the condensation device is reduced to be lower than the dew point temperature.
The type of the cooling device is not exclusive, and any cooling device may be used as long as the surface temperature of the condensing device can be changed. For example, in one embodiment, the refrigeration device is a semiconductor refrigerator. A semiconductor Cooler (Thermoelectric Cooler) is a device that uses the Thermoelectric effect of a semiconductor to produce cooling energy, and is also called a Thermoelectric Cooler. When two different metals are connected by a conductor and direct current is applied, the temperature at one junction is reduced and the temperature at the other junction is increased. The surface of the condensing device is refrigerated by using the semiconductor refrigerator, and the device has the advantages of no need of a refrigerant, small volume, light weight and the like, so that the use reliability of the moisture collecting device is ensured.
It should be noted that the type of ambient air parameter is not exclusive, as long as it can be used to distinguish between the desired dew point temperatures for different ambient air, and for example, in one embodiment, the ambient air parameters include ambient air temperature and ambient air humidity. Correspondingly, in this embodiment, the parameter collector includes an ambient temperature collector and an ambient humidity collector, and the ambient temperature collector and the ambient humidity collector are respectively connected to the controller for respectively collecting and sending the ambient air temperature and the ambient air humidity to the controller.
It can be understood that, for different types of ambient air parameters, the corresponding preset dew point database is not unique, and when the ambient air parameters are ambient air temperature and ambient air humidity, the corresponding preset dew point database represents the corresponding dew point temperature under the combination of the different ambient air temperatures and the different ambient air humidity. In a detailed embodiment, the specific correspondence is shown in fig. 4.
To facilitate understanding of various embodiments of the present application, the following description is made in conjunction with a specific application scenario. Referring to fig. 5, the first scene is: when the water supply is cut off at home, the condensate water device is opened, and the solar panel calls the solar energy to supply power for the controller, the refrigerating device and the like. The controller receives the ambient air temperature and humidity collected and sent by the parameter collector, for example, the temperature is 28 ℃ and the humidity is 50%. The controller reads a dew point temperature of 17.5 ℃ through a preset dew point database. The semiconductor refrigeration device is controlled to start to operate at a certain power, in the process, if the surface temperature of the solar panel received by the controller is greater than or equal to 17.5 ℃, the operation power of the semiconductor refrigeration device is controlled to be increased, the surface temperature of the solar panel is maintained below 17.5 ℃, moisture in the air begins to condense in large quantity, and condensed water can be collected for domestic water.
Scene two: need drink water or wash on the way in the travel, but can not find suitable water source this moment, can open condensate water collection device, collect the comdenstion water after condensate water collection device operation, but feel the rate of condensation this moment too slow, can manually adjust the power of condensate water collection device (also the operating power of semiconductor refrigerator), increase the semiconductor refrigeration effect, make the temperature of solar energy honeycomb panel be less than dew point temperature to accelerate the rate of condensation of moisture in the air, solve the problem that lacks the water source.
According to the control method of the moisture collection device, the ambient air parameters in the real-time environment can be obtained when the device is started to operate, and then the obtained ambient air parameters are compared with the preset dew point database for analysis, so that the dew point temperature required for condensing and collecting moisture in the air in the current environment is obtained. And finally, the surface temperature of the condensing device is controlled to be lower than the corresponding dew point temperature, so that when the air is in contact with the surface of the condensing device, the moisture in the air is condensed on the condensing device, and the moisture in the air is collected. By the scheme, water molecules in the air can be collected and condensed into water under the condition of water pollution or field (particularly in arid regions such as deserts) so as to provide fresh water resources for users, and the problems of water resource shortage and water pollution are effectively solved.
Referring to fig. 6, a control device of a moisture collection device includes an air parameter obtaining module 100, a dew point temperature analyzing module 200, and a moisture condensing module 300.
The air parameter acquiring module 100 is used for acquiring ambient air parameters when the moisture collecting device is started to operate; the dew point temperature analysis module 200 is used for analyzing according to the ambient air parameters and a preset dew point database to obtain the dew point temperature required for condensing moisture in the air at present; the moisture condensation module 300 is used for adjusting the surface temperature of the condensation device of the moisture collection device to be less than the dew point temperature, so that the moisture in the air is condensed into water drops on the surface of the condensation device.
In one embodiment, the moisture condensation module 300 is further configured to obtain a surface temperature of a condensation device of the moisture collection apparatus and compare the surface temperature with a dew point temperature for analysis; and when the surface temperature is greater than or equal to the dew point temperature, adjusting the surface temperature of the condensing device of the moisture collection device to be less than the dew point temperature.
In one embodiment, the moisture condensation module 300 is further configured to maintain a surface temperature of a condensation device of the moisture collection apparatus when the surface temperature is less than the dew point temperature.
In one embodiment, the moisture condensation module 300 is further configured to reduce the operation power of the refrigeration device of the moisture collection device when the surface temperature is greater than or equal to the dew point temperature, and return to the operation of obtaining the surface temperature of the condensation device of the moisture collection device and comparing the obtained surface temperature with the dew point temperature for analysis until the surface temperature of the condensation device of the moisture collection device is less than the dew point temperature.
For specific definition of the control device of the moisture collection device, reference may be made to the above definition of the control method of the moisture collection device, and details are not repeated here. The respective modules in the control device of the moisture collection device described above may be entirely or partially implemented by software, hardware, and a combination thereof. The modules can be embedded in a hardware form or independent from a processor in the computer device, and can also be stored in a memory in the computer device in a software form, so that the processor can call and execute operations corresponding to the modules.
The control device of the moisture collecting device can acquire the ambient air parameters in the real-time environment when the control device is started to operate, and then the acquired ambient air parameters are compared and analyzed with a preset dew point database to obtain the dew point temperature required for condensing and collecting moisture in the air in the current environment. And finally, the surface temperature of the condensing device is controlled to be lower than the corresponding dew point temperature, so that when the air is in contact with the surface of the condensing device, the moisture in the air is condensed on the condensing device, and the moisture in the air is collected. By the scheme, water molecules in the air can be collected and condensed into water under the condition of water pollution or field (particularly in arid regions such as deserts) so as to provide fresh water resources for users, and the problems of water resource shortage and water pollution are effectively solved.
Referring to fig. 7, a moisture collecting apparatus includes a controller 20, a parameter collector 10 and a condensing device 30, wherein the parameter collector 10 and the condensing device 30 are respectively connected to the controller 20, and the controller 20 is configured to condense moisture in air into water drops on a surface of the condensing device 30 according to the above-mentioned method.
Specifically, the moisture collection device is turned on to operate, which means that the controller 20 in the moisture collection device receives the on signal and starts to perform the operation corresponding to the moisture collection. The opening signal may be specifically sent by the user, that is, the user directly sends the opening signal to the controller 20 when the user needs to collect the moisture in the air by using the moisture collecting device. When the controller 20 receives the start signal to start the moisture collection procedure, it first obtains the ambient air parameters, that is, obtains the air-related parameters of the environment where the moisture collection device is currently located.
The moisture collecting device comprises a parameter collector 10 for collecting the ambient air parameters, and after the controller 20 receives the opening signal, the parameter collector 10 is accessed in real time to obtain the corresponding ambient air parameters, or the parameter collector 10 actively sends the ambient air parameters to the controller 20 in real time.
The preset dew point database stores all possible ambient air parameters, and the condensation temperature required when the moisture in the air is condensed into water drops for collection is correspondingly stored. After obtaining the ambient air parameters of the current environment, the controller 20 directly performs matching analysis on the obtained ambient air parameters and a preset dew point database prestored in the controller 20, so as to obtain the corresponding required dew point temperature.
The moisture collecting device is provided with the condensing device 30 as a place where moisture in the air is condensed, and by adjusting the surface temperature of the condensing device 30 to be below the dew point temperature, when the moisture in the air contacts the surface of the condensing device 30, the moisture is condensed into liquid water drops in a gaseous state due to temperature difference and is attached to the surface of the condensing device 30, so that the collecting operation of the moisture in the air is realized.
Referring to fig. 8, in one embodiment, the parameter collector 10 includes an ambient temperature collector 11 and an ambient humidity collector 12, and the ambient temperature collector 11 and the ambient humidity collector 12 are respectively connected to the controller 20.
It should be noted that the type of ambient air parameter is not exclusive, as long as it can be used to distinguish between the desired dew point temperatures for different ambient air, and for example, in one embodiment, the ambient air parameters include ambient air temperature and ambient air humidity. Correspondingly, in this embodiment, the parameter collector 10 includes an ambient temperature collector 11 and an ambient humidity collector 12, and the ambient temperature collector 11 and the ambient humidity collector 12 are respectively connected to the controller 20 for respectively collecting and sending the ambient air temperature and the ambient air humidity to the controller 20.
With continued reference to fig. 8, in one embodiment, the parameter collector 10 further includes a condensation surface temperature collector 13, and the condensation surface temperature collector 13 is connected to the controller 20.
Specifically, when the surface temperature of the condensation device 30 of the moisture collection device is adjusted to be less than the dew point temperature, the real-time surface temperature of the condensation device 30 at the time of actual use should be adjusted in real time. Therefore, the parameter collector 10 in this embodiment further includes a condensation surface temperature collector 13, and the condensation surface temperature collector 13 is disposed on the surface of the condensation device 30 for collecting the surface temperature of the condensation device 30 in real time and sending the collected surface temperature to the controller 20. After receiving the real-time surface temperature, the controller 20 will perform a comparison analysis of the surface temperature and the dew point temperature, and implement different control operations according to the comparison analysis result. When the surface temperature of the condensing device 30 is greater than or equal to the dew point temperature, the surface temperature of the condensing device 30 is adjusted to be low accordingly, so that the moisture in the air is condensed into water drops on the surface of the condensing device 30.
Referring to fig. 9, in an embodiment, the moisture collecting apparatus further includes a refrigerating device 40, the refrigerating device 40 is disposed on the condensing device 30 (not shown), and the refrigerating device 40 is connected to the controller 20.
It should be noted that the specific manner of adjusting the surface temperature of the condensing device 30 is not exclusive and in one embodiment may be achieved by providing a refrigeration device 40 in the moisture collection apparatus, the refrigeration device 40 being connected to the controller 20. Correspondingly, step S320 includes: and when the surface temperature is greater than or equal to the dew point temperature, reducing the operating power of the refrigeration device 40 of the moisture collection device, returning to the step of acquiring the surface temperature of the condensation device 30 of the moisture collection device, and comparing and analyzing the surface temperature with the dew point temperature until the surface temperature of the condensation device 30 of the moisture collection device is less than the dew point temperature.
Specifically, the refrigerating device 40 refers to a device capable of reducing the surface temperature of the condensing device 30 by refrigeration, and the greater the operating power of the refrigerating device 40, the greater the refrigerating capacity of the corresponding refrigerating device 40. When the controller 20 detects that the surface temperature of the condensing device 30 is greater than or equal to the dew point temperature, the controller 20 sends an instruction to increase the operation power to the cooling device 40 of the moisture collecting apparatus, and the cooling capacity of the cooling device 40 is increased, so that the surface temperature of the condensing device 30 is decreased.
It is understood that after the controller 20 adjusts the cooling capacity of the cooling device 40, it is not the case that the surface temperature of the condensing device 30 drops directly below the condensing temperature. Therefore, after the operating power of the refrigeration device 40 is increased, the surface temperature of the condensation device 30 of the moisture collection device needs to be further acquired and compared with the dew point temperature for analysis, and the current operating power is maintained until the surface temperature of the condensation device 30 drops below the dew point temperature.
The type of the cooling device 40 is not exclusive as long as it is a cooling device capable of varying the surface temperature of the condensing device 30. For example, in one embodiment, the refrigeration device 40 is a semiconductor refrigerator. A semiconductor Cooler (Thermoelectric Cooler) is a device that uses the Thermoelectric effect of a semiconductor to produce cooling energy, and is also called a Thermoelectric Cooler. When two different metals are connected by a conductor and direct current is applied, the temperature at one junction is reduced and the temperature at the other junction is increased. The surface of the condensing device 30 is refrigerated by using the semiconductor refrigerator, and the device has the advantages of no need of a refrigerant, small volume, light weight and the like, thereby ensuring the use reliability of the moisture collecting device.
In one embodiment, the condensing device 30 is a solar panel.
Specifically, in order to facilitate the moisture collecting device to be used in an environment without a power supply, such as a drought environment, the condensing device 30 may be a solar panel, and the condensing device 30 is connected to the controller 20, and the like, and may convert solar energy into electric energy to supply power to the controller 20, the parameter collector 10, and the like. The moisture collecting device obtained by the scheme of the embodiment can be used in extreme environments of water shortage and electricity shortage, and has stronger use convenience. Meanwhile, in order to better condense the moisture in the air, the surface of the solar panel can also be made of stainless steel and other materials. Further, in one embodiment, the solar panel is a photovoltaic solar panel, and the photovoltaic effect is used for directly converting solar energy into electric energy.
Furthermore, in one embodiment, the solar panel may be configured as a honeycomb structure, and particularly as shown in fig. 2, the solar panel with the simulated honeycomb structure can increase the contact area of the solar panel with air, so that more air (equivalent to more water in gaseous state) contacts the surface of the solar panel. Under the condition that the surface temperature of the solar panel is lower than the dew point temperature, more liquid water can be condensed on the surface of the solar panel, and the moisture collection efficiency of the moisture collection device is effectively improved.
Referring to fig. 10, in one embodiment, the moisture collecting apparatus further includes a water storage device 50, and the water storage device 50 is connected to the condensing device 30. Specifically, in order to facilitate the collection and utilization of the water drops condensed on the surface of the condensing device 30, the moisture collection apparatus of the present embodiment further includes a water storage device 50, an inlet of the water storage device 50 may be connected to the bottom of the condensing device 30 through a conduit or the like, and after the water drops condensed on the surface of the condensing device 30 move toward the bottom of the condensing device 30 due to the gravity, the water drops finally flow into the water storage device 50 through the conduit to be collected.
The moisture collecting device can acquire the ambient air parameters in the real-time environment when the device is started to operate, and then the acquired ambient air parameters are compared and analyzed with a preset dew point database to obtain the dew point temperature required for condensing and collecting moisture in the air in the current environment. Finally, the surface temperature of the condensing device 30 is controlled to be lower than the corresponding dew point temperature, so that when the air is in contact with the surface of the condensing device 30, the moisture in the air is condensed on the condensing device 30, and the moisture in the air is collected. By the scheme, water molecules in the air can be collected and condensed into water under the condition of water pollution or field (particularly in arid regions such as deserts) so as to provide fresh water resources for users, and the problems of water resource shortage and water pollution are effectively solved.
A household appliance comprises the moisture collecting device.
Specifically, as shown in the above embodiments, the moisture collecting device is applied to the household electrical appliance with a small water consumption in the embodiment, and the collected water is used for domestic electrical appliance water and can also be used in an extreme water-deficient environment, so that the water resource is saved, and the water-deficient problem is effectively solved.
Specifically, the moisture collection device is turned on to operate, which means that the controller 20 in the moisture collection device receives the on signal and starts to perform the operation corresponding to the moisture collection. The opening signal may be specifically sent by the user, that is, the user directly sends the opening signal to the controller 20 when the user needs to collect the moisture in the air by using the moisture collecting device. When the controller 20 receives the start signal to start the moisture collection procedure, it first obtains the ambient air parameters, that is, obtains the air-related parameters of the environment where the moisture collection device is currently located.
The moisture collecting device comprises a parameter collector 10 for collecting the ambient air parameters, and after the controller 20 receives the opening signal, the parameter collector 10 is accessed in real time to obtain the corresponding ambient air parameters, or the parameter collector 10 actively sends the ambient air parameters to the controller 20 in real time.
The preset dew point database stores all possible ambient air parameters, and the condensation temperature required when the moisture in the air is condensed into water drops for collection is correspondingly stored. After obtaining the ambient air parameters of the current environment, the controller 20 directly performs matching analysis on the obtained ambient air parameters and a preset dew point database prestored in the controller 20, so as to obtain the corresponding required dew point temperature.
The moisture collecting device is provided with the condensing device 30 as a place where moisture in the air is condensed, and by adjusting the surface temperature of the condensing device 30 to be below the dew point temperature, when the moisture in the air contacts the surface of the condensing device 30, the moisture is condensed into liquid water drops in a gaseous state due to temperature difference and is attached to the surface of the condensing device 30, so that the collecting operation of the moisture in the air is realized.
The household appliance equipment is provided with the moisture collecting device, the ambient air parameters under the real-time environment can be acquired when the moisture collecting device is started, then the acquired ambient air parameters are compared and analyzed with the preset dew point database, and the required dew point temperature for condensing and collecting moisture in the air under the current environment is obtained. Finally, the surface temperature of the condensing device 30 is controlled to be lower than the corresponding dew point temperature, so that when the air is in contact with the surface of the condensing device 30, the moisture in the air is condensed on the condensing device 30, and the moisture in the air is collected. By the scheme, water molecules in the air can be collected and condensed into water under the condition of water pollution or field (particularly in arid regions such as deserts) so as to provide fresh water resources for users, and the problems of water resource shortage and water pollution are effectively solved.
