TECHNICAL FIELD

The disclosure relates to the technical field of atmospheric water generation, more particularly to an atmospheric water generation system.

BACKGROUND

The atmospheric water generator is designed based on the principle that the refrigerant from the compressor can be compressed, condensed, and vaporized for cooling. In the evaporator pipe, the liquid refrigerant changes phase and vaporizes to absorb heat energy. Consequently, the vapor in the air can be condensed into water, which can be collected as a water source for the atmospheric water generator.

As the atmospheric water generator is internally arranged with devices such as a fan device and a condenser, it usually makes a loud noise during operation. Chinese utility model CN210887419U in relevant technology discloses an atmospheric water generator with low work noise. By means of acoustic panels provided on both top and bottom portions of the body of the water generator, it absorbs noise produced during operation of the body of the water generator. However, such solution for noise reduction fails to efficiently utilize internal energy and has high consumption. It is desired to improve its practicability.

SUMMARY

The disclosure aims to solve at least one of the above problems to some extent. To this end, one of the goals of the disclosure is to provide an atmospheric water generation system having low noise and utilizing energy efficiently with low consumption and improved practicability.

In order to achieve the above goal, the disclosure provides an atmospheric water generation system, comprising an atmospheric water generation device and a control device;

Herein, the control device is configured to control the operation of the atmospheric water generation system;

Herein, the atmospheric water generation device comprises a water evaporator, a condenser, a compressor, a fan device, and a noise reduction device, wherein the condenser is connected with the water evaporator, and the compressor is connected with the water evaporator and the condenser, so as to cyclically cool down and supply a refrigerant, the noise reduction device is disposed between the fan device and the compressor, and the fan device is disposed between the condenser and the compressor, such that outside air can pass through the water evaporator to produce water and cool air, the cool air can cool down the condenser and then flow to the noise reduction device to reduce noise, and then residual cool air can flow to the compressor and a heating component of the control device, for cooling and heat dissipation.

In the atmospheric water generation system according to the embodiment of the disclosure, outside air flows to the water evaporator under the action of the fan device, such that both water and cool air can be produced. The cool air can cool down the condenser, then can be treated by means of the noise reduction device for noise reduction. Then, residual cool air can flow to the compressor and heating components (for example the heat sink of the control plate) of the control device, for cooling. In this way, by using the noise reduction device to reduce noise produced in the atmospheric water generation system, and utilizing cool air to cool down the heating parts such as the condenser, the compressor, and the heat sink in the atmospheric water generation system, the system can reduce noise and meanwhile utilize residual cool air for cooling, thereby raising energy efficiency and improving practical performance of water generation.

Furthermore, several circumferentially-spaced guiding channels may be provided on the inner sidewall of each of the air passages. With such arrangement, the noise reduction device would not impede the transfer of the residual cool air, and optimized noise reduction effect can be achieved without affecting the air flow.

DETAILED DESCRIPTION OF ILLUSTRATED EMBODIMENTS

Embodiments of the disclosure are described below in detail. Examples of the embodiments are illustrated in the drawings, and same or identical reference numerals in this text indicate same or identical elements or elements with same or identical functions. It should be noted that, the embodiments explained below in conjunction with the accompanying drawings are merely illustrative examples and exemplary, and are not intended to limit the invention.

In order to more fully understand the technical solution, illustrative embodiments of the disclosure are explained in detail in conjunction with the drawings. Though the invention is described with reference to the drawings and exemplary embodiments, it should be understood that the invention can be implemented in a variety of forms, and the embodiments illustrated above are not intended to limit the invention. Instead, the embodiments are illustrated to facilitate understanding of the disclosure, and to make the disclosure clear for those skilled in the art.

The atmospheric water generation system of the disclosure is described in detail in conjunction with FIGS. 1-23.

First referring to FIGS. 1-4, an atmospheric water generation system is provided in an embodiment of the disclosure, which comprises an atmospheric water generation device 10 and a control device.

In particular, the control device is configured to control the operation of the atmospheric water generation system. The atmospheric water generation device 10 comprises a water evaporator 101, a condenser 102, a compressor 103, a fan device 104, and a noise reduction device 105. Herein, the condenser 102 is connected with the water evaporator 101, and the compressor 103 is connected with the water evaporator 101 and the condenser 102 so as to cyclically cool down and supply the refrigerant. The noise reduction device 105 is disposed between the fan device 104 and the compressor 103, and the fan device 104 is disposed between the condenser 102 and the compressor 103. In such a case, outside air can pass through the water evaporator 101 to produce water and cool air, the cool air can cool down the condenser 102 and flow to the noise reduction device 105 to reduce noise, and then the remained cool air can flow to the compressor 103 and heating components of the control device, for cooling and heat dissipation.

In another word, the water evaporator 101 can produce water and meanwhile produce cool air as well. The cool air treated by means of the noise reduction device 105 for noise reduction can cool down other heating parts inside the atmospheric water generation device 10. Thus, both noise problem and energy utilization problem can be solved by the atmospheric water generation system.

In conclusion, in the atmospheric water generation system, outside air flows to the water evaporator 101 under the action of the fan device 104, such that both water and cool air can be produced. The cool air cools down the condenser 102 and flows to the noise reduction device 105 to reduce noise, and then residual cool air can flow to the compressor 103 and heating components (for example the heat sink of the control plate) of the control device, for cooling. In this way, due to the air flow design and the noise reduction device 105, the noise produced in the atmospheric water generation system can be reduced. In the meantime, cool air can be utilized to cool down the heating parts such as the compressor 103, the condenser 102, and the heat sink in the atmospheric water generation system. Hence, the atmospheric water generation system reduces noise and meanwhile utilizes residual cool air for cooling, thereby raising energy efficiency and improving practical performance of water generation.

A basic solution of the disclosure is provided in the above embodiment, which can solve the problem raised in the background and achieve a goal of the disclosure. In order to achieve improved performance and advantages, the basic solution described above can be further defined in various aspects as below.

<Atmospheric Water Generation Device>

With respect to the atmospheric water generation device 10, referring to FIGS. 4-7, the noise reduction device 105 is connected with the air outlet of the fan device 104, such that all the air flowing from the fan device 104 can be introduced to the noise reduction device 105, to ensure noise reduction effect. Herein, the fan device 104 may be an axial flow fan.

More particularly, the noise reduction device 105 may comprise a plurality of pieces of sound absorbing cotton. The plurality of pieces of sound absorbing cotton may have a three-dimensional network structure, which is provided with a plurality of air passages 1051 extending through its top and bottom portions and has a cross section in a shape of nine-by-nine Sudoku grid. Thus, the noise reduction device 105, which is made of sound absorbing cotton designed in three-dimensional network structure with a cross section in a shape of nine-by-nine Sudoku grid, can provide a plurality of air passages 1051, thereby achieving optimized noise reduction effect without affecting the air flow.

Furthermore, in order to improve noise reduction effect, several circumferentially-spaced guiding channels may be provided on the inner sidewall of each of the air passages 1051. With such arrangement, the noise reduction device 105 would not impede the transfer of the residual cool air, and optimized noise reduction effect can be achieved without affecting the air flow.

Furthermore, in order to ensure cooling and heat dissipation effect of cool air on the heating components, the noise reduction device 105 may be provided with several types of V-shape grooves at a position close to it bottom. With such arrangement, the air transferred from the air passages 1051 can quickly flow out due to reduced wind resistance, thereby ensuring heat dissipation effect of the residual cool air.

Furthermore, the atmospheric water generation device 10 may comprise an air filter 106 arranged outside the water evaporator 101, and the fan device 104 may be configured to enable the air filtered by means of the air filter 106 to enter the water evaporator 101 for production of water and cool air. Herein, the air filter 106 may utilize current aerodynamic principles in combination with multiple filtration technology, to effectively filter out harmful gas in the air.

In the atmospheric water generation device 10, the compressor 103 and the condenser 102 work as follows. The refrigerant in the water evaporator 101 or the straight cooling tube 302 absorbs heat energy and turns into gas. Then, the gas is compressed into high-temperature, high-pressure gas by means of the compressor 103, and then is transferred to the condenser 102 and is cooled into refrigerant.

The refrigerant cooled by means of the condenser 102 may be transported to the water evaporator 101 through a pipeline, and an expansion valve may be provided in the pipeline. With such arrangement, the refrigerant can realize continuous cooling function in the water evaporator 101.

As mentioned above, the residual cool air flowed out of the noise reduction device 105 can dissipate heat from the heat sink 601. The control plate 603 of the control device is the main heating part, and the heat transferred by the heat sink 601 needs to be dissipated timely. As the control plate 603 and the heat sink 601 are disposed between the noise reduction device 105 and the compressor 103, the air flowed out of the noise reduction device 105 can dissipate heat from the heat sink 601. Such dissipation by using residual cool air can raise energy efficiency.

In order to ensure that the whole atmospheric water generation system is electrically controllable and operable, the control device may further comprise a control panel 602 for displaying control information and data parameters and allowing for input of setting information and control information. The control plate 603 (which may use an existing programmable logic controller) is configured to control the operation of the whole atmospheric water generation system.

<Water Collection Device>

Further referring to FIGS. 8-10, the atmospheric water generation system further comprises a water collection device 20, which comprises a water collecting tray 201, a water filter 202, and a water tank 203.

In particular, the water tank 203 is provided at its top surface with a water tank water inlet 2031, and is provided at a position close to its bottom portion with a water tank water outlet 2032 and a water tank drain outlet 2033. Herein, the water tank water outlet 2032 is spaced from the water tank drain outlet 2033. It is located above the water tank drain outlet 2033 and is higher than the bottom surface of the water tank 203. The water filter 202 is detachably mounted on the water tank water inlet 2031. The water collecting tray 201 is disposed between the water evaporator 101 and the water tank 203, to collect water produced by the water evaporator 101. The water collecting tray 201 is provided at its bottom with a water collecting tray water outlet 2011, to allow the collected water to flow through the water filter 202 and enter the water tank 203.

In such a case, the water collecting tray 201 serves to collect water produced by the water evaporator 101. The water flows from the water collecting tray water outlet 2011 to the water filter 202. After filtration, the water flows into the water tank 203. In such process, as the water collecting tray 201 and the water tank 203 are separately arranged and the water filter 202 is detachably mounted at the water tank water inlet 2031 provided on the top surface of the water tank 203, it is convenient to replace the water filter 202 to maintain water quality without disassembling the water tank 203. As the water tank water outlet 2032 is located above the water tank drain outlet 2033 and higher than the bottom surface of the water tank 203, a few centimeters of water may be retained at the bottom of the water tank 203, to get water deposits on the bottom surface of the water tank 203. In such a case, by utilizing external water for cleaning in cooperation with a circulating pump, a water pump and a drain outlet, the water tank 203 can drain water out to facilitate cleaning, so as to further maintain water quality without disassembling the water tank 203.

Furthermore, a gap is left between the water collecting tray 201 and the water tank 203, and the water collecting tray water outlet 2011 is aligned with the water tank water inlet 2031 in a vertical direction. With such arrangement, the water collecting tray 201 and the water tank 203 are disposed at appropriate positions.

Herein, the water tank 203 may have an elongated shape. The water tank 203 is provided with a fixing plate to facilitate mounting on the inner side wall of the accommodation cavity of the atmospheric water generation system. The water collecting tray 201 is disposed below the water evaporator 101 by using a mounting plate. In such a case, as the water collecting tray 201 and the water tank 203 are separately arranged, it achieves convenient cleaning and replacement, and the atmospheric water generation system has an impact internal structure.

In an implementation of detachable and replaceable water filter 202, the water filter 202 may have a bowl shape, and the top opening of the water filter 202 may be provided with a flanging for abutting against the edge of the water tank water inlet 2031. With such arrangement, in combination with the separate structure of the water tank 203 and the water collecting tray 201, it can be easily picked up and put down, and it is convenient to replace the water filter 202 to maintain water quality.

Furthermore, the water tank 203 is provided at its top with a cover plate for matching with various sizes of water filters 202.

With respect to the structure of the water collecting tray 201, the water collecting tray 201 is provided with a division plate 2012 dividing it into a first tray portion 2013 and a second tray portion 2014. Herein, the first tray portion 2013 has a funnel shape, and the water collecting tray water outlet 2011 is provided at the bottom of the first tray portion 2013. The division plate 2012 is provided with a through hole allowing for communication between the second tray portion 2014 and the first tray portion 2013. A groove is provided inside the second tray portion 2014. The groove extends to communicate with the through hole. Herein, the water collected in the second tray portion 2014 can be introduced into the first tray portion 2013 due to the groove and the through hole, and then flow through the water collecting tray water outlet 2011 into the water tank 203.

More particularly, the first tray portion 2013 may be located below the water evaporator 101, and the second tray portion 2014 may be located below the condenser 102. With such arrangement, it ensures that all water produced by the water evaporator 101 can be collected.

<Water Cooling Device>

Further referring to FIGS. 11-15, the atmospheric water generation system further comprises a water cooling device 30, which comprises a storage tank 301, a cold water pump, a straight cooling tube 302, a cold water circulating valve, and a cold water output valve. Herein, the straight cooling tube 302 utilizes a structure of tubular shape with multi-segment, comprising an inner tube (i.e., a cold evaporation tube) and an outer tube (i.e., a water container), to realize quick cooling function of water.

In particular, the inner tube of the straight cooling tube 302 is in communication with the condenser 102 and the compressor 103, so as to cyclically cool down and supply the refrigerant. The outer tube of the straight cooling tube 102 is in communication with the storage tank 301, the cold water circulating valve and the cold water output valve, and the cold water circulating valve allows the cold water to cyclically flow into the cold water pump.

In another word, the refrigerant used in the inner tube (i.e., the cold evaporation tube) of the straight cooling tube 302 of the water cooling device 30 can be compressed by the abovementioned compressor 103 and then transferred to the condenser 102 for cooling, and then cyclically transferred to the inner tube of the straight cooling tube 302. In such a case, the water evaporator 101 and the straight cooling tube 302 can share one set of compressor 103 and condenser 102. In addition, the water cooling device 30 functions to perform cooling during operation, and intermittently operate in the standby state. With such arrangement, one set of compressor 103 and condenser 102 can be shared to achieve condensation for producing water and cooling function by cold water, thereby reducing the number of parts of the whole atmospheric water generation system. Consequently, the whole system has compact structure with greatly reduced volume, reduced cost and consumption, and improved practicability.

More particularly, during operation of the water cooling device 30, the straight cooling tube 302 works when cold water output is needed. Under the action of the cold water pump, the water of the storage tank 301 flows to the straight cooling tube 302, and the straight cooling tube 302 quickly cools the water to a desired temperature (for example, 3-4° C.).

In addition, by means of the cold water pump, the straight cooling tube 302, and the cold water circulating valve, a circulation of cold water can be achieved. During the standby state or when cold water output is not needed, the straight cooling tube 302 can intermittently work, to ensure that the water in the straight cooling tube 302 is kept at a temperature of 3-4° C. In this way, consumption can be reduced and energy-saving effect can be achieved.

The refrigerant cooled by the condenser 102 may be transferred to the straight cooling tube 302 through a pipeline, and an expansion valve may be provided in the pipeline. With such arrangement, the refrigerant can realize continuous cooling function in the straight cooling tube 302.

In another word, the output pipeline of the condenser 102 is provided with a water-producing expansion valve and an instant cold expansion valve, wherein the water-producing expansion valve is connected with the condenser 102 and the water evaporator 101, and the instant cold expansion valve is connected with the straight cooling tube 302 and the condenser 102. In such a case, the refrigerant used by the water evaporator 101 and the straight cooling tube 302 can be compressed by means of the compressor 103 and then transferred to the condenser 102 for cooling, and then cyclically transferred to the water-producing expansion valve and the instant cold expansion valve. Depending on the requirements of water production volume and temperature, the water-producing expansion valve and the instant cold expansion valve can be respectively automatically adjusted. Then, it can be transferred to the water evaporator 101 and an evaporative cooler inside of the straight cooling tube 302. With such arrangement, the production volume and temperature of water can be conveniently automatically controlled.

In addition, in the water cooling device 30, the storage tank 301 may be withdrawably arranged in the accommodation cavity of the atmospheric water generation system. The water inlet and the water outlet of the storage tank 301 are provided with a first quick plug connector to facilitate removal for cleaning and quick mounting of storage tank 301.

In particular, the water cooling device 30 may further comprise a support 303 and a second withdrawable tray 304. Herein, the support 303 is fixedly arranged in the accommodation cavity of the atmospheric water generation system and defines a first groove 3031 opening at an end. Herein, the second withdrawable tray 304 is slidably connected with the first groove 3031 and defines a second groove 3041, and the storage tank 301 is disposed in the second groove 3041.
