     FIELD OF THE INVENTION 
       [0002]    The present invention relates to the field of drinking water treatment systems, in particular, to an atmospheric water generator. 
       BACKGROUND OF THE INVENTION 
       [0003]    Generally, drinking water is required to be highly purified so that it will not adversely affect those who drink the water for a long period of time. In most developed countries, tap water has reached the standard for purified water. However, there are still many poorer regions in the world with relatively high prevalence rate and mortality rate due to the pollution of the water source, for example, pollutions caused by infectious germs, chemicals, the animal waste, heavy metals and the like. 
         [0004]    When the water source at the upper reaches of the river has been polluted by various pollution sources such as dumped waste, industrial emissions, contaminants released to the river as a result of soil erosion, and so on, the polluted water contains various chemicals, infectious viruses and bacteria which may cause various deadly diseases or severe diseases. Long-term drinking of polluted water can cause adverse affects on the human body. Therefore, as a general requirement, the water for drinking should be treated before being supplied for human consumption. 
         [0005]    All pollutants contained in the water can be effectively removed by existing water treatment technology. However, the purified water filtered by the water filtration system is generally stored in a water storage tank from which water is extracted for drinking. The purified water can become polluted by airborne pollutants or by other environmental factors while being stored.

         [0068]    In the atmospheric water generator  100  shown in  FIG. 1 , both of a middle door and a lower door are open. 
         [0069]    The atmospheric water generator  100  according to the present invention includes a main body bracket  114 , a water making system, a water purifying system and a water distributing device  126 . 
         [0070]    Two lateral sides and the back view of the main body bracket  114  are provided with panels, and air grilles are provided on the panels for intaking and exhausting air. In the present embodiment, three air grilles are provided, that is, the first air intake grille  116  and a second air intake grille  132  located at the two lateral sides of the main body bracket, and an air exhaust grille  134  located at the back view of the main body bracket. 
         [0071]    The water making system is provided in the main body bracket  114  and includes a condenser/evaporator unit  118 , a suction fan  140  and a water collecting tank  120 . The water collecting tank  120  is provided on the main body bracket  114  and is located under the condenser/evaporator unit  118 . The suction fan  140  is provided between the condenser/evaporator unit and the air grilles. When the air is sucked into the atmospheric water generator  100  through the air grilles by the suction fan  140 , the moisture in the air is condensed to drops of water when the air flowing through the condenser/evaporator unit  118  due to the low surface temperature of the evaporator, and the drops of water fall into the water collecting tank  120  from an outer wall of the evaporator. 
         [0072]    The water purifying system is provided in the main body bracket  114  and includes a water pump  122  (shown in  FIG. 2 ) and a filtration device  192 . One end of the water pump  122  is connected to the water collecting tank  120  via a pipeline, and the other end thereof is connected to the filtration device  192  via a pipeline, such that the water made and then collected in the water collecting tank  120  may be pumped into the filtration device  192  to be filtered and purified, thereby obtaining purified water. 
         [0073]    The water distributing device  126  is provided on the main body bracket  114  and is connected to a water outlet of the filtration device  192  via a pipeline, such that the obtained purified water may be outputted for drinking through the water distributing device  126 . 
         [0074]    In summary, in the atmospheric water generator  100  according to the present invention, the suction fan  140  is started to suck the ambient air into the atmospheric water generator  100 , and when the air flowing through the condenser/evaporator unit  118 , the moisture in the air is condensed to drops of water on the surface of the evaporator due to the condensing effect of the evaporator, and the drops of water flow into the water collecting tank  120  along the outer wall of the evaporator. The water in the water collecting tank  120  is conveyed into the filtration device  192  by the water pump  122  to be purified into purified water, and the purified water is conveyed into the water distributing device  126  and is then outputted for drinking from the water distributing device  126 . The present invention makes improvements to the prior art where two water tanks are needed, and the purified water has to be stored in a water storage tank and then is conveyed from the water storage tank to the water dispensing outlet for drinking. In contrast, according to the present invention, only one water tank (i.e., the water collecting tank  120 ) is needed, and the filtered water, without being stored, is conveyed directly to the water distributing device  126  for drinking directly, which completely solves the problems of the pollution and the bacteria-breeding of the purified water while being stored. 
         [0075]    Further, in order to improve the above technical solution, according to the present invention, two suction fans are respectively arranged between the condenser/evaporator unit  118  and the first air intake grille  116 , and between the condenser/evaporator unit  118  and the second air intake grille  132 . According to the present invention, by providing two suction fans, more air can be obtained, thus more water can be made. Since the suction fans are provided between the condenser/evaporator unit and the air intake grilles, the ambient air can be sucked onto the condenser/evaporator unit through the air intake grilles quickly for making raw water (raw water refers to water condensed by the evaporator).

         [0098]    The filtration device  192  includes a filter bracket  202  and a plurality of filters connected in series and provided on the filter bracket  202 . The filter bracket  202  is provided on the main body bracket  114 , and the plurality of filters connected in series are mounted on the filter bracket  202 . In the present embodiment, there are four filters, that is, the first filter  124 , the second filter  196 , the third filter  198  and the fourth filter  200  connected in series. The more the number of the filters are connected in series, the more complete the purification process is. 
         [0099]    The filter may be made from a single material or multiple materials, for example, plastic, resin, mineral, activated carbon, a film made from a plastic, and the like. Different filter materials may be selected to achieve different functions. The filter may be selected according to the impurities contained in the atmosphere. 
         [0100]    The filter seat  204  is configured to support a replaceable filter  206  and is provided on a filter bracket  202 . An inner wall of the filter seat  204  is provided with a protrusion, and the filter is provided with a locking recess  214  corresponding to the protrusion. When assembling the filter, rotate the filter  206  to engage the locking recess           with the protrusion, thereby locking the filter  206  tightly on the filter seat  204 . In the present invention, two protrusions spaced at an angle of 180 degree are preferably provided, that is, the first protrusion  210  and the second protrusion  212 , and accordingly, there are two locking recesses. 
         [0101]    The water flows into the filter  206  through a water inlet  216  and is discharged through a water outlet  218 . Each of the other filters is also connected to the corresponding filter seat  204  in the same way. The plurality of filter seats are connected in series by connecting the water outlet of one seat to the water inlet of the next. Water enters from the water inlet of the first filter and is discharged out of the water outlet of the last filter after being filtered by the plurality of filters. 
         [0102]    In order to provide hot water for drinking, the present invention further includes a purified water heating system provided within the main body bracket. The purified water heating system includes a heating device provided on the main body bracket and a heating pot provided on the heating device. The heating pot is connected to the water outlet of the filtration device via a pipeline or the water dispensing outlet of the water distributing device, such that the purified water may be fed into the heating pot and be heated by the heating device. The heating device may be an electromagnetic heating device or a resistive heating device. 
         [0103]    Preferably, the heating pot is located under the water dispensing outlet of the water distributing device such that the purified water can flow into the heating pot under gravity. 
         [0104]    In a case that the room temperature purified water is fed into the heating pot via the water distributing device, it requires that the water distributing device is provided with two water dispensing outlets, that is, a room temperature water dispensing outlet and a dispensing outlet for the water to be heated. The heating pot is connected to the dispensing outlet for the water to be heated via a pipeline. Thereby it can supply people not only with room temperature water but also with hot water. 
         [0105]    Reference may be made to  FIG. 13  which is a structural schematics of a hot water system according to an embodiment of the present invention.

         [0107]    The heating pot  220  includes a seat  222  and a top portion  224 . The seat  222  may be made from metal, such as copper, steel, iron, aluminum or other metals or alloys, and may be heated by the heating device  226 . Generally, the heating pot  220  is placed on the heating device  226 , and the water in the heating pot  220  will be heated. A valve  228  is provided on the top portion  224  of the heating pot  220 , and when the valve  228  is open, the purified water can enter the heating pot  220 . The valve  228  may also be connected to the second water pipe  178  directly or indirectly (the valve  228  is connected to the water outlet of the filtration device or the water dispensing outlet of the water distributing device via a pipeline) to receive the purified water discharged from the filters. 
         [0108]    Preferably, the purified water heating system according to the present invention further includes a first detecting device. When the first detecting device detects that the heating pot  220  is placed on the heating device  226 , the valve  228  is controlled to open, otherwise the valve  228  is closed, thus when the heating pot is removed, the valve is closed, which may prevent the purified water from spilling out. 
         [0109]    Preferably, the purified water heating system according to the present invention further includes a second detecting device and a display device. When the first detecting device detects that the heating pot  220  is placed on the heating device  226 , the heating device  226  is controlled to start; and when the second detecting device detects that the water in the heating pot  20  reaches a preset temperature, the heating device  226  is controlled to stop, and the display device displays an alarm signal. The display device includes two light-emitting diodes, when the water in the heating pot is in a heated state, a first light-emitting diode is on; and when the water in the heating pot reaches the preset temperature, a second light-emitting diode is on. The preset temperature can be preset by the user and may be set according to different requirements to the water temperature. Generally, the preset temperature is set as 100 centigrade, which is the temperature of the water in a boiled state. 
         [0110]    Preferably, the present invention further includes a third detecting device. When the third detecting device detects that the impurity content of the water in the water collecting tank exceeds a preset value, the atmospheric water generator is stopped. The preset value is a concentration value of the water preset by the user. A large amount of sand may be deposited in the water collecting tank being used for a long time. At this time, the concentration of the water in the water collecting tank becomes large, and when the concentration reaches the preset value, the atmospheric water generator is stopped. 
         [0111]    In addition, the present invention further includes a rapid heating device, being connected to the water outlet of the filtration device and the water dispensing outlet of the water distributing device. The rapid heating device may be a ceramic type heating device or a quartz tube type heating device. The purified water can be heated in real time when flowing through the preheated rapid heating device. 
         [0112]    In order to facilitate the moving of the atmospheric water generator, the present invention further includes wheels provided at the bottom portion of the main body bracket. 
         [0113]    Reference may be made to  FIG. 14  which is a sectional view taken along line A-A of  FIG. 3 . 
         [0114]    As shown in the figure, the ambient air outside the atmospheric water generator enters the atmospheric water generator through the second air intake grille  132  and the first air intake grille  116  respectively located at two sides of the main body bracket  114 , and then is exhausted from the exhaust grille  134  at the back portion. After entering the bracket  114 , the air may be guided to the air filter screen  138  to remove the dust in the air, and flows through the condenser/evaporator unit  118  and the suction fan  140  in order, and then is exhausted from the exhaust grille  134  on the main body bracket  114 . Through the above process, the moisture in the air can be condensed to drops of water by the evaporator and then is collected in the water collecting tank  120 . 
         [0115]    Preferably, according to the present invention, the suction fan is provided between the condenser/evaporator unit  118  and the exhaust grille  134  to exhaust the air in the atmospheric water generator. During the exhausting process, air will be supplied into the atmospheric water generator through the second air intake grille  132  and the first air intake grille  116 . Certainly, the suction fan may also be provided between the condenser/evaporator unit  118  and the second air intake grille  132 , and/or between the condenser/evaporator unit and the first air intake grille  116 . Under this situation, the suction fan has to suck the air into the atmospheric water generator, and accordingly, the air in the atmospheric water generator will be exhausted through the exhaust grille  134 . 
         [0116]    In summary, the first embodiment of the present invention provides an atmospheric water generator including a main body bracket, wherein two lateral sides and the back side of the main body bracket are provided with panels, and air grilles are provided on the panels for the air to flow in and out freely. Two parts are provided in the main body bracket: one is the water making system, and the other is the water purifying system. Both parts are mounted on the main body bracket, and components of the two parts are linked with each other to perform the water making and water purifying functions. 
         [0117]    The water making system includes a condenser/evaporator unit, a suction fan and a water collecting tank. When the water making system is started, the surface temperature of the evaporator drops, the air driven by the suction fan flows through the surface of the evaporator and is condensed to drops of water to be collected in the water collecting tank under the condenser/evaporator unit. The water collecting tank is connected to the main body bracket, and can be completely separated from the main body bracket for cleaning. 
         [0118]    The water purifying system includes a water pump, a filtration device and a water distributing device. One end of the water pump is connected to the water collecting tank via a water pipe, and the other end thereof is connected to the filtration device via a water pipe. The water outlet of the filtration device is connected to the water dispensing outlet via a water pipe. When a water dispensing outlet switch is turned on, the water pump is started by an internally installed electronic circuit to transport the raw water to the filter, and then the purified water after being filtered is output via the water dispensing outlet for drinking directly. 
         [0119]    The second embodiment of the present invention provides an atmospheric water generator with heating function. The purified water heating system includes a heating pot, a heating device which may be an electromagnetic heating device or a resistive heating device, a detecting device, an electronic circuit control system, and a light-emitting diode. The heating pot is arranged under the water dispensing outlet and on top of the heating device. When the purified water enters the heating pot, the heating device is started to heat the purified water in the heating pot to the boiling point or the preset temperature, then under control of a temperature sensor and the electronic circuit, the heating device stops automatically. The operation process is displayed by the light-emitting diodes having different colors provided on the main body bracket. 
         [0120]    The third embodiment of the present invention provides an atmospheric water generator which can provides hot water in real time. When the atmospheric water generator is started, the surface temperature of the evaporator drops, the air driven by the suction fan flows through the surface of the evaporator and is condensed to drops of water to be collected in the water collecting tank under the condenser/evaporator unit. The water collecting tank is connected to the main body bracket, and can be completely separated from the main body bracket for cleaning. The water purifying system includes a water pump, filters and a water distributing device. One end of the water pump is connected to the water collecting tank via a water pipe, and the other end thereof is connected to the filter via a water pipe. The water outlet of the filter is connected to a rapid heating device via a water pipe, and the rapid heating device is connected to the water dispensing outlet via a water pipe. When the water dispensing outlet switch is turned on, the water pump is started by an internally installed electronic circuit to transport the water in the water collecting tank to the filtration device for purification, then the purified water after being filtered is transported to the rapid heating device, and then the water is being heated rapidly and is discharged via the water dispensing outlet. 
         [0121]    As shown in  FIG. 15 , the water collecting tank  120  is connected to the water pump  122  via the first pipeline, the water pump  122  is connected to the filtration device  192  via the second pipeline, and the filtration device  192  is connected to the water distributing device  126  via the third pipeline. Specifically, the present invention includes a recirculation pipeline  700  connecting the third pipeline and the water collecting tank  120 . 
         [0122]    During the normal operation process, when the water distributing device  126  is started, the water pump  122  is started simultaneously to pump the raw water in the water collecting tank  120  into the filtration device  192  for filtering via the second pipeline, and then the purified water being filtered flows into the water distributing device  126  via the third pipeline and then flows out of the water distributing device  126 . 
         [0123]    In a case that the atmospheric water generator according to the present invention is not in use for a long time, that is, the water distributing device  126  is kept idle, the water pump  122  may be started to pump the raw water in the water collecting tank  120  into the filtration device  192  for filtering via the second pipeline, and then the purified water being filtered flows into the recirculation pipeline  700  via the third pipeline, and then flows back to the water collecting tank  120 , thereby completing a recirculation loop. 
         [0124]    Overall, according to the present invention, a bypass, that is, the recirculation pipeline  700 , connects the water collecting tank  120  with the third pipeline before it enters into the water distributing device  126 , such that when the water pump  122  is started, the raw water is pumped from the water collecting tank  120  to the filtration device  192  via the pipelines, then is transported back to the water collecting tank  120  through the recirculation pipeline  700  without flowing through the water distributing device  126 , which may realize the cleaning of the internal pipelines and filtering out all the bacterium by the filtration device  192 . Therefore, without starting the water distributing device  126 , the recirculation of the water in the water collecting tank  120  and the cleaning of the pipelines of the atmospheric water generator can be realized. 
         [0125]    In order to ensure that the purified water will not flow back to the water collecting tank  120  through the recirculation pipeline  700  when the water distributing device  126  is started, an electromagnetic switching valve is provided on the recirculation pipeline  700 . When the water distributing device  126  is started, the electromagnetic switching valve is turned off; and only in the case that the water distributing device  126  is not in use and the water pump  122  is started, the electromagnetic switching valve is turned on. That is, only in the case that the water distributing device  126  is in use and the water pump  122  is started, the purified water may flow back to the water collecting tank  120  via the recirculation pipeline  700 , such that the purified water cannot flow back to the water collecting tank  120  via the recirculation pipeline  700  when the purified water is in use. 
         [0126]    For realizing a pipeline automatic cleaning function, the present invention further includes a controller for timing control of starting and stopping the water pump  122 . The controller may set a time interval between two recirculations and the duration of the water pump  122  in operation (that is, the duration for each recirculation), such that the water pump  122  may be started by the controller to perform the automatic recirculation after a preset time interval, so as to clean the pipelines of the atmospheric water generator. The time recording begins when the water pump  122  is started, and when reaching the preset recirculation time, the water pump  122  is stopped by the controller. When the water pump  122  is stopped, the time recorder begins to time again, and when reaching the preset time interval, the water pump  122  is started again, and the recirculation goes on. 
         [0127]    The present invention further includes a three-way connector  400 , one outlet thereof is connected to the water distributing device  126  via a pipeline, and the other two water outlets thereof are connected to the said third pipeline and the recirculation pipeline  700 , respectively. Due to the three-way connector  400 , the water distributing device  126 , the third pipeline and the recirculation pipeline  700  are connected with one another. 
         [0128]    The short pipeline (that is, the pipeline between the three-way connector and the water distributing device  126 ) between the bypass (the recirculation pipeline  700 ) and the water distributing device  126  is not flushed in the above recirculation system, thereby the bacterium may breed therein. In view of this, the present invention further includes a waste collector  300  provided under the water distributing device  126 . The water distributing device  126  may be started manually by the user such that the purified water is supplied from the system to the water distributing device  126  and is collected by the waste collector  300 , and then is piped back to the water collecting tank  120 , thereby realizing the manual flushing of this pipeline and the distributing device  126 . After flushing the he water distributing device  126  and the pipeline, recirculation, the purified water will contains no bacterium contamination and thus can be drunk safely. 
         [0129]    Furthermore, in order to improve the above technical solutions, the waste collector  300  provided by the present invention is connected to the water collecting tank  120  via the fourth pipeline  800 . The water collecting tank  120  is located at a very low position of the atmospheric water generator, in relation to the position of the water distributing device  126 . This means that the waste collector  300  is located higher than the water collecting tank  120 , thus the water collected into the waste collector  300  can flow back to the water collecting tank  120  under gravity via the fourth pipeline  800 . 
         [0130]    The embodiments of the present invention are described herein in a progressive manner. The description of each of the embodiments is mainly focused on difference thereof from the other embodiments, and references may be made among various embodiments with respect to the same or similar parts thereof. 
         [0131]    As will be apparent to those skilled in the art in the light of the foregoing disclosure, many alterations and modifications are possible in the practice of this invention without departing from the spirit or scope thereof. Accordingly, the scope of the invention is to be construed in accordance with the substance defined by the claims and is not limited to the embodiments illustrated herein.
