CROSS-REFERENCE TO RELATED APPLICATION 
       [0001]    This application claims priority to U.S. Provisional Application No. 62/327,571 filed Apr. 26, 2016, and entitled “Water Maker Device,” which is hereby incorporated by reference herein in its entirety, including figures, tables, equations or drawings. 
     
    
     TECHNICAL FIELD 
       [0002]    The system and methods disclosed herein relate to a device to make water from air within a closed system. 
       BACKGROUND 
       [0003]    Water resources, especially clean water, face the prospect of becoming scarcer due to growing population and industrialization. The majority of uses for water require fresh water. Fresh water, however, only encompasses 3% of the world&#39;s water supply. A majority of this small percentage is frozen or below ground and not readily available for human consumption. To provide water due to increasing demands, water making machines have become available. 
         [0004]    Conventional machines may make water from air. These machines first condense air in a cooler and then gather the water drops. The water machines that use these processes depend upon the humidity within the air to generate the water drops. The efficiency of these machines is low in low humidity environments, and may not be able to produce any water at all. Further, the time to make the water may be lengthy. Thus, for low humidity conditions, the conventional water making machine may not be a solution to meet the increasing demand for fresh water. 
       BRIEF SUMMARY 
       [0005]    A water making device according to the disclosed embodiments provides a water making capacity that is greater and faster than known machines. The disclosed water making device also works efficiently in low humidity environments. Moreover, the disclosed water making device draws less energy during use because it uses a smaller compressor. 
         [0006]    The disclosed process quickly makes water from air by creating a frost portion within the water making device. The disclosed process then heats and melts the frost portion within the water making device. The water may be purified and converted into high quality drinking or fresh water. 
         [0007]    A water making device is disclosed. The water making device includes a structure to form an interior. The interior holds air.

       [0011]    Other objects, features, and characteristics of the present invention, as well as methods of operation and functions of the related elements of the structure and the combination of parts, will become more apparent upon consideration of the following detailed description with reference to the accompanying drawings. 
       DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0012]    A detailed illustrative embodiment of the present invention is disclosed herein. However, techniques, methods, processes, systems and operating structures in accordance with the present invention may be embodied in a wide variety of forms and modes, some of which may be quite different from those in the disclosed embodiment. Consequently, the specific structural and functional details disclosed herein are merely representative, yet in that regard, they are deemed to afford the best embodiment for purposes of disclosure. The following presents a detailed description of the preferred embodiment of with reference to the figures. 
         [0013]    Referring initially to  FIG. 1 , shown is water making device  100  according to the disclosed embodiments. Water making device  100  creates a frost portion  102  at a certain thickness in the inside layer of the device by allowing controlled air therein. Water making device  100  cools down the interior to below the freezing point of water or 0 degrees Celsius. When a specified thickness of the frost portion is achieved, a sensor  104  stops the cooling process. A heating process begins. The heating process continues until frost portion  102  is melted to a specified thickness. Water making device  100  operates at intervals by switching between the heating and cooling processes. Generated water  106  is collected in a water tank  108 , which is then sent to a system connected to the water making device. Water making device  100  continues working until water tank  108  is filled. Water making device  100  may stop automatically. 
         [0014]    The embodiments of water making device  100  are disclosed in greater detail below. Water making device  100  includes components to facilitate the heating and cooling processes to form water  106 . These components include resistance  110 , which wraps around an inside surface of structure  120  of water making device  100 . An air controller  112  includes a fan  113  to create an air flow into the interior of water making device  100 . Air controller  112  also may receive hot air  116  from resistance  110 . This process is explained in greater detail below. 
         [0015]    Water making device  100  also includes a programmer  114  for timing and control. Programmer  114  may employ several functions, including instructing other components when to operate and when to start/finish processes. Programmer  114  may include logic and components to perform these functions, such as a processor, a memory to store instructions executed on the processor, a data base to connect the processor to the memory, and the like. Programmer  114  receives inputs from these components to determine what actions to take within water making device  100 . Specifically, programmer  114  receives inputs from sensor  104  and air controller  112  to control operations. 
         [0016]    Structure  120  is shown as having a cylindrical shape, but may be other shapes as well. Structure  120  defines the interior of water making device  100  where ambient air is received from air controller  112 . A power input  122  provides power to the components within water making device  100 . Preferably, power input  122  receives AC power between about 110 to about 220 volts at a frequency of 45-65 hertz. Programmer  114  may convert the input voltage to values needed by the individual components, such as 24 volts to air controller  112 . 
         [0017]    A preferred process is disclosed. Initially, the inside of water making device  100  is cooled down to around 20 degrees Celsius using pipes  109 . The air circulation of ambient air into water making device  100  is provided by air controller  112 . As noted above, air controller  112  may operate on a direct current (DC) voltage of 24 volts. Smart automatic programmer  114  instructs air controller  112  when to circulate the air. 
         [0018]    When the temperature inside structure  120  of water making device  100  is below 20 degrees Celsius, air controller  112  lets the ambient air go inside structure  120 . This air creates frost crystals inside the surface of structure  120 . The amount of frost forms frost portion  102  on the inside of water making device  100 . Frost portion  102  grows in thickness as the process is repeated to bring in new air. The thickness of frost portion  102  is measurable by sensor  104 . 
         [0019]    Frost is created for frost portion  102  until it reaches a preset thickness value. Sensor  104  sends a signal to programmer  114  that the preset value has been reached. This period may initially last approximately 45 minutes for the first cooling cycle, and may last about 20 minutes in subsequent cycles. 
         [0020]    Upon detection of the preset thickness, programmer  114  may initiate the heating process. The heating process uses resistance  110 , which wraps around the interior of water making device  100 . Hot air  116  from resistance  110  circulates inside water making device  100  via fan  113  in air controller  112 . Frost portion  102  melts upon coming into contact with hot air  116 . This melted frost becomes water  106 . Water  106  collects at the bottom of water making device  100  and flows into water tank  108 . Water  106  may be collected in a conical tray  107 . 
         [0021]    The heating process may continue until the temperature in the interior is 90 degrees Celsius or sensor  104  detects that frost portion  102  is at a certain thinness. In other words, the specified thickness of frost portion  102  has been reduced a certain amount. Preferably, the specified thickness should not be zero, but a small amount to encourage the formation of ice crystals. Preferably, the heating process should last about 10 minutes. 
         [0022]    Water  106  passes through drain valve  124 . Drain valve  124  may be controlled by programmer  114 . Thus, water  106  is not continuously flowing from conical tray  107 . A small volume water making device  100  may have a capacity of two liters. At this capacity, water making device  100  may be instructed to make water of between 10-100 liters per day. The generated water may be used in agriculture, industry, irrigations or cleaning. The water may go through a filtering process in order to become drinkable water. 
         [0023]    Thus, for example, programmer  114  may instruct refrigerant unit  190  to circulate coolant through pipes  109  to cool down the inside of water making device  100 . The air within device  100  lowers in temperature, as detected by thermostat  118 . When the temperature of the air reaches 20 degrees Celsius, then programmer  114  instructs air controller  112  to allow ambient air inside the interior. Frost portion  102  is created. 
         [0024]    When frost portion  102  achieves a thickness, for example, of 2 centimeters, sensor  104  alerts programmer  114 . Programmer  114  sends an instruction to refrigerant unit  190  to finish the cooling process. Hot air  116  then flows through resistance  110  to melt frost portion  102 . The heating process continues until frost portion  102  is reduced to, for example, 0.5 centimeters. Then, the cooling process is repeated. 
         [0025]    The above values are for illustrative purposes only. Any value may be used for the thickness or thinness of frost portion  102 . The values may depend on the size of water making device  100  and other factors, such as how much water is to be generated during each cycle. 
         [0026]    While the present invention has been described with reference to the preferred embodiment, which has been set forth in considerable detail for the purposes of making a complete disclosure of the invention, the preferred embodiment is merely exemplary and is not intended to be limiting or represent an exhaustive enumeration of all aspects of the invention. It will be apparent to those of skill in the art that numerous changes may be made in such details without departing from the spirit and the principles of the invention. It should be appreciated that the present invention is capable of being embodied in other forms without departing from its essential characteristics.
