Multiple-Water-Pans Humidifier

Abstract

Disclosed is a humidifier having multiple water pans stacked together with one water pan at the top of the stack and one water pan at the bottom of the stack and the remainder water pans in the middle of the stack; within each water pan, there are evaporate pads comprised of multiple layers and positioned in sequences like wave after wave. Water fills the water pan at the top the stack and continues to fill the water pans in the middle of the stack one by one and then the water pan at the bottom of the stack; in doing so, water moistens the evaporator pads within each water pan, while warm air moves through the evaporator pads, warm air absorbs moisture to create humidified air.

What is claimed is: 
     
         1 . A humidifier comprising:
 Water pans configured to hold a volume of liquid in each water pan,   Evaporate pads placed in each water pan,   Wherein the evaporator pads are structured to absorb water from the water pans and evaporate moisture when warm air flows through the evaporator pads.   
     
     
         2 . The humidifier according to  claim 1 , wherein the evaporate pads placed in each water pan are comprised of multiple layers and are arranged in sequences like wave after wave. 
     
     
         3 . The humidifier according to  claim 1 , wherein the water pans are positioned in a stack. 
     
     
         4 . The humidifier according to  claim 3 , wherein the water pans are stacked together and each water pan is placed in a level position; wherein an overflow draining hole is placed inside each water pan; wherein the height of the overflow draining hole is lower than the height of the water pan; wherein water flows from water tubing pipes and fill the first water pan at the top of the stack; wherein when the level of water in the first water pan exceeds the height of the overflow draining hole of the first water pan, water continuous to flow via the overflow draining hole of the first water pan to the water pan immediately below the first water pan; wherein when the level of water in the second water pan exceeds the height of the overflow draining hole of the second water pan, water continues to flow via the overflow draining hole of the second water pan to a water pan immediately below the second water pan; wherein in a similar fashion, water fills and flows through the water pans below the second water pan until it reaches the last water pan at the bottom of the stack; wherein when the level of water in the last water pan exceeds the height of the overflow draining hole of the last water pan, water drains out via the overflow draining hole of the last water pan. 
     
     
         5 . The humidifier according to  claim 3 , wherein the water pans are stacked together, the last water pan at the bottom of the stack is placed in a level position and all the other water pans are placed in slant positions; wherein a water chute is attached to the higher end of the first water pan at the top of the stack; wherein an overflow draining hole is placed inside the last water pan at the bottom of the stack and the height of the overflow draining hole is lower than the height of the last water pan at the bottom of the stack; wherein water flows from water tubing pipes and fills the water chute; wherein when the water chute is filled, water flows along the slant surface of the first water pan; wherein when water reaches the lower end of the first water pan, water drops through the opening at the lower end of the top water pan and reaches the higher end of the water pan immediately below the first water pan; wherein water continues to flow along the slant surface of the second water pan; wherein when water reaches the lower end of the second water pan, water drops through the opening at the lower end of the second water pan and reaches the higher end of the water pan immediately below the second water pan; wherein in a similar fashion, water continues to flow along the slant surfaces of the water pans under the second water pan until it reaches the lower end of the water pan which is positioned immediately above the last water pan at the bottom of the stack; wherein water drops through the opening at the lower end of the water pan which is placed immediately above the last water pan and continues to fill the last water pan. When the level of water in the last water pan exceeds the height of the overflow draining hole of the last water pan, water drains out via the overflow draining hole of the last water pan.
