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.

[0010] FIG. 2 is another perspective view of the humidifier.

[0011] FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 8 and FIG. 13 demonstrate that multiple evaporator pads are placed within each water pans and the evaporator pads are multiple-layered and formed in sequences like wave after wave.

[0012] FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7, FIG. 8 and FIG. 9 show the first method of how the multiple water pans are stacked.

[0013] FIG. 10, FIG. 11, FIG. 12 and FIG. 13 illustrate the second way of how the multiple water pans are stacked.

DETAILED DESCRIPTION OF THE INVENTION

[0014] FIG. 1 demonstrates a humidifier 1 is connected with a supply duct 2, and a return duct 3 through a duct 5. Warm air flows from a furnace 4 through the supply duct 2, and reaches the humidifier 1, wherein the direction of air flow 6 is from the supply duct 2 to the humidifier 1. Inside the humidifier 1, warm air absorbs moisture to become humidified air and flows through the duct 5 to the return duct 3, wherein the direction of air flow 6 is from the humidifier 1 to the return duct 3.

[0015] FIG. 2 is a back perspective view of the humidifier 1. FIG. 2 demonstrates a mounting cover 7, several mounting holes 8 which connect the humidifier 1 with the supply duct 2 in FIG. 1, an opening 9 which connects the humidifier 1 with the duct 5 in FIG. 1, water tubing pipes 10 and a valve 11.

[0016] FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 8 and FIG. 11 are different perspective views of the inside of the humidifier 1. FIG. 3 is a back perspective view of the humidifier 1 without the mounting cover 7 in FIG. 2. FIG. 4 is a front perspective view of the humidifier 1. FIG. 5 is a bottom perspective view of the humidifier 1 with the bottom of humidifier 1 cut open. FIG. 6 is another bottom perspective view of the humidifier 1. FIG. 8 is another back perspective view of the humidifier 1. FIG. 11 is a top perspective view of the humidifier 1. As FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 8 and FIG. 13 demonstrate, multiple water pans 12 are placed inside the humidifier 1; wherein the water pans 12 are positioned in stacks; wherein multiple evaporator pads 13 are positioned inside each water pan 12; wherein the evaporator pads 13 are structured in multiple layers and placed in each water pan 12 in the sequence of wave after wave.

[0017] FIG. 3, FIG. 4, FIG. 5, FIG. 6, FIG. 7 and FIG. 8 demonstrate the first way wherein water pans 12 are stacked together. Under the first method, the water pans 12 are placed in level positions and stacked together, wherein one water pan 12 is at the top of the stack, another water pan 12 is in the middle of the stack and another water pan 12 is at the bottom of the stack. Inside each water pan 12, there is an overflow draining hole 14. FIG. 5 and FIG. 6 show the draining hole 14 of the water pan 12 at the bottom of the stack. FIG. 7 illustrates the overflow draining hole 14 of the water pan 12 at the top of the stack. As FIG. 9 demonstrates, the height of the overflow draining hole 15 is lower than the height of the water pan 16.

[0018] Under the first method, water flows from water tubing pipes and fill the water pan 12 at the top of the stack. When the level of water in the water pan 12 at the top of the stack exceeds the height of the overflow draining hole 15, water continuous to flow via the overflow draining hole 14 inside the water pan 12 at the top of the stack to the water pan 12 in the middle of the stack. In a similar fashion, water continues to fill the water pan 12 in the middle of the stack and the water pan 12 at the bottom of the stack. When the level of water in the water pan 12 at the bottom of stack exceeds the height of the overflow draining hole 15, water drains out via the overflow draining hole 14 inside of the water pan 12 at the bottom of the stack.

[0019] FIG. 10, FIG. 11, FIG. 12 and FIG. 13 show the second method wherein water pans 12 are stacked together. According to the second way, the multiple water pans are stacked together, wherein the last water pan at the bottom of the stack is placed in a level position and all the other water pans atop the last water pan are placed in slant positions. As FIG. 10, FIG. 11 and FIG. 13 illustrate, the water pan 12 at the top of the stack and the water pan 12 in the middle of the stack are both positioned in slant positions and the water pan 12 at the bottom of the stack is placed in a level position.

[0020] Under the second method, a water chute 17 is attached to the higher end of the water pan 12 at the top of the stack. Water flows from water tubing pipes and fills the water chute 17. When the water chute 17 is filled, water flows along the slant surface of the water pan 12 at the top of the stack. As FIG. 10, FIG. 11 and FIG. 12 illustrates, when water reaches the lower end of the water pan 12 at the top of the stack, water drops through the opening 18 at the lower end of the water pan at the top of the stack and reaches the higher end of the water pan 12 in the middle of the stack. Water continues to flow along the slant surface of the water pan 12 in the middle of the stack. When water reaches the lower end of the water pan 12 in the middle of the stack, water drops through the opening 18 at the lower end of the water pan 12 in the middle of the stack, and reaches the higher end of the water pan 12 at the bottom of the stack, and continues to fill the water pan 12 at the bottom of the stack. Similar to the first method, when the level of water in the water pan 12 at the bottom of stack exceeds the height of the overflow draining hole 15, water drains out via the overflow draining hole 14 inside the water pan 12 at the bottom of the stack.
