Abstract

Disclosed is a powerless humidification module for an air cleaner which is capable of preventing leakage of water into the air cleaner. A powerless humidification module for an air cleaner which is detachably mounted on an upper portion of a body of the air cleaner and is capable of preventing leakage of water includes a base cover having a first opening opened toward the air cleaner and a second opening opened toward a side surface of the first opening, a cistern part located in the interior of the base cover and located such that a space defined between an inner partition wall and an outer partition wall having predetermined heights such that water supplied to one side thereof is stored surrounds a periphery of the first opening whereby water supplied to one side thereof is stored, and a humidification filter located in the second opening.

First claim

The invention claimed is:

1. A powerless humidification module for an air cleaner which is detachably mounted on an upper portion of a body of the air cleaner and is capable of preventing leakage of water, humidification module comprising:
a base cover having a first opening opened toward the air cleaner and a second opening opened toward a side surface of the first opening;
a cistern part located in an interior of the base cover and comprising an inner partition wall and an outer partition wall having predetermined heights, wherein a space, in which water supplied to the space is stored and which surrounds a periphery of the first opening, is formed between the inner partition wall and the outer partition;
a humidification filter located in the second opening and located in the space of the cistern part; and
a protector located in the interior of the base cover to communicate the first opening and the second opening and located to cover an upper portion of the first opening,
wherein the protector comprises:
an upper prevention wall located to cover the upper portion of the first opening; and
a guide wall extending from an outer periphery of the upper prevention wall to the space of the cistern part;
wherein the humidification module further comprises:
a water tank located above the upper prevention wall, wherein the water tank communicates with an injection cap located in the space of the cistern part, and water leaked while moving from the water tank to the injection cap flows into the guide wall of the protector.

2. The humidification module of claim 1 , further comprising:
a drain hole formed on one side of the base cover,
wherein when the water supplied to one side space of the cistern part overflows a predetermined height of an overflow recess formed in the outer partition wall, the water is discharged through the drain hole, overflowing the outer partition wall through the overflow recess.

3. The humidification module of claim 1 , further comprising:
a partition wall which has a height such that the space, in which the water of the cistern part is stored, is divided into one side space and an opposite side space,
wherein when the water supplied to one side space of the cistern part overflows a predetermined height of an overflow recess formed in the partition wall, the water is introduced into the opposite side space of the cistern part, overflowing the partition wall through the overflow recess.

4. The humidification module of claim 3 , further comprising:
a drain hole formed on one side of the base cover,
wherein when the water introduced to the opposite side space of the cistern part overflows a predetermined height of an overflow recess formed in the outer partition wall, the water is discharged through the drain hole overflowing the outer partition wall through the overflow recess.

5. The humidification module of claim 1 , further comprising:
a sensor configured to detect the level of the water stored in the space of the cistern part.

6. The humidification module of claim 2 , further comprising:
a sensor configured to detect the level of the water stored in the space of the cistern part.

7. The humidification module of claim 3 , further comprising:
a sensor configured to detect the level of the water stored in the space of the cistern part.

8. The humidification module of claim 4 , further comprising:
a sensor configured to detect the level of the water stored in the space of the cistern part.
