Air purifier and air purifying system
An air purifying system may include at least three air cleaners or purifiers capable of independently operating and a docking station to support the at least three air purifiers. Since the air purifiers may be separated or stacked together on the docking station, the air purifying system may be operated in various states desired by a user.
1. An air purifying system comprising:
a first purifier;
a second air purifier positioned above the first air purifier;
a docking station provided with a backbone extending in a vertical direction;
a third air purifier supported by an upper surface of the second air purifier; and
at least one support extending laterally from the backbone, the at least one support including a bottom support extending laterally from a bottom of the backbone,
wherein the backbone is inclined at an acute angle relative to the bottom support,
wherein the first air purifier is positioned on the bottom support and the second air purifier is coupled to the backbone through a case of the second air purifier, and the first air purifier is detachable from the bottom support such that the first and second air purifiers operate independent from each other, and
wherein an air cleaning capacity of the second air has a larger air ea capacity than air cleaning capacities of the first and third air purifiers.
2. The air purifying system of claim 1 , wherein a bottom surface of at least one of the second or third air purifiers includes a flow guide to guide clean air discharged from a top of the first or second air purifiers, respectively, toward a side.
3. The air purifying system of claim 1 , wherein at least one of the first, second, or third air purifiers has a circular horizontal cross-section having an area that decreases from a bottom to a top.
4. The air purifying system of claim 3 , wherein the first, second, and third air purifiers have circular horizontal cross-sections.
5. The air purifying system of claim 3 , wherein a cross-sectional area of the third air purifier is smaller than cross-sectional areas of the first and second air purifiers.
6. The air purifying system of claim 1 , wherein the bottom support includes a seating groove extending from the backbone toward a front to guide a lateral slide of the first air purifier.
7. The air purifying system of claim 1 , wherein the backbone and the second air purifier are permanently attached to each other.
8. The air purifying system of claim 1 , wherein each of the first and second air purifiers includes:
a case having a fan and a filter therein;
a base provided below the case; and
an air guide protruding downward from a center of the base, an outer side of the air guide having a concave curvature.
9. The air purifying system of claim 8 , wherein the base is circular.
10. The air purifying system of claim 1 , wherein the air cleaning capacity of the third air purifier is smaller than the air cleaning capacities of first and second air purifiers.
11. The air purifying system of claim 1 , wherein the third air purifier is configured to be lifted from the upper surface of the second air purifier.
