20240019142
This application claims priority under 35 U.S.C. § 119 to Korean Application No. 10-2022-0087010 filed in Korea on Jul. 14, 2022, whose entire disclosure(s) is/are hereby incorporated by reference.
An air cleaner, and more particularly, an air cleaner capable of utilizing a top space of the air cleaner is disclosed herein.
An air cleaner is a device that generates an air flow and filters the flowing air to improve the quality of indoor air in a certain space. An air cleaner may have a configuration in which an inlet is provided on one side, an outlet is provided on another side, and a filter is provided therein. The air cleaner may have the outlet at the top such that filtered air may be discharged upward and flow in into an indoor space. When the outlet is provided at the top, a fan for controlling a wind direction may be separately provided at the top to blow the filtered air to a long distance.
An air cleaner discussed in Korean Laid-Open Patent Publication No. 2021-0140930 includes a cylindrical body; an outlet that is open at the top of the body; an annular outlet grille provided with the outlet and defining a top or upper surface of the body; and an operating unit disposed on a flat surface surrounded by the annular outlet grille. Furthermore, the discussed air cleaner has an outlet that is provided on the top surface of the body, which is disadvantageous to utilize a top surface of the air cleaner. In addition, the operating unit is disposed at a central portion of the annular outlet, which makes it even more difficult to use the narrow flat surface of an upper end of the air cleaner.
A typical air cleaner may require a considerable volume in order to achieve air cleaning performance in a certain space, but since the large-volume air cleaner may occupy a significant portion of the space, the space utilization may be reduced accordingly. In order to increase the utilization of the space occupied by an air cleaner, another member having a storage space may be provided at the air cleaner. However, air discharged upward collides with the member and may not reach a long distance, which directly may lead to a decrease in performance of the air cleaner. Thus, there is a need for an air cleaner that can utilize the top space, while minimizing a reduction of the air quality performance.
The above reference is incorporated by reference herein where appropriate for appropriate teachings of additional or alternative details, features and/or technical background.

Hereinafter, aspects of an air cleaner 3 will be described with reference to
The first body 1 may include a circumferential wall formed along its circumference. The first body 1 may include a top or upper surface defining an upper end of the circumferential wall. For example, the first body 1 may have a cylindrical shape elongated in a height direction, and may include a cylindrical circumferential wall.
It should be appreciated that the first body 1 may be formed in a cylindrical shape, a cuboid shape, a pyramid shape, or a cube shape. However, the shape of the first body 1 is not limited thereto and may have various shapes. The first body 1 may decrease in width toward the top to have a relatively narrower top. For example, the first body 1 may have a cylindrical shape whose width decreases upward.
The inlet 112 may be formed in the circumferential wall of the first body 1. In another example, the inlet 112 may be formed on a bottom surface of the first body 1. A portion of the circumferential wall of the first body 1 may be open to define the inlet 112. The inlet 112 may allow air from outside of the first body 1 to flow inside of the first body 1. For example, a portion of the circumferential wall of the first body 1 may be cut out such that the inside of the first body 1 communicates with the outside of the first body 1 via the inlet 112, allowing outside air to be supplied to the inside through the inlet 112.
The inlet 112 may be formed along a circumference of the circumferential wall of the first body 1. The inlet 112 may be formed on one side of the circumferential wall of the first body 1. A plurality of inlets 112 may be provided in the circumferential wall of the first body 1. For example, with respect to a center in a height direction of the first body 1, four inlets 112 may be open in all directions on the circumferential wall.
The inlet 112 may be disposed at a lower side or part of the first body 1. For example, the inlet 112 may be spaced downward from a center in a height direction of the first body 1, and may be formed by opening a portion of the circumferential wall. Accordingly, contaminated air with high density may be easily introduced into the air cleaner through the inlet disposed at the lower side of the first body 1.
The inlet 112 may be provided with a louver 111. The louver 111 may be disposed outside the inlet 112. The louver 111 may be formed along the circumference of the circumferential wall of the first body 1. The louver 111 may be elongated in a height direction of the first body 1. A plurality of louvers 111 may be disposed along the circumference of the circumferential wall. Air may flow through gaps between the plurality of louvers 111. For example, the louver 11 elongated in the height direction of the first body 1 may be provided in plurality disposed along the circumference of the circumferential wall of the first body 1, and outside air may be introduced into gaps formed between the plurality of louvers 111. Accordingly, larger dust or foreign particles carried in air introduced into the inlet 112 may be filtered out by the louver 111.
The inlet 1 may be formed on one side of the first body 1, and the outlet 17 may be formed on another side of the first body 1. The outlet 17 may be disposed to be spaced apart from the inlet 112. The inlet 112 may be open on one side, and the outlet 17 may be open on another side. For example, the inlet 112 may be open on the circumferential wall of the first body 1, and the outlet 17 may be open at the top of the first body 1.
The outlet 17 may be formed by opening the first body 1. The upper surface and the circumferential wall of the first body 1 may be open to define the outlet 17. The first body 1 may be open at the top to define a portion of the outlet 17. For example, the outlet 17 may be formed by the first body 1 being open at the top. As air is drawn into a lateral surface of the first body 1 and is then discharged upward, the discharged air may be prevented from being reintroduced into the inlet 112.
The outlet 17 may have the shape of a transverse section of the first body 1. The outlet 17 may be smaller than a cross-section of the transverse section of the first body 1. A portion of the upper surface of the first body 1 may be open to define the outlet 17. For example, the outlet 17 may be formed in an annular shape at the top of the first body 1 with a cylindrical shape.
The first body 1 may include a lower housing 11. The lower housing 11 may define a portion of the circumferential wall of the first body 1. The inlet 112 may be formed in a circumferential wall of the lower housing 11. The lower housing 11 may have a shape that is relatively narrow at the top and relatively wide at the bottom. The louver 111 may be disposed on the circumferential wall of the lower housing 11. The louver 111 may be disposed at the inlet 112 formed in the circumferential wall of the lower housing 11. For example, the lower housing 11 may include a circumferential wall that is provided with the inlet 112, and the louver 111 that extends in the height direction of the first body 1 and is disposed along the circumference of the circumferential wall.
The first body 1 may include an upper housing 16. The upper housing 16 may be a portion of the first body 1. An outlet grille 18 may be connected to the upper housing 16. For example, the upper housing 16 may define an upper portion of the first body 1, and the outlet grille 18 may be connected to an upper edge of the upper housing 16.
The air cleaner 3 may include a second body (also referred to as an air deflector or tabletop) 2 disposed over the first body 1. A top or upper surface of the second body 2 may be formed substantially flat. The second body 2 may have the shape of a table. For example, the second body 2 may have the shape of a table with a flat top surface. Accordingly, space utilization of the air cleaner 3 may be increased.
The second body 2 may cover the first body 1. The second body 2 may extend in a lateral direction. A width of the second body 2 may be greater than a width of the first body 1. An edge of the second body 2 may be located further outward from a center axis of the air cleaner 3 relative to the circumferential wall of the first body 1. For example, the second body 2 may be greater in width than the first body 1, and the second body 2 may have the shape of a circular or oval table with an upper edge located outward relative to the circumferential wall of the first body 1.
The second body 2 may include a top or upper surface. The upper surface of the second body 2 may be formed substantially flat. The second body 2 may include a plate (or top plate) 24 having a substantially flat surface. The plate 24 may cover the second body 2. For example, the plate 24 may be a disk that extends in the lateral direction to cover the second body 2.
The air cleaner 3 may include an indicator (or indicator light) 26. The indicator 26 may provide a user with information about the air cleaner 3. The indicator 26 may visually convey information about the air cleaner 3 to the user. For example, the indicator 26 may be a display that visually displays information regarding an operation state of the air cleaner 3.
The indicator 26 may be provided on one side of the air cleaner 3. The indicator 26 may be disposed at the second body 2. The indicator 26 may face upward. The indicator 26 may be disposed at the upper surface of the second body 2. The indicator 26 may be inserted into a slot 241 formed in the upper surface of the second body 2. For example, the indicator 26 may be elongated, and may be disposed at the slot 241 formed in the upper surface of the second body 2.
The air cleaner 3 may include a charging pad 271. The charging pad 271 may charge portable electronic devices. The charging pad 271 may wirelessly charge an electronic device without a connection terminal. For example, the charging pad 271 may be a wireless inductive charging module.
The charging pad 271 may be provided on one side of the air cleaner 3. The charging pad 271 may be disposed on one side of the second body 2. The charging pad 271 may be disposed at the upper surface of the second body 2. The charging pad 271 may define a section of the upper surface of the second body 2. The charging pad 271 may be inserted into a pad hole 242 formed in the second body 2. For example, the charging pad 271 may be inserted into the circular pad hole 242 formed in the upper surface of the second body 2 to thereby define a section of the upper surface of the second body 2.
The air cleaner 3 may include a base 32 to support the first body 1. The base 32 may support the weight of the air cleaner 3. The base 32 may support the weight of the first body 1 and the second body 2. The base 32 may be disposed at a bottom of the first body 1. The base 32 may define a lower end of the first body 1. A width of the base 32 may be greater than the width of the first body 1. An end of the base 32 may be located outward relative to the circumferential wall of the first body 1. For example, the first body 1 may have a shape that is narrow at the top and wide at the bottom, and the base 32 may be greater in width than the lower end of the first body 1.
The base 32 may extend laterally. The base 32 may include an inclined wall 323 inclined downward toward the outside. An edge of the inclined wall 323 may be located outward relative to the circumferential wall of the first body 1. Accordingly, stability of the air cleaner 3 may be improved.
Referring to
The outlet 17 may be disposed obliquely. The outlet 17 may be positioned along a tilted surface. The outlet 17 may be tilted toward the outside of the first body 1. The outlet 17 may be inclined to one side from a connection point between the second body 2 and the first body 1. For example, the outlet 17 with an annular shape may be inclined downward toward the outside of the first body 1 from the connection portion between the first body 1 and the second body 2. Accordingly, discharged air may flow along the lower surface of the second body 2, thereby preventing the discharged air from being reintroduced into the inlet 112.
The outlet 17 may be formed in an annular shape. The outlet 17 may have the shape of a ring with respect to an axis of a blower fan 12. In other examples, the outlet 17 may have a circular shape, or the outlet 17 may have a quadrangular shape. The shape of the outlet 17 is not limited thereto, and may be formed in various shapes. For example, the outlet grille 18 may be disposed at an end of a flow path through which air is discharged, and the outlet 17 may have the shape of a rectangle provided between a plurality of vanes 181 disposed at the outlet grille 18. Accordingly, a discharge air flow may be generated in all directions, allowing the efficiency of the air cleaner to be increased.
The outlet 17 may be formed at an outlet cover. The outlet cover may be the outlet grille 18. For example, the outlet grille 18 may include a plurality of vanes 181, and the outlet 17 may be formed between the plurality of vanes 181. In another example, the outlet cover may be a plate having one or more holes defining the outlet 17.
The second body 2 may extend in the lateral direction. The second body 2 may include a lower cover 22 that defines an outer appearance of a bottom of the table. The lower cover 22 may extend in the lateral direction. The lower cover 22 may include a bottom or lower surface that extends laterally.
The lower cover 22 may decrease in thickness toward an end thereof. The lower surface of the lower cover 22 may be a guide wall 221. The guide wall 221 may extend in the lateral direction. The guide wall 221 may extend from the upper end of the first body 1 (e.g., adjacent to opening 17). The guide wall 221 may extend toward the outside of the first body 1. An edge of the guide wall 221 may be located outward relative to the circumferential wall of the first body 1.
The guide wall 221 may face downward. The guide wall may face the first body 1. The guide wall 221 may be inclined. For example, the guide wall 221 may extend upward toward the outside of the first body 1. The lower cover 22 may extend from one end of the outlet 17. The lower cover 22 may extend from one end of the outlet grille 18.
One end of the outlet grille 18 may be connected to the lower cover 22. The lower cover 22 may be spaced upward from another end of the outlet grille 18. The outlet 17 and the guide wall 221 may form an acute angle.
The outlet grille 18 and the guide wall 221 may be connected to each other. An upper end of the outlet grille 18 may be connected to a lower end of the guide wall 221. The outlet grille 18 and the guide wall 221 may form an acute angle. The guide wall 221 may extend from one side of the outlet grille 18, and the outlet grille 18 and the guide wall 221 may form an acute angle on the one side. The angle formed by the guide wall 221 and the outlet grille 18 may increase from the one side toward the edge of the guide wall 221. For example, the outlet grille 18 disposed at the top of the first body 1 may be connected to the second body 2, and the outlet grille 18 and the guide wall 221 of the second body 2 may form an acute angle at a connection point. The vane 181 may form an acute angle with the guide wall 221.
Referring to
The plate 24 may include a top or upper surface. As shown in
The plate 24 may have the slot 241 into which the indicator 26 is inserted. The indicator 26 may be inserted from below into the slot 241. The indicator 26 may be exposed at the upper surface of the second body 2. The indicator 26 may define a section of the upper surface of the second body 2. For example, the plate 24 may have the corresponding slot 241 into which an indicator 26 extending to one side is inserted, and the indicator 26 may be inserted from a bottom of the plate 24 into the slot 241 and may be exposed to the outside from above plate 24.
The plate 24 may have the pad hole 242 into which the charging pad 271 is inserted. The charging pad 271 may be inserted from a bottom of the plate 24 into the pad hole 242. The charging pad 271 may be exposed at the upper surface of the second body 2. The charging pad 271 may define a section of the upper surface of the second body 2. For example, the charging pad 271 may have a circular shape, and the pad hole 242 may be formed in a circular shape corresponding to the charging pad 271, allowing the charging pad 271 to be inserted into the pad hole 242 so as to be exposed to the outside from above the plate 24.
The indicator 26 and the charging pad 271 may have different shapes. For example, the indicator 26 may have an elongated shape, and the charging pad 271 may have a circular shape. Due to the different shapes of the indicator and the charging pad, a coupling direction of the plate 24 may be easily identified by a user.
The indicator 26 and the charging pad 271 may be disposed at opposite positions. For example, the indicator 26 may be disposed adjacent to one end of the major axis L1, and the charging pad 271 may be disposed adjacent to an opposite end of the major axis L1. Accordingly, a coupling direction of the plate 24 may be guided through the indicator 26 and the charging pad 271.

The lamp housing 261 and the pad hole 242 may be opposite to each other in a radial direction of the plate 24 relative to a center axis (e.g., along major axis L1). The plate 24 may include a lateral cover (or lateral cover wall) 243. The lateral cover 243 may be bent from a top surface of the plate 24 to extend downward. The lateral cover 243 may cover sides of the upper plate 23 and the lower cover 22 in the lateral direction.
Referring to
The outlet cover may be disposed to be spaced apart from and below the second body 2. The outlet cover may be spaced apart from the lower cover 22 of the second body 2. The outlet cover may be spaced apart from the lower cover 22 by a predetermined vertical distance m. The lower cover 22 may be spaced upward from the outlet cover by the predetermined distance m. The separation distance m between the lower cover 22 and the outlet cover may vary and may increase toward the outside of the first body 1. The outlet cover may be the outlet grille 18. For example, the outlet grille 18 may be inclined downward toward the outside of the first body 1, the lower cover 22 may be inclined upward toward the outside of the first body 1, and the separation distance m between the outlet grille 18 and the lower cover 22 may increase in a direction away from a center axis and toward the outside of the first body 1.
The guide wall 221 may be formed obliquely with respect to a radial direction of the second body 2. The guide wall 221 may be tilted with respect to the radial direction of the second body 2. The guide wall 221 may be inclined upward toward the edge.
The lower cover 22 may be convex downward. The guide wall 221 may be a curved surface. For example, the guide wall 221 may be convex downward. A curvature of the guide wall 221 may increase toward the edge of the second body 2. Accordingly, a discharge air flow may be generated along the guide wall 221 up to an edge of the lower cover 22 by the Coanda effect.
An angle Θ3b between the guide wall 221 and an outward radial direction of the second body 2 may be greater than zero. The angle Θ3b between the guide wall 221 and the outward radial direction of the second body 2 may be variable. The angle 03b between the guide wall 221 and the radial direction of the second body 2 may increase toward the edge of the guide wall 221.
An angle Θ3a between the outlet grille 18 and a radial direction of the first body 1 may be greater than zero. The angle Θ3a between the outlet grille 18 and the radial direction of the first body 1 may be greater than the angle Θ3b between the guide wall 221 and the radial direction of the second body 2. A difference between the angle Θ3a, which is formed by the outlet grille 18 and the radial direction of first body 1, and the angle Θ3b, which is formed by the guide wall 221 and the radial direction of the second body 2, may decrease toward the edge of the guide wall 221.
The outlet cover may be the outlet grille 18. The outlet grille 18 may consist of a plurality of vanes 181.

The outlet grille 18 may be connected to the holder wall 191. The outlet grille 18 may be connected to the holder edge 194. The holder wall 191 may be formed higher than the height of a circumferential surface of the first body 1. The holder edge 194 may be positioned above the housing edge 161. The outlet grille 18 may be connected to the holder edge 194 and the housing edge 161. The vane 181 may be connected to the holder edge 194 and the housing edge 161. For example, the holder edge 194 may be formed higher than the housing edge 161, and the vane 181 may be obliquely connected from the holder edge 194 located at an upper position to the housing edge 161 located at a lower position.
The lower cover 22 may be connected to the holder edge 194. The lower cover 22 may extend from the holder edge 194. The guide wall 221 may extend outward from the holder edge 194 in the lateral direction. The outlet grille 18 and the guide wall 221 may be connected to form an acute angle at the holder edge 194. For example, the outlet grille 18 that is inclined downward toward the outside of the first body 1 and the guide wall 221 that is inclined upward toward the outside of the first body 1 may be connected at the holder edge 194 and may form an acute angle.
The second body 2 may include the post 21 that may be inserted into the holder 19 of the first body 1. The post 21 may have a shape corresponding to that of the opening defined by the holder 19, and may be smaller than the holder 19. The post 21 of the second body 2 may be inserted into and fixed to the holder 19. The holder wall 191 may be in contact with an outer surface of the post 21. For example, the post 21 may be formed in substantially cylindrical shape that is smaller than the holder 19, so as to be received in and fixed to the holder 19.
The holder 19 may include a guide column 193 to guide a coupling direction of the post 21. The guide column 193 may be disposed inside the holder 19. The guide column 193 may be formed on an inner wall of the holder 19. The guide column 193 may be provided in plurality. For example, a plurality of guide columns 193 may be in contact with the inner wall of the holder 19, and may be spaced apart from each other to be disposed at opposite positions. The pole 21 may include a recess to receive the guide column 193.
