Air Purifier

This application claims the benefit of and priority to Korean Patent Application No. 10-2024-0077097, filed in Korea on Jun. 13, 2024, the entire disclosure(s) of which is hereby incorporated herein by reference in its entirety.

The present disclosure relates to an air purifier, and more particularly, to an air purifier including a booster.

An air purifier is a device that filters and discharges air inside a predetermined space to reduce dust and bacteria in the air in the corresponding space. The air purifier filters out foreign substances through an air flow in the corresponding space and discharges air from which the foreign substance is removed.

In order to suck the air in a wide range of the corresponding space and to discharge the filtered air, it is possible to initiate a structure of forming an inlet on a circumference surface of a cylindrical case, and discharging the filtered air to the top. However, a device which switches a separate flow to a top to which the filtered air is discharged is provided in order to discharge the filtered air to a long-distance area of the corresponding space to discharge the filtered air to a wide area of an indoor space.

Korean Patent Unexamined Publication No. 10-2018-0000121 discloses a blowing device which flows the air to the top from a lower circumferential surface, and a booster which is disposed above the blowing device and switches the flow of the air discharged to the top.

However, such a structure as a coupling body having a complicated structure is a structure in which it is difficult for a user to arbitrarily separate the booster. Accordingly, there is a problem in that it is difficult for the user to directly manage the booster itself.

In view of the above, the present disclosure solves the above-described problems and other problems.

Another object of the present disclosure is to provide an air purifier including a booster which is enabled to be managed by a user.

Yet another object of the present disclosure is to provide an air purifier which is enabled to manage a fan assembly inside the booster.

Still yet another object of the present disclosure is to provide an air purifier in which the booster is easily separated and coupled.

Still yet another object of the present disclosure is to provide an air purifier including a booster which stably maintains a coupling state.

In order to achieve the objects, the present disclosure provides an air purifier including: a body having an inlet formed on a circumferential surface thereof and an outlet formed on an upper surface thereof; and a booster disposed onthe body and switching a flow direction of air which flows from the body through the outlet.

The booster includes a booster case having a booster inlet and a booster outlet, a booster fan disposed in the booster case, and forming air flowing from the booster inlet to the booster outlet, and a fan housing in which the booster fan is rotatably disposed.

The booster case includes a circumference body disposed on a circumference of the fan housing and guiding air discharged from the fan housing, and a rear body disposed at one side of the circumference body and having the booster inlet.

The fan housing is coupled to the rear body by penetrating the circumference body.

The circumference body is hook-coupled to the rear body.

The circumference body includes a circumference wall disposed on the circumference of the fan housing, and a rear wall extended to an inner side in a rear of the circumference wall.

A penetration hole penetrated by a partial configuration of the fan housing or the rear body is formed on the rear wall.

The fan housing includes a fastening boss which protrudes to a rear on a rear surface of the fan housing.

The fastening boss is coupled to the rear body by penetrating the penetration hole.

The fan housing includes a locking jaw which protrudes to the rear on the rear surface of the fan housing, and is banded to an upper side.

The locking jaw is inserted into a locking groove formed in the circumference body.

The fan housing includes a terminal connector disposed to be spaced apart from the locking jaw and electrically connected to the body.

A connection hole penetrated by the terminal connector is formed in the circumference body.

The terminal connector is disposed in an opposite direction to the locking jaw.

A direction in which the terminal connector protrudes from the fan housing is formed to be different from a direction in which the locking jaw protrudes from the fan housing.

The terminal connector is banded in an opposite direction to a direction in which the terminal connector is disposed.

The fan housing has a fan suction port formed in a direction of the rear body and a fan discharge port formed in a direction of the circumference.

A booster connector coupled to the body is disposed in the circumference body.

The rear body has an opening formed in an area where the booster connector is disposed.

The rear body has a shape of being convex to the rear.

An inner surface of the rear body includes a contact rib which protrudes to the circumference body.

The fan housing includes a locking jaw which protrudes to a rear of the circumference body through a locking groove formed in the circumference body.

The contact rib is disposed to be in contact with one side of the locking jaw.

The booster is separably disposed at an upper portion of the body.

When the booster and the booster coupler are coupled to each other, the booster is electrically connected to the body.

Details of other embodiments will be included in the detailed description and the accompanying drawings.

According to the air purifier of the present disclosure, there are one or more following effects.

First, there is also an advantage in that through a structure in which a booster is separated from a booster, a user can easily manage the booster.

Second, a rear body is separated from a fan housing to separate the rear body including a circumference body. That is, there is an advantage in that the user can easily manage an inner part of the booster.

Third, when a booster case is separated, a part of a booster fan can be exposed to the outside. Accordingly, there is an advantage in that the user can manage the booster fan.

Fourth, a state in which a plurality of components of the booster are coupled in a fastening and coupling structure between the plurality of components of the booster can be firmly maintained. That is, since the booster stably maintains the coupling state, air can be stably supplied in an inclined direction at an upper side by a body.

The effects of the present disclosure are not limited to the aforementioned effect, and other effects, which are not mentioned above, will be apparent to a person having ordinary skill in the art from the description of the claims.

Advantages and features of the present disclosure, and methods for accomplishing the same will be more clearly understood from embodiments described in detail below with reference to the accompanying drawings. However, the present disclosure is not limited to embodiments disclosed below but may be implemented in various different forms. However, the exemplary embodiments are provided to make the present disclosure be complete and completely announce the scope of the present disclosure to those skilled in the art to which the present disclosure belongs and the present disclosure is just defined by the scope of the claims. The present disclosure is just defined by the scope of the claims. Throughout the present disclosure, the same reference numerals denote the same elements.
