Description

vacuum cleaner

The present invention relates to a vacuum cleaner, and more particularly, to a portable vacuum cleaner with improved convenience.

2. Description of the Related Art In general, a vacuum cleaner is a household appliance that sucks in small garbage or dust in a manner that uses electricity to suck air and fills the dust bin in the product, and is generally referred to as a vacuum cleaner.

Such a vacuum cleaner may be divided into a manual cleaner in which a user directly moves the cleaner and performs cleaning, and an automatic cleaner in which the user performs cleaning while driving by themselves. Manual vacuum cleaners may be classified into canister-type cleaners, upright cleaners, handy-type cleaners, stick-type cleaners, and the like, depending on the type of cleaner.

In the past, canister-type vacuum cleaners were used a lot in household cleaners, but recently, hand-held vacuum cleaners and stick cleaners, which are convenient to use by providing a dust container and a cleaner body, are increasingly used.

The canisty type vacuum cleaner is connected to the main body and the suction port by a rubber hose or pipe, and in some cases, it can be used by inserting a brush into the suction port.

The Hand Vacuum Cleaner maximizes portability, and since it is light in weight but short in length, there may be restrictions on the cleaning area while sitting. Therefore, it is used to clean localized places such as on a desk or sofa, or in a car.

The stick vacuum cleaner can be used while standing, so you can clean without bending your back. Therefore, it is advantageous for cleaning while moving a large area. If a hand-held vacuum cleaner cleans a narrow space, the stick-type vacuum cleaner can clean a wider space than that, and can clean a high place that cannot be reached by hand. Recently, a stick cleaner is provided in a module type, and the cleaner type is actively changed and used for various objects.

Meanwhile, the cleaner may be classified into a wet cleaning method or a dry cleaning method according to a cleaning method. The wet cleaning method is a method of cleaning the cleaning area by spraying water or steam or cleaning the cleaning area with a wet rag. The dry cleaning method is a method of cleaning the cleaning area by sucking in dust or scrubbing with a brush.

On the other hand, there is a wet mop equipped with a steamer for generating steam among the wet mops. The steamer includes a tank for storing water therein, and vaporizes the water stored in the tank to generate steam. The steam wet mop supplies the generated steam to the mop, sterilizes the mop with steam, and sterilizes bacteria and the like existing on the floor with high-temperature steam.

Prior Document 1 relates to a steam and vacuum combined cleaner. Prior Document 1 shows a vacuum cleaner capable of steam cleaning and dust suction.

The cleaner may combine a steam cleaner and a vacuum cleaner, and is configured to supply power from the steam cleaner to the vacuum cleaner.

According to Prior Document 1, when dry cleaning is performed, the vacuum suction unit is separated from the main body, and the cleaning area is cleaned while carrying the vacuum suction unit. However, in order to carry the vacuum suction unit, a separate handle must be provided, and the separate handle has to be provided at a position other than the connection part with the main body in the vacuum suction unit, and there is a spatial limitation. In addition, the shape of the handle also has a problem in that it is impossible to design an ergonomic design suitable for a user in order to make the entire vacuum cleaner compact, and it must be formed in a simple shape such as a ring.

In addition, when performing wet cleaning, the vacuum suction unit provided with the battery should always be coupled to the cleaner body. Accordingly, there is a problem in that the overall weight of the cleaner is increased due to the suction motor disposed in the vacuum suction unit, which is inconvenient, and there is also a problem in that the size of the entire cleaner is increased due to the volume of the vacuum suction unit itself.

Prior Document 2 relates to a rotary mop cleaner capable of adjusting the rotational speed. Prior Document 2 discloses a wet mop cleaner in which a main battery is provided in a cleaning module and an auxiliary battery is detachably coupled to an extension tube.

However, Prior Document 2 does not include a dry cleaning module for dry cleaning. Even in the case of combining Prior Document 1 with Prior Document 2, a compact cleaner having a wet cleaning module and a dry cleaning module in addition to additionally providing a separate battery or additionally forming a dust accommodating part in the cleaner body of Prior Document 1 cannot present

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

First, the main components of the cleaner 100 will be briefly described.

1 is a perspective view of a cleaner 100 according to the present invention.

The cleaner 100 may mean a cleaner manually operated by a user. For example, the cleaner 100 may mean a handheld cleaner or a stick cleaner.

The cleaner 100 may include a body 110 . The body 110 is provided with a suction motor 114 therein, and is a component that provides suction power during dry cleaning.

The body 110 is detachably coupled to the cleaning module 160 . Specifically, the main body 110 may be directly coupled to the cleaning module 160 , or may be coupled indirectly through the extension pipe 150 . The suction part 112 of the main body is coupled to the cleaning module 160 or the extension pipe 150 . For example, the main body 110 may be coupled to the cleaning module 160 during dry cleaning, and the main body 110 may be separated from the cleaning module 160 during wet cleaning.

When the suction port is formed in the cleaning module 160 , the suction motor 114 provides suction force to the cleaning module 160 . When the cleaning module is divided into a wet cleaning module 160 shown in the drawing and a dry cleaning module (not shown) not shown, the suction motor 114 provides suction power to the dry cleaning module.

The body 110 may be connected to the extension tube 150 . The body 110 may be connected to the cleaning module 160 through the extension pipe 150 . During dry cleaning, the main body 110 may generate suction force through the suction motor 114 , and may provide suction force to the cleaning module 160 through the extension pipe 150 . In this case, external dust may be introduced into the main body 110 through the cleaning module 160 and the extension pipe 150 .

The body 110 forms an external shape and accommodates the main components therein. The main body 110 may include a suction unit 111 , a discharge unit 112 , a dust separation unit (not shown), a suction motor 114 , and a filter (not shown).

A center line A1 is defined with reference to FIG. 1 . Referring to FIG. 1 , an imaginary center line A1 passing through the center of the extension pipe 150 may be formed. The center line A1 is disposed in the longitudinal direction of the extension pipe 150 . The center line A1 may have a variable angle according to a user's manipulation.

When viewed from the front, the center line A1 may be the center of gravity of the cleaner 100 . The suction motor 114 and the first battery 140 are disposed along the center line A1 of the cleaner body 110 . Accordingly, the center of gravity of the cleaner body 110 is disposed on the center line A1. By having such an arrangement, since the cleaner 100 is not tilted to one side, the user can easily operate the cleaner 100 .

The suction unit 111 is a hole through which air containing dust is introduced into the body 110 during dry cleaning.

Referring to FIG. 1 , the suction part 111 is coupled to the extension pipe 150 . Alternatively, although not shown, the suction unit 111 may be directly coupled to the cleaning module 160 .

The discharge part 112 is a hole through which the dust inside the main body 110 is discharged to the outside during dry cleaning.

Referring to FIG. 1 , the discharge part 112 is formed on the upper surface of the body 110 .

The suction unit 111 and the discharge unit 112 may be formed in different directions. Specifically, the suction unit 111 may be disposed toward the front of the main body 110 , and the discharge unit 112 may be disposed toward the upper side of the body 110 .

The dust separation unit (not shown) communicates with the extension pipe 150 . The dust separator may separate dust sucked into the inside through the extension pipe 150 .

The dust separator may communicate with the dust container 120 . More specifically, the dust separation unit may be disposed inside the dust container 120 . Accordingly, the dust separated by the dust separation unit is collected in the dust container 120 , and the air is discharged to the outside of the dust separation unit.

The dust separator may be a cyclone capable of separating dust by cyclone flow. Accordingly, air and dust sucked in through the extension pipe 150 helically flow along the inner circumferential surface of the dust separation unit. Accordingly, a cyclone flow may occur based on the central axis of the dust separation unit.

The suction motor 114 is a component that generates a suction force for sucking air.

Referring to FIG. 1 , the suction motor 114 is accommodated in the body 110 . The suction motor 114 generates suction force by rotation.

Referring to FIG. 1 , the suction motor 114 is disposed above the dust container 120 . By having such an arrangement, some dust from the air sucked in by the suction motor 114 is collected in the dust container 120 by gravity, and the lifespan of the suction motor 114 is increased.

Referring to FIG. 1 , the suction motor 114 is disposed downstream of the dust container 120 . By having this arrangement, the air filtered from the dust container 120 passes through the suction motor 114 . Accordingly, there is an effect that the lifespan of the suction motor 114 is increased compared to that the suction motor 114 is disposed upstream of the dust container 120 .

A filter (not shown) is a component that filters foreign substances contained in the flowing air. The filter may include a pre-filter or a HEPA filter.

The pre-filter is a filter disposed at the most upstream of the filters, and is formed in a mesh shape to primarily filter large particles of dust. The pre-filter is a component that physically filters out dust larger than the mesh spacing and improves the life of other filters.

HEPA filter is an abbreviation for High Efficiency Particulate Air (HEPA) and is a component that filters fine dust. In general, HEPA filters filter fine dust by electrostatic force. The HEPA filter filters fine dust included in the dust introduced from the dust container 120 , and blocks the fine dust from being discharged to the outside of the cleaner 100 . The HEPA filter is placed downstream of the pre-filter to improve lifespan.

The filter may be disposed downstream of the suction motor 114 . The filter may be disposed upstream or downstream of the suction motor 114 . However, referring to FIG. 1 , the filter is preferably disposed downstream of the suction motor 114 , that is, above the suction motor 114 . This is for the user to easily replace the filter.
