Description

Upright Vacuum Cleaner {A UPRIGHT TYPE VACUUM CLEANER}

The present invention relates to an upright type vacuum cleaner, and more particularly, to an upright type vacuum cleaner for cooling a power cord.

In general, a vacuum cleaner refers to a device that separates dust from a dust collecting unit by sucking air including dust on a surface to be cleaned and discharges purified air to the outside. In order to supply power to the vacuum cleaner, the vacuum cleaner is provided with a cord reel assembly in which a power cord is wound. Since heat is generated from the power cord as the vacuum cleaner is used, the vacuum cleaner has a structure that cools the heat generated from the power cord by allowing the air discharged from the suction motor to be discharged to the outside after passing through the cord reel assembly.

However, the air discharged from the intake motor contains impurities such as carbon powder from the carbon brush of the intake motor, resulting in a problem of contaminating the power cord.

For this problem, Japanese Patent Application Laid-Open No. 07-124082 and US Patent No. US6052862 disclose that the air discharged from the intake motor is purged again through an exhaust filter and then cooled by a power cord wound on the cord reel assembly, and then outside the vacuum cleaner. Disclosed is a structure that is discharged.

However, Japanese Patent Application Laid-Open No. 07-124082 does not have a structure in which the exhaust filter is separated from the vacuum cleaner body in order to clean the exhaust filter. Therefore, the exhaust filter cannot be cleaned, and US Patent No. US6052862 describes the exhaust filter in the vacuum cleaner body. In order to separate from the cord reel assembly, the user has access to the exhaust filter only when the cord reel assembly has to be separated from the cleaning main body, which is inconvenient to clean the exhaust filter.

The present invention is to solve the conventional problems as described above, in the vacuum cleaner having a structure in which the air purified through the exhaust filter to cool the power cord through the cord reel assembly, an upright that can easily clean the exhaust filter The purpose is to provide a vacuum cleaner.

In addition, an object of the present invention is to provide an upright type vacuum cleaner which also serves as a duct that switches the movement direction of the exhaust flow path while the exhaust filter cover covers the exhaust filter.

The present invention for achieving the above object is provided with a motor chamber equipped with a suction motor, the cleaning main body having a front, two sides and a rear; An exhaust filter unit installed on one surface of the cleaning body and filtering impurities from air discharged from the suction motor; And a cord reel assembly including a power cord installed on the other side of the cleaning main body, wherein one side of the cleaner body in which the exhaust filter unit is installed and the other side of the cleaner body in which the cord reel assembly is installed are different sides. The exhaust air discharged from the exhaust filter unit may change direction to pass through the cord reel assembly, cool the power cord, and exit the cord reel assembly.

In addition, the exhaust filter unit is installed on the side of the cleaning main body, the cord reel assembly is installed to be in communication with each other adjacent to the rear of the cleaning main body, or the exhaust filter unit is installed on the rear of the cleaning main body The cord reel assembly is configured to be adjacent to and communicate with each other on the side of the cleaning base.

In addition, the exhaust filter assembly, the exhaust filter receiving portion; A filter member mounted to the exhaust filter accommodating part; And an exhaust filter cover for selectively opening the exhaust filter accommodating part, wherein one side of the exhaust filter accommodating part has a hinge part rotatably connected to the exhaust filter accommodating part, and the other side of the exhaust filter cover is exhausted. In order to selectively lock the filter accommodating portion, it is preferable that a pair of locking portions are provided to be spaced apart from each other.

In addition, the exhaust filter cover has an extension portion between the pair of locking portions, and in the state in which the exhaust filter cover closes the exhaust filter accommodating portion, the extension portion is turned at right angles to the direction of the purified air passing through the filter member. Preferably, the duct flow path is formed to move inside the cord reel assembly.

In addition, a first communication port communicating with the motor chamber is formed below the exhaust filter accommodating part, and a second communication part communicating with the inside of the cord reel assembly at a position corresponding to the extension part is provided at a side of the exhaust filter accommodating part. It can be configured to form a sphere.

In addition, a first communication port communicating with the motor chamber is formed at a lower portion of the exhaust filter accommodating part, and a second communication part communicating with an inside of the cord reel assembly at a position corresponding to the extension part is formed at a rear surface of the cord reel assembly. It can be configured to form a sphere.

In addition, the exhaust filter unit preferably serves to remove impurities in the air discharged from the intake motor and to switch the flow of the purified exhaust air from which the impurities are removed.

In addition, the exhaust filter unit and the cord reel assembly may be installed to protrude from the cleaner body.

According to the above, the present invention can remove and clean the filter member 134 from the vacuum cleaner only by rotating the exhaust filter cover 133 to open the exhaust filter accommodating part 131, so that the exhaust air is more convenient than the conventional method. The filter can be cleaned.

In addition, an extension part 138 is integrally formed in the exhaust filter cover 133 of the present embodiment, so that the exhaust filter cover 133 covers the filter member 134 as well as the cord reel from the exhaust filter unit 130. Since the duct acts as a duct for converting the flow of air moving to the assembly 150, the number of parts can be reduced because a separate flow path is not required.

Hereinafter, an upright type vacuum cleaner 100 according to a first embodiment of the present invention will be described with reference to the drawings.

1 to 2, the present invention includes a cleaning base 101, a nozzle assembly 110, a dust collecting unit 120, an exhaust filter unit 130, and a cord reel assembly 150.

The cleaning main body 101 has a handle portion 108 formed at the upper portion, a dust collecting unit 120 is installed at the front side, and the nozzle assembly 110 is installed at the lower portion to be rotatable.
