Benefits of technology

[0009] An object of the present invention is to provide a vacuum cleaner that has a structure in which air circulates back to a vacuum cavity of a vacuum head by air suctioning and discharging forces generated by a blower motor, while at the same time using the principle of a venturi to cause ozone to infiltrate a surface that is being cleaned for a sterilizing and disinfecting effect.
[0010] Another object of the present invention is to provide a vacuum cleaner capable of maximizing its sterilizing and disinfecting effectiveness by discharging ozone through an air pump to clean a surface below the suctioning head.

Problems solved by technology

Accordingly, in such devices relying on this structure employing vacuuming force to discharge ozone into the vacuum cavity, the ozone cannot effectively reach the carpet, so that effective removal of mites and germs from the carpet is not possible.
Also, to increase suctioning power, conventional vacuum cleaners use large capacity-blowers, resulting in increased noise and power consumption as well as increased discharge of fine dust particles.

first embodiment

[0021]FIG. 1 is a perspective view showing the structure of a vacuum cleaner according to the first embodiment of the present invention, FIG. 2 is a sectional view of a vacuum cleaner according to the first embodiment of the present invention, showing ozone and air flow paths, and FIG. 3 is sectional view of a suctioning head according to the first embodiment of the present invention.

[0022] A vacuum cleaner 10A according to the first embodiment of the present invention is structured in an air circulating configuration that discharges ozone from the suctioning cavity 31 of the suctioning head 30 by means of the air flow speed through the circulating passages of the vacuum cleaner.

[0023] Within the hose 40 connecting the main body 20 of the vacuum cleaner to the suctioning head 30, an air discharging passage 41 is separated from an air suctioning passage 42.

[0024] The air discharging passage 41 and the air suctioning passage 42 may be flexible hoses separately installed in the hose...

second embodiment

[0035] The second embodiment according to the present invention is illustrated in FIG. 4.

[0036] Referring to FIG. 4, one air suctioning passage 42 is provided to connect the main body 20 of the vacuum cleaner to the suctioning head 30 thereof, and an ozone generator 50 that generates ozone and an air pump 100 for pumping the ozone generated by the ozone generator 50 to a suctioning cavity 31 of the suctioning head 30 are provided on the suctioning head 30.

[0037] The air pump 100 is compact and is rechargeable or is powered from the main body 20 through an electrical connection therewith.

[0038] Here, the ozone generator 50 and the air pump 100 may be separately or integrally formed.

[0039] The air suctioning blower 60 is installed in the main body 20, and the suctioning port of the air suctioning blower 60 is connected to the air suctioning passage 42. The air suctioned by the air suctioning blower 60 is discharged through a discharge port 22 of the main body 20.

Abstract

A vacuum cleaner capable of reducing noise, power consumption, and the discharging of fine dust particles, and eradicating mites, mold, and germs by blowing ozone is provided. The vacuum cleaner includes a main body, suctioning head, hose, ozone generator, and venturi. The main body includes an air suctioning blower installed within to impart suctioning force. The suctioning head includes a suctioning cavity. The hose connects the main body to the suctioning head, and includes an air discharging passage divided from an air suctioning passage. The ozone generator generates ozone and is installed on the suctioning head. The venturi connects a discharging end of the ozone generator to the air discharging passage. The suctioning force continuously circulates air through the air discharging passage, the suctioning cavity, and the air suctioning passage, and the ozone generated by the ozone generator is supplied to the suctioning cavity through the venturi.

Description

CROSS REFERENCE [0001] Applicant claims foreign priority under Paris Convention and 35 U.S.C. ยง 119 to a Korean Patent Application No. 10-2005-0104854, filed Nov. 3, 2005 with the Korean Intellectual Property Office. BACKGROUND OF THE INVENTION [0002] 1. Field of the Invention [0003] The present invention relates to a vacuum cleaner, and more particularly, to a vacuum cleaner capable of reducing noise and power consumption, reducing the discharging of fine dust particles, and eradicating mites, mold, and germs by blowing ozone. [0004] 2. Description of the Related Art [0005] Ozone, as a sterilizing and disinfecting agent, when applied to vacuum cleaners, can eradicate mites and various germs on carpets and other surfaces. For this purpose, ozone generators are installed on the main bodies or suctioning heads of vacuum cleaners in the related art. The ozone generated from the ozone generators is discharged through a vacuum cavity by means of the vacuuming force. [0006] Accordingly, i...
