연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

The present invention is an air purifier including an ionizing assembly that operates to charge particulate material in an air flow passing through the purifier. The charged particulate material is attracted to and retained by a filter element disposed downstream of the ionization assembly and having an electrical charge opposite to the charged particulate material. The purified air passing through the filter is directed out of the device, optionally in conjunction with a fragrance that is added to the purified air flow. The ionizing assembly is formed with a ground member disposed adjacent the ionizing member to keep the electrons generated by the ionizing assembly within the purifier, and thus prevent static discharges from occurring outside of the purifier. The air flow is directed by a fan through the purifier in an angular and substantially laminar manner, such that the efficiency of the purifier is increased.

What is claimed is: 1. An air purifier comprising a housing defining an inlet, an outlet spaced from the inlet, and an air flow path extending between the inlet and the outlet, the air flow path including a straight section extending from one of the inlet or the outlet, and an angled section extending from the straight section towards the other of the inlet or the outlet, wherein the angled section defines an angle with respect to the straight section that optimizes the purification of air moving through the device along the air flow path and a baffle disposed within the air flow path at the intersection of the straight section and the angled section wherein the baffle includes a narrow end connected to the housing and a wide end located opposite the narrow end and disposed within the air flow path. 2. An air purifier comprising a housing defining an inlet, an outlet spaced from the inlet, and an air flow path extending between the inlet and the outlet, the air flow path including a straight section extending from one of the inlet or the outlet, and an angled section extending from the straight section towards the other of the inlet or the outlet, wherein the angled section defines an angle with respect to the straight section that optimizes the purification of air moving through the device along the air flow path and a baffle disposed within the air flow path at the intersection of the straight section and the angled section wherein the baffle includes a narrow end connected to the housing and a wide end located opposite the narrow end and disposed within the air flow path, wherein the baffle is formed of an elongate planar member having a pair of opposed ends and a pair of opposed sides extending between the pair of opposed ends, wherein the pair of opposed ends form the narrow end and are secured to the housing generally perpendicular to the air flow path. 3. An air purifier comprising a housing defining an inlet, an outlet spaced from the inlet, and an air flow path extending between the inlet and the outlet, the air flow path including a straight section extending from one of the inlet or the outlet, and an angled section extending from the straight section towards the other of the inlet or the outlet, wherein the angled section defines an angle with respect to the straight section that optimizes the purification of air moving through the device along the air flow path and a baffle disposed within the air flow path at the intersection of the straight section and the angled section wherein the angled section forms an angle of between about 20° to about 60° with respect to the straight section. 4. The air purifier of claim 3 further comprising an ionizing mechanism disposed within the housing across the air flow path, the ionizing mechanism including a first ionizing assembly having a pin assembly disposed within the air flow path, and a ground member disposed around the pin assembly along the periphery of the air flow path upstream of the pin assembly. 5. An air purifier comprising a housing defining an inlet, an outlet spaced from the inlet, and an air flow path extending between the inlet and the outlet, the air flow path including a straight section extending from one of the inlet or the outlet, and an angled section extending from the straight section towards the other of the inlet or the outlet, wherein the angled section defines an angle with respect to the straight section that optimizes the purification of air moving through the device along the air flow path and a baffle disposed within the air flow path at the intersection of the straight section and the angled section wherein the angled section forms an angle of between about 20° to about 60°with respect to the straight section, further comprising an ionizing mechanism disposed within the housing across the air flow path, the ionizing mechanism including a first ionizing assembly having a pin assembly disposed within the air flow path, and a ground member disposed around the pin assembly along the periphery of the air flow path upstream of the pin assembly and further comprising an air movement mechanism disposed in the housing across the air flow path, the air movement mechanism including: a) a mounting frame having a central portion, a number of support arms extending outwardly from the central portion and an outer ring connected to the support arms and spaced from the central portion; b) an impeller rotatably mounted to the central portion; and c) a second ionizing assembly secured to the mounting frame, the second ionizing assembly including a conducting base member mounted to the ring, at least one first pin extending radially inwardly from the base member, and at least one second pin mounted to the central portion. 6.
