Description
본 발명은, 배기순환 진공청소기에 관한 것으로서, 보다 상세하게는, 흡입구의 양측 단부영역의 이물질을 용이하게 흡입할 수 있도록 한 배기순환 진공청소기에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an exhaust circulation vacuum cleaner, and more particularly, to an exhaust circulation vacuum cleaner in which foreign substances in both end regions of an intake port can be easily sucked.
일반적으로 진공청소기는, 흡입구 및 배기구가 형성되어 있는 케이싱과, 케이싱의 내부에 수용되어 흡입력을 발생시키는 흡입팬과, 흡입팬의 흡입측에 배치되어 유체와 함께 흡입된 이물질을 차단하는 필터부재를 구비한다.In general, a vacuum cleaner includes a casing having a suction port and an exhaust port, a suction fan accommodated in the casing to generate suction force, and a filter member disposed at the suction side of the suction fan to block foreign substances sucked with the fluid. Equipped.
배기순환 진공청소기는, 흡입팬으로부터 배출되는 유체중의 적어도 일부를 흡입측으로 순환되도록 한 진공청소기의 일종이다.The exhaust circulation vacuum cleaner is a kind of vacuum cleaner in which at least a part of the fluid discharged from the suction fan is circulated to the suction side.
도 1은 종래의 배기순환 진공청소기의 종단면도이다. 도시된 바와 같이, 배기순환 청소기는, 내부에 수용공간이 형성되어 있는 본체케이싱(111)과, 본체케이싱(111)의 하측에 배치되는 흡입케이싱(113)과, 본체케이싱(111)의 내부에 수용되는 흡입팬(115)과, 흡입팬(115)의 흡입측에 배치되어 내부에 이물질을 수용하게 되는 필터부재(117)를 포함하여 구성되어 있다. 본체케이싱(111)의 상부영역에는 손잡이(119)가 상향연장되도록 형성되어 있으며, 필터부재(117)의 상측에는 제어부(121)가 구비되어 있다.1 is a longitudinal cross-sectional view of a conventional exhaust circulation vacuum cleaner. As illustrated, the exhaust circulation cleaner includes a main body casing 111 in which an accommodation space is formed, a suction casing 113 disposed under the main body casing 111, and a main body casing 111. It comprises a suction fan 115 to be accommodated, and a filter member 117 disposed on the suction side of the suction fan 115 to accommodate the foreign matter therein. The upper portion of the main body casing 111 is formed so that the handle 119 is extended upward, the control unit 121 is provided on the upper side of the filter member 117.
한편, 흡입케이싱(113)의 저부에는 외부로부터 유체를 흡입할 수 있도록 외부와 연통되게 흡입구(123)가 형성되어 있으며, 흡입구(123)에는 외부로부터 흡입된 유체가 자루형상을 가지는 필터부재(117)의 내부로 유입될 수 있도록 흡입로(125)가 형성되어 있다. 흡입팬(115)의 일측에는 흡입팬(115)으로부터 배출된 유체를 흡입구(123)측으로 순환시킬 수 있도록 배기순환로(127)가 형성되어 있다.Meanwhile, a suction port 123 is formed at the bottom of the suction casing 113 to communicate with the outside so as to suck the fluid from the outside, and the suction port 123 has a filter member 117 having a bag shape. Suction passage 125 is formed to be introduced into the inside of). An exhaust circulation path 127 is formed at one side of the suction fan 115 to circulate the fluid discharged from the suction fan 115 toward the suction port 123.
이러한 구성에 의하여, 제어부(121)에 의해 흡입팬(115)이 구동되면 흡입구(123)를 통해 외부로부터 유체 및 이물질이 흡입되고, 흡입된 유체 및 이물질은 필터부재(117)의 내부로 유입된다. 이물질은 필터부재(117)의 내부에 수집되고, 유체는 필터부재(117)를 통과하여 흡입팬(115)을 경유하여 배기순환로(127)를 따라 유동하게 된다. 흡입구(123)영역으로 순환된 유체는 흡입케이싱(113)의 외부로부터 흡입된 유체와 함께 다시 흡입로(125)를 따라 흡입되고 배기순환로(127)를 통해 순환되는 동작을 반복하면서 순환되어 이물질을 흡입제거하게 된다.By this configuration, when the suction fan 115 is driven by the control unit 121, the fluid and foreign matter is sucked from the outside through the suction port 123, the sucked fluid and foreign matter is introduced into the filter member 117. . The foreign matter is collected in the filter member 117, the fluid passes through the filter member 117 and flows along the exhaust circulation path 127 via the suction fan 115. The fluid circulated to the suction port 123 is circulated with the fluid sucked from the outside of the suction casing 113 again along the suction path 125 and circulated through the exhaust circulation path 127 to remove foreign substances. Inhalation will be removed.
그런데, 이러한 종래의 배기순환 진공청소기에 있어서는, 흡입구(123)의 길이방향을 따라 흡입구(123)의 중앙영역에 비해 양측 단부영역은 흡입력이 상대적으로 미약하기 때문에 이물질을 충분히 흡입/제거할 수 없다고 하는 문제점이 있다.However, in such a conventional exhaust circulation vacuum cleaner, since the suction force of both side end regions is relatively weak compared to the central region of the inlet 123 along the longitudinal direction of the inlet 123, foreign substances cannot be sufficiently sucked / removed. There is a problem.
따라서, 본 발명의 목적은, 흡입구의 양측 단부영역의 이물질을 용이하게 흡입할 수 있는 배기순환 진공청소기를 제공하는 것이다.Accordingly, it is an object of the present invention to provide an exhaust circulation vacuum cleaner which can easily inhale foreign matters at both end regions of the intake port.

At this time, the inside of the ejector chamber part 41 has a relatively low pressure, so that fluid and foreign substances in one end region of the suction nozzle 23 are transferred into the ejector chamber part 41 through the ejector chamber suction pipe 47. Is inhaled.
이젝터체임버부(41)의 내부로 흡입된 유체 및 이물질은 확장관(42)의 내부로 유입되어 이젝터노즐부(43)를 통해 분사되는 유체와 함께 이젝터체임버배출관(45)을 통해 흡입노즐(23)의 타측 단부영역으로 분사됨으로써, 상대적으로 흡입력이 미약한 흡입노즐(23)의 단부영역의 이물질을 중앙영역으로 유동시켜 흡입이 용이하게 이루어지도록 한다.The fluid and foreign matter sucked into the ejector chamber part 41 are introduced into the expansion pipe 42 and the suction nozzle 23 through the ejector chamber discharge pipe 45 together with the fluid sprayed through the ejector nozzle part 43. By spraying to the other end region of), foreign matter in the end region of the suction nozzle 23 having relatively low suction force flows to the central region so that the suction can be easily performed.
이상 설명한 바와 같이, 본 발명에 따르면, 흡입팬으로부터 배출되는 유체중의 일부를 순환시키는 배기순환관과, 배기순환관의 말단에 배치되어 유체를 고속으로 분사하는 이젝터노즐부와, 이젝터노즐부의 둘레에 배치되어 내부에 저압영역을 형성하는 이젝터체임버부와, 일단이 이젝터체임버부의 유출측에 연결되고 타단은 흡입노즐의 일측 단부에 연결되는 이젝터체임버배출관과, 일단은 이젝터체임버에 연통되게 연결되고 타단은 흡입노즐의 단부에 연결되는 이젝터체임버흡입관을 마련함으로써, 흡입력이 상대적으로 미약한 흡입구의 양측 단부영역의 이물질을 용이하게 흡입할 수 있도록 한 배기순환 진공청소기가 제공된다.As described above, according to the present invention, an exhaust circulation tube for circulating a part of the fluid discharged from the suction fan, an ejector nozzle portion disposed at the end of the exhaust circulation tube for injecting the fluid at high speed, and a circumference of the ejector nozzle portion An ejector chamber portion disposed at the inner side to form a low pressure region therein; an ejector chamber discharge tube having one end connected to an outlet side of the ejector chamber portion; and the other end connected to one end of the suction nozzle; and one end connected to the ejector chamber and the other end By providing an ejector chamber suction pipe connected to the end of the suction nozzle, an exhaust circulation vacuum cleaner is provided to facilitate the suction of foreign matter at both end regions of the suction port with a relatively low suction force.
