Description

  The present invention relates to a vacuum cleaner, and more particularly to an inlet assembly of a vacuum cleaner into which dust on a surface to be cleaned is sucked.

  Usually, the vacuum cleaner is a device that sucks in dust on the surface to be cleaned by using a suction input generated by driving a vacuum source stored in the main body.

  The vacuum cleaner includes a vacuum cleaner main body in which a motor that generates a vacuum force is stored, a suction inlet assembly that sucks dust facing a surface to be cleaned, and the vacuum cleaner that sucks dust sucked from the suction inlet assembly. And an extension channel leading to the machine body. The extension flow path includes an extension pipe connector that is fluidly coupled to the suction port assembly, an extension pipe connected to the extension pipe connector, and a suction hose communicating with the extension pipe.

  Referring to FIGS. 1A and 1B, the suction port assembly includes an upper housing 10 and a lower housing 11, and a suction port 14 through which dust is sucked from a surface to be cleaned is formed in the lower housing 11. Further, the lower housing 11 is provided with side dust moving channels 12 from both sides of the suction port 14, and the dust on the side (S) of the suction port assembly is sucked through the side dust moving channels 12. 14 is sucked into the generation part of the vacuum source through 14.

  In addition, one flow path through which a vacuum force is transmitted is formed in the inlet assembly so as to suck dust. Therefore, although the suction portion 14 has a strong suction input, the suction input decreases toward the both side portions (S). Therefore, although it works with good efficiency at the central portion (C) of the suction port 14 during cleaning, the cleaning efficiency of both side portions (S) of the suction port 14 is reduced, so that the surface to be cleaned having a large area is cleaned. Time is not preferred.

  Further, since the upper part of the suction port assembly is made of an opaque material so that the flow path formed in the suction port assembly cannot be confirmed when viewed from the outside, the dust even when the dust is caught in the suction port assembly. In order to confirm the position of the vacuum cleaner, the entire flow path of the vacuum cleaner must be confirmed.

  The present invention has been devised to solve the above-described problems. An object of the present invention is to provide an improved inlet assembly and an improved inlet assembly that can efficiently clean a surface to be cleaned over a wide area. It is to provide a vacuum cleaner.

  Another object of the present invention is to provide an improved inlet assembly and a vacuum cleaner provided with the inlet assembly which are improved so that the flow path can be confirmed from the outside.

It is preferable that the first flow path and the second flow path communicate with the respective mouths. Thereby, not only cleaning of a large area, but also the cleaning efficiency of the local surface to be cleaned where the first suction port and the second suction port face each other can be improved.

  Further, the upper housing forms an upper part of the first flow path and the second flow path, and is disposed on the flow path cover coupled to the lower housing, and on the upper portion of the flow path cover. It is preferable that an upper lid coupled to the housing is further included, and the first coupling portion formed on the edge of the flow path cover and the second coupling portion formed on the lower housing are kept airtight. By combining, loss of suction input can be prevented.

  Further, flow guide ribs are formed in the first flow path and the second flow path so as to be able to guide the sucked air in the direction of the vacuum source while preventing the swirl phenomenon. The suction input loss due to can be suppressed.

  An inlet assembly according to an embodiment of the present invention includes an upper housing and a lower housing coupled to the upper housing, and the upper housing includes an upper lid and a flow path cover. In the lower housing, two suction ports are formed at about 1/2 of the central portion and both side portions of the lower housing, and the suction ports are first and second formed by the lower housing and the flow path cover, respectively. It communicates with the second flow path. With such a structure, the suction input can be evenly distributed to the respective suction ports to improve the cleaning efficiency of the surface to be cleaned having a large area.

  Further, a first coupling portion is formed in the lower housing, and a second coupling portion is formed in the flow path cover so as to be coupled to and correspond to the first coupling portion. The first coupling part and the second coupling part may be implemented by a pair of steps, or may be implemented by ribs and rib grooves.

Accordingly, when the upper lid is coupled to the lower housing by a fastening member such as a screw, the pressure rib pressurizes the plunge portion of the flow path cover and is simultaneously accommodated in the guide rib, and the first coupling portion The second coupling unit is further coupled while maintaining confidentiality.

  In the upper lid, an incision is formed in a shape corresponding to the channel cover, and the channel cover is exposed to the outside through the incision. At this time, the channel cover is made of a transparent material, and the first channel and the second channel can be observed from the outside. It should be noted that when dust is caught, there is no need to confirm the entire flow path of the vacuum cleaner.

  According to the inlet assembly according to the present invention, the vacuum cleaner provided with the same, and the method of assembling the inlet assembly, the two passages are formed, thereby improving the cleaning efficiency of the side of the inlet assembly, A large area to be cleaned can be efficiently cleaned.

  By providing a transparent flow path cover, it is possible to visually check the flow of dust sucked into the suction port assembly, and when the dust is caught in the suction port assembly, the entire flow path of the vacuum cleaner is There is no hassle to check.

  Also, according to the assembling method of the suction port assembly, the vacuum cleaner equipped with the same, and the suction port assembly, the flow guide rib is provided on the flow path, thereby reducing the swirl of the sucked air and reducing the suction input. Can be suppressed.
