Description

  The present invention relates to a vacuum cleaner nozzle and a vacuum cleaner.

  Conventionally, a vacuum cleaner nozzle is detachably attached to the tip of the suction pipe. Various types of vacuum cleaner nozzles have been developed corresponding to the types of floors such as flooring, tatami mats, and carpets, and the purpose of gaps and futons.

  As such a cleaner nozzle, a cleaner nozzle for sucking dust adhering around legs of furniture with legs is also known (Japanese Patent Laid-Open No. 2010-82237). This vacuum cleaner nozzle has a pair of suction arms projecting into two branches, this suction arm sandwiches the lower end of a leg of furniture with legs, etc., and the suction port of the suction arm is the leg of furniture with legs. By approaching the lower end, dust or the like adhering to the lower end of the furniture leg is sucked.

  However, the vacuum cleaner nozzle has a pair of suction arms projecting from the bottom of the furniture leg to suck dust and the like attached to the rear side of the furniture leg. The suction pipe connected to the suction arm needs to go around the back of the furniture leg. In other words, in order to suck all dust and the like adhering to the periphery of the furniture leg, the user has to move the handle portion of the vacuum cleaner so that the suction pipe is moved to the vicinity of the rear side of the furniture leg. Therefore, when a space for cleaning around the furniture legs cannot be secured, it is necessary to replace the vacuum cleaner nozzle in order to suck all the dust around the furniture legs.

JP 2010-82237 A

  The present invention has been made in view of the circumstances as described above, and an object thereof is to provide a vacuum cleaner nozzle and a vacuum cleaner capable of efficiently sucking dust and the like attached to the periphery of legs of furniture and the like. It is.

  The vacuum cleaner nozzle of the present invention made to solve the above problems is a vacuum cleaner nozzle that is detachably attached to the tip of the suction pipe of the vacuum cleaner, and has a suction chamber provided with a suction port on the lower surface. The nozzle body includes an internal nozzle body, a connection pipe that is detachably attached to the suction pipe, and a communication pipe that communicates the suction chamber of the nozzle body with the connection pipe. It has a curved front wall and a rear wall facing the front wall and having a central portion protruding backward, and the communication pipe is slidably attached to the rear wall along the bending direction. It is characterized by that.

  In the vacuum cleaner nozzle, the curved front wall with the central portion protruding backward is brought into contact with the outer periphery of the leg of the furniture, etc., so that dust around the leg of the furniture, etc. Suction can be performed from the suction port on the lower surface. In addition, the connecting pipe that communicates with the suction pipe and the suction chamber of the vacuum cleaner is slidably attached along the curve direction on the rear wall that protrudes backward in the center. By doing so, it is possible to bring the portion of the curved front wall that is farthest from the sliding connecting tube into contact with the rear side of the leg of furniture or the like without largely moving the handle portion of the cleaner. Thereby, the dust etc. around legs, such as furniture, can be sucked in efficiently.

  Further, a through groove is formed in the rear wall along the bending direction, the communication pipe is slidably provided along the through groove of the rear wall, and the nozzle body is connected to the through groove. It is preferable to have an elastic member that closes a portion where no water is present. A through-groove is formed in the rear wall, and the nozzle body has an elastic member that closes the portion of the through-groove where the communication pipe does not exist, so that the intake air from the cleaner body for sucking dust and the like from the through-groove leaks. In addition, the communication pipe can slide along the rear wall of the nozzle body.

  Moreover, it is preferable that the said front wall is provided so that a deformation | transformation is possible so that the curvature radius of a curved shape may be changed. With this configuration, the angle of the curved shape of the front wall of the nozzle body can be adjusted to the shape of the legs of various furniture, etc., so that the front wall of the nozzle body can be brought into contact with the outer periphery of various shapes of furniture, etc. It can be easily and efficiently sucks dust around the legs of furniture and the like.

  Furthermore, it is preferable that the front wall is provided so as to be deformable into a flat plate shape. By deforming the front wall of the nozzle body into a flat plate shape, the nozzle body can be used as an ordinary cleaner nozzle without being limited to the use around a leg of furniture or the like.

  Moreover, in the said nozzle for vacuum cleaners, it is preferable that the said front wall is provided so that elastic deformation is possible. Since the front wall of the nozzle body is elastically deformed, the front wall of the nozzle body can be brought into contact with the outer periphery of a leg of furniture or the like without a gap. Thereby, the dust etc. around legs, such as furniture, can be certainly sucked.

  Furthermore, the vacuum cleaner of this invention is equipped with the above-mentioned nozzle for vacuum cleaners. In the cleaner, the curved front wall of the cleaner nozzle of the cleaner is brought into contact with the outer periphery of the leg of the furniture, etc. Can be sucked from the suction port. In addition, the connecting pipe that communicates with the suction pipe and the suction chamber of the vacuum cleaner is slidably attached along the curve direction on the rear wall that protrudes backward in the center. By doing so, it is possible to bring the portion of the curved front wall that is farthest from the sliding connecting tube into contact with the rear side of the leg of furniture or the like without largely moving the handle portion of the cleaner. Thereby, the dust etc. around legs, such as furniture, can be sucked in efficiently.

  In the above description, “the center part protrudes backward” means that the center part in plan view protrudes to the rear wall side with respect to the front wall side.

  As described above, the vacuum cleaner nozzle and the vacuum cleaner of the present invention can efficiently suck in dust and the like attached around the legs of furniture and the like.

<Nozzle 2 for vacuum cleaner>
As shown in FIG. 2, the cleaner nozzle 2 includes a nozzle body 11, a connecting pipe 12, and a connecting pipe 13.

  The nozzle body 11 has a curved front wall 11b whose central portion protrudes rearward, and a rear wall 11a that faces this front wall and whose central portion protrudes rearward. Both ends of the rear wall 11a are in contact with both ends of the front wall 11b, and the nozzle body 11 is formed in a substantially crescent shape in plan view.

  The nozzle body 11 has a through groove 11c formed in the rear wall 11a.

  The through-groove 11c is formed in a belt-like shape at the central portion in the longitudinal direction of the rear wall 11a and at the portion connecting the intermediate portions of both end portions and the central portion of the rear wall 11a in the lateral direction.

  Further, the nozzle body 11 has a suction chamber having a suction port on the lower surface of the nozzle body 11 (not shown). The shape of the suction port is not particularly limited, and may be formed in the same shape as the substantially crescent shape of the nozzle body 11 or may be formed in a rectangular shape. The suction chamber is defined by the rear wall 11 a and the front wall 11 b and is formed inside the nozzle body 11. Accordingly, the through wall 11 a of the nozzle body 11 is formed on the rear wall 11 a side of the suction chamber, and the suction chamber communicates with the connecting pipe 13 through the through groove 11 c of the nozzle body 11.

  The nozzle body 11 has a lever 11 d on the upper surface of the nozzle body 11. The lever 11d is formed to move between the rear wall 11a side and the front wall 11b side of the nozzle body, and can be positioned stepwise.

  The lever 11 d is formed so as to interlock with the front wall 11 b of the nozzle body 11. Thereby, the bending angle of the curved shape of the front wall 11b of the nozzle body 11 can be adjusted, and the curvature radius of the curved shape of the front wall 11b of the nozzle body 11 can be changed. Specifically, the lever 11d and the front wall 11b of the nozzle body 11 are not particularly limited, but are connected inside the nozzle body 11 via a locking tool such as a wire or a spring, for example. Thereby, by moving the lever 11d, the front wall 11b of the nozzle body 11 is interlocked via the locking tool, and the bending angle of the curved shape of the front wall 11b is changed.

  Further, the front wall 11b of the nozzle body 11 is formed of an elastic member. Specifically, although not particularly limited, elastic rubber such as urethane rubber, styrene / butadiene rubber, and fluoro rubber can be used.

  When the lever 11d is positioned on the rear wall 11a side of the nozzle body 11 as shown in FIG. 2, the elastic member is pulled toward the rear wall 11a side of the nozzle body 11 by the lever 11d that is connected via a locking tool. . Since the elastic member portions (both end portions of the front wall of the nozzle body 11) that are in contact with the rear wall 11a of the nozzle body 11 are supported by both end portions of the rear wall 11a of the nozzle body 11, the front wall 11b of the nozzle body 11 is used. Has a curved shape in which the central part protrudes backward.

  When the lever 11d is moved from the rear wall 11a side of the nozzle body 11 to the front wall side 11b side of the nozzle body 11, the elastic member portion of the front wall 11b of the nozzle body 11 extends. Then, when the lever 11 is positioned most on the front wall 11b side of the nozzle body 11, the shape of the elastic member portion of the front wall 11b of the nozzle body 11 becomes substantially half-moon shape as shown in FIG.

  That is, in a state where the lever 11d is positioned on the rear wall 11a side of the nozzle body 11, the front wall 11b of the nozzle body 11 is positioned closest to the rear wall 11a side of the nozzle body 11 (see FIG. 2). Then, by moving the lever 11d toward the front wall 11b of the nozzle body 11, the bending angle of the curved shape of the front wall 11b of the nozzle body 11 becomes shallow, and the curvature radius of the curved shape changes. Furthermore, when the lever 11d is positioned most on the front wall 11b side of the nozzle body 11, the front wall 11b of the nozzle body 11 becomes a flat plate shape (see FIG. 3). The deformed shape of the front wall 11b of the nozzle body 11 is not particularly limited, but the shape can be maintained by being supported by the locking tool.

  Further, the shape of the suction port of the suction chamber can be deformed in accordance with the change in the curvature radius of the curved shape of the front wall 11b of the nozzle body 11. For example, a configuration in which the area of the suction port of the suction chamber is expanded according to the shape of the nozzle body 11 can be employed. That is, in the state where the front wall 11b of the nozzle body 11 has a flat plate shape, the suction port of the suction chamber can be formed in a substantially half-moon shape in accordance with the shape of the front wall.

  The connecting pipe 12 is inserted into and communicated with the connecting pipe 13. The connecting pipe 12 is connected to the extension pipe 6 so as to be detachable, and is connected to the cleaner body 3.

  As shown in FIG. 4, the connecting pipe 13 is connected to the through groove 11 c in the rear wall 11 a of the nozzle body 11 and communicated with the suction chamber. Thereby, dust or the like sucked from the suction port on the lower surface of the nozzle body 11 is sent to the dust collection chamber of the cleaner body 3 through the connecting pipe 13.

  The connecting tube 13 has a convex locking portion 13a at the end of the nozzle body 11 on the side connected to the through groove 11c (see FIG. 5A). The convex locking portion 13a is locked to the inside of the nozzle body 11 of the through groove 11c of the nozzle body 11, so that the connecting pipe 13 is prevented from being detached from the through groove 11c.

  The connecting pipe 13 is slidably attached along the rear wall 11 a of the nozzle body 11. The connecting pipe 13 is connected to one part of the through groove 11 c of the nozzle body 11, and the connecting pipe 13 slides along the through groove 11 c of the nozzle body 11 when the connecting part slides.

  The through groove 11c of the nozzle body 11 is formed so that the periphery of the through groove 11c is formed by an elastic member 11e (see FIG. 5B) and sandwiches the connecting pipe 13 (see FIG. 5A). The elastic member 11e is not particularly limited, and elastic rubber such as urethane rubber, styrene / butadiene rubber, and fluorine rubber can be used. Thereby, the connecting pipe 13 can be fixed to a desired location of the through groove 11c of the nozzle body 11, and the through groove 11c of the nozzle body 11 can be slid by shifting the connecting pipe 13 left and right. .

  In addition, slide plates that slide laterally toward the inside of the nozzle body 11 of the through groove 11c of the nozzle body 11 can be formed on the left and right sides of the connecting pipe 13 (not shown). These slide plates are joined to the connecting tube 13, and when the connecting tube 13 slides along the through groove 11 c of the nozzle body 11, the slide plate also fits the connecting tube 13 and the through groove of the nozzle body 11. Slide to cover the gap 11c. When the slide plate is joined to the connecting pipe 13 and slides in accordance with the sliding of the connecting pipe 13, intake air from the cleaner body 3 for sucking dust and the like leaks from the through groove 11 c of the nozzle body 11. Can be prevented.

  It should be noted that in the joint portion between the slide plate of the through groove 11c of the nozzle body 11 and the connecting pipe 13, the gap may be shielded by a seal or the like in order to prevent the intake air from leaking from the joint portion.

  As described above, the through-groove 11c of the nozzle body 11 and the connecting pipe 13 are connected, so that the connecting pipe 13 can slide on the rear wall 11a of the nozzle body 11. Accordingly, as shown in FIG. 6A, the connecting pipe 13 is moved from the position of the central portion in the plan view of the rear wall 11a of the nozzle body 11, and as shown in FIG. By moving the connecting tube 13 to one end side from the center of the rear wall 11a of the main body 11 in plan view, it is far from the location where the connecting tube 3 is located on the curved front wall 11b of the nozzle body 11. One end can be located at a location far from the connecting tube 13.

<Advantages>

It can be made to contact. Thereby, dust around legs of furniture or the like can be sucked from the suction port on the lower surface of the nozzle body 11. Further, a connecting pipe 13 communicating with the suction pipe of the cleaning device is connected to a through groove 11c formed in the rear wall 11a of the nozzle body 11 and communicating with the suction chamber, and is formed in a band shape in the lateral direction of the rear wall 11a of the nozzle body 11. In order to slide through the formed through-groove 11c, the portion of the front wall 11b of the curved shape of the nozzle body 11 that is farthest from the connecting tube 13 does not move the handle tube 5 part greatly. It becomes easy to contact the rear side. Thereby, the dust etc. around legs, such as furniture, can be sucked in efficiently.

  Further, in the cleaner nozzle 2 of the cleaner 1, the angle of the curved shape of the front wall 11 b of the nozzle body 11 can be changed by operating the lever 11 d of the nozzle body 11. The angle of the curved shape of the front wall 11b of the nozzle body 11 can be adjusted in accordance with the shape of the leg of a piece of furniture or the like. Thereby, even in the shape of legs of various furniture and the like, dust and the like around the legs can be efficiently sucked.

  Furthermore, by positioning the lever 11d of the nozzle body 11 closest to the front wall 11b side of the nozzle body 11, the front wall 11b of the nozzle body 11 has a flat plate shape, so that it becomes the shape of a normal vacuum cleaner nozzle, The vacuum cleaner nozzle 2 can be used as a normal vacuum cleaner nozzle.

  Further, in the cleaner nozzle 2 of the cleaner 1, the front wall 11 b of the nozzle body 11 is formed of an elastic member, so that the front wall 11 b of the nozzle body 11 is spaced from the outer periphery of a leg such as furniture. Can be brought into contact with each other. For this reason, the dust etc. around legs, such as furniture, can be sucked in reliably.
