Description

  The present invention equips a floor nozzle with a small nozzle, enables a small nozzle corresponding to a narrow place difficult to clean with the floor nozzle to be detached from the floor nozzle, and freely switches between the floor nozzle and the small nozzle for cleaning. The present invention relates to a vacuum cleaner suction tool that can be used and a vacuum cleaner using the same.

  FIG. 11 shows an example of a floor-moving vacuum cleaner, in which an extension tube 2 having a floor nozzle 50 detachably mounted at the tip is connected to a handle handle 4, and a hose 6 extending from the handle handle 4 is provided. The hose joint 5 is connected to the cleaner body 7. When cleaning with such a vacuum cleaner, the floor surface can be efficiently cleaned by the wide floor nozzle 50, but the floor nozzle 50 is used for steps, etc., where the floor area is smaller than the plane area of the floor nozzle 50. I can't. Generally, the vacuum cleaner is provided with an accessory nozzle such as a clearance nozzle or a brush nozzle. Remove the extension tube 2 from the handle 4 at hand, attach any accessory nozzle to the handle 4, and use the nozzle at the floor nozzle 50. You will have to clean places that cannot be done.

  However, the replacement work between the floor nozzle 50 and the attached nozzle is troublesome, and the detached extension pipe 2 and the floor nozzle 50 connected to the extension nozzle 2 cannot be leaned against the wall surface because the floor nozzle 50 has the traveling roller, and the floor nozzle 50 is not placed. Often, troublesome situations occur. If the floor nozzle 50 can be easily converted into a small nozzle adapted to a narrow place, the cleaning operation using the vacuum cleaner becomes easier. As a conventional technique for realizing this, a vacuum cleaner disclosed in Japanese Patent Application Laid-Open No. 2001-314358 is known.

This vacuum cleaner (vacuum cleaner) has a feature in a suction tool, and the suction tool has a vertical rotation and a rotation in the tip end portion of the extension tube 213 as shown in FIG. A hollow brush nozzle 250 is attached via a ball joint 240 that enables the brush nozzle 250 to be attached to and detached from an opening 211 a communicating with the suction port of the floor nozzle 210. When the brush nozzle 250 is attached to the floor nozzle 210, the floor nozzle 210 is attached to the tip of the extension pipe 213, so that an air flow passage from the hollow brush nozzle 250 to the floor nozzle 210 is formed. In addition, the floor surface can be cleaned using the floor nozzle 210, and the brush nozzle 250 can be detached from the floor nozzle 210 by pressing down the pressing portion 320 with a foot as needed. With this configuration, the floor nozzle 210 and the brush nozzle 250 can be switched without bending, and the convenience can be easily switched from cleaning the floor surface to cleaning a narrow place such as a staircase. .

  However, in the vacuum cleaner according to the related art, the height when the floor nozzle 210 is used becomes large, and the floor nozzle 210 cannot enter a space having a small height. There are issues.

  In addition, since the ball joint 240 is in the vertical direction of the floor nozzle 210 and the extension pipe 213 is connected to the ball joint 240 in an obliquely upward direction and is operated from the hand, when the floor nozzle 210 changes direction, Even if the operation of rotating the extension tube 213 occurs, the floor nozzle 210 hardly moves in the direction in which the direction changes, and there is a problem that cleaning using the floor nozzle 210 cannot be performed smoothly.

  Further, since the brush nozzle 250 is connected via the ball joint 240 that rotates in the rotation direction and the vertical direction, when the brush nozzle 250 is detached from the floor nozzle 210 and the brush nozzle 250 is used for cleaning, the brush nozzle 250 is used. There is a problem that the angle of 250 is not stable and the cleaning operation is difficult.

This embodiment shows a floor moving type vacuum cleaner 1 as shown in FIG. 1 and a suction tool 3 serving as a dust suction port thereof. In this vacuum cleaner 1, an extension tube 2 having a suction tool 3 detachably attached to a tip thereof is connected to a hand handle (hand operation tube) 4, and a hose 6 extending from the hand handle 4 is connected to a hose cleaner 5 by a hose joint 5. It is connected to the main body 7.

  As shown in FIGS. 2A and 2B, the suction tool 3 is connected to a connecting pipe (connecting section) 9 for connecting to the extension pipe 2 via a rotary connecting section (rotating connecting means) 8. The small nozzle 10 to which the suction head 40 is connected is detachably mounted on the floor nozzle 11. When the small nozzle 10 is attached to and detached from the floor nozzle 11, the gripping state of the holder 12 that grips the small nozzle 10 is released by depressing the operation lever 13 provided on the floor nozzle 11, and the small nozzle 10 is detached from the floor nozzle 11. The small nozzle 10 is mounted on the floor nozzle 11 by placing the small nozzle 10 in the holder 12 and lightly pressing the small nozzle 10 by using the small nozzle 10. Thus, the floor can be efficiently cleaned.

  As shown in FIGS. 3 (a), 3 (b), and 3 (c), the small nozzle 10 has an arcuate lower surface which is a surface in the mounting direction to the floor nozzle 11, and is raised at the top of the arc in the arc axis direction. A blanket (raised body) 14 is adhered, a lower surface air inlet 15 is opened on both sides thereof, and the raised fabric 14 is also adhered to each side. Further, at the tip end side, a tip suction port 16 communicating with a suction port 23 of the floor nozzle 11 described later is opened, and in a state where the small nozzle 10 is separated from the floor nozzle 11, as shown in FIG. The opening 16 is closed by a spring-biased lid 18 except for a part on the lower surface side. Reference numeral 17 denotes a pair of right and left power supply contacts for supplying power to a motor 21 for rotating and driving a rotary brush provided on the floor nozzle 11, which will be described later. The lead wire from the cleaner body 7 is connected to the hose 6, When the small nozzle 10 is connected to the extension pipe 2 by the connection pipe 9, the power supply portion 19 provided on the connection pipe 9 is connected to the extension pipe 2 through the handle 4 and the extension pipe 2. Are connected electrically to the power supply contact 17 through the inside of the small nozzle 10 from the power supply section 19.

  The raised cloth 14 is made by densely raising fine hairs on the sheet surface. The both sides of the lower intake port 15 are closed to improve the ability of sucking dust from the lower intake port 15. Dust in the concave portion is scraped out, and dust on the cleaning surface is guided to the lower surface intake port 15 to exert an effect of wiping the cleaning surface, and also has a function of a bumper that does not damage furniture and the cleaning surface. The brushed cloth 14 is the most desirable for applying to the small nozzle 10, but a brush, felt or the like having the same shape can also be used.

  In the configuration of the present embodiment, the lower surface suction ports 15 of the small nozzles 10 are provided in two rows, but are provided in one row at the apex of the arc, and the raised cloth 14 is provided on both sides thereof. It can also be configured.

  As shown in FIG. 5, the floor nozzle 11 is configured as a so-called power nozzle, and rotates a rotating brush 20 having a brush and a rubber blade attached to a rotating shaft by a motor 21 to remove dust from a carpet or the like. It has the function of scraping. The power supply to the motor 21 is performed by mounting the small nozzle 10 so that the pair of power supply contacts 17 disposed on the small nozzle 10 slidably contact the pair of power receiving contacts 22 disposed on the floor nozzle 11. This is done by:

  The floor nozzle 11 is provided with a wide suction portion 24 having a horizontally long suction port 23 accommodating the rotary brush 20 and a running portion 25 projecting rearward from a central portion thereof. As shown in FIG. 6, a small nozzle storage recess 26 is formed on the upper surface side from the rear end of the traveling portion 25 to the suction portion 24. A communication port 27 communicating with the suction port 23 is opened at a front side inside the small nozzle storage recess 26. When the small nozzle 10 is mounted in the small nozzle storage recess 26, a tip suction port formed in the small nozzle 10 is formed. The lid 18 is opened, and the communication between the communication port 27 and the front-end intake port 16 communicates with each other to form an air flow path to the cleaner body 7.

  FIG. 7 is a cross-sectional view showing a state in which the small nozzle 10 is mounted on the floor nozzle 11. When the small nozzle 10 is mounted on the floor nozzle 11, the small nozzle 10 projects from the front side to the rear side in the small nozzle storage recess 26. The opening / closing operation rib (tip suction port opening / closing means) 28 rotates the lid 18, which partially closes the tip suction port 16 of the small nozzle 10 by the spring bias, and opposes the spring bias as shown in the figure. Then, the lid 18 is opened to make the front-end intake port 16 fully open, and an air flow path from the intake port 23 to the connecting pipe 9 is formed. In addition, since the lower surface suction port 15 of the small nozzle 10 is closed by the bottom surface of the small nozzle storage recess 26, when the small nozzle 10 is mounted on the floor nozzle 11, only suction from the suction port 23 is performed, and the floor nozzle 11 Dust absorption capacity is not impaired.

  As shown in FIG. 6, the small nozzle storage recess 26 formed in the floor nozzle 11 is formed at a depth substantially equal to the height dimension of the small nozzle 10, and when the small nozzle 10 is stored therein, As shown in FIG. 2 (b) and FIG. 7, the flat nozzle 11 is configured such that the floor nozzle 11 can be inserted into a space vacated beneath the furniture, with only a small nozzle 10 coming out from the upper surface of the floor nozzle 11. can do. The height of the floor nozzle 11 can also be reduced by arranging small turning wheels 36 on both sides of the small nozzle housing recess 26 as shown in FIG.

  When the operation lever 13 provided on the floor nozzle 11 is pushed down (stepped on with a foot), the small nozzle 10 can be detached from the floor nozzle 11. As shown in FIG. 4, the lid 18 provided at the distal intake port 16 is not pressed by the opening / closing operation rib (tip intake port opening / closing means) 28. The intake port 16 is closed. At this time, by setting the vertical dimension of the lid 18 to be smaller than the opening height of the distal intake port 16, a state in which the distal intake port 16 is partially closed in a state where the lower part is opened can be obtained. Further, since the lower intake port 15 is in an open state, an air flow path from the lower intake port 16 and the plurality of lower intake ports 15 to the connecting pipe 9 is formed, and the dust collecting function by the small nozzle 10 is obtained.

  Next, a structure for attaching and detaching the small nozzle 10 to and from the floor nozzle 11 will be described with reference to FIGS.

  8 and 9, a holding tool (small nozzle attaching / detaching means) 12 is provided in a small nozzle storage recess 26 formed in the floor nozzle 11 so as to follow the cross-sectional shape thereof. The holding tool 12 is connected to a pair of left and right at a center hinge portion, and can be switched between a released state shown in FIG. 8 and a gripped state shown in FIG. 9. The operation is performed by pushing down the operation lever 13. By pressing the small nozzle 10 into the holder 12 in the released state shown in FIG. 8, that is, the detached state of the small nozzle 10, the holding state shown in FIG.

  In the detached state shown in FIG. 8, the holding tool 12 is in a state where the holding tool 12 is expanded left and right from the center hinge portion, and when the small nozzle 10 is pushed into the holding tool 12, a pressing member disposed at the center of the hinge portion is pressed. 9 is pressed and lowered while the raised cloth 14 at the top of the arc side surface of the small nozzle 10 is divided and arranged front and rear (see FIG. 3), so that the holder 12 descends to the bottom side of the small nozzle storage recess 26, and FIG. As shown in the figure, the small nozzle 10 is gripped so as to wrap around the suction head 40 portion. With the lowering of the pressing member 29, the driving member 32 connected thereto pushes down one end of the rod 30 pivotally supported by the support member 31, so that the operating lever 13 provided at the other end of the rod 30 is shown in FIG. Ascending position. The pressing member 29, the rod 30, the supporting member 31, and the driving member 32 together with the holder 12 constitute a small nozzle attaching / detaching means 38.

  In order to further ensure the mounting state of the small nozzle 10 by the holder 12, locking pins 33 urged outward are provided on both side surfaces of the small nozzle 10 as shown in FIG. When the holding recess 12 is formed in the holding tool 12, when the small nozzle 10 is pushed into the holding tool 12, the locking pin 33 is fitted into the holding recess 34, and the small nozzle is stably mounted on the floor nozzle 11. The state is obtained. The holder 12 is provided with a raised cloth storage recess 35 for receiving the raised cloth 14 provided in the small nozzle 10, and the raised cloth 14 is crushed when the small nozzle 10 is mounted, and its function is performed. We prevent being damaged.

  In order to release the small nozzle 10 from the mounting state of the small nozzle 10 with respect to the floor nozzle 11 shown in FIG. 9, when the operation lever 13 at the raised position is depressed, the rod 30 rotates about the support member 31 as a fulcrum, and the driving member Since the hinge portion of the holder 12 is pushed up by 32, the small nozzle 10 is pushed up by the pressing member 29 at the same time when the holder 12 is opened, and the small nozzle 10 can be detached from the floor nozzle 11.

  As described above, the small nozzle 10 is provided with the rotary connecting portion 8 that rotatably connects the suction head 40 and the connecting pipe 9 in the up-down direction and the left-right direction. As shown in the drawing, when the small nozzle 10 is mounted on the floor nozzle 11, as shown in FIG. 1, the rotation connecting portion corresponds to the raising and lowering of the hand handle 4 connected to the connecting pipe 9 via the extension pipe 2. Reference numeral 8 denotes a movement for rotating the hand handle 4 in a vertical direction, that is, a movement for rotating the hand handle 4 in the course direction when a handle operation for changing the course direction of the floor nozzle 11 to the left or right direction is performed. When the rotation of the shaft is applied to the rotation connecting portion 8, the movement of the floor nozzle 11 in the rotation direction of the shaft is caused by the rotation connecting portion 8 behind the floor nozzle 11. Works, and the course of floor nozzle 11 changes smoothly. It is.

  In the state where the small nozzle 10 is detached from the floor nozzle 11, it becomes difficult to handle the small nozzle 10 in the rotation direction. Therefore, a rotation direction rotation locking means for locking the rotation connection portion 8 in the rotation direction is provided. be able to. The rotation direction rotation locking means includes a spring-biased locking member. When the small nozzle 10 is mounted on the floor nozzle 11, the spring release biasing means provided on the floor nozzle 11 side biases the spring. When the locking member is released from the locked state of rotation in the rotation direction against the rotation of the floor nozzle, the rotation direction rotation locking means does not function when the small nozzle 10 is mounted on the floor nozzle 11. When the small nozzle 10 is detached from the floor nozzle 11, the rotation direction rotation locking means functions to lock the rotation of the small nozzle 10 in the rotation direction. it can.

  When the small-sized nozzle 10 is attached to the floor nozzle 11, the vacuum cleaner 1 using the suction tool 3 having the above-described configuration cleans the floor with the wide floor nozzle 11 in the same manner as a general vacuum cleaner. When the operation lever 13 is stepped on as needed to clean a narrow place or a stair where the floor nozzle 11 cannot enter, the small nozzle 10 can be detached from the floor nozzle 11 without bending down. Since the cleaning using the small nozzle 10 can be performed, the troublesome work of replacing the tip nozzle can be eliminated. Further, since the floor nozzle 11 from which the small nozzle 10 has been detached is on the floor surface, if the small nozzle 10 is arbitrarily pushed into the floor nozzle 11, it can be immediately changed to floor cleaning.

  When the small nozzle 10 is used in a state where it is detached from the floor nozzle 11, the surface on which the lower surface air inlet 15 is formed is formed in an arc shape, so that the small nozzle 10 is free with respect to the cleaning surface as schematically illustrated in FIG. In particular, as shown in FIG. 10 (b), the intake of the lower surface intake port 15 acts on the corner of the wall or the rising edge of the furniture to collect and remove dust in the corner as shown in FIG. it can. Further, as described above, since the front end suction port 16 of the small nozzle 10 is closed by the lid 18 while leaving the lower side surface when detached from the floor nozzle 11, the opening area of the front end suction port 16 is reduced. Increases, and the nozzle is opened on the side close to the cleaning surface, so that the small nozzle 10 can also obtain a dust collecting effect from the tip side, and can perform cleaning over a wider area. The front intake port 16 may be configured so that the entire opening area is closed by the lid 18 to increase the intake capacity from the lower intake port 15.

  When the small nozzle 10 is mounted on the floor nozzle 11 by operating the handle 4 at hand, there is a small turning wheel 36 on the rear side of the floor nozzle 11, and the floor nozzle 11 stands up or moves forward with the small turning wheel 36 as a fulcrum. A small turning wheel 36 is provided behind the turning fulcrum of the turning connecting portion 8 provided on the small nozzle 10 so as not to run.

  Further, the suction device 3 having the configuration of the present embodiment can be applied to an electric vacuum cleaner called a hand cleaner in which a suction device is attached to a small vacuum cleaner main body with a short handle with a short handle. Function can be improved.

  As described above, according to the present invention, it is possible to use a floor nozzle and a small nozzle as needed to clean a wide area with one suction tool, and to reduce the height of the floor nozzle equipped with the small nozzle. The floor nozzle can be inserted into a place with a small height for cleaning.
