【Example】
Example 1
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
[0011]
This embodiment shows the floor moving type electric vacuum cleaner 1 as shown in FIG. 1 and the suction tool 3 as the dust suction port. In this vacuum cleaner 1, an extension tube 2 having a suction tool 3 detachably attached to the tip is connected to a hand handle (hand control tube) 4, and a hose 6 extending from the hand handle 4 is cleaned by a hose joint 5. It is connected to the machine body 7.
[0012]
As shown in FIGS. 2 (a) and 2 (b), the suction tool 3 includes a floor nozzle 11 and a small nozzle 10 that is detachably attached thereto, and the small nozzle 10 is connected to the extension pipe 2. A connecting pipe 9 serving as a connecting part, and a rotating connecting part (rotating connecting means) 8 whose rear part is connected to the connecting pipe 9 so as to be able to tilt up and down and whose front part is rotatably connected to the intake head 40. Yes.
[0013]
The small nozzle 10 is attached to and detached from the floor nozzle 11 by depressing the operation lever 13 provided on the floor nozzle 11 so that the holding state of the holder 12 that holds the small nozzle 10 is released and the small nozzle 10 is detached from the floor nozzle 11. The small nozzle 10 can be cleaned using a small nozzle 10, and the small nozzle 10 is mounted on the floor nozzle 11 by placing the small nozzle 10 in the holder 12 and pressing lightly, and the floor nozzle 11 is used. The floor can be cleaned efficiently.
[0014]
As shown in FIG. 3, the floor nozzle 11 is configured as a so-called power nozzle, and a rotary brush 20 having a brush (not shown) and a rubber blade (not shown) attached to a rotary shaft 20a is used as a motor. 21 has a function of being driven to rotate and scraping dust from a carpet or the like.
[0015]
Next, the attachment / detachment structure of the small nozzle 10 with respect to the floor nozzle 11 is demonstrated with reference to FIG.4 and FIG.5.
[0016]
4 and 5, a holder (small nozzle attaching / detaching means) 12 is disposed in the small nozzle housing 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 the central hinge portion, and can be switched between a release state shown in FIG. 4 and a gripping state shown in FIG. 5, and the operation is performed by depressing the operation lever 13. The released state shown in FIG. 4, that is, the small nozzle 10 is detached, and the small nozzle 10 is pushed into the holder 12, so that the holding state shown in FIG. 5, that is, the small nozzle 10 is attached.
[0017]
In the disengaged state shown in FIG. 4, the holding tool 12 is in a state where it is unfolded from the central hinge part to the left and right. Since 29 is pressed and lowered, the holding tool 12 descends to the bottom surface side of the small nozzle housing recess 26 and grips the intake head 40 portion of the small nozzle 10 as shown in FIG. As the pressing member 29 is lowered, the drive member 32 connected thereto pushes down one end of the rod 30 pivotally supported by the support member 31, so that the operation lever 13 provided at the other end of the rod 30 is shown in FIG. So that it goes up. The pressing member 29, the rod 30, the support member 31, and the driving member 32 constitute a small nozzle attaching / detaching means 38 together with the holder 12. The operation lever 13 is always urged upward by an elastic material (spring) 31a around the rotation fulcrum of the support member 31 and the drive member 32.
[0018]
In order to make the mounting state of the small nozzle 10 by the holder 12 more reliable, as shown in the figure, locking pins 33 that are urged outward are provided on both side surfaces of the small nozzle 10, and correspondingly, 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 fits into the locking recess 34, and the small nozzle is stably attached to the floor nozzle 11. A state is obtained. The holder 12 is formed with a raised cloth storage recess 35 for accommodating the raised cloth 14 provided in the small nozzle 10, and the raised cloth 14 is crushed and deformed in a state where the small nozzle 10 is attached, The function is prevented from being impaired.
[0019]
To release the small nozzle 10 from the mounted state of the small nozzle 10 with respect to the floor nozzle 11 shown in FIG. 5, when the operating lever 13 in the raised position is pushed down, the rod 30 rotates about the support member 31 as a fulcrum. 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 as the holder 12 is opened, and the small nozzle 10 can be detached from the floor nozzle 11.
[0020]
As described above, the small nozzle 10 is provided with the rotation connecting portion 8 that rotatably connects the intake head 40 and the connecting pipe 9 in the vertical and horizontal directions, as shown in FIG. When the small nozzle 10 is mounted on the floor nozzle 11, the connecting tube 9 tilts up and down in response to the raising and lowering of the hand handle 4 connected to the connecting tube 9 via the extension tube 2 as shown in FIG. To do. Further, when the hand handle 4 is rotated, that is, when the handle operation for changing the course direction of the floor nozzle 11 to the left or right direction is performed, the hand handle 4 is naturally moved in the course direction. Therefore, when rotation of the shaft is applied to the rotation connecting portion 8, the rotation connecting portion 8 is provided on the rear side of the floor nozzle 11, so that the movement of the floor nozzle 11 rotating in the rotation direction of the shaft works smoothly. The course of the floor nozzle 11 is changed.
[0021]
In the state where the small nozzle 10 is detached from the floor nozzle 11, it becomes difficult to handle when the small nozzle 10 moves in the rotation direction. Therefore, the rotation direction rotation locking means for locking the movement of the rotation connecting portion 8 in the rotation direction (see FIG. (Not shown). The rotation direction rotation locking means is provided with a spring-biased locking member (not shown). When the small nozzle 10 is mounted on the floor nozzle 11, the locking release provided on the floor nozzle 11 side is released. If the locking member is removed from the locked state of rotational rotation by means (not shown) against spring bias, the rotational nozzle rotates in the state where the small nozzle 10 is mounted on the floor nozzle 11. Since the locking means does not function, the floor nozzle 11 can freely rotate in the vertical and rotational directions. When the small nozzle 10 is detached from the floor nozzle 11, the rotational direction rotation locking means functions and the small nozzle 10 The rotation in the rotation direction can be locked.
[0022]
In the vacuum cleaner 1 using the suction tool 3 having the above-described configuration, when the small nozzle 10 is mounted on the floor nozzle 11, the wide floor nozzle 11 efficiently cleans the floor surface like a general vacuum cleaner. The small nozzle 10 can be detached from the floor nozzle 11 without bending the waist if the operation lever 13 is stepped on as required to clean a narrow place or stairs where the floor nozzle 11 does not enter. Since the cleaning using the small nozzle 10 can be performed, the troublesome work of changing the tip nozzle is eliminated. Further, since the floor nozzle 11 from which the small nozzle 10 is 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.
[0023]
In the above embodiment, the floor moving type vacuum cleaner is taken as an example, but this embodiment is applied to a vacuum cleaner called a hand cleaner in which a suction tool is attached to a small vacuum cleaner body with a hand handle by a short pipe line. The suction tool 3 having the structure can be applied, and the function as a hand cleaner can be improved.
[0024]
As shown in FIG. 6, the small nozzle 10 has two rotors 15 a and 15 b each having a cut fiber-like raised cloth made of a spun cloth of ultrafine fibers spirally wound, and has a suction opening for sucking dust. It faces the chamber 7 and is rotatably provided. As shown in FIG. 7, the fibers of the raised cloth wound around the outer circumferences of the rotors 15a and 15b are lying in one direction substantially perpendicular to the rotation shaft 15c (the direction opposite to the rotation direction). And it is wound spirally. Further, as shown in FIG. 8, the tip of the small nozzle 10 is provided with an air volume adjusting valve 9 which is an air volume adjusting portion so that one end is pivotally supported and the opening 17a can be opened and closed, and a spring 18 which is an elastic body. Is held by.
[0025]
In this embodiment, two rotors are provided. However, even if one or more rotors are provided, the wiping and sweeping effects described below can be sufficiently exhibited.
[0026]
The operation in the above configuration is as follows.
[0027]
When the cleaner body 7 is operated, an electric blower (not shown) built in the cleaner body 7 is activated, and the suction air a flows toward the suction chamber 16. Thereafter, the suction air a collides with the raised cloths of the rotors 15a and 15b, thereby rotating the rotors 15a and 15b by wind pressure. In this embodiment, the air is rotated by the suction air a flowing into the suction chamber 16 through the gap between the surface to be cleaned and the lower surface of the small nozzle 10, and is further opened on the side surface of the suction tool 3. It is good also as a structure which makes suction air a flow in into the said suction chamber 16 from the said opening, and rotates the said rotor 15a, 15b with the suction air flowed in in the said suction chamber 16. FIG.
[0028]
Further, the fibers of the raised cloth wound around the outer circumferences of the rotors 15a and 15b are laid down in a direction substantially perpendicular to the rotation shaft 15c (the direction opposite to the rotation direction), and the suction air a is laid down. Since the impregnated fibers collide with the rotors 15a and 15b from the front end side of the raised cloth, the lying fibers become windshields and a strong rotational force is obtained. The suction air a collides with the rotors 15a and 15b from the tip side of the lying raised cloth, but if the suction air a does not flow in from the fiber root side of the raised cloth, the rotational force is obtained. However, it is desirable that the suction air a flows in the range of about 45 ° in the left-right direction with respect to the tip of the raised cloth.
[0029]
Further, the air volume adjusting valve 17 is pushed by the suction air from the opening 17a, the front of the suction chamber 16 is opened, and is stationary at a position where the spring 18 and the force can be balanced. Accordingly, when the air volume is large, the suction chamber 16 is brought close to opening, noise is prevented by lowering the rotation speed of the rotors 15a and 15b, or when the air volume is small, the suction chamber 16 is made close to the airtight and the rotor 15a. By increasing the rotational speed of 15b, improvement in wiping, sweeping and polishing performance can be realized. Further, when the small nozzle 10 is attached to the floor nozzle 11, the air volume control valve 17 opens fully and forms an air flow path.
[0030]
As described above, in this embodiment, since the rotors 15a and 15b wound with a brushed cloth on the outer periphery can be rotated only by the air flow, a mechanical drive source such as a motor is not required, and is small and lightweight. It is possible to provide a suction tool with high wiping, sweeping and polishing performance at a low price.
[0031]
In addition, since air is directly applied to the fibers of the raised cloth and rotated, the structure of the raised cloth alone is not used, and no other mechanical parts are used. Therefore, it is possible to provide a suction device with a simple structure, high reliability, and low cost. it can.
[0032]
In addition, by raising the fibers of the raised fabric in a direction substantially perpendicular to the rotation axis (the direction opposite to the rotation direction), it is possible to receive wind pressure, which makes it easier to receive wind and obtains a greater rotational force. It is possible to provide a suction tool with high wiping, sweeping and polishing performance.
[0033]
Next, the fibers of the raised cloth are laid down in one direction (substantially perpendicular to the rotation axis (the direction opposite to the rotation direction)), so that the fibers are generated only when the air hits them, and wind like a windmill. It becomes easy to receive, and a larger rotational force can be obtained, and a suction tool with high wiping, sweeping and polishing performance can be provided.
[0034]
In addition, the raised cloth is spirally wound around the outer periphery of the rotor, and by winding the raised cloth spirally, the air current collides toward the joint of the raised cloth, making it easier to receive wind, It is possible to provide a suction tool that has a higher rotational force and has high wiping, sweeping, and polishing performance.
[0035]

[0036]
In FIG. 5, the rotor 15a is provided with the blade | wing 12 used as a wind-receiving part with the raising cloth.
[0037]
The operation in the above configuration is as follows.
[0038]
The suction air generated when the cleaner body 7 is operated transmits the power by the wind pressure to the blades 19 together with the raised cloths of the rotors 15a and 15b, so that the rotors 15a and 15b rotate, and the surface to be cleaned After the dust is wiped, swept and polished, the dust is sucked into the cleaner main body 7 through the extension tube 2, the hand handle 4, the hose 6 and the hose joint 5.
[0039]
In addition to the fibers of the raised cloth, by providing the blades 19 for applying air to rotate the rotor 15a, the wind is received not only by the raised cloth but also by the blades that do not deform and do not leak even if the wind is received. Therefore, it is possible to provide a suction tool that has a higher rotational force and has high wiping, sweeping, and polishing performance.
[0040]
In this embodiment, the blades 12 are directly provided on the rotor 15a to transmit the power. However, the blades 19 are not directly provided on the rotor 15a, but are transmitted to the rotor 15a using a transmission mechanism such as a belt. Even if it transmits power, the same effect can be obtained.
[0041]

Next, a third embodiment of the present invention will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the same component as the said Example, The description is abbreviate | omitted.
[0042]
As shown in FIG. 10, the rotors 15 a and 15 b are rotated by a motor 22 through gears 23 and 24.
[0043]
The operation in the above configuration is as follows.
[0044]
When the vacuum cleaner body 7 is operated, electric power is supplied to the motor 22, and the rotors 15a and 15b rotate to wipe, sweep and polish dust on the surface to be cleaned. The vacuum cleaner body 7 is sucked through the hose 6 and the hose joint 5.
[0045]
According to the present embodiment, it is possible to provide a suction tool having a high dust collection performance, in which the rotational speed is more stable than that rotated by an air flow, and dust on the surface to be cleaned can be scraped with a larger force.
[0046]
In this embodiment, power is transmitted to the rotors 15a and 15b using the gears 23 and 24. However, the same applies to the case where power is transmitted to the rotors 15a and 15b using a transmission mechanism such as a belt. The effect of is obtained. Moreover, although the raising surface used the brushed cloth, a brush, felt, etc. can also be used.
[0047]
