  Next, the detailed structure of the functional means of the suction tool 4 is demonstrated using FIGS.

  In front of the lower member 12 of the suction tool 4, a suction port 19 having a certain opening dimension facing the surface to be cleaned 80 in the front-rear direction of the suction tool 4 and approximating the width dimension is formed. Reference numeral 22 denotes a rotating brush configured by sticking the soft member 23 and configured as a rod-shaped shaft body, and is a component for picking up dust accumulated on the surface to be cleaned 80. In the configuration of the rotary brush 22, rotary bearings 24-a and 24-b are provided at both ends, and one side of the rotary brush 22 is driven to transmit drive from a rotary drive means provided separately inside the suction tool 4. A gear 26 that connects the belt 25 is provided.

  Further, the rotary brush 22 is disposed on the upper surface of the suction port 19 and inside the suction tool 4, and one rotary bearing of the rotary brush 22 is provided on a guide body 27 provided at the inner end of the suction tool 4.

As a result, the suction force on the surface to be cleaned 80 of the suction tool 4 can be adjusted based on the adjustment of the degree of vacuum in the rotating brush chamber 34.

  A turbine chamber 35 is provided at the rear of the rotary brush chamber 34 as shown in the drawing and forms a suction path from the dust suction port 42 to the vacuum cleaner body 1 thereafter. Similar to the rotating brush chamber 34, it is a space portion partitioned by wall surfaces 31 and 33 having stamping fitting portions extending from the upper member 13 and the lower member 12, and is configured as a suction path. An air turbine 30 that mainly serves as a rotational drive source for the rotary brush 22 and a rotary arm 9 having a connection portion 54 for connecting to the extension pipe 3 are disposed. The configuration of various functional means arranged in the turbine chamber 35 will now be described.

  Reference numeral 30 denotes a plurality of blades 36 extending in the longitudinal direction, and an air turbine formed in a substantially cylindrical shape by forming side walls 37 at both ends thereof, and a shaft body 38 penetrating the center of the side wall 37 and projecting to one side is formed. At the same time, there are provided a bearing part 39 for reducing rotational frictional resistance, a drive belt 25 for transmitting rotation to the rotary brush 22, and a gear 40 for mounting and reducing the rotation. In the bearing part 39, metal bearings 39-a impregnated with lubricating oil are provided at both ends, and a part having a substantially cylindrical shape having a grease injection part at an intermediate part thereof is provided. Is inserted in a rotatable manner. Further, a small-diameter gear 40 is press-fitted and fixed to the shaft body 38 so as to be non-rotatable at the tip thereof, and is motivated by the rotation of the air turbine 30 and attached in a configuration. In the configuration including the outer shape of the periphery, a drive belt 25 that transmits rotation is provided at the tip of the bearing part 39 that protrudes in the lateral direction from the air turbine 30 to the side end of the suction tool 4. By doing so, it is set as the structure which makes the outer shape which similarly formed the holding part which covers those functional means protrudes to the side end of the suction tool 4. FIG. In the outer shell structure to project, the turbine chamber 35 and the rotating brush are provided by two upper and lower outer shells extending from the upper member 13 and the lower member 12 with a minimum clearance for avoiding interference with the functional means. Like the chamber 34, the upper and lower parts are sandwiched and fitted. In particular, in the outer configuration covering the driving belt 25 and the like connected by the side end of the front rotating brush 22 of the suction tool 4 and the tip of the bearing part 39 protruding from the center of the rear turbine chamber 35, the functional means (rotating brush) 22, the turbine chamber 35, the bearing component 39, and the drive belt 25) are arranged in a substantially square shape with four sides, and a through-hole-shaped space hole 14-a that does not form an outer shell is formed at the center. ing.

  Further, in the outer portion having the through hole-like space hole portion 14-b at the opposite position with the central turbine chamber 35 of the suction tool 4 as a boundary, although no functional means is disposed inside, the suction tool It is configured as an outer portion for preventing an inclination due to a difference in mass balance between right and left (in a so-called aerial state) during lifting. Further, as shown in FIG. 8, the space holes 14-a and 14-b can be hooked to a hanging storage hinge A or the like in the house. The rotary arm 9 can be attached to and detached from the extension pipe 3 serving as a connection means to the cleaner body 1 in a substantially cylindrical air channel portion 53 provided with rotary shafts 51 and 52 at both ends over the entire width of the turbine chamber 35. The connecting portion 54 is configured and is rotatably arranged and held by a shaft support structure in which the upper wall 13 and the lower member 12 hold the wall surfaces 31 and 33 from above and below. Further, the air turbine 30 is disposed inside the wind tunnel portion 53. With respect to the arrangement, the shaft body 38 projecting to one side from the air turbine 30 and the bearing part 39 are passed through the rotating shaft 52 of the rotating arm 9 so that the rotating arm 9 can be continuously rotated. The rotation stop point is determined by the contact of the connecting portion 54 within the cut-off range 55 of the upper member 13, and is arranged as a coaxial structure so as to be rotatable up and down.

  A second suction port 20, which is a lattice-like hole penetrating the lower member 12 of the suction tool 4, is provided on the inner lower surface of the turbine chamber 35. The second suction port 20 is closed when the suction tool 4 is grounded to the surface 80 to be cleaned. When the suction tool 4 is lifted, the second suction port 20 is changed from the closed state to the open state and sucks outside air. Further, since the second suction port 20 is formed at a position not facing the air turbine 30, the sucked outside air follows a path 81 that does not pass through the air turbine 30, so that the dust suction port 42 and the air turbine are simply used. The pressure reduction of the path | route air volume 82 which passes 30 acts. That is, the driving force of the air turbine 30 that is the rotation driving means of the rotating brush 22 is reduced, and the effect of similarly reducing the number of rotations of the rotating brush 22 exposed when the suction tool 4 is lifted is produced. This is a component that plays a role of a safety device for reducing the risk.

  A wall-like member 62 made of soft bristle is disposed around the outer surface of the lower member 12 in which the second suction port 20 is formed, and around the lower surface facing the surface to be cleaned 80. The wall-shaped member 62 compensates for the shortage of closure due to the gap 63 corresponding to the height of the roller 32 generated when the suction tool 4 is grounded to the surface to be cleaned 80 such as a hard wooden floor. The length 64 is formed longer than the roller 32 height. In the dust collection performance of the suction tool 4 in a grounded state with respect to the surface to be cleaned 80, the degree of vacuum that leads to the dust suction action increases with the closing level of the second suction port 20, so that an improvement in the closing level is required. Is.

(Embodiment 2)
Next, the structure of the suction tool in Embodiment 2 of this invention is demonstrated using FIG.9 and FIG.10. As shown in FIG. 9, the structure is largely the same as that of the first embodiment, and a part of the upper member 13 and the lower member 12 are penetrated, and the space provided in two places on the left and right sides of the turbine chamber 35 in the center of the suction tool 4. In the holes 14-a and 14-b, a guide body 91 made of a soft material is provided in the inner contour portion. In the detailed configuration, as shown in FIG. 10, the upper and lower groove portions 92 and 93 of the guide body 91 having a substantially H-shaped cross section project from the side surface of the turbine chamber 35 and rotate forward from the side end of the suction tool 4. The upper member 13 and the lower member 12 of the outer portion connected to the brush chamber 34 are nipped and fitted to be attached. In particular, in the attachment range, the through hole-like space hole portions 14-a and 14-b are arranged over the entire inner contour portion. As for the operation in this configuration, in addition to enabling the hanging storage hinges and the like in the house as described in the first embodiment, a soft material is formed between the hinges and the like. By interposing the guide body 91, the suction tool 4 can be prevented from being damaged by interference.

(Embodiment 3)
Next, the structure of the suction tool in Embodiment 3 of this invention is demonstrated using FIG.11 and FIG.12. In particular, the main components and the arrangement configuration are the same as those in the first embodiment, and a configuration that is partially changed will be described below. The upper member 13 and the lower member 12 are penetrated, and the closed surface 101 is formed in the space holes 14-a and 14-b provided in two places on the left and right sides of the turbine chamber 35 in the center of the suction tool 4, and the upper part of the suction tool 4 In addition, the recesses 102 and 103 are formed in the lower part, and the through-hole 107 and the lid part 104 that can be opened and closed are attached to the wall surface of the rotating brush chamber 34 of the outer upper recess part 102. As shown in FIG. 12, the lid part 104 is a part in which a knob 105 is formed on a curved plate base material facing the inner wall of the rotating brush chamber 34, and is provided on the inner wall of the outer portion of the rotating brush chamber 34. The holding rib 106 is attached so as to be slidable. At the time of normal use in the suction tool 4, it is used as being always closed, and is opened only at the time of the user's arbitrary opening / closing operation. With respect to the operation in this configuration, the strength of the suction tool 4 is improved because it acts as a reinforcing wall for the space holes 14-a and 14-b that are penetrated, and dust is absorbed from the front of the suction tool 4 by forming the recess 102. Since it is possible to use it as a part for temporarily collecting coarse dust picked up by the user, and the communication with the suction path is achieved by the opening of the lid part 104, an extension pipe or the like by removing the conventional suction tool 4 etc. This eliminates the need for a dust-absorbing treatment operation from the large-diameter portion of the dust-absorbing means, thus improving the usability. In addition, since the opening is made only at the time of arbitrary appropriate opening and closing operation, it is configured to prevent the degree of vacuum in the rotating brush chamber 34 in the normal state, and the dust collection performance is not deteriorated.

(Embodiment 4)
Next, the structure of the suction tool in Embodiment 4 of this invention is demonstrated using FIG.13 and FIG.14. The main components and the arrangement configuration are the same as those in the third embodiment, and a configuration that is partially changed will be described below. A through-hole 115 and a lid part 110 that can be opened and closed are attached to the wall surface of the turbine chamber 35 of the outer upper recess 102. As shown in FIG. 14, the lid component 110 is a component in which a knob 111 is formed on a plate-shaped base material, which is opposed to the inner wall of the turbine chamber 35, and is held on the inner wall of the outer portion of the turbine chamber 35. The rib 112 is slidably attached by the rib 112. During normal use of the suction tool 4, it is closed and opened only by an operation according to the needs of the user. The operation in this configuration is substantially the same as in the third embodiment, but compared to communicating with a one-point suction port, a separate inlet is formed at a site with a high degree of vacuum. Thus, the usability can be further improved.

  As described above, since the vacuum cleaner or the vacuum cleaner according to the present invention can be stored and treated with coarse dust on the basis of the reduction in size and weight, it can be applied to uses such as improving usability.
