The display unit 52 indicating that the input of the electric blower is controlled according to the amount of dust by the operation unit 51 and the detection means provided on the connection pipe 3 is provided in front of the handle unit 33.

  The operation unit 51 is composed of a plurality of switches. As shown in FIG. 8, each switch is operated in a horizontal direction or in a fan shape within a range where a finger can reach from a position where the handle is gripped. Since the part 51 becomes larger in the horizontal direction and the cleaning floor surface becomes difficult to see, each switch for controlling the electric blower of the cleaner body 1 that is frequently used is within the range where the finger can reach from the position where the grip part is held. Further, the width of the operation portion 51 is reduced by disposing the ON / OFF switch of the motor of the suction body 8 that is disposed at substantially the same distance and that is less frequently used away from the grip portion.

A terminal (not shown) for detachably connecting a terminal connected to the power supply line of the connection tube 7 and a connection tube 7 are provided between the upper side of the first tube 31 on the connection tube 7 side and the cover body 40A.

After the lead wire is held by the extending portion 42, the holding portion 44 is fixed to the extending portion 42 so as to cover the lead wire in order to prevent the lead wire from coming off during assembly. As shown in FIG. 6, the lower surface of the extended portion 42 is formed in the concave portion 43 so as not to interfere when the second tubular body 32 rotates.

  Further, a support column 70 is provided substantially upward from the vicinity of the bent portion of the first tubular body 31, and a connecting body 71 that connects the lower cover body 40A and the lower cover body 40B is inserted into the outer periphery of the support column 70. It is fixed.

  Further, as shown in FIG. 10, below the handle portion 33, a projecting portion 80 is provided integrally with the lower cover body 40 on the end surface of the extending portion 42 to assist the lifting of the suction body 8.

  Further, as shown in FIG. 7, the handle portion 33 is formed so that the cross-sectional shape thereof is a substantially elliptical shape in which the length y in the vertical direction is 1.0 to 1.2 times the length x in the width direction. is doing.

  The operation of the above configuration is as follows.

  When cleaning, the user holds the handle 33 and moves the mouthpiece 8 back and forth. At this time, an operation such as changing the suction force is performed. Since the operation unit 51 is provided within a range where the finger can reach from a position where the grip unit is gripped and at substantially the same distance, the grip unit is gripped. Multiple operation units can be operated without having to change the position.

  That is, as shown in FIG. 8 (a), the switch provided in the operation unit 51 indicates that each switch 51a for controlling the electric blower 4 of the cleaner body 1 that is frequently used from the position where the handle is gripped. The switch is frequently used by disposing the ON / OFF switch 51b of the motor of the suction body 8 that is less frequently used in the lateral direction within the reach of the grip part and at substantially the same distance from the grip part. Can be operated without changing the position of the grip. Moreover, even if the switch 51b with low frequency of use is disposed slightly away from the grip portion, it is not inconvenient in the actual cleaning work, and conversely, the cleaning workability can be improved by reducing the lateral width of the operation section 51. Further, the switch operability is given top priority, as shown in FIG. 8B, the switch 51a for controlling the electric blower 4 is laterally or fan-shaped so as to be located at substantially the same distance from the position where the handle 33 is gripped. The ON / OFF switch of the motor of the suction body 8 that is provided less frequently may be used by pressing one of the switches 51a for controlling the electric blower 4 twice.

  Here, the front portion of the handle portion 33 provided with the operation portion 51 is formed to have a wider width than the rear portion, and a plurality of operation portions 51 are provided. 51 can be provided within the reach of the finger, improving usability.

  In this vacuum cleaner, the angle α formed by the central axis B1 of the first tube body 31 (that is, the central axis A1 of the connecting pipe 7) and the central axis C2 of the second connecting portion is 90 ° to 160 °. Since it is set, when the user stands with the handle portion 33 of the hand handle body 6 in cleaning, the suction hose 2 hangs diagonally downward so that the cleaner body 1 can be easily It can be moved by being pulled and can be prevented from interfering with the hand holding the handle portion 33. Furthermore, the angle β between the central axis B1 of the first tube 31 (ie, the central axis A1 of the connecting pipe 7) and the central axis B2, the central axis C1 of the first connecting portion 34, and the central axis of the second connecting portion 35. Since the angle γ formed with C2 is provided so as to be substantially the same angle, the second connection portion is formed by the rotation of the first connection portion 34 of the second tubular body 32 with respect to the first tubular body 31. Since the center axis C2 of 35 can be substantially parallel to the center axis B1 of the first tube 31 (that is, the center axis A1 of the connecting pipe 7), the dust transport path can be made substantially straight. , Can improve the breathability.

  Further, as shown in FIG. 9, when cleaning a low place such as under the bed, in FIG. 9 (c1) and (c2), the suction hose 2 is stretched so that the connecting pipe 7 is in a horizontal state. 9 (b1) and 9 (b2), the connecting pipe 7 is horizontal, but the suction hose 2 protrudes sideways, so that the suction hose 2 becomes a hindrance when the width direction is narrow, In this embodiment, as shown in FIGS. 9 (a1) and (a2), the second tube body 32 is rotated by about 180 ° with respect to the first tube body 31 to thereby perform suction. Since the hose 2 can be made substantially level with the first tube body 31 being at the same height, the connecting pipe 7 can be laid in a substantially horizontal state, and the suction hose 2 is also substantially parallel to the connecting pipe 7. It is easy to go to a narrow place or a low place to the back. It is possible to sweep, also becomes good usability in this respect. Further, as shown in FIG. 6, the lower surface of the extending portion 42 of the first tubular body 31 is formed in the concave portion 43 so as not to interfere when the second tubular body 32 rotates. Without increasing the height, the distance between the first tubular body 31 and the suction hose 2 becomes closer, the connecting pipe 7 can be laid down lower, and the usability is further improved.

  On the other hand, since the rear part of the lower cover body 40 is curved and is a closed space toward the rear side, when performing a cleaning operation with the handle part 33, it is pushed by the palm when pushing, and the finger belly when pulling. It is possible to prevent the hand from separating even if the handle portion 33 is not firmly grasped during cleaning. Further, conventionally, the angle formed by the lower cover body 40B and the central axis A1 of the connecting pipe 7 is 50 ° to 90 °, and when cleaning the floor surface, the connecting pipe 7 and the mouthpiece 8 are connected to each other. The pushing force is easy to transmit, but when moving the suction body 8 by cleaning the stairs, etc., it was difficult to lift because the angle with the central axis A1 was large. In the embodiment, the angle formed between the lower cover body 40B and the central axis A1 of the connecting pipe 7 is set to be 20 ° to 45 ° so that the angle with the central axis A1 is not as large as possible. It can be operated without changing the position of the gripping part, either in front-rear operation or in lifting operation such as stairs cleaning. Further, since the suction body 8 rotates a rotating brush (not shown) by the electric motor in the same direction as the traveling direction, when the suction body 8 is pushed by floor cleaning, the suction body is caused by the resistance force between the rotary brush and the floor surface. Since 8 moves forward, a large force is not required for pressing, and there is no problem in usability even if the angle with the central axis A1 is small.

  Further, as shown in FIG. 10, by providing the convex portion 80 below the handle portion 33, when the suction body 8 is lifted such as when cleaning the stairs, the lower side of the hand is applied to the convex portion 80, The lifting force can be reduced. In the present embodiment, the convex portion 80 is integrated with the lower cover body 40, but the same effect can be expected as a separate part. Of course, the convex portion 80 may be provided on the extended portion 42 or the upper cover body 41. Further, even if the convex portion 80 is movable and can be fixed at an arbitrary position, it can be used in various sizes of hands, so that the usability is improved.

  Further, as shown in FIG. 7, the grip portion 33 has a vertically long cross-sectional shape, so that the grip feeling is improved and the operation of rotating the hand handle body 6 to the left and right is also performed in the horizontal area of the handle portion 33. Is easy to operate. In addition, since it is important for the human hand to grip the little finger side firmly when gripping an object, if the handle portion 33 is formed in a tapered shape with the operation portion 51 side thicker and the convex portion 80 side thinner, Usability is further improved due to a firm grip. In addition, by using the tapered shape, it is possible to adjust even a person with various hand sizes so as to grasp the position of the desired thickness, thereby further improving the grip feeling. In addition, even if the grip portion 33 is formed in a constricted shape near the center, it can be adjusted so that people with various hand sizes can grasp the position of the desired thickness, thereby further improving the grip feeling.

  Further, the handle 33 may be covered with a soft body, formed into a corrugated shape that follows a finger when the lower surface is gripped by actual cleaning, and further the antibacterial treatment is applied to the soft body. Can be further improved.

  When lifting the suction body 8, stress concentrates on the connection body 71, but a column 70 is integrally provided substantially above the vicinity of the bent portion of the first tubular body 31, and a cover is provided on the outer periphery of the column 70. Since the connecting body 71 connecting the lower body 40A and the lower cover body 40B is inserted and fixed by screwing, sufficient strength can be secured.

  As described above, the electric vacuum cleaner according to the present invention can provide an easy-to-use hand handle body that can operate the operation unit without changing the grip portion from the state in which the handle portion is grasped, and is a highly operable vacuum cleaner. It can be provided.
