Further, as shown in FIG. 2, a hose cover 39 is provided on the outer periphery of the suction hose 2 attached to the second tubular body 32.

  As shown in FIG. 4, the first tube body 31 and the second tube body 32 are assembled to complete the hand handle body 6, and the suction hose 2 and the connecting pipe 7 are attached to the hand handle body 6. The angle α formed by the central axis B1 of the first tubular body 31 (that is, the central axis A1 of the connecting pipe 7) and the central axis C2 of the second connecting portion is set to be 90 ° to 160 °. Further, the angle β between the central axis B1 of the first tube 31 (that is, the central axis A1 of the connecting tube 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. The angle γ formed with C2 is set to be substantially the same angle. In this embodiment, α is 145 ° and β and γ are 17.5 °.

  The handle portion 33 covers the upper portion of the first tubular body 31, and is below the cover body 40A extending from the vicinity of the bent portion of the first tubular body 31 to the suction hose 2 side in the substantially extending direction of the connecting tube 7. The cover body lower part 40B is composed of a cover body lower part 40B that is curved toward the connecting pipe 7 from the end surface of the extending part of the cover body lower part 40A, and the cover body upper part 41 covers the upper part of the cover body lower part 40B. An angle θ between the cover body 41 and the central axis A1 of the connecting pipe 7 is set to be 30 ° to 50 °. Between the lower cover body 40 </ b> B and the upper cover body 41, a control unit 50 that controls the electric blower of the cleaner body 1 and the electric motor of the suction body 8 is housed, and the control unit 50 is operated. The operation unit 51 and a display unit 52 indicating that the input of the electric blower is controlled according to the amount of dust by the detection means provided in the connection pipe 3 are provided in front of the handle unit 33.

  The operation unit 51 is composed of a plurality of switches. As shown in FIG. 8, when all the switches are provided in the horizontal direction or in a fan shape, the operation unit 51 becomes larger in the horizontal direction, and the cleaning floor surface becomes larger. Since it may become difficult to see, the ON / OFF switch of the motor of the suction body 8 that is less frequently used is arranged farther from the grip portion than the switch that controls the electric fan of the vacuum cleaner body 1 that is frequently used. As a result, the width of the operation unit 51 is reduced.

  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. A hook body 61 for connecting and fixing to the first tube body 31 is held. Further, the first tube body 31 has an extended portion 42 that extends from the vicinity of the bent portion of the first tube body 31 toward the suction hose 2 in the substantially extending direction of the connection tube 7, similarly to the lower cover body 40 </ b> A. A lead wire for supplying power from the power supply line of the suction hose 2 to the control unit 50 is held between the extending portion 42 and the lower 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 extending 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.

  Since the angle α between the central axis B1 of the first tubular body 31 (that is, the central axis A1 of the connecting pipe 7) and the central axis C2 of the second connecting portion is set to be 90 ° to 160 °, When the user stands while holding the handle 33 of the hand handle body 6 during cleaning, the suction hose 2 is slanted downward, and the cleaner body 1 can be easily pulled and moved. This is to prevent the hand having the handle 33 from getting in the way. 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, when cleaning a low place such as under the bed as shown in FIG. 9, in FIG. 9 (c), the suction hose 2 is stretched, so that the connecting pipe 7 may be in a horizontal state. In FIG. 9 (b), the connecting pipe 7 is horizontal, but the suction hose 2 projects sideways, so the suction hose 2 becomes an obstacle in a narrow width direction, and the workability is reduced. In this embodiment, as shown in FIG. 9A, the suction hose 2 is moved to the first tube body by rotating the second tube body 32 by about 180 ° relative to the first tube body 31. 31 so that the connection pipe 7 can be laid in a substantially horizontal state, and the suction hose 2 can be substantially parallel to the connection pipe 7, It is possible to easily clean a narrow place or a low place to the back, Also a good user-friendly in terms of. 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.

  As shown in FIG. 8 (a), the switch provided in the operation unit 51 has a switch that controls the electric blower 4 of the cleaner body 1 that is frequently used in the switch arranged in the lateral direction at substantially the same distance from the grip part. By disposing the ON / OFF switch of the motor of the mouthpiece 8 that is used less frequently away from the grip portion, the switch that is used frequently can be operated without changing the position of the grip portion. In addition, even if a switch that is less frequently used 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, with the operability of the switch as the top priority, as shown in FIG. 8B, the switch for controlling the electric blower 4 is arranged in a horizontal direction or a fan shape so as to be located at substantially the same distance from the position where the handle portion 33 is gripped. The ON-OFF switch of the motor of the suction body 8 that is provided and used less frequently may be used by pressing the switch that controls the electric blower 4 twice.

Since the rear part of the cover body 40 is curved and is a closed space toward the rear, when carrying out the cleaning work with the handle part 33, it is pushed with the palm when pushing and hooked with the belly of the finger when pulling. It is possible to prevent the hand from separating even if the handle 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 the front-rear operation or in the lifting operation such as cleaning the stairs. Further, since the suction body 8 rotates a rotating brush (not shown) in the same direction as the traveling direction by an electric motor, 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.

  As shown in FIG. 10, by providing the convex portion 80 below the handle portion 33, the lower side of the hand is applied to the convex portion 80 during the lifting operation of the suction body 8 such as cleaning the staircase. It can be a fulcrum and 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. Further, even if the convex portion 80 is detachable or movable and can be fixed at an arbitrary position, it can be used in various sizes of hands, so that the usability is improved. Furthermore, usability is further improved if the surface of the convex portion 80 is formed as a concave portion so as to follow the hand.

  As shown in FIG. 7, by making the cross-sectional shape of the handle portion 33 into a vertically long cross-sectional shape, the grip feeling is improved and the operation of rotating the hand handle body 6 to the left and right also has a lateral area of the handle portion 33. Increase and 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 vacuum cleaner according to the present invention can reduce the operating force when lifting the mouthpiece, can provide a hand handle body with good usability, and can provide a highly operable vacuum cleaner. is there.
