  Moreover, the hand operation part 43 is provided so that it may become one step lower than the handle part 42, and the upper surface of the hand operation part 43 is a substantially flat surface. With such a configuration, the switch 48 of the hand operating unit 43 can be easily pressed, and the operability is further improved.

  In addition, since the hand operating unit 43 has a switch with a relatively high use frequency in front and a switch with a relatively low use frequency in the back, the operability is particularly good for a switch with a high use frequency. It is.

  Further, the central axis C of the hand operation unit 43 forms an angle α upward with respect to the central axis A of the first connecting pipe unit 411. Therefore, in a state where the user stands and cleans the floor surface, as shown in FIG. 6, the hand operation unit 43 faces upward, the user's visibility is improved, and the hand operation unit 43 is reliably operated. Can do. Further, in this case, the notification lamp 49 provided on the hand operation unit 43 can be easily seen from the user, and can be cleaned while confirming the strength of the electric blower and the rotating state of the rotary brush. Here, FIG. 6 shows a state in which the connection pipe 5 is extended to the maximum so that the height from the floor surface to the hand handle 4 is 75 cm.

  Further, the central axis C of the hand operation part 43 has an angle β upward with respect to the central axis B of the second connecting pipe part 412. Therefore, especially when the connection pipe 5 is stood and cleaned with respect to the floor surface, or when the hand is cleaned using a brush attachment, the hand operation unit 43 faces upward and the operability is good. It is. FIG. 7 is a schematic diagram when the central axis A is set to 60 ° with respect to the floor surface as an example of cleaning the connection pipe 5 with respect to the floor surface.

  As described above, the central axis C of the hand operation unit 43 has an angle upward with respect to the central axis A of the first connecting pipe part 411 and the central axis B of the second connecting pipe part 412, so that the user Even when the front of the floor is cleaned or when the user's feet are cleaned by standing the connecting pipe 5 with respect to the floor, the hand operating unit 43 can be seen well by the user and the operability is improved. Will improve.

  Further, the tip of the hand operation unit 43 has a hemispherical shape with a rounded corner, so that it is difficult to hit the hand operation unit 43 against furniture or a wall during use, and damage to the furniture, the wall, or the hand handle itself. Can be prevented. Moreover, the effect of preventing damage is further enhanced by forming the distal end of the hand operation unit 43 with a flexible material or an elastic member.

  Further, a convex portion 44 is provided below the handle portion 42, and when the handle portion 42 is gripped, the index finger or middle finger of the holding hand can be put on the convex portion 44. Therefore, the operability when the hand handle 4 is moved back and forth can be improved, and the user can naturally hold an appropriate gripping position.

  The connecting portion 41 is formed so that the central axis A and the central axis B form an angle γ smaller than 180 °. Therefore, when the user holds the handle portion 42 while standing, the connection hose 3 hangs diagonally downward, so that the cleaner body 2 can be easily pulled and moved. You can avoid getting in the way. In the first embodiment, γ is 160 °, and the above-described good usability can be obtained. On the other hand, if γ is set to be smaller than 180 °, dust transfer efficiency decreases due to the resistance of the dust transfer path inside the connecting portion 41, and therefore γ is preferably 90 ° or more.

Further, the support column 45 extends upward from the vicinity of the connection terminal 435 of the connecting portion 41 and is connected to the hand operating portion 43. The lead wire 433 passes through the support column 45. By adopting such a configuration, the lead wire to be used can be shortened as compared with the case where the lead wire 433 is passed through the handle portion 42. Thereby, cost reduction can be expected, and malfunction due to disconnection of the lead wire 433 in the middle can be prevented. Moreover, since the support | pillar 45 has connected the hand operation part 43 and the connection terminal 435 vicinity of the connection part 41, the length of a lead wire can be shortened especially.
