EXAMPLE

<First Embodiment>

A first embodiment of the vacuum cleaner according to the present invention will be described with reference to Figs.

The vacuum cleaner of the first embodiment is constituted by a vacuum cleaner main body 1 including a dust collecting unit and an electric blower (not shown), and a hose 2 having one end side detachably attached to the vacuum cleaner main body 1. (See Fig. 1). The other end side of the hose 2 communicates with the floor suction port via a pipe (not shown). That is, the vacuum cleaner of the first embodiment is a canister type vacuum cleaner.

On the front upper surface of the vacuum cleaner main body 1, the dust cover 3 which closes and closes a dust collecting part freely is arrange | positioned. The dust cover 3 inserts a hand into the opening and closing portion 4 formed at the center of the front surface of the cleaner body 1, and opens the front surface of the dust cover 3 with a force greater than the locking force of the locking means (not shown). By lifting upward, the dust collecting part can be opened (see Figs. 1, 4 and 5). At the front of the cleaner main body 1, a suction port 5 is opened in communication with the dust collecting part, and one end side of the hose 2 is detachably inserted. Near the side of the suction port 5, the terminal insertion hole 6 which is electrically connected to an electric blower and which can be electrically connected to the hose 2 is formed (refer FIG. 6).

The joint part 7 is formed in the one end side of the hose 2. The joint portion 7 is formed with an insertion portion 8 into which the attachment and detachment is freely inserted in the suction port 5 of the cleaner body 1. In addition, the insertion portion 8 is inserted into the suction port 5 on the side surface of the joint portion 7 so as to be connected to the terminal insertion hole 6 and electrically connected to the electric blower via the terminal insertion hole 6. The terminal 9 is arranged. On the same surface as the terminal 9 of the joint part 7, the engaging part 10 which engages freely in the vacuum cleaner body 1 is arrange | positioned, and the engagement of the engaging part 10 is engaged. The hook 11 as a release means is arrange | positioned.

The engaging portion 10 and the hook 11 are urged outward by a taxing means (not shown), and the engaging portion 10 is engaged with the cleaner main body 1 in this state. When removing the hose 2 from the cleaner main body 1, by pressing the hook 11 inward, the engagement part 10 also moves inwards, so that the vacuum cleaner main body 1 of the engagement part 10 is removed. Since the engagement is released, the hose 2 can be removed (see Figs. 2 and 3).

The operation part 12 is formed in the upper surface of the joint part 7. In the operation part 12, the seesaw switch 13 which turns ON / OFF the drive of an electric blower by rotating, and the volume switch 14 which adjusts the output of an electric blower are located in the both sides which were out of the center of the hose 2, respectively.
