FIG. 5 is a perspective view of the vacuum cleaner in a state where the extension pipe is leaned, FIG. 6A is an upper rear perspective view of the main body of the vacuum cleaner, and FIG. It is a perspective view of the to-be-locked convex part of a machine.

  5 and 6, the conventional vacuum cleaner includes an electric blower (not shown) and a hose 2, an extension pipe 3, and a floor nozzle communicating with a cleaner body 1 including a filter (not shown) such as a paper pack. 4 is connected. A locking recess 6 is formed on the rear end surface 5 of the cleaner body 1, and a locking projection 7 is formed on the extension pipe 3 or the floor nozzle 4 so as to face the locking recess 6. . The extension tube 3 and the floor nozzle 4 can be held leaning by inserting and locking the locked convex portion 7 in the locking concave portion 6 (see, for example, Patent Document 1). .

  The operation of the conventional vacuum cleaner configured as described above will be described. When the electric blower is operated, an air flow is generated, and the air flow is sucked from the floor nozzle 4 together with the dust, and passes through the extension pipe 3 and the hose 2. Only air was discharged from the cleaner body 1 after the garbage was collected by the paper pack built in the cleaner body 1.

  Here, when the operation of the vacuum cleaner body 1 is temporarily stopped and the surroundings are cleaned up, the extended projection 3 and the floor nozzle 4 are moved by inserting and locking the locked projection 7 into the locking recess 6. The vacuum cleaner main body 1 can be stood and held easily, and the next time the vacuum cleaner main body 1 is re-operated, it can be used immediately, so it is easy to use.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

(Embodiment 1)
FIG. 1A is a perspective view of the upper rear surface of the vacuum cleaner main body of the vacuum cleaner according to the first embodiment of the present invention, and FIG. 1B is a perspective view of a locked convex portion of the vacuum cleaner. FIG.1 (c) is a back view of the to-be-latched convex part. In addition, about the component of the same structure as the said conventional vacuum cleaner, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

  1, the vacuum cleaner according to the present embodiment is provided with a permanent magnet 8 in a locking recess 6 formed in the rear end surface 5 of the vacuum cleaner body 1 and is locked in the extension pipe 3 or the floor nozzle 4. The protrusion 7 is provided with a holding member 9 made of a magnetic material such as iron, and the other configuration is the same as that of a conventional electric vacuum cleaner.

  The operation of the electric vacuum cleaner according to the present embodiment configured as described above will be described. In order to temporarily stop the operation of the vacuum cleaner main body 1 and clean up the surroundings, the extension pipe 3 and the floor nozzle 4 are cleaned. When leaning against the machine main body 1, the holding member 9 provided on the extension pipe 3 or the floor nozzle 4 is attracted by the permanent magnet 8 provided on the locking recess 6 formed on the rear end surface 5 of the cleaner main body 1 and the magnetic force (attraction force). Therefore, the extension tube 3 can be securely held without falling off and falling down.

  Moreover, if the clearance dimension of the latching recessed part 6 and the to-be-latched convex part 7 is made a little large, it will become easy to insert at the time of insertion, and the insertion property can also be improved.

  Next, when the vacuum cleaner main body 1 is re-operated, the extension pipe 3 can be removed and used immediately, so that the usability can be improved.

  The same effect can be obtained even if the permanent magnet 8 is the electromagnet 10, and the position of the locking recess 6 is not limited to the rear end surface 5 of the cleaner body 1.

(Embodiment 2)
FIG. 2 is an overall perspective view of the vacuum cleaner according to the second embodiment of the present invention, FIG. 3A is a top rear perspective view of the vacuum cleaner body of the vacuum cleaner, and FIG. The perspective view of the latching convex part of the vacuum cleaner, FIG.3 (c) is a back view of the latching convex part. In addition, about the component of the same structure as the said conventional vacuum cleaner, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

In the vacuum cleaner according to the present embodiment, an electromagnet 10 is provided in the locking recess 6, a permanent magnet 8 is provided in the locked projection 7, and a switch 11 for operating the electromagnet 10 is provided on the hand operating unit 12.

First, when the polarity of the permanent magnet 8 is set to the N pole (or S pole), the operation of the cleaner body 1 is temporarily performed halfway. When the extension tube 3 is erected in order to stop and clean up the surroundings, if the polarity of the electromagnet 10 of the locking recess 6 is changed to the S pole (or N pole) by the switch 11, the permanent magnet 8 of the locked protrusion 7 and During this time, an attractive force due to magnetic force acts, and the extension tube 3 is securely held firmly.

  Next, when the vacuum cleaner body 1 is re-operated, if the polarity of the electromagnet 10 is set to the N pole (or S pole) by the switch 11, the repulsive force due to the magnetic force works because it becomes the same polarity as the permanent magnet 8. Since the extension tube 3 can be easily removed, the usability can be further improved.

  In the above embodiment, the permanent magnet 8 is provided on the locked convex portion 7 and the polarity of the electromagnet 10 is switched by the switch 11. However, the holding convex portion 7 has the holding member of the first embodiment. 9 and the switch 11 may simply turn the electromagnet 10 on and off.

(Embodiment 3)
FIG. 4 is a block diagram for explaining the operation of the electric vacuum cleaner according to Embodiment 3 of the present invention. In addition, about the component of the same structure as the vacuum cleaner in the said embodiment, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The vacuum cleaner in the present embodiment includes a control circuit unit 13, a relay A 15 for the electric blower 14, and a relay B 16 for the electromagnet 10 provided in the locking recess 6. Other configurations are the same as those of the electric vacuum cleaner in the second embodiment.

  The operation of the vacuum cleaner according to the present embodiment configured as described above will be described. First, when the electric blower 14 is operated by turning on the relay A15 with the switch 11 of the hand operation unit 12, the control circuit unit 13 is operated. Thus, the relay B16 is turned off so that the electromagnet 10 provided in the locking recess 6 is not operated.

  Next, when the cleaning is interrupted and the relay A15 is turned off by the switch 11 and the electric blower 14 is stopped, the relay B16 is turned on and the electromagnet 10 provided in the locking recess 6 is operated, thereby extending the extension pipe. 3 or the holding member 9 provided on the floor nozzle 4, an attractive force due to magnetic force acts, so that the extension tube 3 can be reliably held.

  Next, when the operation of the cleaner body 1 is resumed, the extension tube 3 can be easily removed because the magnetic force of the electromagnet 10 is lost as described above.

  In this way, the operation of the electric blower 14 and the operation of the electromagnet 10 can be linked to further improve the usability.

  If a battery (not shown) or a double layer capacitor is used as a power source for operating the electromagnet 10, the magnetic force of the electromagnet 10 can be obtained even when the power cord (not shown) of the cleaner body 1 is removed from the outlet. Thus, the extension tube 3 can be securely held.

  As described above, the vacuum cleaner according to the present invention can reliably hold the extension tube and can be easily removed when the extension tube is stood against the cleaner body, so that the attachment or the like can be held on the body. It can be widely applied to household appliances and industrial equipment.
