BACKGROUND OF THE INVENTION
The present invention relates to the structure of a vacuum cleaner, and in particular, provides a new proposal for a method for supporting a vacuum cleaner when not in use.
[0002]
[Prior art]
In a vacuum cleaner that pulls the vacuum cleaner body through the suction hose and moves on the floor surface, various support structures have been devised in order to make the movement light. The vacuum cleaner 1 shown in FIG. 11 is also an example, and the housing 11 of the vacuum cleaner main body 10 is formed in a drum shape, and both ends of the drum-shaped housing 11 (this is the “side surface” of the vacuum cleaner main body 10. The wheel 12 having a diameter larger than that of the cleaner body 10 is attached. An electric blower 13 is disposed inside the cleaner body 10, and a suction hose 14 is connected to a connection port 22 at the front center of the cleaner body 10. A connection pipe 16 is connected to a joint portion 15 provided at the tip of the suction hose 14, and a suction port body 17 is connected to the tip of the connection pipe 16. The joint part 15 has a handle part 18, and an operation panel for operating the vacuum cleaner 1 is provided on the surface of the handle part 18. The joint unit 15 is provided with a cyclone dust collector 19.
[0003]
When the electric blower 13 is driven in the vacuum cleaner 1 of FIG. 11, air is sucked from the suction port body 17. When the suction port body 17 is moved on the floor surface f, dust on the floor surface f is sucked into the suction port body 17 together with air, enters the cyclone dust collector 19 through the connection pipe 16, and the airflow there Dust is separated and captured from. The airflow after the dust separation enters the cleaner body 10 through the suction hose 14, is sucked into the electric blower 13, and is then discharged out of the cleaner body 10 through an exhaust port (not shown). This vacuum cleaner 1 has a large diameter of the wheel 12 and thus has a high performance of overcoming obstacles and can be easily routed around the house.

Since the electric vacuum cleaner 1 has good running properties, if it is left unattended, it may roll in an unnatural direction. Therefore, when not in use, the vacuum cleaner body 10 is caused so that the axis of the wheel 12 is vertical. Then, one of the wheels 12 serves as a pedestal, and supports the cleaner body 10 on the floor surface f. If the hook 21 on the side of the connection pipe 16 is engaged with the hook 20 formed on the vacuum cleaner body 10, the suction hose 14, the connection pipe 16, and the suction port body 17 are held in the connected state in the vacuum cleaner body 10. It is possible to store all the elements of the vacuum cleaner 1 in a small-area space.
[0005]
[Problems to be solved by the invention]
When the vacuum cleaner 1 is not in use, the vacuum cleaner body 10 is erected with one wheel 12 as a pedestal, and the connection pipe 16 is held on the side surface thereof, so that the overall vacuum cleaner 1 is quite tall and unstable. Further, the wheel 12 has a diameter that exceeds that of the vacuum cleaner main body 10, and despite the fact that the ratio of the wheel 12 occupying the surface area of the vacuum cleaner 1 is extremely large, the fact that the large-area side surface is effectively utilized. It's hard to say. Therefore, the present invention pays attention to the large area of the wheel 12 as described above, and improves the stability of the posture when not in use, and improves the usability of the vacuum cleaner 1 by preparing a storage location for the accessory parts. The purpose is to utilize this part.

[0015]
The seat plates 33a and 33b have a circular side shape, and their diameters are slightly smaller than the diameters of the recesses 31a and 31b. Therefore, the wheels 12a and 12b rotate without contacting the seat plates 33a and 33b except for the side surfaces of the hubs 32a and 32b. Appropriate anti-rotation means such as uneven engagement is provided between the axles 30a, 30b and the seat plates 33a, 33b so that the seat plates 33a, 33b are not rotated by the wheels 12a, 12b and the screws 34 are not loosened. Keep it.
[0016]
Wheel caps 37a and 37b having substantially the same diameter as these are attached to the seat plates 33a and 33b. In order to attach the wheel cap 37a, a hinge portion 38a is formed on one side of the periphery of the seat plate 33a. The wheel cap 37a is connected to the hinge portion 38a by a shaft 39a so as to be freely opened and closed. That is, the wheel cap 37a is hinged to the axle 30a via the seat plate 33a.
[0017]
Closed state maintaining means 56a is provided at the open / close end of the wheel cap 37a. The closed state maintaining means 56a includes an iron piece 40 fixed to the back side of the wheel cap 37a and a magnet 41 fixed to the seat plate 33a correspondingly. As the magnet 41 attracts the iron plate 40, the wheel cap 37a is maintained in a state of closing the recess 31a. A pulling recess 42a is provided near the open / close end of the outer surface of the wheel cap 37a, and the wheel cap 37a can be rotated around the shaft 39a by pulling it with a hand.

Forms a notch 43 for receiving a portion where the wheel cap 37a is combined with the hinge portion 38a. The notches 43 are provided at a total of four locations at intervals of 90 °.
[0019]
In this embodiment, the combination of the magnet 41 and the iron piece 40 is used as the closed state maintaining means 56a of the wheel cap 37a, but this may be replaced with other holding means. For example, a fabric connecting means or a snap button known as a trademark name Velcro fastener can be used instead.
[0020]
A hinge portion 38b for hinge coupling the wheel cap 37b is also formed on one side of the periphery of the seat plate 33b. A wheel cap 37b is connected to the hinge portion 38b by a shaft 39b. Closed state maintaining means 56b is also provided at the open / close end of the wheel cap 37b. The closed state maintaining means 56b includes a pulling handle 44 provided on the wheel cap 37b side and a hook portion 46 provided on the seat plate 33b side.
[0021]
A pulling recess 42b is provided at the open / close end of the wheel cap 37b, and a pulling handle 44 having an L-shaped cross section is attached to the wheel cap 37b so as to be rotatable around an L-shaped bent portion. One arm of the puller 44 is a hook portion 45, and the hook portion 45 engages with a hook portion 46 formed on the seat plate 33b to keep the wheel cap 37b closed. The puller 44 is biased by a spring (not shown) so as to engage the hook portion 45 with the hook portion 46. When the other arm of the puller 44 is pulled and pulled, the puller 44 rotates against the spring, the hook part 45 comes off from the hook part 46, and the wheel cap 37b rotates about the shaft 39b. Can do. The wheel cap 37b also rotates in a plane including the axis of the wheel 12b. However, since the wheel 12b does not have a notch 43 such as the notch 43 of the wheel 12a, the wheel cap 37b cannot be opened from the closed state to 180 °. Can not.
[0022]
A space between the wheel cap 37b and the seat plate 33b serves as an accessory storage chamber 50 for storing cleaning accessories such as a gap nozzle and a furniture brush. The accessory part holding means 51 is fixed to the side surface of the seat plate 33b. The accessory part holding means 51 is formed of a synthetic resin rich in elasticity, and has as many C-shaped holder portions as the number of accessory parts to hold the accessory part in between. 1 and 2 show a state in which the gap nozzle 52 is held.
[0023]
A handle 55 is fixed to the outer surface of the wheel cap 37b. This handle 55 is used to cause the cleaner body 10.
[0024]
Next, the effect | action of the vacuum cleaner 1 of 1st Embodiment is demonstrated. The axes of the wheels 12a, 12b are leveled, both the wheels 12a, 12b are grounded to the floor surface f, and the suction hose 14 is connected to the connection port 22 of the cleaner body 10. When the connection pipe 16 and the suction port body 17 are connected to the suction hose 14 and the electric blower 13 is driven, dust on the floor surface f is sucked together with air from the suction port body 17. The air stream containing dust enters the cyclone dust collector 19 through the connection pipe 16, where the dust is separated and captured. The airflow after the dust separation enters the cleaner body 10 through the suction hose 14, is sucked into the electric blower 13, and is then discharged out of the cleaner body 10 through an exhaust port (not shown).
[0025]
If the suction hose 14 is pulled, the cleaner body 10 moves on the floor surface f. At this time, the wheels 12a and 12b rotate, but the wheel caps 37a and 37b do not rotate because the seat plates 33a and 33b to which these wheels are attached do not rotate. That is, the pulling recesses 42a and 42b maintain the angular positions of the upper half of the wheels 12a and 12b that are easy to put on. While the wheels 12a and 12b are rotating, the wheel caps 37a and 37b are kept closed by the closed state maintaining means 56a and 56b. Therefore, even if the accessory part holding means 51 does not hold the accessory part well, the accessory part does not roll out.
[0026]
When the cleaning is completed, the hand cap 42a of the wheel cap 37a is pulled and the iron piece 40 is pulled away from the magnet 41 to open the wheel cap 37a. Next, the handle 55 is grasped, the cleaner body 10 is raised so that the axes of the wheels 12a and 12b are vertical, and the wheel cap 37a is lifted so that it can be reversed. At this time, the angle of the wheel 12a is adjusted so that one of the four cutouts 43 is aligned with the hinge portion 38a. Then, the wheel cap 37a is completely rotated by 180 ° to project outside the wheel 12a, and the wheel 12a and the wheel cap 37a are lowered onto the floor surface f. A wheel cap 37a projects from the outside of the wheel 12a, and both areas are added to form a wide base, on which the cleaner body 10 stands. The hook 21 on the side of the connection pipe 16 is engaged with the hook 20 of the cleaner body 10, and the suction hose 14, the connection pipe 16, and the suction port body 17 are held in the cleaner body 10 while being connected. The suction port body 17 is placed on the wheel cap 37a. If there is an accessory part that has been taken out and used, the wheel cap 37 b is opened and returned to the accessory part holding means 51 of the accessory part storage chamber 50.
[0027]
Since the wheel cap 37a acts as an auxiliary leg for posture stabilization of the electric vacuum cleaner main body 10, the electric vacuum cleaner 1 can be stably stored. The hook 20 of the vacuum cleaner main body 10 is provided at a position aligned with the wheel cap 37a opened 180 °. When the hook 21 of the connection pipe 16 is engaged with the hook 20, the suction port body 17 is automatically moved to the wheel. It rests on the cap 37a. Thereby, the weight of the suction inlet 17 or the connection pipe 16 is applied to the wheel cap 37a, and the storage posture of the vacuum cleaner 1 is further stabilized. When it is necessary to change the storage location, the cleaner body 10 can be lifted and moved by grasping the handle 55.
[0028]
FIG. 4 shows a second embodiment of the present invention. In this embodiment, the accessory part holding means 51 is fixed to the wheel cap 37b instead of the seat plate 33b, and the accessory parts such as the gap nozzle 52 and the furniture brush 53 are held by this.
