2. Description of the Related Art Conventionally, as a vacuum cleaner which can be deformed in accordance with a place to be cleaned, a vacuum cleaner body is detachably fixed to a support pipe, so that it is used only as an upright and only a vacuum cleaner body. There is a dual-purpose vacuum cleaner that can be used in a handy state. 2. Description of the Related Art A conventional dual-purpose vacuum cleaner includes a cleaner body, a hose, a support pipe, a rotary bend, and a suction port.

[0003] In a conventional dual-purpose vacuum cleaner, when it is deformed into a state of use as an upright, hooks projecting about two places up and down from the side surface of the support pipe are formed on the lower surface side of the cleaner body. The lower surface of the cleaner main body can be detachably fixed to the side surface of the support pipe by fitting into the recessed portion. In such a vacuum cleaner, when used as an upright, the cleaner main body is arranged upward in consideration of connection with a hose.

The main body of the vacuum cleaner houses a suction motor and a dust collection chamber, and sucks air together with dust, and after filtering dust with a paper pack or a filter, exhausts the air. 2. Description of the Related Art In a conventional vacuum cleaner, an exhaust hole is formed in a side surface of a cleaner body to exhaust air.

[0005] This exhaust hole is usually provided in a direction other than the longitudinal (front-back) direction with respect to the cleaner main body so that dust on the floor is not rolled up or the face of the worker is not exposed to exhaust when used as an upright. Orientation, i.e., horizontal, specifically, side, up, or down with respect to the cleaner body.

[0006]

However, in the conventional vacuum cleaner, since the exhaust hole is directed sideways, upward or downward with respect to the main body of the vacuum cleaner, various problems occur in the use of the handy state. .

For example, when the exhaust hole is directed sideways or downward (in the direction of arrow B in FIG. 6) with respect to the main body of the cleaner, the distance between the main body of the cleaner and the surface to be cleaned such as the floor surface. However, there is a problem that dust on the surface to be cleaned is rolled up by the exhaust air. On the other hand, when the exhaust hole is directed upward (in the direction of arrow C in FIG. 6) with respect to the cleaner body, there is a problem that the exhaust air hits the face of the worker.

SUMMARY OF THE INVENTION The present invention has been made to solve such a problem. In both the use state and the handy state as an upright, the exhaust air does not hit the surface to be cleaned and the face of the worker. It is intended to provide a vacuum cleaner.

[0009]

The vacuum cleaner of the present invention comprises:
A suction pipe, a support pipe connected to the suction port, and a cleaner body detachably attached to the support pipe;
A vacuum cleaner that can be used in an upright use state and in a handy state used only by the cleaner body, wherein exhaust holes are formed at a plurality of locations on an outer surface of the cleaner body, and the use state as the upright is described. And the handy state can switch the direction of the exhaust gas exhausted from the exhaust hole to the outside.

A first exhaust hole is formed in a side portion of the cleaner body, and a second exhaust hole is formed in a rear portion of the cleaner body.
It is preferable to have first shielding means for opening and closing the exhaust hole and second shielding means for opening and closing the second exhaust hole.

It is preferable that the first shielding means is a shutter that can be opened and closed.

It is preferable that the second shielding means is a hook rib for hooking the cleaner body, and the second exhaust hole is a fitting hole fitted to the hook rib.

The first shielding means is an openable and closable shutter, the second shielding means is a hook rib for hooking the cleaner body, and the second exhaust hole is fitted to the hook rib. Preferably, the shutter automatically opens and closes as the hooking rib is inserted into and removed from the fitting hole.

The electric vacuum cleaner of the present invention uses a shutter that can be freely opened and closed, a hooking rib for locking the main body of the vacuum cleaner, or the like as a shielding means, for example, by shielding an exhaust hole on the outer surface of the main body of the vacuum cleaner. The direction of the exhaust flow exhausted from the exhaust hole on the outer surface of the cleaner main body can be switched between the use state as the upright and the handy state. Therefore, in either of the two use states, the exhaust air does not hit the floor and the face of the worker.

FIG. 6 is an enlarged view of a part of the main part of the vacuum cleaner of FIG. 1, FIG. 6 is an explanatory view showing a state in which the vacuum cleaner main body of FIG. 1 is used in a handy state, and FIG.

As shown in FIGS. 1 to 7, the vacuum cleaner according to the present embodiment is used as an upright because the cleaner main body 1 is detachably fixed to a support pipe 2 (FIG. 1). This is a dual-purpose vacuum cleaner that can be used in a state where the cleaner body 1 is detached from the support pipe 2 (not shown) and in a handy state where only the cleaner body 1 is used (see FIG. 6). Vacuum cleaner body 1 with support pipe 2
In the state of being removed from the handle, the handle 13 is gripped and used in a hand-held manner.

The vacuum cleaner shown in FIGS. 1 to 4 has a vacuum cleaner main body 1, a support pipe 2, a rotary bend 3,
It comprises a rotary pipe 4, a suction port 5, and a hose 6.

As shown in FIG. 5, the cleaner body 1
A dust collection room 21 and an electric blower room 22 are housed inside. The electric blower room 22 houses a suction motor 23. In order to exhaust the air exhausted from the suction motor 23 to the outside, the outer surface of the cleaner body 1 is
Different types of exhaust holes are formed.

First, as a first exhaust hole, a side exhaust hole 24 formed of a plurality of slits is formed on both side surfaces of the cleaner body 1 so as to communicate with the electric blower chamber 22. Further, shutters 25 for opening and closing the side exhaust holes 24 are provided on both side surfaces of the cleaner body 1 as first shielding means so as to be openable and closable. The shutter 25 has two opposing edges 25 a and 25 b guided by guide frames 26 provided on both side surfaces of the cleaner body 1. Reciprocate.

As a second exhaust hole, a fitting hole 1c is formed at a rear portion of the cleaner main body 1, specifically, at a rear end of the lower surface 1b so as to communicate with the electric blower chamber 22. In the state of use as an upright, as the second shielding means,
The upward hook rib 4d (see FIG. 2) of the rotary pipe 4 fits into the fitting hole 1c.

As shown in FIG. 1, the support pipe 2 has an upper end opening 2 a connected to a suction port 1 a of the cleaner body 1 through a hose 6. A grip 7 to be held by hand is fixed to the upper part of the support pipe 2.

As shown in FIG. 2 to FIG.
Is fixed to the front side of the support pipe 2 detachably by a fixing method described later.

The support pipe 2 and the rotary bend 3 are detachably connected by a C-ring 30 (see FIG. 2) so as not to rotate. The rotary bend 3 and the rotary pipe 4 are rotatably connected. In addition, reference numeral 8 shown in FIG. 4 denotes a lock piece for preventing the rotary pipe 4 from coming off the rotary bend 3, and 9 denotes a hollow rotary shaft formed integrally with the lower end 4 c of the rotary pipe 4. The rotation shaft 9 is rotatably connected to the rear of the suction port 5.

In the vacuum cleaner configured as described above,
When deformed to a use state as an upright, first, as shown in FIGS.
By fitting a downward fitting hole 1c formed at the rear end of b into an upward hook rib 4d provided on the rotary pipe 4, the lower portion of the cleaner body 1 is fixed. Then, the cleaner body 1 is brought into contact with the support pipe 2 so that the downward clamp hook 10 provided on the support pipe 2 is fitted into an upward recess 1 d formed at the front end of the lower surface 1 b of the cleaner body 1. If so, the lower surface 1b of the cleaner body 1 can be fixed to the outer surface of the support pipe 2 as shown in FIG. On the other hand, when the vacuum cleaner main body 1 is detached from the support pipe 2 and used in a handy state, the clamp hook 10 is pulled out from the concave portion 1d by sliding the release knob 10a of the clamp hook 10 upward. Then, it may be removed in the reverse procedure of the above-described fixing method.

As shown in FIGS. 1 and 5, in the use state as an upright, the shutter 25 is opened by hand, and the air exhausted by the suction motor 23 is exhausted from the side exhaust holes 24 to the outside. On the other hand, as shown in FIG. 4, the fitting hole 1c is
By being fitted by d, it is almost airtightly closed. Therefore, air is hardly exhausted from the fitting hole 1c.

Accordingly, in the state of use as an upright, the exhaust air is exhausted in a substantially horizontal direction through the side exhaust holes 24, so that dust on the floor surface may be rolled up,
No defects such as hitting the worker's face.

Further, if the openings are inclined slightly upward as in the case of the side exhaust holes 24 in FIG. 5, it becomes more difficult to wind up dust on the floor surface.

On the other hand, as shown in FIGS. 6 and 7, in a handy state in which only the cleaner main body 1 is used, the shutter 25 is closed by hand and the side exhaust holes 24 are airtightly closed. In the handy state, the hooking rib 4d is detached from the fitting hole 1c at the rear portion of the cleaner body 1, so that the fitting hole 1c is open.

Therefore, as shown in FIG. 6, in the handy state, the exhaust air is exhausted to the rear of the cleaner main body 1 (in the direction of arrow D in FIG. 6) through the fitting hole 1c. Therefore, even if the distance between the cleaner body 1 and the surface to be cleaned, such as the floor, is short, the dust on the surface to be cleaned is not rolled up and the worker's face (usually on the extension of arrow C in FIG. 6). ).

Similarly to the above-described handy state, the shutter 25 is also used in a state where the cleaner main body 1 of FIG. When used, the exhaust air does not hit the surface to be cleaned and the face of the worker.

In this embodiment, an example in which the shutter is opened and closed by hand has been described. However, the present invention is not limited to this, and it is assumed that the hooking rib is inserted into and removed from the fitting hole. The shutter may be detected by known detection means such as a contact sensor, and the shutter may be automatically opened and closed by a known drive means such as a linear motor in accordance with the detection. There is no trouble of forgetting to open and close. As another example of the structure for automatically opening and closing the shutter, a structure using mechanical interlocking may be adopted.

Further, in this embodiment, the direction of the exhaust air is adjusted by opening and closing the shielding means provided in each exhaust hole, but the present invention is not limited to this. The present invention includes any mode as long as it can switch the direction of the exhaust flow exhausted from the exhaust hole to the outside between the use state as an upright and the handy state.

[0033]

According to the present invention, the exhaust air does not hit the surface to be cleaned and the face of the worker in both the use state as the upright and the handy state. Thereby, optimal cleaning can be performed in each use state.
