Description

[Detailed Description of the Invention] a) Field of Industrial Application This invention relates to an improved creation of a vertical cleaner equipped with a cyclone type dust collecting mechanism.

B) Conventional technology Conventionally, as a prior art relating to this type of vacuum cleaner, Japanese Patent Publication No.
Nos. 50140 and 62-50141 were known.

These prior arts have a bottomed cylindrical outer cyclone and an inverted conical inner cyclone that is housed inside this outer cyclone, and from the dust inlet to the outer cyclone tangentially from the outer cyclone. The present invention relates to a vertical cleaner of a type having a flow path from the inner cyclone to the suction fan device in a tangential direction of the top of the inner cyclone, in which coarse dust particles sucked together with air have low efficiency. The outer cyclone separates and deposits, and then the highly efficient inner cyclone separates and deposits the remaining fine dust and particles.

(C) Problems to be Solved by the Invention However, in the above-mentioned conventional technique, all the air circuits from the dust suction port to the suction fan device via the cyclone are formed in the closed housing, and dust is often formed. However, there was a problem that it was easy to get clogged and that maintenance work could not be performed when dust clogs.

The present invention has been made in view of the above problems of the prior art, and an object of the present invention is to provide an air circuit which is less likely to be clogged with dust in a cyclone vertical cleaner and which is easy to maintain.

D) Means for Solving the Problem That is, in the vertical cleaner of the above-mentioned type, the present invention has two hollow columns for supporting the cyclone device from the base of the cleaner having the dust suction port and the suction fan device. Standing upright,
Use one of these stanchions as part of the air flow path from the dust inlet to the cyclone device and the other stanchion as part of the air flow path from the cyclone device to the suction fan. And a cyclone device, and an outer cyclone and an inner cyclone in the cyclone device are connected by detachable flexible hoses to form an air circuit.

As a development of this invention, this application also discloses a invention characterized in that a nested filter is inserted between the support on the suction fan side and the flexible hose in the air circuit.

(E) According to the above-mentioned former invention, between the support column extended from the dust inlet and the cyclone, the outer cyclone inside the cyclone and the inner cyclone, and the column extended to the cyclone and the suction fan device. That is, since the portion where the circuit should be bent is connected by the detachable flexible hose, by removing this hose, there is an effect that the portion where the dust is most likely to be clogged in the circuit can be inspected.

Further, according to the latter device, since the nested filter is inserted between the support on the suction fan side and the flexible hose,
Even if the cyclone is ventilated, the particles still remaining are trapped by this filter, and the effect is that the filter can be easily inspected and replaced by detaching the hose.

F) Embodiments Embodiments of these inventions will be described below with reference to the accompanying drawings.

For convenience of explanation, a vacuum cleaner that implements all of the above ideas will be described as an example.

This vacuum cleaner consists of a cylindrical outer cyclone with a bottom and an inverted conical inner cyclone housed inside this outer cyclone, and from the dust inlet to the tangential direction of the top of the outer cyclone,
It is a vertical cleaner having a flow path from the outer cyclone to the top of the inner cyclone, and from the inner cyclone to the suction fan device.

In the figure, reference numeral 1 is a pedestal of a vacuum cleaner, and a suction fan device 20
And a handle 23 for the entire vacuum cleaner is erected on the rear side, the cleaner head 2 is pivotally fixed to the front part, and the rotating brush 3 is provided below the cleaner head.
The suction port 2a in which is arranged is opened.

A pair of columns 4a and 4b are erected from both sides of the pedestal 1 in a plane, and a socket 5 is pivotally fixed between the columns 4a and 4b.

The socket 5 is provided with an inverted conical inner cyclone 10 whose lower end is opened in advance.

Reference numeral 6 in the drawing denotes an outer cyclone, which is fitted between the socket and the upper surface of the base 1 when the socket 5 is upright.

Then, a dust collection container 7 for communicating with the inner cyclone 10 and for accommodating the dust separated by the inner cyclone is fitted into the bottom portion of the outer cyclone 6.

In the above structure, the flow path of the air taken in is secured as follows (see FIG. 3).

First, the pillar 4a is made hollow, the lower end of the pillar is communicated with the cleaner head 2 of the pedestal 1, and the upper end of the pillar is communicated with the cleaner 5 through the flexible hose 17 in the tangential direction in the socket 5. Head 2 to outer cyclone 6
A flow path leading to is secured.

Next, the outer cyclone 6 is connected to the inner cyclone 10 through the flexible hose 18 in the tangential direction, so that the flow path from the outer cyclone 6 to the inner cyclone 10 is secured.

Finally, the remaining column 4b is hollow, the upper end of the column is communicated with the inside of the cyclone 5 via the flexible hose 19, and the lower end of the column is communicated with the passage to the suction fan device 20 of the pedestal 1. This ensures a flow path from the inner cyclone 10 to the suction fan device 20.

By the above series of flow paths, the suction port of the cleaner head 2
The dust-containing air sucked from 2a is sucked in the tangential direction in the outer cyclone 6 through the support column 4a and the flexible hose 17,
Coarse dust is removed and accumulated by performing a swirling motion here, and further air is sucked in a tangential direction in the inner cyclone 10 through the flexible hose 18, where fine dust and fine dust are generated by performing a swirling motion at a higher speed. Particles are removed and accumulated, and only clean air passes through the flexible hose 19 and the pillar 4b, and the suction fan 20
The action discharged by the device will be realized.

By the way, reference numeral 42 in the figure denotes a filter inserted between the support 4b on the suction fan side and the flexible hose 19.

The filter 42 is formed in a nested shape having a filter mesh inside and is attached / detached between the columns 4b as required (see FIGS. 1 and 2).

The filter 42 originally has a function of removing particles remaining in the air, but in some cases, a fragrance may be filled in the filter 42 to allow it to emit a fragrance into the room by exhaust from the vacuum cleaner. Good.

Reference numeral 41 in the figure is a gutter-shaped catcher into which a flexible hose 19 connecting the inner cyclone 10 and the support 4b on the suction fan side is to be fitted. The catcher is provided on the upper part of the socket 5 and its shape is changed. By making it like a handle, it also functions as a handle for carrying the entire vacuum cleaner.

G) Effect of device This device, which is configured as described above, has the following unique effects.

(A) As described in the section of the action, since the bent portion of the circuit where the dust is most likely to be clogged in the circuit is connected by the detachable flexible hose, even if dust clogging occurs at this part, this hose should be It can be easily removed by removing it.

(B) In this case, since the flexible hose is bent, it protrudes from both sides of the cleaner as shown in FIG. 1 and functions as a bumper when the cleaner rolls over or collides with a wall, which is effective. You can get a good buffering effect.

(C) In the case of the second invention, since a part of the circuit is connected by a detachable flexible hose and the nested filter is inserted therein, the filter can be easily inspected and replaced.

(D) Similarly, if a fragrance is inserted in addition to or in place of the filter, the vacuum cleaner can also be used as a fragrance generator, and the scent desired by the user can be easily refilled.

(E) If the gutter-shaped catcher, into which the flexible hose connecting the inner cyclone and the support on the suction fan side is to be fitted, has a handle-like shape as in the embodiment, the space above the cleaner is not only neat. In addition, the number of assembly steps and the number of parts are reduced.
