Abstract

PROBLEM TO BE SOLVED: To eliminate blowing away and rising of dust by exhausted air and to improve the usability by providing a windshielding body to prevent exhausted air flowing in from an exhaust vent from flowing downward. SOLUTION: The vacuum cleaner main body 1 is provided with an electric blower 2 and an exhaust vent A 3, and also with axis parts 4 crossing the advancing direction at both side ends of the main body 1. A wheel 5 is freely rotatable with the parts 4 and provided with a wheel axis provided with a powl for fixing the wheel 5 to the main body 1 in an axial direction. An exhaust vent B7 is provided on the side surface of the main body 1 and a windshielding rib 8 which is nearly annular, opens its upper side and is formed to be close to the inner wall surface of the wheel 5 is provided in addition. Exhaust A9 exhausted from the blower 2 is made to flow out from the vent A3. In addition, exhausted B10 different from the main vent A9 is made to flow out from an exhaust vent B7 to reduce noise. The exhaust B7 flowing out from an exhaust vent B has its flow regulated by the rib 8 and never flows out to a floor surface, thereby the blowing away and rising of dust on the floor surface by the exhausted B is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a form of exhaust of a vacuum cleaner.

[0002]

2. Description of the Related Art A conventional vacuum cleaner will be described with reference to FIGS.

[0003] Reference numeral 21 denotes a cleaner main body provided with an electric blower 22 and an exhaust port A23, and has a shaft portion 24 intersecting the traveling direction on both side surfaces of the main body. Reference numeral 25 denotes a wheel having a wheel shaft 26 which is rotatable with respect to the shaft portion 24 and also has a claw fixed to the main body 21 in the axial direction. Further, it had an exhaust port B27 provided on the side surface of the main body 21 and on the mounting surface of the wheel 26.

[0004]

In the conventional vacuum cleaner, the exhaust A28 discharged from the electric blower 22 flows out of the exhaust port A23. In recent years, in order to reduce noise, the exhaust gas is separated into a plurality of exhaust gas A28 and a plurality of exhaust gas B29, and the exhaust gas B29 is discharged from the exhaust port B27. However, as shown in FIG. 8, the exhaust gas B29 flowing out of the exhaust port B27 hits the wheel 25 and flows out in each direction. As a result, the exhaust gas B29 flowing out to the floor particularly blows off the dust on the floor and flies up, so that the usability is poor.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a vacuum cleaner in which dust is not blown off by air discharged from an electric blower and flew up, the usability is improved, and a low-noise vacuum cleaner is conventionally provided.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides an electric blower, an exhaust port A for discharging a part of exhaust gas from the electric blower, and a shaft arranged on a side surface of the main body. A wheel rotatably fixed to the shaft portion, and an exhaust port B provided on the side surface of the main body and discharging exhaust toward an inner wall surface of the wheel, and exhaust gas flowing out from the exhaust port B. In a vacuum cleaner provided with a windshield that regulates the flow so as not to flow downward, dust on the floor surface is blown off by restricting the exhaust flowing out of the exhaust port B from flowing downward by the windshield. It is an object of the present invention to provide a vacuum cleaner that eliminates fluttering, improves usability, and has low noise as before.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION
An electric blower, an exhaust port A for discharging a part of exhaust air from the electric blower, a shaft disposed on a side surface of the main body, a wheel rotatably fixed to the shaft portion, and provided on a side surface of the main body.

According to a fourth aspect of the present invention, the wheel has an annular protruding wall which is opposed to the inner peripheral surface or the outer peripheral surface of the annularly formed rib body through a small gap. .

The invention according to claim 5 of the present invention is characterized in that the exhaust port B
And a duct forming an exhaust passage between the side surface of the main body and the side surface of the wheel.

[0012]

(Embodiment 1) Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.

1 and 2, reference numeral 1 denotes a cleaner main body provided with an electric blower 2 and an exhaust port A3, and has a shaft portion 4 intersecting the traveling direction on both side surfaces of the main body. The wheel 5 is rotatable with respect to the shaft portion 4, and has a wheel shaft 6 having a claw for fixing the wheel 5 in the axial direction on the main body 1. The side face of the main body 1 has an exhaust port B7, and a windshield rib 8 which is formed in a substantially annular shape and has an upper opening and is close to the inner wall surface of the wheel 5.

The operation of the above configuration is as follows.
Exhaust gas A9 discharged from the electric blower 2 flows out of the exhaust port A3. In recent years, in order to reduce noise, exhaust B10 different from the main exhaust A9 is discharged from the exhaust port B7. The flow of the exhaust B7 flowing out of the exhaust port B is regulated by the windshield ribs 8 and is not discharged to the floor.
Usability can be improved and a low-noise vacuum cleaner can be provided as before.

(Embodiment 2) Next, a second embodiment of the present invention will be described with reference to FIG. The same components as those in the first embodiment are denoted by the same reference numerals, and description thereof will be omitted.

The same components as those in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted. An annular protruding wall 13 is formed integrally with the wheel 5 so that the inner peripheral surface and the outer peripheral surface of the annular windshield rib 8 are opposed to each other via a small gap 12.

The operation of the above configuration is as follows.
By providing the wheel 5 with the annular protruding wall 13 that is opposed to the inner and outer peripheral surfaces of the windshield rib 8 via the small gap 12, the gap is reduced, and the exhaust B7 can be reliably regulated.
When an impact is applied to the wheel 5, the impact is applied to the windshield rib 8 and the annular projecting wall 13, and also to the shaft portion 4 and the wheel shaft 6. Therefore, the impact applied to the shaft portion 4 and the wheel shaft 6 is reduced. The exhaust gas B7 can be reliably regulated, and the durability of the wheels 5 is improved. Contrary to the above configuration, the windshield rib 8 formed integrally with the wheel 5 and opposed to each other with a small gap between the inner peripheral surface and the outer peripheral surface of the annular protruding wall 13 is formed integrally with the cleaner body 1. Thus, the same effect as in the above configuration can be obtained, and the number of annular protruding walls 13 provided on the wheel 5 is reduced from two to one, so that sink of the wheel 5 as an external part can be prevented, and the external quality can be improved. Can be improved.

(Embodiment 4) Next, a fourth embodiment of the present invention will be described with reference to FIGS. The same components as those in the above embodiment are denoted by the same reference numerals, and description thereof will be omitted.
