Description

Description: TECHNICAL FIELD The present invention relates to an improvement of a floor brush of an electric cleaner.

[Prior Art] FIG. 4 is a plan sectional view of a conventional turbine brush used for an electric cleaner, and FIG. 5 is a side sectional view thereof.
Is a turbine brush, 2 is a casing, 3 is a suction port, 4 is a rotary brush, 5 is a turbine, 6 is a belt, 7 is a, 7b is a sealing material, and 8 is an exhaust port.

In the figure, if a hose connected to the cleaner main body is connected to the exhaust port 8 and the switch is turned on, dust on the floor is sucked together with the air from the suction port 3 and is carried to the cleaner main body from the exhaust port 8 through the turbine 5. The dust is removed in the cleaner body, and only the clean air is discharged from the cleaner body to the outside of the machine. During operation, the turbine 5 of the turbine brush 1 is driven by the passing air, and rotates the rotary brush 4 via the belt 6. The rotary brush 4 is detachably connected to the turbine 5 and rotates the rotary brush 4 when the object to be cleaned is a soft floor, but does not rotate the rotary brush 4 when the object is between a folding floor and a plate. This is because, in the case of a glutinous floor, the rotary brush 4 is effective for scraping out dust between the glutinous feet and cleaning, but the rotary brush does not work effectively between the plates or on the folding.

Note that, when dust is sucked by the turbine brush 1, a suction path is formed on a side surface of the turbine brush 1 indicated by an arrow 9 in FIG. 4 in order to increase the degree of vacuum of the suction port 3 and to easily suck dust from the floor surface. Usually it is limited. For this reason, one or two rows of rubber sheet sealing materials 7a and 7b are arranged on the lower surface of the turbine brush 1, and the lower portions thereof are brought into contact with the floor surface so that air is not sucked in the traveling direction of the turbine brush 1. It is composed.

FIG. 6 is a bottom view of the suction tool 10 without the rotary brush 4, and FIG. 7 is a central sectional view of the suction tool 10, in which 10 is a suction tool.
11 is a casing, 12 is a suction port, 13a and 13b are sealing materials, 14
Is a brush, 15 is a recess, 16 is a groove, 17 is a front wheel, and 18 is a rear wheel.

Also in this suction tool 10, the sealing members 13a and 13b abut against the floor surface, and air is sucked into the suction port 12 from both sides of the suction tool 10. Since the suction device 10 includes the concave portion 15 formed in front of the sealing material 13a and the groove 16 communicating with the concave portion 15, dust in front of the sealing material 13a when cleaning by pressing the suction device 10 is indicated by an arrow. As shown in the figure, the recess 15 and the groove 16 together with air
Through the suction port 12.

[Problems to be Solved by the Invention] By the way, the sealing materials 7a, b and 13a, b exhibit an effect as a sealing material between the plates or the like. The function of is difficult to recognize, and it has little value. Further, even between the plates or on the folding floor, it may not be preferable to completely seal in the direction of travel of the brush.

The present invention has been made in order to solve the above-described problems, and has as its object to provide an electric cleaner including a floor brush having a sealing material provided with a sealing function and a function other than the sealing function. Things.

[Means for Solving the Problems] An electric cleaner according to the present invention includes a suction port provided substantially at the center of a suction passage extending substantially linearly at the bottom of a floor brush, and both sides in the length direction of the suction port. The present invention provides an electric cleaner provided with a floor brush having a sealing material made of an elastic material provided on a surface of the sealing material and having a number of projections on a surface of the sealing material.

[Operation] By providing a myriad of projections on the surface of a sealing material made of an elastic material provided on both sides in the length direction of the suction port of the floor brush, not only the sealing function of the suction passage but also the floor can be reduced. When cleaning, a large number of protrusions of the sealing material scrape out dust between the hairs of Jutan, thereby improving the cleaning effect.
In addition, in the case of between the plates and on the folding floor, many small gaps are created between the sealing material and the floor surface due to the projections of the sealing material, from which dust is sucked into the brush, and the projections catch the rags. The cleaning is completed because it is sucked and sucked.

[Embodiment of the invention] Fig. 1 is an enlarged side view of a rotary brush of a cleaner during cleaning between plates, showing one embodiment of the present invention, and Fig. 2 is a view of the same during cleaning of a floor. Reference numeral 3 denotes a suction port, 4 denotes a rotary brush, 20a and 20b denote sealing materials, 21 denotes a projection thereof, 22 denotes a floor surface between plates, 23 denotes a floor surface, and 23a denotes a bristle foot.

As shown in the figure, the seal members 20a and 20b of the rotating brush 4 are formed of, for example, a rubber sheet having elasticity, and countless projections 21 are provided on portions of the surface thereof in contact with the floor surface. The shape of the projection 21 is a conical shape such as a conical shape or a pyramid shape, or a modification thereof. The shape, length and number of the projections, the length of the sealing material protruding from the bottom surface of the floor brush, and the like should be appropriately selected according to the specifications of the floor surface.

When cleaning a flat floor surface such as a space between the plates, when the floor brush is pressed, the lower surfaces of the sealing materials 20a and 20b are deformed in a direction opposite to the moving direction and come into contact with the floor surface 22. Hook and suck dust. Moreover, the sealing members 20a and 20b are more effective because they increase the degree of vacuum in the suction port 3.

In the case of a glutinous bed or the like, as shown in FIG. 2, the protrusion 21 scrapes out minute dust from the bristle feet 23a of the glutinous tube and sucks it from the suction port 3, so that the cleaning effect is improved.

In the case of a tatami floor, the protrusions 21 of the sealing material enter the irregularities on the surface of the tatami, scrape out the dirt on the irregularities, and suck the dust, so that cleaning is completed.

Although the above embodiment is an example in which the present invention is applied to a turbine brush, the present invention is not limited to the turbine brush, and the ordinary suction tool 10 also includes the projection 31 as shown in FIG. The same effect can be obtained by providing the sealing members 30a and 30b. As a result, it is possible to eliminate the brush 14 seen in the conventional example.

Further, in this embodiment, a rubber sheet is used as a sealing material, but the present invention is not limited to this, and plastics, a metal plate, or the like may be used.

[Effects of the Invention] In the electric cleaner according to the present invention, the countless projections are provided on the surface of the sealing material made of an elastic material provided on both sides in the length direction of the suction port of the floor brush. In addition to raising the degree of vacuum to increase the inhalation effect, when cleaning the space between the boards and the tatami floor or the floor, the protrusions scrape out the garbage and the fine garbage can be inhaled well,
The cleaning effect can be greatly improved.
