Description

[Detailed Description of the Invention] This invention relates to a type of floor cleaner that sucks dust through a suction opening formed on the bottom surface of a main body case.

Conventionally, there has been a device in which a suction opening for housing a rotating brush is formed on the bottom surface of the main body case that has an electric blower and a dust collection section, but this has the drawback that it does not effectively suck in dust from the corners of the room. are doing.

The purpose of this invention is to create a floor cleaner that can eliminate the above-mentioned drawbacks.

An embodiment of this invention will be described based on the drawings.

1 is a flat main body case, wheels 2 are provided on both sides,
A bundle 3 is provided at the rear.

Further, an electric chamber 5 for housing an electric blower 4 and a distributed exhaust port 6 are formed in the rear part of the main body case 1, and a suction opening 8 with a bottom opening for rotatably housing a horizontally elongated rotating brush 7 in the front part. A vent 9 located at the center of this suction opening 8 is formed.

The main body case 1 has a dust case 10, which is a dust collecting section, which is removably fitted into the upper surface of the main body case 1, and a filter 11 is removably inserted into the dust case 10.

This dust case 10 is formed with a port 12 that communicates with the port 9 and a suction port 13 that opens on the top surface, and further includes a plate-shaped valve body that selectively opens and closes the port 12 and the suction port 13. 14 is rotatably attached while being biased upward by a spring 14a.

A backing 15 that prevents leakage between the vent 12 and the vent 9 and contacts the valve body 14 is inserted, and a backing 16 that contacts the valve body 14 is inserted into the suction port 131. has been done.

The electric blower 4 and the rotating brush 7 are connected by a belt 17.

Further, the valve body 14 is provided on the upper surface of the dust case 10.
A screw 18 that presses one side of the is screwed together.

As shown in FIGS. 4 and 5, it has a connecting part 19 connected to the suction port 13, and a horizontally long suction nozzle 20 that opens toward the floor on one front side of the main body case 1. A suction port body 21 is provided.

In such a configuration, as shown in FIG.
is urged upward to close the suction port 13 and open the vent 9.12, so the floor surface can be cleaned by driving the electric blower 4 and moving the main body case 1 along the floor surface. be exposed.

That is, the rotating brush 7 driven by the electric blower 4
Removes dust that adheres to the hair of carpets, etc. from the cleaning surface,
Dust is sucked in through the suction opening 8.

As a result, dust accumulates inside the dust case 10.

Then, the suction port body 21 is connected to the suction port 13 as shown in FIG.
When the suction nozzle 20 is connected to the floor surface at the front end of the main body case 1, it is possible to suck in dust from the corners of the room without leaving it behind.

At this time, the valve body 14 may be pushed by the connection part 19 of the suction port body 21, but as shown in FIG.
4 to the backing 15, the opening 12
leakage can be prevented.

In addition, as shown in FIG. 6, a telescopic hose 2 is connected to the suction port 13.
2, and an extension pipe 24 and a suction port body 23 such as a cockpit or a round brush may be connected to the end of the extension pipe 24.

In this way, even a vacuum cleaner dedicated to floor cleaning can clean the corners of a room without leaving any dust behind, and can also clean areas other than the floor.

In this case, by providing the bundle 3 with a holding portion 25 for holding the telescopic hose 22 and the extension tube 24, it is possible to organize the bundle when not in use and to facilitate handling.

Since this invention is configured as described above, by connecting a suction port body with a horizontally elongated suction nozzle to the suction port of the main body case, even if the vacuum cleaner is used exclusively for floor surfaces, it will not leave dust in the corners of the room. In addition to being able to be cleaned, the suction port body can also be connected to the suction port provided separately from the suction opening via a retractable hose, which has the effect of allowing cleaning of surfaces other than the floor surface. It is.
