Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vacuum cleaner that can be used both with a fixed suction spout and with a manual suction spout.

[Conventional technology]

Conventionally, so-called manual suction mouthpieces, in which the mouthpiece body is operated by holding an extension tube in the hand, are known, for example, as shown in Japanese Patent Publication No. 52-39263 and Japanese Utility Model Publication No. 54-10766, in which a general extension tube is attached to the mouthpiece body. It is constructed by attaching it.

A vacuum cleaner that can be used both for a fixed suction spout and for a manual suction spout has a configuration in which a dedicated manual suction spout and a dedicated fixed suction spout are provided, for example, as shown in U.S. Pat. No. 3,039,130. Therefore, the mouthpiece body of a fixed type mouthpiece is not configured to be used as the mouthpiece body of a manual type mouthpiece.

[The problem that the idea aims to solve]

Generally, when cleaning a large area of the floor, it is preferable to move the vacuum cleaner using a manual handle; in this case, a fixed suction It needs to be. With a fixed suction mouth, it is impossible to clean spaces where the cleaner body cannot be moved or areas higher than the floor surface. Therefore, it is necessary to change the fixed suction mouth to a manual suction mouth for cleaning.

The vacuum cleaner described in U.S. Pat. No. 3,039,130 can be used both as a fixed suction spout and as a manual suction spout, but it is necessary to separately provide a suction body for the fixed suction spout and a suction body for the manual suction spout. There is a problem with productivity.

The purpose of this invention is to make it possible to use the mouthpiece body of a fixed type mouthpiece as the mouthpiece body of a manual type mouthpiece, without deteriorating productivity. There is also a vacuum cleaner that can be easily used.

[Means to solve the problem]

The above object is to provide a vacuum cleaner equipped with a vacuum cleaner body provided with wheels for movement at the bottom and a handle for pushing by hand, and a fixed suction port removably provided at the suction port of the vacuum cleaner body. The fixed suction port includes an insertion part that is detachably inserted into the suction port of the vacuum cleaner body, a hose connected to the insertion part, a joint pipe connected to the hose, and a joint pipe that is detachably inserted into the joint pipe. It has a connected suction body, two reinforcing steel wires for preventing rotation of the suction body, and an auxiliary wheel provided at the center of the front part of the suction body, and the auxiliary steel wire has one end connected to the differential. The auxiliary wheel is fixed to a recessed part, and the other end is detachably attached between the mouthpiece body, and the lower end of the auxiliary wheel is located above the lowest end of the mouthpiece body, and the lower end of the auxiliary wheel is located above the lowest end of the mouthpiece body, and When the insertion part, the hose, the joint pipe, and the reinforcing steel wire are removed between the cleaner body and the vacuum cleaner body, a general hose and an extension pipe are detachably attached,
achieved.

[Effect]

According to this configuration, when moving the vacuum cleaner body across the floor by pushing the manual push handle,
Attach the fixed suction port to the suction port of the vacuum cleaner body.
In this case, the fixed type mouthpiece is pushed horizontally and the mouthpiece body is in the above-mentioned state of bending, and the mouthpiece body tries to dig into the floor surface, but the auxiliary wheels prevent it from digging into the floor and fix it smoothly. The suction port moves on the floor.

When cleaning areas that are higher than the floor or where the vacuum cleaner cannot fit, remove the insertion part of the fixed suction, hose, joint pipe, and reinforcing steel wire, and separate the suction and the vacuum cleaner from each other. Attach a general hose and extension pipe in between. This makes it possible to manually move the mouthpiece body by operating the extension tube.
The mouthpiece body of a fixed type mouthpiece can be used as the mouthpiece body of a manual type mouthpiece.

〔Example〕

Hereinafter, the present invention will be explained in detail based on the drawings showing one embodiment.

In the drawings, a fixed suction port 2 is detachably attached to a vacuum cleaner body 1 of a large-sized commercial vacuum cleaner. The attachment is performed by inserting the insertion part 3 of the fixed suction port 2 into the suction port 4 provided on the side surface of the cleaner body 1.

The fixed suction port 2 is an insertion part 3 into the vacuum cleaner body 1.
A short hose 5 connected to this insertion part 3, a joint pipe 6 connected to this short hose 5, a suction body 7 detachably connected to this joint pipe 6, and a rotation of this suction body 7. It is provided with two elastic auxiliary steel wires 8 and 8a for preventing this, and an auxiliary wheel 9 provided at the center of the front part of the mouthpiece body 7. short hose 5
is made of an elastic material such as rubber. The insertion part 3, the short hose 5, and the joint pipe 6 are integrated with adhesive.

The reinforcing steel wires 8, 8a have one end fixed to the insertion part 3, and the other end removably attached to locking holes 10, 11 provided at the left and right ends of the mouthpiece body 7. 8a serves to prevent rotation of the mouthpiece body 7 and to increase the rigidity of the fixed mouthpiece 2 as a whole.

The elasticity of the reinforcing steel wires 8, 8a and the short hose 5 allows the mouthpiece body 7 to follow the irregularities of the surface to be cleaned.

As shown in FIG. 3, the auxiliary wheel 9 has its lower end located above the lower end of the mouthpiece body 7 by a distance g. This is to bring the mouthpiece body 7 into close contact with the surface to be cleaned to some extent and to perform thorough cleaning, and experiments have shown that g=3 to 5 mm is appropriate. The auxiliary wheels 9 bear the suction force of the suction mouth body 7 to the surface to be cleaned due to the suction negative pressure of the vacuum cleaner body 1,
In addition, since it is located in front of the mouthpiece body 7, the force of the manual push operation of the handle 4 causes the mouthpiece body 7 to
prevents the surface from being pressed against the surface to be cleaned. As a result, the operating force for the suction mouth body 7 is only a slight frictional force between the surface to be cleaned and the suction mouth body 7, so the operation force is significantly reduced, making it easier to use.
On the other hand, when there is no auxiliary wheel 10, due to the adsorption force of the suction mouth body 7 to the surface to be cleaned, the frictional force between the suction mouth body 7 and the surface to be cleaned is much larger than that with the auxiliary wheels 9, making operation difficult. It becomes difficult.

After cleaning a wide area of the floor 13 with the fixed suction port 2, if you want to clean an area higher than the floor surface 13 where the fixed suction port 2 cannot fit, use the fixed suction port 2 to connect the insertion part 3 and When the short hose 5, joint pipe 6, and reinforcing steel wires 8, 8a are removed, the suction body 7 becomes a single item. By attaching a general long hose 14 and an extension pipe 15 to the main body 7, the mouthpiece body 7 can be freely operated manually.
That is, since the suction mouth main body 7 can be used as a manual suction mouth, the desired cleaning can be performed with one vacuum cleaner.

The vacuum cleaner main body 1 is provided with a plurality of moving wheels 16 on its bottom and can be moved smoothly by pushing the handle 12.

[Effect of idea]

As described above, according to the present invention, the mouthpiece body of a fixed type suction mouth can be used as the mouthpiece body of a manual type suction mouth, resulting in excellent productivity, and it is possible to easily switch between the use of a fixed type suction spout and a manual type suction type. can be done,
Moreover, a vacuum cleaner whose suction mouth body can be smoothly moved when used as a fixed suction mouth is obtained.
