Description

The present invention relates to a suction body of an electric vacuum cleaner.

2. Description of the Related Art Conventionally, there is a suction body used in an electric vacuum cleaner in which a rotary cleaning body having a cleaning member attached in a spiral shape is provided in an intake chamber having a suction port opened on a lower surface facing a surface to be cleaned.

In such a suction body, if the state of the dust transporting section can be seen from the outside, it is convenient to easily confirm the situation when lint or the like is caught on the rotary cleaning body.

Therefore, a suction port body has been proposed in which the upper case of the suction port body is formed of a translucent member so that it can be confirmed from the outside whether or not the rotary cleaning body inside is rotating normally (Patent Reference 1).

JP, 2005-261721, A

However, in Patent Document 1, it is possible to easily confirm the catching of lint or the like on the rotary cleaning body, but it is not possible to confirm when the toothpick or the like is caught on the substantially cylindrical portion of the dust conveying unit.

It is an object of the present invention to provide a suction body having a structure capable of easily confirming the inside of the substantially cylindrical portion of the dust transfer unit from the outside, and an electric vacuum cleaner having the suction body.

The present invention is characterized by including an air intake chamber having a suction port opened on a lower surface facing a surface to be cleaned, and a substantially cylindrical portion of a dust transfer portion, and at least a part of the substantially cylindrical portion is made of a transparent member. To do.

According to the present invention, it is possible to easily confirm the inside of the substantially cylindrical portion of the dust transfer portion, and it is possible to provide the suction body of the electric vacuum cleaner in which it is easy to find a defect such as when a toothpick is caught in the substantially cylindrical portion. ..

It is an external view of the electric vacuum cleaner which concerns on 1st Embodiment. It is an external view of the suction tool for floors which concerns on 1st Embodiment. It is a vertical sectional view of the conventional floor suction tool. It is a vertical cross-sectional view of the floor suction tool according to the first embodiment. It is a vertical cross section of the suction tool for floors which concerns on 2nd Embodiment.

Hereinafter, a first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows an external view of an electric vacuum cleaner according to a first embodiment of the present invention. The electric vacuum cleaner 1 includes a cleaner body 2, a hose 3 extending from the cleaner body 2, an operation unit 4 connected to an end of the hose 3 and provided with a hand operation switch SW and the like, and an operation unit 4 The extension tube 5 is connected from the end of the extension tube 5 and the suction tube 6 is connected to the end of the extension tube 5 and installed on the floor to take in dust. FIG. 1 shows front, rear, side, upper, and lower. Hereinafter, the upper and lower parts are based on this description.
The cleaner body 2 includes an electric blower 2a that generates a suction force, and a dust collecting portion 2b that stores dust collected by the suction force.

The hose 3 connects the operation unit 4 and the cleaner body 2 and serves as a passage for dust sucked from the suction body 6 and the like.

The operation unit 4 includes a handle 4a and a hand operation switch SW. With the hand operation switch SW, ON/OFF of the operation of the electric vacuum cleaner 1, high/medium/weak, and ON/OFF of rotation of the rotary cleaning body 12 can be switched.

The extension pipe 5 is composed of an outer pipe 5a and an inner pipe 5b. The inner pipe 5b is housed inside the outer pipe 5a when the extension pipe 5 is contracted, and the inner pipe 5b is expandable by a mechanism such that the inner pipe 5b comes out of the outer pipe 5a when extended.

A perspective view of the mouthpiece 6 is shown in FIG.

The suction body 6 includes an upper case portion 10 that covers the upper side of the suction body 6, a lower case portion 11 that is located under the upper case portion 10 and that has a suction opening 18 opened on a lower surface facing the surface to be cleaned, and the suction opening 18 The rotary cleaning body 12 provided on the vehicle, a bumper 13 located on the front surface of the suction body 6 for protecting the front surface of the suction body 6 and the front surface of the rotary cleaning body 12, and a drive source 14 for applying a driving force to the rotary cleaning body 12. (Not shown).

The upper case portion 10 and the lower case portion 11 have a role of covering the components, lines, the board, the drive source 14 and the like inside the suction body 6.

The rotary cleaning body 12 is attached to the brush or elastic body of the cleaning member, is located in the vicinity of the front surface of the suction body 6, and does not escape the dust on the floor coming from the front when the suction body 6 moves forward by the rotation of the cleaning member. 6 is responsible for transporting the inside. At that time, power is obtained from the drive source 14 to rotate at high speed.

The bumper 13 is located at the forefront of the suction body 6 and plays a role of protecting the front surface of the suction body 6. Accordingly, even when the suction body 6 collides with a wall or an obstacle, the rotary cleaning body 12 can continue to rotate without damaging the wall or the obstacle and without contacting the wall or the obstacle. Therefore, it is preferable that the bumper 13 be formed of a member having a certain degree of cushioning property. Further, in the vertical direction, it is not always necessary to protect the rotary cleaning body 12 by covering it, and even if the suction body 6 collides with a wall, the bumper 13 is the first to collide. If it is, the vertical dimension does not matter. That is, the shape of the lower end of the bumper 13 that extends to the floor and covers the entire bottom of the rotary cleaning body 12 or the shape of which the lower end is raised to a certain height above the floor so that a large amount of dust can be taken in is taken in by the bumper 13. There is no problem as long as it plays a role of protecting the front surface of the body 6.

The mouthpiece joint 19 is formed in a substantially cylindrical shape, is located on the rear end side of the mouthpiece body 6, and is formed separately from the upper case portion 10 and the lower case portion 11. The end portion of the suction joint 19 is connected to the extension pipe 5 or the operation portion 4 and serves as a flow path for carrying the dust-containing air from the suction inlet 18 to the cleaner body 2 side. The mouthpiece joint 19 is formed of a transparent member (transparent ABS, transparent PP, etc.). When the mouthpiece joint 19 shown in FIG. 3 is an opaque member, and when a toothpick or the like is caught in the S portion, it is difficult to confirm the appearance of the S portion even in P and Q views, but in FIG. As described above, when the mouthpiece joint 19 is a transparent member, the state of the S portion can be easily confirmed by the R view. By easily confirming the state of the S portion, it is possible that a toothpick or the like is caught in the S portion when the dust suction force of the suction body 6 is reduced or when an unusual sound is generated from the suction body 6. It is easy to confirm the cause, and it is possible to easily remove the toothpick or the like caught on the S portion while visually observing it.

Hereinafter, another embodiment of the transparent mouthpiece joint according to the present invention will be described.

The second embodiment of the present invention will be described with reference to FIG. Hereinafter, the configuration is the same as that of the first embodiment except the points described below. In the mouthpiece 6 of the second embodiment, a part of the lower side of the mouthpiece joint 19 is configured by a separate body of the mouthpiece joint cover 20, the mouthpiece joint 19 is formed of an opaque member, and the mouthpiece joint cover 20 is formed of a transparent member. , N, etc., the appearance of the S portion can be easily confirmed by R viewing without being affected by the design surface of the present invention.
