Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a vacuum cleaner in which a rotating brush is housed in a floor suction device, and particularly relates to a vacuum cleaner in which a motor is built into the floor suction device. It is something.

[Conventional technology]

Conventionally, as shown in Figure 2, this type of vacuum cleaner has a hose (2) and a hand pipe (3) on the vacuum cleaner body (1).
and a floor suction machine (
5) contains a rotating brush (not shown) that sweeps the floor surface, such as a carpet, by tapping and sweeping it with the force of the suction wind.

However, when using a rotating brush, the vacuum cleaner's original dust-collecting ability is forced to decline, and the rotating brush may stop when cleaning long-pile carpets. ) has a built-in motor.

Figure 3 is an electrical circuit diagram of a floor suction machine (5) that houses a rotating brush with a built-in motor, and (6) shows a motor (not shown) connected to the hand pipe (3) shown in Figure 2. The motor operation switch (8) in the floor suction machine (5) is installed together with the operation switch (7). shows a rectifier that converts the DC output into DC, and the motor (9) is driven by the DC output.
Thereby, it is possible to increase the rotational force for the rotating brush and improve the dust collection ability.

(Problems to be Solved by the Invention) However, as mentioned above, in conventional vacuum cleaners, due to high noise during operation, it is difficult to determine whether or not the rotating brush is being rotated by the drive of the motor (9). It is difficult to judge, and since the speed of this motor (9) is not eliminated and is always constant, it should be used correctly depending on long pile carpets, short carpets, tatami mats, floors, etc. I couldn't do it.

This invention was made in order to solve the above-mentioned problems in the conventional example, and it is possible to change the rotational speed of the motor built into the floor suction machine according to the object to be cleaned, and also to display this. To provide a vacuum cleaner whose operating condition can be visually checked.

(Means for Solving the Problems) A vacuum cleaner according to the present invention is a vacuum cleaner in which a motor is built into a floor suction device that accommodates a rotating brush.
A switch for controlling the speed of the motor is provided, and a display is provided that changes the display format depending on the speed control.

[Effect]

According to the vacuum cleaner of the present invention, the speed of the motor built into the floor suction machine can be controlled depending on the object to be cleaned, and this can be visually confirmed by the display.

[Embodiment] Hereinafter, an embodiment of the present invention will be described based on FIG. 1, in which the same parts as in FIG. 3 are denoted by the same reference numerals. In Fig. 1, (10) is a motor (9) installed in the hand pipe (3) shown in Fig. 2 in the same way as the motor operation switch (6) in the conventional floor suction machine (5). ), when the switch is connected to the contact S1, the motor (9) is stopped and controlled to be suitable for cleaning such as folding, and when it is connected to the contact S2, it is controlled to stop the motor (9) depending on the cleaning object, for example. By operating the motor (9) strongly for a while so that it is suitable for cleaning carpets with long piles, and when connected to contact S3, the resistance (11) is set so that it is suitable for cleaning carpets with short piles.
) By supplying power to the motor (9) through the motor (9), the motor (9) can be operated at low speed, and by selectively using the motor (9) depending on the object to be cleaned, its dust collection ability can be improved.

(12) is a lamp as an indicator whose display format changes according to the speed control of the motor (9), and this lamp is used as a display for the floor suction machine (5) as shown in FIG. ) is provided on the surface of the motor (9) so that it can be visually checked during operation.For example, the switch of the speed control changeover (10) is connected to the contact S. When the motor (9) is stopped, the light is turned off and the switch is connected to the contact S2. It lights up during strong operation, and when it is connected to contact S3, the brightness is reduced by inserting a resistor (11) during weak operation, and the display format is different. It has become.

Therefore, the operating condition of the motor (9) and the rotating brush can be easily recognized by the display form.

〔Effect of the invention〕

As described above, according to the present invention, the speed of the motor built in the floor suction machine can be controlled depending on the object to be cleaned, and the operating condition of the motor can be visually checked.
