JPH02140122A - Electric cleaner and its floor brush - Google Patents

Abstract

PURPOSE:To obtain an electric cleaner reducing an input by mounting a brush body, a motor, which rotates and drives this brush body, and a pressure sensitive switch, which switches the rotating direction of the motor, to a sucking hood. CONSTITUTION:For the floor brush of the electric cleaner, a brush body 1, a motor 2, which rotates and drives the brush body, and pressure sensitive switches 3 and 4, which switches the rotating direction of the motor, and mounted to a sucking hood 5. The brush body 1 executes the brushing-up of a floor surface by the driving force of the motor 2 and simultaneously travels on the floor surface. The pressure sensitive switches 3 and 4 have function to switch the turning-on off of a power source for the motor 2, which drives the brushing body 1, or the rotating direction of the motor. When both pressure sensitive switches 3 and 4 are turned off, the rotation of the brushing body 1 is stopped. When one pressure sensitive switch is turned on, the brushing body 1 is rotated so as to be traveled in a direction, in which the turned-on switch is in a back direction. When both pressure sensitive switches 3 and 4 are turned on, the rotating direction of the brushing body 1 is inverted and the brushing body is reversely traveled. When the switches 3 and 4 hit an obstacle, the traveling direction is automatically inverted. Thus, the labor of the cleaning is reduced.

Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a vacuum cleaner.

(Prior Art) In conventional vacuum cleaners, the floor brush had to be moved manually. A vacuum cleaner sucks up dust on the floor along with the air, and the floor brush sticks to the floor, so it requires a lot of force to move and clean. It was a demanding job.

(Problems to be Solved by the Invention) An object of the present invention is to provide a vacuum cleaner that reduces the labor required by two people in order to overcome the problems of the prior art.

(Means and effects for solving the problems) The present invention is constructed as follows. In other words, the present invention provides a floor vacuum cleaner characterized in that a suction hood 5 is equipped with a brush body 1, a motor 2 for rotationally driving the brush body, and pressure-sensitive switches 3 and 4 for switching the rotation direction of the motor. It's a brush.

The brush body 1 brushes the floor surface by the driving force of the motor 2, and travels on the floor surface at the same time. The pressure-sensitive switches 3 and 4 have the function of controlling the power source of the motor 2 that drives the brush body 1 and switching the direction of rotation of the motor.

A vacuum cleaner equipped with such a floor brush is best configured as follows, that is, a pressure-sensitive device installed at the forward and backward positions of the suction hood 5 of the vacuum cleaner, When switches 3 and 4 are both off, the rotation of the brush body 1 is stopped, and when one pressure-sensitive switch is on, the brush body 1 is rotated so that the switch works in the backward direction. Yes, if both pressure-sensitive switches 3 and 4 become human.

The vacuum cleaner is configured so that the rotating direction of the brush body 1 is reversed and the brush body 1 runs in the opposite direction.

The present invention will now be explained with reference to explanatory diagrams of the apparatus of the present invention shown in FIGS. 1 to 5. Figures 1 and 2 show brush bodies suitable for sweeping in the left and right direction of entry, and show cases in which there is one brush body and two brush bodies, respectively. Figures 3 and 4 show brush bodies suitable for sweeping in the front and rear directions.

The present invention includes cases in which there is one brush body and cases in which there are two brush bodies, respectively.The present invention also includes cases in which there are three or more brush bodies.

In FIGS. 1 to 4, A is a plan view viewed from the floor side, and B is a conceptual diagram of the mechanism. FIG. 5 is an explanatory diagram of the contact state of the pressure-sensitive switch and the moving direction of the floor brush in the example of FIG. 1B. The method of using the vacuum cleaner of the present invention will be explained with reference to FIG. 5. As shown in FIG. 5A, the suction pipe 6 is tilted to the left in the direction in which the pressure-sensitive switch 3 contacts the floor 7, and as shown in FIG. 5B. When the pressure sensitive switch 3 comes into contact with the floor, the pressure sensitive switch is turned on, and the brush body is rotated in the direction of arrow 10 by the motor 2 and moved to the right by the frictional force of the brush body. At this time, the pressure sensitive switch 3 is at the rear. In FIG. 5C, the pressure-sensitive switch 3 is in contact with the floor and the pressure-sensitive switch 4 is in contact with an obstacle, and these two pressure-sensitive switches are turned on, and the rotation of the motor is reversed. In the fifth drawing, the pressure sensitive switch 4 is in contact with the floor and is in the on state, and the motor 2 is in the on state.
The brush body 1 is driven by the pressure-sensitive switch 4 and moves in the opposite direction to that shown in FIG. 5B. FIG. 5E shows a case where both pressure sensitive switches 3 and 4 are turned off and the motor 2 is stopped.

As described above, the suction pipe 6 is tilted manually and moved by the motor, or the suction hood's pressure-sensitive switch automatically reverses the running direction when it hits an obstacle, so the manual effort for cleaning can be reduced. .

(Effects of the Invention) The floor brush of the vacuum cleaner of the present invention is driven by a motor, and the nine people only have to maintain the posture of the suction tube, as the floor brush is driven by a motor and the vacuum cleaner moves while brushing. There is no need to use . Furthermore, the vacuum cleaner of the present invention sucks up dust on the floor together with air, but the floor brush brushes the floor, resulting in a better cleaning result.

[Brief explanation of the drawing]

Figures 1 to 5 are explanatory views of the device of the present invention, and Figures 1 and 2 show a brush body suitable for sweeping in the left and right direction;
Figures 3 and 4 show brush bodies suitable for sweeping in the front and back direction, respectively, when there is one brush body and when there are two brush bodies, respectively. In the figures, A is a plan view, and B is a conceptual diagram of the mechanism. Fig. 5 is an explanatory diagram of the contact state of the pressure-sensitive switch and the moving direction of the floor brush, where A is stopped, B is when one of the pressure-sensitive switches is being moved by a person, and C is the second one of the pressure-sensitive switches. When the switch is on, D is moving in the opposite direction to B, and E is when both pressure sensitive switches are off and stopped. 1: brush body, 2: motor. 3.4: Pressure sensitive switch, 5: Suction hood. 6: Suction pipe, 7: Floor, 8: Plumb line. 9: Suction hood center line, 10: Brush body rotation direction.
