Abstract

PURPOSE:To eliminate complicatedness of switching operation in accordance with a cleaning surface by detecting a condition of the cleaning surface, coming into contact with a floor brush, and controlling an electromagnetic device which protrudes and sinks a wiper device from a bottom surface of the floor brush. CONSTITUTION:A wiper device 7 has a hairbrush 7a, and an electromagnetic device 8 is provided in upper part both sides of the wiper device 7, adapting a movable part 8a to the device 7. A spring 9 pulls the wiper device 7 to the upper. A microswitch 10 is a detector device having an actuator 10a. A control unit 11 is electrically connected to the microswitch 10 and the electromagnetic device 8. In the case of a cleaning surface formed in a wooden floor and straw matting, the actuator 10a of the microswitch 10 is adapted to the cleaning surface turning off the microswitch 10. In case of the hairbrush in transfer to a carpet, the actuator 10a sinks in hairs of the carpet, turning on the microswitch 10, and the control unit 11 protrudes a bar of movable part 8a of the electromagnetic device 8 and a bar of the wiper device 7 from the bottom surface of a floor brush main unit 1 against tension of the spring 9.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] This invention relates to a floor brush, and particularly to improved operability.

[Conventional technology]

A conventional floor brush will be explained in FIG. In the figure, (1) is the floor brush body, (2) is the suction port, and (3) is the wiping device, which has a bristle brush (3a). (4) is a switching lever.

Next, the operation will be explained. When the floor brush main body (1) is connected to a vacuum cleaner (not shown) and the vacuum cleaner main body is operated, intense air is sucked through the suction port (2).

Then, by applying the floor brush body (1) to the cleaning surface, the dust on the cleaning surface will be removed to the suction port (2)! 1lvL air is sucked into the vacuum cleaner body. At this time, if the surface to be cleaned is 1 tatami mat between the boards, use the switching lever (4) to make the bristle brush (3a) sink into the lower surface of the floor brush body (1), and if the surface is floor brush, make it stick out.

[Problem to be solved by the invention]

With conventional floor brushes, when moving from the 1 tatami mat between the boards to the jutan and vice versa, the bristle brush (3a) is used by the switching lever (4).
There was a problem in that it was difficult to operate because it should not appear.

This invention was made to solve the above-mentioned problems, and an object thereof is to obtain a floor brush that can automatically control the appearance and retraction of the wiping device.

[Means to solve the problem]

The floor brush according to the present invention includes a floor brush main body, a wiping device provided on the lower surface of the floor brush main body, an electromagnetic valve for causing the wiping device to protrude and retract from the lower surface of the floor brush main body, and a cleaning surface provided in contact with the floor brush main body. The electromagnetic device is equipped with a detection device that detects the state, and a control device that controls the electromagnetic device according to the output of the detection device.

[Effect]

In the floor brush of the present invention, a detection device that detects the state of the cleaning surface in contact with the floor brush body outputs an output to the control device, and the control device controls the electromagnetic device, so that the wiping device Appears from the bottom.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to the drawings. 1st
In Figures to Figure 3, (5) is the floor brush body.

(61 is the suction port, (7) is the wiping device, and the 0-bristle brush (
7a). (8) is an electromagnetic device provided on both sides of the upper part of the wiping device (7) and brought into contact with the movable part (8a);
) is a spring that pulls the wiping device (7) upward, (
[ is a microswitch which is a detection device and has an actuator (10a). αυ is a control device electrically connected to the microswitch aυ and the electromagnetic device (8).

Next, the operation will be explained. The cleaning surface is between the boards.

In the case of tatami mats, use the micro switch O (L actuator (
10a) hits the cleaning surface, turn the micro switch αG to O.
I'm using FF. When the floor brush is moved to the wool, the actuator (10a) sinks into the wool and turns on the micro switch QG. This output is received by the control device αO, and the movable part (8a) of the electromagnetic device (8)
) to squeeze out. This movable part (8a) has a spring (9
) against the pulling force of the wiping device (the sword is squeezed out from the bottom surface of the floor brush body fl). Also, if the cleaning surface moves to 1 tatami between the boards, the actuator (10a) will hit the cleaning surface and turn off the micro switch t11N, so 1. The movable part (8a) of the electromagnetic device (8) sinks, and the wiping device (7)
Since the wiping device is recessed into the lower surface of the floor brush main body (1), the wiping device is automatically controlled according to the condition of the surface to be cleaned, thereby eliminating the cumbersome operation.

Furthermore, in the above embodiment, an actuator (1 oa
) was used.

A light detection device such as a light emitting device and a light receiving device that detect the condition of a floor surface based on the reception rate of light, or a sonic detection device such as a sonic wave generator and a sonic wave reception device that detect the condition of a floor surface based on the reception rate of sound waves. Electrical devices may also be used.

Further, in the above embodiment, the wiping device (7) was moved up and down, but as shown in FIGS. 4 and 5, the shaft (7)
b) so that the electromagnetic device (8) is located on the side so that the movable part (8a) rotates the wiping device (7).

Further, in the above embodiment, the wiping device (7) and the electromagnetic device (8) are separate bodies, but they may be connected mechanically.

Further, in the above embodiment, the wiping device (7) includes a bristle brush (7a).
However, a rubber spatula or the like may also be used, and the type is not limited to this.

〔Effect of the invention〕

As described above, according to the present invention, the detection device detects the state of the cleaning surface and outputs it to the control device, and the control device controls the electromagnetic device to cause the wiping device to protrude and retract from the bottom surface of the floor brush body. , it is possible to obtain an effect of high practical value by eliminating the cumbersomeness of operation.
