DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydraulic rotary brush in which tap water or water pumped by a high-pressure pump is used to rotate a brush by the water pressure. And waxing.

[0002]

2. Description of the Related Art There has been a hydraulic rotary brush for rotating a brush with the water pressure of tap water. One example is Shokai 5
No. 5,114,243 discloses a rotating brush. As shown in FIGS. 8A and 8B, a rotor 82 is rotatably provided at an eccentric position of a housing space 81 in a housing 80, and a vane 83 is slidably mounted on the rotor 82, so that a housing space is provided. When tap water is supplied into the inside 81, the vane 83 receives water pressure, and the vane 83 and the rotor 82 rotate.
Rotates, the centrifugal force causes the vane 83 to slide outward, and the outer peripheral surface 84 of the vane 83 comes into contact with the inner peripheral surface 85 of the accommodation space 81. In this state, the vane 83 and the rotor 82 continue to rotate, The brush 86 attached to the center of the roller 82 rotates.

[0003]

However, since the tap water pressure is usually not so high, the rotation speed of the rotor 82 rotated by the water pressure is not so high.
There is no centrifugal force to slide 3 out. For this reason, the outer peripheral surface 84 of the vane 83 does not reliably contact the inner peripheral surface 85 of the housing space 81, and a gap is formed between the two, and water leaks from the gap, so that the rotor 82 becomes more difficult to rotate, Eventually, there is a problem that the brush 86 does not rotate.

[0004]

[0023]

Fourth Embodiment of the Invention The hydraulic rotary brush according to the present invention has a circular arc shape on the upper surface of the cover 33 and outside the brush 4 and on the side of the water supply port 5 as shown by the imaginary line in FIG. By attaching the liquid repelling device 24, it is possible to prevent water or detergent from being applied to the user during use of the hydraulic rotary brush. The liquid repelling device 24 is suitably made of a resin plate or a metal plate. Although the illustrated shape of the liquid guard 24 is arc-shaped, the shape may be other than that.

[0024]

Usage Example 1 To use the hydraulic rotary brush shown in FIGS. 1 to 4, for example, a hose is connected to the water supply port 5, and tap water or water pumped by a high-pressure pump is supplied to the water supply port 5. .
This water flows into the storage section 6 as shown by the arrow in FIG. 3 and hits the vane 3 to rotate the vane 3 and the rotor 2. The rotation of the rotor 2 causes the vanes 3 in the guide grooves 12 of the rotor 2 to rotate one after another. As a result, the water flowing into the storage section 6 is sequentially sent in the rotation direction by the respective vanes 3 and flows out from the drainage channel 10 to the flowing water port 9.
As described above, the water flows in the order of the drain passage 10-the communication port 38-the diffusion portion 39-the water hole 50 of the brush 4-the brush bristles 52. At this time, the water also flows into the space 44 of the rotor 2, but the water flows into the depressurized portion 34 formed on the outer peripheral surface 17 of the vane receiving shaft 8, so that when the rotor 2 rotates, Is reduced, and there is no particular hindrance to the rotation of the rotor 2.
Further, since the brush 4 rotates with the rotation of the rotor 2, it is possible to clean a car or a floor of a house with the brush 4 while supplying water to the brush 4. In this case, the washing can be performed after the detergent is applied to the floor of the automobile or the house, or while the detergent is applied. In the hydraulic rotary brush of FIG. 4, since the liquid protector 24 is provided outside the housing 1 and outside the brush 4 and on the side of the water supply port 5, it is possible to work with the hand on the side of the water supply port 5. In this case, even if the brush 4 rotates, water drops are less likely to be applied to the body.

[0025]

[Usage Example 2] In the case of the hydraulic rotary brush shown in FIG. 5, two ways of use are possible by switching the water flow switching valve 21. One of them is similar to the hydraulic rotary brush in Fig. 1,
A method of rotating the brush 4 while supplying tap water or water pumped by a high-pressure pump to the brush 4, and another method is to supply the brush 4 without supplying tap water or water pumped by a high-pressure pump to the brush 4. 4 is a method of rotating. In the former case, the water flow switching valve 21 is lowered as shown in FIG. 5, the drain passage 10 is opened, and the return passage 53 is closed. In this state, if tap water or water pumped by a high-pressure pump is allowed to flow through the water supply port 5, the water is discharged as shown in FIG.
The brush 4 rotates by flowing along exactly the same path as in the case (1), and water is supplied to the brush. In the latter case, the water flow switching valve 21 is raised, the drainage passage 10 is closed, and the return passage 53 is opened. When water flows through the water supply port 5 in this state, the water rotates the rotor 2 to rotate the brush 4, but the water that has rotated the rotor 2 flows to the return path 53 and does not flow to the drain path 10 side. Therefore, the brush 4 rotates but no water is supplied to the brush 4. Therefore, when washing a car with detergent,
If only the brush 4 is rotated without supplying tap water or water pumped by a high-pressure pump to the brush 4, the detergent does not flow and the detergent is not wasted.

Further, as shown by a virtual line in FIG. 5, a cleaning liquid container 60 can be detachably mounted near the water supply port 5 of the housing 1 to mix the cleaning liquid with water. By doing so, the cleaning liquid diluted with water flows to the brush 4, and the cleaning effect is enhanced.

[0027]

[Usage Example 3] In the case of the hydraulic rotary brushes of FIGS. 6 and 7, the vane receiving shaft 8 is formed separately from the housing portion 6 of the housing, but is used similarly to the hydraulic rotary brushes of FIGS. can do. In the case of the hydraulic rotary brush of FIGS. 6 and 7, since the discharge groove 22 is provided on both or one of the upper surface of the housing 6 and the inner surface of the lid 32 of the housing 1, the brush flows into the housing 6. The contaminants are easily discharged from the discharge groove 22.

[0028]

The hydraulic rotary brush according to the first and second aspects of the present invention has the following effects. 1. The outer peripheral surface 14 of the vane 3 is always in contact with the inner peripheral surface 15 of the housing portion 6, and the inner peripheral surface 16 of the vane 3 is always in contact with the outer peripheral surface 17 of the vane receiving shaft 8, so that a large number of small chambers are formed in the housing portion 6. 1
8, the tap water or the water pumped up by the high-pressure pump sent into the storage unit 6 does not leak from the small chamber 18, and the rotor 2 uses the water pressure of the tap water or the water pumped up by the high-pressure pump. Rotate reliably.

The hydraulic rotary brush according to the third aspect of the present invention has the following effects. 1. There is a water flow switching valve 21 that can switch the flow of the liquid flowing out of the flowing water port 9 between the drain path 10 side and the return path 53 side. The brush 4 can be rotated while supplying water, or the brush 4 can be rotated without supplying tap water or water pumped by a high-pressure pump to the brush 4. Therefore, the water flow switching valve 21 can be switched and used according to the application.

The hydraulic rotary brush according to claim 4 of the present invention has the following effects. 1. Since the discharge groove 22 is provided on at least one of the upper surface of the housing portion 6 and the inner surface of the lid 32 of the housing 1,
The contaminants flowing into the inside are easily discharged from the discharge groove 22, and the cleaning ability of the rotating brush is further improved.

The hydraulic rotary brush according to claim 5 of the present invention has the following effects. 1. Since the liquid protector 24 is provided outside the housing 1 and outside the brush 4 and on the side of the water supply port 5, the brush 4 is rotated when the work is carried out by holding it with the hand on the side of the water supply port 5. Even water drops are less likely to hit the body.
