Description

[Detailed description of the invention] "Field of industrial application" This invention uses pressure water such as tap water flowing out from a water pipe etc. to rotate the rotary core brush body that constitutes the brush body. When it rotates, water flows out from approximately the center of the core brush body, washing the bodies of automobiles, toilets, the exterior walls of houses, and other cleaning items, and creating a water film between the surfaces of these items and the brush body. The present invention relates to a rotating brush device that uses water pressure to form a brush.

``Prior Art'' Conventionally, as a cleaning device equipped with a brush body that rotates using water pressure, there is a rotating brush body that uses water pressure proposed by the applicant of the present application in Japanese Utility Model Application No. 52-26467. The gist is that the casing is equipped with an impeller that rotates using water pressure, and a rotating brush that simultaneously rotates through the rotation of this impeller.This makes effective use of pressurized water from tap water, etc., and improves handling and work efficiency. The purpose is to provide easy cleaning tools. There is also a car washing and waxing machine published in Utility Model Publication No. 55-3853, which consists of an impeller installed in the main body case and a rotating brush body that rotates at the same time as the impeller. It has a rotating configuration, and is a mechanism that rotates in the horizontal direction (rotation due to surface contact) as described above. The effect is substantially the same as described above. Also, Jikko 56-
There is a rotating brush car wash machine number 4409, and its gist is as follows.
This is a mechanism in which an impeller is rotated using water pressure, and a cylindrical rotating brush is rotated in the cylindrical direction through the rotation of this impeller, and the rotating brush is rotated in the cylindrical direction (rotation by line contact). .
The effect is substantially the same as that described above. Other rotating brush mechanisms include the car wash tool of Utility Model Publication No. 56-25564, whose gist is that a rotating brush installed at the tip of a handle rotates via a transmission means such as a motor and a bevel gear; This mechanism has a rotating brush body that rotates in the horizontal direction via a drive device in the same way as described above. The effect is to speed up and simplify car washing and waxing work.

Furthermore, there is a cleaning device disclosed in Japanese Patent Application Laid-Open No. 49-104461.

``Problems that the invention attempts to solve'' The technical documents detailed above certainly have advantages such as being of great help in speeding up and simplifying car washing and waxing work, and having simplified mechanisms. .

However, when each technical document is examined in detail, there are problems with each.

That is, in Utility Model Application No. 52-26467, the structure of the impeller and the inlet for flowing water is insufficient. There are some problems with the rotational force of the rotating brush and the supply of running water, and there is a risk that water and other deposits may be scattered. Although Utility Model Publication No. 55-3853 is convenient because it uses exhaust gas, it also has disadvantages in terms of use, such as problems with health and exhaust heat countermeasures, and the fact that it is not easy to use in combination with water. It's possible to think about it. In addition, in Utility Model Publication No. 56-4409, since the rotating brush rotates by line contact, the efficiency of operations such as car washing is poor, and in principle, it cannot be used in combination with water, which may have disadvantages in use. Furthermore, in Utility Model Publication No. 56-25564, since it is a mechanical method,
It requires a power source, and in addition to securing it, there is a risk of problems in terms of size and weight, and it is not considered to have sufficient utility value, and as mentioned above, it can be easily used in combination with water. There may be problems in use, such as not being able to do so.

As described above, in the conventional techniques, the combined use of water is not sufficient as a whole, and this poses a serious problem in terms of cleaning work.

The invention of JP-A-49-104461 uses water pressure, and has the advantage that it can be used in combination with water.

However, in this invention, since the tap water is introduced into the center of the impeller chamber, the water pressure is reduced, and as a result, the rotational force of the impeller is not sufficient.

In addition, since the rotating and fixed brushes are not provided with brush grooves for discharging foreign matter, foreign matters located inside the brushes are not smoothly discharged to the outside of the brushes and may damage the surface of the items being cleaned. There are some problems, such as the possibility that

``Means to solve the problem'' Therefore, the present invention first aims to make the cleaning process smoother.
To provide sufficient rotational force to a rotating brush. In addition, while aiming to improve the cleaning ability, we are also trying to eliminate brush scratches on the items to be washed, which may be caused by foreign matter interposed between the brush surface and the surface of the items to be cleaned, such as deposits or other flying debris. to maintain the quality of goods.

In order to achieve these objectives and to create a rotating brush cleaning tool that can exhibit sufficient effects, the following configuration was adopted.

That is, a substantially circular casing, an impeller chamber provided in the casing and having an opening provided at an eccentric position with respect to the rotating shaft, and a boss provided in the impeller chamber and fixed to the rotating shaft. an impeller provided in the impeller chamber so as to be freely protrusive and retractable; a main jet outlet provided in the impeller chamber that opens in the tangential direction of the impeller chamber;
and a fixed outer brush body having brush grooves extending in the radial direction, and a brush groove extending in the radial direction provided below the bottom plate of the casing, which rotates simultaneously through an impeller built in the casing and a rotating shaft. The impeller is composed of a rotary core brush body having a rotating core brush body, and a gripping rod having the main pipe pivotally connected to the casing, and the impeller is and a rotary brush cleaning device using water pressure, characterized in that the core brush body is simultaneously rotated and the running water that has finished working flows out to the free end side of the brush body constituted by the outer brush body and the core brush body. It is.

Next, the tap water that flows out through the branch pipe can be effectively used for cleaning the brush body and other cleaning water, or it can be used as tap water (by controlling the flow to the brush body). To provide an excellent rotating brush cleaning tool.

For this purpose, we adopted the following configuration.

That is, rotary brush cleaning using water pressure is provided with a branch pipe branched from the grip handle, and configured to switch flowing water to the main pipe or the branch pipe via a switching valve provided on the handle handle. Ingredients.

"Function" Next, to explain the function of the present invention, the base end of the grip handle 20 is connected to a water pipe (not shown) via a hose 30.
After connecting to the grip handle 20, grip the grip handle 20.

Then, for example, when cleaning a car (hereinafter a typical example of the article to be washed is a car), the switching valve 24 is first set to the main pipe 21 side. Next, the flow rate adjustment valve 2 provided on the grip handle 20
3 is set to a predetermined value and the water pipe switch is then opened, water flows through the main pipe 21 and is sprayed from the spout 21a at the water pressure set by the regulating valve 23.

In this case, the flowing water flows between the impeller chamber 7 and the boss 5, and this flowing water is injected from the injection port 21a of the main pipe 21 in the direction in which the impeller chamber 7 is connected.

Therefore, first, the impeller chamber 7 and the groove 5a of the boss 5
The liquid is injected toward the connection direction of the first chamber A, which is a substantially sealed triangular chamber formed by the impeller 4 inside and the impeller 4 slightly protruding from the groove 5a.

As a result, the running water injected with a water pressure of about 3 kg of tap water becomes a water pressure of about 9 kg and is applied to the impeller 4, so the impeller 4 starts rotating in a certain direction through this water pressure of about 9 kg. At the same time,
The boss 5 into which the impeller 4 is inserted rotates, and this rotation is transmitted to the rotating shaft 3 to which the boss 5 is fixed. Then, the rotary core brush body 8 fixed to the rotating shaft 3 rotates.

On the other hand, the flowing water spouted into the first chamber A from the spout 21a exerts a rotational action on the impeller 4, and at the same time rotates clockwise in this example (FIG. 1). The next chamber, that is, the second chamber of the triangular chamber in a substantially sealed state consisting of the impeller chamber 7, the impeller 4 that protrudes to the maximum from the groove 5a of the boss 5, and the impeller 4 that protrudes to the maximum from the groove 5a. It moves to A' and its water pressure decreases. In this way, after completing its first work, the running water then
In this example) (Fig. 1), the rotation shifts clockwise, and the impeller 4 slightly protrudes from the impeller chamber 7 and the groove 5a of the boss 5 and the impeller 4 slightly protrudes from the groove 5a of the boss 5. Impeller 4 slightly protruding
The water pressure moves to the third chamber A" of the triangular chamber in a substantially sealed state consisting of and core brush body 8
It flows out to the tip of the brush body 11 of the core brush body 8 through the opening 9 opened in the center. Thereafter, as the core brush body 8 rotates, it is diffused throughout the brush body 11, and further diffused and outflowed to the outer brush body 13 due to the centrifugal force.
Ultimately, the core brush body 8 and the outer brush body 1
It flows out to the entire brush body A composed of 3 and 3. On the other hand, the running water that has reached the third chamber A'' is as described above.
Most of the water flows out from the opening 7a, but some of the flowing water is moved to the next chamber in FIG. The liquid is transferred to the fourth chamber A, which is a triangular chamber in a substantially sealed state, consisting of the impeller 4 that protrudes slightly and the impeller 4 in the same groove 5a, and flows out through the opening 7a. The jetting of the flowing water into the impeller chamber 7, the rotational transition of the impeller 4, the rotation of the boss 5 and the rotating shaft 3, the transition of the flowing water from the first chamber A to the fourth chamber A, and the opening of the impeller chamber 7. The pattern of outflow from the portion 7a is repeated in sequence, resulting in continuous rotation of the core brush body 8 and continuous outflow of water.

Therefore, since a water film is formed between the brush 11 and the car body surface, smooth rotation of the brush 11 and
The occurrence of scratches caused by the sliding movement or rotation trajectory of the brush body B on the body surface is extremely reduced. This is because the water film is considered to have a lubricating effect.

In this way, when water begins to flow out from the core brush body 8, by lightly attaching the brush body B to the car body, the brush body B automatically slides and rotates on the body surface to clean the body. At the same time, remove dirt and deposits from the surface. By the way, these wiped deposits are guided to the brush groove 16 formed in the core brush body 8,
It is successively pushed out in the radial direction, ultimately reaching the outer brush body 13 constituting the brush body B, and then being discharged to the outside via the brush groove 15 formed in the outer brush body 13.

In this case, due to the presence of the outer brush body 13, the water flowing out from the main pipe 21 is not spread out unnecessarily, but on the contrary, it is flowed out evenly over almost the entire tip of the brush body B. It is thought that unnecessary scattering of deposits can be prevented.

When the cleaning is completed through the above operations, the switching valve 24 is operated to cause the water to flow toward the branch pipe 22 in order to allow only water to flow down the cleaning surface. As a result, only water flows out or is injected from the tip of the branch pipe 22, so that a finishing flush can be performed. Also, in the case of simply washing hands, pouring water into a bucket, sprinkling water, etc., tap water can be secured via the branch pipe 22 by doing the same as described above.

When washing is completed as described above, the water pipe switch is closed, and then the hose 30 is removed from the base end of the grip handle 20. This completes the entire cleaning process.

``Example'' Below, an example of the present invention will be described in detail based on the drawings. 1 is a casing that has a circular box shape when viewed from above, and a rotating shaft 3 is connected to the casing 1 via a bearing 2. In this example, the free end side 3a of the rotating shaft 3 is connected to the bottom plate 1 of the casing 1.
b extends below the casing 1.
A boss 5 having an appropriate plate thickness is fixed to the rotating shaft 3, and an impeller 4 that can freely come out and retract is inserted into the radial grooves 5a of the boss 5 (four directions in this example). It is set up. The boss 5 has a mechanism that rotates simultaneously with the rotating shaft 3. Reference numeral 6 denotes a tension spring that always urges the impeller 4 in the direction of the rotating shaft 3.

In the figure, reference numeral 7 denotes an impeller chamber that hangs down from the inner ceiling surface of the casing 1, and this impeller chamber 7 is provided at a position eccentric to the rotating shaft 3. The impeller chamber 7 has a boss 5 fixed to the rotating shaft 3 passing through the impeller chamber 7.
There is also an impeller 4 inserted into the groove 5a of the boss 5. Therefore, when tap water is spouted into the impeller chamber 7 from the spout of the main pipe, which will be described later,
In this case, the flowing water flows between the impeller chamber 7 and the boss 5, and this flowing water is injected from the injection port 21a of the main pipe 21 in the tangential direction of the impeller chamber 7.

Therefore, first, the impeller chamber 7 and the groove 5a of the boss 5
The liquid is ejected in the tangential direction of the first chamber A, which is a substantially sealed triangular chamber formed by the impeller 4 inside and the impeller 4 slightly protruding from the groove 5a.

As a result, the running water jetted out with a water pressure of about 3 kg of tap water becomes a water pressure of about 9 kg and is applied to the impeller 4. As a result, the impeller 4 begins to rotate in a certain direction through this water pressure of approximately 9 kg, and for example, rotates clockwise sequentially until the impeller 4 is located in the groove 5a.
is guided by the inner circumferential surface of the impeller chamber 7, which overcomes the tensile force of the spring 6 and is in an eccentric relationship, and is successively protruded from the groove 5a or recessed through cooperation with the spring 6 and the like. It has a structure in which the so-called impeller 4 moves eccentrically. 7a is an opening provided on one side of the impeller chamber 7, and 7b is a bottom plate of the impeller chamber 7.

In the figure, reference numeral 8 denotes a rotary core brush body fixed to the free end side 3a of the rotary shaft 3, and this core brush body 8 has a substantially annular opening 9 fixed to the rotary shaft 3 at approximately the center. a mounting plate 10 having a
The core brush body 8 rotates simultaneously with the rotation of the rotating shaft 3. Note that the opening 9 is provided with a support member (not shown) extending over the edge thereof.

In the figure, reference numeral 13 denotes a fixed outer brush body installed in an annular manner on the outer periphery of the bottom plate 1b of the casing 1,
A slight gap 14 is formed between this outer brush body 13 and the core brush body 8. The outer brush body 13 is also provided with semicircular brush grooves 15 extending in the radial direction at appropriate intervals, and serves as a path for guiding deposits wiped from the article to be washed through the brush grooves 15. It is something to do.

In the figure, 16 is attached to the core brush body 8 at appropriate intervals.
These brush grooves are opened in the radial direction, and have the same effect as the brush grooves 15. Therefore, together with the brush body 15, the purpose is to discharge the deposits wiped from the article to be washed out of the brush body A.

In the figure, reference numeral 20 denotes a grip handle pivotally attached to the upper surface 1a of the casing 1, and a main pipe 21 is built into the grip handle 20, and a branch pipe 22 is connected to the main pipe 21. Its spout 21
a is a side surface of the impeller chamber 7 and the impeller 4;
is configured to open near the part of the boss 5 that is most immersed in the groove 5a. Therefore, the impeller 4 is rotated by the flowing water jetted from the spout 21a, and then the rotating shaft 3 and the core brush body 8 are rotated substantially simultaneously. In this way, the water that has completed its first work passes from the opening 6 of the impeller 4 through the opening 18 of the casing 1 and then reaches the opening 9 of the core brush body 8. Thereafter, it flows down through the opening 9, from the center of the brush body 11 to its tip, and ultimately to the free end of the brush body B. Reference numeral 23 indicates a regulating valve provided in the main pipe 21, and 24 indicates a switching valve, through which water in the main pipe 21 flows toward the branch pipe 22.

B in the figure is a brush body composed of a core brush body 8 and an outer brush body 13.

Although not shown, the rotating shaft 3 or a fixed shaft may be used. In this case, the fixed shaft is suspended from the inner wall surface of the upper surface 1a of the casing 1 (in this example, the fixed shaft is
In principle, only the peripheral portion of the bottom plate 1b is required), and the impeller 4 is rotatably mounted on this fixed shaft, and the support member hanging from the impeller 4 is fixed to the mounting plate 10 of the core brush body 8. .
The rotation of the impeller 4 is transmitted to the core brush body 8 via this support member.

"Effects of the invention" As detailed above, the present invention has a casing provided on a grip handle equipped with a main pipe and a branch pipe, which allows pressurized water ejected from the main pipe to be ejected in the tangential direction of the impeller chamber. However, an impeller that rotates through the ejected pressure water is provided, a core brush body that rotates simultaneously with the impeller is provided, and an outer brush body that surrounds the core brush body is provided in the casing.

Therefore, sufficient rotational force can be applied to the impeller in the impeller chamber, thereby ensuring reliable and smooth rotation of the core brush body.

This, together with the fact that water flows out almost evenly to the core brush body, ensures reliable and high-speed rotation of the core brush body.

Furthermore, this, combined with the ability to form a water film between the core brush body and the article to be cleaned, ensures smooth rotation of the brush body and automatic sliding transition of the brush body.

Further, the present invention has a configuration in which the core brush body and the outer brush body are each provided with brush grooves in the radial direction.

Therefore, the brush may adhere to the item to be cleaned or may be caused by foreign matter interposed between the brush surface and the surface of the item to be cleaned due to scattering, etc. There are effects such as being able to eliminate scratches caused by rotational movement or rotation locus, and damage to the surface gloss of the article caused by this.

In particular, the present invention includes a rotating shaft provided in the casing and an impeller chamber that is eccentrically related to the rotating shaft, and the impeller that moves eccentrically through a boss installed in the impeller chamber. It is configured to inject tap water in the tangential direction of the impeller chamber.

This makes effective use of that pressure, which is a so-called pressure-increasing action, and there is no risk that the rotation of the core brush body will be stopped even if the brush body is brought into contact with the surface of the article to be washed to some extent. .

Further, the present invention is configured to allow running water to flow out to approximately the center of the brush body through openings provided in the casing, impeller, and core brush body.

As a result, it seems that the inflow and outflow of water is smooth and the formation of the water film becomes more reliable and uniform.

Furthermore, the present invention adopts a configuration in which the core brush body and the outer brush body are individually or similarly provided with brush grooves.

Therefore, the removal of deposits and the outflow of water can be carried out smoothly, and the occurrence of scratches on the articles to be washed due to the above-mentioned foreign matter can be almost completely eliminated.

Further, the present invention has a configuration in which a branch pipe is provided in the grip pipe via a switching valve.

Therefore, the tap water flowing out through the branch pipe,
It can also be effectively used for cleaning brush bodies and as other cleaning water, and is expected to expand the range of applications for rotary brush cleaning tools.
