Abstract

<P>PROBLEM TO BE SOLVED: To provide a method for fixing a rotary part for improving the waste of water and eliminating any other unreasonableness. <P>SOLUTION: In a car washer and a car washing method, regular tap water is introduced to a pressurizing tank body 4 of a cylindrical curved shape through a water supply pipe 1, jetted outwardly in the downward direction from the pressurizing tank body 4 by increasing the pressure, and changed into a spiral wafer flow. An inner tank and an outer tank of the pressurizing tank body 4 are partitioned by a partition plate 6 (a peripheral wall), and a through hole 7 is formed in the partition plate 6 to equalize the pressure in the inner and outer tanks. A plurality of arcuate bent pipes 8, 9 are provided on inner and outer layers in a bent manner, and inclined. Further, the arcuate bent pipes 8, 9 are arranged opposite to each other so as to jet the water flow in the directions opposite to each other from the inner and outer tanks. Cleaning is performed by using the contact resistance friction of the right-handed rotation and the left-handed rotation of the spiral water flow. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

The present invention is a car wash tool for performing washing and washing by injecting tap water having a normal water pressure.

Currently, it is a structure that sprays and rotates a part of a car wash tool attached with scrubber or sponge using water pressure to wash and wash the car body, but it is wasteful due to splashing water and has some problems Yes.

Utility Model Registration No. 3130775

With the current car wash method, it is difficult to compensate for water splashes and water savings only by operation. Structural modification is required.

It is important to keep the rotating part, which is the source of water splashing, stationary, and conversely, it is switched to a method of rotating the water, the structure for that is one form of the car wash according to the present invention, [Claim 1] Supplementary notes (1) A car wash tool for washing a car by injecting tap water,
(2) Sasama water supply pipe that also serves as the operator's operation handle;
(3) A cylindrical curved inner tank connected to the water supply pipe and an outer tank main body pressurizing tank formed so as to surround the outer side of the inner tank (including increasing the number of tanks)
(4) The inner tank and the outer tank are in communication with each other, and the main body pressurizing tank can store water introduced from the water supply pipe in a pressurized state.
(5) an inner arc-shaped curved pipe provided with a plurality of the inner tanks provided in a curved and inclined manner so as to eject a spiral water flow in one direction from the lower end of the inner tank;
(6) A plurality of swirl water flows in the other direction (opposite to the swirl water flow in one direction) are provided in a curved manner and are inclined so as to be ejected from the lower end of the outer tank. And an outer arcuate curved pipe.
Moreover, according to one form of the car-washing tool which concerns on this invention, it can be provided with the splash prevention band of water provided so that the outer periphery of the lower part of the said external tank may be enclosed separately.

(1) According to the present invention, the soft rubber splash prevention band provided on the lower outer side of the main body pressure tank prevents water from splashing and wets the feet and clothes. (2) The present invention changes the water flow into a spiral. And the water pressure is increased in the pressurized tank with a structure in which a plurality of arc-shaped curved pipes are arranged in a cylindrical curved pressurized tank that causes a clockwise water flow from the inner tank to the counterclockwise from the outer tank. Since the curved pipes are ejected all at once, the water flow from the inner tank and the outer tank is strongly reversed in the reverse direction, and most of them collide with twisting and wash using the contact resistance friction to twist the vehicle body. The effect is good because it can be moved by water pipe (handle) operation while polishing.
(3) Just one-touch connection to the water hose, and then the water volume adjustment valve can be used to operate the cleaning with one hand, making it easy and convenient. Preparation for the beginning and end of the work and clean-up are simple and fast.
The time required for the work can be halved, and because it is light using lightweight materials, it can be enjoyed even by women.
(4) It is acceptable if the structure is simple and the accuracy of the parts is constant (medium), and the materials are mainly lightweight materials such as hard and soft plastics, and the number of parts is small, so assembly is easy. There is almost no cause of failure.

BEST MODE FOR CARRYING OUT THE INVENTION

In the present invention, water is supplied to a cylindrical curved main body pressurizing tank through a water supply pipe, the water pressure is increased in the main body pressurizing tank, the inside of the pressurizing tank is separated into an inner tank and an outer tank by a peripheral wall (partition plate), and a through hole is formed in the peripheral wall. A plurality of arc-shaped curved pipes are inclined to increase the water pressure in the main body pressurization tank so as to cause spiral water flows in opposite directions from the inner tank and the outer tank. Therefore, the total cross-sectional area of the curved pipe is kept within a certain standard, and the total number of curved pipes and the pipe diameter are set.
Procedures, configuration,
(1) As shown in FIG. 1, the existing vinyl hose is connected to the water supply pipe with one one-touch joint.
(2) As shown in FIG. 1, two flow rate adjusting valves (open / close cock type) made of plastic or metal are used.
(3) The water supply pipe and the main body pressurizing tank are connected by the three-ball universal joint shown in FIGS.
(4) Create a space for the 5 detergent container chambers in FIGS. 1 and 2, and insert and fix a separate dropper-type soft plastic container for liquid detergent in this case. The lid is sealed as a plug-in type or an open / close type.
(5) The pressure tanks in FIGS. 2 and 4 are divided into the cylindrical curved shape 6 in FIG. 6 and the outer tank peripheral wall (partition plate) as shown in FIG. A through hole 7 in FIG. 3 is provided and distributed.
(6) 8 and 9 in FIG. 2, arc-shaped curved pipes are provided inside the inner tank and the outer tank, penetrating the bottom outside from the height of the center of the main body to the lower part, and further the arc-shaped curved pipes are shown in FIG. It is the most important point to arrange it so that the water flow is concentrated near the center of the lower part in order to cause the vortex as in 8 and 9.
(7) 10 in FIGS. 2 and 3 can explain a small hole for draining the car wash after the work is completed.
(8) 11 in FIG. 2 and FIG. 3 is easy to attach and remove the prevention band by forming it into a groove shape so as to surround the outer periphery of the lower part of the main body with a soft rubber shredded water scattering prevention band. Make it possible.
Based on the above [0007], the total number of arcuate curved pipes and the pipe diameter are set by the following calculation.
The inner diameter of the pipe end water pipe or vinyl hose of a general household is 13 mm, the cross-sectional area of the pipe is 132 mm 2, the opening of the main plug is 40 percent, 52 mm mm, the inner diameter of the bent pipe is 3 mm, 7 mm 2 52 divided by 7 is about 8, and the setting effect is obtained with 4 in the inner tank and 4 in the outer tank.
